PRELIMINARY — SUBJECT TO COMPLETION — DATED July 7, 2011
 
         
     
 
PROPOSED MERGER — YOUR VOTE IS VERY IMPORTANT
 
Allied World Assurance Company Holdings, AG (“Allied World”) and Transatlantic Holdings, Inc. (“Transatlantic”) have agreed to a “merger of equals” business combination of the two companies pursuant to the terms of an Agreement and Plan of Merger, dated as of June 12, 2011 (the “merger agreement”). Pursuant to the terms of the merger agreement, GO Sub, LLC, a wholly-owned subsidiary of Allied World (“Merger Sub”), will merge with and into Transatlantic (the “merger”), with Transatlantic surviving as a wholly-owned subsidiary of Allied World. Upon completion of the merger, Allied World will be the parent company of Transatlantic and Allied World’s name will be changed to “TransAllied Group Holdings, AG”.
 
Upon completion of the merger, Transatlantic stockholders will be entitled to receive 0.88 registered shares (Namenaktien) of Allied World (“Allied World shares”) for each share of Transatlantic common stock, par value $1.00 per share (“Transatlantic common stock”), that they own immediately prior to the effective time of the merger (the “exchange ratio”), together with cash in lieu of Allied World fractional shares. This exchange ratio is fixed and will not be adjusted to reflect stock price changes prior to the closing of the merger. Based on the closing price of Allied World shares on the New York Stock Exchange, Inc. (the “NYSE”) on June 10, 2011, the last trading day before public announcement of the merger, the exchange ratio represented approximately $51.10 in value for each share of Transatlantic common stock. Based on the closing price of Allied World shares on the NYSE on          , 2011, the latest practicable trading day before the date of this joint proxy statement/prospectus, the exchange ratio represented approximately $     in value for each share of Transatlantic common stock. Allied World shareholders will continue to own their existing Allied World shares after the merger. Allied World shares are currently traded on the NYSE under the symbol “AWH,” and Transatlantic common stock is currently traded on the NYSE under the symbol “TRH.” We urge you to obtain current market quotations of Allied World shares and Transatlantic common stock.
 
Based on the estimated number of Allied World shares and Transatlantic common stock that will be outstanding immediately prior to the closing of the merger, we estimate that, on a fully diluted basis, upon such closing, former Allied World shareholders will own approximately 42% of the combined company and former Transatlantic stockholders will own approximately 58% of the combined company.
 
Allied World and Transatlantic will each hold a meeting of their respective shareholders (the “Special Shareholder Meetings”) in connection with the merger. At the extraordinary general meeting of Allied World shareholders, (the “Allied World Special Shareholder Meeting”), Allied World shareholders will be asked to vote on proposals to increase the ordinary share capital, conditional share capital and authorized share capital of Allied World, a proposal to approve the issuance of Allied World shares to Transatlantic stockholders, a proposal to amend the Allied World Articles of Association to change Allied World’s name to “TransAllied Group Holdings, AG”, a proposal to elect directors to the combined company’s board of directors upon completion of the merger, and certain other related proposals. At the special meeting of Transatlantic stockholders (the “Transatlantic Special Shareholder Meeting”), Transatlantic stockholders will be asked to vote on the adoption of the merger agreement and certain other related proposals.
 
We cannot complete the merger unless the holders of each company’s shares approve the proposals related to the merger. Your vote is very important, regardless of the number of shares you own. Whether or not you expect to attend either Special Shareholder Meeting in person, please submit a proxy to vote your shares as promptly as possible so that your shares may be represented and voted at the Allied World or Transatlantic Special Shareholder Meeting, as applicable.
 
The Allied World board of directors has unanimously approved the merger agreement and determined that the merger agreement and the transactions contemplated thereby are in the best interests of Allied World. The Allied World board of directors unanimously recommends that the Allied World shareholders vote (i) “FOR” the proposals to increase the ordinary share capital, (ii) “FOR” the

proposal to issue shares of Allied World in the merger, (iii) “FOR” the proposal to amend Allied World’s Articles of Association to change the company’s name, (iv) “FOR” the proposal to elect directors to the combined company’s board of directors, (v) “FOR” the proposal to effect a capital reduction to allow for the payment of a dividend to the combined company’s shareholders after the completion of the merger and (vi) “FOR” the proposal to approve the fourth amendment and restatement of the Allied World Third Amended and Restated 2004 Stock Incentive Plan.
 
The Transatlantic board of directors has unanimously approved the merger agreement and determined that the merger agreement and the transactions contemplated thereby are in the best interests of Transatlantic and its stockholders. The Transatlantic board of directors unanimously recommends that Transatlantic stockholders vote (i) “FOR” the proposal to adopt the merger agreement, (ii) “FOR” the proposal to approve adjournment of the Transatlantic Special Shareholder Meeting, if necessary or appropriate, to solicit additional proxies and (iii) “FOR” the proposal to approve, on an advisory (non-binding) basis, the compensation that may be paid or become payable to Transatlantic’s named executive officers in connection with the merger and the agreements and understandings pursuant to which such compensation may be paid or become payable.
 
The obligations of Allied World and Transatlantic to complete the merger are subject to the satisfaction or waiver of several conditions. The accompanying joint proxy statement/prospectus contains detailed information about Allied World, Transatlantic, the meetings, the merger agreement and the merger. You should read this joint proxy statement/prospectus carefully and in its entirety before voting, including the section entitled “Risk Factors” beginning on page 22.

QUESTIONS AND ANSWERS
 
The following are some questions that you, as a shareholder of Allied World Assurance Company Holdings, AG (an “Allied World shareholder”) or a stockholder of Transatlantic Holdings, Inc. (a “Transatlantic stockholder”), may have regarding the merger and the other matters being considered at the contemplated meetings and the answers to those questions. Allied World Assurance Company Holdings, AG (“Allied World”) and Transatlantic Holdings, Inc. (“Transatlantic”) urge you to carefully read the remainder of this joint proxy statement/prospectus because the information in this section does not provide all the information that might be important to you with respect to the merger and the other matters being considered at the Special Shareholder Meetings. Additional important information is also contained in the Annexes to, and the documents incorporated by reference into, this joint proxy statement/prospectus.
 
Q: Why am I receiving this joint proxy statement/prospectus?
 
A: Allied World and Transatlantic have agreed to a strategic business combination pursuant to the terms of the merger agreement that is described in this joint proxy statement/prospectus. A copy of the merger agreement is included in this joint proxy statement/prospectus as Annex A.
 
In order to complete the merger, among other things:
 
• Allied World shareholders must approve the proposal to increase Allied World’s ordinary share capital pursuant to article 3a(a) of the Articles of Association of Allied World Assurance Company Holdings, AG (the “Allied World Articles”), by CHF          (equaling USD          ) to CHF          (equaling USD          ) by the issuance of           registered shares (Namenaktien) of Allied World Assurance Company Holdings, AG (“Allied World shares”) to Transatlantic stockholders pursuant to, and only in connection with, the merger as contemplated by the merger agreement, including the exclusion of all preferential subscription rights to which Allied World shareholders may be entitled (the “article 3 share capital increase proposal”); the contributions for the new registered shares are paid by converting existing reserves (Kapitalreserven) into share capital;
 
• Allied World shareholders must approve the proposal to increase Allied World’s conditional share capital pursuant to article 5(a) of the Allied World Articles by CHF          (equaling USD          ) to CHF          (equaling USD          ), only in connection with the completion of the merger (the “article 5 share capital increase proposal”);
 
• Allied World shareholders must approve the proposal to increase Allied World’s authorized share capital pursuant to article 6(a) of the Allied World Articles by CHF          (equaling USD          ) to CHF          (equaling USD          ), only in connection with the merger (the “article 6 share capital increase proposal” and, together with the article 3 share capital increase proposal and the article 5 share capital increase proposal, the “share capital increase proposals”);
 
• Allied World shareholders must approve the proposal to issue Allied World shares to Transatlantic stockholders pursuant to the merger and as contemplated by the merger agreement as required by NYSE rules (the “NYSE share issuance proposal”);
 
• Allied World shareholders must approve the proposal to amend the Allied World Articles to change Allied World’s name to “TransAllied Group Holdings, AG” (Allied World and Transatlantic after the merger, “TransAllied” or the “combined company”) immediately following, and conditioned upon, the completion of the merger (the “name change proposal”);
 
• Allied World shareholders must approve the proposal to elect (x) three Class II directors to hold office commencing upon the completion of the merger and ending upon TransAllied’s annual general meeting of shareholders (“Annual Shareholder Meeting”) in 2012, (y) four Class III directors to hold office commencing upon the completion of the merger and ending upon TransAllied’s Annual Shareholder Meeting in 2013 and (z) four Class I directors to hold office commencing upon the completion of the merger and ending upon TransAllied’s Annual Shareholder Meeting in 2014 (the “election of directors proposal”); and

Table of Contents

 
• Transatlantic stockholders must approve the proposal to adopt the merger agreement (the “adoption of the merger agreement proposal”).
 
In addition, Allied World is soliciting proxies from its shareholders with respect to two additional proposals, the approval of the second proposal is conditioned upon the completion of the merger; however, completion of the merger is not conditioned upon receipt of either of these approvals:
 
• Allied World shareholders are being asked to consider and vote upon the proposal to effect a capital reduction to allow for the payment of a dividend to the combined company’s shareholders after the completion of the merger (the “capital reduction proposal”); and
 
• Allied World shareholders are being asked to consider and vote on the proposal to amend and restate the Allied World Third Amended and Restated 2004 Stock Incentive Plan (the “Stock Incentive Plan”), the form of which is included as Annex E to this joint proxy statement/prospectus, to, among other things, increase the number of shares reserved for issuance under the Plan and to extend the Plan’s termination date, effective upon the completion of the merger (the “Stock Incentive Plan proposal”).
 
In addition, Transatlantic is soliciting proxies from its stockholders with respect to two additional proposals; completion of the merger is not conditioned upon receipt of these approvals:
 
• Transatlantic stockholders are being asked to consider and vote upon the proposal to adjourn the special meeting of Transatlantic stockholders (the “Transatlantic Special Shareholder Meeting”), if necessary or appropriate, to solicit additional proxies if there are not sufficient votes to approve the adoption of the merger agreement proposal (the “adjournment proposal”); and
 
• Transatlantic stockholders are being asked to consider and vote on a proposal, on an advisory (non-binding) basis, to approve the compensation that may be paid or become payable to Transatlantic’s named executive officers in connection with the merger, and the agreements and understandings pursuant to which such compensation may be paid or become payable, as described in the section entitled “The Merger — Interests of Transatlantic’s Directors and Executive Officers in the Merger — Golden Parachute Compensation” (the “golden parachute proposal”).
 
Allied World and Transatlantic will hold separate meetings of the holders of their shares to obtain these approvals. This joint proxy statement/prospectus, including its Annexes, contains and incorporates by reference important information about Allied World and Transatlantic, the merger and the meetings of the holders of shares of Allied World and Transatlantic. You should read all the available information carefully and in its entirety.
 
Q: What will I receive in the merger?
 
A: Allied World Shareholders:  If the merger is completed, Allied World shareholders will not receive any merger consideration and will continue to hold the shares of Allied World which they currently hold. The share capital of Allied World consists of the outstanding Allied World shares and non-voting participation certificates (“Allied World non-voting shares”).
 
Transatlantic Stockholders:  If the merger is completed, holders of Transatlantic common stock will receive 0.88 Allied World shares for each share of Transatlantic common stock they hold at the effective time of the merger. Transatlantic stockholders will not receive any Allied World fractional shares in the merger. Instead, Allied World will pay cash in lieu of any Allied World fractional shares that a Transatlantic stockholder would otherwise have been entitled to receive.
 
Following the merger, the combined company’s common shares will be traded on the NYSE under the symbol “TAG”.
 
Q: What is the value of the merger consideration?
 
A: Because Allied World will issue 0.88 Allied World shares in exchange for each share of Transatlantic common stock, the value of the merger consideration that Transatlantic stockholders receive will depend on the price of Allied World shares at the effective time of the merger. That price will not be known at the time of the Special Shareholder Meetings and may be more or less than the current price or the price at the time of the meetings. We urge you to obtain current market quotations of Allied World shares and Transatlantic common stock.

Q: When and where will the meetings be held?
 
A: Allied World Shareholders:  The extraordinary general meeting of Allied World shareholders (the “Allied World Special Shareholder Meeting”) will be held at Allied World’s corporate headquarters, Lindenstrasse 8, 6340 Baar, Zug, Switzerland, on          , 2011, at [2:00] p.m. local time.
 
Transatlantic Stockholders:  The Transatlantic Special Shareholder Meeting will be held at          , on          , 2011, at [8:00] a.m. local time.
 
Q: Who is entitled to vote at the meetings?
 
A: Allied World Shareholders:  The Allied World board of directors has set          , 2011 (the “Allied World record date”) as the record date for the Allied World Special Shareholder Meeting. Only holders of record of Allied World shares as of the close of business on the Allied World record date are entitled to notice of, and to vote at, the Allied World Special Shareholder Meeting or any adjournment or postponement of the Allied World Special Shareholder Meeting. Holders of Allied World non-voting shares will receive this joint proxy statement/prospectus but are not entitled to participate in or vote at the Allied World Special Shareholder Meeting. As of the Allied World record date, there were           Allied World shares and          Allied World non-voting shares outstanding. Beneficial owners of Allied World shares and shareholders registered in the Allied World share register with Allied World shares at the close of business on the Allied World record date are entitled to vote at the Allied World Special Shareholder Meeting, except as provided below. If you ask to be registered as a shareholder of record with respect to your Allied World shares in Allied World’s share register and become a shareholder of record for those shares (as opposed to a beneficial holder of shares held in “street name”) after the Allied World record date, but on or before          , 2011, and want to vote those shares at the Allied World Special Shareholder Meeting, you will need for identification purposes to obtain a proxy from the registered voting rights record holder of those shares as of the Allied World record date to vote your shares in person at the Allied World Special Shareholder Meeting. Alternatively, you may also obtain the proxy materials by contacting the Corporate Secretary, attention: Wesley D. Dupont, at Allied World Assurance Company Holdings, AG, Lindenstrasse 8, 6340 Baar, Zug, Switzerland, or via e-mail at secretary@awac.com. If you are a record holder of Allied World shares (as opposed to a beneficial holder of shares held in “street name”) on the record date but sell your Allied World shares prior to          , 2011 you will not be entitled to vote those shares at the Allied World Special Shareholder Meeting.
 
Transatlantic Stockholders:  The Transatlantic board of directors has set          , 2011 (the “Transatlantic record date”) as the record date for the Transatlantic Special Shareholder Meeting. Only holders of record of outstanding shares of Transatlantic common stock as of the close of business on the Transatlantic record date are entitled to notice of, and to vote at, the Transatlantic Special Shareholder Meeting or any adjournment or postponement of the Transatlantic Special Shareholder Meeting. As of the Transatlantic record date, there were           shares of Transatlantic common stock outstanding.
 
Q: What constitutes a quorum at the meetings?
 
A: Allied World Shareholders:  A quorum is required to transact business at the Allied World Special Shareholder Meeting. Without giving effect to the limitation on voting rights described below, the quorum required at the Allied World Special Shareholder Meeting is that two or more persons present in person and representing in person or by proxy throughout the meeting more than 50% of the total issued and outstanding Allied World shares are present throughout the meeting. The Allied World board of directors or chairman of the Allied World board of directors may postpone the meeting with sufficient factual reason, provided that notice of postponement is given to the shareholders in the same form as the invitation before the time for such meeting. A new notice is then required to hold the postponed meeting. Under Swiss law, a general meeting of shareholders for which a notice of meeting has been duly published may not be adjourned without publishing a new notice of meeting.
 
With respect to the article 3 share capital increase proposal, the article 5 share capital increase proposal, the article 6 share capital increase proposal, the name change proposal, the election of directors proposal and the capital reduction proposal, abstentions will be counted toward the presence of a quorum at, but


v


Table of Contents

will not be considered votes cast on any of these proposals brought before the Allied World Special Shareholder Meeting. With respect to the NYSE share issuance proposal and the Stock Incentive Plan proposal abstentions will count as votes cast on these proposals brought before the Allied World Special Shareholder Meeting.
 
While “broker non-votes” would generally be counted for purposes of establishing a quorum for the Allied World Special Shareholder Meeting, because the nature of the proposals to be voted on by the Allied World shareholders at the Allied World Special Shareholder Meeting are all “non-routine” matters for which your broker does not have discretionary voting authority, there will be no “broker non-votes” for purposes of the Allied World Special Shareholder Meeting.
 
Transatlantic Stockholders:  Stockholders who hold shares representing at least a majority of the aggregate voting power of the outstanding capital stock entitled to vote at the Transatlantic Special Shareholder Meeting must be present in person or represented by proxy to constitute a quorum for the transaction of business at the Transatlantic Special Shareholder Meeting. The Transatlantic stockholders, by a majority vote at the meeting by the holders of Transatlantic common stock entitled to vote and present in person or by proxy, whether or not a quorum is present, may adjourn the meeting to another time or place without further notice unless the adjournment is for more than 30 days or, if after the adjournment, a new record date is fixed for the adjourned meeting, in which case a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the adjourned meeting.
 
Abstentions will be included in the calculation of the number of shares of Transatlantic common stock represented at the Transatlantic Special Shareholder Meeting for purposes of determining whether a quorum has been achieved. However, broker non-votes will not be included in the calculation of the number of shares of Transatlantic common stock represented at the Transatlantic Special Shareholder Meeting for purposes of determining whether a quorum has been achieved.
 
Q: How do I vote?
 
A: Allied World Shareholders.  The manner in which your shares may be voted depends on how your shares are held. If you are a shareholder of record of Allied World, meaning that your Allied World shares are represented by certificates or book entries in your name so that you appear as a shareholder of record in Allied World’s share register maintained by its transfer agent, Continental Stock Transfer & Trust Company, a proxy card for voting these shares will be included with this joint proxy statement/prospectus. You may direct how your shares are to be voted by completing, signing and returning the proxy card in the enclosed envelope. You may also vote your Allied World shares in person at the Allied World Special Shareholder Meeting.
 
If you hold Allied World shares in “street name” through a bank or brokerage firm, you may instead receive from your bank or brokerage firm a voting instruction form with the joint proxy statement/prospectus that you may use to instruct them on how your shares are to be voted. As with a proxy card, you may direct how your shares are to be voted by completing, signing and returning the voting instructions form in the envelope provided. Many banks and brokerage firms have arranged for internet or telephonic voting of shares and provide instructions for using those services on the voting instruction form. If you want to vote your Allied World shares in person at the Allied World Special Shareholder Meeting, you must obtain a proxy from your bank, brokerage firm or other nominee giving you the right to vote your Allied World shares at the Allied World Special Shareholder Meeting.
 
Transatlantic Stockholders.  If you are a stockholder of record of Transatlantic as of the close of business on the Transatlantic record date, you may vote in person by attending the Transatlantic Special Shareholder Meeting or, to ensure your shares are represented at the Transatlantic Special Shareholder Meeting, you may authorize a proxy to vote by:
 
• logging onto           and following the instructions on your proxy card to vote via the internet anytime up to               , on          , 2011 and following the instructions provided on that site;


vi


Table of Contents

 
• dialing           and listening for further directions to vote by telephone anytime up to                on          , 2011 and following the instructions provided in the recorded message; or
 
• signing and returning the accompanying proxy card in the enclosed postage-paid envelope. Transatlantic stockholders of record may submit their proxies through the mail by completing their proxy card, and signing, dating and returning it in the enclosed, pre-addressed, postage-paid envelope. To be valid, a returned proxy card must be signed and dated.
 
If you hold Transatlantic common stock in “street name” through a bank, brokerage firm or other nominee, please follow the voting instructions provided by your bank, brokerage firm or other nominee to ensure that your shares of Transatlantic common stock are represented at the Transatlantic Special Shareholder Meeting. If you want to vote your Transatlantic common stock in person at the Transatlantic Special Shareholder Meeting, you must obtain a proxy from your bank, brokerage firm or other nominee giving you the right to vote your Transatlantic common stock at the Transatlantic Special Shareholder Meeting.
 
Q: How many votes do I have?
 
A: Allied World Shareholders:  Holders of Allied World shares are entitled to one vote per Allied World share owned as of the close of business on the Allied World record date, unless you own “controlled shares” that constitute 10% or more of the issued Allied World shares as of the close of business on the Allied World record date, in which case your voting rights with respect to those controlled shares will be limited, in the aggregate, to a voting power of approximately 10% pursuant to a formula specified in article 14 of the Allied World Articles. The Allied World Articles define controlled shares generally to include all shares of Allied World directly, indirectly or constructively owned or beneficially owned by any person or group of persons. As of the close of business on the Allied World record date, there were           Allied World shares outstanding and entitled to vote at the Allied World Special Shareholder Meeting.
 
Transatlantic Stockholders:  Holders of Transatlantic common stock are entitled to one vote for each share owned as of the close of business on the Transatlantic record date. However, to satisfy the requirements of New York State Insurance regulators, on June 1, 2009, Davis Selected Advisors, L.P. (“Davis Advisors”) entered into a binding agreement with Transatlantic whereby Davis Advisors agreed to vote the number of shares of Transatlantic common stock owned by Davis Advisors in excess of 9.9% of Transatlantic’s outstanding shares in a manner proportionate to the vote of the owners of the shares (excluding Davis Advisors, shareholders beneficially owning more than 10% of Transatlantic’s outstanding shares, and directors and officers of Transatlantic ) voting on such matters. As of the close of business on the Transatlantic record date, there were           shares of Transatlantic common stock outstanding and entitled to vote at the Transatlantic Special Shareholder Meeting.
 
Q: What vote is required to approve each proposal?
 
A: Allied World Shareholders:  Approval of each of the following proposals require the affirmative vote of at least 662/3% of the votes represented at the Allied World Special Shareholder Meeting and a majority of the nominal value of the Allied World shares represented at such meeting, where holders of at least 50% of the total outstanding Allied World shares are represented and voting and who are entitled to vote on such proposal: (i) the article 3 share capital increase proposal, (ii) the article 5 share capital increase proposal and (iii) the article 6 share capital increase proposal. Abstentions will not be considered votes cast and will have no effect on these proposals, assuming a quorum is present.
 
The approval of the NYSE share issuance proposal and the Stock Incentive Plan proposal requires the affirmative vote of the holders of a majority of shares entitled to vote on the proposal and present in person or represented by proxy at the Allied World Special Shareholder Meeting, provided that the total votes cast on this proposal represent over 50% of the outstanding Allied World shares entitled to vote on such proposal. Votes “for,” votes “against” and abstentions count as votes cast. All outstanding Allied World shares count as shares entitled to vote. Thus, the total sum of votes “for,” plus votes “against,” plus abstentions, which we refer to as the “NYSE votes cast,” must be greater than 50% of the total outstanding Allied World shares. The number of votes “for” the proposal must be greater than 50% of the NYSE votes cast.


vii


Table of Contents

 
Approval of each of the following proposals requires a majority of the votes cast voting in favor of such proposal at the Allied World Special Shareholder Meeting where holders of at least 50% of the total outstanding Allied World shares are represented and voting and who are entitled to vote on such proposal: (i) the name change proposal, (ii) the election of directors proposal and (iii) the capital reduction proposal. Abstentions will not be considered votes cast and will have no effect on these proposals, assuming a quorum is present.
 
Because the nature of the proposals to be voted on by the Allied World shareholders at the Allied World Special Shareholder Meeting are all “non-routine” matters, there will be no “broker non-votes” for purposes of the Allied World Special Shareholder Meeting. Accordingly, if a bank or brokerage firm holds your shares you are urged to instruct your bank or brokerage firm on how to vote your shares to ensure your shares are voted on each of the proposals to be brought before the Allied World Special Shareholder Meeting.
 
Transatlantic Stockholders:  The adoption of the merger agreement proposal requires the affirmative vote of the holders of a majority of the outstanding shares of Transatlantic common stock entitled to vote thereon. Failures to vote, votes to abstain and broker non-votes, if any, will have the effect of a vote “AGAINST” the adoption of the merger agreement proposal.
 
Approval of the adjournment proposal requires the affirmative vote of the holders of a majority of the shares of Transatlantic common stock entitled to vote and present in person or represented by proxy, whether or not a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the adjournment proposal. Failures to vote and broker non-votes, if any, will not be voted, but this will not have an effect on the adjournment proposal.
 
Approval of the golden parachute proposal requires the affirmative vote of the holders of a majority of the shares of Transatlantic common stock present in person or represented by proxy and entitled to vote thereon, assuming a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the golden parachute proposal. Failures to vote and broker non-votes, if any, will not be voted, but this will not have an effect on the golden parachute proposal, assuming a quorum is present.
 
Q: My shares are held in “street name” by my bank, brokerage firm or other nominee. Will my bank, brokerage firm or other nominee automatically vote my shares for me?
 
A: No. If your shares are held in the name of a bank, brokerage firm or other nominee, you are considered the “beneficial holder” of the shares held for you in what is known as “street name.” You are not the “record holder” of such shares. If this is the case, this joint proxy statement/prospectus has been forwarded to you by your bank, broker or other nominee. As the beneficial holder, unless your bank, brokerage firm or other nominee has discretionary authority over your shares, you generally have the right to direct your bank, brokerage firm or other nominee as to how to vote your shares. If you do not provide voting instructions, your shares will not be voted on any proposal on which your bank, brokerage firm or other nominee does not have discretionary authority, including certain matters to be considered at the Special Shareholder Meetings. This is often called a “broker non-vote.” You should provide your bank, broker or other nominee with instructions as to how to vote your Allied World shares and Transatlantic common stock, as applicable.
 
Please follow the voting instructions provided by your bank, broker or other nominee so that it may vote your shares on your behalf. Please note that you may not vote shares held in street name by returning a proxy card directly to Allied World or Transatlantic or by voting in person at your meeting unless you first obtain a proxy from your bank, brokerage firm or other nominee.
 
Q: How does the Allied World board of directors recommend that Allied World shareholders vote?
 
A: The Allied World board of directors has unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are advisable and in the best interests of Allied World. The Allied World board of directors unanimously recommends that the Allied World shareholders vote (i) “FOR” the share capital increase proposals, (ii) “FOR” the NYSE share issuance proposal, (iii) “FOR” the name change proposal , (iv) “FOR” the election of directors proposal, (v) “FOR” the capital reduction proposal and (vi) “FOR” the Stock Incentive Plan proposal.

Q: How does the Transatlantic board of directors recommend that Transatlantic stockholders vote?
 
A: The Transatlantic board of directors has unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are advisable and in the best interests of Transatlantic and its stockholders. The Transatlantic board of directors unanimously recommends that Transatlantic stockholders vote (i) “FOR” the adoption of the merger agreement proposal, (ii) “FOR” the adjournment proposal and (iii) “FOR” the golden parachute proposal.
 
Q: What will happen if I return my proxy card without indicating how to vote?
 
A: Allied World Shareholders:  If you properly complete and sign your proxy card but do not indicate how your Allied World shares should be voted on a matter, the Allied World shares represented by your proxy will be voted as the Allied World board of directors recommends and, therefore, “FOR” the proposals brought before the Allied World Special Shareholder Meeting.
 
Transatlantic Stockholders:  If you properly complete and sign your proxy card but do not indicate how your shares of Transatlantic common stock should be voted on a matter, the shares of Transatlantic common stock represented by your proxy will be voted as the Transatlantic board of directors recommends and, therefore, “FOR” the proposals brought before the Transatlantic Special Shareholder Meeting.
 
Q: How do I appoint and vote via the independent proxy if I am an Allied World shareholder of record?
 
A: If you are an Allied World shareholder of record as of the Allied World record date, under Swiss law you may authorize the independent proxy, Mr. Paul Buergi, of Buis Buergi AG, Muehlebachstrasse 7, P.O Box 672, CH-8024, Zurich, Switzerland, with full rights of substitution, to vote your Allied World shares on your behalf instead of using the enclosed proxy card. If you authorize the independent proxy to vote your shares without giving instructions, your shares will be voted in accordance with the recommendations of the Allied World board of directors with regard to the items listed in the notice of meeting. If new agenda items (other than those in the notice of meeting) or new proposals or motions with respect to those agenda items set forth in the notice of meeting are being put forth before the Allied World Special Shareholder Meeting, the independent proxy will, in the absence of other specific instructions, vote in accordance with the recommendations of the Allied World board of directors. An optional form of proxy card that may be used by the independent proxy to vote your Allied World shares is included with this joint proxy statement/prospectus. Proxy cards authorizing the independent proxy to vote your shares must be sent directly to the independent proxy, arriving no later than          , local time,          , 2011.
 
Q: Can I change my vote or revoke my proxy after I have returned a proxy or voting instruction card?
 
A: Yes.
 
If you are the holder of record of Allied World shares:  If you are the holder of record of Allied World shares, you can change your vote or revoke your proxy at any time before your proxy is voted at your meeting. You can do this in one of the following ways:
 
• you can provide the Allied World corporate secretary with written notice of revocation, by voting in person at the Allied World Special Shareholder Meeting or by executing a later-dated proxy card; provided, however, that the action is taken in sufficient time to permit the necessary examination and tabulation of the subsequent proxy or revocation before the vote is taken; or
 
• if you have granted your proxy to the independent proxy, you can provide Mr. Paul Buergi, of Buis Buergi AG, Muehlebachstrasse 7, P.O. Box 672, CH-8024, Zurich, Switzerland, with written notice of revocation, by voting in person at the Allied World Special Shareholder Meeting or by executing a later-dated independent proxy card. Revocation of, or changes to, proxies issued to the independent proxy must be received by the independent proxy by          , local time, on          , 2011.
 
Attendance at the Allied World Special Shareholder Meeting by an Allied World shareholder who has executed and delivered a proxy card to Allied World shall not in and of itself constitute a revocation of such proxy. Only your vote at the Allied World Special Shareholder Meeting will revoke your proxy.

If you hold Allied World shares in “street name”:  If your Allied World shares are held in street name, you must obtain a proxy from your bank, brokerage firm or other nominee giving you the right to vote your Allied World shares at the Allied World Special Shareholder Meeting.
 
If you are the holder of record of Transatlantic common stock:  If you are the holder of record of Transatlantic common stock, you can change your vote or revoke your proxy at any time before your proxy is voted at your meeting. You can do this in one of the following ways:
 
• you can grant a new, valid proxy bearing a later date (including by telephone or via the internet);
 
• you can send a signed notice of revocation; or
 
• you can attend the Transatlantic Special Shareholder Meeting and vote in person, which will automatically cancel any proxy previously given, or you may revoke your proxy in person. Simply attending the Transatlantic Special Shareholder Meeting without voting will not revoke any proxy that you have previously given or change your vote.
 
If you choose either of the first two methods, your notice of revocation or your new proxy must be received by Transatlantic no later than the beginning of the Transatlantic Special Shareholder Meeting. If you have submitted a proxy for your shares by telephone or via the internet, you may revoke your prior telephone or internet proxy by any manner described above.

A: No gain or loss will be recognized by Allied World shareholders as a consequence of the merger.
 
Q: What are the material U.S. federal income tax consequences of the merger to U.S. holders of Transatlantic common stock?

Q: When do you expect the merger to be completed?
 
A: Allied World and Transatlantic hope to complete the merger as soon as reasonably possible and expect the closing of the merger to occur in the fourth quarter of 2011. However, the merger is subject to various regulatory clearances and the satisfaction or waiver of other conditions, and it is possible that factors outside the control of Allied World and Transatlantic could result in the merger being completed at an earlier time, a later time or not at all. There may be a substantial amount of time between the Special Shareholder Meetings and the completion of the merger.

Transatlantic Stockholders:  If you are a Transatlantic stockholder, after the merger is completed, each share of Transatlantic common stock you hold will be converted automatically into the right to receive 0.88 Allied World shares together with cash in lieu of any fractional Allied World shares, as applicable. You will receive instructions at that time regarding exchanging your shares of Transatlantic common stock for Allied World shares. You do not need to take any action at this time. Please do not send your Transatlantic stock certificates with your proxy card.
 
Q: Are holders of shares entitled to appraisal rights?
 
A: No. Neither the Allied World shareholders, under Swiss law, nor the Transatlantic stockholders, under Delaware law, are entitled to appraisal rights in connection with the merger.

Q: What happens if I sell my shares of Transatlantic common stock before the Transatlantic Special Shareholder Meeting?
 
A: The record date for the Transatlantic Special Shareholder Meeting is earlier than the date of the Transatlantic Special Shareholder Meeting and the date that the merger is expected to be completed. If you transfer your shares of Transatlantic common stock after the Transatlantic record date but before the Transatlantic Special Shareholder Meeting, you will retain your right to vote at the Transatlantic Special Shareholder Meeting, but will have transferred the right to receive the merger consideration in the merger. In order to receive the merger consideration, you must hold your shares through the effective date of the merger.
 
Q: What if I hold shares in both Allied World and Transatlantic?
 
A: If you are a holder of shares of both Allied World and Transatlantic you will receive two separate packages of proxy materials. A vote cast as an Allied World shareholder will not count as a vote cast as a Transatlantic stockholder, and a vote cast as a Transatlantic stockholder will not count as a vote cast as an Allied World shareholder. Therefore, please separately submit a proxy for your Allied World shares and your Transatlantic common stock.
 
Q: Who can help answer my questions?
 
A: Allied World shareholders or Transatlantic stockholders who have questions about the merger, the other matters to be voted on at the Special Shareholder Meetings, how to submit a proxy or desire additional copies of this joint proxy statement/prospectus or additional proxy cards should contact:

GO Sub, LLC
 
GO Sub, LLC, a wholly-owned subsidiary of Allied World (“Merger Sub”), is a Delaware limited liability company, which was initially incorporated on June 2, 2011 as a corporation and subsequently converted to a limited liability company on June 10, 2011, and was formed for the sole purpose of effecting the merger. In the merger, Merger Sub will be merged with and into Transatlantic, with Transatlantic surviving as a wholly-owned subsidiary of Allied World.
 
The Merger
 
A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus. Allied World and Transatlantic encourage you to read the entire merger agreement carefully because it is the principal document governing the merger. For more information on the merger agreement, see the section entitled “The Merger Agreement” beginning on page 87.
 
Effects of the Merger (see page 42)
 
Subject to the terms and conditions of the merger agreement, a copy of which is included as Annex A to this joint proxy statement/prospectus, at the effective time of the merger, Merger Sub will be merged with and into Transatlantic, with Transatlantic surviving the merger as a wholly-owned subsidiary of Allied World. Upon completion of the merger, Allied World will be the parent company of Transatlantic, and Allied World’s name will be changed to TransAllied Group Holdings, AG.
 
Merger Consideration (see page 87)
 
Transatlantic stockholders will be entitled to receive 0.88 Allied World shares for each share of Transatlantic common stock they hold at the effective time of the merger (the “exchange ratio”) and cash in lieu of any Allied World fractional shares. The exchange ratio is fixed and will not be adjusted for changes in the market value of Transatlantic common stock or Allied World shares. As a result, the implied value of the consideration to Transatlantic stockholders will fluctuate between the date of this joint proxy statement/prospectus and the effective date of the merger. Based on the closing price of Allied World shares on the NYSE on June 10, 2011, the last trading day before public announcement of the merger, the exchange ratio represented approximately $51.10 in value for each share of Transatlantic common stock. Based on the closing price of Allied World shares on the NYSE on          , 2011, the latest practicable trading day before the date of this joint proxy statement/prospectus, the exchange ratio represented approximately $      in value for each share of Transatlantic common stock.
 
Material U.S. Federal Income Tax Consequences of the Merger (see page 121)
 
The receipt of Allied World shares in exchange for shares of Transatlantic common stock pursuant to the merger will be a taxable transaction for U.S federal income tax purposes. In general, a U.S. holder that receives Allied World shares in exchange for shares of Transatlantic common stock pursuant to the merger will recognize capital gain or loss for U.S federal income tax purposes in an amount equal to the difference, if any, between (i) the sum of the fair market value of the Allied World shares received as of the effective time of the merger and the amount of cash, if any, received in lieu of fractional Allied World shares and (ii) the holder’s adjusted tax basis in the shares of Transatlantic common stock exchanged for the Allied World shares pursuant to the merger. No gain or loss will be recognized by Allied World shareholders. For further information regarding the U.S. federal income tax consequences of the merger, see the section entitled “Material U.S. Federal Income Tax Consequences” beginning on page 121.

Opinion of Allied World’s Financial Advisor (see page 53)
 
Allied World engaged Deutsche Bank Securities Inc. (“Deutsche Bank”) to act as its financial advisor in connection with the merger. At the June 12, 2011 meeting of the Allied World board of directors, Deutsche Bank rendered an oral and written opinion to the board of directors of Allied World to the effect that, based upon and subject to the assumptions, limitations, qualifications and conditions set forth in the opinion, as of the date of such opinion, the exchange ratio was fair, from a financial point of view, to Allied World.
 
The full text of the written opinion of Deutsche Bank, dated June 12, 2011, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations, qualifications and conditions of the review undertaken by Deutsche Bank in connection with the opinion, is included in this joint proxy statement/prospectus as Annex B and is incorporated by reference herein. Allied World shareholders are urged to read Deutsche Bank’s opinion carefully and in its entirety. Deutsche Bank provided its opinion to Allied World’s board of directors in connection with and for the purposes of its evaluation of the transactions contemplated by the merger agreement. Deutsche Bank’s opinion relates only to the fairness, from a financial point of view, of the exchange ratio to Allied World, and does not constitute a recommendation to any holder of Allied World shares as to how any such holder should vote with respect to the proposals to be considered at the Allied World Special Shareholder Meeting or any other matter. In addition, Deutsche Bank was not requested to opine as to, and its opinion does not in any manner address, the merits of Allied World’s underlying business decision to proceed with or effect the merger or the relative merits of the merger as compared to any alternative transactions or business strategies. See also “The Merger — Opinion of Allied World’s Financial Advisor.”
 
Opinion of Transatlantic’s Financial Advisor (see page 68)
 
Moelis & Company LLC (“Moelis”) delivered its oral opinion, which was subsequently confirmed in writing, that based upon and subject to the conditions and limitations set forth in its written opinion, as of June 12, 2011, the exchange ratio set forth in the merger agreement was fair, from a financial point of view, to the holders of Transatlantic common stock.

The full text of the written opinion of Moelis, dated June 12, 2011, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with its opinion, is attached to this joint proxy statement/prospectus as Annex C. The summary of Moelis’ opinion contained in this joint proxy statement/prospectus describes the material analyses underlying Moelis’ opinion, but does not purport to be a complete description of the analyses performed by Moelis in connection with its opinion, and is qualified in its entirety by reference to the full text of the opinion. Moelis provided its opinion for the information and assistance of the Transatlantic board of directors in connection with its consideration of the merger. Moelis’ opinion is limited solely to the fairness, from a financial point of view, of the exchange ratio set forth in the merger agreement to the holders of Transatlantic common stock as of the date of the opinion and does not constitute a recommendation to any holder of Transatlantic common stock as to how such Transatlantic stockholder should vote with respect to the merger or any other matter. In addition, Moelis was not requested to opine as to, and its opinion does not in any manner address, Transatlantic’s underlying business decision to effect the merger or the relative merits of the merger as compared to any alternative business strategies or transactions that might be available to Transatlantic. See also “The Merger — Opinion of Transatlantic’s Financial Advisor.”
 
Interests of Allied World’s Directors and Executive Officers in the Merger (see page 78)
 
Executive officers and members of the Allied World board of directors have interests in the merger that may be different from, or in addition to, the interests of Allied World shareholders generally.
 
As described in further detail below under the heading “The Merger — Board of Directors and Management Following the Merger,” certain of Allied World’s executive officers and members of the Allied World board of directors will continue to serve as officers or directors of the combined company upon completion of the merger. Specifically, Mr. Scott A. Carmilani will serve as the President and Chief Executive Officer of the combined company unless he is not the Chief Executive Officer of Allied World immediately prior to the effective time of the merger.
 
Each of Allied World’s executive officers is a party to an employment agreement that would provide for the acceleration of certain payments and benefits upon the consummation of the merger. Allied World is in the process of implementing a new retention program pursuant to which certain of its executive officers would waive all or a portion of the accelerated payments and benefits in exchange for the new retention arrangement.
 
The Allied World board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement and the transactions contemplated by the merger agreement and in recommending that you vote to approve the share capital increase proposals, the NYSE share issuance proposal, the name change proposal, the election of directors proposal, the capital reduction proposal and the Stock Incentive Plan proposal.
 
Interests of Transatlantic’s Directors and Executive Officers in the Merger (see page 78)
 
Executive officers and members of the Transatlantic board of directors have interests in the merger that may be different from, or in addition to, the interests of Transatlantic stockholders generally.
 
Additionally, as detailed below under “The Merger — Board of Directors and Management Following the Merger,” certain of Transatlantic’s executive officers and members of the Transatlantic board of directors will continue to serve as officers or directors of the combined company upon completion of the merger. Specifically, Mr. Richard S. Press, the current non-executive chairman of the Transatlantic board of directors, will be the non-executive chairman of the board of directors of the combined company and Mr. Michael C. Sapnar, the current Executive Vice President and Chief Operating Officer of Transatlantic, will be appointed to serve as President and Chief Executive Officer of Global Reinsurance of the combined company.
 
While Transatlantic has various compensation and benefits arrangements that provide for “double trigger” payments (i.e., payments upon certain termination events in proximity to a “change in control”), the merger will not constitute a “change in control” for purposes of such arrangements. However, Transatlantic has entered into certain retention agreements with certain executives, providing for the grant of restricted stock

units (or in the event that there are not enough share reserves, phantom stock awards) if the employment of such executives is maintained through December 31, 2013 (or in certain instances of termination prior to that date).
 
In general, outstanding options to acquire Transatlantic common stock and compensatory stock awards denominated in shares of Transatlantic common stock will be converted into options to acquire TransAllied shares and compensatory stock awards denominated in TransAllied shares. The equity holdings of Transatlantic’s directors and executive officers will be treated in the same manner as the equity holdings of all other equity holders. For additional information regarding the interests of Transatlantic directors and executive officers in the merger, please see the section entitled “The Merger — Interests of Transatlantic’s Directors and Executive Officers in the Merger” on page 78.
 
The Transatlantic board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement and in recommending that you vote for the adoption of the merger agreement proposal, the adjournment proposal and the golden parachute proposal.
 
Board of Directors and Management Following the Merger (see page 81)
 
Immediately following the effective time of the merger, assuming the receipt of the resignation letters of all current directors of Allied World and of shareholder approval of the election of directors proposal as described herein, the board of directors of the combined company will consist of 11 members including (i) four independent Transatlantic directors, (ii) Richard S. Press (the current non-executive chairman of the Transatlantic board of directors), (iii) Michael C. Sapnar (the current Executive Vice President and Chief Operating Officer of Transatlantic), (iv) four independent Allied World directors and (v) Scott A. Carmilani (the current Chairman, President and Chief Executive Officer of Allied World). The 11 members of the board of directors of the combined company will be divided into three classes of directors as follows:
 
  •  Class II (to hold office commencing upon the completion of the merger and ending upon TransAllied’s Annual Shareholder Meeting in 2012) consisting of two former independent Transatlantic directors and a former independent Allied World director;
 
  •  Class III (to hold office commencing upon the completion of the merger and ending upon TransAllied’s Annual Shareholder Meeting in 2013) consisting of two former independent Transatlantic directors and two former independent Allied World directors; and
 
  •  Class I (to hold office commencing upon the completion of the merger and ending upon TransAllied’s Annual Shareholder Meeting in 2014): Scott A. Carmilani, Richard S. Press, Michael C. Sapnar and a former independent Allied World director.
 
Immediately following the effective time of the merger, Mr. Carmilani will serve as President and Chief Executive Officer of the combined company. Mr. Press will be elected as non-executive chairman of the board of directors of the combined company (the “TransAllied board”). Effective on the first anniversary of the closing date of the merger, Mr. Press will cease to serve as non-executive chairman and shall remain on the TransAllied board as a director until the second anniversary of the closing date of the merger, at which time he has agreed to retire from the TransAllied board (subject to his earlier resignation or retirement). Mr. Sapnar will be appointed to serve as President and Chief Executive Officer of Global Reinsurance of the combined company.
 
The foregoing director elections and officer appointments are conditioned upon completion of the merger. In the event that the merger is not completed, the foregoing director elections and officer appointments will not take effect.
 
The appointments of Messrs. Carmilani, Press and Sapnar, among other matters, will be reflected in the amended and restated organizational regulations of TransAllied (the “TransAllied organizational regulations”), which will take effect only upon completion of the merger, and, for a period of one year following the closing date, any resolution to revise, modify or delete such provisions will require a majority of at least eight of the votes cast by the TransAllied board.

Treatment of Transatlantic Stock Options and Other Stock-Based Awards and Programs (see page 84)
 
Prior to the effective time of the merger, the Allied World board of directors (or, if appropriate, the committee thereof administering the Allied World stock plans) will adopt resolutions or take other actions as may be required to effect the below actions with respect to the Transatlantic stock options and stock-based awards.
 
Stock Options.  Upon completion of the merger, each outstanding option to purchase shares of Transatlantic common stock will be converted pursuant to the merger agreement into a stock option to purchase Allied World shares on the same terms and conditions as were in effect immediately prior to the completion of the merger based on the exchange ratio.
 
Stock-Based Awards.  Upon completion of the merger, each outstanding stock-based award of Transatlantic will be converted into Allied World shares or other compensatory awards denominated in Allied World shares subject to a risk of forfeiture to, or the right to repurchase by, Allied World, with the same terms and conditions as were applicable under such Transatlantic stock-based awards, and each holder of Transatlantic stock-based awards shall be entitled to receive a number of converted Transatlantic stock-based awards equal to the product of the number of Transatlantic stock-based awards held by such holder and the exchange ratio.
 
Allied World and Transatlantic are engaged in discussions relating to the adjustment of performance goals of all Allied World and Transatlantic stock-based awards that vest based on the achievement of performance criteria in order to appropriately reflect the merger with respect to performance based periods that have not ended prior to the merger.
 
Regulatory Clearances Required for the Merger (see page 82)
 
Allied World and Transatlantic have each agreed to take actions in order to obtain regulatory clearances required to consummate the merger. Regulatory clearances include expiration or termination of the required waiting period under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, and the rules and regulations promulgated thereunder (the “HSR Act”), following required notifications and review by the Antitrust Division of the U.S. Department of Justice (the “Antitrust Division”) or the Federal Trade Commission (the “FTC”). The parties filed the required notifications with the Antitrust Division and the FTC on July 1, 2011.
 
In addition to those filings required by the HSR Act, certain insurance regulatory filings will also be required to consummate the merger. State insurance laws in the United States generally require that, prior to the acquisition of an insurance company, the acquiring party must obtain approval from the insurance commissioner of the insurance company’s state of domicile, and the parties have and will make the required filings in accordance with such laws. In addition, applications or notifications have been or will be filed with various insurance regulatory authorities outside of the United States in connection with the changes in control that may be deemed to occur as a result of the transactions contemplated by the merger agreement.
 
Allied World and Transatlantic also expect to file notices with insurance regulators and antitrust and competition authorities in certain other jurisdictions. While Allied World and Transatlantic expect to obtain all required regulatory clearances, we cannot assure you that these regulatory clearances will be obtained or that the granting of these regulatory clearances will not involve the imposition of additional conditions on the completion of the merger, including the requirement to divest assets, or require changes to the terms of the merger agreement. These conditions or changes could result in the conditions to the merger not being satisfied.
 
Amended and Restated Articles of Association of Allied World (see page 106)
 
The Allied World board of directors proposes to the Allied World shareholders, subject to completion of the merger, to amend the Allied World Articles to change Allied World’s name to “TransAllied Group Holdings, AG”. The form of the Articles of Association of TransAllied (the “TransAllied Articles”) is included in this joint proxy statement/prospectus as Annex D. The adoption of the TransAllied Articles by the Allied

Table of Contents

World shareholders is a condition to completion of the merger. In the event this proposal is approved by Allied World shareholders, but the merger is not completed, the TransAllied Articles will not become effective.
 
Expected Timing of the Merger
 
Allied World and Transatlantic currently expect the closing of the merger to occur in the fourth quarter of 2011. However, the merger is subject to various regulatory clearances and the satisfaction or waiver of other conditions as described in the merger agreement, and it is possible that factors outside the control of Allied World and Transatlantic could result in the merger being completed at an earlier time, a later time or not at all.
 
Conditions to Completion of the Merger (see page 98)
 
The obligations of Allied World and Transatlantic to complete the merger are subject to the satisfaction of the following conditions:
 
  •  approval by the Allied World shareholders of (i) the share capital increase proposals, (ii) the NYSE share issuance proposal and (iii) the name change proposal;
 
  •  approval by the Transatlantic stockholders of the adoption of the merger agreement proposal;
 
  •  authorization of the listing of the Allied World shares to be issued in the merger on the NYSE, subject to official notice of issuance;
 
  •  the waiting period (and any extension thereof) applicable to the merger under the HSR Act having expired or been earlier terminated;
 
  •  obtaining any necessary approvals of the applicable insurance regulatory authorities in New York, Bermuda and Switzerland;
 
  •  receipt of other requisite regulatory approvals;
 
  •  all consents and approvals of, and filings with, governmental agencies having been made, obtained and in full force, other than those that would not reasonably be expected to have a material adverse effect on Allied World and Transatlantic after giving effect to the merger;
 
  •  effectiveness of the registration statement of which this joint proxy statement/prospectus forms a part and the absence of a stop order or proceedings threatened or initiated by the SEC for that purpose;
 
  •  absence of any order, injunction, decree, statute, rule or regulation by a court or other governmental entity that makes illegal or prohibits the completion of the merger or the other transactions contemplated by the merger agreement;
 
  •  approval by the Allied World shareholders of the election of directors proposal and execution of a written consent of the TransAllied board approving certain committee and officer appointments;
 
  •  a ruling from the Swiss Commercial Register having been obtained; and
 
  •  the purchase by Allied World, following receipt of the requisite Allied World and Transatlantic shareholder approvals, of 45,000 shares of Transatlantic common stock having been completed.
 
In addition, each of Allied World’s and Transatlantic’s obligations to effect the merger is subject to the satisfaction or waiver of the following additional conditions:
 
  •  the representations and warranties of each party, other than the representations related to the shares issued and outstanding or reserved for issuance, the necessary corporate power and authority to execute and deliver the merger agreement, and the brokers’ and finders’ fees, will be true and correct (without giving effect to any materiality qualifications contained in such representations and warranties) as of the date of the merger agreement and as of the closing date (other than those representations and warranties that were made only as of a specified date, which need only be true and correct as of such specified date), except where the failure of such representations and warranties to be so true and correct

Table of Contents

  (without giving effect to any limitation as to “materiality” or to material adverse effect set forth therein), individually or in the aggregate, has not had, and would not reasonably be expected to have, a material adverse effect on such party;
 
  •  the representations and warranties of each party relating to the shares issued and outstanding or reserved for issuance, the necessary corporate power and authority to execute and deliver the merger agreement, and the brokers and finders’ fees, will be true and correct in all material respects as of the date of the merger agreement and as of the closing date (except to the extent such representations or warranties were made as of an earlier date, in which case, as of such earlier date);
 
  •  each party having performed or complied with, in all material respects, all its obligations under the merger agreement at or prior to the effective time of the merger; and
 
  •  receipt of a certificate executed by each party’s chief executive officer or chief financial officer as to the satisfaction of the conditions described in the preceding three bullet points.
 
See the section entitled “The Merger Agreement — Conditions to Completion of the Merger” for a further discussion of the conditions to closing of the merger.
 
No Solicitation of Alternative Proposals (see page 92)
 
The merger agreement precludes Allied World and Transatlantic from soliciting or engaging in discussions or negotiations with a third party with respect to a proposal for a competing transaction, including the acquisition of a significant interest in Allied World’s or Transatlantic’s common stock or assets. However, if Allied World or Transatlantic receives an unsolicited proposal from a third party for a competing transaction that Allied World’s or Transatlantic’s board of directors, as applicable, among other things, determines in good faith (after consultation with its outside legal advisors and financial advisors) (i) is reasonably likely to lead to a proposal that is superior to the merger and (ii) the failure to enter discussions regarding such proposal would result in a breach of its fiduciary obligations under applicable law, Allied World or Transatlantic, as applicable, may, subject to certain conditions, furnish non-public information to and enter into discussions with, and only with, that third party regarding such competing transaction.
 
See the section entitled “The Merger Agreement — No Solicitation of Alternative Proposals” for a further discussion of each party’s covenant not to solicit alternative acquisition proposals.
 
Termination of the Merger Agreement (see page 99)
 
Generally, the merger agreement may be terminated and the merger may be abandoned at any time prior to the completion of the merger (except as specified below, including after the required Allied World shareholder approvals or Transatlantic stockholder approvals are obtained):
 
  •  by mutual written consent of Allied World and Transatlantic; or

See the section entitled “The Merger Agreement — Termination of the Merger Agreement” for a further discussion of the rights of each of Allied World and Transatlantic to terminate the merger agreement.
 
Expenses and Termination Fees; Liability for Breach (see page 99)
 
Generally, all fees and expenses incurred in connection with the merger agreement and the transactions contemplated by the merger agreement will be paid by the party incurring those expenses, subject to the specific exceptions discussed in this joint proxy statement/prospectus whereby Allied World or Transatlantic, as the case may be, may be required to pay a termination fee of $115 million or $35 million and/or the reimbursement of expenses up to a maximum amount of $35 million.
 
See the section entitled “The Merger Agreement — Expenses and Termination Fees; Liability for Breach” for a further discussion of the circumstances under which such termination fees and/or expense reimbursement will be required to be paid.
 
Accounting Treatment (see page 123)
 
Allied World and Transatlantic each prepare its financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and any statutory accounting principles prescribed or permitted by the domiciliary state insurance department of the applicable subsidiary (“SAP”). The merger will be accounted for using the acquisition method of accounting. Transatlantic will be the accounting acquirer.
 
See the section entitled “Accounting Treatment” for a further discussion of the accounting treatment of the transaction.
 
No Appraisal Rights (see page 85)
 
Neither the holders of Allied World shares, under Swiss law, nor the holders of shares of Transatlantic common stock, under Delaware law, are entitled to appraisal rights in connection with the merger.
 
See the section entitled “The Merger — No Appraisal Rights” for a further discussion of the appraisal rights in connection with the merger.
 
Comparison of Stockholder Rights and Corporate Governance Matters (see page 146)
 
Transatlantic stockholders, whose rights are currently governed by the Transatlantic restated certificate of incorporation (the “Transatlantic charter”), the Transatlantic amended and restated by-laws (the “Transatlantic bylaws”) and Delaware law, will, upon completion of the merger, become shareholders of the combined company and their rights will be governed by the TransAllied Articles, the TransAllied organizational regulations and Swiss law. As a result, Transatlantic stockholders will have different rights once they become shareholders of the combined company due to differences between the governing documents of Transatlantic and TransAllied, and differences between Delaware and Swiss law. These differences are described in detail under the section entitled “Comparison of Rights of TransAllied Shareholders and Transatlantic Stockholders.”
 
Listing of Allied World Shares; De-listing and Deregistration of Shares of Transatlantic Common Stock (see page 85)
 
It is a condition to the completion of the merger that the Allied World shares to be issued to Transatlantic stockholders pursuant to the merger be authorized for listing on the NYSE at the effective time of the merger. Upon completion of the merger, shares of Transatlantic common stock currently listed on the NYSE will cease to be listed on the NYSE and will subsequently be deregistered under the Exchange Act.

Summary Unaudited Pro Forma Condensed Consolidated
Financial Information of Allied World and Transatlantic
 
The following table presents selected unaudited pro forma condensed consolidated financial information about the combined company’s consolidated balance sheet and statements of operations, after giving effect to the merger. The information under “Selected Pro Forma Condensed Consolidated Statements of Operations Data” in the table below gives effect to the merger as if it had been consummated on January 1, 2010, the beginning of the earliest period presented. The information under “Selected Pro Forma Condensed Consolidated Balance Sheet Data” in the table below assumes the merger had been consummated on March 31, 2011. This unaudited pro forma condensed consolidated financial information was prepared using the acquisition method of accounting, with Transatlantic considered the accounting acquirer of Allied World. See “Accounting Treatment” on page 123.
 
In addition, the selected unaudited pro forma condensed consolidated financial information includes adjustments that are preliminary and may be revised. There can be no assurance that such revisions will not result in material changes. The selected unaudited pro forma condensed consolidated financial information is presented for illustrative purposes only and is not necessarily indicative of results that actually would have occurred or that may occur in the future had the merger been completed on the dates indicated, nor is it necessarily indicative of the future operating results or financial position of the combined company.
 
The information presented below should be read in conjunction with the historical consolidated financial statements of Allied World and Transatlantic including the related notes, filed by each of them with the SEC, and with the pro forma condensed consolidated financial information of Allied World and Transatlantic, including the related notes, appearing elsewhere in this document.

Unaudited Comparative Per Share Data
 
Presented below are Allied World’s and Transatlantic’s historical per share data for the three months ended March 31, 2011 and the year ended December 31, 2010 and unaudited pro forma consolidated per share data for the three months ended March 31, 2011 and the year ended December 31, 2010. This information should be read together with the consolidated financial statements and related notes of Allied World and Transatlantic that are incorporated by reference in this joint proxy statement/prospectus and with the unaudited pro forma condensed consolidated financial data included under “Unaudited Pro Forma Condensed Consolidated Financial Information” beginning on page 124. The pro forma information is presented for illustrative purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the merger had been completed as of the beginning of the periods presented, nor is it necessarily indicative of the future operating results or financial position of the combined company. The historical book value per share is computed by dividing total stockholders’ equity by the number of shares of common stock outstanding at the end of the period. The pro forma net income (loss) per share of the combined company is computed by dividing the pro forma net income (loss) by the pro forma weighted average number of shares outstanding. The pro forma book value per share of the combined company is computed by dividing total pro forma stockholders’ equity by the pro forma number of shares of common stock outstanding at the end of the period. The Transatlantic unaudited pro forma equivalent per share financial information is computed by multiplying the Allied World unaudited pro forma consolidated per share amounts by the exchange ratio (0.88 Allied World shares for each share of Transatlantic common stock).

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
This joint proxy statement/prospectus and the documents incorporated by reference into this joint proxy statement/prospectus contain forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 that are not limited to historical facts, but reflect Allied World’s and Transatlantic’s current beliefs, expectations or intentions regarding future events. These statements include in general forward-looking statements both with respect to Allied World and Transatlantic and the insurance and reinsurance industry. Statements that are not historical facts, including statements that use terms such as “anticipates,” “believes,” “expects,” “intends,” “plans,” “projects,” “seeks” and “will” and that relate to our plans and objectives for future operations, are forward-looking statements. In light of the risks and uncertainties inherent in all forward-looking statements, the inclusion of such statements in this joint proxy statement/prospectus should not be considered as a representation by us or any other person that our objectives or plans will be achieved. These forward-looking statements include, without limitation, Allied World’s and Transatlantic’s expectations with respect to the synergies, costs and other anticipated financial impacts of the proposed transaction; future financial and operating results of the combined company; the combined company’s plans, objectives, expectations and intentions with respect to future operations and services; approval of the proposed transaction by stockholders and by governmental regulatory authorities; the satisfaction of the closing conditions to the proposed transaction; and the timing of the completion of the proposed transaction.
 
All forward-looking statements involve significant risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements, many of which are generally outside the control of Allied World and Transatlantic and are difficult to predict. These risks and uncertainties also include those set forth under “Risk Factors,” beginning on page 22, as well as, among others, risks and uncertainties relating to: any event, change or other circumstance that could give rise to the termination of the merger agreement; the inability to obtain Transatlantic’s or Allied World’s shareholder approval or the failure to satisfy other conditions to completion of the merger, including receipt of regulatory approvals; risks that the proposed transaction disrupts each company’s current plans and operations; the ability to retain key personnel; the ability to realize the benefits of the merger; the amount of the costs, fees, expenses and charges related to the merger; pricing and policy term trends; increased competition; the impact of acts of terrorism and acts of war; greater frequency or severity of unpredictable catastrophic events; negative rating agency actions; the adequacy of each party’s loss reserves; Allied World or its non-U.S. subsidiaries becoming subject to significant income taxes in the United States or elsewhere; changes in regulations or tax laws; changes in the availability, cost or quality of reinsurance or retrocessional coverage; adverse general economic conditions; and judicial, legislative, political and other governmental developments, as well as management’s response to these factors, and other factors identified in each company’s filings with the SEC. Allied World and Transatlantic caution that the foregoing list of factors is not exclusive.
 
Additional information concerning these and other risk factors is contained in Allied World’s and Transatlantic’s most recently filed Annual Reports on Form 10-K, subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and other SEC filings. All subsequent written and oral forward-looking statements concerning Allied World, Transatlantic, the proposed transaction or other matters and attributable to Allied World or Transatlantic or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. You are cautioned not to place undue reliance on these forward-looking statements, which speak only to the date they are made. Allied World and Transatlantic are under no obligation (and expressly disclaim any such obligation) to update or revise any forward-looking statement that may be made from time to time, whether as a result of new information, future developments or otherwise.

RISK FACTORS
 
In addition to the other information included and incorporated by reference in this joint proxy statement/prospectus, including the matters addressed in the section entitled “Special Note Regarding Forward-Looking Statements,” you should carefully consider the following risks before deciding whether to vote for the adoption of the merger agreement proposal, the adjournment proposal and the golden parachute proposal, in the case of Transatlantic stockholders, or for the share capital increase proposals, the NYSE share issuance proposal, the name change proposal, the election of directors proposal, the capital reduction proposal and the Stock Incentive Plan proposal, in the case of Allied World shareholders. In addition, you should read and consider the risks associated with each of the businesses of Allied World and Transatlantic because these risks will also affect the combined company. These risks can be found in the Annual Reports on Form 10-K for the fiscal year ended December 31, 2010 for each of Allied World and Transatlantic, as such risks may be updated or supplemented in each company’s subsequently filed Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, which are incorporated by reference into this joint proxy statement/prospectus. You should also read and consider the other information in this joint proxy statement/prospectus and the other documents incorporated by reference in this joint proxy statement/prospectus. See the section entitled “Where You Can Find More Information” beginning on page 159.
 
Risk Factors Relating to the Merger
 
The exchange ratio is fixed and will not be adjusted in the event of any change in either Allied World’s or Transatlantic’s stock price.
 
Upon closing of the merger, each share of Transatlantic common stock will be converted into the right to receive 0.88 Allied World shares. This exchange ratio is fixed in the merger agreement and will not be adjusted for changes in the market price of either Allied World shares or Transatlantic common stock between the date of signing the merger agreement and completion of the merger. Changes in the price of Allied World shares prior to the completion of the merger will affect the market value of Allied World shares that Transatlantic stockholders will receive on the effective date of the merger. Stock price changes may result from a variety of factors (many of which are beyond Allied World’s or Transatlantic’s control), including the following factors:
 
  •  changes in Allied World’s and Transatlantic’s respective businesses, operations and prospects, or the market assessments thereof;
 
  •  market assessments of the likelihood that the merger will be completed, including related considerations regarding regulatory approvals of the merger; and
 
  •  general market and economic conditions and other factors generally affecting the price of Allied World shares and Transatlantic common stock.
 
The price of Allied World shares at the closing of the merger may vary from the price on the date the merger agreement was executed, on the date of this joint proxy statement/prospectus and on the date of the Special Shareholder Meetings of Allied World and Transatlantic. As a result, the market value represented by the exchange ratio will also vary. For example, based on the range of closing prices of Allied World shares during the period from June 10, 2011, the last trading date before public announcement of the merger, through          , 2011, the last practicable trading date before the date of this joint proxy statement/prospectus, the exchange ratio represented a market value ranging from a low of $      to a high of $      for each share of Transatlantic common stock.
 
Because the merger will be completed after the Special Shareholder Meetings, at the time of your Special Shareholder Meeting, you will not know the exact market value of the Allied World shares that Transatlantic stockholders will receive upon completion of the merger.
 
If the price of Allied World shares increases between the time of the meetings and the effective time of the merger, Transatlantic stockholders will receive Allied World shares that have a market value that is greater than the market value of such shares at the time of the meetings. If the price of Allied World shares decreases


22


Table of Contents

between the time of the meetings and the effective time of the merger, Transatlantic stockholders will receive Allied World shares that have a market value that is less than the market value of such shares at the time of the meetings. Therefore, because the exchange ratio is fixed, stockholders cannot be sure at the time of the meetings of the market value of the consideration that will be paid to Transatlantic stockholders upon completion of the merger.
 
The merger is subject to a number of conditions, including certain governmental and regulatory conditions that may not be satisfied, or may not be completed on a timely basis, or at all. Failure to complete the transactions could have material and adverse effects on Allied World and Transatlantic.
 
Completion of the merger is conditioned upon, among other matters, the receipt of certain governmental authorizations, consents, orders or other approvals, including the expiration or termination of the waiting period under the HSR Act, the approval of antitrust authorities in the United Kingdom and Germany, and the approval of insurance regulators in Bermuda, Switzerland and New York. In deciding whether to grant antitrust, insurance or other regulatory clearances, the relevant governmental entities will consider the effect of the merger within their relevant jurisdictions. The governmental agencies from which Allied World and Transatlantic will seek the approvals have broad discretion in administering the governing regulations. The terms and conditions of the approvals that are granted may impose requirements, limitations or costs or place restrictions on the conduct of the combined company’s business. There can be no assurance that regulators will not impose conditions, terms, obligations or restrictions and that such conditions, terms, obligations or restrictions will not have the effect of delaying completion of the merger or imposing additional material costs on, or materially limiting the revenues of, the combined company following the merger. In addition, neither Allied World nor Transatlantic can provide assurances that any such conditions, terms, obligations or restrictions will not result in the delay or abandonment of the merger. For a more detailed description of the regulatory review process, see the section entitled “The Merger — Regulatory Clearances Required for the Merger” beginning on page 82.
 
If the merger is not completed on a timely basis, or at all, Allied World’s and Transatlantic’s respective ongoing businesses may be adversely affected. Additionally, in the event the merger is not completed, Allied World and Transatlantic will be subject to a number of risks without realizing any of the benefits of having completed the merger, including (i) the payment of certain fees and costs relating to the merger, such as legal, accounting, financial advisor and printing fees, (ii) the potential decline in the market price of Allied World’s and Transatlantic’s shares, (iii) the risk that the parties may not find a party willing to enter into a merger agreement on terms equivalent to or more attractive than the terms set forth in the merger agreement and (iv) the loss of time and resources.
 
Uncertainties associated with the merger may cause a loss of management personnel and other key employees which could adversely affect the future business, operations and financial results of the combined company.
 
Whether or not the merger is completed, the announcement and pendency of the merger could disrupt the businesses of Allied World and Transatlantic. Allied World and Transatlantic are dependent on the experience and industry knowledge of their senior management and other key employees to execute their business plans. The combined company’s success after the merger will depend in part upon the ability of Allied World and Transatlantic to retain key management personnel and other key employees. Current and prospective employees of Allied World and Transatlantic may experience uncertainty about their roles within the combined company following the merger, which may have an adverse effect on the ability of each of Allied World and Transatlantic to attract or retain key management and other key personnel. Accordingly, no assurance can be given that the combined company will be able to attract or retain key management personnel and other key employees of Allied World and Transatlantic to the same extent that such companies have previously been able to attract or retain employees. In addition, the combined company might not be able to locate suitable replacements for any such key employees who leave the combined company or offer employment to potential replacements on reasonable terms.

Several lawsuits have been filed against Allied World and Transatlantic challenging the merger, and an adverse ruling may prevent the merger from being completed.
 
Allied World and Transatlantic, as well as the members of the Transatlantic board of directors, have been named as defendants in several lawsuits brought by purported shareholders of Transatlantic challenging the merger and seeking, among other things, injunctive relief to enjoin the defendants from completing the merger on the agreed-upon terms. See “The Merger — Litigation Related to the Merger” beginning on page 85 for more information about the lawsuits that have been filed related to the merger.
 
One of the conditions to the closing of the merger is that no order, injunction, decree or other legal restraint or prohibition shall be in effect that prevents completion of the merger. Consequently, if a settlement or other resolution is not reached in the lawsuits referenced above and the plaintiffs secure injunctive or other relief prohibiting, delaying or otherwise adversely affecting Allied World and Transatlantic’s ability to complete the merger, then such injunctive or other relief may prevent the merger from becoming effective within the expected timeframe or at all.
 
The merger agreement contains provisions that could discourage a potential competing acquiror of either Allied World or Transatlantic.
 
The merger agreement contains “no shop” provisions that, subject to limited exceptions, restrict each of Allied World’s and Transatlantic’s ability to solicit, initiate, or knowingly encourage and facilitate competing third-party proposals for the acquisition of its company’s shares or assets. Further, even if the Allied World board of directors or the Transatlantic board of directors, respectively, withdraws or qualifies its recommendation with respect to the merger, Allied World or Transatlantic, as the case may be, will still be required to submit each of their merger-related proposals to a vote at their shareholder meeting. In addition, the other party generally has an opportunity to offer to modify the terms of the merger in response to any competing acquisition proposals before the board of directors of the company that has received a third-party proposal may withdraw or qualify its recommendation with respect to the merger. In some circumstances, upon termination of the merger agreement, one of the parties will be required to pay a termination fee of $115 million or $35 million to the other party, and/or an expense reimbursement up to a maximum of $35 million. See “The Merger Agreement — No Solicitation of Alternative Proposals” beginning on page 92, “The Merger Agreement — Termination of the Merger Agreement” beginning on page 99 and “The Merger Agreement — Expenses and Termination Fees; Liability for Breach” beginning on page 99.
 
These provisions could discourage a potential third-party acquiror that might have an interest in acquiring all or a significant portion of Allied World or Transatlantic from considering or proposing that acquisition, at a higher per share cash or market value than the market value proposed to be received or realized in the merger or might result in a potential third-party acquiror proposing to pay a lower price to the shareholders than it might otherwise have proposed to pay because of the added expense of the termination fee and/or expense reimbursement that may become payable in certain circumstances.
 
If the merger agreement is terminated and either Allied World or Transatlantic determines to seek another business combination, it may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the merger.
 
The fairness opinions delivered by Deutsche Bank and Moelis will not reflect changes in circumstances between signing the merger agreement and the completion of the merger.
 
Neither the Allied World board of directors nor the Transatlantic board of directors has obtained an updated fairness opinion as of the date of this joint proxy statement/prospectus from Deutsche Bank, Allied World’s financial advisor, or Moelis, Transatlantic’s financial advisor.
 
Changes in the operations and prospects of Allied World or Transatlantic, general market and economic conditions and other factors that may be beyond their control, and on which the fairness opinions were based, may alter the value of Allied World or Transatlantic or the prices of Allied World shares or Transatlantic common stock by the time the merger is completed. The opinions do not speak as of the time the merger will


24


Table of Contents

be completed or as of any date other than the dates of such opinions. Because neither company anticipates asking its financial advisor to update its opinion, these opinions only address the fairness of the exchange ratio or merger consideration, from a financial point of view, at the time the merger agreement was executed. The opinions are included as Annexes B and C to this joint proxy statement/prospectus. For a description of the opinions and a summary of the material financial analyses in connection with rendering such opinions, please refer to “The Merger — Opinion of Allied World’s Financial Advisors” beginning on page 53 and “The Merger — Opinion of Transatlantic’s Financial Advisor” beginning on page 68.
 
The merger will be taxable to Transatlantic stockholders.
 
The receipt of Allied World shares (and cash, if any, received in lieu of Allied World fractional shares) by U.S. holders in exchange for shares of Transatlantic common stock pursuant to the merger will be a taxable transaction for U.S. federal income tax purposes. For a description of the tax consequences of the merger, please refer to “Material U.S. Federal Income Tax Consequences” beginning on page 121.
 
Risk Factors Relating to the Combined Company Following the Merger
 
Although Allied World and Transatlantic expect to realize certain benefits as a result of the merger, there is the possibility that the combined company may be unable to integrate successfully the businesses of Allied World and Transatlantic in order to realize the anticipated benefits of the merger.
 
The merger involves the combination of two companies that currently operate as independent public companies. The combined company will be required to devote significant management attention and resources to integrating the business practices and operations of Allied World and Transatlantic. Due to legal restrictions, Allied World and Transatlantic have been able to conduct only limited planning regarding the integration of the two companies after completion of the merger and have not yet determined the exact nature of how the businesses and operations of the two companies will be combined thereafter. Potential difficulties the combined company may encounter as part of the integration process include the following:
 
  •  the inability to successfully combine the businesses in a manner that permits the combined company to achieve the full synergies anticipated to result from the merger;
 
  •  complexities associated with managing the combined businesses, including the challenge of integrating complex systems, technology, networks and other assets of each company in a seamless manner that minimizes any adverse impact on customers, suppliers, brokers, employees and other constituencies;
 
  •  the costs of integration and compliance and the possibility that the full benefits anticipated to result from the merger will not be realized;
 
  •  any delay in the integration of management teams, strategies, operations, products and services;
 
  •  diversion of the attention of each company’s management as a result of the merger;
 
  •  differences in business backgrounds, corporate cultures and management philosophies that may delay successful integration;
 
  •  the ability to retain key employees;
 
  •  the ability to create and enforce uniform standards, controls, procedures, policies and information systems;
 
  •  potential unknown liabilities and unforeseen increased expenses or delays associated with the merger, including one-time cash costs to integrate the companies beyond current estimates; and
 
  •  the disruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies,
 
any of which could adversely affect each company’s ability to maintain relationships with customers, suppliers, brokers, employees and other constituencies or Allied World’s and Transatlantic’s ability to achieve the


25


Table of Contents

anticipated benefits of the merger or could reduce each company’s earnings or otherwise adversely affect the business and financial results of the combined company.
 
Current Allied World shareholders and Transatlantic stockholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management.
 
Current Allied World shareholders have the right to vote in the election of the Allied World board of directors and on other matters affecting Allied World. Current Transatlantic stockholders have the right to vote in the election of the Transatlantic board of directors and on other matters affecting Transatlantic. Immediately after the merger is completed, it is expected that, on a fully diluted basis, current Allied World shareholders will own approximately 42% of the combined company and current Transatlantic stockholders will own approximately 58% of the combined company. As a result of the merger, current Allied World shareholders and current Transatlantic stockholders will have less influence on the management and policies of the combined company than they now have on the management and policies of Allied World and Transatlantic, respectively. Additionally, the Allied World Articles impose voting restrictions on holders of 10% or more of the total combined voting power of Allied World issued shares such that these shareholders’ voting power is reduced to less than 10% of the total voting power.
 
The future results of the combined company will suffer if the combined company does not effectively manage its expanded operations following the merger.
 
Following the merger, the size of the business of the combined company will increase significantly beyond the current size of either Allied World’s or Transatlantic’s business. The combined company’s future success depends, in part, upon its ability to manage this expanded business, which will pose substantial challenges for management, including challenges related to the management and monitoring of new global operations and associated increased costs and complexity. There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements and other benefits currently anticipated from the merger.
 
The financial analyses and forecasts considered by Allied World and Transatlantic and their respective financial advisors may not be realized, which may adversely affect the market price of Allied World shares following the merger.
 
In performing their financial analyses and rendering their opinions regarding the fairness, from a financial point of view, of the exchange ratio set forth in the merger agreement, each of the respective financial advisors to Allied World and Transatlantic independently reviewed and relied on, among other things, internal stand-alone and pro forma financial analyses and forecasts as separately provided to each respective financial advisor by Allied World or Transatlantic. See the sections entitled “The Merger— Certain Allied World Prospective Financial Information” and “The Merger — Certain Transatlantic Prospective Financial Information.” The financial advisor of Transatlantic, Moelis, assumed, at the direction of the board of directors of Transatlantic, that such financial information was reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Allied World and Transatlantic as to the future performance of their respective companies and that such future financial results will be achieved at the times and in the amounts projected by management of Allied World and Transatlantic. These analyses and forecasts were prepared by, or as directed by, the managements of Allied World and Transatlantic and were also considered by the Allied World board of directors and the Transatlantic board of directors. None of these analyses or forecasts were prepared with a view towards public disclosure or compliance with the published guidelines of the SEC, GAAP, SAP, international financial reporting standards (“IFRS”) or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts. These projections are inherently based on various estimates and assumptions that are subject to the judgment of those preparing them. These projections are also subject to significant economic, competitive, industry and other uncertainties and contingencies, all of which are difficult or impossible to predict and many of which are beyond the control of Allied World and Transatlantic. Accordingly, there can be no assurance that Allied World’s or Transatlantic’s financial condition or results of operations will be consistent with those set forth in


26


Table of Contents

such analyses and forecasts. Significantly worse financial results could have a material adverse effect on the market price of TransAllied shares following the merger.
 
The combined company is expected to incur substantial expenses related to the merger and the integration of the companies.
 
The combined company is expected to incur substantial expenses in connection with the merger and the integration of Allied World and Transatlantic. There are a large number of processes, policies, procedures, operations, technologies and systems that must be integrated. While Allied World and Transatlantic have assumed that a certain level of expenses would be incurred, there are many factors beyond their control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the savings that the combined company expects to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings. These integration expenses likely will result in the combined company taking significant charges against earnings following the completion of the merger, and the amount and timing of such charges are uncertain at present.
 
There can be no assurance that the merger will not result in a ratings downgrade of Allied World’s or Transatlantic’s insurance or reinsurance operating companies, which may result in an adverse effect on the business, financial condition and operating results.
 
Ratings with respect to claims paying ability and financial strength are important factors in establishing the competitive position of insurance and reinsurance companies and will also impact the cost and availability of capital to an insurance and reinsurance holding company. The combined operations of Allied World and Transatlantic will compete with other insurance and reinsurance companies, financial intermediaries and financial institutions on the basis of a number of factors, including the ratings assigned by internationally-recognized rating organizations. Ratings will represent an important consideration in maintaining customer confidence in the combined company and in its ability to market insurance and reinsurance products. Rating organizations regularly analyze the financial performance and condition of insurers. Any ratings downgrade, or the potential for a ratings downgrade, of Allied World, Transatlantic, the combined company or any of their insurance or reinsurance subsidiaries could adversely affect their ability to market and distribute products and services, which could have an adverse effect on Allied World’s, Transatlantic’s or the combined company’s, as applicable, business, financial condition and operating results. There is a risk that Allied World and/or Transatlantic is subject to being downgraded, and there can be no assurance that the ratings of the combined company’s insurance and reinsurance operating companies will not be downgraded, following the merger.
 
Ratings are not in any way a measure of protection afforded to investors and should not be relied upon in making an investment or voting decision.
 
The occurrence of severe catastrophic events may cause the combined company’s financial results to be volatile and may affect the financial results of the combined company differently than such an event would have affected the financial results of either Allied World or Transatlantic on a stand-alone basis.
 
Because the combined company will, among other things, underwrite property catastrophe insurance and reinsurance and have large aggregate exposures to natural and man-made disasters, management expects that the combined company’s loss experience generally will include infrequent events of great severity. Consequently, the occurrence of losses from catastrophic events is likely to cause substantial volatility in the combined company’s financial results. In addition, because catastrophes are an inherent risk of the combined company’s business, a major event or series of events can be expected to occur from time to time and to have a material adverse effect on the combined company’s financial condition and results of operations, possibly to the extent of eliminating the combined company’s shareholders’ equity. Upon completion of the merger, the combined company’s exposure to natural and man-made disasters will be different from the exposure of either Allied World or Transatlantic prior to the completion of the merger. Accordingly, the merger may exacerbate the exposure described above.

Table of Contents

Some of the executive officers and directors of Allied World and Transatlantic have interests in seeing the merger completed that are different from, or in addition to, those of the other Allied World and Transatlantic stockholders. Therefore, some of the executive officers and directors of Allied World may have a conflict of interest in recommending the proposals being voted on at the Allied World Special Shareholder Meeting and some of the executive officers and directors of Transatlantic may have a conflict of interest in recommending the proposals being voted on at the Transatlantic Special Shareholder Meeting.
 
Certain of the executive officers of Allied World and Transatlantic have arrangements that provide them with interests in the merger that are different from, or in addition to, those of stockholders of Allied World and Transatlantic generally. These interests include, among others, ownership interests in the combined company, continued service as an executive officer of the combined company, payments and equity grants, and the accelerated vesting of certain equity awards and/or certain severance benefits, in connection with the merger. These interests may influence the executive officers of Allied World to support or approve the proposals to be presented at the Allied World Special Shareholder Meeting and/or the executive officers of Transatlantic to support or approve the proposals to be presented at the Transatlantic Special Shareholder Meeting.
 
In addition, certain directors of Allied World and Transatlantic may have interests in the merger that are different from, or in addition to, those of stockholders of Allied World and Transatlantic generally, including ownership interests and equity grants in the combined company and continued service as a director of the combined company. These interests may influence the directors of Allied World and Transatlantic to support or approve the proposals to be presented at the Allied World Special Shareholder Meeting and/or the Transatlantic Special Shareholder Meeting.
 
See “The Merger — Interests of Allied World’s Directors and Executive Officers in the Merger” beginning on page 78 and “The Merger — Interests of Transatlantic’s Directors and Executive Officers in the Merger” beginning on page 78 for a more detailed description of these interests.
 
The Allied World shares to be received by Transatlantic stockholders as a result of the merger will have different rights from the shares of Transatlantic common stock.
 
Upon completion of the merger, Transatlantic stockholders will become shareholders of TransAllied, and their rights as shareholders will be governed by the TransAllied Articles, the TransAllied organizational resolutions and Swiss law. The rights associated with Transatlantic common stock are different from the rights associated with Allied World shares. See “Comparison of Rights of TransAllied Shareholders and Transatlantic Stockholders” beginning on page 146.
 
Other Risk Factors of Allied World and Transatlantic
 
Allied World’s and Transatlantic’s businesses are and will be subject to the risks described above. In addition, Allied World and Transatlantic are, and will continue to be, subject to the risks described in Allied World’s and Transatlantic’s Annual Reports on Form 10-K for the fiscal year ended December 31, 2010, as updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all of which are filed with the SEC and incorporated by reference into this joint proxy statement/prospectus.

Recommendations of the Board of Directors of Allied World
 
The Allied World board of directors unanimously approved the merger agreement and the amendment to the Allied World Articles and determined that the merger agreement and the transactions contemplated thereby, including the merger, the issuance of the Allied World shares to Transatlantic stockholders pursuant to the merger and the adoption of the amendment to the Allied World Articles, are in the best interests of Allied World.
 
The Allied World board of directors unanimously recommends that the Allied World shareholders vote “FOR” each of the proposals set forth above. See the section entitled “The Merger — Allied World’s Reasons for the Merger; Recommendations of the Allied World Board of Directors” beginning on page 51 for a more detailed discussion of the Allied World board of directors’ recommendation.
 
Allied World Record Date; Shareholders Entitled to Vote
 
Only Allied World shareholders of record at the close of business on          , 2011, the Allied World record date, are entitled to notice of, and to vote at, the Allied World Special Shareholder Meeting.
 
At the close of business on the Allied World record date, there were           Allied World shares issued and outstanding and entitled to vote at the Allied World Special Shareholder Meeting. Holders of Allied World shares will have one vote for each Allied World share they owned on the Allied World record date, in person or by a properly executed and delivered proxy with respect to the Allied World Special Shareholder Meeting, unless such shareholders own “controlled shares” that constitute 10% or more of the issued Allied World shares, in which case the voting rights with respect to those “controlled shares” will be limited, in the aggregate, to a voting power of approximately 10% pursuant to a formula specified in article 14 of the Allied World Articles. The Allied World Articles define “controlled shares” generally to include all shares of Allied World directly, indirectly or constructively owned or beneficially owned by any person or group of persons. The share capital of Allied World consists of the outstanding Allied World shares and Allied World non-voting shares.
 
Voting by Allied World’s Directors and Executive Officers
 
At the close of business on the Allied World record date, directors and executive officers of Allied World and their affiliates were entitled to vote            Allied World shares, or approximately     % of the Allied World shares outstanding on that date. We currently expect that Allied World’s directors and executive officers will vote their shares in favor of each of the proposals to be considered and voted upon at the Special Shareholder Meeting, although none of them has entered into any agreement obligating them to do so.
 
Quorum
 
In order to transact business at the Allied World Special Shareholder Meeting, a quorum is required. Two or more persons present in person and representing in person or by proxy throughout the meeting more than 50% of the total issued and outstanding Allied World shares registered in Allied World’s share register constitute a quorum for the transaction of business at the Allied World Special Shareholder Meeting. The Allied World board of directors or chairman of the Allied World board of directors may postpone the meeting with sufficient factual reason, provided that notice of postponement is given to the shareholders in the same form as the invitation before the time for such meeting. A new notice is then required to hold the postponed meeting. Under Swiss law, a general meeting of shareholders for which a notice of meeting has been duly published may not be adjourned without publishing a new notice of meeting.
 
Abstentions (Allied World shares for which proxies have been received but for which the holders have abstained from voting) will be counted toward the presence of a quorum at the Allied World Special Shareholder Meeting. While “broker non-votes” would generally be counted for purposes of establishing a quorum for the Allied World Special Shareholder Meeting, because the nature of the proposals to be voted on by the Allied World shareholders at the Allied World Special Shareholder Meeting are all “non-routine”


31


Table of Contents

matters for which your broker does not have discretionary voting authority, there will be no “broker non-votes” for purposes of the Allied World Special Shareholder Meeting.
 
Required Vote; Failures to Vote, Abstentions, Broker Non-Votes
 
Approval of each of the following proposals requires the affirmative vote of at least 662/3 of the votes represented at the Allied World Special Shareholder Meeting and a majority of the nominal value of the Allied World shares represented at such meeting, where holders of at least 50% of the total outstanding Allied World shares are represented and voting and who are entitled to vote on such proposal: (i) the article 3 share capital increase proposal, (ii) the article 5 share capital increase proposal and (iii) the article 6 share capital increase proposal. Abstentions will not be considered votes cast and will have no effect on these proposals, assuming a quorum is present.
 
The approval of the NYSE share issuance proposal and the Stock Incentive Plan proposal requires the affirmative vote of the holders of a majority of shares entitled to vote on the proposal and present in person or represented by proxy at the Allied World Special Shareholder Meeting, provided that the total votes cast on this proposal represent over 50% of the outstanding Allied World shares entitled to vote on this proposal; provided further that the approval of the NYSE share issuance proposal is conditioned upon the approval of the share capital increase proposal, as provided above. Votes “for,” votes “against” and abstentions count as votes cast. All outstanding Allied World shares count as shares entitled to vote. Thus, the total sum of votes “for,” plus votes “against,” plus abstentions, which we refer to as the “NYSE votes cast”, must be greater than 50% of the total outstanding Allied World shares. The number of votes “for” the proposal must be greater than 50% of the NYSE votes cast.
 
Each of the following approvals requires a majority of the votes cast voting in favor of such proposal at the Allied World Special Shareholder Meeting where holders of at least 50% of the total outstanding Allied World shares are represented and voting and who are entitled to vote on such proposal: (i) the name change proposal, (ii) the election of directors proposal and (iii) the capital reduction proposal. Abstentions will not be considered votes cast and will have no effect on these proposals, assuming a quorum is present.
 
Because the nature of the proposals to be voted on by the Allied World shareholders at the Allied World Special Shareholder Meeting are all “non-routine” matters, there will be no “broker non-votes” for purposes of the Allied World Special Shareholder Meeting. Accordingly, if a broker or bank holds your shares you are urged to instruct your broker or brokerage firm on how to vote your shares to ensure your shares are voted on each of the proposals to be brought before the Allied World Special Shareholder Meeting.
 
Completion of the merger is conditioned on, among other things, approval of the share capital increase proposals, the NYSE share issuance proposal, the name change proposal and the election of directors proposal.
 
Voting of Proxies by Holders of Record
 
If you are a holder of record of Allied World shares, a proxy card is enclosed for your use. Allied World requests that you submit a proxy by signing the accompanying proxy and returning it promptly in the enclosed postage-paid envelope. When the accompanying proxy is returned properly executed, the Allied World shares represented by it will be voted at the Allied World Special Shareholder Meeting or any adjournment or postponement thereof in accordance with the instructions contained in the proxy.
 
If a proxy is returned without an indication as to how the Allied World shares represented are to be voted with regard to a particular proposal, the Allied World shares represented by the proxy will be voted in accordance with the recommendation of the Allied World board of directors and, therefore, “FOR” each of the proposals to be considered and voted upon at such meeting. As of the date hereof, management has no knowledge of any business that will be presented for consideration at the Allied World Special Shareholder Meeting and that would be required to be set forth in this joint proxy statement/prospectus or the related proxy card other than the matters set forth in Allied World’s Notice of Special Shareholder Meeting. If any other matter is properly presented at the Allied World Special Shareholder Meeting for consideration, it is intended


32


Table of Contents

that the persons named in the enclosed form of proxy and acting thereunder will vote in accordance with their best judgment on such matter.
 
Voting by Independent Proxy
 
If you are an Allied World shareholder of record as of the Allied World record date, under Swiss law you may authorize the independent proxy, Mr. Paul Buergi, of Buis Buergi AG, Muehlebachstrasse 7, P.O. Box 672, CH-8024, Zurich, Switzerland, with full rights of substitution, to vote your Allied World shares on your behalf instead of using the enclosed proxy card. If you authorize the independent proxy to vote your shares without giving instructions, your shares will be voted in accordance with the recommendations of the Allied World board of directors with regard to the items listed in the notice of meeting. If new agenda items (other than those in the notice of meeting) or new proposals or motions with respect to those agenda items set forth in the notice of meeting are being put forth before the Allied World Special Shareholder Meeting, the independent proxy will, in the absence of other specific instructions, vote in accordance with the recommendations of the Allied World board of directors. An optional form of proxy card that may be used by the independent proxy to vote your Allied World shares is included with this joint proxy statement/prospectus. Proxy cards authorizing the independent proxy to vote your shares must be sent directly to the independent proxy, arriving no later than          , local time,          , 2011.
 
Your vote is important. Accordingly, please sign, date and return the enclosed proxy card whether or not you plan to attend the Allied World Special Shareholder Meeting in person.
 
Shares Held in Street Name
 
If you hold your Allied World shares in a stock brokerage account or if your shares are held by a bank or other nominee (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank, brokerage firm or other nominee. Please note that you may not vote Allied World shares held in street name by returning a proxy card directly to Allied World or by voting in person at the Allied World Special Shareholder Meeting unless you have a “legal proxy,” which you must obtain from your bank, brokerage firm or other nominee. Further, brokers who hold Allied World shares on behalf of their customers may not give a proxy to Allied World to vote those Allied World shares without specific instructions from their customers.
 
If you are an Allied World shareholder and you do not instruct your bank, brokerage firm or other nominee on how to vote your shares your bank, brokerage firm or other nominee, as applicable, may not vote your Allied World shares on any of the proposals to be considered and voted upon at the Allied World Special Shareholder Meeting as all such matters are deemed “non-routine” matters. See “Admission to the Special Shareholder Meeting” below for further information regarding voting your shares that are held in “street name.”
 
Revocation of Proxies
 
If you are the record holder of Allied World shares, you can change your vote or revoke your proxy at any time before your proxy is voted at the Allied World Special Shareholder Meeting. You can do this by:
 
  •  timely delivering a new, valid proxy by mail as described on the proxy card; or
 
  •  attending the Allied World Special Shareholder Meeting and voting in person, which will automatically cancel any proxy previously given, or you can revoke your proxy in person. Simply attending the Allied World Special Shareholder Meeting without voting will not revoke any proxy that you have previously given or change your vote.
 
A registered Allied World shareholder may revoke a proxy by any of these methods, regardless of the method used to deliver the shareholder’s previous proxy.
 
Please note that if your shares are held in “street name” through a bank, brokerage firm or other nominee, you may change your vote by submitting new voting instructions to your bank, brokerage firm or other nominee in accordance with its established procedures. If your Allied World shares are held in the name of a

bank, brokerage firm or other nominee and you decide to change your vote by attending the Allied World Special Shareholder Meeting and voting in person, your vote in person at the Allied World Special Shareholder Meeting will not be effective unless you have obtained and present an executed proxy issued in your name from the record holder (your bank, brokerage firm or other nominee).
 
Tabulation of Votes
 
A representative from Baker & McKenzie Zurich will act as the inspector of elections and will be responsible for tabulating the votes cast by proxy (which will have been certified by Allied World’s independent transfer agent) or in person at the Allied World Special Shareholder Meeting. Under Swiss law, Allied World is responsible for determining whether or not a quorum is present and the final voting results.
 
Solicitation of Proxies
 
Allied World is soliciting proxies for the Allied World Special Shareholder Meeting. In accordance with the merger agreement, Allied World and Transatlantic will share equally all fees and expenses in relation to the printing, filing and distribution of this joint proxy statement/prospectus. Allied World will pay all of its other costs of soliciting proxies. In addition to solicitation by use of mails, proxies may be solicited by Allied World directors, officers and employees in person or by telephone or other means of communication. These individuals will not be additionally compensated, but may be reimbursed for out-of-pocket expenses associated with this solicitation.
 
Allied World has engaged MacKenzie Partners, Inc. (“MacKenzie Partners”) to assist in the solicitation of proxies for the Allied World Special Shareholder Meeting. Allied World estimates that it will pay MacKenzie Partners a fee of approximately $15,000. Allied World will also reimburse MacKenzie Partners for reasonable out-of-pocket expenses and will indemnify MacKenzie Partners and its affiliates against certain claims, liabilities, losses, damages and expenses. Allied World will make arrangements with brokerage houses, custodians, nominees and fiduciaries to forward proxy solicitation materials to beneficial owners of shares held of record by them. Allied World will also reimburse these brokerage houses, custodians, nominees and fiduciaries for their reasonable expenses incurred in forwarding the proxy materials.
 
Adjournments
 
The Allied World board of directors or chairman of the Allied World board of directors may postpone the Allied World Special Shareholder Meeting with sufficient factual reason, provided that notice of postponement is given to the shareholders in the same form as the invitation before the time for such meeting. A new notice is then required to hold the postponed meeting. Under Swiss law, a general meeting of shareholders for which a notice of meeting has been duly published may not be adjourned without publishing a new notice of meeting.

This joint proxy statement/prospectus provides stockholders of Transatlantic with the information they need to know to be able to vote or instruct their vote to be cast at the Transatlantic Special Shareholder Meeting.
 
Date, Time and Place
 
The Transatlantic Special Shareholder Meeting is scheduled to be held at the          on          , 2011 at [8:00 a.m.] local time.
 
Purpose of the Transatlantic Special Shareholder Meeting
 
At the Transatlantic Special Shareholder Meeting, Transatlantic stockholders will be asked to consider and vote on:
 
  •  the proposal to adopt the merger agreement, which is further described in the sections entitled “The Merger” and “The Merger Agreement,” beginning on pages 42 and 87, respectively;
 
  •  the proposal to adjourn the Transatlantic Special Shareholder Meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes to approve the foregoing proposal; and
 
  •  the proposal, on an advisory basis (non-binding), to approve the compensation that may be paid or become payable to Transatlantic’s named executive officers in connection with the merger, and the agreements and understandings pursuant to which such compensation may be paid or become payable, as described below in the section entitled “— Advisory Vote on the Golden Parachute Compensation Arrangements for Transatlantic’s Named Executive Officers.”
 
Completion of the merger is conditioned on, among other things, approval of the adoption of the merger agreement proposal.
 
Advisory Vote on the Golden Parachute Compensation Arrangements for Transatlantic’s Named Executive Officers
 
Recently adopted Section 14A of the Exchange Act requires that Transatlantic provide its stockholders with the opportunity to vote to approve, on an advisory (non-binding) basis, the “golden parachute” compensation arrangements for Transatlantic’s named executive officers, as disclosed in the section entitled “The Merger — Interests of Transatlantic Directors and Executive Officers in the Merger — Golden Parachute Compensation” beginning on page 80.
 
In accordance with Section 14A of the Exchange Act, in this proposal Transatlantic stockholders are being asked to approve the following non-binding resolution at the Transatlantic Special Shareholder Meeting:
 
“RESOLVED, that the stockholders of Transatlantic approve, on an advisory (non-binding) basis, the compensation to be paid by Transatlantic to Transatlantic’s named executive officers that is based on or otherwise relates to the merger with Allied World, as disclosed in the Golden Parachute Compensation Table and related notes and narrative disclosure in the section of the joint proxy statement/prospectus for the Merger entitled “The Merger — Interests of Transatlantic’s Directors and Executive Officers in the Merger — Golden Parachute Compensation.”
 
Approval of this proposal is not a condition to completion of the merger, and the vote with respect to this proposal is advisory only. Accordingly, the vote will not be binding on Transatlantic or Allied World, or the board of directors or the compensation committee of Transatlantic or Allied World.

Recommendations of the Board of Directors of Transatlantic
 
The Transatlantic board of directors has unanimously approved the merger agreement and has determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and in the best interests of Transatlantic and its stockholders.
 
The Transatlantic board of directors unanimously recommends that Transatlantic stockholders vote “FOR” each of the proposals set forth above. See the section entitled “The Merger — Transatlantic’s Reasons for the Merger; Recommendations of the Transatlantic Board of Directors” beginning on page 64 for a more detailed discussion of the Transatlantic board of directors’ recommendation.
 
Transatlantic Record Date; Stockholders Entitled to Vote
 
Only holders of record of Transatlantic common stock at the close of business on           , 2011, the Transatlantic record date, will be entitled to notice of, and to vote at, the Transatlantic Special Shareholder Meeting or any adjournments or postponements thereof.
 
At the close of business on the Transatlantic record date,           shares of Transatlantic common stock were issued and outstanding and held by           holders of record. Holders of record of Transatlantic common stock on the Transatlantic record date are entitled to one vote per share at the Transatlantic Special Shareholder Meeting on each proposal. However, to satisfy the requirements of New York State Insurance regulators, on June 1, 2009, Davis Advisors entered into a binding agreement with Transatlantic whereby Davis Advisors agreed to vote the number of shares of Transatlantic common stock owned by Davis Advisors in excess of 9.9% of Transatlantic’s outstanding shares in a manner proportionate to the vote of the owners of the shares (excluding Davis Advisors, stockholders beneficially owning more than 10% of Transatlantic’s outstanding shares, and directors and officers of Transatlantic ) voting on such matters. A list of stockholders of Transatlantic will be available for review for any purpose germane to the Transatlantic Special Shareholder Meeting at Transatlantic’s headquarters, at 80 Pine Street, New York, New York, during regular business hours for a period of 10 days before the Transatlantic Special Shareholder Meeting. The list will also be available at the Transatlantic Special Shareholder Meeting during the whole time thereof for examination by any stockholder of record present at the Transatlantic Special Shareholder Meeting.
 
Voting by Transatlantic’s Directors and Executive Officers
 
At the close of business on the Transatlantic record date, directors and executive officers of Transatlantic and their affiliates were entitled to vote          shares of Transatlantic common stock, or approximately     % of the shares of Transatlantic common stock outstanding on that date. We currently expect that Transatlantic’s directors and executive officers will vote their shares in favor of each of the proposals to be considered and voted upon at the Transatlantic Special Shareholder Meeting, although none of them has entered into any agreement obligating them to do so.
 
Quorum
 
No business may be transacted at the Transatlantic Special Shareholder Meeting unless a quorum is present. Attendance in person or by proxy at the Transatlantic Special Shareholder Meeting of holders of record of a majority of the aggregate voting power of the outstanding shares of Transatlantic common stock entitled to vote at the meeting will constitute a quorum. If a quorum is not present, or if fewer shares of Transatlantic common stock are voted in favor of the proposal to adopt the merger agreement than the number required for its adoption, the Transatlantic Special Shareholder Meeting may be adjourned to allow additional time for obtaining additional proxies or votes. At any subsequent reconvening of the Transatlantic Special Shareholder Meeting, all proxies will be voted in the same manner as they would have been voted at the original convening of the Transatlantic Special Shareholder Meeting, except for any proxies that have been effectively revoked or withdrawn prior to the subsequent meeting.
 
Abstentions (shares of Transatlantic common stock for which proxies have been received but for which the holders have abstained from voting) will be included in the calculation of the number of shares of


37


Table of Contents

Transatlantic common stock represented at the Transatlantic Special Shareholder Meeting for purposes of determining whether a quorum has been achieved. However, broker non-votes will not be included in the calculation of the number of shares of Transatlantic common stock represented at the Transatlantic Special Shareholder Meeting for purposes of determining whether a quorum has been achieved.
 
Required Vote
 
The approval of the adoption of the merger agreement proposal requires the affirmative vote of the holders of a majority of the outstanding shares of Transatlantic common stock entitled to vote thereon. Failures to vote, votes to abstain and broker non-votes, if any, will have the effect of a vote “AGAINST” the proposal.
 
The approval of the adjournment proposal requires the affirmative vote of the holders of a majority of the shares of Transatlantic common stock entitled to vote and present in person or by proxy, whether or not a quorum is present. The Transatlantic stockholders may so adjourn the Transatlantic Special Shareholder Meeting to another time or place without further notice unless the adjournment is for more than 30 days or if after the adjournment a new record date is fixed for the adjourned meeting, in which case a notice of the adjourned meeting shall be given to each Transatlantic stockholder of record entitled to vote at the meeting. Abstaining will have the same effect as a vote “AGAINST” the proposal. Failures to vote and broker non-votes, if any, will not be voted, but this will not have an effect on the adjournment proposal.
 
The approval of the golden parachute proposal requires the affirmative vote of the holders of a majority of the shares of Transatlantic common stock present in person or represented by proxy and entitled to vote thereon, assuming a quorum is present. Abstentions will have the effect of a vote “AGAINST” the proposal. Failures to vote and broker non-votes, if any, will not be voted, but this will not have an effect on the proposal, assuming a quorum is present.
 
Failures to Vote, Broker Non-Votes and Abstentions
 
Under the rules of the NYSE, banks, brokerage firm or other nominees holding shares of record may vote those shares in their discretion on certain routine proposals when they do not receive timely voting instructions from the beneficial holders. A “broker non-vote” occurs under these NYSE rules when a bank, brokerage firm or other nominee holding shares of record is not permitted to vote on a non-routine matter without instructions from the beneficial owner of the shares and no instruction is given.
 
In accordance with these NYSE rules, banks, brokers and other nominees who hold shares of Transatlantic common stock in “street name” for their customers, but do not have discretionary authority to vote the shares, may not exercise their voting discretion with respect to the adoption of the merger agreement proposal, the adjournment proposal or the golden parachute proposal. Accordingly, if banks, brokers or other nominees do not receive specific voting instructions from the beneficial owner of such shares, they may not vote such shares with respect to the adoption of the merger agreement proposal, the adjournment proposal or the golden parachute proposal. For shares of Transatlantic common stock held in “street name,” only shares of Transatlantic common stock affirmatively voted “FOR” the adoption of the merger agreement proposal, the adjournment proposal and the golden parachute proposal will be counted as affirmative votes therefor.
 
Abstentions, failures to vote and broker non-votes, if any, will have the same effect as a vote “AGAINST” the adoption of the merger agreement proposal. Abstentions will have the same effect as a vote “AGAINST” the adjournment proposal. Failures to vote and broker non-votes, if any, will have no effect on the approval of the adjournment proposal. Abstentions will have the same effect as a vote “AGAINST” the golden parachute proposal. Failures to vote and broker non-votes, if any, will not be voted, but this will not have an effect on the golden parachute proposal, assuming a quorum is present.

If you hold your shares of Transatlantic common stock in a stock brokerage account or if your shares are held by a bank or other nominee (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank, brokerage firm or other nominee. Please note that you may not vote shares of Transatlantic common stock held in street name by returning a proxy card directly to Transatlantic or by voting in person at the Transatlantic Special Shareholder Meeting unless you have a “legal proxy,” which you must obtain from your bank, brokerage firm or other nominee. Further, brokers who hold shares of Transatlantic common stock on behalf of their customers may not give a proxy to Transatlantic to vote those shares without specific instructions from their customers.
 
If you are a Transatlantic stockholder and you do not instruct your bank, brokerage firm or other nominee on how to vote your shares your bank, brokerage firm broker or other nominee, as applicable, may not vote your shares on any of the proposals to be considered and voted upon at the Transatlantic Special Shareholder Meeting as all such matters are deemed “non-routine” matters pursuant to applicable NYSE rules.
 
How Proxies Are Counted
 
All shares of Transatlantic common stock represented by properly executed proxies received in time for the Transatlantic Special Shareholder Meeting will be voted at the meeting in the manner specified by the

Table of Contents

stockholders giving those proxies. Properly executed proxies that do not contain voting instructions will be voted “FOR” the adoption of the merger agreement proposal, the adjournment proposal and the golden parachute proposal.
 
Only shares of Transatlantic common stock affirmatively voted for the applicable proposal, and properly executed proxies that do not contain voting instructions, will be counted as favorable votes for adoption of the merger agreement proposal, the adjournment proposal and the golden parachute proposal. Abstentions, failures to vote and broker non-votes, if any, will have the same effect as votes “AGAINST” the adoption of the merger agreement proposal. Abstentions will have the same effect as a vote “AGAINST” the adjournment proposal. Failures to vote and broker non-votes, if any, will have no effect on the approval of the adjournment proposal. Abstentions will have the same effect as a vote “AGAINST” the golden parachute proposal. Failures to vote and broker non-votes, if any, will not be voted, but this will not have an effect on the golden parachute proposal, assuming a quorum is present.
 
Revocation of Proxies
 
If you are the record holder of shares of Transatlantic common stock, you can change your vote or revoke your proxy at any time before your proxy is voted at the Transatlantic Special Shareholder Meeting. You can do this by:
 
  •  timely delivering a new, valid proxy bearing a later date by submitting instructions via the internet, by telephone or by mail as described on the proxy card;
 
  •  timely delivering a signed written notice of revocation to the Secretary of Transatlantic; or
 
  •  attending the Transatlantic Special Shareholder Meeting and voting in person, which will automatically cancel any proxy previously given, or you can revoke your proxy in person.

A registered Transatlantic stockholder may revoke a proxy by any of these methods, regardless of the method used to deliver the Transatlantic stockholder’s previous proxy.
 
Written notices of revocation and other communications with respect to the revocation of proxies should be addressed as follows:

In accordance with the merger agreement, Transatlantic and Allied World will share equally all fees and expenses in relation to the printing, filing and distribution of this joint proxy statement/prospectus. Transatlantic will pay all of its other costs of soliciting proxies.

THE MERGER
 
Effects of the Merger
 
At the effective time of the merger, Merger Sub, a wholly-owned subsidiary of Allied World that was formed for the sole purpose of effecting the merger, will merge with and into Transatlantic. Transatlantic will survive the merger and become a wholly-owned subsidiary of Allied World. Upon completion of the merger, Allied World will be the parent company of Transatlantic, and Allied World’s name will be changed to TransAllied Group Holdings, AG.
 
In the merger, each outstanding share of Transatlantic common stock (other than shares owned by Transatlantic, Allied World or Merger Sub, which shares will be cancelled) will be converted into the right to receive 0.88 Allied World shares, together with cash paid in lieu of fractional shares. This exchange ratio is fixed and will not be adjusted to reflect share price changes prior to the closing of the merger. Allied World shareholders will continue to hold their existing Allied World shares.
 
Background of the Merger
 
Background of the Merger
 
From 1990, when Transatlantic became a public company, until June 2009, American International Group, Inc. (together with its subsidiaries, “AIG”) owned a controlling interest in Transatlantic’s outstanding common stock. In the second half of 2008, AIG experienced an unprecedented strain on its liquidity. This strain led to a series of transactions with the Federal Reserve Bank of New York and the U.S. Department of the Treasury. On September 29, 2008, AIG, which then owned approximately 59% of Transatlantic’s outstanding common stock, filed an amendment to its Schedule 13D relating to Transatlantic stating, among other things, that “AIG is exploring all strategic alternatives in connection with the potential disposition or other monetization of its . . . interest in [Transatlantic].” A special committee of directors of Transatlantic that were independent of management and of AIG (the “Special Committee”) comprised of Messrs. Richard S. Press, Ian H. Chippendale and John G. Foos was subsequently formed to evaluate proposals received from AIG relating to the possible disposition of, or other transactions involving, AIG’s ownership interest in Transatlantic as well as any related business combination transactions involving Transatlantic’s outstanding shares. Although several parties initially indicated possible interest in a transaction involving Transatlantic’s outstanding shares, these initial indications did not proceed past preliminary proposals, execution of confidentiality and standstill agreements and exchanges of non-public information. On June 10, 2009, AIG disposed of 29,900,000 of its shares of Transatlantic’s common stock in a secondary public offering, reducing its ownership in Transatlantic from approximately 59% to approximately 14%. Subsequently, AIG disposed of its remaining 8,500,000 shares of Transatlantic common stock in a secondary public offering (in which Transatlantic repurchased 2,000,000 of such shares) on March 15, 2010.
 
The board of directors and management of Allied World regularly review and evaluate potential strategic transactions, including business combinations, as part of their ongoing oversight and management of Allied World’s business and in furtherance of Allied World’s goal to increase its competitive positioning within the market. In the years leading up to the present transaction, Allied World, with the assistance of its respective legal and financial advisors, reviewed and analyzed potential strategic transactions with several companies within the insurance and reinsurance industry, but ultimately determined that a transaction with such companies at the relevant times was not strategically optimal. During this time, Allied World also engaged in a review of potential opportunities for smaller acquisitions as well as organic growth, and executed on certain of these initiatives. In October 2008, Allied World acquired Darwin Professional Underwriters, Inc., a specialty U.S. casualty insurer focused on small account primary and healthcare business, to expand Allied World’s U.S. insurance platform. As part of the strategy to grow its U.S. insurance and reinsurance platforms, Allied World also made investments in 2008 and 2009 to hire additional underwriting teams and support staff and build out its infrastructure. In 2010, Allied World established a syndicate at Lloyd’s of London to further expand its underwriting activities.

Table of Contents

Since AIG’s June 2009 secondary offering, the Transatlantic board of directors and senior management have regularly reviewed and assessed strategic alternatives available to enhance stockholder value, including possible business combination transactions. In February 2010, Transatlantic selected Moelis to act as its financial advisor in connection with a review of strategic alternatives, based upon, among other things, the fact that Moelis is an internationally recognized investment banking firm that has substantial experience in merger and acquisition transactions. In October 2010, the Transatlantic board of directors disbanded the Special Committee (since AIG was no longer a significant stockholder of Transatlantic) and established a new strategy committee of the board of directors (the “Strategy Committee”), comprised of Messrs. Press, Chippendale, Foos and Stephen P. Bradley, each of whom are independent, to oversee Transatlantic’s review of strategic alternatives. From time to time since AIG’s June 2009 offering, at the direction of the board of directors of Transatlantic and the Strategy Committee, Transatlantic’s senior management engaged in preliminary discussions regarding possible business combination transactions with a number of insurance and reinsurance companies. Until the negotiations described below, these discussions did not proceed past preliminary proposals, execution of confidentiality and standstill agreements and limited exchanges of non-public information.
 
During 2010, Allied World engaged in strategic discussions with certain insurance and reinsurance companies, including a potential business combination and two strategic acquisitions in Canada and Europe. In each case, Allied World determined that the transaction valuations sought did not provide adequate value to Allied World and its shareholders.
 
During the period from February 11, 2011 to March 11, 2011, Robert F. Orlich, the Chief Executive Officer of Transatlantic, and/or Michael C. Sapnar, the current Chief Operating Officer of Transatlantic, engaged in very preliminary discussions with Scott A. Carmilani, the Chairman and Chief Executive Officer of Allied World, concerning the possibility of a strategic business combination transaction involving the two companies. On March 11, 2011, Mr. Carmilani met with Messrs. Orlich and Sapnar to discuss the possibility of the companies entering into a mutual confidentiality agreement, as well as the engagement of financial advisors by both companies, in connection with a potential transaction. The individuals also had very preliminary discussions regarding governance matters in connection with a possible transaction.
 
On March 13, 2011, the Allied World board of directors met by teleconference with members of Allied World’s senior management in attendance, during which Mr. Carmilani reported on his initial conversations with Messrs. Orlich and Sapnar. At the meeting, the Allied World board of directors requested Allied World’s senior management team to engage in further discussions with Transatlantic regarding the possibility of a strategic business combination involving the two companies and to report back to the board following such discussions. The Allied World board of directors also requested the retention of Deutsche Bank as Allied World’s financial advisor in connection with the review of the possible transaction, based upon, among other things, the fact that Deutsche Bank is an internationally recognized investment banking firm that has substantial experience in merger and acquisition transactions and the high-quality service that Deutsche Bank provides. Shortly thereafter, representatives of Allied World’s senior management approached representatives of Deutsche Bank to discuss whether Deutsche Bank would be available to assist Allied World in connection with evaluating the proposed transaction, and Deutsche Bank was then selected to serve as the company’s financial advisor.
 
On March 16, 2011, in connection with the regularly scheduled March 17, 2011 Transatlantic board of directors meeting, the Strategy Committee held a meeting (at which all of Transatlantic’s directors were in attendance) to discuss Messrs. Orlich and Sapnar’s conversations with Mr. Carmilani and the benefits of a potential strategic combination transaction between the companies. Members of Transatlantic’s senior management and representatives from Gibson, Dunn & Crutcher LLP, Transatlantic’s outside legal counsel (“Gibson Dunn”), and Moelis participated in this meeting. Representatives of Moelis reviewed with the directors recent M&A activity in the property and casualty insurance and reinsurance industry and provided an overview of potential business combination partners, including Allied World. Mr. Orlich described management’s views as to the business and strategic benefits of a potential strategic combination transaction with Allied World, including the increased size and capital position of the combined companies, the combination of strong primary insurance and reinsurance businesses, and certain expected synergies. Mr. Orlich also noted that

Transatlantic and Allied World each had strong and complementary underwriting and risk management cultures and that Transatlantic has been conducting insurance and reinsurance business with Allied World for many years and has had very positive experiences with Allied World.

Starting on March 27, 2011 and continuing until the execution of the merger agreement on June 12, 2011, the management teams of Transatlantic and Allied World, together with their respective financial, actuarial, tax and legal advisors, performed extensive due diligence on each other through a series of meetings, telephonic discussions and a review of both public and non-public information.
 
Beginning in late March 2011, members of Allied World’s senior management team, together with Allied World’s financial and legal advisors, discussed with members of Allied World’s board of directors at varying times the status of ongoing due diligence and discussions with Transatlantic. In particular, Mr. Carmilani provided continuous updates to Allied World’s lead independent director regarding various issues relating to the transaction, which were in turn reported to other members of the board; met in person with the co-chairs of the Allied World audit committee to discuss items related to financial statements, independent auditors and the internal audit function in connection with a possible transaction; discussed compensation matters with the chairman of Allied World’s compensation committee; analyzed issues relating to the potential combined company’s investment portfolio with the chairman of Allied World’s investment committee; and engaged in individual discussions with directors from time to time regarding structuring, governance, valuation and other issues related to the potential transaction.
 
On April 4, 2011, Transatlantic and Allied World, together with their financial and legal advisors, had a telephonic organizational meeting to discuss the process and timeline for a proposed transaction, including, among other things, due diligence matters, tax issues, regulatory issues, rating agencies, antitrust issues and capital management.
 
On April 6, 2011, members of Transatlantic’s senior management met with members of Allied World’s senior management and discussed a potential strategic combination transaction and various issues related thereto, including, among other things, the potential business and strategic benefits of a combination, a potential deal structure, due diligence matters, proposed timeline and cultural issues.

Following the meeting on April 6, 2011, the Strategy Committee held a telephonic meeting (at which additional Transatlantic directors were in attendance), attended by members of Transatlantic’s senior management and representatives of Gibson Dunn. At this meeting, members of management updated the Strategy Committee regarding additional discussions that had occurred with Allied World, including with respect to due diligence matters.

Messrs. Foos, Press and John. L. McCarthy, constituting all the members of Transatlantic’s audit committee, authorized management to engage PWC as Transatlantic’s tax advisor in connection with a possible transaction with Allied World. Transatlantic’s senior management also informed the Strategy Committee that Transatlantic had

retained an internationally-recognized consulting firm to perform an independent review of Allied World’s loss reserves in addition to the due diligence review being performed by Transatlantic’s actuaries. Members of management and representatives of Gibson Dunn reviewed with the Strategy Committee the rationale for entering into, and the proposed terms of, an exclusivity agreement with Allied World. Representatives of Gibson Dunn discussed with the directors the applicable legal standards in the context of considering a strategic combination transaction of the type being proposed. Following a discussion, the Strategy Committee authorized Transatlantic’s management to enter into a 30-day exclusivity agreement with Allied World. In addition, Transatlantic’s board of directors had requested that representatives of Goldman Sachs and Moelis describe any recent prior relationships between their respective firms and Allied World. After consideration and discussion, Transatlantic’s board of directors then selected Goldman Sachs and Moelis to act as Transatlantic’s independent financial advisors in connection with the proposed strategic combination transaction based upon, among other things, the fact that they are internationally recognized investment banking firms that have substantial experience in transactions similar to the proposed strategic combination transaction and the high quality of service that both firms had provided to Transatlantic in the past. The Transatlantic board of directors also determined to seek a fairness opinion from Moelis in connection with the potential transaction with Allied World because, among other things, Moelis had no prior relationships with Allied World.
 
On April 8, 2011, the Allied World board of directors met by teleconference with members of Allied World’s senior management in attendance, during which management reviewed certain aspects of the possible transaction with Transatlantic, including governance matters, loss reserves and deal structures.

Starting in mid-April through late May, Transatlantic and Allied World, together with their respective advisors, evaluated a variety of possible transaction structures for a merger of equals transaction and jointly determined that merging Transatlantic into a subsidiary of Allied World, with Allied World surviving as the publicly-traded parent company, represented the most desirable structure for the potential transaction.
 
During April 2011 and through the execution of the merger agreement on June 12, 2011, members of Allied World’s senior management team, together with Allied World’s financial and legal advisors, continued to provide updates to members of Allied World’s board of directors regarding the ongoing discussions with Transatlantic.

On April 25, 2011, representatives of Goldman Sachs and Moelis contacted representatives of Deutsche Bank to discuss certain valuation issues and informed them that Transatlantic would not be willing to enter into a transaction based on a market-to-market valuation of the two companies and would expect the transaction to be based on book-to-book valuation, with appropriate adjustments for reserves, goodwill and litigation matters. Allied World’s financial advisors indicated that Allied World was not contemplating a transaction based on a market-to-market valuation but that it would not be willing to enter into a transaction based on a tangible book-to-tangible book valuation of the two companies.

Representatives of Moelis then presented to the board various financial analyses of the proposed merger as further described below under “— Opinion of Transatlantic’s Financial Advisor.” In connection with the deliberation by the Transatlantic board, Moelis delivered to the Transatlantic board its oral opinion, which was subsequently confirmed by delivery of a written opinion dated June 12, 2011, to the effect that, as of such date and based upon and subject to the assumptions, procedures, factors, qualifications and limitations set forth in such written opinion, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to the holders of shares of Transatlantic’s common stock, as more fully described below under “— Opinion of Transatlantic’s Financial Advisor.” Following these discussions, the Transatlantic board unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, were advisable and in the best interests of Transatlantic and its stockholders and voted unanimously to approve the merger agreement.
 
Following the respective board meetings of Allied World and Transatlantic, all agreements were finalized and the merger agreement was then executed by Transatlantic, Allied World and Merger Sub. Later that day, Transatlantic and Allied World issued a joint press release announcing the proposed transaction.
 
Allied World’s Reasons for the Merger; Recommendations of the Allied World Board of Directors
 
In reaching its decision to approve the merger agreement and recommend approval of both the issuance of Allied World shares to Transatlantic stockholders pursuant to the merger and the adoption of Allied World’s amended Articles of Association, the Allied World board of directors consulted with Allied World’s management, as well as with Allied World’s legal and financial advisors, and also considered a number of factors that the Allied World board of directors viewed as supporting its decisions, including, but not limited to, the following:
 
  •  the potential to create a leading specialty focused insurance and reinsurance company with a global reach;
 
  •  the potential for revenue growth and synergies to generate additional free cash flow available for investment and expansion opportunities;
 
  •  that although no assurance can be given that any level of operating and structural synergies would be achieved following the completion of the merger, management estimated significant synergies in the principal areas of reduced public company costs, consolidated corporate governance, reduced labor, shared platform costs and structural flexibility in allocation of capital;
 
  •  that the greater scale, scope and reach of the combined company, including its enhanced business mix diversity and expanded European and Asian presence, should make it a more attractive partner for potential customers with both national and international businesses and help to enhance brand recognition;
 
  •  the fact that the merger will create a company with a greater size and economies of scale, enabling it to have incremental excess capital, greater capital flexibility, ability to respond to competitive pressures, greater diversification opportunities and an increased opportunity to compete profitably;
 
  •  that although no assurance can be given on any level of reaction by any independent rating agency, the pro forma independent rating agency capital adequacy models of the combined company, generate increased quantitative capital adequacy scores and, potentially improved debt and financial strength ratings for the combined company;

Table of Contents

 
  •  the combination of the businesses through the merger will result in greater product offerings and improved market positions;
 
  •  the combination of the strong and experienced management teams from Allied World and Transatlantic will add significant value to the combined company;
 
  •  the addition of a global reinsurance platform will provide Allied World with access to a profitable business segment that will allow Allied World to better serve its customers;
 
  •  the significant role in the combined company to be played by members of management and the current board of directors of Allied World, including Scott A. Carmilani, Allied World’s current Chairman, President and Chief Executive Officer (who will continue as the combined company’s President and Chief Executive Officer), and other Allied World employees, which the Allied World board of directors believed would enhance the prospects of the combined company after completion of the merger for the benefit of Allied World shareholders; and
 
  •  the financial analyses presented by Deutsche Bank to the Allied World board of directors described below under “— Opinion of Allied World’s Financial Advisor,” and the opinion of Deutsche Bank rendered to the Allied World board of directors that, as of the date such merger agreement was signed, based upon and subject to the factors and assumptions set forth in its written opinion. See “— Opinion of Allied World’s Financial Advisor.”
 
In addition to considering the factors described above, the Allied World board of directors also considered the following factors:
 
  •  its knowledge of Allied World’s business, operations, financial condition, earnings and prospects and of Transatlantic’s business, operations, financial condition, earnings and prospects, taking into account the results of Allied World’s due diligence review of Transatlantic;
 
  •  the integration risks, resulting from similar cultures focused on underwriting discipline and risk management, the overlap in use of information systems, limited business overlap and the proven integration track record of Allied World;
 
  •  the anticipated market capitalization, liquidity and capital structure of the combined company;
 
  •  the projected financial results of Allied World as a standalone company and the ability of Allied World to achieve strategic goals previously established by the Allied World board of directors;
 
  •  the fact that the exchange ratio of 0.88 Allied World shares for each share of Transatlantic common stock is fixed, which the Allied World board of directors believed was consistent with market practice for mergers of this type and with the strategic purpose of the merger; and
 
  •  the terms and conditions of the merger agreement and the likelihood of completing the merger on the anticipated schedule.
 
The Allied World board of directors weighed the foregoing against a number of potentially negative factors, including:
 
  •  the restrictions on the conduct of Allied World’s business during the period between execution of the merger agreement and the consummation of the merger, including the inability to repurchase shares;
 
  •  the potential effect of the merger on Allied World’s overall business, including its relationships with customers, employees, suppliers and regulators;
 
  •  the challenges inherent in combining the businesses, operations and workforces of two companies, including the potential for (i) unforeseen difficulties in integrating operations and systems, (ii) the possible distraction of management attention for an extended period of time and (iii) difficulties in assimilating employees;
 
  •  the substantial costs to be incurred in connection with the merger, including the costs of integrating the businesses of Allied World and Transatlantic and the transaction expenses arising from the merger;


52


Table of Contents

 
  •  the risk that governmental entities may oppose or refuse to approve the merger or impose conditions on Allied World and/or Transatlantic prior to approving the merger that may adversely impact the ability of the combined company to realize synergies that are projected to occur in connection with the merger;
 
  •  the risk that, despite the combined efforts of Allied World and Transatlantic prior to the consummation of the merger, the combined company may lose key personnel;
 
  •  the possibility of merger arbitrage activity as a result of the stock price premium being paid;
 
  •  the risk that Transatlantic’s loss reserves may prove to be inadequate;
 
  •  the risk that the combined company, with increased policies and geographic coverage, will have a level of volatility higher than Allied World’s after the merger as a result of additional catastrophe risk exposure;
 
  •  the risk of not capturing all of the anticipated operational and structural synergies between Allied World and Transatlantic and the risk that other anticipated benefits may not be realized; and
 
  •  the risks of the type and nature described under the heading “Risk Factors,” and the matters described under the heading “Special Note Regarding Forward-Looking Statements.”
 
This discussion of the information and factors considered by the Allied World board of directors in reaching its conclusions and recommendation includes the material factors considered by the board, but is not intended to be exhaustive. In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the Allied World board of directors did not find it practicable, and did not attempt, to quantify, rank or assign any relative or specific weights to the various factors that it considered in reaching its determination to approve the merger agreement and to recommend that Allied World shareholders vote in favor of the share capital increase proposals, the NYSE share issuance proposal, the name change proposal, the election of directors proposal, the capital reduction proposal and the Stock Incentive Plan proposal. The Allied World board of directors conducted an overall analysis of the factors described above, including through discussions with, and questioning of, Allied World’s management and outside legal and financial advisors regarding certain of the matters described above. In considering the factors described above, individual members of the Allied World board of directors may have given differing weights to different factors.
 
The Allied World board of directors unanimously approved the merger agreement and determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and in the best interests of Allied World. The Allied World board of directors unanimously recommends that Allied World shareholders vote “FOR” the proposals set forth herein.
 
Opinion of Allied World’s Financial Advisor
 
Opinion of Deutsche Bank Securities Inc.
 
Allied World engaged Deutsche Bank pursuant to a letter agreement dated June 2, 2011, to act as its financial advisor in connection with the merger. At the meeting of the Allied World board of directors on June 12, 2011, Deutsche Bank rendered an oral and written opinion, to the Allied World board of directors to the effect that, based upon and subject to the assumptions, limitations, qualifications and conditions set forth in the opinion, as of the date of such opinion, the exchange ratio was fair, from a financial point of view, to Allied World.
 
The full text of the written opinion of Deutsche Bank, dated June 12, 2011, which sets forth, among other things, the assumptions made, matters considered, and limitations, qualifications and conditions of the review undertaken by Deutsche Bank in connection with the opinion, is attached as Annex B to this joint proxy statement/prospectus and is incorporated herein by reference. Allied World shareholders are urged to read Deutsche Bank’s opinion carefully and in its entirety. Deutsche Bank expressed no opinion as to the merits of the underlying decision by Allied World to engage in the merger or the relative

Table of Contents

merits of the merger as compared to any alternative transactions or business strategies, nor did Deutsche Bank express an opinion as to how any holder of Allied World shares should vote with respect to the merger.
 
In connection with Deutsche Bank’s role as financial advisor to Allied World, and in arriving at its opinion, Deutsche Bank reviewed certain publicly available financial and other information concerning Allied World and Transatlantic, including certain statutory statements filed by the insurance subsidiaries of both Allied World and Transatlantic. Deutsche Bank also reviewed certain internal analyses, financial forecasts and other information relating to Allied World and Transatlantic prepared by management of Allied World and Transatlantic, respectively, and certain analyses and financial forecasts relating to Transatlantic prepared by management of Allied World. Deutsche Bank also reviewed certain reports regarding Transatlantic’s reserves for losses and loss adjustment expenses prepared for Allied World by third party actuaries. Deutsche Bank also held discussions with certain senior officers and other representatives and advisors of Allied World and Transatlantic regarding the businesses and prospects of Allied World, Transatlantic and the combined company, including certain cost savings and operating synergies jointly projected by the managements of Allied World and Transatlantic to result from the merger. In addition, Deutsche Bank:
 
  •  reviewed the reported prices and trading activity for both the Allied World shares and the Transatlantic common stock;
 
  •  to the extent publicly available, compared certain financial and stock market information for Allied World and Transatlantic with similar information for certain other companies it considered relevant whose securities are publicly traded;
 
  •  to the extent publicly available, reviewed the financial terms of certain recent business combinations which it deemed relevant;
 
  •  reviewed a draft of the merger agreement, dated June 10, 2011; and
 
  •  performed such other studies and analyses and considered such other factors as it deemed appropriate.
 
Deutsche Bank did not assume responsibility for independent verification of, and did not independently verify, any information, whether publicly available or furnished to it, concerning Allied World or Transatlantic, including, without limitation, any financial information considered in connection with the rendering of its opinion. Accordingly, for purposes of its opinion, Deutsche Bank, with the permission of the Allied World board of directors, assumed and relied upon the accuracy and completeness of all such information. Deutsche Bank did not conduct a physical inspection of any of the properties or assets, and did not prepare or obtain any independent evaluation or appraisal of any of the assets or liabilities (including, without limitation, any contingent, derivative or off-balance-sheet assets and liabilities), of Allied World or Transatlantic or any of their respective subsidiaries, nor did Deutsche Bank evaluate the solvency or fair value of Allied World or Transatlantic under any state or federal law relating to bankruptcy, insolvency or similar matters. With respect to the financial forecasts, including, without limitation, the analyses and forecasts of the amount and timing of certain cost savings, operating efficiencies, revenue effects, financial synergies and other strategic benefits projected by Allied World to be achieved as a result of the merger (collectively, the “Synergies”), made available to Deutsche Bank and used in its analyses, Deutsche Bank assumed, with the permission of the Allied World board of directors, that they had been reasonably prepared on bases reflecting the best currently available estimates and judgments of the managements of Allied World and Transatlantic, as applicable, as to the matters covered thereby. In rendering its opinion, Deutsche Bank expressed no view as to the reasonableness of such forecasts and projections, including, without limitation, the Synergies, or the assumptions on which they were based. Deutsche Bank’s opinion was necessarily based upon economic, market and other conditions as in effect on, and the information made available to it as of, the date of the opinion. Deutsche Bank expressly disclaimed any undertaking or obligation to advise any person of any change in any fact or matter affecting its opinion of which it becomes aware after the date of its opinion.
 
For purposes of rendering its opinion, Deutsche Bank assumed, with the permission of the Allied World board of directors, that, in all respects material to its analysis, the merger would be consummated in accordance with its terms, without any material waiver, modification or amendment of any term, condition or


54


Table of Contents

agreement. Deutsche Bank also assumed that all material governmental, regulatory, contractual or other approvals and consents required in connection with the consummation of the merger would be obtained and that in connection with obtaining any necessary governmental, regulatory, contractual or other approvals and consents, no material restrictions, terms or conditions would be imposed. Deutsche Bank is not a legal, regulatory, tax or accounting expert and Deutsche Bank relied on the assessments made by Allied World and its advisors with respect to such issues. In particular, Deutsche Bank assumed, with the permission of the Allied World board of directors, that Transatlantic will be the accounting acquirer in the merger. Deutsche Bank is also not an expert in the evaluation of reserves for losses and loss adjustment expenses and was not requested to, and did not, make any actuarial determinations or evaluations or attempt to evaluate actuarial assumptions. Deutsche Bank made no analysis of, and did not express any view with respect to, the adequacy of Allied World’s or Transatlantic’s loss and loss adjustment expense reserves. Representatives of Allied World informed Deutsche Bank, and Deutsche Bank has further assumed, that the final terms of the merger agreement would not differ materially from the terms set forth in the drafts it reviewed.
 
The Deutsche Bank opinion was approved and authorized for issuance by a fairness opinion review committee and was addressed to, and for the use and benefit of, the Allied World board of directors in connection with and for the purposes of its evaluation of the merger and is not a recommendation to the shareholders of Allied World as to how they should vote with respect to the merger, the amendment of Allied World’s Articles or the issuance of Allied World shares in the merger, in each case as contemplated by the merger agreement. The Deutsche Bank opinion was limited to the fairness, from a financial point of view, of the exchange ratio to Allied World and did not address any other terms of the merger or the merger agreement, is subject to the assumptions, limitations, qualifications and other conditions contained therein and is necessarily based on the economic, market and other conditions, and information made available to Deutsche Bank, as of the date of the opinion. Deutsche Bank was not asked to, and its opinion did not, address the fairness of the merger, or any consideration received in connection therewith, to the holders of any other class of securities, creditors or other constituencies of Allied World, nor did it address the fairness of the contemplated benefits of the merger. Deutsche Bank did not express any view or opinion as to the underlying decision by Allied World to engage in the merger or the relative merits of the merger as compared to any alternative transactions or business strategies. In addition, Deutsche Bank did not express any view or opinion as to the fairness, financial or otherwise, of the amount or nature of any compensation payable to or to be received by any of the officers, directors, or employees of any parties to the merger, or any class of such persons, relative to the exchange ratio. The Deutsche Bank opinion did not in any manner address the prices at which the Allied World shares or any other securities would trade following the announcement or consummation of the merger.
 
The following is a summary of the material financial analyses contained in the presentation that was made by Deutsche Bank to the Allied World board of directors on June 12, 2011 and that were used by Deutsche Bank in connection with rendering its opinion described above. The following summary, however, does not purport to be a complete description of the financial analyses performed by Deutsche Bank, nor does the order in which the analyses are described represent the relative importance or weight given to the analyses by Deutsche Bank. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are alone not a complete description of Deutsche Bank’s financial analyses. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before June 10, 2011, and is not necessarily indicative of current market conditions.

Historical Exchange Ratio Analysis
 
Deutsche Bank calculated, reviewed and analyzed the average historical exchange ratios implied by dividing the daily closing prices of Transatlantic’s common stock over Allied World’s shares, over historical periods prior to June 10, 2011. The results of this analysis are as follows:
 
         
    Average Exchange Ratios
 
Current (as of June 10, 2011)
    0.76 x

    0.87  
2-year
    0.99  
 
In addition, Deutsche Bank reviewed the range of exchange ratios over the 52-week period prior to June 10, 2011. Deutsche Bank found that the exchange ratio ranged from 0.74x to 1.07x over that period. Deutsche Bank noted that the exchange ratio of 0.88x fell within that range.
 
Trading Range Analysis
 
Deutsche Bank reviewed the 52-week trading range of Allied World shares and Transatlantic’s common stock measured as of June 10, 2011. Deutsche Bank found that the price per share of Allied World’s shares over that period ranged from $45 to $65 and that Transatlantic’s common stock over that period ranged from $44 to $54. Based on the foregoing, Deutsche Bank calculated an implied exchange ratio range of 0.68 to 1.21x shares of Allied World to be issued in exchange for one share of Transatlantic common stock. The low exchange ratio represents the ratio of the lowest Transatlantic value per share and the highest Allied World value per share over the 52-week period considered. The high exchange ratio represents the ratio of the highest Transatlantic value per share and the lowest Allied World value per share over the 52-week period considered. Deutsche Bank noted that the exchange ratio of 0.88x fell within that range.
 
Contribution Analysis
 
Based upon the exchange ratio of 0.88 Allied World shares per share of Transatlantic common stock to be effected in the merger and the closing price of $58.07 per Allied World share on June 10, 2011, Deutsche Bank calculated that the pro forma fully diluted ownership of Allied World and Transatlantic shareholders in the combined company was approximately 42% and 58%, respectively. Deutsche Bank then

Table of Contents

compared such pro forma fully diluted ownership percentages of Allied World and Transatlantic shareholders to Allied World’s and Transatlantic’s respective relative contributions to the combined company based upon current fully diluted market capitalization for each company on a stand-alone basis as of June 10, 2011, total assets, shareholders’ equity and shareholders’ tangible equity for each company on a stand-alone basis as of March 31, 2011, as well as each company’s relative contribution to actual after-tax operating income for 2010 and estimated after-tax operating income for 2011, 2011 (normalized for a catastrophe loss ratio of 5%), 2012 and 2013 based upon estimates prepared by the management of Allied World and Transatlantic for their respective companies. The results of these calculations are summarized as follows:
 
                 
    Relative Contribution
    Allied World   Transatlantic
 
Financial metrics
               
Current fully diluted market capitalization (as of 6/10/11)

2013 Estimated after-tax operating income
    41       59  
 
In addition to noting the relative pro forma ownership percentages for holders of Allied World shares and Transatlantic common stock described above, Deutsche Bank noted that the board of directors of the combined company would consist of 11 directors, five appointed by Allied World and six appointed by Transatlantic and that such relative ownership amounts and board composition are consistent with precedent mergers of equals.
 
Implied Exchange Ratio Analysis
 
Deutsche Bank assessed the fairness of the exchange ratio by deriving values for each of Allied World and Transatlantic using several valuation methodologies, including an analysis of comparable companies using valuation multiples from selected publicly-traded companies, and dividend discount analysis, each of which is described in more detail in the summaries set forth below. Each of these methodologies was used to generate implied per share valuation ranges on a fully-diluted common share basis. The implied per share valuation ranges were used to assess the exchange ratio implied by each methodology.
 
The following table outlines the ranges of approximate implied values per Allied World share and shares of Transatlantic common stock and the implied exchange ratios derived using each of these methodologies. With respect to any given range of exchange ratios, the low exchange ratio represents the ratio of the lowest Transatlantic value per share and the highest Allied World value per share, and the high exchange ratio represents the ratio of the highest Transatlantic value per share and the lowest Allied World value per share.

Comparable Companies Analysis — Allied World
 
Deutsche Bank reviewed and compared certain financial information and commonly used valuation measurements for Allied World to corresponding financial information and measurements for the following selected companies.
 
  •  Arch Capital Group Ltd.
 
  •  Argo Group International Holdings, Ltd.
 
  •  Aspen Insurance Holdings Limited
 
  •  Axis Capital Holdings Limited
 
  •  Endurance Specialty Holdings Ltd.
 
  •  HCC Insurance Holdings, Inc.
 
  •  Markel Corporation
 
  •  The Navigators Group, Inc.
 
  •  RLI Corp.
 
  •  W.R. Berkley Corporation
 
Although none of the selected companies is either identical or directly comparable to Allied World, the companies included were chosen because they are publicly traded companies with operations that, for purposes of analysis, may be considered similar to certain operations of Allied World. Accordingly, the analysis of publicly traded comparable companies was not simply mathematical. Rather, it involved complex considerations and qualitative judgments, reflected in Deutsche Bank’s opinion, concerning differences in financial and operating characteristics of the selected companies and other factors that could affect the public trading value of such companies.
 
With respect to each of the selected companies and Allied World, Deutsche Bank calculated the following trading multiples:
 
  •  the multiple of price to book value per share, which we refer to as “P/B”;
 
  •  the multiple of price to tangible book value per share, which we refer to as “P/B Tangible”; and
 
  •  the multiple of price to estimated operating earnings per share, which we refer to as “P/E,” for 2012.
 
Deutsche Bank did not use the multiple of price to estimated operating earnings per share for 2011 because it believed extraordinary catastrophe losses in the first quarter of 2011 (including Japan, New Zealand


58


Table of Contents

and Australia losses) resulted in estimated operating earnings for 2011 being non-representative of potential future financial performance with disproportionate impact on each comparable company.
 
The trading multiples of Allied World and the selected companies were calculated using the closing prices of the Allied World shares and the common stock of the selected companies on June 10, 2011 and were based upon the most recent publicly available information, Allied World’s management’s estimates and analysts’ consensus earnings estimates for 2012 provided by CapitalIQ. The results of these analyses are summarized as follows:

Based in part on the trading multiples described above, Deutsche Bank selected certain reference ranges of multiples and calculated corresponding ranges of implied equity values per Allied World share as follows:
 
  •  Deutsche Bank applied multiples of price to book value per share ranging from 0.75x to 0.95x to the book value per Allied World share as of March 31, 2011;
 
  •  Deutsche Bank applied multiples of price to tangible book value per share ranging from 0.80x to 1.00x to the tangible book value per Allied World share as of March 31, 2011; and
 
  •  Deutsche Bank applied multiples of price to estimated after-tax operating earnings ranging from 8.0x to 10.0x to the estimated after-tax operating earnings of Allied World for 2012 based on the Allied World estimates.
 
The ranges of approximate implied equity values per Allied World share resulting from the foregoing calculations, which are the same as the ranges of implied equity values per share used in the Implied Exchange Ratio Analysis discussed above, are presented in the following table:

Deutsche Bank did not use the multiple of price to estimated operating earnings per share for 2011 because it believed extraordinary catastrophe losses in the first quarter of 2011 (including Japan, New Zealand and Australia losses) resulted in estimated operating earnings for 2011 being non-representative of potential future financial performance with disproportionate impact on each comparable company.
 
The trading multiples of Transatlantic and the selected companies were calculated using the closing prices of the Transatlantic common stock and the common stock of the selected companies on June 10, 2011 and were based upon the most recent publicly available information, Transatlantic’s management estimates and analysts’ consensus earnings estimates for 2012 provided by CapitalIQ. The results of these analyses are summarized as follows:

Based in part on the trading multiples described above, Deutsche Bank selected certain reference ranges of multiples and calculated corresponding ranges of implied equity values per share of Transatlantic common stock as follows:
 
  •  Deutsche Bank applied multiples of price to book value per share ranging from 0.70x to 1.00x to the book value per share of Transatlantic common stock as of March 31, 2011;
 
  •  Deutsche Bank applied multiples of price to tangible book value per share ranging from 0.70x to 1.05x to the tangible book value per share of Transatlantic common stock as of March 31, 2011; and
 
  •  Deutsche Bank applied multiples of price to estimated after-tax operating earnings ranging from 6.0x to 10.0x to the estimated after-tax operating earnings of Transatlantic for 2012 based on the Transatlantic estimates.
 
The ranges of approximate implied equity values per share of Transatlantic common stock resulting from the foregoing calculations, which are the same as the ranges of implied equity values per share used in the Implied Exchange Ratio Analysis discussed above, are presented in the following table:

Dividend Discount Analysis — Allied World
 
Based on the Allied World estimates, Deutsche Bank performed a dividend discount analysis to determine a range of implied present values per Allied World share, assuming Allied World continued to operate as a standalone company. The values were determined by adding the present value of the estimated free cash flow per share for the nine months ended December 31, 2011 and for the years 2012 through 2015 and the present value of the estimated terminal value per Allied World share as of the end of 2015. Deutsche Bank calculated a range of present equity values for Allied World as the sum of (1) the present value of the estimated cash flow per share for the nine months ended December 31, 2011 and for the years 2012 through 2015 using discount rates ranging from 8.5% to 10.5%, which were chosen by Deutsche Bank based upon an analysis of the cost of equity of Allied World, and (2) the present value of illustrative terminal value per share derived by applying a range of price to book value multiples and price to earnings multiples to Allied World’s estimated shareholders’ equity and net income and applying discount rates ranging from 8.5% to 10.5% to such terminal values. For the terminal value based on price to book value multiples, Deutsche Bank applied multiples ranging from 0.90x to 1.10x to Allied World’s estimated shareholders’ equity for 2015. Based on the above analysis, Deutsche Bank determined a range of present values per Allied World share of approximately $70 to $86. For the terminal value based on price to earnings multiples, Deutsche Bank applied multiples ranging from 8.0x to 10.0x to Allied World’s estimated net income for 2015. Based on the above analysis, Deutsche Bank determined a range of present values per Allied World share of approximately $68 to $85. Deutsche Bank selected the terminal value multiples used in this analysis based upon the current and historical trading values and multiples of Allied World and the selected companies discussed in the Comparable Companies Analysis above.
 
Dividend Discount Analysis — Transatlantic
 
Based on the Transatlantic estimates, Deutsche Bank performed a dividend discount analysis to determine a range of implied present values per share of Transatlantic common stock, assuming Transatlantic continued to operate as a standalone company. The values were determined by adding the present value of the estimated free cash flow per share for the nine months ended December 31, 2011 and for the years 2012 through 2015 and the present value of the estimated terminal value per share of Transatlantic common stock as of the end of 2015. Deutsche Bank calculated a range of present equity values for Transatlantic as the sum of (1) the present

value of the estimated cash flow per share for the nine months ended December 31, 2011 and for the years 2012 through 2015 using discount rates ranging from 9% to 11%, which were chosen by Deutsche Bank based upon an analysis of the cost of equity of Transatlantic, and (2) the present value of illustrative terminal value per share derived by applying a range of price to book value multiples and price to earnings multiples to Transatlantic’s estimated shareholders’ equity and net income and applying discount rates ranging from 9% to 11% to such terminal values. For the terminal value based on price to book value multiples, Deutsche Bank applied multiples ranging from 0.85x to 1.15x to Transatlantic’s estimated shareholders’ equity for 2015. Based on the above analysis, Deutsche Bank determined a range of present values per share of Transatlantic common stock of approximately $57 to $76. For the terminal value based on price to earnings multiples, Deutsche Bank applied multiples ranging from 8.0x to 10.0x to Transatlantic’s estimated net income for 2015. Based on the above analysis, Deutsche Bank determined a range of present values per share of Transatlantic common stock of approximately $56 to $70. Deutsche Bank selected the terminal value multiples used in this analysis based upon the current and historical trading values and multiples of the selected companies discussed in the Comparable Companies Analysis above.
 
The preparation of a fairness opinion is a complex process involving the application of subjective business judgment in determining the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, is not readily susceptible to summary description. Deutsche Bank believes that its analyses must be considered as a whole and that considering any portion of such analyses and of the factors considered without considering all analyses and factors could create a misleading view of the process underlying the opinion. In arriving at its fairness determination, Deutsche Bank did not assign specific weights to any particular analyses.
 
In conducting its analyses and arriving at its opinion, Deutsche Bank utilized a variety of generally accepted valuation methods. The analyses were prepared solely for the purpose of enabling Deutsche Bank to provide its opinion to the Allied World board of directors as to the fairness, from a financial point of view, to Allied World of the exchange ratio described above as of the date of its opinion and do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold, which are inherently subject to uncertainty. In connection with its analyses, Deutsche Bank made, and was provided by the management of Allied World with, numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Deutsche Bank, Transatlantic or Allied World. Analyses based on estimates or forecasts of future results are not necessarily indicative of actual past or future values or results, which may be significantly more or less favorable than suggested by such analyses. Because such analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of Transatlantic, Allied World or their respective advisors, none of Transatlantic, Allied World, Deutsche Bank nor any other person assumes responsibility if future results or actual values are materially different from these forecasts or assumptions.
 
The terms of the merger, including the exchange ratio, were determined through arm’s-length negotiations between Allied World and Transatlantic and were approved by the Allied World board of directors. Representatives of Deutsche Bank provided advice to Allied World during these negotiations. Deutsche Bank, however, did not recommend any specific exchange ratio to Allied World or its board of directors or that any specific exchange ratio constituted the only appropriate exchange ratio for the merger. The decision to enter into the merger was solely that of the Allied World board of directors. As described above, the opinion and presentation of Deutsche Bank to the Allied World board of directors were only one of a number of factors taken into consideration by the Allied World board of directors in making its determination to approve the merger agreement and the transactions contemplated by it, including the merger.
 
Allied World selected Deutsche Bank as its financial advisors in connection with the merger based on Deutsche Bank’s qualifications, expertise, reputation and experience in mergers and acquisitions. Pursuant to the engagement letter dated June 2, 2011 between Allied World and Deutsche Bank, Allied World agreed to pay Deutsche Bank (i) a fee (an “Opinion Fee”) equal to $2.5 million payable upon the delivery of its opinion (or upon Deutsche Bank advising Allied World that it was unable to render an opinion) and (ii) in the event the merger is consummated, a fee equal to $14.5 million payable at the time of closing less the amount of any Opinion Fee previously paid. If the merger is not completed and Allied World receives a break-up fee, lock-up

option, topping fee or other termination fee or other similar payment, Deutsche Bank is entitled to receive a fee equal to $5 million. Allied World has also agreed to reimburse Deutsche Bank for reasonable fees and disbursements of Deutsche Bank’s counsel and Deutsche Bank’s reasonable travel and other out-of-pocket expenses incurred in connection with the merger or otherwise arising out of the retention of Deutsche Bank under the engagement letter. Allied World has also agreed to indemnify Deutsche Bank and certain related persons to the full extent lawful against certain liabilities, including certain liabilities under the U.S. federal securities laws arising out of its engagement or the merger.
 
Deutsche Bank is an internationally recognized investment banking firm experienced in providing advice in connection with mergers and acquisitions and related transactions. Deutsche Bank is an affiliate of Deutsche Bank AG, which, together with its affiliates, we refer to as the “Deutsche Bank Group.” One or more members of the Deutsche Bank Group have, from time to time, provided investment banking, commercial banking (including extension of credit) and other financial services to Allied World, Transatlantic or their respective affiliates for which it has received compensation, including having acted as a book-running manager in a public offering of senior notes by Allied World in November 2010, acting as a lender of Allied World’s senior credit facility and acting as an asset manager for certain investment portfolios of Transatlantic. The Deutsche Bank Group may also provide investment and commercial banking services to Allied World, Transatlantic or their respective affiliates in the future, for which the Deutsche Bank Group would expect to receive compensation. In the ordinary course of business, members of the Deutsche Bank Group may actively trade in the securities and other instruments and obligations of Allied World and Transatlantic (or their respective affiliates) for their own accounts and for the accounts of their customers. Accordingly, the Deutsche Bank Group may at any time hold a long or short position in such securities, instruments and obligations. In addition, as of June 12, 2011, Deutsche Bank and affiliates owned approximately 250,000 shares of Transatlantic common stock.
 
Certain Allied World Prospective Financial Information
 
Allied World does not as a matter of course make public long-term forecasts as to future performance or other prospective financial information beyond the current fiscal year, and Allied World is especially wary of making forecasts or projections for extended periods due to the unpredictability of the underlying assumptions and estimates. However, as part of the due diligence review of Allied World in connection with the merger, Allied World’s management prepared and provided to Transatlantic and Goldman Sachs, as well as to Deutsche Bank and Moelis, in connection with their respective evaluation of the fairness of the merger consideration, certain non-public, internal financial forecasts regarding Allied World’s projected future operations for the 2011 through 2015 fiscal years. Allied World has included below a summary of these forecasts for the purpose of providing shareholders and investors access to certain non-public information that was furnished to third parties and such information may not be appropriate for other purposes. These forecasts were also considered by the Allied World board of directors for purposes of evaluating the merger. The Allied World board of directors also considered non-public, financial forecasts prepared by Transatlantic regarding Transatlantic’s anticipated future operations for the 2011 through 2015 fiscal years for purposes of evaluating Transatlantic and the merger. See “The Merger — Certain Transatlantic Prospective Financial Information” beginning on page 76 for more information about the forecasts prepared by Transatlantic.
 
The Allied World internal financial forecasts were not prepared with a view toward public disclosure, nor were they prepared with a view toward compliance with published guidelines of the SEC, SAP or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts or generally accepted accounting principles in the United States. Deloitte & Touche Ltd. has not examined, compiled or performed any procedures with respect to the accompanying prospective financial information and, accordingly, Deloitte & Touche Ltd. does not express an opinion or any other form of assurance with respect thereto. The Deloitte & Touche Ltd. reports incorporated by reference in this joint proxy statement/prospectus relate only to Allied World’s historical financial information. They do not extend to the prospective financial information and should not be read to do so. The summary of these internal financial forecasts included below is not being included to influence your decision whether to vote for the

merger and the transactions contemplated in connection with the merger, but because these internal financial forecasts were provided by Allied World to Transatlantic and Deutsche Bank, Goldman Sachs and Moelis.
 
While presented with numeric specificity, these internal financial forecasts were based on numerous variables and assumptions (including, but not limited to, those related to industry performance and competition and general business, economic, market and financial conditions and additional matters specific to Allied World’s businesses) that are inherently subjective and uncertain and are beyond the control of Allied World’s management. Important factors that may affect actual results and cause these internal financial forecasts to not be achieved include, but are not limited to, risks and uncertainties relating to Allied World’s business (including its ability to achieve strategic goals, objectives and targets over applicable periods), industry performance, general business and economic conditions and other factors described in the “Risk Factors” section of Allied World’s Annual Report on Form 10-K, as updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K all of which are filed with the SEC and incorporated by reference into this joint proxy statement/prospectus. These internal financial forecasts also reflect numerous variables, expectations and assumptions available at the time they were prepared as to certain business decisions that are subject to change. As a result, actual results may differ materially from those contained in these internal financial forecasts. Accordingly, there can be no assurance that the forecasted results summarized below will be realized.
 
The inclusion of a summary of these internal financial forecasts in this joint proxy statement/prospectus should not be regarded as an indication that any of Allied World, Transatlantic or their respective affiliates, advisors or representatives considered these internal financial forecasts to be predictive of actual future events, and these internal financial forecasts should not be relied upon as such nor should the information contained in these internal financial forecasts be considered appropriate for other purposes. None of Allied World, Transatlantic or their respective affiliates, advisors, officers, directors or representatives can give you any assurance that actual results will not differ materially from these internal financial forecasts, and none of them undertakes any obligation to update or otherwise revise or reconcile these internal financial forecasts to reflect circumstances existing after the date these internal financial forecasts were generated or to reflect the occurrence of future events, even in the event that any or all of the assumptions underlying these forecasts are shown to be in error. Since the forecasts cover multiple years, such information by its nature becomes less meaningful and predictive with each successive year. Allied World does not intend to make publicly available any update or other revision to these internal financial forecasts.
 
None of Allied World or its affiliates, advisors, officers, directors or representatives has made or makes any representation to any shareholder or other person regarding Allied World’s ultimate performance compared to the information contained in these internal financial forecasts or that the forecasted results will be achieved. Allied World has made no representation to Transatlantic, in the merger agreement or otherwise, concerning these internal financial forecasts. The below forecasts do not give effect to the merger. Allied World urges all shareholders to review Allied World’s most recent SEC filings for a description of Allied World’s reported financial results.

Transatlantic’s Reasons for the Merger; Recommendations of the Transatlantic Board of Directors
 
In approving the merger agreement and recommending its adoption by Transatlantic stockholders, Transatlantic’s board of directors considered a number of factors and a substantial amount of information


64


Table of Contents

presented by and reviewed and discussed with Transatlantic’s management and legal and financial advisors, and considered numerous factors, including the following:
 
  •  the potential that the merger would create a leading, diversified, specialty focused reinsurance and insurance company with a global reach and a local presence in key markets;
 
  •  management’s belief that the combined company would have a strengthened balance sheet with $8.5 billion of total capital;
 
  •  although no assurance can be given on the reaction of any independent rating agency, management’s belief that the combined company would be able to maintain the financial strength ratings of Transatlantic, especially at S&P, which is a significant asset to Transatlantic’s international business;
 
  •  management’s belief that the combination would diversify risk, which should allow the combined company to weather cyclical conditions and reduce volatility of earnings and deliver more stable results under a wider range of market conditions and economic environments while creating a foundation for future growth;
 
  •  the fact that Transatlantic would gain multiple platforms, including European Union based operating subsidiaries;
 
  •  Transatlantic board of directors’ belief, based upon discussions with Transatlantic’s management and after a thorough review of Transatlantic’s strategic alternatives, that the merger would provide greater value to the Transatlantic stockholders within a shorter timeframe than other potential strategic alternatives available to Transatlantic, including the continued operation of Transatlantic as a standalone company;
 
  •  management’s belief that property catastrophe exposure of the combined company would remain at an optimal level, allowing for future growth;
 
  •  although no assurance can be given that any level of operating and structural synergies would be achieved following the completion of the merger, management’s estimate, consistent with Allied World’s management’s estimate, that the combination of Transatlantic and Allied World would create significant annual synergies on an after tax basis due, in part, to more efficient allocation of capital and cost savings;
 
  •  the fact that, with a Swiss domicile, the combined company should have greater capital flexibility;
 
  •  the fact that Transatlantic stockholders immediately prior to the merger would hold approximately 58% of the voting power of the combined company on a fully diluted basis immediately following completion of the merger;
 
  •  the fixed exchange ratio of 0.88 Allied World shares for each share of Transatlantic common stock, which represented a premium of 16% to the closing price of Transatlantic common stock, based on the closing price of Allied World shares on June 10, 2011 (the last trading day before public announcement of the merger);
 
  •  the complementary nature of Transatlantic’s and Allied World’s businesses;
 
  •  the view of the Transatlantic board of directors that there will be limited integration risk due to the similar cultures of Transatlantic and Allied World with respect to underwriting discipline and risk management, common information technology systems, and limited business overlap;
 
  •  the structure of the transaction as a merger of equals, including the provisions in the merger agreement that:
 
  •  the combined company’s board of directors would initially be comprised of 11 members, six of which would be designated by Transatlantic;
 
  •  the combined company’s board committee assignments would be split evenly between designees from the Transatlantic board of directors and designees from the Allied World board of directors;


65


Table of Contents

 
  •  Mr. Press would initially be the non-executive chairman of the board of directors of the combined company;
 
  •  Mr. Sapnar would be appointed as the President and Chief Executive Officer of Global Reinsurance of the combined company; and
 
  •  the remaining members of management of the combined company would be drawn from the two companies on a fair and equitable basis with a roughly equal number of people coming from each;
 
  •  the expectation of the Transatlantic board of directors that the integration of the two companies will be completed in a timely and efficient manner with minimal disruption to customers and employees;
 
  •  the fact that the combined company would have a highly experienced management team with extensive industry experience in the most significant facets of the insurance and reinsurance industry;
 
  •  the Transatlantic board of directors’ knowledge of Transatlantic’s business, financial condition, results of operations and prospects as a standalone company, as well as Allied World’s business, financial condition, results of operations and prospects, taking into account the results of Transatlantic’s due diligence review of Allied World;
 
  •  the strong commitment on the part of both parties to complete the merger pursuant to their respective obligations under the terms of the merger agreement;
 
  •  the fact that the merger agreement allows the Transatlantic board of directors to change or withdraw its recommendation regarding the merger proposal if a superior proposal is received from a third party or in response to certain material developments or changes in circumstances, if in either case the Transatlantic board of directors determines that a failure to change its recommendation would result in a breach of its fiduciary duties under applicable law, subject to the payment of a termination fee upon termination under certain circumstances;
 
  •  the Transatlantic board of directors’ belief, after consultation with its internal and outside legal counsel, that the transactions are likely to receive necessary regulatory approvals in a relatively timely manner without material adverse conditions, which increases the likelihood the transactions will be consummated; and
 
  •  the financial analyses presented by Moelis to the Transatlantic board of directors described below under “— Opinion of Transatlantic’s Financial Advisor” and the opinion of Moelis, delivered orally at the Transatlantic board of directors’ meeting on June 12, 2011, and subsequently confirmed in writing by delivery of a written opinion dated the same date, to the effect that, as of that date and based upon and subject to the assumptions, procedures, factors, qualifications and limitations set forth in such written opinion, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to the holders of Transatlantic common stock. See “— Opinion of Transatlantic’s Financial Advisor.”
 
The Transatlantic board of directors also weighed the factors described above against a number of risks and other factors identified in its deliberations as weighing negatively against the merger:
 
  •  the restrictions on the conduct of Transatlantic’s business during the period between execution of the merger agreement and the consummation of the merger;
 
  •  the substantial costs to be incurred in connection with the merger, including the substantial cash and other costs of integrating the businesses of Transatlantic and Allied World, as well as the transaction expenses arising from the merger;
 
  •  the fact that forecasts of future results of operations and synergies are necessarily estimates based on assumptions, and that for these and other reasons there is a risk of not capturing anticipated operational synergies and cost savings between Transatlantic and Allied World and the risk that other anticipated benefits might not be realized;
 
  •  the potential effect of the merger on Transatlantic’s business and relationships with employees, customers, suppliers, brokers, regulators and the communities in which it operates;


66


Table of Contents

 
  •  the fact that the transaction would be taxable to Transatlantic’s stockholders that are U.S. holders for U.S. federal income tax purposes;
 
  •  the risk that governmental entities may not approve the merger or may impose conditions on Transatlantic or Allied World in order to gain approval for the merger that may adversely impact the ability of the combined company to realize the synergies that are projected to occur in connection with the merger;
 
  •  the possibility that the merger may not be completed, or that completion may be unduly delayed, for reasons beyond the control of Transatlantic and/or Allied World;
 
  •  the potential that the termination fee provisions of the merger agreement could have the effect of discouraging a bona fide alternative acquisition proposal for Transatlantic;
 
  •  the merger agreement’s requirement that the Transatlantic board of directors call and hold a meeting of Transatlantic stockholders to vote upon the merger, regardless of whether or not the Transatlantic board of directors has withdrawn or adversely modified its recommendation to the Transatlantic stockholders regarding the merger in response to a superior proposal or certain material developments or changes in circumstances;
 
  •  potential withholding taxes associated with reallocating capital among different jurisdictions;
 
  •  the risk that Allied World’s loss reserves may prove to be inadequate;
 
  •  the challenges of combining Transatlantic’s business with Allied World’s business, including technical, accounting and other challenges, and the risk of diverting management resources for an extended period of time to accomplish this combination;
 
  •  the loss of key personnel could delay or prevent the combined entity from fully implementing its business strategy and, consequently, significantly and negatively affect its business;
 
  •  risks of the type and nature described in the section entitled “Risk Factors” beginning on page 22 and “Special Note Regarding Forward-Looking Statements” beginning on page 21; and
 
  •  the fact that Transatlantic’s directors and executive officers have interests in the merger that may be different from, or in addition to, those of Transatlantic stockholders. See the section entitled “The Merger — Interests of Transatlantic’s Directors and Executive Officers in the Merger” beginning on page 78.
 
This discussion of the information and factors considered by the Transatlantic board of directors in reaching its conclusions and recommendation includes the material factors considered by the Transatlantic board of directors, but is not intended to be exhaustive. In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the Transatlantic board of directors did not find it practicable, and did not attempt, to quantify, rank or assign any relative or specific weights to the various factors that it considered in reaching its determination to approve the merger agreement and to recommend that Transatlantic stockholders vote in favor of the adoption of the merger agreement proposal. The Transatlantic board of directors conducted an overall analysis of the factors described above, including through discussions with, and questioning of, Transatlantic’s management and outside legal and financial advisors regarding certain of the matters described above. In considering the factors described above, individual members of the Transatlantic board of directors may have given differing weights to different factors.
 
The Transatlantic board of directors unanimously approved the merger agreement and determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and in the best interests of Transatlantic and its stockholders. The Transatlantic board of directors unanimously recommends that Transatlantic stockholders vote “FOR” the adoption of the merger agreement proposal.

Opinion of Transatlantic’s Financial Advisor
 
Opinion of Moelis & Company LLC
 
In connection with the merger, on June 12, 2011, Moelis delivered its oral opinion, which was subsequently confirmed in writing, that based upon and subject to the conditions and limitations set forth in its written opinion, as of June 12, 2011, the exchange ratio set forth in the merger agreement was fair, from a financial point of view, to the holders of Transatlantic common stock.
 
The full text of Moelis’ written opinion, dated June 12, 2011, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached to this joint proxy statement/prospectus as Annex C and is incorporated into this joint proxy statement/prospectus by reference. Holders of Transatlantic common stock are urged to read Moelis’ written opinion and this section carefully and in their entirety. The following summary describes the material analyses underlying Moelis’ opinion, but does not purport to be a complete description of the analyses performed by Moelis in connection with its opinion. Moelis’ opinion is limited solely to the fairness, from a financial point of view, of the exchange ratio set forth in the merger agreement to the holders of Transatlantic common stock as of the date of the opinion and does not address Transatlantic’s underlying business decision to effect the merger or the relative merits of the merger as compared to any alternative business strategies or transactions that might be available to Transatlantic. Moelis’ opinion does not constitute a recommendation to any stockholder of Transatlantic as to how such stockholder should vote with respect to the merger or any other matter. Moelis’ opinion was approved by a Moelis fairness opinion committee.
 
In arriving at its opinion, Moelis, among other things:
 
  •  reviewed certain publicly available business and financial information relating to Transatlantic and Allied World that Moelis deemed relevant;
 
  •  reviewed certain internal information relating to the business, including financial forecasts, earnings, cash flow, assets, liabilities and prospects of Transatlantic, furnished to Moelis by Transatlantic;
 
  •  reviewed certain internal information relating to the business, including financial forecasts, earnings, cash flow, assets, liabilities and prospects of Allied World, furnished to Moelis by Allied World;
 
  •  conducted discussions with members of senior management and representatives of Transatlantic and Allied World concerning the matters described in the foregoing, as well as their respective businesses and prospects before and after giving effect to the merger;
 
  •  reviewed publicly available financial and stock market data, including valuation multiples, for Transatlantic and Allied World and compared them with those of certain other companies in lines of business that Moelis deemed relevant;
 
  •  compared the proposed financial terms of the merger with the financial terms of certain other transactions that Moelis deemed relevant;
 
  •  reviewed a draft of the merger agreement, dated June 11, 2011;
 
  •  participated in certain discussions and negotiations among representatives of Transatlantic and Allied World and their financial and legal advisors; and
 
  •  conducted such other financial studies and analyses and took into account such other information as Moelis deemed appropriate.
 
In connection with Moelis’ review, it did not assume any responsibility for independent verification of any of the financial, legal, regulatory, tax, accounting and other information supplied to, discussed with, or reviewed by Moelis for the purpose of its opinion and has, with the consent of the board of directors of Transatlantic, relied on such information being complete and accurate in all material respects. In addition, with the consent of the Transatlantic board of directors, Moelis did not make any independent evaluation or appraisal of any of the assets or liabilities (contingent, derivative, off-balance-sheet, or otherwise) of


68


Table of Contents

Transatlantic or Allied World, nor was Moelis furnished with any such evaluation or appraisal. Moelis is not an expert in the evaluation of reserves for insurance losses and loss adjustment expenses, and did not make an independent evaluation of the adequacy of reserves of Transatlantic or Allied World. In that regard, Moelis did not make an analysis of, and expressed no opinion as to, the adequacy of the loss and loss adjustment expense reserves of, the value of redundant reserves to, or the ability to achieve reserve releases by, Transatlantic or Allied World. Moelis was not requested, and did not undertake, to make any independent valuation of Transatlantic’s pending arbitration matters concerning AIG and certain of its subsidiaries, and for purposes of Moelis’ analysis, at the direction of the Transatlantic board of directors, Moelis assumed that Transatlantic will obtain a recovery in the amount and at the time estimated by Transatlantic management. In addition, with respect to the forecasted financial information referred to above, Moelis assumed, at the direction of the Transatlantic board of directors, that such financial information was reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Transatlantic and Allied World as to the future performance of their respective companies and that such future financial results will be achieved at the times and in the amounts projected by management of Transatlantic and Allied World.
 
Moelis’ opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to Moelis as of, the date thereof. Moelis assumed, with the consent of the Transatlantic board of directors, that all governmental, regulatory or other consents and approvals necessary for the completion of the merger will be obtained without the imposition of any delay, limitation, restriction, divestiture or condition that would have an adverse effect on Transatlantic or Allied World or on the expected benefits of the merger. Subsequent developments may affect Moelis’ opinion but Moelis does not have any obligation to update, revise or reaffirm its opinion. Moelis’ opinion does not constitute legal, tax or accounting advice.
 
The following is a summary of the material financial analyses presented by representatives of Moelis to the Transatlantic board of directors at its meeting held on June 12, 2011, in connection with the delivery of the oral opinion at that meeting and Moelis’ subsequent written opinion.
 
Some of the summaries of financial analyses below include information presented in tabular format. In order to fully understand Moelis’ analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the analyses. Considering the data described below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Moelis’ analyses.
 
The analyses performed by Moelis include analyses based upon forecasts of future results, which results might be significantly more or less favorable than those upon which Moelis’ analyses were based. The analyses do not purport to be appraisals or to reflect the prices at which Transatlantic common stock might trade at any time following the announcement of the merger. Because the analyses are inherently subject to uncertainty, being based upon numerous factors and events, including, without limitation, factors relating to general economic and competitive conditions beyond the control of the parties or their respective advisors, neither Moelis nor any other person assumes responsibility if future results or actual values are materially different from those contemplated below.
 
Dividend Discount Model Analysis
 
Moelis conducted a dividend discount model analysis for Transatlantic and Allied World. A dividend discount model analysis is a method of evaluating the equity value of a company using estimates of the future dividends to stockholders generated by a company and taking into consideration the time value of money with respect to those future dividends by calculating their “present value.” “Present value” refers to the current value of future dividends to stockholders paid by such company and is obtained by discounting those future dividends back to the present using a discount rate that takes into account macro-economic assumptions, estimates of risk, the opportunity cost of capital, and other appropriate factors.
 
Based on estimates provided by Transatlantic management as to the maximum amount of possible dividends that can be paid out by Transatlantic and estimates provided by Allied World management as to the maximum amount of possible dividends that can be paid out by Allied World, in each case, during fiscal years

(“FYs”) 2011 through 2015 (assuming no capital is returned through share repurchases and, in the case of Transatlantic, adjusted for its first quarter 2011 dividend and the potential tax-effected full recovery from pending arbitration with American International Group, Inc. and certain of its subsidiaries and, in the case of Allied World, adjusted for its first quarter 2011 share repurchase and purchase of founder warrants), Moelis discounted the applicable amounts to present values using a range of discount rates from 8.8% to 10.8% for Transatlantic, and 9.3% to 11.3% for Allied World, both of which were chosen by Moelis based upon an analysis of the cost of equity of Transatlantic and Allied World. Moelis also calculated a range of terminal values for Transatlantic and Allied World at the end of the 5-year period ending FY 2015 by applying, in the case of Transatlantic, a terminal book value multiple ranging from 0.70x to 1.00x and Transatlantic’s projected FY 2015 book value as provided by Transatlantic management, and, in the case of Allied World, a terminal book value multiple ranging from 0.80x to 1.10x and Allied World’s projected FY 2015 book value as provided by Allied World management, and discounting the terminal value using a range of discount rates from 8.8% to 10.8% for Transatlantic, and 9.3% to 11.3% for Allied World. “Terminal value” refers to the capitalized value of all future dividends to stockholders paid by a company for periods beyond the final forecast period.
 
Using, in the case of Transatlantic, a terminal book value multiple ranging from 0.75x to 0.95x and Transatlantic’s projected FY 2015 book value as provided by Transatlantic management, and, in the case of Allied World, a terminal book value multiple ranging from 0.85x to 1.05x and Allied World’s projected FY 2015 book value as provided by Allied World management, and discounting the maximum amounts of possible dividends that can be paid out by each of Transatlantic and Allied World, in each case, during FYs 2011 through 2015 and the respective terminal values, using a range of discount rates from 9.3% to 10.3% for Transatlantic, and 9.8% to 10.8% for Allied World, Moelis calculated a low and high implied equity value per share for Transatlantic of $59.00 per share and $70.75 per share and for Allied World of $65.46 per share and $78.67 per share.
 
Moelis then calculated (1) the ratio of the lowest implied equity value per share for Transatlantic to the highest implied equity value per share for Allied World, and (2) the ratio of the highest implied equity value per share for Transatlantic to the lowest implied equity value per share for Allied World to derive an implied exchange ratio range as set forth below:

Selected Public Companies Analysis
 
Moelis performed a selected public companies analysis by comparing certain financial information of Transatlantic and Allied World with corresponding financial information of selected public companies. Although none of the selected companies is directly comparable to Transatlantic or Allied World, Moelis selected reinsurance and/or insurance companies with similar operations to Transatlantic and Allied World, and then used publicly available information regarding these companies to conduct a selected public companies analysis. The companies Moelis selected are as follows:
 
  •  ACE Limited;
 
  •  Alterra Capital Holdings Limited;
 
  •  Arch Capital Group Ltd.;
 
  •  Aspen Insurance Holdings Limited;
 
  •  AXIS Capital Holdings Limited;
 
  •  Endurance Specialty Holdings Ltd.;

  •  EverestRe Group Ltd.;
 
  •  Flagstone Reinsurance Holdings Limited;
 
  •  Montpelier Re Holdings Ltd.;
 
  •  PartnerRe Ltd.;
 
  •  Platinum Underwriters Holdings, Ltd.;
 
  •  RenaissanceRe Holdings Ltd.;
 
  •  Validus Holdings, Ltd.; and
 
  •  XL Capital Ltd.
 
From such list of 14 companies, Moelis then selected those that predominately write reinsurance (excluding those that write property casualty reinsurance) as Transatlantic’s core selected companies, which are the following:
 
  •  EverestRe Group Ltd.;
 
  •  PartnerRe Ltd.; and
 
  •  Platinum Underwriters Holdings, Ltd.
 
From the list of 14 companies, Moelis selected those that write both direct insurance and reinsurance as Allied World’s core selected companies, which are the following:
 
  •  ACE Limited;
 
  •  Alterra Capital Holdings Limited;
 
  •  Arch Capital Group Ltd.;
 
  •  Aspen Insurance Holdings Limited;
 
  •  AXIS Capital Holdings Limited;
 
  •  Endurance Specialty Holdings Ltd; and
 
  •  XL Capital Ltd.
 
As part of its selected public companies analysis, Moelis calculated and analyzed each selected company’s price-to-earnings (P/E) ratio, price-to-book value (P/BV) and price-to-tangible-book value (P/TBV) multiples. Moelis noted that given the significant catastrophic events that occurred during the first quarter of 2011, the use of FY 2011 projected earnings would not provide an accurate representation of the earnings of Transatlantic or Allied World going forward. Thus, for purposes of its analysis, Moelis used FY 2012 projected earnings per share for the selected public companies based on consensus analyst estimates compiled by FactSet, as well as March 31, 2011 amounts for purposes of calculating book values and tangible book values.

Based on its analysis of the foregoing core selected public companies for Transatlantic, Moelis selected the following valuation multiple ranges: 7.0x to 8.5x for equity value as a multiple of Transatlantic’s projected FY 2012 operating income as provided by Transatlantic management, 0.75x to 0.85x for equity value as a multiple of Transatlantic’s March 31, 2011 book value and 0.75x to 1.00x for equity value as a multiple of its March 31, 2011 tangible book value. Moelis applied the selected ranges to the relevant statistics for Transatlantic using Transatlantic’s projected FY 2012 operating income as provided by Transatlantic management and March 31, 2011 book and tangible book values and calculated an implied range of Transatlantic common stock prices on a fully diluted basis of $50.06 to $60.79 based on projected FY 2012 operating income as provided by Transatlantic management, of $47.93 to $54.33 based on its March 31, 2011 book value and of $47.74 to $63.65 based on its March 31, 2011 tangible book value.
 
Based on its analysis of the foregoing core selected public companies for Allied World, Moelis selected the following valuation multiple ranges: 7.5x to 11.0x for its equity value as a multiple of Allied World’s projected FY 2012 operating income as provided by Allied World management, 0.70x to 1.15x for its equity value as a multiple of its March 31, 2011 book value and 0.70x to 1.20x for its equity value as a multiple of Allied World’s March 31, 2011 tangible book value. Moelis applied the selected ranges to the relevant statistics for Allied World using Allied World’s projected FY 2012 operating income as provided by Allied World management and March 31, 2011 book and tangible book values and calculated an implied range of Allied World share prices on a fully diluted basis of $53.58 to $78.59 based on projected FY 2012 operating income as provided by Allied World management, of $52.05 to $85.51 based on its March 31, 2011 book value and of $46.32 to $79.41 based on its March 31, 2011 tangible book value.
 
Based on the foregoing applicable valuation ranges for each of Transatlantic and Allied World, Moelis then calculated the ranges of implied exchange ratio set forth below:
 
                 
    Low     High  
 
FY 2012 Operating Income
    0.637       1.134

Selected Transactions Analysis
 
Moelis compared selected financial and transaction metrics of the merger with similar data (where available) of selected transactions in the reinsurance sector since 1999 valued in excess of $1.0 billion, which were the following:
 
  •  Max Capital Group Ltd.’s merger with Harbor Point, Ltd. announced on March 3, 2010;
 
  •  Validus Holdings Ltd.’s merger with IPC Holdings Ltd. announced on July 9, 2009;
 
  •  PartnerRe Holdings Ltd.’s acquisition of PARIS Re Holdings Ltd. announced on July 4, 2009; and
 
  •  SCOR Holding (Switzerland) Ltd.’s acquisition of Converium Holding AG announced on May 10, 2007.
 
For each such transaction, Moelis calculated valuation multiples based on information that was publicly available, focusing on P/BV and P/TBV multiples (in each case, based on the book value and tangible book value reflected on the financial statements of the applicable target company prepared pursuant to GAAP), to evaluate such transactions. Moelis noted that given the significant catastrophic events that occurred during the first quarter of 2011, a focus on valuation multiples based on last-twelve months net income would not provide an accurate comparison. Thus, for purposes of this analysis, Moelis focused on P/BV and P/TBV valuation multiples. The following table presents the results of such calculations:
 
                 
    P/BV     P/TBV  
 
Max Capital/Harbor Point
    0.79 x     0.92 x
Validus/IPC
    0.85 x     0.85 x
Partner Re/PARIS Re
    0.97 x     1.09 x
SCOR/Converium
    1.69 x     1.42 x
 
Based on its analysis of the foregoing selected transactions, Moelis selected a range of 0.80x to 0.95x for equity value as a multiple of P/B and a range of 0.85x to 1.05x for equity value as a multiple of P/TBV. Moelis applied the selected ranges to the relevant statistics for Transatlantic using Transatlantic’s March 31, 2011 book and tangible book values and calculated an implied range of Transatlantic common stock prices on a fully diluted basis of $51.13 to $60.72 and of $54.11 to $66.84, respectively. Moelis applied the selected ranges to the relevant statistics for Allied World using Allied World’s March 31, 2011 book and tangible book values and calculated an implied range of Allied World share prices on a fully diluted basis of $59.48 to $70.64 and $56.25 to $69.49, respectively.
 
Based on the foregoing applicable valuation ranges for each of Transatlantic and Allied World, Moelis then calculated the following ranges of implied exchange ratio as set forth below:
 
                 
    Low     High  
 
Book Value (as of 3/31/11)
    0.724       1.021  
Tangible Book Value (as of 3/31/11)
    0.779       1.188  
 
52-Week Trading Range
 
Moelis reviewed the trading range of Transatlantic common stock and Allied World shares for the 52-week period ending June 10, 2011, which ranged from $43.90 to $54.08 in the case of Transatlantic and from $44.27 to $65.70 in the case of Allied World. Based on the foregoing 52-week trading ranges, Moelis then calculated a range of implied exchange ratio of 0.668 to 1.222.
 
Contribution Analysis
 
Moelis calculated the hypothetical relative contributions of Transatlantic and Allied World to a combined company in terms of:
 
  •  implied equity ownership as a result of the merger (based on fully diluted shares outstanding) and market capitalization (on a fully diluted basis based on closing share price as of June 10, 2011);

  •  FY 2010 net premiums written;
 
  •  FY 2010 and projected FYs 2011 and 2012 operating income as provided by Transatlantic and Allied World management respectively; and
 
  •  cash and investments, net policy reserves, equity (including accumulated other comprehensive income (“AOCI”)), and tangible equity (including AOCI), in each case, as per the applicable company’s March 31, 2011 balance sheet.

The preparation of a fairness opinion is a complex analytical process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Moelis’ opinion. In arriving at its fairness determination, Moelis considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis. Rather, Moelis made its fairness determination on the basis of its experience and professional judgment after considering the results of all of its analyses.
 
No company or transaction used in the analyses described above for purposes of comparison is directly comparable to Transatlantic, Allied World or the merger. In addition, such analyses do not purport to be appraisals, nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by such analyses. Because the analyses described above are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, neither Transatlantic, nor Moelis or any other person assumes responsibility if future results are materially different from those forecast.
 
The exchange ratio set forth in the merger agreement was determined through arms’ length negotiations between Transatlantic and Allied World and was approved by the Transatlantic board of directors. The decision by the Transatlantic board of directors to approve, adopt and authorize the merger was solely that of the Transatlantic board of directors. Representatives of Moelis provided advice to Transatlantic during these negotiations. Moelis did not, however, recommend any specific exchange ratio to Transatlantic or the Transatlantic board of directors, or that any specific amount or type of consideration constituted the only appropriate consideration for the merger.
 
The Moelis opinion and financial analyses, taken together, represented only one of many factors considered by the Transatlantic board of directors in its evaluation of the merger and was not determinative of the views of the Transatlantic board of directors or Transatlantic’s management with respect to the merger, the


74


Table of Contents

exchange ratio set forth in the merger agreement or whether the Transatlantic board of directors would have been willing to agree to different consideration.
 
Moelis’ opinion was prepared for the use and benefit of the Transatlantic board of directors in its evaluation of the merger. Moelis was not asked to address, and its opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of Transatlantic, other than the holders of Transatlantic common stock. In addition, Moelis’ opinion does not express any opinion as to the fairness of the amount or nature of any compensation to be received by any of Transatlantic’s officers, directors or employees, or any class of such persons, relative to the exchange ratio set forth in the merger agreement. At the direction of the Transatlantic board of directors, Moelis was not asked to, nor did it, offer any opinion as to the material terms of the merger agreement or the form of the merger. Moelis expressed no opinion as to what the value of Allied World shares would be when issued pursuant to the merger or the prices at which such Allied World shares would trade in the future. In rendering its opinion, Moelis assumed, with the consent of the Transatlantic board of directors, that the final executed form of the merger agreement would not differ in any material respect from the draft that Moelis examined, that the representations and warranties of each of Transatlantic and Allied World are true and correct, that Transatlantic and Allied World would perform all of the covenants and agreements required to be performed by each of them, and that all conditions to the completion of the merger will be satisfied without waiver thereof and that the merger will be consummated in a timely manner in accordance with the terms of the merger agreement, without any modifications or amendments thereto or any adjustment of the exchange ratio set forth in the merger agreement.
 
Pursuant to the terms of Moelis’ engagement as financial advisor to the Transatlantic board of directors, Moelis has earned a fee of $2.5 million for rendering its opinion, payable upon delivery of its opinion, regardless of whether the merger is consummated. Moelis will also be entitled to receive a one-time transaction fee of $1 million if the merger is consummated. Solely at the discretion of Transatlantic, Moelis may receive an additional one-time fee of $1.5 million, payable upon completion of the merger. Moelis’ engagement letter with Transatlantic provides that if Moelis is requested by Transatlantic to deliver an additional opinion, Moelis shall be entitled to an additional $0.5 million upon delivery of such additional opinion, which fee shall be creditable towards the $1.0 million transaction fee referenced above. In addition, Transatlantic has agreed to reimburse Moelis for all reasonable and documented out-of-pocket expenses incurred in connection with its rendering of the opinion, including the expense of legal counsel, up to a specified maximum amount that is not to be exceeded without the prior written consent of Transatlantic (which is not to be unreasonably withheld). Transatlantic has also agreed to indemnify Moelis for certain liabilities arising out of its engagement.
 
Pursuant to the terms of a prior engagement letter between Moelis and the Special Committee entered into in February 2010, pursuant to which Moelis received a quarterly retainer fee and customary reimbursement for expenses, Moelis was engaged to (i) undertake (in consultation with members of Transatlantic management and the Special Committee) a customary business and financial analysis of Transatlantic and (ii) meet with the Special Committee to discuss strategic opportunities for Transatlantic and their financial implications, in each case, to the extent requested by the Special Committee. Moelis may provide investment banking services to Transatlantic, Allied World and their respective affiliates and/or successors in the future for which Moelis would expect to receive compensation. In the ordinary course of business, Moelis’ affiliates may trade securities of Transatlantic or Allied World for their own accounts and the accounts of their customers and, accordingly, may at any time hold a long or short position in such securities.
 
The Transatlantic board of directors selected Moelis as its financial advisor in connection with the merger because, among other things, Moelis has substantial experience in transactions similar to the merger. Moelis is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, strategic transactions, corporate restructurings, and valuations for corporate and other purposes.

Certain Information Regarding Transatlantic’s Financial Advisor — Goldman Sachs
 
Goldman Sachs and its affiliates are engaged in investment banking and financial advisory services, commercial banking, securities trading, investment management, principal investment, financial planning, benefits counseling, risk management, hedging, financing, brokerage activities and other financial and non-financial activities and services for various persons and entities. In the ordinary course of these activities and services, Goldman Sachs and its affiliates may at any time make or hold long or short positions and investments, as well as actively trade or effect transactions, in the equity, debt and other securities (or related derivative securities) and financial instruments (including bank loans and other obligations) of Transatlantic, Allied World and any of their respective affiliates and third parties or any currency or commodity that may be involved in the transaction contemplated by the merger agreement for their own account and for the accounts of their customers. Goldman Sachs acted as financial advisor to Transatlantic in connection with, and participated in certain of the negotiations leading to, the merger. Goldman Sachs has provided certain investment banking services to Transatlantic and its affiliates from time to time for which Goldman Sachs’ Investment Banking Division has received, and may receive, compensation, including acting as a joint bookrunning manager in connection with the secondary public offering of 29.9 million shares of Transatlantic common stock by American International Group, Inc. and its indirect subsidiary, American Home Assurance Company, in June 2009, as an underwriter in connection with the public offering of Transatlantic’s 8.00% Senior Notes due 2039 ($350 million aggregate principal amount) in November 2009 and as an underwriter in connection with the secondary public offering of 8.5 million shares of Transatlantic common stock by American Home Assurance Company in March 2010. Goldman Sachs may also in the future provide investment banking services to Transatlantic, Allied World and their respective affiliates for which Goldman Sachs’ Investment Banking Division may receive compensation. Affiliates of Goldman Sachs owned Allied World shares and warrants to acquire additional Allied World shares until November 2010, when Allied World repurchased all Allied World shares and warrants then held by such Goldman Sachs affiliates.
 
The Transatlantic board of directors selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement, dated June 9, 2011, Transatlantic engaged Goldman Sachs to act as its financial advisor in connection with the merger. Pursuant to the terms of this engagement letter, Transatlantic has agreed to pay Goldman Sachs a transaction fee, all of which is contingent upon consummation of the merger, in an amount that will depend on the aggregate consideration in the merger, which in turn will depend on the average trading price of Allied World shares during the five days preceding the stockholder vote relating to the merger. For illustrative purposes, based on the average trading price of Allied World shares from June 13, 2011 through June 17, 2011, this transaction fee would have equaled approximately $20 million. In addition, Transatlantic has agreed to reimburse Goldman Sachs for its expenses arising, and to indemnify Goldman Sachs and related persons against certain liabilities that may arise out of its engagement.
 
Certain Transatlantic Prospective Financial Information
 
Transatlantic does not, as a matter of course, make public long-term forecasts as to future performance or other prospective financial information beyond the current fiscal year, and Transatlantic is especially wary of making forecasts or projections for extended periods due to the unpredictability of the underlying assumptions and estimates. However, as part of the due diligence review of Transatlantic in connection with the merger, Transatlantic’s management prepared and provided to Allied World and Goldman Sachs, as well as to Deutsche Bank and Moelis in connection with their respective evaluations of the fairness of the merger consideration, certain non-public, internal financial forecasts regarding Transatlantic’s projected future operations for fiscal years 2011 through 2015. Transatlantic has included below a summary of these forecasts for the purpose of providing stockholders and investors access to certain non-public information that was furnished to third parties and such information may not be appropriate for other purposes. These forecasts were also considered by the Transatlantic board of directors for purposes of evaluating the merger. The Transatlantic board of directors also considered non-public, financial forecasts prepared by Allied World regarding Allied World’s projected future operations for fiscal years 2011 through 2015 for purposes of evaluating Allied World

and the merger. See the section entitled “The Merger — Certain Allied World Prospective Financial Information” beginning on page 63 for more information about the forecasts prepared by Allied World.
 
These internal financial forecasts were not prepared with a view toward public disclosure, nor were they prepared with a view toward compliance with published guidelines of the SEC, GAAP, SAP, IFRS or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentations of financial forecasts. The prospective financial information included in this joint proxy statement/prospectus has been prepared by, and is the responsibility of, Transatlantic’s management. PricewaterhouseCoopers LLP, Transatlantic’s independent auditor, has neither examined, compiled nor performed any procedures with respect to the accompanying prospective financial information and, accordingly, PricewaterhouseCoopers LLP does not express an opinion or any other form of assurance with respect thereto. The PricewaterhouseCoopers LLP report incorporated by reference in this joint proxy statement/prospectus relates to Transatlantic’s historical financial information. It does not extend to the prospective financial information and should not be read to do so. The summary of these internal financial forecasts included below is not being included to influence your decision whether to vote for the merger and the transactions contemplated in connection with the merger, but instead because these internal financial forecasts were provided by Transatlantic to Allied World, Goldman Sachs, Moelis and Deutsche Bank.
 
While presented with numeric specificity, these internal financial forecasts were based on numerous variables and assumptions (including, but not limited to, those related to industry performance and competition and general business, economic, market and financial conditions and additional matters specific to Transatlantic’s businesses) that are inherently subjective and uncertain and are beyond the control of Transatlantic’s management. Important factors that may affect actual results and cause these internal financial forecasts to not be achieved include, but are not limited to, risks and uncertainties relating to Transatlantic’s business (including its ability to achieve strategic goals, objectives and targets over applicable periods), industry performance, general business and economic conditions, the occurrence of unpredictable catastrophe events and other factors described in the sections entitled “Special Note Regarding Forward-Looking Statements” and “Risk Factors,” beginning on page 21 and page 22, respectively. These internal financial forecasts also reflect numerous variables, expectations and assumptions available at the time they were prepared as to certain business decisions that are subject to change. As a result, actual results may differ materially from those contained in these internal financial forecasts. Accordingly, there can be no assurance that the forecasted results summarized below will be realized.
 
The inclusion of a summary of these internal financial forecasts in this joint proxy statement/prospectus should not be regarded as an indication that any of Transatlantic, Allied World or their respective affiliates, advisors or representatives considered these internal financial forecasts to be predictive of actual future events, and these internal financial forecasts should not be relied upon as such nor should the information contained in these internal financial forecasts be considered appropriate for other purposes. None of Transatlantic, Allied World or their respective affiliates, advisors, officers, directors, partners or representatives can give you any assurance that actual results will not differ materially from these internal financial forecasts, and none of them undertakes any obligation to update or otherwise revise or reconcile these internal financial forecasts to reflect circumstances existing after the date these internal financial forecasts were generated or to reflect the occurrence of future events, even in the event that any or all of the assumptions underlying these forecasts are shown to be in error. Since the forecasts cover multiple years, such information by its nature becomes less meaningful and accurate with each successive year. Transatlantic does not intend to make publicly available any update or other revision to these internal financial forecasts. None of Transatlantic or its affiliates, advisors, officers, directors or representatives has made or makes any representation to any stockholder, investor or other person regarding Transatlantic’s ultimate performance compared to the information contained in these internal financial forecasts or that the forecasted results will be achieved.
 
None of Transatlantic, or its affiliates, advisors, officers, directors or representatives have made any representation to any stockholder, Allied World or any other person, in the merger agreement or otherwise, concerning these internal financial forecasts. The below forecasts do not give effect to the merger. Transatlantic urges all stockholders to review Transatlantic’s most recent SEC filings for a description of Transatlantic’s reported financial results.

Interests of Allied World’s Directors and Executive Officers in the Merger
 
In considering the recommendation of the board of directors of Allied World that you vote to approve the issuance of shares of Allied World in connection with the merger, the adoption of Allied World’s amended and restated Articles of Association, and the election of directors, you should be aware that Allied World’s directors and executive officers have financial interests in the merger that may be different from, or in addition to, those of Allied World shareholders generally. The board of directors of Allied World was aware of and considered these potential interests, among other matters, in evaluating and negotiating the merger agreement and the merger and in recommending to you that you approve the issuance of Allied World shares in connection with the merger and the adoption of Allied World’s amended and restated Articles of Association.
 
Each of Allied World’s executive officers is a party to an employment agreement that would provide for the acceleration of certain payments and benefits upon the consummation of the merger. Allied World is in the process of implementing a new retention program pursuant to which certain of its executive officers would waive all or a portion of the accelerated payments and benefits in exchange for the new retention arrangement.
 
Allied World does not expect a significant reduction in workforce as a result of the merger, subject to the discussion above regarding the potential difficulty of retaining key management personnel in the section entitled “Risk Factors — Risk Factors Relating to the Merger.”
 
As described in further detail below under the heading “The Merger — Board of Directors and Management Following the Merger,” certain of Allied World’s executive officers and members of the Allied World board of directors will continue to serve as officers or directors of the combined company upon completion of the merger. Specifically, Scott A. Carmilani will serve as the President and Chief Executive Officer of the combined company unless he is not the Chief Executive Officer of Allied World immediately prior to the effective time of the merger.
 
Interests of Transatlantic’s Directors and Executive Officers in the Merger
 
In considering the recommendation of the board of directors of Transatlantic to vote to adopt the merger agreement, you should be aware that Transatlantic’s directors and executive officers have financial interests in the merger that may be in addition to, or different from, the interests of Transatlantic stockholders generally. The board of directors of Transatlantic was aware of and considered these potential interests, among other matters, in evaluating and negotiating the merger agreement and in recommending to you that you approve the merger and the other transactions contemplated by the merger.

As detailed below under “— Board of Directors and Management Following the Merger,” certain of Transatlantic’s executive officers and members of the Transatlantic board of directors will continue to serve as officers or directors of the combined company upon completion of the merger. Specifically, Richard S. Press, the current non-executive chairman of the board of directors of Transatlantic, will be the non-executive chairman of the board of directors of the combined company following the merger. Michael C. Sapnar will be appointed to serve as President and Chief Executive Officer of Global Reinsurance of the combined company.
 
Transatlantic does not expect a significant reduction in workforce as a result of the merger, subject to the discussion above regarding the potential difficulty of retaining key management personnel in the section entitled “Risk Factors — Relating to the Merger.”
 
On June 30, 2011, the Compensation Committee (the “Transatlantic Compensation Committee”) of the Transatlantic board of directors approved the form of retention agreements (the “Retention Agreements,” and each, a “Retention Agreement”) that will be offered to certain executives of Transatlantic, including Steven S. Skalicky, Paul A. Bonny, and Javier E. Vijil, each a named executive officer of Transatlantic. Each of the Retention Agreements has a term beginning on the date of execution and ending on the earlier of December 31, 2013 or a mutually agreed upon termination date by the executive and Transatlantic. The Retention Agreements will remain effective whether or not the merger closes.
 
Each of the Retention Agreements generally provides that until December 31, 2012, the executive’s base salary level, target bonus amount, target fair value of equity awards and other benefits included in the executive’s total compensation will not be reduced below the levels in effect prior to the merger. Each of the Retention Agreements also provides for a grant of restricted stock unit awards (“RSUs”), or in the event that there are not enough share reserves, phantom stock awards (together with the RSUs, the “Retention Grant”), immediately prior to the merger (or at a date chosen by the Transatlantic board of directors in its discretion, if the closing of the merger does not occur), pursuant to Transatlantic’s 2009 Long Term Equity Incentive Plan (but only in the case of the RSUs), consisting of that number of shares of Transatlantic common stock equal in value to $1,500,000 for each of Messrs. Skalicky and Vijil and $2,000,000 for Mr. Bonny. The Retention Grant vests 50% on September 30, 2012 and 50% on December 31, 2013. Pursuant to the Retention Agreements, the Retention Grant is generally subject to pro rata vesting upon a termination by Transatlantic without “Cause,” or due to death or “Disability,” or by the executive with “Good Reason,” in each case prior to December 31, 2013. Further, pursuant to the Retention Agreements, all of the outstanding, unvested equity awards held by each of the executives as of the effective date of the Retention Agreements is subject to full vesting upon a termination by Transatlantic without “Cause,” or by the executive with “Good Reason,” in each case prior to December 31, 2013. In consideration for entering into the Retention Agreements, each executive shall provide a limited waiver of the executive’s right to resign for “Good Reason” in connection with the merger as a result of the executive’s new employment position immediately following the merger.
 
The Retention Agreements include restrictive covenants similar to those included in Transatlantic’s Executive Severance Plan.
 
Treatment of Equity Awards
 
Transatlantic directors’ and executive officers’ outstanding stock options to acquire Transatlantic common stock will be converted pursuant to the merger agreement into options to acquire Allied World shares. Similarly, Transatlantic directors’ and executive officers’ outstanding stock-based awards will be converted into Allied World shares or other compensatory awards denominated in Allied World shares. The equity holdings of Transatlantic directors and executive officers will be treated in the same manner as the equity holdings of all other equity holders.
 
Allied World and Transatlantic are engaged in discussions relating to the adjustment of performance goals of all Allied World and Transatlantic stock-based awards that vest based on the achievement of performance criteria in order to appropriately reflect the merger with respect to performance periods that have not ended prior to the merger.

Golden Parachute Compensation
 
As described above, Transatlantic’s named executive officers are parties to Retention Agreements providing for the issuance of certain awards in connection with the merger. Other than as described above regarding such Retention Agreements, the merger is not considered a change in control under any plans or agreements of Transatlantic to which Transatlantic’s named executive officers are a party.
 
The following table sets forth the estimated amounts of “golden parachute” compensation (for purposes of Item 402(t) of Regulation S-K) that each named executive officer of Transatlantic could receive in connection with the merger. These amounts assume that the merger is completed on           , 2011 and, where applicable, that the named executive officer is entitled to the full amount for which he or she is eligible pursuant to the terms of the applicable Retention Agreement. Certain of the amounts payable may vary depending on the actual dates on which the merger is completed and the named executive officer terminates employment. As a result, the actual amounts, if any, to be received by a named executive officer may differ in material respects from the amounts set forth below.

(1) As noted above, these amounts assume that the named executive officer is entitled to the full amount for which he is eligible under the applicable Retention Agreement. These amounts would also be paid out, on a pro rata basis pursuant to the applicable Retention Agreement upon termination by Transatlantic without “Cause,” or due to death or “Disability” or by the executive with “Good Reason” prior to December 31, 2013, or upon death or disability of the executive prior to December 31, 2013. In consideration for entering into the Retention Agreements, each executive shall provide a limited waiver of the executive’s right to resign for “Good Reason” in connection with the merger.
 
Transatlantic Executive Severance Plan.  As discussed above, the merger is not considered a change in control under Transatlantic’s compensation plans or arrangements and a reduction in force is not anticipated in connection with the merger, including at the executive level. Whether or not the merger occurs, Transatlantic’s executives are entitled to certain payments in connection with certain terminations of employment. Under the Transatlantic Executive Severance Plan (“ESP”) severance protection is provided to senior executives who participate in the Transatlantic Partners or Senior Partners Plan. Upon a termination by Transatlantic without “Cause” (as defined in the ESP) or by the executive for “Good Reason” (as defined in the ESP), in addition to accrued wages and expense reimbursement, eligible employees will be entitled to receive the following each month during the Severance Period (30 months for the CEO and 24 months for the other named executive officers):
 
  •  severance in an amount equal to one-twelfth the sum of: (i) the participant’s annual base salary in the year of termination, (ii) any supplemental or quarterly cash bonus payable to such participant in respect of the year of termination, and (iii) the average of the participant’s annual cash bonus awards earned and paid with respect to the three most recently completed fiscal years;
 
  •  continued vesting of restricted stock units, earned but unvested performance restricted stock units and options as though there had been no termination of employment;


80


Table of Contents

 
  •  continued participation in Transatlantic’s health plan at active employee rates and continued service credit for eligibility and company contribution levels for purposes of the retiree health plan;
 
  •  continued vesting and accrual of additional non-qualified pension credits; and
 
  •  continued life insurance and retiree health plan coverage at active employee rates including continued service credit for eligibility and company contribution levels in such plans.
 
Prior to receiving any severance payments, eligible employees will be required to execute a general release of claims that also contains the following restrictions that, except as noted, apply at all times following termination:
 
  •  Each participant is generally prohibited from (i) engaging in, being employed by, rendering services to or acquiring financial interests in any business that is competitive with Transatlantic, (ii) interfering with Transatlantic’s business relationships with customers, suppliers, or consultants, or (iii) soliciting or hiring certain key employees of Transatlantic. These restrictions apply for the earlier of one year after termination or the length of the Severance Period.
 
  •  Each participant must not disclose Transatlantic’s confidential information.
 
Board of Directors and Management Following the Merger
 
Immediately following the effective time of the merger, assuming the receipt of the resignation letters of all current directors of Allied World and of shareholder approval for the election of directors as described herein, the board of directors of the combined company will consist of 11 members including (i) four independent Transatlantic directors, (ii) Richard S. Press (the current non-executive chairman of the Transatlantic board of directors), (iii) Michael C. Sapnar (the current Executive Vice President and Chief Operating Officer of Transatlantic), (iv) four independent Allied World directors and (v) Scott A. Carmilani (the current Chairman, President and Chief Executive Officer of Allied World). The 11 members of the board of directors of the combined company will be divided into three classes of directors, as follows:
 
  •  Class II (to hold office commencing upon the completion of the merger and ending upon TransAllied’s Annual Shareholder Meeting in 2012): two former independent Transatlantic directors and a former independent Allied World director;
 
  •  Class III (to hold office commencing upon the completion of the merger and ending upon TransAllied’s Annual Shareholder Meeting in 2013): two former independent Transatlantic directors and two former independent Allied World directors; and
 
  •  Class I (to hold office commencing upon the completion of the merger and ending upon TransAllied’s Annual Shareholder Meeting in 2014): Scott A. Carmilani, Richard S. Press, Michael C. Sapnar, and a former independent Allied World director.
 
Immediately following the effective time of the merger, Mr. Carmilani will serve as the President and Chief Executive Officer of the combined company. Mr. Press will be elected as non-executive chairman of the TransAllied board. Effective the first anniversary of the closing date of the merger, Mr. Press will cease to serve as non-executive chairman and shall remain on the TransAllied board as a director until the second anniversary of the closing date of the merger, at which time he has agreed to retire from the TransAllied board (subject to his earlier resignation or retirement). Mr. Sapnar will be appointed to serve as President and Chief Executive Officer of Global Reinsurance of the combined company.
 
In connection with the completion of the merger, the current directors of Allied World resign effective as of the effective time of the merger and the director nominees presented for election at the Allied World Shareholder Meeting, if elected by the shareholders, will serve on the board of directors of Allied World following the effective time of the merger. The foregoing director elections and officer appointments are conditioned upon completion of the merger. In the event that the merger is not completed, the foregoing director elections and officer appointments will not take effect.

Table of Contents

Pursuant to the terms of the merger agreement and conditioned upon completion of the merger, (i) in connection with the TransAllied Annual Shareholder Meeting in 2012, the TransAllied board shall propose to increase the size of the TransAllied board by one member and shall nominate for election at such meeting, a new director to fill the resulting vacancy, who shall become the non-executive chairman of the TransAllied board effective as of the first anniversary of the closing of the merger; (ii) such person nominated for election at such meeting shall (A) have been approved by the TransAllied board, (B) have been recommended by the nominating and corporate governance committee of the TransAllied board, (C) have substantial insurance industry expertise, and (D) not have been a member of the Transatlantic board of directors or the Allied World board of directors immediately prior to the date of the merger agreement; and (iii) TransAllied shall duly call, give notice of, convene and hold its Annual Shareholder Meeting in 2012 no later than June 30, 2012.
 
Upon completion of the merger, the TransAllied board will have six board committees: the Audit Committee, the Compensation Committee, the Enterprise Risk Committee, the Executive Committee, the Investment Committee and the Nominating & Corporate Governance Committee.
 
  •  For a period of one year from the closing date of the merger, the Executive Committee is to be comprised of Mr. Carmilani, one former independent Allied World director and two former independent Transatlantic directors, and to be chaired by Mr. Carmilani;
 
  •  For a period of one year from the closing date of the merger, each of the Investment Committee and Nominating & Corporate Governance Committee are to be comprised of two former independent Allied World directors and two former independent Transatlantic directors, and to be chaired by one of the former independent Allied World directors; and
 
  •  For a period of one year from the closing date of the merger, each of the Audit Committee, Compensation Committee and Enterprise Risk Committee are to be comprised of two former independent Allied World directors and two former independent Transatlantic directors, and chaired by one of the former independent Transatlantic directors.
 
Upon completion of the merger, the combined company’s corporate headquarters and related corporate functions will be located in Zug, Switzerland.
 
The appointments of Messrs. Carmilani, Press and Sapnar, the provisions regarding the selection of a replacement non-executive chairman, and the board committee composition, will be reflected in the TransAllied organizational regulations, which will only become effective at the completion of the merger, and, for a period of one year following the closing date, any resolution to revise, modify or delete such provisions will require a majority of at least eight of the votes cast.
 
Regulatory Clearances Required for the Merger
 
Under the HSR Act, Allied World and Transatlantic must file notifications with the FTC and the Antitrust Division and observe a mandatory pre-merger waiting period before completing the merger. The parties filed the required notifications with the FTC and Antitrust Division on July 1, 2011.
 
Premerger notifications must also be filed by Allied World and Transatlantic with the appropriate competition regulators in the United Kingdom, Germany, Italy and Turkey pursuant to their respective laws which are designed or intended to regulate actions having the purpose or effect of monopolization or restraint of trade or lessening of competition through merger or acquisition. They must also observe mandatory waiting periods and/or obtain the necessary approvals, clearances or consents, in certain of these jurisdictions, before completing the merger. The Italian notification was made on July 1, 2011. Notifications in the United Kingdom, Germany and Turkey will be made as promptly as practicable.
 
In addition to those filings required by the HSR Act and other antitrust laws, certain insurance regulatory filings will also be required to consummate the merger. State insurance laws in the United States generally require that, prior to the acquisition of any insurance company, the acquiring party must obtain approval from the insurance commissioner of the insurance company’s state of domicile, and the parties have and will make the required filings in accordance with such laws. In addition, applications or notifications have been or will


82


Table of Contents

be filed with various insurance regulatory authorities outside of the United States in connection with the changes in control that may be deemed to occur as a result of the transaction.
 
Allied World and Transatlantic cannot assure you that the Antitrust Division, FTC or other government agencies, including state attorneys general or private parties, will not initiate actions to challenge the merger before or after it is completed. Any such challenge to the merger could result in a court order enjoining the merger or in restrictions or conditions that would have a material adverse effect on the combined company if the merger is completed. Such restrictions and conditions could include requiring the divestiture or spin-off of assets or businesses. Under the terms of the merger agreement, each of Allied World and Transatlantic is required to commit to any divestitures or similar arrangements with respect to its assets or conduct of business arrangements if that divestiture or arrangement is a condition to obtain any clearance or approval from any governmental entity in order to complete the merger. No additional shareholder approval is expected to be required or sought for any decision by Allied World and Transatlantic after the Allied World Special Shareholder Meeting and the Transatlantic Special Shareholder Meeting to agree to any terms and conditions necessary to resolve any regulatory objections to the merger.
 
Exchange of Shares in the Merger
 
Prior to the effective time of the merger, Allied World and Transatlantic will appoint an exchange agent to handle the exchange of shares of Transatlantic common stock for Allied World shares. At the effective time of the merger, shares of Transatlantic common stock will be converted into the right to receive 0.88 Allied World shares, together with cash in lieu of fractional Allied World shares (the “merger consideration”) without the need for any action by the holders of Transatlantic common stock.
 
As soon as reasonably practicable after the effective time of the merger, Allied World will cause the exchange agent to mail each holder of Transatlantic certificates or book-entry shares a letter of transmittal specifying, among other things, that delivery will be effected, and risk of loss and title in respect of the certificates or book-entry shares will pass, only upon proper delivery of such certificates to the exchange agent, or in the case of book-entry shares, upon adherence to the procedures set forth in the letter of transmittal. The letter of transmittal will also include instructions explaining the procedure for surrendering Transatlantic stock certificates in exchange for the applicable merger consideration and any dividends or other distributions.
 
After the effective time of the merger, shares of Transatlantic common stock will no longer be outstanding, will be automatically canceled and will cease to exist and each certificate and book-entry share that previously represented shares of Transatlantic common stock will represent only the right to receive the merger consideration as described above. With respect to such Allied World shares deliverable upon the surrender of Transatlantic certificates and book-entry shares, until holders of such Transatlantic certificates and book-entry shares have surrendered such certificates and book-entry shares to the exchange agent for exchange, those holders will not receive dividends or distributions with respect to such Allied World shares with a record date after the effective time of the merger.
 
Transatlantic stockholders will not receive any fractional Allied World shares pursuant to the merger. Instead, each Transatlantic stockholder who otherwise would have been entitled to receive a fraction of an Allied World share will receive, in lieu thereof and, upon surrender of his or her shares of Transatlantic common stock, an amount in cash for such fraction calculated by multiplying the fractional share interest to which such holder would otherwise be entitled by the last reported sale price of the Allied World shares listed on the NYSE (as reported in The Wall Street Journal (Northeast edition) or if not reported there, in another authoritative source mutually selected by Allied World and Transatlantic) at the effective time of the merger, on the first trading day immediately following the date on which the effective time of the merger occurs.
 
Allied World shareholders need not take any action with respect to their stock certificates.

Treatment of Transatlantic Stock Options and Other Long-Term Incentive Awards
 
Prior to the effective time of the merger, the board of directors of Allied World (or, if appropriate, the committee thereof administering the Allied World stock plans) will adopt resolutions or take other actions as may be required to effect the below actions with respect to the Transatlantic stock options and stock-based awards.
 
Stock Options.  Upon completion of the merger, each outstanding option to purchase shares of Transatlantic common stock will be converted pursuant to the merger agreement into a stock option to purchase shares of Allied World shares on the same terms and conditions as were in effect immediately prior to the completion of the merger based on the exchange ratio.
 
Stock-Based Awards.  Upon completion of the merger, each outstanding stock-based award of Transatlantic will be converted into Allied World shares or other compensatory awards denominated in Allied World shares subject to a risk of forfeiture to, or the right to repurchase by, Allied World, with the same terms and conditions as were applicable under such Transatlantic stock-based awards, and each holder of Transatlantic stock-based awards shall be entitled to receive a number of converted Transatlantic stock-based awards equal to the product of the number of Transatlantic stock-based awards held by such holder and the exchange ratio.
 
Allied World and Transatlantic are engaged in discussions relating to the adjustment of performance goals of all Allied World and Transatlantic stock-based awards that vest based on the achievement of performance criteria in order to appropriately reflect the merger with respect to performance periods that have not ended prior to the merger.
 
Dividend Policy
 
Under Swiss law, dividends may be paid out only if Allied World has sufficient distributable profits from previous fiscal years or if Allied World has freely distributable reserves, each as will be presented on Allied World’s audited statutory financial statements prepared in accordance with Swiss law. Payments out of the share and participation capital (in other words, the aggregate par value of Allied World’s share and participation capital) in the form of dividends are not allowed; however, payments out of share and participation capital may be made by way of a capital reduction to achieve a similar result as the payment of dividends. The affirmative vote of shareholders holding a majority of the votes cast at a shareholder meeting where two or more persons are present at the meeting representing in person or by proxy more than 50% of Allied World’s total outstanding registered shares throughout the meeting, must approve reserve reclassifications and distributions of dividends. Allied World’s board of directors may propose to shareholders that a dividend be paid but cannot itself authorize the dividend. In addition, Allied World’s shareholders may propose dividends without any dividend proposal by the board of directors. Under Swiss law, upon satisfaction of all legal requirements (including shareholder approval of a par value reduction), Allied World is required to submit an application to the Swiss Commercial Register to register each applicable par value reduction. Without effective registration of the applicable par value reduction with the Swiss Commercial Register, Allied World will not be able to proceed with the payment of any installment of any dividend. Allied World cannot assure you that the Swiss Commercial Register will approve the registration of any applicable par value reduction.
 
Under Swiss law, if the Allied World general capital reserves amount to less than 20% of the share and participation capital recorded in the Swiss Commercial Register (i.e., 20% of the aggregate par value of Allied World’s capital), then at least 5% of Allied World’s annual profit must be retained as general reserves. Swiss law permits Allied World to accrue additional general reserves. In addition, Allied World is required to create a special reserve on its audited statutory financial statements in the amount of the purchase price of voting shares and Allied World non-voting shares Allied World or any of its subsidiaries repurchases, which amount may not be used for dividends.
 
Swiss companies generally must maintain separate audited statutory financial statements for the purpose of, among other things, determining the amounts available for the return of capital to shareholders, including by way of a distribution of dividends. Amounts available for the return of capital as indicated on Allied


84


Table of Contents

World’s audited statutory financial statements may be materially different from amounts reflected in Allied World’s consolidated GAAP financial statements. Allied World’s auditor must confirm that a dividend proposal made to shareholders complies with Swiss law and the Allied World Articles.
 
Allied World is required under Swiss law to declare any dividends and other capital distributions in Swiss francs. Allied World makes dividend payments to holders of its shares in U.S. dollars. Continental Stock Transfer & Trust Company, Allied World’s transfer agent, will be responsible for paying the U.S. dollars to registered holders of Allied World shares and Allied World non-voting shares, less amounts subject to withholding for taxes. As a result, shareholders may be exposed to fluctuations in the U.S. dollar — Swiss franc exchange rate between the date used for purposes of calculating the Swiss franc amount of any proposed dividend or par value reduction and the relevant payment date.
 
Listing of Allied World Shares
 
It is a condition to the completion of the merger that the shares of Allied World shares to be issued to Transatlantic stockholders pursuant to the merger be authorized for listing on the NYSE at the effective time of the merger.
 
De-Listing and Deregistration of Transatlantic Common Stock
 
Upon completion of the merger, shares of Transatlantic common stock currently listed on the NYSE will cease to be listed on the NYSE and will subsequently be deregistered under the Exchange Act.
 
No Appraisal Rights
 
Holders of Transatlantic common stock who dissent to the merger will not have rights to an appraisal of the fair value of their shares. Under the General Corporation Law of the State of Delaware (the “DGCL”), appraisal rights are not available for the shares of any class or series if the shares of the class or series are listed on a national securities exchange or held of record by more than 2,000 holders on the record date, unless the stockholders receive in exchange for their shares anything other than shares of stock of the surviving or resulting corporation or of any other corporation that is publicly listed or held by more than 2,000 holders of record, cash in lieu of fractional shares or fractional depositary receipts or any combination of the foregoing. Transatlantic’s common stock is listed on the NYSE, and Transatlantic stockholders will receive Allied World shares, which are listed on the NYSE, and cash in lieu of fractional shares. Holders of Allied World shares have no appraisal rights under Swiss law because the merger does not qualify as a statutory merger pursuant to the provisions of the Federal Act on Mergers, Demergers, Transformations and the Transfer of Assets (the “Merger Act”).
 
Litigation Related to the Merger
 
In connection with the merger, five putative stockholder class action lawsuits have been filed against Transatlantic, Allied World, and the members of the Transatlantic board of directors challenging the merger: Ivers v. Transatlantic Holdings, Inc., et al. (filed June 17, 2011 in the Court of Chancery of the State of Delaware), Clark v. Transatlantic Holdings, Inc., et al. (filed June 17, 2011 in the Supreme Court of the State of New York, County of New York and amended on June 22, 2011), Sutton v. Transatlantic Holdings, Inc., et al. (filed June 17, 2011 in the Supreme Court of the State of New York, County of New York), Jaroslawicz v. Transatlantic Holdings, Inc., et al. (filed June 21, 2011 in the Supreme Court of the State of New York, County of New York) and Kramer v. Transatlantic Holdings, Inc., et al. (filed June 30, 2011 in the Court of Chancery of the State of Delaware) (collectively, the “Lawsuits”). Each of the Lawsuits has been filed against Transatlantic, the members of the Transatlantic board of directors, and Allied World. In addition, other than the Jaroslawicz action, each of the Lawsuits names as a defendant GO Sub, LLC. Further, the Sutton action also names Thomas R. Tizzio, a former director of Transatlantic, as a defendant. Plaintiffs in each Lawsuit assert that the members of the Transatlantic board of directors breached their fiduciary duties and that Allied World and/or its subsidiaries aided and abetted the alleged breaches of fiduciary duties. In addition, in the


85


Table of Contents

Clark action, plaintiffs allege that Transatlantic aided and abetted its directors’ alleged breaches of fiduciary duty. The Lawsuits seek, among other relief, to enjoin the merger.
 
On June 29-30, 2011, the defendants moved to dismiss or stay the three actions pending in New York — the Clark, Sutton, and Jaroslawicz actions — on the grounds that the Ivers action is a parallel proceeding pending in the Delaware Court of Chancery seeking the same relief as the three New York actions.
 
Transatlantic, Allied World and their respective directors believe these lawsuits are without merit and intend to defend them vigorously.
 
The Combined Company’s Share Repurchase Program Post-Merger
 
In May 2010, the Allied World board of directors authorized Allied World to repurchase up to $500 million of its shares through a share repurchase program. Prior to Allied World’s redomestication to Switzerland, Allied World Assurance Company Holdings, Ltd, as Allied World’s then sole shareholder, approved the repurchase of Allied World shares in an amount not to exceed $160 million, which represented a portion of the remaining capacity available under the original May 2010 share repurchase authorization. At Allied World’s Annual Shareholder Meeting in 2011, Allied World shareholders approved the $122.5 million of remaining capacity available under such authorization. As of June 30, 2011, Allied World had an aggregate of $200.8 million of capacity available under its share repurchase program.
 
Following the completion of the merger, the combined company intends to reevaluate its share repurchase program as part of its year-end review and in preparation for its Annual Shareholder Meeting in 2012.

THE MERGER AGREEMENT
 
The following section summarizes material provisions of the merger agreement, which is included in this joint proxy statement/prospectus as Annex A and is incorporated herein by reference in its entirety. The rights and obligations of Allied World and Transatlantic are governed by the express terms and conditions of the merger agreement and not by this summary or any other information contained in this joint proxy statement/prospectus. Allied World shareholders and Transatlantic stockholders are urged to read the merger agreement carefully and in its entirety as well as this joint proxy statement/prospectus before making any decisions regarding the merger, including with respect to the approval of the share capital increase proposals, the NYSE share issuance proposal, the name change proposal, the election of directors proposal and the adoption of the merger agreement proposal, as applicable.
 
The merger agreement is included in this joint proxy statement/prospectus to provide you with information regarding its terms and is not intended to provide any factual information about Allied World or Transatlantic. The merger agreement contains representations and warranties by each of the parties to the merger agreement. These representations and warranties have been made solely for the benefit of the other parties to the merger agreement and:
 
  •  may not be intended as statements of fact, but rather as a way of allocating the risk between the parties in the event the statements therein prove to be inaccurate;
 
  •  have been qualified by certain disclosures that were made between the parties in connection with the negotiation of the merger agreement, which disclosures are not reflected in the merger agreement itself; and
 
  •  may apply standards of materiality in a way that is different from what may be viewed as material by you or other investors.
 
Accordingly, the representations and warranties and other provisions of the merger agreement should not be read alone, but instead should be read together with the information provided elsewhere in this joint proxy statement/prospectus and in the documents incorporated by reference into this joint proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 159.
 
This summary is qualified in its entirety by reference to the merger agreement.
 
Terms of the Merger; Merger Consideration
 
The merger agreement provides that, on the terms and subject to the conditions set forth in the merger agreement and in accordance with the DGCL, at the effective time of the merger, Merger Sub, a Delaware limited liability company and wholly-owned subsidiary of Allied World, will merge with and into Transatlantic. Transatlantic will be the surviving corporation in the merger and will become a wholly-owned subsidiary of Allied World. At the effective time of the merger, each outstanding share of Transatlantic common stock (other than shares owned by Transatlantic, Allied World or Merger Sub, which will be canceled and cease to exist) will be converted into the right to receive 0.88 (the ratio of such number to one, referred to herein as the exchange ratio) Allied World shares.
 
Allied World will not issue fractional Allied World shares pursuant to the merger agreement. Instead, each Transatlantic stockholder that otherwise would have been entitled to receive a fraction of an Allied World share will receive, in lieu thereof and, upon surrender of his or her shares of Transatlantic common stock, an amount in cash for such fraction calculated by multiplying the fractional share interest to which such holder would otherwise be entitled by the last reported sale price of the Allied World shares listed on the NYSE (as reported in The Wall Street Journal (Northeast edition) or if not reported there, in another authoritative source mutually selected by Allied World and Transatlantic) at the effective time of the merger, on the first trading day immediately following the date on which the merger is effective.
 
The merger consideration will be adjusted appropriately and proportionately to fully reflect the effect of any stock dividend, subdivision, reorganization, reclassification, recapitalization, stock split, reverse stock split,


87


Table of Contents

combination, exchange of shares or other similar event with respect to Allied World shares or Transatlantic common stock prior to the effective time of the merger.
 
Completion of the Merger
 
Unless the parties agree otherwise, the closing of the merger will take place no later than the second business day after all conditions to the completion of the merger have been satisfied or waived. The merger will be effective when the parties duly file (i) the certificate of merger with the Secretary of State of the State of Delaware and (ii) the TransAllied Articles with the appropriate Swiss governmental entity. The TransAllied Articles will be filed immediately prior to the filing of the certificate of merger, at which time the merger will become effective.
 
Allied World and Transatlantic currently expect the closing of the merger to occur in the fourth quarter of 2011. However, as the merger is subject to various regulatory clearances and the satisfaction or waiver of other conditions described in the merger agreement, it is possible that factors outside the control of Allied World and Transatlantic could result in the merger being completed at an earlier time, a later time or not at all.
 
Exchange of Shares in the Merger
 
Prior to the effective time of the merger, Allied World and Transatlantic will appoint an exchange agent to handle the exchange of shares of Transatlantic common stock for Allied World shares. At the effective time of the merger, shares of Transatlantic common stock will be converted into the right to receive 0.88 Allied World shares, together with cash in lieu of fractional Allied World shares, without the need for any action by the holders of Transatlantic common stock.
 
As soon as reasonably practicable after the effective time of the merger, Allied World will cause the exchange agent to mail each holder of certificates or book-entry shares a letter of transmittal specifying, among other things, that delivery will be effected, and risk of loss and title in respect of the certificates or book-entry shares will pass, only upon proper delivery of such certificates to the exchange agent, or in the case of book-entry shares, upon adherence to the procedures set forth in the letter of transmittal. The letter will also include instructions explaining the procedure for surrendering Transatlantic certificates and book-entry shares in exchange for the applicable merger consideration and any dividends or other distributions. Upon proper surrender of a certificate or book-entry share to the exchange agent, together with the letter of transmittal, the holder of such certificate or book-entry share will be entitled to receive in exchange therefor Allied World shares representing that number of whole Allied World shares that such holder has the right to receive and a check representing cash in lieu of fractional shares.
 
After the effective time of the merger, shares of Transatlantic common stock will no longer be outstanding, will be automatically canceled and will cease to exist, and each certificate and book-entry share that previously represented shares of Transatlantic common stock will represent only the right to receive the merger consideration as described above, any cash in lieu of fractional Allied World shares and any dividends or other distributions to which the holders of the certificates become entitled upon surrender of such certificates and book-entry shares. With respect to such Allied World shares deliverable upon the surrender of Transatlantic stock certificates, until holders of such Transatlantic certificates and book-entry shares have surrendered such certificates and book-entry shares to the exchange agent for exchange, those holders will not receive dividends or distributions with respect to such Allied World shares with a record date after the effective time of the merger.

Many of the representations and warranties in the merger agreement are qualified by a “materiality” or “material adverse effect” standard (that is, they will not be deemed to be untrue or incorrect unless their failure to be true or correct, individually or in the aggregate, would, as the case may be, be material or have a material adverse effect). For purposes of the merger agreement, a “material adverse effect” means, with respect to a party, any change, state of facts, circumstance, event or effect that, individually or in the aggregate, is materially adverse to either (i) the ability of such party to perform its obligations under the merger agreement, or (ii) the financial condition, properties, assets, liabilities, obligations, business or results of operations of such party and its subsidiaries, taken as a whole, except that clause (ii) of the definition of “material adverse effect” excludes any effect that results from or arises in connection with:
 
  •  entering into or complying with the merger agreement or the public announcement or pendency of the merger or any of the other transactions contemplated by the merger agreement, including the impact of so entering into the merger agreement on the relationships of such party or any of its subsidiaries with employees, customers, brokers, agents, financing sources, suppliers or partners, and regulators;
 
  •  changes in law following the date of the merger agreement;
 
  •  changes in GAAP or SAP following the date of the merger agreement (or local equivalents in the applicable jurisdiction) prescribed by the applicable insurance regulatory authority, including accounting and financial reporting pronouncements by the SEC, the National Association of Insurance Commissioners and the Financial Accounting Standards Board;
 
  •  any change or announcement of a potential change in such party’s or such party’s subsidiaries’ credit or claims paying rating or A.M. Best Company rating or the ratings of such party or such party’s subsidiaries’ businesses or securities (however, the facts or occurrences giving rise to such a change may be deemed to constitute or be taken into account in determining whether there has been or will be a material adverse effect);
 
  •  a suspension of trading or a change in the trading prices of such party’s common stock (however, the facts or occurrences giving rise to such failure may be deemed to constitute or be taken into account in determining whether there has been or will be a material adverse effect);
 
  •  the failure to meet any revenue, earnings or other projections, forecasts or predictions for any period ending after the date of the merger agreement (however, the facts or occurrences giving rise to such failure may be deemed to constitute or be taken into account in determining whether there has been or will be a material adverse effect);
 
  •  any action or failure to act expressly required to be taken by a party pursuant to the terms of the merger agreement;
 
  •  to the extent the following changes, state of facts, circumstances, events or effects do not have a materially disproportionate effect on such party and its subsidiaries, taken as a whole, relative to other companies of similar size operating in the property and casualty insurance and/or reinsurance industry, as applicable:
 
  •  changes in economic, market, business regulatory or political conditions generally in the United States or any other jurisdiction in which such party or its subsidiaries operate or in the United States or global financial markets;
 
  •  changes, circumstances or events generally affecting the property and casualty insurance and/or reinsurance industry in the geographic areas in which such party and its subsidiaries operate;

No Solicitation of Alternative Proposals
 
Each of Allied World and Transatlantic has agreed that, from the time of the execution of the merger agreement until the earlier of the termination of the merger agreement or the completion of the merger, it will not and it will cause its subsidiaries and its and their directors and officers, and will use its reasonable best efforts to cause its controlled affiliates, employees, agents, consultants and representatives, not to, directly or indirectly, (i) solicit, initiate or knowingly encourage or facilitate (including by way of furnishing information) or take any other action designed to facilitate any inquiries or proposals regarding, or that would reasonably be expected to lead to, any merger, share exchange, amalgamation, consolidation, sale of assets, sale of shares of capital stock (including by way of a tender offer or exchange offer) or similar transactions that, if consummated, would constitute a competing proposal (as defined below), (ii) solicit, initiate, knowingly encourage or participate in any discussions or negotiations regarding, or furnish to any person any information in connection with, or otherwise cooperate in any way with, or knowingly facilitate in any way any effort by any person in connection with any acquisition proposal (as defined below) or (iii) enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other agreement regarding, or that is intended to result in, or would be reasonably expected to lead to, an acquisition proposal.
 
An “acquisition proposal” with respect to a party means any inquiry or proposal regarding, or that would reasonably be expected to lead to, any merger, share exchange, amalgamation, consolidation, sale of assets, sale of shares of capital stock (including by way of a tender offer or exchange offer) or similar transaction involving such party or any of its subsidiaries that, if consummated, would constitute a competing transaction. A “competing transaction” with respect to a party means (i) any transaction, including a tender offer, exchange offer or share exchange, pursuant to which any third-party or group, directly or indirectly, acquires or would acquire beneficial ownership of 10% or more of the outstanding shares of such party’s common stock or outstanding voting power (or options, rights or warrants to purchase, or securities convertible into or exchangeable for, such common stock or ordinary shares or other securities representing such voting power), (ii) a merger, amalgamation, consolidation or business combination pursuant to which any third-party or group would beneficially own 10% or more of such party’s outstanding common stock or outstanding voting power or (iii) a recapitalization or any other transaction pursuant to which a third-party or group beneficially owns or would beneficially own 10% or more of such party’s outstanding common stock or outstanding voting power or (iv) any transaction pursuant to which any third-party or group, directly or indirectly, acquires or would acquire control of assets of such party or its subsidiaries representing 10% or more of consolidated revenues, net income, EBITDA for the last 12 months or the fair market value of all of such party’s assets and its subsidiaries, taken as a whole.
 
Notwithstanding the restrictions described above, prior to obtaining the relevant stockholder approvals, the board of directors of each of Allied World and Transatlantic is permitted to furnish information with respect to Allied World or Transatlantic, as applicable, and enter into discussions with, and only with, a person who has made an unsolicited bona fide written acquisition proposal if the board of directors of such party (i) determines in good faith (after consultation with its outside legal counsel and financial advisors) that such acquisition proposal constitutes or is reasonably likely to lead to a superior proposal (as defined below) and the failure to enter into discussions regarding such proposal would result in a breach of such board’s fiduciary duties, (ii) provides at least three business days’ notice to the other party of its intent to furnish information to, or enter into discussions with, such person and (iii) obtains from such person an executed confidentiality

agreement. A “superior proposal” with respect to a party means a bona fide written acquisition proposal made by a third-party or group (and not obtained in breach of the merger agreement) for a merger, amalgamation, consolidation, business combination or other similar transaction involving such party pursuant to which the Allied World shareholders or Transatlantic stockholders, as applicable, immediately preceding the transaction would hold less than 50% of the outstanding common stock or voting power of such party or the surviving or parent entity following the consummation of such transaction that the board of directors of such party (after consultation with its outside legal counsel and financial advisors) determines in good faith to be more favorable to such party’s stockholders than the merger. In making such determination, the board of directors of such party will take into account all relevant factors, including value and other financial considerations, legal and regulatory considerations, and any conditions to, and expected timing and risks of, completion, as well as any changes to the terms of the merger proposed by the other party in response to such superior proposal.
 
The merger agreement requires that the parties notify each other within 24 hours of, among other things, the receipt of any acquisition proposal or inquiry or request for non-public information that is reasonably likely to lead to an acquisition proposal. Any such notification will include the identity of the person making the inquiry and the material terms and conditions of any acquisition proposal. In addition, the merger agreement requires the parties to continue to update each other of material changes to any acquisition proposal and provide to each other, within 24 hours of receipt, all correspondence and other written material received from any third party in connection with an acquisition proposal. The merger agreement also requires both Allied World and Transatlantic to cease, and cause to be terminated, all discussions or negotiations with any person conducted prior to the execution of the merger agreement with respect to any acquisition proposal and request the prompt return or destruction of all confidential information previously furnished in connection therewith.
 
Changes in Board Recommendations
 
The board of directors of each of Allied World and Transatlantic has agreed that it will not (A) (i) withdraw (or modify in a manner adverse to the other party) the approval, recommendation or declaration of advisability by such board of the merger agreement or the transactions contemplated by the merger agreement, (ii) adopt, approve, recommend, endorse or otherwise declare advisable the adoption of any acquisition proposal or (iii) resolve, agree or publicly propose to take any such actions (any such action set forth in clause (A), an “adverse recommendation change”) or (B) cause or permit such party to enter into, or resolve, agree or propose publicly to do so with respect to, any agreement regarding an acquisition proposal.
 
Notwithstanding the restrictions described above, at any time prior to obtaining the relevant stockholder approvals, the board of directors of Allied World or Transatlantic, as applicable, may make an adverse recommendation change if such board determines in good faith that the failure to do so would result in a breach of the board’s fiduciary duties under applicable law, taking into account all adjustments to the terms of the merger agreement that may be offered by the other party. Prior to taking any such action, such board of directors must (x) inform the other party in writing of its decision at least three business days prior to changing its recommendation and specify the reasons therefor, including the terms and conditions of, and the identity of any person making, any acquisition proposal and (y) in the event the other party adjusts the terms of the merger agreement, the board of directors must determine that the adverse recommendation change is still required in the exercise of its fiduciary duties after giving effect to all relevant factors, including the payment of any applicable termination fees.
 
If the board of directors of Allied World or Transatlantic withdraws or modifies its recommendation, such board of directors will nonetheless continue to be obligated to hold its stockholders meeting and submit the proposals described in this joint proxy statement/prospectus to its stockholders for their vote, as applicable.
 
Efforts to Obtain Required Stockholder Votes
 
Allied World has agreed to hold the Allied World Special Shareholder Meeting and to use its reasonable best efforts to obtain shareholder approval for the share capital increase proposals, the NYSE share issuance proposal, the name change proposal and the election of directors proposal. The merger agreement requires


93


Table of Contents

Allied World to submit these proposals to a shareholder vote even if its board of directors no longer recommends the proposals. The Allied World board of directors has approved the issuance of Allied World shares to Transatlantic stockholders pursuant to the merger and the amendment to the Allied World Articles and has adopted resolutions directing that the proposals herein be submitted to Allied World shareholders for their consideration.
 
Transatlantic has also agreed to hold the Transatlantic Special Shareholder Meeting and to use its reasonable best efforts to obtain stockholder approval for the adoption of the merger agreement proposal. The merger agreement requires Transatlantic to submit the merger agreement to a stockholder vote even if its board of directors no longer recommends the adoption of the merger agreement proposal. The board of directors of Transatlantic has approved the merger agreement and declared the merger agreement and the transactions contemplated thereby, including the merger, advisable and in the best interests of Transatlantic and its stockholders and adopted resolutions directing that the merger agreement be submitted to the Transatlantic stockholders for their consideration.
 
Efforts to Complete the Merger
 
Allied World and Transatlantic have each agreed to:
 
  •  take, or cause to be taken, all actions, and do, or cause to be done, and assist and cooperate with the other parties in doing, all things necessary to consummate and make effective, as soon as reasonably possible, the merger and the other transactions contemplated by the merger agreement; and
 
  •  take, or cause to be taken, all actions, to file, or cause to be filed, all documents and to do, or cause to be done, all things necessary, proper or advisable to consummate the transactions contemplated by the merger agreement, including preparing and filing as promptly as practicable all documentation to effect all necessary filings, consents, waivers, approvals, authorizations, permits or orders from all third parties and governmental entities, so as to enable the completion of the merger as soon as reasonably practicable.
 
Additionally, Allied World and Transatlantic have each agreed to:
 
  •  make and cause to be made all necessary registrations, filings and notices relating to the merger with governmental entities under certain applicable antitrust laws;
 
  •  respond, as promptly as practicable under the circumstances, to any inquiries received from any governmental entity for additional information or documentation in connection with antitrust, competition, trade regulation or similar matters;
 
  •  use reasonable best efforts to achieve substantial compliance as promptly as practicable with any second request received by the Antitrust Division or FTC;
 
  •  certify substantial compliance with any second request as promptly as practicable after the date of such second request (but no later than December 15, 2011) and take all actions necessary to assert, defend and support such certification; and
 
  •  not extend any waiting period under any antitrust law or enter into any agreement with a governmental entity or other authority to delay, or otherwise not consummate as soon as practicable, any of the transactions contemplated by the merger agreement.
 
In furtherance of these obligations, if necessary and sufficient to consummate the merger, Allied World and Transatlantic have agreed to jointly propose, negotiate, commit to and effect the holding separate, sale divestiture or other disposition of, or prohibition or limitation on, (i) the ownership or operation by either party of any of their respective subsidiaries, (ii) the ability of Allied World to acquire or hold, or exercise full right of ownership of, any shares of capital stock of any of its subsidiaries, Transatlantic, or Transatlantic’s subsidiaries, or (iii) Allied World or any of its subsidiaries effectively controlling the business and operations of Allied World and its subsidiaries or Transatlantic and its subsidiaries.

Cantonal Tax Ruling
 
On June 14, 2011, Allied World obtained a tax ruling from the Cantonal Tax Administration of the Canton of Zug, providing that the merger does not result in income taxes for Allied World (and, in particular, the recording of the newly issued Allied World shares in the merger is not subject to income taxes).

Prior to the merger becoming effective, Allied World will use its reasonable best efforts to deliver to Transatlantic, agreements executed by certain persons, provided that (i) any change in status or reduction of duties directly resulting from the merger will not constitute “good reason” for purposes of determining such person’s entitlement to severance benefits or the acceleration of any vesting or other rights and (ii) the merger, standing alone, will not result in the acceleration of any vesting or other rights for such person.
 
Treatment of Transatlantic Stock Options and Other Stock-Based Awards and Programs
 
Prior to the effective time of the merger, the board of directors of Allied World (or, if appropriate, the committee thereof administering the Allied World stock plans) will adopt resolutions or take other actions as may be required to effect the below actions with respect to the Transatlantic stock options and stock-based awards.
 
Stock Options.  Upon completion of the merger, each outstanding option to purchase shares of Transatlantic common stock will be converted pursuant to the merger agreement into a stock option to acquire Allied World shares on the same terms and conditions as were in effect immediately prior to the completion of the merger. The number of Allied World shares underlying each converted Transatlantic stock option will be determined by multiplying the number of shares of Transatlantic common stock subject to such stock option immediately prior to the completion of the merger by the exchange ratio, and rounding down to the nearest whole share. The exercise price per share of each converted Transatlantic stock option will be determined by dividing the per share exercise price of such stock option by the exchange ratio, and rounding up to the nearest whole cent.

Any Transatlantic stock-based awards that vest based on the achievement of performance criteria will be adjusted (subject to the approval of Allied World) to appropriately reflect the merger with respect to performance periods that have not ended prior to the effective time of the merger. Pursuant to the merger agreement, Allied World and Transatlantic are engaged in discussions relating to the adjustment of performance goals of all Allied World and Transatlantic stock-based awards that vest based on the achievement of performance criteria in order to appropriately reflect the merger with respect to performance periods that have not ended prior to the merger.

CAPITAL INCREASES
 
The Allied World board of directors proposes approval of an increase of the ordinary share capital where the contributions for the new registered shares are paid by converting existing reserves (Kapitaleinlagen) into share capital and of amendments to Articles 5(a) (Conditional Share Capital for Employee Benefit Plans) and 6(a) (Authorized Share Capital for General Purposes) of the Articles of Association allowing for the grant to employees, consultants, directors or other person providing services to the Company or a subsidiary of the Company and to authorize the board of directors to increase Allied World’s share capital to issue common shares for general matters.
 
The proposal to increase the ordinary share capital, also referred to herein as the article 3 share capital increase proposal, would provide for a new amount of ordinary share capital of CHF          , divided into           registered shares with a par value of CHF           per share. The increase of the ordinary share capital will occur by converting existing reserves (Kapitaleinalgen) and the new shares will be fully paid-in. Upon resolution of the general meeting of shareholders in accordance with the Allied World Articles, registered shares may be converted into bearer shares and bearer shares may be converted into registered shares, at any time. In connection therewith, the proposal would limit or withdraw the shareholders’ pre-emptive rights.
 
The amendment to article 5(a) of the Allied World Articles, also referred to herein as the article 5 share capital increase proposal, would provide for a conditional share capital increase in an amount not exceeding CHF           through the issue from time to time of a maximum of          registered shares, payable in full, each with a par value of CHF          , in connection with the exercise of option rights granted to any employee of Allied World or any subsidiary thereof, and any consultant, director or other person providing services to Allied World or any subsidiary, thereof. These shares will be issued on account of the Transatlantic stock options that will be converted to Allied World options pursuant to the merger agreement. With regard to the issuance of the shares under article 5, shareholders’ pre-emptive rights will be excluded. The new registered shares may be issued at a price below the current market price. The Allied World board of directors will specify the precise conditions of issue, including the issuance price of the shares.
 
The amendment to article 6(a) of the Allied World Articles, also referred to herein as the article 6 share capital increase proposal, would allow the board of directors to increase the share capital from time to time and at any time until [two years from Special Shareholder Meeting date] by an amount not exceeding CHF           through the issue of up to           fully paid up registered shares with a par value of CHF 15.00 each (as may be adjusted in connection with the payment of dividends by virtue of a par value reduction as approved by Allied World’s shareholders at Allied World’s Annual Shareholder Meeting in 2011). Allied World proposes to increase the number of shares authorized to permit more ability to effect somewhat larger, or multiple, transactions more efficiently, and under timeframes that might not be possible were additional shareholder approvals required to be obtained. The article 6 share capital increase will also provide for share increase under Transatlantic stock-based awards (other than Transatlantic stock options) that are converted to Allied World stock-based awards pursuant to the merger agreement. The Allied World board of directors is authorized to exclude the preemptive rights of shareholders and to allocate them to third parties in the event of the use of shares.
 
The authorized share capital approved pursuant to the article 6 share capital increase, or which has otherwise been approved by shareholders, will be available for issuance at such times and for such purposes as the Allied World board of directors may deem advisable without further action by Allied World’s shareholders, except as may be required by applicable laws or regulations. For example, the additional authorized share capital pursuant to the article 6 share capital increase will be available for issuance by the Allied World board of directors in connection with mergers, acquisitions of enterprises or participants, financing and/or refinancing of such mergers and acquisitions and of other investment projects, improving the regulatory capital position of Allied World or its subsidiaries, broadening the shareholder constituency, the participation of employees or an exchange of participation certificates, as well as a buy back of participation certificates in exchange of registered shares. Allied World believes this is an important step to help ensure that the Allied World board of directors can adapt and react to a changing economic climate, business challenges including increased catastrophes and opportunities in capital and other relevant markets. Allied World does not intend to issue any

stock except on terms or for reasons which the Allied World board of directors deems to be in the best interests of Allied World.
 
Approval of the share capital increase proposals, as discussed above, are a condition to the completion of the merger and will be effected only immediately prior to the closing of the merger. In addition, the share capital increases are necessary to effect the merger. If such proposals are not approved, the merger will not be completed even if the NYSE share issuance proposal approving the issuance of Allied World shares in the merger is approved by Allied World shareholders and the proposal to approve the merger agreement is approved by Transatlantic stockholders. In addition, if the issuance of Allied World shares in the merger is not approved by Allied World shareholders, or the proposal to approve the merger agreement is not approved by Transatlantic stockholders, but any of the share capital increase proposals are approved, such capital increases will not be effected.
 
Approval of each of the share capital increase proposal requires the affirmative vote of at least 662/3% of the votes represented at the Allied World Special Shareholder Meeting and a majority of the nominal value of the Allied World shares, as represented at the Allied World Special Shareholder Meeting, where holders of at least 50% of the total outstanding Allied World shares are represented and voting and who are entitled to vote on such proposal. Abstentions and broker non-votes, which are described below, will not be considered votes cast and will have no effect on these proposals, assuming a quorum is present.
 
The Allied World board of directors unanimously recommends a vote “FOR” the ordinary share capital increase, including the limitation of the pre-emptive rights of the Allied World shareholders and the proposed amendments to articles 5(a) and 6(a) of the Allied World Articles, as described above.

NYSE SHARE ISSUANCE
 
The Allied World board of directors proposes the Allied World shareholders approve the issuance of the Allied World shares to Transatlantic stockholders pursuant to the merger and as contemplated by the merger agreement as required by NYSE rules, also referred to herein as the NYSE share issuance proposal. The merger agreement provides that as a condition to the closing of the merger that the Allied World shares to be issued to Transatlantic stockholders are authorized for listing on the NYSE, subject to official notice of issuance. NYSE listing policies require prior stockholder approval of issuances of common stock which would constitute more than 20% of the outstanding shares of common stock on a post transaction basis. Former Transatlantic stockholders are expected to hold approximately 58% of the outstanding Allied World shares, on a fully diluted basis, after giving effect to the merger. In order to issue the Allied World shares pursuant to the merger, the share capital increase proposals will each need to be approved at the Allied World Special Shareholder Meeting. In addition, in the event that the Allied World shareholders approve the NYSE share issuance proposal, but any of the election of directors proposal or the name change proposal are not approved by Allied World shareholders (and are not otherwise waived by each of Allied World and Transatlantic), or the proposal to approve the merger agreement is not approved by Transatlantic stockholders, the shares will not be issued.
 
The approval of the NYSE share issuance proposal requires the affirmative vote of the holders of a majority of shares entitled to vote on the proposal and present in person or represented by proxy at the Allied World Special Shareholder Meeting, provided that the total votes cast on this proposal represent over 50% of the outstanding Allied World shares entitled to vote on this proposal. Votes “for,” votes “against” and abstentions count as votes cast, while broker non-votes do not count as votes cast for this purpose. All outstanding Allied World shares, including broker non-votes, count as shares entitled to vote. Thus, the total sum of votes “for,” plus votes “against,” plus abstentions, which we refer to as the “NYSE votes cast,” must be greater than 50% of the total outstanding Allied World shares. The number of votes “for” the proposal must be greater than 50% of the NYSE votes cast.
 
The Allied World board of directors unanimously recommends a vote “FOR” the proposal to issue the Allied World shares to Transatlantic stockholders pursuant to the merger and as contemplated by the merger agreement as required by NYSE rules.

AMENDED AND RESTATED ARTICLES OF ASSOCIATION OF ALLIED WORLD
 
The Allied World board of directors proposes to the Allied World shareholders, subject to completion of the merger, to amend the Allied World Articles to change Allied World’s name to “TransAllied Group Holdings, AG”. The form of the amended Articles of Association, which is also referred to as the TransAllied Articles herein, is included in this joint proxy statement/prospectus as Annex D. The adoption of the amended Articles of Association is a condition to completion of the merger. In the event this proposal is approved by Allied World shareholders but the merger is not completed, the TransAllied Articles will not become effective.
 
Approval of the amendment to the articles to change Allied World’s name to “TransAllied Group Holdings, AG” requires a majority of the votes cast voting in favor of such proposal at the Allied World Special Shareholder Meeting where holders of at least 50% of the total outstanding Allied World shares are represented and voting, and who are entitled to vote on such proposal. Abstentions and broker non-votes, which are described below, will not be considered votes cast and will have no effect on these proposals, assuming a quorum is present.
 
The Allied World board of directors unanimously recommends a vote “FOR” the proposal to approve the amendment to the Allied World Articles to change Allied World’s name to “TransAllied Group Holdings, AG”.

CAPITAL REDUCTION
 
Allied World seeks approval of a proposal to effect a capital reduction to allow for the payment of a dividend to the combined company’s shareholders. Swiss law requires that dividends and distributions through a reduction in par value be approved by shareholders. At Allied World’s Annual Shareholder Meeting on May 5, 2011, Allied World’s shareholders approved the proposal that, in lieu of an ordinary dividend, a distribution in the aggregate amount of $1.50 per Allied World Share be paid through a reduction in par value because payments of amounts in reduction of share capital are not subject to the normal Swiss withholding tax on dividends. Swiss law also requires par value reductions to be in CHF, and accordingly the par value of Allied World shares and Allied World non-voting shares are expressed in CHF in the Allied World Articles. Further, the Allied World Articles and Swiss law require that a reduction in capital is approved by the shareholders holding a majority of the votes cast at the Allied World Special Shareholder Meeting.
 
General Explanation of the Dividend/Capital Reduction
 
At Allied World’s Annual Shareholder Meeting on May 5, 2011, the Allied World shareholders approved a proposal to pay dividends in the form of a distribution by way of par value reductions. The aggregate reduction amount will be paid to Allied World shareholders in four quarterly installments of $0.375 per share (the “May 2011 Resolutions”). Prior to the closing of the merger, which the parties expect to occur in the fourth quarter of 2011, it is anticipated that Allied World will distribute the first of these dividends on August 5, 2011 to shareholders of record on July 27, 2011 and expects to pay the second of these quarterly dividends in October 2011 prior to the closing of the merger.
 
Under Swiss law, a corporation is under the duty to treat all shareholders equally. Hence, following the expected closing of the merger, Allied World (re-named TransAllied following the closing of the merger) will seek to pay the third and fourth installments of its quarterly dividend to the combined company’s shareholders. Because the merger will result in the issuance of a significant number of new shares to the former shareholders of Transatlantic, the aggregate reduction amount necessary to pay a $0.375 per share quarterly dividend will increase significantly. The purpose of this proposal is to approve an aggregate reduction amount such that TransAllied will be able to pay the remaining two installments of a $0.375 per share dividend to the combined company’s shareholders. TransAllied would expect to make these payments in January 2012 and April 2012.
 
Any declaration and payment of dividends by Allied World (or TransAllied following the merger) will depend upon Allied World’s (or TransAllied’s) results of operations, financial condition and cash requirements, and will be subject to Swiss law and other related factors described in Allied World’s proxy statement for its Annual Shareholder Meeting in 2011.
 
For purposes of Swiss corporate law, the May 2011 Resolutions regarding the capital reduction need to be cancelled after the payment of the second installment scheduled for October 2011 and replaced by new resolutions that will ensure that the combined company’s shareholders are treated equally with respect to the payment of the dividend through a reduction in par value. Under the assumption that the combined company’s shareholders will be entitled to receive the third and the fourth installment of the quarterly dividend, the agenda item below calls for a par value reduction in an aggregate amount of CHF           (the “Base Dividend”), payable in two installments of CHF           each. If at the time of the Allied World Special Shareholder Meeting more or less than two partial par value reductions based on the May 2011 Resolutions have already been effected, the resolutions described below will be amended in order to take into account these changed circumstances.
 
Agenda Item
 
It is proposed that the May 2011 Resolutions be cancelled insofar as they have not already been completed as of the day immediately following the payment of the second installment provided therein.
 
Based on a report in accordance with Article 732 paragraph 2 of the Swiss Code of Obligations to be provided by Deloitte AG, as an auditor supervised by the Swiss authorities, it is proposed that the Allied World shareholders voting (in person or by proxy) at the Allied World Special Shareholder Meeting approve

Table of Contents

the following dividend in the form of a distribution by way of a par value reduction. Such resolutions shall become effective on the day immediately following the payment of the second installment provided in the May 2011 Resolutions. Pursuant to Swiss law, Allied World is required to submit to the Allied World shareholders for approval both the English and the (authoritative) German versions of the proposed amendments to the Allied World Articles:
 
1. The capital of Allied World (renamed TransAllied following the closing of the merger) in the aggregate amount of CHF            (after the first and second partial par value reductions pursuant to the May 2011 Resolutions) shall be reduced by an amount of CHF            (the “Aggregate Distribution Amount”) to CHF            (i.e., the share capital of CHF            (after the first and second partial par value reductions pursuant to the May 2011 Resolutions) shall be reduced by an amount of CHF            to CHF           and the participation capital of CHF            (after the first and second partial par value reductions pursuant to the May 2011 Resolutions) shall be reduced by the amount of CHF            to CHF           ).
 
2. Based on the report of the auditor dated        , 2011, it is recorded that the claims of the creditors of the Allied World (TransAllied following the merger) are fully covered even after taking into account the Partial Par Value Reductions (as defined below).
 
3. The capital reduction shall be executed as follows:
 
i. The capital reduction shall occur by reducing the par value per Allied World share and Allied World non-voting share from CHF            (i.e., after the first and second partial par value reductions pursuant to the May 2011 Resolutions) by CHF            (“Aggregate Reduction Amount”) to CHF           in two steps (each, a “Partial Par Value Reduction”): (1) for the first partial par value reduction from CHF           by CHF            to CHF           by the end of December 2011 (“first Partial Par Value Reduction”); and (2) for the second partial par value reduction from CHF           by CHF           to CHF            by the end of April 2012 (“second Partial Par Value Reduction”).
 
ii. The Aggregate Reduction Amount shall be repaid to the Allied World shareholders (TransAllied following the merger) in installments of CHF           in January 2012 and CHF            in April 2012 per Allied World share and Allied World non-voting shares.
 
iii. At each Partial Par Value Reduction an updated report in accordance with Article 732 paragraph 2 of the Swiss Code of Obligations by Deloitte AG, an audit company under oversight of the Swiss authorities shall be prepared (an “Updated Report”).
 
iv. The Allied World board of directors is only authorized to repay a Partial Par Value Reduction amount in the event the Updated Report confirms that the claims of creditors are fully covered in spite of the Partial Par Value Reduction.
 
v. In addition, under Swiss law, upon satisfaction of all legal requirements (including shareholder approval of a par value reduction as described in this proposal), Allied World will be required to submit an application to the Commercial Register in the Canton of Zug to register each applicable par value reduction. Without effective registration of the applicable par value reduction with the Commercial Register in the Canton of Zug, Allied World will not be able to proceed with the payment of any installment of the dividend as described in this proposal. Allied World cannot assure you that the Commercial Register in the Canton of Zug will approve the registration of any applicable par value reduction.
 
4. The Partial Par Value Reduction amount of CHF           per Allied World share and Allied World non-voting share (the “Distribution Amount”) pursuant to paragraph 3(i) and (ii) equals USD 0.375 (the “U.S. Dollar Amount”) based on a USD/CHF exchange ratio of CHF            (rounded down to the next whole cent) per $1 (being the Foreign Exchange Rate). The Distribution Amount and the


108


Table of Contents

Aggregate Distribution Amount pursuant to paragraph 1 are subject to the following adjustments as a result of USD/CHF currency fluctuations:
 
i. The Distribution Amount is to be adjusted as a result of currency fluctuations such that each Allied World share and Allied World non-voting share Partial Par Value Reduction amount shall equal an amount calculated as follows (rounded down to the next whole cent):
 
Distribution Amount = U.S. Dollar Amount x USD/CHF currency exchange ratio as published in The Wall Street Journal on December 19, 2011 for the first Partial Par Value Reduction and on March 19, 2012, for the second Partial Par Value Reduction.
 
If as a result of one or several adjustments the Aggregate Distribution Amount would otherwise be increased by more than CHF            (corresponding to 50% of the Aggregate Distribution Amount set forth in paragraph 1, rounded to the nearest cent), the adjustment is limited such that the aggregate increase to the Aggregate Distribution Amount rounded to the nearest cent equals CHF           per Allied voting share and Allied non-voting share.
 
ii. The Aggregate Distribution Amount pursuant to paragraph 1 shall be adjusted as follows:
 
Sum of the two Distribution Amounts (adjusted pursuant to Section 4(i)) x number of Allied World shares and Allied World non-voting shares registered in the Commercial Register of the Canton of Zug as issued and outstanding on the date of the registration of the respective Partial Par Value Reduction).
 
5. The Aggregate Distribution Amount pursuant to paragraph 1 (as adjusted pursuant to paragraph 4 (ii)) shall be increased by par value reductions on Allied World shares that are issued (i) in the course of ordinary capital increases, particularly in relation to the merger, (ii) from authorized share capital and (iii) from conditional share capital after the Allied World Special Shareholder Meeting but before the date of the registration in the Commercial Register of the respective Partial Par Value Reductions (this applies also to shares issued from conditional share capital that have not been registered in the Commercial Register of the Canton of Zug at such date). In the case of such capital increases the maximum amount set forth in paragraph 4 (i) shall also be increased so that it corresponds to 50% of the increased Aggregate Distribution Amount but shall not be higher than CHF           .
 
6. The general meeting acknowledges that the report of the auditor dated                    , has been prepared on the basis of (i) the maximum possible increase provided under paragraphs 4 and 5, particularly taking into account the maximum possible increase due to the increase of the ordinary share capital pursuant to article 3a(a) of the Allied World Articles in relation to the merger, and that (ii) all Allied World shares and Allied World non-voting shares have been issued out of conditional share capital and the authorized share capital post merger and therefore refers to a maximum amount of CHF           .
 
7. The Allied World board of directors is instructed to determine the procedure for the payment of the Distribution Amounts.

It is not expected that any of the nominees will become unavailable for election as a director but, if any nominee should become unavailable prior to the meeting, proxies will be voted for such persons as the Allied World board of directors shall recommend.
 
Allied World requires that a majority of its directors meet the criteria for independence under applicable law and the rules of the NYSE. The Allied World board of directors has adopted a policy to assist it and the Nominating & Corporate Governance Committee in their determination as to whether a nominee or director qualifies as independent. This policy contains categorical standards for determining independence and includes the independence standards required by the SEC and the NYSE as well as standards published by institutional investor groups and other corporate governance experts. In making its determination of independence, the Allied World board of directors applied these standards for director independence and determined that no material relationship existed between Allied World and these directors. A copy of the Allied World board policy on director independence was attached as an appendix to Allied World’s Proxy Statement filed with the SEC on March 20, 2009.
 
Approval of the proposal to elect each of the directors requires a majority of the votes cast voting in favor of such proposal at the Allied World Special Shareholder Meeting where holders of at least 50% of the total outstanding Allied World shares are represented and voting and who are entitled to vote on such proposal. Abstentions and broker non-votes, which are described below, will not be considered votes cast and will have no effect on these proposals, assuming a quorum is present.
 
The Allied World board of directors unanimously recommends a vote “FOR” the election of the named directors to hold office commencing upon the completion of the merger.

TRANSALLIED GROUP HOLDINGS, AG
FOURTH AMENDED AND RESTATED 2004 STOCK INCENTIVE PLAN
 
The Allied World board of directors proposes approval of a fourth amendment to and restatement of the Allied World Assurance Company Holdings, AG Third Amended and Restated 2004 Stock Incentive Plan. Allied World’s board of directors unanimously approved the Fourth Amended and Restated 2004 Stock Incentive Plan (which is referred to as the “Amended Plan” for purposes of this proposal only) on          , 2011, and recommends that Allied World’s shareholders approve and adopt the Amended Plan. If approved by the Allied World’s shareholders, the Amended Plan will become effective upon, and subject to, the closing of the merger.
 
On December 1, 2010, in connection with and pursuant to Allied World’s redomestication, Allied World assumed the Allied World Assurance Company Holdings, Ltd Second Amended and Restated 2004 Stock Incentive Plan from Allied World Assurance Company Holdings, Ltd, the former publicly-traded Bermuda holding company, and amended and restated the Second Amended and Restated 2004 Stock Incentive Plan and renamed it the Allied World Assurance Company Holdings, AG Third Amended and Restated 2004 Stock Incentive Plan (which is referred to as the “Current Plan” for purposes of this proposal only) to reflect such assumption.
 
Allied World’s board of directors recommends approval of the Amended Plan to:
 
  •  Increase by 2,000,000 shares (from 2,000,000 to 4,000,000) the total number of registered shares that may be issued under the Current Plan;
 
  •  Extend the termination date from May 8, 2018 to          , 2021, after which date no awards may be granted;
 
  •  Replace references to Allied World Assurance Company Holdings, AG with references to TransAllied Group Holdings, AG and references to Allied World registered shares with references to TransAllied Group Holdings, AG registered shares; and
 
  •  Permit the grant of performance-based awards that qualify as “qualified performance-based compensation” within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)”). Section 162(m) generally disallows a tax deduction to public companies for compensation in excess of $1,000,000 paid to the chief executive officer and to certain other executive officers whose compensation is required to be reported to pursuant to the Exchange Act by reason of being among the four most highly paid executive officers. The Amended Plan is designed to qualify performance-based awards as “qualified performance-based compensation” to ensure that the tax deduction is available to the combined company and its subsidiaries.
 
The Allied World board of directors adopted this amendment in order to ensure that the combined company can continue to grant equity-based awards following the completion of the proposed merger at levels determined appropriate by the combined company’s board of directors or a committee thereof (the “committee”). As of June 30, 2011, awards covering an aggregate of           registered shares were outstanding under the Current Plan, and only           Allied World shares (plus Allied World shares that may be returned to the Current Plan in the future as a result of terminations or expirations of awards or Allied World’s reacquisition of registered shares) remained available for grant under the Current Plan. Subject to Allied World’s shareholders approving this proposal, an aggregate of           Allied World shares will be reserved for issuance under the Amended Plan.
 
The following summary of the Amended Plan is qualified in its entirety by express reference to the text of the Amended Plan, a copy of which is attached as Annex E to this joint proxy statement/prospectus. For more information about Allied World’s Current Plan, please see Item 15 of Allied World’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010 and Note 12 to Allied World’s Consolidated Financial Statements included in Allied World’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010.
 
The changes discussed above are the only changes being proposed to the Current Plan.

Table of Contents

General
 
The purposes of the Amended Plan are to attract, retain, and motivate officers, directors, employees (including prospective employees), consultants, and others who may perform services for the combined company, to compensate them for their contributions to the long-term growth and profits of the combined company and to encourage them to acquire a proprietary interest in the success of the combined company. Allied World’s board of directors believes that the Amended Plan furthers these purposes by making available sufficient shares to permit future awards by the committee as a part of the combined company’s compensation program and believes that the Amended Plan is important to the success of the combined company.
 
As of June 30, 2011, approximately 690 individuals would be eligible to participate in the Amended Plan. The closing price of Allied World’s shares on the NYSE on June 30, 2011, was $57.58 per share.
 
Administration
 
As with the Current Plan, the Amended Plan will be administered by the committee, which, pursuant to the proposed amendment, will be composed of not less than two “outside directors” (within the meaning of Section 162(m)) and will have the authority to establish rules and regulations for the administration of the Amended Plan; to take any action in connection with the Amended Plan that it deems necessary or advisable; to determine who shall receive awards and the terms, conditions, restrictions, and performance goals relating to any award; to amend any outstanding awards; to determine whether, to what extent, and under what circumstances and methods awards may be settled, cancelled, forfeited or suspended; to determine whether awards may be settled in Allied World shares or cash or other property; to determine performance goals no later than such time as is required to ensure that an underlying award which is intended to comply with the requirements of Section 162(m), so complies, and to determine whether amounts payable under an award may be deferred. The determination of the committee on all matters relating to the Amended Plan will be final and binding.
 
Awards; Adjustments
 
As with the Current Plan, the Amended Plan provides for the grant of restricted registered shares, restricted share units, dividend equivalent rights, and other equity-based or equity-related awards. The terms and conditions of any such awards granted under the Amended Plan are set out in award agreements between the combined company and the individuals receiving such awards. No options to purchase Allied World shares may be granted under the Amended Plan.
 
Restricted Allied World Shares.  The committee may grant or offer for sale restricted registered shares, which shall be subject to a minimum vesting period of one year from the date of grant or purchase, except in the case of an earlier termination of employment due to death, disability, retirement at or after age 65, or a change in control of the combined company, or, pursuant to the proposed amendment, with respect to an award that the committee determines is performance-based.
 
Restricted Share Units.  A restricted share unit entitles the holder to one Allied World share (or cash or other property having the same value as one Allied World share) on the applicable date of settlement, subject to a minimum vesting period of one year from the date of grant or purchase, except in the case of an earlier termination of employment due to death, disability, or retirement at or after age 65, or a change in control of the combined company, or, pursuant to the proposed amendment, with respect to an award that the committee determines is performance-based. Holders of restricted share units are general unsecured creditors of the combined company until settlement of such units.
 
Dividend Equivalent Rights.  The committee may include with any award under the Amended Plan a dividend equivalent right entitling the grantee to receive amounts equal to all or a portion of the dividends that would be paid on the Allied World shares covered by such award if such shares had been held by the award-holder at the time of such dividend. Dividend equivalents may be paid to a grantee in cash, registered shares, or such other form as determined by the committee at the time of grant. Holders of dividend equivalent units are general unsecured creditors of the combined company until settlement of such units.

Performance Awards.  Pursuant to the proposed amendment, the committee may determine that the grant, vesting, or settlement of an award granted under the Amended Plan may be subject to the attainment of one or more performance goals. The performance metrics that may be applied to an award intended to qualify as “performance-based compensation” for purposes of Section 162(m) granted under the Amended Plan include: (i) consolidated earnings before or after taxes (including earnings before interest, taxes, depreciation and amortization); (ii) net income; (iii) operating income; (iv) earnings per share; (v) book value per share; (vi) return on shareholders’ equity; (vii) return on investment; (viii) stock price; (ix) improvements in capital structure; (x) revenue or sales; and (xi) total return to shareholders.
 
Other Equity-Based Awards.  The committee may grant other types of equity-based or equity-related awards (including the grant or offer for sale of unrestricted Allied World shares), subject to the terms and conditions as the committee shall determine.
 
As with the Current Plan, under the Amended Plan, the committee will have the authority to make appropriate adjustments to the number of Allied World shares authorized for issuance under the Amended Plan, the number of Allied World shares covered by each outstanding award and the type of property to which an award is subject, and, pursuant to the proposed amendment, the committee will also have the authority to adjust any applicable performance measures under any award, in each case in such manner as it deems appropriate to preserve the benefits intended to be made available to grantees of awards for any changes to the Allied World shares by reason of capital adjustments, such as stock splits and recapitalizations. In the event of a merger, amalgamation, consolidation, reorganization, liquidation or sale of a majority of the combined company’s securities, the committee will have the discretion to provide, as an alternative to the adjustment described above, for the accelerated vesting of awards prior to such an event or the cancellation of awards in exchange for a payment based on the per-share consideration being paid in connection with the event. The Amended Plan provides that adjustments to awards that qualify as “qualified performance-based compensation” under Section 162(m) may not be made in a manner that would cause the modified award to result in a loss of deduction under Section 162(m), unless the committee specifically determines otherwise.
 
Shares Subject to the Amended Plan
 
Subject to Allied World’s shareholders approving this proposal, the total number of registered shares reserved for issuance under the Amended Plan will be 4,000,000. During any time that the combined company is subject to Section 162(m) of the Code, the maximum number of Allied World shares with respect to which awards may be granted to any individual in any one year shall not exceed the maximum number of registered shares available for issue under the Amended Plan. Allied World shares granted pursuant to the Amended Plan may be authorized but unissued Allied World shares or authorized and issued Allied World shares acquired by the combined company for the purposes of the Amended Plan.
 
Amendment and Termination
 
Except as otherwise provided in an award agreement, the combined company’s board of directors retains the right to suspend, discontinue, revise, or amend the Amended Plan without any grantee’s consent, including in any manner that may adversely affect a grantee’s rights with respect to an outstanding award. While the combined company’s board of directors retains the right to terminate the Amended Plan at any time as described above, in any case, the Amended Plan will, subject to Allied World’s shareholders approving this proposal, terminate on          , 2021.
 
Nonassignability; No Hedging
 
As with the Current Plan, no award to any person under the Amended Plan may be assigned, transferred, or hedged in any manner (except as expressly approved by the committee), other than by will or by the laws of descent and distribution, and all such awards shall be exercisable during the life of the grantee only by the grantee or the grantee’s legal representative. Any assignment or transfer in violation of the applicable provisions of the Amended Plan shall be null and void, and any award that is hedged in any manner shall immediately be forfeited.

New Plan Benefits
 
The grant of awards under the Amended Plan is entirely within the discretion of the committee, and Allied World cannot forecast the extent to which such grants will be made in the future. Therefore, Allied World has omitted the tabular disclosure of the benefits or amounts allocated under the Amended Plan.

Transatlantic’s 2000 Stock Option Plan, 2003 Stock Incentive Plan, 2008 Non-Employee Directors’ Stock Plan, and 2009 Long Term Equity Incentive Plan were previously approved by Transatlantic’s shareholders, and future grants under these plans will only be made to persons who were employees of Transatlantic prior to the merger. The LTIP provides for performance-based equity awards representing the right to receive a number of Allied World shares in the future, based upon the achievement of established performance criteria during the applicable three-year performance period.

Pursuant to NYSE guidelines, the approval of the Stock Incentive Plan proposal, specifically the increase of the shares reserved for issuance thereunder, requires the affirmative vote of the holders of a majority of shares entitled to vote on the proposal and present in person or represented by proxy at the Allied World Special Shareholder Meeting, provided that the total votes cast on this proposal represent over 50% of the outstanding Allied World shares entitled to vote on this proposal. Votes “for,” votes “against” and abstentions count as votes cast, while broker non-votes do not count as votes cast for this purpose. All outstanding Allied World shares, including broker non-votes, count as shares entitled to vote. Thus, the total sum of votes “for,” plus votes “against,” plus abstentions, which we refer to as the “NYSE votes cast”, must be greater than 50% of the total outstanding Allied World shares. The number of votes “for” the proposal must be greater than 50% of the NYSE votes cast.
 
The Allied World board of directors unanimously recommends a vote “FOR” the proposal to approve the adoption of the Amended Plan effective upon completion of the merger.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES
 
The following is a summary of the material U.S. federal income tax consequences of the merger. This discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations, judicial authorities, published positions of the Internal Revenue Service (the “IRS”), and other applicable authorities, all as currently in effect and all of which are subject to change or differing interpretations, possibly with retroactive effect. This discussion is limited to U.S. holders (as defined below) that hold their shares of Transatlantic common stock as capital assets within the meaning of Section 1221 of the Code (generally, assets held for investment). This discussion does not address the tax consequences applicable to Transatlantic stockholders that are not U.S. holders, nor does it address all of the tax consequences that may be relevant to any particular U.S. holder or U.S. holders that are subject to special treatment under U.S. federal income tax laws, including, without limitation:
 
  •  banks, insurance companies or other financial institutions;
 
  •  broker-dealers;
 
  •  traders;
 
  •  certain U.S. expatriates;
 
  •  tax-exempt organizations;
 
  •  pass-through entities and persons that are investors in a pass-through entity;
 
  •  persons that are subject to alternative minimum tax;
 
  •  persons that hold their shares of common stock as a position in a “straddle” or as part of a “hedging” or “conversion” transaction;
 
  •  persons deemed to sell their shares of Transatlantic common stock under the constructive sale provisions of the Code;
 
  •  persons that have a functional currency other than the U.S. dollar; or
 
  •  persons that acquired their shares of Transatlantic common stock upon the exercise of stock options or otherwise as compensation.
 
If a partnership or other entity or arrangement treated as a partnership for U.S. federal income tax purposes holds shares of Transatlantic common stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships holding shares of Transatlantic common stock and partners in such partnerships should consult their tax advisors about the tax consequences of the merger to them.
 
This discussion does not address the tax consequences of the merger under state, local or foreign tax laws. This discussion also does not address the tax consequences of any transaction other than the merger, nor does it address the tax consequences of the ownership or disposition of Allied World shares acquired in the merger.
 
TRANSATLANTIC STOCKHOLDERS ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISORS AS TO THE TAX CONSEQUENCES OF THE MERGER IN THEIR PARTICULAR CIRCUMSTANCES, INCLUDING THE APPLICABILITY AND EFFECT OF U.S. FEDERAL (INCLUDING THE ALTERNATIVE MINIMUM TAX), STATE, LOCAL OR FOREIGN AND OTHER TAX LAWS AND OF CHANGES IN THOSE LAWS.
 
For purposes of this discussion, a “U.S. holder” means a holder of Transatlantic common stock that is, for U.S. federal income tax purposes:
 
  •  an individual that is a citizen or resident of the United States;
 
  •  a corporation or an entity treated as a corporation created or organized in, or under the laws of, the United States, any state thereof or the District of Columbia;


121


Table of Contents

 
  •  an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or
 
  •  a trust (i) the administration over which a United States court can exercise primary supervision and the substantial decisions of which one or more United States persons have the authority to control or (ii) that has a valid election in effect to be treated as a United States person.
 
Consequences of the Merger
 
The receipt of Allied World shares in exchange for shares of Transatlantic common stock pursuant to the merger will be a taxable transaction for U.S. federal income tax purposes. In general, a U.S. holder that receives Allied World shares in exchange for shares of Transatlantic common stock pursuant to the merger will recognize capital gain or loss for U.S. federal income tax purposes equal to the difference, if any, between (i) the sum of the fair market value of the Allied World shares received as of the effective time of the merger and the amount of cash, if any, received in lieu of fractional shares and (ii) the holder’s adjusted tax basis in the shares of Transatlantic common stock exchanged for the Allied World shares pursuant to the merger. Any gain or loss would be long-term capital gain or loss if the holder’s holding period in the shares of Transatlantic common stock exceeds one year at the effective time of the merger. Long-term capital gains of noncorporate U.S. holders (including individuals) generally are eligible for preferential rates of U.S. federal income tax. There are limitations on the deductibility of capital losses under the Code. No gain or loss will be recognized by Allied World shareholders as a consequence of the merger.
 
A U.S. holder’s tax basis in Allied World shares received in the merger will equal the fair market value of the shares as of the effective time of the merger. A U.S. holder’s holding period in the Allied World shares received in the merger will begin on the day after the completion of the merger.
 
Backup Withholding
 
Backup withholding, currently at a rate of 28%, may apply to payments made in connection with the merger. Backup withholding will not apply, however, to a holder of Transatlantic common stock that (1) furnishes a correct taxpayer identification number and certifies that it is not subject to backup withholding on the substitute IRS Form W-9 included in the letter of transmittal to be delivered to holders of Transatlantic common stock prior to completion of the merger, (2) provides a certification of non-U.S. status on the applicable IRS Form W-8 (typically IRS Form W-8BEN) or appropriate successor form or (3) is otherwise exempt from backup withholding. Any amounts withheld under the backup withholding rules may be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided the required information is timely furnished to the IRS. Please consult your own tax advisor to see if you qualify for exemption from backup withholding and, if so, to understand the procedure for obtaining that exemption.
 
THE FOREGOING DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OF THE POTENTIAL TAX CONSIDERATIONS RELATING TO THE MERGER, AND IS NOT TAX ADVICE. THEREFORE, TRANSATLANTIC STOCKHOLDERS ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER IN THEIR PARTICULAR SITUATION, INCLUDING THE APPLICABILITY OF U.S. FEDERAL (INCLUDING THE ALTERNATIVE MINIMUM TAX), STATE, OR LOCAL, FOREIGN AND OTHER TAX LAWS AND OF CHANGES IN THOSE LAWS.

ACCOUNTING TREATMENT
 
Each of Transatlantic and Allied World prepares its financial statements in accordance with GAAP. The merger will be accounted for using the acquisition method of accounting with Transatlantic treated as the accounting acquirer of Allied World. Accordingly, the assets, liabilities and commitments of Allied World, the accounting acquiree, are adjusted to their estimated fair value. Under the acquisition method of accounting, intangible assets are amortized over their remaining useful lives and tested for impairment at least annually.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION
 
The unaudited pro forma condensed consolidated financial information (“pro forma financial information”) that follows combines the historical accounts of Transatlantic and Allied World. The Pro Forma Condensed Consolidated Balance Sheet as of March 31, 2011 shows the consolidated financial position of Transatlantic and Allied World as if the merger of the two companies had occurred on that date. The Pro Forma Condensed Consolidated Statements of Operations for the year ended December 31, 2010 and for the three months ended March 31, 2011 reflect the companies’ consolidated results as if the merger had occurred as of January 1, 2010. The historical consolidated financial information has been adjusted to reflect factually supportable items that are directly attributable to the merger, and with respect to the statement of operations only, expected to have a continuing impact on consolidated results of operations. These pro forma financial statements should be read in conjunction with:
 
  •  The accompanying notes to the pro forma financial statements;
 
  •  Transatlantic’s and Allied World’s separate unaudited historical condensed consolidated financial statements and notes as of and for the three months ended March 31, 2011 included in their respective March 31, 2011 Quarterly Reports on Form 10-Q; and
 
  •  Transatlantic’s and Allied World’s separate audited historical consolidated financial statements and notes as of and for the year ended December 31, 2010 included in their respective 2010 Annual Reports on Form 10-K.
 
The pro forma financial information has been prepared for illustrative purposes only. The pro forma adjustments are based on estimates using information available at this time. The pro forma financial information is not necessarily indicative of what the financial position or results of operations actually would have been had the merger been completed at the dates indicated, and include pro forma adjustments which are preliminary and may be revised. There can be no assurance that such revisions will not result in material changes. The financial position and results of operations shown therein are not necessarily indicative of what the past financial position and results of operations of the combined companies would have been nor indicative of the financial position and results of operations of the post-merger periods. The pro forma financial information does not give consideration to the impact of possible revenue enhancements, expense efficiencies, synergies, strategy modifications, asset dispositions or other actions that may result from the merger.
 
The pro forma financial information has been prepared using the acquisition method of accounting with Transatlantic treated as the accounting acquirer. Accordingly, the assets, liabilities and commitments of Allied World, the accounting acquiree, are adjusted to their estimated March 31, 2011 fair values. The estimates of fair value are preliminary and are dependent upon certain valuations and other studies that have not progressed to a stage where there is sufficient information to make a definitive valuation. Accordingly, actual adjustments to the Consolidated Balance Sheet and Statements of Operations will differ, perhaps materially, from those reflected in the pro forma financial information because the assets and liabilities of Allied World will be recorded at their respective fair values on the date the merger is consummated and the preliminary assumptions used to estimate these fair values may change between now and the completion of the merger.

Notes to the Pro Forma Condensed
Consolidated Financial Information
(Unaudited)
 
Note 1 — Pro Forma Basis of Presentation
 
On June 12, 2011, Transatlantic and Allied World agreed to a “merger of equals” business combination (the “merger”) and have entered into an Agreement and Plan of Merger, as further discussed herein.
 
The unaudited Pro Forma Condensed Consolidated Balance Sheet as of March 31, 2011 has been prepared to illustrate the pro forma effects of the merger as if it had occurred on March 31, 2011. The unaudited Pro Forma Condensed Consolidated Statements of Operations for the three months ended March 31, 2011 and for the twelve months ended December 31, 2010 have been prepared to illustrate the pro forma effects of the merger as if it had occurred at January 1, 2010.
 
The pro forma financial information has been prepared using the acquisition method of accounting under accounting principles generally accepted in the United States of America. Based on the relative voting interests of Transatlantic stockholders and Allied World shareholders, the composition of the combined company’s board of directors, senior management of the merged entity, the relative size of Transatlantic’s and Allied World’s shareholders’ equity, revenue and market capitalization, and other factors, it was determined that Transatlantic is the acquiring entity for accounting purposes. Accordingly, under acquisition method accounting, the assets, liabilities and commitments of Allied World, the accounting acquiree, are adjusted to their fair value. For purposes of the pro forma financial information, preliminary consideration has also been given to the impact of conforming Allied World’s accounting policies to those of Transatlantic. The pro forma financial information does not give consideration to the impact of possible revenue enhancements, expense efficiencies, synergies, strategy modifications, asset dispositions or other actions. Also, possible adjustments related to restructuring charges are yet to be determined and are not reflected in the pro forma financial information.
 
The preliminary unaudited pro forma adjustments represent estimates based on information available at this time. Actual adjustments to the Consolidated Balance Sheet and Statements of Operations will differ, perhaps materially, from those reflected in the pro forma financial information because the assets and liabilities of Allied World will be recorded at their respective fair values on the date the merger is consummated and the preliminary assumptions used to estimate these fair values may change between now and the completion of the merger.
 
The pro forma financial information included herein is subject to other updates as additional information becomes available and as additional analyses are performed. The final acquisition accounting will be determined after the merger is consummated and after completion of a thorough analysis to determine the fair values of Allied World’s tangible and identifiable intangible assets and liabilities. Accordingly, the final acquisition method accounting adjustments, including those needed to conform Allied World’s accounting policies to those of Transatlantic, could be materially different from the preliminary unaudited pro forma adjustments presented herein. Any increase or decrease in the fair value of Allied World’s assets, liabilities, commitments, contracts and other items as compared to the information shown herein will change the amount of gain on bargain purchase and may impact the consolidated statement of operations due to adjustments in yield and/or amortization or accretion related to the adjusted assets or liabilities.
 
Note 2 — Pro Forma Adjustments
 
Upon completion of the merger, Transatlantic stockholders will receive 0.88 Allied World shares for each share of Transatlantic common stock that they own. This exchange ratio is fixed and will not be adjusted to reflect stock price changes prior to the closing of the merger.
 
The pro forma financial information is not necessarily indicative of what the financial position or results of operations actually would have been had the merger been completed at the dates indicated and include adjustments which are preliminary and may be revised. There can be no assurance that such revisions will not result in material changes. The financial position and results of operations shown therein are not necessarily

Consolidated Financial Information — (Continued)
 
indicative of what the past financial position and results of operations of the combined companies would have been nor indicative of the financial position and results of operations of the post-merger periods. The pro forma financial information does not give consideration to the impact of possible revenue enhancements, expense efficiencies, synergies, strategy modifications, asset dispositions or other actions that may result from the merger.
 
The following pro forma adjustments result from accounting for the merger, including the determination of fair value of the assets, liabilities and commitments which Transatlantic, as the acquirer for accounting purposes, acquired from Allied World. The descriptions related to these preliminary adjustments are as follows (in thousands of U.S. dollars):

The tax impact of pro forma adjustments is estimated in the aggregate on each pro forma financial statement based on the applicable tax impact on the entity that is expected to sustain the related pre-tax charge or benefit. The pro forma tax adjustments, however, do not reflect the potential tax impact that the revised legal structure or other post-merger actions may have on taxes incurred after the merger.
 
Following the merger, the merging entities anticipate that the relationship of the combined companies’ gross premiums written to net premiums written and its practices related to the purchase of reinsurance protection will more closely align with the gross to net premiums written relationship and practices presently followed by Transatlantic. Such practices govern the level of exposures retained, type and financial standing of approved reinsurers and nature of reinsurance protection purchased. Given the enhanced capital base of the combined companies, it is expected that there will be a reduced need for the combined companies to purchase ceded reinsurance coverage in the future.
 
In the accompanying Pro Forma Condensed Consolidated Balance Sheet, the preliminary estimate of the purchase price has been calculated by using the closing quoted market price per share of Transatlantic common stock on June 30, 2011. This amount of consideration will be adjusted subsequently to reflect the closing quoted market price of Transatlantic common stock as of the merger’s effective date.

The preliminary estimated gain on bargain purchase upon closing of the merger is reflected as an increase in retained earnings in the pro forma balance sheet. The preliminary gain on bargain purchase results from the acquisition date fair value of Allied World’s identifiable net assets acquired exceeding the estimated purchase price. This bargain purchase determination is consistent with the fact that in recent periods, Allied World’s shares, as well as shares of certain other insurance and reinsurance companies, including Transatlantic, have traded at a significant discount to book value per common share. The preliminary gain on bargain purchase will be adjusted based upon the final accounting as of the closing date of the merger.
 
The price of Transatlantic common stock used in preparing the pro forma financial information was $49.01, based on the closing price of Transatlantic common stock on June 30, 2011. The effect of an increase (decrease) of $1.00 per share of the price of Transatlantic common stock would be to decrease (increase) the pro forma gain on bargain purchase and to increase (decrease) additional paid-in capital by $43 million, reflecting the increase (decrease) in the estimated purchase price. There would be no impact on the pro forma book value per share and pro forma basic and diluted net (loss) income per share.
 
As discussed earlier, pro forma adjustments are based on certain estimates and assumptions made as of the date of the pro forma financial information. The actual adjustments will depend on a number of factors, including changes in the estimated fair value of Allied World’s assets, liability and commitments and operating results of Allied World between March 31, 2011 and the effective date of the merger. Transatlantic expects to make such adjustments at the effective date of the merger. These adjustments are likely to be different from the adjustments made to prepare the pro forma financial information and such differences may be material.

Note 3 — Net (Loss) Income per Common Share
 
Pro forma net (loss) income per common share for the three months ended March 31, 2011 and for the year ended December 31, 2010 have been calculated based on the estimated weighted average number of common shares outstanding on a pro forma basis. The pro forma weighted average number of common shares outstanding was derived using Allied World’s historical weighted average common shares outstanding and Transatlantic’s historical weighted average common shares outstanding multiplied by the exchange ratio.
 
The following table sets forth the calculation of basic and diluted pro forma net loss per common share for the three months ended March 31, 2011:

DESCRIPTION OF ALLIED WORLD SHARE CAPITAL
 
The following discussion is a summary of the terms of the capital stock of Allied World and should be read in conjunction with the section entitled “Comparison of Rights of TransAllied Shareholders and Transatlantic Stockholders” beginning on page 146. This summary is not meant to be complete and is qualified in its entirety by reference to the Swiss Federal Code of Obligations (the “Swiss Code”) and to the Allied World Articles and the organizational regulations of Allied World. You are urged to read those documents carefully. Copies of the Allied World Articles and organizational regulations of Allied World are incorporated by reference in this joint proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 159.
 
Authorized Share Capital
 
The share capital of Allied World as registered with the Swiss Commercial Register of the canton of Zug, Switzerland amounts to CHF 597,019,530, divided into 39,801,302 Allied World shares (Namenaktien) with a par value of CHF 15.00 per share and the participation capital of Allied World amounts to CHF 3,035,100 and is divided into 202,340 registered participation certificates with a par value of CHF 15.00 per participation certificate, fully paid-in. As of          , 2011, there were          Allied World shares outstanding (excluding treasury shares) and           participation certificates. Only Allied World registered shares (Namenaktien) will be issued in the merger.
 
The Allied World board of directors is authorized to issue new voting shares at any time during the two-year period ending on November 30, 2012 and thereby increase the share capital, without further shareholder approval, by a maximum amount of 20% of the share capital registered in the Swiss Commercial Register or 7,960,260 Allied World shares, par value CHF 15.00 per share. After the expiration of the initial two-year period, and each subsequent two-year period, authorized share capital will be available to the Allied World board of directors for issuance of additional Allied World shares only if the authorization is reapproved by shareholders. The Allied World Articles provide for conditional capital that allows the Allied World board of directors to authorize the issuance of up to 7,200,000 of additional Allied World shares without obtaining additional shareholder approval as follows: (i) up to a maximum amount not exceeding CHF 15,000,000 (which is equivalent to 1,000,000 Allied World shares) in connection with the exercise of conversion and/or option or warrant rights granted in connection with bonds, notes or similar instruments, issued or to be issued by Allied World or by subsidiaries of Allied World, including convertible debt instruments; (ii) up to a maximum amount not exceeding CHF 63,000,000 (which is equivalent to 4,200,000 Allied World shares) in connection with the exercise of option rights granted to any employee of Allied World or a subsidiary, and any consultant, director or other person providing services to Allied World or a subsidiary; or (iii) up to a maximum amount not exceeding CHF 30,000,000 (which is equivalent to 2,000,000 Allied World shares) in connection with the exercise of the shareholder warrant previously granted at the time of Allied World’s formation to AIG.
 
Other Classes or Series of Shares
 
The board of directors may not create shares with increased voting powers (i.e., super voting shares) or preferred stock (Vorzugsaktien). To create super-voting shares (Vorzugsaktien), a resolution of the general meeting passed by a qualified majority of at least 662/3% of the votes and a majority of the par value of the voting shares represented at the general meeting is required.
 
Voting Rights
 
Pursuant to the Allied World Articles, each Allied World voting share conveys the right to one vote. The Allied World Articles limit the voting rights of Allied World shares that are “controlled shares” of a shareholder to one vote less than 10% of the total voting rights of Allied World’s share capital as registered with the Swiss Commercial Register. Controlled shares of a shareholder consist of shares owned by the shareholder (i) directly or (ii) by application of certain constructive ownership rules. These rules are derived from constructive ownership rules contained in the Code relating to “controlled foreign corporation” status but


138


Table of Contents

are broader than the Code in that the Code distinguishes in some respects between U.S. and non-U.S. persons, while Swiss law would not support rules that discriminate based on citizenship or residence. The Allied World board of directors may waive this restriction.
 
The Allied World Articles also contain a provision regarding voting rights that is customary for Swiss companies and provides that, to be able to exercise voting rights, holders of shares must apply to Allied World for enrollment in the Allied World share register (Aktienregister) as shareholders with voting rights. Registered holders of shares may obtain the form of declaration from Continental Stock Transfer & Trust Company, Allied World’s transfer agent. If an Allied World shareholder fails to register as a shareholder with voting rights, such shareholder may not participate in or vote at Allied World general shareholders’ meetings but will be entitled to dividends, preemptive rights and liquidation proceeds. Only Allied World shareholders that are registered as shareholders with voting rights on the relevant record date are permitted to participate in and vote at a general shareholders’ meeting. The Allied World board of directors may record nominees who hold shares in their own name, but for the account of third parties, as shareholders of record in Allied World’s share register. Beneficial owners of shares who hold shares through a nominee exercise the shareholders’ rights through the intermediation of such nominee.
 
Pursuant to the Allied World Articles, Allied World shareholders generally pass resolutions and make elections at the general meeting by the affirmative vote of a simple majority of the votes cast (whereby abstentions, broker non-votes, blank or invalid ballots are disregarded for purposes of establishing the majority).
 
Supermajority Voting
 
The Swiss Code and/or the Allied World Articles require the affirmative vote of at least 662/3% of the voting rights and a majority of the par value of the voting shares, in each case as represented at a general meeting where two or more persons at the meeting representing in person or by proxy more than 50% of Allied World total outstanding registered shares throughout the meeting, to approve the following matters:
 
  •  a change of the purpose of Allied World;
 
  •  the creation of shares with privileged voting rights;
 
  •  the restriction on the transferability of voting shares or non-voting shares;
 
  •  an increase of capital, authorized or subject to a condition;
 
  •  an increase of capital out of equity against contributions in kind, or for the purpose of acquisition of assets and the granting of special benefits;
 
  •  the limitation or withdrawal of preemptive rights;
 
  •  a change in the domicile of Allied World;
 
  •  the liquidation of Allied World;
 
  •  the alleviating or withdrawal of restrictions upon the transfer of Allied World shares or Allied World non-voting shares;
 
  •  the conversion of voting shares into bearer shares and vice versa as well as the conversion of Allied World non-voting shares into Allied World shares;
 
  •  the dismissal of any member of the Allied World board of directors according to Article 705, paragraph 1 of the Swiss Code; and
 
  •  any alteration or amendment of articles 8, 14, 15 or 16 of the Allied World Articles, which relate to the voting rights of shareholders of Allied World.
 
The same supermajority voting requirements apply to resolutions in relation to transactions among corporations based on Switzerland’s Federal Act on Mergers, Demergers, Transformations and the Transfer of Assets, including a merger, demerger or conversion of a corporation (other than a cash-out or certain squeeze-


139


Table of Contents

out mergers, in which minority shareholders of the company being acquired may be compensated in a form other than through shares of the acquiring company, for instance, through cash or securities of a parent company of the acquiring company or of another company — in such a merger, an affirmative vote of 90% of the outstanding voting shares is required). Swiss law may also impose this supermajority voting requirement in connection with the sale of “all or substantially all of its assets” by Allied World. The merger will not have to be approved with a supermajority as it does not qualify as a statutory merger pursuant to the provisions of the Merger Act. However, the ordinary capital increase requires the affirmative vote of at least 662/3% of the voting rights and a majority of the par value of the voting shares, in each case, as represented at a shareholders meeting, since the increase of capital is out of equity (capital reserves).
 
Compulsory Acquisitions; Appraisal Rights
 
Business combinations and other transactions that are binding on all shareholders are governed by the Merger Act. A statutory merger or demerger requires that at least 662/3% of the voting shares and a majority of the par value of the voting shares, each as represented at the general meeting of shareholders vote in favor of the transaction. Under the Merger Act, a “demerger” may take two forms:
 
  •  a legal entity may divide all of its assets and transfer such assets to other legal entities, with the shareholders of the transferring entity receiving equity securities in the acquiring entities and the transferring entity dissolving upon deregistration in the commercial register; or
 
  •  a legal entity may transfer all or a portion of its assets to other legal entities, with the shareholders of the transferring entity receiving equity securities in the acquiring entities (in addition to the current shareholdings).
 
If a transaction under the Merger Act receives all of the necessary consents, all shareholders would be compelled to participate in the transaction. Swiss companies may be acquired by an acquirer through the direct acquisition of the share capital of the Swiss company. With respect to corporations limited by shares, such as Allied World, the Merger Act provides for the possibility of a so-called “cash-out” or “squeeze-out” merger if the acquirer controls 90% of the outstanding voting shares. In these limited circumstances, minority shareholders of the company being acquired may be compensated in a form other than through shares of the acquiring company (for instance, through cash or securities of a parent company of the acquiring company or of another company). For business combinations effected in the form of a statutory merger or demerger and subject to Swiss law, the Merger Act provides that if the equity rights have not been adequately preserved or compensation payments in the transaction are unreasonable, a shareholder may request the competent court to determine a reasonable amount of compensation.
 
In addition, under Swiss law, the sale of “all or substantially all of its assets” by Allied World may require a resolution of the general meeting of shareholders passed by holders of at least 662/3% of the voting rights and a majority of the par value of the voting shares, each as represented at the general meeting of shareholders.
 
Whether or not a shareholder resolution is required depends on the particular transaction, including whether the following test is satisfied:
 
  •  the company sells a core part of its business, without which it is economically impracticable or unreasonable to continue to operate the remaining business;
 
  •  the company’s assets, after the divestment, are not invested in accordance with the company’s statutory business purpose; and
 
  •  the proceeds of the divestment are not earmarked for reinvestment in accordance with the company’s business purpose but, instead, are intended for distribution to shareholders or for financial investments unrelated to the company’s business.
 
If all of the foregoing apply, a shareholder resolution would likely be required.

Table of Contents

 
Quorum
 
Under Swiss law, there is no mandatory quorum requirement unless set forth in a company’s articles of association (although certain actions by shareholders require the approval of a specified percentage of all voting shares, whether or not such shares are actually voted, which has the practical effect of a quorum requirement). The Allied World Articles provide for a quorum requirement the presence of two or more persons at the meeting representing in person or by proxy more than 50% of Allied World’s total outstanding Allied World shares throughout the meeting.
 
Dividends and Other Payments to Shareholders
 
Under Swiss law, dividends may be paid out only if Allied World has sufficient distributable profits from previous fiscal years or if Allied World has freely distributable reserves, each as will be presented on Allied World’s audited statutory financial statements prepared in accordance with Swiss law. Payments out of the share and participation capital (in other words, the aggregate par value of Allied World’s share and participation capital) in the form of dividends are not allowed; however, payments out of share and participation capital may be made by way of a capital reduction to achieve a similar result as the payment of dividends. The affirmative vote of shareholders holding a majority of the votes cast at a shareholder meeting must approve reserve reclassifications and distributions of dividends. The Allied World board of directors may propose to shareholders that a dividend be paid but cannot itself authorize the dividend. In addition, Allied World shareholders may propose dividends without any dividend proposal by the Allied World board of directors. Under Swiss law, upon satisfaction of all legal requirements (including shareholder approval of a par value reduction), Allied World is required to submit an application to the Swiss Commercial Register to register each applicable par value reduction. Without effective registration of the applicable par value reduction with the Swiss Commercial Register, Allied World will not be able to proceed with the payment of any installment of any dividend.
 
Under Swiss law, if the Allied World general capital reserves amount to less than 20% of the share and participation capital recorded in the Swiss Commercial Register (i.e., 20% of the aggregate par value of Allied World’s capital), then at least 5% of Allied World’s annual profit must be retained as general reserves. Swiss law permits Allied World to accrue additional general reserves. In addition, Allied World is required to create a special reserve on its audited statutory financial statements in the amount of the purchase price of voting shares and Allied World non-voting shares that Allied World or any of its subsidiaries repurchase, which amount may not be used for dividends.
 
Swiss companies generally must maintain separate audited statutory financial statements for the purpose of, among other things, determining the amounts available for the return of capital to shareholders, including by way of a distribution of dividends. Amounts available for the return of capital as indicated on Allied World’s audited statutory financial statements may be materially different from amounts reflected in Allied World’s consolidated GAAP financial statements. Allied World’s auditor must confirm that a dividend proposal made to shareholders complies with Swiss law and the Allied World Articles.
 
Allied World is required under Swiss law to declare any dividends and other capital distributions in Swiss francs. Allied World makes dividend payments to holders of its common shares in U.S. dollars. Continental Stock Transfer & Trust Company, Allied World’s transfer agent, will be responsible for paying the U.S. dollars to registered holders of Allied World shares and Allied World non-voting shares, less amounts subject to withholding for taxes. As a result, Allied World shareholders are exposed to fluctuations in the U.S. dollar — Swiss franc exchange rate between the date used for purposes of calculating the Swiss franc amount of any proposed dividend or par value reduction and the relevant payment date.
 
Pursuant to Swiss law, dividend payments, but not payments to shareholders in the form of a return of capital, are subject to Swiss withholding taxes. Any dividend payments remain subject to Swiss withholding tax, imposed on the gross amount at the current rate of 35%. The withholding tax must be borne by the shareholder. Swiss resident beneficiaries of taxable dividends are entitled to full subsequent relief of the withholding tax, either through a tax refund or through a credit against their income tax liability, if such recipients are the beneficial owners of the shares at the time such dividend payment is made and they duly


141


Table of Contents

report the gross income in their tax returns or financial statements used for tax purposes, as the case may be, and if there is no tax avoidance. Non-Swiss resident beneficiaries of dividends may be entitled to a partial or full refund of the withholding tax in accordance with any applicable double taxation convention between Switzerland and the beneficiary’s country of tax residence.
 
Any reduction of Allied World share capital recorded in the Swiss Commercial Register requires the approval of Allied World shareholders holding a majority of the shares represented at the general shareholders’ meeting. A special audit report must confirm that creditors’ claims remain fully covered despite the reduction in share capital recorded in the Swiss Commercial Register. Upon approval of the capital reduction by the general meeting of Allied World shareholders, the Allied World board of directors must give public notice of the capital reduction resolution in the Swiss Official Gazette of Commerce three times and notify creditors that they may request, within two months of the third publication, satisfaction of or security for their claims. Reduction of share and participation capital requires that Allied World’s net assets still exceed the share and participation capital and statutory reserves after a par value reduction payment to the shareholders has been made.
 
Preemptive Rights and Advance Subscription Rights
 
Under the Swiss Code, if new Allied World shares or non-voting shares are being issued, the existing shareholders or holders of non-voting shares in Allied World will generally have preemptive rights in relation to such Allied World shares or Allied World non-voting shares or rights in proportion to the respective par values of their holdings. In the context of an ordinary capital increase resolved by the general meeting of Allied World shareholders, the shareholders may by a qualified majority of at least 662/3% of the votes and a majority of the par value of the voting shares represented at a general meeting resolve to withdraw or limit the preemptive rights for valid reasons (such as a merger, an acquisition or any of the reasons authorizing the board of directors to withdraw or limit the preemptive rights of shareholders in the context of an authorized capital increase as described below).
 
If the general meeting of shareholders approves the creation of authorized or conditional capital, it can thereby also delegate the decision whether to withdraw or limit the preemptive and advance subscription rights for valid reasons to the board of directors. The Allied World Articles provide for this delegation with respect to Allied World’s authorized and conditional share capital in certain circumstances, including in the case of a merger or acquisition and the other circumstances described below.
 
Rights with Respect to Authorized Share Capital
 
The Allied World board of directors is authorized to withdraw or limit preemptive rights with respect to the issuance of shares from authorized capital if the issuances are made for the purpose of:
 
  •  mergers, acquisitions of enterprises or participations, financing and/or refinancing of such mergers and acquisitions and other investment projects (including by way of private placements);
 
  •  improving the regulatory capital position of Allied World or its subsidiaries (including by way of private placements);
 
  •  broadening the shareholder constituency;
 
  •  the participation of employees; or
 
  •  exchanging Allied World non-voting shares as well as a buy-back of Allied World non-voting shares in exchange for Allied World shares out of authorized share capital.
 
Rights with Respect to Conditional Share Capital
 
In connection with the issuance of bonds, notes or similar instruments convertible into or exercisable or exchangeable for Allied World shares, Allied World shareholders do not have preemptive rights, and the Allied World board of directors is authorized to withdraw or limit the advance subscription rights of shareholders with respect to new bonds, notes or similar instruments if the issuance is for purposes of the financing or


142

refinancing of the acquisition of an enterprise or business or part thereof or new investments planned by Allied World, or for the issuance of convertible bonds and warrants in international capital markets or through a private placement. If the advance subscription rights are withdrawn or limited:
 
  •  the instruments have to be placed at market conditions;
 
  •  the exercise period is not to exceed ten years from the date of issue for warrants and twenty years for conversion rights; and
 
  •  the conversion or exercise price for the new shares is to be set at least in line with the market conditions prevailing at the date on which the instruments are issued. Preemptive rights are excluded with respect to the conditional share capital created for a shareholder warrant previously granted to AIG at the time of Allied World’s formation.
 
The preemptive rights of shareholders are excluded with respect to issuances of new registered shares out of conditional share capital under an equity-based incentive plan to directors, employees, contractors or other persons providing services to Allied World or one of its subsidiaries or affiliates.
 
Participation Certificates
 
The Allied World Articles provide for participation capital amounting to CHF 3,035,100 or 202,340 Allied World non-voting shares.
 
The Allied World non-voting shares have the same entitlement to dividends and liquidation distributions as the voting shares of Allied World. The Allied World Articles further provide that if the share capital and the participation capital are increased at the same time and in the same proportion, shareholders may subscribe only to Allied World shares and participants only to Allied World non-voting shares. The Swiss Code states that if only the participation capital or only the share capital is increased or if one is increased more than the other, preemptive rights are to be allocated in such a way that both shareholders and participants maintain their participation in the same proportion as before. Preemptive rights of the participants (be it on Allied World non-voting shares or Allied World shares) can be limited or withdrawn in accordance with the same criteria and conditions as are applicable to the voting shares.
 
Holders of Allied World non-voting shares are not entitled to attend or vote at the general meeting and may not exercise the shareholder rights associated therewith (e.g., right to request the convocation of a shareholders meeting, right to speak and/or make a motion at the shareholders meeting). As a matter of Swiss law, however, holders of Allied World non-voting shares have the following rights:
 
  •  right to orientation on the invitation to shareholders meetings;
 
  •  similar to shareholders, rights to request access or information on corporate matters;
 
  •  right to make a motion to appoint a special commissioner;
 
  •  right to be informed about the resolutions of the shareholders meetings; and
 
  •  right to initiate certain legal proceedings (e.g., challenge of shareholders resolutions and (limited rights under Swiss law) board resolutions, dissolution of the company, appointment of special commissioner and directors’ liability law suits).
 
The Allied World Articles provide that upon resolution of the general meeting and with the approval of the holders of Allied World non-voting shares, all or any portion of such holders’ Allied World non-voting shares may be converted into Allied World shares, at any time.
 
Some holders of Allied World non-voting shares may also hold a put right that enables them to require Allied World to issue voting shares of Allied World (to them or their third party designees) on a one-for-one basis in exchange for their Allied World non-voting shares. Allied World holds treasury shares for this purpose.

According to the Swiss Code, resolutions limiting the rights of the holders of Allied World non-voting shares afforded by law or the Allied World Articles require an affirmative resolution by an extraordinary general meeting of holders of Allied World non-voting shares.
 
New Shares
 
The new Allied World shares to be issued as merger consideration will be issued by way of an ordinary capital increase to be approved at the Allied World Special Shareholder Meeting. With respect to such issuance of Allied World shares, the pre-emptive rights of the existing shareholders will have to be excluded by resolution at the Allied World Special Shareholder Meeting. The contributions for the new registered shares will be paid by converting existing reserves (Kapitalreserven) into share capital.
 
The new Allied World shares to be issued as merger consideration will be issued, after the approval of the shareholders of Allied World have been obtained as contemplated in this joint proxy statement/prospectus, according to the resolution of the Allied World board of directors implementing the share capital increase in one multiple share document (Globalurkunde). This multiple share document will be deposited with a depository (Verwahrungsstelle), which will log in the Allied World shares reflected by the multiple share document to one or several securities accounts and thus create shares in book-entry form (Bucheffekten).
 
Antitakeover Provisions
 
The Allied World Articles have provisions that could have an anti-takeover effect. These provisions are intended to enhance the likelihood of continuity and stability in the composition of the Allied World board of directors and in the policies formulated by the Allied World board of directors, and may have the effect of discouraging actual or threatened changes of control by limiting certain actions that may be taken by a potential acquiror prior to its having obtained sufficient control to adopt a special resolution amending the Allied World Articles.
 
The Allied World Articles provide that the Allied World board of directors is divided into three classes serving staggered three-year terms. Under the Swiss Code, directors may at any time, with or without cause, be removed from office by resolution of the shareholders at a general meeting of shareholders, provided that a proposal for such resolution has been put on the agenda for the meeting in accordance with the requirements of the Swiss Code and the Allied World Articles. The Allied World Articles provide that a decision of the shareholders at a general meeting to remove a director requires the vote of shareholders holding 662/3% of the voting rights and a majority of the par value of the voting shares, each as represented at a general meeting.
 
The Allied World Articles include an authorized share capital, according to which the board of directors is authorized, at any time during a maximum two-year period, to issue a number of voting shares up to 20% of the share capital registered in the Swiss Commercial Register and to limit or withdraw the preemptive rights of the existing shareholders in various circumstances.
 
The Allied World Articles include a provision that permits the board of directors to refuse the registration of a shareholder as shareholder with voting rights in the share register if, and to the extent, such shareholder owns or otherwise controls alone or together with others 10% of the total voting rights of Allied World share capital as registered with the Swiss Commercial Register or if such shareholder refuses to confirm to the company that it has acquired the voting shares for its own account and benefit.
 
In addition, pursuant to the Allied World Articles, shareholders whose “controlled shares” (as defined in the Allied World Articles) represent 10% or more of the total voting shares of Allied World are limited to voting one vote less than 10% of the total voting rights of Allied World’s share capital as registered with the Swiss Commercial Register, which could make it more difficult for a third party to acquire Allied World without the consent of the Allied World board of directors.

Liquidation Rights
 
Under Swiss law, any surplus arising out of liquidation, after the settlement of all claims of all creditors, will be distributed to shareholders in proportion to the paid-up par value of shares held, subject to Swiss withholding tax requirements.
 
No Redemption; Repurchase
 
Allied World shares are not subject to redemption by Allied World. In addition, the Swiss Code limits a corporation’s ability to hold or repurchase its own common shares. Allied World and its subsidiaries may only repurchase shares to the extent that sufficient freely distributable reserves (including contributed surplus) are available, as described under “Dividends and Other Payments to Shareholders.” The aggregate par value of Allied World shares held by Allied World and its subsidiaries may not exceed 10% of share capital registered in the Swiss Commercial Register. Allied World may repurchase common shares beyond the statutory limit of 10%, however, if shareholders pass a resolution at a general shareholders’ meeting authorizing the Allied World board of directors to repurchase common shares in an amount in excess of 10% and the repurchased shares are dedicated for cancellation. Any common shares repurchased pursuant to such an authorization will then be cancelled at the next general shareholders’ meeting upon the approval of shareholders holding a majority of the common shares represented at the general meeting. Repurchased common shares held by Allied World or its subsidiaries do not carry any rights to vote at a general shareholders’ meeting but are entitled to the economic benefits generally associated with the shares.
 
Stock Exchange Listing
 
Allied World shares are traded on the New York Stock Exchange under the symbol “AWH.”
 
No Sinking Fund
 
The Allied World shares have no sinking fund provisions.
 
Transfer; Transfer Agent
 
Allied World has not imposed any restrictions applicable to the transfer of Allied World shares. The transfer agent for the Allied World shares is Continental Stock Transfer & Trust Company.

COMPARISON OF RIGHTS OF TRANSALLIED SHAREHOLDERS AND
TRANSATLANTIC STOCKHOLDERS
 
The rights of Allied World shareholders are currently governed by the Swiss Code, the Allied World Articles and the organizational regulations of Allied World. The rights of Transatlantic stockholders are currently governed by the DGCL, the Transatlantic charter, and the Transatlantic bylaws. Pursuant to the terms of the merger agreement, Transatlantic stockholders will be entitled to receive Allied World shares and, upon completion of the merger, their rights will be governed by the Swiss Code and the TransAllied Articles and TransAllied organizational regulations, once adopted.
 
This section of the joint proxy statement/prospectus describes the material differences between the rights of TransAllied shareholders and Transatlantic stockholders.
 
This section does not include a complete description of all differences among the rights of TransAllied shareholders and Transatlantic stockholders, nor does it include a complete description of the specific rights of these shareholders. Furthermore, the identification of some of the differences in the rights of these shareholders as material is not intended to indicate that other differences do not exist.
 
You are urged to read carefully the relevant provisions of the Swiss Code and the DGCL, as well as the TransAllied Articles and the TransAllied organizational regulations and the Transatlantic charter and Transatlantic bylaws. You are also urged to read the section entitled “The Merger — Board of Directors and Management Following the Merger,” which describes certain items regarding the board of directors and management of TransAllied that will be reflected in the TransAllied organizational regulations. Copies of the Allied World Articles and organizational regulations and the Transatlantic charter and Transatlantic bylaws are filed as exhibits to the reports of Allied World and Transatlantic incorporated by reference in this joint proxy statement/prospectus.

Voting Rights   Under the TransAllied Articles, each holder of a common share shall be entitled to one vote for each common share registered in his or her name in the TransAllied share register (Aktienregister). Participation certificates are not entitled to any votes. “Controlled Shares” voting rights will be limited, in the aggregate, to a voting power of approximately 10% pursuant to a formula specified in the TransAllied Articles. Controlled Shares are defined generally to include all shares of TransAllied directly, indirectly or constructively owned or beneficially owned by any person or group of persons.   Under the Transatlantic charter, each holder of common stock shall be entitled to one vote for each share of common stock standing in his or her name on the stock transfer books of Transatlantic. Except as otherwise provided in the rights, powers or preferences in any class or series of preferred stock of Transatlantic, all voting rights of Transatlantic shall be vested in the common stock.
         
Supermajority Voting   The Swiss Code and the TransAllied Articles require the affirmative vote of at least two-thirds of the voting rights and a majority of the par value of TransAllied shares, each as represented at a general meeting, to approve the following matters:
 
•     a change in TransAllied’s purpose;
 
•   the creation of shares with privileged voting rights;
 
•   the restriction on transferability of TransAllied shares or TransAllied non-voting shares;

•   the limitation or withdrawal of preemptive rights;
 
•   the alleviating or withdrawal of
  Under the Transatlantic by-laws, the affirmative vote of the holders of a majority of the outstanding shares of Transatlantic stock is all that is required for certain transactions that by applicable law must be submitted to shareholders for their approval, such as, a merger, the sale of substantially all of Transatlantic’s assets, an amendment to the Transatlantic charter or a proposal to dissolve Transatlantic.

•   TransAllied’s liquidation.
 
The same supermajority voting requirements apply to resolutions in relation to transactions among corporations based on the Merger Act, including a merger, demerger or conversion of a corporation, other than a cash-out or certain squeeze-out mergers (in which minority shareholders of the company being acquired may be compensated in a form other than through shares of the acquiring company) where an affirmative vote of 90% of the outstanding common shares is required. Swiss Law also may impose this supermajority voting requirement in connection with the sale of “all or substantially all of its assets.”
   
         
Number of Directors   The TransAllied Articles provide that the TransAllied board shall consist of no less than three and no more than thirteen members. The shareholders have an exclusive right to change the size of the TransAllied board by amending the Articles of Association. TransAllied will have 11 directors initially.   The Transatlantic bylaws provide that the number of directors will not be less than three nor more than twelve, which number may be fixed from time to time by the Transatlantic board of directors. Under the Transatlantic charter, only the Transatlantic board of directors may change the size of


148


Table of Contents

         
   
TransAllied Group Holdings, AG
 
Transatlantic
 
         
      the Transatlantic board of directors. The size of Transatlantic’s board is currently fixed at seven directors and there are currently seven directors serving on the Transatlantic board of directors.
         
Classification of Directors   Under the TransAllied Articles, TransAllied the board of directors is divided into three classes of directors, Class I, Class II and Class III, each of approximately equal size. Each year the TransAllied board shall be renewed by rotation, to the extent possible in equal numbers and in such manner that, after a period of three years, all members will have been subject to re-election. The TransAllied board shall establish the order of rotation, whereas the first term of some members may be less than three years.   The Transatlantic board of directors is not divided into classes. Each director is elected at the annual meeting of stockholders, to hold office until the next annual meeting and until his or her respective successor is duly elected and qualified or until his or her prior death, resignation or removal.
         
Election of Directors   Under the TransAllied Articles, a vote of a simple majority of the votes cast at a general meeting of the shareholders, is required to elect the directors to succeed those whose terms expire (whereby abstentions, broker non- votes, blank or invalid ballots shall be disregarded for purposes of establishing the majority).   Under the Transatlantic bylaws, each director shall be elected by the vote of the majority of the votes cast with respect to the nominee at any meeting at which directors are to be elected at which a quorum is present; provided, however, that the directors shall be elected by a plurality of votes cast on an election that is contested. An election is deemed to be contested if as of a date that is 14 days in advance of the filing date of Transatlantic’s proxy statement for the relevant meeting with the SEC, the number of nominees exceeds the number of directors to be elected.
         
      For purposes of the foregoing, a majority of votes cast means that the number of shares voted “for” a nominee must exceed the votes cast “against” such nominee.
         
Vacancies on the Board of Directors   Under the Swiss Code, a shareholder vote is required to fill   Under the Transatlantic bylaws, if the office of any director becomes

    vacancies on the TransAllied board.   vacant, by reason of death, resignation or removal, the directors remaining in office, although less than a quorum, may fill the vacancy by the affirmative vote of a majority of such remaining directors.
         
      A Transatlantic director elected to fill a vacancy shall serve for the unexpired term of his predecessor in office. Any directorship filled by reason of an increase in the number of directors may be filled by election at a regular meeting or a special meeting of the Transatlantic board of directors or stockholders of Transatlantic, called for that purpose.
         
Removal of Directors   Under the Swiss Code and the TransAllied Articles, only the shareholders may remove a director, and they may do so with or without cause by the affirmative vote of at least 662/3% of the voting rights and a majority of the par value of TransAllied shares, at a shareholders’ meeting where such removal was properly set on the agenda.   Under the Transatlantic charter, a director may be removed from office with or without cause, and only by the affirmative vote of the holders of a majority of the voting power of all of the outstanding capital stock of Transatlantic entitled to vote in respect thereof.
         
Amendment of Charter Documents   Under the Swiss Code and the TransAllied Articles, only the shareholders, acting at the general shareholders’ meeting, have the power to amend the TransAllied Articles. A resolution of the general shareholders’ meeting passed by at least 662/3% of the represented share votes and the majority of the represented shares par value is required to amend those sections of the TransAllied Articles pertaining to the share register, matters requiring a supermajority vote, the voting rights of shares, matters relating to resolutions of the shareholders, restrictions on transferability and shareholder proxies. To amend other sections requires passage of a   Under the Transatlantic charter, Transatlantic has reserved the right to amend the Transatlantic charter. However, the DGCL provides that any amendment to the certificate of incorporation of a Delaware corporation shall be approved by the Transatlantic board of directors, by an affirmative vote of a majority of the outstanding stock entitled to vote thereon, and a majority of the outstanding stock of each class entitled to vote thereon as a class.
 
As permitted by the Transatlantic charter, the Transatlantic board of directors may determine the preferences, limitations, and relative rights of preferred stock

Amendment to Organizational Regulations or Bylaws   Under the TransAllied Articles, the TransAllied board may amend, by majority vote, the organizational regulations at any time without the approval of the shareholders. Under Swiss law, shareholders may not pass or amend organizational regulations but may pass resolutions amending the TransAllied Articles to effectively supersede certain provisions in the TransAllied organizational resolutions, provided that this does not violate the separation of responsibilities.   Under the Transatlantic charter, the Transatlantic board of directors may amend the Transatlantic bylaws without the approval of the stockholders of Transatlantic in any manner that is not inconsistent with the DGCL or the Transatlantic charter. In addition, under the Transatlantic bylaws, either of the board of directors, by majority vote, or the stockholders, by the affirmative vote of holders of record of at least a majority of the combined voting power of all of the outstanding capital stock entitled to vote thereon, may amend or repeal the bylaws of Transatlantic.
         
Extraordinary Shareholder Meetings   Under the TransAllied Articles, extraordinary general shareholders’ meetings may be called by resolution of the shareholders at a general shareholders’ meeting, the auditors or the TransAllied board, or by shareholders with voting power representing at least 10% of the share capital.   Under the Transatlantic bylaws, a special meeting of stockholders for any purpose or purposes may be called by (i) the Transatlantic board of directors, the chairman of the board of directors, the lead director (as appointed under the Transatlantic bylaws), the president or a committee of the Transatlantic board of directors given such power or (ii) the secretary of Transatlantic, upon the request in writing of stockholders holding of record at least 25% of the voting power of the outstanding shares of capital stock of Transatlantic entitled to vote at such meeting.
         
Nomination of Directors and Shareholder Proposals   Under the Swiss Code, nominations of persons for election to the TransAllied board may be made at any time prior to, or at, the general shareholders’ meeting, provided that the election of   Under the Transatlantic bylaws, for nominations of directors and other proposals properly brought before an annual meeting of stockholders by a stockholder, timely notice must be given.

    directors is a matter that has been included in the agenda.
 
Pursuant to the Swiss Code, any shareholder or group of shareholders holding voting shares representing either an aggregate par value of CHF 1 million or 10% of the share capital registered in the commercial register may request that an item be included on the agenda for the general meeting. Under the TransAllied Articles, such request must be in writing and submitted to the chairman up to 60 days before the date of the meeting. Once included on the agenda, under the Swiss Code, no prior notice is required to bring motions related to that item.
  notice must be received by Transatlantic’s secretary at the principal office of Transatlantic not later than the close of business on the 90th day nor earlier than the close of business on the 60th day prior to the first anniversary of the preceding year’s annual meeting or in the case of the special meeting, not later than the close of the 10th business day following the day on which notice of the special meeting was mailed or public announcement thereof was made, whichever occurs first.
         
Limitation of Liability of Directors   Under the Swiss Code, a limitation of directors’ liability is not possible. However, the general meeting of shareholders may pass a resolution discharging the directors from certain limited actions under certain conditions. Consequently, TransAllied’s Articles and the TransAllied organizational regulations contain no provisions limiting the personal liability of directors.   The DGCL permits the adoption of a provision in the certificate of incorporation limiting or eliminating the monetary liability of a director to the corporation or its stockholders by reason of a director’s breach of the fiduciary duty of care.
 
However, the law does not permit any limitation of the liability of a director for:
 
•     breaching the duty of loyalty to the corporation or its stockholders;
 
•   failing to act in good faith;
 
•   obtaining an improper personal benefit from the corporation; or
 
•   paying a dividend or approving a stock repurchase that was illegal under Delaware law.
 
Under the Transatlantic charter, to the fullest extent permitted by Delaware law, a director of Transatlantic shall not be liable to Transatlantic or its stockholders for monetary damages for breach of fiduciary duty as a director. However, if the DGCL is amended


152


Table of Contents

         
   
TransAllied Group Holdings, AG
 
Transatlantic
 
         
      so that it eliminates or further limits the personal liability of directors, then liability of a director of Transatlantic with respect to actions taken prior to such DGCL amendment shall be eliminated or limited to the fullest extent provided by the DGCL, as so amended.
         
Indemnification of Directors and Officers   The TransAllied Articles provide that TransAllied shall indemnify and hold harmless, to the fullest extent permitted by law, each of the members of the TransAllied board and officers out of the assets of TransAllied from and against all actions, costs, charges, losses, damages and expenses which they or any of them may incur or sustain by or by reason of any act done, concurred in or omitted in or about the execution of their duty, or supposed duty on behalf of TransAllied; provided that this indemnity shall not extend to any matter in which any of said persons is found, in a final judgment or decree not subject to appeal, to have committed with intent or gross negligence.
 
Additionally, TransAllied shall advance court costs and attorney’s fees to the members of the board of directors and officers, except in cases where TransAllied itself is plaintiff. TransAllied may however recover such advanced cost if a court or another competent authority holds that the member of the TransAllied board or the officer in question has breached its duties to TransAllied.
  Under the Transatlantic bylaws, Transatlantic shall indemnify, to the full extent of the law, any person made or threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding by reason of the fact that such person is or was a director or officer of Transatlantic or serves or served at the request of Transatlantic as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, or other enterprise, including service with respect to an employee benefit plan, against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such a proceeding, if he or she acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of Transatlantic, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.
 
Such rights shall be contract rights and shall include the right to be paid by Transatlantic expenses incurred in defending any action, suit or proceeding in advance of its final disposition, provided that such person shall repay all amounts advanced if it is ultimately determined that such person is not entitled to

      indemnification under the Transatlantic bylaws.
         
Preemptive Rights   Under the Swiss Code, TransAllied shareholders are generally entitled to preemptive rights in relation to new shares or rights in proportion to the par value that the new shares bear to the par value of shares outstanding before a new issuance. These preemptive rights, however, are limited under the Swiss Code and the TransAllied Articles. Under the TransAllied Articles, shareholders with the affirmative vote of shareholders holding 662/3% of the voting rights and a majority of the par value of the shares, each as represented at the general shareholders’ meeting, may withdraw or limit the preemptive rights for valid reasons, such as a merger or acquisition. In addition, a general shareholders’ meeting that approves the creation of authorized or conditional share capital thereby may delegate the decision whether to withdraw or limit the preemptive or advance subscription rights for valid reasons to the TransAllied board.   Under the Transatlantic charter, the holders of common stock and preferred stock are not entitled to preemptive or other similar subscription rights to purchase any of Transatlantic’s securities.
         
Dividends   Under the Swiss Code and the TransAllied Articles, TransAllied shareholders are entitled to receive, from funds legally available for the payment thereof, pro rata dividends as and when declared. Under Swiss law, dividends may be paid out only if a corporation has sufficient distributable profits from previous fiscal years or if a corporation has freely distributable reserves, which may include contributed surplus.   Under the Transatlantic bylaws, subject to the express terms of any outstanding series of preferred stock, the Transatlantic board of directors may, out of funds legally available therefor at any regular or special meeting, declare dividends upon the capital stock of Transatlantic as and when they deem expedient.
         
   
 
Under the Swiss Code and the TransAllied Articles, the board of directors may propose to shareholders that a dividend be paid but cannot itself authorize the dividend. The affirmative vote of
   


154


Table of Contents

         
   
TransAllied Group Holdings, AG
 
Transatlantic
 
         
    shareholders holding a majority of shares represented at a general meeting must approve distributions of dividends.    
         
   
 
Under Swiss law, dividend payments out of earnings and similar payments are subject to Swiss withholding tax. Dividend payments in the form of a return of capital by reducing the par value are not subject to Swiss withholding tax. Until at least TransAllied’s Annual Shareholder Meeting in 2012, TransAllied intends to make further payments to shareholders in the form of reductions to registered share capital.
   
         
Mergers and Consolidations, Generally   Business combinations and other such transactions that are binding on all shareholders of TransAllied are governed by the Merger Act. As described above under “Supermajority Voting,” a statutory merger or demerger requires that at least 662/3% of the shares and a majority of the par value of the shares, each as represented at the general shareholders’ meeting, vote in favor of the transaction.   Under the DGCL, the vote of the holders of a majority of the outstanding shares of Transatlantic common stock is required to approve a business combination, unless the Transatlantic board of directors conditions the submission of the business combination on receipt of a greater vote.
         
Restrictions on Business Combinations with Interested Shareholders   Under the Swiss Code, there generally is no prohibition of business combinations with interested shareholders. However, the TransAllied Articles provides that no individual or legal entity may, directly or through Constructive Ownership (as defined in Article 14 of the TransAllied Articles) or otherwise control voting rights with respect to 10% or more of the registered share capital recorded in the Swiss Commercial Register, unless otherwise approved by the TransAllied board.   The DGCL prohibits a Delaware corporation from engaging in a “business combination” with an “interested stockholder” owning 15% or more of the corporation’s voting stock for three years following the time that the “interested stockholder” becomes such, subject to certain exceptions. Transatlantic has not opted out of Section 203 in the Transatlantic charter and is therefore governed by the terms of this provision of the DGCL.

Appraisal rights are not available under Delaware law to stockholders of the surviving corporation when a corporation is to be the surviving corporation and no vote of its stockholders is required to approve the merger in accordance with Section 251(f) of the DGCL. In addition, no appraisal rights are available under Delaware law to holders of shares of any class of or series of stock which is either:
         
     
 
•     listed on a national securities exchange; or
 
•   held of record by more than 2,000 stockholders.
 
Notwithstanding the above, appraisal rights shall be available to those stockholders who are required by the terms of the agreement of merger or consolidation to accept for that stock anything other than:
 
•   shares of stock of the corporation surviving or resulting from the merger or consolidation, or depository receipts in respect thereof;
 
•   shares of stock of another corporation, or depository receipts in respect thereof, which, as of the effective date of the merger or consolidation, are listed on a national securities exchange or held of record by more than 2,000 stockholders;

stockholders. As permitted by the Exchange Act, only one copy of this joint proxy statement/prospectus is being delivered to stockholders residing at the same address, unless stockholders have notified the company whose shares they hold of their desire to receive multiple copies of the joint proxy statement/prospectus. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies.
 
If, at any time, you no longer wish to participate in householding and would prefer to receive a separate joint proxy statement/prospectus, or if you are receiving multiple copies of this joint proxy statement/prospectus and wish to receive only one, please contact the company whose shares you hold at their address identified in the preceding paragraph. Each of Transatlantic and Allied World will promptly deliver, upon oral or written request, a separate copy of this joint proxy statement/prospectus to any shareholder residing at an address to which only one copy was mailed. Requests for additional copies should be directed to: Allied World Assurance Company Holdings, AG, Attention: Corporate Secretary, Lindenstrasse 8, 6340 Baar, Zug, Switzerland, 441-278-5400 or to Transatlantic Holdings, Inc.

As of the date of this joint proxy statement/prospectus, neither the Allied World board of directors nor the Transatlantic board of directors knows of any matters that will be presented for consideration at either the Allied World Special Shareholder Meeting or the Transatlantic Special Shareholder Meeting other than as described in this joint proxy statement/prospectus. If any other matters come before either the Allied World Special Shareholder Meeting or the Transatlantic Special Shareholder Meeting or any adjournment or postponement thereof and shall be voted upon, the proposed proxy will be deemed to confer authority to the individuals named as authorized therein to vote the shares represented by the proxy as to any matters that fall within the purposes set forth in the notice of Special Shareholder Meeting. It is intended that the persons named in the enclosed proxy and acting thereunder will vote in accordance with their best judgment on such matters.

(i) Limited Liability Company Interest of Merger Sub.  The sole limited liability company interest of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be converted into one hundred (100) fully paid and nonassessable shares of common stock, par value $0.01 per share, of the Surviving Corporation.

0.88 (the ratio of such number to 1, the “Exchange Ratio”) validly issued, fully paid and nonassessable registered ordinary shares, par value CHF 15.00 per share (as may be adjusted in connection with the payment of dividends by virtue of a par value reduction, as approved by Allied World’s shareholders at its 2011 annual general meeting), of Allied World (the “Allied World Shares” and, such Allied World Shares into which shares of Transatlantic Common Stock are converted pursuant to this Section 2.1(a)(iii), together with any cash paid in lieu of fractional shares pursuant to Section 2.2(e), the “Merger Consideration”). All shares of Transatlantic Common Stock converted pursuant to this Section 2.1(a)(iii), when so converted, shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate that, immediately prior to the Effective Time, represented any such shares of Transatlantic Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration and any dividends or other distributions to which holders become entitled upon the surrender of such shares of Transatlantic Common Stock in accordance with Section 2.2(c), without interest.

2.2   Exchange of Certificates.
 
(a) Exchange Agent.  Prior to the Effective Time, Allied World and Transatlantic shall appoint a commercial bank or trust company to be mutually agreed upon to act as exchange agent (the “Exchange Agent”) for the purpose of exchanging (i) certificates that immediately prior to the Effective Time evidenced shares of Transatlantic Common Stock (“Certificates”) or (ii) uncertificated shares of Transatlantic Common Stock represented by book-entry (“Book-Entry Shares”), in each case, for the applicable Merger Consideration pursuant to an exchange agent agreement. Allied World shall deposit, or shall cause to be deposited, with the Exchange Agent at or prior to the Effective Time, (x) evidence of Allied World Shares in book-entry form issuable pursuant to Section 2.1 (and/or certificates representing such shares, at Allied World’s election), and (y) cash sufficient for payment in lieu of fractional Allied World Shares pursuant to Section 2.2(e). Allied World shall make available from time to time after the Effective Time as necessary, cash in an amount sufficient to pay any dividends or distributions to which holders of shares of Transatlantic Common Stock may be entitled pursuant to Section 2.2(c). All such Allied World Shares and cash deposited with the Exchange Agent pursuant to this Section 2.2(a) is hereinafter referred to as the “Exchange Fund.”
 
(b) Exchange Procedures.  As soon as reasonably practicable after the Effective Time, Allied World shall cause the Exchange Agent to mail to each holder of Certificates or Book-Entry Shares whose shares were converted pursuant to Section 2.1(a)(iii) into the right to receive the Merger Consideration (A) a letter of transmittal for use in such exchange (which shall be in form and substance reasonably satisfactory to Allied World and Transatlantic and shall specify that the delivery shall be effected, and risk of loss and title in respect of the Certificates or Book-Entry Shares shall pass, only upon proper delivery of the Certificates to the Exchange Agent or, in the case of Book-Entry Shares, upon adherence to the procedures set forth in the letter of transmittal) and (B) instructions to effect the surrender of the Certificates or Book-Entry Shares in exchange for the applicable Merger Consideration and any dividends or other distributions payable in respect thereof pursuant to Section 2.2(c). Upon proper surrender of a Certificate or Book-Entry Share to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor (x) Allied World Shares representing that number of whole Allied World Shares that such holder has the right to receive in respect of the aggregate number of shares of Transatlantic Common Stock previously represented by such Certificate or Book-Entry Share pursuant to Section 2.1 and (y) a check representing cash in lieu of fractional


A-4


Table of Contents

shares that the holder has the right to receive pursuant to Section 2.2(e) and in respect of any dividends or other distributions that the holder has the right to receive pursuant to Section 2.2(c). Until surrendered as contemplated by this Section 2.2, each Certificate and Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive, upon such surrender, the Merger Consideration that the holder of such Certificate or Book-Entry Share has the right to receive in respect thereof pursuant to Section 2.1 (and cash in respect of any dividends or other distributions pursuant to Section 2.2(c)). No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate or Book-Entry Share.
 
(c) Treatment of Unexchanged Shares.  No dividends or other distributions declared or made with respect to Allied World Shares with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate or Book-Entry Share with respect to the Allied World Shares deliverable upon surrender thereof, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.2(e), until the surrender of such Certificate or Book-Entry Share in accordance with this Article II. Subject to escheat or other applicable Law, following surrender of any such Certificate or Book-Entry Share, there shall be paid to the holder thereof, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional Allied World Share that such holder has the right to receive pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such number of whole Allied World Shares that such holder has the right to receive pursuant to Section 2.1(a)(iii) and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such number of whole Allied World Shares that such holder has the right to receive pursuant to Section 2.1(a)(iii).
 
(d) No Further Ownership Rights in Transatlantic Common Stock.  The Allied World Shares delivered and cash paid in accordance with the terms of this Article II upon conversion of any shares of Transatlantic Common Stock shall be deemed to have been delivered and paid in full satisfaction of all rights pertaining to such shares of Transatlantic Common Stock. From and after the Effective Time, (i) all holders of Certificates and Book-Entry Shares shall cease to have any rights as stockholders of Transatlantic other than the right to receive the Merger Consideration and any dividends or other distributions that holders have the right to receive upon the surrender of such Certificate or Book-Entry Share in accordance with Section 2.2(c), without interest, and (ii) the stock transfer books of Transatlantic shall be closed with respect to all shares of Transatlantic Common Stock outstanding immediately prior to the Effective Time. From and after the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Transatlantic Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates or Book-Entry Shares formerly representing shares of Transatlantic Common Stock are presented to the Surviving Corporation, Allied World or the Exchange Agent for any reason, such Certificates or Book-Entry Shares shall be canceled and exchanged as provided in this Article II.
 
(e) No Fractional Shares.  No fractional Allied World Shares shall be issued in connection with the Merger, no certificates or scrip representing fractional Allied World Shares shall be delivered upon the conversion of Transatlantic Common Stock pursuant to Section 2.1, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a holder of Allied World Shares. Notwithstanding any other provision of this Agreement, each holder of shares of Transatlantic Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of an Allied World Share (after aggregating all shares represented by the Certificates and Book-Entry Shares delivered by such holder) shall receive, in lieu thereof and upon surrender thereof, cash (without interest) in an amount equal to such fractional amount multiplied by the last reported sale price of Allied World Shares on the New York Stock Exchange (the “NYSE”) (as reported in The Wall Street Journal (Northeast edition) or, if not reported therein, in another authoritative source mutually selected by Allied World and Transatlantic) on the first trading day immediately following the date on which the Effective Time occurs.
 
(f) Termination of Exchange Fund.  Any portion of the Exchange Fund (including any interest or other amounts received with respect thereto) that remains unclaimed by, or otherwise undistributed to, the holders of Certificates and Book-Entry Shares for 180 days after the Effective Time shall be delivered to Allied World, upon demand, and any holder of Certificates or Book-Entry Shares who has not theretofore complied with this


A-5


Table of Contents

Article II shall thereafter look only to Allied World for satisfaction of its claim for Merger Consideration and any dividends and distributions which such holder has the right to receive pursuant to this Article II.
 
(g) No Liability.  None of Allied World, Transatlantic, Merger Sub or the Exchange Agent shall be liable to any Person in respect of any portion of the Exchange Fund or the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Notwithstanding any other provision of this Agreement, any portion of the Merger Consideration or the cash to be paid in accordance with this Article II that remains undistributed to the holders of Certificates and Book-Entry Shares as of the second anniversary of the Effective Time (or immediately prior to such earlier date on which the Merger Consideration or such cash would otherwise escheat to or become the property of any Governmental Entity), shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.
 
(h) Investment of Exchange Fund.  The Exchange Agent shall invest any cash in the Exchange Fund as directed by Allied World on a daily basis, provided that, subject to Section 2.2(g), no such investment or losses will affect the cash payable to holders of Certificates or Book-Entry Shares. Any interest or other amounts received with respect to such investments shall be paid to Allied World.
 
(i) Withholding Rights.  Each of Allied World and the Exchange Agent (without duplication) shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of a Certificate or Book-Entry Share pursuant to this Agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under applicable Tax Law. Any amounts so deducted, withheld and paid over to the appropriate Taxing Authority shall be treated for all purposes of this Agreement as having been paid to the holder of the Certificate or Book-Entry Share in respect of which such deduction or withholding was made.
 
(j) Lost Certificates.  If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Allied World or the Exchange Agent, the posting by such Person of a bond in such amount as Allied World or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Exchange Agent (or, if subsequent to the termination of the Exchange Fund and subject to Section 2.2(g), Allied World) shall deliver, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration and any dividends and distributions deliverable in respect thereof pursuant to this Agreement.
 
2.3  Transatlantic Stock Options and Other Equity Awards.
 
(a) Prior to the Effective Time, the Board of Directors of Transatlantic (the “Transatlantic Board”) (or, if appropriate, the committee thereof administering the Transatlantic Stock Plans) shall adopt such resolutions or take such other actions as may be required to effect the following:
 
(i) adjust the terms of all outstanding Transatlantic Stock Options to provide that, at the Effective Time, each Transatlantic Stock Option outstanding immediately prior to the Effective Time, whether vested or unvested, shall be deemed to constitute an option to acquire, on the same terms and conditions as were applicable under such Transatlantic Stock Option (including any vesting or forfeiture provisions or repurchase rights, but taking into account any acceleration thereof provided for in the relevant Transatlantic Stock Plan or in the related award document by reason of the transactions contemplated hereby), a number of Allied World Shares (rounded down to the nearest whole share) equal to the product of (x) the number of shares of Transatlantic Common Stock subject to such Transatlantic Stock Option multiplied by (y) the Exchange Ratio, at an exercise price per Allied World Share (rounded up to the nearest whole cent) equal to the quotient of (x) the exercise price per share of Transatlantic Common Stock subject to such Transatlantic Stock Option divided by (y) the Exchange Ratio (each, a “Transatlantic Rollover Option”); provided, however, that in the case of any option to which Section 421 of the Internal Revenue Code of 1986, as amended (the “Code”), applies by reason of its qualification under either Section 422 or 424 of the Code, the option price, the number of shares purchasable pursuant to such option and the terms and conditions of exercise of such option shall be determined in order to

comply with Section 424(a) of the Code and such adjustment shall in all events comply with the requirements of Section 409A of the Code;
 
(ii) adjust the terms of all outstanding Transatlantic Stock-Based Awards (other than Transatlantic Stock Options) to provide that, at the Effective Time, such Transatlantic Stock-Based Awards outstanding immediately prior to the Effective Time shall be converted into Allied World Shares or other compensatory awards denominated in Allied World Shares subject to a risk of forfeiture to, or right of repurchase by, Allied World (each, a “Converted Transatlantic Stock-Based Award”), with the same terms and conditions as were applicable under such Transatlantic Stock-Based Awards (including any vesting or forfeiture provisions or repurchase rights, but taking into account any acceleration thereof provided for in the relevant Transatlantic Stock Plan or in the related award document by reason of the transactions contemplated hereby), and each holder of Transatlantic Stock-Based Awards shall be entitled to receive a number of Converted Transatlantic Stock-Based Awards equal to the product of (x) the number of Transatlantic Stock-Based Awards held by such holder immediately prior to the Effective Time and (y) the Exchange Ratio;
 
(iii) adjust the performance goals for, or convert, all Converted Transatlantic Stock-Based Awards that vest based on the achievement of performance criteria in the manner agreed to by Transatlantic and Allied World within 15 Business Days following the date hereof (or such later time as may be agreed to by the parties) to appropriately reflect the Merger with respect to performance periods that have not ended prior to the Effective Time;
 
(iv) make such other changes to the Transatlantic Stock Plans as it deems appropriate to give effect to the Merger (subject to the approval of Allied World, which shall not be unreasonably withheld, conditioned or delayed); and
 
(v) ensure that, after the Effective Time, no Transatlantic Stock Options or Transatlantic Stock-Based Awards may be granted under any Transatlantic Stock Plans and that from and after the Effective Time awards under the Transatlantic Stock Plans shall be granted with respect to Allied World Shares.

As soon as practicable after the Effective Time, Allied World shall deliver to the holders of outstanding Transatlantic Stock Options and Transatlantic Stock-Based Awards notices explaining the adjustments being made to such Transatlantic Stock Options and Transatlantic Stock-Based Awards in connection with the transactions contemplated by this Section 2.3, and the agreements evidencing the grants of such Transatlantic Stock Options and Transatlantic Stock-Based Awards shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 2.3 after giving effect to the Merger).
 
(c) Allied World shall take all corporate action necessary to reserve for issuance a sufficient number of Allied World Shares for delivery upon exercise of the Transatlantic Rollover Options and Converted Transatlantic Stock-Based Awards assumed in accordance with this Section 2.3. As soon as reasonably practicable after the Effective Time, Allied World shall file a registration statement on Form S-8 (or any successor or other appropriate form) with respect to the Allied World Shares subject to such Transatlantic Rollover Options and Converted Transatlantic Stock-Based Awards and shall use its reasonable best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as Allied World is subject to the reporting requirements pursuant to Section 13 or 15(d) of the Exchange Act and such Transatlantic Rollover Options and Converted Transatlantic Stock-Based Awards remain outstanding.
 
2.4  Further Assurances.  If, at any time before or after the Effective Time, Allied World or Transatlantic reasonably believes or is advised that any further instruments, deeds, assignments or assurances are reasonably necessary or desirable to consummate the Merger or to carry out the purposes and intent of this Agreement at or after the Effective Time, then Allied World, Merger Sub, Transatlantic, the Surviving Corporation and their respective officers and directors shall execute and deliver all such proper instruments,

(c) As used in this Agreement, “Competing Transaction” means, with respect to Allied World or Transatlantic, as the case may be (for this purpose, the “Target Party”), any of (i) a transaction, including any tender offer, exchange offer or share exchange, pursuant to which any third Person (or group) other than the other party to this Agreement (the “Non-Target Party”) or such third Person’s Affiliates, or the stockholders of such third Person, directly or indirectly, acquires or would acquire beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of 10% or more of the outstanding shares of common stock or ordinary shares, as applicable, of the Target Party or of the outstanding voting power of the Target Party (or options, rights or warrants to purchase, or securities convertible into or exchangeable for, such common stock or ordinary shares or other securities representing such voting power), whether from the Target Party or pursuant to a tender offer or exchange offer or otherwise, (ii) a merger, amalgamation, consolidation or business combination pursuant to which any third Person or group of Persons (other than the Non-Target Party or its Affiliates) party thereto, or the stockholders of such third Person or Persons, beneficially owns or would beneficially own 10% or more of the outstanding shares of common stock or ordinary shares, as applicable, or the outstanding voting power of the Target Party, or, if applicable, any surviving entity or the parent entity resulting from any such transaction, immediately upon consummation thereof, (iii) a recapitalization of Target Party or any of its Subsidiaries or any transaction similar to a transaction referred to in clause (ii) involving the Target Party or any of its Subsidiaries pursuant to which any third Person or group of Persons (other than the Non-Target Party or its Affiliates) party thereto, or its stockholders, beneficially owns or would beneficially own 10% or more of the outstanding shares of common stock or ordinary shares, as applicable, or the outstanding voting power of the Target Party or such Subsidiary or, if applicable, the parent entity resulting from any such transaction immediately upon consummation thereof or (iv) any transaction pursuant to which any third Person or group of Persons (other than the Non-Target Party or its Affiliates) directly or indirectly (including by way of merger, consolidation, share exchange, amalgamation, other business combination, partnership, joint venture or otherwise) acquires or would acquire control of assets (including for this purpose the equity securities of, or other ownership interest in, Subsidiaries of the Target Party and securities of the entity surviving any merger or business combination involving any of the Subsidiaries of the Target Party) of the Target Party or any of its Subsidiaries representing 10% or more of consolidated revenues, net income, or EBITDA for the last 12 full calendar months or the fair market value of all the assets of the Target Party and its Subsidiaries, taken as a whole, immediately prior to such transaction; provided, however, that no transaction involving solely the acquisition of capital stock or assets of any Allied World Subsidiary by Allied World, or of any Transatlantic Subsidiary by Transatlantic, will be deemed to be a Competing Transaction. Wherever the term “group” is used in this Agreement, it is used as defined in Rule 13d-3 under the Exchange Act.
 
(d) The Target Party shall notify the Non-Target Party promptly (but in no event later than 24 hours) after receipt of any Acquisition Proposal, or any material modification of or material amendment to any Acquisition Proposal, or any inquiry or request for non-public information relating to the Target Party or any of its Subsidiaries or for access to the properties, books or records of the Target Party or any of its Subsidiaries by any Person that is reasonably likely to lead to or contemplate an Acquisition Proposal. Such notice to the Non-Target Party shall be made orally and in writing and shall indicate the identity of the Person or Persons making the Acquisition Proposal or inquiry or requesting non-public information or access to the properties, books or records of the Target Party or any of its Subsidiaries, and a copy of the Acquisition Proposal or, if not in writing, a written summary in reasonable detail of the material terms of any such Acquisition Proposal, inquiry or request or modification or amendment to an Acquisition Proposal. The Target Party shall (i) keep the Non-Target Party fully informed, on a current basis, of any material changes in the status of, and any material changes or modifications in the terms of, any such Acquisition Proposal, inquiry or request and, if requested by the Non-Target Party, counsel for the Target Party shall consult with counsel for the Non-Target Party once per day, at mutually agreeable times, regarding such status and any such changes or modifications, and (ii) provide to the Non-Target Party as soon as practicable after receipt or delivery thereof with copies of all correspondence and other written material sent or provided to the Target Party from any third party in connection with any Acquisition Proposal or sent or provided by the Target Party to any third

party in connection with any Acquisition Proposal; provided, however, that any material written material or material correspondence shall be sent or provided pursuant to clause (ii) within 24 hours after receipt or delivery thereof. Neither Allied World nor Transatlantic shall enter into any agreement on or after the date hereof that would prevent such party from providing any information required by this Section 5.5 to the other party.
 
(e) Notwithstanding anything to the contrary in this Section 5.5, at any time prior to obtaining the Allied World Requisite Stockholder Vote or the Transatlantic Requisite Stockholder Vote, as applicable, the Target Party may furnish or cause to be furnished information to, and enter or cause to be entered into discussions with, and only with, a Person (and its representatives) who has made a bona fide written Acquisition Proposal that was not solicited on or after the date of this Agreement and that did not otherwise result from a breach of Section 5.5(a) or Section 5.5(b), as applicable, if the Target Party’s Board of Directors (the “Target Board”) has (i) determined in good faith (after consultation with its outside legal counsel and financial advisor or advisors) that (A) such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (B) the failure to enter into discussions regarding the Acquisition Proposal would result in a breach of its fiduciary duties under applicable Law, (ii) provided at least three Business Days’ notice to the Non-Target Party of its intent to furnish information to or enter into discussions with such Person in accordance with this Section 5.5(e), and (iii) obtained from such Person an executed confidentiality agreement containing terms that are determined in good faith by the Target Party to be substantially similar to and not less favorable to the Target Party, in the aggregate, than those contained in the Confidentiality Agreement (it being understood that such confidentiality agreement and any related agreements shall not include any provision calling for any exclusive right to negotiate with such Person or having the effect of prohibiting the Target Party from satisfying its obligations under this Agreement). Unless such information has been previously provided to the Non-Target Party, all information that is provided by the Target Party to the Person making such Acquisition Proposal shall be provided to the Non-Target Party. During the three Business Day period set forth in clause (ii), the Non-Target Party shall have the right to make a presentation to the Target Board.
 
(f) As used in this Agreement, “Superior Proposal” means a bona fide written Acquisition Proposal made by a third Person (or group of Persons) (and not obtained in breach of this Agreement, including, without limitation, this Section 5.5) to consummate a merger, amalgamation, consolidation, business combination or other similar transaction involving the Target Party pursuant to which the stockholders of the Target Party immediately preceding such transaction would hold less than 50% of the outstanding shares of common stock or ordinary shares, as applicable, of, or less than 50% of the outstanding voting power of, the Target Party, any surviving entity or the parent entity resulting from any such transaction immediately upon consummation thereof that the Target Board (after consultation with its outside legal counsel and its financial advisor or advisors) determines in good faith to be more favorable to the Target Party’s stockholders than the Merger, taking into account all relevant factors, including value and other financial considerations, legal and regulatory considerations and any conditions to, and expected timing and risks of, completion, as well as any changes to the terms of the Merger proposed by the Non-Target Party in response to such Superior Proposal.
 
(g) Except as permitted by this Section 5.5(g), neither the Target Board nor any committee thereof shall (i) (A) withdraw (or modify or qualify in any manner adverse to the Non-Target Party) the approval, recommendation or declaration of advisability by the Target Board or any such committee of this Agreement, the Restated Articles and the Merger or any of the other transactions contemplated hereby, (B) adopt, approve, recommend, endorse or otherwise declare advisable the adoption of any Acquisition Proposal or (C) resolve, agree or publicly propose to take any such actions (each such action set forth in this Section 5.5(g)(i) being referred to herein as an “Adverse Recommendation Change”) or (ii) cause or permit the Target Party to enter into, or resolve, agree or propose publicly to do so with respect to, any Allied World Acquisition Agreement (in the case of Allied World) or Transatlantic Acquisition Agreement (in the case of Transatlantic) (other than a confidentiality agreement as referred to in Section 5.5(e)). Notwithstanding anything to the contrary in this Section 5.5, at any time prior to obtaining the Allied World Requisite Stockholder Vote (in the case of Allied World) or the Transatlantic Requisite Stockholder Vote (in the case of Transatlantic) the Target Board may, if the Target Board determines in good faith that the failure to do so would result in a breach of its fiduciary duties under applicable Law, taking into account all adjustments to the terms of this Agreement that may be

offered by the Non-Target Party pursuant to this Section 5.5(g), make an Adverse Recommendation Change; provided, however, that the Target Party may not make an Adverse Recommendation Change, unless (1) the Target Party promptly notifies the Non-Target Party in writing at least three Business Days before taking that action of its intention to do so, and specifying the reasons therefor, including the terms and conditions of, and the identity of any Person making any Acquisition Proposal, and contemporaneously furnishing a copy of any relevant Allied World Acquisition Agreement (in the case of Allied World) or Transatlantic Acquisition Agreement (in the case of Transatlantic) and any other relevant transaction documents (it being understood and agreed that any amendment to the financial terms or any other material term of such Acquisition Proposal shall require a new written notice by the Target Party and a new three Business Day period) and (2) prior to the expiration of such three Business Day period, in the case of an Acquisition Proposal, the Non-Target Party does not make a proposal to adjust the terms and conditions of this Agreement that the Target Board determines in good faith to be at least as favorable as the Acquisition Proposal after giving effect to, among other things, the payment of the Termination Fee set forth in Section 6.6, such that the Target Board determines such action is no longer required by its fiduciary duties to the stockholders of the Target Party under applicable Law. During the three Business Day period prior to its effecting an Adverse Recommendation Change, the Target Party shall, and shall cause its financial and legal advisors to, negotiate with the Non-Target Party in good faith (to the extent the Non-Target Party seeks to negotiate) regarding any revisions to the terms of the transactions contemplated by this Agreement proposed by the Non-Target Party. The Target Party shall not submit to the vote of its stockholders any Acquisition Proposal, or, except as permitted herein, propose to do so.
 
(h) (i) Nothing contained in this Section 5.5 shall prohibit the Target Party or its Subsidiaries from taking and disclosing to its stockholders a position required by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act and (ii) no disclosure that the Allied World Board or the Transatlantic Board may determine (after consultation with counsel) that it or Allied World or Transatlantic, as applicable, is required to make under applicable Law shall constitute a violation of this Agreement; provided, however, that in any event neither the Allied World Board nor the Transatlantic Board shall make an Adverse Recommendation Change except in accordance with Section 5.5(g).  Any disclosure by the Target Party relating to an Acquisition Proposal shall be deemed to be an Adverse Recommendation Change by the Target Party, unless the Target Board reaffirms its recommendation and declaration of advisability with respect to this Agreement in such disclosure.
 
(i) Each of Allied World and Transatlantic and their respective Subsidiaries shall immediately cease and cause to be terminated any existing discussions or negotiations with any Persons (other than the other party to this Agreement) conducted heretofore with respect to any Acquisition Proposal, and shall use reasonable best efforts to cause all Persons, other than the other party hereto, who have been furnished confidential information regarding such party in connection with the solicitation of or discussions regarding an Acquisition Proposal within the twelve (12) months prior to the date of this Agreement promptly to return or destroy such information.
 
(j) It is understood that any violation of the restrictions set forth in this Section 5.5 by any director, officer, employee, controlled Affiliate, agent or representative (including financial or legal advisor or other retained representative) of either party or any of its Subsidiaries or controlled Affiliates shall be deemed to be a breach of this Section 5.5 by such party.

Allied World Assurance Company Holdings, AG
Lindenstrasse 8
6340 Baar
Zug, Switzerland
 
June 12, 2011
 
Lady and Gentlemen:
 
Deutsche Bank Securities Inc. (“Deutsche Bank”) has acted as financial advisor to Allied World Assurance Company Holdings, AG (“Parent”) in connection with the Agreement and Plan of Merger (the “Merger Agreement”), to be entered into among Parent, GO Sub, LLC, a subsidiary of Parent (“Merger Sub”), and Transatlantic Holdings, Inc. (the “Company”), which provides, among other things, for the merger of Merger Sub with and into the Company, as a result of which the Company will become a wholly owned subsidiary of Parent (the “Transaction”). As set forth more fully in the Merger Agreement, as a result of the Transaction, each share of common stock, par value $1.00 per share, of the Company (the “Company Common Stock”) (other than dissenting shares and shares owned directly or indirectly by the Company or Parent) will be converted into the right to receive 0.88 ordinary shares (the “Exchange Ratio”), par value CHF15.00 per share (as may be adjusted in connection with the par value reduction as approved by Parent’s shareholders at Parent’s 2011 annual general meeting) (the “Parent Shares”), of Parent.
 
You have requested our opinion as to the fairness of the Exchange Ratio, from a financial point of view, to Parent.
 
In connection with our role as financial advisor to the Board of Directors of Parent, and in arriving at our opinion, we reviewed certain publicly available financial and other information concerning the Company and Parent, including certain statutory statements filed by the insurance subsidiaries of both the Company and Parent. We also reviewed certain internal analyses, financial forecasts and other information relating to the Company and Parent prepared by management of the Company and Parent, respectively, and certain analyses and financial forecasts relating to the Company prepared by management of Parent. We have also reviewed certain reports regarding the Company’s reserves for losses and loss adjustment expenses prepared for Parent by third party actuaries. We have also held discussions with certain senior officers and other representatives and advisors of the Company and Parent regarding the businesses and prospects of the Company and Parent, respectively, and of Parent after giving effect to the Transaction, including certain cost savings and operating synergies jointly projected by the managements of the Company and Parent to result from the Transaction. In addition, Deutsche Bank has reviewed the reported prices and trading activity for both the Parent Shares and the Company Common Stock, and, (i) to the extent publicly available, compared certain financial and stock market information for Parent and the Company with similar information for certain other companies we considered relevant whose securities are publicly traded, (ii) to the extent publicly available, reviewed the financial terms of certain recent business combinations which we deemed relevant, (iii) reviewed a draft dated June 10, 2011 of the Merger Agreement, and (iv) performed such other studies and analyses and considered such other factors as we deemed appropriate.
 
Deutsche Bank has not assumed responsibility for independent verification of, and has not independently verified, any information, whether publicly available or furnished to it, concerning the Company or Parent, including, without limitation, any financial information considered in connection with the rendering of its opinion. Accordingly, for purposes of its opinion, Deutsche Bank has, with your permission, assumed and relied upon the accuracy and completeness of all such information. Deutsche Bank has not conducted a physical inspection of any of the properties or assets, and has not prepared or obtained any independent evaluation or appraisal of any of the assets or liabilities (including, without limitation, any contingent, derivative or off-balance-sheet assets and liabilities), of the Company or Parent or any of their respective subsidiaries, nor have we evaluated the solvency or fair value of the Company or Parent under any state or


Table of Contents

federal law relating to bankruptcy, insolvency or similar matters. With respect to the financial forecasts, including, without limitation, the analyses and forecasts of the amount and timing of certain cost savings, operating efficiencies, revenue effects, financial synergies and other strategic benefits projected by Parent to be achieved as a result of the Transaction (collectively, the “Synergies”), made available to Deutsche Bank and used in its analyses, Deutsche Bank has assumed with your permission that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of the Company and Parent as to the matters covered thereby. In rendering its opinion, Deutsche Bank expresses no view as to the reasonableness of such forecasts and projections, including, without limitation, the Synergies, or the assumptions on which they are based. Deutsche Bank’s opinion is necessarily based upon economic, market and other conditions as in effect on, and the information made available to it as of, the date hereof. We expressly disclaim any undertaking or obligation to advise any person of any change in any fact or matter affecting our opinion of which we become aware after the date hereof.
 
For purposes of rendering its opinion, Deutsche Bank has assumed with your permission that, in all respects material to its analysis, the Transaction will be consummated in accordance with its terms, without any material waiver, modification or amendment of any term, condition or agreement. Deutsche Bank has also assumed that all material governmental, regulatory, contractual or other approvals and consents required in connection with the consummation of the Transaction will be obtained and that in connection with obtaining any necessary governmental, regulatory, contractual or other approvals and consents, no restrictions, terms or conditions will be imposed that would be material to our analysis. We are not legal, regulatory, tax or accounting experts and have relied on the assessments made by Parent and its advisors with respect to such issues. In particular, we have assumed, with your permission, that the Company will be the acquirer in the Transaction for accounting purposes. We also are not experts in the evaluation of reserves for losses and loss adjustment expenses and were not requested to, and we did not, make any actuarial determinations or evaluations or attempt to evaluate actuarial assumptions. We made no analysis of, and express no view with respect to, the adequacy of the Company’s or Parent’s loss and loss adjustment expense reserves. Representatives of Parent have informed us, and we have further assumed, that the final terms of the Merger Agreement will not differ materially from the terms set forth in the drafts we have reviewed.
 
This opinion has been approved and authorized for issuance by a Deutsche Bank fairness opinion review committee, is addressed to, and for the use and benefit of, the Board of Directors of Parent in connection with and for the purposes of its evaluation of the Transaction and is not a recommendation to the stockholders of Parent as to how they should vote with respect to the Transaction, the amendment of Parent’s Articles of Association or the issuance of Parent Shares in the Transaction, in each case as contemplated by the Merger Agreement. This opinion is limited to the fairness, from a financial point of view of the Exchange Ratio to Parent and does not address any other terms of the Transaction or the Merger Agreement, is subject to the assumptions, limitations, qualifications and other conditions contained herein and is necessarily based on the economic, market and other conditions, and information made available to us, as of the date hereof. You have not asked us to, and this opinion does not, address the fairness of the Transaction, or any consideration received in connection therewith, to the holders of any class of securities, creditors or other constituencies of Parent, nor does it address the fairness of the contemplated benefits of the Transaction. We expressly disclaim any undertaking or obligation to advise any person of any change in any fact or matter affecting our opinion of which we become aware after the date hereof. Deutsche Bank expresses no opinion as to the merits of the underlying decision by Parent to engage in the Transaction or the relative merits of the Transaction as compared to any alternative transactions or business strategies. In addition, we do not express any view or opinion as to the fairness, financial or otherwise, of the amount or nature of any compensation payable to or to be received by any of the officers, directors, or employees of any parties to the Transaction, or any class of such persons, relative to the Exchange Ratio. This opinion does not in any manner address the prices at which Parent’s ordinary shares or other securities will trade following the announcement or consummation of the Transaction.
 
Deutsche Bank will be paid a fee for its services as financial advisor to Parent in connection with the Transaction, a portion of which is contingent upon delivery of this opinion and a substantial portion of which is contingent upon consummation of the Transaction. Parent has also agreed to reimburse Deutsche Bank for

its expenses, and to indemnify Deutsche Bank against certain liabilities, in connection with its engagement. We are an affiliate of Deutsche Bank AG (together with its affiliates, the “DB Group”). One or more members of the DB Group have, from time to time, provided investment banking, commercial banking (including extension of credit) and other financial services to Parent, the Company or their respective affiliates for which it has received compensation, including having acted as a book-running manager in a public offering of senior notes by Parent, acting as a lender of Parent’s senior credit facility and acting as an asset manager for certain investment portfolios of the Company. DB Group may also provide investment and commercial banking services to Parent the Company and their respective affiliates in the future, for which we would expect the DB Group to receive compensation. In the ordinary course of business, members of the DB Group may actively trade in the securities and other instruments and obligations of Parent and the Company (or their respective affiliates) for their own accounts and for the accounts of their customers. Accordingly, the DB Group may at any time hold a long or short position in such securities, instruments and obligations. In addition, as of the date hereof, Deutsche Bank and affiliates own approximately 250,000 shares of Company Common Stock.
 
Based upon and subject to the foregoing assumptions, limitations, qualifications and conditions, it is Deutsche Bank’s opinion as investment bankers that, as of the date hereof, the Exchange Ratio is fair, from a financial point of view, to Parent.
 
This letter is provided to the Board of Directors of the Company in connection with and for the purposes of its evaluation of the Transaction. This opinion may not be disclosed, summarized, referred to, or communicated (in whole or in part) to any other person for any purpose whatsoever except with our prior written approval, provided that this opinion may be reproduced in full in any proxy or information statement required by the Securities and Exchange Commission to be mailed by the Company to its stockholders in connection with the Transaction.
 
Very truly yours,

Members of the Board of Directors:
 
June 12, 2011
 
You have requested our opinion as to the fairness from a financial point of view to the holders of common stock, par value $1.00 per share (the “Company Common Stock”), of Transatlantic Holdings, Inc. (the “Company”) of the Exchange Ratio (as defined below) pursuant to the terms and subject to the conditions set forth in the Agreement and Plan of Merger, dated as of June 12, 2011 (the “Agreement”) to be entered into by the Company, Allied World Assurance Company Holdings, AG (“Allied World”) and GO Sub, LLC, a wholly-owned subsidiary of Allied World (the “Merger Sub”). As more fully described in the Agreement, Merger Sub will be merged with and into the Company (the “Transaction”) and each issued and outstanding share of Company Common Stock will be converted into the right to receive 0.880 (the “Exchange Ratio”) ordinary shares, par value CHF 15.00 per share, of Allied World (the “Allied World Shares”).
 
We have acted as your financial advisor in connection with the Transaction and will receive a fee for our services, a significant portion of which is contingent upon the consummation of the Transaction. We will also receive a fee upon delivery of this opinion. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. Our affiliates, employees, officers and partners may at any time own securities of the Company and Allied World.
 
Our opinion does not address the Company’s underlying business decision to effect the Transaction or the relative merits of the Transaction as compared to any alternative business strategies or transactions that might be available to the Company and does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the Transaction or any other matter. We have not been asked to, nor do we, offer any opinion as to the material terms of the Agreement or the form of the Transaction. We express no opinion as to what the value of Allied World Shares will be when issued pursuant to the Transaction or the prices at which such Allied World Shares will trade in the future. We have assumed, with your consent, that the representations and warranties of all parties to the Agreement are true and correct, that each party to the Agreement will perform all of the covenants and agreements required to be performed by such party, that all conditions to the consummation of the Transaction will be satisfied without waiver thereof and that the Transaction will be consummated in a timely manner in accordance with the terms described in the Agreement, without any modifications or amendments thereto or any adjustment to the Exchange Ratio. In rendering this opinion, we have also assumed, with your consent, that the final executed form of the Agreement does not differ in any material respect from the draft that we have examined. We have also assumed, at your direction, that at the closing of the Transaction the Allied World Shares to be issued to Company stockholders pursuant to the Agreement will be listed on the NYSE. We have not been authorized to solicit and have not solicited indications of interest in a possible transaction with the Company from any party.
 
In arriving at our opinion, we have, among other things: (i) reviewed certain publicly available business and financial information relating to the Company and Allied World that we deemed relevant; (ii) reviewed certain internal information relating to the business, including financial forecasts, earnings, cash flow, assets, liabilities and prospects of the Company, furnished to us by the Company; (iii) reviewed certain internal information relating to the business, including financial forecasts, earnings, cash flow, assets, liabilities and prospects of Allied World, furnished to us by Allied World; (iv) conducted discussions with members of senior management and representatives of the Company and Allied World concerning the matters described in clauses (i) — (iii) of this paragraph, as well as their respective businesses and prospects before and after giving effect to the Transaction; (v) reviewed publicly available financial and stock market data, including valuation multiples, for the Company and Allied World and compared them with those of certain other companies in lines of business that we deemed relevant; (vi) compared the proposed financial terms of the


Table of Contents

Transaction with the financial terms of certain other transactions that we deemed relevant; (vii) reviewed a draft of the Agreement dated June 11, 2011; (viii) participated in certain discussions and negotiations among representatives of the Company and Allied World and their financial and legal advisors and (ix) conducted such other financial studies and analyses and took into account such other information as we deemed appropriate.
 
In connection with our review, we have not assumed any responsibility for independent verification of any of the financial, legal, regulatory, tax, accounting and other information supplied to, discussed with, or reviewed by us for the purpose of this opinion and have, with your consent, relied on such information being complete and accurate in all material respects. In addition, with your consent we have not made any independent evaluation or appraisal of any of the assets or liabilities (contingent, derivative, off-balance-sheet, or otherwise) of the Company or Allied World, nor have we been furnished with any such evaluation or appraisal. We are not experts in the evaluation of reserves for insurance losses and loss adjustment expenses, and we have not made an independent evaluation of the adequacy of reserves of the Company or Allied World. In that regard, with your consent, we have made no analysis of, and express no opinion as to, the adequacy of the loss and loss adjustment expense reserves of, the value of redundant reserves to, or the ability to achieve reserve releases by, the Company or Allied World. We have not been requested, and we have not undertaken, to make any independent valuation of the Company’s pending arbitration matters concerning American International Group, Inc. and certain of its subsidiaries, and for purposes of our analysis we have, at your direction, assumed the Company will obtain a recovery in the amount and at the time estimated by Company management. In addition, with respect to the forecasted financial information referred to above, we have assumed at your direction that it has been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company and Allied World as to the future performance of their respective companies and that such future financial results will be achieved at the times and in the amounts projected by management of the Company and Allied World.
 
Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof. We have assumed, with your consent, that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without the imposition of any delay, limitation, restriction, divestiture or condition that would have an adverse effect on the Company or Allied World or on the expected benefits of the Transaction.
 
This opinion is for the use and benefit of the Board of Directors of the Company in its evaluation of the Transaction and may not be disclosed to any person without our prior written consent. In addition, you have not asked us to address, and this opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of the Company, other than the holders of Company Common Stock.
 
In addition, we do not express any opinion as to the fairness of the amount or nature of any compensation to be received by any of the Company’s officers, directors or employees, or any class of such persons, relative to the Exchange Ratio. This opinion was approved by a Moelis & Company LLC fairness opinion committee.
 
Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio pursuant to the Agreement is fair, from a financial point of view, to the holders of Company Common Stock.
 
Very truly yours,

Die Amtsdauer läuft mit dem Tag der nächsten ordentlichen Generalversammlung ab, vorbehältlich vorgängigen Rücktritts oder Abwahl. Wenn vor Ablauf dieser Amtsdauer Verwaltungsräte ersetzt werden, läuft die Amtsdauer der neu hinzu gewählten Mitglieder mit der ordentlichen Amtsdauer ihrer Vorgänger ab.   a)   The Board of Directors shall consist of a minimum of three and a maximum of thirteen members.

    Unabhängig von vorstehender Bestimmung schiesst die Gesellschaft den Mitgliedern des Verwaltungsrats sowie der Geschäftsleitung die im Zusammenhang mit oben erwähnten Angelegenheiten entstehenden Gerichts- und Anwaltskosten vor. Ausgenommen sind jene Fälle, in denen die Gesellschaft selbst gegen die betreffenden Personen vorgeht. Die Gesellschaft kann die aufgewendeten Auslagen zurückfordern, wenn ein Gericht oder eine andere zuständige Behörde rechtskräftig feststellt, dass die betreffende Person gegenüber der Gesellschaft eine Pflichtverletzung begangen hat.       Without limiting the foregoing paragraph, the Company shall advance court costs and attorney’s fees to the members of the Board of Directors and officers, except in cases where the Company itself is plaintiff. The Company may however recover such advanced cost if a court or another competent authority holds that the member of the Board of Directors or the officer in question has breached its duties to the Company.

If at any time such a committee has not been so designated or is not acting, the Board shall constitute the Committee. Any action by the Board with respect to a Section 162(m) Award will be made only by members of the Board who are outside directors to the extent required by and in compliance with Section 162(m). The Committee is authorized, subject to the provisions of the Plan and applicable law, to establish such rules and regulations as it deems necessary for the proper administration of the Plan and to make such determinations and interpretations and to take such action in connection with the Plan and any Award granted thereunder as it deems necessary or advisable. All determinations and interpretations made by the Committee shall be final, binding and conclusive on all grantees and on their legal representatives and beneficiaries. The Committee shall have the authority, in its absolute discretion, subject to approval by the Board to the extent required by applicable law, to determine the persons who shall receive Awards, the time when Awards shall be granted, the terms of such Awards and the number of Registered Shares, if any, which shall be subject to such Awards. Unless otherwise provided in an Award Agreement, the Committee shall have the authority, in its absolute discretion, subject to approval by the Board to the extent required by applicable law, to (i) amend any outstanding Award Agreement in any respect, whether or not the rights of the grantee of such Award are adversely affected, including, without limitation, to accelerate the time or times at which the Award becomes vested, unrestricted or may be exercised, waive or amend any goals, restrictions or conditions set forth in such Award Agreement, or impose new goals, restrictions and conditions, or reflect a change in the grantee’s circumstances; and (ii) determine whether, to what extent and under what circumstances and method or methods (A) Awards may be (1) settled in cash, Registered Shares, other securities, other Awards or other property or (2) canceled, forfeited or suspended, (B) Registered Shares, other securities, other Awards or other property, and other amounts payable with respect to an Award may be deferred either automatically or at the election of the grantee thereof or of the Committee and (C) Awards may be settled by the Company or any of its designees. Notwithstanding anything to the contrary contained herein, the Board may, in its sole discretion, at any time and from time to time, grant Awards (including grants to members of the Board who are not employees of the Company) or


E-2


Table of Contents

administer the Plan, in which case the Board shall have all of the authority and responsibility granted to the Committee herein.
 
1.3.2 Actions of the Committee may be taken by the vote of a majority of its members. The Committee may allocate among its members and delegate to any person who is not a member of the Committee any of its powers, responsibilities or duties, but only to the extent in accordance with applicable law, including Section 162(m), to the extent applicable.
 
1.3.3 No member of the Board or the Committee or any employee of the Company (each such person a “Covered Person”) shall have any liability to any person (including any grantee) for any action taken or omitted to be taken or any determination made in good faith with respect to the Plan or any Award. Each Covered Person shall be indemnified and held harmless by TransAllied against and from any loss, cost, liability or expense (including attorneys’ fees) that may be imposed upon or incurred by such Covered Person in connection with or resulting from any action, suit or proceeding to which such Covered Person may be a party or in which such Covered Person may be involved by reason of any action taken or omitted to be taken or any determination made in good faith under the Plan or any Award Agreement and against and from any and all amounts paid by such Covered Person, with TransAllied’s approval, in settlement thereof, or paid by such Covered Person in satisfaction of any judgment in any such action, suit or proceeding against such Covered Person; provided that TransAllied shall have the right, at its own expense, to assume and defend any such action, suit or proceeding and, once TransAllied gives notice of its intent to assume the defense, TransAllied shall have sole control over such defense with counsel of TransAllied’s choice. The foregoing right of indemnification shall not be available to a Covered Person to the extent that a court of competent jurisdiction in a final judgment or other final adjudication, in either case, not subject to further appeal, determines that the acts or omissions or determinations of such Covered Person giving rise to the indemnification claim resulted from such Covered Person’s fraud or dishonesty. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which Covered Persons may be entitled under TransAllied’s Articles of Association or Organizational Regulations, as a matter of law, or otherwise, or any other power that TransAllied may have to indemnify such persons or hold them harmless.
 
1.4  Persons Eligible for Awards
 
Awards under the Plan may be made to such officers, directors, employees (including prospective employees), consultants and other individuals who may perform services for the Company, as the Committee may select.
 
1.5  Types of Awards Under Plan
 
Awards may be made under the Plan in the form of (a) restricted stock, (b) restricted stock units, (c) dividend equivalent rights and (d) other equity-based or equity-related Awards that the Committee determines to be consistent with the purposes of the Plan and the interests of the Company. TransAllied, however, will not grant stock options pursuant to the Plan.
 
1.6  Registered Shares Available for Awards
 
1.6.1 Subject to adjustment as provided in Section 1.6.2 hereof, the maximum number of shares that may be issued under the Plan is four million (4,000,000) Registered Shares. Such Registered Shares may, in the discretion of the Committee, be either authorized but unissued shares or shares previously issued and reacquired by TransAllied. If any Award shall expire, terminate or otherwise lapse, in whole or in part, any Registered Shares subject to such Award (or portion thereof) shall again be available for issuance under the Plan. Any Registered Shares delivered by TransAllied, any Registered Shares with respect to which Awards are made by TransAllied and any Registered Shares with respect to which TransAllied becomes obligated to make Awards, through the assumption of, or in substitution for, outstanding awards previously granted by an acquired entity, shall not be counted against the shares available for Awards under this Plan.
 
1.6.2 The Committee shall adjust the number of Registered Shares authorized pursuant to Section 1.6.1 and 1.6.3 and the terms of the Plan and any outstanding Awards (including, without limitation, the number of Registered Shares covered by each outstanding Award, the type of property to which the Award is subject, the


E-3


Table of Contents

exercise or strike price of any Award and any applicable performance measures under any Award (including without limitation, Performance Measures and Performance Goals), in each case, in such manner as it deems appropriate to preserve the benefits or potential benefits intended to be made available to grantees of Awards, for any increase or decrease in the number of issued Registered Shares resulting from a recapitalization, stock split, stock dividend, combination or exchange of Registered Shares, merger, amalgamation, consolidation, rights offering, separation, reorganization or liquidation, or any other change in the corporate structure or shares of TransAllied. After any adjustment made pursuant to this Section 1.6.2, the number of Registered Shares subject to each outstanding Award shall be rounded down to the nearest whole number. Notwithstanding the foregoing, in the event of (i) a merger, amalgamation or consolidation involving TransAllied in which TransAllied is not the surviving corporation; (ii) a merger, amalgamation or consolidation involving TransAllied in which TransAllied is the surviving corporation but the holders of shares of Registered Shares receive securities of another corporation and/or other property, including cash; (iii) a the sale of greater than fifty percent (50%) of the securities of TransAllied entitled to vote in the election of directors to the Board; or (iv) the reorganization or liquidation of TransAllied (each, a “Corporate Event”), in lieu of providing the adjustment set forth above, the Committee may, in its discretion, provide that all outstanding Awards shall terminate as of the consummation of such Corporate Event, and either (x) accelerate the vesting of, and cause all vesting restrictions to lapse on, all outstanding Awards to a date at least ten days prior to the date of such Corporate Event, or (y) provide that holders of Awards will receive a payment in respect of cancellation of their Awards based on the amount of the per share consideration being paid for the Registered Shares in connection with such Corporate Event. Payments to holders pursuant to the preceding sentence shall be made in cash, or, in the sole discretion of the Committee, in such other consideration necessary for a holder of an Award to receive property, cash or securities as such holder would have been entitled to receive upon the occurrence of the transaction if the holder had been, immediately prior to such transaction, the holder of the number of Registered Shares covered by the Award at such time. Notwithstanding anything herein to the contrary, an adjustment to a Section 162(m) Award under this Section 1.6.2 may not be made in a manner that would cause the modified award to result in a loss of deduction under Section 162(m), unless the Committee determines that such adjustment is desirable notwithstanding such loss of deduction.
 
1.6.3 There shall be no limit on the amount of cash, securities (other than Registered Shares as provided in this Section 1.6) or other property that may be delivered pursuant to the Plan or any Award; provided, however, that during any time that the Company is subject to Section 162(m), the maximum number of Registered Shares with respect to which Awards may be granted to any individual in any one year shall not exceed the maximum number of Registered Shares authorized for issue hereunder, as such number may change from time to time.
 
ARTICLE II
 
AWARDS UNDER THE PLAN
 
2.1  Agreements Evidencing Awards
 
Each Award granted under the Plan shall be evidenced by a written document that shall contain such provisions and conditions as the Committee deems appropriate. The Committee may grant Awards in tandem with or in substitution for any other Award or Awards granted under this Plan or any award granted under any other plan of the Company. By accepting an Award pursuant to the Plan, a grantee thereby agrees that the Award shall be subject to all of the terms and provisions of the Plan and the applicable Award Agreement.
 
2.2  No Rights as a Shareholder
 
No grantee of an Award shall have any of the rights of a shareholder of TransAllied with respect to Registered Shares subject to such Award until the delivery of such shares. Except as otherwise provided in Section 1.6.2, no adjustments shall be made for dividends, distributions or other rights (whether ordinary or extraordinary, and whether in cash, Registered Shares, other securities or other property) for which the record date is prior to the date such shares are delivered.

Table of Contents

2.3  Grant of Restricted Registered Shares
 
The Committee may grant or offer for sale restricted Registered Shares in such amounts and subject to Section 2.8 and such terms and conditions as the Committee shall determine. Upon the delivery of such shares, the grantee shall have the rights of a shareholder with respect to the restricted stock, subject to Section 2.8 and any other restrictions and conditions as the Committee may include in the applicable Award Agreement. In the event that a Certificate is issued in respect of restricted Registered Shares, such Certificate may be registered in the name of the grantee but may be held by TransAllied or its designated agent until the time the restrictions lapse.
 
2.4  Grant of Restricted Stock Units
 
The Committee may grant Awards of restricted stock units in such amounts and subject to Section 2.8 and such terms and conditions as the Committee shall determine. A grantee of a restricted stock unit will have only the rights of a general unsecured creditor of TransAllied until delivery of Registered Shares, cash or other securities or property is made as specified in the applicable Award Agreement. On the delivery date specified in the Award Agreement, the grantee of each restricted stock unit not previously forfeited or terminated shall receive one Registered Share, or cash, securities or other property equal in value to a Registered Share or a combination thereof as specified by the Committee.
 
2.5  Grant of Dividend Equivalent Rights
 
The Committee may include in the Award Agreement with respect to any Award a dividend equivalent right entitling the grantee to receive amounts equal to all or any portion of the dividends that would be paid on the Registered Shares covered by such Award if such shares had been delivered pursuant to such Award. The grantee of a dividend equivalent right will have only the rights of a general unsecured creditor of TransAllied until payment of such amounts is made as specified in the applicable Award Agreement. In the event such a provision is included in an Award Agreement, the Committee shall determine whether such payments shall be made in cash, in Registered Shares or in another form, whether they shall be conditioned upon the exercise of the Award to which they relate, the time or times at which they shall be made, and such other terms and conditions as the Committee shall deem appropriate.
 
2.6  Other Stock-Based Awards
 
The Committee may grant other types of equity-based or equity-related Awards (including the grant or offer for sale of unrestricted Registered Shares) in such amounts and subject to such terms and conditions, as the Committee shall determine. Such Awards may entail the transfer of actual Registered Shares to Award recipients, or payment in cash or otherwise of amounts based on the value of Registered Shares, and may include, without limitation, Awards designed to comply with or take advantage of the applicable local laws of jurisdictions other than the United States.
 
2.7  Performance-Based Awards
 
The Committee shall have authority to designate Awards as performance-based, the attainment of which shall be based on the achievement of performance goals during performance periods. In order for a performance-based Award to be a Section 162(m) Award, the Committee shall establish in writing (including approved minutes of the Committee), within the first 90 days of a Performance Period (or, if applicable, within the maximum period allowed under Section 162(m)), (i) which grantees will be eligible to receive Section 162(m) Awards in respect of such Performance Period, (ii) the types of Awards to be issued, (iii) the Performance Measure(s) to be used to establish the Performance Goal(s), (iv) the objective Performance Goals that must be met with respect to such Performance Period, and (v) any other terms and conditions that the Committee deems appropriate and consistent with this Plan and the requirements of Section 162(m).
 
In addition to such other limitations as may be established by the Committee, a grantee shall be eligible to receive payment in respect of a Section 162(m) Award only to the extent that, following the completion of the Performance Period, the Committee shall have met to review and shall have certified in writing (including approved minutes of the Committee) whether, and to what extent, the Performance Goals for the Performance Period have been achieved and, if so met, to calculate and certify in writing the amount of the Section 162(m)


E-5


Table of Contents

Awards earned for the Performance Period. The Committee shall then determine the amount of each grantee’s Section 162(m) Award for the Performance Period and, in so doing, may apply discretion to eliminate or reduce the amount of a Section 162(m) Award, if and when it deems appropriate; provided that the exercise of such discretion would not cause the Section 162(m) Award to fail to be “qualified performance-based compensation” under Section 162(m). The Committee also has the authority to provide for accelerated vesting of any Award based on the achievement of Performance Goals pursuant to the Performance Measures specified in the Award Agreement. Except as otherwise provided by the Committee in an Award Agreement, the performance-based Awards are intended to constitute short term deferrals within the meaning of Section 409A.
 
2.8  Certain Restrictions
 
In the case of an Award in the form of restricted stock or restricted stock units, at least one year must elapse before the delivery or payment of Registered Shares, cash or other property, except in the case of (i) termination of employment due to death, disability, retirement at or after age 65 or change of control; or (ii) an Award that the Committee determines is performance based.
 
ARTICLE III
 
MISCELLANEOUS
 
3.1  Amendment of the Plan
 
3.1.1 Unless otherwise provided in an Award Agreement, the Board may from time to time suspend, discontinue, revise or amend the Plan in any respect whatsoever, including in any manner that adversely affects the rights, duties or obligations of any grantee of an Award.
 
3.1.2 Unless otherwise determined by the Board, shareholder approval of any suspension, discontinuance, revision or amendment shall be obtained only to the extent necessary to comply with any applicable law or stock exchange listing requirement.
 
3.2  Confidentiality
 
In consideration of the grantee’s acceptance of any Award, the grantee hereby agrees to keep confidential the existence of, and any information concerning, any dispute arising in connection with any Award, the Plan and any related matters, except that the grantee may disclose information concerning such dispute to the court that is considering such dispute or to the grantee’s legal counsel (provided that such counsel agrees not to disclose any such information other than as necessary to the prosecution or defense of the dispute).
 
3.3  Tax Withholding
 
As a condition to the delivery of any Registered Shares pursuant to any Award or the lifting or lapse of restrictions on any Award, or in connection with any other event that gives rise to a federal or other governmental tax withholding obligation on the part of the Company relating to an Award (including, without limitation, FICA tax), (a) the Company may deduct or withhold (or cause to be deducted or withheld) from any payment or distribution to a grantee whether or not pursuant to the Plan or (b) the Committee shall be entitled to require that the grantee remit cash to the Company (through payroll deduction or otherwise), in each case in an amount sufficient in the opinion of the Company to satisfy such withholding obligation.
 
3.4  Required Consents and Legends
 
3.4.1 If the Committee shall at any time determine that any consent (as hereinafter defined) is necessary or desirable as a condition of, or in connection with, the granting of any Award, the delivery of Registered Shares or the delivery of any cash, securities or other property under the Plan, or the taking of any other action thereunder (each such action being hereinafter referred to as a “plan action”), then such plan action shall not be taken, in whole or in part, unless and until such consent shall have been effected or obtained to the full satisfaction of the Committee. The Committee may direct that any Certificate evidencing shares delivered pursuant to the Plan shall bear a legend setting forth such restrictions on transferability as the


E-6


Table of Contents

Committee may determine to be necessary or desirable, and may advise the transfer agent to place a stop transfer order against any legended shares.
 
3.4.2 The term “consent” as used in this Section 3.4 with respect to any plan action includes (a) any and all listings, registrations or qualifications in respect thereof upon any securities exchange or under any federal, state or local law, or law, rule or regulation of a jurisdiction outside the United States; (b) or any other matter, which the Committee may deem necessary or desirable to comply with the terms of any such listing, registration or qualification or to obtain an exemption from the requirement that any such listing, qualification or registration be made; (c) any and all other consents, clearances and approvals in respect of a plan action by any governmental or other regulatory body or any stock exchange or self-regulatory agency; and (d) any and all consents required by the Committee. Nothing herein shall require TransAllied to list, register or qualify the Registered Shares on any securities exchange.
 
3.5  Nonassignability; No Hedging
 
Except to the extent otherwise expressly provided in the applicable Award Agreement or determined by the Committee, no Award (or any rights and obligations thereunder) granted to any person under the Plan may be sold, exchanged, transferred, assigned, pledged, hypothecated or otherwise disposed of or hedged, in any manner (including through the use of any cash-settled instrument), whether voluntarily or involuntarily and whether by operation of law or otherwise, other than by will or by the laws of descent and distribution, and all such Awards (and any rights thereunder) shall be exercisable during the life of the grantee only by the grantee or the grantee’s legal representative. Any sale, exchange, transfer, assignment, pledge, hypothecation or other disposition in violation of the provisions of this Section 3.5 shall be null and void and any Award which is hedged in any manner shall immediately be forfeited. All of the terms and conditions of this Plan and the Award Agreements shall be binding upon any permitted successors and assigns.
 
3.6  Successor Entity
 
Unless otherwise provided in the applicable Award Agreement and except as otherwise determined by the Committee, in the event of a merger, amalgamation, consolidation, mandatory share exchange or other similar business combination of TransAllied with or into any other entity or any transaction in which another person or entity acquires all of the issued and outstanding Registered Shares of TransAllied, or all or substantially all of the assets of TransAllied, outstanding Awards may be assumed or a substantially equivalent award may be substituted by such successor entity or a parent or subsidiary of such successor entity.
 
3.7  Right of Discharge Reserved
 
Nothing in the Plan or in any Award Agreement shall confer upon any grantee the right to continued Employment by the Company or affect any right that the Company may have to terminate such Employment.
 
3.8  Nature of Payments
 
3.8.1 Any and all grants of Awards and deliveries of Registered Shares, cash, securities or other property under the Plan shall be in consideration of services performed or to be performed for the Company by the grantee. Awards under the Plan may, in the discretion of the Committee, be made in substitution in whole or in part for cash or other compensation otherwise payable to a grantee by the Company. Only whole Registered Shares shall be delivered under the Plan. Awards shall, to the extent reasonably practicable, be aggregated in order to eliminate any fractional shares. Fractional shares shall be rounded down to the nearest whole share and any such fractional shares shall be forfeited.
 
3.8.2 All such grants and deliveries shall constitute a special discretionary incentive payment to the grantee and shall not be required to be taken into account in computing the amount of salary or compensation of the grantee for the purpose of determining any contributions to or any benefits under any pension, retirement, profit-sharing, bonus, life insurance, severance or other benefit plan of the Company or under any agreement with the grantee, unless the Company specifically provides otherwise.

3.9  Non-Uniform Determinations
 
The Committee’s determinations under the Plan and Award Agreements need not be uniform and may be made by it selectively among persons who receive, or are eligible to receive, Awards under the Plan (whether or not such persons are similarly situated). Without limiting the generality of the foregoing, the Committee shall be entitled, among other things, to make non-uniform and selective determinations under Award Agreements, and to enter into non-uniform and selective Award Agreements, as to (a) the persons to receive Awards, (b) the terms and provisions of Awards and (c) whether a grantee’s Employment has been terminated for purposes of the Plan.

3.14  Severability; Entire Agreement
 
If any of the provisions of this Plan or any Award Agreement is finally held to be invalid, illegal or unenforceable (whether in whole or in part), such provision shall be deemed modified to the extent, but only to the extent, of such invalidity, illegality or unenforceability and the remaining provisions shall not be affected thereby; provided, that if any of such provisions is finally held to be invalid, illegal or unenforceable because it exceeds the maximum scope determined to be acceptable to permit such provision to be enforceable, such provision shall be deemed to be modified to the minimum extent necessary to modify such scope in order to make such provision enforceable hereunder. The Plan and any Award Agreements contain the entire agreement of the parties with respect to the subject matter thereof and supersede all prior agreements, promises, covenants, arrangements, communications, representations and warranties between them, whether written or oral with respect to the subject matter thereof.
 
3.15  Waiver of Claims
 
Each grantee of an Award recognizes and agrees that prior to being selected by the Committee to receive an Award he or she has no right to any benefits hereunder. Accordingly, in consideration of the grantee’s receipt of any Award hereunder, he or she expressly waives any right to contest the amount of any Award, the terms of any Award Agreement, any determination, action or omission hereunder or under any Award Agreement by the Committee, TransAllied or the Board, or any amendment to the Plan or any Award Agreement (other than an amendment to this Plan or an Award Agreement to which his or her consent is expressly required by the express terms of an Award Agreement).

Item 20.   Indemnification of Directors and Officers
 
The following summary is qualified in its entirety by reference to the complete text of the Allied World Articles.
 
The Allied World Articles provide that Allied World shall indemnify and hold harmless, to the fullest extent permitted by Swiss law, each of the members of the Allied World board of directors and officers out of the assets of Allied World from and against all actions, costs, charges, losses, damages and expenses which they or any of them may incur or sustain by or by reason of any act done, concurred in or omitted in or about the execution of their duty, or supposed duty on behalf of Allied World; provided that this indemnity shall not extend to any matter in which any of said persons is found, in a final judgment or decree not subject to appeal, to have committed with intent or gross negligence.
 
Without limiting the foregoing paragraph, Allied World shall advance court costs and attorney’s fees to the members of the Allied World board of directors and officers, except in cases where Allied World itself is plaintiff. Allied World may, however, recover such advanced cost if a court or another competent authority holds that the member of the Allied World board of directors or the officer in question has breached its duties to Allied World.

Item 22.   Undertakings
 
The undersigned registrant hereby undertakes:
 
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement (notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement); and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.
 
(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.


II-2


Table of Contents

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
 
(4) That, for the purpose of determining liability under the Securities Act to any purchaser, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act, (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(5) That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.
 
(6) That every prospectus (i) that is filed pursuant to paragraph (5) above, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as part of an amendment to this registration statement and will not be used until such amendment has become effective, and that for the purpose of determining liabilities under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(7) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.
 
(8) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.
 
(9) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
 
(10) The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.
