Item 8.01. Other Events.
On August 11, 2006, Aviva plc (“Aviva”) submitted Form A applications regarding the proposed indirect acquisition of the following life insurance companies owned, directly or indirectly, by AmerUs Group Co. (“AmerUs Group”): (i) AmerUs Life Insurance Company, (ii) American Investors Life Insurance Company, Inc., (iii) Financial Benefit Life Insurance Company, (iv) Indianapolis Life Insurance Company and (v) Bankers Life Insurance Company of New York.
The Form A application is filed in the domiciliary state of an insurance company and is the form pursuant to which an acquiring party seeks approval of the acquisition from the state’s Department of Insurance. Accordingly, filings were made in Iowa, Kansas, Indiana and New York.
As previously announced on July 13, 2006, Aviva will pay $69.00 per share in cash for each outstanding share of AmerUs Group common stock once the acquisition is completed.
The transaction, which was unanimously approved by the boards of directors of Aviva and AmerUs Group, is subject to customary closing conditions, including approval by AmerUs Group shareholders and the receipt of government and regulatory approvals, including approval of the Form A applications discussed above and the expiration of all waiting periods required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Although there can be no assurances, we expect the transaction to close before December 31, 2006.
AmerUs Group is publicly traded on the New York Stock Exchange under the symbol “AMH.” Its headquarters are in Des Moines, Iowa, USA

Cautionary Statement Regarding Forward-Looking Statements
This document contains statements which constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, which include words such as “anticipate,” “believe,” “plan,” “estimate,” “expect,” “intend,” and other similar and related expressions. Forward-looking statements are made based upon management’s current expectations and beliefs concerning future developments and their potential effects on AmerUs Group. Such forward-looking statements are not guarantees of future events. Actual results may differ materially from those contemplated by the forward-looking statements due to, among others, the following factors: (1) the shareholders of AmerUs Group may not approve the merger agreement at the special shareholder meeting; (2) the parties may be unable to obtain governmental and regulatory approvals required for the merger, or required governmental and regulatory approvals may delay the merger or result in the imposition of conditions that could cause the parties to abandon the merger; (3) the parties may be unable to complete the merger because, among other reasons, conditions to the closing of the merger may not be satisfied or waived; or (4) other factors that may be referred to in AmerUs Group’s reports filed with or furnished to the Securities and Exchange Commission from time to time. There can be no assurance that other factors not currently anticipated by AmerUs Group will not materially and adversely affect future events. Security holders are cautioned not to place undue reliance on any forward-looking statements made by AmerUs Group or on its behalf. Forward-looking statements speak only as of the date the statement was made. AmerUs Group undertakes no obligation to update or revise any forward-looking statement.
