Filed by: AmerUs Group Co.
Pursuant to Rule 14a-12
under the Securities Exchange Act of 1934
Subject Company: AmerUs Group Co.
Commission File No. 001-15166
On July 26, 2006, AmerUs Group Co. (the “Company”) posted the following questions and answers on its internal website. These questions and answers provide the Company’s employees with information on the acquisition of the Company by Aviva plc.
Aviva Acquisition
Questions and Answers
July 25, 2006
1. What aspirations does Aviva have in the US other than AmerUs?
Aviva believes AmerUs Group provides an excellent platform that can achieve substantial growth in the U.S. marketplace. As such, no additional acquisitions in the U.S. are currently being considered.
In fact, Richard Harvey, Aviva plc’s Group Chief Executive, had the following quote in The Financial Times, when asked by reporters if Aviva planned additional U.S. acquisitions: “That is not the case. This achieves our ambitions in the US. Its size makes that clear.”
2. Will stockholders vote on this acquisition? If so, and there is a negative vote, what happens?
Under the Iowa Business Corporation Act, the acquisition must be approved by a majority of the votes of the holders of our common stock cast at a special meeting of AmerUs Group’s shareholders, provided that a quorum is present. A quorum exists if at least a majority of the votes entitled to be cast at the special meeting are present in person or by proxy. We currently expect to hold a special meeting of shareholders during the fourth quarter of 2006. Shareholder approval, in addition to various governmental and regulatory approvals, is required in order to complete the transaction. If the shareholders do not approve the transaction, AmerUs Group would continue as an independent, publicly traded company.
3. Will our common stock still be listed on the New York Stock Exchange?
Since the offer from Aviva is for $69 per share in cash, once the acquisition is completed AmerUs Group will ‘delist’ its common stock from the New York Stock Exchange and our shares of common stock will no longer be traded on any stock exchange.
4. It was mentioned growing the office in Des Moines. Will the Boston company move to Des Moines? What about the offices in Indianapolis, New York, and Topeka?
As part of the integration work, functions at the Boston location, as well as all AmerUs Group locations, will be reviewed in order to maximize synergies and eliminate redundancies. It is expected that every location will experience change as a result of the integration work. The type and number of positions at each location has not yet been determined.



5. What is the approximate time until a change plan begins? When will we hear of elimination of “redundancies”?
Integration teams will be developed as soon as possible to review all business processes. We expect the initial teams to be formed after antitrust clearance, which is currently expected around the end of August. Consistent with our past practice, we will provide you with information as soon as any decisions have been made.
6. Will there be a hiring freeze during the integration process?
A hiring freeze is not expected to be implemented. Within the organization, we continue to have strategic, key positions that need to be filled. However, due to the pending transaction, some open positions may be placed ‘on hold’ until integration teams have evaluated our current staffing levels and business processes.
7. How will the acquisition affect our retirement/401K plan?
As part of the definitive agreement, it was determined that no significant changes, in the aggregate, will be made to our employee compensation and benefit programs (including the 401(k)) for a period of 24 months following the closing. The programs will be reviewed during this period of time with the intent of synchronizing the Aviva USA and AmerUs programs. Both companies currently offer competitive pay and benefit programs and plan to continue to do so.
Please remember that in the ordinary course of business AmerUs evaluates compensation administration and benefit plan programs on an annual basis in order to remain competitive and manage costs. As a result, changes comparable to those that have occurred in the past can be expected to also take place in 2007.
8. Will we still get our bonus?
As part of the definitive agreement it was agreed that bonuses will be paid in 2007 for 2006 results. As always, bonus payments are not automatically paid, and are based on the bonus pool and individual performance during the year.
