Item 8.01. Other Events.
AmerUs Group Co. (the “Company”) has scheduled a special meeting of its shareholders for October 19, 2006 at the Company’s offices in Des Moines for the purpose of considering and approving an agreement and plan of merger that the Company entered into on July 12, 2006 providing for the merger of an indirect wholly owned subsidiary of Aviva plc (“Aviva”) with and into the Company. All Company common shareholders of record at the close of business on September 8, 2006 will be entitled to notice of, and to vote at, the special meeting and any adjournment or postponement of the special meeting.
The Company and Aviva each filed pre-merger notifications with the U.S. antitrust authorities pursuant to the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended. The waiting period expired at 11:59 p.m. on September 6, 2006 without the Federal Trade Commission and the Department of Justice Antitrust Division taking further action.
Under the terms of the merger agreement, the Company’s common stockholders will receive $69.00 per share in cash for each share of common stock. The closing of the merger is conditioned upon, among other things, the common shareholder approval and required government and regulatory approvals. Although there can be no assurances, the Company expects the transaction to close before December 31, 2006.
On September 7, 2006, the Company posted an interview with Thomas C. Godlasky, the Company’s Chairman, President & CEO, on the Company’s internal website, a transcript of which is attached to this Current Report on Form 8-K as Exhibit 99.1.

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.
