These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Plan's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2004 and 2003, and the changes in its net assets available for benefits for the years then ended, in conformity with U.S. generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2004, is presented for purposes of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ Ernst & Young LLP Des Moines, Iowa May 2, 2005 1 All * AmerUs Savings and Retirement Plan Statements of Net Assets Available for Benefits DECEMBER 31 2004 2003 ------------ ------------ ASSETS Investments $119,456,165 $106,737,373 Employer contributions receivable 2,816,210 3,261,690 ------------ ------------ Net assets available for benefits $122,272,375 $109,999,063 ============ ============ See accompanying notes. 2 All * AmerUs Savings and Retirement Plan Statements of Changes in Net Assets Available for Benefits YEAR ENDED DECEMBER 31 2004 2003 -------------- --------------- Additions: Investment income: Interest and dividends $ 4,107,497 $ 2,716,906 Net unrealized and realized gains on investments 9,588,788 15,328,428 -------------- -------------- 13,696,285 18,045,334 Contributions: Employer 5,842,127 6,339,869 Employees 4,398,265 4,529,375 -------------- -------------- 10,240,392 10,869,244 Transfer of net assets from other plans 1,143,570 789,280 Transfer of net assets resulting from plan merger - 1,642,972 -------------- -------------- Total additions 25,080,247 31,346,830 Deductions: Benefits paid to participants (12,806,935) (7,497,958) -------------- -------------- Net additions 12,273,312 23,848,872 Net assets available for benefits at beginning of year 109,999,063 86,150,191 -------------- -------------- Net assets available for benefits at end of year $ 122,272,375 $ 109,999,063 ============== ============== See accompanying notes. 3 All * AmerUs Savings and Retirement Plan Notes to Financial Statements December 31, 2004 1. DESCRIPTION OF PLAN The following description of the All * AmerUs Savings and Retirement Plan (the Plan) provides only general information. Participants should refer to the plan agreement for a more complete description of the Plan's provisions. GENERAL The Plan is a contributory defined contribution plan covering all employees of AmerUs Group Co., (the Company or AmerUs). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Effective April 1, 2003, the CMIC 401(k) Profit Sharing Plan of Creative Marketing International Corporation merged into the Plan. Creative Marketing International Corporation is wholly owned by AmerUs Annuity Group, which is wholly owned by AmerUs Group Co. ELIGIBILITY Employees are eligible to participate the first of the month coinciding with, or next following, their hire date. Full-time employees and part-time employees who are scheduled to work fewer than 20 hours per week are eligible if the employee has earned 1,000 hours of service during (a) the one-year period which commences on the employee's date of employment, or (b) any Plan year subsequent to the employee's date of employment. CONTRIBUTIONS Participants may contribute up to 50% of annual base salary, overtime pay, short-term disability plan payments, and bonuses (W-2 compensation), but excluding sign-on bonuses, long-term incentives, moving expenses, severance payments, flexible benefit credits taken in cash, car allowances, fitness reimbursements, holiday bonuses and exam awards. In addition, participants may contribute flexible benefit credits to the Plan as pretax contributions. Contributions of flexible benefit credits shall be made at the time and in the manner specified in the flexible benefit plan. The amount contributed per year shall not exceed $13,000 in 2004 and $12,000 in 2003. The annual contribution to all retirement benefit plans shall not exceed the lesser of $41,000 or 100% of the participant's compensation in 2004, subject to certain limitations. 4 All * AmerUs Savings and Retirement Plan Notes to Financial Statements (continued) 1. DESCRIPTION OF PLAN (CONTINUED) Any individual who becomes an eligible employee for the first time (or again becomes an eligible employee after a period of ineligibility) and does not make any election of before-tax contributions, will default to a 2% of compensation contribution election to the Plan. The Company contributes 125% of the participant's contribution up to the first 4% of pay contributed, which is called the "company match." The Company also contributes 4% of compensation as of the end of the Plan year, which is called a "core contribution." The Company's "core contribution" is made as a combination of cash and Company stock, with the cash portion being contributed to the Money Purchase Pension component of the Plan and the stock portion being contributed to the Employee Stock Ownership (ESOP) component of the Plan. An eligible employee previously participating under a Company defined benefit plan may also be eligible for an annual company-provided interim benefit supplement contribution. Each business unit within the Company could elect a "profit sharing contribution" to be allocated among participants employed by the business unit. PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution, the Company's contribution, and an allocation of Plan net earnings. Allocations of net earnings are based on account balances, as defined. Forfeited balances of terminated participants' non-vested accounts are used to reduce future Company contributions. The benefit to which a participant is entitled is the vested benefit that could be provided from the participant's account. VESTING A participant's interest in pre-tax employee contributions and rollover contributions is fully vested and nonforfeitable at all times. After one year of service, all participants (excluding CMIC participants) are fully vested in the portion of the participant's account attributable to employer matching contributions. CMIC participants previously covered under the CMIC Plan shall retain their vested interest in their employer matching and discretionary profit sharing contributions, per the terms of the CMIC Plan in effect immediately prior to April 1, 2003. CMIC participants employed after April 1, 2003 will vest in employee matching contributions according to a five year graded schedule. After five years of service, the participant is fully vested in the core contribution, profit sharing contributions, and any interim benefit supplement. 5 All * AmerUs Savings and Retirement Plan Notes to Financial Statements (continued) 1. DESCRIPTION OF PLAN (CONTINUED) PAYMENT OF BENEFITS On termination of service, a participant may elect to receive a lump-sum amount equal to the value of the participant's account; regular installments paid monthly, quarterly, or annually over a period designated or dollar amount specified by the participant, not to exceed the participant's life expectancy; a joint and 50% survivor annuity for the lives of the participant and spouse, which is purchased from a life insurance company with the proceeds from the participant's account; or a participant may elect to rollover the value of the account into another company's plan or into an established individual retirement account.

The minimum borrowing is $1,000. The loans bear interest at a rate equal to the prime rate published in the Wall Street Journal on the first business day of the month in which the loan was made. PLAN TERMINATION Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts. ADMINISTRATIVE EXPENSES The Company pays all expenses of the Plan, with the exception of loan origination fees, which are charged directly to the participant's account. 8 All * AmerUs Savings and Retirement Plan Notes to Financial Statements (continued) 2. SIGNIFICANT ACCOUNTING POLICIES INVESTMENT VALUATION AND INCOME RECOGNITION Investments in mutual funds and common stock of AmerUs are reported at fair value, based upon the latest quoted market price. Participant loans are valued at their unpaid principal balance, representing estimated fair value. The marketable securities in the JP Morgan Invest Self-Directed Account, which include common stocks, mutual funds, bonds and a money market fund, are reported at fair value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. USE OF ESTIMATES The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. PLAN AMENDMENTS The Company has amended the Plan to maintain their favorable determination letter status from the IRS and to follow the provisions required by the GUST. These amendments do not have a material effect on net assets individually or in aggregate. The four amendments change the following: 1) It provides participants with an election to have allocated dividends with respect to vested ESOP shares and the Company stock fund shares paid to the participant or retained in the participant's account and add provisions relating to the allocation of dividends on non-vested shares, 2) The definition of Eligible Nonelective Contribution Employee is amended to include individuals who terminated employment on or after October 1, 2002, through December 31, 2006, due to the indefinite closure of an office location or elimination of the individual's position provided that the individual does not terminate employment prior to the date established by the employer, 3) Any participant whose position was eliminated beginning September 1, 2001 shall have a fully vested interest in their account balance upon their termination of employment provided this provision will not apply if the employee terminates employment prior to the termination date established by AmerUs, and 4) The Plan is amended to provide that a plan loan of a participant who is terminated by reason 9 All * AmerUs Savings and Retirement Plan Notes to Financial Statements (continued) 2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) of an office closure or the elimination of the participant's position will not be accelerated as long as at least quarterly repayments are made, provided that the participant does not terminate employment prior to the date established by the employer. 3. INVESTMENTS Participants have no investment direction authority over that portion the AmerUs common stock related to the non-vested ESOP Company core contributions. A summary of the significant components of the changes in the ESOP portion of the AmerUs common stock is as follows: YEAR ENDED DECEMBER 31 2004 2003 ------------ ------------- AmerUs Group Co. common stock, beginning of year $10,073,935 $ 8,329,883 Dividend income 108,901 114,386 Net unrealized and realized gains on investments 2,882,633 1,931,790 Employer contributions 1,569,152 1,385,968 Benefits paid to participants (1,740,688) (1,637,941) Net transfers to other investments (522,245) (50,151) ----------- ------------ AmerUs Group Co. common stock, end of year $12,371,688 $ 10,073,935 =========== ============ The fair values of individual investments that represent 5% or more of the Plan's net assets are as follows: DECEMBER 31 2004 2003 ----------- ----------- American Century Funds: Ultra Investors Fund $13,637,138 $12,344,034 International Growth Fund 6,669,703 5,868,553 Value Fund 12,331,474 11,612,023 Stable Asset Fund 20,082,889 21,370,523 Income & Growth Fund 16,705,994 14,687,247 Common stock of AmerUs Group Co. 18,345,603 14,436,914 10 All * AmerUs Savings and Retirement Plan Notes to Financial Statements (continued) 3. INVESTMENTS (CONTINUED) During the years ended December 31, 2004 and 2003, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated in fair value as follows: DECEMBER 31 2004 2003 ---------- ----------- Mutual funds $5,374,336 $12,551,235 Common stock 4,214,452 2,777,193 ---------- ----------- $9,588,788 $15,328,428 ========== =========== 4. RISKS AND UNCERTAINTIES The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets available for benefits. 5. INCOME TAX STATUS The Plan has received a determination letter from the Internal Revenue Service dated July 24, 2003, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to this issuance of the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan, as amended, is qualified and the related trust is tax exempt. The plan sponsor has indicated that it will take the necessary steps, if any, to maintain the Plan's qualified status. 11 Supplemental Schedule All * AmerUs Savings and Retirement Plan EIN - 42-1458424 Plan 102 Schedule H, Line 4(i) - Schedule of Assets (Held at End of Year) December 31, 2004 DESCRIPTION OF INVESTMENT, IDENTITY OF ISSUE, BORROWER, INCLUDING MATURITY DATE, RATE CURRENT LESSOR OR SIMILAR PARTY OF INTEREST, PAR OR MATURITY VALUE COST VALUE ------------------------------------------------- ---------------------------------- ---------- ----------- PARTICIPANT DIRECTED: American Century Funds*: Ultra Investors Fund 462,276 shares $ 13,637,138 Vista Investors Fund 69,740 shares 1,012,627 International Growth Fund 736,170 shares 6,669,703 Value Fund 1,668,670 shares 12,331,474 Strategic Allocation: Aggressive Fund 592,543 shares 4,568,506 Strategic Allocation: Moderate Fund 674,331 shares 4,565,219 Strategic Allocation: Conservative Fund 270,945 shares 1,514,582 Stable Asset Fund 20,082,889 shares 20,082,889 Income & Growth Fund 544,701 shares 16,705,994 Diversified Bond Fund 402,864 shares 4,117,273 Real Estate Fund 53,681 shares 1,328,602 Barclays Global Investors S&P 500 Stock Fund 25,940 shares 3,785,925 Royce Fund Low-Priced Stock 192,377 shares 2,949,135 Harbor International Fund 3,400 shares 144,579 Buffalo Small Cap Fund 51,976 shares 1,437,146 Common Stock: AmerUs Group Co.* - Core Investment Fund 131,875 shares 5,973,915 JP Morgan Invest Self-Directed Account 3,199,491 Participant loans receivable Loans to participants, 4.0% to 3,060,279 10.0% due through 2018 NONPARTICIPANT DIRECTED: Common stock: AmerUs Group Co.* - ESOP 272,688 shares $6,871,032 12,371,688 ========== ------------ Total investments $119,456,165 ============ *Indicates party in interest to the Plan.
