            Report of Independent Registered Public Accounting Firm

The Board of Trustees
All * AmerUs Savings and Retirement Plan

We have audited the accompanying statements of net assets available for benefits
of All * AmerUs Savings and Retirement Plan as of December 31, 2003 and 2002,
and the related statements of changes in net assets available for benefits for
the years then ended. 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 the 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. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as 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, 2003 and 2002, 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 made 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, 2003, is presented for the 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. This supplemental schedule has been subjected to the auditing
procedures applied in our audit 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.

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 his 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, 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
$12,000 in 2003 and $11,000 in 2002. The annual contribution to all retirement
benefit plans shall not exceed the lesser of $40,000 or 100% of the
participant's compensation, 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. 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, the participant is fully vested in the portion of the participant's
account attributable to employer matching contributions. After five years of
service, the participant is fully vested in the core contribution, profit
sharing contributions, and any interim benefit supplement.

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

                                                                               5

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

USE OF ESTIMATES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles require 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
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 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 during the period from September 1, 2001 to December 31, 2003 shall
have a fully vested interest in their account balance upon their termination of
employment provided that during the period beginning January 1, 2003 and ending
December 31, 2003 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 of an office closure or the elimination of the participant's position
will not be accelerated, provided that the participant does not terminate
employment prior to the date established by the employer.

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.
