                         Report of Independent Auditors



The Administrative Committee
American Medical Security
Retirement Savings Plan

We have audited the accompanying statements of net assets available for benefits
of American Medical Security Retirement Savings Plan as of December 31, 2001 and
2000, 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 auditing standards generally accepted
in the 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, 2001 and 2000, and the changes in its net assets available for
benefits for the years then ended, in conformity with accounting principles
generally accepted in the United States.

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, 2001, 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.

                American Medical Security Retirement Savings Plan

                          Notes to Financial Statements

                                December 31, 2001



1. DESCRIPTION OF THE PLAN

The following description of the American Medical Security Retirement Savings
Plan (the Plan) provides only general information. Participants should refer to
the Plan document for a complete description of the Plan's provisions.

GENERAL

The Plan is a contributory defined contribution plan covering all full-time and
part-time employees of American Medical Security Group, Inc. (AMSG) and its
subsidiaries, American Medical Security, Inc. and Nurse Healthline, Inc.
(collectively the Company or Employer). The Plan is subject to the provisions of
the Employee Retirement Income Security Act of 1974 (ERISA).

PARTICIPATION AND VESTING

In 2001, employees are eligible to become contributing participants in the Plan
and receive matching contributions on the first of the following month after
reaching the age of eighteen and after 30 days of eligible service. Employees
with 30 days of service that are employed on the last day of the Plan year are
entitled to receive profit-sharing contributions for the Plan year. In 2000,
participants were eligible for Company profit-sharing contributions after six
months of service, and must have worked 1,000 hours in a Plan year to receive a
profit-sharing contribution.

Participants are immediately vested in their contributions plus actual earnings
thereon. New participants do not vest in Company contributions until three years
of service, at which time they become fully vested. Participants in the Plan
prior to January 1, 2000, vest in Company contributions according to the
following schedule (1,000 hours of service are required to constitute a year of
vesting service):

          Years of Vesting Service                 Vesting Percentage
     ----------------------------------        -------------------------
                     1                                        0%
                     2                                       30
                     3                                      100

                    Notes to Financial Statements (continued)




1. DESCRIPTION OF THE PLAN (CONTINUED)

The nonvested portion of the Company's profit sharing and matching contributions
are forfeited when a participant terminates employment. Profit-sharing
forfeitures are allocated to the remaining Plan participants, while matching
contribution forfeitures are used to reduce future matching contributions.
During 2001 and 2000, the Company utilized forfeited amounts of $133,000 and
$75,000, respectively, to offset the required matching contribution.

CONTRIBUTIONS, WITHDRAWALS AND LOANS

Plan participants are permitted to make contributions on a before-tax basis each
payroll period of 2% to 18% of base compensation, subject to the maximum amount
allowed by the Internal Revenue Code (IRC). Participants can change their
before-tax contribution percentage each quarter. Participants direct current
contributions and accumulated contributions and earnings between funds offered
through the Plan.

The Company contributes 60% of the first 6% of compensation that a participant
contributes to the Plan. Additional amounts may be contributed at the option of
the Company. Effective January 1, 2002, the Company has increased the matching
contribution formula from 60% to 70% of the first 6% of participants elective
deferrals.

The Company may make a yearly profit sharing contribution in an amount to be
determined each year.  During 2001 and 2000, the Company did not make profit
sharing contributions to the plan.

Distributions due to retirement, death, permanent disability and termination of
employment are provided for as defined within the Plan.

Participants may borrow from their fund accounts a minimum of $1,000 up to a
maximum of the lesser of one-half of their vested account balance or $50,000.
The loan is secured by the balance in the participant's account and bears
interest at a rate commensurate with prevailing rates as determined by the Plan
administrator. Principal and interest are repaid through payroll deductions.

1. DESCRIPTION OF THE PLAN (CONTINUED)

TERMINATION OF THE PLAN

The Company has established the Plan with the intention and expectation that the
Employer will be able to make contributions indefinitely, but the Employer
neither is, nor shall, be under any obligation or liability whatsoever to
maintain the Plan for any given length of time. The Company retains the right to
modify or terminate the Plan at any time, but may not retroactively reduce the
share of any participant or cause the Plan's assets to revert to the Company
unless required by law. In the event of termination, the balance of each
participant's account would become fully vested, and all assets would be
distributed to the participants and beneficiaries.

EXPENSES

Administrative expenses of the Plan are paid from Plan assets.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

INVESTMENT VALUATION AND ACCOUNTING METHOD

The Plan's financial statements are prepared on the accrual basis of accounting.
The Plan's investments are stated at fair value. The fair value of mutual fund
shares and AMSG common stock are based on the quoted market values on the last
business day of the Plan year. The fair value of the participation units in the
common trust fund is based on quoted redemption values. Participant loans are
stated at their unpaid principal balance, which approximates fair value.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires the Company to make estimates
that affect the amounts reported in the Plan's financial statements and
accompanying notes. Actual results could differ from these estimates.

                                               =================================

4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated January 28, 2002 stating that the Plan is qualified under Section 401(a)
of the IRC and, therefore, the related trust is exempt from taxation. Once
qualified, the Plan is required to operate in conformity with the IRC to
maintain its qualification. The Plan was amended subsequent to the IRS
determination letter. The Plan administrator believes the Plan is being operated
in compliance with the applicable requirements of the IRC and, therefore,
believes that the Plan is qualified and the related trust is tax exempt.

5. TRANSACTIONS WITH PARTIES IN INTEREST

Investment fees incurred are paid by participants. In addition, certain services
are provided by the Plan sponsor at no cost to the Plan.
