                         Report of Independent Auditors

To the Participants and Advisory Committee of the
DST Systems of California, Inc. 401(k) Retirement Plan

In our opinion, the accompanying statements of net assets available for
benefits and the related statements of changes in net assets available for
benefits present fairly, in all material respects, the net assets available for
benefits of the DST Systems of California, Inc. 401(k) Retirement Plan
(the "Plan") at December 31, 2002 and 2001, and the changes in net assets
available for benefits for the years then ended in conformity with accounting
principles generally accepted in the United States of America. 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 of these statements in accordance with auditing standards
generally accepted in the United States of America, which 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, 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.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental Schedule of Assets
(Held at End of Year) is presented for the purpose of additional analysis and
is not a required part of the basic 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 the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

Notes to Financial Statements
-------------------------------------------------------------------------------


1.        Description of the Plan

The DST Systems of California, Inc. 401(k) Retirement Plan (the "Plan") is a
contributory, defined contribution plan subject to the provisions of the
Employee Retirement Income Security Act of 1974 (ERISA). The following brief
description of the Plan is provided for general information purposes only.
Participants should refer to the Plan agreement for more complete information.

Sponsor
The Plan Sponsor is DST Systems of California, Inc. (formerly USCS
International, Inc.), a wholly-owned subsidiary of DST Systems, Inc. ("DST").
Certain of its subsidiaries and affiliates (the "Sponsor") participate in the
plan.

Trustee
The trustee of the Plan is UMB Bank, n.a. (the "Trustee"). Prior to April 1,
2001, the trustee was Connecticut General Life Insurance Company (CIGNA). The
Trustee holds and administers all assets of the Plan in accordance with the
provisions of the Plan agreement.

Administration of the Plan
An advisory committee (the "Advisory Committee"), which consists of members who
are selected by the Board of Directors of the Sponsor, has full power, authority
and responsibility to control and manage the operations and administration of
the Plan. All expenses of operating the Plan may be paid out of Plan assets,
except to the extent the Sponsor decides to pay these expenses. For the years
ended December 31, 2002 and 2001, the Sponsor paid Plan expenses of $98,610 and
$100,145, respectively.

Eligibility
All employees of the Sponsor who were employed prior to January 1, 2000 and who
were not members of a collective bargaining unit or nonresident aliens were
eligible to participate in the Plan on the Plan entry date. The Plan entry date
is the later of the first day of the month following the date the employee
commences service or the date the employee attains age 21. After December 31,
1999, no new participants were allowed into the Plan.

Contributions and Vesting
Effective January 1, 2001, all invested balances in the Plan were fully vested
and no further contributions are planned. Participant and Sponsor contributions
under the Plan after December 31, 1999 are made to the DST Systems, Inc. 401(k)
Profit Sharing Plan and are subject to its terms and conditions.

Participant accounts
Each participant's account was credited with the participant's contributions,
matching contributions, profit sharing contributions and rollover contributions.
Each participant's account is credited with an allocation of Plan earnings or
losses. Allocations of earnings or losses are based on account balances.
Discretionary contributions were allocated to participant accounts based on the
proportion which the participant's eligible compensation bore to the aggregate
eligible compensation of all participants for the year. The benefit to which a
participant is entitled is the benefit that can be provided from the
participant's account.

                                        4

value) or any number of the investment options as selected by the Advisory
Committee. The investment options contain different degrees of risks.
Participants should refer to the respective fund prospectus for a more complete
description of the investment objectives of each fund. The Advisory Committee
reserves the right to change the available investment options from time to time.

Participants may change their investment options daily.

Distribution of benefits
Benefit distributions generally will be made in the event of retirement, death,
disability, resignation or dismissal. A participant's normal retirement age is
59 1/2.

Balances not exceeding $5,000 will be automatically distributed upon termination
as a cash lump sum as soon as administratively practicable following termination
of employment. Balances exceeding $5,000 (excluding rollover contributions and
related earnings or losses) will be distributed upon participant election as
soon as administratively practicable but no later than April 1st of the Plan
year following the Plan year in which age 70 1/2 is attained. Such distributions
may be elected as a lump sum or paid in monthly, quarterly or annual
installments. Distributions shall be made in cash or, at the option of the

                                         5



Participant, in cash plus the number of whole shares of DST Common Stock
allocated to the Participant's account.

Unless the participant otherwise elects, distributions begin no later than the
60th day after the close of the Plan year in which a participant reaches normal
retirement age or celebrates their 10th anniversary as a Plan member (whichever
is later). Participants under the age of 62 with balances exceeding $5,000
(excluding rollover contributions and related earnings or losses) must consent
to any distribution.

Upon death, all sums credited to the participant's account will be paid to the
beneficiary or beneficiaries designated by the participant.

Distributions may also be made in the event of financial hardship of the
participant. Certain restrictions apply.

Participant loans
Participants may borrow the lesser of $50,000 or 50% of their vested accounts
(subject to certain Plan and Internal Revenue Service limitations). Generally,
loans must be repaid within five years. Loans bear a fixed rate of interest,
which is set at loan origination using the Prime rate as publicly announced by
the Trustee plus 1%.

Plan termination
The Sponsor believes the Plan will continue without interruption; however, it
reserves the right to terminate the Plan at any time subject to the provisions
of ERISA. In the event of Plan termination, participants will become fully
vested in any unvested balances from Sponsor contributions and their respective
account balances will be distributed in accordance with the Plan.

2.       Significant Accounting Policies

Basis of accounting
The accompanying financial statements are presented on the accrual basis of
accounting.

Use of estimates
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets,
liabilities and changes in net assets available for plan benefits. Actual
results could differ from those estimates.

Cash and cash equivalents
Short-term liquid investments with a maturity of three months or less are
considered cash equivalents. Due to the short-term nature of these investments,
carrying value approximates market value.

Investment valuation and security transactions
Investments are recorded at fair value. Investments in mutual funds and DST
Common Stock are valued at net asset value representing the value at which
shares of the fund may be purchased or redeemed. Unrealized gains and losses are
recognized in the year in which they occur. Loans are valued at the current
amount due from participants.

                                       6



Contributions
Contributions are recognized in the year to which they relate.

Accounting for obligations for benefit payments
The Plan does not record a liability relating to the obligations for benefit
payments. Distributions paid to participants in 2003 for withdrawals and
employees terminated during 2002 was $279,670. The amount paid in 2002 for
withdrawals and employees terminated during 2001 was $7,957.

The Plan's Form 5500 reflects the liability in the year of withdrawal or
termination.

Income tax status of the Plan
The Internal Revenue Service has determined and informed the Sponsor by a letter
dated August 2002, that the Plan is designed in accordance with applicable
sections of the Internal Revenue Code (the "IRC"). The Plan has been amended
since receiving the determination letter. However, the Advisory Committee and
the Plan's tax counsel believe that the Plan is designed and is currently being
operated in compliance with the applicable requirements of the IRC. Therefore,
no provision for income taxes has been included in the Plan's financial
statements.

3.       Plan Investments

benefits at year-end:
