EXHIBIT 10.6 DST SYSTEMS, INC. SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN (Amended and Restated as of May 14, 2002) ARTICLE I. GENERAL 1.1 Purpose. The purpose of this Supplemental Executive Retirement Plan ("SERP") is to supplement the DST Systems, Inc. 401(k) Profit Sharing Plan and its predecessor plans (collectively called the "401(k) Plan"), and The Employee Stock Ownership Plan and Trust Agreement of DST Systems, Inc. (the "ESOP"). The 401(k) Plan and the ESOP are collectively referred to herein as the "Qualified Plan." The SERP is intended to generally replace lost benefits under the Qualified Plan due to limitations applicable to plans of that nature under the Internal Revenue Code of 1986, as amended (the "Code"). 1.2 Nature of SERP. The SERP is, and shall be administered as, an employee pension plan benefiting a select group of management or highly compensated employees under the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). The SERP shall be "unfunded" for tax purposes and for purposes of Title I of ERISA. Any and all payments under the SERP shall be made solely from the general assets of DST Systems, Inc. ("DST"). A Participant's interests under the SERP do not represent or create a claim against specific assets of DST or any Affiliated Company. Nothing herein shall be deemed to create a trust of any kind or create any fiduciary relationship between DST or its Board of Directors, any Affiliated Company, the Committee or its delegates, and a Participant, a Beneficiary or any other person or entity claiming for or through a Participant or Beneficiary. To the extent any person acquires a right to receive payments from DST under this SERP, such right is no greater than the right of any other unsecured general creditor of DST. ARTICLE II. DEFINITIONS Except as expressly provided herein, capitalized terms used in the SERP shall have the same meanings as set forth in the 401(k) Plan, and the 401(k) Plan's definitions and operative terms are incorporated herein by reference. In the event of a conflict between the meaning of the terms used in the SERP and the meaning of terms used in the 401(k) Plan, the meaning as set forth in the SERP shall prevail. 2.1 "Account" means the bookkeeping account established by the Committee or its delegate to reflect allocations made on behalf of a Participant and credited earnings, gains or losses thereon. 2.2 "Beneficiary" means the primary and contingent beneficiaries designated by a Participant by written instrument delivered to the Committee or its designee to receive any benefits payable hereunder following the Participant's death. A Participant may designate the proportions in which such beneficiaries are to receive such payments and may change such designation from time to time. The last written designation filed with the Committee or its designee prior to the Participant's death shall control. In the event no beneficiary is designated, or if the designated beneficiary predeceases the Participant, "Beneficiary" shall mean first the Participant's surviving spouse, then the Participant's known natural or adopted surviving children in equal amounts or, if there are no such surviving spouse or children, the Participant's estate. 2.3 "Committee" means the Compensation Committee of the DST Board of Directors. 2.4 "Compensation" means the Participant's base salary actually paid during a specified Plan Year, plus the value of accrued cash bonuses for such year. Solely for the 1999 Plan Year, "Compensation" shall also include the dollar value of restricted stock granted to such Participant for 1999 under the DST Systems, Inc. Officers Incentive Plan. 2.5 "Effective Date" means January 1, 1999, the first day of the first Plan Year for which this SERP is effective. 2.6 "Key Employee" means an employee of DST or an Affiliated Company who is in a select group of management or highly compensated employees. 2.7 "Participant" means any individual who is designated as a participant by the Committee pursuant to Section 3.2 and whose benefits under the SERP have not been fully distributed. 2.8 "Retirement" means a Termination of Employment by a Participant after attaining Normal Retirement Age, or such other Termination of Employment as determined by the Committee or its delegate from time to time . 2.9 "Valuation Date" means each March 31, June 30, September 30 and December 31 or such other dates as determined by the Committee in its sole discretion. ARTICLE III. PARTICIPATION 3.1 Eligibility. The following Key Employees shall be eligible to participate in the SERP: (a) For the 1999 Plan Year, Key Employees of DST and any Affiliated Company (other than USCS International, Inc. and its subsidiaries); and (b) For subsequent Plan Years, Key Employees of DST and its Affiliated Companies, including Key Employees of USCS International, Inc. and its subsidiaries, other than any Key Employee who is a participant in a nonqualified deferred compensation plan sponsored by such Affiliated Company. -2- 3.2 Participation. An eligible individual under Section 3.1 shall become a Participant in the SERP for a Plan Year for which such individual is designated by the Committee or its delegate to receive an allocation credit for such Plan Year. Once an eligible individual is designated by the Committee to receive any allocation credit for such Plan Year, such individual shall continue to receive an allocation credit for following Plan Years unless he or she ceases to be a Key Employee or the Committee otherwise provides. Once amounts are credited to an individual's Account under Article IV, such individual shall remain a Participant until his or her Account is distributed in full in accordance with Article V. Notwithstanding anything in this Section 3.2 to the contrary, in order for the Participant's Account to be credited with an allocation for a Plan Year, the Participant must satisfy the requirements of Section 4.3 for such Plan Year. ARTICLE IV. SERP ACCOUNTS AND CREDITS 4.1 Establishment of SERP Accounts. The Committee or its delegate shall establish an Account on behalf of each Participant. The amounts specified in Sections 4.4 and 4.5 shall be credited to the Participant's Account. 4.2 Nature of SERP Accounts. A Participant's Account shall be used solely as a measuring device to determine the amount (if any) to be paid a Participant under this SERP. No amounts shall actually be set aside with respect to any Account. All amounts at any time attributable to an Account shall be, and remain, the sole property of DST. A Participant's rights hereunder are limited to the right to receive SERP benefits as provided herein. An Account represents an unsecured promise by DST to pay the benefits provided by the SERP. 4.3 Allocation Requirements. To receive an allocation pursuant to Section 4.4 for a Plan Year, a Participant must satisfy each of the following requirements: (a) The Participant must have Compensation of at least the threshold amount. The threshold amount for 1999 is $170,000. For all subsequent Plan Years, the threshold amount is equal to the annual compensation limit in effect for the Plan Year under Code Section 401(a)(17). Notwithstanding Section 2.4 to the contrary, in determining if the threshold amount is satisfied, the dollar value of the equity portion of awards granted to a Participant for any Plan Year under the DST Systems, Inc. Officers Incentive Plan shall always be disregarded in determining Compensation for purposes of this Section 4.3(a); (b) The Participant must be employed by DST or an Affiliated Company on the last day of such Plan Year; -3- (c) The Participant must be credited with a Year of Service during such Plan Year; and (d) The Participant must be designated by the Committee, as provided in Section 3.2, as eligible to participate in any allocation credit for such year. 4.4 Allocation Credits. With respect to each Participant who has satisfied the requirements of Section 4.3 for a Plan Year, the Committee or its delegate shall credit for such Plan Year to such Participant's Account, as of March 31 next following the end of such Plan Year, the sum of the following amounts: (a) a percentage of Compensation, as defined for this purpose under the Qualified Plan, determined in the sole discretion of the Committee to generally approximate the percentage of employer contributions and forfeitures allocated under the Qualified Plan for the Plan Year, multiplied by the Participant's Compensation hereunder for the Plan Year in excess of the limit specified in Section 4.3(a); and (b) an additional percentage, if any, determined in the sole discretion of the Committee, multiplied by the Participant's Compensation for such Plan Year. Notwithstanding anything to the contrary, the allocation credit under this Section 4.4 shall be at the discretion of the Committee. For a Plan Year, the Committee may determine a zero percentage (0%) allocation credit under (a) and/or (b) above. The formula of (a) above shall not be construed as an obligation to exactly match the applicable percentage under the Qualified Plan. 4.5 Income, Gain or Loss Adjustment on SERP Accounts. As of each Valuation Date, the Committee or its delegate shall also adjust each Account to reflect the income, gain or loss that would have been earned on the Account had such amounts been invested since the preceding Valuation Date in one or more investment vehicles as selected by the Committee or its delegate prior to the applicable valuation period. The investment vehicle(s) may be indexed or other mutual funds, but in no event shall the investment vehicle be common stock of DST. 4.6 Participant Election. (a) A Participant may elect on a written election form to have his or her account adjusted on the basis that amounts in the Participant's account had been invested since the effective date of the Participant's latest dated written election in any of the investment vehicles designated by the Committee or its delegate, in such proportion as the Participant has designated on the written election form. -4- (b) A Participant may change such election annually, to be effective March 31, by written notice to DST's Corporate Secretary no later than ten days prior to March 31. (c) Any election made pursuant to this Section 4.6 shall remain in effect until changed by the Participant as provided in Section 4.6 (b). If the Participant makes no election pursuant to this Section 4.6, makes an election with respect to only a part of the Participant's Account, or terminates an election, then all portions of the Account not subject to an election pursuant to this Section 4.6 shall be credited with interest based on at the announced rate of return on an investment or investments selected from time to time by this Committee or its delegate. Subsequent to the Participant's Termination of Employment, the Participant may change an election pursuant to this Section 4.6 with respect to amounts that are not yet distributed pursuant to Section 5.3. ARTICLE V. SERP BENEFITS 5.1 No In-Service Distributions. Benefits hereunder shall not be payable to a Participant prior to the Participant's Termination of Employment. 5.2 Benefits Upon Termination of Employment (Other Than Retirement). Upon a Participant's Termination of Employment (for any reason other than Retirement), the vested portion of the Participant's SERP benefits shall be distributed to the Participant in a lump sum cash payment as soon as administratively practicable after the Valuation Date coinciding with or immediately following such Termination of Employment. The amount to be distributed to a Participant pursuant to this Section 5.2 shall be the value of the vested portion of the Participant's Account as of the Valuation Date coinciding with or immediately following the Participant's Termination of Employment. 5.3 Benefits Upon Retirement. Upon a Participant's Retirement, the Participant's SERP benefits shall be distributed to the Participant in a lump sum cash payment or in substantially equal annual cash installments over a fixed period not to exceed such period established by the Committee or its delegate, as elected by the Participant in accordance with Section 5.5. (a) If lump sum distribution is elected by the Participant or if no installment election is given effect under Section 5.5, the amount to be distributed shall be the value of the Participant's Account as of the Valuation Date immediately following the Participant's Retirement and such distribution shall be made as soon as administratively practicable after the Valuation Date coinciding with or immediately following such Retirement. -5- (b) If installments are elected by the Participant, the first annual installment shall be made as soon as administratively practicable following December 31 of the Plan Year in which the Participant's Retirement occurs, and as soon as administratively practicable following each succeeding December 31 until the Participant's Account is distributed in full. The amount of the first installment payment shall equal the value of the Participant's Account as of the December 31 of the Plan Year in which the Participant's Retirement occurs, divided by the total number of annual installment payments to be made. The amount of each succeeding installment payment shall equal the value of the vested portion of the Participant's Account as of the December 31 immediately preceding such payment, divided by the total number of annual installment payments remaining to be made (including the installment being calculated). 5.4 Benefits Upon Death. If the Participant dies prior to full payment of his or her SERP benefits under Section 5.2 or 5.3 above, the Participant's SERP benefits shall be paid to the Participant's Beneficiary in a lump sum cash payment as soon as administratively practicable after the Valuation Date coinciding with or immediately following the Participant's death. 5.5 Form Election. If a Participant's Termination of Employment is due to Retirement, distribution may be made under Section 5.3 in substantially equal cash installments over a fixed period not to exceed ten (10) years. A Participant may file a distribution election with the Committee on forms prescribed by the Committee. A distribution election, once given effect under this Section 5.5, will apply to the Participant's total benefits. To be given effect under this Section 5.5, any distribution election for benefits payable under Section 5.3 must have been filed with the Committee at least six (6) months before the Participant's Retirement. If a Participant's distribution election has not been on file with the Committee for the full six (6)-month period, it will not be recognized or given effect by the Committee. In that event, distribution shall be made in accordance with the Participant's most recent distribution election which was filed with the Committee at least six (6) months before the Participant's Retirement. ARTICLE VI. VESTING AND FORFEITURE 6.1 Vesting. A Participant's right to amounts allocated to his Account pursuant to Article IV shall become nonforfeitable based on such Participant's credited Years of Service from the Effective Date of the Plan in accordance with the following schedule: Years of Service Percentage Vested ---------------- ----------------- Less than 5 0% 5 or more 100% -6- Notwithstanding the above, a Participant shall become fully vested in his or her Account upon his or her Retirement, death, Disability, or upon a "Change of Control" of DST, as the phrase "Change of Control" is defined under the DST Systems, Inc. 1995 Stock Option and Performance Award Plan, as may be amended or restated from time to time. 6.2 Application of Forfeitures.
