7.07 Age 70 1/2 Required Distribution
(a) A Participant who attains age 70 1/2 on or after January 1, 2000, shall begin his or her distribution of his or her Account Balance no later than the April 1st following the later of the calendar year in which he or she attains age 70 1/2 or the calendar year in which the Participant terminates employment. In accordance with the Worker, Retiree, and Employer Recovery Act of 2008, and newly published Code Section 401(a)(9)(H),the minimum required distribution may be waived temporarily for calendar year 2009.
(b) In the event a Participant in active service was required prior to January 1, 2000 to begin receiving payments while in service under the provisions of a Prior Plan, the Thrift Savings Plan shall distribute to the Participant in each distribution calendar year the minimum amount required to satisfy the provisions of Code Section 401(a)(9) provided; however, that the payment for the first distribution calendar year shall be made on or before April 1 of the following calendar year. Such minimum amount will be determined on the basis of the joint life expectancy of the Participant and his or her Beneficiary. Such life expectancy will be recalculated once each year; however, the life expectancy of the Beneficiary will not be recalculated if the Beneficiary is not the Participants spouse. The amount of the withdrawal shall be allocated among the Investment Funds in proportion to the value of the
Account Balance as of the date of each withdrawal. The commencement of payments under this Section shall not constitute an Annuity Starting Date for purposes of Code Sections 72, 401(a)(11) and 417. Upon the Participants subsequent termination of employment, payment of the Participants Account Balance shall be made in accordance with the provisions of Section 7.08.
(c) With respect to distributions under the Thrift Savings Plan made in calendar years beginning on or after January 1, 2000, the Thrift Savings Plan will apply the minimum distribution requirements of Code Section 401(a)(9) that were proposed in January 2001, notwithstanding any provision of the Thrift Savings Plan to the contrary. This amendment shall continue in effect until the end of the last calendar year beginning before the effective date of final regulations under Code Section 401(a)(9) or such other date specified in guidance published by the Internal Revenue Service. With respect to determining the amount of and the timing for required minimum distributions for calendar years on or after January 1, 2003, the Thrift Savings Plan will comply with the final regulations under Code Section 401(a)(9) as promulgated on June 15, 2004 and published in the Federal Register as 69 FR 33288 -01.
