CORRECTIONS OF MORTALITY TABLES.

SEC. 335. CORRECTIONS OF MORTALITY TABLES.(a) In General.—Not later than 18 months after the date of the enactment of this Act, the Secretary of the Treasury (or the Secretary’s delegate) shall amend the regulation relating to “Mortality Tables for Determining Present Value Under Defined Benefit Pension Plans” (82 Fed. Reg. 46388 (October 5, 2017)). Under such amendment, for valuation dates occurring during or after 2024, such mortality improvement rates shall not assume for years beyond the valuation date future mortality improvements at any age which are greater than .78 percent. The Secretary of the Treasury (or delegate) shall by regulation modify the .78 percent figure in the preceding sentence as necessary to reflect material changes in the overall rate of improvement projected by the Social Security Administration. (b) Effective Date.—The amendments required under subsection (a) shall be deemed to have been made as of the date of the enactment of this Act, and as of such date all applicable laws shall be applied in all respects as though the actions which the Secretary of the Treasury (or the Secretary’s delegate) is required to take under such subsection had been taken.136 STAT. 5373
