(Sec. 3) Amends the Worker, Retiree, and Employer Recovery Act of 2008 to extend through plan years beginning during the period October 1, 2008-December 31, 2011, certain funding-based limits on benefit accruals for single-employer plans with severe funding shortfalls. Revises the adjusted funding target attainment percentage factor in such limits for that period.
Amends ERISA and the IRC with respect to the allowance of a one-time prohibited payment by a single-employer plan. Declares that, in the case of payments the annuity starting date for which occurs on or before December 31, 2011, payments under a Social Security leveling option shall be treated as not in excess of the monthly amount paid under a single life annuity (plus an amount not in excess of a Social Security supplement).
Permits a plan sponsor to elect to apply such treatment to payments whose annuity starting date occurs before January 1, 2011.
Repeals related existing requirements as if they had never been enacted.
(Sec. 4) Amends ERISA and the IRC, as amended by PACMBPRA, to revise the threshold date, under rules for special relief from minimum funding standards, for the period during which a solvent multiemployer plan may treat, as an item separate from other experience losses, to be amortized over 30 years, the portion of any experience loss or gain attributable to net investment losses incurred in either or both of certain plan years. Changes the identity of such plan years from the first two plan years ending after August 31, 2008, to the first two plan years ending after June 30, 2008.
