§ 4281.1 Purpose and scope.

(a) General —

(1) Purpose. When a multiemployer plan terminates by mass withdrawal under section 4041A(a)(2) of ERISA, the plan's assets and benefits must be valued annually under section 4281(b) of ERISA, and plan benefits may have to be reduced or suspended to the extent provided in section 4281 (c) or (d). This part implements the provisions of section 4281 and provides rules for applying for financial assistance from the PBGC under section 4261 of ERISA. The plan valuation rules in this part also apply to the determination of reallocation liability under section 4219(c)(1)(D) of ERISA and subpart B of part 4219 of this chapter for multiemployer plans that undergo mass withdrawal (with or without termination).

(2) Scope. This part applies to multiemployer plans covered by title IV of ERISA that have terminated by mass withdrawal under section 4041A(a)(2) of ERISA (including plans created by partition pursuant to section 4233 of ERISA). Subpart B of this part also applies to covered multiemployer plans that have undergone mass withdrawal without terminating.

(b) Subpart B. Subpart B establishes rules for determining the value of multiemployer plan benefits and assets, including outstanding claims for withdrawal liability, for plans required to perform annual valuations under section 4281(b) of ERISA or allocate unfunded vested benefits under section 4219(c)(1)(D) of ERISA.

(c) Subpart C. Subpart C sets forth procedures under which the plan sponsor of a terminated plan shall amend the plan to reduce benefits subject to reduction in accordance with section 4281(c) of ERISA and § 4041A.24(b) of this chapter. Subpart C applies to a plan for which the annual valuation required by § 4041A.24(a) indicates that the value of nonforfeitable benefits under the plan exceeds the value of the plan's assets (including claims for withdrawal liability) if, at the end of the plan year for which that valuation was done, the plan provided any benefits subject to reduction. Benefit reductions required to be made under subpart C shall not apply to accrued benefits under plans or plan amendments adopted on or before March 26, 1980, or under collective bargaining agreements entered into on or before March 26, 1980.

(d) Subpart D. Subpart D sets forth the procedures under which the plan sponsor of an insolvent plan must suspend benefit payments and issue insolvency notices in accordance with section 4281(d) of ERISA and § 4041A.25 (c) and (d) of this chapter. Subpart D applies to a plan that has been amended under section 4281(c) of ERISA and subpart C of this part to eliminate all benefits subject to reduction and to a plan that provided no benefits subject to reduction as of the date on which the plan terminated.
