(1) Restoration method. The restoration method is a funding method that adapts the underlying funding method of section 412 in the case of certain plans that are or have been terminated and are later restored by the Pension Benefit Guaranty Corporation (PBGC). The normal operation of the funding standard account, and all other provisions of section 412 and the regulations thereunder, are unchanged except as provided in this § 1.412(c)(1)-3. Under the restoration method, the PBGC shall determine a restoration payment schedule, extending over no more than 30 years, that replaces all charges and credits to the funding standard account attributable to pre-restoration amortization bases. The restoration payment schedule is determined on the basis of an actuarial valuation of the accrued liability of the plan on the initial post-restoration valuation date less the actuarial value of the plan assets on that date. The initial post-restoration valuation date is the date of the valuation that falls in the first plan year beginning on or after the date of the restoration order.

(2) Applicability of restoration method. A plan must use the restoration method if, and only if—

(1) In general. The initial restoration amortization base is determined under the underlying funding method used by the plan. When the plan uses a spread gain funding method that does not maintain an unfunded liability, the plan must change either to an immediate gain method that directly calculates an accrued liability or to a spread gain method that maintains an unfunded liability. A plan may adopt any cost method that satisfies this requirement and that is acceptable under section 412 and the regulations thereunder, provided that the plan administrator follows the procedures established by the Commissioner for changes in funding methods. The initial restoration amortization base is determined using the valuation for the plan year in which the initial post-restoration valuation date falls. The initial restoration amortization base equals the accrued liability with respect to plan benefit liabilities returned by the PBGC less the value of the plan assets returned by the PBGC. The initial restoration amortization base replaces all prior amortization bases including those under section 412(b)(2) (B), (C), and (D) and under section 412(b)(3)(B). Any base resulting from a change in funding method, including a change required under this paragraph, is treated as a prior amortization base within the meaning of this paragraph (b). Any accumulated funding deficiency or credit balance in the funding standard account is set equal to zero when the initial restoration amortization base is established.

(2) Example. The following example illustrates the provisions of this paragraph (b):

(1) Certification requirement. When the PBGC establishes a restoration payment schedule, the Executive Director of the PBGC must certify to the PBGC's Board of Directors, and to the Internal Revenue Service, that the PBGC has reviewed the funding of the plan, the financial condition of the plan sponsor and its controlled group members, the payments required under the restoration payment schedule (taking into account the availability of deferrals authorized under paragraph (c)(4) of this section), and any other factor that the PBGC deems relevant, and, based on that review, determines that it is in the best interests of participants and beneficiaries of the plan and the pension insurance program that the restored plan not be reterminated.

(2) Requirements for restoration payment schedule—(i) Amortization of base over period of no more than 30 years. The restoration payment schedule must be prescribed in an order requiring the employer to make stated contributions to the plan sufficient to amortize the initial restoration amortization base over a period extending not more than 30 years after the initial post-restoration valuation date (the restoration payment period). Payments included in the restoration payment schedule order are charged to the funding standard account of the plan at the end of each plan year in accordance with paragraph (d) of this section. The restoration payment schedule must provide for total charges that are sufficient to amortize the entire amount of the initial restoration amortization base by the end of the restoration payment period. The scheduled charges need not be in level amounts, but the present value of the prescribed charges on the initial post-restoration valuation date, computed with interest at the valuation rate, must equal the initial restoration amortization base.

(3) Amendments to the restoration payment schedule. The order establishing the restoration payment schedule may be amended by the PBGC from time to time with respect to any remaining payments, provided that no amendment may extend the restoration payment period beyond 30 years from the initial post-restoration valuation date, and provided further that the restoration payment schedule, as amended, satisfies the requirements of paragraph (c)(2) of this section.

(4) Deferral of minimum scheduled annual payment amounts

(i) The unfunded section 412(l) restoration liability amount; plus

(ii) The unfunded new liability amount.

(2) Unfunded section 412(l) restoration liability amount. The unfunded section 412(l) restoration liability amount is the amount necessary to amortize fully the unfunded section 412(l) restoration liability in installments, as prescribed by the PBGC, over not more than 30 years. The annual amount need not be level, but at all times the present value of the future amortization charges prescribed under the restoration payment schedule, at the current liability interest rate, must equal the outstanding balance of the unfunded section 412(l) restoration liability and the schedule must provide that at the end of no more than 30 years the entire amount of the unfunded section 412(l) restoration liability base will have been fully amortized. The schedule prescribed for amortization of the unfunded section 412(l) restoration liability must comply with the requirements imposed in paragraph (c) of this section on the restoration payment schedule, except as provided in paragraph (g)(7) of this section and except that the maximum permitted outstanding balance of the unfunded section 412(l) restoration liability at the end of the tenth plan year must not be greater than the outstanding balance of the section 412(l) restoration liability that would have remained at the end of the tenth plan year if the unfunded section 412(l) restoration liability had been amortized in level amounts over the restoration payment period at the actual current liability interest rate for each year, increased by the current liability interest rate differential as defined under paragraph (g)(7) of this section. The unfunded section 412(l) restoration liability amount for the tenth plan year otherwise prescribed under the restoration payment schedule is increased by any outstanding current liability interest rate differential. By issuing an appropriate order, the PBGC may permit the outstanding current liability interest rate differential to be amortized over the tenth through the fourteenth plan years. If the PBGC permits the amortization of the outstanding current liability interest rate differential, then the unfunded section 412(l) restoration liability amount for each year to which an amortization payment is attributed under the order shall be increased by such payment. The outstanding balance otherwise required by paragraph (g)(2) of this section is increased by the outstanding balance, if any, of the base resulting from the amortization of the current liability interest rate differential. The PBGC may amend the amortization schedule for the unfunded section 412(l) restoration liability subject to the limits on amendments to the amortization schedule prescribed for the initial restoration amortization base.

(3) Establishment of unfunded section 412(l) restoration liability. In the plan year in which the initial post-restoration valuation date falls, the unfunded section 412(l) restoration liability is equal to the unfunded current liability of the plan.

(4) Unfunded new liability amount. In the case of a plan using the restoration method, the unfunded new liability amount is the applicable percentage, as defined in section 412(l)(4)(C), of the unfunded new liability determined under paragraph (g)(5) of this section.

(5) Unfunded new liability. The unfunded new liability of a plan using the restoration method is the excess, if any, of the unfunded current liability of the plan, within the meaning of section 412(l)(8)(A) for the plan year (determined without taking into account any unpredictable contingent event benefits, even if the event has occurred) over the outstanding balance of the unfunded section 412(l) restoration liability determined under paragraph (g)(3) of this section.

(6) Offset of amortization charges. The amounts charged to the funding standard account pursuant to the restoration payment schedule in order to amortize the initial restoration base, as described in paragraph (d) of this section, must be offset against the deficit reduction contribution in paragraph (g)(1) of this section along with any other applicable amounts provided in section 412(l)(1)(A)(ii).

(7) Interest rate differential. During the first 10 plan years after the initial post-restoration valuation date, the restoration payment schedule must prescribe an unfunded section 412(l) restoration liability amount for each plan year that is sufficient to prevent the outstanding balance of the unfunded section 412(l) restoration liability from exceeding the initial amount of the unfunded section 412(l) restoration liability increased by the current liability interest rate differential. The current liability interest rate differential at any point during the first ten years of the restoration payment period is the excess, if any, of the outstanding balance of the unfunded section 412(l) restoration liability determined using the actual current liability interest rate for each year, taking into account the charges described in paragraph (d) of this section, over the outstanding balance of the unfunded section 412(l) restoration liability determined using the lowest, for each year, of the initial current liability interest rate, the current liability interest rate for the computation year, and the valuation interest rate, taking into account the charges described in paragraph (d) of this section.
