4211.32—Presumptive method for withdrawals after the initial plan year.
(a) General rule.
Under this section, the amount of unfunded vested benefits allocable to an employer that withdraws from a merged plan after the initial plan year is the sum (but not less than zero) of—
(1)
The employer's proportional share, if any, of the unamortized amount of the plan's initial plan year unfunded vested benefits, as determined under paragraph (b) of this section;
(2)
The employer's proportional share of the unamortized amount of the change in the plan's unfunded vested benefits for plan years ending after the initial plan year, as determined under paragraph (c) of this section; and
(3)
The employer's proportional share of the unamortized amounts of the reallocated unfunded vested benefits (if any) as determined under paragraph (d) of this section.
(b) Share of initial plan year unfunded vested benefits.
An employer's proportional share, if any, of the unamortized amount of the plan's initial plan year unfunded vested benefits is the sum of the employer's share of its prior plan's liabilities (determined under paragraph (b)(1) of this section) and the employer's share of the adjusted initial plan year unfunded vested benefits (determined under paragraph (b)(2) of this section), with such sum reduced by five percent of the original amount for each plan year subsequent to the initial year.
(1) Share of prior plan liabilities.
An employer's share of its prior plan's liabilities is the amount of unfunded vested benefits that would have been allocable to the employer if it had withdrawn on the first day of the initial plan year, determined as if each plan had remained a separate plan.
(2) Share of adjusted initial plan year unfunded vested benefits.
An employer's share of the adjusted initial plan year unfunded vested benefits equals the plan's initial plan year unfunded vested benefits, less the amount that would be determined under paragraph (b)(1) of this section for each employer that had not withdrawn as of the end of the initial plan year, multiplied by a fraction—
(ii)
The denominator of which is the sum of the amounts that would be determined under paragraph (b)(1) of this section for each employer that had not withdrawn as of the end of the initial plan year.
(c) Share of annual changes.
An employer's proportional share of the unamortized amount of the change in the plan's unfunded vested for the plan years ending after the end of the initial plan year is the sum of the employer's proportional shares (determined under paragraph (c)(2) of this section) of the unamortized amount of the change in unfunded vested benefits (determined under paragraph (c)(1) of this section) for each plan year in which the employer has an obligation to contribute under the plan ending after the initial plan year and before the plan year in which the employer withdraws.
(1) Change in plan's unfunded vested benefits.
The change in a plan's unfunded vested benefits for a plan year is the amount by which the unfunded vested benefits at the end of a plan year, less the value as of the end of such year of all outstanding claims for withdrawal liability that can reasonably be expected to be collected from employers that had withdrawn as of the end of the initial plan year, exceed the sum of the unamortized amount of the initial plan year unfunded vested benefits (determined under paragraph (c)(1)(i) of this section) and the unamortized amounts of the change in unfunded vested benefits for each plan year ending after the initial plan year and preceding the plan year for which the change is determined (determined under paragraph (c)(1)(ii) of this section).
(i) Unamortized amount of initial plan year unfunded vested benefits.
The unamortized amount of the initial plan year unfunded vested benefits is the amount of those benefits reduced by five percent of the original amount for each succeeding plan year.
(ii) Unamortized amount of the change.
The unamortized amount of the change in a plan's unfunded vested benefits with respect to a plan year is the change in unfunded vested benefits for the plan year, reduced by five percent of such change for each succeeding plan year.
(2) Employer's proportional share.
An employer's proportional share of the amount determined under paragraph (c)(1) of this section is computed by multiplying that amount by a fraction—
(i)
The numerator of which is the total amount required to be contributed under the plan (or under the employer's prior plan) by the employer for the plan year in which the change arose and the four preceding full plan years; and
(ii)
The denominator of which is the total amount contributed under the plan (or under employer's prior plan) for the plan year in which the change arose and the four preceding full plan years by all employers that had an obligation to contribute under the plan for the plan year in which such change arose, reduced by any amount contributed by an employer that withdrew from the plan in the year in which the change arose.
(d) Share of reallocated amounts.
An employer's proportional share of the unamortized amounts of the reallocated unfunded vested benefits, if any, is the sum of the employer's proportional shares (determined under paragraph (d)(2) of this section) of the unamortized amount of the reallocated unfunded vested benefits (determined under paragraph (d)(1) of this section) for each plan year ending before the plan year in which the employer withdrew from the plan.
(1) Unamortized amount of reallocated unfunded vested benefits.
The unamortized amount of the reallocated unfunded vested benefits with respect to a plan year is the sum of the amounts described in paragraphs (d)(1)(i), (d)(1)(ii), and (d)(1)(iii) of this section for the plan year, reduced by five percent of such sum for each succeeding plan year.
(i) Uncollectible amounts.
Amounts included as reallocable under this paragraph are those that the plan sponsor determines in that plan year to be uncollectible for reasons arising out of cases or proceedings under title 11, United States Code, or similar proceedings, with respect to an employer that withdrew after the close of the initial plan year.
(ii) Relief amounts.
Amounts included as reallocable under this paragraph are those that the plan sponsor determines in that plan year will not be assessed as a result of the operation of section 4209, 4219(c)(1)(B), or 4225 of ERISA with respect to an employer that withdrew after the close of the initial plan year.
(iii) Other amounts.
Amounts included as reallocable under this paragraph are those that the plan sponsor determines in that plan year to be uncollectible or unassessable for other reasons under standards not inconsistent with regulations prescribed by the PBGC.
(2) Employer's proportional share.
An employer's proportional share of the amount of the reallocated unfunded vested benefits with respect to a plan year is computed by multiplying the unamortized amount of the reallocated unfunded vested benefits (as of the end of the year preceding the plan year in which the employer withdraws) by the allocation fraction described in paragraph (c)(2) of this section for the same plan year.
