§ 430. Minimum funding standards for single-employer defined benefit pension plans

(a) Minimum required contribution
For purposes of this section and section 412 (a)(2)(A), except as provided in subsection (f), the term “minimum required contribution” means, with respect to any plan year of a defined benefit plan which is not a multiemployer plan—
(1) in any case in which the value of plan assets of the plan (as reduced under subsection (f)(4)(B)) is less than the funding target of the plan for the plan year, the sum of—
(A) the target normal cost of the plan for the plan year,
(B) the shortfall amortization charge (if any) for the plan for the plan year determined under subsection (c), and
(C) the waiver amortization charge (if any) for the plan for the plan year as determined under subsection (e);
(2) in any case in which the value of plan assets of the plan (as reduced under subsection (f)(4)(B)) equals or exceeds the funding target of the plan for the plan year, the target normal cost of the plan for the plan year reduced (but not below zero) by such excess.
(b) Target normal cost
For purposes of this section:
(1) In general
Except as provided in subsection (i)(2) with respect to plans in at-risk status, the term “target normal cost” means, for any plan year, the excess of—
(A) the sum of—
(i) the present value of all benefits which are expected to accrue or to be earned under the plan during the plan year, plus
(ii) the amount of plan-related expenses expected to be paid from plan assets during the plan year, over
(B) the amount of mandatory employee contributions expected to be made during the plan year.
(2) Special rule for increase in compensation
For purposes of this subsection, if any benefit attributable to services performed in a preceding plan year is increased by reason of any increase in compensation during the current plan year, the increase in such benefit shall be treated as having accrued during the current plan year.
(c) Shortfall amortization charge
(1) In general
For purposes of this section, the shortfall amortization charge for a plan for any plan year is the aggregate total (not less than zero) of the shortfall amortization installments for such plan year with respect to any shortfall amortization base which has not been fully amortized under this subsection.
(2) Shortfall amortization installment
For purposes of paragraph (1)—
(A) Determination
The shortfall amortization installments are the amounts necessary to amortize the shortfall amortization base of the plan for any plan year in level annual installments over the 7-plan-year period beginning with such plan year.
(B) Shortfall installment
The shortfall amortization installment for any plan year in the 7-plan-year period under subparagraph (A) with respect to any shortfall amortization base is the annual installment determined under subparagraph (A) for that year for that base.
(C) Segment rates
In determining any shortfall amortization installment under this paragraph, the plan sponsor shall use the segment rates determined under subparagraph (C) of subsection (h)(2), applied under rules similar to the rules of subparagraph (B) of subsection (h)(2).
(D) Special election for eligible plan years
(i) In general If a plan sponsor elects to apply this subparagraph with respect to the shortfall amortization base of a plan for any eligible plan year (in this subparagraph and paragraph (7) referred to as an “election year”), then, notwithstanding subparagraphs (A) and (B)—
(I) the shortfall amortization installments with respect to such base shall be determined under clause (ii) or (iii), whichever is specified in the election, and
(II) the shortfall amortization installment for any plan year in the 9-plan-year period described in clause (ii) or the 15-plan-year period described in clause (iii), respectively, with respect to such shortfall amortization base is the annual installment determined under the applicable clause for that year for that base.
(ii) 2 plus 7 amortization schedule The shortfall amortization installments determined under this clause are—
(I) in the case of the first 2 plan years in the 9-plan-year period beginning with the election year, interest on the shortfall amortization base of the plan for the election year (determined using the effective interest rate for the plan for the election year), and
(II) in the case of the last 7 plan years in such 9-plan-year period, the amounts necessary to amortize the remaining balance of the shortfall amortization base of the plan for the election year in level annual installments over such last 7 plan years (using the segment rates under subparagraph (C) for the election year).
(iii) 15-year amortization The shortfall amortization installments determined under this subparagraph are the amounts necessary to amortize the shortfall amortization base of the plan for the election year in level annual installments over the 15-plan-year period beginning with the election year (using the segment rates under subparagraph (C) for the election year).
(iv) Election
(I) In general The plan sponsor of a plan may elect to have this subparagraph apply to not more than 2 eligible plan years with respect to the plan, except that in the case of a plan described in section 106 of the Pension Protection Act of 2006, the plan sponsor may only elect to have this subparagraph apply to a plan year beginning in 2011.
(II) Amortization schedule Such election shall specify whether the amortization schedule under clause (ii) or (iii) shall apply to an election year, except that if a plan sponsor elects to have this subparagraph apply to 2 eligible plan years, the plan sponsor must elect the same schedule for both years.
(III) Other rules Such election shall be made at such time, and in such form and manner, as shall be prescribed by the Secretary, and may be revoked only with the consent of the Secretary. The Secretary shall, before granting a revocation request, provide the Pension Benefit Guaranty Corporation an opportunity to comment on the conditions applicable to the treatment of any portion of the election year shortfall amortization base that remains unamortized as of the revocation date.
(v) Eligible plan year For purposes of this subparagraph, the term “eligible plan year” means any plan year beginning in 2008, 2009, 2010, or 2011, except that a plan year shall only be treated as an eligible plan year if the due date under subsection (j)(1) for the payment of the minimum required contribution for such plan year occurs on or after the date of the enactment of this subparagraph.
(vi) Reporting A plan sponsor of a plan who makes an election under clause (i) shall—
(I) give notice of the election to participants and beneficiaries of the plan, and
(II) inform the Pension Benefit Guaranty Corporation of such election in such form and manner as the Director of the Pension Benefit Guaranty Corporation may prescribe.
(vii) Increases in required installments in certain cases For increases in required contributions in cases of excess compensation or extraordinary dividends or stock redemptions, see paragraph (7).
(3) Shortfall amortization base
For purposes of this section, the shortfall amortization base of a plan for a plan year is—
(A) the funding shortfall of such plan for such plan year, minus
(B) the present value (determined using the segment rates determined under subparagraph (C) of subsection (h)(2), applied under rules similar to the rules of subparagraph (B) of subsection (h)(2)) of the aggregate total of the shortfall amortization installments and waiver amortization installments which have been determined for such plan year and any succeeding plan year with respect to the shortfall amortization bases and waiver amortization bases of the plan for any plan year preceding such plan year.
(4) Funding shortfall
For purposes of this section, the funding shortfall of a plan for any plan year is the excess (if any) of—
(A) the funding target of the plan for the plan year, over
(B) the value of plan assets of the plan (as reduced under subsection (f)(4)(B)) for the plan year which are held by the plan on the valuation date.
(5) Exemption from new shortfall amortization base
(A) In general
In any case in which the value of plan assets of the plan (as reduced under subsection (f)(4)(A)) is equal to or greater than the funding target of the plan for the plan year, the shortfall amortization base of the plan for such plan year shall be zero.
(B) Transition rule
(i) In general Except as provided in clause (iii), in the case of plan years beginning after 2007 and before 2011, only the applicable percentage of the funding target shall be taken into account under paragraph (3)(A) in determining the funding shortfall for purposes of paragraph (3)(A) and subparagraph (A).
(ii) Applicable percentage For purposes of subparagraph (A), the applicable percentage shall be determined in accordance with the following table:
    In the case of a plan year The applicable      beginning in calendar year: percentage is   2008 92     2009 94     2010 96.

(I) which was not in effect for a plan year beginning in 2007, or
(II) which was in effect for a plan year beginning in 2007 and which was subject to section 412 (l) (as in effect for plan years beginning in 2007) for such year, determined after the application of paragraphs (6) and (9) thereof.
(6) Early deemed amortization upon attainment of funding target
In any case in which the funding shortfall of a plan for a plan year is zero, for purposes of determining the shortfall amortization charge for such plan year and succeeding plan years, the shortfall amortization bases for all preceding plan years (and all shortfall amortization installments determined with respect to such bases) shall be reduced to zero.
(7) Increases in alternate required installments in cases of excess compensation or extraordinary dividends or stock redemptions
(A) In general
If there is an installment acceleration amount with respect to a plan for any plan year in the restriction period with respect to an election year under paragraph (2)(D), then the shortfall amortization installment otherwise determined and payable under such paragraph for such plan year shall, subject to the limitation under subparagraph (B), be increased by such amount.
(B) Total installments limited to shortfall base
Subject to rules prescribed by the Secretary, if a shortfall amortization installment with respect to any shortfall amortization base for an election year is required to be increased for any plan year under subparagraph (A)—
(i) such increase shall not result in the amount of such installment exceeding the present value of such installment and all succeeding installments with respect to such base (determined without regard to such increase but after application of clause (ii)), and
(ii) subsequent shortfall amortization installments with respect to such base shall, in reverse order of the otherwise required installments, be reduced to the extent necessary to limit the present value of such subsequent shortfall amortization installments (after application of this paragraph) to the present value of the remaining unamortized shortfall amortization base.
(C) Installment acceleration amount
For purposes of this paragraph—
(i) In general The term “installment acceleration amount” means, with respect to any plan year in a restriction period with respect to an election year, the sum of—
(I) the aggregate amount of excess employee compensation determined under subparagraph (D) with respect to all employees for the plan year, plus
(II) the aggregate amount of extraordinary dividends and redemptions determined under subparagraph (E) for the plan year.
(ii) Annual limitation The installment acceleration amount for any plan year shall not exceed the excess (if any) of—
(I) the sum of the shortfall amortization installments for the plan year and all preceding plan years in the amortization period elected under paragraph (2)(D) with respect to the shortfall amortization base with respect to an election year, determined without regard to paragraph (2)(D) and this paragraph, over
(II) the sum of the shortfall amortization installments for such plan year and all such preceding plan years, determined after application of paragraph (2)(D) (and in the case of any preceding plan year, after application of this paragraph).
(iii) Carryover of excess installment acceleration amounts
(I) In general If the installment acceleration amount for any plan year (determined without regard to clause (ii)) exceeds the limitation under clause (ii), then, subject to subclause (II), such excess shall be treated as an installment acceleration amount with respect to the succeeding plan year.
(II) Cap to apply If any amount treated as an installment acceleration amount under subclause (I) or this subclause with respect any succeeding plan year, when added to other installment acceleration amounts (determined without regard to clause (ii)) with respect to the plan year, exceeds the limitation under clause (ii), the portion of such amount representing such excess shall be treated as an installment acceleration amount with respect to the next succeeding plan year.
(III) Limitation on years to which amounts carried for No amount shall be carried under subclause (I) or (II) to a plan year which begins after the first plan year following the last plan year in the restriction period (or after the second plan year following such last plan year in the case of an election year with respect to which 15-year amortization was elected under paragraph (2)(D)).
(IV) Ordering rules For purposes of applying subclause (II), installment acceleration amounts for the plan year (determined without regard to any carryover under this clause) shall be applied first against the limitation under clause (ii) and then carryovers to such plan year shall be applied against such limitation on a first-in, first-out basis.

(II) $1,000,000.
(ii) Amounts set aside for nonqualified deferred compensation If during any calendar year assets are set aside or reserved (directly or indirectly) in a trust (or other arrangement as determined by the Secretary), or transferred to such a trust or other arrangement, by a plan sponsor for purposes of paying deferred compensation of an employee under a nonqualified deferred compensation plan (as defined in section 409A) of the plan sponsor, then, for purposes of clause (i), the amount of such assets shall be treated as remuneration of the employee includible in income for the calendar year unless such amount is otherwise includible in income for such year. An amount to which the preceding sentence applies shall not be taken into account under this paragraph for any subsequent calendar year.
(iii) Only remuneration for certain post-2009 services counted Remuneration shall be taken into account under clause (i) only to the extent attributable to services performed by the employee for the plan sponsor after February 28, 2010.

(vii) Indexing of amount In the case of any calendar year beginning after 2010, the dollar amount under clause (i)(II) shall be increased by an amount equal to—
(I) such dollar amount, multiplied by
(II) the cost-of-living adjustment determined under section 1 (f)(3) for the calendar year, determined by substituting “calendar year 2009” for “calendar year 1992” in subparagraph (B) thereof.
 If the amount of any increase under clause (i) is not a multiple of $1,000, such increase shall be rounded to the next lowest multiple of $1,000.
(E) Extraordinary dividends and redemptions

(i) In general For purposes of subsections (a), (c)(4)(B), and (d)(2)(A), the value of plan assets is deemed to be such amount, reduced by the amount of the prefunding balance and the funding standard carryover balance.
(ii) Special rule for certain binding agreements with PBGC For purposes of subsection (c)(4)(B), the value of plan assets shall not be deemed to be reduced for a plan year by the amount of the specified balance if, with respect to such balance, there is in effect for a plan year a binding written agreement with the Pension Benefit Guaranty Corporation which provides that such balance is not available to reduce the minimum required contribution for the plan year. For purposes of the preceding sentence, the term “specified balance” means the prefunding balance or the funding standard carryover balance, as the case may be.
(C) Availability of balances in plan year for crediting against minimum required contribution
For purposes of paragraph (3)(C)(i) of this subsection, the value of plan assets is deemed to be such amount, reduced by the amount of the prefunding balance.
(5) Election to reduce balance prior to determinations of value of plan assets and crediting against minimum required contribution
(A) In general
The plan sponsor may elect to reduce by any amount the balance of the prefunding balance and the funding standard carryover balance for any plan year (but not below zero). Such reduction shall be effective prior to any determination of the value of plan assets for such plan year under this section and application of the balance in reducing the minimum required contribution for such plan for such plan year pursuant to an election under paragraph (2).
(B) Coordination between prefunding balance and funding standard carryover balance

(I) the aggregate total of employer contributions to the plan for the preceding plan year, over—
(II) the minimum required contribution for such preceding plan year.
(ii) Adjustments for interest Any excess contributions under clause (i) shall be properly adjusted for interest accruing for the periods between the first day of the current plan year and the dates on which the excess contributions were made, determined by using the effective interest rate for the preceding plan year and by treating contributions as being first used to satisfy the minimum required contribution.
(iii) Certain contributions necessary to avoid benefit limitations disregarded The excess described in clause (i) with respect to any preceding plan year shall be reduced (but not below zero) by the amount of contributions an employer would be required to make under subsection (b), (c), or (e) of section 436 to avoid a benefit limitation which would otherwise be imposed under such paragraph for the preceding plan year. Any contribution which may be taken into account in satisfying the requirements of more than 1 of such paragraphs shall be taken into account only once for purposes of this clause.
(C) Decreases
The prefunding balance of a plan shall be decreased (but not below zero) by—

(ii) as of the time specified in paragraph (5)(A), any reduction in such balance elected under paragraph (5).
(8) Adjustments for investment experience
In determining the prefunding balance or the funding standard carryover balance of a plan as of the first day of the plan year, the plan sponsor shall, in accordance with regulations prescribed by the Secretary, adjust such balance to reflect the rate of return on plan assets for the preceding plan year. Notwithstanding subsection (g)(3), such rate of return shall be determined on the basis of fair market value and shall properly take into account, in accordance with such regulations, all contributions, distributions, and other plan payments made during such period.
(9) Elections
Elections under this subsection shall be made at such times, and in such form and manner, as shall be prescribed in regulations of the Secretary.
