(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.
(iii) Transition relief not available for new or deficit reduction plans Clause (i) shall not apply to a plan—
(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.

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.

For purposes of this paragraph—
(i) In general The term “excess employee compensation” means, with respect to any employee for any plan year, the excess (if any) of—
(I) the aggregate amount includible in income under this chapter for remuneration during the calendar year in which such plan year begins for services performed by the employee for the plan sponsor (whether or not performed during such calendar year), over
(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

(A) the value of plan assets for the plan year (as reduced under subsection (f)(4)(B)), bears to
(B) the funding target of the plan for the plan year (determined without regard to subsection (i)(1)).
(e) Waiver amortization charge
(1) Determination of waiver amortization charge
The waiver amortization charge (if any) for a plan for any plan year is the aggregate total of the waiver amortization installments for such plan year with respect to the waiver amortization bases for each of the 5 preceding plan years.

(II) had a positive balance in the funding standard account under section 412 (b) as in effect for such plan year and determined as of the end of such plan year.
(2) Application of balances
A prefunding balance and a funding standard carryover balance maintained pursuant to this paragraph—
(A) shall be available for crediting against the minimum required contribution, pursuant to an election under paragraph (3),

(4) Effect of balances on amounts treated as value of plan assets
In the case of any plan maintaining a prefunding balance or a funding standard carryover balance pursuant to this subsection, the amount treated as the value of plan assets shall be deemed to be such amount, reduced as provided in the following subparagraphs:
(A) Applicability of shortfall amortization base
For purposes of subsection (c)(5), the value of plan assets is deemed to be such amount, reduced by the amount of the prefunding balance, but only if an election under paragraph (3) applying any portion of the prefunding balance in reducing the minimum required contribution is in effect for the plan year.
(B) Determination of excess assets, funding shortfall, and funding target attainment percentage
(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
To the extent that any plan has a funding standard carryover balance greater than zero, no election may be made under subparagraph (A) with respect to the prefunding balance.
(6) Prefunding balance
(A) In general
A prefunding balance maintained by a plan shall consist of a beginning balance of zero, increased and decreased to the extent provided in subparagraphs (B) and (C), and adjusted further as provided in paragraph (8).
(B) Increases
(i) In general As of the first day of each plan year beginning after 2008, the prefunding balance of a plan shall be increased by the amount elected by the plan sponsor for the plan year. Such amount shall not exceed the excess (if any) of—
(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) ofsection 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—
(i) as of the first day of each plan year after 2008, the amount of such balance credited under paragraph (2) (if any) in reducing the minimum required contribution of the plan for the preceding plan year, and

(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.
(g) Valuation of plan assets and liabilities

For purposes of this subparagraph, all defined benefit plans (other than multiemployer plans) maintained by the same employer (or any member of such employer’s controlled group) shall be treated as 1 plan, but only participants with respect to such employer or member shall be taken into account.
(C) Application of certain rules in determination of plan size
For purposes of this paragraph—
(i) Plans not in existence in preceding year In the case of the first plan year of any plan, subparagraph (B) shall apply to such plan by taking into account the number of participants that the plan is reasonably expected to have on days during such first plan year.

(3) Determination of value of plan assets
For purposes of this section—
(A) In general
Except as provided in subparagraph (B), the value of plan assets shall be the fair market value of the assets.
(B) Averaging allowed
A plan may determine the value of plan assets on the basis of the averaging of fair market values, but only if such method—
(i) is permitted under regulations prescribed by the Secretary,
(ii) does not provide for averaging of such values over more than the period beginning on the last day of the 25th month preceding the month in which the valuation date occurs and ending on the valuation date (or a similar period in the case of a valuation date which is not the 1st day of a month), and
(iii) does not result in a determination of the value of plan assets which, at any time, is lower than 90 percent or greater than 110 percent of the fair market value of such assets at such time.
Any such averaging shall be adjusted for contributions, distributions, and expected earnings (as determined by the plan’s actuary on the basis of an assumed earnings rate specified by the actuary but not in excess of the third segment rate applicable under subsection (h)(2)(C)(iii)), as specified by the Secretary.
(4) Accounting for contribution receipts
For purposes of determining the value of assets under paragraph (3)—
(A) Prior year contributions
If—
(i) an employer makes any contribution to the plan after the valuation date for the plan year in which the contribution is made, and
(ii) the contribution is for a preceding plan year,
the contribution shall be taken into account as an asset of the plan as of the valuation date, except that in the case of any plan year beginning after 2008, only the present value (determined as of the valuation date) of such contribution may be taken into account. For purposes of the preceding sentence, present value shall be determined using the effective interest rate for the preceding plan year to which the contribution is properly allocable.
(B) Special rule for current year contributions made before valuation date
If any contributions for any plan year are made to or under the plan during the plan year but before the valuation date for the plan year, the assets of the plan as of the valuation date shall not include—
(i) such contributions, and
(ii) interest on such contributions for the period between the date of the contributions and the valuation date, determined by using the effective interest rate for the plan year.
(h) Actuarial assumptions and methods
(1) In general
Subject to this subsection, the determination of any present value or other computation under this section shall be made on the basis of actuarial assumptions and methods—
(A) each of which is reasonable (taking into account the experience of the plan and reasonable expectations), and
(B) which, in combination, offer the actuary’s best estimate of anticipated experience under the plan.
(2) Interest rates
(A) Effective interest rate
For purposes of this section, the term “effective interest rate” means, with respect to any plan for any plan year, the single rate of interest which, if used to determine the present value of the plan’s accrued or earned benefits referred to in subsection (d)(1), would result in an amount equal to the funding target of the plan for such plan year.
(B) Interest rates for determining funding target
For purposes of determining the funding target and target normal cost of a plan for any plan year, the interest rate used in determining the present value of the benefits of the plan shall be—
(i) in the case of benefits reasonably determined to be payable during the 5-year period beginning on the first day of the plan year, the first segment rate with respect to the applicable month,
(ii) in the case of benefits reasonably determined to be payable during the 15-year period beginning at the end of the period described in clause (i), the second segment rate with respect to the applicable month, and
(iii) in the case of benefits reasonably determined to be payable after the period described in clause (ii), the third segment rate with respect to the applicable month.
(C) Segment rates
For purposes of this paragraph—
(i) First segment rate The term “first segment rate” means, with respect to any month, the single rate of interest which shall be determined by the Secretary for such month on the basis of the corporate bond yield curve for such month, taking into account only that portion of such yield curve which is based on bonds maturing during the 5-year period commencing with such month.
(ii) Second segment rate The term “second segment rate” means, with respect to any month, the single rate of interest which shall be determined by the Secretary for such month on the basis of the corporate bond yield curve for such month, taking into account only that portion of such yield curve which is based on bonds maturing during the 15-year period beginning at the end of the period described in clause (i).
(iii) Third segment rate The term “third segment rate” means, with respect to any month, the single rate of interest which shall be determined by the Secretary for such month on the basis of the corporate bond yield curve for such month, taking into account only that portion of such yield curve which is based on bonds maturing during periods beginning after the period described in clause (ii).
(iv) Segment rate stabilization
(I) In general If a segment rate described in clause (i), (ii), or (iii) with respect to any applicable month (determined without regard to this clause) is less than the applicable minimum percentage, or more than the applicable maximum percentage, of the average of the segment rates described in such clause for years in the 25-year period ending with September 30 of the calendar year preceding the calendar year in which the plan year begins, then the segment rate described in such clause with respect to the applicable month shall be equal to the applicable minimum percentage or the applicable maximum percentage of such average, whichever is closest. The Secretary shall determine such average on an annual basis and may prescribe equivalent rates for years in any such 25-year period for which the rates described in any such clause are not available.
(II) Applicable minimum percentage; applicable maximum percentage For purposes of subclause (I), the applicable minimum percentage and the applicable maximum percentage for a plan year beginning in a calendar year shall be determined in accordance with the following table:

(D) Corporate bond yield curve
For purposes of this paragraph—
(i) In general The term “corporate bond yield curve” means, with respect to any month, a yield curve which is prescribed by the Secretary for such month and which reflects the average, for the 24-month period ending with the month preceding such month, of monthly yields on investment grade corporate bonds with varying maturities and that are in the top 3 quality levels available.
(ii) Election to use yield curve Solely for purposes of determining the minimum required contribution under this section, the plan sponsor may, in lieu of the segment rates determined under subparagraph (C), elect to use interest rates under the corporate bond yield curve. For purposes of the preceding sentence such curve shall be determined without regard to the 24-month averaging described in clause (i). Such election, once made, may be revoked only with the consent of the Secretary.
(E) Applicable month
For purposes of this paragraph, the term “applicable month” means, with respect to any plan for any plan year, the month which includes the valuation date of such plan for such plan year or, at the election of the plan sponsor, any of the 4 months which precede such month. Any election made under this subparagraph shall apply to the plan year for which the election is made and all succeeding plan years, unless the election is revoked with the consent of the Secretary.
(F) Publication requirements
The Secretary shall publish for each month the corporate bond yield curve (and the corporate bond yield curve reflecting the modification described in section 417 (e)(3)(D)(i) for such month) and each of the rates determined under subparagraph (C) and the averages determined under subparagraph (C)(iv) for such month. The Secretary shall also publish a description of the methodology used to determine such yield curve and such rates which is sufficiently detailed to enable plans to make reasonable projections regarding the yield curve and such rates for future months based on the plan’s projection of future interest rates.
(G) Transition rule
(i) In general Notwithstanding the preceding provisions of this paragraph, for plan years beginning in 2008 or 2009, the first, second, or third segment rate for a plan with respect to any month shall be equal to the sum of—

(II) the product of the rate determined under the rules of section 412 (b)(5)(B)(ii)(II) (as in effect for plan years beginning in 2007), multiplied by a percentage equal to 100 percent minus the applicable percentage.
(ii) Applicable percentage For purposes of clause (i), the applicable percentage is 331/3 percent for plan years beginning in 2008 and 662/3 percent for plan years beginning in 2009.
(iii) New plans ineligible Clause (i) shall not apply to any plan if the first plan year of the plan begins after December 31, 2007.
(iv) Election The plan sponsor may elect not to have this subparagraph apply. Such election, once made, may be revoked only with the consent of the Secretary.

(A) In general
Except as provided in subparagraph (C) or (D), the Secretary shall by regulation prescribe mortality tables to be used in determining any present value or making any computation under this section. Such tables shall be based on the actual experience of pension plans and projected trends in such experience. In prescribing such tables, the Secretary shall take into account results of available independent studies of mortality of individuals covered by pension plans.
(B) Periodic revision
The Secretary shall (at least every 10 years) make revisions in any table in effect under subparagraph (A) to reflect the actual experience of pension plans and projected trends in such experience.
(C) Substitute mortality table

(ii) Early termination of period Notwithstanding clause (i), a mortality table described in clause (i) shall cease to be in effect as of the earliest of—
(I) the date on which there is a significant change in the participants in the plan by reason of a plan spinoff or merger or otherwise, or
(II) the date on which the plan actuary determines that such table does not meet the requirements of clause (iii).
(iii) Requirements A mortality table meets the requirements of this clause if—
(I) there is a sufficient number of plan participants, and the pension plans have been maintained for a sufficient period of time, to have credible information necessary for purposes of subclause (II), and
(II) such table reflects the actual experience of the pension plans maintained by the sponsor and projected trends in general mortality experience.
(iv) All plans in controlled group must use separate table Except as provided by the Secretary, a plan sponsor may not use a mortality table under this subparagraph for any plan maintained by the plan sponsor unless—
(I) a separate mortality table is established and used under this subparagraph for each other plan maintained by the plan sponsor and if the plan sponsor is a member of a controlled group, each member of the controlled group, and
(II) the requirements of clause (iii) are met separately with respect to the table so established for each such plan, determined by only taking into account the participants of such plan, the time such plan has been in existence, and the actual experience of such plan.
(v) Deadline for submission and disposition of application
(I) Submission The plan sponsor shall submit a mortality table to the Secretary for approval under this subparagraph at least 7 months before the 1st day of the period described in clause (i).
(II) Disposition Any mortality table submitted to the Secretary for approval under this subparagraph shall be treated as in effect as of the 1st day of the period described in clause (i) unless the Secretary, during the 180-day period beginning on the date of such submission, disapproves of such table and provides the reasons that such table fails to meet the requirements of clause (iii). The 180-day period shall be extended upon mutual agreement of the Secretary and the plan sponsor.
(D) Separate mortality tables for the disabled
Notwithstanding subparagraph (A)—
(i) In general The Secretary shall establish mortality tables which may be used (in lieu of the tables under subparagraph (A)) under this subsection for individuals who are entitled to benefits under the plan on account of disability. The Secretary shall establish separate tables for individuals whose disabilities occur in plan years beginning before January 1, 1995, and for individuals whose disabilities occur in plan years beginning on or after such date.

(4) Probability of benefit payments in the form of lump sums or other optional forms
For purposes of determining any present value or making any computation under this section, there shall be taken into account—
(A) the probability that future benefit payments under the plan will be made in the form of optional forms of benefits provided under the plan (including lump sum distributions, determined on the basis of the plan’s experience and other related assumptions), and
(B) any difference in the present value of such future benefit payments resulting from the use of actuarial assumptions, in determining benefit payments in any such optional form of benefits, which are different from those specified in this subsection.
(5) Approval of large changes in actuarial assumptions
(A) In general
No actuarial assumption used to determine the funding target for a plan to which this paragraph applies may be changed without the approval of the Secretary.

(i) the plan is a defined benefit plan (other than a multiemployer plan) to which title IV of the Employee Retirement Income Security Act of 1974 applies,
(ii) the aggregate unfunded vested benefits as of the close of the preceding plan year (as determined under section 4006(a)(3)(E)(iii) of the Employee Retirement Income Security Act of 1974) of such plan and all other plans maintained by the contributing sponsors (as defined in section 4001(a)(13) of such Act) and members of such sponsors’ controlled groups (as defined in section 4001(a)(14) of such Act) which are covered by title IV (disregarding plans with no unfunded vested benefits) exceed $50,000,000, and
(iii) the change in assumptions (determined after taking into account any changes in interest rate and mortality table) results in a decrease in the funding shortfall of the plan for the current plan year that exceeds $50,000,000, or that exceeds $5,000,000 and that is 5 percent or more of the funding target of the plan before such change.
(i) Special rules for at-risk plans
(1) Funding target for plans in at-risk status
(A) In general
In the case of a plan which is in at-risk status for a plan year, the funding target of the plan for the plan year shall be equal to the sum of—
(i) the present value of all benefits accrued or earned under the plan as of the beginning of the plan year, as determined by using the additional actuarial assumptions described in subparagraph (B), and
(ii) in the case of a plan which also has been in at-risk status for at least 2 of the 4 preceding plan years, a loading factor determined under subparagraph (C).
(B) Additional actuarial assumptions
The actuarial assumptions described in this subparagraph are as follows:
(i) All employees who are not otherwise assumed to retire as of the valuation date but who will be eligible to elect benefits during the plan year and the 10 succeeding plan years shall be assumed to retire at the earliest retirement date under the plan but not before the end of the plan year for which the at-risk funding target and at-risk target normal cost are being determined.
(ii) All employees shall be assumed to elect the retirement benefit available under the plan at the assumed retirement age (determined after application of clause (i)) which would result in the highest present value of benefits.
(C) Loading factor
The loading factor applied with respect to a plan under this paragraph for any plan year is the sum of—
(i) $700, times the number of participants in the plan, plus
(ii) 4 percent of the funding target (determined without regard to this paragraph) of the plan for the plan year.
(2) Target normal cost of at-risk plans
In the case of a plan which is in at-risk status for a plan year, the target normal cost of the plan for such plan year shall be equal to the sum of—
(A) the excess of—
(i) 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, determined using the additional actuarial assumptions described in paragraph (1)(B), plus
(II) the amount of plan-related expenses expected to be paid from plan assets during the plan year, over
(ii) the amount of mandatory employee contributions expected to be made during the plan year, plus
(B) in the case of a plan which also has been in at-risk status for at least 2 of the 4 preceding plan years, a loading factor equal to 4 percent of the amount determined under subsection (b)(1)(A)(i) with respect to the plan for the plan year.
(3) Minimum amount
In no event shall—
(A) the at-risk funding target be less than the funding target, as determined without regard to this subsection, or
(B) the at-risk target normal cost be less than the target normal cost, as determined without regard to this subsection.
(4) Determination of at-risk status
For purposes of this subsection—
(A) In general
A plan is in at-risk status for a plan year if—
(i) the funding target attainment percentage for the preceding plan year (determined under this section without regard to this subsection) is less than 80 percent, and
(ii) the funding target attainment percentage for the preceding plan year (determined under this section by using the additional actuarial assumptions described in paragraph (1)(B) in computing the funding target) is less than 70 percent.
(B) Transition rule
In the case of plan years beginning in 2008, 2009, and 2010, subparagraph (A)(i) shall be applied by substituting the following percentages for “80 percent”:
(i) 65 percent in the case of 2008.
(ii) 70 percent in the case of 2009.
(iii) 75 percent in the case of 2010.

(5) Transition between applicable funding targets and between applicable target normal costs
(A) In general
In any case in which a plan which is in at-risk status for a plan year has been in such status for a consecutive period of fewer than 5 plan years, the applicable amount of the funding target and of the target normal cost shall be, in lieu of the amount determined without regard to this paragraph, the sum of—
(i) the amount determined under this section without regard to this subsection, plus
(ii) the transition percentage for such plan year of the excess of the amount determined under this subsection (without regard to this paragraph) over the amount determined under this section without regard to this subsection.
(B) Transition percentage
For purposes of subparagraph (A), the transition percentage shall be determined in accordance with the following table:
  If the consecutive number of    The transi-    years (including the plan year) tion percent-    the plan is in at-risk status is— age is—  1 20    2 40    3 60    4 80.

For purposes of this paragraph, plan years beginning before 2008 shall not be taken into account.
(6) Small plan exception
If, on each day during the preceding plan year, a plan had 500 or fewer participants, the plan shall not be treated as in at-risk status for the plan year. For purposes of this paragraph, all defined benefit plans (other than multiemployer plans) maintained by the same employer (or any member of such employer’s controlled group) shall be treated as 1 plan, but only participants with respect to such employer or member shall be taken into account and the rules of subsection (g)(2)(C) shall apply.
(j) Payment of minimum required contributions
(1) In general
For purposes of this section, the due date for any payment of any minimum required contribution for any plan year shall be 81/2 months after the close of the plan year.
(2) Interest
Any payment required under paragraph (1) for a plan year that is made on a date other than the valuation date for such plan year shall be adjusted for interest accruing for the period between the valuation date and the payment date, at the effective rate of interest for the plan for such plan year.
(3) Accelerated quarterly contribution schedule for underfunded plans
(A) Failure to timely make required installment
In any case in which the plan has a funding shortfall for the preceding plan year, the employer maintaining the plan shall make the required installments under this paragraph and if the employer fails to pay the full amount of a required installment for the plan year, then the amount of interest charged under paragraph (2) on the underpayment for the period of underpayment shall be determined by using a rate of interest equal to the rate otherwise used under paragraph (2) plus 5 percentage points. In the case of plan years beginning in 2008, the funding shortfall for the preceding plan year may be determined using such methods of estimation as the Secretary may provide.
(B) Amount of underpayment, period of underpayment
For purposes of subparagraph (A)—
(i) Amount The amount of the underpayment shall be the excess of—
(I) the required installment, over
(II) the amount (if any) of the installment contributed to or under the plan on or before the due date for the installment.
