installment acceleration amount
(i)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)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).

(II)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)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)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.
