For purposes of this subparagraph, the term “stock bonus or profit-sharing trust” shall not include any trust designed to provide benefits upon retirement and covering a period of years, if under the plan the amounts to be contributed by the employer can be determined actuarially as provided in paragraph (1).
If the contributions are made to 2 or more stock bonus or profit-sharing trusts, such trusts shall be considered a single trust for purposes of applying the limitations in this subparagraph.
Except as provided by the Secretary, a defined contribution plan which is subject to the funding standards of section 412 shall be treated in the same manner as a stock bonus or profit-sharing plan for purposes of this subparagraph.

A defined contribution plan which is a pension plan shall not be treated as failing to provide definitely determinable benefits merely by limiting employer contributions to amounts deductible under this section.

If, in connection with 1 or more defined contribution plans and 1 or more defined benefit plans, no amounts (other than elective deferrals (as defined in section 402(g)(3))) are contributed to any of the defined contribution plans for the taxable year, then subparagraph (A) shall not apply with respect to any of such defined contribution plans and defined benefit plans.
if such contributions exceed 6 percent of such compensation, this paragraph shall be applied by only taking into account such contributions to the extent of such excess.
For purposes of this clause, amounts carried over from preceding taxable years under subparagraph (B) shall be treated as employer contributions to 1 or more defined contributions plans to the extent attributable to employer contributions to such plans in such preceding taxable years.

The amount deductible under this paragraph shall not, however, exceed 25 percent of the compensation otherwise paid or accrued during the taxable year to the employees under such employee stock ownership plan. Any amount paid into such trust in any taxable year in excess of the amount deductible under this paragraph shall be deductible in the succeeding taxable years in order of time to the extent of the difference between the amount paid and deductible in each such succeeding year and the maximum amount deductible for such year under the preceding sentence.
Notwithstanding the provisions of paragraphs (3) and (7), if contributions are made to an employee stock ownership plan (described in subparagraph (A)) and such contributions are applied by the plan to the repayment of interest on a loan incurred for the purpose of acquiring qualifying employer securities (as described in subparagraph (A)), such contributions shall be deductible for the taxable year with respect to which such contributions are made as determined under paragraph (6).
