§ 1.381(c)(11)-1. Contributions to pension plan, employees' annuity plans, and stock bonus and profit-sharing plans.

In 1955, X Corporation, which makes its return on the basis of the calendar year, paid $400,000 to completely fund past service credits under a qualified pension plan and deducted 10 percent ($40,000) of that cost in each of the taxable years 1955, 1956, and 1957. The pension plan established by X Corporation had an anniversary date of January 1. On December 31, 1957, on which date the undeducted part of the cost amounted to $280,000, X Corporation transferred all its assets to Y Corporation in a statutory merger to which section 361 applies. Y Corporation, which also makes its return on the basis of the calendar year, had a qualified pension plan and trust which also had an anniversary date of January 1. Since Y Corporation had many more employees than X Corporation on the date of transfer, it covered the former employees of X Corporation under its own plan. Y Corporation is entitled to deductions under section 404(a)(1)(D) and this section in 1958 and succeeding taxable years, in order of time, with respect to the undeducted balance of $280,000, to the extent of the difference between the amount paid and deductible by that corporation in each such taxable year and the maximum amount deductible by that corporation for such taxable year in accordance with the applicable limitations of section 404(a)(1). In computing the maximum amount deductible by Y Corporation for 1958 and 1959 under section 404(a)(1)(C), that corporation may include $40,000 for each year, the amount that X Corporation could have included for each of those years in computing the maximum amount that would have been deductible by X Corporation under section 404(a)(1)(C) if the merger had not occurred. Thus, assuming that Y Corporation's appropriate limitation so computed under section 404(a)(1)(C) is $1,000,000 (including the $40,000 carried over from X Corporation under this section) for each of those taxable years, and that Y Corporation contributed $925,000 to its trust in 1958 and $975,000 in 1959, then Y Corporation is entitled under section 404(a)(1)(D) and this section to deduct in 1958 $75,000, and in 1959 $25,000, of the amount ($280,000) carried over from X Corporation. The undeducted balance of such amount ($180,000) available to Y Corporation on December 31, 1959, would be deductible by that corporation in succeeding taxable years in accordance with section 404(a)(1)(D) and this section.
