Effect on earnings and profits.
(4) Effect on earnings and profits. The disallowance of a deduction under section 267A does not affect whether the amount paid or accrued that gave rise to the deduction reduces earnings and profits of a corporation. However, for purposes of section 952(c)(1) and 1.952-1(c), a CFC's earnings and profits are not reduced by a specified payment a deduction for which is disallowed under section 267A, if a principal purpose of the transaction pursuant to which the payment is made is to reduce or limit the CFC's subpart F income.
