Combinations.
(1) Combinations. The net unrecognized section 987 gain or loss of a combined QBU (as defined in 1.987-2(c)(9)(i)) for a taxable year is determined under paragraph (b) of this section by taking into account the net accumulated unrecognized section 987 gain or loss of each combining QBU (as defined in 1.987-2(c)(9)(i)) for all prior taxable years to which the regulations under section 987 apply, as determined under paragraph (c) of this section, and by treating the combining QBUs as having combined immediately prior to the beginning of the taxable year of combination. See paragraph (f)(3) of this section, Example 1, for an illustration of this rule.
