In general
Treatment of certain income items
Any item of income which is properly taken into account for any recognition period taxable year but which is attributable to periods before the acquisition date shall be treated as a recognized built-in gain for the taxable year in which it is properly taken into account and shall be taken into account in determining the amount of the net unrealized built-in gain.

The term “gain corporation” means any corporation with a net unrealized built-in gain.
Control
The term “control” means ownership of stock in a corporation which meets the requirements of section 1504(a)(2).
Treatment of members of same group
Except as provided in regulations and except for purposes of subsection (b), all corporations which are members of the same affiliated group immediately before the acquisition date shall be treated as 1 corporation.
