A combination shall include any acquisition required to be accounted for by the surviving financial institution in accordance with generally accepted accounting principles or a statutory merger or consolidation.
(c) If a United States person included in a unitary business group of financial institutions or a financial institution combined return is subject to tax under chapter 11 or 12, any business income or equity capital attributable to that person shall be eliminated from the total equity capital of the unitary business group and any sales or gross business attributable to that person shall be eliminated from the apportionment formula under this chapter.
