16 C.F.R. § 802.6
(b)
(2) The portion of a mixed transaction that does not require advance competitive review and approval by a regulatory agency is subject to the act and these rules as if it were being acquired in a separate acquisition.
Example:Bank “A” acquires Bank “B”, which owns a financial subsidiary engaged in securities underwriting. “A”'s acquisition of “B” requires agency approval by the Office of the Comptroller of the Currency, the Board of Governors of the Federal Reserve System or Federal Deposit Insurance Corporation (depending on whether “A” is a national bank, state member bank, or state non-member bank under section 18(c) of the FDI Act), and therefore is exempt from filing under Section 7A (c)(7). However, the acquisition of the financial subsidiary is subject to HSR reporting requirements, and “A” and “B” each must make a filing for that portion of the transaction and observe the waiting period if the act's thresholds are met.
