Accordingly, the agency is amending the regulations in 21 CFR 520.48, 520.905a, 520.905b, 520.905c, 520.905d, 520.905e, 520.1010a, 520.1010b, 520.1010c, 522.1010, 522.2476, 522.2477, 558.55, 558.58, 558.95, 558.198, 558.258, 558.265, 558.355, 558.363, 558.366, and 558.550 to reflect the transfers of ownership.
