12 CFR 559.10 - How must separate corporate identities be maintained?
(a) Each savings association and subordinate organization thereof must be operated in a manner that demonstrates to the public that each maintains a separate corporate existence. Each must operate so that:
(1) Their respective business transactions, accounts, and records are not intermingled;
(2) Each observes the formalities of their separate corporate procedures;
(3) Each is adequately financed as a separate unit in light of normal obligations reasonably foreseeable in a business of its size and character;
(4) Each is held out to the public as a separate enterprise; and
(b) OTS regulations that apply both to savings associations and subordinate organizations shall not be construed as requiring a savings association and its subordinate organizations to operate as a single entity.
