Subject to the approval of the State Bank Commissioner, a nonstock savings bank may reorganize so as to become a mutual holding company and, in connection with such reorganization, form a stock savings bank subsidiary of the holding company in accordance with such regulations, orders or procedures as may be established or issued by the Commissioner. Any regulations, orders and procedures established or issued by the Commissioner pursuant to this section shall be similar in scope and content to, and comply in all material respects with, the mutual holding company regulations for savings associations of the Office of Thrift Supervision (or any successor federal banking agency) as currently in effect at the time the nonstock savings bank applies to the Commissioner for approval of the proposed holding company reorganization; provided, that the Commissioner may exempt the savings bank from any regulatory requirement imposed by such Office of Thrift Supervision regulations, including, but not limited to, any requirement that the mutual holding company formation be approved by the nonstock savings bank's depositors; and provided further, that conformity with the regulatory requirements imposed by the Office of Thrift Supervision will not be sufficient for state regulatory purposes if the Commissioner determines that the proposed formation of the mutual holding company would pose a risk to the savings bank's safety and soundness, violate any law or regulation or present a breach of fiduciary duty. Any issuance of stock in the newly-formed savings bank subsidiary of said mutual holding company to any person or entity other than the mutual holding company shall be conducted in accordance with the requirements and procedures for a mutual-to-stock conversion of a savings bank as prescribed by § 1664 of this title.
