A bank that is a trust institution may maintain separate departments and deposit in its commercial department to the credit of its trust department all uninvested fiduciary funds of cash and secure all such deposits in the name of the trust department, whether in consolidated deposits or for separate fiduciary accounts, by segregating and delivering to the trust department such securities as are required by N.C. Gen. Stat. § 53-163.1 for such deposits. Such securities shall be held by the trust department as security for the full payment or repayment of all such deposits and shall be kept separate and apart from other assets of the trust department. Until all of the deposits shall have been accounted for to the trust department or to the individual fiduciary accounts, no creditor of the bank shall have any claim or right to such security. When fiduciary funds are deposited by the trust department in the commercial department of the bank, the deposit thereof shall not be deemed to constitute a use of such funds in the general business of the bank. To the extent and in the amount such deposits may be insured by the FDIC, the amount of security required for such deposits by this section may be reduced. The Banking Commission shall have power to make such rules as it may deem necessary for the enforcement of the provisions of this section. (2012-56, s. 10.)
