(e) Any insurance company, with respect to its general account or separate accounts, is authorized to deposit or arrange for the deposit of securities which it may own in a clearing corporation, as defined in Section 7-8-102(3), or in a federal reserve bank under book-entry system. When such securities are so deposited, certificates representing securities of the same class of the same issuer may be merged and held in bulk in the name of the nominee of such clearing corporation with any other securities deposited in such clearing corporation by any person, regardless of the ownership of such securities, and securities of small denominations may be merged into one or more certificates of larger denominations. Title to such securities may be transferred by bookkeeping entry on the books of such clearing corporation or federal reserve bank without physical delivery of certificates representing such securities. Any company making deposits by means of such securities shall provide to the commissioner evidence customarily issued by federal reserve banks and clearing corporations establishing that the securities are actually recorded in a book-entry account or actually held in safekeeping by a clearing corporation. Securities deposited in a clearing corporation or in a book-entry account and used to meet the deposit requirements under the insurance laws of this state shall be under the control of the commissioner and shall not be withdrawn by the insurance company without the approval of the commissioner.
