A “stock insurer” is an incorporated insurer with its capital divided into shares and owned by its stockholders. Unless otherwise provided, the insurance department or division of a corporation established under Chapter 7 of Title 5 (but not the corporation itself) shall be deemed to be a stock insurer for purposes of this title, even though it has no capital divided into shares and owned by stockholders.
