(b) An insurer holding a valid certificate of authority to transact insurance in this state immediately prior to the effective date of this title may continue to be authorized to transact the same kinds of insurance as permitted by such certificate of authority by maintaining thereafter not less than the same amount of paid-in capital stock, if a stock insurer, or not less than the same amount of surplus, if a mutual or reciprocal insurer, as required by the laws of this state for such authority immediately prior to such effective date; but such insurer shall not thereafter be granted authority to transact any other or additional kind of insurance unless it then fully complies with the requirements as to capital and surplus, as applied to all kinds of insurance it then proposes to transact, as provided by this title with respect to insurers applying for original certificates of authority under this title.
