If an industrial loan company fails to pay the assessment provided in Section 18350 on or before the 30th day of December following the day upon which payment is due, the commissioner may by order summarily suspend or revoke the certificate issued to that company. If, after such an order is made, a request for hearing is filed in writing within 15 days from the date of service of the order and a hearing is not held within 60 days thereafter, the order is deemed rescinded as of its effective date. During any period when its certificate is revoked or suspended, a company shall not issue thrift certificates or make loans or otherwise conduct business
pursuant to this division except as may be permitted by order of the commissioner; provided, however, that neither the revocation, suspension or surrender of a certificate shall affect the powers of the commissioner as provided in this division.
This section shall become operative January 1, 1969. For the purpose of making its provisions operative, the commissioner shall issue to all industrial loan companies authorized to conduct business under this division on said date a certificate of authorization to conduct business pursuant to this division in such form as the commissioner may prescribe and as provided in Section 18101 and thereafter all such companies shall be conclusively presumed to be conducting business under this division pursuant to such certificate of authorization.
