Whenever such an insurer fails to maintain the financial condition required by section 12091, the commissioner shall require the deficiency to be made up in sixty days. If it is not made up as required, he shall issue a certificate showing the extent of such deficiency. He shall publish the certificate once a week for three weeks, in a daily San Francisco paper. From the time of first publication until such deficiency is made up, the insurer shall not do business in this State.
