INS §10089.53: (a) Any insurer that withdraws from the authority under Section 10089.

(a) Any insurer that withdraws from the authority under Section 10089.19 while bonds or other debt is outstanding shall impose annually a premium surcharge on each policy of residential earthquake insurance written by it equal in percentage amount, calculated as a percentage of the basic residential earthquake insurance premium, to the percentage amount of the surcharge being imposed in that year by the authority pursuant to subdivision (b) of Section 10089.29. That insurer shall remit promptly all those surcharges collected by it to the trustee appointed pursuant to Section 10089.22. The surcharges shall be used solely to repay the bonded indebtedness or other debt issued pursuant to subdivision (a) of Section 10089.29. If the sum of the surcharges remitted to the trustee pursuant to this section plus the amount of the surcharges imposed by the authority pursuant to subdivision (b) of Section 10089.29 would exceed the amount authorized by that provision, then surcharges of the authority shall be reduced by an amount equal to that excess. (b) Should the Legislature and Governor approve legislation that causes the authority to cease operation while bonds or other debt are outstanding, participating insurers shall impose annually a premium surcharge on each policy of residential earthquake insurance written by them equal in percentage amount, calculated as a percentage of the basic residential earthquake insurance premium, to the percentage amount of the surcharge being imposed in that year by the authority pursuant to subdivision (b) of Section 10089.29. Those insurers shall remit promptly all these surcharges collected by them to the trustee appointed pursuant to Section 10089.22. The surcharges shall be used solely to repay the bonded indebtedness or other debt issued pursuant to subdivision (a) of Section 10089.29. If the sum of the surcharges remitted to the trustee pursuant to this section plus the amount of the surcharges imposed by the authority pursuant to subdivision (b) of Section 10089.29 would exceed the amount authorized by that provision, then surcharges of the authority shall be reduced by an amount equal to that excess.
