Cal. INS § 937.4

(a) Failure to submit a report under Section 937.1 shall subject an admitted insurer to a civil penalty to be fixed by the commissioner, not to exceed five thousand dollars ($5,000) for each 30-day period that the insurer is not in compliance, unless the failure to comply is willful, in which case the civil penalty shall be in an amount not to exceed ten thousand dollars ($10,000) for each 30-day period that the insurer is not in compliance, but not to exceed an aggregate amount of one hundred thousand dollars ($100,000). The commissioner shall collect the amount payable and may bring an action in the name of the people of the State of California to enforce collection. These penalties shall be in addition to other penalties provided by law.

(b) An insurer may request, and the commissioner may grant, a 30-day extension to submit a report pursuant to Section 937.1 if needed due to unintended or unforeseen delays. If the insurer fails to submit a report pursuant to Section 937.1 after the granted 30-day extension has passed, the commissioner may find that the failure to submit the report was willful and increase the civil penalty to an amount not to exceed ten thousand dollars ($10,000) for each 30-day period that the insurer is not in compliance, but not to exceed an aggregate amount of one hundred thousand dollars ($100,000).

(c) The penalty imposed by this section may be appealed by means of a remedy provided by Section 12940, or by Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code.

(d) The commissioner may consider an insurer’s violation of this section or article as the basis for other enforcement action against an insurer, as authorized by law.
