The commissioner may require an insurer to file an audited financial report earlier than June 1 with ninety days advance notice to the insurer.

(2) Extensions of the June 1 filing date may be granted by the commissioner for thirty-day periods upon a showing by the insurer and its independent certified public accountant of the reasons for requesting an extension and determination by the commissioner of good cause for an extension. The request for extension must be submitted in writing not less than ten days prior to the due date in sufficient detail to permit the commissioner to make an informed decision with respect to the requested extension.

(3) If an extension is granted in accordance with the provisions in subsection (2) of this section, a similar extension of thirty days is granted to the filing of management's report of internal control over financial reporting.
