A holding company must apply and register with the Commissioner on or before 90 days after the date the company becomes a holding company. The application must include information on the financial condition, ownership, operations, management, and intercompany relations of the holding company and its subsidiaries, and on related matters the Commissioner finds necessary and appropriate. On written request, the Commissioner may, in his or her sole discretion, extend the time within which a holding company is required to register and file the required information.
