In any proceeding where the issue is properly before it, the Oklahoma Corporation Commission may require an audit of all amounts received from customers under an irrevocable and nonbypassable mechanism and paid to a utility, the amounts paid by the utility to the Oklahoma Development Finance Authority or other holder of securitization property. An audit, as provided in this section, shall be part of any general rate case filed by a regulated utility currently affected by a financing order with outstanding ratepayer-backed bonds. Any audit conducted pursuant to this section shall be provided to the Governor, the Pro Tempore of the Senate, the Speaker of the House of Representatives and the Authority; provided, however, any part or parts of the audit deemed confidential pursuant to federal or state law or as determined by the Commission, shall be redacted.
