(a) General rule.--No contract or arrangement providing for the furnishing of management, supervisory, construction, engineering, accounting, legal, financial, or similar services, and no contract or arrangement for the purchase, sale, lease, or exchange of any property, right, or thing or for the furnishing of any service, property, right or thing other than those above enumerated, made or entered into after the effective date of this section between a public utility and any affiliated interest shall be valid or effective unless and until such contract or arrangement has received the written approval of the commission. If such contract is oral, a complete statement of the terms and conditions thereof shall be filed with the commission and subject to its approval.

(b) Filing and action on contract.--It shall be the duty of every public utility to file with the commission a verified copy of any such contract or arrangement, or a verified summary as described in subsection (a) of any such unwritten contract or arrangement. All such contracts and arrangements, whether written or unwritten, entered into prior to the effective date of this section and required to be on file with the commission by prior act and in full force and effect at the effective date of this section shall be subject to the provisions of the sections regarding affiliated interests. The commission shall approve such contract or arrangement made or entered into after the effective date of this section only if it shall clearly appear and be established upon investigation that it is reasonable and consistent with the public interest. If at the end of 30 days after the filing of a contract or arrangement, no order of rejection has been entered, such contract or arrangement, whether written or unwritten, shall be deemed, in fact and law, to have been approved. The commission may, by written order, giving reasons therefor, extend the 30-day consideration period. No such contract or arrangement shall receive the commission's approval unless satisfactory proof is submitted to the commission of the cost to the affiliated interest of rendering the services or of furnishing the property or service described herein to the public utility. No proof shall be satisfactory within the meaning of the foregoing sentence unless it includes the original (or verified copies) of the relevant cost records and other relevant accounts of the affiliated interest, or such abstract thereof or summary taken therefrom as the commission may deem adequate, properly identified and duly authenticated. The commission may, where reasonable, approve or disapprove such contracts or arrangements without the submission of such cost records or accounts.

(c) Disallowance of excessive amounts.--If the commission shall determine that the amounts paid or payable under a contract or arrangement filed in accordance with this section are in excess of the reasonable price for furnishing the services provided for in the contract, or that such services are not reasonably necessary and proper, it shall disallow such amounts, insofar as found excessive, in any proceeding involving the rates or practices of the public utility. In any proceeding involving such amounts, the burden of proof to show that such amounts are not in excess of the reasonable price for furnishing such services, and that such services are reasonable and proper, shall be on the public utility.

(d) Exceptions.--The provisions requiring the written approval of the commission shall not apply to transactions with affiliated interests of any common carrier by railroad or motor vehicle that is subject to the Interstate Commerce Act unless required by order of the commission, nor where the amount of consideration involved is not in excess of $10,000 or 5% of the par value of outstanding common stock, whichever is smaller. Regularly recurring payments under a general or continuing arrangement which aggregate a greater annual amount shall not be broken down into a series of transactions to come within this exemption. Where the commission has given its approval generally as to a class or category of transactions, the commission may apply such approval to all subsidiary or related transactions. Such transactions shall be valid or effective without commission approval under this section. However, in any proceeding involving the rates or practices of the public utility, the commission may disallow any payment or compensation made pursuant to such transaction unless the public utility shall establish the reasonableness of such payment or compensation.
