(5) No such grant, right, privilege or franchise shall be made to any person, firm, corporation or association unless it provides for adequate compensation or consideration therefor to be paid to such city, and regardless of whether or not other or additional compensation is provided for such grantee shall pay such fixed charge as may be prescribed in the franchise ordinance. Such fixed charge may consist of a percentage of the gross receipts derived from the service permitted by the grant, right, privilege or franchise from consumers or recipients of such service located within the corporate boundaries of such city, and, in case of public utilities or common carriers situated and operated wholly or principally within such city, or principally operated for the benefit of such city or its people, from consumers or recipients located in territory immediately adjoining such city and not within the boundaries of any other incorporated city; and in such case such city shall make and report to the governing body all such gross receipts once each month, or at such other intervals as stipulated in the franchise ordinance and pay into the treasury the amount due such city at the time the report is made. The governing body shall also have access to and the right to examine, at all reasonable times, all books, receipts, files, records and documents of any such grantee necessary to verify the correctness of such statement and to correct the same, if found to be erroneous. If such statement of gross receipts is incorrect, then such payment shall be made upon such corrected statement. On and after the effective date of the act, any provision for compensation or consideration, included in a franchise granted pursuant to this section which is established on the basis of compensation or consideration paid by the utility under another franchise, is hereby declared to be contrary to the public policy of this state and shall be void and unenforceable. Any such provision, included in a franchise granted pursuant to this section and in force on the effective date of this act which requires payments to the city by a utility to increase by virtue of the compensation or consideration required to be paid under a franchise granted by another city to the utility's predecessor in interest, is hereby declared to be contrary to the public policy of this state and shall be void and unenforceable.
