Upon written request during normal business hours, any duly authorized representative of the city shall have the right to inspect and audit the grantee's records showing the gross receipts from which its franchise fee payments are computed. Any such inspection or audit shall take place within twenty-four months following the respective calendar year and records thereof in question. If an underpayment of the franchise fee in an amount exceeding five percent of the amount actually due to the city is determined in such inspection or audit conducted by or at the direction of the city, then the reasonable cost of such inspection or audit shall be at the expense of the grantee. (Ord. 93-03 §5 (part), 1993)
