The Grantee agrees that the City, upon 30 days’ written notice to the Grantee and no more than once annually, may review such of its books and records at the Grantee’s business office, during normal business hours and on a non-disruptive basis, as is reasonably necessary to ensure compliance with the terms of this franchise. Such notice shall specifically reference the subsection of the franchise which is under review, so that the Grantee may organize the necessary books and records for easy access by the City. Alternatively, if the books and records are not easily accessible at the local office of the Grantee, the Grantee may, at its sole option, choose to pay the reasonable travel costs of the City’s representative to view the books and records at the appropriate location. The Grantee shall not be required to maintain any books and records for franchise compliance purposes longer than three years. Notwithstanding anything to the contrary set forth herein, the Grantee shall not be required to disclose information that it reasonably deems to be proprietary or confidential in nature, or to disclose books and records of any affiliate that is not providing cable service in the service area. The City agrees to treat any information disclosed by the Grantee as confidential and only to disclose it to employees, representatives, and agents thereof that have a need to know, or in order to enforce the provisions hereof. The Grantee shall not be required to provide subscriber information in violation of Section 631 of the Cable Act.
