Item 9A. Controls and Procedures

As of August 26, 2017, an evaluation was performed under the supervision and with the participation of AutoZone’s management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as amended. Based on that evaluation, our management, including the Chief Executive Officer and the Chief Financial Officer, concluded that our disclosure controls and procedures were effective. During or subsequent to the quarter ended August 26, 2017, there were no changes in our internal controls that have materially affected or are reasonably likely to materially affect, internal controls over financial reporting.
