NEW YORK (Standard&Poor's) June 12, 2003--Standard&Poor's Ratings Services said today that AutoZone Inc.'s (BBB+/Stable/A-2) announcement that it has increased its share repurchase authorization by $500 million has no immediate impact on the ratings and outlook. Standard&Poor's had previously factored additional share repurchase activity into the ratings and outlook on the company. Because AutoZone continues to achieve positive same-store sales and to improve operating efficiencies, share repurchase activity is expected to be managed so as to not have a significant impact on credit protection measures.
