Stock Repurchase Programs

During the three and nine months ended September 30, 2011, we retired a total of $883.6 million or 22.4 million shares of common stock and $2.16 billion or 54.2 million shares of common stock, respectively. We completed our May 2010, three-year, $5.00 billion stock repurchase program, which retired 135.5 million shares at an average purchase price of $36.89 per share. Upon completion of this repurchase program, we initiated purchases under our January 2011, three-year, $5.00 billion stock repurchase program. As of September 30, 2011, the remaining authorized amount of stock repurchases that may be made under our repurchase program was $4.82 billion.

We use the par value method of accounting for our stock repurchases. Under the par value method, common stock is first charged with the par value of the shares involved. The excess of the cost of shares acquired over the par value is allocated to additional paid-in capital (APIC) based on an estimated average sales price per issued share with the excess amounts charged to retained earnings. As a result of our stock repurchases during the nine months ended September 30, 2011, we reduced common stock and APIC by an aggregate of $168.2 million and charged $2.00 billion to retained earnings.
