The total number of potential shares of common stock excluded from the diluted earnings per share computation because their inclusion would have been anti-dilutive was 18.7 million in 2014, 14.3 million in 2013 and 25.3 million in 2012.

During the period of April 2009 through December 2014, our Board of Directors has approved repurchases of up to an aggregate of $13.500 billion of our common stock, including the April 2014 authorization to repurchase an additional $4.000 billion of our common stock.

As part of the management of our share repurchase program, we may, from time to time, sell put options on our common stock with strike prices that we believe represent an attractive price to purchase our shares. If the trading price of our shares exceeds the strike price of the put option at the time the option expires, we will have economically reduced the cost of our share repurchase program by the amount of the premium we received from the sale of the put option. If the trading price of our stock is below the strike price of the put option at the time the option expires, we would purchase the shares covered by the option at the strike price of the put option. During 2014 and 2013, we recorded net gains of $11.6 million and $1.2 million, respectively, from selling put options on our common stock. At December 31, 2014, we had no outstanding put options.

We repurchased 22.0 million shares of common stock under the program from all sources during 2014 at a total cost of $2.928 billion, excluding transaction fees. As of December 31, 2014, we had a remaining open-ended repurchase authorization of $3.140 billion.
