On June 16, 2010, the company’s board of directors authorized a share repurchase program of up to $2.0 billion of the company’s common stock. Following this initial authorization, the board of directors increased the remaining repurchase authorization to $4.0 billion in April 2011. After further repurchases reduced the remaining authorization to less than $1 billion, the board of directors again increased the remaining authorization to $2.0 billion in September 2012. As of December 31, 2012, repurchases under the program totaled $3.9 billion, and $1.5 billion remained under this share repurchase authorization.
