Stockholders’ Equity

Share repurchase plan – In the third quarter of 2013, we acquired 14 million common shares at a cost of $500 million under our share repurchase program, initially authorized in 2006, bringing our total repurchases to 92 million common shares at a cost of $3,722 million. In December 2013, our Board of Directors increased the authorization by an additional $1.2 billion, bringing the total remaining share repurchase authorization to $2.5 billion. Purchases under the program may be in either open market transactions, including block purchases, or in privately negotiated transactions using cash on hand, cash generated from operations, proceeds from potential asset sales or cash from available borrowings to acquire shares. This program may be changed based upon our financial condition or changes in market conditions and is subject to termination prior to completion. The repurchase program does not include specific price targets or timetables.
