Share Repurchase Program:

During 2013, our Board of Directors authorized the repurchase of $7.7 billion of our Common Stock through December 31, 2016. On July 29, 2015, our Finance Committee, with authorization delegated from our Board of Directors, approved an increase of $6.0 billion in the share repurchase program, raising the authorization to $13.7 billion of Common Stock repurchases, and extended the program through December 31, 2018. Repurchases under the program are determined by management and are wholly discretionary. Prior to January 1, 2017, we had repurchased $10.8 billion of Common Stock pursuant to this authorization. During the six months ended June 30, 2017, we repurchased approximately 25 million shares of Common Stock at an average cost of $44.61 per share, or an aggregate cost of approximately $1,109 million, all of which was paid during the period except for approximately $40 million settled in July 2017. All share repurchases were funded through available cash and commercial paper issuances. As of June 30, 2017, we have $1.7 billion in remaining share repurchase capacity.
