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. During 2015, we repurchased 91.9 million shares of Common Stock at an average cost of $39.43 per share, or an aggregate cost of $3.6 billion, all of which was paid during 2015. All share repurchases were funded through available cash and commercial paper issuances. During 2014, we repurchased 51.9 million shares of Common Stock at an average cost of $36.43 per share, or an aggregate cost of $1.9 billion. As of December 31, 2015, we have $5.4 billion in remaining share repurchase capacity.

In December 2013, we initiated an accelerated share repurchase (“ASR”) program. On December 3, 2013, we paid $1.7 billion and received an initial delivery of 44.8 million shares of Common Stock valued at $1.5 billion. We increased treasury stock by $1.5 billion, and the remaining $0.2 billion was recorded against additional paid in capital. In May 2014, the ASR program concluded and we received an additional 5.1 million shares, valued at $0.2 billion, for a total of 49.9 million shares with an average repurchase price of $34.10 per share over the life of the ASR program. The final settlement was based on the volume-weighted average price of our Common Stock during the purchase period less a fixed per share discount. Upon conclusion of the ASR program and receipt of the remaining repurchased shares, the $0.2 billion recorded in additional paid in capital was reclassified to treasury stock.
