Share Repurchase Program: During the period of April 2009 through March 31, 2016, our Board of Directors approved repurchases of up to an aggregate of $17.500 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 the three-month periods ended March 31, 2016 and 2015, we recorded gains from put option activity on our Consolidated Statements of Income in Other income (expense), net as follows:



	Three-Month Periods Ended March 31,
	2016		2015

At March 31, 2016, we had no outstanding put options.

We have purchased 14.1 million shares of common stock under the share repurchase program from all sources at a total cost of $1.410 billion during the three-month period ended March 31, 2016. As of March 31, 2016, we had a remaining share repurchase authorization of $2.481 billion.
