Common Stock Repurchase Program
Our Board of Directors adopted a program that authorizes repurchases of our common stock up to $2 billion. In October 2015, our Board of Directors extended its authorization through December 31, 2016. Shares of our common stock may be purchased in the open market, including through block purchases, or through privately negotiated transactions, or pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended. The timing, manner, price and amount of any repurchases will be determined at our discretion and the program may be suspended, terminated or modified at any time for any reason. Among other factors, we intend to only consider repurchasing shares of our common stock when the purchase price is less than our estimate of our current net asset value per common share. Generally, when we repurchase our common stock at a discount to our net asset value, the net asset value of our remaining shares of common stock outstanding increases. In addition, we do not intend to repurchase any shares from directors, officers or other affiliates. The program does not obligate us to acquire any specific number of shares, and all repurchases will be made in accordance with Rule 10b-18, which sets certain restrictions on the method, timing, price and volume of stock repurchases.
We did not repurchase any shares of our common stock during the three months ended June 30, 2016. During the six months ended June 30, 2016, we repurchased 6.5 million shares of our common stock at an average repurchase price of $17.89 per share, including expenses, totaling $116 million. During the three and six months ended June 30, 2015 we repurchased 4.0 million shares of our common stock at an average repurchase price of $19.86 per share, including expenses, totaling $79 million. As of June 30, 2016, the total remaining amount authorized for repurchases of our common stock was $0.6 billion.
