On January 12, 2016, our board of directors authorized us to repurchase a total of up to 10,000,000 shares of our outstanding common stock.  This authorization reaffirmed and incorporated the then-current balance of 4,000,000 shares that remained under the prior board-approved share repurchase program. The amount and timing of shares purchased under this 10,000,000 share repurchase program will be subject to market and business conditions and other factors, and purchases may be made from time to time and at any time through open market or privately negotiated transactions.  This share repurchase authorization will continue in effect until fully used or earlier terminated or suspended by the board of directors. As of January 22, 2016, we had repurchased 3,025,000 shares of our common stock pursuant to this authorization, at a total cost of $30.5 million.
