Stock Repurchase Program

Stock Repurchase Program

On February 27, 2013, our board of directors modified our stock buyback program originally adopted in February 2009 to increase repurchases to an aggregate of $7.0 million, and subsequently, on March 13, 2013, increased the stock buyback program again for repurchases of up to an aggregate of $12.0 million. During the years ended December 31, 2013 and 2012, we repurchased 1,514,843 and 490,816 shares of our common stock, respectively, under the stock buyback program. During the year ended December 31, 2014, we did not repurchase any of our common stock. As of December 31, 2014, an aggregate of $6.3 million remains authorized for stock buyback under the program.
