Repurchases Of Common Stock [Abstract] |
Repurchases Of Common Stock | NOTE 17. REPURCHASES OF COMMON STOCK Our board of directors has authorized the repurchase of up to 57,000,000 shares of our common stock in the open market or in negotiated transactions pursuant to the Company’s share repurchase program. We believe that the repurchase of our common stock is a favorable means of returning value to our shareholders, and we also repurchase to offset the dilutive effect of our share-based compensation programs. Repurchases of our common stock may vary d epending upon the level of other investing activities and the share price. As of December 31, 2014, there are 3,081,303 re maining shares available for repurchase under this authorization. The following is a summary of our open market common stock repurchases for the years ended December 31, 201 4, 201 3 and 201 2 (in thousands, except per share amounts):
|  | For the Years Ended December 31,

Total cost of shares repurchased |  | $ | 618,158 |  | $ | 367,761 |  | $ | 132,268
Average cost per share |  | $ | 126.66 |  | $ | 93.06 |  | $ | 89.72
We primarily acquire shares by means of repurchases in the open market. However, we also acquire shares that are sur rendered by employees in payment for the minimum required withholding taxes due on the vesting of restricted stock units and the settlement of deferred stock units, otherwise referred to herein as employee surrenders. We acquired 46,190 shares at a total cost of $5.8 million in connection with employee surrenders for the year ended December 31, 2014 compared to 49,475 shares at a total cost of $4.5 million for the year ended December 31, 2013 and 53,272 shares at a total cost of $4.7 million for the year ended December 31, 2012. W e issue shares of treasury stock upon the vesting of certain restricted stock units and upon the exercise of certain stock options. The number of shares of treasury stock issued during t he years ended December 31, 2014, 2013 and 2012 was not material.
