Stock Repurchase Plan [Abstract] |
Stock Repurchase Plan | 10. Stock Repurchase Plan In November 2003, the Company’s Board of Directors authorized the Company to repurchase up to an aggregate of $15 million in value of common stock in open market purchases from time to time at the discretion of the Company’s management depending on market conditions and other corporate considerations. The Company’s Board of Directors amended the program on various dates, increasing the repurchase amount authorized and extending the expiration date. At December 31, 2015, approximately $70 million of the Company’s share repurchase authorization was remaining for repurchases through December 31, 2016. All of the Company’s share repurchases were effected in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended. This stock repurchase plan may be modified, suspended or terminated at any time by the Company without notice. A summary of the Company’s stock repurchase activity for the years ended December 31, 2013, 2014, and 2015, all of which was part of a publicly announced plan, is set forth in the table below:
|  | Number of shares repurchased |  | Average price paid per share |  | Amount available for future repurchases (in millions)
2013 |  | 495,085 |  | $ | 50.49 |  | $ | 70.0
2014 |  | — |  | $ | — |  | $ | 70.0
2015 |  | — |  | $ | — |  | $ | 70.0
Repurchases of common stock are recorded as a reduction to additional paid-in capital. To the extent additional paid-in capital had been reduced to zero through stock repurchases, retained earnings was then reduced.
