Common Stock Repurchase Program

In December 2010, the Board of Directors authorized the repurchase of up to $20.0 million of the Company's common stock through open-market transactions and privately negotiated transactions from time to time at the discretion of management. Under the program, the purchases will be funded from available working capital, and any repurchased shares will be returned to authorized but unissued status. The duration of the repurchase program was two years and ended in December 2012. Under the program, the Company repurchased common stock with a value of $3.9 million. The Company did not repurchase any shares of common stock during 2012.
