13. Treasury Stock

On September 17, 2001, the Company announced an open market stock repurchase program to purchase up to one million shares of outstanding Company common stock, subject to market conditions and other factors. Any purchases under the Company's stock repurchase program may be made from time to time without prior notice. On July 26, 2006, the Company announced that it had expanded the existing open market stock repurchase program to enable the Company to purchase up to an additional three million shares of the Company's outstanding common stock, bringing the total number of shares authorized for repurchase to four million shares. Through September 30, 2011, the Company had repurchased a total of 1,756,794 shares of common stock through the open market stock repurchase program. The Company repurchased 1,270,000 shares for $16.2 million under the program during the six months ended September 30, 2011.

In connection with the vesting and release of the restriction on previously vested shares of restricted stock, the Company repurchased 79,321 shares for $1.6 million related to minimum statutory tax withholding requirements on these restricted stock units during the six months ended September 30, 2011. These repurchase transactions do not fall under the repurchase program described above, and therefore do not reduce the amount that is available for repurchase under that program.
