Stock Repurchase Program
8.           Stock Repurchase Program

In November 2009, the Board of Directors (Board) authorized a new Stock Repurchase Program (Program) of $250.0 million to repurchase our common stock through February 2, 2013.  The Program replaced our existing plan that was adopted in August 2004.  Stock repurchases may be made in the open market or in negotiated transactions, with the amount and timing of repurchases dependent on market conditions, vesting schedules of equity awards and at the discretion of our management.

We repurchased 732,547 shares of our common stock during the thirteen weeks ended April 30, 2011 at a cost of $23.7 million, including 35,547 shares acquired from holders of restricted stock unit awards to satisfy tax withholding requirements of $1.1 million.  As of April 30, 2011, we have approximately $189.6 million remaining available under the Program for stock repurchase.

Under the old authorization approved by the Board in August 2004, we repurchased 7,761,813 shares of our common stock at an approximate cost of $166.9 million.  Under both authorizations, we have acquired a total of 9,955,585 shares of our common stock at an approximate cost of $228.5 million.
