In September, 2001, the Board of Directors of the Company authorized a program to repurchase the Company’s common stock in open market or negotiated transactions using available cash, cash equivalents and investments.   As of December 31, 2011 there were approximately 2.2 million shares remaining authorized for repurchase under a repurchase program. During February 2012, the Board of Directors increased the shares authorized for repurchase from the amount available to repurchase by approximately 2.8 million shares to a total of 5.0 million shares. There were 0.4 million shares repurchased during the three and six months ended June 30, 2012. As of June 30, 2012 the total shares authorized for repurchase is 4.6 million shares and does not have an expiration date.

Subsequent to June 30, 2012 the Company repurchased 0.7 million shares further reducing the authorized shares for repurchase to 3.96 million. The specific timing and amount of repurchases will be determined by market conditions, cash flow requirements, securities law limitations, and other factors. Repurchases will continue from time to time, as conditions permit, until the number of shares authorized to be repurchased have been bought, or until the authorization to repurchase is terminated, whichever occurs first. The share repurchase authorization is discretionary and has no expiration date. The repurchase program may be suspended, modified, or discontinued at any time.
