We have a share repurchase program for our common stock under which we may purchase shares on the open market or through privately negotiated transactions.  We currently have Board authorization through May 2013 to repurchase up to an aggregate of 2.8 million shares, but not to exceed $100 million. No shares of common stock were repurchased pursuant to this program during the six months ended June 30, 2012. Since the plan's inception in 2000 a total of 2.1 million shares have been repurchased at a total cost of $83.3 million.
