Treasury Stock [Text Block] | 8. Share Repurchase Program In December 2007, our Board of Directors approved a share repurchase program to repurchase up to one million shares of our common stock either through purchases on the open market or through private transactions. The timing and extent to which we will repurchase shares depends on market conditions and other corporate considerations. In the first quarter of 2008 we repurchased and retired 67,500 shares of our common stock. We have made no purchases since the first quarter of 2008. The repurchase program does not have an expiration date.
