Shareholders' Equity and Share-based Payments [Text Block]	(8) SHAREHOLDERS' EQUITY: In February 2008, our Board of Directors approved a share repurchase plan under which up to $100.0 million of common shares can be purchased, and terminated the prior plan. During the three months ended March 31, 2012 and 2011, respectively, we purchased approximately 16,000 and 20,000 shares, with a value of approximately $0.8 million and $0.9 million, respectively. Those shares purchased were surrendered by our employees in connection with the vesting of restricted share units and used by us to satisfy payment of our minimum federal income tax withholding obligations in connection with these vestings. These share purchases were outside of our repurchase plan.
