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 nine months ended September 30, 2011 and 2010, respectively, we purchased approximately 137,000 and 102,000 shares, with a value of approximately $6.6 million and $3.9 million, respectively. Of those shares purchased, 22,000 and 31,000 shares for the nine months ended September 30, 2011 and 2010, respectively, were surrendered by our employees in connection with the vesting of restricted shares 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.
