| Compensation and Employee Benefit Plans [Text Block]          | EMPLOYEE BENEFIT PLANS We sponsor a qualified retirement plan covering substantially all of our employees. The plan consists of both a traditional and a Roth 401(k) component, as well as a profit sharing component. The 401(k) components enable eligible employees to contribute a portion of their compensation through payroll deductions in accordance with specific guidelines. We provide a discretionary matching contribution based on a percentage of the employees' contributions up to certain limits. Our contribution to the profit sharing component is discretionary. Our total combined expense for the plan was$4.9 million, $3.9 million and $3.7 millionfor 2015, 2014 and 2013, respectively. We provide a supplemental retirement benefit of deferred compensation under terms of the various employment agreements with certain former executive officers. Expenses related to this plan are charged to general and administrative expenses and the related costs were immaterial in 2015, 2014 and 2013. As of December 31, 2015 and 2014, the liability related to this benefit was $1.3 million and $1.5 million, respectively, which was included in other liabilities on the consolidated balance sheets, with the exception of $0.3 million included in other accrued expenses as of December 31, 2015 and 2014. We provide a supplemental health care benefit covering certain former executive officers and their spouses in accordance with each officer's employment agreement. Expenses incurred during 2015, 2014 and 2013 related to this plan were immaterial. As of December 31, 2015 and 2014, the related liability of $0.8 million and $0.7 million, respectively, is included in other liabilities on the consolidated balance sheets. We maintain a non-qualified deferred compensation plan for our non-employee directors. The amount of compensation deferred by each participant is based on participant elections. The amounts deferred pursuant to the plan are invested in our common stock, maintained in a rabbi trust and are classified in the consolidated balance sheets as treasury shares as a component of shareholders' equity. The plan may be settled in either cash or shares as requested by the participant.
