| 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$4.8 million, $4.9 million, and $3.9 millionfor 2016, 2015, and 2014, respectively. |
