Compensation and Retirement Disclosure [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | (9) 401(k) Profit Sharing, Deferred Compensation and Long-term Incentive Plans We have a defined contribution 401(k) plan and trust covering substantially all full-time employees. The annual contribution to the plan is at the discretion of our Board of Directors. Contributions of $2.1 million, $1.9 million and $1.7 million were recognized for the years ended December 31, 2013, 2012 and 2011, respectively. Employees may contribute to the plan if they meet certain eligibility requirements. We offer a deferred compensation and long-term incentive plan (the “LTIP”) to provide certain employees the ability to accumulate assets for retirement on a tax deferred basis. We may make discretionary contributions to the LTIP. Discretionary contributions vest between one and seven years based on the employee’s age and position. Additionally, a participant may defer a portion of his or her compensation and receive the deferred amount upon certain events, including termination or retirement. The following is a summary related to our LTIP:
