Compensation and Retirement Disclosure [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | Note 7. Deferred Compensation and Long-Term Incentive Plan 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. In January 2014, we made a discretionary contribution of $2.1 million to the LTIP. Participants will receive a guaranteed return of 5.25% in 2014. We recognized compensation expense related to the LTIP as follows (in thousands):
|  | Three Months Ended March 31, |
|  | 2014 |  |  | 2013 |
Compensation expense |  | $ | 700 |  |  | $ | 334 |
As of March 31, 2014 and December 31, 2013, the balance due to participants was $8.5 million and $7.1 million, respectively, and was included as a component of other long-term liabilities in the Consolidated Balance Sheets.
