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 the first nine months of 2013, we made discretionary contributions of $2.1 million to the LTIP. Participants will receive a guaranteed return of 5.25% in 2013. We recognized compensation expense related to the LTIP as follows (in thousands):
|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2013 |  |  | 2012 |  |  | 2013 |  |  | 2012 |
Compensation expense |  | $ | 357 |  |  | $ | 299 |  |  | $ | 1,042 |  |  | $ | 876 |
As of September 30, 2013 and December 31, 2012, the balance due to participants was $6.3 million and $3.6 million, respectively, and was included as a component of other long-term liabilities in the Consolidated Balance Sheets.
