Compensation and Retirement Disclosure [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | Note 6. 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 over one to seven years depending 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 (dollars in thousands):
|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |
