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 March 2013, we made a discretionary contribution of $2.0 million to the LTIP. Participants will receive a guaranteed return of 5.25% in 2013. We recognized compensation expense related to the LTIP of $0.4 million and $0.7 million, respectively, for the three and six months ended June 30, 2013 and $0.3 million and $0.6 million, respectively, for the three and six months ended June 30, 2012. As of June 30, 2013 and December 31, 2012, the balance due to participants was $5.2 million and $3.6 million, respectively, and was included as a component of other long-term liabilities in the Consolidated Balance Sheets.
