Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Stock-Based and Other Compensation Plans The Company grants stock options, stock appreciation rights (“SARs”), long-term incentive plan performance-based awards, and time-based restricted shares, some of which are cash-settled awards with the final payment indexed to the percentage change in the Company’s stock price from the date of grant. For the three and nine months ended September 30, 2016, the Company recognized stock-based compensation expense of $1.1 million and $6.5 million, respectively, inclusive of $0.4 million of mark-to-market gain and $1.0 million of mark-to-market expense on awards indexed to the Company's stock price. For the three and nine months ended September 30, 2015, the Company recognized stock-based compensation expense of $0.1 million and $3.4 million, respectively, inclusive of $1.1 million and $0.2 million of mark-to-market gains on awards indexed to the Company's stock price. As of September 30, 2016, there was $10.9 million of unrecognized compensation expense related to these awards. The remaining compensation expense for the stock options, SARs and restricted awards is expected to be recognized over a weighted-average period of approximately two years, and the remaining expense for long-term incentive plan performance-based awards will be recognized within approximately one year. The Company also has deferred compensation plans for its Board of Directors and certain executives. Under these plans, participants can elect to invest their deferrals in the Company’s common stock. In the fourth quarter of 2015, the executive deferred compensation plan was terminated. All amounts due under the executive deferred compensation plan will be distributed to plan participants during 2016. At both September 30, 2016 and 2015, the number of common shares deferred under these plans was 0.1 million. As these awards can be settled in cash, the Company records compensation costs each period based on the change in the Company’s stock price. For the three and nine months ended September 30, 2016, the Company recognized a benefit of $0.2 million and expense of $0.1 million, respectively, related to these awards. For the three months ended September 30, 2015, the Company recognized a benefit of $0.2 million related to these awards. For the nine months ended September 30, 2015, the Company recognized nominal expense.
