|Earnings Per Share [Abstract]|
|Schedule of Earnings Per Share, Basic and Diluted [Table Text Block]||
(1) For the three and six months ended June 30, 2017 and 2016, respectively, all common shares potentially issuable in connection with outstanding restricted stock unit awards have been excluded from the calculation of diluted EPS as the company incurred losses during the periods, therefore, inclusion of such potential common shares would be anti-dilutive.
(2) Weighted average common shares issuable upon the assumed conversion of our Mandatory Convertible Preferred Stock totaling 23,809,500 shares were excluded from the computation of diluted EPS as such shares would be anti-dilutive.
Tabular disclosure of an entity's basic and diluted earnings per share calculations, including a reconciliation of numerators and denominators of the basic and diluted per-share computations for income from continuing operations.
