| Earnings Per Share [Text Block]   | Earnings (Loss) per ShareThe following data shows the amounts used in computing (loss) earnings per share and the effect on income and the weighted average number of shares of dilutive potential common shares.

The outstanding shares used to calculate the weighted average basic shares excludes 283,596 and 241,412 of restricted shares and performance shares at September 30, 2013 and 2012, respectively, as these shares were issued but were not vested and, therefore, not considered outstanding for purposes of computing basic earnings per share at the balance sheet dates.  Diluted earnings (loss) per share includes the effect of all potentially dilutive securities on earnings per share.  We have stock options, stock-settled appreciation rights ("SSARs") and unvested restricted shares that are potentially dilutive securities. When a loss is reported, the denominator of diluted earnings per share cannot be adjusted for the dilutive impact of share-based compensation awards because doing so would be anti-dilutive.  In addition, when a loss from continuing operations is reported, adjusting the denominator of diluted earnings per share would also be anti-dilutive to the loss per share, even if the entity has net income after adjusting for a discontinued operation.  Therefore, for all periods presented, basic weighted-average shares outstanding were used in calculating the diluted net loss per share. |
