Earnings Per Share [Text Block] | 12. Basic earnings per share is computed by dividing net income or (loss) (the “numerator”) by the weighted-average number of common shares, adjusted for non-vested shares of restricted stock (the “denominator”) for the period. The basic weighted-average number of shares includes 13.6 million shares related to Purchase Contracts which are contingently issuable with no additional cash required to be paid. Computing diluted earnings per share is similar to computing basic earnings per share, except that the denominator is increased to include the dilutive effects of options and non-vested shares of restricted stock. Any options that have an exercise price greater than the average market price are considered to be anti-dilutive and are excluded from the diluted earnings per share calculation. For the three and nine months ended July 31, 2011, 0.1 million and 0.4 million, respectively, of incremental shares attributed to non-vested stock and outstanding options to purchase common stock were excluded from the computation of diluted EPS because we had a net loss for the period, and any incremental shares would not be dilutive. In addition, shares related to out-of-the money stock options that could potentially dilute basic EPS in the future that were not included in the computation of diluted EPS were 5.7 million and 3.5 million at July 31, 2011 and 2010, respectively, because to do so would have been anti-dilutive for the periods presented. For the three months ended July 31, 2010, 1.3 million incremental shares attributed to non-vested stock and outstanding options to purchase common stock were excluded from the computation of diluted EPS because we had a net loss for the period, and any incremental shares would not be dilutive. For the nine months ended July 31, 2010, diluted earnings per common share was computed using the weighted average number of shares outstanding adjusted for the 1.0 million incremental shares attributed to non-vested stock and outstanding options to purchase common stock.
