Earnings Per Share [Abstract] |
Earnings Per Share | Note 16. Earnings Per Share Basic earnings (loss) per common share (“EPS”) are generally calculated as income (loss) available to common shareholders divided by the weighted average number of common shares outstanding. Diluted EPS is generally calculated as income (loss) available to common shareholders divided by the weighted average number of common shares outstanding plus the dilutive effect of common share equivalents. The calculation of basic and diluted EPS for the years ended October 31, 2016, 2015 and 2014 was as follows:
|  | 2016 |  | 2015 |  | 2014
Numerator |  |  |  |  |  |
Net loss |  | $ | (51,208 | ) |  | $ | (29,684 | ) |  | $ | (38,883 | )
Net loss attributable to noncontrolling interest |  | 251 |  |  | 325 |  |  | 758 |
Preferred stock dividend |  | (3,200 | ) |  | (3,200 | ) |  | (3,200 | )
Net loss attributable to common shareholders |  | $ | (54,157 | ) |  | $ | (32,559 | ) |  | $ | (41,325 | )
Denominator |  |  |  |  |  |
Weighted average basic common shares |  | 29,773,700 |  |  | 24,513,731 |  |  | 20,473,915 |
Effect of dilutive securities (1) |  | — |  |  | — |  |  | — |
Weighted average diluted common shares |  | 29,773,700 |  |  | 24,513,731 |  |  | 20,473,915 |
Basic loss per share |  | (1.82 | ) |  | (1.33 | ) |  | (2.02 | )
Diluted loss per share (1) |  | (1.82 | ) |  | (1.33 | ) |  | (2.02 | )
(1) | Due to the net loss to common shareholders in each of the years presented above, diluted earnings per share was computed without consideration to potentially dilutive instruments as their inclusion would have been antidilutive. At October 31, 2016 and 2015, potentially dilutive securities excluded from the diluted loss per share calculation are as follows:
| October 31, 2016 |  | October 31, 2015
July 2016 Offering - Series A Warrants | 7,680,000 |  |  | — |
July 2016 Offering - Series B Warrants | 3,826,000 |  |  | — |
July 2014 Offering - NRG Warrants | 166,666 |  |  | 166,666 |
Outstanding options to purchase common stock | 246,923 |  |  | 257,769 |
Unvested RSAs | 915,831 |  |  | 450,783 |
5% Series B Cumulative Convertible Preferred Stock (2) | 454,043 |  |  | 454,043 |
Series 1 Preferred Shares to satisfy conversion requirements (2) | 1,042,000 |  |  | 337,200 |
Total potentially dilutive securities | 14,331,463 |  |  | 1,666,461 |
