14. NET LOSS PER COMMON SHARE | Basic loss per share excludes dilution and is computed by dividing net loss by the weighted average of common shares outstanding for the period. Diluted loss per share reflects the potential dilution that could occur if securities or other common stock equivalents (convertible preferred stock, convertible debt, warrants to purchase common stock and common stock options) were exercised or converted into common stock. The following table provides a reconciliation of the numerators and denominators of the basic and diluted per-share computations:
|  | 2013 |  |  | 2012 |  |  | 2011 |
Net loss – available to common shareholders |  | $ | (9,230,478 | ) |  | $ | (17,645,930 | ) |  | $ | (26,780,712 | )
Less: Gain on derivative instruments |  |  | (10,750,666 | ) |  |  | (1,911,683 | ) |  |  | (4,199,256 | )
Net loss - diluted |  | $ | (19,981,144 | ) |  | $ | (19,557,613 | ) |  | $ | (30,979,968 | )
Weighted average number of shares - basic and diluted |  |  | 30,279,442 |  |  |  | 25,183,654 |  |  |  | 20,848,899 |
Loss per share - basic |  | $ | (0.30 | ) |  | $ | (0.70 | ) |  | $ | (1.28) |
Loss per share - diluted |  | $ | (0.66 | ) |  | $ | (0.78 | ) |  | $ | (1.49 | )
Excluded from the above computations of weighted-average shares for diluted net loss per share were options and warrants to purchase 43,791, 907,301 and 2,535,371 shares of common stock as of September 30, 2013, 2012 and 2011, respectively. These securities were excluded because their inclusion would have an anti-dilutive effect on net loss per share diluted.
