Net Loss Per Share

Basic net loss per share is computed by dividing the net loss for the year by the weighted average number of common shares outstanding during the year. Diluted loss per share is calculated in accordance with the treasury stock method and reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted to common stock. Since the effect of the assumed exercise of common stock options, warrants and other convertible securities was anti-dilutive for all periods presented, basic and diluted loss per share are the same.

The following table summarizes potential common shares that were excluded from diluted net loss per share calculation because of their anti-dilutive effect:



	As of March 31,
	2014	2013
Options to purchase common stock	18,948,378	18,493,523
Warrants to purchase common stock	6,455,169	35,227,529
Convertible preferred stock	38,233	38,233
Total	25,441,780	53,759,285
