Net Loss Per Share

9 Months Ended

Sep. 30, 2014

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and dilutive common share equivalents outstanding for the period, determined using the treasury-stock method.

The basic and diluted net loss per share amounts for the three and nine months ended September 30, 2014 and 2013 were computed based on the shares of common stock outstanding during the respective periods. Potentially dilutive securities excluded from the diluted loss per share calculation are as follows:



	September 30,
	2014	2013
Outstanding options to purchase common stock	6,779,998	6,909,332
Warrants to purchase common stock	604,327	609,016
Total	7,384,325	7,518,348
