Net Income (Loss) per Share Attributable to Common Stockholders

8.	Net Income (Loss) Per Share Attributable to Common Stockholders

The dilutive effect of outstanding stock options and warrants is calculated using the treasury stock method. Stock options and warrants are anti-dilutive and excluded from the diluted net income (loss) per share calculation if the exercise price exceeds the average market price of the common shares.

Potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows:

	Six Months Ended June 30,

Common stock warrants		85		85
