Net (Loss) Income per Share

16. Net (Loss) Income per Share

Net (loss) income per share has been computed using the weighted average number of shares of common stock outstanding during each period. Diluted amounts per share include the impact of the Company’s outstanding potential common shares, such as shares issuable upon exercise of in-the-money stock options or warrants, when dilutive. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net (loss) income per common share.

The following table sets forth the components of the computation of basic and diluted net (loss) income per common share for the periods indicated:
