Note 9. Net Loss per Share
  
Basic net loss per share is computed by dividing net loss for the period by the weighted average shares of common stock outstanding during each period. Diluted net loss per share is computed by dividing net loss for the period by the weighted average shares of common stock, common stock equivalents and potentially dilutive securities outstanding during each period. The Company uses the treasury stock method to determine whether there is a dilutive effect of outstanding option grants.
  
The following table sets forth the computation of the Company’s basic and diluted net loss per share for the periods presented:
