3.  Income (Loss) Per Share

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period plus dilutive common stock equivalents, using the treasury stock method.

Common stock equivalents for convertible preferred stock of 1,321,537 and 1,238,941 shares were excluded from the calculation of loss per share for the year ended December 31, 2014 and 2013, respectively because they were not dilutive; these shares would have been dilutive if the Company had not had a net loss for the this period.

Stock options for the purchase of 200,000 shares were excluded from the calculation of income per share for 2014, and a warrant for 30,000 shares was excluded from the calculation of income per share for 2013, respectively, because their effect was anti-dilutive.
