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 1,101,281 shares were excluded from the calculation of loss per share for the nine months and three months ended September 30, 2014, because they were anti-dilutive.
