Basic net loss per share is determined by dividing net loss by the weighted average shares of common stock outstanding during the period. Diluted net loss per share is determined by dividing net loss by diluted weighted average shares outstanding. Diluted weighted average shares reflects the dilutive effect, if any, of potentially dilutive common shares, such as common stock options calculated using the treasury stock method and convertible notes using the “if-converted” method. In periods with reported net operating losses, all common stock options are deemed anti-dilutive such that basic net loss per share and diluted net loss per share are equal.

The Company’s restricted shares are entitled to receive dividends and hold voting rights applicable to the Company’s common stock, irrespective of any vesting requirement. Accordingly, although the vesting commences upon the elimination of the contingency, the restricted shares are considered a participating security and the Company is required to apply the two-class method to consider the impact of the restricted shares on the calculation of basic and diluted earnings per share. The Company is currently in a net loss position and is therefore not required to present the two-class method; however, in the event the Company is in a net income position, the two-class method must be applied by allocating all earnings during the period to common shares and restricted shares.
