Loss (income) per share

Basic (loss) income per share is computed by dividing net (loss) income by the weighted average number of common shares outstanding during the period, in addition to restricted stock units ("RSUs") and restricted common stock that are vested but

not

delivered. Diluted (loss) income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock are exercised or converted into common stock, and is calculated using the treasury stock method for stock options, restricted stock units, restricted stock, warrants and deferred common stock. Common equivalent shares are excluded from the calculation in loss periods, as their effects would be anti-dilutive.

For the

three

and

nine

months ended
