NET LOSS PER SHARE

8.             NET LOSS PER SHARE

We compute basic net loss per share by dividing net loss attributable to our common stockholders by the weighted average number of shares of common stock outstanding during the period. We exclude all outstanding options and unvested restricted stock as such securities are anti-dilutive for all periods presented.

Basic and diluted net loss per share is calculated as follows (in thousands, except per share amounts):
