Net Loss Per Share

Net Loss Per Share

Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The weighted-average number of shares of common stock outstanding does not include any potentially dilutive securities or any unvested restricted shares of common stock. These unvested restricted shares, although classified as issued and outstanding at March 31, 2017 and 2016, are considered contingently returnable until the restrictions lapse and will not be included in the basic net loss per share calculation until the shares are vested. Unvested shares of our restricted stock do not contain non-forfeitable rights to dividends and dividend equivalents. Unvested restricted stock units are not included in calculations of basic net loss per share, as they are not considered issued and outstanding at time of grant.

Diluted net loss per share is computed by giving effect to all potential shares of common stock, including stock options, preferred stock, restricted stock units, and unvested restricted stock awards, to the extent they are dilutive. For the three months ended March 31, 2017 and 2016, all such common stock equivalents have been excluded from diluted net loss per share as the effect to net loss per share would be anti-dilutive (decrease our net loss per share).

The following table sets forth the computation of the Company’s basic and diluted net loss per share (in thousands, except per share data):

	Three Months Ended March 31,

The following table represents the potential shares that were excluded from the computation of weighted-average number of shares of common stock in computing the diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect (in thousands):

	Three Months Ended March 31,
	2017	2016
Unvested restricted stock units	2,938	3,145
Vested restricted stock units	517	—
Unvested restricted stock awards	354	363
Outstanding stock options	1,222	1,250
Shares of common stock issuable upon conversion of preferred stock, Series A-2	79	79
