Loss Per Share

Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. The weighted-average number 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, 2015 and 2014, are considered contingently returnable until the restrictions lapse and will not be included in the basic earnings 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 loss per share, as they are not considered issued and outstanding at time of grant.

Diluted loss per share includes the effect of all potentially dilutive securities on earnings per share. The difference between basic and diluted weighted average shares outstanding was the dilutive effect of unvested restricted stock, unvested restricted stock units, stock options, and preferred stock. For the three months ended March 31, 2015 and 2014, diluted net loss per share is the same as basic net loss per share due to the Company's net loss attributable to common stockholders and the potential shares of common stock that could have been issuable have been excluded from the calculation of diluted net loss per share because the effects, as a result of our net loss attributable to common stockholders, would be anti-dilutive.

The following table represents a reconciliation of the basic and diluted earnings per share computations contained in our condensed consolidated financial statements (in thousands, except per share data):

The weighted average diluted shares of common stock outstanding for the three months ended March 31, 2015 excludes the effect of 1,300,000 out-of-the-money options, because their effect would be anti-dilutive.
