Earnings Per Share

Basic EPS is computed based on the weighted average number of shares of common stock outstanding. Diluted EPS is computed based on the weighted average number of common shares outstanding increased by dilutive common stock equivalents, attributable to stock option awards, restricted stock awards, restricted stock unit awards and redeemable convertible preferred stock outstanding. Due to the net loss for the three months ended March 31, 2014 and 2013, all common stock equivalents, totaling 16,749,848 and 10,994,077, respectively, were excluded from diluted net loss per share because they were anti-dilutive.  The common stock equivalents consist of 7,968,332 of outstanding stock option and restricted stock awards and 8,781,516 related to outstanding redeemable convertible preferred stock for the three months ended March 31, 2014 and 10,994,077 of outstanding stock option and restricted stock awards for the three months ended March 31, 2013.

The following represents a reconciliation of the numerators and denominators of the basic and diluted EPS computation:
