Net Income Per Share of Common Stock [Abstract]
Net Income Per Share of Common Stock	– Net Income/(Loss) Per Share of Common StockBasic net income/(loss) per share is based on the weighted average number of shares of common stock outstanding during the period, which does not include unvested restricted common stock subject to forfeiture of 3,630,000 shares for the period ended June 30, 2021, compared to 4,483,000 shares for the period ended June 30, 2020. Diluted net income per share reflects: (a) the potential dilution assuming shares of common stock were issued upon the exercise of outstanding in-the-money options and the assumed proceeds, which are deemed to be the proceeds from the exercise plus compensation cost not yet recognized attributable to future services using the treasury method, were used to purchase shares of the Company’s common stock at the average market price during the period, and (b) the vesting of granted non-vested restricted stock awards for which the assumed proceeds upon vesting are deemed to be the amount of compensation cost not yet recognized attributable to future services using the treasury stock method, to the extent dilutive. For the three and six months ended June 30, 2021, options to purchase approximately 13,000 and 2,000 shares of common stock, respectively, have been excluded from the calculation of diluted net income per share as compared to approximately 8,000 and 180,000 shares that were excluded from the calculation of diluted net loss per share for the three and six months ended June 30, 2020, as the result would have been anti-dilutive. For the three and six months ended June 30, 2021, approximately 0 and 8,000 restricted shares, respectively, were excluded from the calculation of diluted net income per share as compared to approximately 2,477,000 and 2,532,000 shares that were excluded from the calculation of diluted net loss per share for the three and six months ended June 30, 2020, as the result would have been anti-dilutive. Shares underlying contingently issuable awards that have not met the necessary conditions as of the end of a reporting period are not included in the calculation of diluted net income (loss) per common share for that period. The Company had contingently issuable performance awards outstanding that did not meet the performance conditions as of June 30, 2021 and 2020 and, therefore, were excluded from the calculation of diluted net income/ (loss) per common share for the three and six months ended June 30, 2021 and 2020. The maximum number of potentially dilutive shares that could be issued upon vesting for these performance awards was approximately 17,000 and 300,000 as of June 30, 2021 and 2020, respectively. These amounts were also excluded from the computation of weighted average potentially dilutive securities.
