Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per ShareBasic net (loss) income per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, excluding the dilutive effects of restricted stock. Diluted net (loss) income per share of common stock is computed by dividing the net (loss) income attributable to common stockholders by the sum of the weighted-average number of shares of common stock outstanding during the period plus the potential dilutive effects of restricted stock outstanding during the period calculated in accordance with the treasury stock method, although restricted stock is excluded if their effect is anti-dilutive. Because the impact of these items is anti-dilutive during periods of net loss, there was no difference between basic and diluted net loss per share of common stock for the three and nine months ended September 30, 2021. Because their effect would be anti-dilutive, 2,237 shares of common stock underlying equity-based awards were excluded from the calculation of diluted earnings per share for both three and nine months ended September 30, 2020. There is no reconciliation between weighted average common shares outstanding and diluted weighted average shares of common stock outstanding for any period presented.
