Earnings Per Share (Notes)

3 Months Ended

Mar. 31, 2020

Basic net (loss) income per share of common stock is computed by dividing net (loss) income 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 income per share of common stock is computed by dividing the net 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 diluted net loss per share of common stock for the three months ended March 31, 2020 . The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share as their effect would be anti-dilutive was 2,477 and 978 for the three months ended March 31, 2020 and 2019, respectively. The following table reconciles the weighted-average common shares outstanding used in the calculation of basic net (loss) income per share to the weighted average common shares outstanding used in the calculation of diluted net income per share.
