2. Earnings Per Share

We compute basic earnings per share by dividing net earnings available to common stockholders by the actual weighted average number of common shares outstanding for the reporting period. Diluted earnings per share reflects the potential dilution that could occur if holders of unvested restricted and performance share units converted their holdings into common stock. The dilutive effect of restricted and performance share units was 1.1 million shares during the three and nine months ended September 30, 2020, compared to 1.0 million shares during the three and nine months ended September 30, 2019.
