Basic earnings per share is computed by dividing net earnings attributable to common shares by the weighted average number of common shares outstanding for the period. Diluted net earnings per share include the potential dilution of securities that could participate in our earnings, but not securities that are anti-dilutive.

The following table provides a reconciliation of the numerators and denominators used to calculate basic and diluted net earnings per common share as disclosed in our consolidated statements of operations for the fiscal years ended March 31, 2021, 2020 and 2019 (in thousands, except per share data).
