Net Income Per Common Share
Basic net income per common share attributable to Walmart is based on the weighted-average common shares outstanding during the relevant period. Diluted net income per common share attributable to Walmart is based on the weighted-average common shares outstanding during the relevant period adjusted for the dilutive effect of share-based awards. The Company did not have significant share-based awards outstanding that were antidilutive and not included in the calculation of diluted net income per common share attributable to Walmart for the three months ended April 30, 2017 and 2016.
The following table provides a reconciliation of the numerators and denominators used to determine basic and diluted net income per common share attributable to Walmart:
