EARNINGS PER SHARE

Basic earnings per share excludes the dilutive effect of common shares that could potentially be issued due to the exercise of stock options and vesting of unvested restricted stock and restricted stock units, and is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. At March 31, 2019 and 2018, the Company had restricted stock, restricted stock units and stock options, which could potentially dilute basic earnings per share in the future. The following table sets forth the reconciliation from basic to dilutive average common shares (in millions, except shares which are in thousands):
