The Company has granted stock compensation awards with nonforfeitable dividend rights which are considered participating securities. Earnings per share is calculated using the two-class method, as such awards are more dilutive under this method than the treasury stock method. Basic earnings per share is calculated by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding during the period, which excludes the participating securities. Diluted earnings per share includes the dilutive effect of additional potential common shares from stock compensation awards. Earnings per share have been computed based on the following weighted average number of common shares outstanding:

	Three months ended September 30, (In thousands, except per share amounts)						Six months ended September 30, (In thousands, except per share amounts)

Diluted earnings per share do not include the effect of certain stock options as their impact would be anti-dilutive. For the three months ended September 30, 2019 and 2018, potential shares of common stock from stock options totaling 58,400 and 79,600, respectively, were not included in the diluted earnings per share calculation because their effect is anti-dilutive. For the six months ended September 30, 2019 and 2018, potential shares of common stock from stock options totaling 83,600 and 79,600, respectively, were not included in the diluted earnings per share calculation because their effect is anti-dilutive.
