NOTE 20. BASIC AND DILUTED NET EARNINGS PER SHARE

Basic net earnings per share has been computed using the weighted average number of Class A and Class B shares of common stock outstanding during the period. Diluted net earnings per share is computed using the weighted average number of shares of Class A and Class B common stock outstanding during the period plus the dilutive effects of stock options.

Options to purchase 1,830,222 and 1,443,087 shares of Class A common stock were outstanding at March 31, 2019 and 2018, respectively. Diluted weighted average shares outstanding exclude outstanding stock options whose exercise price is in excess of the average price of the company’s stock price. These options are excluded from the respective computations of diluted net income or loss per share because their effect would be anti-dilutive. As of March 31, 2019 and 2018 there were 7,195 and 133,352 dilutive shares, respectively.
