(3) EARNINGS PER SHARE

Basic earnings per share are computed by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding and the number of dilutive potential common share equivalents during the period, calculated using the treasury-stock method for outstanding stock options.

The calculation of basic and diluted earnings per share for the three and nine months ended September 30, 2019 and 2018 are as follows (in thousands, except per share data):
