NOTE
H
: EARNINGS PER SHARE
Basic earnings per share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by adjusting the weighted average number of shares of common stock outstanding by common stock equivalents attributable to dilutive stock options. The computation of diluted earnings per share does
not
assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect on earnings per share. The computations of basic and diluted earnings per share were as follows:
