Earnings Per Share

NOTE B – EARNINGS PER SHARE

Earnings per share was calculated using the two-class method, which is an earnings allocation formula that determines earnings per share for common shareholders and each participating security according to dividends declared and participation rights in undistributed earnings. Basic earnings per share is based on the weighted average number of common shares outstanding during the period. Diluted earnings per share also includes the dilutive effect of additional potential common shares issuable under the Company's stock-based Incentive Compensation Plan, which are determined using the treasury stock method.
