Net Earnings Per Share

NOTE D – EARNINGS PER SHARE

Basic earnings per share is based on the weighted average number of common shares and participating securities outstanding during the period.  Diluted earnings per share also includes the dilutive effect of additional potential common shares issuable.  Unvested stock awards, which contain non-forfeitable rights to dividends whether paid or unpaid (“participating securities”), are included in the number of shares outstanding for both basic and diluted earnings per share calculations.
