An annual report of Ford Motor Company states: "Net income a share is computed based upon the average number of shares of capital stock of all classes outstanding. Additional shares of common stock may be issued or delivered in the future on conversion of outstanding convertible debentures, exercise of outstanding employee stock options, and for payment of defined supplemental compensation. Had such additional shares been outstanding, net income a share would have been reduced by 10¢ in the current year and 3¢ in the previous year. .As a result of capital stock transactions by the company during the current year (primarily the purchase of Class A Stock from Ford Foundation), net income a share was increased by 6¢."
