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