*  Calculation of fully diluted income per share for each of the six month periods 
is submitted in accordance with Securities Exchange Act of 1934 Release No. 9083, 
although it is contrary to paragraph 40 of APB Opinion No. 15 because it produces an 
antidilutive result, or is not required by footnote 2 to paragraph 14 of APB Opinion 
No. 15 because it results in dilution of less than 3%.
