* The assumed exercise of stock options reflected by these adjustments has no
  effect on Class E or Class H common stock earnings per share, because to the
  extent that shares of Class E or Class H common stock deemed to be outstanding
  would increase, such increased shares would also increase the numerator of the
  fraction used to determine Available Separate Consolidated Net Income.
