(1)  The  results  for 1995 reflect a $134 million pretax credit  primarily
     from  settlement gains resulting from lump sum pension  payments  from
     the  pension  plan to former employees who left the  business  in  the
     nonmanagement  work  force  restructuring,  partially  offset  by  $74
     million  associated  with  increased  force  costs  related   to   the
     restructuring  started  in  1994, as well  as  a  $58  million  charge
     recorded  to  write  down  certain data processing  equipment  to  net
     realizable  value.   Results for 1994 reflect a  $728  million  pretax
     charge  associated  with the nonmanagement work  force  restructuring.
     Costs of the work force restructuring program have largely been funded
     from the Ameritech Pension Plan.
     
(2)  Earnings are income before income taxes and fixed charges.  Since  the
     Michigan Single Business Tax ("the Tax") and rental expense have  been
     deducted,  the  Tax  and  the  one-third  portion  of  rental  expense
     considered to be fixed charges are added back.
     
(3)  For  purposes  of  above  computation, the  preferred  stock  dividend
     requirement  of  a  subsidiary  has  been  increased  to   an   amount
     representing the pretax earnings which would be required to cover  the
     dividend requirements.
