ITEM 5. OTHER EVENTS.


On May 29, 2002,  Moody's Investors Service  ("Moody's")  lowered its ratings of
long-term  debt  issued  or  guaranteed  by AT&T to Baa2 from A3.  Moody's  also
confirmed AT&T's short-term rating as Prime-2.  Moody's ratings outlook for AT&T
remains  negative  but  AT&T is not  currently  on  review  for  any  additional
downgrade by Moody's.  On June 3, 2002,  Fitch  Ratings also  downgraded  AT&T's
long-term debt rating to BBB+ from A-, with the rating remaining on Rating Watch
Negative pending  completion of the AT&T Comcast  transaction.  AT&T's long-term
debt ratings remain BBB+ and CreditWatch with negative  implications by Standard
& Poor's  Ratings Group  ("Standard & Poor's").  Further  ratings  actions could
occur at any time.

Any downgrade by either Standard & Poor's or Moody's  increases,  by one-quarter
of one percent (0.25%) for each ratings notch  downgraded by either agency,  the
interest rates paid by AT&T on  approximately  $10.1 billion of long-term  debt,
which would increase AT&T's interest costs by approximately $25 million per year
for each such ratings notch downgrade by either rating agency. As a result,  the
Moody's  downgrade  referred  to above will  increase by one-half of one percent
(.50%)  the  interest  rates  paid by AT&T on  approximately  $10.1  billion  of
long-term debt, which will increase AT&T's interest costs by  approximately  $50
million per year. Any ratings downgrade by Standard & Poor's would also increase
such interest costs by one-quarter of one percent (0.25%) for each ratings notch
downgrade.

In  addition  to the  increased  interest  costs on the $10.1  billion  offering
referred  to above,  AT&T could  incur  increased  costs in the  replacement  or
renewal of its credit facility and  refinancings of  approximately $5 billion of
debt through March 31, 2003.  Assuming current market conditions and assumptions
regarding  the type of  financing  available,  the  additional  annualized  cost
increases could approximate $100 million, although it is not possible to predict
the actual  amount of any such  interest  cost  increase as a result of a rating
notch downgrade.  Additional ratings downgrades could result in greater interest
rate increases for each notch downgrade. In addition,  interest expense could be
higher in  subsequent  periods than it otherwise  would have been as  additional
maturing  debt is replaced by debt with higher  interest rate spreads due to the
lower credit ratings. Also, in addition to interest rates, differences in credit
ratings affect the amounts of  indebtedness,  types of financing  structures and
debt markets that may be available to AT&T.

As a result of the Moody's  downgrade,  AT&T will seek to replace or renegotiate
all or a portion of its $8 billion  364-day term bank  facility  that expires in
December 2002,  since the facility (under which no amounts are currently  drawn)
currently  provides  among other things that AT&T could not  consummate the AT&T
Comcast  transaction  unless after giving effect thereto  AT&T's  long-term debt
would be rated at least Baa1 by Moody's.  In this  regard,  AT&T is currently in
discussions  with respect to a substitute  facility  with a group that  includes
affiliates of certain members of the  underwriting  syndicate for AT&T's pending
equity offering, although there are no assurances with respect to the success of
such negotiations.



Also,  AT&T is a party to an  approximately  $200 million  lease that contains a
provision  comparable to that set forth in the 364-day term bank facility.  As a
result,  AT&T will be required to either  renegotiate the terms of that lease or
repay the lessor thereunder.

As previously  disclosed,  on May 10, 2002,  AT&T Broadband Group filed a demand
for  arbitration  against CSG  Systems,  Inc.  before the  American  Arbitration
Association.  On May 30, 2002, CSG answered and submitted  counterclaims against
AT&T Broadband.
