ITEM 9. REGULATION FD DISCLOSURE.

What are we disclosing?

On June 4, 2003,  David W. Dorman,  our Chairman  and Chief  Executive  Officer,
disclosed at the Sanford Bernstein Strategic Decisions  Conference that our Free
cash flow for the quarter  ended March 31, 2003 was $1.4  billion.  By Free cash
flow we mean Net cash provided by operating activities of continuing  operations
(which we reported as $2,216 million in our Consolidated  Statement of Cash Flow
included in Form 10-Q for the quarter  ended March 31, 2003) minus cash paid for
Capital  expenditures  and other additions (which we reported as $859 million in
our  Consolidated  Statement of Cash Flow  included in Form 10-Q for the quarter
ended March 31, 2003).  Mr. Dorman also stated that our Operating margin for the
twelve-month  period  ended  March 31,  2003 was 13.2%.  This  operating  margin
excludes a $1,029 million charge recorded in the fourth quarter of 2002 relating
to AT&T Latin America.  Operating  margin is calculated as operating  income for
the twelve month period  ($4,922  million which  excludes the AT&T Latin America
charge),  as a  percentage  of Revenue  for the  twelve  month  period  ($37,265
million).  Without  the  adjustment  for the  AT&T  Latin  America  charge,  our
Operating margin for the twelve-month period ended March 31, 2003 was 10.4%. Our
senior  management  believes  that these  financial  measures  are  relevant  in
assessing our liquidity and financial performance.

This information  furnished under "Item 9. Regulation FD Disclosure" is intended
to be furnished  under "Item 12. Results of Operations and Financial  Condition"
in accordance with SEC Release No. 33-8216.
