Item 7.01.  REGULATION FD DISCLOSURE

Our Senior  Executive  Vice  President and Chief  Financial  Officer,  Thomas W.
Horton,  on  December 9, 2004 made a  presentation  at the Credit  Suisse  First
Boston Media & Telecom Week Conference which included the following  disclosures
about our company:

Consumer Services

We believe that the Consumer  business will continue to deliver  strong  margins
and cash flow for the foreseeable future.

With our decision to stop competing in the traditional Consumer services market,
the revenue  decline will increase.  But this business will continue to generate
strong operating margins as we realize cost savings  associated with our reduced
marketing  efforts.  Margins  will  also  benefit  by  the  optimization  of our
supporting  infrastructure  that we've put in place and by putting an end to the
costly regulatory battles we've been engaged in for several years now. And based
on our observations  thus far, we anticipate  Consumer  operating margins in the
fourth quarter of 2004 to be a bit over 20%.

Business Services

Overall we are  encouraged  by the progress  we've made in the large  enterprise
segment of the market and expect to see ongoing  improvement  in this area going
forward.  But this progress  will be offset by the negative  trends in wholesale
and small business in the near term.

-Large Business

The large or "enterprise"  market  represents about 65% of our business revenue.
Our company is in a unique  position to serve these large  enterprise  customers
with a  superior  product  set and  customer  relationships  and we are  already
beginning to see signs of share improvement.

-Wholesale

The wholesale market  represents about 20% of our overall business  revenue.  We
expect that continued  pricing pressure in wholesale will negatively impact both
voice and data revenue, despite continued volume strength.

-Small and Medium Business

Small and medium business  represents about 15% of our business  revenue.  We're
adjusting  our  strategy  to be more  selective  in our  approach  to the  small
business market.  Specifically,  we'll focus more on profitability  than overall
share at the low end of the market,  which will significantly  impact revenue in
this area - mainly  impacting  local voice revenue.  In fact, we expect that the
local  voice  revenue  growth rate will be  significantly  negative in 2005 as a
result of our changed focus in this area.

Cost Reduction

We now believe  we're on track to  significantly  exceed our  operating  expense
reduction  target of $3 billion by the end of 2005. In fact,  we'll have already
achieved a $2.5 billion reduction by the end of 2004.


Financial

We  previously  said we expect to be around $4.8  billion  EBITDA  less  capital
expenditures  for the year - and based on where we are to date will  likely be a
little better than that target.
