ITEM 1. BUSINESS.

GENERAL

                  AT&T Corp.  ("AT&T" or the "Company") was incorporated in 1885
under the laws of the State of New York and has its principal  executive offices
at 32 Avenue of the Americas,  New York, New York 10013-2412  (telephone  number
212-387-5400).Internet  users can access information about AT&T and its services
at http://www.att.com.

                  AT&T is among the world's  communications  leaders,  providing
voice, data and video telecommunications services to large and small businesses,
consumers and government  entities.  AT&T and its subsidiaries furnish regional,
domestic,  international and local communication  services.  AT&T's wholly owned
subsidiaries, including AT&T Wireless Services, Inc., provide cellular telephone
and other wireless services. AT&T also provides billing,  directory, and calling
card services to support its communications business.

DEVELOPMENT OF BUSINESS

                  During 1996 AT&T  separated its business  into three  publicly
held  stand-alone  companies:  the current AT&T,  focused on  communication  and
information   services,   Lucent   Technologies  Inc.   ("Lucent")   focused  on
communications  systems and technology and NCR  Corporation  ("NCR")  focused on
transaction-intensive  computing. AT&T distributed to its shareowners all of the
shares AT&T owned of Lucent on  September  30, 1996 and all of the shares of NCR
on December 31, 1996.

                    Following  the  separation,  AT&T  has  focused  on its core
business  and  disposed of assets and  businesses  that were not  strategic.  In
October 1996,  AT&T completed the sale of its majority  interest in AT&T Capital
Corporation  (leasing services  business) in which AT&T received $1.8 billion in
cash. In 1997,  AT&T  completed the sales of AT&T Skynet  (satellite  services),
AT&T Tridom (satellite data and video communications services) and its submarine
systems   business.   In  addition,   AT&T  sold  its  investments  in  DirectTV
(direct-broadcast  television service and DSS equipment  business) and decreased
its  investment  in Smartone  Communications  (a wireless  joint venture in Hong
Kong).

                  In addition,  in 1997, AT&T agreed to sell AT&T Universal Card
Services, Inc.(credit card services business), American Transtech Inc. (customer
care  services),  its  investment  in  LIN  Television  Corporation  (commercial
television broadcasting) and WOOD-TV (AT&T's television station in Grand Rapids,
Michigan).

                  On January 8, 1998,  AT&T  entered  into a  definitive  merger
agreement with Teleport Communications Group, Inc. ("TCG"). The merger with TCG,
which remains subject to regulatory  approvals and a number of other conditions,
is expected to close mid to late 1998. Under the merger agreement, each share of
TCG will be  exchanged  for .943 of an AT&T  share in an  all-stock  transaction
valued  at  the  time  at  approximately  $11.3  billion.  TCG  is  the  largest
competitive  local  exchange  carrier in the United  States,  with  networks  in
operation or under  construction in 66 U.S.  markets as of December 31, 1997. As
of September 30, 1997, TCG's local networks  encompassed over 8,680 route miles,
over 460,285  fiber miles,  and 33 local  digital  voice  switches.  These local
networks are aimed at addressing  high-volume business customers.  AT&T believes



that the TCG merger  will  accelerate  its  ability to offer  local  services to
business customers and, ultimately, to other customers.

LONG DISTANCE SERVICES

                  AT&T's   communication   and  information   services  business
addresses  the  needs of  consumers,  large and small  businesses,  the  Federal
government  and  state  and  local   governments  for  voice,   data  and  video
telecommunications  services.  Business units within this group provide  regular
and custom long distance  communications  services,  data transmission services,
500  services,  toll-free or 800 and 888 services,  900  services,  private line
services, software defined network services ("SDN"), integrated services digital
network ("ISDN") technology based services, and electronic mail, electronic data
interchanges and enhanced facsimile services.

                  AT&T also provides special long distance  services,  including
AT&T Calling Card services, special calling plans and the Company's domestic and
international   operator  services.   AT&T  provides   communications   services
internationally,   including  transaction  services,  global  networks,  network
management  and value  added  network  services  (i.e.,  services  offered  over
communications   transmission   facilities  that  employ   computer   processing
applications).

                  AT&T  provides   interstate  and   intrastate   long  distance
telecommunications   services  throughout  the  continental  United  States  and
provides, or joins in providing with other carriers, telecommunications services
to and from Alaska, Hawaii, Puerto Rico and the Virgin Islands and international
telecommunications  services to and from  virtually all nations and  territories
around the world.

                  In the continental United States,  AT&T provides long distance
telecommunications  services  over  its  own  network.  Virtually  all  switched
services are computer  controlled and digitally switched and interconnected by a
packet  switched   signaling   network.   Transmission   facilities  consist  of
approximately  2 billion  circuit-miles  using  lightwave,  satellite,  wire and
coaxial cable and microwave radio technology.  International  telecommunications
services are provided via multiple  international  transoceanic  submarine cable
(primarily  lightwave)  systems  and  via  international   satellite  and  radio
facilities.

WIRELESS SERVICES

                  AT&T is one of the world's largest wireless service providers.
In the United States,  AT&T holds licenses to operate systems  providing 850 Mhz
broadband  wireless  services  covering  markets  with a  population  of over 92
million  nationwide  and messaging and  air-to-ground  services  throughout  the
country.  The services provided by AT&T currently  include  cellular,  voice and
data,  messaging and  air-to-ground  communications.  As of December 1997,  AT&T
served over 6 million cellular subscribers.

                  In  addition,   AT&T  has  purchased  (primarily  in  auctions
conducted by the Federal  Communications  Commission  ("FCC")) 1900 Mhz wireless
broadband licenses covering markets with a population of over 112 million.  AT&T
is required  by the FCC to provide  adequate  broadband  PCS service to at least
one-third of the  population  in its  licensed  areas within five years of being
licensed and two-thirds of the population in its licensed areas within ten years
of being licensed. The licenses are granted for ten year terms from the original



date of  issuance  and may be  renewed  by AT&T by  meeting  the  FCC's  renewal
criteria and upon compliance with the FCC's renewal procedures.

                  AT&T has created service clusters in major  metropolitan areas
and linked its and other service  providers systems into a network which permits
its wireless cellular  subscribers to both place and receive calls anywhere they
travel in areas  served by the  network,  even if the local  wireless  telephone
service is not provided by AT&T.  AT&T is now integrating  other  communications
technologies into the network. AT&T will continue to explore the use of emerging
technologies  to expand  the reach of  the network  and to   provide  additional
services (especially data and internet services).

                  AT&T also  offers  one-way  messaging  systems  such as paging
services.  As of December 31, 1997,  the Company had over 1.3 million  messaging
service  subscribers.  The majority of these  subscribers are in locations where
AT&T holds cellular licenses.

                  AT&T's  wireless  services  are  conducted  primarily  through
subsidiaries  of  AT&T  Wireless   Services,   Inc.   (formerly  McCaw  Cellular
Communications, Inc., which was merged with a special-purpose subsidiary of AT&T
in September 1994).

LOCAL SERVICES

                  Following passage of the  Telecommunications  Act of 1996 (the
"Telecommunications  Act"), AT&T applied for permission to provide local service
in all 50 states.  As of December  31,  1997,  AT&T had  received  authority  to
provide  service in 48 states and the District of  Columbia.  As of December 31,
1997,  AT&T offered  AT&T  Digital  Link  service for  business  customers on an
outbound  only basis in 48 states and on an inbound  and  outbound  basis in one
state.  Also as of such date,  AT&T offered resold local service to consumers in
Alaska,  California,   Connecticut,   Georgia,  Illinois,  Michigan,  Texas  and
Rochester,  New York as well as offering  resold local service to small business
customers in California and Connecticut.

                  Notwithstanding    these   efforts,   AT&T   has   experienced
significant difficulty in penetrating local markets.  AT&T's ability to purchase
combined network elements from incumbent local exchange carriers (ILECS), one of
the  primary  methods  by  which  AT&T  intends  to  provide  local  service  to
residential and small business  customers,  was severely limited by, among other
factors, regulatory and judicial actions and a lack of technical and operational
interfaces  necessary to order network  elements from ILECs.  In spite of strong
demand,  in the fourth quarter of 1997 AT&T stopped  actively  marketing  resold
local service to residential  and small business  customers in most of the areas
in which it offered such service  because of  limitations  on ILECs'  ability to
handle  anticipated demand and because discounts AT&T receives from ILECs on the
sale of such service are  insufficient to make resale a viable  long-term method
of offering service. AT&T's ability to provide facilities-based local service to
business  customers  through AT&T Digital Link service was also  hampered by the
inability  to provide  local number  portability  and other  factors.  AT&T will
continue to pursue the development of alternative  methods of local entry, which
remains  a  key  growth  opportunity.  See  "Competition"  and  "Forward Looking
Statements" for a discussion of the potential  impact on AT&T of an inability to
profitably provide local service.



AT&T SOLUTIONS

                  AT&T   Solutions,   Inc.,   established   in  1995,   provides
outsourcing,  consulting,  networking  integration  and  multimedia  call center
services. AT&T Solutions provides clients with customized information technology
solutions to operate and manage voice, data and video services,  including local
and wide  area  networks,  PBXs,  voice-processing  systems  and  voice and data
terminals.

ONLINE SERVICES

                  AT&T also  provides a variety of online  and  internet  access
services.  These include AT&T WorldNet(R) Service, a service providing dedicated
and dial-up  access to the  internet,  AT&T Easy World Wide Web(R)  Service,  an
internet  web site  creation  and  hosting  service,  custom  web  site  hosting
services,  and AT&T SecureBuy SM Service,  an Internet  transaction service that
simplifies buying and selling on the Internet.

INTERNATIONAL

                  AT&T has  established a number of  international  alliances to
increase  the reach and scope of AT&T's  services  and network over time and has
invested in certain  countries in order to increase  the range of services  AT&T
offers in those countries.  For example, AT&T founded the WorldPartners alliance
in 1993 to provide multinational customers with seamless  telecommunications and
related services. As of the end of 1997,  WorldPartners  included 17 members who
provide  services to  multinational  customers in North America,  Latin America,
Europe,  the Middle  East and Asia.  In  addition,  in 1996 AT&T began  offering
business  and consumer  services in the United  Kingdom and in early 1997 AT&T's
joint venture in Mexico,  Alestra,  began offering long distance  service.  AT&T
also has an interest in several wireless communications companies outside of the
United  States,  including  cellular  operators  licensed  to serve  Hong  Kong,
Columbia, Taiwan and parts of India.

LEGISLATIVE AND REGULATORY DEVELOPMENTS

Telecommunications Act of 1996

                  In February 1996, the  Telecommunications  Act became law. The
Telecommunications  Act,  among  other  things,  was  designed  to foster  local
exchange  competition  by  establishing  a  regulatory  framework  to govern new
competitive entry in local and long distance  telecommunications  services.  The
Telecommunications  Act  will  permit  the  Regional  Bell  Operating  Companies
("RBOCs")  to provide  interexchange  services  originating  in any state in its
region  after  demonstrating  to the FCC that such  provision  is in the  public
interest  and  satisfying  the  conditions  for  developing  local   competition
established by the Telecommunications Act.

                  In  August  1996,  the  FCC  adopted  rules  and  regulations,
including pricing rules (the "Pricing Rules") to implement the local competition
provisions of the  Telecommunications  Act,  including with respect to the terms
and conditions of  interconnection  with local exchange carrier ("LEC") networks
and the  standards  governing  the  purchase of unbundled  network  elements and
wholesale  services  from LECs.  These  implementing  rules rely on state public
utilities commissions to develop the specific rates and procedures applicable to
particular states within the framework prescribed by the FCC.



                  On July 18, 1997,  the United  States Court of Appeals for the
8th Circuit issued a decision  holding that the FCC lacks authority to establish
pricing rules to implement the sections of the local  competition  provisions of
the  Telecommunications  Act applicable to interconnection with LEC networks and
the purchase of unbundled  network  elements and  wholesale  services from LECs.
Accordingly,  the Court  vacated  the rules  that the FCC had  adopted in August
1996, and which had been stayed by the Court since September 1996.

                  Absent  effectiveness  of the Pricing  Rules,  each state will
determine  the  applicable  rates and  procedures  independent  of the framework
established  by the FCC.  However,  since the stay was issued,  many states have
used the Pricing Rules as guidelines in establishing permanent rates, or interim
rates that will apply pending the determination of permanent rates in subsequent
state proceedings.  Nevertheless,  there can be no assurance that the prices and
other  conditions  established  in each state will provide for  effective  local
service entry and competition or provide AT&T with new market opportunities.

                  On October 14, 1997, the 8th Circuit Court of Appeals  vacated
an FCC Rule that had prohibited  incumbent LECs from separating network elements
that are combined in the LEC's network,  except at the request of the competitor
purchasing  the elements.  This decision could increase the difficulty and costs
of providing  competitive  local  service  through the use of unbundled  network
elements purchased from the incumbent LECs.

                  On January 26, 1998, the United States Supreme Court agreed to
review the  aforementioned  decisions  of the Eighth  Circuit  Court of Appeals.
Under the normal procedures of the Court,  arguments are expected to be heard in
October 1998, and a decision is expected sometime in the first half of 1999.

                  On December 31, 1997, the U.S. District Court for the Northern
District  of Texas  issued a  memorandum  opinion  and  order  holding  that the
Telecommunications  Act's restrictions on the provision of in-region,  interLATA
service   by  the  RBOCSs  are   unconstitutional.   AT&T  and  other   carriers
(collectively,  "intervenors")  and the FCC filed prompt appeals with the United
States  Court of Appeals  for the Fifth  Circuit.  On  February  11,  1998,  the
District Court stayed the  effectiveness  of its December 31 memorandum  opinion
and order pending  appeal.

                  The United States Court of  Appeals for the Fifth Circuit will
review the  aforementioned  decision of the U.S. District Court for the Northern
District of Texas under an expedited briefing  schedule,  whereby oral arguments
will be heard in July 1998. If the memorandum  opinion and order is permitted to
take effect,  the  Telecommunications  Act's  restrictions  on the  provision of
in-region interLATA services will no longer apply to the plaintiffs in the case,
SBC Communications, Inc., U S West, Inc. and Bell Atlantic Corporation.


Modification of Final Judgment of 1982

                  Prior  to  1996,  AT&T  and  the  RBOCs  were  subject  to the
provisions of the  Modification  of Final Judgment of 1982 (the "MFJ") since its
implementation.   The   Telecommunications  Act  effectively  superseded  future
operation of the MFJ.Consequently, on April 11, 1996, Judge Harold Greene issued
an order terminating the MFJ.



Regulation of Rates

                  AT&T is subject to the jurisdiction of the FCC with respect to
interstate and international rates, lines and services,  and other matters. From
July 1989 to October 1995, the FCC regulated AT&T under a system known as "price
caps" whereby AT&T's prices, rather than its earnings,  were limited. On October
12, 1995,  recognizing a decade of enormous  change in the long distance  market
and finding  that AT&T  lacked  market  power in the  interstate  long  distance
market,  the FCC reclassified AT&T as a "non-dominant"  carrier for its domestic
interstate services. As a result, AT&T became subject to the same regulations as
its long  distance  competitors  for such  services.  Thus,  AT&T was no  longer
subject to price cap  regulation  for these  services,  was able to file tariffs
that are presumed lawful on one day's notice,  and was free of other regulations
and reporting requirements that apply only to dominant carriers.

                  In addition, on October 31, 1996, the FCC issued an order that
would have prohibited non-dominant carriers, including AT&T, from filing tariffs
for their  domestic  interstate  services.  AT&T and other parties have filed an
appeal of the FCC's order with the United  States  Court of Appeals for the D.C.
Circuit.  In February 1997, the D.C.  Circuit  stayed the  effectiveness  of the
FCC's order pending  appeal.  Oral argument has not yet been  scheduled.  If the
Court  affirms  the FCC's  order and  lifts  the  stay,  non-dominant  carriers,
including AT&T, will have to utilize  mechanisms other than tariffs to establish
the terms and conditions that apply to domestic,  interstate  telecommunications
services.

                  Furthermore,  in  May  1997,  the  FCC  adopted  three  orders
relating to Price Caps, Access Reform, and Universal Service that will result in
substantial  revisions to the level and structure of access charges that AT&T as
a long distance  carrier pays to incumbent LECs. AT&T has agreed to pass through
to consumers any savings to AT&T as a result of access charge reform. AT&T began
implementing these reductions July 15, 1997. Consequently,  AT&T's results after
June 1997 reflects  lower revenue per minute of usage and lower access and other
interconnection costs per minute of usage.

                  The Price Cap Order  requires  LECs to reduce  their price cap
indices by 6.5 percent  annually,  less an adjustment  for  inflation,  which is
likely to result in a  reduction  in the  interstate  access  charges  that long
distance  carriers,  such as AT&T,  pay to LECs.  The Access Charge Reform Order
restructured  access  charges so that certain  costs that do not vary with usage
will be  recovered  on a  flat-rate  basis  and  permitted  increased  flat-rate
assessments on multiline  business customers and on residential lines beyond the
primary telephone line. This restructuring  allows a reduction in access charges
assessed on long  distance  carriers on a usage basis.  Finally,  the  Universal
Service Order (which represents an FCC mandated  contribution to support schools
and libraries and rural health care  programs,  high cost support and low income
support  mechanisms  which  are  paid to the  Universal  Service  Administrative
Company) adopts a new mechanism for funding  universal service which expands the
set of carriers  that must  contribute  to support  universal  service from only
long-distance carriers to all carriers,  including LECs, that provide interstate
telecommunications  services.  Similarly,  the set of carriers  eligible for the
universal  service  support  has been  expanded  from only LECs to any  eligible
carrier  providing local service to a customer,  including AT&T as a new entrant
in local markets.  The Universal  Service Order also adopted measures to provide
discounts on  telecommunications  services,  Internet  access and inside wire to
eligible schools and libraries and rural health carrier providers.



                  AT&T remains subject to the statutory requirements of Title II
of the  Communications  Act.  AT&T must offer  service  under  rates,  terms and
conditions that are just, reasonable and not unreasonably discriminatory;  it is
subject to the FCC's complaint  process,  and it must give notice to the FCC and
affected customers prior to discontinuance, reduction, or impairment of service.
AT&T has also made  certain  commitments  that  address  concerns  that had been
raised with regard to the potential impact of declaring AT&T to be non-dominant,
including a three-year  rate assurance for low income and low usage  residential
users and a three-year  limit on, and 5 days advance  notice for, rate increases
on 800 directory assistance and analog private line services.

                  AT&T's   international   private  line   services   have  been
classified as  non-dominant  for several years.  AT&T's  switched  international
services have become subject to increased  competition,  similar to its domestic
services and on May 9, 1996,  the FCC adopted an order  reclassifying  AT&T as a
non-dominant  carrier  for  such  services.  AT&T  has  made  certain  voluntary
commitments   that  address   issues  raised  in  that   proceeding,   including
commitments:  (i)  to  maintain  its  annual  average  revenue  per  minute  for
international  residential calls at or below the 1995 level through May 9, 1999,
and in the event of a significant change that substantially raises AT&T's costs,
to  provide  the FCC  five  business  days  notice  prior to  implementing  rate
increases that would raise the annual average  revenue per minute for such calls
above the 1995  level;  and (ii) to  maintain  certain  discount  calling  plans
providing at least a 15% discount off basic pricing schedules until May 9, 1999.
AT&T also made voluntary  commitments relating to its operation of international
cable facilities, its negotiation of settlement agreements with foreign carriers
and its relationship with foreign partners.

                  In addition to the matters described above with respect to the
Telecommunications  Act, state public service commissions or similar authorities
having  regulatory  power over  intrastate  rates,  lines and services and other
matters regulate AT&T's local and intrastate communications services. The system
of regulation used in many states is rate-of-return regulation. In recent years,
many states have adopted  different  systems of  regulation,  such as:  complete
removal of rate-of-return regulation,  pricing flexibility rules, price caps and
incentive regulation.


COMPETITION

                  AT&T   currently   faces   significant   competition   in  the
communication  and information  services  industry and expects that the level of
competition   will  continue  to  increase.   As  competitive,   regulatory  and
technological    changes   occur,    including    those    occasioned   by   the
Telecommunications Act, AT&T anticipates that new and different competitors will
enter and expand their position in the  communications  services markets.  These
may include  entrants from other segments of the  communication  and information
services  industry  or  global  competitors   seeking  to  expand  their  market
opportunities.  Many such new  competitors  are  likely  to enter  with a strong
market  presence,   well  recognized  names  and  pre-existing  direct  customer
relationships.

                  The   Telecommunications   Act  has   already   impacted   the
competitive  environment.  Anticipating changes in the industry,  non-RBOC LECs,
which are not required to implement  the  Telecommunications  Act's  competitive
checklist  prior to offering  long  distance in their home  markets,  have begun
integrating  their local  service  offerings  with long  distance  offerings  in



advance of AT&T being able to offer combined local and long distance  service in
these areas,  adversely  affecting AT&T's revenues and earnings in these service
regions.

                  In addition,  the  Telecommunications Act will permit RBOCs to
provide  interLATA  interexchange  services after  demonstrating to the FCC that
such  provision is in the public  interest and  satisfying  the  conditions  for
developing local competition  established by the  Telecommunications  Act. Three
RBOCs have petitioned the FCC for permission to provide interLATA  interexchange
services in one or more states within their home market; to date the FCC has not
granted any petition.  To the extent that the RBOCs obtain  in-region  interLATA
authority before the Telecommunications  Act's checklist of conditions have been
fully or satisfactorily implemented and adequate facilities-based local exchange
competition   exists,   there  is  a  substantial   risk  that  AT&T  and  other
interexchange  service  providers  would be at a  disadvantage  to the  RBOCs in
providing both local service and combined service packages. Because it is widely
anticipated  that  substantial  numbers of long distance  customers will seek to
purchase local,  interexchange  and other services from a single carrier as part
of a combined or full service package, any competitive  disadvantage,  inability
to  profitably   provide  local  service  at  competitive  rates  or  delays  or
limitations  in  providing  local  service or combined  service  packages  could
adversely  affect  AT&T's  future  revenues  and  earnings.  In any  event,  the
simultaneous entrance of numerous new competitors for interexchange and combined
service  packages is likely to  adversely  affect  AT&T's  future long  distance
revenues and could adversely affect future earnings.

                  Furthermore, in February 1997, a General Agreement on Trade in
Services (the "GATS") was reached under the World Trade Organization.  The GATS,
which  became  effective  January 1, 1998,  is designed  to open each  country's
domestic telecommunications markets to foreign competitors. The GATS, and future
trade  agreements,  may accelerate the entrance into the U.S.  market of foreign
telecommunications  providers,  certain of whom are  likely to possess  dominant
home market positions in which there is not effective competition.  The GATS may
also  permit  AT&T's  entrance  into  other  markets  as only a small  number of
countries refused to eliminate their foreign ownership restrictions.

                  In addition to the matters  referred to above,  various  other
factors, including market acceptance, start-up and ongoing costs associated with
the  provision  of new  services  and  local  conditions  and  obstacles,  could
adversely  affect  the  timing and  success  of AT&T's  entrance  into the local
exchange  services market and AT&T's ability to offer combined  service packages
that include local service.

FORWARD LOOKING STATEMENTS

                  Except for the historical statements and discussions contained
herein,  statements  contained in this Report on Form 10-K  constitute  "forward
looking  statements"  within the meaning of Section 27A of the Securities Act of
1933 and  Section 21E of the  Securities  Exchange  Act of 1934.  Any Form 10-K,
Annual Report to Shareholders, Form 10-Q or Form 8-K of AT&T may include forward
looking  statements.  In  addition,  other  written  or  oral  statements  which
constitute  forward  looking  statements have been made and may in the future be
made by or on behalf of AT&T, including  statements  concerning future operating
performance,  AT&T's  share  of new and  existing  markets,  AT&T's  short-  and
long-term  revenue and earnings growth rates,  and general industry growth rates
and AT&T's performance  relative thereto.  These forward looking statements rely
on a number of assumptions  concerning  future events,  including the outcome of



litigation,  the adoption and implementation of balanced and effective rules and
regulations  by the FCC and the state  public  regulatory  agencies,  and AT&T's
ability  to achieve a  significant  market  penetration  in new  markets.  These
forward looking  statements are subject to a number of  uncertainties  and other
factors,  many of which are outside  AT&T's  control,  that could  cause  actual
results to differ  materially from such statements.  These factors include,  but
are not limited to:

- - the efficacy of the rules and  regulations  to be adopted by the FCC and state
public regulatory agencies to implement the provisions of the Telecommunications
Act; the outcome of litigation  relative  thereto;  and the impact of regulatory
changes relating to access reform and international settlement reform;

- - the outcome of negotiations  with LECs and state  regulatory  arbitrations and
approvals  with  respect  to  interconnection  agreements;  and the  ability  to
purchase  unbundled network elements or wholesale  services from LECs at a price
sufficient  to permit  the  profitable  offering  of local  exchange  service at
competitive rates;

- - success and market acceptance for new initiatives, many of which are untested;
the level  and  timing  of the  growth  and  profitability  of new  initiatives,
particularly  local  (consumer and business)  service and business data service;
start-up costs associated with entering new markets,  including  advertising and
promotional  efforts;  successful  deployment of new systems and applications to
support new initiatives; and local conditions and obstacles;

- -   competitive   pressures,   including   pricing   pressures,    technological
developments,  alternative  routing  developments,  and  the  ability  to  offer
combined  service  packages that include local  service;  the extent and pace at
which  different  competitive  environments  develop  for  each  segment  of the
telecommunications  industry;  the extent at and duration for which  competitors
from each segment of the telecommunications  industry are able to offer combined
or full  service  packages  prior to AT&T being able to; and the degree to which
AT&T  experiences  material  competitive  impacts  to  its  traditional  service
offerings prior to achieving adequate local service entry;

- - the  availability,  terms and deployment of capital;  the impact of regulatory
and  competitive  developments on capital  outlays;  the ability to achieve cost
savings  and  realize  productivity  improvements;  the  ability to  effectively
integrate  TCG's  operations  with AT&T; the ability to realize  cost-saving and
revenue synergies from the merger; and

- - general economic conditions,  government and regulatory policies, and business
conditions in the communications industry.

                  Readers  are  cautioned  not to put  undue  reliance  on  such
forward  looking  statements.  For a more  detailed  description  of  these  and
additional  uncertainties  and other factors that could cause actual  results to
differ  materially  from  such  forward  looking  statements,  see  "Results  of
Operations",  "Financial Condition",  "Regulatory and Legislative Developments",
and "Competition"  included in or incorporated by reference into this Form 10-K.
As described  elsewhere in this Form 10-K, these uncertainties and factors could
adversely  affect  the  timing and  success  of AT&T's  entrance  into the local
exchange  services market and AT&T's ability to offer combined  service packages
that include local service,  thereby adversely  affecting AT&T's future revenues
and earnings. AT&T disclaims any intention or obligation to update or revise any
forward  looking  statements,  whether  as a result of new  information,  future
events or otherwise.


SEGMENT, OPERATING REVENUE AND RESEARCH AND DEVELOPMENT EXPENSE INFORMATION

                  For information  about the Company's  research and development
expense, see Note 5 to the Consolidated  Financial  Statements.  For information
about the  consolidated  operating  revenues  contributed by the Company's major
classes of products and services,  see the revenue  tables and  descriptions  on
pages 28  through  30 and  Consolidated  Statements  of Income on page 40 of the
Company's  annual report to  shareholders  for the year ended December 31, 1997.
All such  information is  incorporated  herein by reference  pursuant to General
Instruction G(2).

EMPLOYEE RELATIONS

                  At  December  31,  1997 AT&T  employed  approximately  128,000
persons  in  its   operations,   approximately   122,000  of  whom  are  located
domestically.  About  48% of the  domestically  located  employees  of AT&T  are
represented by unions. Of those so represented, about 96% are represented by the
Communications Workers of America ("CWA"), which is affiliated with the AFL-CIO;
about 4% by the International  Brotherhood of Electrical Workers ("IBEW"), which
is also  affiliated  with  the  AFL-CIO.  In  addition,  there  is a very  small
remainder of domestic  employees  represented by other unions.  Labor agreements
with most of these unions extend through May 1998.

ITEM 2.  PROPERTIES.

                  The  properties  of  AT&T  consist   primarily  of  plant  and
equipment used to provide long distance and wireless telecommunications services
and administrative office buildings.

                  Telecommunications  plant and equipment  consists of:  central
office equipment,  including  switching and transmission  equipment;  connecting
lines  (cables,  wires,  poles,  conduits,   etc.);  land  and  buildings;   and
miscellaneous properties (work equipment,  furniture,  plant under construction,
etc.).  The  majority  of the  connecting  lines are on or under  public  roads,
highways and streets and international and territorial waters. The remainder are
on or under  private  property.  AT&T also  operates a number of sales  offices,
customer care centers,  and other  facilities,  such as research and development
laboratories.

                  AT&T continues to manage the deployment and utilization of its
assets  in order to meet its  global  growth  objectives  while at the same time
ensuring  that  these  assets  are  generating  economic  value  added  for  the
shareholder.  AT&T will  continue  to  manage  its asset  base  consistent  with
globalization   initiatives,   marketplace   forces,   productivity  growth  and
technology change.

                  A substantial number of the administrative offices of AT&T are
in  leased   buildings.   Substantially  all  of  the  important  long  distance
communications  facilities are in buildings wholly owned by AT&T or in buildings
owned partially by AT&T and partially by the regional holding  companies created
at divestiture.  Many of the smaller facilities are in rented quarters.  Most of
the important  buildings used in connection  with long distance  services are on
land held in fee, but a few are on land held under long-term leases.



ITEM 3.  LEGAL PROCEEDINGS.

                  In  the  normal  course  of  business,   AT&T  is  subject  to
proceedings,  lawsuits and other claims,  including proceedings under government
laws and regulations  related to environmental  and other matters.  Such matters
are  subject  to  many  uncertainties  and  outcomes  are not  predictable  with
assurance.  Consequently,  AT&T is unable to ascertain  the  ultimate  aggregate
amount of monetary  liability or financial  impact with respect to these matters
at December 31, 1997. While these matters could affect operating  results of any
one quarter when resolved in future  periods,  it is  management's  opinion that
after final  disposition,  any monetary  liability  or financial  impact to AT&T
beyond  that  provided  for at year-end  would not be material to AT&T's  annual
consolidated financial position or results of operations.

                  On July 6, 1997,  MCI  Telecommunications  Corp. and Ronald A.
Katz  Technology  Licensing,  L.P. filed suit in United States District Court in
Philadelphia,  Pennsylvania against AT&T. The suit alleges that a number of AT&T
services  infringe  patents  owned by Katz but  licensed to MCI for  enforcement
against  AT&T.  AT&T is reviewing the  allegations  of the  Complaint.  Based on
review to date,  it is  management's  opinion that the claims do not present any
material  monetary  liability or financial impact to AT&T that is not subject to
patent indemnity agreements with third-party equipment vendors.

                  AT&T  is also a  named  party  in a  number  of  environmental
actions,  none of which is material to the consolidated  financial statements or
business  of  the  Company.   In  addition,   pursuant  to  the  Separation  and
Distribution  Agreement by and among AT&T, Lucent, and NCR, dated as of February
1, 1996,  and amended  and  restated  as of March 29,  1996,  Lucent has assumed
liability,  subject to the liability sharing provisions of that agreement, for a
number of  actions in which AT&T  remains a named  party.  AT&T is working to be
released as a party to these actions, although there can be no assurance that it
will be successful in this regard.

                  There are four environmental proceedings which are required to
be reported  pursuant to  Instruction  5.C.  of Item 103 of  Regulation  S-K. In
September  1997,  the  government of the U.S.  Virgin  Islands filed suit in the
federal district court of the Virgin Islands against the Company, AT&T Submarine
Systems International ("SSI International"), A&L Underground, Inc., a contractor
for SSI  International at that time, and other entities.  In connection with the
purported  1996 release of non-toxic  bentonite  drilling mud within the coastal
region of St. Croix by the  contractor,  the suit seeks penalties for violations
of various federal and Virgin Island statutes;  damages under several  statutory
and common law theories;  removal of the mud (which has since been  completed to
the  satisfaction  of  the  federal  agency  that  ordered  the  cleanup);   and
restitution  of response costs  allegedly  incurred by the Virgin  Islands.  SSI
International  was a wholly owned  subsidiary of AT&T at the time of the alleged
violation.  The  foregoing  environmental  proceeding  is  not  material  to the
consolidated  financial  statements  or business of the Company and would not be
reported but for  Instruction 5 C. of Item 103 of Regulation S-K, which requires
disclosure of such matters.

                  In  addition,  three  proceedings  involve  matters  for which
Lucent has assumed  liability,  as described above. On July 31, 1991, the United
States Environmental Protection Agency Region III issued a complaint pursuant to
Section 3008a of the Resource  Conservation and Recovery Act alleging violations
of  various  waste  management  regulations  at the  Company's  Richmond  Works,
Richmond, Virginia. The complaint seeks a total of $4.2 million in penalties. In



addition,  on July 31, 1991, the United States  Environmental  Protection Agency
filed a civil complaint in the U.S.  District Court for the Southern District of
Illinois  against the Company and nine other parties seeking  enforcement of its
Comprehensive Environmental Response,  Compensation and Liability Act ("CERCLA")
Section  106 cleanup  order,  issued in  November  1990 for the NL Granite  City
Superfund site,  Granite,  Illinois,  past costs, civil penalties of $25,000 per
day and treble damages related to certain United States' costs. Finally,  during
1994, AT&T Nassau Metals  Corporation  ("Nassau"),  a wholly owned subsidiary of
AT&T, and the New York State Department of Environmental Conservation ("NYSDEC")
were  engaged in  negotiations  over a study and  cleanup  of the  Nassau  plant
located  on  Richmond  Valley  Road in Staten  Island,  New York.  During  these
negotiations,  in June 1994,  NYSDEC presented Nassau with a draft consent order
which  included  not  only  provisions   relating  to  site   investigation  and
remediation  but also a  provision  for  payment of a $3.5  million  penalty for
alleged  violations  of  hazardous  waste  management  regulations.   No  formal
proceeding has been commenced by NYSDEC.



ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY-HOLDERS.

                  No  matter was submitted  to a vote of security holders in the
fourth quarter of the fiscal year covered by this report.

Corp. and subsidiaries has been incorporated by reference in this Form 10-K from
