ITEM 1. BUSINESS
 
  GENERAL
 
    MediaOne Group, Inc. ("MediaOne Group" or the "Company") is incorporated
under the laws of the State of Delaware and has its principal executive offices
at 188 Inverness Drive West, Englewood, Colorado 80112, telephone number (303)
858-3000. MediaOne Group (NYSE: UMG) is one of the world's largest broadband
communications companies, bringing the power of broadband and the Internet to
more than seven million customers in the United States, Europe and Asia. The
Company also has interests in some of the world's fastest-growing wireless
communications businesses, serving more than four million customers outside the
United States. For 1998, the businesses now part of MediaOne Group produced $7.1
billion in proportionate revenue. (Financial information concerning MediaOne
Group's operations is set forth in the Consolidated Financial Statements and
Notes thereto, which begin on page 46.) At December 31, 1998, MediaOne Group and
its subsidiaries employed a total of 16,847 people.
 
    Prior to June 12, 1998, MediaOne Group was known as "U S WEST, Inc." On June
12, 1998, U S WEST, Inc. (the "Old U S WEST") separated its businesses into two
independent public companies (the "Separation"). Until the Separation, Old U S
WEST conducted its businesses through two groups: U S WEST Media Group and U S
WEST Communications Group. Upon the Separation, Old U S WEST was renamed
"MediaOne Group, Inc." and retained the multimedia businesses of U S WEST Media
Group, except for U S WEST Dex, Inc., the domestic directory business, which
became aligned with U S WEST Communications Group. The telecommunications
businesses of U S WEST Communications Group, along with the domestic directory
business of U S WEST Dex, Inc., became an independent public company and
retained the "U S WEST, Inc." name.
 
    MediaOne Group bases its strategy on the belief that advanced networks will
continue to grow in importance to how we live, work and play. Over time, this
global phenomenon will result in networks being increasingly critical and
delivering ever-increasing value to consumers and, consequently, to our
shareholders.
 
    RECENT DEVELOPMENT
 
    On March 22, 1999, MediaOne Group announced that it had entered into a
merger agreement with Comcast Corporation ("Comcast") whereby MediaOne Group
would be merged into Comcast. The merger agreement calls for MediaOne Group
common shareholders to receive 1.1 shares of Comcast Class A Special Common
Stock for each share of MediaOne Group common stock held. The transaction will
be tax-free to MediaOne Group shareholders. Subject to the approval of both
shareholder groups and various federal, state and local regulatory bodies, the
merger could be completed as early as year-end 1999. While the merger agreement
prohibits MediaOne Group from soliciting competing acquisition proposals,
MediaOne Group may, subject to compliance with the terms of the merger agreement
and payment of a $1.5 billion fee to Comcast, accept a superior proposal that is
submitted within 45 days of the date of the merger agreement.
 
    OPERATIONS
 
    MediaOne Group is the third largest cable television system operator in the
United States. MediaOne Group has operations and investments in two principal
areas: (i) domestic broadband communications, and (ii) international broadband
and wireless communications. Among its investments, MediaOne Group holds a
25.51% interest in Time Warner Entertainment Company, L.P. ("TWE"), a provider
of cable programming, filmed entertainment and broadband communications services
that is the second largest cable television system operator in the United
States.
 
    DOMESTIC BROADBAND COMMUNICATIONS--MEDIAONE NETWORKS.  As of December 31,
1998, MediaOne Group's domestic cable television systems passed approximately
8.5 million homes and provided service to
 
                                       1
<PAGE>
approximately 5.0 million basic cable subscribers. MediaOne Group's systems
include large clusters in Atlanta, Massachusetts, California, Florida, Detroit
and Minneapolis/St. Paul. As of December 31, 1998, approximately 97% of MediaOne
Group's total basic subscribers were located in clusters with a population
greater than 100,000 (after giving effect to announced swaps). MediaOne Group
believes that its operating scale in key markets generates significant benefits,
including operating efficiencies, and enhances its ability to develop and deploy
new broadband technologies and services.
 
    MediaOne Group's domestic cable services are marketed under the "MediaOne"
brand and are operated by its wholly owned subsidiary, MediaOne of Delaware,
Inc. ("MediaOne"). MediaOne Group's cable systems offer customers various levels
(or "tiers") of cable programming services consisting of broadcast television
signals available off-the-air in any locality, televisions signals from
so-called "super stations" originating in distant cities (such as WGN), various
satellite-delivered non-broadcast channels (such as CNN, MTV, USA Network, ESPN,
the Discovery Channel and Nickelodeon), displays of information featuring news,
weather, stock and financial market reports and programming originated locally
by the systems (such as public, governmental and educational access channels).
MediaOne Group's systems also provide premium programming service to their
customers for an extra monthly charge. These premium programming services
include HBO, Cinemax, Showtime, The Movie Channel, Encore and regional sports
networks. Customers generally pay initial connection charges and fixed monthly
fees for a tier of programming services and additional fixed monthly fees for
premium programming services. MediaOne Group also offers pay-per-view
programming of movies and special events for an additional per-program charge.
 
    MediaOne Group's systems have channel capacity and addressability that are
among the highest in the cable industry. MediaOne Group's systems are located
primarily in suburban communities adjacent to major metropolitan markets and in
mid-sized cities that generally are densely populated and geographically
diverse. MediaOne Group believes that the geographic diversity of its system
clusters reduces its exposure to economic, competitive or regulatory factors of
any particular region.
 
    MediaOne Group is upgrading its cable systems to create broadband hybrid
fiber-coax ("HFC") networks. These HFC networks will provide increased channel
capacity for the delivery of additional cable programming and facilitate the
delivery of additional services, such as telephony services, enhanced video
services, Internet access services and high-speed data services. MediaOne Group
is selectively upgrading its systems and expects that it will have approximately
70% of its systems upgraded to 750 MHz by the end of 1999. MediaOne Group has
already begun to offer additional services over upgraded HFC networks in certain
markets. On June 15, 1998, MediaOne Group entered into a joint venture with Time
Warner, Inc. ("TWX"), TWE and Time Warner Entertainment-Advance/Newhouse
Partnership ("TWE/AN") to provide high speed data ("HSD") services. The parties
to the joint venture contributed certain of their respective HSD assets to the
joint venture in exchange for common equity interests. In addition, Microsoft
Corporation and Compaq Computer Corporation each contributed approximately $212
million for respective 10% preferred equity interests in the joint venture,
which are convertible into common equity interests. Assuming the conversion of
the preferred shares and taking into account MediaOne Group's ownership in TWE,
MediaOne Group would hold a proportionate diluted common equity interest in the
joint venture of 34.6%. MediaOne Group will provide the HSD services under the
"Road Runner" brand name.
 
    DOMESTIC BROADBAND COMMUNICATIONS--TIME WARNER CABLE.  MediaOne Group owns a
25.51% priority capital and residual equity interest in TWE. The remaining
interests in TWE are owned by TWX. TWE is engaged in the cable programming,
filmed entertainment and broadband communications businesses. TWE, through Time
Warner Cable, its cable division, is the second-largest cable television system
operator in the United States. Time Warner Cable owns or manages cable systems
in 34 states. These systems include 33 clusters of more than 100,000
subscribers, including Time Warner Cable of New York City, the largest cluster
in the United States. More than 62% of Time Warner Cable's subscribers are
located in Florida, New York, North Carolina, Ohio and Texas. As of December 31,
1998, Time Warner Cable owned
 
                                       2
<PAGE>
cable television systems that passed approximately 17.5 million homes and
provided service to approximately 10.8 million basic cable subscribers. Of these
systems, systems passing approximately 10.1 million homes and providing service
to approximately 6.3 million subscribers are owned by Time Warner
Entertainment-Advance/Newhouse Partnership ("TWE-A/N"), a partnership in which
TWE owns a 64.8% interest, the Advance/Newhouse Partnership ("A/N") owns a 33.3%
interest and TWX owns a 1.9% interest. In addition, Time Warner Cable manages
cable television systems owned by TWX which, as of December 31, 1998, passed
approximately 3.1 million homes and provided service to approximately 1.8
million cable television subscribers. Time Warner Cable's cable services are
marketed under the "Time Warner Cable" brand. Time Warner Cable offers cable
programming services over its networks similar to those offered by MediaOne
Group under the MediaOne brand. Like MediaOne Group, Time Warner Cable is
upgrading its cable systems to provide increased channel capacity and to
facilitate the delivery of additional services.
 
    INTERNATIONAL BROADBAND COMMUNICATIONS.  MediaOne Group owns interests in
various providers of broadband communications services in international markets
in continental Europe, the United Kingdom and Asia. As of December 31, 1998,
these interests represented approximately 2.6 million proportionate homes passed
and 993,000 proportionate subscribers.
 
    Among its international broadband interests, MediaOne Group holds a 29.9%
interest in Telewest Communications plc ("Telewest"), the largest provider of
combined cable and telecommunications services in the United Kingdom. Telewest
is constructing broadband networks capable of providing a broad range of video,
telephony and data services. As of December 31, 1998, Telewest had approximately
999,000 cable subscribers and 1,565,000 telephone lines. MediaOne Group also
holds interests in other providers of cable and broadband communications
services in international markets, including a 97.1% interest in Cable Plus
a.s., a provider of cable and telephony services in the Czech Republic; a 50%
interest in A2000 (KTA), a provider of cable and telephony services in the
Netherlands; a 25% interest in Telenet, a provider of cable and telephony
services over an HFC network in portions of Belgium; a 25% interest in Singapore
Cablevision Pte Ltd, a joint venture that is constructing a broadband network in
Singapore; and a 25% interest in Titus Communications Corp. ("Titus") and a 19%
interest in Chofu Cable Television ("Chofu"), each of which is constructing
cable television systems in Japan. TWX also holds a 25% interest in Titus and a
19% interest in Chofu.
 
    INTERNATIONAL WIRELESS COMMUNICATIONS.  MediaOne Group owns interests in
various providers of wireless communications services in international markets
in continental Europe, the United Kingdom and Asia. As of December 31, 1998,
these interests represented 72.8 million proportionate potential customers and
approximately 1,734,000 proportionate customers.
 
    Among its international wireless interests, MediaOne owns a 50% interest in
Mercury Personal Communications ("One 2 One"), which provides personal
communications services ("PCS") in the United Kingdom under the brand "One 2
One." The remaining 50% of One 2 One is owned by Cable & Wireless plc. One 2 One
was the first PCS service in the world to commence operations in 1993. As of
December 31, 1998, One 2 One's networks served approximately 1,921,000 customers
and provided coverage to approximately 96% of Great Britain's population.
MediaOne Group also holds interests in various other providers of wireless
communications services in international markets, including a 49% interest in
Westel 900 and a 49% interest in Westel Radiotelefon, providers of cellular
service in Hungary; 24.5% interests in Eurotel Praha and Eurotel Bratislava,
providers of wireless services in portions of the Czech and Slovak Republics; a
22.5% interest in Polska Telefonia Cyfrowa, a provider of Global Systems for
Mobile Communications ("GSM") cellular services in Poland; a 49% interest in BPL
Cellular Telecommunications, a provider of GSM cellular services in certain
regions of India; and a 66.5% interest in the Russian Telecommunications
Development Corp., a provider of cellular services in certain cities in Russia.
 
    REGULATION.  The products and services of MediaOne Group are subject to
varying degrees of regulation. Under the Telecommunications Act of 1996 (the
"Telecommunications Act"), it is anticipated
 
                                       3
<PAGE>
that the regulation of all but basic tier cable and equipment rates will be
discontinued effective March 31, 1999. However, as described below, the Company
must seek the permission of the Federal Communications Commission ("FCC") to end
rate regulation for cable systems covered by MediaOne's social contract. The
Telecommunications Act also eliminated certain cross-ownership restrictions
among cable operations, broadcasters and multipoint multichannel distribution
services ("MMDS") operations and removed barriers to competition with local
exchange carriers ("LECs").
 
    The Cable Television Consumer Protection and Competition Act of 1992 (the
"1992 Cable Act") provided for the regulation of rates for certain cable
television services and for equipment and installation charges. The FCC was
charged with setting the standards for rate regulation, but also approved
"social contracts" as an alternative form of regulation. MediaOne's Social
Contract was the first approved by the FCC. The Social Contract is a six-year
agreement covering most of MediaOne's franchises and settled all of MediaOne's
outstanding rate complaints. As part of the Social Contract, MediaOne agreed to,
among other things, invest at least $1.7 billion in domestic system rebuilds and
upgrades through the year 2000 to expand channel capacity and improve system
reliability and picture quality. As of December 31, 1998, the investment
commitment had been met; however, the Company must still upgrade all systems
covered by the Social Contract to a minimum of 550MHz, with at least half being
upgraded to 750 MHz. The Social Contract also provides that, if the laws and
regulations applicable to services offered in any MediaOne franchise change in a
manner that would have a material favorable financial impact on MediaOne, the
Company may petition the FCC to terminate the Social Contract. The sunset of
rate regulation for the upper tiers of cable service represents such a change
and the FCC may not unreasonably refuse to terminate the rate regulation
provision of the Social Contract.
 
    Cable television systems are also subject to local regulation, typically
imposed through the franchising process. Local officials may be involved in the
initial franchise selection, franchise service area, construction standards,
safety, rate regulation of the lowest tier of service and equipment and
installation rates, customer service standards, billing practices,
community-related programming and services, franchise renewal and imposition of
franchise fees.
 
    MediaOne Group is also subject to various regulations in the foreign
countries in which it has operations. In the United Kingdom, the licensing,
construction, operation, sale and acquisition of cable and wireline and wireless
communications systems are regulated by various government entities, including
the Department of Trade and Industry and the Department of National Heritage.
 
    In June, 1998, the FCC issued formal rules providing for the retail sale of
set-top television boxes which integrate security and non-security functions. On
January 1, 2005, cable companies will no longer be permitted to sell or lease
new integrated boxes to their subscribers. In addition, cable companies must
provide subscribers with related security modules that plug into set-top boxes
that are purchased from consumer electronics retailers by July 1, 2000. In
February 1999, MediaOne Group partnered with various manufacturers of digital
set-top boxes in order to provide an open conditional access system, which would
be compliant with domestic OpenCable-TM- specifications.
 
    COMPETITION.  MediaOne Group's cable television systems generally compete
for viewer attention and advertising dollars with other providers of video
programming, including direct broadcast satellite ("DBS") systems, MMDS systems,
local multipoint distribution services systems, satellite master antenna
television ("SMATV") systems and other cable companies providing services in
areas where MediaOne Group operates. In addition, certain LECs, including RBOCs,
are beginning to offer video programming in competition with MediaOne Group's
cable services. In the past, federal cross-ownership restrictions have limited
entry by LECs into the cable television business. The Telecommunications Act has
eliminated many of these barriers, thereby enhancing the ability of LECs to
provide video programming in competition with MediaOne Group. The extent of such
competition in any franchise area is dependent, in part, upon the quality,
variety and price of the programming provided by these services. Many of these
competitive services are generally not subject to the same local government
regulation that affects cable television. The cable television services offered
by MediaOne Group also face competition for viewers and advertising
 
                                       4
<PAGE>
from other communications and entertainment media, including off-air television
broadcasting services, movie theaters, video tape rentals and live sporting
events. The competition faced by MediaOne Group's cable systems may increase in
the future with the development and growth of new technologies.
 
    As MediaOne Group continues to offer additional services over its HFC
networks, MediaOne Group will face additional competition. The high-speed data
and telephony services offered by MediaOne Group face competition from other
providers, including regional bell operating companies, LECs, inter-exchange
carriers ("IXCs"), Internet service providers and other providers of local
exchange and on-line services. The degree of competition will be dependent upon
the state and federal regulations concerning entry, interconnection requirements
and the degree of unbundling of the LECs' networks. Competition will be based
upon product, service quality, breadth of services offered and, to a lesser
extent, on price.
 
    MediaOne Group's international broadband and wireless communications
businesses also face competition in their respective markets. Telewest's cable
television services compete with broadcast television stations, DBS services,
SMATV systems and certain narrowband operators in the United Kingdom. Telewest's
communications services compete with domestic telephone companies in the United
Kingdom, such as British Telecommunications plc. One 2 One competes with three
cellular operators in the United Kingdom. Competition is based upon price,
geographic coverage and quality of the services offered.
 
ITEM 2. PROPERTIES.
 
    MediaOne Group's principal physical assets consist of cable television
operating plant and equipment, including signal receiving, encoding and decoding
devices, headends and distribution systems and customer house drop equipment for
each of its cable television systems. The signal receiving apparatus typically
includes a tower, antenna, ancillary electronic equipment and earth stations for
reception of satellite signals. Headends, consisting of related electronic
equipment necessary for the reception, amplification and modulation of signals,
are located near the receiving devices. The physical components of cable
television systems require maintenance and periodic upgrading to keep pace with
technological changes.
 
    MediaOne Group owns or leases parcels of real property for signal reception
sites (antenna towers and headends), microwave facilities and business offices
in each of its market areas and owns most of its service vehicles. MediaOne
Group believes that its properties, both owned and leased and taken as a whole,
are in good operating condition and are suitable and adequate for MediaOne
group's business operations.
 
ITEM 3. LEGAL PROCEEDINGS.
 
    MediaOne Group, Inc. and its subsidiaries are subject to claims and
proceedings arising in the ordinary course of business. While complete assurance
cannot be given as to the outcome of any contingent liabilities, in the opinion
of MediaOne Group, any financial impact to which MediaOne Group and its
subsidiaries are subject is not expected to be material in amount to MediaOne
Group's operating results or its financial position.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

------------------------
 
(1) On June 12, 1998, U S WEST, Inc. ("Old U S WEST") separated its businesses
    into two independent public companies (the "Separation"). Prior to the
    Separation, Old U S WEST conducted its businesses through two groups: U S
    WEST Media Group ("Media Group") and U S WEST Communications Group
    ("Communications Group"). Upon Separation, Old U S WEST was renamed MediaOne
    Group, Inc. ("MediaOne Group" or the "Company") and retained the businesses
    of Media Group, except for U S WEST Dex, Inc. ("Dex"), the domestic
    directory business. The telecommunications businesses of Communications
    Group became an independent public company and retained the "U S WEST, Inc."
    name ("New U S WEST"). In addition, Dex was aligned with New U S WEST.
    MediaOne Group has accounted for the distribution to shareowners of New U S
    WEST as a discontinuance of the businesses comprising New U S WEST. 1998
    income from discontinued operations includes a gain on Separation of $24,461
    ($40.25 per share of MediaOne Group Stock). See Note 24--Discontinued
    Operations--to the Consolidated Financial Statements.
 
(2) 1998, 1997 and 1996 sales and other revenues include $2,191, $2,070 and
    $252, respectively, related to Continental Cablevision, Inc. ("Continental")
    which was acquired by MediaOne Group on November 15, 1996 (the "Continental
    Acquisition"). In addition, 1998, 1997, 1996, 1995 and 1994 sales and other
    revenues include $361, $1,428, $1,183, $941 and $781, respectively, related
    to the domestic wireless operations which were sold on April 6, 1998.
 
(3) 1998 income from continuing operations includes a net gain of $2,257 ($3.71
    per share of MediaOne Group Stock) on the sale of the domestic wireless
    businesses, net gains of $44 ($0.08 per share of MediaOne Group Stock) on
    the sales of various domestic investments, net income of $20 ($0.04 per
    share of MediaOne Group Stock) related to the domestic wireless businesses,
    net loss from operations of $384 ($0.63 per share of MediaOne Group Stock)
    related to Continental, and a net loss of $100 ($0.16 per share of MediaOne
    Group Stock) related to the PrimeStar investment. 1997 income from
    continuing operations includes net gains of $249 ($0.41 per share of
    MediaOne Group Stock) on the sales of various domestic and international
    investments, net income of $83 ($0.13 per share of MediaOne Group Stock)
    related to the domestic wireless businesses and net loss from operations of
    $356 ($0.59 per share of MediaOne Group Stock) related to Continental. 1996
    income from continuing operations includes net income of $96 ($0.19 per
    share of MediaOne Group Stock) related to the domestic wireless businesses,
    net loss from operations of $71 ($0.15 per share of MediaOne Group Stock)
    related to Continental and a charge of $19 ($0.04 per share of MediaOne
    Group Stock) related to the sale of MediaOne Group's cable television
    interests in Norway, Sweden and Hungary. 1995 income from continuing
    operations includes a gain of $95 ($0.20 per share of MediaOne Group Stock)
    from the merger of Telewest Communications plc ("Telewest") with SBC
    CableComms (UK), net income of $58 ($0.12 per share of MediaOne Group Stock)
    related to the domestic wireless businesses and costs of $9 ($0.02 per share
    of MediaOne Group Stock) associated with the Recapitalization Plan discussed
    in footnote 9 below. 1994 income from continuing operations includes a gain
    of $105 ($0.23 per share) on the partial sale of MediaOne Group's joint
    venture interest in Telewest, a gain of $41 ($0.09 per share) on the sale of
    MediaOne Group's paging operations and net income of $33 ($0.07 per share)
    related to the domestic wireless businesses.
 
(4) 1998 net income was reduced by an extraordinary item of $333 ($0.55 per
    share of MediaOne Group Stock) for the early extinguishment of debt in
    conjunction with the Separation. 1995 net income was reduced by an
    extraordinary item of $4 ($0.01 per share of MediaOne Group Stock) for the
    early extinguishment of debt.
 
(5) Debt at December 31, 1998, 1997 and 1996 includes debt related to the
    Continental Acquisition. Debt and the percentage of debt to total capital
    for years prior to 1998 exclude the capital assets segment which had been
    discontinued and held for sale, and the discontinued operations of New U S
    WEST which were distributed to shareowners effective June 12, 1998.
    Percentage of debt to total capital includes Company-obligated mandatorily
    redeemable preferred securities of subsidiary trust holding
 
                                       12
<PAGE>
    solely Company-guaranteed debentures ("Preferred Securities"), preferred
    stock subject to mandatory redemption and the minority interest in Centaur
    Funding Corporation ("Centaur"), as a component of total capital. Including
    Preferred Securities, preferred stock subject to mandatory redemption, the
    minority interest in Centaur and debt related to the capital assets segment
    as components of debt, MediaOne Group's percentage of debt to total capital
    would have been 37.5%, 48.1%, 47.4%, 30.7% and 29.7% at December 31, 1998,
    1997, 1996, 1995 and 1994, respectively. Capital expenditures exclude the
    capital assets segment and the discontinued operations of New U S WEST.
 
(6) Includes Preferred Securities of $1,061 at December 31, 1998, and $1,080 at
    December 31, 1997 and 1996, and $600 at December 31, 1995; preferred stock
    subject to mandatory redemption of $100 at December 31, 1998 and 1997, and
    $51 at December 31, 1996, 1995 and 1994; and minority interest in Centaur of
    $1,099 at December 31, 1998.
 
(7) MediaOne Group considers earnings before interest, taxes, depreciation,
    amortization and other ("EBITDA") an important indicator of the operational
    strength and performance of its businesses. EBITDA, however, should not be
    considered an alternative to operating or net income as an indicator of the
    performance of MediaOne Group's businesses, or as an alternative to cash
    flows from operating activities as a measure of liquidity, in each case
    determined in accordance with generally accepted accounting principles
    ("GAAP").
 
(8) Proportionate results represent the relative weight of the Company's
    ownership in each of its respective domestic and international equity
    ventures, combined with its consolidated results. Proportionate information
    is not intended to replace financial and operating data prepared in
    accordance with GAAP since proportionate results depart materially from
    GAAP. However, MediaOne Group believes that proportionate financial and
    operating data facilitate the understanding and assessment of its results.
    Proportionate EBITDA excludes domestic wireless EBITDA of $114, $398, $307,
    $226 and $161 for 1998, 1997, 1996, 1995 and 1994, respectively.
 
(9) Effective with the Separation on June 12, 1998, each outstanding common
    share of Media Group stock remains outstanding and represents one share of
    MediaOne Group common stock ("MediaOne Group Stock"). In addition, all
    shares of Communications Group stock were canceled. See Note 17-- Earnings
    Per Share--to the Consolidated Financial Statements--for a discussion of
    Communications Group stock earnings per share. The average common shares of
    MediaOne Group Stock outstanding for the year ended December 31, 1996
    include 150,615,000 shares issued in connection with the Continental
    Acquisition. Effective November 1, 1995, each share of common stock of Old U
    S WEST was converted into one share each of Communications Group stock and
    Media Group stock (the "Recapitalization Plan"). Earnings per common share
    and dividends per common share for 1995 have been presented on a pro forma
    basis to reflect the two classes of stock as if they had been outstanding
    since January 1, 1995.

    Some of the information presented in or in connection with this report
constitutes "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995. Although the Company believes that its
expectations are based on reasonable assumptions within the bounds of its
knowledge of its business and operations, there can be no assurance that actual
results will not differ materially from its expectations. Factors that could
cause actual results to differ from expectations include: (i) greater than
anticipated competition from new entrants into the cable and wireless
communications markets, (ii) changes in demand for the Company's products and
services, (iii) regulatory changes affecting the cable and telecommunications
industries, (iv) a change in economic conditions in the various markets served
by MediaOne Group's operations, including international markets, that could
adversely affect the level of demand for cable, wireless or other services
offered by the Company, (v) greater than anticipated competitive activity
requiring new pricing for services, (vi) higher than anticipated start-up costs
associated with new business opportunities, (vii) higher than anticipated
employee levels, capital expenditures, and operating expenses (such as costs
associated with Year 2000 remediation), (viii) consumer acceptance of broadband
services, including telephony and data services, and wireless services, (ix)
increases in fraudulent activity with respect to broadband and wireless
services, or (x) delays in the development of anticipated technologies, or the
failure of such technologies to perform according to expectations.
 
    On March 22, 1999, MediaOne Group announced that it had entered into a
merger agreement with Comcast Corporation ("Comcast") whereby MediaOne Group
would be merged into Comcast. The merger agreement calls for MediaOne Group
common shareowners to receive 1.1 shares of Comcast Class A Special Common Stock
for each share of MediaOne Group common stock held. The transaction will be
tax-free to MediaOne Group shareowners. Subject to the approval of both
shareowner groups, and various federal, state and local regulatory bodies, the
merger could be completed as early as year-end 1999. While the merger agreement
prohibits MediaOne Group from soliciting competing acquisition proposals,
MediaOne Group may, subject to compliance with the terms of the merger agreement
and payment of a $1.5 billion fee to Comcast, accept a superior proposal that is
submitted within 45 days of the date of the merger agreement.
 
THE SEPARATION
 
    Prior to June 12, 1998, MediaOne Group, Inc. ("MediaOne Group" or the
"Company") was known as "U S WEST, Inc." ("Old U S WEST"). On June 12, 1998, Old
U S WEST separated its businesses into two independent public companies (the
"Separation"). Until the Separation, Old U S WEST conducted its businesses
through two groups: U S WEST Media Group (the "Media Group") and U S WEST
Communications Group (the "Communications Group"). The performance of Media
Group was reflected by the U S WEST Media Group Common Stock (the "Media Stock")
and the performance of the Communications Group was reflected by the U S WEST
Communications Group Common Stock (the "Communications Stock"). Upon Separation,
Old U S WEST was renamed "MediaOne Group, Inc." and retained the multimedia
businesses of Media Group, except for U S WEST Dex, Inc. ("Dex"), the domestic
directory business. The telecommunications businesses of the Communications
Group became an independent public company and retained the "U S WEST, Inc."
name ("New U S WEST"). In addition, Dex was aligned with New U S WEST (the "Dex
Alignment"). Each outstanding share of Media Stock remains outstanding and
represents one share of MediaOne Group Common Stock ("MediaOne Group Stock").
All issued and outstanding shares of Communications Stock were redeemed for
shares of New U S WEST, and all Communications Stock held as treasury stock by
Old U S WEST was canceled.
 
    The Company accounted for the distribution of New U S WEST stock to the
Communications Group stockholders, and to the Media Group stockholders for the
Dex Alignment, as a discontinuance of the
 
                                       14
<PAGE>
businesses comprising New U S WEST. Because the distribution was non pro-rata,
as compared with the businesses previously attributed to Old U S WEST's two
classes of stock, the distribution was accounted for at fair value and resulted
in a gain of $24,461, or $40.25 basic earnings per MediaOne Group share, net of
$114 of Separation costs (net of tax benefits of $37).
 
    In connection with the Dex Alignment, (i) each holder of Media Stock
received as a dividend .02731 shares of New U S WEST common stock for each share
of Media Stock held (the "Dex Dividend"), and (ii) $3.9 billion of Old U S WEST
debt was refinanced by New U S WEST.
 
    In conjunction with the Separation, MediaOne Group refinanced substantially
all of the indebtedness issued or guaranteed by Old U S WEST through a
combination of tender offers, prepayments and consent solicitations (the
"Refinancing"). Long-term debt outstanding of $4.9 billion was redeemed,
resulting in an extraordinary loss of $333, net of tax benefits of $209, or
$0.55 basic loss per MediaOne Group share. The loss was the result of
refinancing costs, including the difference between the market and face value of
the debt redeemed and a charge for unamortized debt issuance costs. MediaOne
Group financed the redemption with short-term commercial paper at a weighted
average interest rate of 5.85 percent. In addition, in accordance with the terms
of a separation agreement between MediaOne Group and New U S WEST (the
"Separation Agreement"), New U S WEST funded to MediaOne Group $3.9 billion
related to the Dex Alignment. Such funds were used to repay a portion of the
commercial paper issued in connection with the Refinancing.
 
BUSINESS DESCRIPTION
 
    MediaOne Group has operations and investments in two principal areas: (i)
domestic broadband communications, and (ii) international broadband and wireless
communications. On April 6, 1998, MediaOne Group sold its domestic wireless
businesses to AirTouch Communications, Inc. ("AirTouch") in a tax-efficient
transaction (the "AirTouch Transaction"). This included MediaOne Group's 2.6
million domestic cellular communication customers, as well as its 25 percent
interest in PrimeCo Personal Communications, L.P. ("PrimeCo"). See Note
4--Domestic Acquisitions and Dispositions--to the Consolidated Financial
Statements.
 
    DOMESTIC BROADBAND COMMUNICATIONS.  The Company is the third largest cable
operator in the United States serving approximately 5.0 million cable customers
and passing 8.5 million homes. MediaOne Group's cable systems include large
clusters in Atlanta, Massachusetts, California, Florida, Detroit and
Minneapolis/St. Paul. The cable systems offer customers various levels of cable
programming services, including premium programming services such as HBO,
Cinemax, Showtime, The Movie Channel and Encore, as well as pay-per-view movies
and special events. The domestic cable and broadband operations of the Company
are managed by MediaOne of Delaware, Inc. ("MediaOne"), a subsidiary of MediaOne
Group.
 
    In addition to its cable operations, the Company also holds significant
domestic cable and broadband investments including an investment in Time Warner
Entertainment Company L.P. ("TWE" or "Time Warner Entertainment"), the second
largest provider of cable television services in the United States, and
interests in programming that include E! Entertainment Television and New
England Cable News. MediaOne Group also holds an equity investment in a joint
venture called "ServiceCo, LLC" (the "HSD Joint Venture"). Such venture was
formed on June 15, 1998, with Time Warner, Inc., ("Time Warner"), TWE and Time
Warner Entertainment-Advance/Newhouse Partnership ("TWE/AN") to provide high
speed data ("HSD") services. The parties to the joint venture contributed
certain of their respective HSD assets into the HSD Joint Venture in exchange
for common equity interests. In addition, Microsoft Corporation and Compaq
Computer Corporation each contributed $212.5 for a respective 10 percent
preferred equity investment in the HSD Joint Venture, convertible into a
combined 20 percent common equity interest in the HSD Joint Venture. Assuming
the conversion of the preferred shares and taking into account MediaOne Group's
ownership in TWE, MediaOne Group would hold a proportionate diluted common
equity interest in the HSD Joint Venture of approximately 34.6 percent. MediaOne
Group will
 
                                       15
<PAGE>
provide HSD services under the "Road Runner" brand name. See Note 4--Domestic
Acquisitions and Dispositions--to the Consolidated Financial Statements.
 
    INTERNATIONAL BROADBAND COMMUNICATIONS.  Internationally, the Company holds
an investment in Telewest Communications plc ("Telewest"), a provider of cable
television, telecommunications and Internet services to business and residential
customers in the United Kingdom. As a result of a rights offering to its
existing shareholders, including MediaOne Group, and the Company's partial
acquisition of a third party's ownership in Telewest, MediaOne Group now holds a
29.9 percent interest in Telewest. See Note 7--Net Investment in International
Ventures--to the Consolidated Financial Statements. The Company also holds
interests in cable and broadband properties in the Netherlands, Belgium, the
Czech Republic, Japan and Singapore.
 
    INTERNATIONAL WIRELESS COMMUNICATIONS.  MediaOne Group holds a 50 percent
joint venture interest in Mercury Personal Communications ("One 2 One"), a
provider of personal communications services ("PCS") in the United Kingdom, in
addition to interests in various wireless properties in Hungary, the Czech and
Slovak Republics, Poland, Russia and India.
 
    The following discussion is based on MediaOne Group's Consolidated Financial
Statements prepared in accordance with generally accepted accounting principles
("GAAP").

    The decrease in normalized loss from continuing operations was primarily a
result of decreased equity losses generated by unconsolidated international
ventures and decreased interest expense due to lower debt levels at MediaOne
Group. The table above normalizes for significant one-time items that aid in the
comparability of the Company's performance year over year. Routine acquisitions
and dispositions are normalized within the discussions of revenues and operating
income which follow.

</TABLE>
 
    Domestic cable and broadband revenues increased during 1998 due primarily to
increased video revenues, partially offset by the lack of PrimeStar direct
broadcast services ("DBS") revenues in the last three quarters of 1998.
Normalized for the one-time effects of cable system acquisitions and
dispositions, a change in classification of late fee revenues, and the
discontinuance of PrimeStar DBS revenues, total domestic cable and broadband
revenues increased 10.6 percent during 1998.
 
    BASIC CABLE.  Basic cable services revenues increased during 1998 due
primarily to a 9.5 percent increase in revenue per average cable subscriber and
increased basic subscribers. At December 31, 1998, basic cable subscribers were
4,965,000, an increase of 1.0 percent compared with the same period in 1997,
normalized for the effects of cable system acquisitions and dispositions. The
increase in revenue per subscriber is the result of expanded channel offerings,
repackaging of services and increased rates.
 
                                       17
<PAGE>
    PREMIUM.  Premium service revenues decreased during 1998 due primarily to
discounting of premium service packages, movements of certain premium service
packages to basic, and a migration of customers to lower priced premium service
packages. In an effort to improve premium service revenues, the Company
repackaged its premium services and launched "NexTV" in September 1998, a
packaging program which clusters related premium channels. At December 31, 1998,
premium units were 4,176,000, an increase of 3.6 percent compared with the same
period in 1997, normalized for the effects of cable system acquisitions and
dispositions.
 
    PAY-PER-VIEW.  Pay-per-view revenues decreased during 1998 due to a lack of
major sporting events in 1998 as compared with 1997. The decline was slightly
offset by increased revenues on movies.
 
    ADVERTISING.  Advertising revenues increased during 1998 as a result of
expanded channel capacity, growth in local and national advertising sales, and
increased rates.
 
    EQUIPMENT AND INSTALLATION.  Equipment and installation revenues increased
in 1998 due primarily to subscribers upgrading converter boxes.
 
    OTHER.  Other revenues include franchise fee payments, revenues received for
guides and miscellaneous revenues. The decrease in other revenues during 1998 is
due primarily to the classification of late fee revenues in 1998; late fee
revenues were reflected in "other revenues" during 1997, whereas in 1998 these
revenues are classified as an offset to "selling, general and administrative
expenses."
 
    VIDEO.  Video revenue per average cable subscriber was $40.33 per month for
the year-ended December 31, 1998, an increase of 6.8 percent, compared with
$37.76 for the same period in 1997. Adjusted for the one-time effects of cable
system acquisitions and dispositions and a change in classification of late fee
revenues, video revenue per average cable subscriber increased 7.8 percent
during 1998. Video revenue per average cable subscriber has increased as a
result of expanded channel offerings, repackaging of services and increased
rates.
 
    Video revenues increased 9.4 percent during 1998, normalized for the
one-time effects of cable system acquisitions and dispositions, and for the
change in classification of late fee revenues.
 
    NEW PRODUCTS.  New products revenues increased during 1998 due primarily to
the launch and customer growth of HSD Internet access services in new markets,
and growth in business dedicated telephony services.
 
    At December 31, 1998, MediaOne Group had approximately 84,000 HSD customers
compared with 21,000 HSD customers for the same period in 1997, and was
available to over 3 million market-ready HSD homes. Market-ready homes are those
potential customers which are connected to the broadband network and which could
be provided and billed for service. HSD Internet access services are available
in 11 metro areas in the following states: California, Florida, Georgia,
Illinois, Massachusetts, Michigan, Minnesota, New Hampshire and Ohio.
 
    On June 15, 1998, MediaOne Group formed the HSD Joint Venture with Time
Warner, TWE and TWE/AN to deliver HSD services. The HSD Joint Venture is
responsible for maintaining connections to the Internet, providing technical
customer support and developing national content. The parties to the joint
venture operate their respective HSD businesses and are responsible for their
respective customers' billing and customer service issues. Accordingly, MediaOne
Group continues to reflect HSD services revenues in its consolidated results, as
well as a service fee payable to the HSD Joint Venture for services provided.
MediaOne Group will provide HSD services under the "Road Runner" brand name.

    During 1998 MediaOne Group began offering residential telephony services to
six metro areas within the states of California, Florida, Georgia,
Massachusetts, and Virginia. As of December 31, 1998, residential telephony
services were available to approximately 530,000 market-ready homes.
 
    During November 1998, MediaOne Group entered into a definitive agreement
with Hyperion Communications to sell the Company's investments in Continental
Fiber Technologies, Inc. and Alternet of Virginia, Inc., providers of business
telephony services in Jacksonville, Florida and Richmond, Virginia,
respectively, for approximately $80, (the "CLEC Businesses"). The sale is
expected to close in the first half of 1999. The CLEC Businesses contributed
business telephony revenues of $14 and operating losses of $3 during 1998. These
results have been included as part of New Products revenues and domestic cable
and broadband revenues and operating income.
 
    PRIMESTAR.  Prior to April 1, 1998, MediaOne Group distributed PrimeStar DBS
services to subscribers in its service areas, and as a result, reflected
consolidated operating results with respect to such subscribers. On April 1,
1998, MediaOne Group contributed its interest in PrimeStar Partners, L.P. ("Old
PrimeStar"), as well as its PrimeStar subscribers and certain related assets to
PrimeStar, Inc. ("PrimeStar") (the "PrimeStar Contribution"). Consequently,
subsequent to April 1, 1998, MediaOne Group no longer reflects consolidated
operating results for PrimeStar DBS services. In fourth-quarter 1998, MediaOne
Group wrote-off its investment in PrimeStar received as part of the PrimeStar
Contribution. See Note 4-- Domestic Acquisitions and Dispositions-- and Note
22--Subsequent Events--to the Consolidated Financial Statements.
 
    CABLE AND BROADBAND--INTERNATIONAL.  International cable and broadband
revenues represent the consolidated operations of Cable Plus a.s., a cable
operator in the Czech Republic.
 
    OTHER.  Other revenues in 1997 primarily included the Company's wholly-owned
international directory operations in the United Kingdom and Poland. Such
operations were sold in June and October 1997, respectively.
 
    DOMESTIC WIRELESS.  On April 6, 1998, MediaOne Group sold its domestic
wireless businesses to AirTouch pursuant to the AirTouch Transaction. See Note
4--Domestic Acquisitions and Dispositions--to the Consolidated Financial
Statements.

<PAGE>
    During 1998, MediaOne Group's operating income decreased $269 to a loss of
$239, primarily a result of selling the domestic wireless businesses in April,
1998. Excluding the effects of the domestic wireless businesses, operating
income has decreased primarily as a result of greater depreciation and
amortization expenses from the domestic cable and broadband operations,
partially offset by decreased operating losses from the wholly-owned
international directories operations which were sold in 1997.
 
    MediaOne Group's earnings before income taxes, depreciation, amortization
and other ("EBITDA") for 1998 were $943, compared with $1,287 during the same
period in 1997. Excluding the effect of the domestic wireless operations, EBITDA
would have been $795 in 1998, compared with $754 in the same period of 1997.
MediaOne Group considers EBITDA an important indicator of the operational
strength and performance of its businesses. EBITDA, however, should not be
considered an alternative to operating or net income as an indicator of the
performance of MediaOne Group's businesses, or as an alternative to cash flows
from operating activities as a measure of liquidity, in each case determined in
accordance with GAAP.
 
    CABLE AND BROADBAND--DOMESTIC.  Domestic cable and broadband operating
losses increased during 1998 due primarily to increased depreciation and
amortization expense. As MediaOne Group continues to upgrade its cable networks,
depreciation expense will continue to increase. During the first quarter of
1998, there was a one-time increase to depreciation and amortization expense of
$28 related to the termination of the sale of cable systems in Minnesota.
Depreciation and amortization expense had been suspended on these systems in
1997 while they were held for sale. This increase was offset by a reduction to
depreciation and amortization expense of $29 for systems held for sale during
1998.
 
    During 1998, EBITDA for domestic cable and broadband operations was $941, an
increase of $11, or 1.2 percent, compared with $930 in 1997. Revenue increases
of $144, or 6.2 percent, exceeded increased programming costs of $50, or 9.5
percent, and increased operating, general and administrative costs of $83, or
9.6 percent. Of those amounts, the PrimeStar Contribution provided revenue
decreases of $75 and cost decreases of $63, including $25 of programming costs,
to total domestic cable and broadband EBITDA for the period. Normalized for the
one-time effects of cable system acquisitions and dispositions, domestic cable
and broadband EBITDA increased 2.2 percent.
 
    Video EBITDA was $995 for 1998, an increase of $47, or 5.0 percent, compared
with $948 during 1997. Normalizing for acquisitions and dispositions, and
excluding Year 2000 implementation costs of $13 during 1998, video EBITDA was
$1,008 for 1998, an increase of $57, or 6.0 percent, compared with 1997.
 
    New Products EBITDA was $(58), an increase in losses of $(24), or 70.6
percent, compared with EBITDA of $(34) in 1997. New Products revenue increases
of $30 were offset by New Products costs increases of $54 during the period.
 
    Programming costs were $575 for 1998, an increase of $50, or 9.5 percent,
over 1997. Excluding programming costs related to PrimeStar DBS services,
programming costs increased 15.7 percent. The normalized increase was primarily
a result of greater programming costs per subscriber as a result of rate
increases, expanded channel offerings and growth in subscribers.
 
    Operating, general and administrative costs were $951 during 1998, an
increase of $83, or 9.6 percent, over 1997. Increases in operating, general and
administrative costs were primarily a function of increases in employee costs
due to improvements in customer service, marketing and advertising costs
associated with the deployment of new products, such as HSD services and
residential telephony, as well as NexTV, and spending on initiatives to improve
the operations of the Company. These cost increases were partially offset by
decreased costs related to the PrimeStar Contribution. During 1998, MediaOne
Group incurred costs of $15 to improve reporting and billing systems, and to
create customer databases to serve customers more effectively, and costs of $13
for incremental Year 2000 implementation costs, for a total of $28.

    CABLE AND BROADBAND--INTERNATIONAL.  The decrease in international cable and
broadband operating losses is the result of increased revenues and decreased
operating expenses, due primarily to efficiency gains and reduced headcount.
 
    INTERNATIONAL WIRELESS.  International wireless operating losses represent
the consolidated operations of Russian Telecommunications Development
Corporation ("RTDC"), a Russian venture, which holds various wireless
investments.
 
    CORPORATE.  The decrease in corporate operating losses during 1998 is due
primarily to a $30 charge in 1997 for management changes and moving costs
related to relocating MediaOne's operations from Boston to Denver. The decrease
was partially offset by increased overhead costs during 1998.
 
    OTHER.  Operating losses decreased $11 during 1998 due to the sales in 1997
of the wholly-owned international directories operations. In addition, costs
incurred for the development of domestic Internet content services have
decreased during 1998 primarily as a result of aligning certain of these
operations within the domestic cable and broadband operations.

</TABLE>
 
    INTEREST EXPENSE.  Interest expense decreased during 1998 due primarily to
the June 12, 1998 assumption by New U S WEST of $3.9 billion of debt related to
the Dex Alignment, the Refinancing which resulted in lower interest rate
commercial paper outstanding, and the assumption of $1,350 in debt by AirTouch
in the AirTouch Transaction. The reduction in interest expense was partially
offset by the third-quarter 1998 issuance of $1,686 of debt exchangeable into
AirTouch common stock and a charge of $16 related to the termination of various
interest rate swap agreements. The swap agreements were terminated since the
long term debt underlying the instruments was refinanced at the time of the
Separation. MediaOne Group's weighted average borrowing cost was 7.28 percent in
1998, compared with 6.95 percent in 1997.
 
    EQUITY LOSSES IN UNCONSOLIDATED VENTURES.  Equity losses decreased during
1998 due predominantly to a $200 charge in 1997 to write down the carrying value
of the investment in Malaysia to its fair value of zero and to recognize
probable funding commitments in connection with a shareholder support agreement
related to the investment in Indonesia. In addition, during 1998, the Company
suspended equity method accounting for the Company's investments in Malaysia and
Indonesia, compared with equity losses recognized in 1997 of $71 and $46,
respectively. The Company continues to monitor its investments in Indonesia and
Malaysia. See Note 7--Net Investment in International Ventures--to the
Consolidated Financial Statements.
 
    Also contributing to the decrease in equity losses during 1998 were overall
improvements from the international wireless investments and the absence of
losses from the investment in PrimeCo, which was sold to AirTouch on April 6,
1998 pursuant to the AirTouch Transaction.
 
                                       21

    GAIN ON SALE OF DOMESTIC WIRELESS INVESTMENT.  On April 6, 1998, MediaOne
Group sold its domestic wireless businesses to AirTouch. Consideration under the
AirTouch Transaction consisted of (i) debt reduction of $1,350, (ii) the
issuance to MediaOne Group of $1,650 in liquidation preference of dividend
bearing AirTouch preferred stock (fair value of $1,493), and (iii) the issuance
to MediaOne Group of 59,314,000 shares of AirTouch common stock. The transaction
resulted in a pretax gain of $3,869, ($2,257 net of deferred taxes). MediaOne
Group is accounting for its investment in AirTouch under the cost method of
accounting, as available for sale securities. See Note 4--Domestic Acquisitions
and Dispositions--to the Consolidated Financial Statements.
 
    GAINS ON SALES OF INVESTMENTS.  During 1998, MediaOne Group sold: (a) shares
of Sportsline USA, Inc. and shares of Cable & Wireless Optus Limited resulting
in pretax gains of $12 ($8 after tax) and $9 ($6 after tax), respectively, (b) a
cable programming investment resulting in a pretax gain of $17 ($10 after tax),
(c) various domestic cable investments resulting in a pretax gain of $16 ($10
after tax) and (d) miscellaneous items resulting in a pretax gain of $16 ($10
after tax).
 
    LOSS ON PRIMESTAR INVESTMENT.  During the fourth quarter of 1998, MediaOne
Group recorded a charge of $163 ($100 after tax) to reduce the carrying amount
of its investment in PrimeStar. In December 1998, PrimeStar management provided
a business plan to its board of directors, of which MediaOne Group is a part.
Additionally, in early 1999, PrimeStar announced that it was selling its DBS
medium-power business and assets to Hughes Electronics Corporation ("Hughes").
Based on the review of PrimeStar's business plan and on the anticipated sale to
Hughes, MediaOne Group believes that it will not receive proceeds on the sale of
its investment in PrimeStar, and therefore, reduced the carrying amount of its
investment to zero. See Note 22--Subsequent Events--to the Consolidated
Financial Statements.
 
    GUARANTEED MINORITY INTEREST EXPENSE.  Guaranteed minority interest expense
has decreased $21 during 1998 due primarily to the cash redemption on June 12,
1998, of $301 face value of 7.96 percent Company-obligated mandatorily
redeemable preferred securities of subsidiary trust holding solely
Company-guaranteed debentures ("Preferred Securities") and $237 face value of
8.25 percent Preferred Securities. The decrease was partially offset by the
issuance in October 1998 of $500 face value of 9.04 percent Preferred
Securities.
 
    OTHER INCOME (EXPENSE)--NET.  Other income during 1998 was favorably
impacted by decreased foreign exchange transaction losses of $51, dividend
income earned on the AirTouch preferred stock received in connection with the
AirTouch Transaction of $66, and the lack of minority interest expense of $37
from the domestic wireless operations due to the sale of these operations in
connection with the AirTouch Transaction. Such improvements were partially
offset by a $50 loss related to an interest rate swap agreement associated with
the AirTouch preferred stock and a related $20 loss for the purchase of a new
interest rate option. See Note 4--Domestic Acquisitions and Dispositions--to the
Consolidated Financial Statements.

    During 1997, the Continental Acquisition contributed approximately $356, or
$0.59 per share, of the increase in normalized loss from continuing operations.
The Continental Acquisition resulted in significant increases in interest,
depreciation and amortization charges. The remaining increase in loss from
continuing operations is primarily due to greater losses from unconsolidated
ventures.

<PAGE>
    CABLE AND BROADBAND--DOMESTIC.  On a pro forma basis, domestic cable and
broadband revenues increased due primarily to growth in basic cable services
revenues and PrimeStar DBS services revenues.
 
    BASIC CABLE.  Basic cable services revenues increased $146, or 10.6 percent,
to $1,518 on a pro forma basis, primarily a result of rate increases. Rate
increases averaged approximately 6 to 8 percent and were primarily related to an
increase in programming costs and the addition of channels. Basic subscriber
growth of 1.6 percent, adjusted for dispositions and an acquisition, also
contributed to the increase in revenues.
 
    PREMIUM.  Premium service revenues decreased $20, or 5.8 percent, to $326 on
a pro forma basis, as a result of moving the Disney Channel to the basic service
tier in several markets and discounting of premium service packages.
 
    EQUIPMENT AND INSTALLATION.  Equipment and installation revenues increased
$19, or 14.3 percent, to $152 on a pro forma basis, as a result of rate
increases and subscriber growth.
 
    VIDEO.  Video revenue per average cable subscriber increased 4.7 percent to
$37.76 in 1997, from $36.06 in 1996. Basic subscriber growth of 1.6 percent,
adjusted for dispositions and an acquisition, also contributed to the increase
in revenues along with growth in equipment rental and installation revenues.
 
    PRIMESTAR.  PrimeStar DBS services contributed $40 to the increase in
domestic cable and broadband revenues principally as a result of a 31 percent
increase in DBS customers to 181,000 at December 31, 1997.
 
    CABLE AND BROADBAND--INTERNATIONAL.  International cable and broadband
revenues reflect the consolidation of Cable Plus associated with a restructuring
in 1996 whereby the Company's ownership interest increased to 94 percent.
 
    OTHER.  The decrease in other revenues is due primarily to the sale of the
Company's wholly- owned international directories operations during the latter
part of 1997.
 
    DOMESTIC WIRELESS.  Domestic wireless revenues increased during 1997 due
primarily to increased cellular service revenues of $198, or 18.4 percent, to
$1,276, and increased cellular equipment revenues of $47, or 44.8 percent, to
$152. Cellular service revenues increased due to a 27 percent increase in
subscribers during the year, partially offset by a 12 percent drop in average
revenue per subscriber to $46.42 per month. Cellular equipment revenues
increased as a result of a 14 percent increase in gross customer additions and
the introduction of digital handsets.
 
    On April 6, 1998, the Company sold its domestic wireless businesses to
AirTouch pursuant to the AirTouch Transaction.

------------------------
 
(1) Gives effect to the Continental Acquisition as though it had occurred on
    January 1, 1996.
 
(2) Primarily includes wholly-owned international directories which were sold in
    the latter part of 1997.
 
    MediaOne Group pro forma operating income increases were due primarily to
growth in domestic wireless, partially offset by higher domestic cable and
broadband operating losses.
 
    CABLE AND BROADBAND--DOMESTIC.  Pro forma domestic cable and broadband
revenue growth of $198, or 9.3 percent, to $2,323, was more than offset by
increases in programming costs, including programming for PrimeStar DBS
services, of $71, or 15.6 percent, to $525, increases in operating, marketing
and advertising, and general and administrative costs of $89, or 11.4 percent,
to $868, and increases in depreciation and amortization expense of $76, or 7.9
percent, to $1,041.
 
    Programming cost increases are primarily a result of rate increases and
subscriber growth. Increases in operating, marketing and advertising, and
general and administrative costs are primarily a function of customer service
initiatives, costs associated with deployment of new services such as high-speed
data, advertising costs to implement the "MediaOne" brand and increased
professional fees. A reduction in the estimated remaining useful lives of
certain assets in accordance with planned re-build activities resulted in a
depreciation adjustment of $61 which accounts for the majority of the increase
in depreciation and amortization expense during 1997.
 
    CORPORATE.  Corporate operating losses include costs related to managing the
various MediaOne Group operations, predominantly the international operations,
and costs related to general and administrative services provided by the Company
to its subsidiaries, including executive management, legal, accounting and
auditing, tax, treasury, strategic planning, and public policy.
 
    The 1997 results include a $30 charge for management changes and moving
costs related to relocating MediaOne's operations from Boston to Denver. This
charge was partially offset by savings associated with lower international staff
levels in 1997, combined with a 1996 charge of $10 related to the staff
reductions at international headquarters.
 
    OTHER.  Other operating losses include the Company's wholly-owned
international directories operations which were sold during 1997
 
    DOMESTIC WIRELESS.  The increase in domestic wireless operating income is a
result of revenue increases associated with the expanding subscriber base
combined with efficiency gains. Domestic cellular depreciation and amortization
increased 22.4 percent, to $180, largely as a result of network upgrades.

</TABLE>
 
    INTEREST EXPENSE.  Interest expense increased in 1997 primarily as a result
of assuming, at market value, $6.5 billion of debt related to the Continental
Acquisition. MediaOne Group's weighted average borrowing cost was 6.95 percent
in 1997, compared with 6.80 percent in 1996.
 
    EQUITY LOSSES IN UNCONSOLIDATED VENTURES.  Equity losses increased $563 in
1997, predominantly a result of greater losses generated from international
ventures and the domestic investment in PrimeCo. PrimeCo launched service in
November 1996, and losses associated with this venture have increased $68 as a
result of start-up and other costs.
 
    International equity losses increased $455 in 1997, due primarily to
ventures located in Asia, which included Indonesia, India, Malaysia, Japan and
Singapore. The ventures in Asia contributed $397 to the increase in
international equity losses due primarily to a $200 impairment charge recorded
in the period. During 1997 the Company determined that its investments in
Malaysia and Indonesia were impaired and in each case the fair value of the
investment was zero as of December 31, 1997. The Company recorded pretax charges
of $145 and $55 related to the ventures in Malaysia and Indonesia, respectively.
See Note 7--Net Investment in International Ventures--to the Consolidated
Financial Statements.
 
    GAINS ON SALES OF INVESTMENTS.  During 1997, the Company sold: (i) its 90
percent interest in Fintelco, for a pretax gain of $135 ($80 after tax), (ii)
its shares of Teleport Communications Group, Inc. ("TCG"), acquired in the
Continental Acquisition, for a pretax gain of $162 ($96 after tax), (iii) its
shares of Time Warner, acquired in the Continental Acquisition, for a pretax
gain of $44 ($25 after tax), (iv) its five percent interest in a French wireless
venture, for a pretax gain of $51 ($31 after tax), and (v) U S WEST Polska, its
wholly owned directory operation in Poland, for a pretax gain of $29 ($17 after
tax).
 
    GUARANTEED MINORITY INTEREST EXPENSE.  Guaranteed minority interest expense
reflects an increase of $32 related to the October 29, 1996 issuance of
Preferred Securities totaling $480.
 
    OTHER INCOME--NET.  Other income increased $32, to other income of $16, in
1997, due primarily to a 1996 pretax charge of $31 associated with the sale of
the Company's cable television interests in Norway, Sweden and Hungary.
Partially offsetting this increase were greater foreign exchange transaction
losses associated with loans to international ventures.

Cash provided by operating activities..................................................  $     564  $     995  $     431
</TABLE>
 
    The decrease in the Company's cash provided by operating activities during
1998 is due primarily to the sale of the domestic wireless operations on April
6, 1998, as well as from interest payments and Separation costs paid. Partially
offsetting the decrease in cash provided by operating activities were increased
tax receipts of $85 from the Communications Group, the receipt in 1998 of $51 in
international dividends, primarily from Westel 450 and Westel 900, the Company's
European wireless investments in Hungary, and the receipt of $40 in dividends
from the AirTouch preferred stock.
 
    During 1997, the Company's operating cash flow increased primarily due to
the effects of the Continental Acquisition. Partially offsetting the increase
were higher financing costs resulting from greater debt levels associated with
the Continental Acquisition.
 
    Effective June 12, 1998, New U S WEST is no longer part of the consolidated
tax return of MediaOne Group. As of December 31, 1998, MediaOne Group had a $375
income tax receivable recorded for the estimated amount due from the carryback
of the 1998 taxable loss to the 1996 consolidated tax return. MediaOne Group
received $359 in the first quarter of 1999. MediaOne Group will receive a cash
benefit from any 1999 taxable loss in the year 2000 by the carryback of the loss
to the 1997 consolidated tax return. A cash benefit for any ordinary tax loss
incurred in the year 2000 may be recovered through the carryforward of the loss
against future taxable income.
 
    MediaOne Group expects that cash from operations will not be adequate to
fund expected cash requirements in 1999. Additional funding will come from cash
on hand, 1999 asset sales and new debt financing, including the monetization of
AirTouch common stock.

    Total capital expenditures at MediaOne Group, on a cash basis, were $1,726,
$1,522 and $627 during 1998, 1997 and 1996, respectively. The majority of the
capital expenditures in 1998 were devoted to upgrading the domestic cable
network and preparing for the provision of new and enhanced services. In 1999,
capital expenditures are expected to approximate $1.8 billion, primarily for the
domestic cable and broadband business.

    Investing activities of the Company include equity investments in
international ventures. The Company invested $583, $334 and $257 in
international ventures during 1998, 1997 and 1996, respectively. Investments
during 1998 were net of a $45 return of capital from a wireless investment in
the United Kingdom. During 1998, MediaOne Group invested $131 as a result of the
Company's participation in a rights offering by Telewest in connection with that
company's acquisition of General Cable, and $394 by purchasing an additional 175
million Telewest shares from another Telewest shareholder, for a total
investment in Telewest of $525. The remaining international investments made
during 1998 were capital contributions to its cable investments in Belgium, the
Netherlands, Japan and Singapore. The Company also made capital contributions to
ventures in the Slovak Republic, India and Indonesia. During 1997 MediaOne Group
made capital contributions to ventures in Belgium, India, Indonesia and Japan,
and purchased an additional 40 percent interest in Fintelco. The total
investment in Fintelco was subsequently sold in October 1997. Investments in
1996 included loans provided to One 2 One, the purchase of a 23 percent interest
in Polska Telefonia Cyfrowa, a venture to provide wireless service in Poland,
and the purchase of a 28 percent interest in Telenet, a venture in Belgium to
provide telephony services on the cable network. The Company anticipates that
investments in international ventures will approximate $160 in 1999 to fund
continued expansion in Belgium, the Netherlands, India, Japan and Singapore.
 
    The Company also invested $108, $249 and $164 in 1998, 1997 and 1996,
respectively, in domestic ventures. Of such investments, $64, $213 and $132
related to contributions to PrimeCo during 1998, 1997 and 1996, respectively,
for network build activity. On April 6, 1998, the Company sold its investment in
PrimeCo in conjunction with the AirTouch Transaction. The remaining $44 of
investments in domestic ventures for 1998 related to investments in various
Internet content service providers.
 
    MediaOne Group also purchased various domestic cable systems and investments
in 1998 totaling $92. Such purchases included a cable system in Michigan for $57
which serves approximately 31,000 cable subscribers.
 
    During the first quarter of 1997, the Company paid the cash portion of the
Continental Acquisition consideration of $1,150 to the Continental shareowners.
 
    During 1998, MediaOne Group sold various investments resulting in net
proceeds of $241, comprised of the following: (a) net proceeds of $77 related to
the PrimeStar Contribution, (b) various cable systems for net proceeds of $50,
(c) residual shares in Enhance Financial Services Group, Inc., and shares of
SportsLine USA, Inc. and Cable & Wireless Optus Limited for total net proceeds
of $46, (d) a cable programming investment for net proceeds of $38, and (e)
miscellaneous investments for net proceeds of $30. In addition, MediaOne Group
paid a net amount of $164 related to other activities as follows: (a) paid $215
related to the settlement of an interest rate swap agreement and the purchase of
a related put option, (b) received proceeds of $71 on the sale of a note
receivable, (c) restricted $26 of cash related to Centaur Funding Corporation
("Centaur"), a special purpose entity consolidated by the Company, and (d)
received $6 for miscellaneous asset sales.
 
    Throughout 1997, the Company monetized nonstrategic assets, including
various domestic and international investments. Such asset sales generated total
proceeds of $2,058. Proceeds from sales of international investments totaled
$887, domestic investments totaled $931, assets held for sale totaled $231, and
disposals of property, plant and equipment totaled $9. International sales
consisted of: (a) a five percent interest in a French wireless venture for
proceeds of $81, (b) a 90 percent interest in Fintelco for proceeds of $641, (c)
Thomson Directories, the directory operation in the United Kingdom, and U S WEST
Polska, the directory operation in Poland, for net proceeds of $121 and $27,
respectively, and (d) other miscellaneous international investment sales for
proceeds of $17. Domestic sales were comprised of the sale of shares of TCG, for
net proceeds of $678, shares of Time Warner, for net proceeds of $220, and
miscellaneous asset sales, for proceeds of $33.

DEBT ACTIVITY
 
    Total debt at December 31, 1998 was $5,422, a decrease of $3,541 compared
with December 31, 1997. Debt at December 31, 1998 includes debt related to the
capital assets segment which is now shown in the Consolidated Balance Sheet of
the Company. Prior to this time, the accounts of the capital assets segment had
been accounted for as discontinued operations and netted on the Consolidated
Balance Sheet into one line labeled "net investment in assets held for sale."
See Note 23--Net Investment in Assets Held For Sale--to the Consolidated
Financial Statements. MediaOne Group's percentage of debt to total capital at
December 31, 1998 was 26.5 percent compared with 41.8 percent at December 31,
1997. Including debt associated with the capital assets segment for both 1998
and 1997, Preferred Securities, the minority interest in Centaur and preferred
stock subject to mandatory redemption as components of debt, MediaOne Group's
percentage of debt to total capital at December 31, 1998, was 37.5 percent
compared with 48.1 percent at December 31, 1997.
 
    On December 15, 1998, Centaur issued three series of preferred shares for
total net proceeds of $1,099, net of issuance costs of $31. Dividend and
redemption payments on certain of the preferred shares may only be made to the
extent AirTouch pays dividends or redeems its outstanding preferred shares held
by the Company. See Note 13--Minority Interest in Centaur Funding--to the
Consolidated Financial Statements. Proceeds from the issuance of the preferred
shares were loaned to a subsidiary of the Company and used for general corporate
purposes.
 
    In October 1998, MediaOne Group issued $500 of 9.04 percent Preferred
Securities for net proceeds of $484. The proceeds from the issuance were used to
redeem outstanding commercial paper and for general corporate purposes. MediaOne
Group guarantees the payment of interest and redemption amounts to holders of
the Preferred Securities.
 
    During August and September, 1998, MediaOne Group issued approximately
$1,686 of 6.25 percent exchangeable notes for net proceeds of $1,642. The notes
mature on August 15, 2001 and are mandatorily redeemable at MediaOne Group's
option into (i) shares of AirTouch common stock held by MediaOne Group, (ii) the
cash equivalent, or (iii) a combination of cash and AirTouch common stock. The
number of shares of AirTouch common stock to be exchanged for each exchangeable
note, and/or the cash equivalent, varies based upon the fair value of the
AirTouch common stock.
 
    In December 1998, MediaOne Group also redeemed debt exchangeable into common
stock ("DECS") originally issued in 1995. Such DECS were redeemed with shares of
Enhance Financial Services Group, Inc., held by the Company. See Note
10--Debt--to the Consolidated Financial Statements.
 
    On June 12, 1998, MediaOne Group tendered $4.9 billion notional amount of
long term debt. Also on June 12, 1998, MediaOne Group tendered for cash $301
face value of the 7.96 percent Preferred Securities and $237 face value of the
8.25 percent Preferred Securities originally issued in 1995 and 1996,
respectively. The cash redemption amount of $5.5 billion for the long term debt
and $582 for the Preferred Securities was financed with floating-rate commercial
paper with a weighted average interest rate of 5.85 percent. In addition, in
accordance with the terms of the Separation Agreement, New U S WEST funded to
MediaOne Group $3.9 billion related to the Dex Alignment. Such funds were used
to repay a portion of the commercial paper issued in connection with the
Refinancing.
 
    During 1997, the Company redeemed its zero coupon subordinated notes, which
had a recorded value of $268. In addition, MediaOne redeemed a 10.625 percent
senior subordinated note with a recorded value
 
                                       29
<PAGE>
of $110, including a premium of $10. The Company financed both redemptions with
floating-rate commercial paper.
 
    In June 1997, the Company acquired cable systems serving approximately
40,000 subscribers in Michigan for cash of $25 and the issuance of approximately
$50 in liquidation value of Old U S WEST Series E Preferred Stock (the "Series E
Preferred Stock"). Effective with the Separation, the Series E Preferred Stock
remains outstanding and represents shares of Series E Preferred Stock of
MediaOne Group. The Series E Preferred Stock is redeemable at the Company's
option beginning five years from the date of issuance. The stockholders have the
right to elect cash upon redemption, or to convert their shares into MediaOne
Group Stock based on a predetermined formula.
 
    In 1996, Old U S WEST issued $254 of exchangeable notes, or DECS, due May
15, 1999. Effective with the Separation, the DECS became the obligation of
MediaOne Group. Upon maturity, each such DECS will be exchanged by MediaOne
Group for shares of common stock of Financial Security Assurance Holdings Ltd.
("FSA") held by the Company or, at the Company's option, redeemed at the cash
equivalent.
 
    On October 29, 1996, Old U S WEST refinanced commercial paper through the
issuance of 8.25 percent Preferred Securities totaling $480. In connection with
the Separation, the Company redeemed for cash and exchanged $450 face value of
such Preferred Securities. See Note 14--Preferred Securities--to the
Consolidated Financial Statements.

(1) In February 1999, Standard & Poor's announced a methodology change for the
    rating of Preferred Securities and other similar instruments which is
    reflected above. This change is not a credit event.
 
    As a result of the announcement on March 22, 1999 of the proposed merger of
MediaOne Group with Comcast Corporation, the Company's debt and Preferred
Securities were placed on credit watch by Standard & Poor's with negative
implications, and by Moody's with direction uncertain. See Note 22-- Subsequent
Events--to the Consolidated Financial Statements.
 
    The Centaur preferred shares Series B and C were placed under review for a
possible upgrade by Moody's as a result of actions on AirTouch credit.

DIVIDENDS
 
    The Company paid dividends on the Communications Stock totaling $519, $992
and $939 in 1998, 1997 and 1996, respectively. MediaOne Group no longer pays
dividends on the Communications Stock as it has been canceled effective June 12,
1998, as a result of the Separation.
 
CASH FROM DISCONTINUED OPERATIONS
 
    Cash from discontinued operations was $4,953 through the date of the
Separation, and $1,091 and $1,149 in 1997 and 1996, respectively. Such amounts
consisted primarily of fundings to MediaOne Group for common dividends paid to
Communications Stock shareowners, dividends paid by Dex to MediaOne Group,
proceeds from the issuance of Communications Stock, and debt fundings and
repayments between MediaOne Group and New U S WEST. Also included in the 1998
amounts were the $3.9 billion of debt assumed by New U S WEST in connection with
the Dex Alignment, as well as $152 of net costs reimbursed to MediaOne Group as
a result of the Separation and the Refinancing. The $3.9 billion payment by New
U S WEST was used by MediaOne Group to repay commercial paper issued in the
Refinancing.
 
OTHER FINANCING ACTIVITIES
 
    COMMITMENTS AND DEBT GUARANTEES.  At December 31, 1998, MediaOne Group's
commitments and debt guarantees associated with its international and domestic
investments totaled approximately $310 and $240, respectively. In addition, a
MediaOne Group subsidiary guarantees debt, nonrecourse to the Company,
associated with its international investment in the principal amount of
approximately $880.
 
    DEBT FACILITIES.  In May 1998, MediaOne Group entered into 365-day and
5-year revolving bank credit facilities totaling $4.0 billion to support its
commercial paper program and to provide financing in conjunction with the
refinancing of substantially all of the indebtedness issued or guaranteed by Old
U S WEST. The facilities were reduced in December 1998 to a total capacity of
$3.0 billion. As of December 31, 1998, $2.8 billion was available on the
facilities.
 
    SHELF REGISTRATIONS.  Under registration statements filed with the
Securities and Exchange Commission as of November 4, 1998, the Company was
permitted to issue up to approximately $400 of new debt securities.
 
    SHARE REPURCHASE.  On August 7, 1998, the Board of Directors of MediaOne
Group authorized the repurchase of up to 25 million shares of the Company's
common stock. The shares may be repurchased over the next three years, dependent
on market and financial conditions. During 1998, MediaOne Group purchased and
placed into treasury approximately 8,682,000 shares of MediaOne Group Stock for
a total costs basis of $352. Prior to the Separation, Old U S WEST purchased and
placed into treasury $31 of Communications Stock. All outstanding shares of
Communications Stock held as treasury stock by Old U S WEST were canceled as of
the Separation date.
 
RISK MANAGEMENT
 
    MediaOne Group is exposed to market risks arising from changes in interest
rates, foreign exchange rates and equity prices. Derivative financial
instruments are used to selectively manage these risks. MediaOne Group does not
use derivative financial instruments for trading purposes. The following
discussion does not include any impact from the Company's investment in Cable &
Wireless Optus Limited and options related to the sale of this investment since
it was sold during the first quarter of 1999. See Note 22--Subsequent Events--to
the Consolidated Financial Statements.
 
    INTEREST RATE RISK MANAGEMENT.  MediaOne Group is exposed to interest rate
risk from the investment in AirTouch preferred stock and other debt securities,
and debt issued by the Company. MediaOne Group historically entered into
interest rate swaps to minimize interest rate variability on floating rate debt,
and
 
                                       31
<PAGE>
interest rate swaps and options to protect the value of the AirTouch preferred
stock. As of December 31, 1998, the Company had no outstanding interest rate
contracts.
 
    Approximately $280 of MediaOne Group's debt is subject to changes in
interest rates. A hypothetical 10 percent increase in interest rates would
decrease the annual earnings of MediaOne Group by $1.
 
    FOREIGN EXCHANGE RISK MANAGEMENT.  MediaOne Group selectively enters into
forward and option contracts to manage the market risks associated with
fluctuation in foreign exchange rates after considering offsetting foreign
exposures among international operations. The use of forward and option
contracts allows MediaOne Group to fix or cap the cost of firm foreign
investment commitments, the amount of foreign currency proceeds from sales of
foreign investments, the repayment of foreign currency denominated receivables
and the repatriation of dividends. The market values of foreign exchange
positions, including the hedging instruments, are continuously monitored and
compared with predetermined levels of acceptable risk. All foreign exchange
contracts have maturities of one year or less. As of December 31, 1998, the
market value of foreign exchange contracts outstanding was not material.
 
    MediaOne Group is exposed to foreign exchange risk associated with its cash
deposits, notes receivable and payable, and a cost method investment denominated
in a foreign currency. As of December 31, 1998, MediaOne Group had British
pound-denominated notes receivable and cash deposits in the translated amount of
$186, a British pound-denominated investment in marketable equity securities in
the translated amount of $106, a Czech Koruna-denominated note receivable and
cash deposits in the translated amount of $33, and a Czech Koruna-denominated
note payable in the translated amount of $30.
 
    A hypothetical 10 percent adverse change in the British Pound and Czech
Koruna exchange rates as compared with the U.S. dollar would reduce the market
value of the cash deposits, investment and notes payable and receivable by $30
as of December 31, 1998.
 
    EQUITY-PRICE RISK MANAGEMENT.  MediaOne Group is exposed to market risks
associated with equity security prices related to its investments in marketable
equity securities. On a selective basis, MediaOne Group enters into option
contracts and exchangeable debt instruments to manage risks associated with
fluctuations in equity security prices.
 
    The table below presents the impact of hypothetical movements in the equity
security prices related to MediaOne Group's combined position in marketable
equity securities and derivative contracts. The hypothetical change in stock
price movements for AirTouch and Internet related investments are based upon
stock price movements since December 31, 1998 and historical stock prices,
respectively.

</TABLE>
 
------------------------
 
(1) See Note 10--Debt--to the Consolidated Financial Statements.
 
    The increase in the Company's exposure to equity price risk in 1998 is
primarily due to the receipt of AirTouch common shares in the AirTouch
Transaction, partially offset by the issuance of the Exchangeable Notes.

    The changes in interest rates, foreign exchange rates and equity security
prices are based on hypothetical movements in future market rates and are not
necessarily indicative of actual results that may occur. Future gains and losses
will be affected by actual changes in interest rates, foreign exchange rates,
equity security prices, and changes in derivative financial instruments employed
during the year.
 
COMPETITIVE AND REGULATORY ENVIRONMENT
 
    CABLE AND BROADBAND--DOMESTIC.  MediaOne Group's cable television systems
generally compete with other providers of video programming for viewer attention
and advertising dollars. Competitors include service providers such as
television broadcasters, DBS, multipoint multichannel distributions services
("MMDS"), local multipoint distribution services ("LMDS"), satellite master
antenna service ("SMATV"), video tape rentals stores, movie theaters and live
sporting events. In addition, as a result of the Telecommunications Act of 1996
(the "Telecommunications Act") certain local exchange carriers ("LECs"),
including Regional Bell Operating Companies ("RBOCs"), are beginning to offer
video programming in competition with the Company's cable services. The
competition faced by the Company's cable systems is likely to increase in the
future with the development and growth of new technologies.
 
    As MediaOne Group continues to offer additional services over its hybrid
fiber-coax ("HFC") networks, MediaOne Group will face additional competition.
Both the HSD and telephone services offered by MediaOne Group will face
competition from other providers, including RBOCs and other incumbent LECs,
interexchange carriers ("IXCs"), Internet service providers ("ISPs") and other
providers of local exchange and on-line services. The degree of competition will
be dependent upon the state and federal regulations concerning entry,
interconnection requirements and the degree of unbundling of the incumbent LECs'
networks. Competition will be based upon product, service quality, breadth of
services offered, and to a lesser extent on price.
 
    The products and services of the Company are subject to varying degrees of
regulation. Under the Telecommunications Act, it is anticipated that the
regulation of all but basic tier cable and equipment rates will be discontinued
effective March 31, 1999. However, as described below, the Company must seek the
Federal Communications Commission's ("FCC") permission to end rate regulation
for cable systems covered by Continental's Social Contract. The
Telecommunications Act also eliminated certain cross-ownership restrictions
among cable operations, broadcasters and MMDS operations and removed barriers to
competition with LECs.
 
    The Cable Television Consumer Protection and Competition Act of 1992 (the
"1992 Cable Act") provided for the regulation of rates for certain cable
television services and for equipment and installation charges. The FCC was
charged with setting the standards for rate regulation, but also approved
"social contracts" as an alternative form of regulation. Continental's Social
Contract was the first approved by the FCC. The Social Contract is a six-year
agreement covering most of Continental's franchises and settled all of
Continental's outstanding rate complaints. As part of the Social Contract,
Continental agreed to, among other things, invest at least $1.7 billion in
domestic system rebuilds and upgrades through the year 2000 to expand channel
capacity and improve system reliability and picture quality. As of December 31,
1998, the investment commitment had been met; however, the Company must still
upgrade all systems covered by the Social Contract to a minimum of 550MHz, with
at least half being upgraded to 750 MHz. The Social Contract also provides that,
if the laws and regulations applicable to services offered in any MediaOne
franchise change in a manner that would have a material favorable financial
impact on MediaOne, the Company may petition the FCC to terminate the Social
Contract. The sunset of rate regulation for the upper tiers of cable service
represents such a change and the FCC may not unreasonably refuse to terminate
the rate regulation provision of the Social Contract.
 
    Cable television systems are also subject to local regulation, typically
imposed through the franchising process. Local officials may be involved in the
initial franchise selection, franchise service area, construction standards,
safety, rate regulation of the lowest tier of service and equipment and
installation rates,
 
                                       33
<PAGE>
customer service standards, billing practices, community-related programming and
services, franchise renewal and imposition of franchise fees.
 
    In June, 1998, the FCC issued formal rules providing for the retail sale of
set-top television boxes which integrate security and non-security functions. On
January 1, 2005, cable companies will no longer be permitted to sell or lease
new integrated boxes to their subscribers. In addition, cable companies must
provide subscribers with related security modules that plug into set-top boxes
that are purchased from consumer electronics retailers by July 1, 2000. In
February 1999, MediaOne Group partnered with various manufacturers of digital
set-top boxes in order to provide an open conditional access system, which would
be compliant with domestic OpenCable-TM- specifications.
 
    INTERNATIONAL.  The Company's international broadband and wireless
communications businesses also face significant competition in their respective
markets. Telewest's cable television services compete with broadcast television
stations, DBS services, satellite master antenna service systems and certain
narrowband operators in the United Kingdom. Telewest's telecommunications
services compete with domestic telephone companies in the United Kingdom, such
as British Telecommunications plc. One 2 One competes with three cellular
operators in the United Kingdom. Competition is based upon price, geographic
coverage and the quality of the services offered. The wireless businesses in
Central Europe face similar competition.
 
CONTINGENCIES
 
    Certain cable subsidiaries of the Company in Florida, Michigan, Minnesota
and Ohio have been named as defendants in various class action lawsuits
challenging such subsidiaries' policies for charging late payment fees when
customers fail to pay for subscriber services in a timely manner. MediaOne Group
is currently reviewing the lawsuits to determine what impact, if any, such
lawsuits may have on the operations of the Company.
 
YEAR 2000 READINESS
 
    The statements made herein relating to the Year 2000 are designated as Year
2000 Readiness Disclosures for purposes of the Year 2000 Information and
Readiness Disclosure Act. MediaOne Group uses software and related technologies
throughout its business that may be affected by the date change in the year
2000. MediaOne Group established a corporate-wide Year 2000 program in 1997,
which in relation to other business projects and objectives has been assigned a
high priority. The inability of systems to appropriately recognize the year 2000
could result in a disruption of Company operations. More specifically, such a
failure could result in material operational impacts on various of the Company's
business operations, as identified in more detail in the chart below.
 
    MediaOne Group is progressing through a comprehensive program to evaluate
and address the impact of the Year 2000 on its operations. MediaOne Group is
utilizing both internal and external resources in implementing the program. The
program consists of the following phases:
 
<TABLE>
<S>        <C>
Phase
(I)        Assessment--Structured evaluation, including a detailed inventory outlining the
           impact that the Year 2000 may have on current operations.
(II)       Detailed Plan--Establishment of priorities, development of specific action steps and
           allocation of resources to address the issues as outlined in Phase I.
(III)      Conversion--Implementation of the necessary changes, (i.e., repair, replacement or
           retirement) as outlined in Phase II.
(IV)       Testing--Verification that the conversions implemented in Phase III will be

    MediaOne Group currently has activities underway in each of the five phases.
The current stage of activities varies based upon the type of component, system,
and/or service at issue.
 
    MediaOne Group has identified three primary risk assessment levels for
various inventory items relative to the Year 2000 program. These levels are
high, medium and low, with high risk items being those that may have such an
impact on the business, that if the risk is not appropriately managed and/or
mitigated, the occurrence of the risk could have an adverse impact on the
operations of the business, its customers and its employees. Medium risks are
those that if they are not appropriately managed and/or mitigated, the
occurrence of the risk may cause major difficulties in managing the day-to-day
operations of the business, and/or have a significant impact on the ability to
deliver acceptable service to customers. Low risks are those that if they are
not appropriately managed and/or mitigated, the occurrence of the risk may cause
difficulties in managing the business, however should not severely impact
service delivery, cash flow, or critical management activities.
 
    MediaOne Group has identified and prioritized four critical business
functions across its business operations in order to manage its Year 2000
program. The critical business functions are (i) customer service, which
includes service delivery, service disruption, network management and workforce
management; (ii) customer care and billing, which includes bill issuance and
access to functioning call centers; (iii) cash flow, which includes payment
processing, general ledger, accounts payable and accounts receivable; and (iv)
employees, health and safety, which includes payroll processing, pension fund
issues, and building operations and security.
 
    MediaOne Group has identified two business areas that are subject to Year
2000 disclosures. These are Domestic Cable and Broadband, and Investments in
Unconsolidated Subsidiaries.

INVESTMENT IN UNCONSOLIDATED SUBSIDIARIES
 
    MediaOne Group has significant investments in both domestic and
international cable and broadband operations as well as wireless operations.
Within this area MediaOne Group has separated the Year 2000 program between
domestic and international investments for improved analysis and program
management.
 
(I) DOMESTIC INVESTMENTS
 
    The domestic investments include an investment in TWE, the second-largest
provider of cable television services in the United States. MediaOne Group also
holds a significant cost basis investment in AirTouch as a result of selling its
domestic wireless businesses to AirTouch on April 6, 1998.
 
    MediaOne Group continues to monitor Year 2000 efforts at TWE. TWE has
represented to MediaOne Group that they continue to be in the conversion phase
of their Year 2000 program as of December 31, 1998. MediaOne Group is planning
to continue the audit of TWE and its progress relative to its Year 2000 program
during 1999, as deemed necessary. MediaOne Group will continue to monitor
information provided to the investor community by AirTouch to evaluate the
progress toward remediation of Year 2000 issues and to monitor MediaOne Group's
investment value.
 
(II) INTERNATIONAL INVESTMENTS
 
    Internationally, MediaOne Group holds an investment in Telewest, the largest
provider of combined cable and broadband communications services in the United
Kingdom. MediaOne Group also holds interests in cable and broadband properties
in the Netherlands, Belgium, the Czech Republic, Japan and Singapore.
Additionally, MediaOne Group holds wireless interests which include a 50 percent
joint venture interest in One 2 One, a provider of PCS services in the United
Kingdom. MediaOne Group also
 
                                       36
<PAGE>
owns interests in wireless properties in Hungary, the Czech and Slovak
Republics, Poland, Russia and India.
 
    All of the fourteen key international ventures in which MediaOne Group has
an investment continue to be in the Conversion and Testing Phases. The current
stage of activities varies within each venture as well as upon the type of
component at issue. Based upon current information provided by the ventures to
MediaOne Group, costs of addressing potential problems are not expected to have
a material adverse impact on MediaOne Group's financial position.
 
THIRD PARTY RELATIONSHIPS
 
    MediaOne Group has significant relationships and dependencies with regard to
systems and technology provided and supported by third party vendors and service
providers. As part of its Year 2000 program, MediaOne Group has established a
vendor compliance group to obtain formal Year 2000 compliance representation
from vendors who provide products and services to MediaOne Group. The scope of
this group includes vendors who provide information technologies, network
switching and elements, infrastructure, electronic trading partners and other
third party suppliers. The vendor compliance process is being performed
concurrently with the regional/business unit Year 2000 remediation activities.
In addition, the MediaOne Group Year 2000 legal team has established in parallel
a vendor contract analysis program. Because of the aforementioned reliance
placed on third party vendors, MediaOne Group's estimate of costs to be incurred
could change substantially should one or more of the vendors be unable to timely
deliver Year 2000 compliant products.
 
BUSINESS CONTINUITY
 
    Business continuity teams are in place for the Year 2000 program and include
business contingency and response and recovery management. Initial contingency
plans for mission critical projects that had not completed testing by December
31, 1998 have been developed that include trigger dates and processes for
implementation of such plans if needed. Operational response and recovery plans
are being refined and expected to be in place by third quarter 1999. There can
be no assurance that the contingency plans developed by the Company will
eliminate all potential for service interruption.
 
COSTS OF YEAR 2000 PROGRAM
 
    MediaOne Group has incurred approximately $22 of costs to implement its Year
2000 compliance program through the fourth quarter of 1998 and currently expects
to incur between $60 to $75 of costs in aggregate, of which $10 to $15 represent
capitalized expenditures. Of the total costs being incurred, approximately $50
to $65 are incremental to MediaOne Group. The funding of these costs will be
managed by the Company through its liquidity and capital resources plan.
 
RISKS ASSOCIATED WITH YEAR 2000 ISSUES
 
    Due to the complexity of the issues presented by the Year 2000 and the
proposed solutions, and the interdependence of MediaOne Group on a global list
of third party suppliers, it is impossible to assess with any degree of accuracy
the impact of a failure in any one aspect or combination of aspects of the
Company's Year 2000 program in relation to the Company's critical business
function areas. MediaOne Group cannot provide assurance that actual results will
not differ from management's estimates due to the complexity of correcting the
systems and related technologies surrounding the Year 2000 issue.
 
    Failure by MediaOne Group to complete its Year 2000 project in a timely or
complete manner, within its estimate of projected costs, or failure by third
parties, such as financial institutions and related networks, software
providers, local telephone companies, long distance providers, power providers,
etc., to correct their systems, with which MediaOne Group's systems
interconnect, could have a material impact on future results of operations and
financial position. Other factors which might cause a material difference from
management's estimate would include, but not be limited to, the availability and
cost of
 
                                       37
<PAGE>
personnel with appropriate skills and abilities to locate and correct all
relevant computer code and similar uncertainties, as well as the collateral
effects on MediaOne Group of the Year 2000 problem on the economy in general, or
on MediaOne Group's business partners and customers in particular. However,
MediaOne Group believes that the Year 2000 issue can be mitigated through its
planned repair, replacement, or retirement of the relevant systems and related
technologies, that are within MediaOne Groups reasonable control.
 
FUTURE IMPLEMENTATION OF NEW ACCOUNTING STANDARDS
 
    In the year 2000, the Company will adopt SFAS No. 133, "Accounting for
Derivative Instruments and for Hedging Activities." This statement establishes
accounting and reporting standards for derivative instruments and for hedging
activities. Among other things, the statement requires that an entity recognize
all derivative instruments on the balance sheet as either assets or liabilities,
and to account for those instruments at fair value. The Company is evaluating
the impact of SFAS No. 133.
 
    Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," was issued in March 1998. SOP
98-1, among other things, requires that certain costs of internal use software,
whether purchased or developed internally, be capitalized and amortized over the
estimated useful life of the software. Adoption of SOP 98-1 is required as of
January 1, 1999 and will not have a material impact on the results of operations
of the Company.
 
    SOP 98-5, "Reporting on the Costs of Start-Up Activities," was issued in
April 1998. SOP 98-5 requires, among other things, that the costs related to
start-up activities of a new entity, facility, product or service be expensed.
Adoption of SOP 98-5 is required as of January 1, 1999, and will not have a
material impact on the results of operations of the Company.
 
OUTLOOK
 
    The outlook section contains "forward looking information" within the
meaning of the Private Securities Litigation Reform Act of 1995. Although
MediaOne Group believes that its expectations are based on reasonable
assumptions within the bounds of its knowledge of its business and operations,
there can be no assurance that actual results will not differ materially from
its expectations. For a detailed listing of factors that could cause actual
results to differ from the Company's expectations, see the "Safe Harbor
Language" on page 14, incorporated herein by reference.
 
DOMESTIC CABLE AND BROADBAND BUSINESS
 
    The following expectations are based on the cable systems held as of
December 31, 1998, and could be impacted by cable system acquisitions,
dispositions or trades.
 
    CONSOLIDATED REVENUES.  The Company expects total revenue growth around 10
percent during 1999. Total revenue includes video, HSD, telephony and other
services. Revenue growth will be driven by the following:
 
 (i) Basic cable revenues--The Company anticipates average rate increases for
     its basic cable services to be no higher than five percent in 1999.
 
 (ii) Subscriber growth--As of year-end 1999, subscriber growth is expected to
      be around 1.5 percent, on a comparable basis.
 
 (iii) Premium services revenues--The negative trend in premium services
       revenues is expected to reverse during 1999 as a result of the
       introduction of "NexTV", a packaging proposition which focuses on
       clustering related premium channels.
 
 (iv) Pay per view revenues--Various sporting events in 1999 are expected to
      generate increased revenues over 1998 and reverse the overall decrease in
      this category.
 
                                       38
<PAGE>
 (v) Advertising revenues--MediaOne Group expects growth of approximately 20
     percent in advertising revenues during 1999.
 
 (vi) HSD revenues--The Company expects to increase its HSD customers by upwards
      of 100,000 during 1999.
 
 (vii) Telephony revenues--The telephony customer base is expected to more than
       triple by year-end 1999.
 
    CONSOLIDATED EBITDA.  EBITDA growth is expected to be approximately five
percent in 1999. The Company anticipates double digit EBITDA growth by the year
2000. New Products are expected to incur total losses of $55 during 1999 as a
result of reduced EBITDA losses for HSD services, offset by increased EBITDA
losses for telephony services. The Company is also working on a number of
different initiatives to improve service and add to the domestic cable business
capabilities. The costs of such initiatives are expected to amount to
approximately $55 in each of 1999 and 2000.
 
    TIME WARNER ENTERTAINMENT.  The Company's investment in Time Warner
Entertainment continues to increase in value. Cash distributions from this asset
are expected in the foreseeable future.
 
INTERNATIONAL BUSINESS
 
    The Company expects to approximately double proportionate EBITDA from its
international ventures in 1999. MediaOne Group continues to focus on high-growth
ventures. Management's expectations are to continue making select investments in
Europe and Asia as opportunities arise, to extract value from its international
ventures when they reach peak levels, and to exit those ventures in which it
cannot obtain an acceptable level of control.
 
    In the third quarter of 1998, Russia experienced a political and economic
crisis which had a significant detrimental impact on the business climate. As a
result of the crisis, the Company conducted an evaluation of its investments in
Russia which are held by RTDC, a 66.5 percent owned subsidiary. The Company
concluded that the investments held by RTDC, although impacted by the crisis,
were not impaired at the present time. The future prospects for the Russian
economy are unknown. Although predictions vary, the political or economic
climate of Russia may decline further and could result in a change in the
assessment of its investments. As of December 31, 1998, the Company had a net
investment in RTDC of $11, a net receivable from the venture of $9, and an
outstanding guarantee of RTDC debt of $17.
 
    The company owns a 49 percent interest in BPL Cellular Limited ("BPL
Cellular"), a wireless venture which provides cellular telephone service in
certain areas of India. In 1998, BPL Cellular made only partial payments on its
cellular license due to the India government. In recent months, the government
has indicated a willingness to re-examine its regulations applicable to cellular
carriers, including the license fee structure. BPL Cellular will require cash
from external sources to fund its operations in 1999 and is currently in
negotiations with banks regarding its interim and long-term financing needs. As
of December 31, 1998, the Company had a net investment in BPL Cellular of a
negative $53. The Company has recorded losses in excess of its capital
contributions due to outstanding loan guarantees of BPL Cellular's debt of
approximately $86. The Company also has an outstanding receivable from BPL
Cellular of $10.
 
                                * * * * * * * *
 
    MediaOne Group from time to time engages in preliminary discussions
regarding restructurings, dispositions and other similar transactions. Any such
transaction may include, among other things, the transfer of certain assets,
businesses or interests, or the incurrence or assumption of indebtedness, and
could be material to the financial condition and results of operations of the
Company. There is no assurance that any such discussions will result in the
consummation of any such transaction.

------------------------
 
(1) The proportionate results are based on MediaOne Group's 25.51 percent pro
    rata priority and residual equity interests in reported Time Warner
    Entertainment Company L.P. ("TWE") results. The reported TWE results are
    prepared in accordance with GAAP and have not been adjusted to report TWE
    results on a proportionate basis.
 
    Normalized for the one-time effects of acquisitions, dispositions and other
asset transactions, proportionate revenues increased $961, or 15.7 percent, and
EBITDA increased $317, or 20.7 percent.
 
    CABLE AND BROADBAND--DOMESTIC.  During 1998, normalized for the one-time
effects of cable system acquisitions and dispositions, and a change in
classification of the domestic cable late fee revenues, proportionate revenues
increased $538, or 10.7 percent. This is a result of increases in subscribers
and revenue per subscriber mainly due to expanded channel offerings, repackaging
of services and increased rates. Normalized for the one-time effects of cable
system acquisitions and dispositions, proportionate EBITDA increased $123, or
7.7 percent. This increase is primarily a result of higher revenues, partially
offset by higher programming fees, increased personnel costs related to customer
service initiatives and costs associated with the deployment of HSD and
telephony services. Proportionate EBITDA related to TWE operations increased
12.1 percent. TWE's results benefited from improved cable, programming and
filmed entertainment operations, and gains realized by asset sales.
 
    CABLE AND BROADBAND--INTERNATIONAL.  During 1998, normalized for asset
dispositions and the suspended proportionate reporting of the Malaysian and
Indonesian ventures in 1998, international cable and broadband proportionate
revenues increased $61, or 21.9 percent, due primarily to customer growth at
Telewest. During the same period, normalized proportionate EBITDA increased $32,
to a positive $21 in proportionate EBITDA, due to improved operations at
Telewest, partially offset by an increase in MediaOne Group international staff
costs.
 
    Proportionate international cable subscribers totaled 993,000 at December
31, 1998, a 7.2 percent increase over last year on a comparable basis.
Telewest's cable television subscribers increased 13.4 percent over last year on
a comparable basis.
 
    INTERNATIONAL WIRELESS.  During 1998, proportionate revenues and EBITDA for
the international wireless operations increased due to the 80.1 percent increase
in the international wireless subscriber base to 1,734,000, on a comparable
basis. One 2 One, the PCS venture in the United Kingdom, and the digital
wireless operations in Hungary, Czech Republic, Slovakia, and Poland contributed
significantly to the increase. One 2 One added 454,000 proportionate customers,
a 90 percent increase from a year ago.

SELECTED PROPORTIONATE FINANCIAL DATA (CONTINUED)
    CORPORATE.  During 1998, proportionate revenues for corporate operations
increased $3, or 17.6 percent, to $20. Proportionate EBITDA losses decreased
$11, or 13.8 percent, to $(69) primarily due to a $30 charge in 1997 for
management changes and moving costs related to relocating MediaOne's operations
from Boston to Denver, partially offset by increased overhead costs.
 
    OTHER.  Other reflects the results of the international directories
operations located in South America in both 1998 and 1997, and in Poland and the
United Kingdom in 1997. Also included are costs related to development
activities, primarily for the development of Internet content services.
Proportionate revenues decreased $49 during 1998, primarily due to the sale of
the United Kingdom and Poland international directories operations in the latter
part of 1997. Proportionate EBITDA increased $19 during 1998, primarily due to
the July 1998 transfer of an Internet content service operation to the domestic
cable and broadband operation, and to the sale in 1997 of the international
directories operations discussed above.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS AND SHAREOWNERS OF MEDIAONE GROUP, INC.:
 
    We have audited the accompanying Consolidated Balance Sheets of MediaOne
Group, Inc. (a Delaware corporation) and subsidiaries as of December 31, 1998
and 1997, and the related Consolidated Statements of Operations, Shareowners'
Equity and Cash Flows for each of the three years in the period ended December
31, 1998. These consolidated financial statements and the schedule referred to
below are the responsibility of the Company's management. Our responsibility is
to express an opinion on these consolidated financial statements and this
schedule based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of MediaOne Group,
Inc. and subsidiaries as of December 31, 1998 and 1997, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1998, in conformity with generally accepted
accounting principles.
 
    Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule appearing on page S-1 of
this Form 10-K is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic financial statements.
This schedule has been subjected to the auditing procedures applied in the audit
of the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

    The Consolidated Financial Statements of MediaOne Group have been prepared
in conformity with generally accepted accounting principles applied on a
consistent basis. The integrity and objectivity of information in these
financial statements, including estimates and judgments, are the responsibility
of management, as is all other financial information included in this report.
 
    MediaOne Group maintains a system of internal accounting controls designed
to provide reasonable assurance as to the integrity and reliability of financial
statements, the safeguarding of assets and the prevention and detection of
material errors or fraudulent financial reporting. Monitoring of such systems
includes an internal audit program designed to objectively assess the
effectiveness of internal controls and recommend improvements therein.
 
    Limitations exist in any system of internal accounting controls based upon
the recognition that the cost of the system should not exceed the benefits
derived. MediaOne Group believes that the Company's system does provide
reasonable assurance that transactions are executed in accordance with
management's general or specific authorizations and is adequate to accomplish
the stated objectives.
 
    The independent certified public accountants, whose report is included
herein, were engaged to express an opinion on our Consolidated Financial
Statements. Their opinion is based on procedures performed in accordance with
generally accepted auditing standards, including examining, on a test basis,
evidence supporting the amounts and disclosures in the Consolidated Financial
Statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
 
    In an attempt to assure objectivity, the financial information contained in
this report is subject to review by the Audit Committee of the Board of
Directors. The Audit Committee is composed of outside directors who meet
regularly with management, internal auditors and independent auditors to review
financial reporting matters, the scope of audit activities and the resolution of
audit findings.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
                (DOLLARS IN MILLIONS, EXCEPT PER SHARE AMOUNTS)
 
NOTE 1: THE SEPARATION
 
    Prior to June 12, 1998, MediaOne Group, Inc. ("MediaOne Group" or the
"Company") was known as "U S WEST, Inc." ("Old U S WEST"). On June 12, 1998, Old
U S WEST separated its businesses into two independent public companies (the
"Separation"). Until the Separation, Old U S WEST conducted its businesses
through two groups: U S WEST Media Group (the "Media Group") and U S WEST
Communications Group (the "Communications Group"). Upon Separation, Old U S WEST
was renamed "MediaOne Group, Inc." and retained the multimedia businesses of
Media Group, except for U S WEST Dex, Inc. ("Dex"), the domestic directory
business. The telecommunications businesses of the Communications Group became
an independent public company and retained the "U S WEST, Inc." name ("New U S
WEST"). In addition, Dex was aligned with New U S WEST (the "Dex Alignment").
 
    The Separation was consummated pursuant to the terms of a separation
agreement between MediaOne Group and New U S WEST (the "Separation Agreement").
The Company accounted for the distribution of New U S WEST stock to the
Communications Group stockholders, and to the Media Group stockholders for the
Dex Alignment, as a discontinuance of the businesses comprising New U S WEST. As
a result, certain financial information of Old U S WEST has been restated to
give effect to the classification of New U S WEST as a discontinued operation.
See Note 24--Discontinued Operations--to the Consolidated Financial Statements.
 
    Prior to the Separation, Old U S WEST had outstanding two separate classes
of common stock which reflected the performance of its two groups. The
performance of Media Group was reflected by the U S WEST Media Group common
stock (the "Media Stock") and the performance of the Communications Group was
reflected by the U S WEST Communications Group common stock (the "Communications
Stock"). Upon Separation, and in accordance with the Separation Agreement, each
outstanding share of Media Stock remains outstanding and represents one share of
MediaOne Group common stock ("MediaOne Group Stock"). Each issued and
outstanding share of Communications Stock was redeemed for one share of New U S
WEST common stock. See Note 16--Shareowners' Equity--to the Consolidated
Financial Statements.
 
    In connection with the Dex Alignment, (i) each holder of Media Stock
received as a dividend .02731 shares of New U S WEST common stock for each share
of Media Stock held (the "Dex Dividend"), and (ii) $3.9 billion of Old U S WEST
debt was refinanced by New U S WEST.
 
    In connection with the Separation, MediaOne Group refinanced substantially
all of the indebtedness issued or guaranteed by Old U S WEST through a
combination of tender offers, prepayments and consent solicitations (the
"Refinancing"). See Note 10--Debt--to the Consolidated Financial Statements.

Entertainment Company, L.P. ("TWE" or "Time Warner Entertainment"), which
provides cable programming, filmed entertainment and broadband communications

plc ("Telewest"), the largest provider of residential cable, telephone and
Internet access services in the United Kingdom.
 
NOTE 3: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BASIS OF PRESENTATION.  The Consolidated Financial Statements include the
accounts of the Company and its majority-owned subsidiaries. Effective on
December 31, 1998, the Consolidated Balance Sheet includes the accounts of the
capital assets segment. Prior to this time, the capital assets segment had been
reported as "net investment in assets held for sale." See Note 23--Net
Investment In Assets Held For Sale--to the Consolidated Financial Statements.
All significant intercompany amounts and transactions within continuing
operations have been eliminated. Investments in less than majority-owned
ventures are generally accounted for using the equity method.
 
    Certain reclassifications within the Consolidated Financial Statements have
been made to conform to the current year presentation.
 
    USE OF ESTIMATES.  The preparation of financial statements in conformity
with generally accepted accounting principles ("GAAP") requires management to
make estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
    CASH AND CASH EQUIVALENTS.  Cash and cash equivalents include highly liquid
investments with original maturities of three months or less that are readily
convertible into cash and are not subject to significant risk from fluctuations
in interest rates.
 
    PROPERTY, PLANT AND EQUIPMENT.  The investment in property, plant and
equipment, including construction materials, is carried at cost less accumulated
depreciation. Additions, replacements and substantial betterments are
capitalized. Costs for normal repair and maintenance of property, plant and
equipment are expensed as incurred.
 
    MediaOne of Delaware, Inc. ("MediaOne"), the domestic cable and broadband
subsidiary of the Company, provides for depreciation of certain property, plant
and equipment using various straight-line group methods and remaining economic
lives. When depreciable property, plant and equipment accounted for on the group
methods is retired or sold, the original cost less the net salvage value is
generally charged to accumulated depreciation. The Company's remaining assets
are depreciated using the straight-line method. Gains or losses on disposal are
included in income.
 
    The Company depreciates buildings between 10 to 35 years, cable distribution
systems between 3 to 15 years, and general purpose computers and other between 3
to 20 years.
 
    Interest related to qualifying construction projects, including construction
projects of equity method investees, is capitalized and reflected as a reduction
of interest expense. Amounts capitalized were $19, $36 and $38 for the years
ended 1998, 1997 and 1996, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 3: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    COMPUTER SOFTWARE.  MediaOne capitalizes computer software, whether
purchased or developed internally. Capitalized software costs are amortized over
periods ranging up to 5 years. MediaOne Group expenses all other computer
software costs.
 
    Capitalized computer software of $89 and $24 at December 31, 1998 and 1997,
respectively, is recorded in property, plant and equipment. MediaOne amortized
capitalized computer software costs of $13, $10 and $1 in 1998, 1997 and 1996,
respectively.
 
    INTANGIBLE ASSETS.  Intangible assets are recorded when the cost of acquired
companies exceeds the fair value of their net tangible assets. The costs of
identified intangible assets and goodwill are amortized by the straight-line
method over periods ranging from 5 to 25 years. These assets are evaluated for
impairment with other related assets, using the methodology as prescribed by
Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of."
 
    INVESTMENTS IN DEBT AND EQUITY SECURITIES.  Debt and marketable equity
securities are classified as available for sale and are carried at fair market
value with unrealized gains and losses included in equity as a component of
other comprehensive income.
 
    FOREIGN CURRENCY TRANSLATION.  Assets and liabilities of international
subsidiaries and investments are translated at year-end exchange rates, and
income statement items are translated at average exchange rates for the year.
Resulting translation adjustments are included in equity as a component of other
comprehensive income. Gains and losses resulting from foreign currency
transactions are included in income.
 
    FINANCIAL INSTRUMENTS.  Synthetic instrument accounting is used for interest
rate swaps if the index, maturity, and amount of the instrument match the terms
of the underlying debt. Net interest accrued is recognized over the life of the
instruments as an adjustment to interest expense and is a component of cash
provided by operating activities. Any gain or loss on the termination of an
instrument that qualifies for synthetic instrument accounting would be deferred
and amortized over the remaining life of the original instrument.
 
    Deferral accounting is used for foreign currency forward and purchased
option contracts which qualify for and are designated as hedges of firm equity
investment commitments and for forward and purchased option contracts which
qualify as hedges of future debt issues or investments in debt and equity
securities. To qualify for deferral accounting, the contracts must have a high
inverse correlation to the exposure being hedged, and reduce the risk or
volatility associated with changes in foreign exchange rates, interest rates, or
equity prices. Qualified foreign exchange contracts are carried at market value
with gains and losses recorded in equity until sale of the investment. Qualified
interest rate contracts are associated with the related debt and amortized as
yield adjustments. Qualified interest rate and equity contracts associated with
investments in debt or equity securities are carried at market value, with gains
and losses recorded to the associated investment account. Any gain or loss on
the termination of a contract that qualifies for deferral accounting would be
deferred and accounted for with the underlying transaction being hedged. If a
contract does not maintain the required correlation with the hedged item,
deferral accounting is terminated and a gain or loss is recognized in the
Consolidated Statement of Operations for the difference between the change in
the fair value of the contract and the change in the fair value of the hedged
item.
 
    Market value accounting is used for derivative contracts which do not
qualify for synthetic instrument or hedge accounting. Market value accounting is
also used for foreign exchange contracts designated as

NOTE 3: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
hedges of foreign denominated receivables and payables. These contracts are
carried at market value in other assets or liabilities with gains and losses
recorded as other income or expense. The Company does not enter into derivative
financial instruments for trading purposes.
 
    STOCK OPTIONS.  MediaOne Group accounts for its stock incentive plans in
accordance with Accounting Principles Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees." The Company also follows the disclosure-only
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation." See Note
18--Stock Incentive Plans--to the Consolidated Financial Statements.
 
    REVENUE RECOGNITION.  Cable television, local telephone and high speed data
Internet access are generally billed monthly in advance, and revenues are
recognized the following month when services are provided. Revenues derived from
other cable television services, including pay-per-view and advertising, are
recognized as the service is provided.
 
    ADVERTISING COSTS.  Costs related to advertising are expensed as incurred.
Advertising expense was $114, $206 and $73 in 1998, 1997 and 1996, respectively.
 
    INCOME TAXES.  The provision for income taxes consists of an amount for
taxes currently payable or receivable and an amount for tax consequences
deferred to future periods.
 
    EARNINGS PER COMMON SHARE.  MediaOne Group computes basic and diluted
earnings per common share in accordance with SFAS No. 128, "Earnings Per Share."
See Note 17--Earnings Per Share--to the Consolidated Financial Statements.
Unless otherwise indicated, all per share amounts in the notes to the
Consolidated Financial Statements are computed based on basic weighted average
common shares outstanding.
 
    FUTURE IMPLEMENTATION OF NEW ACCOUNTING STANDARDS.  In the year 2000, the
Company will adopt SFAS No. 133, "Accounting for Derivative Instruments and for
Hedging Activities." This statement establishes accounting and reporting
standards for derivative instruments and for hedging activities. Among other
things, the statement requires that an entity recognize all derivative
instruments on the balance sheet as either assets or liabilities, and to account
for those instruments at fair value. The Company is evaluating the impact of
SFAS No. 133.
 
    Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," was issued in March 1998. SOP
98-1, among other things, requires that certain costs of internal use software,
whether purchased or developed internally, be capitalized and amortized over the
estimated useful life of the software. Adoption of SOP 98-1 is required as of
January 1, 1999 and will not have a material impact on the financial position or
results of operations of the Company.
 
    SOP 98-5, "Reporting on the Costs of Start-Up Activities," was issued in
April 1998. SOP 98-5 requires, among other things, that the costs related to
start-up activities of a new entity, facility, product or service be expensed.
Adoption of SOP 98-5 is required as of January 1, 1999 and will not have a
material impact on the results of operations of the Company.

NOTE 4: DOMESTIC ACQUISITIONS AND DISPOSITIONS
 
    AIRTOUCH COMMUNICATIONS.  On April 6, 1998, MediaOne Group sold its domestic
wireless businesses to AirTouch Communications, Inc. ("AirTouch") in a
tax-efficient transaction (the "AirTouch Transaction"). The AirTouch Transaction
was consummated pursuant to an agreement and plan of merger (the "AirTouch
Merger Agreement") dated as of January 29, 1998. The domestic wireless
businesses included cellular communication services provided to 2.6 million
customers in 12 western and midwestern states and a 25 percent interest in
PrimeCo Personal Communications, L.P. ("PrimeCo"). Pursuant to the AirTouch
Merger Agreement, AirTouch acquired these cellular and personal communications
services ("PCS") interests. Consideration under the AirTouch Transaction
consisted of (i) debt assumption of $1,350, (ii) the issuance to MediaOne Group
of $1,650 in liquidation preference of 5.143 percent dividend bearing AirTouch
preferred stock (fair value of $1,493), and (iii) the issuance to MediaOne Group
of 59,314,000 shares of AirTouch common stock. The transaction resulted in a
gain of $2,257, net of deferred taxes of $1,612.
 
    MediaOne Group accounts for its investment in AirTouch stock under the cost
method of accounting, as available for sale securities. The AirTouch preferred
stock is stated at fair value on the Consolidated Balance Sheet, in accordance
with SFAS No. 115, "Accounting for Certain Investments in Debt and Equity
Securities." To minimize MediaOne Group's exposure to fluctuations in the fair
value of the AirTouch preferred stock, the Company entered into an interest rate
swap agreement in April 1998 and an interest rate option agreement in October
1998. The interest rate swap agreement matured in October 1998, and the interest
rate option agreement in December 1998.
 
    During September 1998, the change in the value of the AirTouch preferred
stock and interest rate swap did not achieve the required correlation to
continue deferral accounting. Consequently, the Company recognized a net loss of
$31 (net of income tax benefits of $19) in other income for the change in the
fair value of the AirTouch preferred stock not offset by the fair value of the
interest rate swap agreement in accordance with SFAS No. 80, "Accounting for
Futures Contracts." In addition, the Company recorded a charge of $12 (net of
income tax benefits of $8) for the purchase of the interest rate option offset
by a gain on the portion of the interest rate option associated with the
issuance of Company-obligated mandatorily redeemable preferred securities of
subsidiary trust holding solely Company-guaranteed debentures ("Preferred
Securities"). The gain on the interest rate option associated with the Preferred
Securities was $6 (net of income tax expense of $4).
 
    In January 1999, AirTouch entered into an agreement to merge its operations
with a subsidiary of Vodafone Group Public Limited Company ("Vodafone"). See
Note 22--Subsequent Events--to the Consolidated Financial Statements.
 
    CABLE SYSTEMS.  In December 1998, the Company acquired Time Warner, Inc.'s
("Time Warner") cable systems in the cities of Dearborn and Wayne, Michigan for
$57. The systems serve approximately 31,000 subscribers. In addition, during
1998, MediaOne Group sold various cable television systems in California, Idaho,
Iowa and Washington, serving approximately 33,000 subscribers, for total
proceeds of $50.
 
    On October 13, 1998, MediaOne Group and Tele-Communications, Inc. ("TCI")
signed a definitive agreement to exchange certain of MediaOne Group's cable
television systems in Illinois and Michigan for certain of TCI's cable
television systems in South Florida and California. The cable systems each serve
approximately 500,000 subscribers. Consummation of the exchange is expected to
occur in mid-1999, subject to regulatory approvals. These cable systems had a
net book value of $521 at December 31, 1998,

NOTE 4: DOMESTIC ACQUISITIONS AND DISPOSITIONS (CONTINUED)
and contributed revenues of $253 and operating income of $33 during 1998. In
addition, MediaOne Group entered into a definitive agreement to sell its cable
television systems in Reno, Nevada for approximately $21. The Nevada systems
served approximately 10,000 subscribers, and closed in the first quarter of
1999. In accordance with SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," the Company
stopped depreciating and amortizing the systems held for sale.
 
    In May 1997, pursuant to a Federal Communications Commission ("FCC") order,
the Company entered into an agreement to sell its cable systems in Minnesota
(the "Minnesota System") for proceeds of $600. Under the terms of the agreement,
the Company had the right to terminate the agreement at any time upon payment of
a $30 termination fee. As a result of the Separation, the Company was no longer
prohibited by federal law from owning the Minnesota System. In February 1998, in
response to Old U S WEST's petition, the FCC granted a waiver which permitted
the Company to retain the Minnesota System. The Company terminated the agreement
to sell the Minnesota System and otherwise settled all claims related thereto.
 
    HIGH SPEED DATA JOINT VENTURE.  On June 15, 1998, MediaOne Group formed a
joint venture with Time Warner, TWE and Time Warner
Entertainment-Advance/Newhouse Partnership ("TWE/AN") called "ServiceCo, LLC"
(the "HSD Joint Venture") to deliver high speed data ("HSD") services. The
parties to the joint venture contributed certain of their respective HSD assets
into the HSD Joint Venture in exchange for common equity interests of
approximately 31.4 percent for MediaOne Group, 10.7 percent for Time Warner,
25.0 percent for TWE and 32.9 percent for TWE/AN. In addition, Microsoft
Corporation and Compaq Computer Corporation each contributed $212.5 million for
a respective 10 percent preferred equity investment in the HSD Joint Venture.
The preferred shares are convertible into a combined 20 percent common equity
interest in the HSD Joint Venture. MediaOne Group will provide HSD services
under the "Road Runner" brand name.
 
    Assuming the conversion of the preferred shares and taking into account
MediaOne Group's ownership in TWE, MediaOne Group would hold a proportionate
diluted common equity interest in the HSD Joint Venture of approximately 34.6
percent. MediaOne Group accounts for its investment in the HSD Joint Venture
under the equity method of accounting.
 
    The HSD Joint Venture is responsible for maintaining connections to the
Internet, providing technical customer support and developing national content.
The parties to the joint venture operate their respective HSD businesses and are
responsible for their respective customers' billing and customer service issues.
Accordingly, MediaOne Group continues to reflect HSD service revenues in its
consolidated results, as well as a service fee payable to the HSD Joint Venture
for services provided.
 
    COMPETITIVE LOCAL EXCHANGE BUSINESSES.  During November 1998, MediaOne Group
entered into a definitive agreement with Hyperion Communications to sell the
Company's investments in Continental Fiber Technologies, Inc. and Alternet of
Virginia, Inc., providers of business telephony services in Jacksonville,
Florida and Richmond, Virginia, respectively, for approximately $80, (the "CLEC
Businesses"). The sale is expected to close in the first half of 1999. In
accordance with SFAS No. 121, the Company has stopped depreciating these assets.
The CLEC Businesses had a net book value at December 31, 1998 of $33, and
contributed revenues of $14 and operating losses of $3 during 1998.

NOTE 4: DOMESTIC ACQUISITIONS AND DISPOSITIONS (CONTINUED)
 
    PRIMESTAR.  Prior to April 1, 1998, the Company held a 10.4 percent interest
in PrimeStar Partners, L.P. ("Old PrimeStar"). In addition, MediaOne distributed
PrimeStar direct broadcast satellite ("DBS") services to subscribers in its
service areas and, as a result, reflected consolidated operating results with
respect to such subscribers. On April 1, 1998, the Company contributed its
interest in Old PrimeStar, as well as its PrimeStar subscribers and certain
related assets, to PrimeStar, Inc. ("PrimeStar"), a newly formed entity, in
exchange for an approximate 10 percent interest in PrimeStar and $77 in cash
(the "PrimeStar Contribution").
 
    In December 1998, PrimeStar management provided a business plan to its board
of directors, of which MediaOne Group is a part. Additionally, in January 1999,
Hughes Electronics Corporation ("Hughes") entered into an agreement to purchase
PrimeStar's DBS assets. Based on its review of PrimeStar's business plan and on
the anticipated sale to Hughes, the Company believes it will not receive
proceeds on the sale of its investment in PrimeStar. As a result, MediaOne Group
recorded a charge of $163 ($100 after tax) to reduce the carrying amount of its
investment in PrimeStar to zero. MediaOne Group is currently a guarantor of
letters of credit for PrimeStar totaling approximately $100. See Note
22--Subsequent Events--to the Consolidated Financial Statements.
 
NOTE 5: OPERATING SEGMENTS
 
    In fourth-quarter 1998, the Company adopted SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." SFAS No. 131 establishes
standards for reporting information about operating segments in annual financial
statements and requires selected information about operating segments in interim
financial reports issued to stockholders. It also establishes standards for
disclosures about products and services and geographic areas. Operating segments
are components of an enterprise for which separate financial information is
available and which is evaluated regularly by the Company's chief operating
decision maker, or decision making group, in deciding how to allocate resources
and assess performance. Operating segments are managed separately and represent
strategic business units that offer different products and serve different
markets.
 
    The Company's reportable segments include: (1) domestic cable and broadband,
(2) international services, and (3) corporate and other. The domestic cable and
broadband segment is comprised of MediaOne and Multimedia Ventures. MediaOne
consists of cable television properties serving 5.0 million domestic subscribers
and passing 8.5 million domestic homes. Multimedia Ventures includes the
Company's equity interest in Time Warner Entertainment. The international
services segment includes the cable and broadband and wireless communications
operations located abroad, in addition to international corporate overhead.
Corporate and other includes the discontinued operations of New U S WEST,
capital assets (which was held for sale until December 31, 1998), investments in
domestic interactive services, the domestic wireless business (which was sold in
April 1998 in conjunction with the AirTouch Transaction), the international
directories operations (of which the wholly owned operations in the United
Kingdom and Poland were sold in 1997), and corporate overhead.
 
    MediaOne Group believes that proportionate financial data facilitates the
understanding and assessment of its results. Therefore, "Sales and Other
Revenues" for each segment is presented on a proportionate basis. Proportionate
results reflect the relative weight of MediaOne Group's ownership in each of its
respective domestic and international equity ventures together with the
consolidated results of its subsidiaries. In addition, the Company believes
earnings before interest, taxes, depreciation, amortization and other ("EBITDA")
is an important indicator of the operating performance of its businesses. As
such,

NOTE 5: OPERATING SEGMENTS (CONTINUED)
EBITDA is also presented, on a proportionate basis, for each segment. The
computation of EBITDA also excludes gains on asset sales, equity losses,
guaranteed minority interest expense, and restructuring charges. Adjustments
made to "Sales and Other Revenues" and EBITDA to arrive at proportionate results
are reversed in the column labeled "Eliminations and Adjustments," in
conformance with SFAS 131, so that in total, "Sales and Other Revenues" and
EBITDA reflect consolidated results. All other line items presented in the
tables reflect consolidated results.
 
    Consolidated results for the operating segments reflect the accounting
policies described in Note 3-- Summary of Significant Accounting Policies--to
the Consolidated Financial Statements. Intersegment sales and transfers are
accounted for at fair value as if the sales were to third parties. For
proportionate results, the venture's management determines its accounting
policies.
 
    Industry segment financial information follows. Certain prior year
information has been reclassified to conform with the 1998 presentation.

since the Acquisition date. Had the Acquisition occurred at the beginning of
1996, MediaOne Group's consolidated revenues would have been $3,543, loss from
continuing operations would have been $801, and basic loss per share of MediaOne
Group Stock would have been $1.37.
 
NOTE 6: INVESTMENT IN TIME WARNER ENTERTAINMENT
 
    On September 15, 1993, the Company acquired 25.51 percent pro-rata priority
capital and residual equity interests ("equity interests") in Time Warner
Entertainment for an aggregate purchase price of $2.553 billion. TWE owns and
operates substantially all of the entertainment assets previously owned by Time
Warner, consisting primarily of its filmed entertainment, programming-HBO and
cable television businesses.
 
    The Company has an option to increase its pro-rata priority capital and
residual equity interests in TWE from 25.51 percent up to 31.84 percent
depending upon cable operating performance. The option is exercisable, in whole
or in part, between January 1, 1999 and May 31, 2005, for an aggregate cash
exercise price ranging from $1.25 billion to $1.8 billion, depending upon the
year of exercise. Either TWE or the Company may elect that the exercise price
for the option be paid with partnership interests rather than cash.
 
    Pursuant to the TWE Partnership Agreement, there are four levels of capital.
From the most to least senior, the capital accounts are: senior preferred (held
by the general partners); A preferred priority capital (held pro rata by the
general and limited partners); B preferred priority capital (held by the general
partners); and residual equity capital (held pro rata by the general and limited
partners). Of the $2.553 billion contributed by the Company, $1.658 billion
represents a preferred priority capital and $895 represents residual equity
capital. The TWE Partnership Agreement provides for special allocations of
income and distributions of partnership capital. Partnership income, to the
extent earned, is allocated as follows: (1) to the partners so that the economic
burden of the income tax consequences of partnership operations is borne as
though the partnership was taxed as a corporation ("special tax allocations");
(2) to the partners' preferred capital accounts in order of priority described
above, at various rates of return ranging from 8 percent to 13.25 percent; and
(3) to the partners' residual equity capital accounts according to their
residual partnership interests. To the extent partnership income is insufficient
to satisfy all special allocations in a particular accounting period, the
unearned portion is carried over until satisfied out of future partnership
income. Partnership losses generally are allocated in reverse order, first to
eliminate prior allocations of partnership income, except senior preferred and
special tax income, next to reduce initial capital amounts, other than senior
preferred, then to reduce the senior preferred account and finally, to eliminate
special tax allocations.

(a) Represents the estimated fair value of net assets contributed as of
    formation of TWE, excluding partnership income or loss allocated thereto.
 
(b) Cumulative priority capital is not necessarily indicative of the fair value
    of the underlying priority capital interests.
 
(c) Net of $1,500 of cumulative cash distributions received by Time Warner.
 
(d) To the extent income allocations are concurrently distributed, the priority
    capital rates of return on the A preferred capital and the B preferred
    capital are 11% and 11.25%, respectively.
 
    Cash distributions are required to be made to the partners to permit them to
pay income taxes at statutory rates based on their allocable taxable income from
TWE ("Tax Distributions"). The aggregate amount of such Tax Distributions is
computed generally by reference to the taxes that TWE would have been required
to pay if it were a corporation. Tax Distributions are paid to the partners on a
current basis. For distributions other than those related to taxes or the senior
preferred, the TWE Partnership Agreement requires certain cash distribution
thresholds be met to the limited partners before the general partners receive
their full share of distributions. No cash distributions have been made to the
Company.
 
    Through the TWE management committee, the Company and Time Warner jointly
direct the businesses and affairs of TWE cable systems, subject in certain cases
to regulatory approval. The TWE management committee has full discretion and
final authority with respect to the businesses and affairs of such cable
systems. The TWE management committee consists of six voting members, of which
three members are designated by the Company and three members are designated by
Time Warner. Each voting member of the TWE management committee has one vote.
Any action required or permitted to be taken by the TWE management committee
must be approved by a majority of its members. Determinations of the TWE
management committee are binding upon TWE and the TWE board of representatives.
 
    The Company accounts for its investment in TWE under the equity method of
accounting. The excess of fair market value over the book value of total
partnership net assets implied by the Company's initial investment was $5.7
billion. This excess is being amortized on a straight-line basis over 25 years.
The Company's recorded share of TWE operating results represents allocated TWE
net income or loss adjusted for the amortization of the excess of fair market
value over the book value of the partnership net assets. As a result of this
amortization and the special income allocations described above, the Company's
recorded pretax share of TWE operating results before extraordinary item was $7,
$11 and $(4) in 1998, 1997 and 1996, respectively.

    As consideration for its expertise and participation in the cable operations
of TWE, the Company earned a management fee of $130 over five years, ending in
September 1998. The fee was payable over a four-year period beginning in 1995,
and final payment was received in September 1998. Management fees of $18, $26
and $26 were recorded to other income in 1998, 1997 and 1996. The Consolidated
Balance Sheets included a management fee receivable of $42 at December 31, 1997.
In addition, MediaOne purchases cable television programming from TWE and Time
Warner at market prices. These services totaled $142, $110 and $23 in 1998, 1997

had been jointly operated by the parties to provide telephony services to
business customers in their respective cable markets. TWE and TWE-A/N
distributed their ownership interest in TW Telecom on a pro rata basis to Time
Warner, MediaOne Group and Advance/Newhouse. As a result, MediaOne Group now
holds an 18.85 percent interest in TW Telecom. Since the investment in TW
Telecom resulted from a distribution by TWE, MediaOne Group's investment balance
in TWE was reduced in 1998 by $48, the book value of the TW Telecom investment
attributable to MediaOne Group. As of December 31, 1998, the investment in TW
Telecom is included in "Other Assets" in the Consolidated Balance Sheet. The
Company uses the cost method of accounting for its investment in TW Telecom.

provider in the United Kingdom, for approximately $1.1 billion in stock and
cash. Telewest raised cash for the acquisition through a rights offering to its
existing shareholders, including MediaOne Group. MediaOne Group purchased 85
million new Telewest shares at a cost of $131. In addition, MediaOne Group
recorded an estimated gain in equity of $39, net of deferred taxes of $25,
related to Telewest's acquisition of General Cable. On November 10, 1998,
MediaOne Group purchased an additional 175 million Telewest shares from
Southwestern Bell International Holdings at a price of $2.25 per share, or $394.
The Company now holds a 29.9 percent interest in Telewest. Telewest, which is
the only equity method investment of the Company for which a quoted market price
is available, had a market value of $1,803 and $464 at December 31, 1998 and
1997, respectively.
 
    In November 1998, MediaOne Group converted its note with Cable & Wireless
Optus Limited ("Optus") into 50 million Optus shares and entered into a put
option to lock in a floor price of Australian $1.44 per Optus share. The put
options expire during the first quarter of 1999. The Company also acquired 24.2
million Optus shares, related to MediaOne Group's anti-dilution rights, for $30.
Such shares were subsequently sold for $39, realizing an after tax gain on the
sale of $6. The Company accounts for its investment in Optus using the cost
method of accounting. At December 31, 1998, the investment is stated in the
Consolidated Balance Sheet at the investment's fair market value of $105. During
the first quarter of 1999, MediaOne Group sold its investment in the 50 million
Optus shares. See Note 22--Subsequent Events--to the Consolidated Financial
Statements.
 
    In July 1998, Westel 900, a digital wireless service company in Hungary,
repurchased shares of its stock. This repurchase resulted in an increase in
MediaOne Group's interest in Westel 900 to 49.0 percent from 46.6 percent.
 
    During the first quarter of 1997, the Company sold its five percent interest
in a French wireless venture for proceeds of $81. The Company recognized a gain
of $31, net of income tax expenses of $20. On October 27, 1997, the Company sold
its 90 percent interest in Fintelco, S.A. ("Fintelco"), a cable and
telecommunications venture located in Argentina, for proceeds of $641. The
Company acquired a 50 percent interest in Fintelco in connection with the
Continental Acquisition and then acquired an additional 40 percent interest in
August 1997, to bring its total interest in Fintelco to 90 percent. The Company
recognized a gain on the sale of $80, net of income tax expenses of $55.

    At December 31, 1998 and 1997, the difference between the carrying amount
and the Company's interest in the underlying equity of the international
ventures was approximately $160 and $23, respectively. The increase during 1998
was due primarily to a purchase premium of $136 related to Telewest shares
acquired during the year, which is being amortized over 20 years. The remaining
difference has been allocated primarily to licenses and is being amortized over
lives ranging from 5 to 20 years.
 
    FOREIGN CURRENCY TRANSACTIONS.  The Company selectively enters into forward
and purchased option contracts to manage the market risks associated with
fluctuations in foreign exchange rates after considering offsetting foreign
exposures among international operations. The use of forward and purchased
option contracts allows the Company to fix or cap the cost of firm foreign
investment commitments, the amount of foreign currency proceeds from sales of
foreign investments, the repayment of foreign currency denominated receivables
and the repatriation of dividends. All foreign exchange contracts have
maturities of one year or less. The use of such contracts was limited in 1998
and 1997. As of December 31, 1998, there were no foreign exchange contracts
outstanding. As of December 31, 1997, the market value of foreign exchange
contracts outstanding was not material.
 
    Forward contracts were selectively used to hedge foreign denominated
proceeds from the sale of foreign investments and foreign denominated
receivables during 1998 and 1997. Foreign currency pretax hedging gains of $1
and $5 were included in earnings in the years ended December 31, 1998 and 1997,

respectively. The counterparties to these contracts are major financial
institutions. The Company is exposed to credit loss in the event of
nonperformance by these counterparties. The Company does not have significant
exposure to an individual counterparty and does not anticipate nonperformance by
any counterparty.
 
    Foreign currency transaction pretax gains of $13 and pretax losses of $40
were included in earnings in the years ended December 31, 1998 and 1997,
respectively.
 
    EVALUATION OF ASIAN INVESTMENTS.  During 1997, the value of the Malaysian
currency declined 36 percent and the Indonesian currency declined 57 percent as
compared with the U. S. dollar. As a result of this significant decline, the
Company reviewed its investments in Malaysia and Indonesia and concluded that
each investment was impaired and in each case the fair value of the investment
was zero as of December 31, 1997. The Company recorded pretax charges of $145
and $55 in 1997 related to the ventures in Malaysia and Indonesia, respectively.
 
    In the case of Malaysia, the charge of $145 in 1997 was to recognize that
the investment was impaired and to write down the carrying value of the
investment to its fair value of zero. The following factors were considered by
management in determining that the investment was impaired:
 
    - The venture had negative cash flow and no ability to meet its debt
      obligations of $482 due in 1998.
 
    - As determined on a U. S. GAAP basis, the venture's liabilities exceeded
      its assets as of December 31, 1997, making the venture insolvent at that
      time.
 
    - The business plan for the venture contemplated a significant contribution
      to cash flows from the wireline business. The actual and potential cash
      flows of the venture have been severely diminished by the inability of the
      venture to effectively establish the wireline business.
 
    During 1998, British Telecom acquired a 33.3 percent stake in Binariang SDN
BHD, the investment in Malaysia, and assumed MediaOne Group's loan guarantee of
the venture. As a result, the Company's interest in the venture was diluted to
12.6 percent from 19 percent, and the Company considers its investment to be a
cost method investment. MediaOne Group continues to evaluate opportunities to
exit this venture.
 
    In the case of Indonesia, the net book value of the venture had been reduced
to its fair value of zero through recognition of $43 of equity losses during
1997. The $55 charge in 1997 was to recognize probable funding commitments in
connection with a shareholder support agreement. The probable funding
commitments consisted of the Company's remaining contractual commitment under
the shareholder support agreement of $19 and its partners' remaining commitments
of $36, as of December 31, 1997. Under the terms of the shareholder support
agreement, each shareholder is responsible for the full unfunded liability if
the other shareholders do not meet their proportionate obligations. As a result,
the Company has accrued for its partners' share of the commitment under the
shareholder support agreement. During 1998, MediaOne Group funded $6 under the
shareholder support agreement and the partners funded $10. The Company is
currently attempting to restructure its investment in Indonesia.

NOTE 7: NET INVESTMENT IN INTERNATIONAL VENTURES (CONTINUED)
    The following factors were considered by management in 1997 in determining
that the Indonesian investment was impaired and that accrual of the Company's
and its partners' funding liabilities were necessary:
 
    - As determined on a U. S. GAAP basis, the venture's liabilities,
      predominantly U. S. dollar denominated debt, exceeded its assets as of
      December 31, 1997.
 
    - Management believed the venture was not viable given the political and
      economic uncertainties in Indonesia.
 
    - The venture had ceased funding capital projects.
 
    The Company's other ventures in Asia, located in Japan, Singapore and India,
were evaluated for impairment at December 31, 1997. Such evaluation indicated
there was no impairment as the fair value of these ventures exceeded their
recorded values.

NOTE 10: DEBT
 
    On June 12, 1998, $4.9 billion notional medium and long-term debt was
redeemed as part of the Refinancing for a total cash redemption amount of $5.5
billion. MediaOne Group extinguished the debt by issuing commercial paper at a
weighted-average interest rate of 5.85 percent. In accordance with the
Separation Agreement, New U S WEST funded to MediaOne Group $3.9 billion related
to the Dex Alignment. The Company used the funds to repay a portion of the
amount of commercial paper issued in connection with the Refinancing. Debt
extinguishment costs related to the Refinancing totaled $333 (net of income tax
benefits of $209) and are reflected in the Consolidated Statements of Operations
as an extraordinary item. In addition to refinancing costs, such costs included
the difference between the market and face value of the debt redeemed and a
charge for unamortized debt issuance costs. MediaOne Group financed the debt
extinguishment costs by issuing commercial paper, net of a $140 reimbursement by
New U S WEST for shared costs.
 
    Remaining commercial paper issued in connection with the Refinancing was
subsequently repaid with proceeds generated from the Exchangeable Notes
offering, as described below in "Long-term Debt."
 
    In connection with the AirTouch Transaction, AirTouch assumed $1,350 of
short-term debt from MediaOne Group.

    The weighted-average interest rate on commercial paper was 6.09 percent and
6.15 percent at December 31, 1998 and 1997, respectively. In May 1998, MediaOne
Group entered into 365-day and 5-year bank credit facilities totaling $4.0
billion to support its commercial paper program. The facilities were reduced
effective December 1998 to a total of $3.0 billion. At December 31, 1998, $2.8
billion was available on the facilities.
 
    The bank loan at December 31, 1997 was a floating-rate loan denominated in
Czech Koruna. In January 1997, the Company paid the cash portion of the
Continental Acquisition consideration totaling $1,150. This payment was financed
with commercial paper.
 
    On December 15, 1998, $130 of Debt Exchangeable for Common Stock ("DECS")
matured. Effective with the Separation, the DECS became the obligation of
MediaOne Group. In accordance with the terms of the original debt issuance, the
DECS were redeemed for shares of Enhance Financial Services Group, Inc.
("Enhance") held by MediaOne Group. In addition, the Company settled an option
issued in 1997 for the purchase of MediaOne Group's residual shares of Enhance
common stock at the DECS

maturity, resulting in a pretax gain of $9. As a result of both transactions,
the Company has disposed of its ownership in shares of Enhance.
 
    On May 13, 1996, Old U S WEST issued $254 of DECS due May 15, 1999, in the
principal amount of $26.63 per note. The notes bear annual interest at 7.625
percent. Effective with the Separation, the DECS became the obligation of
MediaOne Group. Upon maturity, the DECS will be mandatorily redeemed by the
Company for shares of Financial Security Assurance Holdings Ltd. ("FSA") held by
MediaOne Group or the cash equivalent, at MediaOne Group's option. The number of
shares to be delivered at maturity varies based on the per share market price of
FSA. If the market price is $26.63 per share or less, one share of FSA will be
delivered for each note; if the market price is between $26.63 and $32.48 per
share, a fractional share is delivered so that the value at maturity is equal to
$26.63; if the market price is greater than $32.48 per share, .8197 of a share
is delivered for each note. At December 31, 1998, the FSA shares had a market
price of $54.25 per share.
 
LONG-TERM DEBT
 
    In August and September 1998, MediaOne Group issued 29 million shares of
6.25 percent Exchangeable Notes (the "Exchangeable Notes") for an issuance price
of $58.125 per note, or gross proceeds of $1,686. The notes mature on August 15,
2001 and are mandatorily redeemable at MediaOne Group's option into (i) shares
of AirTouch common stock held by MediaOne Group, (ii) the cash equivalent, or
(iii) a combination of cash and AirTouch common stock. The number of shares of
AirTouch common stock to be exchanged at maturity for each Exchangeable Note,
and/or the cash equivalent, varies based upon the fair value of the AirTouch
common stock, as follows:
 
    (a) If the fair value of AirTouch common stock is greater than or equal to
       $71.75 per share, each Exchangeable Note is equivalent to .8101 of a
       share of AirTouch common stock;
 
    (b) If the fair value of AirTouch common stock is less than or equal to
       $58.125 per share, each Exchangeable Note is equivalent to one share of
       AirTouch common stock; or
 
    (c) If the fair value of AirTouch common stock is less than $71.75 per share
       but greater than $58.125 per share, each Exchangeable Note is equivalent
       to a fractional share of AirTouch common stock equal to the percent of
       the initial issuance price per Exchangeable Note versus the fair value of
       the AirTouch common stock per share.
 
    The Exchangeable Notes are unsecured obligations of MediaOne Group, ranking
equally in right of payment with all other unsecured and unsubordinated
obligations of MediaOne Group. MediaOne Group used the proceeds from the debt
issuance to reduce outstanding commercial paper and for general corporate
purposes.
 
    The Exchangeable Notes are being accounted for as an indexed debt instrument
since the maturity value of the Exchangeable Notes is dependent upon the fair
value of the underlying AirTouch common stock. The Company has, therefore,
eliminated the market risk on a decline in the AirTouch common stock value below
$58.125 per share on 29 million of the 59.3 million shares held by the Company.
The maturity value of the Exchangeable Notes was increased by $16 from its
original issuance value to reflect the corresponding increase in the fair value
of the underlying AirTouch common stock at December 31, 1998. At December 31,
1998, the AirTouch common stock had a fair value of $72.4375 per share; MediaOne
Group would be entitled to 19 percent of the fair value in excess of $71.75 per
share on 29 million shares of AirTouch common stock. Since the AirTouch common
stock is a cost method investment being accounted

for as "available for sale" securities under SFAS No. 115, "Accounting for
Certain Investments in Debt and Equity Securities," changes in the maturity
value of the Exchangeable Notes are being recorded in equity as unrealized gains
or losses. See Note 22--Subsequent Events--to the Consolidated Financial
Statements for a discussion of the potential merger of AirTouch with Vodafone.
 
    In conjunction with the Refinancing, MediaOne Group assumed from Old U S
WEST $351 of medium and long-term debt securities which remained outstanding
after the Refinancing. The debt securities were already reflected in the
outstanding debt balances of MediaOne Group's restated Consolidated Balance
Sheet as of December 31, 1997.
 
    Since the capital assets segment is no longer being accounted for as assets
held for sale as of the end of 1998, its debt balances are now reflected in the
Company's consolidated debt balances. As such, long-term debt of the Company
increased $155 and short-term debt increased $43 at December 31, 1998, related
to debt balances of the capital assets segment. See Note 23--Net Investment in
Assets Held for Sale--to the Consolidated Financial Statements. The long-term
debt increase primarily represents non recourse loans issued in September 1997
by MediaOne Financial Services, Inc. ("Financial Services"), a subsidiary of the
Company and a member of the capital assets segment, which are securitized by
certain finance receivables of Financial Services. The loans bear interest at an
average rate of 6.9 percent and mature in April, 2009.
 
    In January 1997, the Company issued medium- and long-term debt totaling $4.1
billion, at a weighted-average interest rate of 7.47 percent, related to the
refinancing of outstanding commercial paper issued in conjunction with the
refinancing of $3,657 of the debt assumed from Continental in the Continental
Acquisition. As discussed above, the majority of such debt was extinguished in
1998 as a result of the Separation and the Refinancing.

INTEREST RATE RISK MANAGEMENT
 
    The objective of an interest rate risk management program is to minimize the
total cost of debt over time and the interest rate variability. This is achieved
through the use of interest rate swaps, which adjust the ratio of fixed- to
variable-rate debt. Under an interest rate swap, the Company agrees with another
party to exchange interest payments at specified intervals over a defined term.
Interest payments are calculated by reference to the notional amount based on
the fixed- and variable-rate terms of the swap agreements. MediaOne Group had no
swaps or interest rate contracts outstanding as of December 31, 1998.
 
    During fourth-quarter 1996, the Company purchased $1.5 billion notional of
put options on U. S. Treasury Bonds to protect against an increase in interest
rates in conjunction with the 1997 refinancing of debt assumed from Continental
in connection with the Continental Acquisition. The contracts closed in January
1997 and a deferred gain of $5 was recognized. The gain was recognized in 1998
in conjunction with the Refinancing as part of the loss on debt extinguishment.

discounting future cash flows. The carrying value of foreign exchange contracts
approximate the fair values based on estimated amounts the Company would receive
or pay to terminate such agreements. It is not practicable to estimate the fair
value of financial guarantees because there are no quoted market prices for
similar transactions.
 
    The fair values of interest rate swaps are based on estimated amounts the
Company would receive or pay to terminate such agreements taking into account
current interest rates and creditworthiness of the counterparties.
 
    The fair values of long-term debt, including debt associated with the
capital assets segment, and Preferred Securities and Minority interest in
Centaur Funding, are based on quoted market prices where available or, if not
available, are based on discounting future cash flows using current interest
rates.

NOTE 13: MINORITY INTEREST IN CENTAUR FUNDING
 
    On December 15, 1998, Centaur Funding Corporation ("Centaur"), a special
purpose entity consolidated by MediaOne Group, issued three series of preferred
shares to external investors (the "Preference Shares") as well as $25 of common
securities. The Company owns all of the outstanding common securities,
representing a 9.9 percent voting interest in Centaur. Centaur was formed for
the principal purpose of raising capital through the issuance of the Preference
Shares. The net proceeds from the issuance of the Preference Shares were loaned
to MediaOne SPCII, LLC ("MediaOne SPCII"), a subsidiary of MediaOne Group (the
"MediaOne SPC II Notes"). Principal and interest payments on the MediaOne SPC II
Notes are expected to be Centaur's principal source of funds to make dividend
and redemption payments on the Preference Shares. In addition, the dividend
payments and certain redemption payments on the Preference Shares will be
determined by reference to the dividend and redemption activity of the 5.143
percent Class D Cumulative Preferred Shares, Series 1998 of AirTouch (the "Class
D ATI Shares") and the 5.143 percent Class E Cumulative Preferred Shares, Series
1998 of AirTouch (the "Class E ATI Shares" and collectively with the Class D ATI
Shares, the "AirTouch Preferred Shares"). The AirTouch Preferred Shares are
owned by MediaOne SPCII. Payments on the Preference Shares are neither
guaranteed nor secured by MediaOne Group. The sole assets of Centaur are the

and the proceeds from the sale of the common securities, which may be invested
in certain eligible investments as outlined in Centaur's articles of
incorporation.
 
    The AirTouch Preferred Shares, 75 percent of the outstanding common stock of
MediaOne International Holdings, Inc., (the "International Stock"), and a
certain intercompany note receivable from MediaOne of Colorado, a wholly owned
subsidiary of the Company, to MediaOne SPCII and certain other assets are
properties of MediaOne SPCII and are not available to pay creditors of any
member of the Company, other than creditors of MediaOne SPCII. The International
Stock owned by MediaOne SPCII may be transferred or dividended by MediaOne SPCII
to another member of the MediaOne Group if such transfer or dividend is in
compliance with certain covenants and limitations. MediaOne SPCII is a limited
liability company, the membership interest of which is owned by MediaOne SPCI
LLC ("MediaOne SPCI"), a wholly owned subsidiary of the Company. That membership
interest is the property of MediaOne SPCI and is not available to pay creditors
of any member of MediaOne Group, other than creditors of MediaOne SPCI.

(1) Maturity dates of the Series B and Series C Preference Shares are referenced
    to the AirTouch Preferred Shares.
 
    The Auction Market Preference Shares, Series A (the "Series A Preference
Shares") have a liquidation value of two hundred and fifty thousand dollars per
share, and were recorded at their liquidation value less issuance costs of $3.
Dividends on the Series A Preference Shares are payable quarterly as and when
declared by Centaur's Board of Directors out of funds legally available.
 
    The 9.08 percent Cumulative Preference Shares, Series B (the "Series B
Preference Shares") have a liquidation value of one thousand dollars per share,
and were recorded at their liquidation value less issuance costs of $25.
Dividends on the Series B Preference Shares are payable quarterly in arrears
when declared by Centaur's Board of Directors out of funds legally available. In
addition, dividends may be declared and paid only to the extent that dividends
have been declared and paid on the AirTouch Preferred Shares.
 
    The Preference Shares, Series C (the "Series C Preference Shares") have a
liquidation value of one thousand dollars per share at maturity, and were
recorded at their fair value less issuance costs of $3. The value of the Series
C Preference Shares will be accreted to reach its liquidation value upon
maturity.
 
    Certain redemption payments on the Series B and Series C Preference Shares
will be determined by reference to the redemption of the AirTouch Preferred
Shares. On April 7, 2018, all of the outstanding shares of the Class E ATI
Shares must be redeemed. The Class E ATI Shares represent 50 percent of the

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 13: MINORITY INTEREST IN CENTAUR FUNDING (CONTINUED)
AirTouch Preferred Shares. Consequently, if AirTouch redeems all of the Class E
ATI Shares, Centaur must redeem 50 percent of the outstanding Series B and
Series C Preference Shares. In addition, AirTouch has the option on or after
April 7, 2018, to redeem the Class D ATI Shares. If AirTouch redeems all or a
portion of the Class D ATI Shares, then Centaur would be obligated to redeem the
same percentage of the Series B and Series C Preference Shares. Any remaining
Series B and Series C Preference Shares would be redeemed upon maturity on April
21, 2020, to the extent that AirTouch has redeemed the remaining Class D ATI
Shares.
 
    The Series A, Series B and Series C Preference Shares are recorded as
"Minority Interest in Centaur Funding" on the Consolidated Balance Sheets of the
Company. The Series B Preference Shares rank equally with the Series C
Preference Shares as to redemption payments and upon liquidation, and the Series
B and Series C Preference Shares rank senior to the Series A Preference Shares
and the common shares of Centaur as to redemption payments and upon liquidation.
 
    The Series B Preference Shares rank senior to the Series A Preference Shares
and the common shares with respect to dividend payments. Centaur may only pay a
dividend to its common shareholder when its assets, including the MediaOne SPC
II Notes, exceed the liquidation preference and accumulated and unpaid dividends
on the Series B and Series C Preference Shares by $28 after paying the common
dividends, and when it has a cash balance, including qualified investments, in
excess of $28 after paying the common dividend.
 
    At December 31, 1998, Centaur held $26 in cash for its exclusive use. Since
Centaur's cash management options are limited to non-affiliated, risk-free
investments, and it is restricted from loaning the $26 in cash to MediaOne Group
and its subsidiaries, Centaur's cash balance is not included in the Company's
cash and cash equivalents balance. Instead, Centaur's cash balance has been
classified in the Consolidated Balance Sheets of the Company as part of "Other
Assets."

THE EXCHANGE OFFER
 
    On June 12, 1998, MediaOne Group tendered for cash or exchange all of the
outstanding Preferred Securities (the "Exchange Offer"). At that time, the
Company had outstanding $600 face value of 7.96 percent Preferred Securities of
Old U S WEST Financing I ("Financing I"), a subsidiary of Old U S WEST, and $480
face value of 8.25 percent Preferred Securities of Old U S WEST Financing II
("Financing II"), a subsidiary of Old U S WEST. Of the total outstanding, $301
face value of 7.96 percent Preferred Securities and $237 face value of 8.25
percent Preferred Securities were redeemed for cash. The cash redemption amount
of $570 was financed by issuing commercial paper at a weighted average interest
rate of 5.85 percent, which was subsequently repaid with net proceeds from the
Exchangeable Notes issuance. See Note 10--Debt--to the Consolidated Financial
Statements.
 
    In addition, $266 face value of 7.96 percent Preferred Securities of
Financing I were exchanged for $274 fair value of 9.30 percent Preferred
Securities issued by MediaOne Finance Trust I ("Finance I"), a subsidiary of
MediaOne Group, and $213 face value of 8.25 percent Preferred Securities of
Financing II were exchanged for $224 fair value of 9.50 percent Preferred
Securities issued by MediaOne Finance Trust II ("Finance II"), a subsidiary of
MediaOne Group. The Preferred Securities of Finance I and Finance II were
recorded as issued at fair value of $25.75 and $26.30 per security,
respectively. Finance I and Finance II also issued $9 and $7, respectively, of
common securities which are held by MediaOne Group. With the exception of the
dividend rates, the terms and maturity of the Finance I and Finance II Preferred
Securities are substantially the same as those of the Financing I and Financing
II Preferred Securities, respectively.
 
    The Preferred Securities of Financing I and Financing II which were neither
redeemed for cash nor exchanged for new Preferred Securities remain outstanding
and their respective common securities were retained by MediaOne Group.
 
    As a result of the Exchange Offer, MediaOne Group recorded a charge to
equity of $53, after tax benefits of $28. Such charge represented redemption
costs, including the difference between the face and

market value of the securities, and a charge for unamortized issuance costs.
Also included was a charge of $19 related to market value premiums on the
exchanged securities.
 
    On October 23, 1998, MediaOne Finance Trust III ("Finance III"), a
subsidiary of MediaOne Group, issued $500 of 9.04 percent Preferred Securities
and $15 of common securities. The common securities are held by MediaOne Group.
 
    Total proceeds from the issuance of the Preferred Securities and the common
securities of Financing I and Financing II (the "Old Trusts"), and Finance I,
Finance II and Finance III, (the "New Trusts", and collectively with the Old
Trusts, "the Trusts"), were used to purchase Subordinated Deferrable Interest
Notes (the "Subordinated Debt Securities") from MediaOne Group Funding, Inc.
("MediaOne Funding"), a wholly owned subsidiary of MediaOne Group, the
obligations under which are fully and unconditionally guaranteed by MediaOne
Group (the "Debt Guarantees"). The Subordinated Debt Securities have the same
interest rate and maturity date as the Preferred Securities to which they
relate. The sole assets of the Trusts are and will be the Subordinated Debt
Securities and the Debt Guarantees. In the Exchange Offer, the Subordinated Debt
Securities that relate to the remaining outstanding Preferred Securities of the
Old Trusts were assumed by MediaOne Group and the related Debt Guarantees were
extinguished.
 
    MediaOne Group has guaranteed the payment of interest and redemption amounts
to holders of the Preferred Securities when the Trusts have funds available for
such payments (the "Payment Guarantee") as well as the Company's and MediaOne
Funding's undertaking to pay all of the costs, expenses and other obligations
(the "Expense Undertaking") of the Old Trusts and the New Trusts, respectively.
The Payment Guarantee and the Expense Undertaking, including MediaOne Group's
guarantee with respect thereto, considered together with MediaOne Funding's
obligations under the indenture and Subordinated Debt Securities and MediaOne
Group's obligations under the indenture, declaration and Debt Guarantees,
constitute a full and unconditional guarantee by MediaOne Group of the Trusts'
obligations under the Preferred Securities. The interest and other payment dates
on the Subordinated Debt Securities are the same as the distribution and other
payment dates on the Preferred Securities. Under certain circumstances, the
Subordinated Debt Securities may be distributed to the holders of Preferred
Securities and common securities in liquidation of the Trusts.
 
    All of the Subordinated Debt Securities are redeemable by the Company or
MediaOne Funding at a redemption price of $25.00 per security, plus accrued and
unpaid interest. If the Company or MediaOne Funding redeems the Subordinated
Debt Securities, the Trusts are required to concurrently redeem their respective
Preferred Securities at $25.00 per share plus accrued and unpaid distributions.
The 9.30 percent and the 7.96 percent Subordinated Debt Securities are
redeemable in whole or in part at any time on or after September 11, 2000. The
9.50 percent and the 8.25 percent Subordinated Debt Securities are redeemable in
whole or in part at any time on or after October 29, 2001. The 9.04 percent
Subordinated Debt Securities are redeemable in whole or in part at any time on
or after October 28, 2003.

NOTE 15: PREFERRED STOCK SUBJECT TO MANDATORY REDEMPTION (CONTINUED)
Stock was recorded at fair value of $50.00 per share at June 30, 1997, which was
equal to its liquidation value. Upon redemption, the preferred stockholders may
elect to receive cash or convert their Series E Preferred Stock into MediaOne
Group Stock. Cash redemption is equal to the Series E Preferred Stock's
liquidation value of $50.00 per share, plus accrued dividends. The number of
shares of MediaOne Group Stock to be received upon conversion is $47.50 per
share divided by the then current market price of MediaOne Group Stock. The
conversion rate is subject to adjustment by the Company under certain
circumstances.
 
    The Series E Preferred Stock is redeemable as follows: (a) the Company may
call for redemption all or any part of the Series E Preferred Stock beginning on
June 30, 2002; (b) on a yearly basis beginning August 1, 2007, and continuing
through August 1, 2016, the Company will redeem 49,704 shares of Series E
Preferred Stock, and on June 30, 2017, all of the remaining outstanding shares
of Series E Preferred Stock; or (c) all of the outstanding Series E Preferred
Stock shall be redeemed upon the occurrence of certain events, including the
dissolution or sale of all or substantially all of MediaOne Group.
 
    On September 2, 1994, Old U S WEST issued to Fund American Enterprises
Holdings Inc. ("FFC") 50,000 shares of a class of 7 percent Series C Cumulative
Redeemable Preferred Stock (the "Series C Preferred Stock") for a total of $50.
See Note 23--Net Investment in Assets Held for Sale--to the Consolidated
Financial Statements. Effective with the Separation, the Series C Preferred
Stock remains outstanding and represents shares of Series C Preferred Stock of
MediaOne Group. The Series C Preferred Stock was recorded at the fair market
value of $51 at the issue date. The Company has the right commencing September
2, 1999, to redeem the shares for one thousand dollars per share plus unpaid
dividends and a redemption premium. The shares are mandatorily redeemable in
2004 at face value plus unpaid dividends. At the option of FFC, the preferred
stock also can be redeemed for common shares of FSA. The market value of the
option was $79 and $71 (based on the Black-Scholes model) at December 31, 1998
and 1997, respectively, with no carrying value.
 
    The Series E and Series C Preferred Stocks rank senior to all classes of
MediaOne Group's common stock, are subordinated to any senior debt and the
Preferred Securities, and rank equally with the Series D Preferred Stock. See
Note 16--Shareowners' Equity--to the Consolidated Financial Statements.
 
NOTE 16: SHAREOWNERS' EQUITY
 
    Prior to the Separation, Old U S WEST had outstanding two separate classes
of common stock. Upon Separation, and in accordance with the terms of the
Separation Agreement, each outstanding share of Media Stock remains outstanding
and represents one share of MediaOne Group Stock. Each share of Media Stock held
as treasury stock by Old U S WEST now represents one share of MediaOne Group
Stock held as treasury stock by MediaOne Group. All issued and outstanding
shares of Communications Stock were redeemed for shares of New U S WEST common
stock. In addition, since the distribution of New U S WEST was accounted for at
fair value, retained earnings were reduced by $24,924 and common stock was
reduced by $421, representing the fair value of the businesses comprising New U
S WEST previously held by Old U S WEST.
 
    COMMON STOCK.  For 1998, other activity includes $44 for tax benefits on
stock option exercises, a $39 gain related to the acquisition of General Cable
by Telewest, a $39 gain on the exercise of a call option on shares of the
Company's stock, and miscellaneous activity of $25. In connection with the

    SERIES D PREFERRED STOCK.  On November 15, 1996, Old U S WEST issued
19,999,478 shares of 4.5 percent, 20 year, Series D Preferred Stock (the "Series
D Preferred Stock") to Continental shareowners as partial consideration for the

D Preferred Stock as and when declared by the Board of Directors of MediaOne
Group (the "Board of Directors") out of funds legally available. Effective with
the Separation, the Series D Preferred Stock remains outstanding and represents
Series D Preferred Stock of MediaOne Group. The Series D Preferred Stock has a
liquidation value of $50 per share and was recorded at the November 15, 1996
fair value of $46 per share. The Series D Preferred Stock is convertible at any

NOTE 16: SHAREOWNERS' EQUITY (CONTINUED)
holders of the Series D Preferred Stock did not participate in the Dex Dividend
upon Separation, the Board of Directors adjusted the conversion rate of the
Series D Preferred Stock from 1.905 shares of MediaOne Group Common Stock per
share of Series D Preferred Stock to 1.98052 per share. Between November 15,
1999 and November 15, 2001, the Series D Preferred Stock is redeemable at par,
at the option of the Company, into shares of MediaOne Group Stock if the market
price of MediaOne Group common shares has closed at or above $34.08 per share
for at least 20 of the 30 consecutive trading days prior to the notice of
redemption. After November 15, 2001, the Series D Preferred Stock is redeemable
at par, at the option of the Company, in cash, MediaOne Group Stock, or any
combination of cash and stock. If MediaOne Group Stock is elected, the number of
shares to be issued will be determined based on the average market price for the
ten consecutive trading days ending on the third business day prior to
redemption, reduced by five percent. On November 15, 2016, the Company is
required to redeem the Series D Preferred Stock, at its election, for cash,
MediaOne Group Stock, or any combination of cash and stock. Upon certain events,
including the disposition of all or substantially all of the properties and
assets attributed to MediaOne Group, the Series D Preferred Stock becomes
mandatorily redeemable. The Series D Preferred Stock ranks senior to all classes
of MediaOne Group common stock, is subordinated to any senior debt and the
Preferred Securities, and ranks equally with the Series E and C Preferred
Stocks.
 
    LEVERAGED EMPLOYEE STOCK OWNERSHIP PLAN ("LESOP").  MediaOne Group sponsors
a defined contribution savings plan for substantially all employees of MediaOne
Group, except for foreign national employees. Effective in 1997, employees of
the Atlanta cable systems also became eligible to participate in the defined
contribution savings plan. Borrowings associated with the LESOP were repaid in
May 1998. Prior to that time, the borrowings associated with the LESOP, which
were unconditionally guaranteed by Old U S WEST, were included in the
Consolidated Balance Sheets of the Company and corresponding amounts were
recorded as reductions to shareowners' equity. Contributions from Old U S WEST
as well as dividends on unallocated shares held by the LESOP ($1, $3 and $5 in
1998, 1997 and 1996, respectively) were used for debt service.
 
    The Company matched a percentage of eligible employee contributions with
shares of MediaOne Group Stock. Shares in the LESOP were released as principal
and interest were paid on the debt. At December 31, 1998, 12,831,958 shares of
MediaOne Group Stock and 12,537,710 shares of Communications Stock had been
allocated from the LESOP to participants' accounts. At December 31, 1998, there
are no remaining MediaOne Group shares to be allocated.
 
    The Company recognizes expense based on the cash payments method. MediaOne
Group's contributions to the plan (excluding dividends) were $8, $9 and $10 in
1998, 1997 and 1996, respectively, of which $1, $1 and $2, respectively, have
been classified as interest expense.
 
    SHAREHOLDER RIGHTS PLAN.  The Board of Directors has adopted a shareholder
rights plan which, in the event of a takeover attempt, would entitle existing
shareowners to certain preferential rights. The rights expire on April 6, 1999,
and are redeemable by MediaOne Group at any time prior to the date they would
become effective. The expiration date for the rights has been extended to the
year 2009. See Note 22-- Subsequent Events--to the Consolidated Financial
Statements.
 
    COMPREHENSIVE INCOME.  During 1998, MediaOne Group adopted the provisions of
SFAS No. 130, "Reporting Comprehensive Income." SFAS No. 130 establishes
standards for reporting comprehensive income and its components within the
financial statements. Comprehensive income includes net income

NOTE 16: SHAREOWNERS' EQUITY (CONTINUED)
and other changes to equity not included in net income, such as foreign currency
translation and unrealized gains or losses on debt and equity securities.
 
    Of the total net unrealized gains on debt and equity securities during 1998,
$826 (net of deferred taxes of $530), relates to the Company's investment in
AirTouch common and preferred stock acquired in connection with the AirTouch
Transaction. During 1998, MediaOne Group recorded an unrealized gain of $147
related to its investment in AirTouch preferred stock. This unrealized gain was
fully offset by a loss on an interest rate swap agreement which was designed to
minimize the Company's exposure to fluctuations in the fair value of the
AirTouch preferred stock as a result of interest rate changes.
 
    The following table presents the components of other comprehensive income
and their related tax impacts. It also presents reclassification adjustments
related to gains realized on the sale of debt and equity securities.

NOTE 17: EARNINGS PER SHARE
 
    The following table reflects the computation of basic and diluted earnings
(loss) per share for MediaOne Group Stock and Communications Stock, in
accordance with the provisions of SFAS No. 128, "Earnings Per Share." The
dilutive securities for 1998 represent the incremental weighted average shares
from potential share issuances associated with stock options for MediaOne Group
Stock and Communications Stock, and the assumed conversion of the convertible
Series D Preferred Stock for MediaOne Group Stock. The diluted earnings (loss)
and related per share amounts for 1997 and 1996 do not include potential share
issuances associated with stock options and the convertible Series D Preferred
Stock since the effect would have been antidilutive on the loss from continuing
operations.

NOTE 18: STOCK INCENTIVE PLANS
 
    MediaOne Group maintains stock incentive plans for executives and other
employees and nonemployees, primarily members of the Board of Directors. The
Amended MediaOne Group 1994 Stock Plan (the "Plan") is a successor plan to the
Amended 1994 Stock Plan which was maintained by Old U S WEST. Under the Amended
1994 Stock Plan, each outstanding Old U S WEST stock option was converted into
one Media Group and one Communications Group stock option. Subsequently, each
group granted options primarily in its own stock. Effective on the Separation,
stock options, whether held by individuals who became MediaOne Group or New U S
WEST employees, continued to be outstanding as stock options for MediaOne Group
and New U S WEST. The number of MediaOne Group stock options and the exercise
prices were adjusted to preserve the economic value of the options before and
after the Dex Dividend. The Plan is administered by the Human Resources
Committee of the Board of Directors with respect to officers, executive officers
and outside directors and by a special committee with respect to all other
eligible employees and eligible nonemployees.
 
    As of December 31, 1998, the maximum aggregate number of shares of MediaOne
Group Stock that could have been granted in any calendar year for all purposes
under the Plan was three-quarters of one percent (0.75 percent) of the shares
outstanding (excluding shares held in treasury) on the first day of such
calendar year. In the event that fewer than the full aggregate number of shares

shares not issued may be added to the shares available for issuance in any
subsequent year or years. Options granted vest over periods up to three years
and may be exercised no later than 10 years after the grant date.
 
    The compensation cost that has been included in income in accordance with
APB Opinion No. 25, "Accounting for Stock Issued to Employees," was $26, zero
and $1 in 1998, 1997 and 1996, respectively, all of which related to
modifications of stock option terms.
 
    MediaOne Group has adopted the disclosure provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation," but continues to account for the Plan
under APB Opinion No. 25. Had compensation cost for the Plan been determined
consistent with the fair value based accounting method under SFAS No. 123, the
pro forma net income and earnings per share for both the MediaOne Group Stock
and Communications Stock would have been the following.

    The fair value based method of accounting for stock-based compensation plans
under SFAS No. 123 recognizes the value of options granted as compensation cost
over the options' vesting period and has not been applied to options granted
prior to January 1, 1995. Accordingly, the resulting pro forma compensation cost
is not representative of what compensation cost will be in future years.
 
    Following are the weighted-average assumptions used in connection with the
Black-Scholes option-pricing model to estimate the fair value of options granted
during 1998, 1997 and 1996:

    A total of 6,088,849, 8,733,782 and 5,523,728 MediaOne Group Stock options
were granted in 1998, 1997 and 1996, respectively. A total of 9,491,642 and
3,624,602 Communications Stock options were granted in 1997 and 1996,
respectively. Included in the total grants were 249,827 of modified MediaOne
Group Stock options and 198,027 of modified Communications Stock options
revalued as new grants during 1996. The modified MediaOne Group Stock options
were not significant in 1998 and 1997, and the Communications Stock options were
not significant during 1997. Including the modified options, the
weighted-average grant date fair value was $7.10 for MediaOne Group Stock
options and $3.87 for Communications Stock options in 1996. The exercise price
of MediaOne Group and Communications Stock options, excluding modified options,
equals the market price on the grant date. The exercise prices of modified stock
options may be greater or less than the market price on the revaluation date.
 
    Approximately 4,046,000 and 2,700,000 shares of MediaOne Group Stock were

NOTE 19: EMPLOYEE BENEFITS
 
MEDIAONE GROUP PLANS
 
    Effective on the Separation, MediaOne Group established a new defined
benefit pension plan and a new retiree health care and life insurance plan for
certain of its employees. A portion of the existing assets of the Old U S WEST
pension plan were transferred at fair value to the MediaOne Group pension plan
such that the ratio of plan assets to plan liabilities, calculated on a
projected benefit obligation basis, was the same for the MediaOne Group and New
U S WEST pension plans. The existing assets of the Old U S WEST postretirement
plan were transferred to MediaOne Group in a similar manner, such that the ratio
of plan assets to plan liabilities, calculated on an accumulated postretirement
benefit obligation basis, was the same for MediaOne Group and New U S WEST.
 
    The MediaOne Group defined benefit pension plan covers substantially all of
its employees, except for foreign national employees. Management benefits are
based on a final pay formula and MediaOne Group uses the projected unit credit
method for the determination of pension cost for financial reporting and funding
purposes. MediaOne Group's policy is to fund amounts required under the Employee
Retirement Income Security Act of 1974; no funding was required in 1998, 1997
nor 1996.
 
    MediaOne Group also sponsors a nonqualified pension plan which pays
supplemental pension benefits to key executives in addition to amounts received
under the MediaOne Group pension plan. The obligation and annual expense for
this plan are included in the 1998 pension detail below.
 
    MediaOne Group provides certain health care and life insurance benefits to
retired employees. MediaOne Group uses the projected unit credit method for the
determination of postretirement medical and life costs for financial reporting
purposes.
 
    The components of the 1998 net periodic benefit cost for pension benefits
and for other postretirement benefits were $3 and $2, respectively, during the
year.
 
    Below is a reconciliation of the change in the fair value of the plan assets
for the pension and postretirement plans for 1998:

OLD U S WEST PLANS
 
    Prior to the Separation, MediaOne Group participated in the employee
benefits plans sponsored by Old U S WEST. Since both MediaOne Group and New U S
WEST belonged to a single pension and postretirement plan, assets were not
segregated until Separation. Pension and postretirement benefit costs were
allocated to MediaOne Group based on the ratio of MediaOne Group's service cost
to

    In connection with the Continental Acquisition, the Company has acquired
operating loss carryforwards of approximately $217 for federal income tax
purposes, expiring in various years through 2011. The Company also acquired
investment tax credit carryforwards of approximately $50, expiring in various
years through 2005. Due to potential use limitations, a valuation allowance of
$279 has been established for the carryforwards and for a deferred tax asset
associated with an investment. If the realization of the carryforwards or
deferred tax asset becomes more likely than not in future periods, any reduction
in the valuation allowance will be allocated to reduce goodwill and acquired
intangible assets.
 
    The current portion of the deferred tax asset was $74 and $102 at December
31, 1998 and 1997, respectively, resulting primarily from compensation-related
items and other accrued expenses. The net deferred tax liability includes $669
in 1997 related to the capital assets segment. Foreign operations contributed
pretax losses of $336, $604 and $362 during 1998, 1997 and 1996, respectively.

NOTE 22: SUBSEQUENT EVENTS
 
    CABLE SYSTEMS.  On February 2, 1999, MediaOne Group and Time Warner Cable, a
division of Time Warner and TWE, signed a definitive agreement to trade certain
cable systems. MediaOne Group will trade cable systems in Ohio, Maine and
California serving approximately 350,000 subscribers, while Time Warner Cable
will trade cable systems in Massachusetts, New Hampshire and Georgia serving
approximately 310,000 subscribers. MediaOne Group will also receive cash from
the trade. The transaction is expected to close in 1999.
 
    On March 2, 1999, MediaOne Group and Cox Communications, Inc. ("Cox") signed
a definitive agreement to trade certain cable systems. MediaOne Group will trade
cable systems in Connecticut and Rhode Island serving approximately 51,000
subscribers, while Cox will trade cable systems in Massachusetts serving
approximately 54,000 subscribers. MediaOne Group will also pay cash for the
trade. The transaction is expected to close during the third quarter of 1999,
subject to legal and regulatory approval.
 
    SHAREHOLDER RIGHTS PLAN.  On February 9, 1999, the Board of Directors
approved a new shareholder rights plan to replace the existing plan upon
expiration. The new rights expire on April 6, 2009. The new shareholder rights
plan contains terms similar to the original plan.
 
    INVESTMENT IN AIRTOUCH COMMUNICATIONS.  On January 15, 1999, AirTouch
entered into a preliminary agreement with Vodafone Group Public Limited Company
("Vodafone") to merge its operations with a subsidiary of Vodafone. The proposed
terms of the preliminary merger agreement indicate that the outstanding common
shares of AirTouch would be converted into the right to receive five ordinary
shares of Vodafone and $9.00 in cash per AirTouch common share held. MediaOne
Group currently owns approximately 59.3 million shares of AirTouch common stock,
of which a maximum of 29 million shares could be used in the future to
extinguish the Exchangeable Notes outstanding. See Note 10--Debt--to the
Consolidated Financial Statements.
 
    INVESTMENT IN PRIMESTAR.  On January 22, 1999, PrimeStar announced that it
had reached an agreement with Hughes Electronics Corporation ("Hughes") to sell
its rights to acquire certain high-power satellite assets to Hughes for
approximately $35 in cash and the assumption by Hughes of $465 of certain
advances made by Old PrimeStar to Tempo Satellites, Inc. In addition, PrimeStar
agreed to sell its DBS medium-power business and assets to Hughes for
approximately $1.1 billion in cash and 4.871 million shares of General Motors
Class H common stock. The sales are contingent upon the receipt of various
regulatory approvals and the consent of certain third parties, including
PrimeStar lenders.
 
    OPTUS SHARES.  During the first quarter of 1999, MediaOne Group sold its
investment in the 50 million Optus shares held as of year-end 1998, for net
proceeds of $121 and a pre-tax gain of $119. In addition, during the first
quarter of 1999, MediaOne Group received 13.6 million Optus shares as a result
of having met certain performance measures at Optus, and purchased 5.6 million
additional Optus shares related to the Company's anti-dilution rights. MediaOne
Group is currently in the process of disposing of its remaining investment in
Optus shares.
 
    COMCAST MERGER.  On March 22, 1999, MediaOne Group announced that it had
entered into a merger agreement with Comcast Corporation ("Comcast") whereby

Comcast. The merger agreement calls for MediaOne Group common shareowners to
receive 1.1 shares of Comcast Class A Special Common Stock for each share of
MediaOne Group common stock held. The transaction will be tax-free to MediaOne
Group shareowners. Subject to the approval of both shareowner groups, and
various federal, state and local regulatory bodies, the merger could be
completed as early as year-end 1999. While the merger agreement prohibits
MediaOne Group from soliciting competing acquisition proposals, MediaOne Group
may, subject to compliance with the terms of the merger agreement and payment of
a $1.5 billion fee to Comcast, accept a superior proposal that is submitted
within 45 days of the date of the merger agreement.
 
NOTE 23: NET INVESTMENT IN ASSETS HELD FOR SALE
 
    As of December 31, 1998, the disposal of assets held for sale of the capital
assets segment was substantially completed. Therefore, the Consolidated Balance
Sheet at December 31, 1998 includes the accounts of the capital assets segment.
Prior to this time, the capital assets segment had been accounted for in
accordance with Staff Accounting Bulletin No. 93, issued by the SEC, which
required discontinued operations not disposed of within one year of the
measurement date to be accounted for prospectively in continuing operations as a
"net investment in assets held for sale." The remaining assets of the capital
assets segment primarily represent long term lease finance receivables which
will be run-off. These receivables are reflected in "Other Assets" in the
Consolidated Balance Sheet for 1998. Beginning in 1999, the operations of the
capital assets segment will also be reflected in the Consolidated Statements of
Operations.
 
    MediaOne Real Estate, Inc. ("Real Estate") sold various assets during 1998,
1997 and 1996 for proceeds of $182, $88 and $156, respectively. The sales
proceeds were in line with estimates. Proceeds from sales were primarily used to
repay related debt. As of December 31, 1998, the Company had substantially
completed the liquidation of this portfolio.
 
    Building sales and operating revenues of the capital assets segment were
$208, $116 and $223 in 1998, 1997 and 1996 , respectively. During 1998, 1997 and
1996, income or losses from the capital assets segment were deferred and
included within the reserve for assets held for sale.

    Finance receivables primarily consist of contractual obligations under
long-term leases with maturity dates ranging from 1999 to 2016 that MediaOne
Group intends to run off. Certain leases contain renewal options and buyout
provisions. These long-term leases consist mostly of leveraged leases related to
aircraft and power plants. For leveraged leases, the cost of the assets leased
is financed primarily through nonrecourse debt which is netted against the
related lease receivable. The components of finance receivables follow.

NOTE 24: DISCONTINUED OPERATIONS
 
    In accordance with Accounting Principles Board Opinion No. 30, "Reporting
the Results of Operations--Reporting the Effects of Disposal of a Segment of a
Business and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions," the Consolidated Financial Statements reflect New U S WEST as a
discontinued operation. The assets and liabilities, revenues and expenses, and
the cash flows of New U S WEST have been separately classified in the
Consolidated Balance Sheets, Statements of Operations, and Statements of Cash
Flows.
 
    The Company has accounted for the distribution of New U S WEST common stock
to the holders of Communications Stock, and to the holders of MediaOne Group
Stock for the Dex Alignment as a discontinuance of the businesses comprising New
U S WEST. The measurement date for discontinued operations accounting purposes
is June 4, 1998, the date upon which Old U S WEST's shareowners approved the
Separation. Because the distribution was non pro-rata, as compared with the
businesses previously attributed to Old U S WEST's two classes of shareowners,
it was accounted for at fair value. The distribution resulted in a gain of
$24,461, net of $114 of Separation costs (net of tax benefits of $37).
Separation costs included cash payments under severance agreements of $45 and
financial advisory, legal, registration fee, printing and mailing costs.
Separation costs also included a one-time payment to terminate the sale of the
Minnesota cable systems.
