  2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
  
       New Accounting Pronouncement
       In June 1998, the Financial  Accounting  Standards  Board  ("FASB")  issued
       Statement of Financial  Accounting  Standards ("SFAS") No. 133, "Accounting
       for Derivative  Instruments and Hedging Activities." This statement,  which
       establishes  accounting and reporting standards for derivatives and hedging
       activities,  is effective for fiscal years  beginning  after June 15, 1999.
       Upon the  adoption  of SFAS No. 133,  all  derivatives  are  required to be
       recognized  in the  statement  of  financial  position as either  assets or
       liabilities and measured at fair value. The Company is currently evaluating
       the impact the adoption of SFAS No. 133 will have on its financial position
       and results of operations.
  
       Comprehensive Income (Loss)
       In June  1997,  the FASB  issued  SFAS No.  130,  "Reporting  Comprehensive
       Income."  This  statement,  which  establishes  standards for reporting and
       disclosure  of  comprehensive  income,  is effective for interim and annual
       periods beginning after December 15, 1997. The Company adopted SFAS No. 130
       effective January 1, 1998. Total  comprehensive  income (loss) for the nine
       and three  months  ended  September  30, 1998 and 1997 was $749.5  million,
       ($62.2)  million,  $760.0  million and $36.2 million,  respectively.  Total
       comprehensive  income (loss) includes net income (loss),  unrealized  gains
       (losses) on marketable  securities and foreign currency  translation  gains
       (losses) for the periods presented.
  
       Earnings (Loss) for Common Stockholders Per Common Share
       Earnings  (loss) for common  stockholders  per common  share is computed by
       dividing net income (loss),  after deduction of preferred stock  dividends,
       by the weighted  average  number of common  shares  outstanding  during the
       period on a basic and diluted basis.

       Put  options  sold by the  Company  on 2.75  million  shares of its Class A
       Special Common stock (see Note 6) were outstanding  during the three months
       ended  September  30,  1998 but were not  included  in the  computation  of
       Diluted EPS as the options' exercise price was less than the average market
       price of the Company's Class A Special Common Stock during the period.
  
       For the nine and three  months ended  September  30,  1997,  the  Company's
       potential common shares of 61.2 million shares have an antidilutive  effect
       on loss for common  stockholders  per  common  share for the  periods  and,
       therefore,  have not been used in determining  the total  weighted  average
       number of common shares outstanding.

  3.   SIGNIFICANT EVENTS
  
       Sale of Comcast UK Cable
       In February 1998, Comcast UK Cable Partners Limited ("Comcast UK Cable"), a
       consolidated subsidiary of the Company, entered into a definitive agreement
       to be acquired (the "NTL  Transaction")  by NTL  Incorporated  ("NTL"),  an
       alternative  telecommunications  company in the United Kingdom ("UK").  The
       Company received 4.8 million shares of NTL common stock in exchange for all
       of the shares of Comcast UK Cable held by the Company  upon  closing of the
       NTL Transaction on October 29, 1998.  Certain  conditions  agreed to in the
       NTL Transaction restrict the Company's ability to sell the NTL common stock
       to be  received  for a period  of 150 days  after  the  closing  of the NTL
       Transaction. The Company's investment in NTL common stock had a fair value,
       prior to  consideration  of the  restrictions  on the NTL common stock,  of
       approximately  $225.4  million,  based on the quoted market price of $46.75
       per share of NTL common stock as of October 29, 1998.  As of September  30,
       1998 and for the nine months then ended, the assets and revenues of Comcast
       UK Cable totaled $866.0 million and $93.7 million, respectively.

       AT&T Acquisition of TCGI
       In January  1998,  AT&T Corp.  ("AT&T")  entered into a  definitive  merger
       agreement with Teleport  Communications Group, Inc. ("TCGI").  Upon closing
       of the merger  (the  "AT&T  Transaction")  on July 23,  1998,  the  Company
       received 24.2 million shares of unregistered  AT&T common stock in exchange
       (the  "Exchange")  for the 25.6 million shares of TCGI Class B Common Stock
       held by the Company (see Note 4). As a result of the Exchange,  the Company
       recognized  a pre-tax  gain of  $1.092  billion  during  the nine and three
       months ended September 30, 1998,  representing  the difference  between the
       fair value of the AT&T stock received and the Company's basis in TCGI. Such
       gain  is  included  in  investment   income  in  the  Company's   condensed
       consolidated  statement of operations and accumulated  deficit. The Company
       has registration rights, subject to customary restrictions, which allow the
       Company  to  effect a  registration  of the  AT&T  shares  received.  As of
       September  30,  1998,  the Company has  recorded  its  investment  in AT&T,
       classified as available for sale, at its estimated fair value.
  
       Acquisition of Jones Intercable
       In May 1998,  the  Company  agreed to  purchase  from BCI  Telecom  Holding
       ("BTH") 6.4 million Class A Common Shares in Jones Intercable, Inc. ("Jones
       Intercable"),  and a 49%  interest  in the BTH  subsidiaries  which were to
       continue  to own BTH's  remaining  6.4 million  shares of Jones  Intercable
       Class A Common  Stock.  At the same  time,  the  Company  agreed to acquire
       approximately  2.9 million shares of Common Stock of Jones  Intercable (the
       "Control  Shares"),  if and when  acquired by BTH from  affiliates of Jones
       Intercable's controlling shareholder under an existing option (the "Control
       Option") to acquire such shares (which absent  extraordinary  circumstances
       would not have been  exercisable  until December 2001).  The Company was to
       purchase the remaining 51% of the BTH subsidiaries  when the Control Shares
       were acquired.  The Company,  BTH, Jones Intercable and Jones  Intercable's
       controlling  shareholder  agreed in August 1998 to  accelerate  the Control
       Option  to  permit  its  early  exercise  and  the  early  closing  of  the
       transactions  with BTH. At closing  (expected to occur in the first quarter
       of 1999,  subject to the receipt of  required  regulatory  approvals),  the
       Company  will pay BTH a total of $500  million in cash to acquire  the 12.8
       million shares of Jones Intercable Class A Common Stock and $200 million in
       cash to acquire the Control Shares. After closing, the Company will control
       approximately  37% of the economic and 47% of the voting  interest in Jones
       Intercable.  In addition,  the Control Shares will represent  shares having
       the right to elect  approximately  75% of the Board of  Directors  of Jones
       Intercable. The transaction will be funded either with new borrowings, with
       available  borrowings  under  existing  lines of credit or by other  means.
       Jones  Intercable,  a public  company,  owns or  manages  cable  operations
       serving approximately 1.0 million customers.

       Equity Method
       The Company records its proportionate interests in the net income (loss) of
       substantially  all of its  investees,  other  than  the UK  Investees  (see
       below), three months in arrears.  The Company holds interests  representing
       less than 20% of the total  outstanding  ownership  interests in certain of
       its equity  method  investees.  The equity method of accounting is utilized
       for  these  investments  based  on the  type of  investment  (e.g.  general
       partnership interest), board representation, participation in a controlling
       investor group,  significant  shareholder  rights or a combination of these
       and  other  factors.   The  Company's   recorded   investments  exceed  its
       proportionate  interests in the book value of the  investees' net assets by
       $141.2 million as of September 30, 1998 (primarily related to the Company's
       investments in The Golf Channel and Sprint PCS (see below)). Such excess is
       being amortized to equity in net income or loss, primarily over a period of
       twenty  years,  which  is  consistent  with  the  estimated  lives  of  the
       underlying assets. The

       (1) Net  loss  also  represents  loss  from  continuing  operations  before
           extraordinary  items and  cumulative  effect of changes  in  accounting

       (2) As a result of the  acquisition of E!  Entertainment  Television,  Inc.
           ("E!  Entertainment")  on March 31, 1997, the Company recorded a charge
           representing  the  cumulative  amount that would have been recorded had
           the Company accounted for its investment in E! Entertainment  under the
           equity  method since the date of initial  investment  (the  "Cumulative
           Charge"). Since the Company's proportionate share of E! Entertainment's
           cumulative losses was in excess of the Company's  historical cost basis
           in E!  Entertainment  and as  the  Company  was  under  no  contractual
           obligation  to fund the  losses  of E!  Entertainment,  the  Cumulative
           Charge was  limited  to the  Company's  historical  cost basis of $12.1
           million.  Such amount is included in equity in net losses of affiliates
           in the Company's  condensed  consolidated  statement of operations  and
           accumulated  deficit for the nine months ended September 30, 1997 as it

       Sprint  PCS.   The  Company,   Tele-Communications,   Inc.   ("TCI"),   Cox
       Communications,  Inc.  ("Cox," and  together  with the Company and TCI, the
       "Cable Partners") and Sprint  Corporation  ("Sprint," and together with the
       Cable  Partners,  the  "Parents"),  engage in the  wireless  communications
       business through a limited  partnership  known as "Sprint PCS." The Company
       made its  initial  investment  in 1994 to  acquire  a general  and  limited
       partnership  interest of 15% in Sprint PCS. As of September  30, 1998,  the
       Company had contributed $669.5 million to Sprint PCS. No additional amounts
       are due with  respect to the  balance  of the  Company's  original  funding
       commitment to Sprint PCS.

       In May  1998,  the  Parents  announced  an  agreement  (the  "Restructuring
       Agreement")  under which Sprint would assume total ownership and management
       control of Sprint PCS.
  
       At closing of the Restructuring Agreement, Sprint will issue a new class of
       Sprint stock (the "Sprint PCS Stock") to track the  performance of Sprint's
       combined wireless operations.  Initially,  in exchange for its interests in
       Sprint PCS, the Company will receive an  approximate  11.6% interest in the
       Sprint PCS Stock, consisting of approximately 47.2 million shares of Series
       2 Sprint PCS common stock,  approximately  2.2 million shares of Sprint PCS
       preferred  stock  (convertible  on  specified  terms to Series 2 Sprint PCS
       common stock) and warrants to purchase  approximately 3.0 million shares of
       Sprint PCS Stock. Under the Restructuring Agreement, Sprint will distribute
       its  interest  in the Sprint PCS Stock to its  existing  shareholders.  The
       Restructuring  Agreement  also  contemplates  a subsequent  initial  public
       offering ("IPO") of the Sprint PCS Stock. The Cable Partners'  interests in
       the Sprint  PCS Stock  would be  reduced  proportionately  by the amount of
       ownership  interests  issued in  connection  with an IPO, and in connection
       with any purchases made at that time by two of Sprint's major  shareholders
       under  existing   anti-dilution  rights  -  France  Telecom  S.A.  ("France
       Telecom") and Deutsche Telekom AG ("Deutsche Telekom").
  
       The Sprint PCS Stock will be divided  into three  categories:  (i) Series 1
       (one vote per share) to be held by the public, (ii) Series 2 (1/10 vote per
       share  other  than in class  votes) to be held by the Cable  Partners,  and
       (iii)  Series 3 (one  vote per  share)  to be held by  France  Telecom  and
       Deutsche Telekom. Under the terms of the Restructuring Agreement, the Cable
       Partners have registration rights, subject to customary restrictions, that,
       if used, would permit the monetization of their Sprint PCS holdings through
       equity offerings or derivatives.  If the Series 2 shares are transferred by
       a Cable Partner, the transferred shares become full vote Series 1 shares.
  
       On September 25, 1998, Sprint Corporation filed a preliminary  registration
       statement  with the  Securities  and  Exchange  Commission  (the  "SEC") to
       register up to $604.0 million in an IPO of its Sprint PCS Stock. The timing
       of the public offering can not yet be determined.
  
       On November 13, 1998, the Sprint  stockholders  approved the  Restructuring
       Agreement. The Restructuring Agreement is expected to close on November 23,
       1998, subject to the receipt of necessary regulatory approvals.
  
       TCGI. In April 1998, in connection  with an  acquisition,  TCGI issued 16.3
       million  shares of its Class A Common  Stock (the "TCGI  Acquisition").  In
       November 1997, TCGI filed a registration statement with the SEC to sell 7.3
       million  shares of TCGI Class A Common  Stock (the "TCGI  Offering").  As a
       result  of  the  TCGI  Acquisition  and  the  TCGI  Offering,  the  Company
       recognized a $157.8 million and $98.2 million increase in its proportionate
       share of TCGI's net assets as a gain from equity  offering of affiliate for
       the nine and three  months ended  September  30,  1998,  respectively.  The
       Company records its proportionate share of TCGI's net assets one quarter in
       arrears.
  
       UK Investees. As of September 30, 1998, Comcast UK Cable (see Note 3) holds
       a 27.5%  interest  in  Birmingham  Cable  Corporation  Limited  and a 50.0%
       interest in Cable London PLC.
  
       Comcast-Spectacor.  Effective  January 1,  1998,  the  Company's  condensed
       consolidated   financial   statements   include  the  accounts  of  Comcast
       Spectacor,  L.P.  ("Comcast-Spectacor"),  an affiliate previously accounted
       for under the equity method, due to certain call rights held by the Company
       which became exercisable effective January 16, 1998.
  
       Other.  The Company's other equity investees  include  investments in cable
       communications   (including   Garden  State   Cablevision   L.P.,  a  cable
       communications   company  serving  more  than  210,000  subscribers  as  of
       September   30,   1998  in  the   State   of  New   Jersey),   cellular/PCS
       telecommunications  and content  providers.  The Company  does not consider
       these other equity method investments to be individually significant to its
       consolidated financial position, results of operations or liquidity.
  
       Fair Value Method
       The Company  holds  unrestricted  equity  investments  in certain  publicly
       traded  companies,  with an  historical  cost  (including a $1.092  billion
       pre-tax gain  recognized  during the third quarter of 1998 - see Note 3) of
       $1.466 billion and $130.0 million as of September 30, 1998 and December 31,
       1997, respectively.  The Company has recorded these investments,  which are
       classified as available for sale, at their  estimated fair values of $1.985
       billion and

       $346.5   million  as  of   September   30,  1998  and  December  31,  1997,
       respectively.  The  unrealized  pre-tax  gains as of September 30, 1998 and
       December 31, 1997 of $518.9 million and $216.5 million, respectively,  have
       been reported in the Company's  condensed  consolidated  balance sheet as a
       component  of  stockholders'  equity,  net of related  deferred  income tax
       expense of $181.6 million and $75.8 million, respectively.
  
       In March 1998, the Company sold call options  relating to its  unrestricted
       equity investments in TCI, TCI Ventures Group, Inc. and Liberty Media Group
       common  stock  (together,  the "TCI  Stock") for $20.7  million.  Such call
       options expire between March and September 1999.  During the nine and three
       months ended September 30, 1998, the Company  recorded  pre-tax  investment
       (expense) income of ($32.1) million and $8.1 million, respectively, related
       to changes in the value of the call options.
  
       During the nine and three months  ended  September  30,  1998,  the Company
       recorded a pre-tax  loss of $91.2  million  on  certain of its  investments
       based on a decline in value that is considered  other than temporary.  Such
       pre-tax loss is recorded in investment  income in the  Company's  condensed
       consolidated statement of operations and accumulated deficit.
  
  5.   LONG-TERM DEBT
  
       Debt Offering
       On November 10, 1998,  the  Company,  through its wholly owned  subsidiary,
       Comcast Cable Communications,  Inc. ("Comcast Cable") announced that it has
       sold $800.0 million  aggregate  principal  amount of 6.20% senior notes due
       2008 in a public offering (the  "Offering").  Interest on the notes will be
       payable semiannually on May 15 and November 15 of each year, commencing May
       15, 1999. The notes are redeemable only upon maturity on November 15, 2008.
       The Company  expects to use all of the net  proceeds  from the Offering for
       general corporate  purposes.  The Offering is expected to close on November
       16, 1998.
  
       Redemption of 1 1/8% Debentures
       In March 1998,  the Company  completed the redemption of its $541.9 million
       principal amount 1 1/8% discount  convertible  subordinated  debentures due
       2007 (the "1 1/8%  Debentures").  The Company issued 10.4 million shares of
       its  Class A  Special  Common  Stock  upon  conversion  of  $540.2  million
       principal amount of 1 1/8% Debentures  while $1.7 million  principal amount
       of 1 1/8% Debentures was redeemed for cash at a redemption price of 67.112%
       of  the  principal   amount,   together  with  accrued  interest   thereon.
       Stockholders'  equity was increased by the full amount of 1 1/8% Debentures
       converted plus accrued interest,  less unamortized debt acquisition  costs.
       Unamortized  debt  acquisition  costs  related  to  the 1  1/8%  Debentures
       redeemed for cash were not significant. The issuance of the Company's Class
       A Special  Common Stock upon  conversion  of the 1 1/8%  Debentures  had no
       impact on the Company's condensed  consolidated statement of cash flows due
       to its noncash nature.
  
       Interest Rates
       As of September  30, 1998 and December 31, 1997,  the  Company's  effective
       weighted  average interest rate on its long-term debt outstanding was 8.39%
       and 8.36%, respectively.
  
       Lines of Credit
       As of  November  2, 1998,  certain  subsidiaries  of the Company had unused
       lines of credit of $870.5 million, $370.5 million of which is restricted by
       the  covenants of the related debt  agreements  and to  subsidiary  general
       purposes and dividend declaration.
  
  6.   STOCKHOLDERS' EQUITY
  
       Repurchase Program
       In September  1998,  the Company  announced that its Board of Directors had
       authorized a market repurchase program (the "Repurchase  Program") pursuant
       to which  the  Company  may  purchase,  in the open  market  or in  private
       transactions  up  to  $500.0  million  of  its  outstanding  common  equity
       securities,  subject to certain restrictions and market conditions. Through
       September 30, 1998, the Company had repurchased  shares of its common stock

       Company had repurchased  additional  shares for aggregate  consideration of
       $3.4 million.  In  conjunction  with the Repurchase  Program,  in September
       1998,  the Company sold put options on 2.75  million  shares of its Class A
       Special Common Stock.  The put options give the holder the right to require
       the Company to repurchase such shares at specified prices on specific dates
       during the period  from April  through  September  1999.  Proceeds of $11.4
       million  from the sale of these put options  were  credited  to  additional
       capital.  The amount the Company  would be obligated  to pay to  repurchase
       such shares if all outstanding put options were exercised,  totaling $111.2
       million,  has  been  reclassified  to a  temporary  equity  account  in the
       Company's condensed consolidated balance sheet as of September 30, 1998.
  
       In April 1997, in connection with the Company's  previous market repurchase
       program which  terminated in May 1997,  the Company sold put options on 2.0
       million shares of its Class A Special Common Stock. The put options,  which
       expired unexercised during April and May 1998, gave the holder the right to
       require the  Company to  repurchase  such  shares at a  specified  price on
       specific  dates  in  April  and May  1998.  Upon  expiration,  the  Company
       reclassified $31.4 million,  the amount it would have been obligated to pay
       to repurchase such shares had the put options been  exercised,  from common
       equity  put  options  to  additional  capital  in the  Company's  condensed
       consolidated balance sheet.
  
  7.   STATEMENT OF CASH FLOWS - SUPPLEMENTAL INFORMATION
  
       The Company  made cash  payments  for  interest of $334.1  million,  $303.4
       million,  $71.5 million and $69.6 million  during the nine and three months
       ended September 30, 1998 and 1997, respectively.
  
       The Company made cash  payments for income taxes of $105.2  million,  $89.7
       million,  $17.1 million and $14.7 million  during the nine and three months
       ended September 30, 1998 and 1997, respectively.
  
       During the three months ended  September 30, 1998, the Company  settled all
       issues  primarily  related to the  deductibility  of  amortization of cable
       television  distribution  rights  raised by the  Internal  Revenue  Service
       ("IRS")  in its  examination  of QVC,  Inc.,  a majority  owned  subsidiary
       ("QVC"),  through  fiscal  tax year 1993.  Such  settlement  resulted  in a
       reversal of previously recorded deferred tax liabilities of $135.5 million.
       As a result of the settlement, the Company recorded an adjustment to reduce
       goodwill by $119.7  million  during the three  months ended  September  30,
       1998.  Such  adjustment  has been  excluded  from the  Company's  condensed
       consolidated statement of cash flows due to its noncash nature.
  
  8.   COMMITMENTS AND CONTINGENCIES
  
       The Company is subject to legal  proceedings  and claims which arise in the
       ordinary course of its business.  In the opinion of management,  the amount
       of ultimate  liability  with respect to these  actions will not  materially
       affect the  financial  position,  results of operations or liquidity of the
       Company.

  ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
            RESULTS OF OPERATIONS
  
  Overview
  
  The Company has  experienced  significant  growth in recent  years both  through
  strategic  acquisitions and growth in its existing  businesses.  The Company has
  historically  met its cash  needs for  operations  through  its cash  flows from
  operating   activities.   Cash   requirements   for   acquisitions  and  capital
  expenditures have been provided through the Company's  financing  activities and
  sales of long-term  investments,  as well as its existing cash, cash equivalents
  and short-term investments.
  
  General Developments of Business
  
  See Note 3 to the Company's condensed consolidated financial statements included
  in Item 1.
  
  Liquidity and Capital Resources
  
  Cash, Cash Equivalents,  Short-term  Investments and Investments,  Available for
  Sale The Company has traditionally  maintained  significant levels of cash, cash
  equivalents,  short-term investments and investments, available for sale to meet
  its  short-term  liquidity  requirements.  Cash,  cash  equivalents,  short-term
  investments  and  investments,  available for sale as of September 30, 1998 were
  $2.138 billion.  As of September 30, 1998, $406.1 million of the Company's cash,
  cash equivalents,  short-term investments and investments, available for sale is
  restricted  to use by  subsidiaries  of the Company under  contractual  or other
  arrangements,  including $146.8 million which is restricted to use by Comcast UK
  Cable Partners Limited  ("Comcast UK Cable"),  a consolidated  subsidiary of the
  Company  (see  Note  3  to  the  Company's  condensed   consolidated   financial
  statements).
  
  The Company's cash  equivalents and short-term  investments are recorded at cost
  which  approximates  their fair value.  As of  September  30,  1998,  short-term
  investments have a weighted average maturity of approximately  five months.  The
  Company's investments, available for sale are recorded at fair value.
  
  Investments
  See Notes 3 and 4 to the Company's condensed  consolidated  financial statements
  included in Item 1.
  
  The Company does not have any significant  contractual  commitments with respect
  to any of its investments.  However, to the extent the Company does not fund its
  investees'  capital  calls,  it  exposes  itself to  dilution  of its  ownership
  interests. The Company continually evaluates its existing investments as well as
  new investment opportunities.
  
  Financing
  See Notes 5 and 6 to the Company's condensed  consolidated  financial statements
  included in Item 1.
  
  As of September 30, 1998 and December 31, 1997,  the Company's  long-term  debt,
  including current portion, was $6.704 billion and $6.691 billion,  respectively,
  of which 22.1% and 17.1%, respectively, was at variable rates.
  
  The Company may from time to time, depending on certain factors including market
  conditions, make optional repayments on its debt obligations,  which may include
  open market repurchases of its outstanding public notes and debentures.
  
  Year 2000 Issue
  
  The Year 2000 Issue is the result of computer  programs  being written using two
  digits rather than four to define the applicable year.  Certain of the Company's
  computer programs that have  date-sensitive  software may recognize a date using
  "00" as the year 1900 rather than the year 2000 (the "Year 2000 Issue"). If this
  situation   occurs,   the  potential  exists  for  computer  system  failure  or
  miscalculations   by  computer   programs,   which  could  cause  disruption  of
  operations.

                          QUARTER ENDED SEPTEMBER 30, 1998
  
  
  The Company is in the process of  evaluating  and  addressing  the impact of the
  Year 2000 Issue on its operations to ensure that its information  technology and
  business  systems  recognize  calendar Year 2000.  The Company is utilizing both
  internal and external  resources in  implementing  its Year 2000 program,  which
  consists of the following phases:
  
  Assessment Phase
  Structured evaluation,  including a detailed inventory outlining the impact that
  the Year 2000 Issue may have on current operations.
  
  Detailed Planning Phase
  Establishment of priorities, development of specific action steps and allocation
  of resources to address the issues identified in the Assessment Phase.
  
  Conversion Phase
  Implementation of the necessary system modifications as outlined in the Detailed
  Planning Phase.
  
  Testing Phase
  Verification that the modifications  implemented in the Conversion Phase will be
  successful  in resolving  the Year 2000 Issue so that all  inventory  items will
  function properly, both individually and on an integrated basis.
  
  Implementation Phase
  Final roll-out of fully tested components into an operational unit.
  
  Based on an inventory  conducted in 1997,  the Company has  identified  computer
  systems that will require modification or replacement so that they will properly
  utilize dates beyond December 31, 1999. Many of the Company's  critical  systems
  are new and are already Year 2000 compliant as a result of the recent rebuild of
  many of the Company's cable  communications  systems and the implementation of a
  fully digital  cellular  communications  network.  In addition,  the Company has
  initiated  communications  with all of its  significant  software  suppliers and
  service  bureaus to determine their plans for remediating the Year 2000 Issue in
  their software which the Company uses or relies upon.
  
  As of September  30, 1998,  the Company is in the  Conversion  Phase of its Year
  2000  remediation  program and has entered  the  Testing  Phase with  respect to
  certain of its key systems. Through September 30, 1998, the Company has incurred
  approximately $5.0 million in connection with its Year 2000 remediation program.
  The Company  estimates that it will incur between  approximately  $10 million to
  $20 million of additional  expense through  December 1999 in connection with its
  Year  2000  remediation   program.   The  Company's  estimate  to  complete  the
  remediation plan includes the estimated time associated with mitigating the Year
  2000 Issue for third party software. However, there can be no guarantee that the
  systems of other  companies  on which the Company  relies will be converted on a
  timely basis,  or that a failure to convert by another  company would not have a
  material adverse effect on the Company.
  
  Management of the Company will continue to  periodically  report the progress of
  its Year 2000 remediation  program to the Audit Committee of the Company's Board
  of  Directors.  The Company  plans to complete the Year 2000  mitigation  by the
  third  quarter of 1999.  Management  of the  Company  has  investigated  and may
  consider  potential  contingency plans in the event that the Company's Year 2000
  remediation program is not completed by that date.
  
  The costs of the project and the date on which the Company plans to complete the
  Year  2000  modifications  and  replacements  are  based  on  management's  best
  estimates,  which were derived using  assumptions of future events including the
  continued   availability  of  resources  and  the  reliability  of  third  party
  modification plans. However, there can be no guarantee that these estimates will
  be  achieved  and actual  results  could  differ  materially  from those  plans.
  Specific factors that may cause such material  differences  include, but are not
  limited to, the availability  and cost of personnel with  appropriate  necessary
  skills and the  ability to locate and  correct all  relevant  computer  code and
  similar uncertainties.
  
  The  Company  believes  that  with   modifications  to  existing   software  and
  conversions to new software,  the Year 2000 Issue can be mitigated.  However, if
  such  modifications and conversions are not made, or are not completed within an
  adequate time frame, the Year 2000 Issue could have a material adverse impact on
  the operations of the Company.

  The telecommunications  industry,  including cable and cellular  communications,
  and the electronic  retailing industry are experiencing  increasing  competition
  and rapid technological changes. The Company's future results of operations will
  be affected by its  ability to react to changes in the  competitive  environment
  and by its ability to implement new technologies.  However, the Company believes
  that competition,  technological  changes and its history of significant  losses
  will not significantly affect its ability to obtain financing.
  
  The Company  believes  that it will be able to meet its  current  and  long-term
  liquidity and capital  requirements,  including fixed charges,  through its cash
  flows from operating  activities,  existing cash, cash  equivalents,  short-term
  investments,  investments,  available  for sale and  lines of  credit  and other
  external financing.
  
  Statement of Cash Flows
  
  Cash and cash equivalents  increased $21.3 million as of September 30, 1998 from
  December 31, 1997 and  increased  $242.3  million as of September  30, 1997 from
  December 31, 1996.  Increases in cash and cash  equivalents  resulted  from cash
  flows from  operating,  financing and investing  activities  which are explained
  below.
  
  Net cash provided by operating  activities amounted to $818.6 million and $742.1
  million for the nine months ended September 30, 1998 and 1997, respectively. The
  increase of $76.5  million is  principally  due to the increase in the Company's
  operating  income  before   depreciation  and  amortization   (see  "Results  of
  Operations")  and  changes  in  working  capital  as a result  of the  timing of
  receipts  and  disbursements,  including  the  effects of the  consolidation  of
  Comcast  Spectacor,  L.P.  ("Comcast-Spectacor")  effective January 1, 1998 (see
  Note 4 to the Company's condensed  consolidated financial statements included in
  Item  1)  and  the  acquisition  of  E!  Entertainment  Television,   Inc.  ("E!
  Entertainment") on March 31, 1997 (the "E! Acquisition").
  
  Net cash provided by financing  activities was $134.2 million and $345.3 million
  for the nine months ended September 30, 1998 and 1997, respectively.  During the

  Results of Operations
  
  The  effects of the  Company's  recent  acquisitions  and the  consolidation  of
  Comcast-Spectacor  effective  January 1, 1998,  as well as  increased  levels of
  capital  expenditures,  were to increase  the  Company's  revenues  and expenses
  resulting  in  increases  in  its  operating  income  before   depreciation  and
  amortization,  depreciation expense,  amortization expense and interest expense.
  In addition,  the  Company's  equity in net losses of  affiliates  has increased
  principally  as a result of the  start-up  nature of  certain  of the  Company's
  equity investees (see "Consolidated Analysis").

  (1)  Operating income before  depreciation and amortization is commonly referred
       to in the Company's  businesses as "operating  cash flow."  Operating  cash
       flow is a measure of a company's  ability to  generate  cash to service its
       obligations, including debt service obligations, and to finance capital and
       other  expenditures.  In part due to the  capital  intensive  nature of the
       Company's  businesses  and the  resulting  significant  level  of  non-cash
       depreciation  expense  and  amortization  expense,  operating  cash flow is
       frequently  used  as one of  the  bases  for  comparing  businesses  in the
       Company's industries, although the Company's measure of operating cash flow
       may not be  comparable  to similarly  titled  measures of other  companies.
       Operating  cash flow does not purport to  represent  net income or net cash
       provided  by  operating  activities,  as  those  terms  are  defined  under
       generally accepted accounting

  The  respective  increases in net sales of $210.5  million and $83.3 million for
  the nine and three  month  periods  from 1997 to 1998 are due to the  effects of
  6.2% and 4.3% increases in the average number of homes receiving QVC services in
  the United  States  ("US"),  increases in net sales per home and 12.5% and 11.0%
  increases in the average  number of homes  receiving  QVC services in the United
  Kingdom.
  
  The increases in cost of goods sold are  primarily  related to the growth in net
  sales.
  
  Of the $22.1 million increase in operating,  selling, general and administrative
  expenses  for the  nine  month  period  from  1997 to  1998,  $21.4  million  is
  attributable  to higher  variable  costs  associated  with the increase in sales
  volume. The remaining increase is attributable to personnel and facilities based
  costs   associated  with  Studio  Park,   QVC's  new   production,   studio  and
  administrative  facility  which  was  opened in the  third  quarter  of 1997 and
  expansion in the UK and Germany,  partially  offset by savings in marketing  and
  promotional costs in the US. Of the $8.7 million increase in operating, selling,
  general and  administrative  expenses  for the three  month  period from 1997 to
  1998, $8.9 million is attributable to higher variable costs  associated with the
  increase in sales volume.  The remaining  decrease is primarily  attributable to
  reduced marketing and promotional costs in the US.

  Service income increased by $2.6 million and $1.6 million for the nine and three
  month periods from 1997 to 1998, as  subscriber  growth was offset,  in part, by
  the effects of increased  use of  promotional  and free minute plans  offered to
  subscribers.  These plans  generally  have higher  access fees and  increase the
  minutes of use per subscriber while lowering the average rate per minute of use.
  
  The respective  $6.5 million and $5.6 million  increases in operating,  selling,
  general and  administrative  expenses for the nine and three month  periods from
  1997 to  1998  are  primarily  the  result  of  increases  in  commission  costs
  associated with more gross sales in 1998.
  
  Consolidated Analysis
  
  The respective $65.6 million and $18.3 million increases in depreciation expense
  for  the  nine  and  three  month  periods  from  1997  to  1998  are  primarily
  attributable to the effects of capital  expenditures,  increased losses on asset
  disposals in connection with the Company's domestic cable communications rebuild
  activities, the consolidation of Comcast- Spectacor and the acquisition of cable
  communications systems.
  
  The respective $28.1 million and $11.4 million increases in amortization expense
  for  the  nine  and  three  month  periods  from  1997  to  1998  are  primarily
  attributable to the effects of the consolidation of Comcast-Spectacor.
  
  The $14.5  million  increase in interest  expense for the nine month period from
  1997 to 1998 is attributable to the effects of capitalized  interest  associated
  with the  Company's  investment  in Sprint  PCS  during  the nine  months  ended
  September 30, 1997, the consolidation of  Comcast-Spectacor,  the E! Acquisition
  and an increase in the  Company's  effective  weighted  average  interest  rate,
  offset,  in part, by lower levels of debt outstanding.  The Company  anticipates
  that, for the foreseeable future, interest expense will be a significant cost to
  the Company and will have a significant  adverse effect on the Company's ability
  to realize net  earnings.  The Company  believes it will  continue to be able to
  meet its  obligations  through its ability  both to  generate  operating  income
  before depreciation and amortization and to obtain external financing.
  
  In January 1998, AT&T Corp.  ("AT&T") entered into a definitive merger agreement
  with Teleport  Communications Group Inc. ("TCGI"). Upon closing of the merger on
  July 23, 1998,  the Company  received 24.2 million shares of  unregistered  AT&T
  common stock in exchange (the  "Exchange") for 25.6 million shares of TCGI Class
  B common stock held by the  Company.  As a result of the  Exchange,  the Company
  recognized a pre-tax gain of $1.092 billion during the

  nine and three months ended  September  30, 1998,  representing  the  difference
  between the fair value of the AT&T stock  received  and the  Company's  basis in
  TCGI.  Such gain is included in  investment  income in the  Company's  condensed
  consolidated statement of operations and accumulated deficit.
  
  During the nine and three months ended September 30, 1998, the Company  recorded
  a pre-tax loss of $91.2 million on certain of its investments based on a decline
  in value that is considered other than temporary.  Such pre-tax loss is included
  in  investment  income in the  Company's  condensed  consolidated  statement  of
  operations and accumulated deficit.
  
  In March 1998, the Company sold call options relating to its unrestricted equity
  investments in  Tele-Communications,  Inc. ("TCI"), TCI Ventures Group, Inc. and
  Liberty Media Group common stock (together,  the "TCI Stock") for $20.7 million.
  Such call options expire between March and September  1999.  During the nine and
  three months ended September 30, 1998, the Company recorded  pre-tax  investment
  (expense) income of ($32.1) million and $8.1 million,  respectively,  related to
  changes in the value of the call options. In addition, as of September 30, 1998,
  the Company  recorded net unrealized  gains (losses) of $47.9 million and ($5.2)
  million related to the TCI Stock,  net of deferred income tax expense  (benefit)
  of $25.8  million and ($2.8)  million,  to its  condensed  consolidated  balance
  sheet,  representing the increase in fair value of the TCI Stock during the nine
  and three months ended September 30, 1998, respectively.
  
  During the first  quarter of 1997 the Company  received  2.76 million  shares of
  TCGI  Class A Stock  from  TCGI in  exchange  for  the  Company's  shares  of an
  alternate  access  provider.  In May 1997, the Company sold all of its shares of
  TCGI Class A Stock for $68.9  million  and  recognized  a pre-tax  gain of $68.9
  million.  In February  1997,  the Company  sold  options to acquire 25.0 million
  shares of Nextel  Communications,  Inc.  ("Nextel")  common  stock to Nextel for
  $25.0 million and  recognized a pre-tax gain of $5.0  million.  In January 1997,
  the Company sold 1.27 million shares of Time Warner, Inc. ("Time Warner") common
  stock,  representing  the Company's  entire  interest in Time Warner,  for $48.6
  million and  recognized a pre-tax loss of $3.8  million.  Such pre-tax gains and
  pre-tax  loss are  included  in  investment  income in the  Company's  condensed
  consolidated statement of operations and accumulated deficit.
  
  The  $128.2  million  and $22.4  million  increases  in equity in net  losses of
  affiliates  for the nine and three month periods from 1997 to 1998 are primarily
  due to the effects of increased losses incurred by Sprint PCS (see Note 4 to the
  Company's condensed consolidated financial statements included in Item 1).
  
  In April 1998,  in  connection  with an  acquisition,  TCGI issued 16.3  million
  shares of its Class A Common Stock (the "TCGI  Acquisition").  In November 1997,
  TCGI filed a registration  statement with the Securities and Exchange Commission
  to sell 7.3  million  shares of TCGI Class A Stock (the "TCGI  Offering").  As a
  result of the TCGI Acquisition and the TCGI Offering,  the Company  recognized a
  $157.8 million and $98.2 million increase in its  proportionate  share of TCGI's
  net assets as a gain from equity  offering of  affiliate  for the nine and three
  months  ended  September  30,  1998,  respectively.   The  Company  records  its
  proportionate share of TCGI's net losses one quarter in arrears.
  
  The  fluctuations in other (income) expense for the nine and three month periods
  from 1997 to 1998 are primarily  attributable  to the effects of fluctuations in
  the foreign currency exchange rate.
  
  The $263.9  million and $300.5  million  increases in income tax expense for the
  nine and three month  periods from 1997 to 1998 are  primarily the result of the
  effects of changes in the Company's  income before taxes and minority  interest,
  and  non-deductible  foreign losses and  non-deductible  equity in net losses of
  affiliates.
  
  The $22.5 million and $21.9 million  decreases in minority interest for the nine
  and three month  periods  from 1997 to 1998 are  primarily  attributable  to the
  effects of changes in the net  income  (loss) of QVC and  Comcast UK Cable,  the
  consolidation of Comcast-Spectacor and the E! Acquisition.
  
  In connection with the redemption of certain indebtedness,  the Company expensed
  unamortized debt  acquisition  costs and incurred debt  extinguishment  costs of
  $4.7 million, resulting in an extraordinary loss, net of tax, of $3.0 million or
  $0.01 per common  share during the nine and three  months  ended  September  30,
  1998. In connection with the refinancing of certain  subsidiaries'  indebtedness
  and the redemption of debt, the Company  expensed  unamortized  debt acquisition
  costs and incurred debt extinguishment  costs of $39.8 million and $4.7 million,
  resulting in an  extraordinary  loss,  net

  of tax, of $25.9  million or $.08 per common  share and $3.1 million or $.01 per
  common  share  during  the nine and  three  months  ended  September  30,  1997,
  respectively.  For the nine and three months ended  September 30, 1998 and 1997,
  the Company's  earnings  (net income  (loss) plus income tax expense  (benefit),
  equity  in net  losses of  affiliates,  fixed  charges  (interest  expense)  and
  extraordinary  items) were $1.645 billion,  $555.7  million,  $1.280 billion and
  $186.2 million, respectively. Such earnings were adequate to cover the Company's
  fixed  charges  (including  interest  capitalized  of $18.0 million for the nine
  months ended  September  30, 1997) of $437.3  million,  $440.8  million,  $145.4
  million and $143.9  million for the nine and three  months ended  September  30,
  1998 and 1997,  respectively.  Fixed charges include non-cash  interest expense,
  net of interest capitalized,  of $37.4 million, $42.7 million, $11.3 million and
  $13.8  million for the nine and three months ended  September 30, 1998 and 1997,
  respectively.
  
  The  Company  believes  that  its  losses  will  not  significantly  affect  the
  performance of its normal business activities because of its existing cash, cash
  equivalents,  short-term  investments and  investments,  available for sale, its
  ability to generate  operating  income before  depreciation and amortization and
  its ability to obtain external financing.
  
  The  Company  believes  that  its  operations  are not  materially  affected  by
  inflation.

  2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
  
       New Accounting Pronouncement
       In June 1998, the Financial  Accounting  Standards  Board  ("FASB")  issued
       Statement of Financial  Accounting  Standards ("SFAS") No. 133, "Accounting
       for Derivative  Instruments and Hedging Activities." This statement,  which
       establishes  accounting and reporting standards for derivatives and hedging
       activities,  is effective for fiscal years  beginning  after June 15, 1999.
       Upon the  adoption  of SFAS No. 133,  all  derivatives  are  required to be
       recognized  in the  statement  of  financial  position as either  assets or
       liabilities and measured at fair value. The Company is currently evaluating
       the impact the adoption of SFAS No. 133 will have on its financial position
       and results of operations.
  
       Comprehensive Income (Loss)
       In June  1997,  the FASB  issued  SFAS No.  130,  "Reporting  Comprehensive
       Income."  This  statement,  which  establishes  standards for reporting and
       disclosure  of  comprehensive  income,  is effective for interim and annual
       periods beginning after December 15, 1997. The Company adopted SFAS No. 130
       effective January 1, 1998. Total  comprehensive  income (loss) for the nine
       and three  months  ended  September  30, 1998 and 1997 was $749.5  million,
       ($62.2)  million,  $760.0  million and $36.2 million,  respectively.  Total
       comprehensive  income (loss) includes net income (loss),  unrealized  gains
       (losses) on marketable  securities and foreign currency  translation  gains
       (losses) for the periods presented.
  
       Earnings (Loss) for Common Stockholders Per Common Share
       Earnings  (loss) for common  stockholders  per common  share is computed by
       dividing net income (loss),  after deduction of preferred stock  dividends,
       by the weighted  average  number of common  shares  outstanding  during the
       period on a basic and diluted basis.

  Put  options  sold by the  Company  on 2.75  million  shares of its Class A
       Special Common stock (see Note 6) were outstanding  during the three months
       ended  September  30,  1998 but were not  included  in the  computation  of
       Diluted EPS as the options' exercise price was less than the average market
       price of the Company's Class A Special Common Stock during the period.
  
       For the nine and three  months ended  September  30,  1997,  the  Company's
       potential common shares of 61.2 million shares have an antidilutive  effect
       on loss for common  stockholders  per  common  share for the  periods  and,
       therefore,  have not been used in determining  the total  weighted  average
       number of common shares outstanding.

  3.   SIGNIFICANT EVENTS
  
       Sale of Comcast UK Cable
       In February 1998, Comcast UK Cable Partners Limited ("Comcast UK Cable"), a
       consolidated subsidiary of the Company, entered into a definitive agreement
       to be acquired (the "NTL  Transaction")  by NTL  Incorporated  ("NTL"),  an
       alternative  telecommunications  company in the United Kingdom ("UK").  The
       Company received 4.8 million shares of NTL common stock in exchange for all
       of the shares of Comcast UK Cable held by the Company  upon  closing of the
       NTL Transaction on October 29, 1998.  Certain  conditions  agreed to in the
       NTL Transaction restrict the Company's ability to sell the NTL common stock
       to be  received  for a period  of 150 days  after  the  closing  of the NTL
       Transaction. The Company's investment in NTL common stock had a fair value,
       prior to  consideration  of the  restrictions  on the NTL common stock,  of
       approximately  $225.4  million,  based on the quoted market price of $46.75
       per share of NTL common stock as of October 29, 1998.  As of September  30,
       1998 and for the nine months then ended, the assets and revenues of Comcast
       UK Cable totaled $866.0 million and $93.7 million, respectively.

       AT&T Acquisition of TCGI
       In January  1998,  AT&T Corp.  ("AT&T")  entered into a  definitive  merger
       agreement with Teleport  Communications Group, Inc. ("TCGI").  Upon closing
       of the merger  (the  "AT&T  Transaction")  on July 23,  1998,  the  Company
       received 24.2 million shares of unregistered  AT&T common stock in exchange
       (the  "Exchange")  for the 25.6 million shares of TCGI Class B Common Stock
       held by the Company (see Note 4). As a result of the Exchange,  the Company
       recognized  a pre-tax  gain of  $1.092  billion  during  the nine and three
       months ended September 30, 1998,  representing  the difference  between the
       fair value of the AT&T stock received and the Company's basis in TCGI. Such
       gain  is  included  in  investment   income  in  the  Company's   condensed
       consolidated  statement of operations and accumulated  deficit. The Company
       has registration rights, subject to customary restrictions, which allow the
       Company  to  effect a  registration  of the  AT&T  shares  received.  As of
       September  30,  1998,  the Company has  recorded  its  investment  in AT&T,
       classified as available for sale, at its estimated fair value.
  
       Acquisition of Jones Intercable
       In May 1998,  the  Company  agreed to  purchase  from BCI  Telecom  Holding
       ("BTH") 6.4 million Class A Common Shares in Jones Intercable, Inc. ("Jones
       Intercable"),  and a 49%  interest  in the BTH  subsidiaries  which were to
       continue  to own BTH's  remaining  6.4 million  shares of Jones  Intercable
       Class A Common  Stock.  At the same  time,  the  Company  agreed to acquire
       approximately  2.9 million shares of Common Stock of Jones  Intercable (the
       "Control  Shares"),  if and when  acquired by BTH from  affiliates of Jones
       Intercable's controlling shareholder under an existing option (the "Control
       Option") to acquire such shares (which absent  extraordinary  circumstances
       would not have been  exercisable  until December 2001).  The Company was to
       purchase the remaining 51% of the BTH subsidiaries  when the Control Shares
       were acquired.  The Company,  BTH, Jones Intercable and Jones  Intercable's
       controlling  shareholder  agreed in August 1998 to  accelerate  the Control
       Option  to  permit  its  early  exercise  and  the  early  closing  of  the
       transactions  with BTH. At closing  (expected to occur in the first quarter
       of 1999,  subject to the receipt of  required  regulatory  approvals),  the
       Company  will pay BTH a total of $500  million in cash to acquire  the 12.8
       million shares of Jones Intercable Class A Common Stock and $200 million in
       cash to acquire the Control Shares. After closing, the Company will control
       approximately  37% of the economic and 47% of the voting  interest in Jones
       Intercable.  In addition,  the Control Shares will represent  shares having
       the right to elect  approximately  75% of the Board of  Directors  of Jones
       Intercable. The transaction will be funded either with new borrowings, with
       available  borrowings  under  existing  lines of credit or by other  means.
       Jones  Intercable,  a public  company,  owns or  manages  cable  operations
       serving approximately 1.0 million customers.

  Equity Method
       The Company records its proportionate interests in the net income (loss) of
       substantially  all of its  investees,  other  than  the UK  Investees  (see
       below), three months in arrears.  The Company holds interests  representing
       less than 20% of the total  outstanding  ownership  interests in certain of
       its equity  method  investees.  The equity method of accounting is utilized
       for  these  investments  based  on the  type of  investment  (e.g.  general
       partnership interest), board representation, participation in a controlling
       investor group,  significant  shareholder  rights or a combination of these
       and  other  factors.   The  Company's   recorded   investments  exceed  its
       proportionate  interests in the book value of the  investees' net assets by
       $141.2 million as of September 30, 1998 (primarily related to the Company's
       investments in The Golf Channel and Sprint PCS (see below)). Such excess is
       being amortized to equity in net income or loss, primarily over a period of
       twenty  years,  which  is  consistent  with  the  estimated  lives  of  the
       underlying assets. The

       (1) Net  loss  also  represents  loss  from  continuing  operations  before
           extraordinary  items and  cumulative  effect of changes  in  accounting
           principle.
       (2) As a result of the  acquisition of E!  Entertainment  Television,  Inc.
           ("E!  Entertainment")  on March 31, 1997, the Company recorded a charge
           representing  the  cumulative  amount that would have been recorded had
           the Company accounted for its investment in E! Entertainment  under the
           equity  method since the date of initial  investment  (the  "Cumulative
           Charge"). Since the Company's proportionate share of E! Entertainment's
           cumulative losses was in excess of the Company's  historical cost basis
           in E!  Entertainment  and as  the  Company  was  under  no  contractual
           obligation  to fund the  losses  of E!  Entertainment,  the  Cumulative
           Charge was  limited  to the  Company's  historical  cost basis of $12.1
           million.  Such amount is included in equity in net losses of affiliates
           in the Company's  condensed  consolidated  statement of operations  and
           accumulated  deficit for the nine months ended September 30, 1997 as it
           is  not  significant  for  restatement  of  the  Company's  prior  year
           financial statements.
  Sprint  PCS.   The  Company,   Tele-Communications,   Inc.   ("TCI"),   Cox
       Communications,  Inc.  ("Cox," and  together  with the Company and TCI, the
       "Cable Partners") and Sprint  Corporation  ("Sprint," and together with the
       Cable  Partners,  the  "Parents"),  engage in the  wireless  communications
       business through a limited  partnership  known as "Sprint PCS." The Company
       made its  initial  investment  in 1994 to  acquire  a general  and  limited
       partnership  interest of 15% in Sprint PCS. As of September  30, 1998,  the
       Company had contributed $669.5 million to Sprint PCS. No additional amounts
       are due with  respect to the  balance  of the  Company's  original  funding
       commitment to Sprint PCS.

          NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
                                     (Unaudited)
  
       In May  1998,  the  Parents  announced  an  agreement  (the  "Restructuring
       Agreement")  under which Sprint would assume total ownership and management
       control of Sprint PCS.
  
       At closing of the Restructuring Agreement, Sprint will issue a new class of
       Sprint stock (the "Sprint PCS Stock") to track the  performance of Sprint's
       combined wireless operations.  Initially,  in exchange for its interests in
       Sprint PCS, the Company will receive an  approximate  11.6% interest in the
       Sprint PCS Stock, consisting of approximately 47.2 million shares of Series
       2 Sprint PCS common stock,  approximately  2.2 million shares of Sprint PCS
       preferred  stock  (convertible  on  specified  terms to Series 2 Sprint PCS
       common stock) and warrants to purchase  approximately 3.0 million shares of
       Sprint PCS Stock. Under the Restructuring Agreement, Sprint will distribute
       its  interest  in the Sprint PCS Stock to its  existing  shareholders.  The
       Restructuring  Agreement  also  contemplates  a subsequent  initial  public
       offering ("IPO") of the Sprint PCS Stock. The Cable Partners'  interests in
       the Sprint  PCS Stock  would be  reduced  proportionately  by the amount of
       ownership  interests  issued in  connection  with an IPO, and in connection
       with any purchases made at that time by two of Sprint's major  shareholders
       under  existing   anti-dilution  rights  -  France  Telecom  S.A.  ("France
       Telecom") and Deutsche Telekom AG ("Deutsche Telekom").
  
       The Sprint PCS Stock will be divided  into three  categories:  (i) Series 1
       (one vote per share) to be held by the public, (ii) Series 2 (1/10 vote per
       share  other  than in class  votes) to be held by the Cable  Partners,  and
       (iii)  Series 3 (one  vote per  share)  to be held by  France  Telecom  and
       Deutsche Telekom. Under the terms of the Restructuring Agreement, the Cable
       Partners have registration rights, subject to customary restrictions, that,
       if used, would permit the monetization of their Sprint PCS holdings through
       equity offerings or derivatives.  If the Series 2 shares are transferred by
       a Cable Partner, the transferred shares become full vote Series 1 shares.
  
       On September 25, 1998, Sprint Corporation filed a preliminary  registration
       statement  with the  Securities  and  Exchange  Commission  (the  "SEC") to
       register up to $604.0 million in an IPO of its Sprint PCS Stock. The timing
       of the public offering can not yet be determined.
  
       On November 13, 1998, the Sprint  stockholders  approved the  Restructuring
       Agreement. The Restructuring Agreement is expected to close on November 23,
       1998, subject to the receipt of necessary regulatory approvals.
  
       TCGI. In April 1998, in connection  with an  acquisition,  TCGI issued 16.3
       million  shares of its Class A Common  Stock (the "TCGI  Acquisition").  In
       November 1997, TCGI filed a registration statement with the SEC to sell 7.3
       million  shares of TCGI Class A Common  Stock (the "TCGI  Offering").  As a
       result  of  the  TCGI  Acquisition  and  the  TCGI  Offering,  the  Company
       recognized a $157.8 million and $98.2 million increase in its proportionate
       share of TCGI's net assets as a gain from equity  offering of affiliate for
       the nine and three  months ended  September  30,  1998,  respectively.  The
       Company records its proportionate share of TCGI's net assets one quarter in
       arrears.
  
       UK Investees. As of September 30, 1998, Comcast UK Cable (see Note 3) holds
       a 27.5%  interest  in  Birmingham  Cable  Corporation  Limited  and a 50.0%
       interest in Cable London PLC.
  
       Comcast-Spectacor.  Effective  January 1,  1998,  the  Company's  condensed
       consolidated   financial   statements   include  the  accounts  of  Comcast
       Spectacor,  L.P.  ("Comcast-Spectacor"),  an affiliate previously accounted
       for under the equity method, due to certain call rights held by the Company
       which became exercisable effective January 16, 1998.
  
       Other.  The Company's other equity investees  include  investments in cable
       communications   (including   Garden  State   Cablevision   L.P.,  a  cable
       communications   company  serving  more  than  210,000  subscribers  as  of
       September   30,   1998  in  the   State   of  New   Jersey),   cellular/PCS
       telecommunications  and content  providers.  The Company  does not consider
       these other equity method investments to be individually significant to its
       consolidated financial position, results of operations or liquidity.
  
       Fair Value Method
       The Company  holds  unrestricted  equity  investments  in certain  publicly
       traded  companies,  with an  historical  cost  (including a $1.092  billion
       pre-tax gain  recognized  during the third quarter of 1998 - see Note 3) of
       $1.466 billion and $130.0 million as of September 30, 1998 and December 31,
       1997, respectively.  The Company has recorded these investments,  which are
       classified as available for sale, at their  estimated fair values of $1.985
       billion and

       $346.5   million  as  of   September   30,  1998  and  December  31,  1997,
       respectively.  The  unrealized  pre-tax  gains as of September 30, 1998 and
       December 31, 1997 of $518.9 million and $216.5 million, respectively,  have
       been reported in the Company's  condensed  consolidated  balance sheet as a
       component  of  stockholders'  equity,  net of related  deferred  income tax
       expense of $181.6 million and $75.8 million, respectively.
  
       In March 1998, the Company sold call options  relating to its  unrestricted
       equity investments in TCI, TCI Ventures Group, Inc. and Liberty Media Group
       common  stock  (together,  the "TCI  Stock") for $20.7  million.  Such call
       options expire between March and September 1999.  During the nine and three
       months ended September 30, 1998, the Company  recorded  pre-tax  investment
       (expense) income of ($32.1) million and $8.1 million, respectively, related
       to changes in the value of the call options.
  
       During the nine and three months  ended  September  30,  1998,  the Company
       recorded a pre-tax  loss of $91.2  million  on  certain of its  investments
       based on a decline in value that is considered  other than temporary.  Such
       pre-tax loss is recorded in investment  income in the  Company's  condensed
       consolidated statement of operations and accumulated deficit.
  
  5.   LONG-TERM DEBT
  
       Debt Offering
       On November 10, 1998,  the  Company,  through its wholly owned  subsidiary,
       Comcast Cable Communications,  Inc. ("Comcast Cable") announced that it has
       sold $800.0 million  aggregate  principal  amount of 6.20% senior notes due
       2008 in a public offering (the  "Offering").  Interest on the notes will be
       payable semiannually on May 15 and November 15 of each year, commencing May
       15, 1999. The notes are redeemable only upon maturity on November 15, 2008.
       The Company  expects to use all of the net  proceeds  from the Offering for
       general corporate  purposes.  The Offering is expected to close on November
       16, 1998.
  
       Redemption of 1 1/8% Debentures
       In March 1998,  the Company  completed the redemption of its $541.9 million
       principal amount 1 1/8% discount  convertible  subordinated  debentures due
       2007 (the "1 1/8%  Debentures").  The Company issued 10.4 million shares of
       its  Class A  Special  Common  Stock  upon  conversion  of  $540.2  million
       principal amount of 1 1/8% Debentures  while $1.7 million  principal amount
       of 1 1/8% Debentures was redeemed for cash at a redemption price of 67.112%
       of  the  principal   amount,   together  with  accrued  interest   thereon.
       Stockholders'  equity was increased by the full amount of 1 1/8% Debentures
       converted plus accrued interest,  less unamortized debt acquisition  costs.
       Unamortized  debt  acquisition  costs  related  to  the 1  1/8%  Debentures
       redeemed for cash were not significant. The issuance of the Company's Class
       A Special  Common Stock upon  conversion  of the 1 1/8%  Debentures  had no
       impact on the Company's condensed  consolidated statement of cash flows due
       to its noncash nature.
  
       Interest Rates
       As of September  30, 1998 and December 31, 1997,  the  Company's  effective
       weighted  average interest rate on its long-term debt outstanding was 8.39%
       and 8.36%, respectively.
  
       Lines of Credit
       As of  November  2, 1998,  certain  subsidiaries  of the Company had unused
       lines of credit of $870.5 million, $370.5 million of which is restricted by
       the  covenants of the related debt  agreements  and to  subsidiary  general
       purposes and dividend declaration.
  
  6.   STOCKHOLDERS' EQUITY
  
       Repurchase Program
       In September  1998,  the Company  announced that its Board of Directors had
       authorized a market repurchase program (the "Repurchase  Program") pursuant
       to which  the  Company  may  purchase,  in the open  market  or in  private
       transactions  up  to  $500.0  million  of  its  outstanding  common  equity
       securities,  subject to certain restrictions and market conditions. Through
       September 30, 1998, the Company had repurchased  shares of its common stock
       for  aggregate  consideration  of $9.5 million  pursuant to the  Repurchase
       Program.  Through October 31, 1998, the

                                     (Unaudited)
  
       Company had repurchased  additional  shares for aggregate  consideration of
       $3.4 million.  In  conjunction  with the Repurchase  Program,  in September
       1998,  the Company sold put options on 2.75  million  shares of its Class A
       Special Common Stock.  The put options give the holder the right to require
       the Company to repurchase such shares at specified prices on specific dates
       during the period  from April  through  September  1999.  Proceeds of $11.4
       million  from the sale of these put options  were  credited  to  additional
       capital.  The amount the Company  would be obligated  to pay to  repurchase
       such shares if all outstanding put options were exercised,  totaling $111.2
       million,  has  been  reclassified  to a  temporary  equity  account  in the
       Company's condensed consolidated balance sheet as of September 30, 1998.
  
       In April 1997, in connection with the Company's  previous market repurchase
       program which  terminated in May 1997,  the Company sold put options on 2.0
       million shares of its Class A Special Common Stock. The put options,  which
       expired unexercised during April and May 1998, gave the holder the right to
       require the  Company to  repurchase  such  shares at a  specified  price on
       specific  dates  in  April  and May  1998.  Upon  expiration,  the  Company
       reclassified $31.4 million,  the amount it would have been obligated to pay
       to repurchase such shares had the put options been  exercised,  from common
       equity  put  options  to  additional  capital  in the  Company's  condensed
       consolidated balance sheet.
  
  7.   STATEMENT OF CASH FLOWS - SUPPLEMENTAL INFORMATION
  
       The Company  made cash  payments  for  interest of $334.1  million,  $303.4
       million,  $71.5 million and $69.6 million  during the nine and three months
       ended September 30, 1998 and 1997, respectively.
  
       The Company made cash  payments for income taxes of $105.2  million,  $89.7
       million,  $17.1 million and $14.7 million  during the nine and three months
       ended September 30, 1998 and 1997, respectively.
  
       During the three months ended  September 30, 1998, the Company  settled all
       issues  primarily  related to the  deductibility  of  amortization of cable
       television  distribution  rights  raised by the  Internal  Revenue  Service
       ("IRS")  in its  examination  of QVC,  Inc.,  a majority  owned  subsidiary
       ("QVC"),  through  fiscal  tax year 1993.  Such  settlement  resulted  in a
       reversal of previously recorded deferred tax liabilities of $135.5 million.
       As a result of the settlement, the Company recorded an adjustment to reduce
       goodwill by $119.7  million  during the three  months ended  September  30,
       1998.  Such  adjustment  has been  excluded  from the  Company's  condensed

  ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
            RESULTS OF OPERATIONS
  
  Overview
  
  The Company has  experienced  significant  growth in recent  years both  through
  strategic  acquisitions and growth in its existing  businesses.  The Company has
  historically  met its cash  needs for  operations  through  its cash  flows from
  operating   activities.   Cash   requirements   for   acquisitions  and  capital
  expenditures have been provided through the Company's  financing  activities and
  sales of long-term  investments,  as well as its existing cash, cash equivalents
  and short-term investments.
  
  General Developments of Business
  
  See Note 3 to the Company's condensed consolidated financial statements included
  in Item 1.
  
  Liquidity and Capital Resources
  
  Cash, Cash Equivalents,  Short-term  Investments and Investments,  Available for
  Sale The Company has traditionally  maintained  significant levels of cash, cash
  equivalents,  short-term investments and investments, available for sale to meet
  its  short-term  liquidity  requirements.  Cash,  cash  equivalents,  short-term
  investments  and  investments,  available for sale as of September 30, 1998 were
  $2.138 billion.  As of September 30, 1998, $406.1 million of the Company's cash,
  cash equivalents,  short-term investments and investments, available for sale is
  restricted  to use by  subsidiaries  of the Company under  contractual  or other
  arrangements,  including $146.8 million which is restricted to use by Comcast UK
  Cable Partners Limited  ("Comcast UK Cable"),  a consolidated  subsidiary of the
  Company  (see  Note  3  to  the  Company's  condensed   consolidated   financial
  statements).
  
  The Company's cash  equivalents and short-term  investments are recorded at cost
  which  approximates  their fair value.  As of  September  30,  1998,  short-term
  investments have a weighted average maturity of approximately  five months.  The
  Company's investments, available for sale are recorded at fair value.
  
  Investments
  See Notes 3 and 4 to the Company's condensed  consolidated  financial statements
  included in Item 1.
  
  The Company does not have any significant  contractual  commitments with respect
  to any of its investments.  However, to the extent the Company does not fund its
  investees'  capital  calls,  it  exposes  itself to  dilution  of its  ownership
  interests. The Company continually evaluates its existing investments as well as
  new investment opportunities.
  
  Financing
  See Notes 5 and 6 to the Company's condensed  consolidated  financial statements
  included in Item 1.
  
  As of September 30, 1998 and December 31, 1997,  the Company's  long-term  debt,
  including current portion, was $6.704 billion and $6.691 billion,  respectively,
  of which 22.1% and 17.1%, respectively, was at variable rates.
  
  The Company may from time to time, depending on certain factors including market
  conditions, make optional repayments on its debt obligations,  which may include
  open market repurchases of its outstanding public notes and debentures.
  
  Year 2000 Issue
  
  The Year 2000 Issue is the result of computer  programs  being written using two
  digits rather than four to define the applicable year.  Certain of the Company's
  computer programs that have  date-sensitive  software may recognize a date using
  "00" as the year 1900 rather than the year 2000 (the "Year 2000 Issue"). If this
  situation   occurs,   the  potential  exists  for  computer  system  failure  or
  miscalculations   by  computer   programs,   which  could  cause  disruption  of
  operations.

                          QUARTER ENDED SEPTEMBER 30, 1998
  
  The Company is in the process of  evaluating  and  addressing  the impact of the
  Year 2000 Issue on its operations to ensure that its information  technology and
  business  systems  recognize  calendar Year 2000.  The Company is utilizing both
  internal and external  resources in  implementing  its Year 2000 program,  which
  consists of the following phases:
  
  Assessment Phase
  Structured evaluation,  including a detailed inventory outlining the impact that
  the Year 2000 Issue may have on current operations.
  
  Detailed Planning Phase
  Establishment of priorities, development of specific action steps and allocation
  of resources to address the issues identified in the Assessment Phase.
  
  Conversion Phase
  Implementation of the necessary system modifications as outlined in the Detailed
  Planning Phase.
  
  Testing Phase
  Verification that the modifications  implemented in the Conversion Phase will be
  successful  in resolving  the Year 2000 Issue so that all  inventory  items will
  function properly, both individually and on an integrated basis.
  
  Implementation Phase
  Final roll-out of fully tested components into an operational unit.
  
  Based on an inventory  conducted in 1997,  the Company has  identified  computer
  systems that will require modification or replacement so that they will properly
  utilize dates beyond December 31, 1999. Many of the Company's  critical  systems
  are new and are already Year 2000 compliant as a result of the recent rebuild of
  many of the Company's cable  communications  systems and the implementation of a
  fully digital  cellular  communications  network.  In addition,  the Company has
  initiated  communications  with all of its  significant  software  suppliers and
  service  bureaus to determine their plans for remediating the Year 2000 Issue in
  their software which the Company uses or relies upon.
  
  As of September  30, 1998,  the Company is in the  Conversion  Phase of its Year
  2000  remediation  program and has entered  the  Testing  Phase with  respect to
  certain of its key systems. Through September 30, 1998, the Company has incurred
  approximately $5.0 million in connection with its Year 2000 remediation program.
  The Company  estimates that it will incur between  approximately  $10 million to
  $20 million of additional  expense through  December 1999 in connection with its
  Year  2000  remediation   program.   The  Company's  estimate  to  complete  the
  remediation plan includes the estimated time associated with mitigating the Year
  2000 Issue for third party software. However, there can be no guarantee that the
  systems of other  companies  on which the Company  relies will be converted on a
  timely basis,  or that a failure to convert by another  company would not have a
  material adverse effect on the Company.
  
  Management of the Company will continue to  periodically  report the progress of
  its Year 2000 remediation  program to the Audit Committee of the Company's Board
  of  Directors.  The Company  plans to complete the Year 2000  mitigation  by the
  third  quarter of 1999.  Management  of the  Company  has  investigated  and may
  consider  potential  contingency plans in the event that the Company's Year 2000
  remediation program is not completed by that date.
  
  The costs of the project and the date on which the Company plans to complete the
  Year  2000  modifications  and  replacements  are  based  on  management's  best
  estimates,  which were derived using  assumptions of future events including the
  continued   availability  of  resources  and  the  reliability  of  third  party
  modification plans. However, there can be no guarantee that these estimates will
  be  achieved  and actual  results  could  differ  materially  from those  plans.
  Specific factors that may cause such material  differences  include, but are not
  limited to, the availability  and cost of personnel with  appropriate  necessary
  skills and the  ability to locate and  correct all  relevant  computer  code and
  similar uncertainties.
  
  The  Company  believes  that  with   modifications  to  existing   software  and
  conversions to new software,  the Year 2000 Issue can be mitigated.  However, if
  such  modifications and conversions are not made, or are not completed within an
  adequate time frame, the Year 2000 Issue could have a material adverse impact on
  the operations of the Company.
                              -------------------------

  The telecommunications  industry,  including cable and cellular  communications,
  and the electronic  retailing industry are experiencing  increasing  competition
  and rapid technological changes. The Company's future results of operations will
  be affected by its  ability to react to changes in the  competitive  environment
  and by its ability to implement new technologies.  However, the Company believes
  that competition,  technological  changes and its history of significant  losses
  will not significantly affect its ability to obtain financing.
  
  The Company  believes  that it will be able to meet its  current  and  long-term
  liquidity and capital  requirements,  including fixed charges,  through its cash
  flows from operating  activities,  existing cash, cash  equivalents,  short-term
  investments,  investments,  available  for sale and  lines of  credit  and other
  external financing.
  
  Statement of Cash Flows
  
  Cash and cash equivalents  increased $21.3 million as of September 30, 1998 from
  December 31, 1997 and  increased  $242.3  million as of September  30, 1997 from
  December 31, 1996.  Increases in cash and cash  equivalents  resulted  from cash
  flows from  operating,  financing and investing  activities  which are explained
  below.
  
  Net cash provided by operating  activities amounted to $818.6 million and $742.1
  million for the nine months ended September 30, 1998 and 1997, respectively. The
  increase of $76.5  million is  principally  due to the increase in the Company's
  operating  income  before   depreciation  and  amortization   (see  "Results  of
  Operations")  and  changes  in  working  capital  as a result  of the  timing of
  receipts  and  disbursements,  including  the  effects of the  consolidation  of
  Comcast  Spectacor,  L.P.  ("Comcast-Spectacor")  effective January 1, 1998 (see
  Note 4 to the Company's condensed  consolidated financial statements included in
  Item  1)  and  the  acquisition  of  E!  Entertainment  Television,   Inc.  ("E!
  Entertainment") on March 31, 1997 (the "E! Acquisition").
  
  Net cash provided by financing  activities was $134.2 million and $345.3 million
  for the nine months ended September 30, 1998 and 1997, respectively.  During the
  nine months ended  September 30, 1998, the Company  borrowed  $1.058 billion and
  repaid $922.5 million of its long-term  debt,  primarily in connection  with the
  refinancing  of certain  subsidiary  indebtedness  in March 1998.  In  addition,
  during the nine months ended  September 30, 1998,  the Company had net issuances
  of $23.8 million of its common stock and paid cash dividends of $27.1 million on
  its common  stock and Series A Preferred  Stock.  During the nine  months  ended
  September 30, 1997, the Company borrowed $2.968 billion, primarily in connection
  with the refinancing of certain  subsidiary  indebtedness and the acquisition of
  E!  Entertainment  (the "E!  Acquisition"),  and  repaid  $3.518  billion of its
  long-term  debt,  primarily  in  connection  with  the  refinancing  of  certain
  subsidiary  indebtedness and the redemption of debt. Deferred financing costs of
  $43.8  million were  incurred  during the nine months ended  September  30, 1997
  related to the issuance of certain subsidiary senior notes. In addition,  during
  the nine months ended September 30, 1997, the Company received $1.0 billion from
  Microsoft  Corporation  for the issuance of its Class A Special Common Stock and
  Series B Preferred Stock, repurchased $36.0 million of its common stock and paid
  cash  dividends  of $25.2  million  on its common  stock and Series A  Preferred
  Stock.
  
  Net cash used in investing  activities was $931.5 million and $845.1 million for
  the nine months ended September 30, 1998 and 1997, respectively. During the nine
  months ended September 30, 1998, net cash used in investing  activities includes
  acquisitions, net of cash acquired, of $269.4 million, investments in affiliates
  of $137.6 million and capital expenditures of $684.8 million, offset by proceeds
  from the sales of short-term  investments and call options of $145.9 million and
  proceeds  from the repayment of a loan by an investee of $74.7  million.  During
  the nine months ended September 30, 1997, net cash used in investing  activities
  includes acquisitions,  net of cash acquired, of $136.1 million,  investments in
  affiliates of $180.3 million and capital expenditures of $682.0 million,  offset
  by the proceeds from the sales of short-term  and  long-term  investments  and a
  distribution  from an investee of $171.5 million and proceeds from the repayment
  of a loan by an investee of $25.2 million.
  
  Results of Operations
  
  The  effects of the  Company's  recent  acquisitions  and the  consolidation  of
  Comcast-Spectacor  effective  January 1, 1998,  as well as  increased  levels of
  capital  expenditures,  were to increase  the  Company's  revenues  and expenses
  resulting  in  increases  in  its  operating  income  before   depreciation  and
  amortization,  depreciation expense,  amortization expense and interest expense.
  In addition,  the  Company's  equity in net losses of  affiliates  has increased
  principally  as a result of the  start-up  nature of  certain  of the  Company's
  equity investees (see "Consolidated Analysis").

  (1)  Operating income before  depreciation and amortization is commonly referred
       to in the Company's  businesses as "operating  cash flow."  Operating  cash
       flow is a measure of a company's  ability to  generate  cash to service its
       obligations, including debt service obligations, and to finance capital and
       other  expenditures.  In part due to the  capital  intensive  nature of the
       Company's  businesses  and the  resulting  significant  level  of  non-cash
       depreciation  expense  and  amortization  expense,  operating  cash flow is
       frequently  used  as one of  the  bases  for  comparing  businesses  in the
       Company's industries, although the Company's measure of operating cash flow
       may not be  comparable  to similarly  titled  measures of other  companies.
       Operating  cash flow does not purport to  represent  net income or net cash
       provided  by  operating  activities,  as  those  terms  are  defined  under
       generally accepted accounting

  The  respective  increases in net sales of $210.5  million and $83.3 million for
  the nine and three  month  periods  from 1997 to 1998 are due to the  effects of
  6.2% and 4.3% increases in the average number of homes receiving QVC services in
  the United  States  ("US"),  increases in net sales per home and 12.5% and 11.0%
  increases in the average  number of homes  receiving  QVC services in the United
  Kingdom.
  
  The increases in cost of goods sold are  primarily  related to the growth in net
  sales.
  
  Of the $22.1 million increase in operating,  selling, general and administrative
  expenses  for the  nine  month  period  from  1997 to  1998,  $21.4  million  is
  attributable  to higher  variable  costs  associated  with the increase in sales
  volume. The remaining increase is attributable to personnel and facilities based
  costs   associated  with  Studio  Park,   QVC's  new   production,   studio  and
  administrative  facility  which  was  opened in the  third  quarter  of 1997 and
  expansion in the UK and Germany,  partially  offset by savings in marketing  and
  promotional costs in the US. Of the $8.7 million increase in operating, selling,
  general and  administrative  expenses  for the three  month  period from 1997 to
  1998, $8.9 million is attributable to higher variable costs  associated with the
  increase in sales volume.  The remaining  decrease is primarily  attributable to
  reduced marketing and promotional costs in the US.

  Service income increased by $2.6 million and $1.6 million for the nine and three
  month periods from 1997 to 1998, as  subscriber  growth was offset,  in part, by
  the effects of increased  use of  promotional  and free minute plans  offered to
  subscribers.  These plans  generally  have higher  access fees and  increase the
  minutes of use per subscriber while lowering the average rate per minute of use.
  
  The respective  $6.5 million and $5.6 million  increases in operating,  selling,
  general and  administrative  expenses for the nine and three month  periods from
  1997 to  1998  are  primarily  the  result  of  increases  in  commission  costs
  associated with more gross sales in 1998.
  
  Consolidated Analysis
  
  The respective $65.6 million and $18.3 million increases in depreciation expense
  for  the  nine  and  three  month  periods  from  1997  to  1998  are  primarily
  attributable to the effects of capital  expenditures,  increased losses on asset
  disposals in connection with the Company's domestic cable communications rebuild
  activities, the consolidation of Comcast- Spectacor and the acquisition of cable
  communications systems.
  
  The respective $28.1 million and $11.4 million increases in amortization expense
  for  the  nine  and  three  month  periods  from  1997  to  1998  are  primarily
  attributable to the effects of the consolidation of Comcast-Spectacor.
  
  The $14.5  million  increase in interest  expense for the nine month period from
  1997 to 1998 is attributable to the effects of capitalized  interest  associated
  with the  Company's  investment  in Sprint  PCS  during  the nine  months  ended
  September 30, 1997, the consolidation of  Comcast-Spectacor,  the E! Acquisition
  and an increase in the  Company's  effective  weighted  average  interest  rate,
  offset,  in part, by lower levels of debt outstanding.  The Company  anticipates
  that, for the foreseeable future, interest expense will be a significant cost to
  the Company and will have a significant  adverse effect on the Company's ability
  to realize net  earnings.  The Company  believes it will  continue to be able to
  meet its  obligations  through its ability  both to  generate  operating  income
  before depreciation and amortization and to obtain external financing.
  
  In January 1998, AT&T Corp.  ("AT&T") entered into a definitive merger agreement
  with Teleport  Communications Group Inc. ("TCGI"). Upon closing of the merger on
  July 23, 1998,  the Company  received 24.2 million shares of  unregistered  AT&T
  common stock in exchange (the  "Exchange") for 25.6 million shares of TCGI Class
  B common stock held by the  Company.  As a result of the  Exchange,  the Company
  recognized a pre-tax gain of $1.092 billion during the

  nine and three months ended  September  30, 1998,  representing  the  difference
  between the fair value of the AT&T stock  received  and the  Company's  basis in
  TCGI.  Such gain is included in  investment  income in the  Company's  condensed
  consolidated statement of operations and accumulated deficit.
  
  During the nine and three months ended September 30, 1998, the Company  recorded
  a pre-tax loss of $91.2 million on certain of its investments based on a decline
  in value that is considered other than temporary.  Such pre-tax loss is included
  in  investment  income in the  Company's  condensed  consolidated  statement  of
  operations and accumulated deficit.
  
  In March 1998, the Company sold call options relating to its unrestricted equity
  investments in  Tele-Communications,  Inc. ("TCI"), TCI Ventures Group, Inc. and
  Liberty Media Group common stock (together,  the "TCI Stock") for $20.7 million.
  Such call options expire between March and September  1999.  During the nine and
  three months ended September 30, 1998, the Company recorded  pre-tax  investment
  (expense) income of ($32.1) million and $8.1 million,  respectively,  related to
  changes in the value of the call options. In addition, as of September 30, 1998,
  the Company  recorded net unrealized  gains (losses) of $47.9 million and ($5.2)
  million related to the TCI Stock,  net of deferred income tax expense  (benefit)
  of $25.8  million and ($2.8)  million,  to its  condensed  consolidated  balance
  sheet,  representing the increase in fair value of the TCI Stock during the nine
  and three months ended September 30, 1998, respectively.
  
  During the first  quarter of 1997 the Company  received  2.76 million  shares of
  TCGI  Class A Stock  from  TCGI in  exchange  for  the  Company's  shares  of an
  alternate  access  provider.  In May 1997, the Company sold all of its shares of
  TCGI Class A Stock for $68.9  million  and  recognized  a pre-tax  gain of $68.9
  million.  In February  1997,  the Company  sold  options to acquire 25.0 million
  shares of Nextel  Communications,  Inc.  ("Nextel")  common  stock to Nextel for
  $25.0 million and  recognized a pre-tax gain of $5.0  million.  In January 1997,
  the Company sold 1.27 million shares of Time Warner, Inc. ("Time Warner") common
  stock,  representing  the Company's  entire  interest in Time Warner,  for $48.6
  million and  recognized a pre-tax loss of $3.8  million.  Such pre-tax gains and
  pre-tax  loss are  included  in  investment  income in the  Company's  condensed
  consolidated statement of operations and accumulated deficit.
  
  The  $128.2  million  and $22.4  million  increases  in equity in net  losses of
  affiliates  for the nine and three month periods from 1997 to 1998 are primarily
  due to the effects of increased losses incurred by Sprint PCS (see Note 4 to the
  Company's condensed consolidated financial statements included in Item 1).
  
  In April 1998,  in  connection  with an  acquisition,  TCGI issued 16.3  million
  shares of its Class A Common Stock (the "TCGI  Acquisition").  In November 1997,
  TCGI filed a registration  statement with the Securities and Exchange Commission
  to sell 7.3  million  shares of TCGI Class A Stock (the "TCGI  Offering").  As a
  result of the TCGI Acquisition and the TCGI Offering,  the Company  recognized a
  $157.8 million and $98.2 million increase in its  proportionate  share of TCGI's
  net assets as a gain from equity  offering of  affiliate  for the nine and three
  months  ended  September  30,  1998,  respectively.   The  Company  records  its
  proportionate share of TCGI's net losses one quarter in arrears.
  
  The  fluctuations in other (income) expense for the nine and three month periods
  from 1997 to 1998 are primarily  attributable  to the effects of fluctuations in
  the foreign currency exchange rate.
  
  The $263.9  million and $300.5  million  increases in income tax expense for the
  nine and three month  periods from 1997 to 1998 are  primarily the result of the
  effects of changes in the Company's  income before taxes and minority  interest,
  and  non-deductible  foreign losses and  non-deductible  equity in net losses of
  affiliates.
  
  The $22.5 million and $21.9 million  decreases in minority interest for the nine
  and three month  periods  from 1997 to 1998 are  primarily  attributable  to the
  effects of changes in the net  income  (loss) of QVC and  Comcast UK Cable,  the
  consolidation of Comcast-Spectacor and the E! Acquisition.
  
  In connection with the redemption of certain indebtedness,  the Company expensed
  unamortized debt  acquisition  costs and incurred debt  extinguishment  costs of
  $4.7 million, resulting in an extraordinary loss, net of tax, of $3.0 million or
  $0.01 per common  share during the nine and three  months  ended  September  30,
  1998. In connection with the refinancing of certain  subsidiaries'  indebtedness
  and the redemption of debt, the Company  expensed  unamortized  debt acquisition
  costs and incurred debt extinguishment  costs of $39.8 million and $4.7 million,
  resulting in an  extraordinary  loss,  net

  of tax, of $25.9  million or $.08 per common  share and $3.1 million or $.01 per
  common  share  during  the nine and  three  months  ended  September  30,  1997,
  respectively.  For the nine and three months ended  September 30, 1998 and 1997,
  the Company's  earnings  (net income  (loss) plus income tax expense  (benefit),
  equity  in net  losses of  affiliates,  fixed  charges  (interest  expense)  and
  extraordinary  items) were $1.645 billion,  $555.7  million,  $1.280 billion and
  $186.2 million, respectively. Such earnings were adequate to cover the Company's
  fixed  charges  (including  interest  capitalized  of $18.0 million for the nine
  months ended  September  30, 1997) of $437.3  million,  $440.8  million,  $145.4
  million and $143.9  million for the nine and three  months ended  September  30,
  1998 and 1997,  respectively.  Fixed charges include non-cash  interest expense,
  net of interest capitalized,  of $37.4 million, $42.7 million, $11.3 million and
  $13.8  million for the nine and three months ended  September 30, 1998 and 1997,
  respectively.
  
  The  Company  believes  that  its  losses  will  not  significantly  affect  the
  performance of its normal business activities because of its existing cash, cash
  equivalents,  short-term  investments and  investments,  available for sale, its
  ability to generate  operating  income before  depreciation and amortization and
  its ability to obtain external financing.
  
  The  Company  believes  that  its  operations  are not  materially  affected  by
  inflation.
