                            ------------------------

    You should understand the following when reading the combined financial
statements of the MCI group, which is an integrated business of WorldCom, Inc.:

    - WorldCom has presented the combined financial statements of the MCI group
      at substantially the same level of detail as the consolidated financial
      statements of WorldCom. WorldCom believes that investors will require
      detailed financial information for the MCI group to properly evaluate the
      market potential of MCI group stock.

    - the MCI group is a collection of WorldCom's MCI businesses and is not a
      separate legal entity;

    - the holders of the MCI group stock are shareholders of WorldCom and do not
      have an ownership interest in the MCI group or any company in the MCI
      group or a claim on any of the assets attributed to the MCI group;

    - the attribution of a portion of WorldCom's assets and liabilities to the
      MCI group does not affect WorldCom's ownership of these assets or
      responsibility for these liabilities and does not affect the rights of any
      creditor of WorldCom; and

    - the assets attributed to the MCI group could be subject to the liabilities
      attributed to the WorldCom group.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders of WorldCom, Inc.:

    We have audited the accompanying combined balance sheets of MCI group (an
integrated business of WorldCom, Inc.) (as described in Note 1) as of
December 31, 1999 and 2000, and the related combined statements of operations,
allocated net worth and cash flows for each of the years in the two-year period
ended December 31, 2000. These financial statements are the responsibility of
WorldCom, Inc.'s management. Our responsibility is to express an opinion on
these financial statements based on our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the MCI group combined financial statements referred to
above present fairly, in all material respects, the combined financial position
of MCI group as of December 31, 1999 and 2000, and the combined results of its
operations and its cash flows for each of the years in the two-year period ended
December 31, 2000, in conformity with accounting principles generally accepted
in the United States.

    As discussed in Note 1 to the combined financial statements, effective
January 1, 2000, MCI group changed its method of accounting for certain
activation and installation fee revenues and expenses. Additionally, effective
January 1, 1998, MCI group changed its method of accounting for start-up
activities.

    MCI group is a fully integrated business of WorldCom, Inc. Accordingly, as
described in Note 1, the MCI group's combined financial statements have been
derived from the consolidated financial statements and accounting records of
WorldCom, Inc. and, therefore, reflect certain assumptions and allocations. As
more fully discussed in Note 1, the combined financial statements of MCI group
should be read in conjunction with the audited consolidated statements of
WorldCom, Inc.

    The financial statements of MCI group as of and for the year ended
December 31, 1998, were not audited by us and, accordingly, we do not express an
opinion on them.

                               DECEMBER 31, 2000

(1)  THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES--

DESCRIPTION OF BUSINESS AND ORGANIZATION:

    Organized in 1983, WorldCom, Inc., a Georgia corporation (the "Company")
provides a broad range of communications services to both U.S. and non-U.S.
based businesses and consumers. The Company is a global communications company
utilizing an "on-net" strategy based on being able to provide service through
its own facilities throughout the world instead of being restricted to a
particular geographic location. The on-net approach allows the Company's
customers to send data or voice communications across town, across the U.S., or
to any of our networks in Europe or Asia, without ever leaving the Company's
networks. The on-net approach provides the Company's customers with superior
reliability and low operating costs. Prior to May 1, 2000, the Company was named
MCI WORLDCOM, Inc.

    The Company's core business is communications services, which includes
voice, data, Internet and international services. The Company serves as a
holding company for its subsidiaries' operations. References herein to the
Company include the Company and its subsidiaries, unless the context otherwise
requires.

BASIS OF COMBINATION AND PRESENTATION:

    On November 1, 2000, the Company announced a realignment of its businesses
with the distinct customer bases they serve. While WorldCom, Inc. will remain
the name of the company, it will create two separately traded tracking stocks:

    - WorldCom group stock ("WorldCom stock") is intended to reflect the
      performance of the Company's data, Internet, international and commercial
      voice businesses and is expected to be quoted on The Nasdaq National
      Market under the trading symbol "WCOM", and

    - MCI group stock ("MCI stock") is intended to reflect the performance of
      the Company's consumer, small business, wholesale long distance, wireless
      messaging and dial-up Internet access businesses and is expected to be
      quoted on The Nasdaq National Market under the trading symbol "MCIT".

    A tracking stock is a separate class of a company's common stock intended to
provide a return to investors based upon the financial performance of a distinct
business unit of the company, sometimes referred to as the targeted business.
These targeted businesses are collections of businesses that the Company has
grouped together in order for the Company to issue WorldCom group stock and MCI
group stock. The ownership of the targeted business does not change, and while
each of the classes of stock trade separately, all shareholders are common
shareholders of a single company, WorldCom, Inc., and will be subject to all
risks of an investment in the Company as a whole.

    Under the plan, which must be approved by the Company's shareholders, the
Company will amend its articles of incorporation to effect a recapitalization
that will replace the Company's existing common stock with two new series of
Company common stock that are intended to reflect, or track, the performance of
the businesses attributed to WorldCom group and MCI group. The Company expects
to hold its shareholder meeting to vote on the recapitalization in the first
half of 2001, and to effect the recapitalization shortly after the Company
receives the necessary shareholder approval. No regulatory approvals are
expected to be required.

                               DECEMBER 31, 2000

(1)  THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES-- (CONTINUED)
    If the Company's shareholders approve the recapitalization, each share of
the Company's existing common stock will be changed into one share of WorldCom
stock and 1/25 of a share of MCI stock. After the recapitalization, a common
shareholder's ownership in WorldCom, Inc. will then be represented by two
stocks: WorldCom stock and MCI stock.

    All assets reported in the accompanying combined financial statements are
owned by the Company or one of its subsidiaries. These combined financial
statements are based on the operations, attributed assets and attributed
liabilities of MCI group and are not representative of any separately
incorporated entity.

    The MCI group combined financial statements will provide MCI group
shareholders with financial information about MCI group's operations. Investors
in MCI stock and WorldCom stock will be shareholders of the Company and will be
subject to risks related to all of the Company's businesses, assets and
liabilities. The Company retains ownership and control of the attributed assets,
attributed liabilities and operations of MCI group and WorldCom group. Financial
effects of either group that affect the Company's consolidated results of
operations or financial position could affect the results of operations or
financial position of the other group or the market price of the other group's
stock. Net losses of either MCI group or WorldCom group, and any dividends or
distributions on, or repurchases of, MCI stock or WorldCom stock will reduce
Company funds legally available for dividends on MCI stock or WorldCom stock. As
a result, the MCI group combined financial statements should be read along with
the Company's consolidated financial statements.

    The combined financial statements of MCI group reflect the results of
operations, financial position, changes in allocated net worth and cash flows of
MCI group as if MCI group was a separate group for the periods presented. The
financial information included herein, however, may not necessarily reflect the
combined results of operations, financial position, changes in allocated net
worth and cash flows of MCI group had it been a separate, stand-alone group
during the periods presented.

    For financial reporting purposes, the Company has attributed all of its
consolidated assets, liabilities, shareholders' investment, revenues, expenses
and cash flows to either WorldCom group or MCI group. The separate financial
statements give effect to the allocation policies described below under
"Intergroup Allocation Policies". Intergroup allocation policies adopted by the
Company's Board of Directors can be rescinded or amended, or new policies may be
adopted, at the discretion of the Board of Directors, without any prior approval
of shareholders, although no such changes are currently contemplated.

    As integrated businesses, the Company has not historically prepared separate
financial statements of WorldCom group and MCI group. The combined financial
statements of MCI group reflect certain assets, liabilities, revenues and
expenses directly attributable to MCI group as well as allocations based on
methodologies deemed reasonable by management; however, the costs of such
allocated services charged between WorldCom group and MCI group may not
necessarily be indicative of the costs that would have been incurred if WorldCom
group and MCI group had performed these functions entirely as stand-alone
entities. The Company's Board of Directors will have the ability to control
transfers of funds or other assets between WorldCom group and MCI group. The
combined financial statements of MCI group are presented to provide additional
disclosure related to the underlying businesses that comprise MCI group.
Management intends on providing audited financial statements prepared in

                               DECEMBER 31, 2000

(1)  THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES-- (CONTINUED)
accordance with accounting principles generally accepted in the United States,
or GAAP, for MCI group as long as MCI stock is outstanding.

INTERGROUP ALLOCATION POLICIES:

    TRACKING STOCK POLICY STATEMENT

    The Company's Board of Directors has fiduciary duties to all shareholders of
the Company, and no independent fiduciary duties to the holders of WorldCom
stock and MCI stock. The Board of Directors of the Company has adopted a policy
statement regarding WorldCom group and MCI group matters. The Company's Board of
Directors or any special committee appointed by the Company's Board of
Directors, may amend, modify or rescind the policies set forth in this policy
statement from time to time at its sole discretion and without shareholder
approval. The material provisions of the policy statement are as follows:

    GENERAL POLICY.  The policy statement provides that all material matters as
to which the holders of WorldCom stock and MCI stock may have potentially
divergent interests will be resolved in a manner that the Board of Directors of
the Company or any special committee appointed by the Board of Directors
determines to be in the best interests of the Company as a whole, after giving
due consideration to the potentially divergent interests and all other interests
of the holders of the separate series of common stock of the Company that the
Board of Directors or any special committee, as the case may be, deems relevant.
The policy statement provides that the Company will manage the businesses in
WorldCom group and MCI group in a manner intended to maximize the operations,
assets and values of both groups, and with complementary deployment of
personnel, capital and facilities, consistent with their respective business
objectives.

    Under this policy statement, all material transactions which are determined
by the Company's Board of Directors to be in the ordinary course of business
between WorldCom group and MCI group, except for those described in the
paragraphs below, are intended to be on terms consistent with terms that would
be applicable to arm's-length dealings with unrelated third parties.

    CASH MANAGEMENT.  Decisions regarding the investment of surplus cash, the
issuance and retirement of debt, and the issuance and repurchase of common and
preferred stock will continue to be made by the Company's corporate headquarters
on behalf of the groups. Under this centralized cash management system, MCI
group will generally not be allocated any cash balances. Historically, the
Company determined the amount of funding provided to MCI group based on actual
cash used for capital and operating expenses, net of WorldCom group and MCI
group cash receipts.

    CORPORATE ALLOCATIONS:

    Corporate allocations have been attributed and/or allocated to WorldCom
group or MCI group based upon identification of the services specifically
benefiting each group. Such corporate allocations may change at the discretion
of the Company and do not require shareholder approval. Management believes that
the allocation methodologies applied are reasonable. However, it is not
practical to determine whether the allocated amounts represent amounts that
would have been incurred on a stand alone basis. Management believes that the
allocation methods developed will be comparable to the

                               DECEMBER 31, 2000

(1)  THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES-- (CONTINUED)
expected future allocation methods. Explanations of the composition and the
method of allocation for such items are described below.

    SHARED CORPORATE SERVICES.  The Company has directly charged specifically
identifiable costs to WorldCom group and MCI group. Where determinations based
on specific usage alone were impracticable, the Company used other allocation
methods that it believes are fair, including methods based on factors such as
the number of employees and total revenues generated by each group. For the
years ended December 31, 1998, 1999, and 2000, MCI group was allocated
$710 million, $1.6 billion and $1.9 billion of these costs, respectively.

    COMMERCIAL INTER-GROUP TRANSACTIONS.  The MCI group is allocated a
proportion, based on usage, of the Company's fiber optic system costs for use of
the fiber optic systems, which are attributed to WorldCom group. For the years
ended December 31, 1998, 1999 and 2000, fiber optic system costs allocated to
MCI group were $118 million, $189 million and $373 million, respectively. In
addition, WorldCom group is allocated a proportion, based on usage, of the
Company's switching costs for use of the business voice switched services, which
are attributed to MCI group and MCI group is allocated a corresponding decrease
to depreciation expense which, for the years ended December 31, 1998, 1999 and
2000 totaled $20 million, $64 million and $87 million, respectively. Selling,
general and administrative expenses for MCI group include allocated costs for
MCI group's proportionate share of costs associated with buildings, furniture
and fixtures attributed to WorldCom group, and the cost allocated to MCI group
for use of the MCI tradenames as discussed below. For the years ended
December 31, 1998, 1999 and 2000, these allocated costs totaled $90 million,
$331 million and $254 million, respectively.

    All other material commercial transactions in the ordinary course of
business between the groups are intended, to the extent practicable, to be on
terms consistent with terms that would be applicable to arm's-length dealings
with unrelated third parties and will be subject to the review and approval of
the Board of Directors or any special committee. Neither group is under any
obligation to use services provided by the other group, and each group may use
services provided by a competitor of the other group if the Board of Directors
or any special committee determines it is in the best interests of the Company
as a whole.

    ALLOCATION OF INTANGIBLE ASSETS.  Intangible assets consist of the excess
consideration paid over the fair value of net tangible assets acquired by the
Company in business combinations accounted for under the purchase method and
include goodwill, channel rights, developed technology and tradenames. These
assets have been attributed to the respective groups based on specific
identification and where acquired companies have been divided between WorldCom
group and MCI group, the intangible assets have been attributed based on the
respective fair values at date of purchase of the related operations attributed
to each group. Management believes that this method of allocation is equitable
and provides a reasonable estimate of the intangible assets attributable to
WorldCom group and MCI group. All of the tradenames, including the MCI tradename
and the other related MCI tradenames, have been attributed to WorldCom group.
MCI group will be allocated an expense, and the WorldCom group will

be allocated a corresponding decrease in amortization expense for the use of the
MCI tradenames for the next five years based on the following fee schedule:

                         YEAR ENDED
                        DECEMBER 31,

<S>                                                           <C>
  2001......................................................  $27.5 million
  2002......................................................  $30.0 million
  2003......................................................  $35.0 million
  2004......................................................  $40.0 million
  2005......................................................  $45.0 million
</TABLE>

    Any renewal or termination of use of the MCI tradename by MCI group will be
subject to the general policy that our board of directors will act in the best
interests of WorldCom. For each of the years ended December 31, 1998, 1999 and
2000, an expense of $27.5 million per annum was allocated to the MCI group since
the date of acquisition of MCI, for use of the MCI tradenames.

    FINANCING ARRANGEMENTS.  As of January 1, 1999, $6.0 billion of our
outstanding debt was notionally allocated to MCI group and $15.2 billion of our
debt was notionally allocated to WorldCom group. The Company's debt was
allocated between WorldCom group and MCI group based upon a number of factors
including estimated future cash flows and the ability to pay debt service and
dividends of each of the groups. In addition, management considered certain
measures of creditworthiness, such as coverage ratios and various tests of
liquidity, in the allocation process. Management believes that the initial
allocation is equitable and supportable by both WorldCom group and MCI group.
The debt allocated to MCI group will bear interest at a rate indicative of the
rate at which MCI group would borrow from third parties if it was a wholly owned
subsidiary of the Company but did not have the benefit of any guarantee by the
Company. Interest rates will be calculated on a quarterly basis. For purposes of
the combined historical financial statements of each of the groups, debt
allocated to MCI group was determined to bear an interest rate equal to the
weighted average interest rate, excluding capitalized interest, of the Company's
debt plus 1 1/4 percent. Interest allocated to WorldCom group reflects the
difference between our actual interest expense and the interest expense charged
to MCI group. Upon the recapitalization each group's debt will increase or
decrease by the amount of any net cash generated by, or required to fund, the
group's operating activities, investing activities, share repurchases and other
financing activities.

    In 1999, the Company amended its existing $500 million receivables purchase
agreement to $2.0 billion by including additional receivables eligible under the
agreement. As of December 31, 2000, the purchaser owned an undivided interest in
a $3.5 billion pool of receivables which includes the $1.95 billion sold, of
which $1.1 billion and $374 million relate to MCI group, respectively. The
receivables sold were assigned based on specific identification where practical,
or allocated based on total revenues. Management believes that this method of
allocation is equitable and provides a reasonable estimate of the receivables
attributable to the groups.

FAIR VALUE OF FINANCIAL INSTRUMENTS:

    The Company estimates the fair value of attributed MCI group financial
instruments using available market information and appropriate valuation
methodologies. The carrying amounts for cash

(1)  THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES-- (CONTINUED)
and cash equivalents accounts receivable, notes receivable, accounts payable,
accrued liabilities and long-term debt approximate their fair value. The fair
value of long-term debt is determined based on quoted market rates or the cash
flows from such financial instruments discounted at the Company's estimated
current interest rate to enter into similar financial instruments.

CASH AND CASH EQUIVALENTS:

    The Company considers cash in banks and short-term investments with original
maturities of three months or less as cash and cash equivalents.

PROPERTY AND EQUIPMENT:

    Property and equipment are stated at cost. Depreciation is provided for
financial reporting purposes using the straight-line method over the following
estimated useful lives:

<TABLE>
<S>                                                           <C>
Transmission equipment......................................  5 to 10 years
Communications equipment....................................  5 to 20 years
Furniture, fixtures, buildings and other....................  4 to 40 years
</TABLE>

    The Company evaluates the recoverability of property and equipment when
events and circumstances indicate that such assets might be impaired. The
Company determines impairment by comparing the undiscounted future cash flows
estimated to be generated by these assets to their respective carrying amounts.
In the event an impairment exists on property and equipment attributed to MCI
group, a loss will be recognized by MCI group based on the amount by which the
carrying value exceeds the fair value of the asset. If quoted market prices for
an asset are not available, fair market value is determined primarily using the
anticipated cash flows discounted at a rate commensurate with the risk involved.
Losses on property and equipment to be disposed of are determined in a similar
manner, except that fair market values are reduced for the cost to dispose.

    Maintenance and repairs are expensed as incurred. Replacements and
betterments are capitalized. The cost and related reserves of assets sold or
retired are removed from the accounts, and any resulting gain or loss is
reflected in results of operations.

GOODWILL AND OTHER INTANGIBLE ASSETS:

    The major classes of intangible assets attributed to MCI group as of
December 31, 1999 and 2000 are summarized below (in millions):

    Intangible assets are amortized using the straight-line method for the
periods noted above.

    Goodwill is recognized for the excess of the purchase price of the various
business combinations over the value of the identifiable net tangible and
intangible assets acquired. Realization of acquisition-related intangibles,
including goodwill, is periodically assessed by the management of the Company
based on the current and expected future profitability and cash flows of
acquired companies and their contribution to the overall operations of MCI
group.

    Also included in other intangibles are costs incurred to develop software
for internal use. Such costs were $200 million, $356 million and $160 million
for the years ended December 31, 1998, 1999 and 2000, respectively.

RECOGNITION OF REVENUES:

    MCI group records revenues for telecommunications services at the time of
customer usage. Service activation and installation fees are amortized over the
average customer contract life.

CUMULATIVE EFFECT OF ACCOUNTING CHANGES:

    During the fourth quarter of 2000, MCI group implemented SAB 101, which
requires certain activation and installation fee revenues to be amortized over
the average life of the related service rather than be recognized immediately.
Costs directly related to these revenues may also be deferred and amortized over
the customer contract life. As required by SAB 101, MCI group retroactively
adopted this accounting effective January 1, 2000, which resulted in a one-time
expense of $10 million, net of income tax benefit of $7 million. The pro forma
effect of adopting SAB 101 on periods prior to January 1, 2000 was not material
to MCI group's financial position or results of operations.

    MCI group adopted American Institute of Certified Public Accountants'
Statement of Position 98-5, "Reporting on the Costs of Start-up Activities," as
of January 1, 1998. The cumulative effect of this change in accounting principle
resulted in a one-time non-cash expense of $36 million, net of income tax
benefit of $22 million. This expense represented start-up costs incurred
primarily in conjunction with the development and construction of the advanced
messaging network of SkyTel Communications, Inc. ("SkyTel"), which are required
to be expensed as incurred in accordance with this accounting standard.

INCOME TAXES:

    The federal and state income tax liabilities incurred by the Company and
which are determined on a consolidated, combined, or unitary basis will be
allocated between WorldCom group and MCI group in accordance with the Company's
policy statement. The Company currently intends that the income tax expense for
each group and the balance sheet allocation of the expense will be based on a
comparison of the Company's tax expense with the hypothetical tax expense of MCI
group. The tax expense allocable to MCI group will be the amount that MCI group
would have incurred if it had filed tax returns as a separate taxpayer and the
tax expense allocable to WorldCom group will be the excess, if any, of the
Company's tax expense over the tax expense allocable to MCI group. Tax benefits
that cannot be used by a group generating those benefits but can be used on a
consolidated basis will be credited to the group that generated those benefits.

separate tax returns, the provision for income taxes and net income for each
group would not have significantly differed from the amounts reported on the
group's statements of operations for the years ended December 31, 1998, 1999 and
2000. However, the amounts of current and deferred taxes and taxes payable or
refundable attributed to each group on the historical financial statements may
differ from those that would have been allocated had WorldCom group or MCI group
filed separate income tax returns.

    Deferred tax assets and liabilities are based on temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and their respective tax bases.

EARNINGS PER SHARE:

    After the implementation of the recapitalization, the consolidated financial
statements of the Company will present basic and diluted earnings per share for
WorldCom stock and MCI stock using the two-class method. The two-class method is
an earnings formula that determines the earnings per share for WorldCom stock
and MCI stock according to participation rights in undistributed earnings. The
combined financial statements of MCI group will not present earnings per share
because MCI stock is a series of common stock of the Company and MCI group is
not a legal group with a capital structure.

    For purposes of the consolidated financial statements of the Company, basic
earnings per share for MCI stock will be computed by dividing net income for the
period by the number of weighted average shares of MCI stock then outstanding.
Diluted earnings per share of MCI stock will be computed by dividing net income
for the period by the weighted-average number of shares of MCI stock
outstanding, including the dilutive effect of MCI stock equivalents.

CONCENTRATION OF CREDIT RISK:

    A portion of MCI group's revenues is derived from services provided to
others in the telecommunications industry, mainly resellers of long distance
telecommunications service and Internet online services. As a result, MCI group
has some concentration of credit risk among its customer base. MCI group
performs ongoing credit evaluations of its larger customers' financial condition
and, at times, requires collateral from its customers to support its
receivables, usually in the form of assignment of its customers' receivables to
MCI group in the event of nonpayment.

RECLASSIFICATIONS:

    Revenues and line costs for all periods reflect classification changes for
reciprocal compensation and central office based remote access equipment sales
which are now being treated as offsets to cost of sales. Reciprocal compensation
represents a reimbursement of costs for call termination performed on behalf of
other carriers' customers and is determined contractually based on fixed rate
per minute charges to those carriers. Central office based remote access
equipment sales represent the reimbursement of customer specific equipment costs
incurred by MCI group on behalf of the customer as part of service provisioning.
As such, MCI group determined that it is more appropriate to reflect these
reimbursements net of cost. Previously, MCI group recorded these items on a
gross basis as revenues. Revenues and line costs for all periods also reflect
the reclassification of small business and

consumer primary interexchange carrier charges, or PICC, from revenues to line
costs. PICC are flat-rate charges mandated by the FCC which apply to
telecommunications companies that connect to customers through a traditional
phone company's facilities. Effective July 1, 2000, as a result of the FCC's
Coalition for Affordable Local and Long Distance Services, or CALLs order, the
PICC fee is billed directly to the customer by the traditional phone company
rather than to MCI group and rebilled to the customer. Operating income, net
income and the balance sheet are not affected by these reclassifications.

    The effects of these reclassifications on the accompanying combined
statements of operations for the years ended December 31, 1998, 1999 and 2000
are as follows (in millions):

RECENTLY ISSUED ACCOUNTING STANDARDS:

    The Financial Accounting Standards Board's, or FASB's, Statement of
Financial Accounting Standard, or SFAS, No. 133, "Accounting for Derivative
Instruments and Hedging Activities," as amended by SFAS No. 137, "Accounting for
Derivative Instruments and Hedging Activities--Deferral of the Effective Date of
FASB Statement No. 133," and SFAS No. 138, "Accounting for Certain Derivative
Instruments and Certain Hedging Activities," is effective for the Company as of
January 1, 2001. This statement establishes accounting and reporting standards
requiring that derivative instruments (including certain derivative instruments
embedded in other contracts) be recorded in the balance sheet as either an asset
or liability measured at its fair value. This statement requires that changes in
the derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement, and requires a company to formally document,
designate and assess the effectiveness of transactions that receive hedge
accounting. SFAS No. 133 must be applied to (a) derivative instruments and
(b) certain derivative instruments embedded in hybrid contracts that were
issued, acquired, or substantively modified after December 31, 1997 (and, at the
Company's election, before January 1, 1998). The Company has minimal exposure to
derivative financial instruments which, as of December 31, 2000, primarily
consist of option collar transactions designated as cash flow hedges of
anticipated sales of an equity investment and various equity warrants. The
Company believes the adoption of this standard will not have a material effect
on MCI group's combined results of operations or financial position.

(1)  THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES-- (CONTINUED)
    In September 2000 the FASB issued SFAS No. 140 "Accounting for Transfers and
Servicing of Financial Assets and Extinguishments of Liabilities." This
statement provides accounting and reporting standards for transfers and
servicing of financial assets and extinguishments of liabilities and also
provides consistent standards for distinguishing transfers of financial assets
that are sales from transfers that are secured borrowings. SFAS No. 140 is
effective for recognition and reclassification of collateral and for disclosures
relating to securitization transactions and collateral for fiscal years ending
after December 15, 2000, and is effective for transfers and servicing of
financial assets and extinguishments of liabilities occuring after March 31,
2001. The Company believes that the adoption of this standard will not have a
material effect on MCI group's combined results of operations or financial
position.

USE OF ESTIMATES:

    The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and revenues and expenses during the period
reported. Actual results could differ from those estimates.

    The accompanying combined financial statements for MCI group as of and for
the year ended December 31, 1998 are unaudited. Management of MCI group is
solely responsible for these financial statements, without benefit of
independent accounting experts, and believes the 1998 combined financial
statements have been prepared in conformity with GAAP using standards of
materiality consistent with the audited combined financial statements for 1999
and 2000.

(2)  BUSINESS COMBINATIONS--

    The Company has acquired other telecommunications companies offering similar
or complementary services to those offered by MCI group. These acquisitions have
been accomplished through the purchase of the outstanding stock or assets of the
acquired entity for cash, notes, shares of the Company's common stock, or a
combination thereof. The cash portion of acquisition costs has generally been
financed through the Company's bank credit facilities. In addition to the
business combinations described below, the Company or its predecessors completed
smaller acquisitions during the three years ended December 31, 2000.

    On September 14, 1998, the Company acquired MCI Communications Corporation
("MCI") for approximately $40 billion, pursuant to the merger (the "MCI Merger")
of MCI with and into a wholly owned subsidiary of the Company. Upon consummation
of the MCI Merger, the wholly owned subsidiary was renamed MCI Communications
Corporation. Through the MCI Merger, the Company acquired one of the world's
largest and most advanced digital networks, connecting local markets in the
United States to more than 280 countries and locations worldwide.

    The purchase price in the MCI Merger was allocated based on estimated fair
values at the date of acquisition. This resulted in an excess of purchase price
over net assets acquired of which, on a Company consolidated basis,
$3.1 billion was allocated to in-process research and development ("IPR&D") and
$1.7 billion to developed technology, which will be depreciated over 10 years on
a straight-line basis. The remaining excess of $29.3 billion has been allocated
to goodwill and tradename, which are being amortized over 40 years on a
straight-line basis. Such amounts have been allocated to

WorldCom group and MCI group based on the respective fair values of the related
operations allocated to each group. Accordingly, MCI group has been allocated
$775 million, $425 million and $7.0 billion of such IPR&D, developed technology
and goodwill, respectively.

    On January 31, 1998, the Company acquired CompuServe Corporation
("CompuServe"), for approximately $1.3 billion, pursuant to the merger (the
"CompuServe Merger") of a wholly owned subsidiary of the Company with and into
CompuServe. Upon consummation of the CompuServe Merger, CompuServe became a
wholly owned subsidiary of the Company.

    As a result of the CompuServe Merger, each share of CompuServe common stock
was converted into the right to receive 0.609375 shares of Company common stock,
or approximately 56 million Company common shares in the aggregate. Prior to the
CompuServe Merger, CompuServe operated primarily through two divisions:
Interactive Services and Network Services. Interactive Services offered
worldwide online and Internet access services for consumers, while Network
Services provided worldwide network access, management and applications, and
Internet service to businesses. The CompuServe Merger was accounted for as a
purchase; accordingly, operating results for CompuServe attributed to MCI group
have been included from the date of acquisition.

    On January 31, 1998, the Company also acquired ANS Communications, Inc.
("ANS"), from America Online, Inc. ("AOL"), for approximately $500 million, and
entered into five year contracts with AOL under which the Company and its
subsidiaries provide network services to AOL (collectively, the "AOL
Transaction"). As part of the AOL Transaction, AOL acquired CompuServe's
Interactive Services division and received a $175 million cash payment from the
Company. The Company retained the CompuServe Network Services division. ANS
provided Internet access to AOL and AOL's subscribers in the United States,
Canada, the United Kingdom, Sweden and Japan. The AOL Transaction was accounted
for as a purchase; accordingly, operating results for ANS attributed to MCI
group have been included from the date of acquisition.

    The purchase price in the CompuServe Merger and AOL Transaction was
allocated based on estimated fair values at the date of acquisition. This
resulted in an excess of purchase price over net assets acquired of which, on a
consolidated basis, $429 million was allocated to IPR&D. The remaining excess of
approximately $1 billion has been recorded as goodwill, which is being amortized
over 10 years on a straight-line basis. These amounts have been allocated to
WorldCom group and MCI group based on the respective fair values of the related
operations allocated to each group. Accordingly, MCI group has been allocated
$302 million and $446 million of the IPR&D and goodwill, respectively.

    During 1998, 1999 and 2000, the Company recorded other liabilities of
$2.2 billion, $582 million and $29 million, respectively, related to estimated
costs of unfavorable commitments of acquired entities, and other non-recurring
costs arising from various acquisitions and mergers. At December 31, 1998, 1999
and 2000, other liabilities attributed to MCI group related to these accruals
totaled $200 million, $160 million and $106 million, respectively.

    In 1998, MCI group recorded a pre-tax charge of $19 million related to
minimum contractual network lease commitments that expire between 1999 and 2001,
for which MCI Group will receive no future benefit due to the migration of
traffic to owned facilities.

    In connection with 1998 business combinations, the Company made allocations
of the purchase price to acquired IPR&D totaling $429 million in the first
quarter of 1998 related to the CompuServe Merger and AOL Transaction and $3.1
billion in the third quarter of 1998 related to the MCI Merger. These
allocations represent the estimated fair value based on risk-adjusted future
cash flows related to the incomplete projects. At the date of the respective
business combinations, the development of these projects had not yet reached
technological feasibility and the research and development in progress had no
alternative future uses. Accordingly, these costs were expensed as of the
respective acquisition dates. Based on the respective fair values of the related
operations allocated to each group, $1.2 billion of the IPR&D charge was
allocated to MCI group. Management believes that this method of allocation
provides a reasonable estimate of the IPR&D charges attributable to each group.

MCI group shareholders with generally the same terms and conditions as the
current rights agreement. See Note 8 to the Company's consolidated financial

employees of WorldCom group and MCI group. The Company accounts for these plans

and conditions of the Company's options, including exercise price and the period
in which options are exercisable, generally are at the discretion of the
Compensation and Stock Option Committee of the board of directors; however, no
options are exercisable for more than 10 years after date of grant.

Company matches individual employee contributions in selected plans, up to a
maximum level which in no case exceeds 6% of the employee's compensation.
Expenses allocated to MCI group relating to the Company's 401(k) plans were
$14 million, $63 million and $68 million for the years ended December 31, 1998,
1999 and 2000, respectively.

PENSION AND OTHER POST-RETIREMENT BENEFIT PLANS:

    The Company maintains various defined benefit plans and other
post-retirement benefit plans that cover selected eligible employees of WorldCom
group and MCI group. Annual service cost is determined using the Projected Unit
Credit actuarial method, and prior service cost is amortized on a straight-line
basis over the average remaining service period of employees.

(11)  SEGMENT AND GEOGRAPHIC INFORMATION--

    Based on its organizational structure, MCI group operates in four reportable
segments: Consumer, Wholesale, Alternative channels and small business and
Dial-up Internet. MCI group's reportable segments represent business units that
primarily offer similar products and services; however, the business units are
managed separately due to the type and class of customer as well as the
geographic dispersion of their operations. Consumer includes domestic voice
communications services for consumer customers. Wholesale includes voice and
data domestic communications services for wholesale customers. Alternative
channels and small business includes domestic long distance voice and data,
agents, prepaid calling cards and paging services provided to alternative
wholesale and small business customers. Dial-up Internet includes dial-up
Internet access services.

    The Company's chief operating decision-maker utilizes revenue information in
assessing performance and making overall operating decisions and resource
allocations. Communications services are generally provided utilizing the
Company's network facilities, which do not make a distinction between the types
of services. Profit and loss information is reported only on a combined basis to
the chief operating decision-maker and the Company's Board of Directors.
