NOTE 1:  Preparation of Interim Financial Statements

We have prepared the unaudited condensed financial statements in this
report by following Securities and Exchange Commission rules that
permit reduced disclosure for quarterly period reports.  These
financial statements include estimates and assumptions that affect
the reported amounts of assets and liabilities and the amounts of
revenues and expenses.  Actual amounts could differ from those
estimates.  We believe these statements include all adjustments
necessary for a fair statement of results for each period shown.  We
believe our disclosures are adequate to make the presented
information clear.  You should read these financial statements in
conjunction with the financial statements and notes included in our
1997 Annual Report on Form 10-K and the quarterly reports on Form 10-
Q previously filed in 1998.

When reading these financial statements, you should be familiar with
the terminology unique to our business.  We have defined a number of
terms in the glossary on pages 21 and 22.


NOTE 2:  Merger Agreement

On May 11, 1998, our parent (Ameritech Corporation) jointly announced
with SBC Communications Inc. (SBC) a definitive agreement to merge an
SBC subsidiary with Ameritech in a transaction in which each share of
Ameritech common stock will be converted into and exchanged for 1.316
shares of SBC common stock.  After the merger, Ameritech will be a
wholly owned subsidiary of SBC.  The transaction, which was approved
by the Board of Directors of each company, is intended to be
accounted for as a pooling of interests and to be a tax-free
reorganization.  The merger is subject to the satisfaction of certain
conditions and regulatory approvals, as well as approval by the
shareowners of each company.  Ameritech shareowners will vote on the
merger proposal at a special meeting of shareowners to be held on
December 11, 1998.  SBC has called a special meeting of its
shareowners to consider various matters relating to this transaction
on December 10, 1998.

            Item 2 - Management's Discussion and Analysis
                      of Results of Operations
                                  
The following is a discussion and analysis of the changes in
revenues, operating expenses and other income and expenses for the
first nine months of 1998 as compared with the first nine months of
1997.

RESULTS OF OPERATIONS
---------------------
Revenues
--------
Our revenues in the first nine months of 1998 were $2,616.1 million
and were $2,528.2 million for the same period in 1997, an increase of
$87.9 million.  Growth in sales of call management services and
access lines, as well as increases in switched minutes of use were
the primary reasons for the increase.  A favorable court ruling in
Michigan, which increased revenues by about $20 million in the second
quarter of 1998, also contributed to the increase.  Net rate
reductions and decreased long distance revenues partially offset
these increases.

---------------------------------------------------------------------
Local service
-------------
                                  September 30      Increase  Percent
                                  ------------
(dollars in millions)            1998      1997    (Decrease)  Change
 -------------------             ----      ----     --------   ------

Nine Months Ended            $1,203.1   $1,130.5    $  72.6      6.4

Local service revenues include basic monthly service fees and usage
charges, fees for call management services, installation and
connection charges, certain data services and most public phone
revenues.  Local service revenues increased for the nine months ended
September 30, 1998 due largely to increased sales of call management
services, resulting from strong growth in both the number of features
in service and services provided on a pay-per-use basis.  Access line
growth of 3.0% over the prior year period, as well as rate increases,
also contributed to the increase.

There were 5,406,000 access lines in service as of September 30,
1998, compared with 5,247,000 as of September 30, 1997 (restated to
standardize counting of voice-grade equivalent lines).

---------------------------------------------------------------------
Network access
--------------
                                  September 30      Increase  Percent
                                  ------------
(dollars in millions)            1998      1997    (Decrease)  Change
 -------------------             ----      ----     --------   ------

Interstate
----------

Nine Months Ended            $  480.8   $  477.3    $   3.5      0.7

Intrastate
----------

Nine Months Ended            $  167.6   $  154.8    $  12.8      8.3

Network access revenues are fees charged to interexchange carriers
that use our local landline communications network to connect
customers to their long distance networks.  In addition, end users
pay flat rate access fees to connect to the long distance network.
These revenues result from both interstate and intrastate services.

                Management's Discussion and Analysis
                 of Results of Operations (cont'd.)
                                  
Network access (cont'd.)
------------------------
Interstate network access revenues increased for the nine months
ended September 30, 1998 due primarily to an increase in minutes of
use, resulting from overall growth in the volume of calls handled for
interexchange carriers, and greater demand for dedicated services by
Internet service providers and other high-capacity users.  Rate
reductions, combined with a change in reporting classification of pay
phone revenues received from network access to other miscellaneous
revenues beginning in the first quarter of 1998, partially offset
these increases.  This change in classification decreased interstate
network access revenues by approximately $19.6 million in the first
nine months of 1998 compared with the prior year.  Interstate minutes
of use for the nine months ended September 30, 1998 increased by 3.9%
over the prior year.

Intrastate network access revenues increased for the nine months
ended September 30, 1998 largely due to a favorable court ruling in
Michigan which found that interexchange carriers are not entitled to
access charge discounts for intraLATA toll services prior to the time
that Ameritech is allowed to offer interLATA long distance service in
the state of Michigan.  Intrastate network access revenues increased
by about $20 million in the first nine months of 1998 compared with
the prior year period as a result of this ruling.  Several
interexchange carriers have challenged the ruling at the Michigan
Supreme Court and at the Michigan Public Service Commission (MPSC).

Volume increases, largely resulting from increased network usage by
alternative providers of intraLATA toll service, also contributed to
the increase.  Rate decreases, combined with a change in reporting
classification of certain pay phone revenues received from network
access to other revenues partially offset the volume increases.  This
change in classification decreased intrastate network access revenues
by approximately $6.2 million in the first nine months of 1998
compared with the prior year.  Intrastate minutes of use for the nine
months ended September 30, 1998 increased by 11.9% over the same
period last year.

---------------------------------------------------------------------
Long distance service
---------------------
                                  September 30      Increase  Percent
                                  ------------
(dollars in millions)            1998      1997    (Decrease)  Change
 -------------------             ----      ----     --------   ------

Nine Months Ended            $  550.1   $  550.6    $  (0.5)    (0.1)

Long distance service revenues result from customer calls to
locations outside of their local calling areas, but within the same
Local Access and Transport Area (LATA).  Long distance service
revenues decreased for the nine months ended September 30, 1998 due
primarily to volume decreases, resulting from increased competition
from alternative intraLATA toll providers.  Rate increases partially
offset these volume decreases.

---------------------------------------------------------------------
Other
-----
                                  September 30      Increase  Percent

Other (cont'd.)
---------------
Other revenues include revenues derived from directory advertising,
billing and collection services, inside wire installation and
maintenance services and other miscellaneous services.  Other
revenues decreased for the nine months ended September 30, 1998 due
primarily to a decrease in directory advertising revenues, combined
with a decrease in revenues from inside wire installation and
maintenance services.  A change in reporting classification of
certain pay phone revenues from network access to other revenues, as
previously discussed, combined with increased sales of equipment and
other nonregulated services, such as voice messaging and billing and
collection services, partially offset the decrease.

We have entered into a new agreement with Ameritech Publishing, Inc.
(API), a wholly owned Ameritech subsidiary, for the publication and
distribution of directories.  This agreement, which was effective
July 1, 1997, reduced our revenues from directory services by
approximately $38.6 million in the first three quarters of 1998
compared with the prior year period.

---------------------------------------------------------------------
Operating expenses
------------------
Total operating expenses for the nine months ended September 30, 1998
increased $96.4 million, or 5.5 percent to $1,848.7 million.
Increases in other operating expenses and depreciation and
amortization expenses were the primary reasons for the increase, as
discussed below.

---------------------------------------------------------------------
Employee-related expenses
-------------------------
                                  September 30      Increase  Percent
                                  ------------
(dollars in millions)            1998      1997    (Decrease)  Change
 -------------------             ----      ----     --------   ------

Nine Months Ended            $  503.0   $  504.0    $  (1.0)    (0.2)

Employee-related expenses decreased for the nine months ended
September 30, 1998 due primarily to lower average force levels,
reduced overtime expenses and decreases to other employee benefit
expenses.  Wage rate increases partially offset the decrease.

In July 1998 the Communications Workers of America (CWA) ratified a
new contract, which was effective August 9, 1998 and expires on March
31, 2001.  The contract provides basic wage increases of 11.2%
(compounded) over the contract period and a one-time $500 signing
bonus per employee, and also addresses benefits, pensions, work-rules
and other wage-related items.  The CWA represents approximately 90%
of our employees.

We employed 11,634 employees as of September 30, 1998, compared with
12,144 as of September 30, 1997.

Depreciation and
  amortization
------------------
                                  September 30      Increase  Percent
                                  ------------
(dollars in millions)            1998      1997    (Decrease)  Change
 -------------------             ----      ----     --------   ------

Nine Months Ended            $  416.1   $  390.2    $  25.9      6.6

Depreciation and amortization expense increased for the nine months
ended September 30, 1998 due primarily to higher property, plant and
equipment balances.  Higher depreciation rates on certain asset
categories also contributed to the increases, as we used shorter
depreciable lives for newer technologies.

---------------------------------------------------------------------
Other operating expenses
------------------------
                                  September 30      Increase  Percent
                                  ------------
(dollars in millions)            1998      1997    (Decrease)  Change
 -------------------             ----      ----     --------   ------

Nine Months Ended            $  810.1   $  742.6    $  67.5      9.1

Other operating expenses increased for the nine months ended
September 30, 1998 due primarily to higher access charge expenses
resulting from state commission rulings regarding calls to the
Internet.  These rulings (which we are contesting) require local
exchange carriers to pay reciprocal compensation for calls by their
customers to the Internet via Internet service providers (ISPs) who,
in turn, are customers of competing local exchange carriers.  As of
September 30, 1998, we had accrued all disputed charges and set aside
approximately $45.3 million in segregated funds pending final
resolution of these disputes.  In October 1998, we made reciprocal
compensation payments, under protest, of approximately $34.8 million
to competing carriers from these segregated funds.

Increased contract and affiliated services related to systems
programming and network support also contributed to the increase.  A
decrease in uncollectibles, resulting from improved credit screening
and collection efforts, combined with lower material costs and right-
to-use fees for switching system software, partially offset these
increases.

---------------------------------------------------------------------
Taxes other than income taxes
-----------------------------
                                  September 30      Increase  Percent
                                  ------------
(dollars in millions)            1998      1997    (Decrease)  Change
 -------------------             ----      ----     --------   ------

Nine Months Ended            $  119.5   $  115.5    $   4.0      3.5

Taxes other than income taxes consist of property taxes, gross
receipts taxes and other taxes not directly related to earnings.
Taxes other than income taxes increased in the period ended September
30, 1998 due primarily to increased property taxes, resulting from
higher assessed valuation and property tax rates.  Lower use tax
expenses in the first nine months of 1998 compared with the prior
year period partially offset the decrease.

Nine Months Ended            $   62.1   $   62.2    $  (0.1)    (0.2)

Interest expense decreased for the nine months ended September 30,
1998 due primarily to a decrease in interest on short-term debt,
reflecting lower average balances in the Ameritech short-term funding
pool.

Nine Months Ended            $    9.4   $    6.0    $   3.4     56.7

Other income, net includes equity in earnings of affiliates, interest
income and other nonoperating items.  Other income increased for the
nine months ended September 30, 1998 due primarily to increased
income on funds deposited in the Ameritech short-term funding pool,
partially offset by decreased equity earnings from Ameritech
Services, Inc. (ASI).

Nine Months Ended            $  262.7   $  253.0    $   9.7      3.8

Income taxes increased for the nine months ended September 30, 1998
due primarily to the tax impacts of the centralization of
administration of benefits for employees.  A decrease in pretax
earnings, as discussed above, partially offset the increase.

---------------------------------------------------------------------
Ratio of earnings to fixed charges
----------------------------------
The ratio of earnings to fixed charges for the nine months ended
September 30 was 11.34 in 1998 and 11.33 in 1997.

OTHER MATTERS
-------------
Regulatory considerations
-------------------------
The Telecommunications Act of 1996

In general, the Telecommunications Act of 1996 (the "1996 Act")
includes provisions designed to open local exchange markets to
competition and afford the Bell operating companies ("BOCs") or their
affiliates the competitive opportunity to provide interLATA (long
distance) services.  Under the 1996 Act, the BOCs' ability to provide
in-region long distance services is dependent upon their satisfaction
of, among other conditions, a 14 point "competitive checklist" of
specific requirements for opening the local market to competition.

In late 1997, a U.S. District Court in Texas ruled that certain line-
of-business restrictions in the 1996 Act, including the requirement
in Section 271 that the BOCs must comply with the competitive
checklist before being permitted to provide long distance services,
constitute an unconstitutional bill of attainder by virtue of their
exclusive applicability to the BOCs.  On September 4, 1998, the U.S.
Court of Appeals for the Fifth Circuit reversed that decision, and
petitions for certiorari are pending before the U.S. Supreme Court.

In two other cases, similar constitutional challenges have been
presented to the U.S. Court of Appeals for the District of Columbia
Circuit (the "D.C. Circuit Court").  In May 1998, the D.C. Circuit
Court found that Section 274 of the 1996 Act, covering electronic
publishing activities, did not constitute an unconstitutional bill of
attainder.  The second action pending before the D.C. Circuit Court,
in which Ameritech has intervened, challenges the constitutionality
of the long distance provisions of Section 271 of the 1996 Act.  The
D.C. Circuit Court heard oral arguments on this case in September 1998.

Local interconnection and unbundled access

In July 1997, and in an October 1997 rehearing, the U.S. Circuit
Court of Appeals for the Eighth Circuit (the "Eighth Circuit Court")
vacated several provisions of an August 1996 FCC order regarding the
interconnection provisions of the 1996 Act (the "1996 FCC Order"),
ruling that such provisions represented improper preemptions of state
authority or were inconsistent with statutory requirements of the
1996 Act.  The Eighth Circuit Court ruled, among other things, that:
the states have exclusive jurisdiction over the pricing for local
interconnection, unbundled network elements and local service resale
involving incumbent local exchange carriers ("ILECs") and competitive
local exchange carriers ("CLECs"); the FCC cannot lawfully allow
CLECs to "pick and choose" among isolated, individual provisions from
other interconnection agreements; and the FCC cannot require ILECs
either to recombine or "rebundle" unbundled network elements for
CLECs or to provide them with a preassembled network platform (or
existing combinations of two or more network elements) at network
element prices.  These rulings of the Eighth Circuit Court were
appealed by various parties, including the FCC.

The Eighth Circuit Court upheld certain aspects of the 1996 FCC
Order.  These included, among other things:  the classification of
operational support services, operator services, directory assistance
and vertical services as unbundled network elements; the definition
of "technically feasible" interconnection to exclude economic
considerations; and the ability of CLECs to provide complete
telecommunications services by recombining network elements without
providing any of their own facilities.  Ameritech has appealed these
matters, among others.

Regulatory considerations (cont'd.)
-----------------------------------
Local interconnection and unbundled access (cont'd.)

The U.S. Supreme Court has agreed to review the Eighth Circuit Court
decision and heard oral arguments on the case in October 1998.

In August 1997, the FCC revised its local competition rules and
required ILECs to make available a new purported network element
known as "shared transport," which would include access to all of an
ILEC's transmission facilities.  Ameritech and other ILECs appealed
this matter to the Eighth Circuit Court.  On August 10, 1998, the
Eighth Circuit Court upheld the FCC's determination that shared
transport is a network element and that it should be made available
by ILECs to entrants on an unbundled basis.  In September 1998, we
filed a petition for reconsideration of this decision by the Eighth
Circuit Court.

At present, local interconnection matters and unbundled network
element pricing continue to be resolved through interconnection
agreement negotiations or state commission arbitration provisions.
We are continuing to negotiate and enter into interconnection
agreements and pursue, through appropriate proceedings, timely
recovery of the costs of providing interconnection services so as to
promote a fair competitive environment, especially as local and long
distance markets are opened to competition at different times.  The
outcome of these activities is subject to significant legal and
regulatory uncertainties, as outlined above.

Reciprocal compensation

A number of CLECs are engaged in regulatory and judicial proceedings
with us and various other ILECs with respect to the payment of
reciprocal compensation to the CLECs for calls originating on the
ILECs' networks for dial-up connections to access the Internet via
ISPs served by the CLECs' networks.  The CLECs have asserted that
such reciprocal compensation is provided for by interconnection
agreements between the CLECs and the ILECs.  Together with other
ILECs, we have maintained that we are not required to make such
reciprocal compensation payments, because such traffic is interstate
access service, not local, and therefore is not covered by applicable
local interconnection agreements.

A U.S. District Court in Illinois has ruled that Ameritech's Illinois
landline communications subsidiary is required to make reciprocal
compensation payments in these circumstances under its applicable
interconnection agreements.  This order is on appeal to the U.S.
Court of Appeals for the Seventh Circuit.  Cases involving appeals by
other Ameritech subsidiaries of adverse regulatory determinations are
pending in U.S. District Courts in Michigan and Wisconsin.  The U.S.
District Court for the Western District of Michigan denied
Ameritech's motion for a preliminary injunction and stayed all
further proceedings pending a ruling by the FCC in the matter
referenced below.  Also, in a state court lawsuit filed by TCG, the
Ingham County Circuit Court issued a Writ of Mandamus, directing
Ameritech to comply with the MPSC's January 28, 1998 Order.
Ameritech has made payments, under protest, required by that Order.
The Public Utilities Commission of Ohio recently ruled that
Ameritech's Ohio landline communications subsidiary is required to
make reciprocal compensation payments, but stayed its order pending
rehearing.

On October 30, 1998, the FCC issued a Memorandum Opinion and Order in
which it found that a service offering by another ILEC, permitting
ISPs to furnish their customers with high speed access to the
Internet through a dedicated connection, is

                                  
                               Page 12

Regulatory considerations (cont'd.)
-----------------------------------
Reciprocal compensation (cont'd.)

an interstate service that is properly tariffed at the federal level.
In so ruling, the FCC considered the totality of the communication as
an end-to-end transmission between an end user and the Internet
website accessed by the end user, and rejected the argument that such
a communication should be separated into two components (consisting
of an ILEC-provided intrastate telecommunications service that
terminated at the ISP's local server, and an interstate information
service provided by the ISP).  The FCC expressly limited its decision
only to the high speed, dedicated access connection between an end
user subscriber and an ISP as described in the proposed tariff, and
made no determination whether ILECs generally should be required to
pay reciprocal compensation when they exchange Internet traffic with
CLECs.  The FCC has indicated its intention to provide separate
guidance in the near future on the jurisdictional nature of dial-up
access via a LEC's local switch.

We believe that this recent FCC Order is consistent with our view
that Internet traffic is appropriately classified as interstate and
that reciprocal compensation is not required for dial-up access in
the circumstances described above.  We also believe that our view
should ultimately be upheld in pending or future appellate judicial
proceedings or through FCC determination.  However, there can be no
assurance as to that outcome or that we will not be required to
continue to make such reciprocal compensation payments under existing
interconnection agreements.  We are making periodic accruals of
amounts which may become payable in the event our view is not
ultimately upheld.

Universal service, access charge reform and price caps

In May 1997, the FCC issued three closely-related orders that
established rules to implement the universal service provisions of
the 1996 Act (the "Universal Service Order") and to revise both
interstate access charge pricing (the "Access Reform Order") and the
price cap plan for certain ILECs (the "Price Cap Order").

Universal service  -  The FCC's Universal Service Order provides that
all interstate telecommunications providers will be required to
contribute to universal service funding, based on retail
telecommunications revenues.  The Universal Service Order establishes
a multi-billion dollar interstate universal service fund to help link
eligible schools and libraries and low-income consumers and rural
health care providers to the global telecommunications network
(including the Internet). The FCC directed the phase-in of these
funds during 1998, with a reduced funding rate for the first nine
months of 1998.

Access charge reform  -  In its May 1997 order on interstate access
charge pricing (the "Access Reform Order"), the FCC restructured
interstate access pricing and adopted changes to its tariff structure
requiring ILECs to use rates that reflect the type of costs incurred.
The Access Reform Order also continued in place existing rules by
which ILECs may not assess interstate access charges on ISPs and
purchasers of unbundled network elements.  Together with other ILECs,
Ameritech has appealed certain aspects of the Access Reform Order to
the Eighth Circuit Court, where a decision is pending.

We also have implemented state changes that mirror the federal access
reform structure.  Various interexchange carriers opposing such
changes have filed complaints before the Michigan state commission.
On October 26, 1998, in response

                                  
                               Page 13

Regulatory considerations (cont'd.)
-----------------------------------
Universal service, access charge reform and price caps (cont'd.)

Access charge reform (cont'd.)  -  to such a complaint, the Michigan
Public Service Commission (the "MPSC") ordered us to split the
Michigan intrastate primary interexchange carrier charge ("PICC")
into two separate per line components, with one-half of the total
charge payable by the intraLATA toll carrier and the other half by
the interLATA toll carrier; accordingly, the revenues we receive from
this charge will decrease to the extent that we are the intraLATA
toll carrier.  In addition, the MPSC required that these changes be
made retroactive to January 1, 1998, when the initial tariffs for
this charge were filed.  The MPSC did not adjust the overall amount
of the PICC, but did require the filing of additional information on
that subject for consideration in subsequent proceedings.  We intend
to appeal the MPSC's order.  The MPSC denied our request for a stay
of this order.

Price caps  -  Our interstate services are subject to price cap
regulation, which limits prices rather than profits.  The Price Cap
Order effectively reduced access charges by increasing the price cap
productivity offset factor to 6.5% from the previous 5.3% and by
applying this factor uniformly to all access providers.  The order
also required LECs subject to price cap regulation to set their 1997
price cap index assuming that the 6.5% factor had been in effect
since July 1996.  Certain parties have sought judicial review of the
Price Cap Order, and a decision by the D. C. Circuit Court with
respect to these matters is now pending.

We currently cannot predict the precise impact of these regulatory
changes on our business, especially as their nature and timing may
evolve in connection with judicial and FCC consideration of other
provisions of the 1996 Act.

Number portability

On May 5, 1998, the FCC entered an order to allow us and other
telecommunications carriers to recover over a five-year period their
carrier-specific costs of implementing long-term number portability.
Long-term number portability allows customers to retain their local
telephone numbers in the event they change local exchange carriers.
We are completing implementation of long-term number portability by
the end of 1998, in compliance with an FCC-mandated schedule, and
plan to file our number portability surcharge rates and cost support
with the FCC in time to begin to assess the surcharge in February
1999.

Dial 1 +

In 1996, the Michigan Public Service Commission (MPSC) issued two
Orders requiring Michigan Bell to provide statewide dialing parity
(the ability to choose an alternate carrier for intraLATA toll calls
by dialing 1 before the phone number), or to discount intraLATA toll
access rates by 55% where dialing parity was not implemented.  In
January 1997, the Michigan Court of Appeals issued a stay of the MPSC
Orders pending a determination of Ameritech Michigan's appeal on the
merits.

In May 1998, the Court of Appeals issued a decision which reversed
the 1996 MPSC Orders.  The Court concluded that, under the plain
language of the Michigan Telecommunications Act (MTA), Ameritech was
required to provide intraLATA toll dialing parity to no more than ten
percent of its customers on January 1, 1996, until Ameritech obtained
interLATA relief.  The Court of Appeals also reversed the imposition
of a 55% discount on access charges.

-----------------------------------
Dial 1 + (cont'd.)

The Michigan Supreme Court granted applications for leave to appeal
filed by AT&T, MCI, the MPSC and the Michigan Attorney General.  A
decision on the merits of the appeal is expected in late 1999.  While
its application for leave to appeal was pending, MCI filed another
MPSC complaint asking the Commission to reinstate the 55% discount on
access charges and to issue a new mandate for dialing parity.  An
MPSC Order is expected in January 1999.

To date we are continuing to provide Dial 1 + capability in Michigan
to over 70% of our access lines on a voluntary basis.

Competitive environment
-----------------------
With the passage of the 1996 Act and other regulatory initiatives,
our local service markets have been more extensively opened to new
competitors, many of which are believed to have initially targeted
high-volume business customers in densely populated areas.
Interconnection agreements with competitive service providers require
us to provide interconnection or access to unbundled network elements
at cost-based rates and telecommunications services at discounted,
wholesale rates.  These agreements and applicable tariffs may result
in some downward pressure on local service revenues, as a portion of
our revenue shifts from local service at retail prices to network
access and wholesale services at lower rates.  Further, FCC rules
require that interLATA long distance service be offered by a separate
Ameritech subsidiary.  As a result, Ameritech's entry into this
market will not generate revenues for Michigan Bell to offset the
potential revenue decline brought by local service competition.  We
cannot predict with certainty the impact that these and other
developments ultimately may have on our future business, results of
operations or financial condition.

Year 2000 readiness
-------------------
The Year 2000 issue exists because many computer systems and
applications, including those embedded in equipment and facilities,
use two digit rather than four digit date fields to designate an
applicable year.  As a result, the systems and applications may not
properly recognize the year 2000 or process data which includes it,
potentially causing data miscalculations or inaccuracies or
operational malfunctions or failures.

Ameritech has established a centrally-managed, company-wide
initiative to identify, evaluate and address Year 2000 issues.  Begun
in May 1996, Ameritech's Year 2000 effort covers network and
supporting infrastructure for provision of local switched and data
telecommunications services, as well as operational and financial
information technology ("IT") systems and applications, end-user
computing resources and building systems, such as security, elevator
and heating and cooling systems.  In addition, the project includes a
review of the Year 2000 compliance efforts of key suppliers and other
principal business partners and, as appropriate, the development of
joint business support and continuity plans for Year 2000 issues.
While this initiative is broad in scope, it has been structured to
identify and prioritize our efforts for mission critical systems,
network elements and products and key business partners.

                                  
                               Page 15

Year 2000 readiness (cont'd.)
-----------------------------
Work is progressing in the following phases:  inventory, assessment,
remediation, testing, deployment and monitoring.  Although the pace
of the work varies among Ameritech's business units and the phases
are often conducted in parallel, as of September 30, 1998, the
inventory and assessment phases have been substantially completed and
the remediation and testing phases are in progress.

We expect that most of our mission critical systems, network elements
and products will be remediated and redeployed in January 1999,
subject to additional Year 2000 testing and responsive actions.
Ameritech's ability to meet that target is dependent upon a variety
of factors, including the timely provision of necessary upgrades and
modifications by suppliers and contractors.  In some instances,
upgrades or modifications are not expected to be available until late
1998 or early 1999; accordingly, Ameritech's testing and redeployment
of affected items may be delayed until later in 1999.  In addition,
Ameritech has no method of ensuring that third parties on whom we
depend for essential services (such as electric utilities,
interexchange carriers, etc.) will convert their critical systems and
processes in a timely manner.  Failure or delay by any of these
parties could significantly disrupt our business.  However, Ameritech
has established a supplier compliance program, and is working with
its key suppliers to minimize such risks.

Ameritech and all of its subsidiaries, including Michigan Bell,
expect to incur total expenses of approximately $195 million through
2001 in connection with anticipated Year 2000 efforts, in addition to
approximately $57 million in total expenses incurred through
September 30, 1998 for matters historically identified as Year 2000-
related.  The timing of these expenses may vary and is not
necessarily indicative of readiness efforts or progress to date.  We
anticipate that a portion of our Year 2000 expenses will not be
incremental costs, but rather will represent the redeployment of
existing IT resources.  Ameritech as a whole also expects to incur
certain capital improvement costs (totaling approximately $30
million) to support this project.  Such capital costs are being
incurred sooner than originally planned, but, for the most part,
would have been required in the normal course of business.

As part of its Year 2000 initiative, Ameritech is evaluating
scenarios that may occur as a result of the century change and is in
the process of developing contingency and business continuity plans
tailored for Year 2000-related occurrences.  Contingency planning to
maintain and restore service in the event of natural disasters, power
failures and software-related problems has been part of our standard
operation for many years, and we are working to leverage this
experience in the development of plans tailored to meet Year 2000-
related challenges.  This work is being performed through centrally-
coordinated, company-wide teams organized by critical business
functions (including ordering, provisioning, maintenance, billing and
power).  Our contingency and business continuity plans are expected
to assess the potential for business disruption in various scenarios,
and to provide for key operational back-up, recovery and restoration
alternatives.

The above information is based on current best estimates, which were
derived using numerous assumptions of future events, including the
availability and future costs of certain technological and other
resources, third party modification actions and other factors.  Given
the complexity of these issues and possible unidentified risks,
actual results may vary materially from those

anticipated and discussed above.  Specific factors that might cause
such differences include, among others, the availability and cost of
personnel trained in this area, the ability to locate and correct
all affected computer code, the timing and success of remedial
efforts of our third party suppliers and similar uncertainties.

New accounting pronouncements
-----------------------------
FAS 131

In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (FAS) 131, "Disclosures
about Segments of an Enterprise and Related Information." This
statement supersedes FAS 14, "Financial Reporting of Segments of a
Business Enterprise," by establishing new standards for the way that
a public business enterprise reports operating segment information in
its annual and interim financial statements.  In general, FAS 131
requires reporting of financial information as it is used by senior
company management for evaluating performance and deciding how to
allocate resources.  The statement is effective in 1998, but need not
be applied to interim financial statements this year.  Comparative
information for earlier years must be restated.  We will adopt FAS
131 beginning with our 1998 Annual Report on Form 10-K.

AICPA SOP 98-1

In March 1998, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) 98-1, "Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use."
This SOP provides authoritative guidance for the capitalization of
certain computer software costs developed or obtained for our
internal applications, such as:

-  external direct costs of materials and services, such as
   programming costs,
-  payroll costs for employees devoting time to the software project,
   and
-  interest costs to be capitalized.
Costs incurred during the preliminary project stage, as well as
training and data conversion costs, are to be expensed as incurred.
The SOP is effective for fiscal years beginning after December 15,
1998. Ameritech plans to adopt SOP 98-1 in the first quarter of 1999,
and estimates that the impact of adoption will be to decrease
software-related expenses for Ameritech and all its subsidiaries,
including Michigan Bell, by $200 million to $250 million in the year
of adoption.  We have historically expensed most computer software
costs as incurred.

FAS 133

In June 1998 the FASB issued FAS 133, "Accounting for Derivative
Instruments and Hedging Activities."  This statement provides
standardized accounting and disclosure guidance for derivative
instruments and the derivative portion of certain similar contracts.
It amends FAS 52, "Foreign Currency Translation" and FAS 107,
"Disclosures about Fair Values of Financial Instruments," and it
supersedes a number of financial accounting standards previously
issued by the FASB and several interpretations from the Emerging
Issues Task Force.

                                  
                               Page 17

FAS 133 (cont'd.)

The statement requires entities that use derivative instruments to
measure these instruments at fair value and record them as assets or
liabilities on the balance sheet.  It also requires entities to
reflect the gains or losses associated with changes in the fair value
of these derivatives, either in earnings or as a separate component
of comprehensive income, depending on the nature of the underlying
contract or transaction.

FAS 133 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999, and is to be adopted as of the
beginning of the fiscal year.  At the time of adoption, all
derivative instruments are to be measured at fair value and recorded
on the balance sheet.  Any differences between fair value and
carrying amount at that time will be recorded as a cumulative effect
of a change in accounting principle, in either net income or other
comprehensive income, as appropriate.  Adoption of this statement may
or may not have a material impact on our results of operations or
financial position in a given year, depending upon the nature and
magnitude of derivative activity that we engage in and the changes in
market conditions with respect to interest rates or other underlying
values.  We have not yet quantified the impacts of the initial
adoption of FAS 133 on our results of operations or financial
condition, nor have we determined when we will implement the new
standard.
