Item 3. Key Information



SELECTED FINANCIAL DATA



The
selected consolidated financial data set forth below have been derived from our audited consolidated financial statements for each of the five years in the period ended December 31, 2004, which have been reported on by Mancera, S.C., a member of
Ernst & Young Global, an independent, registered public accounting firm. The selected consolidated financial data should be read in conjunction with, and are qualified in their entirety by reference to, our consolidated financial statements and
notes thereto included elsewhere in this Annual Report.



Our
consolidated financial statements have been prepared in accordance with generally accepted accounting principles in Mexico, or Mexican GAAP, which differ in certain respects from generally accepted accounting principles in the United States, or U.S.
GAAP. Note 19 to our audited consolidated financial statements provides a description of the principal differences between Mexican GAAP and U.S. GAAP, as they relate to us; a reconciliation to U.S. GAAP of operating income, net income and total
stockholders equity; and a condensed statement of cash flows under U.S. GAAP.



Pursuant to Mexican GAAP, in the consolidated financial statements and the selected consolidated financial data set forth below:



| |  |  | nonmonetary assets (excluding plant, property and equipment of non-Mexican origin) and stockholders equity are restated for inflation based on the Mexican National Consumer
Price Index;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | plant, property and equipment of non-Mexican origin are restated based on the rate of inflation in the country of origin and converted into Mexican pesos using the prevailing
exchange rate at the balance sheet date;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | gains and losses in purchasing power from holding monetary assets and liabilities are recognized in income; and
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | all financial statements are restated in constant pesos as of December 31, 2004.
| | - |  | --------------------------------------------------------------------------------



We have not reversed the effect of inflation accounting under Mexican GAAP in the reconciliation to U.S. GAAP of our net income and
stockholders equity, except with respect to the methodology for restatement of plant, property and equipment of non-Mexican origin. See Note 19 to our consolidated financial statements.

RISK FACTORS



Risks Relating to Our Business
Generally



Increasing competition in Mexico and the
other countries in which we operate could adversely affect our revenues and profitability



We face significant competition in Mexico and the other countries in which we operate, which could result in decreases in current and potential customers,
revenues and profitability. Governmental authorities in many of these countries continue to grant new licenses and concessions to new market entrants, which results in increased competition in those countries. In addition, technological developments
are increasing cross-competition in certain markets, such as between wireless providers and fixed-line operators.



In Mexico, competition in local service, principally from wireless service providers, has been developing since 1999. In December 2004, there were
approximately 38 million cellular lines in service, compared with approximately 18.1 million fixed lines in service (17.2 million of which are part of our network). At present, 18 fixed-line local operators have been granted licenses, primarily in
Mexico City, Guadalajara, Monterrey, Puebla and other large cities.



We have also begun to face new competition in Mexico from cable television providers, who have recently been authorized by the Communications Ministry (Secretaría de Comunicaciones y Transportes) to provide voice-transmission
services to local fixed-line telecommunications operators and data and broadband Internet services to the Mexican public.



The effects of competition on our business are highly uncertain and will depend on a variety of factors, including economic conditions; regulatory
developments; the behavior of our customers and competitors; and the effectiveness of measures we take.



Dominant carrier regulations and other regulatory developments could hurt our business by limiting our ability to pursue competitive and profitable
strategies



Our business is subject to extensive
regulation, and it can be adversely affected by changes in law, regulation or regulatory policy. The Mexican Competition Commission has determined that we are a dominant provider of certain telecommunications services, and Mexican law provides for
the regulatory authorities to impose additional regulations on a dominant provider. In the past several years, the Mexican Competition Commission and the Mexican Federal Telecommunications Commission (Comisión Federal de
Telecomunicaciones, or Cofetel) have adopted resolutions and regulations that apply specifically to us as a dominant carrier. We have successfully challenged these resolutions and regulations in Mexican federal court. We cannot predict whether
the Mexican Competition Commission or Cofetel will issue new resolutions or regulations that are substantially similar to the successfully challenged dominant carrier provisions, and if so, whether our judicial challenges will be successful in the
future. We believe that if dominant carrier regulations are eventually implemented, the new rules and the related regulatory procedures will reduce our flexibility to adopt competitive tariff policies.



World Trade Organization dispute settlement between the United States
and Mexico will result in changes in regulation that may affect our business



In August 2000, the United States initiated a World Trade Organization, or WTO, dispute settlement against Mexico regarding alleged illegal barriers to competition in the Mexican telecommunications market. In June
2004, the United States and Mexico reached an agreement under which Mexico has eliminated its uniform settlement rate system, its proportional return system and its



5

##### Table of Contents

requirement that the Mexican carrier with the greatest share of outgoing traffic to a particular country negotiate the
settlement rate on behalf of all Mexican carriers for that country. Mexico also agreed to introduce new regulations authorizing the resale of outgoing international long distance service. Mexico is expected to adopt regulations authorizing resale of
outgoing international long distance service as well as domestic long distance, local, cellular and other services. These regulations are expected to be adopted by the end of July 2005. We expect that these new regulations will likely affect our
business and competition in the future and will put downward pressure on the prices we charge our customers for those services.



Shifting usage patterns could adversely affect our revenues



Our fixed-line network services face increasing competition due to shifting usage patterns resulting from the adoption of
popular new technologies, including wireless devices for voice and other communications, and the subsequent substitution of these technologies for fixed-line phones. For example, we estimate that an increasing proportion of calls that previously
would have been made over our fixed-line network are now being made on wireless telephones and voice over IP, or VoIP, services outside our network, for which we receive no revenues. There can be no assurance that this process will not adversely
affect our traffic volume and our results of operations.



We have invested in countries in which we have limited experience, and we may be unsuccessful in addressing the new challenges and risks they present



We have invested in a growing number of telecommunications businesses outside our historical core activity of providing
fixed-line telecommunications services in Mexico, and we plan to continue to do so in the rest of Latin America. These investments have been made in some countries in which we have little experience and may involve risks to which we have not
previously been exposed. Some of the investments are in countries that may present different or greater risks than Mexico, such as Brazil, Chile, Argentina, Peru and Colombia. We cannot assure you that these investments will be successful.



Risks Relating to Our Controlling Shareholder and Capital Structure



We are controlled by one shareholder



A majority of the voting shares of our company (70.6%
as of May 17, 2005) is owned by Carso Global Telecom, S.A. de C.V., or Carso Global Telecom, which is controlled by Carlos Slim Helú and members of his immediate family who, taken together, own a majority of the common stock. Carso Global
Telecom has the effective power to designate a majority of the members of our Board of Directors and to determine the outcome of other actions requiring a vote of the shareholders, except in very limited cases that require a vote of the holders of L
Shares.



The protections afforded to minority
shareholders in Mexico are different from those in the United States



Under Mexican law, the protections afforded to minority shareholders are different from those in the United States. In particular, the law concerning fiduciary duties of directors is not well developed, there is no
procedure for class actions or shareholder derivative actions and there are different procedural requirements for bringing shareholder lawsuits. As a result, in practice it may be more difficult for minority shareholders of Telmex to enforce their
rights against us or our directors or controlling shareholder than it would be for shareholders of a U.S. company.

##### Table of Contents

We engage in transactions with related parties that may create the potential for conflicts of
interest



We engage in transactions with certain
subsidiaries of Grupo Carso, S.A. de C.V., or Grupo Carso, and Grupo Financiero Inbursa, S.A. de C.V., or Grupo Financiero Inbursa. Transactions with subsidiaries of Grupo Carso include the purchase of network construction services and materials,
and transactions with Grupo Financiero Inbursa include banking services and insurance. We also have ongoing operational relationships with América Móvil, which is controlled by América Telecom, S.A. de C.V., or América
Telecom. América Telecom, Carso Global Telecom, Grupo Carso and Grupo Financiero Inbursa are controlled by Carlos Slim Helú and members of his immediate family who, taken together, own a majority of the common stock of each company.



We also make investments jointly with related parties, sell
our investments to related parties and buy investments from related parties. Recent investment transactions with related parties include our investment in the equity securities of MCI, Inc., or MCI, which we and others who may be deemed to be under
common control with us sold to Verizon Communications, Inc. on May 17, 2005.



Our transactions with related parties may create the potential for conflicts of interest.



Holders of L Shares and L Share ADSs have limited voting rights



Our bylaws provide that holders of L Shares are not permitted to vote except on such limited matters as the transformation
or merger of Telmex or the cancellation of registration of the L Shares with the Mexican National Banking and Securities Commission or any stock exchange on which they are listed. If you hold L Shares or L Share ADSs, you will not be able to vote on
most matters, including the declaration of dividends, that are subject to a shareholder vote in accordance with our bylaws.



Holders of ADSs are not entitled to attend shareholders meetings, and they may only vote through the depositary



Under Mexican law, a shareholder is required to deposit its shares with a
Mexican custodian in order to attend a shareholders meeting. As long as a shareholder holds shares in ADS form, the shareholder will not be able to satisfy this requirement. There can be no assurance that holders of ADSs will receive notice of
shareholders meetings from our ADS depositary in sufficient time to enable such holders to return voting instructions to the ADS depositary in a timely manner. In the event that instructions are not received with respect to any shares
underlying ADSs, the ADS depositary will, subject to certain limitations, grant a proxy to a person designated by us. In the event that this proxy is not granted, the ADS depositary will vote these shares in the same manner as the majority of the
shares of each class for which voting instructions are received.



You may not be entitled to participate in future preemptive rights offerings



Under Mexican law, if we issue new shares for cash as part of a capital increase, we generally must grant our shareholders the right to purchase a
sufficient number of shares to maintain their existing ownership percentage in Telmex. Rights to purchase shares in these circumstances are known as preemptive rights. We may not legally be permitted to allow holders of ADSs or holders of L Shares
or A Shares in the United States to exercise any preemptive rights in any future capital increase unless we file a registration statement with the U.S. Securities and Exchange Commission, or SEC, with respect to that future issuance of shares. At
the time of any future capital increase, we will evaluate the costs and potential liabilities associated with filing a registration statement with the SEC and any other factors that we consider important to determine whether we will file such a
registration statement.



7



---

##### Table of Contents

We cannot assure you that we will file a registration statement with the SEC to allow holders of ADSs or
U.S. holders of L Shares or A Shares to participate in a preemptive rights offering. As a result, the equity interest of such holders in Telmex may be diluted proportionately. In addition, under current Mexican law, it is not practicable for the
depositary to sell preemptive rights and distribute the proceeds from such sales to ADS holders.



Our bylaws restrict transfers of shares in some circumstances



Our bylaws provide that any acquisition or transfer of more than 10% of our capital stock by any person or group of persons
acting together requires the approval of our Board of Directors. If you wish to acquire or transfer more than 10% of our capital stock, you will not be able to do so without the approval of our Board of Directors.



Our bylaws restrict the ability of non-Mexican shareholders to invoke
the protection of their governments with respect to their rights as shareholders



As required by Mexican law, our bylaws provide that non-Mexican shareholders shall be considered as Mexicans in respect of their ownership interests in Telmex and shall be deemed to have agreed not to invoke the
protection of their governments in certain circumstances. Under this provision, a non-Mexican shareholder is deemed to have agreed not to invoke the protection of his own government by asking such government to interpose a diplomatic claim against
the Mexican government with respect to the shareholders rights as a shareholder, but is not deemed to have waived any other rights he may have, including any rights under the U.S. securities laws, with respect to his investment in Telmex. If
you invoke such governmental protection in violation of this agreement, your shares could be forfeited to the Mexican government.



Our bylaws may only be enforced in Mexico



Our bylaws provide that legal actions relating to the execution, interpretation or performance of the bylaws may be brought only in Mexican courts. As a
result, it may be difficult for non-Mexican shareholders to enforce their shareholder rights pursuant to the bylaws.



It may be difficult to enforce civil liabilities against us or our directors, officers and controlling persons



Telmex is organized under the laws of Mexico, and most of our directors,
officers and controlling persons reside outside the United States. In addition, a substantial portion of our assets and their assets are located in Mexico. As a result, it may be difficult for investors to effect service of process within the United
States on such persons or to enforce judgments against them, including in any action based on civil liabilities under the U.S. federal securities laws. There is doubt as to the enforceability against such persons in Mexico, whether in original
actions or in actions to enforce judgments of U.S. courts, of liabilities based solely on the U.S. federal securities laws.



Risks Relating to Developments in Mexico and Other Countries



Economic and political developments may adversely affect our business



Our business operations and assets are principally located in Mexico. As a result, our business may be significantly
affected by the general condition of the Mexican economy, by devaluation of the peso, by inflation and high interest rates in Mexico and by political developments in Mexico.

##### Table of Contents

Mexico has experienced adverse economic conditions



In the past, Mexico has experienced both prolonged periods of weak economic
conditions and deteriorations in economic conditions that have had a negative impact on our company. If the Mexican economy falls into a recession or if inflation and interest rates increase significantly, our business, financial condition and
results of operations could suffer material adverse consequences because, among other things, demand for telecommunications services may decrease and consumers may find it difficult to pay for the services we offer.



Depreciation or fluctuation of the currencies in which we conduct
operations relative to the U.S. dollar could adversely affect our financial condition and results of operations



We are affected by fluctuations in exchange rates.



Changes in the value of the various currencies in which we conduct operations against the Mexican peso or changes in the value of the Mexican peso or the
various currencies in which we conduct operations against the U.S. dollar may result in exchange losses or gains on our indebtedness and accounts payable. At December 31, 2004, our U.S. dollar-denominated indebtedness amounted to P.75,718 million.
In 2004, the peso depreciated against the U.S. dollar at year-end by approximately 0.3%, but our loss in Mexico was more than offset by a gain at our non-Mexican subsidiaries, particularly Embratel Participações S.A. As a result, we
had a net foreign exchange gain of P.26 million. In 2003, the peso depreciated against the U.S. dollar at year-end by approximately 9.0% and we had a net exchange loss of P.3,296 million. In addition, currency fluctuations between the Mexican peso
and the currencies of our non-Mexican subsidiaries affect our results as reported in Mexican pesos. Currency fluctuations may continue to affect our financial income and expense and our revenues from international settlements.



Major devaluation or depreciation of any such currencies may also result in
disruption of the international foreign exchange markets and may limit our ability to transfer or to convert such currencies into U.S. dollars and other currencies for the purpose of making timely payments of interest and principal on our
indebtedness. While the Mexican government does not currently restrict, and for many years has not restricted, the right or ability of Mexican or foreign persons or entities to convert pesos into U.S. dollars or to transfer other currencies out of
Mexico, the government could institute restrictive exchange rate policies in the future.



High levels of inflation and high interest rates in Mexico could adversely affect our financial condition and results of operations



Mexico has experienced high levels of inflation and high domestic interest rates. The annual rate of inflation, as measured
by changes in the National Consumer Price Index, was 5.2% for 2004. Inflation for the first quarter of 2005 was 0.79%. If Mexico experiences high levels of inflation, our profitability could be adversely affected, and more generally, high inflation
might result in lower demand or lower growth in demand for telecommunications services.



Developments in the U.S. economy may adversely affect our business



Economic conditions in Mexico are heavily influenced by the condition of the U.S. economy due to various factors, including commercial trade pursuant to
the North American Free Trade Agreement, or NAFTA, U.S. investment in Mexico and emigration from Mexico to the United States. Events and conditions affecting the U.S. economy may adversely affect our business, results of operations, prospects and
financial condition.

Developments in other emerging market countries may adversely affect the market price of our
securities



The market value of securities of Mexican
companies is, to varying degrees, affected by economic and market conditions in other emerging market countries. Although economic conditions in such countries may differ significantly from economic conditions in Mexico, investors reactions to
developments in any of these other countries may have an adverse effect on the market value of securities of Mexican issuers. In late October 1997, prices of both Mexican debt securities and Mexican equity securities dropped substantially,
precipitated by a sharp drop in value of Asian markets. Similarly, in the second half of 1998, prices of Mexican securities were adversely affected by the economic crises in Russia and in Brazil. There can be no assurance that the market value of
our securities would not be adversely affected by events elsewhere, especially in emerging market countries.



Political events in Mexico could adversely affect Mexican economic policy and our operations



The national elections held in July 2000 ended 71 years of rule by the
Institutional Revolutionary Party, or PRI, with the election of President Vicente Fox, a member of the National Action Party, or PAN, and resulted in the increased representation of opposition parties in the Mexican Congress and in mayoral and
gubernatorial positions. There has been a lack of alignment between the legislature and the President that has resulted in deadlock and has prevented the timely implementation of legislative and economic reforms, which some believe has had an
adverse impact on the Mexican economy and is expected to continue at least until the Mexican presidential elections in 2006. Further delays may continue to adversely affect the Mexican economy and our business.



Developments in other Latin American countries in which we operate may
affect our business



We have expanded our operations
through our investment in telecommunications companies and our acquisition of telecommunications assets in Brazil, Chile, Argentina, Peru and Colombia. These countries expose us to different or greater country risk than Mexico. Our future results
may be affected by the economic and financial condition of the countries in which we operate, the devaluation of the local currency, inflation and high interest rates, or political developments, changes in law or changes in labor conditions.
Devaluation of the local currency against the U.S. dollar may increase the operating costs in that country, and a depreciation against the Mexican peso may negatively affect the results of our operations in that country.

Item 4. Information on the Company



GENERAL



Overview



We own and operate the largest telecommunications system in Mexico, where we
are the only nationwide provider of fixed-line telephony services and the leading provider of fixed local and long distance telephone services. We also provide other telecommunications and telecommunications-related services such as corporate
networks, Internet services, directory services, information network management, telephone equipment sales, interconnection services to other carriers and paging services. Since February 2004, we have offered voice, data and Internet services in
Brazil, Chile, Argentina, Peru and Colombia.



In Mexico, we
have developed a multi-service network in which 90% of the lines have the capacity to provide simultaneous transmission of voice and data through a broadband connection. We have facilitated access to our network through new services such as Prodigy
Móvil, which offers Wireless Fidelity, or Wi-Fi, access in over 50 cities. At the same time, we are extending our telephone and Internet services to remote areas. In 2004, we obtained a major part of the Fondo de Cobertura
Social, through which we will provide basic telephone services to 4,000 rural towns throughout Mexico, and through e-Mexico, we are participating in a government-sponsored program that will extend e-learning, e-health, e-government and
e-commerce services via satellite to over 4,000 community digital centers in over 3,200 towns.



For our lower income customers and customers who need to control their telephone expenses, our Multifon service offers a telephone line without requiring payment of a monthly fee. By the end of 2004, the
service gave more than one million customers the ability to access voice and Internet services using a prepaid phone card. We also offer prepaid cards for use in public telephones and a discounted Internet access plan for use during off-peak hours.



Outside Mexico, we have focused on restructuring and

Local Service



Our network included 17.2 million local fixed lines in service at December 31, 2004, an increase of 9.5% compared to December 31, 2003, reflecting 2.2
million new lines and 712 thousand disconnections in 2004. Local traffic in 2004 increased by 0.6% compared to 2003, for a total of 26,782 million calls. The increase in billed traffic in 2004 was attributable primarily to the increase in lines in
service, the increased use of Telmex Voice Mailbox (Buzón Telmex) and the growth of digital services.



Our network is 100% digital, with all of our lines connected to digital exchanges. During 2004, customers made increasing use of digital services, such as
caller ID, call waiting, three-way calling, call forwarding and voicemail. The number of lines with digital services in use at year-end 2004 was 6.6 million (38.2% of the total number of lines in service), representing an increase of 3.2% from 2003.
This increase was due largely to an increase in new lines.



We
provide local telephone service to 21,596 communities throughout Mexico. Lines in service are concentrated in large urban areas. Of all lines in service, 40% are in the Mexico City, Monterrey and Guadalajara areas, and 29.1% are in the Mexico City
area alone. We provide service to 12,640 rural communities, exceeding our obligations to extend services to rural areas.

Our charges for fixed-line local telephone service include (a) installation charges, (b) monthly line
rental charges, (c) monthly measured service charges, (d) digital services and (e) charges for other services, such as the transfer of a line to another address and reconnection. Residential customers pay a fixed charge per local call in excess of a
monthly allowance of 100 local calls, and commercial customers pay for every local call at the same fixed rate per call. We estimate that in any given month approximately 56% of residential customers made fewer than 100 local calls per month on
average in 2004. The concession we hold to operate a public network for basic telephone services (the Concession) permits but does not require us to base our charges on the duration of each call, with a monthly allowance of free calls or call
minutes for residential customers. We currently do not charge by duration of invoiced calls in any region, except in the case of prepaid services.



In 2004, to promote local service among our commercial customers we introduced a plan called Business Line
(Línea Negocio), for which we charge a monthly line rental fee, which includes a monthly allowance of 200, 500 or 1,000 calls.



We offer prepaid local and long distance service through our Ladatel and Multifon calling cards. Multifon cards, originally
developed for use with public phones and invoiced fixed-line phones, are now available for our Multifon residential lines. Multifon Home offers prepaid local and long distance service on home telephones. For a total cost of P.1,000, Multifon Kit
provides installation, a handset and an initial P.100 of airtime for calls to the United States and Canada. In the case of our Multifon products, customers do not pay monthly fees, and prepaid fixed-line service is charged on a per-minute basis like
public telephony services. At December 31, 2004, Multifon lines totaled 1,187,593, an increase of 85.8% compared to December 31, 2003.



In October 2004, we announced that we would not increase rates for local telephone service during 2005. No rate increases have been made since March 2001,
when we increased our monthly line rental charges for residential customers by 6.5% and monthly measured service charges for all customers by 6.4% (in each case, in nominal terms).



Domestic Long Distance Service



We are the leading provider of domestic long distance telecommunications services in Mexico. Our domestic long distance transmission network consists of
close to 75,000 kilometers of optical fiber connecting Mexicos major cities, and includes secondary branches and an additional transmission ring around Mexico City designed to avoid network congestion.



Our charges for domestic long distance service are based on call duration and
the type of service, i.e., direct-dial or operator-assisted. In October 2004, we announced that we would not increase our nominal rates for domestic long distance service in 2005. Our nominal rates for domestic long distance service have remained
unchanged since March 1999.



We offer a variety of domestic
long distance discount plans that reduce the effective rates paid by our customers based on volume, time of use or other factors. High volume corporate clients pay P.1.00 per minute, which represents a discount of up to 55.9% from our nominal rate,
while other customers that maintain service with us receive discounts of up to 39%, as well as a 50% discount on calls made between 8:00 p.m. and 7:59 a.m. from Monday to Saturday and all day Sunday. In 2003, we introduced Lada 100, a
service that offers a monthly package of 200 domestic long distance minutes for P.100.

International Long Distance Service



We are the leading provider of international long distance telecommunications services in Mexico. International long
distance traffic with the United States, Canada, Central America and other countries is carried by a combination of the fiber optic network, microwave transmission, satellite systems and submarine cable. See Network.



Charges for international long distance calls are based on type of service,
call duration and the region of the world called. In October 2004, we announced that we would not increase our nominal rates for international long distance service in 2005. Our nominal rates for international long distance service have remained
unchanged since March 1999. Customers receive a 33.3% discount on calls made to the United States and Canada between 7:00 p.m. and 6:59 a.m. from Monday to Friday, all day Saturday, and between 12:00 a.m. and 4:59 p.m. on Sunday. More recently, we
have introduced Favorite Lada Destinations (Lada Favorito), a plan offering discounts on calls to cities in the United States pre-selected by customers. In July 2004, we launched Lada 100 International, which offers
100 minutes per month to the United States and Canada for P.200.



Bilateral agreements with foreign carriers govern the rates of our payment to foreign carriers for completing international calls from Mexico and by foreign carriers to us for completing international calls to Mexico. The rates of payment
under such agreements are negotiated with each foreign carrier. Settlements among carriers are normally made monthly on a net basis. Settlement amounts payable to us in respect of calls from the United States to Mexico generally exceed amounts
payable by us in respect of calls from Mexico to the United States. As a result, we receive monthly net settlement payments from U.S. carriers. We make monthly net settlement payments to other international carriers taken as a whole.



The international settlement rates that U.S. carriers pay to foreign carriers
have been subject to intense downward pressure due to competition and regulatory factors, including initiatives by the United States government. Since 1999, there has been a cumulative reduction of 75.5% in our settlement rates with U.S. carriers.
Until July 2004, Mexican regulations required that (i) all carriers pay the same rates, (ii) incoming international calls be distributed among the Mexican carriers in proportion to the outgoing calls they originated and (iii) the Mexican carrier
with the largest market share on a particular international route negotiate rates for all Mexican carriers on that route.



In 2004, we paid U.S.$0.037 per minute for northbound (Mexico to the United States) calls and received an average rate of U.S.$0.059 per minute for
settling international calls compared with an average rate of U.S.$0.099 per minute in 2003.



We are in the process of negotiating with most of the U.S. carriers new settlement rates for the period beginning January 1, 2005.



We believe that our international traffic volume has been adversely affected by an unauthorized practice in Mexico referred
to as illegal bypass. In the past, companies engaged in illegal bypass because international settlement rates to terminate traffic in Mexico were generally higher than rates for terminating domestic Mexican long distance traffic. The
unreported international traffic negatively impacted our revenues by diminishing both the settlement payments we received and our share of the proportional return on incoming traffic. We believe that illegal bypass was primarily responsible for the
decline in the number of minutes of our international long distance traffic from 2000 to 2003.



In August 2004, however, Mexico eliminated its uniform settlement rate system, its proportional return system and its requirement that the Mexican carrier with the greatest share of outgoing traffic to a particular
country negotiate the settlement rate on behalf of all Mexican carriers for that country. Because each Mexican carrier is now free to negotiate settlement rates with each foreign carrier, this form of bypass has disappeared.

##### Table of Contents

Our results are increasingly affected, however, by a practice we call local bypass, in which incoming
international calls are routed from domestic long distance carriers to local lines other than ours and then connected to our local network for termination. As a result of Mexicos bill and keep system, which provides that local
carriers do not pay interconnection fees to other local carriers, we do not receive an interconnection fee from these calls. But for local bypass, we would receive a domestic termination fee for completing these incoming calls. Though we have agreed
with most local carriers to request regulatory intervention to eliminate illegal local bypass, we believe our interconnection results will continue to be adversely affected by this practice.



Our international long distance revenues are also affected by VoIP
technology, which transmits ordinary telephone calls over the Internet. Because calls made through VoIP services bypass our network, we receive neither the interconnection fees nor the termination fees associated with calls made through traditional
fixed-line telephony services. Domestic long distance and local revenues are also affected by VoIP technology.



Interconnection



We
provide interconnection service pursuant to which (a) long distance, local and cellular carriers operating in Mexico establish points of interconnection between their networks and our network and (b) we carry calls between the points of
interconnection and our customers. When a customer of another carrier calls a local service customer of ours, we complete the call by carrying the call from the point of interconnection to the particular customer, and when a local service customer
of ours who has preselected a competing long distance carrier makes a long distance call, we carry the call from the customer to the point of interconnection with the relevant carriers network. We have one rate for interconnecting all
categories of carriers and all types of calls.



Corporate Networks



Corporate networks consist of the transmission of voice,
video and data between two or more end points using private or virtual circuits. During 2004, the number of line equivalents provided by means of corporate networks increased by 33.2%, to 1,517 thousand. Our principal product offerings for corporate
networks are Ladalinks (Ladaenlaces), Frame Relay and Internet through Internet Protocol / Multi-Protocol Label Switching, or IP/MPLS. Using equipment installed on-site, Ladalinks customers have dedicated network links that
transmit information at speeds ranging from 64 Kbps to 622 Mbps. IP/MPLS is a multi-service platform that allows us to provide integrated voice, data and video services, along with Next Generation VoIP services. Frame Relay is a protocol for
transmission of data, voice and video over a shared digital network. The speed of Frame Relay transmission ranges from 64 Kbps to 2,048 Kbps. Ladalinks and Frame Relay offer extensive technical assistance and customer support. In addition, we
provide networks outsourcing, including network maintenance and support, to major institutions and private companies. We also provide hosting and co-location products, as well as telecommunications network integration services and information
systems.



Internet Services



Internet services connect both business and residential customers to the
Internet through either a dedicated or dial-up connection. In 2004, the number of Internet customers increased to 1,741 thousand, an increase of 19.9% compared with 2003. Business and residential customers connect to the Internet using telephone
lines or broadband connections. We estimate that we are the leading Internet access provider in Mexico in terms of number of subscribers. As of March 31, 2005, the number of Internet service subscribers was 1,855 thousand, compared with 1,521
thousand as of March 31, 2004, representing an increase of 21.9%.

Our broadband service, Prodigy Infinitum, makes it possible for customers to use our high-capacity
connectivity services with applications such as video-conferencing, file transfer, terminals, e-mail and protocol conversion. Prodigy Infinitum operates over asymmetric digital subscriber line, or ADSL, technology. In March 2004, we launched the
Prodigy Infinitum kit, which provides our customers with all the equipment necessary to set up their own service. At year-end 2004, we had 560 thousand customers using our ADSL broadband services, an increase of 212.5% over 2003. We further expanded
our broadband offerings with the launch of Prodigy Mobile (Prodigy Móvil), a high-speed wireless connection for residential and business customers that connects users to the Internet at speeds up to 11 Mbps at a range that
extends 20 and 100 meters. As of December 31, 2004, we also provided 388 public hot spots in 58 cities in Mexico at which our clients could obtain wireless access to the Internet.



Prodigy Internet Plus provides a customer with a multi-media personal
computer, a personal web page, an e-mail account and two years of unlimited access time for a fixed monthly price. This program accounted for 149 thousand subscribers in 2004, or 12.8% of the total number of Internet access account subscribers at
year-end. Our Prodigy Home (Prodigy Hogar) package, for a lower fixed monthly price than Prodigy Internet Plus, provides customers with a basic personal computer, a personal web page, an e-mail account, three years of unlimited
Internet access during off-peak hours and billed access on a per-minute basis during peak hours.



Consistent with our strategy of providing value-added services to maximize the value of residential and business Internet accounts, we introduced two new
services in 2004: (i) Prodigy Home with a reduced monthly fee, which provides customers with unlimited Internet access between 6:00 p.m. and 8:00 a.m. from Monday to Friday plus the entire weekend and access for P.0.13 per minute at all other times
and (ii) a new Multifon Card function, which allows customers who do not otherwise have Internet access to access the Internet with their Multifon Card for P.0.13 per minute. We also offer Prodigy Internet i-call, a service that notifies customers
of incoming calls, Prodigy Configuration (Configurador Prodigy), a service that provides traveling customers with a connection from anywhere in Mexico at the rate for local calls and Prodigy Patrol, a service that allows Prodigy
Internet, Prodigy Internet Plus and Prodigy Infinitum customers to limit access to certain web sites.



Other Services



We
provide various other telecommunications and telecommunications-related products and services, including printed and online yellow pages directories, public phones and prepaid cards and Internet portals and e-commerce for consumers and businesses.



Yellow Pages Directories



We offer both a printed and an Internet-based yellow pages directory. During
2004, our yellow pages web site averaged over seven million page views per month. The number of Internet directory users reached over 700 thousand per month in 2004.



Public Telephony and Prepaid Phone Cards



We have several programs to meet the need for different kinds of public telephone service in different areas. We had more
than 784 thousand fixed public telephones in operation at December 31, 2004. In the increasingly competitive market to provide telecommunications services, independent operators have installed public telephones for which we provide access. There
were 26,512 independently operated public telephones at December 31, 2004, an increase of 20.5% compared with 2003.

##### Table of Contents

In 2004, we sold over 247.5 million prepaid cards under the brand name Ladatel for use in
public phones and 25.5 million prepaid cards under the brand name Multifon for use in public and residential telephones, a decrease of 2.0% from 2003. This represents an average of almost 2.5 cards per Mexican resident. We have installed
Internet kiosks in public places so that our customers have access to Internet products and services by using Ladatel cards. Revenues from sales of prepaid cards (based on an estimate of usage) accounted for 5.3% of our consolidated revenues in
2004. In 2004, our revenues from public telephony decreased by 6.0% as a result of intense competition from wireless carriers.



Internet Portals and e-Commerce



In March 2000, we launched T1MSN, an Internet portal that is a 50-50 joint venture between Microsoft Corporation, or Microsoft, and us. T1MSN takes
advantage of Microsofts world-class technologies and our leading infrastructure, operations and regional knowledge to offer users a broad range of services and content in Spanish, such as easy and secure shopping services and enhanced
communication features.



We operate a web-based
service called Eficentrum, which is a horizontal business-to-business market for the indirect exchange of goods and services. The current volume of transactions has made Eficentrum the biggest horizontal portal in Mexico. We plan to implement other
new e-commerce initiatives in different market sectors, thereby continuing to broaden our range of services to the corporate sector.



Network



Our technologically advanced, high-capacity and high-speed, local and long distance fiber optic network, the largest in Mexico, extends approximately 82,700 kilometers, reaches 90% of Mexicos population and has
connections via submarine cables with 40 other countries while also connecting most major cities throughout Mexico. As a result of our substantial investment, our network has been 100% digital since 2000, providing a wide variety of telephony, data
and video services.



Our network includes digital switching
equipment and a digital network infrastructure that includes network access cables and domestic and long distance transmission equipment. In addition, we use advanced routing technology and routers to connect end-users with our network.



We use fiber optic cable to transmit both voice and high bandwidth
applications such as video and image data. For network access we use ADSL, a copper modem technology that uses existing phone lines to access the Internet at speeds of up to 10 megabits per second. The network is fully redundant and is supported by
fiber optic ground rings, which allow the network to be restored within 50 milliseconds in the event of a system failure. In addition, our digital microwave network serves as a backup to the fiber optic network and as a primary means of transmission
in rural areas and small towns where a fiber optic infrastructure is not available. We also have satellite systems that support domestic and international network traffic. In addition, in order to further boost transmission speeds, we use a
technology called Dense Wavelength Division Multiplexing, or DWDM, which divides optical fiber signals into multiple wavelengths and allows us to operate our network at speeds of up to 140 gigabits per second.

Core Network



Our core transmission network uses a technology called Next Generation Synchronous Digital Hierarchy, or Next Generation
SDH. Transmissions pass through a series of optic rings that give us the unique ability to protect information carried on the network from origin to destination. This level of protection is achieved through the rings self-repairing mechanism,
which prevents equipment and connection failures. This mechanism minimizes the risk of interruption of the signal in the event of any failure in the network.



Additionally, in our core transmission network we have introduced optical cross-connect technology, which is capable of transporting higher volumes of
traffic and protecting optical links with different self-recovery schemes to enhance network efficiency and allow for service differentiation.



Telephone communication in our network is controlled by digital local and long distance centers that employ a high degree of protection and load sharing.
We also rely on data management technology, which uses voice and data switches to manage large amounts of transmitted information in both our telephone and data networks. This technology also gives us the ability to develop and implement
advanced telephone applications in a short amount of time.



Our physical network comprises a combination of fiber optic, microwave and copper cable systems and wireless last-mile systems, which connect our clients to the network and allow us to provide our clients with
numerous applications and services. Our modernized external copper network is set up to support not only conventional telephone systems, but also modern broadband applications, which also rely on digital technology and result in high data
transmission speeds.



We control and monitor our networks
performance and traffic levels and manage the routing of traffic and other network functions through centralized network management. This centralized management facilitates geographical expansion of the network and permits the implementation of
higher capacity systems. Next Generation SDH technology gives us flexibility in the geographic placement of these switches and enables us to handle significantly more traffic with fewer switches than would a traditional non-digital
network.



Next Generation
Network



In the face of new
challenges arising from the globalization of telecommunications and the development of new technologies, we are transitioning our current network infrastructure to become a Next Generation Network. Our core transmission network uses Next Generation
SDH technology, and we are gradually integrating our service and data management systems under a unified network infrastructure with multi-service user ports that have the ability to integrate voice, data and video transmissions into one
standardized application. The Next Generation Network will allow us to improve flexibility in offering broadband services, increase efficiency in managing our network and improve the quality of our service.



As part of our transition to a Next Generation Network, we are deploying a
new network platform based on data packets, which will permit the creation of multi-service networks to carry different kinds of information in standardized formats. By utilizing such packet technology, we can provide superior local access, network
connectivity, data transmission and bandwidth delivery.



As of December 31, 2004, our cumulative investment in the Next Generation Network totaled U.S.$570 million. We have budgeted approximately U.S.$310 million for investment in our Next Generation Network infrastructure.

Billing and Customer Service



For corporate customers, we offer SI@NA, an Internet service that permits customers to analyze their telecommunications
spending. Residential customers may also access billing information over the Internet using the Telmex on-line (Telmex en Línea) service. We provide our customers with a bill format that details their local service usage.



We provide customer service through a network of customer
service centers and call centers. These customer service centers have evolved from their traditional purpose as places for payment to become Telmex stores that offer telecommunications products and services. Large corporate customers also receive
customer service from dedicated customer service personnel. Through our Integrated Solutions (Solución Integral) service, we assist corporate customers in meeting their telecommunications needs by providing them with
integrated telecommunications solutions consisting of a broad range of telecommunications services. We offer service level agreements to corporate customers that set service standards and guarantee continuity of service.



Competition



The Mexican market for fixed-line domestic and international long distance services was opened to competition beginning in
1996. Thirty-three carriers have been granted licenses to provide long distance service in Mexico, 14 of which are in operation. Alestra (a joint venture led by Alfa, S.A. de C.V., Grupo Financiero BBVA Bancomer, S.A. de C.V. and AT&T Corp.) and
Avantel (a joint venture led by Grupo Financiero Banamex and MCI) have made the most substantial investments in infrastructure and marketing. Most competing carriers have been principally focused on the long distance market, although some carriers
also provide certain business customers with direct access to their long distance networks using lines leased from us.



The Communications Ministry (Secretaría de Comunicaciones y Transportes) has established rules for the determination of interconnection
rates between our competitors and us. If we are unable to agree with our competitors on interconnection rates, Cofetel imposes the rates. During the last five years, however, we have agreed on these rates with our long distance competitors. We
agreed with our long distance competitors to maintain the same interconnection rates for 2004 and 2005 that have applied since 2002.



Customers are free to choose a competing carrier at any time. An independent organization confirms all requests to change long distance carriers. In
addition to pre-subscription, customers eventually may be able to select a long distance carrier on a call-by-call basis by dialing a three-digit prefix. In general, our competitors have focused their attention on obtaining market share in
Mexicos most profitable markets, such as the major cities and high-volume users of international and domestic long distance.



Competition in the Mexican market for fixed-line local services began in 1999. As of December 31, 2004, 18 carriers have been granted licenses to provide
local fixed wire and wireless telephony and 23 carriers have been granted licenses for cellular and mobile telephony. The 23 carriers are owned by only four companies: Radiomóvil Dipsa, S.A. de C.V., or Telcel, Telefónica
Móviles México, S.A. de C.V. and sister companies Grupo Iusacell, S.A. de C.V. and Unefon, S.A. de C.V. At present, there are 11 competitive local operators, primarily in Mexico City and other large cities. Avantel, Axtel and Maxcom
are our principal fixed-line competitors. To date, our competitors in local service have focused on servicing first-time customers and providing second lines in new housing, as well as inducing our customers to switch carriers.

##### Table of Contents

The competitive environment in the Mexican telecommunications market has been the subject of controversy
and of attention from Mexican regulators and from abroad. See RegulationCompetition.



The effects of competition on us depend, in part, on the business strategies of competitors, regulatory developments, exchange rates and the general
economic and business climate in Mexico, including demand growth, interest rates and inflation. The effects could include loss of market share and pressure to reduce rates for our services.



During December 2004, we estimate our market share in Mexico to be 79.4% in
domestic long distance service and 77.6% in international long distance service measured on the basis of total number of billed minutes generated by our local customers making domestic and international long distance calls in cities open to
competition. Our market share in Internet access is estimated to be 52.3% of dial-up connections, measured on the basis of the total number of Internet access accounts in Mexico. We believe that, at present, competitors do not have a material share
of the market for fixed-line local service, but we expect that this will change as the number of competitors grows and their market strategies develop. In local service and public telephony, we also face competition from cellular carriers, which we
estimate had a combined total of 38.4 million cellular lines in service at year-end 2004. We anticipate continued intense competition as mobile carriers promote mobile-to-mobile calls as a cheaper alternative to fixed-to-mobile calls. We also face
increasing competition in international and domestic long distance and local services from VoIP, a technology that transmits ordinary telephone calls over the Internet at a cost lower than that associated with traditional fixed-line telephony
services.



Regulation



Our business is subject to comprehensive regulation and oversight by the
Communications Ministry and Cofetel. The Communications Ministry is part of the executive branch of the Mexican federal government, and Cofetel is an agency of the Communications Ministry. Regulation and oversight are governed by the Law of General
Means of Communication (Leyde Vias Generales de Comunicación, or the General Communications Law), the Telecommunications Regulations adopted under such law, the Federal Telecommunications Law (Ley Federal de
Telecomunicaciones), the Concession and other concessions and license agreements granted by the Communications Ministry. We are also subject to oversight by the Agency of Consumer Protection (Procuraduría Federal del Consumidor)
and Antitrust Agency (Comisión Federal de Competencia).



Set forth below is a summary of certain provisions of the General Communications Law, the Federal Telecommunications Law, the Telecommunications Regulations and our concessions.



General



The General Communications Law, the Federal Telecommunications Law and the
Telecommunications Regulations provide the general legal framework for the regulation of telecommunications services in Mexico. The Federal Telecommunications Law replaced most of the provisions of the General Communications Law relating to
telephone communications, but those provisions of the General Communications Law not specifically addressed in the Federal Telecommunications Law, such as rules governing local and long distance carriers, remain in effect. Regulations implementing
particular provisions of the Federal Telecommunications Law have been issued by the Communications Ministry and Cofetel. Regulations implementing other provisions of the Federal Telecommunications Law are pending. The objectives of the Federal
Telecommunications Law are to promote the efficient development of the telecommunications industry, to encourage fair competition in the provision of quality, low-priced services and to assure satisfactory breadth of coverage of the Mexican
population.

##### Table of Contents

In October 2001, the Mexican Congress announced the beginning of a process to reform the Federal
Telecommunications Law. Some of the proposals that have been discussed, such as strengthening the regulatory power of Cofetel, stimulating increased investment in telecommunications and increasing competition, could have a material effect on our
operations.We are unable to predict whether or when such amendments may be implemented and, if implemented, their effect on our business.



Regulatory Oversight



The Communications Ministry is the Mexican government agency principally responsible for regulating telecommunications services. The Communications
Ministrys approval is required for any change in our bylaws. It also has broad powers to monitor our compliance with the Concession, and it may revoke our Concession or temporarily seize or expropriate our assets. The Communications Ministry
may require us to supply it with such technical, administrative and financial information as it may request.



The Federal Telecommunications Law provided for the establishment of an administrative agency, Cofetel, to regulate the telecommunications industry.
Cofetel commenced operations in August 1996. It is an independent agency within the Communications Ministry, with four commissioners appointed by the Communications Ministry on behalf of the President of Mexico, one of whom is appointed as chairman.
Many of the powers and obligations of the Communications Ministry under the Federal Telecommunications Law and the Telecommunications Regulations have been delegated to Cofetel. We regularly provide reports to Cofetel on our operations, financial
performance and other matters. We are also required to publish our annual network expansion program, and we must advise Cofetel of the progress of our expansion program on an annual basis.



Mexican law gives certain rights to the Mexican government in its relations
with concessionaires and provides that when the concession expires we may not sell or transfer any of our assets unless we give the Mexican government a right of first refusal. If the Mexican government declines to exercise its right, our unions
also have a right of first refusal. In addition, Mexican law permits the Mexican government to expropriate our assets in certain circumstances.



Concessions



Under the Federal Telecommunications Law and the Telecommunications Regulations, a provider of public telecommunications services must operate under a
concession granted by the Communications Ministry. Such a concession may not be transferred or assigned without the approval of the Communications Ministry. A concession to provide public fixed-network local and long distance services has a term for
up to 30 years and may be extended for additional 30-year terms. Our Concession was granted in 1976 and amended in August 1990, and will expire in 2026. Our subsidiary Telnor holds a separate concession in two states in northwestern Mexico, which
will expire in 2026. The material terms of the Telnor concession are essentially the same as the Concession.



Operators of private networks that do not use electro-magnetic frequencies are not required to obtain a concession to provide private telecommunications
services but are required to obtain approval from the Communications Ministry.



In addition to the Concession, we currently hold concessions for the use of frequencies to provide wireless local access and point-to-point and point-to-multipoint transmission, which we obtained from Cofetel through
a competitive bidding process. These concessions are granted for a term up to 20 years and may be extended for additional 20-year terms.

Termination of the Concession



The Concession provides that it will remain in force until 2026 and that we
may renew it for an additional 15 years, subject to additional requirements the Communications Ministry may impose. Thereafter, it may be renewed for successive 30-year terms as provided under the Federal Telecommunications Law.



The Concession provides that upon its expiration the Mexican government is
entitled to purchase our telecommunications assets at a price determined on the basis of an appraisal by a public official, and the Telecommunications Regulations provide that upon expiration of the Concession the Mexican government has a right of
first refusal to acquire our telecommunications assets. The General Communications Law, however, provides that upon expiration of the Concession our telecommunications assets will revert to the Mexican government free of charge. There is substantial
doubt as to whether the provisions of the Concession and the Telecommunications Regulations would prevail, and accordingly there can be no assurance that upon expiration of the Concession our telecommunications assets would not revert to the Mexican
government free of charge.



The General Communications Law and
the Concession include various provisions under which the Concession may be terminated before its scheduled expiration date. Under the General Communications Law, the Communications Ministry may cause early termination of the Concession in certain
cases, including:



| |  |  | failure to expand telephone services at the rate specified in the Concession;
| | - |  | -----------------------------------------------------------------------------



| |  |  | interruption of all or a material part of the services provided by us;
| | - |  | ----------------------------------------------------------------------



| |  |  | transfer or assignment without Communications Ministry approval of the Concession, the rights provided under the Concession or any asset used to provide telephone service;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | violation of the prohibition against ownership of our shares by foreign states;
| | - |  | -------------------------------------------------------------------------------



| |  |  | any material modification of the nature of our services without prior Communications Ministry approval; and
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | breach of certain other obligations under the General Communications Law.
| | - |  | -------------------------------------------------------------------------



In addition, the Concession provides for early termination by the Communications Ministry following administrative proceedings in the event of:



| |  |  | a material and continuing violation of any of the conditions set forth in the Concession;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | material failure to meet any of the service expansion requirements under the Concession;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | material failure to meet any of the requirements under the Concession for improvement in the quality of service;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | engagement in any telecommunications business not authorized under the Concession and requiring prior approval of the Communications Ministry;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | following notice and a cure period, failure without just cause to allow other concessionaires to interconnect their telephone networks to our telephone network; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our bankruptcy.

Under the Federal Telecommunications Law, our concessions could be terminated if: (i) the term of any
concession expires; (ii) we resign our rights under any concession; (iii) the Mexican Government through the Communications Ministry expropriates any of the concessions; (iv) we are liquidated or become bankrupt; or (v) the Communications Ministry
revokes any of the concessions. Our assets and rights under the concessions may also be temporarily seized by the Communications Ministry.



The General Communications Law provides that in the event of early termination of the Concession for specified causes, including violation of the
prohibition on ownership of our shares by foreign states, we would forfeit all of our telecommunications assets to the Mexican government. In the event of early termination of the Concession for any other cause, the General Communications Law
provides that a portion of our telecommunications assets would revert to the Mexican government free of charge, and that we may be required to dismantle the remaining portion. There is substantial doubt as to whether the provisions of the Concession
and the Telecommunications Regulations regarding the consequences of expiration of the Concession would apply to mitigate the provisions of the General Communications Law in the event of early termination.



Dominant Carrier Regulations



The Federal Telecommunications Law provides that if a company is determined
to be dominant in a relevant market, the Communications Ministry has the power to adopt specific regulations on rates, quality of service and information provided by a dominant provider. In February 1998, the Mexican Competition Commission, or MCC,
issued a resolution confirming its determination that we are a dominant carrier in the following markets: (i) local telephone service, (ii) access service, (iii) inter-urban transport, (iv) domestic long distance service and (v) international long
distance service. This 1998 resolution was held unconstitutional in May 2001.



In September 2000, Cofetel adopted specific regulations, which we refer to as the dominant carrier regulations, applicable to us as a dominant carrier. The September 2000 Cofetel resolution to adopt these regulations
was nullified in May 2002. The dominant carrier regulations applied to the five markets identified by the MCC in 1998, and also to certain other services, including directory assistance, operator services and billing and collection services. They
imposed standards for the quality of our services, and required that we prepare and provide specific information and specific tariff regulations. We have met or exceeded the standards established in the former regulations on quality of services and
on information, and we believe we will be able to continue doing so without significant cost or competitive impact.



The most significant elements of the dominant carrier regulations were the following three specific rules on tariffs:



| |  |  | First, our prices for covered services must always exceed a floor price based on total average costs. The Concession says our price for any service must exceed the
average incremental cost, and while the methodology for determining total average costs is not clear, it would presumably result in a higher floor price for the services to which it applies.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Second, the regulations prohibit any rate or rate package that reduces our operating margin in a competitive market, except as a defensive response to competitors rates that
present a risk of substantial loss of market share.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Third, prices for services (other than interconnection) that we provide to other carriers would, for the first time, be subject to prior approval of Cofetel.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

It is difficult to assess the impact these regulations would have had on tariffs or competition, in part
because neither the methodologies nor the procedures were fully specified. We believe, however, that if similar rules were implemented in the future, they would, to some degree, reduce our flexibility to adopt competitive tariff policies.



After the MCC issued the February 1998 resolution, we
commenced constitutional proceedings in the Mexican federal courts challenging the validity of the resolution, and we commenced a proceeding in the Mexican federal courts challenging the validity of the dominant carrier regulations. We asserted that
they constituted a unilateral amendment of the terms of our Concession, which we believe is not permitted under the Mexican constitution or the terms of the Concession itself. We also asserted that the determination that we are a dominant carrier,
on which Cofetels power to issue these regulations was predicated, was flawed because the MCC made its determinations in 1997 in reliance on earlier findings that were out of date, and because its determinations did not extend to all the
markets covered by the dominant carrier regulations. Finally, we objected to the specific tariff regulations imposed by the dominant carrier regulations on a variety of grounds, including that they gave Cofetel excessive discretion, that they would
unfairly burden competition and that they did not adequately permit us to recover our investments in infrastructure.



Following several appeals, the February 1998 resolution of the MCC was held unconstitutional in May 2001. It is our assertion that all subsequent rulings
by Mexican government agencies (including Cofetel) that relied upon the 1998 resolution are also unconstitutional. We filed petitions to have dominant carrier regulations based on the 1998 resolution declared unconstitutional, and in May 2002,
several resolutions issued by the MCC and Cofetel were nullified, including the September 2000 Cofetel resolution adopting the dominant carrier regulations.



In May 2001, the MCC addressed the defect of the February 1998 resolution and issued a new resolution with the same terms in which it concluded that we
are a dominant carrier in the same five markets. This resolution was affirmed by the MCC following an appeal, and in September 2001, we commenced constitutional proceedings in the Mexican federal courts challenging the validity of this new
resolution. In July 2003, a Mexican federal court held that certain aspects of the MCCs second dominant carrier resolution were invalid, although the MCC sought further review. In April 2004, a Mexican federal court decided in favor of our
constitutional challenge to the resolution and declared the resolution invalid. In September 2004, the MCC issued additional resolutions in which it again concluded that we are a dominant carrier, and in October 2004, we again commenced
constitutional proceedings in the Mexican federal courts challenging the validity of the new resolutions. We cannot predict whether our constitutional challenge will be successful or if it is successful whether the MCC or Cofetel will issue new
resolutions or regulations that are substantially similar to the prior dominant carrier resolutions or regulations that were nullified.



Rates



The General Communications Law, the Federal Telecommunications Law and the Telecommunications Regulations provide that the basis for setting rates of a
telecommunications concessionaire is set forth in its concession.



Under the Concession, our rates in any period for basic telephone services, including installation, monthly rent, measured local service and long distance service, are subject to a ceiling on the price of a basket of such
services weighted to reflect the volume of each service provided by us during the preceding period. There is also a price floor based on our average long run incremental cost. Within this aggregate price cap, we are free to determine the structure
of our own rates. We must publish our rates and register them with Cofetel before they may take effect.



27



---

##### Table of Contents

The price cap varies directly with the Mexican National Consumer Price Index, permitting us to raise
nominal rates to keep pace with inflation, subject to consultation with the Communications Ministry. Since the beginning of 2001, we have not raised our nominal rates. Under the Concession, the price cap is also adjusted downward periodically to
pass on the benefits of increased productivity to our customers. The Concession fixed the adjustment for 1998 and 1999 at 0.74% per quarter in nominal terms, and requires the Communications Ministry to set a new periodic adjustment for every
four-year period so as to permit us to maintain an internal rate of return equal to our weighted average cost of capital. The Communications Ministry fixed the adjustment per quarter in nominal terms at 1.11% for 1999-2002 and at 0.74% for
2003-2006.



For services extending beyond basic telephone
service, under the Concession we are permitted to set our prices free of rate regulation. These services include data transmission, directory services and services based on digital technology, such as caller ID, call waiting, speed calling,
automatic redialing, three-way calling and call forwarding. We are required to register the rates of value-added services on an annual basis.



Competition



The Telecommunications Regulations and the Concession contain various provisions designed to introduce competition in the provision of communications
services. In general, the Communications Ministry is authorized to grant concessions to other parties for the provision of any of the services provided by us under the Concession. There are currently 14 competing long distance carriers operating in
Mexico and concessions have been granted to a total of 33 long distance companies, all of which also have concessions for international long distance services. As of December 31, 2004, there were 18 fixed-line local operators that have been granted
licenses, primarily in Mexico City, Guadalajara, Monterrey, Puebla and other large cities. See Mexican OperationsCompetition. Concessions are not required to operate certain private local telecommunications networks or to provide
value-added services, although other authorizations may be required.



The Federal Telecommunications Law provides that the Communications Ministry may authorize the resale of telecommunications services. Though no regulations have yet been adopted implementing that provision of the law, we expect the Mexican
government to introduce new regulations regarding resale by the end of July 2005.



In 2003, the Communications Ministry expanded the concessions granted to cable television operators to permit them to provide bi-directional transmission of data. In addition, in 2004, the Communications Ministry
began to permit cable operators to provide signal-transmission services to local fixed-line operators and data and broadband Internet Services to the Mexican public. Our Concession permits us to distribute, with prior authorization,
television signals through our network to companies authorized to provide television services to the public, but we are not allowed to hold a concession to provide television signals to end users.



With respect to international long distance services, Cofetel rules cover
matters such as international interconnection and mechanisms for routing calls into and out of Mexico. Currently, international traffic must be carried by Mexican concessionaires and through authorized international gateways consistent with
Cofetels international long distance rules.



The
competitive environment in the Mexican telecommunications market has been the subject of controversy and of attention from Mexican regulators and from abroad. In particular, the MCC has determined that we are a dominant provider of certain
telecommunications services, though our appeal of this determination is pending. Mexican law provides for the regulatory authorities to impose additional regulations on a dominant provider. As discussed above, Cofetel has adopted specific
regulations



28



---

##### Table of Contents

applicable to us as a dominant carrier, although these regulations were later nullified by a Mexican federal court. The
MCC has repeatedly ruled that we have engaged in relative anti-competitive practices, which are less significant violations than absolute anti-competitive practices and carry lower fines. Most of these resolutions have been
declared null and void by federal courts or withdrawn by the MCC.



In August 2000, the United States initiated a World Trade Organization, or WTO, dispute settlement against Mexico regarding alleged illegal barriers to competition in the Mexican telecommunications market. The allegations related to our
status as a dominant telecommunications provider in Mexico and the interconnection fees and charging mechanisms for international calls.



On June 1, 2004, the United States and Mexico announced that they had mutually agreed to resolve the dispute. Under this agreement, Mexico eliminated its
uniform settlement rate system, its proportional return system and its requirement that the Mexican carrier with the greatest share of outgoing traffic to a particular country negotiate the settlement rate on behalf of all Mexican carriers for that
country. Mexico also agreed to introduce new regulations authorizing the resale of outgoing international long distance services in 2005. In addition, the United States recognized that Mexico will continue to restrict international simple resale, or
the use of leased lines to carry cross-border calls. We expect that the changes in regulation will likely affect our business and competition in the future, and in particular, that the authorization of resale of telecommunications services will put
downward pressure on the prices we charge our customers for those services.



Interconnection



We are required under the Federal Telecommunications Law to permit any other long distance concessionaire to connect to our network in a manner that enables customers to choose the network by which their long distance calls are carried.
Cofetel rules governing the interconnection rights and obligations of local service concessionaires require local service concessionaires to provide interconnection on a nondiscriminatory basis to any other concessionaire.



The Concession provides that other terms of interconnection, including fees,
are to be negotiated between us and each other long distance carrier, and that, in the event the parties are unable to agree, the Communications Ministry may impose terms on us and the other carriers. We were unable to agree with our competitors on
interconnection rates for 1997 through 2000, and accordingly Cofetel imposed rates. The interconnection fees imposed by Cofetel were the subject of numerous legal challenges. We also brought proceedings contesting our obligation to renew the
existing service agreements with competing carriers based on the new interconnection tariffs, on the grounds that the carriers had not honored the current agreements.



Since 2002, we have agreed with competing long distance carriers to an interconnection rate of U.S.$0.00975 per minute and
per interconnection point. This rate will apply through December 31, 2005.

NON-MEXICAN OPERATIONS



Through
our subsidiaries, we provide voice, data and Internet services in Brazil, Chile, Argentina, Peru and Colombia. The revenues of our non-Mexican operations represented 11.4% of our consolidated revenues for 2004. These operations derive from our
acquisition of AT&T Latin America Corp. in February 2004 for U.S.$196.3 million (with operations in all five countries), Techtel-LMDS Comunicaciones Interactivas, S.A. in April 2004, Chilesat Corp. S.A. and Metrored Telecomunicaciones S.R.L. in
June 2004 and Embratel in a series of transactions beginning in July 2004.



The following table sets forth selected financial information for the year ended December 31, 2004 expressed as a percentage of our total consolidated group. For our operations in Brazil and other countries outside
Mexico, all of which were acquired during 2004, the table includes financial information subsequent to the date of consolidation.

Brazil



Embratel Participações and Telmex do Brasil



Embratel Participações S.A., or
Embratel, and Telmex do Brasil Ltda. are our principal subsidiaries in Brazil.



Of our revenues from our Brazilian operations in 2004, over 70% was attributable to voice services, approximately 25% was attributable to data services and the remainder was attributable to other services. Voice
services include domestic and international long distance and local service. Data services include data and Internet services. Other services include the transmission of television and radio, telex and mobile satellite communications services.



We own 95.1% of the voting stock and 45.4% of the
non-voting stock of Embratel (63.9% of the total capital stock) as a result of a series of transactions in 2004 and 2005. In July 2004, we purchased 51.8% of the voting stock of Embratel from MCI for a cash purchase price of U.S.$400 million. We
purchased additional voting stock through a mandatory tender offer in December 2004 and both voting and non-voting stock in various subscriptions from March to May 2005 in Embratels approximately U.S.$700 million capital increase.



Through its subsidiaries, Embratel is one of the leading providers of
communications services in Brazil. Of its total revenues in 2004, approximately 57% were derived from corporate customers, and the remainder from residential customers. Its principal service offerings include domestic and international long
distance, data communications, local and other services. Through its high-speed data network, it

##### Table of Contents

offers a broad array of products and services to a substantial number of Brazils 500 largest corporations. Telmex
do Brasil provides telecommunications services to corporate customers in Brazils largest cities including Rio de Janeiro and São Paulo, complementing Embratels business in those cities.



The Brazilian domestic and international long distance markets are
increasingly open to full competition, and competitors have gained market share at Embratels expense and are placing pressure on its prices and competing for attractive customers in its long distance and data businesses. To respond, Embratel
is pursuing a marketing strategy to attract and retain customers and develop its customer base. Embratel is promoting price clarity, implementing win-back programs and tailoring marketing campaigns to each region.



Embratel was founded in 1965 and later became the long distance subsidiary of
Telebrás, the Brazilian government-owned telephone company. In 1998, Telebrás was broken up into 12 new holding companies, which were then privatized, including one holding company, Embratel, for the domestic and international long
distance operator. After the opening up of the Brazilian local service market, Embratel began providing local telephone services in 2002. In 2003, Embratel acquired Vésper Holding S.A. and Vésper Holding São Paulo and their
subsidiaries, wireless local loop local service and broadband data operators with operations in São Paulo and 16 other Brazilian states. Through its subsidiary Star One, Embratel is also Brazils leading provider of satellite services,
with applications including broadcasting, broadband data and telephony. Star One currently has four satellites in orbit, which cover the entire territory of Brazil as well as Argentina, Uruguay and Paraguay. Embratel expects to replace one of its
satellites in the second half of 2006 with a new satellite that will also provide coverage over South America, as well as part of Florida.



Embratel owns the largest long distance telecommunications network in Latin America and the largest network of broadband fiber optic transmission systems
in Brazil. The network, which connects all of the regional fixed-line and cellular operators throughout Brazil, uses a 100% digital switching system for voice and data and packet-switched data communications, asynchronous transfer mode, or ATM, and
frame relay for data and Internet services. The domestic long distance and international transmission facilities extend to all 26 states and the Federal District of Brazil and include fiber optic, digital microwave, satellite and copper wireline
networks.



Telmex do Brasils network extends to
seven major cities in Brazil and has points of presence, or POPs, for data and voice services in two other cities. POPs are nodes that are extensions of a network that permit access to customers in cities where a provider does not have metropolitan
networks. The network is based on fiber optic cable and like Embratels, uses primarily ATM transport technology.



Regulation



The Brazilian Telecommunications Law provides a framework for telecommunications regulation. Pursuant to Article 8 of the Telecommunications Law and
Decree No. 2,338 of October 7, 1997, the primary regulator of Embratel and Telmex do Brasil is Anatel.



Companies wishing to offer telecommunications services to consumers are required to apply to Anatel for a concession or an authorization. Concessions are
granted for services in the public regime and authorizations are granted for services in the private regime.



Embratels concession for the provision of long distance service is subject to certain obligations and is valid until 2005. Prior to its expiration
in 2005, the concession may be renewed for an additional 20 years. In the event that the concession is not renewed or is revoked by Anatel, all assets relating to the provision of services under the concession revert to the Brazilian government. In
June 2003, Anatel established the basic terms for the renewal of the concession contracts. Embratel formally notified Anatel of its intention to renew the concession contract on these terms, but the new concession contract has not yet been signed.



31

##### Table of Contents

The initial grant of the concession to Embratel did not require payment of a fee. After December 31,
2005, Embratel is required to pay a fee every two years equal to 2% of annual net revenues from the provision of switched fixed telephone services in the prior year (excluding taxes and social contributions). This requirement will last throughout
the 20-year renewal period.



Since the privatization of the
Brazilian telecommunications system, concessionaires have been required to meet certain universal service and quality targets. Failure to meet these targets carries the possibility of fines and penalties from Anatel.



After the privatization of the Brazilian telecommunications system,
authorizations were granted to new competitors wishing to offer switched fixed telephone services in the private regime, including local, intra-regional long distance, inter-regional long distance and international long distance services. Providers
granted authorizations are not subject to the same obligations concerning network expansion (universal service obligations) and continuity of service as those applicable to concessionaires providing switched fixed telephone services in the public
regime, although individual authorizations may contain certain related obligations. There are no limitations on the number of authorizations that may be granted. In July 2002, AT&T do Brasil Ltda., now Telmex do Brasil, obtained authorizations
to provide local switched fixed telephony services and domestic and international multimedia communications services, which allow it to provide facilities-based voice services. The switched fixed telephony license for local service includes the
seven largest business centers in the country.



Embratels
concession establishes a mechanism of annual rate adjustment, based on rate baskets and an adjustment for inflation. Anatel defines rate baskets for local, intra-regional long distance, inter-regional long distance and international long distance
services. While the weighted percentage increase for the entire basket is capped by Anatel, tariffs for individual services within the basket may be increased at Embratels discretion. Because Telmex do Brasil operates under an authorization
granted by Anatel and not a concession, the rates it charges its customers are not regulated by Anatel. However, Telmex do Brasil is required to publish its rates for fixed-line telephone service in Brazilian newspapers.



Competition



The strongest operators in Brazils telecommunications market are the
companies that were broken off from Telebrás, the former government-owned telephone company, upon its privatization, Telefónica (formerly Telesp), Brasil Telecom (formerly Tele Centro Sul) and Telemar (formerly Tele Norte Leste).
Following the privatization of Telebrás, three mirror companies were created by the auction of mirror licenses to provide local services over public switched networks in the same geographic areas served by the incumbent carriers.
In 2003, Embratel acquired Vésper and Vésper São Paulo, two of the three mirror companies. Global Village Telecom holds the third mirror license for local service. Intelig holds a mirror license for the provision of
intra-regional, inter-regional and international long distance service, in competition with Embratel.



Since 2002, the Brazilian federal government has been authorized to grant an unlimited number of authorizations for the provision of any type of
telecommunications service. Embratel was granted a nationwide license in August 2002 to provide local telephone service after it met certain universal service requirements.



Embratels principal competitors vary by region and type of service. In northern and eastern Brazil, Embratel competes
with Telemar and CTBC Telecom for local services and Telemar and Intelig for long distance services. In southern and western Brazil, Embratel competes with Telefónica for local

services and Telefónica and Intelig for long distance services. In São Paulo, Embratel competes with Brasil
Telecom and Global Village Telecom for local services and Brasil Telecom and Intelig for long distance services.



Investment in Net Serviços de Comunicação S.A.



We own a non-controlling interest in Net Serviços de Comunicação S.A., or Net, the largest cable
television operator in Brazil. As of December 31, 2004, Net had approximately 1.4 million connected cable television subscribers and 184 thousand subscribers to its high-speed cable modem Internet access service. Net had total revenues of U.S.$518
million (P.5,835 million) and net income of U.S.$17 million (P.192 million) during 2004.



We acquired our interest in Net in 2005 pursuant to agreements with Globo Comunicações e Participações S.A., Distel Holding S.A. and Roma Participações Ltda. (together,
Globo). After a series of transactions, we own (a) 49% of the voting interests and all of the non-voting interests in GB Empreendimentos e Participações S.A., or GB, a special-purpose company that owns 51% of the voting shares of Net
and (b) 37.4% of the voting and 7.7% of the non-voting shares of Net. Globo owns the remaining 51% of the voting interests in GB.



The total cost of these transactions was U.S.$313 million (P.3,526 million). Our total direct and indirect equity interest in Net is 37.1% (calculated by
multiplying the shares of Net held by GB by our percentage equity interest in GB, and adding the shares we own directly in Net).



Under current Brazilian law governing cable operators, because we are not controlled by Brazilian persons we are not permitted to control Net. Globo owns
a majority of the voting interests in GB, which owns a majority of the voting shares of Net. We have agreed that if Brazilian law changes to allow us to own a controlling interest in Net, we have the right to purchase an additional interest in GB to
give us control of 51% of the voting shares of Net, and Globo has the right to cause us to purchase such interest.



Possible Transactions with Embratel



We are formally evaluating whether we should sell Telmex do Brasil and our 37.1% equity stake in Net to Embratel. We believe there might be advantages to
this, because of the complementarity and possible synergies among these businesses. We would expect to receive new ordinary shares of Embratel as consideration for the acquisition of Telmex do Brasil and our interest in Net. These transactions would
present a number of important issues, including the price in shares Embratel would pay and the procedures we and Embratel would follow to negotiate and approve the transaction while protecting the interests of Embratels other shareholders. As
a result, there can be no assurance as to whether any such transaction will occur or, if it does occur, on what terms or on what timetable.



Chile



In February 2004, we acquired substantially all of the assets of AT&T Latin America including those of AT&T Chile Holding S.A., which was renamed Telmex Chile Holding S.A., or Telmex Chile.



In April 2004, we acquired an approximately 40% interest in Chilesat Corp.
S.A., or Chilesat, for U.S.$47 million from Redes Ópticas, S.A. and Redes Ópticas (Cayman) Corp., entities owned by Southern Cross Latin American Private Equity Fund L.P. and GE Capital Equity Investments, Ltd. Pursuant to a cash
tender offer required by Chilean law, in June 2004 we purchased an additional 59.3%, increasing our ownership of Chilesat to 99.3%. We changed the name of Chilesat to Telmex Corp. S.A., or Telmex Corp.

##### Table of Contents

We provide voice, Internet and data services to more than 500 thousand corporate and residential
customers in Chile. In 2004, we integrated the operations of Telmex Corp. and Telmex Chile. To corporate customers, we provide local service, private long distance networks, virtual private networks, Internet services and other value-added services,
as well as video and audio satellite links for broadcasting corporations. For residential customers, in addition to local service, we are focusing on long distance and Internet services, including value-added services with the goal of increasing our
overall profitability. Our multi-service platform, IP/MPLS, allows us to provide integrated voice, data and video services, along with Next Generation VoIP services.



Our fiber optic network comprises more than 4,200 kilometers of physical cable, which cover the continental territory of
Chile from Arica to Santiago, Santiago to Valparaiso and Santiago to Valdivia. In 2002, to cover the segment between Valparaiso and Puerto Montt, a capacity exchange was carried out with Telefónica del Sur S.A. In the southern regions of the
country, we use a satellite platform. We also own and operate metropolitan fiber networks covering Santiago and Chiles other major cities.



Of our revenues from our Chilean operations in 2004, almost two-thirds were attributable to voice services, approximately one-third was attributable to
data and Internet services and the remainder was attributable to other services. Telmex Corp. and Telmex Chile together have a market share of 33.3% in the national long distance market, 10.8% in the international long distance market and 1.7% in
the local service market.



The General Telecommunications Law
(No. 18,168) of 1982, as amended, established the legal framework for the provision of telecommunications services in Chile. The law established the rules for granting concessions and permits to provide telecommunications services and for the
regulation of rates and interconnection. The main regulatory agency of the Chilean telecommunication sector is the Ministry of Transportation and Telecommunications, which acts primarily through the Undersecretary of Telecommunications, or SUBTEL.



We hold licenses to provide local service, domestic and
international long distance service, data services and value-added services.



We face strong competition in all of our business segments and we compete with Telefónica CTC Chile, the ultimate parent of which is Telefónica S.A., Entel S.A. and five other carriers. This competition
has mainly been vigorous in international and national long distance public markets since implementation of the multicarrier system, which requires local telephone companies to provide facilities that allow long distance carriers to access the local
telephone network on an equal access basis. We, Entel and other similar companies compete on an equal access basis in the national long distance and international long distance Chilean market.



Although competition remains strong, the Chilean long distance industry has
demonstrated signs of increased stability due to the settlement of legal and operational disputes among competitors, mergers between certain facilities and non-facilities-based carriers and the existence of the Long Distance Carriers Association, an
institution dedicated to solving the various problems of the industry.



Argentina



Techtel-LMDS Comunicaciones
Interactivas, S.A., or Techtel, provides data, Internet and voice services in Argentina. Telmex Argentina S.A. provides data, Internet and voice services to corporate customers in Argentinas largest cities. Our principal subsidiaries in
Argentina are Telmex Argentina, Techtel and Metrored Telecommunicationes S.R.L., or Metrored. Metrored operates fiber optic rings in metropolitan areas that provide last mile access to reach our customers.

Through its digital fiber optic network, Telmex Argentina offers local, long distance, data and Internet
access to corporate and residential customers. Through its two data centers it also offers data administration and hosting, among other services.



In April 2004, we acquired an 80% indirect interest in Techtel in two separate purchases. We acquired a 20% interest from an affiliate of Techint
Compañía Técnica Internacional S.A.C.I., or Techint, one of Argentinas largest industrial groups, for U.S.$25 million. We subsequently acquired a 60% interest from América Móvil, on the same pricing terms,
for U.S.$75 million. In June 2004 we capitalized Techtel with U.S.$26.2 million to buy Metrored and to repay debt of Techtel. This capitalization increased our ownership of Techtel by 3.4%.



After the capitalization, the Techint affiliate continued to hold the
remaining 16.6% indirect interest in Techtel. Pursuant to an agreement with the Techint affiliate, on June 23, 2005, we exercised our right to acquire an additional interest in Techtel of approximately 10% for which we paid U.S.$15 million,
increasing our ownership to 93.4%. Pursuant to a further agreement with the Techint affiliate, we have a right to acquire, and the Techint affiliate can cause us to acquire, in 2007, its remaining 6.6% indirect interest in Techtel for U.S.$10
million. In addition, we have agreed to pay Techints affiliate, Tecnologia en Servicios UrbanosTESUR S.A., a U.S.$6 million consulting fee for management services to be rendered through December 2006.



Techtel operates a local multipoint distribution service, or LMDS, and fiber
optic network in Argentina, providing voice, data and video transfer services and other related telecommunications services. LMDS is a wireless broadband technology that uses radio signals to transmit voice, video and data. Techtel began providing
long distance fixed-line voice services and call center support in December 2000 and launched local fixed-line voice services in August 2001. In June 2004, Techtel acquired a controlling interest in Metrored, which has one of the largest fiber optic
networks in Buenos Aires.



We have a fiber optic network of
over 4,000 km that covers thirteen cities in Argentina and reaches approximately 68% of its population. Our voice network covers approximately 46 cities.



Of our revenues from our Argentine operations in 2004, over one-half was attributable to voice services, approximately 40% was attributable to data
services and the remainder was attributable to other services.



We hold licenses to provide local, domestic and international long distance telephone service, public telephony, data services, value-added services and video conferencing.



Peru



Through Telmex Perú S.A., we provide domestic and international long distance services, public telephones, and data, Internet and hosting services
to corporate and residential customers in Peru through a fiber optic network.



Revenues of our Peruvian operations for the full year 2004 were P.465.7 million, of which nearly two-thirds were attributable to voice services, approximately one-third was attributable to data services and the
remainder was attributable to other services.



The main
regulatory agency of the Peruvian telecommunications sector is the Ministry of Transportation and Communication. Telmex Perú holds concessions to provide local, domestic and international long distance service.

Our main competitor in fixed local telephony services, public telephone services, data services and
Internet services is Telefónica del Perú, S.A., and in long distance telephony services our main competitors are Americatel Perú S.A., a Telecom Italia Group affiliate, and Telefónica del Perú.



Colombia



Through Telmex Colombia S.A., we provide data and Internet services to corporate clients in Colombia through a metropolitan
and inter-city fiber optic network.



Of our revenues from our
Colombian operations for 2004, over 90% was attributable to data and Internet services and the remainder was attributable to other services.



We hold licenses to provide local, domestic and international long distance service, mobile telephone service, data services, value-added services and
video conferencing.



United States



In April 2003, the U.S. Federal Communications Commission, or FCC, granted
our U.S. subsidiary, Telmex USA, a facilities-based authorization that permits Telmex USA to install and operate telecommunications facilities in the United States. Telmex USA also holds an FCC authorization to resell long distance services in the
United States. As a result of our acquisition of the assets of AT&T Latin America and of Embratel, we hold two additional facilities-based and resale-based authorizations. We are in the process of evaluating potential future operations in the
United States.

CAPITAL EXPENDITURES



The
following table sets forth, in constant pesos as of December 31, 2004, our capital expenditures, before retirements, for each year in the three-year period ended December 31, 2004:



|                                            |  |                                                         |  |           |  |

Our investment in
capital expenditures increased by 89.9% in 2004 due to an increase in our investments in Mexico and the inclusion of the investments made by our non-Mexican subsidiaries following our consolidation of the respective businesses.



We have budgeted capital expenditures in an amount equivalent to
approximately U.S.$2.14 billion for the year 2005, including U.S.$1.55 billion in Mexico, U.S.$473 million for Embratel principally for investments related to the C1 and C2 satellites and U.S.$117 million for our other operations in Brazil,
Argentina, Chile, Peru and Colombia. See Item 5. Operating and Financial Review and ProspectsLiquidity and Capital Resources.



OTHER MATTERS



Investments



General



We occasionally make investments and joint ventures in
telecommunications-related businesses within and outside Mexico. To date in 2005, we have made investments totaling U.S.$924 million, including U.S.$611 million in Embratel through subscription to its capital increase and U.S.$313 million to acquire
a 37.1% equity interest in Net. We also invest in publicly traded equity securities of companies in technology and communications businesses. At December 31, 2004, we had U.S.$658 million of marketable securities on our balance sheet. Our marketable
securities are carried at market value, and gains and losses are recognized in our statement of income.



MCI, Inc.



Through a wholly owned subsidiary, we invested in several series of bonds of MCIs predecessor, WorldCom, Inc. As of December 31, 2003, we held
approximately U.S.$1,759 million in face amount of the bonds, with a market value of approximately U.S.$589 million at such date.



In April 2004, MCI emerged from bankruptcy pursuant to a reorganization plan approved by the U.S. bankruptcy court in October 2003. Under the
reorganization plan, in exchange for our bonds, we received approximately 25.6 million shares of common stock of MCI, which represented approximately 8.1% of MCIs outstanding common stock. Other parties that may be deemed to be under common
control with us held an additional interest of approximately 5.7% of MCIs outstanding common stock.

##### Table of Contents

On April 9, 2005, we and certain parties related to us entered into an agreement with Verizon
Communications Inc. and certain of its subsidiaries, together Verizon, to sell to Verizon our entire interest in common shares of MCI for a cash purchase price of U.S.$25.72 per share. We received approximately U.S.$660 million for our 25.6 million
MCI shares on May 17, 2005. We expect to recognize a gain of close to U.S.$58 million before taxes, which is in addition to gains recognized in prior periods. If, on the third trading date prior to the first anniversary of this agreement, Verizon
Communicationss average stock price for the preceding 20 trading days exceeds U.S.$35.52 per share (subject to adjustment in certain circumstances), we will be entitled to receive an additional cash payment per share equal to approximately
72.4% of the excess. The additional cash payment to which we will be entitled will be capped at approximately U.S.$19.54 per share if Verizon Communicationss planned merger with MCI has been consummated by the third trading date prior to the
first anniversary of our agreement with Verizon.



Property, Plants and
Equipment



We have transmission facilities, exchanges,
outside plant and commercial and administrative offices throughout Mexico. We own most of the locations of our exchanges and offices and lease other locations. We hold a small number of operating properties under financial leases, but the aggregate
amount of such financing is not material to our operations as a whole. We carry casualty insurance against loss or damage to buildings, equipment contained in buildings and outside plant, including our fiber optic network. Outside Mexico, we hold
additional facilities and offices in Brazil, Chile, Argentina, Peru and Colombia.



We have purchased equipment from a variety of suppliers, and there are sufficient alternative sources of equipment so that interruption of any source would be unlikely to cause a significant disturbance to our
operations or our investment plan.



The Telmex Foundation



Since 1996, we have sponsored a philanthropic foundation called
Fundación Telmex, A.C., or the Telmex Foundation, which is active in the charitable areas of education, health, justice and culture. We do not consolidate the Telmex Foundation in our financial statements. We contributed P.578 million in
2001. We did not contribute to the Telmex Foundation in 2002, 2003 or 2004, and do not expect to contribute to the Telmex Foundation in 2005. The assets of the Telmex Foundation are devoted only to its charitable activities, and our contributions
are deductible for purposes of the Mexican Income Tax Law.



During 2004, the Telmex Foundation provided over 10,000 scholarships, donated over 3,300 personal computers and over 2,800 printers, and provided approximately 2,750 eyeglasses for children. The Telmex Foundation also works in conjunction
with the Mexican governments health agencies in providing specialized health care to people in remote areas through a surgery program that funded treatment for over 28,700 patients in 2004. The Telmex Foundation also works to increase
participation in organ donor registries. In cooperation with non-governmental organizations, the Telmex Foundation provided assistance to nearly 7,000 persons charged with minor crimes whose lack of financial resources prevented them from otherwise
posting bail during 2004.

Item 5. Operating and Financial Review and Prospects



The following discussion should be read in conjunction with the consolidated financial statements and notes thereto included in this Annual Report.



Our consolidated financial statements have been prepared in accordance with Mexican GAAP, which differ in certain respects
from U.S. GAAP. Note 19 to our audited consolidated financial statements provides a description of the principal differences between Mexican GAAP and U.S. GAAP, as they relate to us; a reconciliation to U.S. GAAP of operating income, net income and
total stockholders equity; and a condensed statement of cash flows under U.S. GAAP.



Mexican GAAP requires that the financial statements recognize certain effects of inflation. In particular:



| |  |  | nonmonetary assets (excluding plant, property and equipment of non-Mexican origin) and stockholders equity are restated for inflation based on the Mexican National Consumer
Price Index;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | plant, property and equipment of non-Mexican origin are restated based on the rate of inflation in the country of origin and converted into Mexican pesos using the prevailing
exchange rate at the balance sheet date;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | gains and losses in purchasing power from holding monetary assets and liabilities are recognized in income; and
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | all financial statements are restated in constant pesos as of December 31, 2004.
| | - |  | --------------------------------------------------------------------------------



We have not reversed the effect of inflation accounting under Mexican GAAP in the reconciliation to U.S. GAAP of our net income and
stockholders equity, except with respect to the methodology for restatement of plant, property and equipment of non-Mexican origin. See Note 19 to our consolidated financial statements.



Overview



Our financial statements are presented in constant pesos, so all financial information is restated in pesos with purchasing
power as of December 31, 2004. We refer to constant-peso figures as being real, as opposed to nominal. If nominal revenues or income do not increase by at least the rate of inflation, they decrease in real terms.



In 2004, as a part of our strategy for growth, we acquired operations in
Brazil and four other countries in Latin America where we now offer voice, data and Internet services, among other services. Total revenues grew 12.9% in 2004, primarily because of these acquisitions. Revenues from our new non-Mexican operations
represented 11.3% of total revenues in 2004. We expect the contribution of our non-Mexican operations to total revenues to increase in 2005 when we consolidate the results of our non-Mexican operations for the full year.



In Mexico, our revenues grew slightly in 2004 due to strong growth in
Internet services and corporate networks, despite a decrease in revenues for local and domestic and international long distance services. We did not raise our nominal rates in 2003 or 2004, and we gave discounts for some domestic long distance and
connectivity services, so in real terms our prices have continued to fall. The number of lines in service has continued to grow, but average revenue per line has declined, partly because we have added new customers who have less disposable income
and make less use of their lines.



39

##### Table of Contents

Competition and changing technologies have had extensive effects on our financial performance, and it is
difficult to predict their future impact. We expect continued pressure on prices for long distance services. In local service, the rapid growth in mobile telecommunications has made them the principal competitor for local networks. In addition,
local service faces competition from other means of communication such as private circuits and the Internet, including VoIP, a technology that transmits ordinary telephone calls over the Internet. The growth of other service providers in long
distance and mobile has made interconnection fees a growing component of both our revenues and our costs. The number of our broadband subscribers grew by 212.5% in 2004 and we expect that it will continue to grow and to affect usage of other
services. Revenues from voice services (including local, long distance and interconnection) represented 80.5% of our consolidated 2004 revenues while revenues from corporate networks and Internet services represented 15.2% but were growing at a much
faster pace.



Faced with uncertain potential for growth in
revenues and operating income in the Mexican market, we have worked to control costs while integrating the non-Mexican businesses we acquired in 2004. The consolidation of these businesses increased our revenues and operating income in 2004, but
decreased our overall operating margin. It is likely that the results of our non-Mexican subsidiaries will continue to adversely impact our overall operating margin in the future.



Our future results may be affected significantly by the general economic and financial conditions in the countries where we
operate, including levels of economic growth, devaluation of the local currency, inflation or high interest rates. Exchange rate variations on our U.S. dollar-denominated indebtedness, and the effect of inflation on our net monetary liabilities,
contribute to the volatility of our comprehensive financing cost.



Effects of Recent Acquisitions



In 2004, we
acquired Techtel, Chilesat, Metrored, a majority of the voting stock of Embratel and substantially all of the assets of AT&T Latin America. The consolidation of these companies affects the comparability of our 2004 results to our 2003 results
and will continue to affect comparability in 2005, particularly since the largest of our 2004 acquisitions were not consolidated until the third quarter of 2004.



Our consolidated financial statements reflect the consolidation of these companies as follows:



| |  |  | Telmex Argentina, Telmex do Brasil, Telmex Chile, Telmex Colombia and Telmex Peru (holding the assets of AT&T Latin America in each respective country) (from March 1, 2004),
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Techtel (from May 1, 2004),
| | - |  | ---------------------------



| |  |  | Metrored (from July 1, 2004),
| | - |  | -----------------------------



| |  |  | Chilesat, now Telmex Corp. (from July 1, 2004) and
| | - |  | --------------------------------------------------



| |  |  | Embratel (from August 1, 2004).

Revenues



Total revenues in 2004 were P.138,802 million, an increase of 12.9% over 2003, due primarily to the consolidation of our non-Mexican operations. Of our
total revenues in 2004, 80.5% was attributable to voice services, which includes local, long distance and interconnection services, and 15.2% was attributable to corporate networks and Internet services.



In 2005, we will consolidate for the full year the non-Mexican operations we
acquired during 2004. As a result, we expect that the portion of revenues attributable to our Mexican operations (88.7% in 2004) to decrease in 2005. We also expect that voice services will represent a smaller portion of total revenues in 2005 as a
result of our consolidation of the revenues from corporate networks and Internet services of our non-Mexican operations. In 2004, voice services represented more than 70% of Embratels revenues.



Local Service Revenues



Operating revenues from local service include installation charges for new
lines, monthly line rental charges, monthly fees for digital service and monthly measured service charges based on the number of calls. These revenues depend on the number of lines in service, the number of new lines installed and the volume of
calls. In Mexico, measured service charges are due from residential customers only for the number of local calls exceeding a specified monthly minimum. Accordingly, revenues from local service for residential customers do not depend solely on usage
volume. Operating revenues from local service also include miscellaneous charges, such as fees paid by long distance carriers related to certain costs of modifying our network to accommodate interconnection and fees for reconnecting customers.



Revenues from local service increased by 0.5% in 2004 and
decreased by 2.5% in 2003. The increase in 2004 was primarily due to the consolidation in August 2004 of the local service revenues of Embratel. Without the local service revenues of Embratel, revenues from local service would have decreased by
1.1%, as total local traffic in Mexico increased by only 0.6%. Revenues from our Mexican operations declined in 2004 and 2003 because of lower real rates, which resulted from inflation, as our nominal rates remained unchanged for the fourth year.
Traffic increased slightly, reflecting the effects of economic growth and increased competition. These effects were partially offset by the higher penetration of digital services, growth of voicemail and an increase in the number of lines in service
to 17,172 thousand at December 31, 2004 from 15,683 thousand at December 31, 2003 and 14,446 thousand at December 31, 2002. The proportion of lines with at least one digital service (such as call waiting, caller ID, voicemail, three-way calling and
call forwarding) rose to 38.2% in 2004, compared with 35.0% in 2003 and 30.2% in 2002. Income per line decreased to P.302.3 in 2004 from P.334.5 in 2003.



Domestic Long Distance Revenues



Operating revenues from domestic long distance service depend on rates and traffic volume. Domestic long distance revenues increased by 32.3% in 2004 and
decreased by 1.9% in 2003. The increase in 2004 was primarily due to the consolidation of long distance revenues amounting to P.7,693 million from Embratel and other subsidiaries outside Mexico. With respect to our Mexican operations, although
billed minutes increased by 8.6% to 16,700 million in 2004 from 15,376 million in 2003, domestic long distance revenues declined by 8.5% due to lower real rates. In 2003, revenues from domestic long distance services decreased due to lower real
rates, partly offset by increased traffic. The number of billed minutes increased by 7.2% to 15,376 million in 2003 from 14,347 in 2002.

##### Table of Contents

International Long Distance Revenues



Operating revenues from international long distance service consist of (a)
amounts earned from our customers and (b) amounts earned from foreign telecommunications carriers for terminating international calls. The amount of operating revenues from international long distance service depends on the volume of traffic, the
rates charged to our customers, the rates charged by each party under agreements with foreign carriers, principally in the United States, and the effects of competition. The contribution of net settlements from foreign carriers represented 1.9% of
our consolidated revenues in 2004 and 24.7% of our international long distance revenues in 2004. Settlement payments under service agreements with foreign carriers are generally denominated in U.S. dollars.



International long distance revenues increased by 17.2% in 2004 and decreased
by 8.1% in 2003. The increase in 2004 was due to the consolidation of international long distance revenues amounting to P.1,600 million from Embratel and other subsidiaries outside Mexico. Without this revenue, there would have been a decrease in
revenue of 0.4% due to lower real rates and customer discounts, partially offset by a large increase in traffic. Outgoing billed minutes grew by 7.9%, while incoming billed minutes grew by 54.8% due to lower international settlement rates and lower
illegal bypass.



The decrease in 2003 was due to
(i) lower real rates billed in Mexico and (ii) lower incoming traffic, which we attribute, in part, to illegal bypass, both of which were partly offset by higher outgoing traffic, principally to the United States.



We estimate that illegal bypass decreased our revenues by approximately
P.1,769 million in 2004 and approximately P.2,661 million in 2003. Our estimated lost revenues consisted of settlement payments that we otherwise would have received but for illegal bypass.



In August 2004, Mexico eliminated its uniform settlement rate system, its
proportional return system and its requirement that the Mexican carrier with the greatest share of outgoing traffic to a particular country negotiate the settlement rate on behalf of all Mexican carriers for that country. Because each Mexican
carrier is now free to negotiate settlement rates with each foreign carrier, this form of bypass has disappeared.



Revenues from Interconnection



Revenues from interconnection represent fees for connection to our network of fixed-to-mobile, mobile-to-fixed and long distance calls. In Mexico, under
the calling party pays system, our fixed-line customers pay us an interconnection charge when they call mobile customers, and we pay approximately three-quarters of that amount to the mobile carrier that completes the call. We recognize
the amount the customer pays us under interconnection revenue, and we recognize the amount we pay to the mobile carrier under interconnection cost. For our Mexican operations, revenue from fixed-to-mobile calls represented 89.9% of interconnection
revenues in 2004 and 92.3% in 2003, and revenues from competing local and long distance carriers represented 7.8% of interconnection revenues in 2004. The balance of interconnection revenues represents payments from cellular carriers for
mobile-to-fixed calls.



Revenues from interconnection increased
by 3.9% in 2004 and by 8.6% in 2003. The increase in 2004 was due in part to the inclusion of revenue from non-Mexican operations, in particular Embratel, without which the growth would have been 1.4%. For our Mexican operations, revenues from
calling party pays decreased in 2004 by 1.1%, but this decrease was more than offset by growth in revenue from interconnection of local, long distance and cellular operators. The increase in 2003 was due to growth in calling party
pays minutes. In addition, in 2003, the increase resulted from growth in minutes from long distance carriers.

Revenues from Corporate Networks



Revenues from corporate networks include revenues primarily from the
installation and leasing of dedicated private lines and revenues from virtual private network services.Revenues from corporate networks increased by 48.0% in 2004 and decreased by 4.4% in 2003. A large part of the increase in 2004 was
due to the consolidation of our non-Mexican operations, in particular Embratel. Without the non-Mexican operations, revenues would have increased by 7.3% due to the increase in line equivalents and the expansion of our administrative networks
business, partially offset by customer discounts and lower real rates. The decrease in 2003 was due to customer discounts and lower real rates as a result of inflation.



Revenues from Internet Services



Revenues from Internet services include set-up and service fees for dial-up and broadband Internet access. Revenues from
Internet services increased by 45.3% in 2004 and by 27.1% in 2003. The increase in 2004 was due in part to the inclusion of revenue from our non-Mexican operations, in particular Embratel, without which the growth would have been 25.0%. The increase
in Mexico was due to an increase in the number of broadband (ADSL) customers, which grew by 212.5%, from 179.3 thousand at the end of 2003 to 560.3 thousand at the end of 2004. The increase in 2003 was due to an increase in both dial-up and
broadband customers.



Other Revenues



The largest components of other revenues are sales of yellow pages
advertising, telecommunications equipment and accessories and billing and collection services offered to third parties. Other revenues increased by 8.9% in 2004 and decreased by 0.3% in 2003. The increase in 2004 was due to growth in Mexican other
revenues and the effect of the consolidation of Embratel. In Mexico, other revenues increased by 3.3% in 2004 due to growth in revenue from the sale of telecommunications materials and billing and collection services offered to third parties. The
decrease in 2003 was principally due to lower revenues from yellow pages advertising, particularly in the Mexico City, Guadalajara and Monterrey directories, and a delay in the recognition of revenues from two directories, the publication of which
was postponed from December 2003 until February 2004. The effects were partially offset by higher revenues from the sale of telecommunications equipment and accessories and billing and collection services to third parties.



Operating Costs and Expenses



Cost of Sales and Services



Cost of sales and services increased by 7.0% in 2004 and by 0.7% in 2003.
The increase in 2004 was due to the consolidation of our non-Mexican operations. In 2004, cost of sales and services for our Mexican operations increased by only 1.1%, due to the expansion of our telephone plant and to expenses related to
maintenance of our data network, partially offset by lower expenses for pensions and lower costs for computers for resale to customers. The increase in 2003 was mainly due to higher expenses for pensions and seniority premiums, the increase of
electricity rates and higher costs for telephone sets and computers, partially offset by decreased expenses for maintenance of outside plant and systems, and lower production costs for telephone directories.

##### Table of Contents

Commercial, Administrative and General Expenses



Commercial, administrative and general expenses increased by 21.9% in 2004
and by 0.2% in 2003. In 2004, the increase was due to the inclusion of expenses from our non-Mexican operations. In 2004, for our Mexican operations, these expenses decreased by 0.7%, due to lower expenses for pensions and lower costs for prepaid
phone cards. In 2003, we maintained strict cost control policies, including the continued reduction of marketing expenditures, and we reduced the cost of prepaid cards. This cost control policy helped reduce the impact of higher expenses in pensions
and seniority premiums and higher payments to third-party service providers. In addition, we made no contributions to the Telmex Foundation in 2003. As a result, we maintained commercial, administrative and general expenses at almost the same level
as in 2002.



Interconnection and Transport



Costs from interconnection include payments we make
in Mexico, principally to cellular carriers under calling party pays, and costs from transport include fees paid by our non-Mexican subsidiaries for the use of facilities to complete their calls in areas where they do not have a network.
Total interconnection and transport costs increased by 52.6% in 2004 due primarily to the inclusion of our non-Mexican operations. Interconnection costs for our Mexican operations increased by 0.3% in 2004 and 4.1% in 2003, due in both years to the
growth in traffic from our customers terminating calls on the networks of other operators, especially cellular operators.



Depreciation and Amortization



Depreciation and amortization increased by 5.4% in 2004 and by 1.7% in 2003. Under Mexican GAAP, we restate imported fixed assets based on the exchange
rate between the peso and the currency of the country of origin and the inflation of the country of origin. As a result, changes in exchange rates and inflation rates affect the amount of depreciation. In 2004, the increase was due to the inclusion
of our non-Mexican operations, principally Embratel. For our Mexican operations, depreciation and amortization decreased by 7.3% due to lower depreciable assets, reflecting declining equipment prices and the fact that the rate of Mexican inflation
exceeded the rate of devaluation of the peso in 2004. Depreciation and amortization increased in 2003 because the rate of devaluation exceeded the rate of Mexican inflation and we reduced the useful lives of certain assets to respond to
technological changes. These effects were offset by a decrease in the amount of our depreciable assets, as the rate of our investment has slowed and an increased proportion of our assets has fully depreciated.



Operating Income



In 2004, operating income increased by 4.5%, reflecting a 12.9% increase in revenues and a 17.3% increase in costs. Our
operating margin decreased to 31.5% in 2004 from 34.0% in 2003 due to the consolidation of our non-Mexican operations, which had lower operating margins than our Mexican operations. In 2004, operating income from our Mexican operations
increased by 3.7%, reflecting a 0.1% increase in revenues and a 1.7% decrease in operating costs and expenses. Operating margin from our Mexican operations increased to 35.2% in 2004 from 34.0% in 2003, due to decreased costs and expenses, including
lower depreciation. The operating margin of our Mexican operations reflects an increase in our margin for other services (from 36.0% in 2003 to 44.1% in 2004).



In 2003, operating income decreased by 3.5%, reflecting a 0.3% decrease in revenues and a 1.4% increase in operating costs
and expenses. As a result, the operating margin decreased by 1.0%, to 34.0% in 2003 from 35.0% in 2002. The decrease in operating margin reflects a small decrease in margin for local service (from 30.9% to 30.6%) and a larger decrease in the margin
for long distance service (from 31.9% to 28.1%), primarily because of lower real rates for both local and long distance services.

##### Table of Contents

In Mexico, we operate in two primary segments, local and long distance, and several smaller segments that
we group together for reporting purposes. These other segments include connectivity, Internet, public and rural telephones, directories and other services. We group all of our Latin American operations other than those in Mexico into an additional
segment. See Note 18 to our consolidated financial statements. Local service in Mexico represents more than half of our operating income and accounts for a majority of our operating cash flow and of our capital expenditure requirements. In 2004,
operating margin was 30.4% in our local segment, 27.0% in our long-distance segment and 44.1% in our other segments in Mexico and 2.2% in Latin America.



Comprehensive Financing Cost



Under Mexican GAAP, comprehensive financing cost reflects interest income, interest expense, foreign exchange gain or loss and the gain or loss
attributable to the effects of inflation on monetary liabilities and assets. A substantial proportion of our indebtedness (90.3% at December 31, 2004) is denominated in foreign currencies, so when there is depreciation of the peso it results in
foreign exchange loss and higher interest expense. Most of our financial assets are denominated in foreign currencies.



In 2004, comprehensive financing cost was P.521 million (88.3% lower than in 2003), as compared with P.4,472 million in 2003 (36.5% lower than in 2002).
The changes in each component were as follows:



| |  |  | Interest income decreased by 5.2% in 2004 and increased by 128.9% in 2003. Interest income included gains on marketable securities of approximately P.202 million in 2004 and P.2,273
million in 2003. Excluding these gains in both years, interest income would have increased 214.7% in 2004, due principally to inclusion of P.673 million of interest income of Embratel and P.231 million in dividends on its shares of MCI. The increase
in 2003 was mainly due to the recognition of P.2,273 million of unrealized gain on marketable securities (P.1,937 million of it attributable to MCI securities). Excluding this amount, interest income decreased by 36.6% in 2003, reflecting lower
average treasury balances after the investment in MCI and lower interest rates in Mexico and abroad.

| |  |  | Interest expense increased by 5.3% in 2004 and decreased by 8.3% in 2003. The increase in 2004 was primarily due to the inclusion of P.1,169 million in interest expense of Embratel
and the P.327 million premium paid for repurchases of our convertible senior debentures. In 2003, we recognized P.1,012 million related to the cancellation of our peso-denominated interest-rate swaps. Excluding the interest expense related to the
cancellation of these swaps, interest expense would have increased by 26.4% in 2004. In 2002, we recognized P.1,182 million of unrealized loss on marketable securities (P.672 million of it attributable to MCI securities). Excluding this amount,
interest expense increased by 11.5% in 2003, reflecting a charge of P.481 million on swap contracts and an additional charge of P.1,012 million related to the cancellation of peso-denominated interest-rate swaps by other swaps at more attractive
rates.

| |  |  | In 2004, we recorded a net exchange gain of P.26 million. In 2004, the peso depreciated against the U.S. dollar at year-end by approximately 0.3%, but our loss in Mexico was more
than offset by a gain at our non-Mexican subsidiaries, particularly Embratel. In 2003, the depreciation of the peso against the U.S. dollar by 9.0% resulted in a net exchange loss of P.3,296 million, compared to a net exchange loss of P.4,861
million in 2002.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Because average monetary liabilities exceeded average monetary assets, we recognized a net gain from monetary position. The net gain in monetary position increased by 64.0% in 2004
due to a higher net monetary position and a higher inflation rate compared to 2003. The net gain in monetary position decreased by 43.1% in 2003 due to a lower net monetary position and a lower inflation rate compared to 2002.

Income Tax and Employee Profit Sharing



The statutory rate of the Mexican corporate income tax was 33.0% in 2004,
34.0% in 2003 and 35.0% in 2002. The Mexican Income Tax Law was amended in 2004 to decrease the corporate income tax rate to 30% in 2005, 29% in 2006 and 28% thereafter. Our effective rate of corporate income tax as a percentage of pre-tax profit
was 28.7% in 2004, 28.9% in 2003 and 31.2% in 2002. The effective tax rate was slightly lower in 2004 than in 2003 due to the effect of the reduction in the Mexican corporate income tax rate, partly offset by a decrease in comprehensive financing
cost and the contribution of taxes imposed on foreign subsidiaries. The effective tax rate was lower in 2003 than in 2002, due to unrealized gains in marketable securities recognized in 2003.



Like other Mexican companies, we are required by law to pay to our employees,
in addition to their agreed compensation and benefits, profit sharing in an aggregate amount equal to 10% of our taxable income (calculated without reference to inflation adjustments). The employee profit sharing amount increased by 3.8% in 2004 and
decreased by 17.2% in 2003. The increase in 2004 was due to higher income before income tax. The decrease in 2003 was due principally to the increase in tax-deductible contributions we made to our pension plan.



Net Income



Net income increased by 17.9% in 2004 and by 10.3% in 2003. In 2004, the
increase was due to a 4.5% increase in operating income and the stability of the peso against the U.S. dollar. In 2003, the increase was principally due to a 36.5% decrease in comprehensive financing cost and a 7.4% decrease in the provision for
income tax and employee profit sharing.



Results of Operations by Segment



We discuss below our operating results by segment. All
amounts discussed below are presented in accordance with Mexican GAAP. Note 1(a) of our financial statements included in this annual report describes how we translate the financial statements of our non-Mexican subsidiaries. For the Latin America
segment, we restate the financial statements of foreign subsidiaries for inflationary effects using restatement factors of the relevant country and then convert foreign currency amounts into Mexican pesos, using, for items from our income statement,
the exchange rate between the Mexican peso and the local currency at the end of the applicable year. Accordingly, changes in local inflation rates and in exchange rates could significantly affect reported results in Mexican pesos and the
comparability of reported results with those of prior years.



MexicoLocal Service



Operating
revenues from local service in Mexico represented 64.5% of our consolidated revenues in 2004. Operating revenues decreased by 0.4% in 2004 due to lower real rates resulting from inflation and increased by 0.9% in 2003 due to increased revenues from
interconnection, partly offset by lower real rates resulting from inflation.



Operating income for local service represented 62.3% of our consolidated operating income in 2004. Operating income decreased by 1.2% in 2004 and increased by 0.1% in 2003. Our operating margin was 30.4% in 2004 and
30.6% in 2003.

MexicoLong Distance Service



Operating revenues from long distance service in Mexico represented 17.5% of
our consolidated revenues in 2004. Operating revenues decreased by 5.7% in 2004 and by 3.6% in 2003 due to lower real rates and customer discounts.



Operating income for long distance service represented 15.0% of our consolidated operating income in 2004. Operating income decreased by 9.3% in 2004 and
by 15.1% in 2003. Our operating margin was 27.0% in 2004 and 28.1% in 2003. The decrease in operating margin in 2004 reflects lower rates partly offset by a decrease in illegal bypass.



MexicoOther Services



Operating revenues from other services in Mexico represented 15.6% of our consolidated revenues in 2004. Operating revenues
increased by 11.1% in 2004 due mainly to increased revenues from corporate networks and Internet services. Operating revenues from other services decreased by 1.0% in 2003 due to lower intersegment revenues.



Operating income for other services in Mexico represented 21.9% of our
consolidated operating income in 2004. Operating income increased by 36.1% in 2004. In 2003, operating income for other services decreased by 3.4%. Our operating margin was 44.1% in 2004 and 36.0% in 2003. The increase in operating margin in 2004
reflects increased revenues from corporate networks and Internet services.



Latin America



Our Latin America segment includes all operations outside of Mexico. This segment is new in 2004 as a result of acquisitions. Operating revenues from Latin America represented 11.4% of our consolidated operating revenues in 2004, and this
percentage will increase in 2005. In the first quarter of 2005, our Latin America segment represented 23.3% of consolidated operating revenues. Revenues from this segment are principally from long distance service.



Operating income from our Latin American operations was P.341 million in
2004, which represented 0.8% of our consolidated operating income. Our operating margin was 2.2%. We hope that our efforts to reduce costs for these businesses will lead to an increase in our operating margin in our Latin America segment in the
future.



Liquidity and Capital Resources



Our principal capital requirements are for capital expenditures, dividend
payments, our share repurchase program and acquisitions. In addition, in 2003 and 2002 we used cash to acquire debt securities of MCI. We have generally met our capital requirements primarily from operating cash flows and limited borrowing.
Resources provided by operating activities were P.60,945 million in 2004, P.27,630 million in 2003 and P.38,958 million in 2002. Our resources provided by operating activities increased due to the decreased application of resources to exchange
securities, accounts payable, accrued liabilities, taxes payable and pension fund contributions.



Our capital expenditures were P.20,375 million in 2004, P.10,728 million in 2003 and P.12,227 million in 2002. The 89.9% increase in 2004 was due both to
higher investment in Mexico and to the consolidation of Embratel, and we expect that our capital expenditures will be approximately U.S.$2.0 billion for 2005. Budgeted capital expenditures for 2005 exclude any other investments we may make to
acquire other companies. For subsequent years, our capital expenditures will depend on economic and market conditions.

The amount spent on share repurchases was P.13,893 million in 2004, P.12,078 million in 2003 and P.6,797
million in 2002. The amount spent on share repurchases is determined from time to time by the executive committee taking into account factors including the price of our shares and our capital resources. The shareholders have given renewed
authorization to our officers to make share repurchases, most recently on April 28, 2005. There is no obligation to spend any of the authorized amounts. See Item 16E. Purchases of Equity Securities by the Issuer and Affiliated
Purchasers.



Dividends paid totaled P.8,144
million in 2004, P.8,018 million in 2003 and P.7,887 million in 2002. The shareholders have approved dividends of P.0.38 per share (post-split) to be paid in four installments out of 2004 income. We expect to pay an aggregate of approximately P.8.8
billion in dividends from June 2005 through March 2006 (based on the number of outstanding shares at May 23, 2005).



We had a working capital surplus (an excess of current assets over current liabilities) of P.11,604 million at December 31, 2004. Our current assets at
December 31, 2004 included the shares of MCI that we sold to Verizon in May 2005. See Item 4. Information on the CompanyOther MattersInvestmentsMCI, Inc.



In the table below we set forth certain contractual obligations as of December 31, 2004, consisting of debt (including
financial leases) and purchase obligations, and the period in which the contractual obligations come due. We do not expect to contribute to our pension funds in 2005 and the extent of future contributions will depend on the performance of our plan
assets and actuarial calculations in future years. The table below does not include pension liabilities, deferred taxes or current accounts payable.

At December 31, 2004,
we had total indebtedness of P.90,041 million compared to total indebtedness of P.72,243 million at December 31, 2003. The increase is attributable primarily to the consolidation of Embratel, which had P.13,727 million of indebtedness at December
31, 2004, of which P.8,373 million was due within one year. The major categories of indebtedness at Telmex are as follows:



| |  |  | U.S. dollar-denominated bank loans. These include a large syndicated loan facility, loans with support from export credit agencies and other loans.Our bank facilities bear
interest at specified spreads over LIBOR. The weighted average interest rate at December 31, 2004 was approximately 3.6%. We had U.S.$3,809 million in bank loans, which was equivalent to P.42,905 million, outstanding at December 31, 2004, which
includes P.5,520 million in bank loans of Embratel and a U.S.$2,425 million facility Telmex obtained in July 2004. The loan has two tranches. One tranche bears interest at LIBOR plus 0.45% and matures in 2007, and the other tranche bears interest at
LIBOR plus 0.525% and matures in 2009. Certain of our bank loans contain financial and operating covenants. The most restrictive covenants require us to maintain a consolidated ratio of EBITDA to interest expense of no less than 3.00 to 1.00 and a
consolidated ratio of total debt to EBITDA of no more than 3.75 to 1.00 (using terms defined in the credit agreements). Compliance with these covenants has not been a significant constraint on our ability to obtain financing.

| |  |  | U.S. dollar-denominated senior notes. At Telmex, we had U.S.$2,500 million aggregate principal amount of senior notes outstanding, which was equivalent to P.28,162 million at
December 31, 2004, and we issued a further U.S.$1.75 billion aggregate principal amount of senior notes in January and February 2005. As a result, Telmex has four series of senior notes outstanding:

We have repurchased in
the open market part of the 8.25% notes due in January 2006, and the outstanding balance as of March 31, 2005 was U.S.$1,199 million.



| |  |  | Peso-denominated senior notes (certificados bursátiles). We have issued senior notes from time to time in the Mexican market. Part of these notes bear interest at
fixed rates and part bear interest at specified spreads over Mexican Cetes (short-term Mexican government obligations). At December 31, 2004, we had P.7,450 million outstanding maturing from 2005 to 2012, and the weighted average interest
rate was 9.9%. On February 10, 2005, P.850 million of our peso-denominated notes matured, leaving P.6,600 million outstanding.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We also have smaller amounts of other categories of indebtedness outstanding at Telmex, including peso-denominated loans from Mexican banks, financial
leases and supplier credits for equipment financing. We rely primarily on borrowings in the Mexican and international capital markets and from international banks, although if market conditions change, we may seek currency from export credit
agencies or other sources. A number of our financing instruments are subject to either acceleration or repurchase at the holders option if there is a change of control, as defined in the respective instruments. The definitions of change of
control vary, but none of them is met so long as Carso Global Telecom or its present controlling shareholders continue to control a majority of our voting stock.



The major categories of indebtedness at Embratel are bank facilities denominated in U.S. dollars (P.5,520 million at
December 31, 2004), commercial paper denominated in reais (P.4,244 million at December 31, 2004) and bonds denominated in U.S. dollars (P.3,098 million at December 31, 2004). In November 2004, Embratel issued R$1.0 billion in commercial paper
in Brazil equivalent to P.4,244 million that bears interest at a rate of 102.3% of the CDI rate (the interest rate applicable to inter-bank certificates in Brazil) and had a term of 180 days. In early December 2003, Embratel issued U.S.$275 million
of notes, which was equivalent to P.3,098 million at December 31, 2004. The notes mature in 2008 and bear interest at an interest rate of 11% per year. These notes are fully and unconditionally guaranteed by Embratel Holdings. Since acquiring
control of Embratel, we have reduced its debt and prepaid the debt with the most restrictive terms. In the first half of 2005, Embratel completed a R$1.8 billion capital increase in which we subscribed 87.5% of the shares sold, and it used part of
the proceeds to prepay U.S.$96.3 million of its notes due 2008 at a redemption price of U.S.$106.8 million and to repay its R$1.0 billion in commercial paper.

##### Table of Contents

Embratel has a substantial amount of tax-related contingencies. If a major part of the tax disputes were
to be decided against Embratel, this could have a material effect on liquidity. See Note 12 to our consolidated financial statements.



At December 31, 2004, 84.1% of our total consolidated indebtedness was denominated in U.S. dollars, 9.7% was in Mexican pesos, 4.8% was in Brazilian
reais and 1.4% was in other currencies. Our currency hedging practices are described below.



At December 31, 2004, 60.3% of our debt obligations bore interest at floating rates. The weighted average cost of all borrowed funds, including those of
Embratel, at December 31, 2004 (including interest and reimbursement of certain lenders for Mexican taxes withheld, but excluding fees) was approximately 6.9%. The inclusion of fees in the calculation of weighted average cost of all borrowed funds
at December 31, 2004 would increase such cost by 0.3%, to 7.2%.



Hedging



Currently, our hedging activities fall into three
categories, as described below. Our hedging practices vary from time to time depending on our judgment about the level of risk and the costs of hedging.



Because our U.S. dollar-denominated indebtedness far exceeds our U.S. dollar-denominated assets and revenues, from time to time Telmex enters into hedging
transactions to protect to some degree against the short-term risks of devaluation of the Mexican peso. Gains and losses on these transactions are recognized in income as incurred. Under Mexican GAAP, we account for these transactions on an accrual
basis, and such amounts offset gains and losses on the foreign currency liabilities that are hedged. At December 31, 2004, our hedges covered liabilities of U.S.$3,220 million out of our total U.S. dollar-denominated liability of U.S.$6,721 million,
but the amount of our hedging position varies substantially from time to time. In 2004, we recognized a net charge of P.499,679 in our results of operations, reflecting the effects of exchange rate variations under our hedging agreements. See Note 8
to our consolidated financial statements. This resulted from devaluation of the U.S. dollar against the peso and especially against the real. Our hedges are short-term, typically averaging about 60 days, and will not protect us against the
long-term effects of a devaluation on our U.S. dollar-denominated indebtedness. We may stop hedging or modify our hedging practices at any time.



A substantial portion of our peso-denominated indebtedness (P.7,050 million at December 31, 2004) bears interest at floating rates. We have engaged in
extensive hedging transactions to reduce our exposure to changes in Mexican interest rates. Specifically, we have entered into interest rate swaps in which we pay interest at a fixed rate and receive interest at a floating rate, on a notional amount
in Mexican pesos or U.S. dollars. The general effect of these swaps is to replace an obligation to pay floating-rate interest on our debt with an obligation to pay fixed-rate interest. Because the peso-denominated swap market is not highly liquid,
we do not ordinarily obtain interest rate swaps that precisely match the tenors or amounts of our floating-rate liabilities. The aggregate notional amount of our swaps may be greater or less than the principal amount of our
floating-rate peso-denominated debt, and we may discontinue hedging at any time. At December 31, 2004, the aggregate notional amount of domestic interest rate swaps was P.12,390 million. At December 31, 2004, we had entered into interest rate swaps
for a total of U.S.$1,050 million for which we paid fixed rates and received six-month LIBOR rates and swaps for a total of U.S.$1,050 million for which we paid six-month LIBOR rates and received fixed rates.



Because a substantial portion of the indebtedness of Embratel is denominated
in foreign currencies, Embratel enters into hedging transactions to protect itself to some degree against the short-term risks of devaluation of the Brazilian real. At December 31, 2004, Embratel had swaps covering U.S.$323.9 million of its
indebtedness. Embratel recognized a charge of P.767,817, reflecting the effects of exchange rate variations under its hedging agreements.

Off-Balance Sheet Arrangements



We do not have any off-balance sheet arrangements of the type that we are required to disclose under Item 5.E of Form 20-F.



U.S. GAAP Reconciliation



Net income under U.S. GAAP was P.28,235 million in 2004, P.22,833 million in
2003 and P.19,425 million in 2002. Compared to Mexican GAAP, net income under U.S. GAAP was 1.4% higher in 2004, 3.3% lower in 2003 and 9.2% lower in 2002.



There are certain differences between Mexican GAAP and U.S. GAAP that affect our net income and stockholders equity. The most significant in its
effect on net income is the difference in how the carrying value of plant, property and equipment is restated to reflect effects of inflation. Under Mexican GAAP, we restate fixed assets of non-Mexican origin based on the rate of inflation in the
country of origin and the prevailing exchange rate at the balance sheet date, while under U.S. GAAP we use the Mexican inflation rate.



Other differences that affected net income relate to accounting for costs of pension and seniority premium plans, capitalization of interest on assets
under construction, accounting for swaps and other derivatives, deferred profit-sharing and our stock option plan. The differences in stockholders equity under Mexican GAAP and U.S. GAAP reflect these same matters. For a discussion of the
principal differences between Mexican GAAP and U.S. GAAP, see Note 19 to our consolidated financial statements.



Use of Estimates in Certain Accounting Policies



In preparing our financial statements, we make estimates concerning a variety of matters. Some of these matters are highly uncertain, and our estimates
involve judgments we make based on the information available to us. In the discussion below, we have identified several of these matters for which our financial presentation would be materially affected if either (a) we used different estimates that
we could reasonably have used or (b) in the future we change our estimates in response to changes that are reasonably likely to occur.



The discussion addresses only those estimates that we consider most important based on the degree of uncertainty and the likelihood of a material impact
if we used a different estimate. There are many other areas in which we use estimates about uncertain matters, but the reasonably likely effect of changed or different estimates is not material to our financial presentation.



Estimated Useful Lives of Plant, Property and Equipment



We estimate the useful lives of particular classes of plant,
property and equipment in order to determine the amount of depreciation expense to be recorded in each period. Depreciation expense is a significant element of our costs, amounting in 2004 to P.22,602 million, or 23.8% of our operating costs and
expenses, under Mexican GAAP, and P.25,410 million, or 25.2% of our operating costs and expenses, under U.S. GAAP. See Notes 4 and 19 to our consolidated financial statements.



The estimates are based on historical experience with similar assets, anticipated technological changes and other factors,
taking into account the practices of other telecommunications companies. We



52

##### Table of Contents

review estimated useful lives each year to determine whether they should be changed, and at times we have changed them
for particular classes of assets. We may shorten the estimated useful life of an asset class in response to technological changes, changes in the market or other developments. This results in increased depreciation expense, and in some cases it can
result in our recognizing an impairment charge to reflect a write-down in value. For example, in 2003, we reduced the useful lives of certain assets to reflect technological changes, which resulted in a P.887 million increase in depreciation
expense. The same kinds of developments can also lead us to lengthen the useful life of an asset class, resulting in reduced depreciation expense. For example, in both 1999 and 2000, we lengthened the useful lives of certain categories of fixed
assets.



Employee Pensions and Seniority
Premiums



We recognize liabilities on our balance
sheet and expenses in our income statement to reflect our obligations to pay employees under defined benefit retirement and seniority premium plans. The amounts we recognize are determined on an actuarial basis that involves many estimates. In 2004,
we recognized net period cost relating to these obligations of P.4,390 million under Mexican GAAP and P.3,620 million under U.S. GAAP.



We use estimates in three specific areas that have a significant effect on these amounts: (a) the real discount rates that we use to calculate the present
value of our future obligations, (b) the real rate of increase in salaries that we assume we will observe in future years and (c) the rate of return we assume our pension fund will achieve on its investments. The assumptions we have applied are
identified in Note 7 (Mexican GAAP) and Note 19 (U.S. GAAP) to our consolidated financial statements. These estimates are based on our historical experience, on current conditions in the financial markets and on our judgments about the future
development of our salary costs and the financial markets. We review the estimates each year, and if we change them, our reported expense for pension costs may increase or decrease.



Our liability for future pensions and seniority premiums is also affected by our estimate of the number of retired employees
and our pension fund is affected by the estimated rate of return on investments. Actual results may vary from these estimates. In 2004, an actuarial loss of P.7,704 million was attributable to the increase in the projected benefit obligation due
primarily to: (i) a greater number of employees retiring than had been estimated at the beginning of the year, (ii) modification of the estimated retirement age based on our experience with retiring personnel and (iii) updating of the mortality
rates. In addition, the return on investments of our pension fund amounted to a gain of P.9,394 million in 2004, due to the gains by plan assets on the Mexican Stock Exchange and the increase in fixed-yield interest rates. As of December 31,
2004, 55.6% of fund assets consisted of peso-denominated fixed-income securities and 44.4% consisted of variable-income securities of Mexican companies. The fund has experienced volatile returns on its investments in equity securities, which
resulted in net losses on plan assets in prior years. Our actuarial assumptions as of December 31, 2004 include an assumed annual return of 6.8% in real terms on plan assets.



Allowance for Doubtful Accounts



We maintain an allowance for doubtful accounts based on our estimates of losses we may experience because our customers or
other telecommunications carriers do not pay the amounts they owe us. At December 31, 2004, the amount of the allowance was P.11,398 million. For our customers, we perform a statistical analysis based on our past experience, current delinquencies
and economic trends. For carriers, we make individual estimates that may reflect our evaluation of pending disputes over amounts owed. Our allowance could prove insufficient if our statistical analysis of our customer receivables is inadequate, or
if one or more carriers refuse or are unable to pay us. See Note 3 to our consolidated financial statements.

Revenues from Prepaid Telephone Cards



We recognize revenues from the sale of our prepaid telephone service cards
based on our estimate of the usage of time covered by the prepaid card. We estimate the period for usage of prepaid telephone cards in accordance with available statistics that reflect the total usage of cards and the total amounts sold. The cards
do not have an expiration date.



The prepaid telephone card
contains a data chip that tracks the number of units of service the card can provide. Each time the card is used, the telephone equipment records the number of units used and reduces the number of available units on the chip. When the
number of available units in the chip is reduced to zero, it ceases to function. We track the aggregate number of units sold and the aggregate number of units used, but we do not track the number of units used on a card-by-card basis.



Impairment of Long-Lived Assets



In addition, we review our property, plant and equipment for impairment
whenever events or circumstances indicate that the carrying amount may not be recoverable. To estimate the fair value of long-lived assets, we typically make various assumptions about the future prospects for the business that the asset relates to,
consider market factors specific to that business and estimate future cash flows to be generated by that business. Based on these assumptions and estimates, we determine whether we need to take an impairment charge to reduce the value of the asset
stated on our balance sheet to reflect its estimated fair value. Assumptions and estimates about future values and remaining useful lives are complex and often subjective. They can be affected by a variety of factors, including external factors such
as industry and economic trends, and internal factors such as changes in our business strategy and our internal forecasts. Different assumptions and estimates could materially impact our reported financial results. More conservative assumptions of
the anticipated future benefits from these businesses could result in impairment charges, which would decrease net income and result in lower asset values on our balance sheet. Conversely, less conservative assumptions could result in smaller or no
impairment charges, higher net income and higher asset values.



Realization of Net Deferred Tax Assets



The recognition of net deferred tax assets on temporary differences in our non-Mexican subsidiaries, mainly due to Brazilian tax losses and to the negative basis for calculating social contribution in Brazil, is supported by the history of
taxable income and Embratels estimate of future profitability. Bulletin D-4 establishes the conditions for recording and maintenance of these deferred assets. Based on Embratels financial projections, we believe that these assets will be
realized over a period of ten years. A future change in these projections of profitability could result in the need to record a valuation allowance against these net deferred tax assets, resulting in a negative impact on future results.

Provision for Contingencies



We are subject to proceedings, lawsuits and other claims related to tax, labor and civil matters. We are required to assess
the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is made after careful analysis of each
individual matter, based on advice of our legal counsel. We record provisions for contingencies only when we believe that it is probable that we will incur a loss in connection with the matter in dispute. In a number of significant tax disputes with
the Brazilian tax authorities, we have recorded no provisions because we do not believe a loss is probable. The total balance of probable losses is recorded as a current liability, because it is not possible to estimate the time required to reach a
settlement. The required reserves for these and other contingencies may change in the future due to new developments in each matter or changes in approach, such as a change in settlement strategy in dealing with these matters. Such changes could
have a negative impact on future results and cash flows.



Item 6. Directors and Officers of Registrant



Directors



Management of our business is
vested in the Board of Directors. Our bylaws provide for the Board of Directors to consist of at least five directors and up to an equal number of alternate directors. A majority of the directors and a majority of the alternate directors must be
Mexican nationals and elected by Mexican shareholders. Directors are elected by a majority of the holders of the AA Shares and A Shares voting together, provided that any holder or group of holders of at least 10% of the total AA Shares and A Shares
is entitled to name one of such directors and one of such alternate directors, and two directors and two alternate directors are elected by a majority vote of the holders of L Shares. Each alternate director may attend meetings of the Board of
Directors and vote in the absence of a corresponding director. Directors and alternate directors are elected at each annual ordinary general meeting of shareholders and each annual ordinary special meeting of holders of L Shares, and each serves
until a successor is elected and takes office. Pursuant to our bylaws and Mexican law, at least 25% of our directors and 25% of our alternate directors must be independent, as defined under the Mexican Securities Market Law (Ley del Mercado de
Valores). In order to have a quorum for a meeting of the Board of Directors, a majority of those present must be Mexican nationals.



Carso Global Telecom and SBC International have agreed to vote for the number of directors and alternate directors named by Carso Global Telecom and SBC
International, respectively, considering their respective share ownership.

Executive Committee



Our bylaws provide that the executive committee may generally exercise the powers of the Board of Directors. The Board of Directors is also required to
consult the executive committee before deciding on certain matters set forth in the bylaws, and the executive committee must provide its views within 10 calendar days following a request from the Board of Directors.



The executive committee is elected from among the directors and alternate
directors by a majority vote of the AA Shares, A Shares and A Share ADSs voting together. Under the agreement entered into in December 2000 between Carso Global Telecom and SBC International, the executive committee consists of four members. The
majority of its members must be of Mexican nationality and elected by Mexican shareholders. Carso Global Telecom and SBC International have agreed to vote for three members named by Carso Global Telecom and one member named by SBC International. The
current members of the executive committee are Jaime Chico Pardo, Juan Antonio Pérez Simón and Carlos Slim Domit, all named by Carso Global Telecom and various other Mexican investors, and Richard P. Resnick, named by SBC
International. The current alternate members of the executive committee are Antonio Cosío Ariño, José Humberto Gutiérrez-Olvera Zubizarreta and Marco Antonio Slim Domit, all named by Carso Global Telecom and various other

Mexican Code of Best Corporate Practices



In
January 2001, a Mexican commission of business leaders, with the support of the Mexican Banking and Securities Commission (Comisión Nacional Bancaria y de Valores, or the CNBV), issued a Code of Best Corporate Practices
(Código de Mejores Prácticas Corporativas) for publicly traded Mexican companies, recommending certain actions with respect to various areas of corporate governance. Following these recommendations, in February 2001, the Board
of Directors created an audit committee and an evaluation and compensation committee. The Mexican Securities Market Law was amended effective June 2001 to require that all publicly traded Mexican companies have an audit committee. In March 2003, the
CNBV codified certain provisions of the Code of Best Corporate Practices, requiring among other things, increased responsibilities for audit committees.While compliance with the Code of Best Corporate Practices is voluntary, the CNBV
requires companies listed on the Mexican Stock Exchange to file a report, on a yearly basis, regarding their compliance with the Code of Best Corporate Practices. Our report on compliance with the Code of Best Corporate Practices is on file with the
CNBV and the Mexican Stock Exchange. The Mexican Congress is considering significant changes to the Mexican Securities Market Law with a focus on increasing its adherence to international standards, including increased protections for minority
shareholders.

outstanding AA Shares and A Shares voting together may elect one or more statutory auditors (comisarios) and corresponding alternate statutory auditors. The primary role of the statutory auditors is to report to the holders of AA Shares and A
Shares at the annual ordinary general meeting regarding the accuracy of the financial information presented to such holders by the Board of Directors. The statutory auditors are also authorized to, among other things, (a) call ordinary or
extraordinary general shareholders meetings, (b) place items on the agenda for meetings of shareholders or the Board of Directors, (c) attend meetings of shareholders or the Board of Directors and (d) generally monitor our affairs. The
statutory auditors also receive monthly reports from the Board of Directors regarding material aspects of our affairs, including our financial condition. The current statutory auditor and alternate statutory auditor are:

Compensation of Directors and
Officers



For the year ended December 31, 2004, the
aggregate compensation of all of our directors, alternate directors and executive officers paid for services in all capacities was approximately P.87.3 million. Each director or alternate director received an average fee of P.47.2 thousand (nominal)
for each meeting of the Board of Directors attended in 2004. Members of committees of the Board of Directors received an average fee of P.14.7 thousand (nominal) for each committee meeting attended in 2004.



In 2005, we terminated our stock option plan for our executive officers. In
January 2003, we granted options to purchase an aggregate of 11.7 million L Shares at P.11.17 per L Share, which were exercisable over a period of nearly four years from the date of grant. We subsequently reduced this period to two years. In January
2004, we granted options to purchase an aggregate of 9.0 million L Shares at P.13.45 per L Share, which were exercisable for a period of nearly four years from the date of grant. We subsequently reduced this period to one year. In accordance with
Mexican GAAP, we do not recognize any compensation expense as a result of granting stock options to our executive officers.

At December 31, 2004, the Telephone Workers Union of Mexico (known by its Spanish acronym, STRM) represented approximately 58.0% of our employees,
and members of other unions represented approximately 9.7% of our employees. All management positions are held by non-union employees. Salaries and certain benefits for unionized personnel are renegotiated every year and the collective bargaining
agreements with our unionized employees are renegotiated every two years. In April 2005, we and the STRM agreed to a 4.6% nominal increase in basic wages and a 1.5% nominal increase in benefits.

Item 7. Major Shareholders and Related Party Transactions



MAJOR SHAREHOLDERS



The AA Shares
represented 35.1% of the total capital stock and 94.2% of the full voting shares (AA shares and A Shares) as of May 17, 2005. The AA Shares are owned by (1) Carso Global Telecom, (2) SBC International, a subsidiary of the U.S. telecommunications
company SBC Communications, Inc. and (3) various other Mexican investors. Carso Global Telecom holds interests in telecommunications and was spun off from Grupo Carso in 1996. Carso Global Telecom may be deemed to control us. According to reports of
beneficial ownership of our shares filed with the SEC, Carso Global Telecom is controlled by Mr. Carlos Slim Helú and members of his immediate family.



Carso Global Telecom and SBC International are parties to an agreement entered into in December 2000 providing for certain matters relating to their
ownership of AA Shares. Among other things, the agreement subjects certain transfers of AA Shares by either party to a right of first offer in favor of the other party, although the right of first offer does not apply to the conversion of AA Shares
to L Shares, as permitted by our bylaws, or the subsequent transfer of L Shares. The agreement also provides for the composition of the Board of Directors and the executive committee (see Item 6. Directors and Officers of
RegistrantDirectorsand Item 6. Directors and Officers of RegistrantExecutive Committee) and for each party to enter into a Management Services Agreement with us (see Related Party Transactions).



The following table identifies each owner of five percent or more of any
class of our shares as of May 17, 2005, unless otherwise indicated. Except as described below, we are not aware of any holder of five percent or more of any class of our shares.

RELATED PARTY TRANSACTIONS



General



We engage in a variety of transactions in the ordinary
course of business with affiliates. Pursuant to our bylaws and Mexican law, the audit committee of our Board of Directors must express an opinion on, and our Board of Directors has exclusive power to approve, any transaction with a related party
that is outside the ordinary course of our business.



Our
transactions with affiliates include purchasing network construction services and materials from a subsidiary of Grupo Condumex, S.A. de C.V. and insurance and bank services from Grupo Financiero Inbursa. In addition, we sell network construction
materials to Grupo Condumex and provide certain services to Grupo Carso and Grupo Financiero Inbursa. Grupo Condumex and Grupo Financiero Inbursa are under common control with Carso Global Telecom, and several of their directors are also members of
our Board of Directors. See Item 6. Directors and Officers of RegistrantDirectors. The aggregate amount of our purchases from affiliates was P.9,041 million in 2004, P.8,028 million in 2003 and P.7,959 million in 2002. The aggregate
amount of our sales to these affiliates was P.989.1 million in 2004, P.685.8 million in 2003 and P.585.5 million in 2002. We believe that the prices paid in these transactions are comparable to those that would be obtained in arms length
negotiations with unaffiliated parties.



From time to time we
make investments together with affiliated companies, sell our investments to affiliates and buy investments from affiliates. Some of these transactions are described below.



| |  |  | In June 2001, we acquired a 45% interest in Grupo Telvista, S.A. de C.V., whose principal asset is Telvista, Inc. (Telvista), a U.S. telemarketing company, for U.S.$47.0 million. We
made this investment together with our affiliates, the other shareholders of Telvista, América Móvil (45%) and Grupo Carso (10%).
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In April 2004, we acquired a 60% indirect interest in Techtel from América Móvil for U.S.$75 million.
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | We owned a 50% interest in Technology and Internet L.L.C., a company that invests in e-commerce enterprises in the United States and Latin America. We made this investment together
with our affiliates, América Móvil (40.3%) and Grupo Financiero Inbursa (9.7%). On June 21, 2005, we sold our entire interest in Technology and Internet L.L.C. to Grupo Condumex.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We owned approximately 25.6 million shares of common stock of MCI. Other parties that may be deemed to be under common control with us held an additional interest. In May 2005, we
and the other parties that may be deemed to be under common control with us sold all shares held.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We also pay fees to Carso Global Telecom and SBC International for consulting and management services, pursuant to agreements with each party negotiated
on behalf of us by a special committee of directors unaffiliated with any of the parties. The current agreements with Carso Global Telecom and SBC International were renewed for the period beginning January 1, 2005 on substantially similar terms to
prior agreements. We paid to both companies an aggregate amount of U.S.$29 million in 2004, U.S.$29 million in 2003 and U.S.$29 million in 2002.



Executives of Carso Global Telecom periodically use our corporate airplane for business purposes. Carso Global Telecom pays us market rates for this
service.

We are working with Grupo Financiero Inbursa on the continued joint development and promotion of the
Count on Telmex card. With respect to the debit feature of the card, Grupo Financiero Inbursa manages the cash balances, and we and Grupo Financiero Inbursa divide the related earnings and costs. With respect to the credit feature of the card, Grupo
Financiero Inbursa is responsible for, and bears all risks related to, the credit card operations. We are responsible for basic logistical support and invoicing and collection services in connection with the card.



Transactions between Telmex and América Móvil



América Móvil has had in recent periods a variety of
contractual relationships with us and with our subsidiaries. Because both we and América Móvil, the leading wireless operator that was established in a spin-off from us in 2000, provide telecommunications services in the same
geographical markets, we have extensive operational relationships. These include interconnection between our respective networks; use by América Móvil of our private circuits; our provision of long distance service to América
Móvils customers; use of facilities, particularly for the co-location of equipment on premises we own; and use by each of the services provided by the other. These operational relationships are subject to a variety of agreements, which
for the most part were in place prior to the spin-off and were not significantly modified as a result of the spin-off. Many of them are also subject to specific regulations governing all telecommunications operators. Interconnection fees represent
the largest component of amounts paid under these agreements. In 2004, the aggregate amount we paid América Móvil for interconnection fees totaled P.10,319 million, and the aggregate amount paid to us by América Móvil
totaled P.4,318 million, primarily for use of our private circuits and long distance services. The terms of the arrangements with América Móvil are generally similar to those on which each company does business with other, unaffiliated
parties.



In addition, we distribute América
Móvils handsets and prepaid cards on commercial terms similar to those given to other cellular distributors.



Transactions between Embratel and Related Parties



Embratel engages in a variety of transactions in the ordinary course of business with our subsidiaries and with other companies that may be deemed to be
under common control with us.



Embratel completes international
traffic from our subsidiaries and subsidiaries of América Móvil in Mexico, Chile and Argentina. Our subsidiaries and subsidiaries of América Móvil in Mexico, Chile and Argentina complete international traffic from
Embratel.



Because both Embratel and América
Móvils subsidiary, Telecom Americas S.A., which operates under the brand Claro, provide telecommunications services in the same geographical markets, they have extensive operational relationships. Embratel originates mobile domestic and
international long distance traffic from Claro and terminates mobile domestic and international long distance traffic to Claro. Embratel also transports Claros traffic and leases lines to Claro.



Through its subsidiary, BrasilCenter, Embratel provides call center services
to Claro and Net. Embratel also leases access facilities from Telmex do Brasil.



The terms of Embratels arrangements with our subsidiaries and with other companies that may be deemed to be under common control with us are generally similar to those on which each company does business with
other, unaffiliated parties.



In November 2004, Embratel
entered into a U.S.$75 million credit agreement with Banco Inbursa, Institución de Banca Múltiple, Grupo Financiero Inbursa, a subsidiary of Grupo Financiero Inbursa. The agreement had terms comparable to those of three other
loans Embratel received from unaffiliated parties in November and December 2004.

LEGAL PROCEEDINGS



Telmex



There were a number of pending proceedings before the Mexican courts in
which we or our competitors had challenged determinations or regulations issued by Cofetel, most of which were withdrawn as a result of December 2000 agreements with certain competitors. We are also involved in legal proceedings in the ordinary
course of our business, none of which is material. In addition, we are in the process of appealing various proceedings brought by our competitors alleging anticompetitive practices by us before competition authorities in Mexico. The proceedings
could result in fines by the authorities and subsequent civil actions by our competitors, but we believe that a negative outcome of these proceedings would not be material on an aggregate basis.



The Mexican Social Security Institute (Instituto Mexicano del Seguro
Social) conducted an audit of our social security obligations for the period from 1997 through 2001. Following the audit, we were ordered to pay a total of approximately P.330 million (nominal value) consisting of past due obligations, penalties
and accrued interest as of July 2, 2003. We have appealed these rulings to the Federal Administration and Taxation Court (Tribunal Federal de Justicia Fiscal y Administrativa) and, in accordance with Mexican law, have deposited a bond
guaranteeing the amount alleged to be owed. Although we believe the basis for our appeal is well founded, there can be no assurance that we will prevail.



Embratel



Embratel has a substantial amount of tax-related and other contingencies. See Note 12 to our consolidated financial statements. Although Embratel believes
the cases to which these contingencies relate are well founded, there is no guarantee that it will prevail in these cases.



Brazilian value-added goods and services tax (ICMS)



Embratel has received a number of fines for non-payment of ICMS on international outbound traffic and certain bundled
services that are considered exempt or non-taxable for ICMS purposes. Embratel recorded a provision for P.368 million for losses considered probable but did not record a provision for P.3.8 billion, which corresponds to the claims in which Embratel
expects to prevail.



In July 2002, Star One received two
assessments by the tax authorities in the state of Rio de Janeiro for payment of ICMS in the amount of approximately P.1.0 billion related to Internet services and satellite use. In March 2004, Star One was required to pay approximately P.84.0
million in the Brazilian Federal District for ICMS not paid on satellite use and other obligations. Star One determined that it faces little risk of losing these suits so it has not recorded a provision for such amounts in its financial statements.

Income Tax on Inbound International Income



Embratel believes that the foreign operating income from telecommunications
services (inbound traffic) is not subject to taxation. In connection with this matter, in late March 1999, the Brazilian Federal Tax Agency, or SRF, assessed Embratel approximately P.1.2 billion for failing to pay the related income tax for the
years 1996 and 1997. Embratels appeal of this decision is still pending.



In June 1999, Embratel was further assessed for non-payment of income tax on net foreign source income for 1998 amounting to approximately P.273 million. Embratel considers the probability of loss unlikely, so no
provisions have been recorded in the financial statements for the claim.



Brazilian Social Welfare Tax on Service Exports (PIS)



In August 2001, the SRF issued a tax claim against Embratel totaling approximately P.675 million for payment of PIS prior to 1995, which had been offset
in accordance with Brazilian tax law. Embratels management evaluated the probability of a loss, and determined that no provision would be recorded in the financial statements for the claim.



Brazilian Finance Tax for Service Export Security Tax (COFINS)



There is also a P.1,451 million claim against Embratel
related to the COFINS exemption on the exportation of telecommunication services for revenues through the end of 1999. Embratel argued that the government auditor made several errors in the computation of this tax and, consequently, this tax was
later reduced by approximately P.934 million. A new decision at the administrative level has restated this tax to an amount of approximately P.1,004 million. Embratel has appealed this decision to a higher administrative level, and this appeal is
still pending.



Disputes with third parties



Embratel is involved in a variety of additional litigation
and administrative proceedings that have arisen in the ordinary course of business. Various disputes are in an advanced stage of the litigation process, and Embratel may lose at least some of the cases. Embratel has recorded a provision of P.700
million (restated) for unfavorable rulings. For other claims totaling P.62.8 million, Embratel provided guarantee deposits of P.46.0 million.

The
declaration, amount and payment of dividends are determined by majority vote of the holders of AA Shares and A Shares, generally on the recommendation of the Board of Directors, and will depend on our results of operations, financial condition, cash
requirements, future prospects and other factors deemed relevant by the holders of AA Shares and A Shares. Accordingly, we cannot assure you that we will continue to pay dividends or that future dividends will be comparable to historical dividends.
Our bylaws provide that holders of the AA Shares, the A Shares and the L Shares share equally on a per-share basis in dividend payments and other distributions.

TRADING ON THE MEXICAN STOCK EXCHANGE



The Mexican Stock Exchange (Bolsa Mexicana de Valores, S.A. de C.V.), located in Mexico City, is the only stock exchange in Mexico. Founded in 1907, it is organized as a corporation whose shares are held by 26 brokerage firms, which
are exclusively authorized to trade on the Mexican Stock Exchange. Trading on the Mexican Stock Exchange takes place principally through automated systems, which are open between the hours of 8:30 a.m. and 3:00 p.m., Mexico City time, each business
day. Trades in securities listed on the Mexican Stock Exchange can also be effected off the exchange. The Mexican Stock Exchange operates a system of automatic suspension of trading in shares of a particular issuer as a means of controlling
excessive price volatility, but under current regulations this system does not apply to securities such as the A Shares or the L Shares that are directly or indirectly (for example, through American Depositary Shares) quoted on a stock exchange
(including for these purposes NASDAQ) outside Mexico.



Settlement is effected two business days after a share transaction on the Mexican Stock Exchange. Deferred settlement, even by mutual agreement, is not permitted without the approval of the Mexican National Securities Commission. Most
securities traded on the Mexican Stock Exchange, including those of Telmex, are on deposit with S.D. Indeval, S.A. de C.V., a privately owned securities depositary that acts as a clearinghouse for Mexican Stock Exchange transactions.

Item 10. Additional Information



BYLAWS



Set forth below is a
brief summary of certain significant provisions of our bylaws and Mexican law. The full text of our bylaws has been filed as an exhibit to this Annual Report.For a description of the provisions of our bylaws relating to our Board of
Directors, committees of the Board of Directors and statutory auditors, see Item 6. Directors and Officers of Registrant.



On March 19, 2003, the CNBV published new general rules, or the Rules, for issuers, which codify the principal rules applicable to issuers and public
offerings. The Rules increased the obligations and responsibilities of the audit committee by requiring the committees opinion to delist or cancel the registration of the shares of a company and to authorize any changes to the accounting
policies and practices, among other important provisions.



Organization and
Register



Telmex is a sociedad anónima de
capital variable organized in Mexico under the Mexican Companies Law (Ley General de Sociedades Mercantiles). It is registered with the Public Registry of Commerce of Mexico City under the number 5229.



Share Capital



Our capital stock comprises Series AA Shares, without par value, Series A Shares, without par value and Series L Shares,
without par value. All of the outstanding shares are fully paid and non-assessable.



AA Shares and A Shares have full voting rights. Holders of L Shares may vote only in limited circumstances as described under Voting Rights. The rights of holders of all series of capital stock are
otherwise identical except for limitations on non-Mexican ownership of AA Shares. The AA Shares, which must always represent at least 51% of the combined AA Shares and A Shares, may be owned only by holders that qualify as Mexican investors as
defined in the Foreign Investment Law and our bylaws. See Limitations on Share Ownership.



Each AA Share or A Share may be exchanged at the option of the holder for one L Share, provided that the AA Shares may never represent less than 20% of
our outstanding capital stock or less than 51% of our combined AA Shares and A Shares. As of December 31, 2004, the AA Shares represented 34.3% of our outstanding capital stock and 94.2% of our combined AA Shares and A Shares.



Each L Share is exchangeable at the option of the holder for one AA Share by
delivering the L Share certificate to our treasury for cancellation and receiving the corresponding AA Share certificate. The right to exchange is subject to limitations on non-Mexican ownership of AA Shares and to the requirement that the AA Shares
and A Shares together may never represent more than 51% of our outstanding capital stock. As of December 31, 2004, the AA Shares and A Shares together represented 36.5% of our outstanding capital stock.

##### Table of Contents

Voting Rights



Each AA Share and A Share entitles the holder thereof to one vote at any meeting of our shareholders. Each L Share entitles the holder to one vote at any
meeting at which holders of L Shares are entitled to vote. Holders of L Shares are entitled to vote only to elect two members of the Board of Directors and the corresponding alternate directors and on the following matters:



| |  |  | the extension of Telmexs term of duration;
| | - |  | -------------------------------------------



| |  |  | the transformation of Telmex from one type of company to another;
| | - |  | -----------------------------------------------------------------



| |  |  | any merger in which Telmex is not the surviving entity or any merger with an entity whose principal corporate purposes are different from those of Telmex;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | removal of our shares from listing on the Mexican Stock Exchange or any foreign stock exchange; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | any action that would prejudice the rights of holders of L Shares.
| | - |  | ------------------------------------------------------------------



A resolution on any of the specified matters requires the affirmative vote of both a majority of all outstanding shares and a majority of the AA Shares and the A Shares
voting together.



Under Mexican law, holders of shares of any
series are also entitled to vote as a class on any action that would prejudice the rights of holders of shares of such series and a holder of shares of such series would be entitled to judicial relief against any such action taken without such a
vote. The determination whether an action requires a class vote on these grounds would initially be made by the Board of Directors or other party calling for shareholder action. A negative determination would be subject to judicial challenge by an
affected shareholder, and a court would ultimately determine the necessity for a class vote. There are no other procedures for determining whether a proposed shareholder action requires a class vote, and Mexican law does not provide extensive
guidance on the criteria to be applied in making such a determination.



Shareholders Meetings



General
shareholders meetings may be ordinary meetings or extraordinary meetings. Extraordinary general meetings are those called to consider certain matters specified in Article 182 of the Mexican Companies Law, including, principally, amendments of
the bylaws, liquidation, merger and transformation from one type of company to another, as well as to consider the removal of our shares from listing on the Mexican Stock Exchange or any foreign stock exchange. General meetings called to consider
other matters are ordinary meetings. The two directors elected by the holders of L Shares are elected at a special meeting of holders of L Shares. All other matters on which holders of L Shares are entitled to vote would be considered at an
extraordinary general meeting. Holders of L Shares are not entitled to attend or address meetings of shareholders at which they are not entitled to vote.



A special meeting of the holders of L Shares must be held each year for the election of directors. An ordinary general meeting of the holders of AA Shares
and A Shares must be held each year to consider the approval of the financial statements for the preceding fiscal year, to elect directors and statutory auditors and to determine the allocation of the profits of the preceding year.

##### Table of Contents

The quorum for an ordinary general meeting of the AA Shares and A Shares is 50% of such shares, and
action may be taken by a majority of the shares present. If a quorum is not available, a second meeting may be called at which action may be taken by a majority of the AA Shares and A Shares present, regardless of the number of such shares. Special
meetings of holders of L Shares are governed by the same rules applicable to ordinary general meetings of holders of AA Shares and A Shares. The quorum for an extraordinary general meeting at which holders of L Shares may not vote is 75% of the AA
shares and A Shares, and the quorum for an extraordinary general meeting at which holders of L Shares are entitled to vote is 75% of the outstanding capital stock. If a quorum is not available in either case, a second meeting may be called and
action may be taken, provided a majority of the shares entitled to vote is present. Whether on first or second call, actions at an extraordinary general meeting may be taken by a majority vote of the AA Shares and A Shares outstanding and, on
matters which holders of L Shares are entitled to vote, a majority vote of all the capital stock.



Holders of 20% of our outstanding capital stock may have any shareholder action set aside by filing a complaint with a court of law within 15 days after
the close of the meeting at which such action was taken and showing that the challenged action violates Mexican law or our bylaws. In addition, any holder of our capital stock may bring an action at any time within five years challenging any
shareholder action. Relief under these provisions is only available to holders:



| |  |  | who were entitled to vote on, or whose rights as shareholders were adversely affected by, the challenged shareholder action; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | whose shares were not represented when the action was taken or, if represented, were voted against it.
| | - |  | ------------------------------------------------------------------------------------------------------



Shareholders meetings may be called by the Board of Directors, its chairman, the statutory auditors or a court. The
Board of Directors or the statutory auditors may be required to call a meeting of shareholders by the holders of 10% of the outstanding capital stock. Notice of meetings must be published in the Diario Oficial (Official Gazette) or a
newspaper of general circulation in Mexico City at least 15 days prior to the meeting. In order to attend a meeting, shareholders must deposit their shares with us at our office in Mexico City, with a Mexican or foreign banking institution or with a
Mexican exchange broker. If so entitled to attend the meeting, a shareholder may be represented by proxy. The depositary for the L Share ADSs and the A Share ADSs does not satisfy this requirement, so ADS holders are not entitled to attend
shareholder meetings. ADS holders must exercise their voting rights through the depositary.



Dividend Rights



At the
annual ordinary general meeting of holders of AA Shares and A Shares, the Board of Directors submits our financial statements for the previous fiscal year, together with a report thereon by the Board of Directors, to the holders of AA Shares and A
Shares for approval. The holders of AA Shares and A Shares, once they have approved the financial statements, determine the allocation of our net profits for the preceding year. They are required by law to allocate 5% of such net profits to a legal
reserve, which is not thereafter available for distribution except as a stock dividend, until the amount of the legal reserve equals 20% of our capital stock. The remainder of net profits is available for distribution.



All shares outstanding at the time a dividend or other distribution is
declared are entitled to participate in such dividend or other distribution.

##### Table of Contents

Limitation on Capital Increases



Our bylaws require that any capital increase be represented by new shares of each series in proportion to the number of
shares of each series outstanding.



Preemptive Rights



In the event of a capital increase, a holder of existing shares of a given
series has a preferential right to subscribe for a sufficient number of shares of the same series to maintain the holders existing proportionate holdings of shares of that series. Preemptive rights must be exercised within 30 calendar days
following the publication of notice of the capital increase in the Diario Oficial(Official Gazette) and a newspaper of general circulation in Mexico City. Under Mexican law, preemptive rights cannot be traded separately from the
corresponding shares that give rise to such rights. As a result, there is no trading market for the rights in connection with a capital increase. Holders of ADSs may exercise preemptive rights only through the depositary. We are not required to take
steps that may be necessary to make this possible.



Limitations on Share
Ownership



Ownership by non-Mexicans of shares of Mexican
enterprises in certain economic sectors, including telephone services, is regulated by the Foreign Investment Law and the Regulations thereunder. The National Commission on Foreign Investment is responsible for administration of the Foreign
Investment Law and Regulations. In order to comply with restrictions on the percentage of their capital stock that may be owned by non-Mexican investors, Mexican companies typically limit particular classes of their stock to Mexican ownership. Under
the Foreign Investment Law, a trust for the benefit of one or more non-Mexican investors may qualify as Mexican if the trust meets certain conditions that will generally ensure that the non-Mexican investors do not determine how the shares are
voted.



Non-Mexican investors are not permitted to own more
than 49% of the capital stock of a Mexican corporation engaged in the telephone business. Pursuant to a decision of the Foreign Investment Commission dated August 10, 1990, the L Shares of Telmex, because of their limited voting rights, are not
taken into account in determining compliance with this restriction and accordingly are not subject to Mexican ownership restrictions. The A Shares are also unrestricted. The AA Shares, however, which must always represent at least 51% of the
combined AA Shares and A Shares, may be owned only by holders that qualify as Mexican investors as defined in the Foreign Investment Law and our bylaws. A holder that acquires AA Shares in violation of the restrictions on non-Mexican ownership will
have none of the rights of a shareholder with respect to those AA Shares. As a consequence of these limitations, a non-Mexican investor cannot under Mexican law own AA Shares except through a trust that effectively neutralizes the votes of
non-Mexican investors.



Pursuant to the Foreign Investment Law
and Regulations, we have registered any foreign owner of our shares, and the depositary with respect to the ADSs representing our shares, with the National Registry of Foreign Investment.



In addition, pursuant to the Foreign Investment Law and Regulations, our Mexican shareholders retain the power to determine
our administrative control and management.



Foreign states are
prohibited under the General Communications Law from directly or indirectly owning shares of Telmex. The Telecommunications Regulations provide, however, that foreign state-owned enterprises organized as separate entities with their own assets may
own minority interests in Telmex or any number of shares with limited voting rights. Ownership of A Shares or L Shares by such foreign state-owned companies, or by pension or retirement funds organized for the benefit of employees of state,
municipal or other Mexican governmental agencies, is not considered direct or indirect ownership by foreign states for the purposes of the General Communications Law.

Restrictions on Certain Transactions



Our bylaws provide that any acquisition or transfer by us of more than 10% of our issued and outstanding shares, effected in
one or more transactions by any person or group of persons acting in concert, requires prior approval by our Board of Directors.



Restrictions on Deregistration in Mexico



Our shares are registered with the National Registry for Securities, as required under the Securities Market Law and regulations issued by the CNBV. If we
wish to cancel our registration, or if it is cancelled by the CNBV, the stockholders having the majority of the ordinary shares or that may, on any basis, impose decisions at shareholders meetings, or appoint the majority of the Board of
Directors of Telmex at that time will be required to make a public offer to purchase all outstanding shares prior to such cancellation. Unless the CNBV authorizes otherwise, the offer price will be the higher of: (i) the average of the closing price
during the previous 30 days on which the shares may have been quoted, or (ii) the book value of the shares in accordance with the most recent quarterly report submitted to the CNBV and to the Mexican Stock Exchange. In order to comply with the
Rules, at the extraordinary shareholders meeting held in April 30, 2003, we amended certain articles of our bylaws. Some of the amendments were made to comply with certain new requirements for the delisting and cancellation of the registration
of the shares of the company. As a result, our bylaws now provide that if, after the public offer is concluded, there are still outstanding shares held by the general public, the shareholders that control Telmex will be required to create a trust
for a period of six months, into which such controlling shareholders will be required to contribute funds in an amount sufficient to purchase, at the same price as the offer price, the number of outstanding shares held by the general public. Within
the five days prior to the commencement of the public offer, after taking into account the opinion of the audit committee, our Board of Directors must publish its opinion regarding the offer price.



Tender Offer Rules



Our bylaws provide that any purchasers or group of purchasers that obtain or increase a significant participation
(i.e., 30% or more) in the capital stock of the company, without conducting a previous public offer in accordance with the applicable rules issued by the CNBV, would not have the right to exercise the corporate rights of their shares, and
that the company will not register such shares in the share registry book.



Other Provisions



Variable
capital. We are permitted to issue shares constituting fixed and variable capital. All of our outstanding shares of capital stock constitute fixed capital. The issuance of variable-capital shares, unlike the issuance of fixed-capital shares,
does not require an amendment of the bylaws, although it does require a majority vote of the AA Shares and the A Shares. Under Mexican law and our bylaws, if we issued variable-capital shares, any holder of such shares would be entitled to redeem
them at the holders option at any time at a redemption price equal to the lower of:



| |  |  | 95% of the average market value of such shares on the Mexican Stock Exchange for 30 trading days preceding the date on which the exercise of the option is effective; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the book value of such shares at the end of the fiscal year in which the exercise of the option is effective.
| | - |  | -------------------------------------------------------------------------------------------------------------



83



---

##### Table of Contents

If the option is exercised during the first three quarters of a fiscal year, it is effective at the end of the next
succeeding fiscal year. The redemption price would be payable following the annual ordinary general meeting of holders of AA Shares and A Shares at which the relevant annual financial statements were approved.



Forfeiture of shares. As required by Mexican law, our bylaws
provide that any alien who at the time of incorporation or at any time thereafter acquires an interest or participation in the capital of the corporation shall be considered, by virtue thereof, as Mexican in respect thereof and shall be deemed
to have agreed not to invoke the protection of his own government, under penalty, in case of breach of such agreement, of forfeiture to the nation of such interest or participation. Under this provision, a non-Mexican shareholder is deemed to
have agreed not to invoke the protection of his own government by asking such government to interpose a diplomatic claim against the Mexican government with respect to the shareholders rights as a shareholder, but is not deemed to have waived
any other rights he may have, including any rights under the U.S. securities laws, with respect to his investment in Telmex. If the shareholder invokes such governmental protection in violation of this agreement, his shares could be forfeited to the
Mexican government. Mexican law requires that such a provision be included in the bylaws of all Mexican corporations unless such bylaws prohibit ownership of shares by non-Mexican persons.



Exclusive jurisdiction. Our bylaws provide that legal actions
relating to the execution, interpretation or performance of the bylaws shall be brought only in Mexican federal courts.



Duration. Telmexs existence under the bylaws is 100 years from the date of the public deed in which its incorporation is evidenced.



Purchase of our own shares. According to the
bylaws, we may repurchase our shares on the Mexican Stock Exchange at any time at the then prevailing market price. Any such repurchase must be made in compliance with the policies established by the Board of Directors, and the amount of shares to
be repurchased must be approved by the general ordinary shareholders meeting. The shareholders meeting approves the maximum amount of funds that may be used during the year for the repurchase of shares. The ordinary shareholders
meeting held on April 28, 2005 approved up to an additional P.6 billion to be used for share repurchases. Such funds may be used for the repurchase of shares through the Mexican Stock Exchange. In the event that we repurchase shares, our
shareholders equity will be reduced automatically in an amount equal to the assumed par value of each repurchased share. However, if repurchased shares are held as treasury stock, our capital stock will be reduced automatically in an amount
equal to the assumed par value of each repurchased share, pending future sales thereof on the Mexican Stock Exchange or cancellation. Our capital stock is automatically increased upon the resale of such shares in an amount equal to their assumed par
value. The economic and voting rights corresponding to repurchased shares may not be exercised during the period in which we own such shares, and such shares are not deemed to be outstanding for purposes of calculating any quorum or vote at any
shareholders meeting during such period.



Conflict
of interest. Shareholders with conflicting interests with Telmex with respect to a transaction are required to abstain from deliberating and voting on the specific transaction. A shareholder that votes on a specific business transaction in
which its interest conflicts with Telmexs may be liable for damages, but only if the transaction would not have been approved without its vote. A determination of conflicting interest would initially be made by the shareholder subject to
judicial challenge. Mexican law does not provide extensive guidance on the criteria to be applied in making such a decision.



84

##### Table of Contents

Appraisal rights. Whenever the shareholders approve a change of corporate purposes, change
of nationality of the corporation or transformation from one type of company to another, any shareholder entitled to vote on such change that has voted against it may withdraw from Telmex and receive the book value attributable to its shares,
provided it exercises its right within 15 days following the adjournment of the meeting at which the change was approved.



Rights of Shareholders



The protections afforded to minority shareholders under Mexican law are different from those in the United States and many other jurisdictions. The
substantive law concerning fiduciary duties of directors has not been the subject of extensive judicial interpretation in Mexico, unlike many states in the United States where duties of care and loyalty elaborated by judicial decisions help to shape
the rights of minority shareholders. Mexican civil procedure does not contemplate class actions or shareholder derivative actions, which permit shareholders in U.S. courts to bring actions on behalf of other shareholders or to enforce rights of the
corporation itself. Shareholders cannot challenge corporate action taken at a shareholders meeting unless they meet certain procedural requirements, as described above under Shareholders Meetings. As a result of these
factors, in practice it may be more difficult for our minority shareholders to enforce rights against us or our directors or controlling shareholders than it would be for shareholders of a U.S. company.



Enforceability of Civil Liabilities



Telmex is organized under the laws of Mexico, and most of our directors,
officers and controlling persons reside outside the United States. In addition, all or a substantial portion of our assets and their assets are located in Mexico. As a result, it may be difficult for investors to effect service of process within the
United States on such persons. It may also be difficult to enforce against them, either inside or outside the United States, judgments obtained against them in U.S. courts, or to enforce in U.S. courts judgments obtained against them in courts in
jurisdictions outside the United States, in any action based on civil liabilities under the U.S. federal securities laws. There is doubt as to the enforceability against such persons in Mexico, whether in original actions or in actions to enforce
judgments of U.S. courts, of liabilities based solely on the U.S. federal securities laws.



CERTAIN CONTRACTS



We are party
to concession agreements that authorize us to provide certain telecommunications services on specific terms. These are described in Item 4. Information on the CompanyMexican OperationsRegulation.



Our agreements with related parties are described in Item 7. Major
Shareholders and Related Party TransactionsRelated Party Transactions.



EXCHANGE CONTROLS



Mexico has had
a free market for foreign exchange since 1991, and the Mexican government has allowed the peso to float freely against the U.S. dollar since December 1994. There can be no assurance that the Mexican government will maintain its current foreign
exchange policies. SeeItem 3. Key InformationExchange Rates.

TAXATION



The following summary
contains a description of certain Mexican federal and U.S. federal income tax consequences of the acquisition, ownership and disposition of L Shares, A Shares, AA Shares, L Share ADSs, or A Share ADSs, but it does not purport to be a comprehensive
description of all of the tax considerations that may be relevant to a decision to purchase, hold or sell shares or ADSs.



The Convention for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion and a Protocol thereto between the United States and Mexico
entered into force on January 1, 1994 and has been amended recently by an additional protocol that entered into force on July 3, 2003 (the Tax Treaty). The United States and Mexico have also entered into an agreement concerning the
exchange of information with respect to tax matters.



This
discussion does not constitute, and should not be considered as, legal or tax advice to holders. The discussion is for general information purposes only and is based upon the federal tax laws of Mexico (including the Mexican Income Tax Law and the
Mexican Federal Tax Code) and the United States as in effect on the date of this Annual Report (including the Tax Treaty), which are subject to change, and such changes may have retroactive effect. Holders of shares or ADSs should consult their own
tax advisers as to the Mexican, U.S. or other tax consequences of the purchase, ownership and disposition of shares or ADSs, including, in particular, the effect of any foreign, state or local tax laws.



Mexican Tax Considerations



The following is a general summary of the principal consequences under the
Mexican Income Tax Law (Ley del Impuesto sobre la Renta) and the rules and regulations thereunder, as currently in effect, of an investment in shares or ADSs by a holder that is not a resident of Mexico and that will not hold the shares or
ADSs or a beneficial interest therein in connection with the conduct of a trade or business through a permanent establishment in Mexico (a nonresident holder).



For purposes of Mexican taxation, the definition of residency is highly technical and residency results in several
situations. Generally, an individual is a resident of Mexico if he or she has established his or her home in Mexico or if he or she has his or her center of interests in Mexico; a corporation is considered a resident if it is incorporated under the
laws of Mexico or if it has established its headquarters in Mexico. However, any determination of residence should take into account the particular situation of each person or legal entity.



Tax Treaties



Provisions of the Tax Treaty that may affect the taxation of certain U.S.
holders (as defined in U.S. Federal Income Tax Considerations) are summarized below.



The Mexican Income Tax Law has established procedural requirements for a nonresident holder disposing of his shares to be entitled to the benefits under
any of the tax treaties to which Mexico is a party. These procedural requirements include the obligation to (i) prove tax treaty residence, and (ii) appoint a representative in Mexico for taxation purposes.



Payment of Dividends



Dividends, either in cash or in kind, paid with respect to the of L Shares,
A Shares, AA Shares, L Share ADSs, or A Share ADSs will not be subject to Mexican withholding tax.

##### Table of Contents

Taxation of Dispositions



Under current Mexican law and regulations, there is no basis for the Mexican tax authorities to impose taxes on income
realized by a nonresident holder from a disposition of shares or ADSs, provided that (i) the transaction is carried out through (a) the Mexican Stock Exchange, (b) other securities exchanges or markets approved by the Mexican Ministry of Finance or
(c) other securities exchanges or markets with ample securities trading that are located in countries with which Mexico has entered into an income tax treaty, such as the New York Stock Exchange, the Frankfurt Stock Exchange, NASDAQ and the
Mercado de Valores Latinoamericanos en Euros (LATIBEX), and (ii) certain other requirements are met. In addition, income realized by a nonresident holder from tendering shares or ADSs pursuant to a public tender offer may be exempt from
Mexican taxation, provided that certain requirements are met. Sales or other dispositions of shares or ADSs carried out in other circumstances generally are subject to Mexican tax, except to the extent that a nonresident holder is eligible for
benefits under an income tax treaty to which Mexico is a party.



For non-resident corporations and individuals that do not meet the requirements mentioned above, gross income obtained on the sale or disposition of shares will be subject to 5% tax if the transaction is carried out through the Mexican
Stock Exchange or other securities markets approved by the Mexican Ministry of Finance. Under certain circumstances, non-resident corporations and individuals, alternatively, may elect to pay a 20% tax on the net amount of the transaction.



Pursuant to the Tax Treaty, gains realized by a U.S. holder
(as defined in U.S. Federal Income Tax Considerations) from the sale or other disposition of shares, even if the sale or disposition is not carried out under the circumstances described in the preceding paragraphs, will not be subject
to Mexican income tax, provided that such U.S. holder owned less than 25% of the shares representing our capital stock (including ADSs), directly or indirectly, during the 12-month period preceding such disposition.



Gains realized by other nonresident holders that are eligible to receive
benefits pursuant to other income tax treaties to which Mexico is a party may be exempt from Mexican income tax in whole or in part. Non-U.S. holders should consult their own tax advisers as to their possible eligibility under such treaties.



In other cases, nonresident holders will be subject to Mexican
income tax on the sale or other disposition of shares or ADSs. Such nonresident holders should consult with their own tax advisers as to how Mexican income tax would apply to their circumstances.



Other Mexican Taxes



Under certain circumstances, a nonresident holder will not be liable for
estate, inheritance or similar taxes with respect to its holdings of shares or ADSs. A gratuitous transfer of shares by a nonresident holder, however, may in certain circumstances result in the imposition of Mexican tax upon the recipient. There are
no Mexican stamp, issue registration or similar taxes payable by a nonresident holder with respect to shares or ADSs.



U.S. Federal Income Tax Considerations



The following is a summary of certain U.S. federal income tax consequences to U.S. holders (as defined below) of the acquisition, ownership and
disposition of shares or ADSs. The summary does not purport to be a comprehensive description of all of the tax consequences of the acquisition, ownership or disposition of shares or ADSs. The summary applies only to U.S. holders that will hold
their shares or ADSs as capital assets and does not apply to special classes of U.S. holders such as dealers in securities or currencies, holders with a functional currency other than the U.S. dollar, holders of 10% or more of our

##### Table of Contents

voting shares (whether held directly or through ADSs or both), tax-exempt organizations, financial institutions, holders
liable for the alternative minimum tax, securities traders electing to account for their investment in their shares or ADSs on a mark-to-market basis, and persons holding their shares or ADSs in a hedging transaction or as part of a straddle or
conversion transaction.



For purposes of this discussion, a
U.S. holder is a holder of shares or ADSs that is:



| |  |  | a citizen or resident of the United States of America;
| | - |  | ------------------------------------------------------



| |  |  | a corporation organized under the laws of the United States of America or any state thereof; or
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | otherwise subject to U.S. federal income taxation on a net income basis with respect to the shares or ADSs.
| | - |  | -----------------------------------------------------------------------------------------------------------



Each U.S. holder should consult such holders own tax advisor
concerning the overall tax consequences to it of the ownership or disposition of shares or ADSs that may arise under foreign, state and local laws.



Treatment of ADSs



In general, a U.S. holder of ADSs will be treated as the owner of the shares represented by those ADSs for U.S. federal income tax purposes. Deposits or
withdrawals of shares by U.S. holders in exchange for ADSs will not result in the realization of gain or loss for U.S. federal income tax purposes. U.S. holders that withdraw any shares should consult their own tax advisors regarding the treatment
of any foreign currency gain or loss on any pesos received in respect of such shares.



Taxation of Distributions



In this discussion, we use the term dividends to mean distributions paid out of our current or accumulated earnings and profits with respect to shares or ADSs. In general, the gross amount of any dividends
will be subject to U.S. federal income taxation. Dividends will be paid in pesos and will be includible in the income of a U.S. holder in a U.S. dollar amount calculated by reference to the exchange rate in effect on the day that they are received
by the U.S. holder in the case of shares or by the depositary in the case of ADSs. U.S. holders should consult their own tax advisors regarding the treatment of foreign currency gain or loss, if any, on any pesos received by a U.S. holder or
depositary that are converted into U.S. dollars on a date subsequent to receipt. Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by an individual prior to January 1, 2009 with respect
to the ADSs, L Shares and A Shares will be subject to taxation at a maximum rate of 15% if the dividends are qualified dividends. Dividends paid on the ADSs, L Shares and A Shares will be treated as qualified dividends if (i) we are
eligible for the benefits of a comprehensive income tax treaty with the Untied States that the Internal Revenue Service has approved for the purposes of the qualified dividend rules and (ii) we were not, in the year prior to the year in which the
dividend was paid, and are not, in the year in which the dividend is paid, (a) a passive foreign investment company, or PFIC, or (b) for dividends paid prior to the 2005 tax year, a foreign personal holding company, or FPHC, or foreign investment
company, or FIC. The Tax Treaty has been approved for the purposes of the qualified dividend rules. In addition, based on our audited financial statements and relevant market and shareholder data, we believe that we were not treated as a PFIC, FPHC
or FIC for U.S. federal income tax purposes with respect to our 2003 or 2004 taxable years. In addition, based on our audited financial statements and our current expectations regarding the value and nature of our assets, the sources and nature of
our income and relevant market and shareholder data, we do not anticipate becoming a PFIC for our 2005 taxable year.

The U.S. Treasury has announced its intention to promulgate rules pursuant to which holders of ADSs or
common stock and intermediaries through whom such securities are held will be permitted to rely on certifications from issuers to establish that dividends are treated as qualified dividends. Because such procedures have not yet been issued, it is
not clear whether we will be able to comply with them. Holders of ADSs and common shares should consult their own tax advisers regarding the availability of the reduced dividend tax rate in light of their own particular circumstances.



Dividends paid by us will not be eligible for the
dividends-received deduction allowed to corporations under the U.S. Internal Revenue Code of 1986, as amended (the Code).



Distributions of additional shares or ADSs to U.S. holders with respect to their shares or ADSs that are made as part of a pro rata distribution to all of
our shareholders generally will not be subject to U.S. federal income tax.



Taxation of Dispositions



A U.S. holder will recognize gain or loss on the sale or other disposition of the shares or ADSs in an amount equal to the difference between the U.S. holders basis in such shares or ADSs (in U.S. dollars) and the amount realized on
the disposition (in U.S. dollars, determined at the spot rate on the date of disposition if the amount realized is denominated in a foreign currency). Gain or loss realized by a U.S. holder on such sale or other disposition generally will be
long-term capital gain or loss if, at the time of disposition, the shares or ADSs have been held for more than one year. The net amount of long-term capital gain recognized by an individual holder is taxed at a reduced rate. Such gain or loss
generally will be treated as U.S. source gain or loss for U.S. foreign tax credit purposes.



Gain, if any, realized by a U.S. holder on the sale or other disposition of the shares or ADSs will be treated as U.S. source income for U.S. foreign tax credit purposes. Consequently if a Mexican withholding tax is
imposed on the sale or disposition of L Shares or A Shares, a U.S. holder that does not receive significant foreign source income from other sources may not be able to derive effective U.S. foreign tax credit benefits in respect of these Mexican
taxes. U.S. holders should consult their own tax advisors regarding the application of the foreign tax credit rules to their investment in, and disposition of, L Shares or A Shares.



Exchange of Shares



A U.S. holders exchange of A Shares for L Shares will not constitute a taxable event for U.S. federal income tax purposes. An exchanging U.S.
holder will have a tax basis in the L Shares equal to the basis such holder had in the exchanged A Shares. An exchanging U.S. holders holding period for the L Shares will include the holding period such U.S. holder had in the A Shares before
such shares were exchanged.



A U.S. holders exchange of L
Shares for AA Shares, pursuant to the option to exchange in respect of such L Shares, will not constitute a taxable event for U.S. federal income tax purposes. An exchanging U.S. holder will have a tax basis in the AA Shares received equal to the
basis such holder had in the exchanged L Shares. A U.S. holders holding period for AA Shares received in such an exchange will include the holding period such U.S. holder had in the L Shares prior to such exchange.



Information Reporting and Backup Withholding



Dividends on, and proceeds from the sale or other disposition of, the shares
or ADSs paid to a U.S. holder generally may be subject to the information reporting requirements of the Code and may be subject to backup withholding unless the holder:



| |  |  | establishes that it is a corporation or other exempt holder; or

| |  |  | provides an accurate taxpayer identification number on a properly completed Internal Revenue Service Form W-9 and certifies that no loss of exemption from backup withholding has
occurred.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The amount of any backup withholding from a payment to
a holder will be allowed as a credit against the U.S. holders U.S. federal income tax liability and may entitle such holder to a refund, provided that certain required information is furnished to the Service.



U.S. Tax Consequences for Non-U.S. holders



Distributions. A holder of shares or ADSs that is, with respect to
the United States, a foreign corporation or a non-resident alien individual (a non-U.S. holder) generally will not be subject to U.S. federal income or withholding tax on dividends received on shares or ADSs, unless such income is
effectively connected with the conduct by the holder of a U.S. trade or business.



Dispositions. A non-U.S. holder of shares or ADSs will not be subject to U.S. federal income or withholding tax on gain realized on the sale of shares or ADSs, unless:



| |  |  | such gain is effectively connected with the conduct by the holder of a U.S. trade or business; or
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | in the case of gain realized by an individual holder, the holder is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions
are met.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Information reporting and backup
withholding. Although non-U.S. holders generally are exempt from backup withholding, a non-U.S. holder may be required to comply with certification and identification procedures in order to establish its exemption from information reporting and
backup withholding.

Item 11. Quantitative and Qualitative Disclosures about Market Risk



EXCHANGE RATE AND INTEREST RATE RISKS



We are exposed to market risk from changes in currency exchange rates, changes in interest rates and changes in market prices of publicly traded securities.



Interest rate risk exists principally with respect to our indebtedness that bears interest at floating rates. We had
P.54,310 million of indebtedness bearing interest at floating rates at December 31, 2004. In 2002, we began entering into interest rate swaps under which we pay fixed-rate interest in pesos and receive floating-rate interest in pesos. In 2003, we
began entering into U.S. dollar-denominated interest rate swaps under which we pay fixed-rate interest in U.S. dollars and receive floating-rate interest in U.S. dollars. See Item 5. Operating and Financial Review and ProspectsHedging.



Exchange rate risk exists principally with respect to our
indebtedness denominated in currencies other than Mexican pesos. As of December 31, 2004, indebtedness denominated in foreign currencies was P.81,291 million, of which P.75,718 million was denominated in U.S. dollars, P.4,344 million was denominated
in Brazilian reais and P.1,229 million was denominated in other foreign currencies.



Market price risk exists principally with respect to our publicly-traded marketable securities. As of December 31, 2004, we had P.6,146 million in marketable securities, which we hold for trading purposes. Our
marketable securities are carried at market value, and gains and losses are recognized in our statement of income. We do not use any derivative instruments to hedge our marketable securities.



We regularly assess our exposure and monitor opportunities to manage these
risks, for example through the use of financial instruments. From time to time we use financial instruments to manage our market risk exposures. Since late 2001, we have entered into hedging transactions with respect to our U.S. dollar-denominated
indebtedness. We use these transactions, which may be foreign exchange forward exchange and option contracts, to hedge against changes in the exchange rate between the U.S. dollar and the Mexican peso. See Item 5. Operating and Financial Review
and ProspectsHedging.



SENSITIVITY ANALYSIS DISCLOSURES



Exchange
Rates



The potential loss in fair value of financial
instruments held at December 31, 2004 that would have resulted from a hypothetical, instantaneous and unfavorable 10% change in currency exchange rates would have been approximately P.6,300 million. Such a change in currency exchange rates would
also have resulted in additional interest expense of approximately P.293 million per year, assuming no change in the principal amount of such indebtedness, reflecting the increased costs in pesos of servicing foreign currency indebtedness. This
sensitivity analysis assumes an instantaneous unfavorable 10% change in exchange rates affecting the foreign currencies in which our indebtedness is denominated.



Interest Rates



The potential loss in fair market value of financial instruments held at December 31, 2004 that would have resulted from a hypothetical, instantaneous and
unfavorable change of 100 basis points in the interest rate applicable to such financial instruments would have been approximately P.784 million. This effect would be fully attributable to the impact of the interest rate change on fixed-rate
financial assets and liabilities. A hypothetical, instantaneous and unfavorable change of 100 basis points in the interest rate applicable to floating-rate financial assets and liabilities held at December 31, 2004 would have resulted in additional
interest expense of approximately P.378 million per year, assuming no change in the

##### Table of Contents

principal amount of such indebtedness. The above sensitivity analyses are based on the assumption of an unfavorable 100
basis point movement of the interest rates applicable to each homogeneous category of financial assets and liabilities. A homogeneous category is defined according to the currency in which financial assets and liabilities are denominated and assumes
the same interest rate movement with each homogeneous category. As a result, interest rate risk sensitivity analysis may overstate the impact of interest rate fluctuations for such financial instruments, as consistently unfavorable.



Market Prices



The potential loss in fair value of marketable securities held at December 31, 2004 that would have resulted from a
hypothetical, instantaneous and unfavorable 10% change in the market price of such securities would have been approximately P.615 million.

None.



Item 15. Controls and Procedures



We carried out an evaluation under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls
and procedures as of December 31, 2004. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and
procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our chief executive officer and chief financial officer concluded that
the disclosure controls and procedures as of December 31, 2004 were effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the Securities Exchange Act is recorded, processed,
summarized and reported as and when required.



There
has been no change in our internal control over financial reporting during 2004 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.



Item 16A. Audit Committee Financial Expert



Antonio del Valle Ruíz, the chairman of our audit committee and one of our alternate directors, has financial experience as required by the mandate of our audit committee. Our Board of Directors has established
that Mr. del Valle Ruíz is an audit committee financial expert. Mr. del Valle Ruíz, who studied accounting at the Escuela Bancaria y Comercial, acquired his expertise through his role as chief executive officer at various
Mexican banks over the last 35 years. Mr. del Valle Ruíz is independent, as audit committee member independence is defined in Rule 10A-3 under the U.S. Securities Exchange Act of 1934, as amended. See Item 6. Directors and Officers of
RegistrantAudit Committee.



Item 16B. Code of Ethics



We
have adopted a code of ethics, as defined in Item 16B of Form 20-F. Our code of ethics applies to all our personnel, including our chief executive officer, chief financial officer, principal accounting officer and persons performing similar
functions. Our code of ethics is available on our web site at www.telmex.com. If we amend the provisions of our code of ethics that apply to our chief executive officer, our chief financial officer, our principal accounting officer and persons
performing similar functions, or if we grant any waiver of such provisions, we will disclose such amendment or waiver on our web site at the same address.

the engagement of our independent auditors for services. Such policies and procedures outline services that require specific approval on a case-by-case basis and general services that have been approved in advance by the audit committee, which
include statutory and regulatory audits, tax compliance and evaluation of the security of our information technology. Prior to providing any services that require specific pre-approval, our independent auditor, together with our chief financial
officer, will jointly present to the audit committee a request for approval of audit services, in which such persons confirm that the request complies with applicable rules.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



To the Stockholders of

Teléfonos de México, S.A. de C.V.



We have audited the accompanying consolidated balance sheets of Teléfonos de México, S.A. de C.V. and subsidiaries as of December 31, 2004 and 2003, and the related consolidated statements of income,
changes in stockholders equity and changes in financial position for each of the three years in the period ended December 31, 2004. These financial statements are the responsibility of the Company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 Mexico and with the standards of the Public Company Accounting Oversight Board (United States of America). Such standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Companys internal control over financial reporting. Our audit included
consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Companys internal
control over financial reporting. Accordingly we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and
the significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.



In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated
financial position of Teléfonos de México, S.A. de C.V. and subsidiaries at December 31, 2004 and 2003, and the consolidated results of their operations, changes in their stockholders equity and changes in their financial
position for each of the three years in the period ended December 31, 2004, in conformity with accounting principles generally accepted in Mexico, which differ in certain respects from those followed in the United States of America (see Note 19).

I. Description of business



Teléfonos de México, S.A. de C.V. and its subsidiaries
(collectively the Company or TELMEX) provide telecommunications services, primarily in Mexico. However, as a result of a number of business acquisitions throughout Latin America, starting in 2004, the Company also provides
telecommunication services in Argentina, Brazil, Chile, Colombia and Peru.



TELMEX obtains its revenues primarily from telecommunications services, including, among others, domestic and international long-distance and local telephone services, data transmission to corporate networks and
Internet services, and the interconnection of the subscribers with cellular networks, as well as the interconnection of domestic long-distance operators, cellular telephone companies and local service operators networks with the
TELMEX local network. The Company also obtains revenues from other activities related to its telephone operations, such as the sale of advertising in the published telephone directory and the sale of telephone equipment.



An analysis of the principal subsidiaries and affiliated companies of TELMEX
at December 31, 2004 and 2003 is as follows:

TELÉFONOS DE MÉXICO, S.A. DE C.V. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2004 and 2003

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



The amended Mexican government concession under which the
Company operates was signed on August 10, 1990. The concession runs through the year 2026, but it may be renewed for an additional period of fifteen years. The concession defines, among other things, the quality standards for telephone service and
establishes the basis for regulating rates.



Under this
concession, the Companys basic telephone service rates are subject to a ceiling determined by the Federal Telecommunications Commission (COFETEL). During the last four years, TELMEX management decided not to raise its rates for basic services.



Empresa Brasileira de Telecomunicações S.A.
(Embratel) provides domestic and international long-distance services, which include voice, data transmission and other services, and Star One S.A. (Star One), a subsidiary of Embratel, provides satellite services. Both companies operate under two
separate concessions granted by the Brazilian federal government via the Brazilian Telecommunications Agency (Anatel). Both concessions expire on December 31, 2005. Embratels concession for domestic and international long-distance services may
be renewed for an additional twenty years and Star Ones concession for satellite use may be renewed for an additional fifteen years, subject to certain restrictions. In June 2003, Anatel announced the general terms and conditions under which
the licenses will be renewed. Both companies formally notified Anatel of their approval of such terms and conditions and expressed their intention to renew the concessions. The companies have not yet received renewals on the agreements, though
management is certain that such concessions will be renewed subject to certain rules.



The rest of the countries operate under concessions and government licenses.



II. Significant accounting policies



The accompanying consolidated financial statements were prepared in conformity with accounting principles generally accepted in Mexico. The significant accounting policies and practices followed in the preparation of
the financial statements are described below:



a) Consolidation and basis
of translation of financial statements of foreign subsidiaries



The consolidated financial statements include the accounts of Teléfonos de México, S.A. de C.V. and its subsidiaries (see Note 1.I). All the companies operate in the telecommunications sector or they provide services to
companies operating in this sector.



All significant
intercompany accounts and transactions have been eliminated in consolidation. Minority interest refers to certain foreign subsidiaries.



The financial statements of the subsidiaries located abroad were translated into Mexican pesos in conformity with Mexican Accounting Principles Bulletin
B-15, Transactions in Foreign Currency and Translation of Financial Statements of Foreign Operations, issued by the Mexican Institute of Public Accountants (MIPA), as follows:



The financial statements as reported by the subsidiaries abroad were adjusted to conform to accounting principles accepted
in Mexico. Such conversion includes, among other areas, the recognition of the effects of inflation as required by Mexican Accounting Principles Bulletin B-10, Accounting Recognition of the Effects of Inflation on Financial Information,issued by the MIPA, using restatement factors of each country.



All balance sheet amounts, except for stockholders equity, were translated at the prevailing exchange rate at year-end; stockholders equity accounts were translated at the prevailing exchange rate at the time capital
contributions were made and earnings were generated. The statement of income amounts were translated at the prevailing exchange rate at the end of the reporting period.

Years Ended December 31, 2004 and 2003

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



Translation differences are included in the caption
Effect of translation of foreign entities and are included in stockholders equity as part of the caption Other comprehensive income items.



b) Recognition of revenues



Revenues are recognized as they accrue and are subject to managements estimates at the date of the financial statements.



Local service revenues are derived from new-line installation charges,
monthly service fees, measured usage charges based on the number of calls made and other service charges to subscribers. Local service revenues also include measured usage charges based on the number of minutes in the case of prepayment
plans.



Revenues from domestic and international
long-distance telephone services are determined on the basis of the duration of the calls and the type of service used. All these services are billed monthly, based on the rates authorized by the relevant regulatory bodies of each country.
International long-distance service revenues also include the revenues earned under agreements with foreign telephone service providers or operators for the use of facilities in interconnecting international calls. These agreements specify the rates
for the use of such international interconnecting facilities. These service revenues represent the net settlement between the parties and include costs of P.1,212,960, P.1,677,282 and P.1,311,179 in 2004, 2003 and 2002, respectively.



Interconnection service revenues include charges for interconnecting
fixed-system users with cellular users, as well as the interconnection of domestic long-distance operators, cellular telephone companies and local service operators networks with the TELMEX local network.



Revenues from the sale of prepaid telephone service cards are recognized
based on an estimate of the usage of time covered by the prepaid card. Revenues from corporate networks are those related to data transmission services. In 2003, the Company began to defer its revenues from prepaid Internet plans. The effects of
this policy change represented a decrease in revenues of 2003 of approximately P. 185,000.



c) Recognition of the effects of inflation on financial information



The Company recognizes the effects of inflation on financial information as required by Bulletin B-10. Consequently, the amounts shown in the accompanying
financial statements and in these notes are expressed in thousands of constant Mexican pesos as of December 31, 2004. The December 31, 2004 restatement factors applied to the financial statements for the years ended December 31, 2003 and 2002 were
1.0519 and 1.0938, corresponding to the percentages of inflation for the periods from January 1 of 2004 and 2003 through December 31, 2004, respectively, based on the Mexican National Consumer Price Index (NCPI) published by Banco de México
(the Central Bank).



Plant, property and equipment and
construction in progress were restated as described in Note 4. Telephone plant and equipment are mainly depreciated using the straight-line method based on the estimated useful lives of the related assets (see Note 4 d).



Inventories for the operation of the telephone plant are valued at average
cost and are restated on the basis of specific indexes. The restated value of inventories is similar to replacement value, not in excess of market.



Other non-monetary assets were restated using adjustment factors obtained from the NCPI.



Capital stock, premium on sale of shares, and retained earnings were restated using adjustment factors obtained from the
NCPI.



Other accumulated comprehensive income items includes
the deficit from restatement of stockholders equity, which consists of the accumulated monetary position loss at the time the provisions of Bulletin B-10 were first applied, which was P. 13,591,715 and of the result from holding non-monetary
assets, which represents the net difference between restatement by the specific indexation method (see Note 4) and restatement based on the NCPI. This item is included in stockholders equity as part of the caption Other comprehensive income
items.

Years Ended December 31, 2004 and 2003

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



The net monetary gain of each year is included in the
statement of income as a part of the comprehensive financing cost. The net monetary gain represents the effect of inflation on monetary assets and liabilities. The net monetary gain of each year is included in the statements of income as a part of
the comprehensive financing cost.



Mexican Accounting
Principles Bulletin B-12, Statement of Changes in Financial Position, issued by the MIPA, specifies the appropriate presentation of the statement of changes in financial position based on financial statements restated in constant pesos.
Bulletin B-12 identifies the sources and applications of resources representing differences between beginning and ending financial statement balances in constant pesos. In accordance with this bulletin, monetary and foreign exchange gains and losses
are not treated as non-cash items in the determination of resources provided by operations.



d) Cash equivalents, marketable securities and instruments available for sale



Cash equivalents consist basically of time deposits in financial institutions with original maturities of 90 days or less.



Marketable securities are represented by equity securities and corporate
bonds for trading; instruments available for sale are represented by equity securities. Both are stated at market value. Changes in the fair value of instruments classified as available for sale are included in comprehensive income caption of
stockholders equity through the time they are sold (see paragraph t).



e) Hedging instruments



To protect itself
against fluctuations in interest and exchange rates, the Company uses derivatives including interest-rate swaps and short-term currency exchange hedges. The determined gains or losses on these transactions are credited or charged to income using the
accrual method, net of the gains or losses on the related liabilities covered, as required by Mexican Accounting Principles Bulletin C-2, Financial Instruments, issued by the MIPA (see Note 8).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2004 and 2003

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



f) Allowance for doubtful accounts



The Companys policy with respect to the allowance for doubtful
accounts is basically to provide for accounts receivable more than 90 days old.



g) Equity investments in affiliates



The
investment in shares of affiliates is valued using the equity method. This accounting method consists basically of recognizing the investors equity interest in the results of operations and in the stockholders equity of investees at the
time such results are determined (see Note 6).



h) Goodwill



Goodwill represents the excess purchase price paid for shares of acquired
companies over the fair value of the acquired net assets. Goodwill is being amortized using the straight-line method over periods of 5 to 20 years (see paragraph t).



i) Impairment of assets



Effective January 1, 2004, the Company adopted the requirements of Mexican Accounting Principles Bulletin C-15, Accounting for the Impairment or
Disposal of Long-lived Assets, issued in March 2003.



Such
Bulletin C-15 establishes that if there are any indications of impairment in the value of long-lived assets, the related loss should be determined based on the recovery value of the related assets, which is defined as the difference between the
assets fair value and its carrying amount. An impairment loss is recognized if the net carrying amount of the assets exceeds the recovery value.



The application of this new pronouncement had no effect on the Companys financial position or on its results of operations.



j) Exchange differences



Transactions in foreign currencies are recorded at the prevailing exchange rate at the time of the related transactions.
Foreign currency denominated assets and liabilities are translated at the prevailing exchange rate at the balance sheet date. Exchange rate differences are charged or credited to income of the year.



k) Labor obligations



Pension, seniority premiums and medical assistance costs are recognized periodically during the years of service of
personnel, based on actuarial computations made by independent actuaries, using the projected unit-credit method (see Note 7). Termination payments are charged to income in the year in which the decision to dismiss an employee is made.

l) Liability provisions



Mexican Accounting Principles Bulletin C-9, Liabilities, Provisions,
Contingent Assets and Liabilities and Commitments, went into effect on January 1, 2003. This Bulletin establishes the rules for valuing, presenting and disclosing both liabilities and provisions. This pronouncement also establishes the specific
rules for valuing and disclosing contingent assets and liabilities. It includes also the rules for disclosing commitments contracted by the Company in its day-to-day activities.



The initial accumulated effect of applying this accounting pronouncement and of creating the provision for vacations
represented a charge to retained earnings at the beginning of the 2003 of P. 748,489 (net of deferred taxes).



m) Income tax and employee profit sharing



The Company recognizes deferred taxes using the asset and liability method. Under this method, deferred taxes are recognized on virtually all temporary differences in balance sheet accounts for financial and tax
reporting purposes, using the enacted income tax rate at the date of the financial statements or the income tax rate that will be in force at the time the temporary differences giving rise to deferred tax assets and liabilities are expected to
reverse.



The Company evaluates periodically the possibility of
recovering deferred tax assets and, if necessary, creates a valuation allowance for those assets that are unlikely to be recovered.



Deferred employee profit sharing is provided on temporary non-recurring differences with a known turnaround time.



n) Comprehensive income



In conformity with Mexican Accounting Principles Bulletin B-4, Comprehensive Income, in the particular case of the
Company, comprehensive income consists of current year net income plus the effects of deferred taxes, labor obligations, the translation of financial statements of foreign entities, minority interest, the result from holding non-monetary assets and
changes in the value of instruments classified as available for sale applied directly to stockholders equity.



o) Earnings per share



The Company determined earnings per share by dividing majority net income by the weighted average number of shares issued and outstanding during the
period. The diluted earnings per share was determined by adjusting earnings per share for the effect of the shares that may be delivered (potentially dilutive shares) (see Note 15), as specified in Mexican Accounting Principles Bulletin B-14,
Earnings per share.

p) Use of estimates



The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions in certain areas. Actual results could differ from those estimates.



q) Concentration of risk



The Company invests a portion of its surplus cash in cash deposits in financial institutions with strong credit ratings. TELMEX does not believe it has
significant concentrations of credit risks in its accounts receivable because it has a broad and geographically diverse customer base.



r) Segment information



Segment information is prepared based on information used by the Company in its decision making processes based on the services provided and the
geographical areas in which TELMEX operates, in conformity with the requirements of Mexican Accounting Principles Bulletin B-5, Financial Information by Segment (see Note 18).



s) Financial instruments with characteristics of liabilities, equity or both



Requirements of Mexican Accounting Principles Bulletin C-12, Accounting
for Certain Financial Instruments with Characteristics of Liabilities, Equity or both, went into effect on January 1, 2004. The objective of Bulletin C-12 is to specify the differences between liabilities and equity. This Bulletin C-12 also
establishes the rules for classifying and valuing the initial recognition of the components of liabilities and equity of combined financial instruments, as well as the rules for disclosing information about such instruments. The application of this
new accounting pronouncement on the Companys convertible debt resulted in no change in the accounting treatment given to such instruments (see Note 8).



t) New accounting pronouncements



The new accounting pronouncements which go into effect in 2005 are as follows:



Business acquisitions



In May 2004, it was issued Mexican Accounting Principles Bulletin B-7,
Business Acquisitions. The observance of Bulletin B-7 is compulsory beginning on January 1, 2005, although earlier application is recommended. This Bulletin addresses the financial accounting and reporting for business and entity acquisitions
and requires that all business acquisitions be accounted for using the purchase method. It also eliminates the amortization of goodwill and provides specific rules related to the acquisition of minority interest and to the transfer of net assets
between entities under common control.



Management believes
that the adoption of this accounting pronouncement will give rise to a decrease in the Companys operating expenses for 2005 of approximately P. 200,000, derived from the non-amortization of goodwill.



Financial instruments



In April 2004, Bulletin C-2 was amended. The amendments change the rules for
valuing instruments classified as available-for-saleat their fair value and, unlike the previous Bulletin C-2, require the recognition of such instruments at fair value in stockholders equity, until such instruments are sold. The
amended Bulletin C-2 also provides the requirements and rules for the accounting treatment of transfers between financial asset categories. The amendments are also more precise in establishing the guidelines for the accounting treatment to be given
to impairment in the fair value of financial instruments. Furthermore, the amended bulletin requires that such instruments be classified as either short-term or long-term and clarifies the rules for presenting in the statement of changes in
financial position changes associated with the purchase, sale and maturity of financial instruments. Finally, the amendments broaden the disclosure rules established under Bulletin C-2.

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



The observance of this pronouncement is compulsory
beginning on January 1, 2005, although earlier observance is recommended. The Company adopted in 2004 the requirements of this new accounting rule, which gave rise to a charge to stockholders equity, as part of comprehensive income of P.
1,104,876.



Financial instruments derived from hedging activities



In April 2004, it was issued Mexican Accounting
Principles Bulletin C-10, Accounting for Derivative Instruments and Hedging Activities. The observance of this pronouncement is compulsory beginning on January 1, 2005, although earlier observance is recommended. Bulletin C-10 establishes the
defining characteristics that financial instruments must have to be considered derivatives, as well as the conditions that must be met for specifically designating derivatives as hedges. Bulletin C-10 also provides guidelines for assessing the
effectiveness of hedging derivatives and the rules for their valuation and the accounting for changes in their fair value. Management does not believe the adoption of this new accounting requirement will have a material effect on the Companys
financial position or on its results of operations.



Labor Obligations



In January 2004, the revised Mexican Accounting
Principles Bulletin D-3, Labor Obligations was issued. The revised bulletin establishes the overall rules for the valuation, presentation and disclosure of so-called other post-retirement benefits and the reduction and early
extinguishment of such benefits, thus nullifying the provisions of Circular 50 Interest Rates Applicable in the Valuation of Labor Obligations and Suppletory Application of Accounting Principles Related to Labor Obligations, issued by
the MIPA.Bulletin D-3 also provides rules applicable to Employeetermination payments. The observance of these new rules is compulsory beginning on January 1, 2005. Management does not believe the adoption of this new
accounting requirement will have a material effect on the Companys financial position or on its results of operations.



u) Convenience Translation



United States dollar amounts as of December 31, 2004 shown in the financial statements have been included solely for the convenience of the reader and are
translated from Mexican pesos with purchasing power as of December 31, 2004, as a matter of mathematical computation only, at an exchange rate of P. 11.2648 to U.S.$ 1.00, the December 31, 2004 exchange rate. Such translations should not be
construed as a representation that the Mexican peso amounts have been or could be converted into U.S. dollars at this or any other rate.



v) Reclassifications



Certain amounts shown in the 2003 financial statements as originally issued have been reclassified for uniformity of presentation with 2004.

b) Through December 31, 1996, items
comprising the telephone plant were restated based on the acquisition date and cost, applying the factors derived from the specific indexes determined by the Company and validated by an independent appraiser registered with the National Banking and
Securities Commission (CNBV).



Effective January 1, 1997,
Bulletin B-10 eliminated the use of appraisals to present plant, property and equipment in the financial statements. This caption was restated at December 31, 2004 and 2003 in each different country, as follows:



| |  | The December 31, 1996 appraised value of the imported telephone plant, as well as the cost of subsequent additions to such plant, were restated based on the rate of inflation in the
respective country of origin and the prevailing exchange rate at the balance sheet date (specific indexation factors).
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The appraised value of land, buildings and other fixed assets of domestic origin at December 31, 1996, and the cost of subsequent additions to such assets were restated based on the
NCPI.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



At December 31, 2004, approximately 61%
(57% in 2003) of the value of the plant, property and equipment has been restated using specific indexation factors.

d) Because of the progress and the
technological advances in telecommunications equipment, the Company makes a periodic assessment of the estimated useful lives of its fixed assets, adjusting annual depreciation whenever it believes this to be appropriate. In 2003, the Company
reduced the useful lives of certain assets, thereby increasing depreciation expense for 2003, as compared to 2002, by P. 886,228.



The following table shows the changes in useful lives that were made in 2003:



|                             |  |              |  |

|Management systems equipment |  | 11           |  | 5  



Depreciation of the
telephone plant has been calculated at annual rates ranging from 3.3% to 16.7%. The rest of the Companys assets are depreciated at rates ranging from 3.3% to 33.3%. Depreciation charged to costs and expenses was P. 22,602,381 in 2004, P.
21,561,390 in 2003 and P. 21,177,532 in 2002.

In May 1998, TELMEX
acquired from the Mexican government concessions to operate radio spectrum wave frequency bands to provide fixed wireless telephone services at a cost of P. 663,572. In December 1997, the Company also acquired from the Mexican government concessions
to operate radio spectrum wave frequency bands for point-to-point and point-to-multipoint microwave communications at a cost of P. 198,659. These costs are being amortized over a period of twenty years.

P. 43,112.



In 2004, as a result of the Companys
acquisition of foreign entities, TELMEX acquired software licenses and licenses for use of point-to-point and point-to-multi-point links, which are being amortized in periods from 5 to 29 years. Amortization expense for these licenses for 2004 was

6. Equity Investments



I. Investments in affiliated companies



a) An analysis of the equity investment in affiliated and other companies at December 31,
2004 and 2003, together with a brief description, is as follows:



|                             |  |      |         |      |    |

|Technology and Internet, LLC |  |      | 196,963 |      |    | 228,989
|Other                        |  |      | 210,682 |      |    | 197,942
|                             |  |      |         |      |    |        
|                             |  | P.   | 793,599 |      | P. | 876,634
|                             |  |      |         |      |    |        



In May 1999, the
Company entered into an agreement with WilTel Communications Group, Inc. (formerly known as Williams), to acquire approximately 1% of the shares comprising the capital stock of WilTel. In 2002 the Company decided to write off the balance of this
investment (P. 122,263), as TELMEX ceased to be a WilTels stockholder as a result of WilTels restructuring.



TELMEX holds 45% of the capital stock of Grupo Telvista, S.A. de C.V., whose principal asset is Telvista, Inc. that provides telemarketing services in the
United States of America (U.S.A.). In June 2004, the Company made a capital contribution to this company in the amount of P. 52,773 so as to maintain its historical percentage equity interest.



TELMEX holds 50% of the capital stock of Technology and Internet, LLC, which
has made investments in companies engaged in e-commerce, located basically in the U.S.A. and Latin America.



Total equity investments in affiliated companies during 2003 aggregated approximately U.S.$ 3 million (approximately U.S.$ 7 million in 2002), mostly
engaged in telecommunications companies. Goodwill generated on these investments was not material.



TELMEXs equity interest in the results of operations of affiliated companies represented a charge to operations of P. 114,856 in 2004 (charges of P.
187,965 in 2003 and P. 275,302 in 2002).



b) On January 16, 2002, TELMEX,
together with Forstmann Little & Co. (Forstmann Little), entered into a definitive agreement to make capital contributions of as much as U.S.$ 400 million each to XO Communications, Inc. (XO). The consummation of the agreement was dependent on,
among other things, XOs complete restructuring of its balance sheet and the approval of the transaction by the competent authorities.



On October 14, 2002, TELMEX and Forstmann Little mutually agreed with XO to terminate the investment commitment, each paying XO U.S.$ 12.5 million, thus
releasing all parties from any claim related to the commitment.

The Company determined the fair value of fixed assets by means of an
appraisal performed by independent experts based on the value in use of each asset.



Embrapar and Embratel (Brazil)



In July
2004, through an agreement between MCI and TELMEX, the Company acquired for U.S.$400 million all of MCIs direct and indirect holdings in Startel Participações Ltda and New Startel Participações Ltda, that were the
controlling shareholders of Embratel Participações S.A. (Embrapar), representing 51.8% of the voting shares and 19.3% of total outstanding shares of Embrapar. In December 2004 TELMEX, through a public offering of U.S.$ 271.6 million,
acquired an additional 14.3% interest in Embrapar, increasing its ownership to 90.3% of the voting shares and to 33.6% of the outstanding shares of Embrapar. Embrapar, in turn, holds 98.8% of the capital stock of Embratel.



In December 2004, the Board of Directors of Embrapar approved an
increase in the companys capital stock of approximately U.S.$ 700 million. Depending on market conditions at the time, TELMEX expects to

exercise its right to subscribe the Embrapar shares to which it is
entitled in accordance with Brazilian law in an amount ranging from U.S.$ 210 million to U.S.$ 700 million based on the amount subscribed by other investors. TELMEX is under no obligation to buy shares.



Subsequent event



On March 16 and April 8, 2005, TELMEX subscribed U.S.$231.5 million during the initial meeting to increase Embrapars
capital stock, increasing its ownership to 94.9% of the voting shares and 48.6% of the outstanding shares. In addition, TELMEX expects to exercise its right to subscribe the remaining unsubscribed shares in subsequent meetings that will take place
during the period from April 15 to May 3 of 2005; the outcome could increase its equity interest in Embrapar.



Chilesat (Chile)



In April 2004 TELMEX acquired in a private transaction a 40% interest in Chilesat Corp. S.A. (Chilesat) for U.S.$ 47 million. Chilesat provides telecommunications services primarily in Chile. Pursuant to a cash tender offer required by
Chilean law, in June 2004 TELMEX purchased for U.S.$ 67 million an additional 59.3% interest, increasing its ownership of Chilesat to 99.3%.



Techtel (Argentina)



In April 2004, TELMEX acquired an 80% equity interest in Techtel LMDS Comunicaciones Interactivas, S.A. and Telstar (Techtel), which provides
telecommunication services in Argentina and Uruguay. A 60% equity interest was acquired from América Móvil, S.A. de C.V. (América Móvil) for U.S.$ 75 million, and the remaining 20% equity interest was acquired from
Intelec, S.A. for U.S.$ 25 million. Since TELMEX and América Móvil are entities under common control, the excess of the cost over the book value was charged to retained earnings.



Metrored (Argentina)



In June 2004, TELMEX acquired most of the assets of Metrored, a company
engaged in providing telecommunications services in Argentina. The purchase price was U.S.$ 12 million.



AT&T Latin America Corp. assets (Argentina, Brazil, Chile, Colombia and Peru)



In February 2004, TELMEX acquired most of the assets of AT&T Latin America Corp. (AT&T), a company engaged in providing telecommunications
services to companies in Argentina, Brazil, Chile, Colombia and Peru. The purchase price was U.S.$ 196.3 million.



Net



TELMEX agreed with Globo Comunicações e Participações S.A., Distel Holding S.A. and Roma Participações Ltda.
(together, Globo), to acquire an equity interest in Net Serviços de Comunicações S.A. (Net), which is the largest cable television operator in Brazil. Net is currently engaged in restructuring its debt,
on which it ceased making payments in December 2002.



TELMEX
and Globo have agreed that, subject to the closing of Nets debt restructuring on specified terms and the satisfaction of other conditions, TELMEX will (a) purchase 49% of the voting interests and all the non-voting interests in GB
Empreendimentos e Participações S.A. (GB), a special-purpose company that will own 51% of the common shares of Net and (b) purchase additional common or non-voting preferred shares of Net from Globo. These transactions are
currently expected to close in March 2005. The total cost of these transactions will be between U.S.$ 250 million and U.S.$ 370 million. The Companys total direct and indirect equity interest in Net will be between 30% and 60%.

Subsequent event



On February 1, 2005, TELMEX purchased from Globo 7.3% of the voting shares
of Net for which it paid U.S.$ 20.3 million. On March 21, 2005, the Company completed the transactions, subject to the purchase agreement with Globo, investing U.S.$290.6 million, increasing TELMEXs equity interest to 36.6% of the voting
shares and 7.9% of the non-voting preferred shares, which represent 19.6% of the Net outstanding shares at the end of the increasing stockholders equity process, additionally to the indirect interest in common shares of Net, through GB. It was
also agreed with Globo that TELMEX would acquire all the shares that would be offered during the increasing stockholders equity process and that would be not subscribed by a third party, by a public offering of 0.35 reais per share.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2004 and 2003

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



At December 31, 2004 and 2003, the market value of the
trust fund for pensions and seniority premiums exceeded the accumulated benefit obligation by P. 8,650,825 and P. 3,691,498, respectively. In conformity with Bulletin D-3, the balance sheets show a net projected asset of P. 25,622,601 and P.
23,495,279 in 2004 and 2003, respectively.



In 2004, the net
actuarial gain of P. 1,690,227 was derived primarily from an actuarial gain of P.9,394,134, due to the favorable effect on plan assets of the overall behavior of the Mexican Stock Exchange and the increase in fixed-yield interest rates, as well as
an actuarial loss of P. 7,703,907, attributable to the increase in the projected benefit obligation due primarily to the fact that: (i) the number of employees that retired exceeded estimates made at the beginning of the year, (ii) that the Company
modified the estimated retirement age based on experience with retiring personnel (iii) and the Company updated the plans mortality rates.



In 2003, the net actuarial gain of P. 1,986,506 was derived primarily from an actuarial gain of P.5,461,511, due to the favorable effect on plan assets of
the overall behavior of the Mexican Stock Exchange, and an actuarial loss of P. 3,475,005 attributable to the increase in the projected benefit obligation due primarily to the fact that the number of employees who retired exceeded the estimated
number at the beginning of the year.



The rates used in the
actuarial studies as of December 31, 2004 and 2003 were as follows:

|                                |  |      |          



Pension amounts are
determined on the basis of compensations of employees in their final year of employment, their seniority, and their age at the time of retirement. The Company has established funds through Telos  Fundación Embratel de Seguridad Social,
an independent entity that manages the fund.



The transition
liability for the DPB is being amortized over a period of 20 years, which is the estimated remaining working lifetime of the Companys employees. Variances in assumptions are being amortized over a period of 19 years, which is the expected
remaining lifetime of the Companys retired personnel.

An analysis of the liability for the pension plan and
medical assistance plan at December 31, 2004 is as follows:



|                                                                                          |  |     |          |   |     |    |            |

|Net projected liability                                                                   |  | P.  | (195,038 | ) |     | P. | (790,714   | )
|                                                                                          |  |     |          |   |     |    |            |  



In 2004, the net
actuarial loss of P. 100,328 in the DBP and P. 118,233 in the MAP is due principally to the actuarial losses of P. 179,488 and P. 119,896, respectively, attributable to the adjustments for past experience and plan changes and actuarial gains of P.
79,160 and P. 1,663, respectively, due to the favorable effect on plan assets of the general behavior of fixed-yield instruments.



The rates used in the actuarial studies were as follows:



|                               |  |     
|------------------------------ |  | ----
|                               |  | %   
|Discount of labor obligations: |  |     
|Long-term average              |  | 11.3
|Increase in salaries:          |  |     
|Long-term average              |  | 5.0 
|Annual return on fund          |  | 11.3
|Annual inflation:              |  |     
|Long-term average              |  | 5.0 



At December 31, 2004,
77.8% of plan assets are represented by fixed-yield instruments, 13.9% by variable-yield instruments and the remaining 8.3% by other assets.



Defined contribution plan



The unfunded liability represents Embratels obligation for those participants that migrated from DBP to the DCP. Such liability is being amortized
over a period of 20 years starting on January 1, 1999. Any unpaid balance is adjusted monthly based on portfolio asset returns at that date subject to an increase based on the Brazilian consumer price index plus 6 percentage points for the year. At
December 31, 2004, the balance of the obligation of the DCP was P. 738,820.

and bears interest at the LIBOR plus 0.525%. The balance of these loans is included under Banks (U.S. dollar denominated liabilities).



Domestic senior notes



At December 31, 2004, TELMEX has placed domestic senior notes (Certificados Bursátiles) for a total of P. 7,450,000 under the P.
10,000,000 program authorized by the CNBV.



Lines of credit



At December 31, 2004, the Company has long-term lines
of credit with certain foreign finance institutions. The unused portion of committed lines of credit at December 31, 2004 totaled approximately P. 2,331,100, at a floating interest rate of approximately LIBOR plus 49 basis points at the time of use.
At December 31, 2004, Embratel has unused lines of credit in the amount of U.S.$ 143,515 that bear 3.5% interest at the time of use.



Prepaid debt



During 2004, TELMEX prepaid a portion of its debt with a number of financial institutions, excluding the repurchase of convertible bonds, in the amount of
approximately U.S.$ 948 million.



In December 2004, Embratel
concluded its prepayment of the debt included in its 2003 refinancing program. During the second half of 2004, Embratel prepaid approximately U.S.$ 558 million, thus settling loans bearing annual interest at the LIBOR plus 4% and the ICD (Interbank
certificate of deposit) plus 4%. Such loans were paid using proceeds from issuing commercial paper and from other financing obtained during the fourth quarter 2004. The purpose of repaying such loans was to reduce Embratels cost of financing
and release the guarantees provided under the debt refinancing program.

Hedges



As part of its currency hedging strategy, the Company (excluding Embratel)
uses derivatives to minimize the impact of exchange rate fluctuations on U.S. dollar denominated transactions. During 2004, the Company entered into short-term exchange rate hedges which, at December 31, 2004, hedged liabilities of U.S.$ 3,220
million (U.S.$ 585 million in 2003). In 2004, the Company recognized a charge of P. 499,679 (credit of P.826,886 in 2003 and P. 1,741,454 in 2002) to results of operations for these hedges corresponding to exchange differences.



To offset its exposure to financial risks, the Company entered into
interest-rate swaps. Under these contracts, the Company agreed to receive 182-day TIIE interbank rate and the treasury certificate (CETES) rate for contracts in Mexican pesos and to pay fixed rates on the amount determined by applying
agreed interest rates to the base amount. The effect of interest-rate swaps was recorded in results of operations.



At December 31, 2004, the Company had interest-rate swaps for a total base amount of P. 12,390 million. The Company had interest-rate swaps for a total
base amount of U.S.$ 1,050 million paying fixed rates and receiving a six-month LIBOR rate, and of U.S.$ 1,050 million under which it pays a six-month LIBOR rate and receives a fixed rate. At December 31, 2003, the Company had interest-rate swaps
for a total base amount of P. 12,390 million and U.S.$ 1,200 million. In the year ended December 31, 2004, the Company recognized a net expense for these swaps in comprehensive financing cost of P. 418,632 (P. 481,054 in 2003 and P. 318,563 in
2002). Additionally, in 2003 the Company replaced some of its Mexican peso-denominated hedges, recognizing a financing cost of P. 1,012,210.



The subsidiary Embratel also uses financial instruments with banks (swaps and forwards) to minimize the effects of exchange rate fluctuations on the
Brazilian real due to foreign currency denominated loans and interest. Such hedges cover the amounts of Brazilian real necessary to pay exchange rate fluctuations on foreign currency denominated liabilities. At December 31, 2004, the Company hedged
liabilities for U.S.$ 323.9 million. Under these contracts, Embratel recognized during the period from August through December 2004 a charge of P. 767,817 corresponding to exchange differences.

c) At December 31, 2004 the Company has outstanding letters of credit for approximately P.
122,436 (P. 167,000 in 2003), issued to foreign suppliers for purchase of materials and supplies.



Contingencies of Mexico



d) In February
1998, the Federal Commission of Economic Competition (COFECO) determined that Teléfonos de México, S.A. de C.V. has substantial power in what it referred to as five telecommunications markets so that, in conformity with Article 63 of
the Federal Telecommunications Act, COFETEL may impose specific obligations with respect to rates charged and quality of services and information.



The Companys external lawyers who are handling this matter are of the opinion that this finding is unjustified. Consequently, Teléfonos de
México, S.A. de C.V. filed an appeal in the Federal District Court and obtained protection and shelter under Mexican Federal law. In September 2004, COFECO handed down a new ruling supporting the findings with respect to the substantial power
that Teléfonos de México, S.A. de C.V. exercises over five telecommunications markets. Teléfonos de México, S.A. de C.V. filed an appeal in the Federal District Court. In October 2004, such appeal was admitted by the
court and the final ruling is still pending.



As a result, the
COFECO has initiated other proceedings against Teléfonos de México, S.A. de C.V. that have also being appealed.



e) In December 1995, a competitor that provides cellular telephone services reported Teléfonos de México, S.A. de C.V. to the COFECO for alleged
monopolistic practices and undue concentration.



In July 2001,
the COFECO ruled that Teléfonos de México, S.A. de C.V. was responsible for monopolistic practices and undue concentration. Teléfonos de México, S.A. de C.V. filed an appeal for reconsideration against the ruling, but the
appeal was declared unfounded and the ruling confirmed.

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



The respective defense against the confirmation of the
ruling has been presented before the Federal Court of Justice for Tax and Administrative Matters.



f) The Mexican Social Security Institute (IMSS) audited Teléfonos de México, S.A. de C.V. for the 1997-2001 period. At the conclusion of the audit, it was determined that Teléfonos de
México, S.A. de C.V. owed a total of approximately P. 330,000 (historical amount) in taxes, fines, surcharges and restatements at July 2, 2003. Teléfonos de México, S.A. de C.V. filed an appeal before the Federal Court of
Justice for Tax and Administrative Matters, and in accordance with Mexican laws, by means of a bank trust guaranteed payment of such tax liability through July 1, 2005. The Companys external lawyers who are handling this matter are of the
opinion that although the Companys appeal is well founded, there is no guarantee that it will prevail.



Contingencies of Embratel and Star One



Brazilian value-added goods and services tax (ICMS)



Embratel received a number of fines for non-payment of ICMS for services provided, including international services and others, considered by Embratel as exempted or non-taxable. Amounts of approximately P. 368,000
are considered as probable losses in the cases and were duly provided for in the subsidiarys financial statements. Amounts considered as corresponding to claims in which the lawyers consider Embratel will prevail are approximately P.
3,793,000; as a result, no provisions have been recorded for such amounts.



In July 2002, Star One received two assessments by the tax authorities in the state of Rio de Janeiro for payment of ICMS in the amount of approximately P. 1,001,000. These assessments refer to the ICMS tax on
Internet and satellite use. In March 2004, Star One was required to pay approximately P. 84,000 in the Brazilian Federal District for ICMS not paid on satellite use and other obligations. Based on managements and the lawyers estimates,
Star One faces low risk of losing these above-mentioned suits and consequently, has not provided for such amounts in its financial statements.



The Companys external lawyers who are handling this matter are of the opinion that although the Companys case is well founded, there is no
guarantee that it will prevail.



Income Tax on Inbound International
Income



Based on its legal advisors opinion,
Embratel believes that the foreign operating income from telecommunications services (inbound traffic) is not subject to taxation. In connection with this matter, in March 1999, the Brazilian Federal Tax Agency (SRF) assessed the subsidiary in the
amount of P. 1,219,000 approximately for failing to pay the related income tax for the years 1996 and 1997. Embratel appealed to the Taxpayers Council against this decision, which is still pending.



In June 1999, Embratel was further assessed for non-payment of income tax on
net foreign source income for 1998 amounting to approximately P. 273,000.



As a result of an unfavorable ruling of the administrative defense contesting this assessment, the Company requested a writ of mandamus, which was initially rejected by the court. However, such ruling was subsequently
modified so as to reflect a favorable decision for Embratel. Based on the opinion of the subsidiarys management and its legal advisors, who consider the probability of loss as unlikely, no provisions have been recorded for the related amounts
of the suits.



The Companys external lawyers who are
handling this matter are of the opinion that although the Companys case is well founded, there is no guarantee that it will prevail.

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



Brazilian Social Welfare Tax on Service Exports (PIS)



In August 2001, Embratel received a tax claim from
the Brazilian Federal Revenue Service (SRF) totaling approximately P. 675,000 for payment of the PIS prior to 1995, which had been offset in accordance with Brazilian tax law. Based on the facts and arguments provided, and also on the opinion of the
Companys external lawyers, Embratels management evaluated the probability of a loss and no provision was recorded in the financial statements for this matter. The Companys external lawyers who are handling this matter are of the
opinion that although the Companys case is well founded, there is no guarantee that it will prevail.



Brazilian Finance Tax for Service Export Security Tax (COFINS)



There is also a claim against Embratel amounting approximately of P. 1,451,000 related to the COFINS exemption on the exportation of telecommunication
services for revenues through the end of 1999. According to management, there were several errors in the computation of this tax made by the government auditor and, consequently, such amount was later reduced by approximately P. 934,000. Embratel
appealed the case in the highest administrative court and in July 2003, a ruling was issued requiring the claim to be returned to the first administrative level. A new decision was issued by the first administrative level confirming that the
remaining updated amount was approximately P. 1,004,000. Embratel appealed to a higher administrative level which is still pending decision.



Based on the facts and arguments provided, and also on the opinion of the Companys external lawyers, Embratels management considers the
probability of a loss in this case as unlikely. Accordingly, no provision was recorded in the financial statements for this matter.



The Companys external lawyers who are handling this matter are of the opinion that although the Companys case is well founded, there is no
guarantee that it will prevail.



Disputes with third parties



Certain cases are in an advanced stage of the
litigation process and, according to Embratels external lawyers, the subsidiary stands a chance of losing at least some of the cases; consequently, P. 700,060 (restated) has been provided for possible unfavorable rulings. For other litigation
totaling P. 62,809, Embratel provided guarantee deposits of P. 45,982. According to the Companys external lawyers, although the Companys arguments in this case are well-grounded, there is no guarantee of a favorable outcome.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2004 and 2003

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



During 2003, the Company acquired 668.3 million Series
L shares for P. 12,007,515 (historical cost of P. 11,197,226) and 3.9 million Series A shares for P. 70,720 (historical cost of P. 65,805).



During 2002, the Company acquired 387.3 million Series L shares for P. 6,774,662 (historical cost of P.
6,041,620) and 1.4 million Series A shares for P. 22,916 (historical cost of P. 20,747).



c) In conformity with the Mexican Corporations Act, at least 5% of net income of the year must be appropriated to increase the legal reserve. This practice must be continued each year until the legal reserve reaches
at least 20% of capital stock issued and outstanding.



d) In 2004, as a result
of the maturity of the convertible senior debentures, the Company issued 388.7 million Series L shares (see Note 8).



e) Earnings per share are obtained by dividing majority net income for the year by the average weighted number of shares issued and outstanding during the period. To
determine the average weighted number of shares issued and outstanding, the shares held by the Company have been excluded from the computation.



The diluted earnings per share were determined considering the effect of the shares that may be delivered (potentially dilutive shares) as a result of the
convertible senior debentures described in Note 8 and of the stock options described in Note 17. The computation was made by deducting from majority net income for the year, the comprehensive financing cost, net of income tax and employee profit
sharing, derived from the convertible debentures. The adjusted income was divided by the average weighted number of shares issued and outstanding, taking into account the number of potentially dilutive shares.



An analysis is as follows:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2004 and 2003

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



g) On March 9, 2005, the Company announced that on April 28, 2005 will
submit for consideration of the Extraordinary and the Annual Shareholders meeting, among other matters, a proposal to: (i) restructure the number of AA, A and L outstanding shares, through a two-for-one
stock split, and (ii) increase in P.6,000,000, in addition to the maximum authorized amount for the acquisition of own shares.



16. Income Tax, Asset Tax and Employee Profit Sharing



a) The Ministry of Finance and Public Credit authorized TELMEX to consolidate the Mexican companies group tax returns effective January 1, 1995. The Instituto
Tecnológico de Teléfonos de México, S.C. and the subsidiaries acquired during the year are excluded from this tax consolidation.



On November 1, 2004, the Ministry of Finance and Public Credit authorized the transmission of the tax consolidation of Teléfonos de México,
S.A. de C.V. and its Mexican subsidiaries to that of Carso Global Telecom, S.A. de C.V. (controlling company of TELMEX) starting in 2005 in conformity with the Mexican Income Tax Law. However, this does not result in the tax deconsolidation of
Teléfonos de México, S.A. de C.V. or its subsidiaries, nor in their ceasing to consolidate for tax purposes.



b) The 1.8% asset tax, which is a minimum income tax, is payable on the average value of most assets net of certain liabilities. Since asset tax may be credited against
income tax, the former is actually payable only to the extent that it exceeds income tax. Asset tax for the years ended December 31, 2004, 2003 and 2002 was P. 2,706,462, P. 3,004,233 and P. 2,944,063, respectively. In such years TELMEX credited
against these amounts the corporate income tax paid.



c) An analysis of income
tax provisions is as follows:

TELÉFONOS DE MÉXICO, S.A. DE C.V. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2004 and 2003

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



In 2003, the decrease in the effective tax rate for the
effect of financing costs derived basically from unrealized gains determined in the mark-to-market valuation of marketable securities.



On January 1, 2002, a gradual one-percentage point annual reduction in the corporate income tax rate was approved starting in 2003 until the rate reached
32% in 2005. The effect of this tax-rate change on deferred taxes represented a credit of P. 1,837,584 to 2002 results of operations.



The temporary differences on which the Company (excluding the new Latin American subsidiaries) recognized deferred taxes in the years ended December 31,
2004 and 2003, were as follows:

TELÉFONOS DE MÉXICO, S.A. DE C.V. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2004 and 2003

(In thousands of Mexican pesos with purchasing power at December 31, 2004)



Intersegmental transactions are reported at fair value.
Comprehensive financing cost and provisions for income tax and employee profit sharing are not assigned to the segments; they are handled at the corporate level.



Segment assets include plant property and equipment (on a gross basis) construction in progress, advances to suppliers of
equipment and inventories for operation of the telephone plant.



19.
Differences between Mexican and U.S. GAAP



The
Companys consolidated financial statements are prepared in accordance with Mexican GAAP, which differ in certain respects from accounting principles generally accepted in the United States (U.S. GAAP).



The reconciliation to U.S. GAAP does not include the reversal of the
adjustments to the financial statements for the effects of inflation required under Mexican GAAP (Bulletin B-10), because the application of Bulletin B-10 represents a comprehensive measure of the effects of price level changes in the Mexican
economy and, as such, is considered a more meaningful presentation than historical cost-based financial reporting for both Mexican and U.S. accounting purposes.



The principal differences between Mexican GAAP and U.S. GAAP, as they relate to the Company, are described below together with an explanation, where
appropriate, of the method used to determine the adjustments that affect operating income, net income, total stockholders equity and resources provided by operating and financing activities.



Cash flow information:



Under Mexican GAAP, the Company presents consolidated statements of changes
in financial position, as described in Note 1. The changes in the consolidated financial statement balances included in this statement constitute resources provided by and used in operating, financing and investing activities stated in constant
pesos (including monetary and foreign exchange gains and losses).



Statement of Financial Accounting Standards No. 95 (SFAS 95), Statement of cash flows, does not provide guidance with respect to inflation adjusted financial statements. In accordance with Mexican GAAP, the changes
in current and long-term debt due to restatement in constant pesos, including the effect of exchange differences, is presented in the statement of changes in financial position in the financing activities section. The company has adopted the
guidance issued by the AICPA SEC Regulations Committees International Practices Task Force in its meeting held on November 24, 1998, encouraging foreign registrants that file price level adjusted financial statements to provide cash flow
statements that show separately the effects of inflation on cash flows.

Cash flows from
purchases of trading securities during 2004 were P. 22,684 (P. 3,681,411 and P. 2,389,391 in 2003 and 2002, respectively) and cash flows from sales of trading securities during 2004 were P. 530,510 (P. 32,243 and P.285,849 in 2003 and 2002,
respectively).



Capitalized interest:



Under Mexican GAAP, the Company does not capitalize net financing costs on
assets under construction. Under U.S. GAAP, interest on borrowings in foreign currencies or comprehensive financing costs for borrowings in pesos, must be considered an additional cost of constructed assets to be capitalized in plant, property and
equipment and depreciated over the lives of the related assets. The amount of interest or net financing costs capitalized for U.S. GAAP purposes was determined by reference to the Companys average interest cost of outstanding borrowings.

Valuation of inventories and plant, property and
equipment:



As previously discussed in Note 4, through
December 31, 1996, items comprising the telephone plant were restated based on the acquisition date and cost, applying the factors derived from the specific indexes determined by the Company and validated by an independent appraiser registered with
the CNBV. Since January 1, 1997, the valuation method of plant, property and equipment was modified, as Bulletin B-10 eliminated the use of appraisals to restate inventories and plant, property and equipment.



The alternate restatement method allowed by the Bulletin B-10, which was the
one adopted in 1997 by the Company as described in Note 4, is not acceptable for U.S. GAAP purposes; consequently, the difference between this method and the restatement of inventories and plant, property and equipment based on the NCPI was taken to
the U.S. GAAP reconciliations subsequently presented.



As a
result of this comparison, inventories, plant, property and equipment and stockholders equity increased by P.4,239,874 (P.2,915,000 in 2003), and the depreciation expense for 2004 increased by P.2,247,562 (P.2,102,550 and P.2,508,678 in 2003
and 2002, respectively).



Accrued vacation pay:



Through December 31, 2002, consolidated financial
statements under Mexican GAAP recognized the expense for vacation pay when paid rather than during the vesting period. For U.S. GAAP purposes, the Company has determined the accrued liability for vacation pay at December 31, 2002, and accordingly,
has adjusted the expense for vacation pay during the period then ended. As stated in Note 1, beginning in January 1, 2003, Mexican GAAP require that vacation pay be recognized when earned, thus eliminating the difference between Mexican and U.S.
GAAP.



Deferred income tax and deferred employee profit
sharing:



Under Mexican GAAP, deferred income tax is
determined on virtually all temporary differences in balance sheets accounts for financial and tax reporting purposes, using the enacted income tax rate at the balance sheet date.



Statement of Financial Accounting Standards No. 109 (SFAS 109), Accounting for income taxes,
requires deferred income tax be determined using the liability method for all temporary differences between financial reporting and tax bases of assets and liabilities and that such difference be measured at the enacted income tax rates for the
years in which such taxes will be payable or refundable.



The
Company is required to pay employee profit sharing in accordance with Mexican labor law. Deferred employee profit sharing under U.S. GAAP has been determined following the guidelines of SFAS No.109. Under Mexican GAAP, the deferred portion of
employee profit sharing is determined on temporary non-recurring differences with a known turnaround time.



The deferred tax adjustment included in the net income and stockholders equity reconciliations, also includes the effect of deferred taxes on the
other U.S. GAAP adjustments reflected in the respective summaries.



The differences in the recognition of deferred income tax and deferred employee profit sharing (for purposes of this note, collectively deferred taxes) between Mexican and U.S. GAAP for purposes of the income statement were as
follows:



|     |  |    |           |  
|---- |  | -- | --------- | -
|2002 |  | P. | (451,106  | )

The effect of income tax and employee profit sharing on
the difference between the indexed cost and the specific indexation factor valuation of fixed assets and inventories, primarily for operation of the telephone plant, and additionally on the minimum pension and seniority premium liability adjustment,
is applied as an adjustment to stockholders equity. The related accumulated amounts at December 31, 2004 and 2003 that decreased equity were P. (1,249,395) and P. (1,192,201), respectively.



The yearly changes in the accumulated amount for deferred taxes applied to
equity as a result of this effect from 2002 through 2004 are the following:



|     |  |    |           |  
|---- |  | -- | --------- | -
|2002 |  | P. | 5,604,864 |  
|2003 |  | P. | 242,029   |  
|2004 |  | P. | (57,194   | )



In 2004, monetary gain
of P. 45,958 and in 2003 and 2002 monetary losses of P.74,673 and P. 176,744, respectively, on the deferred taxes balance related to the difference between the indexed cost and replacement cost valuation of fixed assets and inventories, primarily
for operation of the telephone plant, and additionally on the minimum pension and seniority premium liability adjustment, were taken to equity, as part of the change of the year.



Significant components of deferred taxes under U.S. GAAP at December 31, 2004 and 2003 are as follows:

The investment
policies of plan assets are the following:



| |  |  | Tax rules issued by the Ministry of Finance and Public Credit:
| | - |  | --------------------------------------------------------------



Asset investments of the pension fund must be made through an irrevocable trust set up with a financial credit institution authorized to operate in
Mexico.



To invest at least 30% of assets in Mexican
government securities registered in the National Registry of Securities and Intermediaries (Registro Nacional de Valores e Intermediarios) or in shares of investment funds in debt instruments (sociedades de inversión).



The remaining 70% (maximum) will be invested in securities
approved by the CNBV.



Beginning on January 1, 2007, the fund
will not be allowed to invest more than 10% of total assets in Companys own shares or in shares of related companies.



| |  |  | Trading:
| | - |  | --------



The fund invests in securities approved by CNBV with high trading, liquidity and credit quality.



| |  |  | Plan assets structure:
| | - |  | ----------------------



Ensure that the composition of assets comprising the pension fund generates sufficient resources and liquidity to cover growth of pension obligations.



The Companys policy that defines long-term interest
rates to discount the obligations of the pension plan is based on the historical returns of real short term interest rates for the last 20 years in Mexico. Before 1984, debt securities yielded negative interest rates in real terms and for that
reason the Company decided not to go beyond twenty years of historical interest rates, with the purpose to adopt the current Mexican monetary policy. As part of the policys criteria, interest rates used in the projection are those available at
the end of the last year.



The historical averages of real
interest rates for the last twenty years ended in December 31, 2001 and 2002 have increased (from 6.45% in 2000 through 6.58% in 2001, and through 7.83% in 2002) as a result of the government monetary policy of giving an increased real premium. In
2001 and 2002, interest rates worldwide have been lower and for that reason, the Company decided not to modify discount real interest rates used in actuarial projections for 2002 and 2003.

The unrecognized net transition obligation under SFAS No.
87 of P. 6,351,490 at January 1, 1997, is being amortized over the average future working lifetime of the employee group, which has been determined to be 12 years. The portion of the unrecognized net (loss) gain that exceeds 10% of the greater of
projected benefit obligation or plan asset, will also be recognized over 12 years.



In 1995, consistent with the deferral of the unrecognized net (loss) gain, TELMEX included in income of such year an amount of P. 742,782 as monetary gain on the unfunded liability and deferred P.3,910,691, which
represented the difference between the amount credited to income and the full monetary gain on the unfunded liability. For 1996, the Company did not defer the monetary gain for such year, as the rates used in the actuarial study were similar to
actual inflation for 1996, and amortized P. 204,748 of the monetary gain deferred in 1995. The monetary gain deferred in 1995 is being amortized in 12 years. In 2004, 2003 and 2002, the Company amortized P. 336,907 each year, on the monetary gain
deferred in 1995. At December 31, 2004, the balance pending of amortization was P. 1,010,716 (P. 1,347,623 in 2003).

|(*) | The unfunded liability of P. 655,369 as of January 1, 2004 represented the amount due by the plan sponsor for the participants that migrated from the defined benefit plan to the
defined contribution plan. This liability is being amortized over a period of 20 years from January 1, 1999 (according to a specific cash flow schedule). Any unpaid balance is adjusted monthly based on the return on the portfolio assets at that
time, subject to a minimum increase based on the General Price Index (IGP-DI) plus 6% p.a.

Concentrations of
Risk



Certain financial instruments potentially subject
the Company to concentrations of credit risk. These financial instruments consist primarily of trade receivables and temporary cash investments. The Company places its temporary cash investments with high credit quality financial institutions and,
by policy, limits the amount of credit exposure to any financial institution.



Approximately 30% of Embratels employees are affiliated with state and/or municipal labor unions (Sindicato dosTrabalhadores das Empresas de Telecomunicação, known as Sinttel), which
is associated with the Federação Nacional dos Trabalhadores em Empresas de Telecomunicações e Operadores de Mesas Telefônicas, known as Fenattel, or with the Federação Interestadual dos
Trabalhadores em Empresas de Telecomunicações, known as Fittel, with which labor agreements are negotiated. Approximately 0.3%, 18% and 1.4% of the employees of BrasilCenter, Star One and Vésper, respectively, are associated
with labor unions.

Labor agreements are negotiated for BrasilCenter employees
with the state labor unions of each of the five different states where BrasilCenter operates, and for Star One employees with the labor union of the state of Rio de Janeiro. Labor agreements are negotiated for Vésper employees with the labor
unions of the state of Rio de Janeiro and São Paulo. Embratels relationship with its employees and their union are generally good. Embratel has not experienced a work stoppage that has had a material effect on our operations for many
years. The labor agreements with all of our employees have two-year term, except the labor agreement with BrasilCenter employees in the cities of Ribeirão Preto, Juíz de Fora and Rio de Janeiro. For the labor agreements with two-year
term, some economic issues (e.g., salaries and benefits) pertaining to the labor agreements are subject to revision after 12 months. Currently, the labor agreements for employees of BrasilCenter, Embratel and Vésper are effective.



There is no concentration of available sources of labor, services,
concessions or rights, other than those mentioned above, that could, if suddenly eliminated, severely impact the Company operations.



Effects of inflation accounting on U.S. GAAP adjustments:



To determine the net effect on the consolidated financial statements of recognizing the adjustments described above, it is necessary to recognize the
effects of applying the Mexican GAAP inflation accounting provisions (described in Note 1) to such adjustments. These effects are taken into consideration in the preparation of U.S. GAAP reconciliations of net income, operating income and equity.



Disclosure about fair value of financial instruments:



In accordance with Statement of Financial Accounting
Standards No. 107 (SFAS 107), Disclosures about fair value of financial instruments, under U.S. GAAP it is necessary to provide information about the fair value of certain financial instruments for which it is practicable to
estimate that value. The carrying amounts of cash and short-term investments, accounts receivable and accounts payable and accrued liabilities approximate fair values due to the short maturity of these instruments.



The fair value of total debt, excluding capital leases, is estimated using
discounted cash flow analyses based on current borrowing rates offered to the Company for debt of the same remaining maturities and the market value for the convertible senior debentures and senior notes at December 31, 2004 and 2003. As of December
31, 2004, the carrying value of total debt is P. 88,572,414 (P. 70,079,624 at December 31, 2003) and the fair value is P. 90,060,874 (P. 73,525,361 at December 31, 2003).



Business combinations and goodwill and other intangible assets:



In June 2001, the Financial Accounting Standards Board (FASB) issued
Statements of Financial Accounting Standards No. 141, (SFAS 141), Business combinations, and No. 142 (SFAS 142), Goodwill and other intangible assets, effective for fiscal years beginning after
December 15, 2001. Under the new rules, goodwill and intangible assets deemed to have indefinite lives will no longer be amortized but will be subject to annual impairment tests in accordance with the Statements. Other intangible assets will
continue to be amortized over their useful lives. The application of this pronouncement did not have any effect on the Companys financial position or on its results of operations.



Reporting comprehensive income:



Cumulative effects of the deficit from restatement of stockholders equity, deferred taxes on the difference between
indexed cost and replacement cost, effect of available for sale securities and effect of translation of foreign entities, as adjusted for U.S. GAAP purposes, included in comprehensive income at December 31, 2004, decreased (increased)
stockholders equity by P. 39,902,814, P. 2,071,791, P.1,104,876 and P. (769,322), respectively.

For U.S. GAAP
reporting, beginning January 1, 2001, the Company adopted Statement of Financial Accounting Standards No. 133, (SFAS 133), Accounting for derivative instruments and hedging activities, as amended, which establishes that all
derivative instruments (including certain derivative instruments embedded in other contracts) should be recognized in the balance sheet as assets or liabilities at their fair values and changes in their fair value are recognized immediately in
earnings, unless the derivative qualifies as a hedge as defined in SFAS 133 for which certain special accounting treatment is permitted.



The principal difference between SFAS 133 and Bulletin C-2 affecting the company relates to the requirements to apply for hedge accounting. SFAS 133
provides very specific requirements to qualify for hedge accounting at inception and during the term of the hedging relationship. Under Bulletin C-2, hedge accounting is permitted when the Company has the intent to hedge and the derivative
instrument has similar risk characteristics to the underlying asset or liability being hedged.



As of December 31, 2004 and 2003, the differences in accounting for derivative instruments between Mexican and U.S. GAAP, as they relate to the Company, resulted in certain adjustments in the reconciliation of net
income and the reconciliation of stockholders equity to U.S. GAAP, which are explained as follows:



| |  | Under Bulletin C-2, interest rate swaps negotiated with the intention of hedging interest rate risk on the Companys indebtedness should be accounted consistently with the
underlying hedged item. Mexican GAAP does not permit the recognition of hedge debt instruments at fair value. Accordingly, the estimated fair value of the derivative instrument qualifying as a hedge of an underlying debt instrument is not recognized
in the balance sheet and the effects in the income statement are recognized as interest on the debt accrues. Under SFAS 133, the interest swaps did not qualify as a hedge; therefore, the fair value must be recorded in the balance sheet and the
changes in fair value recognized directly to earnings.

| |  | As of December 31, 2004 and 2003, the estimated fair value of those interest rate swaps that were not recognized in the balance sheet under Mexican GAAP were asset of P. 593,139 and
P. 193,565, respectively, the effects in earnings have been reflected as a gain (loss) of P. 409,408 in 2004, P. 461,911 in 2003, and (P. 279,026) in 2002 in the reconciliation of net income to U.S. GAAP.

Stock options:



Under Mexican GAAP, TELMEX records no compensation expense with respect to
these stock options. Under U.S. GAAP the Company recognizes a compensation expense using the intrinsic value-based method of accounting prescribed by APB Opinion No. 25, Accounting for stock issued to employees, as allowed by Statement
of Financial Accounting Standards No. 123 (SFAS 123), Accounting for stock based compensation. Under the intrinsic value method compensation expense is recognized as the differences between the quoted market price at the date
of grant and the exercise price paid by the employee. If no payment is required the expense is based on the quoted market price of the Companys shares on the date of grant.

For purposes of these
pro forma disclosures, the estimated fair value of the options granted is amortized to expense over the options vesting period. The fair value for these options was estimated at the date of grant, using a Black-Scholes option pricing model
with the following assumptions used for grants in 2004 and 2003: risk-free interest rate of 9.68% and 9.48%; dividend yield of 3.84% and 3.61%; expected volatility factor of 18.5% and 27.0%; and expected option life of 1.0% and 3.2 years,
respectively. The fair value of the options at the date of grant in 2004 and 2003 was P. 6.42 and P. 8.19, respectively.



Impairment or disposal of long-lived assets:



In August 2001, the FASB issued Statement of Financial Accounting Standards No. 144 (SFAS 144), Accounting for the impairment or
disposal of long-lived assets, which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and supersedes Statement of Financial Accounting Standards No. 121 (SFAS 121), Accounting
for the impairment of long-lived assets and for long-lived assets to be disposed of, and the accounting and reporting provisions of APB Opinion No. 30, Reporting the results of operations for a disposal of a segment of a business.
SFAS 144 is effective for fiscal years beginning after December 15, 2001, with earlier application encouraged. The Company adopted Statement 144 as of January 1, 2002 and the adoption of this Statement did not have an impact on the U.S. GAAP
financial position and results of operations.

Accounting for certain financial instruments with
characteristics of both liabilities and equity:



In May
2003, the FASB issued Statement of Financial Accounting Standards No. 150 (SFAS 150), Accounting for certain financial instruments with characteristics of both liabilities and equity. The Statement establishes standards for
how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. The adoption of SFAS 150 did not have an impact on the U.S. GAAP financial information.



Consolidation of variable interest entities:



In January 2003, the FASB issued Interpretation No. 46, Consolidation
of variable interest entities, as amended. Interpretation No. 46 addresses how to identify variable interest entities and provides guidance as to how a company may assess its interests in a variable interest entity for purposes of deciding
whether consolidation of that entity is required. The adoption of Interpretation No. 46 did not have an impact on the U.S. GAAP financial information.



Statement of exchanges of non-monetary assets:



On December 12, 2004 The FASB issued SFAS No. 153 Statement of exchanges of non-monetary assets, an amendment of APB Opinion No. 29. This
Statement is the result of a broader effort by the FASB to improve the comparability of cross-border financial reporting by working with the International Accounting Standards Board (IASB) toward development of a single set of high-quality
accounting standards. This Statement amends Opinion 29 to eliminate the exception for non-monetary exchanges of similar productive assets and replaces it with a general exception for exchanges of non-monetary assets that do not have commercial
substance. A non-monetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. It becomes effective for financial statements for fiscal periods beginning after
June 15, 2005. The Company believes that the adoption this FASB will not have impact on its financial position, results of operations or cash flows.
