4th Quarter 2011

· At December 31, 2011, TELMEX supported 14.814 million lines, a decrease of 5.0% compared with the same period of the previous year. The lines included:

· Countries around the world are experiencing a continuing decrease in penetration of fixed lines. In a market of approximately 19.3 million fixed lines, TELMEX has a market share of 76.9% if public telephony, Telmex Social and prepaid lines that are mainly in rural areas are included. This market share is below the average of 85.7% for the 35 most representative countries ( Bank of America Merrill Lynch, Global Wireline Matrix 2011 ).

· Regarding our high speed Internet access service infinitum , we continue promoting and, thanks to our customer’s preference, we expanded from 67,000 accesses and a market share of 28.8% in December 2002 ( Bank of America Merrill Lynch, Global Wireline Matrix 2011 ) to 8.0 million broadband accesses and a market share of more than two thirds of Internet access services nationwide at the end of December 2011. In this period, broadband Internet accesses in Mexico increased an average of 57.5% in placing the country with the highest growth rates (OECD- Broadband portal) among the OECD country members. In this manner, infinitum is consolidated as the best connection due to its quality, service, price and high speed with by offering speed of 3 Mbps for 149 pesos (taxes included), placing infinitum with one of the most competitive prices in the world.

· infinitum’ s growth has been supported by t he sale of 3.2 million c omputers since 1999. This growth has been affected by some of the main broadband barriers, the lack of PC penetration in Mexican homes and low income per capita in a considerable part of the population .

· In 2012, for the twelfth consecutive year, TELMEX will continue reducing the price of our services to suppo r t Mexican families and enterprises. With this commitment, TELMEX passes to our customers the benefits of high efficiency and productivity that the company has worked to achieve in recent years.

· Across TELMEX, we continue to evolve our telecommunications platform. We are making investments to keep us at the forefront of technological development with the most reliable, efficient and secure state-of-the-art technology network available in the market, in order to offer int e grated products and services, at attractive prices and with world-class quality.

· TELMEX drives education and digital culture in the country and has benefited more than 2.8 million students, teachers and parents in cooperation with institutions and the governments of all 32 Mexican states. Among important results to highlight are 3,500 Casas, Aulas , (TELMEX Computer Halls) and Bibliotecas Digitales TELMEX (TELMEX Digital Libraries) where training in information technologies is provided, Also, Inttelmex IT provides post-graduate studies in IT, with the purpose of training specialists to lead technological change in public institutions and private companies.

Additionally, we launched the technological platform “ AcadémicaInnovación Tecnológica para la Educación Superior (Technological Innovation for Higher Education), which has entered into more than 170 agreements with higher-education institutions and has several digitized historical academic resources.

· Revenues in the fourth quarter totaled 29.143 billion pesos, an increase of 4.2 % compared with the same period of 2010, mainly due to an increase of 26.0% in data revenues, which include revenues from information technology projects that offset the 6.9% decrease from voice services.

· From October to December, adjusted EBITDA (1) totaled 11.348 billion pesos, producing a margin of 38.9%. Operating income totaled 6.934 billion pesos, with a margin of 23.8%.

Relevant Events

Tender Offer for TELMEX’s Shares

On December 19, 2011, TELMEX’s Extraordinary Shareholders Meeting approved to delist and/or cancel its American Depositary Shares (“ADSs”) from the New York Stock Exchange (NYSE), from the NASDAQ Capital Market (NASDAQ), from the Mercado de Valores Latinoamericanos en Euros in Madrid, Spain (Latibex) and from other foreign markets, as well as to terminate its American Depositary Receipt “ADR” program.

Recently, TELMEX filed Form 25 in the NYSE and NASDAQ which will soon end trading of TELMEX’s shares in those markets. On January 31, 2012 TELMEX ended trading its shares in the Mercado de Valores Latinoamericanos en Euros in Madrid, Spain (Latibex).

It is important to highlight that TELMEX shares will continue to be traded on the Bolsa Mexicana de Valores (Mexican Stock Exchange).TELMEX and América Móvil have not yet determined whether or when they will seek to delist the shares from the Mexican Stock Exchange.


Operating Results

Lines and local traffic

At December 31, 2011, TELMEX supported 14.814 million lines, a decrease of 5.0% compared with the same period of the previous year. The lines included:

Telmex Social: 1.496 million lines concentrated in rural communities and prepaid lines, with a reduction of 465,000 prepaid lines in the last 12 months .

Also, 689,000 public telephony lines, which have decreased in the last 12 months by 63,000.

During the fourth quarter, local calls decreased 8.9% compared with the same period of 2010, totaling 4.258 billion. The decline reflected the lower nu mb er of billed lines due to the growth in cellular telephony services and competition from other operators, as well as customers’ changing consumption profiles.


Long distance

In the fourth quarter, domestic long distance (DLD) traffic decreased 2.1% compared with the same quarter of 2010, totaling 4.350 billion minutes, mainly due to, among other factors, the decrease in termination traffic with other cellular telephony operators and less traffic because of the decrease of billed lines.

In the quarter, outgoing international long distance (ILD) traffic increased 3.3% compared with the fourth quarter of 2010, totaling 381 million minutes. Among other factors contributing to this increase was higher termination traffic from cellular operators. Incoming international long distance traffic rose 29.3% compared with the fourth quarter of 2010, totaling 2.604 billion minutes. The incoming-outgoing ratio was 6.8 times .


Interconnection

In the fourth quarter, interconnection traffic totaled 10.816 billion minutes, 2.5% higher than the same quarter of 2010, due to the 9.8% increase in interconnection traffic with long distance and cellular operators, partially offset by the 3.7% decrease in traffic related to calling party pays services.


Internet access

Regarding our high speed Internet access service infinitum, we continue promoting and, thanks to our customer’s preference, we expanded from 67,000 accesses and a market share of 28.8% in December 2002 (Bank of America Merrill Lynch, Global Wireline Matrix 2011) to 8.0 million broadband accesses and a market share of more than two thirds of Internet access services nationwide at the end of December 2011. In this period, broadband Internet accesses in Mexico increased an average of 57.5% in placing the country with the highest growth rates (OECD- Broadband portal) among the OECD country members. In this manner, infinitum is consolidated as the best connection due to its quality, service, price and high speed with by offering speed of 3 Mbps for 149 pesos (taxes included), placing infinitum with one of the most competitive prices in the world.

infinitum’ s growth has been supported by the sale of 3.2 million compute rs since 1999. This growth has been affected by some of the main broadband barriers, the lack of PC penetration in Mexican homes and low income per capita in a considerable part of the population.


Financial Results

The following financial information for 2011 and 2010 is presented in nominal pesos, according to International Financial Reporting Standards (IFRS).

Revenues: In the fourth quarter, revenues totaled 29.143 billion pesos, an increase of 4.2% compared with the same period of the previous year. Revenues related to data services, information technologies and other revenues from Tiendas TELMEX (TELMEX Stores) increased 26.0% and 16.8%, respectively. Revenues related to voice services decreased 6.9% compared with the previous year’s fourth quarter.


Adjusted EBITDA (1) and o perating income : Adjusted EBITDA (1) totaled 11.348 billion pesos in the fourth quarter of 2011, an increase of 2.9% compared with the same period of the prior year. The adjusted EBITDA margin was 38.9%. Operating income totaled 6.934 billion pesos in the fourth quarter and the operating margin was 23.8%.

Financing cost: In the fourth quarter, financing cost produced a charge of 1.066 billion pesos. This was a result of: i) a net interest charge of 928 million pesos, 11.5% higher than the same quarter of last year, related to recognition of the market value of interest rate swaps, partially offset by debt reduction, and ii) a net exchange loss of 138 million pesos because of the fourth-quarter exchange rate depreciation of 0.557 pesos per dollar and the 2.101 billion dollars in dollar-peso hedges in effect at December 31, 2011.

Net income: In the fourth quarter, net income attributable to controlling interest was 4.085 billion pesos, 21.3% higher than the same period of the previous year. Earnings per share were 22.6 Mexican cents, 22.2% higher than the fourth quarter of 2010, and earnings per ADR (2) were 33.0 US cents, an increase of 10.7% compared with the same period of the previous year.

Investments: In the fourth quarter of 2011 , capital expenditures (Capex) were the equivalent of 588 million dollars, of which 76.1% was used for growth and infrastructure projects in the data business, connectivity and transmission networks.

Debt: Total debt at December 31, 2011, was the equivalent of 5.136 billion dollars, 895 million dollars less than in 2010. Of this total, 82.3% is long-term, 52.2% has fixed rates taking interest rate swaps into consideration, and 50.1% is in foreign currency, equivalent to 2.573 billion dollars. To minimize risks from variations in the exchange rate, at December 31, 2011, we had dollar-peso hedges for 2.101 billion dollars.

Total net debt (3) was equivalent to 5.008 billion dollars at year-end 2011, a decrease of 417 million dollars compared with year-end 2010.

1. Description of the Business and Significant Events

I. Description of the Business


Teléfonos de México, S.A.B. de C.V. and its subsidiaries (collectively “the Company” or “TELMEX”) provide telecommunications services, primarily in Mexico, including domestic and international long distance and local telephone services, data services, the connection of customers with cellular networks (calling party pays), as well as the interconnection of domestic long distance carriers’ cellular telephone companies’ and local service carriers’ networks with the TELMEX local network. TELMEX also obtains revenues from the sale of telephone equipment and personal computers.


The amended Mexican government concession under which TELMEX 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. Among other significant aspects, the concession stipulates the requirements for providing telephony services and establishes the basis for regulating prices.


The prices to be charged for basic telephone services are subject to a cap determined by the Federal Telecommunications Commission (COFETEL). During the last eleven years, TELMEX management decided not to raise its prices for basic services.


TELMEX has concessions in Mexico to operate radio spectrum wave frequency bands to provide fixed wireless telephone services and to operate radio spectrum wave frequency bands for point-to-point and point-to-multipoint microwave communications.


The foreign subsidiary has licenses for use of point-to-point and point-to-multipoint links in the U.S.A.


The Corporate offices of the Company are located at Parque Vía 190, Colonia Cuauhtémoc, C.P. 06599, Mexico City, Mexico and its corporate website is www.telmex.com.


On April 17, 2012, TELMEX’s Audit Committee and management authorized the issuance of these consolidated financial statements and related notes. These consolidated financial statements will be approved by the Company’s shareholders at their next meetings, as provided by Mexican Law; the Company’s shareholders have the authority to modify the financial statements.


II. Significant Events


a) Public Exchange Offers


On May 11, 2010, América Móvil, S.A.B. de C.V. (América Móvil) launched two concurrent public exchange offers to acquire the outstanding shares of Carso Global Telecom, S.A.B. de C.V. (Carso Global Telecom), which was TELMEX’s controlling shareholder, and Telmex Internacional, S.A.B de C.V.. Carso Global Telecom was the direct holder of 59.4% of the outstanding shares of TELMEX. On June 16, 2010, América Móvil completed the acquisition of 99.4% of the outstanding shares of Carso Global Telecom, by means of a first public exchange offer. As a result, América Móvil indirectly owned 59.1% of the outstanding shares of TELMEX. Upon completion of this transaction, TELMEX became a subsidiary of América Móvil.


On October 11, 2011, América Móvil launched a public tender offer to acquire the outstanding shares of TELMEX, of which it was not already the direct or indirect holder. On November 11, 2011, América Móvil concluded the public tender offer to acquire the shares, and as a result of that offer, its direct and indirect ownership of the outstanding shares of TELMEX increased to 92.99%.


b) On December 19, 2011, at the Extraordinary General Meeting, the shareholders approved to proceed to delist and/ or cancel the registry or inscription of TELMEX´s shares or American Depositary Shares (“ADSs”), from the New York Stock Exchange (“NYSE”) and the NASDAQ Capital Market (“NASDAQ”) and its L Shares from the Mercado de Valores Latinoamericano en Euros in Madrid, Spain (“Latibex”), and to terminate its American Depositary Receipt (“ADRs”) programs. On January 31, 2012, TELMEX filed Form 25 with the U.S. Securities and Exchange Commission, after which TELMEX’s ADSs ended trading on the NYSE and NASDAQ. On the same date, TELMEX ended trading its L shares on Latibex. However, TELMEX shares will continue to be traded on the Bolsa Mexicana de Valores (Mexican Stock Exchange). On April 3, 2012, TELMEX called for an Extraordinary Shareholders’ Meeting to be held on April 25, 2012, to discuss the approval, as applicable, of the deregistration of the Company’s securities from the National Securities Registry (Registro Nacional de Valores) and the delisting from the Mexican Stock Exchange.


2. Adoption of International Financial Reporting Standards (IFRS)


The Company, with the respective authorization of its Board of Directors, Audit Committee, the Mexican Stock Exchange and the Mexican National Banking and Securities Commission, decided to adopt IFRS as issued by the International Accounting Standards Board (“IASB”) as of December 31, 2011, using a transition date as of January 1, 2010. As a result, the accompanying financial statements and the notes thereto have been prepared in accordance with IFRS.


The Company’s 2010 annual financial statements were prepared in conformity with Mexican Financial Reporting Standards (Mexican FRS). Mexican FRS differ in some aspects with IFRS. In the following paragraphs the effects of IFRS adoption on the financial statements previously issued under Mexican FRS are explained. Also, the reconciliations of the statements of financial position as of January 1, 2010 and December 31, 2010, as well as, the reconciliation of the statement of income for the year ended December 2010, which were previously prepared under Mexican FRS and modified in accordance with IFRS since the transition date, are included.


The financial statement transition has been carried out with the application of IFRS 1 “First time adoption of International Financial Reporting Standards”. This standard provides mandatory exceptions which prohibit the retroactive adoption of IFRS in some areas, particularly those in which retroactive adoption requires management professional judgment on past conditions after the transactions endings were already known.


The Company is a consolidated subsidiary of América Móvil. América Móvil adopted IFRS on December 31, 2010, with a transition date to IFRS of January 1, 2009. The Company is carrying forward in these financial statements, the IFRS adoption amounts of its assets and liabilities which were included in its América Móvil’s consolidated statement of financial position at their date of transition to IFRS, as permitted under IFRS 1.


TELMEX is applying the mandatory exceptions established in IFRS 1 for the retroactive application of other standards as of the transition date. Those IFRS are related to the following concepts:


1. Determination of estimates

2. Derecognition of financial assets and liabilities

3. Hedge accounting

4. Non-controlling interest

5. Classification and measurements of financial assets


IFRS 1 also establishes optional exemptions to not retrospectively apply IFRS, in specific areas where the costs of complying with this requirement may exceed the benefits to be gained by users of the financial statements.


The Company is applying the following optional exemptions:


a) Deemed cost


In accordance with IFRS 1, an entity may elect to measure an item of property, plant and equipment at the date of transition to IFRS at its fair value and use that fair value as its deemed cost at that date.

A first-time adopter may elect to use a previous GAAP revaluation of an item of property, plant and equipment at, or before, the date of transition to IFRS as deemed cost at the date of the revaluation, if the revaluation was, at the date of the revaluation, broadly comparable to:

(a) Fair value; or

(b) Cost or depreciated cost in accordance with IFRS, adjusted to reflect, for example, changes in a general or specific price index.


TELMEX decided to use the revalued cost of property, plant and equipment at January 1, 2009, determined in accordance with Mexican FRS, which includes the inflation effects through December 31, 2007, as their deemed cost for purposes of its América Móvil’s consolidated statement of financial position. Those deemed cost values, along with 2009 acquisitions, disposals and depreciation have been carried forward as the carrying value of property, plant and equipment at TELMEX’s January 1, 2010 transition date to IFRS.


b) Employee benefits


Cumulative actuarial losses


According to IAS 19, “Employee Benefits”, an entity may elect to use a corridor approach that leaves some actuarial gains and losses unrecognized. Retrospective application of this approach requires an entity to split the cumulative actuarial gains and losses from the inception of the plan until the date of transition to IFRS into a recognized portion and an unrecognized portion.


However, a first-time adopter may elect to recognize all cumulative actuarial gains and losses at the date of transition to IFRS, even if it uses the corridor approach for later actuarial gains and losses.

TELMEX decided to apply retrospectively the “corridor approach”, therefore, the recognition of the actuarial losses and gains has been deferred. The decrease in the net projected asset of P.1,216,055 at the transition date relates to the differences in the valuation of employee benefits between Mexican FRS and IFRS for the use of nominal rates for IFRS purposes instead of real rates as required for Mexican FRS purposes until December31, 2007.


Deferred employee profit sharing


Mexican FRS D-3, “Employee Benefits”, requires the recognition of deferred employee profit sharing in the financial statements. IFRS do not provide specific guidelines for recognizing deferred employee profit sharing, therefore, the liability for deferred employee profit sharing of P. 3,954,136, was not recognized for IFRS purposes at the transition date.


Termination benefits


Mexican FRS D-3 requires the recognition of an actuarial provision for the termination benefits of the employment relationship for other reasons than a restructuring, while IFRS does not consider this situation. Accordingly, TELMEX reversed the liability of P.159,377 for termination benefits at the transition date.


c) Recognition of the effects of inflation on financial information


IAS 29 “Financial Reporting in Hyperinflationary Economies” requires the recognition of the inflation effects in the financial information when the entity operates in a hyperinflationary economic environment; one of the characteristics of a hyperinflationary economic environment is when the cumulative inflation rate in the prior three years is equal to or exceeds 100%.


The last three-year period in which Mexico ceased to be a hyperinflationary economic was in the period from 1996 to 1998. Therefore, the Company eliminated the effects of inflation from its non-monetary assets and liabilities, as well as from capital stock and legal reserve, recognized under Mexican FRS from January 1, 1999 through December 31, 2007.


d) Cumulative effects of translation of foreign entities


In accordance with IFRS1, a first-time adopter need not comply with IAS 21, “The Effects of Changes in Foreign Exchange Rates”. TELMEX applied this exemption. Therefore, the cumulative translation effect from foreign entities determined in conformity with Mexican FRS was deemed to be zero at the date of transition. Such amount recorded under Mexican FRS was P.134,550, net of deferred tax, at that date.


e) Credit risk of the Company and counterparty


IAS 39, “Financial Instruments: Recognition and Measurement”, requires the consideration of credit risk in determining the fair value of financial instruments. Credit risk is the risk that the counterparty will not meet its contractual obligations. For the transition to IFRS, TELMEX adjusted the fair value of the asset and liability position of the derivative financial instruments considering the credit risk of the counterparty.


Therefore, the fair value of the asset and liability position of the derivative financial instruments is presented net of the adjustment of the credit risk valuation, which includes both TELMEX’s own risk and the risk that comes from counterparties to the derivative financial instruments contracted. The credit risk amount at the date of transition was P.137,027.


f) Deferred taxes


As a result of the exceptions applied as well as the differences previously described, there were modifications in the accounting values of certain assets and liabilities. As a consequence, the deferred taxes were recalculated in accordance with IAS 12, “Income Taxes”, resulting in an increase of P.661,039 in the deferred tax liability at the IFRS transition date.


g) Statement of cash flows


The transition from Mexican FRS to IFRS did not have a material impact on the statement of cash flows.


h) Other


The transition from Mexican FRS to IFRS did not have a material impact on the other comprehensive income items.

3. Significant Accounting Policies and Practices


The principal accounting policies and practices followed by the Company in the preparation of these consolidated financial statements, in conformity with IFRS, are described below:


a) Basis of preparation


The accompanying financial statements have been prepared in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board (IASB) (hereafter referred to as IFRS), in force at December 31, 2011, and are the first consolidated financial statements prepared by the Company under IFRS.

The preparation of these financial statements under IFRS requires the use of critical estimates and assumptions that affect the amounts reported for certain assets and liabilities, as well as certain income and expenses. It also requires that management exercise judgment in the application of the Company’s accounting policies.


The Mexican peso is the functional currency and reporting currency of these financial statements.


The consolidated financial statements as of December 31, 2010, which were previously prepared in accordance with the Mexican FRS, have been modified in accordance with IFRS since the transition date.


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


i) Consolidation and equity method


The consolidated financial statements include the accounts of Teléfonos de México, S.A.B. de C.V and those of the subsidiaries over which the Company exercises control. All of the companies operate in the telecommunications field or provide services to companies relating to this activity.


Subsidiaries are fully consolidated from the acquisition date, which is the date when TELMEX obtains control, and continue to be consolidated until the date when TELMEX no longer has such control. The financial statements of the subsidiaries are prepared for the same reporting period as TELMEX, using consistent accounting policies.


All intercompany balances and transactions have been eliminated in the consolidated financial statements.


Non-controlling interest refers to certain subsidiaries in which the Company does not hold 100% of the shares. Non-controlling interest is presented as a separate caption of equity in the consolidated statements of financial position, and in the consolidated statements of income and statements of comprehensive income.


The investments in associated companies in which the Company exercises significant influence are accounted for using the equity method, whereby TELMEX recognizes its share in the net income and equity of the associates (Note 8).


The results of operations of the subsidiaries and associates were incorporated in the Company’s consolidated financial statements as of the month following their acquisition.


TELMEX’s equity interest in its principal subsidiaries and associated companies is as follows:

ii) Basis of translation of financial statements of foreign subsidiaries


The financial statements of foreign subsidiaries are consolidated after they are converted to IFRS in the functional currency, and then converted to the reporting currency. The assets and liabilities in the financial statements of subsidiaries were translated to Mexican pesos at the prevailing exchange rate at the end of the year, equity accounts were translated at the prevailing exchange rate at the time capital contributions were made and earnings were generated. Revenues, costs and expenses were translated at the historical exchange rate. Translation differences are recorded in equity in the caption “Effect of translation of foreign entities”, under “Accumulated other comprehensive income items”.


c) Revenue recognition


Revenues are recognized at the time services are rendered. Local service revenues are related to 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 for prepayment plans, based on the number of minutes.


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 the sale of equipment are recorded when the product is delivered to the customer


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, which are billed monthly based on the authorized prices. International long distance and interconnection service revenues also include the revenues earned under agreements with foreign carriers for the use of the Company’s facilities in interconnecting international calls. These services are regulated by agreements with these operators, in which the prices to be paid are defined.


Data revenues include revenues from services related to data transmission through private and managed networks and revenues from Internet access.


d) Use of estimates


The preparation of financial statements in conformity with IFRS requires the use of estimates and assumptions in certain areas. Actual results could differ from these estimates. TELMEX based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising beyond the control of TELMEX. Such changes are reflected in the estimates and assumptions and the related effect in the financial statements when they occur.


These estimates refere principally to the following:



e) Financial assets and liabilities


Financial assets and liabilities within the scope of IAS 39 generally include investments in financial instruments, debt and equity instruments, accounts receivable and other accounts receivable, loans and financing, accounts payable and accrued liabilities and derivative financial instruments.


Financial assets and liabilities are initially recognized at fair value, plus directly attributable transactions costs, except for those designated upon initial recognition at fair value through profit or loss.


The subsequent measurement of financial assets and liabilities depends on how they are classified as either financial assets and liabilities measured at fair value, financial assets and liabilities held to maturity and available for sale, loans and accounts receivable.


The financial assets of TELMEX include cash and cash equivalents, trade accounts receivable and other accounts receivable, listed and unlisted financial instruments and derivative financial instruments.


Financial liabilities are classified into the following categories based on the nature of the financial instruments contracted or issued: financial liabilities measured at fair value and financial liabilities measured at their amortized cost.



The Company’s financial liabilities include accounts payable to suppliers, deferred revenues, other accounts payable, loans and derivative financial instruments. Derivative financial instruments are recognized at fair value and short-and long-term debt, as well as accounts payable, are accounted for as financial liabilities measured at their amortized cost.


Offsetting of financial instruments


Financial assets and financial liabilities are offset and the net amount is presented in the consolidated statement of financial position if, and only if (i) there is currently a legally enforceable right to compensate the recognized amounts, and (ii) there is the intention to either settle them on a net basis, or to realize the assets and settle the liabilities simultaneously.


Financial instruments fair value


At each financial statement reporting date, the fair value of financial instruments traded in active markets is determined based on market prices, or prices quoted by financial intermediaries (purchase price for asset positions and sales price for liability positions), without any deduction for transaction costs.


For financial instruments that are not traded in an active market, the fair value is determined using generally accepted valuation techniques. Such techniques may include using recent arm’s length market transactions, references to the current fair value of another financial instrument that is substantially similar, a discounted cash flow analysis or other valuation models.


Fair values are determined based on the following hierarchy:


Level 1. Quoted prices (unadjusted) in active markets for identical assets or liabilities;


Level 2. Variables other than quoted prices in Level 1 that are observable for the asset or liability, either directly (prices) or indirectly (derived from prices) and;


Level 3. Variables used for the asset or liability that are not based on any observable market data (non-observable variables).


Note 13 provide an analysis of the fair values of the Company’s financial instruments.


f) Cash and cash equivalents


Cash at banks earn interest at floating rates based on daily bank deposit rates. Cash equivalents are represented by short-term deposits made for varying periods of between one day and three months, depending on the immediate cash requirements of the Company, and earn interest at the respective short-term deposit rates. Such investments are stated at acquisition cost plus accrued interest, which is similar to their market value.


g) Allowance for doubtful accounts


The allowance for doubtful accounts is determined based on the Company’s historical experience, past due balances and economics trends, as well as the evaluation of accounts receivable in litigation seeking recovery. The allowance for doubtful accounts primarily covers the balances of accounts receivable greater than 90 days old.


The risk of uncollectibilitty from related parties receivables is evaluated annually based on an examination of each related party’s financial situation and the markets in which they operate.


h) Derivative financial instruments and hedging activities.


The Company is exposed to interest rate and foreign currency risks, which are mitigated through a controlled risk management program that includes the use of derivative financial instruments. The Company uses primarily cross-currency swaps and when necessary foreign currency forwards to offset the short-term risk of exchange rate fluctuations. In order to reduce the risks due to fluctuations in interest rates, the Company utilizes interest-rate swaps, through which it either pays or receives the difference between the net cash amount resulting from paying or receiving a fixed interest rate, and from receiving or paying a variable interest rate, on notional amounts denominated in Mexican pesos or U.S. dollars. Most of these derivative financial instruments qualify and have been designated as cash flow hedges.


The Company’s policy includes: (i) formal documentation of all hedging relationships between the hedging instruments and the hedged positions; (ii) the objectives of risk management, and (iii) the strategy for conducting hedging transactions. This process takes into account the relationship between the cash flows of the derivatives with the cash flows of the corresponding Company’s assets and liabilities recognized in the statement of financial position.


The effectiveness of the Company’s derivatives used for hedging purposes is evaluated prior to their designation as hedges, as well as during the hedging period, which is performed at least quarterly based on recognized statistical techniques. Whenever it is determined that a derivative is not highly effective as a hedge or that the derivative ceases to be a highly effective hedge, the Company ceases to apply hedge accounting for the derivative on a prospective basis. For the years ended December 31, 2011 and 2010, there were no gains or losses recognized due to changes in the accounting treatment of hedges.


Derivative financial instruments are recognized in the statement of financial position at their fair values, which are obtained from the financial institutions with which the Company has entered into the related agreements. The Company’s policy is to verify such fair values against valuations provided by an independent valuation agent contracted by the Company. The effective portion of the cash flow hedge’s gain or loss is in equity under the caption “Accumulated other comprehensive income items”, while the ineffective portion is recognized in current year earnings. Changes in the fair value of derivatives that do not qualify as hedging instruments are recognized immediately in earnings.


The change in fair value recognized in earnings related to derivatives that are accounted for as hedges is presented in the same income statement caption as the gain or loss on valuation of the primary position.


i) Inventories


Inventories are valued using the average cost method. The balance of inventories presented in the statement of financial position does not exceed their net realizable value.


The net realizable value is the estimated selling price in the ordinary course of business less the estimated costs necessary to make the sale.


The estimate of the net realizable value of inventories is determined based on their age and turnover.


j) Property, plant and equipment


Property, plant and equipment at the transition date to IFRS are recorded as discussed above. Property, plant and equipment acquired after the transition date are recorded at acquisition cost. Amounts are recorded net of accumulated depreciation less any impairment losses. The acquisition cost includes, in addition to the purchase price, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.


Depreciation is computed using the straight line method, based on the estimated useful lives of the related assets, beginning the month after they become available for use. Land is not depreciated (Note 6c).


The asset’s residual values, useful lives and depreciation methods are reviewed at each financial year end and adjusted prospectively, if appropriate.


For the years ended December 31, 2011 and 2010, the Company did not capitalize any financing costs since it did not have significant qualifying assets with prolonged acquisition periods.


Inventories for the operation of the telephone plant are valued based on the average cost method.


The net book value of any component of property, plant and equipment or any other significant item is removed from the balance sheet at the time of the asset’s disposition or when no future economic benefits are expected from its use or sale. Any gains or losses on the disposition of property, plant and equipment represent the difference between net proceeds of the disposition, if any, and the net book value of the item at the time of disposition. These gains or losses are recognized in earnings upon disposition.


The carrying value of property, plant and equipment is reviewed whenever there are indicators of impairment in such assets. Whenever an asset’s recovery value, which is the greater of the asset’s selling price and its value in use (the present value of future cash flows), is less than the asset’s net carrying value, the difference is recognized as an impairment loss. For the years ended December 31, 2011 and 2010, there were no indicators of impairment in these long-lived assets.


k) Leases


When the risks and benefits inherent to the ownership of the leased asset remain mostly with the lessor, they are classified as operating leases and rent expense is charged to results of operations when incurred.


Property and equipment lease agreements are recognized as capital leases if (i) the ownership of the leased asset is transferred to the lessee upon termination of the lease; (ii) the agreement includes an option to purchase the asset at a price that is expected to be sufficiently lower than the fair value at the date the option becomes exercisable ; (iii) the term of the lease is substantially the same as the remaining useful life of the leased asset; or (iv) the present value of minimum lease payments is substantially the same as the market value of the leased asset, net of any future benefit or residual value.


l) Licenses and trademarks


TELMEX records licenses at acquisition cost. The amortization period is based on the terms of the licenses, which range from 5 to 20 years. Trademarks are recorded at their estimated fair favlue at the date of acquisition, as determined by independent appraisers, and are amortized using the straight-line method over a 16-year period (Note 7).


m) Business combinations and goodwill


Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, measured at fair value at the acquisition date and the amount of any non-controlling interest in the acquiree. For each business combination, the acquirer measures the non-controlling interest in the acquiree either at fair value or at the proportionate share of the acquirer’s identifiable net assets. Acquisition-related costs incurred are expensed and included in administrative expenses.


The subsequent acquisition of non-controlling interest is considered a transaction between entities under common control and any difference between the purchase price and the carrying value of net assets acquired is recognized as an equity transaction.


Goodwill is initially measured as the excess of the acquisition price and the amount recognized for non-controlling interest, as measured at their fair value, over the net identifiable assets acquired and liabilities assumed.


n) Impairment in the value of long-lived assets


The Company has a policy in place for evaluating the existence of indicators of impairment in the carrying value of long-lived assets, including goodwill and intangibles. When there are such indicators, or in the case of assets whose nature requires an annual impairment analysis, the recovery value of the asset is estimated, which is the greater of its fair value, less any disposal costs, and its value in use. Value in use is determined by discounting estimated future cash flows, applying a discount rate after tax that reflect the time value of money and taking into consideration the specific risks associated with the asset. When the recovery value of an asset is below its net book value, impairment is considered to exist. In this case, the book value of the asset is reduced to the asset’s recovery value, recognizing the loss in results of operations for the respective period. Depreciation and/or amortization expense of future periods is adjusted based on the new accounting value determined for the asset over the asset’s remaining useful life. Impairment is analyzed for each asset individually, unless the asset does not generate cash inflows that are largely independent of those from other assets or group of assets (cash generating units).


In the estimation of impairment,the Company uses strategic plans, in which for periods longer than a year, projections are used based on such strategic plans applying a constant or decreasing expected growth rate.


The premises used to make the financial forecasts were the following:


Current subscribers and expected growth.

Market situation and penetration expectations

Investments in maintenance of the current assets

Market consolidation and synergies


Weighted average cost of capital (WACC) and market participants


To determine the discount rate, the Company uses WACC. For the variables used in its estimation, the Company utilized public information at the date closest to the financial statement reporting date.


The estimated discount rate used for the impairment tests conducted pursuant to IAS 36, considers the evaluation of market participant assumptions, considering their similarity to the Company’s businesses.


o) Accrued liabilities


Accrued liabilities are recognized whenever (i) the Company has current obligations (legal or constructive) resulting from a past event, (ii) when it is probable the obligation will give rise to a future outflow of economic resources for its settlement and (iii) the amount of the obligation can be reliably estimated.


When the effect of the time value of money is significant, the amount of the liability is determined as the present value of the expected disbursements to settle the obligation. The discount rate applied is determined on a pre-tax basis and reflects current market conditions at the statement of financial position date and, where appropriate, the risks specific to the liability. When discounting is used, an increase in the liability is recognized as an interest expense.


Contingent liabilities are recognized only when it is probable they will give rise to a future outflow of economic resources for their settlement. Also, commitments are only recognized when they will generate a loss.


p) Employee benefits


The cost of pension benefits and seniority premiums are recognized periodically during the years of service of personnel, based on actuarial computations made by independent actuaries using the projected unit-credit method (Note 12).


Actuarial (losses) gains are being amortized over a period of 11 years, which is the estimated average remaining working lifetime of Company employees.


q) Exchange differences


Transactions in foreign currency are recorded at the prevailing exchange rate on the day of the related transactions. Foreign currency denominated monetary assets and liabilities are valued at the prevailing exchange rate at the statement of financial position date. Exchange differences from the transaction date to the time foreign currency denominated monetary assets and liabilities are settled, as well as those arising from the translation of foreign currency denominated balances at the statement of financial position date, are charged or credited to results of operations.


r) Taxes on profits


Current and deferred income taxes are recorded as an income or expense in the statement of income, except to the extent that the tax arises from a transaction or event which is recognized, in the same or a different period, outside profit or loss, either in other comprehensive income or in equity.


Current income tax


Current income tax assets and liabilities for the current period are measured at the amount expected to be recovered from or paid to the tax authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date.


Deferred income tax


Deferred income taxes are recognized using the asset and liability method. Under this method, deferred income taxes are recognized on all differences between the financial reporting and tax values of assets and liabilities, applying the enacted income tax rate effective as of the statement of financial position date, or the enacted rates at that date that will be in effect when the deferred tax assets and liabilities are expected to be recovered or settled.


The Company periodically evaluates the possibility of recovering deferred tax assets and, if necessary, creates a valuation allowance for those assets that do not have a high probability of being realized.


s) Statement of income presentation


Costs and expenses shown in the Company’s statement of income are presented based on a combination of their nature and function, in accordance with industry practice since such classification allows for an appropriate evaluation of operating profit.


The “Operating profit” caption is shown in the statement of income since it is an important indicator used for evaluating the Company's operating results.


The “Other expenses, net” caption includes employee profit sharing for the current period of P.1,693,372 (P.1,998,105 in 2010).


t) Statement of cash flows


The statement of cash flows shows the entity’s cash inflows and outflows during the period. Also, the statement of cash flows begins with profit before income tax, followed by cash flows from operating activities, then cash flows from investing activities and finally cash flows from financing activities.


The statement of cash flows for the years ended December 31, 2011 and 2010 were prepared using the indirect method.


u) Earnings per share


Earnings per share are determined by dividing net income attributable to equity holders of the parent by the weighted-average number of shares outstanding during the year. In determining the weighted-average number of shares outstanding during the year, shares acquired by the Company have been excluded.


v) Concentration of risk


The main financial instruments used by the Company for financing purposes are bonds, domestic senior notes, bank loans, derivative financial instruments and accounts payable. The Company holds several financial assets, such as cash and cash equivalents, accounts receivable and prepaid expenses that come directly from its operations.


The main risks associated with the Company’s financial instruments are cash flow risk, liquidity risk, market risk and credit risk. The Company uses sensitivity analyses to measure the potential losses based on a theoretical increase of 100 basis points in interest rates and a 10% fluctuation in the relevant exchange rates. The Board of Directors approves the policies submitted by management to manage these risks.


Credit risk represents the potential loss from the failure of counterparties to completely comply with their contractual obligations. The Company is also exposed to market risks related to fluctuations in interest rates and exchange rates. In order to reduce the risks related to fluctuations in interest rates and exchange rates, the Company uses derivative financial instruments as hedges against its debt obligations.


Financial instruments which potentially subject the Company to concentrations of credit risk are cash and cash equivalents; trade accounts receivable, debt and derivative financial instruments. Pension fund assets are subject to market risk. The Company’s policy is designed to not restrict its exposure to any one financial institution; therefore, the Company’s financial instruments are maintained in different financial institutions.


The credit risk in accounts receivable is diversified because the Company has a broad customer base. The Company continuously evaluates the credit conditions of its customers and does not require collateral to guarantee collection of its accounts receivable. In the event the collection of accounts receivable deteriorates significantly, the Company’s results of operations could be adversely affected.


A portion of the Company’s cash surplus is invested in term deposits with financial institutions with high credit scores.


Sensitivity analysis


Exchange rates


The potential loss in the Company’s financial instruments at December31, 2011 that would have resulted from a hypothetical, instantaneous and unfavorable 10% change in currency exchange rates, in which the foreign currency debt is denominated, would have been P.675,204.Such a change in currency exchange rates would also have resulted in additional interest expense of P. 17,274 per year. The sensitivity analysis assumes an unfavorable change in the exchange rate, a fair value estimate of financial instruments and no change in the principal amount of such indebtedness.The sensitivity analysis includes the derivative financial instruments contracted as of December 31, 2011.


Interest rates


The potential loss in the Company’s financial instruments at December31, 2011 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 P.1,427,380. This effect would be fully attributable to the impact of the interest rate change on fixed-rate financial assets and liabilities. Additionally, it would have resulted in additional interest expense of P.381,411 per year.The sensitivity analysis assumes an unfavorable change in the interest rates applicable to each homogeneous category of financial assets and liabilities, a fair value estimate of financial instruments and no change in the principal amount of such indebtedness. The sensitivity analysis includes the derivative financial instruments contracted as of December 31, 2011. 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, this interest rate risk sensitivity analysis may overstate the impact of interest rate fluctuations for such financial instruments, as consistently unfavorable.


w) Segments


Segment information is presented based on information used by the Company in its decision-making processes (Note 18).


Local and long distance segment information differs from the information presented in the consolidated financial statements due to:



x) New accounting pronouncements


The IFRS improvements and modifications as well as the interpretations that have been published in 2011 are as follows. At the financial statements’ date, these standards have not become effective, and the Company has not early adopted them.

IFRS 9 “Financial Instruments”


The standard introduces new requirements for the classification and measurement of financial assets, permitting early adoption. It requires that all the financial assets be classified on the basis of the business model for the financial assets management and the characteristics of the contractual cash flows of the financial assets. Under this standard, the financial assets are measured either at amortized cost or fair value. Only the financial assets classified as measured at amortized cost should be tested for impairment. Its application is effective beginning January 1, 2015, with early adoption allowed.


IFRS 10 “Consolidated Financial Statements”


This statement replaces the section of IAS 27 “Consolidated and separate financial statements” which refers to accounting for consolidated financial statements. It also includes matters included in SIC 12 “Consolidation-Special purpose entities”. IFRS 10 establishes a sole model of control that applies to all entities (including special purpose entities or structured entities). The changes in IFRS 10 will require the Company’s management apply professional judgment when determining which entity is controlled and must be consolidated, as compared to the requirements of IAS 27.


IFRS 11 “Joint Arrangements”


IAS 31 “Interests in Joint Ventures” and SIC 13 “Jointly Controlled Entities – Non-Monetary Contributions by Venturers” are replaced by IFRS 11 “Joint Arrangements”. IFRS 11 used some of the terminology that was used in IAS 31, but with different meanings. While IAS 31 identifies three forms of joint ventures, IFRS 11 has only two forms of joint arrangements (joint venture and joint operation) when joint control exits. Because IFRS 11 uses the control principle in IFRS 10 to identify control, the determination if there is joint control may change. Also IFRS 11 removes the option to account for jointly-controlled entities using proportionate consolidation. Instead, those jointly-controlled entities must be accounted for using the equity method. For joint operations, those including jointly-controlled assets, start-up joint operations and start-up jointly-controlled entities, an entity must recognize its share of assets, liabilities, revenues and expenses in accordance with the applicable IFRS.


IFRS 12 “Disclosure of Interests in Other Entities”


IFRS 12 includes all the disclosures that were in IAS 27 related to consolidation, as well as the disclousres previously included in IAS 31 and IAS 28. These disclosures refer to the participation in related entities, joint arrangements, associated companies and structured entities. New disclosures are also required.


IFRS 13 “Fair Value Measurement”


IFRS 13 establishes a sole-source guide about fair value measurement, when such is required or allowed by IFRS. It does not change when an entity must use fair value. The standard changes the fair value definition to the price that could be received when an asset is sold, or the price that could be paid to settle a liability, in a normal transaction between market participants at the valuation date (exit price). In addition, IFRS 13 requires new disclosures.


The Company is still evaluating the impact that the aforementioned IFRS may have on the consolidated financial statements.


Improvement and modifications to existing IFRS are as follows:



Improvements and modifications

Mandatory application date

IAS 1

Presentation of Financial Statements

July 1, 2012

IAS 19

Employee Benefits

January 1, 2013


IAS 1 “Presentation of Financial Statements”


The IAS 1 modifications are related to the presentation of “other comprehensive income”, giving the option to present the statement of income and the statement of comprehensive income in a sole financial statement or as separate financial statements. It also changes paragraphs related with information that has to be presented in the statement of income and in other comprehensive income. These changes implicate modifications in other standards that are affected by this improvement. These changes are mandatory beginning on July 1, 2012. Early adoption is allowed, in which case, such must be disclosed.


IAS 19 “Employee Benefits”


On June 16, 2011, the IASB published modifications to IAS 19, “Employee Benefits”, which changes the accounting for defined benefit plans and termination benefits. The modifications require the recognition of the changes in the defined benefit obligation and plan assets when they occur, eliminating the corridor approach and accelerating the recognition of past service costs. Changes in the defined benefit obligation and plan assets are divided in three components: service cost, net interest of net (assets) liabilities of defined benefits and remeasurements of the net (assets) liabilities for defined benefits. The net interest is calculated using a rate of return for high quality corporate bonds, which may be less than the current rate used to calculate the expected return on the plan assets, resulting in a decrease to the profit for the current period. The modifications are effective beginning January 1, 2013, with early adoption allowed. Also retrospective application is required with certain exceptions.


The Company is still evaluating the impact that the aforementioned IFRS may have on the consolidated financial statements. However,the Company expectstheamended guidance, upon adoption, to result in the recognition of unamortizedactuariallosses,describedin Note 12, in “Accumulated other comprehensive income items” in equity.

To reduce the risks related to fluctuations in exchange and interest rates, the Company uses derivative financial instruments as hedges associated with its debt. The derivative financial instruments principally used by the Company are as follows:


Cross currency swaps


At December 31, 2011, the Company had cross currency swaps that hedge foreign currency denominated liabilities of P.29,363,270 (U.S.$2,101 million) (P.43,091,161 or U.S.$3,487 million at December 31, 2010) (P.54,557,723 or U.S.$4,178 at January 1, 2010), These cross currency swaps hedge the exchange rate and interest rate risks associated with bonds that mature in 2015 and 2019 in the total amount of U.S.$739 million and bank loans that mature from 2011 to 2018 of U.S.$1,362 million. These agreements allow the Company to fix the parity of such debt at a weighted-average exchange rate of P.10.9869 per U.S. dollar, as well as to set a fixed interest rate of 8.59% for the bond maturing in 2015 and a floating rate equal to the average 28-day TIIE less a specified margin for the bond maturing in 2019 and for the bank loans.


The change in the fair value of these cross currency swaps that offset the exchange gain on the foreign-currency denominated debt for the year ended December 31, 2011 was a net charge of P.4,625,428 (charge of P.2,108,445 in 2010).


Forwards dollar-peso


At December 31, 2011, the Company had no foreign currency forward contracts outstanding. At December 31, 2010, the Company had short-term foreign currency forwards with a notional amount of P.494,284 (U.S.$40 million) (P.3,199,382 or U.S.$245 million at January 1, 2010). For the year ended December 31, 2011, the Company recognized a net charge of P.12,094 (charge of P.97,295 in 2010), as part of the net exchange gain, due to changes in the fair value of these forwards.


Interest-rate swaps


At December 31, 2011, the Company had interest-rate swaps for an aggregate notional amount of P.12,840,470 (P.16,649,250 at December 31, 2010) (P.23,752,125 at January 1, 2010), to hedge the floating interest rate risk of its debt in Mexican pesos, fixing such rate at an average of 8.46%.


At January 1, 2010, the Company had cross currency coupon swap contracts that hedged interest payment cash flows of P.652,935 (U.S.$50 million).


In 2011, the Company recognized a net expense for these swaps in interest expense of P.958,835(P.1,687,679 in 2010).


In 2011, the ineffective portion of the cash flow hedges was a net expense of P.586,793 (P.506,815 in 2010), recognized in interest expense.


The Company’s derivatives are acquired in over-the counter markets, mostly from the same financial institutions with which it has contracted its debt.


Several of the Company’s agreements under which it has negotiated its derivative financial instruments require margin calls when the fair value of the derivatives exceeds the Company’s existing credit lines of P.5,940,948 (U.S.$425 million). At December 31, 2011, 58% of the Company’s outstanding derivatives correspond to these types of agreements; however, no margin calls had been required at such date.

12. Employee Benefits


Pension plans and seniority premiums


The majority of the Company’s employees are covered under defined benefit pension plans and seniority premiums. Pension benefits and seniority premiums are determined on the basis of compensation of employees in their final year of employment, their seniority, and their age at the time of retirement.


The Company has set up an irrevocable trust fund to finance these employee benefits and has adopted the policy of making contributions to such fund when it is considered necessary, which are deductible for Mexican corporate income tax and employee profit sharing purposes. The most important information related to employee benefits is as follows:

In 2011, the net actuarial loss of P.22,014,157 resulted from (i) the effect of an unfavorable actuarial variance of P.16,988,768 due to the behavior of the plan assets resulting from a decrease in the value of the trust fund’s investments in shares of companies and in fixed-yield investments due to variances in reference rates, and (ii) an actuarial loss of P.5,025,389 attributable principally to the fact that the number of employees who retired was greater than the number estimated at the beginning of the year, and the salary and pension benefits of the retired employees were higher than estimated at the beginning of the year.


In 2010, the net actuarial loss of P.6,527,106 resulted from (i) the effect of a favorable actuarial variance of P.1,081,612 due to the behavior of the plan assets resulting from an increase in the value of the trust fund’s investments in shares of companies and in fixed-yield investments due to variances in reference rates, and (ii) an actuarial loss of P.7,608,718 attributable principally to the fact that the number of employees who retired was greater than the number estimated at the beginning of the year, and the salary and pension benefits of the retired employees were higher than estimated at the beginning of the year.

14. Commitments and Contingencies


Commitments


At December 31, 2011, TELMEX has commitments for the purchase of equipment of P.10,143,202 (P.4,563,286 in 2010), which include P.1,155,645 (P.1,338,560 in 2010) of commitments with related parties. Payments made under the related purchase agreements aggregated to P.3,974,739 in 2011 (P.2,628,469 in 2010).


Contingencies


a) In November 2005, COFETEL issued the guidelines for making changes to local service areas. In April 2006, Teléfonos de México, S.A.B. de C.V. filed a motion for an administrative review of COFETEL’s guidelines for modifying the local service areas. Such motion was denied by the Communications Ministry (Secretaría de Comunicaciones y Transportes, or SCT) and is currently in litigation before the Third Regional Metropolitan Chamber of the Federal Tax and Administrative Court.


In March 2007, COFETEL ordered the consolidation of a package of 70 local service areas and a package of 2 local service areas while, in September 2008 it ordered the consolidation of another package of 125 local service areas and in December 2008, it ordered the consolidation of one local service area, each with its own schedule. Teléfonos de México, S.A.B. de C.V. has challenged COFETEL’s orders through the corresponding legal procedures.


In November 2009, in compliance with the ruling issued by the Full Circuit Court in Administrative Matters, the court declared the resolutions issued by COFETEL to be null and void.


If the validity of COFETEL’s ruling is eventually recognized, COFETEL may be able to re-initiate proceedings to require the consolidation of the local service areas.


Should the consolidation requirement ever become effective, there could be an adverse effect on the Company’s long-distance revenues.


The Company believes, based on the advice of external lawyers who are handling this matter, that although the Company’s arguments are well-founded, there is no certainty that Teléfonos de México, S.A.B. de C.V. will obtain favorable results.


b) Since 2007, the Federal Commission of Economic Competition (COFECO) initiated eight investigations to evaluate if Teléfonos de México, S.A.B. de C.V. (onward “Telmex”) and Teléfonos del Noroeste, S.A. de C.V., (onward “Telnor”) have substantial power and engages in monopolistic practices in certain markets.


The preliminary findings of four of these probes have been issued, in which COFECO has determined that Telmex and Telnor have substantial control in the following areas: (i) termination of public switched traffic; (ii) origination of public switched traffic; (iii) local transit services; and (iv) leasing of lines or circuits. Telmex and Telnor have expressed their disagreement with the proceedings, and later challenged the findings and submitted evidence against the allegations.


In the four markets in question, COFECO has already confirmed its resolutions and Telmex and Telnor filed the applicable motions for appeal, which COFECO denied. Telmex and Telnor have filed relief (amparo) proceedings against COFECO's denial of the motions for appeal. The rulings in some of these relief proceedings have already been handed down, while others are still pending.


In the case of the origination of public switched traffic and the leasing of lines or circuits markets, the courts upheld the denial of the motions for appeal filed by Telnor, which effectively upheld COFECO’s judgment that Telnor had substantial control over these markets.


In the case of the origination of public switched traffic market, through a proceeding, the COFETEL may mandate specific obligations for Telnor in such market.


In the case of the wholesale market for leasing of private circuits, in October 2011, the SCT and COFETEL submitted a draft of an agreement regarding the specific obligations for the Company related to prices, service quality, and information, for review by the Federal Commission for the Improvement of Regulations (COFEMER). If COFEMER were to issue a complete final ruling on this draft project and COFETEL were to publish the agreement in the Official Gazette, the Company believes that this could have a negative effect on the Company’s revenues from these services and, by extension, on its results of operations as a whole.


In the case of the termination of public switched traffic market, by way of its denial of the Company’s motions for appeal, COFECO has already confirmed its original ruling that Telmex and Telnor have substantial control. As a result of this confirmation, Telmex and Telnor filed relief (amparo) proceedings, which are still pending resolution.


Lastly, in the case of the transit services rendered to other long-distance services providers related to the package of 198 local service areas, Telmex and Telnor are waiting for rulings on the relief (amparo) proceedings filed by them against COFECO’s final reports in which it determined that Telmex and Telnor have substantial control over this market.


If the disputed resolutions are ultimately upheld, COFETEL, after completing the applicable procedure, may establish specific obligations for the Company regarding the prices, quality of services and information in the markets in question. The exact nature of these regulations and their impact on the business cannot be known in advance, but they will likely reduce the Company's flexibility and its ability to adopt competitive market policies. It is also impossible to predict what timeframe the Company will take to adopt the new regulations and whether it will actually be able to do so.


Regarding the four remaining probes, as a result of its probe into the fixed-network interconnection services market, COFECO has determined that Telmex engaged in monopolistic practices. Telmex has filed relief (amparo) proceedings against this ruling and their cases are pending resolution. Regarding the broad-band internet market for domestic residential customers and the interurban transport for switched long-distance traffic services markets, COFECO ordered the probes closed upon determining that there is no evidence that Telmex and Telnor engaged in monopolistic practices. Lastly, with respect to the local and national long-distance dedicated links wholesale leasing services market, COFECO issued and notified to Telmex and Telnor probable fault (Oficio de Probable Responsabilidad) which the Company will object.


There is no certainty as to what the outcome of these probes will be, but they may be against the interests of Telmex and Telnor and result in regulations, restrictions or monetary fines being imposed on both companies.


The Company believes, based on the advice of external lawyers who are handling this matter, that although the Company’s arguments are well-founded, there is no certainty that Telmex and Telnor will obtain favorable results.


c) The Mexican Social Security Institute (IMSS) audited Teléfonos de México, S.A.B. de C.V. for the 1997-2001 period. At the conclusion of the audit, IMSS determined that Teléfonos de México, S.A.B. de C.V. owed a total of approximately P.330,000 (historical amount), in taxes, fines, surcharges and re-expression for inflation at July 2, 2003. Teléfonos de México, S.A.B. de C.V. filed an appeal to nullify these findings and related assessment with the Federal Court of Justice for Tax and Administrative Matters. In accordance with Mexican law, by means of a trust fund established with a banking institution, the Company guaranteed payment of the tax assessment in the amount of P.568,869 through July 19, 2010. The Regional Metropolitan Chamber court nullified the ruling; however, IMSS filed a motion for appeal. In October 2009, the court handling the appeal ruled in favor of the Company. Therefore, the ruling issued on the nullity of the fee settlement schedules became final. Consequently, Teléfonos de México, S.A.B. de C.V. initiated proceedings to dissolve the trust fund guaranteeing the payment of the amounts sought by IMSS. The trust was dissolved on January 22, 2010, which was the date on which Teléfonos de México; S.A.B. de C.V. recognized the income from canceling this contingency.


As a result, since the tax liabilities have been annulled and the amount pledged in guaranty was returned to Teléfonos de México, S.A.B. de C.V. on January 22, 2010, this matter is considered closed.


d) On February 10, 2009, COFETEL published a Fundamental Technical Plan of Interconnection and Inter-operability, or the Fundamental Technical Plan in the Official Gazette. As it is currently worded, the Fundamental Technical Plan could have a negative impact on both Telmex and Telnor, and on the telecommunications sector in general, since it establishes certain obligations for telephone service providers.


Telmex and Telnor have legally challenged the plan through a number of available channels and have presented evidence to demonstrate the illegality and unconstitutionality of the Fundamental Technical Plan. Telmex’s case is pending resolution, while Telnor was granted relief (amparo) against the Fundamental Technical Plan. As a result of this ruling, the Fundamental Technical Plan shall no longer be applicable to Telnor and shall nullify any resolutions handed down against Telnor under the Plan.


The Company believes, based on the advice of external lawyers who are handling this matter, that although the Company’s arguments are well-founded, there is no certainty that Telmex and Telnor will obtain favorable results.

(1) Number of shares in millions.


The Company’s capital stock must be represented by no less than 20% of Series “AA common shares, which may be subscribed and acquired only by Mexican investors, and at all times must represent at least 51% of the common shares of total capital stock; Series “A” common shares, which may be freely subscribed, and must not exceed more than 19.6% of capital stock and no more than 49% of the common shares of total capital stock; both Series “AA” and “A” shares combined may not represent more than 51% of capital stock; and Series “L” shares, which have limited voting rights and may be freely subscribed, in a percentage when combined with the Series “A” shares may not exceed 80% of capital stock.


Voting rights


Each ordinary share of the Series “AA” and “A” entitles the holder to one vote at the general shareholders’ meetings. Each Series “L” share entitles the holder to one vote at all shareholders’ meetings in which holders of Series “L” shares are authorized to vote. In accordance with the Eighth Clause of the Company’s bylaws, holders of Series “L” shares only have the right to vote to designate two directors on the Board of Directors and their corresponding alternate directors, and on the following matters:





In order for the resolutions adopted in extraordinary shareholders’ meetings related to any of the matters on which the Series “L” shares are entitled to vote to be validated, the approval by a majority vote of the Series “AA” and Series “A” shareholders will be required.


Under Mexican law, the shareholders of any Series of shares are also entitled to vote as one class on any proposal that could adversely affect the rights of the shareholders of that particular series and the Company’s shareholders (including the Series “L” shareholders), which individually or collectively represent 20% or more of all capital stock could judicially oppose any shareholders’ resolution with respect to those resolutions for which such shareholders have the right to vote. The determination of whether a matter requires the vote by the holders of Series “L” shares under such basis would initially be made by the board of directors or by any other party that calls a shareholders’ meeting to decide on the resolution. A negative decision would be subject to judicial challenge by any affected shareholder, and a court would ultimately determine the necessity for a class vote. There are no other procedures for determining whether a proposal requires a class vote, and Mexican law does not provide extensive guidance on the criteria to be applied in making such a determination.


b) In 1994, the Company initiated a program to purchase its own shares. The cost of the repurchased shares, in the amount that exceeds the portion of capital stock corresponding to the repurchased shares, is charged to retained earnings.


At a regular shareholders’ meeting held on March 3, 2009, the shareholders approved an increase of P.10,000,000 in the total authorized nominal amount for the repurchase of the Company’s own shares. The remainder of the previously authorized amount was P.340,868, bringing the total maximum amount to be used for this purpose to P.10,340,868.


In 2011, the Company acquired 128.5 million Series “L” shares for P.1,358,773.


In 2010, the Company acquired 33.9 million Series “L” shares for P.339,746 and 6,906 Series “A” shares for P.76.


At December 31, 2011 and 2010 and at January 1, 2010, the Company had 14,202 million (14,160 million Series “L” and 42 million Series “A” shares), 14,074 million (14,032 million Series “L” y 42 million Series “A” shares) and 14,040 million (13,998 million Series “L” and 42 million Series “A” shares) held as treasury shares, respectively.


c) In conformity with the Mexican Corporations Act, at least 5% of net profit 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.


d) At a regular meeting held on April 28, 2011, the shareholders agreed to declare a cash dividend of P.0.55 per outstanding share, to be paid in four installments of P.0.1375 each in June, September and December 2011, and in March 2012. In March 2011, the Company paid the fourth installment of P.0.1250 per outstanding share, which was authorized at the regular meeting held on April 29, 2010.


At a regular meeting held on April 29, 2010, the shareholders agreed to declare a cash dividend of P.0.50 per outstanding share, to be paid in four installments of P.0.1250 each in June, September and December 2010, and in March 2011. In March 2010, the Company paid the fourth installment of P.0.1150 per outstanding share, which was authorized at the regular meeting held on April 29, 2009.


The cash dividends paid in 2011 and 2010 was P.9,508,964 and P.8,736,965, respectively.



17. Income Tax and Flat-Rate Business Tax


a) Through December 31, 2009, the corporate income tax rate was 28%. Under the Mexican Tax Reform Law approved on December 7, 2009, the corporate income tax rate was increased from 28% to 30% for the period from January 1, 2010 through December 31, 2012, and will be scaled back to 29% in 2013, and to 28% in 2014 and future years.


b) On October 1, 2007, the Flat-Rate Business Tax (FRBT) Law was published and became effective as of January 1, 2008.


The FRBT is computed by applying the applicable rate to income determined on the basis of cash flows, which is determined by deducting authorized deductions from all income collected from those activities that are subject to the tax. Certain FRBT credits also may be deducted from the FRBT payable. The FRBT rate is 17.5%.


For the years ended December 31, 2011 and 2010, the Company had no FRBT payable and, based on its tax projections, estimates that it will not be subject to the payment of FRBT in subsequent years.


c) An analysis of the income tax provision is as follows:

Quarterly Report of Derivative Financial Instruments


I. Executive Summary

As of December 31, 2011, Teléfonos de México, S.A.B. de C.V. (“Telmex” or the “Company”) had cross currency swap agreements in the equivalent of U.S.$2,101 million, which have hedged the exchange rate and interest rate risks related to the bonds with maturity in 2015 and 2019 for a total amount of U.S.$739 million and loans with maturities from 2012 to 2018 for a total amount of U.S.$1,362 million. These hedges allowed us to fix the exchange rate of our debt on a weighted average exchange rate of P.10.9869 Mexican pesos per US dollar and an average interest rate of 28-day TIIE less a specified margin, as well as to set a fixed rate of 8.59% for the bond maturing in 2015.

In March 2011, cross currency swaps were unwound in the equivalent of U.S.$351 million, which partially hedged the bonds with maturity in 2015 and 2019, since the Company acquired U.S.$366 million of such bonds from América Móvil, S.A.B. de C.V. (América Móvil) to extinguish them; in addition, U.S.$40 million of cross currency swaps and U.S.$40 million of forward contracts became due.

In September 2011, cross currency swaps were unwound in the equivalent of U.S.$135 million, which partially hedged a loan with América Móvil due in October 2011.

In October 2011, cross currency swaps became due in the equivalent of U.S.$355 million, which partially hedged the loan with América Móvil due in the same month. In addition, cross currency swaps were unwound in the amount of JPY $ 19,891 million (equivalent to U.S.$ 259 million) which hedged the credit in Japanese Yens with maturity in 2014.

In November 2011, cross currency swaps were unwound in the equivalent of U.S.$220 million, which partially hedged the bonds with maturity in 2015.

At December 31, 2011, the Company had interest rate swaps in Mexican pesos for P.12,840 million to hedge the floating rate risk in local currency, fixing it at an average of 8.46%.

During the third quarter of 2011, interest rate swaps in the equivalent of P.$3,809 million, which hedged the risk of floating rate in domestic currency, were restructured. This restructuring did not affect the results of the period.

No new derivative instruments were contracted.

These transactions have been carried out based on the policies, strategies and guidelines of the Company.


II. Qualitative and Quantitative Information

i. Management discussion on the policies for using derivative instruments

The policies for using derivative instruments indicated below, are part of the Financial Risk Management Policies approved by the Board of Directors, which describe the general guidelines for the identification, management, measurement, monitoring and control of financial risks that may affect the operation or expected results of Telmex.

The Audit Committee, as a delegated body of the Board of Directors, is responsible to analyze and define the strategy to hedge or mitigate risks related to exchange rate and interest rate fluctuations of the Company’s debt, assess the Management’s results in handling derivative instruments according to the established policies and inform the Board of Directors for their knowledge and, if appropriate, ratification.

Objective to enter into derivative transactions and selected instruments

With the purpose of reducing the risks related to the variations of exchange rate and interest rate, the Company uses derivative instruments associating the hedges with the debt. The derivative instruments that have been selected are, mainly:

  1. instruments for purchasing US dollars at a specified future time (forwards);

  2. instruments that involve the exchange of principal and interest from one currency to another (cross currency swaps); and

  3. instruments to fix the floating interest rates of the debt (interest rate swaps).

The Company uses these instruments in a conservative manner, without any speculative purpose.

Hedge strategies

When the market conditions are favorable, the Company’s Management determines the amounts and goal parameters under which the hedge agreements are contracted. This strategy seeks to reduce the risk exposure of abnormal market fluctuations in the main variables that affect our debt, including exchange rate and interest rate, to maintain a solid and healthy financial structure. Most of our derivative instruments have been designated and qualify as cash flow hedges.

Trading markets and eligible counterparties

The derivative instruments are traded in over-the-counter-markets, i.e. out of an institutionalized exchange market. The financial institutions and counterparties with which the Company enters into such derivative instruments are considered to have a proven reputation and solvency in the market, which allows us to balance our risk positions with such counterparties.

It is a policy of the Company to try to avoid the concentration of more than 25% (twenty five per cent) of the total derivatives position in a single counterparty.

Also, the Company only uses derivative instruments that are of common use in the markets, and therefore, can be quoted by two or more financial institutions to assure the best conditions in the negotiation.

Policies for the appointment of calculation and valuation agents

Given that the Company uses derivative instruments of common use in the market, it appoints a third independent party that is responsible to provide the market price of such instruments. These prices are compared by the Company with the prices provided by the financial intermediaries; and, in certain transactions, the counterparty is able to act as valuation agent under the applicable documentation if it is a financial institution with a proven reputation.

Main terms and conditions of the agreements

It is a policy of the Company that the amount, date and interest rate conditions of the debt to be hedged, if possible, have to coincide with the terms of the hedges, that is usual for this type of transactions in the different markets where it operates.

All the transactions with derivative instruments are made under the ISDA Master Agreement (International Swap Dealers Association) standardized and duly executed by the legal representatives of the Company and the financial institutions, and in the case of counterparties in México, pursuant to the uses and practices of the market in our country.

Margin policies, collaterals and lines of credit

In some cases, the Company has entered into an accessory agreement to the ISDA Master Agreement with the financial institutions, the Credit Support Annex, which sets forth an obligation to grant collaterals for margin calls in case the mark to market value exceeds certain credit limits (threshold amount).

The Company has the policy to keep a close watch of the volume of the transactions entered into with each financial institution in order to avoid, if possible, any margin call.

Processes of levels of authorization required by type of negotiation

All derivative instrument transactions are executed by the Chief Financial Officer, the Assistant Director of Budget and Financial Planning or the Treasury Operation Manager, who are the only individuals registered with the financial institutions for such purposes.

Existence of an independent third party that reviews such processes

Both, the fulfillment of the Corporate Governance Guidelines and the measurement of effectiveness of the derivative instruments, to comply with the International Financial Reporting Standards, are discussed with the independent auditors that validate the reasonable accounting application of the effect of such instruments in the financial statements of the Company.


ii. Generic description of the valuation techniques and accounting policies

As previously stated, derivative instruments are carried out by the Company only for hedging purposes. The measurement of the effectiveness of the hedges is made in a prospective and retrospective manner. For the prospective valuation, we use statistic techniques that allow us to measure in what proportion the change in the value of the hedged debt (primary position) is compensated by the change in the value of the derivative instrument. The retrospective valuation is made by comparing the historic results of the debt flows with the flows of the respective hedges.

The effectiveness of the Company’s derivatives used for hedging purposes is evaluated prior to their designation as hedges, as well as during the hedging period, which is performed at least quarterly. Whenever it is determined that a derivative is not highly effective as a hedge or that the derivative ceases to be a highly effective hedge, the Company ceases to apply hedge accounting for the derivative on a prospective basis. At December 31, 2011, there were no gains or losses recognized due to changes in the accounting treatment for hedges.

Derivative financial instruments are recognized in the balance sheet at their fair values. The effective portion of the cash flow hedge’s gain or loss is recognized in “Accumulated other comprehensive income items” in stockholders’ equity, while the ineffective portion is recognized in current year earnings. Changes in the fair value of derivatives that do not qualify as hedges are immediately recognized in earnings.

The change in fair value recognized in earnings related to derivatives that are accounted for as hedges is presented in the same income statement caption as the gain or loss of the hedged item.

At December 31, 2011, our cross currency swaps position is deemed to be highly effective, with an effectiveness factor of approximately 94.5%

Also, P.8,000 million of our interest rate swaps are deemed to be highly effective, with an effectiveness factor of approximately 83.3%, while the remaining P.4,840 million were considered ineffective.

Adjustments due to early adoption of International Financial Reporting Standards

Beginning in 2012, Mexican issuers with securities listed on a Mexican securities exchange will be required to prepare financial statements in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). Issuers may voluntarily report using IFRS before the change in the reporting standards becomes mandatory.

The Company, with the respective authorization of its Board of Directors, Audit Committee, the Mexican Stock Exchange and the Mexican National Banking and Securities Commission, decided to adopt IFRS as issued by the IASB as of December 31, 2011, using a transition date as of January 1. 2010.

International Accounting Standard 39, Financial Instruments: Recognition and Measurement , requires that credit risk is taken into account when determining fair value of financial instruments. For the transition from Mexican Financial Reporting Standards (Mexican FRS) to IFRS, Telmex adjusted the fair value of derivative assets and liabilities determined under Mexican FRS with the non performance risk. Therefore, the fair value of derivative assets and liabilities position is net of a credit valuation adjustment attributable to Telmex’s “own credit risk” and derivative counterparty default risk. Non performance risk amounted P.470 million at December 31, 2011 (P.247 million at December 31, 2010).


iii. Management discussion on internal and external liquidity sources to meet the requirements related to derivative instruments

It is estimated that the Company’s cash generation has been enough to service debt and the established derivative instruments to hedge the risks associated with such debt.


iv. Changes in the exposure to the main identified risks and its management

The identified risks are those related to the variations of the exchange rate and interest rate. Given the direct relationship between the hedged debt and the derivative instruments and that they do not have any variables that could affect or terminate the hedge in advance, the Company does not foresee any risk that such hedges could differ from the original purpose for which the hedges were contracted.

In March 2011, cross currency swaps were unwound in the equivalent of U.S.$351 million, which partially hedged the bonds with maturity in 2015 and 2019; in addition, U.S.$40 million of cross currency swaps and U.S.$40 million of forward contracts became due.

In September 2011, cross currency swaps were unwound in the equivalent of U.S.$135 million, which partially hedged the a loan with América Móvil due in October 2011.

In October 2011, cross currency swaps became due in the equivalent of U.S.$355 million, which partially hedged the loan with América Móvil due in the same month. In addition, cross currency swaps were unwound in the amount of JPY $ 19,891 million (equivalent to U.S.$ 259 million) which hedged the credit in Japanese Yens with maturity in 2014.

In November 2011, cross currency swaps were unwound in the equivalent of U.S.$220 million, which partially hedged the bonds with maturity in 2015.

No new derivative instruments were contracted.

In 2011 the change in the fair value of the cross currency swaps that offset the exchange loss of the foreign-currency denominated debt was a net credit of P.4,625 million (net charge of P.2,108 million in 2010).

Additionally, in 2011 the Company recognized in interest expense a net expense for interest rate swaps of P.959 million (net expense of P.1,688 million in 2010).

In 2011, the ineffective portion of cash flow hedges was a net expense of P.587 million (net expense of P.507 million in 2010), recognized in interest expense.

During 2011, no margin calls had been required. To date, there has not been any breach in the terms and conditions of the respective agreements.

(*) Of our hedge agreements, 58% of the total hedge amount include margin calls, when the market value exceeds the amounts of the lines of credit that we have in the amount of US$425 million.

(1) These swaps hedge the debt position in US dollars, with the obligation of paying floating rate in Mexican pesos at an average of TIIE less a specified margin and with an average life of 3 years.

(2) In September these swaps hedged debt position in Yens with the obligation of paying $2,000 million in Mexican pesos (equivalent to USD$259 million) at a floating rate and with maturity in February 2014. These contracts were unwound in October 2011.

(3) These agreements hedge debt position in Mexican pesos at a floating rate, fixing it at an average of 8.46% and with an average life of 5 years.


III. Sensitivity Analysis

In the case of the Company, the sensitivity analysis for changes in the fair value of derivative financial instruments that are in the correlation range of 80% to 125% of effectiveness is not presented, since they are carried out for hedging purposes and therefore, any change in variables (i.e. exchange rates and interest rate) that affect the cash flows of the hedged debt (primary position) would be offset by the changes in the cash flows of the derivative instruments.

Sensitivity analysis for potential losses in fair value considering scenarios of hypothetical, instantaneous and unfavorable changes in interest rates is presented for derivative financial instruments deemed ineffective.

A hypothetical decrease in the value of the underlying asset (interest rate) of 10%, 25% and 50%, would result in an additional charge to the Company’s income statement as follows:
