Highlights

4th Quarter 2010

· 20 years of technological development.- At TELMEX, we are celebrating 20 years as a private-sector company. During this time, we have modernized, upgraded and transformed from a company that only offered telephony services to become the leading telecommunications services company in the country in a highly competitive market. For the past two decades our commitment has been to connect Mexico through the best technological platform, offering our customers the best services and conditions, and driving technological innovation through information technology and communications.

· As the leading telecommunications company in Mexico, TELMEX will continue to reduce the prices of our services and transfer to our customers the benefits derived from our significant investments, innovation, higher productivity and technological advances.

· Additionally, we continue promoting infinitum high-speed Internet access and, thanks to our customers’ preference, at December 31, 2010, we served 7.4 million broadband accesses in which infinitum is appreciated as the best connection for its quality, service, price and consistently high speed.

· At year-end 2010, we had 15.6 million lines, 291,000 fewer compared with December 2009. Of these, 13.8 million lines are in 198 LSA (Local Service Areas) where competitors are present. The remaining 1.8 million lines are in 199 LSA (Local Service Areas) in communities where competitors are not present and which cover more than 900 thousand square kilometers, or 46% of the national territory. These lines generate revenues mainly from long distance and call termination. Extending service across the large expanse of our country requires significant investments for network growth and modernization and ongoing maintenance and operating expenses.

· Our Driving Technological Innovation Program has achieved a number of significant milestones:

· Information Technologies: 1,242 IT professionals have been trained at no cost to the participants.

· Education and Digital Culture: At year-end we had 3,500 Bibliotecas and Aulas Digitales TELMEX in operation (TELMEX Digital Libraries and Computer Class Rooms) nationwide, benefiting more than 2 million people.

· Connectivity in the Country: We have more than 3,500 WiFi Móvil en infinitum sites installed.

· Universidad Tecnológica Digital (Digital Technological University).- During 2011 its operations will expand to offer higher-education courses through the Internet.

· During the fourth quarter of 2010, revenues totaled 27.958 billion pesos, a decrease of 6.0% compared with the same period of 2009. Revenues from local services, long distance and interconnection decreased 7.3%, 8.2% and 8.9%, respectively. For the twelve months, revenues decreased 4.6% compared with 2009.

· From October to December, EBITDA (1) totaled 11.087 billion pesos, producing a margin of 39.7%, because the initiatives to reduce operating costs were not able to offset the decrease in revenues. Operating income totaled 6.678 billion pesos, with a margin of 23.9%.

· Net incom e in the fourth quarter totaled 3.389 billion pesos. In the quarter, earnings per share were 19 Mexican cents, 29.6% lower than the same period of last year, and earnings per ADR (2) were 30 US cents, a decrease of 26.8% compared with the fourth quarter of 2009.

· At year-end, 2010, total debt was the equivalent of 6.031 billion dollars. Total net debt (3) was equivalent to 5.425 billion dollars, 1.352 billion dollars less than December 31, 2009.

Operating Results

Lines and local traffic

At year-end 2010, we had 15.6 million lines, 291,000 fewer compared with December 2009. Of these, 13.8 million lines are in 198 LSA (Local Service Areas) where competitors are present. The remaining 1.8 million lines are in 199 LSA (Local Service Areas) in communities where competitors are not present and which cover more than 900 thousand square kilometers, or 46% of the national territory. These lines generate revenues mainly from long distance and call termination. Extending service across the large expanse of our country requires significant investments for network growth and modernization and ongoing maintenance and operating expenses.


During the fourth quarter, local calls decreased 6.5% compared with the same period of 2009, totaling 4.675 billion local calls. The decline reflected the lower number of billed lines due to the growth in cellular telephony services and competition from other operators, as well as the customers’ changing consumption profile.

Long distance

From October to December, domestic long distance (DLD) traffic decreased 7.6% compared with the same quarter of 2009, totaling 4.446 billion minutes, mainly due to the decrease in termination traffic with cellular telephony operators and other long distance operators.

In the quarter, outgoing international long distance (ILD) traffic increased 20.0% compared with the fourth quarter of 2009, totaling 368.9 million minutes. Among factors contributing to this increase were the inclusion of this service in the infinitum packages and the increase of termination traffic from cellular operators. Incoming international long distance traffic increased 14.5% compared with the fourth quarter of 2009, totaling 2.015 billion minutes. The incoming-outgoing ratio was 5.5 times .

Interconnection

In the fourth quarter, interconnection traffic totaled 10.554 billion minutes, 1.2% lower than the same quarter of 2009, due to the 1.3% decrease in interconnection traffic with other local and long distance operators and the 1.5% decrease in traffic related to calling party pays services.

Internet access

At TELMEX, we remain committed to offering the best services to our customers and driving the nation’s digital culture through advancing information technology and communications (ITC). We continue promoting infinitum high-speed Internet access. Thanks to our customers’ preference, we served 7.359 million broadband accesses at December 31, 2010. infinitum is appreciated as the best connection for its quality, service, price and consistently high speed.


This growth has been supported by the sales of more than 2.8 million computers since 1999 and by the promotion of our telecommunications service packages, which offer broadband Internet access and several voice services at attractive prices.


Financial Results

The following financial information for 2010 and 2009 is presented in nominal pesos, according to Mexican Financial Reporting Standards.

Revenues: In the fourth quarter, revenues totaled 27.958 billion pesos, a decrease of 6.0% compared with the same period of the previous year. Revenues related to data services decreased 7.4% because revenues from a significant security and information technologies project were recognized in the fourth quarter of 2009, which affected the comparison with revenues of the fourth quarter of 2010. Local, long distance and interconnection revenues decreased 7.3%, 8.2% and 8.9%, respectively.

Costs and expenses: In the fourth quarter of 2010, total costs and expenses were 21.280 billion pesos, 3.1% lower than the same period of the previous year, mainly due to lower expenses related to information technology and communications (ITC) projects, lower charges for uncollectables and lower interconnection costs.

EBITDA (1) and o perating income : EBITDA (1) totaled 11.087 billion pesos in the fourth quarter of 2010, a decrease of 9.4% compared with the same period of the prior year. The EBITDA margin was 39.7%. Operating income totaled 6.678 billion pesos in the fourth quarter and the operating margin was 23.9%.

Financing cost: In the fourth quarter, financing co st produced a charge of 847 million pesos. This was a result of: i) a net interest charge of 833 million pesos, 34.7% lower than the October-December period of 2009 which included debt reduction and recognition of the market value of interest rate swaps, and ii) a net exchange loss of 14 million pesos due to the fourth-quarter exchange rate appreciation of 0.144 pesos per dollar and the 3.527 billion dollars in dollar-peso hedges in effect at the end of December 2010.

Net income: In the fourth quarter, net income was 3.389 billion pesos, 32.1% lower than the same period of the previous year. Earnings per share were 19 Mexican cents, 29.6% lower than the fourth quarter of 2009, and earnings per ADR (2) were 30 US cents, a decrease of 26.8% compared with the same period of the previous year.

Investments: In the fourth quarter , capital expenditures (Capex) were the equivalent of 323.7 million dollars, of which 65.5% was used for growth and infrastructure projects in the data business, connectivity and transmission networks. For the twelve months, investments totaled 839.6 million dollars.

Repurchase of own shares : During the fourth quarter, the company used 328.799 million pesos to repurchase 32.885 million shares.

Debt: Total debt at December 31, 2010, was the equivalent of 6.031 billion dollars, of which 84.0% is long-term, 50.1% has fixed rates considering interest rate swaps, and 59.1% is in foreign currency, equivalent to 3.567 billion dollars. To minimize risks from variations in the exchange rate, at December 31, 2010, we had dollar-peso hedges for 3.527 billion dollars.

During the quarter, we amortized 1.0 billion dollars corresponding to the anticipated payment of tranch B of the syndicated loan which was issued in August 2006 and scheduled to mature in October 2011. TELMEX used 500 million dollars of its own resources and the rest was refinanced.

Total net debt (3) decreased during the last 12 months the equivalent of 1.352 billion dollars, bringing the total to 5.425 billion dollars.

1. Description of the Business and Significant Accounting Policies

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 interconnection of subscribers 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 rates.

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

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) (TELMEX’s controlling stockholder) and Telmex Internacional, S.A.B de C.V. (Telmex Internacional). 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, thus, América Móvil indirectly owned 59.1% of the outstanding shares of TELMEX by then. América Móvil launched an additional offer on November 19, 2010, which ended on December 17, 2010, increasing to 59.5% its indirect ownership of the outstanding shares of TELMEX.

On March 15, 2011, TELMEX’s Audit Committee and management authorized the issuance of the accompanying consolidated financial statements and these notes as of December 31, 2010 and 2009. These financial statements also must be approved by the Company’s Board of Directors and stockholders at their next meetings.

II. 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 Mexican Financial Reporting Standards, are described below:

a) 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 the companies operate in the telecommunications sector or provide services to companies operating in this sector.

Subsidiaries are fully consolidated from the date of acquisition, being the date on which TELMEX obtains control, and continue to be consolidated until the date when such control ceases. The financial statements of the subsidiaries are prepared for the same reporting period as TELMEX, using consistent accounting policies.

1. Description of the Business and Significant Accounting Policies (continued)

All intercompany balances and transactions have been eliminated in the consolidated financial statements. Noncontrolling interest refers to certain subsidiaries in which the Company does not hold 100% of the shares.

Equity investments in affiliated companies over which the Company exercises significant influence is accounted for using the equity method, which basically consists of recognizing TELMEX’s proportional share in the net income or loss and the stockholders’ equity of the investee (see Note 6).

The results of operations of the subsidiaries and affiliates were included in TELMEX’s financial statements as of the month following their acquisition.

ii) Translation of financial statements of foreign subsidiary and affiliate

Beginning January 1, 2008, the financial statements of the foreign subsidiary and affiliate are either consolidated or accounted for based on the equity method, as the case may be, once the financial statements have been adjusted to conform to Mexican Financial Reporting Standards in the corresponding local currency, and are then translated to the reporting currency. All the assets and liabilities of the foreign subsidiary are translated to Mexican pesos at the prevailing exchange rate at year-end. Stockholders’ equity accounts are translated at the prevailing exchange rate at the time capital contributions were made and earnings were generated. Revenues, costs and expenses are translated at the historical exchange rate. Translation differences are recorded in stockholders’ equity in the line item “Effect of translation of foreign entities” under “Accumulated other comprehensive income items.”

b) Recognition of the effects of inflation on financial information

Upon adoption of Mexican FRS B-10, Effects of Inflation , which became effective on January 1, 2008, the Company ceased to recognize the effects of inflation in its financial information because it currently operates in a “non-inflationary economic environment”.

The financial statements for the years ended December 31, 2010 and 2009 are expressed in nominal pesos, except for those non-monetary items that included inflation effects through December 31, 2007. Subsequent additions are recognized at historical cost.

Capital stock and retained earnings were re-expressed for inflation through December 31, 2007 based on the Mexican National Consumer Price Index (NCPI).

1. Description of the Business and Significant Accounting Policies (continued)

c) Recognition of revenues

Revenues are recognized at the time services are provided. 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 rates. 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 rates 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 Mexican Financial Reporting Standards 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.

e) Cash and cash equivalents

Cash at banks earns 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.

1. Description of the Business and Significant Accounting Policies (continued)

f) 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 amount of either paying or receiving a fixed interest rate and the cash flow from receiving or paying a floating interest rate, based on a notional amount 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 instrument and the hedged position; ii) the objectives for risk management; and iii) the strategy for conducting hedging transactions. This process takes into account the relationship between the cash flow of the derivatives with the cash flows of the corresponding assets and liabilities recognized in the balance sheet.

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. During the years ended December 31, 2010 and 2009, 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, 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 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.

1. Description of the Business and Significant Accounting Policies (continued)

g) Allowance for doubtful accounts

The allowance for doubtful accounts is determined based on the Company’s historical experience, the aging of the balances and general economic trends, as well as an 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 uncollectibility of accounts receivable from related parties is evaluated annually based on an examination of each related party’s financial situation and the markets in which they operate.

h) Inventories

Inventories for sale are valued at average cost. The carrying value of inventories is not in excess of their net realizable value.

i) Plant, property and equipment

Through December 31, 1996, plant, property and equipment and construction in progress were re-expressed based on the acquisition date and cost, applying the factors derived from the specific indexes determined by the Company and validated by an independent appraiser.

From January 1, 1997 through December 31, 2007, plant, property and equipment and construction in progress acquired abroad were re-expressed based on the rate of inflation of the respective country of origin and the prevailing exchange rate at the balance sheet date (specific indexation factors). Plant, property and equipment of domestic origin were re-expressed based on the NCPI.

Telephone plant and equipment are depreciated using the straight-line method based on the estimated useful lives of the related assets (see Note 4 b).

The carrying value of plant, property, plant and equipment is reviewed whenever there are indicators of impairment in the carrying value of 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 amount, the difference is recognized as an impairment loss. For the years ended December 31, 2010 and 2009, there were no indicators of impairment in the value of the Company’s plant, property and equipment.

An item of plant, property and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the income statement when the asset is derecognized.

1. Description of the Business and Significant Accounting Policies (continued)

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

The Company has not capitalized any financing costs since it has no significant qualifying assets with prolonged acquisition periods.

Reclassification of comparative information

TELMEX has reclassified the caption inventories for operation of the telephone plant, net as part of the caption plant, property and equipment, net. The Company concluded that this classification better reflects the underlying nature of the asset.

Inventories for the operation of the telephone plant are valued at average cost, and through December 31, 2007 were re-expressed on the basis of specific indexes. The carrying value of inventories is similar to replacement value, which is not in excess of their market value.

j) 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.

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 reduced price; (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.

k) Licenses and trademarks

TELMEX records licenses at acquisition cost and, through December 31, 2007, re-expressed them based on the inflation rate of the country in which the license was acquired. 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 values at the date of acquisition, as determined by independent appraisers, and are amortized using the straight-line method over a sixteen-year period (see Note 5).

1. Description of the Business and Significant Accounting Policies (continued)

l) 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 of acquisition date and the amount of any noncontrolling interest in the acquiree. For each business combination, the acquirer measures the noncontrolling interest in the acquiree either at fair value or at the proportionate share of the acquiree’s identifiable net assets. Acquisition-related costs incurred are expensed and included in administrative expenses.

The subsequent acquisition of noncontrolling 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 noncontrolling interest, as measured at their fair value, over the net identifiable assets acquired and liabilities assumed.

m) Accrued liabilities

Accrued liabilities are recognized whenever (i) the Company has current obligations (legal or assumed) resulting from a past event, (ii) when it is probable the obligation will give rise to a future cash disbursement for its settlement and (iii) the amount of the obligation can be reasonably 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 future disbursements to settle the obligation. The discount rate applied is determined on a pre-tax basis and reflects current market conditions at the balance sheet date and, where appropriate, the risks specific to the liability. When discounting is used, an increase in the liability is recognized as a finance expense.

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

n) Labor obligations

The cost of pension, seniority premium and termination benefits (severance) are recognized periodically during the years of service of personnel, based on actuarial computations made by independent actuaries using the projected unit-credit method (see Note 10).

1. Description of the Business and Significant Accounting Policies (continued)

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

Beginning January 1, 2008, the Company adopted Mexican FRS D-3 Employee Benefits , which replaced Mexican accounting Bulletin D-3, Labor Obligations . As a result of the MFRS D-3 adoption, the transition liability for labor obligations and prior service costs at December 31, 2007 are being amortized over a maximum period of 5 years. Prior to December 31, 2007, such amounts were being amortized over the estimated average remaining working lifetime of Company employees (12 years) (see Note 10).

o) Employee profit sharing

Current-year and deferred employee profit sharing expense is presented as an ordinary expense in the income statement.

Beginning January 1, 2008, in connection with the adoption of Mexican FRS D-3, the Company recognizes deferred employee profit sharing using the asset and liability method. Under this method, deferred profit sharing is computed by applying the 10% rate to all temporary differences between the values of all assets and liabilities for financial and tax reporting purposes. The Company periodically evaluates the possibility of recovering deferred employee profit sharing assets and, if necessary, creates a valuation allowance for those assets that do not have a high probability of being realized (see Note 10).

p) 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 balance sheet 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 balance sheet date are charged or credited to results of operations.

See Note 11 for the Company’s consolidated foreign currency position at the end of each year and the exchange rates used to translate foreign currency denominated balances.

q) Comprehensive income

Comprehensive income consists of current year net income, the effect of translation of the financial statements of foreign entities, the changes in noncontrolling interest, the changes in the fair value of cash flow hedges and the effect of deferred taxes and deferred employee profit sharing related to these items.

1. Description of the Business and Significant Accounting Policies (continued)

r) Taxes on profits

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 tax

Deferred taxes on profits are recognized using the asset and liability method. Under this method, deferred taxes on profits 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 balance sheet date, or the enacted rate at the balance sheet 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 income statement are presented on a combined basis between their nature and function, in accordance with industry practice since such classification allows for an appropriate evaluation of gross profit and operating margin.

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

An analysis of the “Other expenses, net” caption for the years ended December 31, 2010 and 2009 is as follows:

P. 78,337

P. 1,349,680


1. Description of the Business and Significant Accounting Policies (continued)

t) Statement of cash flows

Effective January 1, 2008, the Company adopted Mexican FRS B-2 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 presents first income before taxes on profits, 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, 2010 and 2009 were prepared using the indirect method.

u) Earnings per share

Earnings per share are determined by dividing the controlling interest in net income by the weighted-average number of shares outstanding during the year. In determining the weighted-average number of shares outstanding during the year, shares repurchased by the Company have been excluded.

v) Concentration of risk

The main risks associated with the Company’s financial instruments are cash flow risk, liquidity risk, market risk and credit risk. The Company performs sensitivity analyses to measure potential losses in its operating results based on a theoretical increase of 100 basis points in interest rates and a 10% change in exchange rates. The Board of Directors approves the risk management policies that are proposed by the Company’s management.

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 located in different geographical areas.

1. Description of the Business and Significant Accounting Policies (continued)

The credit risk in accounts receivable is diversified, because the Company has a broad customer base that is geographically dispersed. 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.

w) Segments

Segment information is presented based on information used by the Company in its decision-making processes (see Note 16).

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

· Segment information only includes those companies that are directly involved in rendering local and long distance telephone services in Mexico.

· Local service includes: revenues from basic rent, measured service, installation charges, equipment sales and interconnection.

· Long distance service includes: revenues from basic services of domestic and international long distance services; it does not include revenues from rural and public telephony and data services.

· The services being disclosed include the corresponding attributes for interconnection, billing, collecting, co-location and leased lines.

· Interconnection with cellular operators includes revenues from calling party pays.

x) Reclassifications

Certain captions shown in the 2009 financial statements as originally issued have been reclassified for uniformity of presentation with the 2010 financial statements.

y) New accounting pronouncements

Following is a discussion of the new accounting pronouncements issued by the Mexican Financial Reporting Standards Research and Development Board ( Consejo Mexicano para la Investigación y Desarrollo de Normas de Información Financiera, A.C. or “CINIF”) that became effective on January 1, 2010 and that affected TELMEX’s accounting policies:

Mexican FRS C-1, Cash and Cash equivalents

In November 2009, the CINIF issued Mexican FRS C-1, which became effective for fiscal years beginning on or after January 1, 2010. Mexican FRS C-1 replaces Mexican accounting Bulletin C-1, Cash .. The main changes compared to Mexican accounting Bulletin are the presentation of restricted cash and the substitution of the term “short-term demand investments” with the new term “liquid demand investments”, which, among other characteristics, must be readily convertible to cash and have maturities of no more than three months.

1. Description of the Business and Significant Accounting Policies (concluded)

The adoption of this accounting standard must be made retrospectively. The adoption of the requirements of this standard had no effect on the Company’s financial position or on its results of operations.

Interpretation to Mexican FRS 19, Changes derived from the adoption of International Financial Reporting Standards

In August 2010, the CINIF issued Interpretation to Mexican FRS 19, which became effective for financial statements issued on or after September 30, 2010. This interpretation establishes the disclosures that must be made in the notes to the financial statements prepared under Mexican Financial Reporting Standards prior to the adoption of International Financial Reporting Standards.

The National Banking and Securities Commission (Comisión Nacional Bancaria y de Valores or “CNBV”) requires securities issuers registered with the National Securities Registry to prepare and disclose their financial information in conformity with International Financial Reporting Standards (IFRS) beginning on January 1, 2012, allowing early adoption. As a result of this requirement, the Company plans to adopt IFRS as the basis for preparing its financial information beginning on January 1, 2011.

Based on an analysis performed to identify the accounting effects upon adoption, the items which the Company has identified will have a significant impact on its financial statements are labor obligations, deferred taxes, stockholders’ equity and inflation effects. The Company is in the process of quantifying the impact on its financial statements.

A portion of the debt is also subject to early maturity or repurchase at the option of the holders in the event of a change in control of the Company, as so defined in each instrument. The definition of change in control varies from instrument to instrument; however, no change in control shall be considered to have occurred as long as Carso Global Telecom or its current stockholders continue to hold the majority of the Company’s voting shares.

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, 2010, the Company had cross currency swaps that hedge foreign currency denominated liabilities of P.43,091,161 (U.S.$3,487 million) (P.54,557,723 or U.S.$4,178 million in 2009). 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.$1,310 million and bank loans that mature from 2011 to 2018 of U.S.$2,177 million. These agreements allow TELMEX to fix the parity of such debt at a weighted-average exchange rate of P.10.7645 per U.S. dollar, as well as to set a fixed interest rate of 8.57% 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.

7. Debt (concluded)

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, 2010 was a net charge of P.2,108,445 (charge of P.5,682,263 in 2009).

Forwards dollar-peso

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 in 2009). For the year ended December 31, 2010, the Company recognized a net charge of P.97,295 (charge of P.520,733 in 2009) as part of the net exchange gain, due to changes in the fair value of these forwards.

Interest-rate swaps

At December 31, 2010, the Company had interest-rate swaps for an aggregate notional amount of P.16,649,250 (P.23,752,125 in 2009) to hedge the floating interest rate risk of its debt in Mexican pesos, fixing such rate at an average of 8.48%.

At December 31, 2010, the Company had no cross currency coupon swap contracts outstanding. At December 31, 2009 the Company had cross currency coupon swaps that covered interest payments flows of P.652,935 (U.S.$50 million).

For the year ended December 31, 2010, the Company recognized a net expense for these swaps in interest expense of P.1,687,679 (P.1,941,649 in 2009).

The ineffective portion of the cash flow hedges was a net expense of P.506,815 for the year ended December 31, 2010 (P.115,190 in 2009), 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.5,251,768 (U.S.$425 million). At December 31, 2010, 61% of the Company’s outstanding derivatives correspond to these types of agreements; however, no margin calls had been required at such date.

10. Labor Obligations (continued)

In 2010, the net actuarial loss of P.6,478,589 resulted from (i) the effect of a favorable actuarial variance of P.1,130,129 due to the behavior of the plan assets resulting from an increase in the value of 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.

In 2009, the net actuarial loss of P.5,829,259 resulted from (i) the effect of a favorable actuarial variance of P.4,371,737 due to the behavior of the plan assets resulting from an increase in the value of investments in shares of companies and in fixed-yield investments due to variances in reference rates, and (ii) an actuarial loss of P.10,200,996, 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.

c) Employee profit sharing

TELMEX is obligated to pay profit sharing to its employees in Mexico, in addition to their contractual compensation and benefits. For the years ended December 31, 2010 and 2009, employee profit sharing was based on 10% of the Company’s taxable income, excluding certain inflation effects and the re-expression of depreciation expense.

For the year ended December 31, 2010, the deferred employee profit sharing provision represented a credit to results of operations of P.518,403 (P.607,676 in 2009), which was recognized in the statement of income under the caption “Other expenses, net.”

At December 31, 2010 and 2009, the Company recognized deferred employee profit sharing on the following temporary items:

12. Commitments and Contingencies

Commitments

At December 31, 2010, TELMEX has non-cancelable commitments for the purchase of equipment of P.5,346,417 (P.3,372,975 in 2009), which include P.1,579,895 (P.977,637 in 2009) of non-cancelable commitments with related parties. Payments made under the related purchase agreements aggregated to P.2,832,019 in 2010 (P.2,858,996 in 2009).

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.

12. Commitments and Contingencies (continued)

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’s external lawyers who are handling this matter are of the opinion that although the Company’s arguments are well-founded, there is no guarantee that Teléfonos de México, S.A.B. de C.V. will actually 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. has substantial power and engages in monopolistic practices in certain markets.

Final resolutions in four of these investigations have been issued, in which COFECO has determined that Teléfonos de México, S.A.B. de C.V. has substantial power in the following areas: (i) termination of public commuted traffic; (ii) origination of public commuted traffic; (iii) local transit services; and (iv) leasing of lines or circuits. Teléfonos de México, S.A.B. de C.V. has expressed its disagreement with the proceedings, objected to the findings and submitted evidence against the resolutions.

In the four markets in question, COFECO has already confirmed its resolutions and Teléfonos de México, S.A.B. de C.V. filed the applicable motions for appeal, which COFECO denied. Teléfonos de México, S.A.B. de C.V. has filed relief ( amparo ) proceedings against the COFECO’s rejection of the motions for appeal, and the rulings on these relief proceedings are currently still pending. If the disputed resolutions are determined to be final, COFETEL, after completing the applicable procedure, may establish specific obligations for the Company regarding tariffs, quality of services and information in such markets, such as additional information and service quality disclosure requirements. 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 how long the Company will have to adopt the new regulations and whether it will actually be able to do so.

12. Commitments and Contingencies (continued)

In the four remaining investigations, COFECO is attempting to determine if TELMEX engaged in the alleged monopolistic practices in the following markets: (i) the broad-band internet market for domestic residential customers; and (ii) the local and national long-distance dedicated links wholesale leasing services market. These investigations are currently in the submission of evidence stage. For the inter-urban transport for commuted long-distance traffic services market and the fixed-network interconnection services market, COFECO has already issued and delivered Probable Fault Notices. Teléfonos de México, S.A.B. de C.V. promptly responded to these notices and contested the findings objecting to its considerations. There is no certainty as to the outcome of these investigations and notices and they may be unfavorable, which could result in regulations, restrictions or monetary fines being imposed on the Company.

Although the arguments of Teléfonos de México, S.A.B. de C.V. are considered well-founded, the Company’s external lawyers handling these cases do not believe that there is any certainty that the Company will obtain favorable rulings.

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, it was 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) In accordance with Mexican law, Teléfonos de México, S.A.B. de C.V. shall be severally liable for all of the obligations transferred to Telmex Internacional, S.A.B. de C.V. as a result of the split-up, for a three-year period, with respect to the terms of the split-up agreement approved by the shareholders of Teléfonos de México, S.A.B. de C.V. on December 21, 2007.This responsibility, however, does not apply to obligations with those creditors who have given their express consent relieving Teléfonos de México, S.A.B. de C.V. from these liabilities and approving the split-up.

12. Commitments and Contingencies (concluded)

e) On February 10, 2009, COFETEL published the Fundamental Technical Interconnection and Interoperability Plan in the Official Gazette .. Such plan could have a negative impact on Teléfonos de México, S.A.B. de C.V. and on the telecommunications sector in general, since it establishes additional obligations to concessionaries.

Teléfonos de México, S.A.B. de C.V. has legally challenged the plan through a number of available channels and has presented its evidence as to the illegality and unconstitutionality of the plan.

Although the arguments of Teléfonos de México, S.A.B. de C.V. are considered well-founded, the Company’s external lawyers handling these cases do not believe that there is any certainty that the Company will obtain favorable rulings.

f) In November 2010, the Communications Ministry submitted the guidelines issued by COFETEL for review by the Federal Commission for the Improvement of Regulations (COFEMER) in order for the latter to develop the cost models to be used to set the interconnection rates for providing interconnection services by the public telecommunications network concessionaires. After COFEMER has issued its Complete Final Ruling on such guidelines, they will be published by COFETEL in the Official Gazette and will become effective. This situation may have a negative effect on the Company’s revenues from interconnection services and on its results of operations.

In order for the resolutions adopted in extraordinary stockholders’ 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” stockholders will be required.

Under Mexican law, the stockholders of any Series of shares are also entitled to vote as one class on any proposal that could adversely affect the rights of the stockholders of that particular series and the Company’s stockholders (including the Series “L” stockholders), which individually or collectively represent 20% or more of all capital stock could judicially oppose any stockholders’ resolution with respect to those resolutions for which such stockholders have the right to vote. The determination of whether a matter requires the vote

14. Stockholders’ Equity (continued)

by the holders of Series “L” under such basis would initially be made by the board of directors or by any other party that calls a stockholders’ meeting to decide on the resolution. A negative decision would be subject to judicial challenge by any affected stockholder, 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 stockholders’ meeting held on March 3, 2009, the stockholders 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 2010, the Company acquired 33.9 million Series “L” shares for P.339,746 and 6,906 Series “A” shares for P.76.

In 2009, the Company acquired 361.2 million Series “L” shares for P.4,073,625 and 1.9 million Series “A” shares for P.21,695.

At December 31, 2010 and 2009, the Company had 14,074 million (14,032 million Series “L” and 42 million Series “A”) and 14,040 million (13,998 million Series “L” and 42 million Series “A”) treasury shares, respectively.

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

d) At December 31, 2010, “Accumulated other comprehensive income items” include P.211,741 for the effective portion of the fair value of swaps designated as cash flow hedges and P.174,368 for the effect of translation of foreign entities, net of deferred taxes (P.748,675 and P.134,550 in 2009, respectively).

e) At a regular meeting held onApril29, 2010, the stockholders 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 December2010 andin 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 28, 2009.

14. Stockholders’ Equity (concluded)

At a regular meeting held onApril28, 2009, the stockholders agreed to declare a cash dividend of P.0.46 per outstanding share, to be paid in four installments of P.0.1150 each in June, September and December2009 andin March 2010. In March 2009, the Company paid the fourth installment of P.0.10 per outstanding share, which was authorized at the regular meeting held on April 25, 2008. At a regular meeting held on December 1, 2009, the stockholders agreed to declare an extraordinary cash dividend of P.0.40 per outstanding share, paid in a single payment beginning on December 17, 2009.

The cash dividends paid in 2010 and 2009 were P.8,736,965 and P.15,093,082, respectively.

15. 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.

Beginning 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. As established under the Law, certain FRBT credits also may be deducted from the FRBT payable. Under the Law’s transitory provisions, the FRBT rate is 16.5% in 2008, 17% in 2009 and 17.5% in 2010 and succeeding years.

When the FRBT base is negative because deductions exceed taxable income, there is no FRBT payable. The amount of the negative base multiplied by the FRBT rate results in a FRBT credit, which in 2008 and 2009 could be applied against income tax for the same year or, if applicable, may be applied against FRBT payable in the next ten years.

FRBT creditable concepts result mainly from the negative FRBT base to be amortized, salary and social security contribution credits, and credits arising from the deduction of certain assets, such as inventories and fixed assets, during the transition period as of the date on which the FRBT became effective.

FRBT is payable only to the extent it exceeds income tax for the same period. To determine FRBT payable, income tax paid in a given period is first subtracted from the FRBT of the same period.

15. Income Tax and Flat-Rate Business Tax (continued)

For the years ended December 31, 2010 and 2009, 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:

16. Segments


TELMEX primarily operates in two segments: local and long distance telephone service. The local telephone service segment corresponds principally to local fixed-line wired service, including interconnection service. The long distance service segment includes domestic and international service. Other segments include long distance calls made from public and rural telephones, data services and other services. Additional information related to the Company’s operations is provided in Note 1. The following summary shows the most important segment information, which has been prepared on a consistent basis:

16. Segments (concluded)

Inter-segmental transactions are reported based on terms offered to third parties. Employee profit sharing, other expenses, financing cost, equity interest in net income of affiliates and the income tax provision are not allocated to each segment, because they are handled at the corporate level.

Segment assets include plant, property and equipment (excluding accumulated depreciation), construction in progress and advances to equipment suppliers, and inventories for operation of the telephone plant.

17. Subsequent Event

On March 8, 2011, TELMEX announced that its Board of Directors approved a corporate restructuring to segregate the business into two companies, one of which will be named TELMEX Social that will provide telecommunications and interconnection services in low income and rural areas where competitors do not invest, and the other company will provide these services in the other areas of Mexico. With this restructuring, the assets, liabilities and equity would be divided accordingly, and the labor rights of the employees of both companies will be respected.

The restructuring is subject, if needed, to the approval of the Communications Ministry ( Secretaría de Comunicaciones y Transportes , or SCT), as well as the authorization and confirmation of the rest of the corresponding authorities and governmental entities, in addition to the authorizations required under the Mexican Corporations Act.

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 balance sheet 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 balance sheet date are charged or credited to results of operations.


Translation of financial statements of foreign subsidiary and affiliate


The financial statements of the foreign subsidiary and affiliate are either consolidated or accounted for based on the equity method, as the case may be, once the financial statements have been adjusted to conform to Mexican Financial Reporting Standards in the corresponding local currency, and are then translated to the reporting currency. All the assets and liabilities of our foreign subsidiary and affiliate are translated to Mexican pesos at the prevailing exchange rate at the end of the period. Stockholders’ equity accounts are translated at the prevailing exchange rate at the time capital contributions were made and earnings were generated. Revenues, costs and expenses are translated at the historical exchange rate. Translation differences are recorded in stockholders’ equity in the line item “Effect of translation of foreign entities” under “Accumulated other comprehensive income items.”

Quarterly Report of Derivative Financial Instruments


I. Executive Summary


As of December 31, 2010, Teléfonos de México, S.A.B. de C.V. (“Telmex” or the “Company”) had cross currency swap agreements in the equivalent of U.S.$3,487 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.$1,310 million and loans with maturities from 2011 to 2018 for a total amount of U.S.$ 2,177 million. These hedges allowed us to fix the exchange rate of our debt on a weighted average exchange rate of P.10.7645 Mexican pesos per U.S. dollar and an average interest rate of the 28-day Mexican interbank equilibrium interest rate (“TIIE”) less a specified margin, as well as to set a fixed rate of 8.57% for the bond maturing in 2015.


At the end of the fourth quarter, the Company had forward contracts for U.S.$40 million at a exchange rate of P.12.9114 Mexican pesos per US dollar.


At December 31, 2010, the Company had interest rate swaps in Mexican pesos for P.16,649 million to hedge the floating rate risk in local currency, fixing it at an average of 8.48%.


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 establish 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:


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

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

(c) 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 Subdirector of Budget and Financial Evaluation 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. During 2010 and 2009, 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, 2010, our cross currency swaps position is deemed to be highly effective, with an effectiveness factor of approximately 96.1%


Also, P.11,649 million of our interest rate swaps are deemed to be highly effective, with an effectiveness factor of approximately 95.6%, while the remaining P.5,000 million were considered ineffective.



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.


During 2010, the change in the fair value of the cross currency swaps that offset the exchange gain of the foreign-currency denominated debt was a net charge of P.2,108 million (net charge of P.5,682 million in 2009).


For the year ended December 31, 2010, the Company recognized a net charge of P.97 million (charge of P.521 millionin 2009) as part of the net exchange gain, due to changes in the fair value of short term foreign currency forwards.


Additionally, in 2010 the Company recognized in interest expense a net expense for interest rate swaps of P.1,688 million (net expense of P.1,942 million in 2009).


In 2010, the ineffective portion of the cash flow hedges was a net expense of P.507 million (net expense of P.115 million in 2009), recognized in interest expense.


During the fourth quarter, 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, 64% 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 U.S.$425 million.

(1) These swaps hedge the debt position in U.S. 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.

III. Sensitivity Analysis

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 underlying asset (interest rate) of 100 basis points, would result in a charge in the Company’s income statements of P.373 million.
