SELECTED FINANCIAL DATA

The following tables present a summary of our consolidated financial information for each of the periods indicated. This information should be read in conjunction with, and is qualified in its entirety by reference to, our audited consolidated financial statements referred to in Item 18 hereof and included elsewhere in this document, including the notes thereto. Our audited consolidated financial statements are prepared in accordance with Mexican Financial Reporting Standards, or MFRS, which differ in certain significant respects from accounting principles generally accepted in the United States of America, or U.S. GAAP. A reconciliation to U.S. GAAP of our net income and total stockholders’ equity is also provided in the following tables. Note 24 to our audited consolidated financial statements provides a description of the principal differences between MFRS and U.S. GAAP as they relate to our business.

Through 2007, MFRS provided for the recognition of certain effects of inflation by restating non-monetary assets and non-monetary liabilities using the National Consumer Price Index (Índice Nacional de Precios al Consumidor or NCPI), restating the components of stockholders’ equity using the NCPI and recording gains or losses in purchasing power from holding monetary assets or liabilities. MFRS required the restatement of all financial statements to constant Mexican pesos as of the date of the most recent balance sheet presented. Accordingly, our audited consolidated financial statements and all other financial information contained herein are presented in constant pesos with purchasing power as of December 31, 2007, unless otherwise noted.

Procedures used at the close of 2007 to recognize the effects of inflation in terms of purchasing power were as follows:

Balance sheets:

• Non-monetary assets are restated using a factor derived from the NCPI from the date of acquisition. Depreciation and amortization of restated asset values are calculated using the straight-line method based on the estimated economic useful life of each asset.

• Common stock, legal reserve, retained earnings and the cumulative initial effect of deferred income taxes are restated using a factor derived from the NCPI, cumulative from the date of contribution or generation.

Statements of income:

• Revenues and expenses that are associated with monetary items (including trade receivables, cash and liabilities) are restated from the month in which they arise through period end, based on factors derived from the NCPI.

• Other expenses related to the consumption of non-monetary items are restated when incurred based on the restated value of the corresponding asset from the date of consumption of the non-monetary asset through the end of the period, using factors derived from the NCPI.

• Monetary position result, which represents the erosion of the purchasing power of monetary items caused by inflation, is determined by applying to net monetary assets or liabilities, at the beginning of each month, the factor of inflation derived from the NCPI and is restated through period-end with the corresponding factor. Losses result from maintaining a net monetary asset position.

Other statements:

• The consolidated statements of changes in stockholders’ equity and changes in financial position present the changes in constant Mexican pesos, based on the financial position at prior year-end, restated to Mexican pesos as of the most recent year-end.

Recent changes affecting inflation accounting:

MFRS has changed for periods beginning in 2008, and the inflation accounting methods summarized above will no longer apply unless the economic environment in Mexico qualifies as “inflationary” for purposes of MFRS. The environment is inflationary if the cumulative inflation rate equals or exceeds an aggregate of 26% over three years (equivalent to an average of 8% in each year). Because of the relatively low level of Mexican inflation in recent years, and based on current forecasts, we do not expect the Mexican economic environment to qualify as inflationary in 2008 or 2009, but that could change depending on actual economic performance.

As a result, we expect to present financial statements without inflation accounting beginning in 2008.

This Form 20-F contains translations of certain peso amounts into U.S. dollars at specified rates solely for the convenience of the reader. These translations should not be construed as representations that the peso amounts actually represent such U.S. dollar amounts or could be converted into U.S. dollars at the rates indicated. Unless otherwise indicated, U.S. dollar amounts have been translated from Mexican pesos at an exchange rate of Ps. 10.9169 per U.S. dollar, the noon buying rate published by the Federal Reserve Bank of New York for transfers in Mexican pesos on December 31, 2007.

References in this Form 20-F to “dollars,” “U.S. dollars” or “U.S.$ “ are to the lawful currency of the United States of America. References in this Form 20-F to “pesos,” “Mexican pesos” or “Ps.” are to the lawful currency of Mexico. We publish our audited consolidated financial statements in pesos.

This Form 20-F contains references to “workload units,” which are units measuring an airport’s passenger traffic volume and cargo volume. A workload unit currently is equivalent to one terminal passenger or 100 kilograms of cargo. When we refer to “terminal passengers” we mean the sum of all arriving and departing passengers on commercial and general aviation flights, other than transit passengers. “Transit passengers”, or “through passengers,” are those who are generally not required to change aircraft while on a multiple-stop itinerary, who generally do not disembark their aircraft to enter the terminal building. When we refer to “total passengers” we mean the sum of terminal passengers and transit passengers. When we refer to “commercial aviation passengers,” we mean the sum of terminal and transit passengers, excluding general aviation passengers, such as those on private non-commercial aircraft. Country-wide data for Mexico presented herein are based on commercial aviation passengers, but we generally measure our operations based on terminal passengers.

This Form 20-F contains references to “air traffic movements” which represent the sum of all aircraft arrivals and departures of any kind at an airport.

The summary financial and other information set forth below reflects our financial condition, results of operations and certain operating data for the periods indicated.

(1) All peso amounts are expressed in constant pesos with purchasing power as of December 31, 2007. Per-share peso amounts are expressed in pesos (not thousands of pesos). Operating data are expressed in the units indicated.

(2) Translated into dollars at the rate of Ps. 10.9169 per U.S. dollar, the noon buying rate published by the Federal Reserve Bank of New York for transfers in Mexican pesos on December 31, 2007. The U.S. dollar information should not be construed to imply that the peso amounts represent, or could have been or could be converted into U.S. dollars at such rate or at any other rate. Per-share dollar amounts are expressed in dollars (not thousands of dollars). Operating data are expressed in the units indicated.

(3) Revenues from aeronautical services principally consist of a fee for each departing passenger, aircraft landing fees based on an aircraft’s weight and arrival time, an aircraft parking fee, a fee for the transport of passengers from an aircraft to a terminal building and a security charge for each departing passenger, and other sources of revenues subject to regulation under our maximum rates. See Item 4 herein for a description of our regulatory framework, including our maximum rates.

(4) Revenues from non-aeronautical services consist of revenues not subject to regulation under our maximum rates, which are primarily revenues from car parking charges, leasing of commercial space to tenants, advertisers, certain ground transportation providers and other miscellaneous sources of revenues. Pursuant to our operating concessions and Mexico’s Airport Law (Ley de Aeropuertos) and the regulations thereunder, parking services are currently excluded from regulated services under our maximum rates, although the Ministry of Communications and Transportation (Secretaría de Comunicaciones y Transportes) could decide to regulate such rates.

(5) Beginning January 1, 2000, we began paying Aeropuertos Mexicanos del Pacífico S.A. de C.V. (“AMP”) a technical assistance fee under the technical assistance agreement entered into in connection with AMP’s purchase of our Series BB shares. This fee is described in Item 7 hereof.

(6) As of November 1, 1998, each of our subsidiary concession holders has been required to pay a concession tax to the Mexican government under the Mexican Federal Duties Law (Ley Federal de Derechos) for the use of public domain assets pursuant to the terms of its concession. The concession tax is currently 5% of each concession holder’s gross annual revenues.

(7) Reflects depreciation of fixed assets.

(8) Reflects amortization of concessions, rights to use airport facilities, recovered long-term leases and parking lots.

(9) Represents the gain that resulted from the application of MFRS Bulletin C-10 governing derivative financial instruments and other hedging operations. See Note 3.l to our audited consolidated financial statements.

EXCHANGE RATES

The following table sets forth, for the periods indicated, the high, low, average and period-end, free-market exchange rate between the peso and the U.S. dollar, expressed in pesos per U.S. dollar. The average annual rates presented in the following table were calculated using the average of the exchange rates on the last day of each month during the relevant period. The data provided in this table is based on noon buying rates published by the Federal Reserve Bank of New York for transfers in Mexican pesos. We have not restated the rates in constant currency units. All amounts are stated in pesos. We make no representation that the Mexican peso amounts referred to in this annual report could have been or could be converted into U.S. dollars at any particular rate or at all.

In recent decades, the Mexican Central Bank (Banco de México) has consistently made foreign currency available to Mexican private-sector entities (such as us) to meet their foreign currency obligations. Nevertheless, in the event of shortages of foreign currency, there can be no assurance that foreign currency would continue to be available to private-sector companies or that foreign currency needed by us to service foreign currency obligations or to import goods could be purchased in the open market without substantial additional cost.

Fluctuations in the exchange rate between the peso and the U.S. dollar affect the U.S. dollar value of securities traded on the Mexican Stock Exchange (Bolsa Mexicana de Valores S.A. de C.V.), and, as a result, affect the market price of our ADSs. Such fluctuations may also affect the U.S. dollar conversion by The Bank of New York, the depositary for our ADSs, of any cash dividends paid by us in pesos.

RISK FACTORS

Risks Related to Our Operations

Our revenues are highly dependent on levels of passenger and cargo traffic volumes and air traffic, which depend in part on factors beyond our control.

Our revenues are closely linked to passenger and cargo traffic volumes and the number of air traffic movements at our airports. These factors directly determine our revenues from aeronautical services and indirectly determine our revenues from non-aeronautical services. Passenger and cargo traffic volumes and air traffic movements depend in part on many factors beyond our control, including economic conditions in Mexico and the United States, the political situation in Mexico and elsewhere in the world, the attractiveness of our airports relative to that of other competing airports, fluctuations in petroleum prices (which can have a negative impact on traffic as a result of fuel surcharges or other measures adopted by airlines in response to increased fuel costs) and changes in regulatory policies applicable to the aviation industry. Any decreases in air traffic to or from our airports as a result of factors such as these could adversely affect our business, results of operations, prospects and financial condition.

Our business could be adversely affected by a downturn in the U.S. economy.

In 2007, 95.8% of the international passengers served by our airports arrived or departed on flights originating in or departing to the United States. Thus, our business is dependent on the condition of the U.S. economy, and is particularly influenced by trends in the United States relating to leisure travel, consumer spending and international tourism. Events and conditions affecting the U.S. economy may adversely affect our business, results of operations, prospects and financial condition. The U.S. economy has recently experienced and continues to experience an economic slowdown that may negatively affect our results of operations. If this slowdown becomes a prolonged economic crisis, it will likely have a material adverse effect on our results of operations.

The events of September 11, 2001 resulted in a significant decline in passenger traffic worldwide and future terrorist attacks could result in similar declines.

The terrorist attacks on the United States on September 11, 2001 had a severe adverse impact on the air travel industry, particularly on U.S. carriers and on carriers operating international services to and from the United States. Airline traffic in the United States fell precipitously after the attacks. Our terminal passenger volumes declined 1.4% in 2001 and an additional 5.3% in 2002 (in each case as compared to the prior year). Any future terrorist attacks, whether or not involving aircraft, will likely adversely affect our business, results of operations, prospects and financial condition.

7

Security enhancements following the events of September 11, 2001 have resulted in increased costs, and future security enhancements could further increase our costs and reduce our operating margins.

The air travel business is susceptible to, and has experienced increased costs resulting from enhanced security and higher insurance and fuel costs. Following the events of September 11, 2001, we reinforced security at our airports. While enhanced security at our airports has not resulted in a significant increase in our operating costs to date, we may be required to adopt additional security measures in the future. In addition, our general liability insurance premiums for 2002 and 2003 increased substantially relative to our 2001 premiums and may continue to rise in the future. In 2004, our aggregate insurance cost was more than double our aggregate insurance cost for 2001. Since August 1, 2003, we have carried a Ps. 500 million insurance policy covering damages to our property resulting from terrorist acts. Since January 2003, we have carried an insurance policy covering personal and property damages to third parties resulting from terrorist acts. The coverage provided by this policy was initially U.S.$ 10 million, but was increased to U.S.$ 150 million in 2007. Because our insurance policies do not cover all losses and liabilities resulting from war or from terrorism, we could incur significant costs if we were to be directly affected by events of this nature. Any such increase in our operating costs would have an adverse effect on our results of operations.

The users of airports, principally airlines, have been subject to increased costs since the events of September 11, 2001. Airlines have been required to adopt additional security measures and may be required to comply with more rigorous security rules or guidelines in the future. Premiums for aviation insurance have increased substantially and could escalate further. While governments in other countries have agreed to indemnify airlines for liabilities they might incur resulting from terrorist attacks, the Mexican government has given no indication of any intention to do so. In addition, fuel prices and supplies, which constitute a significant cost for airlines using our airports, may be subject to increases resulting from any future terrorist attacks, a general increase in international hostilities or a reduction in output of fuel, voluntary or otherwise, by oil-producing countries. Such increases in airlines’ costs have in the past resulted in higher airline ticket prices and decreased demand for air travel generally, thereby having an adverse effect on our revenues and results of operations. In addition, because a substantial majority of our international flights involve travel to the United States, we may be required to comply with security directives of the U.S. Federal Aviation Authority, in addition to the directives of Mexican aviation authorities.

In 2005, the Mexican government issued a policy letter (carta de política) calling for all checked baggage on international commercial flights beginning in January 2006, and on domestic commercial flights beginning in July 2006, to undergo a new comprehensive screening process. Because of uncertainty over the policy letter’s implementation, the new screening process has been delayed. In particular, the policy letter does not specify which parties should bear responsibility for the new screening process. Although the Mexican Airport Law specifies that airlines bear the responsibility for baggage screening, the fact that the policy letter is silent as to responsibility has caused some of our airline customers to contend that the policy letter’s intent is for airport concessionaires, such as us, to bear responsibility for the new screening process. In addition, certain questions have been raised regarding the constitutionality of the new screening process. The Mexican Bureau of Civil Aviation is expected to issue regulations

8

implementing the policy letter, but these may not address the questions of responsibility and constitutionality that have been raised. We maintain that the new policy will not be implemented at our airports until we enter into a written agreement with our airline customers regarding the allocation of cost and responsibility. The new process is expected to require the installation of new screening equipment and that baggage be checked manually if the equipment signals the potential presence of prohibited items. If we are required to purchase, install and operate the new screening equipment, this could increase our exposure to liability. We could be required to undertake significant capital expenditures to purchase the equipment and incur ongoing expenses to maintain the equipment we have purchased, which could restrict our liquidity and adversely affect our results of operations.

International events could have a negative impact on international air travel.

Historically, a substantial majority of our revenues has been derived from aeronautical services, and our principal source of aeronautical services revenues is passenger charges. Passenger charges are payable for each passenger (other than diplomats, infants and transfer and transit passengers) departing from the airport terminals we operate, and are collected by the airlines and paid to us. In 2005, 2006 and 2007, passenger charges represented 65.4%, 65.1%, and 67.2%, respectively, of our total revenues. Events such as the war in Iraq and public health crises such as the Severe Acute Respiratory Syndrome, or SARS, crisis in 2003 have negatively affected the frequency and pattern of air travel worldwide. Because our revenues are largely dependent on the level of passenger traffic in our airports, any general increase of hostilities relating to reprisals against terrorist organizations, further conflict in the Middle East, outbreaks of health epidemics such as SARS or other events of general international concern (and any related economic impact of such events) could result in decreased passenger traffic and increased costs to the air travel industry and, as a result, could cause a material adverse effect on our business, results of operations, prospects and financial condition.

Our revenues and profitability may not increase if we fail in our business strategy.

Our ability to increase our revenues and profitability depends in part on our business strategy, which consists of setting prices in order to be as close as possible to our regulatory maximum rates for any given year, reducing operating costs, increasing passenger and cargo traffic at our airports and increasing revenues from commercial activities.

Our ability to increase our commercial revenues is significantly dependent, among other factors, upon increasing passenger traffic at our airports and our ability to renegotiate rental agreements with our tenants to provide for contractual terms more favorable to us. Our ability to increase revenues from commercial activities is also dependent on our ability to continue the remodeling and modernization of the commercial areas we operate within our airports. We cannot assure you that we will be successful in implementing our strategy of increasing our passenger traffic or our revenues from commercial activities. The passenger traffic volume in our airports depends on factors beyond our control, such as the attractiveness of the commercial, industrial and tourist centers that the airports serve. Accordingly, there can be no assurance that the passenger traffic volume in our airports will increase or that our profitability will increase.

A claim against us by a construction company relating to work at the Guadalajara airport could have a negative resolution.

In August 2005, we entered into a construction contract with Grupo de Ingeniería Universal, S.A. de C.V., or GIUSA, for the development of a new segment of the Guadalajara International Airport’s apron. GIUSA delayed the project and we therefore executed the performance bond posted by GIUSA in an amount equal to 20% of the total contract value. However, we were not able to obtain such execution because, in September 2006, GIUSA initiated legal proceedings against us, claiming breach of contract by us and seeking the full contract amount and additional damages, together totaling Ps. 43 million. During 2007, we obtained a favorable sentence in first instance, which was appealed by GIUSA. As of the date of our consolidated financial statements, the resolution of this appeal is still pending.

Competition from other tourist destinations could adversely affect our business.

The principal factor affecting our results of operations and business is the number of passengers using our airports. The number of passengers using our airports (particularly our Los Cabos International Airport and our Puerto Vallarta International Airport) may vary as a result of factors beyond our control, including the level of tourism in Mexico. In addition, our passenger traffic volume may be adversely affected by the attractiveness, affordability and accessibility of competing tourist destinations in Mexico, such as Cancún and Acapulco, or elsewhere, such as Puerto Rico, Florida, Cuba, Jamaica, the Dominican Republic and other Caribbean islands and destinations in Central America. The attractiveness of the destinations we serve is also likely to be affected by perceptions of travelers as to the safety and political and social stability of Mexico. There can be no assurance that tourism levels, and therefore the number of passengers using our airports, in the future will match or exceed current levels, the failure of which could directly and indirectly affect our revenues from aeronautical and non-aeronautical services, respectively.

Our business is highly dependent upon revenues from four of our airports and could be adversely impacted by any condition affecting those airports.

In 2007, approximately 78.3% of our revenues were generated from four of our 12 airports. The following table lists the percentage of total revenues generated at our airports in that year:

Airport	For year ended December 31, 2007
Guadalajara International Airport	33.4	%
Tijuana International Airport	13.7
Puerto Vallarta International Airport	15.2
Los Cabos International Airport	16.0
Eight other airports	21.7
Total	100.0	%

10

As a result of the substantial contribution to our revenues from these four airports, any event or condition affecting these airports could have a material adverse effect on our business, results of operations, prospects and financial condition.

If a change in relations with our labor force should occur, such a change could have an adverse impact on our results of operations.

Although we currently believe we maintain good relations with our labor force, if any conflicts with our employees were to arise in the future, including with our unionized employees (which accounted for 52.5% of our total employees at December 31, 2007), resulting events such as strikes or other disruptions that could arise with respect to our workforce could have a negative impact on our results of operations.

The loss of one or more of our key customers could result in a loss of a significant amount of our revenues.

Consorcio Aeroméxico, S.A. de C.V., or Consorcio Aeroméxico (controlled by the Mexican government until October 2007), is a holding company that owns Aeroméxico, one of the principal domestic airlines operating at our airports. Of the total revenues generated at our airports in 2007, Aeroméxico and Aeroméxico Connect (formerly Aerolitoral and also owned by Consorcio Aeroméxico) together accounted for 15.31%, while Grupo Mexicana (composed of Mexicana de Aviación and Click Mexicana), which until December 2005 was owned by the government, and which is now owned by Grupo Posadas S.A. de C.V., represented 12.01%. None of our contracts with our airline customers obligate them to continue providing service to our airports, and we can offer no assurance that, if any of our key customers reduced their use of our airports, competing airlines would add flights to their schedules to replace any flights no longer handled by our principal airline customers. During 2007, Banamex acquired both Aeroméxico and Aeroméxico Connect. We can offer no assurance that these airlines will operate independently in the future or that they will continue to use any of our airports. Decisions made by Banamex with respect to its ownership interest in its airlines could also affect the operations and business of Aeroméxico and Aeroméxico Connect and, in turn, have a material adverse effect on our results of operations. Our business and results of operations could be adversely affected if we do not continue to generate comparable levels of our revenues from our key customers.

In 2007, the passenger charges that we invoiced to airlines were generally collected, on a weighted average basis, approximately 78 to 88 days following the invoice delivery date. The actual term for payment generally is dependent upon interest rates on short-term Mexican treasury bills, orCetes, with longer payment periods during periods of lower interest rates (within a defined range). Our revenues from passenger charges are not secured by a bond or any other collateral. Thus, in the event of insolvency of any airline, as occurred in 2003 in the case of Líneas Aéreas Allegro S.A. de C.V., we would not be assured of collecting any amounts invoiced to that airline in respect of passenger charges, which could negatively affect our cash flows from operations.

11

The principal domestic airlines operating at our airports have in the past refused to pay certain increases in our specific prices for aeronautical services and could refuse to pay additional increases in the future.

From 2000 to mid-2003, the principal domestic airlines operating at our 12 airports—Aeroméxico, Mexicana, Aeromar and Aeroméxico Connect—refused to pay certain increases in the specific prices we charge for aeronautical services. On August 31, 2003 (the date on which the balance reached its peak), the amount of invoiced fees subject to dispute was Ps. 47.0 million. As part of this dispute, these airlines brought proceedings challenging the privatization of the Mexican airport sector and the methodology for calculating the maximum rate system applicable under the privatization of all of the airport groups in Mexico.

On July 15, 2003, we entered into an agreement with the National Air Transportation Chamber of Commerce (Cámara Nacional de Aerotransportes) and the Ministry of Communications and Transportation pursuant to which we resolved existing disputes with our principal airline customers and established specific prices for aeronautical services applicable to those airlines for 2003 and 2004 and a methodology for retroactively applying those prices from 2000, since these airlines had refused to pay certain of our charges since that year. In March 2005, we entered into a renewal agreement with the National Air Transportation Chamber of Commerce for 2005 and 2006. The National Air Transportation Chamber of Commerce agreed to cause our principal airline customers to enter into (a) contracts governing charges for aeronautical services, (b) lease contracts for property used by the airlines and (c) contracts governing collection of passenger charges. As of December 31, 2005, these airlines had entered into agreements with us such that proceedings against us were either resolved or dismissed and no fees remained subject to further dispute. These agreements represented (a) virtually all of the relevant contracts governing the collection of passenger charges, (b) a substantial majority of the agreements for the leasing of space in our terminals and (c) a substantial majority of the contracts governing our aeronautical services, in each case in terms of the total number agreements to be entered into. In December 2006, we entered into a renewal agreement with the National Air Transportation Chamber of Commerce for 2007, 2008 and 2009, covering the same aspects as the prior agreement as well as incorporating an increase in passenger charges. This renewal agreement is more focused on the support and development of, and increased frequencies on, new routes.

Because these airlines contribute a majority of our revenues, should the airlines refuse to make payment pursuant to the agreements described above, or should they refuse to pay increases in our charges for aeronautical services in future years, our results of operations could be adversely impacted.

The operations of our airports may be disrupted due to the actions of third parties, which are beyond our control.

As is the case with most airports, the operation of our airports is largely dependent on the services of third parties, such as air traffic control authorities and airlines. We are also dependent upon the Mexican government or entities of the government for provision of services, such as electricity, supply of fuel to aircraft, air traffic control and immigration and customs services for our international passengers. We are not responsible for and cannot control the

12

services provided by these parties. Any disruption in, or adverse consequence resulting from, their services, including a work stoppage or other similar event, may have a material adverse effect on the operation of our airports and on our results of operations.

In addition, we are dependent on third-party providers of certain complementary services such as catering and baggage handling. If these service providers were to halt operations at any of our airports, we would be required to seek a new service provider or provide services ourselves, either of which would likely result in increased capital expenditures or costs and have an adverse impact on our cash generation and results of operations.

Actions by the former holders of land comprising Tijuana International Airport may limit our ability to expand the airport and may disrupt its operations.

A portion of the land comprising Tijuana International Airport was expropriated by the Mexican government in 1970 pursuant to its power of eminent domain. Prior to its expropriation, the land had been held by a group of individuals through a system of communal ownership of rural land known as anejido. The formerejido participants have asserted claims against the Mexican government challenging the 1970 expropriation decree. Our Tijuana airport subsidiary is a party to the proceedings, but only as an interested third party. A judgment in favor of the formerejido participants could materially disrupt the airport’s current operations. The terms of our concession require the Mexican government to provide restitution to us for any loss of our use of the land subject to our concessions.

Certain of the formerejido participants are currently occupying portions of the real property on which we operate Tijuana International Airport that are not currently essential to the airport’s operations. Although these persons are not currently interfering with the airport’s operations, their presence could limit our ability to expand the airport into the areas they currently occupy. In addition, there can be no assurance that the formerejido participants will not seek to disrupt the airport’s operations if their legal claims against the Mexican government are not resolved to their satisfaction.

The actions of squatters on certain portions of the land on which our Guadalajara International Airport operates could disrupt operations and security at that airport.

The Mexican government owns the land on which the Guadalajara International Airport operates and has granted us the right to use that land for the purpose of operating the airport pursuant to our concession. Currently, there are squatters residing on or claiming rights to a portion of the property, at least one of whom has attempted to subdivide and sell off certain portions of the property. As owner of the property, the Mexican government must initiate any actions directed at removing these persons from the property. We are reviewing the actions these persons have taken and are cooperating with the Mexican government to ensure that the actions of these squatters do not adversely affect the operations of the Guadalajara International Airport. However, if the Mexican government or we are unable to successfully remove these persons from the property, their presence could have an adverse impact on our operations and security at the airport and could restrict our ability to expand our operations at the airport.

13

High incidences of crime in Mexico, and drug trafficking in particular, could adversely affect our business.

A recent Travel Alert issued by the U.S. Department of State (Bureau of Consular Affairs) on April 14, 2008 provides information for U.S. citizens on security issues in Mexico. According to such report, violent criminal activity fueled by a war between criminal organizations struggling for control of the lucrative narcotics trade continues along the U.S.-Mexico border. Although attacks are aimed primarily at members of drug trafficking organizations and Mexican police forces, foreign visitors and residents, including U.S. citizens, have been among the victims of homicides and kidnappings in the border region. Violence by criminal elements affects many parts of the country, both urban and rural, including border areas. Though there is no evidence that U.S. citizens are specifically targeted, Mexican and foreign bystanders have been injured or killed in some violent attacks, demonstrating the heightened risk in public places. Higher incidences of crime throughout Mexico, and drug trafficking in particular, could have an adverse affect on our business as it may decrease the passenger traffic directed to Mexico from abroad. In addition, our operations could be affected to the extent that it is necessary for us to increase security surveillance and other measures in our airports to combat crime, including drug trafficking.

Natural disasters could adversely affect our business.

From time to time, the Pacific and central regions of Mexico experience torrential rains and hurricanes (particularly during the months of July through September), as well as earthquakes. The most recent natural events that affected our airports were two hurricanes in August and September of 2003 that resulted in temporary closures and property damages at our Los Cabos International Airport and our La Paz International Airport. In addition, the Manzanillo International Airport experienced an earthquake in 2003, which caused significant damage to the airport and required the airport to be closed for several hours. Natural disasters may impede operations, damage infrastructure necessary to our operations or adversely affect the destinations served by our airports. In 2006 and 2007, Los Cabos International Airport and La Paz International Airport were closed for several hours as a result of Hurricanes John, Lane and Henriette but experienced no significant damages. Any of these events could reduce our passenger traffic volume. The occurrence of natural disasters in the destinations we serve could adversely affect our business, results of operations, prospects and financial condition. We have insured the physical facilities at our airports against damage caused by natural disasters, accidents or other similar events, but do not have insurance covering losses due to resulting business interruption. Moreover, should losses occur, there can be no assurance that losses caused by damages to the physical facilities would not exceed the pre-established limits on any of our insurance policies.

Risks Related to the Regulation of Our Business

We cannot predict how the regulations governing our business will be applied.

Many of the laws, regulations and instruments that regulate our business were adopted or became effective in 1999, and there is only a limited history that would allow us to predict the impact of these legal requirements on our future operations. In addition, although Mexican law establishes ranges of sanctions that might be imposed should we fail to comply with the terms of one of our concessions, the Mexican Airport Law (Ley de Aeropuertos) and its regulations or other applicable law, we cannot predict the sanctions that are likely to be assessed for a given violation within these ranges. We cannot assure you that we will not encounter difficulties in complying with these laws, regulations and instruments.

14

Moreover, when determining our maximum rates for the next five-year period (from 2010 to 2014), the Ministry of Communications and Transportations may be pressured significantly by different entities (such as, for example, the Mexican Competition Commission and the carriers operating at our airports) to try to impose rates that reduce our profitability. Therefore, there can be no assurance that the laws and regulations governing our business, including the rate-setting process and the Mexican Airport Law, will not change in the future or be applied or interpreted in a way that could have a material adverse effect on our results of operations.

We provide a public service regulated by the Mexican government and our flexibility in managing our aeronautical activities is limited by the regulatory environment in which we operate.

Our aeronautical fees charged to airlines and passengers are regulated, like those of most airports in other countries. In 2005, 2006 and 2007, approximately 81.5%, 81.4% and 80.9%, respectively, of our total revenues were earned from aeronautical services, which are subject to price regulation under our maximum rates. These regulations may limit our flexibility in operating our aeronautical activities, which could have a material adverse effect on our business, results of operations, prospects and financial condition. In addition, several of the regulations applicable to our operations that affect our profitability are authorized (as in the case of our master development programs) or established (as in the case of our maximum rates) by the Ministry of Communications and Transportation for five-year terms. Except under limited circumstances, we generally do not have the unilateral ability to change our obligations (such as the investment obligations under our master development programs or the obligation under our concessions to provide a public service) or increase our maximum rates applicable under those regulations should our passenger traffic or other assumptions on which the regulations were based change during the applicable term. In addition, there can be no assurance that this price regulation system will not be amended in a manner that would cause additional sources of our revenues to be regulated.

The price regulatory system applicable to our airports imposes maximum rates for each airport.

The price regulatory system does not guarantee that our consolidated results of operations, or that the results of operations of any airport, will be profitable.

The system of price regulation applicable to our airports establishes an annual maximum rate for each airport, which is the maximum annual amount of revenues per work load unit (which is equal to one passenger or 100 kilograms (220 pounds) of cargo) that we may earn at that airport from services subject to price regulation. The maximum rates for our airports have been determined for each year through December 31, 2009. For a discussion of the framework for establishing our maximum rates and the application of these rates, see “Item 4, Information on the Company—Regulatory Framework— Aeronautical Services Regulation.” Under the terms of our concessions, there is no guarantee that the results of operations of any airport will be profitable.

15

Our concessions provide that an airport’s maximum rates will be adjusted periodically for inflation. Although we are entitled to request additional adjustments to an airport’s maximum rates under certain circumstances, including the amendment of certain provisions of the Mexican Airport Law, our concessions provide that such a request will be approved only if the Ministry of Communications and Transportation determines that certain events specified in our concessions have occurred. The circumstances under which we are entitled to an adjustment are described under “Item 4, Information on the Company—Regulatory Framework—Aeronautical Services Regulation—Special Adjustments to Maximum Rates.” There can be no assurance that any such request would be made or granted.

Our results of operations may be adversely affected by required efficiency adjustments to our maximum rates.

In addition, our maximum rates are subject to annual efficiency adjustments, which have the effect of reducing the maximum rates for each year to reflect projected efficiency improvements. For the five-year term ending December 31, 2009, an annual efficiency adjustment factor of 0.75% was established by the Ministry of Communications and Transportation. Future annual efficiency adjustments will be determined by the Ministry of Communications and Transportation in connection with the setting of each airport’s maximum rates every five years. For a description of these efficiency adjustments, see “Item 4, Information on the Company—Regulatory Framework—Aeronautical Services Regulation—Methodology for Determining Future Maximum Rates.” We cannot assure you that we will achieve efficiency improvements sufficient to allow us to maintain or increase our operating income as a result of the progressive decrease in each airport’s maximum rate.

The regulations pursuant to which the maximum rates applicable to our aeronautical revenues are established do not guarantee that we or any of our airports will be profitable.

The rate regulations applicable to our aeronautical services establish an annual maximum rate for each airport, which is the maximum annual amount of revenues per workload unit (which is equal to one terminal passenger or 100 kilograms of cargo) that we may earn at that airport from services subject to price regulation. The maximum rates for our airports have been determined by the Ministry of Communications and Transportation for each year through December 31, 2009. Under the terms of our concessions, there is no guarantee that our consolidated results of operations or the results of operations of any airport will be profitable.

Our concessions provide that an airport’s maximum rates will be adjusted periodically for inflation (determined by reference to the Mexican Producer Price IndexÍndice Nacional de Precios al Productor excluding petroleum). Although we are entitled to request additional adjustments to an airport’s maximum rates under certain circumstances (see “Item 4, Information on the Company—Regulatory Framework—Aeronautical Services Regulation—Special Adjustments to Maximum Rates”), our concessions provide that such a request will be approved only if the Ministry of Communications and Transportation determines that events specified in our concessions have occurred. Therefore, there can be no assurance that any such request would be granted.

If we exceed the maximum rate at any airport at the end of any year, we could be subject to sanctions.

Historically, we have set the prices we charge for regulated services at each airport in order to be as close as possible to our authorized maximum rate for that airport in any given year. We expect to continue to pursue this pricing strategy in the future. For example, in 2005, 2006 and 2007 our revenues subject to maximum rate regulation represented 99.2%, 98.8% and 99.7% of the amount we were entitled to earn under the maximum rates for all of our airports. However, there can be no assurance that we will be able to establish prices in the future that allow us to collect virtually all of the revenues we are entitled to earn from services subject to price regulation.

The specific prices we charge for regulated services are determined based on our forecasts of various factors, including of passenger traffic volumes, the Mexican Producer Price Index, excluding petroleum, and the value of the peso relative to the U.S. dollar. These variables are outside of our control. Our forecasts could differ from actual data, and, if these differences occur at the end of any year, they could cause us to exceed the maximum rate at any one or more of our airports during that year.

If we exceed the maximum rate at any airport at the end of any year, the Ministry of Communications and Transportation may assess a fine and may reduce the maximum rate at that airport in the subsequent year. The imposition of sanctions for violations of certain terms of a concession, including for exceeding an airport’s maximum rate, can result in termination of the concession if the relevant term has been violated and sanctions have been imposed at least three times for the same cause. In the event that any one of our concessions is terminated, our other concessions may also be terminated.

In prior years, in order to ensure our compliance with the maximum rate at a particular airport when the possibility of exceeding that maximum rate has arisen, we have taken actions in the latter part of the year, such as reducing our specific prices and offering discounts or rebates. We can offer no assurance that, should external factors cause us to risk exceeding our maximum rates close to the end of any given year, we will have sufficient time to take the actions described above in order to avoid exceeding our maximum rates prior to year-end.

The Mexican government may terminate or reacquire our concessions under various circumstances, some of which are beyond our control.

Our concessions are our principal assets and we are unable to continue our operations without them. A concession may be terminated by the Mexican government for certain prescribed reasons, including failure to comply with our master development programs, a temporary or permanent halt in our operations, actions affecting the operations of other concession holders in Mexico, failure to pay damages resulting from our operations, exceeding our maximum rates or failure to comply with any other material term of our concessions. Violations of certain terms of a concession (including violations for exceeding the applicable

17

maximum rate) can result in termination of a concession if sanctions have been imposed for violation of the relevant term at least three times. Violations of other terms of a concession can result in the immediate termination of the concession. Our concessions may also be terminated upon our bankruptcy or insolvency.

We would face similar sanctions for violations of the Mexican Airport Law or the regulations thereunder. Under applicable Mexican law and the terms of our concessions, our concessions may also be made subject to additional conditions, including under our renewed master development programs, which we may be unable to meet. Failure to meet these conditions may also result in fines, other sanctions and the termination of the concessions.

The Mexican government may also terminate one or more of our concessions at any time through reversion (rescate), if, in accordance with applicable Mexican law, it determines that it is in the public interest to do so. The Mexican government may also assume the operation of any airport (through a process known as arequisa) in the event of war, public disturbance or a threat to national security. In addition, in the case of aforce majeure event, the Mexican government may require us to implement certain changes in our operations. In the event of a reversion of the public domain assets that are the subject of our concessions, the Mexican government, under Mexican law, is required to compensate us for the value of the concessions or added costs based on the results of an audit performed by appraisers. In the event of a mandated change in our operations, the Mexican government is required to compensate us for the cost of that change. Similarly, in the event of an assumption of our operations other than in the event of war, the government is required to compensate us and any other affected parties for any resulting damages. There can be no assurance that we will receive compensation equivalent to the value of our investment in, or any additional damages related to, our concessions and related assets in the event of such action.

In the event that any one of our concessions is terminated, whether through revocation or otherwise, our other concessions may also be terminated. Thus, the loss of any concession would have a material adverse effect on our business and results of operations.

The Mexican government could grant new concessions that compete with our airports.

The Mexican government could grant additional concessions to operate existing government-managed airports, or authorize the construction of new airports, which could compete directly with our airports. Any competition from other such airports could have a material adverse effect on our business and results of operations. Under certain circumstances, the grant of a concession for a new or existing airport must be made pursuant to a public bidding process. In the event that a competing concession is offered in a public bidding process, we cannot assure you that we would participate in such process, or that we would be successful if we did participate.

18

The Ministry of Communications and Transportation could require us to monitor certain aircraft movements at our airports that we do not currently control, which could result in increased costs.

The Mexican Air Traffic Control Authority (Servicios a la Navegación en el Espacio Aéreo Mexicano) currently requires us to manage and control aircraft movements in and out of our arrival and departure gates and remote boarding locations directly at our Puerto Vallarta International Airport and our Guadalajara International Airport. At our other airports, these aircraft movements are monitored directly by the Mexican Air Traffic Control Authority. Should the Mexican Air Traffic Control Authority require us to control these aircraft movements directly at any or all of our other ten airports in the future, our results of operations could be negatively impacted by increased operating insurance and liability costs resulting from taking on these obligations.

Risks Related to Our Controlling Stockholder

AMP controls our management, and AMP’s interests may differ from those of other stockholders.

AMP holds Series BB shares currently representing 15% of our outstanding capital stock. Pursuant to our bylaws, AMP (as holder of our Series BB shares) has the right (upon consultation with our Nominations and Compensation Committee) to appoint and remove our top-level executive officers, to elect four members of our board of directors and their alternates and to designate three of the members of our Operating Committee and 20% of the members of each other board committee (or one member of any committee consisting of fewer than five members). AMP (as holder of our Series BB shares) also has the right pursuant to our bylaws to veto certain actions requiring approval of our stockholders (including the payment of dividends, the amendment of our bylaws and any decision that has the objective to modify or annul its right to appoint our top-level executive officers). Pursuant to our bylaws, if at any time AMP (as the holder of our Series BB shares) were to hold less than 7.65% of our capital stock in the form of Series BB shares, it would lose its veto rights (but not other special rights). If at any time after August 25, 2014 AMP were to hold less than 7.65% of our capital stock in the form of Series BB shares, such shares would be mandatorily converted into Series B shares, which would cause AMP to lose all of its special rights. In addition, stockholders of AMP have allocated among themselves certain veto rights relating to the exercise by AMP of its veto and other rights, which increases the risk of impasse at the stockholders’ meeting of AMP and ultimately at our stockholders’ meetings.

AMP’s veto, appointment and other rights could adversely impact our operations and constitute an obstacle for us to bring in a new strategic stockholder and/or operator. Through the right to appoint and remove members of our senior management, AMP directs the actions of our management in areas such as business strategy, financing, distributions, acquisitions and dispositions of assets or businesses. The interests of AMP may differ from those of our other stockholders and be contrary to the preferences and expectations of our other stockholders and we can offer no assurance that AMP and the officers appointed by AMP will exercise their rights in ways that favor the interests of our other stockholders.

19

If AMP should decide to sell all or a portion of its interest in us, our operations could be adversely affected.

AMP currently exercises a substantial influence over our management, as described above. Our bylaws and certain of the agreements executed in connection with the privatization process prohibited AMP from transferring any of its Series BB shares before August 25, 2004. Since that date, AMP has been permitted to transfer up to 49% of its Series BB shares without restriction. After August 25, 2009, AMP may additionally sell in any year up to 20% of its remaining 51% interest in our Series BB shares. Our bylaws provide that, subject to certain exceptions, Series BB shares must be converted into Series B shares prior to transfer. Should AMP divest its interest in us or cease to hold Series BB shares, our management could change significantly and our operations could be adversely affected as a result. The termination of the technical assistance agreement with AMP may also adversely affect or disrupt our operations.

Official inquiries relating to certain requirements of the privatization guidelines and the participation agreement relating to our privatization could have a material adverse effect on our operations or the value of our securities.

In 1999, as part of the first stage in the process of opening Mexico’s airports to private investment, the Mexican government sold a 15% equity interest in us to AMP pursuant to a public bidding process.

Pursuant to the guidelines published by the Mexican government during the first phase of our privatization and the participation agreement setting forth the rights and obligations of each of the parties involved in our privatization, AMP assumed certain rights and obligations.

In 2004 and 2005, various reports in the Mexican press alleged that AMP did not comply with certain of its obligations under the privatization guidelines and the participation agreement, specifically the requirements related with the nationality of AMP’s Mexican partner. In June 2005, the Permanent Commission of the Mexican Federal Congress (Comisión Permanente del Congreso Federal) requested that the Ministry of Communications and Transportation and other agencies of the federal government investigate these allegations and report on our share ownership structure and certain related matters.

In January 2006, the previous Mexican partner sold its 25.5% interest in AMP to Controladora Mexicana de Aeropuertos, S.A. de C.V., or Controladora Mexicana, a Mexican joint venture company 50% owned by Pal Aeropuertos, S.A. de C.V., and 50% owned by Promotora Aeronáutica del Pacífico, S.A. de C.V. The Ministry of Communications and Transportation approved the sale to Controladora Mexicana, including its role as AMP’s Mexican partner pursuant to the privatization guidelines and the participation agreement relating to our privatization.

Although we believe AMP satisfies all their requirements under the privatization guidelines and the participation agreement, there can be no assurance that future allegations or official inquiries relating to AMP’s compliance with its obligations under those requirements will not take place. In the event of future inquiries or an official finding that AMP is or was not in compliance with the requirements of the privatization guidelines or the participation

20

agreement, AMP could be subject to fines and the technical assistance agreement between us and AMP could be terminated, which could have a material adverse effect on our operations. In addition, there can be no assurance that any such developments would not result in a material decrease in the market value of our shares or ADSs.

Risks Related to Mexico

Our business is significantly dependent upon the volume of air passenger traffic in Mexico and negative economic developments in Mexico would adversely affect our business and results of operations.

Mexican domestic passengers in recent years have represented approximately two-thirds of the passenger traffic volume in our airports. In addition, all of our assets are located, and all of our operations are conducted, in Mexico. As a result, our business, financial condition and results of operations could be adversely affected by the general condition of the Mexican economy, by a devaluation of the peso, by inflation and high interest rates in Mexico, or by political, social and economic developments in Mexico.

Mexico has, particularly from 1982 to 1987, from December 1994 through 1995 and in 1998, experienced adverse economic conditions, including slow or negative economic growth and high levels of inflation. In addition, financial turmoil in Argentina, Brazil, Venezuela and elsewhere over the past decade had the effect of producing volatility in the international financial markets, which slowed Mexico’s economic growth.

If the Mexican economy falls into a recession or if inflation and interest rates increase significantly, our business, results of operations, prospects and financial condition could suffer material adverse consequences because, among other things, demand for transportation services may decrease. We cannot assure you that similar events will not occur, or that any recurrence of these or similar events would not adversely affect our business, results of operations, prospects and financial condition.

Depreciation or fluctuation of the peso relative to the U.S. dollar could adversely affect our results of operations and financial condition.

Following the devaluation of the peso and the economic crisis beginning in 1994, the aggregate passenger traffic volume in our airports in 1995 (then operated by our predecessor) decreased as compared to prior years, reflecting a decrease in Mexican passenger traffic volume that more than offset an increase in international passenger traffic volume. Recently, the peso has increased in value against the U.S. dollar, which could lead to a decrease in international passenger traffic, which may not be offset by any increase in domestic passenger traffic. Any future significant appreciation or depreciation of the peso could impact our aggregate passenger traffic volume, which could have a material adverse effect on our results of operations.

As of December 31, 2007, we had Ps. 578.6 million of indebtedness. Although we currently intend to fund the investments required by our business strategy and under our master development programs primarily through cash flow from operations, we signed an unsecured credit agreement with Banamex on August 31, 2007, to fund the capital expenditures that we anticipate undertaking in the period from September 2007 to December 2009 at our Los Cabos,

21

Puerto Vallarta, Hermosillo and Guanajuato international airports. However, depending on economic conditions and credit-market conditions in Mexico, we may incur dollar-denominated debt to finance investments we make in the future. In this case, a devaluation of the peso would increase the debt service cost of such dollar-denominated indebtedness and result in foreign exchange losses.

Fluctuations in the exchange rate between the peso and the U.S. dollar, particularly depreciations, also may also adversely affect the U.S. dollar equivalent of the peso price of the Series B shares on the Mexican Stock Exchange. As a result, such peso depreciations will likely affect the market price of the ADSs. Exchange rate fluctuations would also affect the ADS depositary’s ability to convert into U.S. dollars, and make timely payment of, any peso cash dividends and other distributions paid in respect of the Series B shares.

Political conditions in Mexico could materially and adversely affect Mexican economic policy or business conditions and, in turn, our operations.

The Mexican government has exercised, and continues to exercise, significant influence over the Mexican economy. Mexican governmental actions concerning the economy could have a significant impact on Mexican private sector entities in general, as well as on market conditions and prices and returns on Mexican securities, including our securities.

On July 2, 2006, Mexico held presidential and federal congressional elections, and Felipe Calderón Hinojosa, the candidate of thePartido Acción Nacional, or the PAN, won the presidency by a very narrow margin over Andrés Manuel López Obrador, presidential candidate of theAlianza por el Bien de Todos, or the ABT. According to the Federal Electoral Institute (Instituto Federal Electoral), Mexican congressional elections resulted in a divided Mexican Congress with the PAN representing the largest group but failing to obtain majority control. The ABT, as the leading opposition party in the presidential elections, contested the results of the presidential election, and Mr. López Obrador and other members of the ABT led a number of protests and civil disobedience actions. On September 6, 2006, the Federal Electoral Tribunal (Tribunal Electoral del Poder Judicial de la Federación) declared Mr. Calderón the definitive winner of the presidential election. Mr. Calderón assumed office on December 1, 2006, and his term as president will run until November 30, 2012. Support for the claims made by Mr. López Obrador has decreased since Mr. Calderón took office.

As a result of Mexican federal elections held on July 2, 2006, no political party has a number of legislators sufficient to control any of the chambers of the Mexican Congress. This situation will continue, at least, until the next election of federal representatives in 2009 and may hinder the adoption of any significant legal reforms that are needed in Mexico. We cannot assure you that Mexican political events, over which we have no control, will not have an adverse effect over our financial conditions, results of operations or the market price of our securities.

22

Adverse economic conditions in Mexico may adversely affect our financial condition or results of operations.

All of our operations are conducted in Mexico and are dependent upon the performance of the Mexican economy. As a result, our business, financial condition or results of operations may be affected by the general condition of the Mexican economy, over which we have no control. In the past, Mexico has experienced economic crises, caused by internal and external factors, characterized by exchange rate instability (including large devaluations), high inflation, high domestic interest rates, economic contraction, a reduction of international capital flows, a reduction of liquidity in the banking sector and high unemployment rates. We cannot assume that such conditions will not return or that such conditions will not have a material adverse effect on our business, financial condition or results of operations.

Mexico experienced a period of slow growth from 2001 through 2003, primarily as a result of the downturn in the U.S. economy. In 2001, Mexico’s GDP declined by 0.2%, while inflation reached 4.4%. In 2002, GDP grew by 0.8% and inflation reached 5.7%. In 2003, GDP grew by 1.4% and inflation was 4.0%. In 2004, GDP grew by 4.2% and inflation increased to 5.2%. In 2005, GDP grew by approximately 2.8% and inflation decreased to 3.3%. In 2006, GDP grew by approximately 4.8% and inflation reached 4.1%. In 2007, GDP grew by approximately 3.3% and inflation declined to 3.8%.

Mexico also has, and is expected to continue to have, high real and nominal interest rates. The annualized interest rates on 28-day Cetes averaged approximately 11.3%, 7.1%, 6.2%, 6.8%, 9.2%, 7.2% and 7.2% for 2001, 2002, 2003, 2004, 2005, 2006 and 2007, respectively. To the extent that we incur peso-denominated debt in the future, it could be at high interest rates.

If the Mexican economy falls into a recession, if inflation or interest rates increase significantly or the Mexican economy is otherwise adversely impacted, our business, financial condition or results of operations could be materially and adversely affected.

We may be liable for property tax claims asserted against us by certain municipalities.

Claims have been asserted against us by the municipalities of Mexicali and Tijuana, for the payment of property taxes with respect to the real property on which we operate our airports in those cities, and similar claims may be asserted by other municipalities where we operate our airports. The total amount of the property tax claims outstanding in each of Mexicali and Tijuana are Ps. 89.0 million and Ps. 146.4 million, respectively, although either of these amounts could increase if the underlying claims are not resolved in our favor as a result of penalty and interest surcharges. In the case of Aguascalientes, we received a memorandum from the Aguascalientes Ministry of Finance stating that the Aguascalientes International Airport is exempt from property taxes. We continue to defend the claim in order to obtain a definitive judicial resolution, which we expect will be in our favor. We are also seeking dismissal of remaining claims pending in Mexicali and Tijuana.

In Tijuana, the court had ordered the temporary encumbrance of certain of our assets, including our concession to operate the Tijuana International Airport, pending our deposit of a

23

bond with the court as provisional security, in accordance with Mexican judicial procedures, pending the final resolution of the underlying claims. Although the encumbered assets did not affect the operation of the airport, on February 9, 2006, an irrevocable standby letter of credit was issued by a financial institution on behalf of the Tijuana airport for Ps. 141.8 million in order to release the encumbrance. This amount differs from the original amount of the tax claim because it was an estimate intended to guarantee payment of both the tax and penalties for late payment. On March 25, 2008, the Tijuana airport received an initial ruling declaring null and void the payment required by municipal authority. A court has also ordered the temporary encumbrance of a portion of the revenues from the parking garage that we operate at the Mexicali International Airport to guarantee the property-tax claims of the Mexicali municipal government. The cumulative amount of such encumbrances is Ps. 5.4 million (nominal pesos). During 2006 we obtained a favorable ruling in the first instance upon a judicial annulment it filed, however, the municipality appealed this decision, and the case is still pending resolution. In the event of a definitive decision in our favor in the annulment proceeding that we have initiated with respect to the Mexicali claim, we expect to recover our encumbered revenues in full.

We believe that the Mexican government, as the owner of the real property upon which we operate our airports, would be responsible for paying these taxes directly if a court were to determine that these taxes must be paid in response to any future proceedings, for which reason we do not believe that liabilities related to any claims or proceedings against us are likely to have, individually or in the aggregate, a material adverse effect on our consolidated financial condition or results of operations. Nonetheless, the Mexican government has indicated publicly that it may propose an amendment to the Mexican Constitution and other laws pursuant to which we could be liable to municipalities for property taxes in the future. If such changes were to occur, and any amounts owed were substantial, these tax liabilities could have a material adverse effect on our financial condition or results of operations.

Changes to Mexican laws, regulations and decrees applicable to us could have a material adverse impact on our results of operations.

The Mexican government has in recent years implemented various changes to the tax laws applicable to Mexican companies, including us. The terms of our concessions do not exempt us from any changes to the Mexican tax laws. Should the Mexican government implement changes to the tax laws that result in our having significantly higher tax liability, we would be required to pay the higher amounts due pursuant to any such changes, which could have a material adverse impact on our results of operations. In addition, changes to the Mexican constitution or to any other Mexican laws could also have a material adverse impact on our results of operations.

The Mexican Bureau of Civil Aviation (Dirección General de Aeronáutica Civil) is responsible for establishing the official operating schedules of our airports. Outside of our airports’ official hours of operation, we are permitted to double our airport charges for services that we provide. The Mexican Bureau of Civil Aviation has issued a decree extending the official operating schedule of our Morelia International Airport and our Los Cabos International Airport to 24 hours per day. This decree deprives us of the ability to double our airport charges for off-hour services, and, for this reason, we have challenged the decree in court, see “Item 8—

24

Legal Proceedings—Modification of the operating schedules of our Morelia International Airport and our Los Cabos International Airport” for a more detailed discussion of this matter. There can be no assurance that we will be successful in avoiding this decree. In addition, there can be no assurance that other airports will not adopt similar decrees.

Minority stockholders may be less able to enforce their rights against us, our directors, or our controlling stockholders in Mexico.

Under Mexican law, the protections afforded to minority stockholders are different from those afforded to minority stockholders in the United States. For example, because provisions concerning fiduciary duties of directors have only recently been incorporated into the new Securities Market Law, it may be difficult for minority stockholders to bring an action against directors for breach of this duty and achieve the same results as in most jurisdictions in the United States. Procedures for class action lawsuits do not exist under applicable Mexican law. Therefore, it may be more difficult for minority stockholders to enforce their rights against us, our directors, or our controlling stockholders than it would be for minority stockholders of a U.S. company.

We are subject to different corporate disclosure and accounting standards than U.S. companies.

A principal objective of the securities laws of the United States is to promote full and fair disclosure of all material corporate information, including accounting information. However, there may be different or less publicly available information about foreign issuers of securities listed in the United States than is regularly made available by public companies in countries with highly developed capital markets, including the United States.

In addition, accounting standards and disclosure requirements in Mexico differ from those of the United States. In particular, we prepare our consolidated financial statements in accordance with MFRS, which differ from U.S. GAAP in a number of respects. For example, we are required to incorporate the effects of inflation directly in our accounting records and published consolidated financial statements for periods prior to January 1, 2008. While we are required to reconcile our net income and stockholders’ equity to those amounts that would be derived under U.S. GAAP in our annual consolidated financial statements, the effects of inflation accounting under MFRS are not eliminated in such reconciliation in our annual consolidated financial statements that incorporate the effects of inflation. For this and other reasons, the presentation of MFRS consolidated financial statements and reported earnings may differ from that of U.S. companies in this and other important respects. Please see Note 24 to our audited consolidated financial statements and “Item 3, Key Information—Selected Financial Data—Recent Changes Affecting Inflation Accounting.”

Risks Related to Global Economy

Developments in other countries may affect us.

The market value of securities of Mexican companies may be, to varying degrees, affected by economic and market conditions in other countries. Although economic conditions in these countries may differ significantly from economic conditions in Mexico, investors’

25

reactions to developments in any of these other countries may have an adverse effect on the market value of securities of Mexican issuers. In past years, prices of both Mexican debt and equity securities have been adversely affected by a sharp drop in Asian securities markets and economic crises in Russia, Brazil, Argentina and Venezuela.

Our business could be adversely affected by a downturn in the U.S. economy.

In recent years, economic conditions in Mexico have become increasingly correlated to economic conditions in the United States. Therefore, adverse economic conditions in the United States could have a significant adverse effect on the Mexican economy. In 2007, 32.2% of the terminal passengers served by our airports arrived and departed, respectively, on international flights, primarily to the United States.

Our business is particularly influenced by trends in the United States relating to leisure travel, consumer spending and international tourism. Events and conditions negatively affecting the U.S. economy will likely have a material adverse effect on our business, results of operations, prospects and financial condition.

We cannot predict what effect any future terrorist attacks or threatened attacks on the United States or any retaliatory measures taken by the United States in response to these events may have on the U.S. economy or leisure travel trends. An economic downturn in the United States may negatively affect our results of operations and a prolonged economic crisis in the United States would likely have a material adverse effect on our results of operations.

Item 4. Information on the Company

HISTORY AND DEVELOPMENT OF THE COMPANY

We were incorporated in 1998 as part of the Mexican government’s program for the opening of Mexico’s airports to private investment. We hold concessions to operate, maintain and develop 12 airports in the Pacific and central regions of Mexico. Each of our concessions has a term of 50 years beginning on November 1, 1998. The term of each of our concessions may be extended by the Ministry of Communications and Transportation under certain circumstances for up to 50 additional years. As operator of the 12 airports under our concessions, we charge airlines, passengers and other user’s fees for the use of the airports’

27

facilities. We also derive rental and other income from commercial activities conducted at our airports, such as the leasing of space to restaurants and retailers. For a description of our capital expenditures, see Item 5 hereof.

Grupo Aeroportuario del Pacífico, S.A.B. de C.V. is a corporation (sociedad anónima bursátil de capital variable) organized under the laws of Mexico. The address of our registered office is as set forth on the cover of this Form 20-F. Our telephone number is (52) (33) 3880-1100. Our U.S. agent is Puglisi & Associates. Our U.S. agent’s address is 850 Library Avenue, Suite 204, Newark, Delaware 19711.

Opening of Mexican Airports to Investment

In February 1998, the Mexican government issued the Investment Guidelines for the Opening of Investment in the Mexican Airport System. Under these guidelines, the Ministry of Communications and Transportation identified 35 of Mexico’s 58 principal airports as being suitable for investment. These 35 airports were divided into four groups: the Pacific Group (currently consisting of our 12 airports),Grupo Aeroportuario del Sureste, or the Southeast Group (currently consisting of nine airports),Grupo Aeroportuario de la Ciudad de México, D.F., or the Mexico City Group (currently consisting of one airport) andGrupo Aeroportuario del Centro-Norte, or the Central-North Group (currently consisting of 13 airports). The guidelines generally provided for the airport groups to become open to investment through a two-stage program. All of the groups except the Mexico City Group have completed both stages of the program.

In the first stage, a series of public bidding processes were conducted to award a minority interest in each airport group to a strategic stockholder. In the second stage, all or a portion of the remaining interest in each airport group was sold through public offerings in the Mexican and international capital markets.

As a result of the opening of Mexico’s airports to investment, we and our subsidiaries are no longer subject to the Mexican regulations applicable to government wholly owned companies. We believe that this provides us greater flexibility to develop and implement our business strategy and to respond to potential business opportunities.

Investment by AMP

In 1999, as part of the first stage in the process of opening Mexico’s airports to investment, the Mexican government sold a 15% equity interest in us to AMP, pursuant to a public bidding process.

The following are AMP’s current stockholders:

• AENA Desarrollo Internacional S.A., or AENA, owns 33.33% of AMP. AENA is a wholly owned subsidiary of Aeropuertos Españoles y Navegación Aérea, a Spanish state-owned company that manages all airport operations in Spain. Aeropuertos Españoles y Navegación Aérea operates 47 airports in Spain, handling approximately 193.2 million total passengers in Spain in 2006, making it one of the largest airport operators in the world. Pursuant to the privatization guidelines published by the

28

Mexican government during the first phase of our privatization, requiring our strategic stockholder to have, among other qualifications, an operating partner and a Mexican partner, AENA is one of AMP’s two key partners, acting as its operating partner. In addition to its investment in AMP, AENA also directly manages four other airports in Latin America. In addition, AENA owns 10.0% of Airport Concessions and Development Limited, which owns a British airport company that operates thirteen airports in Europe, North America and Latin America through ownership, concession or management arrangements.

• Controladora Mexicana owns 33.33% of AMP. Controladora Mexicana is a Mexican joint venture company 50% owned by Pal Aeropuertos, S.A. de C.V., and 50% owned by Promotora Aeronáutica del Pacífico, S.A. de C.V. Pal Aeropuertos, S.A. de C.V. is a Mexican special purpose vehicle owned by Eduardo Sánchez Navarro Redo, an individual Mexican investor with substantial interests in Mexican real estate. Promotora Aeronáutica del Pacífico, S.A. de C.V. is a Mexican special purpose vehicle owned by Laura Diez Barroso Azcárraga and her husband, Carlos Laviada Ocejo. Mrs. Diez Barroso has extensive experience in the magazine publishing industry and currently serves on the boards of directors of Teléfonos de México, S.A. de C.V., Grupo Financiero Inbursa S.A. and Royal Caribbean Cruises Ltd. Mr. Laviada Ocejo, an individual Mexican investor with substantial interests in real estate development and automobile dealerships in Mexico City, currently serves on the board of directors of Toyota Mexico Dealers A.C. Pursuant to the privatization guidelines discussed above, Controladora Mexicana is AMP’s second key partner, acting as its Mexican partner.

• Desarollo de Concesiones Aeroportuarias S.A., or DCA, a subsidiary of Abertis Infraestructuras, S.A. (“Abertis”), owns 33.33% of AMP. Abertis is a leading infrastructure manager in Europe; carrying out projects in the fields of motorways, telecommunications, airports, parking and logistics parks. Abertis operates in 17 countries on three continents. Abertis is listed on the Spanish stock exchange (Bolsa de Madrid) and forms part of the Ibex 35 index.

In 1999, AMP paid the Mexican government a total of Ps. 2,453.4 million (nominal pesos, excluding interest) (U.S.$ 261 million based on the exchange rates in effect on the dates of payment) in exchange for:

• All of our Series BB shares, representing 15% of our outstanding capital stock;

• an option to subscribe for up to 5% of newly issued Series B shares (since expired); and

• the right and obligation to enter into various agreements with us and the Mexican government, including a participation agreement setting forth the rights and obligations of each of the parties involved in the privatization, including AMP, a 15-year technical assistance agreement setting forth AMP’s right and obligation to provide technical assistance to us in exchange for an annual fee and a stockholders’ agreement under terms established during the bidding process. These agreements are described in greater detail in Item 7 hereof.

29

Under the technical assistance agreement, AMP provides management and consulting services and transfers industry expertise and technology to us in exchange for a fee. In 2007, this fee amounted to Ps. 125.9 million. The agreement provides us an exclusive license in Mexico to use all technical assistance and expertise transferred to us by AMP or its stockholders during the term of the agreement. The agreement is scheduled to expire August 29, 2014 and terminates on the date of the expiration of the participation agreement. The agreement automatically renews for successive five-year terms unless one party provides the other a notice of termination at least 60 days prior to a scheduled expiration date. Under our bylaws, a decision by us not to renew the technical assistance agreement is subject to the approval of 51% of Series B stockholders other than AMP or any related party of AMP (to the extent that AMP or any such related party holds Series B shares). A party may terminate the technical assistance agreement prior to its expiration date upon non-compliance with its terms by the other party. AMP provides us assistance in various areas, including development of our commercial activities, preparation of marketing studies focusing on increasing passenger traffic, assistance with the preparation of the master development programs that we are required to submit to the Ministry of Communications and Transportation and the improvement of our airport operations.

The technical assistance fee for 2000 and 2001 was fixed at U.S.$ 7.0 million (adjusted annually for U.S. inflation since August 25, 2000). Subsequent to January 1, 2002, the technical assistance fee has been equal to the greater of U.S.$ 4.0 million adjusted annually for inflation since August 25, 2000 (measured by the U.S. consumer price index) or 5% of our annual consolidated income from operations (calculated prior to deducting the technical assistance fee and depreciation and amortization and in each case determined in accordance with MFRS). We believe that this structure creates an incentive for AMP to increase our annual consolidated earnings. AMP is also entitled to reimbursement for the out-of-pocket expenses it incurs in its provision of services under the agreement.

The technical assistance agreement allows AMP, its stockholders and their affiliates to render additional services to us only if our Acquisitions Committee determines that these related persons have submitted the most favorable bid in a public bidding process involving at least three unrelated parties. For a description of this Committee see Item 6 herein.

Pursuant to our bylaws, AMP (as holder of our Series BB shares) has the right (upon consultation with our Nominations and Compensation Committee) to appoint and remove our top-level executive officers, to elect four members of our board of directors and their alternates and to designate three of the members of our Operating Committee and 20% of the members of each other board committee (or one member of any committee consisting of fewer than five members). AMP (as holder of our Series BB shares) also has the right pursuant to our bylaws to veto certain actions requiring approval of our stockholders (including the payment of dividends, the amendment of our bylaws and any decision that has the objective to modify or annul its right to appoint our top-level executive officers). Pursuant to our bylaws, if at any time AMP (as the holder of our Series BB shares) were to hold less than 7.65% of our capital stock in the form of Series BB shares, it would lose its veto rights (but not other special rights). If at any time after August 25, 2014 AMP were to hold less than 7.65% of our capital stock in the form of

30

Series BB shares, such shares would be mandatorily converted into Series B shares, which would cause AMP to lose all of its special rights. In addition, stockholders of AMP have allocated among themselves certain veto rights relating to the exercise by AMP of its veto and other rights, which increases the risk of impasse at the stockholders’ meeting of AMP and ultimately at our stockholders’ meetings.

Our bylaws, the participation agreement and the technical assistance agreement also contain certain provisions designed to avoid conflicts of interest between AMP and us, such as approval of certain related-party transactions by designated committees.

Our bylaws and certain of the agreements executed in connection with the privatization process prohibited AMP from transferring any of its Series BB shares before August 25, 2004. Since that date, AMP has been permitted to transfer up to 49% of its Series BB shares without restriction. After August 25, 2009, AMP may additionally sell in any year up to 20% of its remaining 51% interest in our Series BB shares. Our bylaws provide that, subject to certain exceptions, Series BB shares must be converted into Series B shares prior to transfer.

AMP Shares in Bancomext Trust

As required under the participation agreement entered into in connection with the Mexican government’s sale of our Series BB shares to AMP, AMP has transferred its Series BB shares to a trust, the trustee of which is Banco Nacional de Comercio Exterior, S.N.C., or Bancomext. For a description of this trust, see Item 7 hereof.

Pursuant to the terms of the trust, AMP may direct the trustee to vote only shares representing up to 10% of our capital stock. Any shares in excess of 10% are voted by the trustee in accordance with the vote of the majority of Series B shares. The trust does not affect the veto and other special rights granted to the holders of Series BB shares described above.

Global Offering and Establishment of ADR Facility with New York Stock Exchange Listing

In 1999, 85% of our capital stock was transferred from the Mexican government to a trust established in Nacional Financiera S.N.C. (“NAFIN”), a Mexican government-owned entity. In February 2006, we conducted an initial public offering to allow NAFIN to dispose of its 85% interest in us. Through this offering, all of our outstanding Series B shares were sold to the public in Mexico, the United States and elsewhere, and NAFIN ceased to be a stockholder. We received no proceeds from this offering. At the same time, we established an American Depositary Receipt facility with the Bank of New York and obtained approval to list our ADSs on the New York Stock Exchange. In addition, we registered our Series B shares with the National Securities Registry (Registro Nacional de Valores) and listed our Series B shares on the Mexican Stock Exchange.

BUSINESS OVERVIEW

Our Operations

We operate 12 airports, which serve two major metropolitan areas (Guadalajara and Tijuana), several tourist destinations, such as Puerto Vallarta, Los Cabos, La Paz and Manzanillo, and a number of mid-sized cities, such as Hermosillo, Guanajuato, Morelia, Aguascalientes, Mexicali and Los Mochis. Our airports are located in nine of the 32 Mexican states, covering a territory of approximately 566,000 square kilometers, with a population of approximately 25.6 million according to the Mexican National Institute of Statistics (Instituto Nacional de Estadística, Geografía e Informática). All of our airports are designated as international airports under Mexican law, meaning that they are all equipped to receive international flights and maintain customs, refueling and immigration services managed by the Mexican government.

Our airports handled approximately 20.5 million and 23.6 million terminal passengers in 2006 and 2007, respectively, which we believe makes us the largest private airport operator in the South-Central Americas. As of December 31, 2007, five of our airports ranked among the top ten busiest airports in Mexico based on commercial aviation passenger traffic, according to data published by the Mexican Bureau of Civil Aviation. According to figures of the Mexican Bureau of Civil Aviation, our commercial aviation passenger traffic accounted for approximately 27.4% and 27.2% of all arriving and departing commercial aviation passengers in Mexico in 2006 and 2007, respectively. In 2007, we recorded revenues of Ps. 3,477.3 million and net income of Ps. 1,402.8 million.

Our airports serve several major international routes, including Guadalajara-Los Angeles, which, in 2007, ranked as the second busiest international route in Mexico by total number of passengers according to the Mexican Bureau of Civil Aviation. In addition, our airports serve major resort destinations such as Puerto Vallarta and Los Cabos, which are among the most popular destinations in Mexico visited by tourists from California. Our airports also serve major domestic routes, including Guadalajara-Mexico City, which was the country’s third busiest route in 2007, handling over 1.6 million total passengers, according to the Mexican Bureau of Civil Aviation. Other top domestic routes in terms of total passenger traffic include Mexico City-Tijuana and Guadalajara-Tijuana and Mexico City-Tijuana which ranked fourth and fifth among the busiest domestic routes in Mexico in 2007, according to the Mexican Bureau of Civil Aviation.

Mexico and the United States are party to a bilateral aviation agreement, which was last amended on December 12, 2005 (the amendment was published in the Mexican Federal GazetteDiario Oficial de la Federación on July 18, 2006). The most recent amendment increased, from two each to three each, the number of Mexican and U.S. carriers eligible to operate routes between fourteen cities in Mexico and any U.S. city. The amendment had immediate effect for twelve specified cities in Mexico, including the following cities in which we operate: Manzanillo, Puerto Vallarta and San José del Cabo (the site of our Los Cabos International Airport). The amendment took effect with respect to the cities of Monterrey and Guadalajara on October 27, 2007. We believe that our business has benefited from and will continue to benefit from the amendment to the bilateral aviation agreement.

32

In 2005, the Ministry of Communications and Transportation awarded domestic airline licenses to four new low-cost carriers, two of which (Avolar and Aerolíneas Mesoamericanas, or Alma) are based at our airports (Tijuana International Airport and Guadalajara International Airport, respectively). In 2006, one new low-cost carrier (VivaAerobus) received a license from the Ministry of Communications and Transportation. It began operations in November 2006. By the end of 2007, Volaris operated in eight of our 12 airports, Alma in six, Avolar and VivaAerobus in five, Click of Mexicana in four and Interjet in three airports.

Guadalajara and Tijuana are among Mexico’s most important manufacturing, industrial and commercial centers. Both cities have significant maquiladoraindustries. A maquiladoraplant is a manufacturing facility to which most raw materials are imported and from which finished products are exported, with the manufacturer paying tariffs only on the value added in Mexico.Maquiladoraplants were originally concentrated along the Mexico-U.S. border, but more recently have moved farther south in order to access lower labor costs and a larger and more diverse labor pool, and to take greater advantage of certain inputs available from Mexican suppliers. In 2007, our Guadalajara International Airport and our Tijuana International Airport constituted Mexico’s third and fifth busiest airports, respectively, in terms of passenger traffic according to the Mexican Airport and Auxiliary Services Agency. In 2006 and 2007, our Guadalajara International Airport and our Tijuana International Airport together represented approximately 49.3% and 51.2%, respectively, of our terminal passenger traffic and 45.9% and 47.2%, respectively, of our total revenues.

Four of our airports, Puerto Vallarta International Airport, Los Cabos International Airport, La Paz International Airport and Manzanillo International Airport, serve popular Mexican tourist destinations. Of these tourist destinations, Puerto Vallarta and Los Cabos are

33

the largest, with Puerto Vallarta constituting Mexico’s fourth largest international tourist destination and Los Cabos the sixth largest in terms of visitors in 2006, according to the Mexican National Institute of Migration (Instituto Nacional de Migración). Puerto Vallarta attracted approximately 3.1 million terminal passengers in 2007, while Los Cabos attracted approximately 2.9 million terminal passengers in 2007. In 2007, our Puerto Vallarta International Airport and our Los Cabos International Airport together represented 25.6% of our terminal passengers and 31.2% of our total revenues.

Mexico was the 8th largest tourist destination in the world in 2006 in terms of international arriving tourists (21.4 million), according to the World Tourism Organization. Within Latin America and the Caribbean, Mexico ranked first in 2006 in terms of number of foreign visitors and income from tourism, according to the World Tourism Organization. The tourism industry is one of the largest generators of foreign exchange in the Mexican economy, contributing U.S.$ 12.2 billion in 2006, according to the World Tourism Organization.

The remaining six airports in our group serve mid-sized cities—Hermosillo, León, Morelia, Aguascalientes, Mexicali and Los Mochis—with diverse economic activities. These cities are industrial centers (Hermosillo, León, Aguascalientes and Mexicali) and/or the hubs of important agricultural regions (León, Morelia and Los Mochis). Of these six airports, Hermosillo has the greatest passenger traffic volume. In 2007, Hermosillo accounted for approximately 5.7% of our terminal passenger traffic and 4.5% of our total revenues. In 2007, our six airports serving mid-sized cities accounted for approximately 19.4% of our terminal passenger traffic and 17.8% of our total revenues.

Our Sources of Revenues

Aeronautical Services

Aeronautical services represent the most significant source of our revenues. In 2005, 2006 and 2007, aeronautical services revenues represented approximately 81.5%, 81.4% and 80.9%, respectively, of our total revenues. All of our revenues from aeronautical services are regulated under the maximum-rate price regulation system applicable to our airports.

Our revenues from aeronautical services are derived principally from the charges listed below. Aeronautical services revenues are principally dependent on the following factors: passenger traffic volume, the number of air traffic movements, the weight of the aircraft, the duration of an aircraft’s stay at the airport and the time of day the aircraft operates at the airport.

Passenger Charges

We earn a passenger charge for each departing passenger on an aircraft (other than diplomats, infants, transfer and transit passengers). We do not collect passenger charges from arriving passengers. Passenger charges are automatically included in the cost of a passenger’s ticket and we issue invoices for those charges to each airline on a weekly basis and record an account receivable for the invoice corresponding to a flight during the actual month of the flight.

Pursuant to our agreement with our principal airline customers signed in 2003 and renewed in March 2005, our principal airline customers were required to pay us no later than

34

152 days after our invoice delivery date. In 2006 and 2007, on a weighted average basis, we generally have received payment within 84 to 93 days and 78 to 88 days, respectively. The actual term for payment is dependent upon interest rates on short-term Mexican treasury bills, orCetes, with longer payment periods during periods of lower interest rates (within a defined range).

In March 2005, we entered into a renewal agreement with the Air Transportation Chamber that expired in December 2006. In December 2006 a new agreement was signed, pursuant to which, in March 2007, we increased domestic passenger charges by amounts ranging from 7.28% to 17.28% at all of our airports and increased international passenger charges by amounts ranging from 7.28% to 15.28% at all of our airports. The new agreement is set to cover an increasing percentage of total passenger charges over the years 2007, 2008 and 2009 and has set prices for each aeronautical service over this three-year period, with increases only possible as a result of the average of increases in the Mexican Consumer Price Index (Índice Nacional de Precios al Consumidor)and the Producers Price Index Excluding Petroleum (Índice Nacional de Precios al Productor, excluyendo petróleo)published by the Mexican Central Bank.

It is important to note that, although the Ministry of Communications and Transportation may authorize an increase in our maximum rates, we must negotiate with our principal airline customers the specific rates applicable to each aeronautical activity. As a result, we are not always able to increase prices up to the amount of maximum rates.

International passenger charges are currently dollar-denominated, but are collected in pesos based on the average exchange rate during the month prior to the flight. Domestic passenger charges are peso-denominated. In 2006 and 2007, passenger charges represented approximately 80.0% and 83.2%, respectively, of our aeronautical services revenues and approximately 65.1% and 67.3%, respectively, of our total revenues. Passenger charges vary at each of our airports and are based on the destination of each flight. Because passenger charges for international flights are denominated in U.S. dollars, the value of our revenues from those charges is therefore affected by fluctuations in the value of the U.S. dollar as compared to the peso.

Aircraft Landing Charges

We collect landing charges from carriers for their use of our runways, illumination systems on the runways and other visual landing assistance services. Our landing charges are different for each of our airports and are based on each landing aircraft’s weight (determined as an average of the aircraft’s weight without fuel and maximum takeoff weight), the time of the landing, the origin of the flight and the nationality of the airline or client. In 2006 and 2007, aircraft landing charges represented approximately 6.1% and 4.8%, respectively, of our aeronautical revenues and 4.0 % and 3.9%, respectively, of our total revenues.

Aircraft Parking, Boarding and Unloading Charges

We collect various charges from carriers for the use of our facilities by their aircraft and passengers after landing. We collect aircraft parking charges based on the time an aircraft is at

35

an airport’s gate or parking position. Each of these charges varies based on the time of day or night that the relevant service is provided (with higher fees generally charged during peak usage periods and at night), the aircraft’s maximum takeoff weight, the origin and destination of the flight and the nationality of the airline or client. We collect aircraft parking charges the entire time an aircraft is on our aprons.

Aircraft Long-Term Parking Charges

We collect charges from our carriers for the long-term use of facilities at our airports for aircraft long-term parking that does not involve the loading or unloading of passengers or cargo. These charges are based on the time of day or night the aircraft is parked at our facilities, the length of time the aircraft is parked at our facilities and the nationality of the airline or client. Together with our aircraft parking, boarding and unloading charges described above, in 2006 and 2007, these charges represented approximately 5.3% and 4.1%, respectively, of our aeronautical services revenues and 4.3% and 3.3%, respectively, of our total revenues.

Passenger Walkway Charges

Airlines are also assessed charges for the connection of their aircraft to our terminals through a passenger walkway and for the transportation of passengers between terminals and aircraft via mini-buses and other vehicles. Until March 2005, these charges were based on the amount of time each service was used, the number of these services used, the time of day the services were used, the origin and destination of the flight and the nationality of the airline or client. Since April 1, 2005, charges for use of passenger walkways continue to be assessed as described above, but charges for the transportation of customers between terminals and aircraft via mini-buses and other vehicles have been determined based on the number of trips taken between the terminal and the aircraft. Passenger walkways are only available at our Guadalajara, Tijuana, Puerto Vallarta and Guanajuato international airports. In each of 2006 and 2007, these charges represented approximately 1.1% and 0.8%, respectively, for both years of our aeronautical services revenues and approximately 0.9% and 0.7%, respectively, of our total revenues.

Airport Security Charges

We also assess an airport security charge, which is collected from each airline, based on the number of its departing terminal passengers (excluding infants, diplomats and transit passengers), for use of our x-ray equipment, metal detectors and other security equipment and personnel. These charges are based on the time of day the services are used, the number of departing passengers and the destination of the flight. We provide airport security services at our airports directly. In each of 2006 and 2007, these charges represented approximately 1.4% in both years of our aeronautical services revenues and approximately 1.1% in both years of our total revenues.

The Mexican Bureau of Civil Aviation, Mexico’s federal authority on aviation, and the Office of Public Security (Secretaría de Seguridad Pública) issue guidelines for airport security in Mexico. In response to the September 11, 2001 terrorist attacks in the United States, we took additional steps to increase security at our airports. At the request of the Federal Aviation

36

Authority of the United States, the Mexican Bureau of Civil Aviation issued directives in October 2001 establishing new rules and procedures to be adopted at our airports. Under these directives, these rules and procedures were implemented immediately and for an indefinite period of time.

To comply with these directives, we reinforced our security by:

• Adding security personnel, some of which is contracted with third-party providers;

• Updating and amending our emergency security and contingency plans and the responsibilities of security personnel relating thereto;

• Establishing security supervision committees at each of our airports;

• Increasing the sensitivity and technology of metal detectors and introducing new procedures for x-ray inspection of hand baggage and screening for explosives;

• Increasing and improving the training of security personnel;

• Coordinating security measures and emergency plans with operators of complementary and commercial services at our airports;

• Implementing a higher-security employee identification system;

• Hiring third-party providers of security equipment installation services;

• Establishing security review procedures at all of our airports; and

• Installing a closed-circuit television security monitoring system at our Guadalajara International Airport, Tijuana International Airport and Puerto Vallarta International Airport.

Several of our airline customers have also contributed to the enhanced security at our airports as they have adopted new procedures and rules issued by the Mexican Bureau of Civil Aviation applicable to airlines. Some measures adopted by the airlines include adding more points for verification of passenger identification, inspecting baggage prior to check-in and reinforcing controls over access to airplanes by various service providers (such as baggage handlers and food service providers). In the future, we hope to reach a global agreement with the airlines regarding the respective responsibilities of them and us for checked baggage screening and the allocation of the cost thereof.

Complementary Services

At each of our airports, we earn revenues from charging access and other fees to third-party providers of baggage handling services, catering services, aircraft maintenance and repair services and fuel services at our airports. These fees are included in the revenues that are regulated under our maximum-rate price regulation system and are determined for each third-party service provider based on a percentage of its total revenues. In 2006 and 2007, revenues

37

from these complementary service fees represented approximately 1.9% of our aeronautical revenues services. We currently maintain contracts with 23 companies that provide the majority of these complementary services at our 12 airports.

Under the Mexican Airport Law, we are required to provide complementary services at each of our airports if there are no third parties providing such services. For example, SEAT, which is controlled by Aeroméxico and Mexicana through a joint venture, currently provides the majority of the baggage handling services at our airports. If the third parties currently providing these services ceased to do so, we would be required to provide these services or find other third parties to provide such services.

The Mexican Airport and Auxiliary Services Agency (Aeropuertos y Servicios Auxiliares) maintains an exclusive contract to sell fuel at all of our airports and we charge the Mexican Airport and Auxiliary Services Agency a nominal access fee. The Mexican Airport and Auxiliary Services Agency in turn is required to purchase all of its fuel from Petróleos Mexicanos, or PEMEX. In the event that the Mexican government privatizes fuel supply activities in the future, the terms of our concessions provide that it will do so through a competitive bidding process.

Leasing of Space to Airlines

In addition, we derive regulated revenues from leasing to airlines space in our airports that is necessary for their operations, such as ticket counters, monitors and back offices. In 2006 and 2007, leasing of space to airlines represented approximately 4.1% and 3.8%, respectively, of our aeronautical services revenues and approximately 3.4% and 3.1%, respectively, of our total revenues.

Cargo Handling

In 2007, our 12 airports handled approximately 160,819 thousand metric tons of cargo. Guadalajara International Airport represents the most significant portion of our cargo volume, accounting for approximately 77.3% of the cargo handled by our 12 airports in 2007. Increases in our cargo volume are beneficial to us for purposes of maximum rate calculations, as cargo increases the number of our workload units.

Cargo-related revenues include revenues from the leasing of space in our airports to handling agents and shippers, landing fees for each arriving aircraft carrying cargo and a portion of the revenues derived from other complementary services for each workload unit of cargo. Cargo-related revenues are largely regulated and therefore subject to maximum rates applicable to regulated revenues sources.

Revenues from cargo handling in our airports historically have represented a negligible portion of our total revenues, but we believe that Mexico has significant potential for growth in the volume of cargo transported by air. The Ministry of Communications and Transportation estimates that less than 0.2% of the cargo transported in Mexico in 2006 was transported by air, which we believe to be substantially lower than the comparable percentage in many other countries. A substantial portion of cargo originating in the United States and destined for Latin America is currently handled in the Miami and Los Angeles international airports, and we believe that a portion of this cargo could instead be routed more efficiently through our Guadalajara International Airport or our Tijuana International Airport.

38

Permanent Ground Transportation

We receive revenues from ground transportation vehicles and taxi companies who pay an access fee to operate on our airports’ premises. Our revenues from providers of ground transport services deemed “permanent” under applicable Mexican law, such as access fees charged to taxis, are subject to price regulation.

Non-aeronautical Services

General

Non-aeronautical services historically have generated a significantly smaller portion of our revenues as compared to aeronautical services, although the contribution to our total revenues from non-aeronautical services has increased in recent years from approximately 15.0% in 2003 to approximately 19.1% in 2007 (revenues from non-aeronautical services consisted of approximately 18.6% in 2006). We estimate that this contribution will continue to increase because we continue to expand commercial spaces inside our terminals and we are additionally beginning to focus on developing commercial spaces outside of our terminal buildings. Our revenues from non-aeronautical services are principally derived from commercial activities.

None of our revenues from non-aeronautical services are regulated under our maximum-rate price regulation system.

Revenues from Commercial Activities

Leading privatized airports typically generate a significant portion of their revenues from commercial activities. An airport’s revenues from commercial activities are largely dependent on passenger traffic, its passengers’ level of spending, its terminal design, the mix of commercial tenants and how fees are charged to businesses operating in the commercial area of the airport. Revenues from commercial activities depend substantially on the percentage of traffic represented by international passengers, who tend to spend greater amounts at our airports, particularly on duty-free items. The contribution to our total revenues of our commercial activities has increased significantly, from approximately 15.0% in 2003 to approximately 19.1% in 2007.

We currently have the following types of commercial activities in each of our airports:

• Parking facilities—On December 31, 2007, we operated the car parking facilities at all of our airports except Tijuana International Airport. Starting January 12, 2008, we began operating the Tijuana International Airport parking lot. Our main car parking facility is at the Guadalajara International Airport, and it is managed through a service contract pursuant to which we pay 22% of the revenues of the parking facility for its operation and maintenance by a third party. At the other ten airports at which we operated parking facilities during 2007, we operated them directly. The

39

parking facilities at our Tijuana International Airport were operated during 2007 by a third party pursuant to a long-term lease agreement signed with them by our predecessor, the Mexican Airport and Auxiliary Services Agency, prior to the granting of our concessions. As previously mentioned, we resumed operation of the Tijuana parking facility at the beginning of 2008, which should help us to increase our commercial revenues in the immediate future. Revenues from parking facilities at our airports currently are not regulated under our maximum rates, although they could become regulated (out of our maximum rates) upon a finding by the Mexican Antitrust Commission (Comisión Federal de Competencia) that there are no competing alternatives for such parking.

• Leasing of space—Revenues that we derive from the leasing of space in our terminals to airlines and complementary service providers for certain non-essential activities such as first class/VIP lounges are not subject to price regulation under our maximum rates and are classified by us as non-aeronautical commercial activities.

• Retail stores—In recent years we have completed renovation projects to improve the product mix of retail stores in the commercial areas at our Guadalajara, Puerto Vallarta, Los Cabos, Guanajuato, Tijuana, Manzanillo, Morelia and La Paz international airports. We intend to implement similar projects at all of our airports.

• Food and beverage services—In recent years we have completed “clean up” projects with respect to our restaurant and bar leases, in order to bring in providers with recognizable brand names more likely to increase consumer traffic in our commercial areas.

• Car rentals—We have recently remodeled the areas used by car rental agencies to which we lease space at our airports and have sought to bring in a greater percentage of internationally known name-brand car rental providers.

• Time-share marketing and sales—We receive revenues from time-share developers to which we rent space in our airports for the purpose of marketing and sales of time-share units.

• Duty-free stores—We currently have duty-free stores at four of our 12 airports. These stores are most lucrative at our Puerto Vallarta, Los Cabos and Guadalajara airports, where we have a greater number of international passengers. At the end of 2007, in Puerto Vallarta, we leased the first duty-free store in our airports that is fully integrated with the passenger flows, which means that every passenger departing from the new international building must enter the store, as it is part of the existing hall that connects to the gates area.

• Advertising—We currently have a contract with one of the leading advertising agencies in Mexico, pursuant to which we have developed a greater number of, and more strategically located, billboards and other advertising spaces at our airports.

• Communications—We have consolidated all of the telephone and Internet service at our airports with one provider. All of our airports offer wireless Internet service.

40

• Financial services—In recent years we have expanded and modernized the spaces we lease to financial services providers such as currency exchange bureaus, and have additionally improved our contracts with several of the financial services providers at our airports to provide for access fees based on a percentage of the revenues recorded by those providers rather than fixed yearly fees.

• Ground transportation—Our revenues from providers of ground transportation services deemed “non-permanent” under applicable Mexican law, such as access fees charged to charter buses, are not subject to price regulation under our maximum rates and are classified by us as non-aeronautical commercial activities.

Domestic passengers represented approximately 66.8% of our terminal passenger traffic in 2007. In addition, we estimate that a significant minority of our international passengers are lower-income Mexicans traveling to or from the United States. We believe that the spending habits of these Mexican international passengers are more similar to the spending habits of our domestic passengers, who generally purchase fewer products than other international passengers.

Recent Expansion and Development of Commercial Areas

Leading privatized airports typically generate a greater portion of their revenues from commercial activities than we currently do. We estimate that, prior to 2002, revenues from commercial activities in our airports generally accounted for less than 12% of the total revenues generated by our airports. In contrast, we believe that revenues from commercial activities account for up to 40% or more of the consolidated revenues of many leading privatized airports. While we expect aeronautical revenues to continue to represent a substantial majority of our future revenues, we expect that the future growth of our revenues from commercial activities will exceed the growth of our aeronautical revenues. As the main part of our business strategy, since we took over control of our airports, we have made it a priority to increase our revenues from commercial activities in our airports, from a combination of:

• Redesigning and expanding the space available in our airport terminals allocated to commercial activities.

In order to increase our revenues from commercial activities, we have focused on expanding and redesigning the layout of certain terminals in our airports to allow for the inclusion of more commercial businesses, as well as to redirect the flow of passengers through our airports, increasing their exposure to the commercial businesses that are operating at our airports.

In the second half of 2007 we added approximately 1,500 square meters of commercial space at the new international building in Puerto Vallarta, including two stores fully integrated with the passenger flows. One is a duty-free store and the other is the first convenience store in Mexico which all passengers must pass through in order to reach their gate. We also opened commercial areas at the Terminal 2 building at the Guadalajara airport. During the second half of 2007, we prepared two ambitious commercial redesign projects that will be fully operational at the end of 2008 at the Los Cabos Terminal 1 and in the domestic departures area in

41

Guadalajara. During the second half of 2008 we expect to complete the expansion of the parking building in Guadalajara adding approximately 1,500 additional spaces to the currently available 1,500 spaces.

• Renegotiating agreements with terminal tenants to be more consistent with market practices.

We have also continued improving our lease arrangements with existing tenants through the usage of royalty-based lease contracts, whereby lease amounts are based on tenants’ revenues, subject to minimum fixed amounts related to the square footage. We estimate that approximately 89% of our commercial agreements could be arranged as royalty-based contracts based on the nature of our tenants’ operations. Of those, we estimate that we have updated and signed approximately 95% of the agreements. In 2001, less than 5% of our lease contracts provided for royalty payments.

• Recovering the rights to several retail and car parking businesses at our airports previously operated by third parties.

Prior to 1999, our predecessor entered into several contracts with third-party operators to develop new space and modernize existing space at our 12 airports. Several of these contracts were long-term lease agreements pursuant to which the third-party service provider, in exchange for assuming all risks during the construction and modernization phase of each development project, acquired the exclusive right to operate the new commercial areas once developed. Many of the most lucrative commercial areas within our principal airports were leased by our predecessor to third parties on a long-term basis.

In some cases these long-term leases also gave the third-party operators the right to operate not only commercial activities, but also passenger walkways, transportation and other activities in the commercial areas subject to the leases. We acquired our concessions from our predecessor subject to these long-term lease obligations and have sought to recover the third parties’ lease rights. In recent years we have recovered, by compensating leaseholders for early termination of their leases, several significant leases previously held by third parties who managed our commercial areas and received all revenues from the operations in those areas. We now manage several of those areas directly and have thereby increased our revenues from commercial activities.

At December 31, 2007, there were only two material commercial activities at our airports that remained subject to third-party leases under which we receive nominal or no revenue:

Hotel at Guadalajara International Airport.Coco Club was granted the right by the Mexican Airport and Auxiliary Services Agency to operate the following commercial space at our Guadalajara International Airport in exchange for the construction and remodeling of certain commercial areas and infrastructure at the airport: (i) the commercial space located in the hallway leading to the gate area for domestic flights, (ii) the majority of the commercial space in the gate area itself , (iii) the commercial space in the bridge connecting the airport to the airport hotel and (iv) the hotel itself. In September 1998, Coco Club transferred all of these rights to a

42

third party except for the right to operate the hotel for a period of 15 years from March 1993 in exchange for its obligation to construct such hotel. In May 2004, we recovered the right to operate the commercial areas previously operated by the third party that received its rights from Coco Club. Coco Club has the right to renew the contract and continue operating the hotel for another 15-year period from March 2008.

Car parking at Tijuana International Airport. Constructora Comar, S.A. de C.V., or Comar, was granted the right by the Mexican Airport and Auxiliary Services Agency to construct and operate five-floor parking facilities within our Tijuana International Airport. On January 12, 2008, we assumed the right to operate this parking facility.

Marketing Activities

Our marketing activities focus, with respect to aeronautical services, on participation in business conferences organized by the International Air Transport Association (IATA), including the annual “Schedules” and “Commercial Strategy” conferences. These conferences provide a forum for the exchange of information relating to airlines’ decisions about changes in routes and flights. For leasing of properties and related non-aeronautical services, we principally rely on advertising through traditional local distribution channels, including newspapers.

Our Airports

In 2007, our airports served a total of approximately 23.6 million terminal passengers. In 2007, our two principal airports that serve important metropolitan areas, Guadalajara International Airport and Tijuana International Airport, together represented approximately 51.2% of our total terminal passenger traffic. Puerto Vallarta International Airport and Los Cabos International Airport, our main airports serving popular tourist destinations, together accounted for approximately 25.6% of our total terminal passenger traffic in 2007. Hermosillo International Airport, which is our largest airport serving a mid-sized city, accounted for approximately 5.7% of our total terminal passenger traffic in 2007.

All of our airports are designated as international airports under applicable Mexican law, meaning that they are equipped to receive international flights and maintain customs and immigration facilities operated by the Mexican government.

Guadalajara International Airport

The Guadalajara International Airport is our most important airport in terms of passenger traffic, air traffic movements and contribution to revenues. In 2007, the Guadalajara International Airport was the third busiest in Mexico in terms of commercial aviation passenger traffic according to the Mexican Airport and Auxiliary Services Agency. In 2007, the Guadalajara International Airport accounted for approximately 31.1% of our terminal passenger traffic.

In 2007, a total of 7.3 million terminal passengers were served by Guadalajara International Airport. Of the terminal passengers in 2007, 68.8% were domestic and 31.2% were international passengers. Of the airport’s international passengers, we estimate that a significant portion are Mexicans living in the United States visiting Guadalajara. This airport also serves many business travelers traveling to and from Guadalajara. Because the airport’s passengers are predominantly domestic, the airport’s passenger traffic and results of operations are affected by Mexican economic conditions.

47

A total of 22 airlines operate at the airport, the principal ones of which are Aeroméxico, Mexicana and Aerocalifornia. The main non-Mexican airlines operating at the airport are Continental Airlines, American Airlines and Delta Airlines. Airlines operating at the airport reach 49 destinations. Of these destinations, Mexico City, Tijuana and Los Angeles are the most popular. Since 2005, we have had agreements with three of Mexico’s low-cost Mexican carriers for their operations.

Guadalajara International Airport is located approximately 20 kilometers from the city of Guadalajara, which has a population (including its suburbs) of approximately 5 million inhabitants. Guadalajara is Mexico’s second largest city in terms of population, as well as the capital of the state of Jalisco, the country’s fourth largest state in terms of population. As a major hub for the Mexican national highway system, the city of Guadalajara is an important center for both ground and air transportation. Other major cities in the state of Jalisco include Puerto Vallarta and Lagos de Moreno. Jalisco is an important agricultural producer, making Guadalajara an important center for agricultural commerce. The state is an important contributor to Mexico’smaquiladora industry, most notably in the electronic, computer equipment and clothing industries. The maquiladora industry in Jalisco grew significantly in the 1990’s asmaquiladoras moved away from the U.S.-Mexico border seeking lower labor costs and a more diverse labor pool.

Guadalajara International Airport operates 24 hours daily. The airport has two operating runways, one with a length of 4,000 meters, and the other with a length of 1,770 meters, as well as a full parallel taxiway. The runway capacity at this airport is 39 air traffic movements per hour. The airport also has an instrument landing system (ILS) that assists pilots in poor weather. The airport’s facilities include a main commercial terminal with a large parking facility and a general aviation building. The airport’s main commercial terminal has a total area of approximately 24,850 square meters, as well as parking facilities consisting of an additional 46,000 square meters. The general aviation building has an additional 1,825 square meters. The main commercial terminal has 18 gates and 23 remote boarding positions. Of the 18 gates, eight serve international flights and ten serve domestic flights. Of the international gates, three have air bridges, and of the domestic gates, five have air bridges. Additionally there are eleven remote positions used for the regional flights commonly used by Alma and Aeroméxico Connect.

Until May 31, 2004, the most lucrative commercial space (comprising approximately 1,300 square meters) in and leading to the domestic departure area was operated by a third party under a long-term agreement scheduled to expire in 2010. On May 31, 2004, we recovered the rights to operate that commercial space as of June 1, 2004. As part of our business strategy, we intend to renovate this area and better integrate it within the other commercial space at the airport. The airport has an onsite hotel operated by a third party from which we derive no revenues.

Between 2005 and 2006 we took significant steps to modernize and expand the Guadalajara International Airport in order to improve its operations and image. During this

48

period we expanded the commercial space in this airport by 1,210 square meters in the international gate area. In addition, these steps have included the improvement of the airport’s runways and platforms, an increase in the number of remote boarding positions, the installation of an improved computer system and expansion of the main commercial terminal, including the installation and/or modernization of air bridges, the baggage claim area, ticket counters, restrooms, hallways and gate areas. In addition, between 2007 and 2009 we expect to complete the expansion of the international baggage claim area and the expansion of the domestic and international gate areas and the international arrival area by a total of 7,067 square meters and to remodel an additional 2,120 square meters in these areas. Also, the expansion of the main parking facilities, expected to open during the second half of 2008, is currently underway. After the renovations, approximately 2,000 square meters of these areas will be devoted to commercial activities.

Tijuana International Airport

Tijuana International Airport is our second most important airport in terms of passenger traffic, the fourth in contribution to revenues and the second in air traffic movements. In 2007, Tijuana International Airport was the fifth busiest airport in Mexico in terms of commercial aviation traffic according to the Mexican Airport and Auxiliary Services Agency. In 2007, it accounted for approximately 20.1% of our terminal passenger traffic.

In 2007, Tijuana International Airport served a total of 4.7 million terminal passengers. We estimate that almost all of the passengers were domestic passengers. Since Tijuana is located near the Mexico-U.S. border and is therefore a popular entry point to the United States, a majority of the airport’s passengers consists of Mexican migrant workers traveling to Tijuana in order to seek work in the United States. Accordingly, the airport’s passenger traffic and results of operations are affected by Mexican and U.S. economic conditions. A highway connecting the city of Tijuana to the airport also extends directly to the U.S.-Mexico border crossing, providing convenient access to San Diego, California (which is located approximately 30 kilometers) from Tijuana International Airport and other areas of southern California, particularly Los Angeles.

Tijuana International Airport serves the city of Tijuana and surrounding areas in the State of Baja California, including the municipalities of Ensenada, Tecate and Rosarito. With a population of approximately 1.5 million, Tijuana is the largest city in the state. Currently, in terms of population, the state of Baja California is the second largestmaquiladora center in Mexico according to the Mexican National Institute of Statistics.

A total of ten airlines operate at the airport, the principal ones of which are Aeroméxico and Aviacsa. Airlines operating at this airport provide service to 30 destinations. Of these destinations, Mexico City, Guadalajara, Guanajuato and Morelia are the most popular. In addition, Aeroméxico began flying twice weekly from Tijuana to Tokyo. By the end of 2007, four low-cost carriers were operating service to and from Tijuana, with 24 routes in total.

Tijuana International Airport currently operates 17 hours daily between the hours of 7:00 a.m. and 12:00 a.m. However, it is equipped to operate 24 hours daily if necessary and we double our passenger charges and fees for other aeronautical services provided outside normal business hours (07:00 a.m. to 12:00 a.m.). The airport has one runway with a length of 2,960

49

meters and a full parallel taxiway. The runway capacity at this airport is 30 air traffic movements per hour. The airport also has an instrument landing system (ILS) that assists pilots in poor weather. It has 22 gates serving both domestic and international travelers and eight remote boarding positions. Of the 22 gates, ten have air bridges.

In 2007, approximately 16,990 metric tons of cargo were transported through the airport.

A portion of the land comprising Tijuana International Airport was expropriated by the Mexican federal government in 1970 pursuant to its power of eminent domain and is subject to certain legal proceedings by its former landholders. For a description of these legal proceedings and their potential impact on our operations, see “Item 3, Key Information—Risk Factors—Risks Related to Our Operations—Actions by the former holders of land comprising Tijuana International Airport may limit our ability to expand the airport and may disrupt its operations.”

Puerto Vallarta International Airport

Puerto Vallarta International Airport is our third most important airport in terms of passenger traffic and air traffic movements and third in terms of contribution to revenues. In 2007, Puerto Vallarta International Airport was the seventh busiest airport in Mexico in terms of commercial aviation passenger traffic according to the Mexican Airport and Auxiliary Services Agency. In 2007, it accounted for approximately 13.3% of our terminal passenger traffic.

In 2007, 3.1 million terminal passengers traveled through Puerto Vallarta International Airport. We estimate that 73.1% of these terminal passengers were international passengers and 26.9% were domestic passengers. The airport primarily serves foreign tourists and is a popular tourist destination in Mexico.

A total of 19 regular and 14 charter airlines operate at the airport, the principal ones of which are Alaska, Aeroméxico and Mexicana. Airlines operating at this airport reach 38 destinations. Of these destinations, the most popular ones are Los Angeles and destinations in Canada. We are currently engaged in discussions with a U.S. carrier regarding the addition of two routes between Puerto Vallarta and the United States.

Puerto Vallarta International Airport is located on the Pacific coast in the state of Jalisco. Puerto Vallarta’s tourist attractions include the natural beauty of the Bay of Banderas, the area’s many beaches and abundant marine wildlife. Puerto Vallarta is a mature tourist destination, and the completion of new resort areas including hotels and golf courses in the areas known as Nuevo Vallarta and Punta Mita is expected to bring more tourists to the area in subsequent years. We believe that a significant portion of the tourists visiting Puerto Vallarta consist of time-share owners who make frequent trips to the area.

Puerto Vallarta International Airport operates 24 hours daily. The airport has one runway with a length of 3,100 meters as well as a parallel taxiway. The runway capacity at this airport is 30 air traffic movements per hour. This airport has one main commercial terminal, a fixed-base operation, or FBO, terminal and a general aviation building. The airport has fifteen gates serving domestic and international flights, ten remote boarding positions and seven air bridges.

Until May 31, 2004, the right to operate all of the commercial space (comprising approximately 2,500 square meters) and the mini-buses and other vehicles and services, as well as the right to collect access fees from ground transportation providers in the Puerto Vallarta International Airport belonged to a third party pursuant to a long-term lease. On June 1, 2004, we recovered the rights to operate the commercial space and transportation and to collect access fees from providers of ground transportation.

During 2005 and at the beginning of 2006, the terminal building of the Puerto Vallarta International Airport was improved through expansion and remodeling projects. The projects included the construction of a new building that will house the documentation areas of the regular and charter airlines, the expansion of baggage claim areas (particularly for international arrivals), the expansion of the immigration area and the expansion of the final waiting areas, as well as some improvements, for a total of 8,140 square meters of total expansions. Approximately 1,100 square meters of this expansion will be used for commercial spaces. Additionally, we built a 13,400 square meter satellite building during 2007, which became operational in December 2007.

Los Cabos International Airport

Los Cabos International Airport is our fourth most important airport in terms of passenger traffic, our fifth most important airport in terms of air traffic movements and our second most important airport in terms of contribution to revenues.

Visitors to this area are generally affluent, and include golfers who enjoy world-class courses, as well as sports fishing and scuba diving enthusiasts who are drawn by the rich marine life in the region’s coastal waters. According to Mexico’s Ministry of Tourism (Secretaría de Turismo), hotel capacity in Los Cabos reached 5,722 rooms in 2003, 9,841 rooms in 2004, and 10,069 rooms in 2005. A growing percentage of visitors to Los Cabos consists of recurring visitors as the popularity and availability of time-shares in the area has increased over recent years.

In 2007, Hermosillo International Airport served approximately 1.3 million terminal passengers, and approximately 93.0% of those terminal passengers were domestic. Many of the airport’s passengers use the airport as a hub for connecting flights between other Mexican cities, particularly Mexico City, Tijuana, Guadalajara and Monterrey. Because the airport’s passengers are predominantly domestic, the airport’s passenger traffic and results of operations are affected by Mexican economic conditions.

A total of nine airlines operate at the airport, the principal ones of which are Aeroméxico, Aeroméxico Connect and Aerocalifornia. Airlines operating at this airport provide service to 18 destinations. Of these destinations, Mexico City, Tijuana and Guadalajara are the most popular.

Principal Customers

Principal Aeronautical Services Customers

Airline Customers

As of December 31, 2007, 19 international airlines (considering all charter airlines as one client since we manage them through a single representative that is our actual client), and 16 Mexican airlines operated flights at our 12 airports. Aeroméxico operates the most flights at our airports, with Mexicana providing the second highest number of flights. In 2007, revenues from Aeroméxico totaled Ps. 546.7 million, of which Ps. 469.5 million was derived from passenger charges, while revenues from Mexicana were Ps. 428.7million, of which Ps. 406.0 million was derived from passenger charges, representing 15.3% and 12.0%, respectively, of our total revenues for 2007. In addition to passenger charges, revenues are earned from landing charges, aircraft parking charges and the leasing of space to these airlines.

Until 2005 Consorcio Aeroméxico also owned Mexicana and its affiliate Click Mexicana (formerly known as Aerocaribe). On December 20, 2005, Consorcio Aeroméxico sold Mexicana and Click Mexicana to Grupo Posadas, S.A de C.V., the largest hotel operator in Mexico. Aeroméxico and Mexicana also control other airlines operating in our airports, including Aerocozumel and Aeromexpress, as well as the largest provider of baggage and ramp handling services at our airports, Servicios de Apoyo en Tierra, or SEAT, a joint venture between Aeroméxico and Mexicana.

Aeroméxico and Mexicana, along with Aeromar and Aeroméxico Connect, have in the past refused to pay certain increases in our airport service charges. On July 15, 2003, we entered into an agreement with the National Air Transportation Chamber of Commerce and the Ministry of Communications and Transportation pursuant to which we resolved existing disputes with our airlines and established specific prices applicable to those airlines for 2003 and 2004 and a method for retroactively applying those prices from 2000, since these airlines had refused to pay certain of our charges since that year. In March 2005, we entered into a renewal agreement with the National Air Transportation Chamber of Commerce for the years 2005 and 2006. In December 2006, we entered into a renewal agreement with the National Air Transportation Chamber of Commerce for 2007, 2008 and 2009, which also provided for an increase in passenger charges. This renewal agreement is more focused on the support and development of, and increased frequencies of, new routes.

Complementary Services Customers

Our principal complementary services clients are our two principal providers of baggage handling services, Menzies Aviation and SEAT, which provided Ps. 36.4 million of revenues each in the form of access fees in 2007. Although SEAT is the primary provider of complementary services in our airports, under our agreement with the National Air Transportation Chamber of Commerce described above, we earn only nominal revenues from SEAT.

58

Our primary catering clients are Comisariato Gotre, S.A. de C.V. and Aerococina, S.A. de C.V., which provided Ps. 5.2 million and Ps. 5.0 million in revenues in the form of access fees, respectively, in 2007.

Principal Non-aeronautical Services Customers

At December 31, 2007, we were party to approximately 775 contracts with providers of commercial services in the commercial space in our airports, including retail store operators, duty-free store operators, food and beverage providers, financial services providers, car rental companies, telecommunications providers, VIP lounges, advertising, travel agencies and tourist information and promotion services. As a result, our revenues from non-aeronautical services commercial customers are spread across a large number of customers and are therefore not dependent on a limited number of principal customers. In 2007, our largest commercial customers were Operadora Aeroboutiques, S.A. de C.V. (duty-free and convenience stores; Ps. 58.1 million), Unidad de Diseño y Comunicación, S.A. de C.V. (advertising; Ps. 31.6 million), Dufry México (duty-free stores, Ps. 21.3 million), Desarrolladores de los Cabos, S.A. de C.V. (time-share activities, Ps. 16.8 million), Desarrolladores de Baja California Sur, S.A. de C.V. (time-share activities, Ps. 16.7 million), Estrategia Comercializadora del Pacífico, S.A. de C.V. (time-share activities, Ps. 15.6 million). Aerocomidas, S.A. de C.V. (food and beverages, Ps. 12.8 million), Servicios Inmobiliarios Alsea, S.A. de C.V. (food and beverages, Ps. 9.8 million), Comercial Ariete, S.A. de C.V. (car rentals, Ps. 7.4 million) and Teléfonos de México, S.A. de C.V. (public telephones, Ps. 7.2 million).

Seasonality

Our business is subject to seasonal fluctuations. In general, demand for air travel is typically higher during the summer months and during the winter holiday season, particularly in international markets, because there is more vacation travel during these periods. Our results of operations generally reflect this seasonality, but have also been impacted by numerous other factors that are not necessarily seasonal, including economic conditions, war or threat of war, weather, air traffic control delays and general economic conditions, as well as the other factors discussed above. As a result, our results of operations for a quarterly period are not necessarily indicative of results of operations for an entire year, and historical results of operations are not necessarily indicative of future results of operations.

Competition

Excluding our airports servicing tourist destinations, our airports generally are natural monopolies in the geographic areas that they serve and generally do not face significant competition.

However, since our Puerto Vallarta, Los Cabos, La Paz and Manzanillo international airports are substantially dependent on tourists, these airports face competition from competing tourist destinations. We believe that the main competitors to these airports are those airports serving vacation destinations in Mexico, such as Acapulco and Cancún, and abroad such as in Puerto Rico, Florida, Cuba, Jamaica, the Dominican Republic, other Caribbean islands and Central America. In addition, the governor of the state of Quintana Roo has announced that the state is interested in developing a competing airport on the Mayan Riviera.

59

The relative attractiveness of the locations we serve is dependent on many factors, some of which are beyond our control. These factors include the general state of the Mexican economy and the attractiveness of other commercial and industrial centers in Mexico that may affect the attractiveness of Guadalajara, Tijuana and other growing industrial centers in our group, such as Hermosillo, León, Aguascalientes and Mexicali. In addition, with respect to Puerto Vallarta, Los Cabos, La Paz and Manzanillo, these factors include promotional activities and pricing policies of hotel and resort operators, weather conditions, natural disasters (such as hurricanes and earthquakes) and the development of new resorts that may be considered more attractive. There can be no assurance that the locations we serve will continue to attract the same level of passenger traffic in the future.

The Mexican Airport and Auxiliary Services Agency currently operates seven small airports in Mexico’s Pacific and central regions. We believe that these airports collectively account for only a small fraction of the passenger traffic in these regions.

REGULATORY FRAMEWORK

Sources of Regulation

The following are the principal laws, regulations and instruments that govern our business and the operation of our airports:

• the Mexican Airport Law, enacted December 22, 1995;

• the regulations under the Mexican Airport Law (“Reglamento de la Ley de Aeropuertos”), enacted February 17, 2000;

• the Mexican Communications Law (“Ley de Vías Generales de Comunicación”), enacted February 19, 1940;

• the Mexican Civil Aviation Law (“Ley de Aviación Civil”), enacted May 12, 1995;

• the Mexican Federal Duties Law, revised on an annual basis;

• the Mexican National Assets Law (“Ley de Bienes Nacionales”), enacted May 20, 2004; and

• the concessions that entitle our subsidiaries to operate our 12 airports, which were granted on June 29, 1998 and amended on November 15, 1999.

The Mexican Airport Law and the regulations under the Mexican Airport Law establish the general framework regulating the construction, operation, maintenance and development of Mexican airport facilities. The Mexican Airport Law’s stated intent is to promote the expansion, development and modernization of Mexico’s airport infrastructure by encouraging investment and competition.

60

Under the Mexican Airport Law, a concession granted by the Ministry of Communications and Transportation is required to construct, operate, maintain and develop a public service airport in Mexico. A concession generally must be granted pursuant to a public bidding process, except for: (i) concessions granted to (a) entities considered part of “the federal public administration” as defined under Mexican law and (b) any private company the principal stockholder of which is a state or municipal government; (ii) concessions granted to operators of private airports (that have operated privately for five or more years) wishing to begin operating their facilities as public service airports and complying with certain requirements; and (iii) complementary concessions granted to existing concession holders that comply with certain requirements. Complementary concessions may be granted only under certain limited circumstances, such as where an existing concession holder can demonstrate, among other things, that the award of the complementary concession is necessary to satisfy passenger demand. On June 29, 1998, the Ministry of Communications and Transportation granted 12 concessions to operate, maintain and develop the 12 principal airports in Mexico’s Pacific and central regions to our subsidiaries. Because our subsidiaries were considered entities of the federal public administration at the time the concessions were granted, the concessions were awarded without a public bidding process. However, the process of selling 15% of our capital stock to our strategic stockholder pursuant to the privatization process was conducted through a public bidding process. Each of our concessions was amended on November 15, 1999 in order, among other things, to incorporate each airport’s maximum rates and certain other terms as part of the concession.

On February 17, 2000, the regulations under the Mexican Airport Law were issued. We believe we are currently complying with the material requirements of the Mexican Airport Law and its regulations. Non-compliance with these regulations could result in fines or other sanctions being assessed by the Ministry of Communications and Transportation, and are among the violations that could result in termination of a concession if they were to occur three or more times.

On May 20, 2004 a new Mexican National Assets Law was adopted and published in the Mexican Federal Gazette which, among other things, established regulations relating to concessions granted with respect to real property held in the public domain, including the airports that we operate. The new Mexican National Assets Law established new grounds for revocation of concessions for failure to pay applicable taxes, but does not specify which taxed must be paid, including whether certain taxes to municipalities must be paid by a concessionaire.

To the best of our knowledge as of the date hereof, the constitutionality of the new Mexican National Assets Law has not been challenged in Mexico’s court system. If challenged in the future, a court could declare a contested application of a given tax to be void or determine an alternate amount.

Role of the Ministry of Communications and Transportation

The Ministry of Communications and Transportation is the principal regulator of airports in Mexico and is authorized by the Mexican Airport Law to perform the following functions:

In addition, under the Mexican Organic Law of the Federal Public Administration (Ley Orgánica de la Administración Pública Federal), the Mexican Airport Law and the Mexican Civil Aviation Law, the Ministry of Communications and Transportation is required to provide air traffic control, radio assistance and aeronautical communications at Mexico’s airports. The Ministry of Communications and Transportation provides these services through the Mexican Air Traffic Control Authority, which is a division of the Ministry of Communications and Transportation. Since 1978, the Mexican air traffic control authority has provided air traffic control for Mexico’s airports.

New Regulatory Agency

The Ministry of Communications and Transportation has announced that it intends to establish a new regulatory agency. This new agency is expected to be authorized to monitor our activities and those of the other airport groups, enforce applicable regulations, propose amendments to concessions, set maximum rates, resolve disputes between concession holders and airport users (such as airlines) and collect and distribute information relating to the airport sector. The proposal made in Mexico’s Congress in October 2007 to amend the Mexican Airport Law would establish such an agency. However, this initiative has not been approved, and no date for the establishment of this new regulatory agency has been publicly announced. Similarly, a recent bill in Mexico’s Congress proposes to establish a Federal Airport Services Commission.

Concession Tax

Under the Mexican Federal Duties Law, each of our subsidiary concession holders is required to pay the Mexican government a concession tax based on its gross annual revenues from the use of public domain assets pursuant to the terms of its concession. Currently, this concession tax is set at a rate of 5% and may be revised annually by the Mexican Congress. Our concessions provide that we may request an amendment of our maximum rates if there is a change in this concession tax.

Scope of Concessions

We hold concessions granted to us by the Mexican government to use, operate, maintain and develop 12 airports in the Pacific and central regions of Mexico in accordance with the Mexican Airport Law. As authorized under the Mexican Airport Law, each of the concessions is held by our subsidiaries for an initial 50-year term, each of which terms began on November 1, 1998. This initial term of each of our concessions may be renewed for one or more terms for up to an additional 50 years, subject to the concession holder’s acceptance of any new conditions imposed by the Ministry of Communications and Transportation and to its compliance with the terms of its concession. Each of the concessions held by our subsidiary concession holders allows the relevant concession holder, during the term of the concession, to: (i) operate, maintain and develop its airport and carry out any necessary construction in order to render airport, complementary and commercial services as provided under the Mexican Airport Law and the regulations thereunder; and (ii) use and develop the assets that comprise the airport that is the subject of the concession (consisting of the airport’s real estate and improvements but excluding assets used in connection with fuel supply and storage). These assets are government-owned assets, subject to the Mexican National Assets Law. Upon expiration of a concession, these assets, together with any improvements thereto, automatically revert to the Mexican government.

Concession holders are required to provide airport security, which must include contingent and emergency plans in accordance with the regulations under the Mexican Airport Law. The security regulations must be implemented in accordance with the requirements set forth in the National Program for Airport Security (Plan Nacional de Seguridad Aeroportuaria). In addition, the regulations pertaining to the Mexican Airport Law specify that an airport

63

concession holder is responsible for inspecting passengers and their carry-on baggage before they approach the departure gates, and specify that the transporting airline is responsible for the inspection of checked baggage and cargo. If public order or national security is endangered, the competent federal authorities are authorized to act to protect the safety of aircraft, passengers, cargo, mail, installations and equipment.

In 2005, the Mexican government issued a policy letter calling for all checked baggage on international commercial flights beginning in January 2006, and on domestic commercial flights beginning in July 2006, to undergo a new comprehensive screening process. Because of uncertainty over the policy letter’s implementation, the new screening process has been delayed. In particular, the policy letter does not specify which parties should bear responsibility for the new screening process. Although the Mexican Airport Law clearly specifies that airlines bear the responsibility for baggage screening, the fact that the policy letter is silent as to responsibility has caused some of our airline customers to contend that the policy letter’s intent is for airport concessionaires, such as us, to bear responsibility for the new screening process. In addition, certain questions have been raised regarding the constitutionality of the new screening process (in particular, as regards searches outside of the presence of the owners of baggage). The Mexican Bureau of Civil Aviation is expected to issue regulations implementing the policy letter, but these may not address the questions of responsibility and constitutionality that have been raised. We maintain that the new policy will not be implemented at our airports until we enter into a written agreement with our airline customers regarding the allocation of cost and responsibility. The new process is expected to require the installation of new screening equipment and that baggage be checked manually if the equipment signals the potential presence of prohibited items.

The shares of a concession holder and the rights under a concession may be subject to a lien only with the approval of the Ministry of Communications and Transportation. No agreement documenting liens approved by the Ministry of Communications and Transportation may allow the beneficiary of a pledge to become a concession holder under any circumstances.

A concession holder may not assign any of its rights or obligations under its concession without the authorization of the Ministry of Communications and Transportation. The Ministry of Communications and Transportation is authorized to consent to an assignment only if the proposed assignee satisfies the requirements to be a concession holder under the Mexican Airport Law, undertakes to comply with the obligations under the relevant concession and agrees to any other conditions that the Ministry of Communications and Transportation may require.

General Obligations of Concession Holders

The concessions impose certain obligations on the concession holders, including, among others, (i) the obligation to pay the concession tax described above, (ii) the obligation to deliver concession services in a continuous, public and non-discriminatory manner, (iii) the obligation to maintain the airports in good working condition and (iv) the obligation to make investments with respect to the infrastructure and equipment in accordance with the master development programs and the concessions.

64

Each concession holder and any third party providing services at an airport is required to carry insurance in specified amounts and covering specified risks, such as damage to persons and property at the airport, in each case as specified by the Ministry of Communications and Transportation. To date, the Ministry of Communications and Transportation has not specified the required amounts of insurance. We cannot assure you that we will not be required to obtain additional insurance once these amounts are specified.

We and our subsidiary concession holders are jointly and severally liable to the Ministry of Communications and Transportation for the performance of all obligations under the concessions held by our subsidiaries. Each of our subsidiary concession holders is responsible for the performance of the obligations set forth in its concession and in the master development programs, including the obligations arising from third-party contracts, as well as for any damages to the Mexican government-owned assets that they use and to third-party airport users. In the event of a breach of the concession held by any one of our subsidiaries, the Ministry of Communications and Transportation is entitled to revoke the concessions held by all of our subsidiaries.

Substantially all of the contracts entered into prior to August 25, 1999 by the Mexican Airport and Auxiliary Services Agency with respect to each of our airports were assigned to the relevant concession holder for each airport. As part of this assignment, each concession holder agreed to indemnify the Mexican Airport and Auxiliary Services Agency for any loss suffered by the Mexican Airport and Auxiliary Services Agency due to the concession holder’s breach of its obligations under an assigned agreement.

Classification of Services Provided at Airports

The Mexican Airport Law and the regulations thereunder classify the services that may be rendered at an airport into the following three categories:

• Airport Services. Airport services may be rendered only by the holder of a concession or a third party that has entered into an agreement with the concession holder to provide such services. These services include the following:

• The use of airport runways, taxiways and aprons for landing, aircraft parking and departure;

• the use of hangars, passenger walkways, transport buses and car parking facilities;

• the provision of airport security services, rescue and firefighting services, ground traffic control, lighting and visual aids;

• the general use of terminal space and other infrastructure by aircraft, passengers and cargo; and

• the provision of access to an airport to third parties providing complementary services (as defined in the Mexican Airport Law) and third parties providing permanent ground transportation services (such as taxis).

65

• Complementary Services. Complementary services may be rendered by an airline, by the airport operator or by a third party under agreements with airlines and the airport operator. These services include: ramp and handling services, passenger check-in, aircraft security, catering, cleaning, maintenance, repair and fuel supply and related activities that provide support to air carriers.

• Commercial Services. Commercial services are services that are not considered essential to the operation of an airport or aircraft, and include, among other things, retailers, restaurants, banks and advertisers to which we lease space.

A third party rendering airport, complementary or commercial services is required to do so pursuant to a written agreement with the relevant concession holder. We have not entered into any agreement with a third party with respect to the provision of airport services as we provide these services ourselves. All agreements relating to airport or complementary services are required to be approved by the Ministry of Communications and Transportation. The Mexican Airport Law provides that the concession holder is jointly liable with these third parties for compliance with the terms of the relevant concession with respect to the services provided by such third parties. All third-party service providers are required to be corporations incorporated under Mexican law.

Airport and complementary services are required to be provided to all users in a uniform and regular manner, without discrimination as to quality, access or price. Concession holders are required to provide airport and complementary services on a priority basis to military aircraft, disaster support aircraft and aircraft experiencing emergencies. Airport and complementary services are required to be provided at no cost to military aircraft and aircraft performing national security activities. The concession holders have not and do not provide complementary services as these services are provided by third parties.

In the event offorce majeure, the Ministry of Communications and Transportation may impose additional regulations governing the provision of services at airports, but only to the extent necessary to address theforce majeureevent. The Mexican Airport Law allows the airport administrator appointed by a concession holder to suspend the provision of airport services in the event offorce majeure.

A concession holder is also required to allow for a competitive market for complementary services. A concession holder may only limit the number of providers of complementary services in its airport due to space, efficiency and safety considerations. If the number of complementary service providers must be limited due to these considerations, contracts for the provision of complementary services must be awarded through competitive bidding processes.

Master Development Programs

Each concession holder is required to submit to the Ministry of Communications and Transportation a master development program describing, among other things, the concession holder’s construction and maintenance plans.

66

Each master development program is required to be updated every five years and resubmitted for approval to the Ministry of Communications and Transportation. Upon such approval, the master development program is deemed to constitute a part of the relevant concession. Any major construction, renovation or expansion of an airport may only be made pursuant to a concession holder’s master development program or upon approval by the Ministry of Communications and Transportation. Information required to be presented in the master development program includes:

• airport growth and development expectations;

• 15-year projections for air traffic demand (including passenger, cargo and operations);

• construction, conservation, maintenance, expansion and modernization programs for infrastructure, facilities and equipment;

• a binding five-year detailed investment program and planned major investments for the following ten years;

• descriptive airport plans specifying the distinct uses for the corresponding airport areas;

• any financing sources; and

• environmental protection measures.

Each concession provides for a 24-month period for the preparation and submission of the concession holder’s master development program, and requires the concession holder to engage recognized independent consultants to conduct polls among airport users with respect to current and expected quality standards, and to prepare air traffic projections and assess investment requirements. The concession holder must submit a draft of the master development program to an operations committee (Comité de Operación y Horarios),composed of each of the airport’s principal users, for their review and comments six months prior to its submission for approval to the Ministry of Communications and Transportation. Further, the concession holder must submit, six months prior to the expiration of the five-year term, the new master development program to the Ministry of Communications and Transportation. The Ministry of Communications and Transportation may request additional information or clarification as well as seek further comments from airport users. The Ministry of Defense (Secretaría de Defensa Nacional) may also opine on the master development programs.

Any major construction project, renovation or expansion relating to an airport can only be done pursuant to the master development program of the concession holder or with the approval of the Ministry of Communications and Transportation. We are required to spend the full amounts set forth in each investment program under our master development programs.

Changes to a master development program including the related investment program require the approval of the Ministry of Communications and Transportation, except for emergency repairs and minor works that do not adversely affect an airport’s operations.

67

In December 2004, the Ministry of Communications and Transportation approved the master development programs for each of our subsidiary concession holders for the 2005 to 2009 period. We determined to allocate a majority of our investments for the 2005-to-2009 period to our five largest airports.

Our master development programs are approved by the Ministry of Communications and Transportation for periods of five years, as stated in our concessions. We are required to comply with the five-year-period investment obligations under master development programs, and the Ministry of Communications and Transportation may apply sanctions if we do not so comply. Recently the Ministry of Communications and Transportation has reviewed our compliance on an annual basis. The Ministry of Communications and Transportation may choose to do this revision officially and apply sanctions on an annual basis if it determines that we have failed in our investment obligations.

Aeronautical Services Regulation

The Mexican Airport Law directs the Ministry of Communications and Transportation to establish price regulations for services for which there is no competitive market, as determined by the Mexican Antitrust Commission. In 1999, the Mexican Antitrust Commission issued a ruling stating that competitive markets generally do not exist for airport services and airport access provided to third parties rendering complementary services. This ruling authorized the Ministry of Communications and Transportation to establish regulations governing the prices that may be charged for airport services and access fees that may be charged to third parties rendering complementary services in our airports. On November 15, 1999, a new regulation, the Rate Regulation (Regulación Tarifaria), was incorporated within the terms of each of our concessions. This regulation provides a framework for the setting by the Ministry of Communications and Transportation of five-year maximum rates.

Regulated Revenues

The majority of our revenues are derived from providing aeronautical services, which generally are related to the use of airport facilities by airlines and passengers and principally consist of a fee for each departing passenger, aircraft landing fees based on an aircraft’s weight and arrival time, an aircraft parking fee, a fee for the transfer of passengers from an aircraft to the terminal building and a security charge for each departing passenger.

Since January 1, 2000, all of our revenues from aeronautical services have been subject to a price regulation system established by the Ministry of Communications and Transportation. Under this price regulation system, the Ministry of Communications and Transportation establishes a maximum rate for each airport for every year in a five-year period. The maximum rate is the maximum amount of revenues per workload unit that may be earned at an airport each year from regulated revenues sources. Under this regulation, a workload unit is equivalent to one terminal passenger or 100 kilograms of cargo. We are able to set the specific prices for each aeronautical service every six months (or more frequently if accumulated inflation since the last adjustment exceeds 5%), as long as the combined revenues from regulated services at an airport do not exceed the maximum rate per workload unit at that airport. Since our aggregate revenues resulting from regulated services are not otherwise restricted, increases in passenger and cargo traffic permit greater revenues overall within each five-year interval for which maximum rates are established.

68

On July 15, 2003, we entered into an agreement with the National Air Transportation Chamber of Commerce (Cámara Nacional de Aerotransportes) and the Ministry of Communications and Transportation pursuant to which we resolved existing disputes with our principal airline customers and established specific prices for aeronautical services applicable to those airlines for 2003 and 2004 and a methodology for retroactively applying those prices from 2000, since these airlines had refused to pay certain of our charges since that year. In March 2005, we renewed an agreement with these customers that expired at year-end 2006. In December 2006 a new agreement was signed that covers an increasing percentage of total passenger charges over the years 2007, 2008 and 2009 and has set prices for each aeronautical service over this three-year period, with increases only possible as a result of the average of increases in the Consumer Price Index (Índice Nacional de Precios al Consumidor) and the Producers Price Index Excluding Petroleum (Índice Nacional de Precios al Productor, excluyendo petróleo) published by the Mexican Central Bank.

In 2007, approximately 80.9% of our total revenues were earned from aeronautical services subject to price regulation under our maximum rates.

Our revenues from non-aeronautical services, including revenues that we earn from most commercial activities in our terminals, are not regulated under our maximum-rate price regulation system and are therefore not subject to a ceiling. For a description of how we classify our revenues into aeronautical and non-aeronautical services, see “Item 5, Operating and Financial Review and Prospects—Classification of Revenues.”

Maximum Rates for 2005 through 2009

Each airport’s maximum rate is determined by the Ministry of Communications and Transportation based on a general framework established in our concessions. This framework reflects, among other factors, projections of an airport’s revenues, operating costs and capital expenditures, as well as the estimated cost of capital related to regulated services and projected annual efficiency adjustments determined by the Ministry of Communications and Transportation. The schedule of maximum rates for each airport is to be established every five years. In December 2004, the Ministry of Communications and Transportation set new airport maximum rates for the period from January 1, 2005 through December 31, 2009.

The following tables set forth the maximum rates for each of our airports under the master development programs that went into effect as of January 1, 2005. These maximum rates are subject to adjustment only as described above or under the limited circumstances described below under “Special Adjustments to Maximum Rates.”

Methodology for Determining Future Maximum Rates

The Rate Regulation provides that each airport’s annual maximum rates are to be determined in five-year intervals based on the following variables:

• Projections for the following fifteen years of workload units (each of which is equivalent to one terminal passenger or 100 kilograms of cargo), operating costs and expenses related to services subject to price regulation and pre-tax earnings from services subject to price regulation. The concessions provide that projections for workload units and expenses related to regulated services are to be derived from the terms of the relevant concession holder’s master development program for the following fifteen years.

• Projections for the following fifteen years of capital expenditures related to regulated services, based on air traffic forecasts and quality standards for services to be derived from the master development programs.

• Reference values, which initially were established in the concessions and are designed to reflect the net present value of the regulated revenues minus the corresponding regulated operating costs and expenses (excluding amortization and depreciation), and capital expenditures related to the provision of regulated services plus a terminal value.

• A discount rate to be determined by the Ministry of Communications and Transportation. The concessions provide that the discount rate shall reflect the cost of capital to Mexican and international companies in the airport industry (on a pre-tax basis), as well as Mexican economic conditions. The concessions provide that the discount rate shall be at least equal to the average yield of long-term Mexican government debt securities quoted in the international markets during the prior 24 months plus a risk premium to be determined by the Ministry of Communications and Transportation based on the inherent risk of the airport business in Mexico.

70

• An efficiency factor to be determined by the Ministry of Communications and Transportation. For the five-year period ending December 31, 2009, the maximum rates applicable to our airports reflect a projected annual efficiency improvement of 0.75%.

Our concessions specify a discounted cash flow formula to be used by the Ministry of Communications and Transportation to determine the maximum rates that, given the projected pre-tax earnings, the efficiency adjustment, capital expenditures and discount rate, would result in a net present value equal to the reference values established in connection with the last determination of maximum rates. We prepare a proposal to submit to the Ministry of Communications and Transportation establishing the values we believe should be used with respect to each variable included in the determination of maximum rates, including the efficiency factor, projected capital expenditures and the discount rate. The maximum rates ultimately established by the Ministry of Communications and Transportation historically have resulted from a negotiation between the Ministry of Communications and Transportation and us regarding these variables.

The concessions provide that each airport’s reference values and discount rate and the other variables used in calculating the maximum rates do not in any manner represent an undertaking by the Ministry of Communications and Transportation or the Mexican government as to the profitability of any concession holder. Therefore, whether or not the maximum rates (or the amounts up to the maximum rates that we are able to collect) multiplied by workload units at any airport generate a profit or exceed our profit estimates, or reflect the actual profitability, discount rates, capital expenditures or productivity gains at that airport over the five-year period, we are not entitled to any adjustment to compensate for any shortfall.

To the extent that such aggregate revenues per workload unit exceed the relevant maximum rate, the Ministry of Communications and Transportation may proportionately reduce the maximum rate in the immediately subsequent year and assess penalties equivalent to 1,000 to 50,000 times the general minimum wage in Mexico City. On December 31, 2007, the daily minimum wage in Mexico City was Ps. 50.6. As a result, the maximum penalty at such date could have been Ps. 2.5 million (U.S.$ 0.2 million) per airport.

Our concessions provide that, during 2000 and 2001, our calculation of workload units (one passenger or 100 kilograms of cargo) would include transit passengers. Beginning January 1, 2002, the Ministry of Communications and Transportation established that the calculation of workload units would not include transit passengers for subsequent years. The current workload unit calculation is therefore equal to one terminal passenger or 100 kilograms of cargo.

Special Adjustments to Maximum Rates

Once determined, each airport’s maximum rates are subject to special adjustment only under the following circumstances:

• Change in law or natural disasters.A concession holder may request an adjustment in its maximum rates if a change in law with respect to quality standards or safety and environmental protection results in operating costs or capital expenditures that were not contemplated when its maximum rates were determined. In addition, a concession holder may also request an adjustment in its maximum rates if a natural disaster affects demand or requires unanticipated capital expenditures. There can be no assurance that any request on these grounds would be approved.

71

• Macroeconomic conditions.A concession holder may request an adjustment in its maximum rates if, as a result of a decrease of at least 5% in Mexican gross domestic product in a 12-month period, the workload units processed in the concession holder’s airport are less than those projected when its master development program was approved. To grant an adjustment under these circumstances, the Ministry of Communications and Transportation must have already allowed the concession holder to decrease its projected capital improvements under its master development program as a result of the decline in passenger traffic volume. There can be no assurance that any request on these grounds would be approved.

• Increase in concession tax under Mexican Federal Duties Law.An increase in duty payable by a concession holder under the Mexican Federal Duties Law entitles the concession holder to request an adjustment in its maximum rates. There can be no assurance that any request on these grounds would be approved.

• Failure to make required investments or improvements.The Ministry of Communications and Transportation annually is entitled to review each concession holder’s compliance with its master development program (including the provision of services and the making of capital investments). If a concession holder fails to satisfy any of the investment commitments contained in its master development program, the Ministry of Communications and Transportation is entitled to decrease the concession holder’s maximum rates and assess penalties.

• Excess revenues.In the event that revenues subject to price regulation per workload unit in any year exceed the applicable maximum rate, the maximum rate for the following year will be decreased to compensate airport users for overpayment in the previous year. Under these circumstances, the Ministry of Communications and Transportation is also entitled to assess penalties against the concession holder.

Ownership Commitments and Restrictions

The concessions require us to retain a 51% direct ownership interest in each of our 12 concession holders throughout the term of these concessions. Any acquisition by us or one of our concession holders of any additional airport concessions or of a beneficial interest of 30% or more of another concession holder requires the consent of the Mexican Antitrust Commission. In addition, the concessions prohibit us and our concession holders, collectively or individually, from acquiring more than one concession for the operation of an airport along each of Mexico’s southern and northern borders.

72

Air carriers are prohibited under the Mexican Airport Law from controlling or beneficially owning 5% or more of the shares of a holder of an airport concession. We, and each of our subsidiaries, are similarly restricted from owning 5% or more of the shares of any air carrier.

Foreign governments acting in a sovereign capacity are prohibited from owning any direct or indirect equity interest in a holder of an airport concession.

Reporting, Information and Consent Requirements

Concession holders and third parties providing services at airports are required to provide the Ministry of Communications and Transportation access to all airport facilities and information relating to an airport’s construction, operation, maintenance and development. Each concession holder is obligated to maintain statistical records of operations and air traffic movements in its airport and to provide the Ministry of Communications and Transportation with any information that it may request. Each concession holder is also required to publish its annual audited consolidated financial statements in a principal Mexican newspaper within the first four months of each year.

The Mexican Airport Law provides that any person or group directly or indirectly acquiring control of a concession holder is required to obtain the consent of the Ministry of Communications and Transportation for such control acquisition. For purposes of this requirement, control is deemed to be acquired in the following circumstances:

• if a person acquires 35% or more of the shares of a concession holder;

• if a person has the ability to control the outcome of meetings of the stockholders of a concession holder;

• if a person has the ability to appoint a majority of the members of the board of directors of a concession holder; and

• if a person by any other means acquires control of an airport.

Pursuant to the regulations under the Mexican Airport Law, any company acquiring control of a concession holder is deemed to be jointly and severally liable with the concession holder for the performance of the terms and conditions of the concession.

The Ministry of Communications and Transportation is required to be notified upon any change in a concession holder’s chief executive officer, board of directors or management. A concession holder is also required to notify the Ministry of Communications and Transportation at least 90 days prior to the adoption of any amendment to its bylaws concerning the dissolution, corporate purpose, merger, transformation or spin-off of the concession holder.

73

Penalties and Termination and Revocation of Concessions and Concession Assets

Termination of Concessions

Under the Mexican Airport Law and the terms of the concessions, a concession may be terminated upon any of the following events:

• the expiration of its term;

• its surrender by the concession holder;

• the revocation of the concession by the Ministry of Communications and Transportation;

• the reversion (rescate) of the Mexican government-owned assets that are the subject of the concession (principally real estate, improvements and other infrastructure);

• the inability to achieve the purpose of the concession, except in the event offorce majeure;

• the dissolution, liquidation or bankruptcy of the concession holder; or

• the failure by the concession holder to satisfy the shareholding obligations set forth in the concession.

Following a concession’s termination, the concession holder remains liable for the performance of its obligations during the term of the concession.

Revocation of Concessions

A concession may be revoked by the Ministry of Communications and Transportation under certain conditions, including:

• the failure by a concession holder to operate, maintain and develop an airport pursuant to the terms established in the concession;

• the failure by a concession holder to maintain insurance as required under the Mexican Airport Law;

• the assignment, encumbrance, transfer or sale of a concession, any of the rights thereunder or the assets underlying the concession in violation of the Mexican Airport Law;

• any alteration of the nature or condition of an airport’s facilities without the authorization of the Ministry of Communications and Transportation;

• use, with a concession holder’s consent or without the approval of air traffic control authorities, of an airport by any aircraft that does not comply with the requirements of the Mexican Civil Aviation Law, that has not been authorized by the Mexican Air Traffic Control Authority, or that is involved in the commission of a felony;

74

• knowingly appointing a chief executive officer or board member of a concession holder that is not qualified to perform his functions under the law as a result of having violated criminal laws;

• the failure by the concession holder to pay the Mexican government the airport concession tax;

• failure to own at least 51% of the capital stock of subsidiary concession holders;

• violation of the safety regulations established in the Mexican Airport Law and other applicable laws;

• total or partial interruption of the operation of an airport or its airport or complementary services without justified cause;

• the failure to maintain an airport’s facilities;

• the provision of unauthorized services;

• the failure to indemnify a third party for damages caused by the provision of services by the concession holder or a third-party service provider;

• charging prices higher than those registered with the Ministry of Communications and Transportation for regulated services or exceeding the applicable maximum rate;

• any act or omission that impedes the ability of other service providers or authorities to carry out their functions within an airport; or

• any other failure to comply with the Mexican Airport Law, its regulations and the terms of a concession.

The Ministry of Communications and Transportation is entitled to revoke a concession without prior notice as a result of the first six events described above. In the case of other violations, a concession may be revoked as a result of a violation only if sanctions have been imposed at least three times with respect to the same violation.

Pursuant to the terms of our concessions, in the event the Ministry of Communications and Transportation revokes one of our concessions, it is entitled to revoke all of our concessions.

According to the Mexican National Assets Law, the surface area of our airports and improvements on such space are government-owned assets. A concession concerning government-owned assets may be “rescued”, or revert to the Mexican government prior to the concession’s expiration, when considered necessary for the public interest. In exchange, the Mexican government is required to pay compensation as determined by expert appraisers.

75

Following a declaration of reversion (rescate), the assets that were subject to the concession are automatically returned to the Mexican government.

In the event of war, public disturbances or threats to national security, the Mexican government may assume the operation (requisa) of any airport, airport and complementary services as well as any other airport assets. Such government action may exist only during the duration of the emergency. Except in the case of war, the Mexican federal government is required to compensate all affected parties for any damages or losses suffered as a result of such government action. If the Mexican government and a concession holder cannot agree as to the appropriate amount of damages or losses, the amount of damages must be determined by experts jointly appointed by both parties and the amount of losses must be determined based on the average net income of the concession holder during the previous year.

The Mexican Airport Law provides that a sanction of up to 200,000 times the minimum daily wage in Mexico City may be assessed for a failure to comply with the law or terms of a concession. Such sanction may be duplicated in the event of reiterative failures to comply. On December 31, 2007, the daily minimum wage in Mexico City was Ps. 50.6. As a result, the maximum penalty at such date was Ps. 10.1 million (U.S.$ 0.9 million) for an individual failure to comply.

Consequences of Termination or Revocation of a Concession

Upon termination, whether as a result of expiration or revocation, the real estate and fixtures that were the subject of the concession automatically revert to the Mexican government. In addition, upon termination, the Mexican federal government has a preemptive right to acquire all other assets used by the concession holder to provide services under the concession at prices determined by expert appraisers appointed by the Ministry of Communications and Transportation. Alternatively, the Mexican government may elect to lease these assets for up to five years at fair market rates as determined by expert appraisers appointed by the Mexican government and the concession holder. In the event of a discrepancy between appraisals, a third expert appraiser must be jointly appointed by the Mexican government and the concession holder. If the concession holder does not appoint an expert appraiser, or if such appraiser fails to determine a price, the determination of the appraiser appointed by the Mexican government will be conclusive. If the Mexican government chooses to lease the assets, it may thereafter purchase the assets at their fair market value, as determined by an expert appraiser appointed by the Mexican government.

The Mexican Communications Law, however, provides that upon expiration, termination or revocation of a concession, all assets necessary to operate the airports will revert to the Mexican government, at no cost, and free of any liens or other encumbrances. There is substantial doubt as to whether the provisions of our concessions would prevail over those of the Mexican Communications Law. Accordingly, there can be no assurance that upon expiration or termination of our concessions the assets used by our subsidiary concession holders to provide services at our airports will not revert to the Mexican government, free of charge, together with government-owned assets and improvements permanently attached thereto.

Grants of New Concessions

The Mexican government may grant new concessions to manage, operate, develop and construct airports. Such concessions may be granted through a public bidding process in which bidders must demonstrate their technical, legal, managerial and financial capabilities. The Federal Competition Commission has the power, under certain circumstances, to prohibit a party from bidding and to cancel an award after the process has concluded. In addition, the government may grant concessions without a public bidding process to the following entities:

• any person who holds a permit to operate a civil aerodrome and intends to transform the aerodrome into an airport so long as (i) the proposed change is consistent with the national airport development programs and policies, (ii) the civil aerodrome has been in continuous operation for the previous five years and (iii) the permit holder complies with all requirements of the concession,

• a current concession holder when necessary to meet increased demand so long as (i) a new airport is necessary to increase existing capacity, (ii) the operation of both airports by a single concession holder is more efficient than other options, and (iii) the concession holder complies with all requirements of the concession,

• a current concession holder when it is in the public interest for its airport to be relocated,

• entities in the federal public administration, and

• commercial entities in which local or municipal governments have a majority equity interest if the entities’ corporate purpose is to manage, operate, develop and/or construct airports.

Environmental Regulation

Our operations are subject to Mexican federal, state and municipal laws and regulations relating to the protection of the environment. The major federal environmental laws applicable to our operations are: (i) the General Law of Ecological Balance and Environmental Protection (Ley General de Equilibrio Ecológico y Protección Ambiental) (the “General Environmental Law”) and its regulations, which are administered by the Ministry of the Environment and Natural Resources (Secretaría de Medio Ambiente y Recursos Naturales) and enforced by the Ministry’s enforcement branch, the Federal Office for the Protection of the Environment (Procuraduría Federal de Protección al Ambiente); (ii) the General Law for the Prevention and Integral Management of Waste (Ley General para la Prevención y Gestión Integral de los Residuos) (the “Law on Waste”), which is also administered by the Ministry of the Environment and Natural Resources and enforced by the Federal Office for the Protection of the Environment; and (iii) the National Waters Law (Ley de Aguas Nacionales) and its regulations, which are administered and enforced by the National Waters Commission, (Comisión Nacional del Agua), also a branch of the Ministry of the Environment and Natural Resources.

Under the General Environmental Law, regulations have been enacted concerning air pollution, environmental impact, noise control, hazardous waste, environmental audits and

77

natural protected areas. The General Environmental Law also regulates, among other things, vibrations, thermal energy, soil contamination and visual pollution, although the Mexican government has not yet issued enforceable regulation on the majority of these matters. The General Environmental Law also provides that companies that contaminate soils are responsible for their clean-up. Further, according to the Law on Waste, which was enacted in January 2004, owners and/or possessors of real property with soil contamination are jointly and severally liable for the remediation of such contaminated sites, irrespective of any recourse or other actions such owners and/or possessors may have against the contaminating party, and aside from the criminal or administrative liability to which the contaminating party may be subject. Restrictions on the transfer of contaminated sites also exist. The Law on Waste also regulates the generation, handling and final disposal of hazardous waste.

Pursuant to the National Waters Law, companies that discharge waste waters into national water bodies must comply with, among other requirements, maximum permissible contaminant levels in order to preserve water quality. Periodic reports on water quality must be provided to competent authorities. Liability may result from the contamination of underground waters or recipient water bodies. The use of underground waters is subject to restrictions pursuant to our concessions and the National Waters Commission.

In addition to the foregoing, Mexican Official Norms (Normas Oficiales Mexicanas), which are technical standards issued by competent regulatory authorities pursuant to the General Normalization Law (Ley General de Metrología y Normalización) and to other laws that include the environmental laws described above, establish standards relating to air emissions, waste water discharges, the generation, handling and disposal of hazardous waste and noise control, among other matters. As of December 31, 2007, Mexican Official Norms on soil contamination and waste management were in the process of being developed. Although not enforceable, the internal administrative criteria on soil contamination of the Federal Office for the Protection of the Environment are widely used as guidance in cases where soil remediation, restoration or clean-up is required.

The Federal Office for the Protection of the Environment can bring administrative, civil and criminal proceedings against companies that violate environmental laws and it also has the power to close non-complying facilities and impose a variety of sanctions. Companies in Mexico are required to obtain proper authorizations, licenses, concessions or permits from competent environmental authorities for the performance of activities that may have an impact on the environment or that may constitute a source of contamination. Companies in Mexico are also required to comply with a variety of reporting obligations that include, among others, providing the Federal Office for the Protection of the Environment and the National Waters Commission, as applicable, with periodic reports regarding compliance with various environmental laws.

Prior to the opening of Mexico’s airports to private investment, the Federal Office for the Protection of the Environment required that environmental audits be performed at each of our airports. Based on the results of these audits, the Federal Office for the Protection of the Environment issued recommendations for improvements and corrective actions to be taken at each of our airports. In connection with the transfer of the management of our airports from our predecessor, we entered into environmental compliance agreements with the Federal Office for

78

the Protection of the Environment on January 1, 1999 and July 12, 2000 pursuant to which we agreed to comply with a specific action plan and adopt specific actions within a determined time frame.

The Federal Office for the Protection of the Environment has confirmed that we have complied with all of the relevant environmental requirements derived from the aforementioned environmental audits at, and has issued compliance certificates for, all of our airports other than Guadalajara. These certificates, which are known as Environmental Compliance Certificates (Certificados de Cumplimiento Ambiental) certify compliance with applicable Mexican environmental laws, regulations and applicable Mexican Official Norms and must be renewed periodically. During the remainder of 2007, we must obtain renewals for our airports in Aguascalientes, Morelia, Manzanillo, La Paz and Mexicali. We are in the process of completing the certification process in respect of our Guadalajara airport with the Federal Office for the Protection of the Environment.

Liability for Environmental Noncompliance

The legal framework of environmental liability applicable to our operations is generally outlined above. Under the terms of our concessions, the Mexican government has agreed to indemnify us for any environmental liabilities arising prior to November 1, 1998 and for any failure by the Mexican Airport and Auxiliary Services Agency prior to November 1, 1998 to comply with applicable environmental laws and with its agreements with Mexican environmental authorities. Although there can be no assurance, we believe that we are entitled to indemnification for any liabilities related to the actions our predecessor was required to perform or refrain from performing under applicable environmental laws and under its agreements with environmental authorities. For further information regarding these liabilities, see Note 17.c to our audited consolidated financial statements.

The level of environmental regulation in Mexico has significantly increased in recent years, and the enforcement of environmental laws is becoming substantially more stringent. We expect this trend to continue and expect additional norms to be imposed by the North American Agreement on Environmental Cooperation entered into by Canada, the United States and Mexico in the context of the North American Free Trade Agreement, as well as by other international treaties on environmental matters. We do not expect that compliance with Mexican federal, state or municipal environmental laws currently in effect will have a material adverse effect on our financial condition or results of operations. However, there can be no assurance that environmental regulations or the enforcement thereof will not change in a manner that could have a material adverse effect on our business, results of operations, prospects or financial condition.

Item 5. Operating and Financial Review and Prospects

The following discussion is derived from our audited consolidated financial statements, which are included elsewhere in this annual report. This discussion does not include all of the information included in these financial statements. You should read these financial statements to gain a better understanding of our business and our historical results of operations.

Our audited consolidated financial statements have been prepared in accordance with MFRS, which differ in certain respects from U.S. GAAP. See Note 24 to our audited consolidated financial statements for a description of the principal differences between MFRS and U.S. GAAP as they relate to us.

Overview

We operate 12 airports in the Pacific and Central regions of Mexico pursuant to concessions granted by the Mexican government. The substantial majority of our revenues is derived from providing aeronautical services, which generally are related to the use of our airport facilities by airlines and passengers. For example, approximately 80.9% of our total revenues in 2007 were earned from aeronautical services. Changes in our revenues from aeronautical services are principally driven by the passenger and cargo volumes at our airports. Our revenues from aeronautical services are also affected by the maximum rates we are allowed to charge under the price regulation system established by the Ministry of Communications and Transportation. The maximum rate system of price regulation that applies to our aeronautical revenues is linked to the traffic volume (measured in workload units) at each airport; thus, increases in passenger and cargo volume generally permit greater revenues from aeronautical services.

81

We also derive revenues from non-aeronautical activities, which principally relate to the commercial, non-aeronautical activities carried out at our airports such as the leasing of space to restaurants and retailers. Our revenues from non-aeronautical activities are not subject to the system of price regulation established by the Ministry of Communications and Transportation. Thus, our non-aeronautical revenues are principally affected by the passenger volume at our airports and the mix of commercial activities carried out at our airports. While we believe aeronautical revenues will continue to represent a substantial majority of our future total revenues, we anticipate that the future growth of our revenues from commercial activities will exceed the growth rate of our aeronautical revenues.

Recent Developments

Report of the Federal Competition Commission on Mexico’s Airports

On October 1, 2007, the Chairman of Federal Competition Commission (Comisión Federal de Competencia, or the “Competition Commission”) released an independent report on the competitiveness of Mexico’s airports relative to each other and to international airports. The report alleged that, between 2001 and 2007, operating income (expressed as a percentage of total revenues) of Mexican airports was relatively high when compared with a sample of fifty international airports. In addition, the report suggested that aeronautical services charges at Mexican airports were more expensive than at most of the fifty comparison airports. The report also claimed that operating income at Mexican airports had increased principally as a result of increased passenger traffic, rather than increases in operating efficiency. To that end, the Competition Commission Chairman’s report made the following recommendations as ways to increase efficiency at Mexican airports:

• Make economic efficiency a basis of tariff regulation for new concessions;

• Include commercial services income as one of the factors in determining tariffs for new concessions;

• Strengthen the independence of the regulatory agency, and increase the transparency of airport regulation;

• Promote greater efficiency in scheduling at saturated airports;

• Promote greater competition between airports;

• Eliminate Aeropuertos y Servicios Auxiliares’ (“ASA”) role as exclusive fuel service provider;

• Eliminate barriers to entry for taxi providers at airports; and

• Be mindful of vertical integration among airports and airlines.

82

The Ministry of Communications and Transportation issued a response to the Competition Commission Chairman’s report that noted, among other matters, that according to its own calculations, Mexico’s airport charges were lower than 36 of the 50 international airports against which they were compared. We also issued a joint press release along with the other two Mexican airport groups, Grupo Aeroportuario del Sureste and Grupo Aeroportuario del Centro Norte, questioning the calculations and the comparisons drawn in the Competition Commission Chairman’s report, and stating that we are committed to participate in a comprehensive review of the report in order to demonstrate our commitment to the efficient development of the airport sector. In addition, before the Competition Commission Chairman’s report was released, an initiative was introduced in Mexico’s Congress to make certain reforms to the Mexican Airports Law. Although we do not expect that the Competition Commission Chairman’s report or the congressional initiative will result in any regulatory changes in the short term, there can be no assurance that changes to the airport regulatory framework will not occur in the future. See “Risk Factors— Risks Related to the Regulation of Our Business.”

Passenger and Cargo Volumes

The majority of the passenger traffic volume in our airports is made up of domestic passengers. In addition, of the international passengers traveling through our airports, a majority has historically traveled on flights originating in or departing to the United States. Accordingly, our results of operations are influenced strongly by changes to Mexican economic conditions and to a lesser extent influenced by U.S. economic and other conditions, particularly trends and events affecting leisure travel and consumer spending. Many factors affecting our passenger traffic volume and the mix of passenger traffic in our airports are beyond our control.

(3) In thousands. One cargo unit is equivalent to 100 kilograms of cargo. Under the regulation applicable to our aeronautical revenues, one workload unit is equivalent to one terminal passenger or one cargo unit.

(4) In each case, as compared to the previous period.

(5) In millions of constant pesos.

(6) In thousands.

In 2007, we had 23.6 million terminal passengers (15.8 million domestic and 7.8 million international), of which 121.0 thousand were on general aviation flights, and an additional 958 thousand transit passengers. Approximately 48.6% of our transit passengers are handled at Guadalajara International Airport.

Classification of Revenues

We classify our revenues into two categories: revenues from aeronautical services and revenues from non-aeronautical services. Historically, a substantial majority of our revenues have been derived from aeronautical services. For example, in 2005, 2006 and 2007, 81.5%, 81.4% and 80.9%, respectively, of our revenues were derived from aeronautical services and the remainder of our revenues was derived from non-aeronautical services.

Our revenues from aeronautical services are subject to price regulation under the applicable maximum rate at each of our airports, and principally consist of passenger charges, aircraft landing and parking charges, airport security charges, passenger walkway charges, leasing of space in our airports to airlines (other than first class/VIP lounges and other similar non-essential activities) and complementary services (i.e., fees from handling and catering providers, permanent ground transportation operators and access fees from fuel providers at our airports).

84

Our revenues from non-aeronautical services are not subject to price regulation under our maximum rates and generally include revenues earned from car parking, leasing of space in our airports to airlines and complementary service providers (for first class/VIP lounges and similar non-essential activities), rental and royalty payments from third parties operating stores and providing commercial services at our airports, such as car rental agencies, food and beverage providers and retail and duty-free store operators, as well as advertising and fees collected from other miscellaneous sources, such as vending machines and time-share companies.

For a detailed description of the components of our aeronautical and non-aeronautical revenues categories, see “Item 4, Information on the Company—Business Overview—Our Sources of Revenues.”

Aeronautical Revenues

The system of price regulation applicable to our aeronautical revenues establishes a maximum rate in pesos for each airport for each year in a five-year period, which is the maximum annual amount of revenues per workload unit (which is equal to one terminal passenger or 100 kilograms of cargo) that we may earn at that airport from aeronautical services. See “Item 4, Regulatory Framework—Aeronautical Services Regulation” for a description of our maximum rates and the rate-setting procedures for future periods. The maximum rates for our airports have been determined for each year through December 31, 2009.

The following table sets forth our revenues from aeronautical services for the years indicated.

(1) Revenues from complementary service providers consist of access and other fees charged to third parties providing handling, catering and other services at our airports.

(2) In millions. Under the regulation applicable to our aeronautical revenues, a workload unit is equivalent to one terminal passenger or 100 kilograms of cargo.

(3) In each case, as compared to the previous year.

85

Under the regulatory system applicable to our aeronautical revenues, we can set the specific price for each category of aeronautical services every six months (or more frequently if accumulated inflation since the last adjustment exceeds 5%), as long as the total aeronautical revenues per workload unit each year at each of our airports do not exceed the maximum rate at that airport for that year. The specific prices we charge for regulated services are determined based on various factors, including projections of passenger traffic volumes, capital expenditures estimated under our master development programs, the Mexican Producer Price Index (excluding petroleum) and the value of the peso relative to the U.S. dollar. We currently set the specific price for each category of aeronautical services after negotiating with our principal airline customers. Under the relevant agreements, our specific prices are structured such that the substantial majority of our aeronautical revenues are derived from passenger charges, and we expect this to continue to be the case in any future agreements. In 2005, 2006 and 2007, passenger charges represented 80.2%, 80.0% and 83.2%, respectively, of our aeronautical services revenues and 65.4%, 65.1% and 67.3%, respectively, of our total revenues.

Historically, we have set the prices we charge for regulated services at each airport in order to come as close as possible to the maximum rates we are allowed to charge for that airport in any given year, and we expect to continue to pursue this pricing strategy in the future. In December 2004, the Ministry of Communications and Transportation established new maximum rates applicable to our airports for the period from January 1, 2005 through December 31, 2009 that are higher than the maximum rates that were applicable to our airports for the prior five-year period. There can be no assurance that we will be able to collect virtually all of the revenues we are entitled to earn from services subject to price regulation in the future. For a discussion of risks relating to our ability to set specific prices, see “Item 3, Risk Factors—Risks Related to Our Operations—The principal domestic airlines operating at our airports have in the past refused to pay certain increases in our specific prices for aeronautical services and could refuse to pay additional increases in the future.”

In prior years, in order to ensure our compliance with the maximum rate at a particular airport when the possibility of exceeding that maximum rate arose, we have taken actions in the latter part of the year, such as reducing our specific prices for aeronautical services and offering discounts or rebates, to ensure our compliance with the applicable maximum rate. In the future, we intend to continue to adjust our rates in the latter part of each year to ensure compliance with our maximum rates.

Revenues from passenger charges have fluctuated in recent periods at our Tijuana International Airport and our Mexicali International Airport, as more passengers have been traveling to the United States have alternated between these airports and other alternative airports, such as our Guadalajara, Guanajuato and Aguascalientes International Airports. In 2005, passengers paying passenger charges at our Tijuana International Airport and our Mexicali International Airport increased by 2.2% and declined by 1.3%, respectively, as compared to 2004. In 2006, passengers paying passenger charges at our Tijuana International Airport and our Mexicali International Airport increased 9.2% and declined 3.8%, respectively, as compared to 2005. In 2007, passengers paying passenger charges at our Tijuana International Airport and our Mexicali International Airport increased by 29.0% and 30.1%, respectively, as compared to 2006. Passenger traffic volumes at both our Tijuana International Airport and our Mexicali International Airport principally reflect border-crossing volumes near each of these

86

airports. Many of the passengers using our Tijuana International Airport and our Mexicali International Airport are traveling to and from the United States, and delays at the San Diego-Tijuana or the Calexico-Mexicali border crossing have caused travelers to use other routes to enter and leave the United States. We believe many travelers have elected to take direct flights to or from the United States from our Aguascalientes, Guanajuato and Guadalajara international airports.

The following table sets forth the number of passengers paying passenger charges for the years indicated. We earn passenger charges from each departing passenger at our airports, other than transit passengers, diplomats and infants.

Non-aeronautical Revenues

Non-aeronautical services historically have generated a significantly smaller portion of our total revenues as compared to aeronautical services. However, the contribution to our total revenues from non-aeronautical services has increased recently, from 18.5% in 2005 to 19.1% in 2007, reflecting our business strategy of developing our commercial activities. During this period, our non-aeronautical revenues per terminal passenger increased, from Ps. 27.0 in 2005 to Ps. 28.2 in 2007. Our revenues from non-aeronautical services are principally derived from commercial activities. None of our revenues from non-aeronautical services are subject to price regulation under our maximum-rate price regulation system.

The following table sets forth our revenues from non-aeronautical activities for the years indicated.

(2) Recovery of costs consists of utility and maintenance charges that are transferred to airlines and other tenants in our airports.

(3) In millions.

(4) In each case, as compared to the previous year.

The majority of our non-aeronautical revenues is derived from commercial activities such as car parking, leasing of space in our airports to airlines and complementary service providers (for first class/VIP lounges and similar non-essential activities) and rental and royalty payments from third parties operating stores and providing commercial services at our airports, such as time-share developers, retail stores, food and beverage providers, car rental agencies and duty-free store operators, as well as advertising and fees collected from other miscellaneous sources, such as vending machines.

Leading privatized airports typically generate a greater portion of their revenues from commercial activities than we currently do. We estimate that, prior to 2002, revenues from commercial activities in our airports generally accounted for less than 12% of the total revenues generated by our airports. In contrast, we believe that revenues from commercial activities account for up to 40% or more of the consolidated revenues of many leading privatized airports. While we believe that aeronautical revenues will continue to represent a substantial majority of our future revenues, we anticipate that the future growth rate of our revenues from commercial activities will exceed the growth rate of our aeronautical revenues. In recent years, non-aeronautical revenues per terminal passenger have increased (from Ps. 27.0 in 2005 to Ps. 28.2 in 2007), while our cost of services per workload unit has decreased 2.3% (Ps. 34.1 in 2005, as compared to Ps. 33.3 in 2007), resulting in non-aeronautical services contributing increasingly to our results of operations.

(4) Cost of services divided by total revenues, expressed as a percentage.

Cost of Services

Our cost of services consists primarily of employee costs, maintenance, safety, security and insurance costs, utilities (a portion of which we recover from our tenants) and various other operating costs. In recent years, our cost of services per workload unit has decreased modestly from Ps. 34.1 in 2005 to Ps. 33.3 in 2007. This stability and control over our cost of services per workload unit, together with increases in revenues in recent years, has increased our operating margins (defined as income from operations divided by total revenues) by 300 basis points from 42.5% in 2005 to 45.5% in 2007.

89

Technical Assistance Fee and Concession Tax

Under the technical assistance agreement, AMP provides management and consulting services as well as technical assistance and technological and industry knowledge and experience to us in exchange for a fee. This agreement is more fully described in Item 7 hereof. The technical assistance fee for each of 2000 and 2001 was fixed at U.S.$ 7.0 million (adjusted annually for U.S. inflation since August 25, 2000). Subsequent to January 1, 2002, the fee has been equal to the greater of U.S.$ 4.0 million (adjusted annually for U.S. inflation since August 25, 2000) and 5% of our annual consolidated income from operations (calculated prior to deducting the technical assistance fee and depreciation and amortization and in each case determined in accordance with MFRS).

Beginning November 1, 1998, we became subject to the Mexican Federal Duties Law, which requires each of our airports to pay a concession tax to the Mexican government, which is currently equal to 5% of the gross annual revenues of each concession holder obtained from the use of public domain assets pursuant to the terms of its concession. The concession tax may vary on an annual basis as determined solely by the Mexican federal congress, and there can be no assurance that this fee may not increase in the future. If the Mexican federal congress increases the concession tax, we are entitled to request an increase in our maximum rates from the Ministry of Communications and Transportation; however, there can be no assurance that the Ministry of Communications and Transportation would honor our request.

Depreciation and Amortization

Our depreciation and amortization expenses reflect primarily the amortization of our investment in our 12 concessions, which we began amortizing for accounting purposes in August 1999, the date on which the value of our concessions was determined based on the value assigned by AMP to our Series BB shares as part of its winning bid to acquire its 15% interest in us. In addition, we depreciate the value of certain fixed assets we acquire or build at our airports pursuant to the investment requirements under our master development programs. Moreover, in 2006 and 2007, we recognized anticipated depreciation from some additions to and construction upon facilities carried out during 2006 and 2007, respectively. The amount of these effects were Ps. 35.8 and 10.9 million, respectively. Beginning in October 2004, we changed the amortization rates applicable to our concessions. The effect of this change was an increase of Ps. 34.5 million of amortization expense for the year ended December 31, 2005, as compared to 2004 (due to the fact that new rates were in effect for all of 2005 and only part of 2004), and an increase of Ps. 11.5 million for the year ended December 31, 2004, as compared to 2003 (due to the fact that the rates were in effect for part of 2004, but not in effect during 2003).

Taxation

We and each of our subsidiaries pay taxes on an individual (rather than consolidated) basis. Mexican companies are generally required to pay the greater of their income tax liability (determined at a rate of 30% for 2005, 29% for 2006, 28% for thereafter) or their asset tax liability (determined at a rate of 1.8% – until December 2006 and 1.25% in 2007 – of the average tax value of virtually all of their assets including, in our case, our concessions), less the average tax value of certain liabilities (until December 2006; beginning in 2007, no liabilities

90

are deducted). Due to changes in the tax legislation, effective January 1, 2007, taxpayers who file tax reports and meet certain requirements may obtain a tax credit equivalent to 0.50% or 0.25% of taxable income. If, in any year, the asset tax liability exceeds the income tax liability, the asset tax payment for such excess may be reduced by the amount by which the income tax exceeded the asset tax in the three preceding years. In addition, any required payment of asset tax is creditable against the excess of income tax over asset tax of the following ten years. Mexican companies are exempt from the asset tax during the first three full fiscal years following the commencement of operations (which in our case occurred on November 1, 1998). Accordingly, we were exempt from the asset tax until December 31, 2001.

In 2005, 2006 and 2007, we and our subsidiaries paid an aggregate of Ps. 146.5 million, Ps. 125.9 million and Ps. 81.9 million, respectively, in asset taxes. As a result of changes in the Mexican tax law, the asset tax balance may be recovered through rebates over the following ten years of up to 10% of the total asset tax paid out and pending recovery, provided that this sum does not exceed the difference between the income tax paid during the period and the asset tax paid during the three previous years, whichever is lower, when the income tax exceeds asset tax in any of those years.

On October 1, 2007, a new flat rate business tax (Impuesto Empresarial a Tasa Única, or “IETU”) was approved by the Mexican government and became effective as of January 1, 2008.

In addition, the Tax Benefits Decree and the Third Omnibus Tax Bill were published on November 5 and December 31, 2007, respectively, clarifying or expanding the transitory application of the law regarding transactions carried out in 2007 that will have an impact in 2008. This law, which eliminated the asset tax and replaced it with the IETU as described below, applies to individuals and companies with permanent establishment in Mexico. Such individuals and companies are required to pay the greater of the IETU or the income tax. IETU is calculated by applying a tax rate of 16.5% in 2008, 17.0% in 2009 and 17.5% thereafter to an income determined based on cash flows. This income is determined by deducting authorized deductions (excluding wages, social security contributions and certain investment expenditures) from total income earned from taxable activities. IETU tax credits are deducted according to procedures established in the IETU tax law.

We regularly review our deferred tax assets for recoverability and, if necessary, establish a valuation allowance based on historical taxable income, projected future taxable income and the expected timing of the reversals of existing temporary differences. Mexican tax law allows Mexican companies utilizing tax amortization rates that are lower than the maximum allowable rates to modify their tax amortization rates every five years, without exceeding the maximum allowable rate. Beginning in 2000, we utilized rates lower than the 15% maximum allowable rate to amortize our airport concessions and rights to use airport facilities for tax purposes.

Beginning in January 2005, after the expiration of the five-year period and in order to optimize our effective tax rate and our long-term financial position, we elected to increase the tax amortization rates on our airport concessions and rights to use airport facilities at six of our 12 airports. As a result of the change in tax amortization rates and the increase in pre-tax income attributable to our recovery of commercial space at our Puerto Vallarta International Airport, in 2005 we reversed Ps. 40.6 million in valuation allowance charges and recorded a corresponding increase in our deferred tax asset.

91

Our effective tax rates in 2005, 2006 and 2007 were 41%, 29% and 17%, respectively. Our relatively high effective tax rate was historically the result of the valuation allowance we recorded each year against asset tax amounts that we did not expect to recover, prior to the final resolution in favor of the Aguascalientes, Hermosillo, La Paz, Los Mochis, Morelia and Manzanillo airports that was received in 2006. In 2007, our effective tax rate declined, reflecting an increase in our pre-tax income that was not matched by a proportionate increase in our tax provision, principally due to the favorable final resolution of, and partial refund in connection with, our tax claims in respect of the Aguascalientes, Hermosillo, La Paz, Los Mochis, Morelia and Manzanillo airports that produced: i) an adjustment reversing valuation allowances we took for those airports during 2002, 2003, 2004 and 2005 (such adjustment aggregating Ps. 144.8), and ii) a smaller valuation allowance for asset tax for the year 2006. The airports received the refund of Ps. 146,407 resulting in a pending balance of Ps. 62,156.

As a result of the enactment of IETU, the Company now has ten years, beginning in 2008 to recover existing asset tax credit carryforwards; as well, the IETU law established a mechanism to recover existing asset tax credit carryforwards that ultimately benefited the Company. Based on these changes which resulted in the Company’s ability to recover tax on assets that was previously determined to be unrecoverable, coupled with the Company’s financial projections from 2008 to 2017, in 2007, the Company recognized recoverable tax on assets paid in previous years for Ps. 354.9 million (Ps. 286.4 million nominal pesos), through the cancellation of the valuation allowance.

On January 1, 1999, we became subject to the statutory employee profit sharing regime established under the Mexican Federal Labor Law (Ley Federal del Trabajo). Under this regime, 10% of each unconsolidated company’s annual profits (as calculated for tax purposes) must be distributed among its employees, other than its chief executive officer.

Effects of Devaluation and Inflation

The following table sets forth, for the periods indicated:

• the percentage that the Mexican peso depreciated or appreciated against the U.S. dollar;

• the Mexican inflation rate;

• the U.S. inflation rate; and

• the percentage that the Mexican gross domestic product, or GDP, changed as compared to the previous period.

(1) Based on changes in the rates for calculating foreign exchange liabilities, as reported by Banco de México, the Mexican Central Bank, at the end of each period, which were as follows: Ps. 10.6344 per U.S. dollar as of December 31, 2005, Ps. 10.8116 per U.S. dollar as of December 31, 2006 and Ps. 10.9157 per U.S. dollar as of December 31, 2007.

(2) Based on changes in the Mexican consumer price index from the previous period, as reported by the Banco de México. The Mexican consumer price index at year end was: 116.3010 in 2005, 121.0150 in 2006 and 125.5640 in 2007.

(3) As reported by the U.S. Department of Labor, Bureau of Statistics.

(4) In real terms, as reported by the Mexican National Statistical, Geographic and Information Institute (INEGI) as of February, 19, 2008.

The general condition of the Mexican economy, changes in the value of the peso as compared to the dollar, inflation and high interest rates have in the past adversely affected, and may in the future adversely affect, our:

• Depreciation and amortization expense.Through 2007, we restated our non-monetary assets to give effect to inflation. The restatement of these assets in periods of high inflation increases the carrying value of these assets in pesos, which in turn increases the related depreciation expense and risk of impairments. Our airport concessions are being amortized on a straight-line basis over the life of the concession and rights acquired.

• Passenger charges.Passenger charges for international passengers are currently denominated in dollars, while passenger charges for domestic passengers are denominated in pesos. Because, through 2007, MFRS required Mexican companies to restate their results of operations in prior periods in constant pesos as of the most recent balance sheet date, when the rate of inflation in a period exceeds the depreciation of the peso as compared to the dollar for that period, the peso value of dollar-denominated or dollar-linked revenues in the prior period is higher than those of the current period. This effect may occur despite the fact that the amount of such revenues in dollar terms may have been greater in the current period.

• Comprehensive financing result (cost).As required by MFRS, our comprehensive financing cost reflects gains or losses from foreign exchange, gains or losses from monetary position (through 2007) and gains and losses from interest. As a result, it is impacted by both inflation and currency depreciation.

• Maximum rates in pesos.Our tariffs for the services we provide to international flights or international passengers are denominated in U.S. dollars, but are generally paid in Mexican pesos based on the average exchange rate for the month prior to each flight. We generally collect passenger charges from airlines 60-115 days following the date of each flight. We intend to charge prices that are as close as possible to the maximum rates that we can charge. Since we are

93

usually only entitled to adjust our specific prices once every six months (or earlier upon a cumulative increase of 5% in the Mexican producer price index, excluding petroleum), a depreciation of the peso as compared to the dollar, particularly late in the year, could cause us to exceed the maximum rates at one or more of our airports, possibly leading to the termination of one of our concessions. In the event that any one of our concessions is terminated, our other concessions may also be terminated. In addition, if the peso appreciates as compared to the dollar we may underestimate the specific prices we can charge for regulated services and be unable to adjust our prices upwards to maximize our regulated revenues.

In accordance with the new Financial Reporting Standard (“NIF”) B-10 “Effects of Inflation”, since the cumulative inflation in Mexico measured by the Mexican Consumer Price Index in the three-year period ended December 31, 2007 was below 26%, we ceased recognizing the effects of inflation in our financial statements for the fiscal year beginning January 1, 2008.

Historically, our most profitable airports have been our Los Cabos, Guadalajara and Puerto Vallarta international airports, which handle the majority of our international passengers. We determine profitability per airport by dividing income from operations at each airport by total revenues for that airport. Operating margins at our Tijuana International Airport historically have been lower than at our other airports because the maximum rates applicable to aeronautical services provided at our Tijuana International Airport are lower than those applicable to our other principal airports. In addition, the amortization of our concession relative to the level of revenues is much higher at our Tijuana International Airport than at our other principal airports.

Results of operations for the year ended December 31, 2007 compared to the year ended December 31, 2006.

Revenues

Total revenues for 2007 increased 14.2%, from Ps. 3,046.2 million in 2006 to Ps. 3,477.3 million in 2007. This increase was mainly due to a 13.4% increase in aeronautical services revenues and a 17.4% increase in non-aeronautical services revenues.

Aeronautical services revenues increased 13.4%, from Ps. 2,480.2 million in 2006 to Ps. 2,812.9 million in 2007. This increase was due primarily to increased revenues from passenger charges fees, which increased Ps. 355 million, driven by a 14.9% increase in total passenger traffic (representing 106.7% of the increase in aeronautical services revenues and 82.3% of the increase in total revenues). However, this increase was partially offset by the decline of Ps. 37.2 million in revenues from airplane landing, parking fees and boarding fees, a decrease of 11.9% compared to 2006. This was the result of the incentives offered to all airlines to attract new routes and frequencies to and from our airports.

As a result of the aforementioned and according to the concession agreements for the recognition of the effect of inflation and the application of the efficiency factor, both under the maximum tariff, aeronautical revenues per passenger decreased 0.3%, from Ps. 112.1 in 2006 to Ps. 111.7 in 2007.

Non-aeronautical services revenues for 2007 increased Ps. 98.5 million, or 17.4% compared to 2006. This increase is mainly attributable to revenues derived from the leasing of space to timeshare developers, which increased Ps. 23.1 million, revenues from parking spaces, which rose by Ps. 21.3 million, revenues from the leasing of commercial spaces, which increased Ps. 21.2 million, and revenues from the leasing of space to food and beverage vendors, which increased by Ps. 10.3 million. These increases led to overall growth in commercial revenues of Ps. 97.9 million, or 25.4% when compared to 2006 (which represented an increase in non-aeronautical service revenues of 77.0% and 17.6% of the total revenue increase). Overall revenue from non-aeronautical services per passenger during 2007 was Ps. 28.2, compared to Ps. 27.6 in 2006, an increase of 2.2%.

Operating Costs

Cost of Services

Cost of services for 2007 increased by Ps. 79.4 million, or 10.4%, from Ps. 759.7 million in 2006 to Ps. 839.1 million in 2007, mainly due to a Ps. 15.0 million increase in the cost of airport maintenance and due primarily to a total provision of Ps. 46.3 million for the employee transfer under which unionized employees of each of our subsidiary airport companies were transferred to a new subsidiary,Corporativo de Servicios Aeroportuarios, S.A. de C.V.,effective January 1, 2008. We believe the employee transfer, which did not affect workers’ rights under applicable collective bargaining agreements, is expected to provide for more equitable compensation among our workforce at different airports as well as more consistent employee costs going forward.

97

Technical Assistance Fee and Concession Tax

The technical assistance fee increased 15.2%, from Ps. 109.3 million in 2006 to Ps. 125.9 million in 2007, mainly because, operating income, as a percentage of the Company’s revenues, grew more than operating expenses. As a result of increased revenues, government concession fees increased by 14.2%, from Ps. 151.3 million in 2006 to Ps. 172.8 million in 2007.

Depreciation and Amortization

Depreciation and amortization increased 1.3%, from Ps. 744.1 million in 2006 to Ps. 754.1 million in 2007, mainly due to the 5.2% increase in depreciation due to the increase in our infrastructure to fulfill the master development programs and our commitment to provide better services to our clients. The concession’s amortization did not report any change.

Income from Operations

Operating income increased 23.7%, from Ps. 1,281.7 million in 2006 to Ps. 1,585.4 million in 2007.

Our operating margin increased 340 basis points, from 42.1% in 2006 to 45.6% in 2007, mainly due to our increase in revenues, offset by the increase in operating expenses.

The main airports that contributed to the increase in income from operations for the year ended December 31, 2007 were Tijuana (income from operations increased 71.3%, from 101.6 million to Ps. 172.9 million and the operating margin increased 38.6%, from 26.2% to 36.2%), Guadalajara (income from operations increased 30.8%, from Ps. 477.2 million to Ps. 624.2 million and the operating margin increased 13.5%, from 47.2% to 53.7%), Los Cabos (income from operations increased 3.7%, from Ps. 324.9 million to Ps. 337.0 million and the operating margin decreased 5.2% from 63.9% to 60.6%) and Puerto Vallarta (income from operations increased 10.2%, from Ps. 256.7 million to Ps. 282.8 million and the operating margin increased 0.5%, from 53.0% to 53.5%). The improvement in Tijuana and Guadalajara was mainly a result of an increase in passenger traffic volumes, and to cost controls. In the case of Puerto Vallarta there were only slight changes in operating margins.

Comprehensive Financing Result

The comprehensive financing result in 2007 increased by Ps. 67.1 million, or 223.2%, reaching an income of Ps. 97.3 million compared to the Ps. 30.2 million comprehensive financing income reported in 2006. This increase was derived from the interest gained on financial investments, which generated Ps. 26.4 million more than the previous year, but mainly due to recognizing the Ps. 68.5 million update of the Asset Tax that will be recovered according to the new IETU Tax Law. These increases were offset by an interest expense of Ps. 20.1 million incurred in 2007 corresponding to the credit facility signed during the year for the financing of the master development plan projects at the Los Cabos, Puerto Vallarta, Hermosillo and Guanajuato Airports.

98

Income Taxes and Asset Tax

Income taxes for 2007 resulted in a charge of Ps. 277.6 million, which consists of the following: a) taxes paid for the year of Ps. 492.9 million, b) minus the benefit from the asset tax recovery of Ps. 286.4 million, stemming from the new Mexican Tax Law IETU, which became effective January 1, 2008, c) plus cancellation of recoverable income tax of Ps. 42.8 million and d) plus deferred income tax of Ps. 28.3 million. The effective tax rate for the Company decreased from 29.3% in 2006 to 16.5% for 2007. This decrease was mainly driven by the aforementioned factors, as well as due to the 28.1% increase in income before taxes.

Net Income

Net income increased Ps. 474.8 million due to the improvement in operating results, previously mentioned, as well due to the benefit in the comprehensive financing result. The Company’s net income increased 51.2%, from Ps. 928.0 million in 2006 to Ps. 1,402.8 million in 2007. Net margin increased from 30.5% in 2006 to 40.3% in 2007, due to the aforementioned factors.

Results of operations for the year ended December 31, 2006 compared to the year ended December 31, 2005.

Revenues

Total revenues for 2006 reached Ps. 3,046.2 million, 8.9% higher than the Ps. 2,797.6 million recognized in 2005, reflecting increases in aeronautical services revenues of 8.7% and non-aeronautical services revenues of 9.6%.

Aeronautical services revenues increased 8.7% from Ps. 2,281.1 million in 2005 to Ps. 2,480.2 million in 2006, due principally to a 7.2% increase in terminal passenger traffic and due to a lesser extent to a 2.2% increase in our maximum rates. As a result of these factors, aeronautical revenue per workload unit increased 1.2% from Ps. 110.8 in 2005 to Ps. 112.2 in 2006.

Non-aeronautical services revenues increased Ps. 49.5 million, or 9.6% compared to 2005. Revenues from food and beverage operations, retail shops, parking, advertising, leasing of commercial space, leasing of space to car rental companies and “duty paid” and “duty-free” shops together represented 98.5% (Ps. 48.8 million) of the increase. However, offsetting this amount was a Ps. 4.2 million decline in revenues from the leasing of space to time-share developers mainly due to the fact that the Los Cabos airport received a one-time payment of Ps. 21.7 million from the leasing of space to time-share developers during 2005. Non-aeronautical revenue per passenger was Ps. 27.6, compared to Ps. 27.0 in 2005, an increase of 2.2%.

99

Operating Costs

Cost of Services

Cost of services increased 8.1% in 2006 compared to 2005, principally due to an increase in utility costs of 18.1%, which was mainly a result of an increase in the price of electricity and an increase in the consumption of electricity caused by the development of our infrastructure at the airports under our master development programs. Also, there was a 23.3% increase in other costs of services, due mainly to auditor fees associated with our activities to ensure compliance with the Sarbanes-Oxley Act of 2002 and technical consulting fees. Meanwhile, maintenance decreased 3.2% and personnel costs increased 4.7%, compared to 2005. As a percentage of total revenues, cost of services decreased by 0.7%, from 25.1% in 2005 to 24.9% in 2006. Cost of services per workload unit increased 0.6% compared to 2005, from Ps. 34.1 in 2005 to Ps. 34.3 in 2006.

Technical Assistance Fee and Concession Tax

The technical assistance fee increased 9.6% from Ps. 99.7 million in 2005 to Ps. 109.3 million in 2006, due to the higher income from operations reported in 2006. Government concession taxes increased 8.9% from Ps. 138.9 million in 2005 to Ps. 151.3 million in 2006, reflecting the higher revenues earned in 2006.

Depreciation and Amortization

The 11.7% increase in depreciation and amortization, from Ps. 666.3 million in 2005 to Ps. 744.2 million in 2006, was due primarily to a 68.4% increase in depreciation, from Ps. 113.8 million in 2005 to Ps. 191.7 million in 2006, which, in turn, was due mainly to a 53.0% increase in our buildings, building improvements, machinery and equipment in 2006. Furthermore, in 2006, we experienced accelerated amortization of certain building improvements realized at our airports in previous years, which were replaced in 2006, prior to the expiration of their expected useful life, which amounted to Ps. 35.8 million, representing 46.0% of the total increase. Amortization of the concessions remained unchanged.

Income from Operations

Income from operations increased 7.7%, from Ps. 1,190.1 million in 2005 to Ps. 1,281.7 million in 2006. The operating margin declined in 2006, from 42.5% in 2005 to 42.1%. This decline reflected the slight increase in total operating costs relative to total revenues, these having increased by 9.8% and 8.9%, respectively.

The main airports that contributed to the increase in income from operations for the year ended December 31, 2006 were Tijuana (income from operations increased 27.3%, from 79.8 million to Ps. 101.6 million and the operating margin increased 3.6%, from 22.6% to 26.2%), Guadalajara (income from operations increased 13.4%, from Ps. 420.8 million to Ps. 477.2 million and the operating margin decreased 0.1%, from 47.3% to 47.2%), Los Cabos (income from operations increased 10.1%, from Ps. 295.0 million to Ps. 324.9 million and the operating margin increased 0.6% from 63.3% to 63.9%) and Puerto Vallarta (income from operations increased 9.4%, from Ps. 234.6 million to Ps. 256.7 million and the operating margin increased

100

0.1%, from 52.9% to 53.0%). The improvement in Tijuana was mainly a result of an increase in revenues, and to a lesser extent to cost controls. In the cases of Guadalajara, Los Cabos and Puerto Vallarta there were only slight changes in operating margins.

Comprehensive Financing Result

In 2006, we recorded comprehensive financing income of Ps. 30.1 million, as compared to Ps. 12.5 million in 2005, representing a 141.8% increase. This increase resulted from a variation in results from embedded derivatives, in respect of which we recorded a loss of Ps. 21.9 million in 2005, as compared to a gain of Ps. 1.9 million in 2006, as well as the 1.7% depreciation of the Mexican peso against the U.S. dollar in 2006, which, in view of our possession of dollar-denominated assets, led to an exchange rate gain of Ps. 5.6 million in 2006, as compared to an exchange rate loss of Ps. 11.7 million in 2005. In 2006, we also benefited from the Ps. 18.7 million recorded as a result of the resolution, in October 2006, in respect of six of our airports, of our asset tax dispute with the Mexican Treasury Department. Offsetting these gains was our loss on monetary position, which increased 8.4% in 2006, as compared to 2005, due to an increase in inflation and a greater position in monetary assets, as well as a 39.5% reduction in interest on investment securities, which interest declined by Ps 19.0 million in 2006 due to a reduction in Mexican domestic interest rates and a 21% lower average cash balance in 2006, as compared to 2005.

Income Taxes and Asset Tax

The provision for income taxes and asset tax declined 21.4% in 2006, to Ps. 384.1 million from Ps. 489.7 million in 2005, due mainly to the resolution, in October 2006, in respect of certain of our airports, of our asset tax dispute with The Mexican Treasury Department, which produced a benefit of Ps. 119.5 million (144.8 million nominal pesos) to our valuation allowance. Our effective tax rate declined from 40.8% in 2005 to 29.3% in 2006, reflecting, in addition to the foregoing, the increase in earnings before taxes of 9.3%.

Net Income

Net income increased 30.5% when compared to 2005, from Ps. 711.3 million to Ps. 928.0 million in 2006, while the net margin increased from 25.4% to 30.5%, due to the aforementioned factors.

Liquidity and Capital Resources

Historically, our operations had been funded through cash flow from operations, and we had not incurred any significant indebtedness until 2007. The cash flow generated from our operations has generally been used to fund operating costs and capital expenditures, including expenditures under our master development programs, and the excess of our cash flow has been added to our accumulated cash balances. In addition, in 2005, 2006 and 2007, we used Ps. 1,136.0 million, Ps. 774.3 million and Ps. 1,171.6 million, respectively, of our cash balances for the payment of dividends.

At December 31, 2006 and 2007, we had Ps. 1,060.7 million and Ps. 1,666.1 million, respectively, of cash, cash equivalents and financial investments held for trading purposes. This

101

increase was due in part to existing funds from a bank loan of Ps. 346.4 million (in connection with the credit agreement described below), which is expected to be used for capital expenditures in 2008. We believe our working capital and resources expected to be generated from operations, in conjunction with the proceeds from the credit agreement described below, will continue to meet our present requirements.

We executed an unsecured peso-denominated credit agreement with Banco Nacional de México (Banamex) on August 31, 2007, which provides financing in an amount of Ps. 1,214.0 million, which we expect to use to fund capital expenditures that we anticipate undertaking through January 2009 at our Los Cabos, Puerto Vallarta, Hermosillo and Guanajuato international airports. This amount will be available for disbursement in three separate tranches as follows: (i) Ps. 600.0 million which was available on September 7, 2007, (ii) Ps. 344.0 million at any time prior to January 31, 2008, and (iii) Ps. 270.0 million at any time prior to January 31, 2009.

On September 7, 2007, we borrowed the first available tranche of Ps. 600.0 million as follows: the Los Cabos airport borrowed Ps. 330.0 million, the Puerto Vallarta airport borrowed Ps. 193.0 million, the Hermosillo airport borrowed Ps. 44.0 million and the Guanajuato airport borrowed Ps. 33.0 million. The borrowings mature in seven years from the date of the borrowing and bear a fixed interest rate of 8.52% on unpaid balances. Interest payments and amortization of principal are required to be made in 28 equal and consecutive quarterly payments. We paid the first amortization of principal and interest on December 7, 2007. We have to comply with the following covenants, among others: (i) limitation on the use of proceeds for the financing of capital expenditures and working capital, (ii) restriction on the incurrence of other debt by any subsidiary, (iii) prohibition on the merger of our Company (or any of its subsidiaries) with any other company, (iv) prohibition on the sale or transfer of assets in an amount greater than Ps. 1.0 million, without previous authorization from Banamex, (v) maintenance of certain financial ratios and (vi) prohibition of dividends in case the airports are unable to fulfill their obligations under the credit agreement.

In 2007, we generated Ps. 2,020.2 million from operating activities, as compared to Ps. 1,525.5 million in 2006, principally reflecting an increase in our income from operations discussed above after taking into consideration non-cash charges such as depreciation, amortization and deferred income tax. Income generated from operations was mainly used to make a dividend payment of Ps. 837.7 million on May 18, 2007 and Ps. 333.9 on October 31, 2007, as well as to invest approximately Ps. 932.3 million in machinery and equipment and improvements to our airport facilities.

On January 25, 2006, we entered into a line of credit with a financial institution, which provides for the issuance of letters of credit up to an aggregate amount of Ps. 300 million in order to guarantee all amounts claimed by municipal authorities and referred to in Note 18.b to our audited consolidated financial statements. Until the line of credit expires in 2009, our airports will be subject to certain financial covenants thereunder, including, among others, the requirement to (i) maintain a consolidated tangible net worth (defined as stockholders’ equity less intangible assets (including airport concessions) and reserves for inflationary effects, in each case under MFRS) of at least Ps. 2,100 million, (ii) maintain a free and unencumbered cash reserve equal to the amount due on any outstanding letter of credit and (iii) earn consolidated

102

annual EBITDA (as defined in the credit agreement) of at least Ps. 1,000 million. On February 9, 2006, an irrevocable standby letter of credit was issued in respect of the Tijuana tax claim in the amount of Ps. 141.8 million (nominal value). The standby letter of credit was granted to the bond institution that issued the bond to municipal authorities in Tijuana in order to release the encumbrance described in Note 18.b to our audited consolidated financial statements.

Under the terms of our concessions, each of our subsidiary concession holders is required to present a master development program for approval by the Ministry of Communications and Transportation every five years. Each master development program includes investment commitments (including capital expenditures and improvements) applicable to us as concession holder for the succeeding five-year period. Once approved by the Ministry of Communications and Transportation, these commitments become binding obligations under the terms of our concessions. In December 2004, the Ministry of Communications and Transportation approved our master development programs for each of our airports for the 2005 to 2009 period. These 5-year programs will be in effect from January 1, 2005 until December 31, 2009.

The following table sets forth our historical capital expenditures, which reflect our actual expenditures (as compared to our committed investments, which are presented further below), by airport, for the years indicated. The substantial majority of these investments were made under the terms of our master development programs.

The following table sets forth our historical capital expenditures by type of investment across all of our airports for the years indicated:

Historical Capital Expenditures by Type

	Year ended December 31,
	2005		2006		2007
	(thousands of pesos)
Terminals	Ps.	247,678	Ps.	171,931	Ps.	406,804

Total	Ps.	634,210	Ps.	665,760	Ps.	931,617

Our capital expenditures from 2005 through 2007 were allocated to the following types of investments at the majority of our airports:

• Terminals.We remodeled many of the terminals at our airports by expanding departure areas (concourses and lounges), baggage claim areas and arrival areas, by improving lighting systems, adding office space, adding taxi and other ground transportation waiting areas, and by increasing handicap services and remodeling our restrooms.

• Runways and aprons.We improved the lighting systems on our runways and access roads, expanded our aircraft parking areas, and made improvements and renovations to the fences on the outlying areas of our properties subject to our concessions.

• Acquisition of long-term leases.Prior to 1999, our predecessor entered into several contracts with third-party operators to develop new space and modernize existing space at our 12 airports. Several of these contracts were long-term lease agreements pursuant to which the third-party service provider, in exchange for assuming all risks during the construction and modernization phase of each development project, acquired the exclusive right to operate the new commercial areas once developed. Many of the most lucrative commercial areas within our principal airports were leased by our predecessor to third parties on a long-term basis.

In some cases these long-term leases also gave the third-party operator the right to operate not only commercial activities, but also passenger walkways, transportation and other activities in the commercial areas subject to the lease. We acquired our concessions from our predecessor subject to these long-term lease obligations and have sought to recover the third parties’ lease rights. In recent

104

years we have recovered, by compensating lease holders for early termination of their leases, several significant leases previously held by third parties who managed our commercial areas and received all revenues from the operations in those areas. We now manage several of those areas directly and have thereby increased our revenues from commercial activities.

We recovered the right to operate commercial space and to collect access fees from certain service providers at our Puerto Vallarta and Guadalajara international airports. These rights were previously scheduled to expire between 2010 and 2011, and include rights to the operation of virtually all of the commercial activities (including stores and office space), as well as passenger taxis and air bridges within at these airports.

• Machinery and equipment.We invested in machinery and equipment such as fire extinguishing vehicles, emergency back-up electricity generators, metal detectors and other security-related equipment, ambulances, moving walkways and public information systems.

• Other.We installed sewage treatment plants and systems at several of our airports, improved our drainage systems, and installed underground electric wiring systems at several of our airports.

The following table sets forth our estimated committed investments for each airport for 2005 through 2009 under our master development programs. These amounts are based on investment commitments approved by the Ministry of Communications and Transportation and have been adjusted by us to take into consideration increases in petroleum and steel prices since the Ministry’s approval. We are required to comply with the investment obligations under these programs on a year-by-year basis. For a discussion of the regulations applicable to our compliance with our master development programs, see “Regulatory Framework—Master Development Programs.”

(3) Variations in estimated committed investment amounts reported by us from time to time are the result of changes in the allocation of investment amounts to different airports and revisions to, and deferrals of, investments in baggage screening systems, which investments cannot be finalized until we reach a definitive agreement with our various airline customers.

In 2005, the Mexican government issued a policy letter calling for all checked baggage on international commercial flights beginning in January 2006, and on domestic commercial flights beginning in July 2006, to undergo a new comprehensive screening process. Because of uncertainty over the policy letter’s implementation, the new screening process has been delayed. In particular, the policy letter does not specify which parties should bear responsibility for the new screening process. Although the Mexican Airport Law clearly specifies that airlines bear the responsibility for baggage screening, the fact that the policy letter is silent as to responsibility has caused some of our airline customers to contend that the policy letter’s intent is for airport concessionaires, such as us, to bear responsibility for the new screening process. In addition, certain questions have been raised regarding the constitutionality of the new screening process. The Mexican Bureau of Civil Aviation is expected to issue regulations implementing the policy letter, but these may not address the questions of responsibility and constitutionality that have been raised. We maintain that the new policy will not be implemented at our airports until we enter into a written agreement with our airline customers regarding the allocation of cost and responsibility. We hope to reach a definitive agreement with our airline customers regarding the allocation of costs and then proceed with the purchase and installation of new equipment.

Differences between estimated committed investments and historical capital expenditures are due primarily to our not having yet installed this baggage screening equipment. The installation of the new equipment was originally contemplated under our master development programs, but as a result of the issues outlined above, we do not believe that we are, or at any time have been, in legal breach of our Master Development Programs.

107

We expect to continue funding the majority of our operations in the short-term and long-term through cash flow from operations, although we have incurred indebtedness. We expect to allocate a majority of our investments for the period 2005 through 2009 to our five largest airports. In particular, a portion of our investments is being dedicated to expanding and remodeling the Guadalajara, Puerto Vallarta and Los Cabos international airports terminals.

Critical Accounting Policies

We prepare our audited consolidated financial statements in conformity with MFRS. As such, we are required to make estimates, judgments and assumptions that affect (i) certain reported amounts of our assets and liabilities, (ii) the disclosure of our contingent assets and liabilities at the date of the financial statements and (iii) certain reported amounts of revenues and expenses during the reporting period. We base our estimates and judgments on our historical experience and on various other reasonable factors that together form the basis for making judgments about the carrying values of our assets and liabilities. Our actual results may differ from these estimates under different assumptions or conditions. We evaluate our estimates and judgments on an ongoing basis. Our significant accounting policies are described in Note 3 to our audited consolidated financial statements.

We believe our most critical accounting policies that result in the application of estimates and/or judgments are the following:

Income Taxes

In conformity with Bulletin D-4, “Accounting for Income Tax, Asset Tax and Statutory Employee Profit Sharing”, of MFRS, we recognize deferred tax assets and liabilities based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities. At December 31, 2007, we recorded, within the long-term deferred income tax asset, an estimated amount of recoverable asset tax paid, based on financial projections that show that we will recover the excess of asset tax over income tax relating to our Guanajuato, Guadalajara, Morelia, Puerto Vallarta and Tijuana airports. As a result of changes in Mexican tax law, the asset tax balance may be recovered through rebates of up to 10% of the total asset tax paid out and pending recovery over the next ten years, provided that this sum does not exceed the difference between the income tax paid during the period and the asset tax paid during the three previous years, whichever is lower, whenever the income tax exceeds asset tax in any of those years. Additionally, we have recorded a tax loss carryforward, expiring on 2048 as permitted by the Mexican tax authorities for concession operation relating to our Aguascalientes, La Paz and Mexicali airports. We regularly review our deferred tax assets for recoverability and, if necessary, establish a valuation allowance based on historical taxable income, projected future taxable income and related income tax expense compared to future estimated asset tax and the expected timing of the reversals of existing temporary differences. If these estimates and related assumptions change in the future, we may be required to make additional adjustments to our deferred tax assets, which may result in a reduction of, or an increase in, income tax expense.

Beginning October 2007, and according to Interpretation of Financial Reporting Standard (“INIF”) 8, “Effects of the Business Flat Tax”, based on its financial projections, the Company must determine whether it will incur regular income tax or the new Business Flat Tax (“IETU”) and, accordingly, recognize deferred taxes based on the tax it expects to pay.

108

Impairment in the Value of Long-Lived Assets

We must test for impairment when indicators of potential impairment in the carrying amount of tangible and intangible long-lived assets in use exist, unless there is conclusive evidence that the indicators of impairment are temporary. An impairment is recorded when the carrying amount of long-lived assets exceeds the greater of the present value of future net cash flows provided by the assets on the net sales price upon disposal. Present value of future net cash flows is based on management’s projections of future operations, discounted using current interest rates. Our evaluations throughout the year and up to the date of this filing did not reveal any impairment of tangible and intangible long-lived assets. We can give no assurance that our evaluations will not change as a result of new information or developments which may change our future projections of net cash flows or the related discount rates and result in future impairment charges.

Principal Differences Between MFRS and U.S. GAAP

Our audited consolidated financial statements are prepared in accordance with MFRS, which differs in certain respects from U.S. GAAP. See Note 24 to our audited consolidated financial statements for a discussion of these differences. Consolidated net income under U.S. GAAP was Ps. 959.3 million, Ps. 1,141.3 million and Ps. 1,756.8 million for the years ended December 31, 2005, 2006 and 2007, respectively.

The principal differences between MFRS and U.S. GAAP as they relate to us are the treatment of our investments in our concessions and the rights to use our airport facilities, the recognition of the fair value of embedded derivatives, the treatment of AMP’s portion of shares held in trust, which are forfeitable, and the effects of these adjustments on deferred income taxes. Each of these differences affects both consolidated net income and stockholders’ equity.

Off-balance Sheet Arrangements

We are not party to any off-balance sheet arrangements.

We have submitted a formal request to the Ministry of Communications and Transportation seeking confirmation that the correct index to be applied to update the amounts set forth in our master development programs is instead the Mexican producer price index. Should the Ministry of Communications and Transportation approve our request, each of the figures set forth in the table above would be reduced by approximately 6%.

(2) Reflects a minimum fixed annual payment of U.S.$ 4.0 million required to be paid under our technical assistance agreement, assuming an average exchange rate of Ps. 10.9169 per U.S. dollar and an annual U.S. inflation rate of 2.7%. The amount ultimately to be paid in any year will depend on our profitability.

(3) Includes leasing of buildings and vehicles.

(4) Amount for less than one year corresponds to obligations for 2008.

(5) The difference between this amount and the amount for 2006 in the table titled “Estimated Committed Investments by Type” above reflects baggage screening equipment that was provided for in our master development programs for 2005 but which we did not purchase in 2005, and have therefore carried forward.

(6) In the fifth year of the master development programs, a negotiation will take place with the Ministry of Communications and Transportation to determine the new master development program commitments for the subsequent five-year period.

New Accounting Pronouncements

MFRS

In 2007, the Mexican Board for Research and Development of Financial Information Standards (CINIF) issued the following NIFs and INIFs, which became effective for fiscal years beginning on January 1, 2008:

NIF B-2,Statement of Cash Flows

NIF B-10,Effects of Inflation

NIF B-15,Translation of Foreign Currencies

NIF D-3,Employee Benefits

NIF D-4,Taxes on Income

INIF 5,Recognition of the Additional Consideration Agreed to at the Inception of a Derivative Financial Instrument to Adjust it to Fair Value

INIF 6,Timing of Formal Hedge Designation

110

INIF 7,Application of Comprehensive Income or Loss Resulting From a Cash Flow Hedge on a Forecasted Purchase of a Non-Financial Asset

Some of the significant changes established by these standards are as follows:

NIF B-2, Statement of Cash Flows. This NIF establishes general rules for the presentation, structure and preparation of a cash flow statement, as well as the disclosures supplementing such statement, which replaces the statement of changes in financial position. NIF B-2 requires that the statement show a company’s cash inflows and outflows during the period. Line items should be preferably presented gross. Cash flows from financing activities are now presented below those from investing activities (a departure from the statement of changes in financial position). In addition, NIF B-2 allows entities to determine and present their cash flows from operating activities using either the direct or the indirect method.

NIF B-10, Effects of Inflation. NIF B-10 defines two economic environments: a) inflationary environment, when cumulative inflation of the three preceding years is 26% or more, in which case, the effects of inflation should be recognized using the comprehensive method; and b) non-inflationary environment, when cumulative inflation of the three preceding years is less than 26%, in which case, no inflationary effects should be recognized in the financial statements. Additionally, NIF B-10 eliminates the replacement cost and specific indexation methods for inventories and fixed assets, respectively, and requires that the cumulative gain or loss from holding non-monetary assets be reclassified to retained earnings, if such gain or loss is realized; the gain or loss that is not realized will be maintained in stockholders’ equity and charged to current earnings of the period in which the originating item is realized.

NIF B-15, Translation of Foreign Currencies. NIF B-15 eliminates classification of integrated foreign operations and foreign entities and incorporates the concepts of accounting currency, functional currency and reporting currency. NIF B-15 establishes the procedures to translate the financial information of a foreign subsidiary: i) from the accounting to the functional currency; and ii) from the functional to the reporting currency, and allows entities to present their financial statements in a reporting currency other than their functional currency.

NIF D-3, Employee Benefits. This NIF addresses current and deferred statutory employee profit sharing (“PTU”). Deferred PTU should be calculated using the same methodology established in Bulletin D-4,Income Taxes, Tax on Assets and Statutory Employee Profit Sharing. It also includes the career salary concept and the amortization period of most items is reduced to a five-year period or less, provided an employees’ remaining labor life is less than the:

• Beginning balance of the transition liability for severance and retirement benefits,

• Beginning balance of past service cost and changes to the plan,

• Beginning balance of gains and losses from severance benefits, according to actuarial calculations, should be amortized against the results of 2008, and the

111

• Beginning balance of gains and losses from retirement benefits, according to actuarial calculations, should be amortized over a five-year period (net of the transition liability), with the option to fully amortize such item against the results of 2008.

NIF D-4, Taxes on Income. This NIF relocates accounting for current and deferred PTU to NIF D-3, eliminates the permanent difference concept, redefines and incorporates various definitions and requires that the cumulative income tax effect be reclassified to retained earnings, unless it is identified with some of the other comprehensive income items that have not been applied against current earnings.

INIF 5, Recognition of the Additional Consideration Agreed to at the Inception of a Derivative Financial Instrument to Adjust it to Fair Value. INIF 5 states that any additional consideration agreed to at the inception of a derivative financial instrument to adjust it to its fair value at that time should be part of the instrument’s initial fair value and not subject to amortization as established by paragraph 90 of Bulletin C-10,Derivative Financial Instruments and Hedging Activities. INIF 5 also establishes that the effect of the change should be prospectively recognized, affecting results of the period in which this INIF becomes effective. If the effect of the change is material, it should be disclosed.

INIF 6, Timing of Formal Hedge Designation. INIF 6 states that hedge designations may be made as of the date a derivative financial instrument is contracted, or at a later date, provided its effects are prospectively recognized as of the date when formal conditions are met and the instrument qualifies as a hedging relationship. Paragraph 51.a) of Bulletin C-10 only considered the hedge designation at the inception of the transaction.

INIF 7, Application of Comprehensive Income or Loss Resulting From a Cash Flow Hedge on a Forecasted Purchase of a Non-Financial Asset. INIF 7 states that the effect of a hedge reflected in other comprehensive income or loss resulting from a forecasted purchase of a non-financial asset should be capitalized within the cost of such asset, whose price is set through a hedge, rather than reclassifying the effect to the results of the period affected by the asset, as required by Paragraph 105 of Bulletin C-10. The effect of this change should be recognized by applying any amounts recorded in other comprehensive income or loss to the cost of the acquired asset, as of the effective date of this INIF.

On November 30, 2006, the International Financial Reporting Interpretations Committee (“IFRIC”) issued IFRIC 12,Service Concession Arrangements. The Interpretation addresses the accounting by private sector operators involved in the provision of public sector infrastructure assets and services, such as schools and roads. The Interpretation does not address the accounting for the government (grantor) side of such arrangements. Accounting for concessions is not specifically addressed in MFRS, for which reason IFRIC 12 will be applied supplementally in the Company’s consolidated financial statements.

U.S. GAAP

In September 2006 the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 157Fair Value Measurements.

112

SFAS 157 defines fair value, establishes a framework for measuring fair value in accordance with U.S. GAAP, and expands disclosures about fair value measurements. This statement clarifies the definition of exchange price as the price between market participants in an orderly transaction to sell an asset or transfer a liability in the market in which the reporting entity would transact for the asset or liability, that is the principal or most advantageous market for the asset or liability. The changes to current practice resulting from the application of this statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 for financial assets and liabilities such as derivatives measured at fair value under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. SFAS No. 157 has been deferred until fiscal years beginning after November 15, 2008 for nonfinancial assets and liabilities such as asset retirement obligations measured at fair value at initial recognition, long-lived asset groups measured at fair value under SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, liabilities for exit or disposal activities measured at fair value under SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities, etc. The adoption of this standard is not expected to have a material impact on Company’s consolidated financial position, results of operations or cash flows.

In February 2007, the FASB issued SFAS No. 159The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115, which permits entities to choose to measure many financial instruments and certain other items at fair value at specified election dates. Unrealized gains and losses on items for which the fair value option has been elected will be recognized in earnings at each subsequent reporting date. SFAS 159 provides entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 is for fiscal years beginning after November 15, 2007. The adoption of this standard is not expected to have a material impact on Company’s consolidated financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141 (revised 2007)Business Combinations, a replacement of FASB No. 141. SFAS 141(R) establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree at fair value as of the acquisition date. The Statement also establishes disclosures requirements which will enable users to evaluate the nature and financial effects of the business combination. SFAS 141(R) is effective for fiscal years beginning on or after December 15, 2008. The Company has not yet determined the impact, if any, of the adoption of FAS 141(R) on its consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161,Disclosures about Derivative Instruments and Hedging Activities, which enhances the current disclosure framework in SFAS No.133, Accounting for Derivative Instruments and Hedging Activities. SFAS No.161 primarily requires (i) qualitative disclosures about objectives and strategies for using derivatives in the context of each instrument’s primary underlying risk exposure; (ii) quantitative disclosures about the location and fair value amounts of and gains and losses on derivative instruments, in a tabular format; and (iii) disclosures about credit-risk-related contingent features in derivative agreements. This statement is effective for financial statements issued for

113

fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. This Statement encourages, but does not require, comparative disclosures for earlier periods at initial adoption. The Company is in the process of determining the effects of this new standard on its consolidated financial information.

Item 6. Directors, Senior Management and Employees

Directors

The board of directors is responsible for the management of our business. Pursuant to our bylaws, our board of directors generally must consist of 11 members.

None of our directors of executive officers are entitled to benefits upon termination under their service contracts with us, except for what is due them according to the Mexican Federal Labor Law.

Board Committees

Our bylaws provide for four committees to assist the board of directors with the management of our business: an Operating Committee, an Audit Committee, an Acquisitions Committee and a Nominations and Compensation Committee. The Audit Committee, to which our bylaws have granted, as is permitted, the duties provided for in the Securities Market Law for Mexican corporate practices committees, is the only legally required committee. The other committees have been constituted to assist the board of directors. The board of directors may constitute further committees from time to time.

Operating Committee

The Operating Committee, which, pursuant to our bylaws, should have six members, is responsible for, among other matters, proposing and approving certain plans and policies relating to our business, investments and administration, including approval of the Master Development Programs of our subsidiary concession holders, our dividend policy and investments of less than U.S.$ 3.0 million that are not provided for in our annual budget. Pursuant to our bylaws, the board of directors is authorized to appoint the six members of the Operating Committee.

120

Audit Committee

The Audit Committee, which must have a minimum of three members, the majority of whom must be members of our board of directors, is responsible, among other things, for (i) monitoring the compliance of our directors, officers and employees (and those of our subsidiaries) with our (and their) bylaws (estatutos sociales) and applicable law, (ii) naming, and supervising the work of, our independent auditors and (iii) receiving and investigating internal complaints or other information concerning our systems of internal control and other such matters. This committee is also responsible for reviewing our corporate governance and all related-party transactions (according to the requirements of our bylaws and the Mexican Market Law), including transactions with AMP. The committee also names a special delegate, whose responsibility it is to ensure AMP’s compliance with the technical assistance agreement. The members of the board of directors elected by the holders of Series BB shares are entitled to propose the appointment to the Audit Committee of the number of members representing 20% of the committee’s total members, or at least one member who must also fulfill applicable independence requirements. The president of this committee is elected at the annual stockholders’ meeting. The composition of the Audit Committee must at all times be compliant with all applicable laws and regulations, including independence requirements, in every jurisdiction where our securities are listed or quoted. The current members of the Audit Committee are José Manuel Rincón Gallardo Purón, Francisco Javier Fernández Carvajal and Ernesto Vega Velasco. A secretary has also been appointed, who is not a member of the committee.

Acquisitions Committee

The Acquisitions Committee is responsible for ensuring compliance with our procurement policies set forth in our bylaws. Among other things, these policies require that the Acquisitions Committee approve any transaction or series of related transactions between us and a third party involving consideration in excess of U.S.$ 400,000 and that any contract between us, on the one hand, and AMP or any of its related persons, on the other hand, be awarded pursuant to a bidding process, which, in the case of AMP, must involve at least three other bidders. Our bylaws provide that a stockholders’ meeting will determine the number of members of the Acquisitions Committee, which must be composed primarily of members of the board of directors. The members of the board of directors elected by the holders of Series BB shares are entitled to appoint to the committee the number of members representing 20% of its total members. The members of the Acquisitions Committee are Carlos Del Río Carcaño, Alfonso Pasquel Bárcenas and Eduardo Sánchez Navarro Redo who has been elected to serve as an alternate member to Carlos del Río Carcaño beginning April 28, 2008. A secretary has also been appointed who is not a member of the committee. In the case of a proposed transaction between us and AMP or any related party, we are required to invite, pursuant to the bylaws, at least three contractors to bid on the transaction and, in the case that a third-party contractor’s bid is equal to or less than AMP’s bid, the transaction is awarded to the third-party contractor.

Nominations and Compensation Committee

The Nominations and Compensation Committee is responsible for nominating candidates for election to our board of directors and making recommendations regarding the

121

compensation of our directors and officers. The committee also serves in a corporate governance role within its subject-matter ambit.

NYSE Corporate Governance Comparison

Pursuant to Section 303A.11 of the Listed Company Manual of the New York Stock Exchange, we are required to provide a summary of the significant ways in which our corporate governance practices differ from those required for listed U.S. companies under Section 303A of such manual. We are a Mexican corporation with shares listed on the Mexican Stock Exchange. Our corporate governance practices are governed by our bylaws, the Securities Market Law and the regulations issued by the Mexican Banking and Securities Commission (Comisión Nacional Bancaria y de Valores). We also generally comply on a voluntary basis with the Mexican Code of Best Corporate Practices (Código de Mejores Prácticas Corporativas), which was created in January 2001 by a group of Mexican business leaders and was endorsed by the Mexican Banking and Securities Commission. On an annual basis, we file a report with the Mexican Banking and Securities Commission and the Mexican Stock Exchange regarding our compliance with the Mexican Code of Best Corporate Practices.

On December 30, 2005, the new Securities Market Law was published in the Mexican Federal Gazette, and it became effective on June 28, 2006.

The table below discloses the significant differences between our corporate governance practices and the NYSE standards.

NYSE Standards for Domestic Listed Companies1	Our Corporate Governance Practices
Director Independence.
§303A.01 specifies that listed companies must have a majority of independent directors.	Pursuant to the Securities Market Law and Article 15 of our bylaws, at least 25% of the members of our board of

¹ References to sections are references to sections of the New York Stock Exchange Listed Company Manual. Pursuant to Section 303A.00 thereof, foreign private issuers, such as us, are exempt from the corporate governance standards of the exchange, with certain exceptions.

122

NYSE Standards for Domestic Listed Companies1

Our Corporate Governance Practices

To qualify as independent, a director must satisfy the criteria set forth in §303A.02. In particular, a director is not independent if such director is: (i) a person who the board determines has a material direct or indirect relationship with the company, its parent or a consolidated subsidiary; (ii) an employee, or an immediate family member of an executive officer, of the company, its parent or a consolidated subsidiary, other than employment as interim chairman or CEO; (iii) a person who receives, or whose immediate family member receives, more than $100,000 per year in direct compensation from the company, its parent or a consolidated subsidiary, other than director and committee fees or deferred compensation for prior services only (and other than compensation for service as interim chairman or CEO or received by an immediate family member for service as a non-executive employee); (iv) a person who is affiliated with or employed, or whose immediate family member is affiliated with or employed in a professional capacity, by a present or former internal or external auditor of the company, its parent or a consolidated subsidiary; (v) an executive officer, or an immediate family member of an executive officer, of another company whose compensation committee’s membership includes an executive officer of the listed company, its parent or a consolidated subsidiary; or (vi) an executive officer or employee of a company, or an immediate family member of an executive officer of a company, that makes payments to, or receives payments from, the listed company, its parent or a consolidated subsidiary for property or services in an amount which, in any single fiscal year, exceeds the greater of $1 million or 2% of such other company’s consolidated gross revenues (charities are not included, but any such payments must be disclosed in the company’s proxy (or, if no proxy is prepared, its Form 10-K / annual report)).

directors must be independent. Determinations regarding independence must be made by our stockholders applying the provisions of the Securities Market Law and our bylaws (which incorporate Section 10A-3 of the Exchange Act). The determination of independence under the Securities Market Law differs in certain respect from the provisions of §303A.02. Under Article 26 of the Securities Market Law, a director is not independent if such director is: (i) an employee or officer of the company or of another company that is a member of the same corporate group (consorcio o grupo empresarial) as the company (or a person who has been so within the prior year); (ii) a person that, without being an employee or officer of the company, has influence or authority over the company or its officers, or over another company that is a member of the same corporate group as the company; (iii) an important client, supplier, debtor or creditor (or a partner, director or employee thereof). (A client or supplier is considered important if its sales to or purchases from the company represent more than 10% of its total sales or purchases within the prior year. A debtor or creditor is considered important if the aggregate amount of the relevant loan represents more than 15% of its or the company’s aggregate assets; (iv) a stockholder that is a part of the control group of the company; or (v) a family member, spouse or concubine of any of the persons mentioned in (i) through (iv) above. Currently, our board of directors consists of 10 directors. Six of such directors have been qualified as independent by our stockholders in accordance with the Securities Market Law and our bylaws.

123

NYSE Standards for Domestic Listed Companies1	Our Corporate Governance Practices
Executive Sessions. §303A.03 specifies that the non-management directors of each listed company must meet at regularly scheduled executive sessions without management.	Mexican law, our bylaws and the Mexican Code of Best Corporate Practices, which we adhere to, do not provide for non-management executive sessions. None of our managers are members of either our board of directors or our other committees, except that our chief executive officer is the chairman of our Operating Committee, as provided for in Article 27 of our bylaws.
Committees for Director Nominations and Compensation and for Corporate Governance.
§303A.04(a) specifies that listed companies must have a nominating/corporate governance committee composed entirely of independent directors. §303A.05(a) specifies that listed companies must have a compensation committee composed entirely of independent directors.	We have a “Nominations and Compensation Committee.” We also have an Audit Committee, which, pursuant to Article 31 of our bylaws, has been assigned certain corporate governance (prácticas societarias) oversight obligations mandated by the Securities Market Law. Under Mexican corporate law, a corporation’s “board committees,” except for audit and corporate governance committees, need not be composed only of members of the corporation’s board of directors. Article 28 of our bylaws provides that at least a majority of the members of our Nominations and Compensation Committee must be members of our board of directors. No express independence requirements apply to this committee. Currently, the committee consists of 2 members, both of whom are members of our board of directors, and one of whom is independent as defined under the Securities Market Law and Section 10A-3 of the Exchange Act. See below for a description of the composition of our Audit Committee.
Audit Committee.
§303A.06 specifies that listed companies must have an audit committee that satisfies the requirements of Rule 10A-3 under the Exchange Act. §303A.07 specifies other requirements for audit committees.	Foreign private issuers, such as us, are subject to §303A.06 and thus must comply with Rule 10A-3. We are in compliance with Rule 10A-3 and, as such, our Audit Committee consists entirely of members of our board of directors who meet the independence requirements prescribed in that rule. (The Securities Market Law likewise contains a requirement that our Audit Committee be entirely independent.) We are not subject to §303A.07. As such, our Audit Committee charter (contained in Article 32 of our bylaws) does not make provision for every one of the specific duties required by §303A.07.

124

NYSE Standards for Domestic Listed Companies1	Our Corporate Governance Practices
Corporate Governance Guidelines.
§303A.09 specifies that listed companies must adopt and disclose corporate governance guidelines.	Mexican law does not require us to disclose corporate governance guidelines and we have not done so. However, pursuant to the Securities Market Law, we have adopted board guidelines covering corporate governance matters such as the use of corporate assets, certain transactions with related parties (including loans to officers), repurchases of shares, communications with stockholders, managers and directors, and other matters. In addition, we have adopted a corporate code of ethics, which is available on our corporate Internet site.

All of our unionized employees are members of local chapters of the Mexican National Union of Airport Workers (Sindicato Nacional de Trabajadores de la Industria Aeroportuaria y Servicios Similares y Conexos de la República Mexicana), an organization formed in 1998 whose members include employees of the Mexican Airport and Auxiliary Services Agency as well as of the three other airport groups (the Southeast Group, the Mexico City Group and the Central-North Group) operating in Mexico. Labor relations with our employees are governed by 12 separate collective bargaining agreements, each relating to one of our 12 airport subsidiaries, and negotiated by the local chapter of the union. As is typical in Mexico, wages are renegotiated every year, while other terms and conditions of employment are renegotiated every two years. We will next renegotiate our collective bargaining agreements with our unionized employees in 2007. We believe that our relations with our employees are good. We believe the wages we pay our employees are similar to those paid to employees of similar airport operating companies in Mexico.

We maintain a savings plan available to all of our employees pursuant to which our employees may make bi-weekly contributions of up to 13% of their pre-tax salaries. We make bi-weekly contributions matching each employee’s contribution. Employees are entitled to withdraw the funds in their accounts on an annual basis. In 2006 and 2007, we made a total of Ps. 14.1 million and Ps. 13.8 million, respectively, in payments to employees’ accounts pursuant to the savings plan.

Funds in the savings plan may be used to make loans to employees and are otherwise invested in securities listed on the Mexican Stock Exchange or in treasury bills issued by the Mexican Treasury Department.

AMP holds all of our Series BB shares. Special rights and restrictions attach to our Series BB shares as described under “Item 4, Information on the Company—History and Development of the Company” and “Item, Additional Information—Corporate Governance.” As of June 3, 2008, approximately 81.5% of our Series B shares were held in the form of ADSs.

AMP Trust, Bylaws and Stockholders’ Agreement

The rules governing the sale of our Series BB shares to AMP required that AMP place all of its Series BB shares in trust in order to guarantee AMP’s performance of its obligations under the technical assistance agreement and AMP’s commitment to maintain its interest in us for a specified period. Accordingly, AMP has placed its shares in trust with Bancomext. This trust provides that AMP may instruct Bancomext with respect to the voting of the shares held in trust that represent up to 10% of our capital stock; the remaining 5% is required to be voted in the same manner as the majority of all shares voted at the relevant stockholders’ meeting. Under our bylaws and the trust, AMP could not sell any of its Series BB shares before August 25, 2004. Since the end of this no-sale period, AMP has been permitted to transfer up to 49% of its Series BB shares without restriction. After August 25, 2009, AMP may additionally sell in any year up to 20% of its remaining 51% ownership interest in us represented by Series BB shares. The terms of the trust will be extended for an additional 15 years if, at the end of the initial 15 year term, AMP holds shares representing more than 10% of our capital stock. AMP may terminate the trust before the second 15-year term begins if: (i) AMP holds less than 10% of our capital stock at the end of the initial term; and (ii) the technical services agreement has been terminated. AMP is required to deposit in the trust any additional shares of our capital stock that it acquires.

AMP’s stockholders have entered into a stockholders’ agreement that provides that their right to appoint certain of our executive officers is to be allocated as follows: Controladora Mexicana will have the right to appoint our chief executive officer, AENA will have the right to appoint our director of technical operations, and the appointment of our chief financial officer, director of investor relations, general counsel, director of human resources, director of commercial activities and the secretary of our board of directors will be determined by a simple majority vote of AMP’s stockholders. All other officers, directors or committee members to be appointed by AMP, and most other matters relating to AMP’s participation in us, must be agreed upon by holders of 60% in aggregate of the equity of AMP.

Under the terms of the participation agreement and the trust agreement, AMP’s key partners are required to maintain their current 25.5% ownership interest in AMP until August 25, 2014. To the extent that a key partner acquires shares of AMP in excess of its current 25.5% interest, this additional interest may be sold without restriction. There can be no assurance that the terms of the participation agreement or the trust would not be amended to reduce or eliminate these ownership commitments. If AMP or any of its stockholders defaults on any obligation contained in the trust agreement, or if AMP defaults on any obligation contained in the participation agreement or the technical assistance agreement, after specified notice and cure provisions, the trust agreement provides that the trustee may sell 5% of the shares held in the trust and pay the proceeds of such sale to us as liquidated damages.

RELATED PARTY TRANSACTIONS

Arrangements with AMP and its Affiliates

The rules for the sale of the Series BB shares required AMP, us and the Ministry of Communications and Transportation to enter into a participation agreement, which established the framework for the technical assistance agreement and the Banco Nacional de Comercio Exterior, S.N.C., or Bancomext, trust agreement.

Pursuant to the technical assistance agreement and the participation agreement, AMP and its stockholders agreed to provide management and consulting services and transfer to us technical assistance and technical and industry expertise related to the operation of airports. The agreements have initial terms of approximately 15 years, expiring on August 25, 2014. The technical assistance agreement automatically renews for successive five-year terms unless one party provides the other a notice of termination at least 60 days prior to a scheduled expiration date. A decision by us not to renew the technical assistance agreement is subject to the approval of 51% of Series B stockholders other than AMP or any related party of AMP (to the extent that AMP or any such related party holds Series B shares). The agreement will only remain in effect if AMP continues to hold at least 7.65% of our capital stock.

The technical assistance fee for each of 2000 and 2001 was U.S.$ 7.0 million (adjusted annually for U.S. inflation since August 25, 2000). Subsequent to January 1, 2002, the technical assistance fee has been required to equal the greater of U.S.$ 4.0 million adjusted annually for inflation (measured by the U.S. consumer price index) or 5% of our annual consolidated income from operations (calculated prior to deducting the technical assistance fee and depreciation and amortization and in each case determined in accordance with MFRS). We believe that this structure creates an incentive for AMP to increase our annual consolidated earnings.

The technical assistance agreement allows AMP, its stockholders and their affiliates to render additional services to us only if our Acquisitions Committee determines that these related persons have submitted the most favorable bid in a bidding process. This process is described in “Item 6, Directors, Senior Management and Employees—Committees.”

In 2005, 2006 and 2007, we recognized expenses of U.S.$ 8.7 million, U.S.$ 9.8 million and U.S.$ 11.5 million, respectively, pursuant to the technical assistance agreement plus additional expenses paid to AMP and its affiliates of approximately U.S.$ 5,750, U.S.$ 28,950 and U.S.$ 4,466, respectively.

LEGAL PROCEEDINGS

General

We are involved in certain legal proceedings from time to time that are incidental to the normal conduct of our business. In addition, the Mexican Airport and Auxiliary Services Agency is currently engaged in several legal proceedings related to our airports, none of which is expected to have a material adverse effect on our business.

128

Ejido participants at Tijuana Airport

A portion of the land comprising the Tijuana International Airport was expropriated by the Mexican government in 1970 pursuant to its power of eminent domain. Prior to its expropriation, the land had been held by a group of individuals through a system of communal ownership of rural land known as anejido. The formerejidoparticipants have asserted claims against the Mexican government challenging the 1970 expropriation decree. Our Tijuana airport subsidiary has been joined in the proceedings, but only as an interested third party. Although, a judgment in favor of the formerejidoparticipants could materially disrupt the airport’s current operations, the terms of our concession require the Mexican government to provide restitution to us for any loss of our use of the land subject to our concessions.

Certain of the formerejidoparticipants are currently occupying portions of the real property on which we operate Tijuana International Airport that are not currently essential to the airport’s operations. Although these persons are not currently interfering with the airport’s operations, their presence could limit our ability to expand the airport into the areas they currently occupy. In addition, there can be no assurance that the formerejidoparticipants will not seek to disrupt the airport’s operations if their legal claims against the Mexican government are not resolved to their satisfaction. During 2007, the Ejido received an unfavorable resolution, which it appealed. As of the date of this filing, resolution to the appeal is still pending.

Deductibility of certain payments to the Mexican Airport and Auxiliary Services Agency

Pursuant to a management services agreement, our predecessor, the Mexican Airport and Auxiliary Services Agency agreed to provide certain services to our airports for a temporary transition period in exchange for a management fee of 26.5% of the gross monthly revenues of each of our subsidiary concession holders. Pursuant to the terms of this agreement, the Mexican Airport and Auxiliary Services Agency was only to provide these services until the date on which our strategic stockholder (AMP) acquired its 15% equity interest in our capital stock on August 25, 1999. However, AMP was unable to provide these services starting on August 25, 1999 and, as a result, the Mexican Airport and Auxiliary Services Agency continued to provide these services after August 25, 1999 through November 15, 1999 without an agreed management fee for this period.

An agreement with respect to the management fee owed for the period from August 25, 1999 to November 15, 1999 was not reached between us and the Mexican Airport and Auxiliary Services Agency until early in 2003. Upon reaching this agreement, we paid a total fee of Ps. 70.9 million (including value-added tax (IVA)) for these services. A deduction for this expense was taken in 2003.

One of the requirements under Mexican income tax law to deduct an expense in a fiscal period is that the service be rendered in the same period in which it is deducted. In light of this requirement, we requested confirmation from the Mexican Treasury Department that a

129

deduction for the management fee for the period from August 25, 1999 through November 15, 1999 could be claimed in 2003, since an agreement with respect to the amount of this fee was not reached until 2003. During 2004, the Mexican Treasury Department responded to the request rejecting the criteria for deduction in 2003 proposed by us. In 2004, we initiated an annulment proceeding. In 2005, we received a favorable ruling with respect to the claim relating to our Aguascalientes airport, but received an unfavorable ruling in a first instance on the claims with respect to the Guanajuato, Guadalajara, Tijuana, Puerto Vallarta and Los Cabos airports. Subsequently, during 2006, we received a favorable sentence in the ultimate instance at the La Paz airport and unfavorable sentences in the ultimate instance at the Aguascalientes, Hermosillo, Mexicali and Los Mochis airports. In April 2007, we received a favorable sentence in the ultimate instance at the Manzanillo airport, and, in June 2007, we received an unfavorable sentence in the ultimate instance in Morelia airport. At the Aguascalientes and Morelia airports, the unfavorable sentences were based on the merits of the claim, for which reason the Company has recognized provisions of Ps. 1,336 and Ps. 2,058, respectively, which include penalties and interest; the unfavorable sentences received at the Hermosillo, Mexicali and Los Mochis airports were based on deficiencies in form. With respect to the Guanajuato, Guadalajara, Puerto Vallarta, Los Cabos and Tijuana airports, a higher court has issued a sentence requiring the Mexican Tax Court to issue a new ruling, considering the arguments presented in respect of these airports. If we are unsuccessful in our challenge, we estimate that we would be required to pay approximately Ps. 20.6 million plus accrued surcharges and penalties. Regarding this claim, on April 8, 2008, the Hermosillo airport received a fiscal resolution which requires the airport to pay PTU Ps. 4,322. However, the airport management believes there is no legal basis for this resolution, and accordingly, the Hermosillo airport filed a judicial annulment on April 15, 2008.

Proceedings before the Mexican Treasury Department regarding asset tax

On December 31, 2003, we commenced two administrative proceedings before the Mexican Treasury Department seeking (i) a reduction of the asset basis of, or the applicable rate for purposes of calculating asset tax liability on, our airport concessions, so that such base only includes 15% of the concession value and (ii) an increase of the recovery period of any asset tax paid. Both proceedings seek to reduce our effective tax rate. Based on the advice of our tax advisors, our board of directors agreed during its meeting on April 29, 2004 to commence legal proceedings if the Mexican Treasury Department rejected our position. The Mexican Treasury Department did so and we commenced such proceedings in the Mexican Tax Court.In 2005, the Mexican Tax Court reached the decision to obligate the Mexican Treasury Department to accept our method of calculating the asset tax base or grant us a specific tax benefit. The Mexican Treasury Department appealed this decision in federal court. On May 12, 2006, the federal court with jurisdiction over six of our airports declared the appeal by the Mexican Treasury Department unfounded, finding that it was correct to base the asset tax applicable with respect to the Aguascalientes, Hermosillo, La Paz, Los Mochis, Morelia and Manzanillo airports only on 15% of the value of the concessions at those airports as requested by us (equivalent to AMP’s pro rata interest in those concessions as a result of AMP’s 15% interest in us). As a result of this resolution, on August 29, 2006, the Mexican Treasury Department issued a notice confirming this methodology for those airports. On September 1, 2006, the federal court with jurisdiction over our remaining airports reached the same decision as that reached for the aforementioned six airports. The Mexican Treasury Department has appealed that decision. Currently, we are awaiting the final resolution of the federal court hearing such appeal.

130

As a result of the federal court decision and the final notice delivered to us by the Mexican Treasury Department in respect of our Aguascalientes, Hermosillo, La Paz, Los Mochis, Morelia and Manzanillo airports, in that last quarter of 2006 we recorded the effect of that resolution, which resulted in an overall benefit of Ps. 208.6 million nominal pesos was recognized in the income statement as the reduction of the valuation allowance (see note 16.b of our audited consolidated financial statements). During 2007, we received a refund of Ps. 146.4 related to the airports, resulting in a pending balance of Ps. 62.2 million. At December 31, 2005, 2006 and 2007, the balances in aggregate for all six airports were: (i) asset taxes of Ps. 180.0 million, Ps. 18.5 million and Ps. 27.6 million, respectively; and (ii) a valuation allowance of Ps. 155.5 million, Ps. 16.7 million and Ps. 23.3 million respectively, representing those amounts which we do not expect to recover.

Property tax claims by certain municipalities

Claims have been asserted against us by the municipalities of Mexicali, Los Mochis, Tijuana, Los Cabos and Aguascalientes for the payment of property taxes with respect to the real property on which we operate our airports in those cities, and similar claims may be asserted by other municipalities where we operate our airports. The claims in respect of the Los Mochis International Airport have been dismissed. In the case of Aguascalientes, although we have received a memorandum from the Aguascalientes ministry of finance stating that the Aguascalientes International Airport is exempt from property taxes, we continue to defend the claim in order to obtain a definitive judicial resolution, which we expect will be in our favor. In the case of Los Cabos, we filed for a judicial annulment, after which, in 2006, the municipal authorities retracted their tax claim. We are also seeking the dismissal of remaining claims pending in Mexicali and Tijuana. The total amount of the property-tax claims outstanding in each of Mexicali and Tijuana are Ps. 89.0 million (nominal value) and Ps. 146.4 million (nominal value), respectively, although either of these amounts could increase if the underlying claims are not resolved in our favor as a result of penalty and interest surcharges.

In Tijuana, the court had ordered the temporary encumbrance of certain of our assets, including our concession to operate the Tijuana International Airport, pending our deposit of a bond with the court as provisional security, in accordance with Mexican judicial procedures, pending the final resolution of the underlying claims. As of March 19, 2008, the administrative court resolved to dismiss the claims brought forward by the city council of Tijuana. Although the encumbered assets did not affect the operation of the airport, on February 9, 2006, an irrevocable standby letter of credit was issued by a financial institution on behalf of the Tijuana airport for Ps. 141.8 million (nominal value) in order to release the encumbrance. This amount differs from the original amount of the tax claim because it was an estimate intended to guarantee payment of both the tax and penalties for late payment.

In order to secure this surety bond, or any other future surety bond to challenge any property-tax claims by any other municipality, our airport subsidiaries have entered into a committed credit line with a financial institution. This credit line provides for the issuance of letters of credit up to an aggregate amount of Ps. 300 million. In the event a letter of credit is drawn down and the amount drawn down remains unpaid for more than one business day, the outstanding balance will accrue interest at two times the Mexican interbank rate. Until the credit line expires in 2009, our airport subsidiaries are subject to certain financial covenants,

131

including the requirement to (i) maintain a consolidated tangible net worth (defined as stockholders’ equity less intangible assets (including our concessions) and reserves for inflationary effects, in each case under MFRS) of at least Ps. 2.1 billion, (ii) maintain a free and unencumbered cash reserve equal to the amount due on any outstanding letters of credit and (iii) earn consolidated annual EBITDA of at least Ps. 1.0 billion.

A court has also ordered the temporary encumbrance of 25% of the revenues from the parking garage that we operate at the Mexicali airport to guarantee the property-tax claims of the Mexicali municipal government. The cumulative amount of such encumbrances is Ps. 5.4 million (nominal value). In the event of a decision in our favor in the annulment proceeding that we have initiated with respect to each of those claims, we expect to recover such encumbered revenues in full.

We do not believe that liabilities related to any claims or proceedings against us are likely to have, individually or in the aggregate, a material adverse effect on our consolidated financial condition or results of operations because, should a court determine that these taxes must be paid in response to any future proceedings, we believe that the Mexican government, as the owner of the real property upon which we operate our airports, would be responsible for paying these taxes directly, and the obligation to pay these taxes is not otherwise contemplated in the terms of our concessions. Nonetheless, the Mexican government has indicated publicly that it may propose an amendment to the Mexican Constitution and other laws pursuant to which we could be liable to municipalities for property taxes in the future. If such a change were to occur and any amounts owed were substantial, these tax liabilities could therefore have a materially adverse effect on our consolidated financial condition or results of operations.

Other claims by certain municipalities

In Guadalajara we are subject to claims by the municipality regarding our failure to obtain certain municipal licenses. We do not believe that we are subject to the license requirements at issue, and we have initiated proceedings to challenge the municipality’s claims. In Tijuana, the municipal government adopted certain environmental regulations, which could materially affect our operation of the airport. We initiated proceedings to challenge the authority of the municipal government to adopt such regulations. In response to our challenge the municipal government voluntarily abandoned its regulations. Judicial proceedings will remain pending until the court determines that there is no longer a matter in controversy.

Changes to the Mexican Customs Law

On January 1, 2002, the Mexican government amended the Mexican Customs Law (Ley de Aduanas), requiring Mexican airport operators, at their cost, to provide adequate facilities to customs authorities as well as to acquire, install and maintain equipment to be used by these authorities. Such equipment includes X-ray, gamma or other similar machinery to inspect cargo, weighing equipment, closed circuit cameras, and other items required to maintain the continuous operation of the customs computer system (including electricity, security and telecommunications equipment). Each of our airports filed anamparo (a legal proceeding similar to an injunction or a habeas corpus action) against the Mexican government challenging the legal validity of the amendment to the Mexican Customs Law and the applicable court ruled

132

in our favor in each case. On December 30, 2002, the Mexican government further amended the Mexican Customs Law, providing for certain additional requirements with respect to security equipment to be maintained at all Mexican airports. We have been advised by our Mexican counsel that the judgments with respect to theamparos filed by each of our airports in 2002 should apply to this additional amendment to the customs law; however, there can be no assurance that the Mexican government will agree with our analysis. If the Mexican government were to require us to comply, or, should the outcome of theamparos be adverse to us, we would be required to make the necessary expenditures. If we were required to make these expenditures, we do not believe that they would be material.

Claim against our Guadalajara airport subsidiary

In August 2005, we entered into a construction contract with Grupo de Ingeniería Universal, S.A. de C.V., or GIUSA, for the development of a new segment of the Guadalajara International Airport’s apron. GIUSA delayed the project and we therefore executed the performance bond posted by GIUSA in an amount equal to 20% of the total contract value. However, we were not able to obtain such execution because, in September 2006, GIUSA initiated legal proceedings against us, claiming breach of contract by us and seeking the full contract amount and additional damages, together totaling an approximate amount of Ps. 43 million. During 2007, we obtained a favorable sentence in first instance, which was appealed by GIUSA. The resolution of this proceeding is still pending.

DIVIDENDS

The declaration, amount and payment of dividends are determined by a majority vote of our stockholders present at a stockholders’ meeting and generally, but not necessarily, on the recommendation of the board of directors, which is empowered by Article 18 of our bylaws to set our dividend policies. So long as the Series BB shares represent at least 7.65% of our outstanding capital stock, the declaration and payment of dividends will require the approval of the holders of a majority of the Series BB shares.

Mexican law requires that at least 5% of a company’s net income each year (after profit sharing and other deductions required by Mexican law) be allocated to a legal reserve fund until such fund reaches an amount equal to at least 20% of the company’s capital stock from time to time (without adjustment for inflation). Our legal reserve fund was Ps. 225.1 million at December 31, 2007 (excluding reserve amounts corresponding to 2007 net income).

Mexican companies may pay dividends only out of earnings (including retained earnings after all losses have been absorbed or paid up) and only after such allocation to the legal reserve fund. The reserve fund is required to be funded on a stand-alone basis for each company, rather than on a consolidated basis. The level of earnings available for the payment of dividends is determined under MFRS. Our subsidiaries are required to allocate earnings to their respective legal reserve funds prior to paying dividends to Grupo Aeroportuario del Pacífico, S.A.B. de C.V. We are also required to allocate earnings to our legal reserve fund prior to distributing any dividend payments to our stockholders.

133

Dividends paid to non-resident holders with respect to our Series B shares and ADSs are currently not subject to Mexican withholding tax. Dividends that are paid from a company’s distributable earnings that have not been subject to corporate income tax will be subject to a corporate-level dividend tax (retained against cumulative net income and payable by us) calculated on a gross-up basis by applying a factor of 1.4286 in 2005, 1.4085 in 2006, and 1.3889 thereafter. Corporate tax rates of 30% in 2005, 29% in 2006 and 28% thereafter are applied to the result. This corporate-level dividend income tax on the distribution of earnings may be applied as a credit against Mexican corporate income tax corresponding to the fiscal year in which the dividend was paid or against the Mexican corporate income tax of the two fiscal years following the date in which the dividend was paid

Distributions made by us to our stockholders other than as dividends (in the manner described above), including capital reductions, amortization of shares or otherwise, would be subject to taxation in Mexico, including withholding taxes. The tax rates applicable and the method of assessing and paying taxes applicable to any such non-dividend distributions will vary depending on the nature of the distributions.

We paid aggregate dividends of Ps. 1,136.0 million in 2005, Ps. 774.3 million in 2006 and Ps. 1,171.6 million in 2007.

At the General Ordinary Shareholders’ Meeting held on April 28, 2008, we declared a dividend of Ps. 1,122 million that will be paid in two installments on May 12, 2008 and on October 31, 2008, at an amount of Ps. 2.00 per common share.

Our stockholders adopted a new dividend policy at the general extraordinary stockholders meeting held on April 15, 2005. Under the policy our annual dividend is expected to consist of two components. The first component is a fixed amount, which was Ps. 450 million for 2005 (for the dividend paid in 2006) and is intended to increase gradually in future years. Second, the dividend policy contemplates that our annual dividend will include any cash and cash equivalents we hold (as reflected in our balance sheet as of the month-end prior to the dividend payment, after deducting the fixed component) in excess of our ���minimum cash balance.” For purposes of our policy, the “minimum cash balance” is the amount of cash and cash equivalents that our board of directors determines is necessary to cover the minimum amount of expenses and investments expected to be incurred in the fiscal year during which the dividend payment is made and the subsequent fiscal year. Dividends are expected to be made payable in cash and in one or more payments as determined in the relevant general ordinary stockholders meeting approving dividends.

The declaration, amount and payment of dividends pursuant to the policy described above are subject to (i) compliance with applicable law regarding the declaration and payment of dividends with respect to any year including the establishment of the statutory legal reserve fund, and (ii) the absence of any adverse effect on our business plan for the current or subsequent fiscal year as a result of the payment of any dividend. We cannot assure you that we will continue to pay dividends or that future dividends will be comparable to our previous dividends. Our ability to pay dividends may be restricted under an unsecured peso-denominated credit agreement with Banamex, to which some of our operating subsidiaries are parties. See “Item 5, Operating and Financial Review and Prospects—Liquidity and Capital Resources.” Our dividend policy may also be amended at any time by our stockholders.

134

As of December 31, 2007, we had accumulated approximately Ps. 982.0 million of distributable earnings that had been subject to the corporate income tax and that could be declared at the relevant stockholders’ meeting and paid to stockholders free of the corporate level dividend tax.

We pay dividends in pesos. In the case of Series B shares represented by ADSs, the cash dividends are paid to the depositary and, subject to the terms of the Deposit Agreement, converted into and paid in U.S. dollars at the prevailing rate of exchange, net of conversion expenses of the depositary and applicable Mexican withholding tax. Fluctuations in exchange rates will affect the amount of dividends that ADS holders receive.

TRADING ON THE MEXICAN STOCK EXCHANGE

The Mexican Stock Exchange, located in Mexico City, is the only stock exchange in Mexico. Operating continuously since 1907, the Mexican Stock Exchange is organized as a corporation (sociedad anónima de capital variable). Securities trading on the Mexican Stock Exchange occurs each business day from 8:30 a.m. to 3:00 p.m., Mexico City time.

135

Since January 1999, all trading on the Mexican Stock Exchange has been effected electronically. The Mexican Stock Exchange may impose a number of measures to promote orderly and transparent trading in securities, including the operation of a system of automatic suspension of trading in shares of a particular issuer when price fluctuation exceeds certain limits. The Mexican Stock Exchange may also suspend trading in shares of a particular issuer as a result of:

• non-disclosure of material events; or

• changes in the offer or demand, volume traded, or prevailing share price that are inconsistent with the shares’ historical performance and cannot be explained through publicly available information.

The Mexican Stock Exchange may reinstate trading in suspended shares when it deems that the material events have been adequately disclosed to public investors or when it deems that the issuer has adequately explained the reasons for the changes in offer and demand, volume traded, or prevailing share price. Under current regulations, the Mexican Stock Exchange may consider the measures adopted by the other stock exchanges in order to suspend and/or resume trading in an issuer’s shares in cases where the relevant securities are simultaneously traded on a stock exchange outside of Mexico.

Settlement on the Mexican Stock Exchange is effected three business days after a share transaction. Deferred settlement is not permitted without the approval of the Mexican National Banking and Securities Commission, even where mutually agreed. Most securities traded on the Mexican Stock Exchange are on deposit with theS.D. Indeval, S.A. de C.V. Institución para el Depósito de Valores, or INDEVAL, a privately owned securities depositary that acts as a clearinghouse, depositary, and custodian, as well as a settlement, transfer, and registration agent for Mexican Stock Exchange transactions, eliminating the need for physical transfer of securities.

Although the Securities Market Law provides for the existence of an over-the-counter market, no such market for securities in Mexico has developed.

The market value of securities of Mexican companies is, to varying degrees, affected by economic and market conditions in other emerging market countries and in the United States. In late October 1997, for example, prices of both Mexican debt securities and Mexican equity securities dropped substantially following declines earlier in the year in the Asian and Brazilian securities markets.

On December 30, 2005, a new Securities Market Law was enacted and published in the Mexican Federal Gazette. The new Securities Market Law became effective on June 28, 2006; however, in some cases an additional period of 180 days (until late December 2006) was made available for issuers (including us) to incorporate the new corporate governance and other requirements derived from the new law into their bylaws. The new Securities Market Law changed Mexican securities regulation in various material respects. The reforms were intended to update the Mexican regulatory framework applicable to the securities market and publicly traded companies in accordance with international standards.

136

In particular, the new Securities Market Law (i) establishes that public entities and the entities controlled by them will be considered a single economic unit (e.g., holding companies and wholly owned subsidiaries), (ii) clarifies the rules for tender offers, dividing them into voluntary and mandatory categories, (iii) clarifies standards for disclosure of holdings of stockholders of public companies, (iv) clarifies the role of the board of directors of public companies and redistributes responsibilities between the board of directors and the chief executive officer, (v) defines the standards applicable to the board of directors and the duties of the board, each director, its secretary, the general director and executive officers (introducing concepts such as the duty of care, duty of loyalty and safe harbors), (vi) replaces the statutory auditor (comisario) and its duties with an audit committee, corporate governance requirements and external auditors, (vii) defines the roles and responsibilities of executive officers, (viii) improves the rights of minority stockholders relating to legal remedies and access to company information, (ix) introduces concepts such as consortiums, groups of related persons or entities, control, related parties and decision-making power, and (x) expands the definition of applicable sanctions for violations of the Securities Market Law, including damages, fines and criminal penalties.

Item 10. Additional Information

CORPORATE GOVERNANCE

Bylaws

This section summarizes certain provisions of Mexican law and ourestatutos sociales(bylaws).

At our extraordinary stockholders’ meeting held on October 27, 2006, our stockholders adopted resolutions amending and restating of our bylaws to organize the company as asociedad anónima bursátil(a form newly required by law for publicly traded companies in Mexico), and conform our bylaws to the provisions of the new Securities Market Law. Many of the changes related to the enhancement of our corporate governance.

Board of Directors

Our bylaws provide that our board of directors will generally have 11 members (increasing to 12 or 13 members only when necessary to preserve minority stockholders’ voting rights in cases of multiple appointments by persons with 10% interests (as described below)).

At each stockholders’ meeting for the election of directors, the holders of Series BB shares are entitled to elect four directors. The remaining members of the board of directors are to be elected by the holders of the Series B shares.

Each person (or group of persons acting together) holding 10% of our capital stock in the form of Series B shares is entitled to appoint one director. The remaining positions on the board of directors will be filled based on the vote of all holders of Series B shares that have not elected

137

to appoint a director by virtue of owning 10% of our capital stock. The candidates to be considered for election as directors by the Series B stockholders are proposed to the stockholders by the Nominations and Compensation Committee. All directors are elected based on a simple majority of the votes cast at the relevant stockholders’ meeting. Our bylaws do not currently require mandatory retirement of directors after they reach a certain age. The compensation of our directors is proposed by the Nominations and Compensation Committee to all of our stockholders at stockholders’ meetings for their approval.

Pursuant to the Securities Market Law, 25% of our directors must be independent within the definition of that term specified therein.

Authority of the Board of Directors

The board of directors is our legal representative. The powers of the board include, among others, the following:

• to define our strategic planning decisions and approve our annual business plans and investment budgets,

• to approve our master development programs and modifications thereto,

• to call stockholders’ meetings and act upon stockholders’ resolutions, and

• to create special committees and grant them the powers and authority as it sees fit, provided that said committees will not be vested with the authorities which by law or under our bylaws are expressly reserved for the stockholders or the board of directors.

Meetings of the board of directors will be validly convened and held if a majority of the members are present. Resolutions at said meetings will be valid if approved by a majority of the members of the board of directors, unless our bylaws require a higher number. Notwithstanding the board’s authority, under general principles of Mexican law, our stockholders, pursuant to a decision validly taken at a stockholders’ meeting, may at any time override the board.

Powers of Series BB Directors

The Series BB directors are entitled to: (i) appoint and remove our chief executive officer and our other top-level executive officers (upon consultation with our Nominations and Compensation Committee); (ii) appoint three members of the Operating Committee and their respective alternates; (iii) appoint 20% of the total members of the Audit Committee, the Acquisitions Committee and the Nominations and Compensation Committee (a minimum of one member per committee), and their respective alternatives; and (iv) consent to the appointment of individuals appointed to the Operating Committee who are not members of our board of directors or our officers.

In addition to the foregoing, each of the following actions of our board of directors, among certain others, may only occur with the approval of the Series BB directors:

• approval of our airports’ five-five year master development programs or amendments thereto;

138

• approval of our annual business and investment plans;

• approval of capital expenditures outside of our annual investment plans;

• approval of any sale of our fixed assets, individually or jointly, in an amount exceeding U.S$3.0 million;

• approval for us to enter into any type of loan or credit agreement, other than for certain loans granted by us to our subsidiaries;

• approval of the granting by us of guarantees (avales) or other security interests other than for the benefit of our subsidiaries;

• proposing to increase our capital stock or that of our subsidiaries;

• approval of sales of shares in our subsidiaries;

• approval of our dividend policies; and

• proposing individuals to join our Audit Committee or our Nominations and Compensation Committee.

Our Capital Stock

The following table sets forth our authorized capital stock and our issued and outstanding capital stock as of December 31, 2007:

Capital Stock

	Authorized	Issued and outstanding
Capital stock:
Series B shares	476,850,000	476,850,000
Series BB shares	84,150,000	84,150,000

All ordinary shares confer equal rights and obligations to holders within each series. The Series BB shares have the voting and other rights described below.

Our bylaws provide that our shares have the following characteristics:

• Series B.Series B shares currently represent 85% of our capital, and may represent up to 100% of our share capital. Series B shares may be held by any Mexican or foreign natural person, company or entity, except for foreign governments.

139

• Series BB.Series BB shares currently represent 15% of our capital and may not represent a greater percentage of our share capital. Like Series B shares, Series BB shares may be held by any Mexican or foreign natural person, company or entity, except for foreign governments and subject to the other requirements of our bylaws.

(Under the Mexican Airport Law and the Mexican Foreign Investments Law (Ley de Inversión Extranjera), foreign persons may not directly or indirectly own more than 49% of the capital stock of a holder of an airport concession unless an authorization from the Mexican Commission of Foreign Investments is obtained. We have obtained this authorization and as a consequence these restrictions do not apply to our Series B or Series BB shares.)

Series BB shares are subject to transfer restrictions under our bylaws and generally must be converted to Series B shares before they can be transferred. Up to 49% of the Series BB shares can be converted into Series B shares at any time. The remaining 51% of Series BB shares cannot be converted into Series B shares before August 25, 2009 absent prior approval by the Ministry of Communications and Transportation. Thereafter and until August 25, 2014, one fifth of such 51% may be converted each year. On or after August 25, 2014, all of the Series BB shares may be converted into Series B shares if (i) the technical assistance agreement between AMP and us has not been renewed and (ii) the Series BB stockholders so request. Notwithstanding the foregoing, if at any time after August 25, 2014, Series BB shares represent less than 7.65% of our share capital, those shares will be mandatorily converted into Series B shares and the Technical Assistance Agreement will be terminated.

Voting Rights and Stockholders’ Meetings

Each Series B share and Series BB share entitles the holder to one vote at any general meeting of our stockholders. Holders of Series BB shares are entitled to elect four members of our board of directors and holders of Series B shares are entitled to elect the remaining members of the board of directors.

Under Mexican law and our bylaws, we may hold three types of stockholders’ meetings: ordinary, extraordinary, and special. Ordinary stockholders’ meetings are those called to discuss any issue not reserved for extraordinary stockholders’ meeting. An annual ordinary stockholders’ meeting (our annual general meeting) must be convened and held within the first four months following the end of each fiscal year to discuss, among other things, the report prepared by the board on our financial statements, the appointment of members of the board of directors, the declaration of dividends and the determination of compensation for members of the board.

Extraordinary stockholders’ meetings are those called to consider any of the following matters:

• the extension of our duration or our voluntary dissolution;

• an increase or decrease in our minimum fixed capital;

• a change in corporate purpose or nationality;

140

• any transformation, merger or spin-off involving the company;

• any stock redemption or issuance of preferred stock or bonds;

• the cancellation of the listing of our shares with the National Securities Registry or on any stock exchange;

• amendments to our company’s bylaws; and

• any other matters for which applicable Mexican law or the bylaws specifically require an extraordinary meeting.

Special stockholders’ meetings are those called and held by stockholders of the same series or class to consider any matter particularly affecting the relevant series or class of shares.

Stockholders’ meetings are required to be held in our corporate domicile, which is Mexico City. Calls for stockholders’ meetings must be made by the board of directors or the audit committee. Any stockholder or group of stockholders representing at least 10% of our capital stock has the right to request that the board of directors or the audit committee call a stockholders’ meeting to discuss the matters indicated in the relevant request. In certain circumstances specified in Mexican law, any individual stockholder may also make such a request. If the board of directors or the audit committee fails to call a meeting within 15 calendar days following receipt of the request, the stockholder or group of stockholders may request that the call be made by a competent court.

Calls for stockholders’ meetings must be published in the Mexican Federal Gazette or in one newspaper of general circulation in Mexico at least 15 calendar days prior to the date of the meeting. Each call must set forth the place, date and time of the meeting and the matters to be addressed. Stockholders’ meetings will be validly held and convened without the need for a prior call or publication whenever all the shares representing our capital are duly represented.

To be admitted to any stockholders’ meeting, stockholders must be registered in our share registry and comply with the requirements set forth in our bylaws. Stockholders may be represented at any stockholders’ meeting by one or more attorneys-in-fact who may not be our directors.

At or prior to the time of the publication of any call for a stockholders’ meeting, we will provide copies of the publication to the depositary for distribution to the holders of ADSs. Holders of ADSs are entitled to instruct the depositary as to the exercise of voting rights pertaining to the Series B shares.

Quorums

Ordinary meetings are regarded as legally convened pursuant to a first call when more than 50% of the shares representing our capital are present or duly represented. Resolutions at ordinary meetings of stockholders are valid when approved by a majority of the shares present or duly represented at the meeting. Any number of shares represented at an ordinary meeting of stockholders convened pursuant to a second or subsequent call constitutes a quorum. Resolutions at ordinary meetings of stockholders convened in this manner are valid when approved by a majority of the shares represented at the meeting.

141

Extraordinary and special stockholders’ meetings are regarded as legally convened pursuant to a first or subsequent call when at least 75% of the shares representing our capital (or 75% of the relevant series) are present or duly represented. Resolutions at extraordinary meetings of stockholders are valid if taken by the favorable vote of shares representing more that 50% of our capital (or 50% of the relevant series).

Notwithstanding the foregoing, resolutions at extraordinary meetings of stockholders called to discuss any of the issues listed below are valid only if approved by a vote of shares representing at least 75% of our capital:

• any amendment to our bylaws which: (i) changes or deletes the authorities of our committees; or (ii) changes or deletes the rights of minority stockholders,

• any actions resulting in the cancellation of the concessions granted to us or our subsidiaries by the Mexican government or any assignment of rights arising therefrom,

• termination of the participation agreement between us and AMP,

• a merger by us with an entity the business of which is not directly related to the business of us or our subsidiaries, or

• a spin-off, dissolution or liquidation of us.

Our bylaws also establish the following voting requirements:

• the amendment of the restrictions in our bylaws on ownership of shares of our capital stock requires the vote of holders of 85% of our capital stock,

• a delisting of our shares requires the vote of holders of 95% of our capital stock, and

• the amendment of the provisions in our bylaws requiring that a stockholder exceeding our share ownership limits conduct a public sale of his excess shares requires the vote of holders of 85% of our capital stock.

Veto Rights of Holders of Series BB Shares

So long as the Series BB shares represent at least 7.65% of our capital stock, resolutions adopted at stockholders’ meetings with respect to any of the issues listed below will only be valid if approved by a vote of a majority of the Series BB shares:

• approval of our financial statements;

• liquidation or dissolution;

• capital increases or decreases;

142

• declaration and payment of dividends;

• amendment to our bylaws;

• mergers, spin-offs or share-splits;

• grant or amendment of special rights to any series of shares; and

• any decision amending or nullifying a resolution validly taken by the board of directors with respect to (i) appointment of our top-level executive officers, (ii) appointment of the three members of our Operating Committee and of the members of the Audit, Acquisitions and Nominations and Compensation committees to be designated by the directors elected by the holders of the Series BB shares, and (iii) appointment of the members of the Operating Committee whose appointment requires the consent of the directors elected by the holders of the Series BB shares, and decisions of the board of directors that require the affirmative vote of the directors elected by the holders of our Series BB shares.

Dividends and Distributions

At our annual ordinary general stockholders’ meeting, the board of directors will submit to the stockholders for their approval our audited consolidated financial statements for the preceding fiscal year. Five percent of our net income (after profit sharing and other deductions required by Mexican law) must be allocated to a legal reserve fund until the legal reserve fund reaches an amount equal to at least 20% of our capital stock (without adjustment for inflation). Additional amounts may be allocated to other reserve funds as the stockholders may from time to time determine including a reserve to repurchase shares. The remaining balance, if any, of net earnings may be distributed as dividends on the shares of common stock. A full discussion of our dividend policy may be found in “Item 8, Financial Information—Dividends.” On May 18, 2007, we made a dividend payment of Ps. 837.6 million and on October 31, 2007, we made a dividend payment of Ps. 334.0 million.

Registration

Our shares have been registered with the National Securities Registry, as required under the Securities Market Law and regulations issued by the Mexican National Banking and Securities Commission. If we wish to cancel our registration, or if it is cancelled by the Mexican National Banking and Securities Commission, we will be required to make a public offer to purchase all outstanding shares, prior to such cancellation. Unless the Mexican National Banking and Securities Commission authorizes otherwise, the price of the offer to purchase will be the higher of: (i) the average of the trading price of our shares during the prior thirty trading days (during a period of no more than six months); or (ii) the book value of the shares in accordance with the most recent quarterly report submitted to the Mexican National Banking and Securities Commission and to the Mexican Stock Exchange. Any waiver to the foregoing provisions included in our bylaws requires the prior approval of the Mexican National Banking and Securities Commission and the approval, at an extraordinary stockholders’ meeting, of 95% of our outstanding capital stock.

143

Stockholder Ownership Restrictions and Antitakeover Protection

Holders of our shares are subject to the following restrictions:

• holders of Series B shares, either individually or together with their related persons, may not directly or indirectly own more than 10% of our Series B shares,

• Although there is no limit on individual holdings of Series BB shares, Series BB shares may represent no more than 15% of our outstanding capital stock,

• holders of Series BB shares may also own Series B shares, and

• no stockholder may vote more than 10% of our capital stock. Shares in excess of this threshold will be voted in the same manner as the majority of our shares.

• foreign governments acting in a sovereign capacity may not directly or indirectly own any portion of our capital stock.

A person exceeding the 10% threshold described above with respect to our Series B shares must conduct a public offer of his excess shares.

Any amendment to the ownership restrictions described above requires the vote of shares representing 85% of our capital stock.

Changes in Capital Stock

Increases and reductions of our minimum fixed capital must be approved at an extraordinary stockholders’ meeting, subject to the provisions of our bylaws and the Mexican General Law of Business Corporations. Increases or reductions of the variable capital must be approved at an ordinary stockholders’ meeting in compliance with the voting requirements of our bylaws.

Pursuant to Article 53 of the Securities Market Law, we may issue unsubscribed shares that will be kept in treasury, to be subsequently subscribed by the investing public, provided that

• the general extraordinary stockholders’ meeting approves the maximum amount of the capital increase and the conditions upon which the corresponding placement of shares shall be made,

• the subscription of issued shares is made through a public offer following registration in the National Securities Registry and complying with the provisions of the Securities Market Law and other applicable law, and

• the amount of the subscribed and paid-in capital of the company is announced when the company makes the authorized capital increase public.

144

The preferential subscription right provided under Article 132 of the General Law of Business Entities (Ley General de Sociedades Mercantiles) is not applicable to capital increases through public offers.

Subject to the individual ownership limitations set forth in our bylaws, in the event of an increase of our capital stock our stockholders will have a preemptive right to subscribe and pay for new stock issued as a result of such increase in proportion to their stockholder interest at that time, unless: the capital increase is made under the provisions of Article 53 of the Securities Market Law. Said preemptive right shall be exercised by any method provided in Section 132 of the Mexican General Corporations Law, by subscription and payment of the relevant stock within fifteen business days after the date of publication of the corresponding notice to our stockholders in the Mexican Federal Gazette and in one of the newspapers of greater circulation in Mexico, provided that if at the corresponding meeting all of our shares are duly represented, the fifteen business day period shall commence on the date of the meeting.

Our capital stock may be reduced by resolution of a stockholders’ meeting taken generally pursuant to the rules applicable to capital increases. Our capital stock may also be reduced upon repurchase of our own stock in accordance with the Securities Market Law (See “—Share Repurchases” below).

Share Repurchases

We may choose to acquire our own shares or negotiable instruments representing such shares through the Mexican Stock Exchange on the following terms and conditions:

• The acquisition and sale on the Mexican Stock Exchange is made at market price (except when dealing with public offerings or auctions authorized by the National Banking and Securities Commission).

• If the acquisition is charged against working capital, the shares may be kept by us without need to make a reduction in our capital stock. Otherwise, if the acquisition is charged against our capital stock, the shares will be converted into unsubscribed shares kept in our treasury, without need for a resolution by our stockholders’ at a stockholders’ meeting.

• The company must announce the amount of the subscribed and paid-in capital when the amount of the authorized capital represented by the issued and unsubscribed shares is publicly announced.

• The general ordinary stockholders’ meeting will expressly determine for each fiscal year the maximum amount of resources that we may use to purchase our own shares or negotiable instruments that represent such shares, with the only limitation that the sum or total of the resources that may be used for such purpose may not exceed, at any time, the total balance of the net profits of the company, including retained profits.

• We must be up to date in the payment of obligations under debt instruments issued and registered in the National Securities Registry that we may have issued.

145

Shares of the company belonging to us may not be represented or voted in stockholders’ meetings, nor may corporate or economic rights of any kind be exercised, nor will the shares be considered as outstanding for the purpose of determining the quorum or voting in stockholders’ meetings.

In the General Ordinary Shareholders’ Meeting held on April 28, 2008, a stock buy-back program was approved under the Mexican Law rules, for a maximum amount of Ps. 5 million for the period from April 28, 2008 to April 27, 2009.

Ownership of Capital Stock by Subsidiaries

Our subsidiaries may not, directly or indirectly, invest in our shares, except for shares of our capital stock acquired as part of any employee stock option plan, which may not exceed 25% of our capital stock, or through asset managers (sociedades de inversión).

Liquidation

Upon our dissolution, one or more liquidators must be appointed at an extraordinary stockholders’ meeting to wind up our affairs. All fully paid and outstanding shares will be entitled to participate equally in any distribution upon liquidation. Partially paid shares participate in any distribution in the same proportion that such shares have been paid at the time of the distribution.

Other Provisions

Liabilities of the members of the Board of Directors

As in any other Mexican corporation, and due to the provisions contained in Article 38 of the Securities Market Law, any stockholder or group of stockholders holding at least 5% of our capital stock may directly exercise a civil liability action under Mexican law against the members of the board of directors.

In addition to the foregoing, our bylaws provide that, a member of the board of directors will be liable to us and our stockholders for breaching his or her duties, as provided under articles 29 to 37 of the Securities Market Law.

Our by-laws provide that the members of the board of directors, or the board committees, and the secretary shall be indemnified by us in case of violations of their duty of care (deber de diligencia), as long as they did not act in bad faith, violate their duty of loyalty or committed an illicit act under the Securities Market Law or other applicable law. Additionally, our bylaws provide that we shall indemnify the members of the board of directors and the secretary for any indemnification liability which they may incur as long as they have not acted in bad faith, violated their duty of loyalty or committed an illicit act under the Securities Market Law or other applicable law.

146

Information to Stockholders

The Securities Market Law establishes that we, acting through our boards of directors, must annually present a report at a stockholder’s meeting that includes the following:

• A report prepared by the chairman of our Audit Committee, as required by Article 43 of the Securities Market Law, which must cover, among other things: (i) the performance of our top-level officers, (ii) transactions with related persons, (iii) the compensation packages for our directors and officers, (iv) waivers granted by the board of directors regarding corporate opportunities, (v) the situation of our, and our subsidiaries’ internal controls and internal auditing, (vi) preventive and corrective measures adopted in connection with non-compliance with operational and accounting guidelines, (vii) the performance of our external auditor, (viii) additional services provided by our external auditor and independent experts, (ix) the main results of the review of our, and our subsidiaries’, financial statements, and (x) the effects of changes to our accounting policies.

• The report prepared by the chief executive officer under article 44, paragraph XI of the Securities Market Law. This report must be accompanied by the report (dictamen) of the external auditor, and should include, among other things: (i) a report of the directors on the operations of the company during the preceding year, as well as on the policies followed by the directors and on the principal existing projects of the company, (ii) a statement of the financial condition of the company at the end of the fiscal year, (iii) a statement regarding the results of operations of the company during the preceding year, as well as changes in the company’s financial condition and capital stock during the preceding year, and (iv) the notes which are required to complete or clarify the foregoing information.

• The board’s opinion on the contents of the report prepared by the chief executive officer and mentioned in the preceding paragraph.

• A report explaining the principal accounting and information policies and criteria followed in the preparation of the financial information.

• A report regarding the operations and activities in which the board participated, as provided under the Securities Market Law.

In addition to the foregoing, our bylaws specify additional information obligations of the board of directors, including that the board of directors should also prepare the information referred to in Article 172 of the General Law on Business Entities with respect to any subsidiary that represents at least 20% of our net worth (based on the financial statements most recently available).

Duration

The duration of our corporate existence has been set at 100 years, ending in the year 2098.

147

Stockholders’ Conflict of Interest

Under Mexican law, any stockholder that has a conflict of interest with respect to any transaction must abstain from voting thereon at the relevant stockholders’ meeting. A stockholder that votes on a transaction in which its interest conflicts with ours may be liable for damages in the event the relevant transaction would not have been approved without such stockholder’s vote.

Directors’ Conflict of Interest

Under Mexican law, any director who has a conflict of interest in any transaction must disclose such fact to the other directors and abstain from voting on such transaction. Any director who violates such provision will be liable to us for any resulting damages or losses. Additionally, under our bylaws, certain conflicts of interest will have the effect of disqualifying a person from serving on our board of directors.

MATERIAL CONTRACTS

Our subsidiaries are parties to the airport concessions granted by the Ministry of Communications and Transportation under which we are required to construct, operate, maintain and develop the airports in exchange for certain benefits. See “—Sources of Regulation” and “—Scope of Concessions and General Obligations of Concession Holders” under “Regulatory Framework” in Item 4.

We are a party to a participation agreement with AMP and the Ministry of Communications and Transportation which establishes the framework for several other agreements to which we are a party. See “Item 7, Major Stockholders and Related Party Transactions—Related Party Transactions.”

We have entered into a technical assistance agreement with AMP providing for management and consulting services. See “Item 7, Major Stockholders and Related Party Transactions—Related Party Transactions.”

EXCHANGE CONTROLS

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

TAXATION

The following summary contains a description of the material U.S. and Mexican federal income tax consequences of the purchase, ownership and disposition of our Series B shares or ADSs by a beneficial holder that is a citizen or resident of the United States or a U.S. domestic corporation or that otherwise is subject to U.S. federal income tax on a net income basis in respect of our Series B shares or ADSs and that is a “non-Mexican holder” (as defined below) (a

148

“U.S. holder”), but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a decision to purchase, hold or dispose of our Series B shares or ADSs. In particular, the summary deals only with U.S. holders that hold our Series B shares or ADSs as capital assets and does not address the tax treatment of special classes of U.S. holders such as dealers in securities or currencies, U.S. holders whose functional currency is not the U.S. dollar, U.S. holders that own or are treated as owning 10% or more of our outstanding voting shares, tax-exempt organizations, financial institutions, U.S. holders liable for the alternative minimum tax, securities traders who elect to account for their investment in Series B shares or ADSs on a mark-to-market basis and persons holding Series B shares or ADSs in a hedging transaction or as part of a straddle, conversion or other integrated transaction for U.S. federal income tax purposes. In addition, the summary does not address any U.S. or Mexican state or local tax considerations that may be relevant to a U.S. holder.

The summary is based upon the federal income tax laws of the United States and Mexico as in effect on the date of this Form 20-F, including the provisions of the income tax treaty between the United States and Mexico and protocol thereto (the “Tax Treaty”), all of which are subject to change, possibly with retroactive effect in the case of U.S. federal income tax law. Prospective investors in our Series B shares or ADSs should consult their own tax advisors as to the US, Mexican or other tax consequences of the purchase, ownership and disposition of the Series B shares or ADSs, including, in particular, the effect of any foreign, state or local tax laws and their entitlement to the benefits, if any, afforded by the Tax Treaty.

For purposes of this summary, the term “non-Mexican holder” shall mean a holder that is not a resident of Mexico and that does not hold the Series B shares or ADSs or a beneficial interest therein in connection with the conduct of a trade or business through a permanent establishment or fixed base in Mexico.

For purposes of Mexican taxation, the definition of residency is highly technical and residency results in several situations. Generally an individual is a resident of Mexico if he or she has established his or her home in Mexico, and a corporation is a resident if it is incorporated under Mexican law or it has its center of interests in Mexico. An individual who has a home in Mexico and another country will be considered to be a resident of Mexico if Mexico is the individual’s significant center of interest. An individual’s significant center of interest will be considered Mexico in the following circumstances, among others: (i) when more than 50% of such person’s total yearly income originates in Mexico, and (ii) when Mexico is the individual’s principal place of business. Additionally, Mexican officers and employees working for the Mexican government but living outside of Mexico will be considered to be Mexican residents even if their significant center of interest is not in Mexico. However, any determination of residence should take into account the particular situation or each person or legal entity.

In general, for U.S. federal income tax purposes, holders of ADSs are treated as the beneficial owners of the Series B shares represented by those ADSs.

149

Taxation of Dividends

Mexican Tax Considerations

Under Mexican Income Tax Law provisions, dividends paid to non-Mexican holders with respect to our Series B shares or ADSs are not subject to any Mexican withholding tax.

U.S. Federal Income Tax Considerations

The gross amount of any distributions paid with respect to the Series B shares or ADSs, to the extent paid out of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes, generally are includible in the gross income of a U.S. holder as ordinary income on the date on which the distributions are received by the depositary and are not eligible for the dividends received deduction allowed to certain corporations under the U.S. Internal Revenue Code of 1986, as amended. To the extent that a distribution exceeds our current and accumulated earnings and profits, it is treated as a non-taxable return of basis to the extent thereof, and thereafter as capital gain from the sale of Series B shares or ADSs. Distributions, which are made in pesos, are includible in the income of a U.S. holder in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date they are received by the depositary whether or not they are converted into U.S. dollars. If such distributions are converted into U.S. dollars on the date of receipt, a U.S. holder generally should not be required to recognize foreign currency gain or loss in respect of the distributions.

Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by an individual U.S. holder prior to January 1, 2011 with respect to the ADSs will be subject to taxation at a maximum rate of 15% if the dividends are “qualified dividends.” Dividends paid on the ADSs will be treated as qualified dividends if: (i) the ADSs are readily tradable on an established securities market in the United States, and (ii) the issuer was not, in the year prior to the year in which the dividend was paid, and is not, in the years in which the dividend is paid, a passive foreign investment company (PFIC). The ADSs are listed on the New York Stock Exchange, and will qualify as readily tradable on an established securities market in the United States so long as they are so listed. Based on our audited consolidated financial statements and relevant market and stockholder data, we believe that we were not treated as a PFIC for U.S. federal income tax purposes with respect to our 2007 taxable year. In addition, based on our audited consolidated financial statements and our current expectations regarding the value and nature of our assets, the sources and nature of our income, and relevant market and stockholder data, we do not anticipate becoming a PFIC for our 2008 taxable year.

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

150

Taxation of Dispositions of Shares or ADSs

Mexican Tax Considerations

Gain on the sale or other disposition of ADSs by a non-Mexican holder are not subject to any Mexican tax. Deposits and withdrawals of our Series B shares in exchange for ADSs do not give rise to Mexican tax or transfer duties.

Gain on the sale of our Series B shares by a non-Mexican holder is not subject to any Mexican tax if the transaction is carried out through the Mexican Stock Exchange or other securities markets approved by the Mexican Treasury Department, and provided certain requirements set forth by the Mexican Income Tax Law (Ley del Impuesto sobre la Renta) are complied with. Sales or other dispositions of Series B shares made in other circumstances generally are subject to Mexican tax, except to the extent that a holder is eligible for benefits under an income tax treaty to which Mexico is a party. Under the Tax Treaty, a holder that is eligible to claim the benefits of the Tax Treaty is exempt from Mexican tax on gains realized on a sale or other disposition of the Series B shares in a transaction that is not carried out through the Mexican Stock Exchange or such other approved securities markets, so long as the holder did not own, directly or indirectly, 25% or more of our capital stock (including ADSs) within the 12-month period preceding such sale or other disposition.

For non-Mexican holders that do not meet the requirements referred to above, gross income realized on the sale of the Series B shares is subject to a 5% Mexican withholding tax if the transaction is carried out through the Mexican Stock Exchange. Alternatively, a non-Mexican holder can choose to be subject to a 20% withholding rate on the net gain obtained, as calculated pursuant to Mexican Income Tax Law provisions.

U.S. Tax Considerations

Upon the sale or other disposition of the Series B shares or ADSs, a U.S. holder generally must recognize capital gain or loss in an amount equal to the difference between the amount realized on the sale or other disposition and such U.S. holder’s tax basis in the Series B shares or ADSs. Gain or loss recognized by a U.S. holder on such sale or other disposition generally is treated as long-term capital gain or loss if, at the time of the sale or other disposition, the Series B shares or ADSs had been held for more than one year. Long-term capital gain recognized by a U.S. holder that is an individual is subject to lower rates of federal income taxation than ordinary income or short-term capital gain. The deduction of a capital loss is subject to limitations for U.S. federal income tax purposes. Deposits and withdrawals of Series B shares by U.S. holders in exchange for ADSs will not result in the realization of gain or loss for U.S. federal income tax purposes.

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

151

Other Mexican Taxes

There are no Mexican inheritance, gift, succession or value added taxes applicable to the ownership, transfer or disposition of the Series B shares or ADSs by non-Mexican holders; provided, however, that gratuitous transfers of the Series B shares or ADSs may in certain circumstances cause a Mexican federal tax to be imposed upon the recipient. There are no Mexican stamp, issue, registration or similar taxes or duties payable by non-Mexican holders of the Series B shares or ADSs.

U.S. Backup Withholding Tax and Information Reporting Requirements

In general, information reporting requirements apply to payments by a paying agent within the United States to a non-corporate (or other non-exempt) U.S. holder of dividends in respect of the Series B shares or ADSs or the proceeds received on the sale or other disposition of the Series B shares or ADSs, and a backup withholding tax may apply to such amounts if the U.S. holder fails to provide an accurate taxpayer identification number to the paying agent. Amounts withheld as backup withholding tax are creditable against the U.S. holder’s U.S. federal income tax liability, provided that the required information is furnished to the U.S. Internal Revenue Service.

Item 11. Quantitative and Qualitative Disclosures About Market Risk

We are principally exposed to market risks from fluctuations in foreign currency exchange rates.

Our principal exchange rate risk involves changes in the value of the peso relative to the dollar. Historically, a significant portion of the revenues generated by our airports (principally derived from passenger charges for international passengers) has been denominated in or linked to the U.S. dollar, although such revenues are collected in pesos based on the average exchange rate for the prior month. In 2005, 2006 and 2007, approximately 32.5%, 31.5% and 27.8%, respectively, of our consolidated revenues were derived from passenger charges for international passengers. Substantially all of our other revenues are denominated in pesos. We estimate that substantially all of our consolidated costs and expenses are denominated in pesos (other than the salaries of our executive officers and the technical assistance fee, to the extent paid based on the fixed minimum annual payment). Based upon a 1% depreciation of the peso compared to the U.S. dollar as of December 31, 2007, we estimate that our revenues would have increased by Ps. 0.9 million.

152

As of December 31, 2005, 2006 and 2007, 22.8%, 12.3% and 14.7%, respectively, of our cash and marketable securities were denominated in dollars. Based upon a 1% depreciation of the peso compared to the U.S. dollar as of December 31, 2007, we estimate that the value of our cash and marketable securities would have increased by Ps. 0.2 million.

We did not have any foreign currency indebtedness at December 31, 2005, 2006 and 2007. In the event that we incur foreign currency denominated indebtedness in the future, decreases in the value of the peso relative to the dollar will increase the cost in pesos of servicing such indebtedness.

At December 31, 2005, 2006 and 2007 we did not have any outstanding forward foreign exchange contracts.

Item 15. Controls and Procedures

(a) Disclosure Controls and Procedures

We have evaluated, with the participation of our chief executive officer and chief financial officer, the effectiveness of our disclosure controls and procedures as of December 31, 2007. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

There was no change in our internal control over financial reporting during 2007 that materially affected, or would be reasonably likely to materially affect, our internal control over financial reporting.

(b) Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities and Exchange Act of 1934. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that:

(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;

154

(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

(3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate. Under the supervision of our Chief Executive Officer and Chief Financial Officer, our management assessed the design and effectiveness of our internal control over financial reporting as of December 31, 2007. In making its assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control — Integrated Framework.

Based on our assessment and those criteria, our management believes that our company maintained effective internal control over financial reporting as of December 31, 2007.

(c) Report of Independent Registered Public Accounting Firm on Internal Controls

Galaz, Yamazaki, Ruíz Urquiza, S.C. a member of Deloitte Touche Tohmatsu, the independent registered public accounting firm that has audited our financial statements, has issued an attestation report on our internal control over financial reporting. That report appears directly below.

We have audited the internal control over financial reporting of Grupo Aeroportuario del Pacífico, S.A.B. de C.V. and subsidiaries (the “Company”) as of December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

155

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2007 of the Company and our report dated June 16, 2008 expressed an unqualified opinion on those financial statements and includes explanatory paragraphs regarding (i) the nature and effect of differences between Mexican Financial Reporting Standards and accounting principles generally accepted in the United States of America and (ii) the translation of financial statements into English.

Report of Independent Registered Public Accounting Firm to the Board of Directors and Stockholders of Grupo Aeroportuario del Pacífico, S.A.B. de C.V.

We have audited the accompanying consolidated balance sheets of Grupo Aeroportuario del Pacífico, S.A.B. de C.V. and subsidiaries (the “Company”) as of December 31, 2007 and 2006, and the related consolidated statements of income, changes in stockholders’ equity and changes in financial position for each of the three years in the period ended December 31, 2007. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

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

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Grupo Aeroportuario del Pacífico, S.A.B. de C.V. and subsidiaries as of December 31, 2007 and 2006, and the results of their operations, changes in their stockholders’ equity and changes in their financial position for each of the three years in the period ended December 31, 2007, in conformity with Mexican Financial Reporting Standards.

Mexican Financial Reporting Standards vary in certain significant respects from accounting principles generally accepted in the United States of America. Information relating to the nature and effect of such differences is presented in Note 24 to the consolidated financial statements.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2007, based on the criteria established inInternal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated June 16, 2008 expressed an unqualified opinion on the Company’s internal control over financial reporting.

The accompanying consolidated financial statements have been translated into English solely for the convenience of readers.

Grupo Aeroportuario del Pacífico, S.A.B. de C.V. and Subsidiaries

Notes to Consolidated Financial Statements

For the years ended December 31, 2007, 2006 and 2005

(In thousands of Mexican Pesos of purchasing power of December 31, 2007, except share and per share data)

1. Activities and significant events

a. Activities

Grupo Aeroportuario del Pacífico, S.A.B. de C.V. and subsidiaries (the “Company” or “GAP”) was incorporated in May 1998 as a state-owned entity to manage, operate and develop 12 airport facilities, mainly in Mexico’s Pacific region. The airports are located in the following cities: Guadalajara, Puerto Vallarta, Tijuana, San José del Cabo, Silao (Bajío), Hermosillo, Mexicali, Los Mochis, La Paz, Manzanillo, Morelia and Aguascalientes.

The Company began operations on November 1, 1998. Prior to that date, the Company’s activities were carried out by Aeropuertos y Servicios Auxiliares (“ASA”), a Mexican Government agency, which was responsible for the operation of all public airports in Mexico.

In June 1998, the subsidiaries of Grupo Aeroportuario del Pacífico, S.A.B. de C.V. were granted concessions by the Ministry of Communications and Transportation (“SCT”) to manage, operate and develop each of the Pacific Group’s 12 airports and benefit from the use of the airport facilities, for a 50-year term beginning November 1, 1998. The cost of the concessions, which totaled Ps. 24,210,213 (Ps. 15,938,360 nominal pesos), was determined by the Mexican Government in August 1999, based upon the price paid by Aeropuertos Mexicanos del Pacífico, S.A. de C.V. (“AMP”, the strategic stockholder of the Company) for its interests in GAP. On August 20, 1999, GAP entered into a Liabilities Assumption Agreement with each of its subsidiaries, whereby it assumed the liabilities incurred by each subsidiary derived from obtaining the concession. Such liabilities were capitalized by GAP as equity in favor of the Mexican Government on such date.

The term of the concession may be extended under certain circumstances by the SCT, for terms not to exceed an additional 50 years. Beginning on November 1, 1998, the Company is required to pay an annual tax to the Mexican Government, through the SCT, for use of the public property, equivalent to 5% of each concessionaire’s annual gross revenues, according to the concession terms and the Mexican Federal Duties Law.

Title to all of the long-term fixed assets within the airports is retained by the Mexican Government. Accordingly, upon expiration of the term of the concessions granted to the Company, the assets, including all of the improvements made to the airport facilities during the term of the concessions, shall automatically revert to the Mexican Government. Additionally, ASA and other agencies of the Mexican Government maintain the rights to provide certain services such as air traffic control, fuel supply and immigration control.

b. Significant events

On February 24, 2006, the Company made an initial public offering of its Series “B” shares, under which the Mexican Government, which held 85% of the voting common stock of the Company sold its shares, both in the United States of America, via the New York Stock Exchange (under the symbol “PAC”), and in Mexico, via the Mexican Stock Exchange (under the symbol “GAP-B”). Consequently, as of such date, the Company became a public entity in both Mexico and the United States of America and is required to meet the various obligations and legal provisions applicable in each country for public entities.

7

On August 31, 2007, the Los Cabos, Puerto Vallarta, Hermosillo and Bajio airports signed an unsecured credit agreement with Banco Nacional de México, S.A. (Banamex) for Ps. 1,214 million. This amount will be available for disbursement in three separate tranches as follows: a) Ps. 600.0 million on September 7, 2007, b) Ps. 344.0 million at any time until January 31, 2008, and c) Ps. 270.0 million at any time until January 31, 2009. Amounts disbursed under the credit agreement will be used for financing capital investments, mainly those under the Master Development Program (as described in Note 17.b). Each borrowing matures seven years from the date of disbursement and bears fixed interest at a rate of 8.52% on unpaid balances. Interest payments and amortization of principal will be payable in 28 equal and consecutive quarterly payments beginning three months after the disbursement date; principal and interest are due on the same date. The Company has to comply with certain covenants and obligations as discussed in Note 12; such covenants do not impose cash restrictions.

On November 8, 2007, Corporativo de Servicios Aeroportuarios, S.A. de C.V. (“Corsa”) was incorporated as a subsidiary, in order to carry out a corporate restructuring.

On November 28, 2007, Puerta Cero Parking, S.A. de C.V. (“Parking”) was incorporated as a subsidiary. The purpose of this entity is to render operating and administrative services to the public parking lots. As of the date of these financial statements, this entity has not initiated operations.

2. Basis of Presentation

d. Comprehensive income – According to Bulletin B-4,Comprehensive Income, comprehensive income is comprised of the net income of the period, plus other comprehensive income (loss) items of the same period, which, in accordance with MFRS, are presented directly in stockholders’ equity without affecting the consolidated statements of income. For the years ended December 31, 2007, 2006 and 2005, comprehensive income is represented only by the net income of each period.

8

e. Classification of costs and expenses – Costs and expenses presented in the consolidated statements of income were classified according to their nature and to their importance in Company’s operations.

3. Summary of significant accounting policies

The accompanying consolidated financial statements have been prepared in conformity with MFRS, which require that management make certain estimates and use certain assumptions that affect the amounts reported in the financial statements and their related disclosures; however, actual results may differ from such estimates. The Company’s management, upon applying professional judgment, considers that estimates made and assumptions used were adequate under the circumstances. The significant accounting policies of the Company are as follows:

a. New Accounting Policies:

• Statement of income – Beginning January 1, 2007, the Company adopted new NIF B-3,Statement of Income, which now classifies revenues, costs and expenses as either ordinary or non-ordinary. Ordinary items are derived from primary activities representing an entity’s main source of revenues. Non-ordinary items are derived from activities other than those representing an entity’s main source of revenues. Consequently, the classification of certain transactions as special and extraordinary was eliminated; these items are now part of other income and expenses and non-ordinary items, respectively. Statutory employee profit sharing (“PTU”) should now be presented as an ordinary expense and no longer presented as a tax on income. According to Interpretation of Financial Information Standards (“INIF” for its initials in Spanish) Number 4,Presentation of Statutory Employee Profit Sharing in the Statement of Income, presentation of PTU should be included within other income and expenses. The main effect of adopting this INIF was the reclassification of current PTU for fiscal years 2006 and 2005 of Ps. 1,499 and Ps. 722, respectively, to other income and expenses.

• Related Parties – Beginning January 1, 2007, the Company adopted NIF C-13,Related Parties, which broadens the concept “related parties” to include a) the overall business in which the reporting entity participates; b) close family members of key management or prominent executives; and c) any fund created in connection with a labor-related compensation plan. NIF C-13 also requires the following disclosures: 1) that the terms and conditions of consideration paid or received in transactions carried out between related parties be equivalent to those of similar transactions carried out between independent parties and the reporting entity, only if sufficient evidence exists; and 2) benefits granted to the entity’s key management or prominent executives. The adoption of this standard did not have significant effects on the Company’s consolidated financial position or results of operations.

• Capitalization of comprehensive financing result – Beginning January 1, 2007, the Company adopted NIF D-6,Capitalization of Comprehensive Financing Result, which establishes general capitalization standards. Some of these standards include: a) mandatory capitalization of comprehensive financing result (“CFR”) directly attributable to the acquisition of qualifying assets; b) when financing in domestic currency is used to acquire assets, yields obtained from temporary investments before the capital expenditure is made are excluded from the amount capitalized; c) a methodology to calculate capitalizable CFR relating to funds from generic financing; d) regarding land, CFR may be capitalized if land is developed; and e) conditions that must be met to capitalize CFR and rules indicating when CFR should no longer be capitalized. In 2007, the Company capitalized CFR of Ps. 2,184 directly attributable to the acquisition of qualifying assets. Through 2006, CFR was charged to current earnings.

b. Reclassifications –For comparability with the consolidated balance sheet as of December 31, 2007, PTU payable at December 31, 2006 was reclassified as accounts payable.

9

c. Recognition of the effects of inflation –The Company restates its consolidated financial statements to Mexican peso purchasing power as of the most recent balance sheet date presented, thereby recognizing the effects of inflation in the financial information in conformity with Bulletin B-10,Recognition of the Effects of Inflation in Financial Information. The financial statements of the prior period have also been restated in terms of Mexican pesos of the latest period presented. The rates of inflation used to restate the consolidated financial statements as of and for the years ended December 31, 2006 and 2005 were 3.76% and 7.96%, respectively, which represents the inflation from those respective dates to December 31, 2007, based on the National Consumer Price Index (NCPI) published by the Central Bank of Mexico. Consequently, all financial statement amounts are comparable, both for the current and the prior periods, to the extent that all are stated in terms of Mexican pesos of the same purchasing power.

Procedures to recognize the effects of inflation in terms of Mexican pesos of purchasing power at the time of closing were as follows:

• Balance sheets:

Non-monetary assets are restated using a factor derived from the NCPI from the date of acquisition. Depreciation and amortization of restated asset values are calculated using the straight-line method based on the estimated economic useful life of each asset.

Common stock, legal reserve, retained earnings and the cumulative initial effect of deferred income taxes are restated using a factor derived from the NCPI, cumulative from the date of contribution or generation.

• Statements of income:

Revenues and expenses that are associated with monetary items (trade receivables, cash, liabilities, etc.) are restated from the month in which they arise through period-end, based on factors derived from the NCPI.

Other expenses related to the consumption of non-monetary items are restated when incurred based on the restated value of the corresponding asset from the date of consumption of the non-monetary asset through the end of the period, using factors derived from the NCPI.

Monetary position loss, which represents the erosion of the purchasing power of monetary items caused by inflation, is determined by applying to net monetary assets or liabilities, at the beginning of each month, the factor of inflation derived from the NCPI and is restated through period-end with the corresponding factor. Losses result from maintaining a net monetary asset position.

• Other statements:

The consolidated statements of changes in stockholders’ equity and changes in financial position present the changes in constant Mexican pesos, based on the financial position at prior year-end, restated to Mexican pesos as of the most recent year-end.

d. Cash and cash equivalents –This line item consists mainly of bank deposits in checking accounts and readily available daily investments of cash surpluses. This line item is stated at nominal value plus accrued yields, which are recognized in results as they accrue.

e. Financial investments for trading purposes – According to its intent, from the date of acquisition, the Company classifies its investments in marketable securities as held for trading purposes, because the Company has the intention to trade the debt and equity instruments in the short-term, before their maturity; these investments are stated at fair value and any fluctuations in the value of these investments are recognized within current earnings. The fair value is the amount at which a financial asset can be exchanged or a financial liability can be paid, among interested and willing parties in a free trade transaction.

10

f. Allowance for doubtful accounts –The Company systematically and periodically reviews the aging and collection of its accounts receivable and records an allowance for doubtful accounts when evidence exists that they will not be fully recoverable.

g. Buildings, building improvements, machinery and equipment –These assets are initially recorded at acquisition cost and are restated using factors derived from the NCPI. Depreciation is calculated using the straight-line method based on the useful lives of the related assets, as described in Note 7.

h. Airport concessions– Concessions to manage, operate and develop each of the airports are recorded at acquisition cost and restated using factors derived from the NCPI. Amortization is calculated using the straight-line method over the concession life of 50 years, as described in Note 8.

i. Rights to use airport facilities –Rights to use airport facilities are recorded at the nominal cost of the airport facilities as recorded by ASA and are restated using factors derived from the NCPI. Amortization is calculated using the straight-line method based on the remaining useful lives of the related assets, as described in Note 8.

j. Other acquired rights – Other acquired rights are recorded at acquisition cost and restated using factors derived from the NCPI. Amortization is calculated using the straight-line method over the period from the date of acquisition, as described in Note 10, to the end of the 50-year concession term.

k. Impairment of long-lived assets in use– The Company reviews the carrying amounts of long-lived assets in use, pursuant to Bulletin C-15,Accounting for the Impairment and Disposal of Long-Lived Assets, when an impairment indicator suggests that such amounts might not be recoverable. Impairment is recorded when the carrying amounts exceed the greater of the present value of future net cash flows or the net sales price upon disposal.

None of the 12 airports can be considered an “independent cash generating unit” since all are part of the Pacific Group package included in the Federal Government’s bidding process. Therefore, each concessionaire must operate its airports regardless of their individual results. Accordingly, the Company reviews its long-lived assets for impairment on a consolidated basis.

l. Embedded derivative instruments–When lease agreements establish rental payments in U.S. dollars and such currency is not the functional currency of both parties to the agreement, the embedded derivative, whose underlying is the U.S. dollar, is segregated and stated at fair value and is recorded as an embedded derivative asset or liability. Subsequent changes in the fair value of the derivative asset or liability are recognized in earnings.

m. Other assets – Costs incurred in the development phase that meet certain requirements and that the Company has determined will have future economic benefits are capitalized and amortized based on the straight-line method over five years. Disbursements that do not meet such requirements, as well as research costs, are recorded in results of the period in which they are incurred. Preoperating costs that meet certain requirements are capitalized and will be amortized over seven years using the straight-line method, beginning from the commencement of operations.

n. Provisions– Provisions are recognized for obligations that result from a past event, that are probable to result in the use of economic resources and that can be reasonably estimated; however, the final result could differ from that provision.

o. Employee retirement obligations– Liabilities from seniority premiums and severance payments at the end of the work relationship are recognized as costs over employee years of service and are calculated by independent actuaries using the projected unit credit method at net discount rates. Accordingly, the liability is being accrued which, at present value, will cover the obligation from benefits projected to the estimated retirement date of the Company’s employees.

p. Bank loans – Borrowings under the credit agreement are presented in current and long-term liabilities, depending on their maturity. Related interest expense is recognized in the period it occurs.

11

q. Revenue recognition –The majority of the Company’s revenues are derived from rendering aeronautical services, which are generally related to the use of airport facilities by airlines and passengers. These revenues are regulated by the SCT through a “maximum rate” by “workload unit”. A workload unit is currently equivalent to one terminal passenger or 100 kilograms (220 pounds) of cargo.

Revenues from non-aeronautical services consist mainly of the leasing of commercial space at the airport terminals (other than space deemed essential to airline operations), car parking, access fees charged to third parties providing food catering and other services at the airports, and other miscellaneous revenues.

Commercial space within the terminals is leased through operating lease agreements, based on either a monthly fixed rent or a charge based on the higher of a minimum monthly rent or a percentage of the lessee’s monthly revenues.

All revenues, except for the percentage of lessee monthly revenues on commercial rental contracts, are recognized within a maximum thirty-day term subsequent to the time passengers depart, planes land or other services are provided, as the case may be, considering that the events that occur and services that are rendered in any given month are invoiced and recognized within that same month. Revenues corresponding to the percentage of lessee monthly revenues on commercial rental contracts are recognized in the following month, with the exception of those revenues related to December, which are recognized within this same month.

r. Foreign currency transactions –According to the Mexican Federal Tax Code, foreign currency transactions are recorded at the exchange rate in effect on the day before the transaction date, published by the Central Bank of Mexico in the Federal Official Gazette (the difference between bank exchange rates in effect at the transaction date and the rates used by the Company is not considered material). Monetary assets and liabilities denominated in foreign currency are translated into Mexican pesos at the applicable exchange rate in effect at the balance sheet date. Exchange fluctuations are recorded as a component of net comprehensive financing result.

s. Statutory employee profit sharing – PTU is recorded in the results of the year in which it is incurred and presented under other income and expenses in the accompanying consolidated statements of income. Deferred PTU is derived from temporary differences between the accounting result and income for PTU purposes and is recognized only when it can be reasonably assumed that such difference will generate a liability or benefit, and there is no indication that circumstances will change in such a way that the liabilities will not be paid or benefits will not be realized.

t. Income taxes – Income tax is recorded in results of the year in which it is incurred. Beginning October 2007, and according to INIF 8,Effects of the Business Flat Tax, based on its financial projections, the Company must determine whether it will incur regular income tax or the new Business Flat Tax (“IETU”) and, accordingly, recognize deferred taxes based on the tax it will pay. Deferred income tax assets or liabilities are recognized for temporary differences resulting from comparing the accounting and tax bases of assets and liabilities plus any future benefits, if any, from tax loss carryforwards and certain tax credits. Deferred income tax assets are recorded only when there is high probability of recovery.

Tax on assets paid that is expected to be recovered is recorded as an advance payment of income tax and is presented in the consolidated balance sheets increasing the deferred income tax asset.

u. Earnings per share –Basic earnings per common share is calculated by dividing consolidated net income by the weighted average number of shares outstanding during the period. The Company does not have any dilutive securities; therefore basic and diluted earnings per share are the same. All weighted average number of shares outstanding used in per share calculations include the retroactive effects of the reduction of the number of shares (“reverse stock split”) described in Note 13.e.

v. Concentration of credit risk –Financial instruments that potentially expose the Company to a significant concentration of credit risk are primarily trade accounts receivable; however, management believes that such risk is adequately covered by the allowance for doubtful accounts.

b. In an Ordinary General Stockholders’ Meeting held on April 15, 2005, the stockholders declared cash dividends in the amount of Ps. 650,707 (Ps. 590,000 nominal pesos), which were paid on May 4, 2005.

c. In an Extraordinary General Stockholders’ Meeting held on April 15, 2005, the stockholders approved the conversion of 510,000,000 shares of fixed capital stock into equal shares of variable capital stock.

d. In an Ordinary General Stockholders’ Meeting held on April 27, 2005, the stockholders declared cash dividends in the amount of Ps. 485,272 (Ps. 440,000 nominal pesos), which were paid on June 3, 2005.

e. During an Extraordinary General Stockholders’ Meeting held on February 2, 2006, the stockholders approved the following:

(i) the conversion of all outstanding variable common stock into fixed common stock; and

(ii) a 1-for-28.55583444 reverse stock split of the Company’s outstanding common stock, reducing the number of shares outstanding at such date from 16,019,823,119 shares to 561,000,000 shares. All share, per share and option data in the accompanying consolidated financial statements and notes to the consolidated financial statements have been retroactively restated to reflect the reduction in the number of shares outstanding resulting from the reverse stock split for all periods presented.

f. In an Ordinary General Stockholders’ Meeting held on April 20, 2006, the stockholders declared cash dividends in the amount of Ps. 774,311 (Ps. 724,450 nominal pesos), which were paid on May 8, 2006.

18

h. In an Ordinary General Stockholders’ Meeting held on April 19, 2007, the stockholders declared cash dividends in the amount of Ps. 1,171,616 (Ps. 1,140,000 nominal pesos), which were paid on two different dates, Ps. 837,655 (Ps. 815,000 nominal pesos) on May 18, 2007 and Ps. 333,961 (Ps. 325,000 nominal pesos) on October 31, 2007.

i. The General Corporate Law requires that at least 5% of net income of the year be transferred to the legal reserve until the reserve equals 20% of capital stock at par value (nominal pesos). The legal reserve may be capitalized but may not be distributed, except in the form of stock dividends, until the entity is dissolved. The legal reserve must be replenished if it is reduced for any reason. At December 31, 2007 and 2006, the legal reserve, in nominal pesos was Ps. 196,988 and Ps. 152,268, respectively, amounts that represent 1.3% and 0.8% of the nominal value of capital stock, respectively.

j. Dividends paid to non-resident holders with respect to Series B shares and ADS’s are currently not subject to Mexican withholding tax. Dividends that are paid from a company’s distributable earnings that have not been subject to corporate income tax will be subject to a corporate-level dividend tax calculated on a gross-up basis by applying a factor of 1.4286 in 2005, 1.4085 in 2006 and 1.3889 thereafter. Corporate tax rates of 30% in 2005, 29% in 2006 and 28% thereafter are applied to the result. This corporate-level dividend income tax on the distribution of earnings may be applied as a credit against Mexican corporate income tax corresponding to the fiscal year in which the dividend was paid or against the Mexican corporate income tax of the two fiscal years following the date in which the dividend was paid. Dividends paid from a company’s distributable earnings that have been subject to corporate income tax are not subject to this corporate-level dividend income tax. According to the income tax law, the Company is responsible for the withholding and payment of the corporate-level dividend income tax.

k. The balances of stockholders’ equity tax accounts as of December 31 were as follows:

	2007		2006		2005

15. Transactions with related parties

Transactions with related parties, carried out in the ordinary course of business, were realized at prices comparable to those for transactions with independent parties and were as follows:

	2007		2006		2005
Revenues:
Revenues from aeronautical and non-aeronautical services invoiced to Cintra	Ps.	—	Ps.	91,444	Ps.	967,321

Concession taxes	Ps.	—	Ps.	25,253	Ps.	138,944

Through February 2006, Cintra, was considered a related party; however, subsequent to the sale of the Mexican Government’s participation in the Company as discussed in Note 1.b, Cintra was no longer considered a related party. Revenues invoiced to Cintra airlines include Ps. 74,786 and Ps. 803,625 of passenger charges for January and February 2006 and the year ended December 31, 2005, respectively.

In 1999, GAP and AMP entered into a technical assistance and transfer-of-technology agreement whereby AMP and its stockholders agreed to render administrative and advisory services and transfer industry technology and know-how to GAP in exchange for consideration. The agreement’s original 15-year term may be automatically renewed for successive five-year terms, unless one party gives a termination notice to the other at least 60 days prior to the effective termination date. If AMP and GAP decide to renew the agreement, GAP’s stockholder approval would be required.

According to the agreement, as of January 1, 2000, the Company committed to pay AMP annual consideration of U.S.$ 7,000,000 for the years 2000 and 2001 and, beginning in 2002, the greater of U.S.$ 4,000,000 or 5% of GAP’s consolidated operating income, calculated prior to deducting the technical assistance fee, depreciation and amortization (these amounts are subject to restatement based on the U.S. National Consumer Price Index (CPI)).

AMP is also entitled to the refund of expenses incurred in the rendering of the services provided for in the agreement.

As described in Note 1.a, according to the terms of the concessions and the Government Duties Law, the Company must pay the Mexican Government an annual tax for the rights to use airport facilities equivalent to 5% of each concessionaire’s annual gross revenues. Until February 2006, the payment of such tax to the Mexican Government was considered a transaction with a related party; however, subsequent to the sale of the Mexican Government’s participation in the Company in February 2006, it is no longer considered a related party.

20

The total amounts paid to executive officers were as follows:

	2007		2006		2005
Benefits paid	Ps.	15,950	Ps.	15,301	Ps.	15,073
Indemnification payments		329		1,541		86
Total	Ps.	16,279	Ps.	16,842	Ps.	15,159

In 2007, the Company implemented an incentive plan for certain key directors. The amount of the incentive paid is tied to the performance of the Company’s publicly traded stock. At December 31, 2007, no related compensation effect has been recorded in the accompanying financial statements as Company management determined the amount to be immaterial.

16. Income taxes

In accordance with Mexican tax law, the Company is subject to income tax, and through 2007, tax on assets. Income tax is computed taking into consideration the taxable and deductible effects of inflation, such as depreciation calculated on restated asset values. Taxable income is increased or reduced by the effects of inflation on certain monetary assets and liabilities through the inflationary component, which is similar to the gain or loss from monetary position. As of 2007, the tax rate is 28% and in 2006 and 2005, it was 29% 30%, respectively. Due to changes in the tax legislation, effective January 1, 2007, taxpayers who file tax reports and meet certain requirements may obtain a tax credit equivalent to 0.50% or 0.25% of taxable income. PTU paid is fully deductible.

In 2007, tax on assets was calculated by applying 1.25% to the value of the assets of the year, without deducting any liabilities. Through 2006 and 2005, tax on assets was calculated by applying 1.8% on the net average of the majority of restated assets less certain liabilities, including liabilities payable to banks and foreign entities. Tax on assets was payable only to the extent that it exceeded income tax payable for the same period.

On October 1, 2007, the Business Flat Tax Law (“LIETU”) was enacted and went into effect on January 1, 2008. In addition, the Tax Benefits Decree and the Third Omnibus Tax Bill were published on November 5 and December 31, 2007, respectively, clarifying or expanding the transitory application of the law regarding transactions carried out in 2007 that will have an impact in 2008. IETU applies to the sale of goods, the provision of independent services and the granting of use or enjoyment of goods, according to the terms of the IETU, less certain authorized deductions. IETU payable is calculated by subtracting certain tax credits from the tax determined. Revenues, as well as deductions and certain tax credits, are determined based on cash flows generated beginning January 1, 2008. IETU establishes that the tax rate will be 16.5% in 2008, 17% in 2009, and 17.5% as of 2010. The Asset Tax Law was repealed upon enactment of LIETU; however, under certain circumstances, tax on assets paid in the ten years prior to the year in which income tax is paid, may be refunded, according to the terms of the law. According to its financial projections and in accordance with INIF 8, the Company determined that it will pay income tax, and thereby recognized its deferred income taxes based on the regular income tax regime in the accompanying consolidated financial statements. Therefore, IETU did not result in adverse effects in current earnings.

a. Recoverable income tax on dividends

In 2002, certain subsidiaries declared dividends in favor of the Company for Ps. 175,173 (Ps. 142,939 nominal pesos). However, such dividends were not applied against the net income tax account and thus generated income tax of Ps. 93,915 (Ps. 76,969 nominal pesos), payable by the Company, according to Article 11 of the income tax law. Such amount was charged to retained earnings and paid to the tax authorities on December 17, 2002.

The Company subsequently considered that the above tax payment could have been credited against tax on assets for the year the subsidiaries declared the dividend, based on Article 9 of the Asset Tax Law.

As such, the Company decided to record the taxes paid as a long-term recoverable income tax and request the related refund. The recognition of this asset generated an additional credit in the 2002 statement of income, which was presented as part of income tax expense.

21

From 2002 through December 2007, the Company filed a request with the tax authorities for confirmation of the criteria under which it was requesting this refund and as well, requested the related refund.

As of the date of these financial statements, the following resolutions have been obtained: a) The Aguascalientes airport received a refund of Ps. 4,827 nominal pesos in 2005; b) At the La Paz airport, the refund was denied in the ultimate instance in 2006 and the airport recognized an expense of Ps. 5,104 nominal pesos to remove the previously recognized recoverable tax asset; c) In May 2007, the Puerto Vallarta airport decided to forego its case with respect to the refund and instead, determined that it would be able to recover the amount of Ps. 24,202 (nominal pesos) through recoverable asset tax paid. Accordingly, the recoverable tax asset was written off; however, given that the Company had a deferred tax asset recognized with respect to recoverable asset tax that was fully reserved, such valuation allowance was reversed now that the airport determined it would be able to recover the amount. Accordingly, no net effect occurred in current earnings as a result of this decision; d) In 2007, the Mexicali and Tijuana airports received unfavorable sentences, for which reason the Company decided to reserve Ps. 3,920 and Ps. 38,916, respectively. In spite of this, the Company will continue with the legal proceedings through the ultimate instance in an effort to obtain a favorable sentence. In that instance, the benefit would be recognized in earnings of the corresponding year.

In the case of the Tijuana airport, in May 2005, the Mexican Treasury Department issued a fine on the grounds that it considered the inclusion of this requested refund in the annual tax return to be inappropriate. As such, the airport paid Ps. 11,445 (nominal pesos), but filed a judicial annulment for refund of such fine, for which they received a favorable resolution in the ultimate instance. Thus, the Company must file a request for refund with the tax authorities.

b. Recoverable taxes

In 2003, the Company filed a request with the tax authorities regarding the confirmation of the criteria with respect to the basis that the Company can use to calculate the asset tax. The Company is requesting that such calculation, based on the interpretations of tax law as published by the Mexican Treasury Department, should only take into account the amount effectively paid by AMP for the shares of the Company that was reflected in the assets in each concession acquired through the bidding process. On April 23, 2004 and July 20, 2004 the Mexican Treasury Department (for the Aguascalientes, Hermosillo, La Paz, Los Mochis, Morelia and Mexicali airports, hereinafter referred to as the “Minor airports” and for the Guadalajara, Tijuana, Los Cabos, Puerto Vallarta, Bajío and Manzanillo airports, hereinafter referred to as the “Principal airports”, respectively) denied the criteria requested by the Company. Accordingly, the Company filed a judicial annulment.

On August 29, 2006, the Mexican Treasury Department confirmed the criteria for the Aguascalientes, Hermosillo, La Paz, Los Mochis, Morelia and Manzanillo airports, reducing the asset tax basis for these airports. Thus, for these airports, the base used to calculate tax on assets considers only the amount effectively paid by AMP for its 15% of the shares of the Company. This generated a recoverable tax as of December 31, 2006 for Ps. 190,537 (nominal pesos), plus Ps. 18,026 (nominal pesos) related to inflation, for a total recoverable asset of Ps. 208,563 (nominal pesos) recognized within the current recoverable income tax asset.

During 2007, the Company received a refund of Ps. 146,407 related to the airports, resulting in a pending balance of Ps. 62,156.

As of December 31, 2007 the judicial annulment for the Principal airports was still pending resolution.

e. At December 31, the main items comprising the deferred income tax asset are:

	2007			2006
Airport concessions and rights to use airport facilities	Ps.	221,760		Ps.	325,170
Trade accounts receivable		13,161			11,430

Recoverable tax on assets paid		739,682			711,156
		1,285,862			1,255,920

Valuation allowance for tax loss carryforwards		(116,966	)		(84,183	)
Net long-term deferred income tax asset	Ps.	1,047,619		Ps.	712,423

As a result of the enactment of IETU, the Company now has ten years, beginning in 2008 to recover existing asset tax credit carryforwards; as well, the LIETU established a mechanism to recover existing asset tax credit carryforwards that ultimately benefited the Company. Based on these changes which resulted in the Company’s ability to recover tax on assets that was previously determined to be unrecoverable, coupled with the Company’s financial projections from 2008 to 2017, in 2007, the Company recognized recoverable tax on assets paid in previous years for Ps. 354,897 (Ps. 286,361 nominal pesos), through the cancellation of the valuation allowance.

23

f. The actual amount of recoverable tax on assets paid in previous years amounts to Ps. 739,682. However, according to tax on asset and IETU laws, the recovery against income tax of the amount of tax on assets paid in the last ten years is limited to 10% per year. Therefore, the Company recognized a valuation allowance of Ps. 121,277, which results in net recoverable tax on assets of the following:

	Recoverable tax on assets for year 2007		Recoverable tax on assets from 2008 to 2017		Total
Bajío	Ps.	8,827	Ps.	3,773	Ps.	12,600
Guadalajara		69,924		124,854		194,778
Morelia		—		4,277		4,277
Puerto Vallarta		35,355		14,479		49,834
Tijuana		—		356,346		356,346
Grupo Aeroportuario del Pacífico, S.A.B. de C.V.		570		—		570
Total	Ps.	114,676	Ps.	503,729	Ps.	618,405

g. Additionally, the Company has generated Ps. 1,067,596 of net operating loss carryforwards. However, based on its financial projections, the Company expects that only those net operating loss carryforwards at the Aguascalientes, La Paz and Mexicali airports will be recoverable, which results in net operating loss carryforwards of Ps. 649,861. All tax loss carryforwards expire in 2048, as permitted by the Mexican tax authorities for concession operations.

17. Commitments

a. The Company has leased office space under three five-year operating lease agreements, effective as of February 2006, February 2003 and June 2006. The respective monthly rental payments are U.S.$ 20,807, U.S.$ 7,888 and U.S.$ 2,784. Base rent is subject to increases according to the NCPI and the CPI, respectively.

Lease expense was Ps. 4,746, Ps. 4,497 and Ps. 4,208 for the years ended December 31, 2007, 2006 and 2005, respectively.

b. On December 16, 2004, the SCT authorized the Company’s Master Development Program (MDP) update for the next five-year period from 2005-2009. The table below shows the investments to be made during this period, as approved by the SCT:

Year	MDP		Investment for handling checked-in luggage		Total amount
2005	Ps.	338,071	Ps.	308,843	Ps.	646,914
2006		424,697		—		424,697
2007		359,683		—		359,683
2008		311,560		—		311,560
2009		243,277		—		243,277
	Ps.	1,677,288	Ps.	308,843	Ps.	1,986,131

Amounts set forth above are expressed in thousands of Mexican pesos of purchasing power as of December 31, 2003, as the Company is currently discussing with SCT the determination of the correct inflation index to be used to restate such amounts as of December 31, 2007.

On February 2007, SCT authorized additional investments under the MDP of Ps. 151,883 at the Puerto Vallarta airport and Ps. 420,797 at the Los Cabos airport, representing nominal amounts at December 2003. The aggregate MDP, considering this additional capital expenditure is Ps. 2,558,811.

18. Contingencies

a. Several municipalities have filed real estate tax claims against some subsidiary concessionaires related to the land where the airports are located. Based on the opinion of its external legal counsel, the Company believes that there are no legal grounds for such claims. Therefore, the Company has initiated legal proceedings to invalidate the claims, and, where applicable, related foreclosures or other actions. Although no assurance can be given, the Company does not expect the resolutions to have any adverse effects on its consolidated financial position or results of operations.

In the case of the Mexicali airport, claims have been filed for Ps. 89 million (nominal pesos), which is guaranteed with an encumbrance on 25% of the daily revenues from the operation of the parking lot at the airport generated from November 2004 and until December 31, 2007. The cumulative amount of such encumbrances is Ps. 5.4 million (nominal pesos). During 2006, the Company received a favorable resolution in the first instance, which was appealed by the municipality. As of the date of these financial statements, the case is still pending resolution.

On June 8, 2005, the Tijuana airport received a second municipal real estate tax claim of Ps. 146,442 (nominal value), similar to municipal claims previously received by this and other airports, as described above. During 2005, the municipal authorities ordered the temporary encumbrance of certain assets at the Tijuana airport. On February 9, 2006, a bailment contract was issued on behalf of the Tijuana airport for Ps. 141,770 (nominal pesos) in order to release the encumbrance. As of the date of these financial statements, the case is still pending resolution.

b. On January 25, 2006, the Company entered into a line of credit which provides for the issuance of letters of credit up to an aggregate amount of Ps. 300,000 with a financial institution in order to guarantee all amounts claimed by the municipal authorities at its airports. Although no borrowings have been made against the line of credit, until its expiration in 2009, the Company’s airport subsidiaries are subject to certain financial covenants, including, among others, the requirement to (i) maintain a consolidated tangible net worth (defined as stockholders’ equity less intangible assets (including the Company’s concessions) and reserves for inflationary effects, in each case under MFRS) of at least Ps. 2,100,000, (ii) maintain a free and unencumbered cash reserve equal to the amount due on any outstanding letters of credit and (iii) maintain consolidated annual earnings before interest, income tax, depreciation and amortization of at least Ps. 1,000,000. As of the date of these financial statements, the Company has complied with all covenants.

c. In 1970, the Mexican Government expropriated a portion of land occupied by the Tijuana Airport, which was a rural property owned by a group of farmers (“Ejido”). The farmers have raised claims against the indemnity payments received from the Mexican Government. One such claim demands reversal of the land expropriation. While such claims are not actually against the Company, a favorable ruling on the return of the land might disrupt the current airport operation. According to the concession terms, access by the Company to land assigned to concessionaires is guaranteed. Therefore, the Company believes, although no assurance can be given, that the Mexican Government would be liable for any operational disruption caused by the farmers and would have to restore the concessionaire rights of use of public property. During 2007, the Ejido received an unfavorable resolution, which it appealed. As of the date of these financial statements, resolution of the appeal is still pending.

d. Federal, state and environmental protection laws regulate the Company’s operations. According to these laws, the passing of regulations relating to air and water pollution, environmental impact studies, noise control and disposal of dangerous and non-dangerous material has been considered. The Federal Environmental Protection Agency has the power to impose administrative, civil and criminal penalties against companies violating environmental laws. It is also entitled to close any facilities that do not meet legal requirements. As of the date of these financial statements the Company does not have any environmental sanctions against it.

25

e. In 2002, the Company settled a dispute with ASA related to administrative services provided to the Company during 1999. As a result of the settlement, the Company recorded a liability of Ps.70,924 (constant pesos) during 2002, which was ultimately paid to ASA during 2003. The Company considered these fees deductible for fiscal year 2003 and accordingly filed a request with the Mexican Treasury Department to confirm that such tax treatment was appropriate, regardless of the fact that the settlement took place in 1999.

As a result of a denial of the Company’s request by the Mexican Treasury Department, the Company filed for appeals at each airport. Since the date of these appeals, the Company has received favorable sentences in the ultimate instance as several airports. At the Aguascalientes and Morelia airports, however, unfavorable sentences in the ultimate instance were received, for which reason the Company has recognized a provision of Ps. 1,336 and Ps. 2,058, respectively, which include penalties and interest.

At six of its other airports, the Company has received a favorable sentence in the first instance. If the Company is not successful in such claims, it is expected that it may be required to pay Ps. 20.6 million, plus penalties and interest accumulated through the date of payment, in addition to provision already recognized as discussed above.

f. A claim has been filed against the Company by Remaconst, S.A. de C.V. concerning breach of a contract entered into between Remaconst and ASA, the Company’s predecessor, in 1992. As of the date of these financial statements, the Company has received a favorable sentence, which requires Remaconst to pay Ps. 17,222 as a maximum amount. However, the Company is still negotiating with Remaconst to define the terms and the total amount to be paid.

g. The users of airports, principally airlines, have been subject to increased costs following the September 11 events. Airlines have been required to adopt additional security measures and may be required to comply with more rigorous security guidelines in the future. Because a substantial majority of the Company’s international flights involve travel to the U.S., the Company may be required to comply with security directives of the U.S. Federal Aviation Authority, in addition to the directives of Mexican aviation authorities. The Mexican Government, being part of the International Civil Aviation Organization (“OACI”), indirectly accepted a resolution proposed by OACI related to requiring all checked baggage on all commercial flights beginning in January 2006 to undergo a comprehensive screening process. The new process is expected to require the installation of new screening equipment, which the Company will be required to purchase and operate. The Company cannot currently estimate the cost of compliance with the new screening guidelines. The Company could be required to undertake significant capital expenditures and ongoing operating expenses to comply with these requirements, which could restrict its liquidity and adversely affect its operating results. In addition, the Company may be exposed to a higher risk of liability as a result of the requirement that it directly operates this equipment.

h. Grupo de Ingeniería Universal, S.A. de C.V. (“GIUSA”), a contractor that carried out specific work at the Guadalajara International Airport, sued such airport, claiming non-compliance with the contract and other related agreements, as well as the payment of approximately Ps. 43 million and other unquantified benefits. The Company obtained favorable sentence in first instance, which was appealed by GIUSA. As of the date of these financial statements, resolution is still pending. Although no assurance can be provided, the Company considers that it has sufficient elements to obtain a favorable outcome.

19. Information by industry segment

The Company determines and evaluates its airports individual performances before allocating personnel-related costs and other costs incurred by Servicios a la Infraestructura Aeroportuaria del Pacífico, S.A. de C.V. (“SIAP”), the subsidiary relating to the Company’s senior management. All airports provide similar services to their customers. The following table shows a summary of the Company’s financial information by segment as it relates to the Guadalajara, Tijuana, Puerto Vallarta, Los Cabos, Hermosillo and Bajío airports. The financial information relating to the remaining six airports, as well as that of SIAP, Pacífico Cargo (until 2006), Corsa and Parking (since 2007), and the Company’s corporate operations (including investment in its subsidiaries) was combined and included under “Other”. The elimination of the investment of the Company in its subsidiaries is included under “Eliminations”.

20. Revenue

According to the General Law on Airports and its regulations, Company revenues are classified as airport, complementary and commercial services. Airport services generally include the use of airport runways, taxiways and parking areas for arriving and departing planes, use of passenger walkways, security services, hangars, and, in general, use of the space inside the terminal and other infrastructure by aircraft, passengers and cargo services. These services include rental of space that is vital for the operation of airlines and complementary service suppliers. Complementary services are ramps and handling services, catering, fuel supply, maintenance and repairs, and traffic and dispatch services.

27

Commercial services include services that are not essential for the operation of an airport, such as car parking areas, lease of space to retailers, restaurants and banks.

A price regulation system establishes a maximum rate for airport services and complementary services for each airport for each year in a five-year period. The maximum rate is the maximum amount of revenues per “work load unit” that may be earned at an airport each year from regulated sources. Under this regulation, a work load unit is equivalent to one passenger (excluding transit passengers) or 100 kilograms (220 pounds) of cargo.

During the periods ended December 31, 2007, 2006 and 2005, the Company charged up to 99.7%, 98.8% and 99.2% respectively, of the maximum rate.

For presentation purposes, revenues from access fees charged to third party providers of complementary services are classified as airport services. Below is a detail of the Company’s revenues for the years ended December 31, 2007, 2006 and 2005, respectively, according to the General Law on Airports and its regulations:

(1) Unregulated revenues are earned based on the terms of the Company’s operating lease agreements. Lease agreements are based on either a monthly rent (which generally increases each year based on the NCPI) or the greater of a monthly minimum guaranteed rent or a percentage of the lessee’s monthly revenues. Monthly rent and minimum guaranteed rent earned on the Company’s operating lease agreements are included under the caption “Commercial concessions” above. Revenues earned in excess of the minimum guaranteed rent are included in the “Revenues from sharing of commercial activities” caption above.

Future minimum rentals as of December 31, 2007, are as follows:

23. New accounting principles not yet in effect

In 2007, the Mexican Board for Research and Development of Financial Information Standards (CINIF) issued the following NIFs and INIFs, which became effective for fiscal years beginning on January 1, 2008:

NIF B-2, Statement of Cash Flows

NIF B-10, Effects of Inflation

NIF B-15, Translation of Foreign Currencies

NIF D-3, Employee Benefits

NIF D-4, Taxes on Income

INIF 5,  Recognition of the Additional Consideration Agreed to at the Inception of a Derivative Financial Instrument to Adjust it to Fair Value

INIF 6, Timing of Formal Hedge Designation

INIF 7,  Application of Comprehensive Income or Loss Resulting From a Cash Flow Hedge on a Forecasted Purchase of a Non-Financial Asset

Some of the significant changes established by these standards are as follows:

• NIF B-2, Statement of Cash Flows. This NIF establishes general rules for the presentation, structure and preparation of a cash flow statement, as well as the disclosures supplementing such statement, which replaces the statement of changes in financial position. NIF B-2 requires that the statement show a company’s cash inflows and outflows during the period. Line items should be preferably presented gross. Cash flows from financing activities are now presented below those from investing activities (a departure from the statement of changes in financial position). In addition, NIF B-2 allows entities to determine and present their cash flows from operating activities using either the direct or the indirect method.

30

• NIF B-10, Effects of Inflation. NIF B-10 defines two economic environments: a) inflationary environment, when cumulative inflation of the three preceding years is 26% or more, in which case, the effects of inflation should be recognized using the comprehensive method; and b) non-inflationary environment, when cumulative inflation of the three preceding years is less than 26%, in which case, no inflationary effects should be recognized in the financial statements. Additionally, NIF B-10 eliminates the replacement cost and specific indexation methods for inventories and fixed assets, respectively, and requires that the cumulative gain or loss from holding non-monetary assets be reclassified to retained earnings, if such gain or loss is realized; the gain or loss that is not realized will be maintained in stockholders’ equity and charged to current earnings of the period in which the originating item is realized.

• NIF B-15, Translation of Foreign Currencies.NIF B-15 eliminates classification of integrated foreign operations and foreign entities and incorporates the concepts of accounting currency, functional currency and reporting currency. NIF B- 15 establishes the procedures to translate the financial information of a foreign subsidiary: i) from the accounting to the functional currency; and ii) from the functional to the reporting currency, and allows entities to present their financial statements in a reporting currency other than their functional currency.

• NIF D-3, Employee Benefits.This NIF addresses current and deferred PTU. Deferred PTU should be calculated using the same methodology established in Bulletin D-4,Income Taxes, Tax on Assets and Statutory Employee Profit Sharing. It also includes the career salary concept and the amortization period of most items is reduced to five years, as follows:

Items will be amortized over a five-year period, or less, if employees’ remaining labor life is less than the:

• Beginning balance of the transition liability for severance and retirement benefits

• Beginning balance of past service cost and changes to the plan

• Beginning balance of gains and losses from severance benefits, according to actuarial calculations, should be amortized against the results of 2008

• Beginning balance of gains and losses from retirement benefits, according to actuarial calculations, should be amortized over a five-year period (net of the transition liability), with the option to fully amortize such item against the results of 2008.

• NIF D-4, Taxes on Income. This NIF relocates accounting for current and deferred PTU to NIF D-3, eliminates the permanent difference concept, redefines and incorporates various definitions and requires that the cumulative income tax effect be reclassified to retained earnings, unless it is identified with some of the other comprehensive income items that have not been applied against current earnings.

• INIF 5, Recognition of the Additional Consideration Agreed to at the Inception of a Derivative Financial Instrument to Adjust it to Fair Value. INIF 5 states that any additional consideration agreed to at the inception of a derivative financial instrument to adjust it to its fair value at that time should be part of the instrument’s initial fair value and not subject to amortization as established by paragraph 90 of Bulletin C-10,Derivative Financial Instruments and Hedging Activities. INIF 5 also establishes that the effect of the change should be prospectively recognized, affecting results of the period in which this INIF becomes effective. If the effect of the change is material, it should be disclosed.

• INIF 6, Timing of Formal Hedge Designation. INIF 6 states that hedge designations may be made as of the date a derivative financial instrument is contracted, or at a later date, provided its effects are prospectively recognized as of the date when formal conditions are met and the instrument qualifies as a hedging relationship. Paragraph 51.a) of Bulletin C- 10 only considered the hedge designation at the inception of the transaction.

31

• INIF 7, Application of Comprehensive Income or Loss Resulting From a Cash Flow Hedge on a Forecasted Purchase of a Non-Financial Asset. INIF 7 states that the effect of a hedge reflected in other comprehensive income or loss resulting from a forecasted purchase of a non-financial asset should be capitalized within the cost of such asset, whose price is set through a hedge, rather than reclassifying the effect to the results of the period affected by the asset, as required by Paragraph 105 of Bulletin C-10. The effect of this change should be recognized by applying any amounts recorded in other comprehensive income or loss to the cost of the acquired asset, as of the effective date of this INIF.

• On November 30, 2006, the International Financial Reporting Interpretations Committee (“IFRIC”) issued IFRIC 12,Service Concession Arrangements. The Interpretation addresses the accounting by private sector operators involved in the provision of public sector infrastructure assets and services, such as schools and roads. The Interpretation does not address the accounting for the government (grantor) side of such arrangements. Accounting for concessions is not specifically addressed in MFRS, for which reason IFRIC 12 will be applied supplementally in the Company’s consolidated financial statements.

At the date of issuance of these financial statements, the Company has not fully assessed the effects of adopting these new standards on its financial information.

24. Differences between MFRS and accounting principles generally accepted in the United States of America (“U.S. GAAP”)

The Company’s consolidated financial statements are prepared in accordance with MFRS, which differ in certain significant respects from U.S. GAAP.

(i) Airport concessions

Under MFRS, the cost of the concessions to operate the airports and the related facilities was allocated to two intangible assets: “right to use airport facilities” and “airport concessions.” “Airport concessions” represents the residual value after the allocation of cost to the “rights to use airport facilities.” The cost allocated to the “rights to use airport facilities” was determined based on the MFRS inflation-adjusted cost of the related fixed assets recorded in the accounts of ASA as of October 31, 1998. The remainder was allocated to airport concessions. The total value of the concession granted was determined by reference to the sale proceeds of the equity sold to AMP in August 1999. Consideration for the concessions to operate the facilities was provided by the issuance of the common stock of the Company.

The acquisition of the airport concessions and rights to use airport facilities was a transaction between entities under common control of the Mexican Government and did not involve cash consideration. U.S. GAAP requires that when assets are transferred between entities under common control, the receiving entity is required to initially recognize the assets at the carrying amount of the transferring entity on the date of transfer. As there was no nominal value recorded for the airport concessions between the SCT and ASA, there is no value assigned to the airport concessions for purposes of U.S. GAAP.

In addition, under MFRS, the airport concessions were deemed as concessions with a definite life and therefore have been amortized based on the concession term. Under US GAAP, such amortization has been reversed.

35

(ii) Amortization of assets under concession (treated as intangible “rights to use airport facilities” under MFRS)

As discussed above, according to MFRS, the cost of the concessions to operate the airport and the related facilities was allocated to two intangible assets: “rights to use airport facilities” and “airport concessions”.

For purposes of U.S. GAAP, since the concession arrangement provides the Company with the right to use the airports and related facilities for a 50-year term, and since the Company was created and controlled by the Mexican Government at the date the concessions were granted, the arrangement is accounted for based on its economic substance as a contribution by the Mexican Government of fixed assets including runways, aprons, platforms, buildings and other infrastructure, used to operate the airport facilities under the related concession agreements. Throughout the 50-year concession term, the Mexican Government retains title to the assets under concession. Upon expiration of the concession term, use of the assets reverts to the Mexican Government.

Because the transfer of fixed assets was made among entities under common control, for U.S. GAAP purposes, the related assets were recognized at their carrying value in the records of the Mexican Government, with remaining amortization terms as follows:

			Remaining amortization term (years)
Assets under concession allocated to:
Runways	Ps.	788,443	27
Land and buildings		2,289,740	17
Other infrastructure		138,596	2
	Ps.	3,216,779

In addition, as the transfer of fixed assets included land and buildings, the Company obtained an independent appraisal of all fixed assets under concession as of the date the concession was granted. Based on the appraisals, the fair value of the land was not considered significant in relation to the total fair value of all assets transferred. Accordingly, the land has been recorded as a single unit with the building and is amortized over the economic life of the building of 25 years. Amortization of the land component of the rights to use airport facilities under MFRS is over a period of 50 years. Thus, the difference in the amortization period results in increased amortization of the asset for purposes of the U.S. GAAP reconciliation.

As described in Notes 8 and 15 to the financial statements prepared under MFRS, the concession arrangements require the Company to pay a concession tax, pursuant to the Mexican Federal Duties Law, currently equal to 5% of annual gross revenues, which is classified within operating expenses. The Mexican Federal Duties Law is a law of general applicability and is not specifically directed to airport concession holders. The concession tax under the Mexican Federal Duties Law is applicable to and payable by any concession-holder that uses state-owned assets, without regard to the value of state-owned assets used. Accordingly, this annual payment is considered a tax rather than consideration paid in exchange for the Mexican Government’s contribution of the concessioned assets. Because taxes do not give rise to a liability until such time as they are incurred under U.S. GAAP, no additional obligation related to the contribution by the Mexican Government is recognized. No adjustment is made in the U.S. GAAP reconciliation for the concession tax; such tax is included within operating expenses, given that it is a tax assessed for the Company’s use of the concessions and is based on revenues generated by the concession.

(iii) Deferred fees for technical assistance services

In 1998, the Company granted a stock option to AMP to acquire an additional 5% of the shares of the Company provided that AMP complied with the terms of the technical assistance agreement. The option was exercisable in three tranches through August 25, 2006.

For U.S. GAAP purposes, the Company adopted Statement of Financial Accounting Standard (“SFAS”) No. 123(R),Share Based Payment,effective January 1, 2006, using the modified prospective application method, which applies to new awards, to any outstanding liability awards, and to awards modified, repurchased, or cancelled after January 1, 2006, as well as to the unvested portion of previously issued awards that remain outstanding at the initial date of adoption. SFAS 123(R) replaced SFAS No. 123,Accounting for Stock-Based Compensation, previously applied by the Company. SFAS No. 123(R) requires all stock-based compensation awards, including stock options, to be accounted for at fair value and to be recognized as compensation expense over the requisite service period.

36

Further, EITF 96-18,Accounting for Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services (EITF 96-18), provides guidance to establish a measurement date for awards issued other than to employees.

Based on the requirements in SFAS 123(R) and EITF 96-18, the Company established the measurement date with respect to the option agreement to AMP as being the date performance by AMP is complete, and consequently recognized the related cost of the award using variable accounting, as illustrated in FIN No. 28,Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans. Accordingly, as the service period over which AMP was required to provide technical assistance to the Company in order to be able to exercise the option was from August 1999 through August 2004, 100% of the compensation cost for the option award was recognized over such period. Accordingly, no additional compensation cost was recognized for the years ended December 31, 2007, 2006 and 2005. The option expired unexercised on August 25, 2006. The calculation of the cost related to the award was based on an initial estimated fair value of the option of U.S.$ 23,179 on August 25, 1999, inception of the award, which subsequently fell to U.S.$ 217 at August 25, 2004. The fair value of the award as of August 25, 2004, the last measurement date, was based on an independent appraisal, determined using the Monte Carlo model.

In addition to the stock option, AMP also holds forfeitable shares of GAP common stock in a trust. Upon AMP’s initial acquisition in 1999 of 15% of GAP’s common stock, which represented 100% of the Series “BB” shares of GAP, and pursuant to the terms of the participation agreement between GAP and AMP, AMP signed a trust agreement with Banco Nacional de Comercio Exterior, S.N.C. and assigned to the trustee all of the Series “BB” shares it acquired. In the trust agreement, GAP was named as secondary beneficiary only in the instance in which AMP does not comply with the terms of the technical assistance agreement, in which case 5% of the Series “BB” shares would be forfeited and sold, with the proceeds of the sale to be provided to GAP as liquidated damages and penalties. AMP may gradually sell the shares in increments over the 15-year term of its initial participation contract.

Based on the fact that the five percent of AMP’s initial investment held in the trust is forfeitable, subject to compliance with the technical assistance agreement, the Company considers those shares to be compensatory and has recorded the fair value of these compensatory shares in a manner consistent with the stock option, applying variable accounting, resulting in a related expense and corresponding addition to additional paid-in capital of Ps. 25,762, Ps. 47,810 and Ps. 15,887 for the years ended December 31, 2007, 2006 and 2005, respectively. Such amount is included with the cost of the stock option in the U.S. GAAP reconciliation under the caption deferred fees for technical assistance services.

(iv) Recognition of the fair value of embedded derivative instruments

As part of its ongoing operations, the Company enters into operating lease agreements to lease commercial space in its airport terminals. Certain leases are priced in U.S. dollars while the functional currency of both the Company and the tenants to whom commercial airport terminal space is leased is the Mexican peso.

The U.S. dollar foreign currency component of these contracts meet the criteria under SFAS No. 133,Accounting for Derivative Instruments and Hedging Activities, as amended as embedded derivatives. The Company has determined that: i) the embedded derivatives are not clearly and closely related to the economic characteristics and risks of the host contracts (lease agreements) and ii) separate, stand-alone instruments with the same terms as the embedded derivative instruments would otherwise qualify as a derivative instruments, thereby requiring separation from the lease agreements and recognition at fair value. Such instruments do not qualify for hedge accounting under SFAS No. 133 and are thereby considered non-hedging derivatives. Accordingly, the embedded derivative should be recorded at fair value in the balance sheet, with changes in such fair value each period recorded to results of operations, classified according to nature of the item to which the embedded derivative instrument is related.

These contracts also represent embedded derivative instruments under MFRS. Although the Company adopted C-10 for MFRS purposes, a difference still arises between the accepted valuation methodologies of the embedded derivatives under U.S. GAAP and MFRS. The accepted valuation methodology under U.S. GAAP requires that at the inception of the contract, such embedded derivatives be “at-the-market” and thus, have a fair value equal to zero. At each subsequent reporting date, the embedded derivatives are adjusted to their fair value based on the difference between the forward curve rates on the monthly payments at the reporting date versus the forward curve rates on the monthly payments at the date of inception of the lease contract. Under MFRS, the embedded derivatives are valued from inception of the contract and at each reporting date based on the forward curve rates on the monthly payments at the reporting date versus the spot rate at the reporting date, applied to the future rentals receivable. This method effectively recognizes the present value of the changes in the exchange rates on the future rentals receivable.

37

Accordingly, the following adjustments are included in the reconciliation to U.S. GAAP:

• As of December 31, 2007 and 2006, the valuation methodology followed under MFRS results in an embedded derivative asset, while the corresponding U.S. GAAP methodology generates an embedded derivative liability. Accordingly, the difference between the values of the embedded derivatives recorded in the balance sheets under U.S. GAAP and MFRS are included the reconciliation of stockholders’ equity. Differences between related changes in the fair values of embedded derivatives are included in the reconciliation of net income.

• Lastly, the change in the fair value of the embedded derivatives under U.S. GAAP is classified as revenues, based on the nature of the item to which the embedded derivative instrument is related, while under MFRS, such amount is included in net comprehensive financing income.

A reconciliation of the adjustments for the recognition of the fair value of embedded derivatives is as follows:

	For the years ended December 31,
	2007		2006			2005
Amount recorded to net income under MFRS	Ps.	5,732	Ps.	1,850		Ps.	(21,907	)
Effect for change in fair value of embedded derivatives		3,374		(8,749	)		(9,574	)
Amount recorded to net income under U.S. GAAP	Ps.	9,106	Ps.	(6,899	)	Ps.	(31,481	)

(v) Preoperating costs

In 2002, the Company established a new subsidiary, Pacífico Cargo, which was to provide cargo and storage services to certain courier and freight companies at the Guadalajara airport. Accordingly, the subsidiary incurred various costs, including salaries, feasibility and marketing studies, insurance and various legal costs related to developing the cargo center. As of December 31, 2006, Pacífico Cargo was liquidated and the administration of the cargo operation was transferred to by the Guadalajara International Airport.

The preoperating expenses related to this subsidiary have been capitalized for purposes of MFRS, in accordance with Bulletin C-8,Intangibles, which permits the capitalization of certain project development costs that fulfill the criteria established for recognition as assets. The capitalized costs were amortized beginning in May 2007, the date the operation was placed into use, using the straight-line method over seven years.

As these costs are one-time activities related to the opening of the subsidiary, for purposes of U.S. GAAP, they are considered to be start-up costs, which are expensed in accordance with Statement of Position (SOP) 98-5,Reporting on the Costs of Start-Up Activities. Accordingly, for purposes of U.S. GAAP, the portion of preoperating costs capitalized under MFRS that fall within the criteria of SOP 98-5 was cancelled.

Additionally, the amortization of such costs under MFRS has been reversed in the U.S. GAAP reconciliation.

(vi) Legal gain contingency

As described in Note 16.a to the financial statements under MFRS, in May 2005 the Company paid a fine to the Mexican Treasury Department for Ps. 11,445 (nominal pesos) related to its request for refund on the taxes paid on dividends. Based on the advice of its legal counsel, the Company determined that such fine had no legal basis and as such, in the financial statements under MFRS, recorded the amount paid as a recoverable asset.

Under U.S. GAAP, such fine is considered a gain contingency. As realization of this amount is not assured beyond a reasonable doubt, recognition as an asset under U.S. GAAP is prohibited. Accordingly, the amount was included in other expenses for the year ended December 31, 2005.

(vii) Recoverable income taxes

As discussed in Note 16.a to the financial statements under MFRS, in 2002 the Company paid dividends, which generated Ps. 93,915 of income tax that was paid by the Company in 2002. As of December 31, 2002, the Company recorded a deferred tax asset for the income taxes paid, as the amount can be used to offset future income tax payable.

38

Additionally, based on the advice of its legal counsel, the Company considered that the above tax payment could have been credited against tax on assets of the year, based on Article 9 of the Asset Tax Law. However, based on its future financial projections, the Company determined that the deferred tax asset generated by this credit would not be recoverable, for which reason it recognized a full valuation allowance on the deferred tax asset and instead, sought refund from the Mexican Tax Authorities. Under MFRS, a recoverable income tax asset was recognized with a corresponding credit to income tax expense for the year ended December 31, 2002.

Under U.S. GAAP, at that time, the recoverable income tax asset was considered a gain contingency and as realization was not assured beyond a reasonable doubt, recognition as an asset under U.S. GAAP was prohibited. Accordingly, the asset was eliminated in 2002, resulting in a reconciling item in the reconciliation of stockholders’ equity through December 31, 2006.

As mentioned in Note 16.a, in 2005, the Aguascalientes airport recovered Ps. 5,764 (Ps. 4,827 nominal pesos) of this recoverable income tax. Accordingly, for U.S. GAAP purposes, this amount represented the recognition of a gain contingency, for which reason it was included as other income in the U.S. GAAP reconciliation for the year ended December 31, 2005.

In 2006, the La Paz airport cancelled Ps. 5,296 (Ps. 5,104 nominal pesos) from the recoverable tax asset as a result of an unfavorable court resolution, as described in Note 16.a. Because this asset did not exist for purposes of U.S. GAAP, the amount was added back to income tax in the U.S. GAAP reconciliation for the year ended December 31, 2006.

In May 2007, at the Puerto Vallarta airport, the Company decided to forego its case with respect to a refund related to this tax. Instead, based on the favorable effects to the Company of changes in the tax law as discussed in Note 16.a, in that it would now be able to apply previously unrecoverable tax on assets against future earnings, the Company decided to write-off the recoverable tax asset of Ps. 30,587 (Ps. 24,202 nominal pesos) and reverse the valuation allowance on the existing deferred tax asset generated by the recoverable tax on assets. As a result, there was no net effect in earnings under MFRS. However, as mentioned above, the recoverable tax asset did not exist for purposes of U.S. GAAP given that it was a gain contingency. Accordingly, the reversal of the valuation allowance on the deferred tax asset for U.S. GAAP purposes resulted in a deferred tax benefit within the U.S. GAAP reconciliation for the year ended December 31, 2007.

Additionally, at the Mexicali and Tijuana airports, the recoverable tax asset was cancelled for Ps. 4,783 (Ps. 3,920 nominal pesos) and Ps. 47,485 (Ps. 38,916 nominal pesos), respectively, through income tax expense, as described in Note 16.a., given the unfavorable sentences received in those cases. Because this recoverable tax asset did not exist for purposes of U.S. GAAP, the amount is added back to income tax in the U.S. GAAP reconciliation for the year ended December 31, 2007 in order to reverse the write-off of the asset. Because the Company continues to proceed with its legal case, such amount is considered an unrecognized tax benefit as discussed in insert (ix) below.

(viii) Deferred income taxes

Under MFRS, the Company recognizes income taxes based on Statement D-4,Accounting for Income Taxes, Asset Taxes and Statutory Employee Profit Sharing, which requires the application of a methodology similar to SFAS No. 109,Accounting for Income Taxes (SFAS No. 109).

The deferred tax adjustments required to reconcile net income and stockholders’ equity under MFRS to U.S. GAAP as of and for the years ended December 31, 2007, 2006 and 2005 result from the differences in accounting for the cost of airport concessions, amortization of assets under concession, recognition of the fair value of embedded derivative instruments, effects of the removal of the transition obligation for severance payments and the effect of preoperating costs, as explained in previous paragraphs.

For U.S. GAAP purposes, there is no accounting basis for the airport concessions. However, a tax basis exists for Mexican statutory tax purposes, which results in an increase to the long-term deferred tax asset related to concessions. Additionally, because of the difference in the amortization rates of land for purposes of U.S. GAAP and MFRS, a different accounting basis exists under each set of accounting principles, thereby decreasing the long-term deferred tax asset recorded in the financial statements under MFRS. The effect was an increase to the deferred tax asset of Ps. 4,998,414 and Ps. 5,111,459 as of December 31, 2007 and 2006, respectively, and a related charge to net income of Ps. 113,045, Ps. 117,400 and Ps. 121,854 for the years ended December 31, 2007, 2006 and 2005, respectively.

39

Under both MFRS and U.S. GAAP, the change in the deferred tax asset resulting from the effects of accounting for inflation is recorded as a component of income tax expense.

Under MFRS, net deferred tax assets and liabilities are classified as non-current. Under U.S. GAAP, classification is based on the classification of the related asset or liability for financial reporting. A reconciliation of the net deferred income tax asset from MFRS to U.S. GAAP and the composition of the net deferred income tax asset under U.S. GAAP at December 31 were as follows:

	2007			2006
Reconciliation of deferred income tax asset:
Net deferred income tax asset under MFRS	Ps.	1,047,619		Ps.	712,423
Effect of cost of airport concessions		4,933,597			5,054,420

A reconciliation of the Mexican statutory tax rate to the Company’s effective tax rate under U.S. GAAP is as follows:

	For the years ended December 31,

(ix) Accounting for Uncertainty in Income Taxes

In July 2006, the Financial Accounting Standards Board (“FASB”) issued Interpretation 48,Accounting for Uncertainty in Income Taxes (“FIN 48”), which sets out a framework for preparers to use to determine the appropriate level of tax reserves to maintain for uncertain tax positions. This interpretation of FASB Statement No. 109,Accounting for Income Taxes, uses a two-step approach wherein a tax benefit is recognized if a position is more likely than not to be sustained. The amount of the benefit is then measured to be the highest tax benefit that is greater than 50 percent likely to be realized. FIN 48 also sets out disclosure requirements to enhance transparency of an entity’s tax reserves.

The Company adopted FIN 48 as of January 1, 2007. As a result, it performed an exhaustive analysis over all open tax years that remain subject to examination by the Mexican Tax Authorities, 2002 through 2007, in order to identify any uncertain tax position in any open tax year that could result in an unrecognized tax benefit. The following table summarizes the Company’s unrecognized tax benefits for 2007:

	Liabilities for unrecognized tax benefits 2003		Unrecognized tax benefits 2002			Total unrecognized tax benefits
Balance, January 1, 2007	Ps.	—	Ps.	128,962		Ps.	128,962
Increases in prior year positions		1,863		—			1,863
Decreases in prior year positions		—		(30,587	)		(30,587	)
Balance, December 31, 2007	Ps.	1,863	Ps.	98,375		Ps.	100,238

The liability for unrecognized tax benefits results from the fees paid to ASA for services provided to the Company from 1999 to 2003, that were deducted by the Company in 2003, as discussed in Note 18.e. Given that unfavorable sentences were received in the cases of the Aguascalientes and Morelia airports, the Company was not able to substantiate technical merits for the deductibility taken in its previous return and thus recognized a liability.

The unrecognized tax benefits arise from the tax positions taken by the Company with respect to: (i) dividend tax paid during 2002 for Ps. 83,411, as discussed in insert (vii); and (ii) the base over which tax on assets is calculated for Ps. 45,551, related to the Principal airports, as discussed in Note 16.b to the financial statements; given that the Company is still in legal proceedings with respect to these airports, and does not believe technical merit exists to be able to recognize the benefit.

Included in the total unrecognized tax benefits are Ps. 6,646 of tax benefits that if recognized, would decrease the Company’s effective tax rate.

The Company’s policy is to recognize interest and penalties within operating expense. During the year ended December 31, 2007, the Company recognized approximately Ps. 1,135 and Ps. 396, respectively in interest and penalties.

(x) Severance benefits

Under MFRS, beginning in January 2005, the Company adopted the revised provisions to Bulletin D-3, which require the recognition of a liability for severance payments, calculated based on actuarial computations. The same recognition criteria under U.S. GAAP is established in SFAS No. 112,Employers’ Accounting for Postemployment Benefits, which has been effective since 1994. However, upon the adoption of Bulletin D-3,Labor Obligations, the Company recognized a transition obligation (as permitted by the Bulletin), which resulted in an intangible asset being recognized for MFRS to be amortized over the future service period of employees. Given that U.S. GAAP does not permit such transition obligation related to severance payments, the intangible asset and its related amortization represent a difference between U.S. GAAP and MFRS presented in the accompanying U.S. GAAP reconciliation.

41

During 2006, the FASB issued SFAS No. 158,Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, which requires companies to fully recognize an asset or liability for the overfunded or underfunded status of their benefit plans, which in effect results in companies recognizing all previously unrecognized amounts. The Company does not have any other material unrecognized items related to its seniority premiums or severance payments that would require recognition under SFAS No. 158.

In addition, SFAS No. 132(R),Employers’ Disclosures about Pensions and Other Postretirement Benefits, requires certain disclosures, the majority of which have been disclosed in the financial statements under MFRS. However, SFAS No. 132(R) also requires a reconciliation of the beginning and ending balances of the benefit obligation, as follows:

	Severance Benefits
	2007			2006
Change in benefit obligation:
Benefit obligation at beginning of year	Ps.	33,323		Ps.	28,752
Service cost		5,131			5,183
Interest cost		1,266			1,246
Recognition of transition obligation		3,026			3,170
Benefits paid		(7,214	)		(5,028	)
Benefit obligation at end of year	Ps.	35,532		Ps.	33,323

Additional disclosure requirements

(a)Fair value of financial instruments:SFAS No. 107,Disclosures About Fair Value of Financial Instruments requires disclosure of fair value information about financial instruments whether or not recognized in the balance sheet, for which it is practicable to estimate fair value. Financial instruments include such items as cash and cash equivalents, marketable securities, accounts receivable, accounts payable and embedded derivative instruments.

The estimated fair value amounts as discussed below have been determined by the Company using available market information or other appropriate valuation methodologies that require considerable judgment in developing and interpreting the estimates of fair value. Accordingly, the estimates discussed herein and presented within the financial statements are not necessarily indicative of the amounts that the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

The carrying amounts of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate fair value because they have relatively short-term maturities and bear interest at rates tied to market indicators, as appropriate.

The fair value of the Company’s embedded derivative instruments was determined based on the mark-to-market value.

As mentioned in Note 12, the Company signed an unsecured credit agreement during 2007. Although such credit agreement contains a fixed interest rate, the Company believes that the carrying value is representative of its fair value, given that the loan was entered into based on an open bid with four separate banks.

(b) Comprehensive income: SFAS No. 130,Reporting Comprehensive Income, requires companies to report, in addition to net income, all other changes in their equity during a period resulting from transactions and other events and circumstances from nonowner sources, including all changes in equity during a period except those from investments by owners and distributions to owners. As the Company did not generate changes in equity from nonowner sources, the Company’s comprehensive income for the years ended December 31, 2007, 2006 and 2005, includes solely the net income of those respective periods.

(c) Earnings per share according to U.S. GAAP:In accordance with SFAS No. 128,Earnings Per Share, basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding. The computation of diluted earnings per share is adjusted to include any potential common shares. Potential common shares include the Company’s stock option (in 2005 and 2006 only, as the ability to exercise the option expired in 2006) as well as the forfeitable five percent of AMP’s shares held in the trust. All weighted average number of common shares outstanding and potential common shares include the effects of the one for 28.55583444 reverse stock split (see Note 13.e).

42

Diluted earnings per share for the years ended December 31, 2007, 2006 and 2005 include 4,207,500 equivalent shares from the forfeitable shares, which are considered to be contingently issuable under SFAS No. 128, and thereby are included in the calculation of diluted EPS until such time as the contingency is resolved.

The option to purchase 5,610,000 shares of common stock during 2006 and 2005, at a price of approximately U.S.$ 3.90 were not included in the computation of diluted EPS for the years ended December 31, 2006 and 2005, because the effect of such option would be anti-dilutive.

The computation and reconciliation of basic and diluted earnings per share for the years ended December 31, prepared in accordance with U.S. GAAP, are as follows:

	2007		2006		2005

Diluted earnings per share (Mexican pesos)	Ps.	3.1315	Ps.	2.0344	Ps.	1.7101

(d) Supplemental cash flow information:Under MFRS, the Company presents a consolidated statement of changes in financial position in accordance with Bulletin B-12,Statement of Changes in Financial Position, which identifies the generation and application of resources as the differences between beginning and ending financial statement balances in constant Mexican pesos.

For U.S. GAAP purposes, the Company has provided a statement of cash flows in accordance with SFAS No. 95,Statement of Cash Flows, which presents only cash movements, excluding the effects of inflation, and requires that additional information related to non-cash investing and financing transactions and other events be provided separately. Presented below are statements of cash flows of the Company in accordance with U.S. GAAP for the years ended December 31:

(f) Recently issued accounting standards (U.S. GAAP)

In September 2006 the FASB issued SFAS No. 157Fair Value Measurements. SFAS 157 defines fair value, establishes a framework for measuring fair value in accordance with U.S. GAAP, and expands disclosures about fair value measurements. This statement clarifies the definition of exchange price as the price between market participants in an orderly transaction to sell an asset or transfer a liability in the market in which the reporting entity would transact for the asset or liability, that is the principal or most advantageous market for the asset or liability. The changes to current practice resulting from the application of this statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 for financial assets and liabilities such as derivatives measured at fair value under SFAS No. 133,Accounting for Derivative Instruments and Hedging Activities. SFAS No. 157 has been deferred until fiscal years beginning after November 15, 2008 for nonfinancial assets and liabilities such as asset retirement obligations measured at fair value at initial recognition, long-lived asset groups measured at fair value under SFAS No. 144,Accounting for the Impairment or Disposal of Long-Lived Assets, liabilities for exit or disposal activities measured at fair value under SFAS No. 146,Accounting for Costs Associated with Exit or Disposal Activities, etc. The adoption of this standard is not expected to have a material impact on Company’s consolidated financial position, results of operations or cash flows.

In February 2007, the FASB issued SFAS No. 159The Fair Value Option for Financial Assets and Financial Liabilities - Including an amendment of FASB Statement No. 115, which permits entities to choose to measure many financial instruments and certain other items at fair value at specified election dates. Unrealized gains and losses on items for which the fair value option has been elected will be recognized in earnings at each subsequent reporting date. SFAS 159 provides entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 is for fiscal years beginning after November 15, 2007. The adoption of this standard is not expected to have a material impact on Company’s consolidated financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141 (revised 2007)Business Combinations – a replacement of FASB No. 141. SFAS 141(R) establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree at fair value as of the acquisition date. The Statement also establishes disclosures requirements which will enable users to evaluate the nature and financial effects of the business combination. SFAS 141(R) is effective for fiscal years beginning on or after December 15, 2008. The Company has not yet determined the impact, if any, of the adoption of FAS 141(R) on its consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161,Disclosures about Derivative Instruments and Hedging Activities, which enhances the current disclosure framework in SFAS No.133,Accounting for Derivative Instruments and Hedging Activities. SFAS No.161 primarily requires (i) qualitative disclosures about objectives and strategies for using derivatives in the context of each instrument’s primary underlying risk exposure; (ii) quantitative disclosures about the location and fair value amounts of and gains and losses on derivative instruments, in a tabular format; and (iii) disclosures about credit-risk-related contingent features in derivative agreements. This statement is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. This Statement encourages, but does not require, comparative disclosures for earlier periods at initial adoption. The Company is in the process of determining the effects of this new standard on its consolidated financial information.

25. Subsequent events

a. During January 2008, the Company carried out a corporate restructuring through the establishment of Corsa. As a result, on January 1, 2008, employees ceased their employment with the individual airports and became employees of Corsa. Corsa assumed all labor obligations. The Company provisioned Ps. 28,000 as of December 31, 2007 for the costs related to the assumed obligation, which were paid during February 2008.

b. In connection with judicial annulment filed by the Mexican Tax Authorities against the Principal airports described in Note 16.b, on January 8, 2008, the Company received a resolution indicating that these airports must calculate their asset tax base considering the total assets at each airport (including the 100% of the concession). However, this sentence requested the Mexican Tax Authorities to define and communicate to the Company the legal bases why they are unable to confirm the criteria related to the calculation of IMPAC; the Company filed an annulment against this sentence in January 2008.

c. On January 12, 2008, the Tijuana airport recovered the administration of the parking lot of the airport, which was formerly operated by a third party through a leasing contract that expired on the date mentioned. As of such date, the airport will administer the parking lot directly.

d. On January 30, 2008, the Bajío, Hermosillo, Puerto Vallarta and Los Cabos airports borrowed Ps. 344,000 under the line of credit with Banamex. The characteristics of the credit, amortization of principal, payment of interest and other terms are the same as those described in Note 1.b.

e. On March 3, 2008, by means of judicial agreement, the Company reached an agreement with Remaconst (Note 18.f), whereby Remaconst is committed to a total payment of Ps. 8,000, of which Ps. 2,978 will be paid through an exchange of assets and Ps. 5,022 will be payable in equal monthly payments during four years, beginning in March 2008, bearing an annual interest rate of 9.26% on unpaid balances.

f. On March 25, 2008, the Tijuana airport received an initial ruling declaring null and void the payment required by Municipal authorities it made, as discussed in Note 18.a.

45

g. With respect to the claim described in Note 18.e, on April 8, 2008, the Hermosillo airport received a fiscal resolution which requires the airport to pay PTU of Ps. 4,322. However, management believes there is no legal basis for this resolution, thus, the Hermosillo airport filed a judicial annulment on April 15, 2008.

26. Financial statements issuance authorization

On March 14, 2008 the issuance of the consolidated financial statements was authorized by Jorge Manuel Sales Martínez, Chief Executive Officer and by Rodrigo Guzmán Perera, Chief Financial Officer, subsequent to which additional disclosures related to subsequent events were included in Note 25. These consolidated financial statements were approved at the ordinary stockholders’ meeting on April 29, 2008.
