index in accordance with the terms of our master development plan.(2)
    
    The master development plan for Cancun airport was modified in the fourth quarter of 2005 to
reflect our decision to build a new terminal rather than implement extensive expansion and
remodeling of existing terminals, and to reflect an accelerated timetable for the construction
of a second runway once the necessary land to construct it is received from the government.
The Ministry of Communications and Transportation approved the modified plan and recognized
Ps. 1,433 million in investments as of December 31, 2006. 27

##### Table of Contents



Methodology For Determining Future Maximum Rates
  
    
    Projections for the fifteen-year period of work load
units (each of which is equivalent to one passenger or 100
kilograms (220 pounds) of cargo), operating costs and
expenses (excluding amortization and depreciation) related
to services subject to price regulation.
    
    Projections for the fifteen-year period of capital
expenditures related to regulated services, based on air
traffic forecasts and quality of standards for services to
be derived from the master development plans.
    
    Reference values, which 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.

Special Adjustments to Maximum Rates
  
    
    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, or that we would make such a request.
    
    Macroeconomic conditions.A concession holder may
also 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 work load units
processed in the concession holders airport are less than
that projected when its maximum rates were determined. 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 as a result of the decline in
passenger traffic volume. There can be no assurance that
any request on these grounds would be approved, or that we
would make such a request.
    
    Increase in concession fee 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 required to review each concession holders compliance
with its master development plan (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 plan, 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 work load 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.

    Based on changes in the rates for calculating foreign exchange liabilities, as reported by
Banco de Mexico, the Mexican Central Bank, at the end of each period, which were as follows:
Ps. 11.1495 per U.S. dollar as of December 31, 2004, Ps. 10.6344 per U.S. dollar as of
December 31, 2005 and Ps. 10.8116 per U.S. dollar as of December 31, 2006.(2)
    
    Based on changes in the Mexican consumer price index from the previous period, as reported by
the Banco de Mexico. The Mexican consumer price index at year end was: 112.5500 in
2004, 116.3010 in 2005 and 121.0150 in 2006.(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 16, 2007.  
    
    Depreciation and amortization expense.We restate our non-monetary foreign 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 Mexican NIF requires 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 will be 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 Mexican NIF, our
comprehensive financing cost reflects gains or losses from foreign exchange, gains or
losses from monetary position and gains and losses from interest and, as a result is
impacted by both inflation and 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 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.

reflect our decision to build a new terminal rather than implement extensive expansion and
remodeling of existing terminals, and to reflect an accelerated timetable for the construction
of a second runway once the necessary land is received from the government. The Ministry of
Communications and Transportation approved the modified plan and recognized Ps. 1,433 million

Independent directors should meet alone in an executive session at least once a year. §303A.03
    
    Our non-management and independent directors are not required to meet in executive sessions and generally do not
do so. Executive sessions are not expressly recommended by the Mexican Code of Best Corporate Practices.None of our members of management are members of our Board of Directors nor our other committees, except for our

not required to satisfy the NYSE independence and other audit committee standards that are not prescribed by Rule
10A-3.The principal characteristics of our Audit Committee are as follows:

 MAJOR SHAREHOLDERS
 Tender Offer by Fernando Chico
Pardo On May 14, 2007 Agrupacion Aeroportuaria Internacional II, S.A. de C.V.,
an entity indirectly owned and controlled by Fernando Chico Pardo, made a
tender offer for the purchase in Mexico and the United States of America of up
to 127,950,001 Series B shares (including Series B shares represented by ADSs),
representing approximately 42.65% of the outstanding capital stock of ASUR. Thereafter, Agrupacion Aeroportuaria Internacional II, S.A. de C.V.,
resolved to waive the condition that it receive offers for at least 127,950,001
Series B shares and established that it would accept for purchase any number of
Series B shares (including Series B shares represented by ADSs) offered for
sale. On June 22, 2007, Mr. Chico Pardo informed ASUR that the final aggregate
number of ADSs that had been offered and accepted for payment in the tender
offer in the United States of America was 2,867,302 ADSs (representing
28,673,020 Series B shares) and that the aggregate number of Series B shares
offered and accepted for payment in the Mexican tender offer was 7,762,515. A total of 12.15% of the aggregate capital stock of ASUR was offered and
accepted for payment in the tender offer. The shares offered in the tender
offer include Series B shares and ADSs previously directly owned by Mr. Chico
Pardo and Copenhagen Airports. In connection with the tender offers, on June 18, 2007, ITA, through
Bancomext, notified ASUR of its decision to convert 22,050,000 Series BB shares
into 22,050,000 Series B shares. ASUR was informed that these shares were
transferred to Agrupacion Aeroportuaria Internacional, S.A. de C.V., an entity
owned and controlled by Mr. Chico Pardo, as a result of a de-merger agreement
between Mr. Chico Pardo and Copenhagen Airports. Capital Stock Structure  Percentage of totalNumber of Shares

community. Based on the opinion of outside counsel, management believes that there is no
legal basis for these claims and the Company intends to take legal action to have the
claims dismissed.
