SELECTED FINANCIAL DATA

Our consolidated financial statements included in this annual report are prepared in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board, or the IASB.  We publish our consolidated financial statements in Mexican pesos.

References in this annual report on Form 20-F to “dollars,” “U.S. dollars” or “U.S.$” are to the lawful currency of the United States.  References in this annual report on Form 20-F to “pesos” or “Ps.” are to the lawful currency of Mexico.  This Form 20-F contains translations of certain peso amounts into U.S. dollars at specified rates solely for the convenience of the reader.  These translations should not be construed as representations that the peso amounts actually represent such U.S. dollar amounts or could be converted into U.S. dollars at the rate indicated.  Unless otherwise indicated, U.S. dollar amounts have been translated from Mexican pesos at an exchange rate of Ps. 13.065214.7348 to U.S.$ 1.00, the FIX exchange rate as reported by the Mexican Central Bank (Banco de México) on December 31, 2013.2014.

This annual report on 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 (220 pounds) of cargo.

The discussion in this annual report of aeronautical and non-aeronautical revenues in relation to our total revenues is not in accordance with IFRS because it excludes our construction revenues from such amounts.  Therefore, in reviewing this annual report, you should be aware that in several sections of this annual report we take into account only revenues that resulted in actual cash inflows for the year (which we categorize as aeronautical and non-aeronautical revenues) for ratios or comparative calculations.  Both of these categories of revenues are dependent, either directly or indirectly, on passenger traffic, while revenues from construction services under IFRS Interpretations Committee (“IFRIC”) 12, “Service Concession Arrangements,” are not dependent upon passenger traffic, but from the level of capital expenditures carried out at each airport.  Information reported using only revenues that generated cash inflows may be more useful for readers of this annual report because those revenues are driven by the key elements of our business: passenger traffic and our maximum tariffs.  The use of aeronautical and non-aeronautical revenues is more common in our industry, as they represent the revenues generated from our core operations, which are services provided to passengers, airlines and other third parties based on passenger traffic at our airports.  Additionally, management regularly reviews our aeronautical and non-aeronautical revenues as they provide representative information regarding our passenger traffic and actual cash flows, which allows us to compare such revenues over comparative periods as well as make projections about our expected future cash flows.  Finally, management reviews non-aeronautical revenues per terminal passenger excluding hotel services because hotel services are not necessarily driven by passenger traffic and therefore may not provide representative information with respect to passenger traffic.  This metric is not considered to be an IFRS metric, given its exclusion of certain revenues.  We indicate each instance in which we use only aeronautical and non-aeronautical
