Definitions

Concession Services Agreements (IFRIC 12 interpretation). In Mexico and Puerto Rico, ASUR is required by IFRIC 12 to include in its income statement an income line, "Construction Revenues," reflecting the revenue from construction of, or improvements to concessioned assets made during the relevant period. The same amount is recognized under the expense line "Construction Costs" because ASUR hires third parties to provide construction services. Because equal amounts of Construction Revenues and Construction Costs have been included in ASUR's income statement as a result of the application of IFRIC 12, the amount of Construction Revenues does not have an impact on EBITDA, but it does have an impact on EBITDA Margin. In Colombia, "Construction Revenues" include the recognition of the revenue to which the concessionaire is entitled for carrying out the infrastructure works in the development of the concession, while "Construction Costs" represents the actual costs incurred in the execution of such additions or improvements to the concessioned assets. 

Majority Net Income reflects ASUR's equity interests in each of its subsidiaries and therefore excludes the 40% interest in Aerostar that is owned by other shareholders. Other than Aerostar, ASUR owns (directly or indirectly) 100% of its subsidiaries.

EBITDA means net income before provision for taxes, deferred taxes, profit sharing, non-ordinary items, participation in the results of associates, comprehensive financing cost, and depreciation and amortization. EBITDA should not be considered as an alternative to net income, as an indicator of our operating performance, as an alternative to cash flow or as an indicator of liquidity. Our management believes that EBITDA provides a useful measure that is widely used by investors and analysts to evaluate our performance and compare it with other companies. EBITDA is not defined under U.S. GAAP or IFRS and may be calculated differently by different companies.

Adjusted EBITDA Margin is calculated by dividing EBITDA by total revenues excluding construction services revenues for Mexico, Puerto Rico, and Colombia and excludes the effect of IFRIC 12 with respect to the construction of, or improvements to concessioned assets. ASUR is required by IFRIC 12 to include in its income statement an income line reflecting the revenue from construction of, or improvements to concessioned assets made during the relevant period. The same amount is recognized under the expense line "Construction Costs" because ASUR hires third parties to provide construction services. In Mexico and Puerto Rico, because equal amounts of Construction Revenues and Construction Costs have been included in ASUR's income statement as a result of the application of IFRIC 12, the amount of Construction Revenues does not have an impact on EBITDA, but it does have an impact on EBITDA Margin, as the increase in revenues that relates to Construction Revenues does not result in a corresponding increase in EBITDA. In Colombia, construction revenues do have an impact on EBITDA, as construction revenues include a reasonable margin over the actual cost of construction. Like EBITDA Margin, Adjusted EBITDA Margin should not be considered as an indicator of our operating performance, as an alternative to cash flow or as an indicator of liquidity and is not defined under U.S. GAAP or IFRS and may be calculated differently by different companies.
