The sum of cost of airport services and general and administrative expenses (G&A) decreased 6.6%, mainly due to a decrease in professional fees and payroll expenses.

Notes to the Financial Information

Financial statements are prepared in accordance with International Financial Reporting Standards (“IFRS”), and presented in accordance with IAS 34 “Interim Financial Reporting.”

Unless stated otherwise, all comparisons of operating or financial results are made with respect to the comparable prior year period. The exchange rates used to convert foreign currency amounts were Ps. 18.3445 as of March 31, 2018, Ps. 19.6566 as of December 31, 2018 and Ps. 19.3793 as of March 31, 2019.

Adjusted EBITDA and Adjusted EBITDA margin: OMA defines Adjusted EBITDA as EBITDA less construction revenue plus construction expense and maintenance provision. We calculate the Adjusted EBITDA margin as Adjusted EBITDA divided by the sum of aeronautical revenue and non-aeronautical revenue. Construction revenue and construction cost do not affect cash flow generation and the maintenance provision corresponds to capital investments. OMA defines EBITDA as net income minus net comprehensive financing income, taxes, and depreciation and amortization. Neither Adjusted EBITDA nor EBITDA should be considered as an alternative to net income as an indicator of our operating performance, or as an alternative to cash flow as an indicator of liquidity. It should be noted that neither Adjusted EBITDA nor EBITDA is defined under IFRS, and may be calculated differently by different companies.

Capital investments: includes investments in fixed assets (including investments in land, machinery, and equipment) and improvements to concessioned properties under the Master Development Plan (MDP) plus strategic investments.

Construction revenue, construction cost: IFRIC 12 “Service Concession Arrangements” addresses how service concession operators should account for the obligations they undertake and rights they receive in service concession arrangements. The concession contracts for each of OMA’s airport subsidiaries establishes that the concessionaire is obligated to carry out improvements to the infrastructure transferred in exchange for the rights over the concession granted by the Federal Government. The latter will receive all the assets at the end of the concession period. As a result the concessionaire should recognize, using the percentage of completion method, the revenues and costs associated with the improvements to the concessioned assets. The amount of the revenues and costs so recognized should be the price that the concessionaire pays or would pay in an arm’s length transaction for the execution of the works or the purchase of machinery and equipment, with no profit recognized for the construction or improvement. The application of IFRIC 12 does not affect operating income, net income, or EBITDA, but does affect calculations of margins based on total revenues.

Passengers and Terminal passengers: All references to passenger traffic volumes are to Terminal passengers, which includes passengers on the three types of aviation (commercial, charter, and general aviation), and excludes passengers in transit.
