l.Provisions
Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, when it is probable that the Company will be required to settle the obligation, and when a reliable estimate can be made of the amount of the obligation.
The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties associated with the obligation. When a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows.
The main provision recognized by the Company is for major maintenance for its concessioned assets, which is classified as current or noncurrent based on the estimated time period over which it expects to settle the obligation.
Major maintenance provisions
The Company is required to perform major maintenance activities to its airports as established by the concession provided by the Mexican Government, in order to preserve the infrastructure in optimal working condition. The estimated major maintenance costs are considered in the Company’s master development program, which is reviewed and updated every five years. The Company recognizes and measures the contractual obligations of major maintenance of infrastructure when accrued according to IAS 37 (Provisions, Contingent Liabilities and Contingent Assets) and IFRS Interpretation Committee 12 (Service Concession Arrangements), a portion is recorded as short-term and the remainder as long-term depending on the period in which the maintenance is expected to be performed. These contractual obligations to maintain and restore the infrastructure of airports are recognized as a provision in the consolidated statements of financial position and in the expenses of the current fiscal year, pursuant to estimates that are required to comply with the present obligation at the end of the reporting period. When the effect of the time value of money is material, the amount of the provision equals the present value of the expenditures expected to be required to settle the obligation. The carrying amount of the provision increases each period to reflect the passage of time and this increase is recognized as an expense. After initial recognition, provisions are reviewed at the end of each reporting period and adjusted to reflect current best estimates. Adjustments to provisions arise from three sources: (i) revisions to estimated cash flows (both in amount and timing); (ii) changes to present value due to the passage of time; and (iii) revisions of discount rates to reflect prevailing current market conditions.
In periods following the initial recognition and measurement of the maintenance provision at its present value, the provision is revised to reflect estimated cash flows being closer to the measurement date. The unwinding of the discount relating to the passage of time is recognized as a financing cost and the revision of estimates of the amount and timing of cash flows is a remeasurement of the provision and charged or credited as an operating item within the consolidated statements of income and other comprehensive income.
