Description of the business and summary of significant accounting policies |
Basis of preparation | Basis of preparation Statement of compliance These consolidated financial statements comprise the financial statements of the Company and its subsidiaries at December 31, 2017 and 2016 and for each of the three years in the period ended December 31, 2017, and were prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). Items included in the financial statements of each of the Company’s entities are measured using the currency of the primary economic environment in which the entity operates (“functional currency”). The presentation currency of the Company’s consolidated financial statements is the Mexican peso, which is used also for compliance with its legal and tax obligations. All values in the consolidated financial statements are rounded to the nearest thousand (Ps.000), except when otherwise indicated. The Company has consistently applied its accounting policies to all periods presented in these consolidated financial statements. The consolidated financial statements provide comparative information in respect of the previous period. Basis of measurement and presentation The accompanying consolidated financial statements have been prepared under the historical-cost convention, except for derivative financial instruments that are measured at fair value and investments in marketable securities measured at fair value through profit and loss (“FVTPL”). The preparation of the consolidated financial statements in accordance with IFRS requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and notes. Actual results could differ from those estimates.
Basis of consolidation | Basis of consolidation The accompanying consolidated financial statements comprise the financial statements of the Company and its subsidiaries. At December 31, 2017 and 2016, for accounting purposes the companies included in the consolidated financial statements are as follows:

*The Company has not started operations in Guatemala.
| (1) |  | With effect from August 3, 2016, the name of the Company was changed from Servicios Operativos Terrestres Volaris, S.A. de C.V. to Operaciones Volaris, S.A. de C.V.
The financial statements of the subsidiaries are prepared for the same reporting period as the parent Company, using consistent accounting policies. Control is achieved when the Company is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Company controls an investee if, and only if, the Company has:
| (i) |  | Power over the investee (i.e. existing rights that give it the current ability to direct the relevant activities of the investee).
| (ii) |  | Exposure, or rights, to variable returns from its involvement with the investee.
| (iii) |  | The ability to use its power over the investee to affect its returns.
When the Company has less than a majority of the voting or similar rights of an investee, the Company considers all relevant facts and circumstances in assessing whether it has power over an investee, including:
| (i) |  | The contractual arrangement with the other vote holders of the investee.
| (ii) |  | Rights arising from other contractual arrangements.
| (iii) |  | The Company’s voting rights and potential voting rights.
The Company re-assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses control of the subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated financial statements from the date the Company gains control until the date the Company ceases to control the subsidiary. All intercompany balances, transactions, unrealized gains and losses resulting from intercompany transactions are eliminated in full. On consolidation, the assets and liabilities of foreign operations are translated into Mexican pesos at the rate of exchange prevailing at the reporting date and their statements of profit or loss are translated at exchange rates prevailing at the dates of the transactions. The exchange differences arising on translation for consolidation are recognized in other comprehensive income (“OCI”). On disposal of a foreign operation, the component of OCI relating to that particular foreign operation is recognized in profit or loss.
Revenue recognition | Revenue recognition Passenger revenues: Revenues from the air transportation of passengers are recognized at the earlier of when the service is provided or when the non-refundable ticket expires at the date of the scheduled travel. Ticket sales for future flights are initially recognized as liabilities under the caption unearned transportation revenue and, once the transportation service is provided by the Company or when the non-refundable ticket expires at the date of the scheduled travel, the earned revenue is recognized as passenger ticket revenues and the unearned transportation revenue is reduced by the same amount. All of the Company’s tickets are non-refundable and are subject to change upon a payment of a fee. Additionally, the Company does not operate a frequent flier program. Non-ticket revenues: The most significant non-ticket revenues include revenues generated from: (i) air travel-related services (ii) revenues from non-air travel-related services and (iii) cargo services. Air travel-related services include but are not limited to fees charged for excess baggage, bookings through the call center or third-party agencies, advanced seat selection, itinerary changes, charters and airport passenger facility charges for no-show tickets. They are recognized as revenue when the related service is provided by the Company. Revenues from non-air travel-related services include commissions charged to third parties for the sale of hotel rooms, trip insurance and rental cars. They are recognized as revenue at the time the service is provided. Additionally, services not directly related to air transportation include VClub membership fees and the sale of advertising to third parties. VClub membership fees are recognized as revenues over the term of the membership. Revenue from the sale of advertising is recognized over the period in which the service is provided. Revenues from cargo services are recognized when the cargo transportation is provided (upon delivery of the cargo to the destination). The breakdown of the Company’s non-ticket revenues for the years ended December 31, 2017, 2016 and 2015 is as follows:
|  | For the years ended December 31, |
|  | 2017 |  | 2016 |  | 2015 |
Air travel-related services |  | Ps. | 6,293,747 |  | Ps. | 5,055,836 |  | Ps. | 3,418,654 |
Non-air travel-related services |  | 589,338 |  | 494,864 |  | 441,393 |
Cargo |  | 170,973 |  | 171,621 |  | 189,292 |
Total non-ticket revenues |  | Ps. | 7,054,058 |  | Ps. | 5,722,321 |  | Ps. | 4,049,339 |
Cash and cash equivalents | Cash and cash equivalents Cash and cash equivalents are represented by bank deposits and highly liquid investments with maturities of 90 days or less at the original purchase date. For the purpose of the consolidated statements of cash flows, cash and cash equivalents consist of cash and short-term investments as defined above.
Financial instruments | Financial instruments A financial instrument is any contract that gives rise to a financial asset for one entity and a financial liability or equity instrument for another entity. The Company early adopted IFRS 9. Under IFRS 9 (2013), the FVTPL category used under IAS 39 remains permissible, although new categories of financial assets are introduced. These new categories are based on the characteristics of the instruments and the business model under which these are held, to either be measured at fair value or at amortized cost. For financial liabilities, categories provided under IAS 39 are maintened. As a result, there was no difference in valuation and recognition of the financial assets under IFRS 9 (2013), since those financial assets categorized under IAS 39 as FVTPL remain in that same category under IFRS 9 (2013). In the case of trade receivables, these were not affected in terms of the valuation model under this version of IFRS 9 (2013), since they are carried at amortized cost and continued to be accounted for as such. Also, the hedge accounting section of IFRS 9 (2013) requires, for options that qualify and are formally designated as hedging instruments, the intrinsic value of the option to be defined as the hedging instrument, thus allowing for the exclusion of changes in fair value attributable to extrinsic value (time value and volatility), to be accounted, under the transaction-related method, separately as a cost of hedging that needs to be initially recognized in OCI and accumulated in a separate component of equity, since the hedged item is a portion of the forecasted jet fuel consumption. The extrinsic value is recognized in the consolidated statement of operations when the hedged item is recognized in income. IFRS 9 requires the Company to record expected credit losses on all trade receivables, either on a 12 month or lifetime basis. The Company recorded lifetime expected losses on all trade receivables. i) Financial assets Classification of financial assets The Company determines the classification and measurement of financial assets, in accordance with the categories in IFRS 9 (2013), which are based on both: the characteristics of the contractual cash flows of these assets and the business model objective for holding them. Financial assets include those carried at FVTPL, whose objective to hold them is for trading purposes (short-term investments), or at amortized cost, for accounts receivables held to collect the contractual cash flows, which are characterized by solely payments of principal and interest (“SPPI”). Derivative financial instruments are also considered financial assets when these represent contractual rights to receive cash or another financial asset. Initial recognition All the Company’s financial assets are initially recognized at fair value, including derivative financial instruments. Subsequent measurement The subsequent measurement of financial assets depends on their initial classification, as is described below:
| 1. |  | Financial assets at FVTPL, which include financial assets held for trading.
| 2. |  | Financial assets at amortized cost, whose characteristics meet the SPPI criterion and were originated to be held to collect principal and interest in accordance with the Company’s business model.
| 3. |  | Derivative financial instruments are designated for hedging purposes under the cash flow hedge (“CFH”) accounting model and are measured at fair value.
Derecognition A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognized when:
| a) |  | The rights to receive cash flows from the asset have expired;
| b) |  | The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘pass-through’ arrangement; and either (i) the Company has transferred substantially all the risks and rewards of the asset, or (ii) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset; or
| c) |  | When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the asset is recognized to the extent of the Company’s continuing involvement in the asset. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.
ii) Impairment of financial assets The Company assesses, at each reporting date, whether there is objective evidence that a financial asset or a group of financial assets is impaired. An impairment exists if one or more events has occurred since the initial recognition of an asset (an incurred ‘loss event’), that has an impact on the estimated future cash flows of the financial asset or the group of financial assets that can be reliably estimated. Evidence of impairment may include indications that the debtors or a group of debtors is experiencing significant financial difficulty, default or delinquency in receivables, the probability that they will enter bankruptcy or other financial reorganization and observable data indicating that there is a measurable decrease in the estimated cash flows, such as changes in arrears or economic conditions that correlate with defaults. Further disclosures related to impairment of financial assets are also provided in Note 2(vi) and Note 8. For trade receivables, the Company records allowance for credit losses in accordance with the objective evidence of the incurred losses. Based on this evaluation, allowances are taken into account for the expected losses of these receivables. For the years ended December 31, 2017, 2016 and 2015, the Company recorded an impairment on accounts receivable of Ps.4,720, Ps.9,164 and Ps.8,825, respectively (Note 8). iii) Financial liabilities Classification of financial liabilities Financial liabilities under IFRS 9 (2013) are classified at amortized cost or at FVTPL. Derivative financial instruments are also considered financial liabilities when these represent contractual obligations to deliver cash or another financial asset. Initial recognition The Company determines the classification of its financial liabilities at initial recognition. All financial liabilities are recognized initially at fair value. The Company’s financial liabilities include accounts payable to suppliers, unearned transportation revenue, other accounts payable, financial debt and financial instruments. Subsequent measurement The measurement of financial liabilities depends on their classification as described below: Financial liabilities at amortized cost Accounts payable are subsequently measured at amortized cost and do not bear interest or result in gains and losses due to their short-term nature. After initial recognition at fair value (consideration received), interest bearing loans and borrowings are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process. Amortized cost is calculated by taking into account any discount or premium on issuance and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the consolidated statements of operations. This amortized cost category generally applies to interest-bearing loans and borrowings (Note 5). Financial liabilities at FVTPL FVTPL include financial liabilities designated upon initial recognition at fair value through profit or loss. Financial liabilities under the fair value option are classified as held for trading, if they are acquired for the purpose of selling them in the near future. This category includes derivative financial instruments that are not designated as hedging instruments in hedge relationships as defined by IFRS 9 (2013). During the years ended December 31, 2017, 2016 and 2015 the Company has not designated any financial liability as at FVTPL. Derecognition A financial liability is derecognized when the obligation under the liability is discharged or cancelled, or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the consolidated statements of operations. Offsetting of financial instruments Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statement of financial position if there is:
| (i) |  | A currently enforceable legal right to offset the recognized amounts, and
| (ii) |  | An intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.
Other accounts receivable | Other accounts receivable Other accounts receivables are due primarily from major credit card processors associated with the sales of tickets and are stated at cost less allowances made for credit losses, which approximates fair value given their short-term nature.
Inventories | Inventories Inventories consist primarily of flight equipment expendable parts, materials and supplies, and are initially recorded at acquisition cost. Inventories are carried at the lower of their cost and their net realization value. The cost is determined on the basis of the method of specific identification, and expensed when used in operations.
Intangible assets | Intangible assets Cost related to the purchase or development of computer software that is separable from an item of related hardware is capitalized separately and amortized over the period in which it will generate benefits not exceeding five years on a straight-line basis. The Company annually reviews the estimated useful lives and salvage values of intangible assets and any changes are accounted for prospectively. The Company records impairment charges on intangible assets used in operations when events and circumstances indicate that the assets or related cash generating unit may be impaired and the carrying amount of a long-lived asset or cash generating unit exceeds its recoverable amount, which is the higher of (i) its fair value less cost to sell, and (ii) its value in use. The value in use calculation is based on a discounted cash flow model, using our projections of operating results for the near future. The recoverable amount of long-lived assets is sensitive to the uncertainties inherent in the preparation of projections and the discount rate used in the calculation. For the years ended December 31, 2017, 2016 and 2015, there were no indicators of impairment. No impairment charges were recorded in respect of the Company’s value of intangible assets.
Guarantee deposits | Guarantee deposits Guarantee deposits consist primarily of aircraft maintenance deposits paid to lessors, deposits for rent of flight equipment and other guarantee deposits. Aircraft and engine deposits are held by lessors in U.S. dollars and are presented as current assets and non-current assets, based on the recovery dates of each deposit established in the related agreements (Note 11). Aircraft maintenance deposits paid to lessors Most of the Company’s lease agreements require the Company to pay maintenance deposits to aircraft lessors to be held as collateral in advance of the Company’s performance of major maintenance activities. These lease agreements provide that maintenance deposits are reimbursable to the Company upon completion of the maintenance event in an amount equal to the lesser of (i) the amount of the maintenance deposits held by the lessor associated with the specific maintenance event, or (ii) the qualifying costs related to the specific maintenance event. Substantially all of these maintenance deposits are calculated based on a utilization measure of the leased aircrafts and engines, such as flight hours or cycles, and are used solely to collateralize the lessor for maintenance time run off the aircraft and engines until the completion of the maintenance of the aircraft and engines. Maintenance deposits expected to be recovered from lessors are reflected as guarantee deposits in the accompanying consolidated statement of financial position. The portion of prepaid maintenance deposits that is deemed unlikely to be recovered, primarily relating to the rate differential between the maintenance deposits and the expected cost for the next related maintenance event that the deposits serve to collateralize, is recognized as supplemental rent in the consolidated statements of operations. Thus, any excess of the required deposit over the expected cost of the major maintenance event is recognized as supplemental rent in the consolidated statements of operations starting from the period the determination is made. For the years ended December 31, 2017, 2016 and 2015, the Company expensed as supplemental rent Ps.103,648, Ps.143,923 and Ps.73,258, respectively. Any usage-based maintenance deposits to be paid to the lessor, related with a major maintenance event that (i) is not expected to be performed before the expiration of the lease agreement, (ii) is nonrefundable to the Company and (iii) is not substantively related to the maintenance of the leased asset, is accounted for as contingent rent in the consolidated statements of operations. The Company records lease payment as contingent rent when it becomes probable and reasonably estimable that the maintenance deposits payments will not be refunded. During the year ended December 31 2017 and, 2016, the Company added five and 17 new net aircraft to its fleet, respectively. Some lease agreements of these aircraft do not require the obligation to pay maintenance deposits to lessors in advance in order to ensure major maintenance activities, so the Company does not record guarantee deposits regarding these aircraft. However, some lease agreements provide the obligation to make a maintenance adjustment payment to the lessors at the end of the contract period. This adjustment covers maintenance events that are not expected to be made before the termination of the contract. The Company recognizes this cost as a contingent rent during the lease term of the related aircraft, in the consolidated statement of operations. For the years ended December 31, 2017, 2016 and 2015, the Company expensed as contingent rent Ps.162,108, Ps.201,434 and Ps.290,857, respectively. The Company makes certain assumptions at the inception of the lease and at each consolidated statement of financial position date to determine the recoverability of maintenance deposits. These assumptions are based on various factors such as the estimated time between the maintenance events, the date the aircraft is due to be returned to the lessor, and the number of flight hours the aircraft and engines is estimated to be utilized before it is returned to the lessor. In the event that lease extensions are negotiated, any extension benefit is recognized as a deferred lease incentive. The aggregate benefit of extension is recognized as a reduction of rental expense on a straight-line basis, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. During the years ended December 31, 2017 and 2016, the Company extended the lease term of three and two aircraft agreements, respectively, and two engine agreements in 2017. These extensions made available to the Company maintenance deposits that were recognized in prior periods in the consolidated statements of operations as contingent rent of Ps.65,716 and Ps.92,528 during 2017 and 2016, respectively. The maintenance event for which the maintenance deposits were previously expensed was scheduled to occur after the original lease term and as such the contingent rental payments were expensed. However, when the leases were amended, the maintenance deposits amounts became probable of recovery due to the longer lease term and as such they are being recognized as an asset. The effect of these lease extensions were recognized as a guarantee deposit and a deferred aircraft and engine lease extension benefit in the consolidated statements of financial position at the time of lease extension. Because the lease extension benefits are considered lease incentives, the benefits are deferred in the statement of financial position and are being recognized on a straight-line basis over the remaining revised lease terms. For the years ended December 31, 2017, 2016 and 2015, the Company amortized Ps.88,224, Ps.74,748 and Ps.45,313, respectively, of lease incentives which was recognized as a reduction of rent expenses in the consolidated statements of operations.
Aircraft and engine maintenance | Aircraft and engine maintenance The Company is required to conduct diverse levels of aircraft maintenance. Maintenance requirements depend on the type of aircraft, age and the route network over which it operates. Fleet maintenance requirements may involve short cycle engineering checks, for example, component checks, monthly checks, annual airframe checks and periodic major maintenance and engine checks. Aircraft maintenance and repair consists of routine and non-routine works, divided into three general categories: (i) routine maintenance, (ii) major maintenance and (iii) component service. (i) Routine maintenance requirements consist of scheduled maintenance checks on the Company’s aircraft, including pre-flight, daily, weekly and overnight checks, any diagnostics and routine repairs and any unscheduled tasks performed as required. This type of maintenance events is currently serviced by the Company mechanics and are primarily completed at the main airports that the Company currently serves. All other maintenance activities are sub-contracted to qualified maintenance business partner, repair and overhaul organizations. Routine maintenance also includes scheduled tasks that can take from seven to 14 days to accomplish and typically are required approximately every 22 months. All routine maintenance costs are expensed as incurred. (ii) Major maintenance consists of a series of more complex tasks that can take up to six weeks to accomplish and typically are required approximately every five to six years. Major maintenance is accounted for under the deferral method, whereby the cost of major maintenance and major overhaul and repair is capitalized (leasehold improvements to flight equipment) and amortized over the shorter of the period to the next major maintenance event or the remaining contractual lease term. The next major maintenance event is estimated based on assumptions including estimated usage. The United States Federal Aviation Administration (“FAA”) and the Mexican Civil Aeronautic Authority (Dirección General de Aeronáutica Civil, or “DGAC”) mandate maintenance intervals and average removal times as suggested by the manufacturer. These assumptions may change based on changes in the utilization of aircraft, changes in government regulations and suggested manufacturer maintenance intervals. In addition, these assumptions can be affected by unplanned incidents that could damage an airframe, engine, or major component to a level that would require a heavy maintenance event prior to a scheduled maintenance event. To the extent the planned usage increases, the estimated life would decrease before the next maintenance event, resulting in additional expense over a shorter period. During the years ended December 31, 2017 and 2016, the Company capitalized major maintenance events as part of leasehold improvements to flight equipment for an amount of Ps.529,331 and Ps.226,526, respectively (Note 12). For the years ended December 31, 2017, 2016 and 2015, the amortization of major maintenance leasehold improvement costs was Ps.382,745, Ps.404,659 and Ps.352,932, respectively (Note 12). The amortization of deferred maintenance costs is recorded as part of depreciation and amortization in the consolidated statements of operations. (iii) The Company has a power-by-the hour agreement for component services, which guarantees the availability of aircraft parts for the Company’s fleet when they are required. It also provides aircraft parts that are included in the redelivery conditions of the contract (hard time) without constituting an additional cost at the time of redelivery. The monthly maintenance cost associated with this agreement is recognized as incurred in the consolidated statements of operations. The Company has an engine flight hour agreement that guarantees a cost per overhaul, provides miscellaneous engines coverage, caps the cost of foreign objects damage events, ensures there is protection from annual escalations, and grants an annual credit for scrapped components. The cost associated with the miscellaneous engines coverage is recorded monthly as incurred in the consolidated statements of operations.
Rotable spare parts, furniture and equipment, net | Rotable spare parts, furniture and equipment, net Rotable spare parts, furniture and equipment, are recorded at cost and are depreciated to estimated residual values over their estimated useful lives using the straight-line method. Aircraft spare engines have significant parts with different useful lives; therefore, they are accounted for as separate items (major components) of rotable spare parts (Note 12d). Pre-delivery payments refer to prepayments made to aircraft and engine manufacturers during the manufacturing stage of the aircraft. The borrowing costs related to the acquisition or construction of a qualifying asset are capitalized as part of the cost of that asset. During the years ended December 31, 2017, 2016 and 2015, the Company capitalized borrowing costs which amounted to Ps.193,389, Ps.95,445 and Ps.90,057, respectively (Note 21). The rate used to determine the amount of borrowing cost was 3.30%, 2.88% and 2.80%, for the years ended December 31, 2017, 2016 and 2015, respectively. Depreciation rates are as follows:
|  | Annual depreciation rate |
Aircraft parts and rotable spare parts |  | 8.3-16.7% |
Aircraft spare engines |  | 4.0-8.3% |
Standardization |  | Remaining contractual lease term |
Computer equipment |  | 25% |
Communications equipment |  | 10% |
Office furniture and equipment |  | 10% |
Electric power equipment |  | 10% |
Workshop machinery and equipment |  | 10% |
Service carts on board |  | 20% |
Leasehold improvements to flight equipment |  | The shorter of: (i) remaining contractual lease term, or (ii) the next major maintenance event |
The Company reviews annually the useful lives and salvage values of these assets and any changes are accounted for prospectively. The Company records impairment charges on rotable spare parts, furniture and equipment used in operations when events and circumstances indicate that the assets may be impaired or when the carrying amount of a long-lived asset or related cash generating unit exceeds its recoverable amount, which is the higher of (i) its fair value less cost to sell and (ii) its value in use. The value in use calculation is based on a discounted cash flow model, using projections of operating results for the near future. The recoverable amount of long-lived assets is sensitive to the uncertainties inherent in the preparation of projections and the discount rate used in the calculation. For the years ended December 31, 2017, 2016 and 2015, there were no indicators of impairment. No impairment charges were recorded in respect of the Company’s rotable spare parts, furniture and equipment.
Foreign currency transactions and exchange differences | Foreign currency transactions and exchange differences The Company’s consolidated financial statements are presented in Mexican peso, which is the reporting and functional currency of the parent company. For each subsidiary, the Company determines the functional currency and items included in the financial statements of each entity are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The financial statements of foreign subsidiaries prepared under IFRS and denominated in their respective local currencies, are translated into the functional currency as follows:
| · |  | Transactions in foreign currencies are translated into the respective functional currencies at the exchange rates at the dates of the transactions.
| · |  | All monetary assets and liabilities were translated at the exchange rate at the consolidated statement of financial position date.
| · |  | All non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions.
| · |  | Equity accounts are translated at the prevailing exchange rate at the time the capital contributions were made and the profits were generated.
| · |  | Revenues, costs and expenses are translated at the average exchange rate during the applicable period.
Any differences resulting from the currency translation are recognized in the consolidated statements of operations. For the year ended December 31, 2017 and 2016 the exchange rates of local currencies translated to functional currencies are as follows:
|  |  |  |  |  | Exchange rates of local currencies translated to functional currencies |  | Exchange rates of local currencies translated to functional currencies |
Country |  | Local currency |  | Functional currency |  | Average exchange rate for 2017 |  | Exchange rate as of 2017 |  | Average exchange rate for 2016 |  | Exchange rate as of 2016 |
Costa Rica |  | Colon |  | U.S. dollar |  | ₵. | 572.2000 |  | ₵. | 572.5600 |  | ₵. | 564.3332 |  | ₵. | 561.1000 |
Guatemala |  | Quetzal |  | U.S. dollar |  | Q. | 7.3509 |  | Q. | 7.3448 |  | Q. | 7.4931 |  | Q. | 7.5221 |
The exchange rates used to translate the above amounts to Mexican pesos at December 31, 2017 and 2016 were Ps.19.7354 and Ps.20.6640, respectively, per U.S. dollar. Foreign currency differences arising on translation into the presentation currency are recognized in OCI. Exchange differences on translation of foreign entities for the year ended December 31, 2017 and 2016 were Ps.7,178 and Ps.4,756, respectively. For the year ended December 31, 2015 exchange differences on translation of foreign entities were immaterial
Liabilities and provisions | Liabilities and provisions Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. Where discounting is used, the increase in the provision due to the passage of time is recognized as a finance cost. For the operating leases, the Company is contractually obligated to return the leased aircraft in a specific condition. The Company accrues for restitution costs related to aircraft held under operating leases throughout the term of the lease, based upon the estimated cost of satisfying the return condition criteria for each aircraft. These return obligations are related to the costs to be incurred in the reconfiguration of aircraft (interior and exterior), painting, carpeting and other costs, which are estimated based on current cost adjusted for inflation. The return obligation is estimated at the inception of each leasing arrangement and recognized over the term of the lease (Note 15c). The Company records aircraft lease return obligation reserves based on the best estimate of the return obligation costs under each aircraft lease agreement. The aircraft lease agreements of the Company also require that the aircraft and engines be returned to lessors under specific conditions of maintenance. The costs of return, which in no case are related to scheduled major maintenance, are estimated and recognized ratably as a provision from the time it becomes likely such costs will be incurred and can be estimated reliably. These return costs are recognized on a straight-line basis as a component of supplemental rent and the provision is included as part of other liabilities, through the remaining lease term. The Company estimates the provision related to airframe, engine overhaul and limited life parts using certain assumptions including the projected usage of the aircraft and the expected costs of maintenance tasks to be performed. For the years ended December 31, 2017, 2016 and 2015, the Company expensed as supplemental rent Ps.851,410, Ps.933,730 and Ps.91,698, respectively.
Employee benefits | Employee benefits i) Personnel vacations The Company and its subsidiaries in Mexico and Central America recognize a reserve for the costs of paid absences, such as vacation time, based on the accrual method. ii) Termination benefits The Company recognizes a liability and expense for termination benefits at the earlier of the following dates: a) When it can no longer withdraw the offer of those benefits; and b) When it recognizes costs for a restructuring that is within the scope of IAS 37, Provisions, Contingent Liabilities and Contingent Assets, and involves the payment of termination benefits. The Company is demonstrably committed to a termination when, and only when, it has a detailed formal plan for the termination and is without realistic possibility of withdrawal. For the years ended December 31, 2017, 2016 and 2015, no termination benefits provision has been recognized. iii) Seniority premiums In accordance with Mexican Labor Law, the Company provides seniority premium benefits to the employees who rendered services to its Mexican subsidiaries under certain circumstances. These benefits consist of a one-time payment equivalent to 12 days’ wages for each year of service (at the employee’s most recent salary, but not to exceed twice the legal minimum wage), payable to all employees with 15 or more years of service, as well as to certain employees terminated involuntarily prior to the vesting of their seniority premium benefit. Obligations relating to seniority premiums other than those arising from restructurings, are recognized based upon actuarial calculations and are determined using the projected unit credit method. The latest actuarial computation was prepared as of December 31, 2017. Remeasurement gains and losses are recognized in full in the period in which they occur in OCI. Such remeasurement gains and losses are not reclassified to profit or loss in subsequent periods. The defined benefit asset or liability comprises the present value of the defined benefit obligation using a discount rate based on government bonds (Certificados de la Tesorería de la Federación, or “CETES” in Mexico), less the fair value of plan assets out of which the obligations are to be settled. For entities in Costa Rica and Guatemala there is no obligation to pay seniority premium or other retirement benefits. iv) Incentives The Company has a quarterly incentive plan for certain personnel whereby cash bonuses are awarded for meeting certain performance targets. These incentives are payable shortly after the end of each quarter and are accounted for as a short-term benefit under IAS 19, Employee Benefits. A provision is recognized based on the estimated amount of the incentive payment. During the years ended December 31, 2017, 2016 and 2015 the Company expensed Ps.48,384, Ps.40,829 and Ps.50,558, respectively, as quarterly incentive bonuses, recorded under the caption salaries and benefits. During the year ended December 31, 2015, the Company adopted a new short-term benefit plan for certain key personnel whereby cash bonuses are awarded when certain of the Company’s performance targets are met. These incentives are payable shortly after the end of each year and also are accounted for as a short-term benefit under IAS 19. A provision is recognized based on the estimated amount of the incentive payment. During the years ended December 31, 2017, 2016 and 2015 the Company recorded an expense for an amount of Ps.0, Ps.53,738, and Ps.70,690, respectively, under the caption salaries and benefits. v) Long-term retention plan (“LTRP”) The Company has adopted a Long-term incentive plan (“LTIP”). This plan consists of a share purchase plan (equity-settled) and a share appreciation rights “SARs” plan (cash settled), and is therefore accounted under IFRS 2 “Shared based payments” vi) Share-based payments a) LTIP  Share purchase plan (equity-settled) Certain key employees of the Company receive additional benefits through a share purchase plan denominated in Restricted Stock Units (“RSUs”), which has been classified as an equity-settled share-based payment. The cost of the equity-settled share purchase plan is measured at the grant date, taking into account the terms and conditions on which the share options were granted. The equity-settled compensation cost is recognized in the consolidated statement of operations under the caption of salaries and benefits, over the requisite service period (Note 17). During the years ended December 31, 2017, 2016 and 2015, the Company expensed Ps.13,508, Ps.7,816 and Ps.6,018, respectively, related to RSUs. The expenses were recorded under the caption salaries and benefits.  SARs plan (cash settled) The Company granted SARs to key employees, which entitle them to a cash payment after a service period. The amount of the cash payment is determined based on the increase in the share price of the Company between the grant date and the time of exercise. The liability for the SARs is measured, initially and at the end of each reporting period until settled, at the fair value of the SARs, taking into account the terms and conditions on which the SARs were granted. The compensation cost is recognized in the consolidated statement of operations under the caption of salaries and benefits, over the requisite service period (Note 17). During the years ended December 31, 2017, 2016 and 2015, the Company recorded a (benefit) expense for Ps.(8,999), Ps.31,743, Ps.44,699, respectively, related to the SARs included in the LTIP. These amounts were recorded under the caption salaries and benefits. b) Management incentive plan (“MIP”)  MIP I Certain key employees of the Company receive additional benefits through a share purchase plan, which has been classified as an equity-settled share-based payment. The equity-settled compensation cost is recognized in the consolidated statement of operations under the caption of salaries and benefits, over the requisite service period (Note 17). During the year ended December 31, 2015, the Company recorded an expense by Ps.327 as cost of the MIP, related to the vested shares, the expense was recorded in the consolidated statement of operations under the caption salaries and benefits.  MIP II On February 19, 2016, the Board of Directors of the Company authorized an extension to the MIP for certain key employees, this plan was named MIP II. In accordance with this plan, the Company granted SARs to key employees, which entitle them to a cash payment after a service period. The amount of the cash payment is determined based on the increase in the share price of the Company between the grant date and the time of exercise. The liability for the SARs is measured initially and at the end of each reporting period until settled at the fair value of the SARs, taking into account the terms and conditions on which the SARs were granted. The compensation cost is recognized in the consolidated statement of operations under the caption of salaries and benefits, over the requisite service period (Note 17). During the years ended December 31, 2017 and 2016, the Company recorded a (benefit) expense for Ps.(16,499) and Ps.54,357, respectively, related to MIP II into the consolidated statement of operations. vii) Employee profit sharing The Mexican Income Tax Law (“MITL”), establishes that the base for computing current year employee profit sharing shall be the taxpayer’s taxable income of the year for income tax purposes, including certain adjustments established in the Income Tax Law, at the rate of 10%. For the years ended December 2017, 2016 and 2015, the cost of employee profit sharing earned is Ps.8,342, Ps.9,967 and Ps.9,938, respectively, and is presented as an expense in the consolidated statements of operations. Subsidiaries in Central America do not have such profit sharing benefit, as it is not required by local regulation.
Leases | Leases The determination of whether an arrangement is, or contains a lease, is based on the substance of the arrangement at inception date, whether fulfillment of the arrangement is dependent on the use of a specific asset or assets or the arrangement conveys a right to use the asset, even if that right is not explicitly specified in an arrangement. Property and equipment lease agreements are recognized as finance leases if the risks and benefits incidental to ownership of the leased assets have been transferred to the Company when (i) the ownership of the leased asset is transferred to the Company upon termination of the lease; (ii) the agreement includes an option to purchase the asset at a reduced price; (iii) the term of the lease is for the major part of the economic life of the leased asset; (iv) the present value of minimum lease payments is at least substantially all of the fair value of the leased asset; or (v) the leased asset is of a specialized nature for the Company. When the risks and benefits incidental to the ownership of the leased asset remain mostly with the lessor, they are classified as operating leases and rental payments are charged to results of operations on a straight-line over the term of the lease. The Company’s lease contracts for aircraft, engines and components parts are classified as operating leases. Sale and leaseback The Company enters into sale and leaseback agreements whereby an aircraft or engine is sold to a lessor upon delivery and the lessor agrees to lease such aircraft or engine back to the Company. Leases under sale and leaseback agreements meet the conditions for treatment as operating leases. Profit or loss related to a sale transaction followed by an operating lease, is accounted for as follows:
| (i) |  | Profit or loss is recognized immediately when it is clear that the transaction is established at fair value.
| (ii) |  | If the sale price is at or below fair value, any profit or loss is recognized immediately. However, if the loss is compensated for by future lease payments at below market price, such loss is recognized as an asset in the consolidated statements of financial position and amortized to the consolidated statements of operations in proportion to the lease payments over the contractual lease term.
| (iii) |  | If the sale price is above fair value, the excess of the price above the fair value is deferred and amortized to the consolidated statements of operations over the asset’s expected lease term, including probable renewals, with the amortization recorded as a reduction of rent expense.
Other taxes and fees payable | Other taxes and fees payable The Company is required to collect certain taxes and fees from customers on behalf of government agencies and airports and to remit these to the applicable governmental entity or airport on a periodic basis. These taxes and fees include federal transportation taxes, federal security charges, airport passenger facility charges, and foreign arrival and departure fees. These charges are collected from customers at the time they purchase their tickets, but are not included in passenger revenue. The Company records a liability upon collection from the customer and discharges the liability when payments are remitted to the applicable governmental entity or airport.
Income taxes | Income taxes Current income tax Current income tax assets and liabilities for the current period are measured at the amount expected to be recovered from or paid to the tax authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date. Current income tax relating to items recognized directly in equity is recognized in equity. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate. Deferred tax Deferred tax is provided using the liability method on temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date. Deferred tax liabilities are recognized for all taxable temporary differences, except, in respect of taxable temporary differences associated with investments in subsidiaries when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future. Deferred tax assets are recognized for all deductible temporary differences, the carry-forward of unused tax credits and any available tax losses to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry-forward of unused tax credits and available tax losses can be utilized, except, in respect of deductible temporary differences associated with investments in subsidiaries deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profits will be available against which the temporary differences can be utilized. The Company considers the following criteria in assessing the probability that taxable profit will be available against which the unused tax losses or unused tax credits can be utilized: (a) whether the entity has sufficient taxable temporary differences relating to the same taxation authority and the same taxable entity, which will result in taxable amounts against which the unused tax losses or unused tax credits can be utilized before they expire; (b) whether it is probable that the Company will have taxable profits before the unused tax losses or unused tax credits expire; (c) whether the unused tax losses result from identifiable causes which are unlikely to recur; and (d) whether tax planning opportunities are available to the Company that will create taxable profit in the period in which the unused tax losses or unused tax credits can be utilized. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date. Deferred tax relating to items recognized outside profit or loss is recognized outside profit or loss. Deferred tax items are recognized in correlation to the underlying transaction in OCI. Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority. The charge for income taxes incurred is computed based on tax laws approved in Mexico, Costa Rica and Guatemala at the date of the consolidated statement of financial position.
Derivative financial instruments and hedge accounting | Derivative financial instruments and hedge accounting The Company mitigates certain financial risks, such as volatility in the price of jet fuel, adverse changes in interest rates and exchange rate fluctuations, through a risk management program that includes the use of derivative financial instruments. In accordance with IFRS 9 (2013), derivative financial instruments are recognized in the consolidated statement of financial position at fair value. At inception of a hedge relationship, the Company formally designates and documents the hedge relationship to which it wishes to apply hedge accounting, as well as the risk management objective and strategy for undertaking the hedge. The documentation includes the hedging strategy and objective, identification of the hedging instrument, the hedged item or transaction, the nature of the risks being hedged and how the entity will assess the effectiveness of changes in the hedging instrument’s fair value in offsetting the exposure to changes in the hedged item’s fair value or cash flows attributable to the hedged risk(s). Only if such hedges are expected to be effective in achieving offsetting changes in fair value or cash flows of the hedge item(s) and are assessed on an ongoing basis to determine that they actually have been effective throughout the financial reporting periods for which they were designated, hedge accounting treatment can be used. Under the cash flow hedge (CFH) accounting model, the effective portion of the hedging instrument’s changes in fair value is recognized in OCI, while the ineffective portion is recognized in current year earnings. During the years ended December 31, 2017, 2016 and 2015, there was no ineffectiveness with respect to derivative financial instruments. The amounts recognized in OCI are transferred to earnings in the period in which the hedged transaction affects earnings. The realized gain or loss of derivative financial instruments that qualify as CFH is recorded in the same caption of the hedged item in the consolidated statement of operations. Accounting for the time value of options The Company accounts for the time value of options in accordance with IFRS 9 (2013), which requires all derivative financial instruments to be initially recognized at fair value. Subsequent measurement for options purchased and designated as CFH requires that the option’s changes in fair value be segregated into its intrinsic value (which will be considered the hedging instrument’s effective portion in OCI) and its correspondent changes in extrinsic value (time value and volatility). The extrinsic value changes will be considered as a cost of hedging (recognized in OCI in a separate component of equity) and accounted for in income when the hedged item also is recognized in income.
Financial instruments - Disclosures | Financial instruments — Disclosures IFRS 7 requires a three-level hierarchy for fair value measurement disclosures and requires entities to provide additional disclosures about the relative reliability of fair value measurements (Notes 4 and 5).
Treasury shares | Treasury shares The Company’s equity instruments that are reacquired (treasury shares), are recognized at cost and deducted from equity. No gain or loss is recognized in profit or loss on the purchase, sale, issue or cancellation of treasury shares. Any difference between the carrying amount and the consideration received, if reissued, is recognized in additional paid in capital. Share-based payment options exercised during the reporting period are settled with treasury shares (Note 17).
Operating segments | Operating segments The Company is managed as a single business unit that provides air transportation and related services and accordingly, it has only one operating segment. The Company has two geographic areas identified as domestic (Mexico) and international (United States of America and Central America) (Note 24).
Current versus non-current classification | Current versus non-current classification The Company presents assets and liabilities in the consolidated statement of financial position based on current/non-current classification. An asset is current when it is: (i) expected to be realized or intended to be sold or consumed in normal operating cycle, (ii) expected to be realized within twelve months after the reporting period, or, (iii) cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period. All other assets are classified as non-current. A liability is current when: (i) it is expected to be settled in normal operating cycle, (ii) it is due to be settled within twelve months after the reporting period, or, (iii) there is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period. The Company classifies all other liabilities as non-current. Deferred tax assets and liabilities are classified as noncurrent assets and liabilities.
Impact of new International Financial Reporting Standards | Impact of new International Financial Reporting Standards New and amended standards and interpretations already effective The Company applied for the first time certain standards and amendments, which are effective for annual periods beginning on or after January 1, 2017. The Company has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective. Although these new standards and amendments applied for the first time in 2017, they did not have a material impact on the annual consolidated financial statements of the Company. The nature and the impact of these changes to each new standard and amendment are described below: Amendments to IAS 7 Statement of Cash Flows: Disclosure Initiative The amendments require entities to provide disclosure of changes in their liabilities arising from financing activities, including both changes arising from cash flows and non-cash changes (such as foreign exchange gains or losses). The Company has provided the information for both the current and the comparative period in Note 5. Amendments to IAS 12 Income Taxes: Recognition of Deferred Tax Assets for Unrealized Losses The amendments clarify that an entity needs to consider whether tax law restricts the sources of taxable profits against which it may make deductions on the reversal of deductible temporary difference related to unrealized losses. Furthermore, the amendments provide guidance on how an entity should determine future taxable profits and explain the circumstances in which taxable profit may include the recovery of some assets for more than their carrying amount. However, their application has no effect on the Company’s financial position and performance as there are no deductible temporary differences or assets that are in the scope of the amendments. New and amended standards and interpretations not yet effective Except for IFRS 9 adopted in 2014, the Company has not early adopted any of the following standards, interpretations or amendments that have been issued but is not yet effective. IFRS 9 (2014) Financial Instruments The Company adopted IFRS 9 (2013) in connection with its 2014 consolidated financial statements. IFRS 9 (2014) requires entities to apply an expected credit loss (ECL) model that replaces the IAS 39’s incurred loss model. The ECL model applies to debt instruments accounted for at amortized cost or at fair value through OCI, most loan commitments, financial guarantee contracts, contract assets under IFRS 15 Revenue from Contracts with Customers and lease receivables under IAS 17 Leases or IFRS 16 Leases. IFRS 9 (2014) is effective for annual periods beginning on or after January 1, 2018, and since the Company early adopted IFRS 9 (2013), no additional impact is expected IFRS 15 Revenue from Contracts with Customers IFRS 15 was issued in May 2014 and amended in April 2016, and establishes a five-step model to account for revenue arising from contracts with customers. Under IFRS 15, revenue is recognized at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. The principles in IFRS 15 provide a more structured approach to measuring and recognizing revenue. The new revenue standard will supersede all current revenue recognition requirements under IFRS. IFRS 15 also requires additional disclosures about the nature, timing, and uncertainty of revenue cash flows arising from customer contracts, including significant judgments and changes in judgments. The Company will adopt the new standard on the required effective date as of January 1, 2018, using the full retrospective method of adoption, in order to provide for comparative results in all periods presented, recognizing the effect in retained earnings as of January 1, 2016. During 2016, the Company performed a preliminary assessment of IFRS 15, which was continued with a more detailed analysis completed in 2017. The Company expects that the main impact of IFRS 15 is the timing of recognition of certain air travel-related services (“ancillaries”). Under the current accounting policy, certain ancillaries are recognized as revenue at the time of the booking by customer (or when the service is provided); under the new standard, those ancillaries will be recognized when the air transportation service is rendered (at the time of the flight). This change arises primarily because those ancillaries do not constitute separate performance obligations or represent administrative tasks that do not represent a promised service and therefore should be accounted for together with the air fare as a single performance obligation of providing passenger transportation. Also certain services provided to the Company’s customers that under the new standard qualify as variable considerations that will be recorded as reduction to revenues. The Company considers this accounting change will not have a material impact on its results of operations and financial position. The Company also expects that the classification of certain ancillary fees in the statement of operations, such as advanced seat selection, fees charges for excess baggage, itinerary changes and other air travel-related services, will change upon adoption of IFRS 15 since they are part of the single performance obligation of providing passenger transportation. The Company expects that these revenues currently classified as non-ticket revenues, approximately Ps.5,915,263 in 2017 and Ps.4,758,074 in 2016, will be reclassified to passenger revenues. The Company also evaluated the principal versus agent considerations as it relates to certain non-air travel services arrangements with third party providers. The Company expects that there will be no changes on revenue. The Company has also identified and implemented changes to its accounting policies and practices, systems and controls, as well as designed and implemented specific controls over its evaluation of the impact of the new guidance on the Company, including a calculation of the cumulative effects, disclosure requirements and the collection of relevant data into the reporting process. While the Company is substantially complete with the process of quantifying the impacts from applying the new guidance, final impact assessment will be finalized during the first quarter of 2018. IFRS 16 Leases IFRS 16 was issued in January 2016 and it replaces IAS 17 Leases, IFRIC 4 Determining Whether an Arrangement Contains a Lease, SIC-15 Operating Leases-Incentives and SIC-27 Evaluating the Substance of Transactions Involving the Legal Form of a Lease. IFRS 16 sets out the principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to account for all leases under a single on-balance sheet model similar to the accounting for finance leases under IAS 17. The standard includes two recognition exemptions for lessees — leases of low-value’ assets (e.g., personal computers) and short-term leases (i.e., leases with a lease term of 12 months or less). At the commencement date of a lease, a lessee will recognize a liability to make lease payments (i.e., the lease liability) and an asset representing the right to use the underlying asset during the lease term (i.e., the right-of-use asset). Lessees will be required to separately recognize the interest expense on the lease liability and the depreciation expense on the right-of-use asset. Lessees will be also required to remeasure the lease liability upon the occurrence of certain events (e.g., a change in the lease term, a change in future lease payments resulting from a change in an index or rate used to determine those payments). The lessee will generally recognize the amount of the remeasurement of the lease liability as an adjustment to the right-of-use asset. IFRS 16 also requires lessees to make more extensive disclosures than under IAS 17. IFRS 16 is effective for annual periods beginning on or after January 1, 2019. Early application is permitted, but not before an entity applies IFRS 15. A lessee can choose to apply the standard using either a full retrospective or a modified retrospective approach. The standard’s transition provisions permit certain reliefs. The Company is in process of completing an assessment of the potential impact of adopting IFRS 16. The adoption of this standard will have a significant impact on the accounting for leased aircraft, engines and other lease agreements, requiring the presentation of those leases with durations of greater than twelve months on the consolidated statement of financial position. The Company anticipates adopting the new standard using the full retrospective method, see Note 14 for more information on the Company’s lease agreements. IFRS 2 Classification and Measurement of Share-based Payment Transactions — Amendments to IFRS 2 In June 2016, the IASB issued amendments to IFRS 2 Share-based Payment that address three main areas: the effects of vesting conditions on the measurement of a cash-settled, share-based payment transaction; the classification of a share-based payment transaction with net settlement features for withholding tax obligations; and accounting where a modification to the terms and conditions of a share-based payment transaction changes its classification from cash-settled to equity-settled. On adoption, entities are required to apply the amendments without restating prior periods, but retrospective application is permitted if elected for all three amendments and other criteria are met. The amendments are effective for annual periods beginning on or after January 1, 2018, with early application permitted. The Company does not expect the amendments to have a significant effect on its consolidated financial statements. IFRIC 23 — Uncertainty over Income Tax Treatments IFRIC 23 clarifies the accounting for uncertainties in income taxes, the interpretation is to be applied to the determination of taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates, when there is uncertainty over income tax treatments under IAS 12. An entity has to consider whether it is probable that the relevant authority will accept each tax treatment, or group of tax treatments, that it used or plans to use in its income tax filing; if the entity concludes that it is probable that a particular tax treatment is accepted, the entity has to determine taxable profit (tax loss), tax bases, unused tax losses, unused tax credits or tax rates consistently with the tax treatment included in its income tax filings. IFRIC 23 is effective for annual reporting periods beginning on or after 1 January 2019. Earlier application is permitted. The Company expects to adopt this interpretation at the effective date.
Convenience translation | Convenience translation U.S. dollar amounts at December 31, 2017 shown in the consolidated financial statements have been included solely for the convenience of the reader and are translated from Mexican pesos, using an exchange rate of Ps.19.7354 per U.S. dollar, as reported by the Mexican Central Bank (Banco de México) as the rate for the payment of obligations denominated in foreign currency payable in Mexico in effect on December 31, 2017. Such translation should not be construed as a representation that the peso amounts have been or could be converted into U.S. dollars at this or any other rate. The referred information in U.S. dollars is solely for information purposes and does not represent that the amounts are in accordance with IFRS or the equivalent in U.S. dollars in which the transactions were conducted or in which the amounts presented in Mexican pesos can be translated or realized.
