i. Foreign currency transactions
Transactions in foreign currencies are translated to the respective functional currencies of the Company at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date are translated to the functional currency at the exchange rate at that date. The foreign currency gain and loss on monetary items is the difference between amortized cost in the functional currency at the beginning of the period, adjusted for interest and principal payments during the period, and the amortized cost in foreign currency translated at the exchange rate at the end of the reporting period.
Non-monetary items that are measured at historical cost in a foreign currency are translated using the exchange rate at the date of the transaction.
ii. Translation of foreign operations
Assets and liabilities, including goodwill and fair value adjustments arising on acquisition, of foreign operations whose functional currency differs from the reporting currency, are translated into Mexican pesos at the exchange rates at the reporting date. Income and expenses are translated to pesos at the average exchange rate of the period of the transactions.
Foreign currency differences associated with translating foreign operations into the reporting currency (Mexican peso) are recognized in other comprehensive income, and presented in the foreign currency translation reserve in stockholders’ equity.
Foreign exchange gains and losses arising from amounts receivable or payable to a foreign operation, whose settlement is neither planned nor likely in the foreseeable future, are considered part of a net investment in a foreign operation and are recognized under the “other comprehensive income” account, and presented within stockholders’ equity in the foreign currency translation reserve. For the years ended December 31, 2017, 2016 and 2015 the Company did not enter into such transactions.
