Notes to Consolidated Financial Statements continued Thousands of Georgian Lari 3. Summary of Significant Accounting Policies continued Functional, reporting currencies and foreign currency translation The consolidated financial statements are presented in Georgian Lari, which is the Group’s presentation currency. BOGG’s and the Bank’s functional currency is Georgian Lari. Each entity in the Group determines its own functional currency and items included in the financial statements of each entity are measured using that functional currency. Transactions in foreign currencies are initially recorded in the functional currency, converted at the rate of exchange ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated into functional currency at functional currency rate of exchange ruling at the reporting date. Gains and losses resulting from the translation of foreign currency transactions are recognised in the consolidated income statement as gains less losses from foreign currencies – translation differences. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates as at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. When a gain or loss on a non-monetary item is recognised in other comprehensive income, any exchange component of that gain or loss is recognised in other comprehensive income. Conversely, when a gain or loss on a non-monetary item is recognised in profit or loss, any exchange component of that gain or loss is recognised in the income statement. Differences between the contractual exchange rate of a certain transaction and the NBG exchange rate on the date of the transaction are included in gains less losses from foreign currencies (dealing). The official NBG exchange rates at 31 December 2018, 31 December 2017 and 31 December 2016 were: Lari to GBPLari to US$Lari to EURLari to BYN 31 December 2018 3.3955 2.6766 3.0701 1.2418 31 December 2017 3.5005 2.5922 3.1044 1.3083 31 December 2016 3.2579 2.6468 2.7940 1.3532 As at the reporting date, the assets and liabilities of the entities whose functional currency is different from the presentation currency of the Group are translated into Georgian Lari at the rate of exchange ruling at the reporting date and their income statements are translated at the weighted average exchange rates for the year. The exchange differences arising on the translation are taken to other comprehensive income. On disposal of a subsidiary or an associate whose functional currency is different from the presentation currency of the Group, the deferred cumulative amount recognised in other comprehensive income relating to that particular entity is recognised in the consolidated income statement. Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition are treated as assets and liabilities of the foreign operations and translated at the rate at the reporting date. 200 Annual Report 2018Bank of Georgia Group PLC
