Foreign currencies
The individual financial statements of Scorpio Tankers Inc. and each of its subsidiaries are presented in the currency of the primary economic environment in which we operate (its functional currency), which in all cases is U.S. dollars. For the purpose of the consolidated financial statements, our results and financial position are also expressed in U.S. dollars.
In preparing the financial statements of Scorpio Tankers Inc. and each of its subsidiaries, transactions in currencies other than the U.S. dollar are recorded at the rate of exchange prevailing on the dates of the transactions. At the end of each reporting period, monetary assets and liabilities denominated in other currencies are retranslated into the functional currency at rates ruling at that date. All resultant exchange differences have been recognized in the consolidated statements of income or loss. The amounts charged to the consolidated statements of income or loss during the years ended December 31, 2017, 2016 and 2015 were not material.
