Significant Accounting Policies

Our significant accounting policies are detailed in "Note 2: Basis of Presentation, Use of Accounting Estimates and Significant Accounting Policies" of our 2016 Form 10-K. A further explanation of our Foreign Currency accounting policy is discussed below:

Foreign Currency

Our functional currency is the U.S. dollar, however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar. We determine the functional currency of our subsidiaries that exist and operate in different economic and currency environments based on the primary economic environment in which the subsidiary operates, that is, the currency of the environment in which an entity primarily generates and expends cash. Our significant foreign subsidiaries are located in Europe and the U.S. The functional currency of our significant European subsidiaries is the Euro and the functional currency of our significant U.S. subsidiaries is the U.S. dollar.

Assets and liabilities for subsidiaries whose functional currency is not the U.S. dollar are translated into U.S. dollars based on a combination of both current and historical exchange rates, while their revenues earned and expenses incurred are translated into U.S. dollars at average period exchange rates. Translation adjustments are included as ‘Accumulated other comprehensive income (loss)’ (“AOCI”) in the condensed consolidated balance sheets. Gains and losses arising from transactions denominated in a currency different from an entity’s functional currency are included in ‘Foreign exchange and other (losses) gains’ in our condensed consolidated statements of income (loss).
