The value of one currency for the purpose of one conversion to another. For STR reporting purposes, this is the factor used to convert U.S. dollar revenue to local currency and vice versa. STR obtains exchange rate data from Oanda.com. Monthly data uses the rate on the last day of the respective month. Daily data uses the corresponding daily rate. When calculating STR reporting data, any aggregated number (YTD, Running 3-month or Running 12-month) uses the exchange rate of each relative month. See: Constant Currency.
