If the exchange rate at the end of the a foreign subsidiary's first year was 5 Fidgets to 1 Canadian dollar, and if it was 8 Fidgets to 1 Canadian dollar at the end of the second (current) year, what exchange rate should be used to convert total assets if we want to calculate the company's ROI in Canadian dollars?

A.the average rate for the year, assuming that the rate changed approximately evenly throughout the year

B.the rate in effect when the assets were acquired (ie. 5 to 1)

C.the rate estimated to be in effect when the ROI is to be reported in the financial statements

D.it would be doublecounting to convert the assets leave both assets and income in fidgets and the exchange rate for the numerator cancels out the exchange rate for the denominator

E.the rate in effect when the ROI is calculated
