Answer:
10% foreign exchange loss on the U.S. dollar accounts receivable
Step-by-step explanation:
Based on the information provided within the question it can be said that in this example the Canadian subsidiary will record a 10% foreign exchange loss on the U.S. dollar accounts receivable. That is because as the Canadian dollar has appreciated 10% against the U.S. dollar, it means that it has lost 10% of it's buying power due to its foreign exchange price change, thus resulting in a loss which needs to be recorded.
