Kang, Inc., has a wholly owned subsidiary in Canada that previously had been determined as having the Canadian dollar as its functional currency. Due to a recent restructuring, Kang, Inc.’s CFO believes that the functional currency of the Canadian company has changed to the U.S. dollar. A large cumulative translation adjustment related to the Canadian subsidiary is included in accumulated other comprehensive income on Kang, Inc.’s balance sheet. The CFO is unsure whether the cumulative translation adjustment should be removed from equity, and if so, to what other account it should be transferred. He also questions whether the change in functional currency qualifies as a change in accounting principle, which would require retrospective application of the temporal method in translating the Canadian subsidiary’s financial statements. He wonders, for example, whether the Canadian subsidiary’s nonmonetary assets need to be restated as if the temporal method had been applied in previous years.
