Janssen translates the financial statements of Triofind-A as of 31 July 2017 and must determine the appropriate value for the warehouse in Triofind's presentation currency. She observes that the cumulative Abuelio inflation rate exceeded 100% from 2015 to 2017. Spot exchange rates and inflation data are presented in Exhibit 3.
