Multicurrency: Exchange Rate Expiration
Currency expiration dates are considered in the context of the “as of” date of the rate. For example, you view the giving history for Robert Hernandez and a gift was given on June 19, 2015 for 50 GBP. You then select to view the giving history in “My Base” which is USD. The application finds the most recent rate between GBP and USD based on June 19, 2015. For this example, it is a corporate rate that expired on June 30, 2015; however, this rate is still good for this conversion because the rate had not expired on the “as of” date of June 19.
When importing exchange rates, the application stores the expiration date on each exchange rate. If the settings change at a later date, those settings apply to future imported exchange rates. Existing rates remain unchanged by the import.
