A suggestion on this one, just to add to the transparency/ease of quickly looking at column III, would be to convert all of this to the same currency. Either:
better way in my eyes: we have all costs listed as how much they were when they hit the bank account in question, or
we decide on one currency and just convert everything.
The most accurate way would be to take the price paid on the day, work out what bundle of goods that buys in the country in question and adjust it based upon these changes up until the point where it needs paying back, at which point we would use an agreed-upon rate…
I joke. It fluctuated a decent amount for sure, but maybe the easiest is just to convert those USD to EUR, late 2021 it was 1.1+, now it’s 0.9/1 but either way it doesn’t require the reader to mentally adjust.
