Factors 1 and 2 (dealing with revenues and sales prices) rank higher than Factors 3 and 4. Someone saw this somewhere?

Just did a mock question 20 PM session 2016. It states that something like below. Is this something we need to memorize? Thanks! . Even though Tagus incurs most costs and its financing (long-term debt) in EUR, under IFRS, Factors 1 and 2 (dealing with revenues and sales prices) rank higher than Factors 3 and 4 (dealing with operating and financing costs) when determining functional currency

yes , in CFAI mock, wtf

Makes sense.
