Does anyone know how NS calculate the net present value of the lease liability in Lease records? I'm trying to recalculate it via the XNPV function on Excel and they don't arrive at the same value. Maybe NS considers every period 1 full period even if the lease starts in the middle of the month? Also, it does recognize interest on the first payment even if the lease start date is the same with the first payment date. It seems to be a limitation but is there a workaround?
