1 If an amount is received 25/1/2018 for a receivable on the SOFP as at 31/12/2017, it is,evidence that the receivable existed and was properly valued at 31/12/2017
2 If an amount is paid on, say, 10/1/2017 we have to decide whether it relates to an expense for 2017 (in which case it should be accrued on the SOFP of 31/12/2017) or whether it is a 2018 expense.
