31/12/x2———500——————1/1.1————455
31/x2/x3——–(10000+500)——-1/1.1^2——–8678
===================================9133
the fv of financial liability is 9.13

dr FL—(10000-9133)-867
cr p/l–867

my question here is that since the C/F on 31 december 20×1 is 10500 why we deduct 9133 from 10000 not 10500?when we debit p/l is it again impairment or loss allowance?
