Hi sir, Does goodwill impairment loss affect GW on acquisition date? From DEC 2 011 to JUNE 2015, it appears that there is no impact , but BEFORE JUNE 2010 , it appears that there is an impact-GW impairment loss has been deducted from GW on acquisition date. I just wonder the reason why, is it because IAS has changed from DEC 2010? Thanks in advance.
