An impairment review as at 31st December 2014 shows that the value of goodwill is now 1.5 million less than originally paid. Calculate the value of goodwill to be shown in Bigger's group statement of financial position on 31 December 2014? (Assume no other goodwill apart from that relating to the Smaller subsidiary.)
