Another confusing student here. So the clue which tell us what amount should we take in the impairment calculation in Dec 2012 question is “the recoverable amount has been determined without consideration of liabilities ” . Without this note, we should take into consideration when calculating the impairment : nett assets + fair value adjustments +goodwill. In Dec 2012 the equation change because nett assets = total assets – liabilities , which in this case liabilities = 0.
I am understanding the formulas better than the words.
