b) Anaya purchased a non-current asset on 1 January 1991 at a cost of $40,000. At that date, the asset had an estimated useful life of ten years. Anaya does not revalue this type of asset, but accounts for it on the basis of depreciated historical cost. At 31 December 1992, the asset was subject to an impairment review and had a recoverable amount of $16,000. At 31 December 1995, the circumstances which caused the original impairment to be recognised have reversed and are no longer applicable, with the result that the recoverable amount is now $50,000. Required: Explain, with supporting computations, the impact on the financial statements of the two impairment reviews (5 marks)
