On 1 January Year 1 Entity Q purchased for GH$240.000 a machine with an

estimated useful life of 20 years and an estimated zero residual value.

Depreciation is on a straight-line basis.

The asset had been re-valued on 1 January Year 3 to GH$250,000, but with

no change in useful life at that date.

On 1 January Year 4 an impairment review showed the machine's

recoverable amount to be GH$100,000 and its remaining useful life to be

10 years.

Calculate:

a)

The carrying amount of the machine on 31 December Year 2 and

hence the revaluation surplus arising on 1 January Year 3.

b)

The carrying amount of the machine on 31 December Year

3

(immediately before the impairment).

C)

The impairment loss recognised in the year to 31 December Year 4.

d) The depreciation charge in the year to 31 December Year 4.
