Holderness Ltd prepares its final accounts to 31 December. The company bought a building on 1 January 20X7 for £520,000. Its depreciation policy on buildings has always been to depreciate at 5% p.a. on a straight line basis, but no depreciation is charged in the year of a disposal.

When preparing the Final Accounts for the year ended 31 December 20X8, before any depreciation had been charged for that year, it was decided to revalue the build¬ ing to its estimated replacement cost of £800,000. On 1 September 20X9, the company sold the building for £750,000.
