Companies Act 1985

42 (1) Where the value of any asset of a company is determined in accordance with paragraph 41, that value shall be, or (as the case may require) be the starting point for determining, the amount to be included in respect of that asset in the company’s accounts, instead of its cost or any value previously so determined for that asset; and the depreciation rules shall apply accordingly in relation to any such asset with the substitution for any reference to its cost of a reference to the value most recently determined for that asset in accordance with paragraph 41.

(2) The amount of any provision for depreciation required in the case of any fixed asset by paragraph 25 or 26 as it applies by virtue of sub-paragraph (1) is referred to below in this paragraph as the “adjusted amount”, and the amount of any provision which would be required by that paragraph in the case of that asset according to the historical cost accounting rules is referred to as the “historical cost amount”.

(3) Where sub-paragraph (1) applies in the case of any fixed asset the amount of any provision for depreciation in respect of that asset included in any item shown in the profit and loss account in respect of amounts written off assets of the description in question may be the historical cost amount instead of the adjusted amount, provided that the amount of any difference between the two is shown separately in the profit and loss account or in a note to the accounts.
