768. Realised losses and profits and revaluation of fixed assets

(1) The following provisions have effect for the purposes of this Part.
(2) Realised losses include provisions of any kind (except revaluation provisions).
(3) A "revaluation provision" means a provision in respect of a diminution in value of a fixed asset appearing on a revaluation of all the fixed assets of the company, or of all of its fixed assets other than goodwill.
(4) For the purpose of subsections (2) and (3) any consideration by the directors of the value at a particular time of a fixed asset is treated as a revaluation provided—
(a) the directors are satisfied that the aggregate value at that time of the fixed assets of the company that have not actually been revalued is not less than the aggregate amount at which they are then stated in the company's accounts, and
(b) it is stated in a note to the accounts—
(i) that the directors have considered the value of some or all of the fixed assets of the company without actually revaluing them,
(ii) that they are satisfied that the aggregate value of those assets at the time of their consideration was not less than the aggregate amount at which they were then stated in the company's accounts, and
(iii) that accordingly, by virtue of this subsection, amounts are stated in the accounts on the basis that a revaluation of fixed assets of the company is treated as having taken place at that time.
(5) Where—
(a) on the revaluation of a fixed asset, an unrealised profit is shown to have been made, and
(b) on or after the revaluation, a sum is written off or retained for depreciation of that asset over a period,
an amount equal to the amount by which that sum exceeds the sum which would have been so written off or retained for the depreciation of that asset over that period, if that profit had not been made, is treated as a realised profit made over that period.
