24Disposals where assets lost or destroyed, or become of negligible value
(1)Subject to the provisions of this Act and, in particular to section 144, the occasion of the entire loss, destruction, dissipation or extinction of an asset shall, for the purposes of this Act, constitute a disposal of the asset whether or not any capital sum by way of compensation or otherwise is received in respect of the destruction, dissipation or extinction of the asset.
(2)If, on a claim by the owner of an asset, the inspector is satisfied that the value of an asset has become negligible, he may allow the claim and thereupon this Act shall have effect as if the claimant had sold, and immediately reacquired, the asset for a consideration of an amount equal to the value specified in the claim.
(3)For the purposes of subsections (1) and (2) above, a building and any permanent or semi-permanent structure in the nature of a building may be regarded as an asset separate from the land on which it is situated, but where either of those subsections applies in accordance with this subsection, the person deemed to make the disposal of the building or structure shall be treated as if he had also sold, and immediately reacquired, the site of the building or structure (including in the site any land occupied for purposes ancillary to the use of the building or structure) for a consideration equal to its market value at that time.
