(1)This section shall apply where a person acquires an asset and the person making the disposal is connected with him.
(2)Without prejudice to the generality of section 17(1) the person acquiring the asset and the person making the disposal shall be treated as parties to a transaction otherwise than by way of a bargain made at arm’s length.
(3)Subject to subsection (4) below, if on the disposal a loss accrues to the person making the disposal, it shall not be deductible except from a chargeable gain accruing to him on some other disposal of an asset to the person acquiring the asset mentioned in subsection (1) above, being a disposal made at a time when they are connected persons.
(4)Subsection (3) above shall not apply to a disposal by way of gift in settlement if the gift and the income from it is wholly or primarily applicable for educational, cultural or recreational purposes, and the persons benefiting from the application for those purposes are confined to members of an association of persons for whose benefit the gift was made, not being persons all or most of whom are connected persons.
(5)Where the asset mentioned in subsection (1) above is an option to enter into a sale or other transaction given by the person making the disposal a loss accruing to the person acquiring the asset shall not be an allowable loss unless it accrues on a disposal of the option at arm’s length to a person who is not connected with him.
(6)Subject to subsection (7) below, in a case where the asset mentioned in subsection (1) above is subject to any right or restriction enforceable by the person making the disposal, or by a person connected with him, then (where the amount of the consideration for the acquisition is, in accordance with subsection (2) above, deemed to be equal to the market value of the asset) that market value shall be—
(a)what its market value would be if not subject to the right or restriction, minus—
(b)the market value of the right or restriction or the amount by which its extinction would enhance the value of the asset to its owner, whichever is the less.
(7)If the right or restriction is of such a nature that its enforcement would or might effectively destroy or substantially impair the value of the asset without bringing any countervailing advantage either to the person making the disposal or a person connected with him or is an option or other right to acquire the asset or, in the case of incorporeal property, is a right to extinguish the asset in the hands of the person giving the consideration by forfeiture or merger or otherwise, the market value of the asset shall be determined, and the amount of the gain accruing on the disposal shall be computed, as if the right or restriction did not exist.
(8)Subsections (6) and (7) above shall not apply to a right of forfeiture or other right exercisable on breach of a covenant contained in a lease of land or other property, and shall not apply to any right or restriction under a mortgage or other charge.
