(1)This section applies if—
(a)on a person ceasing to have a beneficial interest in shares, that person acquires other shares or an interest in other shares, and
(b)the circumstances are such that the shares in which the person ceases to have a beneficial interest constitute “original shares” and the other shares constitute a “new holding” for the purposes of sections 127 to 130 of TCGA 1992 (reorganisations).
(2)Section 127 of TCGA 1992 (under which disposals on reorganisations are disregarded and new holdings are treated as acquired as the original shares were) applies for the purposes of this Chapter.
(3)Any consideration which—
(a)the person gives or becomes liable to give for the new holding, and
(b)is not excluded by virtue of section 128(2) of TCGA 1992 from being consideration for the purposes of section 128(1) of that Act,
is to be treated for the purposes of this Chapter as an increase in the consideration for the original acquisition for the purposes of section 455(2)(a) above (amounts that may be deducted in calculating the amount of the tax charge).
(4)If any consideration of the kind mentioned in section 128(3) of TCGA 1992 is received for the disposal of the original shares—
(a)it is to be apportioned among the shares comprising the new holding, and
(b)the amount which, apart from this subsection, would at a subsequent time be the value of any of those shares is to be treated as being increased by the amount of the consideration apportioned to them.
