CG52020 | Reorganisations of share capital: apportionment of cost where ‘relevant securities’ involved
From HM Revenue & Customs · Capital Gains Manual
The ordinary share pooling and identification rules do not apply to ‘relevant securities’, as that term is defined at TCGA92/S108. This is because the rules relating to relevant securities require the identification of individual securities and this would not be possible if they had lost their identity in a Section 104 pool. For further guidance on relevant securities see CG51650.
It is possible that a share reorganisation may involve an issue of relevant securities in respect of shares in a Section 104 pool. For example, a company may make a rights issue of debentures within the Accrued Income Scheme. In such cases you will need to establish
the date the relevant securities were acquired and
the acquisition cost of the relevant securities unless the Section 104 holding has been replaced by the securities, for example, on a takeover.
You should apportion the pool of qualifying expenditure between the new holding and the relevant securities in the same way that you apportion costs in a share reorganisation involving quoted shares. This means using the formula in TCGA92/S130. The apportionment is made by reference to market value at the date of the reorganisation. The instructions on Section 130 are at CG51965+ and there is an example of a computation at CG51981.
