This section applies where—
a particular disposal is made as mentioned in section 169VC(1)(a) ("the current disposal"),
there have been one or more previous disposals of shares from the holding mentioned in section 169VC(1) before the current disposal, and
it is necessary to determine for the purposes of this Chapter which shares are to be treated as in the holding immediately before the current disposal (and, accordingly, which shares are to be treated as having been disposed of in those previous disposals).
In the case of a previous disposal as regards which investors' relief has been claimed or is being claimed, the shares to be treated as disposed of in that previous disposal are to be determined in accordance with the rules in section 169VF.
In the case of a previous disposal not falling within subsection (2), the shares to be treated as disposed of in that previous disposal are to be determined in accordance with the rules in section 169VG.
