(1) This section applies where before the end of the relevant period for a qualifying investment, a qualifying company disposes of a qualifying subsidiary (including on a winding up or dissolution referred to in section 492(3)), where the amounts raised from the qualifying investment were, in accordance with section 490(4)(b), invested in eligible shares of that qualifying subsidiary, and the amounts raised from that disposal were not returned to the qualifying investors without undue delay.

(2) For the purposes of section 508M, the qualifying investors who made the qualifying investment that was so employed, shall be treated as if, on the date of that disposal, they partially disposed of the shares that they hold in the qualifying company for an amount equal to the portion (attributable to their shareholding in respect of their eligible shares) of the market value of the qualifying subsidiary on the date it is disposed of, or the amount for which it was disposed if higher.
