For the purposes of section 179(1)(b) above, if—
the price for which those investments were sold or, as the case may be, the best consideration referred to in section 179(1)(b) shall be taken to be increased by an amount equal to the capital payment or, as the case may be, the aggregate of the capital payments, referred to in paragraph (a) above.
If the appropriate person receives or becomes entitled to receive in respect of any qualifying investments a provisional allotment of shares in or debentures of a company and he disposes of his rights, the amount of the consideration for the disposal shall be treated for the purposes of this section as a capital payment attributable to those investments.
In this section "capital payment", in relation to any investment, does not include the price paid on the sale of the investment but, subject to that, includes any money or money's worth which does not constitute income for the purposes of income tax.
