3(1)Subject to sub-paragraph (2) and paragraph 14(1) below, in this Schedule “relevant discounted security” means any security which (whenever issued) is such that—
(a)taking the security as at the time of its issue, and
(b)assuming redemption in accordance with its terms,
the amount payable on redemption is an amount involving a deep gain or might be an amount which would involve such a gain.
(2)The following are not relevant discounted securities for the purposes of this Schedule—
(a)shares in a company;
(b)gilt-edged securities that are not strips;
(c)excluded indexed securities;
(d)life assurance policies;
(e)capital redemption policies (within the meaning of Chapter II of Part XIII of the Taxes Act 1988); and
(f)subject to paragraph 10 below, securities issued (at whatever time) under the same prospectus as other securities which have been issued previously but (disregarding that paragraph) are not themselves relevant discounted securities.
(3)For the purposes of this Schedule the amount payable on redemption of a security involves a deep gain if—
(a)the issue price is less than the amount so payable; and
(b)the amount by which it is less represents more than the relevant percentage of the amount so payable.
(4)In this paragraph “the relevant percentage”, in relation to the amount payable on redemption of a security, means—
(a)the percentage figure equal, in a case where the period between the date of issue and the date of redemption is less than thirty years, to one half of the number of years between those dates; and
(b)in any other case, 15 per cent.;
and for the purposes of this paragraph the fraction of a year to be used for the purposes of paragraph (a) above in a case where the period mentioned in that paragraph is not a number of complete years shall be calculated by treating each complete month, and any remaining part of a month, in that period as one twelfth of a year.
(5)References in this paragraph to redemption—
(a)do not include references to any redemption which may be made before maturity otherwise than at the option of the holder of the security; but
(b)in the case of a security that is capable of redemption at the option of the holder before maturity, shall have effect as references to the earliest occasion on which the holder of the security may require the security to be redeemed.
(6)For the purposes of this paragraph the amount payable on redemption shall not be taken to include any amount payable on that occasion by way of interest.
