Investment bond arrangements are securities for the purposes of this Act and any other enactment about capital gains tax.
For those purposes—
a reference in an enactment to redemption is to be taken as a reference to making the redemption payment, and
a reference in an enactment to interest is to be taken as a reference to alternative finance return.
In subsection (2) "the redemption payment" has the same meaning as in section 151N (see subsection (1)(d)(ii) of that section).
