90Transfers between settlements
(1)If in a year of assessment for which section 87 or 89(2) applies to a settlement (“the transferor settlement”) the trustees transfer all or part of the settled property to the trustees of another settlement (“the transferee settlement”) then, subject to the following provisions—
(a)if section 87 applies to the transferee settlement for the year, its trust gains for the year shall be treated as increased by an amount equal to the outstanding trust gains for the year of the transferor settlement or, where part only of the settled property is transferred, to a proportionate part of those trust gains;
(b)if subsection (2) of section 89 applies to the transferee settlement for the year (otherwise than by virtue of paragraph (c) below), the trust gains referred to in that subsection shall be treated as increased by the amount mentioned in paragraph (a) above;
(c)if (apart from this paragraph) neither section 87 nor section 89(2) applies to the transferee settlement for the year, subsection (2) of section 89 shall apply to it as if the year were the first year of a resident period succeeding a non-resident period and the trust gains referred to in that subsection were equal to the amount mentioned in paragraph (a) above.
(2)Subject to subsection (3) below, the reference in subsection (1)(a) above to the outstanding trust gains for the year of the transferor settlement is a reference to the amount of its trust gains for the year so far as they are not treated under section 87(4) as chargeable gains accruing to beneficiaries in that year.
(3)Where section 89(2) applies to the transferor settlement for the year, the reference in subsection (1)(a) above to the outstanding trust gains of the settlement is a reference to the trust gains referred to in section 89(2) so far as not treated as chargeable gains accruing to beneficiaries in that or an earlier year.
(4)This section shall not apply to a transfer so far as it is made for consideration in money or money’s worth.
