(b)other than by virtue of section 212, disposes of some or all of those units during the period of three years after the end of the accounting period of the company in which the acquisition took place,
the fraction of any net amount that is treated as accruing at the end of the accounting period of the company in which the disposal occurs is to be adjusted so as to secure that the whole of the chargeable gain or allowable loss attributable to the units disposed of which has been taken into account in determining the net amount has been accounted for; and fractions of the net amount treated as accruing at the end of subsequent accounting periods are to be adjusted accordingly.
(4ZC) For the purposes of subsection (4ZB) (notwithstanding the provisions of Chapter 1 of Part 4 (shares, securities, options etc))—
(a)units in a collective investment scheme acquired as mentioned in subsection (4ZB)(a) are treated as being disposed of before other units in the scheme or, where there are different classes of unit in the scheme, units of the same class held by the company, and
(b)where units are acquired as mentioned in subsection (4ZB)(a) at different times, units acquired at a later time are treated as disposed of before units acquired at an earlier time or, where there are different classes of unit in the scheme, units of the same class acquired at an earlier time.
(4ZD) In subsections (4ZB) and (4ZC), in relation to a relevant offshore fund, “units” means rights in the fund which are treated as shares under section 103A (application of Act to certain offshore funds).
(4ZE) In subsection (4ZD), “relevant offshore fund” has the same meaning as in section 103A.”
