47Spreading of gains and losses under section 46
(1)Any chargeable gains or allowable losses which would otherwise accrue on disposals deemed by virtue of section 46 above to have been made at the end of a company’s accounting period shall be treated as not accruing to it, but instead—
(a)there shall be ascertained the difference (“the net amount”) between the aggregate of those gains and the aggregate of those losses, and
(b)one seventh of the net amount shall be treated as a chargeable gain or, where it represents an excess of losses over gains, as an allowable loss accruing to the company at the end of the accounting period, and
(c)a further one seventh shall be treated as a chargeable gain or, as the case may be, as an allowable loss accruing at the end of each succeeding accounting period until the whole amount has been accounted for.
(2)For any accounting period of less than one year, the fraction of one seventh referred to in subsection (1)(c) above shall be proportionately reduced; and where this subsection has had effect in relation to any accounting period before the last for which subsection (1)(c) above applies, the fraction treated as accruing at the end of that last accounting period shall also be adjusted appropriately.
(3)Where—
(a)the net amount for an accounting period of an insurance company represents an excess of gains over losses,
(b)the net amount for one of the next six accounting periods (after taking account of any reductions made by virtue of this subsection) represents an excess of losses over gains,
(c)there is (after taking account of any such reductions) no net amount for any intervening accounting period, and
(d)within two years after the end of the later accounting period the company makes a claim for the purpose in respect of the whole or part of the net amount for that period,
the net amounts for both the earlier and the later period shall be reduced by the amount in respect of which the claim is made.
(4)Subject to subsection (5) below, where a company ceases to carry on long term business before the end of the last of the accounting periods for which subsection (1)(c) above would apply in relation to a net amount, the fraction of that amount that is treated as accruing at the end of the accounting period ending with the cessation shall be such as to secure that the whole of the net amount has been accounted for.
(5)Where there is a transfer of the whole or part of the long term business of an insurance company (“the transferor”) to another company (“the transferee”) in accordance with a scheme sanctioned by a court under section 49 of the [1982 c. 50.] Insurance Companies Act 1982, any chargeable gain or allowable loss which (assuming that the transferor had continued to carry on the business transferred) would have accrued to the transferor by virtue of subsection (1) above after the transfer shall instead be deemed to accrue to the transferee.
(6)Where subsection (5) above has effect, the amount of the gain or loss accruing at the end of the first accounting period of the transferee ending after the day when the transfer takes place shall be calculated as if that accounting period began with the day after the transfer.
(7)Where the transfer is of part only of the transferor’s long term business, subsection (5) above shall apply only to such part of any amount to which it would otherwise apply as is appropriate.
(8)Any question arising as to the operation of subsection (7) above shall be determined by the Special Commissioners who shall determine the question in the same manner as they determine appeals; but both the transferor and transferee shall be entitled to appear and be heard or to make representations in writing.
