(1)For the purposes of the Capital Gains Tax Act 1979 (in this section referred to as " the principal Act"), in any case where,—
(a)by way of two or more material transactions which are linked (in this section referred to as a series of linked transactions), one person disposes of assets to another person with whom he is connected or to two or more other persons with each of whom he is connected, and
(b)the original market value of the assets disposed of by any of the transactions in the series, as determined under Schedule 21 to this Act, is less than the appropriate portion of the aggregate market value of the assets disposed of by all the transactions in the series, as so determined,
then, subject to subsection (2) below, the disposal effected by any linked transaction in the series in respect of which the condition in paragraph (b) above is fulfilled shall be deemed to be for a consideration equal to the appropriate portion referred to in that paragraph.
(2)Where the disposal effected by a material transaction is one to which section 44 of the principal Act applies (disposals of assets between husband and wife) nothing in subsection (1) above shall affect the amount which, for the purposes of the principal Act, is the consideration for that disposal.
(3)Subject to subsections (6) to (8) below, any reference in this section to a material transaction is a reference to a transaction by way of gift or otherwise which takes place after 19th March 1985 ; and for the purposes of this section two or more material transactions are linked if they occur within the period of six years ending on the date of the last of them.
(4)This section shall apply or, as the case may be, shall again apply—
(a)when a second material transaction causes a series of linked transactions to come into being ; and
(b)whenever, on the occurrence of a further material transaction, an existing series is extended by the inclusion of that transaction (whether or not an earlier transaction ceases to form part of the series);
and all such assessments and adjustments of assessments shall be made as may be necessary to give effect to this section on each such occasion.
(5)In consequence of the preceding provisions of this section, any gift or other transaction which occurs after 19th March 1985 shall be disregarded for the purposes of section 151 of the principal Act (the previous code for assets disposed of in a series of transactions).
(6)Where a member of a group of companies disposes of an asset to another member of the group in circumstances such that, by virtue of section 273 of the Taxes Act, both companies are treated, so far as relates to corporation tax on chargeable gains, as if the consideration for the disposal were of such an amount as would secure that neither a gain nor a loss would accrue, the transaction by which that disposal is effected is not a material transaction; and a disposal in these circumstances is in this section referred to as an " inter-group transfer ".
(7)In any case where—
(a)a company (in this subsection referred to as " company A ") disposes of an asset by way of a material transaction, and
(b)company A acquired the asset after 19th March 1985 by way of an inter-group transfer, and
(c)the disposal by company A is to a person who is connected with another company (in this subsection referred to as " company B ") which at some time after 19th March 1985 disposed of the asset by way of an inter-group transfer, and
(d)either the disposal by way of inter-group transfer which is referred to in paragraph (c) above was the occasion of the acquisition referred to in paragraph (b) above or, between that disposal and that acquisition, there has been no disposal of the asset which was not an inter-group transfer,
then, for the purpose of determining whether subsection (1) above applies in relation to a series of linked transactions, the disposal by company A shall be treated as having been made by company B; but any increase in the consideration for that disposal resulting from the application of subsection (1) above shall have effect with respect to company A.
(8)In any case where one or more transactions occur on or before 19th March 1985 and one or more transactions occur after that date in circumstances such that—
(a)if all the transactions had occurred before that date, section 151 of the principal Act would have applied in relation to them, and
(b)if all the transactions occurred after that date, subsection (1) above would apply to them,
such of the transactions which occurred on or before that date as occurred not more than two years before the first of the transactions occurring after that date shall be treated as material transactions.
