2(1)Subject to paragraph 4 below and section 109(4), paragraph 1(2) above shall not apply in relation to a disposal of assets—
(a)if on the assumption in paragraph 1(2) a gain would accrue on that disposal to the person making the disposal and either a smaller gain or a loss would so accrue if paragraph 1(2) did not apply, or
(b)if on the assumption in paragraph 1(2) a loss would so accrue and either a smaller loss or a gain would accrue if paragraph 1(2) did not apply,
and accordingly the amount of the gain or loss accruing on the disposal shall be computed without regard to the preceding provisions of this Schedule except that in a case where this sub-paragraph would otherwise substitute a loss for a gain or a gain for a loss it shall be assumed, in relation to the disposal, that the relevant assets were sold by the owner, and immediately reacquired by him, for a consideration such that, on the disposal, neither a gain nor a loss accrued to the person making the disposal.
(2)For the purpose of—
(a)identifying shares or securities held on 6th April 1965 with shares or securities previously acquired, and
(b)identifying the shares or securities held on that date with shares or securities subsequently disposed of, and distinguishing them from shares or securities acquired subsequently,
so far as that identification is needed for the purposes of sub-paragraph (1) above, and so far as the shares or securities are of the same class, shares or securities acquired at a later time shall be deemed to be disposed of before shares or securities acquired at an earlier time.
(3)Sub-paragraph (2) above has effect subject to section 105.
