(1) This section applies if:
(a) the leaving entity held assets at the time it became a * subsidiary member of the old group (disregarding subsection 701 - 1(1) (the single entity rule)); and
(b) some or all of the assets:
(i) stopped being * pre - CGT assets under Division 149 at a time (the Division 149 time ) when the * head company of the group held them under subsection 701 - 1(1) (the single entity rule); or
(ii) would have stopped being pre - CGT assets under Division 149 at a time (also the Division 149 time ) when the head company of the group held them under subsection 701 - 1(1) (the single entity rule) if they had been pre - CGT assets just before that time; and
(c) the leaving entity was a subsidiary member of the group at that time.
(2) The * pre - CGT proportion of the leaving entity at the leaving time is taken to be nil.
(3) Adjust the old group's * allocable cost amount for the leaving entity as follows:
(a) if the amount under subsection (4) exceeds the amount under subsection (6)--increase the allocable cost amount by the excess;
(b) if the amount under subsection (4) falls short of the amount under subsection (6)--reduce the allocable cost amount by the shortfall.
(4) Subject to subsection (5), the amount under this subsection is:
(a) if Subdivision 705 - A applied in relation to the leaving entity at the time it became a * subsidiary member of the old group--the total of the amounts that were taken into account under subsection 705 - 65(1) for * membership interests in the leaving entity at that time; or
(b) otherwise--assuming that Subdivision 705 - A had applied in relation to the leaving entity at the time it became a subsidiary member of the old group, the total of the amounts that would have been taken into account under subsection 705 - 65(1) for membership interests in the leaving entity at that time.
(5) For the purposes of subsection (4), if a * membership interest in the leaving entity was covered under paragraph 705 - 125(2)(a) (pre - CGT interests) when it became a * subsidiary member of the old group, treat the amount that was taken into account for the membership interest under subsection 705 - 65(1) as the interest's * market value just after the Division 149 time.
(6) The amount under this subsection is the old group's * allocable cost amount for the leaving entity, worked out on the assumption that the leaving entity ceased to be a * subsidiary member of the old group just after the Division 149 time.
