(1) If:
(a) the * realisation event mentioned in paragraph 727 - 850(1)(c) is a * CGT event; and
(b) section 727 - 850 reduces a loss that would, apart from this Division, be * realised for income tax purposes by the CGT event; and
(c) there is a roll - over for the CGT event;
the interest's * reduced cost base at the time of the CGT event is taken to have been reduced by the amount by which section 727 - 850 reduces that loss, but is so taken only for the purposes of working out:
(d) the interest's reduced cost base, from time to time after the roll - over, for the entity that * acquired the interest because of the CGT event; and
(e) in the case of a * replacement - asset roll - over--the reduced cost base of the replacement CGT asset, from time to time after the roll - over, for the entity that * disposed of the interest.
Note: Because of the roll - over, the loss reduction under section 727 - 850 will have no tax effect. This subsection ensures that the loss reduction is passed on, through the reduction in reduced cost base, to prevent or reduce a loss arising on a later CGT event.
