(1) If, because of the application event:
(a) there is under section 719- 305 an * available fraction for the * bundle of prior group losses; and
(b) section 719- 310 affects the available fraction for one or more other bundles of losses;
this section affects the available fraction for every one of those bundles.
(2) The available fraction (as affected by section 719- 305 or 719- 310) is reduced by multiplying it by this fraction:
(3) For the purposes of working out the fraction in subsection (2), use the value of an * available fraction for a * bundle of losses apart from:
(a) this section; and
(b) if item 5 of the table in subsection 707-320(2) would apply as a result of the calculation of the available fraction in accordance with section 719- 305 or 719- 310--that item.
