18  Indexation factor
 (1) For the purposes of this Act, the indexation factor for a financial year is the number calculated, to 3 decimal places (rounding up if the fourth decimal place is 5 or more), using the formula:
where:
base March quarter means the last March quarter before the reference March quarter.
reference March quarter means the last March quarter before the financial year.
 (2) Subject to subsection (3), if (whether before or after the commencement of this section) the Australian Statistician has published or publishes an index number in respect of a quarter in substitution for an index number previously published in respect of that quarter, the publication of the later index number must be disregarded for the purposes of this section.
 (3) If (whether before or after the commencement of this section) the Australian Statistician has changed or changes the index reference period for the Consumer Price Index, then, for the purposes of the application of this section after the change took place or takes place, regard must only be had to the index number published in terms of the new index reference period.
