58AA  ATI indexation factor for determinations under section 58
 (1) The ATI indexation factor is:
where:
AWE amount for a September quarter of a year of income means the amount published for the reference period in the quarter by the Australian Statistician in a document titled "Average Weekly Earnings, Australia" (or, if that title changes, in a replacement document) under the headings "Average Weekly Earnings—Trend—Persons—All employees total earnings" (or, if any of those headings change, under any replacement headings).
reference period in a September quarter of a year of income means the period described by the Australian Statistician as the last pay period ending on or before the third Friday of the middle month of the quarter.
September quarter of a year of income means the quarter ending on 30 September of that year.
tax return year means:
 (a) if subsection 58(3) applies—the year of income before the last relevant year of income in relation to a child support period; or
 (b) if subsection 58(4) applies—the earlier year of income that applies under paragraph 58(4)(c).
 (2) The ATI indexation factor is to be calculated to 3 decimal places (rounding up if the fourth decimal place is 5 or more).
 (3) If:
 (a) the Australian Statistician publishes an AWE amount (the later amount) for a September quarter of a year of income; and
 (b) the later amount is published in substitution for an AWE amount for that quarter that was previously published by the Australian Statistician;
the publication of the later amount is to be disregarded for the purposes of this section.
