(b) the number calculated (to 3 decimal places) by dividing the AWOTE amount for the December quarter in the preceding year by the AWOTE amount for the December quarter in the year preceding that year.
The December quarter is a quarter beginning on 1 October.
The AWOTE amount for a quarter is the estimate of the full-time adult average weekly ordinary time earnings for persons in Australia for the middle month of the quarter published by the Australian Statistician in relation to the month.9(3) [Later estimate to be disregarded]
If the Australian Statistician publishes an estimate of full-time adult average weekly ordinary time earnings for persons in Australia for a period for which such an estimate was previously published by the Australian Statistician, the publication of the later estimate is to be disregarded for the purposes of this section.9(4) [Number calculated to 3 decimal places]
If the number calculated for the purposes of paragraph (1)(b) in relation to a year would, if calculated to 4 decimal places, end with a numeral higher than 4, the number is to be taken to be the number calculated to 3 decimal places and increased by 0.001.
