(1) In this section:
"index number" , in relation to a quarter, means the All Groups Consumer Price Index number, being the weighted average of the 8 capital cities, published by the Australian Statistician in respect of that quarter.
(2) Subject to subsection (3), if at any time, 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 by the Australian Statistician in respect of that quarter, the publication of the later index number shall be disregarded for the purposes of this section.
(3) If at any time, 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 shall be had only to index numbers published in terms of the new index reference period.
(4) A reference in subsection 60(7) to the guideline price of an estate or interest in land is a reference to:
(a) if the factor ascertained in accordance with subsections (5) and (6) in relation to the market value of the estate or interest as at the time the estate or interest was acquired by the employee is greater than 1--the market value as at that time multiplied by that factor; or
(b) in any other case--the market value as at that time.
(5) The factor to be ascertained for the purposes of subsection (4) in relation to the market value of the estate or interest in land as at the time of the acquisition of the estate or interest by the employee is the number (calculated to 3 decimal places) ascertained by dividing the index number in respect of the quarter of the year in which the employee sold the estate or interest to the provider by the index number in respect of the quarter of the year in which the estate or interest was acquired by the employee.
(6) Where the factor ascertained in accordance with subsection (5) would, if it were calculated to 4 decimal places, end with a number greater than 4, that factor shall be taken to be the factor calculated to 3 decimal places in accordance with that subsection and increased by 0.001.
