(1) For the purposes of the definition of adjustment percentage in clause 12 (1), the percentage for a year is to be calculated—

(a) if the Index number for the June quarter in that year is greater than the Index number for the immediately preceding June quarter—in accordance with the following formula—

(b) if the Index number for the June quarter in that year is less than the Index number for the immediately preceding June quarter—in accordance with the following formula—

where, in the case of either formula—

P is the percentage to be calculated, and

C is the Index number for the June quarter in that year, and

L is the Index number for the immediately preceding June quarter.

(2) If—

(a) the percentage calculated for a year in accordance with subclause (1) (b) is less than 1.1%, or

(b) the Index number for the June quarter in that year is the same as the Index number for the immediately preceding June quarter,

there is taken to be no adjustment percentage for that year.

(3) If there is taken to be no adjustment percentage for a year (the first-mentioned year), then, for the purposes of calculating the percentage for the next year—

(a) the Index number for the June quarter in the first-mentioned year is taken not to have been published, and

(b) the Index number for that quarter is taken to be the same as the Index number for the June quarter in the last year for which there was an adjustment percentage.

(4) If at any time, whether before, on or after 1 June 2003, the Australian Statistician has published in respect of a particular June quarter an Index number in substitution for an Index number previously published in respect of that quarter, then, for the purposes of this Part—

(a) except as provided by paragraph (b)—the publication of the later Index number is to be disregarded, or
