13Calculation of adjustment
percentage
(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
(b)
if the Minister so directs—regard is, after
the direction is given, to be had only to the later and not to the earlier
Index number.
(5)
Despite subclause (4), if at any time on or after
1 June 2003, the Australian Statistician changes the reference base for the
Consumer Price Index (All Groups Index) for Sydney, then, for the purposes of
the application of this Part after the change takes place, regard is to be had
only to Index numbers published in terms of the new reference
base.
