Schedule 1—Determination of annual adjustment factor
1—Annual adjustment factor
	(1)	The annual adjustment factor for a financial year (the relevant year) is to be calculated in accordance with this clause.
	(2)	First, the following formula is to be applied:

where—
RA means the Rural Arterial Road Expenditure adjustment factor that applies for that year (see clause 2)
RL means the Rural Local Road Expenditure adjustment factor that applies for that year (see clause 2)
UA means the Urban Arterial Road Expenditure adjustment factor that applies for that year (see clause 2)
UL means the Urban Local Road Expenditure adjustment factor that applies for that year (see clause 2). 
	(3)	Second, the amount determined in accordance with subclause (2) is to be rounded up or down to 1 decimal place (rounding an amount of 0.05 upwards).
Example—
An amount of 3.55 would be rounded up to 3.6.
	(4)	The result is the raw annual adjustment factor (RAAF) expressed as a percentage.
	(5)	If the annual report of the National Transport Commission for the financial year that ended 1 year before the start of the relevant year does not provide the information needed to calculate the value of TFU in clause 3 and the values of HV and TTR in clause 4, then the raw annual adjustment factor is the annual adjustment factor for the relevant year.
	(6)	If subclause (5) does not apply, then the following formula is to be applied:

where—
PRABC is the Revised Adjusted Base Cost derived in calculating the annual adjustment factor in the previous financial year.
	(7)	The result is the Revised Adjusted Base Cost (RABC).
	(8)	Next, the following formula is to be applied:

where—
FR means the estimated total amount of the road user charge under the Fuel Tax Act 2006 of the Commonwealth as calculated in accordance with clause 3
RR means the estimated revenue raised in relation to heavy vehicles by registration charges in Australia as calculated in accordance with clause 4.
	(9)	Finally, the amount determined under subclause (8) is to be rounded up or down to 1 decimal place (rounding an amount of 0.05 upwards).
	(10)	The result is the annual adjustment factor expressed as percentage.
2—Adjustment factors
	(1)	The 4 adjustment factors referred to in clause 1 (RA, RL, UA, UL) for a particular financial year are to be calculated in accordance with this clause.
	(2)	First, the expenditure for each adjustment factor for the Years 1 to 6 is to be multiplied by the following fraction to derive an amount of adjusted expenditure for each of those years for each of those factors:

where—
expenditure, for a financial year, means the amount specified in the most recent annual report of the NTC as being—
	(a)	in the case of RA—the estimated amount of expenditure on rural arterial roads for that year; and
	(b)	in the case of UA—the estimated amount of expenditure on urban arterial roads for that year; and
	(c)	in the case of RL—the estimated amount of expenditure on rural local roads for that year; and
	(d)	in the case of UL—the estimated amount of expenditure on urban local roads for that year;
index number, for a particular financial year, means the road construction and maintenance price index number for 30 June of that year published by the Bureau of Infrastructure, Transport and Regional Economics;
Example—
In August 2007 the Bureau of Infrastructure, Transport and Regional Economics published its index figure. As at 30 June 2007 the index number was 150.5. Thus the index number for the financial year that commenced on 1 July 2006 is 150.5.
most recent annual report of the NTC means the last annual report of the NTC that was tabled in each House of the Commonwealth Parliament before the start of the financial year for which the annual adjustment factor is being determined;
NTC means the National Transport Commission;

Year 2 means the financial year immediately before Year 3;
Year 3 means the financial year immediately before Year 4;
Year 4 means the financial year immediately before Year 5;
Year 5 means the financial year immediately before Year 6;
Year 6 means the financial year immediately before Year 7;
Year 7 means the financial year immediately before Year 8;
Year 8 means the latest financial year for which the amount of estimated expenditure on the relevant type of road mentioned in the definition of expenditure is specified in the most recent annual report of the NTC.
Examples of the determination of Year 8—
Suppose that, on 1 March 2010, the most recent annual report of the NTC to have been tabled is the annual report for 2008/2009, and that report contains estimated expenditure figures for arterial roads up to and including the 2008/2009 financial year and estimated expenditure figures for local roads up to and including the 2006/2007 financial year. For the purpose of calculating RA and UA for the 2010/2011 financial year, Year 8 is the 2008/2009 financial year. For the purpose of calculating RL and UL for the 2010/2011 financial year, Year 8 is the 2006/2007 financial year.
Example of the calculation of the amount of adjusted expenditure for a year—
Suppose that the Estimated Urban Arterial Road Expenditure for Year 4 is $2 010 000 000; that the index number for Year 4 is 129.7; and that the index number for Year 7 is 154.26. The adjusted expenditure for UA for Year 4 is $2 390 613 720 (that is (154.26/129.7) x $2 010 000 000). 
	(3)	Second, for each adjustment factor, the amount of adjusted expenditure for each of Years 1 to 6 is to be added together, and the expenditure for Year 7 is to be added to the total to derive the Combined Adjusted Expenditure for Years 1 to 7.
	(4)	Third, the expenditure for each adjustment factor for Years 2 to 7 is to be multiplied by the following fraction to derive an amount of adjusted expenditure for each of those years for each of those factors:

	(5)	Fourth, for each adjustment factor, the amount of adjusted expenditure for each of Years 2 to 7 is to be added together, and the expenditure for Year 8 is to be added to the total to derive the Combined Adjusted Expenditure for Years 2 to 8.
	(6)	Fifth, for each adjustment factor, the following formula is to be applied:

where—
Combined Adjusted Expenditure for Years 2 to 8—see subclause (5)
Combined Adjusted Expenditure for Years 1 to 7—see subclause (3).
	(7)	Lastly, the amount determined in accordance with subclause (6) is to be rounded up or down to 4 decimal places (rounding an amount of 0.00005 upwards).
Example—
An amount of 2.35065 would be rounded up to 2.3507.
	(8)	The result is the amount that is to be used for that adjustment factor in the formula set out in clause 1(2).
3—Calculation of the estimated total amount of the road user charge
	(1)	The estimated total amount of the road user charge under the Fuel Tax Act 2006 of the Commonwealth is to be calculated in accordance with this clause.
	(2)	First, the following formula is to be applied:

where—
TFU is the total fuel use by heavy vehicles in litres determined by adding together the estimated annual fuel use shown in the relevant annual report of the NTC for each category of heavy vehicle
RUC is the road user charge rate (expressed in dollars) for the previous year that applied under section 43‑10 of the Fuel Tax Act 2006 of the Commonwealth, or if more than 1 rate applied in that year, the last rate that applied in that year
previous year means the financial year that immediately preceded the relevant year
relevant annual report of the NTC means the annual report of the National Transport Commission for the financial year that ended 1 year before the start of the relevant year
relevant year means the financial year for which the annual adjustment factor is being calculated.
	(3)	Second, the amount determined under subclause (2) is to be divided by 1 000 000.
	(4)	Third, the amount determined under subclause (3) is to be rounded up or down to 2 decimal places (rounding an amount of 0.005 upwards).
	(5)	The result is the estimated total amount of the road user charge.
4—Calculation of estimated revenue raised from registration charges
	(1)	The estimated revenue raised in relation to heavy vehicles by registration charges in Australia (RR) is to be calculated in accordance with this clause.
	(2)	First, the following formula is to be applied:

where—
HV is the sum of the amounts shown in the relevant annual report of the NTC as the estimated vehicle registration revenue excluding trailers for each category of heavy vehicle
TTR is the sum of the amounts shown in the relevant annual report of the NTC as the estimated trailer registration revenue for each relevant category of heavy vehicle
relevant annual report of the NTC means the annual report of the National Transport Commission for the financial year that ended 1 year before the start of the financial year for which the annual adjustment factor is being calculated.
	(3)	Second, the amount determined under subclause (2) is to be divided by 1 000 000.
	(4)	Third, the amount determined under subclause (3) is to be rounded up or down to 2 decimal places (rounding an amount of 0.005 upwards).
	(5)	The result is the estimated revenue raised in relation to heavy vehicles by registration charges in Australia.
5—Transitional provision relating to the calculation of the annual adjustment factor for 2010/2011 financial year
Despite anything to the contrary in clause 1, for the purposes of calculating the annual adjustment factor for the financial year commencing on 1 July 2010—
	(a)	the PRABC referred to in clause 1(6) is to be taken to be 2015.15; and
	(b)	a reference to the relevant annual report of the NTC in clauses 3 and 4 is a reference to the tables published by the National Transport Commission before 1 July 2010 in the Commonwealth Government Gazette for the purposes of this Schedule.
