"adjusted previous year's duty" , in relation to a prescribed new production area in relation to a month of a financial year, means the amount of duty that, at the end of the financial year immediately preceding the financial year in which that month occurs, would have been payable in respect of new oil produced from that area and entered for home consumption during that preceding year if, for the prices that were, at the end of that preceding year, the applicable petroleum prices for all of the months of that preceding year, there had been substituted the prices that are, at the end of that first - mentioned month, the respective applicable petroleum prices for all of those months.

"prescribed new production area" means a new petroleum production area prescribed by by - laws (which, without limiting the generality of the foregoing, may be a relevant accumulation, a well, an oilfield or a gas field).
Introduction
(2) The amount of duty in respect of new oil ascertained in accordance with this section shall be ascertained by reference to the prescribed new production area from which the oil is produced and to the month of a financial year during which the oil is entered for home consumption.
The amount of duty
(3) Subject to subsection (3A), the amount of duty in respect of new oil produced from a prescribed new production area and entered for home consumption during a month of a financial year commencing on or after 1 July 2001 is the amount worked out using the formula:
where:

"debited adjustment amount" is the debited adjustment amount (if any) for that area and that month, worked out in accordance with subsection (5A).

(a) any increases in the amount of duty paid as a result of the addition of debited adjustment amounts for that area for any of the preceding months of that year;
(b) any decreases in that amount as a result of the subtraction of credited adjustment amounts for that area for any of those months.
The total amount of notional duty
(4) The amount of notional duty in respect of new oil produced from a particular prescribed new production area and entered for home consumption during a particular period is the sum of the amounts of notional duty in respect of:
(a) the quantity (if any) of the oil that exceeds 
but does not
exceed 
;
(b) the quantity (if any) of the oil that exceeds 
but does not
exceed 
;
(c) the quantity (if any) of the oil that exceeds 
but does not
exceed 
; and
(d) the quantity (if any) of the oil that exceeds 
;
where:
"A" is the number of days in the period.
"B" is:
(a) where the period in a year in which there are 365 days--136.98630 kilolitres; or
(b) where the period is in a year in which there are 366 days--136.61202 kilolitres.
The amount of notional duty for a quantity of oil--one petroleum price
(5) Subject to subsections (6) and (9), the amount of notional duty in respect of a quantity of oil referred to in subsection (4) is an amount equal to the relevant percentage (set out in subsection (7)) of the product of:
(a) the amount specified in the price that is, at the end of the period referred to in subsection (4) in relation to the quantity of oil, the applicable petroleum price for the month in which the period comes to an end; and
(b) the number of kilolitres in that quantity;
calculated to the nearest cent.
The debited adjustment amount
(5A) Where:
(a) during a month of a financial year, a VOLWARE price for stabilised crude petroleum oil for a month of the immediately preceding financial year and a particular prescribed new production area is determined under section 7 of the Petroleum Excise (Prices) Act 1987 ; and
(b) the adjusted previous year's duty for that prescribed new production area for that first - mentioned month is greater than the non - adjusted previous year's duty for that area for that first - mentioned month;
there is a debited adjustment amount for that area for that first - mentioned month, being an amount equal to the difference between that adjusted previous year's duty and that non - adjusted previous year's duty.
The credited adjustment amount
(5B) Where:
(a) during a month of a financial year, a VOLWARE price for stabilised crude petroleum oil for a month of the immediately preceding financial year and a particular prescribed new production area is determined under section 7 of the Petroleum Excise (Prices) Act 1987 ; and
(b) the adjusted previous year's duty for that prescribed new production area for that first - mentioned month is less than the non - adjusted previous year's duty for that area for that first - mentioned month;
there is a credited adjustment amount for that area for that first - mentioned month, being an amount equal to the difference between that non - adjusted previous year's duty and that adjusted previous year's duty.
The amount of notional duty for a quantity of oil--more than one petroleum price
(6) Where, at the end of a period in a financial year, the applicable petroleum prices for the months in which the period occurs and a particular prescribed new production area are not all the same, the amount of the notional duty in respect of a quantity of oil referred to in subsection (4) produced from that production area and entered for home consumption during the period is an amount equal to the relevant percentage (set out in subsection (7)) of the sum of the amounts calculated in respect of each such applicable petroleum price in operation during the period in accordance with the formula:
where:
"P" is the amount specified in the applicable petroleum price.
"Q" is the number of kilolitres in the quantity of oil referred to in subsection (4).
"K" is the number of kilolitres of new oil produced from that production area and entered for home consumption during that part of the period during which the applicable petroleum price was in operation.
"KT" is the number of kilolitres of new oil produced from that production area and entered for home consumption during the period.
Relevant percentage for a quantity of oil
(7) For the purposes of subsections (5) and (6), the relevant percentage in relation to a quantity of oil referred to in subsection (4) is:
(a) in the case of a quantity to which paragraph 4(a) applies--10%; and
(b) in the case of a quantity to which paragraph 4(b) applies--15%; and
(c) in the case of a quantity to which paragraph 4(c) applies--20%; and
(d) in the case of a quantity to which paragraph 4(d) applies--30%.
Rounding the number of kilolitres in a quantity of oil
(8) For the purposes of subsections (5) and (6), the number of kilolitres in a quantity of oil shall be taken to be a number equal to:
(a) unless paragraph (b) applies--the number of kilolitres in that quantity calculated to 1 decimal place; or
(b) where the number of kilolitres in that quantity calculated to 2 decimal places ends in a number greater than 4--the number of kilolitres in that quantity calculated to 1 decimal place increased by 0.1.
The amount of notional duty--dealing with the first year of production
(9) When no new oil produced from a particular prescribed new production area was ever entered for home consumption before the expiration of the first month of a particular financial year, then, in ascertaining, in accordance with subsections (4), (5) and (7) or (4), (6) and (7), the notional duty in respect of new oil produced from the production area and entered for home consumption during a later month (in this subsection referred to as the relevant month ) of that financial year, those subsections have effect in relation to the new oil as if each reference in a paragraph of subsection (4) to B were a reference to the product of B and the factor ascertained in accordance with the formula:
where:
"M" is the number of days in the period commencing on the day on which new oil produced from the prescribed new production area was first entered for home consumption and ending on the expiration of the relevant month; and
