(2) For each levy payer, the Corporation must calculate the LRG modifier— (a) (b) for each tax year in the experience period; and for each levy risk group the levy payer is in, within each tax year in the experience period.
15A Calculation of rehabilitation component of LRG modifier (1) The Corporation must calculate the rehabilitation component using the follow‐ ing formula: [(payer’s rate − payers’ rate) ÷ payers’ rate] × credibility weighting where— payer’s rate means the experience rate of the levy payer for the applicable levy risk group calculated using the formula in subclause (3) payers’ rate means the experience rate of all the levy payers in the applicable levy risk group calculated using the formula in subclause (4) credibility weighting means the credibility weighting determined in accord‐ ance with regulation 15C.
(2) However, if the rehabilitation component calculated for each levy risk group in accordance with subclause (1)— (a) (b) is greater than 0.75, the Corporation must disregard the result and treat the component as 0.75: is less than −0.50, the Corporation must disregard the result and treat the component as −0.50.
(3) The Corporation must calculate the payer’s rate using the following formula: compensation days ÷ earnings where— compensation days— (a) means the total number of weekly compensation days that— (i) fall within the claims activity period; and 6 Version as at 1 April 2022 Accident Compensation (Experience Rating) Amendment Regulations 2020 r 14 (ii) relate to the levy payer’s qualifying claims in the applicable levy risk group; but (b) any qualifying claim that exceeds 365 weekly compensation days within the claims activity period must be counted as 365 weekly compensation days earnings means the total of the levy payer’s liable earnings in the applicable tax year.
(4) The Corporation must calculate the payers’ rate using the following formula: compensation days ÷ earnings where— compensation days— (a) means the total number of weekly compensation days that— (i) (ii) fall within the claims activity period; and relate to the qualifying claims of all levy payers in the applicable levy risk group; but (b) any qualifying claim that exceeds 365 weekly compensation days within the claims activity period must be counted as 365 weekly compensation days earnings means the total of the liable earnings of the levy payers in the applic‐ able levy risk group in the applicable tax year.
15B Calculation of risk management component of LRG modifier (1) The Corporation must calculate the risk management component using the fol‐ lowing formula: [(payer’s rate − payers’ rate) ÷ payers’ rate] × credibility weighting where— payer’s rate means the experience rate of the levy payer for the applicable levy risk group calculated using the formula in subclause (3) payers’ rate means the experience rate of all the levy payers in the applicable levy risk group calculated using the formula in subclause (4) credibility weighting means the credibility weighting determined in accord‐ ance with regulation 15C.
(2) However, if the risk management component calculated for each levy risk group in accordance with subclause (1)— (a) (b) is greater than 0.75, the Corporation must disregard the result and treat the component as 0.75: is less than −0.50, the Corporation must disregard the result and treat the component as −0.50.
(3) The Corporation must calculate the payer’s rate using the following formula: 7 r 14 Accident Compensation (Experience Rating) Amendment Regulations 2020 Version as at 1 April 2022 claims and deaths ÷ earnings where— claims and deaths means the sum of— (a) (b) the number of the qualifying claims of the levy payer in the applicable levy risk group for which the Corporation paid an amount greater than $500 in the claims activity period for qualifying costs of treatment; and the number of the qualifying claims of the levy payer in the applicable levy risk group that involve the death of a current or former employee of an employer or the death of a private domestic worker earnings means the total of the levy payer’s liable earnings in the applicable levy risk group in the applicable tax year.
(4) The Corporation must calculate the payers’ rate using the following formula: claims and deaths ÷ earnings where— claims and deaths means the sum of— (a) (b) the number of the qualifying claims of all the levy payers in the applic‐ able levy risk group for which the Corporation paid an amount greater than $500 in the claims activity period for qualifying costs of treatment; and the number of the qualifying claims of all the levy payers in the applic‐ able levy risk group that involve the death of a current or former employee of an employer or the death of a private domestic worker earnings means the total of the liable earnings of all the levy payers in the applicable levy risk group in the applicable tax year.
15C Meaning of credibility weighting The Corporation must determine the credibility weightings referred to in regu‐ lations 15A(1) and 15B(1) using the applicable formula in paragraphs (a) to (h) or the credibility weighting in paragraph (i), as follows: (a) (b) (c) if the liable earnings (LE) of the levy payer in the tax year are $110,000 or less, the credibility weighting is the result of— 0.05 × √(LE ÷ $110,000) if the liable earnings (LE) of the levy payer in the tax year are over $110,000 and equal to or under $277,000, the credibility weighting is the result of— 5% + {0.05 × √[(LE − $110,000) ÷ $167,000]} if the liable earnings (LE) of the levy payer in the tax year are over $277,000 and equal to or under $567,000, the credibility weighting is the result of— 8 Version as at 1 April 2022 Accident Compensation (Experience Rating) Amendment Regulations 2020 r 14 (d) (e) (f) (g) (h) 10% + {0.05 × √[(LE − $277,000) ÷ $290,000]} if the liable earnings (LE) of the levy payer in the tax year are over $567,000 and equal to or under $1,100,000, the credibility weighting is the result of— 15% + {0.05 × √[(LE − $567,000) ÷ $533,000]} if the liable earnings (LE) of the levy payer in the tax year are over $1,100,000 and equal to or under $2,767,000, the credibility weighting is the result of— 20% + {0.1 × √[(LE − $1,100,000) ÷ $1,667,000]} if the liable earnings (LE) of the levy payer in the tax year are over $2,767,000 and equal to or under $5,567,000, the credibility weighting is the result of— 30% + {0.1 × √[(LE − $2,767,000) ÷ $2,800,000]} if the liable earnings (LE) of the levy payer in the tax year are over $5,567,000 and equal to or under $11,100,000, the credibility weighting is the result of— 40% + {0.1 × √[(LE − $5,567,000) ÷ $5,533,000]} if the liable earnings (LE) of the levy payer in the tax year are over $11,100,000 and equal to or under $75,000,000, the credibility weighting is the result of— 50% + {0.5 × √[(LE − $11,100,000) ÷ $63,900,000]} (i) if the liable earnings of the levy payer in the tax year are
 over $75,000,000, the credibility weighting is 100%.
15D Determination of tax year modifier (1) (2) (3) For the purposes of regulation 12(4), the Corporation must use the LRG modi‐ fier for each levy risk group the levy payer is in to determine the levy payer’s tax year modifier for each tax year in the experience period.

If the levy payer is in only 1 levy risk group in a tax year in the experience period, the Corporation must treat the levy payer’s LRG modifier for the tax year as being the levy payer’s tax year modifier.
If the levy payer is in 2 or more levy risk groups in a tax year in the experience period, the Corporation must determine the levy payer’s tax year modifier by,— (a) first, for each levy risk group the levy payer is in, using the following formula: LRG modifier × (levy ÷ total levy) where— LRG modifier means the LRG modifier for the relevant levy risk group calculated in accordance with regulation 15 9 r 14 Accident Compensation (Experience Rating) Amendment Regulations 2020 Version as at 1 April 2022 levy means the levy paid or payable by the levy payer in the applicable tax year for the relevant levy risk group total levy means the total levy paid or payable under section 167(4) by the levy payer in the applicable tax year, across all applicable levy risk groups; and (b) secondly, adding up all the results of the calculations in paragraph (a).
15E Calculation of experience period modifier For the purposes of regulation 12(5), the Corporation must calculate the levy payer’s experience period modifier using the following formula: (year 1 tax year modifier × 40 ÷ 210) + (year 2 tax year modifier × 70 ÷ 210) + (year 3 tax year modifier × 100 ÷ 210) where— year 1 tax year modifier, in relation to the levy year starting on 1 April 2020 and ending on the close of 31 March 2021, means the tax year modifier calcu‐ lated in accordance with regulation 15D for the tax year starting on 1 April 2016 and ending on the close of 31 March 2017 year 2 tax year modifier, in relation to the levy year starting on 1 April 2020 and ending on the close of 31 March 2021, means the tax year modifier calcu‐ lated in accordance with regulation 15D for the tax year starting on 1 April 2017 and ending on the close of 31 March 2018 year 3 tax year modifier, in relation to the levy year starting on 1 April 2020 and ending on the close of 31 March 2021, means the tax year modifier calcu‐ lated in accordance with regulation 15D for the tax year starting on 1 April 2018 and ending on the close of 31 March 2019.
15F Rounding experience period modifier to calculate loading or discount (if any) This regulation applies unless regulation 15G(1) applies.
For the purposes of regulation 12(6), the Corporation must round the levy pay‐ er’s experience period modifier as follows: (a) if the experience period modifier is a negative number, the Corporation must apply a discount to the section 167(4)(a) levy payable by the levy payer in the applicable levy year in accordance with the following table: Result of calculation under regulation 15E Equal to or under -0.45 Over −0.45 and equal to or under −0.35 Over −0.35 and equal to or under −0.25 Over −0.25 and equal to or under −0.15 Over −0.15 and equal to or under −0.05 −0.50 −0.40 −0.30 −0.20 −0.10 Discount to be applied (1) (2) 10 Version as at 1 April 2022 Accident Compensation (Experience Rating) Amendment Regulations 2020 r 17 (b) if the experience period modifier is a positive number, the Corporation must apply a loading to the section 167(4)(a) levy payable by the levy payer in the applicable levy year in accordance with the following table: Result of calculation under regulation 15E Over 0.05 and equal to or under 0.15 Over 0.15 and equal to or under 0.25 Over 0.25 and equal to or under 0.35 Over 0.35 and equal to or under 0.45 Over 0.45 and equal to or under 0.55 Over 0.55 and equal to or under 0.65 Over 0.65 +0.10 +0.20 +0.30 +0.40 +0.50 +0.60 +0.75 Loading to be applied 15G Application of discount or loading (if any) (1) (2) The Corporation must not apply a discount or a loading to the section 167(4)(a) levy payable by the levy payer in the applicable levy year if the levy payer’s experience period modifier calculated under regulation 15E is over −0.05 and equal to or under 0.05.
In all other cases, for the purposes of regulation 12(7) the Corporation must apply the discount or loading to the levy paid or payable by the levy payer in the applicable levy year using the following formula: where— levy × discount/loading levy means the total levy paid or payable under section 167(4)(a) by the levy payer in the applicable levy year discount/loading means the discount to be applied or the loading to be applied, calculated in accordance with regulation 15F.
15 Regulation 16 revoked (Experience rating modification: when result of calculation must be disregarded) Revoke regulation 16.

16 Regulation 24 amended (Revocation and saving) After regulation 24(2), insert: (2A) These regulations apply to the levy year starting on 1 April 2019 and ending on 31 March 2020, as if they had not been amended by the Accident Compensa‐ tion (Experience Rating) Amendment Regulations 2020.

11 Explanatory note Accident Compensation (Experience Rating) Amendment Regulations 2020 Version as at 1 April 2022 Michael Webster, Clerk of the Executive Council.

Explanatory note This note is not part of the regulations, but is intended to indicate their general effect.

These regulations, which come into force on 1 April 2020, amend the Accident Com‐ pensation (Experience Rating) Regulations 2019 (the principal regulations).
The principal regulations prescribe the experience rating system for adjusting the amount of Work Account levies payable by a person in an industry, based on the per‐ son’s claims history.
These regulations make the following changes to the processes for calculating the level of any adjustment of the person’s levy: • • • • • the industry size modifier, which provided a discount or loading based on the performance of the levy payer’s peers, is removed: the off-balance adjustment from the experience rating modification formula, which was designed to make discounts and loadings balance out, is removed: weightings are added to the experience rating calculations for each of the 3 pre‐ vious years in the experience period to improve the responsiveness to the levy payer’s most recent history: the levels of liable earnings, at which each credibility weighting applies to each levy payer, are lowered: discounts and loadings are rounded, to manage levy volatility associated with small changes from year to year.
The amendments mean that calculations will be made separately for each tax year before being added together.

The amendments will apply to the levy year starting on 1 April 2020 and ending on 31 March 2021.
