1. Introduction
These guidelines provide mechanisms for the regulation of insurance premiums matters
under Part 2, Division 2.3 and clause 2 of Schedule 4 Motor Accident Injuries Act 2017

(the MAI Act) issued by the State Insurance Regulatory Authority (SIRA).

2. Commencement and revocation of

previous guidelines

These guidelines are effective for premium rate filings submitted for all third-party policies that the filing insurer proposes to issue with a commencement date on or after 1 December 2017, replacing any prior guidelines, and will remain in force until amended or replaced.

3. Definitions

The definitions in the MAI Act apply to these guidelines.

4. Guiding principles

The primary objects of the MAI Act[1] relating to a premium framework are to:

promote competition and innovation in the setting of premiums
ensure the sustainability and affordability of the scheme and fair market practices

keep premiums affordable by ensuring that the profits realised by insurers do not exceed the amount that is sufficient to underwrite the relevant risk

SIRA seeks to achieve these objects in managing third-party insurance premiums.

To promote competition and innovation by insurers, SIRA allows risk-based pricing, but this must be done within limits in order to keep premiums affordable. The premium framework recognises that this liability scheme, which is compulsory and privately underwritten, blends risk-based and community-rated approaches to assist with the object of affordability.

Filed premiums are required to be adequate and not excessive[2]. Filed premiums will be closely scrutinised by SIRA against the objects of the MAI Act and against any range of premiums for transitional policies determined by SIRA under clause 2 (3)(c) of Schedule

4 Savings, transitional and other provisions.

In aligning with the competition and innovation objects, SIRA recognises that insurers will pursue their own particular business objectives that will be reflected as an integral Published LW 17 August 2017 (2017 No 403)

part of each insurer’s pricing strategy. On this basis, technical (actuarial) pricing will not
be considered in isolation and explanation by insurers is encouraged for non-technical

pricing considerations including:

business plans and short, medium and long term growth strategies
response to pricing by competitors
market segmentation and distribution strategies
innovation and efficiencies in their business model

SIRA will take into account the objects of the MAI Act by considering in aggregate both
qualitative and quantitative explanations when reviewing insurer filings. SIRA
recognises that in the early stages of the MAI Act relevant data will be limited and more

weight on qualitative considerations may be appropriate.

5. Filing under Division 2.3 of the MAI

Act

In submitting a full or partial rate filing a licensed insurer must provide a soft copy of the filing including a covering letter, the filing report, appendices and any associated spreadsheets. The covering letter is to be signed by the NSW CTP Product Executive or

equivalent office holder and must include:

a description of the type of filing[3], proposed effective date and, if applicable, any period nominated by the insurer for rejecting the filing exceeding 6 weeks

an executive summary of the filing
overall average premium

any significant changes to the most recent business plan delivered to SIRA impacting competitive strategies or market positioning

significant rating factor changes
changes in bonus malus levels, and
an outline of the policyholder impact analysis

6. Rejection of premiums by SIRA

SIRA may reject[4] a premium filed under Division 2.3 of the MAI Act if it is of the opinion that the premium:

is excessive or inadequate in relation to actuarial advice and to other relevant financial information available to SIRA

does not conform to the relevant provisions of these Guidelines, or

will not fall within the range of premiums determined by SIRA under clause 2 (3)(c) of Schedule 4, Savings, transitional and other provisions.

SIRA will conduct a review of all filings lodged in accordance with Division 2.3 of the financial advice.

Published LW 17 August 2017 (2017 No 403)

SIRA’s review will consider:

whether a filing is considered incomplete. Completeness will be determined by being satisfied that there is materially sufficient explanation of the assumptions and filed premiums to enable a review of the quantitative and qualitative elements of the filing. If classified as incomplete, SIRA may request further information from the insurer in accordance with section 2.20(7) of the MAI Act which will mean that time does not run in relation to the period allowed for rejecting the premium until the insurer complies with the SIRA request. Alternatively SIRA may request its withdrawal and, if not withdrawn, will exercise its discretion to reject the filing.

whether the premium has been determined in accordance with the process set out in these Guidelines. This will include the requirements for additional information provided with the premiums filed and to justify premiums that have been filed.

7. Special provisions for premiums

during the transitional period

SIRA has determined the likely cost of claims for claims arising after the start of the transition period to be consistent with the initial costing by SIRA’s independent actuary subject to any subsequent costing variations.

In determining SIRA’s opinion on whether the premium is adequate and not excessive under section 2.22(1)(a) of the MAI Act SIRA will consider the comparison between the assumptions in the insurer’s filing and those in the independent actuary’s costing published by SIRA.

7.1 Comparison with industry

During the transition period[5], insurers must provide a comparison of the assumptions made to allow for scheme benefit changes with SIRA’s independent actuary’s costing assumptions (Schedule E), taking into account insurers’ business mix by class and

region and other (claims experience related) factors, against those of the industry.

7.2 Taxi and motorcycle average premium changes

Insurers must provide a summary of changes in average premium for vehicle classes 7 and 10 for any filing for premiums to be charged on or after 1 December 2017.

Published LW 17 August 2017 (2017 No 403)

8. Premium components and factors to

be calculated

8.1 Motor Accident Schedule of Premium Relativities

Insurers must classify vehicles based on the Motor Accident Schedule of Premium

Relativities. SIRA will publish two sets of Premium Relativities:

(1) Customer Premium Relativities’ which are to be used to calculate customer
premiums

(2) ‘Insurer Premium Relativities’ which are used in Appendix A - Schedule C to arrive at Insurers Base Premium

These schedules will be published to licensed insurers each year or other period as determined by SIRA. Insurers must apply the relevant premium relativities that are applicable to the vehicle class and region.

8.2 Base premium

The base premium for each vehicle classification and region must be calculated as:

(1) the Class 1 Metro vehicle base premium for which the policyholder is not entitled to
any Input Tax Credit (ITC)

(2) multiplied by the relativity for the particular vehicle class and region published in

the Motor Accident Schedule of Insurer Premium Relativities current at the date the
third-party policy begins

(3) divided by 100.

The nominated base premium is used to define the allowable range of premiums in terms of the limits for bonus malus, the relative premiums for vehicle classifications and regions, and the loading which allows for policyholder entitlement to an ITC. It is equal to:

where
= the insurer’s base premium for Class 1 Metro including GST but
excluding the Fund levy, calculated as if no policyholders are entitled to any ITC.

The Fund levy is the combined total of the SIRA Motor Accidents Operational Fund (MAF) levy, Lifetime Care and Support Authority Fund (LTCS) levy and Motor Accident Injuries Treatment and Care Benefits Fund (MAITC) levy.

the insurer’s average premium including GST but excluding Fund levy,

calculated as if no policyholders are entitled to any ITC, as shown in the Premium
Filing Summary Sheet (Appendix A - Schedule C)

the premium relativity applicable to the i-th policy, as

Published LW 17 August 2017 (2017 No 403)

bmi = bonus malus rate (%) applicable to the i-th policy, as anticipated to be
underwritten over the period of the premium filing
n = number of policies anticipated to be underwritten over the period of the
premium filing.

Insurers must provide the filed base premium for each vehicle class and rating region in accordance with this clause in an electronic spreadsheet designated Schedule A.

8.3 Ratio of insurer’s average premium to Class 1 Metro
(Item 13 in Appendix A - Schedule C)

This factor expresses the ratio of the insurer’s average premium based on the insurer’s projected portfolio mix[6] (taking into account the insurer’s vehicle class and region mix of business), relative to the base premium of a Class 1 Metro vehicle. This is calculated by:

(1) determining the percentage of the insurer’s projected portfolio (based on the
number of vehicles) that will be written in each vehicle class and region

(2) multiplying each of the above proportions by the Motor Accident Schedule of

Premium Relativities premium relativities published by SIRA for the corresponding vehicle class and region

(3) adding up all of the values calculated in (2) above

(4) dividing (3) by 100

The formula for the calculation is:

where

αk = proportion (as a %) of the insurer’s projected portfolio (based on vehicle

count) for the k-th vehicle class and region

= premium relativity for the k-th vehicle class and region

in the Motor Accident Schedule of Insurer Premium Relativities published by
SIRA.

8.4 Bonus malus factor (Item 14 in Appendix A - Schedule C)

This factor expresses the average bonus malus applied by an insurer to its projected annual policy equivalent portfolio (after taking into account the insurer’s vehicle class and region mix of business). This is calculated by:

(1) determining the total portfolio premium (before GST and levies) to be collected,
inclusive of the bonus malus rates to be applied, for the portfolio of risks projected
to be written by the insurer. The portfolio of risks projected to be written by the
insurer should take into account the mix of business by vehicle class, region and
insurer’s rating factors

(2) determining the total portfolio premium (before GST and levies) to be collected,

before the application of any bonus malus rates, for the portfolio of risks projected
to be written by the insurer

Published LW 17 August 2017 (2017 No 403)

(3) dividing (1) by (2)

The formula for the calculation is:

where

base premiumi = applicable base premium ($) for the i-th policy based on its

vehicle class and rating region

bmi = bonus malus rate (%) applicable to the i-th policy given the rating factors

and bonus malus structure adopted by the insurer.

8.5 Bonus malus limits, rating structure and risk rating
factors

Each risk rating factor proposed by an insurer must be objective and evidence based. A risk rating factor must not be used unless approved by SIRA. Insurers can apply to use objective risk rating factors except race, policy duration, input tax credit entitlement and postcode.

Applications by insurers to use innovative rating factors that differentiate risk with quantifiable data including telematics are encouraged by SIRA. Alternative pricing mechanisms including initial premium payments combined with premium refund or extra premium options are possible for all vehicle classes. Insurers may refund part of

the premium paid for a third-party policy during or after the period for which the policy
is issued by reference to digital information recorded about the safe driving of the
insured vehicle during that period or other factors including the distance travelled. If
insurers wish to apply these refund provisions to any vehicle class the basis and

methodology must be approved by SIRA.

Except for the first MAI Act filing where there is a significant change to an insurer’s


bonus malus structure or change in the bonus malus applied to a group of policyholders
(more than 10% change in the bonus malus percentage applied compared to the
current rating structure in force, in absolute terms), an insurer must include in their

filing:

analysis showing the technical relativity (or cost) for each group of policyholders within the rating factor for which bonus malus changes are proposed
comparison of the technical relativity (or cost) against the actual premium relativity or bonus malus percentage (or cost) proposed.

Except for the first MAI Act filing where an insurer proposes a rating structure that is significantly different from the technical basis, reasons for the difference must be discussed in the filing report.

The various levels of the bonus malus filed by a licensed insurer for each vehicle class and rating region must be supported by experience-based evidence or a reasoned assessment of risk and/or strategic commercial reasons except where an absolute bonus malus has been mandated by SIRA. An insurer must not charge the maximum

State Insurance Regulatory Authority 9

Published LW 17 August 2017 (2017 No 403)

malus for all vehicles in a particular vehicle classification unless this is supported by

such evidence or assessment.

8.6 Malus limits

The maximum malus percentage may be calculated exactly or may be rounded to the nearest one tenth of a per cent. For example, a multiple calculated as 51.2657 per cent may either be applied without rounding or may be rounded to 51.3 per cent.

Premiums charged by an insurer must be no greater than the following multiple of the insurer’s base premium excluding GST for the vehicle classification and each region:

Vehicle Classes Maximum Malus
1 (excluding new7 non-fleet class 1 vehicles), (145% x RB + (IB – RB) x 30%)/IB
3c, 3d, 3e, 5, 6a, 6b, 6c, 8, 9a, 9d, 9e, 9f, 11, 12a,
13 and 18a

7

Not more than 125 per cent of the insurer’s base premium excluding GST

10d, 10e, 10f, 10g and 10h (130% x RB + (IB – RB) x 30%)/IB

6d, 6e, 12b, 14, 15a, 15c, 17, 18b, 18c and 21

Not more than 110 per cent of the insurer’s base premium excluding GST

where

IB = insurer’s filed base premium for a Class 1 Metro vehicle for which the policyholder is not entitled to any ITC

RB = reference base rate at the time of filing.

8.7 Bonus limits

Premiums charged by an insurer for specific vehicle classifications by region must accord with the following if the:

vehicle is a new [8](non- fleet[9]) class 1 vehicle; premiums must be 80 per cent of the base premium excluding GST for each region. No other bonus malus may be charged.

Otherwise for non-new class 1 vehicles and any class 3c vehicles that are not part of a fleet if the:

Published LW 17 August 2017 (2017 No 403)

vehicle is class 1 or 3c and youngest driver is aged under 55, the minimum premium is no less than 80 per cent of the insurer’s base premium excluding GST for these vehicle classifications by region, or

vehicle is class 1 or 3c and the youngest driver is aged 55 or over, the minimum premium is no less than 75 per cent of the insurer’s base premium excluding GST for these vehicle classes by region.

Otherwise for fleet vehicles if the:

fleet comprises 5,000 or more class 1 and/or class 3c vehicles owned by a single entity/operator, or a group of related entities/operators, that proposes to insure third-party policies with one licensed insurer, the minimum premium is no less than
60 per cent of the insurer’s base premium excluding GST for these vehicle classes
by region.

Premiums charged by an insurer for vehicle classes 10d, 10e, 10f, 10g and 10h must be no less than 80 per cent of the insurer’s base premium excluding GST for these vehicle classifications by region.

Premiums charged by an insurer for vehicle classes 3d, 3e, 5, 6a, 6b, 6c, 8, 9a, 9d, 9e, 9f,
11, 12a, 13 and 18a for each region must be no less than 70 per cent of the insurer’s base
premium excluding GST for the vehicle classification by region:

Premiums charged by an insurer for vehicle classes 6d, 6e, 12b, 14, 15a, 15c, 17, 18b, 18c and 21 for each region must be:

No less than 90 per cent of the insurer’s base premium excluding GST for each of these vehicle classes by region

Premiums charged by an insurer for vehicle class 7 must be no less than 80 per cent of the insurer’s base premium excluding GST

8.8 Premiums where entitlement to an Input Tax Credit
(ITC) is applicable

Specific premiums apply when the vehicle owner is entitled to an ITC for GST purposes to allow for the tax treatment. The insurer will determine two sets of premium rates:

(1) nil ITC premium rates applicable to policyholders with no entitlement to any ITC for
GST included in the premium, and

(2) some ITC premium rates, which apply to policyholders entitled to claim an ITC for at least some of the GST included in the premium. Some ITC premium rates will be the insurer’s corresponding nil ITC premium rates increased by a loading.

each insurer will determine the percentage loading it considers appropriate. However, the loading, expressed as a percentage of the corresponding nil ITC premium rates, must be within the range from 6.5 per cent to 7.5 per cent.

the loading will be determined in relation to the effect of policyholders’ entitlement to claim an ITC on the insurer’s entitlement to claim decreasing adjustments for claims costs attributable to those policyholders.

State Insurance Regulatory Authority 11

Published LW 17 August 2017 (2017 No 403)

the ITC loading will be the same percentage for each vehicle classification and region and will not vary according to the bonus malus; that is, the risk rating factors used to determine the bonus malus must be the same for the insurer’s nil ITC premium rates and its ITC premium rates. However, minor variations in the percentage loading attributable only to the calculation of premiums for non- annual policies, or to rounding, are acceptable.

8.9 Loading of premiums for short term policies

For quarterly or six-month policies, short term insurer premiums may include a surcharge (the short term policy surcharge) excluding GST, LTCS levy and MAF levy which is calculated as:

Quarterly premium = (Annual premium + X) x (100% + Y%) / 4

Half yearly premium = (Annual premium + A) x (100% + B%) / 2

Where:

Annual premium excludes GST, LTCS levy and MAF levy
X, Y, A and B are amounts that each insurer will determine subject to:
- X (an administrative costs loading for quarterly policies) being no more than $15
- Y (a forgone investment income loading for quarterly policies) being no more
than 2.2 per cent
- A (administrative costs loading for half yearly policies) being no more than $5
- B (forgone investment income loading for half yearly policies) being no more
than 1.5 per cent.

Each licensed insurer must set one proposed rate for each of the factors X, Y, A and B that will be applied consistently across all short term CTP policies offered by that insurer. The proposed loadings will be included in all filings and must be approved by SIRA. The surcharge does not apply to short term periods for common due date policies. GST and pro rata Fund levy for the relevant policy term are then added to calculate the total amount payable by the policyholder for a short term policy, initially to the nearest one cent.

8.10 Schedule B

A licensed insurer must provide its complete rating structure, risk rating factors and filed premium[10] at each bonus malus level for each vehicle class, rating region and input tax entitlement level, in an electronic spreadsheet designated Schedule B.

Published LW 17 August 2017 (2017 No 403)

9. Justifying third-party premium

assumptions

Insurers must specify how they have determined proposed premiums and must explain the proposed premiums to the satisfaction of SIRA. Insurers are required to complete the published SIRA Motor Accident Filing Template and Appendices.

9.1 Basis of estimate

The total estimated claims cost (risk premium) adopted in the filing must

reflect the expected outcomes of the MAI Act 2017

be on a central estimate basis; that is, an estimate of the mean which must not be intentionally or knowingly conservative or optimistic.

Expense assumptions adopted in the filing must be set with reference to:

maximum rates of expense assumptions specified by SIRA

excluding expenses not directly relevant to the acquisition, policy administration or claims management of third-party insurance business of the insurer

the suitability of expense type for inclusion in a compulsory insurance product and efficiency of insurer’s own administration and claims processes

insurer’s best estimate of expenses taking into account current internal management budgets and internal strategies to control costs.

9.2 Level of explanation

Filed assumptions for full and partial filings must be explained with sufficient information that an analysis of the filing can lead to a conclusion that the results stated in the filing:

have been determined on a central or best estimate basis where required
meet the adequate test under section 2.22 (1) (a) of the MAI Act, and
represent a genuine effort on the part of the insurer to offer competitive premiums and thereby allow SIRA to form an opinion under section 2.22 (1) (a) of the MAI Act that the filed premium is adequate and not excessive.

The level of detail to be provided will depend on the price impact of the assumptions, the extent of the uncertainty surrounding the assumptions, the nature of the analysis and considerations of materiality[11].

9.3 Insurance liability valuation report

Each licensed insurer must provide SIRA with a copy of its latest[12] full valuation report (when it is completed, and including all appendices) relating to its NSW CTP business. Comparison and explanation of any differences between the filed assumptions and the

Published LW 17 August 2017 (2017 No 403)

following assumptions from an insurer’s NSW CTP portfolio Insurance Liability

Valuation Report assumptions must be provided in filings:

claim frequency assumed for premium liabilities13
average claim size assumed for premium liabilities
superimposed inflation
economic assumptions
claim handling expense assumed for premium liabilities13
policy and administration expense assumed for premium liabilities13.

Insurers must explain any developments in experience since the most recent full valuation as part of this comparison.

9.4 CTP business plan and management accounts

Each licensed insurer must provide SIRA annually with a copy of its current NSW CTP business plan and disclose all relevant business and distribution strategies when significant changes are made. Each licensed insurer must provide SIRA with a copy of its NSW CTP management accounts. In addition the insurer must provide a:

comparison of budgeted expenses and actual expenses for the previous filing period
detailed budget of expenses covering the proposed filing period.

For the 1 December 2017 Rate Filing, insurers must provide a detailed expense budget for the policy year 1 December 2017 to 30 November 2018.

The above expense analysis should show the following expenses separately (to the extent they have been broken down as such in the management accounts):

• commission

acquisition and policy administration expenses
claims handling expenses

any other expense components itemised in the insurer’s own management accounts.

9.5 Discount rate assumptions

Insurers must use rates of discount that are no less than the risk-free rates based on the forward rates implied from market information available at the time of preparing the filing, being applied to the average underwriting date of the period filed.

Insurers must disclose the single weighted average discount rate calculated by applying
the payment pattern or expected weighted mean term for the claim liabilities
underlying the policies to be underwritten to the insurer’s adopted rates of discount.
Published LW 17 August 2017 (2017 No 403)
9.6 Maximum rates of assumptions used in the
determination of premiums

SIRA is not bound by the any of the maximum rates of assumptions if it considers that it would be unreasonable to be applied in the particular circumstances of the case. SIRA’s intention in setting maximum rates of assumptions is that they reflect current market

conditions. Alignment to changing market conditions will be considered through
periodical reviews. The following assumptions are subject to a maximum rate used in

the determination of premiums:

claims handling expense assumptions must not exceed a rate of 7.5 per cent of risk premium

acquisition and policy handling expenses including commission and other remuneration are subject to a maximum rate of $43.60 per policy (on average across the policies underwritten by an insurer), indexed with movement in CPI

the superimposed inflation assumption must not exceed a rate of 2.5 per cent

the maximum profit margin for determination of premiums is 8 per cent of the proposed average gross premium (excluding levies and GST)

These maximum rates will be reviewed periodically by SIRA.

Insurers may take into account allowances for innovation and efficiency that are forecast to improve scheme and policyholder outcomes to justify any assumption exceeding the maximum rates of assumptions currently prescribed by SIRA. For the avoidance of doubt SIRA may still reject the premium by an insurer notwithstanding compliance with this clause.

9.7 Risk equalisation mechanism (REM)

In determining proposed premiums the insurer must consider any risk equalisation arrangements that the regulations may impose under section 2.24 (2) of the MAI Act or in accordance with section 2.24 (7) of the MAI Act.

9.8 Calculating net REM amount

Insurers must calculate the net REM amount consistent with the SIRA Motor Accident
Filing Template and Appendices (Schedule D) related to the filing period by:

1.     Projecting the number of annualised policies to be issued for the filing period by each REM pool and for the total of other classes and regions which are not part of the REM pools.

2.     Multiplying the projected number of annualised policies for the filing period in 1) above by the REM $ amount for each REM pool prescribed by the Risk Equalisation Mechanism Deed.

3.     The sum of all the REM amounts for all REM pools from 2) above divided by the projected number of annualised policies for all classes and regions (including those not in REM pool) for the filing period.

4.    This result is the net REM amount per policy that is included in item 12 (a) of Schedule C.

State Insurance Regulatory Authority 15

Published LW 17 August 2017 (2017 No 403)

9.9 Portfolio analysis

Insurers must provide a portfolio analysis consistent with the format detailed in the analysis relating to portfolio mix must be provided:

expected future number and mix of insured vehicles by vehicle class and rating region at each bonus malus level, including commentary on strategies that are expected to result in any changed mix of business
actual past number and mix of insured vehicles for the previous 12 months (for a period ending no earlier than 2 months before the rate filing is submitted), by vehicle class and rating region at each bonus malus level that applied for each policy written within that 12 month period
for each REM pool compare the projected mix of business from the last filing against actual mix including a detailed explanation of any variation of projected mix from recent experience
the net impact of the REM based on the projected mix
proposed use of bonus malus, the basis on which they will be offered to all vehicle owners including a complete description of the rating structure, each rating factor with relevant qualifying time periods, where applicable, definitions of generic
terminology, a summary of the explicit changes in bonus malus since the previous
filing and the impact on the insurer's required and expected average premium

for all policyholders to be issued a renewal notice during the proposed filing increase/decrease (including Fund levy and GST) using incremental bands[15] compared to the actual premium paid for in force policies for each of the following vehicle classes (in Excel format):

- Class 1 by rating region
- Class 3c by rating region

- Class 3d - Class 3e - Class 6a

- Class 7 by plate type
- Classes 10d, 10e, 10f, 10g and 10h combined
- Classes 6d, 6e, 12b, 14, 15a, 15c, 17, 18b, 18c and 21 combined
- All remaining classes combined
- All classes combined in aggregate
expected number of policies by underwriting quarter split by vehicle class, region, ITC entitlement, policy duration and at each bonus malus level with premium income split by insurer premium, MAF levy, LTCS levy, MAITC levy, GST and total payable (in Excel format), and
the resulting average bonus malus factor for each vehicle class and rating region (in Excel format).

9.10 Sensitivity analysis

Except for the first MAI Act filing, insurers must undertake sensitivity analysis on key assumptions that are subject to significant uncertainty to quantitatively illustrate the impact of uncertainty on proposed premiums. Such sensitivity analysis includes the use

of scenarios to test the impact of multiple assumptions simultaneously. reflect an alternate reasonable and plausible situation. Insurers must document the results of the sensitivity analysis in the filing report. Published LW 17 August 2017 (2017 No 403)

SIRA may provide guidance on the specific assumptions or scenarios to be tested and included in a filing prior to its submission.

10.      Full filing report

A full filing report must include the manner in which proposed insurance premiums[16] were determined by the insurer and the factors and assumptions taken into account in the determination of the premiums. This should include discussion and explanation of how the insurer’s assumptions as set out in Schedule E of the SIRA Motor Accident Filing Template and Appendices were derived, and any variation relative to SIRA’s independent actuary.

An explanation of the non-technical pricing factors must also be included where applicable.

The filing report must include the covering letter and commentary on the techniques used in assessing the following items:

Claim frequency

projected future frequency of
- claims for the industry (inclusive of nominal defendant claims), and by
subdivision as set out in Schedule E)
- claims for the insurer (by subdivision as set out in Schedule E and disclosing
the treatment of shared claims and Nominal Defendant claims)

Average claim size

projected future average claim size of
- claims for the industry (inclusive of nominal defendant claims, and by
subdivision as set out in Schedule E)
- claims for the insurer (by subdivision as set out in Schedule E and including
the estimated net effects of shared and Nominal Defendant claims)

A summary of claim frequency and average claim size (in current values), and resulting
cost per policy, by claim component (including nominal defendant), allowing for sharing
and net of ITCs, should be included in the full filing report. This should reconcile to item
1c in Schedule C for claim frequency, and indicate the adjustment to claim sizes

required to reconcile to item 2b in Schedule C.

Economic and investment assumptions

assumed future rates of wage and price inflation
full yield curve adopted and the single equivalent rate of discount

Published LW 17 August 2017 (2017 No 403)

assumed future claim payment pattern for the underwriting period covered by the filing specifying if the basis is current values, inflated or discounted

Superimposed inflation (SI) assumption

Insurer expenses

average past actual and expected future rates and amounts of
- acquisition and policy handling expenses (excluding commission or other

remuneration) associated with third-party policies with appropriate explanation
provided and a description of the methodology used to allocate overhead

expenses

- commission or other remuneration payments. The commission or other

remuneration percentage paid per policy cannot exceed 5% of the insurance

premium)

- claims handling expenses, including an explanation of what is included in this

item, and a description of the methodology used to allocate overhead expenses

- net cost of reinsurance

disclosure of the above past and expected future expenses on a total pool basis as well as on a cost per policy basis for acquisition and policy expenses, and on a per claim basis for claims handling expense[17]

the expense assumptions used and an explanation of how they relate to the above information

Adjustments to insurer premium to obtain the Class 1 Metro base premium by disclosing a full explanation of the calculation of the:

ratio of the Class 1 Metro premium to the average premium

average bonus malus factor – commentary should be included where the filed average bonus malus factor varies from the average implied by the expected future number and mix of insured vehicles by vehicle class and rating region at each bonus malus level (as provided in the portfolio analysis)

• details of how the short term loading parameters A, B, X and Y were determined.

Appendix A, spreadsheet provided), Schedule D and Schedule E (shown in Appendix

A full filing report must include Schedule A, Schedule B, Schedule C (shown in filing report.

10.1 Comparison with previous full filing

Except for the first MAI Act filing, insurers must provide a comparison with the previous full filing of the filed average premium and the actual average premium received by the insurer, together with an explanation of the allowance made for non-annual policies in

calculating these average amounts, including:
how the assumptions regarding future experience in the current premium filing differ from the corresponding assumptions in the previous full filing by the insurer, and
the changes in assumptions and the effect of those changes on the proposed premiums, including reconciliation between the previous and proposed new base premium for a Sydney passenger vehicle for which the policyholder is not entitled to any ITC.
