2. Definitions

1987 ActWorkers Compensation Act 1987.
1998 ActWorkplace Injury Management and Workers Compensation Act 1998.
AuthorityState Insurance Regulatory Authority (SIRA) constituted under the State Insurance and Care Governance Act 2015.
Basic tariff premiumThe basic tariff premium for an employer is to be calculated by multiplying the wages payable to workers in respect of the period of insurance by the relevant rate as defined by the insurers against the WIC codes.

Where an employer is engaged in more than one business activity and pays wages to workers in more than one class, the proportion of the wages for each class is to be multiplied by the rate applied against each relevant WIC code.

If the policy concerned relates to per capita rates in respect of some or all workers, the relevant numbers by which those rates are to be multiplied (for example the number of boxing matches or taxi licence plate) should be substituted for wages in respect of those workers.
Break-even premium rateThe expected cost for the portfolio divided by wages for the premium renewal year where expected costs include estimated incurred claims costs, investment earnings and expenses, and levies, but exclude profit margin.
Cost of claimsThe claims costs included within the premium formula as per each insurer’s premium filing.
CohortA sub-set of a licenced insurer’s portfolio that exhibits claims experience that is statistically different from other sub-sets. Examples include size (small and large employers) and industry (as defined by the WIC system).
Employer premium rateThe actual premium rate charged for a particular employer. For experience rated employers, the employer premium rate is weighted between the tariff premium rate and their experience premium rate plus any other loadings or adjustments made to the premium.
Licensed insurerAn insurer who holds a current licence granted under Division 3 of Part 7 of the 1987 Act.
Nominal InsurerThe workers compensation Nominal Insurer established by section 154A of the 1987 Act.
Per capita rateThe rate specified for a WIC code that is represented in a way other than a percentage.
Policy or policy of insuranceA policy of insurance as detailed in the 1987 Act.
PortfolioAll workers compensation policies expected to be written in the premium renewal by a licenced insurer.
Premium filingA report of the premiums that the insurer proposes to charge to each employer which includes the formula, parameters and industry premium.
Rating structureA licenced insurer’s methodology for calculating an employer’s workers compensation premium. It will normally consist of formulae, parameters, tariff rates, loadings and discounts.
RegulationsThe Regulations under the 1987 and 1998 Acts respectively.
Specialised insurerAn insurer whose licence is endorsed with a specialised insurer endorsement.
Tariff premium rateThe rate defined for a particular NSW WIC code which reflects the underlying claims cost of a particular industry.
Target premium rateThe total premium expected to be collected for an insurer’s portfolio (including all loadings, discounts and adjustments) divided by total portfolio wages for the premium renewal year.
Ultimate premium rateThe amount as a percentage of wages that is expected to be collected when factors such as capping, safety incentives and other external factors are taken into consideration.
WagesWages as defined in section 174 (9) of the 1987 Act, but does not include a motor vehicle allowance or accommodation allowance to the extent that the allowance is required to be excluded from wages by Annexure D of these Guidelines.
WIC codesThe codes specified in the NSW Workers Compensation Industry Classification (WIC) System (see Annexure A) issued by SIRA as part of the Workers compensation market practice and premiums guidelines.

3. Guideline making power

3.1 These Guidelines are made under section 168 of the 1987 Act.

Section 168 (1) of the 1987 Act allows the Authority to issue guidelines with respect to policies of insurance (the Workers compensation market practice and premiums guidelines).
The Guidelines specify the minimum requirements for policies of insurance as per the 1987 Act and the Regulations and set out how insurers are to present premium filings to the Authority and how the Authority will assess those filings.

4. Scope of guidelines

4.1 These Guidelines form part of a suite of regulatory instruments available to the Authority when regulating insurer financial and prudential arrangements. As per the 1987 Act and the Regulations, the Guidelines specify:

  • the minimum requirements for policies of insurance
  • how insurers are to present premium filings to the Authority, and
  • how the Authority will assess those filings.

4.2 These Guidelines apply to all ‘licensed insurers’ as per the 1987 Act, including the Nominal Insurer and specialised insurers.

To clarify, the following entities are exempt from the requirements outlined in these Guidelines:

4.3 These Guidelines apply to premium filings for policies commencing on or from 4:00pm, 30 June 2017 until the Guidelines are rescinded or replaced.

4.4 Section 3 of the 1998 Act states that the purpose of the workers compensation legislation is to establish a workplace injury management and workers compensation system with the following objectives:

  • to assist in securing the health, safety and welfare of workers and in particular preventing work-related injury
  • to provide:
    • prompt treatment of injuries
    • effective and proactive management of injuries, and
    • necessary medical and vocational rehabilitation following injuries.
  • in order to assist injured workers and to promote their return to work as soon as possible
  • to provide injured workers and their dependents with income support during incapacity, payment for permanent impairment or death, and payment for reasonable treatment and other related expenses
  • to be fair, affordable, and financially viable
  • to ensure contributions by employers are commensurate with the risks faced, taking into account strategies and performance in injury prevention, injury management, and return to work, and
  • to deliver the above objectives efficiently and effectively.

4.5 These Guidelines are aimed at enabling the achievement of these objectives by ensuring insurance policies and premiums are fair, affordable and commensurate with each employer’s risks.

4.6 The Authority will apply these Guidelines in conjunction with relevant legislation, NSW Government policy and other policies and guidelines

5. Premium Principles

Licensed insurer premium filings are required to demonstrate the following principles:

5.1 Principle 1: Premiums are fair and reflective of risk

Employer premiums should be fair and reflective of risk as indicated by the employer’s industry, size and previous claims experience and risk management.

In general, fairness can be assessed relative to other similar cohorts of employers. The intention is that all employers engaged in the same or similar industry or business activities should have premium rates that are the same or similar unless influenced by the individual employer’s previous claims experience and its risk management and return to work practices. Insurers should not deliberately introduce cross subsidies between cohorts of employers.

Where an employer’s previous claims experience is taken into account, the fairness of its premium will be assessed under Principles 2 and 3.

The insurer will need to provide justification that its proposed target average premium rate for a particular cohort fairly reflects the expected claims costs, expenses and suitable profit margin for that cohort.

5.2 Principle 2: Balance between ‘user pays’ and ‘insurance principles’

Employer premiums should strike a reasonable balance between ‘user pays’ (through experience rating) and ‘insurance principles’ (through the pooling of the experience of all employers).

Large employers generally have more influence over their claims experience through risk management and return to work management than small employers. While they need a level of insurance protection through their workers compensation cover (especially for very large claims), they can generally operate according to premiums that are based on their claims experience, ie premiums largely determined on a ‘user pays’ basis.

For small employers, their primary requirement is insurance cover which provides certainty of protection against the costs of workers compensation claims for a fixed premium. Insurers therefore need to pool the premiums for smaller employers so as to spread their claims costs across the premium pool. That is the meaning of ‘insurance principles’ for the purpose of Principle 2.

When dealing with small employers, insurers are required to apply to industry-based rates in accordance with Principle 1, as well as very limited premium adjustments for claims experience and risk management.

As employer size increases, they can take into account the employer’s own claims experience and risk management practices according to their size, whereby the largest employers can be rated almost entirely on their claims experience, return to work management and risk management practices.

5.3 Principle 3: Premiums should not be unreasonably volatile or excessive

This principle builds on the objective that the workers compensation system be fair, affordable, and financially viable.

At a system level, employer premiums should not be excessive. In general, they should be reasonably stable from year to year, fairly reflecting individual employer risk, but at the same time not endangering the financial viability of the system.

Affordability in this context relates to the premium burden on employers in general, and the subsequent impact on the NSW economy.

Protecting employers from excessive and unreasonably volatile premiums is particularly important for small employers. The claims experience of a small employer can be volatile from period to period and can be unduly affected by one large claim.

A small employer’s individual claims experience should not have an unreasonable impact on their premium. From this perspective, small employer premium stability is consistent with the affordability objective in the legislation and the insurance principles articulated in Principle 2.

Large employers have a greater capacity to influence their own claims experience. The fairness of the system is more clearly served if the premiums of larger employers are more directly reflective of their claims experience.

To the extent that financial viability is not unduly impacted (see Principle 5), premium stability includes consideration of the staged implementation of changes to claims experience, premium loadings, discounts and investment earning rates. This will enable employers to adjust injury risk management and return to work practices to mitigate against expected future premium expenses.

5.4 Principle 4: Incentives for risk management and good claims outcomes

Individual premiums should provide incentives for employers to undertake effective risk management aimed at improving health and safety in the workplace and work opportunities for injured employees.

Employers can have their premiums discounted or loaded on the basis of their previous claims experience and the effectiveness of their return to work and risk management practices. Such discounts and loadings, which must also conform to Principles 1, 2 and 3, should be designed (as much as possible) to generate incentives for the employer in the form of premium rebates or reducing future premiums for good or improving performance.

At the same time, perverse incentives or incentives that might compromise the objectives of the scheme in relation to the effective treatment and rehabilitation of injured workers must be avoided.

5.5 Principle 5: The premium basis needs to be consistent with the insurer’s capital requirements

Insurers are required to have a capital management plan that recognises the substantial financial and insurance risks inherent in workers compensation portfolios. An insurer’s premium basis needs to be consistent with its capital management plan and current capital position.

For the Nominal Insurer, the premium rates as a whole are to be set so as to achieve (as far as can be estimated) an overall target premium pool for the year. The target premium pool is to be linked to the Nominal Insurer’s funding plan which will take account of its overall capital management plan, current capital position and target capital position over three forward years.

For each Specialised Insurer, the premium rates as a whole are to be subject to an annual total premium revenue plan that accords with the insurer’s capital management plan.

For those insurers authorised by the Australian Prudential Regulation Authority (APRA), the insurer’s capital management plan is to be presented to the Authority and is required to be consistent with capital management plans that the insurer has submitted to APRA.

For all licensed insurers, the filing is required to justify the difference between:

  • the target premium rate
  • the breakeven premium rate (including cost of claims, expected investment earnings and expenses), and
  • show how this difference impacts on the insurer’s projected capital position.

6. Premium requirements for licensed insurers

6.1 All policies of insurance must comply with Part 7 (Insurance) of the 1987 Act and the Regulations.

6.2 Exemption limit

Section 155AA (8) of the 1987 Act

The exemption limit for the 2017/2018 financial year is fixed at $0 for the following employers:

  • an employer who carries on a business that is covered by Annexure A classes 612310, 612315, 612320, 612322, 612324, 612326, 612330, 931120, 931130, 931930, 931940 or 931950 (being classes that refer to a per capita rate), regardless of whether the employer carries on any other business
  • an employer who carries on a business in the thoroughbred racing industry and who is required by the Rules of Racing (within the meaning of the Thoroughbred Racing Act 1996) to hold a policy of insurance with Racing NSW, regardless of whether the employer carries on any other business.

Fixing the exemption limit for the specified employers at $0 means that those employers will not be exempt employers within the meaning of section 155AA (exempt employers not required to obtain policy of insurance) of the 1987 Act.

6.3 Recovery of excess from employer

Section 160 of 1987 Act

The following prescribed excess amount is specified:

  • $0 – if an employer notifies the relevant licensed insurer of an injury that led to the weekly compensation claim within five days of becoming aware of it
  • in all other cases—the lesser of the following:
    • the amount that is the weekly payment of compensation to which the worker is entitled as determined by section 36 of the 1987 Act
    • the amount as per Annexure B for the applicable policy year.

Under section 160 (2) of the 1987 Act, an employer is required to repay the prescribed excess amount to the insurer under an insurance policy in respect of each weekly compensation claim that the insurer has paid under the policy. However, if the amount that the insurer has paid in respect of any such claim is less than the prescribed excess amount, the amount the employer must repay is that lesser paid amount.

6.4 Late payment prescribed rates

Section 172 (5) of 1987 Act

The prescribed rate is as defined in Annexure C and is the rate applied per month and compounded monthly.

6.5 Mine safety contribution

Mine and Petroleum Site Safety (Cost Recovery) Act 2005

Licensed insurers are required to comply with the provisions of the Mine and Petroleum Site Safety (Cost Recovery) Act 2005 by making the determined contribution to the Mine Safety Fund and advise in the premium filing the rate payable by employers whose wages or a part of their wages are attributable to WIC codes 120000 to 152000.

6.6 Dust diseases contribution

Licensed insurers are required to comply with the Notice published by the Authority and issued pursuant to the Workers Compensation (Dust Diseases) Act 1942, which determines the contributions for insurers under section 6 of that Act.

6.7 Employer definitions

Division 2, section 138 of the Regulations

(a) For the purposes of this Guideline:

Experience-rated employer means an employer whose basic tariff premium for an insurance policy at the time the insurer demands a premium for the policy:

  • exceeds $30,000 (where the period of insurance to which the premium relates is 12 months), or
  • would exceed $30,000 (where the period of insurance to which the premium relates is not 12 months) if that premium was calculated using a period of insurance of 12 months.

Small employer means an employer whose basic tariff premium for an insurance policy at the time the insurer demands a premium for the policy:

  • does not exceed $30,000 (where the period of insurance to which the premium relates is 12 months), or
  • would not exceed $30,000 (where the period of insurance to which the premium relates is not 12 months) if that premium was calculated using a period of insurance of 12 months.

(b) If an employer is a member of a group, a reference to the basic tariff premium of the employer or to total wages payable by the employer to workers (however expressed), is taken to be a reference to the sum of the basic tariff premiums of all members of the group or to total wages payable to workers by all members of the group, respectively.

6.8 Wages and motor vehicle allowances

Section 174 (9) of the 1987 Act

The definitions and calculations regarding the extent to which motor vehicle and accommodation allowances are to be excluded from wages as defined in Annexure D.

  • The claims and basic tariff premium history of an employer’s predecessor must be used in the calculation of the employer’s workers compensation insurance premium.
  • Sub-clause 6.9 (1) applies when the business acquired is the whole or main part of the business of the person, or is the whole or main part of a separate and distinct business of the person, and whether or not the business acquired is carried on at the same location.
  • Sub-clause 6.9 (2) applies whether or not the activities carried out or services performed for the employer were carried out or performed at the same location as those carried out or performed for the person.
  • In this clause, business has the same meaning as in Division 2B of Part 7 of the 1987 Act.
