The Prudential Standard organizes around a few discrete technical and governance concepts. First, operational risk is defined in the standard as the risk of loss resulting from inadequate or failed internal processes, people and systems or from external events within the health insurance business and health related insurance business (s6). The operational risk charge is an explicit, minimum capital buffer set aside to cover that category of risk (Objectives and key requirements; s6).

Second, the ORC calculation is formulaic and combines measures of activity (accrued premium) and balance-sheet risk (insurance liabilities central estimate). The formula, shown in s7, is operationally:

• ORC = 0.02 × max(GP1, NL) + max(|GP1 − GP0| − 0.2 × GP0, 0)

Where GP1 is accrued premium for the 12 months ending on the reporting date, GP0 is accrued premium for the 12 months ending 12 months prior, NL is the central estimate of insurance liabilities net of reinsurance, and the absolute difference captures year-on-year premium volatility (s7). The first term applies a 2 per cent rate to the larger of GP1 and NL. The second term is a floor capturing excessive premium growth, i.e. the positive part of the absolute difference between GP1 and GP0 after subtracting 20 per cent of GP0 (s7).

Third, accrued premium is precisely defined so that the activity measure is not simply premiums received. It equals premiums received less A plus B, where A is the change in premiums in advance over the specified period and B is the change in unpaid premiums over the period. Premiums must include relevant levies, loadings and discounts (s8). The Standard also explicitly includes premiums from both Health Insurance Business and Health Related Insurance Business in accrued premium (s8).

Fourth, the Standard applies at fund level unless otherwise noted. The Prudential Standard directs insurers to apply the Standard separately to each of their health benefits funds and the general fund (s3). The term private health insurer, for the purposes of the instrument, is defined by reference to section 4 of the Act, and APRA is the issuing authority (Interpretation; Authority).

Fifth, APRA retains discretionary supervisory power to adjust or exclude the application of a specific requirement for a particular insurer by written notice (s9). This creates a mechanism for case-by-case regulatory relief or tailoring.

Finally, the Prudential Standard cross-references other prudential instruments. Definitions are those in HPS 001 (s5) and the central estimate of insurance liabilities (NL) must be determined in accordance with HPS 340 (s7(c)). The Standard describes the ORC as a component of the prescribed capital amount (Objectives and key requirements), linking it to the broader capital adequacy framework under the Act (Authority).

The Prudential Standard applies to all private health insurers, save where the Standard expressly notes otherwise, and it applies from 1 July 2023 (s2; s4). The instrument requires application separately to each health benefits fund and to each general fund of a private health insurer, unless otherwise noted (s3). The instrument defines APRA and references the statutory definition of private health insurer in section 4 of the Act (Interpretation; Authority).

Who bears the direct economic burden. The insurers themselves must hold the ORC as a minimum capital amount for each fund (s6-7). That means capital resources must be allocated to meet the ORC at the fund level rather than only at the consolidated insurer level (s3; s6). The source expresses the Board’s responsibility for prudent capital management and for ensuring an adequate level and quality of capital commensurate with the insurer’s scale, nature and complexity (Objectives and key requirements). Therefore, the Board and senior management are the decision-makers within the insurer responsible for ensuring compliance, capital planning, and any consequent changes in asset allocation or capital raising.

How the requirement touches other stakeholders. Because accrued premium includes levies, loadings and discounts (s8(c)), any changes insurers make to product pricing, levy absorption, or discounts will affect the ORC base. Reinsurance affects the calculation asymmetrically: GP1 and GP0 are specified gross of reinsurance while NL is net of reinsurance (s7(a)-(c)). That creates different incentives around the use of reinsurance: the activity measure is unaffected by ceded premium, while the liabilities measure reflects reinsurance arrangements.

APRA decides whether to adjust or exclude specific requirements for an insurer via written notice (s9). This creates a direct regulatory lever affecting covered insurers on a case-by-case basis. The Standard does not explicitly exempt any class of insurers from application; it applies broadly unless APRA exercises s9 discretion.

Operationally, actuaries, finance teams and systems administrators within insurers will be directly engaged in the calculation of GP1, GP0, NL and the underlying accrued premium components A and B (s7-8). Custodians of fund-level accounting and premium-recording processes carry compliance responsibility to ensure that premiums in advance and unpaid premium movements are captured correctly for accrued premium (s8(a)-(b)).

Duties imposed by the Prudential Standard

• Maintain at least the Operational Risk Charge. The core duty is to hold the ORC as the minimum capital required to cover operational risk for the health insurance and health related insurance business of each fund (Objectives and key requirements; s6-7).

• Apply the Standard at the fund level. Unless otherwise noted, insurers must apply the Prudential Standard separately to each health benefits fund and each general fund (s3).

• Calculate the ORC according to the prescribed formula and definitions. The insurer must calculate GP1 and GP0 as accrued premiums for the relevant 12-month periods, compute NL as the central estimate of insurance liabilities in accordance with HPS 340, and apply the mathematical operations in s7 and the accrued premium mechanics in s8.

• Ensure Board oversight. The instrument explicitly states that ultimate responsibility for prudent capital management rests with the Board, which must ensure adequate level and quality of capital commensurate with the scale, nature and complexity of the business and its risk profile (Objectives and key requirements). That places a governance duty on Boards to integrate the ORC into capital planning and reporting frameworks.

Administrative duty to consider APRA notices. APRA may adjust or exclude specific requirements by written notice to an insurer (s9). Insurers therefore have a duty to monitor for and respond to APRA communications under s9.

Rights or procedural entitlements

• No procedural rights are described in the Prudential Standard for private health insurers aside from the availability of APRA discretion in s9. The instrument specifies that APRA may adjust or exclude a specific requirement by written notice to a private health insurer (s9). The Standard does not set out procedures, criteria or timelines for APRA’s exercise of that discretion within the text.

• The Standard does not itself confer express statutory rights to appeal or review; it is an instrument issued under s92(1) of the Act (Authority). The Standard also does not specify transitional relief, reporting formats or approval rights for alternative approaches. Any such rights or procedures would need to be sourced from the Act or other prudential instruments, but are not contained in this Prudential Standard.

Operational duties that follow from the calculation definitions

• Accrued premium accounting. Insurers must record and maintain the components required to compute accrued premium: premiums received inclusive of levies, the change in premiums in advance (A), and the change in unpaid premiums (B) for each specified period (s8).

• Valuation duties for NL. Insurers must determine NL as the central estimate of insurance liabilities net of reinsurance in accordance with Prudential Standard HPS 340 (s7(c)). That places a technical actuarial obligation on insurers to apply HPS 340-compliant processes when deriving NL.

• Application to both Health Insurance Business and Health Related Insurance Business. Accrued premium is required to include premiums from both categories (s8), so insurers that operate in both spaces must aggregate them as specified.

Who decides

• Decision-making inside insurers: Boards and senior management decide capital planning, allocation of capital to satisfy the ORC, and operational arrangements to calculate the ORC (Objectives and key requirements; s3; s6-8).

• Regulatory decision-making: APRA decides whether to vary or exempt specific requirements for a particular insurer by written notice (s9). The Standard does not set substantive criteria for that discretion within the text provided.

This Prudential Standard itself does not specify civil or criminal penalties, nor does it set out enforcement procedures within its text. The instrument states it is made under subsection 92(1) of the Private Health Insurance (Prudential Supervision) Act 2015 (Authority), and it prescribes substantive requirements (for example the ORC formula at s7). However, the document does not contain any provisions that describe sanctions, enforcement remedies, administrative penalties, directions, or supervisory actions for non-compliance.

APRA retains an explicit supervisory lever in the form of discretion to adjust or exclude specific requirements for a given insurer by written notice (s9). That is a form of regulatory intervention that the Prudential Standard makes available to APRA, but the Standard does not describe any enforcement action APRA may take where an insurer fails to meet the ORC.

Because the Standard does not enumerate penalties or enforcement mechanisms, the instrument implicitly relies on the broader statutory framework under which it is made for any enforcement or supervisory powers. The text of the Prudential Standard confines itself to capital requirements, the prescribed calculation method and APRA’s ability to tailor application to particular insurers by written notice (s1; s2-4; s9). The Standard does not set reporting obligations, notification deadlines, or remediation timeframes within its own terms.

Practically, insurers must treat the ORC as a minimum capital component (Objectives and key requirements; s6-7) and integrate it into their capital planning and governance. The absence of explicit penalty clauses in the Standard increases the importance of checking the Act and other prudential instruments for the available enforcement powers and for any supervisory measures APRA may exercise, because enforcement is not detailed in this instrument.

The Prudential Standard expressly situates itself within the existing prudential architecture and cross-references other instruments. The Standard is made under subsection 92(1) of the Private Health Insurance (Prudential Supervision) Act 2015 (Authority). It describes the Operational Risk Charge as one of the components of the prescribed capital amount for private health insurers (Objectives and key requirements), thereby linking the ORC to the broader capital regime established by the Act.

Definitions. The Standard instructs readers that terms defined in Prudential Standard HPS 001 Definitions appear in bold the first time they are used and that those definitions apply (s5). That ties the Standard’s interpretation to the definitions contained in HPS 001.

Valuation. The calculation of NL, the central estimate of insurance liabilities used in the ORC formula, must be determined in accordance with Prudential Standard HPS 340 Insurance Liability Valuation (s7(c)). That creates a dependency: the actuarial and valuation methodology and assumptions required by HPS 340 will directly affect the NL input to the ORC. Any changes in HPS 340 would therefore affect ORC outcomes.

Interaction between gross and net measures. The ORC’s components explicitly treat GP1 and GP0 (accrued premium) as gross of reinsurance and NL as net of reinsurance (s7(a)-(c)). This asymmetry means the ORC combines a gross activity-based measure with a net liability measure. That interaction may mediate the effect of reinsurance arrangements on the ORC and is an intentional linkage in the Standard.

Accounting and premium recording. The accrued premium definition in s8 references premiums received inclusive of relevant levies, loadings and discounts, and requires adjustments for movements in premiums in advance and unpaid premiums. That creates an interaction with insurers’ accounting, premium recognition and revenue systems, which must capture the movements A and B so the ORC can be calculated as prescribed.

Fund-level application. The Standard requires, absent express notation to the contrary, that it be applied separately to each health benefits fund and to the general fund (s3). That interacts with how insurers structure their statutory funds and internal capital allocation. Fund-level prudential capital may differ from consolidated capital, and the Standard affects intra-insurer capital allocation decisions.

APRA discretion. Section 9 allows APRA to adjust or exclude a specific requirement in the Prudential Standard by written notice to a private health insurer (s9). This interactively links the Standard to APRA’s supervisory discretion and case-by-case regulatory engagement.

No explicit interaction clauses. The instrument itself does not cross-reference civil or criminal penal provisions, dispute resolution mechanisms, reporting timelines, or other Acts. It does not set out how it interacts with taxation, general corporate law, insolvency law, or other prudential instruments beyond those referenced. Those interactions will be governed by the broader statutory and regulatory framework, but they are not contained within this Prudential Standard.

This document records its own making and commencement but contains no subsequent amendment history in the text provided. The instrument was determined by a delegate of APRA, Helen Rowell, under subsection 92(1) of the Act and is dated 24 May 2023. The instrument states that it commences on 1 July 2023 (Authority; Application and commencement). The Schedule sets out Prudential Standard HPS 118 and the Standard’s text describes its scope, definitions and mechanics (Schedule; Table of Contents; s1-9).

There are no amendment notes, rescission clauses, or versioning statements in the text supplied. The Standard refers to other prudential instruments (HPS 001 and HPS 340) for definitions and liability valuation, but the text does not indicate any transitional provisions, grandfathering of prior approaches, or prior instruments being replaced. The document’s own metadata in the header identifies it as “Prudential Standard HPS 118 Capital Adequacy: Operational Risk Charge” and includes the declaration that it applies to all private health insurers, except where expressly noted otherwise (s2).

If an insurer requires a modification to the Standard’s application, the mechanism in the Standard is for APRA to issue a written notice adjusting or excluding a specific requirement in relation to that insurer (s9). The Standard contains no internal clause setting out how amendments to HPS 118 itself would be made in the future beyond the fact it is a prudential standard made under subsection 92(1) of the Act (Authority). Any formal amendment history, revocations, or consolidated versions would thus need to be tracked through APRA’s published instrument registers and legislative instruments records external to this document; such records are not included in the text supplied.

The Prudential Standard’s text does not contain or reference any litigation history, court decisions, or administrative determinations. No cases, appeals, or judicial reviews are named or summarised in the instrument. The document is an instrument made under subsection 92(1) of the Act and sets out technical requirements for the Operational Risk Charge, but it does not include statutory or administrative litigation developments.

Because the text itself does not mention any prior challenges or judicial interpretations of HPS 118, there is no litigation history recorded within the provided material. The instrument also does not reference previous disputes about interpretation, nor does it catalogue precedents or prior guidance on contested points such as the formula’s application, the treatment of reinsurance, or fund-level application.

Absent content in this instrument, insurers and advisers must rely on other sources to determine whether any litigation has arisen concerning HPS 118. The Standard contains provisions that could give rise to interpretative questions, for example the interaction between GP1/G P0 being gross of reinsurance and NL being net of reinsurance (s7), or the application of the accrued premium adjustments for premiums in advance and unpaid premiums (s8). The instrument itself, however, provides no record of disputes or court consideration of these issues in the text provided.

This Prudential Standard does include a supervisory discretion (s9) by which APRA may adjust or exclude a specific requirement by written notice to an insurer. That discretion could be relevant to any dispute about equivalence, proportionality or administrative decision-making, but the instrument does not record any legal challenges to the use of that discretion.

Several technical and implementation features of the Prudential Standard may produce unintended operational consequences or points requiring careful attention. The following items derive directly from the Standard’s text and its specified mechanics.

1. Fund-level application increases granularity of capital requirements (s3). The Standard requires application separately to each health benefits fund and the general fund. Insurers that previously managed capital at a consolidated level may need to reallocate capital across funds or hold additional capital to meet per-fund ORC minima. This can affect internal capital efficiency and may require changes to internal capital allocation policies.

2. Mismatch between gross and net measures (s7). GP1 and GP0 are explicitly gross of reinsurance while NL is net of reinsurance (s7(a)-(c)). The formula therefore combines a gross activity base with a net liability measure. Insurers using reinsurance to manage liability risk should note that ceded premium does not reduce the activity base but does reduce the liabilities input. This asymmetry can alter the marginal capital impact of entering into reinsurance contracts.

3. Accrued premium arithmetic requires record-keeping (s8). The accrued premium definition requires adjustments for movements in premiums in advance (A) and unpaid premiums (B). Insurers must ensure accounting systems track opening and closing balances for these items for the specified 12-month reporting periods. Different handling of premium timing and receipt could materially change GP1 and GP0.

4. Inclusion of levies, loadings and discounts (s8(c)). Premiums must be inclusive of relevant levies, loadings and discounts. That means product pricing changes or the application of discounts will feed directly into GP1 and GP0; discounts that reduce premiums received reduce GP1 and therefore can change the ORC.

5. Year-on-year growth backstop (s7). The second term in the formula, max(|GP1 − GP0| − 0.2 × GP0, 0), introduces an additional capital requirement where year-on-year premium changes exceed 20 per cent. This penalises large premium growth or contraction between comparable periods and will generate an incremental capital requirement if the absolute change surpasses the 20 per cent threshold.

6. Relationship to HPS 340 for NL (s7(c)). NL must be calculated as the central estimate of insurance liabilities in accordance with HPS 340. Variations or changes in HPS 340 actuarial methods, assumptions or required margins will affect NL and so feed into the ORC. It creates a dependency on actuarial valuation processes outside the ORC formula.

7. No transition provisions in the Standard text. The Standard commences from 1 July 2023 (Application and commencement), but the instrument contains no explicit transitional relief or grandfathering clauses. Insurers implementing systems and valuation processes must be operational by that date according to the Standard’s text.

8. APRA discretion creates regulatory uncertainty for specific relief (s9). APRA may adjust or exclude specific requirements for an insurer by written notice, but the Standard does not specify the criteria, timing, or processes by which APRA will exercise this power. That leaves some regulatory uncertainty for insurers that may seek tailored treatment.

9. No enforcement or penalty detail in the Standard. The instrument does not specify penalties or enforcement measures (Penalties and enforcement). Insurers should therefore review the underlying Act and related prudential instruments to understand supervisory consequences and enforcement options that could apply for non-compliance.

10. Scope includes health related insurance business (s8). Accrued premium expressly includes premiums from both Health Insurance Business and Health Related Insurance Business. Operators with mixed portfolios must ensure aggregation is performed correctly, which can bring additional operational complexity.

11. Absolute value term requires symmetry. The formula uses |GP1 − GP0|, the absolute value of the difference in accrued premiums, so both large increases and large decreases in premium volumes can trigger the growth-related capital add-on. This may affect insurers experiencing significant premium contraction as well as those with rapid growth.

12. The instrument references HPS 001 for definitions (s5). The Standard unpacks terms by reference to HPS 001, so differences in definition under HPS 001 (for example how funds are defined or reporting date is defined) feed into the correct application of HPS 118.

This section sets out practical, document-grounded steps to calculate the ORC and integrate the Prudential Standard into capital and governance processes. Each step follows from the Standard’s text (s1-9; Objectives and key requirements; s6-8).

1. Establish governance and Board oversight. The Board is identified as ultimately responsible for prudent capital management and ensuring capital adequacy commensurate with scale, nature and complexity of the business (Objectives and key requirements). Boards should ensure the ORC is integrated into capital policies, risk appetites, reporting lines and decision-making fora.

2. Confirm fund-level scope and reporting dates. Apply the Standard separately to each health benefits fund and the general fund (s3). Identify the reporting date for each fund and confirm the 12-month windows that define GP1 and GP0. Ensure financial and actuarial teams are aligned on the applicable reporting dates.

3. Implement or update actuarial processes to determine NL in accordance with HPS 340. The NL input to the ORC must be the central estimate of insurance liabilities net of reinsurance determined under Prudential Standard HPS 340 (s7(c)). Cooperate with the actuary responsible for HPS 340 valuations to provide timely NL figures for the reporting date used in the ORC calculation.

4. Prepare premium accounting and reconciliations for accrued premium. Compute accrued premium as specified in s8:

• Start with premiums received for the specified period inclusive of relevant levies, loadings and discounts (s8(c)).

• Calculate A, the change in premiums in advance: premiums in advance at the end of the specified period minus premiums in advance at the start.

• Calculate B, the change in unpaid premiums: unpaid premiums at the end minus unpaid premiums at the start.

• Apply the arithmetic: Accrued premium = Premiums received − A + B (s8). Document and reconcile opening and closing balances for premiums in advance and unpaid premiums to ensure auditability.

Accrued premium must include premiums from Health Insurance Business and Health Related Insurance Business (s8).

5. Calculate GP1 and GP0. GP1 is accrued premium (gross of reinsurance) for the 12 months ending on the reporting date; GP0 is the accrued premium for the 12 months ending 12 months prior (s7(a)-(b)). Ensure GP1 and GP0 are computed on comparable bases and that any adjustments, levies or discounts are treated consistently.

6. Apply the ORC formula precisely. Using the calculation in s7:

• Compute the first term: 2 per cent (0.02) times the maximum of GP1 and NL.

• Compute the second term: the positive part of the absolute difference between GP1 and GP0 after subtracting 20 per cent of GP0, formally max(|GP1 − GP0| − 0.2 × GP0, 0).

• Sum the two terms to produce ORC.

Keep detailed working papers showing the inputs, rounding conventions, currency basis, and any judgement applied.

7. Address the reinsurance asymmetry. GP1 and GP0 are gross of reinsurance while NL is net. Document the treatment of reinsurance in premium recording and liability valuation so internal and external reviewers can reconcile how reinsurance affects the ORC.

8. Integrate ORC into capital planning and reporting. Treat the ORC as a minimum capital component for each fund and reflect it in capital targets, contingency plans, recovery plans and liquidity planning. Document how capital will be raised, reallocated, or retained to meet the per-fund ORC.

9. Monitor premium volatility. Because the formula includes a year-on-year growth term that triggers above a 20 per cent change, monitor premium volume trends and prepare forecasts that estimate the ORC under plausible premium scenarios. Where significant growth or contraction is projected, quantify the incremental ORC impact and include it in capital stress-testing.

10. Liaise with APRA regarding adjustments or exclusions. If an insurer considers that a specific requirement should be adjusted or excluded for its circumstances, the Standard permits APRA to do so by written notice (s9). Insurers should prepare a dossier of rationale and supporting evidence should they seek a written notice from APRA, and maintain communications records with APRA.

11. Ensure documentation and audit trail. Maintain comprehensive records of all inputs, assumptions, calculations, and internal approvals for the ORC. That includes the accrual adjustments (A and B), detail on what constitutes relevant levies, loadings and discounts, and the HPS 340 actuarial valuation supporting NL.

12. Update systems and control frameworks. Where existing systems do not capture premiums in advance or unpaid premiums at the necessary granularity, implement system changes and control processes to reliably produce the accrued premium inputs at fund level. Ensure reconciliation, exception handling and sign-off processes are in place.

13. Maintain readiness for reporting from 1 July 2023. The Standard applies from 1 July 2023 (Application and commencement). Ensure processes and reporting are operational by that date in accordance with the Standard’s text.

14. Review interconnections with other prudential requirements. Because the ORC is described as a component of the prescribed capital amount (Objectives and key requirements) and depends on HPS 340 for NL and HPS 001 for definitions (s5; s7(c)), coordinate with teams responsible for compliance with those instruments to ensure consistent application.

15. Consider internal policy and product implications. Because accrued premium includes levies, loadings and discounts (s8(c)), pricing decisions and discounting strategies will affect ORC outcomes. Boards and management should consider whether product design, pricing or discounting changes introduce capital impacts under the ORC formula and document the policy rationale.

Following these steps aligns operational practice directly with the Prudential Standard’s text and provides an auditable trail of compliance.
