Discretionary mutuals: the method of sharing costs differs, the annual cycle does not

Discretionary mutuals differ most in how they divide the annual cost among members, and much less in everything else they do each year. That difference should shape how they are run and how the systems behind them are built. The allocation method belongs to each mutual’s board and actuary. The rest of the year, from setting up the renewal to issuing invoices, follows the same steps at almost every mutual, and should be standard.

The second point is less often made. The main constraint on a mutual today is the quality of the information it collects from members. Insurers, reinsurers and regulators all want better data, and members are often volunteers filling in forms once a year. A mutual that collects good information cheaply can buy better reinsurance, answer a regulator quickly and price its members more fairly. A mutual that cannot will find those things harder each year.

How a managed discretionary mutual works

A discretionary mutual fund pools its members’ contributions, pays claims at the board’s discretion, and buys reinsurance for losses above what the pool keeps. At least 28 operate in Australia, and the model has grown over the last decade among small businesses and not-for-profits (Insurance News, May 2026).

Structure. Most are companies limited by guarantee, usually with one vote per member. They hold an Australian Financial Services licence but sit outside the Insurance Act and the Insurance Contracts Act (ASBFEO, 2021). Members usually come from one sector: universities (Unimutual, 52 members in 2015), Victorian and Tasmanian councils (MAV Liability Mutual Insurance), automotive businesses (Capricorn Mutual), and faith, housing and hospitality organisations.

The manager. A professional manager or broker usually runs the mutual day to day (Treasury, 2005). The board keeps the discretion over claims and sets the total to collect. The manager collects member information, applies the rates, issues documents and invoices, places reinsurance and reports to the board, the actuary and the reinsurers. Most of what a member experiences each year is the manager’s work.

Risk layers. The pool pays claims up to a set retention, per claim or in total for the year. Reinsurers pay above that, through excess of loss, quota share or catastrophe cover. A new mutual may reinsure around 90% of its risk and keep more as its reserves grow (ASBFEO, 2021). Large schemes can carry substantial limits: MAV’s scheme carries limits up to $600 million.

The total to collect. The amount is built up from four parts: the reinsurance cost, the claims the pool expects to pay (usually set by an actuary), management and claims handling fees, and compliance costs. Money not used for claims stays in the pool to hold contributions down, or is returned to members. Capricorn, for example, returns surplus to members who paid all their contributions and targets a 75% sufficiency level on actuarial valuation.

Where mutuals differ: dividing the cost

Once the total is set, each mutual divides it among members in its own way. Three examples show how wide the range is:

Capricorn Mutual sets each member’s contribution using location, claims history, size, turnover or payroll, property value and condition, and the limits and excess chosen.
A faith-sector mutual divides a portfolio total by state, then by each member’s exposure within that state.
Shipping mutuals (P&I clubs) apply one board-set increase to every member’s rate, for example 10% for 2023, with extra loadings for members with poor claims records (UK P&I Club).

These methods reflect choices each board has made about fairness, cross-subsidy and how much detail it can collect. They are part of how a mutual governs itself, and they should stay with the board and its actuary, usually in their own model.

This has a practical consequence. A manager or a system that tries to build every mutual’s allocation method into its own software will spend most of its effort on the part that varies most and is least its business. The better arrangement is for the mutual’s model to produce a rate sheet, and for the system to hold that rate sheet with a date and version, apply it to every member, and show how each result was reached. The board keeps control of the method, and every contribution can be traced back to the rates that produced it.

Where they are the same: the annual cycle

Many mutuals renew all members on one date: 30 September for some Australian schemes, 20 February for the P&I clubs. Member information is collected in the months before. The board or actuary sets the total and the rates, every member is rated, and schedules and invoices go out together. Because cover is discretionary, renewal is not automatic; Capricorn tells each member in writing whether it is offering renewal.

The cycle has five main steps:

Set up the renewal year. One record holds everything that applies to that year: the pool’s retention and reinsurance layers, the insurer and terms for any lines placed in the open market, the lines of cover and wordings, which lines are optional, the questions, fees and key dates. It is copied from last year, changed where needed, and locked once issued.
Collect member information. One declaration covers all lines, with each question asked once and used wherever it is needed. Forms are filled in from last year so members change only what is different. Requests go out on set dates, with reminders and a list of who has not replied.
Rate every member. Declarations wait until the year’s rates are loaded. A trial run is checked against the target total, exceptions are reviewed, and the whole batch is approved.
Send everything. Schedules and certificates go to every member at once, with a record of what each member was sent and when.
Invoice. One invoice per member across all lines, with mutual contributions shown apart from any insurance premiums, passed to the accounting system.

Around these sit changes during the year (assets and vehicles added or removed), claims, and reporting. Steps 3 and 4 work on all members at once, and step 2 should too. This is the part of a mutual’s year that is common across sectors, and where standard processes and systems save most effort.

In practice, many mutuals still run this cycle across several systems, with figures re-keyed from one to the next and a spreadsheet that one person understands. Every re-key is a chance for an error, such as a figure ten times too high or too low, to reach a member’s invoice. A standard cycle with checks at each step reduces that risk and the dependence on one person.

Data quality is the real constraint

Of all the steps, collecting member information is the hardest, and it limits what a mutual can do with the rest. The faith sector shows why. After Catholic Church Insurance went into run-off in 2023, insurers returned to faith-based organisations, but they now want better information: asset valuations, governance records and safeguarding records (Insurance Business, Sep 2026). The same applies to the reinsurers behind a mutual. A reinsurer pricing a retention or a catastrophe layer prices on the data it is given.

The people supplying that data are often volunteers: a parish treasurer, a club secretary, a committee member. They complete a declaration once a year, often from scratch, and frequently ask the manager’s staff to complete it for them. Errors and gaps are found late, when the rating is done or when a claim is made.

The practical response is not more questions. It is fewer, better questions, each asked once and used for every line that needs it; forms filled in from last year; checks on ranges and on changes from last year as answers are entered; property and vehicle lists taken as spreadsheets; and sign-off by a named officer. These steps cost little and improve every later stage. For a mutual deciding where to spend money on its operations, structured and checked data collection will usually return more than further work on pricing.

Regulation: light today, but data has been required before

Discretionary mutuals are lightly regulated today. That should not be read as permanent.

Licensing. A mutual needs an AFS licence but sits outside the Insurance Act and the Insurance Contracts Act. The board’s discretion and members’ obligations are set out in the protection wording, so a mutual should record each claims decision and the reasons for it, not only the terms of cover (ASBFEO, 2021). Capricorn gives members a right to take a claims decision to the board.
Past reporting to APRA. From 2008 until October 2016, APRA collected financial data from discretionary mutuals, including contributions by state, claims by class, outstanding claims and financial statements (APRA; Insurance News, 2013).
Capital and reform. A 2019 amendment to the Corporations Act widened mutuals’ access to capital. Further reform was raised at the 2026 parliamentary inquiry into small business insurance (Insurance News, May 2026).

The lesson for a mutual is simple. If it keeps contributions and claims by line, by state and by member, it can produce a regulator’s return when asked, whatever form that return takes. If it keeps them only as invoice totals and a claims handler’s spreadsheet, it cannot. A record of discretionary decisions and their reasons is also the best answer to the criticism that discretion leaves members uncertain.

One question is often left open: how GST and stamp duty apply to mutual contributions compared with insurance premiums, and how each should appear on a member’s invoice. It affects every invoice, and a mutual should take advice on it rather than copy its insurance practice.

The same shape in association schemes

An association scheme placed by a broker under a binder has the same shape as a mutual: one programme, many members, common terms and one renewal date. NSW Athletics is an example. Its broker, Gow Gates, runs a national programme that covers affiliated clubs, members and accredited coaches, and clubs download each season’s certificate of currency online (NSW Athletics). Associations that arrange cover in this way can rely on ASIC’s group purchasing bodies relief instead of holding a licence, provided they do not issue products and give only general information (ASIC Instrument 2018/751).

	Discretionary mutual	Association scheme under a broker binder
Who carries the risk	The pool up to its retention; reinsurers above	The insurer
Who holds authority	The mutual’s board, through its manager	The broker, within the binder
How price is set	A total divided among members by the mutual’s own method	The insurer’s rates, often per member or per head
Claims	Paid at the board’s discretion	A contract under the Insurance Contracts Act
Member data	Detailed exposure: assets, staff, revenue, claims	Often a headcount or registration list
Main outputs	Schedule and one invoice per member	Certificate of currency per club or member

The legal basis differs, but the annual work does not. Both need a renewal-year record, a way to collect member information, rating of every member in one run, and documents issued to every member at once. Associations add a few needs of their own: taking the member list from the association’s registration system, issuing certificates of currency at scale, reporting back to the association, and meeting disclosure obligations where individual members are retail clients.

For managers, brokers and capacity providers, this means the processes and systems built for one can serve the other. A broker running affinity schemes and a manager running mutuals face the same operational problem.

What this means for boards, managers and capacity providers

For boards. Keep the allocation method in your own model and own it. Ask your manager for a rate sheet you can check, a trial run reconciled to the target total, and a list of exceptions before invoices go out. Make sure every claims decision is recorded with its reasons.

For managers. Standardise the cycle and leave the allocation to the board. The work that sets one manager apart from another is not a pricing engine; it is collecting good information from volunteers with little effort, rating and issuing to every member without re-keying, and being able to answer the board, the actuary, a reinsurer or a regulator from the same records.

For reinsurers and insurers. The mutuals worth supporting are the ones that can show contributions and claims by line, state and member, and explain how their rates were set. Ask for that data. Mutuals that can provide it will be easier to price and to renew.

For mutuals not yet formed. A group considering a mutual should ask two questions early: whether its members can supply the information a reinsurer will want, and whether the annual cycle can be run without depending on one person and one spreadsheet. If the answer to both is yes, the remaining questions are about capital and scale.

Discretionary mutuals have operated for a long time and are growing. Their strength is that members choose how to share costs among themselves. Their weakness is often the administration around that choice. Treating the annual cycle as common work, and the allocation as the board’s own decision, addresses that weakness without giving up the strength.
