Participating Fund Singapore: Where Your Whole Life Policy’s Bonuses Actually Come From
The pooled fund behind every non-guaranteed bonus on a par insurance policy
A participating fund (par fund) is a pooled fund an insurer maintains to back its participating life insurance policies — such as whole life and endowment plans — from which it pays guaranteed benefits and declares non-guaranteed bonuses to policyholders based on the fund’s actual investment, claims, and expense experience.

- Premiums from all participating policyholders of a given insurer are pooled into one participating fund, which is invested across a mix of bonds, equities, and other assets to generate returns over the long term.
- MAS regulations require Singapore insurers to distribute at least 90% of the participating fund’s distributable surplus to policyholders, with the insurer (shareholders) keeping no more than 10%, commonly called the 90/10 rule.
- Bonuses declared from the participating fund are non-guaranteed and can vary year to year, or even be reduced, based on the fund’s actual performance relative to projections.
- The fund’s performance depends on three main factors: investment returns, mortality/claims experience (fewer claims than expected is favourable), and expense experience (lower costs than expected is favourable).
- Each insurer runs its own separate participating fund, so bonus rates and historical performance can differ meaningfully between insurers, even for similar policy types.
What Is Participating Fund?
A participating fund is the financial engine behind every “par” life insurance policy — the common whole life and endowment plans sold across Singapore that combine life protection with a savings or investment component. When a policyholder pays premiums into a par policy, a portion goes toward the pure cost of insurance protection and administrative expenses, while another portion is invested within the insurer’s participating fund, pooled together with premiums from all other par policyholders of that insurer.
Because the fund is pooled across potentially hundreds of thousands of policyholders and invested over long time horizons, it can access a diversified mix of assets — bonds, equities, property, and other instruments — that an individual policyholder likely couldn’t replicate alone. The fund’s actual performance over time, smoothed across good and bad years, determines how much the insurer can declare in non-guaranteed bonuses to policyholders.
How It Works in Singapore
Each year (or at other declared intervals), the insurer assesses the participating fund’s performance across three main levers:
| Source of surplus/deficit | Description |
|---|---|
| Investment experience | Actual investment returns compared to what was originally assumed when pricing the policies |
| Mortality/claims experience | Actual death and other claims compared to assumed rates — fewer claims than expected is favourable to the fund |
| Expense experience | Actual operating costs versus assumed costs when the policy was priced |
Under MAS regulations, Singapore insurers running participating funds must allocate at least 90% of the fund’s distributable surplus to policyholders (through bonuses), with no more than 10% going to the insurer’s shareholders — the well-known “90/10 rule.” Insurers typically use a smoothing approach, holding back some surplus in good years to support bonus declarations in weaker years, rather than passing through full volatility year to year.
Bonuses are usually split into reversionary (annual) bonuses, which once declared and vested generally cannot be taken away, and terminal bonuses, which are only confirmed at claim, surrender, or maturity and can vary more significantly based on the fund’s performance at that specific point in time.
Participating Fund Example
An insurer’s participating fund earns stronger-than-expected equity returns and experiences lower-than-assumed mortality claims over a policy year. The fund posts a healthy surplus. Following the 90/10 rule, at least 90% of that distributable surplus is allocated to policyholders through bonus declarations, while the insurer retains up to 10% as its profit share.
A policyholder holding a 20-year endowment plan sees her projected non-guaranteed bonus for that year come in close to the “illustrated” rate shown at the time she bought the policy. In a different year, if the fund underperforms — say during a sharp equity market downturn — the insurer may declare a lower bonus rate, or in severe cases, no bonus at all for that year, since the bonus is explicitly non-guaranteed.
Advantages
- Access to a professionally managed, diversified fund. Policyholders benefit from institutional-scale investing and risk pooling they could not easily achieve individually.
- Smoothing reduces visible year-to-year volatility. Insurers typically hold back surplus in strong years to support bonuses in weaker years, giving policyholders a steadier experience than raw market returns.
- Regulated minimum policyholder share. The 90/10 rule ensures the bulk of the fund’s distributable surplus goes to policyholders rather than the insurer’s shareholders.
- Mortality and expense gains also benefit policyholders. Favourable claims or cost experience, not just investment returns, can support stronger bonus declarations.
Risks and Limitations
- Bonuses are explicitly non-guaranteed. Declared bonus rates can be reduced, or in a bad year, withheld entirely, meaning actual returns can fall well short of the “illustrated” projections shown at the point of sale.
- Opaque to individual policyholders. It can be difficult for an individual policyholder to independently verify or benchmark how well a specific insurer’s participating fund is actually performing.
- Smoothing can mask underlying weakness. A fund that has been underperforming for several years may continue paying similar bonus rates for a period before eventually adjusting downward.
- Fund performance varies significantly between insurers. Two seemingly similar whole life policies from different insurers can have meaningfully different bonus histories, depending on each insurer’s own participating fund experience.
Guaranteed Cash Value vs Non-Guaranteed Bonus (from the Participating Fund)
| Feature | Participating Fund Singapore | Non-Guaranteed Bonus (from the Participating Fund) |
|---|---|---|
| Source | Contractually fixed in the policy from inception | Declared periodically from the participating fund’s actual surplus |
| Certainty | Guaranteed regardless of fund performance | Can vary, be reduced, or in rare cases be zero in a given year |
| Shown in benefit illustration as | Guaranteed column | Non-guaranteed / illustrated column |
| Depends on insurer’s investment skill? | No | Yes, directly |
| Smoothing applied? | Not applicable | Yes, typically smoothed across good and bad years |
The Bottom Line
The participating fund is the quiet machinery behind every whole life or endowment policy’s bonus — a large, pooled, professionally managed fund whose actual investment, mortality, and expense performance determines what policyholders ultimately receive beyond the guaranteed minimum. Understanding that bonuses are genuinely non-guaranteed, and checking an insurer’s historical bonus track record rather than only the illustrated projections, is an important part of evaluating any par policy before buying.

Frequently Asked Questions
What is the 90/10 rule for participating funds?
It is a MAS regulatory requirement that at least 90% of a participating fund’s distributable surplus must be allocated to policyholders through bonuses, with the insurer’s shareholders receiving no more than 10%.
Can my bonus be reduced after it has been declared?
Reversionary bonuses, once declared and vested, generally cannot be taken away, but terminal bonuses — confirmed only at claim, surrender or maturity — can vary and are not locked in until that point.
Why do different insurers offer different bonus rates on similar policies?
Each insurer manages its own separate participating fund, with its own investment strategy, claims experience, and expense structure, so bonus performance can differ meaningfully even between similar-looking policies.
Is my premium entirely invested in the participating fund?
No, a portion of each premium covers the cost of insurance protection and administrative expenses, while the remaining portion is what gets invested within the participating fund.
How can I check an insurer's participating fund performance?
Singapore insurers are required to publish annual participating fund bonus updates and historical fulfillment ratios (how actual bonuses compared to original illustrations), which can be found on the insurer’s website or through your financial adviser.
