Average Clause Malaysia: How Underinsurance Cuts Fire and IAR Claims

Here's an uncomfortable market observation that most Malaysian factory owners will never hear from their insurance agent. AIG Malaysia has reported that over 85% of Malaysian SMEs are inadequately covered against fire and property damage.

That protection gap routinely converts into reduced claim payouts when the average clause bites at loss. Not because the loss wasn't covered.

Not because the paperwork was wrong. Purely because the insured set their sum insured too low.

The average clause, also called the condition of adequacy, is a standard term in almost every Malaysian fire insurance and Industrial All Risks (IAR) policy. It reduces your claim proportionally to the degree your sum insured falls short of the full value at risk. And it applies to partial losses, not just total losses.

This guide explains what the average clause is, shows worked examples of how it cuts claims, explains why it applies even when you're claiming less than the sum insured, and lays out how to size your sum insured correctly to avoid the reduction.

What the Average Clause Is and Where It Lives in Your Policy

The average clause is a standard condition in Malaysian fire and IAR policies that says, in effect: "If at the time of loss, the sum insured is less than the full value of the insured property, the insured is considered a co-insurer for the difference and will bear a rateable proportion of the loss."

In plain language: if your sum insured is 60% of the actual value, the insurer will pay 60% of any partial-loss claim. The remaining 40% is your problem.

This applies even if the loss amount is below the sum insured. That's the part most people miss.

The clause sits in the general conditions section of the policy. Quotations don't usually explain it, and the policy schedule doesn't flag it. But it's there, and it's enforceable.

A Worked Example, Illustrative, Not a Specific Case

The best way to understand the clause is to see it applied.

Imagine a factory with an actual reinstatement value of RM10 million (building plus fixtures plus machinery plus stock). The owner insures it for RM6 million, 60% of actual value. A partial-loss fire damages RM2 million worth of property.

The owner submits a RM2 million claim. They reason: "Our sum insured is RM6 million. The loss is RM2 million.

That's well under the sum insured. Claim should be paid in full."

The insurer's calculation is different:

• Adequacy ratio: Sum insured ÷ Full value = RM6m ÷ RM10m = 60%
• Claim payable: Loss amount × Adequacy ratio = RM2m × 60% = RM1.2 million
• Amount owner must absorb: RM2m − RM1.2m = RM0.8 million

The average clause cuts RM800,000 off the claim, even though the loss is well below the sum insured. The owner is a co-insurer for the shortfall.

This example is illustrative, not a specific client case.

Why the Average Clause Exists

Insurance pricing is based on the premium reflecting the full risk. If you insure a RM10 million factory for RM6 million, you're paying premium for 60% of the risk but exposing the insurer to 100% of the partial-loss exposure (because partial losses don't scale down to match your sum insured).

The average clause is the mechanism that aligns premium paid to risk transferred. If the insured wants a lower premium, they accept a proportionally lower claim in the event of partial loss. If they want full cover on partial losses, they have to insure at full value and pay the corresponding premium.

Without the average clause, every insured would be incentivised to insure at a fraction of actual value, paying minimal premium but still collecting full payouts on partial losses. The clause closes that loophole.

Partial Loss vs Total Loss, Why the Clause Hits Harder on Partial Losses

Scenario	Sum Insured	Actual Value	Loss	Claim Paid	Owner Absorbs
Adequately insured, partial loss	RM10m	RM10m	RM2m	RM2m	RM0
60% insured, partial loss	RM6m	RM10m	RM2m	RM1.2m	RM0.8m
50% insured, partial loss	RM5m	RM10m	RM2m	RM1m	RM1m
50% insured, total loss	RM5m	RM10m	RM10m	RM5m (capped at sum insured)	RM5m

In a total loss, the sum insured itself caps the payout, the average clause can't reduce you below the cap, and in some policy versions, the clause doesn't apply to total losses at all. But in a partial loss, the clause actively cuts the claim by the adequacy ratio, even though you'd otherwise have thought you had enough sum insured to cover.

This is counterintuitive. People often think partial losses are "the safe ones" because the loss is below the sum insured. The average clause inverts that intuition.

Why Malaysian Factory Owners End Up Underinsured

Underinsurance isn't usually deliberate. It happens through four common mechanisms.

1. Sum Insured Tied to the Loan Amount

When a factory is financed, the bank requires fire insurance. Borrowers often set the sum insured at the loan amount, which matches what the bank needs to protect its security, but not the actual reinstatement cost. If the reinstatement cost is 1.5× the loan, the owner is 33% underinsured without realising it.

2. Sum Insured Not Reviewed as Asset Value Grows

A factory that installed machinery five years ago at RM5 million worth of equipment may now be running RM8 million of equipment after expansions and upgrades, but the policy schedule still shows RM5 million under machinery. This kind of silent value creep is the single biggest cause of underinsurance on established operations.

3. Stock Insured at Average Rather than Peak

Stock values fluctuate with production and order cycles. Insurers sometimes set stock sums insured at the year-average level, not the seasonal peak. If a fire hits at peak stock, underinsurance bites.

4. Book Value Instead of Replacement Value on Machinery

Accountants depreciate machinery on the books. Insurance should use replacement cost, the cost to buy a new equivalent machine today, not book value, which has been reduced by depreciation. Using book value understates the sum insured and triggers the average clause on claim.

How to Get the Sum Insured Right

Building

Use reinstatement value, the cost to rebuild at current construction prices, including professional fees, demolition, and debris removal. For larger or non-standard buildings, commission a reinstatement-cost estimate from a valuer or quantity surveyor. For simpler buildings, use a per-square-foot benchmark for the construction class, or the insurer's rebuilding cost guide as a starting point.

Machinery and Plant

Use replacement cost new, the price of a new equivalent machine today. Not book value. If the exact model is no longer manufactured, use the closest current equivalent.

Stock in Trade

Use the maximum anticipated stock value during the year. If stock peaks during festive seasons or order cycles, insure to the peak.

Many policies allow stock adjustment declarations, a mechanism where the actual stock value is declared periodically and premium adjusted accordingly. For stock-heavy operations, this is often the cleanest approach.

Professional Fees, Debris Removal, Public Authorities

These are usually set as separate sums insured or percentages of the main sum insured. Typical practice is 10–15% for professional fees and debris removal combined, with separate allowance for Public Authorities (the cost of complying with new building codes during reinstatement). Verify these are adequate for your building type.

The 85% Rule and Other Adequacy Thresholds

Some Malaysian fire policies contain a modified version of the average clause called "85% average condition." Under this wording, the clause only applies if the sum insured falls below 85% of the full value. Between 85% and 100% of value, no average is applied, you're treated as adequately insured.

This is a borrower-friendlier version of the clause, but it's not universal. Standard tariff fire policies in Malaysia typically apply average from the first ringgit of underinsurance. Only specific endorsements or non-tariff products offer the 85% threshold.

Don't assume you have the 85% concession unless it's specifically noted in the policy schedule or endorsement. If it's important to you, ask for it explicitly and verify the endorsement appears on the policy.

Reinstatement Value Conditions, The Upgrade That Sits Above Average

A standard fire policy pays on an indemnity basis: the cost of the damage, less depreciation for wear and tear. For a 10-year-old building or a 5-year-old machine, the indemnity payout is less than the replacement cost because of depreciation.

A reinstatement value condition (sometimes called "new for old") modifies this: the policy pays the full replacement cost, without depreciation deduction, provided the reinstatement actually happens. This is what most commercial and industrial policies in Malaysia use today.

The reinstatement value condition and the average clause interact:

• Reinstatement value raises the benchmark for adequacy. The full value at risk is now replacement cost, not depreciated value.
• If your sum insured is below replacement cost, the average clause still applies, at the higher reinstatement benchmark.
• If your sum insured is at replacement cost, you're adequately insured and average doesn't cut the claim.

Common Mistakes When Setting Sum Insured

Mistake	Consequence	Fix
Using purchase price instead of reinstatement	Land value inflates purchase price; may over or underinsure depending on location	Use reinstatement cost estimate from valuer or QS
Using book value for machinery	Heavy underinsurance after 3–5 years of depreciation	Use replacement cost new
Setting stock at average rather than peak	Underinsured at peak season when loss risk is highest	Use peak value or stock declaration endorsement
Forgetting tenant improvements / fit-out	Fit-out value not insured; fit-out damage uncovered	Include tenant improvements in building sum insured or as separate line item
Ignoring professional fees and debris removal	Reinstatement cost shortfall of 10–15% after a total loss	Add separate sums insured for these items
Not reviewing sum insured annually	Value creep from additions creates silent underinsurance	Annual sum insured review with intermediary at renewal

FAQ

Does the average clause apply to all Malaysian fire policies?

The average clause (condition of adequacy) is standard across Malaysian fire and IAR policies. Some policies include a modified 85% version; some don't. Read the policy's general conditions to confirm, or ask your intermediary to point out the specific wording.

If my policy has a reinstatement value condition, does average still apply?

Yes. Reinstatement value changes the benchmark against which adequacy is measured, it becomes replacement cost rather than depreciated value. If your sum insured is below that replacement cost, the average clause still reduces your claim.

Does the average clause apply to total losses?

In standard fire policy practice, the average clause's practical effect is most visible on partial losses. On total losses, the sum insured itself caps the payout, so the clause often doesn't reduce the payout further, but the sum-insured cap means you still don't recover the full reinstatement cost if you were underinsured.

What's the difference between average clause and coinsurance?

In Malaysian insurance usage, "average clause" and "coinsurance" are sometimes used interchangeably to refer to the same mechanism, the adequacy-based reduction of claims. In some international markets, "coinsurance" has a different technical meaning. Check the policy wording for the exact language.

Can I negotiate the average clause out of my policy?

On standard tariff fire policies, no, the clause is part of the standard wording. On non-tariff products and larger industrial risks, specific amendments to the clause (like the 85% threshold) can sometimes be negotiated. This is where a specialist intermediary adds value.

Do I get my premium refunded if I was overinsured?

Overinsurance doesn't trigger a claim reduction, the insurer simply pays the actual loss amount, capped at the sum insured. But you'll have paid premium on a sum insured higher than necessary. The refund only happens if you actively reduce the sum insured during the policy year.

How often should I review my sum insured?

Annually at renewal, at minimum. Also whenever there's a material change: new machinery, expansion, significant inventory increase, or completion of fit-out works. A value drift of even 10% over two years can turn a clean policy into an underinsured one.

Foundation Conclusion

The average clause is the quiet mechanism that converts a reasonable-looking fire policy into a materially reduced payout when a claim happens. The fix is not complicated, set the sum insured at reinstatement value, review annually, and watch for value creep, but the consequence of not doing it is expensive in a way that only becomes visible after the loss.

Foundation reviews fire insurance and IAR policies for Malaysian factory owners, commercial landlords, and industrial operators. The sum insured adequacy review is usually the single most valuable 30 minutes we can spend on a policy, before a claim rather than after.
