Sum Insured Guide: Reinstatement vs Market Value for Malaysian Factories

Your factory is insured for RM5 million. A fire destroys a section worth RM2 million. You file a claim expecting full payment. The insurer's adjuster arrives, calculates your actual reinstatement value at RM10 million, and applies the average clause. Your payout: RM1 million.

This guide explains how to set the correct sum insured for your factory, the difference between reinstatement and market value, and how to avoid the average clause that cuts your claim in half.

This guide covers:

• Reinstatement value vs market value vs book value
• How the average clause (condition of average) works
• Correct valuation methods for buildings, machinery, and stock
• The 85% threshold for IAR policies
• When you need a professional valuation

Three Ways to Value Your Factory Assets

Insurance companies in Malaysia use three different valuation bases for property insurance. Choosing the wrong one can leave you massively under-insured or paying premiums for coverage you can't use.

Valuation Basis	Definition	When to Use
Reinstatement Value (New-for-Old)	Cost to rebuild, repair, or replace with new equivalent. No deduction for depreciation.	Buildings, plant, and machinery under IAR or Fire policies
Market / Indemnity Value (Old-for-Old)	Cost to repair or replace, minus depreciation for wear and tear. You get the value of the asset in its pre-loss condition.	Older assets nearing end-of-life; stock and inventory
Book Value (Accounting)	Original purchase price minus accumulated depreciation per accounting records.	Never use for insurance. Book value is an accounting concept, not a measure of replacement cost.

Here's the problem: most factory owners use book value or market value because that's what appears in their financial statements. But after a total loss, you don't need the depreciated value of your old building. You need enough money to build a new one.

Reinstatement Value: What It Actually Means

Reinstatement value is the cost to rebuild your factory to the same size and specification as new. For a 20-year-old factory, this figure is almost always higher than the market value of the existing building, because construction costs have increased while the building has depreciated.

A correct reinstatement valuation for a building should include all of the following components.

Component	Include in Sum Insured?	Notes
Main building structure	Yes	Full rebuild cost as new
Demolition and debris removal	Yes	Cost to clear damaged structure before rebuilding
Architect, surveyor, QS fees	Yes	Professional fees for redesign and project management
M&E consultant fees	Yes	Mechanical and electrical systems design
Landlord's fixtures and fittings	Yes	Items permanently attached to the building
Land value	No	Land can't be destroyed by fire; it's not an insurable interest for property damage
Tenant's improvements	Separate item	Insured by tenant, not landlord

Why Market Value Is Wrong for Factory Insurance

Market value of a property includes land value and reflects depreciation. Fire insurance only covers the building structure, not the land. And reinstatement-basis policies pay the cost of rebuilding as new, not the depreciated value.

This creates a common situation in Malaysia where the reinstatement value is significantly higher than the market value.

Component	Illustrative Figures
Market value of property	RM5,000,000
Less: Land value (not insurable)	(RM1,500,000)
Depreciated building value	RM3,500,000
Reinstatement cost (rebuild as new)	RM7,000,000
Gap if insured at market value	RM3,500,000 under-insured

In this example, the factory owner who insures at market value (RM5 million) is actually RM2 million under-insured. The owner who insures at depreciated building value (RM3.5 million) is RM3.5 million under-insured. Both will face the average clause at claims time.

The Average Clause: How Under-Insurance Reduces Your Claim

The Condition of Average is a standard clause in Malaysian fire and IAR policies. If your sum insured is less than the actual value at risk, the insurer pays only a proportional share of any loss. You effectively become your own co-insurer for the uninsured portion.

The formula is straightforward:

Average Clause Formula
Claim Payout = (Sum Insured / Actual Value at Risk) x Loss Amount

Worked Example

Item	Amount
Actual reinstatement value of factory building	RM10,000,000
Sum insured on policy	RM5,000,000 (50% of actual)
Fire damage (partial loss)	RM2,000,000
Claim payout after average clause	RM1,000,000 (50% of RM2M)
Factory owner bears	RM1,000,000 out of pocket

The insured thought they had enough coverage for a RM2 million loss. But because they only insured 50% of the true value, they only received 50% of the claim. The average clause applies to every partial loss, not just total losses.

The 85% Threshold for IAR Policies

Industrial All Risks (IAR) policies in Malaysia have a built-in tolerance for minor under-insurance. If your sum insured is at least 85% of the actual value at risk, the average clause does not apply. You receive the full claim amount up to your sum insured.

But if your sum insured falls below 85%, the full average clause kicks in proportionally.

Scenario	Actual Value	Sum Insured	% Insured	Average Applied?
A	RM10M	RM9M	90%	No (above 85%)
B	RM10M	RM8.5M	85%	No (at 85%)
C	RM10M	RM7M	70%	Yes (below 85%)
D	RM10M	RM5M	50%	Yes (below 85%)

This 85% threshold is specific to IAR policies. Standard Fire Insurance policies typically apply the average clause from the first ringgit of under-insurance with no tolerance buffer.

How to Value Each Asset Type

Different asset types require different valuation approaches. Getting this wrong is the single most common cause of under-insurance in Malaysian factories.

Asset Type	Correct Valuation Basis	Common Mistake
Buildings and structures	Reinstatement (cost to rebuild as new, excluding land)	Using market value which includes land and deducts depreciation
Plant and machinery	Replacement value (cost of new equivalent, including installation and commissioning)	Using accounting book value (net of depreciation)
Electronic equipment	Replacement value (new equivalent with similar specs)	Using original purchase price (technology may be cheaper or more expensive now)
Stock and raw materials	Cost price or current market value (whichever applies)	Using annual average instead of peak inventory level
Finished goods	Cost of production (materials + labour + overheads)	Using selling price (profit is not insurable under property policies)
Moulds, dies, patterns	Replacement or reproduction cost	Excluding them entirely from the sum insured

Machinery Valuation: Purchase Price vs Replacement Value

For Machinery Breakdown and EEI policies, the sum insured should be the current replacement value, not the original purchase price. Machinery bought 10 years ago may cost significantly more to replace today due to inflation, currency fluctuations, and changes in technology.

The replacement value for machinery should include everything needed to get the machine operational again.

Include in Machinery Sum Insured	Notes
Purchase price of new equivalent machine	Current price, not historical
Freight and import duties	CIF value for imported machinery
Installation, erection, and commissioning	Labour and specialist costs to install
Foundation and civil works	If machinery requires specific foundations
Customs clearance and local transport	From port to factory site

Stock Valuation: Average vs Peak

Stock is one of the most commonly under-insured items. Many factory owners insure stock at the annual average level, but a fire doesn't always happen when stock is at average. If it happens during peak season or after a large shipment arrives, the actual stock value could be double the average.

Approach	Sum Insured Basis	Risk
Annual average stock	Average monthly stock value over 12 months	Under-insured during peak months; average clause applies
Peak stock value	Maximum stock value at any point during the year	Higher premium but no under-insurance risk
Declaration basis	Monthly declarations; premium adjusted at year-end	Best approach for fluctuating stock; requires admin discipline

The declaration basis is the most accurate method for factories with seasonal fluctuations. You pay a deposit premium upfront based on estimated maximum, then declare actual stock values monthly. At renewal, the premium is adjusted based on the average of your declarations.

Common Causes of Under-Insurance in Malaysian Factories

Under-insurance rarely happens because factory owners deliberately choose to insure less. It happens because valuations become outdated, assets get added without updating the policy, or the wrong valuation method was used from the start.

Cause	Why It Happens	Fix
Using book value instead of reinstatement	Accounting and insurance serve different purposes	Get a professional reinstatement valuation
Not updating for construction cost inflation	Building costs rise while sum insured stays flat year after year	Review building sums insured annually; revalue every 3-5 years
Excluding professional fees	Architect/QS/M&E fees can add 10-15% to rebuild cost	Include a professional fees provision in the sum insured
New machinery not added to policy	Capex approved and installed but insurer not notified	Notify insurer within policy's automatic addition period
Currency depreciation on imported machinery	Machine bought in USD/EUR; RM sum insured hasn't kept pace	Revalue imported machinery at current exchange rates
Stock insured at annual average	Loss occurs during peak season when stock exceeds average	Insure at peak value or use declaration basis

When You Need a Professional Valuation

A professional reinstatement valuation by a registered valuer provides a defensible sum insured figure that will withstand scrutiny during a claim. It's not legally required for all factory insurance, but there are situations where it's strongly recommended.

Situation	Professional Valuation Needed?
Factory building is more than 10 years old	Strongly recommended (construction costs have likely increased)
Strata property (under Strata Management Act 2013)	Legally required at least every 5 years (Section 94)
Major renovations or extensions completed	Yes, to capture the increased rebuild cost
Specialist or purpose-built factory	Yes (standard cost-per-sqft estimates may be inaccurate)
You've never had a professional valuation done	Yes, to establish a baseline

Under the Strata Management Act 2013 (Section 94), buildings under strata title must be insured for at least the reinstatement value as indicated by the latest professional valuation. A reinstatement valuation by a registered valuer is required at least once every five years.

FAQ

What is the difference between reinstatement value and market value for insurance?

Reinstatement value is the cost to rebuild or replace as new with no deduction for depreciation. Market value includes land and reflects depreciation. For factory insurance, you should use reinstatement value because you need enough to rebuild, not the price someone would pay for the old building.

What happens if my factory is under-insured?

The average clause applies. Your claim payout is reduced proportionally. If you're insured for 50% of the actual value, you'll only receive 50% of any claim, even for partial losses. This applies to both Fire and IAR policies.

Does the average clause apply to IAR policies?

Yes, but IAR policies have an 85% tolerance. If your sum insured is at least 85% of the actual value at risk, the average clause doesn't apply. Below 85%, the full average formula kicks in. Standard Fire Insurance has no such tolerance.

Should I include land value in my sum insured?

No. Land cannot be destroyed by fire, flood, or explosion. It's not an insurable interest for property damage policies. Including land value inflates your premium without adding useful coverage. Exclude it completely and focus on the building reinstatement cost.

How often should I revalue my factory?

A full professional reinstatement valuation every 3 to 5 years is good practice. Between valuations, adjust the sum insured annually to account for construction cost inflation. For strata properties, the Strata Management Act 2013 requires a valuation at least every 5 years.

Can I use my company's fixed asset register for the sum insured?

No. The fixed asset register shows accounting book value (purchase price minus depreciation), which is almost always lower than the actual cost to replace or rebuild. Using book value for insurance will result in under-insurance and reduced claims payouts.

What is the correct sum insured for imported machinery?

The current replacement value including: the price of a new equivalent machine, freight, insurance in transit, import duties, customs clearance, local transport, installation, and commissioning. Use current exchange rates for the RM equivalent, not the rate when you originally purchased it.

How does the declaration basis work for stock?

You pay a deposit premium based on estimated maximum stock. Each month, you declare the actual stock value to the insurer. At policy renewal, the premium is adjusted based on the average of your monthly declarations. This approach ensures you're covered at peak levels without overpaying based on annual maximums.

Foundation Conclusion

Under-insurance is one of the most common and most expensive mistakes in Malaysian factory insurance. The gap between what you think you're covered for and what the insurer will actually pay only becomes visible at claims time, when it's too late to fix.

Getting the sum insured right at the start, and reviewing it every year, is the most cost-effective thing you can do for your factory's financial protection.
