7.5 General Premium Computation and Insurance Documents

Build the Premium from Stated Inputs

The underwriting rate converts exposure into a risk premium. The gross premium must also fund expenses, distribution, contingencies and profit. A rate written as a percentage of the sum insured differs from a rate per RM1,000 or a fixed amount per vehicle. Read the units before multiplying. Exam calculations normally provide enough inputs; do not invent a rate from the customer's age or property description.

Tariff examples explain a rating method. They are not promises that every insurer quotes identical premiums today. Malaysia's phased motor and fire liberalisation allows risk-based pricing within the applicable framework. For comprehensive and third-party fire-and-theft motor cover, quotation differences can reflect risk information and underwriting models. Distinguish the historical tariff exercise from the customer's current insurer quotation.

A Worked Fire Premium

Assume a teaching policy insures a building for RM500,000, machinery for RM200,000 and stock for RM100,000. All three items use a stated basic rate of 0.20%. The total sum insured is RM800,000, so basic premium is RM800,000 × 0.002 = RM1,600. Treating 0.20% as 0.20 would incorrectly produce RM160,000.

Assume the question specifies a flood extension at 0.05% on all three items and an electrical extension at 0.04% on machinery alone. Flood premium is RM800,000 × 0.0005 = RM400. Electrical premium is RM200,000 × 0.0004 = RM80. The gross premium before any separately stated taxes or fees is RM2,080. Do not apply the machinery-only rate to the entire building and stock total.

These are hypothetical rates, not a current insurer tariff. If the question supplies an approved discount or a tax, follow its stated base and order. Do not silently use a dated textbook tax rate. The objective is correct arithmetic with the applicable information, rather than memorising an obsolete quotation.

A Worked Motor Premium

Assume an insurer quotes RM1,200 of basic motor premium, with a 30% No Claim Discount on that basic premium only. The discount is RM360 and the discounted basic premium is RM840. The customer also chooses an extension costing RM150 that is expressly excluded from NCD. The premium before other stated charges is RM990. Applying 30% to the combined RM1,350 would incorrectly discount the extension too.

Risk-based rating may consider vehicle, use, driver and claims factors, but the agent must enter accurate information and use the insurer's approved quotation. An optional excess can affect price only where the insurer offers that choice. The cheapest quote cannot be assessed without checking cover, sum insured, excess, endorsements and service. A lower premium for cover excluding flood is not equivalent to a higher quote that includes it.

Documents in the Insurance Sequence

The proposal form records risk information and the requested insurance. It supports selection and pricing, but submitting it is not necessarily acceptance. A cover note can provide temporary insurance within its stated authority, period and terms. A motor e-cover note supports electronic administration; electronic format does not extend the cover beyond what was granted.

A certificate of insurance supplies evidence for its stated purpose, especially statutory motor insurance. It should be consistent with the policy and actual vehicle use. The policy contains the agreement, schedule, conditions and exclusions, with endorsements recording agreed amendments. A certificate is not a convenient replacement for reading the policy when resolving a coverage dispute.

A renewal notice prompts the customer to review expiring cover and provide updated information. It can identify the proposed renewal premium and values, but the customer should still establish acceptance, payment requirements and renewal commencement. A renewal certificate confirms renewed cover on the stated terms. Changes in benefits, exclusions or use must be communicated and recorded; do not simply assume every prior term continues unchanged.

Agent Checks and Common Traps

Suppose a shop adds expensive equipment shortly before renewal. The old machinery value may no longer be adequate, even if the insurer has sent a notice based on last year's data. Review values and exposures and submit the requested change. A renewal reminder does not update the sum insured by itself, and paying the old premium does not necessarily insure an undisclosed new operation.

Check names, addresses, dates, vehicle or property details, limits and endorsements across the documents. Resolve discrepancies through the insurer and retain the corrected version. Never alter a certificate privately to match a customer's preferred description. If a claim occurs during temporary cover, identify the actual cover note terms and time of loss, rather than looking only at the later policy issue date.

For premium questions, write the rate unit, calculate each component, apply only the authorised discount base, then add the separately stated charges. For document questions, identify the purpose and legal effect of each document. These two habits prevent arithmetic errors and the equally costly assumption that a quotation, receipt or renewal invitation proves unconditional insurance.
