BIA Non-Life Insurance Diploma common mistakes
BIA Non-Life Insurance Diploma · Understand the traps and how to avoid them.
When asked whether a duty of utmost good faith or a duty of fair presentation was breached, candidates write a general statement that the insured 'should have told the insurer everything' instead of identifying the specific material facts that were not disclosed and whether the insured knew, or ought to have known, them.
Candidates learn the principle as a slogan and never practise applying the disclosure test to a concrete fact pattern, so they cannot separate material facts from immaterial ones or distinguish actual from constructive knowledge.
What to do instead
Before writing, list each undisclosed fact in the scenario, then for each state whether it is material to the particular underwriter, whether the insured actually knew it, and whether a reasonable insured in their position ought to have known it. Answer in that three-step structure so the marker can see the test being applied rather than asserted.
Candidates describe indemnity, insurable interest, subrogation and contribution as separate definitions and never explain how they interact in a single claim, for example failing to explain that subrogation recovery is capped by the indemnity principle and that contribution requires common liability for the same loss.
Revision is organised topic by topic, so each principle is memorised in isolation and the connective reasoning between them is never rehearsed.
What to do instead
For each of these principles, prepare a worked example with numbers showing the interaction, such as a double-insured property loss where contribution shares the loss and subrogation then recovers only the unindemnified balance. Practise writing the linked explanation in under 150 words so it becomes the default answer shape.
In policy wording questions, candidates quote the exclusion or condition from memory in loose paraphrase and then apply it without first establishing whether the insured event falls within the insuring clause at all.
Exclusions feel like the interesting part of the question, so candidates jump straight to them and skip the prior step of construing the grant of cover, which reverses the correct order of analysis.
What to do instead
Adopt a fixed sequence for every wording question: identify the insuring clause and its scope, test the facts against it, then apply exclusions, then conditions, then consider the effect of any statutory override. Write the headings out in that order before drafting prose.
On business interruption questions, candidates calculate the gross profit loss without adjusting for the indemnity period, the increase in cost of working, or the saved uninsured expenses, and they confuse rate of gross profit with gross profit itself.
The arithmetic of the gross profit formula is taught as a formula to memorise, and candidates rarely practise it against a scenario with a partial indemnity period and a cost of working that reduces the loss.
What to do instead
Work through at least five numerical scenarios end to end, each time writing out turnover, rate of gross profit, the indemnity period fraction, the increase in cost of working, and the deduction for saved expenses as separate labelled lines. Check that the final figure never exceeds what the business would have earned had the loss not occurred.
When a liability claim arises, candidates state that the insurer must pay the claimant and stop there, without addressing the claims-made versus occurrence trigger, the limit of indemnity inclusive of defence costs, and any aggregation wording that could cap multiple claims at one limit.
Candidates conflate the insured's legal liability with the insurer's payment obligation and overlook that the trigger, the limit and aggregation each independently determine whether and how much is payable.
What to do instead
For every liability scenario, answer three questions in writing before concluding: which policy year is triggered, what is the limit and is it inclusive or in addition to defence costs, and do the claims aggregate to a single limit under the wording. Only then state the amount payable.
In motor questions, candidates apply the policy terms to a claim involving an uninsured or untraced driver and ignore the statutory framework that determines whether the insurer or a compensation body must respond, and on what basis the insurer may then recover.
Motor cover is treated as straightforward and revision focuses on the policy schedule, so the statutory overlay and the recovery rights it creates are under-rehearsed.
What to do instead
Build a one-page decision tree for motor claims covering insured driver, uninsured driver, untraced driver and stolen vehicle, with the statutory route and the insurer's recovery right noted at each branch. Rehearse it against three short scenarios until the sequence is automatic.
On reinsurance questions, candidates describe proportional and non-proportional reinsurance as definitions and then fail to explain how a single loss or a series of losses is allocated between the layers, or how the reinsurance recovery interacts with the original policy limit and deductible.
The mechanics of layering and allocation require numerical reasoning that candidates avoid in favour of reciting definitions, which score few marks.
What to do instead
Practise allocation with worked numbers: take a loss, apply the original deductible, apply the retention, then allocate across quota share, surplus and excess of loss layers in order. Write the allocation as a table with a running total so arithmetic errors and double counting are visible.
In claims and fraud questions, candidates assert that the claim should be declined for fraud without distinguishing fraudulent exaggeration of a genuine claim from a wholly fabricated claim, and without considering the effect of a fraudulent claims clause on the genuine part of the loss.
Fraud is treated as a single category, so candidates apply the harshest outcome to every scenario and miss the contractual and case-law distinction that determines whether the whole claim or only the exaggerated element is forfeited.
What to do instead
Classify the scenario first as fabrication, exaggeration, or non-disclosure, then apply the specific fraudulent claims condition in the wording and state its effect on the genuine element. Write one sentence justifying the classification before stating the outcome.
On reserving and solvency questions, candidates calculate a reserve as a single figure without separating incurred but not reported claims, outstanding reported claims and unexpired risk, and without explaining how the reserve feeds into the capital requirement.
Reserving is perceived as an actuarial topic outside the candidate's comfort zone, so answers stay qualitative and never demonstrate the link between reserve adequacy, technical provisions and solvency capital.
What to do instead
Learn the components of technical provisions as a labelled list and practise a short numerical example in which a change in the IBNR estimate flows through to the capital position. State the direction of the effect explicitly, for example that an adverse development increases required capital and reduces free surplus.
On ethics questions, candidates identify the conflict of interest and then recommend disclosure to the client as the complete remedy, without considering whether the firm should decline the instruction, obtain informed consent, or escalate internally, and without identifying who is owed the duty.
Candidates reach for the most familiar control and stop, rather than working through the hierarchy of responses and identifying the parties to whom the duty is owed.
What to do instead
For each ethics scenario, name the parties owed a duty, state the specific conflict, then rank the available responses from avoidance through controls to disclosure, and justify why the chosen response is proportionate. Finish by stating what record should be made and who should approve it.
