Principles of Insurance and Risk Management: Pooling, Insurable Risk and Handling Techniques
This domain tests whether you can classify risk, apply the criteria that make a risk insurable, and choose a risk-handling technique with reasons. Questions often present a loss exposure and ask which treatment is appropriate.
What makes a risk insurable
Insurance handles pure risk (loss or no loss), not speculative risk (loss or gain). Courts and texts require: many homogeneous exposure units, accidental and fortuitous loss, a definite and measurable loss, a loss that is not catastrophic to the pool, calculable probability, a lawful subject matter, insurable interest, and a premium the buyer can afford. Correlation destroys pooling, which is why catastrophe cover is layered and reinsured.
Handling techniques and mechanics
Avoidance, loss prevention and control, retention (deductibles, self-insured retentions, captives), transfer (insurance, contractual transfer) and diversification. The management cycle is identify, measure frequency and severity, select, implement, monitor. Insurance itself rests on the law of large numbers, which stabilises expected loss as exposures grow; adverse selection and moral hazard (careless or dishonest conduct) or morale hazard (indifference after transfer) push actual losses above the assumption.
Worked example
A distributor runs 400 trucks. Historical frequency is 2% total loss per year with an average value of P2 million: expected annual loss is 400 x 0.02 x P2M = P16M. Adding 30% for expenses, profit and contingency gives a technical premium of about P20.8M. The client instead keeps a P50,000 deductible per claim, retaining only predictable attritional damage while transferring the severity spike to the insurer - cheaper than full first-dollar cover and still funded for expected losses.
Traps
- Treating price or currency speculation as insurable.
- Confusing moral hazard with morale hazard.
- Forgetting that insurance finances loss; it does not prevent it.
- Ignoring correlation: a single typhoon can hit every insured in the pool at once.
