Which statement correctly describes the characteristics of ideally insurable loss exposures?

• A. Ideally, loss exposures should be spread across a large number of similar exposure units within the same period.
• B. They should concentrate losses in a few large exposure units to maximize diversification.
• C. They should be unpredictable and highly variable to ensure premium income.
• D. They should be insured with a single insurer to simplify claims.

Answer: (A)

Pooling risk by spreading losses across a large number of similar exposure units makes losses more predictable and manageable for an insurer. When you have many similar units, the random variation in individual losses tends to offset each other, so the total loss experience converges to an expected value. This use of the law of large numbers allows the insurer to estimate average loss, set appropriate premiums, and cover expenses and a reasonable profit. Keeping the exposures within the same period helps align claims experience with underwriting and pricing cycles, making the premium a fair reflection of anticipated losses for that period. For an exposure to be ideally insurable, losses should be random and measurable, but the central feature enabling insurability is the ability to pool risk across a broad, homogeneous base. The other ideas don’t fit as well because concentrating losses in a few large units undermines diversification; unpredictable and highly variable losses make pricing and reserve setting unreliable; and insuring with a single insurer isn’t necessary and can create concentration risk that defeats the purpose of pooling.
