Which statement describes a unique characteristic of how insurance pricing works, where rates are set before actual costs are known?

• A. Insurer set rates before the actual costs are known
• B. Rates are based on actual costs after losses occur
• C. Rates are identical across all lines
• D. The regulatory process waits until losses are observed

Answer: (A)

Forward-looking rate-making is at the heart of insurance pricing: premiums are set before actual losses are known. Actuaries use expected future costs, based on exposure units (like vehicles insured or policy years), historical loss experience, and amounts for expenses and profit, to estimate what claims will cost over the policy period. Because the insurer cannot (and does not) wait for losses to occur to set a price, the premium reflects an educated forecast of future costs, not the exact costs that will eventually be realized. The other ideas describe retrospective pricing, uniform pricing across risk, or regulatory delay, none of which capture how insurance pricing is actually determined.
