The correct answer is C. Applies to losses below a specific amount . A self-insured retention, or SIR, is an amount of loss that the insured must retain and pay before the insurer’s obligation applies. It is commonly used in liability programs, especially for larger or more sophisticated insureds that are willing to retain predictable or lower-level losses. The key difference from many deductibles is that an SIR often means the insured is responsible for handling and funding losses within the retained layer, while the insurer responds only after the SIR is exhausted, depending on wording. A deductible usually forms part of the insured loss under the policy, with the insurer often adjusting the claim and recovering or applying the deductible amount. Option A is not precise because SIR is risk retention, not insurance. Option B is not the best distinguishing feature and depends on wording and limit structure. Option D is wrong because SIRs can strongly encourage loss prevention by making the insured financially responsible for smaller losses. The best answer is that the SIR applies to the layer of losses below a stated threshold.
