Definition:Claims-made
đ Claims-made is a policy form structure under which coverage is triggered when a claim is first reported to the insurer during the active policy periodâregardless of when the underlying incident actually occurred. This stands in contrast to an occurrence-based policy, where the date of the loss event itself determines whether coverage applies. Claims-made policies are the dominant form in professional liability, directors and officers (D&O), and cyber insurance, where harmful events can remain hidden for months or years before a claim surfaces.
âď¸ Because the reporting date drives coverage, claims-made policies introduce several mechanisms that shape the policyholder's protection window. A retroactive date sets the earliest point from which covered acts are eligible; any incident predating that boundary falls outside the policy's scope even if reported during the current term. Meanwhile, an extended reporting periodâoften called a "tail"âcan be purchased to allow the insured to report claims after the policy expires, which is critical when switching carriers or ceasing operations. Underwriters favor the claims-made structure partly because it gives them tighter control over reserving: the universe of potential claims is bounded by the policy's reporting window rather than left open-ended.
đ For insureds, understanding the claims-made trigger is vital because a gap in coverageâeven a single day without a policy in forceâcan leave an entire period of professional activity unprotected. Brokers advising clients in E&O or medical malpractice must ensure that retroactive dates are preserved when policies are renewed or moved to a new carrier. From the insurer's perspective, the claims-made form offers more predictable loss development patterns and reduces the long-tail uncertainty that plagues occurrence-based casualty lines.
