UNDERWRITING & DISCLOSURE
Material fact definition
A material fact is information that would influence an insurer’s decision to offer cover, set terms or calculate premium.
In practice, this means a material fact is any fact that would influence the judgement of a prudent insurer in determining whether to underwrite a risk and/or in establishing the terms and premium rate on which to underwrite it. Those taking out an insurance policy are obliged to disclose material facts before an insurance policy begins, at every renewal and throughout the duration of the policy whenever circumstances change. This term gives insurers, brokers, reinsurers and risk managers a common way to discuss the concept when reviewing policies, claims, regulation or market data.
This term is especially useful in insurance market analysis, policy wording and risk transfer decisions. It helps determine when cover applies and what obligations exist under the insurance contract. It also helps users compare how insurance is structured, regulated, priced or claimed across different markets.
Material fact is closely related to duty of disclosure, utmost good faith, underwriting and misrepresentation. Linking these concepts together helps build a clearer glossary structure and gives readers a stronger understanding of how individual insurance terms connect within wider international insurance practice.
