Definition:All-risks coverage
📋 All-risks coverage is a form of property insurance that covers any cause of loss unless the policy specifically excludes it — the opposite of a named perils approach, which only pays for losses from causes explicitly listed. In commercial and personal lines alike, all-risks (sometimes called "open perils" or "special form") coverage is considered the broadest protection available, and it shifts the burden of proof: the insured need only demonstrate that a loss occurred, while the insurer must show that an exclusion applies if it intends to deny the claim.
⚙️ Under an all-risks policy, the underwriter prices the coverage by evaluating the full spectrum of exposures a property faces, then relies on carefully drafted exclusions — for perils like flood, earthquake, war, nuclear hazard, wear and tear, and intentional acts — to carve out risks the insurer is unwilling or unable to cover at the quoted premium. Standard forms such as the ISO Commercial Property CP 10 30 (Causes of Loss — Special Form) embody this approach for commercial risks. Policyholders can often buy back some excluded perils through endorsements or standalone policies, layering coverages to approach truly comprehensive protection.
🔍 The practical advantage of all-risks coverage lies in its treatment of unforeseen or unusual loss events. Because coverage applies by default, the insured is protected even against perils that neither party anticipated at inception — a crucial benefit in a world where emerging risks like cyber incidents or supply-chain disruptions can damage physical property in novel ways. Disputes over all-risks policies tend to center on exclusion interpretation, making clear policy language and thorough claims investigation essential. For brokers advising clients, recommending all-risks coverage over named perils is often a straightforward value proposition, especially for high-value commercial properties where a gap in coverage could be financially devastating.
