Why it matters for your company
Most of what matters in a policy lives in its endorsements. Additional insured status, a waiver of subrogation, an AI exclusion, a sublimit on one kind of claim: each arrives as an endorsement listed on the declarations page, and each changes what the base form says.
Renewals are where endorsements move. A policy can renew at the same limit and similar price with a new exclusion attached, and nothing in the quote summary tells you. Reading the endorsement schedule against last year's is the one habit that catches it before a claim does.
Related terms
- ExclusionA clause that removes a type of loss, activity or property from what a policy responds to. Exclusions sit in the base form and in endorsements, and at claim time they decide the outcome more often than the coverage grant does.
- Additional insuredA person or company added to your policy by endorsement so they can claim under it too, usually a landlord or customer whose contract asks for it. They get a right to defense and payment for claims arising from your work, within the limits of the endorsement.
- Generative AI exclusionAn endorsement that removes coverage for claims arising out of generative artificial intelligence. Standard-form versions for general liability, including one for products and completed operations, took effect in January 2026.
- SublimitA smaller cap inside a policy's main limit that applies to one kind of loss. A $3M cyber policy with a $250,000 sublimit for social engineering pays no more than $250,000 for that claim.
