Common Policy Conditions — the part of the insurance policy typically relating to cancellation, changes in coverage, audits, inspections, premiums, and assignment of the policy. The commercial lines policy forms portfolio promulgated by Insurance Services Office, Inc. (ISO), takes a modular approach to structuring policies. A commercial lines policy is made up of a declarations page, the common policy conditions, one or more coverage forms, and endorsements that modify the coverage forms. The common policy conditions form (IL 00 17) is used with the commercial property, general liability, and crime forms to specify the conditions applicable to the policy.
