The basic extended reporting period (BERP) is the extended reporting periods (ERPs) the 1986 Insurance Services Office, Inc. (ISO), claims-made commercial general liability (CGL) policy automatically provides to the insured when a claims-made policy is canceled, not renewed, renewed with a laser exclusion, or renewed with an advanced retroactive date.
They are 60 days and 5 years. BERPs are also included in some claims-made professional liability policies. In professional liability policies, BERPs extend the reporting period for 30 to 60 days at no additional charge when the insurer cancels or nonrenews the policy. In a few instances, they are offered when the insured cancels or nonrenews the policy.
