Coverage applying to all liability assumed by the insured in contracts, whether reported to the insurer or not. Note that the term "blanket contractual liability insurance" does not address the extent of the transferred liability the policy covers, only that it is not necessary to report contracts to the insurer for listing in the policy. It is possible to have blanket broad form contractual liability insurance or blanket limited form contractual liability insurance. Contractual liability coverage was added to 1973 and earlier edition comprehensive general liability (CGL) policies by endorsement. Blanket broad form contractual liability coverage is incorporated into the basic provisions of the 1986 and subsequent commercial general liability (CGL) forms.
