The standard Amendment of Insured Contract Definition commercial general liability (CGL) endorsement (CG 24 26) alters the policy's definition of "insured contract," which determines the scope of coverage for contractually assumed liabilities, to require that the injury or damage for which coverage is sought was caused "in whole or in part" by the named insured or those acting for it.
Introduced in 2004, the intent of the endorsement is to cause the policy's contractual liability coverage to match more closely the protection provided under the 2004 additional insured endorsements.
