The Insurance Services Office, Inc. (ISO) issued several new and revised endorsements for use with Commercial General Liability (CGL) coverage forms, which became effective December 1, 2019, in most jurisdictions. The new ISO endorsements include several notable changes that Policyholders should be aware of, including revisions to existing Additional Insured (AI), Primary and Noncontributory, and Waiver of Subrogation endorsements, as well as a number of new AI and other endorsement forms. A summary of the more significant elements of new ISO endorsements is provided below.


  • New AI Endorsements - Automatic Status for Completed Operations

For Contractors, Owners and other construction industry stakeholders, there are two new AI endorsements of note, CG 20 39 12 19 – Additional Insured – Owners, Lessee or Contractors – Automatic Status when Required in Written Construction Agreement with You (Completed Operations) and CG 20 40 12 19 – Additional Insured – Owners Lessees or Contractors – Automatic Status for Other Parties when Required in Written Construction Agreement (Completed Operations). AI coverage for Completed Operations is generally provided under form CG 20 37, which requires each additional insured to be listed in the endorsement schedule. The new ISO endorsements automatically extend AI status for Completed Operations without having to specifically identify each additional insured, thereby mirroring current AI endorsements that confer automatic AI status for Ongoing Operations (e.g. CG 20 33 and CG 20 38). Thus, the CG 20 39 and CG 20 40, correspond with CG 20 33 (ongoing operations), and CG 20 38 (ongoing operations), respectively, to extend AI coverage for Completed Operations.
