additional insured (AI)

A named insured's impetus for providing additional insured status to others may be a desire to protect the other party because of a close relationship with that party (e.g., wanting to protect church members performing services for the insured church) or to comply with a contractual agreement requiring the named insured to do so (e.g., project owners, customers, or owners of property leased by the named insured). In liability insurance, additional insured status is commonly used in conjunction with an indemnity agreement between the named insured (the indemnitor) and the party requesting additional insured status (the indemnitee). Having the rights of an insured under its indemnitor's commercial general liability (CGL) policy is viewed by most indemnitees as a way of backing up the promise of indemnification. If the indemnity agreement proves unenforceable for some reason, the indemnitee may still be able to obtain coverage for its liability by making a claim directly as an additional insured under the indemnitor's CGL policy. In property insurance, additional insured status is most often used in conjunction with a premises lease agreement between the named insured as the lessee and the owner of the leased building, in which the insured tenant is required to purchase insurance on the leased building and name the building owner as an additional insured on the insurance policy with respect to the leased building.
