CG 20 01 Primary and Noncontributory – Other Insurance Condition

An Insurance Services Office (ISO) standard form. It makes your coverage primary and noncontributory for an additional insured when the additional insured is a Named Insured on its own policy and you agreed in a written contract that your insurance would be primary and noncontributory.
