Business Insurance
Primary and Noncontributory
A primary and noncontributory requirement — common in construction and service contracts — ensures that one party's insurance pays before and independently of the other party's coverage.

Definition
A primary and noncontributory (P&NC) policy condition specifies that the insured's policy will respond first as primary coverage and will not seek contribution from any other available insurance the additional insured may have. Without this endorsement, when two policies cover the same loss they typically share the payment proportionally, which can create billing disputes and delays. A general contractor requiring its subcontractors to carry P&NC coverage ensures that if the sub's work causes a claim, the sub's insurance pays the full bill before the GC's insurer is ever involved. P&NC requirements are most common in commercial construction, property management, and government contracting, and failure to include the endorsement on a COI can result in subcontractors being removed from job sites. The endorsement is usually low-cost but requires underwriter approval, and some insurers restrict P&NC for certain high-limits additional insured requirements. Businesses should confirm that their GL policy includes a blanket P&NC endorsement to avoid scrambling to add it for each new contract.
