Which endorsement grants broad Additional Insured status to multiple parties?

• A. Blanket Additional Insured endorsement
• B. Subrogation waiver endorsement
• C. Pollution endorsement
• D. Employment Practices endorsement

Answer: (A)

A blanket Additional Insured endorsement is designed to extend AI protection to a broad group of parties automatically. It covers multiple entities that the insured is contractually required to name, without needing a separate endorsement for each one. This is especially useful on complex projects with many stakeholders—owners, contractors, designers, and other contract parties—because the endorsement can apply to all designated parties under a single provision and typically covers both ongoing operations (and sometimes completed operations) as specified. It can also be arranged to be primary and non-contributory if requested.

The other endorsements don’t provide this wide-spread AI coverage. A subrogation waiver stops the insurer from pursuing recovery after a loss, rather than adding additional insureds. A pollution endorsement addresses pollution liability, not AI status. An Employment Practices endorsement deals with employment-related liability. So the blanket Additional Insured endorsement best grants broad AI status to multiple parties.
