Definition:Master policy

📄 Master policy is a single, overarching insurance contract that provides coverage for a group of individuals or multiple locations under one agreement, rather than issuing separate policies to each insured party. In insurance, master policies are most commonly found in group insurance programs — such as employer-sponsored group life, group health, and group disability — as well as in blanket property arrangements covering portfolios of assets, association-sponsored programs, and lender-placed structures.

🔧 Under a master policy, the policyholder — typically an employer, association, bank, or program administrator — holds the contract with the carrier, and individual members or certificate holders receive a certificate of insurance evidencing their coverage. This structure streamlines administration: underwriting, premium billing, and endorsement processing happen at the group level, reducing per-unit transaction costs significantly. The master policy spells out the overarching terms, conditions, exclusions, and benefit schedules, while individual certificates may note member-specific details such as coverage amounts or beneficiary designations.

📌 From an operational standpoint, master policies create efficiency for all parties but also concentrate decision-making authority with the policyholder rather than the individual insureds. This distinction carries regulatory implications — particularly around disclosure obligations and the duty to inform certificate holders of their rights. In delegated-authority programs, an MGA or program administrator often manages the master policy on the carrier's behalf, handling everything from binding to claims and renewal, making the governance framework and binding authority agreement especially critical.
