View source for Definition:Professional liability insurance (E&O)

📋 '''Professional liability insurance (E&O)''' is a [[Definition:Coverage | coverage]] line that protects professionals and their firms against [[Definition:Claim | claims]] arising from errors, omissions, negligent acts, or failures to perform in the delivery of professional services. Often called errors-and-omissions insurance, this product sits at the intersection of [[Definition:Casualty insurance | casualty]] and [[Definition:Specialty insurance | specialty insurance]], covering defense costs and damages when a client alleges financial harm caused by inadequate or faulty professional advice, design, or service. Within the insurance industry itself, E&O policies are essential for [[Definition:Insurance broker | brokers]], [[Definition:Managing general agent (MGA) | MGAs]], [[Definition:Third-party administrator (TPA) | TPAs]], and [[Definition:Claims adjuster | adjusters]], whose professional missteps—such as failing to place adequate [[Definition:Coverage | coverage]] or mishandling a claim—can generate significant legal exposure.

⚙️ The policy typically responds on a [[Definition:Claims-made policy | claims-made]] basis, meaning it covers claims first reported during the active policy period regardless of when the underlying act occurred, subject to a [[Definition:Retroactive date | retroactive date]]. When a [[Definition:Policyholder | policyholder]] receives a demand letter or lawsuit, they notify the [[Definition:Insurance carrier | carrier]], which assigns defense counsel and evaluates the claim against the policy's [[Definition:Insuring agreement | insuring agreement]], [[Definition:Retention | retention]] (the professional liability equivalent of a [[Definition:Deductible | deductible]]), and any applicable [[Definition:Exclusion | exclusions]]. [[Definition:Underwriting | Underwriters]] price E&O risks by examining the applicant's profession, revenue, claims history, contractual obligations, and risk-management practices. Tail or [[Definition:Extended reporting period (ERP) | extended reporting period]] endorsements allow departing professionals or firms that cease operations to report claims discovered after the policy expires.

💡 For the insurance distribution chain, this coverage is more than a commercial product to sell—it is a regulatory and contractual necessity. Many state [[Definition:Department of insurance (DOI) | departments of insurance]] require licensed intermediaries to carry minimum E&O limits, and [[Definition:Lloyd's of London | Lloyd's]] mandates that [[Definition:Coverholder | coverholders]] maintain professional indemnity insurance as a condition of their [[Definition:Binding authority agreement | binding authority agreements]]. Beyond compliance, robust E&O coverage signals credibility to trading partners and clients, often influencing appointment decisions by carriers evaluating prospective [[Definition:Program business | program]] relationships. As professional services become more technology-dependent, the line between E&O and [[Definition:Cyber insurance | cyber liability]] continues to blur, pushing underwriters to refine policy language and driving demand for hybrid products.
