&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;📋 &amp;#039;&amp;#039;&amp;#039;Professional liability insurance (E&amp;amp;O)&amp;#039;&amp;#039;&amp;#039; 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&amp;amp;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.&lt;br /&gt;
&lt;br /&gt;
⚙️ 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&amp;#039;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&amp;amp;O risks by examining the applicant&amp;#039;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.&lt;br /&gt;
&lt;br /&gt;
💡 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&amp;amp;O limits, and [[Definition:Lloyd&amp;#039;s of London | Lloyd&amp;#039;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&amp;amp;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&amp;amp;O and [[Definition:Cyber insurance | cyber liability]] continues to blur, pushing underwriters to refine policy language and driving demand for hybrid products.&lt;br /&gt;
