&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;⚖️ &amp;#039;&amp;#039;&amp;#039;Error and omission (E&amp;amp;O)&amp;#039;&amp;#039;&amp;#039; is a form of [[Definition:Professional indemnity insurance | professional liability insurance]] that protects individuals and firms against claims alleging negligent acts, errors, or omissions in the performance of professional services. Within the insurance industry, E&amp;amp;O coverage carries particular significance in two directions: insurers and [[Definition:Reinsurance | reinsurers]] underwrite E&amp;amp;O policies for a wide range of professional classes (lawyers, accountants, architects, technology consultants), and insurance intermediaries — [[Definition:Insurance broker | brokers]], [[Definition:Insurance agent | agents]], [[Definition:Managing general agent (MGA) | MGAs]], and [[Definition:Third-party administrator (TPA) | TPAs]] — are themselves required to carry E&amp;amp;O coverage as a condition of licensure or market access in virtually every major jurisdiction. The term &amp;quot;E&amp;amp;O&amp;quot; is most commonly used in North American markets; in the United Kingdom and many international markets, the equivalent product is typically called [[Definition:Professional indemnity insurance | professional indemnity (PI) insurance]], though the underlying coverage concept is substantially similar.&lt;br /&gt;
&lt;br /&gt;
🔍 E&amp;amp;O policies are almost universally written on a [[Definition:Claims-made policy | claims-made]] basis, meaning coverage responds to claims first made during the policy period regardless of when the underlying error occurred — provided it falls within the retroactive date. A typical policy covers defense costs, settlements, and judgments arising from allegations of professional negligence, but commonly excludes intentional misconduct, bodily injury, and criminal acts. For insurance intermediaries specifically, E&amp;amp;O claims often stem from failure to procure requested [[Definition:Insurance coverage | coverage]], misrepresentation of policy terms, failure to advise on adequate [[Definition:Limit of liability | limits]], or administrative errors that leave clients uninsured at the time of a [[Definition:Loss | loss]]. [[Definition:Underwriting | Underwriting]] E&amp;amp;O for intermediaries involves evaluating the firm&amp;#039;s lines of business, revenue, claims history, internal quality controls, and compliance procedures. Regulatory bodies — including [[Definition:Lloyd&amp;#039;s of London | Lloyd&amp;#039;s]] for its [[Definition:Coverholder | coverholders]], state insurance departments in the U.S., and the Financial Conduct Authority in the UK — set minimum E&amp;amp;O coverage requirements that vary by role and market.&lt;br /&gt;
&lt;br /&gt;
🛡️ Maintaining adequate E&amp;amp;O coverage is not merely a regulatory checkbox — it is a foundational element of professional credibility and client trust in the insurance distribution chain. When a [[Definition:Policyholder | policyholder]] suffers a loss that should have been covered but was not, due to a broker&amp;#039;s or agent&amp;#039;s mistake, the E&amp;amp;O policy serves as the financial backstop that makes the client whole. Without it, the intermediary faces personal or corporate liability that can be existential for smaller firms. For insurers writing E&amp;amp;O across professional classes, this line has grown in importance as the complexity of professional services increases and litigation trends expand the scope of actionable negligence. [[Definition:Cyber insurance | Cyber]]-related E&amp;amp;O claims — where technology firms face allegations that software defects or service failures caused client losses — have emerged as one of the fastest-growing segments, blurring the line between traditional E&amp;amp;O and technology liability coverage.&lt;br /&gt;
