Top 25 Terms You Must Know for the E&O Insurance Exam

Mastering the Errors and Omissions (E&O) insurance exam requires more than just a general understanding of insurance principles; it demands a precise grasp of professional liability vocabulary. Unlike standard property and casualty forms, E&O policies are often non-standardized and highly specialized based on the profession being insured.

This guide breaks down the top 25 essential terms you will encounter on the exam. Understanding these definitions is critical for navigating questions regarding policy triggers, coverage limitations, and legal obligations. For a broader overview of the testing process, refer to our complete E&O exam guide or start testing your knowledge with practice E&O questions.

• Professional Liability: A broad category of insurance designed to protect professionals (such as doctors, lawyers, and insurance agents) against claims of negligence or failure to perform professional duties.
• Negligence: The failure to exercise the degree of care that a reasonably prudent person (or professional) would exercise in similar circumstances.
• Error: An affirmative act or mistake made by a professional during the course of providing services.
• Omission: A failure to perform an act that should have been performed, resulting in a loss for the client.
• Duty of Care: The legal obligation of a professional to provide services that meet the standard of care established within their specific industry.

Timing is everything in E&O insurance. Most professional liability policies are written on specific forms that differ significantly from General Liability (GL) policies.

• Claims-Made Form: A policy type that provides coverage only if the claim is made against the insured and reported to the insurer during the policy period.
• Retroactive Date: A date specified in the declarations page; the policy will not cover claims resulting from acts that occurred before this date.
• Extended Reporting Period (ERP): Also known as "Tail Coverage," this allows the insured to report claims after the policy has expired, provided the act occurred during the policy period.
• Prior Acts Coverage: An endorsement or provision that covers claims arising from acts that occurred before the current policy's inception date but after the retroactive date.
• Continuity Date: The date from which an insured has maintained continuous claims-made coverage without a gap.
• Pending or Prior Litigation (P&P) Date: A date used to exclude any claims or circumstances that were already in litigation or known to the insured prior to a certain point.
• Full Prior Acts: A policy that does not have a retroactive date, meaning it covers any act regardless of when it occurred, as long as the claim is made during the policy period.

• Aggregate Limit: The maximum amount the insurer will pay for all claims combined during a single policy period.
• Per Claim Limit: The maximum amount the insurer will pay for any single claim, regardless of the number of claimants.
• Defense Costs Inside the Limits: A provision where legal fees and defense expenses reduce the available limit of liability for paying settlements or judgments.
• Self-Insured Retention (SIR): A dollar amount that must be paid by the insured before the insurance policy responds to a loss.
• Hammer Clause: A provision that limits the insurer’s liability if the insured refuses to settle a claim as recommended by the insurer. If the insured continues to litigate, they become responsible for costs exceeding the proposed settlement.
• Allocation: The process of determining which portion of a claim or defense cost is covered when a lawsuit involves both covered and non-covered allegations.

• Professional Services: The specific activities defined in the policy for which coverage is provided. If an act falls outside this definition, there is no coverage.
• Vicarious Liability: Liability imposed on a professional for the negligent acts of their employees or agents.
• Indemnification: A contractual agreement where one party agrees to compensate another for losses or damages.
• Duty to Defend: The insurer’s obligation to provide a legal defense for the insured, even if the allegations are groundless, false, or fraudulent.
• Right to Settle: The insurer’s authority to settle a claim without the express consent of the insured (though many E&O policies require consent).
• Bodily Injury/Property Damage Exclusion: A standard exclusion in E&O policies, as these risks are typically covered under General Liability insurance.
• Contractual Liability: Liability that an insured assumes through a contract; this is often excluded in E&O policies unless the liability would have existed anyway under common law.
