Professional Liability and Errors & Omissions

What Professional Liability Covers

Professional liability (also called errors and omissions, E&O) covers financial harm caused by a professional's negligent act, error, or omission in rendering or failing to render professional services. It responds to economic loss - bad advice, a missed deadline, a flawed design - rather than the bodily injury and property damage a CGL handles.

The CGL specifically excludes professional services, which is why accountants, lawyers, architects, engineers, real estate agents, insurance agents, and IT consultants buy separate E&O. Malpractice is the medical-professional version (physicians, dentists, nurses) of the same concept.

Claims-Made vs. Occurrence - The Central Concept

Most professional liability is written claims-made, unlike the CGL which is typically occurrence. The trigger difference is the most tested idea in this entire unit.

A claims-made policy responds only if the wrongful act occurred on or after the retroactive date AND the claim is first reported during the policy period (or extended reporting period).

Retroactive Date and the Extended Reporting Period (Tail)

The retroactive date is the earliest date a covered wrongful act may occur. Any error before that date is excluded forever, even if the claim arrives during the policy period. Maintaining an unbroken retroactive date when switching carriers is critical - a reset retro date creates a gap.

The extended reporting period (ERP), or tail, lets a claim be reported after the policy ends, as long as the act fell within coverage:

• Basic (mini) tail - automatic, short (often 30-60 days)
• Supplemental (full) tail - purchased, may be 1, 3, or unlimited years

Example. A consultant's claims-made policy has a 1/1/2022 retroactive date and expires 1/1/2026. An error made in 2023 generates a lawsuit served in 2026 after expiration. Without a tail, the claim is uncovered; a purchased supplemental ERP would bring it back in.

Defense, Limits, and Common Provisions

E&O policies frequently use defense-within-limits (also called eroding or wasting limits): legal defense costs reduce the available indemnity limit.

Worked example. A lawyer carries a $1,000,000 E&O limit on a defense-within-limits form. Defense costs reach $300,000 and the claim settles for $800,000. The total demanded is $1,100,000, but only $1,000,000 is available - so the insurer pays $300,000 defense plus $700,000 indemnity, and the lawyer personally owes the remaining $100,000. On an outside-the-limits form, the full $800,000 settlement plus separate defense would be paid.

Many E&O forms also include a consent-to-settle (hammer) clause: if the insured refuses a settlement the insurer recommends, the insurer's liability is capped at the recommended amount plus defense to that point.

Exam Traps

• Prior acts / nose coverage: the opposite of tail - a new claims-made policy can cover acts before its inception if it grants full prior-acts (a retro date earlier than inception).
• Punitive damages are commonly excluded or limited by state law.
• E&O does NOT cover intentional/dishonest acts, fraud, or criminal conduct; it covers negligence.
• Bodily injury and property damage belong on the CGL, not E&O; confusing the two is a classic distractor.
• A claims-made-and-reported policy requires the claim be both made and reported in the same period (subject to the ERP).

Who Buys E&O and What Triggers a Claim

E&O is sold by occupation, and the exam expects you to recognize who needs it:

The wrongful act trigger is a negligent act, error, or omission in rendering professional services for others for a fee. A doctor who gives a poor diagnosis triggers malpractice; an insurance agent who fails to bind requested coverage triggers agents E&O. The professional duty must arise from the professional capacity, not from ordinary premises hazards, which is why a slip-and-fall in a law office is a CGL claim, not an E&O claim.

Step Rating and the Mature Claims-Made Policy

Because claims-made coverage grows broader each year (the gap between the retroactive date and the present widens), insurers use step rating. A first-year claims-made policy is cheapest because only a narrow band of acts can mature into claims; premiums step up in years two, three, and four as more prior acts become exposed.

By roughly the fifth year, the policy is considered mature and is priced close to an occurrence policy for the same limits. This explains a common exam point: claims-made coverage is initially less expensive than occurrence, but the savings shrink as the policy matures, and the eventual tail (ERP) purchase carries its own significant cost. Understanding step rating helps you answer questions about why an insured's E&O premium rises even with no claims and no rate increase.
