E&O vs. General Liability: Key Differences for the Exam

When preparing for the Errors and Omissions (E&O) exam, one of the most fundamental concepts you must master is the distinction between Commercial General Liability (CGL) and Professional Liability (E&O). While both are liability policies designed to protect a business from third-party claims, they cover vastly different exposures.

The CGL policy is often considered the 'foundational' coverage for a business, protecting against the physical risks of operating. In contrast, E&O insurance protects against the intangible risks associated with professional advice, service, and expertise. Understanding where one ends and the other begins is a frequent subject of exam questions. For a broader overview of the subject, see our complete E&O exam guide.

One of the most critical points for exam candidates is the Professional Services Exclusion found in most standard CGL policies. This exclusion is the reason E&O exists as a separate line of insurance. If a doctor performs surgery and makes a mistake, the resulting injury is technically 'bodily injury,' but the CGL policy will likely deny the claim because the injury arose from a 'professional service.'

To successfully navigate practice E&O questions, you must remember that CGL policies are designed for 'premises and operations' liability. If a client trips over a rug in an architect's office, that is a CGL claim. If that same architect designs a building that collapses due to a math error, that is an E&O claim.

• CGL: Covers the 'office space' and 'physical presence.'
• E&O: Covers the 'intellectual output' and 'professional judgment.'

In the insurance world, Bodily Injury (BI) and Property Damage (PD) are the domains of General Liability. Most E&O policies specifically exclude BI and PD unless they are inherent to the profession (such as medical malpractice). Instead, E&O focuses on pure economic loss.

Consider a financial advisor who gives poor investment advice. The client didn't break a leg or have their car damaged; they lost money in their bank account. Since there is no physical damage, a CGL policy provides no coverage. The E&O policy is triggered specifically because the loss is financial in nature, resulting from the professional's failure to meet the expected standard of care.

Another nuance often tested is how legal defense costs are handled. In a standard CGL policy, defense costs are typically 'supplementary payments' and are paid in addition to the policy limits. This means if a business has a $1 million limit, the insurer could spend $200,000 on lawyers and still have $1 million left to pay a settlement.

In E&O insurance, defense costs are frequently 'within the limits' (also known as 'self-consuming' or 'eroding' limits). If the same $1 million policy spends $200,000 on defense, only $800,000 remains to pay the actual claim. Candidates should be alert for this distinction in scenarios involving high-litigation professional fields.
