1. What is professional liability insurance (errors and omissions, E&O)?
  1. A Coverage for criminal acts
  2. B Workers compensation for professionals
  3. C Coverage protecting professionals against claims of negligent performance of professional services — covers errors, omissions, mistakes, and failure to meet the standard of care of their profession
  4. D Coverage for office equipment

Explanation

Professional Liability — also called Errors and Omissions (E&O) or Malpractice depending on the profession — protects professionals against claims that negligent performance of their services caused financial loss to a client. Common professions covered: medical professionals (medical malpractice), lawyers (legal malpractice), accountants (accountants E&O), real estate agents, insurance producers, architects and engineers, IT consultants, financial advisors. CGL excludes professional services liability, so professionals need separate E&O coverage. Most professional liability policies are claims-made (triggered when the claim is filed, not when the negligent act occurred), with retroactive dates and tail coverage requirements. Premiums vary widely by profession — surgeons and OB/GYNs pay much more than primary care physicians; trial attorneys pay more than transactional attorneys. Coverage limits typically include defense costs (which can be enormous in professional liability claims).

2. What does professional liability insurance (errors and omissions, or E&O) cover?
  1. A Damage to the insured's building
  2. B Employee injuries
  3. C Physical injuries on the premises
  4. D Claims arising from the insured's professional services — alleged errors, omissions, negligence, or failure to perform professional duties properly (e.g., for accountants, agents, consultants)

Explanation

PROFESSIONAL LIABILITY (Errors & Omissions / E&O): Covers claims arising from the insured's PROFESSIONAL SERVICES — alleged ERRORS, OMISSIONS, NEGLIGENCE, or FAILURE TO PERFORM professional duties to the expected standard.

Examples: An accountant makes an error causing a client financial loss; an insurance agent fails to obtain proper coverage; a consultant gives faulty advice; a real estate agent's error harms a client.

Malpractice: Medical malpractice is professional liability for healthcare providers; vs GENERAL LIABILITY: CGL covers bodily injury/property damage (slips, falls, accidents); E&O/professional liability covers FINANCIAL HARM from professional mistakes (not bodily injury); usually CLAIMS-MADE policies (note retroactive dates and tail coverage); REQUIRED/RECOMMENDED for: professionals whose advice/services could cause clients financial harm; professional liability/E&O is a distinct casualty line covering the financial consequences of professional errors — important exam content distinguishing it from general liability (which covers bodily injury and property damage rather than professional mistakes).
