Key Differences in Professional Liability (E&O) Insurance

Claims-Made Continuity

HUB says E&O policies are typically claims-made and can include prior acts back to a retroactive date and tail coverage for an extended reporting period; coverage can also extend to independent contractors and temporary staff. CNA describes Epack 3 and EPS Plus as distinct packages; a buyer changing carriers should compare the offered form’s continuity terms with HUB’s listed options. If you are changing carriers or have temporary staff, compare retroactive dates, tail cost, and who qualifies as an insured. 10 5

Broker Placement and Policy Customization

HUB says it customizes E&O placement around business size, industry, location, risk base, and desired limits; it directs prospects to a broker. CNA describes Epack 3 and EPS Plus as different E&O package routes. Ask HUB which insurer will issue the proposed form and ask CNA which product configuration and services definition would be quoted for the same work. 9 4

What to Confirm in Professional Liability (E&O) Insurance Quotes

  • Ask HUB for the retroactive date, tail terms, contractor status, and named insurer. 10
  • Ask CNA which form applies and whether E&O is combined with cyber or media. 4
