Key Differences in Professional Liability (E&O) Insurance

What Each Publishes on Limits

Coterie publishes each-claim limit options from $25,000 to $1,000,000, with the aggregate set at two to three times the each-claim limit. 8 Chubb instead says Pro ERM covers 100% of defense costs for covered claims worldwide, without publishing a separate liability limit figure. 3

Extending Coverage After the Policy Ends

Coterie's base MPL policy includes a 60-day extended reporting period, with optional purchased extensions of one to six years and up to six years of prior-acts coverage. 8 Chubb's reviewed Pro ERM page does not describe an extended reporting period or retroactive-date structure. 3

Where Coverage Is Actually Available

Coterie says MPL is currently unavailable in the District of Columbia, Illinois, Massachusetts, Montana, North Dakota and Virginia. 8 Chubb's reviewed page names target clients and product features for Pro ERM but does not mention state-level availability restrictions. 3

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

  • Ask Coterie to confirm coverage is actually available in your state before relying on its published limits. 8
  • Confirm Chubb's actual liability limit for Pro ERM, since the reviewed page names defense-cost treatment but not a limit figure. 3
  • Ask Chubb whether tail or extended-reporting coverage is available for Pro ERM, since its page does not describe the option. 3
  • Get the issuing insurer for Coterie's MPL; its brochure names only a policy form code, not the carrier. 8
