## What Are the Key Differences Between At-Bay and Marsh McLennan Agency Professional Liability (E&O) Insurance?

### Advertised MPL ceiling and policy features

At-Bay advertises primary MPL limits up to $5 million, subject to state restrictions and applicant eligibility, and lists coverage highlights such as independent contractors and disciplinary-proceeding defense. MMA’s source names E&O alongside architects and engineers and lawyers professional lines. Compare At-Bay’s MPL appetite and listed features with the specialist MMA form proposed for your occupation; neither product label substitutes for the declarations. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### Submission channel and profession fit

At-Bay directs its MPL page to properly licensed insurance professionals and asks for submissions; its separate Broker Platform page describes a general quote-customize-bind workflow, but MPL-specific automation was not separately confirmed. MMA’s source names several professional product categories. If your account is submitted through the platform, confirm with At-Bay whether that workflow applies to this MPL risk, and ask MMA which listed line fits the services being insured. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

## At-Bay vs Marsh McLennan Agency Professional Liability (E&O) Compared

| Criteria | At-Bay Miscellaneous Professional Liability (MPL) Insurance | Marsh McLennan Agency professional errors omissions (official overview) |
| --- | --- | --- |
| Role in This Line | At-Bay markets MPL as one of its own named insurance products, sold through its disclosed producer, At-Bay Insurance Services LLC, with the product page directed at "properly licensed insurance professionals" submitting business rather than at direct retail buyers. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [4](https://www.at-bay.com/licenses/ "Licenses") (Evidence: Company-reported; scope: Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk..) | Marsh McLennan Agency describes arranging professional errors omissions for the audience stated on the cited product page. [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: professional errors omissions marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Issuing Insurer | The current MPL product page does not name the insurer that issues the policy. A September 2023 press release named United Specialty Company in connection with MPL, but that historical reference does not establish the current issuing insurer for a new MPL quote. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [5](https://www.at-bay.com/press_releases/at-bay-doubles-mpl/ "At-Bay Doubles Miscellaneous Professional Liability Appetite") (Evidence: Not found in reviewed sources; scope: Reviewed MPL page as of 2026-09-23 and the September 2023 press release; restates the existing provider fact that MPL's current issuer is unresolved, distinct from the August 2023 Cyber/Tech E&O transition to At-Bay Specialty Insurance Company paper..) | Confirm in your quote. |
| Who It’s For | At-Bay says it provides primary MPL for businesses of all revenue sizes with limits up to $5 million, subject to state restrictions and eligibility requirements detailed in a separate MPL appetite guide. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Current MPL appetite paragraph; the linked appetite guide's specific eligibility requirements were not independently opened for this record..) | Organizations seeking professional liability placement; source does not imply all professions share one policy. [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: professional errors omissions marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Coverage Features | At-Bay lists MPL coverage highlights including automatic coverage for acquired subsidiaries, claims-made-and-reported coverage, coverage for independent contractors, disciplinary-proceedings defense, a duty-to-defend contract, personal-injury coverage (including emotional distress), punitive damages where insurable, a professional-services definition written for each insured, and an 80/20 hammer clause. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Product-page coverage-highlights list; an 80/20 hammer clause is a settlement provision where the insurer pays 80% and the insured pays 20% of costs after the insured declines a recommended settlement. The issued policy and declarations control actual wording, limits and exclusions..) | The cited product page describes E&O and named specialist professional lines, including architects and engineers and lawyers professional liability; the overview does not treat them as one form. Marketing description only; actual coverage, exclusions, conditions, limits, and availability depend on the issued policy and jurisdiction. [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: professional errors omissions marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Limits and Retentions | At-Bay publishes an MPL limit ceiling of up to $5 million, with state restrictions that are not detailed on the product page itself. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant..) | The cited overview does not set a universal limit or retention for this line. Ask for the proposed policy form, limits, retentions, exclusions, and conditions in the quote. [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Not publicly disclosed; scope: Only the cited marketing page was reviewed for published limit and retention information; no policy-form entitlement is inferred..) |
| How to Apply | At-Bay directs MPL submissions to underwriting by email or through automatic quotes on its Broker Platform, which At-Bay describes as a workflow of creating a quote, customizing limits and retentions, and binding the policy. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") (Evidence: Company-reported; scope: Current submission instructions and the general broker-platform workflow description; MPL-specific automation details were not separately confirmed..) | The page invites organizations to contact a Marsh McLennan Agency adviser or specialist to discuss placement. The page does not establish a quote, bind, or coverage-effective timeline. [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: professional errors omissions marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience.
