## What Is Professional Errors and Omissions (E&O) Insurance?

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [12](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [13](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [14](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [15](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in Professional Liability (E&O) Insurance

### Profession-Specific Products Versus One Product

Travelers offers separate E&O products by profession: accountants, design professionals, lawyers, real estate professionals, insurance professionals, managed care organizations, financial institutions, and a miscellaneous option for other client-facing professionals. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") At-Bay instead sells one named Miscellaneous Professional Liability product across the revenue sizes it accepts, without splitting eligibility by named profession. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")

### Who Underwrites Versus Who Distributes

Travelers underwrites errors and omissions insurance itself, naming Travelers Casualty and Surety Company of America and its property-casualty affiliates in the E&O page's footer disclosure. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") At-Bay distributes MPL through its own disclosed producer, At-Bay Insurance Services LLC, and its current MPL page does not name the insurer that would carry the risk. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [4](https://www.at-bay.com/licenses/ "Licenses")

### How You Reach a Quote

Travelers directs buyers to talk to an independent agent to place E&O coverage. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") At-Bay instead routes MPL submissions through email or its Broker Platform, a workflow of creating, customizing, and binding a quote. [6](https://www.at-bay.com/brokers/platform/ "Broker Platform")

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

- Ask Travelers which of its nine named profession-specific products applies to your business. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)")
- Confirm the exact Travelers entity on your declarations, since the footer disclosure names Travelers Casualty and Surety Company of America and its affiliates generally. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)")
- Ask At-Bay directly which insurer would issue your MPL policy. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Ask At-Bay for its published $5 million limit ceiling and applicable state restrictions. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Ask Travelers for its limit and retention amounts, since the reviewed E&O page does not publish them. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)")

## Offering Details

| Criteria | At-Bay Miscellaneous Professional Liability (MPL) Insurance | Travelers Errors and Omissions Insurance |
| --- | --- | --- |
| 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..) | Travelers underwrites errors and omissions insurance as one of several management and professional liability products, sold as a standalone policy written for the buyer's profession rather than bundled with other lines by default. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") [11](https://www.travelers.com/business-insurance/professional-liability-insurance "Management and Professional Liability Insurance") (Evidence: Company-reported; scope: E&O and management-liability product pages, as read on 2026-09-23..) |
| 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..) | The E&O page's footer names Travelers Casualty and Surety Company of America and its property-casualty affiliates, but Travelers also states the material does not amend any issued policy, so the exact issuing entity for a given E&O product depends on the policy. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") (Evidence: Company-reported; scope: Footer disclosure on the errors-and-omissions page..) |
| 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..) | Travelers offers separate E&O products by profession, including accountants, design professionals, lawyers, real estate professionals, insurance professionals, life/accident/health insurance agents, managed care organizations, financial institutions and a miscellaneous professional liability option for other client-facing professionals. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") (Evidence: Company-reported; scope: Product-selection list on the E&O page..) |
| 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..) | Travelers describes E&O as covering the costs of client allegations of inadequate work, negligent actions or failure to meet the expected level of service, including legal defense and settlement costs, and says coverage can be customized to the risks of a specific profession. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") (Evidence: Company-reported; scope: E&O overview and video transcript; exclusions and limits are not detailed on this page and depend on the policy as issued..) |
| 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 reviewed E&O page does not publish limit or retention amounts for any of its professional-liability products. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") (Evidence: Not publicly disclosed; scope: Errors-and-omissions page as read on 2026-09-23..) |
| 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..) | Travelers directs buyers to talk to an independent agent to place E&O coverage, and tells agents to use its management-and-professional-liability applications and forms library. [10](https://www.travelers.com/business-insurance/professional-liability-insurance/errors-omissions "Errors and Omissions Insurance (E&O)") [11](https://www.travelers.com/business-insurance/professional-liability-insurance "Management and Professional Liability Insurance") (Evidence: Company-reported; scope: E&O page CTA and video transcript..) |
