Areas of coverage

At-Bay

  • role: 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. Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk.company-reportedSource ↗Source ↗
  • 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 A September 2023 press release named United Specialty Company in connection with MPL, but that historical reference does not establish the current issuing insurer for a new MPL quote. 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.not-foundSource ↗Source ↗
  • eligibility: 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. Current MPL appetite paragraph; the linked appetite guide's specific eligibility requirements were not independently opened for this record.company-reportedSource ↗
  • coverage: 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. 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.company-reportedSource ↗
  • limits: At-Bay publishes an MPL limit ceiling of up to $5 million, with state restrictions that are not detailed on the product page itself. Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant.company-reportedSource ↗
  • application: 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. Current submission instructions and the general broker-platform workflow description; MPL-specific automation details were not separately confirmed.company-reportedSource ↗Source ↗

Berkshire Hathaway Specialty Insurance

  • coverage: BHSI’s U.S. Professional First overview identifies Lawyers Professional Liability and Miscellaneous Professional Liability alongside Technology E&O and Media Liability. Portfolio catalogue statement; the specific legal/professional class and form must be selected rather than treating the offerings as one policy.company-reportedSource ↗Source ↗
  • eligibility: The overview names staffing firms, management consultants, marketing firms and real-estate firms as targeted customers for Miscellaneous Professional Liability; it separately lists law-firm size bands for Lawyers Professional Liability. U.S. Professional First target statements; class-specific eligibility only.company-reportedSource ↗
  • coverage: For architects, engineers and consultants, BHSI describes a professional-liability form that also addresses pollution, media, technology and cyber/network-security exposures. This is a specialized design-industry combined form, not generic E&O wording or proof that all risks receive each component.company-reportedSource ↗
  • services: The Professional First overview describes its in-house claims handling group as experienced in complex, high-value claims and integrated with underwriting. Company-reported portfolio-level claim-service description, not independently measured claims performance.company-reportedSource ↗
