# Mayflower Specialty: AI liability coverage summary

Last updated: October 5th 2026. Canonical page: https://mayflowerspecialty.com/coverage

Mayflower Specialty is an AI liability insurance specialist that provides coverage for companies that build and deploy AI. It writes affirmative AI coverage for directors and officers liability (AI-D&O), employment practices liability (AI-EPL) and professional liability (AI-E&O), plus an AI DIC Excess layer over an existing program, on A- (Excellent) AM Best rated paper backed by some of the world's largest reinsurers. Coverage is placed through brokers and underwritten on the applicant's AI governance.

## Modules

- **AI Directors and Officers Liability (AI-D&O)** is written for claims against directors and officers arising from the company's use, oversight or disclosure of AI, such as securities and derivative claims alleging AI-washing or failed oversight.

- **AI Employment Practices Liability (AI-EPL)** is written for employment claims arising from AI used in hiring, promotion, discipline and other workforce decisions, such as discrimination claims over automated screening. Details: https://mayflowerspecialty.com/coverage/ai-employment-practices
- **AI Professional Liability (AI-E&O)** is written for claims by clients and third parties who suffer a loss from AI-enabled products or services, such as an inaccurate or hallucinated output. Details: https://mayflowerspecialty.com/coverage/ai-errors-and-omissions
- **AI DIC Excess** is a difference-in-conditions layer over an existing D&O, EPL and E&O program that adds affirmative AI coverage where those policies are silent on AI or exclude it. Details: https://mayflowerspecialty.com/coverage/ai-dic-excess

## Structure and policy form

- Coverage is available as a modular primary policy or as a difference-in-conditions layer over an existing D&O, EPL and E&O program.
- The policy is written on a claims made and reported basis: it covers claims first made against the insured during the policy period, or any extended reporting period, and reported as the policy requires.
- Defense costs reduce and may exhaust the limit of liability and are subject to the retention.
- Limits, retentions and premiums are set by underwriting for each applicant and are not published.

## Security

- Policies are written on A- (Excellent) AM Best rated paper and backed by some of the world's largest reinsurers, whose names are confidential.
- Claims are handled by a specialist claims administrator.

## How underwriting and pricing work

Underwriting is based on how the applicant governs its AI. The application asks about these areas:

- Applicant information
- AI systems overview
- AI governance
- Data governance
- System operations and monitoring
- AI incident response
- Regulatory environment and compliance
- Claims and loss history
- Prior and current insurance
- Required documentation
- Applicant representation and warranty

Underwriters weigh, among other things, how many AI systems are in production, how autonomous they are, how material their decisions are to the people affected, whether generative AI or agents are in use, the governance and oversight around them, data governance, monitoring and incident response, regulatory exposure and claims history. Stronger governance can earn broader terms and better pricing, although no pricing figures are published.

## Required documents

- Completed ACORD application(s) for the applicable coverage lines
- Three years of loss runs for D&O, EPL and E&O
- Most recent annual financial statements or audited financials
- AI governance policy or responsible AI framework
- AI system inventory (systems, use cases and data types)

## Outside underwriting appetite

- autonomous weapons or military targeting
- social scoring or mass surveillance
- biometric identification in public spaces
- real-time emotion inference in workplace or educational settings
- deepfake generation without disclosure
- Predictive policing and criminal sentencing applications are considered only on bespoke terms.
