## Buyer Intent Signals
Problems: high risk commercial property insurance | Self-Insurance / Captive Insurance: Large corporations often set aside capital to self-insure against specific professional or environmental risks rather than buying third-party policies. | Risk Management Consultancies: Risk management firms like Marsh or Aon provide consulting to mitigate risks without necessarily purchasing a specific AIG/Lexington policy.
Solutions: excess and surplus lines insurance providers | environmental liability insurance for corporations | not for profit D&O insurance specialists | cheapest small business professional liability | Standard Commercial Lines: Using general commercial liability policies from standard carriers that may have significant exclusions for specialized risks.
