Key Differences in Management Liability Insurance

Program Scope and Structure

Aon says its professional-services practice designs management-liability programs for partnerships, but the reviewed overview does not describe a package structure. CNA names D&O, employment practices, fiduciary, fidelity/crime and kidnap/ransom/extortion in its portfolio, and says agents can build a modular mix through Epack 3. That gives buyers a named configuration route to discuss with CNA; ask Aon to show how its recommended program assembles comparable parts for your partnership. 3 7

Access, Terms and Fit

The audiences also differ in scope: Aon identifies law, accounting and consulting firms, while CNA discusses public and private companies, nonprofits and smaller businesses. CNA sends agents to Agent Center for applications; Aon describes professional-services advisors supporting risk decisions. Neither record gives quote-level terms. Ask both to state which coverages are selected, who issues each policy, and whether one event could affect limits across the package. 3 7

What to Confirm in Management Liability Insurance Quotes

  • Ask CNA's agent to itemize Epack 3 modules and explain how limits interact across them. 3 7
  • Ask Aon to identify the issuing carriers and coverage parts proposed for your professional partnership. 3 7
