Key Differences in Crime Insurance

Combined Package or Placement Across Carriers

Liberty Mutual includes crime in ProShield, a package policy that combines several management-liability coverages. Marsh’s financial and professional liability practice places commercial crime with insurers whose definitions and extensions differ by carrier. A buyer seeking a bundled management-liability policy can compare ProShield’s structure with Marsh’s proposed form and insurer, rather than treating the two descriptions as identical products. 3 8 8

Social-Engineering Limits and Higher Layers

Marsh says it can arrange infill or top-up social-engineering coverage above an existing program, which may matter when a company’s primary crime limit is already committed. Liberty Mutual’s overview lists computer fraud among ProShield’s crime examples but does not describe a social-engineering extension. Ask how each quote defines fraudulent instructions and whether the additional Marsh layer attaches above your existing retention and limit. 8 3

Published Placement Scale

Marsh reports experience with complex placements around $10 million to $110 million, but does not publish a standard limit for an individual buyer. Liberty Mutual likewise leaves specific ProShield limits and deductibles to policy terms. The reported Marsh range signals experience with larger placements; it is not a promise that a particular company will qualify for that amount. 8 3

What to Confirm in Crime Insurance Quotes

  • Ask Marsh for the issuing insurer, primary limit, retention, and exact attachment point and wording for any social-engineering top-up. 8 8 8
  • Ask Liberty Mutual for ProShield’s crime limit, deductible, and any separate sublimit for computer fraud or fraudulent transfers. 3
  • Compare the carriers’ definitions of employee dishonesty and third-party fraud before assuming the package and brokered forms respond the same way. 8 3
