Key Differences in Crime Insurance
Product scope and audience
AIG describes a crime product for commercial and government entities and links a sample policy. Marsh McLennan Agency lists crime and fidelity within its executive and professional liability practice for organizations seeking those solutions, but its overview does not itemize crime events. Ask MMA for the specific form and covered loss schedule, then compare it with AIG's sample. 3 6 6
