AIG vs 
Liberty Mutual: How Do They Compare for Crime Insurance?
What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2
What Is Liberty Mutual Business Insurance?
Liberty Mutual spans small-commercial, commercial, specialty, surety, and reinsurance businesses. The insurer and distribution route depend on the product, so check the offer and policy before you compare terms. 4,5
What Is Crime Insurance?
Crime insurance can help reimburse specified business losses from theft and fraud, including employee theft and forgery. Compare those protections separately and ask whether a payment sent after an impersonation scam is covered. 7,8,9,10,11
Key Differences in Crime Insurance
Standalone crime or management-liability package
AIG presents crime insurance as a distinct product for commercial and government entities. Liberty Mutual places crime inside ProShield, a package policy combining multiple management-liability coverages for private and nonprofit organizations. Ask whether your organization can buy the Liberty Mutual crime coverage on its own or only with the package. 3 6 6
How the covered events are described
AIG's summary includes loss of money, securities and other assets from dishonesty, theft or fraud, including computer fraud. Liberty Mutual lists employee dishonesty, embezzlement, safe burglary and computer fraud as ProShield crime exposures, with selected enhancements. Ask for the actual crime insuring agreement and endorsements because Liberty Mutual's listed events are product summaries and AIG says terms vary by policy and state. 3 6
