## 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. [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://www.travelers.com/business-insurance/professional-liability-insurance/apps-forms/crime-non-financial-institutions "Crime Non-Financial Applications and Forms") [10](https://asset.trvstatic.com/download/assets/cri-3001.pdf/98f30f1063c911eeb2f1deb19c93b21f "Crime Terms and Conditions") [11](https://www.chubb.com/us-en/business-insurance/social-engineering-fraud-coverage-for-crime-insurance.html "Social Engineering Fraud Insurance") [12](https://asset.trvstatic.com/download/assets/cri-1100w-ind.pdf/9aa2577663c911ee91291279531924d3 "Commercial Crime Coverage Application")

## Key Differences in Crime Insurance

### What the Offering Describes

Lockton lists employee theft, forgery, on- or off-premises theft, computer fraud, counterfeit currency and social-engineering impersonation losses. Marsh McLennan Agency identifies commercial crime and fidelity but its overview does not list insured events. If vendors or employees can authorize payments, ask Marsh McLennan Agency whether the wording covers impersonation and funds sent on fraudulent instructions. [4](https://global.lockton.com/us/en/products-services/crime-and-fidelity-insurance "Crime and Fidelity Insurance") [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### Limits, Eligibility and Handling

Lockton says its Professional and Executive Risk Claims team handles crime and fidelity claims, integrating insurance and claims counsel within its broking team. Marsh McLennan Agency’s product overview does not describe a comparable claims service. A buyer should identify who will help assemble evidence and communicate with the insurer after a discovered loss. [4](https://global.lockton.com/us/en/products-services/crime-and-fidelity-insurance "Crime and Fidelity Insurance") [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### Starting a Crime Placement

Lockton says the line can serve nonprofit, private and public organizations across sectors, while noting financial institutions often need a distinct financial institution bond. Marsh McLennan Agency describes crime for executive-risk buyers without a sector list. If you are a bank or credit union, verify the product type before relying on a general crime quote. [4](https://global.lockton.com/us/en/products-services/crime-and-fidelity-insurance "Crime and Fidelity Insurance") [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

## What to Confirm in Crime Insurance Quotes

- Ask Lockton whether your organization needs a financial institution bond rather than general crime coverage. Ask Marsh McLennan Agency to identify the claims advocate, covered agreements, social-engineering conditions and insurer. [4](https://global.lockton.com/us/en/products-services/crime-and-fidelity-insurance "Crime and Fidelity Insurance") [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")
