A fidelity bond is a form of insurance that protects employee benefit plans from losses due to fraudulent acts by individuals handling plan assets. ERISA requires plans to purchase a fidelity bond of at least 10% of plan assets up to $500,000. Anyone with access to plan assets, including employees and service providers, must be covered. Plans report bond coverage on Form 5500 to allow the Department of Labor to monitor compliance. A plan fiduciary can be liable for losses if proper bonding is not maintained.
