Key Differences in Fiduciary Liability Insurance
A wholesale platform module versus a combined policy
Cowbell distributes Zurich’s fiduciary module through appointed Zurich E&S wholesalers using an API; it is not sold directly to businesses. Liberty Mutual includes fiduciary liability in ProShield for private and nonprofit organizations. Buyers should account for Cowbell’s wholesale access route and compare its module with Liberty Mutual’s packaged eligibility. 4 7
Company-size criteria and coverage detail
Cowbell targets private companies under 250 employees and $50 million in assets, and describes coverage for benefit-plan fiduciary breaches. Liberty Mutual describes fiduciary and plan-sponsor protection but does not set a company-size threshold in the reviewed record. Ask for underwriting eligibility and forms for your plan. 4 7
