Captive Insurance
Group captives are ideal for companies with over $150,000 in annual premiums across workers’ compensation, general liability, and auto insurance. By creating a captive, businesses can assess the risks of subsidiaries, write policies, set premiums, and potentially earn back up to 60% of premiums in profits or invest for future claims. Some captives also insure the risks of their group’s customers. Benefits include:
- Protection similar to a traditional, guaranteed cost plan.
