No, do not cancel your existing business casualty policies. They are still important for your protection and management of your business risks. Coverage provided by the supplemental casualty insurance and reinsurance will complement your commercial business casualty policies. The supplemental insurance can fill the gaps arising from deductibles, exclusions, and limitations of your regular commercial policies. It would be patently inappropriate to cancel your commercial coverage for the sole purpose of inflating premiums to a captive insurer for the same coverage.
