Are you referring to insurance coverage for the Bank - ie if there's a fire in branch A, is the Bank adequately covered? Credit life and disability are completely different.
If so, a few things to look at are to see if the Bank is adeqautely insured (equipment, buildings, etc), see if they're meeting contractual covenants per the policies, review the claims process and the controls therein, and is an annual report presented to the Board. Those are a few off the top of my head.
