Umbrella Premiums reflect the actual premiums paid for coverage in excess of a deductible, claim-service, primary insurance policy. This policy insures all divisions for losses that exceed the primary insurance deductible amount in the policy year. Because premiums are related to Corporate sales, and because all divisions have the potential of a catastrophic type loss, this cost will be allocated on adjusted sales (corporate sales less aircraft glass products, which are covered under a separate policy).
