Light Brokerage

Our Light Brokerage solution can provide coverage for tough-to-place risks that are not large or complex enough to meet traditional brokerage market premiums. This insurance coverage offers a unique appetite that is different from Contract Bind, while still complementing those products. Light Brokerage is submit-only, and each risk is underwritten in-house by our experienced staff, who review, evaluate, endorse, and issue policies.

Inland Marine

Our Inland Marine coverage can protect assets (material, products, equipment) that move or are transportable over land. This insurance solution can also cover these assets while temporarily being stored by a third party. Nautilus writes a wide range of Inland Marine solutions that complement our Property and General Liability offerings.

Products and services described above are provided through various surplus lines insurance company subsidiaries of W. R. Berkley Corporation and offered through licensed surplus lines brokers. Not all products and services may be available in all jurisdictions, and the coverage provided by any insurer is subject to the actual terms and conditions of the policies issued. Surplus lines insurance carriers do not generally participate in state guaranty funds and insureds are therefore not protected by such funds.
