About Excess and Surplus (E&S) Lines Insurance
Nautilus Insurance Group is a leading U.S. Commercial Excess and Surplus Lines provider, specializing in the high-volume, small-premium market.
What is Excess and Surplus (E&S) Lines Insurance?
The Excess and Surplus Lines Market is an insurance marketplace established for the purpose of insuring unique or hard-to-place risks. The Excess and Surplus Lines market enables businesses and consumers to get insurance they can’t in the standard market. Because regulations and laws limit the ability of Excess and Surplus Lines insurers to market directly to consumers, Excess and Surplus Lines insurance is sold through licensed Surplus Lines producers. While Surplus Lines insurers are subject to regulation, they cannot participate in state insurance guaranty funds.


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.
