Markel Corporation sells specialty insurance products and programs to a variety of niche markets. The Company competes in three segments of the specialty insurance marketplace: Excess and Surplus Lines (the E&S Market), Specialty Admitted and the London Insurance Market. The E&S Market focuses on hard-to-place risks and risks that admitted insurers specifically refuse to write. In the Specialty Admitted Market, Markel writes business through the Specialty Program Insurance and the Specialty Personal and Commercial Lines units. Specialty Program Insurance focuses on providing total insurance programs for businesses engaged in similar but highly specialized activities. Specialty Personal and Commercial Lines offers its insurance products in niche markets, focusing on watercraft and commercial marine, yacht, motorcycle and property coverages. In the London Insurance Market, the Company writes specialty property, casualty, marine and aviation insurance on a direct and reinsurance basis.
