1. DESCRIPTION OF BUSINESS

Enstar Group Limited ("Enstar") is a Bermuda-based holding company, formed in 2001. Enstar is a multi-faceted insurance group that offers innovative capital release solutions and specialty underwriting capabilities through its network of group companies in Bermuda, the United States, the United Kingdom, Continental Europe, Australia, and other international locations. Our ordinary shares are listed on the NASDAQ Global Select Market under the ticker symbol "ESGR". Unless the context indicates otherwise, the terms "Enstar," "we," "us" or "our" mean Enstar Group Limited and its consolidated subsidiaries and the term "Parent Company" means Enstar Group Limited and not any of its consolidated subsidiaries.

Our business is organized into three segments:


(i)	Non-life Run-off: This segment comprises the operations of our subsidiaries that are running off their property and casualty and other non-life business. It also includes our management business, which manages the run-off portfolios of third parties through our service companies;

(ii)

Atrium: Atrium Underwriters Ltd. is a managing general agent at Lloyd’s of London ("Lloyd's"), which manages Syndicate 609. Through a corporate capital vehicle, Atrium 5 Ltd., we provide 25% of the syndicate’s underwriting capacity and capital (with the balance provided by traditional Lloyd’s Names). Atrium specializes in a wide range of industry classes, including marine, aviation and transit, property and casualty binding authorities, reinsurance, accident and health and non-marine direct and facultative; and


(iii)	StarStone: StarStone is a global specialty insurer that underwrites a diverse range of property, casualty and specialty insurance through its operations in Bermuda, the United States, the United Kingdom, and Continental Europe. Certain business of StarStone placed into run-off at the time of our acquisition of StarStone is recorded in our Non-life Run-off segment.

Atrium and StarStone, our active underwriting operations, are reported as separate segments because they are managed and operated in separate and distinct manners. Atrium employees are not involved in the management or strategy of StarStone, nor are StarStone employees involved in the management or strategy of Atrium. Atrium and StarStone are monitored and reported upon separately and distinctly and their strategies and business plans are determined independently of each other.

In addition to our three reportable segments, our other activities, which do not qualify as a reportable segment, include our corporate expenses, debt servicing costs, holding company income and expenses, foreign exchange and other miscellaneous items.
