  • Dean E. Carberry

    Reinsurance Broking

    Dean has served as an insurance and reinsurance broker for almost thirty years. He joined Greig Fester Ltd. UK (later became Benfield Greig and ultimately Aon Benfield) in 1989 where he was ultimately responsible for the Caribbean Reinsurance Division, servicing existing clients and generating new property and casualty treaty reinsurance clients throughout the region. Caribbean insurers back then had small balance sheets with significant hurricane and earthquake catastrophe exposures and were dependent on significant reinsurance placements to protect their assets.

    In 1996 Dean moved to Cooper Gay & Company UK to develop a treaty reinsurance platform. During this time he was awarded the flag broker position for the General Insurance Corporation of India and their affiliated companies at home and abroad. Additionally, he produced a book of Caribbean treaty reinsurance placements, and also had oversight of several placements for Saudi Arabia, Turkey and Latin America.

    In 2001 he moved to Rattner Mackenzie Ltd, at that time, a Houston Casualty Company under the leadership of Mr. Way. After a year of significant production success Dean was sent to Bermuda to establish Rattner Mackenzie (Bermuda) Ltd. as President & CEO. Rattner Mackenzie (Bermuda) Ltd set up a significant footprint in Bermuda. Rattner Mackenzie Bermuda provided broking services to Houston Casualty Company related businesses as well as developing non related reinsurance opportunities for Rattner Mackenzie Ltd. Under Dean’s leadership Rattner Mackenzie Bermuda were appointed reinsurance brokers and consultants on a number of significant property catastrophe reinsurance placements for several large US Property and Casualty insurance companies, as well as several significant A&H placements, workers’ compensation and general casualty programs.

    This was also a stage in the market when property catastrophe retrocession quota share agreements were in demand and Rattner Mackenize Ltd. were at the forefront of these placements. They were a prelude to the development of “side car” capacity development anticipating the advance of capital markets to the insurance industry.

    After the sale of Rattner Mackenzie Ltd. to Guy Carpenter, Dean moved to the BMS Group to restructure their Bermuda platform and generate business including property catastrophe retrocession business, numerous ILW placements, international reinsurance placements as well as a number of significant loss portfolio transfers and programs throughout the US and Canada. Towards the end of his term at BMS Dean introduced capital investors to numerous insurance Carriers and MGAs and consulted to these companies.

    In May 2015 Dean, in partnership with Atlantic Security Limited (ASL), completed a management buyout of the BMS Bermuda book of business and continues to service and develop that book today. The resulting formation of Atlantic Security Reinsurance Brokers Ltd (ASRB) has developed and rolled out several new products in the USA and Canada with major carriers in these territories, supported by reinsurance. The joint venture has generated significant synergy with ASL’s captive management operations with ASRB referring clients to ASL for management services and ASL referring reinsurance opportunities to ASRB. ASRB has also been focused on the development of credit wrap insurance on various asset types where ASRB can introduce capital investment through SPV’s and where those vehicles are wrapped by insurance products.
