RICHMOND, Va., Oct. 17, 2012 /PRNewswire/ -- Markel Corporation (NYSE: MKL) announced today that it has entered into a definitive agreement to acquire Essentia Insurance Company from OneBeacon Insurance Group LLC. Completion of the transaction is subject to customary closing conditions, including regulatory approval of the change of control of Essentia, and is expected to occur in January 2013. Terms of the transaction were not disclosed. Essentia Insurance Company will continue to underwrite insurance exclusively for Hagerty Insurance Agency and Hagerty Classic Marine Insurance Agency throughout the United States. Hagerty is the leading insurance provider for classic vehicles in the world and host to the largest network of classic car owners. Hagerty offers insurance for classic cars, vintage boats, motorcycles and related automotive collectibles. Hagerty remains a privately-owned, family business. The transition is intended to be seamless for existing Hagerty customers and agents. Both groups will continue to enjoy the same specialized products, service offerings and claim handling. Insurance agents will continue to work with Hagerty as they traditionally have. "Our new relationship with Markel is a natural fit because we are both exclusively focused on specialty and niche insurance markets and are dedicated to providing the best protection to all types of collector vehicles," said McKeel Hagerty, CEO of Hagerty Insurance. "This new relationship will allow us to continue to grow and develop new efficiencies to benefit our clients." Mike Crowley, Markel's President & Co-Chief Operating Officer, added, "We are looking forward to this new partnership.
