Lumbermens Mutual Casualty Company sold the Company on September 30, 2003, to SeaBright Insurance Holdings, Inc., which was organized and funded by Summit Partners, a leading global private equity and venture capital firm, and the former senior executives of Eagle Insurance Companies. The purchase included the transfer of Eagle's staff, selected assets and the renewal rights to all Eagle Insurance Companies business.
