Insurance mergers and acquisitions rarely raise red flags with U.S. national security watchdogs. China's Fosun International Ltd (0656.HK) took that history to heart last year when it paid $1.84 billion for the remaining 80 percent stake of U.S. property and casualty insurer Ironshore Inc that it did not already own.
But in December 2015, one month after Fosun completed the acquisition, it was approached by officials at the Committee on Foreign Investment in the United States (CFIUS), a government panel that scrutinizes deals over national security concerns, according to people familiar with the matter who asked not to be identified because these details are not public.
CFIUS was concerned about how Fosun would operate Ironshore's Wright & Co, a provider of professional liability coverage to U.S. government employees such as law enforcement personnel and national security officials, including the Central Intelligence Agency, according to these sources.
