NEW YORK ( The Deal) -- Shuanghui International Holdings is expected to receive clearance from national security regulators for its planned $7.1 billion acquisition of Smithfield Foods ( SFD). An announcement of the approval could come from the companies as early as Friday. The investigation of the deal by the Committee on Foreign Investment in the U.S. is scheduled to close Friday. China-based Shuanghui announced Tuesday that it had put in place $4 billion in debt financing for the acquisition, a clear indication that the company is confident that it will win CFIUS approval. Smithfield revealed on July 24 that CFIUS had extended its review of the deal from the initial informal 30-day review to a second-phase, 45-day investigation that would run through Sept. 6.
