Except in the case of affiliates described in the preceding sentence, nothing in this subsection shall be construed to authorize any foreign bank or company referred to in this subsection, or any affiliate thereof, to engage in activities authorized by this subsection through the acquis

The authority conferred by this subsection on a foreign bank or other company shall terminate 2 years after the date on which such foreign bank or other company becomes a “bank holding company” as defined in section 2(a) of the Bank Holding Company Act of 1956 (12 U.S.C. 1841(a)); except that the Board may, upon application of such foreign bank or other company, extend the 2-year period for not more than one year at a time, if, in its judgment, such an extension would not be detrimental to the public interest, but no such extensions shall exceed 3 years in the aggregate.
