The following is from Post 85:

To assist in making this determination, Exon-Florio provides for the President or his designee to receive written notice of an acquisition, merger or takeover of a U.S. corporation by a foreign entity. Once CFIUS has received a complete notification, it begins a thorough review of the notified transaction. In some cases, it is necessary to undertake an extended review or "investigation." An investigation, if necessary, must begin no later than 30 days after receipt of a notice. Any investigation is required to end within 45 days.
Information provided by companies contemplating a transaction subject to Exon-Florio is held confidential and is not made public, except in the case of an administrative or judicial action or proceeding. Nothing in section 721 shall be construed to prevent disclosure to either House of Congress or to any duly authorized committee or subcommittee of the Congress.
This order also provides for CFIUS to submit a report and recommendation to the President at the conclusion of an investigation.
