3. DECLARATION Timetable

Upon receipt of a declaration submitted pursuant to 31 C.F.R. § 800.403, the Staff Chairperson will promptly inspect the declaration for completeness.  Upon determining that the declaration meets all requirements set forth at 31 C.F.R. § 800.404 and, therefore, is complete, the Staff Chairperson will accept the declaration and circulate the declaration to all CFIUS agencies.  Upon accepting a declaration, the Staff Chairperson will promptly notify the parties in writing of the date that the assessment period started.  This assessment period ends no later than the 30th day after it has commenced, or if the 30th day is not a business day, no later than the next business day after the 30th day.  Similarly, the Staff Chairperson or other Treasury Department official will advise the parties in writing if CFIUS requires further information or action by the parties.

Throughout declaration review, parties must respond to requests for information within two business days of the request or within a longer time frame if the parties so request in writing and the Staff Chairperson grants that request in writing.


Each party to a transaction filing a declaration must provide a certification of the information contained in the declaration consistent with 31 C.F.R. § 800.204.  The certification must be signed by the chief executive officer or other duly authorized designee of each party to a transaction filing a declaration.

If the Committee notifies the parties to a transaction that have submitted a declaration pursuant to 31 C.F.R. § 800.401 or 31 C.F.R. § 800.402 that the Committee intends to conclude all action under section 721 with respect to that transaction, each party that has submitted additional information subsequent to the original declaration must file a certification as described in 31 C.F.R. § 800.204.

The requirements for the certifications, including the contents and the person(s) who may sign the certification, are set forth at 31 C.F.R. § 800.204.  Following are sample certifications:
