The matter may nevertheless be further investigated at any time if circumstances so warrant.(c) In matters in which a recipient of a preservation demand, an access letter, or Commission compulsory process has not been notified that an investigation has been closed or otherwise concluded, after a period of twelve months following the last written communication from the Commission staff to the recipient or the recipient's counsel, the recipient is relieved of any obligation to continue preserving information, documentary material, or evidence, for purposes of responding to the Commission's process or the staff's access letter. The "written communication" may be in the form of a letter, an email, or a facsimile.(d) The Commission has delegated to the Directors of the Bureaus of Competition and Consumer Protection, their Deputy Directors, the Assistant Directors of the Bureau of Competition, the Associate Directors of the Bureau of Consumer Protection, and the Regional Directors, without power of redelegation, limited authority to close investigations.77 FR 59309, Sept. 27, 2012
