17 CFR § 11.3 - Confidentiality of investigations.
All information and documents obtained during the course of an investigation, whether or not obtained pursuant to subpoena, and all investigative proceedings shall be treated as non-public by the Commission and its staff except to the extent that (a) the Commission directs or authorizes the public disclosure of the investigation; (b) the information or documents are made a matter of public record during the course of an adjudicatory proceeding; or (c) disclosure is required by the Freedom of Information Act, 5 U.S.C. 552, and the rules adopted by the Commission thereunder, 17 CFR part 145. Procedures by which persons submitting information to the Commission during the course of an investigation may specifically seek confidential treatment of information for purposes of Freedom of Information Act disclosure are set forth in 17 CFR 145.9. A request for confidential treatment of information for purposes of the Freedom of Information Act shall not, however, prevent disclosure for law enforcement purposes or when disclosure is otherwise found appropriate in the public interest and permitted by law.
