No single U.S. federal statute or regulation defines Confidential Information in the competition context. Instead, various federal statutes, rules, and policies require that the DOJ treat certain information it obtains as confidential and protect it from public disclosure. Several statutes require the DOJ and FTC to treat as confidential certain information obtained in the course of an investigation. The HSR Act prohibits FTC and DOJ from disclosing information obtained pursuant to the act, including the fact that the parties filed notice of a proposed transaction and confidential business information provided in a filing or in response to a document or information request.  Other federal laws also require the FTC and DOJ to treat specific types of information as confidential, without regard to the manner in which the information is obtained. For example, laws governing privacy, national security information, and trade secrets require that the Agencies treat certain information as confidential.

DOJ and FTC have defined “confidential information” in the Model Waiver and in the accompanying Frequently Asked Questions (“FAQ”) as “written, electronic, and oral information including, but not limited to, Entity’s documents, data, statements, interrogatory responses, transcripts, oral communications, testimony, and remedial proposals, either in original form, as copies, or as incorporated or reflected in FTC or DOJ internal analyses, that the Confidentiality Rules would prohibit from disclosure.”  See https://www.justice.gov/atr/file/705866/download
