Which act governs the treatment of a consumer's non-public information?

The treatment of a consumer's non-public information is primarily governed by Regulation P. This regulation is part of the federal privacy regulations implemented by the Gramm-Leach-Bliley Act, which seeks to protect the privacy of consumers' financial information. Regulation P specifically outlines how financial institutions must handle non-public personal information, including requirements for privacy notices, limitations on sharing information with non-affiliated third parties, and conditions under which consumers can opt-out of such information sharing.

By understanding Regulation P, institutions and professionals can ensure they comply with the necessary standards for safeguarding consumer data, ultimately fostering trust and maintaining the confidentiality of sensitive information. The other options listed relate to different areas of regulatory frameworks but do not primarily address the treatment of a consumer's non-public information like Regulation P does.
