(4)Nonpublic personal information
(A)The term “nonpublic personal information” means personally identifiable financial information—
(i)provided by a consumer to a financial institution;
(ii)resulting from any transaction with the consumer or any service performed for the consumer; or
(iii)otherwise obtained by the financial institution.
(B)Such term does not include publicly available information, as such term is defined by the regulations prescribed under section 6804 of this title.
(C)Notwithstanding subparagraph (B), such term—
(i)shall include any list, description, or other grouping of consumers (and publicly available information pertaining to them) that is derived using any nonpublic personal information other than publicly available information; but
(ii)shall not include any list, description, or other grouping of consumers (and publicly available information pertaining to them) that is derived without using any nonpublic personal information.(GLBA, 15 U.S.C. § 6809(4)(B))
PIFI is defined in Securities and Exchange Commission (SEC), Final Rule: Privacy of Consumer Financial Information (Regulation S-P) 17 CFR Part 248 (2000). Available at: https://www.sec.gov/rules/final/34-42974.htm
Both the GLBA and the regulations define NPI[5] in terms of PIFI.
The GLBA does not define PIFI but the FTC regulations define the term to mean any information:
(i) A consumer provides to you [the financial institution] to obtain a financial product or service from you;
(ii) About a consumer resulting from any transaction involving a financial product or service between you and a consumer; or
(iii) You otherwise obtain about a consumer in connection with providing a financial product or service to that consumer.
