Worked Practitioner Scenario

Practitioner Application: Regulation S-P: Customer Privacy and Safeguarding Information

A new client calls your firm, concerned they haven't received a privacy notice. They recall providing sensitive financial details when opening their account and are unsure how their 'nonpublic personal information' (NPI) is being used or if they can opt out of certain disclosures. Meanwhile, an internal audit reveals that some customer data is being stored on unencrypted local drives, contrary to firm policy. As an operations professional, you must ensure strict adherence to federal privacy regulations.

  1. Financial institutions, including broker-dealers, are subject to Regulation S-P (17 CFR §248.1 et seq.), which mandates the protection of 'nonpublic personal information' (NPI) of their customers. This rule stems from the Gramm-Leach-Bliley Act (GLBA) and requires firms to develop and maintain safeguards for customer NPI, provide privacy notices, and allow customers to opt out of certain information sharing.
  2. What is 'Nonpublic Personal Information' (NPI)? NPI includes any personally identifiable financial information that a financial institution collects about an individual, which is not publicly available. Examples include account numbers, social security numbers, income and asset information, transaction history, and information derived from such data. Importantly, NPI also includes 'personally identifiable information' (PII) if that PII is also financial in nature.
1. Privacy Notices: Firms must provide clear and conspicuous notices to customers regarding their privacy policies and practices. Initial Privacy Notice: Must be provided at the time a customer relationship is established. This notice explains the types of NPI collected, categories of parties with whom it may be shared, and the customer's right to opt out. Annual Privacy Notice: Must be provided to customers at least once a year during the continuation of the customer relationship. This notice reiterates the firm's privacy policy and the customer's opt-out rights. * Revised Privacy Notice: Required if the firm's privacy policy materially changes, for example, if the firm begins sharing NPI with new categories of nonaffiliated third parties not previously disclosed.
