Custody is broadly defined under SEC Rule 206(4)-2 and NASAA rules to include any arrangement where an adviser holds client funds or has authority to access them (such as fee deduction authority or full power of attorney). If an adviser maintains custody, assets must be kept at a qualified custodian (bank or broker-dealer) who sends quarterly account statements directly to clients.
Advisers with custody must undergo an annual surprise examination by an independent public accountant to verify client assets. The accountant files Form ADV-E with the SEC or state Administrator within 120 days. A safe harbor protects advisers who forward third-party checks or return inadvertent receipts within 3 business days.
Advisers must adopt a written Code of Ethics under Rule 204A-1. Access persons must report personal securities holdings within 10 days of joining the firm and annually thereafter, and file quarterly transaction reports within 30 days of quarter-end. Pre-clearance is required for IPOs and private placements.
