Series 66: Procedural Deadlines — The Numbers They Always Test
5 deadlines · Shortest to longest
Brochure Rule (USA)
State-registered IAs must deliver the brochure (Form ADV Part 2) 48 hours prior to signing the advisory contract. Exception: deliver at signing if the client gets 5 business days to cancel penalty-free.
48 Hours
Request Hearing (Summary Order)
If the Administrator issues a summary order (cease & desist without a prior hearing), you have 15 days to submit a written request for a hearing. Miss it and the order becomes final.
15 Days
Rescission Offer
If you offer to buy back a security sold in violation of the USA (rescission offer), the client has 30 days to accept or reject. No response = no right to sue for that transaction.
30 Days
Appeal a Final Order
Disagree with a Final Order from the Administrator? File an appeal with the appropriate court within 60 days. Strict deadline — miss it and you can't challenge the order.
60 Days
Pay-to-Play Ban
If an IA makes a political contribution to an elected official who can influence advisory contract awards, the IA is banned from compensation from that government entity for 2 years.
2 Years
The ascending sequence: 48 hours → 15 days → 30 days → 60 days → 2 years. Each step up is roughly 2× the previous. Brochure (smallest) → Ban (longest).
Series 66: Registration & Operations Deadlines
4 deadlines · When things take effect
Effective Date of Registration
Registration becomes effective at noon on the 30th day after filing, unless the Administrator acts sooner. Same timeline applies to withdrawal (Form U5 / Form ADV-W).
30 Days
Material Changes to U4 / ADV
Changes to name, address, or felony disclosures must be updated "promptly" — generally interpreted as within 30 days.
Promptly
Registration Expiration
All state registrations (agents, IARs, IAs, BDs) expire December 31 each year. Fees are not prorated — full fee regardless of when you register.
Dec 31
Annual Brochure Delivery
IAs must deliver an updated brochure (or summary of material changes) to existing clients within 120 days of fiscal year-end. Separate from the 48-hour new-client rule.
120 Days
Common Exam Trap
There are two brochure deadlines: the 48-hour rule is for new clients (before signing the contract). The 120-day rule is for existing clients (annual update after fiscal year-end). The exam tests whether you know which applies to which situation.
Series 66: Statutes of Limitation — Civil, Criminal & Custody
3 statutes · When can they come after you?
Criminal Statute
The Administrator can bring criminal action for a securities violation up to 5 years after the alleged violation.
5 Years
Civil Liability (Statute of Limitations)
A client can sue you. The deadline is the sooner of: 3 years from the date of the sale (or advice) — or — 2 years from the date of discovery of the violation. Whichever comes first.
3y / 2y
Inadvertent Custody
If an IA inadvertently receives client funds/checks, they must return them within 3 business days to avoid triggering custody reporting requirements.
3 Biz Days
Common Exam Trap
Civil liability is the sooner of 3 years from sale OR 2 years from discovery — not the later. The exam will give you both dates and ask you to pick the controlling one. Always pick whichever deadline arrives first.
Series 66: Record Retention Pyramid — BD (3/6/Life) vs. IA (5/Life)
4 tiers · Know which entity uses which rule
BD = 3 / 6 / Life
IA = 5 / Life (first 2 yrs in principal office)
Lifetime
Both BD & IA — Articles of incorporation, partnership articles, stock certificates, minute books. Kept for life of firm + 3 years after closing.
6 Years
Broker-Dealers only (Principal Records) — Blotters, general ledgers, customer ledgers, stock records, account records.
5 Years
Investment Advisers (Standard) — Nearly everything: journals, ledgers, confirmations, order tickets, bills, communications. First 2 years must be in the principal office.
3 Years
Broker-Dealers (Standard) — Advertising, confirmations, order tickets, U4/U5 forms, fingerprints, communications.
IAs don't have a 6-year tier — they jump straight from 5 years to Lifetime. BDs have both 3 and 6. The exam tests whether you confuse the BD and IA rules.
The "Closed Doors" Trap
Going out of business does NOT stop the retention clock. You must preserve records for the remainder of the required retention period even after closing. Example: If a BD generated a trade confirmation 1 year ago (3-year record) and closes today, they must keep that confirmation for 2 more years. You cannot shred on your way out.
