Free and printable — use your browser's print function for a clean copy. Updated 2026-07-05.

Types of Communications

  • Retail Communication (formerly "advertising")
  • Any written/electronic communication to 25+ retail investors within 30 days
  • Must be approved by a principal BEFORE first use (pre-approval)
  • Must be filed with FINRA within 10 business days of first use
  • New member firms: must pre-file with FINRA for first year
  • Institutional Communication
  • Communication to institutional investors only
  • Does NOT require pre-approval (but must have supervisory procedures)
  • Must be reviewed by principal (but can be after use)
  • Institutional = entities with 50M+ in assets, registered investment advisers, B/Ds
  • Correspondence
  • Written communication to 25 or fewer retail investors within 30 days
  • Does NOT require pre-approval
  • Must be subject to firm supervision/review procedures

Reporting Thresholds

  • SAR (Suspicious Activity Report)
  • $5,000+ in suspicious activity through an account
  • $2,000+ if involving an employee
  • Filed with FinCEN (not the customer — do NOT notify the customer!)
  • Must file within 30 days of detection
  • CTR (Currency Transaction Report)
  • Cash transactions exceeding $10,000 in a single day
  • STRUCTURING: deliberately breaking up transactions to avoid reporting = ILLEGAL
  • Filed with FinCEN
  • Large Trader Reporting (Rule 13H)
  • 2 million shares or $20 million in a single day
  • OR 20 million shares or $200 million in a calendar month
  • Must file Form 13H with the SEC

Customer Complaints

  • Written complaints must be kept for 4 YEARS
  • Must be reported to FINRA
  • Electronic complaints (email) count as written
  • Must have procedures for handling complaints

Books & Records

  • Trade blotters, customer account records, communications: 6 YEARS (first 2 in easily accessible location)
  • Customer complaints: 4 YEARS
  • Partnership articles: 3 YEARS after dissolution
  • Firms must maintain and preserve in compliance with SEC Rule 17a-4

Key facts to memorize

  • Retail communication: 25+ investors, pre-approval required, file with FINRA within 10 business days
  • Institutional: 50M+ assets, no pre-approval, review after use OK
  • Correspondence: 25 or fewer, no pre-approval required
  • SAR: $5K (account), $2K (employee) — never tell customer
  • CTR: $10K+ cash in one day
  • Structuring = illegal
  • Written complaints: keep 4 years
  • General books/records: 6 years

Mnemonics that stick

  • "25+ retail = Retail communication (needs pre-approval); 25 or fewer = Correspondence"
  • "SAR = Suspicious, $5K account / $2K employee — NEVER tell the customer"
  • "CTR = Cash over $10K — Currency Transaction Report"
  • "Structuring = Sneakily splitting to stay under $10K = ILLEGAL"
  • "Written complaints = 4 years; General records = 6 years"
  • "Retail = 10 business days to file with FINRA after first use"

Exam traps

  • You must NEVER notify the customer that a SAR has been filed — this is a serious violation
  • Retail communications need principal pre-approval BEFORE first use
  • Correspondence (25 or fewer) does NOT require pre-approval
  • Institutional investors = 50M+ assets (not just any business)
  • Structuring cash transactions to avoid CTR reporting is ILLEGAL
  • Customer complaints kept 4 years, but most other records kept 6 years
  • SARs are filed with FinCEN, not FINRA or SEC
