Worked Practitioner Scenario

Practitioner Application: Opening Customer Accounts: FINRA Rules and Key Ownership Structures

A prospective client, Ms. Elena Rodriguez, has approached you to open a new brokerage account. She is a successful entrepreneur, newly married, and wants to set up an account that can be easily passed to her spouse upon her death, but she also wants full control during her lifetime. She's also inquiring about opening a separate account for her 12-year-old niece to save for college. What are the critical regulatory steps you must follow for both accounts, and what specific information is required to ensure compliance and proper account structuring?

  1. Opening a new customer account involves a rigorous process mandated by FINRA to protect both the customer and the broker-dealer, ensuring suitability and preventing illicit activities. Key rules governing this process include FINRA Rule 2090 (Know Your Customer) and FINRA Rule 4512 (Customer Account Information).
  2. Required Information for Account Opening (FINRA Rule 4512): Before or at the time of account opening, broker-dealers must gather specific information to ensure they "know their customer" and can make suitable recommendations. While some information is legally required, other details are crucial for suitability analysis.
Account Approval and Verification: 1. Principal Approval: All new accounts must be approved by a registered principal of the broker-dealer. This approval signifies that the firm has reviewed the information and deems the account suitable and compliant. This approval must occur promptly after the completion of the customer's initial transaction in the account, but ideally before. 2. Customer Account Information Verification: Within 30 days of account opening, the broker-dealer must send a copy of the account information to the customer for verification. Subsequently, firms must send updated account information to customers at least once every 36 months for verification. 3. Account Name/Number: An account name and number must be assigned. 4. Date of Birth and Tax ID: Essential for compliance and IRS reporting.
Exam Watchouts & Statutory Boundaries

Common FINRA Series 7 Distractors on FINRA Rule 2090

  • 1Principal Approval Timing: A common trap is suggesting that principal approval is optional or can be delayed indefinitely. Remember, it's mandatory and must be promptly after the first transaction, but ideally before.
  • 2"Kiddie Tax" Confusion: While assets in UGMA/UTMA accounts are taxed at the minor's rate, unearned income above a specific threshold is taxed at the parent's marginal rate, which is often higher. This "kiddie tax" rule is a common point of confusion.
  • 3Joint Account Beneficiaries: Remember the difference between JTWROS (survivor gets assets) and TIC (estate gets assets).
  • 4Required Information vs. Desired Information: The exam might list information that is useful for suitability but not legally required by FINRA Rule 4512 for opening. Focus on the statutory requirements.
  • 5Principal Approval is Mandatory: All new accounts require prompt principal approval.
