Introduction

Welcome to Discrepancies, Complaints, and Arbitration: the back-end of the trade lifecycle that handles errors, customer grievances, and formal dispute resolution. Unit 11 covered how trades get priced (quotes and best execution). Unit 12 covered how they clear and settle. Unit 13 covers what happens when something goes wrong.

Exam Weight: Part of 10% (5 questions across Chapter 4)

What You'll Learn

In this unit, you'll cover:

• Trade Errors and As-Of Pricing: the difference between firm-caused and customer-caused errors; cancel-and-rebill supervisory approval under FINRA Rule 4515; as-of pricing for mutual-fund corrections (firm-caused errors use the originally-intended Net Asset Value (NAV) date; customer-caused errors use the next NAV)
• Customer Complaints and Rule 4513: the definition of a "complaint" (written grievances only); the Office of Supervisory Jurisdiction (OSJ) file and 4-year retention; proper escalation through a principal; why private settlements are prohibited
• Reporting Obligations Under Rule 4530: the 30-calendar-day reporting clock for specified events; theft and misappropriation allegations; internal-investigation conclusions; the dollar thresholds ($15,000 associated person / $25,000 firm) for settlements and awards; the quarterly statistical complaint report due by the 15th calendar day after quarter-end
• Dispute Resolution Methods: the 12000 Series (customer disputes), the 13000 Series (industry disputes), and the 14000 Series (mediation); the customer's right to compel arbitration under Rule 12200; the 6-year eligibility limit under Rule 12206; why arbitration awards are generally final and non-appealable
• Form U4 and U5 Disclosure: the $5,000 threshold for customer-complaint disclosure on Form U4; 30-day amendment obligations; Form U5 filing on termination; BrokerCheck as the public-facing window into Central Registration Depository (CRD) disclosures
• Investigations and Sanctions (8000 Series): Rule 8210 information and testimony requests (non-cooperation is a bar-level offense); the sanction menu under Rule 8310; statutory disqualification under Securities Exchange Act (SEA) Section 3(a)(39) and the MC-400 eligibility pathway

Why This Matters

Function 4.3 tests the back-office machinery that protects customers and enforces sales-practice standards. A Series 6 rep does not personally run arbitration panels or file disclosure reports, but the exam expects the rep to recognize:

• When a customer grievance is a "complaint" under Rule 4513 (written) versus a verbal frustration (not reportable under 4513)
• When a firm must file a 4530 report (30 calendar days) and when it must amend Form U4 (30 days) and how disclosure on one can satisfy the other
• What an arbitration award looks like (final, binding, very limited appeal) versus a mediated settlement (voluntary, non-binding until signed)
• Why failing to respond to an 8210 information request typically produces a bar that is more severe than the underlying allegation
• Which events on a rep's record become publicly searchable on BrokerCheck and which stay internal to the firm

The sections below walk the operational chain from the moment of error through the enforcement endgame:

• First the trade error that must be corrected before anything else matters
• Then the customer complaint that memorializes a grievance the rep did not fix quietly
• Then the firm's reporting obligations to FINRA under Rule 4530
• Then the formal dispute-resolution forums (arbitration, mediation, and litigation)
• Then the rep-level disclosures on Forms U4 and U5 and their public display on BrokerCheck
• Finally the FINRA enforcement machinery of investigations, sanctions, and statutory disqualification

Let's start with trade errors, which are the earliest point in the chain where things can go wrong.
