Broker-Dealer Operations

Review account workflow, cashiering, custody, reporting, margin, settlement, confirmations, financial controls, and records tested on Series 99.

The first Series 99 chapter carries most of the exam because the Operations Professional role is built around workflow accuracy and control. FINRA expects candidates to understand what happens to a customer account after it is opened, how funds and securities move, how trades and corrections are processed, how statements and confirmations are produced, and how the firm’s books, records, and financial controls support that activity.

The best way to study this chapter is as a connected operating chain. Start with account opening and maintenance, then move to money movement, custody, and trade processing. Finish with statements, financial reporting, and records so the control framework remains tied to the customer workflow it is supposed to support.
