An operations professional at a mid-sized broker-dealer felt secure. Her team had just implemented a new cloud storage system, and she assumed "digital" meant "compliant." During a FINRA cycle exam, auditors flagged a major deficiency: trade blotters from three years prior were stored in a standard, editable format. This violated SEC Rule 17a-4's strict "non-rewritable, non-erasable" requirement, resulting in a six-figure fine and a public censure. The firm stored the right records, but they failed to preserve their integrity.
SEC Rules 17a-3, 17a-4, and 17a-5 are the bedrock of broker-dealer compliance. Rule 17a-3 specifies what records to create (e.g., blotters, ledgers). Rule 17a-4 dictates how and for how long to preserve them (e.g., WORM format, 6-year retention). Rule 17a-5 governs when to file financial reports, like the FOCUS Report.

What Records Must Broker-Dealers Keep Under SEC Rule 17a-3?
SEC Rule 17a-3 is the foundational list of every book and record a broker-dealer must create and keep current. Think of it as the mandatory evidence of a firm's business activities. Without these specific records, regulators have no way to reconstruct trades, audit financial health, or protect customer assets.
Core Record Categories
While the full list is extensive, the Series 99 exam centers on your understanding of the main categories and their purpose.

- Blotters: These are the firm's daily diaries. They are records of original entry showing all purchases and sales of securities, cash receipts and disbursements, and securities received and delivered. They must be prepared no later than the following business day (T+1).
- Ledgers: These are the master accounting records reflecting all assets, liabilities, income, expense, and capital accounts. This includes the crucial securities record, or "stock record," which shows all long and short positions for each security.
- Customer Account Records: For each customer, the firm must maintain a record detailing their name, address, tax ID, and investment objectives.
- Order Tickets (Memoranda of Brokerage Orders): Every single order must have a corresponding ticket that includes the customer's account identifier, the terms of the order (buy/sell, security, quantity), the time of entry, the price of execution, and the identity of the associated person who handled the order.
The Order Ticket Test
The details on an order ticket are a frequent source of exam questions. The examiner wants to know if you can distinguish essential audit trail information from irrelevant data. An accurate ticket is the first step in the entire compliance chain. If the ticket is wrong, everything that follows, from the blotter entry to the FOCUS report, will also be wrong. Try VoraPrep's free Series 99 practice questions to see how these details are tested.
How Must Firms Preserve Records Under SEC Rule 17a-4?
Creating a record is only the first step. SEC Rule 17a-4 dictates how long those records must be kept and, critically, in what format. This is where many firms, and exam candidates, make costly mistakes. The rule's purpose is to ensure records are authentic, accessible, and tamper-proof for the entire retention period.
The Three Tiers of Retention Periods
Not all records are treated equally. You must know the three main timeframes.
- Life of the Enterprise: Foundational corporate documents must be preserved for the life of the firm and any successor enterprise. This includes articles of incorporation, partnership agreements, and board meeting minute books.
- Six Years: This is the standard for core transactional and financial records. The key records here are blotters, general ledgers, customer ledgers, and the stock record.
- Three Years: This is the catch-all for most other records, including order tickets, trade confirmations, trial balances, and all communications (including emails and instant messages).
> ⚠️ Exam trap: The "Readily Accessible" Clock > > For both the six-year and three-year categories, the records must be kept in a "readily accessible place" for the first two years. This is a classic exam trap. A question might describe a 4-year-old blotter stored in a remote warehouse that takes a week to retrieve. Is this a violation? No, because it's past the 2-year readily accessible window. But if it were a 1-year-old blotter, it would be a clear violation. "Readily accessible" means producible on demand, typically the same day.
The WORM Format and the "Undertaking"
For electronic records, accessibility isn't enough. They must be preserved in a format that ensures they cannot be altered or destroyed.
Rule 17a-4(f) requires electronic storage media to:
- Preserve records exclusively in a non-rewritable, non-erasable format. This is known as WORM ("Write-Once, Read-Many").
- Automatically verify the quality and accuracy of the recording process.
- Maintain a duplicate copy at a separate location.
Before using electronic storage, the firm must also file an undertaking with its Designated Examining Authority (DEA), like FINRA. This is a formal agreement to promptly provide regulators with legible, true, and complete copies of any requested records. It's more than a simple notification; it's a binding promise.
What Are the Reporting Deadlines Under SEC Rule 17a-5?
SEC Rule 17a-5 requires broker-dealers to file regular financial reports with regulators. The central report is the Financial and Operational Combined Uniform Single (FOCUS) Report, which gives the SEC and FINRA a detailed look into the firm's financial stability.
Decoding the FOCUS Report (Part II vs. IIA)
The FOCUS report comes in two primary flavors that you'll need to distinguish.
- FOCUS Report Part II: Filed by firms that clear transactions or carry customer accounts. These firms have higher risk profiles and must file monthly, within 17 business days after the end of the month.
- FOCUS Report Part IIA: Filed by firms that do not clear or carry customer accounts (e.g., introducing brokers). These firms generally file quarterly, also within 17 business days after the end of the quarter.
Key Deadlines: 17 Business Days vs. 60 Calendar Days
Memorizing the deadlines is essential.

- 17 Business Days: For monthly (Part II) and quarterly (Part IIA) FOCUS reports.
- 60 Calendar Days: For the firm's annual audited financial statements. This report must be certified by an independent public accountant and is due within 60 days of the firm's fiscal year-end.
Notice the difference between "business" and "calendar" days. The exam will test this distinction.
The Exemption Report and the Accountant's Review
Firms that claim an exemption from the Customer Protection Rule (SEC Rule 15c3-3) must file an annual Exemption Report. This report asserts that the firm has met the conditions for its exemption throughout the year. An independent public accountant must then perform a review of this report and issue their own findings. The exam may try to trick you with other terms like "audit" or "attestation," but for the Exemption Report, the correct term is review.
How Does T+1 Settlement Impact These Rules on the 2026 Exam?
The industry's move to a T+1 settlement cycle in 2024 is a monumental shift and a major focus for the 2026 Series 99 exam. Faster settlement compresses every operational process, placing immense pressure on the accuracy and timeliness of the books and records we've just discussed.
An examiner wants to see that you understand these second-order effects.
- Impact on 17a-3: Blotters must be prepared by the next business day. In a T+1 world, there is zero room for error in capturing trade details on trade date. A single incorrect order ticket could lead to a trade fail, which must be accurately recorded.
- Impact on 17a-4: Records of trade fails, allocations, and affirmations now occur on a compressed timeline. These records must be created and preserved flawlessly under the new speed.
- Impact on 17a-5: The data feeding into the FOCUS report, especially calculations related to fails to deliver and fails to receive, is generated much faster. An operational breakdown in T+1 settlement will immediately impact the accuracy of the firm's financial reporting.
> 💡 Worked example: The T+1 Ripple Effect > > A firm executes a customer trade on Monday. Under T+1, it must settle on Tuesday. However, due to a data entry error on the order ticket (a 17a-3 violation), the trade fails to settle on Tuesday. > > Question: What are the immediate compliance implications? > > A. The firm has until Wednesday to fix the record. > B. The firm must create a record of the "fail to deliver" on its blotter for Tuesday and preserve it for six years. > C. The firm can ignore the fail for reporting purposes until it is resolved. > D. The firm only needs to notify the customer of the delay. > > Analysis: The most tempting wrong answer is A, suggesting there's a grace period. There isn't. The correct answer is B. The T+1 failure creates a new event that must be recorded immediately on the firm's books (blotter) under Rule 17a-3. That new record of the fail must then be preserved for six years under Rule 17a-4. Furthermore, this outstanding fail will impact the firm's Net Capital computation, which is calculated for the FOCUS report under Rule 17a-5. The single ticket error has now triggered compliance requirements across all three rules.
What Other Major Topics Are on the Series 99?
While books and records are a critical component, they are not the entire exam. To pass, you must also have a firm grasp of several other key operational areas. A complete study plan, like the one VoraPrep provides, will ensure you cover these topics in depth.
- SEC Rule 15c3-3 (The Customer Protection Rule): Governs the possession or control of customer securities and the reserve formula for customer cash.
- SEC Rule 15c3-1 (The Net Capital Rule): Ensures firms maintain sufficient liquid capital to meet their obligations.
- Clearing and Settlement: The functions of the DTCC, NSCC, and the Continuous Net Settlement (CNS) system.
- Anti-Money Laundering (AML): Customer Identification Programs (CIP), Suspicious Activity Reports (SARs), and Currency Transaction Reports (CTRs).
- Trade and Account Transfers: Procedures for ACATS (Automated Customer Account Transfer Service).

Frequently asked questions
What is the difference between SEC Rule 17a-3 and 17a-4 for the Series 99 exam?
SEC Rule 17a-3 lists what records a broker-dealer must create (e.g., blotters, order tickets). SEC Rule 17a-4 dictates how and for how long those records must be preserved. For example, 17a-3 requires an order ticket, and 17a-4 requires you to keep it for three years in an accessible format.How has T+1 settlement changed the Series 99 exam for 2026?
The move to T+1 settlement has made operational efficiency critical, and the 2026 exam reflects this. You will be tested on the downstream effects of faster settlement, including the immediate need for accurate blotters (17a-3), the recording of trade fails, and the impact on financial calculations for the FOCUS report (17a-5).What are the main FOCUS Report filing deadlines I need to know?
You must know two key deadlines. Monthly (for clearing firms) and quarterly (for non-clearing firms) FOCUS reports are due within 17 business days of the period's end. The annual audited financial report is due within 60 calendar days of the firm's fiscal year-end.Besides books and records, what other rules are important for the Series 99?
Beyond Rules 17a-3, 17a-4, and 17a-5, the Series 99 exam heavily tests the SEC's Customer Protection Rule (15c3-3) and Net Capital Rule (15c3-1). You must also understand clearing agency functions (DTCC/NSCC), account transfers (ACATS), and anti-money laundering (AML) regulations.---
