Topic: Function 1 - Financial Reporting
A broker-dealer files its FOCUS Report each month through FINRA’s electronic filing system. The FINOP learns that the filing is submitted by an outside accounting consultant using a shared “FINOP” username/password known by multiple people. The firm does not retain the system-generated filing confirmation or a screenshot/PDF of the submitted report; the only “proof” is an email from the consultant saying it was filed.
Which is the primary operational control concern/red flag in this process?
Best answer: A
Explanation: Electronic regulatory submissions require basic controls over who can file, how changes are authorized, and how the firm proves the filing occurred. Shared credentials defeat accountability, and failing to retain the system confirmation and a copy of what was transmitted creates a record-integrity gap. A FINOP should ensure controlled access, review/approval, and durable retention of filing evidence.
Topic: Function 4 - Net Capital
In the context of SEC Net Capital Rule 15c3-1 operational charges, which statement best explains why aged fails to deliver/receive can result in net capital deductions (often described as “fail charges”) and increased supervisory attention?
Best answer: B
Explanation: Aged fails indicate that securities or cash have not been exchanged as expected, creating an unsecured exposure and operational uncertainty. As fails age, they can require operational deductions (fail charges) or be treated as non-allowable items that reduce net capital. Regulators also view persistent aged fails as a red flag for weak settlement processing, reconciliations, and supervisory controls.
Topic: Function 4 - Net Capital
A FINOP is reviewing a broker-dealer’s month-end liabilities to determine Aggregate Indebtedness (AI) under SEC Rule 15c3-1. The firm’s balance sheet includes accounts payable to vendors, accrued payroll and payroll taxes, a repurchase agreement (repo) payable, and customer free credit balances.
Which statement about what is included in AI is INCORRECT?
Best answer: C
Explanation: Aggregate Indebtedness generally reflects a broker-dealer’s unsecured liabilities and similar obligations. Common contributors include accounts payable, accrued expenses, and securities financing obligations such as repos. Customer free credit balances are also firm liabilities, so treating them as excluded is incorrect.
Topic: Function 1 - Financial Reporting
On April 15, the broker-dealer’s independent public accountant notifies the FINOP that it is resigning immediately and will not stand for reappointment, citing unresolved concerns about the firm’s revenue recognition documentation and access to supporting records. The audit is still in progress.
Which action by the FINOP best aligns with the control objective of regulatory notifications related to auditor changes?
Best answer: D
Explanation: A change in an independent public accountant—especially a resignation tied to documentation and access concerns—is a reportable event that should be escalated promptly to regulators. The control objective is to provide timely transparency into potential financial reporting or audit-scope issues so regulators can assess the firm’s financial reporting integrity and customer protection risks. The FINOP should also ensure required supporting correspondence is obtained and retained with the notification.
Topic: Function 3 - Customer Protection
Delta Securities is a fully disclosed introducing broker that clears and carries customer accounts through Omega Clearing under a written clearing agreement. Delta has been treating itself as exempt from SEC Customer Protection Rule 15c3-3 based on its introducing relationship.
During a review, the FINOP learns that (1) some customers wire funds into Delta’s operating account before Delta transmits them to Omega, and (2) registered reps occasionally accept physical customer securities certificates at a branch and send them to Omega the next day.
Which FINOP action best aligns with durable exemption-analysis standards under Rule 15c3-3?
Best answer: A
Explanation: Customer Protection Rule exemptions for introducing firms are driven by the clearing/carrying allocation and, critically, whether the introducing firm actually receives or holds customer funds or securities. Here, Delta’s receipt of customer wires and physical certificates indicates it is handling customer assets inconsistent with an “introducing-only” exemption posture. The FINOP should reassess the exemption immediately and either change processes so assets go directly to the carrying firm or implement full 15c3-3 compliance as applicable.
Topic: Function 3 - Customer Protection
A carrying broker-dealer maintains a PAB reserve bank account under SEC Customer Protection Rule 15c3-3. The firm’s written election is to compute the PAB reserve requirement monthly.
Exhibit: PAB reserve control log (USD)
Election (PAB computation): Monthly
Last PAB computation date: January 31
PAB requirement per computation: $5,000,000
Balance in PAB reserve bank account on Jan 31 (after deposit): $5,000,000
Cash movement on February 10: Withdrawal of $800,000 (no new PAB computation performed)
Next scheduled PAB computation date: February 28
Which interpretation is supported by the exhibit and baseline Rule 15c3-3 concepts about computation frequency and reserve bank account funding?
Best answer: B
Explanation: PAB reserve computation frequency drives how often the firm must size and adjust the PAB reserve bank account based on a documented computation. With a monthly election, the last supported requirement is the January 31 computation, which required maintaining $5,000,000. An $800,000 mid-month withdrawal with no new computation is not supported by the firm’s documented reserve requirement.
Topic: Function 1 - Financial Reporting
A broker-dealer has completed its fiscal year-end close and obtained an independent auditor’s report. The FINOP is confirming the firm’s regulatory notification obligations under Exchange Act Rule 17a-5.
Which option best matches the required method and handling of the firm’s annual audited financial report?
Best answer: C
Explanation: Under Exchange Act Rule 17a-5, the annual audited financial report is a formal regulatory filing, not merely a record to retain. It is submitted to the SEC and the firm’s designated examining authority and is executed by appropriate firm signers, including the FINOP.
Topic: Function 1 - Financial Reporting
A broker-dealer introduces all customer accounts to a clearing firm, does not hold customer funds or securities, and claims an exemption from the SEC Customer Protection Rule (SEC Rule 15c3-3). Under Exchange Act Rule 17a-5 annual financial reporting, which filing/report is intended to describe the exemption relied upon and assert that the firm met the exemption conditions during the most recent fiscal year?
Best answer: D
Explanation: Under Exchange Act Rule 17a-5, broker-dealers file an annual audited report package. If the firm claims an exemption from SEC Rule 15c3-3, it must include an exemption report describing the specific exemption conditions and asserting they were met for the fiscal year. That function is distinct from both the compliance report and routine FOCUS reporting.
Topic: Function 4 - Net Capital
A broker-dealer computes net capital under SEC Net Capital Rule 15c3-1. For internal monitoring, the FINOP applies an additional “undue concentration” deduction when any single issuer’s proprietary equity position exceeds 10% of tentative net capital (TNC), because large positions may be difficult to liquidate quickly without price impact.
At month-end, the firm’s TNC is $2,000,000 and it carries a proprietary long position in XYZ common stock with a market value of $600,000 (standard equity haircut applied separately).
Which statement is INCORRECT under these facts?
Best answer: A
Explanation: Undue concentration concepts focus on the added risk that a large position in a single issuer may not be readily liquidated at or near its quoted value. That incremental liquidation/price-impact risk can require an extra net capital deduction in addition to the product’s standard haircut, even when positions are marked to market daily.
Topic: Function 3 - Customer Protection
Under SEC Customer Protection Rule 15c3-3, a broker-dealer holds customers’ fully paid securities at an unaffiliated foreign bank custodian. The custodian account is titled in the broker-dealer’s name, but there is no written control agreement or other arrangement giving the broker-dealer exclusive control over the securities.
Which choice best describes whether this is likely a control location and the FINOP’s best next step to address possession or control?
Best answer: B
Explanation: A control location is one where the broker-dealer can promptly direct the return of customer securities (directly or through an acceptable control agreement). Title alone does not establish control if the custodian can restrict release. The appropriate FINOP response is to treat the position as not in possession or control and promptly remediate by moving it to a good control location or putting proper control documentation in place.
Topic: Function 2 - Operations, General Securities Industry Regulations, and Preservation of Books and Records
XYZ common stock is distributing transferable subscription rights to existing shareholders. Trades executed on or after the announced ex-rights date are marked “ex-rights” on confirmations. Which statement best matches the “ex-rights” designation as it affects entitlements and delivery?
Best answer: C
Explanation: “Ex-rights” indicates the stock is trading without the attached subscription rights. As a result, delivery/settlement is for the shares only, and the buyer of the shares is not entitled to receive the rights; the seller keeps them. This is an entitlement label that impacts what is delivered with the security.
Topic: Function 2 - Operations, General Securities Industry Regulations, and Preservation of Books and Records
A carrying broker-dealer is a DTC participant and settles most equity trades through DTC’s CNS (book-entry). On settlement date, a customer cash account purchase of 10,000 shares of a DTC-eligible common stock shows as “received via CNS,” but Operations cannot produce any physical certificate or signed delivery receipt. The FINOP must decide how to evidence delivery and how to code the position’s control location for the firm’s stock record and securities count.
Which action is the single best decision consistent with book-entry settlement and customer protection controls?
Best answer: D
Explanation: Book-entry settlement through DTC is effected by electronic debits and credits to the firm’s DTC account, not by movement of physical certificates. Therefore, the firm should evidence delivery with DTC-generated settlement/position reports and reflect DTC as the control location on the stock record and securities count. A missing physical receipt does not, by itself, mean the securities are “in transit” or outside control.
Topic: Function 1 - Financial Reporting
A self-clearing broker-dealer that carries customer accounts uses a customer ledger sub-ledger (by account) that rolls up nightly to the GL control account “Customer credits.” On month-end close day, the FINOP finds the customer credits sub-ledger totals $12.600 million, but the GL control account shows $12.450 million ($150,000 difference). The difference traces to a corporate action cash posting that was booked directly to the GL control account, bypassing the customer sub-ledger; customer statements reflect the credit. The firm uses the GL control account balance in its SEC Rule 15c3-3 reserve computation that will be performed today.
What is the single best FINOP decision?
Best answer: A
Explanation: Control accounts in the general ledger should be supported by, and reconcile to, the underlying sub-ledger that contains the transaction-level detail. Because the customer credit was recorded outside the customer sub-ledger, the roll-up is incomplete and the GL balance used for the Rule 15c3-3 reserve computation is not properly supported. The best decision is to correct the posting path so the sub-ledger and GL control account agree and the reserve computation is based on a validated GL balance.
Topic: Function 3 - Customer Protection
A clearing broker-dealer carries retail customer accounts and also carries omnibus accounts for introducing broker-dealers (PAB accounts). During a reserve computation review, the FINOP finds that PAB accounts were coded as “customer” in the stock record and in the reserve workpapers, so PAB margin debits and credits were included in the customer reserve formula.
Which action best aligns with durable customer protection and books-and-records standards under SEC Rule 15c3-3?
Best answer: B
Explanation: Customer and PAB activity must be allocated correctly in the stock record and reserve workpapers because the reserve formulas rely on those classifications to determine the net credits that must be protected in the appropriate reserve bank account. Misclassifying PAB as customer can understate one reserve and improperly shift protection between the two populations. The FINOP should fix the recordkeeping and recompute/fund based on corrected allocations.
Topic: Function 1 - Financial Reporting
A broker-dealer maintains an accounts payable (A/P) sub-ledger that feeds summary totals into the general ledger (GL). Due to an interface failure, the February A/P sub-ledger balance of $480,000 was not posted to the GL before the FINOP prepared the monthly trial balance and filed the FOCUS report based on the GL.
The net capital computation prepared from the GL shows $150,000 excess net capital. If the missing $480,000 A/P were rolled into the GL, the firm would have a $330,000 net capital deficiency.
What is the most likely consequence of filing based on the unreconciled GL?
Best answer: C
Explanation: Sub-ledgers are not standalone records for reporting purposes; they must reconcile and roll up into the GL that drives the trial balance, financial statements, and FOCUS reporting. If a liability sub-ledger balance is omitted from the GL, liabilities are understated and equity is overstated. Here, that overstatement causes the firm to report excess net capital when it would actually be deficient.
Topic: Function 4 - Net Capital
An introducing broker-dealer computes net capital using the aggregate indebtedness (AI) method. The firm signs a 6-month unsecured note payable to a technology vendor for $1.2 million to fund a systems upgrade. There is no executed subordination agreement and the proceeds will be received next week.
The CFO asks the FINOP to record the note as “paid-in capital” so AI does not increase, noting that net capital is still above the firm’s minimum requirement. Which action best aligns with sound net capital controls and accurate books and records?
Best answer: D
Explanation: Aggregate indebtedness is a high-level leverage measure based on the firm’s liabilities/obligations to others, so it must be captured accurately in the books and reflected in AI monitoring. Even if net capital is currently above the minimum, a material increase in AI can signal rising leverage and liquidity pressure. Proper classification and escalation support reliable regulatory reporting and ongoing compliance.
Topic: Function 4 - Net Capital
For purposes of determining allowable assets under SEC Net Capital Rule 15c3-1, which statement about non-marketable securities is most accurate?
Best answer: A
Explanation: Non-marketable securities are those without a ready market or reliable current pricing and liquidity (often due to limited transferability or the absence of active quotations). Because they are not readily convertible into cash at a determinable value, they are generally treated as non-allowable assets and deducted in the net capital computation under Rule 15c3-1.
Topic: Function 4 - Net Capital
A broker-dealer currently introduces all customer accounts to a clearing firm and relies on an exemption from SEC Customer Protection Rule 15c3-3. During month-end FOCUS preparation, the FINOP is told the firm plans to begin carrying customer accounts next month (holding customer cash and securities at the firm).
Assume that carrying customer accounts raises the firm’s minimum net capital requirement to $250,000 (from $5,000 as an introducing broker) and also requires compliance with Rule 15c3-3. The firm’s current net capital is $80,000.
What is the FINOP’s best next step in the correct sequence?
Best answer: B
Explanation: When a firm starts carrying customer accounts, the FINOP must treat it as a business change that affects both sides of the capital framework: a higher minimum net capital requirement under SEC Rule 15c3-1 and new safeguarding/reserve obligations under SEC Rule 15c3-3. With net capital at $80,000 versus a $250,000 minimum, the firm cannot begin carrying until it is properly funded and the customer protection controls are implemented.
Topic: Function 3 - Customer Protection
A carrying broker-dealer maintains a Special Reserve Bank Account for the Exclusive Benefit of PAB Accounts under SEA Rule 15c3-3. The firm computes its customer reserve weekly but has elected to compute its PAB reserve monthly. Firm policy states that any required deposit or permitted withdrawal must be made no later than the next business day after each reserve computation.
Which statement is INCORRECT regarding how PAB computation frequency interacts with reserve bank account funding?
Best answer: C
Explanation: PAB reserve computation frequency determines how often the required PAB reserve amount is recalculated, but it does not allow the firm to use the PAB reserve bank account as a general funding source between computations. The reserve bank account must remain funded in accordance with the most recent computation, and withdrawals are limited to computed excess amounts.
Topic: Function 4 - Net Capital
A FINOP is reviewing the firm’s haircut support file for a proprietary position. The firm states the haircut treatment was based in part on the security’s liquidity (i.e., trading activity/marketability), and the FINOP must confirm the file contains appropriate support.
Exhibit: Haircut support file index (Position: XYZ common stock)
| Item in file | What it documents |
|---|---|
| Clearing firm position report | Quantity and market value at close |
| Security master record | Security type and primary listing exchange |
| Market data vendor report | Bid/ask and 30-day average daily volume |
| Internal desk email | Trader commentary on “active name” |
Which item most directly supports the firm’s liquidity assumption used in its haircut determination?
Best answer: D
Explanation: Liquidity support for haircuts should be based on objective market evidence of trading activity and pricing (e.g., quotes and average daily volume from an independent source). In the exhibit, only the market data vendor report provides that type of liquidity/marketability documentation for the security.
Topic: Function 5 - Funding and Cash Management
A broker-dealer’s FINOP is preparing a mid-month net capital forecast and identifies a projected shortfall in two weeks. The CFO proposes receiving $2.5 million from the parent as a “loan” that (i) is repayable on 10 days’ notice at the parent’s option and (ii) is secured by a pledge of the firm’s proprietary securities. The CFO asks whether the funds can be treated as regulatory capital once wired in.
What is the FINOP’s best next step?
Best answer: A
Explanation: The proposal is debt-like because it is callable and secured, so it would be recorded as a liability and would not improve net capital under SEC Rule 15c3-1. The FINOP should not rely on the incoming cash for regulatory capital until the funding is structured as a true capital contribution or as a properly subordinated borrowing that can be included in net capital.
Topic: Function 4 - Net Capital
In a broker-dealer net capital context, “business curtailment” most accurately refers to which type of action that may be imposed when capital problems arise?
Best answer: B
Explanation: Business curtailment is a high-level concept describing restrictions that limit what a broker-dealer can do when its capital position deteriorates. The goal is to stop the firm from taking on new risk or paying out cash in ways that could further reduce net capital while the firm restores compliance.
Topic: Function 4 - Net Capital
For purposes of SEC net capital (Rule 15c3-1), which statement about options/derivatives haircuts is most accurate?
Best answer: C
Explanation: Net capital haircuts are designed to cover potential market losses on positions, including options and other derivatives. When positions are properly offset or hedged, the firm’s net market exposure is lower, so the net haircut is lower. Separately, if customer-related option exposure is under-margined, the deficiency increases the firm’s unsecured risk and results in additional net capital impact.
Topic: Function 4 - Net Capital
While preparing the broker-dealer’s monthly net capital computation under SEC Rule 15c3-1, the FINOP reviews the trial balance and notices a $150,000 “Prepaid technology subscription (12-month contract)” recorded in Other Current Assets. The contract is non-cancelable and the vendor will not refund any unused amounts.
Which action best aligns with net capital standards and accurate regulatory reporting?
Best answer: D
Explanation: Prepaid expenses for nonrefundable services are not readily convertible into cash, so they are treated as non-allowable assets for net capital purposes. To keep the net capital computation accurate, the FINOP should ensure the prepaid amount is properly classified and fully deducted from net worth when computing net capital.
