Sample questions

Question 1

A broker-dealer is currently a fully disclosed introducing firm that does not receive or hold customer funds or securities. Management plans to amend its clearing arrangement effective July 1 so the firm will carry customer accounts, maintain custody of customer fully paid securities at a control location, and hold customer cash (i.e., it will be subject to SEC Customer Protection Rule 15c3-3). The firm’s most recent computed net capital is $190,000, and its pro forma computed net capital as of July 1 is $210,000.

Assume the minimum net capital standards are: $5,000 for an introducing firm that does not receive/hold customer funds or securities; $25,000 for an introducing firm that receives (but does not carry) customer funds/securities; and $250,000 for a carrying firm. What is the single best FINOP decision regarding the firm’s minimum net capital requirement and go-live plan?

• A. Apply the $5,000 minimum because it will introduce most trades
• B. Go live July 1 and cure any minimum net capital shortfall within 5 business days
• C. Apply the $250,000 minimum and do not go live until net capital is at least $250,000
• D. Apply the $25,000 minimum because it will still use an outside clearing firm

Best answer: C

Explanation: Because the firm will carry customer accounts and be subject to Rule 15c3-3, it must meet the carrying-firm minimum before commencing the business.

Minimum net capital is driven by the firm’s business model—introducing versus carrying—not by whether it routes trades through another firm. Once the firm will carry customer accounts and hold customer funds/securities (triggering Rule 15c3-3), it is treated as a carrying firm for minimum net capital purposes. With pro forma net capital of $210,000, it must raise capital or delay the conversion.

A FINOP should tie the minimum net capital requirement to what the firm actually does with customer accounts. Introducing firms that do not receive/hold customer funds or securities have a much lower minimum, while firms that carry customer accounts (and therefore must maintain possession or control and a reserve framework under SEC Rule 15c3-3) are subject to a substantially higher minimum net capital requirement.

Here, the planned July 1 change makes the firm a carrying firm because it will hold customer cash and custody customer fully paid securities at a control location. Using another firm for execution or certain clearing functions does not change that classification. Since the pro forma computed net capital ($210,000) is below the stated $250,000 minimum, the firm should not commence carrying activities until it has adequate net capital (e.g., via a permitted capital contribution/subordination) and can demonstrate ongoing compliance.

• Wrong classification: treating a carrying arrangement as “introducing” ignores that holding customer funds/securities drives the higher minimum.
• Focus on trade flow: introducing “most trades” is irrelevant when the firm will carry accounts and custody assets.
• Cure period assumption: operating while below the stated minimum violates the financial responsibility control that net capital must be met on an ongoing basis.

Question 2

In the context of SEC Net Capital Rule 15c3-1, which statement best describes a security with a “ready market” and why that matters for net capital treatment?

• A. It can be sold promptly at a reasonably ascertainable price, so it is generally eligible for standard market-value haircuts rather than being treated as illiquid/non-allowable
• B. It is any security held at a control location, so it is treated as cash-equivalent for net capital
• C. It is any listed security, so it is always fully allowable and never subject to additional deductions
• D. It is any security carried at fair value on GAAP financial statements, so no haircut is required

Best answer: A

Explanation: A ready market supports reliable pricing and liquidity, which drives whether a position receives normal haircuts versus punitive treatment (including possible 100% haircut/non-allowable).

A “ready market” is about liquidity and price transparency: the firm can reasonably determine current market value and could sell the position promptly. Because net capital focuses on how quickly assets can be converted to cash under stress, positions lacking a ready market typically receive much more conservative treatment (including very large haircuts or being treated as effectively non-allowable).

Under SEC Rule 15c3-1, a “ready market” conceptually means there are observable, bona fide market prices (e.g., from independent market makers/quotations or active trading) and the position can be liquidated promptly at a reasonably ascertainable price. This matters because net capital haircuts are meant to reflect potential liquidation risk. When a security has a ready market, the broker-dealer generally applies the applicable market-risk haircut to its market value. When a security does not have a ready market, the firm may not be able to reliably price or promptly liquidate it; as a result, it is treated much more conservatively for net capital purposes—often through a punitive haircut (up to a full deduction) and, in effect, reduced or eliminated capital value.

• GAAP fair value confusion: Financial statement valuation does not eliminate regulatory haircuts under the net capital rule.
• “Listed equals liquid” overreach: Exchange listing alone does not guarantee sufficient liquidity/price reliability for net capital purposes.
• Control location mix-up: Control location affects possession/control and custody concepts, not whether a position has a ready market for haircut purposes.

Question 3

An introducing broker-dealer (self-clearing for books but uses a clearing firm for settlement) shows a sharp increase in failed-to-deliver positions from customer sells that were allocated incorrectly and not resolved promptly. The clearing firm has begun passing through daily fail charges, and the FINOP notes that several fails have remained open beyond the firm’s internal “aged fail” threshold, at which point the firm applies an operational charge (deduction) in its SEC Net Capital Rule 15c3-1 computation.

Which is the PRIMARY risk/red flag the FINOP should focus on?

• A. A net capital deficiency risk from operational charge deductions tied to aged fails
• B. A CIP/AML breakdown requiring immediate SAR filing
• C. An automatic customer reserve underfunding under Rule 15c3-3
• D. A Regulation S-P privacy violation from trade allocation errors

Best answer: A

Explanation: Aged fails can trigger operational charge deductions, reducing net capital and requiring heightened monitoring and escalation.

Fail charges and “aged” fails are a classic FINOP red flag because unresolved settlement fails can become operational charge deductions in the 15c3-1 net capital computation. As aged fails accumulate, deductions can materially reduce net capital and increase the risk of a net capital deficiency. The pattern also signals weak trade processing and fail management controls that warrant heightened supervisory focus.

The core issue is the relationship between settlement failures and net capital. Fail charges are economic penalties associated with unresolved fails (often passed through by a clearing firm), and a growing population of long-outstanding fails is a control breakdown indicator (allocation/clearance/reconciliation). Under the SEC Net Capital Rule 15c3-1 framework, “aged” fails can require operational charge treatment (a deduction) because the longer a fail remains unresolved, the less reliable it is as a collectible/settled position.

For a FINOP, the practical risk is that:

• aged fails increase operational charge deductions,
• deductions reduce net capital (and can pressure minimum requirements), and
• the trend signals the need for escalation, tighter reconciliations, and timely fail resolution.

The key takeaway is that aged fails are primarily a net capital and operational control risk, not automatically a customer reserve or privacy/AML issue.

• Reserve underfunding is not automatic; fails may affect possession/control or reserve only based on the specific customer protection facts, which are not provided.
• AML/CIP is not the central issue; allocation and settlement fails do not, by themselves, create a SAR requirement.
• Privacy is not the primary red flag here; misallocations create operational and net capital exposure rather than a Regulation S-P event on these facts.

Question 4

A broker-dealer’s FINOP prepares a midday net capital check after a trading loss. All amounts are in USD.

Exhibit: Net capital workpaper (midday)

Firm policy (implementing SEC Rule 15c3-1/FINRA notification expectations) states: if net capital is below the minimum requirement at any time, the FINOP must notify FINRA (DEA) immediately upon discovery and then send written notice within 24 hours.

Based on the exhibit, what should the FINOP do next?

• A. Notify only the clearing firm because it carries customer accounts
• B. Defer notification and disclose the deficit on the next FOCUS filing
• C. Immediately notify FINRA (DEA) of a net capital deficiency
• D. Wait to notify until the close because net capital can change intraday

Best answer: C

Explanation: Net capital is $235,000, which is $15,000 below the $250,000 minimum, requiring immediate notification upon discovery.

Compute net capital as net worth less non-allowable assets and less haircuts: $460,000 − $120,000 − $105,000 = $235,000. Because $235,000 is below the $250,000 minimum, the firm is in net capital deficiency. Under the stated policy tied to SEC Rule 15c3-1/FINRA expectations, the FINOP must escalate and notify FINRA immediately upon discovery.

A FINOP’s escalation obligation is driven by whether the firm is meeting its minimum net capital requirement at the time the calculation is performed, not whether the deficiency might be cured later. Using the exhibit, net capital is computed by subtracting non-allowable assets and required haircuts from GAAP net worth, then comparing the result to the minimum requirement.

Since $235,000 is below the $250,000 minimum, a deficiency exists and the FINOP must promptly notify the DEA (FINRA) per the stated immediate-notification standard and pursue corrective action; waiting for end-of-day changes does not satisfy timely escalation.

• Wait for intraday changes is not acceptable when the calculation already shows a current deficiency under the firm’s stated immediate-notification standard.
• Next FOCUS disclosure is periodic reporting and does not replace required prompt deficiency notification.
• Notify only the clearing firm may be operationally prudent, but it does not satisfy the firm’s obligation to notify its DEA.

Question 5

During daily net capital monitoring while preparing the month-end FOCUS support, the FINOP identifies a margin account where the customer’s debit balance is $420,000 and the market value of margin securities is $300,000 (a $120,000 margin deficit). Operations confirms the deficit is not a booking error and no funds are expected today. The firm’s excess net capital cushion is thin.

What is the FINOP’s best next step in the correct sequence?

• A. Take a net capital deduction for the deficit and initiate collection action
• B. Defer any net capital impact until the deficit is 30 days old
• C. Treat the deficit as a reserve requirement item and increase the reserve deposit
• D. Offset the deficit with firmwide customer credit balances and take no action

Best answer: A

Explanation: A confirmed margin deficit represents an unsecured exposure that can require a net capital charge and prompt cure actions (margin call/close-out).

A confirmed margin deficit indicates the customer has not provided required equity, leaving the broker-dealer with an unsecured receivable/exposure. Under the Net Capital Rule (SEC Rule 15c3-1), that exposure can require a regulatory charge that reduces net capital. The FINOP should reflect the deduction in the computation and ensure prompt action to collect funds or liquidate positions to eliminate the deficit.

Margin deficits are operationally important to a FINOP because they can create unsecured customer exposure and inflate assets that may not be fully collectible. Once a deficit is confirmed (not a recon break), it generally cannot be ignored for regulatory reporting: it can trigger a net capital deduction/charge under SEC Rule 15c3-1 and requires prompt corrective action under margin procedures (e.g., issuing/monitoring a margin call and escalating to liquidation/close-out if not satisfied). The workflow is to (1) validate the deficit, (2) reflect the appropriate net capital impact in the firm’s computation/FOCUS support, and (3) drive timely remediation so the exposure does not persist and further pressure net capital.

Key takeaway: curing the deficit and recognizing its regulatory impact go hand-in-hand; postponing either step increases risk of non-compliance.

• Wait for aging fails because a confirmed deficit can require an immediate regulatory charge and prompt action.
• Reserve account confusion fails because customer reserve funding is a separate Customer Protection Rule process, not the treatment of an under-margined debit.
• Improper netting fails because firmwide credits do not eliminate a specific customer’s unsecured margin exposure for net capital purposes.

Question 6

Firm Alpha clears and carries customer accounts, holds customer fully paid securities at a custodian in its name, and receives customer funds for settlement and margin.

Firm Beta is a fully disclosed introducing broker that sends all customer trades to an unaffiliated clearing firm and does not receive or hold customer funds or securities.

For this question, assume: a broker-dealer that carries customer accounts has a .25,000 minimum net capital requirement and is subject to SEC Rule 15c3-3; a fully disclosed introducing broker that does not carry customer accounts has a $5,000 minimum net capital requirement and is generally exempt from Rule 15c3-3.

Which option correctly matches each firm to its regulatory treatment?

• A. Alpha and Beta: $5,000 minimum net capital; both generally exempt from Rule 15c3-3
• B. Alpha: $250,000 min; Rule 15c3-3 applies. Beta: $5,000 min; generally exempt
• C. Alpha: $5,000 min; generally exempt. Beta: $250,000 min; Rule 15c3-3 applies
• D. Alpha and Beta: $250,000 minimum net capital; Rule 15c3-3 applies to both

Best answer: B

Explanation: Carrying customer accounts is the decisive factor that drives both the higher minimum net capital category and Rule 15c3-3 customer protection obligations.

A firm that clears and carries customer accounts typically has custody/settlement responsibilities for customer funds and securities, which triggers SEC Rule 15c3-3 (reserve/possession or control framework) and places the firm in a higher minimum net capital category. A fully disclosed introducing broker that does not hold customer assets is generally exempt from Rule 15c3-3 and can qualify for a lower minimum net capital requirement under the stated assumptions.

The key differentiator is whether the broker-dealer is carrying customer accounts (i.e., it holds customer funds/securities and performs clearance/settlement or margin financing). Carrying firms must operate customer protection controls under SEC Rule 15c3-3, such as safeguarding customer securities and segregating customer cash through reserve mechanics, because customer assets are at the firm or in locations controlled by the firm.

That same “carrying” status also affects minimum net capital under SEC Rule 15c3-1: firms with direct customer asset responsibility are placed in higher minimum net capital categories than fully disclosed introducing brokers that neither receive nor hold customer funds or securities.

Under the question’s stated assumptions, Alpha is the carrying firm and Beta is the fully disclosed non-carrying firm, so their minimum net capital and Rule 15c3-3 treatments differ accordingly.

• Inverted classifications swaps the carrying vs fully disclosed introducing roles, reversing both net capital category and Rule 15c3-3 treatment.
• Both subject to Rule 15c3-3 ignores that a fully disclosed introducing broker that does not hold customer assets is generally exempt under the assumption provided.
• Both lower minimum net capital conflicts with the stated assumption that carrying customer accounts places a firm in the higher minimum net capital category.

Question 7

A carrying broker-dealer’s AI-monitoring dashboard (built from an AI GL-classification model) flags an unusual decrease in Aggregate Indebtedness (AI) for month-end, even though financing activity was unchanged. On review, the FINOP sees:

Exhibit: Month-end snapshot (USD)

GL balances (liabilities)
- Notes payable—bank (unsecured, demand; no subordination agreement)   $10,000,000
- Accrued interest payable on bank note                               $    50,000
- Other current liabilities                                            $ 6,000,000

AI schedule produced by the AI model
- AI included                                                        $ 6,000,000
- Items excluded as "Subordinated borrowing"                          $10,050,000

Which statement or action is INCORRECT based on SEC Rule 15c3-1 AI concepts?

• A. Reclassify the bank note as AI and correct the AI model’s mapping
• B. Assess whether regulatory reports were misstated and escalate for possible amendment
• C. Ensure the accrued interest payable is recorded and included in AI
• D. Exclude the bank note from AI because borrowings are not “indebtedness”

Best answer: D

Explanation: An unsecured bank note without an approved subordination agreement is a liability included in AI.

Aggregate Indebtedness generally includes unsecured liabilities unless they are properly subordinated under an effective subordination agreement. Here, the AI tool excluded an unsecured bank note (and its interest accrual) as if it were subordinated, which would understate AI. The FINOP should correct the classification/mapping and ensure liabilities (including accruals) are properly reflected for regulatory reporting.

For AI under SEC Rule 15c3-1, the key question is whether a liability is truly subordinated in a manner that qualifies for exclusion from AI. An unsecured bank note that is demand/callable and has no executed, effective subordination agreement is not subordinated for net capital purposes, so it remains a liability included in AI; related accrued interest payable is also an AI liability. In this scenario, the AI anomaly is most consistent with a classification/mapping error (treating the note as “subordinated borrowing”) and a potential accrual completeness issue if the interest wasn’t being captured consistently. The appropriate corrective action is to fix the GL-to-AI mapping, validate accruals, and evaluate whether any filed schedules were misstated and require escalation/remediation.

• “Borrowings aren’t indebtedness” fails because unsecured notes payable are indebtedness for AI unless properly subordinated.
• Fix mapping/classification is appropriate because the exhibit shows the model excluded a non-subordinated liability.
• Include interest accrual is appropriate because accrued expenses and interest payable are AI liabilities.
• Escalate/reporting impact is appropriate because an AI understatement can affect FOCUS/net capital reporting accuracy.

Question 8

A broker-dealer currently operates as an introducing firm and does not receive customer funds or securities. The FINOP has documented that its minimum net capital requirement under SEC Rule 15c3-1 is $25,000.

Management proposes a new process in which customers will wire funds into the broker-dealer’s bank account and the firm will transmit those funds to its clearing firm the next business day. For purposes of this question, assume a firm that receives customer funds has a $50,000 minimum net capital requirement.

Which statement is most accurate/correct?

• A. The minimum net capital requirement remains $25,000 because the firm is still introducing through a clearing firm.
• B. Receiving customer funds would increase the minimum net capital requirement to $50,000, and the FINOP should escalate the change before implementation to ensure funding and ongoing compliance.
• C. A higher minimum net capital requirement would apply only if the firm begins market making.
• D. The firm can implement the change and address any minimum net capital shortfall at month-end when preparing the FOCUS Report.

Best answer: B

Explanation: The business change triggers a higher stated minimum, so the FINOP should escalate pre-launch to ensure the firm can meet the new requirement continuously.

Minimum net capital requirements can change when a broker-dealer changes how it handles customer assets. Here, the new process causes the firm to receive customer funds, which (per the assumption provided) raises the minimum net capital requirement from $25,000 to $50,000. A prudent FINOP response is to escalate before implementation and confirm sufficient capital/funding to remain in compliance at all times.

A FINOP must evaluate whether a proposed business change alters the firm’s minimum net capital requirement under SEC Rule 15c3-1 and escalate early enough to prevent operating out of compliance.

In this scenario, the firm is moving from not receiving customer funds to receiving customer funds (even briefly) through its own bank account. Under the assumption given, that activity change increases the minimum net capital requirement to $50,000. The prudent escalation step is to notify/engage senior management (and other control partners as appropriate) before launch so the firm can either (1) fund the higher minimum (e.g., capital contribution/subordination) or (2) redesign the process to avoid receiving customer funds.

Net capital compliance is continuous, not something cured after the fact through reporting.

• Still introducing is not determinative; receiving customer funds is the stated driver of the higher minimum.
• Fix it at month-end fails because minimum net capital must be met at all times, not just at reporting.
• Only market making triggers changes is incorrect; different activities (like receiving customer funds) can change the minimum.

Question 9

A FINOP is training a new analyst on why the firm tracks aggregate indebtedness (AI) along with net capital under SEC Rule 15c3-1. Which description best matches the purpose and high-level meaning of AI in that context?

• A. AI is net capital after applying securities haircuts and non-allowable asset deductions
• B. AI is the firm’s total indebtedness (generally liabilities/obligations) used as a leverage and liquidity stress indicator when compared to net capital
• C. AI is the customer reserve requirement amount that must be deposited in the Special Reserve Bank Account
• D. AI is the market-risk haircut percentage applied to proprietary positions to adjust net worth

Best answer: B

Explanation: AI captures overall indebtedness, and monitoring it against net capital helps identify excessive leverage that can pressure liquidity and capital compliance.

Aggregate indebtedness is a high-level measure of a broker-dealer’s overall indebtedness (generally its liabilities/obligations). It is monitored alongside net capital because the relationship between indebtedness and net capital is a practical leverage and liquidity early-warning indicator: rising obligations without commensurate capital can signal funding strain and potential net capital issues.

Under the net capital framework, AI is a broad measure of how much the broker-dealer owes (its indebtedness), viewed at a high level as total liabilities/obligations rather than a market-risk adjustment. FINOPs monitor AI together with net capital because net capital shows the firm’s regulatory capital cushion, while AI reflects the scale of obligations that must be funded and paid. A firm can have positive net capital but still become stressed if its indebtedness grows disproportionately, so comparing AI to net capital helps highlight excessive leverage and potential liquidity pressure before it becomes a net capital deficiency. The key is that AI is about indebtedness; haircuts and reserve computations are different controls aimed at different risks.

• Confusing AI with net capital misses that AI measures indebtedness, while net capital is capital after deductions and haircuts.
• Customer reserve mix-up describes the SEC Rule 15c3-3 reserve computation and deposit requirement, not AI.
• Haircut concept mix-up describes market-risk deductions applied in the net capital computation, not a measure of liabilities.

Question 10

A carrying broker-dealer is subject to a 15:1 aggregate indebtedness (AI) limit. In preparing its FOCUS filing, the FINOP treats an affiliate loan as excluded from AI because a subordination agreement was signed. However, the loan has not been approved as an SEC/FINRA-approved subordinated loan.

Facts (USD):

• Net capital: $1,000,000
• AI (excluding the affiliate loan): $14,000,000
• Affiliate loan payable: $2,000,000

What is the most likely consequence of excluding the affiliate loan from AI?

• A. There is no regulatory impact as long as the loan is from an affiliate and documented in writing
• B. AI is overstated because subordinated loans must always be included in AI until maturity
• C. Net capital increases, but AI is unchanged because only balance-sheet assets affect AI
• D. AI is understated; if corrected, the firm would exceed its AI limit and face a required notification/restriction

Best answer: D

Explanation: Only approved subordinated loans are excluded from AI, so treating an unapproved loan as excluded can mask an AI ratio breach and trigger corrective action once detected.

Approved subordinated loans are excluded from aggregate indebtedness because they function as regulatory capital rather than repayable indebtedness. An unapproved affiliate loan does not qualify for that exclusion and must be treated as a liability for AI purposes. Including it would increase AI enough to push the firm over its stated AI limit, creating regulatory exposure and prompting required escalation and corrective action.

Aggregate indebtedness generally includes a broker-dealer’s liabilities, but certain items are excluded because they are treated more like regulatory capital than debt. A key exclusion is an SEC/FINRA-approved subordinated loan: once properly approved, it is subordinated to customers and general creditors and is restricted from repayment in a way that supports the firm’s financial responsibility.

Here, the affiliate loan is not approved, so it cannot be excluded from AI. If it is included, AI becomes $16,000,000 ($14,000,000 + $2,000,000), and the AI ratio becomes 16:1 ($16,000,000 / $1,000,000), exceeding the 15:1 limit stated in the facts. The consequence is an inaccurate regulatory filing and a situation that requires prompt escalation and corrective steps to address the AI limit breach.

• Approval matters: the exclusion applies to approved subordinated borrowings; merely signing an agreement is not enough.
• Not a maturity rule: the issue is regulatory approval/qualification, not that subordinated loans are “always included until maturity.”
• AI is liability-driven: AI is not determined solely by assets; liabilities (including unapproved borrowings) are central to the calculation.
• Documentation alone is insufficient: affiliate status and a written note do not make a borrowing excludable from AI.
