Series 28 Scenario Practice Guide

How to Approach Series 28 Scenario Questions

The FINRA Series 28, the Introducing Broker-Dealer Financial and Operations Principal Qualification Examination, tests more than memorized terms. Scenario questions often ask you to apply financial responsibility, recordkeeping, reporting, operational, and supervisory concepts to a specific broker-dealer situation.

A strong scenario answer usually comes from a disciplined reading process:

1. Identify the firm type and role.
2. Find the actual decision point.
3. Separate operationally relevant facts from background noise.
4. Check authority, documentation, timing, and required records.
5. Apply the rule or accounting treatment to the facts given.
6. Choose the answer that best protects accurate books, required reporting, and regulatory compliance.

Start With the Role: Who Is Acting and What Firm Is Involved?

Series 28 scenarios are often written from the perspective of an introducing broker-dealer’s financial and operations function. Before doing any calculation or selecting a procedure, clarify the setting.

Ask:

• Is the firm an introducing broker-dealer?
• Does the firm carry customer accounts, or does another firm perform clearing and custody functions?
• Is the person acting as a financial and operations principal, operations manager, registered representative, bookkeeper, principal, auditor, or clearing firm contact?
• Is the question about the introducing firm’s own books and records, or about customer account activity handled through a clearing arrangement?
• Is the issue financial responsibility, reporting, account records, supervisory controls, or communication with a regulator or clearing firm?

This matters because the best answer depends on the firm’s responsibility in the fact pattern. A choice that sounds correct for a carrying broker-dealer may not be the most defensible answer for an introducing broker-dealer scenario.

Role Clues to Mark Mentally

When reading, slow down around phrases such as:

• “The introducing broker-dealer…”
• “The clearing firm…”
• “The FOP discovers…”
• “The firm’s books show…”
• “A customer complaint alleges…”
• “Prior to filing…”
• “During month-end close…”
• “The firm receives notice from…”
• “An associated person fails to…”

These phrases tell you whose obligation is being tested.

Find the Actual Decision Point

Many Series 28 scenarios include financial data, operational facts, and regulatory terms. Do not let the first familiar phrase pull you into answering too early.

After reading the stem, state the question in your own words:

• “What must the firm record?”
• “What report or notice is required?”
• “How should this item be treated for net capital purposes?”
• “What should the FOP do next?”
• “Which record must be maintained?”
• “Which fact changes the firm’s required action?”
• “Which answer is consistent with the introducing firm’s responsibilities?”

The actual decision point is often narrower than the story. A scenario may mention a customer trade, a clearing firm, a capital contribution, and a failed reconciliation, but the question may only ask about the next supervisory or reporting step.

A Useful One-Sentence Test

Before looking at the answer choices, complete this sentence:

“The exam is asking me to decide whether the firm should _____ based on _____.”

Examples:

• “The exam is asking me to decide whether the asset is allowable based on its liquidity and collectability.”
• “The exam is asking me to decide whether a regulatory notice is required based on the financial condition described.”
• “The exam is asking me to decide which record must be maintained based on the transaction or account event.”
• “The exam is asking me to decide what the FOP should do next based on an unresolved books-and-records discrepancy.”

If you cannot complete that sentence, reread the final line of the question.

Classify the Scenario Before Solving It

Series 28 scenarios are easier when you first classify the problem. Most questions fit into one of several practical categories.

Financial Responsibility and Net Capital

For questions involving capital, assets, liabilities, haircuts, subordinated agreements, receivables, or expense accruals, focus on the firm’s financial condition.

Ask:

• What is the firm required to measure?
• Is the question asking for a computation, a treatment, or an action?
• Are assets allowable or non-allowable?
• Are liabilities properly recorded?
• Are deductions, charges, or haircuts required?
• Is the issue a deficiency, early warning condition, or recordkeeping problem?
• Does the question provide the numerical rule or threshold you need?

If the stem gives numbers, do not rush into arithmetic. First decide what belongs in the calculation.

Books, Records, and Reconciliations

For recordkeeping questions, identify the record and the event that creates or changes it.

Ask:

• What transaction, account change, ledger entry, or operational event occurred?
• Which record would reflect that event?
• Is the issue creation, accuracy, retention, correction, or supervisory review?
• Is there a discrepancy between the general ledger, blotter, bank account, clearing statement, or customer information?
• What is the most direct way to correct or escalate the issue?

The best answer often supports accurate books and records rather than a quick informal fix.

Regulatory Reporting and Notices

For reporting scenarios, focus on timing, completeness, and who must receive the information.

Ask:

• Is the firm filing a periodic financial report?
• Has an event occurred that may require notice?
• Is the issue discovery, documentation, filing, amendment, or supervisory approval?
• Does the answer choice preserve accuracy before submission?
• Is the firm trying to delay, omit, estimate, or conceal material information?

A defensible Series 28 answer usually favors accurate and timely reporting over convenience.

Operational Supervision and Controls

For control-related scenarios, identify the weakness and the required response.

Ask:

• What control failed or was bypassed?
• Who discovered the issue?
• Is the issue isolated, recurring, or unresolved?
• Does the FOP have enough information to conclude, or is investigation required?
• Is supervisory review, documentation, escalation, or correction needed?
• Does the answer strengthen controls without exceeding the role described?

The best answer is usually the one that addresses the control issue directly and creates a clear record of the action taken.

Separate Relevant Facts From Distractors

Scenario questions often include facts that are true but not decisive. In Series 28, distractors may appear as extra account details, customer background, product names, dates, or operational descriptions that do not affect the required financial or reporting treatment.

A fact is likely relevant if it affects:

• Firm classification or responsibility.
• Capital treatment.
• Allowable versus non-allowable assets.
• Liability recognition.
• Required books and records.
• Report filing or notice obligation.
• Supervisory approval or review.
• Customer or firm account distinction.
• Clearing versus introducing firm responsibility.
• Documentation needed to support an entry or action.

A fact is less likely to be decisive if it merely adds color, such as:

• The customer’s occupation when the issue is a firm ledger entry.
• The trade size when the issue is report retention.
• The product name when the issue is whether a receivable is collectible.
• The branch location when the issue is a firm-wide financial report.
• A date that does not affect timing, aging, filing, or retention.

Do not ignore details, but give priority to the facts that change the required answer.

Read Financial Data in a Controlled Sequence

Series 28 scenarios may include trial balance items, receivables, payables, securities positions, deposits, commissions, expenses, capital contributions, or clearing balances. A disciplined order helps prevent careless treatment.

Use this sequence:

1. Identify the measurement. Are you calculating net capital, aggregate indebtedness, excess capital, a deduction, a reserve item, or a reportable amount?
2. Sort assets. Which assets are cash or readily available? Which may be non-allowable, aged, unsecured, prepaid, fixed, or unsupported?
3. Sort liabilities. Which liabilities must be recorded or accrued? Are expenses, payables, or obligations omitted?
4. Apply required deductions or charges. Use the rule or percentage supplied in the question or the exam content you have studied.
5. Check the timing. Is the item current, aged, pending, settled, failed, or unresolved?
6. Compare to the question’s required outcome. Do not compute more than the stem asks for.

Mini Example: Financial Treatment

A scenario states that an introducing broker-dealer has a receivable from an affiliated entity, and the question asks how the item should be treated in a capital computation.

Before choosing an answer, ask:

• Is the receivable collectible and properly documented?
• Is it from a customer, broker-dealer, affiliate, employee, or other party?
• Is it secured or unsecured?
• Is it aged?
• Does the question ask for accounting entry, net capital treatment, or supervisory action?

The answer should match the treatment required by those facts, not just the word “receivable.”

Check Authority and Documentation

Series 28 scenarios frequently test whether a firm has proper support for an action. Documentation is not just administrative. It is often the evidence that the firm’s financial records, regulatory filings, and supervisory decisions are defensible.

Look for:

• Written agreements.
• Clearing agreements.
• Subordination documentation.
• Account records.
• General ledger support.
• Bank statements.
• Reconciliations.
• Trial balances.
• Expense accruals.
• Supervisory approvals.
• Regulatory filings and amendments.
• Evidence of review or escalation.

When a scenario describes an undocumented arrangement, unsupported journal entry, unresolved discrepancy, or informal approval, the best answer often requires proper documentation or escalation before relying on the item.

Authority Questions to Ask

• Who is authorized to approve the action?
• Does the firm have written support?
• Is the approval internal, external, regulatory, or contractual?
• Is the action effective now, or only after required conditions are satisfied?
• Is the record complete enough to support the firm’s books and filings?

If an answer choice assumes authority that the scenario does not provide, be cautious.

Look for Suitability, Disclosure, and Customer Protection Clues Carefully

Although Series 28 is not primarily a sales-practice exam, operational and financial responsibility questions can still include customer-related facts. Read those facts through the lens of the firm’s operational obligations.

Relevant customer-related clues may include:

• Whether customer funds or securities are involved.
• Whether the firm introduces accounts to a clearing firm.
• Whether a customer complaint identifies a books-and-records or supervisory issue.
• Whether account documentation is incomplete.
• Whether customer balances, credits, or debits appear in firm records.
• Whether a disclosure, confirmation, statement, or account record is implicated.
• Whether customer assets are commingled with firm assets.
• Whether a registered representative’s conduct affects the firm’s records or financial reporting.

Do not jump to a sales-practice answer unless the question actually asks for it. For Series 28, the key issue may be how the firm records, reports, reconciles, supervises, or escalates the customer-related event.

Choose the Answer That Fits the Entire Scenario

Good answer choices may contain correct statements, but only one is usually the best response to the specific facts. The most defensible answer should satisfy the scenario as a whole.

Before selecting, test each choice against four questions:

1. Does it answer the actual question asked?
2. Does it match the firm’s role as an introducing broker-dealer?
3. Does it preserve accurate books, records, and reporting?
4. Does it respect required authority, documentation, and timing?

If an answer is true but incomplete, too broad, too narrow, or assigned to the wrong party, it is usually not the best answer.

Prefer Answers That Are Operationally Defensible

In Series 28 scenarios, the best answer often does one or more of the following:

• Corrects or supports the firm’s financial records.
• Requires appropriate review before filing.
• Treats an asset, liability, or deduction consistently with the facts.
• Escalates a material issue to the proper person or function.
• Documents the basis for a financial or operational decision.
• Maintains required records.
• Recognizes the introducing firm’s responsibilities without assuming carrying functions.
• Addresses a deficiency rather than ignoring it.

Be skeptical of answers that:

• Rely on informal verbal approval.
• Delay action without a reason.
• Ignore an unresolved discrepancy.
• Treat unsupported items as acceptable.
• Shift responsibility without basis.
• Choose convenience over accurate books and records.
• Answer a different question than the one asked.

Use the Final Line of the Question as Your Anchor

The final line often tells you whether the scenario is asking for:

• The best next action.
• The correct treatment of an item.
• The required record.
• The filing or notice implication.
• The responsible party.
• The effect on net capital or financial condition.
• The supervisory response.
• The most appropriate documentation.

When answer choices seem close, return to the final line. A question asking “What should the FOP do first?” is different from “How should the item be treated?” and different again from “Which report is affected?”

“First,” “Best,” and “Most Appropriate”

These words matter.

• First usually asks for the immediate next step, such as verify, document, escalate, or correct before taking later action.
• Best usually asks for the most complete and defensible response.
• Most appropriate usually requires matching the answer to role, timing, authority, and facts.
• Except or not changes the task completely. Slow down and restate the question before answering.

Handling Calculation-Based Scenarios

Calculation questions can be straightforward if you control the setup. The danger is not the math itself; it is including the wrong items.

Use a three-pass method:

Pass 1: Label the Data

Mark each amount as one of the following:

• Cash or cash equivalent.
• Receivable.
• Payable or accrued expense.
• Securities position.
• Deposit or prepaid item.
• Fixed or illiquid asset.
• Capital contribution or withdrawal.
• Subordinated obligation.
• Clearing balance.
• Customer-related balance.
• Firm expense or revenue.

Pass 2: Decide the Treatment

For each item, ask:

• Is it included, deducted, adjusted, or ignored for this calculation?
• Is there a haircut, charge, or reserve treatment?
• Does aging or collectability affect the treatment?
• Does documentation affect whether the item can be recognized?
• Does the item belong to the firm or to a customer?
• Has the liability already been recorded?

Pass 3: Answer the Specific Question

Only after labeling and treatment should you calculate. Then confirm the question asks for the number you computed.

For example, if the stem asks for “excess capital,” do not stop at total capital. If it asks for the “effect” of an adjustment, do not recompute unrelated balances unless needed.

Handling “Best Next Action” Scenarios

When the question asks what the FOP should do next, think like a principal responsible for accurate financial and operational controls.

A practical sequence is:

1. Stop relying on unsupported information.
2. Verify the facts from primary records.
3. Correct the books if the issue is confirmed.
4. Assess whether reporting, notice, or escalation is required.
5. Document the review and action taken.

The best next action is not always the final resolution. Sometimes the immediate answer is to investigate or obtain support before filing, booking, releasing funds, or treating an item as allowable.

Mini Example: Unresolved Reconciliation

A scenario says the monthly bank reconciliation shows a difference that staff cannot explain, and the firm is preparing a financial filing.

A defensible approach is to ask:

• Is the difference material to the filing?
• Has the firm identified whether the error is in the bank record, ledger, deposit, check, wire, or journal entry?
• Is a correcting entry supported?
• Must the filing wait for accurate books, or must a notice or amendment be considered?
• Who must review the unresolved item?

Avoid choosing an answer that simply ignores the difference because the firm is near a deadline.

Handling Reporting and Filing Scenarios

For reporting questions, identify the event that triggers action and the status of the information.

Ask:

• Is this a periodic report, an amendment, or an event-driven notice?
• Is the information final, estimated, disputed, or incomplete?
• Who is responsible for review before submission?
• Does the scenario show a financial condition issue?
• Does the firm need to correct records before filing?
• Is the issue internal only, or does it require external reporting?

A strong answer should preserve both timeliness and accuracy. If the answer choices force a choice, select the one that most directly satisfies the reporting obligation described by the facts.

Handling Clearing and Introducing Firm Scenarios

Because the Series 28 exam concerns introducing broker-dealers, scenarios may test how responsibilities are divided between the introducing firm and the clearing firm.

Read carefully for:

• Who holds customer funds or securities.
• Who sends confirmations or statements.
• Who maintains which records.
• Who performs clearing and settlement functions.
• What the clearing agreement assigns to each party.
• What the introducing firm must still supervise, record, or reconcile.
• Whether the issue involves the introducing firm’s own financial records.

Do not assume the clearing firm handles everything. Also do not assume the introducing firm has carrying-firm obligations unless the facts indicate that role.

Practical Question

Ask:

“Even if the clearing firm performs this function, what must the introducing broker-dealer still record, review, supervise, disclose, or reconcile?”

That question often points to the best Series 28 answer.

Handling Books-and-Records Scenarios

Books-and-records questions often turn on what evidence the firm must maintain and whether the records accurately reflect the transaction or condition.

Use this checklist:

• What event occurred?
• Which record should capture it?
• Was the record created timely?
• Is the record accurate and complete?
• Is there supporting documentation?
• Has a principal reviewed it if required by the scenario?
• Does the record agree with related records?
• If not, what reconciliation or correction is needed?

When choices mention destroying, delaying, backdating, omitting, or informally correcting records, they are rarely the most defensible response.

Handling Expense Accrual and Liability Scenarios

Financial responsibility questions often depend on whether liabilities are properly recognized. If the scenario describes unpaid bills, pending settlements, compensation obligations, taxes, rent, professional fees, or other expenses, ask:

• Has the obligation been incurred?
• Is the amount known or reasonably estimable based on the facts?
• Is it already recorded?
• Does failing to record it overstate capital or understate liabilities?
• Does the issue affect a required report or notice?
• Is documentation needed to support the accrual?

Do not focus only on cash paid. A firm’s financial condition depends on obligations as well as cash balances.

Handling Receivable Scenarios

Receivables require careful fact reading because their treatment may depend on the source, age, collectability, security, and documentation.

Ask:

• Who owes the money?
• Why is it owed?
• How old is it?
• Is it secured?
• Is it collectible?
• Is there written support?
• Is it from a customer, broker-dealer, affiliate, employee, vendor, or other party?
• Does the question ask for accounting treatment or regulatory capital treatment?

A receivable may be valid for accounting purposes but still require special treatment for regulatory purposes. Let the question’s wording guide the answer.

Handling Securities Position Scenarios

If the firm has proprietary positions or securities-related balances, identify whether the question is about valuation, haircut treatment, recordkeeping, or settlement.

Ask:

• Is the position firm-owned or customer-related?
• Is it long, short, failed, unsettled, or restricted?
• Is market value provided?
• Is a haircut or deduction supplied or required by the studied rule?
• Does the position create a liability, capital charge, or recordkeeping issue?
• Is the clearing firm involved?

Do not apply a securities product concept just because the product is named. Determine why the product appears in the scenario.

Build a Repeatable Exam-Day Routine

For final review, practice using the same routine on every scenario so it becomes automatic.

The Series 28 Scenario Routine

1. Read the final line first if the stem is long. Know what you are solving for.
2. Read the full scenario once without calculating. Identify role, firm type, and issue.
3. Underline the decision facts mentally. Focus on timing, documentation, authority, and amounts.
4. Classify the question. Financial responsibility, books and records, reporting, clearing relationship, or supervision.
5. Predict the answer direction. Decide what a compliant, well-documented action would look like.
6. Evaluate each answer choice. Eliminate choices that answer the wrong issue or ignore key facts.
7. Select the most defensible answer. Favor accuracy, documentation, proper treatment, and timely escalation.
8. Move on. Do not overwork a question after you have applied a sound process.

Short Practice Prompts for Final Review

Use these prompts with practice questions to strengthen your reasoning.

After each scenario, write one sentence answering each item:

• What is the firm’s role?
• What is the FOP being asked to decide?
• Which facts affect the answer?
• Which facts are background only?
• What record, report, calculation, or control is involved?
• What documentation supports the action?
• What would make the answer defensible to a reviewer?
• Why are the other choices less suitable?

This exercise is slower at first, but it builds the habits needed for faster exam-day decisions.

A Compact Checklist Before You Answer

Before selecting an answer on a Series 28 scenario, ask:

• Did I identify the actual question?
• Did I confirm the firm is acting as an introducing broker-dealer?
• Did I separate customer, firm, and clearing-firm responsibilities?
• Did I classify the issue correctly?
• Did I consider documentation and authority?
• Did I check whether the item affects capital, records, reports, or supervision?
• Did I avoid answering based only on a familiar term?
• Did I choose the answer that best fits all the facts?

If the answer is “no” to any of these, reread the stem before committing.

Practical Next Step

For final review, combine scenario practice with targeted topic drills. Work a set of Series 28 practice questions by category, such as financial responsibility, books and records, reporting, and operational controls. Then take a timed mock exam and review every missed scenario by identifying the role, decision point, relevant facts, and reason the credited answer was the most defensible choice.
