Series 28 Customer Protection, Funding and Cash Management Guide
Learn how Series 28 tests Rule 15c3-3 exemptive status, carrying-agreement allocation, transmission of customer assets, margin controls, checks and securities processing, reconciliations, subordinations, and funding-impairment judgment.
This closing Series 28 function is where candidates prove they understand the introducing-firm perimeter. The exam wants to know which customer-protection duties still matter, which responsibilities sit with the clearing firm under the carrying agreement, how margin and cash-management workflow should be supervised, and when subordinations or funding impairment change the firm’s options.
The strongest answers usually begin by asking whether the issue belongs to the introducing firm, the clearing firm, or both, and then whether the event affects customer-protection status, margin control, or funding stability.

Weight

Main skill
identify how the introducing-firm perimeter changes the customer-protection or funding answer
Typical trap
importing full carrying-firm obligations without checking the exemption or carrying-agreement allocation
Strongest first instinct
ask what the introducing firm still owes, what the clearing firm handles, and whether funding or margin conditions change the control response
Series 28 is testing whether you can hold the customer-protection and funding line without forgetting the firm’s limited scope. Strong answers distinguish what the introducing firm must still monitor, transmit, document, and escalate from what the clearing firm directly holds or processes.
Section-by-section lesson
Exemptive status under Rule 15c3-3 and carrying agreement allocation
This is the starting point. If you miss the exemptive status or carrying-agreement allocation, many later answers will drift into the wrong firm’s responsibilities. The FINOP should always ask whether the duty sits with the introducing firm, the clearing firm, or is shared through control and oversight.
Transmission of customer assets, underwriting funds, privacy, and confidential information
Even where the firm relies on an exemption, handling customer-related assets and information still creates process obligations. The exam wants the FINOP to know that prompt transmission, privacy, and information control remain active concerns.
Margin requirements, calls, excesses, deficits, and maintenance of credit
Margin questions test workflow discipline. The candidate should identify deficits, excesses, calls, and maintenance consequences without losing sight of the introducing-firm boundary.
Processing customer checks and securities, day trading, corporate actions, and reorganizations
These questions focus on how customer events are processed and followed through. The right answer usually connects timing, documentation, and responsibility allocation.
Repurchases, reverse repurchases, withdrawal restrictions, concentration of margin debits, and liquidation decisions
This section tests funding judgment. The FINOP should ask whether the firm’s cash or credit position changes what is safe, allowed, or reportable.
Processing account reconciliations, money and control location accounts, and introducing vs clearing responsibilities
This section ties customer protection back to operational evidence. The exam rewards candidates who can say which party does what and how the introducing firm verifies that the arrangement is still functioning properly.
Subordinations, secured demand notes, funding impairment, and notice or approval implications
Funding-support questions are really stress questions. The strongest answer usually asks whether the support is still valid, what notice or approval is needed, and whether the firm’s financial condition is weakening in a way that changes the next step.

If the vignette shows…
Stronger implication
confusion about who holds or processes customer assets
carrying-agreement allocation issue
customer funds or checks handled loosely
transmission and control concern
margin deficit or maintenance problem
credit and margin workflow issue
cash-support arrangement under stress
funding impairment or notice issue
customer-protection duty described too broadly
introducing-firm perimeter check required
What stronger answers usually do
confirm the introducing-vs-clearing responsibility split first
treat prompt transmission and confidentiality as active duties
ask what margin, credit, or funding event changes the control response
recognize when subordinations or funding support create notice, approval, or impairment issues
Sample Exam Question
A FINOP treats a customer-protection question as if the introducing firm directly carried the account and held the customer funds, even though the firm operates under a clearing agreement and relies on the relevant exemption. What is the strongest conclusion?
A. The approach is acceptable because all broker-dealers owe identical customer-protection duties
B. The approach is weak because the introducing-firm and clearing-firm allocation changes the correct analysis
C. The issue only matters for margin accounts
D. Customer-protection exemptions eliminate the need for any customer-related controls
Answer: B
Series 28 often tests perimeter discipline. The introducing-firm boundary changes the answer, but it does not eliminate customer-related control obligations.
Common traps
importing full carrying-firm obligations automatically
thinking exemption means no control duty
losing the margin and funding workflow inside the perimeter question
missing notice and approval implications for support arrangements
Key takeaways
This topic is about customer-protection judgment inside a limited-scope firm.
Strong answers distinguish introducing-firm duties from clearing-firm duties without treating the introducing firm as passive.
Margin, cash-management, and funding-support events still require documented control and escalation.
