High-yield Series 39 cheat sheet for the FINRA DPP Principal exam: exam facts, DPP offering controls, sales supervision, due diligence, compensation, and financial-responsibility traps.
Series 39 is “DPP principal control.” Most questions ask what the principal should supervise, approve, restrict, disclose, document, or escalate inside a direct participation programs business line.
Quick links:
| Route | Use when… |
|---|---|
| Series 39 | principal supervision is concentrated in direct participation programs |
| Series 22 | the role is DPP representative activity rather than principal supervision |
| Series 24 | the role is broader general securities principal supervision |
| Control area | What the principal should ask |
|---|---|
| offering structure | What type of DPP, offering method, syndication arrangement, and sponsor/dealer-manager relationship is involved? |
| due diligence | Has the firm reasonably investigated the issuer, program, disclosures, and material assumptions? |
| compensation | Are commissions, wholesaling payments, expenses, and non-cash compensation properly treated and limited? |
| communications | Are ads and sales materials balanced, approved, and consistent with offering documents? |
| suitability | Does the recommendation fit the customer’s risk, liquidity, tax, and investment profile? |
| financial responsibility | Are required reports, books, records, and capital controls preserved and supportable? |
| If the question feels like… | First bucket | Strongest first instinct |
|---|---|---|
| product structure, offering method, or compensation setup | offering structure | identify the DPP feature before judging the conduct |
| ad, rep activity, or customer recommendation | sales supervision | ask what the principal should have reviewed or restricted |
| capital, reporting, or financial controls | financial responsibility | identify the control evidence and firm obligation |
| If the stem shows… | Think first about… | Usually strongest next move |
|---|---|---|
| compensation or offering arrangement that feels aggressive | DPP structure and due diligence | verify limits, review documentation, and escalate if needed |
| promotional language that sounds too clean | communications supervision | revise, reapprove, and restore balance |
| retirement or suitability pressure | customer supervision | verify fit, disclosure, and recommendation basis |
| funding or financial-control weakness | financial responsibility | choose the conservative documented response |
