DPP control map

Control areaWhat the principal should ask
offering structureWhat type of DPP, offering method, syndication arrangement, and sponsor/dealer-manager relationship is involved?
due diligenceHas the firm reasonably investigated the issuer, program, disclosures, and material assumptions?
compensationAre commissions, wholesaling payments, expenses, and non-cash compensation properly treated and limited?
communicationsAre ads and sales materials balanced, approved, and consistent with offering documents?
suitabilityDoes the recommendation fit the customer’s risk, liquidity, tax, and investment profile?
financial responsibilityAre required reports, books, records, and capital controls preserved and supportable?

Best-answer checklist

  1. Is this an offering-structure issue, a sales-supervision issue, or a financial-responsibility issue?
  2. What makes this fact pattern DPP-specific?
  3. What principal control should exist? due diligence, compensation review, communication approval, suitability review, or financial-control evidence.
  4. What is the highest-risk failure mode? misleading communication, weak due diligence, unsuitable recommendation, compensation breach, or financial-control weakness.
  5. What record or review step proves the principal acted properly?

Common traps

  • treating Series 39 like generic principal supervision instead of DPP-specific supervision
  • focusing on the product but missing the compensation or due-diligence issue
  • overfocusing on sales practice while neglecting the offering-structure block
  • leaving the financial-responsibility block until the end

Final pressure checklist

  • identify the DPP issue before the general supervision issue
  • ask what principal review or restriction should exist
  • favor the balanced and documented answer over the commercially attractive one
  • keep offering structure, communications, and suitability connected
  • do not let generic principal instinct erase DPP-specific compensation and due-diligence rules
