Introduction

Welcome to Financial Responsibility and Funding: the requirements that govern whether a member firm has enough capital to operate, whether customer assets are properly segregated, and what happens when the firm's financial condition deteriorates.

The unit walks through:

  • Capital and reserves: The net-capital rule, the customer protection rule, and the FOCUS reporting regime
  • Early-warning regime: SEC notification triggers and the FINRA early-warning layer
  • Margin framework: Reg T plus FINRA's margin requirements, daily-margin record, margin-extension procedure, and CDS-margin requirement
  • Customer-asset rules: Carrying-agreement requirement, customer-securities-lending requirement, hypothecation rules, and the 30-day distribution credit restriction
  • Disclosures and reporting: Credit-disclosure requirement, clearing-firm reporting requirement, and short-interest reporting requirement
  • Insurance and protection: Fidelity-bond requirement, lost/stolen securities rule, and the SIPC / SIPA customer-protection regime
  • Cross-cutting infrastructure: Sarbanes-Oxley internal-controls layer, foreign-member registration requirement, and trade-clearance requirements through ORF, Nasdaq TRF, and FINRA / NYSE TRF

Exam Weight: Part of 30% (~45 questions across Function 2)

What You'll Learn

In this unit, you'll cover:

  • Net Capital Requirements: The Basic Method (6 2/3% of aggregate indebtedness) and the Alternative Method (2% of aggregate debit items), the dollar minimums by firm category ($250,000 carrying / $50,000 introducing / $5,000 introducing-no-funds / $1,500,000 prime broker / $1,000,000 executing broker / $100,000 market maker / $25,000 mutual fund retailer), the net-capital computation framework, and the subordinated-loan agreement requirements
  • Customer Protection: The two pillars (possession or control of fully paid securities, and the Special Reserve Bank Account), the 140% excess margin definition, the customer Reserve Formula, the weekly computation and the deposit due on the second following business day, the $500 million average-credit threshold for daily computation, and the separate PAB Reserve computation
  • Free Credit Balances: The quarterly written statement telling customers the amount of their free credit balances and that the funds are payable on demand
  • FOCUS Reports: Form X-17A-5 Part I (monthly, carrying / clearing firms, within 10 business days), Part II (quarterly, carrying / clearing firms, within 17 business days), Part IIA (quarterly, non-carrying firms), Part III (annual audit, 60 calendar days after fiscal year end), and the PCAOB-registered-auditor requirement
  • Early-Warning Notification Provisions: Same-day notice for net-capital-below-minimum, insolvency, or a books-and-records failure, and 24-hour notice for the 120% trigger, the aggregate-indebtedness ratio above 12:1 / 1,200%, and the material-inadequacy trigger
  • FINRA Early-Warning Notification and Curtailment: The 150% trigger, the 15-business-day expansion restriction, and FINRA's curtailment authority
  • FINRA Margin Requirements: Reg T 50% initial margin, FINRA 25% maintenance long / 30% maintenance short, the intraday-margin-deficit framework that replaced the repealed Pattern Day Trader regime (the 5-business-day cure period and 90-day restriction for a customer who keeps missing the deadline), and portfolio margin (≥$100,000 equity)
  • Daily-Margin Record, Margin-Extension Procedure, and CDS Margin: The daily margin record, the Reg T / customer-protection extension-of-time process, and the credit default swap margin framework
  • Carrying Agreements: The written agreement, the function-allocation list (with safeguarding always allocated to the carrying firm), the customer-disclosure document delivered at account opening, and the 10-business-day advance FINRA notice for a new introducing firm (with CRD number)
  • Customer Securities Lending: Margin-securities lending under the customer's signed margin agreement, fully-paid lending requiring 30-day advance FINRA notice plus appropriateness review plus written SIPA-doesn't-cover disclosure, and the daily mark-to-market collateral requirement
  • Hypothecation of Customer Securities: The three prohibitions (no customer-to-customer commingling without each customer's consent, no customer-to-firm commingling under any circumstance, no over-pledging above the customer's debt) and the pledgee-notice requirement
  • New-Issue Credit Restriction and Related Exemptions: The 30-day prohibition on extending credit on a security the firm helped distribute, the direct participation program (DPP) exemption, the investment-company-share margin-collateral exemption, the credit-extension disclosure rule, and the pro forma rule
  • Federal Reserve Regulation T: The 50% initial margin, the S+2 Reg T payment date, the 90-day cash-account freeze for free-riding (selling before full payment), and the cancellation/liquidation of unpaid purchases
  • Margin Credit Disclosures: The account-opening written statement (interest rates, calculation method, conditions, daily debit balance method) and the quarterly statement plus the advance notice of any change
  • FINRA Clearing-Firm Reporting: The clearing-firm reporting rule's electronic customer account information reporting requirement for clearing firms (introducing firms do not report), and why FINRA discontinued actually collecting this data (INSITE) effective November 30, 2023, even though the reporting requirement remains in force
  • Short-Interest Reporting: The mid-month and end-of-month reporting cadence and the 6:00 p.m. ET / 2-business-day filing deadline
  • Fidelity Bonds: The minimum coverage tiers (greater of 120% of net capital requirement or $100,000 for firms with NCR < $250,000; tabular for $250,000+), the per-loss / no-aggregate-limit requirement for every member's bond (all net-capital tiers), the 25% deductible cap (with anything over 10% deducted from net worth), and the annual recalibration based on highest NCR in prior 12 months
  • Lost / Stolen Securities: Reporting to the Securities Information Center (SIC) on Form X-17F-1A, concurrent transfer-agent and (if criminal) FBI notice, and the $10,000 inquiry threshold (query the SIC within 5 business days of receipt, before reselling or pledging)
  • SIPC / SIPA: Mandatory SIPC membership, $500,000 total per separate customer per separate capacity (with $250,000 cash sub-limit), what SIPC does and does not cover (no market losses), the trustee-liquidation process, SIPC advances, prohibited acts, and excess SIPC private insurance
  • Sarbanes-Oxley Internal Controls: Internal Control over Financial Reporting (ICFR) and the PCAOB inspection regime
  • Foreign-Member Registration and Exempted Securities: the foreign-member rule's four duties (English/U.S.-dollar reports, examination-cost reimbursement, an English-speaking examination liaison, and a U.S. clearing channel), and the exempted-securities scope
  • Clearance and Settlement: Trade-clearance obligations through registered clearing agencies (typically NSCC) for ORF, Nasdaq TRF, and FINRA / NYSE TRF reported transactions

Why This Matters

The Series 24 exam tests three principal-level themes from this material:

  • Whether the firm understands that financial responsibility is a system of overlapping floors and triggers, not a single number. The net-capital rule sets a dollar minimum and a ratio. The customer protection rule sets a custody and reserve discipline. The SEC early-warning notification regime layers on top. The FINRA early-warning notification layers an even earlier warning on top of that
  • A principal who memorizes the 100% / 120% / 150% ladder without understanding the underlying mechanics will miss questions that test the interaction (e.g., a firm that satisfies the dollar minimum but fails the 1,200% AI ratio still owes a 24-hour notice)
  • Whether the firm honors the customer-asset-segregation discipline at every margin and lending touchpoint. The customer protection rule establishes the framework. The customer-securities-lending requirement layers customer-consent requirements on top of any lending. The hypothecation rules cap pledging at the customer's debt and forbid customer-firm commingling
  • The new-issue credit restriction prevents the firm from financing customer purchases of a security it just helped distribute. SIPC stands behind the whole structure if the firm fails. A break in any layer is a separate violation
  • Whether the firm has structural controls in place for the entry, ongoing, and exit financial-responsibility events. Entry: net capital qualification, subordinated-loan approval, fidelity bond, SIPC membership, PCAOB-registered auditor engagement. Ongoing: FOCUS filings, weekly / daily reserve computations, daily margin records, short-interest reports, customer account information reports
  • Exit: SEC early-warning notifications, business-expansion restrictions, FINRA-imposed curtailment, ultimately SIPC liquidation. The exam draws supervisory questions across all three phases

Each layer is independently testable:

  • A firm that satisfies its dollar minimum but allows a prepaid expense to be treated as an allowable asset has a net-capital rule violation
  • A firm that holds customer free credit balances without quarterly free-credit-balance disclosures has a customer-protection violation independent of whether the reserve formula is met
  • A firm that loans customer securities without the appropriateness analysis required by the customer-securities-lending requirement has a separate violation even if SIPC ultimately covers the customer

The exam draws supervisory questions from each layer of the financial-responsibility infrastructure, not just from the headline ratios.

Let's start with the net-capital rule, the foundation of every other requirement in this unit.
