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

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 / $1,000,000 prime 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 Tuesday deposit cycle, the $500 million average-credit threshold for daily computation effective June 30, 2026, and the separate PAB Reserve computation
  • Free Credit Balances: The quarterly written notice that customer free credit balances are payable on demand and may be used in the firm's business
  • FOCUS Reports: Form X-17A-5 Part II (monthly, carrying / clearing firms), Part IIA (quarterly, non-carrying firms), Part III (annual audit, 60 calendar days after fiscal year end), the 17-business-day deadline for FOCUS II / IIA, and the PCAOB-registered-auditor requirement
  • Early-Warning Notification Provisions: Same-day notice for net-capital-below-minimum or insolvency, 24-hour notice for the 120% trigger and the aggregate-indebtedness ratio above 12:1 / 1,200%, and the books-and-records / material-inadequacy triggers
  • 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 Pattern Day Trader ($25,000 minimum equity), the day-trading-margin-call 5-business-day cure period and 90-day restriction, portfolio margin (≥$100,000 equity), and the April 2026 intraday-margin amendments
  • 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, the 10-business-day advance FINRA notice for a new introducing firm (with CRD number), and the annual safekeeping-institution notice
  • 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 DPP exemption, the investment-company-share margin-collateral exemption, the disclosure-when-extending-credit rule, and the pro-forma-balance-sheet anti-fraud rule
  • Federal Reserve Regulation T: The 50% initial margin, the S+1 Reg T payment date, the 90-day cash-account freeze for unpaid purchases, and the free-riding prohibition
  • 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: Electronic customer account information reporting by clearing firms (introducing firms do not report)
  • 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 $250,000+ firms, 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 before accepting a certificate
  • 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: Foreign-member registration via U.S. process agent and U.S. recordkeeping, 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 an asset-segregation 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.
