9 — Compliance & Regulatory Guidance
prospective
Registered investment advisers must keep Form ADV current through two amendment mechanisms:
Annual updating amendment — Must be filed within 90 days of the adviser's fiscal year end (Rule 204-1 under the Investment Advisers Act of 1940). The annual amendment requires the adviser to review and update all items on Form ADV Parts 1, 2A, and 2B. The adviser must also deliver or offer to deliver the updated brochure (Part 2A) to existing clients within 120 days of fiscal year end, along with a summary of material changes.
Other-than-annual amendments (interim/prompt amendments) — Certain items on Form ADV must be amended promptly when information becomes inaccurate. "Promptly" is generally interpreted as within 30 days of the event, though some changes require faster action. Items requiring prompt amendment include:
Items that may wait for the annual amendment — Statistical information (AUM, number of clients), non-material updates to biographical information, and administrative details that do not affect client decision-making.
Filing via IARD — All Form ADV amendments are filed electronically through the Investment Adviser Registration Depository (IARD) system. Filing fees apply. State notice filings are typically triggered automatically upon SEC filing for advisers relying on SEC registration.
State notice filings — SEC-registered advisers operating in multiple states must make notice filings with each state in which they have a place of business or meet the de minimis threshold. IARD facilitates most state notice filings alongside the SEC filing.
Form ADV-W (Withdrawal) — An adviser withdrawing from SEC registration files Form ADV-W via IARD. Partial withdrawal (from specific states) or full withdrawal from SEC registration. A withdrawal filing becomes effective 60 days after filing unless the SEC institutes proceedings. Firms must maintain books and records for the applicable retention periods after withdrawal.
SEC Form PF, required under Section 204(b) of the Advisers Act and Rule 204(b)-1, applies to SEC-registered investment advisers that manage one or more private funds.
Filing thresholds and frequency:
Content of Form PF filings: AUM and NAV for each reported fund; borrowings and leverage (gross and net); investor concentration (largest investors as a percentage of NAV); asset class exposure and geographic breakdown; counterparty credit exposure (top counterparties); trading and clearing practices (exchange-traded vs OTC); liquidity of portfolio positions; side pocket and gate usage; performance data; investment strategy classification; use of high-frequency trading strategies.
2023 Amendments — Current Reporting (effective 2024): The SEC adopted amendments to Form PF requiring current reporting of certain triggering events:
Filing is through the SEC's Private Fund Reporting Depository (PFRD) on EDGAR.
SEC Rule 13f-1 under Section 13(f) of the Securities Exchange Act of 1934 requires institutional investment managers exercising investment discretion over $100 million or more in 13(f) securities to file Form 13F quarterly.
Who must file: Any "institutional investment manager" — a broad category that includes investment advisers, banks, insurance companies, broker-dealers, pension funds, and corporations — that exercises investment discretion over the threshold amount. The threshold is measured as of the last trading day of any month in the calendar year. Once crossed, the manager must file for every quarter of that calendar year and the following calendar year.
What to report: Long positions in 13(f) securities as of the last day of the calendar quarter. 13(f) securities include: exchange-listed equities and equity-linked securities (common stock, preferred stock, warrants, convertible securities), shares of closed-end funds, certain exchange-traded options (puts and calls), and shares of ETFs. The official list of 13(f) securities is published quarterly by the SEC.
Required data elements: CUSIP number, issuer name, class title (e.g., "COM" for common stock), market value (rounded to the nearest thousand dollars), number of shares or principal amount, investment discretion type (sole, shared, or none), voting authority (sole, shared, or none), and the number of shares for each voting authority type.
Filing deadline: Within 45 days of calendar quarter end (filed on SEC EDGAR).
Confidential treatment requests: Managers may request confidential treatment under Rule 24b-2 for positions where public disclosure would reveal a trading strategy still being implemented (e.g., ongoing accumulation or disposition). The SEC grants confidential treatment on a case-by-case basis and requires a showing that disclosure would likely cause competitive harm. Historically, the SEC has narrowed the grounds for confidential treatment.
Common errors and consequences: Late filings result in public notice and may trigger SEC enforcement. Reporting errors in CUSIPs, share counts, or market values can mislead market participants. Firms must verify 13F data against custodian records and ensure consistent treatment of jointly managed accounts. The SEC has brought enforcement actions for material misstatements on Form 13F.
SEC Rule 13h-1 under Section 13(h) of the Exchange Act requires "large traders" to identify themselves to the SEC and receive a Large Trader Identification Number (LTID).
Large trader thresholds: A person (including a firm) is a "large trader" if their transactions in NMS securities equal or exceed:
Transactions across all accounts over which the person exercises investment discretion are aggregated. The thresholds apply to both purchases and sales.
Form 13H filing requirements:
LTID assignment and use: Upon filing, the SEC assigns an LTID. The large trader must provide the LTID to each broker-dealer through which it trades. The LTID is attached to the large trader's accounts at each broker-dealer.
Broker-dealer obligations: Broker-dealers carrying accounts for large traders must: (a) maintain records of transactions effected through large trader accounts, (b) report large trader transaction data to the SEC upon request (historically via Electronic Blue Sheets, now increasingly through CAT), and (c) monitor for customers who may meet the large trader definition but have not self-identified.
The Financial and Operational Combined Uniform Single (FOCUS) report is the primary financial reporting form for broker-dealers, required under SEC Rule 17a-5 and filed through FINRA's systems.
Filing frequency and form versions:
Content of FOCUS reports:
Filing and regulatory oversight: FOCUS reports are filed with FINRA as the firm's designated examining authority (DEA). FINRA reviews filings for accuracy, timeliness, and compliance with net capital and customer protection rules. FOCUS data is shared with the SEC. Late filing, inaccurate filings, or filings showing net capital deficiencies trigger heightened regulatory scrutiny.
Consequences of late or deficient filings: FINRA may impose fines, censure, or suspend a firm for persistent late filings. A FOCUS report showing a net capital deficiency triggers immediate obligations under SEC Rule 17a-11 (discussed in the worked examples below).
SEC Rule 17a-25 requires broker-dealers to submit, upon SEC request, standardized electronic trading records for specified securities and time periods.
When requested: Blue sheet requests typically arise during SEC investigations into potential insider trading, market manipulation, or other trading violations. The SEC's Division of Enforcement issues blue sheet requests identifying the securities, time period, and type of trading data required.
Data elements: Customer identity (name, address, SSN/TIN), account number, transaction date and time, security identifier (CUSIP/symbol), buy/sell/short sale indicator, quantity, price, executing broker, clearing broker, and the capacity in which the firm acted (principal or agent).
Timeliness: Broker-dealers must respond within the timeframe specified in the request, typically 10 business days. Firms should have systems capable of extracting and formatting blue sheet data promptly.
Relationship to CAT: The Consolidated Audit Trail (CAT) has largely superseded blue sheets for routine regulatory surveillance purposes. FINRA and the SEC can now access much of the same information through CAT data. However, the SEC continues to use blue sheet requests for specific enforcement investigations, particularly when CAT data is incomplete or when historical data predating CAT implementation is needed. The SEC has announced plans to retire the Electronic Blue Sheet system as CAT reaches full maturity, but as of the current date, both systems remain in use.
Enforcement for non-compliance: Failure to respond accurately or timely to blue sheet requests can result in SEC enforcement action. The SEC has brought cases against firms for submitting inaccurate blue sheet data, including incorrect customer identification or missing transactions.
SEC Rule 613 mandated the creation of the Consolidated Audit Trail, the most comprehensive order tracking system in U.S. securities markets. The CAT Plan was adopted in 2016, and reporting obligations have been phased in for equities and options.
Who must report: All broker-dealers that are members of a national securities exchange or FINRA ("Industry Members") and all national securities exchanges ("Plan Participants") must report to CAT. This includes introducing brokers, clearing firms, market makers, ATSs, and exchange members.
What is reported: CAT captures every reportable event in the lifecycle of an order for NMS equities and listed options:
Customer and Account Identifying Information (CAIS): Industry Members must submit CAIS data linking each account to its customer(s). CAIS includes: customer name, address, date of birth (for individuals), SSN/EIN, and account information. CAIS is submitted through a separate reporting channel and must be kept current.
Clock synchronization requirements: Accurate timestamps are essential for order lifecycle tracking. SEC Rule 613 and the CAT NMS Plan require:
Error correction obligations: CAT reporting firms must monitor their submissions for errors flagged by the CAT system. The CAT system validates submissions and generates error reports. Firms must:
Implementation timeline: Large Industry Members began reporting equities in April 2020 and options in 2022. Small Industry Members followed shortly thereafter. The full lifecycle reporting, including allocations and CAIS data, has been phased in incrementally. Firms should consult the FINRA CAT website and the CAT NMS Plan Processor (FINRA CAT, LLC) for current reporting specifications and implementation deadlines.
Retirement of OATS: FINRA's Order Audit Trail System (OATS), which previously served as the primary order tracking system for FINRA member firms, was retired on September 1, 2020, following the implementation of CAT reporting for equities.
While the substantive AML compliance framework is covered in the anti-money-laundering skill, the reporting mechanics are a regulatory reporting obligation:
FinCEN BSA E-Filing System — SARs (FinCEN Form 111) and CTRs (FinCEN Form 112) are filed electronically through FinCEN's BSA E-Filing System. Firms must register for BSA E-Filing, designate authorized users, and maintain access credentials securely.
SAR filing deadlines:
CTR filing deadlines:
SAR confidentiality — 31 U.S.C. Section 5318(g)(2) prohibits any financial institution, or any officer, director, employee, or agent thereof, from disclosing to the person involved in the transaction (or any other person) that a SAR has been or will be filed. This tipping-off prohibition extends to responses to subpoenas, discovery requests, or other legal process — SARs themselves are not producible, although the underlying facts are not privileged.
Recordkeeping for filed reports:
Beyond FOCUS reports and CAT, FINRA member firms have several additional reporting obligations:
Short interest reporting (FINRA Rule 4560) — Member firms must report short positions in all equity securities (customer and proprietary) as of settlement on the designated reporting date, which occurs twice monthly (approximately the 15th and last business day of each month). Reports are due to FINRA by 6:00 p.m. ET on the second business day after the reporting settlement date. FINRA publishes aggregate short interest data, and individual firm reports are used for regulatory surveillance.
TRACE (Trade Reporting and Compliance Engine) — FINRA-operated system for reporting OTC transactions in eligible fixed-income securities, including corporate bonds, agency debentures, asset-backed securities, and certain other debt instruments. Reporting is required within 15 minutes of execution for most transactions (FINRA Rules 6710-6770). TRACE-eligible securities have expanded over time to include Treasury securities (effective 2020 under FINRA Rule 6730). Late TRACE reports result in regulatory action.
Trade reporting to FINRA-operated facilities — For OTC equity transactions, member firms must report trades to the appropriate FINRA facility:
Trade reports must be submitted within 10 seconds of execution during market hours.
Regulatory filings and notifications — FINRA members must promptly notify FINRA of certain events under FINRA Rule 4530, including: violations of securities laws, written customer complaints, regulatory actions by other agencies, criminal charges against associated persons, and civil litigation related to the firm's investment banking or securities business. Annual statistical reports of customer complaints are also required.

Scenario: An investment advisory firm has been state-registered for three years, managing $120 million in a mix of separate accounts and a single private fund (a hedge fund with $50 million in AUM). In Q2 2025, the firm's total AUM crosses $150 million, and its private fund AUM remains at $50 million. The firm files for SEC registration, which becomes effective in September 2025. The firm has a December 31 fiscal year end. Compliance Issues:
Scenario: A carrying broker-dealer files its monthly FOCUS Part IIA report for January 2026. The net capital computation shows that the firm's net capital has fallen below its minimum required net capital by $1.2 million, driven by unexpected trading losses in a proprietary account and an increase in customer debit balances that raised the firm's required net capital under the alternative method (SEC Rule 15c3-1(a)(1)(ii)). The firm's minimum requirement is $250,000, but its required net capital under the alternative method is $4.5 million, and actual net capital is $3.3 million. Compliance Issues:
Scenario: A mid-sized broker-dealer receives a blue sheet request from the SEC's Division of Enforcement seeking transaction data for a particular security over a 90-day period, related to a suspected insider trading investigation. While compiling the blue sheet response, the firm's compliance team discovers that its CAT reporting system has been systematically misidentifying customers for approximately 6 months due to a software mapping error. The error caused roughly 15,000 order events to be submitted to CAT with incorrect Customer Account IDs, linking orders to the wrong customer accounts in CAIS. The blue sheet data, compiled independently from the firm's order management system, is accurate. Compliance Issues:
