Question 1

What is Regulation S-X (17 CFR part 210)?

Accepted Answer

Regulation S-X is the set of SEC accounting rules, codified at 17 CFR part 210, that prescribes the form and content of — and the requirements for — the financial statements and financial statement schedules filed with the Commission. Its companion, Regulation S-K (17 CFR part 229), governs the non-financial narrative disclosures; Regulation S-X governs the financial statements themselves. Rule 1-01(a) states that part 210, together with the Financial Reporting Releases (part 211), sets forth the form and content of and requirements for financial statements required to be filed as part of registration statements and reports under the federal securities laws. Regulation S-X does not itself set U.S. accounting principles — those come from U.S. generally accepted accounting principles (GAAP) — but it dictates how financial statements are presented to the SEC: which periods they must cover, when they must be audited, and what schedules and additional disclosures accompany them.

Question 2

What is the statutory authority for Regulation S-X?

Accepted Answer

Regulation S-X is issued under a broad grant of authority spanning the federal securities laws. Its authority citation lists provisions of the Securities Act of 1933, the Securities Exchange Act of 1934, the Investment Company Act of 1940, the Investment Advisers Act of 1940, the Sarbanes-Oxley Act of 2002, and the JOBS Act of 2012. The authority note for 17 CFR part 210 cites, among many provisions, 15 U.S.C. 77f, 77g, 77h, 77j and 77s (Securities Act of 1933), 78c, 78j-1, 78l, 78m, 78n and 78w (Securities Exchange Act of 1934), 80a-8, 80a-29 and 80a-30 (Investment Company Act of 1940), 80b-3 and 80b-11 (Investment Advisers Act of 1940), and 15 U.S.C. 7202 and 7262 (Sarbanes-Oxley Act of 2002), together with section 102(c) of the JOBS Act, Public Law 112-106, 126 Stat. 310 (2012). Section 78j-1 (Exchange Act Section 10A) and the Sarbanes-Oxley citations underlie the auditor-independence, audit-record-retention, and audit-committee-communication rules in Article 2.

Question 3

Which SEC filings does Regulation S-X govern?

Accepted Answer

Rule 1-01 makes Regulation S-X apply to the financial statements filed as part of three broad categories of filings: registration statements under the Securities Act of 1933; registration statements, periodic and current reports, and proxy and information statements under the Securities Exchange Act of 1934; and registration statements and shareholder reports under the Investment Company Act of 1940 — in each case except as a specific form provides otherwise. Rule 1-01(a) lists Securities Act registration statements (part 239), Exchange Act registration statements under Section 12 and reports under Sections 13 and 15(d) (part 249) and proxy and information statements under Section 14, and Investment Company Act registration statements and shareholder reports (part 274). Because a Form S-1 IPO prospectus and the Form 10-K, Form 10-Q, and Form 8-A that follow all draw their financial statements from Regulation S-X, the same presentation rules govern a company's offering document and its later Exchange Act reports.

Question 4

How is Regulation S-X organized, and what does Article 1 cover?

Accepted Answer

Regulation S-X is divided into numbered Articles, each a subject grouping of rules, and within each Article the individual rules are cited in the form 'Rule 3-01' (which is § 210.3-01). Article 1 states how the regulation applies (Rule 1-01) and defines the terms used throughout it (Rule 1-02). Rule 1-02 supplies the definitions that recur across the regulation — including 'affiliate,' 'material,' 'audit,' 'control,' and 'significant subsidiary,' the last of which sets the quantitative investment, asset, and income tests that determine when separate or additional financial statements of an acquired business or an unconsolidated subsidiary must be filed. The Articles run from Article 1 through Article 12, with lettered Articles 3A and 6A and later-added Articles 13 and 15; the table below maps each one to its sections and subject.

Question 5

What is Article 2 — Qualifications and Reports of Accountants?

Accepted Answer

Article 2 (Rules 2-01 through 2-07) covers the qualifications and reports of accountants. Rule 2-01 sets the auditor-independence requirements an accountant must meet to be qualified to audit an SEC filer; Rule 2-02 sets the requirements for the accountant's report; and Rules 2-06 and 2-07 address retention of audit records and communication with audit committees. Rule 2-02 requires that the accountant's report be dated, be signed manually, indicate the city and State where issued, identify the financial statements covered, state the professional standards under which the audit was conducted, and express an opinion on the financial statements and on the consistency of the accounting principles applied. The detailed independence standard of Rule 2-01 — the general standard and the specific prohibited relationships and non-audit services — is treated on the IPO Center's IPO Accountant (auditor independence) page; this reference page describes Article 2 as one structural component of Regulation S-X.

Question 6

What does Article 3 (General Instructions) require as to periods?

Accepted Answer

Article 3 (Rules 3-01 through 3-20) is the 'General Instructions as to Financial Statements' — the rules that set which statements to file and the periods they cover. Rule 3-01 requires audited balance sheets as of the end of each of the two most recent fiscal years, and Rule 3-02 requires audited statements of comprehensive income and cash flows for each of the three fiscal years preceding the date of the most recent audited balance sheet. Rule 3-02(a) expressly permits an emerging growth company, in a Securities Act registration statement for the initial public offering of its equity securities, to provide two years of audited income and cash-flow statements instead of three. Article 3 also contains Rule 3-05 (financial statements of businesses acquired or to be acquired), Rule 3-09 (separate statements of certain unconsolidated subsidiaries), and Rule 3-12 (age of financial statements). The applied question of exactly which statements a particular IPO issuer must present is covered on the IPO Financial Statements page; here Article 3 is described as the general-instruction component of the regulation.

Question 7

What is Article 4, and what is its GAAP presumption?

Accepted Answer

Article 4 (Rules 4-01 through 4-10) states the rules of general application that cut across all filers. Rule 4-01 provides that financial statements filed with the Commission that are not prepared in accordance with generally accepted accounting principles will be presumed to be misleading or inaccurate, despite footnote or other disclosures, unless the Commission has otherwise provided. Article 4 also requires that the information furnished be sufficient to make the required statements not misleading (Rule 4-01), permits omission of immaterial items (Rule 4-02), prescribes general notes to the financial statements (Rule 4-08), and sets out the financial accounting and reporting rules for oil and gas producing activities under the successful-efforts and full-cost methods (Rule 4-10). These general rules apply on top of whichever industry Article governs the specific filer.

Question 8

What are the industry-specific Articles (5, 6, 6A, 7, and 9)?

Accepted Answer

Regulation S-X prescribes the detailed line items of the balance sheet, income statement, and required schedules through industry-specific Articles. Article 5 applies to commercial and industrial companies — the default for most operating companies; Article 6 applies to registered investment companies and business development companies; Article 6A to employee stock purchase, savings, and similar plans; Article 7 to insurance companies; and Article 9 to bank holding companies and banks. Rule 5-01 states that Rules 5-01 to 5-04 apply to all persons except registered investment companies (Article 6), employee plans (Article 6A), insurance companies (Article 7), bank holding companies and banks (Article 9), and brokers and dealers filing Form X-17A-5. Within each industry Article, separate rules prescribe the balance sheet captions (for example, Rule 5-02), the statement of comprehensive income captions (Rule 5-03), and which schedules must be filed (Rule 5-04). A filer uses the Article matching its industry to build the face of its financial statements.

Question 9

What is Article 8 — Financial Statements of Smaller Reporting Companies?

Accepted Answer

Article 8 (Rules 8-01 through 8-08) sets scaled financial-statement requirements for smaller reporting companies, as defined in Item 10(f)(1) of Regulation S-K (17 CFR 229.10(f)(1)). A smaller reporting company electing Article 8 files two years of audited balance sheets and two years of audited statements of comprehensive income, cash flows, and changes in stockholders' equity — rather than the three years of income and cash-flow statements Rule 3-02 requires of other issuers. Rule 8-02 requires audited balance sheets as of the end of each of the two most recent fiscal years and audited income, cash-flow, and equity statements for the two fiscal years preceding the date of the most recent audited balance sheet. Rule 8-03 governs interim financial statements, Rules 8-04 and 8-05 govern acquired-business and pro forma information, and Rule 8-08 governs the age of the financial statements. Under Rule 8-01, a smaller reporting company electing Article 8 need not apply the other form-and-content Articles of Regulation S-X except as that rule specifies.

Question 10

What are Articles 10 and 11 — interim and pro forma financial information?

Accepted Answer

Article 10 (Rule 10-01) governs interim financial statements — the condensed, generally unaudited statements included in quarterly reports and in registration statements between audited year-ends. Article 11 (Rules 11-01 through 11-03) governs pro forma financial information, which must be filed when, among other conditions, a significant business acquisition has occurred or is probable, or a significant disposition has occurred. Rule 10-01 provides that interim statements follow the general form and content of the other Articles but may be limited to the major (numbered) captions and may be unaudited. Rule 11-01 lists the conditions that trigger pro forma information, and Rule 11-02 requires that it consist of a pro forma condensed balance sheet, pro forma condensed statements of comprehensive income, and explanatory notes, introduced by a paragraph describing each transaction, the entities involved, the periods presented, and what the presentation shows.

Question 11

What is Article 12, and what are the later Articles 13 and 15?

Accepted Answer

Article 12 (Rules 12-01 through 12-29) prescribes the form and content of the financial statement schedules that the industry Articles require — for example, Schedule II, 'Valuation and Qualifying Accounts,' under Rule 12-09. Two later-added Articles extend the regulation: Article 13 (Rules 13-01 and 13-02) covers financial and non-financial disclosures for guarantors and issuers of guaranteed securities and for affiliates whose securities collateralize a registered security, and Article 15 (Rule 15-01) covers the audit requirements for acquisitions of businesses by a shell company. Rule 12-01 states that Rules 12-01 to 12-29 prescribe the form and content of the schedules required by Rules 5-04, 6-10, 6A-05, and 7-05; the Article then sets out those schedules, including separate schedules for management investment companies, face-amount certificate investment companies, and certain real estate companies. Articles 13 and 15 were added by later SEC amendments — Article 13 by the 2020 amendments on financial disclosures about guarantors and collateral (85 FR 21940, April 20, 2020), which moved the detailed disclosure requirements formerly set out in Rules 3-10 and 3-16 into new Rules 13-01 and 13-02 — reflecting the regulation's growth beyond the original Articles 1 through 12.

Question 12

How does Form S-1 incorporate Regulation S-X?

Accepted Answer

Form S-1 does not restate the financial-statement rules; it incorporates Regulation S-X by reference. Item 11 of Form S-1, 'Information with Respect to the Registrant,' calls in Item 11(e) for financial statements meeting the requirements of Regulation S-X. The periods, audit requirements, interim updating, and schedules for an S-1 issuer therefore come directly from Rules 3-01, 3-02, and 3-12 and the applicable industry Article (or from Article 8 for a smaller reporting company). Item 11(e) of Form S-1 requires financial statements and financial statement schedules meeting the requirements of Regulation S-X, together with the acquired-business statements of Rule 3-05 and the pro forma information of Article 11 (Rules 8-04 and 8-05 for a smaller reporting company). Item 11 also cross-references Regulation S-K for the related narrative — supplementary financial information and Management's Discussion and Analysis (Regulation S-K Item 303). This division is why Regulations S-X and S-K are read together: S-K prescribes the narrative, and S-X prescribes the financial statements that narrative discusses.

Question 13

What is the SEC Financial Reporting Manual, and how does it relate to Regulation S-X?

Accepted Answer

The Financial Reporting Manual (FRM) is a reference maintained by the staff of the SEC's Division of Corporation Finance that explains how the staff interprets and applies Regulation S-X and the related financial-reporting requirements. It is informal staff guidance, not a Commission rule, and it does not carry the force of law. The Division states that the manual was originally prepared as internal guidance for its staff and was posted to the SEC website in 2008 to increase transparency of the staff's informal interpretations, and that because of its informal nature it does not necessarily address all considerations needed to reach an accounting or disclosure conclusion. The Division updates sections of the manual periodically, marking updated sections with a date tag (the most recent updates are dated in 2025). The FRM is a widely used aid for applying Regulation S-X, but the binding requirements are those in 17 CFR part 210 itself.
