Regulation S-X governs the form and content of financial statements, schedules, acquired-business statements, and pro forma information in covered SEC filings.
Regulation S-X is the SEC framework governing the form and content of financial statements and related financial information in covered registration statements, periodic reports, and other filings. It addresses statement periods, presentation, accountant requirements, schedules, acquired-business financial statements, and pro forma information.
Regulation S-X is organized into articles and rules. Common research areas include:
| Area | General purpose |
|---|---|
| Article 1 | Definitions and general provisions |
| Article 2 | Qualifications and reports of accountants |
| Article 3 | General financial-statement requirements, including certain other entities |
| Article 4 | Rules of general application |
| Articles 5 to 7 | Requirements and formats for specified types of registrants |
| Article 8 | Scaled financial-statement requirements for smaller reporting companies |
| Article 11 | Pro forma financial information |
| Article 12 | Financial-statement schedules |
Specific rules within these articles matter more than the summary label. For example, Rule 3-05 addresses financial statements of businesses acquired or to be acquired, while Article 11 addresses pro forma financial information for specified transactions.
Assume a public company agrees to acquire a private operating business for $180 million. The issuer plans to finance the transaction with $120 million of new debt and $60 million of cash.
The filing team must determine, based on the applicable tests, form, timing, and registrant status, whether the filing requires:
An illustrative pro forma balance-sheet adjustment could show:
| Simplified adjustment | Amount |
|---|---|
| Cash used | $(60 million) |
| New debt | $120 million |
| Purchase consideration | $180 million |
This table does not determine the acquisition accounting or required SEC presentation. Identifiable assets, liabilities, deferred taxes, transaction costs, financing fees, and goodwill would require separate analysis. The purpose of the example is to show why an analyst must distinguish the target’s historical statements from transaction-adjusted pro forma information.
| Framework | Main role |
|---|---|
| Regulation S-X | Form and content of financial statements and related financial information in covered SEC filings |
| Regulation S-K | Integrated business, risk, MD&A, governance, compensation, transaction, and exhibit disclosure |
| SEC form | Specifies the filing vehicle and points to applicable requirements |
| U.S. GAAP | Governs recognition, measurement, presentation, and disclosure for domestic-issuer financial statements |
| PCAOB standards | Govern covered public-company audit and related professional requirements |
S-X and U.S. GAAP overlap in presentation and disclosure but serve different legal and reporting functions. The form instructions, S-X rules, accounting standards, and auditor requirements must be read together.
