Public Company Reporting, Segments & Interim Reporting

Why this topic matters

Public companies report to the Securities and Exchange Commission (SEC) on a regular schedule, and must present segment information (Accounting Standards Codification (ASC) 280) and interim financial statements (ASC 270). Financial Accounting and Reporting (FAR) tests filing deadlines and form types, the quantitative thresholds for reportable segments, and the "integral view" of interim reporting.

SEC reporting

Regulations and key forms

• Regulation S-X governs the form and content of financial statements; Regulation S-K governs non-financial disclosures (business description, risk factors, management's discussion and analysis (MD&A), executive compensation).
• Form S-1: registration statement for an initial public offering (IPO). Form S-3: short-form registration for seasoned issuers.

Form	Purpose	Deadline
10-K	Annual report with audited financial statements, MD&A, and (for accelerated filers) the auditor's internal control attestation	Large accelerated filer: 60 days; accelerated filer: 75 days; non-accelerated filer: 90 days
10-Q	Quarterly report with reviewed (not audited) interim statements — first three quarters only	Large accelerated and accelerated: 40 days; non-accelerated: 45 days
8-K	Current report of significant events: acquisitions or dispositions, change in auditor, director departures, bankruptcy, material cybersecurity incidents	Generally 4 business days after the event
Proxy statement (Schedule 14A)	Information for shareholder votes	Before the annual meeting

Filer status

Category	Public float
Large accelerated filer	$700 million or more
Accelerated filer	$75 million to under $700 million (and annual revenue of $100 million or more)
Non-accelerated filer	Under $75 million, or smaller reporting companies with revenue under $100 million

A smaller reporting company (public float under $250 million, or revenue under $100 million with float under $700 million) may use scaled disclosures, such as two years of audited financial statements instead of three years of income statements. Form 10-K Item 1C requires disclosure of cybersecurity risk management, strategy, and governance.

Segment reporting (ASC 280)

Management approach

An operating segment is a component that earns revenues and incurs expenses, whose operating results are regularly reviewed by the chief operating decision maker (CODM), and for which discrete financial information is available. Segment information is reported on the same basis used internally, even if that basis differs from Generally Accepted Accounting Principles (GAAP).

Quantitative thresholds — the 10% tests

An operating segment is reportable if it meets any one of these:

1. Revenue test: reported revenue (external and intersegment) ≥ 10% of the combined revenue of all operating segments.
2. Profit or loss test: the absolute amount of its profit or loss ≥ 10% of the greater of (a) combined profit of all segments reporting a profit, or (b) combined loss of all segments reporting a loss (in absolute terms).
3. Asset test: assets ≥ 10% of combined assets of all operating segments.

75% test: total external revenue of reportable segments must be at least 75% of consolidated revenue; if not, add segments until it is. A practical limit of about 10 reportable segments applies. Segments with similar economic characteristics may be aggregated.

Segment disclosures (updated by Accounting Standards Update (ASU) 2023-07)

• A measure of profit or loss and total assets for each reportable segment.
• Significant segment expenses regularly provided to the CODM, and an amount for "other segment items".
• The title and position of the CODM and how the CODM uses the reported measures.
• Reconciliations of segment totals to consolidated revenue, profit or loss, and assets.
• Most annual segment disclosures are now also required in interim periods. Entities with a single reportable segment provide all the disclosures.

Entity-wide disclosures

Required even for single-segment companies: revenue by product or service, revenue and long-lived assets by geographic area (domestic versus foreign), and the existence of any major customer providing 10% or more of revenue — with the total amount and the segments involved (the customer's name is not required).

Interim reporting (ASC 270)

US GAAP treats each interim period as an integral part of the annual period, not as a standalone (discrete) period.

Item	Interim treatment
Revenue and most costs	Recognized as incurred, on the same basis as the annual period
Costs benefiting several quarters (annual repairs, property taxes, advertising)	May be allocated across quarters
Income tax expense	Apply the estimated annual effective tax rate to year-to-date pretax income, then subtract tax expense already recognized
Inventory market decline	Recognize unless temporary and expected to recover by year-end
Temporary last-in, first-out (LIFO) liquidation expected to be replaced by year-end	Charge cost of sales at expected replacement cost
Gross profit method	Allowed for interim inventory estimates (disclose)
Unusual or infrequent items, discontinued operations	Recognized in the interim period in which they occur — not allocated
Changes in accounting principle	Retrospective application, as in annual reporting

Interim statements are condensed and must disclose seasonal effects, significant changes in estimates, and material events since the last annual report.

How it is tested

• Match an event or report to the correct SEC form and deadline.
• Apply the 10% and 75% tests to identify reportable segments.
• Compute interim-period income tax expense.
• Decide whether an item is allocated across quarters or recognized immediately.
