SEC & EDGAR Glossary
ASC accounting standards, XBRL filing mechanics, SEC rules, and IFRS equivalents, with analyst-grade depth. Beat Index pulls every data point directly from EDGAR XBRL filings with no vendor adjustments. 61 terms.
1
10-K Filing
The annual report every US public company must file with the SEC within 60-90 days of its fiscal year end. Contains audited financial statements, MD&A, risk factors, and business description.
🔍 Investor Lens
Analysts read the 10-K before any other document. The MD&A section reveals management's own view of the business; the risk factors section shows what could go wrong. Cross-reference the narrative against the numbers to spot inconsistencies.
💡 Example
Think of the 10-K as a company's annual school report card; except it's legally required to be honest, audited by an independent accountant, and covers everything from revenue to lawsuits to what keeps the CEO up at night.
10-Q Filing
The quarterly financial report filed with the SEC within 40-45 days of each of the first three fiscal quarters. Contains unaudited financial statements and an MD&A update. No 10-Q is filed for Q4; the 10-K covers that.
🔍 Investor Lens
The 10-Q is where analysts track whether the annual thesis is holding quarter by quarter. Pay attention to sequential changes in gross margin and working capital; they often signal problems before the annual report confirms them.
💡 Example
If the 10-K is the annual report card, the 10-Q is the mid-term progress report. Three per year, less detailed, but still legally filed with the SEC and the fastest way to see how the year is unfolding.
13F Filing (Institutional Holdings)
Quarterly report filed by investment managers with $100M+ in assets under management. It discloses all US equity and convertible debt holdings at quarter-end. Filed within 45 days of each quarter close.
🔍 Investor Lens
Track what famous investors (Buffett, Ackman, Dalio) are holding via 13F. If a stock gets loaded by multiple smart-money investors, that is often a signal worth noticing. But remember: 13Fs are up to 45 days old by the time you see them. Positions may have already changed.
💡 Example
Imagine a list published quarterly showing what your smartest friends are keeping in their investment portfolios. By the time you read it, they have already made moves. But it tells you what they believed was good six weeks ago.
2
20-F Filing (Foreign Annual Report)
Annual report filed by foreign private issuers (companies incorporated outside the US but traded on US exchanges). It contains audited financials reconciled to GAAP or IFRS, MD&A, and risk factors. Equivalent to the 10-K for non-US companies.
🔍 Investor Lens
Foreign companies (ASML, AZN, NVO, Toyota) file 20-Fs instead of 10-Ks. The financials may be in IFRS, not US GAAP, so do not compare them directly to US competitors without adjusting. Watch for currency exposure and geopolitical risk in the MD&A section.
💡 Example
Think of it as a foreign company's annual report card written in a slightly different language and grading system. You need a translator (GAAP reconciliation) to compare it fairly to US companies.
4
40-F Filing (Canadian Issuers)
The annual report form filed with the SEC by Canadian companies listed on US exchanges under the Multijurisdictional Disclosure System (MJDS). Equivalent to the 20-F for other foreign private issuers, but allows Canadian companies to use Canadian GAAP (IFRS) and Canadian securities disclosure documents.
🔍 Investor Lens
If you hold a Canadian company listed on a US exchange (like Shopify or Barrick Gold), their annual report to the SEC is filed as a 40-F, not a 10-K. It follows Canadian disclosure rules and uses IFRS accounting. The financials are directly comparable but formatted differently; the risk factors section references Canadian securities law rather than US regulations.
💡 Example
Shopify (SHOP) files a 40-F with the SEC as a Canadian company listed on NYSE. The financials are in US dollars and follow IFRS; so analysts looking at Canadian tech companies need to understand IFRS lease treatment under IFRS 16, for example, which differs from ASC 842.
424B4 (IPO Prospectus)
The final prospectus filed at or just before an IPO. It includes the confirmed IPO price, final share count, underwriter names, lockup terms, and all risk disclosures from the S-1.
🔍 Investor Lens
The 424B4 is your last chance to read the fine print before IPO pricing. Pay close attention to the lockup expiration date (usually 90-180 days). When insiders can finally sell, the stock often drops. Also note underwriter fees, typically 3-7% of gross proceeds.
💡 Example
It is the final menu at a restaurant before you order. Your last look at the price, what you are getting, and who is cooking before you commit to dinner and hand over your money.
6
6-K Filing (Foreign Current Report)
Current report filed by foreign private issuers for material events such as earnings releases, acquisitions, or leadership changes. Filing timelines are more flexible than the US 8-K (often 4-15 days post-event depending on home country rules).
🔍 Investor Lens
Foreign companies file 6-Ks for big announcements. The timing is usually slower than 8-Ks, so news often appears in the local press first. If a 6-K hits the SEC and you have not heard anything yet, it could be an earnings surprise worth reading immediately.
💡 Example
It is the foreign company equivalent of the 8-K. But their home government does not require them to file as quickly, so news often surfaces more slowly than with US companies.
8
8-K/A (Amended Current Report)
An amended version of a previously filed 8-K. It corrects errors, adds missing information, or updates prior disclosures. Companies must file an 8-K/A when the original contained material inaccuracies or omissions.
🔍 Investor Lens
When you see an 8-K/A, the company got something wrong in the first filing. Read both side-by-side to see exactly what changed. Sometimes the amendment quietly downgrades guidance or acknowledges a problem that was absent or buried in the original.
💡 Example
It is like sending a correction email to your whole team saying 'Actually, I meant to say the opposite of what I wrote earlier.' It makes you wonder whether the organisation is disorganised or hiding something.
8-K Filing
A current report filed with the SEC within 4 business days of a material event (earnings, acquisition, executive change, bankruptcy). It discloses time-sensitive information that could affect stock price.
🔍 Investor Lens
Check the 8-K immediately after major announcements. This is where the company tells the SEC (and you) about earnings misses, leadership changes, lawsuits, or deal problems. If they file an 8-K on Friday evening, something material just happened.
💡 Example
Imagine your employer posts a notice on the break-room wall that they are being acquired. The 8-K is that official notice to everyone at once. Not an email to insiders first.
A
Accelerated Filer
An SEC filing status assigned to companies with a public float between $75M and $700M. Accelerated filers must file 10-Ks within 75 days of fiscal year end and 10-Qs within 40 days. They are also subject to SOX 404(b) external auditor attestation of internal controls.
🔍 Investor Lens
Filing status affects how quickly you get financial information. Large accelerated filers (public float >$700M) must file within 60 days; faster. Non-accelerated filers (<$75M float) get 90 days. If a company is late filing, they submit an NT 10-K and their status affects when a material weakness must be disclosed. Faster filings generally correlate with more mature financial infrastructure.
💡 Example
A company with a $400M public float is an accelerated filer; its annual report is due 75 days after year end. If it misses that deadline and files an NT 10-K extension, that is a yellow flag worth tracking.
ASC 205-40 (Going Concern Disclosures)
The FASB standard requiring management to evaluate whether substantial doubt exists about a company's ability to continue as a going concern for 12 months after the financial statement issuance date. If substantial doubt exists, management must disclose the conditions and, if applicable, their mitigation plans.
🔍 Investor Lens
A going concern disclosure is the most serious warning flag in financial reporting. It means management and their auditors believe there is meaningful doubt the company will survive the next 12 months without raising capital, restructuring debt, or executing some other remediation. Companies receiving going concern opinions typically see immediate stock price declines of 30-50% and face lender covenant triggers.
💡 Example
WeWork received a going concern opinion in its 2019 10-K; within months the IPO was pulled, Adam Neumann resigned, and SoftBank had to provide an emergency rescue package. The going concern disclosure was the formal signal of what the market already suspected.
ASC 230 (Statement of Cash Flows)
The FASB standard governing the presentation of the statement of cash flows. Requires classification of cash flows into operating, investing, and financing activities. Companies can choose direct or indirect method for operating cash flows; virtually all US public companies use the indirect method.
Formula
Operating Cash Flow (indirect) = Net Income
+ Non-cash charges (D&A, SBC, impairment)
+/- Changes in working capital
- Deferred revenue adjustments
+/- Other operating items🔍 Investor Lens
The cash flow statement is the hardest financial statement to manipulate; cash is cash. When earnings and cash flow diverge significantly, the cash flow statement tells the truth. Always compare net income to operating cash flow: if a company reports rising net income but declining OCF, working capital deterioration or aggressive accruals are the likely cause.
💡 Example
WeWork reported positive EBITDA while burning massive cash; the cash flow statement showed the truth: enormous lease payments, cash-funded losses, and working capital deterioration that EBITDA completely obscured.
ASC 280 (Segment Reporting)
The FASB standard requiring public companies to report financial information for each operating segment that is reviewed regularly by the chief operating decision maker (CODM). Segments are defined by management's internal reporting structure, not by product line or geography per se.
🔍 Investor Lens
Segment disclosures are some of the most valuable data in a 10-K. Companies often report one consolidated number but generate wildly different profitability across divisions. Amazon Web Services versus Amazon retail is the canonical example. Segment operating income margins reveal which parts of the business are profitable and which are being cross-subsidised. When a company collapses segments or stops reporting a segment separately, that often signals deteriorating performance in the hidden unit.
💡 Example
Google/Alphabet resisted separately disclosing YouTube and Google Cloud revenue for years, bundling them into Google Services and Google Other. When forced by investor pressure to break these out, it revealed YouTube's massive revenue scale and Google Cloud's rapid growth. This information had been hidden in the aggregated segment.
ASC 323 (Equity Method Investments)
The FASB standard governing investments where an investor has significant influence (typically 20-50% ownership) but not control. The investor records their proportionate share of the investee's net income/loss each period, rather than only dividends received. The investment balance increases with income and decreases with losses or dividends.
Formula
Equity Method Investment (balance) = Initial Cost
+ Share of investee net income
- Share of investee net losses
- Dividends received
+/- Other comprehensive income adjustments🔍 Investor Lens
Equity method investments can significantly affect earnings but not cash flow. The investor records their share of profits but only receives cash when dividends are paid. A company with large equity investments can show income from affiliates while collecting no actual cash. Conversely, losses from equity investees flow through the income statement even if the investee is doing fine strategically.
💡 Example
Toyota holds 20% of Subaru. Accounting for this under ASC 323, Toyota records 20% of Subaru's profits each quarter as income from equity method investments on its income statement, even though Toyota only receives cash when Subaru pays dividends.
ASC 350 (Goodwill Impairment)
The FASB standard governing intangible assets and goodwill. Requires annual impairment testing of goodwill (and more frequent testing if triggering events occur). If a reporting unit's carrying value exceeds its fair value, goodwill is written down. An impairment charge hits the income statement.
Formula
Impairment loss = Carrying Value of Reporting Unit - Fair Value of Reporting Unit
(Recognised only if Carrying Value > Fair Value; limited to goodwill balance)🔍 Investor Lens
Goodwill impairment is management admitting they overpaid for an acquisition. The charge is non-cash and does not affect operating cash flow; however, it reveals that the business acquired is worth less than what was paid. Watch the timing: impairment charges often appear in a new CEO's first year (the 'big bath', or writing down predecessor's mistakes) or during economic downturns when fair values fall below book value.
💡 Example
AOL Time Warner wrote down $54B of goodwill in 2002 (one of the largest in history), admitting that the $165B AOL-Time Warner merger was a catastrophic overpayment. The goodwill had sat on the balance sheet at full value for two years before the impairment.
ASC 360 (Long-Lived Asset Impairment)
The FASB standard requiring companies to test long-lived assets (property, plant & equipment, finite-lived intangibles) for impairment when events suggest the carrying value may not be recoverable. A two-step test applies: first, recoverability (is the carrying amount less than undiscounted future cash flows?); second, if not, measure impairment as excess of carrying value over fair value.
Formula
Recoverability test: If carrying amount > sum of undiscounted future cash flows → impairment exists
Impairment loss = Carrying Amount - Fair Value of Asset🔍 Investor Lens
ASC 360 impairments are retrospective admissions that capital was deployed poorly. Unlike goodwill impairment (ASC 350), which has no recoverability test, ASC 360 uses the undiscounted cash flow test as a first hurdle. This means impairment is only triggered when cash flows are expected to be quite poor. When you see PP&E impairment charges, a business unit or asset group is generating less cash than its book value suggests.
💡 Example
Macy's recorded billions in store impairments under ASC 360 as it closed locations. This admission meant the carried value of its retail stores exceeded the present value of expected future cash flows from those stores. These non-cash charges reflected the secular decline of mall retail.
ASC 470 (Debt Classification and Modification)
The FASB standard governing debt accounting, including: when debt is classified as current vs. long-term, how to account for debt modifications and extinguishments, and convertible debt instruments. A debt covenant violation that makes debt callable triggers reclassification to current liabilities.
Formula
Debt discount amortisation (effective interest method):
Interest Expense = Beginning Carrying Amount × Effective Interest Rate
Carrying Amount increases by (Interest Expense - Cash Interest Paid)🔍 Investor Lens
Covenant violation triggers under ASC 470 can suddenly move long-term debt to current liabilities, dramatically worsening the current ratio overnight. Watch the debt footnote for: (1) covenant compliance status, (2) waiver requests, (3) upcoming maturity concentration. A company with $2B of long-term debt that has 'received a waiver' on a covenant breach has already flagged financial stress in the footnotes.
💡 Example
When Bed Bath & Beyond violated debt covenants in 2022, their long-term debt was reclassified to current under ASC 470. The balance sheet deteriorated sharply on paper, triggering lender concern and accelerating the liquidity spiral that led to bankruptcy in 2023.
ASC 606 (Revenue Recognition)
The FASB accounting standard governing when and how companies recognise revenue. Establishes a five-step model: (1) identify the contract, (2) identify performance obligations, (3) determine transaction price, (4) allocate price to obligations, (5) recognise revenue when each obligation is satisfied.
Formula
Revenue recognised when (or as) performance obligation is satisfied
Allocated price = (SSP of obligation / Total SSP of all obligations) × Transaction price🔍 Investor Lens
ASC 606 changed when companies can book revenue, and the timing matters. Software companies that bundle licenses with multi-year support now must spread revenue recognition over the contract term. This slowed reported revenue for many SaaS companies when the standard was adopted in 2018-2019. When a SaaS company reports 'remaining performance obligations' (RPO), that is the ASC 606 disclosure of contracted revenue not yet recognised. This serves as a leading indicator of future revenue.
💡 Example
Before ASC 606, Microsoft could recognise Windows license revenue at point of sale. Under ASC 606, if the license is bundled with ongoing updates (a performance obligation), revenue must be spread over the update period. This is why Microsoft's transition to subscription revenue accounting also changed its revenue recognition pattern.
ASC 718 (Stock-Based Compensation)
The FASB standard requiring companies to recognise the fair value of employee stock options, restricted stock units (RSUs), and performance awards as compensation expense over the vesting period. Before ASC 123R (the predecessor), stock options were not expensed. The move to fair value expensing significantly increased reported costs for tech companies.
Formula
SBC Expense = Fair Value at Grant Date × Number of Awards Vesting
Option Fair Value typically estimated using Black-Scholes model🔍 Investor Lens
Stock-based compensation is a real cost that dilutes your ownership. When tech companies report 'non-GAAP earnings' excluding SBC, they are asking you to ignore the cost of paying employees in equity. That cost is real: it reduces your ownership percentage when options are exercised or RSUs vest. Compare SBC as a percentage of revenue. Above 15-20% for a mature company is a yellow flag.
💡 Example
Uber reported $4.6B in stock-based compensation in 2021: a real economic cost to shareholders in the form of dilution. By excluding this from 'Adjusted EBITDA,' Uber turned a massive GAAP loss into a positive non-GAAP number. Investors who accepted that framing were ignoring a significant cost.
ASC 740 (Income Taxes)
The FASB standard governing the accounting for income taxes, including current tax expense and deferred tax assets and liabilities (DTAs and DTLs). Deferred taxes arise from timing differences between when income is recognised for financial reporting versus tax purposes.
Formula
Current Tax Expense = Taxable Income × Statutory Tax Rate
Deferred Tax Asset/Liability = Temporary Difference × Enacted Future Tax Rate
Effective Tax Rate = Total Tax Expense / Pre-tax Income🔍 Investor Lens
Effective tax rate often differs significantly from the statutory rate (21% US federal). The difference reveals important information. A company with a 10% effective tax rate may be using R&D credits, foreign tax structures, or stock option deductions. Watch for the effective tax rate: (1) if it is negative (tax benefit), the company may be burning through deferred tax assets from prior losses; (2) sudden spikes in ETR often signal a deferred tax asset valuation allowance.
💡 Example
When Amazon had cumulative operating losses in its early years, it built up deferred tax assets representing future tax benefits. When it returned to profitability, it could use those DTAs to reduce actual cash taxes paid. This is why Amazon's cash taxes were well below its book tax expense for years.
ASC 805 (Business Combinations)
The FASB standard governing how companies account for mergers and acquisitions. Requires the acquiring company to: (1) identify all acquired assets and assumed liabilities at fair value, (2) recognise identifiable intangible assets separately from goodwill, and (3) record goodwill as the excess of purchase price over fair value of net assets.
Formula
Goodwill = Purchase Price - Fair Value of Identifiable Net Assets
Fair Value of Net Assets = Identified Assets (at FV) - Assumed Liabilities (at FV)🔍 Investor Lens
Every acquisition creates a purchase price allocation that determines future earnings. The intangibles allocated at acquisition (customer relationships, technology, brand) are amortised, reducing reported earnings. Goodwill is not amortised but must be impairment-tested annually. When you see 'amortisation of acquired intangibles' in a non-GAAP reconciliation, the company is telling you to ignore the cost of their acquisitions.
💡 Example
When Microsoft acquired Activision Blizzard for $69B, the purchase price allocation under ASC 805 required them to identify and value Activision's game franchises (Call of Duty, World of Warcraft), developer teams, and technology. The excess of the $69B over those fair values became goodwill on Microsoft's balance sheet.
ASC 815 (Derivatives and Hedging)
The FASB standard governing the accounting for derivative instruments and hedging relationships. All derivatives must be recorded at fair value on the balance sheet. Gains and losses are recognised in earnings unless the derivative qualifies for hedge accounting, in which case some volatility flows through Other Comprehensive Income (OCI).
🔍 Investor Lens
Derivatives appear in many companies' financials: interest rate swaps, foreign currency forwards, commodity hedges. Under ASC 815, these must be disclosed at fair value, which can create significant balance sheet and income statement volatility if hedges do not qualify for hedge accounting treatment. For airlines, commodity companies, and multinationals, derivatives disclosure in the 10-K footnotes is critical reading.
💡 Example
Delta Air Lines buys jet fuel hedges that are accounted for under ASC 815. When fuel prices fall sharply (as in 2020), their hedges become liabilities. Delta had to post collateral and recorded losses on derivatives, even though it was benefiting from lower fuel costs operationally. The hedge accounting footnote explains which losses flow through earnings versus OCI.
ASC 820 (Fair Value Measurement)
The FASB standard defining fair value as the price received to sell an asset or paid to transfer a liability in an orderly transaction. Establishes a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs other than quoted prices), Level 3 (unobservable inputs, or management estimates).
🔍 Investor Lens
Level 3 assets are the ones to watch closely. Banks holding Level 3 mortgage securities, private equity firms holding Level 3 fund investments, or insurance companies holding Level 3 structured products are all using management models to determine asset values. During financial stress, Level 3 assets become illiquid and the models fail. This is why Level 3 disclosures widened dramatically during 2008 and 2020.
💡 Example
Goldman Sachs discloses each quarter how much of its trading book is Level 1 (liquid, exchange-traded), Level 2 (model-priced with market inputs), and Level 3 (illiquid, internally modelled). The 2008 crisis hit because Level 2 mortgage CDOs could not find buyers, effectively becoming Level 3 overnight.
ASC 842 (Lease Accounting)
The FASB standard that requires companies to recognise most operating leases on the balance sheet as a right-of-use (ROU) asset and corresponding lease liability. Effective for public companies from 2019. Previously, operating leases were off-balance-sheet; ASC 842 ended that practice.
Formula
ROU Asset = PV of lease payments + Initial direct costs - Lease incentives
Lease Liability = PV of remaining lease payments (discounted at incremental borrowing rate)🔍 Investor Lens
ASC 842 made company balance sheets significantly larger in 2019 without changing the economic reality. A retailer like Target suddenly showed tens of billions in 'right-of-use assets' and 'operating lease liabilities', new lines that didn't exist before. These are store leases that were always obligations but now appear on the balance sheet. Understand this before comparing 2019+ leverage ratios to pre-2019 data.
💡 Example
When McDonald's adopted ASC 842, its balance sheet grew by roughly $13B in ROU assets and lease liabilities, representing the present value of thousands of restaurant leases that were always economic obligations but had previously been disclosed only in footnotes.
C
CIK (Central Index Key)
A unique numeric identifier assigned by the SEC to every entity that files with EDGAR: companies, funds, individuals, and foreign private issuers. The CIK is the primary key for all EDGAR queries and API calls.
🔍 Investor Lens
You rarely need to use the CIK directly, but knowing it exists helps you navigate EDGAR. If you search EDGAR for 'Apple,' you might find multiple entities. The CIK uniquely identifies Apple Inc. (CIK 0000320193) versus any other Apple-named entity. Financial data APIs use CIK as the unique identifier.
💡 Example
When Alphabet rebranded from Google, its ticker changed from GOOG to Alphabet's current structure; its CIK (0001652044) remained unchanged, so historical filing data remained searchable and connected.
D
DEF 14A (Proxy Statement)
The definitive proxy statement filed before shareholder meetings. It contains voting items (board elections, compensation, mergers), executive compensation details, and governance information.
🔍 Investor Lens
Vote your shares using the DEF 14A. It shows you what proposals management wants you to approve, how much executives are paid, and whether there are red flags (excessive compensation, related-party deals). Do not skip this; it is your shareholder voice.
💡 Example
It is like the agenda and voting materials for a condo board meeting. It tells you who is running, what they want to change, and how much they are being paid to run the building.
DEI (Document and Entity Information)
A standard block of XBRL data in every SEC filing that identifies the filer. Contains machine-readable metadata including: entity name, CIK, ticker symbol, SIC code, fiscal year end date, filing date, document type, public float, shares outstanding, and filer status (accelerated/large accelerated/smaller reporting company).
🔍 Investor Lens
DEI data is the filing's cover page in structured form. While you will never look at DEI directly, the platforms you use rely on it to know which company filed, what period it covers, and how many shares are outstanding. Shares outstanding in the DEI block is the most recently updated count, more current than the annual report financial statements in some cases.
💡 Example
When a company completes a stock split, the updated share count appears in the DEI block of the very next SEC filing, sometimes weeks before analysts update their models. Beat Index reads this automatically from EDGAR, which is why the share count in the dashboard reflects the most recently filed data.
E
EDGAR
Electronic Data Gathering, Analysis, and Retrieval; the SEC's public database where every US public company files its financial reports, proxy statements, registration statements, and ownership disclosures. Beat Index's primary data source.
🔍 Investor Lens
EDGAR is the most authoritative financial data source in the world for US companies, and it is free. Any financial figure cited by a broker, analyst, or media outlet ultimately traces back to an EDGAR filing. When data conflicts, EDGAR wins. Beat Index reads EDGAR directly so the numbers you see are exactly what management certified and filed.
💡 Example
Think of EDGAR as the SEC's filing cabinet; every 10-K, 10-Q, 8-K, proxy, and insider trade is stored there, publicly accessible to anyone. When Apple files its annual report, it goes into EDGAR within minutes and Beat Index reads it automatically.
EDGAR Full-Text Search
The SEC's full-text search tool (efts.sec.gov) that indexes the complete text of SEC filings, allowing keyword searches across all public company filings since 1996. Useful for finding specific contract terms, risk disclosures, accounting policy language, and related-party transaction descriptions across the entire filing universe.
🔍 Investor Lens
EDGAR full-text search is a free research tool most investors do not know exists. You can search for any phrase across all SEC filings; for example, searching 'material adverse change' AND a company name in a specific year, or finding all companies that disclosed a specific accounting risk before it became public. It is the fastest way to see how a company described a specific topic across multiple filings.
💡 Example
During the Theranos fraud investigation, journalists and analysts used EDGAR full-text search to find all companies and investment vehicles connected to Theranos board members; cross-referencing the SEC's own database to map the network of connected entities.
F
Form 3 (Initial Insider Ownership)
Filed within 10 days of an insider (director, officer, or 10% shareholder) joining a company or becoming a reporting person. It discloses their initial ownership stake at that moment.
🔍 Investor Lens
A Form 3 marks the moment someone with power is now required to disclose their trades. Check their starting stake: are they walking in with meaningful skin in the game, or is this a purely salaried title? Executives with large initial stakes are more aligned with shareholders.
💡 Example
It is like announcing that a new executive has just joined the company and disclosing how much stock they already own, or do not own. You learn immediately whether they are financially tied to the outcome.
Form 4 (Insider Transaction)
Filed by company insiders (officers, directors, 10% shareholders) within 2 business days of buying or selling company stock. It discloses the transaction price, volume, and resulting ownership level.
🔍 Investor Lens
Watch insider buying: if the CEO or board members are loading up on their own stock at these prices, that is a bullish signal. If they are selling large amounts, that is often a warning. Form 4s show real money where mouths are.
💡 Example
It is like seeing your neighbour suddenly buy three more houses on your street: if they are betting big on the area, maybe the neighbourhood is about to boom. If they are selling up, they may know something you do not.
Form 5 (Annual Insider Ownership Change)
Filed within 45 days of a company's fiscal year-end. It reports all insider transactions and holdings changes during the year that were not previously disclosed on Form 4 filings, such as gifts, small open-market trades, or plan-based transactions.
🔍 Investor Lens
Form 5 is the annual insider report card: it catches all the trades that slipped through the cracks of daily Form 4 disclosures. Add up the full-year insider buying versus selling and look for patterns. A year of net insider buying across multiple executives is a meaningful signal.
💡 Example
Think of it as a yearly summary showing all your neighbours' property transactions (buying, selling, gifting) so you can see the full picture of who is investing in the street for the long term.
I
IAS 1 (Presentation of Financial Statements)
The IASB standard setting out the overall requirements for the presentation of financial statements: the income statement, balance sheet, statement of changes in equity, cash flow statement, and notes. Unlike US GAAP, IAS 1 allows classification of expenses by nature (materials, labour, depreciation) OR by function (cost of sales, SG&A); companies choose.
🔍 Investor Lens
IAS 1 is why European company income statements look different from US GAAP ones. A German company may report expenses 'by nature' (raw materials, personnel costs, depreciation) rather than the US 'by function' (COGS, R&D, SG&A). This makes it harder to compute gross margin directly from the income statement, because material costs and labour are not separated by product versus administrative function.
💡 Example
Volkswagen uses a by-nature income statement. You see 'cost of materials: €150B' and 'personnel expenses: €30B' but not a gross profit line. Toyota (US GAAP on its 20-F) uses a by-function statement with a clear gross profit disclosure. Comparing their gross margins requires reconstructing VW's income statement, which is possible but requires additional work.
IAS 36 (Impairment of Assets)
The IASB equivalent of ASC 350 and ASC 360 combined. Requires companies to assess at each reporting date whether there is any indication that an asset may be impaired. If indicators exist, the recoverable amount is estimated: the higher of fair value less costs of disposal and value in use (discounted future cash flows).
Formula
Recoverable Amount = MAX(Fair Value less costs of disposal, Value in Use)
Impairment Loss = Carrying Amount - Recoverable Amount (if positive)🔍 Investor Lens
IAS 36 uses a single 'recoverable amount' test rather than the two-step US GAAP approach, which means IFRS companies may recognise impairments that US GAAP companies would pass on the recoverability hurdle. This can make IFRS reporters look more conservative in downturns. Watch for goodwill impairment tests on cash-generating units (IAS 36 terminology for US GAAP's 'reporting units').
💡 Example
AstraZeneca tests its drug pipeline assets under IAS 36. If a Phase 3 trial fails, the asset's recoverable amount falls to zero and an impairment charge is required immediately. This is why IFRS biotech income statements show large, lumpy impairment charges when drug programmes fail.
IFRS 15 (Revenue from Contracts with Customers)
The IASB's equivalent of ASC 606, using the same five-step model for revenue recognition. Effective globally from 2018. Adopted by all IFRS-reporting jurisdictions including the EU, UK, Japan, and Australia. Foreign private issuers filing 20-F with the SEC use IFRS 15.
Formula
Same five-step model as ASC 606:
1. Identify contract(s)
2. Identify performance obligations
3. Determine transaction price
4. Allocate to performance obligations
5. Recognise when obligation is satisfied🔍 Investor Lens
IFRS 15 and ASC 606 are substantially converged. The same five-step model applies. For investors comparing a US company (ASC 606) to a European or Asian competitor (IFRS 15), revenue recognition principles should be broadly comparable. Differences emerge in specific guidance areas; IFRS 15 has less prescriptive implementation guidance, giving more room for judgement.
💡 Example
AstraZeneca (IFRS 15 reporter) and Pfizer (ASC 606 reporter) both report vaccine revenue under a converged five-step model. An investor can compare their revenue recognition timing with reasonable confidence that the frameworks are broadly equivalent.
IFRS 16 (Leases)
The IASB's equivalent of ASC 842, requiring lessees to recognise a right-of-use asset and lease liability for virtually all leases. Effective 2019. Unlike ASC 842, IFRS 16 does not distinguish between operating and finance leases from the lessee's perspective. All leases are treated as finance leases, with depreciation and interest expense replacing rent expense.
Formula
Lease Liability = PV of lease payments (at lessee's incremental borrowing rate)
ROU Asset = Lease Liability + Initial direct costs + Prepaid payments - Incentives
Interest Expense = Lease Liability × Discount Rate
Depreciation = ROU Asset / Lease Term (straight-line)🔍 Investor Lens
IFRS 16 is stricter than ASC 842 in one key way: all leases are effectively treated as finance leases under IFRS, meaning rent expense disappears from EBITDA and is replaced by depreciation (in EBITDA) and interest (below EBITDA). This inflates EBITDA for IFRS reporters vs. US GAAP reporters with similar lease profiles; a critical comparability trap when valuing US vs. European peers.
💡 Example
Ryanair (IFRS 16 reporter) and Southwest Airlines (ASC 842 reporter) both have massive aircraft lease portfolios. Under IFRS 16, Ryanair shows higher EBITDA because aircraft lease costs appear as depreciation and interest, not operating expenses. A direct EBITDA comparison between the two overstates Ryanair's profitability relative to Southwest.
IFRS 9 (Financial Instruments)
The IASB standard governing the classification, measurement, and impairment of financial instruments. Replaces IAS 39. Introduces the expected credit loss (ECL) model for impairment. It requires banks and other lenders to provision for expected future losses rather than waiting for losses to occur (the 'incurred loss' model of IAS 39 that delayed recognition in the 2008 crisis).
🔍 Investor Lens
IFRS 9's expected credit loss model matters most for banks and financial companies. Under IFRS 9, banks must immediately recognise expected losses on loans, even loans that are currently performing, based on forward-looking economic scenarios. This is more conservative than the US GAAP CECL model (ASC 326) which has similar intent but different mechanics. During economic downturns, IFRS 9 provisions spike early, hurting reported earnings but also signalling management's economic outlook.
💡 Example
When COVID hit in March 2020, HSBC (IFRS 9) immediately recognised billions in expected credit loss provisions. These were recognised before any loans had actually defaulted because the standard requires forward-looking loss provisioning. This front-loaded the pain into 2020 but also meant reserves were already built when actual defaults arrived.
Inline XBRL (iXBRL)
A format that embeds XBRL tags directly within human-readable HTML financial filings, rather than in a separate XBRL file. The SEC mandated iXBRL for large accelerated filers from 2020 and all filers from 2022. iXBRL allows both human reading and machine parsing of the same document.
🔍 Investor Lens
Before iXBRL, companies submitted two separate files: the human-readable 10-K and a separate XBRL instance document. iXBRL combines them; the financial statements you read on EDGAR are the same document that contains the structured data. This reduced errors from discrepancies between the two formats and made the filing process simpler.
💡 Example
Go to any recent Apple 10-Q on the SEC EDGAR viewer and click on the revenue number. It will show you the XBRL tag ('us-gaap:RevenueFromContractWithCustomerExcludingAssessedTax'), the value, the period, and the filing context; this is iXBRL working in real time. Beat Index extracts exactly this data automatically for every filing.
M
Material Weakness
A deficiency, or combination of deficiencies, in a company's internal control over financial reporting (ICFR) where there is a reasonable possibility that a material misstatement of the financial statements will not be prevented or detected on a timely basis. Disclosed in 10-K filings.
🔍 Investor Lens
A material weakness disclosure is a red flag that deserves immediate attention; it means the company's own auditors found that their financial controls cannot reliably catch errors. This does not mean fraud has occurred, but it does mean the financial statements carry higher risk. Watch for: (1) whether the weakness was self-identified or auditor-identified, (2) remediation timeline, (3) whether a restatement follows.
💡 Example
GE Capital disclosed multiple material weaknesses in the mid-2010s related to long-term care insurance reserves, which preceded a $6.2B charge and subsequent credit downgrade, exactly the scenario the control framework is designed to catch early.
MD&A (Management Discussion and Analysis)
A required narrative section in every 10-K and 10-Q where management explains the company's financial results, material trends, liquidity position, and known risks. One of the most analytically valuable parts of any SEC filing.
🔍 Investor Lens
The MD&A is management's own explanation of what happened and why. Read it before accepting any financial result at face value. Look for changes in language year-over-year; if management suddenly adds new risk language or stops discussing a metric they previously highlighted, that is a signal worth investigating.
💡 Example
When Netflix saw subscriber growth slow, the MD&A was where management first explained the competitive dynamics and market saturation factors, often before analysts had pieced it together from the raw numbers alone.
N
Non-GAAP Reconciliation
A required disclosure when a company presents a non-GAAP financial measure (such as Adjusted EBITDA, Adjusted EPS, or Free Cash Flow) alongside GAAP results. The reconciliation table shows exactly what items were added back or excluded to get from GAAP to the non-GAAP figure.
🔍 Investor Lens
Non-GAAP metrics are management's preferred view of performance, which means they almost always look better than GAAP. Always check the reconciliation table: are they excluding stock-based compensation (a real cost), restructuring charges (year after year?), or amortisation of acquired intangibles (inflated by acquisitions)? A company that repeatedly adds back 'one-time' items is telling you their one-time items are recurring.
💡 Example
Salesforce reported GAAP net losses for years while showing 'non-GAAP operating income' that excluded billions in stock-based compensation. The reconciliation table revealed the full cost of employee equity awards that GAAP correctly includes but management preferred to exclude.
NT 10-K (Late Filing Notice)
A notice filed when a company cannot meet the standard 10-K filing deadline. It requests an automatic 15-day extension and must disclose the reason for the delay. Filed under Rule 12b-25.
🔍 Investor Lens
An NT 10-K is a yellow flag. Late filings sometimes signal accounting troubles, management transitions, audit disputes, or material restatements in progress. If a normally reliable company files an NT 10-K, dig into why before you hold or add to your position.
💡 Example
It is like telling your landlord you need more time to get the rent together this month. It raises questions about your finances even if you eventually pay on time.
Q
Quiet Period
A period during which a company or underwriter restricts communications about a security under SEC rules. Two distinct types: (1) IPO quiet period (10-40 days post-IPO during which underwriters cannot publish research); (2) earnings quiet period (informal practice of companies ceasing market guidance 2-4 weeks before earnings release).
🔍 Investor Lens
The IPO quiet period ends when underwriters can publish initial coverage; often leading to a predictable stock move as sell-side initiates with 'Buy' ratings. Be sceptical of first-day-of-coverage upgrades from IPO underwriters. For earnings quiet periods, if a company usually provides monthly updates and goes silent 3 weeks before earnings, that silence is meaningful.
💡 Example
After Uber's 2019 IPO, the major underwriting banks (Goldman, Morgan Stanley, etc.) waited 25 days before publishing their research coverage. Within days of the quiet period lifting, most initiated with 'Buy' ratings; a pattern so predictable it is known as the 'quiet period bounce.'
R
Regulation FD (Fair Disclosure)
An SEC rule requiring that when a public company discloses material non-public information to certain market participants (analysts, institutional investors), it must simultaneously or promptly make that same information public. Prevents selective disclosure that advantages certain investors.
🔍 Investor Lens
Regulation FD is why companies hold public earnings calls with question-and-answer sessions; they cannot tell Goldman Sachs something they won't tell you. If a company executive accidentally discloses something material in a private meeting, the company must file an 8-K immediately to make it public. This rule is why 8-K filings sometimes appear at odd times.
💡 Example
If a CFO tells a hedge fund manager at a private dinner that 'next quarter is looking weaker than expected' before making a public announcement, that is a Reg FD violation; the SEC can fine the company and executive.
Regulation S-K
The SEC regulation that prescribes the non-financial statement disclosure requirements for registration statements and periodic reports. S-K governs what goes into the business description, risk factors, MD&A, executive compensation, and legal proceedings sections of a 10-K.
🔍 Investor Lens
Regulation S-K is why every 10-K has the same structure: business description, then risk factors, then financial statements, then executive compensation. The uniformity makes cross-company comparison easier. When you read that 'Item 1A. Risk Factors' is a required section, that requirement comes from Reg S-K.
💡 Example
When the SEC adopted new human capital disclosure requirements in 2020 under Reg S-K Item 101(c), every public company had to start disclosing information about their workforce; headcount, turnover, training. This information had not been uniformly disclosed before and created new data points for analysts.
Restatement
A correction of previously issued financial statements due to an error, misapplication of accounting standards, or fraud. Companies file restated financials via an amended 10-K (10-K/A) or 10-Q (10-Q/A). Restatements require re-audit and can trigger SEC enforcement investigations.
🔍 Investor Lens
A restatement is a serious event; it means previously reported numbers were wrong. The stock typically falls 10-30% on restatement announcement. More concerning than the restatement itself is what it signals: poor internal controls, aggressive accounting, or management intent to mislead. Check whether the restatement was self-reported or identified by auditors; self-reported signals better governance.
💡 Example
GE restated results multiple times between 2017-2021 related to its power business and insurance portfolio, eventually triggering an SEC investigation and forcing investors to reconsider years of reported earnings.
Risk Factors (10-K Section 1A)
A required SEC filing section where management discloses all material risks that could adversely affect the company's business, financial condition, or results. Legally mandated under Regulation S-K Item 105.
🔍 Investor Lens
Risk factors are written by lawyers to be comprehensive, which makes them long but also useful. The most important signals: (1) new risks added since the prior filing, (2) risks promoted to a more prominent position, (3) anything quantified (e.g. 'a 100bp increase in interest rates would cost us $50M annually'). Management cannot later claim they didn't warn you.
💡 Example
SVB Financial Group's 2022 10-K risk factors extensively discussed interest rate risk on its held-to-maturity portfolio: the exact risk that caused its collapse in March 2023. Investors who read those filings had early warning.
S
S-1 Registration Statement
The primary registration form used by private companies going public (IPO). It contains audited financials, business description, risk factors, executive compensation, and use-of-proceeds for the IPO.
🔍 Investor Lens
Before you buy an IPO, read the S-1 from start to finish. It is the only time management is required to lay out all the risks, competitive threats, and how they will spend your money. If you cannot understand the business after reading the S-1, do not buy the stock.
💡 Example
Think of an S-1 as a job application: before a company hires you (sells you stock), it has to tell you everything about itself, including the good, the bad, and the risks.
S-3 Filing (Shelf Registration)
An SEC registration statement allowing eligible companies to register securities for future sale without filing a new prospectus each time. Once the S-3 is effective, the company can issue shares or debt 'off the shelf' in multiple tranches over a 3-year period.
🔍 Investor Lens
An S-3 shelf registration is a dilution warning. When a company registers $500M of shares on an S-3, they can sell those shares any time over the next three years, often at the worst time for existing shareholders (when the stock is elevated, or to fund cash-burning operations). Watch for S-3 filings from companies with negative free cash flow: they are likely planning equity raises.
💡 Example
Tesla filed an S-3 shelf registration in 2020 registering $5B of stock. It then sold shares in multiple tranches that year, raising $5B in fresh capital while the stock was near all-time highs. Existing shareholders were diluted but the company avoided a cash crisis.
S-4 (Merger Registration)
Registration statement filed by acquiring companies in merger or acquisition transactions. It includes both companies' audited financials, combined pro forma results, voting details, and the full merger agreement.
🔍 Investor Lens
When an S-4 appears, a merger is in motion. Read it to understand the deal economics: the exchange ratio, earnout structure, closing conditions, and break-up fees. Compare the pro forma margins to each company on a standalone basis; that is where synergy claims live or die.
💡 Example
Imagine two businesses deciding to merge. The S-4 is the detailed contract everyone sees: what each party owns, what the combined entity will look like, and who gets what if the deal falls apart.
SC 13D (Activist Ownership)
Filed within 10 calendar days of acquiring 5%+ of a company's stock with intent to influence management, seek board seats, or push for strategic changes. Identifies the buyer, their funding source, and their stated plan.
🔍 Investor Lens
A 13D often signals an activist investor (Icahn, ValueAct, Elliott) is planning to shake things up. Read the Intent section carefully, as they are telling the SEC if they want board seats or a full takeover. This filing can move the stock 10%+ in hours.
💡 Example
It is like a property developer announcing they have bought 5% of your building and plan to push for renovations and a new management committee. Now everyone knows there is a new player with skin in the game and an agenda.
SC 13G (Passive Ownership)
Filed within 10 calendar days of acquiring 5%+ of a company passively, with no intent to control or influence management. Typically used by index funds, ETFs, and long-term buy-and-hold investors.
🔍 Investor Lens
A 13G usually means a large passive investor (Vanguard, BlackRock, State Street) has crossed 5% through routine buying. It is less dramatic than a 13D, but if a 13G later converts to a 13D, something has changed and the situation becomes much more interesting.
💡 Example
It is like a pension fund letting everyone know it now owns 5% of your company, but it is just holding for the long term with no plans to change anything. Completely routine, unless it later changes its mind.
SEC Comment Letter
A written inquiry from the SEC's Division of Corporation Finance to a company requesting clarification or additional disclosure on a submitted filing. Both the SEC letter and the company's response are made public on EDGAR after a 20-business-day confidentiality period.
🔍 Investor Lens
SEC comment letters are underused by retail investors but are a goldmine. They show exactly what the SEC found confusing or potentially misleading in a company's filings, and the company's response often reveals management's accounting rationale. Search EDGAR for a company's correspondence files. If the SEC is asking repeated questions about revenue recognition or segment reporting, that is a signal worth tracking.
💡 Example
Amazon received multiple SEC comment letters questioning its segment disclosure practices: the SEC wanted more granularity on AWS profitability long before Amazon voluntarily separated it. The comment letters are available publicly on EDGAR.
SEC EDGAR
The Securities and Exchange Commission's Electronic Data Gathering, Analysis, and Retrieval system. The public database where all US public companies file their mandatory disclosures: 10-K, 10-Q, 8-K, proxy statements, and hundreds of other form types. Freely accessible to anyone.
🔍 Investor Lens
EDGAR is the primary source for institutional financial analysis. Beat Index pulls all financial data directly from EDGAR XBRL filings: ensuring what you see is exactly what the company filed, with no vendor adjustments or estimation. When you see data on this platform, you can always trace it back to the original EDGAR filing.
💡 Example
Every public company in the US must file its annual and quarterly reports with the SEC. Those reports live on EDGAR: think of it as a public library where every company's financial history is stored and searchable for free. It is the starting point for any serious analysis of a US-listed stock.
SIC Code (Standard Industrial Classification)
A four-digit code assigned by the SEC to classify a company's primary business activity. Used for regulatory purposes, peer comparison, and as the basis for many financial analysis frameworks. Predates NAICS but remains the SEC's standard.
🔍 Investor Lens
SIC codes matter because they determine peer groups. A bank (SIC 6020-6029) is analysed completely differently from a retailer (SIC 5200-5999). Different metrics, different ratios, different regulatory treatment apply to each. When reading a 10-K, the SIC code at the top of the filing tells you what regulatory and accounting regime the company operates under.
💡 Example
Amazon's SIC code of 5961 (catalogue and mail-order houses) makes it look like a retailer, when in reality it earns the majority of its operating income from AWS (cloud computing). Analysts who rely on SIC for peer grouping will draw incorrect conclusions.
Significant Deficiency
A deficiency in internal control over financial reporting that is less severe than a material weakness but important enough to merit attention by those responsible for financial oversight. Reported to the audit committee but not required to be disclosed publicly.
🔍 Investor Lens
Significant deficiencies are not publicly disclosed. You won't see them in the 10-K. However, if a company has a history of material weaknesses, it often started with unaddressed significant deficiencies. The distinction matters: material weakness means disclosed, while significant deficiency involves private audit committee communication only.
💡 Example
A company with a weak month-end close process that sometimes produces incorrect accrual entries might receive a significant deficiency finding from its auditor. This is not serious enough for a public material weakness disclosure, but it is a warning sign that controls need tightening.
SOX 302 (CEO/CFO Certification)
Section 302 of the Sarbanes-Oxley Act requires the CEO and CFO to personally certify in every 10-K and 10-Q that: (1) they have reviewed the filing, (2) it contains no material misstatements, (3) financial statements fairly present results, and (4) they have disclosed all significant deficiencies and material weaknesses to the audit committee.
🔍 Investor Lens
SOX 302 certifications make the CEO and CFO personally liable for the accuracy of financial statements. Criminal penalties apply for false certifications. This is why executive turnover following a restatement is common: the prior executives certified statements that later proved inaccurate. If a CEO or CFO resigns abruptly near filing time, that timing warrants scrutiny.
💡 Example
When Enron's CEO Jeff Skilling and CFO Andrew Fastow signed SOX-equivalent certifications, they were personally attesting that the financial statements were accurate. This created the legal basis for criminal prosecution when the fraud was discovered.
U
US-GAAP Taxonomy
The official library of XBRL tags defined by FASB for labelling financial data in US GAAP filings. Contains thousands of standardised element names for every financial statement line item. Updated annually to reflect new accounting standards. Companies must use taxonomy elements where applicable or create custom extensions.
🔍 Investor Lens
The US-GAAP taxonomy is what makes financial data from different companies comparable. If Apple and Microsoft both tag their revenue with 'us-gaap:RevenueFromContractWithCustomerExcludingAssessedTax,' a platform can automatically compare them. When companies use custom extensions instead of standard tags, it creates data gaps that require manual mapping.
💡 Example
The revenue tag changed from 'us-gaap:SalesRevenueNet' (pre-2018) to 'us-gaap:RevenueFromContractWithCustomerExcludingAssessedTax' (post-ASC 606). Any system that only looks for the new tag will miss pre-2018 revenue data. Beat Index handles both tag versions. This is exactly the type of data pipeline detail that separates reliable financial platforms from unreliable ones.
X
XBRL
Extensible Business Reporting Language. A structured, machine-readable XML format that the SEC requires companies to use when tagging their financial data in filings. Each data point (revenue, net income, etc.) is tagged with a standardised taxonomy identifier that allows automated extraction and comparison.
🔍 Investor Lens
XBRL is what makes programmatic financial data analysis possible at scale. Beat Index uses XBRL tags from SEC EDGAR filings directly, without data vendors or manual transcription. Understanding XBRL helps analysts audit data quality: if a metric looks wrong, checking the underlying XBRL tag reveals whether it is a tagging error or a genuine business anomaly.
💡 Example
Before XBRL, financial data in SEC filings was plain text. A human had to read it and retype the numbers. XBRL wraps each number in a label (like a barcode) that a computer can read. Revenue becomes a tagged value that a computer can extract. Computers can then compare revenue across thousands of companies in seconds without anyone reading a single document.
XBRL (eXtensible Business Reporting Language)
An XML-based open standard for tagging financial data in SEC filings. The SEC mandated XBRL tagging for large accelerated filers from 2009. Every numeric value in a financial statement (revenue, assets, EPS, etc.) is tagged with a standardised label from the US-GAAP or IFRS taxonomy, making financial data machine-readable.
🔍 Investor Lens
XBRL is why data aggregators (Bloomberg, FactSet) and platforms like Beat Index can automatically extract financial data from SEC filings without manual entry. Before XBRL, financial data from filings had to be hand-entered or scraped from PDF/HTML; this was error-prone and slow. XBRL allows any company's revenue figure to be automatically identified, extracted, and compared across thousands of companies within minutes of filing.
💡 Example
When Apple files its 10-K, every revenue figure, every asset line, every EPS number is tagged with an XBRL label. The revenue tag is 'us-gaap:RevenueFromContractWithCustomerExcludingAssessedTax'. This allows Beat Index to automatically find Apple's revenue without reading a table or scraping an HTML page.
