The Form F-3ASR Files Dataset is a record-by-record collection of every Form F-3ASR automatic shelf registration statement filed on EDGAR by foreign private issuers (FPIs) that qualify as well-known seasoned issuers (WKSIs). Each record corresponds to a single EDGAR submission identified by an 18-digit accession number and bundles the registration statement and base prospectus, every exhibit attached to it, and a structured metadata.json manifest. The form variant came into existence with the SEC's Securities Offering Reform on December 1, 2005, and the dataset's coverage begins with that effective date and runs to the present, distributed as monthly ZIP containers organized by year and month.

The dataset captures the population of F-3ASR filings made on EDGAR — the foreign private issuer counterpart to Form S-3ASR and the only shelf form that is both restricted to FPI WKSIs and automatically effective on filing under Rule 462(e). Each record is a complete EDGAR submission of one F-3ASR registration statement, physically organized as a directory whose name is the un-dashed accession number (for example 000121390025126785, corresponding to the dashed accession 0001213900-25-126785). Inside that directory sit the manifest and the SGML-wrapped document files: the F-3ASR registration statement and base prospectus, every exhibit attached to it (legal opinions, consents, indentures, underwriting and equity-distribution agreements, the iXBRL filing-fee exhibit, powers of attorney, and so on), and any prospectus-related supporting documents the registrant included at the time of filing.
Records are grouped into monthly ZIP containers organized by year and month (for example 2025/2025-12.zip); inside the container, each accession-number folder is one record. The dataset spans every F-3ASR filing made on EDGAR from December 2005 to the present and currently contains 7,186 records. Image attachments (GRAPHIC entries such as .jpg and .gif letterhead, signature scans, and figures) and the full submission .txt SGML envelope are intentionally omitted from the on-disk payload, although they remain enumerated in metadata.json -> documentFormatFiles with a resolvable documentUrl so they can be fetched from EDGAR if required. Files are distributed in HTML, JSON, TXT, and PDF formats reflecting the original submission encoding.
One record in the Form F-3ASR Files Dataset is a complete EDGAR submission of a single Form F-3ASR automatic shelf registration statement, identified by its 18-digit accession number. The directory bundles a structured metadata.json manifest together with the SGML-wrapped document files that make up the registration: the F-3ASR registration statement and base prospectus, every exhibit attached to it, and any prospectus-related supporting documents the registrant included at the time of filing.
Form F-3ASR is the foreign private issuer counterpart to Form S-3ASR: an automatic shelf registration statement filed under the Securities Act of 1933 by a well-known seasoned issuer (WKSI) that is also a foreign private issuer. The form variant came into existence with the SEC's Securities Offering Reform, which took effect on December 1, 2005 and created the WKSI category alongside Rule 462(e), the rule that makes a properly designated automatic shelf registration statement effective on filing without staff review. WKSI eligibility rests on a worldwide common-equity public float threshold (originally and currently $700 million) or, alternatively, on a track record of registered non-convertible debt issuance.
Functionally, an F-3ASR is a shelf prospectus. The registrant pre-registers, on a generic and forward-looking basis, the classes of securities (debt securities, ordinary shares, ADSs, preferred shares, depositary shares, warrants, rights, units, guarantees) that it may offer over a three-year window, and is then permitted to take down individual offerings by filing prospectus supplements. Because effectiveness is automatic under Rule 462(e), the cover page carries a legend stating that the registration statement "shall become effective upon filing with the Commission," and effectivenessDate in the manifest typically equals the calendar date of filedAt. The 333- shelf file number assigned at filing is recorded as fileNo inside the entity block of the manifest.
A record is organized as two layers stacked inside one accession folder.
The first layer is the metadata.json manifest. It is the single structured index for the record and serves as the authoritative source of truth for filer identification, dates, exhibit composition, and cross-links to EDGAR. It is produced once per accession and never refers to files outside the folder except by absolute URL.
The second layer is the document set. Every non-JSON file inside the folder is an EDGAR SGML <DOCUMENT> block whose <TEXT> payload is HTML (or, for older filings, plain text), wrapped between header tags that record the exhibit <TYPE>, the <SEQUENCE> number within the submission, the on-disk <FILENAME>, and a human-readable <DESCRIPTION>. The first sequence is always the registration statement itself; subsequent sequences are the exhibits in the order specified by Item 16 of Form F-3 (legal opinion, consents, indentures, underwriting agreement forms, fee table, powers of attorney, and so on). PDFs occasionally appear as supplementary or courtesy-formatted exhibits, and a small number of legacy filings include plain-text documents.
For the iXBRL-tagged filing-fee exhibit, the manifest carries an additional pointer in metadata.json -> dataFiles to the extracted XBRL instance (*_htm.xml); that extracted instance is not stored on disk but is reachable through its documentUrl. The inline-tagged HTML file itself is present in the folder and remains parseable end-to-end.
The manifest is a flat JSON object whose intentional, documented fields are:
formType (always "F-3ASR"), accessionNo in dashed form, an opaque internal id, and a human-readable description.filedAt is an ISO-8601 timestamp with timezone offset; effectivenessDate is the calendar date of automatic effectiveness, ordinarily equal to the filing date.linkToFilingDetails points to the primary registration HTML, linkToHtml to the EDGAR filing-index page, linkToTxt to the complete SGML submission text, and linkToXbrl to an XBRL instance when one exists (often empty for F-3ASR submissions whose only structured artifact is the fee exhibit).documentFormatFiles[]. One entry per file in the original submission, including those omitted from the on-disk payload (GRAPHIC images and the full .txt envelope). Each entry carries sequence, size, documentUrl, description, and type (e.g. F-3ASR, EX-5.1, EX-23.2, EX-FILING FEES, GRAPHIC).dataFiles[]. XBRL artifacts associated with the filing, in practice the extracted XML instance for the filing-fee exhibit when one exists.entities[]. Filer/registrant block: cik, companyName with role tag (e.g. "(Filer)"), irsNo, fileNo (the SEC 333- shelf number), filmNo, sic (with text description), stateOfIncorporation (an EDGAR country/state code, for example C3 for Australia, X0 for the United Kingdom), fiscalYearEnd, act (33 for the Securities Act), type (form type), and tickers[].seriesAndClassesContractsInformation[]. Populated only for fund-style filings; ordinarily empty for F-3ASR.<TYPE>F-3ASR)This is the largest file in the record and contains the substantive offering disclosure. Its internal organization follows Form F-3:
333- file number, principal executive office address, agent for service in the United States, ticker information, registration-statement caption, and the WKSI automatic-effectiveness legend invoking Rule 462(e). For foreign private issuers the cover page typically identifies whether the financial statements incorporated by reference are presented under IFRS as issued by the IASB or U.S. GAAP, and may carry an emerging-growth-company indicator where applicable.A short letter from issuer's home-country counsel (and, for ADSs or U.S.-law-governed debt, often a separate U.S. counsel opinion as EX-5.2) addressed to the issuer, opining that the securities to be issued have been duly authorized and, when issued and paid for in accordance with the registration, will be validly issued, fully paid, and (for shares) non-assessable; for debt, that the indenture has been duly authorized and the notes will be valid and binding obligations subject to standard bankruptcy/equity qualifications. The exhibit identifies the counsel firm, the body of law on which it opines (frequently the issuer's home jurisdiction such as Australia, the United Kingdom, Canada, the Netherlands, Bermuda, the Cayman Islands, Ireland, Israel, or Switzerland), the assumptions made, and the consent to inclusion. Letterhead images appear in the original submission as separate GRAPHIC files but are not included in the dataset payload.
Short, formulaic consent letters required under Section 7 of the Securities Act. Typical entries:
A self-contained HTML document that presents the structured filing-fee table as Inline XBRL. The document embeds facts under the ffd (filing fees) taxonomy together with dei entity facts, anchored by an issuer-level c_report context and per-line c_offering_* contexts. Typical reported facts include the security type, fee calculation rule (e.g. Rule 457(o), Rule 457(r)), proposed maximum aggregate offering price, fee rate, and fee due, with cross-references to previously paid offsets when the registrant is rolling forward unsold securities from a prior shelf. In practice these files are produced by fee-exhibit editors (for example Novaworks Fee Exhibit Editor) and reference an extracted *_htm.xml XBRL instance enumerated under metadata.json -> dataFiles. The exhibit type appears as either EX-FILING FEES or, in some submissions, the equivalent label EX-107.
Beyond EX-5.1, EX-23.x, and the fee exhibit, F-3ASR records frequently contain a subset of the Item 601 exhibits permitted for shelf registrations:
PDFs appear in some records, typically as courtesy-formatted versions of opinions or as graphic-heavy supporting exhibits.
GRAPHIC entries (e.g. image_001.jpg, signature scans, firm-letterhead bitmaps embedded inside opinions and consents) are excluded from the on-disk payload but remain enumerated in documentFormatFiles with resolvable EDGAR documentUrl values..txt SGML envelope is excluded; individual <DOCUMENT> blocks are present as separate files.*_htm.xml extracted from the iXBRL fee exhibit is referenced in dataFiles but is not stored on disk; the inline-tagged HTML file carries the same facts.EX-FILING FEES / EX-107) tagged in Inline XBRL using the ffd taxonomy, instead of being printed on the cover page. Records filed after the compliance date carry this new exhibit (often the only iXBRL artifact in the submission); records filed before that date carry the fee table on the cover page and have no EX-FILING FEES document.F-3ASR submissions have always been transmitted to EDGAR as SGML packages, but the encoding inside the <TEXT> blocks evolved:
<table> markup; PDF courtesy copies appear more often as ancillary exhibits.EX-FILING FEES / EX-107) embedding ffd: and dei: facts. This is the only iXBRL component an F-3ASR ordinarily carries; the registration statement and base prospectus themselves are not iXBRL-tagged because Form F-3ASR is not an Exchange Act report subject to financial-statement tagging.The dataset preserves the original SGML wrapper and the original HTML / iXBRL / PDF / text encodings for each document, so format-era differences are visible directly in the on-disk files.
metadata.json is the authoritative manifest; the on-disk file set is a strict subset of documentFormatFiles. To enumerate what is present locally, filter documentFormatFiles to entries whose type is not GRAPHIC and whose extension is not the full submission .txt.<TYPE> header inside each document or the type field in documentFormatFiles, rather than inferring from filenames. Filenames are filer/agent-specific (some use the ea<digits> ESL prefix; others use issuer-name-based slugs like *_ex5-1.htm) and are not standardized.effectivenessDate is meaningful but in practice mirrors filedAt for F-3ASR under Rule 462(e); divergence of a day or two reflects calendar/timezone alignment, not staff review.ffd facts in the inline HTML, while pre-2022 records require parsing the cover-page HTML table inside the registration statement.formType = "F-3ASR", a foreign stateOfIncorporation code, and references to Form 20-F or 40-F in the EX-23 consents is a reliable joint indicator that the registrant is a foreign private issuer. Some dual-listed Canadian issuers register under the MJDS using Form F-10 rather than F-3, so the F-3ASR population skews toward non-MJDS foreign issuers (European, UK, Israeli, Australian, Asian, and offshore-incorporated registrants).333- fileNo across records reconstructs the full life cycle of a given shelf, including post-effective amendments and the universe of takedowns referencing it.linkToXbrl is frequently empty, and seriesAndClassesContractsInformation is ordinarily empty for F-3ASR; these are expected absences rather than data gaps.Form F-3ASR is filed exclusively by foreign private issuers (FPIs) that qualify as well-known seasoned issuers (WKSIs).
foreign private issuer is defined in Securities Act Rule 405 / Exchange Act Rule 3b-4: a non-governmental issuer organized outside the United States, unless more than 50% of its voting securities are held by U.S. residents AND any of (a) a majority of officers or directors are U.S. citizens or residents, (b) more than 50% of assets are in the U.S., or (c) the business is principally administered in the U.S. Issuers failing the FPI test use domestic forms (S-3, S-3ASR).
WKSI status is tested under Rule 405 as of the most recent eligibility determination date (the later of the most recent shelf filing/amendment or, absent one, the most recent Form 20-F or 40-F annual report). To qualify, the FPI must:
The issuer must not be an ineligible issuer under Rule 405. Disqualifying conditions include blank-check or shell-company status, bankruptcy in the past three years (absent specified cures), late Exchange Act reports in the past 12 months, and certain securities-law-related administrative or judicial proceedings or anti-fraud injunctions. Ineligible-issuer status disqualifies an FPI from F-3ASR regardless of size, forcing fallback to Form F-3 or Form F-1.
Co-registrant structures are common: a majority-owned subsidiary may file alongside a WKSI parent (for example, where the parent fully and unconditionally guarantees the subsidiary's non-convertible debt).
F-3ASR filings are transactional, not periodic. A record arises whenever a qualifying FPI WKSI submits an automatic shelf registration statement or post-effective amendment to EDGAR. Effectiveness is governed by Rule 462(e): the registration statement (and any post-effective amendment) becomes effective immediately upon filing, with no staff review and no Section 8(a) waiting period, provided the registrant is a WKSI at the time of filing. Filing date equals effective date.
Triggering events that produce records in this dataset:
pay-as-you-go fees under Rule 456(b) and Rule 457(r) allow the F-3ASR to register an indeterminate amount of securities and defer registration fees until each takedown, calculated based on the dollar amount of securities being offered. Fees accompany the related Rule 424(b) prospectus supplement rather than the base F-3ASR.
Takedowns are not F-3ASR records. Each offering off an effective shelf is implemented through a Rule 424(b) prospectus supplement (typically 424B2, 424B3, 424B5, or 424B7) referencing the F-3ASR file number and relying on Rule 430B's mechanics for omitted information (specific terms, selling security holders, amounts, prices). These supplements are separate EDGAR submission types and are not counted in this dataset.
Form F-3ASR sits at the intersection of three conditions: foreign private issuer (FPI) status, well-known seasoned issuer (WKSI) qualification, and automatic effectiveness. Its closest neighbors relax or replace one of those conditions, or sit upstream/downstream of the shelf itself. Three axes separate F-3ASR from each: (1) domestic vs. FPI, (2) WKSI vs. non-WKSI, and (3) registration statement vs. takedown.
F-3 is the direct non-WKSI sibling. Both are FPI shelf registrations that incorporate Exchange Act reports by reference and produce a base prospectus for later takedowns. The differences are mechanical and economic:
Use F-3 when an FPI qualifies for short-form shelf treatment but cannot meet the WKSI float threshold; use F-3ASR when the FPI is a WKSI and wants to skip SEC review.
S-3ASR is the structural twin of F-3ASR for U.S. domestic registrants. Automatic effectiveness, WKSI eligibility, fee deferral, and unallocated shelves are essentially identical. The split is purely the issuer regime: S-3ASR filers report on Form 10-K/Form 10-Q; F-3ASR filers report on 20-F/6-K, and their base prospectuses commonly carry IFRS or home-country GAAP financials, enforceability-of-judgments language, and cross-border tax disclosure.
Use S-3ASR for domestic WKSIs; use F-3ASR for FPI WKSIs. The two datasets are not interchangeable.
Form S-3 is the domestic counterpart of F-3: reviewed by the SEC, effective only on staff action or after waiting period, with fees paid at filing. It shares no issuer population with F-3ASR (domestic vs. FPI is a hard rule-based divide), so it functions as a parallel reference rather than a substitute.
Use S-3 only for domestic non-WKSI shelf analysis; it is irrelevant to FPI samples.
F-1 is the catch-all FPI form for issuers ineligible for short-form treatment, most commonly IPOs and issuers without sufficient reporting history or float. Unlike F-3ASR, F-1 covers a single defined offering rather than a future shelf, permits only limited incorporation by reference, is always subject to SEC review, and carries the full standalone business, MD&A, and audited financials inside the prospectus rather than leaning on the 20-F.
Use F-1 for an FPI's IPO or first registered offering before F-3 eligibility matures; use F-3ASR once the issuer has graduated to seasoned, large-float, automatic-shelf status.
F-4 registers FPI securities issued in mergers, exchange offers, and other M&A transactions. The overlap with F-3ASR is only that both register FPI securities under the 1933 Act. F-4 is event-driven and transaction-specific (background of the merger, fairness opinions, target financials, pro formas, vote disclosures); F-3ASR is forward-looking and transaction-agnostic at filing.
Use F-4 to register securities issued as deal consideration; use F-3ASR for ordinary, open-ended capital-raising. A single issuer often files both.
The 424B family (424B1-B8 and 424H) contains the supplements that operationalize a shelf. This is the most important boundary in the neighborhood. The F-3ASR is the registration backbone, filed once and effective for up to three years; the 424B is the actual offering, filed at each takedown with pricing, underwriters, deal-specific terms, and use of proceeds. A complete picture of any one offering requires both.
Use 424B for offering-level analysis (pricing, frequency, underwriting); use F-3ASR for registration-capacity, shelf-availability, and issuer-eligibility analysis. They are complementary, not substitutes.
F-3ASR is narrowly defined by FPI status, WKSI qualification, and automatic effectiveness. Every neighbor drops one of these: F-3 drops automatic effectiveness; S-3ASR drops the FPI regime; S-3 drops both WKSI and FPI; F-1 drops short-form shelf treatment entirely; F-4 replaces the open-ended capital-raising purpose with a transaction-specific one; 424B sits downstream as the takedown layer. F-3ASR is not substitutable with any of these for analyses keyed to large-float cross-border WKSIs using the streamlined automatic-shelf process, but it pairs naturally with 424B for offering-level work and with 20-F/6-K for the incorporated periodic disclosures.
The Form F-3ASR Files Dataset serves a focused set of cross-border capital markets, securities law, credit, and research roles, each anchored to specific record components.
Origination and execution bankers covering FPI clients track active shelves, the three-year Rule 415 clock, and registered security types on the cover page. The plan of distribution signals whether ATM programs, forward sales, underwritten takedowns, or block trades are available. EX-FILING FEES iXBRL data exposes registered amounts, security classes, and pay-as-you-go carry-forwards, translating directly into pitchable capacity.
Debt bankers monitor FPI debt shelves: senior, subordinated, guaranteed, and hybrid instruments registered by issuers and finance subsidiaries. Base prospectus indenture summaries, guarantor structures, and ranking language frame future drawdowns. Plan-of-distribution provisions (firm commitment, best-efforts, dealer-manager) drive roadshow scoping and distribution allocation.
Counsel use the dataset as a precedent library. They focus on cover-page mechanics (incorporation, agent for service, WKSI checkbox), forward-incorporation tied to 20-F and 6-K, FPI-specific risk factors (home-country law, judgment enforceability, currency, sanctions, foreign tax), and plan-of-distribution boilerplate. EX-5.1 legality opinions, often pairing U.S. counsel opinions on debt with local-counsel opinions on share validity, are benchmarked for scope, assumptions, qualifications, and reliance.
In-house teams at FPIs use peer filings to confirm WKSI eligibility framing (worldwide float, seasoning, ineligible-issuer screen), validate cover-page mechanics, align EX-23 auditor consent format and dating, and pressure-test EX-FILING FEES table construction. The dataset also supports renewal cadence tracking and internal sign-off scoping for immediately effective filings.
IR teams benchmark shelf disclosures against home-jurisdiction and sector peers, focusing on risk factor structuring, use-of-proceeds language, dividend policy, ADR program references, and dual-listed share framing. Output supports drafting reviews ahead of three-year refreshes and prep for analyst questions on registered capacity.
Analysts detect new or refreshed shelves as issuance signals. The cover page (security types, selling-shareholder participation), plan of distribution (ATM, forward sale), and any selling-shareholder schedules feed dilution scenarios, share-count models, and price-target revisions.
Advisers on cross-border deals read effective shelves with broad security coverage and EX-FILING FEES capacity as proxies for an FPI acquirer's ability to fund announced or rumored deals through registered equity, convertibles, or debt without reopening SEC review. Target-side diligence uses the same signal to model stock consideration.
Credit researchers track registered debt capacity and structural features. They read the base prospectus description of debt securities, guarantor and subsidiary-issuer structures, ranking and subordination language, and indentures incorporated by reference. EX-FILING FEES quantifies remaining debt capacity, feeding supply forecasts, relative-value calls, and covenant comparisons.
Long-only and event-driven desks monitor supply overhangs in ADRs positions and study how FPIs frame political, currency, and home-country risk. F-3ASR filings paired with subsequent 424(b) supplements support timing around takedown announcements.
Engineering teams ingest cover pages, plan-of-distribution sections, EX-FILING FEES exhibits, and exhibit lists to populate shelf-tracking dashboards, FPI issuance pipelines, and compliance feeds sold to buy-side and sell-side clients.
Teams building cross-border filing assistants use F-3ASR as a focused corpus dense in WKSI, Rule 415, Regulation S, ADR, and home-country risk language, well suited to retrieval pipelines answering questions on shelf capacity, security types, opinion scope, and consent coverage.
The Form F-3ASR Files Dataset supports a narrow set of cross-border capital markets and SEC-disclosure workflows that depend on specific record components: the base prospectus, EX-5.1 legal opinion, EX-23 consents, and the iXBRL EX-FILING FEES exhibit. The use cases below tie each workflow to those components.
Parse the EX-FILING FEES iXBRL exhibit (ffd: facts under c_offering_* contexts) to extract proposed maximum aggregate offering price, security class, and any "previously paid" carry-forward offsets. Joining these per-line records by the 333- fileNo in metadata.json -> entities[].fileNo and then deducting subsequent 424B takedowns produces a live registered-but-unsold capacity figure for each ADR-listed FPI shelf.
For sell-side syndicate and DCM desks, aggregate the registered security types listed on the F-3ASR cover page (debt securities, ordinary shares, ADSs, preferred, warrants, units, guarantees) across the most recent three-year window using the dataset's monthly ZIP coverage. The result is a forward supply pipeline of FPI WKSI capacity by sector, home jurisdiction (stateOfIncorporation), and instrument class that can be refreshed weekly as new accessions land.
Because F-3ASR effectiveness is automatic under Rule 462(e), every new accession with formType = "F-3ASR" and effectivenessDate equal to filedAt is a fresh WKSI declaration. Reconciling each new filing against the prior three-year shelf for the same cik flags renewals, lapsed shelves, and issuers that dropped to non-WKSI status (visible as a switch from F-3ASR to F-3 in the same filer's record stream).
Extract auditor identity from each EX-23.1 consent letter and join to cik, sic, and stateOfIncorporation from the manifest to build a current and historical map of which audit firm signs the 20-F/40-F that each FPI WKSI incorporates by reference. Tracking changes across successive F-3ASR filings for the same shelf number surfaces auditor turnover and predecessor/successor relationships disclosed via additional EX-23.2/EX-23.3 consents.
Run text classification over the "Plan of Distribution" section of the base prospectus and over the EX-1.x form-of-agreement exhibits to label each shelf as supporting at-the-market programs (EX-1.1 equity-distribution agreements), firm-commitment underwritten takedowns, agency, dealer, or direct-sale execution. The labelled output drives ECM coverage targeting, ATM-program competitive intelligence, and forward-sale availability checks.
For all post-May-2022 records, programmatically harvest ffd: facts (rule cited under Rule 457(o)/457(r), fee rate, fee due, offering price) from the inline-tagged HTML to build a structured fee-revenue series for the SEC and a per-issuer ledger of cumulative registered amounts. For pre-2022 records, fall back to parsing the cover-page fee table inside the registration statement HTML.
Build a precedent library of home-country counsel opinions keyed by jurisdiction (Australia, UK, Netherlands, Bermuda, Cayman, Ireland, Israel, Switzerland) and by registered security type. Comparing scope, assumptions, qualifications, and the split between U.S.-counsel debt opinions and local-counsel share-validity opinions accelerates first-draft mark-ups for new FPI shelf filings.
For announced or rumored cross-border deals, look up the acquirer's effective F-3ASR by cik, read the registered security mix on the cover page, and net registered capacity using the EX-FILING FEES exhibit against intervening 424B takedowns. The remaining capacity is a direct read on whether the acquirer can fund stock, convert, or debt consideration without reopening SEC review.
The dataset is a focused corpus for retrieval and fine-tuning on WKSI mechanics, Rule 415/462(e) language, ADR-versus-ordinary-share descriptions, enforcement-of-judgments risk factors, home-country tax disclosure, and Item 601 exhibit conventions. The combination of structured metadata.json, the base prospectus, and tightly typed exhibits (EX-5.1, EX-23.x, EX-FILING FEES) supports both retrieval indexing and supervised tasks such as exhibit classification and risk-factor section segmentation.
Group records on metadata.json -> entities[].fileNo (the 333- shelf number) to assemble the original F-3ASR, any F-3ASR/A and POS AM amendments, and downstream 424B takedowns into a single life-cycle record. This is the basis for shelf-utilization rate analysis, time-to-first-takedown studies, and three-year expiry-tracking dashboards.
The Form F-3ASR Files Dataset is available through three access methods: a JSON index API for metadata and container discovery, a single archive download for the entire dataset, and per-container downloads for incremental retrieval. Containers are distributed in ZIP format and bundle HTML, JSON, TXT, and PDF files extracted from each filing. The dataset starts at 2005-12-01 and currently covers form type F-3ASR.

The dataset covers Form F-3ASR, the foreign private issuer counterpart to Form S-3ASR. F-3ASR is an automatic shelf registration statement filed under the Securities Act of 1933 by a well-known seasoned issuer (WKSI) that is also a foreign private issuer, and it becomes effective immediately on filing under Rule 462(e) without SEC staff review.
One record represents a complete EDGAR submission of a single Form F-3ASR registration statement, identified by its 18-digit accession number. The record is a directory containing a structured metadata.json manifest and the SGML-wrapped document files (registration statement and base prospectus, EX-5.1 legal opinion, EX-23.x consents, EX-FILING FEES iXBRL fee exhibit, and any other Item 601 exhibits the registrant attached).
Form F-3ASR is filed exclusively by foreign private issuers (FPIs) that qualify as well-known seasoned issuers (WKSIs). To qualify, the FPI must meet Form F-3 General Instruction I.A registrant and transaction requirements and satisfy either a $700 million worldwide non-affiliate float test or a $1 billion three-year registered non-convertible debt issuance test, and must not be an ineligible issuer under Rule 405.
The dataset starts on December 1, 2005 — the effective date of Securities Offering Reform (Release 33-8591), which created the F-3ASR variant — and runs to the present. There is no pre-EDGAR paper analogue because the form did not exist before that date.
The dataset is distributed as monthly ZIP containers organized by year and month (for example 2025/2025-12.zip). Each container holds accession-number folders, and each folder contains a metadata.json manifest plus the original HTML, JSON, TXT, and PDF files that make up the EDGAR submission, with the original SGML document wrappers preserved.
S-3ASR is the structural twin for U.S. domestic WKSIs and is filed by issuers that report on Form 10-K/10-Q rather than Form 20-F/6-K. Form F-3 is the FPI non-WKSI shelf and is subject to SEC staff review rather than automatic effectiveness. F-3ASR is the only form that combines FPI status, WKSI qualification, and Rule 462(e) automatic effectiveness in a single registration.
No. Each offering off an effective F-3ASR shelf is implemented through a Rule 424(b) prospectus supplement (typically 424B2, 424B3, 424B5, or 424B7) under a separate accession number, and these supplements are not part of an F-3ASR record. Post-effective amendments filed as F-3ASR/A or POS AM are included as separate records under their own accession numbers, sharing the same 333- shelf file number.
