The Form 10-D dataset contains the complete EDGAR history of periodic distribution reports filed by asset-backed securities (ABS) issuing entities, together with all attached exhibits. It covers 395,000+ files from 2005 to the present, totaling approximately 35 GB. Each record is one full EDGAR submission — the primary 10-D or 10-D/A document, all exhibit files (servicer reports, certifications, compliance statements) — for a single distribution period of a single securitization trust. The dataset is survivorship-bias-free: trusts that have fully wound down, defaulted, or been deregistered remain in the historical record alongside active issuers.
This is the longest continuous public record of post-issuance ABS performance in the SEC system, spanning RMBS, CMBS, auto loan, credit card, student loan, CLO, and other asset-backed structures across the full credit cycle from pre-crisis vintages through the present.

Each record represents one complete EDGAR submission of Form 10-D or Form 10-D/A. The unit of observation is one distribution period for one ABS issuing entity — typically a securitization trust or special-purpose vehicle. A trust filing monthly produces roughly 12 records per year.
The dataset packages every file in each submission: the 10-D form body, servicer reports, distribution certificates, compliance statements, certifications, images, and any other attachments. Files are in their original submitted formats: HTML, TXT, PDF, XML, GIF, and JPG.
Form types included: 10-D (originals) and 10-D/A (amendments correcting or superseding a prior report for the same distribution period).
Asset classes represented: RMBS (prime, subprime, Alt-A, jumbo, home equity), CMBS, auto loan and auto lease ABS, credit card receivables ABS, student loan ABS (FFELP and private), equipment loan and lease ABS, floorplan ABS, CLOs, and niche structures such as timeshare, container lease, and cell tower securitizations.
What is excluded: Transaction formation documents (prospectuses, PSAs, indentures) filed under registration statements; ABS annual reports (Form 10-K); material event reports (Form 8-K); ABS-EE asset-level data (separate EDGAR submissions under Regulation AB II); non-reporting ABS (Rule 144A, Regulation D); and non-EDGAR servicer reports distributed through trustee portals or Bloomberg.
The primary document is an HTML file (plain-text ASCII in older filings) organized around six required disclosure items defined by Form 10-D under Regulation AB, plus a signature block.
Item 1 — Distribution and Pool Performance Information is the substantive core of every 10-D. Required disclosures include: distribution amounts by class (principal and interest paid to each tranche, including shortfalls or deferrals); outstanding class balances with pool factors; pool collections (scheduled and unscheduled principal, interest, servicing fees, swap payments); beginning and ending pool balance; delinquency statistics at 30-59, 60-89, and 90+ days past due; default and loss statistics (new defaults, cumulative defaults, recoveries, net losses, cumulative net loss rates); prepayment rates (CPR, SMM, or other applicable metric); credit enhancement status (reserve fund balances, overcollateralization, excess spread, trigger test results); and servicer advances. In practice, many issuers satisfy Item 1 by incorporating the servicer report exhibit by reference, placing all substantive performance data in the attached exhibit rather than the primary document.
Item 2 — Legal Proceedings: Material pending legal proceedings involving the issuing entity, depositor, or servicer. Almost always brief or stated as "none" in performing transactions.
Item 3 — Sales of Unregistered or Exempt Securities: Generally stated as inapplicable.
Item 4 — Defaults upon Senior Securities: Payment defaults on the ABS securities. Substantive when a class experiences a shortfall, interest deferral, or principal write-down.
Item 5 — Submission of Matters to a Vote of Security Holders: Almost universally inapplicable.
Item 6 — Exhibits: An exhibit index listing all attached exhibits by number, description, and filename.
Signatures: Signed by an authorized officer of the depositor, servicer, or administrator acting on behalf of the issuing entity.
Exhibits are frequently the most data-rich component of a 10-D submission, often exceeding the primary document in analytical value.
Exhibit 99.1 — Servicer Report (Distribution Date Statement) is the central exhibit in nearly all 10-D filings, prepared by the master servicer, sub-servicer, trustee, or securities administrator. It typically includes: remittance and distribution tables with cash flow allocation by class; pool-level statistics (aggregate balance, WAC, WART, pool factor); delinquency aging schedules; default and loss summaries; prepayment data (CPR, SMM); reserve and credit enhancement tables with trigger test results; revolving pool metrics for credit card and student loan structures; and pool stratification tables (geographic distribution, LTV bands, FICO distribution, loan size bands, property type). Format varies substantially by asset class, servicer, trustee, and deal vintage. There is no SEC-mandated standard layout — machine extraction of specific fields typically requires asset-class-specific and often issuer-specific parsing logic.
Exhibit 33 — Certifications (Rule 13a-18 / 15d-18): Brief, formulaic attestation documents regarding the accuracy of the distribution report, structurally analogous to Sarbanes-Oxley certifications but tailored to ABS reporting.
Exhibit 36 — Servicer Compliance Statements (Items 1122 / 1123): Annual statements of compliance with minimum servicing criteria and accounting firm attestation reports. Most commonly filed with the annual 10-K but sometimes attached to 10-D filings.
Other exhibits may include material contract amendments (Exhibit 10), distribution agent or indenture trustee certificates, static pool data, computational materials, tax-related certifications, and REMIC compliance statements.
Before Regulation AB (pre-2006), ABS issuers used ad hoc Form 8-K filings for periodic reporting. Regulation AB (effective January 2006) established the six-item structure that remains in use today. Regulation AB II (effective 2016 for new shelf offerings) strengthened compliance requirements and introduced asset-level data reporting, but asset-level data files are filed on Form ABS-EE, not as 10-D exhibits. Early filings (2005-2009) are more likely to use plain-text ASCII with fixed-width tables; from approximately 2008 onward, HTML predominates. Some servicer reports are filed as PDF, requiring OCR or text-layer extraction.
The EDGAR registrant on each Form 10-D is an ABS issuing entity — a special-purpose trust or vehicle that holds a segregated pool of financial assets and distributes cash flows to securityholders. Entity structures include grantor trusts (RMBS pass-throughs), owner trusts (auto, equipment ABS), master trusts (revolving credit card and student loan ABS), Delaware statutory trusts, and other single-transaction vehicles.
Although the trust is the registrant, the filing is prepared and submitted by the depositor — typically a wholly owned subsidiary of the originating sponsor (a bank, captive auto finance company, or mortgage originator). The servicer, often an affiliate of the sponsor, produces the servicer report that supplies most of the substantive data. Neither the depositor nor the servicer is the Exchange Act reporting entity; they act on behalf of the trust.
Only ABS issuing entities whose securities were registered under the Securities Act of 1933 and that carry ongoing Exchange Act reporting obligations file Form 10-D. Privately placed ABS (Rule 144A, Regulation D) are absent. This is a meaningful limitation: a substantial share of overall ABS issuance, particularly post-2008, is unregistered.
Form 10-D is triggered by each distribution date — the contractually scheduled date on which the trust distributes collected principal and interest to securityholders. Filing cadence follows the transaction's own distribution calendar, not a fixed quarterly cycle. Most ABS transactions pay monthly (~12 filings per year per trust). Some CMBS and CLO structures pay quarterly. A small number distribute semi-annually.
The filing deadline is 15 calendar days after each distribution date. Because distribution dates vary by transaction (the 15th, the 25th, the last business day), 10-D filings are spread across the calendar month rather than clustering on a single deadline.
A trust's 10-D obligation begins when its securities are Exchange Act-registered and continues until: the securities are fully paid down and the trust winds up; reporting is suspended under Section 15(d) (holders of record fall below 300); or the trust files Form 15 to deregister. Mortgage trusts from 2006 with 30-year collateral pools may still be filing decades later.
A 10-D/A supersedes the original 10-D for the same distribution period and CIK. Both versions appear in the dataset. To obtain the authoritative version, select the most recent filing date for a given CIK and period-of-report pair.
Both are filed by the same ABS trust CIKs. 10-D follows the distribution cycle (typically monthly); 10-K is annual. A single trust may produce 12+ 10-D filings per 10-K. 10-D reports period-specific tranche payments, waterfall detail, delinquency and loss figures, and servicer remittance data. 10-K provides a cumulative annual view with servicer compliance assessments (Items 1122/1123), updated pool and transaction information, and legal proceedings. ABS issuers are generally exempt from providing audited financial statements under Regulation AB, so the 10-K for an ABS trust is structurally different from an operating company's 10-K. Period-by-period cash flow tracking requires 10-D; annual compliance and pool summaries require 10-K.
ABS-EE provides loan-level data in structured XML (individual balances, rates, payment status, origination characteristics). 10-D provides trust-level and tranche-level distribution summaries without individual asset detail. ABS-EE was introduced under Regulation AB II (effective November 2016) and covers only new public offerings on Form SF-3, while 10-D has been filed since 2005. The two are complementary: ABS-EE shows what happened at the loan level; 10-D shows the resulting tranche-level distributions.
10-D is cycle-driven, filed on a predictable post-distribution schedule. 8-K is event-driven, triggered by material developments such as servicer replacements, early amortization events, or defaults under the trust agreement. A performing trust files 10-D monthly for years and may never file an 8-K. Monitoring ABS trusts requires both: 10-D for the continuous performance record, 8-K for inflection points.
ABS issuing entities file periodic distribution reports on Form 10-D under Rules 13a-17 / 15d-17 instead of quarterly reports on Form 10-Q. The filer populations do not overlap: 10-Q covers operating companies; 10-D covers passive ABS trusts. There is no MD&A in a 10-D because there is no operating business.
Servicer reports contain much of the same data and are frequently attached as 10-D exhibits. The key difference is regulatory status: 10-D is a mandatory SEC filing on EDGAR, freely available and subject to certification requirements. Standalone servicer reports are contractual obligations under the PSA, often requiring investor portal access. The exhibit portion of this dataset captures servicer reports that were filed with the SEC, frequently containing more granular data than the 10-D filing body itself.
ABS portfolio analysts and structured credit portfolio managers track tranche distributions, pool factor updates, delinquency aging, net loss rates, prepayment speeds, and credit enhancement levels from servicer report exhibits. The period-of-report field and CIK enable monthly time series across a trust's full life for vintage comparison across RMBS, auto, credit card, student loan, and CLO deals.
Rating agency surveillance analysts extract delinquency rates, cumulative losses, overcollateralization levels, and trigger test outcomes to assess whether pool performance remains consistent with tranche rating assumptions. The dataset's coverage from 2005 through the subprime crisis provides the empirical history against which rating models are calibrated.
Bank and insurer risk teams pull net loss rates, delinquency trends, prepayment speeds, and credit enhancement erosion to feed internal risk models, calculate expected losses, and produce regulatory capital figures under Basel III securitization risk weights.
ABS servicer and trustee compliance teams verify that distribution reports were filed on time with required Regulation AB disclosures, confirm required exhibits are present, and maintain auditable compliance records using accession numbers and EDGAR timestamps.
Securities lawyers and ABS litigation counsel review filings for Regulation AB/AB II compliance and reconstruct month-by-month pool performance timelines in rep-and-warranty disputes, trustee breach claims, and servicing failure litigation.
Prepayment and default modelers build and calibrate models using monthly CPR, CDR, loss severity, and recovery rate data from servicer report exhibits. Full credit cycle coverage enables tail risk calibration and vintage analysis across origination years.
ABS data engineers build automated pipelines to ingest, parse, and normalize 10-D filings and servicer report exhibits into structured databases, handling format variability across servicers, trustees, asset classes, and deal vintages.
Securitization researchers use the longitudinal 10-D record as an empirical source for studying originator incentive effects, credit enhancement behavior under stress, servicer performance variation, and securitization market dynamics across credit cycles.
Build time series of 30/60/90+ day delinquency rates, cumulative net losses, and loss severities by combining CIK and period-of-report fields across consecutive filings for a trust. Stratify by origination vintage using trust names to compare pool deterioration curves across RMBS, auto, or credit card deals. The dataset's coverage from 2005 through the subprime crisis provides the empirical baseline for vintage-level stress benchmarking.
Extract tranche-level principal and interest payments, overcollateralization balances, reserve fund levels, and trigger test pass/fail outcomes from Exhibit 99.1 servicer reports. Flag trusts where excess spread compression, subordination erosion, or OC shortfalls approach step-down or early amortization thresholds before they appear in rating agency actions.
Pull monthly CPR, SMM, CDR, and recovery rate data from servicer report exhibits to construct calibration inputs for prepayment and credit loss models. Segment by asset class and originator using trust-name parsing to isolate systematic differences in underwriting quality and prepayment behavior across sponsors and deal vintages.
Compare the servicer identity in the signature block and Exhibit 33 certifications across consecutive 10-D filings for the same CIK to identify servicer transfers. Cross-reference filing dates against contractual deadlines to flag late filings. Check for missing required exhibits to audit Regulation AB disclosure completeness across a portfolio of trust positions.
Assemble the complete month-by-month filing history for a specific trust CIK to document when delinquency spikes, loss events, payment shortfalls (Item 4), or legal proceedings (Item 2) first appeared in public filings. Use accession numbers and EDGAR filing dates to establish the precise timeline of disclosures in rep-and-warranty disputes and servicing failure claims. The 10-D/A amendment trail reveals corrections or restatements.
Ingest the full exhibit set across servicers, trustees, and asset classes to build parsing pipelines that extract standardized fields — pool balance, delinquency buckets, prepayment speeds, tranche factors, credit enhancement levels — from structurally varied servicer report formats. The format shift from plain-text ASCII (2005-2009) to HTML and PDF in later years requires format-aware extraction logic.

What is Form 10-D? Form 10-D is the SEC's periodic distribution report for registered asset-backed securities under Regulation AB. It reports how cash was collected from a securitized pool of financial assets, how collections were allocated through the transaction's payment waterfall, and how much was distributed to each class of securityholders. It replaced the ad hoc use of Form 8-K for ABS periodic reporting when Regulation AB took effect in January 2006.
How often is Form 10-D filed? Filing frequency matches the trust's distribution calendar, which is set by the transaction documents. Most ABS trusts distribute and file monthly. Some CMBS and CLO structures file quarterly. The filing deadline is 15 calendar days after each distribution date.
What is the difference between 10-D and 10-D/A? A 10-D/A is an amendment that corrects or supersedes the original 10-D for the same distribution period and trust. Both versions appear in EDGAR and in this dataset. To get the authoritative version, keep the most recent filing date for a given CIK and period-of-report pair.
How does Form 10-D differ from ABS-EE asset-level data? Form 10-D provides trust-level and tranche-level distribution summaries — aggregate pool performance, waterfall allocations, delinquency rates, and loss statistics. Form ABS-EE provides individual loan-level data in structured XML. ABS-EE was introduced under Regulation AB II (effective November 2016) and covers only new public offerings, while 10-D has been filed since 2005. The two are complementary: ABS-EE for loan-level detail, 10-D for tranche-level distribution mechanics.
Why are some ABS trusts not in this dataset? Only trusts whose securities were registered under the Securities Act of 1933 and subject to Exchange Act reporting file Form 10-D. Privately placed ABS issued under Rule 144A, Regulation D, or other exemptions have no public reporting obligation and are absent. A substantial share of post-2008 ABS issuance is unregistered.
