- ...
- Academic Material Contracts Corpora (MCC), such as:
- Counter-Examples:
- General Legal Corpus, which contains broader legal documents beyond material contracts and lacks material contract specific metadata.
- Contract Template Database, which stores contract templates rather than executed material contracts and does not reflect material contract actual usage.
- Contract Management System, which focuses on contract lifecycle management rather than material contract research and material contract analysis.
- Legal Precedent Database, which collects court decisions rather than material contracts and serves legal precedent research rather than material contract study.
- Private Contract Archive, which contains proprietary contracts not filed with regulatory agencies and lacks the material contract public accessibility that characterizes Material Contracts Corpus (MCC).

- Question: What is a Material Contracts Corpus and how is it used in legal NLP applications?
- Answer: A Material Contracts Corpus (MCC) is a large collection of significant legal contracts, typically those material contracts that companies are required to disclose in regulatory filings. MCCs serve as foundational resources for legal language analysis, legal AI development, and empirical legal research.
- Definition and Context:
- Core Concept: A Material Contracts Corpus refers to a large collection of significant legal contracts, typically those "material" contracts that companies are required to disclose in regulatory filings.
- Examples: The Stanford Material Contracts Corpus is a publicly available dataset of over one million contracts filed by public companies with the U.S. Securities and Exchange Commission (SEC) between 2000 and 2023.
- Purposes: MCCs are compiled to facilitate empirical research on contract design and language patterns and to support the development of AI-based legal tools.
- Material Contract Definition: Under SEC rules, a material contract is generally defined as an agreement "not made in the ordinary course of business" that is material to the company (the registrant).
- Material Contract Examples: Material contracts typically include merger and acquisition agreements, executive employment agreements, high-value licensing or joint venture agreements, major financing or loan agreements, and other contracts that a reasonable investor would consider important.
- Filing Requirements: Public companies must file these material contracts as exhibits to their disclosure forms (such as annual 10-K reports, quarterly 10-Q reports, current reports on 8-K, or registration statements).
- Structure and Contents:
- Document Collection: A typical MCC is structured as a collection of individual contract documents along with metadata about each document.
- Document Formats: Each contract in the corpus is usually stored in a text-based format (e.g., HTML or plain text extracted from filings) for easy processing.
- Document Types: The corpus includes various contract types, including:
- Merger & Acquisition Agreements: Definitive agreements for mergers, acquisitions, asset purchases, or similar major transactions.
- Employment and Compensation Agreements: Contracts between the company and key executives or directors.
- Licensing and Joint Venture Agreements: Contracts granting licenses to important technology or forming joint ventures/strategic partnerships.
- Financing and Security Agreements: Major loan agreements, credit facilities, indentures, guarantees, or other debt/equity financing contracts.
- Lease Agreements: Significant property or equipment leases entered by the company.
- Shareholder or Governance Agreements: Agreements related to corporate governance or shareholder rights.
- Metadata and Annotations: An MCC often includes metadata such as filing source, date of filing, names of parties, and agreement type.
- Classification System: Many MCCs use NLP models to automatically classify each contract's agreement type, improving searchability and analysis.
- Common Use Cases:
- Empirical Legal Research: Legal scholars and economists use contract corpora to examine how contracts are designed and how contract language evolves over time.
- Contract Drafting and Clause Libraries: Lawyers and contract drafters can search the corpus to see how specific clauses are worded in industry-standard agreements.
- Automated Contract Review: MCCs provide training data for AI models that can review and analyze contracts, flagging "red flag" provisions for lawyers.
- Contract Classification and Organization: Natural language processing on an MCC allows automated classification of contracts by type or attributes.
- Training Legal Language Models: Large contract corpora are used to pre-train or fine-tune language models specialized in legal text.
- Benchmarking and Evaluation: MCCs serve as benchmarks to evaluate NLP algorithms on legal texts.
- Public MCC Datasets and Tools:
- Stanford Material Contracts Corpus: One of the largest and most comprehensive MCCs, containing about 1.25 million filed contracts, consolidated into ~1.04 million unique contracts after de-duplication.
- CUAD (Contract Understanding Atticus Dataset): A dataset of over 500 contracts that have been carefully annotated by legal experts to mark 41 categories of important clauses.
- EDGAR-Based Contract Datasets: Various efforts to harvest contract data from the SEC's EDGAR system.
- M&A Contract Corpus: A specialized corpus focusing on definitive merger agreements for large M&A deals, containing 7,929 merger agreements filed with the SEC between 2000 and 2020.
- Example Projects:
- Academic Research on Contract Language: Researchers have analyzed legal language patterns, the evolution of boilerplate terms, and trends in contract length and complexity.
- Legal AI Development: Projects like the CUAD dataset have catalyzed the development of AI models that can identify key clauses in contracts.
- Industry Applications: Companies like JPMorgan Chase have developed tools such as COIN (Contract Intelligence) that can interpret and extract key data from loan contracts.
- Public Policy Initiatives: MCCs enable transparency by allowing analysis of how businesses operate through their contractual arrangements.

- ABSTRACT: This paper introduces the Material Contracts Corpus (MCC), a publicly available dataset comprising over one million contracts filed by public companies with the U.S. Securities and Exchange Commission (SEC) between 2000 and 2023. The MCC facilitates empirical research on contract design and legal language, and supports the development of AI-based legal tools. Contracts in the corpus are categorized by agreement type and linked to specific parties using machine learning and natural language processing techniques, including a fine-tuned LLaMA-2 model for contract classification. The MCC further provides metadata such as filing form, document format, and amendment status. We document trends in contractual language, length, and complexity over time, and highlight the dominance of employment and security agreements in SEC filings.
