PUDL Raw U.S. Securities and Exchange Commission Form 10-K

The SEC Form 10-K is an annual report required by the U.S. Securities and
Exchange Commission (SEC), that gives a comprehensive summary of a company's financial
performance.

The full contents of the SEC 10-K are available through the SEC's EDGAR
database. PUDL integrates only some of the 10-K metadata and data extracted from the
unstructured Exhibit 21 attachement, which describes the ownershp relationships between
the parent company and its subsidiaries. This data is used to create a linkage between
EIA utilities and SEC reporting companies, to better understand the relationships
between utlities and their affiliates, and the resulting economic and political impacts.

This data was originally downloaded from the SEC and processed using a machine learning
pipeline found here: https://github.com/catalyst-cooperative/mozilla-sec-eia Archived from
https://www.sec.gov/search-filings/edgar-application-programming-interfaces

This archive contains raw input data for the Public Utility Data Liberation (PUDL)
software developed by Catalyst Cooperative. It is
organized into Frictionless
Data Packages. For additional information about this data and PUDL, see the

SEC表格10-K（SEC Form 10-K）是由美国证券交易委员会（U.S. Securities and Exchange Commission，简称SEC）要求提交的年度报告，可全面汇总公司的财务业绩表现。

SEC 10-K的完整内容可通过SEC的EDGAR数据库获取。公共公用事业数据解放（Public Utility Data Liberation，简称PUDL）仅整合了部分10-K元数据，以及从描述母公司与其子公司之间所有权关系的非结构化附件21（Exhibit 21）中提取的数据。此类数据被用于搭建美国能源信息署（Energy Information Administration，简称EIA）旗下公用事业单位与SEC申报公司之间的关联关系，以便更清晰地梳理公用事业单位与其关联机构之间的关联，以及由此产生的经济与政治影响。

本数据集最初从SEC获取，并通过https://github.com/catalyst-cooperative/mozilla-sec-eia 处的机器学习流水线完成处理，其原始存档来源为https://www.sec.gov/search-filings/edgar-application-programming-interfaces。
