US SEC EDGAR Filers

Every filer with the SEC's EDGAR system has a Central Index Key (CIK). This dataset lists the CIKs that have made a filing within the last five years, with their names, former names, tax numbers, jurisdictions of incorporation, addresses and industry sectors.

Filers registered as operating companies, and other filers with company details such as a tax number or a state of incorporation, are listed as companies. Investment funds and filers without company details, most of them individuals, are listed as legal entities.

Directors, officers and owners of more than 10% of a listed company's shares report their holdings and trades on Forms 3, 4 and 5. From the SEC's quarterly extracts of these forms, the dataset links each such insider to the company, with the officer title as stated in the filing and the date of the most recent filing. The forms do not state when a role began or ended.

Companies list their subsidiaries in Exhibit 21 of their annual report on Form 10-K. For the annual reports filed in the last 18 months, the dataset reads the subsidiary tables of these exhibits, including exhibits incorporated by reference from earlier filings, and links each subsidiary to the reporting company. Where the exhibit states an ownership percentage, the link is recorded as ownership; otherwise as control. Subsidiaries listed in prose rather than in a table are not covered, and all subsidiaries are linked directly to the reporting company, even where the exhibit shows intermediate holding companies.
