SEC 8-K filing disclosure categorization. A single 8-K filing can produce multiple rows when it covers multiple disclosure types — each row represents one tagged disclosure within the filing, classified into primary, secondary, and tertiary categories with a supporting text excerpt. The full classification list is available at /stocks/taxonomies/vX/disclosures. Can't find what you're looking for? POST feedback to /feedback, no charge.
