Form 13F-HR/A Filings

What Is SEC Form 13F-HR/A?

SEC Form 13F-HR/A is an amendment to Form 13F-HR, filed by institutional investment managers to update or correct previously reported quarterly holdings information required under Section 13(f) of the Securities Exchange Act of 1934 and the rules thereunder.

This form is typically filed when a manager discovers an error, omission, or reporting issue in an earlier submission and needs to restate or revise the previously reported holdings information.

Form 13F-HR/A helps maintain transparency and accuracy in public reporting of institutional investment positions by providing an updated version of a previously filed report, and it is commonly used alongside related filing types listed in the SEC forms and filings directory.

Key elements typically found in SEC Form 13F-HR/A include:

• Name of the institutional investment manager and address
• Form 13F file number (and other identifying information, if applicable)
• Reporting period (calendar quarter ended) and amendment indicator
• Amendment type information (e.g., restatement and/or new holdings entries)
• Updated holdings information and related cover page details
• Revised information table data included with the amended report

SEC Form 13F-HR/A Filing Deadlines

SEC Form 13F-HR/A does not have a single fixed filing deadline like the initial Form 13F-HR. Instead, it is filed on an as-needed basis when a manager must correct, restate, or update a previously filed report, including amendments related to confidential treatment timing requirements described in the Form 13F instructions.

Key Things to Know About Form 13F-HR/A Filing Rules

• Amendment Purpose: Form 13F-HR/A is used to correct, restate, or update information previously reported on a Form 13F-HR for a calendar quarter, rather than to make a routine initial quarterly submission.
• Restatement and New Holdings Entries: The amendment can reflect a restatement of previously reported information and/or include new holdings entries, depending on the nature of the correction and how the amendment is marked on the cover page.
• Original 13F Deadline Still Applies: Filing Form 13F-HR/A does not replace the obligation to file the initial Form 13F-HR within the required timeframe after quarter-end; the amendment is filed only when an update is necessary.
• Confidential Treatment Timing Considerations: If a manager has requested confidential treatment for certain holdings information, an amendment may be required upon denial of the request or upon expiration of the relevant confidential treatment period.
• Related 13F Amendment Filings: Managers that file a notice report and later need to correct it may use related amendment forms such as Form 13F-NT/A, depending on the filer’s reporting approach for the period.
