Form F-X/A Filings

What Is SEC Form F-X/A?

SEC Form F-X/A is an important filing used to amend a previously submitted Form F-X, which appoints a U.S. agent for service of process and includes related undertakings for certain foreign issuers and other foreign filers. It is typically filed when the filer needs to update information such as the agent’s name or address, or otherwise amend the original filing associated with a related SEC form or schedule.

This form is typically filed on an event-driven basis rather than on a fixed periodic schedule. The original Form F-X is required in connection with certain filings, including Forms F-8, F-10, F-80, 40-F, certain Canadian tender offer schedules, and some Regulation A and trustee-related filings, and the amendment is used when previously reported agent information changes. Filers researching related foreign filing activity may also review the full SEC issuer list for broader issuer context.

Form F-X/A ensures transparency by formally notifying the SEC of updates to the filer’s appointment of agent for service of process and undertaking. While it does not register securities or serve as a stand-alone offering document, it helps keep the record current for foreign filing obligations connected to other SEC submissions. For additional context around related cross-border and offering activity, filers may also follow broader filing insights and certain private offerings data sets.

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

• Name of the issuer or person filing
• Identification that the filing is an amended filing
• Reference to the related SEC filing in conjunction with which Form F-X was filed
• Jurisdiction of incorporation or organization and principal place of business
• Name and address of the U.S. agent for service of process
• Updated undertaking regarding changes to the agent’s name or address

SEC Form F-X/A Filing Deadlines

SEC Form F-X/A has event-driven timing requirements that filers must follow when information in a previously filed Form F-X changes. These timing considerations are important to maintain accurate records regarding the filer’s U.S. agent for service of process and related undertakings.
