Form 40-F/A Filings

SEC Form 40-F/A Filing Deadlines

SEC Form 40-F/A does not have a fixed annual deadline on its own because it is filed only when an amendment to a previously filed Form 40-F is needed. Timing is driven by the nature of the correction or update and any applicable regulatory requirements.

Key Things to Know About Form 40-F/A Filing Rules

• Amendment Purpose Must Be Clear:
  The filing should clearly identify what is being amended and why the amendment is being made.
• Applies Only to Prior Form 40-F Filings:
  Form 40-F/A is used only to amend an existing Form 40-F annual report and is not a standalone annual filing.
• Exhibits and Certifications May Be Refiled:
  Depending on the nature of the amendment, registrants may need to include updated exhibits and refile applicable certifications.
• MJDS Eligibility Still Matters:
  Form 40-F and related amendments are generally available only to eligible Canadian issuers that meet the MJDS requirements and Exchange Act conditions.
• Event-Driven Timing:
  Companies typically file Form 40-F/A in response to specific amendment needs, such as financial statement updates, corrections, or technical compliance requirements.
