Form 497K Filings

What Is SEC Form 497K?

SEC Form 497K is a summary prospectus filing submitted under Securities Act Rule 497(k) by certain open-end management investment companies. It is used to file a concise summary prospectus that highlights key fund information while directing investors to more detailed statutory disclosures available through the SEC’s EDGAR system.

This form is typically filed when a fund provides an updated annual summary prospectus, introduces a new summary prospectus, or revises summary disclosures due to changes in its statutory prospectus or statement of additional information. Because the summary prospectus is designed to be read alongside more comprehensive disclosure materials, it includes references to incorporated documents and instructions for accessing the full prospectus online or upon request, supporting standardized and compliant investor disclosure. To review current and historical filings, users often rely on tools that can help search SEC filings by form type and issuer.

Key elements typically found in SEC Form 497K include:

• Fund name and share class identifiers
• Summary prospectus date and effective or revision context
• Key fund information, such as fees, expenses, principal strategies, and risks
• Performance summary and benchmark disclosure (as applicable)
• Purchase and sale details, tax information, and payments to intermediaries
• Instructions for accessing the full statutory prospectus and related documents

SEC Form 497K Filing Deadlines

SEC Form 497K does not have a single fixed statutory “deadline” like event-driven Exchange Act filings. Instead, it is filed in connection with a fund’s prospectus delivery and update cycle, including annual updates and other times when summary prospectus disclosure is revised. Filing timing is generally tied to when updated summary materials are intended to be used and delivered to investors.

Key Things to Know About Form 497K Filing Rules

• Summary Prospectus Filing Format:
  Form 497K is used to file summary prospectuses that provide condensed fund information and reference more complete statutory disclosure materials.
• Filed in Connection With Prospectus Updates:
  Many Form 497K filings are associated with annual prospectus updates, revisions, or other disclosure changes that affect how summary information is presented.
• EDGAR Availability Is Central:
  Filers typically ensure that the summary prospectus and referenced statutory materials are accessible through EDGAR and other permitted delivery methods.
• Not an Exchange Act Periodic Report:
  Form 497K is a Securities Act/Investment Company Act disclosure delivery filing and is not a periodic operating report like Forms 10-K or 10-Q.
• Used Across Eligible Open-End Funds:
  It is commonly used by mutual funds and similar eligible funds that utilize the summary prospectus framework, with content tailored to the fund’s disclosures and share classes.
