On February 20th, the SEC reminded filers to confirm that internal links in their EDGAR filings are working properly before to submitting the filings on EDGAR. Electronic filers may include links to different sections within a single HTML document, such as, in exhibits filed under Item 601 of Regulation S–K. Filers should be mindful that incorrect internal links will result in errors surrounding those links when the filings are disseminated.
The validation tools in the GoFiler Suite will determine if hyperlinks in HTML and iXBRL filings are valid. We encourage users to validate their documents using these tools at least once before submitting them. Contact support with any questions.
