On June 3, the SEC adopted rules and form amendments to mandate the electronic filing or submission of certain documents that currently are permitted to be filed or submitted in paper, most notably "glossy" annual reports and Form 144s; and mandate the use of Inline eXtensible Business Reporting Language ("Inline XBRL") for the filing of the financial statements and accompanying schedules to the financial statements required by Form 11-K. The new rules for annual reports and most of the other filings impacted will go into effect in approximately 6 months, while the new rules for Form 144 will go into effect 6 months after an updated EDGAR filer manual is published (expected in September; so presumably the new Form 144 rules will go into effect sometime around March 2023). In addition, once in effect, the current SEC guidance allowing website posting of annual reports in lieu of filing with the SEC will be withdrawn (though of course companies can continue to post them on their websites in addition to the EDGAR filings).
