In June 2007, the SEC proposed amendments mandating the electronic filing of Form D together with substantive revisions to the form. In February of this year, those amendments were adopted almost entirely as proposed. Although these final rules embody both substantive and procedural changes, Form D retains its primary purpose as an initial notice form. On September 15, 2008, the SEC's Form D electronic filing system went online. From that date until March 15, 2009, companies have the option of filing Form D information electronically through the EDGAR system or using a paper Form D.
