Confidential submission process for emerging growth companies

Pursuant to what is colloquially known as the “IPO On-Ramp,” issuers that are “emerging growth companies” may submit registration statements to the SEC on a confidential basis prior to formally and publicly filing the registration statements. Some additional clarification on these matters was issued as follows:

- The method of submitting registration statements for confidential submission has been established. Since the SEC’s electronic system, known as EDGAR, does not have a means for confidential submission, all such submissions must be made on paper. In further oral guidance, the staff of the SEC has stated that once a confidential submission has been made, the SEC will call the issuer to let it know to whom the matter has been assigned. As of April 11, 2012, the SEC had received two confidential submissions.
