Amending the Form from S-1 to S-1/A
The form is sometimes amended as material information changes or general market conditions cause a delay in the offering. In this case, the issuer needs to file Form S-1/A. The Securities Exchange Act of 1933, often referred to as the truth in securities law, requires that these registration forms are filed to disclose important information upon registration of a company's securities. This helps the SEC achieve the objectives of this act: requiring investors to receive significant information regarding securities offered and prohibit fraud in the sale of the offered securities.
