In order to begin the qualification process for an offering under Reg. A, both Tier 1 and Tier 2 Reg. A issuers are required to file a Form 1-A (https://www.sec.gov/about/forms/form1-a.pdf)with the SEC. The Form 1-A may be filed confidentially as long as it is publicly filed with the SEC at least 21 days prior to qualification of the Reg. A offering. If the SEC has any comments, they will submit them to the issuer in a comment letter and the issuer will have the opportunity to respond. Under Reg. A, the issuer response to each comment letter received from the SEC must be filed. Once the Reg. A offering has been qualified, both Tier 1 and Tier 2 issuers are obligated to file an exit report on Form 1-Z. (https://www.sec.gov/files/form1-z.pdf)In addition, Tier 2 issuers under Reg. A are also required to file annual reports on Form 1-K, (https://www.sec.gov/files/form1-k.pdf)semiannual reports on Form 1-SA,(https://www.sec.gov/files/form1-sa.pdf) and current reports on Form 1-U.(https://www.sec.gov/files/form1-u.pdf)
