On March 25, 2015, the SEC adopted final rules amending Regulation A, referred to now as Regulation A+. These amendments were required by Congress via Title IV of the JOBS Act which was passed some time ago. (we are all still waiting for the Regulation Crowdfunding rules to be finalized).
The general rule is that when a company offers or sells a security, the security must either be registered or an exemption from registration must be relied upon. Regulation A has been on the books for a long long time and has been relied on very little.
Now the SEC has a tough job, its tasked with allowing companies to raise money via offerings of securities but on the other hand it needs to ensure that fraud does not run rampant. These two goals don’t have to be mutually exclusive, but the SEC has generally focused on the latter of the two at the expense of the first.
