Excerpt from SEC.gov:
Rule 506 of Regulation D provides two distinct exemptions from registration for companies when they offer and sell securities. Companies relying on the Rule 506 exemptions can raise an unlimited amount of money.
Under Rule 506(b), a “safe harbor” under Section 4(a)(2) of the Securities Act, a company can be assured it is within the Section 4(a)(2) exemption by satisfying certain requirements, including the following:
- The company cannot use general solicitation or advertising to market the securities.
- The company may sell its securities to an unlimited number of "accredited investors" and up to 35 other purchasers. All non-accredited investors, either alone or with a purchaser representative, must be sophisticated—that is, they must have sufficient knowledge and experience in financial and business matters to make them capable of evaluating the merits and risks of the prospective investment.
- Companies must decide what information to give to accredited investors, so long as it does not violate the antifraud prohibitions of the federal securities laws. This means that any information a company provides to investors must be free from false or misleading statements. Similarly, a company should not exclude any information if the omission makes what is provided to investors false or misleading. Companies must give non-accredited investors disclosure documents that are generally the same as those used in Regulation A or registered offerings, including financial statements, which in some cases may need to be certified or audited by an accountant. If a company provides information to accredited investors, it must make this information available to non-accredited investors as well.
- The company must be available to answer questions by prospective purchasers.
