Rule506bOffering

Git Source

Inherits: Offering, RegDExemption, Whitelist

Implements a Regulation D Rule 506(b) offering. In a 506(b) offering, no general solicitation is permitted, so only pre-approved (whitelisted) investors may participate. Moreover, the offering allows up to 35 non-accredited investors. After the 35 non-accredited participants have been reached, any additional investor must be accredited (i.e. successfully verified).
