Instruction to paragraph (a): With respect to any beneficial owner of 20 percent or more of the issuer's outstanding voting equity securities, calculated on the basis of voting power, the issuer is required to determine whether a disqualifying event has occurred only as of the time of filing of the offering statement and not from the time of such sale.
Note to paragraph (b)(4). An issuer will not be able to establish that it has exercised reasonable care unless it has made, in light of the circumstances, factual inquiry into whether any disqualifications exist. The nature and scope of the factual inquiry will vary based on the facts and circumstances concerning, among other things, the issuer and the other offering participants.
