This section provides a non-exclusive definition of circumstances in which a person has a duty of trust or confidence for purposes of the “misappropriation” theory of insider trading under Section 10(b) of the Act and Rule 10b-5. The law of insider trading is otherwise defined by judicial opinions construing Rule 10b-5, and Rule 10b5-2 does not modify the scope of insider trading law in any other respect.

(3) Whenever a person receives or obtains material nonpublic information from his or her spouse, parent, child, or sibling; provided, however, that the person receiving or obtaining the information may demonstrate that no duty of trust or confidence existed with respect to the information, by establishing that he or she neither knew nor reasonably should have known that the person who was the source of the information expected that the person would keep the information confidential, because of the parties' history, pattern, or practice of sharing and maintaining confidences, and because there was no agreement or understanding to maintain the confidentiality of the information.
