17 CFR § 243.101 - Definitions.
(a) Intentional. A selective disclosure of material nonpublic information is “intentional” when the person making the disclosure either knows, or is reckless in not knowing, that the information he or she is communicating is both material and nonpublic.
(b) Issuer. An “issuer” subject to this regulation is one that has a class of securities registered under Section 12 of the Securities Exchange Act of 1934 (15 U.S.C. 78l), or is required to file reports under Section 15(d) of the Securities Exchange Act of 1934 (15 U.S.C. 78o(d)), including any closed-end investment company (as defined in Section 5(a)(2) of the Investment Company Act of 1940) (15 U.S.C. 80a-5(a)(2)), but not including any other investment company or any foreign government or foreign private issuer, as those terms are defined in Rule 405 under the Securities Act (§ 230.405 of this chapter).
(c) Person acting on behalf of an issuer. “Person acting on behalf of an issuer” means any senior official of the issuer (or, in the case of a closed-end investment company, a senior official of the issuer's investment adviser), or any other officer, employee, or agent of an issuer who regularly communicates with any person described in § 243.100(b)(1)(i), (ii), or (iii), or with holders of the issuer's securities. An officer, director, employee, or agent of an issuer who discloses material nonpublic information in breach of a duty of trust or confidence to the issuer shall not be considered to be acting on behalf of the issuer.
(d) Promptly. “Promptly” means as soon as reasonably practicable (but in no event after the later of 24 hours or the commencement of the next day's trading on the New York Stock Exchange) after a senior official of the issuer (or, in the case of a closed-end investment company, a senior official of the issuer's investment adviser) learns that there has been a non-intentional disclosure by the issuer or person acting on behalf of the issuer of information that the senior official knows, or is reckless in not knowing, is both material and nonpublic.
(e) Public disclosure.
(1) Except as provided in paragraph (e)(2) of this section, an issuer shall make the “public disclosure” of information required by § 243.100(a) by furnishing to or filing with the Commission a Form 8-K (17 CFR 249.308) disclosing that information.
(2) An issuer shall be exempt from the requirement to furnish or file a Form 8-K if it instead disseminates the information through another method (or combination of methods) of disclosure that is reasonably designed to provide broad, non-exclusionary distribution of the information to the public.
(f) Senior official. “Senior official” means any director, executive officer (as defined in § 240.3b-7 of this chapter), investor relations or public relations officer, or other person with similar functions.
(g) Securities offering. For purposes of § 243.100(b)(2)(iv):
(1) Underwritten offerings. A securities offering that is underwritten commences when the issuer reaches an understanding with the broker-dealer that is to act as managing underwriter and continues until the later of the end of the period during which a dealer must deliver a prospectus or the sale of the securities (unless the offering is sooner terminated);
(2) Non-underwritten offerings. A securities offering that is not underwritten:
(i) If covered by Rule 415(a)(1)(x) (§ 230.415(a)(1)(x) of this chapter), commences when the issuer makes its first bona fide offer in a takedown of securities and continues until the later of the end of the period during which each dealer must deliver a prospectus or the sale of the securities in that takedown (unless the takedown is sooner terminated);
(ii) If a business combination as defined in Rule 165(f)(1) (§ 230.165(f)(1) of this chapter), commences when the first public announcement of the transaction is made and continues until the completion of the vote or the expiration of the tender offer, as applicable (unless the transaction is sooner terminated);
(iii) If an offering other than those specified in paragraphs (a) and (b) of this section, commences when the issuer files a registration statement and continues until the later of the end of the period during which each dealer must deliver a prospectus or the sale of the securities (unless the offering is sooner terminated).
