h-1 Settlement and regulatory halt requirements for security futures products.
17 C.F.R. § 240.6h-1
in effectEffective: 2024-07-01(a) For the purposes of this section:
(1) Opening price means the price at which a security opened for trading, or a price that fairly reflects the price at which a security opened for trading, during the regular trading session of the national securities exchange or national securities association that lists the security. If the security is not listed on a national securities exchange or a national securities association, then opening price shall mean the price at which a security opened for trading, or a price that fairly reflects the price at which a security opened for trading, on the primary market for the security.
(2) Regular trading session of a security means the normal hours for business of a national securities exchange or national securities association that lists the security.
(3) Regulatory halt means a delay, halt, or suspension in the trading of a security, that is instituted by the national securities exchange or national securities association that lists the security, as a result of:
(i) A determination that there are matters relating to the security or issuer that have not been adequately disclosed to the public, or that there are regulatory problems relating to the security which should be clarified before trading is permitted to continue; or
(ii) The operation of circuit breaker procedures to halt or suspend trading in all equity securities trading on that national securities exchange or national securities association.
(b) Final settlement prices for security futures products. (1) The final settlement price of a cash-settled security futures product must fairly reflect the opening price of the underlying security or securities.
(2) Notwithstanding paragraph (b)(1) of this section, if an opening price for one or more securities underlying a security futures product is not readily available, the final settlement price of the security futures product shall fairly reflect:
(i) The price of the underlying security or securities during the most recent regular trading session for such security or securities; or
(ii) The next available opening price of the underlying security or securities.
(3) Notwithstanding paragraph (b)(1) or (b)(2) of this section, if a clearing agency registered under Section 17A of the Act (15 U.S.C. 78q-1), or exempt from registration pursuant to Section 17A(b)(7) of the Act (15 U.S.C. 78q-1(b)(7)), to which the final settlement price of a security futures product is or would be reported determines, pursuant to its rules, that such final settlement price is not consistent with the protection of investors and the public interest, taking into account such factors as fairness to buyers and sellers of the affected security futures product, the maintenance of a fair and orderly market in such security futures product, and consistency of interpretation and practice, the clearing agency shall have the authority to determine, under its rules, a final settlement price for such security futures product.
(c) Regulatory trading halts. The rules of a national securities exchange or national securities association registered pursuant to Section 15A(a) of the Act (15 U.S.C. 78o-3(a)) that lists or trades one or more security futures products must include the following provisions:
(1) Trading of a security futures product based on a single security shall be halted at all times that a regulatory halt has been instituted for the underlying security; and
(2) Trading of a security futures product based on a narrow-based security index shall be halted at all times that a regulatory halt has been instituted for one or more underlying securities that constitute 50 percent or more of the market capitalization of the narrow-based security index.
(d) The Commission may exempt from the requirements of this section, either unconditionally or on specified terms and conditions, any national securities exchange or national securities association, if the Commission determines that such exemption is necessary or appropriate in the public interest and consistent with the protection of investors. An exemption granted pursuant to this paragraph shall not operate as an exemption from any Commodity Futures Trading Commission rules. Any exemption that may be required from such rules must be obtained separately from the Commodity Futures Trading Commission.
