§ 354.3 Law governing other interests. ( a ) To the extent not inconsistent with the regulations in this part, the law (not including the conflict-of-law rules) of a Securities Intermediary's jurisdiction governs: ( 1 ) The acquisition of a Security Entitlement from the Securities Intermediary;
( 2 ) The rights and duties of the Securities Intermediary and Entitlement Holder arising out of a Security Entitlement;
( 3 ) Whether the Securities Intermediary owes any duties to an adverse claimant to a Security Entitlement;
( 4 ) Whether an Adverse Claim can be asserted against a Person who acquires a Security Entitlement from the Securities Intermediary or a Person who purchases a Security Entitlement or interest therein from an Entitlement Holder; and
( 5 ) Except as otherwise provided in paragraph (c) of this section, the perfection, effect of perfection or non-perfection and priority of a security interest in a Security Entitlement.
( b ) The following rules determine a “Securities Intermediary's jurisdiction” for purposes of this section: ( 1 ) If an agreement between the Securities Intermediary and its Entitlement Holder specifies that it is governed by the law of a particular jurisdiction, that jurisdiction is the Securities Intermediary's jurisdiction.
( 2 ) If an agreement between the Securities Intermediary and its Entitlement Holder does not specify the governing law as provided in paragraph (b)(1) of this section, but expressly specifies that the securities account is maintained at an office in a particular jurisdiction, that jurisdiction is the Securities Intermediary's jurisdiction.
( 3 ) If an agreement between the Securities Intermediary and its Entitlement Holder does not specify a jurisdiction as provided in paragraph (b)(1) or (b)(2) of this section, the Securities Intermediary's jurisdiction is the jurisdiction in which is located the office identified in an account statement as the office serving the Entitlement Holder's account.
( 4 ) If an agreement between the Securities Intermediary and its Entitlement Holder does not specify a jurisdiction as provided in paragraph (b)(1) or (b)(2) of this section and an account statement does not identify an office serving the Entitlement Holder's account as provided in paragraph (b)(3) of this section, the Securities Intermediary's jurisdiction is the jurisdiction in which is located the chief executive office of the Securities Intermediary.
( c ) Notwithstanding the general rule in paragraph (a)(5) of this section, the law (but not the conflict-of-law rules) of the jurisdiction in which the Person creating a security interest is located governs whether and how the security interest may be perfected automatically or by filing a financing statement.
( d ) If the jurisdiction specified in paragraph (b) of this section is a State that has not adopted Revised Article 8 (incorporated by reference, see § 354.1), then the law for the matters specified in paragraph (a) of this section shall be the law of that State as though Revised Article 8 had been adopted by that State. For purposes of the application of the matters specified in paragraph (a) of this section, the Federal Reserve Bank maintaining the Participant's Securities Account is a clearing corporation, and the Participant's interest in a Book-entry Security is a Security Entitlement.
