Cal. Com. Code § 15103 — EFFECTIVE DATE AND TRANSITION PROVISIONS

The owner of an interest (other than a security interest) in an uncertificated security (paragraph (b) of subdivision (1) of Section 8102) whose interest was acquired prior to January 1, 1985, or was acquired after January 1, 1985, in an uncertificated security issued in respect of a security in which the owner had such an interest, shall not be required to take any action under Section 8313 or otherwise to preserve or protect that ownership interest, which shall remain effective and enforceable to the same extent it was prior to January 1, 1985, in the absence of that action. However, if a security interest first attaches to the security or any other interest in the security first becomes effective after that date, the provisions of Division 8 (commencing with Section 8101) as revised shall govern the rights and obligations of all persons with respect to those interests. Except as otherwise provided in this division, the rights and obligations of all persons with respect to uncertificated securities issued prior to January 1, 1985, shall be governed by Division 8 (commencing with Section 8101) as revised by Chapter 927 of the Statutes of 1984. All references in this section to Division 8 (commencing with Section 8101) or a section thereof are references to Division 8 (commencing with Section 8101) as revised by Chapter 927 of the Statutes of 1984.
