(1) A purchaser has control of an authoritative electronic copy of a record evidencing chattel paper if a system employed for evidencing the assignment of interests in the chattel paper reliably establishes the purchaser as the person to which the authoritative electronic copy was assigned.
(2) A system satisfies subsection (1) if the record or records evidencing the chattel paper are created, stored, and assigned in a manner that:
(a) a single authoritative copy of the record or records exists which is unique, identifiable, and, except as otherwise provided in subsections (2)(d), (2)(e), and (2)(f), unalterable;
(b) the authoritative copy identifies the purchaser as the assignee of the record or records;
(c) the authoritative copy is communicated to and maintained by the purchaser or its designated custodian;
(d) copies or amendments that add or change an identified assignee of the authoritative copy can be made only with the consent of the purchaser;
(e) each copy of the authoritative copy and any copy of a copy is readily identifiable as a copy that is not the authoritative copy; and
(f) any amendment of the authoritative copy is readily identifiable as authorized or unauthorized.
(3) A system satisfies subsection (1), and a purchaser has control of an authoritative electronic copy of a record evidencing chattel paper, if the electronic copy, a record attached to or logically associated with the electronic copy, or a system in which the electronic copy is recorded:
(a) enables the purchaser readily to identify each electronic copy as either an authoritative copy or a nonauthoritative copy;
(b) enables the purchaser readily to identify itself in any way, including by name, identifying number, cryptographic key, office, or account number, as the assignee of the authoritative electronic copy; and
(c) gives the purchaser exclusive power, subject to subsection (4), to:
(i) prevent others from adding or changing an identified assignee of the authoritative electronic copy; and
(ii) transfer control of the authoritative electronic copy.
(4) Subject to subsection (5), a power is exclusive under subsections (3)(c)(i) and (3)(c)(ii) even if:
(a) the authoritative electronic copy, a record attached to or logically associated with the authoritative electronic copy, or a system in which the authoritative electronic copy is recorded limits the use of the authoritative electronic copy or has a protocol programmed to cause a change, including a transfer or loss of control; or
(b) the power is shared with another person.
(5) A power of a purchaser is not shared with another person under subsection (4)(b) and the purchaser's power is not exclusive if:
(a) the purchaser can exercise the power only if the power also is exercised by the other person; and
(b) the other person:
(i) can exercise the power without exercise of the power by the purchaser; or
(ii) is the transferor to the purchaser of an interest in the chattel paper.
(6) If a purchaser has the powers specified in subsections (3)(c)(i) and (3)(c)(ii), the powers are presumed to be exclusive.
(7) A purchaser has control of an authoritative electronic copy of a record evidencing chattel paper if another person, other than the transferor to the purchaser of an interest in the chattel paper:
(a) has control of the authoritative electronic copy and acknowledges that it has control on behalf of the purchaser; or
(b) obtains control of the authoritative electronic copy after having acknowledged that it will obtain control of the electronic copy on behalf of the purchaser.
