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 such a manner that:
a. A single authoritative copy of the record or records exists which is unique, identifiable, and, except as otherwise provided in subdivisions d, e, and 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:
(1) Prevent others from adding or changing an identified assignee of the authoritative electronic copy; and (2) Transfer control of the authoritative electronic copy.
4. Subject to subsection 5, a power is exclusive under subdivision c of subsection 3 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 subdivision b of subsection 4 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:
(1) Can exercise the power without exercise of the power by the purchaser; or (2) Is the transferor to the purchaser of an interest in the chattel paper.
6. If a purchaser has the powers specified in subdivision c of subsection 3, 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.
