A number of rights may be assigned without individual specification, provided such rights can be identified as rights to which the assignment relates at the time of the assignment or when they come into existence.
Rights are often assigned as a bundle or in bulk. A company may for instance assign all its receivables to a factoring company. In practice it would be excessively burdensome to require individual specification of each assigned right, but the global identification of the rights assigned as a bundle must be such as to permit the recognition of each right concerned as part of the assignment.
In the case of existing rights, such recognition must be possible at the time of the assignment. If future rights are included in the bundle, in accordance with Article 9.1.5 identification must be possible when the rights come into existence.
Retailer A assigns all its receivables to factor B. There are thousands of existing and/or future rights. The assignment does not require the specification of each single claim. Later, B gives notice of the assignment to the obligor of a specific receivable. B must be able to demonstrate the inclusion of that receivable in the bundle either at the time of the assignment, or, in the case of a right which did not exist yet at that time, when the right came into existence.
