Assets in possession on a 'sale or return' basis (with such an option included in the contract) are treated as accounts receivable from the vendor and as such would be offset against the related accounts payable to the vendor. If these accounts payable have been settled, the assets must attract a RW based on rating of the vendor (100% in case of unrated), subject to (a) the availability of documentation evidencing such an arrangement with the vendor, and (b) the period for returning the assets to the vendor not having been exceeded. If the above conditions are not satisfied, capital charge will be provided as per Paragraph CA-3.2.20.
