Assignment of receivables: ensure enforceable interest, free transfer, arms' length pricing and true-sale insolvency remoteness. Assignment requires that receivables generate identifiable cash flows, that the originator hold a valid enforceable interest, that transfers be free of encumbrances and not trigger defaults, that necessary consents be obtained, that set-off be prevented, that pricing be arms' length, and that representations and warranties be honoured; the special purpose entity must hold legally realizable assignments, avoid acquisitions from related parties under common group or control with the trustee, and structure transactions as a genuine true sale to maintain insolvency remoteness.
