The perfection and priority rules of this Article are designed to facilitate current secured financing arrangements for securities firms as well as to provide sufficient flexibility to accommodate new arrangements that develop in the future. Hard pledge arrangements are covered by the concept of control. See Sections 9-314 [Maine cite section 9-1314], 9-106 [Maine cite section 9-1106], 8-106. Non-control secured financing arrangements for securities firms are covered by the automatic perfection rule of paragraph (10) [Maine cite paragraph (j)]. Before the 1994 revision of Articles 8 and 9, agreement to pledge arrangements could be implemented under a provision that a security interest in securities given for new value under a written security agreement was perfected without filing or possession for a period of 21 days. Although the security interests were temporary in legal theory, the financing arrangements could, in practice, be continued indefinitely by rolling over the loans at least every 21 days. Accordingly, a knowledgeable creditor of a securities firm realizes that the firm's securities may be subject to security interests that are not discoverable from any public records. The automatic- perfection rule of paragraph (10) [Maine cite paragraph (j)] makes it unnecessary to engage in the purely formal practice of rolling over these arrangements every 21 days.

In some circumstances, a clearing corporation may be the debtor in a secured financing arrangement. For example, a clearing corporation that settles delivery-versus-payment transactions among its participants on a net, same-day basis relies on timely payments from all participants with net obligations due to the system. If a participant that is a net debtor were to default on its payment obligation, the clearing corporation would not receive some of the funds needed to settle with participants that are net creditors to the system. To complete end-of-day settlement after a payment default by a participant, a clearing corporation that settles on a net, same- day basis may need to draw on credit lines and pledge securities of the defaulting participant or other securities pledged by participants in the clearing corporation to secure
