  <cov:taStatementAboutAmendment>This filing is a material amendment to Part III, Items 11 and 14, that will enable Subscribers to limit their counterparties via "hosted pool" capability within the MOC Crossing Session, and cross orders at a specific time prior to the relevant exchange's cut off time for MOC orders. The changes herein impact all Subscriber orders within an MOC Crossing Session, and how orders routed by Instinet algorithm or SOR to the MOC Cross interact with the orders of other Subscribers. They apply to all Subscribers and the broker-dealer operator. </cov:taStatementAboutAmendment>
