Page 16 October 2008 The new Bridge: Changing your perception Daytime Bridge : an effective infrastructure for secondary market settlement Settlement efficiency rates over bridge are now equal to internal transactions Quality of ICSD settlement engines and number of instructions exchanges ensures that the most complex chains of transactions are always resolved To ensure that the Bridge is sufficiently robust to support evolving market needs, we need to maintain the pace of progress Joint effort with Euroclear to make continuous improvements to the infrastructure so we eliminate all bottlenecks Push for full interoperability Interoperability Future aim to maximise same-day financing and settlement possibilities and to introduce interoperability between the triparty repo systems of the ICSDs
