3 Page 3 Trading Environment Characteristics Anonymity Liquidity Transparency 4 Brokers Broker Were They Efficient? Human factor Limited network of contacts Largest firms control the inventory Regional broker/dealers not well serviced Difficult to unwind odd-lot positions Phantom trades Buy-side firms are not a part of the equation 5

4 Page 4 Where Are We Now? Automated Trading Systems (ATS) Eliminates the Human Factor Buy-side is involved More regional bank and foreign institution participation Internet A border-less enterprise All of which creates better Liquidity and more Transparency in an Anonymous environment. 6 Six Drivers for Change Institutional and Retail customers Brick and mortar sell-side institutions Traditional buy-side firms Broker s brokers Regulatory Entrepreneurs 7

5 Page 5 Challenges Existing legacy systems and newer ATS s will need to handle anticipated increases in trade volume implied by the development of STP. Fixed Income securities can have complex structures. Trading systems will need to incorporate proper analytics to calculate various essential data. There are many types of Fixed Income securities which trade in different ways. Standardized trading methodologies will need to be applied. Security information repositories will need to be large enough to hold data on millions of securities. Present front-end interfaces are no more than client/server versions of legacy systems. Back-office systems are antiquated. It may not be feasible to integrate them if they cannot support the new economy business. The new Fixed Income market of tomorrow may require an Application Program Interface (API) to a single Fixed Income exchange. T+1 must be incorporated into new technology. 8 Architecture Development Methodology
