Page 7 PRIVATE AND CONFIDENTIAL Overall Risk Average Rating - ACSDA Average Rating – EU/EEA Average Rating – Eurasia Average Rating – Asia Pacific Average Rating – Africa Average Rating – Middle East Key Issues The Overall Risk rating is a weighted average of the other six risk types. The risks are divided into 3 groups; Settlement, CSD Operation and Asset Servicing and each group is given equal weighting. Settlement group comprises of Asset Commitment, Liquidity and Counterparty Risk. CSD Operation comprises Financial and Operational Risks. The weights can vary depending on the degree to which the CSD undertakes Asset Servicing activities. The weights will need to be revised with the inclusion of Asset Safety and Governance & Transparency Risks. AAA AA+ AA AA- A+ A A- BBB BB B CCC CC C Rating Risk Weights

Page 9 PRIVATE AND CONFIDENTIAL Asset Commitment Risk Risk Factors Asset commitment risk is a quantitative measurement of the asset commitment period for every type of settlement process Most depositories have different ways of settling transactions, which could depend on place of trade execution (e.g. on-exchange or OTC), different markets, choice of processing cycle (Batch or real- time) or even asset class The weighting given to each process is determined by the value percentage of transactions going through each settlement process.

Page 10 PRIVATE AND CONFIDENTIAL Liquidity Risk AAA AA+ AA AA- A+ A A- BBB BB B CCC CC C Rating Risk Factors The settlement processing model adopted by a CSD usually follows either Gross or Net settlement. The number of settlement cycles and the netting efficiency of the processing is a key component in assessing the effectiveness of the settlement model. The appropriate fails management regime operated by the CSD hinges around the range and timing of approaches used, factored by the actual settlement rate The ability of clients to access credit facilities is critical to their ability to provide timely funding of a trade Securities borrowing and lending (SBL) provides for securities shortfalls. Matching processes in the market for CSD settled transactions assess both client side matching and market side matching and are given equal weighting. Also take into account the registration arrangement and the proportion of securities on issue held within the CSD.

Page 11 PRIVATE AND CONFIDENTIAL Counterparty Risk AAA AA+ AA AA- A+ A A- BBB BB B CCC CC C Rating Risk Factors The most important principle to control counterparty risk is the use of Delivery versus Payment (DVP) settlement; which is the interdependent transfer of securities against cash. Participants should have minimum capital requirement specified and appropriate technical resources. Some surveillance should be undertaken on participants activities and their exposure levels. The ability to manage a default is assessed in terms of the structure and financial resources available to guarantee all open obligations of the party that has defaulted (a guarantee fund). Where a CCP is available, these are assessed as the ultimate counterparty in a market Average Rating - ACSDA Average Rating – EU/EEA Average Rating – Eurasia Average Rating – Asia Pacific Average Rating – Africa Average Rating – Middle East

There are two key focal points to this risk – the first involves the collection and dissemination of information and the second is the receipt and execution of instructions. There are other areas such as proxy voting and other related services eg tax services that are also included where these are (rarely) pursued by the CSD.

Profitability and revenue generation is assessed over a 5 year period. The strength and quality of ownership of the CSD becomes increasingly important were the CSD to be under duress. The standard of liability a depository assumes in relation to any claims against it by participants who may have suffered losses due to the actions or omissions of the CSD. The primary way a CSD can cover any claims is through acquiring adequate insurance. Another avenue of funds is through secured credit lines Also examine outstanding investments by the CSD in infrastructure (building, computer systems etc.)

Documented procedures are required for all processes. All operations including IT operations should be subject to both internal and external audit. Appropriate DRP and BCP arrangements that have been fully and regularly tested are essential. Automation of processes reduces the risk of manual errors. Reporting arrangements to clients is also taken into account. Staff training helps manage risks when manual intervention is required.
