Assessing & Measuring Operational Risk Why COSO is Inappropriate ISDA PRMIA London, United Kingdom January 18, 2005 Ali Samad-Khan President, OpRisk Advisory LLC ali.samad-khan@opriskadvisory.com www.opriskadvisory.com Agenda I II III IV V VI VII Introduction Definition and Categorization COSO Based Risk Assessment Integrated Risk Measurement and Management Alternative Approaches to Risk Assessment Control Assessment Summary & Conclusions Copyright © 2004, OpRisk Advisory LLC. All rights reserved. INTRODUCTION When considering risk and control assessment, what are the priorities? • Establish a disciplined process. It’s the process that matters, the results are less important • A good process lays the foundation for a good risk management culture • Establish a process that will produce the most reliable results. The results are more important • If it is clear to end users that the results are fictitious then the entire risk management program will be discredited; the operational risk program will be seen to be adding little value • Demonstrate practical value and the program will be a success and subsequently create the right culture Copyright © 2004, OpRisk Advisory LLC. All rights reserved. Consider introducing a disciplined process that produces accurate results which facilitate educated decisions making. RISKS What type of risks do I face? CONTROLS Which are the largest risks? How well are these risks being managed? Manage Controls through Cost Benefit Analysis Copyright © 2004, OpRisk Advisory LLC. All rights reserved. To ensure the goal is practical, one needs to express it in the context of a business problem • Consider two risks: Unauthorized Trading and Money Transfer • Past Audits reveal that both risks are under-controlled • To address Unauthorized Trading risk one must improve segregation of duties and audit frequency. (Solution: hire four new staff; cost = $600,000 per year) • To address Money Transfer risk one must improve the system (Solutions: buy new system; cost = $5 million) • You have $4 million in your budget. Where do you invest your money? Copyright © 2004, OpRisk Advisory LLC. All rights reserved. Effectively managing operational risk requires a foundation designed to turn raw operational risk data into information that supports managerial decision making MANAGEMENT • Awareness of real exposures Economic Profit INFORMATION DATA • Loss data collection FOUNDATION • Risk indicator data collection • Risk strategy, tolerance • Control selfassessment • Roles and responsibilities • Risk assessment and analysis • Policies and procedures • Automatic notification • Risk definition and categorization • Expected Loss – how much do I lose on average • Unexpected Loss – how much I could reasonably expect to lose in a bad year • Control Scores – how good are the controls I have in place • Follow up action reports Management & Control Quality Copyright © 2004, OpRisk Advisory LLC. All rights reserved. • Knowledge of controls quality • Cost benefit analysis • Improved risk mitigation and transfer strategy DEFINITION AND CATEGORIZATION What does operational risk include?

All rights reserved. ALTERNATE APPROACHES TO RISK ASSESSMENT Even with significant amounts of historical loss data it is virtually impossible to reliably estimate severity parameters. Number of Events Size of Loss Copyright © 2004, OpRisk Advisory LLC. All rights reserved. It is also very difficult to reliably estimate severity probabilities at different quantiles. Multiple estimates often create internal inconsistency 1 in 1 years P = $1,000 1 in 10 years = $10,000 1 in 20 years = $25,000 1 in 100 years = $50,000 0-10 1020 2030 3040 4050 Impact Copyright © 2004, OpRisk Advisory LLC. All rights reserved. Disciplined scenario analysis has been found to be moderately reliable and has produced valuable business benefits. • The analysis is based on factual, historical (external) loss data • Risk magnitude is clearly defined as potential loss at a specified confidence level, such as 99% • A 99% level event is defined to mean the second highest loss in one hundred years • This is further clarified – put into practical terms – based on loss experiences of ten peer banks; (similar size, similar controls), the second highest loss in the last ten years for the peer group The whole purpose of this analysis is to allow the bank to compare the magnitude of loss at the same probability level: 50 foot tidal wave vs. 100 tidal wave $10 million money transfer loss vs. $100 million sales practices loss Copyright © 2004, OpRisk Advisory LLC.

SUMMARY & CONCLUSIONS Integrated risk measurement and management can produces value, where the results are meaningful • Risk assessment is feasible and practical, but must be implemented only after one fully understand the meaning of the word risk and the technical challenges. • Control assessment is feasible and practical, but must only be implemented after one understands the how to make a subjective process more objective. • Integrated risk and control assessment or measurement promotes educated decision making, which in turn facilitates prudent risk management an can contribute to the creation of a good risk culture. Copyright © 2004, OpRisk Advisory LLC. All rights reserved. COSO was conceived in the early 1990’s – the first attempt at standardizing what was a subjective and inconsistently applied method for identifying, assessing, controlling and managing operational risks • However, in the context of modern operational risk management, we have learned: • The definition of risk magnitude under COSO is inconsistent with that used in the risk management industry, including the BIS • The approach is highly subjective, resource intensive and generates a huge catalog of unmanageable ‘risks’ • COSO approach to risk assessment (likelihood - impact analysis) focuses attention on what are likely to be phantom risks, not real risks. It produces both false positives and false negatives. • Any prioritization of controls based on this spurious and misleading information may lead to enhancing controls in areas that are already over-controlled, while ignoring areas of control weakness Copyright © 2004, OpRisk Advisory LLC.

He has eight years experience in operational risk measurement and management and approximately twenty years of professional experience. His areas of expertise include: establishing an integrated operational risk measurement and management framework, developing policies and procedures, internal loss event database design and implementation; data quality assessment, data sufficiency, risk indicator identification, risk and control self assessment, disciplined scenario analysis, causal/predictive modeling, advanced VaR measurement techniques and economic capital allocation. . Mr. Samad-Khan has advised many of the world’s leading banks on operational risk measurement and management issues. His significant practical experience in this field comes from managing the implementation of ten major operational risk consulting engagements at leading institutions in North America, Europe and Australia. Key elements of the ORA framework and methodology have been adopted by dozens of leading financial institutions worldwide and have also been incorporated into the BIS guidelines.
