  • 1. Credit Loss Estimation - Industry Challenges and Solutions for Stress Testing May 21, 2014
  • 2. Objectives 1. Review basic background around DFAST requirements and stress testing 2. Introduce a methodology and platform to derive PDs and LGDs for firms that need to develop internal PD and LGD estimates. 3. Introduce a separate methodology for deriving conditional loss estimates at a granular, bottom-up level for firm’s that have a PD and LGD for their underlying obligors 4. Questions and Answers 2
  • 3. Background 1
  • 4. Stress-Testing and Capital Planning Financial and Risk Forecast » Pro-forma balance sheet (under scenarios) » PPNR » Losses, charge-offs, and recoveries » Valuations » Operational risk(s) » Accounting measures (e.g., DTA, Goodwill) » Documentation and Validation Commercial Lending Retail Lending Discretionary Portfolio Finance and Accounting Treasury Funding Credit Risk Trading Capital Planning Industry Observations: » The stress-testing process requires an unprecedented amount of coordination and collaboration across numerous front, middle, and back office functions. » Communication, documentation, and well defined business processes are required, and assumptions made to conditional forecasts require justification. » Governance of the process can be as important as the result(s). The FRB is more highly focused on process than ever before in determining compliance. » Risk quantification is critical at all levels, with challenger approaches considered sound practice. » Best practice requires firms leveraging industry know- how, and development of solutions that are tailored to the specific needs, business model(s), financial risks, and end-user needs, not merely back-office functions. » Creating increased efficiency in the process is necessary, motivating cost savings, and improving operational and data-driven resilience. 4
  • 5. Problem Definition CCAR Banks » To date, many firms have been “fighting the CCAR fire” (CCAR Fatigue). Little time to automate and enhance the process. » After 3 CCAR submissions, large banks are thinking about: — Better use and management of models — Long term vision — Incremental step plan » Themes — Automation of calculation and reporting, to “wrap around” highly complex stress testing & capital planning processes and workflows — Robust, built-for-purpose infrastructure that is flexible enough to adapt to internally AND externally developed analytics and data — Control over assumption inputs and result output — Retooling of data acquisition from LOBs — Statistical modeling of PPNR components — Challenger model approaches DFAST Banks » Much lower compliance threshold than CCAR banks » Difficulties exist in meeting stress testing guidance due to historical reliance on expert judgment in credit processes (e.g. judgment driven risk ratings, lack of bifurcation) » Limited investment in data collection and storage for credit elements needed for loss and PPNR estimation » We observe differences in approach due to: — Size and complexity of the bank — Growth aspiration » Themes — Loss estimation improvements — Report assembly — Rating system redesign — Spreading systems and tools — Data management 5
  • 6. DFAST Requirements March 13, 2014 Final Rule: 1. Timelines 2. Data Sources and Segmentation 3. Model Risk Management 4. Loss Estimation 5. Pre-Provision Net Revenue (PPNR) 6. Balance Sheet and Risk-Weighted Asset Projections 7. Allowance for Loan and Lease Losses (ALLL) 8. Controls, Oversight and Documentation 9. Reporting and Disclosure 6
  • 7. The Most Common Concern is Credit Losses Under Stress Economic Conditions » Real GDP Growth » Employment » Interest Rates » Home Prices » (Others) Capital and Liquidity Metrics » Portfolio loss levels » Impact to earnings » Impact to cash » Implied risk-based capital ratios Credit Quality Metrics » Quarterly expected loss rates by portfolio segment Econometric Models Balance Sheet & Income Statement Models Economic Forecast Assumptions 7
  • 8. Loss Modeling » Top-down modeling approaches (portfolio level) – Global transition matrices – Portfolio level – Asset-class/Call Report category » Depending on size and complexity, bottom-up models – Capture obligor/borrower level details – More consistent with business-line approaches » Challenges: – Reliable PD and LGD – Data availability 8
  • 9. Multiple Approaches to Credit and PPNR Stress Testing are a Must Principle 2: An effective stress testing framework employs multiple conceptually sound stress testing activities and approaches “All measures of risk, including stress tests, have an element of uncertainty due to assumptions, limitations, and other factors associated with using past performance measures and forward- looking estimates. Banking organizations should, therefore, use multiple stress testing activities and approaches …, and ensure that each is conceptually sound. Stress tests usually vary in design and complexity, including the number of factors employed and the degree of stress applied. A banking organization should ensure that the complexity of any given test does not undermine its integrity, usefulness, or clarity. In some cases, relatively simple tests can be very useful and informative. Furthermore, almost all stress tests, including well-developed quantitative tests supported by high- quality data, employ a certain amount of expert or business judgment, and the role and impact of such judgment should be clearly documented”. Interagency Guidance on Stress Testing for Banking Organizations with Total Consolidated Assets of More Than $10Bn SR Letter 12-7, May 14, 2012 9
  • 10. Modeling Challenges: Credit Risk » Major themes regarding quantitative modeling for CCAR purposes: – Asset-class coverage – Variable selection – Primary and challenger model approaches – Segmentation and granularity / White-box v. Black-box – Data and Data Availability – Gathering all of the required modeling data in one place – Loss-emergence – Back-testing and benchmarking 10

  • 29. GCorrTM Macro is Extension of GCorrTM Factor Model » GCorrTM does not explicitly account for changes in macro-economic conditions – They are composite metrics that include GDP, unemployment, etc. » GCorrTM Macro measures the correlation between each MV and our underlying GCorrTM credit factors » GcorrTM Macro is able to compute borrower-level sensitivities to changes in macrovariables – The model quantifies impact of changes to MVs to changes in borrower credit quality (PDs, LGDs) 29
