8 4. To B2 or not to B2? – Internal considerations 4.1.1 Resource implications:Significant investment in IT systems would be required.Data availability challenges.Complex model requirements.Ownership, co-ordination of efforts (Finance, IT, Risk).4.1.2 B2 implementation cost and risk:Estimated at 2.8% of annual Operating Expenditure, expensed over 5 years.Capital saving benefits uncertain.High risk of rework, due to regulatory process uncertainty.4.1.3 Change management:Changes to IT systems and business processes, policies and procedures.Challenge to manage required change effectively.
9 4. To B2 or not to B2? – Internal considerations 4.1.4 Other compliance requirements:AC133 (IFRS), AML, etc.4.1.5 Business benefits:Enhanced reputation.Improved control environment, information integrity, etc.Tools to improve operational and process efficiencies.4.1.6 Enhancing risk management framework:Opportunity to further embed risk-reward management culture in decision making.AC133: Accounting standard AC133, “Financial Instruments: Recognition and Measurement”, a recent addition to South African GAAP and local equivalent of IAS39 / FAS133.IFRS: International Financial Reporting StandardsAML: Anti-Money Laundering
10 4. To B2 or not to B2? – External considerations 4.2 EXTERNAL CONSIDERATIONS: EMERGING MARKETS ACCEPTANCE4.2.1 Cross border capital flows:Improved transparency of SA banks’ risk profiles and best practices benchmark compliance could improve ratings.Improved capital inflows could result.4.2.2 Unintended consequences:Higher capital requirements volatility in emerging markets.More challenging for banks to maintain profitability due to combined impact of AC133 and B22.214.171.124 Benefits to banking and financial system:Improved risk management practices could lead to reduced systemic risk and improved market perception.More efficient utilisation of capital employed in the banking system.Growth in risk transfer instruments promoted.Industry consistent disclosure.Improved corporate governance through board and senior management oversight requirements.Complements supervisor’s risk based approach.
11 4. To B2 or not to B2? – Conclusion Reputational risk of non-compliance too high.Large retail base should lead to reduced capital requirements.Positive spin-offs.Benefits outweigh costs.B2 should be viewed as an opportunity to enhance competitive position.B2No B2
12 5. B2 Implementation Strategy Absa’s goal:To be fully B2 compliant by January 2007B2 approach aspirations:Retail credit exposures: IRB AdvancedCorporate credit exposures: IRB foundationOperational Risk: Advanced measurement approachSome subsidiaries will be excluded from Group adopted approach based on materiality and will follow standardised approach.IRB: Internal Ratings Based

17 7. Delivering the B2 solution Models: Credit RiskPD:Corporates: KMVSMEs: Moody’s RiskCalc (SA default database)Retail: Own development based on internal default experience related to application and behavorial scoring (TRIAD)Specialised lending: Slotting criteriaBanks and sovereigns: Derived from internal to external rating mappingsLGD Retail:Own development based on internal recovery experienceEAD Retail:Own development based on internal draw down experienceCapital measurement:Pillar 1: SAP Bank AnalyserPillar 2: Own development in SASPD: Probability of DefaultSMEs: Small and Medium sized EnterprisesLGD: Loss Given DefaultEAD: Exposure At Default
19 7. Delivering the B2 solution Data Collection StrategyRetail credit loss data:Data collection efforts commenced some time ago.Four years of historical data available already.SME credit loss data:Data pooling arrangement with peer group initiated.Corporate, sovereign, banks credit loss data:Insufficient data availability in local market.Statistical model approach to be followed.Calibrated to international default experience.Operational risk:Historical data available for frauds and some loss events.Data collection efforts for remaining loss types have commenced.Data pooling arrangement with peer group under discussion.Centralised financial transaction database:Development in progress.

Absa had its internal model approved for the computation of position risk capital in the trading book in 1998.Capital requirements for equity risk: Equities in the banking book under the internal models approach (VaR).
26 8. B2 / IFRS alignment Overlap between IFRS and B2. Common data requirements.Common valuation models.Provisioning / capital interrelationship.Capital adequacy implications of fair value adjustments.B2 / IFRS development strategy to ensure consistency in risk and financial performance measurement.Common validation needs.Ownership.B2: Basel II Capital AccordIFRS: International Financial Reporting Standards
27 9. Early results Capital impact Ongoing capital impact measurement. As of December 2003:Overall: Estimated 5% capital savingRetail credit portfolios: Significant (30%+) capital savingSMEs: Slight increaseCorporate : IncreaseBanks: Significant increaseOperational risk capital: 7% increase (preliminary AMA)Early indication of further capital relief from EL / UL amendment.AMA: Advanced Measurement ApproachEL / UL: Expected Loss / Unexpected Loss
28 9. Early results Strategic implications Protecting the Retail base. Increased focus on Wealth Management services.Increased focus on CRM.Reviewing LTV lending criteria for some Mortgage segments.Reviewing speculative grade Corporate lending criteria.Increased focus on customer retention.Consider risk-based product re-pricing (declining capital needs over loan life).CRM: Customer Relationship ManagementLTV: Loan-To-Value

30 11. Industry Collaboration Industry has taken initiatives …Credit loss data poolingOperational loss data poolingSME default data (in progress)SME LGD data (next phase)Still under discussionIssues: context, confidentiality, etc.
31 12. Remaining issues and challenges – Pillar 2 clarity Judgmental approach to Pillar 2 – strong reliance on supervisor expertise.Economic capital measurement assumptions for interest rate risk in banking book.Measurement issues and assumptions for risks not covered under Pillar 1 – eg. Liquidity risk.Capital stress testing methodology.Capital buffer requirements.Credit concentration risk measurement approaches.Risk diversification treatment in buffer determination.
32 12. Remaining issues and challenges – Pro-cyclicality B2 Credit Capital Risk Weight CurveStatic LGD, EAD and term assumptions.Non-linear sensitivity to credit quality changes.
33 12. Remaining issues and challenges – Pro-cyclicality Absa’s capital requirement would have increased by over 30% under a B2 regime in the aftermath of the 1998 Emerging Markets Crisis.Problem exacerbated by dynamic internal rating systems.Capital stress testing/planning simulation model capability.Buffer management.Ongoing capital attribution analysis.Hedge capital fluctuations.
34 12. Remaining issues and challenges – Model validation Supervisory approach to model validation.Statistical validation (backtesting, out of sample testing, etc.) not feasible in all areas.Benchmarking.Mapped ratings.Methodology reviews.Pragmatic approach.Ongoing validation strategy.Rating agents.
35 12. Remaining issues and challenges – Capital level & Ratings Long-term Impact of Basel II on Bank RatingsHigher CAR won’t necessarily lead to upgrade, and cutting capital because of a higher CAR could lead to a downgrade.But better data on risk profile will be considered, and better risk management a positive:Better asset allocationBetter risk-adjusted pricing.“”Moody’s Investors ServicesCAR: Capital Adequacy Requirements
36 13. Conclusion B2 benefits outweigh costs. Plethora of model tools and data availability is improving.Strong programme management required for successful implementation.Industry collaboration critical.Communication and education – bank management, investors, stakeholders, etc.Key role of Regulator: To be pro-active on issues - reduce uncertainties.
