and the scaling factor 976.5, which is calibrated so that the IRB benchmark risk weight equals 100% for values of PD and LGD equal to 0.7% and 50% respectively 157 Maturity Adjustments to The Risk Weights, Derived From MTM-models Maturity Adjustments PD(%) Year Years Years Years 0.03 0.4 1.0 1.6 2.3 0.05 0.4 1.0 1.6 2.1 0.10 0.5 1.0 1.5 2.0 0.20 0.6 1.0 1.4 1.8 0.50 0.7 1.0 1.3 1.6 1.00 0.7 1.0 1.3 1.5 1.40 0.8 1.0 1.2 1.5 3.30 0.8 1.0 1.2 1.3 6.60 0.9 1.0 1.1 1.3 15.0 0.9 1.0 1.1 1.2 158 Appendix CIBC Operational Risk Loss Types Legal Liability Employee* Wrongful termination Discrimination Workplace safety Privacy violation Client Restitution * Goodwill payments Payments to make client whole Theft, Fraud, Unauthorized Activities Theft/ Fraud * Defalcation Forged Cheques Worthless deposits Counterfeit cheques Account takeover Robbery Kiting Misappropriations of assets Credit card fraud Client * Fiduciary breaches/guidelines Suitability/ disclosure Account churning Aggressive sales Violation of confidentiality Lender liability Third Party * Copyright/patent /license infringement Supplier lawsuits Unauthorized Activity * lending/trading above limits intentional mismarking of positions unlicensed activity hiding trades/ loans unapproved account access Regulatory, Compliance and Taxation Penalties * Failure to comply with regulations Money laundering Tax non compliance Market manipulation Insider trading Bribes Transaction Processing Risk * Loss or Damage to Assets * Damage to buildings equipment physical certificates physical commodities holdings (eg gold) records * indicates the level at which Op VaR is calculated for each business line Data entry errors Delivery failure Collateral management failure Incomplete legal documents Reporting errors Calculation errors Wrong delivery Wrong payment amount Cash shortages Missing or disputed cheques 159 Appendix CIBC Operational Risk EI, PE, LGE LR = PE x LGE EI (Base) PE LGE Legal Liability: Client No of clients * Av Bal Per client No of lawsuits/no of clients Av loss/Av bal Per client Employee No of employee * Av Comp No of lawsuits/no of employees Av loss/Av Comp No of penalties1/no of accounts Av penalty1/Av balance per acc’t No of damages/no of phy assets Av loss/Av value of phy assets No of restitutions/no of accounts Av restitution/Av bal per account No of accounts * Av bal per account No of frauds/no of accounts Av loss/Av balance per account No of transaction & Av value per trans No of frauds/no of transactions Av loss/Av value per transaction No of errors/No of transaction Av loss/Av value per transaction Regulatory, Compliance and Taxation Penalties: No of physical assets * Av value Loss of, or Damage to Assets: No physical assets * Av value Client Restitution No of accounts * Av bal Per account Theft, Fraud and Unauthorized Activities Or Transaction Processing Risk No of transaction * Av value per transaction includes cost to comply 160 Appendix Eligibility Criteria: for IMA IMA • Active involvement of board and senior management • Independent operational risk management and control process covering design, implementation and review of measurement methodology Effective • Internal Audit Groups conduct regular reviews of management process and measurement methodology Risk Management and Control • Documentation of risk management systems • Bank must use data for risk reporting, management reporting, capital allocation, risk analysis, etc 161 Eligibility Criteria: for IMA IMA • Appropriate risk reporting systems to generate aggregate data used in capital calculation • Construct management reporting based on results • Systematically tract relevant operational risk data Measurement and Validation • Sound internal loss and event reporting practices supported by loss database systems • Regular validation of loss rates, risk indicators and size estimations, supplemented with external data • Regular scenario analysis and stress testing • Supervisors must examine the data collection, measurement, validation process and assess the appropriateness of the operational risk control environment 162 Appendix Operational Risk Disclosure: Pillar 1) The approach a bank qualifies for (i.e IMA) 2) Key elements of operational risk management framework including information about the following: a) risk policies b) organizational structure c) risk reporting system d) documentation of risk management procedures e) effective use of an information system f) organization (reporting framework) and responsibilities of an independent risk control unit g) independent reviews of the risk management systems at least annually h) involvement of board and senior management in taking responsibility for operational risk;
