Annual Report 2013 PT Bank Mandiri Persero Tbk. risk management To integrate risk management on a bankwide basis, Bank Mandiri has adopted the ERM system so as to facilitate the holistic monitoring of risk management, including calculating the capital needed to cover all types of risk. The ERM system has the capacity to calculate capital charges using the Standardized Approach and Advanced Approach, and to apply operational risk management tools, active portfolio management, stress testing and value-based management.

4. METHODOLOGY MODEL ANALYTICS

Bank Mandiri consistently conducts risk assessment based on international best practices using both the quantitative and qualitative modeling approaches through the development of risk models such as rating, scoring, value at risk VaR, portfolio management, stress testing and other models so as to support judgmental decision making. The Bank’s risk models are regularly recalibrated and validated by the independent Risk Model Validator Unit, whose function is to maintain the reliability and validity of models and ensure that they satisfy the regulatory requirements RISK MANAGEMENT THROUGH FINANCING Risk management through inancing in Bank Mandiri includes the diversiication of inancing sources through policies that are harmonized with our long-term strategic plans, and eicient capital allocation policies in business segments that have optimal risk-return proiles including placements in subsidiaries. This is intended to meet the expectations of our stakeholders, including investors and regulators. Bank Mandiri consistently ensures that it has suicient capital to cover all credit risks, market risks and operational risks based both on regulatory requirements regulatory capital and internal needs economic capital. Bank Mandiri adheres to the Bank Indonesia regulations on Basel II in the calculation of its capital adequacy for credit risks, market risks and operational risks. In the case of credit risks, Bank Mandiri uses the Basel II standardized approach 1 and has commenced simulations of the Internal Ratings-Based Approach. While the Basel II Standardized Approach to credit risks does not require the use of external ratings data from a bank’s borrowers, Bank Mandiri has nevertheless initiated simulations involving the use of such external ratings data. In the market risk ield, Bank Mandiri uses the Standard Model 2, while internally it uses the Value at Risk model. For operational risks, Bank Mandiri applies the Basel II Basic Indicator Approach 4 and has also conducted simulations of the Standardized Approach. As per end December 2013, AMTR and capital adequacy were as shown in the following table: 5 1.

The credit risk capital load using the Standardized Approach based on risk weighting as per end December 2013 is as shown below: Asset Composition by Credit Risk Weighting Standardized Approach – December 2013 Bobot Risiko 0 Bobot Risiko 20 Bobot Risiko 35 Bobot Risiko 40 Bobot Risiko 50 Bobot Risiko 75 Bobot Risiko 100 Bobot Risiko 150 0,33 0,65 13,14 12,92 44,25 0,20 24,90 3,60 The Bank also has to conduct lending capital load simulations using Advanced IRBA Internal Rating Based Approach, which calculates the capital adequacy ratio more eiciently. Currently, Bank Mandiri is also developing economic capital needs models for credit risk and operational risk assessment, while at the same time providing a basis for the Bank to commence the application of VBM Value Based Management through the measurement of RORAC Return On Risk Adjusted Capital. As a irst step in the implementation of VBM, Bank Mandiri has begun to use RORWA Return On Risk Weighted Asset indicators that are more intuitive for business units as part of the preparations for the full implementation of RORAC. Bank Mandiri has been preparing for the implementation of Basel III based on the Basel documentation and the regulations and initiatives issued by Bank Indonesia 6. The Bank actively participates in Basel III working groups and the Quantitative Impact Studies QIS conducted by Bank Indonesia. Based on the position per June 2013, the QIS results showed that in general Bank Mandiri is in compliance with the Basel III guidelines, with a higher Capital Adequacy Ratio resulting from the simulations than is required under Basel II. This is because Bank Mandiri’s capital structure is dominated by Tier 1 Common Equity. The QIS results also showed that Bank Mandiri operates at a low risk level, as shown by a satisfactory leverage ratio and a high liquidity ratio, which results from the tight control exercised by the Bank over of balance sheet exposure. In addition, Bank Mandiri’s liquid asset position and balance sheet composition were consistent with the Basel III requirements. RISK MANAGEMENT THROUGH OPERATIONS Risk management through operations intended to maintain credit risks, market risks and operating risks at an acceptable level. Bank Mandiri manages risk appetite and risk tolerance by applying policy limits and system limits, which are prepared and proposed by the business units, in collaboration with the risk management unit, for approval by the Risk Management Committee. The determination of limits is based on overall limits, limits per risk type and speciic limits per functional activity that entails risk exposure. These limit policies not only function in the risk management process, but also encourage business strategies and business expansion plans to adhere to optimal risk-reward proiles. risk management Annual Report 2013 PT Bank Mandiri Persero Tbk. Credit risk management is performed at the front end, middle end and back end, while market and liquidity risk management is conducted through system limits. Operational risk management in respect of the Bank’s products and activities is conducted by each line unit, and is reviewed bankwide by the risk management unit, with the efectiveness of assurance being assessed by the Internal Audit unit.
