3.3 Evaluation of capital needs for market risk Similar aspects to those indicated in the first paragraph of point 3.1 will be considered. In the detail regarding models, it is necessary to explicitly state how the main parameters supporting them are determined (e.g., estimated volatility), as well as the value of these parameters. In applicable cases, information will be presented disaggregated for equities, foreign currency, BCRA monetary regulation instruments, fixed-income securities and interest rate derivative instruments. 3.4 Evaluation of capital needs for operational risk Similar aspects to those indicated in the first paragraph of point 3.1 will be considered. 3.5 Evaluation of capital needs for interest rate risk in the investment portfolio (RTICI) Entities will consider their systemic importance at the local level and the group to which they belong, in accordance with the classification provided for in the standards on “Authorities of financial entities”. Taking into account such classification and what is established in the “Guidelines for risk management of financial entities”, the models used to determine capital needs for this risk will be detailed, justifying their practical application in management, their last validation, modeling assumptions and the treatment of key parameters, as well as the criteria applied for constructing the yield curve, determining its variations and how these impact the calculated economic capital. Although regulation provides guidelines for the treatment and allocation of cash flows to time bands under the Standardized Framework, criteria and procedures determined for applying the modeling assumptions contemplated therein will be additionally detailed. When entities apply the Standardized Framework and, at the same time, estimate capital needs through their Internal Measurement Systems (SIM), the greater of both will be considered for subsequent aggregation to capital needs across various risks. The methodology used by the financial entity to calculate its economic capital for interest rate risk using its Internal Measurement Systems (SIM) must be described, and whose amount is reported in the rows labeled “SIM” of the summary table corresponding to subpoint 4.1. of the report model included in point 8. Finally, financial entities that identify themselves as atypical will indicate such condition in this point. B.C.R.A.

This section will also capture future changes in risk and capital management that the entity plans to undertake, such as modifications to general risk policy, improvements in tools for managing and controlling a specific risk, among others. In any case, all aspects related to future improvement plans will be included exclusively in this section, although cross-references may be made in the corresponding section. 7. Other matters Relevant issues that the entity considers necessary or convenient to include in the report, not covered in any of the previous sections, will be captured as applicable. Furthermore, it is necessary to indicate the most significant changes introduced in the capital self-assessment process during the past year, which are captured in this new CSR. If they generate an impact on capital determination for any risk(s), specify such situation. Additionally, aspects observed by the SEFyC that are pending implementation as of the date must be recorded, indicating in each case the estimated completion date for the tasks. B.C.R.A.
