1. Peru Basel II implementation Setiembre 2009 APEC

2. Experience in Basel II implementation The SBS has reinforced a regulatory framework to enable firms making an appropriate identification, evaluation, treatment and control of risks. Basel II implementation process is progressing quite well in Peru: Changes in the General Law allow the application of capital requirements to credit, market and operational risk according to Basel II. A regulatory framework for the implementation of Basel II has been made available to the public (publications and pre announcing of new rules) 2

3. Main changes in Banking Law DL 1028 Minimum capital requirements for credit, market and operational risks (Pillar I of Basel II) Increase of the minimum capital ratio and maintenance of suitable additional buffer, according to entities’ risk profile and the business cycle (Pillar II of Basel II) Definition of capital structure and proposal of limits on its composition (Basel) Information transparency (Pillar 3 of Basel II) Transparency: Obligation to pre announce new rules regarding capital requirement and loan loss reserves.

4. Implementation Schedule April 2009 Opening application to Operational risk (OR) - ASA July 2009 Capital requirement: CR: no change MR: Standardized approach OR: Basic approach Opening application to advance models: VaR, IRB, AMA July 2010 Capital requirement: CR: standardized approach

10. Sovereign exposures Weight factors of Sovereign exposures of foreign countries are found in the Accord according to international risk rating agencies. Sovereign exposures referred only to Central Banks and Central Government exposures. The rest of public institutions will be treated as corporates. Peruvian local currency sovereign exposures, as well as local and foreign currency reserves and other Peruvian Central Bank operations have a weight factor of 0%. Peruvian foreign currency sovereign exposures (except reserves), will have a weight factor according to the following formula:

11. 11 Credit conversion factors (CCF) Basel I Basel II Peru CR Regulation Confirmations of self-liquidating irrevocable trade letters of credit up to one year, when the issuing bank is a high rating foreign financial system institution according to the CB.

12. The regulation considers fundamental IRB (FIRB) and advanced IRB (AIRB) Parameters are required to be calculated taking into account a complete business cycle (independently of the minimum period of observations) Internal Models (IRB)

13. Definition of Default Past due loan for more than 90 days Retail debtors: by operation Non retail debtors: by debtor Debt instruments are considered in default since the first day of delay after the settlement period. Change to a restructuring situation In the last 5 years, the debtor or the operation has registered more than one change in contract conditions (unless the firm can make a better estimation of its change to a default situation) The firm considers that the debtor is unable to partially or totally fulfill its obligations according to the agreement.

14. Leaving default From the moment of non default, punctually fulfillment of liabilities for 12 consecutive months. During this period, the debtor will be able to register a maximum delay of 7 consecutive days and a maximum accumulated delay of 25 days (unless the firm can make a better estimation of the change to a non default situation) The firm considers that the debtor is able to fulfill all its obligations. This condition will be valid only when the reason of non fulfillment is due to qualitative criteria.

15. Peru Basel II implementation: Pillar I: Market risk

16. Current Methodology Firms will be able to calculate capital requirement for market risks through one of the following ways: 1.Standardized Method 2.Internal Models 3.Combination of standardized method and internal models. It must be considered that each type of risk should be evaluated using only one method. Changes in regulation Inclusion of interest rate risk measurement in trading book and commodities risk measurement, as part of the standardized method. Use of internal models with previous authorization of the SBS.

17. Trading book for market risk capital requirement SBS will consider the following instruments as part of trading book: a) Instruments registered in trading book b) The following instruments registered in available-for sale category: Debt CDBCRP Sovereign bonds (VAC-bonds not included) Global bonds Brady bonds Equity: IGBVL shares Mutual funds (at least 70% of the fund in shares) a)Speculative derivatives b)Derivatives that hedge a and b investments c)Commodities

18. Peru Basel II implementation: Pillar I: Operational risk

19. Capital requirement for operational risk Firms must use one of the following methods. a. Basic indicator approach – BIA (function of net income) b.Alternative Standardized approach - ASA (function of net income by business lines, except retail and commercial banking lines) c.Advanced measurement approaches – AMA (probabilistic calculations) The use of ASA or AMA requires express authorization of the SBS Basel II established methodologies are followed.

20. Operational Risk Gradual implementation of operational risk requirement: SBS would expect that during the implementation, entities are able to meet the requirements to apply to ASA, and thus avoid the application of 100% according to BIA. Jul 2009Jul 2010Jul 2011 40%50%100%

21. Peru: Implementation of pro-cyclical loan loss reserves

22. Regulatory reform of the SBS Foreign exchange credit risk regulation January 2005 Resolution N° 0041-2005 Regulation for foreign exchange credit risk management Sets minimum prudential standards with respect to granting redits in foreign currency, as an additional component for defining the ability to pay. To that effect, minimum requirements in managing this risk are defined. In case of not satisfying those requirements, additional provisions are set. May 2005CIRCULARNº B-2145-2005 F- 0485-2005 CM-0332-2005 CR-0201-2005 EAF-0229-2005 EDPYME-0117-2005 Over- borrowing regulation September 2006 S.B.S. Resolution Nº 1237 -2006 Regulation for retail debtors debt overhang risk management. Stipulates that firms must establish policies regarding granting, amendment and revision of revolving credit lines, including explicit standards and measures to include over-borrowing of retail debtors in credit evaluation. Additionally, sets minimum requirements for management of retail debtors over-borrowing. Additional provisions will be established on the unused portion of retail revolving credit lines if requirements are not fulfilled. August 2008 S.B.S. Resolution Nº 6941 -2008 New Regulation for retail debtors debt overhang risk management

23. How does Accumulation Rule work? The variable component of procyclical loan loss reserves will be activated in the following situation: The average GDP growth rate YoY of the last 30 months passes from less than 5% to 5% or more. When the average GDP growth rate YoY of the last 30 months is over 5%, and the average GDP growth rate YoY of the last 12 months is higher by 200 basic points to this same indicator calculated a year earlier. When the average GDP growth rate YoY of the last 30 months is over 5%, and 18 months had elapsed since the procyclical rule was deactivated

24. How does Decumulation Rule work? The accumulation rule will be deactivated in the following situations: The average GDP growth rate YoY of the last 30 months passes from a level equal or greater than 5% to one less than this threshold. The average GDP growth rate YoY of the last 12 months is lower by 400 basic points to this same indicator calculated a year earlier.

28. The Banking System has S/. 916 millions of loan loss reserve buffer and S/. 4 134 millions of capital buffer

29. Peru Basel II implementation: Pillar II

30. Additional capital buffer In Peru, the additional buffer is a function of the type of institution (10.5% for commercial banks, 14% for microfinance institutions). This indicator is not very sensitive to risk. Regulatory capital should consist of: 1.Minimum capital : Pillar I 2.Additional capital: Should be determined based on the institution's risk and business cycle. 3.Additional capital according to ICAAP Business cycle indicator Decumulates Accumulates
