Article 8. (Adjustments to the Shock)

1.

ANNEX II Notes for Filling Out the Interest Rate Risk in the Banking Book Information Provision Map

1. Balance sheet positions and off-balance sheet items included in the banking book and exposed to interest rate risk must be assigned to their respective time band, considering, for fixed-rate instruments, their respective residual maturity periods, and for variable-rate instruments, the period remaining until the next interest rate repricing.
2. The amounts of assets and liabilities must be valued at their fair value, net of specific provisions, whenever applicable.
3. Positions in financial derivatives subject to interest rate risk must be treated as described in Annex I of the Guide on calculation and requirement of regulatory capital for market risk and counterparty credit risk in the trading book.
4. The exchange rate to be used for instruments contracted in foreign currency is the reference exchange rate of the Bank of Angola on the date of information provision.
5. Whenever elements denominated in a foreign currency and exposed to interest rate risk represent more than 5% (five percent) of the banking book, a specific analysis and provision of information for that currency must be carried out.
6. Attached to the forms, the following information must be explicitly stated, with the appropriate level of detail: a) how elements were considered whose effective maturity or repricing periods diverge from contractual terms;

CONTINUATION OF NOTICE NO. 08/2016 Page 10 of 11

b) calculations performed and eventual hypotheses considered regarding variations in items that indicate an impact due to changes in interest rates, but which are not directly dependent on the interest rate, notably the effects on profits recorded as commissions; and c) hypotheses admitted regarding the sensitivity of non-remunerated deposits to variations in interest rates. 7. The elements necessary for the provision of quantitative information to the Bank of Angola, within the scope of interest rate risk in the banking book, are described below: (A) Weighting factor, calculated based on: i) an estimate of the modified duration of the banking book elements with maturity equal to the average term of each time band, assuming that all assets, liabilities, and off-balance sheet items are remunerated at a rate of 5% (five percent) and that the discount rate for the entire maturity spectrum is equally 5% (five percent); and ii) a hypothetical parallel shift of the yield curve of 2% (two percent). (B) Weighted position = position in each time band multiplied by (A). (C) Accumulated impact of a parallel shift of the yield curve of 2% (two percent), corresponding to the sum of positions in each time band multiplied by the weighter. (D) Regulatory capital. (E) Impact of the shock on capital, in percentage, which is obtained by dividing the accumulated impact of a parallel shift of the yield curve of 2% (two percent) (C) by the regulatory capital (D). (F) Weighting factor, calculated based on: i) the average residual term of each maturity band, and;

CONTINUATION OF NOTICE NO. 08/2016 Page 11 of 11

ii) a hypothetical parallel shift of the yield curve of 2% (two percent). (G) Weighted position = position in each time band multiplied by the weighting factor (F). (H) Accumulated impact of a parallel shift of the yield curve of 2% (two percent), calculated by the sum of positions in each time band multiplied by the weighter. (I) Net interest margin (interest income – interest costs). (J) Impact of the shock on net interest margin, in percentage, obtained by dividing the accumulated impact of a shift of the yield curve of 2% (two percent) (H) by the net interest margin (I).
