ANNEX I
Sensitivity Analyses

1. Stress Test Assumptions
   The table below presents the assumptions and parameters to be applied in the Sensitivity Analyses to be reported to the Banco Nacional de Angola, whose shocks are based on a 12-month horizon.

Risk	Assumptions	Description	Impact
Credit Risk	Increase in credit default by the private sector (Companies and Retail)	Deterioration of impairment stage: 10% of Stage 1 amounts transition to Stage 2 and 15% of Stage 2 amounts transition to Stage 3	Original Position, Accumulated Impairment, Net Income, Ratio of Non-Performing Exposures to Total Credit, Ratio of Regulatory Capital
	Decrease in recovery rate associated with public sector exposures, due to the State's inability to fully repay its debt	Increase in LGD by 10 p.p.
Market Risk	Devaluation of the government securities portfolio	Devaluation of government securities by 15%	Net Income, RWAs, Ratio of Regulatory Capital
	Devaluation of other assets in the trading portfolio (e.g., shares)	Devaluation of trading portfolio assets by 40%
	Exchange rate fluctuation	Depreciation/appreciation of the exchange rate by 25%
Operational Risk	Realization of extraordinary losses associated with operational risk, namely internal and external frauds, penalties for compliance infringements related to anti-money laundering procedures and financial conduct.	Extraordinary loss corresponding to 1% of total Regulatory Capital.	Net Income, Regulatory Capital, Ratio of Regulatory Capital
Liquidity Risk	Reduction in deposits and credit defaults	Reduction in deposits and credit defaults in accordance with Section 2.3 of this Annex	Survival Period, Liquidity Flow Mismatch

2. Additional Information for Calculating Impacts Underlying Liquidity Risk

2.1. Survival Period
The survival period is evaluated using the Institution's stock of liquid assets and corresponds to the number of days during which it ensures the liquidity flows (added to its high-quality liquid asset stock) necessary to meet its payment obligations. This measurement is performed over a maximum time horizon of 180 days. Thus, for each of the 180 days, the following must be calculated:

Liquidity Position (t) = Liquid Asset Stock (t=0) - Cumulative Net Liquidity Flows (t) + Liquidity Reserve (t)

where Liquid Asset Stock (t=0) corresponds to the stock of liquid assets held by the Institution as of the reference date, after applying the weights established in Instruction No. 14/21 of September 27 on Liquidity Risk. The reserve value as of the reference date is kept constant in determining the net position of each day t.

The survival period will then correspond to the number of days elapsed between the reference date and the day prior to the day when cumulative net liquidity flows plus the liquidity reserve become negative, i.e.:

Liquidity Position (t=0) = Liquid Asset Stock (t=0) + Liquidity Reserve (t=0) ... Liquidity Position (t=n-1) = Liquid Asset Stock (t=0) + Cumulative Net Liquidity Flows (t=n-1) + Liquidity Reserve (t=n-1) > 0 Liquidity Position (t=n) = Liquid Asset Stock (t=0) + Cumulative Net Liquidity Flows (t=n) + Liquidity Reserve (t=n) < 0 Number of days of survival = n-1

2.2. Liquidity Flow Mismatch
The mismatch of liquidity flows across different maturity buckets aims primarily to anticipate any significant discrepancies between the maturity of obligations and the maturity of the Institution's assets. The objective is to compare, for each time interval, the difference between inflow and outflow.

Similar to the survival period, the liquidity flow mismatch across different maturity buckets is calculated over a maximum horizon of 180 days. For the calculation, projections of inflow and outflow across different horizons and time scenarios are used.

2.3. Description of Assumptions

Base Scenario
For the purpose of calculating the survival period and liquidity flow mismatches, in the base scenario, Institutions must determine inflows and outflows according to the realization of their internal forecasts. Institutions must describe the assumptions applied in point 7 of Annex II.

Stress Scenario
In addition to the assumptions applied in the base scenario, within the scope of the stress scenario, Institutions must consider the following assumptions:

17.2 Non-financial institutions: Default of 1% in 1st month, 2.5% up to 3rd month, 7.5% up to 6th month (assuming no repayment)
17.3 Individuals: Default of 0.5% in 1st month, 1.5% up to 3rd month, 5% up to 6th month (assuming no repayment)

• The daily reduction corresponds to the initial spot value multiplied by the daily reduction rate, resulting in a constant value. It shall be applied over a period of 180 days or until the total initial value is consumed.
  The default rate must be applied to the total credit amount at the initial moment (reference date of the report).
