Fair Value of Financial Assets and Liabilities FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The measurement of fair value assumes the sale transaction of an asset or the transference of the liability happens within the main asset or liability market, or the most advantageous market for the asset or liability.
For financial instruments with no available market prices, fair values have been estimated by using recent transactions in analogous instruments, and in the absence thereof, the present values or other valuation techniques based on mathematical valuation models sufficiently accepted by the international financial community. In the use of these models, consideration is given to the specific particularities of the asset or liability to be valued, and especially to the different kinds of risks associated with the asset or liability.
These techniques are significantly influenced by the assumptions used, including the discount rate, the estimates of future cash flows and prepayment expectations. Hence, the fair value estimated for an asset or liability may not coincide exactly with the price at which that asset or liability could be delivered or settled on the date of its valuation and may not be justified in comparison with independent markets.
Except as detailed in the following table, management considers that the carrying amounts of financial assets and financial liabilities recognised in the consolidated financial statements approximate their fair values.

NOTE 36 - FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES. continued
The fair value approximates the carrying amount of the following line items due to their short-term nature: cash and deposits-banks, cash items in process of collection and investments under resale or repurchase agreements.
In addition, the fair value estimates presented above do not attempt to estimate the value of the Bank’s profits generated by its business activity, nor its future activities, and accordingly, they do not represent the Bank’s value as a going concern. Below is a detail of the methods used to estimate the financial instruments’ fair value.
a.Financial assets held for trading and Debt instruments at FVOCI
The estimated fair value of these financial instruments was established using market values or estimates from an available dealer, or quoted market prices of similar financial instruments. Investments are evaluated at recorded value since they are considered as having a fair value not significantly different from their recorded value. To estimate the fair value of debt investments or representative values in these lines of businesses, we take into consideration additional variables and elements, as long as they apply, including the estimate of prepayment rates and credit risk of issuers.
b.Loans and accounts receivable at amortised cost and Interbank
Fair value of commercial, mortgage and consumer loans and credit cards are measured through a discounted cash flow (DCF) analysis. We use current market interest rates considering product, term, amount and similar loan quality. Fair value of loans with 90 days or more of delinquency are measured by means of the market value of the associated guarantee, minus the rate and term of expected payment. For variable rate loans whose interest rates change frequently (monthly or quarterly) and that are not subjected to any significant credit risk change, the estimated fair value is based on their book value.
c.Deposits
Disclosed fair value of deposits that do not bear interest and saving accounts is the amount payable at the reporting date and, therefore, equals the recorded amount. Fair value of time deposits is calculated through a discounted cash flow calculation that applies current interest rates from a monthly calendar of scheduled maturities in the market.
d.Short and long term issued debt instruments
The fair value of these financial instruments is calculated by using a discounted cash flow analysis based on the current incremental lending rates for similar types of loans having similar maturities.
e.Financial derivative contracts for trading and hedge accounting
The estimated fair value of financial derivative contracts is calculated using the prices quoted on the market for financial instruments having similar characteristics.
The fair value of interest rate swaps represents the estimated amount that the Bank determines as exit price in accordance with IFRS 13. If there are no quoted prices from the market (either direct or indirect) for any derivative instrument, the respective fair value estimates have been calculated by using models and valuation techniques such as Black-Scholes, Hull, and Monte Carlo simulations, taking into consideration the relevant inputs/outputs such as volatility of options, observable correlations between underlying assets, counterparty credit risk, implicit price volatility, the velocity with which the volatility reverts to its average value, and the straight-line relationship (correlation) between the value of a market variable and its volatility, among others.
Measurement of fair value and hierarchy
IFRS 13 - Fair Value Measurement, provides a hierarchy of reasonable values which separates the inputs and/or valuation technique assumptions used to measure the fair value of financial instruments. The hierarchy reflects the significance of the inputs used in making the measurement. The three levels of the hierarchy of fair values are the following:
•Level 1: the inputs are quoted prices (unadjusted) on active markets for identical assets and liabilities that the Bank can access on the measurement date
•Level 2: inputs other than the quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly
•Level 3: inputs are unobservable inputs for the asset or liability i.e. they are not based on observable market data
NOTE 36 - FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES
The hierarchy level within which the fair value measurement is categorized in its entirety is determined based on the lowest level of input that is significant to the fair value measurement in its entirety.
The best evidence of a financial instrument’s fair value at the initial time is the transaction price.
In cases where quoted market prices cannot be observed, Management makes its best estimate of the price that the market would set using its own internal models which in most cases use data based on observable market parameters as a significant input (Level 2) and, in very specific cases, significant inputs not observable in market data (Level 3), various techniques are employed to make these estimates, including the extrapolation of observable market data.
Financial instruments at fair value and determined by quotations published in active markets (Level 1) include:
-Chilean Government and Department of Treasury bonds
-Foreign instruments
-Mutual funds
Instruments which cannot be observable in the market are valued according to other inputs observable in the market (Level 2).
The following financial instruments are classified under Level 2:
Type of
 financial instrument		Model
 used in valuation		Description of unobservable inputs
● Mortgage and private bonds Present Value of Cash Flows ModelInternal Rates of Return (“IRRs”) are provided by RiskAmerica, according to the following criterion: If, at the valuation day, there are one or more valid transactions at the Santiago Stock Exchange for a given nemotechnic, the reported rate is the weighted average amount of the observed rates. In the case there are no valid transactions for a given mnemonic on the valuation day, the reported rate is the IRR base from a reference structure, plus a spread model based on historical spread for the same item or similar ones.
● Time depositsPresent Value of Cash Flows ModelIRRs are provided by RiskAmerica, according to the following criterion: If, at the valuation day, there are one or more valid transactions at the Santiago Stock Exchange for a given mnemonic, the reported rate is the weighted average amount of the observed rates. In the case there are no valid transactions for a given mnemonic on the valuation day, the reported rate is the IRR base from a reference structure, plus a spread model based on issuer curves.
● Constant Maturity Swaps (CMS), FX and Inflation Forward (Fwd) , Cross Currency Swaps (CCS), Interest Rate Swap (IRS)Present Value of Cash Flows ModelIRRs are provided by ICAP, GFI, Tradition, and Bloomberg according to this criterion: With published market prices, a valuation curve is created by the bootstrapping method and is then used to value different derivative instruments.
● FX OptionsBlack-ScholesFormula adjusted by the volatility simile (implicit volatility), Prices (volatility) are provided by BGC Partners, according to this criterion: With published market prices, a volatility parameter is created by interpolation and then these volatilities are used to value options.
● Guarantee deposits, guarantee received (Threshold)Present Value of Cash Flows ModelCollateral associated to derivatives financial contracts: Average trading swap (CMS), FX and inflation Forward, Cross Currency Swap (CCS), Interest Rate Swap (IRS) y FX options.
In limited occasions significant inputs not observable in market data are used (Level 3). Several techniques are used to perform these estimates, including extrapolation of observable market data or a mix of observable data.

● Loans and account receivable at FVOCIPresent Value of Cash Flows ModelMeasured by discounting estimated cash flow using the interest rate of new contracts.
● Mortgage finance bondsPresent Value of Cash Flows ModelThe yields (YTM) are provided by RiskAmérica according to the following criteria: If, on the valuation date, there are one or more valid transactions on the Santiago Stock Exchange for a given ticker symbol, the reported rate is the weighted average of the observed rates. If there are no valid transactions for a given ticker symbol on the valuation date, the reported rate is a "base YTM," derived from a reference structure, plus a "Model Spread" based on historical spread data for the same or similar securities.
The Bank does not believe that any change in unobservable inputs with respect to level 3 instruments would result in a significantly different fair value measurement.

The fair values of other assets and other liabilities approximate their carrying values.
The methods and assumptions to estimate the fair value are defined below:
-Loans and amounts due from credit institutions and from customers – Fair value are estimated for groups of loans with similar characteristics. The fair value was measured by discounting estimated cash flow using the interest rate of new contracts. That is, the future cash flow of the current loan portfolio is estimated using the contractual rates, and then the new loans spread over the risk-free interest rate are incorporated to the risk-free yield curve in order to calculate the loan portfolio fair value. In terms of behavior assumptions, it is important to underline that a prepayment rate is applied to the loan portfolio, thus a more realistic future cash flow is achieved.
-Deposits and interbank borrowings – The fair value of deposits was calculated by discounting the difference between the cash flows on a contractual basis and current market rates for instruments with similar maturities. For variable-rate deposits, the carrying amount was considered to approximate fair value.
-Issued debt instruments and other financial liabilities – The fair value of long-term loans was estimated by cash flow discounted at the interest rate offered on the market with similar terms and maturities.
The valuation techniques used to estimate each level are defined in Note 1,i). There were no transfers between levels 1 and 2 for the year ended December 31, 2025 and 2024.
The table below shows the effect, at December 31, 2025 and 2024, on the fair value of the main financial instruments classified as Level 3 of a reasonable change in the assumptions used in the valuation. This effect was determined by a sensitivity analysis under a 1bp scenario, detailed in the following table:
