Disclosure of estimations of fair value [abstract] |
ESTIMATION OF FAIR VALUE | NOTE 5 – ESTIMATION OF FAIR VALUE The fair value of the financial assets and liabilities traded in active markets (such as financial assets in debt securities, equity securities and derivatives actively listed in stock exchanges or interbank markets) is based on dirty prices supplied by a price vendor. A dirty price includes accrued unpaid interest on the security, from the date of issuance or last payment of interest, up the date at which the security is valued. An active market is a market where transactions for assets or liabilities are carried out with sufficient frequency and volume in order to provide price information on an ongoing basis. The fair value of financial assets and liabilities that are not traded in an active market is determined through appraisal techniques determined by the price supplier or by the management of Grupo Aval’s entities. Appraisal techniques used for non-standardized financial instruments such as options, foreign exchange swaps and derivatives of the over-the-counter market, which include the use of interest rate or currency assessment curves built by providers and extrapolated to the specific conditions of the instrument being appraised, discounted cash flow analysis, options pricing models and other valuation techniques commonly used by market participants who rely mostly on market data and the least possible on specific data of entities. Grupo Aval may use models developed internally for financial instruments with no active markets. These models are usually based on valuation techniques and methods generally standardized in the financial sector. The valuation models are mainly used for appraising financial equity instruments not listed on the stock exchange, debt certificates and other debt instruments for which the markets were or have been inactive during the financial period. Some inputs of these models may not be observable in the market and are therefore estimated based on assumptions. The output of a model is always an estimate or approximation of a value that cannot be determined with certainty, and the valuation techniques used may not fully reflect all the factors relevant to the positions of Grupo Aval. Therefore, the appraisals are adjusted, if necessary, to allow for additional factors, including country risk, liquidity risks and counterparty risks. The fair value hierarchy has the following levels:
| ● | Level 1 inputs are quoted prices (unadjusted) in active markets for assets or liabilities identical to those which the entity can access as of the date of measurement.
| ● | Level 2 inputs are inputs different than quoted prices included in Level 1 that are observable for the asset or liability, whether directly or indirectly in non-active markets.
| ● | Level 3 inputs are unobservable inputs for the asset or liability.
The level in the fair value hierarchy within which fair value measurement is classified in whole is determined based on the input of the lowest level that is most significant for measuring its total fair value. For such purpose, the relevance of an input is assessed in connection with the measurement of the total fair value. Financial instruments that are listed in markets that are not deemed active, but which are valued based in accordance with quoted market prices, quotes from price vendors or alternative price sources supported by observable inputs, are classified in Level 2. If a fair value measurement uses observable inputs that require significant adjustments based on unobservable inputs, this measurement is classified as Level 3. The assessment of the importance of a particular input to the measurement of fair value in whole requires judgment, taking into account specific factors of the asset or liability. Determining what is deemed as ‘observable’ requires a significant judgment by Grupo Aval. Grupo Aval considers as observable data the market data which is already available, distributed or updated by the price suppliers, and it is reliable and verifiable, with no property rights, and provided by independent sources which are actively involved in the reference market. ​ 5.1 Measurements of Fair Value on a Recurring Basis Measurements of fair value on a recurring basis are those required or allowed in statement of financial position at the end of each accounting period. ​ ​ The following table presents an analysis, within the hierarchy of fair value, of Grupo Aval´s assets and liabilities (by class), measured at fair value as of December 31, 2024 and 2023, on a recurring basis. ​ December 31, 2024

These assets or liabilities primarily include impaired collateralized loans and non-current assets held for sale. The fair value of these assets which are classified as Level 3 are determined using pricing models, discounted cash flow methodologies, current replacement cost or similar techniques, using internal models or external experts with sufficient experience and knowledge of the real estate market or of assets being appraised. Generally, these appraisals are carried out by references to market data or based on the replacement cost when sufficient market data is not available. The following table presents Grupo Aval’s assets and liabilities, classified within the fair value hierarchy, which are measured on a nonrecurring basis as of December 31, 2024 and 2023 at fair value less cost of sale: ​

These Level 3 instruments include primarily investments in equity instruments, which are not publicly traded. In other cases, such as the Nexus and Pactia, the investments are valued using their unit value (Commercial appraisal). Given that observable prices are not available for these investments, the Contract Manager uses valuation techniques to obtain the fair value. ​ The following table presents the variables of the model used to calculate the sensitivity analysis, which is calculated taking as a reference the market value resulting from the valuation of the Group's properties, the Group's takes the calculation of two impacts cataloged as scenarios: ​ Scenario 1 contemplates the calculation taking the increase of the following variables: ​

The assumptions and inputs used in the calculation of the financial asset estimate were:
| ● | The expiration date of each concession contract.
| ● | The proportion of the expiry period left of each of the concession contracts in force.
| ● | Operational cash flows (only) of the assets under concession.
​ The components of the calculations are the following:
| ● | Free cash flow generated solely by assets under concession.
| ● | Expiry period of the concession.
| ● | Amount in - perpetuity of the Free Cash Flow (FCF) of the year, estimated factoring in a growth in the residual amount between 1% and 3% each year.
| ● | Current amount of the residual amount Weighted Average Cost of Capital (WACC), between 8.51% and 8.73% each year.
| ● | Financial income: annual adjustment of financial asset balance to WACC (*).
​ (*) Nominal WACC calculated under the Capital Asset Pricing Model (CAPM) methodology for each entity, updated annually. The following variables were used for determining the WACC:
| ● | Beta unlevered USA (Oil/Gas Distribution): Damodaran. (Unlevered Beta 0.64, 2023)
| ● | Risk Free Rate, Source: Geometric Average 1998-2023 of American bonds “T-Bonds”.
| ● | Market Return, Source: Geometric Average 1998-2023 Damodaran “Stocks” USA.
| ● | Market Premium: Market Return – Risk Free Rate
| ● | Country Risk Premium: Average last 5 years EMBI (Difference between 10-year Colombian sovereign bonds and 10 years “T-Bonds”). Damodaran.
| ● | Emerging Market: Equity Premium Emerging countries (Lambda - Damodaran)
​ Sensitivity analysis The following table includes a sensitivity analysis of the assumptions used by Promigas and its subsidiaries in the calculation of fair value of unconditional transfer rights of gas pipelines to Government entities at the expiration date of the contracts.

(*) Perpetuity growth rate in the case of concessions with renewal clauses that are highly likely to be exercised. ​ (3) Biological Assets Fair value of Grupo Aval subsidiaries “biological assets”, which correspond to agricultural activities related to biological assets (animals or plants), is estimated based on internal reports prepared by the companies who own such assets. Fair value of biological assets is determined using valuations performed by experienced internal professionals, using discounted cash flow models. Since no comparable market exist for the biological assets, given their nature, their fair value is determined using discounted cash flows models for each biological asset, based on estimated future quantities of crops, prices, harvesting costs, and maintenance and crop yields, among others, discounted using a risk-free rate adjusted by an appropriate risk premium. See note 15. The main assumptions used for determining the fair value of the principal biological assets are as follows: 1. Biological assets growing in rubber crops: The price of natural rubber used to calculate the 2025-2027 cash flows was forecasted based on the average of the last 3 years of the Technically Specified Rubber (TSR20) per ton January 2022 Ps. 0.38 (US$ 1,670/Ton), in order to reflect the behavior of the commodity for an entire economic cycle. Forecasted prices are adjusted annually based on the expected US inflation rate. ​ 2. Biological assets growing in African palm crops: The price of African palm oil (US$ per ton) used to calculate the 2025-2026 cash flows was forecasted based on the average price of palm oil since January 2023 Ps. 0.25 (US$ 1,111/Ton), in order to reflect the behavior of the commodity for an entire economic cycle. Forecasted prices are adjusted annually with the expected US inflation rate. ​ (4) Investment properties Investment properties are recognized at fair value, based on a valuation made at each year-end period using, as a basis, independent appraisal expert whose report is obtained and reviewed by management. While in the countries in which we operate, the frequency of transactions in the real state sector is low compared to other more developed markets, management believes there are enough references to assess the fair value of investment properties owned by Grupo Aval and its subsidiaries based on comparable market transactions (See note 15.3). ​ Fire-sales are excluded from the comparable transactions used to estimate the fair-value of investment properties. Management has reviewed the main assumptions used by the independent external appraisers (such as inflation, interest rates, etc.) and believes they are consistent with market conditions at each end of period. However, management believes that the estimation of the fair value of investment properties depends on significant judgment from the independent expert appraisers, and as such, there could be a significant probability that the actual price of sale of a property differs from its fair value. (See note 5.1) 5.4 Transfers between level 1, level 2 and level 3 of the fair value hierarchy The following table summarizes the transfer between fair value levels 1, 2 and 3 as of December 31, 2024. In general, transfers between Levels in the investment portfolios are due, fundamentally, to changes in the liquidity levels of the securities in the markets. ​

​ The following is a breakdown of how financial assets and liabilities accounted at amortized cost and are measured at fair value for disclosure purposes only. ​ (1) Debt securities at amortized cost Fair value of fixed income investments at amortized cost was determined using the dirty price given by the price supplier, securities in an active market and with a market price for the day of the valuation are classified as level 1; securities with no active market and/or with an estimated price (present value of the flows of a security, discounted with the reference rate and the corresponding margin) given by the supplier are classified as level 2 and level 3. ​ (2) Credit portfolio at amortized cost For credit portfolio at amortized cost, the fair value was determined using discounted cash flows models at zero coupon bond, taking into account the credit risk and its maturity; the process of valuation is deemed as level 3. Accounts receivable and payable are classified as short-term assets and liabilities; in consequence, their fair value is similar to their book value. ​ (3) Customer deposits The fair value of demand deposits is equal to their carrying value. For fixed-term deposits with maturities of less than 180 days, their fair value is deemed equal to their carrying value. For fixed-term deposits with maturities of more than 180 days, their fair value was estimated using the carrying discounted cash flow models and the interest rates offered by banks in accordance with their maturity. This is considered as a level 2 valuation. ​ (4) Financial obligations and other liabilities For financial liabilities and other short-term liabilities, the carrying value was considered to be similar to its fair value. The fair value of long-term financial liabilities was determined using the discounted cash flow model at interest rates free of risk adjusted by risk premiums of each entity. The fair value of outstanding bonds is determined according to quoted prices or estimated prices supplied by the price vendor. It is considered that this is a level 2 valuation. ​
