There is an exception to this rule that extends the maximum quota up to 25% (without guarantee) when it comes to loans to 4G infrastructure projects. These same limits apply to companies which are not part of Grupo Aval. ● Pursuant to article 2.1.2.1.8 of Decree 2555 of 2010, banks in Colombia have a lending limit of 30% of their regulatory capital with respect to loans granted to financial entities. These same limits apply all financial entities. ​ Foreign subsidiaries of Grupo Aval do not have any restriction to transfer dividends to the parent company. Lending operations in general have restrictions similar to those of banks in Colombia, as described above. ​ Grupo Aval and its subsidiaries do not have significant restrictions on their ability to access or use their assets and settle their liabilities other than those resulting from the supervisory frameworks within which subsidiaries of the financial sector operate. The supervisory frameworks require subsidiaries of the financial sector to keep certain levels of regulatory capital (see note 4.4) and liquid assets (see note 4.3), limit their exposure to other parts of Grupo Aval and its subsidiaries and comply with other ratios. 1.1 OTHER EVENTS ​ COVID-19 ​ Around the globe, 2021 was considered as a year for economic transition, in which countries around the world experienced a marked pick-up in their commercial activity, domestic demand and the subsequent inflationary pressures. According to the International Monetary Fund, or “IMF”, following the 3.1% contraction experienced in 2020, the World Output (GDP) increased 5.9% in 2021. When compared to 2019, the World GDP increased 2.6%. Colombia and Central America, the main markets where Grupo Aval operates were not the exception to this trend and benefited from a sharp recovery in their respective economies. ​ As a result of the abovementioned, monetary policy around the globe shifted towards a less expansionary stance. As such, monetary policy for the second half of 2021 was led by central banks discussing the possibility of tapering stimulus programs and starting hiking cycles of their reference rates. In connection with the banking activity, from which the Group derives the majority of income, this trend poses challenges for the coming year in terms of possible declines in intermediation spreads, slower growth of loans in the context of a less favorable credit cycle and decreases in the value of investment portfolios in fixed income and equity instruments. However, credit asset quality is expected to continue improving as compared to that seen in 2020, amidst the most critical part of the COVID-19 pandemic, which could favor an improvement of impairment loss needs. During 2021, Grupo Aval’s management continuously monitored the development of these trends as in 2020, evaluating any the adverse effects that may arise and affect the results of operations, the financial condition and the Group’s liquidity, and following up on measures that enabled reduced unfavorable impacts derived from the situation. ​ As of December 31, 2021 and up to the date of this report, the matters mentioned below have been assessed, and the impact has been recorded in the Group’s financial statements. During the period after the date of these financial statements and until the date of their issue, Grupo Aval’s management continued to monitor and address the effects on the Group’s operations and those of its customers. ​ Impairment of financial instruments - Loan portfolio, other accounts receivable and others ​ Financial instruments that are in the scope of IFRS 9 Expected Credit Loss model (loans, trade accounts other accounts receivable, debt instruments not measured at fair value through profit or loss, contract assets including concession agreements under financial asset model, lease receivables, financial guarantees and loan commitments) have been evaluated considering the impacts that COVID-19 continue to have on the ECL (Expected Credit Loss), due to measures adopted by the Governments in each of the countries and territories where the Group operates. ​ The impacts in relation to impairment of financial instruments in the Group entities are based on the following aspects: ​ ● ECL measurement, due to changes in the credit risk allocation of financial instruments, incorporating analysis of COVID ’ s effects and having an impact on the provision and due to the termination of the relief granted to a segment of debtors, going from a 12-month measurement (stage 1) to a measurement for the remaining life of the instrument (stages 2 and 3), for those assets in which it was determined that there was a significant increase in credit risk since their initial measurement. ​ ● Credit risk (risk of default), where the behavior observed has varied in accordance to the economic segments that comprise their loan portfolios, increasing in the case of clients whose businesses were negatively affected by COVID-19 pandemic and did not achieve a partial or full recovery of their activity during 2021. ​ ● The amount at risk (exposure at default), as some of the affected debtors have stopped making payments or are taking longer than usual to pay. ​ ● The estimated credit loss for those loans assessed individually, as a result of a reduction in the amount expected to be recovered in consideration of the COVID-19 impact. ​ ● Accordingly, to the effects of the coronavirus itself and the relief measures undertaken by the governments, including instructions to credit institutions to provide relief measures to customers in the countries where we operate, have an important role in ECL assessment. As a result, extension of payment terms to specific borrowers in particular classes of financial instruments do not automatically resulted in those instruments being considered to have suffered a significant increase in credit risk (SICR). To reflect COVID-19 effects in our models, the following overlays were made conducting a more detailed analysis of the risk and characteristics of certain clients: i) no stage improvement in obligations that requested relief and; ii) migration to Stage 2 of obligations identified as "high risk" as a result of COVID-19 specific impacts. ​ ● Macroeconomic factors considered in the development of scenarios and models for calculating the ECL, where most of the variables have shown a recovery while some others have deteriorated according to the effects that COVID-19 has had on the economy. ​ ECL calculation continues to incorporate updated projections of forward-looking information, in line with the effects of decisions that Governments continue taking in relation to COVID-19 and the prospects for economic recovery in some countries. The projections have been based on the best available information, considering the geographical areas where the Group operates, and the effects on the entities’ segments and portfolios which are exposed to different risks and situations. ​ When considering the forward-looking information based on macroeconomic variables, the Group updated the scenarios used (one-year projection) weighted by the probabilities assigned to them according on the expectations economics resulting from the information available as of December 31, 2021 (see note 4.1.5 Forward looking information). ​ The following table presents one-year projections for Colombia made in December 2020, compared to the official data for December 2021: ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 ​ Real Scenario ​ Scenario A Scenario B Scenario C Inflation 5.62% ​ 2.26% 2.69% 3.08% Interest rate 3.00% ​ 1.75% 2.25% 2.75% GDP Growth 10.60% ​ 3.89% 4.86% 5.85% Unemployment rate 11.00% ​ 16.31% 14.43% 12.90% ​ ​ The following table presents one-year projections for Guatemala made in December 2020, compared to the official data for December 2021: ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 ​ Real Scenario ​ Scenario A Scenario B Scenario C Inflation 3.07% ​ 5.31% 3.28% 2.52% Nominal interest rate variation (0.41%) ​ 0.04% (0.27%) (0.50%) GDP Growth 7.50% ​ 1.67% 4.20% 5.84% Devaluation (0.96%) ​ 1.16% (0.25%) (1.79%) ​ The following table presents one-year projections for Honduras made in December 2020, compared to the official data for December 2021: ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 ​ Real Scenario ​ Scenario A Scenario B Scenario C Inflation 5.32% ​ 3.34% 3.57% 2.54% Nominal interest rate variation (1.60%) ​ 0.20% (0.21%) (0.50%) GDP Growth 12.50% ​ 2.03% 3.94% 4.71% Devaluation 1.49% ​ 1.91% 0.92% (0.55%) ​ The following table presents one-year projections for El Salvador made in December 2020, compared to the official data for December 2021: ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 ​ Real Scenario ​ Scenario A Scenario B Scenario C Inflation 6.11% ​ 1.22% 0.23% (0.23%) Nominal interest rate variation (0.14%) ​ 1.10% 0.40% (0.08%) GDP Growth 10.30% ​ 1.96% 3.60% 4.69% ​ ​ The following table presents one-year projections for Nicaragua made in December 2020, compared to the official data for December 2021: ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 ​ Real Scenario ​ Scenario A Scenario B Scenario C Inflation 7.21% ​ 3.67% 2.78% 2.49% Nominal interest rate variation (0.86%) ​ 1.05% 0.11% (1.38%) GDP Growth 10.30% ​ (2.28%) 0.14% 2.12% ​ The following table presents one-year projections for Costa Rica made in December 2020, compared to the official data for December 2021: ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 ​ Real Scenario ​ Scenario A Scenario B Scenario C Inflation 3.30% ​ 2.22% 0.98% 0.75% Nominal interest rate variation (1.01%) ​ 2.28% 1.82% (0.01%) GDP Growth 7.60% ​ 0.93% 2.98% 4.27% Devaluation 4.53% ​ 5.22% 3.67% 2.19% ​ The following table presents one-year projections for Panamá made in December 2020, compared to the official data for December 2021: ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 ​ Real Scenario ​ Scenario A Scenario B Scenario C Inflation 2.62% ​ 1.89% 0.23% (0.29%) Nominal interest rate variation (0.09%) ​ 0.21% 0.02% (0.13%) GDP Growth 15.30% ​ 2.37% 4.04% 6.34% ​ The table below presents the total loss allowance balances for each portfolio as of December 31,2021 and 2020.

These instructions included, among others: (i) establishment of policies to identify clients subject to relief measures, (ii) payment extensions taking into consideration each client’s situation, affecting loans that were not past due for more than 30 days as of February 29, 2020 (without an increase in credit risk) and, (iii) client classification under relevant risk categories as of February 29, 2020 (credit scores reported to credit bureaus will remain unaltered for the duration of the extension period). ​ Moreover, according to External Circular 014 of March 30, 2020, the Superintendency of Finance established additional measures in order to protect clients under reliefs, including, among others, (i) a restriction to increase interest rates; (ii) the prohibiting capitalization of interest; and (iii) the prohibition to collect interests on other related fees, commissions or insurances. Furthermore, payment extensions were adjusted to include loans that were past due between 30 days and 60 days as of February 29, 2020 (without an increase in credit risk). ​ The measures established in External Circulars 007 and 014 were effective until July 31, 2020. ​ In Central America, at the regional level there were grace periods and payment deferrals in all the countries where we operate, following the guidelines of the relevant financial authorities, which were, to some extent, similar to the regulations enacted in Colombia. ​ Furthermore, the Superintendency of Finance issued External Circular 022 on June 30, 2020 creating the “Debtor Support Program” (in Spanish, Programa de Acompañamiento a Deudores PAD), which gives instructions on the treatment of debtors in the context created by the COVID-19 pandemic and allows the establishment of structural payment solutions by redefining the credit conditions of those debtors that have suffered a negative impact on their income or their ability to pay as a result of the COVID-19 pandemic. External Circular 022 was effective from August 1, 2020 until December 31, 2020. However, the Superintendency of Finance extended the application of the PAD until August 31, 2021, under the same terms of External Circular 022, due to the persistence of the COVID-19 situation. ​ The Superintendency instructed credit institutions to: adopt the PAD in order to apply structural measures for debtors affected by the COVID-19 pandemic, according to the analysis carried out by each entity, to recognize the new economic reality of debtors and to allow them to continue attending their payment obligations during the life of the loan. ​ Institutions had the authority to determine which segments of debtors they offered the measures provided for in that Circular, taking into consideration, among other aspects, the adverse cash flow impact as a result of the COVID-19 pandemic. In order to adopt differential measures for each of the segments of debtors defined in the program, at least three groups of debtors were established: ​ ● those debtors for which the financial entity had reasonable grounds to infer that they could continue to attend their payment obligations in the terms and as originally scheduled at the time of the beginning of the program. ● those debtors that had seen their income or payment capacity partially impacted and for which the entity had reasonable grounds to infer that, through a redefinition of the credit conditions, such debtor could continue to fulfil its payment obligations in the new agreed terms; and ● those debtors who temporarily faced a substantial or total impact on their income or ability to pay and for whom the entity had reasonable grounds to infer that the debtor would be able to overcome this impact. ​ The Superintendency also instructed credit institutions to: ​ ● adopt special measures for origination and qualification by risk level for micro, small, medium and other companies that are or will be in reorganization processes under the Colombian laws; ● grant new grace periods without capitalizing interest and without charging interest on other concepts which’s payment was deferred, such as handling fees and insurance; ● apply the redefinition of credit conditions, credit institutions may establish a self-management strategy for the debtor and / or contact him directly to present, in a simple way, the new conditions of his debt for acceptance. ​ In Central America, after granting the initial round of reliefs, the strategy of the subsidiaries consisted of restructuring certain loans to help its clients mainly through an extension of their term. Cases were analyzed to ensure the new conditions responded to the impact caused by the COVID-19 pandemic on the debtor’s income. ​ The actions taken by most of governments of the countries where we operate to provide relief to customers (companies or individuals) in 2020 and most of 2021, have ended. These strategies included, grace periods, the deferral of installments and the extension of terms. ​ The following table summarizes for all loan portfolio that received reliefs during 2021 and 2020, the balance at amortized cost before the application of relief per portfolio and the effects on the interest income of Grupo Aval of these reliefs, considering the recalculation of present values of the modified contractual cash flows discounted at the financial asset’s original effective interest rate: ​ Year ended on December 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ Consumer ​ Mortgage ​ Microcredit ​ Total Amortized cost before modification Ps. 29,961,397 Ps. 16,834,900 Ps. 13,763,005 Ps. 8,670 Ps. 60,567,972 Net modification loss ​ (18,895) ​ (8,819) ​ (6,213) ​ (12) ​ (33,939) ​ Year ended on December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ Consumer ​ Mortgage ​ Microcredit ​ Total Amortized cost before modification Ps. 43,637,334 Ps. 24,776,794 Ps. 14,411,716 Ps. 357,892 Ps. 83,183,736 Net modification loss ​ (13,230) ​ (82,971) ​ (36,873) ​ (2,034) ​ (135,108) ​ The governments of the countries in which the Group operates have not granted direct reliefs for banks to date. ​ ​ Impairment of assets - Goodwill, Property, Plant and Equipment and Intangibles (in

Disclosure of voluntary change in accounting policy [abstract]
BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 – BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The consolidated financial statements of Grupo Aval have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). The consolidated financial statements have been prepared on the basis of historical cost, except for financial assets at Fair Value Through Profit or Loss (“FVTPL”), at Fair Value Through Other Comprehensive Income (“FVOCI”), derivative financial instruments, investment properties, non-current assets held for sale and biological assets which are measured at fair value. Additionally, non-current assets held for sale are measured at the lower value of their carrying value at the time of transfer and fair value, minus estimated costs of disposal and employee benefits which are measured at the present value of the defined benefit obligation (see note 2.22). The consolidated financial statements were authorized for issuance by the Audit Committee on April 19, 2022. The following are the main accounting policies applied in preparing the Consolidated Financial Statements of Grupo Aval as of December 31, 2021, 2020 and 2019. 2.1 Basis of preparation a) The Consolidated Financial Statements are prepared as follows: ​ ● The Consolidated Statement of Financial position presents the company´s assets and liabilities based on liquidity since it provides reliable and more relevant information than separate current and non-current classifications. ​ ● The Consolidated Statements of Income and Other Comprehensive Income are presented separately. The Consolidated Statement of Income is presented according to the function of expenses, as this method provides reliable and more relevant information. ​ ● The Consolidated Statement of Cash Flows is presented using the indirect method. Accordingly, net cash flows from operating activities are determined by reconciling net income before tax expense, with the effects of non-cash items, net changes in assets and liabilities from operating activities, and for any other effects that are not classified as investing or financing activities. Revenues and expenses due to interest received and paid are part of operating activities. ​ b) Consolidated Financial Statements ​ Grupo Aval prepares its Consolidated Financial Statements incorporating its controlled entities. Grupo Aval controls an investee if and only if it complies with the following elements: ​ ● Power over the investee entitling Grupo Aval to direct any relevant activities that significantly affect the investee's performance. ● Exposure, or rights to variable returns from its involvement with the investee. ● Ability to affect those returns through its power over the investee. ​ Grupo Aval carries out of all its contractual relationships, for the year 2021, no new entities were identified to be consolidated and with the year 2020 in the evaluation carried out a business combination was identified (see note 35). ​ The financial statements for Grupo Aval´s subsidiaries are included in the consolidated financial statements since the date on which Grupo Aval acquires control or following control until the date on which control is lost. ​ During the consolidation process, Grupo Aval combines the assets, liabilities and profits or losses of those entities under control, previously aligning the accounting policies in all the subsidiaries and translating its financial statements to Colombian Peso. This process includes eliminating intra-group balances and transactions and any unrealized and realized income and expense (except for foreign currency translation gains or losses and those taxes which are not subject to elimination) arising from intra-group transactions. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment. Non-controlling interests are presented under total equity in the Consolidated Statement of Financial Position of Grupo Aval separately from equity attributable to owners of the parent company. For consolidation purposes, the Statements of Financial Position and Income of entities with a functional currency different form Grupo Aval´ are translated to Colombian pesos as follows: ● Assets and liabilities are translated at the closing exchange rate at the reporting date; ● Income, expense and cash flows are translated at the corresponding month’s average exchange rate since they approximate the exchange rates of each specific transaction; ● All resulting exchange differences are recognized in other comprehensive income and accumulated in the foreign currency translation reserve, except to the extent that the translation difference is allocated to non-controlling interests. ​ c) Investments in associates ​ Associates are companies in which Grupo Aval has significant influence but not control and are accounted for under the equity method. They are presented in the statement of financial position as “Investments in associates and joint ventures” (see Note 2.1 “d Joint arrangements”). Grupo Aval exercises significant influence over another entity if it owns, directly or indirectly, 20% or more of the voting power of the investee, unless it is clearly evidenced that such influence does not exist. They are initially recognized at cost, which includes transaction costs. Subsequent to initial recognition, the Consolidated Financial Statements include the Grupo Aval’s share of the profit or loss and OCI of equity accounted investees, until the date on which significant influence or joint control ceases. ​ Dividends received from associates and joint ventures are recognized as a lower value in the carrying amount of the investment. ​ In the case that Grupo Aval´s share of losses in an equity-accounted investment equals or exceeds its interest in the entity, including any other unsecured long-term receivables, Grupo Aval does not recognize further losses, unless it has incurred obligations or made payments on behalf of the other entity. ​ Unrealized gains on transactions between Grupo Aval and its associates are eliminated to the extent of Grupo Aval’s interest in these entities. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. ​ Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by Grupo Aval. ​ The carrying amount of associates are tested for impairment. ​ d) A joint arrangement is one in which two or more parties have joint control of the arrangement. Joint arrangements are divided into joint operations or joint ventures. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement, under joint operations the parties having joint control of the agreement have rights to the assets and obligations to the liabilities relating to the agreement. Under joint ventures, the parties having joint control, are entitled to the net assets of the agreement. Grupo Aval recognizes joint operations in the consolidated financial statements based on their proportional and contractual participation in each of the assets, liabilities and profit or loss of the contract or entity wherein the agreement is held. Grupo Aval recognizes joint ventures through the equity method, in the same manner as investments in associates. ​ ​ 2.2 Functional and presentation currency ​ Considering that the majority of the Group´s business activities as well as the generation and use of cash is in Colombian pesos, the Colombian peso is the currency that most accurately represents the economic environment of Grupo Aval’s operations, both for the consolidated financial statements and for the parent company. Foreign entities have functional currencies different from the Colombian peso, which are translated to Colombian pesos for presentation purposes. The main functional currency these foreign entities is the US dollar. ​ ​ 2.3 Transactions in foreign currencies ​ Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the prevailing exchange rate at the reporting date. Non-monetary assets and liabilities denominated in foreign currencies in terms of historical costs are measured using the exchange rate at the transaction date. Financial instruments measured at fair value are converted using the exchange rate at the date the fair value was determined. Profits or losses resulting from the translation process are recognized in profit or loss, except for financial instruments designated as hedging instruments. ​ As of December 31, 2021 and 2020, the representative market rates as computed and certified by the Superintendency of Finance (for the U.S. dollar which is the most representative foreign currency for Grupo Aval´s transactions) were Ps. 3,981.16 and Ps. 3,432.50 per U.S. $1, respectively. ​ ​ 2.4 Operating segments ​ An operating segment is a component of an entity which: ​ a) Engages in business activities from which it can earn revenue and incur expenses (including revenue and expenses from transactions with other components of the same entity); b) Operating profit or losses are regularly reviewed by the chief operating decision maker, who decides on the resources allocation to the segment and assesses its performance and. c) Discrete financial information is available, Segment results that are reported to the CODM include items that are directly attributable to a segment as well as those that can be allocated on a reasonable basis. Management evaluates regularly the performance for each segment; Grupo Aval discloses information separately for each identified operating segment, meeting any of the following quantitative thresholds: a) The segment´s reported revenue from the ordinary activities, including revenue from external customers as well as revenue from intersegment transfers, is equal or greater than 10% of the revenue of combined ordinary activities, internal and external, of all operating segments. b) The amount of the segment´s reported net income is, in absolute terms, equal or greater than 10% of the amount greater of: (i) the combined reported net income of all the segments not reporting a loss; and (ii) the reported combined loss of all segments of the operations with incurred losses. c) The segment´s assets are equal to or greater than 10% of the combined assets of all segments of the operation. The information regarding other activities of the business of operating segments that do not have to be reported is combined and disclosed within the category of “Others”. ​ ​ ​ ​ 2.5 Financial assets and financial liabilities ​ i. Recognition and initial measurement ​ Grupo Aval initially recognizes loans and advances, deposits, debt securities issued and subordinated liabilities on the date on which they are originated. All other financial instruments (including regular-purchases and sales of financial assets) are recognized on the trade date, which is the date in which Grupo Aval becomes a party to the contractual provisions of the instrument. A financial asset or financial liability is initially measured at fair value. Additionally, for instruments measured at amortized cost or Fair Value Through Other Comprehensive Income (“FVOCI”), transaction costs are added if directly attributable to its acquisition or issuance. ii. Classification ​ Financial assets ​ On initial recognition, a financial asset is classified as: amortized cost, Fair Value Through Other Comprehensive Income (“FVOCI”) or Fair Value Through Profit or Loss (“FVTPL”). ​ A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL: ● The asset is held within a business model in which the objective is to hold assets to collect contractual cash flows; and ● The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. A debt instrument is measured at FVOCI only if it meets both of the following conditions and is not designated as at FVTPL: ● The asset is held within a business model whose objective is achieved both by collecting contractual cash flows and selling the financial asset; and ● The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. On initial recognition of an equity investment that is not held for trading, Grupo Aval may irrevocably elect to present subsequent changes in fair value in Other Comprehensive Income (“OCI”). This election is made on an investment-by-investment basis. All other financial assets are classified and measured at FVTPL. Business model assessment ​ Grupo Aval makes an assessment of the objective of a business model in which an asset is held at a portfolio level because this best reflects the way the business is managed, and information is provided to management. The information considered includes: ​ ● The established policies and objectives for the portfolio and their actual application. In particular, whether management’s strategy focuses on earning contractual interest revenue, maintaining a particular interest rate profile, matching the duration of the financial assets to the duration of the liabilities that are funding those assets; ● How the performance of the portfolio is evaluated and reported to Grupo Aval’s management; ● The risks that affect the performance of the business model (and the financial assets held within that business model) and how those risks are managed; and ● The frequency, volume and timing of sales of financial assets in prior periods, the reasons for such sales and its expectations about future sale activity. However, information about sales activity is not considered in isolation, but as part of an overall assessment of how Grupo Aval’s stated objective for managing the financial assets is achieved and how cash flows are realized. Financial assets that are held for trading, for which performance is evaluated on a fair value basis are measured at FVTPL because their objective is neither to collect contractual cash flows nor to collect contractual cash flows and sell the financial assets. ​ Assessment whether contractual cash flows are solely payments of principal and interest (SPPI) ​ For the purposes of this assessment, “principal” is defined as the fair value of the financial asset on initial recognition. “Interest” is defined as consideration for the time value of money and for the credit risk associated with the principal amount outstanding during a particular period of time and for other basic lending risks (e.g. liquidity risk and administrative costs), as well as profit margin. ​ In assessing whether the contractual cash flows are solely payments of principal and interest (SPPI), Grupo Aval considers the contractual terms of the instrument. This includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet this condition. Upon assessment Group Aval considers: ​ ● Contingent events that would change the amount and timing of cash flows; ● Leverage covenants; ● Prepayment and extension terms; ● Terms that limit Grupo Aval’s claim to cash flows from specified assets; and ● Features that modify consideration of the time value of money. ​ Interest rates on certain commercial and consumer loans originated by Grupo Aval are pegged to standard variable rates generally used in each country where Grupo Aval operates and includes a spread. In Colombia, the standard variable rates are based on the DTF (rate interest calculated as the average for time deposits)s or the interbank rate (in Spanish Interés Bancario de Referencia), or “IBR” rates, both of which are calculated weekly by the Central Bank based on information collected from the Colombian financial system, plus a spread, and in the case of loans in foreign currency issued in Colombian entities and in other countries Grupo Aval uses LIBOR interest rates plus a spread. See Note 4 – “Interest rate benchmark reform”. ​ In these cases, Grupo Aval assesses whether the discretionary feature is consistent with the SPPI criteria by considering a number of factors, including whether: ​ ● Borrowers are able to prepay the loans without significant penalties, ● Market competition ensures that interest rates are consistent between banks, and ● Any regulatory or customer protection framework is in place that requires banks to treat customers fairly. A prepayment feature is consistent with the SPPI criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable compensation for early termination of the contract. ​ In addition, a prepayment feature is treated as consistent with this criterion if a financial asset is acquired or originated at a premium or discount to its contractual par amount, and the prepayment amount substantially represents the contractual par amount plus accrued (but unpaid) contractual interest (which may also include reasonable compensation for early termination), and the fair value of the prepayment feature is insignificant upon initial recognition. ​ Financial liabilities ​ Grupo Aval classifies its financial liabilities, other than derivatives, financial guarantees and loan commitments, as measured at amortized cost. ​ iii. Reclassifications ​ ​ Financial assets ​ Financial assets are not reclassified subsequent to their initial recognition, except in the period after Grupo Aval’s entities changes their business model for managing financial assets. iv. Derecognition ​ ​ Financial assets ​ Grupo Aval derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire (see also (v)), or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which Grupo Aval neither transfers nor retains substantially all of the risks and rewards of ownership but it does not retain control of the financial asset. ​ At derecognition of a financial asset, the difference between the carrying amount of the asset (or the carrying amount allocated to the portion of the asset derecognized) and the sum of (i) the consideration received (including any new asset obtained less any new liability assumed) and (ii) any cumulative gain or loss that had been recognized in OCI is recognized in profit or loss. Any cumulative gain/loss recognized in OCI in respect of equity investment securities designated as at FVOCI is not recognized in profit or loss on derecognition of such securities, as explained in (2.10). Any interest in transferred financial assets that qualify for derecognition that is created or retained by Group Aval is recognized as a separate asset or liability. Grupo Aval enters into transactions whereby it transfers assets recognized on its statement of financial position but retains either all or substantially all of the risks and rewards of the transferred assets or a portion of them. In such cases, the transferred assets are not derecognized. Examples of such transactions are securities lending and sale-and-repurchase transactions. When assets are sold to a third party with a concurrent total rate of return swap on the transferred assets, the transaction is accounted for as a secured financing transaction similar to sale-and repurchase transactions, given that Grupo Aval retains all or substantially all of the risks and rewards of ownership of such assets. In transactions in which it neither retains nor transfers substantially all of the risks and rewards of ownership of a financial asset and it retains control over the asset, Grupo Aval continues to recognize the asset to the extent of its continuing involvement, determined by the extent to which it is exposed to changes in the value of the transferred asset. Financial liabilities ​ Grupo Aval derecognizes a financial liability when its contractual obligations are discharged or cancelled or expire. ​ ​ v. Modifications of financial assets and financial liabilities ​ Financial assets ​ If the terms of a financial asset are modified, then Grupo Aval assesses whether the cash flows of the modified asset are substantially different. ​ If the cash flows are substantially different, the contractual rights to cash flows from the original financial asset are deemed to have expired. In that case, the original financial asset is derecognized (see (iv)) and a new financial asset is recognized at fair value plus any eligible transaction costs. Any fees received as part of the modification are accounted for as follows: ● Fees that are considered in determining the fair value of the new asset and fees that represent reimbursement of eligible transaction costs are included in the initial measurement of the asset; and ● Other fees are included in profit or loss as part of the gain or loss on derecognition. ​ If cash flows are modified when the borrower is in financial distress, the objective of the modification is usually to maximize recovery of the original contractual terms rather than to originate a new asset with substantially different terms. If Group Aval plans to modify a financial asset in a way that would result in foregoing of cash flows, it considers whether a portion of the asset should be written off before the modification takes place (see below for write‑off policy). This approach impacts the result of the quantitative evaluation and means that the derecognition criteria are not usually met in such cases. ​ If the modification of a financial asset measured at amortized cost or FVOCI does not result in derecognition of the financial asset, then Grupo Aval recalculates the gross carrying amount of the financial asset using the original effective interest rate of the asset and recognizes the resulting adjustment as a recovery or impairment in the Consolidated Statement of Income. For variable-rate financial assets, the original effective interest rate used to calculate the modification gain or loss is adjusted to reflect current market terms at the time of the modification. Any costs or fees incurred, and fees received as part of the modification are incorporated into the gross carrying amount of the modified financial asset and are amortized over the remaining term of the modified financial asset. ​ Financial liabilities ​ Grupo Aval derecognizes a financial liability when its terms are modified, and the cash flows of the modified liability are substantially different. In this case, a new financial liability based on the modified terms is recognized at fair value. The difference between the carrying amount of the financial liability extinguished and the new financial liability with modified terms is recognized in the Consolidated Statement of Income. ​ If the modification of a financial liability measured at amortized cost does not result in derecognition of the financial liability, then Grupo Aval first recalculates the gross carrying amount of the financial liability using the original effective interest rate of the liability and recognizes the resulting adjustment as interest expense in the Consolidated Statement of Income. For variable-rate financial assets, the original effective interest rate used to calculate the modification gain or loss is adjusted to reflect current market terms at the time of the modification. Any costs or fees incurred, and fees received as part of the modification are incorporated into the gross carrying amount of the modified financial liability and are amortized over the remaining term of the modified financial liability. ​ vi. Offsetting of financial assets and liabilities ​ Financial assets and liabilities are offset, and the net amount is recognized in the consolidated statement of financial position, when there is a legally enforceable right to offset recognized amounts and management intends to settle them on a net basis or to realize the asset and settle the liability simultaneously. Income and expenses are presented on a net basis only when permitted under IFRS, or for gains and losses arising from a group of similar transactions such as Grupo Aval’s trading activity. ​ vii. Fair value measurement ​ “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 in the principal or, in its absence, the most advantageous market to which Grupo Aval has access at that date. ​ Grupo Aval measures the fair value of an instrument using the quoted price in an active market for that instrument. A market is regarded as active if transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. ​ If there is no quoted price in an active market, Grupo Aval uses valuation techniques that maximize the use of relevant observable inputs and minimize the use of unobservable inputs. The chosen valuation technique incorporates all of the factors that market participants would take into account in pricing a transaction. ​ The best evidence of the fair value of a financial instrument on initial recognition is normally the transaction price – i.e. the fair value of the consideration given or received. If Grupo Aval determines that the fair value on initial recognition differs from the transaction price and the fair value is evidenced neither by a quoted price in an active market for an identical asset or liability nor based on a valuation technique for which any unobservable inputs are deemed to be insignificant in relation to the measurement, then the financial instrument is initially measured at fair value, adjusted to defer the difference between the fair value on initial recognition and the transaction price. Subsequently, that difference is recognized in the Consolidated Statement of Income on an appropriate basis over the life of the instrument but no later than when the valuation is wholly supported by observable market data or the transaction is closed out. ​ Portfolios of financial assets and financial liabilities that are exposed to market risk and credit risk, managed by Grupo Aval on the basis of the net exposure to either market or credit risk are measured on the basis of a price that would be received to sell a net long position (or paid to transfer a net short position) for the particular risk exposure. Portfolio-level adjustments – e.g. bid-ask adjustment or credit risk adjustments that reflect the measurement on the basis of the net exposure – are allocated to the individual assets and liabilities on the basis of the relative risk adjustment of each of the individual instruments in the portfolio. ​ The fair value of a financial liability with a demand feature (e.g. a demand deposit) is no less than the amount payable on demand, discounted from the first date on which the amount could be required to be paid. ​ Grupo Aval recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period during which the change has occurred. See Note 5. ​ viii. Repurchase agreements and reverse repurchase agreements ​ Purchases of financial instruments under a non-optional resale agreement are measured at fair value and recognized as financial assets in the consolidated statement of financial position under interbank and overnight funds. ​ The excess of the purchase prices over the resale prices is recognized as interest income over the contractual term. ​ Sales of financial instruments under a non-optional repurchase agreement are measured at fair value and recognized as liabilities in the consolidated statement of financial position under Interbank borrowings, overnight funds and borrowings from banks and others. ​ The excess of the sales prices over the repurchase prices is recognized as interest expense over the contractual term. ​ Retained interests (i.e. the assets that collateralize the repurchase agreements) are primarily classified as fair value through OCI and measured at fair value. ​ ix. Impairment of financial assets Grupo Aval recognizes loss allowances for Expected Credit Losses – (“ECL”) on the following financial instruments that are not measured at FVTPL: ● Debt investment instruments; ● Loans and receivables; ● Financial guarantee contracts issued; ● Loan commitments issued, and ● Other accounts receivable No credit impairment loss is recognized on equity investments. ​ Grupo Aval measures loss allowances at an amount equal to lifetime ECL (Stage 2 and stage 3), except the following cases, for which they are measured as 12-month ECL (Stage 1): ● Debt investment securities that are determined to have low credit risk at the reporting date; and ● Other financial instruments (other than loans and lease receivables) on which credit risk has not increased significantly – (“SICR”) since their initial recognition. ​ Grupo Aval considers a financial asset is classified as a low credit risk asset if the issuer is related to an investment grade credit rating. ​ 12-month ECL is the portion of ECL that results from default events on a financial instrument that are possible within the 12 months after the reporting date. ​ See the detail of the requirement actions as result of Covid-19 in note 1.1 “Other events” ​ Measurement of ECL ​ Measurement of ECL is described in Note 4(4.1.5 Amounts arising from ECL). ​ Modified Financial Assets ​ If the terms of a financial asset are renegotiated or modified or an existing financial asset is replaced with a new one due to financial distress of the borrower, an assessment is made of whether the financial asset should be derecognized (see (iv)) and ECL are measured as follows: ● If the restructuring is not expected to result in derecognition of the existing asset, then the expected cash flows arising from the modified financial asset are included in calculating the cash shortfalls from the existing asset (see Note 4(4.1.1)). ● If the restructuring is expected to result in derecognition of the existing asset, then the expected fair value of the new asset is treated as the final cash flow from the existing financial asset at the time of its derecognition. This amount is included in calculating the cash shortfalls from the existing financial asset that are discounted from the expected date of derecognition to the reporting date using the original effective interest rate of the existing financial asset. ​ Credit-impaired financial assets ​ At each reporting date, Grupo Aval assesses whether financial assets carried at amortized cost and at FVOCI are credit-impaired. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. ​ Evidence that a financial asset is credit-impaired includes the following observable data: ● Significant financial difficulty of the borrower or issuer; ● A breach of contract such as a default or past due event; ● The restructuring of a loan or advance by Grupo Aval on terms that Grupo Aval’ entities would not consider otherwise; ● It is becoming probable that the borrower will enter bankruptcy or other financial reorganization; or ● The disappearance of an active market for a security because of financial difficulties. A loan that has been renegotiated due to a deterioration in the borrower’s condition is usually considered to be credit-impaired unless there is evidence that the risk of not receiving contractual cash flows has decreased significantly and there are no other indicators of impairment. In addition, a loan different to mortgage that is overdue for 90 days or more is considered impaired. In making an assessment of whether an investment in sovereign debt is credit-impaired, Grupo Aval considers the following factors. ● The market’s assessment of creditworthiness as reflected in the bond yields. ● The rating agencies’ assessments of creditworthiness. ● The country’s ability to access the capital markets for new debt issuance. ● The probability of debt being restructured, resulting in holders suffering losses through voluntary or mandatory debt forgiveness; and ● The international support mechanisms in place to provide

Disclosure of risk management [abstract]
RISK MANAGEMENT	NOTE 4 – RISK MANAGEMENT Grupo Aval and its subsidiaries in the financial sector, Banco de Bogotá, Banco de Occidente, Banco AV Villas, Banco Popular, BAC Holding, MFH, Corficolombiana and Porvenir manage risk pursuant to the applicable regulations in each country where they operate and according to Grupo Aval’s internal policies. The risk framework requires that strong risk management practices are integrated in key processes across Grupo Aval, with a goal of ensuring risks are appropriately considered, evaluated and responded to in a timely manner. Grupo Aval employs a risk management process, that aims to identify, measure, monitor and control, as part of the daily activities, all the risks that Grupo Aval manages. Lines of Defense: in addition to the role of Executive Officers in managing risk, management has ownership and accountability across the three lines of defense: (1) First Line: Business Units, (2) Second Line: mainly concentrated in the Independent Risk Management units and (3) Third line: Corporate Audit. ● Business Units: Include the business lines as well as the Technology and Operations areas which are responsible for appropriately assessing and effectively managing all the risks associated with their processes. ● Independent Risk Management Units: Risk management areas include risk management and compliance departments. Grupo Aval has other control functions that are not part of these areas but are key in the risk mitigation of non-financial risks, including legal, human resources and certain activities within the financial and administrative processes. ● Corporate Audit: Corporate audit maintains its independence from the first and second lines by reporting directly to the Audit Committee or the Board. Corporate Audit provides independent assessment and validation through testing of key processes and controls across Grupo Aval. The following sections outline the key risks that are inherent in business activities of the subsidiaries in the financial sector: Financial risks i) Credit risk: the risk of financial loss if a debtor fails to meet its contractual obligations. ii) Market risk: the risk of loss arising from potential adverse changes in the value of the subsidiaries in the financial sector assets and liabilities or future results, resulting from changes in market variables such as interest rates, foreign exchange rates, equity prices, commodity prices, implied volatilities or credit spreads; this includes the structural interest rate and foreign exchange risks. iii) Liquidity risk: the risk of being unable to meet contractual and contingent obligations or that the subsidiaries in the financial sector do not have the appropriate amount, composition and tenor of funding and liquidity to support the financial assets and liabilities requirements (funding liquidity risk). Also includes the capability to manage its investment portfolio in terms of liquidity, duration and currency (market liquidity risk). iv) Interest rate risk: it is the current or potential risk to equity and profits that arise from adverse movements in interest rates, which affect the positions of the banking book. Additionally, the risk areas are responsible of supporting capital management by determining risk levels of the calculation of capital adequacy requirements, impact assessment of the risk materialization on compliance with capital levels and determine the levels of risk appetite. Objective and general guidelines of financial risk management Grupo Aval’s and its subsidiaries of the financial sector objective is to maximize returns for its investors, through proper risk management. The guiding principles of risk management at Grupo Aval are as follows: a) Make risk management a part of every institutional process. b) Collective decision making for commercial lending of significant amounts. c) Extensive and in-depth industry and market knowledge, as a result of the leadership and experienced, stable and seasoned senior management. d) Clear risk management policies based on a top-down approach with respect to: ● Compliance with know-your-customer policies. ● Commercial loans credit structure based on a clear identification of sources of repayment and of cash flow generation capacity of the borrower. e) Use of similar credit analysis tools for analysis across Grupo Aval’s subsidiaries of financial sector. f) Diversification of the commercial loan portfolio with respect to industries and economic groups. g) Specialization in consumer product niches. h) Extensive use of continuously updated scoring models and credit ratings updated permanently to ensure quality growth of consumer loans with high credit quality. i) Conservative policies in terms of: ● trading portfolio composition with bias towards lower volatility instruments, ● proprietary trading position, and ● the variable compensation for the trading staff. j) Control the position-level based on market risk sensitivities (such as VaR, DV01, Delta, Rho and Vega) and credit risk exposures by counterparties. k) Concentration and diversification limits which are based on market liquidity and volatility, operational capacity, valuation and credit quality of counterparties. l) Control and follow up the funding and liquidity risk with independent oversight. This includes setting limits related with high quality liquid assets and maturity concentration of financial liabilities among others. m) Ensuring compliance with regulatory limits and reviewing how the current and projected strategy can affect those limits. n) Use of our market presence in the identification and implementation of best practices for operational risk management. ​ Main premises for risk management Grupo Aval´s risk culture is based on the principles indicated in the section above and they are transmitted to all subsidiaries of the financial sector and business units. The strategy related with risk management is supported by the following guidelines: a) In all of Grupo Aval´s subsidiaries of the financial sector, the risk function is independent of the business units. The segregation of functions between the business areas and the risk areas in charge of risk measurement analysis, control and reporting, provide enough independence and autonomy for proper risk control. b) The decision-making process at the subsidiaries of the financial sector requires that transactions of significant amounts are sent to decision centers such as risk committees. The frequency of meetings of these committees ensures a high degree of agility regarding the resolution of proposals and continuous participation of senior management for management the different risks. c) Grupo Aval has corporate policies for the risk to which it is exposed. The business and risk units of Grupo Aval and its subsidiaries of the financial sector hold orientation meetings based on approaches to risk that are consistent with Grupo Aval´s risk culture. d) Grupo Aval has implemented a risk system that is updated on a regular basis to address new conditions in the markets and the risks to which Grupo Aval is exposed. e) There are adequate information systems to monitor risk exposure, to ensure compliance and approval policies and, if necessary, to implement proper corrective actions. f) Key risks are analyzed on a regular basis, not only when risks materialize or when problems occur during the normal course of business but in a continuous process of risk management. g) Grupo Aval and its subsidiaries of the financial sector have training courses on risk culture for all hierarchy levels in the organization. h) A risk culture integrated throughout the organization, consisting of a series of attitudes, values, skills and guidelines to action. Interest rate benchmark reform According to the Financial Conduct Authority (FCA) announcement which informed the future termination or loss of representativeness of the LIBOR reference rates starting on December 31, 2021 with some references until completing the total of 35 references in June 2023, the entities that use these rates worldwide are forced to transfer the current positions that were indexed to these references, towards new reference interest rates that maintain the representativeness and depth that the LIBOR rates used to have. Grupo Aval and its subsidiaries have not been immune to this phenomenon and even though the exposure is insignificant concerning other rates, there remains in its Entities a portfolio of credits, loans, deposits, and derivative contracts indexed at LIBOR rates, for which said Entities have been required to design and execute transition plans that allow them to identify the operational, commercial, legal and technological aspects to be taken into account to maintain their commercial relations and representativeness in the markets where they operate. Grupo Aval have stablished several guidelines in search of adoption best practices to ensure an adequate transition to new reference rates regarding to shape a governance structure, to stablish a project roadmap with defined timelines and milestones, to line up risk management function of the entity with all the impacted front-line processes, to define a specific group to coordinate the transition plan with appropriate high-level oversight and identify and manage possible financial impacts and operational gaps. ​ The LIBOR Working Group periodically reports to the Assets and Liabilities Committee (ALCO) about the progress of the transition plan, as well as the policies, guidelines, and procedures related to the follow-up and adoption of the ARRC 1 For IBOR indexed contracts that expire after the LIBOR rate expected cessation, the LIBOR Working Group has established policies to modify the contractual terms. These amendments include the addition of fallback clauses or the replacement of the LIBOR rate with an alternative benchmark rate. The LIBOR Working Group implemented adherence to the ISDA Amendment and Protocols with this signing, the legal (contractual) risk of the transition for derivative contracts was eliminated, defining the replacement of the LIBOR rate by SOFR plus a fixed spread. Each entities LIBOR Working Group has established policies regarding not closing new operations, or operations extensions at the Libor rate and initiating disbursements tied to the alternative rates and as an alternative to the transition, those in the short term and that will not have operations of repricing may be worked at a fixed rate, PRIME rate and in some cases for a smaller amount at other local rates in US dollars. As well, policies have been created so that portfolio operations are disbursed at a fixed rate, and in the event of a repricing, these may be tied to the Libor rate as long as their maturity date does not exceed June 2023. Once the technological developments, disbursements tied to the new reference rate will begin. No operations tied to LIBOR are carried out in other currencies. To date, no additional provisions have been estimated regarding the transition to new reference rates in any of the jurisdictions. The LIBOR Working Group monitors the LIBOR's progress transition to the new benchmark rates by reviewing the total amounts of contracts that have yet to transition to an alternative benchmark rate and the amounts of such contracts that exclude a fallback clause appropriate. A contract is considered to have not yet transitioned to an alternative reference rate when the interest under the contract is indexed to a reference rate that is still subject to LIBOR reform, even if it includes a fallback clause that addresses the LIBOR's rates cessation. On March 2021, the Financial Conduct Authority (FCA), as the ICE regulator (Intercontinental Exchange London Interbank Offered Rate, or the administering authority of LIBOR), announced that after December 31, 2021, the LIBOR references for the Pound Sterling, the Euro and the references for dollars one-week and two-month Americans will no longer be provided or will no longer be representatives. US dollar references will remain unprovided or no longer proxies after June 30, 2023. As follows, the amount of the contracts that Grupo Aval and its subsidiaries have indexed to LIBOR rates that will expire in June 2023 and the amount of the contracts that have included fallback clauses for the December 31, 2021 and 2020 cut-off are shown below: ​ ​ ​ ​ Non-derivative financial assets and liabilities. During 2021 and 2020, the Group had the following LIBOR exposures concerning non-derivative financial assets and loan portfolio subject to IBOR benchmarks.

Credit Risk	Financial Risk Review ​ 4.1 Credit Risk 4.1.1 Consolidated Credit Risk Exposure Grupo Aval´s subsidiaries are exposed to credit risk, consisting of the risk of financial loss as a result of the failure of the debtor to meet its contractual obligations in financial transactions on a timely and complete manner. Exposure to credit risk for Grupo Aval and its subsidiaries is a result of credit activities and transactions with counterparties. The maximum exposure to credit risk of Grupo Aval, at a consolidated level is reflected in the carrying value of financial assets in the statement of financial position of Grupo Aval as of December 31, 2021, and 2020 as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets December 31, 2021 December 31, 2020 Cash and cash equivalents (**) ​ Ps. 30,245,268 ​ Ps. 27,687,525 Trading investments in debt securities ​ ​ 4,741,287 ​ ​ 4,780,993 Investments in debt securities mandatorily at FVTPL ​ ​ — ​ ​ 7,385 Investments in debt securities at FVOCI ​ ​ 37,493,866 ​ ​ 28,966,356 Investments in debt securities at amortized cost ​ ​ 5,775,070 ​ ​ 5,580,128 Derivatives instruments ​ ​ 1,162,909 ​ ​ 1,133,924 Hedging derivatives ​ ​ 44,248 ​ ​ 156,220 Loans ​ ​ ​ ​ Commercial ​ ​ 122,027,804 ​ ​ 110,986,938 Consumer ​ ​ 76,889,145 ​ ​ 65,835,457 Mortgage ​ ​ 29,120,316 ​ ​ 24,558,771 Microcredit ​ ​ 317,739 ​ ​ 372,321 Interbank and overnight funds ​ ​ 3,218,433 ​ ​ 4,693,678 Other accounts receivable FVTPL ​ ​ 3,228,480 ​ ​ 2,958,385 Other accounts receivable at amortized cost ​ ​ 16,181,527 ​ ​ 12,381,009 Total financial assets with credit risk ​ Ps. 330,446,092 ​ Ps. 290,099,090 Financial instruments with credit risk outside of the statement of financial position at its nominal value ​ ​ ​ ​ Financial guarantees and letters of credit ​ ​ 4,886,575 ​ ​ 4,185,261 Credit commitments ​ ​ 43,049,746 ​ ​ 32,967,149 Total exposure to credit risk outside of the statement of financial position ​ Ps. 47,936,321 ​ Ps. 37,152,410 Total maximum exposure to credit risk ​ Ps. 378,382,413 ​ Ps. 327,251,500 (**) ​ With regard to guarantees and commitments to extend the credit amounts, the maximum credit risk exposure is the amount of the commitment. Credit risk is mitigated by guarantees and collaterals as described in note 4.1.4 Mitigation of Credit Risk, Collateral and Other Credit Risk Enhancements. Each of Grupo Aval´s financial subsidiaries assume the credit risk for both the credit activity itself, which includes commercial, consumer, mortgage and microcredit credit lending and treasury activities, including interbank loans, investment portfolio management, derivatives and foreign currency trading activities, among others. Despite being independent businesses, the nature of insolvency risk of the borrower or counterparty is similar and therefore the criteria in which they are evaluated is similar. 4.1.1.A. Loan portfolio disclosure Loans are recorded at amortized cost on the statement of financial position and are classified as commercial, consumer, residential mortgage, microcredit and interbank and overnight funds.

Evaluation criteria to measure credit risk follows the principal instructions set forth by the Treasury and Credit Risk Committees. The maximum authority regarding lending is the Board of Directors for each bank, which approves the general policy and has the capacity to approve large size transactions. In the normal banking operation, authorizations for approval of loans and lines of credit depend on the amounts, credit quality, tenor and security collateral or guarantees offered by the client. The Board of Directors of each bank has delegated part of its lending authorities to different committees and executives who process the credit requests and are responsible for the analysis and credit review. Additionally, for the approval of credits, certain considerations are taken into account including but not limited to, the probability of default, the recovery percentage of guarantees received, current customer exposure, tenor and concentration by economic sector. Regarding the operations for treasury activities, the Board of Directors of the financial subsidiaries, approves the lines of credit for counterparties. Risk control is essentially carried out through three mechanisms: periodic approval of lines of credit, at least once a year evaluation of the conditions of the issuers and a report on concentrations for each client or economic group. Although each financial subsidiary is responsible for its credit decisions and risk management, Grupo Aval as a holding, through the Corporate Risk Unit oversees the implementation of appropriate risk management controls at the financial subsidiaries and has established upward loan reporting processes. The holding’s risk management staff meets on a periodically basis to discuss Grupo Aval subsidiaries’ loan portfolio, developments in industry, risks and opportunities. Grupo Aval also coordinates loan syndication among its banks to effectively leverage the combined equity of its banks and manage any risk issues. Each subsidiary of the financial sector has a Credit Risk Management System, which is managed by the credit vice-presidency or its equivalent, and includes, among others, the design, implementation and evaluation of policies and risk mechanisms defined by the Credit and Treasury Risk Committee and the Board of Directors of each entity. The operation of the Credit Risk Management System has resulted in the integration of risk measurement tools into the credit approval process in each of the financial subsidiaries. Each subsidiary of the financial sector in Colombia has two models for evaluating credit risk for the approval of commercial loans: the financial ratings model, statistical models based on financial information of the client, which are used in the approval process and for the management and review of the portfolio. The second model is based on the client´s financial ratings and its historical payment behavior with the bank, used in the process of client rating. ​ In Central America, each subsidiary has a model for evaluating credit risk for the approval of commercial loans. It is a financial ratings model, which evaluates the financial information (ratios and growth rates, among others) of each debtor, which are used in the approval process and for the management and review of the corporate and medium sized companies. This model is complemented with information on payment behavior with the bank to set a minimum rating. As a result of the COVID-19 pandemic, since the beginning of 2020 it was necessary to review and adjust origination strategies, along with approved debt limits in accordance with individual risk analysis, especially for customers identified in high-risk sectors. As economic recovery has taken place in the different regions where Grupo Aval has presence, many of the strategies implemented by the entities to mitigate the risk due to the pandemic have been reversed. For more information, see Note 1.1 Other events COVID-19 impact. 4.1.3 The Credit-risk Monitoring Process and Credit rating of the loan portfolio The monitoring process and credit risk review of each financial subsidiary is carried out in several steps including portfolio analysis by vintages, risk level rating, permanent high-risk clients’ review, restructuring processes of operations and the receipt of foreclosed assets as payment. Periodically the financial subsidiaries classify each client in one of these categories: Category A-Normal, B-Subnormal, C-Deficient, D-Doubtful recovery and E- Unrecoverable, based on the statistical models that each subsidiary has. Periodically each financial subsidiary evaluates the commercial portfolio by economic sectors, where macro-sectors are evaluated with the purpose of monitoring the concentration per economic sector and the risk level of each one. At least once in a year, each financial subsidiary carries out an individual analysis of the credit risk based on updated financial information of the client, payment record, collateral security/guarantees received, credit bureau reports and other qualitative information available; based on the information, clients are classified by risk level as mentioned above. During 2021, the analysis carried out by our financial subsidiaries required a detailed review and classification of clients by risk levels, considering the impacts of the COVID-19 pandemic effects in the Grupo Aval businesses. As of December 2021, the analysis performed by the financial subsidiaries required a detailed review and classification of customers by risk levels, considering the impact of the COVID-19 pandemic. Each risk category is explained as follows: ​ Category PD* Risk Description 1 0%- 7.5% Normal Appropriately serviced. The debtor’s financial statements or its projected cash flows, as well as all other credit information available to us, reflect adequate paying capacity 2 7.5% - 15% Acceptable above normal Adequately serviced and protected, but there are weaknesses which may potentially affect, on a transitory or permanent basis, the debtor’s paying capacity or its projected cash flows, to the extent that, if not timely corrected, would affect the collection of the credits as contracted 3 15% - 22.5% 4 22.5% - 30% Appreciable Have debtors with insufficient paying capacity or relate to projects with insufficient cash flow, which may compromise the normal collection of the obligations 5 30% - 45% Category PD* Risk Description 6 45% - 60% Significant Have the same deficiencies as loans in category 4-5, but to a larger extent; consequently, the probability of collection is highly doubtful 7 60% - 90% 8 > 90% Non-recoverability Deemed uncollectible. (*) and/or interest. ​ For mortgage loans and microcredits, the previous classification by risk levels is carried out monthly considering the number of days past due. In addition, the credit risk exposure is managed through a periodic analysis of the borrowers (or potential borrowers) to determine the repayment capacity of capital and interest. The credit risk exposure is also mitigated partly by obtaining collateral security, corporate and personal guarantees. The following table sets out information about the credit quality of financial assets measured at amortized cost. Unless specifically indicated, for financial assets, the amounts in the table represent gross carrying amounts. For loan commitments and financial guarantee contracts, the amounts in the table represent the amounts committed or guaranteed, respectively. Based on the foregoing classifications, each financial subsidiary establishes and executes collection strategies directed at maximizing the collection of the loan portfolio. As of December 31, 2021, and 2020, the following is a summary of the credit portfolio by probability of default. Explanation of the terms: Stage 1, Stage 2 and Stage 3 are included in Note 2 (2.5) (ix) and explained in detail in Note 4.1.5 (Measurement of Expected Credit Loss). ​ Total Portfolio ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ Total Exposure PD Range Stage 1 Stage 2 Stage 3 Total 0%- 7.5% ​ Ps. 180,615,328 ​ Ps. 6,434,636 ​ Ps. 384 ​ Ps. 187,050,348 7.5% -

Market Risk	4.2 Market Risk Market risk refers to the risk that a change in the level of one or more market prices, rates, indices, volatilities, correlations or other market factors, such as liquidity, will result in losses in a position or in the portfolio. Grupo Aval´s financial subsidiaries (namely Banco de Bogotá, Banco de Occidente, Banco Popular, Banco AV Villas, BAC Holding, Corficolombiana, Porvenir and the trust companies of the financial subsidiaries) actively participate in money markets, foreign exchange markets and capital markets, for both of their books (for balance sheet risk management and trading book) and to provide financial services to their customers. This is done subject to established policies and risk limits. In that regard, they hold financial asset portfolios within the allowed limits and risk levels. Market risk arises from the positions of Grupo Aval´s financial subsidiaries in debt securities investment portfolios, derivatives and equity instruments. These risks are created by changes in factors such as interest rates, inflation, foreign currency exchange rates, share prices, credit margins of instruments and their volatility, as well as the liquidity in the markets where Grupo Aval operates. Our business units and trading desks are responsible for ensuring that market risk exposures are well-managed and prudent. The risk management groups and our business unit management ensure that these risks are measured and closely monitored. A variety of limits and controls are designed to manage price and liquidity risk. Market risk is monitored through various mechanisms such as: statistically analysis (using Value-at-Risk models and related analytical measures), risk factor sensitivity analysis, and routine stress testing, conducted in collaboration with the business units by the Market Risk Unit. The material risks identified by these processes are summarized in reports produced by the Market Risk Unit that are circulated to, and discussed with, senior management. 4.2.1 Trading Book Risk Grupo Aval´s financial subsidiaries trade financial instruments for various reasons, mainly: ● To offer products tailored to specific customer needs. Some of these products are designed to hedge the financial risks of customers. ● To take advantage of arbitrage opportunities among different yield curves, assets and markets, obtaining returns with an adequate use of capital. ● To hedge asset and liability risk positions on proprietary positions, to act on behalf of customers or to take advantage of arbitrage opportunities mainly in foreign exchange and interest rates in both local and foreign markets. In carrying out these operations, Grupo Aval´s financial subsidiaries take risks, within predetermined limits. These risks are mitigated with the use of derivative products and other financial instruments within limits that are permanently monitored by risk. The following is a breakdown of Grupo Aval’s financial assets and liabilities exposed to trading risk held at December 31, 2021 and 2020. ​ ​ ​ ​ ​ ​ ​ ​ Account December 31, 2021 December 31, 2020 Financial assets ​ ​ ​ ​ ​ Debt financial assets ​ ​ ​ ​ Trading investments in debt securities ​ Ps. 4,741,287 ​ Ps. 4,780,993 Investments in debt securities mandatorily at FVTPL ​ ​ — ​ ​ 7,385 Investments in debt securities at FVOCI ​ ​ 37,493,866 ​ ​ 28,966,356 Total debt securities ​ Ps. 42,235,153 ​ Ps. 33,754,734 Derivative assets instruments ​ Ps. 1,162,909 ​ Ps. 1,133,924 Hedging derivatives assets ​ ​ 44,248 ​ ​ 156,220 ​ ​ ​ 1,207,157 ​ ​ 1,290,144 Total financial assets ​ Ps. 43,442,310 ​ Ps. 35,044,878 Liabilities ​ ​ ​ ​ Derivative liabilities instruments ​ ​ 1,049,910 ​ ​ 1,452,574 Hedging derivatives liabilities ​ ​ 55,813 ​ ​ 56,627 Total financial liabilities ​ ​ 1,105,723 ​ ​ 1,509,201 Net position ​ Ps. 42,336,587 ​ Ps. 33,535,677 ​ 4.2.2 Description of Objectives, Policies and Processes to Manage Trading Risk Our financial subsidiaries participate in money markets, foreign exchange markets and capital markets to meet their needs and those of their customers, subject to established policies and risk levels. In this respect, they manage different portfolios of financial assets within the limits and risk levels allowed. The risks assumed by Grupo Aval´s financial subsidiaries in transactions related to the trading or treasury book are consistent with the overall trading strategy, considering the market depth for each instrument, its impact on risk-weighted assets and regulatory capital, the profit budget established for each business unit, and the balance sheet structure. Trading strategies are established on the basis of approved limits, in an effort to balance the risk / return relationship. Moreover, there is a structure of limits consistent with Grupo Aval’s general philosophy and is based on capital levels, earnings performance and risk appetite. The Market Risk Management System (SARM in Spanish) allows Grupo Aval´s financial subsidiaries to identify, measure, control and monitor the market risk they are exposed to in carrying out their operations. There are several scenarios in which Grupo Aval´s financial subsidiaries are exposed to trading risks. ● Interest Rate Risk Grupo Aval’s financial subsidiaries are exposed to interest rate risk as a result of its market-making activities and proprietary trading in interest rate sensitive financial instruments (e.g., risk arising from changes in the level or implied volatility of interest rates, the timing of mortgage prepayments, the shape of the yield curve and credit spreads for credit sensitive instruments). This risk includes the risk of repricing of floating rates. Additionally, as part of the interest rate risk management, asset and liability management committees have been established to monitor the execution of these strategies. ● Foreign Exchange Risk Grupo Aval’s financial subsidiary’s portfolios are exposed to foreign exchange rate and implied volatility risk as a result of market making negotiation in foreign currencies and from maintaining foreign exchange positions. ● Equity Price Risk and Mutual Fund Risk Grupo Aval´s financial subsidiaries are exposed to equity price risk in specific investments and are exposed to mutual fund risk in short term investments in money market or mutual funds. 4.2.2.1 Risk Management Grupo Aval financial subsidiaries manage their trading positions by employing a variety of risk mitigation strategies. These strategies include diversification of risk exposures and hedging through the purchase or sale of positions in related securities and financial instruments, including a variety of derivative products (e.g., futures, forwards, swaps and options). The financial subsidiaries manage their market risk associated with its trading activities on a decentralized basis. Our corporate risk unit supervises the level of risk taken in order to ensure that its global exposure limits are observed. Senior management and the boards of directors of our banks and their financial subsidiaries play an active role in managing and controlling market risk. They do so by analyzing established reports and through committees that comprehensively monitor - both technically and fundamentally - the different variables that influence domestic and foreign markets. This process is intended to support strategic trading and portfolio decisions. Analyzing and monitoring the market risks that Grupo Aval´s financial subsidiaries take in their operations is essential for decision making and to assess potential effects on their financial position. An ongoing analysis of macroeconomic conditions is necessary in order to achieve an ideal combination of market risk, return and liquidity. The risks assumed in financial operations are reflected in a limit structure that includes different types of instruments, specific trading strategies, the market depth in which Grupo Aval´s financial subsidiaries operate, the impact on risk-weighted assets and regulatory capital, as well as the balance sheet structure. These limits are monitored daily and reported regularly to the Board of Directors of Grupo Aval´s financial subsidiaries. In order to minimize interest rate and exchange rate risks in specific positions and transactions, Grupo Aval´s financial subsidiaries manage hedging strategies by taking positions in derivative instruments such as non-deliverable forwards (NDF) related to securities, money market transactions and foreign exchange forwards. 4.2.2.2 Methods Used to Measure Trading Risk The Market Risk areas independently reviews the Company’s trading portfolios on a regular basis from a market risk perspective utilizing VaR (internal and regulatory models) and other quantitative and qualitative risk measures and analyses. Each trading business and the market risk areas also use, as appropriate, measures such as sensitivity to changes in interest rates, prices, implied volatilities and time decay to monitor and report market risk exposures. Stress testing, which measures the impact on the value of existing portfolios of specified changes in market factors for certain products, is performed periodically and is reviewed by our risk and trading areas. Reports summarizing material risk exposures are produced by the market risk areas and are provided to senior management. The Boards of Directors and the Risk Committees of Grupo Aval´s financial subsidiaries approve a framework of limits based on the value-at-risk related to the annual budget. Regulatory VaR (regulatory calculation) The Regulatory VaR calculation is primarily used for the Superintendency of Finance’s solvency ratio calculations. Each bank has standard models for capital purposes; however, they also maintain internal models in order to manage their day-to- day risk and profit decisions. The Superintendency of Finance methodology is based on the Basel II model. This model applies only to the financial subsidiaries’ investment portfolio and excludes investments not classified as trading. Total market risk is calculated on a daily basis by aggregating the VaR for each risk exposure category on a ten-day horizon, based on risk factors calculated under extreme market stress scenarios. VaR at month-end is part of the capital adequacy ratio calculation (as set forth in Decree 2555 of 2010). The Superintendency of Finance’s rules require the financial subsidiaries to calculate VaR for the following risk factors: interest rate risk, foreign exchange rate risk, equity price risk and fund risk. Correlations between risk factors are not considered. The fluctuations in the portfolio’s VaR depend on sensitivity factors determined by the Superintendency of Finance, modified duration and changes in balances outstanding. The ten-day horizon is defined as the average time in which an entity could sell a trading position in the market. The VaR calculation includes all the portfolios of the entities and their financial subsidiaries and is estimated under the methodology defined by the Superintendency of Finance of Colombia. These methods are used to determine the occurrence of potential losses among the different business units. The methods also allow comparisons of activities in different markets and identification of the riskiest positions in treasury activities. These tools are also used to determine limits on traders’ positions and to promptly review positions and trading strategies in response to changes in market conditions. VaR models have inherent limitations, partially because they rely on historical data, which may not be an indicative of future market conditions. VaR models could overestimate or underestimate the value at risk if market conditions vary significantly and they do not calculate the greatest possible loss. That’s why each company uses additional measurement tools in order to compensate for the VaR limitations. Expected Shortfall analysis, stress test and back tests are part of the risk measurement tools in the financial subsidiaries. The methods used to measure VaR are assessed regularly and backtested to check their efficiency. Grupo Aval´s financial subsidiaries have tools to carry out portfolio stress and/or sensitivity tests, using extreme scenario simulations. Additionally, there are limits according to the "risk type" associated with each of the instruments comprising the different portfolios. These limits are related to sensitivity or impact on the value of the portfolio as a result of fluctuations of specific risk factors such as: interest rate (Rho), exchange rate (Delta) and volatility (Vega). Grupo Aval´s financial subsidiaries have counterparty and trading limits for each trader in the trading platforms for the markets where they operate. trading limits are controlled daily by the back and middle offices of each entity. Trading limits for individual traders are assigned based upon the individual´s level in the organization, market and trading experience and product and portfolio management knowledge. There is also a process to monitor the prices of fixed-income securities traded in foreign markets published by investment price providers for those jurisdictions. In addition, fixed income securities are subject to a qualitative liquidity analysis to determine the market depth for those instruments. Finally, the daily transaction monitoring process includes controlling different aspects of trading, such as terms of negotiation, non-conventional or off-market transactions, and related party transactions. BAC Holding and MFH´s Value at Risk are consolidated through Banco de Bogotá using the standard methodology established by the Colombian Superintendency of Finance. According to the standard model, the market value-at-risk (VaR) for Grupo Aval´s financial subsidiaries consolidated at their level of December 31, 2021 and 2020 was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ December 31, 2020 ​ ​ Basis points of ​ Basis points of Entity ​ Value ​ regulatory capital ​ Value ​ regulatory capital Banco Bogotá 1,013,946 100 942,885 ​ 84 Banco de Occidente 327,612 135 223,942 65 Banco Popular 173,261 169 101,773 52 Banco AV Villas 126,799 2 110,085 1 Corficolombiana 211,684 7 178,478 5 Porvenir 23,700 168 13,897 ​ 183 ​ The following tables show the VaR calculation relating to each of the risk factors described above and based on the Superintendency of Finance Methodology (Regulatory VaR) for the years ended December 31, 2021 and 2020, for a ten-day horizon for each of our Colombian banking subsidiaries.

As Corficolombiana does not have a relevant number of loans or other significant risk weighted assets, the ratio of the market risk weighted assets to total risk weighted assets is higher than in the banks. As a pension fund, Porvenir has a value-at-risk measurement methodology that differs from credit establishments and is established by the Superintendency of Finance.

In addition, it does not discriminate between listed and unlisted equity investments or between those which consolidate and those which do not. It includes investments in non-financial institutions. Holding periods for many of Corficolombiana’s equity investments exceed ten years. Its largest investments have remained in the portfolio for several years and are intended to remain as permanent investments. Therefore, no value at risk is estimated. At December 31, 2021 and 2020, the only investments subject to regulatory VaR were holdings in Mineros S.A. The following table breaks down our investments subject to regulatory VaR by time since initial investments at December 31, 2021 and 2020. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ At December 31, ​ ​ 2021 ​ 2020 ​ Investment ​ ​ Investment ​ ​ ​ ​ subject to ​ ​ ​ Percentage ​ subject to ​ ​ ​ ​ ​ ​ Regulatory ​ Regulatory ​ of ​ Regulatory ​ Regulatory ​ Percentage of ​ ​ VaR ​ VaR ​ portfolio ​ VaR ​ VaR ​ portfolio More than 36 months 85,229 ​ 12,529 ​ 100 % 85,832 ​ 12,617 ​ 100 % Total 85,229 12,529 100 % 85,832 12,617 100 % ​ ​ ​ 4.2.3 Structural foreign exchange risk Grupo Aval´s financial subsidiaries have agencies and subsidiaries offshore and have assets and liabilities in foreign currencies and are thus exposed to changes in the exchange rates, primarily the United States Dollar. Foreign exchange risk is present when there are assets and liabilities denominated in foreign currency, when investments are made in foreign subsidiaries and branches and when we extend loans or take funds in foreign currency. There is also foreign exchange risk in foreign currency off balance sheet transactions. Subsidiaries of the financial sector in Colombia are authorized by the country’s central bank (Banco de la República) to trade currencies and to maintain balances in foreign currency in accounts abroad. Colombian law allows for banks to maintain a net daily asset or liability position in foreign currency, determined as the difference in foreign currency denominated rights and foreign currency denominated obligations including both on and off-balance sheet positions. On a separate basis, the average of this difference over three business days cannot exceed twenty percent (20%) of the entity’s regulatory capital. On a consolidated basis, the average of this difference over three business days (positive or negative) cannot exceed forty percent (40%) of the consolidated entity´s regulatory capital. The maximum and minimum total foreign currency position and the spot foreign currency position are determined according to each entity´s regulatory capital. The regulatory capital that is used in the calculations, corresponds to the regulatory capital of the last business day of the previous two-months. The exchange rate used in the calculation is the average of the exchange rate of the previous month set by the Superintendency of Finance. A substantial amount of Grupo Aval’s foreign currency assets and liabilities are in U.S. dollars. Details on the assets and liabilities in foreign currency held by Grupo Aval at December 31, 2021 and 2020 are shown below: ​ ​ ​ ​ ​ ​ ​ ​ December 31,2021 ​ ​ Other currencies ​ Total in ​ ​ U.S. dollars ​ converted to U.S. ​ Colombian pesos Account (Millions) dollars (Millions) (Millions) Financial assets ​ ​ ​ Cash and cash equivalents ​ 4,711 ​ 2,021 ​ 26,800,791 Trading investments in debt securities ​ 111 ​ 13 ​ 493,454 Investments in debt securities at FVOCI ​ 4,459 ​ 1,083 ​ 22,062,791 Investments in debt securities at amortized cost ​ 118 ​ - ​ 469,723 Loan portfolio financial assets at amortized cost ​ 20,187 ​ 5,804 ​ 103,475,257 Derivative financial assets held for trading ​ 239 ​ - ​ 952,889 Derivative financial assets held for hedging ​ 4 ​ - ​ 16,669 Trade receivable ​ 383 ​ 229 ​ 2,435,666 Total financial assets ​ 30,212 ​ 9,150 ​ 156,707,240 ​ ​ ​ ​ ​ ​ ​ ​ ​ Other currencies Total in ​ ​ U.S. dollars ​ converted to U.S. ​ Colombian pesos Account ​ (Millions) ​ dollars (Millions) ​ (Millions) Financial liabilities ​ ​ ​ Derivative financial liabilities held for trading ​ 204 ​ - ​ 811,062 Derivative financial liabilities held for hedging ​ 8 ​ - ​ 33,160 Customer deposits ​ 20,630 ​ 7,394 ​ 111,566,151 Financial obligations ​ 10,562 ​ 833 ​ 45,363,639 Accounts payable ​ 536 ​ - ​ 2,134,728 Total financial liabilities ​ 31,940 ​ 8,227 ​ 159,908,740 Net financial asset (liability) position ​ (1,728) ​ 923 ​ (3,201,500) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2 ​ ​ ​ ​ ​ ​ December 31,2020 ​ ​ Other currencies ​ Total in ​ ​ U.S. dollars ​ converted to U.S. ​ Colombian pesos Account (Millions) dollars (Millions) (Millions) Financial assets ​ ​ ​ Cash and cash equivalents ​ 5,521 ​ 2,043 ​ 25,963,067 Trading investments in debt securities ​ 122 ​ — ​ 417,925 Investments in debt securities at FVOCI ​ 4,092 ​ 860 ​ 16,997,663 Investments in debt securities at amortized cost ​ 150 ​ 4 ​ 527,510 Loan portfolio financial assets at amortized cost ​ 19,678 ​ 4,754 ​ 83,863,582 Derivative financial assets held for trading ​ 258 ​ 1 ​ 887,957 Derivative financial assets held for hedging ​ 36 ​ 10 ​ 156,220 Trade receivable ​ 367 ​ 201 ​ 1,949,445 Total financial assets ​ 30,224 ​ 7,873 ​ 130,763,369 ​ ​ ​ ​ ​ ​ ​ ​ ​ Other currencies Total in ​ U.S. dollars converted to U.S. Colombian pesos Account ​ (Millions) dollars (Millions) (Millions) Financial liabilities Derivative financial liabilities held for trading ​ 349 ​ — ​ 1,197,924 Derivative financial liabilities held for hedging ​ 8 ​ — ​ 26,924 Customer deposits ​ 21,144 ​ 6,916 ​ 96,314,534 Financial obligations ​ 9,717 ​ 712 ​ 35,797,463 Accounts payable ​ 475 ​ — ​ 1,630,860 Total financial liabilities 31,693 7,628 134,967,705 Net financial asset (liability) position (1,469) 245 (4,204,336) ​ ​ Grupo Aval’s financial subsidiaries hedge their foreign exchange exposure using derivatives instruments, especially forwards. The net foreign currency position of each subsidiary is monitored on a daily basis. Grupo Aval has a number of investments in foreign subsidiaries and branches whose net assets are exposed to foreign exchange risk because of the translation of gains or losses for the purpose of consolidating their financial statements. The exposure arising from net assets in foreign operations is hedged primarily with financial obligations, bonds and foreign exchange derivative instruments. The following table presents sensitivities of profit or loss before taxes and equity (OCI) to reasonably possible changes in exchange rates applied at the end of the reporting period relative to the functional currency of the respective Group entities, with all other variables held constant: ​ ​ ​ ​ ​ ​ ​ ​ December 31,2021 Increase Decrease ​ ​ Ps.100 per U.S. ​ Ps.100 per U.S. ​ ​ dollar ​ dollar Equity Ps. 175,470 Ps.

The sensitivity in profit or loss was calculated for monetary assets and liabilities denominated in currencies other than the functional currency of the respective entities of the Group, including intercompany balances which are not hedged. The Group’s exposure to currency risk at the end of the reporting period is not representative of the typical exposure during the year. ​ 4.2.4 Structural Interest Rate Risk Non-trading instruments consist primarily of loans and deposits. The net interest margin of our financial subsidiaries may be affected by changes in interest rates. Losses can result from unexpected movements in interest rates. For this reason, our financial subsidiaries monitor the interest rate risk daily and set limits on asset and liability mismatches. Grupo Aval´s financial subsidiaries monitor their interest rate risk daily and set limits to repricing mismatches between assets and liabilities. They analyze their interest rate exposure in a dynamic way. Scenario modelling considers renewal of existing positions, financing alternatives, and hedges. Considering these scenarios, the financial subsidiaries calculate the profit and loss impact of changes in interest rates. The following table shows interest rates exposure for assets and liabilities at December 31, 2021 and 2020. In this table, fixed rate instruments are classified according to their maturity date and floating rate instruments are classified according to their repricing date. The following analysis includes the interest rate exposure of non-interest-bearing and interest-bearing assets and liabilities by maturity bucket for our financial subsidiaries: ​ ​ ​ December 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Less than From one to From six to More than a Non- ​ ​ Assets ​ one month ​ six months ​ twelve months ​ year ​ interest ​ Total Cash and cash equivalents ​ Ps. 5,283,158 ​ Ps. — ​ Ps. — ​ Ps. — ​ Ps. 31,359,671 ​ Ps. 36,642,829 Trading investments in debt securities ​ ​ 32,533 ​ ​ 795,986 ​ ​ 716,615 ​ ​ 3,196,153 ​ ​ — ​ ​ 4,741,287 Investments in debt securities mandatorily at FVTPL ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — Investments in debt securities at FVOCI ​ ​ 691,305 ​ ​ 4,549,642 ​ ​ 1,960,040 ​ ​ 30,292,879 ​ ​ — ​ ​ 37,493,866 Investments in debt securities at amortized cost ​ ​ 1,503,177 ​ ​ 3,710,000 ​ ​ 385,985 ​ ​ 175,908 ​ ​ — ​ ​ 5,775,070 Service concession arrangements ​ ​ — ​ ​ — ​ ​ — ​ ​ 3,228,480 ​ ​ — ​ ​ 3,228,480 Commercial loans ​ ​ 38,417,251 ​ ​ 31,409,143 ​ ​ 10,996,375 ​ ​ 41,205,035 ​ ​ — ​ ​ 122,027,804 Consumer loans ​ ​ 17,866,168 ​ ​ 11,445,530 ​ ​ 2,254,215 ​ ​ 45,323,232 ​ ​ — ​ ​ 76,889,145 Mortgages loans ​ ​ 14,247,634 ​ ​ 833,794 ​ ​ 416,847 ​ ​ 13,622,041 ​ ​ — ​ ​ 29,120,316 Microcredit loans ​ ​ 42,175 ​ ​ 13,241 ​ ​ 36,456 ​ ​ 225,867 ​ ​ — ​ ​ 317,739 Interbank and overnight funds ​ ​ 3,121,735 ​ ​ 96,698 ​ ​ — ​ ​ — ​ ​ — ​ ​ 3,218,433 Trade receivable ​ ​ — ​ ​ 163 ​ ​ — ​ ​ 455,859 ​ ​ 15,725,505 ​ ​ 16,181,527 Total Assets ​ Ps. 81,205,136 ​ Ps. 52,854,197 ​ Ps. 16,766,533 ​ Ps. 137,725,454 ​ Ps. 47,085,176 ​ Ps. 335,636,496 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Less than From one to From six to More than a Non- Liabilities ​ one month ​ six months ​ twelve months ​ year ​ interest ​ Total Checking accounts ​ Ps. 34,024,691 ​ Ps. — ​ Ps. — ​ Ps. — ​ Ps. 25,201,158 ​ Ps. 59,225,849 Time deposits ​ ​ 6,947,437 ​ ​ 36,252,017 ​ ​ 18,492,124 ​ ​ 23,838,666 ​ ​ — ​ ​ 85,530,244 Saving deposits ​ ​ 89,097,128 ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 89,097,128 Other deposits ​ ​ 9,727 ​ ​ 92,610 ​ ​ — ​ ​ — ​ ​ 514,864 ​ ​ 617,201 Interbank and overnight funds ​ ​ 8,935,468 ​ ​ 1,169,368 ​ ​ 501,221 ​ ​ 66,358 ​ ​ — ​ ​ 10,672,415 Leases contracts ​ ​ 50,860 ​ ​ 244,198 ​ ​ 173,335 ​ ​ 2,413,764 ​ ​ — ​ ​ 2,882,157 Borrowing from banks and similar ​ ​ 3,323,809 ​ ​ 11,132,293 ​ ​ 3,823,854 ​ ​ 5,962,597 ​ ​ — ​ ​ 24,242,553 Long-term debt ​ ​ 296,675 ​ ​ 3,923,750 ​ ​ 5,940,106 ​ ​ 22,097,401 ​ ​ — ​ ​ 32,257,932 Borrowing from development entities ​ ​ 1,188,693 ​ ​ 955,697 ​ ​ 37,388 ​ ​ 1,045,491 ​ ​ — ​ ​ 3,227,269 Total Liabilities ​ Ps. 143,874,488 ​ Ps. 53,769,933 ​ Ps. 28,968,028 ​ Ps. 55,424,277 ​ Ps. 25,716,022 ​ Ps. 307,752,748 ​ December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Less than ​ From one to ​ From six to ​ More than a ​ Non- ​ Assets ​ one month ​ six months ​ twelve months ​ year ​ interest ​ Total Cash and cash equivalents ​ Ps. 5,103,991 ​ Ps. — ​ Ps. — ​ Ps. — ​ Ps. 28,921,544 ​ Ps. 34,025,535 Trading investments in debt securities ​ ​ 63,016 ​ ​ 1,315,010 ​ ​ 351,964 ​ ​ 3,051,003 ​ ​ — ​ ​ 4,780,993 Investments in debt securities mandatorily at FVTPL ​ ​ — ​ ​ — ​ ​ — ​ ​ 7,385 ​ ​ — ​ ​ 7,385 Investments in debt securities at FVOCI ​ ​ 947,691 ​ ​ 3,558,616 ​ ​ 2,367,715 ​ ​ 22,092,334 ​ ​ — ​ ​ 28,966,356 Investments in debt securities at amortized cost ​ ​ 2,206,728 ​ ​ 2,856,442 ​ ​ 302,641 ​ ​ 214,317 ​ ​ — ​ ​ 5,580,128 Service concession arrangements ​ ​ — ​ ​ — ​ ​ — ​ ​ 2,958,385 ​ ​ — ​ ​ 2,958,385 Commercial loans ​ ​ 28,249,224 ​ ​ 44,158,080 ​ ​ 8,350,536 ​ ​ 30,229,098 ​ ​ — ​ ​ 110,986,938 Consumer loans ​ ​ 13,451,176 ​ ​ 10,002,297 ​ ​ 1,947,260 ​ ​ 40,434,724 ​ ​ — ​ ​ 65,835,457 Mortgages loans ​ ​ 12,541,450 ​ ​ 640,162 ​ ​ 49,522 ​ ​ 11,327,637 ​ ​ — ​ ​ 24,558,771 Microcredit loans ​ ​ 42,825 ​ ​ 16,3
Liquidity Risk	4.3 Liquidity Risk Liquidity risk management has always been a basic element of Grupo Aval’s business strategy and a fundamental cornerstone, together with capital, on which the strength of its balance sheet rests. Liquidity risk is related to the inability of Grupo Aval´s subsidiaries to fulfill their obligations with customers, financial market counterparties, lenders, suppliers, authorities or other stakeholders at any given moment, in any currency and in any location. Structural liquidity management aims to finance the recurring nature of a company’s activities under optimal terms of time and cost, avoiding taking unwanted liquidity risks. At Grupo Aval, the financing and liquidity model is decentralized and based on autonomous subsidiaries that are responsible for covering their own liquidity needs. Therefore, each entity reviews its available resources on a daily basis in order to control its liquidity risk. The financial subsidiaries of Grupo Aval are responsible for complying with the regulatory liquidity requirements, as well as meeting the obligations arising from their current and future activity. In consequence, they will either take deposits from their customers, or by resorting to the wholesale markets where they operate. Grupo Aval’s financial subsidiaries have a strong capacity as well as to raise funds in the wholesale markets. Financial subsidiaries comply with the requirements for liquidity risk management of the jurisdictions in which they operate. They define policies that govern the functions of identification, measurement, control and monitoring required to manage daily liquidity requirements, comply with minimum liquidity buffers and establish liquidity contingency plans to deal with any unexpected situation. The methodology for the assessment and measurement of liquidity risk at BAC Holding and subsidiaries include: a) Generation of liquidity GAP analysis by currency for the short and long term, including normal and stressed scenarios; b) Coverage ratios, by currency, on 1 day and 30 days horizons, under normal and stressed scenarios; c) Prudential regulation of maturity ratios, by currency, for 1 and 3 months horizons; d) Indicator of liquidity coverage by currency according to regulation; e) Internal measurements to assess liquidity risk, by currency (global liquidity indicator). Financial subsidiaries controlled by Grupo Aval, in Colombia, are required to maintain adequate liquidity positions based on the Superintendency of Finance’s liquidity parameters, using a short-term liquidity index (Indicador de Riesgo de Liquidez), or “IRL,” that measures liquidity for different time horizons from 1 to 90 days. This index is defined as the difference between adjusted liquid assets and net liquidity requirements. • Liquid assets include total debt securities adjusted by market liquidity and exchange rate, excluding investment securities at amortized cost different from mandatory investments, Central Bank deposits and available cash. • Net liquidity requirements are the difference between expected contractual asset and contractual and non-contractual liability cash flows. Cash flows from past due loans are not included in this calculation. During 2020, as part of its convergence towards Basel III standards, the Superintendency of Finance incorporates the segmentation by type of deposits in the calculation of non-contractual liability cash flows. The methodology segments saving deposits in eight categories, according with their balance and the type of customer, then calculates the run-off rate for each category and finally multiplies both to determine the non-contractual reserve. Grupo Aval´s financial subsidiaries assess the volatility of deposits, debt levels, the asset and liability structure, the liquidity of different asset types, the availability of lines of credit and the effectiveness of asset and liability management. The objective is to have adequate liquidity to manage possible stress scenarios. The quantification of appropriate money market funding levels is an integral part of the liquidity measurement carried out by each entity. Based on statistical analysis, primary and secondary sources of liquidity are identified in order to ensure funding stability and diversification, and to minimize concentration. Financial subsidiaries in Colombia and other countries must maintain cash on hand and in Central Banks deposits in order to comply with reserve requirements. The reserve requirement calculations are based on the daily average of the different types of deposits on a biweekly basis. As of December 31, 2021, and 2020, all of Grupo Aval´s financial subsidiaries comply with reserve requirements. Details on the required percentage in each country are shown below: ​ ​ ​ ​ ​ ​ Requested Percentage Country Details % Colombia Checking account and Savings accounts ​ 8% ​ Time deposits > 18 months ​ 3.5% Guatemala Deposits and Capital raising ​ 14.6% El Salvador Demand deposits ​ 17.4% ​ Saving Deposits ​ 15.4% ​ Debt securities ​ 5% ​ ​ Debt overseas Banks ​ 3% ​ ​ Time Deposits ​ 12% Honduras Demand deposits in local currency ​ 12% ​ Demand deposits in foreign currency ​ 24% Nicaragua Daily, Liabilities in local and foreign currency ​ 10% ​ Biweekly, Liabilities in local and foreign currency ​ 15% Costa Rica Demand deposits in local currency ​ 12% ​ Demand deposits in foreign currency ​ 15% ​ There are no reserve requirements for our subsidiaries located in Panamá because there is no Central Bank to regulate such requirements.

Fixed income investments at amortized cost and financial investments pledged as collateral or subject to any other type of encumbrance, preventive measure or of any nature, that prevent their free assignment or transfer, as well as those that have been transferred under repurchase agreements, simultaneous or temporary transfer of securities are excluded. The value of the liquid assets mentioned above is calculated at the market price of the fair value on the date of the evaluation. (2) This amount is the remaining value of the liquid assets in the specified time period, or the IRL, that is calculated as the difference between liquid assets and liquid assets requirement, according to the IRL methodology, the liquidity requirement is the difference of contractual cash inflows and contractual and non-contractual cash outflows during a given period. The liquidity calculations described above assume normal liquidity conditions, according to the contractual flows and historical experience of each of the financial subsidiaries. for extreme liquidity events caused by unusual deposit withdrawals, the financial subsidiaries have contingency plans that include available credit lines with other financial institutions and access to special lines of credit with Colombia´s Central Bank, in accordance with current regulations. These lines of credit are granted when required, and are collateralized by Colombian government securities or by a portfolio of high-quality loans, as specified in the Central Bank regulations. Grupo Aval´s financial subsidiaries did not access the Central Bank special lines of credit during the years ended at December 31, 2021 and 2020. The banks in each country are responsible for their liquidity position on a stand-alone basis. They have access to funding mechanisms with their central banks, and to funding through credit lines. Short-term credits are offered by correspondent banks and financing is granted by multilateral organizations, among others.

Regulatory capital management	​ 4.4 Regulatory capital management Grupo Aval, Financial Holding As a result of Colombian Law 1870 of 2017 (also known as Financial Conglomerates Law), that came in effect on February 6, 2019, Grupo Aval is now also subject to the inspection and supervision of the Superintendency of Finance (SFC, for its acronym in Spanish). This law created the legal category of financial holding companies and of financial conglomerates and gives the Colombian Finance minister the power, to impose capital adequacy requirements on the financial conglomerates on an aggregate/consolidated basis, among others. In compliance with Decree 774 issued on May 8th, 2018 by the Colombian Government that came in effect on 8th of November 2019 after an 18-month transition period and the External Circular 012 of June 5, 2018 (in Spanish Circular Externa 012 del 5 de junio de 2018 ​ Grupo Aval’s financial subsidiaries Decree 2555 of 2010 (as modified by Decree 1771 of 2012, Decree 1648 of 2014, Decree 2392 of 2015, Decrees 1477 of 2018 and 1421 of 2019) sets forth capital adequacy requirements for Colombian credit institutions. Between August 1, 2013 and January 1, 2021, technical capital for Colombian credit institutions consisted of the sum of total basic capital (patrimonio básico) or total primary capital (Tier I), and secondary capital (patrimonio adicional) or secondary capital (Tier II). Primary capital (Tier I) consist of the sum of ordinary basic capital or primary capital (patrimonio básico ordinario) and additional basic capital or additional primary capital (patrimonio básico adicional). Tier I and Tier II, as defined herein, may differ to the manner in which those terms are used in other jurisdictions. The total solvency ratio prior to January 1, 2021 was defined as the value of the technical capital calculated in the terms of the Decree 2555 of 2010, divided by risk-weighted assets by level of credit and market risk. Credit institutions’ technical capital had to be at least 9.0% of the institution’s total risk-weighted assets and also had comply with a measure of “core solvency” for Tier I, which required higher-quality capital set at a minimum of 4.5% of total risk-weighted assets. Pursuant to Decree 2555 of 2010 (as amended), the Superintendency of Finance must grant prior approval of the eligibility of a debt, equity or hybrid instrument in order to be classified as Tier I, Additional Tier I (AT1) or Tier II. The Decrees 1477 of 2018 and 1421 of 2019 introduced Basel III principles to estimate adequate capital in credit establishments. The main changes contained in these Decrees, which came into effect on January 1, 2021, are as follows: ● Total solvency ratio is defined as the value of the technical capital (CET1, AT1 and T2) calculated under the terms of the Decree 1477 of 2018 and the Decree 1421 of 2019, divided by risk-weighted assets by level of credit, market and operational risk, at a minimum of 9% ; ● A minimum Core Equity Tier 1 (CET1) of 4.5% ; ● A minimum Core Equity Tier 1 plus Additional Tier 1 (AT1) of 6% ; ● A capital conservation buffer of 1.5% consisting of CET1; ● A systemic risk buffer of 1.0% for systemically important financial institutions (SIFIS) consisting of CET1; and ● Includes an operational risk component in risk weighted assets; ● In addition, these Decrees established a minimum leverage ratio of 3% . These indicators (with the exception of the leverage ratio) must be achieved gradually from 2021 to 2024, in accordance with the transition plan established in the regulation. Banco de Bogotá was considered an Entity of Systemic Importance, according to Circular Externa 76 of December 2, 2020, issued by the Superintendency of Finance and therefore must comply with this systemic buffer. The following chart presents the statutory transition period as set forth in the Decrees 1477 of 2018 and 1421 of 2019: ​ ​ (1) Requires highest quality of capital. (2) Will only apply to SIFIs as defined by the Superintendency of Finance. In accordance with the minimum capital requirements and in compliance with the Superintendency of Finance of Colombia’s new regulation, Grupo Aval and its financial subsidiaries are aimed to accomplish the guidelines of Decree 1421 which was issued on August 6, 2019, which introduced minimum capital requirements for operational risk to credit establishments adopting the Basel III standard. The decree includes a transition period of 18 months, due on January 1, 2021.

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

Value on a Non-Recurring Basis Grupo Aval is required on a nonrecurring basis to adjust the carrying value of certain assets and liabilities or provide valuation allowances. 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, 2021 and 2020 at fair value less cost of sale: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ Total December 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired collateralized loans Ps. — Ps. — Ps. 1,959,513 Ps. 1,959,513 Non- current assets held for sale ​ ​ — ​ ​ — ​ ​ 208,426 ​ ​ 208,426 ​ Ps. — Ps. — Ps. 2,167,939 Ps. 2,167,939 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ Total December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired collateralized loans Ps. — Ps. — Ps. 1,508,693 Ps. 1,508,693 Non- current assets held for sale ​ ​ — ​ ​ — ​ ​ 240,412 ​ ​ 240,412 ​ Ps. — Ps. — Ps. 1,749,105 Ps. 1,749,105 ​ ​ ​ 5.3 Fair Value determination The following tables provide information about valuation techniques and significant inputs when measuring fair value on a recurring basis for assets and liabilities, with fair value hierarchy classification of level 2 or level 3.

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 8.39% and 8.80% each year. ​ (*) Nominal WACC calculated under the Capital Asset Pricing Model (CAPM) methodology for each, updated annually. The following variables were used for determining the WACC: ● Beta unlevered USA (Oil/Gas Distribution): Damodaran. (Unlevered Beta 0.59, 2020) ● Risk Free Rate, Source: Geometric Average 1996-2020 of American bonds “T-Bonds”. ● Market Return, Source: Geometric Average 1996-2020 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”).

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 2022-2024 cash flows was forecasted based on the average of the last 3 years of the Technically Specified Rubber (TSR20) per ton since January 2019 Ps. 0.41 (US$ 1,530/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 2022-2023 cash flows was forecasted based on the average price of palm oil since January 2020 (US$ 810.8/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 15.4) ​ 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 and level 2 of the fair value hierarchy The following table summarizes the transfer between fair value levels 1 and 2 during 2021 and 2020. In general, transfers between Level 1 and Level 2 in the investment portfolios are due, fundamentally, to changes in the liquidity levels of the securities in the markets.

Disclosure of detailed information about hedges [abstract]
HEDGE ACCOUNTING	NOTE 10 – HEDGE ACCOUNTING In accordance with its risk management policies, Grupo Aval uses hedge accounting to manage foreign exchange risk relating to investments in foreign operations and in forecasted transactions of its subsidiary Promigas, as follows: Hedges of net investment in foreign operations Banco de Bogotá, Banco de Occidente and Promigas are exposed to foreign exchange risk related to their investments in foreign subsidiaries, that have the US Dollar as functional currency. The purpose of hedge accounting is to mitigate and offset any adverse changes resulting from the fluctuation in exchange rate of the Colombian Peso and the functional currency of such investments. The impacts of those movements are reflected in the cumulative translation adjustment in other comprehensive income of the consolidated financial statements. To cover this risk, Grupo Aval hedges its exposure through foreign currency financial liabilities expressed in U.S. dollars and forward contracts for the sale of U.S. dollars. Changes in the Colombian peso against the U.S. dollar have been as follows: ​ ​ ​ ​ ​ ​ Date Value of US$ 1 Variation in pesos December 31, 2019 3,277.14 27.39 December 31, 2020 3,432.50 155.36 December 31, 2021 3,981.16 548.66 ​ According to the information described above, the following table shows movements of OCI gross of taxes, related to hedges of net investment in foreign operations: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Exchange Exchange ​ ​ ​ ​ Translation ​ difference of ​ difference ​ ​ ​ ​ ​ adjustment of ​ financial ​ in forward ​ Net OCI Detail of investment the investments liabilities contracts account BAC Holding and MFH (1) Ps. 2,338,582 Ps.

(653,995) (1) Includes only a portion of this investments hedged (2) Includes Banco de Bogotá Panamá, Banco Bogotá Finance, Ficentro, Nassau and contributions of foreign branches in Miami and New York. (3) ​ Hedging with Forward Contracts Forward contracts to sell U.S. dollars have been contracted to hedge part of the net foreign investment that Banco de Bogotá has in Leasing Bogotá Panamá and other foreign subsidiaries. The forward contracts were executed with counterparties from the financial sector and the hedge was documented as a "dynamic hedging strategy", where new forward contracts are signed simultaneously as the previous ones expire. According to IAS 39, changes in the fair value of derivatives exclusively due to exchange rate changes in the peso against the U.S. dollar are registered under “Other Comprehensive Income” in equity. The ineffective part of the hedge is recognized in the statement of income for the period. Hedging with Debt in Foreign Currency in U.S. dollars Debt financial instruments that are not derivatives can be designated as hedging instruments for changes in foreign currency exchange rates. According to this rule, Banco de Bogotá and Banco de Occidente designed debt denominated in U.S. dollar as hedging instruments of their foreign subsidiaries as follows: ● Bonds issued by Banco de Bogotá in the international market were designated as hedging instruments of its investment in BAC Holding and MFH amounting US $1,486 million in 2021 and US $2,067 million in 2020. ● Other financial liabilities in the amount of US $275 million as December 31, 2021 (US $245 million as of December 31, 2020) were used to hedge part of the net foreign investment that Banco de Occidente and Promigas have in foreign subsidiaries as part of a hedging strategy, by which new obligations are continuously designated as hedging instruments to replace the previous ones as they expire over time. ● Between December 21, 2015 and November 2, 2016, financial liabilities designated as hedging instruments described above included an intra-group liability amounting to US $500 million that Banco de Bogotá had as a hedging instrument of its investment in BAC Holding. This operation was eliminated in the consolidation process of Grupo Aval and was excluded from the foreign investment hedge accounting. Starting on May 1st and up to November 2nd, 2016 Grupo Aval designated financial assets in foreign debt securities amounting to US $500 million as cash flow hedge, the foreign exchange differences of this intra-group liability were not eliminated in the consolidation process and recorded in Other Comprehensive Income in the amount of Ps. 73,708 . This amount could be realized in the future as income when the investment in Leasing Bogotá Panamá is sold. On November 2nd, 2016 Banco de Bogotá cancelled the intragroup liability amounting to US $500 million which was replaced in the foreign investment hedge accounting with other obligations in foreign currency with third parties. Hedging of Future Transactions In the ordinary course of its operations Promigas S.A. and its subsidiaries receive income in U.S. Dollars derived from the transportation of gas. Promigas and its subsidiaries hedge the exchange risk arising in future transactions of highly probable gas transportation income, entering into forward contracts for the sale of U.S. dollars with financial entities different from the ones consolidated into Grupo Aval. The following is the summary of Promigas and its subsidiaries open cash flow hedges: ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 December 31, 2020 ​ Income in Thousands of US$ dollars forecasted 115,124 ​ 187,128 Notional amount contracts forward Thousands of US$ 115,104 ​ 187,128 % hedged 90 % 100 % Fair value in Colombian pesos 7,943 ​ (4,345) ​ # of contracts 73 ​ 144 ​ ​ ​ Hedging of exchange rate risk As of December 31, 2020, MFH uses interest rate swaps and cross currency swaps (“Cross Currency Swaps”) to reduce the exchange rate risk of financial liabilities. Such contracts are recorded at fair value in the consolidated statement of financial position, in other assets and other liabilities, as appropriate. As of December 31, 2021, this hedge was no longer in effect. ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 December 31, 2020 ​ Income in Thousands of US$ dollars forecasted ​ — ​ 113,257 ​ Notional amount contracts swap Thousands of US$ ​ — ​ 100,000 ​ % hedged ​ — % 88 % Fair value in Colombian pesos ​ — ​ 17,979 ​ # of contracts ​ — ​ 1 ​ ​ ​ Concesionaria Vial del Oriente S.A.S during the year ended December 31, 2021 hedged the foreign exchange risk of the interest flows of the debt in dollars with Grupo Aval Limited, the debt is eliminated in the Grupo Aval consolidated, but the foreign exchange is not eliminated. ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 December 31, 2020 ​ Income in Thousands of US$ dollars forecasted ​ 39,244 ​ — ​ Notional amount contracts swap Thousands of US$ ​ 39,244 ​ — ​ % hedged ​ 100 % — % Fair value in Colombian pesos ​ 9,992 ​ — ​ # of contracts ​ 1 ​ — ​ ​ During the years ended December 31, 2021, 2020 and 2019, an exchange difference recognized under “Other Comprehensive Income” as a result of cash flow hedge accounting of income (loss) from these highly probable transactions, was reclassified to profit or loss in the amounts of Ps. 16,859, Ps. 34,183 and Ps. 20,066 respectively. ​ The movement of the accumulated OCI account related to cash flow hedges in Colombian pesos during the years ended on December 31, 2021, 2020 and 2019 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 December 31, 2020 December 31, 2019 Balance at the beginning of the year ​ Ps.

The hedging is considered as such if the effectiveness of the hedging is in a range between 80% and 125%. Such effectiveness is assessed by Grupo Aval’s entities at least quarterly and at the end of each accounting period. Grupo Aval has documented the hedging effectiveness of its foreign currency denominated investments based on the portion of the net investment hedged at the beginning of the hedging relationship. Since the net balance of these investments fluctuates during the year, Grupo Aval evaluates the hedging relationship on a daily basis as well as the result of the testing of hedge effectiveness. Hedge Effectiveness with Forward Contracts Grupo Aval applies the method of the forward rate used in forward contracts to evaluate the hedge effectiveness; for such purpose, Grupo Aval measures the hedge ineffectiveness comparing the value of current forward contracts, which serve as hedge, with the change in the value of a hypothetical derivative with the same maturity. Hedge Effectiveness with Debt Instruments in Foreign Currency For debt instruments in foreign currency designated as a hedging instruments, the gain or loss arising from the conversion of the debt to Colombian Pesos is based on the current exchange rate between the U.S. dollar and the Colombian Peso, which is the functional currency of Grupo Aval. If the notional amount of the hedging instrument exactly matches with the portion of the hedged investment in foreign operations, no ineffectiveness is registered in the statement of income. Derivative Financial Instruments for hedging purposes comprise the following: ​ According to information described above, the following table contains the fair value of derivative financial instruments used for hedging: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ December 31, 2020 Item Assets Liabilities Assets Liabilities Forward contracts ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency to buy Ps. 5,562 Ps. 624 Ps. 951 Ps. 26,473 Foreign currency to sale ​ ​ 1,115 ​ ​ 32,536 ​ ​ 122,374 ​ ​ 451 Subtotal Ps. 6,677 Ps. 33,160 Ps. 123,325 Ps. 26,924 Swap ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cross currency ​ ​ 9,992 ​ ​ — ​ ​ 32,895 ​ ​ — Interest rate ​ ​ 27,579 ​ ​ 22,653 ​ ​ — ​ ​ 29,703 Subtotal ​ Ps. 37,571 Ps. 22,653 Ps. 32,895 Ps. 29,703 Total hedge derivatives ​ Ps. 44,248 ​ Ps. 55,813 ​ Ps. 156,220 ​ Ps. 56,627 ​ ​

(6) Includes recognition of impairment Ps. 8,537 . (7) Includes recognition of impairment Ps. 100,797 (See note 17.1). ​ ​ The recoverable amount of each cash generating unit was determined based on market values of banks, listed in stock exchanges and a recoverable amount is determined by a study for those not listed in stock exchanges. Such calculations used cash flow projections, covering periods from 5 to 20 years. Cash flows subsequent to these periods were extrapolated using estimated growth rates for such flows, not exceeding the average of the economic sector where the cash generating unit operates. ​ Below is the detail of the most significant values that comprise Goodwill, representing more than 80% of the Goodwill balance detailed above: ​ A. BAC Holding International Corp. On December 9, 2010, Banco de Bogotá S.A. acquired control of BAC Credomatic Inc. (BAC COM) through its subsidiary BAC Holding International Corp. (BAC Holding), which is the Panamanian company that executed the purchase agreement. BAC Credomatic Inc. (BAC COM), a company incorporated to do business under the laws of the British Virgin Islands, is the owner of Banco BAC International Bank, Inc. and the operations of BAC Credomatic Inc. (BAC) in Central America. With the acquisition of BAC COM, through BAC Holding, BAC’s corporate structure now is controlled by Banco de Bogotá S.A., which is controlled, in turn, by Grupo Aval. Goodwill was generated and recognized as a result of that operation. Banco de Bogotá was authorized by the Superintendency of Finance to make this acquisition, through its subsidiary BAC Holding International Corp, as indicated in Official Notice 2010073017- 048 dated December 3, 2010. Later, 98.92% of the shares of Banco Bilbao Vizcaya Argentaria S.A. Panamá (BBVA Panamá, now BAC de Panamá) were acquired by Banco de Bogotá, through its subsidiary BAC Holding International Corp, under authorization from the Superintendency of Finance, as per Official Notice 2013072962-052 dated December 12, 2013. In addition, 100.00% of the shares of Banco Reformador de Guatemala (Reformador) and of Transcom Bank Limited in Barbados (Transcom) were acquired, and both banks were stated as Grupo Financiero Reformador de Guatemala. The Superintendency of Finance authorized Banco de Bogotá to acquire these banks, through its subsidiaries Credomatic International Corporation and BAC Credomatic Inc., as per Official Notice 2013068082-062 dated December 3, 2013. During 2015, Credomatic International Corporation, a subsidiary of the company, acquired 100% of the issued and outstanding shares of COINCA Corporation Inc. (COINCA) and Corporación Tenedora BAC Credomatic S.A., and an indirect subsidiary of the Company, acquired 100% of the issued and outstanding shares of Medios de Pago MP S.A., domiciled in Costa Rica, generating with the latter a capital gain of Ps. 853,401 that was included in the consolidated financial statements of the Bank in the first quarter of 2016. As of September 2021, Leasing Bogotá S.A Panama changed its corporate name to BAC Holding International Corp. and spun-off Multi Financial Group Inc. in favor of Banco de Bogotá through Multi Financial Holding (See note 1). In this sense, the goodwill of BAC Credomatic and its subsequent acquisitions were registered in BAC Holding International Corp. and the goodwill of Multi Financial Group Inc. in Multi Financial Holding. The latest valuation update for the groups of cash generating units to which this goodwill was allocated was carried out by an independent adviser and reviewed by Management in January 2022, based on the financial statements of BAC Credomatic on September 30, 2021. The conclusion was that there are no circumstances that could indicate a possible impairment, given that the recoverable amount of the groups of cash generating units associated with goodwill of Ps. 24,669,313 exceeds the book value by Ps.11,185,784. The following table shows the averages of the main assumptions used in the reports on impairment analysis of the cash-generating units with allocated goodwill, based on the impairment assessments carried out on the indicated dates. Although the valuation exercise includes a 10-years projection, the following tables only show the first 5 years as, following the first year of projection, rates are generally stable with no significant variations. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ 2022 2023 2024 2025 2026 ​ Lending rate on the loan portfolio and investments 9.1 % 9.1 % 9.1 % 9.1 % 9.1 % Borrowing rate 2.2 % 2.2 % 2.2 % 2.2 % 2.2 % Growth in income from commissions 1.6 % 6.6 % 5.8 % 5.4 % 5.3 % Growth in expenses 6.2 % 5.1 % 5.1 % 4.7 % 3.3 % Discount rate after taxes 11.8 % ​ Growth rate after ten years 3.0 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ 2021 2022 2023 2024 2025 ​ Lending rate on the loan portfolio and investments 10.1 % 10.1 % 10.1 % 10.1 % 10.2 % Borrowing rate 2.8 % 2.8 % 2.8 % 2.9 % 2.9 % Growth in income from commissions 3.8 % 8.4 % 7.6 % 6.3 % 6.7 % Growth in expenses 3.5 % 4.8 % 5.6 % 4.7 % 4.7 % Discount rate after taxes 12.3 % ​ Growth rate after ten years 3.0 % ​ ​ A 10-years projection was made to evaluate potential goodwill impairment, considering that the business will have matured and the flow of funds will have stabilized once this period has elapsed. In turn, macroeconomic assumptions as well as those for BAC Credomatic’s business in each of the countries where it operates were used for the projection, to reflect the contribution of each market to the CGUs as a whole. The averages of the main premises used are listed in the foregoing tables, including the variables for all the countries where BAC Credomatic Inc. operates. The following is description of that process: ● Lending rates on loans and investments were projected based on historical data and on the expectations of management in each of the countries where BAC Credomatic Inc. operates, considering the competitiveness of the different services in their respective markets and the growth strategies for each segment. The projection on US Federal Reserve rates was taken into account as well, since these rates serve as a basis for international banking rates. ● Growth in income from commissions was projected in line with the growth in BAC Credomatic´s active portfolio, which allows for greater income through products and services like insurance, memberships. commissions on foreign currency exchange and also the implementation of new services among others. Competitive markets were also considered in the projected time horizon elapsed. ● Although the functional or reporting currency of the business is that of each country in the region where BAC Credomatic Inc.´s. subsidiaries operate, the future flows of funds have been converted into nominal U.S. dollars in each projected period, discounted at a nominal rate in U.S. dollars, net of income tax, estimated as cost of equity ("Ke"). A discount rate in U.S. dollars is used, given that a consistent discount rate in the respective local currencies cannot be estimated due to of the lack of required data. ● The discount rate has been estimated considering of the risk profile of each of the markets where BAC Credomatic Inc. operates. ● To estimate the terminal value, the normalized flow of funds, adjusted according to growth expectations, was projected in perpetuity. This projection does not exceed the average long-term rate of growth for the economies in each of the countries where BAC operates. An annual growth rate of 3.0% was estimated for the long term. The after-tax discount rate used to discount the dividend flows reflects the specific risks relative to the CGU and the markets where BAC Credomatic operates, as mentioned earlier. Had the US dollar denominated estimated discount rate of 11.8% been 1.0% higher; it would not have been necessary to reduce the book value of goodwill, since the value-in-use of the cash-generating units associated with goodwill would have been Ps. 21,922,915 still exceeding book value as of December, 2021 of Ps. 13,483,529. B. Sociedad Administradora de Fondos de Pensiones y Cesantías Porvenir S.A . Porvenir absorbed AFP Horizonte Pensiones y Cesantías S.A. and the goodwill in question was allocated to the groups of cash-generating units that together made up Porvenir later that same year. The latest valuation update for the business lines of the groups of cash-generating units to which this goodwill was allocated, was done by an external adviser and reviewed by management. This valuation was conducted in January 2022 and is based on financial statements of Porvenir on September 30, 2021. The conclusion was that there are no situations that imply a possible impairment, given that the recoverable amount of the groups of cash generating units associated with goodwill was Ps. 5,310,260, exceeding the book value by Ps. 2,446,969. The following are the main assumptions used in the impairment test reports taken as the basis for impairment testing on the dates listed, even though the valuation exercise includes a 20-years projection, the following tables only shows the first 5 years as rates, following the first year of projection, are generally stable with no significant variations. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ 2022 2023 2024 2025 2026 ​ Interest rate on investments 6.1 % 4.7 % 4.4 % 4.6 % 4.6 % Borrowing rate 6.3 % 6.3 % 6.3 % 6.3 % 6.3 % Growth in income from commissions (7.8) % 7.0 % 4.5 % 6.0 % 5.6 % Growth in expenses (14.5) % (0.1) % 1.5 % 4.7 % 4.5 % Inflation 3.5 % 3.8 % 3.4 % 3.6 % 3.6 % Discount interest rate after taxes 12.5 % 12.6 % 12.6 % 12.6 % 12.6 % Growth rate after twenty years 3.5 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ 2021 2022 2023 2024 2025 ​ Interest rate on investments 4.9 % 4.3 % 4.6 % 4.3 % 4.3 % Borrowing rate 6.3 % 6.3 % 6.3 % 6.3 % 6.3 % Growth in income from commissions (8.9) % 8.4 % 7.1 % 7.1 % 6.4 % Growth in expenses (1.7) % 4.2 % (0.8) % 2.5 % 5.3 % Inflation 2.9 % 4.4 % 3.8 % 3.1 % 3.1 % Discount interest rate after taxes 13.6 % 13.4 % 13.4 % 13.4 % 13.4 % Growth rate after twenty years 3.4 % ​ ​ A 20-years projection was made to estimate goodwill based on macroeconomic assumptions and those related to the business of Porvenir, as indicated in the foregoing tables. The following is a description of that process. ● Investments and borrowing rates were projected using historical data and data provided by the Company on the business. ● The estimated increases in commissions and expenses are based on business growth and other transactions estimated by the Company. ● The inflation rate used in the projections is based on reports from outside sources, such as The Economist Intelligence Unit, and intra-group sources such as Corficolombiana´s research team. ● The growth rate used for the terminal value was 3.5% , which is the average projected inflation provided by the independent specialists. The after-tax discount interest rate that was used to discount dividend flows reflects the specific risks relative to each cash-generating unit. If the estimated discount rate of 12.5% had been 1.0% higher than the estimated rate in the valuation done by external experts, there would be no need to reduce the book value of goodwill, since the fair value of the groups of cash-generating units associated with goodwill would be Ps. 4,780,417 and still exceeding book value as of December, 2021 of Ps. 2,863,291. C. Cash-generating units inside Banco de Bogotá Goodwill was generated in 2006 with the acquisition of 94.99% of the shares of Banco de Crédito y Desarrollo Social – MEGABANCO S.A. and later merged with Banco de Bogotá. This operation was authorized by the Office of the Superintendency of Finance in Resolution No. 917 dated June 2, 2006 The latest valuation update for the business lines of the groups of cash-generating units to which this goodwill was allocated, was performed by an independent adviser and reviewed by management. This valuation was conducted in January 2022 and is based on Banco de Bogotá´s financial statements as of September 30, 2021. It was concluded that there are no situations that imply a possible impairment, given that the recoverable amount of the groups of cash generating units associated with goodwill was Ps. 9,166,267 exceeds the book value by Ps. 1,931,847. The following table shows the main assumptions used in the latest impairment tests of the groups of cash-generating units with allocated goodwill. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ 2022 2023 2024 2025 2026 ​ Lending rate on the loan portfolio and investments 7.8 % 8.4 % 8.6 % 8.7 % 8.7 % Borrowing rate 2.4 % 3.1 % 3.5 % 3.5 % 3.5 % Growth in income from commissions 10.2 % 7.5 % 9.1 % 9.8 % 10.7 % Growth in expenses 5.2 % 9.0 % 7.1 % 7.1 % 6.6 % Inflation 3.5 % 3.8 % 3.4 % 3.6 % 3.6 % Discount rate after taxes 12.5 % 13.2 % 13.2 % 13.2 % 13.2 % Growth rate after five years 3.6 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ 2021 2022 2023 2024 2025 ​ Lending rate on the loan portfolio and investments 6.7 % 8.0 % 9.0 % 9.5 % 9.6 % Borrowing rate 1.8 % 2.6 % 3.4 % 3.9 % 3.9 % Growth in income from commissions 15.7 % 44.0 % 8.8 % 8.5 % 8.6 % Growth in expenses 3.6 % 12.6 % 10.5 % 7.7 % 5.5 % Inflation 2.9 % 4.4 % 3.8 % 3.1 % 3.1 % Discount rate after taxes 13.0 % 12.8 % 12.8 % 12.8 % 12.8 % Growth rate after five years 3.3 % ​ ​ A 5-years projection was made to estimate goodwill, based on macroeconomic assumptions and those related to the businesses listed in the foregoing tables. The following is a description of that process. ● The lending rates on loans and investments were projected based on the Company expected rates and lending rates from independent specialists (The Economist Intelligence Unit "EIU") ● The borrowing rates were projected based on the Company´s expected rates and the money market interest rate from EIU. ● Estimated growth of commissions is based on its historical ratio to the gross loan portfolio. ● Estimated growth in expenses is based on the inflation’s growth and/or its historical percentage over revenues. ● The inflation rate used in the projections is based on reports from outside sources, such as The Economist Intelligence Unit, and intra-group sources such as Corficolombiana´s research team. ● The growth rate used for the terminal value was 3.6% , which is the average projected inflation provided by the independent specialists and reviewed by management. The discount rate after taxes used to discount dividend flows reflects the specific risks relative to each cash-generating unit. If the 12.5% estimated discount rate had been 1.0% higher than the rate estimated in the models, the book value of goodwill would not have to be impaired, since the fair value of the groups of cash-generating units associated with goodwill would have been Ps. 8,289,397, still exceeding book value as of December, 2021 of Ps. 7,234,420. ​ 17.1 Goodwill Impairment ​ Below is the detail of the most significant values that comprise impairment charge of Goodwill: ​ Concesionaria Víal del Pacífico ​ The recoverable amount for Concesionaria Vial del Pacífico S.A.S., has been calculated based on its value in use, determined by discounting the future free cash flows expected for the reminder of the concession term (from December 2021 to October 2043, the estimated time completion), using the estimated discount rate WACC 8.51% (8.7% as of December 2020), considering the company's cash and debt balances as of December 31, 2021. ​ Under the following assumptions, the recoverable amount as of Ps. 1,236,830 as of December 31, 2021, was lower than the carrying amount of the investment including its goodwill, generating an impairment of Ps. 100,797. The main assumptions and circumstances taken into account, which led to the recognition of this impairment were: ​ a. Covipacífico's income is made up of toll revenue, future government payments and payments for collection differences (shortfall in toll revenue is covered by top-up payments, called DR) if applicable. The estimate of said income to be received during the concession period is obtained from the combination of several elements: ​ o Average daily traffic (TPD for its acronym in Spanish) projections by category and application of the corresponding tariff per category, taking into account the updating method agreed in the concession contract. The tariff growth rate is regularly given by the variation observed in the CPI (IPC for its acronym in Spanish), and in some cases an additional growth is incorporated. ​ o Revenues from future government payments, agreed in constant pesos in the concession contract, are updated with the variation of the CPI corresponding to the period in which they are received by the concessionaire. ​ b. Internal projections of costs and expenses to be incurred for Administration, Operation and Maintenance are used, considering compliance with contractual obligations, as well as service level indicators. ​ c. Estimation of the discount rate: ​ o For December 2021, financial debt and equity are taken as a reference for the long-term capital structure of the company 60%-40%. o For the cost of debt, a weighted average of the following is used: 1 2 3 4 ​ o To calculate the Ke, the geometric average of the 10-year United States government bond yield was used as a reference for the risk-free rate, and the geometric average of the market premium was calculated, according to published data. on Aswath Damodaran's blog. The beta is calculated from the average beta of companies in the sector of emerging market countries. For the EMBI, the market value of the JP Morgan EMBI + is used. In this way, a nominal Ke in US$ of 11.6% (10% for December 2020) and a nominal Ke in COP of 11.8% are calculated. (10.1% for December 2020). ​

Banco de Occidente recorded a recovery of Ps. (63,849 ) and Banco Popular of Ps. (24,914 ). ​ 19.2 Reconciliation of the Nominal Tax Rate and the Effective tax Rate: The following are the existing legal provisions related to income tax: In Colombia The tax rules in relation to the income tax applicable during the years 2021, 2020 and 2019, among other things, establish the following: ​ ● The income tax rate to be 31% plus an income tax surcharge of 3% applicable to financial institutions in 2021, 32% plus an income tax surcharge of 4% applicable to financial institutions in 2020 and 33% in 2019. The income tax surcharge stipulated for 2019 was declared unconstitutional by the Constitutional Court of Colombia through Judgment C-510 of October 2019. ​ ● Gains on the sale or disposal of non-current assets held for more than two years is taxed at 10% . ● Gains of the entities that belong to the special free zone regime in Colombia is taxed at 20% . ​ ● The tax rate on presumptive income is calculated to 0.5% in the years 2020, 1.5% in the year 2019 and 3.5% in the years 2018. ● In 2020 and 2019, an income tax discount of 50% of the industry and commerce tax paid in the taxable period can be applied. This discount will increase to 100% in 2022. ​ ● Tax loss-carry forwards incurred prior to 2017 may be offset on the same terms applicable for 2016, but they may not be fiscally readjusted. Tax loss carry-forwards incurred since 2017 may be offset against company taxable income over the following twelve years. ● The “presumptive income” incurred prior to 2017 may be offset on the same terms applicable for 2016, but they may not be fiscally readjusted. The “presumptive income” incurred since 2017 may be offset by taxable income over the following five years. ​ ● As of 2017 the companies’ taxable income will be determined based on the new accounting regulation in force in Colombia since January 1, 2015. However, the new tax regulation also includes special income tax rules for several transactions. ​ The last tax reform that is in force at the time of preparation of these Financial Statements is Law 2155 of 2021. This Law, includes among others: ​ ● An income tax rate of 35% that applies to companies from 2022 onwards. In addition, financial institutions in Colombia with a taxable income equal to or greater than 120,000 Units of Tax Value - UVT (which by 2022 equals 36,308 pesos), are subject to a 3% income tax surcharge in 2022, 2023, 2024 and 2025. ​ ● An income tax discount of 50% of the industry and commerce tax paid in the taxable period. This eliminated the increase of this discount to 100% starting on in 2022, that was included in previous reforms. ● The audit benefit is extended for taxpayers that increase their net income tax of the taxable year relative to the net income tax of the immediately preceding year by at least 35% or 25%, limiting the tax authority's right to examine the income tax to 6 or 12 months from the date of its filing, respectively. ● The expiration of a tax authority's right to examine the income tax will be five years after the filing date for taxpayers that declare or compensate tax losses or that are subject to the transfer pricing regime. ​ In other countries Given that our subsidiary BAC Holding has an international license in Panamá it is subject to a tax rate of 0%. The subsidiaries in Guatemala are taxed at a rate of 25%; the subsidiaries in El Salvador, Honduras, Costa Rica and Nicaragua are taxed at a rate of 30% and the subsidiaries with a local license in Panamá are taxed at a rate of 25%. The subsidiaries in Perú are taxed at a rate of 29.5% since 2017.

Uncertain tax positions corresponding to expenses, considered deductible, and which, according to decisions of the tax authorities, could be considered as non-deductible. The balance as of December 31, 2020 is expected to be used fully or released when the inspection rights of the tax authorities with respect to the open tax returns expire. ​ 19.8 Withholdings tax on dividends paid between entities On December 28, 2018, some changes to tax on distribution of dividends were introduced by means of Law 1943. From there on, there is a new withholding tax (¨WHT") on distributions made to entities, which is treated as a tax credit deducted at source when a subsequent distribution is made by the entity to an individual. In essence, the tax credit resulting from the WHT is awarded to the ultimate beneficiary, no to the entity receiving the dividend in the first place. When the entity first receives the distribution, it accounts for the WHT in equity, as a reduction in dividends payable to individuals in accordance with paragraph 65A of IAS 12. Grupo Aval recorded WHT by Ps. 11,309 and Ps. 20,331 as of December 31, 2021 and 2020, respectively. The figure is not applicable with respect to payments made by BAC Holding, which is a foreign entity. ​

Disclosure of defined benefit plans [abstract]
EMPLOYEE BENEFITS	NOTE 22 – EMPLOYEE BENEFITS In accordance with labor legislation in the countries in which Grupo Aval operates, and based on labor conventions and collective bargaining agreements signed between Grupo Aval’s subsidiaries and their employees, employees have short term benefits (including but not limited to salaries, holidays, legal and extralegal premiums, interests on severances and defined contribution plans such as severances), long-term benefits (including but not limited to seniority bonuses), post-employment benefits (including but not limited to medical aids) and retirement benefits (including but not limited to severance payments to employees in Colombia who continue with labor regime before Law 50 of 1990 and legal and extralegal retirement pensions). Compensation of key management personnel (see note 34) includes salaries. Through personnel benefits plans, Grupo Aval is exposed to several risks (interest rates), which are intended to be minimized by applying the risk management policies and procedures defined under Note 4. The detail of the balance of liabilities for employee benefits as of December 31, 2021, and 2020 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 December 31, 2020 Short term Ps. 552,889 Ps. 462,070 Post-employment 522,196 ​ 597,936 Long term 134,831 ​ 180,090 Total ​ Ps. 1,209,916 ​ Ps. 1,240,096 ​ ​ ​ ​ ​ ​ ​ Plan Asset ​ Ps.

(38,241) ​ ​ ​ ​ ​ ​ ​ Net employee benefits Ps. 1,163,076 Ps. 1,201,855 ​ ​ ​ ​ 22.1 Post-employment benefits In Colombia, when employees retire after completing certain thresholds of years and time of service, retirement pensions are assumed by public or private pension funds based on defined contribution plans,. Entities and employees contribute monthly defined amounts by law to gain entitlement to a pension at the time of retirement. Unlike in Central America, in Colombia according to prior labor regimes, post-employment benefits for employees hired before (i) 1968 require pensions to be directly assumed the company for those employees that have fulfilled the requirements of age and years of service and (ii) 1990 entitle employees to receive a compensation equivalent to the last month of salary multiplied by each year of service. Some subsidiaries have labor conventions or pay extra-legal premiums to employees retiring in compliance with the required age and time of service, when they start enjoying the pension granted by the pension funds. Some retirees of Grupo Aval and its subsidiaries receive benefits including coverage of medical treatments. As of December 31, 2021 and 2020, the post-employment benefit expense is composed of: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ December 31, 2020 Defined contribution plan ​ Ps. 77,257 ​ Ps. 83,549 Defined benefit plan ​ ​ 48,857 ​ ​ 37,917 ​ ​ 22.2 Long Term Employee Benefits Some Grupo Aval subsidiaries grant their employees extra-legal long-term premiums during their working lives per every five years of service that they complete, calculated as days of salary per year of work. ​ Grupo Aval has recognized the liabilities corresponding to these benefits, based on the same actuarial calculations and using the same parameters as in retirement benefits. The following table shows the Post-employment and long-term benefits movements during the years ended on December 31, 2021, 2020 and 2019 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Post-employment benefits ​ Long-term benefits ​ December December December December December December ​ ​ 31, 2021 ​ 31, 2020 ​ 31, 2019 ​ 31, 2021 ​ 31, 2020 ​ 31, 2019 Balance at the beginning of the year Ps. 597,936 Ps. 590,914 Ps. 541,226 Ps. 180,090 Ps. 186,333 Ps. 242,335 Business combination (1) ​ ​ — ​ ​ 13,632 ​ ​ — ​ ​ — — — Service costs 15,606 ​ ​ 6,410 ​ ​ 14,567 ​ ​ 18,454 17,915 22,860 Interests cost 33,251 ​ ​ 32,745 ​ ​ 37,138 ​ ​ 7,982 8,563 14,252 Gain on settlements — ​ ​ (1,238) ​ ​ — ​ ​ — — — Past Service Costs (2) — ​ ​ — ​ ​ 1,018 ​ ​ (28,009) (15,659) (49,400) ​ Ps. 646,793 ​ Ps. 642,463 ​ Ps. 593,949 ​ Ps. 178,517 Ps. 197,152 Ps. 230,047 Changes in actuarial assumptions from changes in demographic assumptions 7,142 ​ ​ — ​ ​ 7,407 ​ ​ (1,493) — — Changes in actuarial assumptions from changes in financial assumptions (67,646) ​ ​ 7,835 ​ ​ 54,674 ​ ​ (21,462) 11,449 (13,008) ​ Ps.

For those entities where a sufficiently long statistic history is not yet available to support the actuarial bases, the SoA2003 table is used as a reference. With this table, the probability of permanence of personnel in the entity is established, modified according to the population factor of each benefit. Employee´s life expectancy is calculated based on the mortality tables RV08 (Colombia) and GA83 (Central America). ​ The sensitivity analysis for post-employment and long-term benefits liabilities due to defined benefits plans to different actuarial and financial variables is shown below, maintaining other variables at constant values (increase or decrease 50 basis points): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ -0.50 basic points ​ +0.50 basic points At December 31, 2021 Post-employment benefits Long-term benefits ​ Post-employment benefits Long-term benefits Discount interest rate Ps. 17,436 Ps. 3,258 ​ Ps.

Disclosure of commitments and contingencies [abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 27 – COMMITMENTS AND CONTINGENCIES ​ Capital expenses commitments As of December 31, 2021, and December 31, 2020, Grupo Aval and its subsidiaries had contractual disbursement commitments of capital expenditures, for tangible assets for Ps. 98,110 and Ps. 65,210, respectively; and for intangible assets for Ps. 129,465 and Ps. 92,816, respectively. ​ Contingencies As of December 31, 2021, and 2020, Grupo Aval and its subsidiaries were part of administrative and legal proceedings as defendants; the claims of proceedings were assessed based on analyses and opinions of seasoned lawyers. The following legal contingencies were determined: Labor Proceedings As of December 31, 2021, and December 31, 2020, the outstanding balances recognized for labor complaints amounted to Ps. 139,698 and Ps. 88,848, respectively. Historically, many of these proceedings have been resolved in favor of Grupo Aval and its subsidiaries. ​ Civil Proceedings As of December 31, 2021, and December 31, 2020, the result of the assessment of claims for civil suits, not including those with remote probability, reached outstanding balances recognized of Ps. 251,523. As of December 31, 2020 these amounted to Ps. 395,192, respectively, of which Ps. 107,898 correspond to processes acquired through the Multi Financial Group Inc. (MFG). ​ ​ Administrative, Tax Proceedings and Other Proceedings Claims derived from administrative and judicial processes include those of fiscal responsibility over concession contracts, tax proceedings and other, filed by national and local tax authorities. These authorities may establish, in some cases, sanctions in which Grupo Aval and its subsidiaries may incur as a result of: (i) the performance of their duty as a withholder or collector of national and local taxes, and/or (ii) the obligation to pay a higher tax amount in their condition of taxpayers. As of December 31, 2021, the outstanding balances recognized for these claims amounted to Ps. 138,418. As of December 31, 2020, these amounted to Ps. 101,700, of which Ps. 3,748 correspond to processes acquired through the Multi Financial Group Inc. (MFG). ​ Other matters ​ The outcomes of the following legal processes cannot be necessarily classified as “possible” in accordance with IAS 37, however, they are being disclosed herein in consideration of their relevance. ​ Class Action before the Administrative Tribune of Cundinamarca in connection with the Ruta del Sol Sector 2 Project ​ On January 26, 2017, the Inspector-General’s Office (Procuraduría General de la Nación or “PGN”) filed a class action against CRDS, (a company formed by Constructora Norberto Odebrecht S.A., Odebrecht Investimentos em Infraestructura Ltda., CSS Constructores S.A. and Episol), the National Infrastructure Agency ("ANI") and its members, for allegedly violating the collective rights of administrative morality, defense of public patrimony, and access to public services in connection with the Ruta del Sol Sector 2 project. On December 6, 2018, the Administrative Tribunal of Cundinamarca (“TAC”), the body presiding over the class action, issued a first instance ruling against CRDS, and all its shareholders, including Episol, and other individuals and entities. The TAC found the defendants jointly and severally liable for the damages caused to the collective interests and ordered the payment of Ps. 800,156 to the Colombian Ministry of Transportation. The TAC also debarred the defendants for a term of ten years, during which time they would be prohibited from contracting with the Colombian government and holding public office. Subsequently, in an order dated February 8, 2019, the TAC corrected certain arithmetical errors in its ruling, and reduced the amount of the fine to Ps. 715,656. ​ The aforementioned ruling is not final and appeals were filed by Episol and the other defendants, which were granted by the TAC on February 25, 2019 and will be heard by the Consejo de Estado (Colombia’s Supreme Court on administrative matters). On February 14, 2020, the Consejo de Estado issued a ruling regarding the effects of the appeal, specifying that the provisions of the first instance ruling regarding the delivery of money or other goods as well as the debarment from government contracting would only become enforceable in the event of a final second instance ruling by the Consejo del Estado confirming the decision under appeal. ​ In the case of Episol, its appeal filing seeks revocation of the TAC’s first instance ruling against it on the basis of multiple substantive and procedural defects. ​ It is not possible to establish how much time it will take for the Consejo de Estado to make a decision in relation to this case. In the event that the decision of the TAC is confirmed and Episol is compelled to assume the entire amount of the penalty, the maximum impact to the net attributable profit of Grupo Aval would be Ps. 286,104. ​ Investigations by United States authorities ​ In late 2018, the Department of Justice of the United States ("DOJ") and the United States Securities and Exchange Commission ("SEC") informed Grupo Aval that they had opened an investigation on matters related to the Ruta del Sol Sector 2 project. Grupo Aval is cooperating with the DOJ and the SEC in these investigations. It is not possible to predict the decisions that the DOJ or the SEC will take as a result of the issues that are the subject of these investigations, nor the impact that such investigations and their outcome may have on Grupo Aval and / or its subsidiaries. ​ ​ ​

Disclosure of operating segments [abstract]
ANALYSIS OF OPERATING SEGMENTS	NOTE 31 – ANALYSIS OF OPERATING SEGMENTS Operating segments are components of Grupo Aval responsible for developing commercial activities that can generate revenue or incur expenses and whose operating profit or loss are regularly reviewed by the chief operating decision maker (“CODM”) of Grupo Aval, and for which financial information is available. Operating segment information is consistent with the internal reports provided to the CODM. ​ 31.1 Description of products and services from which each reportable segment derives its income Grupo Aval is organized into seven main operating segments comprised by the five main banking operations (Banco de Bogotá S.A., BAC Holding International Corp., Banco de Occidente S.A., Banco AV Villas S.A., Banco Popular S.A.), Corficolombiana S.A. and Porvenir. Banco de Bogotá S.A., Banco de Occidente S.A., Banco Popular S.A. and Banco AV Villas S.A.: These operating segments provide financial services to companies, individuals and Government organizations mainly in Colombia such as: wholesale and retail lending, financial leasing, treasury operations, proprietary trading, trust, logistics and bonded warehouse services, among other. BAC Holding International Corp. (“BAC Holding”): This operating segment consolidates BAC Holding’s operations, mainly in Central America. It derives its income from financial services provided by its main subsidiaries, BAC Credomatic Inc., to companies, individuals and Government organizations in Costa Rica, Panama, Guatemala, Honduras, El Salvador and Nicaragua such as: wholesale and retail lending, financial leasing, treasury operations, proprietary trading, pension fund management, brokerage, among other. Sociedad Administradora de Fondos de Pensiones y Cesantías Porvenir S.A. (“Porvenir”): Is the leading private pension fund manager in Colombia in terms of assets under management and has the largest share of earnings in the private pension and severance fund management market in Colombia. Corficolombiana S.A.: This operating segment consolidates all of Corficolombiana’s subsidaries. It provides both financial and non-financial services to companies, individuals and Government organizations, mainly in Colombia and Peru. It derives its income from financial services such as: retail lending, treasury operations, proprietary trading, brokerage and trust services, among other. It derives its income from non-financial services from 5 main sectors: Energy & gas (transportation and distribution of natural gas and energy), infrastructure (concession arrangements, mainly in road infrastructure), hotels (hospitality services) and agribusiness (mainly palm oil and rubber). 31.2 Factors used by management to identify reportable segments Operating segments identified above are based on the relevance of factors such as (i) the nature of the products and services provided and (ii) the geographical locations. Information regarding the performance of operating segments is reviewed by the CODM on a quarterly basis. ​ Per the organizational changes detailed in Note 1, during 2021 the Company implemented a new reporting segment structure. With this change, (i) Porvenir became a new reporting segment separately from the Banco de Bogota reporting segment, (ii) Leasing Bogotá S.A. Panamá (LB Panama) reporting segment denomination was changed to BAC Holding International Corp. (BAC Holding), and (iii) Multi Financial Group Inc. (MFG) was transferred from BAC Holding to be included into the Banco de Bogota reporting segment. ​ With respect to the previous period and as required by IFRS 8 "Operating Segments", the reported figures have been modified to be consistent with 2021. ​ 31.3 Measurement of net income, assets and liabilities of operating segments Grupo Aval’s CODM reviews the financial information of each of its operating segments and assesses the performance of each segment based on Statements of Financial Position and the Statement of Income of each of them, and on certain credit risk indicators, as described in note 2.29 ​ 31.4 Information on net income, assets and liabilities of reportable operating segments The following is the detail of the reportable financial information summarized for each segment as of December 31, 2021, 2020 and 2019: ​ Statement of Financial Position ​ December 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Banco de ​ BAC Holding ​ Banco de ​ Banco ​ Banco AV ​ Porvenir ​ Corficolombiana ​ Other ​ ​ ​ ​ ​ ​ Bogotá S.A. ​ International Corp (1) ​ Occidente S.A. ​ Popular S.A. ​ Villas S.A. ​ S.A. ​ S.A. ​ segments (2) ​ Eliminations ​ Total Assets ​ ​ ​ ​ Trading assets Ps. 2,480,205 Ps. 190,340 Ps. 1,655,678 Ps. 354,037 Ps. 249,071 Ps. 2,493,514 Ps. 3,664,843 Ps. 49 Ps.

Disclosure of transfers of financial assets [abstract]
TRANSFERS OF FINANCIAL ASSETS	NOTE 33 - TRANSFERS OF FINANCIAL ASSETS Grupo Aval enters into transactions in its normal course of business by which it transfers financial assets to third parties. Depending on the circumstances, these transfers may either result in these financial assets being derecognized or continuing to be recognized in Grupo Aval´s financial statements. A. Transferred financial assets not qualifying for full derecognition i. Sale and repurchase agreements Sales and repurchase agreements are transactions in which Grupo Aval sells securities and simultaneously agrees to repurchase them (or assets that are substantially the same) at a fixed price on a future date. Grupo Aval continues to recognize the securities in their entirety in the statement of financial position because it retains substantially all of the risks and rewards of ownership. The cash consideration received is recognized as a financial asset and a financial liability is recognized for the obligation to pay the repurchase price. Because Grupo Aval sells the contractual rights to the cash flows of the securities, it does not have the ability to use the transferred assets during the term of the arrangement. As of December 31, 2021, the financial assets held for trading that are being used as collateral under repurchase agreements amounted to Ps. 2,238,565 (December 31, 2020 Ps.1,451,572) see note 5.1.1 (only pledged as collateral in money market operations and pledged as collateral to special entities such as CRCC, BR and BVC), the financial investments debt securities at amortized cost that are being used as collateral under repurchase agreements amounted to Ps.361,388 (December 31, 2020 Ps.825,407) see note 9.3.1 and the financial investments debt securities FVOCI that are being used as collateral under repurchase agreements amounted to Ps. 8,444,486 (December 31, 2020 Ps. 5,727,908) see note 5.1.2 (only pledged as collateral in money market operations and pledged as collateral to special entities such as CRCC, BR and BVC). ii.

Disclosure of detailed information about business combination [abstract]
BUSINESS COMBINATION	NOTE 35 – BUSINESS COMBINATION On May 22, 2020, BAC Holding International Corp. (BAC Holding) (before, Leasing Bogotá S.A. Panamá), a subsidiary of Banco de Bogotá, acquired Multi Financial Group Inc. (MFG). The acquired Group was comprised mainly of Multibank Inc. and subsidiaries. MFG provides a wide variety of financial services, mainly corporate banking, investment, mortgage and consumer banking, as well as insurance, securities brokerage, factoring, leasing and real estate services. The purchase price was Ps. 1,613,408 (US$433.8 million) paid in cash on May 22, 2020, for thus acquiring 96.6% of the ordinary and outstanding shares. Non-controlling interest recognized for Ps. 465,902 (US$125 million) includes Ps. 409,070 (US$110 million) in preferred shares that were not included in the share purchase agreement. ​ In September 2020, BAC Holding received a refund for an amount of Ps. 6,334 (US$ 1.6 million) as an adjustment to the price paid which had included items that should not have been included in the transaction. The final adjusted purchase price is Ps. 1,607,074 (US$432.2 million). ​ MFG’s consolidated results have been recognized in Grupo Aval´s consolidated financial statements from the date BAC Holding obtained control. The acquisition was mainly carried out in order to increase BAC Holding´s operation through future business potential, strengthening the leadership position in Panamá, the synergies and economies of scale expected from operations and of MFG with this transaction being complementary to the lines of business in which the BAC Holding already participates in Panamá. The goodwill has been allocated to MFG as a single operating segment. The recognized goodwill is not deductible for tax purposes. ​ For the period between the acquisition date and December 31, 2020, MFG contributed revenues of Ps. 684,682 (US$197.4 million) and profits of Ps. 23,239 (US$6.7 million) to the Group´s consolidates results. If the acquisition had occurred on January 1, 2020, the Grupo Aval estimates that consolidated revenues would have been Ps. 38,949,821 (US$11,215 million), and consolidated net income for the year ended December 31, 2020 would have been Ps. 4,486,044 (US$1,298 million). In determining these amounts, Grupo Aval has assumed that the determined fair value adjustments that arose at the acquisition date would have been the same had the acquisition occurred on 1 January 2020. ​ The Company incurred costs related to the acquisition of Ps. 2,701 (US$0.78 million) for legal fees, valuation fees and due diligence costs. These costs have been included under "administrative costs".

Certain information and footnote disclosures normally included in financial statements prepared in accordance with IFRS have been condensed or omitted for immaterial. The separated financial statements of Grupo Aval have been prepared using the same IFRS basis and principles that Grupo Aval used to prepare it consolidated financial statements described in Note 2. Commitments and contingencies In the normal course of business, certain subsidiaries of Grupo Aval are defendants in various tax and legal proceedings. Grupo Aval is not aware of any pending legal proceedings which could have a significant effect on its financial position or the results of its operations. Investment in subsidiaries and associates companies Based on the IAS 27, when an entity prepares separate financial statements it shall account for investments in subsidiaries either: a) at cost or b) at fair value, in accordance with IFRS 9 or c) using the equity method. Accordingly Grupo Aval accounts for its investments in subsidiaries using the equity method. The equity method is an accounting method according to which the investment is initially recognizes at cost, and they are periodically adjusted due to changes in the interest of the parent company over the net assets of the subsidiaries. Grupo Aval records on the result of the period its participation in the profit or loss of the subsidiaries, and in OCI its participation in the “Other comprehensive income account” of the subsidiary. In applying equity method Grupo Aval uses the subsidiaries consolidated financial statements at the end of the period prepared under IFRS. Investment in Subsidiaries and Associates Investment in subsidiaries and associates as of December 31, 2021 and 2020 comprise the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ December 31, 2020 ​ Ownership ​ ​ Ownership ​ ​ ​ interest held ​ ​ ​ ​ interest held ​ ​ ​ ​ by Grupo ​ Book ​ by Grupo ​ Book Subsidiary ​ Aval ​ Value ​ Aval ​ Value Banco de Bogotá S.A. 68.74 % Ps. 15,616,990 68.74 % Ps. 13,601,445 Banco de Occidente S.A. 72.27 % 3,632,129 72.27 % 3,494,268 Banco Comercial AV Villas S.A. 79.87 % 1,479,917 79.87 % 1,473,996 Banco Popular S.A. 93.74 % 3,318,617 93.74 % 3,186,389 Corporación Financiera Colombiana S.A. 39.98 % 1,061,518 39.58 % 973,650 Sociedad Administradora de Fondos de Pensiones y Cesantías Porvenir S.A. 75.67 % 570,941 75.67 % 564,256 Grupo Aval Limited 100.00 % (658,519) 100.00 % (611,064) Sociedad Beneficiaria Aval S.A.S. ​ 100.00 % — ​ — % ​ — Sociedad Beneficiaria Bogotá S.A.S. ​ 100.00 % — ​ — % ​ — Total subsidiaries ​ ​ Ps. 25,021,593 ​ ​ Ps. 22,682,940 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Associates ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ADL Digital Lab S.A.S ​ 34.00 % ​ 4,014 ​ 34.00 % ​ 1,929 Total associates ​ ​ ​ ​ 4,014 ​ ​ ​ ​ 1,929 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total investment in subsidiaries and associates ​ ​ ​ Ps. 25,025,607 ​ ​ ​ Ps. 22,684,869 ​ ​ ​ Outstanding bonds Outstanding bonds at December 31, 2021 and 2020 comprise the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amounts outstanding Issuance date Tranches Maturity Coupon rate 2021 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ November, 2019 Ps. 100,000 November, 2024 6.42 % Ps. 100,825 Ps. 100,825 November, 2019 300,000 November, 2039 IPC + 3.69 % ​ 303,229 302,126 June, 2017 ​ ​ 300,000 ​ June, 2042 ​ IPC + 3.99 % ​ 300,301 ​ ​ 300,178 November, 2016 93,000 November, 2026 IPC + 3.86 % ​ 93,810 93,538 November, 2016 207,000 November, 2036 IPC + 4.15 % ​ 208,861 208,259 December, 2009 124,520 December, 2024 IPC + 5.20 % ​ 125,542 125,173 Total Bonds Ps. 1,124,520 ​ ​ Ps. 1,132,568 Ps. 1,130,099 ​ The scheduled maturities of bonds as of December 31, 2021 are as follows: ​ ​ ​ ​ ​ Period Amount 2022 8,048 2023 — 2024 and thereafter 1,124,520 Total Ps. 1,132,568 ​

BASIS OF PREPARATION OF THE C_2

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2021
Disclosure of voluntary change in accounting policy [abstract]
Disclosure of basis of consolidation [text block]	2.1 Basis of preparation a) The Consolidated Financial Statements are prepared as follows: ​ ● The Consolidated Statement of Financial position presents the company´s assets and liabilities based on liquidity since it provides reliable and more relevant information than separate current and non-current classifications. ​ ● The Consolidated Statements of Income and Other Comprehensive Income are presented separately. The Consolidated Statement of Income is presented according to the function of expenses, as this method provides reliable and more relevant information. ​ ● The Consolidated Statement of Cash Flows is presented using the indirect method. Accordingly, net cash flows from operating activities are determined by reconciling net income before tax expense, with the effects of non-cash items, net changes in assets and liabilities from operating activities, and for any other effects that are not classified as investing or financing activities. Revenues and expenses due to interest received and paid are part of operating activities. ​ b) Consolidated Financial Statements ​ Grupo Aval prepares its Consolidated Financial Statements incorporating its controlled entities. Grupo Aval controls an investee if and only if it complies with the following elements: ​ ● Power over the investee entitling Grupo Aval to direct any relevant activities that significantly affect the investee's performance. ● Exposure, or rights to variable returns from its involvement with the investee. ● Ability to affect those returns through its power over the investee. ​ Grupo Aval carries out of all its contractual relationships, for the year 2021, no new entities were identified to be consolidated and with the year 2020 in the evaluation carried out a business combination was identified (see note 35). ​ The financial statements for Grupo Aval´s subsidiaries are included in the consolidated financial statements since the date on which Grupo Aval acquires control or following control until the date on which control is lost. ​ During the consolidation process, Grupo Aval combines the assets, liabilities and profits or losses of those entities under control, previously aligning the accounting policies in all the subsidiaries and translating its financial statements to Colombian Peso. This process includes eliminating intra-group balances and transactions and any unrealized and realized income and expense (except for foreign currency translation gains or losses and those taxes which are not subject to elimination) arising from intra-group transactions. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment. Non-controlling interests are presented under total equity in the Consolidated Statement of Financial Position of Grupo Aval separately from equity attributable to owners of the parent company. For consolidation purposes, the Statements of Financial Position and Income of entities with a functional currency different form Grupo Aval´ are translated to Colombian pesos as follows: ● Assets and liabilities are translated at the closing exchange rate at the reporting date; ● Income, expense and cash flows are translated at the corresponding month’s average exchange rate since they approximate the exchange rates of each specific transaction; ● All resulting exchange differences are recognized in other comprehensive income and accumulated in the foreign currency translation reserve, except to the extent that the translation difference is allocated to non-controlling interests. ​ c) Investments in associates ​ Associates are companies in which Grupo Aval has significant influence but not control and are accounted for under the equity method. They are presented in the statement of financial position as “Investments in associates and joint ventures” (see Note 2.1 “d Joint arrangements”). Grupo Aval exercises significant influence over another entity if it owns, directly or indirectly, 20% or more of the voting power of the investee, unless it is clearly evidenced that such influence does not exist. They are initially recognized at cost, which includes transaction costs. Subsequent to initial recognition, the Consolidated Financial Statements include the Grupo Aval’s share of the profit or loss and OCI of equity accounted investees, until the date on which significant influence or joint control ceases. ​ Dividends received from associates and joint ventures are recognized as a lower value in the carrying amount of the investment. ​ In the case that Grupo Aval´s share of losses in an equity-accounted investment equals or exceeds its interest in the entity, including any other unsecured long-term receivables, Grupo Aval does not recognize further losses, unless it has incurred obligations or made payments on behalf of the other entity. ​ Unrealized gains on transactions between Grupo Aval and its associates are eliminated to the extent of Grupo Aval’s interest in these entities. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. ​ Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by Grupo Aval. ​ The carrying amount of associates are tested for impairment. ​ d) A joint arrangement is one in which two or more parties have joint control of the arrangement. Joint arrangements are divided into joint operations or joint ventures. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement, under joint operations the parties having joint control of the agreement have rights to the assets and obligations to the liabilities relating to the agreement. Under joint ventures, the parties having joint control, are entitled to the net assets of the agreement. Grupo Aval recognizes joint operations in the consolidated financial statements based on their proportional and contractual participation in each of the assets, liabilities and profit or loss of the contract or entity wherein the agreement is held. Grupo Aval recognizes joint ventures through the equity method, in the same manner as investments in associates. ​
Description of accounting policy for functional currency [text block]	2.2 Functional and presentation currency ​ Considering that the majority of the Group´s business activities as well as the generation and use of cash is in Colombian pesos, the Colombian peso is the currency that most accurately represents the economic environment of Grupo Aval’s operations, both for the consolidated financial statements and for the parent company. Foreign entities have functional currencies different from the Colombian peso, which are translated to Colombian pesos for presentation purposes. The main functional currency these foreign entities is the US dollar. ​ ​
Description of accounting policy for foreign currency translation [text block]	2.3 Transactions in foreign currencies ​ Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the prevailing exchange rate at the reporting date. Non-monetary assets and liabilities denominated in foreign currencies in terms of historical costs are measured using the exchange rate at the transaction date. Financial instruments measured at fair value are converted using the exchange rate at the date the fair value was determined. Profits or losses resulting from the translation process are recognized in profit or loss, except for financial instruments designated as hedging instruments. ​ As of December 31, 2021 and 2020, the representative market rates as computed and certified by the Superintendency of Finance (for the U.S. dollar which is the most representative foreign currency for Grupo Aval´s transactions) were Ps. 3,981.16 and Ps. 3,432.50 per U.S. $1, respectively.
Description of Accounting Policy for Operating segments [Policy Text Block]	2.4 Operating segments ​ An operating segment is a component of an entity which: ​ a) Engages in business activities from which it can earn revenue and incur expenses (including revenue and expenses from transactions with other components of the same entity); b) Operating profit or losses are regularly reviewed by the chief operating decision maker, who decides on the resources allocation to the segment and assesses its performance and. c) Discrete financial information is available, Segment results that are reported to the CODM include items that are directly attributable to a segment as well as those that can be allocated on a reasonable basis. Management evaluates regularly the performance for each segment; Grupo Aval discloses information separately for each identified operating segment, meeting any of the following quantitative thresholds: a) The segment´s reported revenue from the ordinary activities, including revenue from external customers as well as revenue from intersegment transfers, is equal or greater than 10% of the revenue of combined ordinary activities, internal and external, of all operating segments. b) The amount of the segment´s reported net income is, in absolute terms, equal or greater than 10% of the amount greater of: (i) the combined reported net income of all the segments not reporting a loss; and (ii) the reported combined loss of all segments of the operations with incurred losses. c) The segment´s assets are equal to or greater than 10% of the combined assets of all segments of the operation. The information regarding other activities of the business of operating segments that do not have to be reported is combined and disclosed within the category of “Others”.
Description of Accounting Policy For Financial Assets and Financial Liabilities [Policy Text Block]	2.5 Financial assets and financial liabilities ​ i. Recognition and initial measurement ​ Grupo Aval initially recognizes loans and advances, deposits, debt securities issued and subordinated liabilities on the date on which they are originated. All other financial instruments (including regular-purchases and sales of financial assets) are recognized on the trade date, which is the date in which Grupo Aval becomes a party to the contractual provisions of the instrument. A financial asset or financial liability is initially measured at fair value. Additionally, for instruments measured at amortized cost or Fair Value Through Other Comprehensive Income (“FVOCI”), transaction costs are added if directly attributable to its acquisition or issuance. ii. Classification ​ Financial assets ​ On initial recognition, a financial asset is classified as: amortized cost, Fair Value Through Other Comprehensive Income (“FVOCI”) or Fair Value Through Profit or Loss (“FVTPL”). ​ A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL: ● The asset is held within a business model in which the objective is to hold assets to collect contractual cash flows; and ● The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. A debt instrument is measured at FVOCI only if it meets both of the following conditions and is not designated as at FVTPL: ● The asset is held within a business model whose objective is achieved both by collecting contractual cash flows and selling the financial asset; and ● The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. On initial recognition of an equity investment that is not held for trading, Grupo Aval may irrevocably elect to present subsequent changes in fair value in Other Comprehensive Income (“OCI”). This election is made on an investment-by-investment basis. All other financial assets are classified and measured at FVTPL. Business model assessment ​ Grupo Aval makes an assessment of the objective of a business model in which an asset is held at a portfolio level because this best reflects the way the business is managed, and information is provided to management. The information considered includes: ​ ● The established policies and objectives for the portfolio and their actual application. In particular, whether management’s strategy focuses on earning contractual interest revenue, maintaining a particular interest rate profile, matching the duration of the financial assets to the duration of the liabilities that are funding those assets; ● How the performance of the portfolio is evaluated and reported to Grupo Aval’s management; ● The risks that affect the performance of the business model (and the financial assets held within that business model) and how those risks are managed; and ● The frequency, volume and timing of sales of financial assets in prior periods, the reasons for such sales and its expectations about future sale activity. However, information about sales activity is not considered in isolation, but as part of an overall assessment of how Grupo Aval’s stated objective for managing the financial assets is achieved and how cash flows are realized. Financial assets that are held for trading, for which performance is evaluated on a fair value basis are measured at FVTPL because their objective is neither to collect contractual cash flows nor to collect contractual cash flows and sell the financial assets. ​ Assessment whether contractual cash flows are solely payments of principal and interest (SPPI) ​ For the purposes of this assessment, “principal” is defined as the fair value of the financial asset on initial recognition. “Interest” is defined as consideration for the time value of money and for the credit risk associated with the principal amount outstanding during a particular period of time and for other basic lending risks (e.g. liquidity risk and administrative costs), as well as profit margin. ​ In assessing whether the contractual cash flows are solely payments of principal and interest (SPPI), Grupo Aval considers the contractual terms of the instrument. This includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet this condition. Upon assessment Group Aval considers: ​ ● Contingent events that would change the amount and timing of cash flows; ● Leverage covenants; ● Prepayment and extension terms; ● Terms that limit Grupo Aval’s claim to cash flows from specified assets; and ● Features that modify consideration of the time value of money. ​ Interest rates on certain commercial and consumer loans originated by Grupo Aval are pegged to standard variable rates generally used in each country where Grupo Aval operates and includes a spread. In Colombia, the standard variable rates are based on the DTF (rate interest calculated as the average for time deposits)s or the interbank rate (in Spanish Interés Bancario de Referencia), or “IBR” rates, both of which are calculated weekly by the Central Bank based on information collected from the Colombian financial system, plus a spread, and in the case of loans in foreign currency issued in Colombian entities and in other countries Grupo Aval uses LIBOR interest rates plus a spread. See Note 4 – “Interest rate benchmark reform”. ​ In these cases, Grupo Aval assesses whether the discretionary feature is consistent with the SPPI criteria by considering a number of factors, including whether: ​ ● Borrowers are able to prepay the loans without significant penalties, ● Market competition ensures that interest rates are consistent between banks, and ● Any regulatory or customer protection framework is in place that requires banks to treat customers fairly. A prepayment feature is consistent with the SPPI criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable compensation for early termination of the contract. ​ In addition, a prepayment feature is treated as consistent with this criterion if a financial asset is acquired or originated at a premium or discount to its contractual par amount, and the prepayment amount substantially represents the contractual par amount plus accrued (but unpaid) contractual interest (which may also include reasonable compensation for early termination), and the fair value of the prepayment feature is insignificant upon initial recognition. ​ Financial liabilities ​ Grupo Aval classifies its financial liabilities, other than derivatives, financial guarantees and loan commitments, as measured at amortized cost. ​ iii. Reclassifications ​ ​ Financial assets ​ Financial assets are not reclassified subsequent to their initial recognition, except in the period after Grupo Aval’s entities changes their business model for managing financial assets. iv. Derecognition ​ ​ Financial assets ​ Grupo Aval derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire (see also (v)), or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which Grupo Aval neither transfers nor retains substantially all of the risks and rewards of ownership but it does not retain control of the financial asset. ​ At derecognition of a financial asset, the difference between the carrying amount of the asset (or the carrying amount allocated to the portion of the asset derecognized) and the sum of (i) the consideration received (including any new asset obtained less any new liability assumed) and (ii) any cumulative gain or loss that had been recognized in OCI is recognized in profit or loss. Any cumulative gain/loss recognized in OCI in respect of equity investment securities designated as at FVOCI is not recognized in profit or loss on derecognition of such securities, as explained in (2.10). Any interest in transferred financial assets that qualify for derecognition that is created or retained by Group Aval is recognized as a separate asset or liability. Grupo Aval enters into transactions whereby it transfers assets recognized on its statement of financial position but retains either all or substantially all of the risks and rewards of the transferred assets or a portion of them. In such cases, the transferred assets are not derecognized. Examples of such transactions are securities lending and sale-and-repurchase transactions. When assets are sold to a third party with a concurrent total rate of return swap on the transferred assets, the transaction is accounted for as a secured financing transaction similar to sale-and repurchase transactions, given that Grupo Aval retains all or substantially all of the risks and rewards of ownership of such assets. In transactions in which it neither retains nor transfers substantially all of the risks and rewards of ownership of a financial asset and it retains control over the asset, Grupo Aval continues to recognize the asset to the extent of its continuing involvement, determined by the extent to which it is exposed to changes in the value of the transferred asset. Financial liabilities ​ Grupo Aval derecognizes a financial liability when its contractual obligations are discharged or cancelled or expire. ​ ​ v. Modifications of financial assets and financial liabilities ​ Financial assets ​ If the terms of a financial asset are modified, then Grupo Aval assesses whether the cash flows of the modified asset are substantially different. ​ If the cash flows are substantially different, the contractual rights to cash flows from the original financial asset are deemed to have expired. In that case, the original financial asset is derecognized (see (iv)) and a new financial asset is recognized at fair value plus any eligible transaction costs. Any fees received as part of the modification are accounted for as follows: ● Fees that are considered in determining the fair value of the new asset and fees that represent reimbursement of eligible transaction costs are included in the initial measurement of the asset; and ● Other fees are included in profit or loss as part of the gain or loss on derecognition. ​ If cash flows are modified when the borrower is in financial distress, the objective of the modification is usually to maximize recovery of the original contractual terms rather than to originate a new asset with substantially different terms. If Group Aval plans to modify a financial asset in a way that would result in foregoing of cash flows, it considers whether a portion of the asset should be written off before the modification takes place (see below for write‑off policy). This approach impacts the result of the quantitative evaluation and means that the derecognition criteria are not usually met in such cases. ​ If the modification of a financial asset measured at amortized cost or FVOCI does not result in derecognition of the financial asset, then Grupo Aval recalculates the gross carrying amount of the financial asset using the original effective interest rate of the asset and recognizes the resulting adjustment as a recovery or impairment in the Consolidated Statement of Income. For variable-rate financial assets, the original effective interest rate used to calculate the modification gain or loss is adjusted to reflect current market terms at the time of the modification. Any costs or fees incurred, and fees received as part of the modification are incorporated into the gross carrying amount of the modified financial asset and are amortized over the remaining term of the modified financial asset. ​ Financial liabilities ​ Grupo Aval derecognizes a financial liability when its terms are modified, and the cash flows of the modified liability are substantially different. In this case, a new financial liability based on the modified terms is recognized at fair value. The difference between the carrying amount of the financial liability extinguished and the new financial liability with modified terms is recognized in the Consolidated Statement of Income. ​ If the modification of a financial liability measured at amortized cost does not result in derecognition of the financial liability, then Grupo Aval first recalculates the gross carrying amount of the financial liability using the original effective interest rate of the liability and recognizes the resulting adjustment as interest expense in the Consolidated Statement of Income. For variable-rate financial assets, the original effective interest rate used to calculate the modification gain or loss is adjusted to reflect current market terms at the time of the modification. Any costs or fees incurred, and fees received as part of the modification are incorporated into the gross carrying amount of the modified financial liability and are amortized over the remaining term of the modified financial liability. ​ vi. Offsetting of financial assets and liabilities ​ Financial assets and liabilities are offset, and the net amount is recognized in the consolidated statement of financial position, when there is a legally enforceable right to offset recognized amounts and management intends to settle them on a net basis or to realize the asset and settle the liability simultaneously. Income and expenses are presented on a net basis only when permitted under IFRS, or for gains and losses arising from a group of similar transactions such as Grupo Aval’s trading activity. ​ vii. Fair value measurement ​ “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 in the principal or, in its absence, the most advantageous market to which Grupo Aval has access at that date. ​ Grupo Aval measures the fair value of an instrument using the quoted price in an active market for that instrument. A market is regarded as active if transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. ​ If there is no quoted price in an active market, Grupo Aval uses valuation techniques that maximize the use of relevant observable inputs and minimize the use of unobservable inputs. The chosen valuation technique incorporates all of the factors that market participants would take into account in pricing a transaction. ​ The best evidence of the fair value of a financial instrument on initial recognition is normally the transaction price – i.e. the fair value of the consideration given or received. If Grupo Aval determines that the fair value on initial recognition differs from the transaction price and the fair value is evidenced neither by a quoted price in an active market for an identical asset or liability nor based on a valuation technique for which any unobservable inputs are deemed to be insignificant in relation to the measurement, then the financial instrument is initially measured at fair value, adjusted to defer the difference between the fair value on initial recognition and the transaction price. Subsequently, that difference is recognized in the Consolidated Statement of Income on an appropriate basis over the life of the instrument but no later than when the valuation is wholly supported by observable market data or the transaction is closed out. ​ Portfolios of financial assets and financial liabilities that are exposed to market risk and credit risk, managed by Grupo Aval on the basis of the net exposure to either market or credit risk are measured on the basis of a price that would be received to sell a net long position (or paid to transfer a net short position) for the particular risk exposure. Portfolio-level adjustments – e.g. bid-ask adjustment or credit risk adjustments that reflect the measurement on the basis of the net exposure – are allocated to the individual assets and liabilities on the basis of the relative risk adjustment of each of the individual instruments in the portfolio. ​ The fair value of a financial liability with a demand feature (e.g. a demand deposit) is no less than the amount payable on demand, discounted from the first date on which the amount could be required to be paid. ​ Grupo Aval recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period during which the change has occurred. See Note 5. ​ viii. Repurchase agreements and reverse repurchase agreements ​ Purchases of financial instruments under a non-optional resale agreement are measured at fair value and recognized as financial assets in the consolidated statement of financial position under interbank and overnight funds. ​ The excess of the purchase prices over the resale prices is recognized as interest income over the contractual term. ​ Sales of financial instruments under a non-optional repurchase agreement are measured at fair value and recognized as liabilities in the consolidated statement of financial position under Interbank borrowings, overnight funds and borrowings from banks and others. ​ The excess of the sales prices over the repurchase prices is recognized as interest expense over the contractual term. ​ Retained interests (i.e. the assets that collateralize the repurchase agreements) are primarily classified as fair value through OCI and measured at fair value. ​ ix. Impairment of financial assets Grupo Aval recognizes loss allowances for Expected Credit Losses – (“ECL”) on the following financial instruments that are not measured at FVTPL: ● Debt investment instruments; ● Loans and receivables; ● Financial guarantee contracts issued; ● Loan commitments issued, and ● Other accounts receivable No credit impairment loss is recognized on equity investments. ​ Grupo Aval measures loss allowances at an amount equal to lifetime ECL (Stage 2 and stage 3), except the following cases, for which they are measured as 12-month ECL (Stage 1): ● Debt investment securities that are determined to have low credit risk at the reporting date; and ● Other financial instruments (other than loans and lease receivables) on which credit risk has not increased significantly – (“SICR”) since their initial recognition. ​ Grupo Aval considers a financial asset is classified as a low credit risk asset if the issuer is related to an investment grade credit rating. ​ 12-month ECL is the portion of ECL that results from default events on a financial instrument that are possible within the 12 months after the reporting date. ​ See the detail of the requirement actions as result of Covid-19 in note 1.1 “Other events” ​ Measurement of ECL ​ Measurement of ECL is described in Note 4(4.1.5 Amounts arising from ECL). ​ Modified Financial Assets ​ If the terms of a financial asset are renegotiated or modified or an existing financial asset is replaced with a new one due to financial distress of the borrower, an assessment is made of whether the financial asset should be derecognized (see (iv)) and ECL are measured as follows: ● If the restructuring is not expected to result in derecognition of the existing asset, then the expected cash flows arising from the modified financial asset are included in calculating the cash shortfalls from the existing asset (see Note 4(4.1.1)). ● If the restructuring is expected to result in derecognition of the existing asset, then the expected fair value of the new asset is treated as the final cash flow from the existing financial asset at the time of its derecognition. This amount is included in calculating the cash shortfalls from the existing financial asset that are discounted from the expected date of derecognition to the reporting date using the original effective interest rate of the existing financial asset. ​ Credit-impaired financial assets ​ At each reporting date, Grupo Aval assesses whether financial assets carried at amortized cost and at FVOCI are credit-impaired. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. ​ Evidence that a financial asset is credit-impaired includes the following observable data: ● Significant financial difficulty of the borrower or issuer; ● A breach of contract such as a default or past due event; ● The restructuring of a loan or advance by Grupo Aval on terms that Grupo Aval’ entities would not consider otherwise; ● It is becoming probable that the borrower will enter bankruptcy or other financial reorganization; or ● The disappearance of an active market for a security because of financial difficulties. A loan that has been renegotiated due to a deterioration in the borrower’s condition is usually considered to be credit-impaired unless there is evidence that the risk of not receiving contractual cash flows has decreased significantly and there are no other indicators of impairment. In addition, a loan different to mortgage that is overdue for 90 days or more is considered impaired. In making an assessment of whether an investment in sovereign debt is credit-impaired, Grupo Aval considers the following factors. ● The market’s assessment of creditworthiness as reflected in the bond yields. ● The rating agencies’ assessments of creditworthiness. ● The country’s ability to access the capital markets for new debt issuance. ● The probability of debt being restructured, resulting in holders suffering losses through voluntary or mandatory debt forgiveness; and ● The international support mechanisms in place to provide the necessary support as ‘lender of last resort’ to that country, as well as the intention, reflected in public statements, of governments and agencies to use those mechanisms. This includes an assessment of the depth of those mechanisms and, irrespective of the political intent, whether there is the capacity to fulfil the required criteria. See the detail of the requirement actions as result of Covid-19 in note 1.1 “Other events” ​ x. Presentation of allowance for ECL in the statement of financial position Loss allowances for ECL are presented in the statement of financial position and the impact is showed in the statement of income line “ as follows: ● Financial assets measured at amortized cost: as a deduction from the gross carrying amount of the assets; ● Loan commitments and financial guarantee contracts: generally presented as provisions; ● Where a financial instrument includes both a drawn and an undrawn component, and Grupo Aval cannot identify the ECL on the loan commitment component separately from those on the drawn component: Grupo Aval presents a combined loss allowance for both components. The combined amount is presented as a deduction from the gross carrying amount of the drawn component. Any excess of the loss allowance over the gross amount of the drawn component is presented as a provision; and ● Debt instruments measured at FVOCI: no loss allowance is recognized in the statement of financial position because the carrying amount of these assets is their fair value. However, the ECL is disclosed and is recognized as part of the net change recognized in the fair value reserve under other comprehensive income. xi. Write-offs Loans and debt securities are written off (either partially or in full) when there is no prospect of recovery. This is generally the case when Grupo Aval determines that the borrower does not have assets or sources of income that could generate sufficient cash flows to repay the amounts subject to be written-off. Recoveries of amounts previously written off are included in “recovery of charged off financial assets” in the Consolidated Statement of Income. Financial assets that are written off could still be subject to enforcement activities in order to comply with Grupo Aval’s procedures for recovery of amounts due. The contractual amount outstanding on the financial assets that were written off during the reporting period are disclosed in note 4.1.5 Amounts arising from ECL; Loss Allowance reconciliation tables.
Description of accounting policy for restricted cash and cash equivalents [text block]	2.6 Cash and cash equivalents Cash and cash equivalents include cash, bank deposits, and other short-term investments with original maturities of three months or less from the date of their acquisition that are subject to an insignificant risk of changes in their fair value and are used by Grupo Aval in the management of its short-term commitments.
Description Of Accounting Policy For Trading Assets And Liabilities [Text Block]	2.7 Trading assets and liabilities ‘Trading assets and liabilities’ are those assets and liabilities that Grupo Aval mainly acquires or incurs for the purpose of selling or repurchasing in the near term or holds as part of a portfolio that is managed comprehensively for short-term profit or position taking. Trading assets and liabilities are initially recognized and subsequently measured at fair value in the Statement of Financial Position, with transaction costs recognized in Statement of Income. All changes in fair value are recognized as part of net trading income in Statement of Income.
Description of accounting policy for derivative financial instruments and hedging [text block]	2.8 Derivatives a) Derivatives and hedge accounting A derivative is a financial instrument for which value changes respond to changes in one or more variables denominated as “underlying” (e.g. a specific interest rate, the price of a financial instrument, a listed commodity, a foreign currency exchange rate, etc.). A derivative requires no initial net investment or an initial net investment that is smaller than would be required for other types of contracts that would be expected to have a similar response to changes in market factors. Grupo Aval trades in financial markets, forward contracts, future contracts, swaps and options that fulfil the definition of a derivative. Financial assets and liabilities arising from transactions with derivatives are generally not offset in the consolidated statement of financial position. However, when there is a legal and exercisable right to offset the recognized values and Grupo Aval intends to settle them on a net basis or to realize the assets and settle the liability simultaneously, derivatives are presented as net values in the consolidated statement of financial position. Derivative transactions are initially recognized at fair value. Subsequent changes in the fair value are recognized in profit or loss, unless the derivative instrument is designated as a hedging instrument and, in this case, the accounting criteria will depend on the nature of the hedged item, as described below. At the beginning of the hedging transaction, Grupo Aval formally documents the existing relationship between the hedging instrument and the hedged item, including the risk management objective and strategy in undertaking the hedging relationship. It also documents its assessment, both initially as well as on a recurring basis, of whether the hedging relationship is highly effective in offsetting the changes in fair value or cash flows of the hedged items. The applicable policy for hedging and embedded derivatives is described below: (i) For fair value hedge of assets or liabilities and firm commitments, changes in the fair value of the derivative instrument are recognized in profit or loss, as well as any other change in the fair value of the asset, liability or firm commitment attributable to the hedge risk, (ii) For cash flow hedge of a particular risk associated with a recognized asset or liability or a projected highly probable transaction, the effective portion of changes in the fair value of the derivative is recognized in other comprehensive income. The gain or loss relating to the portion that is not effective for hedging or that does not relate to the hedged risk is immediately recognized in profit or loss. The values accumulated in other comprehensive income are transferred to profit or loss in the same period in which the hedged item is recognized in profit or loss; and (iii) Hedging of net investments in a foreign operation is recognized similarly to cash flow hedging: the effective portion of changes in fair value of the hedging instrument is recognized in other comprehensive income, and the ineffective portion of the changes in fair value of the derivative is recognized in profit or loss. The hedging instrument’s gains or losses accumulated in equity will be recognized in profit or loss when the net investment in foreign operations is sold or partially disposed of . b) Embedded derivatives Derivatives may be embedded in another contractual arrangement (a host contract). Grupo Aval accounts for an embedded derivative separately from the host contract when: ● The host contract is not a financial asset in the scope of IFRS 9; ● The host contract is not itself carried at FVTPL; ● The terms of the embedded derivative would meet the definition of a derivative if they were contained in a separate contract; and ● The economic characteristics and risks of the embedded derivative are not closely related to the economic characteristics and risks of the host contract. Separated embedded derivatives are measured at fair value, with all changes in fair value recognized in profit or loss unless they form part of a qualifying cash flow or net investment hedging relationship. Separated embedded derivatives are presented in the statement of financial position together with the host contract.
Description of accounting policy for loans and receivables [text block]	2.9 Loans The ‘Loans’ line item in the statement of financial position include: ● Loans measured at amortized cost (see 2.5(ii)); they are initially measured at fair value plus incremental direct transaction costs, and subsequently at their amortized cost using the effective interest method; ● Financial lease receivables measured at amortized cost (see 2.5(ii)). When Grupo Aval purchases a financial asset and simultaneously enters into an agreement to resell the asset (or a substantially similar asset) at a fixed price on a future date (reverse repo or stock borrowing), the arrangement is accounted for as a loan, and the underlying asset is not recognized in Grupo Aval’s financial statements. The effective interest rate method is a method of calculating the amortized cost of a financial asset and allocating the interest income or expense over the relevant period. The effective interest rate is the rate that discounts future cash payments or receipts (without consideration of future credit losses, over the expected life of the financial instrument) to the net carrying amount of the financial asset at initial recognition. In the process of calculating the effective interest rate, Grupo Aval estimates the cash flows considering the contractual terms including prepayment expectations of the financial instrument for portfolios with high prepayment levels, except for future credit losses and considering the initial fair value plus transaction costs and premiums granted, minus commissions and discounts received which form integral part of the effective rate.
Description of accounting policy for investment in associates and joint ventures [text block]	2.10 Investment securities The ‘investment securities’ line in the statement of financial position includes: ● Debt investment securities measured at amortized cost (see 2.6(ii)); These are initially measured at fair value plus incremental direct transaction costs, and subsequently at their amortized cost using the effective interest method; ● Debt and equity investment securities mandatorily measured at FVTPL (see 2.6(ii)); These are at fair value with changes recognized immediately in profit or loss; ● Debt securities measured at FVOCI; and ● Equity investment securities designated as at FVOCI. For debt investment securities measured at FVOCI, gains and losses are recognized in OCI, except for the following, which are recognized in profit or loss in the same manner as for financial assets measured at amortized cost: ● Interest revenue using the effective interest method; ● ECL impairments and reversals of impairments; and ● Foreign exchange gains and losses. When a debt security measured at FVOCI is derecognized, the cumulative gain or loss previously recognized in OCI is reclassified from equity and recognized as profit or loss in the Consolidated Statement of Income under “other income net gain on sale of debt and equity securities”. Grupo Aval elects to present changes in the fair value of certain investments in equity instruments that are not held for trading in OCI. The election is made on an instrument-by-instrument basis on initial recognition and is irrevocable. Gains and losses on such equity instruments are never reclassified to profit or loss and no impairment is recognized in profit or loss. Cumulative gains and losses recognized in OCI are transferred to retained earnings upon disposal of an investment. Dividends are recognized in profit or loss unless they clearly represent a recovery of part of the cost of the investment, in which case they are recognized in OCI. After initial recognition, net gains and losses resulting from changes in fair value for financial assets classified and measured at fair value, are presented either (i) in the income statement in the account “net trading income - trading investment securities” for financial assets at FVTPL or (ii) in OCI for financial instruments at FVOCI, in accordance with note 2.5 ii) above. In turn, after their initial recognition, financial assets classified at amortized cost are adjusted to reflect interest accrued at the effective interest rate method, less payments received from borrowers. See detail of effective interest rate method in note 2.9 Loans Income from dividends from financial assets in equity instruments at FVOCI is recognized in income in the account of “other income dividends” when the right to receive payment is established, regardless of the decision that has been made to record the variations in fair value in results or OCI.
Description of accounting policy for financial liabilities [text block]	2.11 Financial liabilities A financial liability is any contractual liability in which Grupo Aval commits to deliver cash or other financial asset to another entity or person, or to exchange financial assets or financial liabilities under potentially unfavorable conditions for Grupo Aval, or a contract which will be terminated or could be settled using equity instruments owned by the entity. Financial liabilities are initially recognized based on their fair value, which is usually equal to the transaction value adjusted by directly attributable costs. Subsequently, such financial liabilities are measured at their amortized cost according to the effective interest rate method determined at initial recognition and recognized in profit or loss. Financial liabilities are only derecognized from the consolidated statement of financial position when the obligations are extinguished, that is, when the obligations are discharged, cancelled, or expire.
Description Of Accounting Policy For Financial Guarantees Explanatory [text block]	2.12 Financial guarantees Financial guarantees are those contracts requiring that the issuer carries out specific payments to reimburse the creditor for losses incurred when a specific debtor defaults in its payment obligation, in accordance with the original or modified conditions, of a debt instrument; regardless of its legal form. Financial guarantees issued or commitments to provide a loan at a below-market interest rate are initially measured at fair value. Subsequently, they are measured as at the highest value between the amount initially recognized net of the loss allowance determined in accordance with IFRS 9 (see 2.5 (vii)) and the amount initially recognized less, when appropriate, the cumulative amount of income recognized in accordance with the principles of IFRS 15. As of the reporting date Grupo Aval has no loan commitments that are measured at FVTPL. Credit risk impairment losses established over financial guarantee contracts under IFRS 9, are recognized as liabilities under “Provisions – other provisions” and recognized in profit or loss under “other expenses”, see note 2.5 ix “Impairment of financial assets in the statement of financial position”.
Description of accounting policy for non-current assets or disposal groups classified as held for sale and discontinued operations [text block]	2.13 Non-current assets held for sale Foreclosed assets and non-current assets held for sale, which Grupo Aval intends to sell in a period of less than one year, and it is considered highly probable that their value will be recovered primarily through sale rather than through continuing use, are recognized as "non-current assets held for sale". These assets are measured at the lower of their carrying value at the time of transfer and fair value, less estimated disposal costs.
Description of accounting policy for property, plant and equipment [text block]	2.14 Property, plant and equipment for own use Property, plant and equipment include the assets, owned or under financial leases held by Grupo Aval for current or future use for more than one period. They are recognized in the consolidated statement of financial position at their acquisition or construction cost, less the corresponding accumulated depreciation and, if applicable, the estimated impairment losses resulting from comparing the carrying amount of each asset with its recoverable value. Depreciation is calculated by applying the straight-line method over the acquisition cost of the assets (except for the bearer plants, which are depreciated based on production units), less any residual value; land is not depreciated. Depreciation is estimated on a straight-line basis during the estimated useful life of the asset less their residual value. The annual depreciation rates for each type of assets are: ​ ​ ​ ​ Asset Useful Life Own use buildings According to appraisals Equipment, furniture and accessories From 3 to 10 years Machinery and equipment (*) From 5 to 25 years Computer equipment From 3 to 12 years Vehicles From 5 to 10 years Bearer plants From 25 to 35 years (*) ​ Conservation and maintenance expense is recognized when incurred as “Administrative Expense”. At each reporting date, the Group analyzes whether there are signs, that an asset may be impaired for such purposes, develops what is established in policy 2.21 "Impairment of non-financial assets". A bearer plant is a live plant that meets the following requirements: a) It is used for the manufacturing or supply of agricultural products; b) It is expected to produce for more than one period; and c) It has a remote probability of being sold as an agricultural product, except for irregular sales related to thinning and trimming. Bearer plants under the set-up and growing phase are subject to a biological transformation which is reflected through cost accumulation until they reach their maturity level. In the case of the African oil palm, maturity is reached in the second year, while maturity for rubber plants is reached in the seventh year. After reaching their maturity, bearer plants are considered developed and the future economic benefits arise from the sale of the fruit produced during the useful life of the plant. Bearer plants are measured at their cost less accumulated depreciation and any impairment losses. The useful life is equal to the plants´ production periods. The useful life of the rubber plant is 35 years while the useful life of the African oil palm is 25 years. The depreciation method used is the estimated production units as it most accurately reflects the usage of the assets If the bearer plant is sold for timber at the end of the useful life the value received is considered the residual value of the asset.
Description of accounting policy for investment property [text block]	2.15 Investment properties Land and buildings, considered in whole or in part, that are held to earn rental income or for capital appreciation, rather than for own use or sale in the ordinary course of business. Investment properties are recognized initially at cost, including all costs associated with the transaction, and subsequently measured at fair value, with changes in fair value recognized in profit or loss.
Description of accounting policy for leases [text block]	2.16 Leases Lessee accounting At inception of a contract, Grupo Aval assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Group uses the definition of a lease in IFRS 16. ​ Grupo Aval recognizes a right-of-use asset and a lease liability at the lease commencement date. ​ The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove any improvements made. ​ The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the end of the lease term. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability. ​ The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group’s incremental borrowing rate. Generally, the Group uses its incremental borrowing rate as the discount rate. ​ Grupo Aval determines its incremental borrowing rate by analyzing its borrowings from various external sources and makes certain adjustments to reflect the terms of the lease and type of asset leased. ​ When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset; or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. ​ Grupo Aval presents right-of-use assets in ‘Tangible assets’ and lease liabilities in ‘Borrowings from banks and others’ in the statement of financial position. ​ ​ Short-term leases and leases of low-value assets ​ Grupo Aval has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases. The Grupo Aval recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term. ​ ​ Lessor accounting ​ When Grupo Aval acts as a lessor, it determines at lease inception whether the lease is a finance lease or an operating lease. To classify each lease, the Group makes an overall assessment of whether the lease transfers substantially all of the risks and rewards incidental to ownership of the underlying asset. If this is the case, then the lease is a finance lease; if not, then it is an operating lease. As part of this assessment, the Group considers certain indicators such as whether the lease is for a major part of the economic life of the asset. Lease contracts classified as financial leases are included in the consolidated statement of financial position as “Loans” and are recognized in the same way as other loans, as explained in note 2.11. ​ ​
Description of accounting policy for biological assets [text block]	2.17 Biological assets Biological assets; are measured at fair value less disposal cost, both at the time of initial recognition and at the end of reporting period, except for biological assets for which fair value cannot be measured reliably; in which case they are measured at cost less accumulated depreciation and impairment loss. Gains and losses arising from the initial and subsequent fair value measurement of the agricultural products are included in the Consolidated Statement of Income. Costs incurred in the agricultural production process are also recognized directly in the Consolidated Statement of Income. The fair value of biological assets is determined using valuations performed by experienced internal professionals, using discounted cash flow models. The expected cash flows of the crop’s total life are determined by using the market price of the agricultural product currently in effect and the estimated productive life of plants, net of maintenance and harvest costs and of any other costs required for plant maintenance during the production period. The productive life of plants is estimated considering the age, location and type of product. The fair value of the biological assets is dependent on current market prices for each product.
Description of accounting policy for business combinations and goodwill [text block]	2.18 Business combinations and goodwill Business combinations are accounted for using the “acquisition method” when control is transferred to the controlling entity. The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired. If non-controlling interests arise during the acquisition of control of the entity, such non-controlling interests are recognized at either fair value. Goodwill is measured as the excess of the aggregate of consideration transferred, over the amount of any interest previously acquired and the net of identifiable assets acquired and liabilities assumed at acquisition date. Goodwill acquired in a business combination is assigned to each of the groups of cash-generating units from which benefit are expected as a result of the acquisition. Goodwill is not subsequently amortized; however, it is subject to an annual impairment assessment in relation to the cash-generating unit to which it has been assigned and, from which benefits are expected deriving from the synergies of business combinations. A loss due to impairment recognized on Goodwill cannot be reversed in subsequent periods.
Description of accounting policy for intangible assets other than goodwill [text block]	2.19 Other intangible assets ​ Other intangible assets mainly comprise software and licenses, which are initially measured at the cost of acquisition or cost of development. Costs incurred during the research phase are expensed as incurred. ​ Development expenses which are directly attributable to design and performance tests of software and identifiable, unique and controlled by Grupo Aval are recognized as intangible assets, if following conditions are met: ● Technically, it is possible to complete the intangible asset production, so it can be available for use; ● Management intends to complete the corresponding intangible asset for use; ● Management has the capacity of using the intangible asset; ● It is probable that future economic benefits that are attributable to the asset will flow to the entity; ● There is availability of adequate technical or financial resources or other type, for completion and usage of the intangible asset; and ● Costs attributable to the intangible asset during its development phase can be estimated and measured in a reliable manner. Costs that are directly attributable and capitalized as part of intangible assets include personnel expense directly related to developing such intangibles and overhead expenses that can be capitalized. Expenses that do not satisfy these criteria are recognized as incurred expenses. Disbursements over intangible assets are initially recognized as expenses of the period and they are not be subsequently recognized as intangible assets. Subsequent to their initial recognition, these assets are measured at cost less amortization, which is carried out during their estimated useful lives as follows: amortization is recognized on a straight-line basis, according to the estimated useful lives. The annual amortization rates for each type of assets are: ​ ​ ​ ​ ​ ​ ​ ​ Intangible Asset Useful Life Software and information technology applications From 1 to 20 years Licenses From 1 to 15 years Trademarks Indefinite Customer-related assets From 1 to 10 years Intellectual property rights From 1 to 38 years Models, formulas, designs and prototypes 10 years Easements ​ From 20 to 50 years ​ At the end of each period, Grupo Aval analyzes if there is evidence based on each CGU (Cash Generating Unit), both external and internal, indicating that the intangible asset is impaired. Any loss due to subsequent impairment or reversal is recognized in the Consolidated Statement of Income; such impairment is determined by the excess of the carrying amount over the recoverable value.
Description of accounting policy for service concession arrangements [text block]	2.20 Concession arrangements rights ​ Concession contracts, are those in virtue of which certain subsidiaries of Grupo Aval make a commitment with the Governments in the countries in where we operate for the construction or maintenance of infrastructure, for a period of time during which, said entities receive the revenue derived from the contract, either through direct payments from the Government, through tolls or other types of fees charged to the end users of the project, which, are recognized as financial assets or intangible assets. ​ A financial asset is recognized when pursuant to the contractual conditions, there is an entitlement to an unconditional contractual right of receiving cash or other financial assets from the grantor or from the Government, due to construction services or when the Government guarantees minimum income from tolls or fees charged to the users of the concession work during the term of the concession agreement. ​ An intangible asset is recognized if in the concession contract does not include an unconditional right for the concessionaire to receive cash and, on the contrary, its revenue depends on the right it has for the use of the infrastructure under concession. In some cases, contracts can contain both financial and intangible assets. ​ Concession arrangements are recognized as follows: ​ (a) During the construction stage, all estimated income for construction services as well as the costs associated to the construction are recognized in the Consolidated Statement of Income based on the stage of completion of the work performed. In the event that there is an expected loss, this is recognized as an expense immediately. ​ (b) If all or part of the concession arrangement is classified as a financial asset, it is recognized in accordance with the accounting policy for financial assets as set out in note 2.5. ​ (c) If all or part of the concession contract is classified as an intangible asset, the revenues are accumulated as intangible assets during the construction phase of the project, assets and are amortized over the term of the arrangement in a manner that reflects the pattern in which the concession asset’s economic benefits are consumed by the entity, from the moment the asset enters into service.
Description of accounting policy for impairment of non-financial assets [text block]	2.21 Impairment of non-financial assets At each reporting date, Grupo Aval reviews the carrying amounts of its non-financial assets (other than investment properties and deferred tax assets) to determine whether there is any indication of impairment. If any such indication exists, then the asset’s recoverable amount is estimated. Goodwill is tested annually for impairment. For impairment testing, assets are grouped together into the smallest group of assets that generates cash inflows from continuing use that is largely independent of the cash inflows of other assets or Cash Generating Units (CGU). Goodwill arising from a business combination is allocated to CGUs or groups of CGUs that are expected to benefit from the synergies of the combination. The “recoverable amount” of an asset or CGU is the greater of its value in use and its fair value less costs to sell. “Value in use” is based on the estimated future cash flows, discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or cash generating units “CGU”. An impairment loss is recognized if the carrying amount of an asset or CGU exceeds its recoverable amount. Impairment losses are recognized in profit or loss. They are allocated first to reduce the carrying amount of any goodwill allocated to the CGU, and then to reduce the carrying amounts of the other assets in the CGU on a pro rata basis. An impairment loss of goodwill cannot be reversed. For other assets, an impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.
Description of accounting policy for employee benefits [text block]	2.22 Employee Benefits ​ Grupo Aval´s entities provide the following benefits to employees in exchange of services rendered to the Group: ​ a) Short-term employee benefits Pursuant to Colombian and other countries labor rules, such benefits are comprised of salaries, premiums, vacations, severance payments and payroll tax contributions to the local Government designated agencies which are paid within 12 months following the end of the reporting period. Such benefits are accumulated on an accrual basis and recognized in profit or loss. ​ b) Post-employment benefits (defined benefit plans) Grupo Aval pays to its employees certain benefits when they retire or upon completion of their employment period, other than indemnities. These benefits include retirement pensions which are directly assumed by Grupo Aval’s entities, pending severance payments to employees belonging to the labor regime prior to Law 50 1990 in Colombia, and certain extra-legal benefits or benefits agreed in collective bargaining agreements. ​ Post-employment benefits liabilities are determined based on the present value of estimated future payments, calculated based on actuarial assessments using the projected unit of credit method, and applying actuarial assumptions about mortality rate, increase of salaries and personnel turnover, and interest rates determined with reference to bond market returns of local Government’ bonds or high-quality business liabilities in effect at the reporting date. Under the projected unit of credit method, future benefits to be paid to employees are assigned to each accounting period in which the employee renders the service. Therefore, the corresponding expense due to these benefits recognized in profit or loss of Grupo Aval includes the present service cost assigned in the actuarial calculation plus the financial cost of calculated liabilities. Changes in liabilities due to changes in actuarial assumptions are recognized in Other Comprehensive Income. ​ Changes in actuarial liabilities due to changes in employment benefits granted to employees that have a retroactive effect are recognized as an expense in the earlier of the following dates: ● When a modification of the granted employment benefits takes place, or ● When provisions for restructuring costs are recognized by a subsidiary. c) Other long-term employee benefits Long term benefits are different from employee short-term benefits, post-employment benefits and termination benefits. In accordance with the collective bargaining agreements and regulations of each company of Grupo Aval, such benefits are mainly related to seniority bonuses. Long-term liabilities for employee benefits are determined in the same manner as post-employment benefits described in item (b) above; the only difference is that the changes in the actuarial liability due to changes in the actuarial assumptions are recognized in profit or loss. d) Termination benefits These benefits are payments which must be made by Grupo Aval´s entities derived from their taking the unilateral decision of terminating and employee´s labor contract or from and employee´s decision to accept benefits offered by an entity in exchange for terminating the employment contract, such payments correspond to severances for dismissal or redundancy and other benefits that entities unilaterally decide to grant to their employees under such circumstances. Termination benefits are recognized as a liability and in profit or loss at the earlier of the following dates: ● When Grupo Aval´s entities formally inform to the employee about its decision of dismissal; or ● When provisions for restructuring costs are recognized by a subsidiary.
Description of accounting policy for income tax [text block]	2.23 Income taxes Income tax expense includes both current and deferred tax. Tax expense is recognized in profit or loss except for items recognized in Other Comprehensive Income or directly in equity. Current income tax expense is calculated based on the tax laws in force (enacted or substantively enacted) in each of the countries in which we operate as of the reporting date of the consolidated financial statements is subject to the income tax. Management of each subsidiary of Grupo Aval periodically assesses tax return positions with respect to situations where the applicable tax regulation is subject to interpretation and establishes provisions, when appropriate, on the basis of amounts expected to be paid to tax authorities. Deferred taxes are recognized with respect to temporary differences arising between carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for tax purposes. Deferred taxes are not recognized for: (i) temporary differences on the initial recognition of goodwill; (ii) temporary differences on the initial recognition of an asset or liability in a transaction that is not a business combination and that affects neither the accounting nor the taxable profit or loss and (iii) temporary differences related to investments in subsidiaries to the extent that it is probable that they will not reverse in the foreseeable future. Deferred taxes are measured using the tax rates that are expected to be applied to the temporary differences upon reversal, using enacted tax rates or substantively enacted at the reporting date. Deferred taxes assets are only recognized to the extent it is probable that future taxable income is expected to be available to offset temporary differences. Deferred tax liabilities arise from taxable temporary differences, except for the deferred tax liabilities on investments in subsidiaries, when the opportunity of reversal of temporary differences is controlled by Grupo Aval and it is not expected to be reversed in the near future. Generally, Grupo Aval has the ability to control the temporary differences of investments in associates. Current taxes are offset only when the entity has a legally enforceable right to offset and the entity intends to either settle on a net basis or to realize the asset and settle the liability simultaneously. Deferred taxes are offset when the entity has a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred tax assets and liabilities are related to income taxes levied by the same tax authority over the same taxable entity or over different entities but these entities have an intention to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realized simultaneously, for each period in which these differences reverse. In determining the amount of current and deferred taxes, Grupo Aval considers the impact of uncertain tax exposures on current tax liabilities, including whether additional taxes and interest may be due. This assessment relies on estimates and assumptions and may involve a series of judgments about future events. New information may become available that causes Grupo Aval to change its judgment regarding the adequacy of existing tax liabilities; such changes to tax liabilities would impact tax expense in the period in which such a determination is made.
Description of accounting policy for borrowing costs [text block]	2.24 Capitalization of borrowing costs Borrowing costs which are directly attributable to the acquisition, construction or production of a qualifying asset which requires a substantial period of time to get ready for its intended use are part of the cost of the asset. Other borrowing costs are recognized as expenses. ​ Grupo Aval begins capitalizing borrowing costs as part of the cost of a qualifying asset on the commencement date. This is the date when the entity first meets all of the following conditions: ​ (a) it incurs expenditures for the asset; (b) it incurs borrowing costs; and (c) it undertakes activities that are necessary to prepare the asset for its intended use or sale.
Description of accounting policy for provisions [text block]	2.25 Provisions Provisions for environmental dismantling and recovery, restructuring costs and legal claims are recognized when Grupo Aval has a present legal or assumed obligation as a result of past events, and it is probable that an outflow of economic benefits will be required to settle the obligation. Restructuring provisions include penalties due to cancelation of leases. Provisions are measured at the present value of outflows expected to be necessary to settle the obligation, using a discount rate before taxes, reflecting the assessments of the time value of money of the current market as well as the specific risks of the obligation. The subsequent increase of the provision due to the unwinding of the discount rate is recognized as “financial expense”.
Disclosure Of Accounting Policy For Nonvoting Rights Of Preferred Shares Explanatory [Text Block]	2.26 Non-voting rights of preferred shares Preferred shares represent partial ownership and do not provide shareholders with any of the voting rights of common shares. Grupo Aval has classified as an equity instrument all the non-voting preferred shares. See note 25 equity attributable to owners of the parent.
Description of accounting policy for recognition of revenue [text block]	2.27 Revenues ● Net interest income (i) Effective interest rate Interest income and expense are recognized in the Consolidated Statement of Income using the effective interest method. The ‘effective interest rate’ is the rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial instrument to: ● The gross carrying amount of the financial asset; or ● The amortized cost of the financial liability. When calculating the effective interest rate for financial instruments other than credit-impaired assets, Grupo Aval estimates future cash flows considering all contractual terms of the financial instrument, but not expected credit losses. For credit-impaired financial assets, a credit-adjusted effective interest rate is calculated using estimated future cash flows including expected credit losses. The calculation of the effective interest rate includes transaction costs and fees and points paid or received that are an integral part of the effective interest rate. Transaction costs include incremental costs that are directly attributable to the acquisition or issue of a financial asset or financial liability. (ii) Amortized cost and gross carrying amount The ‘amortized cost’ of a financial asset or financial liability is the amount at which the financial asset or financial liability is measured on initial recognition minus the principal repayments, plus or minus the cumulative amortization using the effective interest method of any difference between that initial amount and the maturity amount and, for financial assets, adjusted for any expected credit loss allowance. The ‘gross carrying amount’ of a financial asset is the amortized cost of a financial asset before adjusting for any expected credit loss allowance. (iii) Calculation of interest income and expense In calculating interest income and expense, the effective interest rate is applied to the gross carrying amount of the asset (when the asset is not credit-impaired) or to the amortized cost of the liability to calculate the interest income and expenses. However, for financial assets that have become credit-impaired subsequent to initial recognition, interest income is calculated by applying the effective interest rate to the amortized cost of the financial asset. If the asset is no longer credit-impaired, then the calculation of interest income reverts to the gross basis. For financial assets that were credit-impaired on initial recognition, interest income is calculated by applying the credit-adjusted effective interest rate to the amortized cost of the asset. The calculation of interest income does not revert to a gross basis, even if the credit risk of the asset improves. For information on when financial assets are credit-impaired, see note 2(2.5) (ix). (iv) Presentation Interest income and expense presented in the Consolidated Statement of Income include: ● Interest on financial assets and financial liabilities measured at amortized cost calculated on an effective interest basis, see note 2.27 (i); ● Interest on debt instruments measured at FVOCI calculated on an effective interest basis see note 2.27 (i); Interest income and expense on all trading assets and liabilities are considered to be incidental to Grupo Aval’s trading operations and are presented together with all other changes in the fair value of trading assets and liabilities in net trading income. Interest income and expense on other financial assets and financial liabilities mandatory at FVTPL are presented in “Net trading income” and financial assets in concessions arrangements rights at FVTPL under “Net income from financial instruments at fair value other that negotiable”. ● Net trading income ‘Net trading income’ comprises net gains or losses related to held for trading assets and liabilities, and includes all realized and unrealized fair value changes, interest, dividends and foreign exchange differences. ● Revenue from contracts with customers (other than interest income). Contract assets A contract asset is Grupo Aval’s right to consideration in exchange for goods or services that Grupo Aval has transferred to a customer when that right is conditional on something other than the passage of time (for example, invoicing or delivery of other elements of the contracts). Contract costs eligible for capitalization as incremental costs of obtaining a contract are recognized as a contract asset. Contract costs are capitalized when are incurred if Grupo Aval expects to recover those costs. Contract costs are amortized on a systematic basis consistent with the transfer of the services to the customer and the related revenues are recognized. Contract costs capitalized are impaired if the customer retires or if the asset’s carrying amount exceeds projected discounted cash flows relating to the contract. Contract liabilities Contract liabilities comprise Grupo Aval’s obligation to transfer goods or services to a customer for which Grupo Aval has received consideration from the end customer or the amount is due. Additionally, it includes deferred income relating to goods or services that will be delivered in the future, which are charged to a customer in advance but not yet due. Steps for revenue recognition Grupo Aval recognizes revenue from contracts with customers based on a five-step model as set out in IFRS 15: ● Step 1. Identify contract(s) with a customer: A contract is defined as an agreement between two or more parties that creates enforceable rights and obligations and sets out the criteria for every contract that must be met. Contracts can be written, oral or implied by an entity’s customary business practices. ● Step 2. Identify performance obligations in the contract: A performance obligation is a promise in a contract with a customer to transfer a good or service to the customer. ● Step 3. Determine the transaction price: The transaction price is the amount of consideration to which Grupo Aval expects to be entitled in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties. ● Step 4. Allocate the transaction price to the performance obligations in the contract: For a contract that has more than one performance obligation, Grupo Aval allocates the transaction price to each performance obligation in an amount that depicts the amount of consideration to which Grupo Aval expects to be entitled in exchange for satisfying each performance obligation. ● Step 5. Recognize revenue when (or as) Grupo Aval satisfies a performance obligation. Grupo Aval satisfies a performance obligation and recognizes revenue over time, if one of the following criteria is met: a) Grupo Aval´s performance does not create an asset with an alternate use to Grupo Aval, and Grupo Aval has as an enforceable right to payment for the performance completed to date. b) Grupo Aval´s performance creates or enhances an asset that the customer controls as the asset is created or enhanced. c) The customer simultaneously receives and consumes the benefits provided as Grupo Aval´s performs its obligation. For performance obligations where one of the above conditions are not met, revenue is recognized at the point in time at which the performance obligation is satisfied. When Grupo Aval satisfies a performance obligation by delivering the promised goods or services it creates a contract asset on the amount of consideration earned by the performance. Where the amount of consideration received from a customer exceeds the amount of revenue recognized this gives rise to a contract liability. Revenue is measured based on consideration specified in a contract with a customer and excludes amounts collected on behalf of third parties. Grupo Aval recognizes revenue when it transfers control over a good or service to a customer. Revenue is presented net of value added tax (VAT), rebates and discounts and after eliminating intra-group sales. Grupo Aval assesses its revenue arrangements to determine if it is acting as principal or agent. Revenue is recognized to the extent it is probable that the economic benefits will flow to Grupo Aval and the revenue and costs, if applicable, can be measured reliably. The following is a description of principal activities from which Grupo Aval generates revenue from contracts with customers: (i) Banking (Financial Services) Grupo Aval often enter into contracts that cover a number of different services. Such contracts might contain components within, and components outside, the scope of IFRS 15. Therefore, Grupo Aval only applies the IFRS 15 guidance where it has contracts that are all or partly outside the scope of IFRS 9. The main revenue streams earned by the banks from contracts with customers are the following: ​ ● Commissions Banks receive bancassurance commissions for introducing new clients to third party insurers, where the bank does not underwrite the insurance policy itself. These commissions are usually paid periodically (for example, monthly) to banks based on the volume of new policies (and/or renewal of existing policies) originating from clients introduced by the bank. The transaction price might include an element of consideration that is variable or contingent on the outcome of future events, such as policy cancellations, which is estimated and included in the transaction price based on the most likely amount only when it is highly probable that the resolution of the uncertainty will not result in a significant reversal of revenue. Performance obligations are fulfilled over time, taking into account that customers (insurers) receive benefits as time progresses. Where the commission calculation is made on a monthly basis or in a shorter period, the total amount of the commission is recognized in the results when its determination is made. If the settlement of commissions is defined in periods longer than a monthly basis, the expected income to recognize revenues is estimated as time progresses. Loan commitment fees are within the scope of IFRS 15 when it is unlikely that a specific lending arrangement will be entered into and the loan commitment is not measured at FVTPL. Loan syndication fees received by a bank that arranges a loan and retains no part of the loan package for itself (or retains a part at the same Effective Interest Rate “EIR” for comparable risk as other participants) are within the scope of IFRS 15. Income from performance obligations to provide such services, which are met at a point in time, are recognized when the particular event defined in the contracts occurs (e.g., approval of the syndicated loan). The obligations met over time are recognized during the period of the commitment; If income is received in advance, it is deferred over the period of the commitment. If income is received upon expiration, it is estimated periodically. ​ ​ ● Credit cards: Interchange fees, Annual-quarterly-monthly fees, Loyalty programs There are contracts that create enforceable rights and obligations between the Bank and the cardholders or merchants under which the bank will provide services, sometimes in exchange for annual and other fees. The following are some of the services that might exist in a contract with a cardholder: ● Issuance of loyalty points (which are options to acquire goods/services for free or at a discount in the future), usually based on the monetary volume of card transactions; ● Payment processing service; ● Insurance where the bank is not the insurer; ● Fraud protection; and ● Processing of certain transactions, such as purchases in a foreign currency and Advances. The transaction price is allocated to each performance obligation based on the relative stand-alone selling prices of the goods or services being provided to the customer. The allocation of the transaction price to each of the separate performance obligations will not necessarily be required where there is more than one performance obligation and the performance obligations all satisfied at the same time or evenly over the period. ​ Performance obligations are fulfilled over time, taking into account that customers receive benefits as time goes on. Given that the entity's efforts or resources are expended evenly throughout the performance period, income is recognized on a linear basis during the period defined under the credit card conditions. The costs of plastic or security elements are capitalized as contract signing costs. In connection with Grupo Aval the credit and debit card processing fee, customers receive benefits every time they make purchases. In this context, income is recognized periodically (daily or monthly) on the basis of the amounts traded. Income that would be deferred by the valuation of the points granted to the cardholders will be extracted from the total amount of commissions recorded periodically. See section (vi) Customer loyalty program below. ​ ​ ● Savings and checking accounts: Account and transaction fees Savings and checking accounts contracts usually allow customers access to a variety of services, including wire transfer processing, ATM use for cash withdrawals, issuance of debit cards, and account statements; they might also include other benefits. Fees are charged on a periodic basis and give the customer access to banking services and additional benefits. Performance obligations are fulfilled over time, taking into account that customers receive benefits as time progresses. As a result, banks recognize fees from providing services in the accounting period in which the services are rendered. ​ ● Investment banking: Underwriting fees and Advisory fees Advisory contracts with customers are not standardized. These contracts might differ between customers, and they often include variable consideration, including contingent fees, that are only payable upon meeting agreed milestones. ​ Income from performance obligations to provide such services, which are met at a point in time, are recognized when the particular event defined in the contracts occurs. The obligations met over time are recognized considering method of milestones achieved (when only one milestone that considers the delivery of results, income is recognized at a single moment when the final delivery is made.) ​ (ii) Asset management Revenues of asset portfolios management correspond to fees which arise from the rendering of management and advisory services and usually are measured based on performance and profit of asset portfolios of asset portfolios, which are recognized based on amounts calculated under the formulas established by the contracts when such amount is no longer subject to adjustments resulting from future events. If the fee expected is variable, the variable consideration included in the transaction price is limited to the amount for which it is highly probable that a significant reversal of the amount of cumulative revenue recognized will not occur when the uncertainty is resolved. In the estimation, Grupo Aval considers both the likelihood and the magnitude of the revenue reversal. Factors that could increase the likelihood or the magnitude of a revenue reversal include, but are not limited to, (i) the amount of consideration is highly susceptible to factors outside the entity’s influence, (ii) the uncertainty about the amount of consideration is not expected to be resolved for a long period of time, and (iii) the contract has a large number and broad range of possible consideration amounts. Fees are often based on net assets under management or returns generated by the underlying investments held by the funds subject to certain thresholds. The contractual measurement period for performance fees of fund managers is often a month, quarter or year, and in some rare cases longer. In some cases, the fees will be constrained until the contractual measurement period is completed. The Group assess if there is a portion (a minimum amount) of the variable consideration that should be recognized prior to the end of the contractual measurement period. The full amount of the fee will likely be recognized as of the end of the contractual measurement period when the asset manager becomes certain of the amount. In certain cases, the full amount of the fee will be recognized upon redemption when is no longer subject to reversal. (iii) Construction and operation services (Concessions) In concession arrangements, Grupo Aval determines that its performance obligations (construction, operation and maintenance) are satisfied over time and measures progress toward completion to determine the timing of revenue recognition using a method that depicts the transfer of the goods or services to the customer. Grupo Aval considers the nature of the product or services provided and the terms of the contract, such as termination rights, the rights to demand or retain payments, and the legal title to work in process in determining the best input or output method for measuring progress toward satisfaction of the performance obligation. Estimations of revenues, costs or progress toward completion are revised if circumstances change. Any resulting increases or decreases in estimated revenues or costs are reflected in profit or loss in the period in which the circumstances that give rise to the revision become known by management. (iv) Power and utilities Contracts between a customer and a public utility company establish the rates and terms of service for the purchase, delivery, and sale of electricity or gas. Grupo Aval determines that its obligation is represented in a single performance obligation which is to sell electricity or gas, and it is satisfied over time (over the term of the agreement) through a series of distinct goods or services that are substantially the same and have the same pattern of transfer to the customer. Some contracts include multiple deliverables, such as the installation of fixtures or repairs, which are accounted as separate performance obligations. The transaction price is allocated to each performance obligation based on the stand-alone selling prices (regulated rates). If contracts include the installation of fixtures, the associated revenue is recognized at the point in time when goods are installed, the ownership has been transferred and the customer has accepted the goods. (v) Logistic activities Grupo Aval´s transport and logistics companies offer multiple products or services to their customers as part of a single agreement. Separate performance obligations are identified in an agreement based on the terms of the contract and Grupo Aval's usual business practices. Revenue recognition criteria generally applies separately to each performance obligation. In certain circumstances, it may be necessary to separate a transaction into identifiable components to reflect the content of the transaction. It may be necessary to group two or more transactions when they are linked in such a way that the commercial effect cannot be understood without reference to the series of transactions as a whole. The transaction price is assigned to performance obligations separately in a contract based on the relative independent selling price of each separate performance obligation. (vi) Customer loyalty program Financial entities and hotels of Grupo Aval manage loyalty programs in which the customers accumulate points for their purchases, entitling them to redeem such points for prizes in accordance with the policies and the prize plan in force as of the redemption date. Reward points are recognized as an identifiable component separate from income for the service rendered, at their fair value. Income from loyalty programs is deferred and recognized in profit or loss until the entity has fulfilled its obligations to supply the products under the terms of the program or when it is no longer probable that the points under the program will be redeemed. Grupo Aval acts as the principal in a customer loyalty program if it obtains control of the goods or services of another party in advance of transferring control of those goods or services to a customer. Grupo Aval is an agent if its performance obligation is to arrange for another party to provide the goods or services. (vii) Hotel services Revenue is derived from the following sources: i) Management fees: earned from hotels managed by Grupo Aval, usually under long-term contracts with the hotel owner. Management fees include a base fee, generally a percentage of hotel revenue, which is recognized when earned in accordance with the terms of the contract and an incentive fee, generally based on the hotel’s profitability or cash flows and recognized when the related performance criteria are met under the terms of the contract. ​ ii) Owned and leased: primarily derived from hotel operations, including the guests accommodation and sales of food and beverage from owned and leased hotels operated under Grupo Aval brand names. Revenue is recognized at the point when the goods are sold or services are rendered. ​ (viii) Agriculture products Grupo Aval grows and sells agricultural products through companies owned by Corficolombiana. Sales are recognized when control of the products has been transferred, meaning when the products are delivered to the wholesaler, the wholesaler has full discretion over the channel and price to sell the products, and there is no unfulfilled obligation. Delivery occurs when the products have been shipped to the specific location, the risks of obsolescence and loss have been transferred to the wholesaler, and either the wholesaler has accepted the products in accordance with the sales contract, the acceptance provisions have lapsed, or Grupo Aval has objective evidence that all criteria for acceptance have been satisfied. ​ Revenue from these sales is recognized based on the price specified in the contract, net of discounts. Accumulated experience is used to estimate and provide for the discounts, using the most likely amount, and revenue is only recognized to the extent that it is highly probable that a significant reversal will not occur. A receivable is recognized when the goods are delivered as this is the point in time that the consideration is unconditional because only the passage of time is required before the payment is due. ​ (ix) Financing components. ​ Grupo Aval adjusts transaction prices for the time value of money for contracts where the period between the transfer of the promised goods or services to the customer and payment by the customer exceeds one year.
Description of accounting policy for earnings per share [text block]	2.28 Earnings per share Earnings per share is calculated as net income for the period attributable to Grupo Aval’s shareholders divided by the weighted average number of common and preferred shares outstanding during the period. Diluted earnings per share are determined in the same way, on the basis of net income, but the weighted average number of shares outstanding is adjusted to account for the potential dilutive effect of stock options. Grupo Aval does not have financial instruments with potential dilutive effects. As a consequence, only basic earnings per share are disclosed in these financial statements.

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 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.
