Danessa Signature 2 Manager of Information Regime Principal Manager of Information Regime and Information Central Offices Functional Position ANEXO (Annex) 6.1. Foreign currency / TP. 6.1.1. General instructions. 6.1.1.1. The information will be recorded in two files named "EFVOMIN.TXT" (design 5751) and "FRANEM.TXT" (design 5753), which will contain the data according to the record designs as per models inserted in point 6.1.3., which must be recorded according to what is provided in point 1.2.3.2. of Section 1 Submission of Information to the Central Bank. The aforementioned files must be sent according to what is established in point 1.2.2. of Section 1 Submission of Information to the Central Bank for the file transfer service on the exclusive site www3 (MFT). 6.1.1.2. All accounts must be differentiated by currency or type, as applicable (except what is provided in point 6.1.1.5.), using for this purpose the “Currency/type Code” field provided in the record designs. This field will be completed taking into account the following guidelines:

• Accounts with codification “/M”: the codification provided in the Centralized System for Information Requirements (SISCEN), table T0003, will be used, excluding those not referenced with the SWIFT code. If they were one or two-digit codes, this field will be completed with leading zeros to reach five positions. For example, in the case of United States dollars, account 00010 will be reported.
• Accounts with codification “/TP”: the Código de Caja de Valores S.A. code will be used. 6.1.1.3. In case of submitting a correction for a specific period, where: i) the amount of account 750000 “Transferable Deficit” in one or more currencies or types differs from the originally reported; ii) account 750000 is not reported although it was originally reported in one or more currencies or types; iii) account 750000 is reported in one or more currencies or types, although it was not originally reported; iv) increases or decreases, or modifications in the amounts stated for account 10140X/M (for M different from pesos) were verified; It will be necessary to correct the information corresponding to all subsequent validated periods that are affected. Until compliance with the above is verified, pending processing will be maintained in corrections that fall under these situations, as well as the original submissions corresponding to subsequent periods.

The Central Bank of the Argentine Republic (BCRA) will perform the corresponding calculations taking into account the following considerations: i) Calculation of the monthly requirement (907000/M, 903000/M and 905000/TP): The applicable requirement rates for the reporting period will be applied to the included accounts (907000/M and 905000/TP), plus, if applicable, the value of additional requirements (increases) (903000/M), considering for fixed-term deposits and reprogrammed deposits the amounts determined according to the procedure described in subsection iv) of this point. Each product will be rounded to the last integer, resulting in the requirement as the sum of these. Transferable deficits and exemptions shall not be considered in this account. ii) Calculation of the monthly computable integration (accounts 904000/M and 906000/TP): The concepts admitted according to current regulations will be computed. Exemptions shall not be considered in this account. iii) Computation of account 750000/M-TP in determining the position and controlling the maximum transferable amount: For its determination, the effect of exemptions on the requirement and integration, respectively, must be taken into account. The amount will be reported taking into account the instructions of point 1.4.1. of the consolidated text (CT) of this regime's procedural rules (PR). Nevertheless, to determine the maximum transferable amount and the position of the reporting period (n), the amount stated in this account will be adjusted to the numerals of this period through the following calculation: Amount account 750000/M-TP * Numerals of period (n+1) / Numerals of period (n). B.C.R.A. SUBMISSION OF INFORMATION TO THE CENTRAL BANK Section 6. Minimum cash and application of resources. Version: 12a. COMMUNICATION “A” 8420 Validity: 11/04/2026 Page 2 The resulting amount from the above expression shall not exceed the percentage established by the BCRA on the adjusted minimum cash requirement, rounded to the last integer. iv) The calculation of the fixed-term deposit structure in foreign currency applicable to the reporting period will be performed by the BCRA. This structure will be determined for fixed-term deposits, based on the amounts reported for this concept in the period prior to the reporting period, and will be applied to the totals registered in the information period for all tranches of this account, determining one structure per each reported currency. The calculation method will be as follows: a) The different tranches of each category of fixed-term deposits reported in the prior period (account 10140X/M) will be summed, determining a single total for all tranches and categories; b) The amounts of both categories of account 10140X/M will be summed, so as to obtain a single subtotal for each residual term tranche in which they were reported; c) The percentage that each calculated subtotal by tranche represents relative to the total fixed-term deposits obtained in subsection a) will be calculated, rounding to two decimals, except for the percentage corresponding to the last tranche, which will be calculated by difference between 100% and the sum of the remaining percentages; d) For the amounts reported in the reporting period in account 10140X/M, a total will be calculated for each reported currency. e) The percentages determined in subsection c) above will be applied to the totals obtained in subsection d), rounding to the last integer. If differences still exist between the amounts thus determined and the total of each deposit concept for the period, the difference will be added or subtracted, as applicable, to the amount corresponding to the tranche subject to the lower rate.

In those periods where no amounts of accounts included in any currency are registered, accounts 903000, 904000 and 907000 must be reported with the “Currency/type Code” and “Amount” fields equal to zero. If for any currency it is verified the existence of requirement accounts, but not integration accounts, accounts 903000 and 907000 will be reported with the currency code and corresponding amount, and 904000 with the same currency code and “Amount” field equal to zero. The analogous procedure will apply in case integration accounts were reported but not requirement accounts. 6.1.1.6. Accounts 905000 and 906000 will be reported with the “Currency/type Code” and “Amount” fields equal to zero when no amounts are registered for any type. When amounts are reported in account 500000/TP for a type that does not register covered deposits (account 300000/TP), accounts 905000/TP and 906000/TP of that type will be reported with an amount equal to zero. 6.1.2. Particular instructions. 6.1.2.1. Design 5751: i) A record must be recorded per account –point 1.10. of the Information Model of this regime's procedural rules (PR)– and currency/type code, and those without amounts will not be recorded, except what is provided in subsections iv) and vi) first paragraph of this point and in point 6.1.1.5. ii) Amounts must be reported without sign. iii) The sum of accounts 1XXXXX and 20XXXX, for each currency code, will be stated in accounts 100000 and 200000 of each currency, respectively. The sum of accounts 300XXX, for each type code, will be reported in account 300000 of each type. Accounts 600000/M, 800000 and 900000/M will not be reported. iv) Accounts 903000, 904000 and 907000, for each currency code in which requirement and integration accounts are reported, must always be recorded, even if they result equal to zero, as they are totals for control. Similar treatment will apply to accounts 905000 and 906000. Account 903200/M will only be reported when its amount results greater than zero. B.C.R.A.
