1.1. General Instructions
Amounts will be recorded in thousands of pesos and US dollars, according to their origin. In case of concepts in foreign currencies other than the dollar, monthly averages of daily balances in the original currency will be calculated and converted at the transfer rate on the last business day of the month, communicated by the Trading Desk of the Central Bank of the Argentine Republic. Obligations, whether in pesos, foreign currency, or securities, will be classified into two groups, depending on whether they belong to entities included in Group “A” and subsidiaries/branches of G-SIB entities not included in that group, or the remaining entities. Regarding foreign currency obligations other than the US dollar, originating from pending settlement transfers abroad that exceed 72 business hours from the crediting date, the same conversion criterion provided for other obligations in those currencies will apply, but the requirement and integration will be charged to currency 010. The remaining items - except those detailed in the following paragraph - will be identified according to their original currency, in accordance with the coding provided in the Centralized Information Requirements System (SISCEN), table T0003, from which those not referenced with the “SWIFT” code will be excluded. Both national public securities or BCRA monetary regulation instruments captured through deposits, as well as those deposited by entities in the “Subaccount 60 minimum cash” to integrate their respective requirements, will be reported taking into account the Securities Box Code (Caja de Valores S.A.) assigned. The corresponding average balances will be expressed in thousands of pesos or US dollars according to the denomination currency of the security or instrument and its market value. The determination of the residual maturity structure of the previous month for fixed-term foreign currency deposits will be carried out by this Institution during the information processing stage.

1.2. Requirement
1.2.1. Amounts will be recorded as monthly averages of daily balances.
1.2.2. In case different minimum cash requirement rates apply for the same period, they will be determined for each sub-period. To this end, the rates in force during each sub-period will be applied.

The requirement to apply will be that resulting from the difference between what is determined for these obligations and the normal calculated according to section a). The entity will report these items with the incremental requirement already
