1.1. Scope The financial entities covered are those considered “internationally active” for the purposes of complying with the rules on “Liquidity Coverage Ratio”. 1.2.

Total net cash outflows (next 30 calendar days) Foreign currency amounts will be converted daily to pesos using the reference exchange rate published by the BCRA for the US dollar, prior to applying the corresponding swap rate for other currencies communicated by this Institution's Operations Desk. The calculation will be performed on:

• Individual basis (financial entity and domestic branches only, as established in point 8.1 of the LCR rules); and
• Monthly consolidated basis, considering specific provisions on significant subsidiaries contained in point 8.2 of the cited rules. Consolidation level: 0 = Head office and domestic branches 1 = Head office, domestic and foreign significant subsidiaries (). () Entities with foreign branches will use this consolidation level, even if they do not hold significant subsidiaries to consolidate according to the “Consolidated Supervision” and “Liquidity Coverage Ratio” rules. The resulting daily values will be recorded with two decimal places. On days with no new transactions, the value from the immediately preceding day will be repeated. Without prejudice to compliance with this information regime, the provisions of point 1.5.2 of the LCR rules regarding its continuous use to contribute to liquidity risk monitoring and control must be observed, and immediate notification must be provided to the corresponding Supervision Department if its LCR has decreased (or is expected to decrease) below the established value, considering the gradual implementation schedule.

The components of the Liquidity Coverage Ratio (LCR) will be reported according to the information model codes (Section 5) per respective instructions, corresponding to the last day of the month. This requirement must be fulfilled by financial entities considered “internationally active” for LCR compliance purposes. The information will have a monthly frequency, and amounts will be recorded in thousands of pesos, without decimals. Data will be reported converted to pesos, but identifying the original currency. For rounding purposes, values will be incremented by one unit when the first digit of the fraction is equal to or greater than 5, discarding fractions if lower. Foreign currency amounts will be converted to pesos using the reference exchange rate published by the BCRA for the US dollar, prior to applying the corresponding swap rate for other currencies communicated by the Operations Desk. Nevertheless, foreign currency concepts will be identified according to their original currency, per the codification in the Centralized Information Requirements System (SISCEN), table T0003, excluding those not referenced with the SWIFT code. The requested data will be reported on an individual and consolidated basis per Section 8 of the LCR rules. For this purpose, the following consolidation levels are defined: 1: Head office and domestic branches; 2: Head office, domestic and foreign significant subsidiaries. Regarding “significant subsidiary”, the provisions of the second paragraph of point 8.2 of the LCR rules must be considered.
