5.1.3. Reduction of the requirement for financial entities from Group 2 belonging to Groups “A”, “B” and “C”. 5.1.3.1. This requirement reduction will apply to entities from Group 2 belonging to Groups “A”, “B” and “C” that are not subsidiaries or branches of global systemically important entities (G-SIB). 5.1.3.2. Reduction. General limit. The corresponding requirement reduction will be reported in items 36000001 or 36000004 when the applicable limits on the average of credit risk requirements for the 36 months prior to submission are lower than that reported in code 70300000. This calculation will follow the following expression: where: (∑ from 1 to 36 ERC(n-1) + ... + ERC(n-36)) / 36 = average of the credit risk requirements corresponding to the 36 months prior to the reporting period, expressed in homogeneous currency of the month preceding the calculation. ERC = Item 70100000 + ∑ 8XX00000 This reduction will apply to entities meeting the requirements referred to in point 5.1.3.1., above. 5.1.3.3. Reduction. Special limits. When the entity's rating in all aspects provided for in the relevant regulatory provisions allows the application of percentages lower than those indicated in point 5.1.3.2., the resulting requirement reductions will be reflected in items 36000002, 36000003, 36000005 or 36000006 -provided their amount is lower than that recorded in item 70300000-, as detailed below: B.C.R.A.
