How should “t” which is used in the formulas in paragraph 1 of Article 473a CRR be calculated?
The question concerns the linkage between the definition of “t” which is used in the formulas in Article 473a(1) and the amount of DTA that is deducted from CET1 (Article 36(1)(c)) to be considered in accordance with Article 473a(7)(a), when an institution (standardized approach):
In particular, the query relates to the approach to be followed for the correct determination of the adjustment to CET1 and the net exposures value determined in accordance with Article 473a(7)(b). The possible suggested approaches are:
The variable t in Article 473a(1) of Regulation (EU) No 575/2013 (CRR) is defined as the “increase of Common Equity Tier 1 capital that is due to tax deductibility of the amounts A2, SA and A4, SA” for exposures which are subject to risk weighting in accordance with the Standardised Approach (SA exposures) and as the “increase of Common Equity Tier 1 capital that is due to tax deductibility of the amounts A2, IRB, and A4, IRB” for exposures which are subject to risk weighting in accordance with the Internal Ratings Based Approach (IRB exposures).
In order to calculate the t amount it is first necessary: (i) to calculate the amounts A2, SA and A4, SA, SA for SA exposures as well as the amounts A2, IRB, and A4, IRB for IRB exposures and second, (ii) to determine which part of these amounts is deductible for the purposes of determining taxable profit of the current year and which part is not and, as such, could give rise to the recognition of deferred tax assets (DTAs).">
Hereafter it is provided a technical analysis of the different tax effects that can be observed and its implications in prudential terms, in particular CET1 impacts.
When expected credit loss (ECL) provisions are tax-deductible the taxable profit is reduced and a lower tax amount is paid. The lower tax amount paid “implicitly” increases accounting equity, via the recognition of a lower amount of current tax in PL and consequently increases CET1 as well. For this reason, the provisioning amounts eligible for transitional CET1 add-back are net of such current tax effects. The variable “t” in Article 473a of the CRR corresponds to the amount by which the current tax amount paid is reduced due to the fact that the tax authority would recognise the amounts A2, SA and A4, SA, A2, IRB, and A4, IRB (or part of those amounts) as deductible for the purposes of determining the institution’s taxable profit.
DTAs that rely on future profitability and arise from temporary differences and DTAs from the carry-forward of unused tax losses
Article 473a(7)(a) of the CRR establishes that all requirements laid down in the CRR and in Directive 2013/36/EU that use the amount of DTAs that is deducted from CET1 in accordance with Article 36(1)(c) or risk weighted in accordance with Article 48(4) of that Regulation shall be recalculated by not taking into account the effects that the ECL provisions included in CET1 in accordance with paragraph 1 of article 473a of the CRR have on that amount of DTAs. This means that before applying the requirements of Article 36(c), Article 38 and Article 48 of the CRR to the relevant DTA amounts, these DTA amounts should be recalculated so that they do not include DTAs related to provisions that are added back to CET1. For the avoidance of doubt, DTA amounts related to provisions that are added back to CET1 should not be included in CET1 capital.
Additionally, it should be noted that the variable t does not address tax effects in the context of deferred tax assets.
