In the same vein, where no waiver is granted, liquidity flows between two institutions belonging to the same group and which are subject to consolidated supervision, should, when the liquidity requirement becomes a binding measure, receive preferential inflow and outflow rates only in those cases where all the necessary safeguards are in place. Such specific preferential treatments should be narrowly defined and linked to the fulfilment of a number of stringent and objective conditions. The specific treatment applicable to a given intragroup flow should be obtained through a methodology using objective criteria and parameters in order to determine specific levels of inflows and outflows between the institution and the counterparty. Based on the observations and supported by the EBA report, the Commission should, as appropriate and as part of the delegated act which it adopts pursuant to this Regulation to specify the liquidity coverage requirement, be empowered to adopt delegated acts to lay down those specific intragroup treatments, the methodology and the objective criteria to which they are linked as well as joint decision modalities for the assessment of those criteria.
