(10)The prior permission regimes for reducing own funds, laid down in Article 78 of Regulation (EU) No 575/2013, and for reducing eligible liabilites instruments, laid down in Article 78a of that Regulation, both aim at ensuring compliance with regulatory requirements related to own funds and to own funds and eligible liabilities, and have a number of similar features. It is therefore necessary to standardise the processes followed by competent authorities and resolution authorities for both the general prior permission referred to in Article 78(1), second subparagraph, and Article 78a(1), second subparagraph, of Regulation (EU) No 575/2013, and any other permissions referred to in those Articles. Furthermore, to ensure that the specificities of any prior permission are taken into account, and to ensure that those permissions are appropriately used for their specific purposes, it is necessary to lay down that competent authorities and resolution authorities should be required to specify the period for which a prior permission other than a general prior permission is granted, and a maximum limit for that specified period should be established.
