138Moreover, the adoption of Law No 4050/2012 is justified by prudential considerations as referred to in Article 124 TFEU. These are defined by Article 2 of Regulation No 3604/93 as considerations which underlie national laws, regulations or administrative actions based on, or consistent with, EU law and designed to promote the soundness of financial institutions so as to strengthen the stability of the financial system as a whole and the protection of the customers of those institutions. Draft Law No 4050/2012 contributed to preserving both Greek public finances and the stability of the financial system in the euro area (see paragraphs 105 and 106 above).
