(18)Institutions which do not fall within the category of small institutions referred to in Article 10 of Delegated Regulation (EU) 2015/63 and whose total assets are equal or less than EUR 3 000 000 000, involve a lower risk than that of large institutions, and in most cases they do not pose a systemic risk and are less likely to be placed under resolution, which consequently decreases the likelihood that they benefit from the Fund. It is therefore convenient to introduce a simplified calculation of the contributions to be paid by those institutions. This would also prevent possible short-term changes in the status that these institutions might undertake in order to qualify for the application of Article 10 of Delegated Regulation (EU) 2015/63. That calculation should include a component based on a lump sum. This system should avoid distortions between institutions and achieve a balanced distribution of contributions between the different types of institutions. It would also alleviate the administrative and financial burdens from the collection of individual contributions by such institutions.
