Recital 5
(5) The output floor represents one of the key measures of the Basel III reform. It aims to limit the unwarranted variability in the own funds requirements produced by internal models and the excessive reduction in capital that an institution using internal models can derive relative to an institution using the standardised approaches. By setting a lower limit on the own funds requirements that are produced by institutions’ internal models of 72,5 % of the own funds requirements that would apply if standardised approaches were used by those institutions, the output floor limits the risk of excessive reductions in capital. To that end, institutions using internal models should calculate two sets of total own funds requirements, with each set aggregating all own funds requirements without any double counting. Implementing the output floor faithfully would increase the comparability of institutions’ capital ratios, restore the credibility of internal models and ensure that there is a level playing field between institutions that use different approaches to calculate their own funds requirements.
