(13)In using the benchmarking results, competent authorities should consider possible data limitations and reflect this in their assessment as deemed appropriate. Additional metrics based on outturns should be calculated by EBA based on the information collected and will further contribute to the analysis. Similarly, given that own funds requirements produced by market risk models are portfolio-dependent and any conclusions obtained at disaggregated levels cannot be uncritically extrapolated to real portfolios held by institutions, any preliminary conclusions based solely on the total levels of capital derived from the aggregated portfolios should be considered with due caution. When assessing the results obtained, competent authorities should consider that even the aggregated portfolios comprising the largest number of instruments will still be very different from a real portfolio in terms of size and structure. In addition, since most institutions will not be able to model all non-aggregated portfolios, the results might not be comparable in all cases. Furthermore, it should be borne in mind that the data will not be reflecting all actions on own funds, such as constraints on diversification benefits or own funds add-ons introduced to address known modelling flaws or missing risk factors.
