(12)Accounting of derivatives is not harmonized in the Union with respect to individual accounts and therefore this could have an implication in the amount of liabilities to be considered for the calculation of the contributions of each bank. The leverage ratio methodology referred to in Article 429(6) and (7) of Regulation (EU) No 575/2013 applies to all banks and ensures that the same derivative contract, and in particular the netting between derivative contracts, will be considered in the same manner irrespective of the accounting framework to which that bank is subject. Therefore, to ensure a harmonised treatment of derivatives in the determination of the basic annual contribution allowing for the comparability of their valuation between institutions and for a level playing field across the Union, derivatives should be valued in accordance with Article 429(6) and (7) of Regulation (EU) No 575/2013. However, to ensure the predictability of the valuation of derivatives under Regulation (EU) No 575/2013, it should be foreseen that such valuation may not lead to a value which is less than 75 % of the value of the derivatives concerned under the relevant accounting framework.
