(46)The new standardised approach for operational risk introduced by the BCBS combines an indicator that relies on the size of the business of an institution with an indicator that takes into account the loss history of that institution. The finalised Basel III framework envisages a degree of discretion as to how the indicator that takes into account the loss history of an institution may be implemented. Jurisdictions are able to disregard historical losses for calculating the own funds requirements for operational risk for all relevant institutions, or to take historical loss data into account even for institutions below a certain business size. To ensure a level playing field within the Union and to simplify the calculation of own funds requirements for operational risk, that discretion should be exercised in a harmonised manner for the minimum own funds requirements by disregarding historical operational loss data for all institutions.
