(8)When reporting on market risk, the institutions should provide an initial market valuation of each individual instrument to assess whether they understood the instrument correctly. That will also ensure that institutions introduce the positions in their systems. The institutions should also report the initial market valuation to their competent authorities and the EBA ahead of the portfolio-modelling outcome, on which the assessment of the risk-weighted exposure amounts referred to in Article 78(3) of Directive 2013/36/EU will be based.
