1. Member States shall ensure that, when applying the bail-in tool, resolution authorities assess on the basis of a valuation that complies with Article 36 the aggregate of:
(a) where relevant, the amount by which bail-inable liabilities must be written down in order to ensure that the net asset value of the institution under resolution is equal to zero; and
(b) where relevant, the amount by which bail-inable liabilities must be converted into shares or other types of capital instruments in order to restore the Common Equity Tier 1 capital ratio of either:
(i) the institution under resolution; or
(ii) the bridge institution.
2. The assessment referred to in paragraph 1 of this Article shall establish the amount by which bail-inable liabilities need to be written down or converted in order to restore the Common Equity Tier 1 capital ratio of the institution under resolution or where applicable establish the ratio of the bridge institution taking into account any contribution of capital by the resolution financing arrangement pursuant to point (d) of Article 101(1) of this Directive, and to sustain sufficient market confidence in the institution under resolution or the bridge institution and enable it to continue to meet, for at least one year, the conditions for authorisation and to continue to carry out the activities for which it is authorised under Directive 2013/36/EU or Directive 2014/65/EU.
Where resolution authorities intend to use the asset separation tool referred to in Article 42, the amount by which bail-inable liabilities need to be reduced shall take into account a prudent estimate of the capital needs of the asset management vehicle as appropriate.
3. Where capital has been written down in accordance with Articles 59 to 62 and bail-in has been applied pursuant to Article 43(2) and the level of write-down based on the preliminary valuation according to Article 36 is found to exceed requirements when assessed against the definitive valuation according to Article 36(10), a write-up mechanism may be applied to reimburse creditors and then shareholders to the extent necessary.
4. Resolution authorities shall establish and maintain arrangements to ensure that the assessment and valuation is based on information about the assets and liabilities of the institution under resolution that is as up to date and comprehensive as is reasonably possible.
