EBU Single Rulebook Q&A 8 December 2017 2017_3630 Write down or convert bail-inable liabilities following Article 48(3)

How would the resolution authority write down or convert bail-inable liabilities referred to in point (e) of Article 48(1) of Directive 2014/59/EU (BRRD) without previously reducing or converting the other instruments, regardless of the terms mentioned in points (a) and (b) of Article 48(3)?How should "substantially" in Article 48(5) be interpreted exactly?
