(26)Member States should be able to introduce a viability test as a condition for access to the preventive restructuring procedure provided for by this Directive. Such a test should be carried out without detriment to the debtor's assets, which could take the form of, among other things, the granting of an interim stay or the carrying out without undue delay of the test. However, the absence of detriment should not prevent Member States from requiring debtors to prove their viability at their own cost.
