Where insolvency proceedings are being conducted against the assets of debtor companies in a group of companies before different insolvency courts, the courts are obliged to cooperate and, in particular, to exchange information which may be of relevance to the other proceedings. In particular, this applies in respect of
1. the ordering of protective measures,
2. the opening of proceedings,
3. the appointment of an insolvency administrator,
4. key procedural decisions,
5. the amount of the insolvency estate and
6. the submission of insolvency plans as well as other measures to terminate the insolvency proceedings.
