»The assumption of responsibility of the managing director of a GmbH for the insolvency risk of the creditors through the claim in the regular insolvency proceedings«: The thesis deals with the question to what extent the liability risk of the managing director in the insolvency of a GmbH serves or should serve to reduce the insolvency risk of the unsecured creditors. The study shows that the regulations on the assumption of risk in German corporate and insolvency law, in particular § 64 GmbHG a.F. and § 15a InsO, must be harmonized so that the managing director is only liable for the insolvency risk of the unsecured creditors for which he is responsible.
