"material uncertainty" of gns's debt financing

The following is quoted from KPMG's "Independent auditor's review report" in GNS HY report.

Material uncertainty regarding Group debt financing arrangements

Without qualification to the conclusion set out above, we draw attention to note 3 in the financial report which details the status of the Group's financing arrangements. The matters set out in note 3 indicate the existence of a material uncertainty in respect of refinancing requirements in the course of the next twelve months. The Group's ability to operate as a going concern and therefore whether it will realise its assets and extinguish its liabilities at the amounts stated in the financial report is dependent on the maintenance of appropriate long-term debt facilities.

As I remember similar words were also heard in GTP/TIM's reports about one year before their collapse.
