“Having assessed the principal risks and the other relevant matters, the directors consider it appropriate to adopt the going concern basis of accounting in preparing its consolidated financial statements. Most of the income is contracted and fixed and scenarios have been run assuming very little income from variable revenue, but which still demonstrate liquidity and compliance within debt covenants.”
Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers
