- Going concern
- Affirmed
“The Company has considerable financial resources together with long-term contracts with a number of customers and suppliers across different geographic areas and industries. As a consequence, the directors believe that the Company is well placed to manage its business risks successfully despite the current uncertain economic outlook. Further, the Company has received a guarantee from its parent company Celerion Inc. that financial support will be available for a period of at least 12 months from the approval of the statutory accounts. After making enquiries and assessing the ability of Celerion Inc. to provide financial support, the directors have a reasonable expectation that the Company has adequate resources to continue in operational existence for the foreseeable future. Accordingly, they continue to adopt the going concern basis in preparing the annual report and accounts.”
Significant events
