- Affirmed
“At the time of approving the financial statements, the directors believe that the company has adequate resources to continue in operational existence for a period of twelve months from when the financial statements are authorised for issue, being the going concern period. In addition, the company has received a letter of support from its ultimate parent undertaking and the directors are satisfied that the parent is in a position to be able to provide this financial support. Thus, the directors continue to adopt the going concern basis of accounting in preparing the financial statements.”
