“At the time of approving the financial statements, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. The company has a strong net asset position including significant cash reserves. Furthermore, forecasts show that the companies strong performance and ability to generate cash will continue over the next 12 months. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.”
