“The directors have carried out a review of the company's expected performance in conjunction with budgets and cash flow requirements of the business to assess going concern. This review happens regularly throughout the period by the directors to assess business performance. The company has sought assurances that the agreement will continue for at least 12 months from the date of approval of these financial statements. Further, the directors believe there will be sufficient cash reserves to enable the company to meet its obligations as they fall due, for a period not less than 12 months from approval of these financial statements. Thus, the directors continue to adopt the going concern basis of accounting in preparing the financial statements.”
Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers
