- Affirmed
“In carrying out their duties in respect of going concern, the directors have carried out a review of the company's financial position and cash flow forecast for a period of 12 months from the date of the financial statements. Following this review, including consideration of the uncertainties brought about by the current economic environment and taking into account the strength of the company's net asset position, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. Thus, they have adopted the going concern basis of accounting in preparing the annual financial statements.”
