“The financial statements have been prepared on a going concern basis as the company's parent undertaking (Carl Zeiss AG) has confirmed that it will provide such financial support and other support as necessary to enable the company to meet its liabilities for the foreseeable future. The directors have a reasonable expectation that the Carl Zeiss group has adequate resources and liquidity to continue in operational existence for the foreseeable future. Accordingly, the directors consider it appropriate to adopt the going concern basis in preparing these financial statements.”
