“The company meets its day to day working capital requirements through its own cash generation and through intercompany advances from the Teledyne Group. In making their assessment, the directors have reviewed the cash resources available to the company against expected future expenditure and confirm that the company will have sufficient funds to allow it to continue to trade and meet its liabilities as they fall due for a period of at least twelve months from the date the directors sign the financial statements of the company.”

This aligns with our focus on growing turnover and operating profit.”
