Greentech Technology International Limited provided consolidated earnings guidance for the year ended December 31, 2017. The board of directors of the company inform the shareholders of the company and potential investors that based on the preliminary assessment of the group's unaudited consolidated management accounts for the year ended 31 December 2017 currently available to the board, the group is expected to record a significant drop in net profit for the year ended 31 December 2017 as compared with that in 2016. The said decrease is due to the fact that in 2016, the Group booked a significant reversal of impairment loss on the property, plant and equipment and exploration and evaluation assets of the Renison underground mine in the sum of HKD 170,421,000 (the Group held 50% of interest in such mine) based on the then estimated recoverable amount of these assets of such mine as at 31 December 2016 whereas for the year ended 31 December 2017, no such significant reversal of impairment loss will be made based on the preliminary valuation obtained by the management from the valuer.
