Perfectech International Holdings Limited is expected to record a relatively substantial increase in its consolidated net loss for the year ended 31 December 2018 as compared to the year ended 31 December 2017, which was mainly due to the following reasons: a decrease in sales as the demand from a major customer dropped as a result of the recent Sino-American trade disputes; changes in fair value of an investment property held by the Group, which led to a loss of HKD 1,000,000 for the year ended 31 December 2018 incurred by the Group (as compared to a gain of HKD 3,300,000 for the year ended 31 December 2017).
