Arts Optical International Holdings Limited provided earnings guidance for the six months ended June 30, 2019. The Group is expected to record a substantial loss for the six months ended 30th June, 2019. The Board anticipates that the Group will report an increase in loss for the six months ended 30th June, 2019 in comparison to the Adjusted Loss. This is mainly due to significant reduction in customers' sales orders and production volumes in quarter two of 2019 after the U.S. President threatened to increase tariff on USD 200 billion of Chinese goods from 10% to 25% in early May of 2019. Moreover, the fair value gain on revaluation of investment properties for the six months ended 30th June, 2019 will be below HKD 1 million. The loss of the Group for the six months ended 30th June, 2018 was HKD 24.4 million, which was mainly offset by the fair value gain of HKD 20 million on revaluation of investment properties. If this one-time gain was excluded, the loss of the Group for the six months ended 30th June, 2018 would be increased to HKD 44.4 million.
