Arts Optical International Holdings Ltd. provided earnings guidance for the six months ending June 30, 2015. For the period, the company is expected to be significantly lower than that of the corresponding period in 2014, and the group may even incur a loss for the six months ending June 30, 2015. The anticipated reduction in net profit or loss for the six months ending 30th June, 2015 is mainly attributable to: the decrease in the Group's consolidated revenue by 3% from HKD 639 million in the first five months of 2014 to HKD 622 million in the first five months of 2015; the significant increase in labour costs where the manufacturing facilities of the group are located, namely Shenzhen City, Heyuan City and Zhongshan City, where the statutory minimum wage increased by 12%, 20% and 15% respectively, since March 2015 for Shenzhen City and since May 2015 for Heyuan and Zhongshan Cities; the significant increase in other operating costs in mainland China in the first five months of 2015 as compared with the corresponding period in 2014; and additional costs and expenses incurred in the first five months of 2015 as the group accelerated the pace of its factory relocation project from October 2014 onwards with new buildings being constructed on the factory sites in Pingdi Town of Shenzhen City, Heyuan City and Zhongshan City, which resulted in higher depreciation charges of the buildings and leasehold improvement.
