AMS Public Transport Holdings Limited provided unaudited consolidated earnings guidance for the six months ended September 30, 2017. For the period, the company expects loss for the six months ended 30 September 2017 as compared to a profit of HKD 15,530,000 in the corresponding period in 2016. The expected loss was mainly attributable to a non-cash deficit on revaluation of public light bus ("PLB") licences and the drop in operating profit of the franchised PLB service business. As the drop in the market price of PLB licences continued, it is expected that the non-cash deficit on revaluation of PLB licences charged to the unaudited consolidated income statement for the six months ended 30 September 2017 may be more than HKD 30,000,000 (2016: HKD 1,280,000). Also, it is expected that the profit excluding the deficit on revaluation of PLB licences for the six months ended 30 September 2017 may decrease considerably owing to the inflating labour costs and fuel costs as disclosed about the Group's prospects in the chairman's statement in the Annual Report.
