Kingston Financial Group Limited provided consolidated earnings guidance for the six months ending September 30, 2018. The board of directors of the Company informed the shareholders and potential investors of the Company that the Company and its subsidiaries anticipates to report a significant decrease in its consolidated net profit for the six months ending 30 September 2018 as compared with the corresponding period in 2017. Such a possible significant decrease was primarily attributable to, among other factors, a one-time write off of the Group's intangible assets with a carrying amount of HKD 266,157,000 as at 31 March 2018, due to the receipt on 14 September 2018 of a notice regarding the cancellation of all the 15 subsurface mineral leases held by the Group. Such mineral leases were non-core assets of the Group and were not related to the principal lines of businesses of the Group.
