Remarks:

1) Prior to 1 April 2016, the Group recognised certain incentives received from suppliers as part of its revenue or offset against the Group's selling expenses. During the year end 31 March 2017, the Group has revisited its arrangements with its suppliers and considered incentives received from suppliers for which the Group did not provide any separable identifiable promotion service, should be accounted for as a reduction of its cost of sales. Adjustments have been made to reclassify the comparative information to conform with the current year presentation.

2) The Group has adopted HKFRS 16 retrospectively from 1 April 2019, as permitted under the special transition provisions in the standard. Comparative information has not been restated, and thus comparative figures may not be comparable as comparative information were prepared under HKAS 17 "Leases".

3) The Group has adopted HKFRS 16 "Leases" from 1 April 2019, the payment of lease liabilities (including interest) are classified as financing activities rather than as operating activities in previous years.
