Concentrations of Suppliers - For the years ended March 31, 2015, 2016 and 2017, the Company had no single suppliers contributed over 10% of total purchase.

Country risk - The Company has significant investments in the PRC. The operating results of the Company may be adversely affected by changes in the political and social conditions in the PRC, and by changes in Chinese government policies with respect to laws and regulations, anti-inflationary measures, currency conversion and remittance abroad, and rates and methods taxation, among other things. There can be no assurance, however, those changes in political and other conditions will not result in any adverse impact.

Investment price risk - The Company is exposed to equity and bond price risk on marketable and available-for-sale securities. The Company’s marketable securities are investment listed on the Stock Exchange of Hong Kong. Decisions to buy and sell securities are based on daily monitoring of the performance of individual securities compared to that of the Index and other industry indicators, as well as the Company’s liquidity needs. Listed investments held in the available-for-sale portfolio have been chosen based on their longer term growth potential and are monitored regularly for performance against expectations. The Company believes the exposure to investment price risk from the Company’s investment activities is acceptable in the Company’s circumstances.
