      E-Mail Address:
      1 In 1991, SGX-ST (formerly known as Stock Exchange of Singapore Limited) introduced 2 policies, in consultation with the Monetary Authority of Singapore, that:—
      (1) prohibited the appointment of Approved Executive Directors and Trading Representatives to the boards of SGX-ST listed companies, and
      (2) prohibited the appointment of a director to an SGX-ST listed company as a director of a Trading Member.
      2 Trading Members are advised that the Exchange has revised these policies. The new requirements, applicable immediately, are set out below.
      3 An Approved Executive Director or a Trading Representative may be appointed as a nonexecutive director of an SGX-ST listed company (but not as an executive director) subject to the following:—
      (1) the Approved Executive Director or Trading Representative furnishing SGX-ST with:—
      (a) an explanation of how conflicts of interest that may arise from the dual appointments have been addressed, and
      (b) an undertaking to disclose to customers the directorship as and when necessary for the discharge of the Approved Executive Director's or Trading Representative's fiduciary responsibility; and
      (2) the Trading Member advising SGX-ST that it is aware of the directorship and is satisfied that conflicts of interest have been sufficiently addressed.
      4 An Approved Executive Director or Trading Representative must inform SGX-ST of the proposed appointment in accordance with SGX-ST Rule 6.2.3 and Rule 7.5.6 respectively.
      5 Possible conflicts of interest that the Approved Executive Director or Trading Representative may need to consider and address under Item 3 above include:—
      (1) When an Approved Executive Director or a Trading Representative is in a position to influence the trading decision of his customers and would recommend the listed company of which he is a director, how does he ensure unbiased advice and full disclosure to his customer?
      (2) When an Approved Executive Director or a Trading Representative possesses information about a listed company that is not generally available to the public and is in a position to influence research recommendations or corporate finance activities, how does he fulfill his obligations in respect of the listed company and Trading Member?
      6 A Trading Member may appoint a director of an SGX-ST listed company as a non-executive director (but not as an executive director).

      Under SGX-ST Rule 4.6.12, the Member must inform SGX-ST of the appointment within 7 days.
      7 An Approved Executive Director or Trading Representative who is a director of an SGX-ST listed company must keep a record of his share transactions in that company. If the Approved Executive Director or Trading Representative is required to maintain a register of securities, that will suffice. SGX-ST may inspect the record at any time or take extracts of it.

      E-Mail Address:
      1 We are pleased to inform Trading Members that following consultation with the Monetary Authority of Singapore, Remisiers can now operate in teams and enter orders for each other's customers. Trading Members and their Remisiers who wish to engage in such arrangements must observe the following:—
      (1) Prior to commencement of any team arrangements, Trading Members must approve the teams and furnish SGX-ST with the names of Remisiers who operate in teams and any subsequent updates.
      (2) If a customer's order is passed along a chain of Remisiers, each Remisier must record from and to whom he receives and transmits the order, and the time of such receipt and transmission. Trading Members must ensure that the team Remisiers do not trade ahead of their customers.
      (3) Trading Members must keep customers informed of the team arrangements, and give them the option not to be serviced by Remisiers working in teams. Trading Members should also keep their customers informed of any changes to team compositions.
      (4) Remisiers must be jointly and severally liable if customers' losses are not recovered.
      (5) Trading Members must establish in writing the terms and conditions of each team arrangement with its Remisiers. The terms and conditions must include how possible disputes amongst remisiers working in teams are resolved. Possible disputes that may arise from team arrangements include those in respect of commission allocation, trading errors, and overtrading.
      (6) Trading Members must ensure that their Banker's Guarantees are enforceable.
      (7) Trading Members must ensure that Remisiers working in teams will not compromise their compliance with all relevant legislation and regulations.
      2 Team arrangements increase the risk of a single customer or the team trading beyond the trading limit imposed. In this respect, Trading Members should closely monitor the team to ensure that customers' and Remisiers' trading limits are not exceeded, especially in the case of trades not executed on the Trading System which are not captured real time in the Trading System. Trading Members should also conduct frequent reviews of team operations to ensure that trading irregularities do not occur.
