The information is required in the case of repurchase of shares (shares repurchased for cancellation but not yet cancelled) and redemption of shares (shares redeemed but not yet cancelled). Please state the number of shares repurchased or redeemed during the month or in preceding month(s) but pending cancellation as at close of the month as a negative number. 4.

Where the issuer has already made the relevant confirmations in a return published under Main Board Rule 13.25A / GEM Rule 17.27A in relation to the securities issued, or the treasury shares sold or transferred, no further confirmation is required to be made in this return. 5. “Identical” means in this context: ． the securities are of the same nominal value with the same amount called up or paid up; ． they are entitled to dividend/interest at the same rate and for the same period, so that at the next ensuing distribution, the dividend/interest payable per unit will amount to exactly the same sum (gross and net); and ． they carry the same rights as to unrestricted transfer, attendance and voting at meetings and rank pari passu in all other respects.
