An issuer may apply for admission to the Official List of the SGX Mainboard. The listing may be a primary or a secondary listing. The Exchange has absolute discretion concerning the admission of an issuer to the Exchange's Official List (and its removal) and quotation of its equity securities (and their suspension). The Exchange may approve applications for listing unconditionally or subject to condition(s), or may reject applications for listing, as it thinks appropriate. The Exchange also reserves the right to vary any such condition(s) or impose additional conditions.
