In respect of the IPO offering and pricing mechanism, the key changes to the listing requirements include:

(1) Minimum bookbuilding placing tranche: Require an issuer to allocate at least 40% of its shares initially on offer in an IPO to its bookbuilding placing tranche. (This allocation has been reduced from 50% in the original proposal.)

(2) Allocation to public subscription tranche: Allow a new listing applicant to choose either Mechanism A or Mechanism B as its IPO offering mechanism.
