1.     We note your revised disclosures do not appear to fully address the
issue noted in
       Comment 5. For example, although you allude to the issuance of ordinary
shares
       described under "The Reorganization," your disclosure does not provide
further details
       on share amounts. Upon finalization of reorganization and offering
transactions, please
       confirm that you will include detailed disclosures regarding the
adjustments made in
       arriving at the pro forma and pro forma as adjusted amounts
