You are urged to consult your tax advisors about the application of the PFIC rules to any lower-tier PFIC.

You will generally be required to file IRS Form 8621 if you hold our ADSs or Class A ordinary shares in any year in which we are classified as a PFIC.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is furnished to the IRS in a timely manner.

Certain U.S. holders are required to report information relating to our ADSs or Class A ordinary shares, subject to certain exceptions (including an exception for ADSs or Class A ordinary shares held in accounts maintained by certain financial institutions), by attaching a complete IRS Form 8938, Statement of Specified Foreign Financial Assets, with their tax returns for each year in which they hold the ADSs or Class A ordinary shares. Significant penalties can apply if you are required to file this form and you fail to do so. You are urged to consult your own tax advisors regarding this and other information reporting requirements relating to your ownership of the ADSs or Class A ordinary shares.
