On July 25, 2016, the Company issued a press release announcing the candidates nominated to stand for election to the Company’s supervisory board at the AGM. The Company also announced the receipt of notice of resignation from two existing supervisory board members, David Chiswell, whose resignation will be effective at the AGM and Chen Yu, whose resignation will be effective September 22, 2016.

On or about July 25, 2016, The Bank of New York Mellon, in its capacity as the depositary bank (the “Depositary”) for the Company’s American Depositary Shares (“ADSs”) will commence mailing voting cards to ADS holders to enable ADS holders of record as of July 18, 2016 to instruct the Depositary to vote the common shares represented by their ADSs. If the Depositary timely receives voting instructions from an ADS holder, it will endeavor to vote the common shares (in person or by proxy) represented by the holder’s ADSs in accordance with the ADS holder’s voting instructions.
