11. Additional informationxvi

OppenheimerFunds, Inc. ("OFI") is a registered investment advisor with the U.S. SEC. Its ultimate parent company, Massachusetts Mutual Life Insurance Company, qualifies for disaggregation under FSA regulations. The shares of the issuer are held by investment accounts managed by OFI. The Oppenheimer Global Fund, an investment account managed by OFI, holds greater than the 5% of the issuer's voting rights (a notifiable threshold) and is thereby disclosed in Section 9 above. OFI last disclosed, in aggregate, a position of 18.41% as of 15 July 2016 and since subscribed for 22,750,000 Placing Shares. Since the admission and settlement of Earthport Plc's Placing Shares on 24 October 2017, OFI's aggregate % of voting rights decreased by more than 1% to 14.42%. The decrease is due to the change in categorization of certain OFI accounts where OFI does not have discretion over voting rights for those funds/accounts. OFI continues to have investment discretion over 18.20% of the issuer's outstanding shares.
