Amendment No. 2 to Registration Statement on Form F-1 filed November 13, 2019

ADS holders may not be entitled to a jury trial . . ., , page 49

1.     Your response to prior comment 2 and current disclosure indicate that
claims
       arising before the withdrawal of the shares underlying the ADSs will
continue to be

basis of that belief.
       For example, clarify what you consider to be "pre-dispute." If there is
material
       uncertainty regarding the enforceability of this position, please also
revise to address this
       uncertainty.
       We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
