Risk factors

We refer to the description of risk factors in the 2016 annual report, pp. 42-50, as supplemented by the description of risk factors in our most recent annual report on Form 20-F filed with the U.S. Securities and Exchange Commission, pp. 5-47. In summary, the principal risks and uncertainties faced by us relate to: product development, regulatory approval and commercialization; our reliance on third parties; our financial position and need for additional capital; our competitive position; our intellectual property; our organization, structure and operation (including but not limited to certain risks related to our status as a U.S. publicly listed company following the public offering of shares (in the form of ADSs) and listing on NASDAQ in May 2015) and market risks relating to our shares and ADSs.

We also refer to the description of the group’s financial risk management given in the 2016 annual report, pp. 130-134, which remains valid.
