These statements include, without limitation, statements regarding the expected outcome of pending and threatened litigation, arbitration, disputes, regulatory proceedings or investigations by authorities and other judicial bodies, as well as statements preceded by or including the word “expect,” and similar expressions. Because they involve risks and uncertainties, actual results may differ materially from the results that we currently expect. Factors, including risks and uncertainties that could cause such differences include, but are not limited to, the outcome of the binding arbitration with Samsung expected in 2016, as well as the risk factors specified on pages 74 to 89 of Nokia’s latest annual report on Form 20-F under “Operating and Financial Review and Prospects-Risk factors”, in our interim reports issued on April 30, 2015, July 30,
