Nokia has updated its definition of the industry mobile device market which it uses to estimate industry volumes. The company said it now has better visibility of the overall market size, including the number of mobile devices sold by certain new entrants selling legitimate, as well as unlicensed and counterfeit, products. 
The new estimated market size is bigger than the company had previously estimated and Nokia’s market share is, hence, lower.
For comparative purposes only going forward, applying the revised definition and improved measurement processes and tools retrospectively to 2009, Nokia estimates that industry mobile device volumes in 2009 would have been 1.26 billion units. Based on the industry mobile device market definition used in 2009, Nokia estimated that industry mobile device volumes were 1.14 billion units. Similarly, for comparative purposes only going forward, applying the revised definition retrospectively to 2009, Nokia estimates that its mobile device volume market share would have been 34% in 2009 on an annual basis. Based on the industry mobile device market definition used in 2009, Nokia’s volume market share estimate was 38%.
Applying its revised definition of the industry mobile device market applicable beginning in 2010 on a comparable year-over-year basis, – Nokia expects industry mobile device volumes to be up approximately 10% in 2010, compared to 2009; – Nokia targets its mobile device volume market share to be flat in 2010, compared to 2009; and – Nokia targets to increase its mobile device value market share slightly in 2010, compared to 2009.
