We regard Autodesk as the global industrial stand in computer -supported design software. Millions of industry professionals rely on Autodesk software to design and model buildings, produced products, animated films and video games. We think that Autodesk will remain the industrial stand, because the switching costs and the network effect continue to reinforce each other and the company is paramount in industrial trends. More than 95% of his turnover is now coming back, after a gradual transition from licenses in the last eight years. We think that the change allows Autodesk to extract more income per user as it increases its loyal and increasingly maturing basis.
