It is Autodesk’s policy to limit the amounts invested with any one institution by type of security and issuer. Total sales to the distributor Tech Data Corporation, and its global affiliates (“Tech Data”), accounted for 24% and 25% of Autodesk’s total net revenue for the three and nine months ended October 31, 2013, respectively, and 24% and 23% of Autodesk's total net revenue for the three and nine months ended October 31, 2012, respectively.
