Autodesk employees,

Last month we began mailing materials for the upcoming Autodesk annual stockholder meeting to be held on Thursday, June 7, 2012. If you owned Autodesk shares (not options) on April 10, 2012, you should receive materials as part of the mailing. Please note that you may receive this information via email or regular mail depending on how you have elected to receive stockholder materials from Autodesk. Those materials will instruct you on how to submit your vote. A copy of the stockholder materials can also be viewed here:
