(“Autodesk,” “we,” “us,” “our,” or the “Company”) as of July 31, 2018, and for the three and six months ended July 31, 2018 and 2017, have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information along with the instructions to Form 10-Q and Article 10 of Securities and Exchange Commission (“SEC”) Regulation S-X.
