Great. Thanks, Matt. Good afternoon, and thank you for joining us on today's conference call to discuss Palo Alto Networks fiscal fourth quarter and full year 2016 financial results. This call is being broadcast live over the web and can be accessed on the Investors section of our website at investors.paloaltonetworks.com. With me on today's call are Mark McLaughlin, our Chairman and Chief Executive Officer; and Steffan Tomlinson, our Chief Financial Officer. This afternoon, we issued a press release announcing our results for the fiscal fourth quarter and full year ended July 31, 2016. If you'd like a copy of the release, you can access it online on our website. We would also like to remind you that during the course of this conference call, Management will make forward-looking statements including statements regarding our financial outlook, the impact of change in accounting policies, the spending environment and market opportunity for our products, subscriptions and services, trends in certain financial results and operating metrics, our revenue, billings, deferred revenue and free cash flow growth rates, sales productivity, seasonality, ability to expand market share, scale the business, gain leverage and deliver profitability, benefits of our partner ecosystem, innovations in our product subscription and services capabilities, our competitive position and our plans with respect to our share repurchase authorization. These forward-looking statements involve a number of risks and uncertainties, some of which are beyond our control, which could cause actual results to differ materially from those anticipated by these statements. These forward-looking statements apply as of today and you should not rely on them as representing our views in the future, and we undertake no obligation to update these statements after this call. For a more detailed description of factors that could cause actual results to differ, please refer to our Quarterly Report on Form 10-Q filed with the SEC on May 27, 2016, and our earnings release posted a few minutes ago on our website and on the SEC's website. Also, please note that certain financial measures we use on this call are expressed on a non-GAAP basis and have been adjusted to exclude certain charges. For historical periods, we've provided reconciliations of these non-GAAP financial measures to GAAP financial measures in the supplemental financial information that can be found in the Investors section of our website located at investors.paloaltonetworks.com. For planning purposes, we expect our fiscal first quarter 2017 earnings conference call to be held after the market closes on Monday, November 21. We'd also like to inform you that we will be presenting at the Citi 2016 Global Technology Conference on Thursday, September 8, the 2016 Deutsche Bank Technology conference on Wednesday September 14, and the Dougherty & Company Institutional Investor Conference on Wednesday, September 28. And finally, for your reference once we've completed our formal remarks, we will be posting them and the related slide deck to our Investor Relations website under Quarterly Results. And, with that, I will turn the call over to Mark.
