Thank you. Good afternoon, and thank you for joining us on today’s conference call to discuss Palo Alto Networks' fiscal first quarter 2018 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; Steffan Tomlinson, our Chief Financial Officer; Mark Anderson, our President and Kathy Bonanno, our newly appointed CFO. This afternoon, we issued a press release announcing our results for the fiscal fourth quarter ended October 31, 2017. If you would like a copy of the release, you can access it online on our website. We would like to remind you that during the course of this conference call, management will make forward-looking statements, including statements regarding our financial guidance and modeling points for the fiscal second quarter and full-year fiscal 2018, our competitive position and the demand and market opportunity for our products and subscriptions, benefits and timing of new products and subscription offerings, our ability to drive outside growth rates, and trends in certain financial results, operating metrics, mix shift and seasonality. 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 Annual Report on Form 10-K, filed with the SEC on September 07, 2017 and our earnings release posted a few minutes ago on our website and filed with the SEC on Form 8-K. 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 have 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. We’d also like to remind you that we will be participating in the Credit Suisse 21st Annual Technology Media and Telecom Conference in Scottsdale, Arizona on November 30, the Raymond James 2017 Technology Investors Conference in New York on December 4th, the 2017 Wells Fargo Tech Summit in Park City, Utah on December 6th, the Barclay's Global Technology Media and Telecom Conference in San Francisco on December 7th and the Cowen Networking and Cybersecurity Summit in New York on December 13th. And finally, once we have completed our formal remarks, we will be posting them to our Investor Relations website under Quarterly Results. And with that, I’ll turn the call over to Mark.
