Thank you, Operator, and good afternoon, everyone. Today on the call, we have President and CEO, Carl Russo; as well as Chief Financial Officer, Cory Sindelar. This conference call will be available for audio replay in the Investor Relations section of the Calix website. Before we begin, I want to remind you that in this call, we refer to forward-looking statements, which include all statements we make about our future financial and operating performance, growth strategy, and market outlook. And actual results may differ materially from those contemplated by these forward-looking statements. Factors that could cause actual results and trends to differ materially are set forth in today's earnings press release and in our annual and quarterly reports filed with the SEC. Calix assumes no obligation to update any forward-looking statements, which speak only as of their respective dates. Also on this conference call, we will discuss both GAAP and non-GAAP financial measures. Reconciliation of GAAP to non-GAAP measures is included in our earnings press release and available on our website. As a reminder, our earnings press release, supplemental financial data, and an accompanying earnings release presentation are available on the Investors Relations section of the Calix website. For the quarter ended December 31, 2017, Calix reported revenue of $137.9 million, a GAAP loss of $0.25 per share, and a non-GAAP loss of $0.15 per share. In just a moment, Carl, will begin with opening remarks; Cory, will then take you through to the quarter in greater detail, as well as provide our financial guidance for Q1, 2018; Carl with then conclude with remarks on Calix strategy and growth outlook. This will be followed by questions from analysts. With that, I would now like to turn the call over to Calix President and CEO, Carl Russo. Carl?
