Thank you. Good afternoon, everyone. And welcome to Alarm.com's fourth quarter 2017 earnings conference call. As a reminder, this call is being recorded. Joining us today from Alarm.com are Steve Trundle, President and CEO and Steve Valenzuela, CFO. Before we begin a quick reminder to our listeners. During today's conference call, management's discussion will include forward-looking statements, which may include projected financial results or operating metrics, business strategies, anticipated future products and services, anticipated investment and expansion, anticipated market demand or opportunities and other forward-looking statements. These forward-looking statements are based on our current expectations and beliefs, and on information currently available to us. Statements containing words such as anticipate, believe, continue, estimate, expect, intend, may, will and other similar expressions are intended to identify such forward-looking statements. These statements are subject to risks and uncertainties, including those contained in the Risk Factors section of our most recent annual report on Form 10-K filed with the Securities and Exchange Commission, and subsequent reports that we file with the Securities and Exchange Commission that could cause actual results to differ materially from those contained in the forward-looking statements. Please note that these forward looking statements made during this conference call speak only as of today's date and Alarm.com undertakes no obligation to update them, to reflect subsequent events or circumstances, other than the extent required by law. Also during the call, management's commentary will include certain non-GAAP financial measures and provide non-GAAP guidance. Management believes that use of these non-GAAP financial measures provides an additional tool for investors to use, in understanding company performance and trends, but note that the presentation of non-GAAP financial information is not meant to be considered in isolation, or as a substitute to the directly comparable financial measures prepared in accordance with GAAP. Reconciliations between GAAP and non-GAAP metrics for our reported results can be found in the financial statement of our earnings press release, which we have posted to our Investor Relations Web site, at investors.alarm.com. This conference call is also being webcast and available on our Investor Relations Web site. The webcast of this call will be archived, and a telephonic replay will be available on our Web site. So with these formalities out of the way, I'd now like to turn the call over to Steve Trundle. You may begin.
