Thank you. Before we begin, we'd like to remind everyone that this call includes certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Actual events or results could differ materially due to a number of risks and uncertainties including those mentioned in the most recent Forms 10-K and 10-Q filed by our company and QVC with the SEC. These forward-looking statements speak only as of the date of this call and Qurate Retail expressly disclaims any obligation or undertaking to disseminate any updates or revisions to any forward-looking statement contained herein to reflect any change in Qurate Retail's expectations with regard thereto or any change in events, conditions, or circumstances on which any such statement is based. On today's call, we will discuss certain non-GAAP financial measures, including adjusted OIBDA, adjusted OIBDA margin, adjusted EPS and constant currency. Information regarding the comparable GAAP metrics, along with required definitions and reconciliations, including preliminary notes and schedules one through three, can be found in the earnings press release issued today, which is available on our website. Today speaking on the call we have Qurate Retail President and CEO, Mike George; Qurate Retail Group CFO, Jeff Davis; Qurate Retail, Inc., CFO, Mark Carleton; and Executive Chairman Greg Maffei. A couple of housekeeping items before we get started. As a reminder, at the beginning of 2018, we changed our revenue recognition in accordance with new accounting standards related to recognizing branded credit card income as revenue rather than an offset to SG&A expense. Throughout our comments unless noted, we'll discuss Q4 and full year revenue results for QVC US, HSN and zulily, as if the credit card income remains an offset to SG&A expense, as it was in 2017. We believe this provides the most comparable review of our year-over-year performance. In accordance with new accounting standards, we also now recognize revenue at the time of shipment rather than delivery. We did not adjust our results for this change in our comments on this call because this impact balanced out over the course of the year. For Q4, the new delivery-based standard had an immaterial impact on Qurate Retail's reported results, so it did have an outsized negative impact on reports resulted at zulily in the fourth quarter, which Jeff Davis will discuss. Our reported results and the impact of the revenue recognition changes are included in our earnings release issued this morning and in our SEC filings. And finally, beginning this quarter, we have published slides to accompany the earnings release. These slides are available on our website. Now I'll hand the call over to Mike George.
