Thank you, Courtnee, and welcome to everyone joining the call. This is our first full quarter of earnings since creating the asset-backed Qurate Retail stock. Many of you attended our Investor Day in May, where we shared our vision and strategy for the new organization. Today, in addition to covering our second quarter results, I'd covering our second quarter results, I'd like to lend some further perspective on the progress we're making and where we're taking the company. Our results this quarter were directionally in line with the expectations we communicated at our Investor Day. Looking at the headlines for our key brands and business lines. QVC U.S. generated its fourth consecutive quarter of revenue growth. Adjusted OIBDA margins were challenged primarily due to difficult comps with onetime gains a year ago, along with continued pressure from decline in average selling prices. We're starting to make headway on ASPs, and we'll have more favorable prior year margin comparisons in the back half. QVC International experienced soft demand in Japan and Italy, which, combined with heightened clearance activity in the U.K. and Germany and other expense pressures, led to a significant decline in OIBDA margin. HSN is still in the early stages of turnaround. In Q2, we focused on quality of sales, resulting in adjusted OIBDA margin expansion despite the weak revenue trend. There's a lot more to do here, but we're excited about a number of compelling brand launches later this fall and other initiatives aimed at moderating the sales erosion. zulily once again posted outstanding results supported by strong customer growth. Cornerstone achieved strong growth at Garnet Hill and Ballard Designs but was challenged by poor results at Frontgate. At Frontgate, we have new leadership in place along with significant brand and product work to turnaround that business. Overall, our teams are executing on multiple fronts to achieve the financial performance we're capable of while also delivering on our strategic priorities. We see Qurate Retail playing a unique role at the intersection of four mega trends that are transforming retail: the explosion of digital media consumption, the continued growth of e-commerce, the rising importance of social and influencers on product discovery and the growing value consumers place on differentiated, engaging and highly curated retail experiences. As the industry leader and the company that virtually invented video commerce, we're in a unique position to place Qurate Retail at the head of this industry transformation. We aspire to define the third way to shop, differentiated from both traditional store-based retailing and transactional e-commerce. We invite customers on a daily journey of discovery across all the digital and media platforms important to today's consumer, whether or not they have any specific purchase intent. We believe that the differentiated retailing experience we've developed through our proven broadcast model serves as a foundation for growth as we leverage these capabilities to invite new generations of customers to experience us over emerging video and digital platforms. While we're still in the early innings of these strategies, we're encouraged by recent successes, which gives us confidence to significantly accelerate our digital initiatives focused on four priorities. First, we want to ensure that our live programming is accessible and viewed wherever our target customers are accessing live content. We'll focus on increasing viewership on our own mobile platforms, on Facebook Live, through interfaces like Roku and Apple TV and on other emerging platforms that are relevant for our target customers. Second, we're creating digital-only merchandise assortments, programming and events that will appeal to new generations of consumers and also drive incremental engagement and sales from existing customers. We're investing and expanding our buying teams and experimenting with new forms of content. At QVC U.S., for example, we recently held our first-ever Black Friday in July event, targeting new and less engaged customers, featuring 12 hours of live programming exclusively designed for and distributed over digital platforms. The event significantly exceeded our expectations. We attracted over five million viewers on Facebook Live, eight times the viewership we see on a typical day; drove meaningful incremental sales; and achieved our highest single-day customer acquisition of the month. For a younger generation of potential customers, we just launched a pilot of a few digital- only beauty micro brand platforms that are promoted exclusively on social media services like Instagram. These platforms provide a gathering place for engaged beauty consumers and influencers and serve as marketplaces for the Qurate Retail family of beauty products across QVC, HSN and zulily. And in the U.K., in Q4, we'll start a new digital beauty website targeting non-QVC customers called Kelly. Third, we're creating compelling interactive experiences leveraging the growth in over-the-top platforms such as Roku and Apple TV. We just launched a new interactive over-the-top service in Germany that leverages learnings from our success with Roku. It will feature all four German networks, a variety of video-on-demand programming and the ability to filter programs by category, allowing fast, easy access to relevant content. Fourth, we're building new capabilities and increasing investments in performance marketing to drive consumers to these new experiences. And I'm really thrilled with the team's progress here. We've completed the integration of the HSN marketing team into our Qurate Retail in-house marketing agency and have hired around 20 new marketing team members from companies like Google and Amazon in just the last few months. We're aggressively ramping our customer acquisition efforts, especially on paid social channels, where we can tell compelling stories and attract new customers with high lifetime value. We're also building on zulily's success in scaling customer retention programs on channels such as Facebook to drive incremental demand from existing customers and reactivate customers who haven't purchased recently. zulily is also continuing to advance its machine learning capabilities to help us optimize performance marketing across Qurate Retail. We deploy new marketing technology tools to automate and scale our ad generation process and further target and maximize the impact of our spend. Through all of our marketing efforts, we're focused on driving breakthrough innovation that supports our unique platform. For example, we are working with Facebook on a program to use paid marketing to boost viewership of our Facebook Live original and simulcast programs. Over the last two months, we've been able to use a modest level of marketing spend to, in some cases, double or better than double the viewership of top-rated programs like In The Kitchen with David and Friday Night Beauty on Facebook Live. Our gains in performance marketing and our increasing relevance with customers across a range of interactive and digital platforms is highlighted by the outstanding customer growth and engagement metrics we're seeing. In our press release, we report our customer base on a trailing 12-month basis, but I'd also like today to share some customer metrics for just the second quarter to give you a better sense of the recent gains year-over-year. At QVC U.S., new customers grew 6% in the quarter, reactivated customers grew 6% and total customers increased 5%. At QVC International, new customers grew 9%, reactivated customers grew 6% and total customers grew 4%. Finally, at zulily, total customers grew 29%. Putting these numbers in perspective, we achieved a record-high second quarter customer count at both zulily and QVC International, and QVC U.S. was just shy of its all-time second quarter record. At QVC U.S., the strong customer growth was driven by continued gains in top-of-the-funnel engagement across platforms. On broadcast TV, total viewing minutes increased 1% across QVC and QVC2. That's the fifth consecutive quarter of broadcast viewership gains. And I would note that this result does not include our third network, Beauty iQ, which will further add to the growth rate. In addition, the strategies I outlined to drive viewership on new digital media are also paying off. Viewing minutes of our live programming and on-demand video over our web, mobile, over-the-top and Facebook Live platforms more than doubled from last year, and we believe we can grow even faster in the coming months through some of these newer initiatives that I've highlighted. While we focused heavily on digital innovation and customer growth, our integration work is also progressing on plan. We delivered $8 million of cost synergies in Q2 and $14 million in the first half, and we're on track for $35 million to $45 million for the full year. Approximately 80% of these cost synergies are expected to benefit adjusted OIBDA while the remainder relate to stock-based comp expense. We're also adding strong talent in key executive roles who will help us realize the full potential of our new company. Mary Campbell was appointed our Chief Merchandising and Interactive Officer. Mary has held various leadership roles across merchandising, planning and commerce platforms during her 20 years at the company. In her new role, she'll help us drive our product leadership agenda and spearhead innovation on our interactive platforms and with performance marketing. Next week, Jeff Yurcisin will take the reins at zulily. He comes from Amazon with an impressive track record of building a number of businesses, most recently its private brands business. He brings a strong passion for our people and our customers as well as a real focus on innovation that will continue to drive and accelerate the zulily business, but he's also well positioned to help us navigate this digital transformation at HSN and QVC. Aidan O'Meara will be leading QVC International. He brings 25 years of experience at VF, leading international teams and is well suited to drive the next phase of growth for the global business. Tom Bazzone joined us in June as President of Frontgate, the largest business in the Cornerstone portfolio. I've highlighted a number of areas of progress: Doubling down on digital innovation across platforms, building distinctive marketing capabilities, driving customer engagement and growth, getting key integration milestones and building our leadership teams. These gains put us in a strong position to deliver on our strategy and on our financial plans. More near term, we expect to see improvement in our overall margin profile in the second half of 2018, driven by the action plans detailed at Investor Day as well as the easing of some of the onetime headwinds that we faced in the first half. Before taking a closer look at the second quarter results by segment, let me provide perspective on the recent decision by the Supreme Court regarding the collection of sales tax by remote sellers. Using full year 2017 revenue as a proxy, approximately 15% of Qurate Retail's domestic sales are impacted by this decision. We're working toward collecting sales tax in the required states based on guidance provided by each state and expect to collect sales tax in substantially all the required states by the start of 2019. Turning now to the second quarter results, starting with QVC U.S. We delivered our fourth consecutive quarter of revenue gains, though growth is not yet at the level we want. Now revenue grew 2% adjusted for the credit card income component of the revenue recognition changes on strong unit volume growth of 6%, partially offset by 4% decrease in average selling prices. As you may recall, last year, approximately 1% of sales shifted from Q2 to Q3 due to a systems outage at the end of the quarter that delayed shipments. This benefited our results this quarter and will have a corresponding negative impact in Q3. Our fashion business remains strong with outstanding growth across apparel, handbags, footwear and intimate apparel. Consumer electronics and jewelry remain challenged. Home was mixed, with strength in home improvement and health and fitness offset by softness in home decor and cooking and dining. And beauty was down slightly. We're focused on getting back to consistent growth in home and beauty, and we also see more opportunities for consumer electronics in the back half. QVC U.S. operating income increased 28%, and operating income margin increased primarily due to lower purchase accounting amortization. Reported adjusted OIBDA margin declined 110 basis points after normalizing for the change in revenue recognition for private label credit card income. As we shared at Investor Day, we anticipated a number of pressures on adjusted OIBDA margin in the quarter, and we performed somewhat better than expected. We also remain confident these pressures will ease in the second half. Gross margin was flat when excluding the impact of the credit card change. We saw improved product margins due to higher mix of fashion as well as freight savings. These gains were offset by higher warehouse costs due to ASP deleverage. SG&A expenses increased due to higher bad debt expenses, resulting from a favorable bad debt adjustment in the second quarter of 2017, investments in performance marketing and higher fixed costs, which includes the impacts from a change in bonus allocation at QVC. These factors were partially offset by lower customer service costs due to the increase in digital and mobile penetration. In total, approximately 70% of the adjusted OIBDA margin contraction was driven by non-operating items, with the largest being the prior period bad debt reserve adjustment. We'll have more favorable margin comparisons in the back half due to fewer onetime pressures, and we expect to make progress on ASPs by better managing offer prices and overall product mix. Finally, in the U.S., I would note that the change to recognize revenue at the time of shipment rather than delivery had a modestly negative impact unlike in Q1, where it had a favorable impact. Under the prior accounting treatment, adjusting for both the Q Card impact and the time of shipment, Q2 net revenue would have grown 3% and adjusted OIBDA would have been essentially flat. Moving on to QVC International. Revenue increased 7% in U.S. dollars, reflecting favorable exchange rate fluctuations as the dollar weakened against the euro, pound and yen. Revenue grew 1% in constant currency while operating income margin decreased 70 basis points and adjusted OIBDA margin fell 230 basis points. These results are well below what we typically deliver in our international operations and are traceable to unique mix of factors. We're focused on getting better results in the back half. The top line slowdown was driven by soft demand in Japan and Italy. These sales pressures reflected specific challenges in each market, including weak TSV performance in Japan and lapping an advertising campaign in Italy. We achieved substantial improvements in the international sales trend in June. Turning to the operating income margin, adjusted OIBDA margin contraction. There are two primary drivers. The first was a heightened level of clearance and liquidation activity and increased inventory obsolescence in the U.K. and to a lesser extent, in Germany, which also put pressure on freight and warehouse costs due to ASP deleverage. This was the primary driver of the 130 basis point gross margin decline in international. We believe the clearance actions are largely behind us as we move into the back half, significantly lessening the gross margin pressure. We also had a freight rate increase in Japan as demand is consistently outrunning carrier capacity in that market. Second, fixed costs and commission expenses increased approximately 100 basis points due to sales deleverage and growth investments, among other factors. While we expect these expense challenges to lessen in the back half, we will continue to see some pressure from freight, commissions and other investments. Turning to HSN. As I shared at Investor Day, we fully expected sales trends to be as challenging in Q2 as they were in Q1. We're prioritizing profitability improvement and better quality of sales so that, ultimately, as we rebuild revenue, we're doing so on a strong foundation. The quarter played out as expected. Sales and customer count continued to decline, but we began to see significant margin improvement. We focused particularly on improving discipline around pricing and promotion and shipping and handling charges, along with achieving the acquisition synergies. Operating income and operating income margin declined primarily due to purchase accounting amortization. Adjusted OIBDA was down 8% on a 12% sales decline. Adjusted OIBDA margin expanded 40 basis points adjusting for the private label credit card income. The improvements stem from our strategic initiatives, especially on the gross margin line. Sales from merchandise on clearance, for example, was reduced to 5% of total sales – total HSN sales from 10% in last year's second quarter. And more importantly, the depth of clearance markdowns were substantially reduced. Along with improved product mix, this helped drive a 6% increase in ASPs. In the second half of the year, we're focused both on reinvigorating growth in the customer base at HSN and on improving fundamentals across the business, including enhancing product freshness, balancing exposure and frequency across categories, strengthening on-air practices and getting more aggressive on driving digital engagement and sales. Speaking to product assortment. We're focused on improving both the breadth and health of the overall assortment and maintaining a fresher today's special lineup. So far, we're encouraged by the newness coming into our inventories, and we're closely tracking reorders as we move forward. This fall will be a busy time with more than 100 new brand launches scheduled over the second half of 2018. Customers will see a better balance across a variety of categories. Examples include launching Anne Klein, Clarks, Dooney & Bourke, Beekman 1802, StriVectin, MyPillow, Shark, Sleep Number, Vitamix and Keurig. Many of these brands are listed among the most desired by our HSN customers. Our recent launch of Beekman 1802 highlights the opportunity in front of us. The team did a fantastic job creating a compelling and engaging event, and the customer responded. We sold 260,000 bars of soap on the day and sold out of 177 SKUs. In both of sales dollars and units sold, Beekman set a record. No other beauty launch in the history of both HSN and QVC has achieved better results. In addition to these new brand launches, we're bringing back approximately 30 brands that have been long-time HSN customer favorites that were curtailed in recent years, including Jones New York, G by Giuliana Rancic, Born, Brookstone, Dyson, HoMedics, Sealy and Technobond. Finally, we're also launching several proprietary brands later this year developed by our Qurate design, development and sourcing team. They've had tremendous success building the strong proprietary fashion business at QVC, and we see great opportunity at HSN where the fashion category has much lower penetration. We've recently began taking inventories back up as we prepare for our upcoming brand launches. We'll also support the enhanced assortments with increased performance marketing efforts, leveraging the new house – the new in-house Qurate Retail marketing team. We believe that our strategy will ultimately drive renewed sales growth in HSN, but we remain cautious in trying to predict the timing of the turn given the likelihood of both hits and misses among so many upcoming launches. But as the success of the Beekman launch demonstrates, we are confident that as we continue to freshen the assortments and then lean in the reordering on the successes, we can get this business back to growth. So the headline on HSN is that Mike Fitzharris and his team are executing well against the priorities we laid out for you in May. The early results I've shared should indicate that we've got a good handle on the operating levers that drive profitability, and we expect continued improvement. The sales trend is challenging to turn, but we believe we're on the right path. We will take aggressive steps to make it happen. And when it does, we'll benefit from the margin improvement we're driving. We've said that it will take multiple quarters to complete the turn of HSN, but we remain confident the business will add significant value to our company. The zulily team continued its momentum and delivered another outstanding quarter. Revenue increased 13%, our third straight quarter of double-digit growth. We ended the quarter with our record-high 6.4 million active customers, reflecting our continued success investing in our marketing strategy, offering compelling events with boutique and national brands, expanding China direct shipping and enhancing the customer experience through initiatives like the rollout of our new customer returns program. Operating loss improved 7%. Adjusted OIBDA grew 12% on largely stable OIBDA margins. Sales growth and the leveraging of operating expenses was partially offset by higher SG&A expenses and a slight decrease in gross margins due to higher transportation costs. However, the hard work of the supply chain team that I mentioned last quarter is starting to show results. Gross margins, while down to last year, improved 140 basis points sequentially, and we remain confident that we'll see improving year-over-year results in the back half. Turning now to Cornerstone. Sales declined 9% primarily on continued challenges at Frontgate. Garnet Hill achieved a record Q2 financial performance and continues to demonstrate strong momentum. Ballard Designs also registered record Q2 revenue, driven primarily by strong growth in the retail and digital channels. Operating income at Frontgate declined primarily due to purchase accounting amortization. Adjusted OIBDA fell $2 million or 10%, driven by lower sales, partially offset by lower operating expenses. We strategically reduced catalog circulation as we rebalanced marketing investments across the digital and retail platforms. Frontgate remains our primary focus at Cornerstone, and we continue to make progress towards repositioning the brand and the product assortment, and we look forward to the deep experience and leadership that Tom Bazzone brings to the management team. We recently announced that we will be integrating Cornerstone's Improvements brand into HSN and closing its catalog operation by year-end. Improvements is the smallest business in the Cornerstone portfolio, not currently profitable. And ultimately, we felt that it was not a strategic fit with what we're trying to achieve with the Cornerstone brands. By integrating the Improvements into HSN, we can preserve the value we see in the line and drive sales on its strongest platform. Overall, the move is expected to reduce Cornerstone's revenue by an estimated $75 million annually, with an essentially neutral impact to overall Qurate adjusted OIBDA. In Q3, we anticipate incurring approximately $10 million of onetime costs for severance, lease liabilities associated with closing our Cleveland operation and liquidation of inventory. I want to take a moment to thank our Improvements team members for their extraordinary passion and dedication to the business and all their efforts over many years to make Improvements a special and unique brand. Looking forward, we have a firm grasp on the challenges at Cornerstone and remain confident in the growth potential of the portfolio. The team remains focused on building strong brands, developing differentiated compelling product assortments that resonate with our customers and driving sustainable growth in revenue and gross margins. In summary, our results are directionally aligned line with what we shared in May. We're past the most challenging margin comparisons and anticipate a more favorable margin profile in the back half. We're thrilled with the strong growth in new and total customers in key businesses, and we're encouraged by our progress expanding our marketing, social and digital initiatives. And we will continue to accelerate these programs as we see positive results. At our Investor Day, we articulated a multiyear view of profitable growth and enhanced free cash flow generation that we believe will drive significant value for our shareholders. The strategic progress we're making reinforces our confidence in the financial framework we've shared. And with that, I will turn it over to Mark.
