Thank you, Scott, and good morning, everyone. I will begin my remarks on our operating segment performance by highlighting the current state of the North America truckload market . On Slide 9, the light and dark blue lines represent the percent change in NAST truckload rate per mile billed to our customers and cost per mile paid to our contract carriers, net of fuel costs over the current decade. As a reminder, this Slide includes the impact of our truckload business previously reported in the Robinson Fresh segment. NAST truckload price per mile and cost per mile both declined in the quarter versus the year ago period, where both price and cost increased over 20%. We benefited from a market-based shift to contractual volume in a falling cost environment, as routing guide performance returned to a more normal depth of tender, resulting in improved truckload net revenue margin in the first quarter. And while changes in cost tend to lead changes in price, over time price and cost generally move together. One of the metrics we use to measure market conditions is the truckload routing guide depth from our Managed Services business, which represents roughly $4 billion in freight under management. In the first quarter, average routing guide depth of tender was 1.2, representing that on average the first carrier in a shipper's routing guide was executing the shipment in most cases. As John mentioned, we are seeing evidence of a softening demand and modest increase in capacity, as reflected by the reduction in price and costs shown on this Slide. We continue to set pricing that we feel best reflects the current freight market conditions, while maximizing our ability to drive net revenue growth. So with route guide depth moderating, we are adjusting our prices to reflect the current environment and to ensure we are near the top of our customer's routing guides. Moving to Slide 10, this graph shows NAST truckload average price per mile billed to customers and cost per mile paid to our carriers, net of fuel, since 2010, and represents the underlying data from the previous Slide. We have excluded the actual price per mile and cost per mile scale on this Slide to protect our proprietary information. While the absolute price per mile and cost per mile moderated versus last quarter and are below year-ago levels, they have returned to the trend line which averages about 4% annual increases in rate and cost over the current decade. Our non-asset-based business model combined with the largest network of customers and carriers in North America, gives us the flexibility to adjust our pricing in response to changing marketplace conditions. This chart highlights the strength of our business model over time and shows that we have maintained a consistent spread between price and cost, even in periods of high volatility in the freight market and periods of aggressive competitive activity. Turning to Slide 11, in our North American Surface Transportation business, first quarter NAST net revenues increased 11% to $487 million, led by double-digit growth in truckload. Our first quarter results also included volume growth in both truckload and LTL service lines and growth in market share, when compared to year-over-year changes in the Cash Freight Index. A shift in our business mix toward contractual freight in a falling cost environment drove a 230 basis point expansion in first quarter NAST net revenue margin. Truckload net revenues increased 14.7% to $359 million in the quarter, driven by the margin expansion we typically see as we transition to a more balanced freight market. Our shift toward contractual volume resulted in approximate mix of 65% contractual and 35% transactional volume in the quarter versus the 55%, 45% mix in the year ago period. Our first quarter results include the impact of reprising activity to reflect current market conditions, including modest price declines in contractual awards with several of our customers. First quarter NAST truckload volumes increased 0.5% versus last year, and increased 2% on a per business day basis. This volume growth includes the impact of approximately 60% reduction in our negative loads associated with contractual shipments. Profitable volume for NAST increased at a mid-single-digit rate for the quarter. We continue to add new carriers to our network, driving further expansion of the largest fleet of motor carriers in North America. We added approximately 5,000 new carriers in the first quarter, a 19% increase over last year's first quarter. Carriers are increasingly relying on C.H. Robinson to provide freight that enables them to be successful business owners. This also allows us to provide our customers with additional capacity solutions that help them more effectively execute their supply chains. First quarter LTL net revenues increased 3.6% to $115 million, led by growth in our consolidation and temperature controlled LTL businesses. Despite weather disruptions in the Midwest and one less business day, we were able to deliver 1% volume growth in the quarter. We expect our LTL volume growth to accelerate in the second quarter as we continue to add new customers and renew awards with existing customers. In our intermodal service line, net revenues decreased 3.9% in the quarter. Intermodal volumes declined 33% as a combination of lane reductions related to precision scheduled railroading and a decline in truckload pricing drove an industry shift from intermodal to truckload. This decline in volume was largely offset by higher pricing and a change in customer mix for the quarter. Slide 12 outlines our NAST operating income performance. First quarter operating income increased 17.6% to $211 million. Operating margin of 43.4% improved 240 basis points, driven by the combination of double-digit net revenue growth and a modest increase in headcount in the quarter. This strong operating performance reflects the benefits of our continued investments in technology. Our investments in artificial intelligence and machine learning are providing expanded capabilities and insights to our customers and our carriers. Our advanced algorithms and data advantage are further improving the ability for our employees to profitably match shipper demand and carrier supply and increasing the level of automated interactions across our network. These technology investments have helped us generate four consecutive quarters of year-over-year operating margin expansion in our NAST business. Over the balance of 2019 and beyond we'll continue to accelerate our digital transformation efforts to provide benefits to our network of customers and carriers and to drive process efficiency for our employees. We expect that our NAST headcount will be flat to down slightly for the year. Turning to Slide 13, and our Global Forwarding business, first quarter Global Forwarding net revenues increased 3.4% to $127 million. In our ocean service line, net revenues increased 4% for the quarter, mostly driven by margin expansion. Ocean volumes were flat in the quarter. First quarter air net revenues increased 0.4%, as margin expansion was largely offset by a 4% decline in shipments. We believe that our first quarter volume performance in ocean and air was negatively impacted by increased shipments in the fourth quarter of 2018, as many of our customers worked to build inventory ahead of anticipated tariffs enacted in the first quarter of 2019. Customs net revenues increased 5.9% for the first quarter, driven by customs transaction growth of 2.5%, as we continue to expand our customs presence around the world. Our first quarter also includes one month of results from our acquisition of The Space Cargo Group, a leading provider of international freight forwarding, customs brokerage and other logistics services in Spain and Colombia. We have an extensive operating history with Space Cargo as our agent in Spain, and we feel great about the cultural compatibility and the talented team that we have brought on to Robinson. The integration is off to a great start. As the acquisition closed on February 28th, Space Cargo's results did not have a material impact on our overall Global Forwarding or Enterprise results for the quarter. In our conversations with our global customers, these companies are continuing to plan for tariff activity and potential implications and the redesign of global supply chains. We are actively engaged with our Global Forwarding customers to help them understand and quantify the impacts of the changing tariff landscape. We are benefiting from our strong presence in Southeast Asia, where first quarter net revenues grew well ahead of our total service line growth for both ocean and air. Given our broad portfolio of service offerings, we continue to believe that we are well positioned to help our customers win in an ever-changing global trade environment. Slide 14 outlines our Global Forwarding operating income performance. First quarter operating income increased 72.8% to $14 million, operating margin of 11.2% increased 450 basis points versus last year, driven by higher net revenues and a 1.3% decline in average headcount. As a reminder, the first quarter is typically our smallest net revenue quarter for the year, so our first quarter operating margin is typically well below the average for the year. We continue to see significant opportunities to drive scale and geographic reach in our Global Forwarding business. At the same time, we will increase our level of technology deployment to make our processes more efficient. Moving forward, we expect to deliver operating margin expansion through a combination of volume growth that exceeds headcount growth and investments in technology to drive operating cost efficiency. Over the long-term, we remain confident that we will deliver operating margin performance, consistent with other leading companies in the global forwarding segment. Moving to our All Other and Corporate businesses on Slide 15. As a reminder, All Other now includes Robinson Fresh, Managed Services, surface transportation outside of North America, other miscellaneous revenues and unallocated corporate expenses. First quarter Robinson Fresh net revenues were $29 million, down 5% from last year. Case volumes declined 7%, primarily driven by weather related crop reductions. Managed Services' net revenues increased 10.9% to $20 million in the quarter, driven by a combination of selling additional services to existing customers and new customer wins. Customers continue to value our transportation management system offering, which allows them to manage their carrier selection process in complex supply chains without the required fixed investment in people or technology. We have got a strong pipeline of new business opportunities in our Managed Service business and we expect continued net revenue growth as we move through the year. Other Surface Transportation net revenues increased 0.7% in the quarter to $16 million, primarily driven by mid single-digit volume growth in European truckload. During the first quarter, we were able to deliver market share gains in NAST truckload and LTL, double-digit net revenue growth on a per day basis and net revenue margin and operating margin expansion in excess of 200 basis points. We also generated over $250 million in cash flow from operations and increased our returns to shareholders. These strong results reflect the continued ability of our employees to successfully navigate an ever-changing marketplace where both market dynamics in the competitive landscape continues to evolve at a rapid pace. Our people are focused on creating unique value for our network of customers and carriers and keeping them at the center of our focus. Because of this focus on accelerating commerce for the companies that engage on our platform, we continue to win in the marketplace. To ensure we deliver continued strong financial performance moving forward, we remain committed to three core objectives. First, we are committed to taking market share. Over time, we have taken market share in each of our largest service lines and we expect to continue to expand our market share gains in 2019 and beyond. Second, we'll continue to automate our core processes and reduce our cost to sell and cost to serve, while also providing excellent service to our customers and our carriers. And third we are intently focused on improving operating leverage across our businesses. We remain committed to the long-term targets we shared at our Investor Day in 2017. Over time, we expect to deliver annual net revenue growth of 5% to 10%, with operating income growth that exceeds net revenue growth. We are firmly committed to operating margin expansion and believe our continued investments in technology and process automation will help us to achieve this objective. We are also committed to strong cash returns to shareholders and expect to deliver annual double-digit growth in earnings per share over time. Moving forward, I'm confident that we'll continue to deliver industry-leading capabilities and solutions to the over 200,000 companies that conduct business on our global platform. I'm also confident that we'll continue to provide rewarding career opportunities for our employees and generate strong returns for our shareholders. Thanks for listening this morning. Before I turn the call back to John, for the last time, I wanted to take a moment in this forum and thank John for his leadership of this great organization over the past 17 years. Under John's leadership, C.H Robinson has evolved from a leading US truck brokerage and produce Company to a global supply chain Company, powered by people, process and technology. Together under John's leadership, our team has created tremendous value for our customers, our carriers and our shareholders, while providing opportunities for all of our employees around the globe to learn, to grow and to serve. On behalf of all the 15,000 people around the globe, I want to say, thanks for all you have done John. I'm honored and excited to lead Robinson into the next chapter with your support as Executive Chairman and to build upon our strong foundation of success. And with that, I will turn it back to John.
