Thank you, Bill. Good morning, and welcome to Landstar's 2023 first quarter earnings conference call. Before we begin, let me read the following statement. The following is a safe harbor statement under the Private Securities Litigation Reform Act of 1995. Statements made during this conference call that are not based on historical facts are forward-looking statements. During this conference call, we may make statements that contain forward-looking information that relates to Landstar's business objectives, plans, strategies and expectations. Such information, by nature, is subject to uncertainties and risks included, but not limited to, the operational, financial and legal risk detailed in Landstar's Form 10-K for the 2022 fiscal year described in the section Risk Factors and other SEC filings from time to time. These risks and uncertainties could cause actual results or events to differ materially from historical results or those anticipated. Investors should not place undue reliance on such forward-looking information, and Landstar undertakes no obligation to publicly update or revise any forward-looking information. Given the current freight environment with soft demand and readily available truck capacity, Landstar performed relatively well in the 2023 first quarter. Heading into the 2023 first quarter, demand for truck transportation services was somewhat soft. In addition, Landstar was faced with probably the most challenging quarterly financial comparison in its history. Landstar's 2022 first quarter was not only our best ever first quarter performance, but the best quarterly financial performance for any quarter in the company's history. Prior to 2022, the 2021 first quarter established a new all-time record for first quarter revenue at Landstar. 2022 first quarter revenue exceeded the '21 first quarter by 53%, growing by over $683 million. In fact, net income and diluted earnings per share each established new all-time Landstar quarterly records in the 2022 first quarter that remain unbroken today. In contrast, the freight environment was dramatically different in the 2023 first quarter. Looking back at the 2022 first quarter, consumer demand was very strong and supply chain disruption was at its peak. Those conditions resulted in a lack of available truck capacity, driving truck transportation pricing to all-time highs. Following the 2022 first quarter, demand began to soften as supply chain bottlenecks began to clear. Beginning in the summer of '22 and carrying through today, we are clearly in a different freight environment. Truck capacity is more readily available with market conditions currently favoring the shipper. As it relates to Landstar's 2023 first quarter performance, our results were generally in line with what we expected. Our first quarter guidance calls for the number of truckloads hauled via truck to be below the 2022 first quarter in the 10% to 12% range and overall revenue per truckload to be below the 2022 first quarter in a range of 15% to 17%. The actual number of loads hauled via truck in the 2023 first quarter was 12% below the 2022 first quarter at the low end of the truckload volume guidance. Actual revenue per truckload in the 2023 first quarter was 14% below the 2022 first quarter, slightly better than the high end of the truck revenue per load guidance. The slightly favorable variance on revenue per truck load compared to guidance was mostly driven by a higher-than-anticipated revenue per truckload in January, offset by lower-than-anticipated revenue per truckload in February. March came in near our expectations. In the first several weeks of April, truck revenue per load is trending slightly below normal sequential month-to-month trends. As to our air, ocean and rail intermodal transportation services, 2023 first quarter revenue was $108 million or 55% below the 2022 first quarter. The significant decrease in this non-truck transportation revenue was in line with our expectations of lower volumes across all the other modes and the expectation of a significant decrease in ocean revenue per shipment. The decrease in revenue of our non-truck transportation services was mostly due to a 48% decrease in ocean revenue per shipment, and lower volume of 39%, 32% and 9% in rail, ocean and air services, respectively. With respect to conditions in different parts of the truckload market, as mentioned in the earnings release, revenue on unsided/platform equipment held up considerably better than revenue hauled via van equipment and other truck transportation services. The quarter over prior year quarter revenue comparison for van were much more challenging than those for revenue on unsided/platform equipment. Revenue on van equipment in the 2022 first quarter crushed all-time first quarter records for van loadings and revenue per load. Revenue hauled via unsided/platform equipment, although also still strong in the 2022 first quarter by historical standards, was less impacted by peak supply chain disruption and heightened consumer demand. One metric we follow is revenue per mile on loads hauled by BCO trucks, which tends to be a more pure indicator of pricing, as this data excludes fuel surcharges billed to customers that are paid 100% to the BCO. Revenue per mile on van equipment hauled by BCOs in the 2023 first quarter was 26% below the 2022 first quarter. In contrast, revenue per mile on unsided/platform equipment hauled by BCOs in the 2023 first quarter was only 6% below the 2022 first quarter. It should also be noted that although the market has softened significantly from a year ago, Landstar revenue per mile on BCO van and unsided/platform equipment both remain above the pre-pandemic 2020 first quarter by approximately 30%. I believe the rates will remain higher than pre-pandemic levels given the significant amount of additional cost pressure to operate a truck today as compared to 3 years ago. Turning to volume. Total loadings on all modes in the 2023 first quarter were almost 13% below the 2022 first quarter. Loadings in our top 25 commodity categories, which make up about 70% of our load volume, were down a combined 10% compared to the 2022 first quarter. From the 2022 first quarter to the 2023 first quarter, total loadings of consumer durables decreased 11%. Automotive equipment and parts decreased 15%, hazardous materials decreased 4% and building products decreased 16%, while machinery increased 2%. Landstar is known throughout our industry as a key truck capacity provider to other trucking companies, 3PLs and truck brokers. During periods of tight truck capacity, those entities reach out to Landstar to provide truck capacity more often than during times more readily available truck capacity. The freight hauled by Landstar on behalf of other truck transportation companies includes almost all our commodity group base, including our substitute line haul service offering. Substitute line haul loadings was one of our strongest commodity performance throughout the pandemic. However, load volume for this service offering varies significantly based on domestic consumer demand and decreased 60% in the 2023 first quarter from the 2022 first quarter. Overall, revenue hauled on behalf of other truck transportation companies in 2023 first quarter was 47% below the 2022 first quarter, a clear indicator in our model, the capacity is more readily accessible. Revenue hauled on behalf of other truck transition companies was 18% and 24% of revenue in the 2023 and 2022 first quarters, respectively. Our business remains highly diversified with over 25,000 customers, none of which contributed over 4% of our revenue in the 2023 first quarter. The decrease in truckload volume we experienced quarter over prior year quarter was primarily driven by changes in the overall freight environment rather than the loss of any major accounts. During the 2023 first quarter, BCO truck count decreased by 472 trucks and has decreased approximately 9% versus this time last year. Historically, Landstar has experienced increased turnover in BCO truck count when truck rates decreased. Over the past 12 months, truckload rates decreased at the most rapid pace in recent years. The largest truckload rate decrease was with respect to services provided on van equipment, which is a primary equipment type hauled by BCOs. BCO turnup has also been influenced by a significant increase in the cost of repairs and extended period of time trucks are out of service awaiting parts. The ability to get back on the road is also impacted by the high cost of used trucks, which impacts the potential for BCO to trade their existing used truck for a newer used truck that may be less subject to unscheduled maintenance issue and unforced downtime. I will now pass to Jim Todd to comment on other additional P&L metrics regarding the 2023 first quarter performance.
