Thank you, Judy, and good morning, everyone. Let me begin with some consolidated information. Fourth quarter 2018 consolidated revenues were $774 million compared to $711 million in last year's fourth quarter, a per day increase of 8.9%. On a GAAP basis, we had fourth quarter 2018 net income of $0.57 per diluted share compared to the $1.37 per share last year. As detailed in the GAAP to non-GAAP reconciliation table in yesterday afternoon's earnings press release, adjusted fourth quarter 2018 net income was $1.01 per diluted share compared to the $0.42 in the same period of 2017. ArcBest's fourth quarter 2018 effective GAAP tax rate was 26%, which was comparable to the fourth quarter tax rate on a non-GAAP basis. For the full year of 2018, consolidated revenues totaled $3.1 billion compared to $2.8 billion in 2017, a per day increase of 9.3%. Full year earnings per diluted share were $2.51 compared to $2.51 compared to $2.25 in 2017. On a non-GAAP adjusted basis, as outlined in our earnings press release, 2018 earnings were $3.86 per diluted share compared to the $1.34 in 2017. In 2018 total net capital expenditures, including equipment financed, equaled $134 million, which was below previous expectations reflecting shifts in the timings of some expenditures into 2019. 2018 revenue equipment totaled 90 million, the majority of which was for ArcBest's Asset-Based operation. Depreciation and amortization costs on property, plant and equipment were $104 million. In addition, amortization of intangibles assets was $4.5 million in 2018. For 2019, total net capital expenditures are estimated to range from $170 million to $180 million. This includes revenue equipment purchases of approximately $90 million, primarily replacements for ArcBest's Asset-Based operation. The increase in the 2019 capital expenditure estimate is primarily associated with real estate projects, dock equipment, including forklifts and technology investments. ArcBest's depreciation and amortization costs on property, plant and equipment for 2019 are estimated to range from $110 million to $115 million. This expense range does not include amortization of intangible assets, which were estimated to be approximately $4.5 million in 2019. For full year of 2018, GAAP was 20.3%. The effective tax rate reconciliation table on Page 10 of our earnings press release shows the reconciliation of GAAP to non-GAAP effective tax rate, which was 26.5% in 2015. We currently expect our full year 2019 non-GAAP tax to be approximately 27%, while the effective rate in the quarter may be impacted by items discrete to that period. We ended the fourth quarter with unrestricted cash and short-term investments of $297 million. Combined with the available resources under our credit revolver and our receivable securitization agreement, our total liquidity currently equals $495 million. Our total debt at the end of 2018 of $292 million includes the $70 million balance on our credit revolver, the $40 million borrowed on our receivable securitization and $182 million of notes payable, primarily on equipment for Asset-Based operation. The composite interest rate on all of our debt is 3.4%. Full details of our GAAP cash flow are included in our earnings press release. As previously disclosed, technology investments have been made in ArcBest technology is in a variety of areas to improve our customer experience and also optimize our operating segments. For example, in the Asset-Based segment, we have described work to improve city pickup and delivery productivity with enhanced tools such as barcoding, tablets and scanning equipment. In the ArcBest Asset-Light segment, common coding systems and predictive analytics tools are currently in use and undergoing continuous development, all of which require ongoing investments. ArcBest technologies serves as an incubator for the initial phases of technology development. Once a level of success is demonstrated, these initiatives may be transitioned into the field and operating segments for more extensive and live testing feedback in an ongoing development. As a result, we expect that our Asset-Based business will incur additional cost of approximately $10 million during 2019. We estimate the cost impact to increase throughout the year, with approximately $1.5 million estimated in first quarter of 2019. Such investments are important for us to continue meeting and exceeding our customers' expectations in a rapidly evolving market place. If successful, we expect there would be some future benefits for the broader application of these initiatives in our business. Asset-Based fourth quarter revenue was $549 million, an increase of 10.4% compared to last year. Asset-Based quarterly tonnage per day increased 2.8% versus last year's fourth quarter. And for fourth quarter 2018 by month, Asset-Based daily total tonnage versus the same period last year increased by 2.3% in October, increased by 2.8% in November and increased by 3.3% in December. As Judy mentioned earlier, these total tonnage figures included the impacts of solid LTL-rated tonnage gains as monthly increases were in the upper single-digit-percentage range throughout the quarter. Truckload rated shipments in the ABF Asset-Based network were below the prior year by more than 10% in each months of the fourth quarter as availability of these shipments at acceptable price levels was more limited. In addition with the growth we have been experiencing in our LTL-rated business, we're utilizing more of our available equipment and workforce capacity to serve the needs of our customers with LTL needs. Fourth quarter total shipments per day increased by 4.2% compared to last year's fourth quarter. This was the first quarter of 2018 that our average daily shipment count increased versus the same period last year. Fourth quarter total billed revenue per hundredweight on Asset-Based shipments was $34.90, an increase of 7.9% compared to the fourth quarter of last year. Excluding fuel surcharge, the increase in fourth quarter billed revenue per hundredweight on Asset-Based LTL-rated freight was in the mid-single digits. We secured an average 4.6% increase on Asset-Based customer contract renewals and deferred pricing agreements negotiated during the quarter. As we look ahead to 2019, we will continue to focus on maintaining acceptable pricing levels across the Asset-Based account group. Earlier, Judy mentioned, next week's Asset-Based general rate increase whose timing illustrates our continued emphasis on yield improvement and our belief that the pricing environment is healthy. This year, as we compare back to 2018 when quarterly year-over-year yield increases range between 8% and 10%, we expect our average price increase percentages to return to more normal levels in 2019. On an adjusted basis, our Asset-Based fourth quarter operating ratio was 93.3% compared to 96.1% in 2017. For the full year of 2018, ArcBest's Asset-Based revenue was $2.2 billion compared to $2.0 billion in 2017, a per day increase of 8.9%. Asset-Based 2018 total tonnage per day was flat compared to the previous year of daily shipments decreased by 3.3%, resulting in a 3.3% increase in total pounds per shipment. On an adjusted basis, our Asset-Based full year operating ratio was 93.5% compared to 97.1% in 2017. In total, the average daily revenue in ArcBest's Asset-Light businesses increased 10% over last year's fourth quarter, reflecting revenue growth in both the ArcBest segment and the FleetNet segment. On an adjusted basis, fourth quarter Asset-Light operating income was $7.8 million compared to $5.5 million last year. Full year 2018 revenue for the Asset-Light businesses was $976 million compared to $863 million in 2017, a daily increase of 12.9%. Full year 2018 adjusted operating income for these businesses was $26.5 million compared to $23.7 million in 2017. Adjusted full year 2018 Asset-Light EBITDA was $43.4 million compared to adjusted EBITDA of $38.1 million in 2017. Yesterday afternoon, we filed an 8-K that included our fourth quarter of 2018 earnings release, along with an exhibit that provided some additional information about our current quarterly financial results, along with our recent business levels and our future expectations on certain financial metrics. This information should be helpful in modeling our expectations for 2019 financial results. Now I'll turn it over to Judy for some closing comments.
