Thank you, Eric, and good morning everyone. Earlier today we announced 2020 fourth quarter earnings of $0.37 per share. The quarter's results were impacted by the COVID-19 pandemic, which reduced demand for Kirby's products and services, particularly in Marine Transportation, where we experienced low volumes and continued poor market dynamics and poor barge utilization. Across the company, we have tightly managed costs, which has helped maintain overall Marine Transportation margins near 10%, and distribution and service margins near breakeven. Our fourth quarter earnings also included a tax benefit as a result of the CARES Act, which Bill will discuss in a few minutes. Looking at our segments, in Marine Transportation, the inland and coastal markets experienced challenging market conditions, with low demand particularly for the transportation of refined products, crude oil, and black oil. Although the economy showed some modest signs of improvement during the quarter, increasing cases of COVID-19, high product inventories, and impacts from two Gulf Coast hurricanes contributed to a slight sequential decline in quarterly average refinery utilization. During the quarter, refinery utilization averaged 77%, compared to a previous five-year fourth quarter average of 90%, and it ended the quarter at 80%. Chemical plant utilization modestly improved 1% sequentially, but remained below 2019 levels. Overall, for our inland and coastal businesses there were minimal spot requirements, low barge utilization, and additional pricing pressures throughout the quarter. In Distribution and Services, fourth quarter revenues sequentially improved, benefiting from the continued economic recovery, higher product sales in commercial and industrial, and some pickup in activity in oil and gas distribution. In the commercial and industrial markets, we experienced increased demand for parts and service in the on-highway and power generation businesses, higher product sales in Thermo King, and increased deliveries of new marine engines. These gains were partially offset however by normal seasonality, including lower utilization in power generation rental fleet following the hurricane season, as well as reduced major overhauls in marine repair during the harvest in the dry cargo market. In the oil and gas market activity continued to recover as many E&Ps modestly increased spending during the fourth quarter, and well completion activity improved. Active frac crews, which bottomed around 50 in the second quarter, improved every month during the fourth quarter, and finished the year in excess of 150. This activity improvement contributed to higher demand for new transmissions, parts, and service in our distribution businesses. In manufacturing, remanufacturing activity was steady, and we received additional new order for environmental-friendly fracturing equipment. In a few moments I'll talk about our outlook for 2021, but before I do I'll turn the call over to Bill to discuss our fourth quarter segment results and the balance sheet.
