Thank you, J.C. I'll start with the consolidated quarter and full year results and then provide additional detail at the segment level. As J.C. mentioned, we faced many challenges in 2020, which culminated in disappointing fourth quarter and full year results. For the fourth quarter, we reported a consolidated operating loss of $8 million and a net loss of $5.4 million or $0.77 per share. There were $9.8 million of charges taken during the 2020 fourth quarter, which I will cover in more detail in the individual segments that contributed to the losses in the quarter. For the 2020 full year, we reported consolidated operating profit of $13.4 million and net income of $14.8 million or $2.10 per diluted share, and that compared with consolidated operating profit of $38.8 million and net income of $39.6 million or $5.66 per share for the 2019 full year. Now, let me provide a bit more detail on certain segment results. In the 2020 fourth quarter, the Coal Mining segment had an operating loss of $400,000 compared with operating profit of $6.4 million in the 2019 fourth quarter. The current year operating loss includes the following: a noncash charge of $2 million for the write-down of Mississippi Lignite Mining Company's coal inventory to net realizable value, a $1.5 million charge for costs associated with our voluntary separation program implemented in the fourth quarter of 2020 and a $1.1 million noncash asset impairment charge for a legacy database acquired in the 1990s with information on coal reserves. If we exclude these charges, the Coal Mining segment's operating profit still declined from last year's fourth quarter, primarily because of substantially lower results at Mississippi Lignite Mining Company resulting from a reduction in tons delivered during the fourth quarter. This reduction in tons contributed to an increase in the cost per ton delivered. Also contributing to the lower operating results were additional wind-down costs at Camino Real Fuels, not covered by Camino's former customer, higher operating expenses and reduced earnings of unconsolidated operations. The Minerals Management segment reported an operating loss in 2020 compared with operating profit in 2019, despite an increase in fourth quarter 2020 revenues. During the fourth quarter, we wrote off $6.7 million of capitalized leasehold costs and prepaid royalties on legacy coal reserves where prospects for development deteriorated in 2020. Excluding the asset impairment charge, the 2020 fourth quarter operating results in the Minerals Management segment increased over the 2019 fourth quarter, primarily because of new Ohio natural gas wells and an increase in natural gas prices. Those are the significant factors affecting the fourth quarter results. Now, let me turn to our outlook. In the Coal Mining segment, we expect 2021 coal deliveries to be comparable to 2020 based on current expectations of current customer requirements. However, the Coal Mining segment's 2021 operating profit is expected to decrease significantly from 2020. This decrease is primarily because of substantially lower earnings expected at Mississippi Lignite Mining Company and a reduction in earnings at the unconsolidated coal mining operations. The lower Mississippi Lignite Mining Company results are because of an anticipated increase in the cost per ton of coal delivered in 2021 compared with last year, due in part to an increase in depreciation expense associated with development of a new mine area. The anticipated reduction in earnings at the unconsolidated coal mining operations is expected to be mainly driven by a reduction in fee-based earnings at the Liberty Mine as the scope of final mine reclamation activities there have been reduced. This lower operating profit is expected to be partially offset by a decrease in operating expenses, primarily due to lower employee-related costs resulting from the 2020 voluntary separation program, partially offset by higher insurance expense. In 2021, we expect North American Mining's operating profit to increase moderately over this year with its existing customer contracts. However, we are pursuing a number of growth initiatives that, if successful, would be accretive to future earnings. In addition, I would like to highlight that in January of this year, the Thacker Pass project received a Record of Decision from the U.S. Bureau of Land Management, following the completion of the National Environmental Policy Act Process. This decision represents an important milestone in the development and the permitting of the Thacker Pass project and more permitting decisions are expected later in 2021 with production expected to begin in the second half of 2022. Excluding the impact of the $6.7 million write-off taken in 2020, we expect Minerals Management operating profit to be down substantially in 2021 from 2020. This decrease is primarily related to a reduction in royalty income from existing Ohio mineral and royalty assets as a result of expected lower natural gas prices, fewer expected new wells in Ohio, lower commodity prices and the natural production decline that occurs early in the life of a well. Let me spend a minute talking about our investment plans for Minerals Management. As J.C. mentioned, we acquired approximately $40 million of mineral assets in 2020, and we are targeting an additional $10 million in investments this year. While we expect these investments to be accretive to earnings, each investment's contribution will be dependent on the timing, size and stage of mineral development of the reserves acquired. On a consolidated basis, excluding the favorable impact of potential business development activities, we expect substantially lower 2021 pretax earnings as a result of lower consolidated operating profit, an anticipated increase in interest expense and a reduction in interest income. These lower pretax results are expected to be partially offset by an increase in the benefit from income taxes, primarily due to a benefit from percentage depletion at certain mining operations. Consolidated pretax income and net income are expected to be higher in the second half of 2020 than in the first half of 2021, primarily due to current expectations on the timing of customer requirements in the Coal Mining segment. Overall, while we expect consolidated net income this year to decrease significantly from last year, as J.C. mentioned, we will still continue to view the long -- we still continue to view the long-term business outlook positively because of the strong pipeline of potential new projects. The COVID-19 pandemic closed certain business development initiatives in 2020, but the outlook for growth in the North American Mining and Minerals Management segment and in our Mitigation Resources of North America business remains strong. In addition, the voluntary separation program that occurred in the fourth quarter was substantially completed by the end of the year. As a result of this program, we are expecting estimated net benefits of between $1.5 million and $2.5 million annually beginning in 2021. Moving away from results, let me briefly provide some cash flow information. We ended the year with consolidated cash of $88.5 million and debt of $46.5 million compared with consolidated cash of $97.6 million and debt of $23.1 million at the end of the third quarter. In addition, at the end of the year, we had availability of $117 million under our $150 million revolving credit facility. We believe that a conservative capital structure and liquidity are important given our strategic initiatives to grow and diversify as well as the changing trends occurring in energy markets. That said, our cash flow before financing activities varies with changes in customer demand, particularly in the Coal Mining segment as well as changes in earnings of the Minerals Management segment, working capital changes, capital expenditures, investments and royalty and mineral interest as well as changes in income taxes and other factors. For the 2020 full year, NACCO's consolidated cash flow before financing activities was a use of cash of $48.5 million and included a significant use of cash related to working capital, capital expenditures and the acquisition of mineral royalty interest. We are anticipating positive cash flow before financing this year, but at a level still below the cash we generated back in 2019. Now, let me open up the call for your questions.
