Thank you, J.C. I'll start with the consolidated quarter results and then provide additional detail at the segment level. On a consolidated basis, our first quarter operating profit improved 9.9% to $8.3 million, up from $7.6 million in 2020 driven by substantially higher earnings at our Coal Mining segment. This improvement was partly offset by lower earnings at our North American Mining segment and an increase in unallocated employee-related expenses. Our consolidated net income also increased significantly, up 45.3% to $9 million or $1.25 per share from $6.2 million or $0.88 per share last year. The improved operating profit as well as favorable changes in the market value of equity securities, which are reported in other income, drove the significant improvement in net income. Before I discuss the segments, I wanted to mentioned that addition - in addition to reporting consolidated EBITDA, we started reporting and discussing segment EBITDA this quarter, given the significant impact of depreciation expense in our results without providing the consolidated EBITDA and segment EBITDA would help everyone better understand the underlying results from business operations. At our Coal Mining segment, operating profit and segment EBITDA increased primarily because of substantially higher results at Mississippi Lignite Mining Company due to an increase in customer demand. This increase in demand contributed to a reduction in the cost per ton of coal and an overall increase in the profit per ton delivered. The improvement in the Coal Mining segment's operating profit was partly offset by a decrease in earnings of unconsolidated operations and higher operating expenses, primarily an increase in insurance expense partially offset by lower employee-related costs. And North American Mining's first quarter 2021 operating profit decreased from the prior year, primarily as a result of higher employee-related costs and lower earnings related to the Thacker Pass Project. Segment EBITDA also decreased but to a lesser extent than operating profit as depreciation expense increased over the prior year first quarter given more equipment being placed in service to support activities related to newer contracts. At the Minerals Management segment, operating profit and segment EBITDA generally comparable to the prior year as the increase in revenue was offset by higher employee-related expenses. Those are the significant factors affecting the first 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 customer requirements. However, operating profit in 2021 is expected to decrease compared with the prior year when you exclude prior year charges of $4.6 million related to an asset impairment and inventory write-down and our voluntary separation program. The decrease in operating profit is primarily attributable to substantially lower full year earnings expected at Mississippi Lignite Mining Company and reduced earnings at the unconsolidated Coal Mining operations. A decrease in employee-related costs resulting from lower headcount primarily from our 2020 voluntary separation program is expected to be partially offset by higher insurance expense. In addition, our Coal Mining segment EBITDA is expected to increase moderately over the prior year, excluding the $1.1 million asset impairment charge recognized in 2020. At North American Mining, we expect an increase in tons delivered, operating profit and segment EBITDA for the 2021 full year over last year as a result of increased production under existing contracts and contributions from new mining contracts. The increase in operating profit is expected to be partially offset by an increase in operating expenses, primarily due to higher employee-related costs. At our Minerals Management segment, we expect full-year operating profit and segment EBITDA to decrease moderately from 2020, excluding the impact of $7.3 million of impairment charges taken last year and an income - and any income related to asset acquisitions made after March 31, 2021, including the ones J.C. discussed. An anticipated reduction in royalty income from existing Ohio mineral and royalty assets is expected to be partially offset by royalty income generated from the Permian Basin mineral interests acquired in 2020. Taking into the - into account the transactions entered into early in the second quarter, Minerals Management is targeting an additional $5 million of investments in mineral and royalty interests during the remainder of 2021. On a consolidated basis, excluding the prior year charges previously mentioned, as well as the favorable impact of additional business development activity, we expect substantially lower net income as a result of lower operating profit and anticipated increase in interest expense and a reduction in interest income. Consolidated EBITDA in 2021 is expected to increase moderately over 2020 adjusted for prior year asset impairment charges. We also expect the tax benefit rate between 3% to 5% this year. Moving away from results and expectations, let me briefly move to cash flow information. We ended the quarter with consolidated cash of $79.1 million and debt of $44.4 million compared with consolidated cash of $88.5 million and debt of $46.5 million at the end of the year. In addition, we had availability of $119 million under our $150 million revolving credit facility. We believe that a conservative capital structure and adequate liquidity are important given evolving trends in energy markets and our strategic initiatives to grow and diversify. Last year, our cash flow before financing activities included a significant use of cash. In 2021, we are anticipating positive cash flow before financing activities. Now, let me open up the call for your questions.
