Thank you very much. Good morning, everyone, and welcome to our 2019 fourth quarter and full year earnings call. I am Christina Kmetko, and I'm responsible for Investor Relations at NACCO Industries. I will be providing a brief overview of our quarterly results and business outlook, and then I will open up the call for your questions. Joining me today are J.C. Butler, President and Chief Executive Officer of both NACCO and North American Coal; and Elizabeth Loveman, NACCO's Vice President and Controller. Yesterday, we published our fourth quarter and full year 2019 results and filed our 10-K. Copies of our earnings release and 10-K are available on our website. For anyone who is not able to listen to today's entire call, an archived version of this webcast will be on our website later this afternoon and available for approximately 12 months. As we begin, I would like to remind participants that this conference call may contain certain forward-looking statements. These statements are subject to a number of risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements made here today in either our prepared remarks or during the following question-and-answer session. We disclaim any obligation to update these forward-looking statements, which may not be updated until our next quarterly conference call, if at all. Additional information regarding these risks and uncertainties was set forth in our earnings release and in our 10-K. Now let me discuss our 2019 results. I will cover our consolidated results first and then provide the highlights for each segment. On a consolidated basis, while our full year 2019 net income solidly increased, rising to $39.6 million from $34.8 million last year, our quarter did not fare as well. Our fourth quarter consolidated net income decreased to $6.4 million or $0.91 per share from $11 million or $1.57 per share last year. There are a number of contributing factors to this decline, which are best explained by segment. In our Coal Mining segment, operating profit decreased substantially from the prior year fourth quarter primarily driven by Centennial Natural Resources and Mississippi Lignite Mining Company. At Centennial Natural Resources, we recorded a $2 million unfavorable adjustment to mine reclamation liabilities in the 2019 fourth quarter, whereas last year, we recorded a favorable $1.8 million adjustment. In Mississippi Lignite Mining Company, there were fewer deliveries in the fourth quarter of 2019 and in 2018 because of a decrease in the number of days the customer's power plant was dispatched. Also, the prior year fourth quarter results included a favorable $3 million contractual settlement that did not reoccur in 2019. These items, as well as a decrease in earnings at our unconsolidated operations because of fewer tons delivered, drove the significant decrease in the coal segment's operating profit. As discussed in our release, the Minerals Management segment and, to a lesser extent, the North American Mining segment also had reduced operating profit. A tax benefit on the quarter's earnings partly offset the reduced fourth quarter operating profit, but taxes are better understood on a full year basis. Our effective income tax rate for the 2019 full year was 8.7% compared with 17.5% in 2018. The 2019 effective income tax rate included a $2.5 million tax benefit, which resulted primarily from changes in prior year estimates and the settlement of certain tax items from ongoing examinations. The 2018 effective income tax rate included $1.2 million of tax expense from the recording of an additional valuation allowance. If you exclude these items, our effective income tax rate would have been approximately 14.5% for 2019 and 14.7% last year. Those are the significant factors affecting the fourth quarter results. Now let me turn to our outlook. At the Coal Mining segment, we expect overall deliveries to increase modestly over 2019 at both the consolidated and unconsolidated operations because of an anticipated increase in customer requirements. Our customers are forecasting a reduction in planned power plant outage days and an increase in the number of days dispatched this coming year. We expect 2020 Coal Mining operating profit to increase over 2019. This anticipated increase is primarily the result of an expected increase in gross profit at Mississippi Lignite Mining Company and the absence of the $2 million unfavorable adjustment to mine reclamation liabilities that was taken in the fourth quarter of 2019. We also expect a modest improvement in earnings at our unconsolidated coal mining operations. These improvements are anticipated to be partly offset by an increase in operating expenses from anticipated higher professional fees and IT expenses. In the Coal Mining segment, capital expenditures are expected to be approximately $24 million in 2020. We expect elevated levels of capital expenditures through 2021 primarily because of spending at Mississippi Lignite Mining Company associated with the development of a new mine area. At our North American Mining segment, we anticipate limestone deliveries to increase and full year operating results to improve significantly over 2019 as results are expected to benefit from earnings associated with new limestone mining contracts. We expect the improvement in operating profit to be partly offset by an increase in operating expenses because of higher employee-related costs associated with the new mining operations. We expect capital expenditures in North America Mining to be $9 million in 2020. These expenditures are primarily for the acquisition, relocation and refurbishment of draglines. Our Minerals Management experienced a significant increase in royalty income in 2019 compared with 2018 primarily because of a significant increase in the number of gas wells operated by third parties to extract natural gas from our Ohio Utica shale mineral reserve. Because new wells have high initial production rates and follow a natural decline before settling into relatively stable long-term production, we expect royalty income in 2020 to decrease and be substantially lower than the 2019 level. This decrease is anticipated to occur primarily in the first half of the year, particularly in the first quarter as comparisons are made to historically high revenue levels in the first half of 2019 associated with increased production levels in the early stages of production from new wells. The reduction in royalty income is based on natural gas price expectations, fewer expected new wells and the natural production decline that occurs early in the life of a well. Decline rates can vary due to factors like well depth, well length, formation pressure and facility design. Also, as we mentioned in the earnings release, it is important to note these expectations for royalty income are dependent on a number of factors outside of our control. To summarize, overall, we anticipate 2020 consolidated net income to decrease compared with 2019 predominantly in the first half of the year. This is mainly because of the anticipated reduction in Minerals Management operating profit as well as the absence of $2.7 million pretax that was received in 2019 associated with the prior India venture and the absence of the previously mentioned $2.5 million tax benefit recognized this quarter. The 2020 full year effective income tax rate is expected to be between 10% and 12% based on the estimated mix of earnings and excluding discrete items. Before I open up the call for questions, let me quickly provide some balance sheet and cash flow information. We ended the year with consolidated cash on hand of $122.9 million and debt of $24.9 million. With regard to cash flow, we anticipate cash flow before financing activities in 2020 to decrease significantly from 2019 as a result of expected increased capital expenditures and payment of deferred compensation and other payroll liabilities. That concludes my prepared remarks. I will now open up the call for your questions.
