Good morning, everyone, and welcome to our 2018 earnings conference call. I am Christina Kmetko, and I am 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 second quarter 2018 results and filed our 10-Q. Copies of our earnings release and Q are available on our website at nacco.com. For anyone who is not able to listen to today's entire call, an archive 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-Q. Now that I have the formalities done, let's talk about the quarter. Yesterday, we reported consolidated income from continuing operations of $6.4 million, or $0.92 per share for the second quarter of 2018. This compares to consolidated income from continuing operations of $7.2 million, or $1.06 per share, for last year's second quarter. Our year-to-date effective income tax rate was 12%, within the range we provided previously. As the majority of our consolidated results are derived from our North American Coal business, I'll explain the results by explaining what happened to that business. At North American Coal, coal deliveries increased 8.8 million tons in the second quarter 2018 from 8.2 million tons last year. Limestone deliveries at our North American Coal Mining division also increased 8.4 million yards from 7.9 million yards in the second quarter of 2017. The increased deliveries of both coal and limestone occurred predominately at the unconsolidated operations. Pretax income decreased to $9.4 million from $10.3 million last year at North American Coal. This decrease is mainly because of the absence of $2.6 million from gains on sales of assets in the second quarter of 2017. Excluding the effect of the gains, pretax income at North American Coal increased primarily as a result of an increase in earnings at the unconsolidated operations. These improvements were partly offset by a decrease in income at Mississippi Lignite Mining Company, resulting from an increase in the cost per ton of coal delivered, which was driven principally by higher repairs and maintenance costs during the quarter. In addition, North American Coal realized an increase in operating expenses due to higher professional fees. At NACCO and other pretax income from continuing operations is comparable between periods. Looking forward in the second half of 2018, we expect our consolidated pretax income to increase substantially compared with the second half of '17 even though that the second half of 2017 included $2.1 million of gains on sales of assets that are not expected to be repeated this year. The combination of a modestly stronger than expected second quarter and the anticipated improvement in the second half of 2018 are expected to result in an overall moderate increase in our 2018 full year pretax income. We continue to expect the consolidated effective income tax rate in the range of 9% to 12% for the full year. However, because of the anticipated increase in the 2018 effective income tax rate compared with 2017 2.2%, we expect consolidated income from continuing operations in the second half of 2018 be comparable to the prior year period, and be down modestly for the full year. We expect improvement in the second half of this year as a result of improved income at our consolidated operations, lower operating expenses mainly related to lower employee related costs, and reduced interest expense on substantially lower borrowings outstanding. We expect these improvements to be partially offset by a decrease in loyalty and other income during the second half of the year. At our consolidated operations, Mississippi Lignite Mining Company's pretax income in the second half of 2018 is expected to increase substantially over the second half of last year and the first half of this year, primarily as a result of a reduction in the cost per ton of coal delivered because customer demand in the second half 2018 is expected to return to higher levels. Much of this improved second half income is anticipated in the third quarter and we expect this improvement to offset the lower income in the first half of 2018, resulting in full year 2018 income at Mississippi Lignite Mining Company to be comparable to 2017. Customer demand did not improve, as expected it couldn't favorably affect North American Coal's 2018 earnings significantly. Earnings at our unconsolidated operations in the second half of 2018 are expected to be comparable to last year. We are pleased to note that during the second quarter of 2018, North American Mining signed two new contracts with limestone customers. Operations under one contract are expected to commence in the fourth quarter of 2018, while operations under the second contract are expected to commence in early 2019. Before I wrap up, let me provide you with some cash flow and balance sheet information. We expect cash flow before financing activities to decrease substantially in the second half of the year compared with the second half of 2017 resulting in an overall decrease in cash flow before financing activities for the full year. This decrease is due in part to an increase in planned capital expenditures at North American Coal. We ended the second quarter with consolidated cash on hand of $80 million, and debt of $28 million. This compares to consolidated cash on hand of $101.6 million and debt of $58.1 million last year or at the end of 2017. The decrease in cash was tied to the reduction in debt. Also in February 2018, our Board of Directors authorized a stock buyback program to purchase up to $25 million of our outstanding Class A common stock. We did not repurchase any shares during the first quarter of the program but we did repurchase approximately 1,700 shares, during the second quarter for an aggregate purchase price of approximately $100,000. This program runs through December 31, 2019. That concludes my prepared remarks. I will now open up the call for your questions.
