Thank you. Good morning, everyone, and welcome to our 2017 fourth quarter earnings call. I am Christina Kmetko, and I am responsible for Investor Relations at NACCO Industries. I'll be -- 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 America Coal; and Elizabeth Loveman, NACCO's Vice President and Controller. Yesterday, we published our fourth quarter 2017 results and filed our 10-K. Copies of our earnings release and 10-K are available on our website at nacco.com. For anyone, who is not able to listen to today's entire call, an archived version of this webcast will be on our website later this afternoon and available for approximately 12 months.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 were set forth in our earnings release and in our 10-K. Now that I have the formalities done, let's talk about the quarter. As we discussed on our third quarter call, we successfully completed the tax-free spinoff of our housewares-related businesses of Hamilton Beach brands and Kitchen Collection on September 29, 2017. As a result of the spin, the 2017 and 2016 financial information in our earnings release and 10-K reflect the housewares business' operating results as discontinued operations. Today's discussion will exclude the housewares business and focus only on income from continuing operations, as this reflects our post-spin ongoing business. In addition, as I explained last quarter, I will discuss segment results to pretax income and then cover taxes and net income at the consolidated level. Now let me discuss our results for the fourth quarter. Yesterday, we reported consolidated income from continuing operations of $9.7 million or $1.40 per diluted share, which include the provisional tax benefit of $4.5 million or $0.65 per share related to U.S. tax reform. This compares with a consolidated loss from continuing operations of $4.6 million or a loss of $0.68 per share last year. At our North American Coal business, pretax income increased in the fourth quarter of 2017 to $8.2 million from $1.1 million last year. The improvement was primarily due to higher royalty and other income, an increase in the earnings at our unconsolidated mining operation and a reduction in lease expense as well as the non-recurrence of a $3.3 million charge in 2016 related to the resolution of the Centennial legal matter. These improvements were partly offset by an increase in operating expenses and substantially lower results in Mississippi Lignite Mining Company. Mississippi Lignite's results declined because fewer tons were delivered and our cost per ton delivered increased. Our NACCO and other segment reported a pretax loss from continuing operation of $2.4 million in the fourth quarter of 2017 compared with a loss of $1.4 million in the prior year fourth quarter. The loss increased primarily due to revisions of estimated long-term Bellaire mine reclamation expenses, partially offset by lower employee-related costs. On a consolidated basis, we reported pretax income from continuing operations for the quarter of $5.8 million and an income tax benefit from our continuing operations of $3.9 million. For the full year, we reported consolidated income before income tax from continuing operations of $29.1 million and an income tax provision on continuing operations of $600,000. As a result of the accounting, we had to follow to allocate our full year income tax expense between continuing and discontinuing operations, and the benefit we reported in the fourth quarter as a result of U.S. tax reform, our 2017 effective income tax rate is not meaningful or indicative of our future expectations. Looking forward, we expect the consolidated effective income tax rate in the range of 9% to 12%. On a consolidated basis, we expect our 2018 pretax income decreased compared with last year, as 2017 results included $4.6 million of gains on sales of assets and a $2.8 million favorable adjustment to Centennial mine reclamation liability as well as higher royalty revenue. Excluding these favorable 2017 items, we expect 2018 pretax income to increase compared with 2017, primarily as a result of lower operating expenses, improved income at both the consolidated and unconsolidated mining operations and reduced interest expense. These improvements are expected to be partially offset by an anticipated substantial decrease in royalty and other income. At our consolidated mining operations, Mississippi Lignite Mining Company's 2018 full-year results are expected to improve over last year because customer demand is expected to return to historical levels as a result of an anticipated reduction in outage days at our customer's power plant. While the total number of outage of plant -- power plant outage days for the full year is expected to decline, a majority of these outage days are expected to occur in the second half of the year. As a result, Mississippi Lignite Mining Company's pretax income in the first half of '18 is expected to be comparable to the first half of 2017, while pretax income in the second half of the year is expected to increase over the second half of 2017. We expect that income from our unconsolidated mining operations will be modestly higher in 2018, due in part to higher fees at Liberty Fuels and increases at our North American Mining's unconsolidated limerock mining operations. Our Bisti Fuels mining operation is expecting a lower start to the year, while the owners of the power plant it serves installed additional environmental controls at the plant. But overall, Bisti's full year 2018 pretax income is expected to be comparable to last year. One additional item I'd like to discuss before I wrap-up the operating results. As you may have already seen on February 8, 2018, our customer Mississippi Power instructed our Liberty Fuels mines to permanently cease all mining and delivery of lignite and to commence mine reclamation. The terms of our contract with Mississippi Power specify that Mississippi Power is responsible for all mine closure costs and Liberty Fuels is specified as the contracted to complete final mine closure. We will receive compensation for these services. Overall, the customer's decision to close the mine does not negatively impact our 2018 earnings outlook for Liberty Fuels, but it does unfavorably affect North American Coal's long-term earnings potential from this mine. Lastly, regarding our cash and our balance sheet. We expect cash flow before financing activities to decrease substantially in 2018, due in part to an increase in capital expenditures at North American Coal. Overall, we ended the fourth quarter with consolidated cash on hand of $101.6 million, debt of $58.1 million and net cash of $43.5 million. 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. This program will expire on December 31, 2019. Our previously authorized share repurchase program expired at the end of 2017. That concludes my prepared remarks. I will now open up the call for your questions.
