Thanks, Louann. Before I get into discussing the outlook on our business, I'd like to take some time to provide a high-level summary of all that's been done as part of transforming Koppers and strengthening our competitive edge in the marketplace over the past two years. Number one, as I alluded to in my opening, everything for us starts with safety for our people, the environment, and our communities. We tweaked our mission statement over the past year to reflect that. It now reads creating safe and environmentally responsible solutions that solve our customers' most important challenges and result in superior performance for shareholders. While safety performance tends to get defined as a metric, I prefer to think of it from a human perspective because I think it gives a better sense of what we've actually achieved while also putting into focus how far we still have to go to achieve Zero Harm. Over the past two years, we have reduced the number of our people that are injured on the job and had to seek medical attention by close to one-fourth and in 2016 had our best safety year ever. Imagine that. That equates to around 20 less people being injured on the job over the course of a year. Flip it around, however, and it shows that we still have 62 people that were injured during 2016, which is 62 too many. Zero will remain the goal and the focus, and I'm confident that, over time, we will get there. We plan to share our progress on the environmental and community front in our upcoming sustainability report for 2016 that should be issued sometime within the next couple of months. Number two, we believe Koppers is now the leading global producer of wood preservatives and number one in most major wood preservative markets across the globe. Through our vision adopted in late 2015 of striving to be recognized as the standard-bearer for safely delivering customer focused solutions primarily through the development and application of technologies to enhance wood, we've been able to realign our portfolio substantially. The result is that wood-related revenues now make up 60% of our topline at the end of 2016 compared to 47% at the end of 2014, and our consolidated adjusted EBITDA has gone from $116 million to $174 million in two short years. Number three, we've drastically improved the health of our balance sheet over the past two years. While I'm disappointed that we fell short of our $200 million debt reduction target, we did make a substantial dent in our debt by repaying $178 million over that time frame. As Louann mentioned, we have replaced higher cost secured bonds with lower cost unsecured debt while also eliminating the required amortization of our term loan. Those moves have improved our liquidity dramatically while also substantially reducing any worries about the possibility of tripping debt covenants if one unfavorable event would surprise us. In the process, pro forma net leverage has been reduced from 5.2 times as of 12-31-2014 to 3.7 times as of 12-31-2016. Number four, through our strategic decision to deemphasize CM&C, we've now refocused our efforts on serving end markets that seem to be inherently more stable through an economic cycle. With the primary driver of both RUPS and PC being repair and maintenance or replacement, our business is somewhat less subjected to large swings up or down based upon macroeconomic factors. Our RUPS and PC businesses collectively made up 69% of 2016 revenues compared to only 46% in 2017. Number five, we've leveraged our historically strong relationships in our RUPS and PC segments to extend sales commitments out several years, thus solidifying a critical baseload of business. In fact, as I mentioned earlier on the call, we have just come to terms on an extension with another major U.S. Class 1 railroad and now have a significant contractual volume with the four largest U.S. Class 1 railroads that take us into 2021. On the PC side of the business, we have commitments for micronized copper products in place for approximately 35% to 40% of our expected 2018 U.S. demand and close to 20% of our expected 2019 U.S. demand. Number six, as of year-end 2016, we've now ceased coal tar distillation as sold seven out of 11 CM&C global operating facilities, drastically cutting our fixed cost structure. Those moves, in combination with the recently negotiated long-term raw material supply agreements, enabled us to increase our adjusted EBITDA in CM&C from $9 million in 2015 to $23 million in 2016 in an environment that saw average crude oil prices 11% lower, our average global end market pricing 5% lower and our sales volumes 23% lower than prior year. Number seven, we significantly reduced our exposure in China by ceasing distillation at our majority held joint venture, KCCC, in February 2016 and closing on the sale of our minority held joint venture, TKK, in November 2016. During the year, we were also able to confirm Nippon Steel Sumikin's commitment to comply with our revised supply contract with their Chinese subsidiary that assures us a certain level of profitability even if they are not taking contracted volumes. As a result, sales from our CM&C China operations have declined from $199 million 2014 to $80 million in 2016 while adjusted EBITDA for that region has improved by $11 million. Over the past two years, we have divested six operating units or facilities that either were not core to our future business focus of wood preservation or were underperforming without a clear path forward for growth for improvement. In January 2015, we sold our U.S. utility business. In July 2015, we sold our concrete tie joint venture. In July of 2016, we sold our two UK coal tar distillation facilities. In October 2016, we sold our small residential wood treating business based in Houston, Texas. And finally, in November, we sold our minority interest in our TKK joint venture in China. What we gave up through those asset sales was less than $100 million of consolidated sales that were running at a collective operating loss. What we received from those asset sales were net cash proceeds of $11.1 million in 2015 and 2016, a $5.2 million repayment of principal and accrued interest on an overdue loan thus far in 2017 with $4.8 million to be paid in the next 45 days, and we reduced future environmental overhang by $8 million to $20 million. Finally, number nine, over the past two years, we've delivered impressive returns for our shareholders, recouping almost all of the value lost during the oil and aluminum drop in 2014 and 2015 and finished well ahead of most major market indices in that time frame. Our two-year total shareholder return equates to 55% while, in 2016 alone, we were up by 121%. Now, as impressive as that list is, it's far from exhaustive. There were actually many other significant accomplishments that occurred behind the scenes that have helped build a strong infrastructure and supportive culture to allow us to reach these more visible accomplishments. In the constant drive to push our people to do better, it's easy sometimes to lose appreciation for the enormity of their accomplishments. It almost becomes expected. I can't let that happen here at Koppers, so with that in mind, I want extend my sincerest gratitude for all our 1,800 plus employees from Ashcroft, British Columbia to Auckland, New Zealand and everywhere in between. None of what I just reviewed occurs without their faith in our vision, their ingenuity to think of new ways to solve old problems, and their commitment to make it all happen. Now let me speak for a few minutes about how I see the outlook for each of our business segments in 2017. Beginning with performance chemicals, this business continues to benefit from a building materials market that has consistently performed at an above average pace for most of 2016. From everything I hear and read, that pace is expected to continue into 2017. The National Association of Realtors estimates that existing home sales will increase by 2% in 2017, which has historically resulted in greater spending in the repair and remodeling sector. According to the Leading Indicator Remodeling Activity, or LIRA, which is the Joint Center for Housing Studies at Harvard University, strong gains in home renovation and repair spending are expected to continue into mid-2017 before moderating somewhat later in the year. The National Association of Homebuilders also appears to validate those projections due to aging in-place homes and rising home equity. In addition, Zillow estimates that there are 12% more fixer-upper homes on the market now than five years ago, and even more among high-priced homes in attractive real estate markets. The level of confidence in the home purchase renovation and repair market is supported by information provided by the Conference Board which reported consumer confidence of 107.1 in November. That represents the highest level seen since July 2007 and an increase from 100.8 in October. As a result of those bullish indicators, we are expecting to generate 2017 adjusted EBITDA of approximately $85 million for PC, which is a $5 million increase from prior year, as reflected on Page 8 of our slide presentation. Now, a few caveats that I would like to give to these projections is where copper prices and interest rates go in 2017. We are substantially protected through hedges we have in place for 2017 for copper, but a sudden and significant rise in pricing could be difficult to recoup in the near term for the portion of our business that's not hedged. As far as interest rates, it has been many years since we have been in a rising interest rate environment, and much has changed in this industry since that time. We will certainly be keeping a close eye on how rate increases might affect the positive repair and remodeling trends that we have been experiencing for some time now, and just want to alert our analysts and shareholders of that fact as well. Moving now to the outlook for our railroad and utility products and services business, the demand trends from the Class 1 and the commercial sector are lower than the past couple of years and the sluggishness that we saw in the back half of 2016 is expected to continue throughout 2017. According to the Association of American Railroads, overall levels of railroad investment are forecast to be $22 billion, a decline from $25 billion in 2016 and $29 billion in 2015. The decline is driven primarily by a reduction in coal transportation due to low natural gas prices and environmental concerns regarding the burning of coal. This has had a negative impact on Class 1 revenues and subsequently made it harder for the railroads to maintain the CapEx programs at the same levels as they have in previous years. Due to the conditions I just described, the typical spring kickoff for cross tie insertions will likely roll out slower than the past few years despite very mild winter weather. Longer-term, we still believe strongly in the need for sustained investment in infrastructure to keep the railways safe and running at optimal performance levels. As reflected on Slide 9, we are providing 2017 adjusted EBITDA guidance for our RUPS segment of approximately $64 million, which is an $8 million decrease from prior year. Now, that $8 million decrease more or less represents the annualization of what we experienced in our cross-tie business over the second half of 2016. While there's a lot of speculation about the new administration's commitment to infrastructure spending, any benefit to increased rail traffic as a result of increased spending would still not be expected to trickle down to our industry until 2018 as we typically lag the rail cycle. Now let's review the outlook regarding our CM&C business. On Slide 10, our anticipated 2017 adjusted EBITDA guidance for CM&C is approximately $32 million, which represents a $9 million improvement over prior year. I've already talked at length about the many changes we've made in this segment to both improve and stabilize profitability, so I won't repeat myself again on those matters. But I will say that there are still opportunities for taking more costs out of CM&C and we will be relentlessly focused on that in 2017 and 2018. A point that I'd like to make about this segment that's not obvious from the slide is that the forecasted downturn in railroad cross tie volumes and its follow-on effect on creosote volumes is essentially muting most of the benefit we are forecasting for $50 average crude oil prices. In general, we have reduced the impact from oil on this segment significantly with the changes we believe -- on the segment significantly, and with the changes, we believe that our sensitivity now runs closer to $4 million or less of EBITDA impact for every $10 change in crude oil prices. Despite the many moving parts, we are making tangible progress towards our goal of delivering 9% to 15% adjusted EBITDA over the cycle. I will tell you, as I sit here today, I actually have the highest level of confidence in this segment being able to meet and possibly beat our 2017 projections. A clear example of the improvements made by our CM&C segment is it delivered 5.3% adjusted EBITDA margins in 2016, which is an increase of 380 basis points from prior year. 2017 adjusted EBITDA margin is expected to be around 7.5% with one more big jump to make in 2018 when the new naphthalene unit is online at Stickney. Now, while CM&C volumes have stabilized and performance chemicals demand is expected to stay strong, softness in our RUPS business will likely keep consolidated sales for 2017 at approximately $1.4 billion, as reflected on Slide 11, while our focus will continue to be on maximizing our profitability. Turning to Slide 12, our guidance for 2017 consolidated EBITDA on an adjusted basis is targeted to be $180 million compared with $174 million in 2016. Once again, I will stress that while I believe there is the potential for some upside with CM&C, we need to exercise caution related to our RUPS and PC businesses. As always, we will provide updates each quarter and let you know if any assumptions or drivers may change. Our adjusted EPS guidance is projected to be between $2.75 and $2.85 compared with $2.60 in 2016. The increase in adjusted EPS is due to a combination of improved operating profit and lower interest expense, partially offset at the lower end of the EPS range by a potentially higher effective tax rate. Capital expenditures in 2017 are expected to be approximately $70 million to $75 million, consistent with our plans for the completion of a new naphthalene unit at our Stickney, Illinois facility, while also investing in capacity additions from our PC business. Overall, I'm pleased to say that our performance to date has shown significant improvement and we remain committed to continually assessing our operations for improvement opportunities. The extensive and ongoing efforts we've undertaken to reduce our fixed cost structure over the past two years have resulted in significantly lower earnings volatility. Also, in the past two years, we've aggressively reduce debt and strengthened our balance sheet while our recent bond financing transaction provides us with greater flexibility to pursue opportunities to invest in our business. These actions are part of advancing our Company's strategy to be the global leader in wood preservation-based technologies, expanding our profitability, and driving shareholder value. I would now like to open it up for questions.
