Earnings Call Speaker Segments
Operator
operatorGood evening, ladies and gentlemen. On behalf of Rain, we welcome all the participants to the Fourth Quarter 2020 Earnings Conference Call of Rain Industries Limited. The speakers on today's call are Mr. Jagan Reddy Nellore, Vice Chairman of Rain Industries Limited; Mr. Gerard Sweeney, President of Rain Carbon Inc.; and Mr. T. Srinivasa Rao, Chief Financial Officer of Rain Industries Limited. [Operator Instructions] Please note that this conference is being recorded. During the conference call, the management will be referencing and discussing a slide show presentation, which is available for viewing on our website at www.rain-industries.com in the Investor Relations section. It is recommended viewing this presentation while listening to the management's discussion. Before we begin, management would like to mention that some of the statements made in today's discussion may be forward-looking in nature that could be affected by certain risks and uncertainties. The company's actual results could differ materially from such forward-looking statements. Now if you could turn to Slide 3, I would request Mr. Jagan Reddy to provide an update on key developments within the Rain Group. Thank you, and over to you, sir.
N. Jagan Reddy
executiveThank you, operator. Good evening to everyone. I would imagine that like me, many of you are relieved that 2020 is over and looking forward to getting back to life as it was prior to the coronavirus pandemic. Despite 2020 being a year we all want to forget, it was the safest in the company's history with 13 of our sites completing the year without a recordable incident. In fact, across our organization, we have operated 252 days without a recordable incident. Other than a few weeks nationwide lockdown in India, no other production facilities globally were shut down due to COVID. We overcame significant damage from the strongest hurricane to hit the Louisiana area in the last 150 years and continued to operate our plant safely with only essential operators on site. We also freely executed our plan to cease operations at our Uithoorn facility and optimized production at our Duisburg site, essentially producing the majority of the same products at one site instead of 2. This improved efficiency is one of the reasons we were able to maintain EBITDA in the year that had reduced sales volume and many headwinds. Turning to Slide 4 of the presentation. EBITDA of INR 4.8 billion in the fourth quarter was down 7% from INR 5.17 billion during the previous quarter. This decrease reflects the seasonality of some of our products sold in Europe and North America from our Carbon and Advanced Materials segment, which are not in high demand in cold weather. Revenues for the fourth quarter was INR 26.4 billion compared with INR 25.66 billion in the third quarter. The sequential improvement in light of reduced earnings occurred primarily due to improved volumes and pricing and appreciation of euro against Indian rupees. This was the second consecutive quarter that we have seen an increase in revenues, giving us hope that global economy is returning to normalcy albeit slowly. On the Carbon side of our business, volumes were up about 4% and revenues increased about 7% from the third quarter. This was despite the lingering impact of damage caused by Hurricane Laura on our Lake Charles facility. Although we were able to restart both calcination kilns and electric generation plant, we lost about 1 month of energy income during the current quarter and were not able to produce CPC to capacity due to bottlenecks and other constraints caused by the widespread damage to the plant resulting under-absorption on costs. Our calcination business was also challenged by a continued worsening of global green petroleum coke supply. As we have seen throughout the pandemic, green petroleum coke prices continued to rise due to reduced refining of transportation fuels, which has negatively impacted refinery run rates and green petroleum coke production. On a positive note, bullish demand for aluminum and anodes required for smelting has resulted in higher CPC prices, helping to offset the green petroleum coke cost increases, providing an optimistic view for the coming quarters. During the fourth quarter, we began to prepare to suspend calcination activities at our Robinson, Illinois facility. A range of issues have impacted demand traditionally served from the facility, led by access to cost-effective raw materials. During the current year budgeting process, amid raw material shortages, it became clear that it would be more economical to suspend operations temporarily until the supply-demand situation improves, especially from a green petroleum coke perspective. We will service the Robinson plant sales volume from our Gulf Coast calciners. And in the coming months, we'll continue to evaluate the market for signs of improvement so we can resume calcination at Robinson. On the distillation side of our Carbon business, pitch volumes were lower largely due to the closure of an aluminum smelter and curtailments at an anode producer. On the margin side, we saw price pressure on traditional coal tar supplies as industries look for alternatives for raw materials typically sourced from oil refineries and add demand pressure. In terms of other carbon products, creosote volumes were down slightly due to its seasonality, while volumes of carbon black oil were up about 9% as we sold inventory that had built up from second quarter. Finally, crude naphthalene volumes grew by about 11%, thanks to the increased demand by the construction industry. Turning to Advanced Materials. Fourth quarter saw lower volumes, which resulted in 8% decrease in revenue compared with the third quarter. This was primarily due to a seasonal reduction in engineered product sales, in particular, our sealer-based products, which falls off in the winter months. Our PETRORES sales volume remains strong, which reflects the transition to electrical vehicles in many parts of the world, and sales of our CARBORES specialty binder increased by more than 9% during the quarter as demand from Asian countries rebounded as the impact of crude began to subside. Elsewhere, carbon resins sales were flat with third quarter and sales of our petrol resins increased during fourth quarter. Petrochemical intermediate volumes were up substantially, but pricing changed in line with the benzene quotations. Finally, sales of naphthalene derivatives during the fourth quarter were stronger due to increased demand for phthalic anhydride, [ CNS ] products and refined naphthalene by the construction industry. Regarding naphthalene derivatives. We closed the fourth quarter with the sale of our polymer business, which primarily consisted of our production facility in Candiac, Canada. This downstream business fell outside of our core businesses and had always been run as a stand-alone enterprise with few synergies other than utilizing naphtha oil produced at our distillation facilities. In our Cement business, there was an increase in volumes and revenue by approximately 11% and 2%, respectively, compared with third quarter. The sales volumes have improved across all regions where we operate. Segment EBITDA decreased by INR 252 million compared to third quarter, mainly due to lower realization. With good monsoons in South India, the rural economy should provide strong impetus to increased construction activity and thereby cement demand over the next several quarters. With this business update, I'll now turn over the call to Gerard Sweeney to take you through the industry and other business updates on Slide 5. Gerry?
Gerard Sweeney
executiveThank you, Jagan, and good evening, everyone. It's a pleasure to speak with you all again. Turning to Slide 5. Aluminum demand is now higher than pre-pandemic levels and with the LME prices more than $2,100 a tonne are the highest since late 2018. Also, increased demand is driving pricing as there appears to be a global shortage of scrap and primary aluminum. Amid growing demand and rising prices, an additional 4.7 million tonnes of smelting capacity, 3 million of which will be in China, is expected to come online during 2021 in the form of new plants and restarts of previously idled facilities. At the same time, the decision by the new U.S. administration to continue aluminum tariffs instituted by the outgoing administration and potentially reinstate others that had been lifted, should help to protect U.S. smelters from Chinese imports. These developments bode well for our carbon segment. Increased Chinese aluminum production should result in a decrease of CPC exports out of that country, creating more opportunity for us to serve the rest of the global market. Similarly, there should be less Chinese coal tar pitch exported to places like the Middle East and South Africa, which should be beneficial to us as well. In terms of aluminum pricing, we are now seeing deals in the market for low carbon aluminum. However, in Q4 of 2020, we began seeing companies pay a slight premium for low carbon aluminum. As smelters and anode producers look to capitalize on this emerging sustainability trend, we believe that our engineered anhydrous carbon pellets, or ACP, could be a differentiator in helping aluminum producers reduce their emissions and energy consumption, contributing to the marketability of their low carbon aluminum. Continuing on ACP, let us turn to Slide 6, our major projects. Construction has resumed at our ACP production facility in the United States and will commence in Q2 2021 in India after being halted due to the risk of COVID exposure amongst employees and contractors. Beyond its emissions and energy advantages, ACP will give us the unique ability to maximize our GPC feedstock as the rapid global transition to electric vehicles reduces demand for transportation fuels and the resulting availability of feedstock for our calciners. In a world where pet coke supplies are becoming increasingly tight, the ability to achieve enhanced green petroleum coke utilization rates when we calcine ACP by reducing the consumption loss during calcination could be a differentiator when it comes to production economics, raw material availability and sustainability. Construction on our new vertical-shaft calciner in India is largely completed, and we could begin production within weeks of receiving a satisfactory ruling on the importation of raw material feedstock for the facility. The ability to import the needed raw materials for the shaft calciner is critical because of the shortage of available domestic GPC. Across India, supplies have become even tighter as cokers are producing less pet coke during the pandemic and competition for domestic GPC versus higher cost imports has intensified. Once commissioned, each of these projects and their carbon-extending and emissions-reducing technologies will strengthen our position as a leading, sustainable global producer of essential carbon-based materials. Finally, an update on our new Hydrogenated Hydrocarbon Resins plant in Germany. After spending much of the second half of the year working with customers on product testing and validation, we reached our first sales milestone for our advanced water-white resins in the fourth quarter. The qualification process was understandably impacted by COVID since the pandemic has reduced customers' willingness to conduct testing and introduce new products while working with skeleton crews. Additionally, we continue to work to optimize operations of this plant. It is a highly sophisticated unit, introducing new technology and capabilities to the industry. Looking forward, we will continue to ramp up production and anticipate continually increasing sales volumes in 2021. Before I turn the call over to Srinivas, I would like to congratulate our employees for completing 2020 with a total recordable injury rate of less than 0.14, making it the third year in a row that we have established a new company best for annual safety performance. In any year, that would be a remarkable achievement. But the fact that we finished 2020 with so few recordable injuries is beyond remarkable when you consider that we achieved this while implementing radically new health and safety practices due to COVID as well as starting up our new advanced resins facility, dealing with a significant damage from a hurricane and completing one of the most complex maintenance turnarounds that we have ever attempted. With that, I'll now turn the call over to Srinivas, who will take you through the consolidated financial performance of Rain. Srinivas, over to you?
T. Rao
executiveThank you, Gerry, and good evening, everyone. It is a pleasure to speak with you today. In the fourth quarter of 2020, Rain achieved consolidated net revenue of INR 26.4 billion compared to INR 28.3 billion in the fourth quarter of 2019, a decrease of INR 1.9 billion or about 6.7% decrease. This resulted from a decrease in revenue of INR 2.34 billion or 12.3% decline from our Carbon business segment and INR 0.25 billion or 3.7% decrease from our Advanced Materials business, offset by an increase of INR 0.7 billion or 31.9% increase from our Cement business segment. Rain's consolidated adjusted EBITDA increased by INR 269 million compared to the prior year. This resulted from an increase in the Advanced Materials segment by INR 367 million and an increase in the Cement segment by INR 389 million, offset by a decrease in the Carbon segment by about INR 487 million. Now turning to the next slide on Carbon segment performance. Revenue from our Carbon segment was INR 16.71 billion for the quarter ended December 31, 2020, compared to INR 19.06 billion for the same period last year. During the year -- during the quarter, the sales volume decreased by 4.2%, primarily driven by lost CPC sales due to Hurricane Laura and reduced demand due to smelter closures. The average blended realization decreased by 8.5%, which was offset, to some extent, by appreciation of U.S. dollar and euro agonist Indian rupee by 3.6% and 11.5%, respectively. Overall, due to the aforesaid reasons, revenue from Carbon segment decreased by 12.3% during Q4 of CY 2020 as compared to Q4 of CY 2019. Adjusted EBITDA of the Carbon segment decreased by INR 487 million due to decline in volumes, majorly on account of Hurricane Laura. Turning to next slide on the performance of Advanced Materials. Revenue from our Advanced Materials segment was INR 6.57 billion for the quarter ended December 31, 2020, as compared to INR 6.82 billion for the same quarter in 2019. During the quarter, there was a 7.6% increase in volumes, driven by improved demand from Asian markets after recovery from COVID-19, improved demand from construction industries, coupled with higher throughput based on improved raw material availability. During fourth quarter of CY 2020, the average blended realization decreased by 10.5%, driven by changes in customer mix and a decline in oil-related prices, which was offset, to some extent, by appreciation of the euro agonist Indian rupee by 11.5%. Due to the aforesaid reasons, revenue from the Advanced Materials segment decreased by 3.7% during Q4 CY 2020 as compared to Q4 CY 2019. Adjusted EBITDA for the Advanced Materials segment increased by INR 367 million due to higher realization in engineered products and volumes in -- increase in volumes in naphthalene derivatives compared to Q4 of 2019, coupled with the appreciation of euro against Indian rupees. Moving on to the next slide, on Cement business. During the fourth quarter of CY 2020, Cement revenue increased by 31.9% compared to Q4 of CY 2019, due to an increase in realizations by 21.2%, along with an increase in volume by 8.8% as compared to last year. Cement EBITDA also increased by INR 389 million due to an increase in realizations, coupled with lower costs. Moving to the next slide, on debt. We ended the quarter with approximately USD 1,212 million of total debt, including approximately USD 77 million of working capital loans. Net debt was USD 932 million and based on LTM, EBITDA of $269 million. We ended the quarter with a net debt-to-EBITDA ratio of 3.5x. We are comfortable at this level as our average borrowing cost stood at 5%, and we expect it to remain stable since the floating rate portion of our long-term debt is tied to the EURIBOR, which is still negative. Referring to our previous discussions, cash outflow on capital expenditure and plant turnaround costs for the year ended 2020 totaled USD 146 million, which was more than expected because of -- because we resumed construction activities during the quarter on our ACP project and incurred expenditure related to Hurricane Laura. Regarding liquidity, we ended the quarter with $280 million of cash on hand and $130 million of undrawn revolver credit facility. The cash balance increased significantly due to proceeds from the sale of our polymers business. While this positions us very comfortably, we do not intend to maintain this position. Given the transaction closed on 31st of December, we are still in the process of evaluating all options available to us to deploy the proceeds efficiently. The primary goal is to reduce debt and reduce interest expense for the group. With that, I will now turn the call over to the operator for a Q&A session. Operator?
Operator
operator[Operator Instructions] The first question is from the line of Viraj Mehta from Equirus Securities.
Viraj Mehta
analystCongratulations for the numbers. So sir, if we were to normalize for the Hurricane Laura, what kind of volume growth we would have seen in the Carbon segment?
N. Jagan Reddy
executiveGerry?
T. Rao
executiveOn account of Hurricane Laura, we lost about 34,000 tonnes of CPC volumes.
Gerard Sweeney
executiveYes, that was the impact.
Viraj Mehta
analystOkay. And so the exit run rate that you mentioned about the CPC business, is it showing traction back to or higher than pre-COVID levels and September quarter as well?
T. Rao
executiveYes.
Viraj Mehta
analystOkay. Sir, second thing, we essentially sold the business to repay debt, is what we mentioned in our press release as well. But as we can see in the presentation today, our net debt has also gone up and our net cash has also gone up. I mean on a net debt level, it looks okay, but we are still not repaying debt. When does that start happening?
T. Rao
executiveAs you -- as I -- we just explained to you, the sale happened on December 31. So obviously, any reduction of the debt will not appear in the December 31 balance sheet. And second thing is you are able to see that there is an increase in the debt because the exchange rate -- we have about EUR 390 million of debt in Europe, and we are presenting the number in U.S. dollars and the FX rate between USD and euro -- euro has appreciated substantially against U.S. dollar. Last year, it was done at $1.12, and December 31, 2020, it is $1.23. So $437 million of euro debt has got increased to $479 million. About $42 million increase is there only because of exchange rates.
Viraj Mehta
analystOkay. And in terms of cash flows for this year, is it fair to assume that now that we don't have any major CapEx and normalization of margins is happening, all the cash flows will be utilized to reduce debt this year and onwards as well?
T. Rao
executiveWe can't say all cash, but we -- our idea is to reduce the debt in the due course. At an appropriate time, we will be using the cash to reduce the debt.
N. Jagan Reddy
executiveBut your understanding is correct that we want to reduce debt, and we will use all the surplus cash because we don't have major CapEx anymore.
Operator
operator[Operator Instructions] We take the next question from the line of Arvind Kothari from Niveshaay.
Arvind Kothari
analystSir, my question was on the up cycle that metals are experiencing. If you look at aluminum prices in China also, they are going up substantially. So in that kind of a scenario, I wanted to understand that we are suspending one of our facilities of Robinson's, and we had already suspended Gramercy calciner a year back maybe. So how are we preparing ourselves for the upside in the requirement of CPC given what the prices today are basically maybe reflecting higher demand going forward?
N. Jagan Reddy
executiveGerry?
Gerard Sweeney
executiveEssentially, you heard from our comments, we do have spare capacity from the calcination perspective. So we have 1 plant that we've taken down mainly due to both market demand and raw material availability. As the demand strengthens, while we have very strong pricing in aluminum right now, we need more demand, ultimately. So as that comes back, we will return to calcining at Robinson. And if we get a favorable ruling in the high courts in India, we can also start up our shaft calciner. So we're well positioned to feed continued demand growth from the aluminum sector going forward.
Arvind Kothari
analystSo on both, if you can give more color that how much time would it be there that -- once you try to start the Robinson facility, how much time does it take to restart the calciner? And also on the judgment of the Supreme Court, what is the current, you can say, position of the company in terms of when it expects or what is the judgment status right now? If you could elaborate.
N. Jagan Reddy
executiveSee, just to give you an idea -- okay. Please go ahead, Gerry.
Gerard Sweeney
executiveYes. As far as starting up a calciner, it's a matter of weeks. So it's not a very protracted process in order to bring a facility up. So that will not be a gating issue for us as far as meeting demand. As far as anticipated rulings of High Court in India, Jagan, why don't you go ahead and make comments about that?
N. Jagan Reddy
executiveYes. Actually, we have approached the government, as a matter of fact, seeking some permission for some job work. And we are actually hoping that we will get a response in the next 2 to 3 or 4 weeks actually. If we get a favorable response, that's fine. Otherwise, we'll actually approach the Honorable Supreme Court because this is one of the very few plants in the world that actually reduces pollution in India and not increases the pollution in India. So we think we can approach with the proper justification. And hopefully -- we are hoping that we should get some better -- favorable response probably, hopefully, in the next 2 months -- 2 to 3 months maybe. And once we have that, we can start the plant. And as Gerry mentioned, it may take about -- to start a rotary kiln calciner, say Robinson, it may take about 3 to 4 weeks. And to start a shaft calciner, it will take about 6 to 8 weeks.
Arvind Kothari
analystOkay. Great. And another question was on -- if you could give a bit of understanding on what the current dynamics are with -- related to metals, it looks like the metal companies are making greater margins. We being a converter, on the dynamics of both our distillation and calcining business, on the distillation side, what I understand is that the steel up cycle makes the availability of coal tar more easier for us, and that reduces our cost in that business. And basically, the aluminum up cycle gives us the opportunity to price our products higher because in that segment, at least, there are very few plants now which are working around the world, except China. So in that business, if that can increase our margins going forward, the converter margins? And on the calcining side, how are the dynamics, given both GPC and CPC are in a rising maybe environment? Dollar margin maybe going up, but percentage might remain the same. Is that correct?
Gerard Sweeney
executiveYes. The -- as far as the distillation margins, be it coal tar pitch or the related derivatives that we get off of -- the related products that we get off of the coal tar that we distill, look, dealing with -- I want to be very careful in a world where we have not seen full recovery from COVID yet in projecting too much. But your basic philosophy that you've expressed would be correct. So if we deal with the scenario of an improving commodity price for the sake of aluminum and oil price, those are favorable conditions for us from a margin perspective going forward. But we always have to balance supply and demand, the -- how the steel industry goes and demand for steel products affects our raw material supply as well. So we're always playing that spread between our cost for raw material and our finished sales price. But the momentum that's building up in a world where vaccines are being rolled out worldwide, and we are seeing industries return to -- from a pricing and from a volume demand perspective to pre-COVID-type conditions is absolutely bullish, and we are cautiously optimistic about what that can do for us in 2021.
Operator
operatorThe next question is from the line of [ H.R. Gala ] from Finvest Advisors.
Unknown Analyst
analystCongratulations to the team for really good operational results, although the selling prices and costs are not in our hands. My question is, looking from the medium-term perspective, how do you see next 4 to 5 years shaping for us? That is my first question, for 3 businesses. And what will be our capital investment plans matching with that objective?
Gerard Sweeney
executiveWell, we have spent -- the last several years, we have essentially made the investments to carry the company for the next 4 or 5 years. So your question is very timely. While we are still getting the investments over the last several years up and running, we really will be, we anticipate, ramping those investments up over the next 2 years and essentially getting them fully operational and producing at full rate, which will give us the capacity to carry the company over the next 4 to 5 years. We are also focused on doing this in the most environmentally friendly and sustainable format because that's really the marketplace that we're facing now as a company. We're not just extending -- as you heard Jagan say earlier, we're not just essentially adding capacities in new projects, but we're doing it with an extreme attention to environmental responsibility. And that will be our focus on the next 5 -- 4 to 5 years as a company, really taking advantage of the opportunity in front of us to produce clean, green, environmentally friendly products for the 21st century.
Unknown Analyst
analystHello?
N. Jagan Reddy
executiveYes, go ahead please?
Unknown Analyst
analystMy second question will be, what kind of capital expenditure we will be requiring every year to sustain the type of growth which we are expecting?
N. Jagan Reddy
executiveAbout -- see our normal CapEx is going to be about $65 million to $70 million. And our capital expenditure maybe -- basically maybe for this all -- we are talking about maybe $10 million, $15 million on an average because we are not planning to make any big investments at least for the next 4 -- 3 to 5 years.
Operator
operatorThe next question is from the line of Rohith Potti from Marshmallow Capital.
Rohith Potti
analystCongratulations on exceptional safety performance in such difficult times. Sir, my first question is on CTP business. I mean you've seen the volumes come down steadily. I was just curious to know how do you see that going forward and if you think the graphite electrode rebound that is happening right now can help us going forward.
N. Jagan Reddy
executiveYes. Actually, as a matter of fact, we expect strong demand for all our CDAM products going forward. And as a matter of fact, we are seeing that actually, be it our Advanced Materials or in the coal tar and derivatives. We are actually seeing very strong demand for all our products. So we only expect -- and the prices in China also having to be substantial, that will have a good bearing on rest of the world also. So we do expect strong demand going forward, at least in the near future, what we can see.
Rohith Potti
analystUnderstood, sir. That was helpful. Sir, next question is on the strategic nonrecurring expense of INR 55 crores that we have. I mean over the last few quarters, this particular line item is quite -- it's been actually quite recurring. So what is this about? And when can we see this particular line item not affecting us anymore?
T. Rao
executiveThis is basically the expenditure incurred for the new expansion project, while the cost incurred for creating an asset will be capitalized. But if any other expenses like operating staff recruited to run the plant or the timing of such expenses, those things are -- will not be capitalized, and it will be taken to the regular expenses, like, operating expenses. So we are adjusting them. Once these CapEx projects are completed, we can [ remove ]. And one more thing is the hurricane expenses, basically, because until such time we get the insurance, we cannot account for it. So we are actually basically expensing all the damage that caused cost due to the hurricane. And once we get the insurance, then basically we will actually add back to the overall revenue stream.
Operator
operatorThe next question is from the line of Pratiksha Daftari from Aequitas Investment Consultants.
Pratiksha Daftari
analystSir, my first question is on the CPC prices. I think for the last few quarters, we were seeing a declining trend and then a couple of quarters, it remained flat. We are now seeing an upward trend and the presentation says that the realizations have reached $385. I just wanted to understand like what kind of trajectory do we expect given the demand situation we have right now. And also, what kind of spreads do we see given that raw material prices are also increasing?
Gerard Sweeney
executiveYes. The -- on GPC, you're correct, the GPC price trend had been down. That was more reflective of demand. But as we've seen essentially less raw material available, that trend has reversed itself. And that's bolstered a -- that's bolstered essentially the price recovery that you've seen in the marketplace. That's going to continue as long as global refiners are in their reduced run rate due to COVID. That's mainly due to the global lack of demand for transportation fuels due to the interruption that's taken place. So most of that price increase that you're seeing is related to, again, the shortage of raw materials and rising prices for raw materials driving the finished product price. And the second part of your question I didn't get. If you can repeat it, please.
Pratiksha Daftari
analystI I was talking about the price -- increase in price that we are seeing in CPC and the spreads. What kind of spreads do we see between GPC and PPC going ahead? Do we see the spreads expanding?
Gerard Sweeney
executiveYes. The spread right now has basically been maintained. So that's indicative of our cost moving with our -- with the revenue side. And that's really projected throughout this year. With the 4.7 million tonnes of additional demand coming on globally, that could -- the expansion potential there for margin is there in the remainder of this year as that new capacity comes online, aluminum capacity, because the demand can be driven. But it will be the demand side that would allow us to expand our margin going forward. But I do see that as a better propensity than any squeeze on our margin through this year.
Pratiksha Daftari
analystOkay. And my next question is about the Robinson plant. What kind of volumes have been -- have you been doing from that plant in the last few quarters?
Gerard Sweeney
executiveYes. We've roughly been doing about -- over the last several years, about 150,000 tonnes a year from the Robinson plant. We have not been producing at full capacity. But that's roughly the volume that's been taken off.
Operator
operatorThe next question is from [ Vikram Sharma ] from Meraki Wealth Management.
Unknown Analyst
analystSir, we are facing many problems in ongoing CapEx. What total amount of cost increase in our ongoing CapEx due to delay in project? Also, sir, many things are on track now. Then what problems we are facing related to limited construction workforce availabilities?
N. Jagan Reddy
executiveSee, basically, I would say that we are actually experiencing project cost increases of about 10% to 15% because of the delays. Workforce, because of COVID, basically, say, in India, the workforce has come down pre-COVID, now the workforce is about 60% than what was needed. But we took a little extra time, but we did complete the plant. Now we are in the final stage of completion. Similarly, in HHCR, plant is more or less complete, and actually, we have started -- we actually -- the production has commenced. Now that we don't have any major investments, this should not impact us anymore.
Unknown Analyst
analystOkay. And sir, another in HHCR, there is a mention in our investor presentation operation team continuing to manage issues. So what is the issue exactly?
N. Jagan Reddy
executiveSee, basically, we have -- we are trying to -- see, normally, most of the HHCR projects use a particular raw material, but we're actually trying to use materials that we have. And so we are actually having a little more issues trying to use these new types of raw materials. And it's taking a little longer to stabilize. But the advantage of using this will be, we'll be able to reduce the raw material cost substantially. So hopefully, we are on the right trajectory. We are actually able to -- we are actually slowly getting there, and our products are actually being approved by a few of the customers. We are actually getting the record qualities. So -- but to stabilize a plant and especially HHCR plant is a very, very complicated plant, one of the most recently built plants and very few of [indiscernible] plants. So it's taken us a little extra time, but I am very sure that our team will be able to get there. So...
Operator
operatorThe next question is from the line of [ Gunjan Kabra ], who is an individual investor.
Unknown Attendee
attendeeSir, I wanted to ask, in the conference call of Alcoa, they guided that they project PCP price to increase in the first half of 2021. And also in the Koppers con call, they highlighted that the availability of coal tar next year will increase in the U.S., and they did not have to import from Europe and other countries thereby reducing their cost. Sir, where do we see the prices and the availability, cost of coal tar going forward for Rain industry? Sir, can we expect a better margin in this division going forward?
T. Rao
executiveGunjan, are you referring to availability of coal tar in North America? What is it you are referring?
Unknown Attendee
attendeeSir, in the conference call of Alcoa, they guided that they except the CPC price in the first half of 2021 to increase. And also Koppers said that the availability of coal tar in the U.S. has increased. So do we see the price and the availability or the cost of coal tar going forward for Rain? Like, what do you see on them? Can we expect a better margin from next 2, 3 quarters?
T. Rao
executiveBasically, Gunjan, both in the CPC business and CTP business, the pattern of changes between raw material and finished products will be the same. If continuously the raw material prices are increasing in line with the prices of raw materials, even the finished product prices will be increasing. Mr. Gerry also explained in the beginning that there is so much of aluminum production taking place in China and the rest of the world. There is more demand for the product, and the China exports are also declining. That is definitely result in increase in the prices of both CPC and CTP.
Gerard Sweeney
executiveYes, to add to what Srinivas just said, the -- earlier I was talking about the supply-demand economics on calcination. So you're asking more from the distillation side. We -- while the steel industry is essentially still depressed due to COVID and demand factors, we're comfortable with the opportunity that we have this year from the distillation side. We don't see the gating issue as much from demand because of the lesser amount of players from the distillation side that are in the coal tar pitch markets. So overall, we do see -- we are cautiously optimistic about the opportunity that 2021 and continually increasing demand will provide for the distillation business.

operatorThe next question is from the line of [ Saket Kapoor ] from Kapoor & Company.
Unknown Analyst
analystSir, firstly, if you could give the average utilization level, sir. How have they panned out over the last 6 months? And what was the average for the entire last year, for December '19, across the verticals?
N. Jagan Reddy
executiveYes. I would say that both 2019 and except -- barring India, where we had shut down the plants for about 4 to 5 weeks, I think both -- I think it was flat, actually, the capacity utilization in 2019 and 2020. But just to give you an idea, carbon sector is at about 80% capacity and Advanced Materials last year has had 65% capacity utilization. But you will see improvement in 2021 because Advanced Material, because we have only 1 plant now and basically the demand has actually picked up quite a bit, so you will see a much higher capacity utilization closer to almost 90% plus. In Carbon also, whatever -- except plants that are not operating due to various reasons, be it Robinson and the India SEZ plant, we expect the average capacity to be above 90% this year.
Unknown Analyst
analystBut with the sale of the unit, sir, how much will -- there will be a decline in the revenue. The existing one will be ramping up from 60 to 90. So what will be the decline in the revenue in absolute terms, sir?
N. Jagan Reddy
executiveRevenue, that was contributing about $80 million of revenue.
Unknown Analyst
analystRight, sir. Sir, we also see this depreciation part also being higher. So what is our current capital work in progress, sir? And what are the new projects that are planned to be capitalized in the near future?
T. Rao
executiveActually, in 2020, the depreciation is higher for 2 reasons. Reason one is we have capitalized HHCR plant in June 2020 quarter. And so we started providing depreciation on that. Though the trial productions are going on and the revenues are not generated, we are depreciating because the plant is ready and construction is completed. Apart from that, we also have implemented the new lease standard where assets taken on operational lease also is expected to be capitalized. That has resulted in about -- on a quarter, about 3 million -- $3 million to $3.5 million of additional depreciation is getting provided. But that is only a reclassification of operating expenses, lease rentals into partly as depreciation and partly as interest. And the 3 projects under construction are, like, the ACP projects in India and U.S. Once they are completed, we will be capitalizing. And the vertical-shaft plant also will be -- what we are constructing in SEZ in Visakhapatnam, India, that also gets capitalized once the construction is completed mid of 2021.

operatorThe next question is from the line of Tirath Muchhala from Elusividya Advisory.
Tirath Muchhala
analystI wanted to know that about a year ago when we broke out the Advanced Materials segment, there was a focused thrust on catering to battery technologies or energy storage technologies, and there were a few senior recruitments that we had done. So my question is that are you seeing increased demand from those industries, be it lithium-ion or any other kind of energy storage industry?
N. Jagan Reddy
executiveQuite a bit. As a matter of fact, we are actually seeing quite a bit of demand from the battery industry to an extent where we are not able to service that much quantity. And we are actually trying to figure out can we do a small CapEx or something like that so that we can actually get there to be able to meet this demand. Yes, basically, whatever we said last year of the increased demand, we are seeing that, and it is actually growing quite a bit. So and our team actually is doing a good job of actually trying to make the product required...
Tirath Muchhala
analystSo any kind of expansion in that segment, would it be R&D related? Or would we need to acquire some expertise? Or how would it work? Or is it not a material contributor to our company even going forward?
N. Jagan Reddy
executiveNo, no, actually, it will be our own proprietary technology. We don't need to acquire from outside. It will be based on our own R&D. And it is actually a product that we do make, but the demand is for much larger quantities.
Operator
operatorThe next question is from the line of [ Bhavesh Patel ] from Patel Investments.
Unknown Analyst
analystFirst of all, congratulations on relatively good numbers with a COVID backdrop and also thinking strategic for years ahead. My question is, when do we expect our Germany plant, which produces the water-white resins, to get close to 100% utilization? And I know this is forward-looking, but just to get an idea because we have signed up and seen some success with initial customers and also important because this is our highest-margin product comparatively.
N. Jagan Reddy
executiveSee, basically, we hope to be able to -- the plant should reach the capability to produce at a higher capacity probably in the next 2 to 3 quarters. But we also have to -- our product has to be tested by various customers and it has to be accepted. So the trajectory may be a little bit higher. So this year, for 2021, we are targeting a capacity utilization of about 70% and probably increased ramp-up in the next 1 year or so thereafter.
Unknown Analyst
analystFantastic, fantastic, that sounds pretty good. And the next question is, in terms of next 4 to 5 years and, again, you have listed out your priority to reduce debt. Do we consider this to -- for us to be able to achieve close to, let's say, even 15% to 20% of the current debt that we have on the books that sets up for a very, very strong future ahead with much lesser drag on -- from the debt that we have, which is close to $1 billion?
N. Jagan Reddy
executiveSee, actually, if you look at our debt, we have $1 billion, but our net debt now, I think, in December '20, it's only about $800 million plus. So our target is to reduce in the next few years because, as we said, we don't have any major CapEx. Like Gerry was mentioning earlier, in the last several years, almost -- I would say, almost 7, 8 years, we were continuously investing on CapEx, and we want to bring down that. And so we should have improved cash flow, both from our normal cash flow as well as these new projects that are actually going to -- basically also should throw up some cash. So based on that, we do expect to reduce our debt. And I cannot comment on how much exactly we can say, but we do expect that it should come down. Our target debt-to-EBITDA ratio should be to be well below 2.5, is our target to be as soon as possible. And also, we want to bring down our average interest rate to about to 4%, which we are hopeful that we can do it in the next 1.5 years.
Operator
operatorThe next question is from the line of [ Akhilesh Kumar ], who is an individual investor.
Unknown Attendee
attendeeJust in the call, I have heard Jagan and Srini mentioning that our vertical-shaft plant is complete and we are just waiting for the government permission for importing the GPC. So if I take on that, your estimate of, say, 1, 2 months to get the government permission and then an additional 1, 2 months for plant to restart, effectively, we are hoping for not before Q3 to a start, right?
N. Jagan Reddy
executiveQ3 may be a possibility.
Unknown Attendee
attendeeOkay. And that also only if we don't end up going to Supreme Court, right?
N. Jagan Reddy
executiveSee, this time, we have asked for permission from the government. And without getting the government permission, we should not be questioning -- basically going and saying that we'll approach Supreme Court. We are hoping that government will take a favorable decision soon.
Unknown Attendee
attendeeYes. And I have one more thing, just wanted to check on it. Like, our Indian smelters, are they not still facing any issue, constant, because of these import coal tars of CPC? Or like, say, they are not approaching government or Supreme Court?
N. Jagan Reddy
executiveNo. They are actually -- we actually -- our thought process, in any case -- next time we want to request audience members also join [indiscernible] Honorable Supreme Court because it's impacting all of us. Especially now with -- you have read from the press statements that Nalco is talking about increasing capacity, Vedanta is expanding. So if everyone needs material and India is talking about Atmanirbhar Bharat, if you want to maintain all of this, India's production has to increase. And one good thing, as we said earlier, this process actually reduces pollution in India and doesn't increase. With all these benefits, we see the government actually taking a favorable decision soon.
Operator
operatorWe'll take that as the last question. I would now like to hand the conference over to Mr. Jagan Reddy for closing comments.
N. Jagan Reddy
executiveThank you. Two months into the first quarter, there is ample reason to be cautiously optimistic about 2021. With the recent introduction of COVID vaccines around the world and a steady decline in the number of positive cases, demand for many of our products is nearing a return to pre-pandemic levels. The surge in aluminum demand and aluminum prices is also very positive and a sign that we could be entering in a commodity super cycle with a multiyear growth trajectory. In the months ahead, top priorities will be to further ramp up sales and production of our advanced resins and to commission the shaft calciners and ACP production facilities. Beyond that, we know that we must continue to aggressively manage costs, including a reduction in CapEx spending as our major projects are completed. At the same time, generating new and reliable cash flows will allow us to reduce the company's debt profile. Finally, we must continue our metamorphosis into a 21st century company that transforms industrial byproducts into essential materials for lighter, cleaner and faster products and applications that have a dual benefit of creating new market opportunities for our company and driving long-term value. In a society where sustainability is quickly becoming a license to do business, our ability to maximize the productivity of carbon by upcycling these byproducts makes Rain an indispensable player in an increasingly sustainable society. Thank you all for joining us today. Best wishes in the months ahead. Stay healthy and safe. And we'll speak with you again in the next quarter. Thank you very much.
