Garry Rogerson - CEO
Welcome, everyone, and thank you for joining us this morning. I would like to begin with a few comments on the fourth quarter and then discuss our progress on our recently announced strategic plan.
Fourth quarter results met our expectations. While sales of our large scale inverters continued to climb, weak capital spending affected our Thin Films end markets to varying degrees. Total revenues declined 12.5% sequentially to $112.5 million, and we achieved breakeven at $0.01 per share on a non-GAAP basis. We ended the quarter with $143.2 million in cash, having generated approximately $6 million during the quarter, excluding stock repurchases.
At our Analyst Day in November we presented our strategic plan, including Company-wide and business unit goals and long-term operating targets in order to maximize shareholder value. We began executing on this plan immediately, and I am pleased to report several accomplishments that should allow each business unit to remain more stable in difficult times while enhancing profitability as revenue grows.
Turn to slide 5. Our Company-wide effort to reduce costs and improve margins remains front and center. As you know, in the third quarter, we decreased our annual costs by approximately $6 million. Since then, we have completed several more steps in our planned restructuring. We consolidated our presence in Fort Collins, exiting two buildings primarily associated with Thin Films. Given our large footprint, we will continue to look for opportunities to combine facilities. Similar to our actions in the third quarter in Thin Films, we streamlined our Solar Energy workforce in December, which will save us approximately $5.5 million annually. We also began transitioning the sub-assembly manufacturing for our Solar Energy products to our world-class production facilities in Shenzhen, China. We are making good progress in clearing the production stage and preparing the operations area to receive sub-assemblies. Though this process will take some time, and until it is fully operational, it will set the stage for us to begin low cost sourcing in the region, which will likely be the most significant area of cost savings.
Finally, we redesigned our executive compensation plan this quarter, more closely aligning it with the interests of our shareholders and reinforcing the pay-for-performance structure. By integrating the new plan into our 2012 to '14 strategic plan, we have reiterated the importance of long-term incentives in achieving our objectives and attracting, motivating, and retaining key talent. Grants will now be provided over multiple years, vesting only when certain Company and business unit financial goals are achieved. This over an extended period of time should reduce the impact of stock remuneration, reduce dilution, and significantly impact the P&L.
Overall, we delivered on our stated restructuring goals for the fourth quarter. The actions we have taken in the last two quarters have resulted in a total of approximately $12 million in annual savings, above our initial targets. There is still a long way to go. We should continue to expand on our near-term savings in the next quarter or two, but more substantial savings are expected to occur over time, as we rely more on the Shenzhen facility and less on local suppliers. Once we complete the two phases of the restructuring efforts, we expect to surpass our originally stated goal of $16 million to $20 million. While cost reductions are never easy, I am proud of the cultural shift that we are stimulating at the Company to one that is more passionate about costs, whether at the gross margin or operating level. We are focused on putting measures in place to make sure these costs do not come back.
Another important step was the announcement of our $75 million share repurchase plan at Analyst Day. In the last quarter, we bought back approximately 1.7 million shares of stock. We plan to buy back stock opportunistically throughout the year. In combination with our redesigned incentive plan, we expect this to put us squarely on the path to reducing our dilution from the current rate of 4% to our targeted 1.5% in the next few years.
Turn to slide 6. As we have become more cost conscious, we also need to become more customer focused if we are to successfully expand our revenue and customer base. We begin this process during the quarter by establishing a worldwide presence closer to our customers. First, we built out our engineering team in San Jose, California, where we can more quickly and effectively serve the needs of our Silicon Valley customers. We plan to add a Korean R&D location in 2012. We are expanding our sales presence through a larger network of improved distribution channels, and are developing and targeting our products for specific geographies, particularly within our Solar Energy business. A more disciplined approach to our R&D process is being introduced, in order to effectively design, target and release our products to our customers in a much more timely fashion. This will enable us to add some new products to our portfolio in each business unit to better address customer and market needs and expand our TAMs.
Apart from utilizing our cash to buy back stock, we will continue to invest in ourselves and also actively seek out products and services that fit into our strategy and can accelerate EPS growth. We are well on our way to changing our approach to cost and customers and looking at new ways to grow and expand our business. Although we are in the midst of difficult times, the actions we have put in place to reduce operating costs, expand gross margins, accelerate growth and reduce dilution should put us in a position to significantly enhance shareholder value. We look forward to updating you again on our progress next quarter.
Now I'd like to turn the call over to Yuval who will walk you through the Thin Films business unit. Thank you.
Yuval Wasserman - President, Thin Films
Thank you, Garry.
Turning to slide 9. As expected, our Thin Films business faced challenging market conditions in the fourth quarter, driven by a decline of capital investment in our end markets, Certain markets, such as Flat Panel display and PV Solar equipment, experienced more significant declines than others, while sales to the semiconductor industry were higher than expected. Although sales down 10% sequentially, the fourth quarter saw a pickup in demand from semiconductors OEM towards the end of the quarter. This led to a slightly different composition of sales in Thin Films revenue than originally anticipated, but still in line with our overall revenue target. In total, the Thin Films business unit revenues decreased 29% sequentially to $54 million, or 48% of total sales, and Thin Film operating income decreased from $16 million to $7 million, or a 13.5% operating margin.
Turning to slide 10. We accomplished the fourth quarter restructuring goals we laid out last quarter and implemented the initial phases of our strategic initiatives. First, we combined buildings at our Fort Collins headquarters, by reducing 56,000 square feet from space utilization and streamlining operations. Second, we accelerated our localization plan by establishing a local R&D lab in San Jose, California. Now, we are fully staffed and fully operational. This lab is already seeing early signs of success, as we improve our customer engagement model to increase development speed and reduce cycle times. We also expanded manufacturing at our Korea facility, adding high-power matching network manufacturing to our locally made high power RF generators. These products will be showcased at the upcoming SEMICON Korea show, where we have an opportunity to further promote our growing local presence.
Third, we introduced the latest extension of our Paramount RF generator family, the Paramount VHF, which we also launch at SEMICON Korea. The Paramount family is our platform-based approach to product design, incorporating best practices in design for manufacturing which we believe lays the foundation for AE's future premier RF power delivery offerings. Beyond improvements in production efficiencies, customers benefit from a more flexible, scalable platform that simplifies integration as their process technology needs evolve. The new Paramount VHF has the potential to expand our market presence and SAM by 2014, and has already began shipments to a major semiconductor OEM.
Lastly, we demonstrated our superior technology and customer focus through additional design wins in dielectric and conductor etch for semiconductor applications, as well as deposition processes in non-semi applications, leveraging our Paramount, Navigator and Ascent products. These wins include new peak placements on OEM tools used in the growing AMOLED application space in flat panel display.
Looking at 2012, the environment for Thin Films is mixed, as our non-semi markets continue to struggle at low points in their CapEx cycle. The PV solar panel market remains slow, especially in crystalline silicon, while the industry awaits some price stability and consolidation. CapEx in the flat panel display market is facing ongoing cyclicality, and even the service business is experiencing some pressure, driven by a lower semi conductor fab utilization rates. On a positive note, the weakness in semiconductor OEM demand we experienced at year end has been less severe than was anticipated and has extended into the first quarter, leading us to believe that our sales to semiconductor OEMs will improve sequentially. This is due, in part, to the build out of sub-32 nanometer capacity purchases, driven by TSOC and Samsung. The current semiconductor CapEx outlook for 2012 is anticipated to modestly decline, although visibility remains somewhat cloudy.
Throughout the cycles, one of AE's competitive advantages is the relationship we have with our major OEM customers. We continue to work closely with our key customers, investing in power solutions that help move their technologies forward. These include 3-D device architecture, 450 millimeter wafers, and sub-32 nanometers in semiconductors. In non-semi applications, these include progress in thin films solar technology, in Gen 5.5 N8 in flat panel. Our investment in these technologies and the introduction of new products should expand our addressable market. Additionally, by implementing a new process of collaborative design with our customers, we jointly develop and target new products and technologies for thin films and non-thin films markets, decrease development time and cost and accelerate time-to-market. We also plan to drive more advanced capabilities from our manufacturing facility in China, while increasing operations efficiency.
I would now like to turn the call over to Gordon to discuss our strategic plan in the Solar Energy business unit and our outlook going forward. Gordon?
Gordon Tredger - EVP - Solar Energy
Thanks, Yuval.
Since starting with Advanced Energy in early December, I've had the opportunity to meet with a number of our customers and channel partners at industry events, such as the CanSIA conference in Toronto, and also to visit some of our customer sites. What has impressed me most is the high quality and reliability of our products and services, which have led to AE's strong reputation among customers and position in the solar inverter market in North America.
Turning to slide 12, our results in the Solar Energy business were strong, with another quarter of growth, with revenues increasing 12% sequentially to $58 million. During the quarter, we shipped 223 megawatts versus 202 megawatts in the prior quarter. PD powered and solar products over 250 kilowatts drove the majority of our revenue, and we achieved breakeven on an operating basis, with operating income of $231,000, despite the inevitable disruptions associated with our restructuring efforts during the quarter. But to reiterate what Garry has mentioned, we do not see this as an acceptable level of financial performance for the business and are committed to ongoing improvement.
Turning to the industry, the solar market faces myriad challenges. The expiration of the cash grant portion of the US tax program at the end of 2011 spurred some growth for us in the industry, though clearly not the sharp increase that was seen last year in the fourth quarter. Developers are delaying projects and panel purchases until the last possible moment, in order to take advantage of the ongoing decline in panel prices. This has increased pressure on inverter manufacturers to shorten our lead times. We believe that we might see a delayed benefit from some of these projects that began toward the year end, because inverters are typically the last piece of the system to be delivered for installation.
Turning to slide 13, despite the industry dynamics, we undertook several significant restructuring actions in our Solar Energy business during the fourth quarter, in order to execute on our plan to reduce costs and to position us for increased sustainable profitability in the future. First, we restructured the organization through a reduction in force in early December, and substantially completed the consolidation of some warehouse facilities which will result in further cost savings in the first half of this year. Next, we began the transition of sub-assembly manufacturing to our manufacturing site in Shenzhen, China. Having completed the planning stages, we are beginning the qualification build for the sub-assemblies in February, and plan to start incorporating them into our products during the first half of the year. The next key piece of our plan is to localize our supply chain for these sub-assemblies in Asia. Because the cost of materials for our inverters is so much greater than the direct labor and overhead cost components, improved material sourcing represents a very significant potential for us to lower our costs substantially.
In conjunction with these actions, we also reviewed our product portfolio and have taken steps to re-engineer the existing product line, allowing us to ship higher margin products to our customers. This resulted in a charge to write-off inventory this quarter, which Danny will discuss shortly. In keeping with our strategic plan, we also expanded our efforts to solidify our market positions and key relationships by getting closer to our customers. Despite having one of the broadest and highest efficiency product portfolios designed for the North American market, gaps remain. We are continuing to add new products to our inverter portfolio to address the growing needs of our customer base and to expand our market focus. For example, the 500 kilowatt mono polar inverter that we announced early in the quarter allows us to serve an important component of the commercial and small utility market in North America. This is exciting for us, as it positions us more effectively in a market that is estimated at $500 million in 2012. We expect to begin shipments during the first quarter of the year. And finally, we have begun to expand our global distribution network in targeted geographies. This quarter, we opened a new sales office near Toronto, which will provide local support to customers in the Canadian market, as that market ramps this year. And as the year progresses, we will enter other geographic markets as well.
Our pipeline is strong as we enter 2012, and we remain optimistic about our growth for the year. But as we look ahead, the first quarter of the year is always a challenging one. We anticipate winter seasonality in the first quarter. Our prospects are strong, but competition is intensifying in North America as large players look for an opportunity to participate in this fast-growing market. We are fortunate in having products that have been designed to meet the needs of our customers in the US, and combined with our strong customer support, we are positioned to compete effectively. A strong focus on costs, quality and the performance of our products, as well as maintaining strong customer relationships, will be crucial to our success. Our goal is to build a profitable, sustainable solar energy business focused on delivering the highest value for our customers.
I would now like to turn the call over to Danny to discuss our financial performance. Danny?
Danny Herron - EVP and CFO
Thank you, Gordon.
During the course of my remarks, I will refer to both GAAP and non-GAAP measures. Non-GAAP measures exclude the impacts of the $4.2 million restructuring charge recorded in the fourth quarter. Reconciliation of non-GAAP income from operations and per share earnings is provided in the press release tables.
Turning to the fourth quarter financial highlights on slide number 14, revenues declined 12.5% sequentially, and 24.3% annually, to $112.5 million. Non-GAAP EPS was $0.01 per share, which excludes the restructuring charges of $4.2 million. During the quarter, we repurchased 1.7 million shares at an average price of $10.26 per share. We ended the quarter with a strong balance sheet, including $143 million in cash, after spending $18 million on repurchases.
Turning to slide number 15, Solar Energy revenues increased 12.3% for the fourth quarter to $58.1 million this quarter. Thin Films revenue drove the overall decline, falling 29.1% sequentially, to $54.4 million. Capital spending in the Semiconductor market pulled back again this quarter, though a pick up by key OEMs at quarter's end led to a smaller than anticipated decline of 8.9% sequentially, to $26.9 million, in Semiconductor revenue. Across our other Thin Film markets, however, weaker than anticipated industry dynamics balanced out the slightly better performance of Semiconductors. The Solar Equipment market, in particular, fell off significantly, down 71.3% to $4.2 million, as the market for crystalline silicon came to a standstill. Our Service revenue saw a combined commensurate decline with Semiconductors, falling 12.9%, to $11.8 million, as fab utilization remained low and customer spending levels conservative.
Solar Energy sales represented greater than 50% of our sales. We saw some increase from the expiration of certain aspects of the 1603 legislation, but given the delay in developments in panel purchases, this led to a more moderate sequential increase than we saw last year. We continue to work through the process of restructuring various areas of our business and are pleased with the progress we have made thus far. In Solar Energy, a key piece of this equation will be the re-engineering of our products, utilizing more readily available commodity parts rather than single source parts. Having begun this effort during the quarter, we uncovered some obsolete inventory that will no longer be used in our current product line. Therefore, we have taken an inventory write-down of approximately $1.3 million this quarter.
We continue to manage our operating expenses which grew 7%, to $36.7 million this quarter, up from $34.1 million last quarter. But this is an improvement from $39.9 million a year ago. R&D expenses decreased 18.2%, to $14.4 million, representing 12.8% of sales during the quarter, as a result of our restructuring efforts. SG&A expenses increased to $22.3 million, or 19.9% of total sales, driven by a $4.1 million accounts receivable reserve for European customers and a year-to-date bonus accrual that was reversed in the third quarter.
Turning to slide number 16, while our markets undergo their own challenges, we are executing on our restructuring initiatives in order to lower our breakeven and increase our ability to grow revenues and expand profitably. During the quarter, we recognized $4.2 million in restructuring charges. In Thin Films, we consolidated approximately 56,000 square feet of our space in Fort Collins by exiting two buildings, primarily used as office and manufacturing space. We successfully negotiated the termination of the lease agreements such that no further payments or obligations are due. The only remaining expense will be related to moving the residual equipment into our other buildings. The closure of these buildings will result in savings of approximately $850,000 annually.
In our Solar Energy business, the workforce reduction we took in December amounted to $5.5 million in annual savings. We also nearly completed the exit of several off-site solar energy facilities, which will result in annual savings of $400,000. We redesigned our compensation structure to move directly pay-for-performance. Effective at the beginning of 2012, participation in this plan will be limited to executives and key management team members, where rewards will be tied specifically to Company and business unit financial goals. This will save approximately $6 million annually and reduce our dilution over time.
Finally, we also began the transition of the sub-assembly manufacturing of our Solar Energy products to our production line in China and localizing our material supply chain. When complete, we believe this will significantly decrease the labor and materials costs for our solar inverters. We are pleased with the progress we have made on our restructuring plan, having recognized $7.3 million of charges in the third and fourth quarters, which will result in annual cost reductions of approximately $12 million. Our goal is to maintain these cost controls and continue to look for areas where we can streamline costs, increase efficiencies and improve our margins.
As Garry mentioned, there is still work to be done. Over the next 9 to 15 months, we expect to implement the next phase of our plan, which should result in additional charges of $4 million to $8 million as we consolidate various facilities, and another $1 million in severance costs. Once complete, the two phases of the plan and other cost savings initiatives and margin improvements are expected to deliver annual savings in excess of $20 million, which exceeds our original plan of $16 million to $20 million in cost savings. During the quarter, we paid approximately $218,000 in taxes, as we adjusted our year-to-date tax calculation to reflect the impact of state tax increases. For the full year, our tax rate was 27%. We expect our 2012 tax rate to fall within the same range of 25% to 27%.
Turning to slide 17, the loss from continuing operations in the fourth quarter was $2.6 million, or a loss of $0.06 per diluted share. This compares to income from continuing operations of $7.2 million, or $0.16 per diluted share in the third quarter, and $19.7 million, or $0.45 per diluted share, in the same period last year. On a non-GAAP basis, income from continuing operations was $500,000, or $0.01 per share for the quarter.
Turning to our balance sheet on slide number 18, we ended the fourth quarter with cash and investments of $143.2 million. This was a $11.7 million decrease over September, due to the $18 million in share repurchases during the quarter. Excluding the share repurchases, cash flow was $6.3 million for the quarter. This is just one of many ways we are more effectively utilizing our cash under our new strategic plan. Trade working capital decreased by $6 million during the quarter. Inventories dropped $12.5 million, to $80.3 million. Stock option expense for the quarter was $3.2 million, and depreciation and amortization was $4 million. We remain focused on cash generation and maintaining a strong cash position.
Finally, turning to slide 19. We expect revenues to be between $95 million and $105 million in the first quarter of 2012 and non-GAAP EPS basically at breakeven. We expect to recognize a restructuring charge of between $2 million and $2.5 million related to a lease termination and the exiting of warehouse space and relocation of equipment during the quarter. This guidance reflects our view that capital spending levels in our Thin Film markets will remain soft, while our Solar Energy business experiences first quarter seasonality.
This concludes our prepared remarks for today. Operator, I'd like to open up the call for questions.
Operator
Thank you. (Operator Instructions)
Krish Sankar, Bank of America Merrill Lynch.
Krish Sankar - Analyst
Hello. Thanks for taking my questions. I had two of them. Either Garry or Danny, when you look at your Q1 guidance, I understand inverters are going to be down seasonally. Can you help us quantify how much do you think semis, flat panels, solar equipment, and inverters will be up or down?
Garry Rogerson - CEO
Yes. Obviously, the inverters are going to be down because we are in the winter. I guess you all know that. In the Thin Film, maybe Yuval can give you a little bit more color. But we have seen a pick up in the semiconductor area, but the reverse in all other areas. So, all in all that gives us a neutral experience. Let me let Yuval give you a little bit more color to the semi side.
Yuval Wasserman - President, Thin Films
Hello, Kris. What we see is a flat to slightly up in Thin Film BU, but the mix will change where the semi revenue will be a bigger piece of the total revenue, if we see the increase in semi.
Krish Sankar - Analyst
Got it. All right. And then a follow up for Danny. Danny, when you look at the full year for 2012, do you expect your inverter revenues to grow in 2012 versus 2011? And what is your view on the demand for US for overall solar installation?
Danny Herron - EVP and CFO
Krish, when we did our Analyst Day, we had shown growth in the 20% or so range on a CAGR basis. So we would still be in that ballpark for 2012. But we haven't given any specific guidance for full year of 2012.
Garry Rogerson - CEO
Just remember, when I was talking about the solar business, when I was telling you about the solar business, we were talking about sequentially. And there's going to be decent growth compared with the same quarter last year. I think we are talking in the range of near to 15%, or something like that.
Krish Sankar - Analyst
And do you have any view for US demand for 2012? Thank you.
Garry Rogerson - CEO
Again, as you well know, we have products designed for the US market. So we are in a very good position to grow. We are very comfortable at the present time, especially in the utilities and the commercial side. Utilities and high-end commercial, we are looking good. We are looking good. A lot of good prospects out there, a lot of big prospects out there. I think we are comfortable at the present time.
Krish Sankar - Analyst
Thank you, guys.
Garry Rogerson - CEO
Thanks.
Operator
Edwin Mok, Needham & Co.
Edwin Mok - Analyst
Thanks for taking my questions. First question I have is just a baseline, your cost reduction method, because on the fourth quarter, I guess you guys had some one-time items impacting SG&A. Just curious, how do you baseline your $12 million annualized savings? Would I use that as a baseline from the third quarter OpEx level? Just if you could help me on that.
Danny Herron - EVP and CFO
Well, Edwin, the $12 million is simply in the third quarter we announced a restructuring of about $6 million of annual savings, and in the fourth quarter we took a restructured initiative in our Solar business unit that increased about $5.5 million, and then we also exited two buildings here in Fort Collins, which is worth about $800,000. So that is the net of the $12 million or so of current cost reductions.
Garry Rogerson - CEO
And we very much expect that to jump again at the end of the next quarter, and then probably slow down a little, because I think by then we will have done what I am going to call the low hanging fruit. And then after that, it's all in the gross margin. It's all working on that gross margin, leveraging our Shenzhen facility, which -- a truly world-class facility. So that's when the hard work will begin. I think next quarter you will see another jump and then we get into the gross margin area. But there is still a lot we can do, and I'm absolutely sure we are going to go way past our targets now. As we dig deeper, there is clearly more to get in that -- in the gross margin.
Edwin Mok - Analyst
Great. Just to clarify one point there, so the cost savings that you guys talk about, how much of that is in the gross margin line versus operating [margin]?
Garry Rogerson - CEO
Most of that is probably in the operating area at the present time. And as you well know, that is the easier area to get at. We are now moving towards the gross margin, the manufacturing costs area, which takes more time. Actually, within our Company it is easy. It is actually remarkable what is happening. As you know, in our Thin Film business, we have always, or in the recent past, manufactured in Shenzhen and sourced in low-cost areas. Immediately we started this, we have now got the space in our facility, starting to look at the way we define the sub-assemblies that are going to be manufactured there. They are starting to move over there now. So actually, that is happening faster than I would have expected because of our true core competency in Shenzhen. But after saying that, it takes more time, obviously, than in the other areas.
Edwin Mok - Analyst
Great. And then just one further question on the solar inverter business, or Solar Energy business. So operating margin came in a little bit this quarter, how much of that is related to these one-time items that you mentioned versus actual pricing pressure?
Garry Rogerson - CEO
I'll let Danny answer. I mean, again, just to start that one off, our products have been designed for the US. We expect to get a premium in the US. We do get a premium in the US because of our products and our name, and our service.
Danny Herron - EVP and CFO
Edwin, we had the $1.3 million inventory write-off that was included in the Solar business unit. That was the impact on gross margin this quarter.
Edwin Mok - Analyst
I see. Great. And then one last question I have for Yuval. So you talk about the different end market. I was just wondering, in terms of the services and also revenue came down a little bit sequential in the quarter, is that just a function of the end market, or are we seeing some changes there? And how do you look at the service business in 2012?
Yuval Wasserman - President, Thin Films
Okay, so what we saw in Q4 is a seasonal decline in the service repair revenue. It is a shorter quarter, because of the holidays and shutdowns. But also what we saw, due to a fairly low fab utilization, we saw a decline in return of our products for repair, which both the short quarter and the fab utilization decline impacted the revenue in Q4. We saw, towards the last few weeks of the quarter, increasing returns, as we see some improvement in fab utilization. We expect to see it flattish to Q1, as Q1 is also a short quarter, because of the Chinese New Year that may also impact -- seasonally impact the quarter.
Edwin Mok - Analyst
Great. That's all I have. Thank you.
Yuval Wasserman - President, Thin Films
Thanks.
Operator
Zach Larkin, Stephens.
Zach Larkin - Analyst
Good morning, gentlemen. Thanks for taking my call.
Garry Rogerson - CEO
Good morning, Zach.
Danny Herron - EVP and CFO
Hello, Zach.
Zach Larkin - Analyst
I just had a quick follow-up on the initial questions Edwin was answering. Danny, you talked about the $4.1 million charge that we had in SG&A being more of a one-time thing. I'm trying to just think through more of a quarterly run rate on those lines. Should we be thinking more in the $18 million per quarter, with the cost savings taking us down below what we have seen in some historic quarters? Or what's maybe some brackets to put around where SG&A might fall?
Danny Herron - EVP and CFO
The one-timer for the quarter, obviously was the $4.1 million in SG&A. And then the comparison that Q3, in Q3, we had a bonus reversal that occurred, so it gives an artificial difference versus Q4. The real change is just the bad debt write-off. That was $4.1 million. On an ongoing basis, if you take our $12 million of cost savings, it's about $3 million a quarter. So if you went back to where we were in the third and fourth quarter, you could reduce that by $3 million and get you a run rate there on a go forward basis.
Zach Larkin - Analyst
Okay, thanks. That's very helpful. And then I know initially when you had talked about the future cost savings from the restructuring, that the linearity was going to be more back half weighted, due to most of them being plant close downs. Is that still an accurate way to think about the future restructuring charges as we go through 2012?
Danny Herron - EVP and CFO
I think the bulk of the restructuring charge will come near the end of 2012, the remaining $4 million to $8 million of additional costs. We will have, in the first quarter, somewhere between $2 million and $2.5 million of restructuring charges as we move some equipment out of some buildings into the new space.
Zach Larkin - Analyst
Okay. Thank you very much. And then, Gordon, just had a quick question for you with coming on board recently and also having a background in supply chain management. Just wondered what your thoughts were on any the low-hanging fruit on that venue in the renewable space, on improvements or benefits -- things you've seen as you've got your feet on the ground?
Gordon Tredger - EVP - Solar Energy
Thanks. I haven't had a chance to quantify any projected savings from the localization efforts that Garry discussed earlier. But obviously, it is critical for us to get the sub-assemblies that we plan to transfer over to the Shenzhen factory bedded down. And as I said in my earlier remarks, we anticipate to be commencing build in Shenzhen starting in February. So once we've got those builds underway, we are going to begin the task of looking to localize the components for those sub-assemblies in the local area. And we are fortunate to be able to leverage the existing infrastructure in Shenzhen to do that.
Garry Rogerson - CEO
To throw a rough number out to you, on the Solar business, about half of the components that we get are from high-cost areas at the present time.
Zach Larkin - Analyst
Okay, thanks. That's very helpful. Thanks for the color there Garry and Gordon, and congratulations, guys.
Garry Rogerson - CEO
Rough. I want to make absolutely sure, that's a rough number of the components. But there's a lot we can do in the component area to reduce our costs. The reality that the labor in any of these products is pretty low anyway, so you don't get the substantial saving there. You get it in the supply of the components. Again, as Gordon quite rightly said and we have said many times, that Shenzhen facility is just our little -- it's a little gold mine for us.
Zach Larkin - Analyst
Understood. Thank you very much.

Mark Delaney - Analyst
Hello. This is Mark Delaney calling in for Jim Covello. Thanks very much for taking the question. I was hoping first you could talk a little bit more about your outlook for the inverter business. Revenues were up 12% year-on-year this quarter, which is still well below your target for 20% to 22% CAGR. I was hoping you could talk about, first, what you expect needs to happen to get back onto that target growth rate, and then subsequently, if you have any view of when that might occur?
Garry Rogerson - CEO
Firstly, I think I mentioned a number of roughly 15% in the third quarter, growth in our inverter business. And we expect that to accelerate through the year. I also said that in the utility area, we are seeing some strength. And we are well-positioned with our products, as you well know, in the US. So we have plenty of room to grow.
On the other hand, I want to make sure that we are focused on making money. So we are not going to go for anything. We will go for business that fits our products. I want you to be a little bit careful there.
Mark Delaney - Analyst
Okay, that helps. How much does the competitive environment play into this? I know you've talked about, in the past, some of your customers offering irrational pricing, and then also having some balance sheet concerns of their own. Do you see any change to the competitive environment in the next couple of quarters?
Garry Rogerson - CEO
Firstly, I would never, ever say our competitors have irrational pricing, because I don't actually know why they do whatever they do. But what I can see is that we are doing quite well in our pricing because of the type of products that we have. Obviously, there are other competitors coming into the US at the present time. But again, our position is really good. We've judged it well. We have great products for the US market, for the Canadian market. We are in a nice position, so we should be able to hold our own.
Mark Delaney - Analyst
Okay. And then just lastly from us, the outlook for the semi equipment revenues in the first quarter. Do you expect your sales to grow in line with, above, or below your key customers' shipments? Thank you.
Yuval Wasserman - President, Thin Films
We project our revenue for semi market in Q1 to be in line with our customers. And what is expected in the -- if you look at the average picture from the analysts and what we hear from our customers, we are in line with that growth.
Mark Delaney - Analyst
Thanks, guys.
Yuval Wasserman - President, Thin Films
Thank you.

Mark Bachman, Avian securities.
Mark Bachman - Analyst
Hello, gentlemen. Gordon, was wondering if you can talk about how much of your backlog for inverters here in the US is aligned with projects used in Chinese modules?
Garry Rogerson - CEO
That would be a really difficult one for us to answer at the present time. Obviously, as the year goes on, the amount of modules that are in those products will increase. Again, to say that it's mainly the commercial utility where we are focused. And the Chinese modules will come in over time. We have said to you that roughly 50% of the components are sourced locally here. We have said to you that we will start -- that we are starting to make modules in China, starting in February of this year. They won't ship for a few months after that, obviously. But we are starting to make those modules there. So as the year progresses, you will see more and more of the product coming out of China and being assembled in the US in our Fort Collins and Bend facility.
Mark Bachman - Analyst
Let me try and be a little bit more specific on this. What I was looking at was the actual solar modules themselves. In other words, I think it would be very easy for you to look at your backlog. We all know that you are involved with the Mesquite project. So my point being is, how are you weighing the risk here of the ongoing trade war between US and Chinese solar module manufacturers versus your backlog and the ability for this business to be disrupted, if indeed these huge tariffs are put on the Chinese module manufacturers?
Garry Rogerson - CEO
Firstly, I apologize for not answering your question the first time. And I'm going to have to apologize for not answering it the second time. Because it is all politics, and we are staying out of that one. So I have no answer for you. My apologies.
Mark Bachman - Analyst
You wouldn't be able to estimate how much of your backlog is aligned with Chinese module manufacturers, given the fact that you have some visibility into your utility pipeline?
Danny Herron - EVP and CFO
That would be a hard number to estimate, Mark. The on the ground salesmen might know what panels are being used. But that is not anything we would ever track here in a database level.
Mark Bachman - Analyst
Okay. And then, Gordon, you had made mention -- I think we all understand the winter seasonality in the solar business here, but you also mentioned competition is increasing. Where does this now put your assumptions, then, for ASP declines on the solar inverter part of the business? Did it stay the same? Did it get worse? How should we think about this now, the fact that you are raising the increased competition flag here now?
Garry Rogerson - CEO
Just again to say, we will sell our products to customers who need our products. And we are designing into their requirement. Yes, there's pricing pressure, as there is on all product lines. But we don't see it as the biggest issue for us by a long way. Other companies do their thing, and we will let them do their thing. That isn't the reason our pricing is what it is. We are not driven by the competition.
Mark Bachman - Analyst
Okay.
Garry Rogerson - CEO
I think, again, we've got to think about the way we are. We are in a really good position. We are sitting here with products that have actually been designed for this country, in the utility space. And we have the utilities coming to us and wanting to buy from us. These projects take a long time, there are long lead times on them, but we are in a great position to sell to the utility marketplace, and the high-end commercial. We are also releasing a new product, which I think we mentioned, the 500, which fits the commercial market beautifully, and gives us another, I think, another $500 million of TAM, am I right, Gordon? So we are expanding our market another $500 million when we start taking orders for these products this quarter and start shipping next quarter. So we're in a very nice position. I think a lot of the companies that you refer to would love to be us.
Mark Bachman - Analyst
Okay.
Garry Rogerson - CEO
And we're not, by the way, we are not in the shrinking areas. We are not in Europe. We are not in these areas that are having difficult times. So we don't have to battle the shrinkage that is obviously occurring in those areas.
Mark Bachman - Analyst
I take it from that comment then, that despite everything that's going on in the US solar market, that you still expect it to grow at this point, that you wouldn't classify it as a shrinking market.
Garry Rogerson - CEO
It absolutely is not a shrinking market. I think I mentioned, or Gordon mentioned, 15% growth this quarter compared with the same quarter a year ago. I think we are looking for accelerating growth through the year. I think I mentioned that the utility market looks good for us. We are releasing new products. At this moment, we are excited.
Mark Bachman - Analyst
Okay. Let's see. Danny, just one last question from me. You had made a comment that you had exited several off-site solar facilities. I just don't understand what that means. Can you just clarify that a little bit more, and maybe -- (multiple speakers)
Danny Herron - EVP and CFO
We had nearly exited. We had a couple of off-site warehouses, Mark, that we basically stopped using them as receiving facilities in the fourth quarter, but we didn't get all the materials out. So that will occur here in the first quarter. All of the materials will be transferred to our plants and we will no longer have these off-site facilities. Which, as you know, there's nothing good about having inventory off-site. You just have to handle it twice, you have to count it twice, you sometimes lose it or damage it, taking it to the plant. So we will be out of those by the end of the first quarter.
Mark Bachman - Analyst
Got it. So these weren't like isolated groups of engineering folks then?
Danny Herron - EVP and CFO
No. They were off-site storage facilities.
Mark Bachman - Analyst
Okay. Thank you so much.
Garry Rogerson - CEO
And all we're doing is putting that -- all we're doing. Two things we're doing. One, we are reducing the amount of inventory we've got. Clearly, you can see that we have an abundance of inventory. And then secondly, the inventory we have needs to go on the floor in the factory.
Mark Bachman - Analyst
Thank you so much, gentlemen.
Danny Herron - EVP and CFO
Thanks.
Garry Rogerson - CEO
Thank you.
Operator
Timothy Arcuri, Citi.
Timothy Arcuri - Analyst
Hello, guys. If I look at the ASP in the inverter business for Q4, it was about flat sequentially, $0.26, roughly. And it's been there for the last three quarters. So there's not really a lot of realized pricing pressure in that business. I know there's a lot of mix issues. But it seems a little odd that pricing or that dollar per megawatt wasn't down a bit. If you look at SMA, they missed on margins because of pricing pressure. So is there some competitive dynamic where the US is just holding up that much better; it's just is that less of a competitive market here toward the end of 2011? And does that argue that you're going to see them come pretty heavily into the market in 2012?
Garry Rogerson - CEO
Let's say it again. We have products that fit the US market in the utility and the commercial space. Therefore, we expect to get reasonable pricing for our products. If someone comes in with products that don't quite fit, as you well know, we all know, your pricing drops. That's what happens. We are not going to do that. We're not following the market. We're trying to become a profitable organization. We've got great products, great fit. Let's keep working it. Obviously, we're going to drive our costs down. Obviously, over time, prices go down with any product of any type, anywhere, pricing goes down, and we will drive our costs down faster than the pricing goes down. But we just have products that fit. Our customers love us.
Timothy Arcuri - Analyst
Great. Just on that point. I think you alluded at the analyst meeting to potentially, in your effort to improve your profitability in that business, to potentially be willing to walk away from some business this year. Yes?
Garry Rogerson - CEO
Yes.
Timothy Arcuri - Analyst
So as pricing does get more aggressive, can you go through what your expectation is for the size of the market this year? If you back into your share in 2011, it was on the high end of your number, it was probably in the 30% range. But what is the size of the market this year you are banking on? Because it seems like your share is probably going to come down a bit.
Garry Rogerson - CEO
It will be interesting to see if our share comes down a bit. Let's see what other people say, I suppose. And then you can tell us if our share comes down. Again, we expect a nice growth rate this year. We expect to become more profitable. Well, it's not hard to become more profitable, actually. We've got to become more profitable this year. That's what we are doing.
I am not really worried about our market share at all. The key here is to grow and grow profitably. So my focus, our focus isn't on market share. After saying that, we are doing very well in the commercial and the utility side, and there are a lot of prospects. So I am pretty excited. There are a lot of big prospects out there, as you know. I think we are well-positioned. We will find out as time goes on.
Timothy Arcuri - Analyst
Okay. And then just last thing from me, if you look at the semiconductor, the big OEMs, it seems like shipments will be back up to near peak levels in June. I know you don't want to talk about June, but is there any reason why your revenue, relative to what you were shipping back at this last peak, shouldn't be back up in the semi business close to that, if that indeed turns out to be the case for your customers, which would put you like in the mid-40 in June?
Yuval Wasserman - President, Thin Films
Tim, we expect to trend exactly with the market we serve. We are well-positioned, and we have been trending with the market in Q4 in semi. We expect it to do the same in Q1 and going forward.
Garry Rogerson - CEO
Just in a caveat to that, we think we will move with the market in Thin Film Semiconductor. But please remember, Flat Panel Display, please remember the Thin Film Solar. The Thin Film Solar, in particular, is absolutely down to virtually zero.
Yuval Wasserman - President, Thin Films
Correct.
Garry Rogerson - CEO
So when we are talking about the semiconductor, semiconductor isn't our Thin Films business unit.
Timothy Arcuri - Analyst
Yes, of course. Thanks.

Colin Rusch - Analyst
Thanks so much. Can you guys just break out how much of the solar inverter revenue was related to the 1603 safe harbor commitments that were made at the end of the year for any of your customers?
Garry Rogerson - CEO
A little. Very little. I want to break it out, but very little was, as a percentage of the whole. Not significant, really.
Colin Rusch - Analyst
Then, can you just walk us through the logic, with stable pricing on an average across the solar inverter business, why take the inventory write-off? And if you could relate that back to what you're seeing in terms of mix between the PV powered and Solaron business going forward?
Gordon Tredger - EVP - Solar Energy
Excuse me. We took the write-off, and it was associated with the re-engineering of one product line. So we decided that we had a more - a lower cost product that had better features and decided that we would -- it was a better business decision to take the write-off and focus on shipping the better product with the higher margin.
Colin Rusch - Analyst
Perfect. And can you just give us a quick update on the product development for the LED market? You had made some noise about that about six months ago. Is that still a focus, something that we should be thinking about as impacting the next couple of quarters of business?
Yuval Wasserman - President, Thin Films
We continue to develop products for the LED market. In the high brightness LED, we have products in the thermal instruments area that serves the market. This market took a significant decline, as there was a huge over capacity of LED or high brightness LED, and the equipment sales for this market are expected to drop 70% to 80%. So that is something that will continue in the background.
In the flat panel display market, there is significant investment in AMOLED applications, as Samsung and others continue to push forward to develop the next generation displays based on AMOLED technology. For these applications, we continue to gain share and win applications for both etch and deposition technologies, where our power supplies are critical for the manufacturing process. We expect to see significant growth in the future in AMOLED for flat panel displays and to leverage that growth in our business.
Colin Rusch - Analyst
Great. Thanks a lot, guys.
Danny Herron - EVP and CFO
Thanks, Colin.

Joe Maxa, Dougherty & Co.
Joe Maxa - Analyst
Thank you. I was just going to ask a little more about those flat panel display, and even the industrial side where your sales have been low, and what your outlook is going forward.
Yuval Wasserman - President, Thin Films
We expect to see, during 2012, there's a decline in the flat panel display area. And a lot depends on the timing of Samsung next investment in their investment cycle, as they continue to build capabilities for AMOLED devices, as well as next generation technology for transparent displays and flexible display. We are very closely working on making sure that our products are designed into these applications. The timing of the growth is still murky. Depends on Samsung's investment decisions.
Joe Maxa - Analyst
And how about on the industrial side? That has been right around the $10 million or $11 million per quarter for several quarters, and had a drop off here in 4Q. What should we be thinking about that product line?
Yuval Wasserman - President, Thin Films
You can look it as going forward it will be flat.
Joe Maxa - Analyst
Okay. And as far as the solar panel being basically zero, are you looking at it really getting down to that level, or are we just going to bounce around a $1 million, $2 million, $3 million, $4 million a quarter? Is that kind of the outlook?
Yuval Wasserman - President, Thin Films
I think it will continue to be at the same level through 2012. Our main focus right now during this year is there is a huge over capacity of panels as well as equipment, is to continue to work on increasing our content in Thin Films, especially in the [VIGS] area, where we believe we will see growth in the next few years.
Joe Maxa - Analyst
I see. Danny, got one for you. Where should we be thinking about gross margins for Q1? And as we move through the year, I would expect them to go up, but what should we be thinking about in Q1 with lower revenue?
Danny Herron - EVP and CFO
Obviously, Joe, we don't forecast the gross margin on this, but you have a seasonal mix. In Q1, we will be a little bit more Thin Film than we were inverters in Q4. So you should get some improvement in Q1. But over time, it is a mix of our two business units that drive that.
Garry Rogerson - CEO
Bearing in mind, costs tend to be lower in the fourth quarter than the first quarter. So we got mix consideration, and you've got a seasonal cost consideration, because there was a lot of time off in Q4, compared with Q1.
Joe Maxa - Analyst
Okay. All right. Thank you, guys.
Danny Herron - EVP and CFO
