Hans Betz - President & CEO
Good afternoon, everyone, and thank you for joining us. After a difficult end of 2008 , the first quarter of 2009 fell further. Despite the strides we made toward achieving a more diversified revenue stream, able to weather single industry events or downturns, the extensive nature of the credit crisis and resulting economic conditions have affected all of our markets simultaneously. This leads to a further declines in weakened semiconductor markets, a pause in solar equipment purchases as financing dried up and the industry awaits news of the stimulus package, and a halt to flat panel capital expansion as consumer spending remains weak. In these markets, the impact was significant and the decline precipitous.
Advanced Energy responded to the challenge and demonstrated its ability to consistently execute and maintain its market position even at these levels. We achieved our guidance for the first quarter with sales of $32.6 million and loss per share of $0.39 before the writeoff of goodwill of [$1.9] on a GAAP basis. We ended the quarter with a strong balance sheet with a cash position of $173 million including our optional rate securities. Semiconductors continue to be the hardest hit market.
Demand fell to record lows during the quarter, reflected by order declines over the previous year quarter of more than 50% from our major customers. Throughout the first quarter, OEMs worked through and scrapped the inventory at levels not seen before. And implemented prolonged and more frequent shutdowns of the manufacturing facilities in order to manage costs in this period of historically low sales. Major OEMs are reconfiguring their work in progress and finished goods inventory to conserve cash by utilizing the inventory for ordering parts of the systems very selectively one at a time. This change in purchasing behavior has created abnormal demand based primarily on a minimum amount of parts needed and had a ripple effect on suppliers such as Advanced Energy.
There is some good news, however. According to the recent earnings calls from key customers, we have heard that shipment will increase in the second quarter. In addition, we have seen some quarter activity return in our service business which is a leading indicator of market stabilization. Taiwanese have recently called some of the workforce back to work, resulting in effect, utilization of about 70%. We are cautiously optimistic to see if this is a small pause in the downcycle or the beginning of the turnaround.
Advanced Energy, nonetheless, remains committed to our strategic initiatives as we continue to see the unique opportunities to gain market share during this downturn. Despite the difficult environment, we are investing in and developing new products and technology to enable the transition to the next generation of [system] requirements for several of our markets. The most recent example of this was the introduction of our Paramount RF-Power platform. Paramount addresses multiple applications in semiconductors at the sub-45-nanometer node. We believe it is the most accurate power system on the market with ultra-high speed tuning and fast response time. Paramount is gaining traction with strong performance in preliminary evaluations that have led to some notable design wins to date. We view this product as a key strategy for the semiconductor market and believe it will position us to gain market share going forward.
Moving to the non-semiconductor markets, let me begin with solar which has been a highlight in recent quarters. This quarter, however, even thin-film solar could not escape the widespread impact of the credit crisis. With winter the seasonal lull for panel installation, the sudden decrease in availability of financing, slowed expansion and investments exacerbating the conditions and causing overcapacity. Advanced Energy's decline in solar sales during the quarter reflected all of these factors. Similar to the semiconductor market, we are seeing a change in solar equipment order patterns. We are now seeing the emergence of equipment suppliers to the solar industry offering discrete processing equipment solutions. Additionally, areas such as Europe and China, who are leading the green tech movement and receiving government funding, are continuing to press on and expand capacity.
We are seeing a significant portion of our business come from newer well-funded entrants and recent design wins. As such, we expect these companies to continue to make purchases from Advanced Energy in the near future. We anticipate that the US stimulus and tax incentive programs surrounding solar initiatives will also positively impact our solar business.
In inverters, we continue to penetrate the large commercial and utility markets this quarter with sales of the first three 500-kilowatt Solaron inverters. Similar to our 333-kilowatt inverter, this product is performing at the highest efficiency rating on the markets, 97.5%. Our Solaron inverters continue to prove their merits and set industry standards, evidenced by our second award for technologic innovation over the last six months from the EE Times who gave the Advanced Energy the Most Innovative Renewable Energy Award. As a relative newcomer and innovator in this market, Advanced Energy is applying its unique power conversion technology to the high-end inverter market.
In keeping with our strategy of serving large power markets, we have chosen to target the large commercial and utility markets, rather than the traditional inverter market comprised of residential and small commercial customers. As the high power commercial inverter market is a much newer and developing market, these customers have distinct needs and requirements which cause the market to behave differently with long sales cycles and trial periods, as well as the need for financing. However, the potential for sizable orders and repeat customers is also greater. Also, this market is not immune to recent financing issues. We believe the strength of these companies' balance sheets, combined with the stimulus package and related tax incentives targeted at the solar market puts them in a strong position to benefit.
The flat-panel display market continues to have its difficulties, none of which to be resolved in the near future. The first quarter represented the tail end of Gen 8 investments, begun in 2008. We do not expect the subsequent wave of investment to occur for some time, most likely in 2010. Inventory levels have improved and display prices stabilized during the first quarter. Though the capital constraints in this market will restrict any major capacity expansion until consumer spending returns. There are, however, some interesting opportunities for upgrades to enhance the performance of the installed tools. Other markets, such as Taiwan and China, must find a way to obtain investment of their [fabs] in order to make the move to Gen 5 and Gen 7 panels or risk closure or obsolescence. As these countries appear unlikely to let this happen, there is potential for governmental intervention in these markets, and we will watch closely as it unfolds, especially in China.
Moving on to our service business, with such precipitous declines in semiconductor and flat-panel sales, service, too, felt the significant impact of the downturn this quarter as well. As a key part of our support strategy, we anticipate that service will be a leading indicator for recovery in our markets. Recently in an effort to preserve cash, semiconductor [FABs] have drawn on existing under-utilized machines for their spare parts and repair needs, causing revenue to fall to extraordinarily low levels. With indications that [FABs] utilization began to increase in the first quarter, the repair and tune-up of the idle equipment on the [FAB] floors should begin. Given what we believe are the limited supply of spare parts on-site at the [FAB] semiconductor manufacturer will need to order these parts to replenish their stocks, driving service revenue in the near-term.
Finally, our other business lines -- glass, data storage and industrial applications suffered similar, albeit smaller declines in the quarter. With the growing focus on and investments in solar-alternative energy, government stimulus packages in various geographies may play a key role potentially in the industrial coating and emerging markets. We expect the industrial market to be among the first to recover given the shorter lead times for capital investment in this collection of diversified industry. Serving as a barometer for consumer markets, this fragmented group of customers has long supply chains that make industrial coating for a variety of products. Therefore, as demand for consumer electronic product grows and buying capacity increases, manufacturer will expand capacity for existing technology or implement new or next generation technology, in addition to starting up the idle equipment which will likely be in need of repair or spare parts.
As we commented on our last earnings call, we anticipate the weak economic conditions to impact Advanced Energy and our reserves markets for the remainder of 2009. We are using this downturn as an opportunity to examine each of our markets more closely and confirm our technology roadmap in each of our markets. We are proactively taking steps to fine-tune our strategy, maintain our strong financial position, and prepare for fundamental changes to the equipment industry.
First, as we have shown in the last quarter and the last year, our focus on maintaining our strong cash position continues to enable us to have the ability to drive our future business strategy. Additionally, we will continue our investments into next generation products such as our Paramount RF generator for [framing] semiconductors and [Zendt] DC generator for large area [centrum] applications in particular flat-panel, solar panel, and in commercial inverter applications. In order to reinforce our partner and customer relationships and prepare us to gain market share even as markets return slowly.
Finally, we will improve our operational discipline in order to minimize our overall cost structure and breakeven, positioning us for profitable growth and margin expansion opportunities in the future. So our visibility beyond the next quarter is poor. We have seen some positive indications that our markets may improve in the second half of 2009. We are hopeful that this begins a positive wave of capital spending that leads to a healthy recovery in our markets. We believe the early signs will come from our service business, followed by the industrial market and the solar market, which stands to benefit from the stimulus package. And finally, semiconductors which is running at trough levels. While flat-panel and data storage most likely will be among the last to recover. I would like to thank the entire Advanced Energy team around the world for their hard work. I will now return the call over to Larry Firestone, our CFO, to elaborate on our operating
Larry Firestone - EVP & CFO
Thank you, Hans. Good afternoon, everyone. I will review the results for the first quarter of 2009 and discuss our guidance. As anticipated, the global credit crisis deepened during the quarter, impacting all of our markets. This took first quarter revenue to $32.6 million in line with our guidance, but down 63.3% from the $88.9 million from the same period last year and down 51.7% from the $67.5 million in the prior quarter. Sales to the semiconductor capital equipment market represented 29.4% of total sales in the first quarter. At $9.6 million, sales declined 57.5% from last quarter's $22.5 million.
Sales to the non-semiconductor markets were also pressured this quarter. Though they remained a similar percentage of total sales at 47%, non-semi sales declined 53% to $15.3 million from $32.6 million in the previous quarter, with the largest decline coming from solar. Sales to the solar market were $6.2 million or 19% of total sales, well below last quarter's strong performance of $16 million or 23.6% of total sales, due largely to difficulties surrounding project financing.
As the first wave of investments for Gen 8 and 8.5 panels concluded, the current capital constraints are delaying the next wave of expansions. Sales to the flat-panel display market fell to $3.4 million or 10.5% of total sales in the quarter versus $6.5 million or 9.6% in the fourth quarter. Architectural glass sales represented 5% of total sales or $1.6 million, versus 3.5% or $2.4 million in the fourth quarter. Glass sales this quarter were driven largely by a shipment to a glass coating customer in China, and this equipment will be used to sell coated substrates to the solar market.
Sales to the varied industries that comprise our industrial coating and emerging markets were approximately $1.5 million, or 4.5% of total sales, down significantly from the $6.5 million or 9.7% in the prior quarter with revenue declines across regions and markets. With the capital expansion delayed until Blu-Ray media pricing comes down and the consumer market returns, sales to the data storage market represented $809,000, or 2.5% of total sales, compared to $1.2 million or 1.8% of sales last quarter. Our service business declined 37.8% from last quarter, representing approximately 23.6% of total revenue or $7.7 million, as manufacturers continue to utilize idle equipment for spare parts, conserving their cash and pushing maintenance levels to new lows.
Our book-to-bill ratio was 0.87 to one, and we ended the first quarter with $24.4 million in backlog, down from last quarter's backlog of $28.6 million. Approximately 60%, or $14.7 million of this backlog is shippable in the second quarter. Gross profit was $6.4 million or 19.6% for the first quarter, compared to $18.4 million or 27.2% in the fourth quarter. The sequential decline in margin was mainly due to decreased revenue levels and the resulting lower absorption of our manufacturing overhead. Gross profit also declined from the same period last year of $35.8 million or 40.3%.
R&D decreased 17.2% to $11.1 million, or 34% of first quarter sales. Down from $13.4 million, or 19.9% of fourth quarter sales and $13.1 million, or 14.7% of sales a year ago. We continue to invest in key emerging areas of growth while also managing costs during this period of uncertainty. SG&A declined slightly from last quarter to $9.4 million, or 28.8% of first quarter sales compared to $9.5 million, or 14.1% of fourth quarter sales. And $14.5 million, or 16.3%, in the same period last year. We expect to see further savings based on our recent cost reductions and global shutdowns.
We have implemented cost reductions throughout 2008 and into the first quarter of 2009. Since the beginning of 2008 , we have reduced our headcount by 516 people for a total reduction of wage and [French] costs of $24.9 million. The cost reductions taken in December and March resulted in a $3.4 million restructuring charge in the first quarter, and we expect to incur an additional 1 million restructuring charge in the second quarter as these reductions are carried out. Last quarter, we discussed the target break-even point of approximately $55 million exiting the second quarter. However, given our committed investments in new products and the effect of our product mix, our break-even point exiting 2009 will be closer to $60 million on a quarterly basis.
We do have additional cost reduction measures that will be implemented later in 2009 or 2010 and beyond, in areas such as facilities as we have leases that are expiring and other reductions related to efficiencies. We believe our more streamlined cost structure will position us with tremendous profitability leverage when the markets begin to recover.
We continue to record evaluation allowance on our US net operating losses, and as such, our tax rate is near zero. The $938,000 tax benefit resulted from losses in our foreign subsidiaries as they recorded restructuring charges during the quarter. We mentioned on our last earnings call that we were likely to have a goodwill impairment charge. And having completed the [Step 2] analysis, we recorded an impairment charge of an estimated $63.3 million in the first quarter. This charge increased our loss per share by $1.51 per share in the quarter. GAAP net loss was $79.8 million, or $1.90 per diluted share, compared to a net loss of $19 million or $0.45 per diluted share in the fourth quarter and a net income of $6 million or $0.13 per share in the first quarter of 2008. Excluding the goodwill impairment charge, EPS would have been a loss of $0.39 per share.
Headcount at the end of the first quarter was 1,251 employees, compared to 1,679 employees at the end of the fourth quarter. As of March 31, 2009, cash and investments including auction rate securities were $173.4 million down slightly from the $180.1 million at December 31, 2008. We consumed some of our cash in the quarter and with the lower level of sales. Trade accounts receivable dropped to $35.6 million at the end of the first quarter of 2009 compared to $56.5 million at the end of the fourth quarter of 2008, based on the lower sales volume. As a result, DSOs were 109 days, compared to 78 days in the fourth quarter. The increase in DSOs was due in part to delayed customer payments and also a high concentration of accounts receivable in Japan where standard terms are longer than in other regions.
Total net inventory was relatively flat at $46 million, and net inventory turns were consistent with last quarter at 3.8 times. Capital and expenditures were $454,000, and fixed asset depreciation was $805,000. And intangible amortization was $222,000 for the first quarter. During the quarter, we also recorded a one-time reduction in depreciation related to our building in Japan, or a $1 million adjustment through depreciation. However, the ongoing run rate will be approximately $1.8 million a quarter for depreciation.
Our guidance for the second quarter is as follows -- sales will be in the range of $30 million to $36 million. Gross margins will be in the range of 15.3% to 21.4%, and the GAAP loss per share will be in the range of $0.41 to $0.34, using the zero percent effective tax rate.
In summary as Hans mentioned, these are unprecedented times in the global economic markets. We have taken proactive measures to lower our cost structure and improve our operational efficiencies over the last several quarters and will continue to do so as needed. We have taken the necessary steps to achieve our lower break-even point of $60 million by the end of 2009, with additional cost reductions to come, which will further improve the break-even point going forward. We believe our solid balance sheet, combined with the investments we are making in new products and our core and emerging markets, will position us well as the markets improve. That concludes our prepared remarks for today. Operator, I would like to open up the call for
Operator
(Operator Instructions). Your first question comes from the line of Jim Covello with Goldman Sachs. Go ahead, sir.
Kate Kablarsky - Analyst
Hi, this is [Kate Kablarsky] for Jim Covello. I had a couple of questions. One is, you talked about the semiconductor market potentially being the last to recover as you look at all of your businesses. At the same time, we are already seeing a little bit of an improvement off of the bottom. Granted, off of a low base. But, there is some improvement. You alluded to some of your customers talking about improvement in shipments, etcetera. I was just wondering whether your comment was more about a significant improvement in business related to capacity buys? Or whether that was also related to some of the technology-related buying we are already seeing from your customers?
Hans Betz - President & CEO
I think in reality, it is both. What we see at this point in time is some kind of silver lining, but it is hard for us to derive from these kind of stabilizing effects. We have a higher service revenue. We see some year-end prices stabilizing. We see a higher FAB utility. All those indications are positive, but they are not strong enough in order to derive something very strong as a rebound from that. We are just cautiously optimistic. I think as long as no new FABs are really being announced and except the Intel FABs and the A&D FABs, we haven't heard anything around that, too. As long as it is not happening, we don't think that there is a very fast recovery.
Kate Kablarsky - Analyst
If we just think about your guidance for Q1. If you think about the various market segments, how should we think about what is doing relatively better or worse as you see it in Q2?
Hans Betz - President & CEO
In Q2, we see definitely a much better solar business, in particular coming out of Europe and China. I think, we still are very, very cautious as far as the semiconductor market is concerned. Again, we haven't seen any strong recovery in our orders from this market even though Lamm and Novellus indicated shipments up in Q2 in a pretty substantial manner, 35% and 28%. But we think because it is -- it didn't trickle down to us yet -- I think we think it is more burning through the inventory which may be a good sign. But it is not necessarily something which gives a strong indication that everything is rebounding on the semi side.
Kate Kablarsky - Analyst
That makes a lot of sense. Maybe one final question for me. You mentioned earlier in the call about taking a look at maybe re-evaluating some of your businesses. I don't know if I was reading to much into it, but I was just wondering if you could talk big picture. What you think about your various business segments? What you consider to be the really core must have areas, and what might be some less core areas of the business?
Hans Betz - President & CEO
I think maybe it was not really understood. Because we do fine-tuning our strategy in those business areas. We are not considering anything in order to be not our core or less our core business. The reason is pretty simple. If you look at, for example, the optical storage business which is kind of dragging and nobody knows exactly whether Blu-Ray is really taking off. Even if that is not the case, I think we have a platform which is being applied for for the optical storage. It is not a specific optical storage platform. It is a platform which is to be used in other areas as well. Even though if the market is not holding up as we expect, there is no kind of divestiture or something like that -- thought about that.
Kate Kablarsky - Analyst
That's very helpful. Thank you very much.
Hans Betz - President & CEO
Sure.
Operator
Your next question comes from Brett Hodess from Bank of America Merrill Lynch. Go ahead.
Chris Bancar - Analyst
Hi, this is [Chris Bancar] for Brett Hodess. I had a couple questions, too. One is, in terms of the $60 million break-even exiting the year, can you tell me how much of that includes the temporary cost reduction measures, like the shutdown and other things that you have done? Or is it all purely on a permanent basis?
Larry Firestone - EVP & CFO
It does include the temporary shutdown measures -- the temporary cost reduction measures including shutdowns and pay reductions. However, on the other hand, we have, as we mentioned, additional cost reductions that we have in the works that will replace those on a going-forward basis.
Chris Bancar - Analyst
Got it. So you can just assume it's going to be $60 million. Are there any one-time restructuring charges for 2Q '09? I remember last year you had about $800,000 -- ?
Larry Firestone - EVP & CFO
One-time restructuring charges -- ?
Chris Bancar - Analyst
What are the non-operating charges for 2Q?
Larry Firestone - EVP & CFO
2Q non-operating charges -- restructuring was about $3.4 million, and the -- .
Chris Bancar - Analyst
For 2Q, for the guidance?
Larry Firestone - EVP & CFO
I'm sorry for 2Q, that was Q1. Restructuring charges will be about $1 million.
Chris Bancar - Analyst
In terms of the solar market, you said on the inverters side you are focusing more on the commercial and the utilities market. Is there any way you can slice it up? I know last time you mentioned it roughly -- your opportunity is about $0.30 to $0.40 a watt. Is there any other market size you have available for that market?
Hans Betz - President & CEO
I think, we have been concentrating on the utility side of the market which goes up from 250 kW up to maybe a megawatt or even 1.5 megawatt. The actual size of the market is hard to determine at this point in time because it is being held back a bit because of the financial situation. I think those are projects which are pretty expensive. So what we see is, everybody is kind of sitting on the sidelines waiting until the stimulus package is kicking in. Our judgment is that we see some kind of real strong uptick in the second half of this year, just because of the fact that the administrative elements which are getting from the federal through the state and the state itself is disseminating the money. It just takes time. What is the accessible market in terms of hard numbers? I think it is hard to define at this point in time.
Chris Bancar - Analyst
And Hans, you mentioned that you still don't have much visibility into your semi [million] customers. Or, you still think that they are drawing down from the inventory. Do you have any idea as to how much longer they have to go? Or do you think they are right around the cusp of giving you guys some really solid shipments?
Hans Betz - President & CEO
This is pretty tough. Because if you look at the -- as long as the consumer confidence is pretty low. As long as people are not really buying these electronic gadgets, it is hard to see something which could be the stimulus in order to generate new FABs. Of course, some of those new FABs will be built in the course of '09 and beginning 2010 because of the technology nodes which are asking for new FABs. The big business, in my view is still -- it's capacity buys, too, not only technology buys. It is hard for me to give you some kind of credible outlook when that may happen.
Chris Bancar - Analyst
Okay. Last question in terms of flat-panel, you said the recovery you think is going to be more of a 2010 story. Do you think it is because in 2010 -- do you think the Gen 10 or 10.5 CapEx will start coming into line?
Hans Betz - President & CEO
I think there are a couple of things, too. On one side, there is the inventory on the flat-panel side is burning through. On the other side, it goes back to the same point which I mentioned for the semi side. As long as people are not buying flat-panel TVs or monitors, there is no need for building new FABs. If you recall, one of the new Gen 10 flat-panel sets is around $3 billion, and people are very reluctant to put that much of money into new FABs if there are no signs for a solid recovery on the consumer spending side.
Chris Bancar - Analyst
Got it. Thank you very much.
Operator
Your next question comes from Olga [Levenhon] from Barclays. Go ahead.
Olga Levenhon - Analyst
Thank you for taking my question. Larry, in terms of the gross margin you that saw this quarter, I think you had guided to 17%. It was around 20%. Can you talk about what drove the appetite there?
Larry Firestone - EVP & CFO
We had inventory absorption gave us a positive hit to the gross margin. It increased the gross margin, that was about $1.3 million.
Olga Levenhon - Analyst
And then the break-even level that you guided of $60 million, what gross margin does that assume?
Larry Firestone - EVP & CFO
Hang on a quick second. It will be in the mid-20%s kind of range -- I'm sorry in the mid- to higher 20%s kind of range.
Olga Levenhon - Analyst
And then on the display side, you talked about the dropoff driven by the fact that the panel makers have invested partially in Gen 8 at the end of 2008, and that they are basically holding off. How does that fit with the comments that you have recently heard from LPL and AUO about really pulling in and ramping up their Gen 8 facilities through the end of the year? Does that suggest that everything they needed in terms of your parts they already received? Or that you are just taking a cautious approach to it?
Larry Firestone - EVP & CFO
We saw some of the activity coming out the China -- coming out of that activity that you are referencing. We have seen some order activity related to that, and that will really be dropping in in the Q2, Q3 timeframe.
Olga Levenhon - Analyst
So you would expect, I guess, a couple quarters of an uptick from these levels?
Larry Firestone - EVP & CFO
Still, it is not a surge of orders. It will probably be more steady business for us as we go forward, but it is nice, new business. But it is not a surge of increase in new FAB capacity, like a cycle.
Olga Levenhon - Analyst
Thank you.
Larry Firestone - EVP & CFO
Yes.
Operator
(Operator Instructions). Your next question comes from Tim Summers from Wunderlich Securities. Go ahead.
Tim Summers - Analyst
Thanks for taking my question. Hans, in your prepared remarks, you had mentioned that you expected some markets to improve in the back half of this year. Can you identify those markets, and how much improvement you expect?
Hans Betz - President & CEO
The first thing is -- what we see already is some improvements on the solar side right now, on the [centrum] side. As I mentioned in my script, I think we expect a much stronger inverter business in the second half. Partly driven by the fact that the stimulus package may kick in, which not only the inverter market by the way will boost up, but the filter market as well. The other point is the service business which we have as a separate business. Which we see an uptick, not only an uptick, but significant improvement. This is probably going through the rest of the year because the indication is that they have been burning through the inventory, the capitalization went up. They have to order spare parts, and they have to look for repairs. These are the two major markets in which I see in the second half may improve. Again, coming back to my statement earlier, it may that semiconductors are going to improve, too. The visibility there is much, much worse.
Tim Summers - Analyst
And just on the solar business, do you have 10% customers in that market?
Larry Firestone - EVP & CFO
10% of total revenues?
Tim Summers - Analyst
Of total solar revenue?
Hans Betz - President & CEO
Total solar revenue --
Larry Firestone - EVP & CFO
Not that we -- .
Hans Betz - President & CEO
No, but we have some in the order of 5% to 8%. I think one is -- .
Larry Firestone - EVP & CFO
Probably in that range.
Hans Betz - President & CEO
But not 10%.
Tim Summers - Analyst
As you look at the customers that you sell to, give us a ballpark -- what percent are to manufacturers themselves, like AMAT, versus the actual panel manufacturers themselves?
Hans Betz - President & CEO
Most of our business is being done through the OEMs. As you know, there are two typical different OEMs. One are the turnkey suppliers like AMAT and [EarlyCon], and the others are the numerous -- in the meantime, numerous OEMs which just provide a portion of the equipment, either the deposition or maybe the measuring equipment or the laser cutter or whatever that is. We see -- in particular in China, on a daily base popping up new small players. And fortunately, by the way, we are strong in China because we have the biggest facility there. And therefore, we are kind of entrenched in this regional market, and we are benefiting from that.
Tim Summers - Analyst
Great. Thank you.
Hans Betz - President & CEO
Sure
Operator
Thank you, very much. And I would like to turn the call back over to Mr. Larry Firestone at this time.
Larry Firestone - EVP & CFO
Thank you, operator. Just as a reminder, we will be at the JPMorgan Technology, Media, and Telecom Conference on May 18th in Boston. Without any further questions, we would like to thank everyone for joining the call, and we will see you at all of our future events. Thank you
