Thank you, Sandy. Good afternoon, everyone. For Q4 fiscal year '20, net sales decreased 2% sequentially to $138 million, which was above the midpoint of our guidance. Fiscal year '20 net sales decreased 13% over the prior year, driven by the challenging macro environment the overall industry faced for much of the year, fueled by the China tariffs and Huawei ban. In Q4, shipments into Asia represented 78% of net sales. North America represented 13% and Europe represented 9%. Total direct sales represented approximately 24%, and sales through distribution was approximately 76%. Our distribution business remains balanced, with 55% of the total POS coming from the high-end consumer and enterprise computing end markets and 45% of total POS coming from the industrial and communications end markets. While bookings declined slightly over the prior quarter, book-to-bill was above 1. Turns bookings accounted for approximately 37% of shipments during the quarter. Q4 GAAP gross margin came in as expected at 61.1%, and we expect our Q1 gross margin to be relatively flat sequentially. Q4 GAAP operating expense increased 8% sequentially due to higher pension expense, share-based compensation expense and new product expense. In Q1, we expect GAAP operating expense to decrease between 8% to 12% sequentially, primarily due to lower amortization of intangibles, lower share-based compensation expense, lower pension expense and lower new product expenses. Q4 GAAP interest and other expenses increased to $3.1 million from $1.5 million in Q3, driven by the impairment of some of our minority investments and the write-off of previously capitalized debt issuance cost from our refinanced debt. Q4 GAAP tax rate was approximately 59%, up from 16% in Q3, primarily due to the impact of an internal asset transfer between tax jurisdictions. Note that there was no significant cash tax impact from this action. We expect…

Thank you, Emeka. Good afternoon, everyone. I will discuss our Q4 fiscal year '20 performance by end market and by product group, discuss our fiscal year '20 performance and then provide our outlook for Q1 of fiscal year '21. In Q4 of fiscal year '20, net revenues decreased 2% over the prior quarter to $138 million. Softer demand from the industrial and consumer end markets was offset by stronger demand from the enterprise computing and communications end markets, which contributed to better than seasonal results for Q4. We posted non-GAAP gross margin of 61.5% and non-GAAP earnings per diluted share of $0.40. In Q4 of fiscal year '20, net revenues from the enterprise computing end market increased sequentially and represented 32% of total net revenues. Net revenues from the communications end market increased sequentially and represented 10% of total net revenues. Net revenues from the industrial end market decreased sequentially and also represented 32% of total net revenues. Net revenues from the high-end consumer market decreased slightly over the prior quarter and represented 26% of total revenues. Approximately 18% of high-end consumer net revenues was attributable to mobile devices and approximately 8% was attributable to other consumer systems. I will now discuss the performance of each of our product groups. In Q4 of fiscal year '20, net revenues from our Signal Integrity Product Group increased 1% sequentially and represented 43% of total revenues. Stronger demand from the data center and base station segments contributed to the sequential growth. In Q4, demand from the data center market increased nicely over the prior quarter, led by record revenues from our CDR platforms. Strong demand for our ClearEdge CDRs used in 100-gig NRZ modules was driven by our hyperscale and cloud customers. We expect this strength to continue throughout fiscal year '21. Interest…

[Operator Instructions] Your first question comes from the line of Christopher Rolland with Susquehanna Financial Group.

Yes, just any more details on LoRa, what percentage of LoRa today is China and where did it peak out? I'm just trying to get a sense of how this is diversifying outside of China. And what gives you confidence in your outlook looking forward?

Well, LoRa used to be -- about 60% of the revenue was from China. I think it's still close to that. It's definitely diversifying now. And the opportunity pipeline has, as I mentioned, about 65% of the opportunity pipeline is outside China. So that diversification across the different regions is happening. I would say, though, that China from being a headwind for us last year continues to actually be quite strong as we look at it now. Bookings are stronger. And I think China, in general, may be the first region to kind of overcome all the coronavirus' main issues. And as we see capacity coming back online, that seems to be strengthening the demand in China. So it's difficult to call how the next year will play out. But I think going forward, definitely with the opportunities being more geographically balanced, I think we'll expect to get a little bit more of a balanced revenue geographically over the next few years here.

Great. And then your guidance, it kind of looks like it's in line with others in terms of the effects from the virus. You also called out that this was probably mostly supply chain and less about demand disruption. Maybe you can talk about the supply chain, what you're seeing there. Is it upstream? Is it downstream? And also, what gives you confidence that, that demand comes back and that there's no actual demand disruption in the end?

Yes, I would say, first of all, I don't think yet we have really seen any major supply chain issues. I think what's clear is that China, as a region, we're struggling with the coronavirus. And with the move out shift of Chinese New Year, that impacted the overall demand for sure. And it's slowly coming back online, maybe not -- somewhere around between 70% and 80% capacity, I think. So demand fully isn't there yet. But all indications prior to the coronavirus was that demand for Q1 was going to be strong. It's still remaining relatively strong, I would say. Bookings have been pretty healthy. Our turns required is fairly low compared to what we've done historically. So that all gives us a fairly good feeling. And then also, when we see the different segments we play in, we see data center strength and we see 5G infrastructure strength and we see generally infrastructural areas doing quite well, plus one would anticipate some type of stimulus, both in Asia and maybe in other countries, that will, again, impact infrastructure. So yes, we're anticipating once the demand environment settles around -- after the coronavirus kind of stabilizes, we're expecting the demand to pick up again.

Your next question comes from the line of Quinn Bolton with Needham & Company.

I guess I just wanted to follow up on that. It sounds like you haven't seen any major supply chain constraints. Bookings are starting to recover, especially in China, as coronavirus there seems to be getting a little bit more under control. So I guess, when we look at your April quarter guidance and the $10 million that you adjusted for coronavirus, where did that come from? Is that just sort of lost demand as factories were offline or just the near-term demand destruction within the China market in the month of February? Or are you anticipating potential cancellations or pushouts or something in the March and April order book that you may not have seen yet, but you're just being conservative and allowing for some potential pushouts or cancellations over the next couple of months? And then I've got a couple of follow-ups.

Yes. Quinn, it's a little bit of everything you said. Actually, it's some data points that suggest that some of the PON tenders and proof-of-concepts on LoRa being slightly pushed out. So we see a little bit of pushouts of those. We haven't seen any cancellations or revenue -- demand pushouts or revenue pushouts. We've seen more indications that things are just kind of being delayed. Clearly, there's some softness, as I said, because the Chinese New Year is delayed and some delay in just bringing up capacity in China. So that impacted it. And clearly, there is some nervousness and uncertainty around the coronavirus around the world. And so I think all of those kind of give us food for thought as we were planning our Q1 number, and we anticipate kind of approximately a $10 million impact, which is reflected in our numbers.

Great. And I just wanted to switch over to the data center market. It sounds like you're expecting a stronger year in fiscal '21. Just wanted to confirm that I heard that correctly. And a follow-up on the Tri-Edge, it sounds like you've got your first production order. So congratulations on that. Just wondering, as you look through fiscal '21 for Tri-Edge, does that ramp to any kind of meaningful level? I mean could it be a few million bucks a quarter by the end of the year. Could it be larger? Or is it kind of a slower ramp? Any sort of magnitude of how quickly you think that business takes off could be -- would be helpful.

Yes, Quinn, the -- actually, the NRZ CDRs, as I mentioned, were still -- that's doing extremely well, which suggests to us that the -- probably the PAM4 stuff will be a little bit slower. But I think one of the compelling value propositions of Tri-Edge is the lower power and lower cost. So a lot will depend on how fast the customers want to transition, I think. So -- but we had planned on a stronger kind of second half, so maybe $3 million, $4 million in the second half year -- of the year and then really ramping up next year.

Your next question comes from the line of Karl Ackerman with Cowen and Company.

2 questions, if I may. I know you guys don't want to go out on a limb and talk about a preliminary guide for fiscal '21, but I'm curious to the extent you could comment or willing to comment. It was too early to suggest that you can grow top line this year, just given the strong growth opportunity across LoRa and your data center business. And despite your view that OpEx will grow half the rate of sales, I guess, how flexible can OpEx be in the event growth turns out to be a little bit less than your current expectations? And I have a follow-up.

So let me take the revenue one, and Emeka can talk about OpEx. I mean if we look at across our portfolio, data center, I expect to still grow this year. It comes off a relatively like at fiscal year '20. We're expecting 10-gig PON to grow this year, mostly driven by China, but other regions as well. So that's our anticipation. It may not be as fast because of the coronavirus in the first half. So -- but I'd expect second half for sure. 5G infrastructure, we know, is being pushed out there, launched in every region of the world. And so we're expecting base station infrastructure to grow versus last year. Again, the timing is the quick key question. And then, of course, if we look at our IoT business and LoRa, that's -- we're still expecting that to grow. We have the pipeline. And LoRa, remember, many of the use cases, are really energy efficiency, productivity enhancements, cost reduction kind of approaches and even smart health kind of segments. So LoRa should, in many ways, still be able to grow, I think, regardless of what transpires, at least from an annual standpoint. And then in our protection business, as you know, we are slightly diversifying that business, diversifying both in the mobile area geographically and industrial area. And so we are expecting that to also do reasonably well if the general macro does well and distributors replenish on their inventory, at least again in the second half. And so pretty much across the board, we are seeing all of our product groups, we're expecting growth. Of course, a lot depends on what transpires over the next quarter here with the coronavirus. The indications are that in China, things are improving, and certainly, we're seeing that from a demand standpoint. How sustainable that is and how -- over what period of time, we'll just have to wait and see. But at the moment, I think, we're more positive than negative on it.

So Karl, with regards to the operating expenses, one of the things that we've actually been able to do very well in the history of the company is manage our operating expenses in line with what the top line is growing. One of the key things that I've always tried to call investors' attention to is that about 20% of our operating expenses is variable. And so we do have a few opportunities that we can modulate, depending on what's going on with the top line. Having said that, though, we are really very excited about some of the growth opportunities that we have within the company, the investments we're making in those areas. And so we still believe and the expectation is that those growth drivers would start to come to fruition over here and there wouldn't be any need to take any drastic actions with regards to operating expenses.

I appreciate that, Mohan and Emeka. For my follow-up, if I may, double-clicking on circuit protection for a moment. Are there new opportunities you see growing in circuit protection and proximity sensing beyond your key South Korean OEM? You had mentioned on prior calls design wins around wearables. So I was curious if you've any updated thoughts there.

Yes. We actually -- that's been a strategy of ours for a while. We've obviously been strong in Korea for some time. But a few years ago, we made a conscious decision that we're going to really go aggressively try to diversify and get smartphone business in China, smartphone business in North America, proximity sensing business as well as protection business in these areas and then look at smartphones and wearables and accessories. And I would say we've been successful with all of those strategies. I mean if I look at the business today, we have a fairly balanced geographical spread of protection in mobile devices in Korea, in China, in Asia and also in North America, U.S. specifically. And then also, proximity sensing, where it used to be just Korea, is also starting to now spread its wings into Asia and into other U.S. manufacturers and not only in smartphones, but also in wearables as well. So that is our strategy, continues to be our strategy, and we are being quite successful with that strategy.

Your next question comes from the line of Tore Svanberg with Stifel.

Let me start with a housekeeping. I think you mentioned 27% turns. Where is that number today kind of on -- more than a month into the quarter?

Tore, we can't give you that number. But what I can tell you is that the bookings have been pretty strong and we feel very good about where we are.

Okay. So it's not like you've seen strong bookings at the beginning of the quarter and those are now tailing off. It kind of just seems...

Correct.

Steady linear bookings. Okay.

Correct.

Second question on LoRa. So you gave us all the metrics for the fiscal year. Thank you for that, by the way, a lot of great information. It just seems like all -- in all the categories, there's growth. Obviously, your revenues did not grow. So can you just talk a little bit about that? I mean is this because of certain China customers going to NB-IoT? Or help us understand a little bit why your business was down, while all the other metrics were up for the year.

Yes. I think part of the thing you have to remember, which is why I mentioned it, Tore, our POS did grow 7%. So -- and that's really the measure of deployments of end nodes, right? So our revenues, when we ship them, we may count the revenue when we ship in distribution. But if there's excess channel inventory or something like that, then we may not -- you may not get the full picture. So that's one thing to remember. The second thing to remember is that the reason I give out all these metrics is to indicate momentum, and momentum is really the indicator of future revenue. When you look at how many gateways deployed, use cases, how many end nodes are being deployed or how many countries are being deployed, the assumption is that customers are going to deploy once they've completed their proof-of-concepts and they go to full implementation, they're going to deploy more end nodes and more devices, and that will drive revenue. So the timing of the revenues is quite challenging for us, especially when we had, like we did last year, one region of the world, like China, or initially really in the first half, just really struggled and kind of it was difficult to catch it up in second half of the year. We don't think that will happen this year. We think that's just going to be a little bit more stable. And we're projecting reasonable growth this year and beyond.

Very good. Just one last question. Your pipeline revenue increased $200 million year-over-year. I was just hoping you could talk a little bit about the mix of that $200 million, again, from a geographic perspective. I do appreciate that there's a much higher percentage outside of China. But if you could add a little bit more color on North America versus U.S. versus other countries, that would be great.

Yes. Let's see. So I would say about 30% is Americas. That includes North America, South America. About 36% is Europe. And then the rest is 11% -- about 11%, 12% is rest of Asia, Japan and Korea. And then about 23% is -- 25% is China, something like that. Those are approximate figures, Tore, but that will give you an idea of the opportunity pipeline.

Your next question comes from the line of Gary Mobley with Wells Fargo.

I guess as Tore was saying, congratulations to a strong finish to the year and perhaps a better-than-feared start to this current fiscal year '21. My question relates to your turns business requirements embedded in your first quarter guidance. If my calculation is correct, you're assuming roughly $10 million, $12 million in lower turns requirement for the -- embedded in the midpoint of the revenue guide. And I'm assuming much of that is related to Huawei. And so my question is, did you generate any turns business from Huawei in the just reported fourth quarter? And what's sort of the best case scenario in terms of what you can actually shift to Huawei based on the current restrictions?

So remember, Gary, so our guidance assumes no more shipments to Huawei. So we don't need any more turns to Huawei to get -- to achieve our number. Having said that, I think we plan on shipping every quarter about $10 million to Huawei. I think that's what we did last quarter...

9.5 -- $9.5 million...

About $10 million last quarter, and it's a mix of all the different products. And obviously, it takes into consideration what we can and cannot ship. And if the restriction isn't further squeezed, then we have to relook at it. But that's the reason why, as we give out our guidance, I've made the decision not to communicate that. We don't need any more turns from Huawei to make our number. So -- because we just don't know exactly what's going to happen with the restriction. As far as we're concerned, we're just assuming that the restriction will continue as it is.

Got you. Okay. And did I see a roughly $2 million restructuring in the non-GAAP reconciliation? And what does that relate to? Is that an actual head count reduction? Or are you refocusing your investment in perhaps a different area?

No, no. It's -- I think it has mostly to do with an actuarial valuation of our defined benefit obligations and a few other things. But there was no restructuring in terms of letting people go and stuff like that during the quarter.

Your next question comes from the line of Tristan Gerra with Baird & Company.

From the $10 million impact in the current quarter guidance from China, is that pretty much allocated across all the businesses you have in China? Or would you say a majority of that is actually related to LoRa? And in general, how much of a step back you think the situation in China is impacting your revenue growth assumptions for lower revenue this fiscal year?

So Tristan, the $10 million is really a coronavirus impact, and I think it -- actually majority of it is impacting our Signal Integrity Product Group, at least probably 60%. And then maybe the rest of it is split between our Protection and our Wireless and Sensing business. So it's a broad impact that we've estimated there. And then the second part of your question is, we believe that our LoRa-enabled business is going to do very well this year and China is going to come back. And already we're seeing indications of that. It may take the first quarter, as I mentioned, because of Chinese New Year and because some companies are not coming back at full capacity in China and because some of the proof-of-concepts are definitely going to be delayed because of that. And just travel and people not being able to move around in China as much is going to push out some of the activity. That's why I mentioned that proof-of-concepts and some of the new tenders and things like that may be shifted. But I don't think it changes the underlying demand or the need out there. And so that's why we feel that any loss of demand in Q1 probably will pick up, assuming things get back to normal, will be picked up in the second half.

Okay. That's useful. And then as my follow-up question, in your quarter guidance, what changes in distribution inventories are you assuming, if any? Are you assuming that inventories stay flat or on a relative basis at this stage? Or is your assumption for point of sale different from what's embedded in your guidance for disties?

No, I think it's the same assumption. POS has been doing quite well. As I mentioned, certainly LoRa is -- grew last year. And so that's a positive sign. The one thing to remember is, if the supply chain is impacted by coronavirus, and we can't get enough material or lead times extend out, I would expect our -- us to try to actually increase our inventory levels, both internally and in our channel. But at this point in time, I don't think there's any reason to do that. I think at the moment, we would expect the same type of POS and channel inventory numbers.

Your next question comes from the line of Craig Ellis with B. Riley FBR.

And guys, thanks for all the information on the call regarding LoRa and the other businesses. Mohan, I just wanted to start with a question with LoRa. First, just asking about the midpoint of this year's revenues at $105 million. As you've talked about the business potentially picking up some high-volume design wins, do you forecast that any of that type of revenue conversion would be in the $105 million? Or how do we think about when some of those higher volume wins might hit?

Yes. We're anticipating the higher volume kind of home consumer wins to be more second half, Craig. And really, they're not yet, I think, heavily in the numbers. So I would say that there's upside there. But the current numbers -- this guidance assumes continuation of the good progress in most of the smart metering, smart building, smart agriculture, kind of more longer term kind of use cases in industrial IoT and things like that. So it's still pretty good growth. But obviously, if smart home and smart consumer starts to play in, then that could impact it. And certainly, we believe that in the second half, we'll start to be able to see some of that.

That's helpful. And then the second question is really about the end points of the range. So that $90 million sales would be up about $16 million or 22% at 120 -- $46 million or 62% year-on-year. As we look at those end points, what are some of the bigger swing factors from low end to high end? Is it macro? Is it some of the high-volume items before macro? If you can just help us sort that out, that would be quite helpful.

Yes, the macro, I don't think, really plays into it other than if there's really a big shift in something like we saw at China first half of last year. I don't think that is such a huge impact. I think the bigger impact is in conversions, the POCs, the proof of concepts, the pipeline that we have, which is fairly substantial. It's converting those into deployments and real revenue. And we've already seen that, that can be pushed out sometimes. And obviously, with the coronavirus and things like that, we are seeing a little bit of a delay in some of the proof of concepts and things like that. So I think that's probably the bigger impact than over -- anything else at the moment. We just have to wait and see how it plays out. But certainly in the second half, we're anticipating that most of the kind of macro issues would have gone away. The coronavirus, hopefully, would be stabilized at least by that point, and I think we should be in good shape to see kind of a return to regular -- what we consider normal growth for our IoT business and LoRa business.

And then a couple of clarifications for Emeka. Emeka, regarding the new product impact to OpEx in the fiscal fourth quarter, was that mask set or was that something else? Can you just clarify what's going on there?

Yes, it mostly has to do with just the timing last year when we set at last start for take or share. Yes. So it had to do mostly with the mask sets.

Great. And then with regards to gross margin, I think you had indicated from the first quarter, you'd expect gross margin to rise through the year. Can you provide some further color, giving us a sense for the magnitude of the increase that's possible? And it seems like Signal Integrity should build quite strongly through the year. Is that really the primary variable? Or would it be the degree to which LoRa is either at the low end or the high end of the range or other factors?

Yes. So when we look at gross margins, and I'm actually excited about it because when I look at the growth drivers that we've talked about, we've talked about LoRa, we've talked about in data center, even within protection, we've talked about the industrial applications, hoping to see a lot of growth out of that for protection. So all of those are things that are supposed to help drive our gross margin expansion. The only thing that we have as a headwind for gross margin expansion, if you will, is the fact that overall demand is at lower levels, right? So we still have some manufacturing equipment and people in our operations with some fixed expenses that we have to absorb. So my expectation would be that a combination of more revenue from our growth drivers and then seeing overall demand coming back, that should be pretty good for our gross margins. As to the exact number at this point, I would probably expect us to head more towards the 62%, and hopefully, depending on how things proceed, we might actually exceed -- go above 62%.

Your next question comes from the line of Mitch Steves with RBC Capital Markets.

I had 2 questions. The first one, just to clarify, just on the guidance of the $10 million, I just want to be clear about what's in there. Is that entirely China? Or are you guys making an assumption that some demand will erode in the other geographies outside of China?

That's the total -- that's the global picture. So it's not just China. I would say that because China was the first to be exposed to the coronavirus, the impact is more easily measurable because they delayed New Year by a week and it's been -- it's taken time for their capacity to come back online. Whereas other regions haven't really been impacted yet, and I think that's still potentially to come. But I think across the board, what we've seen is $10 million is about the right number for our Q1 demand.

Okay. And then the second one is just on the overall kind of full year. I realize you guys are not going to guide a full year, but how do you -- how are you guys thinking about the smartphone shipment environment now for calendar year '20?

Yes, that's -- smartphones is a tough one, Mitch, and mostly because we're actually quite optimistic that the changing work landscape as people become more mobile and maybe do less social interaction, would drive a need for more devices, particularly phones and tablets and PCs and that type of stuff. So -- and currently, the demand looks fairly healthy from what we see. So yes, we're getting more positive, I think, not only device -- mobile devices, smartphones, but also on kind of other peripheral wearables and accessories and that type of thing.

Your next question comes from the line of Harsh Kumar with Piper Sandler.

2 questions. A couple of the companies that have sort of preannounced have talked about demand in China going back to sort of normal levels or pre-coronavirus levels. I was curious if you have also seen that. Then I've got another question on LoRa.

Yes, I would say, Harsh, that it's definitely improving. I'm not sure I would say it's back to pre-virus levels, but I think it's improving. Bookings are strong. The indications are strong. Indications of potential stimulus is also there for infrastructure. And as we know, typically when China invests in infrastructure, it's normally advanced technology kind of stuff. So we'd expect 5G and PON and data center and IoT and those type of things to get a heavy influx of monies. And so that would be helpful. But yes, I would say that it's improving. Remember, the coronavirus impact, China is just coming out of that. I mean at least get improving. And so they're not back at full capacity yet, and I think that's important to understand. So I don't think the demand levels are at quite what they were. I would say they're at best 70% to 80% at the moment.

Okay. And then, Mohan, thank you for all the color you gave on LoRa by funnel types, et cetera. Maybe you could talk about what kind of applications you are seeing a pickup in -- or expect to see a pickup in this year. Would it be mostly consumer? Or will it be mostly industrial? And is this the year -- calendar year, call it, 2020 that we see the U.S. inflection?

Yes. So the use cases, I think, are still more in metering, smart buildings, smart environment, smart water, industrial IoT kind of applications, Harsh, at the moment. But the pipeline of opportunities we have suggests that we're going to add to that very quickly in the smart home area, and I think that's predominantly a U.S.-driven segment, some in Europe and then I think supply chain logistics, smart logistics, which is predominantly a European-driven region. Europe is the major driver for that segment. And then smart city, which is fairly broadly spread. So the encouraging thing about LoRa really is it really truly is a geographical -- a true global technology. We see use cases across every single region, including likes of rest of Asia and Australia and Taiwan and Malaysia and Singapore. And so a very, very broad range of applications and a very broad geographical base. So -- and that's part of the goodness about the opportunity we have. Of course, there are some really big opportunities. That will be the catalyst. And as I mentioned before, when they happen, I think you'll see the impact of it. But at this point in time, I would just say that they are more U.S.-based.

Your next question comes from the line of Hamed Khorsand with BWS Financial.

This is Vahid for Hamed. First one, you were mentioning the LoRa growth out of China. I was wondering if you could provide some color on what the growth looks like outside of China right now.

LoRa growth outside of China is looking positive. I think it was -- I would say that it's relatively small, I mean, depending on which region you look at. But China is still the biggest revenue driver for LoRa. And so that's why I focused on it. But yes, across the board, I would say, LoRa, is still doing quite well from a gateways deployed standpoint, from a number of networks deployed, the type of use cases we're seeing. The opportunity pipeline, as I just mentioned, is very broad geographically spread. In fact, if I take out -- China is about 23% to 25%. If you take out China, the rest of the 75% is spread across the different regions, with Europe being the second largest region and then Americas and then rest of Asia.

Okay. And then the next question, you've been saying about how there's -- you're seeing the recovery in China. I'm just curious what trends you're seeing outside of China, Italy and America and Europe in general, the last few days.

Outside China, as I say, I think it's a little bit difficult to call what demands -- what's going to happen with demand. We don't see a slowdown in data center market at the moment. We don't see a slowdown in IoT. But I think that, in general, the U.S. and Europe are just kind of getting to grips with the coronavirus. And so we may see some softness there, I think. And that's kind of why we've guided -- taken out $10 million of our Q1 guidance is really to try to ensure we encompass any of that because there will be some. We don't know exactly how much, right?

Ladies and gentlemen, we have reached the end of the question-and-answer session. And I would like to turn the call back to management for closing remarks.

So in closing, our fiscal year 2020 proved a challenging year for Semtech. We believe the strength of the secular drivers behind our key growth engines remain intact. We enter fiscal year '21 with a number of exciting new product platforms targeted at the data center, Internet of Things and mobile segments. Given our diverse product offering, balanced end market approach and strong customer relationships, we expect to see another strong financial performance in FY '21. With that, we appreciate your continued support of Semtech and look forward to updating you all next quarter. Thank you.

This concludes today's conference. You may now disconnect. Thank you for your participation, and have a great day.
