Keh-Shew Lu
Thank you, Leanne. Welcome, everyone, and thank you for joining us today.
I am pleased to report that Diodes achieved record quarterly revenue despite the typical seasonal softness in the quarter and the slowdown at certain key OEMs. Our sequential revenue growth was due to the result of our continued design win momentum, as well as, one month of revenue contribution from our acquisition of BCD.
Additionally, non-GAAP gross profit margin, which excluded an inventory valuation adjustment related to the BCD purchases, improved 60 basis points sequentially and was favorable to our updated guidance due to revenue increases in the higher margin regions of North America and Europe, a better than expected manufacturing recovery following the Chinese New Year holiday, lower gold price and a more favorable product mix. Also during the quarter, we finalized our acquisition of BCD a much fit and the integration to-date has gone smoothly.
This transaction was immediately accretive to earnings, excluding purchase price accounting adjustment. We already have begun walking through so that the BCD product upload to our internal assembly test facility and that we’ll start the conversion to internal production in the first quarter this year.
We expect the conversion of maturity of the product that can be converted into internal production to be finished by the end of this quarter next year. We expect to begin benefit from the cross-selling synergies of expansion [and] offerings based in the fourth quarter of this year.
Overall, I'm pleased with the progress we made in the quarter in terms of design win momentum and the integration of our recent acquisition. As we do with the first quarter, set the stage for continued growth and the margin improvement in the second quarter.
With that, I will now turn the call over to Rick to discuss our first quarter financial results as well as second quarter guidance in more detail.
Rick White
Thanks, Dr. Lu, and good afternoon, everyone.
Revenue for the first quarter 2013 was $177 million, an increase of 8.4% over the $163.3 million in the fourth quarter 2012 and an increase of 22.3% from the $144.7 million in the first quarter 2012. The sequential increase in revenue was primarily due to one month of revenue contribution from BCD as well as the result of our continued design win momentum.
GAAP gross profit for the first quarter 2013 was $46.2 million, or 26.1% of revenue. As previously disclosed in our mid-quarter guidance press release on March 7, our guidance did not include the impact of any BCD purchase price accounting adjustments.
Based on our subsequent initial evaluation of BCD’s acquired assets, GAAP gross profit for the first quarter 2013 included an inventory valuation adjustment related to the BCD purchase totaling $1.8 million. Excluding this amount, non-GAAP adjusted gross profit was $48 million, or 27.1% of revenue, compared to GAAP gross profit of $43.2 million, or 26.5%, in the fourth quarter 2012 and $33.7 million, or 23.3% of revenue, in the first quarter 2012.
The 60 basis point sequential improvement and the favorable upside versus our updated guidance in gross profit margin was due mainly to increased revenue in higher margin regions, a better than expected manufacturing recovery following the Chinese New Year holiday, lower gold prices and a more favorable product mix. GAAP operating expenses for the first quarter were $42.4 million, or 24% of revenue, which included approximately $900,000 of items related to the BCD acquisition and $1.9 million related to amortization of acquisition intangibles, compared to $39.7 million, or 24.3% of revenue in the fourth quarter 2012 and $28.2 million, or 19.5% of revenue, in the first quarter 2012.
Excluding acquisition-related costs, amortization of acquisition intangibles and the gain on the sale of an asset, operating expenses on a non-GAAP basis for the first quarter 2013 were $39.6 million or 22.4% of revenue, compared to $36.5 million or 22.3% of revenue in the fourth quarter 2012, and $29.2 million or 20.2% of revenue in the first quarter 2012. Looking specifically at selling, general, and administrative expenses for the first quarter, GAAP SG&A was approximately $30.4 million or 17.2% of revenue compared to $28.7 million or 17.6% of revenue in the fourth quarter 2012, and $22.1 million or 15.3% of revenue in first quarter 2012.
Non-GAAP SG&A was $29.5 million or 16.7% of revenue compared to $27.2 million or 16.6% of revenue in the fourth quarter and $22.1 million or 15.3% of revenue in the first quarter 2012. Investment in research and development for the first quarter, on a GAAP and non-GAAP basis was approximately $10.1 million or 5.7% of revenue, compared to $9.3 million or 5.7% of revenue in the fourth quarter 2012 and $7.2 million or 5% of revenue in the prior year quarter.
The increase in R&D reflects our additions to BCD. Total other income amounted to $500,000 for the first quarter.
Looking at interest income and expense, we had approximately $850,000 of net interest expense, which was more than offset by currency gains mainly in Europe. Income before taxes and non-controlling interest in the first quarter was $4.3 million on a GAAP basis and $9 million on a non-GAAP basis, which excludes the above-mentioned acquisition adjustment and other items.
This compares to income of $6.6 million in the fourth quarter 2012 and $6.2 million in the first quarter 2012. Turning to income taxes, GAAP income tax expense was $6.6 million and included a $5.4 million China tax audit adjustment with a 2011 tax year.
As previously disclosed, the China government audited the high-tech company status of our largest China subsidiary for 2009, 2010, and 2011, which had utilized a preferential tax rate of 15%. On April 11th, we were notified by the China government that they had completed their tax audit and concluded that we owed additional tax related to the 2011 tax year in the amount of $5.4 million.
GAAP net loss for the first quarter was $1.9 million, or $0.04 per share, compared to GAAP net income of $4.1 million or $0.09 per diluted share in the fourth quarter 2012, and GAAP net income of $4.9 million or $0.10 per diluted share in the prior year quarter. The share count used to compute GAAP earnings per share, EPS, for the first quarter was 46 million shares.
First quarter non-GAAP adjusted net income was $7.5 million, or $0.16 per diluted share, which excluded net of tax $2.5 million of items related to the BCD acquisition, $1.5 million of non-cash acquisition-related intangible asset amortization costs and $5.4 million related to the China tax audit adjustment. The fully diluted share count used to compute non-GAAP earnings per share for the first quarter was 47.2 million shares.
We had included, in our earnings release, a reconciliation of GAAP net loss to non-GAAP adjusted net income, which provides additional details. Included in the first quarter GAAP and non-GAAP adjusted net income was approximately $2.1 million net of tax of non-cash share-based compensation expense.
Excluding share-based compensation expense, the GAAP net loss of $0.04 per share would have improved by $0.05 per share, and non-GAAP adjusted net income of $0.16 per diluted share would have improved by $0.04 per diluted share. Cash flow generated from operations was $31 million, and free cash flow was $15 million for the first quarter.
Net cash flow was a positive $43 million for the first quarter, including approximately $20 million of BCD’s cash at the end of the quarter. Turning to the balance sheet.
At the end of the first quarter, we had approximately $200 million in cash and cash equivalents. Working capital was approximately $453 million.
At the end of the first quarter, inventory was approximately $182 million including $40 million of BCD inventory. Excluding BCD, our inventory of $142 million was down approximately $12 million from the fourth quarter 2012, mainly due to a decrease in finished goods.
Inventory days were 115. Excluding BCD, days decreased to 112 in the first quarter compared to 119 days in the last quarter.
At the end of the first quarter, accounts receivable was approximately $172 million and AR days were 82 compared to 87 last quarter. Capital expenditures for the first quarter were $13.2 million, which included $5.6 million related to the expansion of our Shanghai Sales and Design Center.
Excluding this amount, capital expenditures were 4.3% of first quarter revenue compared to 5.6% in the fourth quarter. We expect capital expenditures to range between 5% and 9% of revenue for 2013.
Depreciation and amortization expense for the first quarter was $17.6 million. Now turning to our outlook, for the second quarter of 2013, we expect continued growth with revenue increasing to between $206 million and $218 million, or up 16% to 23% sequentially, including the first full quarter of revenue from BCD.
GAAP gross profit margin, which will include approximately $4 million related to an inventory evaluation adjustment pertaining to inventory acquired as part of the BCD purchase, is expected to be 27%, plus or minus 2%. Non-GAAP gross profit margin, excluding the inventory evaluation adjustment is expected to be 29% plus or minus 2%.
In early second quarter 2013, we announced a restructuring of our U.K. development team and the closure of our New York sales office.
We expect that these actions will be completed in second quarter. Restructuring costs included in the second quarter 2013 are expected to be approximately $1.7 million and will provide savings going forward of approximately $3 million per year.
GAAP operating expenses are expected to be 23.6% of revenue, plus or minus 1%. Non-GAAP operating expenses, excluding amortization of intangible expenses, restructuring expenses, and BCD retention bonus accruals are expected to be 21.3% of revenue plus or minus 1%.
We expect our income tax rate to range between 14% and 20% and shares used to calculate GAAP earnings per share for the second quarter are anticipated to be approximately 47.4 million. For more detail on the outlook, please see our press release.
With that said, I will now turn the call over to Mark King.
Mark King
Thank you, Rick, and good afternoon. Our achievement of 8.4% sequential growth and the record quarterly revenue was driven by strong increases in North America and Europe, which recovered from a very weak 3Q and 4Q as well as one-month revenue from BCD.
The industrial and communications sectors included in both of these regions, while computing was slightly better than expected with expansion in Wi-Fi modules. Although, the consumer market was softer, we continue to execute our strategy and capitalize on our strong position in smartphones and tablets with new products and design wins in both devices and chargers.
OEM sales for the quarter were down 8%, and distributor POS was up 8%. It was a strong quarter for PLP, as distributors began anticipating market improvement and started building required inventory, especially in North America and Europe where inventory had been reduced to minimum levels.
Distributor inventory rose 4% after two consecutive quarters of decline. Global inventory remained in line and under three months.
Turning to global sales, Asia represented 79% of revenue, North America 11% and Europe 10%. Our end market breakup consisted of consumer representing 31% of revenue, computing 29%, industrial 19%, communications 17% and automotive 4%.
With the completion of our recent acquisitions and differences in market sector reporting, we plan to redo and align our market sector definitions in the second quarter. In terms of new product and design wins, we had a strong quarter with another revenue record on CMOS LDOs, along with positive momentum in DC-to-DC converters, LED backlighting, audio, hall sensors and SBRs for the broad-based market.
Design wins also remained strong, and we have a solid pipeline of designs going forward. Starting with discrete, product introductions totaled 25 new products across 10 product families, representing a wide range of application segments and markets.
There were several important new products introduced for the high-volume portable market space. These were complemented by products targeting at computing, consumer and industrial applications worldwide.
Of particular note is the device launched using Diodes’ proprietary SBR technology, which demonstrates leading-class performance in thermally-demanding small form factor portable adapter application. This product was designed, prototyped and ramped for full volume production in one quarter for leading Asian manufacture of mass market portable devices.
This rapid product ramp is a good example of Diodes' superior application know-how, design agility, and manufacturing flexibility. We expect further developments in this technology area in the coming quarters.
Also targeted the portable market space, Diodes further expanded its range of miniature DFN package devices, with addition to the thermally and space efficient DFN 10-006 package. These new devices comprise a range of MOSFET, Schottky and [QBS] products developed specifically to meet the needs of several of the world's leading portable device manufacturers.
Also during this quarter, we introduced the first two devices in a range of regulated transistors created for telecom, networking, and power over Ethernet application. These devices minimize footprints by reducing component count and increasing power density, which are two of Diodes' core strengths.
Turning to analog new product introductions, which now include product released by BCD, we introduced 115 new products across six product families. New product highlights include the release of several new [positive] side regulators and a primary side dynamic accelerator, targeted for portable chargers and power adapters.
The AC/DC power area is an exciting new product space that the acquisition of BCD has opened for Diodes. During the quarter, we secured 18 significant new AC/DC wins for mobile charger applications.
Also during the quarter, we added several new DC-to-DC buck converters including several synchronous high-speed preempt devices intended to support portable consumer equipment powered from lithium ion battery. We racked up several design wins for set-top box, modem, and flat panel TV with our family of recently released 2-amp and 3-amp light load, high efficiency buck converters.
With the addition of the low-voltage converters, boost converters and DC-to-DC controllers, from our recent PAM and BCD acquisitions, Diodes now offers a broad and effective DC-to-DC product portfolio. This includes a family of low-voltage converters with a strong position on several major Wi-Fi module reference designs.
We also expanded our line of LED backlighting drivers with the addition of product families from PAM and BCD. Our newest linear LED driver provides a simple cost effective solution for low current LED lamps that are ideally suited for monitors and flat panel TVs.
In addition to backlighting, we could hear wins in the off-line space with several dimmer and retrofit bulbs applications as well as general illumination wins in automotive and industrial space for M16 retrofit bulbs. Turning to our home sensor portfolio, we released a line of sensitivity selectable micro power hall switches that are offered in miniature low profile CSP packages.
These devices are designed specifically for battery-powered consumer applications such as cellphones and tablet PC. Sensor design wins during the quarter included several DC fan motor sockets, open, close position sensors for notebook computers, and medical physician encoder sockets and an energy metering application.
During the quarter we announced the expansion of our standard logic product line with more package options added to our four families of high-speed and advanced high-speed CMOS parts. These new devices are widely used in computing, consumer electronics, domestic appliances, building controls and industrial automation applications.
Additionally, the new logic families cover a wide voltage range from 2 volts to 5.5 volts, which means they will support legacy applications and can be tailored for low-voltage and low-power applications as well. In summary, the first quarter represented significant progress in advancements for Diodes.
We completed our acquisition of BCD to complement our recent acquisition of TAM. These acquisitions significantly increased Diodes’ presence in the analog market with expanded product portfolios and have also expanded our sales and customer footprint.
Coupling them with Diodes’ new product and design win momentum positions us well for long-term profitable growth. With that, I’ll open the floor for questions.

(Operator Instructions) Your first question comes from the line of Steve Smigie from Raymond James. Please proceed.
Steve Smigie - Raymond James
Great. Thank you very much, and I want to say congratulations on the great report and guide here to impressive margin improvement there.
Dr. Lu, I was hoping you could talk a little bit now about BCD, as you’ve had it in-house for little while.
Have you had any customer response on potential cross-selling opportunities? Does it seem like that’s going to be some decent revenue leverage there?
Keh-Shew Lu
Yeah. Thank you, Steve.
Yes. I think, number one, the consolidation is pretty good.
Everything is smoothly doing and we still have further work to be done, but till today everything is doing well. Second, yes, we get a pretty good feedback from customers especially with BCD product compliment with Diodes' product.
We provide much bigger scale of the product portfolio to our customer and this kind of one-stop shopping is really help our customer and people -- our customer really feel very good. So the feedback from our customer about the synergy, you know, the sales synergy, I'm still very happy.
And I think in the speech, we are talking about, we think we can start to have a cross-sell synergy realized in 4Q this year because it takes time to get customer design win and go to production.
Steve Smigie - Raymond James
Great. Thanks.
And on the margin side, can you talk a little bit about how you are thinking about gross margin? You know you have BCD and I think the margins at the end of the day weren't that different.
So, I'm going to guess, we should see probably if revenue keeps creeping up here, that we would see some margin leverage, so, I guess, the question is, will you keep seeing continued margin leverage? And just to sneak one last one, can you give some guidance or thoughts on how the tax rate looks going forward?
You know sort of post June it seems a little higher than you used to have. Thanks.
Keh-Shew Lu
Okay. I probably cannot give you the particular specific number because we are not really [reduce it] – and other than second quarter number, okay.
But, need that you realize, in the 1Q, in BCD, we have to adjust that to ramp it up in January, okay, so we still in the ramp up mode in the second quarter. And that under-loaded ramp-up is going to be negative impact to our GPM percent.
But moving forward I think we are – we already started working on offloading or co-define BCD product into Diodes' SKE assembly and I think we say in our speech, the offload will be started in 4Q this year, and majority of what we want to move will be probably completed by end of 1Q next year. And therefore, this will be, for sure, improve our GPM percent, okay, in the future.
At the same time, we are looking at move our Diodes' analog wafer loading into the BCD and we already identify where we can move our wafer into the BCD, but, of course, its takes time to qualify. The process is almost – is already there.
We just need to qualify it and do the PCM, and the customer expect that will go through a change, and then we will be start to able to offload our analog wafer into the BCD fab. So, again, it won’t be immediately impacted in 2Q, 3Q but farther down the line.
It will depend on when the customer acceptance and we [didn’t] as convert, I think, in the future, it will be greatly impact our GPM percent improvement.
Steve Smigie - Raymond James
Okay. And, Rick, any thoughts.
So is the tax that you guys provided for June – is that sort of more what we should be thinking as the rate going forward or is that sort of a one-time rate above normal?
Rick White
No, no. That tax rate where we said 14% to 20% is going forward, not just the second quarter rate.
It’d be for the rest of the year.
Steve Smigie - Raymond James
Okay. Great.
All right. Congratulations, again.
Thank you.
Keh-Shew Lu
Thank you.
Operator
Your next question comes from the line of Christopher Longiaru from Sidoti & Company. Please proceed.
Chris Longiaru - Sidoti & Co.
Hey, guys. I’ll add my congratulations.
Great quarter. Great guide.
Keh-Shew Lu
Okay. Thank you, Chris.
Chris Longiaru - Sidoti & Co.
My first question is for Mark, because I was just a little bit confused. Essentially, you said that consumer was weak but that basically the cell phone guys like HTC, Samsung made up for some of that weakness.
Is that what I am to understand?
Mark King
I think that would be a good assumption.
Chris Longiaru - Sidoti & Co.
Okay. And then just in terms of the expenses going forward, so you have some restructuring charges on a GAAP basis.
Do those go away, as we move on past June? And then, when you talk about the restructuring saving about $3 million in annual costs, will we start to see that in the September quarter?
Keh-Shew Lu
Well, the answer is yes. Okay.
The destruction is happening now. Okay.
Rick White
Restructure.
Keh-Shew Lu
The restructure is happening now. So in the coming quarter you will benefit that $3 million a year.
You will benefit from now on.
Chris Longiaru - Sidoti & Co.
Okay, got it. And just from a gross margin perspective, BCD was at about 22%, for gross margin, when they were on their own.
So it looks like the incorporation of that month might have actually hurt your gross margin in the short-term because you haven’t had a chance to bring that in-house. Is that accurate?
Keh-Shew Lu
Well, I cannot comment a percent, but like I said, yes, it will be hurting us in the average. But, you know, from long-term it’s going to be helping us and I cannot comment on the number.
Okay. But, yes, it’s because they are under-loaded and the ramp-up on Fab 2 and Fab 2 is there last year, it started ramping up in January and it takes time to ramp up.
Chris Longiaru - Sidoti & Co.
That's helpful. I think that's all I have for now.
Thanks guys.
Keh-Shew Lu
Thank you, Chris.
Operator
Your next question comes from the line of Gary Mobley from Benchmark. Please proceed.
Gary Mobley - Benchmark
Hi, guys. Thanks for taking my question.
Keh-Shew Lu
Hi, Gary.
Gary Mobley - Benchmark
I wanted to hone in on the gross margin, if you look at the midpoint of your gross margin guide for the June quarter, it’s about a 300 basis point sequential improvement. How much of that is a function of better fixed cost coverage, better depreciation, expense coverage, and how much is attributable to, you know, you picking and choosing which opportunities to chase, in other words, selling only the highest margin products, and how much it has to do with the continual conversion to gold bond wiring?
Thank you.
Keh-Shew Lu
Okay, great. We really don't separate all this one, okay, because they give me no forecast, I can solve that, and then we do indeed.
So it's very difficult for me to say how much is due to what, what, what. But what you uncovered is all true.
Number one, I’ve been talking about gold price and you know the gold price going down in 1Q, and it continue going down. From average point of view, we are really making some assumptions for 2Q and obviously 2Q going to be cheaper than the average of the 3Q – of the first quarter.
So gold price is helping us. Second, output more because the business going up, and you can see the growth, and that -- so because 1Q is slow quarter for us, and because the second quarter growth the (inaudible), it will be improve the – profitability of our make and function due to best unloading factors.
Number three, product mix, and the picture has started getting better. We are moving our mix to the better for us and so that is the result.
And the price stability, I think, we already see price stabilize. I'm not saying increase, although, some misunderstanding.
When I say stabilize is, we expect, I think, in the past, certain percent of the price drop every quarter. And as long as it’s within that kind of price curve, our productivity improvement should take care of that, and then it’ll give us a better GPM percent.
So I think whatever you have been seeing, talking about the problem affect us, those are four factors. Now, it’s turned into good for us.
So that’s what happened.
Gary Mobley - Benchmark
Okay. I was just hoping to get a couple follow-up ratios as well and the percentages.
Looking forward, what is the split between analog and discrete? And looking into your June quarter guidance -- correct me if I’m wrong, but is that assuming about 5% organic growth?
And then, last, Mark, if you can share with us the book to bill ratio for the quarter and that’s it for me.
Keh-Shew Lu
Well, Gary, we really -- since we don’t separate analog from the discrete, I cannot really be talking about how many percent. And from a growth point of view, again, since we don’t separate BCD from Diodes.
So I cannot tell you. But one thing you just need to guess from yourself.
BCD gave the guidance on what 1Q -- what would be in the 1Q. That is the public information.
You take that, you assume some percent, then you can -- from there, you can figure out on your own. But since we do not disclose any separation between analog business to discrete, we don’t separate from BCD from Diodes, I cannot disclose that.
Rick White
On the book to bill, we don’t really get into the real details of that, but I would say it's obviously above, one, based on the guidance and we're pretty well positioned for the second quarter.
Gary Mobley - Benchmark
Thank you.
Operator
Your next question comes from the line of Shawn Harrison from Longbow Research. Please proceed.
Shawn Harrison - Longbow Research
Hi. Good afternoon, everyone.
Keh-Shew Lu
Yes. Hi, Shawn.
Shawn Harrison - Longbow Research
I wanted to get back to the comments about distribution in terms of point of sale increasing and inventory rebuilding. Where do you think you are, I guess, in terms of distributors adding inventory?
Will you see them build more inventory this quarter? And, I guess, how long can we see that go on for?
Rick White
I don't know, I think that, again, it was a pretty strong quarter, but we had actually -- our inventory had gone down to amazingly low levels, so our inventory in the channel in North America and Europe was very, very clean, and solidly positioned in Asia. So I think that – but we were also very happy with the few escrows that in quarter.
There was a big recovery in both North America and Europe in POS in the third and fourth -- from the third and fourth quarter, so we think it's good. I just came back from EDS show and everybody is cautiously optimistic going forward about where this is going.
Nobody really wants to commit. But I think that the clear indication is, is that, they feel comfortable investing as they see opportunities to do so.
So I think we'll continue to see opportunities to position product for future POS growth.
Shawn Harrison - Longbow Research
Mark, are you seeing, I guess, lead times expand for your products? And I guess that could be a driver for distribution for your inventory.
Mark King
We're seeing a little bit of words about lead time extensions on some of the lowest level commodity products. I think a couple of guys are trying to firm up their backlog a little bit, but I don't think anything excessive.
Shawn Harrison - Longbow Research
Okay. And then, Rick…
Keh-Shew Lu
Not really. No, we are running -- our business is not really using lead time on this, right.
We used it -- I think I’ve been telling -- talk about our business model is put a wafer in front of assembly, and so our assembly lead time is not high, and therefore, our customer know, they just order when they need it, when they’re across, they need it. They don't give us double order or that kind of thing.
So I think our business model really to take care of that kind of long lead time, and ordering and double booking that kind of situation.
Shawn Harrison - Longbow Research
Got you. And then, two brief follow-ups.
Rick, maybe if can give us the expected interest expense for the June quarter. And then, also just in terms of -- with the better trends you're seeing in the business organically right now, what does that mean for the packaging facility in Chengdu?
Rick White
Okay. So, the interest expense for the second quarter is just going to be, basically, the first quarter plus a little bit more.
I don't have that exact number here. We borrowed the money to buy BCD in January and February area, so it's going to be maybe a little bit more than what we had in our results.
And tell me again, what was the other one about Chengdu?
Shawn Harrison - Longbow Research
Just in terms of the organic environment being better. What does that mean in terms of just CapEx with the facility and maybe bringing online quicker, anything of that nature.
Keh-Shew Lu
Yeah. From Chengdu we still not putting the expansion aggressively yet okay, because we still have unresolved situation in our Shanghai facility.
But we are watching very closely, because you need certain lead-time for the build-up of the factory. So we are now looking at what we need to do in Chengdu and the timing.
Okay. But here today, we’re still keeping us a power line, we run in it, keep people under the training get ready.
The building construction is already done, and whenever we are ready, we will start to put in the clean room and start to get -- move the equipment from our power line to the manufacturing site. Okay.
Shawn Harrison - Longbow Research
Very helpful and congratulations, again, on closing the acquisition.
Rick White
The one other comment about interest expense. If you look at our interest expense in the first quarter, it was about a little less than $1 million.
And so because we’re going to have a full quarter of interest expense, it’s going to be somewhere over $1 million probably, $1 million to $1.5 million would be my guess.
Shawn Harrison - Longbow Research
Okay. Thanks so much, Rick.
Keh-Shew Lu
Yeah. And another thing I would probably want to mention, you know, you can – you probably started to realize, when we talking about capital expenditure as a percent of revenue, we are no longer talking about [skewing] the Chengdu.
It just means, from now on, our capital expenditure in the Chengdu will be going to be part of the model. Okay.
So if you look at, when we look at capital as a percent of revenue in our model, Chengdu will be part of that now. Okay.
So we are no longer treating Chengdu separately.

Your next question comes from the line of Harsh Kumar from Stephens. Please proceed.
Harsh Kumar - Stephens
Yes. Hey, Dr.
Lu, congratulations on great guidance, good gross margin increases. I wanted to follow up on a couple of questions.
First of all, maybe for Rick, Rick, why are the taxes going to be 17 versus historical? Like what's the big reasons, why they will stay up like this?
Rick White
Well, if you go back historically, our tax rate has been anywhere between 15% to 20%. So over the last year or so, we've been at less than 15, a couple of times, and the reason is that we've had some losses in certain areas, and that affects your tax rate.
So, as moving forward, things seem to be improving.
Keh-Shew Lu
GPM is improving.
Rick White
Yes. GPM is improving.
We went from 23% in the first quarter of last year to the 26% now. So things are improving, plus as Mark mentioned, the revenue in Europe and the U.S.
is holding up pretty well, which is where you have high profitability but you also have higher taxes there.
Harsh Kumar - Stephens
Fair enough. Just wanted to clarify that and then -- and Dr.
Lu, you gave a bunch of reasons for margin increases. And you didn't want to get into the numbers, but I was curious, Dr.
Lu, if you could just say what's the biggest reason that's driving margins in the June quarter and even beyond, if you had to pick one out of the four or five you listed.
Keh-Shew Lu
Well, obviously due to the ionization and our productivity improvement in the [making] going to be big this year. Go up and down, okay, Yeah, that's one of the reasons, but I won't just say that is really the major one.
Okay. Product pricing, I say, stable, but it's not going to be up.
So it's not going to help. It just stopped going down.
Right. And yeah, and so, the key thing really is when the business started going up, your loading started to improve and you can realize we are not putting that much of capital anymore, because if you go through the last quarter, and the fourth quarter last year, we have been -- distract our capital investment, and that means our capacity is not going to be increased that much, and that means our ionization of the capacity going to be improved.
So you ask me, I want to tell you the truth, it's not -- I'm not telling you the truth, I’ll just say, to be still asking, what was the biggest factor. I would say productivity improvement on our making function plus the ionization of our capacity is the key factor.
And then I think the ionization has been hurting us in the past. And we are waiting for business trend and we can start to ionize that capacity.
Harsh Kumar - Stephens
Fair enough. Very helpful, Doctor, Lu.
And then you talked about backend integration of BCD sort of manufacturing and you said you started that. Has a lot of that been done, or are you just kind of started it, and it will take a few more quarters?
Keh-Shew Lu
Okay. When we say it's started, is we already said that the product we want to convert internally, offload internally, start to do the qualification.
And you know, the core, it takes three months. Okay.
Then, after you core, then you need to do a PCM to notify the customer. It takes another three months.
Then, for the small customer, they might allow you to convert it immediately. And that’s why I would say, 4Q, we’ll start it.
But some of the major customers, they just want more time to convert. And so I said, by end of 1Q next year, majority of what we want to convert will be converted.
Harsh Kumar - Stephens
Great. That’s very helpful.
And then, Dr. Lu, at this time, a couple of years ago, you had a China labor problem where you didn’t have enough workers coming back.
Anything noteworthy this time around or is everything going on plan?
Keh-Shew Lu
It’s all the same way. The China labor shortage -- China labor don’t come back.
I’m not seeing a major improvement. No.
But since this is not the first time – this is, I think, third or fourth time we see the problem – we already know how to handle. The first time, you say, two or three years ago, it feels as a surprise.
And now we know how to handle it. So we prepare for it.
I think, if you remember, last conference call, we said we’ll build some inventory in by end of fourth quarter to prepare for Chinese New Year shutdown. And then we know how to stage our people instead of all going on the same time on the Chinese New Year.
So we’ve already done how to handle and we can handle it each year better and smoother. That's why this time we said, better than we expected.
It's just more experience handling this. And we prepare for it.
We view the inventory in fourth quarter.
Harsh Kumar - Stephens
Fair enough, Dr. Lu.
Congratulations again. Thanks.
Keh-Shew Lu
Thank you.

Your next question comes from the line of Vijay Rakesh from Sterne Agee. Please proceed.
Vijay Rakesh - Sterne Agee
Hey, guys. Dr.
Lu, congratulations. Good gross margins finally.
Keh-Shew Lu
Hey, thank you.
Vijay Rakesh - Sterne Agee
I had a couple of questions. So just looking at the OpEx side from BCD, do you think there are any levers that I should go through for second half this year, first half next year?
Keh-Shew Lu
Number one, we are not doing any day off or anything. We want to keep everybody from BCD team because we believe their people is good people, is really good, and that's the reason we bought BCD.
So now, we are not going to reduce the headcount. But if you do look at, if we can continue grow the revenue, then as a percentage, it will go down, and that's the way Diodes has been doing in the past, is we keep everybody -- we kept everybody, and we aggressively grow the revenue and bring the GPM percent, go back to our business model.
And we did that when we have -- we did that in the past, is we have a bit of model, our IMD plus SG&A 20% of revenue. We’ll suffer at the beginning, slightly higher, then we said, we – when the revenue start to grow the number will go down.
And we proved that into that position, and now we're going to prove the same thing. We are doing the same way for the BCD acquisition.
Vijay Rakesh - Sterne Agee
All right. And as you look at the June quarter, your BCD was a little bit of a drag with underutilization.
Do you think you will get little bit more tailwinds for the margin line with as all those underutilization charges go away in the back half at BCD?
Keh-Shew Lu
Well, I think, actually BCD going to be have more loading in second quarter than first quarter. Because first quarter from January is zero, it start to ramp.
And so…
Vijay Rakesh - Sterne Agee
Yeah.
Keh-Shew Lu
…1Q, if you take the average, that we only confirm much, but even though much, just third month into the ramp, fourth quarter…
Vijay Rakesh - Sterne Agee
Yeah.
Keh-Shew Lu
…fourth quarter – second quarter, they contribute rent more and they will contribute more from the GPM percent, okay. But don't forget Diodes is improving, too, and so it may still negative impact us.
But it's no longer are very significant. The move forward, when the loading start getting better, and that both, fab one and fab two, then when we start to produce a product for them, they of course go down, and at the end, they are going to be helping or we should say, the total together, should we help each other.
Vijay Rakesh - Sterne Agee
Got it. And last question, on the tax rate, it creeped up a little bit.
I know you said some revenues from high margin, high tax rate regions, I guess. It looks like you still decent revenues coming from Asia still right.
As you look at next year, do you still think tax rate stays at this level, it goes down or is it too far out to say?
Rick White
Oh, I think it’s too far out to say. It really depends on where the revenue is generated and where the profit is generated.
The big difference is between U.S. tax rates and the preferential tax rates in China, for instance.
Sorry.
Keh-Shew Lu
And Taiwan.
Rick White
And Taiwan too, yeah. Correct.
So it’s too far out to say.
Vijay Rakesh - Sterne Agee
Okay. Great.
Thanks a lot.

Your next question comes from the line of Lena Zhang from Blaylock Robert Van. Please proceed.
Lena Zhang - Blaylock Robert Van
Hi. Thank you for taking my questions, and add my congratulations as well.
Keh-Shew Lu
Thank you.
Lena Zhang - Blaylock Robert Van
And I understand that you guys don’t quantify the gross margin drivers for Q2, but if you -- given a pretty bigger delta for Q1 results and guidance, if you could quantify the gross margin expansion drivers, that would be very helpful for the modelling.
Keh-Shew Lu
Well, Rick.
Rick White
So the question is between the guidance and the results for the first quarter?
Lena Zhang - Blaylock Robert Van
Yeah. If could you quantify the gross margin expansion drivers for Q1, that would be helpful.
Rick White
So I think Dr. Lu went through that.
And we think a lot of that will have to do with productivity and utilization of our SAT assembly facilities, as the volumes increase.
Keh-Shew Lu
Yeah. I think…
Lena Zhang - Blaylock Robert Van
Okay.
Keh-Shew Lu
…in our speech, we already say, okay – in our speech, is productivity improvement is better than expected Chinese New Year recovery. I think that -- we put in the model of how the Chinese New Year going to be recover, based on our past experience, and you know, the past is always -- when you go through the Chinese New Year, and allow the people go home and don't come back, or come back late, and that reduce the output.
And when you output reduced and now making function is equal to capacity, empty fixed cost is there, capacity is not fully utilized then your profitability can reduce. Okay, as I say in my speech, I said several things.
One is the better than expected sales in the North America and the Europe, the high GPM area, but the key one we can say is Chinese New Year recovery, better than I expected, and some gold price. Gold price in the 1Q actually lower than 4Q or lower than expected and the mix is better, but you go back to the whole thing, the big one is still manufacturing.
Manufacturing, productivity, because that's really is my nightmare, I think in the last several quarters, or probably last year, the whole year, I am saying, roughly we are not utilized, you know, we are not fully utilized. Our capacity utilization is bad and 1Q is actually -- is not as good because of the Chinese New Year holidays.
Lena Zhang - Blaylock Robert Van
Okay, thank you. And also, what was the utilization rates for Q1 and what's your expectation for Q2?
Keh-Shew Lu
I don't think we give that number. We don't give that kind of number, okay.
Lena Zhang - Blaylock Robert Van
Okay. Thank you.
That's all I have.
Keh-Shew Lu
Okay. Thank you.

(Operator instructions) Your next question comes from the line of Stephen Chin from UBS. Please proceed.
Stephen Chin – UBS
Hi, Dr. Lu.
Thanks for taking the questions. And let me also add my congratulations on the acquisition and solid results.
Keh-Shew Lu
Yeah. Thank you, Steve.
Stephen Chin - UBS
Yeah, I have a few questions on the BCD kind of wafer fab to kick things off and then a couple on demand side of things. With BCD's analog side, can you talk a little bit about some of the -- I guess, costs or maybe technology advantages that might give you guys – especial, as you talked about converting some of your existing analog products from outside analog with foundries to the BCD internal process?
Can you talk about the technology and the cost benefits of that?
Keh-Shew Lu
Okay. Number one, BCD, obviously, [located] in China, and it's well rounded by BCD.
They are fab one is the cost I would say I would say, I'm very happy with their cost. Okay.
So, most our analog wafer is six-inch, so BCD says six-inch. Therefore, they don't have any penalty of the six-inch, but by [located] in China with the BCD technology, they do have a very good BCD process, and that is going to help.
So, from technology point of view, they provide me to move our analog product from our outside foundry to go into our internal fab with very efficient, very cost-effective fab. I’m happy with that.
And they do have the technology for us to utilize the capacity.
Stephen Chin – UBS
Okay.
Keh-Shew Lu
Equal opportunity and another thing to create opportunity they are under-loaded. Okay.
So if we can start to move our stuff over there, it helps both. Their cost will be even better because they are under-loaded, and we can get it cheaper because they are very cost-effective.
Rick White
Yeah. Steve, one of our biggest part of our models is manufacturing margin.
Okay. So they give us a lot of same leverages that we had with our internal assembly from a wafer perspective.
There is no foundry profit in there. So the foundries we do business with have to make a profit.
Stephen Chin - UBS
Got it, and that’s helpful. And then just one other thing really to that fab, I think, before the deal closed, I think, you previously communicated that the revenue capability of that new capacity was somewhere, I think, in the $75 million range, if I remember that correctly.
And I think they also had some targets or timeframe for when they think that revenue level could be achievable. Is that still the case?
And if so, as you – was there any expected business that was in the pipeline for filling the fab, and if not, can all of the current analog business that Diodes have, the existing organic analog business that you guys have, can that fill the majority of that?
Keh-Shew Lu
Okay, Steve, I really don't know what is their previous announcement. Whatever you’re quoting, I really don't know, because I don't pay that much attention to the past, okay.
All I know is the fab 1 today is under-loaded, important for me is loading to help to get Fab 1 loaded. Number two, they are moving their Fab 1 loading to their Fab 2 because Fab 2 two started, and they really need to get Fab 2 ramping up and get loaded, okay, especially Fab 2 have a better equipment, better process, and they can support a customer better.
So, basically, you know, what we really do is move some of the BCD high-end product into the Fab 2, to help the Fab 2 loading, at the same time, we are moving Diodes product which can be loaded in Fab 1. We are loading to Fab 1, and this is going to be -- each benefit.
Now, if Fab 1, A, current equipment fully loaded, then I'm ready to put another step of the equipment to make it up Fab 2a fully loaded. So Fab 2a currently still don't have all the equipment to be fully utilized that space.
Okay. And if -- but they don't need it now.
But when fab 2A started loading up for you then we'll put the capital improvement to get 2A fully loaded. Then later on, if the business is still going up, if we still need the capacity, then we expect to be, we can open it up and put the capacity in there.
So it's just straight, step by step and look at the loading, look at the requirement and really look at how the business progress.
Stephen Chin – UBS
Okay. Got it.
That’s very helpful. I think you’ve gave additional color.
And then just last question probably for Mark on the demand side, just wanted to see if most of the distributor related demand that you’re seeing, is that fairly restocking or do you actually have some sense on or some commentary on actual growth in demand that the distributors are seeing?
Mark King
I think we saw growth in both. Actually, the POP grew, say in North American and Europe faster than the POS.
But the growth rates on POS were very positive and they’re coming off very, very soft POP quarters the last two quarters. So it's required -- the inventory level got to a point where it really required them to invest greater than POP.
It should level pretty good, but the growth rate in POS was quite impressive in Q1 versus Q4 and even Q1 over Q3.
Stephen Chin – UBS
Okay, perfect. Thanks so much.

Yeah.
