Good day, ladies and gentlemen, and welcome to the PDF Solutions, Inc. Conference Call to discuss its financial results for the third fiscal quarter ending Tuesday, September 30, 2015. At this time, all participants are in a listen-only mode. Later, we will conduct a question-and-answer session for which instructions will be given at that time.

[Operator instructions] As a reminder, this conference is being recorded. If you have not yet received a copy of the corresponding press release, it has been posted to the PDF's Web-site at www.pdf.com.

Some of the statements that will be made in the course of this conference are forward-looking, including statements regarding PDF's future financial results and performance, growth rates, and demand for its solutions. PDF's actual results could differ materially.

You should refer to the section entitled Risk Factors on pages 12 through 18 of PDF's Annual Report on Form 10-K for the fiscal year ending December 30, 2014 and similar disclosures in subsequent SEC filings. The forward-looking statements and risks stated in this conference call are based on information available to PDF today.

PDF assumes no obligation to update them. Now, I'd like to introduce John Kibarian, PDF's President and Chief Executive Officer, and Greg Walker, PDF's Chief Financial Officer. Mr. Kibarian, please go ahead..

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

Thank you and welcome everyone. Today I will start our discussion with a brief summary of our third quarter results. Then I will provide some perspective on the semiconductor environment and PDF Solutions' performance towards its strategic directions. Next, turn the call over to Greg who will walk you through the financial results in detail.

We'll then take your questions. In Q3, we continued the strong bookings performance for our solutions business that we have seen in the prior quarters this year. Non-GAAP solutions revenue increased 25% during the quarter. This was driven by growth in our Exensio Big Data Solution.

Gainshare revenues at $6.6 million, however, declined by 27% when compared to Q2. As we have stated before, Gainshare revenues are directly related to wafer production volumes shipped by our large customers. As a result, it can be highly volatile and this year has been adversely affected by significant declines in volumes of the 28 nanometer node.

While utilizations declined in some factories more than others, it was evident across the majority of our foundry customer base and seems to be consistent with the reported utilizations across this industry.

While we continue to remain positive on 28-nanometer over the long-term and eventually expect volumes to recover, until our customers can increase the utilization rates for their 28 nanometer production facilities, our Gainshare results will remain volatile.

Looking at other advanced nodes, our key customers made good progress on their 14 nanometer ramps and we should start to recognize 14 nanometer Gainshare in Q4. This bodes well for good 14 nanometer Gainshare in 2016.

As you probably are aware, we manage our business based on a financial model that focuses on solution revenue alone for funding the lion's share of our expenses. Looking at solutions bookings and revenue both for the quarter and the year, we are very pleased with the results.

While Q3 bookings were very strong for our growing software business, we also saw solid bookings for our expanding solutions business in Asia. Additionally, much of this new business was both across a variety of process nodes ranging from advanced development work at 10-nanometer to mature nodes as large as 90-nanometer.

The major contract signed in the quarter included a new technology development engagement at the 10-nanometer node with an existing foundry customer, a new technology development engagement at the 28-nanometer node at a new foundry customer in Asia, a multi-element engagement that included Characterization Vehicles and delivery of our Exensio Big Data Solution for more than more foundry in Japan, a new license of our Exensio Control software for the next phase of fab expansion for a large foundry customer in Asia targeted for future 10-nanometer production, additional new software license purchases and extensions of our Exensio Big Data Solution at 13 customers, and software and support maintenance renewals at nine Exensio customers.

Last quarter, I pointed out three key trends in the semiconductor industry that are critical to PDF.

These are, the proliferation of new derivative nodes driven by more than more applications of ICs, the shift of investment and development activity within the semiconductor industry in Asia and specifically China, the technical and economic challenges of in-line process control for leading edge processes i.e. those at 16-nanometer and below.

I went on to state that addressing the ramifications of these three trends would be the key focus of our overall business strategy, resource allocation and investments for the foreseeable future. Everything that we have experienced during the last quarter is convincing us that we're on the right track.

The types of engagements where we are seeing the highest value for both our customer and PDF are those engagements where combining our capabilities in big data, electrical characterization and in-line process control. These multi-element transactions are being driven by customers having to deal with issues created by these key trends.

A rapid expansion of investments in China semiconductor market is accelerating needs of these customers to address these trends quickly. With the addition of Exensio-Test and Syntricity, we are extending our reach into the OSI and test market.

This allows us to more effectively address the needs of our fabless and IDM customers and deliver on our promise of the virtual IDM. Each quarter this year I have provided an update about our Design for Inspection, sometimes referred to as DFI solution.

As a reminder, Design for Inspection solves the ever-increasing challenge of inspecting production chips for electrical defects. Conventional inspection allows you to see a visual difference and patterns on a chip.

However, many electrical faults are not visually inspectable and things that appear to be visually different may not result in a chip failure. Design for Inspection changes the entire paradigm for inspection by placing small on-chip instruments in the empty space in a product design.

To read these on-chip inspectors, PDF Solutions has been developing a new machine which charges these inspectors and reads the electrical responses. A typical product wafer will have 5 to 10 billion of these instruments. Our Exensio Big Data Analytics software can then identify the failing instruments and provide a yield signature for that wafer.

We reached a number of significant milestones in the past quarter. First, we had another test chip tape-out with DFI instruments. Second, our lead fabless customer taped out two 14-nanometer complete product chips with DFI. Each has over 7 billion instruments per wafer. These are our first product full production chips.

Third, we received wafers from two factories, one of which is at 10-nanometer and successfully use our beta tool to read the instrument's electrical responses. Over the next quarters, we look to increase our demonstration activity with fabs as well as have more fabless customers include DFI on their test chips and product chips.

We believe we are on track to start having business impact with DFI by the end of 2016 with the aim to expand the business in 2017.

In summary, our Q3 results and level of business activity confirm that we are continuing to drive the adoption of our solution at the leading edge nodes while expanding into solutions for more mature nodes and derivatives, commonly referred to as more than more.

Moreover, with our test solutions, we are extending our value proposition to our fabless and IDM customers by addressing their control needs based on and leveraging the process control platform we have built for foundries. We had success in closing our business in Asia and in particular in China this past quarter.

Finally, we are reaching significant technical and market milestones with Design for Inspection as our fabless customers expand our deployment of on-chip instruments and we demonstrate the capability of our systems to the market.

In summary, we believe we have focused PDF Solutions on the opportunities and challenges in the industry that are significant and valuable. Now I'll turn the call over to Greg to discuss in detail our financial results for the third quarter.

Greg?.

Gregory Walker

Thanks John. As a reminder, in addition to using GAAP results when evaluating PDF's business, we believe it is also useful to consider our results using other non-GAAP measures. For internal purposes, the Company focuses on non-GAAP net income and EBITDAR.

Non-GAAP net income excludes nonrecurring items, stock-based compensation expenses and amortization of expenses related to acquire technology and other intangible assets and their related tax effects as applicable. Additionally, the income tax provision has been adjusted in our non-GAAP net income to reflect cash tax expenses only.

EBITDAR is equal to earnings before income tax adjusted to exclude nonrecurring items, depreciation, amortization and stock-based compensation. You can access the earnings press release that contains a reconciliation of EBITDAR and non-GAAP net income to GAAP results in the Investors section of our Web-site located at pdf.com.

Now let's look at the financial results. Total GAAP revenues for the quarter were $23.9 million resulting in GAAP net income of $1.5 million and GAAP EPS of $0.05 per fully diluted share. Revenues on a non-GAAP basis totaled $24.4 million with non-GAAP net income of $5.8 million or $0.18 per fully diluted share.

Cost of sales and operating expenses together were $21.2 million on a GAAP basis and $17.7 million on a non-GAAP basis, which represents an increase in non-GAAP spending of approximately $1 million over Q2.

Moving onto revenue details, as stated above, total GAAP revenues for the quarter were $23.9 million, which were reduced by approximately $500,000 of non-GAAP deferred license and services revenues related to the Syntricity acquisition. Total non-GAAP revenue of $24.4 million for the third quarter were $1.2 million higher than in Q2.

Total non-GAAP revenues were comprised of Design-to-silicon-yield solutions or solutions revenue of $17.8 million and Gainshare performance incentive or Gainshare revenues of $6.6 million. Our top 10 customers represented 89% of total revenues in the current quarter.

One of these customers contributed revenues greater than 10% for a total of 60% as compared to two customers and 70% in the prior quarter. Looking at solutions revenues in more detail, 14 project-based engagements contributed at least $100,000 of solutions revenue in the quarter, two more than in the previous quarter.

Additionally, the total number of software customers increased during the quarter to 86 from 51 in Q2. Overall, solutions revenue at $17.8 million was $3.6 million higher than in the previous quarter.

This quarter over quarter increase primarily reflects strong organic growth in our software business plus the addition of software revenues from the acquisition of Syntricity during the quarter. Gainshare revenue for the quarter was $6.6 million, a decrease of $2.4 million from the prior quarter.

As John stated, this decrease was primarily driven by declining 28-nanometer volumes at several of our foundry customers. The total number of node sites which we define as individual fab and process node combinations contributing to Gainshare revenue in the quarter were 17, the same as in the prior quarter.

On a geographic basis, North America accounted for 54% of total revenues, which is up 5% over the prior quarter; Europe accounted for 26% of total revenues, a decrease of 6% from the prior quarter; and Asia accounted for the remaining 20% of total revenues, an increase of 1% over the prior quarter.

Moving to expenses, cost of sales for the quarter was $10.3 million on a GAAP basis, which was approximately $360,000 higher than in the previous quarter.

This increase in GAAP cost of sales was driven by higher headcount as a result of the Syntricity acquisition, increased stock compensation expenses and amortization of acquired intangibles from the Syntricity acquisition. GAAP gross margin was 57%, the same as in the previous quarter.

On a non-GAAP basis, cost of sales was $9.1 million, which was approximately $160,000 higher than the previous quarter. This increase in non-GAAP cost of sales was principally driven by the higher headcount due to the Syntricity acquisition.

Total GAAP operating expenses at $10.9 million were approximately $1.3 million higher than the last quarter and approximately 46% of total revenues which is 4% higher than last quarter.

R&D expenses totaled $5.2 million, approximately $700,000 higher than the prior quarter, and R&D expense as a percent of revenue was 22% in this quarter compared to 19% in Q2. SG&A expenses totaled $5.7 million or 24% of total revenues compared to $5.2 million and 22% of total revenues in the prior quarter.

Included in SG&A for Q3 on a GAAP basis is approximately $670,000 of acquisition related expenses. This overall GAAP operating expense increase was primarily driven by compensation expenses related to headcount increases in our R&D and sales and marketing organizations.

On a non-GAAP basis, looking at operating expenses and cost of sales together, total spending was $17.7 million versus $16.7 million in the prior quarter, an increase of $1 million, and as I stated earlier this was principally due to compensation expense related to increased headcount.

The GAAP income tax provision for the quarter was $1.3 million, which reflects an effective tax rate of 46% compared to 42% in the prior quarter.

This rate increase is due to the recognition of approximately $600,000 of non-deductible acquisition related expenses and the decrease in this quarter's actual pre-tax net income due to lower than expected revenue from Gainshare without a corresponding decrease in cash taxes.

As we have stated before, our cash taxes are primarily comprised of foreign withholding taxes and therefore did not reduce during the quarter. Overall, our full year outlook for the GAAP income tax provision rate is projected to be in the 39% to 41% range.

Of the $1.3 million of tax provision in the quarter, approximately $1 million represents cash tax liabilities. This represents an effective cash tax rate for the quarter of 36% of pre-tax GAAP income. For the full year, we still expect cash tax rate to be in the range of 20% to 22%.

GAAP net income of $1.5 million for the quarter resulted in GAAP EPS of $0.05 per fully diluted share compared to $2.1 million and $0.07 in the prior quarter. This reduction in GAAP EPS and net income is related to the reduction in Gainshare revenues and the one-time costs incurred for the Syntricity acquisition.

EBITDAR, which I defined earlier, is also defined in our press release, was $7.4 million in the quarter as compared to $7.2 million in the prior quarter. EBITDAR per fully diluted share was $0.23 compared to $0.22 in Q2.

On a non-GAAP basis, net income was $5.8 million and non-GAAP EPS was $0.18 for the quarter, compared to $5.9 million and also $0.18 in the prior quarter. Total cash at the end of the quarter was $126.3 million, a decrease of $5.4 million when compared to cash at June 30.

Cash generated from operations during the quarter was $5.3 million and approximately $500,000 of cash was received related to stock option exercises in the ESPP shares during the quarter.

This cash generation was offset by $5.2 million paid for the Syntricity acquisition, $4 million of stock repurchases and $1.6 million of fixed asset purchases mainly related to our tester programs and Design for Inspection initiatives. As mentioned above, the Company repurchased approximately 317,000 shares of its common stock for $4 million.

After these Q3 repurchases, up to $15.4 million remains available for use by the Company under its Board approved stock repurchase program. Trade accounts receivable DSO was 76 days for the quarter compared to 81 days in the previous quarter.

Trade accounts receivable balance at the end of the quarter was $19.9 million, a decrease of approximately $800,000 from the previous quarter. The unbilled accounts receivable balance was $12.6 million, an increase of approximately $900,000 over the prior quarter.

Of the $32.5 million of total receivables outstanding, approximately $700,000 or 2% was more than 30 days past due. Since the end of the quarter, $1.7 million has been collected to date. Total DSO for the quarter, including unbilled receivables, was 124 days compared to 127 days in the prior quarter.

Headcount at the end of Q3 was 391 compared to 360 at the end of Q2. This headcount increase primarily reflects the impact of the Syntricity acquisition and hiring in the R&D organization. In Q3, we continued to see strong solutions business activity on a worldwide basis.

Much of this improvement is in sales of our Exensio Big Data Solutions and continued new business in Asia. Overall, we remain positive regarding the solutions business for the remainder of the year. In regards to Gainshare revenue, we expect 28-nanometer volumes to remain depressed for the rest of the year.

As John indicated, the 14-nanometer ramp at our major customers is proceeding well and we expect to see our first Gainshare revenues from this node in Q4. Now I will turn the call back over to the operator for Q&A.

Operator?.

Operator

[Operator Instructions] Our first question comes from Jon Tanwanteng..

Jon Tanwanteng

I just wanted to focus on the solutions revenue. Could you break out how much Syntricity added and if you pulled in anything from future quarters at all? The numbers are pretty strong..

Gregory Walker

I think when we announced the Syntricity acquisition and talked about it, we were saying we are expecting approximately $800,000 or so for the quarter in revenue depending on the exact date of closure because you only get a prorated portion of the quarter, and we are in that range..

Jon Tanwanteng

Okay, and can we expect that degree of strength in solutions continue as we head into the next quarter?.

Gregory Walker

What I would say is for the full year we expect the strength, quarter to quarter variances too hard to call because we don't know where percentage of completion revenue is going to end up..

Jon Tanwanteng

Okay.

And then just from a higher perspective, is the strength in solutions indicative of more Gainshare strength down the line?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

Obviously that's the goal, right. So we engage in these activities to drive Gainshare and future revenues on these accounts..

Jon Tanwanteng

Okay, great. And on the Gainshare side, 20-nanometer obviously is not doing so great.

Do you have any visibility on as to when that may start to recover?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

No. We went to this year expecting it to improve in the second half, and obviously with these Q3 results, it degraded from the first half to the second half which I think the industry overall starting if we do that. Obviously got through the year, I think in the summer it start becoming more evident.

We don't have great visibility about when it turns up, in part because the parts that drove volumes in 2014 will not be the parts that drive designs that drive volumes in 2016.

I think a lot of the mobile communication devices and computing will move on to 14-nanometer, 16-nanometer in 2016, and that will be the next wafer part to drive the volume in 28-nanometer, and that's harder to forecast when new designs hit success..

Jon Tanwanteng

Okay, thanks. And then just on the 14-nanometer node, can you give us a little more color on the competitiveness of your customers' products in that arena? We've seen some media reports on just the way the Apple iPhone processors have been supplied and the performance differences between them.

How much of what you guys do is responsible for that difference in performance or maybe what it didn't do for your customers?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

So of course we got to be careful about talking about any specific customer that are under NDAs, but our vehicles do characterize parametric variability. We have seen parametric variability as you go down in nodes become a bigger and bigger and more important contributor to the overall performance and yield of the parts.

We have provided as part of that a Design-for-Manufacturability solution we call Templates.

I expect later on this year or early next year to be talking a little bit about the success our customers have had on parametric variability that have employed a Design-for-Manufacturability solution on these nodes and have gotten phenomenal parametric behavior.

But design has a big impact on parametric yields, and I don't know the specifics of that design but modellers does typically vary when it comes to design element. With our Template solution we've seen great results but I imagine a design that uses more varying layout styles will see a lot more variability..

Jon Tanwanteng

Okay.

And then maybe just a little bit more color on the dissolved partnership and what that means to your business?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

That's a great question, Jon. So earlier this past year we acquired the assets of Salland which had software products in the test area. Very good products, they had a lot of market share in the mixed-signal analog market. A lot of our existing customers for Exensio, previously our [indiscernible] customers were selling customers as well.

One of the things that we saw right away with that product like many small software companies is they can't make the investment in the product that you need. So they can do something really cool in code and they need to make sure it works on all the tester platforms.

Tessolve has because of its business with Qualcomm, Broadcom, most of the major fabless companies, it has tester platforms that it uses to develop software programs for those customers and we're working with Tessolve in first part to improve the software function on the existing tester platforms.

And secondarily, Tessolve has 800 engineers working with all the largest test and assembly houses around Southeast Asia and that's a bigger number of employees than we have, and we're working with them as related to sales channel for the OSATs in that part of the world, part of the world that we don't typically have PDF folks today..

Jon Tanwanteng

Have you seen any traction from that so far or is it too early to say?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

We think it's a little bit too early to say on the traction. We certainly have had joint customer meetings as a result of our engagements with them and there definitely seems to be interest in our products.

And in terms of the software, I think we do see big improvements and our customers have told us they see a huge change with the Salland technology as part of PDF and now Exensio-Test than it was when it was a small independent company..

Jon Tanwanteng

Okay great. Thank you very much..

Operator

Your second question comes from Tom Diffely with Davidson..

Tom Diffely

So just getting back to the Gainshare drop-off, how much of that do you believe is just the number of units going down versus a transfer from 28-nanometer to 14-nanometer and then the lag of between when you get the royalties at 14-nanometer?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

It's a great question, Tom. We know some of the end customers that drove that decline, and at least in one case they are not really up on 14-nanometer yet. So we do believe it was truly an inventory correction for probably one of the bigger customers that contributed to that volume decline.

They we know have active activities on 14-nanometer and we expect them to start driving volume in 14-nanometer as we get into 2016, but I don't think they were so much of it. The other big driver on the 14-nanometer, 16-nanometer node so far has been the application processes that go in the Galaxy and iPhone launches.

That shift has already happened from 28- nanometer over a year ago. So we believe this is primarily around inventory and weakness in some of the fabless customers' products in a couple of the end markets..

Tom Diffely

Okay.

And even though some of your customers have these take or pay contracts, you don't see any kind of uptick in the fourth quarter from that?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

The take-or-pay we think has driven kind of a slower level of volume at at-least one of our customers and we believe that is providing some level of demand inside the factories. It's the more classic fabless customers who don't have those arrangements that buy wafers on demand where we see the weakness..

Tom Diffely

Okay.

And then if you look at the, how to phrase this, the Gainshare producing foundry capacity out there for you, has that gone up this year or how is the total capacity of your Gainshare potential?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

That's a great question, Tom. So I think there's a couple of things. In a lot of our foundry customers, the expansion in 14- nanometer or FinFET nodes is in new foundry capacity. So they are building entirely new show.

They may do some startup of 28-nanometer in that show but it quickly shifts onto the FinFET node because the tooling set is designed to that.

The IDM types or kind of the hybrid IDM foundry types, sometimes they repurpose 28-nanometer capacity into advanced nodes, and we know that at least one of the technology leaders is doing that where they are repurposing the capacity. When you repurpose the capacity, the unit volume tends to go down.

In other words, the factory that could produce 50,000 wafer starts at 28-nanometer will not produce 50,000 wafer starts at 14-nanometer because the total number of processing steps goes up. So I would say for most of our customers, the newer nodes are greenfield capacity.

With one particular exception, we believe that a lot of their new capacity at 14- nanometer has come at the expense of their 28-nanometer..

Tom Diffely

Okay.

So if the foundries all produce at full capacity or were producing at full capacity today, would you have record royalty revenues?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

Yes, if everything were for right now, we would be blowing the doors off..

Tom Diffely

Okay, we'll look forward to that next year. So, on the Syntricity acquisition, you talked about the 800,000 in the quarter.

What is the kind of average quarterly run rate?.

Gregory Walker

Probably a little bit higher than the 800,000, is kind of what we are taking over..

Tom Diffely

Okay.

And then Greg, when you look at the OpEx structure right now post acquisition, does that feel like a structure that's going to be roughly the same going forward?.

Gregory Walker

I would say certainly within 5% to 10%, up or down, on the standalone Syntricity resources. When you look at the combined companies, we will be making additional investments. Hard to say whether at that point in time are we hiring Syntricity – new Syntricity or new PDF, they are basically combined at this point in time..

Tom Diffely

Okay. And then I guess lastly, Greg, you talked about I think it was $1.6 million for some test equipment.

Is that not simply part of R&D?.

Gregory Walker

Depending on what stage the development on that hardware is, it can be either R&D or cost of sales. So if we have a completed design we are in production on, we're just building new equipment like a new tester that is already in the field, that would go against cost of sales..

Tom Diffely

Okay.

And would you expect to have a significant ramp in tester equipment expenses for next few quarters as you kind of build up your DFI?.

Gregory Walker

It will be referred to as something other than tester, but yes in the same line..

Tom Diffely

Okay. Alright, thank you..

Operator

Your third question comes from Brian Freckmann with LS Capital..

Brian Freckmann

Greg, can you please repeat your commentary [indiscernible] for the fourth quarter in regards to design-to-silicon? I wasn't quite sure what you were insinuating as to the run ate from the third quarter..

Gregory Walker

So for one thing, as you know, we don't really give out quarterly guidance or expectation. So we reiterated the fact that we are expecting the full year to be strong.

As far as what the next quarter will be, it's too hard to call an exact number or even within a range because there's a lot of variability driven by the percentage of completion recognition depending on how much work against our customers' timetables actually gets done.

So there's quite a bit of variance there, but overall, yes, we're three quarters into the year, we know what that is and overall we feel good about the full year number, which implicitly says we feel reasonably good about the quarter. Will that be up or down from this quarter? There will be variance around that, can't say..

Brian Freckmann

Any way to sort of even just give us a range of the variance in your view, like is it 10%, 20%? I mean this is certainly a benefit to the upside, a big number, and I think just trying to make sure fourth quarter is in line..

Gregory Walker

So what we've said before was we expected the year-over-year growth to be in the 5% to 10% range, closer to the high end of that range. We would certainly reiterate that guidance. So that's the way to figure out kind of bottom end of the range..

Brian Freckmann

Okay, that's good.

And then just sort of in looking out at the Gainshare business for sort of trying to look at calling a bottom here, which I think, John, it sounds like you're actually sort of kind of positive on this quarter versus last quarter, assuming kind of an equal number of 28-nanometer business, if we take into account 14-nanometer, is the expectation that Gainshare should be up in the fourth quarter just kind of directionally?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

So if 28-nanometer volumes do not erode further, then with 14-nanometer orders we should see an improvement in Gainshare. That's because it's out of new capacity. Like we said, we are still – 28-nanometer is murky to us right now.

We are trying to keep – we expected Q3 to be an improving 28-nanometer quarter when we got into Q1 and it turned out not to be. So with that caveat, should 28-nanometer stayed at the same level they are right now, with 14-nanometer orders we should see an improvement.

If 28-nanometer erodes more, then it's going to eat into our – the gains that we are going to get off 14-nanometer..

Brian Freckmann

Okay.

And then did I hear this right, Greg, when you said your non-GAAP revenue was 24.4?.

Gregory Walker

Correct..

Brian Freckmann

Okay, it's non-GAAP revenue, okay.

And then finally, is there any way to sort of think about, if we sort of bundle – I know DFI is not for a little while, but some of the sort of let's call it newer initiatives whether it's big data within the design-to-silicon business, sort of disaggregate to two sort of say core legacy PDF and design-to-silicon, sort of help us understand sort of what benefit – I mean you guys talked about these new initiatives for quite some time, I think some of us would like to begin to see sort of, hey, this revenue generated a certain percent potentially with the design-to-silicon business, we're getting rewarded for things we've been investing in for last few years, any way to sort of break that out?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

It's hard to do, Brian, because if you look at for example the more than more foundry in Q3, it's an integration of CVs and the big data solution and how much of it do we attribute to each. What I think you can look at is the growth in the solutions business is greatly due to the new technologies.

So if you kind of look year-over-year growth, it's mostly off the new products and new solutions that are making it some more relevant to the mature nodes, to the fabless companies, to their control, test control problems, et cetera. And you are right, there is really no revenue.

All Design for Inspection right now is a drag on earnings because we're making that investment now. So it's not contributing to the top line. But the majority of the growth year-over-year is related to that, to new investments. Moreover, if you kind of look at the capital equipment industry, it was really dependent on advanced nodes.

Most of the capital equipment industry this year has seen not a lot of growth in selling new equipment, and typically our business has really – the solutions part of the business has correlated with when capital goes into factories, and the Gainshare has typically moved with the application of that capacity, typically much after the capital equipment folks see their revenue from installing equipment.

And what's been interesting for us this year is our business on the solutions side has been going up strongly while the capital equipment business which is really tied to the advanced nodes has not been going up as strongly, and I think that really speaks to how we're de-coupling the solutions business from the leading edge really very – some of it was about 10-nanometer this past quarter but not the lion's share of it.

So I think that should give you comfort that the investments we are making are going in the right direction, but it's kind of hard to peel it out, and frankly when inside the Company, people want to, how valuable is my product versus that product.

My argument to them is, what's more valuable, your heart or your lungs? I don't see anyone living without a heart and lungs. So we're not going to live as a company without a heart and a lung. So let's not talk about how much you get versus how much the other guy gets. That's my mother of an apple pie approach..

Brian Freckmann

Okay.

And then finally just on DFI, have you guys sort of come to a conclusion on sort of how you're going to be charging for that?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

No, we are really not ready on that yet but we are getting – for the first time we're starting to get measurements and we're starting to the kind of problems that we can see for customers and they are really excited about everything. Subtle leakages that are typically very hard to see on inspection.

One of our fabless customer friends says, detect the undetectable and we really are seeing things that are undetectable on inspection. So it's really quite complimentary to the inspection capacity that's out there. I think it will be very valuable for customers. But how we price for it, we still don't know yet. We want to get more data..

Brian Freckmann

Okay, sounds good.

And then maybe since I don't know if anyone's behind me, the $4 million in buyback on a 2015 total, given what looks like a pretty strong 2016 for 14-nanometer, I'm curious what has been the rationale for $4 million versus let's say $10 million, or sort of at the level you guys are buying, what's been the rationale to do $4 million versus a much larger amount?.

Gregory Walker

This is Greg. I think two things. One is there is a limit on how much we can buy just based on probably the last 30-day average trading and so forth. So that limits us somewhat. Two is, you don't want to go in where you are moving the market, so we're careful about that.

And three is, really at the Board level there is still enough discussion going around about how aggressive to be on buybacks that we are taking a relatively cautious approach to how we do that..

Brian Freckmann

Okay, thanks for the color. Appreciate it..

Operator

[Operator Instructions] Your fourth question comes from Gus Richard with Northland..

Gus Richard

Can you give me some color, what was the software revenue in the quarter?.

Gregory Walker

We don't separately disclose that. So part of that is due to the fact that a lot of the deals are combined. It gets very grey as to what software versus what's IYR type work. I think John was talking about one transaction where we've got a combination of almost everything we do in the deal.

So for that reason, we have not separately identified the software business, and at this point in time we don't have a plan to..

Gus Richard

Okay.

Would it be fair to say that about I'd say 20% of the revenue from design-to-silicon solutions was software, is that a ballpark, and it's growing as a percent?.

Gregory Walker

I hesitate to say whether that's ballpark or not because of the crossover between the two. Depending on what allocation methodology I use in some of these deals, I can come up with wildly different answers..

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

But I think, Gus, to get at the question, I think the way you might want to think about it or the way you certainly think about it, the value of the software that's being delivered in the solution is a greater and greater percentage of the total business, and that is giving us efficiencies in that we are able to deliver more value to the customer without growing the field at all like our field.

The number of consultants or field folks in the organization has been around 70 folks and it continues to be at that level yet as you look at the design-to-silicon-yield solutions revenue is up substantially over where it was let's say a few quarters ago on the same field expense. And we are trying to improve that.

What I really liked about the Syntricity business was they were delivering software as a service, right. So we want to find more ways to serve the customer where we drive value to the customer that doesn't involve headcount, and I think that's kind of what you're seeing in the numbers, but how to split it back out is very hard to do.

The Syntricity thing, do you call that service, do you call that software. Certainly, it's software enabled service..

Gus Richard

Okay, I get it. And then I think you announced two contracts, one for 10-nanometer design-to-silicon solutions with an Asian customer.

Did you recognize revenue in the quarter from that contract or is that to come?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

I think that was from a foundry customer. We didn't say who or what part of the world it was from, and that we did recognize revenue in the quarter. The other we're going to control..

Gus Richard

Okay. And I think you had also a 28-nanometer customer, I think you said in China. [Indiscernible].

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

Yes, that was in China. We did recognize some revenue from that customer..

Gus Richard

Okay, perfect. Thank you..

Operator

Your fifth question comes from Andrew Wiener with Samjo Capital..

Andrew Wiener

Greg, first I just wanted to clarify something.

The guidance on solutions is for half the year is 5% to 10% growth and I think you said you are very comfortable with the high end of that, and that backs out the first quarter contribution from the payment from the customer from the contract issue from last year, correct?.

Gregory Walker

Correct..

Andrew Wiener

Okay.

Secondly, John, over the last couple of quarters, just a little bit of a follow-up to Tom's question earlier, you talked about your ability to get in with some customers in Asia, in particular China, and perhaps you can talk about how you see over the next couple of years that adding to the Gainshare potential for the Company?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

Sure. Actually in our prepared remarks and to refer to the [indiscernible] because right now the business we talked about this past quarter was for a company that was headquartered in China, but we also see a lot of our Taiwanese customers making expansions into China. So broadly Greater China, we see a lot of activity.

Foundry capacity is going in there, currently at the 28-nanometer node initially and we believe there is some R&D activities that we are seeing in FinFET nodes. We see that part of the market wanting to move very fast on buildout of capacity we bring up and needing to get to the worldwide competitive status quickly.

In that regard I think we have a wonderful offering for them because we have a proven infrastructure on these advanced nodes from development, Design-for-Manufacturability through process control and production control. So we started out about a year ago making introductions, we did some pilots in the first part of this year.

This contract we signed in Q3 is the first conversion of a pilot into a contract and we anticipate others as we go through the remainder of this year and into next year. Our activity started first with the fabless entities and we see good activity there. We believe that will be kind of the way that China moves into the leading edge nodes.

We’ll start with the fabless and system companies, or have started I should say. And then it will also permeate to the foundries and we believe PDF could be a very important bridge between those fabless and system companies and the foundries themselves..

Andrew Wiener

And when you look at their plan sort of in aggregate, and I realize this is not a forecast of your results per se, but if you think about wafers per month under contract or something like that from Gainshare perspective, if they were to execute against sort of their stated plan, what does that do to the overall number of potential wafers that you are entitled to –you potentially be entitled to gain share on if you wanted to [wait out] [ph] two or three years?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

So of course you know the stated is about 60% of what their funds are putting – what the China government is investing is going into the front-end manufacturing and 40% goes into design, test and assembly.

If you took the numbers that they are quoting and they are gargantuan numbers like in the tens of billions of dollars and put 60% of that into capacity and take all of these things that they are forecasting and to put in the volume, yes, then it would be a huge – it would dwarf the amount of capacity that we have under contract today and should we then capture that business.

So I think you've got – certainly we take a healthy dose of realism, and say, okay, we have to be careful about how excited we get about this.

There's certainly a potential for a lot of capacity to go in there, and if they spend the money they said they're going to spend on capacity on the front-end primarily at 28-nanometer and below, it represents a tremendous opportunity for us and a opportunity that would be as larger or much larger than the factories that we have under contract today..

Andrew Wiener

And when I think about your business model, are you generating enough solutions or design-to-silicon revenue at this point in China where you are recouping your sort of cost of capital there or are you still in the investment mode in China?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

It's a great question and one we asked ourselves earlier this week, and we haven't gotten an answer yet. We just think, okay, let's go back and look at what our investment been on the pilots so far, and now that we're starting to sign contracts how is this going to look over the next 12 quarters that [indiscernible] still on invest mode.

We got to try in 2006, right. We made the decision to go to China in 2005, we got there in 2006, and we invested in engineering team there. We now have 120 folks in China, almost – I don't know what that works out to be, it used to be 33%, but slightly less than that of the Company. So we've been investing in a very long time in China.

So we're not impatient. At the same time I think we're now starting to turn the corner. I don't think – we're not very many quarters away from that being a meaningful part of our business..

Andrew Wiener

Also, as a follow-up, you referred to I guess a foundry that's perhaps a hybrid IDM who was transitioning 28-nanometer to 14-nanometer. From a standpoint of how we think about that as being replacement versus incremental, they have actually been running I believe at very low levels of utilization for a number of quarters now.

So to the extent we start seeing 14-nanometer revenue from that customer, it's fair to say versus our current rate that it would be largely incremental?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

That's correct..

Andrew Wiener

Okay. Next question I had was, again you historically have said that design-to-silicon sort of pays the bills and Gainshare is where the profitability comes in.

However, to the extent that software is an increasing portion of the design-to-silicon revenue and it's being sold not just to foundry customers or foundry customers for which we have integrated solutions contracting a gainshare, but I believe it's also being sold to foundries where we don't have a gainshare contract as well as it's being sold pretty broadly now to fabless, should we expect over time that the design-to-solutions actually runs profitably and is incremental to the profits of Gainshare?.

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

You could have entered the meetings earlier this week, Andrew. Yes, it's actually something we're trying to model out. We've got two competing things there. Most of the business is ratable. So you make an investment in the field to see that business. You book a couple of million dollar contract and you see in that quarter maybe $100,000 or $200,000.

So we are trying to in the field as we're doing our strategic planning, reporting on where they saw a business opportunity around the world in terms of Exensio Big Data and there was quite a number of potential business, potential clients, the customers in a variety of all of our geographies, Asia, Europe, U.S., and so we are trying to balance our investment levels to get at that business versus the profitability we drive off that business and understand a little bit about that trade-off.

If you go to the steady-state, yes, our goal and the reason why we started making this investment is, we want to drive profitability of design-to-silicon solutions business irrespective of Gainshare. We want to get to a model eventually where that covers not just our expenses and our investments but also drives profitability.

We are not there yet obviously and we don't know quite how long it's going to take us to get there, because as I said we are balancing investment in the channel versus immediate return and we're trying to understand that, but for sure that is the reason why we made that investment..

Andrew Wiener

My last question is, if I was trying to – and then I'll pass it on to the next person – if I wanted to try to figure out the profitability of sort of classic PDF including software and sort of break out the spend on Design for Inspection which is really sort of a new opportunity and which there is no revenue attributable today, what percentage of the operating expenses would you say is attributable to the DFI initiatives?.

Gregory Walker

I would certainly think it would be no more than 5% at this stage of our total spending and probably in that range. I'm sorry, that's as a percentage of revenue. As a percentage of revenue, it would be no more than 5%..

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director

I think another way to look at it is the majority of the growth in the R&D line has been Design for Inspection.

So if you compare 2014's spend level with 2015 spend level, the majority of that Design for Inspection, there was some Design for Inspection in our 2014 number and there was even some in our 2013 number, there were some very, very earlier in our 2012 number, but the majority of that growth has been Design for Inspection related activity..

Andrew Wiener

Thank you..

Operator

Your last question comes from Mike Cotogno with Cardinal Capital..

Michael Cotogno

Just one quick one, on the Gainshare revenue moving back a year, so my guess is that 28-nanometer was probably a nice log of the composition of the Gainshare revenue. Right now in the current quarter or the most recently reported quarter, obviously things are falling off.

I mean is it safe to say that 28-nanometer is less than 50%, or can you give us kind of a rough range of where you think that's playing out right now?.

Gregory Walker

Gainshare, 28-nanometer still is the majority of the Gainshare revenues, but just the total amount has fallen..

Michael Cotogno

Okay, thanks..

Operator

At this time, there are no more questions..

John K. Kibarian Co-Founder, President, Chief Executive Officer & Director
