[John Kibarian:]

Thank you, and welcome everyone. If you've not already seen our earnings press release or written management report, please go to the Investors section of our web site, where both are posted. Today, we will discuss the first quarter of 2018, both business progress as well as the environment we experienced. I'll also describe the business environment we're anticipating for the remainder of the year in our response. First, let me summarize the significant contracts closed in the first quarter; an extension to a 7 nanometer IYR contract, a contract with an IDM for Exensio-Test, contract with an Asian foundry for Exensio-Control and many other contracts for Exensio platform and modules, including Exensio-Test and related services. The market opportunity at logic foundries in all geographies, including China, for the Integrated Yield Ramp solution, which we refer to as IYR, was softer in the quarter. Capital spending reports by semiconductor capital equipment companies indicate that the large spending was driven by memory fabs, while spending at logic foundries was weak. While we have some early adoption of our IYR solution at memory fabs, the primary market for IYR is still logic foundries. As we've been reporting over the past few quarters, with few exceptions, logic foundries has slowed down their investments, and we see the effects and that slowdown on decreased business activity in IYR solutions. We also continue to see mixed 28-nanometer volumes at logic foundries. As a result, our gainshare revenue continues to be lumpy. Beginning in Q1, fortunately, gainshare became the more significant note for gainshare revenue contribution, which we expect to continue through the remainder of the year. Our business activity in areas outside of logic foundries -- technologies continue to be robust. Our newer products, including new applications of our Characterization Vehicle infrastructure, applied primarily to more than more technologies are Exensio Big Data platform and our Design for Inspection, or our DFI solution, all continue to receive interest in the marketplace. In particular, we have a number of ongoing demonstrations of DFI, where we are testing customers wafers in our Milpitas facility. Exensio, while strong overall, is growing noble interest for applications that's our unique ability to improve quality in yield and multichip assembly. Overall, revenue from these newer products and services now make up about 50% of our Design to Solutions -- silicon solutions revenue. For DFI, the initial hardware development of our next generation tool, DFI tool, the eProbe 250 is complete and our focus is shifted to developing applications for customer's ramp and production control needs. While already meeting our goals for throughput improvement over the previous generation tool, we continue to make improvements beyond the capability of the eProbe 150 to find the logical defects that have importance to our customers. Most recently, the machine is demonstrating unique features, we believe are critical to inspect for mass production applications. As far as selling activity for DFI, we continue to design on-chip instruments for a number of applications and demonstrate capability on customers various test facilities. We expect such demonstrations to continue throughout the year. Importantly, we plan to release our fifth generation pdFasTest in the third quarter of this year. This generation is designed to increase our effectiveness at characterizing both commodity and embedded nonvolatile memories. We have a number of pilots ongoing with customers and some contracts already in place to take advantage of this innovative capability. This will present increased opportunities with embedded and stand-alone memory customers and more than more technologies. For the remainder of the year, we believe that business activity will continue to be in our solutions for fabless systems in more than more fabs. We anticipate spending in logic foundries, particularly second-tier foundries to remain soft. As yield ramp for second-tier logic foundries has been such a big part of our revenue, we expect that the softness in this part of the market will make 2018 a challenging year from a revenue perspective. As we look to the second quarter, we have a number of new customer selling activities, but the timing, during the quarter, is not clear at this time. Further revenue from DFI Exensio and contracts covering CV infrastructure, plus Exensio for legacy fabs, is primarily ratable, without a large bump in the quarter, in which the new contracts are signed. Hence at this point, you will see in our outlook in the management report, we are cautious about our expectations for Q2 revenue in comparison with revenue of the future quarters. As I have said on previous calls, we believe that for these legacy fabs that are using our CV infrastructure and for Exensio platform, primarily to control manufacturing, a ratable business model type usage, much like the model we are using for DFI and Exensio, allows us to better capture long-term value. We intend to continue selling yield ramp engagements with gainshare in cases with the customer's values tied to market -- values tied to time-to-market and our investment is heavy. As a result, the environment we are experiencing and the slower revenue recognition related to usage-based models, we took some actions in the first quarter to reduce spending, primarily related to yield ramp business in the U.S. and EU. As we move through this year, we will look for opportunities to further improve efficiencies and to further reduce spendings associated with our yield ramp business, particularly outside of Asia. Further, we experienced -- we expect spending on third-party development to begin the taper off over the next two to three quarters as spending associated with the now completed development of the eProbe 250 ends. Some of these savings will be offset by further investments, primarily in Exensio, with some additional investments in field applications for DFI. In summary, we are transitioning PDF's business from a dependency on the introduction of new notes, to value across the manufacturing lifetime. Moreover, we are bringing our technology that was primarily used at leading-edge fabs, up to the fabless and system companies. These changes are aimed at diversifying our revenue sources, returning the company to growth and providing more predictability to our financial performance. With this, I'll turn the call over to Greg.

[Greg Walker:]

Thank you, John. As you may have seen in our earnings release, we have posted in the Investor Relations section of our website, a management report with detailed comments regarding the financial results of PDF for the quarter. Given that, I'm going to focus my verbal comments for the quarter and a few key highlights reflected in those results. Looking at revenue first, as you are aware, the company has adopted ASC 606 or Topic 606 methodology for all revenue reporting, beginning with Q1 in 2018. The company has elected to implement this change using the modified retrospective method. There is a summary of the adjustments related to this change, which is published as part of our Q1 2018 management report, available in the Investor Relations section of our website. Additionally, a detailed description of all the adjustments, impacts and methodology changes related to ASC 606 will be included with our upcoming 10-Q filing. At the summary level, the major adjustments for Q1 are as follows

[Operator Instructions]. And our first question comes from Jon Tanwanteng with CJS Securities.

[Jon Tanwanteng:]

Good afternoon guys. Thank you for taking my questions.

[John Kibarian:]

Sure John.

[Jon Tanwanteng:]

Last quarter, you provided some growth bogeys for both gainshare and the solutions business. I know you're expecting it to be flat or maybe down this year with ASC 606, but can you break out those segments and maybe with DFI and Exensio in there as well?

[Greg Walker:]

Yes, I -- probably not of that detail, but I think, we did talk about gainshare. We were expecting it to be up slightly year-over-year. At this point in time, I think given the Q1 results, we're probably thinking more flat around gainshare, with Exensio and DFI growing and that growth being offset almost completely by decline in the yield ramp business.

[Jon Tanwanteng:]

Okay. Great. That's helpful. And then for DFI specifically, is there any update or change to the amount of 150 and 250 machines that you're actually planning to ship? Or to be revenue generating condition this year?

[Greg Walker:]

No change from our prior discussions on the number of machines or the schedule. We're still expecting to ship 250s around midyear or so.

[Jon Tanwanteng:]

Great. And then finally, just any other steps to improve DSOs from what you're seeing out there? Either any programs in place? Or is it just the nature of where you're doing business?

[Greg Walker:]

I think, it's really getting down to one or two customers. If you go look at the $11 million we collected after the end of the quarter, that brought, almost, all of our customers' balances to nearly current with the exception of two. One of which is very large foundry in China. Based on what we're seeing that they are, basically, slow on payment across the board not just with us. That's one that we are battling every day to get as low as possible. The other one is a situation where the customer has already agreed to pay, we're basically processing a tax filing through the government that's in Asia, that's taking some time to get clear, but it does save us money on withholding tax. So once that's cleared, we know that we'll get paid, which will really leave us, primarily focused on the one large foundry in China.

[Jon Tanwanteng:]

Great. Finally, just one more, can you just remind us how much more is remaining in your stock buyback program?

[Greg Walker:]

I believe, it's about $12 million at this point in time.

[Jon Tanwanteng:]

Great. Thank you.

[Operator:]

At this time, there are no more questions. Ladies and gentlemen, this concludes the program. Thank you for joining us today.

[Greg Walker:]

Thank you.
