Thank you for standing by, and welcome to the Schrödinger conference call to review the company's second quarter financial results. My name is Kevin, and I'll be your operator for today's call. (Operator Instructions)
Please be advised that this call is being recorded at the company's request.
Now I'd like to introduce your host for today's conference, Tracy Lessor, our Executive Director of Corporate Communications. Please go ahead.
Tracy Lessor
Thank you, and good morning, everyone. Welcome to today's call during which we'll provide an update on the company and review our financial results for the second quarter of 2021.
Earlier this morning, we issued a press release summarizing our financial results and progress across the company, which is available on our website at www.schrödinger.com.
Here with me today are: Ramy Farid, President and Chief Executive Officer; Karen Akinsanya, Executive Vice President, Chief Biomedical Scientist and Head of Discovery R&D; and Joel Lebowitz, Executive Vice President and Chief Financial Officer. Following our prepared remarks, we'll open the call for Q&A.

Ramy Farid - CEO, President & Director
Thanks, Tracy, and thank you, everyone, for joining us today. At Schrödinger, we have developed a computational platform that is transforming the way therapeutics and materials are discovered. The platform is enabling our customers and our internal teams to discover high-quality molecules for drug development and materials application faster at lower cost and what, we believe, a higher probability of success compared to traditional methods. We license our platform to pharmaceutical, biotech and materials companies and universities and government labs worldwide. As Karen will review shortly, we are also advancing an internal drug discovery pipeline and leveraging our platform in a number of drug discovery programs in collaboration with pharmaceutical and biotech companies.
We announced a new drug discovery collaboration this month with Zai Lab. The collaboration marks the first time we have the opportunity to codevelop and co-commercialize a therapeutic. Zai Lab has a deep pipeline in oncology with multiple approved products, and we are excited to be working with them. The collaboration with Zai will focus on a target in the area of DNA damage response, an important therapeutic strategy for a broad range of cancers and build on the knowledge we have gained working on our own programs in this area.
Under the terms of the agreement, Zai will make an upfront payment to help fund our share of research costs. We have co-development and co-commercialization rights that will allow us to share equally in the profits of a future marketed product in the U.S. if we choose to co-fund U.S. development. We are also eligible to receive up to approximately $338 million in preclinical development, regulatory and sales-based milestone payments as well as royalties on net sales outside the U.S. This collaboration provides us with the opportunity to gain expertise in late-stage clinical development and commercialization as well as the ability to participate more significantly in the downstream value of a program.
As you will hear shortly from Joel, we reported a strong second quarter with 29% revenue growth compared to the same period last year, and we ended the quarter with cash resources of $617 million. Our financial strength allows us to continue to invest in advancing our science, invest in growing our software business, advance our internal pipeline and add new talent to support our strategic initiatives. We are excited by the progress we've made as we continue to transform the way therapeutics and materials are discovered.
I'll now turn the call over to Karen for an update on our drug discovery programs.
Karen Akinsanya - Executive VP, Chief Biomedical Scientist and Head of Discovery R&D
Thank you, Ramy, and good morning, everyone. We are continuing to make important advances on many fronts across our internal pipeline and portfolio of collaborative programs. We have collaborations with both biotech and large pharmaceutical companies spanning a broad range of target classes. And in these collaborations, we are leveraging our platform at the same scale we do internally. We believe this level of large-scale deployment enables us to more rapidly identify high-quality development candidates. We expect several collaborative programs to continue to advance in the clinic and new programs to enter the clinic this year. We are excited to begin working with our new partner, Zai Lab, on a program targeting DNA repair vulnerabilities in cancer that we anticipate will be synergistic with PARP inhibitors. Marketed PARP inhibitors have demonstrated efficacy in multiple cancers but new regimens and combinations that result in durable responses are needed, especially in patients who relapse or become resistant to treatment. We are also continuing to build early-stage clinical experience to support the advancement of our internal program.
Today, I will highlight through our 3 most advanced programs MALT1, CDC7 and Wee1. We have initiated IND-enabling studies for our development candidate targeting MALT1, and we are working towards the nomination of development candidates for CDC7 and Wee1. Subject to completion of the preclinical data packages, we expect to submit up to 3 IND applications in 2022, with our first submission expected in the first half of next year.
Starting with our MALT1 inhibitor program. MALT1 inhibition is gaining increasing attention as a therapeutic strategy to treat certain relapsed or resistant B-cell lymphomas and chronic lymphocytic leukemia. The MALT1 enzyme is downstream of BTK in the NF-kB signaling pathway, and constant activation of NF-kB is a hallmark of several types of lymphoma. Preclinical data previously presented from our MALT1 program showed potent in vitro inhibition of MALT1 enzymatic activity and in vivo antitumor activity in mouse xenograft models of diffused large B-cell lymphoma. Additionally, in in vivo, patient-derived tumor mouse models, our MALT1 inhibitors demonstrated dose-dependent anti-proliferative effects as monotherapy and in combination with ibrutinib and venetoclax, which are approved BTK and BCL2 inhibitors, respectively.
In the second quarter, we selected a development candidate for this program and have since initiated GLP tox studies required for IND submission. All our IND-enabling activities are on track and we expect to submit the IND and begin Phase I studies in patients with hematological malignancies next year.
Now I'll turn to CDC7 and Wee1, two programs that target cancer through replication stress and DNA repair mechanisms. CDC7 is thought to be linked to cancer cells proliferative capacity and ability to bypass normal DNA damage responses, targeting proteins that play important roles in DNA replication and replication stress, is gaining momentum as a therapeutic approach for cancer. Earlier this year, we presented preclinical data from our CDC7 inhibitor program, which showed that our compounds are synergistic with several approved and investigational cancer therapies that modulate apoptosis, DNA repair mechanisms and DNA checkpoints. These compounds significantly inhibited tumor growth in mouse models of both acute myeloid leukemia and colorectal cancer. The data we have generated to date suggest that we have an opportunity to develop a best-in-class inhibitor with a very favorable pharmacokinetic profile.
Our other DNA damage repair program targets Wee1, a tyrosine kinase regulator of the G2M cell cycle checkpoint which, when inhibited, reduces cell viability by inducing apoptosis of cancer cells. Wee1 inhibitors from other companies have shown clinical proof-of-concept as monotherapy in vitro serous carcinoma. Combinations with chemotherapy, PARP inhibitors and PD-1 antibodies are being pursued by others in the clinic.
We have identified multiple Wee1 inhibitors that are highly selective for Wee1 and show strong pharmacodynamic responses and antitumor activity in vivo. Our molecules also have optimized drug-like properties, including no observable inactivation of CYP3A4, a key liver enzyme. We believe this profile limits the potential for accumulation and the need for dose adjustment of combination products.
In summary, we have multiple programs advancing towards the clinic to enable up to 3 IND submissions in 2022. As these programs advance and transition into development, we are initiating new programs. We have begun drug discovery on an undisclosed target in immunology and have prioritized several additional program opportunities with human genetic support and emerging pharmacology data in oncology and immunology that we expect to advance this year. We are excited about the progress that we and our collaborators are making, and look forward to updating you on our R&D activities throughout the year.
I will now turn the call over to Joel to review our financial results.
Joel Lebowitz - CFO & Executive VP
Thank you, Karen, and hello, everyone. This morning, I'm pleased to discuss our financial results for the second quarter of 2021, and I'll also review our outlook for the year.
We reported total revenue of $29.8 million for the second quarter, up 29% compared to the second quarter of 2020. Software revenue was $24.1 million, representing 15% growth compared to the second quarter of 2020. The growth in software continues to reflect increased adoption of our platform by existing customers and the addition of new customers. Drug discovery revenue was $5.7 million for the second quarter compared to $2.2 million in the second quarter of 2020. Second quarter drug discovery revenue included $3.3 million recognized from our collaboration with Bristol Myers Squibb. Discovery revenue also included a payment from a collaborator associated with the acquisition of intellectual property following the achievement of a lead optimization milestone.
Gross profit was $12 million in the second quarter of 2021 compared to $13.6 million in the second quarter of 2020. Software gross margin was 77% in the second quarter of 2021 compared to 82% for the same period in the prior year, reflecting our planned investment to drive and support long-term large-scale adoption of our platform.
Operating expense was $42.3 million compared to $30.7 million in the second quarter of 2020, reflecting our investment in R&D to advance our pipeline and our technology, the addition of staff to drive long-term software sales growth and expenses required to build a public company infrastructure and support the company's growth as we scale globally.
Other expense, which includes changes in the value of equity investments, was $4.6 million in the second quarter of 2021, driven primarily by a loss of $4.9 million from the mark-to-market of our shares in Morphic Therapeutic. This compared to $13.1 million in income for the second quarter of 2020. As we revalue our shares each quarter, we can experience significant fluctuations in the value of our holdings depending on stock price movements. The value of our shares in Morphic recorded on our balance sheet as of the end of the second quarter was $48 million, demonstrating the value we have helped create through this collaboration so far.
We recorded a net loss after adjusting for noncontrolling interest of $34.6 million for the second quarter of 2021 compared to a net loss of $3.4 million for the same period last year. This year-over-year change is driven by quarterly fluctuations in the value of our collaboration equity, particularly our shares in Morphic as well as planned investments in our business to drive long-term growth.
We ended the second quarter with cash resources of $617 million compared to $649 million at the end of the first quarter of 2021. In March, we provided our financial outlook for the full year, and today, we are reaffirming that guidance. We expect total annual revenue in 2021 to be in the range of $124 million to $142 million, which includes software revenue of $102 million to $110 million and discovery revenue of $22 million to $32 million.
Also, we expect the majority of our second half growth in software revenue to occur in the fourth quarter. Drug discovery revenue can be highly variable based on the timing of potential milestones related to collaboration agreements.
As we've said before, we anticipate that full year operating expense growth will be higher than the 42% annual growth rate we saw in 2020, primarily driven by our commitment to fund R&D to advance our technology and our internal drug discovery pipeline. We also anticipate that software gross margin will be lower than the 81% reported in 2020, reflecting investment to drive and support large-scale adoption by our customers.
We continue to execute on our strategy across our business. Our new collaboration with Zai Lab enables us to more significantly participate in the downstream value of the programs. Our collaboration programs and internal pipeline are progressing. And we are continuing to make scientific advances in our software to drive large-scale utilization, both in drug discovery and material science. And finally, we have the resources to invest in our long-term growth strategy.
I'll now turn the call back over to Ramy.
Ramy Farid - CEO, President & Director
Thanks, Joel. As we pass the halfway point in the year, we are very pleased with the progress we are making across our business. We continue to innovate, and our technology is having a significant impact on our collaborative and internal drug discovery programs. Our internal programs are advancing toward the clinic. Our software customers are increasingly recognizing the benefits of deploying our solutions at scale. And we are growing our team of exceptional scientists and professionals to deliver on our mission of transforming drug discovery and materials design.
At this time, we'd be happy to take your questions. Operator?

(Operator Instructions)
Our first question comes from Michael Yee Jefferies.
Michael Jonathan Yee - Equity Analyst
We wanted to ask around -- the confidence around your guidance and reflecting the confidence in your business, specifically you're maintaining the guidance halfway through the year of $102 million to $110 million for software. But it feels like the low end of that would be a pretty big deceleration not only year-over-year, but also just from the first half of what's going on this year. So 2 parts. One, can you just comment on the lower half of your guidance and why you're maintaining the overall guidance than your confidence in hitting the higher end. And then secondly, if COVID may or may not be picking up, is that actually a headwind or tailwind to your business? Maybe just talk about how COVID, if at all, impacts things.
Ramy Farid - CEO, President & Director
Joel, do you want to take the first part of that question, and I can answer the second one.
Joel Lebowitz - CFO & Executive VP
Sure. Thanks, Mike, for your -- yes, thanks, Ramy. Thanks, Mike, for your question. Sure. So as you mentioned, we're maintaining our overall guidance, and our software guidance as a part of that. And obviously, that annual guidance provides you with our expectations for the back half of the year. So we have pretty good visibility on our business based on the fact that we have very high historical customer renewal rates. But there is some inherent variability in the business, particularly with regards to new customers that we add each quarter as well as decisions from our large customers who might be making commitments for much larger deployment of our solutions in a particular quarter, which, as you know, is a key growth strategy for us.
So some of these decisions actually -- individual decisions can be quite large and can have a pretty significant impact on our particular quarter growth rate. So as we look out to the rest of the year, we think that the guidance that we've provided appropriately captures some of this inherent short-term variability. And we're -- and so that's why we reaffirm the guidance.
Ramy Farid - CEO, President & Director
And with regard to COVID, as we talked about in 2020, I think a lot of software companies did the same thing. There did seem to be some sort of interesting uptakes and renewed interest in computational methods as a result of scientists essentially being locked out of their labs. I'd say at this point, and I think this is what we're hearing from a number of other companies, the sort of accumulation of, of sort of the long-term, absence of travel and face-to-face interactions, I would say, is not helping. It's making it, of course, more challenging to initiate strategic discussions. Not impossible, obviously. But it's more challenging. Again, especially given that it's now been -- I think, 1.5 year -- or 1.5 years or so of essentially zero travel.

Our next question comes from Michael Ryskin with Bank of America.
Michael Leonidovich Ryskin - Associate
Really quick follow-up on what Mike was just asking about. You mentioned sort of strong renewal rates in the software business. Could you give us -- could you quantify that a little bit? How has that trended in the first half of the year? Are you still in the high 90s? Any impact as we sort of lap the comps from last year?
Joel Lebowitz - CFO & Executive VP
Sure. Thanks, Mike, for the question. That's one of our annual key performance indicators, and we don't provide specific guidance. So we're reporting on the mid-year numbers as they can be affected by timing. But what I'd say is that last year, we came in at 99% renewal, and -- of those contracts over $100,000. And over the last 7 years, it's never dipped below 96%. So we're pretty confident in our ability to continue to achieve a very high customer renewal rate.
Michael Leonidovich Ryskin - Associate
Okay. I'll take that. And then on the Zai Lab collaboration you announced recently. You mentioned, first of all, the upfront payment. Could you give us a sense of sort of how sizable -- we saw some details there in terms of the potential milestones, but specifically about the upfront and when it will be recognized? And then sort of bigger picture question on that, should we expect more deals like that? You have a couple of different ways of working with biopharma between the software business, the JVs, the partnerships. And now this is, again, something a little bit new. Is this another avenue we expect you to sort of explore more going forward?
Joel Lebowitz - CFO & Executive VP
Sure. I'll answer the first part, and maybe Ramy might want to add to the third. So with regard to the size of the upfront payment, we didn't disclose that. It is to help us fund some of our research activities. And we are still evaluating the accounting around this deal, but we expect that like many of these types of deals that the upfront payment will be recognized over a period of time. And I think if you think about typical deals where there's upfront payments that we've talked about in the past, that has been the case. And in many cases, it's been over several years.
Ramy Farid - CEO, President & Director
And with regard to, yes, this kind of deal, yes, we're very excited about this kind of deal. We are in discussions with a number of companies around sort of innovative types of deals. This is the kind of thing, as we've sort of talked about before. We're not only innovating in the science. We're definitely, I think, pretty creative in the types of deals we've done, as you can see from the history of the company, going all the way back to Nimbus. And we're very pleased with the nature of those interactions now and certainly expect to do other collaborations in the future.
Operator
Our next question comes from Gary Nachman with BMO Capital Markets.
Gary Jay Nachman - Analyst
First for MALT1, what's involved in the IND-enabling studies? What will be included in the preclinical package that you plan to file next year? And I think you'll be presenting some preclinical data for one of your programs in the second half. In what form do you think that's going to be? And then last one. So it seems like you're looking to expand your platform to other areas in materials like aerospace and electronics. How much of an initiative will you have behind those efforts? And how aggressive will you be finding partnerships in those areas relative to the life sciences that you've been doing more of?
Joel Lebowitz - CFO & Executive VP
Great. Karen, do you want to take the first 2 and I'll cover the last one.
Karen Akinsanya - Executive VP, Chief Biomedical Scientist and Head of Discovery R&D
Yes. Sure. So with respect to the MALT1 program, we will be presenting the IND-enabling package to the FDA, which will include the results of GLP tox study, all of our CMC, support that we've got for our clinical product and really the typical package that you would expect to see going into the FDA to support approval of an IND and initiation of clinical studies. With respect to the science, we've continued to make great progress there. We've characterized our MALT1 inhibitors in a number of different models and have new data with respect to how MALT1 performs, both alone as monotherapy and in combination with other products. As you can imagine, we've been putting together abstracts and sending them out to the regular scientific forums. And so we expect to be able to share some of that in one of those scientific meetings later on this year. So looking forward to that.
Joel Lebowitz - CFO & Executive VP
Yes. And with regard to material science, thanks for asking about that. We're, of course, very, very excited about the progress we're making on that business. increased adoption of the technology by, as you correctly pointed out, by a pretty diverse set of industries. We are -- as we've said before, we aren't leveraging a lot of the existing technology. But as we get deeper and deeper into this field, we are recognizing areas where we can build on the existing technology and develop new advances. And we are absolutely investing in that as a result of the sort of clear interest in computation and quite a number -- again, quite a number of these different fields. So it's a very active area of research.
Again, it's very important to point out, it leverages a lot of the existing technology, and we're building on that.
And then you asked about collaborations. That's absolutely something as we've talked about before, that we're pursuing. We're very pleased with the progress that's being made there with regard to discussions around collaborations, and you should absolutely expect to hear more about that in the future about collaborations following a very similar path that we took with life sciences, a number of years ago, I already mentioned Nimbus, and of course, we've mentioned Morphic. We learned so much from those collaborations. They generated a lot of value. Those were incredibly important for Schrödinger. That's not lost on us, and that's something that we absolutely intend to pursue on the materials science side as well.

Next question comes from David Lebowitz with Morgan Stanley.
David Neil Lebowitz - VP
When you look back at 2020, there was a huge step-up in ACV. I believe 10 companies went to -- went from 10 to companies, 6 company -- or 16 companies for (inaudible) over and ACV. What quarter did -- what quarters did you see the bulk of that shift? And I guess, when do renegotiations with those particular companies, when are they on tap?
Joel Lebowitz - CFO & Executive VP
Sure. I can talk about that. Thanks, David. So I think consistent with what we've been talking about this year, that fourth quarter is expected to be -- provide most of the growth in the second half of the year. A lot just because of the seasonality and calendarization of our business on the software side. We do see a lot of contracts and a lot of large contracts renewing and obviously making decisions on what size to renew at in the fourth quarter. So we see it throughout the year really, but the fourth quarter, there can be a concentration. I'm sorry. And the second part of your question was, again, remind me, please?
David Neil Lebowitz - VP
I guess, following up on that is, when do negotiations for those particular contracts start? Is it something that would start this early? Or does it really come down much closer to the actual renewal date when the discussions occur and...
Ramy Farid - CEO, President & Director
Yes. I can answer -- sorry.
David Neil Lebowitz - VP
Historically, what's the precedents are? Are big purchasers typically more likely to continue being big purchasers?
Ramy Farid - CEO, President & Director
Well, with regard to your question about when the negotiations start, they actually really are -- happened throughout the year. There's constant interactions with the companies throughout the year. We're not just sort of sending the software over the fence and not speaking to them until a few weeks before the renewal. So we're learning about the impact the software is having on the technology, talking to them about new advances. Remember, we have 4 releases a year. So every time there's a release, that's an opportunity to reach out, talk about the new tech -- new products that have come out, new technology, new impacts that we're seeing from the collaborations. And so the discussions are really happening throughout the year, obviously intensify as you get closer to the renewal. So I hope that answers that part of the question. And then I think you asked...
David Neil Lebowitz - VP
Yes. Purchase -- their propensity to -- are they the ones that usually in (inaudible)
Ramy Farid - CEO, President & Director
Well, again, when you see the kind of retention rate that we're having, right, in the very high 90s, there's no right -- That's the answer there, right? If there were -- we wouldn't have that kind of retention rate, if meaningful -- any...
Joel Lebowitz - CFO & Executive VP
And the one thing -- sorry, Ramy, and one thing I can add to that, David, is that we're very pleased that in this quarter that we're seeing the continued momentum and trends that we saw in previous quarters, which is driving the growth on the software side, which is not just the addition of new customers, but also customers increasing the adoption of our solutions. So we've seen that for several quarters as an ongoing trend. And so we think that we can continue in the future in encouraging customers to increase adoption of the solutions at higher levels. Yes.
David Neil Lebowitz - VP
Yes. And one additional question on the drug discovery side, is it possible you could run through the drugs from partners that we could expect to see data from before year-end? And which drugs might actually step into the clinic?
Ramy Farid - CEO, President & Director
I guess we're all thinking about who should answer that. So I think Joel kind of hinted at that. It's very difficult to -- first of all, it's difficult for us to predict when those sorts of events will happen. But it's also because of the nature of the agreements and confidentiality and so on, that's not for us to be presenting. That's really for the collaborators. A number of them have been pretty open about that, I mean one of them is a public company. A number of them have been very open about where their programs are and their plans for the clinic. So I think that's the kind of information that's pretty straightforward to get from the collaborations that we have -- where they have more advanced programs. A number of the other collaborations that we started more recently, of course, are earlier and are still in sort of a stealthy mode. And so it will take a little bit longer, of course, to hear about that. But I hope that's answering the question. If not, please ask it a different -- yes, go ahead.
Operator
Our next question comes from Matt Hewitt with Craig-Hallum.
Matthew Gregory Hewitt - Senior Research Analyst
A couple on utilization, and I've got one regarding the new collaboration. But regarding utilization, can you give us a sense for how many of your customers are coming back multiple times during a year to increase their capacity versus just coming in once a year and adding what they believe they will need for the upcoming year?
Ramy Farid - CEO, President & Director
Sure. Yes, that's a good question. We can't really quantify that. But what we can say is the very, very large majority of deals are annual. There are a few examples of customers that purchased the software in a way that does require upping during the year as the number of compounds that they're running calculations on as they hit the limits that they purchase, but that's unusual. The large, large majority are annual licenses.
Just going back, I think, to the question just before, just -- I'm really sorry to do this. There's just a little bit of information that might be useful to have. We currently have 6 of the collaborative programs that we're involved in are in IND-enabling studies and 4 are in Phase I. Just to give a sense of sort of where those programs. I'm so sorry to do that, but I just wanted to throw that in there. Did you have another question? Or did I answer your...
Matthew Gregory Hewitt - Senior Research Analyst
Yes. Yes, I did. No, then that's fine. Regarding visibility, how much visibility do you have in your current customers' utilization trends? And does that enable you -- given where we're at this point in the year, you know where the customer is at from a utilization perspective, and you can see the growth. Does that really help you from a projection standpoint on what that customer is likely to renew at?
Ramy Farid - CEO, President & Director
No. We do not have insight into their usage. That's something that is closely held to the customers. That's not something that we have the ability to quantitatively look into that. We do, however, of course, know one thing that's important here, which is -- we know how they're capped. Obviously, we know how many licenses they have. We don't know if they're maxing those out, but we know what their maximum is. And we know that in almost every one of our customers, including the largest customers, the maximum number of calculations that can run is still an order to 2 orders of magnitude lower than what our -- what we're using in our collaborations and what we're using internally. And so -- and we can have those sorts of discussions, and we're engaged in those discussions. So even though, again, we don't have access to the exact usage day-to-day, there is that general knowledge. And that's what the nature of the discussions generally are. First of all, pointing that fact out what I just said, and then talking about what's the -- how are we going to get to those higher usage? And often that requires training, expertise, both, by the way, technical -- both on the technical side. So for example, obviously, to be able to run that number of calculations, you need access to a lot of computers, and that has to -- that generally occurs through the cloud, so there's training there and how to use the cloud at this large scale and then obviously deploying the technology from the point of view of the science as well.
Matthew Gregory Hewitt - Senior Research Analyst
That's really helpful. And then I guess one last one for me, shifting gears a little bit. Regarding the collaboration with Zai Lab. Were they an existing customer? Or how did that relationship come about? And as you look at adding more of these types of partnerships, are you typically seeing that these customers are new to the platform? Or are the existing customers saying that we would really appreciate your help and assistance to kind of work through these calculations and this work?
Ramy Farid - CEO, President & Director
Yes. Thinking back at all of the collaborations we've done, either they were with companies that were newly created. So of course, we didn't know, but there was somebody in the -- either in the VC that funded them or one of the founders that knew Schrödinger from a previous interaction. Remember, we're pretty -- we're pretty well-known in the field. And I think it's hard to find somebody who doesn't know who Schrödinger or had some kind of experience with the software either in the current position they're in or from a previous position. That was the case with Zai as well. We've known them for a while. We've known members of the Board. They were -- things like that. And so that's generally how it's -- there isn't usually some sort of surprise or an interaction where there wasn't already some previous sort of interaction with some key person of the company. I hope that's answering the question.

Ladies and gentlemen, this does conclude the Q&A portion of today's conference and also concludes the conference call for today. You may all disconnect, and have a wonderful day.
Ramy Farid - CEO, President & Director
Thank you.
Joel Lebowitz - CFO & Executive VP
Thank you, everybody.
