Good morning and thank you for holding. Welcome to Aon plc's Second Quarter 2021 Conference Call. At this time, all parties will be in a listen-only mode until the question-and-answer portion of today’s call. I would like to remind all parties that this call is being recorded. If anyone has an objection, you may disconnect your line at this time. It is important to note that some of the comments in today’s call may constitute certain statements that are forward-looking in nature as defined by the Private Securities Reform Act of 1995. Such statements are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results or those anticipated. Information concerning risk factors that could cause such differences are described in the press release covering our second quarter 2021 results, as well as having being posted on our website. Now, it is my pleasure to turn the call over to Greg Case, CEO of Aon plc.

Thank you, operator, and good morning, everyone. Welcome to our second quarter conference call. I’m joined virtually by Christa Davies, our CFO; and Eric Andersen, our President. As in previous quarters, we posted a detailed financial presentation on our website. We want to begin by thanking our 50,000 Aon colleagues for their dedication focused on serving clients. Over the last year perhaps certainly every organization around the world has wrestled with how to best support employees, how to manage record volatility and still deliver more value to customers. At Aon, our colleagues have led through all this while also preparing for a substantial integration. What our team has accomplished is extraordinary. Today, we move forward with the benefit of all that work without a constraint of regulatory uncertainty. My remarks will cover our outstanding financial performance in Q2 and year-to-date, provide some observations on the termination of our combination with Willis Towers Watson and speak to our go forward plan to continue delivering great service and innovation on behalf of clients, enabling work for colleagues, and delivering excellent return to shareholders. In Q2 our global team delivered outstanding results across each of our key financial metrics, and I'd note particular strength across the top and bottom line with 11% organic revenue growth driven by mid-single-digit or greater organic revenue growth from every solution line, however with particular strength in commercial risk at 14%, which translated into 17% adjusted EPS growth in Q2 and 13% free cash flow growth for the first half. Our 8% organic revenue growth for the first half reflects mid-single-digit or greater organic revenue growth from four of our five solutions lines. Our Aon United strategy is delivering net new business generation and ongoing strong retention. We also saw double-digit growth overall in the more discretionary portions…

Thanks very much Greg and good morning everyone. We delivered continued progress in both the quarter and year-to-date, including an impressive 11% organic revenue growth in Q2. Through the first half of the year, we translated strong organic revenue growth into double digit operating income, earnings per share and free cash flow growth, demonstrating the power of our Aon United strategy. I’d like to further reflect on our performance through the first half of the year. As Greg noted, organic revenue growth was 11% in the second quarter and 8% year-to-date. We continue to expect mid-single digit or greater organic revenue growth for the full year 2021 and over the long-term. I would also note that total reported revenue was up 16% in Q2 and 12% year-to-date, including the favorable impact from changes in FX rates driven by a weaker U.S. dollar versus most currencies. Our strong revenue growth and ongoing operational discipline contributed to adjusted operating income growth of 11% in Q2 and 14% through the first half of the year. Turning to expenses and margins, there are two key points I wanted to describe further. First, I wanted to speak to the impact of our previously communicated re-patterning of expenses as compared to COVID impact to the spend in 2020, which I’ll describe before any 2021 growth. As we communicated in Q1, the timing of expenses is changing year-over-year, such that a $135 million of expenses moved into Q2 from Q4. This impact is due to the actions we took and highlighted last year as we reduced discretionary expenses to be prepared for the potential impact of COVID-19 and potential macroeconomic distress. The $135 million is approximately 1.5% of our total 2020 expense base. In Q2, this re-patterning negatively impacted margins by approximately 470 basis points, resulting in…

[Operator Instructions] Our first question in the queue is from Elyse Greenspan with Wells Fargo. Your line is now open.

Hi thanks, good morning. My first question is on buybacks. So, you pointed out that you guys typically stronger free cash flow in the second half than the first half. The last year you guys had one and a half turns in the second half free cash flow, and then you alluded to maybe an incremental $1.5 billion of additional debt that you guys could issue. So is that meant to apply that we could see around $3 billion of incremental share repurchase in the back half of this year?

So Elyse we don’t give guidance on share repurchase, but what we can say is, as you mentioned, cash flow in the second half of the year is our seasonally strongest cash flow generating two quarters, Q3 and Q4. We've been very clear that we have the opportunity for additional debt of $1.5 billion in the second half of the year, and therefore we have substantial cash to invest back into the firm whether that organic investment M&A or share repurchase, I would note that we do allocate cash based on return on capital, cash on cash returns, and buyback remains our highest return on capital opportunity. Even at today's prices, it is a fantastic return on capital for shareholders, and on that basis we expect to do substantial repurchases in the second half of the year.

Right, and then my second question, I think you mentioned that folks that were eligible for retention came in with the transaction will be receiving some payments, I think that was the basis for the charges you're going to take in the third quarter, but can you, so I just want to confirm that? And then can you give us a sense of how the employee retention has trended, the past year has been during the pandemic, but why the merger is going on or even over the past couple of months the regulatory review, have retention levels been in line with normal expectations, just can you give us a sense of how things have been trending there?

Sure. So, regarding the $350 million to $400 million of additional charges in Q3, they're really related to the transaction costs, and compensation expenses, as well as a small number of expenses related to further steps in our Aon United operating model. I would say these charges are really related to the cost of terminating though the combination as part of a clean break with Willis Towers Watson. Then in terms of the outstanding work our colleagues have done over the past 16 months, we've taken steps to ensure that our colleagues share in the growth potential of the firm going forward and that includes those who have previously offered retention bonuses in connection with combination. So with that I'll hand to Eric to talk for retention overall at Aon.

Sure, thanks Christa. And I would just say Elyse we continue to attract great people in all the key strategic areas for growth and expertise that Christa outlined in her remarks. We don't really pay too much attention to the headlines or the commentators that talk about talent, and certainly reject the premise of disruption that we've been hearing. Look, we have a great team and I'll just give you a couple of facts. Voluntary attrition continues to be excellent for us. We just did a poll survey in June and ended up with top quartile engagement scores for our colleagues. You know these trends, I think are the result of all the flexibility and connectivity and the support we've been giving to our colleagues over the last six months, not just with the Willis Towers Watson combination, but also with the pandemic. And so we feel really good about the team that we have. The bench, the development of all of our talent, and that we're really well positioned going forward. Maybe the other thing just I would add a thought on top of that, you think about it as a colleague, you're sitting across the table from clients listening to their challenges, their opportunities, where would you want to be? The firm with the capability we have, here and now what we can do, also a greater level of spend and investment and innovation with anyone in the world, and it's just been a great story that's evolved and the pandemic as I have tried to highlight in the opening comments just amplifies the importance of this around the need for innovation, planning, intellectual property, cyber, et cetera. So all these things come together to make the value proposition quite unique, but really I just want to call out our colleagues have been just magnificent over the last 16 months in every way shape or form in terms of how they've not only managed through all the different pieces around integration, but also what they've done for clients, it's just been extraordinary to see and that's showing up in multiple ways.

Okay, thanks for the color.

Next question in the queue is from Suneet Kamath with Citi. You line is now open.

Thanks good morning. I guess for Christa to start, if I think back to your guidance sort of pre-Willis Towers Watson in terms of free cash flow growth, you typically talked about double-digit growth rate. In today's deck, you just talk about free cash flow growth. So I'm just trying to figure out is there something that's different relative to what you've said in the past or do you still think double-digit free cash flow growth over the long term is what you guys are positioned to achieve?

Suneet, we absolutely believe in double-digit free cash flow growth over the long term, and we're incredibly excited about the growth potential in terms of revenues, margins and the free cash flow over the long term, so nothing strange there.

Okay and then, I did note in the second quarter free cash flow was down maybe 13% relative to the second quarter of last year. Is there anything unusual that sort of drove that?

No, nothing. We would say look, you should really look at free cash flow growth over the course of the year, and we will absolutely grow free cash flow during 2021, and I would just say quarter-to-quarter there have been lumpy things. We're very excited about the free cash flow growth year-to-date at 13%.

Okay, makes sense. And I guess maybe bigger picture question for Greg, post this experience with Willis Towers Watson, just want to ask about your thoughts on, you've mentioned transformative M&A in your deck. What are you thinking there in terms of M&A? Should we be expecting things that you do would be on the smaller side, given the past 16 months or just how you're thinking about inorganic growth?

Yes and Suneet, perhaps you come back to what Christa gave out just a bit ago on Elyse's question, we have -- we just got an enormously positive performance, and that's super carried through over the last 16 months that's showing up in what really is the focal point for Aon which is translating revenue into free cash flow and that ability to grow free cash flow. And with that cash really comes how we invest it and it truly comes back to return on invested capital. So we're always going to take steps that actually maximize return on invested capital with the cash on cash return, and we look to opportunities or we have tremendous organic opportunities inorganic opportunities in all shapes and sizes, and very much looking forward to sort of driving shareholder value, applying the cash in the appropriate way and we'll continue to look for all means to do that.

And maybe I might just add and say look, we are incredibly excited about the cash flow growth potential of the firm, both in the second half of the year and going forward. And then obviously our ability to grow debt as EBITDA grows, we've got an enormous amount of cash to invest, and we will invest organically, inorganically with M&A and in buyback on a return on capital basis. And as I mentioned, we've actually got a number of priority areas for reinvestment really focused on meeting on that, it's the clients, addressing the volatility like cyber, helping clients build a resilient workforce, rethinking access to capital and innovative new areas like intellectual property and addressing the underserved through our investments like CoverWallet. So we've got an exciting array of investments that we are continuing to invest in, and so we're really excited about the growth potential going forward.

Okay, thank you.

Next question is from Jimmy Bhullar, with JPMorgan. Your line is now open.

Hi, good morning. So I had a question on just organic growth in the commercial business. And it was obviously 14% for you guys strong for most of your peers as well, and obviously comps were pretty easy, but other than comps what are sort of the main drivers of that? I think you mentioned in your release pricing was a modest positive, but just trying to assess what are some of the things that might not be sustainable because they are related either to a catch up in business activity or other things versus things that might continue at least in the near term?

Certainly, I will be able to start with a couple of new thoughts and Eric, can talk about the different pieces, geographies around the world where we've seen tremendous strength on strength continue to evolve. For us there was really no catch up in any way shape or form. We got back to early last year, we're in a very strong position and that just continued to build through the pandemic. As client need increased, our ability to react to clients and serve them also continued to increase, and so generally we ended up with new business generation. That new business generation really an all time highs and it continued to build, moved into the third and fourth quarter of last year, and now you see it in the first half of this year, and really for the last five quarters are real and through the forced effort on behalf of colleagues around the world on all areas, as they relate to, as related to growth. It's why we underscore and reinforce the mid-single-digit organic for the year and ongoing beyond 2021, but it really is the fundamentals, it really is how we're connecting with clients and supporting clients, how we're applying the Aon United strategy of bringing the best of our firm to clients every day and that actually has just strengthened and grown, until we really come out of the last 18 months, when you think about the chassis of Aon, the Aon United foundation is stronger than ever before. But Eric a lot is going on around the world by geography, a lot of good stories, you got thoughts?

Yes, sure. Listen, I think there's a couple things to point out. One is, we had double digit growth in commercial risk in each of our geographies around the world, so it was really a great quarter all the way around, really strong rollover, really strong retention, which really sets you up in the future for continued growth, and it was a couple things right. The core PNC business performed really well, so really pleased about that everywhere, but also the discretionary work that Greg and Christa had talked about, whether it was transaction liability, cyber, construction other project type work, all of which were performing very well, equally across the world. So we had a really solid performance everywhere and we're really excited about it obviously.

Okay, and then just on pricing, you mentioned a modest positive, what would seem like it would be a better than modest positive just given what we've seen -- been seeing with underwriters, but what are your -- what's the sort of color on that?

Yes, sure. It's always a great question because people always wonder why the direct carrier sort of per unit price doesn't show up and translate across to the intermediaries on the risk side. And listen, I would just say clients, clients make choices when prices move up or down, right and one of the things that we do with them and I think I've mentioned this in the past, we first help them to do identify the risks that they have, and then try and manage them without the use of risk transfer. And then as prices go up, clients finance more of it themselves if they can handle it. And then ultimately when you get to the risk transfer part of where they decide to trade the risk, they make choices there too. The amount of insurance that they buy, the coinsurance, deductibles, things they try and manage. For them the budget that they have to spend on topics like risk transfer. So it's never a direct line from what a carrier publishes as rate to what a client actually does for the risk that they're trying to transfer. And so all those areas that we're talking about, clients have a real heightened focus on during a time when pricing is increasing and they get very specific around how they try and manage it themselves or finance it themselves before they try and risk transfer it into the market.

Are you're seeing more pushback from clients on price hikes, because it seems like commentary from the underwriter side is still pretty positive on what's going on?

So listen, clients certainly don't want after three years of a rising market to pay more for a similar risk, but ultimately I think what they've done is they've continued to just get more sophisticated. I think we've been able to help them with our data and analytics and insight to be able to make better choices around how they handle the risks.

Next question is from Greg Peters with Raymond James. Your line is now open.

Hi, good morning. Thanks for taking my questions. My first question will just stay focused on organic. Beyond commercial risk solutions you had some very strong results in reinsurance and in health. And Greg, I think you did call out a headwind or two in data analytics. Your guidance for mid-single-digit are better going forward. I guess what I'm trying to get at here is how much of the second quarter result was a snap back and how much of it is permanent in terms of how we should think about organic going forward?

Greg, I appreciate the question and the thought, terrific. Listen, as we think about the growth profile, we keep coming back to this idea of the commitment around mid-single-digit or greater for the rest of the -- for the year and for 2022 and beyond. I think about it, we did four to five solution lines and we were meeting that standard in the first half and we got great trajectory. No doubt there's variants that are within the solution lines. I highlighted in data analytic services. Look our travel business is still under a tremendous amount of pressure as you would expect, but still our colleagues are fighting through that, finding opportunities, finding ways to connect with clients and you're seeing that. So for us we feel good about mid-single-digit or greater. We've made that commitment before, and there was really no snap back. As I said before the ability to connect with clients and drive growth has sustained throughout the pandemic and certainly sustained and probably even amplified into 2021. So, that's why we feel quite strong about the outlook.

Got it, and then Christa on the expensive repatterning, as we gradually return back to whatever the new normal looks like, when we and I know you don't like to comment on projections, but when I think about 2022, are we going to have another expense repatterning, if things get back to what the old normal was, or is what you're experiencing here in 2021 sort of the new bar, which we can go to and measure on a quarterly or quarter-over-quarter basis going forward?

So it is the new basis, and we should expect extensively consistent with this pattern going forward. And so really, what I would say is, it's reflecting changes from a COVID impacted 2020 expense base. So 2020 was the unusual pattern and Greg, and 2021 we're repatterning to get back to our normal expense planning. So this is the correct performance across the year going forward.

That is correct. This is Greg. As Christa highlighted very well, when you think about this over the course of a year, and what we're trying to do now within quarters, exceptional performance that continues to improve.

That makes sense. Thanks for your answers.

Next question is from David Motemaden with Evercore ISI. Your line is now open.

Hi, thanks. Good morning. I wanted to stick on cash flow. And I guess first, looks like, I was just wondering, do you think CapEx looked a little bit lower than I had thought? You'd still expect that to be up for the full year? And also, I think when I think about the seasonality, and second half is higher than the first half, I just wanted to confirm that that's excluding the $350 million to $400 million of termination costs and retention bonuses. So we should think, I think that would take away a lot of the seasonality, but just wanted to confirm that?

Yes. So firstly, we expect very strong cash flow in the second half. And yes, it excludes the, we expect the termination expenses to be adjusted out of Q3. Having said that, we do expect free cash flow to be strong for the full year and we're extremely excited, obviously, about the 13% growth in free cash flow year-to -date. In terms of your question around CapEx, we would say that CapEx should increase modestly year-over-year, driven by investments in technology to drive long term growth. And I would say look going forward, we expect free cash flow to grow double digits over the long-term, religion by three key things, growth in operating income, declining uses of cash, and improvements in working capital. And so we're really excited about the growth in free cash flow long-term, as well as our ability to add debt as EBITDA continues to grow. So a substantial amount of cash to invest back in Aon.

Got it, that's helpful. And then maybe just a question, just it definitely sounds this on the Willis merger and any sort of impact that might have on the business. I know you guys spoke about it through, in response to a previous question, but I'm hearing that it sounds like you didn't want the deal to stretch into 2022. And also, obviously there are the retention payments and some of the other termination payments. I guess, could you just maybe elaborate on if you would expect any sort of disruption going forward in the organic growth?

Maybe let's start, it's worth, actually just putting things in context and you think about sort of where we've come over the last 16 months. And we'll translate it directly in the growth, which will be a great story as we shown in the first half. If we take a step back in the last 16 months, the primary thesis behind the combination exceptionally strong. In fact, the pandemic has made it stronger over that period of time. Obviously, strong shareholder approval, regulatory momentum, in virtually every jurisdiction around the world. And I noted obviously, DG comp in the European Theater, and others around the world as well. And just so you understand, we reached an impasse in the U.S. Department of Justice. We could have completed the deal in a couple of ways, but we made the choice to reject what we believe were two unacceptable options. One was the remedies and we could have completed the deal through the remedy, just like we did in Europe. But it wouldn't have been the right answer for us. It simply would not have been the right answer. We roughly know what it would take, but candidly would have damaged our client serving capability as we described before, stifled innovation and as I said, you've heard Eric and Christa talk that we will never, we would never sacrifice our Aon United strategy to close the transaction. This is not going to happen and in the end, that's where we were on the revenue side. And the second option, equally unappealing was litigation. We had an exceptionally strong hand from our view, but the timeline, pushed the deal into 2022. And listen and looked like it did in every way, shape or form, also unacceptable. We're just not going to wait in a holding pattern well into 2022 to sort of have this resolved. It is just too long. So we wanted to make a choice, David, for our firm and well certainly on our terms to move forward independently and obviously, the position of strength, if you think about where we were in 2020, and now where we are now, very much a position of strength. And we're excited about how we move forward with real enthusiasm driven by our team and the strength of our Aon United strategy. So that's the rough picture in terms of sort of where we are, but we have to grow up. Eric or Christa, if you have got some more comments on?

Yes, sure Greg, maybe I'll talk a little bit about the integration planning process and how we're using that work to help propel us forward post this event. Maybe to go back a little bit, we went into the, certainly the pandemic into the Willis Towers Watson combination, in a great place. We were very strong going in, both operationally and with revenue growth. And when we started the integration management effort, we were essentially able to maintain the client momentum and continue to work on our strategy. During the last 16 months of planning, the teams really perfected our Aon operating model, the delivering Aon United Strategy, as well as our go-to-market, how do we actually pull all these teams together for the benefit of our clients. All that's going to be incorporated going forward, which will continue to build the momentum. So, I think while we came into this process in a strong position. I think we're actually coming out of it in an even stronger position.

Completely agree Eric. And I would say, our financial results have strengthened, in growth, in margins, and in free cash flow. If you look at 2021, we delivered 11% growth in Q2 organically, 8% growth organically year-to-date, and 13% growth in free cash flow year-to-date, just stunning financial results in 2021, building on a really strong 2020. 1% growth organically through COVID, 100 basis point margin expansion to 28.5% and 64% growth in free cash flow to $2.6 billion, building on a decade of progress, 4% average organic growth over the last 10 years, 890 basis points in margin expansion over the last 10 years and 15% free cash flow growth each and every year over the last 10 years. So phenomenal set of financial results. So we would say our financial results have strengthened in gross margin and free cash flow. But Greg, do you just want to come back to the growth question?

Yes, so again, David, I just want to give you a sense of sort of what our history has been over the last 16 months to your questions. And then you kind of say, well, how does that translate into growth? I think Eric's point we think was really important. The fundamental capability actually has strengthened. We spent so much time thinking about opportunities on the growth side, on the efficiency side, on the investment side and we came up with a ton of them and we're incorporating all of those. All that then reinforced by, the Aon United strategy and the connectivity and ironically COVID created a situation where we are on WebEx and others have different, different systems, WebEx connected our firm in a way sitting across the virtual table from clients in a way that's been incredibly, incredibly powerful. And that's what's led to literally net new business growth and also growth rates with existing clients, the strongest we've ever seen. So it really puts addition does exceptionally well to continue to increase market share and take share around the world, which we've been doing and continue to do, as well as create net new and at this moment, I don't want to get away. This is not a zero sum game for us. We're winning the zero sum game, but it isn't about that. It's about net new. As we put solutions in place around cyber, intellectual property and climate, I mean, just the three we talked about a lot, and we spend a tremendous amount of time focused on those. So we're very excited about the growth prospects, that's why we talk about an integral digital grader across all our solution lines in 2021 and beyond.

Great, I mean, yes, thanks so much. I really appreciate that color. It’s really helpful. And Aon it's obviously not showing up any sort of disruption. There's no evidence of that in the results, so I definitely appreciate that. Thanks a lot.

Next question is from Meyer Shields with KBW. Your line is now open.

Thanks. I guess my first question is on, how do I put it, communication philosophy. Because it looks like the execution for organic growth for 2021 even single digits are higher, and noticing that this is on a year-over-year basis probably just a phenomenal operating environment with economy, hopefully coming back and sustaining rate increases. And I'm wondering whether the use of the sort of traditional language even it indicates that we shouldn't expect too much from the tailwinds.

Well, Meyer, I wouldn't say that and in fact, what we're trying to highlight is listen, there's still a lot of volatility out there in the world, it's moving around. We essentially have said in the face of that volatility wherever it goes. We're very confident in mid single digit or greater. By the way, not just for this year, but ongoing as a piece and then double digit free cash flow. And our view is that economic model we think about it from an investor standpoint, is extraordinary in terms of sort of what that means. And so this, what we want to do is make sure you understand we're reflecting high confidence in our ability to achieve that. And, Aon will keep pushing forward on that basis. So there's, it's not about rebound or anything else. But Christa anything else you want to say to that?

The only think I would add Meyer is, there is still some macroeconomic uncertainty and there are still some areas of our business like travel events that haven't fully come back. And so, we will navigate through this, and still deliver phenomenal financial results for the year, mid single digit or greater in 2021 and going forward.

Okay, that's very helpful. Second question, I appreciate Eric’s comments on employee retention and attrition. When we look at the on a number of brokers that are out there, in I guess, reinsurance or large accounts, is there any increased competition for talent that would require higher organic growth rates for margin expansion that we've seen in the past?

I would just say overall, it's competitive out there. It's always competitive, as Eric highlighted very well. And then we love the model we have because the opportunity for colleagues at an individual level and literally together and that's really what we're talking about individual capabilities, but also collective greatness, collective ability to succeed is exceptional today. And that's, for us it served us exceptionally well. But there's I wouldn't say Eric could comment on this, a more or less competition and there is always been in terms of sort of what's been out there?

Yes, I agree, Greg. I mean, it's always been a very competitive business across all the risk platforms, whether it's the primary brokerage or the reinsurance brokerage. And so, yes, I think just ultimately we continue to have to bring our best each and every day to our clients with the best tools and insight and if we do that, I think we'll be fine. Christa anything you would add?

Yes, and maybe on the margin point, I guess what I would say is, we can grow margins in any operating environment. You saw last year, when we produced 1% organic revenue growth, we expanded margins. And because of the investments we've made in Aon Business Services, really bringing together all of our operating sort of infrastructure in one place, centers of excellence, all the people and capabilities in one place, we're able to drive productivity benefits each year at scale. And so, we'll continue to drive margin expansion for the foreseeable future, building on the 890 basis points, the margin expansion, we drove for [indiscernible] points a year, over the each year. And so we expect to drive margin expansion in 2021 and each year thereafter, regardless of growth.

Okay, that’s perfect. Thank you so much.

Next question is from Phil Stefano with Deutsche Bank. Your line is now open.

Yes, thanks and good morning. I think that, if I heard you correctly, earlier I think you had talked about a ramp investment that's going to pick up in the near future. I guess, in my mind, the gap of growth and revenues versus underlying expenses is going to narrow. It looked in the long run this normalizes as you've talked about the expectations for margin expansion. So can you just give us a frame to think about how this looks like in the short run, in the extent to which this gap may narrow and maybe some economic sensitivity to the broader recovery?

Yes, so really the point I think I was making Phil was, in Q2 we did see greater underlying margin expansion, excluding the repatterning of expenses, because growth outpaced our ability to invest in that growth and a lot of the investments, what we did invest in people and operations and technologies to drive our business, some of that was not fully incurred in Q2. So it's really a statement about Q2 specifically Phil. And really what I would say is, what you said is exactly right. Over the long-term growth and expenses to drive that growth will be aligned.

Okay, got it. And so, my thought I think, it was perfectly for my follow up. You've talked about deliberate investments in people, technology. Can you give us a little more color on what exactly that means, may be an example or two of what's driving these deliberate investments?

Yes, I mean, there's a number of areas that we're investing. So maybe I'll star and Eric and Greg, you can jump in. But, as an example, we're investing a lot in technology to help deliver innovative data analytic based solutions to our clients to help them manage risk, retirement and health more effectively. So it'd be one area we're investing in, in security, because obviously the security environment and cyber have become a greater threat for colleagues and so, that is another big area of investment. The last is I'd say, we're actually continuing to hire great talent into the firm, but maybe Eric and Greg, do you want to sort of build on this?

Yes, one thing, one real quick, everyone is -- Eric and add some really pointed comments here. When we think about the Aon Business Services, so that platform is of course to describe the technology investment, cyber risk, this is, over the years it would have been very difficult for us to sort of create global impact of our investment, because we couldn't scale it. We can scale it now. So as Christa and the team guided, this investment is incredibly efficient in terms of how we can actually increase capability and make it real around the world. So we don't want to lose that point. It's very, very fundamental to what Aon Business Services is all about. But in addition to that these net new areas that Christa was alluding to are really exciting and this is a net new capability we're bringing in. Some of it is connected to risk, some of it is connected to just fundamental capabilities, certainly on the climate side, intellectual property side, and on cyber side. So a lot we're doing that we are very excited about in terms of the ability to help clients address issues critical to them, that heretofore haven't been addressed in the way that they needed to be, so a lot happening from that standpoint. Eric, and anything else you…?

Yes, you just gave a great overview of it Greg, but if you think about intellectual property and the new skills required there, and if you think about the new risk areas, about renewable energy, about climate modeling capabilities that we need, you mentioned cyber, and certainly in our human capital business, trying to invest in how we do ESG at scale for clients. So there's a whole lot happening on the ground. As Christa said that is supporting the growth that we're seeing, and recognizing that we need to keep investing to make sure we keep growing.

Well, thank you. Good luck.

And the last question that we have in the queue for today is from Brian Meredith with UBS. Your line is now open.

Yes, thanks. So, two quick questions here. First one, just curious Christa, what's the revenue impact of the sale of the retirement exchange? It looks like you're continuing for with that one?

Yes. So the revenue Brian in 2020 for the retire exchange was $176 million? It is predominantly Q4 businesses, you know well.

Great. And then second question, I'm just curious, as a part of this process that you're going on with Willis Towers Watson, you'd obviously identified a lot of cost synergies and expensive potential savings from the transaction. I'm curious if you were able to identify any specifically for Aon if you can see potentially here going forward to help with cost savings and efficiencies as you went through this process?

Brian this, Greg. What we were alluding to and talked about before, I think back and, Eric is going to jump in on this. Eric has led this integration for the last 16 months and this has really been at the one foot level, literally as we engage and connect with our colleagues around the world, and with clients around the world and we've seen and uncovered multiple growth opportunities, investment opportunities, expense opportunities, highly available to Aon specifically and all those are going to be baked in as we move forward. This is back to the theme. We came in the 20th on March 2020 with exceptional capability, strength. And what we've done over the last 16 months around integration is fundamental improvement of our platform. What is going to be the combination combined platform, but it absolutely is applicable to Aon, but Eric, you led this, what do you think?

Yes, Greg, I think there's two buckets, right. I think on the revenue synergies, you're talking about the client value creation model that we've been working on, otherwise are delivering Aon United Strategy, about how you bring the firm together. We're talking about how we're perfecting it. That was done in the context of the integration management planning. But also on the expense side, certainly real estate strategy, technology strategy, all the areas that you would think, having a fresh look with teams that were built specifically to try and challenge the status quo and really pressure test, how can we do it better, how can we do it more efficiently? How do we leverage our Aon Business Services model in a way that we had really started during pre Willis Towers Watson combination to really accelerate how we actually use that capability. I wouldn't necessarily call that last one new. I would just call it expanding what we've been building and really getting it embedded across the firm and across the world.

Terrific, thank you.

Thank you. I would now like to turn the call back over to Greg Case for closing remarks.

Thank you. I just want to say to everyone, thanks very much for being part of the discussion today. We appreciate it and look forward to our discussion next quarter. Thanks very much.

This concludes today’s call. Thank you for your participation. You may disconnect at this time.
