G
Greg Case
CEO and Executive Director

Thanks, Rob, and good morning, everyone. Welcome to our second quarter conference call. I'm joined by Christa Davies, our CFO; and Eric Andersen, our President. As in previous quarters, for your reference, we posted a detailed financial presentation on our website.

We're pleased to report that our global team delivered another strong quarter, performance, results and momentum. And we begin the call today by thanking our colleagues for everything they do to help our clients address immediate and long-term demands around the risk and people. United delivered by our colleagues, gives us the ability to meet this demand and balance across our portfolio. capitalizing on innovation and momentum and investing to meet demand. This ensures we win more, retain more and do more with our clients. There is now almost universal agreement to client demand to address risk and human capital has never been greater. For example, our catastrophe insight report estimated global economic losses for natural disasters in the first half of 2023 and were $194 billion, notably above the 21st century average of $128 billion and fifth highest on record.

Even more profound, in addition to economic costs, we know these disasters have tragic human costs that reinforces the high value and building resiliency and protection in advance of disaster. To this end, we recently announced the placement of the Parametric insurance program for the government of Puerto Rico. It's the single largest program of its kind that the U.S. Commonwealth has ever placed. This program was designed by our reinsurance and commercial risk teams. And in the event of a sizable earthquake or hurricane, Puerto Rico will quickly receive liquidity and enabling its government to focus on rapid recovery and reconstruction.

This placement was the result of Aon's data, analytics and capabilities from across our firm, cemented by our deep understanding of public entity demand, risk capital and reinsurance markets and really, really great work by our team.

Turning to financial performance. In the second quarter, we delivered strong organic revenue growth across our solution line, including 10% growth in health solutions and 9% growth in reinsurance solutions contributing to 6% overall organic growth in the quarter and 7% in the first half. In health solutions and a revenue growth of 10% on top of 11% last year was driven by strength in the core. Our team has done terrific work, helping clients navigate the demands of their talent agendas balancing optimal benefits for their people with inflationary cost pressures while also taking steps to deliver on their people strategy at a time when bringing total rewards, health and wealth benefits together is human capital are more important than ever.

In reinsurance solutions, our team delivered another very strong quarter at 9% organic growth on top of 9% last year. Driven by strong net new business generation, our teams continue to help clients navigate a challenging and complex market and are already preparing data, analytics and insight as we help our clients understand and address ongoing volatility and capital considerations. We're also seeing capital come into the market, particularly in cat bonds as our team has placed over $5 billion across 21 deals year-to-date. In wealth solutions, we delivered 2% organic growth driven by ongoing trends in demand we've seen in project work around market volatility and regulatory changes, as well as the ongoing trend of pension derisking, which we expect to continue in the quarters coming ahead, given the market conditions.

We continue to see opportunity to help clients react and prepare for regulatory changes, and market volatility with our data analytics and expertise. And finally, commercial risk solutions delivered 5% organic growth in the quarter. Globally, we saw strong growth across most major geographies with double-digit growth in Asia and the Pacific. In the U.S., we saw strength in core retail brokerage, including from property, casualty, and construction. As we've communicated previously, results were pressured by the impact of external M&A and IPO markets on M&A services, a headwind we now expect to continue in the back half of the year, given ongoing external conditions.

Overall, in the quarter, our strong performance was driven by the strength of our Aon United strategy and Al Business Services platform. In Q2, we translated 6% organic revenue growth into 110 basis points of operating margin expansion. Net of ongoing investment in the business for long-term growth. These results contributed to first half financial performance of 7% organic revenue growth and 90 basis points of adjusted operating margin expansion. And we remain very well positioned to maintain this momentum and to deliver on our ongoing financial guidance of mid-single-digit or greater organic revenue growth margin expansion and double-digit free cash flow growth for 2023 and the long term. This financial performance is ultimately the product of our ability to address client needs to Aon United. And this strength is foundational in supporting our ability to evolve in response to changing client demand, fully demonstrated by our move to risk capital and human capital.

This focus is bringing our 4 solution lines more closely together to better address client needs and is already yielding meaningful client impact. Take human capital. Our clients are changing how they're thinking about their colleagues. We're facing an increasingly complex external environment with pressures around cost, growth, remote and hybrid work and workforce composition. On their own internal environment, their people strategies are increasingly complex, considering traditional total rewards and health benefits and newer additions around future skills and well-being. Our connectivity and across health, wealth and talent, enables us to bring data, analytics and solutions to address this need. In one great example, our team developed a diagnostic tool for clients that produces a human sustainability index, or HSI this tool combines individual and team assessments with peer data and analytics-based benchmarking to enable our clients to directly connect people strategy goals to execution.

The measurable results encompassing 8 wellness pathways such as physical, emotional and financial aspects, supports individuals and teams to assess exactly what's working and for whom, along key metrics, so our clients can adjust or change their tactics to drive their people strategy and ultimately, their bottom line. In many respects, this work represents bringing next level data science into talent development and leadership. Ultimately, the HSI solution identifies gaps and what our clients offer to their people, encompassing health, wealth, rewards, and other wellness programs, and it provides a trackable plan to strengthen the company's talent strategy on their most significant often external commitments at a time when these commitments are more important than ever.

In summary, our strong performance is a direct result of our ability to help clients better understand their challenges and opportunities and to take actions to protect their business and improve their performance. Further, our recently announced enhanced focus on risk capital and human capital is already driving benefits and strengthening this capability. Our strong year-to-date financial results, including 7% organic revenue growth and 90 basis points of margin expansion, on the direct outcome of the strategy and position us very well to continue delivering in 2023 and over the long term.

Now I'd like to turn the call over to Christa for her thoughts on our financial results and long-term outlook for continued shareholder value creation. Christa?

C
Christa Davies
Executive VP and CFO

Thanks so much, Greg, and good morning, everyone. As Greg highlighted, we continued delivering on our key financial metrics, both in the quarter and year-to-date. Through the first half, we translated 7% organic revenue growth into 90 basis points of adjusted operating margin expansion. These results position us very well to continue to drive results in 2023 and over the long term, and we look forward to building on this momentum.

As I reflect on our performance through the first half of the year, as Greg noted, organic revenue growth was 6% in Q2 and 7% year-to-date. We continue to expect mid-single-digit or greater organic revenue growth for the full year 2023 and over the long term. I would also note that reported revenue growth of 7% in Q2 and 6% year-to-date -- sorry, 6% in Q2, 7% in Q2 and 6% year-to-date, includes an unfavorable impact from changes in FX of 1% for Q2 and 2% year-to-date, primarily driven by a strong dollar versus most currencies.

I'd also highlight fiduciary investment income, which is not included in organic revenue growth, with $64 million in Q2 and $116 million year-to-date or 2% of total revenue in both periods.

Moving to operating performance. We delivered strong operational improvement with adjusted operating margins of 33.6% in the first half, an increase of 90 basis points driven by revenue growth and efficiencies from May on business services, overcoming expense growth, including investments in colleagues and technology to drive long-term growth.

Looking forward, we expect to deliver sustainable margin expansion in 2023 and over the long term as we continue our track record of cost discipline and managing investments in long-term growth on an ROIC basis. As we've said previously, Aon Business Services remains one of our key drivers of margin improvement, and this operating model has now reached an inflection point. In response to client demand and the opportunity, we're evolving to an organization that drives efficiency, operating leverage and margin expansion to one that's also increasingly driving improved client service delivery and accelerating innovation at scale. This evolution of Aon Business Services requires investment in three areas, which we expect to manage in line with our ongoing financial guidance and like we do for all investments in long-term growth, on a disciplined ROIC basis.

First, standardized platforms. We're digitizing and connecting existing platforms and creating an ecosystem that encompasses technology and operations that brings our data, analytics and expertise together for our clients and our colleagues. Second, standardized operations. Across our solution lines, there are places where we have common processes. We see opportunity to continue to bring operations and expertise together across our firm, to support clients across all solution lines, bringing people and process together, drive further efficiency enables us to scale best practices. Third, new products at scale. We see significant opportunity to deliver new data-driven products, which we can then effectively develop and scale. The work we've done to standardize platforms and operations enable us to rapidly develop, deliver and scale innovative solutions across the portfolio. In response to client demand and to deliver content and capability to all clients both from organic or inorganic investments.

Even more importantly, operating Aon Business Services as one organization with disciplined prioritization and governance around initiatives ensures we can move quickly on opportunities that create value for our clients and colleagues, such as the one we see on AI.

Just as a few examples. We see real opportunity here to enhance colleague productivity by leveraging the services of our technology partners in a protected environment to enhance existing offerings like our human capital assistance by building an AI risk framework for our clients. And finally, to create complementary data sets to enhance our risk analytics like the catastrophe modeling. We translated strong adjusted operating income growth into adjusted EPS growth of 5% in Q2 and 6% year-to-date.

As noted in our earnings materials, FX translation was an unfavorable impact of approximately $0.05 in the quarter and $0.19 per share year-to-date. If currency is to remain stable at today's rates, we would expect no impact in the third quarter and a favorable impact of $0.05 per share in the fourth quarter for an unfavorable impact of $0.14 per share for full year 2023. I'd also note, other nonoperating expense had a $0.25 per share or 10% unfavorable impact in Q2, and a $0.44 per share or 6% unfavorable impact year-to-date. This reflects an unfavorable impact from increase in noncash net periodic pension expense, as well as a gain on sale of businesses in the prior year period and balance sheet FX remeasurement in the current period.

Turning to free cash flow and capital allocation. Cash from operations was flat year-over-year and free cash flow decreased 7% to $986 million, primarily driven by a $77 million increase in CapEx. As we've communicated before, free cash flow can be lumpy quarter-to-quarter and free cash flow generation in the second half of the year is seasonally stronger than the first half. We continue to expect to deliver double-digit free cash flow growth for the full year. CapEx was elevated in the first half of the year compared to the prior year period as we initiated a number of projects with spend heavily weighted in the first half across technology to drive long-term growth like the investments we're making to evolve Aon Business Services. I'd note CapEx can be lumpy quarter-to-quarter.

We expect CapEx to moderate in the back half of the year and now expect an investment of $220 million to $250 million in CapEx in 2023. As we've said before, we manage CapEx like all of our investments on a disciplined ROIC basis. Our outlook for free cash flow growth in 2023 and beyond remains strong, and we continue to expect to deliver double-digit free cash flow growth for the full year and over the long term, driven by operating income growth and working capital improvement. Given our strong outlook for free cash flow growth in 2023 and beyond, we expect share repurchase to continue to remain our highest return on capital opportunity for capital allocation. We believe we're significantly undervalued in the market today highlighted by approximately $1.1 billion of share repurchase year-to-date.

We also expect to continue to invest organically and inorganically in content and capability that we can scale to address unmet client need. Our M&A pipeline continues to be focused on our highest priority areas that will bring scalable solutions to our clients growing and evolving challenges. We will continue to actively manage the portfolio and assess all capital allocation decisions on an ROIC basis.

Now turning to our balance sheet and debt capacity. We remain confident in the strength of our balance sheet and manage liquidity risk through a well-laddered debt maturity profile. As we've said before, we expect to add incremental debt as EBITDA growth over the long term while maintaining a strong investment-grade credit profile. I'd note our term debt is all fixed rate with an average weighted interest rate of approximately 4% and an average weighted maturity of approximately 11 years.

In summary, our strong financial results for the quarter and year-to-date reflects strong operational performance driven by our Aon United strategy and our Aon Business Services platform. We expect to continue to make progress on our key financial metrics and our commitment to drive long-term shareholder value creation. With that, I'll turn the call back over to the operator, and we'd be delighted to take your questions.

Operator

[Operator Instructions] And our first question comes from the line of Charlie Lederer with Citi.

C
Charlie Lederer
Citi

You mentioned continued headwinds in M&A services in the back half of this year in your prepared remarks. When should we think about that dynamic lapping? And is it more of a pricing issue? Or can you comment on what's driving that?

G
Greg Case
CEO and Executive Director

I really appreciate the question, Charlie. Just start overall, just commercial fundamentals generally. Obviously, that's part of the real question. very strong retention, very strong new business exceptional, a lot of strength around geographies around and core P&C. It really is this 1 area in M&A services, which is a particular strength of ours. But as you know, deals -- yield count and volume was down 30% to 40%. We expect that in the first half of the year, we expect to see it in the second half of the year. As that comes back, we will come back with an absolute vent just given our overall position.

But Eric, anything else you'd add to that?

E
Eric Andersen
President

Yes, Greg, I would just say that while the deal volume is down, as you're saying, we have been spending time with the team expanding the potential client base. The historic nature of the product has been driven more towards private equity-type buyers. But we've been spending time working with the corporate clients, making sure they're aware of the capabilities and how those products and services get used. So that when the market does come back, and it will come back, we'll be situated to lead that market as we do today.

C
Christa Davies
Executive VP and CFO

And Charlie, I would just say that while we've lapped the downturn, we do expect the pressure to continue in the second half as the external outlook has continued to be soft.

C
Charlie Lederer
Citi

And then I'm wondering if you can comment on the momentum in your IP business, intellectual properties. How meaningful is that to organic revenue growth? And there have been some articles in the press about it recently. So just trying to understand how you see that business affecting second half results, if at all?

G
Greg Case
CEO and Executive Director

Love this question, Charlie. Really appreciate you raising it. We love this business. It is a phenomenal opportunity for us. If you think about intellectual property overall, this is just hugely significant. This is representative -- we talked before, 85% of the value of the S&P 500, which really tied back to intangible assets. And if you go back to 2016, we started with an amazing investment, bringing in 601West to Aon, it's 20, 25 colleagues. We've now invested in hundreds of colleagues with a truly unique market-leading platform to really help understand this opportunity and these risks and the value of these assets.

And we built a marketplace with so many insurers 26, almost 30 insurers sort of in the marketplace $2 billion in aggregate insured transaction value. And by the way, demand is stronger than ever. And we're evolving in the market, and there are always so many different third parties out in the marketplace and different things that affect that. But we love the position. We love the progress we've made, and we feel stronger than ever about the future opportunity.

Eric, anything else you'd add?

E
Eric Andersen
President

Yes, maybe two things, Greg. One, as a percent of revenue, it's still -- the market is still in its infancy. So I wouldn't overly rotate on it other than the potential that we see down the road. And to your other question, about some of the activity in the market. Obviously, we're not going to comment on specific third parties.

But I would say, as part of our fundamental role of matching risk to capital, we work with many of parties that bring capital to the marketplace. Some of them use let us a credit to backstop the capital, used by the third parties. But it does provide the kind of capital and that we need that the clients need to deploy to gain reinsurance capital that they're looking for. So it's just one of the ways that we match risk of capital together on behalf of our clients.

Operator

Our next question is from the line of Mike Zaremski with BMO Capital Markets. Please proceed with your question.

M
Mike Zaremski
BMO Capital Markets

I guess back to the organic growth environment. Just curious, you mentioned some headwinds on the M&A side. There's probably some tailwinds, too, which we can see. But would you say you were clear to about 5% or greater is still the outlook. But would you say growth is kind of thinking back to the back half of the year is kind of steady or accelerating or decelerating? Or any trends you'd like to point out in any of your businesses in terms of momentum or tailwinds other than the M&A call out that we should be considering into the back half of the year?

G
Greg Case
CEO and Executive Director

Yes. Literally, Mike, I love this question. If you step back and think about sort of the growth platform and how it's evolved. First, just for context, we put -- we think about growth and really all the benchmark objectives over the course of the year. So if you think about it, for us, growth is organic revenue and growth is, by the way, margin improvement, and growth is absolutely the translation into free cash flow.

And we would say, if you think about just performance in Q2 and really the first half, it's really reinforced our confidence and you see momentum around meaning our full year 2023 objective. So this is mid-single digit or greater across the board, look at the strengths in health, which were exceptional for the first half, and certainly for the quarter in reinsurance and other areas, too, even in commercial risk with the headwind that we just highlighted. So very strong on the solution line side.

And then you also saw exceptional movement on margin expansion. When you think about the growth here to 110 basis points for the Q and 90 basis points for the first half. And most importantly, you heard Christa reemphasize double-digit free cash flow growth for the year. So for us, we see this trend continuing to turn where we are. And there's a lot that goes behind that. Maybe, Eric, additional context around that foundation or what's driving that?

E
Eric Andersen
President

Sure, Greg. And you mentioned 2 of them in your written remarks around the Parametric that we did for Puerto Rico as well as the Human Sustainability Index. Those are just 2 examples of the Aon United teams working together. But I think I would also say that the client demand is evolving, and it's getting more complicated, I think as the world gets more complicated.

And so our strategy of evolving to risk capital and human capital, I think, uniquely positions us to take advantage of that capital to drive growth -- I'm sorry, take advance of that situation to drive growth. And when I think about it, just to put a little clarity on it, from a risk capital standpoint, I think it gives us a couple of things. It gives us access to global capital no matter what form. So insurance, reinsurance, ILS parametrics to help clients transfer the risk that they want to transfer, and also create more dynamic markets. And I think it also helps us to create and deliver the analytics that have historically driven our reinsurance business over to the large corporate clients who have a more acute need today, to understand their risk from property exposure, to climate change, as well as the cyber liability exposures.

And it also gives our leaders client leaders and brokers, the best insight of the market dynamics. So that's on the risk capital side.

On the human capital side, bringing health, wealth and talent together is effectively meeting clients where they are today. Clients are looking for a holistic view for their employee relationships, both from hiring, training, health wellness all the way through to retirement. And we're seeing that. We're really excited to see that strong growth in our core health and benefit business globally. Winning new clients, expanding the relationship with them across all aspects of that employee life cycle is gratifying and exciting. So we see a lot of opportunity with both risk capital and human capital, both in our strong core but also as we develop sort of new capabilities.

But Christa, anything you could add to that?

C
Christa Davies
Executive VP and CFO

Well, I mean, Mike, you also did just ask about second half outlook. And we would say year-to-date growth was 7%. We do think about our results over the course of the full year. And we are on track for our full year guidance, mid-single-digit or greater organic revenue growth, margin expansion and double-digit free cash flow growth.

And so we're really excited about the momentum in the first half and that continuing into the second half. And I think just each quarter, we have different seasonality of revenue, but we really do think about it over the course of a full year. And so mid-single-digit or greater organic revenue growth for the full year.

M
Mike Zaremski
BMO Capital Markets

And my quick follow-up is curious on the expense efficiency side, a number of competitors have kind of talked about leaning in to be able to kind of find more ways to be efficient over the last, I guess, in this post-pandemic world and there's different nuances to each company's strategy, but it feels like some of them are taking off of the and United Playbook, which you guys were a first mover on. Just curious, is there anything you want to call out in terms of -- do you see incrementally more opportunities today for expense efficiencies or nothing really to call out that's getting you guys even more excited about kind of some margin levers in the coming year.

C
Christa Davies
Executive VP and CFO

Look, we do actually, Mike. So thank you for the question. Look, we are on the next evolution of Aon Business Services. And as I mentioned in my opening remarks, expanding from just driving efficiency to really improve customer service delivery, and innovation at scale, helping us accelerate growth. And so as we think about margins, we think about margins again over the course of the full year, sustainably and over the long term.

And year-to-date, we saw 90 basis points of margin expansion, and offset by investments in the business including people and in our technology. In particular, you saw an increased investment in IT, 13% year-to-date. And the majority of this is around our core business platforms to help clients and support revenue growth. And you saw CapEx up as well, again, driving long-term margin expansion through the continued investments around standardized operations, standardized platforms, and innovation at scale, which we are really excited about in Aon Business services.

E
Eric Andersen
President

Yes, one comment on it because we -- I know the question was on efficiency, but the ability to leverage the analytics that we have inside of ABS helped us develop the human Sustainability Index, helped us create the insight that we're able to bring to corporate clients. As they think about managing their climate exposure from a property standpoint, how all of that comes together is part of the ABS strategy and how we execute it. So while there is efficiency, there is great opportunity, I think, to drive new products, new solutions and better solutions that our larger clients are looking for us to help them.

G
Greg Case
CEO and Executive Director

And just to remind you, Mike, we brought in -- we've been working on this since 2017, actually prior to that by 2017. We have literally with the leadership under Christa, our new COO and others brought an India tremendous amount of capability to bear. And now we're on kind of the next wave, building on a very, very strong platform that we pulled together.

So it's -- for us, we're very excited about this. for both the efficiency reasons that Christa described very well and the effectiveness outcomes that Eric described. And that really is the muscle and the foundation of Aon Business Services. Very excited about it.

Operator

Our next question comes from the line of Weston Bloomer with UBS. Please proceed with your question.

W
Weston Bloomer
UBS

My first question is on comp and benefits. It looks like that picked up pretty meaningfully over the last 5 quarter trend and you highlighted investments in colleagues and there's a pretty high competition for talent. Can you maybe comment on the pace of hiring you're seeing more broadly? And was there maybe a pickup in retention based comp in the quarter? Would be curious on maybe attrition rates and commercial risk and reinsurance as well.

C
Christa Davies
Executive VP and CFO

And so maybe I'll start with sort of the math of just -- if you think about this, and again, we look at the sort of over a full year. But if you just did year-to-date, you'd see organic revenue growth of 7% year-to-date. Comp and ben is up 4% year-to-date. And so there's lumpiness in every quarter. And so what we would say is we feel good about that.

And in terms of attrition, we would note that attrition in 2023 is below 2019 or below pre-pandemic levels. And so we feel really good about where attrition is across the board. And we also would note that engagement levels are at the highest they've ever been in the firm's history. And so we feel really good about the talent we're attracting.

But Eric, you may want to jump in here just in terms of the talent side.

E
Eric Andersen
President

Yes, sure, Christa. And I always think that the industry spends a lot of time reading the headlines on some of the industry rags about people move here and there. And I think it gets over rotated as Christa, you shared some of the great steps. I will say we are making some pretty significant talent investments in our core health and benefit business, in our strategy and technology group inside of reinsurance.

Some of our key geographies where we're seeing great growth opportunities. So a lot of great things happening there, Christa, and you shared the metrics of engagement and attrition and things like that. But I would -- one last comment I would make on it, is on our risk capital and human capital platforms it actually allows us to increase the flexibility of where we deploy talent to opportunities. So being able to take reinsurance analytics and help a commercial client think about analytics like an insurance company does, I think, gives us a real competitive advantage. But other than that, we continue to invest pretty heavily in our talent, and we would expect to do so to come in the future.

W
Weston Bloomer
UBS

And then my second question is on wealth solutions organic. I know you had highlighted difficult comp on performance fees in the quarter. I was wondering if you could maybe quantify that impact? And then is wealth solutions a business where you could see mid-single-digit organic growth over the next year, maybe more in line with the rest of Aon. That growth had been lower single digits over the past few years. So curious if we're seeing maybe momentum there.

E
Eric Andersen
President

Maybe I'll take that one, Greg. Look, I think the wealth solutions business is a great business for us, and we do see growth opportunities over the mid and long term. If you think about the pieces of it, the retirement piece, which is the pension actuarial work, continues to be a solid business for us. There's a whether it's in the pension derisking that Christa mentioned or whether it's just regulatory changes that drive activity.

The U.K., EMEA, very solid this quarter. And then there's the investment management business. The advisory business continued to be pretty strong. The delegated part of it continues to have some impact from the AUM movement from -- in U.K. and North America that we talked about last time. But overall, really bullish on the business and expect that it will hit mid-single digits for us as we go down the road.

Operator

Our next questions are from the line of Bob Huang with Morgan Stanley. Please proceed with your question.

B
Bob Huang
Morgan Stanley

I know that you talked quite a bit about tech innovation and efficiency. Maybe if I can just dig a little bit deeper on the cost of AI implementation, right? Obviously, tremendous potential down the road, but from what we've seen recently, for example, Microsoft just announced that their AI-enabled products are twice as expensive as non AI-enabled products. Just going down that line of thinking, can you maybe help us think about how your AI investments fits in -- the cost of that fits into your three areas of investing with the AR business right now?

C
Christa Davies
Executive VP and CFO

Yes. Look, thank you so much for the question, Bob. And we are super excited about AI more broadly and how it can apply to our business. And we would say we think about this in terms of everything from really basic machine learning, robotic process automation, all that stuff that helps us drive automation and efficiency at the sort of very low end, very cheap and super scalable, and we're really looking to implement that broadly across our business, to help our colleagues get out of the sort of day-to-day cutting and pasting and inefficient processes that they're doing today and equally to make things much easier for clients to interact with us and do business. And so that's sort of the low end.

And then you could say at the high end, sort of generative AI, it's really helping us drive insight and impact in the analytical areas that Eric was describing around risk capital and human capital. Catastrophe modeling, helping us add data sets, the human capital assistant, helping clients interact with human capital assistants, much like they would an expert in human capital today. And so Bob, we're very thoughtful about the cost of this, and where it's best to use basic technology, machine learning, robotic process automation, because it's just cheaper and more efficient and more scalable broadly. And where we're really trying to have insight and impact with clients and use generative AI. So we're sort of scaling it depending on the impact and opportunity.

G
Greg Case
CEO and Executive Director

And I just had two observations, on this. First, we've been doing AI, as Christa described, really for a decade. So it's not as we haven't been incorporating this. It's one of the reasons we drove an business services. That's my second observation. Because we have Aon Business Services, because we've been working on it since 2017, we actually have a platform to scale these ideas. Absent Aon Business Services, literally, the ability to kind of get this moved around 120 countries around the world is basically 0. So you can come up with a good idea in a geography, but how do you actually systematically move it around the world. So one of the reasons we're excited about our ability to do this and do it cost effectively is Aon Business Services.

B
Bob Huang

My second question, maybe just to go back to the line of questioning regarding Commercial Risk Solutions, right? And obviously, you've talked in depth about why the U.S. segment is the way it is. But you also -- one of the things we noticed is that Asia has been strong for a few quarters.

In the last quarter, you also saw strength in Latin America and rest of the world. Just as we gradually come back to a more normal M&A market in the U.S., how durable is the growth in the rest of the world. I'm just trying to think down to next year, how we should think about Commercial Risk Solutions growth going forward?

G
Greg Case
CEO and Executive Director

Listen, we -- as we've described, we feel very good about the progress back to kind of the overall Aon United strategy, the core fundamentals as you highlighted well geographically very strong. Even in North America, retention very good, new business is very good. Core P&C exceptional. We just have a wonderful strong business, our capability in an area of M&A services, which, by the way, we're feeling now, but we embrace completely because as the market comes back, as Eric described, we benefit from that as well.

But the fundamentals, the track is everything we've described around literally winning more clients and been doing more with them, and keeping them longer for all the reasons that we talked about around our overall and strategy. So we're feeling very, very good about trajectory and momentum, recognizing there are market conditions out there, but good about that overall.

Eric, what else would you add to that perspective?

E
Eric Andersen
President

Yes. Maybe the only other angle I would say, Greg, is the sophistication of the products that are entering into places like Asia-Pacific and Latin America continue to evolve as the clients evolve. So whether it's risk financing techniques, whether a specialty products, whether it's the international as those organizations expand outside their home countries. So as those economies continue to develop, whether it's India, whether it's other parts of Asia, we're able to grow with them and help them as they need more sophisticated products. So we are very excited about the platforms that we have in Latin America and Asia-Pacific, and we do see good growth opportunities over the long term.

G
Greg Case
CEO and Executive Director

One other point on that, Bob, just to sort of make it. I was in Singapore with Christa a month ago, opening our global climate hub, phenomenal. And we had the opportunity to go around and see so many different clients in that perspective. It really reflected exactly what Eric is describing. Their needs becoming more global and more interconnected. They want to see global Aon put it in their backyard.

That was a very, very positive sort of overall kind of finding as such as we're standing and thinking about that. It really does bode well to what the opportunities are. And then if you take that in some of Eric's other comments around risk capital and what it really means, bringing reinsurance analytics into the commercial space in an effective way, also something that was very, very positive. So just a specific example in a region, as you highlighted, where we have a particular opportunity. The same is true in Latin America.

Our next question comes from the line of Rob Cox with Goldman Sachs. Please proceed with your question.

R
Rob Cox
Goldman Sachs

So in reinsurance solutions, really strong results obviously, but I would have thought you would see more acceleration or a sequential acceleration given the Aon Benfield exposure to property cat in the U.S. Can you provide some color there? And then -- also on the prospects for growth in the back half of the year in reinsurance, as we've seen some news articles regarding kind of an above-average chunk of the facultative business being hired by a competitor.

E
Eric Andersen
President

Sure. Greg, let me take that one. So on the first half, listen, we are really proud, excited whatever word we can use on our reinsurance capabilities, really great first half, great second quarter, a great first half coming off of a couple of great years. Just remember that most of the treaty business happens in the first half, and so a lot of that is now finished. But I would say that as clients have been dealing with the changing reinsurance market, they've made their own decisions. Sometimes they don't buy certain layers, sometimes they buy less, sometimes they buy differently.

And so that's always a decision that we help our clients make as they think through how they want to use reinsurance capital for their business. It does, by the way, explain a little bit of what's going on in the primary market around property, as more of the risk is now sitting on the primary insurers they are now dealing with how do they price it and what kind of risk do they take. So it is an interconnected system of reinsurance and insurance.

So just to point that out. And I think on the second half, tends to be more around the ILS business and facultative business. And I do think we had a very strong first half, in fact. And our expectation is that should continue as the primary clients now may have less low-level reinsurance protection on property catastrophe or secondary perils like wildfires or hailstorms or what have you. And so the ability for the insurers to manage that exposure, the tool that they would use now is facultative reinsurance on an individual risk basis.

And the last point I'll make, and Greg, maybe I'll throw it to you is facultative reinsurance is also being used on things like captives or large corporates where they're also repaying more of the risk themselves. So don't just think about it as a reinsurance tool. You should also start to think about it as large corporates that are trying to access, not just traditional insurance markets, but also reinsurance markets. But in fact, is the way they do that.

But Greg, maybe anything you'd add on that?

G
Greg Case
CEO and Executive Director

You summarized it very well. I would just add a couple of things on the talent point overall and in reinsurance. Look, reinsurance, our colleagues, this has been strength to strength, really over the last 5 years. It's been a tortious. It's also one of the areas we've invested heavily and continued content and capability, not just core reinsurance, but if you think about what we're doing in cat bonds and ILS, we lead the world in this, the work we've done in strategy and technology group Eric described before, this is just substantial investment.

And with this core in reinsurance, we now have this incorporated into the overall risk capital effort. And so it's really, for us, we're very -- we're excited about the possibilities and the capability we have to help clients, and it continues to build, which is why we feel so strongly positive about the second half of the year and the ongoing results here.

R
Rob Cox
Goldman Sachs

And maybe moving back to commercial risk. If we exclude these external factors on the M&A services business, is it fair to assume that the remainder of the business accelerated sequentially, kind of along with the accelerated renewal premium change that we saw in the market this quarter?

C
Christa Davies
Executive VP and CFO

I mean, Rob, we're not giving specific guidance on commercial risk at that level? What we would say is we're extremely excited about year-to-date growth of 7% overall for AON. And on track to mid-single-digit or greater organic revenue growth for the full year. And obviously, we've had a real headwind in this M&A area given transaction volume, as Greg described, is down 30% to 40%, and we expect that softness to continue into the second half of the year.

R
Rob Cox
Goldman Sachs

And maybe just one last question on health solutions. Really strong growth. Just you guys pointed to the growth outside of the United States being particularly strong. And I'm just curious what's driving that? Is that market share gains, medical inflation? Any color you could provide there?

E
Eric Andersen
President

So I would say more of market share gains and the ability of the team to work together globally through global benefits. Remember the health systems are different everywhere in the world. So -- when you look at the U.S. system versus the U.K. versus Europe or anywhere in Asia-Pacific or LatAm, they're very different.

But the needs are often of one organization expanding globally. They need that expertise. And so our global team really well connected, working together to able to help global clients as well as local clients. So we think it's market share gains in the local countries and really excited about what they've been doing over the course of the last year or two.

Our next question is from the line of Elyse Greenspan with Wells Fargo. Please proceed with your question.

Elyse Greenspan
Wells Fargo

My first question, Christa, I think last quarter, you had pointed to CapEx of around $200 million to $225 million for the year. I just want to confirm that, that's still your kind of best estimate there. And so with the improvement in free cash flow in the back half, I guess it's going to come from a combination of lower CapEx and just growth in operating cash flow.

C
Christa Davies
Executive VP and CFO

Elyse, we actually have increased our CapEx guidance to be $220 million to $250 million for 2023 and that's really driven by the investments we're making across Aon Business Services platforms and applications. to drive future growth. And so we're really excited about that. The improvement in free cash flow and the double-digit free cash flow growth for the year is going to be driven by operating income growth and working capital. And I did note that second half free cash flow growth is always significantly stronger than first half.

Elyse Greenspan
Wells Fargo

And then my second question, going back to commercial risk, I recognize right that you guys do have a good market share within the M&A business, right, that has slowed. But you will have easier comps in the back half of the year. even recognizing that there'll be some headwinds from just still low M&A volume. Wouldn't you expect sequentially commercial risk to show better growth in the back half relative to the first half of the year?

C
Christa Davies
Executive VP and CFO

Elyse, I'll try and do this again because I probably didn't explain this well the first time. What we -- we are lapping the comps that's absolutely right. But what we're seeing in the external market is continued pressure into the second half of the year in the M&A environment. So we expect that trend to continue.

Elyse Greenspan
Wells Fargo

And then in reinsurance solutions, Greg, I think you highlighted just kind of robust cap on activity you guys have seen. How do you -- what are you seeing on the capital side within the reinsurance market and thoughts just for the potential opportunities over the rest of the year and then also into 2024.

G
Greg Case
CEO and Executive Director

Listen, overall, Elyse, and Eric to comment on this, for sure. Look, there's still pressure here. There continues to be pressure on the capital side, we're incredibly vigilant about finding options, matching capital risk in terms of what we do for our clients every day. We're navigating through it. You're seeing movement on the ILS side.

We talked about $5 billion we've done in 21 deals year-to-date, which has been phenomenal. So we see an opportunity there. But it's still constrained. There's still pressure.

Eric, what else are you add to that?

E
Eric Andersen
President

Yes. Look, Greg, I would say I'll do the ILS side first is -- ultimately, we're seeing investors that have historically invested in cat bombs, either allocate more to it, so they see opportunity. Investors that had walked away from the area have sort of returned as well as new. So you're seeing some expanded sort of market opportunity, which is why I think that market has been so dynamic in the first 6 months.

I think on the overall capital provision of the reinsurance market, you're starting to see an equilibrium. You're seeing the big players get more active, who see opportunities, especially on the property cat side. And so -- and you're seeing investors look to participate in support, either through their funds or other ways, not necessarily in new company creation, which is sort of what would normally happen in the cycle but more in support of existing players who are already leaders in the industry. So we're getting to an equilibrium around pricing of property cat.

Certainly, as you go into the 1/1 renewals in 5 months, there'll be talk of inflation, there'll be talk of what happens over the hurricane season in the summer and other events. But I do think that as the market has moved, it has found an equilibrium in property cat as well as on the casualty side of the business.

Next question is coming from the line of David Motemaden with Evercore ISI. Please proceed with your question.

D
David Motemaden
Evercore ISI

Just had a follow-up question on commercial risk. You guys spoke about this a couple of quarters ago, I believe it was the fourth quarter, you said the capital markets activity had a 5-point drag on the organic growth in commercial risk. Could you size how much of a drag that had on organic growth in commercial risk this quarter?

C
Christa Davies
Executive VP and CFO

So we have not disclosed that detail. We did, as you mentioned, disclosed it in Q4 and we haven't disclosed it going forward. What I can say is we're the leader in the space, and we're incredibly excited about our capabilities, as Greg and Eric have described. and this having a real impact on our business. But we're continuing to invest in it because we know as M&A volume comes back, this business is incredibly well positioned to do fantastically well.

G
Greg Case
CEO and Executive Director

And David, we continue to reinforce literally the exact guidance we had before. And as we think about where we were, they look greater for the year overall for the business, even in the face of this challenge that Christa described.

D
David Motemaden
Evercore ISI

And also just to clarify, so tough comps in this business in the second half of '22 -- or I guess the comps are definitely easier. I think second half of '22 is very depressed. So -- is it that you guys -- you guys aren't expecting it to be down again off of that depressed base, but it's more just you don't see a recovery off of that depressed base? Is that the right way to put it?

G
Greg Case
CEO and Executive Director

It's literally as simple as you almost listen to the investment bank calls. We can talk to the CEOs of those divisions. As that activity comes back, we are incredibly well positioned, not just in the core areas we've done before, but also with the broader commercial applications, as Eric described before. So we've just gotten stronger. Literally as the transactions come back and the volume comes back, we're there. And so you can predict as well as anyone. All we're trying to do is be clear.

D
David Motemaden
Evercore ISI

And then just on the continued investment in tech and talent, and it also sounds like even with the increased outlook on CapEx for the year, it's going to tick down in the back half of the year. And I'm just trying to just compare that to the continued investment in talent that it sounds like you guys are making. Should I take that to mean that more of the expenses are going to be coming through OpEx, instead of running through CapEx and then there could be a little bit more of a headwind to margin improvement in the second half.

C
Christa Davies
Executive VP and CFO

So what we really said was we've given guidance on CapEx, $220 million to $250 million. Yes, you're absolutely right. CapEx is a little slight loaded with how the projects worked out this year. But we do think about it over the course of a full year, CapEx, $220 million to $250 million for 2023. In terms of margin expansion, we expect full year margin expansion. We are on track for mid-single-digit organic -- mid-single digit or greater organic revenue growth, margin expansion for the full year and double-digit free cash flow growth.

And so yes, things are pattening slightly more in the first half in terms of some expense growth and CapEx growth. But really, you should think about these things over the course of the full year.

The next question is from the line of Meyer Shields with KBW. Please proceed with your question.

M
Meyer Shields
KBW

I guess we're all digesting just how significant the M&A practice is in terms of revenues. I hoping you could give us some guidance on sort of how to think about the margin impact, whether it's what you've seen in recent quarters, or what that implies for margin expansion when this business line recovers?

C
Christa Davies
Executive VP and CFO

Yes. So thank you so much, Mark. What I would tell you is we are on track for full year margin expansion. And the margin in this business we continue to manage the business as an overall portfolio. And I would say they're not particularly different to the rest of the business. We are focused on continuing to invest our entire portfolio in higher-revenue growth, higher-margin areas supported by -- and as a services with the analytical impact.

And what I would say is, as you think about margin expansion long term, it's really just another way to measure the value we create for clients, which is why our data analytics and insight matter so much because that's increasingly what drives value as our clients look to understand forward-looking risk. And so it's those areas of the business that generate more value for clients. And then obviously, with Aon Business Services, we're driving to create that value more efficiently, which is why we're really investing in Aon Business Services to get it to the next level around driving operational excellence, better customer service and increased innovation at scale. And so we're really confident about driving sustainable margin expansion in 2023 and each year beyond that.

M
Meyer Shields
KBW

Second question, I know you typically don't disclose expected tax rates and unless you want to change the approach now. I was hoping you could let us know, given OECD minimum tax reform, internally, so you -- are you expecting the tax rate to go up?

C
Christa Davies
Executive VP and CFO

So Meyer, as you exactly predicted, we are not giving guidance on the tax rate going forward. As I look back historically, exclusive of the impact of discrete items, which can be positive or negative, and historic underlying rate over the last 5 years was 18%. So we feel really good about our overall global capital structure, our global cash structure and our ability to navigate regulation and legislative changes going forward.

Operator

Our last question is from the line of Jimmy Bhullar with JPMorgan. Please proceed with your question.

J
Jimmy Bhullar
JPMorgan

So first, I just had a question for Christa on how you think about the impact of inflation on your results? Obviously, it helps on the revenue side. But to the extent there's competition for talent or higher IT expenses than it hurts on margins. But assuming inflation stays high, is that a positive for you overall? Or is it a negative or a push?

C
Christa Davies
Executive VP and CFO

So what we would say is inflation overall is good for our business. And what we've seen so far is the inflationary impact on our expense base. You saw compensation impacted in '21, '22 and again in the first half of '23. We've seen that come through on the expense base.

What we're starting to see come through is inflation impacts on the revenue side, whether that's increased asset values or whether that's medical and health care inflation. So it's impacting commercial risk and health insurance prices and therefore, our revenue lines. And we expect that impact on inflation to come through in our revenue over the next 12 to 24 months. And so we would expect that positive side of inflation to start coming through.

But Eric, anything else you'd add here on inflation?

E
Eric Andersen
President

Yes. Listen, I think how asset values are repriced. I think that is something that's been sort of re-put into the business in a more consistent way, especially on the property side. I think inflation around verdicts on the liability side. So I think it is that you're saying, impacting pricing from an insurer standpoint.

I would say it also creates sort of decision-making that the client will make. So the clients may take higher retentions, they may use captives that requires different support. It may -- they may take things on their own balance sheet versus transferring it. So it's not a straight line and often, it will turn into other capabilities that we can provide clients service for, rather than just straight up insurance pricing. So the clients are reacting to inflation the way any business would. And so that gives us an opportunity to provide a broader suite of capabilities to them as they're managing it.

J
Jimmy Bhullar
JPMorgan

And then on share buybacks, the last few years, they've been heavier in the second half than in the first half. Should we assume a similar pattern this time and especially considering that your free cash flow is going to be higher as well? Or does the buyback activity thus far this year already incorporate the higher free cash flow in the second half?

C
Christa Davies
Executive VP and CFO

Yes. So Jimmy, what we would tell you is we think about allocating cash based on return on capital, cash on cash return and our highest return on capital opportunity remains share repurchase. And so as we generate cash, you can think about us allocating it disproportionately to buy back. Because it sets the bar for all other uses of cash.

And look, what we would say is we don't actually forecast buyback by quarter. But you can see in any calendar year, it's the highest use of cash across the firm. And so whether that cash is coming from debt or operating cash flow, as we generate that cash, we'll utilize it to buyback or M&A or organic investment, depending on the ROIC return. And we definitely see a huge opportunity to invest in buyback given we are substantially undervalued today, based on the way we value our business on a DCF basis.

Operator
