Operator

Good morning, and thank you for holding. Welcome to Aon plc's first-quarter 2023 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 also 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 first-quarter 2023 results, as well as having been posted on our website.

Now, it's my pleasure to turn the call over to Greg Case, CEO of Aon plc.

Greg Case -- Chief Executive Officer

Thanks very much, and good morning, everyone. Welcome to our first-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.

Before we begin, as always, we want to thank our colleagues for the great work they are doing every day around the world to help our clients and each other. We continue to live in a world where volatility, complexity, and uncertainty are increasing. And in this environment, our clients are being asked to make decisions faster than ever. And as a result, we see strong and ongoing demand for our advice and solutions as many of our clients realize that remaining in defensive or reactive mode is not sufficient.

And in fact, a pivot to offense is ultimately necessary to win and achieve their objectives. Clients are telling us there are two primary areas where they're urgently looking for a competitive advantage, risk and people. Addressing these challenges requires that we bring the best from across our firm to enable our clients to make better decisions, which is the core of Aon United. Given these ongoing demand, our strategy positions Aon as uniquely capable of helping clients go on offense and make better decisions that mitigate risk to their business and maximize the impact and engagement of their people.

Take ESG or environmental, social, and governance, as an example. These are major, interconnected categories that cut across traditional silos. Our clients need a broad, strategic view to understand and assess all the risks around ESG and any targeted solutions and capabilities to solve for these risks. Our recently published ESG impact report describes our work helping clients address these issues, as well as the impact across our firm.

And we're delighted to report on our own progress against long-standing commitments in these essential areas. First, on environmental. We're making progress toward our goal of net-zero emissions by 2030 and have reduced our overall Scope 1, 2, and 3 emissions footprint by 16% from our 2019 baseline and by 4% in 2022, enabled by efforts like smart working and supplier centralization through Aon business services. On social and specifically around our colleagues, Aon United is not just a strategy.

It's our culture, and it reflects our commitment to inclusion, diversity, and the well-being of our colleagues. This year, we're continuing to embed IND principles and practices and to hold ourselves accountable with increased transparency and oversight at all levels of the organization, starting at the top with our board of directors. On diversity, for example, we reported progress in 2022 and the percentage of female people managers and U.S. ethnically and racially diverse managers.

In 2022, we also enhanced focus on learning, development, engagement, and well-being because we know that supporting our colleagues is not only the right thing to do for them, but it also ensures we retain, grow, and develop the best talent to continue to support our clients. And finally, on governance. We've highlighted board review of top ESG and climate-related risks and actions from our ESG steering committee, as well as steps on cybersecurity and privacy, all aligned with our long-standing overall enterprise risk management strategy. While we're proud to report on these steps in our report, there is still work to do, and at the same time, we're even more excited about the work we're doing to help clients, as many risks connected to progress on ESG align with our core businesses.

On the people side, for example, we continue to develop new solutions while bringing together existing capabilities across different markets and geographies to address specific needs. One recent client facing significant organizational change realized many of our employees were unsure and unclear about titles, career ladders, compensation mechanics. And at the same time, this client needed to reduce cost, increase efficiency and simplicity, which they knew would drive engagement. To address, we brought expertise from around the firm.

Our commercial risk team brought deep understanding of this client strategy and desired culture. Our Aon business services platform served as a powerful example of how we could help them simplify their operations and reduce costs. Finally, our health and human capital teams brought a series of solutions, including optimization of global benefits and a skills taxonomy strategy to increase employee alignment and engagement. And while the solution leverages many existing offerings, the real innovation is bringing these pieces together along with our Aon business services team, who provided insight and change management expertise around moving to a business services model, an essential piece of the puzzle for our client.

The result, our client is driving increased engagement with a clear, more effective benefit structure and talent strategy and outsourcing capabilities that will help drive simplicity and efficiency, all enabled by our teams coming together as Aon United. And we see examples like this across the firm every day as we help our clients manage risk and support their people. They demonstrate the opportunity we have to continue delivering innovative solutions at scale to address our clients' unmet needs at a time when doing so has never been more important. Turning to financial performance.

In the first quarter, we delivered very strong organic revenue growth across our solution lines, with 9% growth in reinsurance, 8% growth in health solutions, and 6% growth in both wealth solutions and commercial risk solutions. In reinsurance, our teams were exceptional in guiding our clients to the 1/1 renewal environment. demonstrating the strength of our team's advice, data-driven analytics, modeling, and execution capabilities. In health solutions, we saw strength in core H and B and ensuing capital in a seasonally larger quarter for European health renewal, as our teams help clients navigate the ongoing challenging environment for their people, encompassing employee health, rewards, engagement, and well-being. In wealth solutions, our team delivered another very strong performance with 6% growth, driven by ongoing trends around regulatory changes like GMP equalization, pension risk transfer, and the levering impacts of the fixed-income market volatility as our teams help clients reassess and potentially adjust their strategies.

We would note that after two very strong quarters, Q2 '23 will be impacted by performance fees in the prior year period. And finally, commercial risk solutions grew 6% in the quarter, with strength in Europe and the U.K. in their seasonally largest quarter. Overall, we observed the property market remains an area of increasing challenge and volatility.

Market dynamics are causing reinsurers to shift risk appetites, requiring primary areas to accept more risk, which in turn means property placements are even more challenging for our clients. In this environment, our strength in analytics and the ability to respond to clients' need for cover in a capital-agnostic way, bringing capability across reinsurance and commercial risk, is essential. Our capabilities enable us to assess an analyze integrated broking options, including traditional risk placements, wholesale, MGAs, facultative, captives, and insurance–linked securities. By helping clients assess options across capital sources, we ensure they are able to optimize their own total cost of risk and risk appetite.

For example, one client came to us looking to consolidate to a single-property and terrorism program across 11 asset classes with over 80 billion in property values. Our team came together seamlessly across geographies and specialties, the developer program that leverage traditional carriers around the world and a captive, successfully completing the program and driving significant cost savings for our clients, all enabled by the work we've done to break down barriers within our firm through Aon United. Overall, in the quarter, we're pleased with performance of the strength of our Aon United strategy and Aon business services platform, translated 7% organic revenue growth into 70 basis points of operating margin expansion, net of ongoing investment in the business for long-term growth. In this period of ongoing external volatility and increasingly interconnected risk, the opportunity for us to help clients is greater than ever, position us very well to continue driving results in 2023 and over the long term.

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

Christa Davies -- Chief Financial Officer

Thanks so much, Greg, and good morning, everyone. As Greg highlighted, we delivered strong operational performance in the first quarter, highlighted by 7% organic revenue growth that translated into 70 basis points of adjusted margin expansion. This is a strong start to the year, and we're very well positioned to continue driving results in 2023 and over the long term. As I reflect on the quarter, as Greg noted, organic revenue growth was 7%, driven by ongoing strong retention and net new business generation.

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 5% includes an unfavorable impact from changes in FX with 3%, driven primarily by a weaker euro versus the U.S. dollar, as Q1 is our seasonally largest quarter for euro-denominated revenues. I'd also highlight fiduciary investment income, which is not included in our organic revenue growth, was $52 million or 1.4%.

Moving to operating performance. We delivered strong operational improvement with adjusted operating margins of 38.7%, an increase of 70 basis points, driven by organic revenue growth and efficiencies of Aon business services, overcoming expense growth, including some investments in colleagues and technology to drive long-term growth, and some ongoing resumption of T&E, especially compared to the prior-year period when business travel was still suppressed by COVID-19. Looking forward, we expect to deliver 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 previously communicated, we think about margins over the course of a full year, driven by three areas. The first is top-line revenue growth.

The second is portfolio mix shift to higher-margin businesses as we invest disproportionately in areas of increasingly client demand, supported by data-driven solutions. And the third area is increased operating leverage from ongoing productivity improvements from our Aon business services platform. I'd highlight, Aon business services continues to be a key contributor to margin expansion and represents a competitive advantage, especially in an inflationary market. Our Aon business services platform continues to drive efficiency gains, improve quality and service, and increase innovation at scale.

And related to Aon business services, I'd like to highlight the essential role of Aon business services in enabling our climate net-zero goals. As a professional services firm, the biggest part of our own emissions is from our supply chain. Through the Aon business services organization, 90% of the spend is managed through preferred channels, which enables us to drive efficiency and also deploy decarbonization strategies. As Greg said, this resulted in a 4% reduction in emissions last year, while also allowing us to increase supply diversity utilization to 6% of our addressable U.S.

spend in support of our goals around inclusion and diversity, both meaningful accomplishments that are enabled by our Aon United strategy. Organic growth and margin expansion translated into adjusted EPS growth of 7%. As noted in our earnings material, FX translation was an unfavorable impact of approximately $0.14 per share. If currency should remain stable at today's rates, we would expect an unfavorable impact of approximately $0.04 per share in the second quarter and $0.14 per share for the full-year 2023.

I'd also note other expense had a $0.19 per share unfavorable impact in the quarter, including a $0.05 per share unfavorable impact from an increase in noncash, net periodic pension costs in line with what we communicated previously, as well as an unfavorable impact from a gain on sale of business in the prior-year period and balance sheet FX remeasurement in the current period. We expect the $0.05 per share unfavorable impact from increased net periodic pension costs to continue for each quarter this year, and we currently expect gains from divestitures to be immaterial for the full year. Turning to free cash flow and capital allocation. I'd note Q1 has historically been our seasonally smallest quarter from a cash flow standpoint, due primarily to incentive compensation payments.

And as we've communicated before, free cash flow can be lumpy from quarter to quarter. Free cash flow decreased 17% to 367 million, primarily driven by higher cash tax payments and a $53 million increase in capex. Capex was elevated in the first quarter compared to the prior-year period as we initiated a number of projects with spend heavily weighted in Q1 across technology to drive long-term growth and real estate aligned with our smart working strategy. I'd note, capex can be lumpy quarter to quarter, and we expect an investment of 200 million to 225 million to 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 double-digit free cash flow growth for the full year and over the long term, driven by operating income growth and working capital improvements. Given our strong outlook for free cash flow growth in 2023 and beyond, we expect share repurchase to continue to remain our highest ROIC opportunity for capital allocation. We believe we're significantly undervalued in the market today, highlighted by approximately 550 million of share repurchase in the quarter.

We also expect to continue to invest organically and inorganically in content and capabilities that we can scale to address unmet client needs. Our M&A pipeline continues to be focused on our 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. Turning now 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. In Q1, we issued 750 million of 10-year senior notes, consistent with our past practice, and expectation to add incremental debt as EBITDA grows over the long term, while maintaining our current investment-grade credit ratings. Factoring in this issuance, I'd note that our term debt is all fixed rate with a weighted average interest rate of approximately 4% and a weighted average maturity of approximately 11 years. Our first-quarter results reflect strong operational performance, driven by our Aon United strategy.

We start the year in a position of strength and 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.

Questions & Answers:

Operator

Thank you. At this time, we'll be conducting a question-and-answer session. [Operator instructions] Our first question comes from the line of Jimmy Bhullar with JPMorgan. Please proceed with your question.

Jimmy Bhullar -- JPMorgan Chase and Company -- Analyst

Hey, good morning. So, first, I just had a question on your expectations for the tax rate for 2023. It was high. I think it was around 19.5% in the first quarter.

That's higher than the 17% to 18% range you've had the last few years. But what drove that? And what are your expectations for the tax rate for this year?

Christa Davies -- Chief Financial Officer

Thanks so much for the question, Jimmy. As you know, we don't give guidance on the tax rate going forward. But if I look back historically, exclusive of the impact of discrete items, which can be positive or negative in any quarter, our historical underlying rate has been 18% for the last five years.

Jimmy Bhullar -- JPMorgan Chase and Company -- Analyst

And then, the changes in Singapore and a few other places, should those have a material impact? Or is there any reason to expect the rate to be different this year than in the past?

Christa Davies -- Chief Financial Officer

Jimmy, we feel really confident about our overall capital structure for the company. We're domiciled in Ireland. We run a global capital pool, and we run a global cash pulling structure. And that gives us enormous flexibility as we think about any future legislation.

Jimmy Bhullar -- JPMorgan Chase and Company -- Analyst

OK. And then, just lastly on fiduciary investment income, assuming rates stay where they are, is there further ramp-up in that that you'd expect as like your portfolio sort of resets to where rates have gone? Or has the full impact of the rise in rates over the past several quarters, is it already reflected in your numbers?

Christa Davies -- Chief Financial Officer

Yes. So, what we would say is, as we roll through, we really saw the pickup in fiduciary investment income in Q3 last year. So, you'll see the upside in Q2 and then, less as we move through the rest of the year. I would note, as you think about our overall fiduciary balances, we have, on average, 6.5 billion of fiduciary investment -- of fiduciary assets.

And every 100-basis-point increase in the short end of the interest rate curve is $65 million, top line and bottom line. You should think about those fiduciary assets, Jimmy, as split roughly 50-50 between the U.S. and international.

Jimmy Bhullar -- JPMorgan Chase and Company -- Analyst

OK. Thank you.

Operator

Thank you. Our next question comes from the line of Andrew Kligerman with Credit Suisse. Please proceed with your question.

Andrew Kligerman -- Credit Suisse -- Analyst

Hey, good morning. You mentioned in the release that the U.S. grew modestly in terms of organic revenue growth in commercial risk solutions. And transaction and M&A was probably with a very tough comp.

So, it looks like as we get into the second quarter and the rest of the year, that's really not a tough comp anymore. Could you give any sense of what that impact was in the quarter? And should we expect going into the next three quarters that we could see a significant contribution to organic growth?

Greg Case -- Chief Executive Officer

So, first of all, Andrew, thanks very much for the question. We appreciate it. We would observe, by the way, across the board, as you think about sort of growth for the quarter, it's been a strong quarter for us, 6% organic across all the solution lines. I think it may be the first time we've accomplished that in a long time, and it's really been terrific.

On the U.S. side, it's an exceptionally strong business. You highlighted a great very, very strong comp last year and then just very, very strong capability in the specialty areas that a few of which have been under pressure. But we continue to invest in them because we know they're going to be terrific long term.

So, for us, listen, continued momentum across the board. And as the market shifts a bit on the M&A and transaction side, we're going to obviously benefit from that. Eric, anything else you'd add?

Eric Andersen -- President

No, Greg, I think you covered it well. I think it's still foundationally very strong. The work that we're doing for our clients today on the commercial risk side with all that's happening in the market, whether it's risk analytics, captives, the broad suite of capabilities we can help them with as they're navigating the market dynamics, are still very strong. And so, pretty positive on it.

Andrew Kligerman -- Credit Suisse -- Analyst

So, basically -- just tell me if I'm interpreting it right. With all these amazing things you're doing, you had a pretty big drag from transaction M&A., that goes away, we could see potentially an even better organic growth quarter next quarter?

Eric Andersen -- President

I would say the first quarter last year was a very strong quarter for commercial risk. The transaction solutions business, I think, as Greg said, great capability subject to, obviously, some outside market dynamics that -- but we feel really strongly about that team. And when that comes back, certainly holding that skill set for us is such a great value driver for clients that we're excited about it.

Andrew Kligerman -- Credit Suisse -- Analyst

Got it. OK. And then, Christa mentioned about 200 million to 225 million of capex expenditure targeted for this year. You're doing so many interesting things with ABS and other technologies.

Anything stand out that you're investing in right now that will drive future growth?

Christa Davies -- Chief Financial Officer

I mean, the capex that I mentioned, the 200 million to 225 million, Andrew, I would say, is primarily focused on IT investments to drive long-term growth. So, whether that's scale investments in our platforms to help clients innovate or whether that's in security and infrastructure to keep our clients better protected and the firm better protected, and so we're investing a lot in our Aon business services platform, better connectivity, better data analytics, better insight. And it's really helping our clients deliver great value to our -- our colleagues deliver great value to our clients.

Andrew Kligerman -- Credit Suisse -- Analyst

Got it. Great. And then, just last quickly, M&A pipeline and any areas of interest right now? Should we expect anything as the year progresses?

Christa Davies -- Chief Financial Officer

Yes. Thanks for the question. We have a fantastic M&A pipeline, and it is focused on our highest growth, highest margin, highest return on capital opportunities. And it reflects the areas we continue to invest in, areas of content and capability that we can scale across the firm.

In areas like data analytics, you saw us do Tyche and ERN last year in that data analytic intensive area, areas like health and wellness and human capital, areas like our core risk offerings and helping our clients be able to model and manage risk better. And so, we've got lots of areas of great opportunity around the globe, and we're really excited about it.

Andrew Kligerman -- Credit Suisse -- Analyst

Awesome. Thank you.

Operator

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

Robert Cox -- Goldman Sachs -- Analyst

Hey, thanks for taking my question. Curious if there's any way you can help us quantify or help better understand the impact that higher T&E and inflation is having on the expense base?

Christa Davies -- Chief Financial Officer

So, what I would tell you is, if you look at that other general expense, which is up 20%, that is primarily driven by T&E. And the thing I would note is you're comparing it against Q1 2022, which was an unusually low year in terms of -- usually a low quarter in terms of T&E because of COVID.

Robert Cox -- Goldman Sachs -- Analyst

OK. Got it. And is there anything to sort of look into -- I noticed in the presentation that you added -- that the margin expansion for this year is net of investment in long-term growth. Is that more of just calling out that the things you guys are doing in terms of investing? Or is there something to look into that?

Christa Davies -- Chief Financial Officer

It's exactly the same as always. So, what we would say is we grow margins each and every year. And our margin expansion for the last 12 years has been 1,120 basis points or approximately 90 basis points a year. And that 90 basis points a year over the last 12 years has been a gross margin expansion higher than that, and then it nets to 90 basis points, net of the investments we're making in long-term growth.

So, that is consistent with the way we drive margins each and every year.

Robert Cox -- Goldman Sachs -- Analyst

OK. Perfect. And then, maybe just shifting to the wealth segment, very strong and above-average growth in wealth for a second straight quarter kind of despite some headwinds in the investment business. Curious how long you expect these tailwinds could play out? Is it quarters? Is it a year? How long should we be thinking about that?

Greg Case -- Chief Executive Officer

Listen, as you highlight, Robert, teams have done a terrific job in really over multiple years. We look at the last two quarters, the overall performance exceptional, really reflecting a lot of what's going on in the world out there. The regulatory changes we highlighted around GMP and others, pension risk transfer, and they were just uniquely well positioned to sort of address that. So, that's really what's driving the demand from the client standpoint, and the team has done a terrific job.

We did highlight in the opening comments, listen, the comp for next quarter is going to be particularly challenging in terms of sort of where we are. But fundamentals, exceptionally strong, and the wealth has done a terrific job. Eric, what else would you add to that?

Eric Andersen -- President

Yeah. The minor point I would say, Greg, is that it's a global answer. We're seeing growth in the U.K., in particular, especially around the guaranteed minimum pension piece, but also in North America and in Europe. And so, the retirement side of wealth has been very strong for us and really like -- and you called out the investment consulting, investment advisory business.

So, the challenges there will lap eventually, but you've described it right.

Robert Cox -- Goldman Sachs -- Analyst

OK. Thanks for the color.

Operator

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

Weston Bloomer -- UBS -- Analyst

Hi. Thanks. Good morning. My first question, I noticed real estate costs were up year over year for the first time, I guess, since 2021.

Is that primarily just a function of the investments you're making in smart working? And just given the investments in capex that you've made, is it fair to assume that that should continue to grow year over year throughout the course of 2023?

Christa Davies -- Chief Financial Officer

Yes. So, the real estate is up 4%. It's reflecting back to office, in fact, reflecting the investments we made in smart working, as you said. Last year was impacted by FX.

But look, I would put this in the context, Weston, of we're going to grow margins each and every year. And as I mentioned, that margin expansion over the last 12 years has been 90 basis points a year. And that margin expansion reflects a gross margin expansion much higher than 90 basis points, offset by investments in the business. And then, again, on the capex point, we've guided to capex for the full year of 200 million to 225 million for the full year.

That includes the capex investments in IT, in long-term growth and in real estate, in our smart working initiatives. And you should expect capex to grow each and every year in line with overall expense growth.

Weston Bloomer -- UBS -- Analyst

Great. Thank you. And a follow-up on the wealth performance fees. You highlighted a 2Q headwind there.

Is there an associated headwind in the back half of the year as well? Or is it just isolated to the second quarter? And is there a margin impact from that as well?

Christa Davies -- Chief Financial Officer

It is just a Q2 impact. And no, there's not an associated margin impact.

Weston Bloomer -- UBS -- Analyst

Great. Thank you.

Operator

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

Elyse Greenspan -- Wells Fargo Securities -- Analyst

Hi. Thanks. Good morning. My first question, I guess, goes back to tying together some of the prior discussion on margins, right? So, Christa, you guys -- you mentioned the historical 90 basis points of margin expansion that Aon has seen over the past 12 years.

So, I'm just trying to understand why we shouldn't expect that level, so the 90 basis points, in addition to the benefit that you guys are getting from fiduciary investment income, which I calculate was around 80 basis points this quarter? Or are you choosing to reinvest more in the business because of the strong tailwind we have from higher fiduciary investment income?

Christa Davies -- Chief Financial Officer

Thanks so much for the question, Elyse. And look, we do think about margins over the course of each year. And as you said, we've driven 1,120 basis points over the last 12 years or 90 basis points a year. And that 90 basis points a year is reflecting a gross margin expansion much higher, net of investments we make in the business each and every year.

And we do -- we did see in Q1, 70 basis points of margin expansion, with 80 basis points of favorable impact from fiduciary investment income, Elyse, just as you said, offset by investments in the business, including in our people, technology, and an ongoing headwind from resumption of T&E, all of which we manage in a disciplined way based on ROIC. And we think about margins balancing a number of factors, revenue growth, underlying expense growth, investment in our team, T&E, and then the puts and takes around fiduciary investment income and FX. And we look at them all together and over the course of a full year and expect to drive margin expansion over the full-quarter 2023.

Elyse Greenspan -- Wells Fargo Securities -- Analyst

Thanks. And then, my second question on reinsurance, right, 9% organic in the quarter. That was stable with the fourth quarter, but I might have thought that just with the really strong rates that we saw during the January 1 renewals that that growth might have picked up sequentially. Can you just give us a little bit of a -- just some of the trends that you saw in the reinsurance business that impacted that 9% in the quarter and how we should think about the balance of the year?

Greg Case -- Chief Executive Officer

Eric, we'll go to you with one disclaimer here. I just want to highlight, if you think about what our reinsurance colleagues have done over the last number of years, it's really been extraordinary and, at least, they have really driven the level of performance with clients around the globe in a very unique platform that's been terrific. And remember, again, our efforts aren't -- are connected to rate but not tied to rate. We're helping clients understand, measure, and mitigate risk, which means we're shifting programs, doing things that are unique, flexing the muscle around analytics to help them make better decisions.

So, what we want to see is client growth, which we have seen, top-line growth, which we've seen, and translate into real impact, which we've seen. So, I just want to highlight that long-term piece, and we see that playing out over the course of the year. But for the quarter, Eric, additional thoughts?

Eric Andersen -- President

Yeah, Greg. Thanks. Look, I would say, Elyse, that reinsurance has been a strength-to-strength story for us over the last couple of years. It was a 7% growth in Q1 '22.

And honestly, the work that's been done was nothing short of spectacular around the 1/1 renewals. We had double-digit growth, in fact, double-digit growth in our STG advisory business, significant new wins in treaty. We feel really good about the performance of the team year to date. And looking forward, the work that the team is doing with their insurer clients and others is in demand, right? What the carriers are trying to do to manage their own portfolios as they navigate this marketplace has really -- our team is providing real value to them as they think through that.

So, really, really proud of the work that, that team has done, not only this quarter but over the last several years, and the future looks bright for it.

Elyse Greenspan -- Wells Fargo Securities -- Analyst

Thanks. And one last one, going back to that wealth tough Q2 comp comment. You guys saw 3% organic in wealth last Q2. So, was it just that these performance fees were elevated and there were just other businesses that offset that? It just -- it doesn't seem like a tough comp.

So, I just want to make sure I'm not missing something.

Christa Davies -- Chief Financial Officer

Yeah. It's simply about the performance fees. As you know, Elyse, performance fees are lumpy as we communicated.

Elyse Greenspan -- Wells Fargo Securities -- Analyst

OK. Thank you.

Operator

Thank you. Our next question comes from the line of David Motemaden with Evercore ISI. Please proceed with your question.

David Motemaden -- Evercore ISI -- Analyst

Hey, thanks. Good morning. So, I just had a question. It looked like more of the discretionary -- some of the discretionary parts of the business had a good quarter.

Travel and events and commercial risk solutions and human capital and health were both singled out in the press release and in the slides. I'm wondering if you could just talk about how the pipeline looks in those businesses, just given that you tend to be a little bit more economically sensitive?

Eric Andersen -- President

Sure. I would say, our health business had a very solid first quarter. The consumer solutions part of that was up 9%. Core health and benefits was up significantly.

Global benefits, human capital, double-digits, both in the analytics and the advisory and data solution spaces. So, really solid start for the year for them with a strong pipeline as they go through the rest of the year.

David Motemaden -- Evercore ISI -- Analyst

Got it. OK. Thanks. And then, I'm just looking at the capex and appreciate the outlook this year, the 200 million to 225 million.

If I just look back pre-COVID where it's running at that level or above that level, and it's been around 100 million less than that in 2020 and 2021, ticked up in the second half of 2022. I guess I'm wondering, is there -- should we be thinking about a bigger ramp, I guess, as we enter into 2024? Just maybe some of those investments that would have occurred during the COVID year sort of ramp up here as we exit.

Christa Davies -- Chief Financial Officer

Thanks so much for the question, David. I would say, we expect 200 million to 225 million for 2023. And then it's reasonable to think going forward, 2024 and beyond, that capex will grow in line with expenses. So, you're absolutely right that 2020 and 2021 will lower, really just because of the COVID situation.

And as we return to more normalized levels of capex, 2023 is a right normalized level to start with and then grow from there based on overall expense growth.

David Motemaden -- Evercore ISI -- Analyst

Got it. OK. OK. And then, maybe if I could just sneak one more in.

You mentioned a lot, Greg and Christa, just on Aon business services. And I was just wondering, taking a step back, how many employees do you have located in Aon business services and where you think you can get that to over the next couple of years, and what sort of margin implications that might have?

Christa Davies -- Chief Financial Officer

Yeah. Look, thank you for the question. And what we would say is we're incredibly excited about Aon business services as a core part of Aon business strategy. It's bringing together the firm in one organization led by Mindy Simon, our fantastic COO, and bringing together an organization to drive efficiency, to drive improved service and quality, and to drive innovation at scale.

Because a lot of the investments we're making, David, you saw in these IT platforms and security and infrastructure, are helping us scale insights and data analytics to clients to actually deliver impact. And so, we're really excited about the potential to drive productivity and margin expansion from ABS but, equally, to drive improved service and quality to clients and to allow us to accelerate innovation in one area of the business across all of our countries and all of our clients immediately. And so, it's proven to be an amazing competitive advantage for us over the next many years.

David Motemaden -- Evercore ISI -- Analyst

Great. Thank you.

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

Unknown speaker

Good morning. This is Jack on for Mike. Just had one follow-up regarding the M&A outlook. First-quarter M&A volumes in the brokerage space are down over 25% according to some media reports.

So, wondering, would Aon consider moving downmarket in terms of employer size into the U.S. or European insurance brokerage, middle-market area where Aon currently isn't a major player, given that some of the private equity players are being less aggressive?

Greg Case -- Chief Executive Officer

I would say from our standpoint, as Christa highlighted before, we've got a terrific pipeline, lots of opportunities we see. We're always going to be looking at them in terms of how they're going to strengthen and build our business. So, this is really content capability we can scale around the firm. So, you might imagine, we look across the entire spectrum, and we continue to do that, looking for these kinds of opportunities at a return on invested capital criteria that sort of meets the benchmark, which is really buying back, which has the standard.

So, we're looking broad-based and looking for opportunities around the world.

Unknown speaker

Got it. Thank you. And then, maybe a follow-up on the more discretionary parts of your business. Some competitors have said that clients are acting as if some project work, which used to be maybe viewed as more discretionary, is now viewed as more necessary in today's world.

I guess just any thoughts on that. Is that something that you're also seeing?

Greg Case -- Chief Executive Officer

Yeah. We would -- absolutely. So, first, I just want to highlight, if you look back in kind of overall, what's discretionary and nondiscretionary as the baseline, very limited amounts of our business is really discretionary when you get down to it. There's sometimes timing is effective, not this year, but it's not this year, it's next year.

And so, a very low level from that standpoint. But what you're highlighting is exactly correct. Complexity is driving demand, and complexity and urgency is driving demand. And analytics around that at which we have make some of the -- some of these what would have been really would be nice to do almost necessary to do, particularly as you think about risk connecting with human capital and the dynamic that comes with that.

Eric, why don't you add to that?

Eric Andersen -- President

Yeah. I would maybe offer two examples. One is around wellness and the human capital business that historically would have been considered discretionary. You can't have a conversation today with a chief people officer who is thinking about health overall, including wellness as people think about return to work, how they engage their own colleagues.

And so, that is becoming more of a blended discussion than ever before. And the other piece, I think, Greg, that jumps out is the risk analytics and the advisory work around the commercial risk business that you would have historically said would have been more discretionary in nature. Today, as the clients are thinking through how they navigate this challenging market, whether it's captives, whether it's risk studies, trying to understand their total cost of risk, and how they can actually manage the process better. Those skills that we're able to bring to clients are in significant demand and feel more a part of the process going forward than maybe on a project-by-project basis, just to give you two examples.

Unknown speaker

Thank you.

Eric Andersen -- President

Thank you.

Thank you. Our next question comes from the line of Meyer Shields with KBW. Please proceed with your question.

Meyer Shields -- Keefe, Bruyette and Woods -- Analyst

Thanks. Two quick ones. First, can we get a little color on what actually drove the performance fees last year? Like what are the -- what was the performance that led to that fee? And when can we expect that sort of thing to recur?

Eric Andersen -- President

I would look at it as an assets under management discussion in terms of the volatility of the market. And so, as that comes back around, you'll begin to see more of a stable platform on that. But that's what drove it in the second quarter.

Meyer Shields -- Keefe, Bruyette and Woods -- Analyst

OK. Fantastic. That's perfect. And second question, Greg.

I think this is for Greg. So, we saw almost 200 basis points of improvement in the comp ratio. Should we think about that as improved efficiency? Or is there a concern maybe that there are some roles that need to be filled?

Greg Case -- Chief Executive Officer

So, it's overall -- I mean, sort of overall, as you think about, Meyer, where we are sort of in the process, we were looking at this across holistically, what we're doing, continuing, as Christa said, make investments across the business to strengthen the business to [Inaudible] do that. Aon business services underneath that drives efficiency, which Christa described. I do want to emphasize, it's not just efficiency. Aon business services is so much more than efficiency.

It is innovation at scale, and it is better service and capability, but it does drive efficiency. Let's be clear. It helps individual colleagues be more effective in serving clients and then groups of colleagues more effective serving clients. So, you're seeing that reflected in all through.

But we have continued to make really substantial investments in talent and content capability, and we'll continue to do that. Christa, what else would you add to that?

Christa Davies -- Chief Financial Officer

The thing I would say, Meyer, is you're observing lumpiness in expenses in any one quarter, and we really think about margin expansion over the course of a full year. And we commit to drive margin expansion in 2023 and every year after that. And we think about margins over the course of the full year. And we're balancing a number of factors, including investments in people, T&E and IT, as well as the impacts of FX and fiduciary investment income, all with the overall goal of delivering adjusted margin expansion net of sustainable investment and long-term growth.

And that's exactly what's happening in Q1 and will happen for the rest of 2023.

Meyer Shields -- Keefe, Bruyette and Woods -- Analyst

OK. Perfect. Thank you very much.

Operator

Thank you. Our next question comes from the line of Michael Ward with Citigroup. Please proceed with your question.

Michael Ward -- Citi -- Analyst

Thanks, guys. Good morning. I think you guys implied that the T&E headwind was much larger in the first quarter. I was wondering if that means you expect more margin expansion over the balance of the year?

Christa Davies -- Chief Financial Officer

Michael, we don't give margin expansion guidance for the full year. What we can say is over the last 12 years, we've driven 1,120 basis points of margin expansion or approximately 90 basis points per year. It is -- we expect to drive margin expansion each and every year. It's not neatly 90 basis points per year because it's lumpy.

And it really what it is. It's us driving gross margin expansion net of investments. And the amount we invest every year is dependent upon our opportunities for long-term growth. I would say, specifically on your T&E point, T&E was a bigger headwind this quarter because Q1 '22 had a very low T&E expense given what was going on with COVID.

Michael Ward -- Citi -- Analyst

Got it. OK. And then, a somewhat different question. I wanted to ask about the IT solutions business.

I believe it's somewhat small for you guys. I think you've quoted like $1 billion of lending that you've helped achieve there. So, I was just hoping you could maybe discuss this business and maybe quantify as earnings or revenues, if possible, and maybe even size that -- the market of this business.

Greg Case -- Chief Executive Officer

Michael, first of all, thanks for raising it. I'm happy to address it. And Eric and I can give both -- give his color commentary on this, too. But this is a phenomenal area.

If you think about sort of things we do every day to move to the market, this is an area in which you step back, I think, total addressable market, what could that be? Well, start to zero right now. And what could it build to? 85% of the world's value is connected back in tangible assets. So, my gosh, what should this be? By the way, what has our industry done to defend those assets? Nothing today until we started to really understand how to value IP such that it could be insured, which means it's a real tradable asset, which means you can borrow against it. And you're right.

We've done a number of deals over the course of the last 18, 24 months, which has amounted to $1 billion of debt, which is fantastic. It means these entrepreneurs are raising growth capital without giving up ownership. But just think about that, raising growth capital without giving up ownership. Who's interested in doing that if you're an entrepreneur? And the answer is that market is massive.

It's going to take time to develop. It takes time to build markets as it always does. And we love the momentum, and we love the possibilities and potential. We're not going to quantify what it means.

We'll see it will play out over time, but it really does have a very specific application, and we're quite excited about the progress. Eric, what else would you add to that?

Eric Andersen -- President

Yeah. Maybe just to go a little bit on it. Certainly, the CPI lending piece is what we have been talking about the most that's probably the most advanced in terms of the valuation process. But you've also got M&A due diligence around IP.

You've got traditional IP liability where a corporate is not actually trying to lend against it but want us to protect it. But to make all that happen, you need a couple of things, right, which is what we've been building over the last period of time. You need the valuation, right? How do you actually value IP, both in an upmarket and a stressed market. How do you liquidate it? How do you get insurer partners to devote capital to it to understand the risk themselves, to trust the valuation process, to understand how you would liquidate an example? So, there's a whole ecosystem that we've been building that we are very optimistic about.

And as Greg said, we've been building it a little bit each time. And the team is focused or connected in with our commercial risk partners as they build market. They're connected into understanding how to get it in front of clients and build the financial institution relationships. So, there's a lot to it that has been happening for us.

And we're excited about the future of it and started to see a little bit of progress last year.

Michael Ward -- Citi -- Analyst

Thanks so much, guys.

Thank you. Our next question comes from the line of Josh Shanker with Bank of America. Please proceed with your question.

Josh Shanker -- Bank of America Merrill Lynch -- Analyst

Thank you all for taking my question. Good morning to you. First quarter is the strongest quarter for the reinsurance segment, obviously. In the back half of last year, you had a lot of acquisition-related growth in reinsurance, not so much in 1Q.

I mismodeled it. I'm just looking at 2Q, which is a smaller quarter for revenues in reinsurance. First, maybe you can help me think about the acquisition revenue piece for 2Q? It really won't matter later in the year. But given that volatility over the last three quarters, trying to be smart about it.

Eric Andersen -- President

Why don't I take a crack at it? Listen, we -- the reinsurance business is kind of almost a tale of two halves. Certainly, the first half is much more dominated by treaty business. Think about that through the first half of this year as always. Still some good facultative business.

And obviously, with the acquisition of Tyche, the ability to do those advisory services throughout the year. The second half is much more weighted to capital market transactions, i.e., cat bonds, as well as facultative reinsurance, and then some casualty reinsurance that tends to go through the year as well. But if you're trying to think through the weighting of the year, property cat, which is what a lot of people focus on, is largely done by the end of June, if that helps.

Josh Shanker -- Bank of America Merrill Lynch -- Analyst

In terms of the acquisition, is there a property cat in that acquisition?

Eric Andersen -- President

I'm not exactly sure by what you mean by acquisition.

Josh Shanker -- Bank of America Merrill Lynch -- Analyst

I'm saying that your 9% boost to revenues in the back half of '22 in the reinsurance segment due to acquisitions and only 1% in 1Q, I assume there's a 12-month impact on any acquisitions you make. It was less pronounced because of the volumes, I guess, in 1Q. I'm trying to think -- yeah. Yeah.

Eric Andersen -- President

Got it. So, the acquisition around Tyche was much more advisory services, less property cat, but more pricing support and data and analytics support for those clients. A lot of the activity in the second half of last year was driven by FAC and cat bonds. So, I would say that's how I would think about it.

Josh Shanker -- Bank of America Merrill Lynch -- Analyst

OK. And then I want to follow up a little bit on --

Christa Davies -- Chief Financial Officer

And, Josh --

Josh Shanker -- Bank of America Merrill Lynch -- Analyst

Yeah. Go ahead.

Christa Davies -- Chief Financial Officer

Well, sorry. Josh, we closed Tyche in Q1. And so, you will see Tyche growth included in organic growth from Q2 onwards. It will be under, as Eric said, our strategy and technology group with be advisory part of reinsurance.

Josh Shanker -- Bank of America Merrill Lynch -- Analyst

That's perfect. Thank you, Christa. And I just wanted to follow up on Mike's question about T&E just a little bit. Clearly, there's a variance between 1Q '23 T&E and 1Q '22.

But in my mind, I would imagine the variance would have been greater between 4Q '22 and 4Q '21. And maybe [Inaudible] tell us a little something about the business cycle and whatnot. If you're spending more on T&E now, is that a broad situation with regards to a resumption of how your clients are spending? And two, should we expect that T&E headwind is really a '23 event more so than a '22 event?

Christa Davies -- Chief Financial Officer

Great question, Josh. And so, what we would say is, look, we wouldn't overly read into any one quarter. It's lumpy quarter to quarter. And what we would say is, think about margin expansion for the full year, which is driven by a lot of things.

It's been driven by our investment in people and technology to drive long-term growth, offset by some investments in T&E, a headwind from FX. There's a lot of things going into this charge. But really, that's why we come back to margin expansion for the full-year 2023, similar to the margin expansion we've driven over the last 12 years of 1,120 basis points or approximately 90 basis points a year.

Josh Shanker -- Bank of America Merrill Lynch -- Analyst

Well, I appreciate you staying on message. And thank you very much, Christa, for [Inaudible].

Christa Davies -- Chief Financial Officer

Thanks, Josh.
