Prepared Remarks:

Operator

Welcome and thank you for holding. Welcome to Aon plc's First Quarter 2018 Earnings Conference Call. At this time, all parties will be in a listen-only mode until the question-and-answer portion of today's call. If anyone has an objection, you may disconnect your line at this time.

I would also like to remind all parties that this call is being recorded and that 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 2018 results, as well as having been posted on our website.

Now it is my pleasure to turn the call over to Greg Case, President and CEO of Aon plc.

Gregory Case -- President and Chief Executive Officer

Thanks very much, operator, and good morning, everyone. Welcome to our First Quarter 2018 Conference Call. Joining me today is our CFO, Christa Davies. For your reference, I would note that there slides available on our website to follow along with our commentary today.

Before we discuss the financial results of the quarter, I'd like to reflect on Aon overall and our decade-long mission to be the leading global professional services firm, delivering a broad range of risk, retirement, and health solutions, enabled by proprietary data and analytics. We have taken significant steps to evolve into the firm you see today. As you know, nearly a year ago, we completed a divestiture of our outsourcing platform, a meaningful acceleration of our proven strategy.

The divestiture was just one step in our journey but it was a step that provided a further catalyst for our actions to unlock the next wave of shareholder value, as it reinforced our focus as a professional services firm, further aligns Aon's portfolio around our clients' highest priorities, generates significant capital to accelerate investment in innovation and emerging client needs, provides a catalyst to unite our firm under one operating model, creating greater efficiency and operating leverage, and reinforces our return on invested capital decision-making priority, and emphasis on delivering double-digit free cash flow growth over the long term.

Our optimism is built through our conviction that these actions will substantially strengthen our firm on the heels of a decade of industry-leading improvement and innovation for our clients and shareholders. With this momentum, we're already seeing improvement in our growth profile, driven by new investment in high-growth, high-margin areas across our portfolio. Organic revenue has increased from 3% in both 2014 and 2015 to 4% in 2016 and 2017. Our journey continues as we focus on driving greater innovation and more insightful content to deliver improved outcomes on behalf of our clients. Stronger growth, combined with increased operating leverage and free cash flow margin, reinforces our long-term outlook and significant upside we anticipate in the value of our firm over the coming years.

Now turning to the quarter on Page 5 of the presentation. Consistent with previous quarters, I'd like to cover two areas before turning the call over to Christa for further financial review. First, our performance against key metrics we communicate to shareholders. Second, overall organic growth performance, including continued areas of strategic investment. I would also note that the financial results discussed on today's conference call and shown in the presentation slides are all on a comparable basis year-over-year, adjusting 2017 results retrospectively to pro forma amounts, which include the impact of the revenue recognition accounting change that was formally adopted as of the first quarter 2018.

On the first topic, our performance versus key metrics, each quarter we measure our performance against the key metrics we focus on achieving over the course of the year: grow organically, expand margins, increase earnings per share, and deliver double-digit free cash flow growth. In the first quarter, organic revenue growth was 3% overall, driven by strong growth in reinsurance and commercial risk solutions, also noting double-digit growth overall in total revenue. Operating margin increased 230 basis points and operating income increased 22%, primarily reflecting savings from investments in our Aon United operating model and core operational improvement.

EPS increased 26% to $2.97, reflecting both strong operating performance and effective capital management, partially offset by a higher effective tax rate. And, finally, adjusted free cash flow increased $28 million, or 16%, when excluding the near-term impacts resulting from the divestiture, primarily reflecting strong operational improvement. Overall, a strong start to the year, with positive performance across each of our key metrics in what is now our seasonally largest quarter.

Turning to Slide 7, on the second topic, organic growth and strategic investments. Reported revenue growth in the first quarter increased 13% year-over-year, or 8% excluding favorable FX translation, which is an acceleration above historical levels of 6%. Organic revenue growth was 3% overall in the first quarter, driven by strong growth in both reinsurance and commercial risk solutions.

Reflecting on each of our four growth platforms, in commercial risk solutions, organic revenue growth was 4%, an acceleration from 2% in the prior year quarter. On average globally, exposures were modestly positive and the impact from pricing was modestly negative, resulting in a relatively stable market impact overall. We saw solid growth globally across most geographies, driven by more than $200 million of total new business generation and strong management of our renewal book portfolio. Results reflect strong growth across the Americas, including double-digit growth in both Canada and Latin America, as well as particular strength in U.S. retail, driven by a 17% increase in new business generation. Internationally, growth was driven by strength in the EMEA region, again highlighted by substantial new business generation, up 26% versus the prior year. Finally, total revenue growth, excluding favorable FX, increased 14%, driven by the inclusion of our UMG and Henderson acquisitions in EMEA.

In reinsurance solutions, organic revenue growth was 6%, an acceleration from 4% in the prior year quarter, a really strong performance in what is now our seasonally largest quarter for reinsurance. Market impact was modestly positive on results in the quarter, reflecting both a continuation of moderating pricing and modest upward pressure in loss-exposed geographies, partially offset by clients adjusting their buying behavior as industry pricing fluctuates. Results reflect strong growth across every major category again this quarter, including treaty, facultative, and capital markets transactions. We saw particular strength in treaty placements, driven by another quarter of net new business generation.

Looking ahead for reinsurance, we would remind you of the strong second half comparable for 2018, as 2017 benefited from a higher than normal catastrophe season in capital markets activity, albeit in what are now our seasonably smallest quarters.

In retirement solutions, organic revenue growth was flat compared to 2% in the prior year quarter. Results reflect solid growth in investment consulting, including continued double-digit growth in delegated investment management solutions, reflecting an increase in client demand for Aon's tailored solutions and objective advice. We also saw growth in our talent, rewards, and performance practice for assessment services, an area of recent M&A investment. Results were offset by a modest decline in project related work and an unfavorable impact from timing of certain revenue into future quarters in the talent practice.

In health solutions, organic revenue growth was flat against a strong comparable of 15% in the prior year quarter. We saw solid growth in health and benefits brokerage, highlighted by particular strength internationally across Asia and the EMEA regions, driven by strong management of the renewal book portfolio. We also saw solid growth in the U.S., with double-digit growth in voluntary benefits, an area where we have seen increasing client demand as employers look to tailor their benefit strategies to offer their employees cost-effective options outside of traditional coverage. Results in the quarter were unfavorably impacted by certain project-related work that benefited the prior year quarter in our healthcare exchange business.

In data and analytic services, organic revenue growth was 1% compared to 6% in the prior year quarter. We saw continued growth in our core Affinity business, with particular strength in the U.S. and EMEA. Results in the quarter were offset by an anticipated unfavorable impact from changes in certain client contracts, most notably the transition of a certain government contract in our flood business.

Overall, a strong start to the year despite some quarterly noise due to timing and tough prior year comparables. Driven by improved portfolio mix and significant investment in high growth areas, we continue to position the firm for improved long-term growth.

Turning to Slide 8 to discuss areas of strategic investment. Clients continue to navigate an increasingly volatile world, with natural disasters combined with economic, demographic, geopolitical forces, and the exponential pace of technology change all converging to create a challenging new reality for businesses. Aon has a strong track record of allocating capital to developing innovative, first-to-market solutions to help solve problems and create differentiated value in response to specific client needs. These strategic investments in high-growth areas, driven by our ROIC decision-making process, are improving the firm's long-term growth profile and increasing operating leverage across the portfolio.

We're investing organically and through M&A across the portfolio in areas such as: data and analytics, to deliver better client outcomes through content-driven insight; cyber risk advisory, expanding on the acquisition of Stroz Friedberg; health and elective benefits brokerage, as global employers are increasingly focused on improving their overall benefits packages; healthcare exchanges, where we offer the broadest set of solutions in health geographically with the recent acquisitions of UMG and Henderson, reinforcing our industry-leading position in EMEA; and, finally, in delegated investment management solutions, a business with rapidly growing client demand, with the recent acquisition of the Townsend Group, bringing a great depth of expertise and real estate assets to our distribution scale and increasing our ability to provide alternative private market assets.

In summary, results in the first quarter represent a strong start to the year with significant double-digit growth across revenue, operating income, earnings per share, and adjusted free cash flow. We believe our unmatched level of investment in content and client-serving capabilities combined with improved operational performance through our Aon United operating model and effective capital management place us on track to exceed $7.97 of earnings per share in 2018, and more important, unlock significant shareholder value through double-digit free cash flow growth over the long-term. I'm now pleased to turn the call over to Christa for further financial review. Christa?

Christa Davies -- Executive Vice President and Chief Financial Officer

Thank you so much, Greg, and good morning, everyone. As Greg noted, our first quarter results reflect positive performance across each of our key metrics, highlighted by strong organic revenue growth in commercial risk and reinsurance solutions, substantial operation improvement, and double-digit growth in adjusted free cash flow. We are continuing to drive efficiencies in our operating model and allocate capital to the highest return opportunities.

As Greg previously highlighted, the financials discussed on today's conference call and shared in the presentation slides are all on a comparable basis year-over-year, adjusting 2017 results retrospectively to pro forma amounts that include the impact of the revenue recognition accounting change that was formally adopted as of the first quarter 2018. Please refer to Pages 11 to 15 of the press release schedules for financials that provide a comparable year-over-year view. And similar to last year, we've provided nine quarters of comparable financials in Excel format on our Investor Relations website.

Turning to Slide 10 of the presentation, our core EPS from continuing operations, excluding certain items, increased 26% to $2.97 per share for the first quarter, compared to $2.35 in the prior year quarter. Certain items that were adjusted for in the core EPS performance and highlighted in the schedules on Page 11 of the press release include non-cash intangible asset amortization, non-cash restructuring charges, and non-cash expenses related to pension settlements.

Results included a net $0.12 per share favorable impact from changes in foreign currency exchange rates and in certain hedging programs, including a $0.19 per share favorable impact from FX translation, primarily driven by a weaker U.S. dollar versus the euro, partially offset by a $0.03 per share loss on the remeasurement of assets and liabilities in non-functional currencies recognized in other expense. And, lastly, the prior year quarter benefited from a $12 million, or $0.04 per share, reduction in expenses related to certain hedging programs. If currency were to remain stable at today's rates, we would expect foreign currency translation to have an immaterial impact in the second quarter and the remainder of 2018. Lastly, included in the results was a $7 million, or minus $0.02, unfavorable impact from losses on certain long-term investments recognized through other expense.

Turning to the next slide to discuss our strong operational performance. Operating income increased 22% and operating margin improved 230 basis points to 31.8% compared to the prior year quarter. Operating income primarily reflects 160 basis points of savings from restricting initiatives and other operational improvements before any reinvestment and 90 basis points of core improvement. This was partially offset by a minus 20 point net unfavorable impact from FX translation in certain hedging programs.

From a dollar standpoint, operating income increased $174 million, with $52 million driven by incremental savings before reinvestment and $45 million of net favorable impact from FX translation in certain hedging programs. The remaining $77 million, or 10% growth year-over-year, was driven by solid organic revenue growth and core operational improvement. A strong start to the year operationally as we continue to execute against our multi-year investment in the firm and improve on invested capital across the portfolio.

I'd like to spend a few minutes discussing the investments we're making to create our next-generation global business services model that allow for better scalability, flexibility, and enhanced colleague and client experience. These investments are intended to create one operating model with increased operating leverage. Our primary investment areas are across IT, real estate, and people. In IT, we expect to create greater insights from data center optimization, application management, and strategic vendor consolidation. In real estate, we expect to drive greater collaboration and engagement through real estate portfolio optimization. And in people, we expect to create scalable and efficient operations, using centers of excellence and third-party providers.

As part of these operating model investments, we expect to invest an estimated $1.175 billion in total cash over the three-year program from 2017 through 2019. These investments include an estimated $975 million of cash charges. We incurred $497 million of expense and spent $280 million of cash in 2017. Future cash outlay is expected to increase modestly in 2018 then expected to decline each year thereafter. And an estimated $200 million of incremental capital expenditure investment, with $27 million incurred in 2017, approximately $100 million expected in 2018, and $70 million expected in 2019. There is an additional estimated $50 million of non-cash charges included as part of asset impairments.

Overall, we expect these investments and other expense discipline initiatives to deliver $450 million of estimated annual savings in 2019 before any potential reinvestment. Further, we have been deploying the balance of the proceeds from the sale of our outsourcing business to the highest return on capital opportunities, including investments in high-growth, high-margin areas across our portfolio and direct return to shareholders through share repurchase.

Turning to the next page, in the first quarter we incurred $74 million of restructuring-related charges, compared to $144 million in the prior year quarter, primarily relating to workforce reduction and other general initiatives. Since inception, we've incurred $571 million of restructuring-related charges, representing 56% of the updated total program estimate. The cash impact in the first quarter was an outflow of $98 million, compared to $31 million in the prior year quarter. We also incurred $15 million of additional capital expenditure, compared to $1 million in the prior year quarter. We recognized $63 million of savings in the first quarter, compared to $11 million in the prior year quarter, and $228 million of savings since inception of the program, representing 51% of the expected $450 million total program savings.

Now let me discuss a few of the line items outside of operations on Slide 14. Interest income increased $2 million to $4 million, reflecting additional income earned on modestly higher cash balances compared to the prior year quarter. Interest expense was similar at $70 million. Pension income increased $1 million to $9 million. As noted at year-end, beginning in Q1 of 2018, we adopted a new accounting standard that shifted the financial components of net periodic pension cost and net periodic post-retirement benefit cost from above the line in compensation and benefit expense to below the line as part of other income expense.

Other expense of $17 million primarily includes $10 million, or minus $0.03, of losses due to the unfavorable impact of exchange rates on the remeasurement of assets and liabilities in non-functional currencies, as well as $7 million, or minus $0.02, of losses on certain long-term investments. Based on current assumptions, we believe that approximately $10 million per quarter is the right run rate to model for other income expense in 2018, primarily related to pension income, excluding all other items we do not forecast that could be favorable or unfavorable in any given period.

Turning to taxes, the adjusted effects of tax rate on net income from continuing operations, excluding the applicable tax impact associated with certain non-GAAP adjustments, increased to 16.5%, compared to 13.3% in the prior year quarter, primarily driven by changes in geographic distribution of income as well as various impacts relating from U.S. tax reform. The adjusted effective tax rate in both periods included a net favorable impact from certain discrete items, primarily relating to share-based compensation. We continue to believe the best estimate of our full-year, non-GAAP effective tax rate is approximately 19% based on current interpretation of changes in U.S. legislation, assumptions of geographic mix of income, and impact of discrete items.

Lastly, weighted average dilutive shares outstanding decreased 6% to 250.2 million in the first quarter, compared to 267 million in the prior year quarter, as we continue to effectively allocate capital including the repurchase of 3.9 million Class A ordinary shares for approximately $550 million in the first quarter. The company has approximately $4.9 billion of remaining authorizations under its share repurchase program. Actual shares outstanding on March 31st were 245.2 million and there are approximately 4 million additional dilutive equivalents. Estimated Q2 2018 beginning dilutive share count is approximately 249 million, subject to share price movement, share issuance, and share repurchase.

Now let me turn to the next slide to discuss our solid balance sheet and financial flexibility. At March 31, 2018, cash and short-term investments decreased to $715 million. Total debt outstanding increased modestly to $6.1 million. And total debt to EBITDA on a GAAP basis for continuing operations decreased to 2.6 times. As discussed previously, while debt to EBITDA will be initially elevated as a result of the sale of our outsourcing business, we expect to return back to the 2 to 2.5 times range by the end of 2018, driven by operational improvement.

Reported cash from operations for the first three months of 2018 decreased $42 million to $140 million, primarily driven by $67 million of incremental cash restructuring charges, partially offset by operational improvement. Excluding certain near-term impacts resulting from the divestiture, including restructuring initiatives, adjusted free cash flow increased $28 million, or 16%. Adjusted free cash flow growth was primarily driven by strong operational performance in the quarter. A reconciliation of adjusted free cash flow to reported cash flow from operations is provided in Appendix E of this presentation. As cash outlays from near-term restructuring initiatives wind down in 2019 and beyond, we would expect adjusted free cash flow to converge with reported free cash flow.

The new revenue recognition accounting change did not have an impact on total cash flow or free cash flow. Appendix F of the presentation provides a pro forma comparable view of cash flow from operations for the prior year, showing that cash flow is completely unaffected by the revenue recognition accounting change.

Turning to the next slide to discuss our free cash flow growth over the long-term, we value the firm based on free cash flow and allocate capital to maximize free cash flow returns. This disciplined capital management approach is focused on a decision-making process that maximizes return on invested capital, which we have consistently improved each year since 2010, increasing 610 basis points to 17.8% in 2017. We've also taken significant steps to maximize the translation of each dollar of revenue into the highest amount of free cash flow, including working capital initiatives and actions to manage our cash pension contributions. Since 2010, we've increased our free cash flow margin by nearly 1,000 basis points. In 2017, our free cash flow margin on an underlying basis, excluding the impacts of the divestiture, was 17.8%.

Looking forward, we expect two main drivers to continue to contribute to incremental free cash flow generation. The first is continued operational improvement, driven by accelerating organic revenue growth and further margin expansion. The second is working capital improvements, as we focus on closing the gap between receivables and payables. We expect working capital to contribute to free cash flow by over $500 million over the long-term.

In summary, performance in the first quarter reflects a strong start to the year and continued progress against the actions we're taking to strengthen the firm. We believe that accelerating revenue growth and continued operational improvement, combined with significant financial flexibility and strong adjusted free cash flow generation, position the firm to deliver on our near-term goal of exceeding $7.97 adjusted earnings per share in 2018. As Greg noted, we're excited about the long-term outlook and our ability to deliver double-digit free cash flow growth combined with an expected reduction in total shares outstanding, representing a substantial upside and what we believe is the next significant value creation opportunity for shareholders.

With that, I'd like to turn the call back over to the operator for questions.

Questions and Answers:

Operator

Thank you. We will now begin the question-and-answer session. Participants on the phone, if you would like to ask a question, you may press "*1". Please unmute your phone and record your name when prompted. Your name is required to introduce your question.

Our first question will come from Dave Styblo of Jefferies. You have an open line.

David Styblo -- Jefferies -- Analyst

Hi, there. Good morning and happy Friday, guys.

Gregory Case -- President and Chief Executive Officer

Same to you. Thanks.

David Styblo -- Jefferies -- Analyst

I wanted to just come back to Slide 11. I don't think I'm quite triangulating the math quite right on the margin expansion year-over-year. So, apples to apples, you're up 30 basis points on operating margin. 160 basis points of that is from the restructuring savings. And then I think the FX had a drag of 20 so that would have made it -- that accounts for another 20 basis points. So is the difference there of your operating margin -- you know what? I think I've actually just solved my own question. Sorry about that.

Christa Davies -- Executive Vice President and Chief Financial Officer

So you've got 90 basis points of margin expansion from the core, Dave. Does that make sense? Yeah.

David Styblo -- Jefferies -- Analyst

Yeah. I missed that last point there. Okay. So that's self-explanatory. As far as, as you go forward for the rest of the year and your outlook on organic growth, I know you guys don't typically give guidance. You started the year at 3% here and you do have some tough comps in reinsurance for the back half of the year. Management's goal has been to continue to accelerate organic growth over the next couple years here. Is that gonna be hard to do this year just given the dynamics from '17? Or do you guys already have visibility on some areas of new business wins that give you confidence that you can at least match last year's 4% or possibly even move it higher?

Gregory Case -- President and Chief Executive Officer

Yeah, David, our message is consistent. And while there's a little bit of noise back and forth on the different revenue lines in the quarter, when we think about the year in '18 and beyond '18, we view this quarter as just another quarter of on-track progression. So if you go back and think about sort of our investments in higher margin, higher growth areas, historically go back a few years ago, we're at 3%, 3%. The last two years we're at 4%, 4%. Again, on track to continue that progress. And if you think about what happened in the quarter, 13% reported, take out the FX, we're at 8%. By the way, that 8% is higher than our 10-year average reported, which is at 6%. So from our standpoint, this quarter is just another step on a progression for organic growth, margin improvement, and as Christa importantly pointed out, free cash flow growth improvement.

David Styblo -- Jefferies -- Analyst

Okay. And then more broadly, as you look across your portfolio in terms of maybe a matrix of both geographies and product lines or solutions, can you talk a little bit more about market share upside potential and margin expansion headroom? I'm just trying to get a sense if you're maxed out in some countries or solutions. And, similarly, what areas of your business are perhaps underperforming, not quite at targets, where you see opportunity, other than the things that you're doing with the BPO cost savings?

Gregory Case -- President and Chief Executive Officer

Well, let's come back and I'll sort of point you back, too. I'll talk about sort of top line and Christa maybe can comment on the margin piece a little bit as well. Listen, one of the things we're excited about, we talked a year ago about the divestiture of our outsourcing business, which was yet another catalyst for the next step in the progression of Aon. Both to reinforce our work as a professional services firm, it also reinforced strongly our ability to continue to bring together Aon United, how we deliver our global firm to our clients in a local way. And that means we can invest more and more in a single operating platform or single P&L. All these things are driving greater operating leverage and are fueling the performance improvement, the operating margin improvement you're seeing.

And then what we also did is broke out the five revenue lines so you could really see where we're making investments. And we like the opportunities across all five of the lines. In particular, areas to create net new demand. So if you think about in commercial risk, what we're doing in cyber to change the game in cyber to create net new demand, a real set of opportunities.

In reinsurance we see tremendous opportunities to create net new demand with what is a truly industry-leading leadership team. So think about what we just did or have done historically in the U.S. mortgage world, in which we created net new demand in the U.S. mortgage world to the tune of $10 billion in premium. You saw us just place what is a very, very unique cat bond in the marketplace, the first of its kind for the World Bank, for four countries who faced quake risk they couldn't recover from in prior periods. So these are real innovations in reinsurance.

You're seeing the same on the retirement side and what we're doing with delegated, on the health side and what we're doing with the exchanges, and then very excited about what we're doing in data and analytics to, again, create areas of net new demand. So, for us, Dave, we really did see the sale of the outsourcing business as a real catalyst. And what you see in the first quarter is just the continued progress against that.

But in terms of margin, Christa, anything you'd add to that?

Christa Davies -- Executive Vice President and Chief Financial Officer

Yeah. I mean, the thing I'd say, Dave, is we do see margins continuing to accelerate. And there are a number of things driving that. One obviously is bringing together the Aon operating model under one operating model and you can see the progress there in terms of the savings. $165 million of restructuring savings in 2017. We're on track to deliver the $300 million in savings in 2018. And again on track to deliver the $450 million of savings next year in 2019. So that's obviously contributing to margin expansion.

The second thing I'd say is we are continuing to improve on the core margins of our business, through great work across the whole of Aon, which is just terrific. And the third I'd say, which is really the area Greg highlighted, which is we continue to invest in higher revenue growth, higher margins, higher return on capital areas, which is building leverage into the business. And I think data and analytics is the best example of that. It's a very high-margin business. And that is translating through to higher free cash flow growth. So we're very excited about the future growth in revenue, margins, and free cash flow.

David Styblo -- Jefferies -- Analyst

Okay. Thank you.

Operator

Our next question will come from Sarah DeWitt of JP Morgan. You have an open line.

Sarah DeWitt -- JP Morgan -- Analyst

Hi, good morning. On the near-term goal of at least $7.97 of adjusted EPS this year, I imagine when you set it, you didn't assume that there'd be $0.16 of FX benefit this quarter. So should we be thinking about that as you could hit $7.97 this year ex-FX?

Christa Davies -- Executive Vice President and Chief Financial Officer

So, Sarah, at the time of the transaction in May 2017, we gave guidance of exceeding $7.97 EPS in 2018 as you said. We're not updating guidance on a quarterly basis based on tax headwinds, FX tailwinds, or, frankly, much stronger operating performance. We do believe we're on track to exceed $7.97 and the results in Q1 demonstrate this.

Sarah DeWitt -- JP Morgan -- Analyst

Okay. Alright. Thank you. And then just on the share buy backs. How should we think about the pace of that going forward? Is it a good proxy to think about adjusted income less dividends as being available for buy backs, given that's I think your preferred way to deploy given the returns in the business?

Christa Davies -- Executive Vice President and Chief Financial Officer

Yeah, I think that's absolutely right, Sarah. What I would say is, if you look at free cash flow, we've got a use of cash on restructuring, we've got a use of cash on dividends, and then that is essentially cash available for share repurchase, investment in organic opportunities, and investment in M&A. And as you've seen, we continue to invest in share repurchase because it remains the highest return on capital opportunity across Aon. And then the other thing I would note, Sarah, is as we grow operating income and free cash flow over the long-term, you should expect that we'll grow debt to keep that debt to EBITDA in line with the ratio I outlined.

Sarah DeWitt -- JP Morgan -- Analyst

Okay. Great. Thank you.

Operator

Our next question comes from Arash Soleimani of KBW. You have an open line.

Arash Soleimani -- Keefe, Bruyette & Woods -- Analyst

Thanks. Just a quick question in terms of the tax rate. I know before you put out a 19% expected rate for this year. Just curious if that has changed at all based on increased clarity that you may have received in terms of the tax code.

Christa Davies -- Executive Vice President and Chief Financial Officer

Arash, we do believe that 19% is the correct rate for the full-year 2018. And so what you're really seeing is a lower tax rate in Q1 and then a higher tax rate in Q2, Q3, and Q4 to average to 19% for the year.

Arash Soleimani -- Keefe, Bruyette & Woods -- Analyst

Okay. Thanks. And I guess just my next question is are you seeing any changes in the demand for cyber, especially with some of the European regulations?

Gregory Case -- President and Chief Executive Officer

Arash, as we've talked before, we actually see tremendous client need in this category. Virtually every client we talk to is addressing this question and it's a question that's sort of at the Board level, at the CEO level, but also down to the operations of all of our clients' businesses. So this is an area of increasing concern for them. And, as you highlight, the $450 billion of reported loss last year, there was, against that, $3 billion in premium, give or take. We were privileged to place a good portion of that. But if you think about $3 billion versus $450 billion, that's an area of substantial need and a great opportunity for us, as Aon and as an industry, to help our clients support that.

And that $450 billion, to your point, was largely U.S.-based. When you think about the adoption of GDPR and the data requirements in Europe, which literally kick in this month, the reported requirements go up, which means $450 billion is going to go to something that's closer to $1 trillion. So you're absolutely correct. This is an area of high, high need for our clients and an area of substantial opportunity for Aon, which is one of the reasons we've invested so heavily behind it, both in traditional ways, core brokerage and all the things we do around that, the arrangements we set up on behalf of clients, but also the investment we made in just content and insight in Stroz Friedberg, as an example, who have an extraordinary insight into specific incidents and how they occurred and why they occurred. And we're applying that to underwriting characteristics and criteria to create more opportunity for our clients.

Arash Soleimani -- Keefe, Bruyette & Woods -- Analyst

Thank you very much.

Operator

Our next question comes from Yaron Kinar of Goldman Sachs. You have an open line.

Yaron Kinar -- Goldman Sachs -- Analyst

Good morning, Greg and Christa. Just want to circle back to organic growth for a second. So, if I understand your comments correctly, ultimately we shouldn't read too much into maybe a bit of a slowdown in the first quarter here and, for the full-year, you still expect steady, if not accelerating, growth. Is that a fair summation?

Gregory Case -- President and Chief Executive Officer

Yaron, I think you summarized it very well. There might be some noise sort of back and forth on the different revenue lines but, again, take a step back, literally. We feel the trajectory continues very positively on the growth side for us. Again, going back over multiple years now, going back four years, 3% and 3%, going then to 4% and 4%, we think we're on a very good progression for the year. And if you look at reported overall as a firm, even though there was noise back and forth between the revenue lines, overall as a firm, we're at 3% organic, 8%, excluding FX, reported and 13% reported. So these are very, very strong levels that continue to reinforce the growth trajectory of Aon. And, again, we look at this as kind of a single P&L. This is Aon overall delivering a growth, top-line, and delivering operating improvement and free cash flow growth. And that set of characteristics continues to look very positive.

Yaron Kinar -- Goldman Sachs -- Analyst

Okay. And then maybe if I dig a little deeper into organic growth. You called out a couple of things there, specifically weaker project-related revenue in both retirement and health and also very strong growth in EMEA in commercial risk solutions. So I was just hoping that maybe you could give a little more color around the project-related revenue. And then on EMEA, can you maybe talk about how the UK is shaping up within EMEA? Is it also a contributor or are you seeing some weakening there that's offset by other growth in the region?

Gregory Case -- President and Chief Executive Officer

Well, let me make sure I get -- health first was, I think, what you were asking about specifically and then about EMEA and the UK. On the health side, again, this represents a category with just tremendous, monumental opportunity to assist clients that's currently strong and it's increasing. It's a category you've seen us invest in substantially, both organically and via M&A. Think about what we've done on the exchanges as well as M&A, things like Admix. We grew at 7% in 2017 and, just to your point, we see 2018 as yet another year of similar growth and progress. So all good things. There was a very strong comparable, 15% in 2017, and that was just some specific one-time initiatives to support clients, which were terrific. But as we think about the year, very, very strong in terms of how that's progressing.

And then on EMEA, we just have an exceptionally strong team in EMEA and the UK and they've done fantastically well. Double-digit new business growth, which has been absolutely spectacular across the region and in the UK. We've also added capability, as I talked before about our two acquisitions that have also come on line and done exceptionally well. So, for us, this is just an area of opportunity and it continues to build and we expect that progression to continue.

Yaron Kinar -- Goldman Sachs -- Analyst

And can you talk specifically about the project-related revenues, both in retirement and health?

Gregory Case -- President and Chief Executive Officer

Well, on the health side, it was really more around -- again, as we implement major programs for clients, occasionally there are programs, particularly around some of the exchange work that we do, that are one-time. And the conversions, and we had a number of those in the first quarter of 2017, which was terrific, but, again, it drove a 15% organic number in Q1. Again, if you think about, we ended up 7% for the year and that's what we see progressing over time.

And on the retirement side, it was really more around, as we described, it was really more timing than a specific project. And the timing was around, again, different initiatives we take on behalf of clients and how we're working on behalf of clients, that are going to roll into the second half of the year. Not the second quarter, but the second half of the year, that will fully balance out. And, again, no change to overall projection and views on the year in that category.

Thanks. I appreciate the color.

Our next question comes from Elyse Greenspan of Wells Fargo. You have an open line.

Elyse Greenspan -- Wells Fargo -- Analyst

Hi, good morning. My first question, just going back to the conversation on margins, you guys saw 230 basis points of margin improvement this quarter on 3% organic. Do you view that as a sustainable level? And I guess what I'm also thinking about is you guys told us there would be about -- to get to the $300 million, we have about $135 million of saves for the full-year. And you guys saw just under 40% of that level in the first quarter. So how do we think about the margin progression for the back three quarters, in relation to just a different number of savings coming through as well as the 230 basis points of margin improvement you saw in the first quarter?

Christa Davies -- Executive Vice President and Chief Financial Officer

One of the things we would say, Elyse, is, as we look at our revenue growth for the quarter, I know you're focused on organic, we really focus on total. Because M&A is absolutely contributing to top-line and bottom-line performance and we're incredibly excited about the $1 billion in M&A we did in 2016 and the $1 billion we did in 2017. And so, as we look at the 13% revenue growth for the quarter, that is absolutely contributing to margin expansion. And we do expect margins to continue to expand in the second half of the year, in the balance of the year, for full-year margin expansion. And if you think about the progress on margins for the full-year, that will continue to occur as the savings ramp in the balance of the year.

Elyse Greenspan -- Wells Fargo -- Analyst

Okay. And that was actually, to your point on the acquisitions, that was another question I had. So really two parts. As we think about modeling, you guys saw about 5% revenue growth from acquisitions this quarter. Can you help us just think through the amount that could come through in the balance three quarters? Kind of what rolls off and when or maybe just high level? And then in terms of margins, were the acquisitions that came through in revenue this quarter, were they accretive to your margins? Meaning are they running at stronger margins than the rest of your business?

Christa Davies -- Executive Vice President and Chief Financial Officer

Yeah. So, Elyse, we haven't given revenue or margin guidance on the acquisitions. What I would say on reported revenue is, if you look at the last ten years, reported revenue has been 6%. And so that's a pretty good way to model revenue and certainly the way we think about it. Obviously we're looking at the components of that that are driven from organic versus M&A versus FX. But 6% reported is not a bad way to think about it because it's happened over a 10-year period of time. As we think about margins, they're typically lower on a full-year basis in the first year because we've got a bunch of integration costs associated with them. And so that's definitely a way to think about acquisitions as they come in. They'll contribute to revenue. They'll be a little lower on margin in the first year. And then obviously for us to do M&A, it has to have a return on capital higher than buy back. So it's certainly gonna contribute in the long-term.

Elyse Greenspan -- Wells Fargo -- Analyst

Okay. Thank you. And then one last question. Just going back to free cash flow quickly, obviously just some moving parts each quarter, but the goal for the year, being 2018, is it still about double-digit off of the adjusted 2017? About that $1.8 billion number?

Christa Davies -- Executive Vice President and Chief Financial Officer

That is exactly right, Elyse. So what we would say is our long-term growth of free cash flow is double digits. If you take the $1.8 billion in 2017, we will grow double digits this year. And as you think about uses of free cash flow, 2018 is the peak year for restructuring the use of cash. And so as restructuring tails off in 2019 and every year after that, you'll see free cash flow accelerate.

Elyse Greenspan -- Wells Fargo -- Analyst

Okay. Thank you very much.
