The notice of the meeting given it is now past 8:00 A.M. British Summer Time. I'm informed that there is a quorum present. I declare that the annual meeting is open. There are 11 items of business on today's agenda, as set forth in the proxy materials sent to shareholders on or about May. Later in the program Ernst & Young will be available for appropriate questions during the Q&A portion of the meeting. For those of you listening to our meeting this morning via audio webcast, the slides that accompany the presentation at www.aon.com. Secretary.
Thank you, Lester. Notice of this annual general meeting, together with Aon's proxy statement and annual reports for the year ended December 31, 2017, were made available beginning on May 4, 2018, to shareholders of record as of the close of business on April 24, 2018. Aon has appointed Miguel Davies of Computershare Investor Services PLC as Inspector of Election for the voting at the annual general meeting. In accordance with the articles of association of the company, voting today will be done by way of a poll on each of the resolutions put to the meeting. This is seen as best practice, as it gives all shareholders the opportunity to participate in the decision-making of the company and have their votes recorded, even if they are unable to attend the meeting in person. As noted by our chairman, a quorum is present at today's annual general meeting.
Based on a preliminary report from the Inspector of Election, of the 244,745,393 shares entitled to vote at the meeting, more than 222 million shares, representing approximately 91% of the total voting rights of all of the shareholders entitled to vote, are present in person or by proxy at this meeting. As a result, I declare that a quorum is present. We will proceed with the meeting. A copy of the minutes of the 2017 annual general meeting of Aon shareholders is available at this meeting for inspection. I'd like to turn the meeting over to Aon CEO Greg Case.
Thank you. I appreciate it. On behalf of management, I'd like to welcome our shareholders who are in the room and shareholders from around the world that joined in on the webcast. We'd also, on behalf of management, like to thank our board of directors for their invaluable guidance and assistance over the course of the year as we've shaped our strategy and progressed our firm. Thank you very much for that. A special welcome to Jeff Campbell, who's joining for his first shareholders meeting and first board meeting. Welcome, Jeff. Terrific. We'd also like to convey to our shareholders, your firm is in its strongest position it's been in its history. We continue to make progress on our journey to be the preeminent professional services firm in the world, focused on risk, retirement, and health, underpinned by data and analytics.
A number of solution areas the overall effort sort of are outlined on the next slide, which highlights five specific areas in Commercial Risk Solutions, where we have the number one position in the world, very fortunate and growing. In Reinsurance Solutions, where we are number one in treaty, number one in facultative, number one in Insurance-Linked Securities. In Retirement Solutions, where we advise on over $3 trillion in assets around the world, greater than 10% of the world's overall pension assets at $31 trillion at this point. In Health Solutions, we're the number one provider in Exchange Solutions and in health benefits around the world. In data analytics, where we spend over $400 million a year investing in content capability to strengthen the firm. In addition to this platform and the organic investments, we also make investments in acquisitions. Highlighted here are six.
Townsend within our delegated group in a real estate investment, absolutely terrific. In Admix, in health in Brazil. In Henderson, U.K. investment in brokerage. In UMG, another brokerage investment in the Netherlands, making us number one in that country. In cut-e, which is a talent acquisition that we've made, strengthened our position quite substantially. Stroz Friedberg, which has substantially strengthened our position and capability in cyber and related topics. Overall, a firm which is continuing to progress. While a long way to go on our journey, feel very good about our progress and our current position. I'd now like to turn this over to Christa Davies, our CFO, to discuss more our financial position. Christa, over to you.
Thank you very much, Greg, and welcome to all of our shareholders. We're delighted with the financial results of 2017, and we do believe that we're positioned for further acceleration of growth on the top line, revenue, further margin expansion, and double-digit free cash flow growth for the foreseeable future. As we look at free cash flow growth over the long term, we've really made substantial progress on return on invested capital as the metric we use to allocate capital across the firm. Cash on cash returns, we're now at 17.8%, the most substantial increase over the last six or seven years. More importantly than that, I think, is the free cash flow margin, which is really what we're looking at. Free cash flow divided by revenue. Every dollar of revenue we bring into the firm, how much of that can we translate through to free cash flow?
That's now also at 17.8%. We continue to grow that through continued acceleration of revenue growth, expansion of margin, improvements in working capital and CapEx and pension and all the things we're working on to improve each dollar of revenue to bring in, it translates into free cash flow. We do expect in the near term to deliver on this, the greater than $7.97 in EPS in 2018, and continue to drive double-digit free cash flow growth for the foreseeable future. With that, I'll hand back to Lester. Thank you.
Thank you, Christa and Greg for the update. We're now ready to take your questions. Anyone who wishes to ask a question, please raise your hand and we'll bring you a microphone. Seeing no questions, I'd like to now turn the meeting back to Peter for his resolutions to be considered at today's annual meeting.
Thank you. Jeffrey C. Campbell has been nominated for election as a director of the company. The following individuals have been nominated for re-election as directors of the company. Each will be elected or re-elected by way of a separate ordinary resolution of the company, Lester B. Knight, Gregory C. Case, Jin-Yong Cai, Fulvio Conti, Cheryl A. Francis, J. Michael Losh, Richard B. Myers, Richard C. Notebaert, Gloria Santona, Carolyn Woo. There are nine additional matters scheduled to be acted upon by ordinary resolution at this meeting. One additional matter scheduled to be acted upon by special resolution. In accordance with the recommendation of the board of directors, I move the following propositions for approval by an ordinary resolution. An advisory vote on the compensation of the named executive officers as set forth in Aon's proxy statement.
An advisory vote on the directors' remuneration report included in Aon's annual report and accounts. The receipt of Aon's annual report and accounts for the year ended December 31, 2017, together with reports of the directors and the auditor. The ratification of the appointment of Ernst & Young LLP as Aon's independent registered public accounting firm for the year ended December 31, 2018. The reappointment of Ernst & Young LLP as Aon's United Kingdom statutory auditor under the Companies Act 2006 to hold office from the conclusion of the meeting until the next annual general meeting at which accounts are laid before Aon. The authorization of the directors to determine Ernst & Young's remuneration as statutory auditor. The approval of the forms of share repurchase contracts and the repurchase counterparties through which Aon may conduct repurchases pursuant to the company's share repurchase program.
The authorization of the directors to exercise all powers of Aon to allot shares or grant shares, subscribe for or convert any security into shares in Aon. The authorization of Aon and its subsidiaries to make political donations and expenditures. As an ordinary resolution, each resolution requires a simple majority of the votes cast to be voted in favor of the resolution to pass. In addition, in accordance with the recommendation of the board of directors, I move the authorization of the board of directors to allot equity securities for cash without the rights of preemption provided by the Companies Act 2006 for approval by special resolution. As a special resolution, the resolution requires that shareholders representing at least 75% of the votes cast to be voted in favor of the resolution to pass.
As required by our articles of association, the vote will be taken on a poll. As a result, each person represented in person or by proxy is entitled to one vote for every share held. I will now turn the meeting over to Lester.
Thank you, Peter. We will now conduct the official business of the meeting. It is now 8:10 A.M. British Summer Time. I formally propose that each of the resolutions set out in the notice of the meeting are put to the meeting. I declare the polls open for voting on all of the resolutions. Let me spend a moment reviewing the voting procedures. Proxy statements and proxy voting cards were sent to all shareholders prior to this meeting. Those of you who returned proxies prior to this meeting authorized the persons named in the proxy to vote on all proposals coming before the meeting. Similarly, if you granted your proxy over the telephone or internet, you do not need to vote during the meeting. Any shareholder who has not submitted a proxy or who wishes to change his or her vote, please stand and you will be given a ballot.
Anyone who still has a proxy card should now hand it to the Inspector of Election so it may be counted as a vote executed in person at the meeting. Will the Inspector of Election please collect all ballots at this time. Are all ballots in? Thank you. All ballots are in. I now declare the polls closed. Peter, please note the time of the closing of the polls for the minutes. The Inspector of Election is requested to tabulate the proxies and ballots and report the final voting results to the company secretary. Peter will announce the provisional results as soon as possible. Now, it's my pleasure to introduce our non-executive directors. I would like to ask the directors to stand please to be recognized. Jin-Yong Cai. Jeff Campbell. Fulvio Conti. Cheryl Francis. Mike Losh. Dick Myers. Dick Notebaert. Gloria Santona. Carolyn Woo.
Please join me in thanking the directors for all the time and effort they devote on behalf of Aon and its shareholders. I would also like to thank Greg and Christa and their management team for all their efforts on behalf of Aon and its shareholders. Now I'd like to ask Peter to report on the voting.
Following a review of proxies received and tabulated, each nominee for election or re-election as director received a majority of the votes cast at this meeting. In addition, each other proposed resolution has been approved as an ordinary or special resolution as required. These results are provisional. The Inspector of Election will furnish a written report of the final vote count, which will be attached as an exhibit to the minutes of this meeting, reported in a filing by Aon with the Securities and Exchange Commission and made available on the company's website. I will now turn the meeting back to Lester for closing remarks.
Thank you, Peter. That concludes the business of the meeting. I'd like to express our sincere appreciation to those shareholders who attended, and also those who submitted proxies but were unable to attend. I now declare the meeting closed. Thank you.
