It not only sets us apart from other professional services firms, it positions us to deliver consistently strong performance, as we did again in 2017.” DAN GLASER PRESIDENT AND CHIEF EXECUTIVE OFFICER MARSH & McLENNAN COMPANIES To our shareholders, 2017 was a year of disruption and challenge for the world. It tested the resilience of millions of people affected by extreme weather and natural disasters. It strained the limits of cooperation and diplomacy among nations and within governments. And it made demands on our larger society, as cultural flashpoints prompted us to articulate and reaffirm our fundamental values and beliefs. Underpinning this complex and dynamic landscape are issues related to risk, strategy and people. Marsh & McLennan’s expertise in these three core areas is at the heart of our sustained ability to create value. We develop solutions for clients that address the most pressing challenges of the day: shifting demographics, healthcare, cyber security, natural catastrophes and accelerating digital transformation, to list just a few. 1 I’m exceedingly proud of how our colleagues We also delivered margin expansion in both around the world harness our collective our Risk and Insurance Services and Consulting expertise to help address these challenges. segments, and strong growth in adjusted Amidst the tumult of 2017, our people earnings per share. continued to deliver for our clients, while also supporting each other.

It not only sets us apart from other professional services ﬁrms, it positions us to deliver consistently strong performance, as we did again in 2017. Behind these results are nearly 65,000 dedicated colleagues who work side by side to make a meaningful difference in critical moments — for our clients, our communities and the larger society that surrounds us. I am pleased to report the progress our ﬁrm made in 2017. 8 years OF CONSECUTIVE ADJUSTED MARGIN GROWTH IN BOTH SEGMENTS Our adjusted EPS grew 15% to $3.92, compared with $3.42 in 2016, resulting in a strong shareholder return of 22.7%. Since 2009, our adjusted EPS has grown at a compound annual growth rate of 13%. The consistency of our results during that time further sets us apart. We are among the elite 5% of S&P 500 companies with revenue over $5 billion that have grown adjusted EPS by at least 8% in each year since 2009. In our operating segments, Risk and Insurance Services revenue of $7.6 billion reﬂected an increase of 7%, or 3% on an underlying basis. Adjusted operating income rose 11% to $1.9 billion, with the adjusted margin expanding 80 basis points to 25.5%. ANOTHER YEAR OF STRONG FINANCIAL Marsh continued to generate underlying PERFORMANCE Marsh & McLennan produced excellent ﬁnancial results in 2017. We generated $14 billion in consolidated revenue for the year, an increase of 6% compared with 2016, or 3% on an underlying basis. revenue growth, with 2017 marking the seventh straight year of 3% or more. Guy Carpenter produced 4% underlying revenue growth for 2017— continuing its record of positive underlying revenue growth that started in 2009. 2 1 For a reconciliation of non-GAAP results to GAAP results, as related to all non-GAAP references presented in this letter, please refer to the Company’s Form 8-K, dated February 1, 2018, available on the Company’s website at mmc.com.

For the fourth year in a row, we fulﬁlled our two capital commitments to shareholders: 1) Increase our dividends per share by double digits; and 2) Reduce our total shares outstanding. In 2017, we returned more than $1.6 billion to our shareholders in the form of dividends and share repurchases. We reduced our share count by six million shares, or 1.1%, and increased our dividends per share by 10%. While the nature of global risks will always change, one constant is the direct relevance of the world’s top concerns to Marsh & McLennan’s expertise in risk, strategy and people. Look no further than the impact of technology. From artiﬁcial intelligence to cryptocurrencies, technology continues to transform our lives and tantalize us with its potential to solve some of the world’s biggest challenges. But with advancement comes risk. Cyber, as an example, is a man-made peril spreading faster than companies can keep up. Technological advances also create anxiety about the future of work. Digital transformation is reshaping virtually every industry. The cloud, the advent of the internet of things, advances in machine learning and faster networks are enabling our clients to realize the potential of new ideas faster than ever before, and at less cost. Imagine what will be possible, both positive and negative, when artiﬁcial intelligence and robotics become more integrated. 3 “ We are among the elite 5% of S&P 500 companies with revenue over $5 billion that have grown adjusted EPS by at least 8% in each year since 2009.” 21.2% consolidated adjusted margin — an increase of 1,240 basis points since 2007 Highest adjusted margins in Risk & Insurance Services and Consulting in 14 YEARS Risk & Insurance Services and Consulting adjusted operating income each at RECORD HIGH 10 CONSECUTIVE YEARS of consolidated adjusted margin expansion Annual revenue exceeds $14 BILLION 8 YEARS of consecutive underlying revenue growth in the 3-5 percent range 5 4 3 2 1 0 5% 5% 4% 4% 3% 3% 3% 3% 2010 2011 2012 2013 2014 2015 2016 2017 Committed more than $6 BILLION across 140+ acquisitions and investments since 2009 10% DIVIDEND GROWTH delivering on our annual commitment to increase dividends per share by double digits Clients in more than 130 COUNTRIES NEARLY 65,000 colleagues around the world making a difference for clients in critical moments “Whether issues are economic, environmental, geopolitical, cultural or technological, Marsh & McLennan is working on almost every one of them.” Embedded in the promise of technology is a human challenge. Research shows that only about a third of employees’ skills today will be relevant in the future. In addition to immediate issues like the retirement savings gap and sustainable healthcare, organizations must confront the existential challenge of reimagining their entire workforce, including how to use technology to augment, rather than replace, their greatest asset — their people. The world continues to experience powerful social and cultural changes as society evolves against a backdrop of rapid technological change and volatility. Gender equality is one such issue. Marsh & McLennan is uncovering the impediments to gender equality and highlighting the critical importance of enabling women to thrive in the workplace and beyond. We’re also contributing to the signiﬁcant research that proves when women thrive, businesses thrive. them. In a complex and volatile environment, many organizations must seek advisors to help them navigate the immediate issues of the day — and to craft the strategies that will enable their businesses to prosper well into the future. We’re pleased that many leaders are turning to Marsh & McLennan for insights and expertise on what can be achieved in an age of disruption and transformative opportunity. OUR COMMITMENT TO LONG-TERM GROWTH 2017 forced businesses, governments, organizations — and our larger society — to respond to sudden shocks and shifts. That is what Marsh & McLennan is built to do. In ways big and small, today and for the long term, everyone at Marsh & McLennan is in the business of change. Together, we help our clients realize new futures, align their workforces and make the possible practical by foreseeing and understanding the risks. With our strategic positioning centered on risk, strategy and people issues, we’ve established true differentiation. Our areas of expertise are relevant and enduring, which is a principal reason we’re able to deliver consistent results, year in and year out. Our own businesses are also being transformed by technology, new forms of capital and people. We’re always adjusting Whether issues are economic, environmental, our mix of capabilities and positioning geopolitical, cultural or technological, Marsh & ourselves in new ﬁelds with acquisitions McLennan is working on almost every one of 6 and organic investments.

In May, we announced a new alliance with Plug and Play’s Insurtech vertical, which allows us to connect our clients with top innovators in the insurtech space, helping to drive efficiency gains and growth opportunities. In our consulting businesses, emerging challenges are investment cues for us. Mercer continued to expand its capabilities in cloud-based enterprise technology in 2017 through its investment in PayScale, a cloud-based provider of compensation management and real-time salary data. This move followed Mercer’s recent acquisitions, including Thomsons Online Beneﬁts, which made us a global leader in using 7 technology to address employee beneﬁt THE POWER OF CULTURE and engagement needs; CPSG, a leading Workday services partner; and Jeitosa, a Workday implementation partner. With clients needing digital offerings to be a core part of everything a ﬁrm does, Oliver Wyman repositioned its digital, technology and analytics team (DTA) to become a powerful resource, supporting clients across industries. The team comprises more than 400 partners, consultants and specialists dedicated to helping clients develop digital We adjust our business mix all the time, which fuels our growth, but I credit our consistently strong performance in dynamic times to culture. Marsh & McLennan is a successful organization because each and every day our colleagues come to work thinking about what they can do for our clients, the problems they need to solve and how to contribute to work of which they can be proud. strategies, create new business models, Our people help our clients and society realize build applications and solve major challenges new possibilities — this is a powerful magnet through advanced analytics. Over many years we’ve reinvested in our businesses to drive growth and value. We’ll continue to put our capital to work where we see opportunities for sustained growth, for those who want to work for a purpose beyond just making more proﬁt. We attract people with heart as well as smarts, people with a social compass — people our clients want at their side when the future is at stake. whether it’s expanding our presence in We promise every person we hire three things: fast-growing economies, investing in under- work that matters, extraordinary colleagues penetrated growth segments around the and the opportunity to make a difference. world or adding new capabilities. Our colleagues like doing work the world needs — and we give them a big platform. 2017 was ﬁlled with moments where our colleagues made a meaningful difference on behalf of the clients and communities we serve. Even when perilous events directly impacted their personal lives, our colleagues put the needs of our clients ﬁrst. Shining in the moments that matter Mari Rodriguez, CEO of our brokerage in Puerto Rico, Marsh Saldaña, is just one colleague who epitomizes the resilience and dedication of our people. After Hurricane Maria hit with devastating effects, Mari and more than a hundred of her colleagues overcame signiﬁcant challenges and returned to our offices the next day. Relying on a generator for power, many worked through the weekend — with support from our global team — to ensure phones and data were restored by Monday morning so we could assist our clients. Times of peril aren’t the only times our colleagues spring into action. They’re also passionate and creative volunteers. You can see how these activities make a difference in our latest Corporate Citizenship Report, available on mmc.com. 8 “Respect for one another is fundamental at Marsh & McLennan, but real inclusion is about who is at the table, not just in the room.” Our most impactful ideas grow out of client challenges. In a company of smart people, however, ideas are the easy part. We work hard to create an environment where it’s safe to speak up, where everybody is expected to contribute and can expect to be heard — especially when their ideas are different from the conventional view. I’ve long believed that you can’t have innovation without dissent. Innovation is dissent. The colleagues I admire most are alive to the world, learning and thinking and open to new possibilities. This helps make smarter ways of doing things organic to all our lines of business. Colleagues enjoy working here because they enjoy the people with whom they work. That’s our top attraction. It makes for an unusually collaborative spirit, across business units, borders and backgrounds. And it enables us to attract other smart, creative people. Respect for one another is fundamental at Marsh & McLennan, but real inclusion is about who is at the table, not just in the room. This belief is what enables us to assemble the best talent for clients — talent that draws on a richness of diverse backgrounds and points of view to deliver superior service and solutions. Without a strong culture anchored in transparency, respect and inclusion, the greatest threats to an enterprise can come from inside. Marsh & McLennan’s policies are as clear-cut as we can make them, yet the best defense is cultural. Culture is beliefs made visible; shared beliefs and behaviors that unite us in affirmation of what we stand for as an organization. For example, whether our larger society has reached a tipping point on abuse of power in the workplace, including sexual harassment, remains to be seen — yet the global conversation that has been sparked is long overdue. What’s clear to us is that respect for every individual is fundamental at Marsh & McLennan. Each of us has a responsibility to uphold our culture, in which harassment and discrimination are not tolerated. In a complex global operating environment, our ﬁrm exists to serve our clients and put their interests ﬁrst. We do this by fostering a culture of open exchanges and constructive dissent, a culture of inclusion and respect, and a culture of doing what’s right. We call this a culture of integrity. 9 “As we look ahead, we can expect accelerating change and new challenges; we can also expect our own opportunities to grow.” LOOKING FORWARD We’re living in a time of profound transformation. Inside every historical And ﬁnally, I’d like to thank our investors for their continued support. We’re always seeking investors who support our balanced approach of delivering strong ﬁnancial performance today while investing for our future. Whatever the complexities and uncertainties of the world we live in, our ﬁrm and the work we do will be relevant and vital. As we look ahead, we can expect accelerating change and new challenges; we can also expect our own opportunities to grow. moment like this are a thousand individual These next few years will be exciting ones opportunities to make a difference: A for us, our clients and the world. Yes, it’s the problem needs a solution. A client needs an age of disruption, and it’s also the age of answer. A colleague needs help. That’s when possibility. At Marsh & McLennan, every one of Marsh & McLennan shines. We recognize us has the opportunity to make a difference. those moments when they arrive and our people rise to the occasion. We act. Best regards, I’d like to thank our colleagues for their energy and commitment as they continue to deliver for our clients and each other in moments that matter. None of us can do this alone. I’d like to thank our Board of Directors, led by Ed Hanway, our Independent Chairman, for their accountable and steadfast governance and exceptional leadership. I’d also like to thank our clients for the opportunity to earn their trust every day.

Compensation for Services in Risk and Insurance Services Marsh and Guy Carpenter are compensated for brokerage and consulting services through commissions and fees.

In addition to compensation from its clients, Marsh also receives other compensation, separate from retail fees and commissions, from insurance companies. This other compensation includes, among other things, payments for consulting and analytics services provided to insurers; fees for administrative and other services provided to or on behalf of insurers (including services relating to the administration and management of quota shares, panels and other facilities in which insurers participate); and contingent commissions, which are paid by insurers based on factors such as volume or profitability of Marsh's placements, particularly at MMA and in parts of Marsh's international operations.

For a more detailed discussion of revenue sources and factors affecting revenue in the Consulting segment, see Part II, Item 7 ("Management's Discussion and Analysis of Financial Condition and Results of Operations") of this report. REGULATION The Company's activities are subject to licensing requirements and extensive regulation under U.S. federal and state laws, as well as laws of other countries in which the Company's subsidiaries operate. See Part I, Item 1A ("Risk Factors") below for a discussion of how actions by regulatory authorities or changes in legislation and regulation in the jurisdictions in which we operate may have an adverse effect on our businesses. Risk and Insurance Services. While laws and regulations vary from location to location, every state of the United States and most foreign jurisdictions require insurance market intermediaries and related service providers (such as insurance brokers, agents and consultants, reinsurance brokers and managing general agents) to hold an individual or company license from a government agency or self-regulatory organization. Some jurisdictions issue licenses only to individual residents or locally-owned business entities; in those instances, if the Company has no licensed subsidiary, it may maintain arrangements with residents or business entities licensed to act in such jurisdiction. Such arrangements are subject to an internal review and approval process. Licensing of reinsurance intermediaries is generally less rigorous compared to that of insurance brokers, and most jurisdictions require only corporate reinsurance intermediary licenses. The Insurance Mediation Directive was adopted by the United Kingdom and 26 other European Union Member States in 2005. Its implementation gave powers to the Financial Services Authority ("FSA"), the 7 United Kingdom regulator at the time, to expand their responsibilities in line with the Financial Services and Markets Act, the result of which was the regulation of insurance and reinsurance intermediaries. The enhanced regulatory regime implemented in the United Kingdom created a licensing system based on an assessment of factors which included professional competence, financial capacity and the requirement to hold professional indemnity insurance. In April 2013, the FSA was superseded by the Financial Conduct Authority ("FCA"). In April 2014, the FCA’s responsibilities were expanded further to include the regulation of credit activities for consumers. This included the broking of premium finance to consumers who wished to spread the cost of their insurance. In April 2015, the FCA obtained concurrent competition powers enabling it to enforce prohibitions on anti-competitive behavior in relation to financial services. Insurance authorities in the United States and certain other jurisdictions in which the Company's subsidiaries do business, including the FCA in the United Kingdom, also have enacted laws and regulations governing the investment of funds, such as premiums and claims proceeds, held in a fiduciary capacity for others. These laws and regulations typically provide for segregation of these fiduciary funds and limit the types of investments that may be made with them, and generally apply to both the insurance and reinsurance business. Certain of the Company's Risk and Insurance Services activities are governed by other regulatory bodies, such as investment, securities and futures licensing authorities. In the United States, Marsh and Guy Carpenter use the services of MMC Securities LLC, a SEC registered broker-dealer in the United States, investment adviser and introducing broker. MMC Securities LLC is a member of the Financial Industry Regulatory Authority ("FINRA"), the National Futures Association and the Securities Investor Protection Corporation ("SIPC"), primarily in connection with capital markets and other investment banking-related services relating to insurance-linked and alternative risk financing transactions. Also in the United States, Marsh uses the services of MMA Securities LLC, a SEC registered broker-dealer and member of FINRA, SIPC and the Municipal Securities Rulemaking Board, primarily in connection with retirement, executive compensation and benefits consulting and advisory services to qualified and non-qualified benefits plans, companies and executives. In the United Kingdom, Marsh and Guy Carpenter use the expertise of MMC Securities (Europe) Limited, which is authorized and regulated by the FCA to provide advice on securities and investments, including mergers & acquisitions in the European Union. MMC Securities LLC, MMC Securities (Europe) Limited and MMA Securities LLC are indirect, wholly-owned subsidiaries of Marsh & McLennan Companies, Inc. Consulting. Certain of Mercer's retirement-related consulting and investment services are subject to pension law and financial regulation in many countries. In addition, the trustee services, investment services (including advice to persons, institutions and other entities on the investment of pension assets and assumption of discretionary investment management responsibilities) and retirement and employee benefit program administrative services provided by Mercer and its subsidiaries and affiliates are also subject to investment and securities regulations in various jurisdictions, including regulations imposed or enforced by the SEC and the Department of Labor in the United States, the FCA in the United Kingdom, the Central Bank of Ireland and the Australian Prudential Regulation Authority and the Australian Securities and Investments Commission. In the United States, Mercer provides investment services through Mercer Investment Management, Inc. and Mercer Investment Consulting LLC, each an SEC- registered investment adviser in the United States. Mercer Trust Company, a New Hampshire chartered trust bank, provides services for Mercer’s benefits administration and investment management business in the United States. The benefits insurance consulting and brokerage services provided by Mercer and its subsidiaries and affiliates are subject to the same licensing requirements and regulatory oversight as the insurance market intermediaries described above regarding our Risk and Insurance Services businesses. Mercer uses the services of MMC Securities LLC to provide certain retirement and employee benefit services. Oliver Wyman Group uses the services of MMC Securities (Europe) Limited in the European Union, primarily in connection with corporate finance advisory services. FATCA. Regulations promulgated by the U.S. Treasury Department pursuant to the Foreign Account Tax Compliance Act and related legislation (FATCA) require the Company to take various measures relating to non-U.S. funds, transactions and accounts. The regulations impose on Mercer certain client financial account tracking and disclosure obligations with respect to non-U.S. financial institution and insurance clients, and require Marsh and Guy Carpenter (and Mercer, in limited circumstances) to collect, validate and maintain certain documentation from each foreign insurance entity that insures a risk that is subject 8 to the regulations. As of January 1, 2017, FATCA expanded to regulate a broader set of insurance and reinsurance placements, known as "foreign-to-foreign" transactions. The Company has adopted processes to substantially address FATCA’s requirements. COMPETITIVE CONDITIONS The Company faces strong competition in all of its businesses from providers of similar products and services, including competition with regard to identifying and pursuing acquisition candidates. The Company also encounters strong competition throughout its businesses from both public corporations and private firms in attracting and retaining qualified employees. In addition to the discussion below, see "Risks Relating to the Company Generally — Competitive Risks," in Part I, Item 1A of this report. Risk and Insurance Services. The Company's combined insurance and reinsurance services businesses are global in scope. Our insurance and reinsurance businesses compete principally on sophistication, range, quality and cost of the services and products they offer to clients. The Company encounters strong competition from other insurance and reinsurance brokerage firms that operate on a global, regional, national or local scale, from a large number of regional and local firms in the United States, the European Union and elsewhere, from insurance and reinsurance companies that market, distribute and service their insurance and reinsurance products without the assistance of brokers or agents and from other businesses, including commercial and investment banks, accounting firms, consultants and online platforms, that provide risk-related services and products or alternatives to traditional insurance brokerage services. In addition, third party capital providers have entered the insurance and reinsurance risk transfer market offering products and capital directly to the Company’s clients. Their presence in the market increases the competitive pressures that the Company faces. Certain insureds and groups of insureds have established programs of self insurance (including captive insurance companies) as a supplement or alternative to third-party insurance, thereby reducing in some cases their need for insurance placements. Certain insureds also obtain coverage directly from insurance providers. There are also many other providers of managing general agency, affinity programs and private client services, including specialized firms, insurance companies and other institutions. Consulting. The Company's consulting businesses face strong competition from other privately and publicly held worldwide and national companies, as well as regional and local firms. These businesses generally compete on the basis of the range, quality and cost of the services and products they provide to clients. Competitors include independent consulting and outsourcing firms, as well as consulting and outsourcing operations affiliated with accounting, information systems, technology and financial services firms. Mercer's investments business faces competition from many sources, including investment consulting firms (many of which offer delegated services) and other financial institutions. In some cases, clients have the option of handling the services provided by Mercer and Oliver Wyman Group internally, without assistance from outside advisors. Segmentation of Activity by Type of Service and Geographic Area of Operation. Financial information relating to the types of services provided by the Company and the geographic areas of its operations is incorporated herein by reference to Note 15 to the consolidated financial statements included under Part II, Item 8 of this report.

RISKS RELATING TO THE COMPANY GENERALLY Legal and Regulatory Risks We are subject to significant uninsured exposures arising from errors and omissions, breach of fiduciary duty and other claims. Our operating companies provide numerous professional services, including the placement of insurance and the provision of consulting, investment advisory and actuarial services, to clients around the world. As a result, the Company and its subsidiaries are subject to a significant number of errors and omissions, breach of fiduciary duty and similar claims, which we refer to collectively as "E&O claims." In our Risk and Insurance Services segment, such claims include allegations of damages arising from our failure to assess clients’ risks, advise clients, place coverage or notify insurers of potential claims on behalf of clients in accordance with our obligations to them. In our Consulting segment, where we increasingly act in a fiduciary capacity through our investments business, such claims include allegations of damages arising from the provision of consulting, investments, actuarial, pension administration and other services. These services frequently involve complex calculations and other analysis, including (i) making assumptions about, and preparing estimates concerning, contingent future events, (ii) drafting and interpreting complex documentation governing pension plans, (iii) calculating benefits within complex pension structures, (iv) providing investment advice, including guidance on asset allocation and investment strategy, and (v) managing client assets, including the selection of investment managers. These matters often relate to services provided by the Company dating back many years. Such claims may subject us to significant liability for monetary damages, including punitive and treble damages, negative publicity and reputational harm, and may divert personnel and management resources. We may be unable to effectively limit our potential liability in certain jurisdictions, including through insurance, or in connection with certain types of claims, particularly those concerning claims of a breach of fiduciary duty. In establishing liabilities for E&O claims under generally accepted accounting principles (“GAAP”), the Company uses case level reviews by inside and outside counsel, actuarial analysis by Oliver Wyman Group, a subsidiary of the Company, and other methods to estimate potential losses. A liability is established when a loss is both probable and reasonably estimable. The liability is assessed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable. Given the challenges inherent in establishing liabilities in accordance with GAAP, as well as the unpredictability of E&O claims and the litigation that can flow from them, it is possible that an adverse outcome in a particular matter could have a material adverse effect on the Company's business, results of operations or financial condition in a given quarterly or annual period. We are subject to regulatory investigations, reviews and other inquiries that consume significant management time and, if determined unfavorably to us, could have a material adverse effect on our business, results of operations or financial condition. We are subject to regulatory investigations, reviews and other inquiries that consume significant management time and, if determined unfavorably to us, could have a material adverse effect on our business, results of operations or financial condition. For example, in 2017 we received notices related to four separate regulatory matters in Europe. In October 2017, the Company received a notice that the Directorate-General for Competition of the European Commission had commenced a civil investigation of a number of insurance brokers, including Marsh, regarding "the exchange of commercially sensitive information between competitors in relation to aviation and aerospace insurance and reinsurance broking products and services in the European Economic Area, as well as possible coordination between competitors." In June 2017, the FCA issued a final report in connection with a market study of the U.K. asset management industry, which includes asset managers and investment consultants, including 12 Mercer. Following the report, in September 2017, the FCA announced its decision to refer the investment consulting and fiduciary management markets to the U.K. Competition & Markets Authority (the "CMA") for a market investigation. In July 2017, the Directorate-General for Competition of the European Commission together with the Irish Competition and Consumer Protection Commission conducted on-site inspections at the offices of Marsh and other industry participants in Dublin in connection with an investigation regarding the "possible participation in anticompetitive agreements and/or concerted practices contrary to [E.U. competition law] in the market for commercial motor insurance in the Republic of Ireland." In November 2017, the FCA announced the terms of reference for a market study concerning the wholesale insurance broker sector in the United Kingdom to assess "how effective competition is working in the wholesale insurance broker sector” and “how brokers influence competition in the underwriting sector." These regulatory matters are at early stages and we are unable to predict their likely timing, outcome or ultimate impact. Additional information regarding these investigations and certain other legal and regulatory proceedings is set forth in Note 14 to our consolidated financial statements included under Part II, Item 8 of this report. We cannot guarantee that we are or will be in compliance with all current and potentially applicable U.S. federal and state or foreign laws and regulations, and actions by regulatory authorities or changes in legislation and regulation in the jurisdictions in which we operate could have a material adverse effect on our business. Our activities are subject to extensive regulation under the laws of the United States and its various states, the United Kingdom, the European Union and its member states and the other jurisdictions in which we operate. For example, we are subject to regulation by agencies such as the Securities and Exchange Commission, FINRA and state insurance regulators in the United States, the FCA and the Competition and Markets Authority (CMA) in the United Kingdom, and the European Commission in the European Union, as further described above under Part I, Item 1 - Business (Regulation) of this report. We are also subject to trade sanctions laws relating to countries such as Cuba, Iran, Russia, Sudan and Syria, and anti-corruption laws such as the U.S. Foreign Corrupt Practices Act and the U.K. Anti-Bribery Act. We are subject to numerous other laws on matters as diverse as internal control over financial reporting and disclosure controls and procedures, securities regulation, data privacy and protection, taxation, anti-trust and competition, immigration, wage-and-hour standards and employment and labor relations. The U.S. and foreign laws and regulations that apply to our operations are complex and may change rapidly, and our efforts to comply and keep up with them require significant resources. In some cases, these laws and regulations may decrease the need for our services, increase our costs, negatively impact our revenues or impose operational limitations on our business, including on the products and services we may offer or on the amount or type of compensation we may collect. While we attempt to comply with applicable laws and regulations, there can be no assurance that we, our employees, our consultants and our contractors and other agents are in full compliance with such laws and regulations or interpretations at all times, or that we will be able to comply with any future laws or regulations. If we fail to comply or are accused of failing to comply with applicable laws and regulations, including those referred to above, we may become subject to investigations, criminal penalties, civil remedies or other consequences, including fines, injunctions, loss of an operating license or approval, increased scrutiny or oversight by regulatory authorities, the suspension of individual employees, limitations on engaging in a particular business or redress to clients or other parties, and may become exposed to negative publicity or reputational damage. Moreover, our failure to comply with laws or regulations in one jurisdiction may result in increased regulatory scrutiny by other regulatory agencies in that jurisdiction or regulatory agencies in other jurisdictions. The cost of compliance and the consequences of failing to be in compliance could therefore have a material adverse effect on our business, results of operations and financial condition. In most jurisdictions, government regulatory authorities have the power to interpret and amend or repeal applicable laws and regulations, and have discretion to grant, renew and revoke the various licenses and approvals we need to conduct our activities. Such authorities may require the Company to incur substantial costs in order to comply with such laws and regulations. In some areas of our businesses, we act on the basis of our own or the industry's interpretations of applicable laws or regulations, which may conflict from state to state or country to country. In the event those interpretations eventually prove 13 different from the interpretations of regulatory authorities, we may be penalized or precluded from carrying on our previous activities. Moreover, the laws and regulations to which we are subject may conflict among the various jurisdictions and countries in which we operate, which increases the likelihood of our businesses being non-compliant in one or more jurisdictions. Cybersecurity and Data Protection Risks We could incur significant liability or our reputation could be damaged if our information systems are breached or we otherwise fail to protect client or Company data or information systems. We rely on the efficient, uninterrupted and secure operation of complex information technology systems and networks to operate our business and securely process, transmit and store electronic information. In the normal course of business, we also share electronic information with our vendors and other third parties. This electronic information comprises sensitive and confidential data, including information related to financial records, health care, mergers and acquisitions and clients’ personal data. Our information technology systems and safety control systems, and those of our numerous third-party providers, are potentially vulnerable to damage or interruption from a variety of external threats, including cyber-attacks, computer viruses and other malware, ransomware and other types of data and systems related incidents. Our systems are also subject to compromise from internal threats such as improper action by employees, vendors and other third parties with otherwise legitimate access to our systems. Moreover, we face the ongoing challenge of managing access controls in a complex environment. The latency of a compromise is often measured in months but could be years, and we may not be able to detect a compromise in a timely manner. We could experience significant financial and reputational harm if our information systems are breached, sensitive client or Company data are compromised, surreptitiously modified, rendered inaccessible for any period of time or maliciously made public, or if we fail to make adequate disclosures to the public or law enforcement agencies following any such event. We are at risk of attack by a growing list of adversaries, including state-sponsored organizations, organized crime, hackers or "hactivists" (activist hackers), through use of increasingly sophisticated methods of attack, including long-term, persistent attacks referred to as advanced persistent threats. Because the techniques used to obtain unauthorized access or sabotage systems change frequently and generally are not identified until they are launched against a target, we may be unable to anticipate these techniques or implement adequate preventative measures, resulting in potential data loss or other damage to information technology systems. As the breadth and complexity of the technologies we use continue to grow, including as a result of the use of mobile devices, cloud services, social media and the increased reliance on devices connected to the Internet (known as the "Internet of Things"), the potential risk of security breaches and cyber-attacks also increases. Despite ongoing efforts to improve our ability to protect data from compromise, we may not be able to protect all of our data across our diverse systems. Should an attacker gain access to our network using compromised credentials of an authorized user, we are at risk that the attacker might successfully leverage that access to compromise additional systems and data. Certain measures that could increase the security of our systems, such as data encryption or deployment of multi-factor authentication, take significant time and resources to deploy broadly, and such measures may not be effective against an attack. The inability to implement, maintain and upgrade adequate safeguards could have a material adverse effect on our business. Our information systems must be continually updated, patched, and upgraded to protect against known vulnerabilities. The volume of new software vulnerabilities has increased markedly, as has the criticality of patches and other remedial measures. In addition to remediating newly identified vulnerabilities previously identified vulnerabilities must also be continuously addressed. Accordingly, we are at risk that cyber attackers exploit these known vulnerabilities before they have been addressed. Due to the large number and age of the systems and platforms that we operate, the increased frequency at which vendors are issuing security patches to their products, the need to test patches and, in some cases coordinate with clients and vendors, before they can be deployed, we perpetually face the substantial risk that we cannot deploy patches in a timely manner. We are also dependent on third party vendors to keep their systems patched and secure in order to protect our data. Any failure related to these activities could have a material adverse effect on our business. 14 We have numerous vendors and other third parties who receive personal information from us in connection with the services we offer our clients. In addition, we have migrated certain data, and may increasingly migrate data, to the cloud hosted by third-party providers. Some of these vendors and third parties also have direct access to our systems. We are at risk of a cyber-attack involving a vendor or other third party, which could result in a breakdown of such third party’s data protection processes or the cyber-attackers gaining access to our infrastructure through the third party. To the extent that a vendor or third party suffers a cyber-attack that compromises its operations, we could incur significant costs and possible service interruption, which could have an adverse effect on our business. We have a history of making acquisitions and investments, including 111 in the period from 2012-2017. The process of integrating the information systems of the businesses we acquire is complex and exposes us to additional risk. For instance, we may not adequately identify weaknesses in an acquired entity’s information systems, either before or after the acquisition, which could affect the value we are able to derive from the acquisition, expose us to unexpected liabilities or make our own systems more vulnerable to a cyber-attack. We may also be unable to integrate the systems of the businesses we acquire into our environment in a timely manner, which could further increase these risks until such integration takes place. Our policies, employee training (including phishing prevention training), procedures and technical safeguards may be insufficient to prevent or detect improper access to confidential, personal or proprietary information by employees, vendors or other third parties with otherwise legitimate access to our systems. Improper access to or disclosure of sensitive client or Company information could harm our reputation and subject us to liability under our contracts, as well as under existing or future laws, rules and regulations. We have from time to time experienced data incidents and cybersecurity breaches, such as malware incursions (including computer viruses and ransomware), users exceeding their data access authorization, employee misconduct and incidents resulting from human error, such as loss of portable and other data storage devices. Like many companies, we are subject to regular phishing email campaigns directed at our employees that can result in malware infections and data losses. Although these incidents have resulted in data loss and other damages, to date, they have not had a material adverse effect on our business or operations. In the future, these types of incidents could result in confidential, personal or proprietary information being lost or stolen, surreptitiously modified, rendered inaccessible for any period of time, or maliciously made public, including client, employee or company data, which could have a material adverse effect on our business. In the event of a cyber-attack, we might have to take our systems offline, which could interfere with services to our clients or damage our reputation. We also may be unable to detect an incident, assess its severity or impact, or appropriately respond in a timely manner. In addition, our liability insurance, which includes cyber insurance, may not be sufficient in type or amount to cover us against claims related to security breaches, cyber-attacks and other related data and system incidents. The costs to comply with, or our failure to comply with, U.S. and foreign laws related to privacy, data security and data protection, such as the E.U. General Data Protection Regulation, could adversely affect our financial condition, operating results and our reputation. In operating our business and providing services and solutions to clients, we store and transfer sensitive employee and client data, including personal data, in and across multiple jurisdictions. We leverage systems and applications that are spread all over the world requiring us to regularly move data across national borders. As a result, we are subject to a variety of laws and regulations in the United States, Europe and around the world regarding privacy, data protection and data security. These laws and regulations are continuously evolving and developing. In particular, the number of high-profile security breaches at major companies continues to accelerate, which will likely lead to even greater regulatory scrutiny. The scope and interpretation of the laws that are or may be applicable to us are often uncertain and may be conflicting, particularly with respect to foreign laws. For example, the E.U. General Data Protection Regulation ("GDPR"), which becomes effective in May 2018, greatly increases the European Commission’s jurisdictional reach of its laws and adds a broad array of requirements for handling personal data, such as the public disclosure of data breaches, privacy impact assessments, data 15 portability and the appointment of data protection officers in some cases. Other countries around the world, including China, Japan, Australia and Singapore, have recently adopted sweeping new data protection laws, or are enacting data localization laws that require data to stay within their borders. At a state level, the New York State Department of Financial Services, by way of example, has issued cybersecurity regulations which impose an array of detailed security measures on covered entities. All of these evolving compliance and operational requirements impose significant costs that are likely to increase over time, may divert resources from other initiatives and projects and could restrict the way services involving data are offered, all of which may adversely affect our results of operations. Furthermore, enforcement actions and investigations by regulatory authorities related to data security incidents and privacy violations continue to increase. Unauthorized disclosure or transfer of sensitive or confidential client or Company data, whether through systems failure, employee negligence, fraud or misappropriation, by the Company, our vendors or other parties with whom we do business could subject us to significant litigation, monetary damages, regulatory enforcement actions, fines and criminal prosecution in one or more jurisdictions. For example, under the GDPR, violations could result in a fine of up to 4% of a corporation’s global annual revenue. Competitive Risks Our business performance and growth plans could be negatively affected if we are not able to respond effectively to the threat of digital disruption and other technological change. To remain competitive in many of our business areas, we must anticipate and respond effectively to the threat of digital disruption and other technological change. The threat comes from traditional players, such as insurers, through disintermediation as well as from new entrants, such as technology companies, "Insurtech" start-up companies and others. These players are focused on using technology and innovation, including artificial intelligence (AI) and blockchain, to simplify and improve the customer experience, increase efficiencies, alter business models and effect other potentially disruptive changes in the industries in which we operate. In order to maintain a competitive position, we must continue to invest in new technologies and new ways to deliver our products and services. We have a number of strategic initiatives involving investments in technology systems and infrastructure to support our growth strategy. These investments may not be profitable or may be less profitable than what we have experienced historically. In some cases, we depend on key vendors and partners to provide technology and other support for our strategic initiatives. If these vendors or partners fail to perform their obligations or otherwise cease to work with us, our ability to execute on our strategic initiatives could be adversely affected. If we do not keep up with technological changes or execute well on our strategic initiatives, our business and results of operations could be adversely impacted. Failure to maintain our corporate culture or damage to our reputation could have a material adverse effect on our business. We strive to create a culture in which our colleagues act with integrity and respect and feel comfortable speaking up to report instances of misconduct. We are a people business, and our ability to attract and retain employees and clients is highly dependent upon our commitment to a diverse and inclusive workplace, our level of service, trustworthiness, ethical business practices and other qualities. Our colleagues are the cornerstone of this culture, and acts of misconduct by any employee, and particularly by senior management, could erode trust and confidence and damage our reputation among existing and potential clients and other stakeholders. Negative public opinion could result from actual or alleged conduct by us or those currently or formerly associated with us in any number of activities or circumstances, including operations, employment related offenses such as sexual harassment and discrimination, regulatory compliance, and the use and protection of data and systems, satisfaction of client expectations, and from actions taken by regulators or others in response to such conduct. This damage to our reputation could affect the confidence of our clients, rating agencies, regulators, stockholders and the other parties in a wide range of transactions that are important to our business and could have a material adverse effect on our business, financial condition and operating results. 16 The loss of members of our senior management team or other key colleagues could have a material adverse effect on our business. We rely upon the contributions of our senior management team to establish and implement our business strategy and to manage the future growth of our business. The loss of any of the senior management team could limit our ability to successfully execute our business strategy or adversely affect our ability to retain existing and attract new clients. Moreover, we could be adversely affected if we fail to adequately plan for the succession of members of our senior management team. Across all of our businesses, our colleagues are critical to developing and retaining the client relationships as well as performing the services on which our revenues are earned. It is therefore important for us to attract, incentivize and retain significant revenue-producing employees and the key managerial and other professionals who support them. We face numerous challenges in this regard, including the intense competition for talent and the general mobility of colleagues. Losing colleagues who manage or support substantial client relationships or possess substantial experience or expertise could adversely affect our ability to secure and complete client engagements, which could adversely affect our results of operations. And, subject to applicable enforceable restrictive covenants, if a key employee were to join an existing competitor or form a competing company, some of our clients could choose to use the services of that competitor instead of our services. We face significant competitive pressures in each of our businesses, including from disintermediation. As a global professional services firm, the Company faces intense, sustained competition in each of its businesses, and the competitive landscape continues to change and evolve. Our ability to compete successfully depends on a variety of factors, including the quality and expertise of our colleagues, our geographic reach, the sophistication and quality of our services, our pricing relative to competitors, our customers' ability to self-insure or use internal resources instead of consultants, and our ability to respond to changes in client demand and industry conditions. Some of our competitors may have greater financial resources, or may be better positioned to respond to technological and other changes in the industries we serve, and they may be able to compete more effectively. If we are unable to respond successfully to the changing conditions we face, our businesses, results of operations and financial condition will be adversely impacted. In our Risk and Insurance Services segment, in addition to the challenges posed by capital market alternatives to traditional insurance and reinsurance, we compete intensely against a wide range of other insurance and reinsurance brokerage and risk advisory firms that operate on a global, regional, national or local scale for both client business and employee talent. We also compete with insurance and reinsurance companies that market and service their insurance products directly to consumers and without the assistance of brokers or other market intermediaries, and with various other companies that provide risk-related services or alternatives to traditional brokerage services, including those that rely almost exclusively on technological solutions or platforms. This competition is intensified by an industry trend toward a "syndicated" or "distributed" approach to the purchase of insurance and reinsurance brokerage services, where a client engages multiple brokers to service different portions of the client's account. In addition, third party capital providers have entered the insurance and reinsurance risk transfer market offering products and capital directly to our clients. In our Consulting segment, we compete for business with numerous consulting firms and similar organizations, many of whom also provide, or are affiliated with firms that provided, accounting, information systems, technology and financial services. Such competitors may be able to offer more comprehensive products and services to potential clients, which may give them a competitive advantage. Consolidation in the industries we serve could adversely affect our business. Companies in the industries that we serve may seek to achieve economies of scale and other synergies by combining with or acquiring other companies. If two or more of our current clients merge, or consolidate or combine their operations, it may decrease the amount of work that we perform for these clients. If one of our current clients merges or consolidates with a company that relies on another provider for its services, we may lose work from that client or lose the opportunity to gain additional work. Any of these or similar possible results of industry consolidation could adversely affect our business. The 17 insurance industry continued to see robust market consolidation in 2017, and this trend could continue or accelerate in 2018. As insurance and reinsurance companies continue to consolidate, Guy Carpenter’s smaller client base may be more susceptible to this risk given the limited number of insurance company clients and reinsurers in the marketplace. We rely on a large number of vendors and other third parties to perform key functions of our business operations and to provide services to our clients. These vendors and third parties may act in ways that could harm our business. We rely on a large number of vendors and other third parties, and in some cases subcontractors, to provide services, data and information such as technology, information security, funds transfers, data processing, and administration and support functions that are critical to the operations of our business. These third parties include correspondents, agents and other brokers and intermediaries, insurance markets, data providers, plan trustees, payroll service providers, software and system vendors, health plan providers, investment managers, risk modeling providers, outsourced providers of client-related services and providers of human resource functions, such as recruiters. As we do not fully control the actions of these third parties, we are subject to the risk that their decisions or operations may adversely impact us and replacing these service providers could create significant delay and expense. A failure by the third parties to comply with service level agreement, or regulatory or legal requirements in a high quality and timely manner, particularly during periods of our peak demand for their services, could result in economic and reputational harm to us. In addition, these third parties face their own technology, operating, business and economic risks, and any significant failures by them, including the improper use or disclosure of our confidential client, employee, or company information or failure to comply with applicable law, could cause harm to our reputation or otherwise expose us to liability. An interruption in or the cessation of service by any service provider as a result of systems failures, capacity constraints, financial difficulties or for any other reason could disrupt our operations, impact our ability to offer certain products and services, and result in contractual or regulatory penalties, liability claims from clients or employees, damage to our reputation and harm to our business. Business Resiliency Risks Our inability to successfully recover should we experience a disaster or other business continuity problem could cause material financial loss, loss of human capital, regulatory actions, reputational harm or legal liability. If we experience a local or regional disaster or other business continuity event, such as an earthquake, hurricane, flood, terrorist attack, pandemic, security breach, cyber-attack, power loss or telecommunications failure, our ability to operate will depend, in part, on the continued availability of our personnel, our office facilities and the proper functioning of our computer, telecommunication and other related systems and operations. In such an event, we could experience operational challenges that could have a material adverse effect on our business. The risk of business disruption is more pronounced in certain geographic areas, including major metropolitan centers, like New York or London, where we have significant operations and approximately 3,500 colleagues in each location, and in certain countries and regions in which we operate that are subject to higher potential threat of terrorist attacks or military conflicts. Our operations depend in particular upon our ability to protect our technology infrastructure against damage. If a business continuity event occurs, we could lose client or Company data or experience interruptions to our operations or delivery of services to our clients, which could have a material adverse effect. A cyber-attack or other business continuity event affecting us or a key vendor or other third party could result in a significant and extended disruption in the functioning of our information technology systems or operations, requiring us to incur significant expense to address and remediate or otherwise resolve such issues. For example, hackers have increasingly targeted companies by attacking internet- connected industrial control and safety control systems. An extended outage could result in the loss of clients and a decline in our revenues. We regularly assess and take steps to improve our existing business continuity plans and key management succession. However, a disaster or other continuity event on a significant scale or affecting certain of our key operating areas within or across regions, or our inability to successfully recover from such an event, could materially interrupt our business operations and result in material financial loss, loss 18 of human capital, regulatory actions, reputational harm, damaged client relationships and legal liability. Our business disruption insurance may also not fully cover, in type or amount, the cost of a successful recovery in the event of such a disruption. Financial Risks The impacts from recently-passed U.S. federal tax reform remain uncertain. On December 22, 2017, President Trump signed into law the tax legislation commonly known as the "Tax Cuts and Jobs Act" (the "TCJA") that significantly changes the U.S. Internal Revenue Code of 1986, as amended. The TCJA, which generally became effective on January 1, 2018, revises the U.S. tax code by, among other things, lowering the corporate income tax rate from 35% to 21%, limiting deductibility of interest expense and implementing a broadly territorial tax system. The TCJA also imposes a one-time repatriation tax on deemed repatriated earnings of foreign subsidiaries. While the TCJA is expected to have a favorable impact on our overall effective tax rate as reported under generally accepted accounting principles both in the first fiscal quarter of 2018 and subsequent reporting periods, the legislation also resulted in aggregate provisional tax charges in the fourth quarter of 2017 of approximately $460 million, primarily related to the re-measurement of the net U.S. deferred tax asset and the deemed repatriation tax. The TCJA was enacted late in 2017 and limited implementation guidance was provided. As clarified by the SEC in Staff Accounting Bulletin No. 118, we made provisional estimates of the deemed repatriation tax impact. Moreover, certain provisions of the TCJA, such as the Base Erosion and Anti-Abuse Tax and the Global Intangible Low-Tax Income ("GILTI") provision and any adverse impacts from new guidance on the implementation of the TCJA may create new pressure on our effective tax rate in future periods. It is also currently unknown if and to what extent various states will conform to the TCJA and the impact such changes in state-tax law may have. The estimated impacts of the new law are based on our current knowledge and assumptions, and therefore the ultimate impacts remain uncertain. Given the significant complexity of the TCJA, anticipated guidance from the U.S. Treasury about implementing the TCJA, and the potential for new legislation or additional guidance from the Securities and Exchange Commission, the Financial Accounting Standards Board or other regulatory authorities related to the TCJA, recognized impacts in future periods could be significantly different from our current estimates. Such uncertainty may also result in increased scrutiny from, or disagreements with, tax authorities. Our results of operations could be adversely affected by macroeconomic conditions, political events and market conditions. Macroeconomic conditions, political events and other market conditions around the world affect our clients' businesses and the markets they serve. These conditions may reduce demand for our services or depress pricing for those services, which could have a material adverse effect on our results of operations. Changes in macroeconomic and political conditions could also shift demand to services for which we do not have a competitive advantage, and this could negatively affect the amount of business that we are able to obtain. For example, recently there has been a move toward protectionist laws and business practices in some countries, which could favor local competition and adversely affect our business. In particular, the United Kingdom’s pending exit from the European Union, referred to as "Brexit," continues to create political and economic uncertainty, particularly in the United Kingdom and the E.U., and this uncertainty may last for years. Our business in the United Kingdom, the E.U. and worldwide could be affected during this period of uncertainty, and perhaps longer, by the impact of the United Kingdom’s referendum. If the demand for our products and services declines as a result of these or any other macroeconomic conditions, political events or market conditions, we may be required to respond in a way which could adversely affect our ability to execute our business strategy. Our investments, including our minority investments in other companies as well as our cash investments and those held in a fiduciary capacity, are subject to general credit, liquidity, counterparty, foreign exchange, market and interest rate risks. These risks may be exacerbated by global macroeconomic conditions, market volatility and regulatory, financial and other difficulties affecting the companies in which we have invested or that may be faced by financial institution counterparties. During times of stress in the banking industry, counterparty risk can quickly escalate, potentially resulting in substantial trading and investment losses for corporate and other investors. In addition, we may incur investment losses as a 19 result of unusual and unpredictable market developments, and we may continue to experience reduced investment earnings if the yields on investments deemed to be low risk remain at or near their current low levels. If the banking system or the fixed income, interest rate, credit or equity markets deteriorate, the value and liquidity of our investments could be adversely affected. Finally, the value of the Company's assets held in other jurisdictions, including cash holdings, may decline due to foreign exchange fluctuations. If we are unable to collect our receivables, our results of operations and cash flows could be adversely affected. Our business depends on our ability to obtain payment from our clients of the amounts they owe us for the work we perform. As of December 31, 2017, our receivables for our commissions and fees were approximately $3.8 billion, or approximately one-quarter of our total annual revenues. Macroeconomic or political conditions could result in financial difficulties for our clients, which could cause clients to delay payments to us, request modifications to their payment arrangements that could increase our receivables balance or default on their payment obligations to us. In addition, if we experience an increase in the time it takes to bill and collect for our services, our cash flows could be adversely affected. We may not be able to obtain sufficient financing on favorable terms. The maintenance and growth of our business, the payment of dividends and our ability to make share repurchases rely on our access to capital, which depends in large part on cash flow generated by our business and the availability of equity and debt financing. Certain of our businesses such as GC Securities and MMC Securities (Europe) Limited also rely on financings by us to fund debt and equity capital raising offerings by their clients. There can be no assurance that our operations will generate sufficient positive cash flow to finance all of our capital needs or that we will be able to obtain equity or debt financing on favorable terms. In addition, our ability to obtain financing will depend in part upon prevailing conditions in credit and capital markets, which are beyond our control. Our defined benefit pension plan obligations could cause the Company's financial position, earnings and cash flows to fluctuate. Our defined benefit pension obligations and the assets set aside to fund those obligations are sensitive to certain changes in the financial markets. Any such changes may result in increased pension expense or additional cash payments to fund these plans. The Company has significant defined benefit pension obligations to its current and former employees, totaling approximately $16.3 billion, and related plan assets of approximately $16.2 billion, at December 31, 2017 on a U.S. GAAP basis. The Company's policy for funding its defined benefit pension plans is to contribute amounts at least sufficient to meet the funding requirements set forth by law. In the United States, contributions to these plans are based on ERISA guidelines. Outside the United States, contributions are generally based on statutory requirements and local funding practices, which may differ from measurements under U.S. GAAP. In the U.K., for example, the assumptions used to determine pension contributions are the result of legally-prescribed negotiations between the Company and the plans' trustee. Currently, the use of these assumptions results in a lower funded status than determined under U.S. GAAP and may result in contributions irrespective of the U.S. GAAP funded status. The financial calculations relating to our defined benefit pension plans are complex. Pension plan assets could decrease as the result of poor future asset performance. Also, pension plan liabilities, periodic pension expense and future funding amounts could increase as a result of a decline in the interest rates we use to discount our pension liabilities, longer lifespans than those reflected in our mortality assumptions, actual investment return that is less than the expected return on assets, adverse changes in laws or regulations and other variables. While we have taken steps to mitigate the impact of pension volatility on our earnings and cash funding requirements, these strategies may not be successful. Accordingly, given the magnitude of our worldwide pension plans, variations in or reassessment of the preceding or other factors or potential miscalculations relating to our defined benefit pension plans could cause significant fluctuation from year to year in our earnings and cash flow, as well as our pension plan assets, liabilities and equity, and may result in increased levels of contributions to our pension plans. 20 Our significant non-U.S. operations expose us to exchange rate fluctuations and various risks that could impact our business. A significant portion of our business is located outside of the United States. We are subject to exchange rate movement because we must translate the financial results of our foreign subsidiaries into U.S. dollars and also because some of our subsidiaries receive revenue other than in their functional currencies. Exchange rate movements may change over time, and they could have a material adverse impact on our financial results and cash flows reported in U.S. dollars. Our U.S. operations earn revenue and incur expenses primarily in U.S. dollars. In certain jurisdictions, however, our Risk and Insurance Services operations generate revenue in a number of different currencies, but expenses are almost entirely incurred in local currency. Due to fluctuations in foreign exchange rates, we are subject to economic exposure as well as currency translation exposure on the net operating results of our operations. Because the non-U.S. based revenue that is exposed to foreign exchange fluctuations is approximately 50% of total revenue, exchange rate movement can have a significant impact on our business, financial condition, results of operations and cash flow. For additional discussion, see "Market Risk and Credit Risk-Foreign Currency Risk" in Part II, Item 7A ("Quantitative and Qualitative Disclosures about Market Risk") of this report. We may not be able to receive dividends or other distributions in needed amounts from our subsidiaries. The Company is organized as a legal entity separate and distinct from our operating subsidiaries. Because we do not have significant operations of our own, we are dependent upon dividends and other payments from our operating subsidiaries to meet our obligations for paying principal and interest on outstanding debt obligations, paying dividends to stockholders, repurchasing our common stock under our share repurchase program and paying corporate expenses. In the event our operating subsidiaries are unable to pay sufficient dividends and make other payments to the Company, we may not be able to service our debt, pay dividends on or repurchase our common stock or meet our other obligations. Further, the Company derives a significant portion of its revenue and operating profit from operating subsidiaries located outside the United States. Funds from the current year’s earnings of the Company's non-U.S. operating subsidiaries are regularly repatriated to the United States. A number of factors could arise that could limit our ability to repatriate funds or could make repatriation cost-prohibitive, including, but not limited to, the imposition of currency controls and other government restrictions on repatriation in the jurisdictions in which our subsidiaries operate, fluctuations in foreign exchange rates and the imposition of withholding and other taxes on such payments. In the event we are unable to generate or repatriate cash from our operating subsidiaries, our overall liquidity could deteriorate and our ability to finance our obligations, including to pay dividends on or repurchase our common stock, could be adversely affected. Our quarterly revenues and profitability may fluctuate significantly. Quarterly variations in revenues and operating results may occur due to several factors. These include: • • • • • • • the number of client engagements during a quarter; the possibility that clients may decide to delay or terminate a current or anticipated project as a result of factors unrelated to our work product or progress; fluctuations in hiring and utilization rates and clients' ability to terminate engagements without penalty; the impact of changes in accounting standards or in our accounting estimates or assumptions, including from the adoption of the new revenue recognition, pension or lease accounting standards; the impact on us or our clients of changes in legislation, regulation and legal guidance or interpretations in the jurisdictions in which we operate, including with respect to U.S. tax reform; seasonality due to the impact of regulatory deadlines, policy renewals and other timing factors to which our clients are subject; the success of our acquisitions or investments; 21 • macroeconomic factors such as changes in foreign exchange rates, interest rates and • global securities markets, particularly in the case of Mercer, where fees in its investments business and certain other business lines are derived from the value of assets under management or administration; and general economic conditions, including factors beyond our control affecting economic conditions such as severe weather or other catastrophic events, since results of operations are directly affected by the levels of business activity of our clients, which in turn are affected by the level of economic activity in the industries and markets that they serve. A significant portion of our total operating expenses is relatively fixed in the short term. Therefore, a variation in the number of client assignments or in the timing of the initiation or the completion of client assignments can cause significant variations in quarterly operating results for these businesses. Credit rating downgrades would increase our financing costs and could subject us to operational risk. Currently, the Company's senior debt is rated A- by S&P and Baa1 by Moody's. The ratings from both S&P and Moody's currently carry a Stable outlook. If we need to raise capital in the future (for example, in order to fund maturing debt obligations or finance acquisitions or other initiatives), credit rating downgrades would increase our financing costs, and could limit our access to financing sources. Further, a downgrade to a rating below investment-grade could result in greater operational risks through increased operating costs and increased competitive pressures. Global Operations We are exposed to multiple risks associated with the global nature of our operations. We conduct business globally. In 2017, approximately 50% of the Company's total revenue was generated from operations outside the United States, and over one-half of our employees were located outside the United States. We expect to expand our non-U.S. operations further. The geographic breadth of our activities subjects us to significant legal, economic, operational, market, compliance and reputational risks. These include, among others, risks relating to: • • • • economic and political conditions in the countries in which we operate; client concentration in certain high-growth countries in which we operate; the length of payment cycles and potential difficulties in collecting accounts receivable; unexpected increases in taxes or changes in U.S. or foreign tax laws, rulings, policies or related legal and regulatory interpretations, including recent international initiatives to require multinational enterprises, like ours, to report profitability on a country-by-country basis, which could increase scrutiny by, or cause disagreements with, foreign tax authorities; potential transfer pricing-related tax exposures that may result from the flow of funds among our subsidiaries and affiliates in the various jurisdictions in which we operate; • withholding or other taxes that foreign governments may impose on the payment of • • • • • • • dividends or other remittances to us from our non-U.S. subsidiaries; potential conflicts of interest that may arise as we expand the scope of our businesses and our client base; international hostilities, terrorist activities, natural disasters and infrastructure disruptions; local investment or other financial restrictions that foreign governments may impose; potential lawsuits, investigations, market studies, reviews or other activity by foreign regulatory or law enforcement authorities, which may result in related private litigation or increased scrutiny from U.S. or other regulators; potential costs and difficulties in complying with a wide variety of foreign laws and regulations (including tax systems) administered by foreign government agencies, some of which may conflict with U.S. or other sources of law; potential costs and difficulties in complying, or monitoring compliance, with foreign and U.S. laws and regulations that are applicable to our operations abroad, including trade 22 sanctions laws relating to countries such as Cuba, Iran, Russia, Sudan and Syria and anti-corruption laws such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 2010; limitations or restrictions that foreign or U.S. governments and regulators may impose on the products or services we sell, the methods by which we sell our products and services and the manner in which and the amounts we are compensated; limitations that foreign governments may impose on the conversion of currency or the payment of dividends or other remittances to us from our non-U.S. subsidiaries; engaging and relying on third parties to perform services on behalf of the Company; and potential difficulties in monitoring employees in geographically dispersed locations. • • • • Acquisitions and Dispositions Risks We face risks when we acquire and dispose of businesses. We have a history of making acquisitions and investments, including a total of 111 in the period 2012-2017. We expect that acquisitions will continue to be a key part of our business strategy. Our success in this regard will depend on our ability to identify and compete for appropriate acquisition candidates and to complete the transactions we decide to pursue with favorable results. As we typically acquire other professional services firms, the success of our transactions is also highly dependent on the retention of the key employees of our acquisition targets. While we intend that our acquisitions will improve our competitiveness and profitability, we cannot be certain that our past or future acquisitions will be accretive to earnings or otherwise meet our operational or strategic expectations. Acquisitions involve special risks, including accounting, regulatory, compliance, tax, information technology or human resources issues that could arise in connection with, or as a result of, the acquisition of the acquired company; the assumption of unanticipated liabilities and contingencies; difficulties in integrating acquired businesses; possible management distraction; and the inability of acquired businesses to achieve the levels of revenue, profit, productivity or synergies we anticipate or otherwise perform as we expect on the timeline contemplated. In addition, if in the future, the performance of our reporting units or an acquired business varies from our projections or assumptions, or estimates about future profitability of our reporting units or an acquired business change, the estimated fair value of our reporting units or an acquired business could change materially and could result in an impairment of goodwill and other acquisition-related intangible assets recorded on our balance sheet or in adjustments in contingent payment amounts. As of December 31, 2017, the Company's consolidated balance sheet reflected $10.4 billion of goodwill and intangible assets, representing approximately 51% of the Company's total consolidated assets and allocated by reporting segment as follows: Risk and Insurance Services, $7.6 billion and Consulting, $2.8 billion. Given the significant size of the Company's goodwill and intangible assets, an impairment could have a material adverse effect on our results of operations in any given period. When we dispose of businesses, we may continue to be subject to certain liabilities of that business after its disposition relating to the period of our ownership and may not be able to negotiate for limitations on those liabilities. We are also subject to the risk that the sales price is less than the amount reflected on our balance sheet. 23 RISKS RELATING TO OUR RISK AND INSURANCE SERVICES SEGMENT Our Risk and Insurance Services segment, conducted through Marsh and Guy Carpenter, represented 54% of the Company's total revenue in 2017. Our business in this segment is subject to particular risks. Results in our Risk and Insurance Services segment may be adversely affected by a general decline in economic activity. Demand for many types of insurance and reinsurance generally rises or falls as economic growth expands or slows. This dynamic affects the level of commissions and fees generated by Marsh and Guy Carpenter. To the extent our clients become adversely affected by declining business conditions, they may choose to limit their purchases of insurance and reinsurance coverage, as applicable, which would inhibit our ability to generate commission revenue and other revenue based on premiums placed by us. Also, the insurance they seek to obtain through us may be impacted by changes in their assets, property values, sales or number of employees, which may reduce our commission revenue, and they may decide not to purchase our risk advisory or other services, which would inhibit our ability to generate fee revenue. Moreover, insolvencies and combinations associated with an economic downturn, especially insolvencies and combinations in the insurance industry, could adversely affect our brokerage business through the loss of clients or by limiting our ability to place insurance and reinsurance business, as well as our revenues from insurers. Guy Carpenter is especially susceptible to this risk given the limited number of insurance company clients and reinsurers in the market place. Volatility or declines in premiums and other market trends may significantly impede our ability to grow revenues and profitability. A significant portion of our Risk and Insurance Services revenue consists of commissions paid to us out of the premiums that insurers and reinsurers charge our clients for coverage. We do not determine the insurance premiums on which our commissions are generally based. Our revenues and profitability are subject to change to the extent that premium rates fluctuate or trend in a particular direction. The potential for changes in premium rates is significant, due to the normal cycles of pricing in the commercial insurance and reinsurance markets. As traditional insurance companies continue to rely on non-affiliated brokers or agents to generate premium, those insurance companies may seek to reduce their expenses by lowering their commission rates. The reduction of these commission rates, along with general volatility or declines in premiums, may significantly affect our profitability. Because we do not determine the timing or extent of premium pricing changes, it is difficult to accurately forecast our commission revenues, including whether they will significantly decline. As a result, we may have to adjust our plans for future acquisitions, capital expenditures, dividend payments, loan repayments and other expenditures to account for unexpected changes in revenues, and any decreases in premium rates may adversely affect the results of our operations. In addition to movements in premium rates, our ability to generate premium-based commission revenue may be challenged by disintermediation and the growing availability of alternative methods for clients to meet their risk-protection needs. This trend includes a greater willingness on the part of corporations to self-insure, the use of captive insurers, and the presence of capital markets-based solutions for traditional insurance and reinsurance needs. Further, the profitability of our Risk and Insurances Services segment depends in part on our ability to be compensated for the analytical services and other advice that we provide, including the consulting and analytics services that we provide to insurers. If we are unable to achieve and maintain adequate billing rates for all of our services, our margins and profitability could decline. Adverse legal developments and future regulations concerning how intermediaries are compensated by insurers or clients, as well as allegations of anti-competitive behavior or conflicts of interest more broadly, could have a material adverse effect on Marsh’s business, results of operations and financial condition. The ways in which insurance intermediaries are compensated receive scrutiny from regulators in part because of the potential for anti-competitive behavior and conflicts of interest. The vast majority of the compensation that Marsh receives is in the form of retail fees and commissions that are paid by the client or paid from premium that is paid by the client. The amount of other compensation that we receive from 24 insurance companies, separate from retail fees and commissions, has increased in the last several years, both on an underlying basis and through acquisition. This other compensation includes payment for (i) consulting and analytics services provided to insurers; (ii) administrative and other services provided to insurers (including services relating to the administration and management of quota shares, lineslips, panels and other facilities); and (iii) contingent commissions (paid by insurers based on factors such as volume or profitability of Marsh's placements). These other revenue streams present potential regulatory, litigation and reputational risks that may arise from alleged anti-competitive behavior or conflicts of interest, and future changes in the regulatory environment may impact our ability to collect such revenue. For example, in November 2017, the FCA announced the terms of reference for a market study concerning the London wholesale insurance broker sector, which affects Marsh and Guy Carpenter. The FCA is conducting the study to assess "how effective competition is working in the wholesale insurance broker sector" and "how brokers influence competition in the underwriting sector." Many of the questions raised by the FCA in the terms of reference relate to broker compensation and fee-generating business practices. The FCA is expected to publish its interim report in the fall of 2018, with a final report expected in 2019. The timing and impacts of the study remain uncertain, and the study may lead to remedies on the industry that could adversely impact Marsh or Guy Carpenter’s business. These or other adverse regulatory, legal or other developments could have a material adverse effect on our business and expose the Company to negative publicity and reputational harm. RISKS RELATING TO OUR CONSULTING SEGMENT Our Consulting segment, conducted through Mercer and Oliver Wyman Group, represented 46% of our total revenue in 2017. Our businesses in this segment are subject to particular risks. Mercer’s Investment Management and Related Services (IMS) business is subject to a number of risks, including risks related to third-party investment managers, operational risk, conflicts of interest, asset performance and regulatory compliance, that, if realized, could result in significant damage to our business. Mercer’s IMS business provides clients with investment consulting and investment management (also referred to as "delegated solutions" or "fiduciary management") services. In the investment consulting business, clients make and implement their own investment decisions based upon advice provided by Mercer. In its delegated solutions business, Mercer implements the client’s investment policy by engaging and overseeing third-party asset managers who determine which investments to buy and sell. To effect implementation of a client’s investment policy, Mercer may utilize its "manager of managers" investment funds. Mercer’s IMS business is subject to a number of risks, including risks related to third-parties, our operations, conflicts of interest, asset performance and regulatory compliance and scrutiny, which could arise in connection with these offerings. For example, Mercer’s due diligence on an asset manager may fail to uncover material deficiencies or fraud that could result in investment losses to a client. There is a risk that Mercer will fail to properly implement a client’s investment policy, which could cause an incorrect or untimely allocation of client assets among asset managers or strategies. Mercer may also be perceived as recommending certain asset managers to clients, or offering delegated solutions to an investment consulting client, solely to enhance its own compensation. Asset classes may perform poorly, or asset managers may underperform their benchmarks, due to poor market performance, a downturn in the global equity markets, negligence or other reasons, resulting in poor returns or loss of client capital. These risks, if realized, could result in significant liability and damage our business. In addition, in June 2017, the FCA issued a final report in connection with a market study of the U.K. asset management industry, which includes asset managers and investment consultants, including Mercer. Following the report, in September 2017, the FCA announced its decision to refer the investment consulting and fiduciary management markets to the U.K. Competition & Markets Authority (the "CMA") for a market investigation. The CMA expects to conclude its investigation of the investment consulting and fiduciary management markets by March 2019, and the CMA may impose remedies on the industry that may adversely affect Mercer’s U.K. investment consulting and delegated solutions businesses. 25 Revenues for the services provided by our Consulting segment may decline for various reasons, including as a result of changes in economic conditions, the value of equity, debt and other asset markets, our clients’ or an industry's financial condition or government regulation. Until recently, global economic conditions have negatively affected businesses and financial institutions. Many of our clients, including financial institutions, corporations, government entities and pension plans, have reduced expenses, including amounts spent on consulting services, and used internal resources instead of consultants. The evolving needs and financial circumstances of our clients may reduce demand for our consulting services and our revenues and profitability. If the economy or markets in which we operate experience weakness or deteriorate, our business, financial condition and results of operations could be materially and adversely affected. In addition, some of Mercer's IMS business generates fees based upon the value of the clients’ assets under management or advisement. Changes in the value of equity, debt, currency, real estate, commodities or other asset classes could cause the value of assets under management or advisement, and the fees received by Mercer, to decline. Such changes could also cause clients to withdraw funds from Mercer’s IMS business in favor of other investment service providers. In either case, our business, financial condition and results of operations could be materially and adversely affected. Further, revenue received by Mercer as investment manager to the majority of the Mercer-managed investment funds is reported in accordance with U.S. GAAP on a gross basis rather than a net basis, with sub-advisor fees reflected as an expense. Therefore the reported revenue for these offerings does not fully reflect the amount net revenue ultimately attributable to Mercer. Demand for many of Mercer's benefits services is affected by government regulation and tax laws, rulings, policies and interpretations, which drive our clients' needs for benefits-related services. Significant changes in government regulations affecting the value, use or delivery of benefits and human resources programs, including changes in regulations relating to health and welfare plans, defined contribution plans or defined benefit plans, may adversely affect the demand for or profitability of Mercer's services. Factors affecting defined benefit pension plans and the services we provide relating to those plans could adversely affect Mercer. Mercer currently provides corporate, multi-employer and public clients with actuarial, consulting and administration services relating to defined benefit pension plans. The nature of our work is complex. Our actuarial services involve numerous assumptions and estimates regarding future events, including interest rates used to discount future liabilities, estimated rates of return for a plan's assets, healthcare cost trends, salary projections and participants' life expectancies. Our consulting services involve the drafting and interpretation of trust deeds and other complex documentation governing pension plans. Our administration services include calculating benefits within complicated pension plan structures. Clients dissatisfied with our services have brought, and may bring, significant claims against us, particularly in the United States and the United Kingdom. In addition, a number of Mercer's clients have frozen or curtailed their defined benefit plans and have moved to defined contribution plans resulting in reduced revenue for Mercer's retirement business. These developments could adversely affect Mercer's business and operating results. The profitability of our Consulting segment may decline if we are unable to achieve or maintain adequate utilization and pricing rates for our consultants. The profitability of our Consulting businesses depends in part on ensuring that our consultants maintain adequate utilization rates (i.e., the percentage of our consultants' working hours devoted to billable activities). Our utilization rates are affected by a number of factors, including: • • • • • our ability to transition consultants promptly from completed projects to new assignments, and to engage newly-hired consultants quickly in revenue-generating activities; our ability to continually secure new business engagements, particularly because a portion of our work is project-based rather than recurring in nature; our ability to forecast demand for our services and thereby maintain appropriate headcount in each of our geographies and workforces; our ability to manage attrition; unanticipated changes in the scope of client engagements; 26 • • • • the potential for conflicts of interest that might require us to decline client engagements that we otherwise would have accepted; our need to devote time and resources to sales, training, professional development and other non-billable activities; the potential disruptive impact of acquisitions and dispositions; and general economic conditions. If the utilization rate for our consulting professionals declines, our profit margin and profitability could decline. In addition, the profitability of our Consulting businesses depends in part on the prices we are able to charge for our services. The prices we charge are affected by a number of factors, including: clients' perception of our ability to add value through our services; • • market demand for the services we provide; • • • our ability to develop new services and the introduction of new services by competitors; the pricing policies of our competitors; the extent to which our clients develop in-house or other capabilities to perform the services that they might otherwise purchase from us; and general economic conditions. • If we are unable to achieve and maintain adequate billing rates for our services, our profit margin and profitability could decline. Item 1B. Unresolved Staff Comments. There are no unresolved comments to be reported pursuant to Item 1B. Item 2. Properties. Marsh & McLennan Companies maintains its corporate headquarters in New York City. We also maintain other offices around the world, primarily in leased space. In certain circumstances we may have space that we sublet to third parties, depending upon our needs in particular locations. Marsh & McLennan Companies and certain of its subsidiaries own, directly and indirectly through special purpose subsidiaries, a 58% condominium interest covering approximately 900,000 square feet of office space in a 44 story condominium in New York City. This real estate serves as the Company's headquarters and is occupied primarily by the Company and its subsidiaries for general corporate use. The condominium interests are financed by a 30-year mortgage loan that is non-recourse to the Company unless the Company (i) is downgraded below B (stable outlook) by S&P or Fitch or B2 (stable outlook) by Moody's and such downgrade is continuing or (ii) an event of default under the mortgage loan has occurred. The mortgage is secured by a first priority assignment of leases and rents, including the leases which the Company and certain of its subsidiaries entered into with their affiliated special purpose subsidiaries which own the mortgaged condominium interests. The net rent due under those leases in effect services the mortgage debt. Item 3. Legal Proceedings. In April 2017, the Financial Conduct Authority in the United Kingdom (the "FCA") commenced a civil competition investigation into the aviation insurance and reinsurance sector. In connection with that investigation, the FCA carried out an on-site inspection at the London office of Marsh Limited, our Marsh and Guy Carpenter operating subsidiary in the United Kingdom. The FCA indicated that it had reasonable grounds for suspecting that Marsh Limited and other participants in the market have been sharing competitively sensitive information within the aviation insurance and reinsurance broking sector. In October 2017, the Company received a notice that the Directorate-General for Competition of the European Commission had commenced a civil investigation of a number of insurance brokers, including Marsh, regarding "the exchange of commercially sensitive information between competitors in relation to aviation and aerospace insurance and reinsurance broking products and services in the European Economic Area ("EEA"), as well as possible coordination between competitors." In light of the action 27 taken by the European Commission, the FCA informed Marsh Limited at the same time that it has discontinued its investigation under U.K. competition law into the aviation insurance and reinsurance sector. In July 2017, the Directorate-General for Competition of the European Commission together with the Irish Competition and Consumer Protection Commission conducted on-site inspections at the offices of Marsh and other industry participants in Dublin in connection with an investigation regarding the "possible participation in anticompetitive agreements and/or concerted practices contrary to [E.U. competition law] in the market for commercial motor insurance in the Republic of Ireland." In December 2017, we received a request from the Directorate-General for Competition of the European Commission seeking documents and information relating to its investigation. We are cooperating with these investigations and are conducting our own reviews. As these investigations are at early stages, we are unable to predict their likely timing, outcome or ultimate impact. There can be no assurance that the ultimate resolution of these or any related matters will not have a material adverse effect on our consolidated results of operations, financial condition or cash flows. We and our subsidiaries are also party to a variety of other legal, administrative, regulatory and government proceedings, claims and inquiries arising in the normal course of business. Additional information regarding certain legal proceedings and related matters is set forth in Note 14 to the consolidated financial statements appearing under Part II, Item 8 ("Financial Statements and Supplementary Data") of this report.

Management’s Discussion and Analysis of Financial Condition and Results of Operations General Marsh & McLennan Companies, Inc. and its consolidated subsidiaries (the "Company") is a global professional services firm offering clients advice and solutions in risk, strategy and people. Its businesses include: Marsh, the insurance broker, intermediary and risk advisor; Guy Carpenter, the risk and reinsurance specialist; Mercer, the provider of HR and Investment related financial advice and services; and Oliver Wyman Group, the management, economic and brand consultancy. With nearly 65,000 colleagues worldwide and annual revenue of more than $14 billion, the Company provides analysis, advice and transactional capabilities to clients in more than 130 countries. The Company conducts business through two segments: • Risk and Insurance Services includes risk management activities (risk advice, risk transfer and risk control and mitigation solutions) as well as insurance and reinsurance broking and services. The Company conducts business in this segment through Marsh and Guy Carpenter. • Consulting includes health, retirement, talent and investments consulting services and products, and specialized management, economic and brand consulting services. The Company conducts business in this segment through Mercer and Oliver Wyman Group. We describe the primary sources of revenue and categories of expense for each segment below, in our discussion of segment financial results. A reconciliation of segment operating income to total operating income is included in Note 15 to the consolidated financial statements included in Part II, Item 8 in this report. The accounting policies used for each segment are the same as those used for the consolidated financial statements. This Management's Discussion & Analysis ("MD&A") contains forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. See "Information Concerning Forward- Looking Statements" at the outset of this report.

The TCJA provides for a reduction in the U.S. corporate tax rate to 21% and the creation of a territorial tax system. The TCJA also changes the deductibility of certain expenses, primarily executive officers compensation. An aggregate charge of $460 million was recorded in the fourth quarter of 2017 as a result of the enactment of the TCJA. The TCJA provides for a transition to the territorial system through a deemed repatriation tax (the "transition tax") on undistributed earnings of non-U.S. subsidiaries. The Company recorded a provisional charge of $240 million in the fourth quarter of 2017 as an estimate of U.S. transition taxes and ancillary effects, including state taxes and foreign withholding taxes related to the change in permanent reinvestment status with respect to our pre-2018 foreign earnings. This transition tax is payable over eight years. The reduction of the U.S. corporate tax rate from 35% to 21%, reduces the value of the U.S. deferred tax assets and liabilities, accordingly, a net charge of $220 million was recorded. A more complete discussion of the TCJA and its impact on the Company’s results is included under the heading "Income Taxes". • Pension Settlement charge in the U.K. - The Defined Benefit Pension Plans in the U.K. allow participants an option for the payment of a lump sum distribution from plan assets before retirement in full satisfaction of the retirement benefits due to the participant as well as any survivor’s benefit. The Company’s policy under applicable U.S. GAAP is to treat these lump sum payments as a partial settlement of the plan liability if they exceed the sum of service cost plus interest cost components of net period pension cost of a plan for the year ("settlement thresholds"). The amount of lump sum payments through December 31, 2017 exceeded the settlement thresholds in two of the U.K. plans. This resulted in a non-cash settlement charge of $54 million recorded in December 2017, of which approximately 85% impacted Risk and Insurance Services. Consolidated operating income increased 7%, to $2.9 billion, in 2017 compared with $2.7 billion in 2016, reflecting the combined impact of a 6% increase in revenue and a 6% increase in expenses as compared with the prior year. Income before income taxes increased 7%, to $2.6 billion, reflecting the increase in operating income partly offset by higher interest expense, primarily reflecting an increase in average debt outstanding during the year resulting from the issuance of $1 billion of senior notes in January 2017, partly offset by the repayment of $250 million of senior notes in April 2017. Diluted earnings per share was $2.87 in 2017, compared with $3.38 in 2016. The decrease reflects a significantly higher effective tax rate in 2017, primarily resulting from an aggregate provisional charge of $460 million related to the enactment in December 2017 of U.S. tax reform and a pension settlement charge, which are discussed above. The impact from U.S. tax reform was partly offset by discrete tax items during the year, in particular the benefit from the required change in accounting for tax consequences related to stock compensation. The $460 million provisional charge related to U.S. tax reform reduced diluted earnings per share by $0.89. Average diluted shares outstanding for 2017 decreased to 519 million, compared with 524 million during 2016. Shares issued related to the vesting of share awards and the exercise of employee stock options, were more than offset by share repurchases during the year. Average shares outstanding in 2017 was also impacted by the change in accounting for stock compensation. Under the applicable guidance, the excess tax benefits for unvested shares and unexercised stock options are no longer included in the calculation of common stock equivalents ("CSEs") under the treasury stock method. This had the effect of increasing CSEs by approximately 1.7 million shares in 2017. Risk and Insurance Services operating income increased $118 million, or 7%, in 2017 compared with 2016. Revenue increased 7%, reflecting a 3% increase on an underlying basis and a 4% increase from acquisitions. Expense increased 7% or 2% on an underlying basis in 2017 compared with 2016. Consulting operating income increased $71 million, or 6%, to $1.2 billion in 2017 compared with 2016, reflecting the combined impact of 5% growth for both revenue and expense. 32 Consolidated operating income increased 10% to $2.7 billion in 2016 compared with $2.4 billion in 2015, reflecting the combined impact of a 2% increase in revenue and a 1% increase in expenses as compared to the prior year. Risk and Insurance Services operating income increased $214 million, or 14% in 2016 compared with 2015. Revenue increased 4% reflecting a 3% increase on an underlying basis and a 3% increase from acquisitions, partly offset by a decrease resulting from the impact of foreign currency translation of 2%. Expense increased 1% in 2016 compared with 2015. Consulting operating income increased $28 million, or 3%, to $1.1 billion in 2016 compared with 2015, reflecting the combined impact of 1% revenue growth, while expense was flat. 33 Consolidated Revenue and Expense Revenue - Components of Change The Company conducts business in many countries. As a result, foreign exchange rate movements may impact period-to-period comparisons of revenue. Similarly, certain other items such as the revenue impact of acquisitions and dispositions, including transfers among businesses, may impact period-to-period comparisons of revenue. Underlying revenue measures the change in revenue from one period to another by isolating these impacts. The impact of foreign currency exchange fluctuations, acquisitions and dispositions, including transfers among businesses, on the Company’s operating revenues by segment was as follows: Year Ended December 31, (In millions, except percentage figures) 2017 2016 Risk and Insurance Services Marsh Guy Carpenter Subtotal Fiduciary Interest Income Total Risk and Insurance Services Consulting Mercer Oliver Wyman Group Total Consulting Corporate/Eliminations Total Revenue $ 6,404 $ 5,976 1,187 7,591 39 7,630 4,528 1,916 6,444 1,141 7,117 26 7,143 4,323 1,789 6,112 (50) (44) $ 14,024 $ 13,211 * Components of revenue change may not add due to rounding.

Revenue Consolidated revenue was $14 billion in 2017, an increase of 6%, or 3% on an underlying basis. Revenue in the Risk and Insurance Services segment increased 7% in 2017 compared with 2016, or 3% on an underlying basis. Revenue increased 3% and 4% on an underlying basis at Marsh and Guy Carpenter, respectively, as compared with 2016. The Consulting segment's revenue increased 5% compared with 2016, or 4% on an underlying basis. Revenue increased 2% and 7% on an underlying basis at Mercer and Oliver Wyman Group, respectively, as compared with 2016. 35 Consolidated revenue was $13.2 billion in 2016, an increase of 2%, or 3% on an underlying basis. Revenue in the Risk and Insurance Services segment increased 4% in 2016 compared with 2015, or 3% on an underlying basis. Revenue increased 3% and 2% on an underlying basis at Marsh and Guy Carpenter, respectively, as compared with 2015. The Consulting segment's revenue increased 1% on a reported basis compared with 2015, or 3% on an underlying basis. Both Mercer and Oliver Wyman Group's revenue increased 3% on an underlying basis compared with 2015. Operating Expense Consolidated operating expenses increased 6% in 2017 compared with 2016, or 2% on an underlying basis. The increase in underlying expenses was primarily due to higher base salaries and incentive compensation costs, and the pension settlement charge discussed previously, partly offset by lower costs related to liabilities for errors and omissions. Consolidated operating expenses increased 1% in 2016 compared with the same period in 2015 on both a reported and underlying basis. The underlying expense increase reflects higher base salary costs, higher amortization of identified intangible assets and the impact of the net benefit from the termination of the Company's post-65 retiree medical reimbursement plan in the United States (the "RRA Plan"), which was recorded in the first quarter of 2015, partly offset by decreases in defined benefit plan pension expense and contingent acquisition consideration expense. Risk and Insurance Services In the Risk and Insurance Services segment, the Company’s subsidiaries and other affiliated entities act as brokers, agents or consultants for insureds, insurance underwriters and other brokers in the areas of risk management, insurance broking and insurance program management services, primarily under the name of Marsh; and engage in reinsurance broking, catastrophe and financial modeling services and related advisory functions, primarily under the name of Guy Carpenter. Marsh and Guy Carpenter are compensated for brokerage and consulting services primarily through fees paid by clients or commissions paid out of premiums charged by insurance and reinsurance companies. Commission rates vary in amount depending upon the type of insurance or reinsurance coverage provided, the particular insurer or reinsurer, the capacity in which the broker acts and negotiates with clients. Revenues can be affected by premium rate levels in the insurance/reinsurance markets, the amount of risk retained by insurance and reinsurance clients themselves and by the value of the risks that have been insured since commission-based compensation is frequently related to the premiums paid by insureds/reinsureds. In many cases, fee compensation may be negotiated in advance, based on the type of risk, coverage required and service provided by the Company and ultimately, the extent of the risk placed into the insurance market or retained by the client. The trends and comparisons of revenue from one period to the next can be affected by changes in premium rate levels, fluctuations in client risk retention and increases or decreases in the value of risks that have been insured, as well as new and lost business, and the volume of business from new and existing clients. Marsh also receives other compensation from insurance companies, separate from retail fees and commissions. This compensation includes, among other things, payment for consulting and analytics services provided to insurers; administrative and other services provided to or on behalf of insurers (including services relating to the administration and management of quota share, panels and other facilities in which insurers participate); and contingent commissions. Marsh and Guy Carpenter also receive interest income on certain funds (such as premiums and claims proceeds) held in a fiduciary capacity for others. The investment of fiduciary funds is regulated by state and other insurance authorities. These regulations typically require segregation of fiduciary funds and limit the types of investments that may be made with them. Interest income from these investments varies depending on the amount of funds invested and applicable interest rates, both of which vary from time to time. For presentation purposes, fiduciary interest is segregated from the other revenues of Marsh and Guy Carpenter and separately presented within the segment, as shown in the revenue by segments charts presented earlier in this MD&A. 36 The results of operations for the Risk and Insurance Services segment are presented below: (In millions of dollars, except percentages) Revenue Compensation and Benefits Other Operating Expenses Operating Expenses Operating Income Operating Income Margin Revenue 2017 7,630 4,031 1,728 5,759 1,871 $ $ 2016 7,143 3,732 1,658 5,390 1,753 2015 6,869 3,629 1,701 5,330 1,539 $ $ $ $ 24.5% 24.5% 22.4% Revenue in the Risk and Insurance Services segment increased 7% in 2017 compared with 2016, due to a 3% growth in underlying revenue and 4% growth from acquisitions. In Marsh, revenue increased 7% to $6.4 billion in 2017 as compared with 2016, reflecting a 3% increase on an underlying basis and a 5% increase from acquisitions. U.S./Canada had underlying revenue growth of 4%. International operations increased 2% on an underlying basis, reflecting increases of 6% in Asia Pacific and 7% in Latin America, while growth in EMEA was flat. Guy Carpenter’s revenue increased 4% to $1.2 billion in 2017 compared with 2016, for both a reported and underlying basis. Fiduciary interest income was $39 million in 2017 compared with $26 million in 2016 due to the combined effect of higher average invested funds and higher interest rates. The Risk and Insurance Services segment completed seven acquisitions during 2017. Information regarding those acquisitions is included in Note 4 to the consolidated financial statements. Revenue in the Risk and Insurance Services segment increased 4% in 2016 compared with 2015, as a 3% growth in underlying revenue and 3% growth from acquisitions was partly offset by a 2% decrease resulting from the impact of foreign currency translation. In Marsh, revenue of $6 billion increased 4% in 2016 as compared with 2015, reflecting a 3% increase on an underlying basis and a 4% increase from acquisitions, offset by a 2% decrease resulting from the impact of foreign currency translation. The underlying revenue increase reflects growth in all major geographies. International operations had underlying revenue growth of 3% reflecting increases of 2% in EMEA, 3% in Asia Pacific and 8% in Latin America, while U.S./Canada increased 2%. Guy Carpenter’s revenue increased 2% to $1.1 billion in 2016 compared with 2015, for both a reported and underlying basis. Fiduciary interest income was $26 million in 2016 compared with $21 million in 2015 due to the combined effect of higher average invested funds and higher interest rates. The Risk and Insurance Services segment completed nine acquisitions during 2016. Expense Expense in the Risk and Insurance Services segment increased 7% in 2017 compared with 2016, reflecting a 2% increase on an underlying basis and a 5% increase from acquisitions. The underlying expense increase is primarily due to higher base salaries, incentive compensation costs and the U.K. pension settlement charge discussed previously, partly offset by lower costs related to liabilities for errors and omissions. Expense in the Risk and Insurance Services segment increased 1% on both a reported and underlying basis in 2016 compared with 2015. The impact of foreign currency translation reduced expenses by 3%, which was offset by a 3% increase related to acquisitions. The increase in underlying expense reflects higher base salary and incentive compensation costs, higher identified intangible asset amortization expense and the impact of the net benefit from the termination of the RRA Plan which was recorded in the first quarter of 2015, offset by a decrease in defined benefit plan pension expense and lower contingent consideration costs related to acquisitions. 37 Consulting Effective January 1, 2017, Mercer merged its investment and retirement businesses into a newly-created wealth business. We believe this combination better aligns Mercer’s investment management capabilities globally. The Company conducts business in its Consulting segment through two main business groups, Mercer and Oliver Wyman Group. Mercer provides consulting expertise, advice, services and solutions in the areas of health, retirement, talent and investments. Oliver Wyman Group provides specialized management, economic and brand consulting services. The major component of revenue in the Consulting business is fees paid by clients for advice and services. Mercer, principally through its health line of business, also earns revenue in the form of commissions received from insurance companies for the placement of group (and occasionally individual) insurance contracts, primarily life, health and accident coverages. Revenue for Mercer’s investment management business and certain of Mercer’s defined contribution administration services consists principally of fees based on assets under management or administration. Revenue in the Consulting segment is affected by, among other things, global economic conditions, including changes in clients’ particular industries and markets. Revenue is also affected by competition due to the introduction of new products and services, broad trends in employee demographics, including levels of employment, the effect of government policies and regulations, and fluctuations in interest and foreign exchange rates. Revenues from the provision of investment management services and retirement trust and administrative services are significantly affected by the level of assets under management or administration and securities market performance. For the investment management business, revenues from the majority of funds are included on a gross basis in accordance with U.S. GAAP and include reimbursable expenses incurred by professional staff and sub-advisory fees, and the related expenses are included in other operating expenses. The results of operations for the Consulting segment are presented below: (In millions of dollars, except percentages) Revenue Compensation and Benefits Other Operating Expenses Operating Expenses Operating Income Operating Income Margin Revenue 2017 6,444 3,509 1,761 5,270 1,174 $ $ 2016 6,112 3,385 1,624 5,009 1,103 $ $ 2015 6,064 3,354 1,635 4,989 1,075 $ $ 18.2% 18.1% 17.7% Consulting revenue in 2017 increased 5% compared with 2016, reflecting a 4% increase on an underlying basis and 2% growth from acquisitions. Mercer's revenue increased 5% to $4.5 billion over the prior year, or 2% on an underlying basis. Mercer's year over year revenue comparison also reflects an increase of 2% from acquisitions. The underlying revenue growth reflects an increase in Career of 5%, Health of 2% and Wealth of 2%. Within Wealth, Investment Management & Related Services increased 10% while Defined Benefit Consulting & Administration decreased 2% compared with the prior year. Oliver Wyman Group’s revenue increased 7% in 2017 compared with 2016, for both a reported and underlying basis. The Consulting segment completed three acquisitions during 2017. Information regarding these acquisitions is included in Note 4 to the consolidated financial statements. Consulting revenue in 2016 increased 1% compared with 2015, reflecting a 3% increase on an underlying basis offset by a 2% decrease from the impact of foreign currency translation. Mercer’s revenue of $4.3 billion was flat when compared with 2015 but increased 3% on an underlying basis. Mercer's year over year revenue comparison reflects a decrease of 2% from the impact of foreign currency translation. The underlying revenue growth reflects an increase in Wealth of 2%, Health of 3% and Career of 5%. Within Wealth, Investment Management & Related Services increased 6% while Defined Benefit Consulting & Administration was flat compared with 2015. Oliver Wyman Group’s revenue increased 2% in 2016 38 compared with 2015, reflecting an increase of 3% on an underlying basis, partly offset by a decrease of 2% from the impact of foreign currency translation. The Consulting segment completed six acquisitions during 2016. Expense Consulting expense in 2017 increased 5% compared with 2016, reflecting an increase of 3% on an underlying basis and a 3% increase from the impact of acquisitions. The increase in underlying expense reflects higher base salaries, asset based fees and outside service costs, partly offset by lower severance costs and lower costs related to liabilities for errors and omissions. Consulting expense in 2016 was essentially flat compared with 2015, reflecting an increase of 2% on an underlying basis offset by a 2% decrease from the impact of foreign currency translation. The increase in underlying expense reflects higher base salaries and the impact of the net benefit from the termination of the RRA plan which was recorded in the first quarter of 2015, partly offset by lower defined benefit plan pension expense. Corporate and Other Corporate expense in 2017 was $189 million compared with $192 million in 2016. The decrease in expense is primarily due to lower consulting, occupancy and general insurance costs. Corporate expense in 2016 was $192 million compared with $195 million in 2015, reflecting lower executive compensation and lower defined benefit pension costs. Other Corporate Items Interest Interest income earned on corporate funds amounted to $9 million in 2017 compared with $5 million in 2016. Interest expense in 2017 was $237 million compared with $189 million in 2016. The increase in interest expense was primarily due to higher average debt outstanding in 2017. Interest income earned on corporate funds amounted to $5 million in 2016 compared with $13 million in 2015. The decrease is due to the combined effects of a lower level of invested funds and lower interest rates. Interest expense in 2016 was $189 million compared with $163 million in 2015 due to higher average outstanding debt in 2016. Investment Income The caption "Investment income (loss)" in the consolidated statements of income comprises realized and unrealized gains and losses from investments recognized in current earnings. It includes, when applicable, other-than-temporary declines in the value of debt and available-for-sale securities and equity method gains or losses on its investment in private equity funds. The Company's investments may include direct investments in insurance, consulting and related companies and investments in private equity funds. The Company recorded net investment income of $15 million in 2017 compared to less than $1 million in 2016 and $38 million in 2015. The increase in 2017 versus 2016 was primarily due to a gain on the sale of an investment and higher equity method gains related to the Company's investments in private equity funds. Net investment income in 2015 was primarily related to the general partner carried interest from Trident III. Stonepoint Capital, the investment manager of Trident III, substantially liquidated the remaining two investments of Trident III during the third quarter of 2015, which resulted in the Company recognizing its remaining deferred performance fees. Income Taxes On December 22, 2017, the U.S. enacted the TCJA. The TCJA provides for a reduction in the U.S. corporate tax rate to 21% and the creation of a territorial tax system. The TCJA also changes the deductibility of certain expenses, primarily executive officers compensation. The Company recorded a provisional charge of $460 million related to the enactment of the TCJA. As discussed in Note 6 to the consolidated financial statements this provisional charge may be adjusted in 2018. The TCJA provides for a transition to the territorial system via a transition tax on undistributed earnings of non-U.S. subsidiaries. The Company recorded a provisional charge of $240 million in the fourth quarter as an estimate of U.S. transition taxes and ancillary effects, including state taxes and foreign withholding taxes related to the 39 change in permanent reinvestment status with respect to our pre-2018 foreign earnings. This transition tax is payable over eight years. The reduction of the U.S. corporate tax rate from 35% to 21%, reduces the value of the US deferred tax assets and liabilities, accordingly, a charge of $220 million was recorded. The more complete discussion of the TCJA and its impact on the Company’s results is further below. The Company's consolidated effective tax rate was 42.9%, 27.6% and 29.1% in 2017, 2016 and 2015, respectively. The effective tax rate in 2017 reflects the provisional estimate of U.S. tax reform as well as the impact of the required change in accounting for the tax effects of equity awards. The 2017, 2016 and 2015 rates also reflect foreign operations which historically have been taxed at rates below the U.S. statutory tax rate, including the effect of repatriation, as well as the impact of discrete tax matters such as tax legislation, changes in valuation allowances, nontaxable adjustments to contingent acquisition consideration and the true-up of the tax provision to amounts filed in the Company's tax returns. In 2017, pre-tax income in the U.K., Barbados, Canada, Australia, and Ireland accounted for approximately 60% of the Company's total non-U.S. pre-tax income, with effective rates in those countries of 20%, 1%, 27%, 31% and 12%, respectively. As noted above, the TCJA significantly increased income tax expense from two discrete charges discussed above. The lower U.S. corporate rate is expected to provide a significant ongoing benefit to our effective tax rate and U.S. cash tax liabilities due to the significantly lower U.S. statutory tax rate and the quasi-territorial system. As a U.S. domiciled parent holding company, Marsh & McLennan Companies, Inc. is the issuer of essentially all of the Company's external indebtedness, and incurs the related interest expense in the U.S. Further, most senior executive and oversight functions are conducted in the U.S. and the associated costs are incurred primarily in the United States. The mandatory taxation of accumulated undistributed foreign earnings through the transition tax substantially changed the economic considerations of continued permanent investment of those accumulated earnings, a key component of our global capital strategy. As a result of the transition tax, the Company anticipates repatriating the majority of the accumulated earnings that was previously intended to be permanently re-invested outside of the U.S. We continue to evaluate our global investment strategy in light of expected relief from U.S. tax reform under the new territorial tax regime for future foreign earnings. The effective tax rate may vary significantly from period to period. The rate is sensitive to the geographic mix of the Company's earnings and repatriation of cash, which may result in higher or lower effective tax rates. Losses in certain jurisdictions cannot be offset by earnings from other operations, and may require valuation allowances that affect the rate, depending on estimates of the realizability of associated deferred tax assets. The effective tax rate is also sensitive to changes in unrecognized tax benefits, including the impact of settled tax audits and expired statutes of limitation. The realization of deferred tax assets depends on generating future taxable income during the periods in which the tax benefits are deductible or creditable. Tax liabilities are determined and assessed jurisdictionally by legal entity or filing group. Certain taxing jurisdictions allow or require combined or consolidated tax filings. The Company assessed the realizability of its deferred tax assets. The Company considered all available evidence, including the existence of a recent history of losses, placing particular weight on evidence that could be objectively verified. A valuation allowance was recorded to reduce deferred tax assets to the amount that the Company believes is more likely than not to be realized. Changes in tax laws, rulings, policies or related legal and regulatory interpretations occur frequently and may also have significant favorable or adverse impacts on our current assumptions and effective tax rate. Liquidity and Capital Resources The Company is organized as a legal entity separate and distinct from its operating subsidiaries. As the Company does not have significant operations of its own, the Company is dependent upon dividends and other payments from its operating subsidiaries to pay principal and interest on its outstanding debt obligations, pay dividends to stockholders, repurchase its shares and pay corporate expenses. The Company also provides financial support to its operating subsidiaries for acquisitions, investments and certain parts of their business that require liquidity, such as the capital markets business of Guy Carpenter. Other sources of liquidity include borrowing facilities discussed below in financing cash flows. 40 The Company derives a significant portion of its revenue and operating profit from operating subsidiaries located outside of the United States. Funds from those operating subsidiaries are regularly repatriated to the United States out of annual earnings. At December 31, 2017, the Company had approximately $1.0 billion of cash and cash equivalents in its foreign operations, which includes $171 million of operating funds required to be maintained for regulatory requirements or as collateral under certain captive insurance arrangements. The Company expects to continue its practice of repatriating foreign funds from its non-U.S. operating subsidiaries out of current annual earnings, and with respect to repatriating 2017 and prior earnings, it is in the process of fully evaluating such factors as its short- and long-term capital needs, acquisition and borrowing strategies, and the availability of cash for repatriation for each of its subsidiaries as it considers its permanent reinvestment assertions going forward in light of the enactment at the end of 2017 of the TCJA. During 2017, the Company recorded foreign currency translation adjustments which increased net equity by $715 million. A weakening of the U.S. dollar against foreign currencies would increase the translated U.S. dollar value of the Company’s net investments in its non- U.S. subsidiaries, as well as the translated U.S. dollar value of cash repatriations from those subsidiaries. Cash on our consolidated balance sheets includes funds available for general corporate purposes. Funds held on behalf of clients in a fiduciary capacity are segregated and shown separately in the consolidated balance sheets as an offset to fiduciary liabilities. Fiduciary funds cannot be used for general corporate purposes, and should not be considered as a source of liquidity for the Company. Operating Cash Flows The Company generated $1.9 billion of cash from operations in 2017, compared with $2.0 billion in 2016. These amounts reflect the net income of the Company during those periods, excluding gains or losses from investments, adjusted for non-cash charges and changes in working capital which relate primarily to the timing of payments of accrued liabilities or receipts of assets and pension contributions. Pension-Related Items Contributions During 2017, the Company contributed $85 million to its U.S. pension plans and $229 million to non-U.S. pension plans compared to contributions of $27 million to U.S. plans and $187 million to non-U.S. plans in 2016. In the United States, contributions to the tax-qualified defined benefit plans are based on ERISA guidelines and the Company generally expects to maintain a funded status of 80% or more of the liability determined under the ERISA guidelines. There was a $6 million contribution to the U.S. qualified plan to meet the ERISA funding requirement in 2017. In addition, the Company made a $50 million discretionary contribution to the U.S. qualified plan in December 2017 and $29 million of contributions to its non- qualified plans. The Company expects to contribute approximately $27 million to its U.S. pension plans in 2018. The Company contributed $129 million to the U.K. plans in 2017, including an expense allowance of approximately $9 million. Based on the funding test carried out at November 1, 2017, the Company contributions to the U.K. plans in 2018 are expected to be approximately $22 million, including the expense allowance. Outside the United States, the Company has a large number of non-U.S. defined benefit pension plans, the largest of which are in the U.K., which comprise approximately 81% of non-U.S. plan assets at December 31, 2017. Contribution rates for non-U.S. plans are generally based on local funding practices and statutory requirements, which may differ significantly from measurements under U.S. GAAP. In the U.K., the assumptions used to determine pension contributions are the result of legally-prescribed negotiations between the Company and the plans' trustee that typically occur every three years in conjunction with the actuarial valuation of the plans. Currently, this results in a lower funded status than under U.S. GAAP and may result in contributions irrespective of the U.S. GAAP funded status. In November 2016, the Company and the Trustee of the U.K. Defined Benefits Plans agreed to a funding deficit recovery plan for the U.K. defined benefit pension plans. The current agreement with the Trustee sets out the annual deficit contributions which would be due based on the deficit at December 31, 2015. The funding level is subject to re-assessment, in most cases on November 1 of each year. If the funding 41 level on November 1 is sufficient, no deficit funding contributions will be required in the following year, and the contribution amount will be deferred. The funding level was re-assessed on November 1, 2017 and no deficit funding contributions are required in 2018. The funding level will be re-assessed on November 1, 2018. As part of a long-term strategy, which depends on having greater influence over asset allocation and overall investment decisions, in November 2016 the Company renewed its agreement to support annual deficit contributions by the U.K. operating companies under certain circumstances, up to GBP 450 million over a seven-year period. In the aggregate, the Company expects to contribute approximately $82 million to its non-U.S. defined benefit plans in 2018, comprising approximately $60 million to plans outside of the U.K. and $22 million to the U.K. plans. Changes to Pension Plans In March 2017, the Company modified its defined benefit pension plans in Canada to discontinue further benefit accruals for participants after December 31, 2017 and replaced them with a defined contribution arrangement. The Company also amended its post-retirement benefits plan in Canada so that individuals who retire after April 1, 2019 will not be eligible to participate, except in certain situations. The Company re-measured the assets and liabilities of the plans, based on assumptions and market conditions on the amendment date. In October 2016, the Company modified its U.S. defined benefit pension plans to discontinue further benefit accruals for participants after December 31, 2016. At the same time, the Company amended its U.S. defined contribution retirement plans for most of its U.S. employees to add an automatic Company contribution equal to 4% of eligible base pay beginning on January 1, 2017. This new Company contribution, together with the Company’s current matching contribution, provides eligible U.S. employees with the opportunity to receive a total contribution of up to 7% of eligible base pay. As required under GAAP, the defined benefit plans that were significantly impacted by the modification were re-measured in October 2016 using market data and assumptions as of the modification date. The net periodic pension expense recognized in 2016 reflects the weighted average costs of the December 31, 2015 measurement and the October 2016 re-measurement. In addition, the U.S. qualified plans were merged effective December 30, 2016, since no participants would be receiving benefit accruals after December 2016. Effective August 1, 2015, the Company amended its Ireland defined benefit pension plans to close those plans to future benefit accruals and replaced those plans with a defined contribution arrangement. The Company re-measured the assets and liabilities of the plans, based on assumptions and market conditions on the amendment date. Changes in Funded Status and Expense The year-over-year change in the funded status of the Company's pension plans is impacted by the difference between actual and assumed results, particularly with regard to return on assets, and changes in the discount rate, as well as the amount of Company contributions, if any. Unrecognized actuarial losses were approximately $1.8 billion and $2.6 billion at December 31, 2017 for the U.S. plans and non- U.S. plans, respectively, compared with $1.7 billion and $3.1 billion at December 31, 2016. The increase in the U.S. was primarily due to a decrease in the discount rate used to measure plan liabilities partly offset by investment returns. The decrease in the non-U.S. plans was primarily due to higher investment returns, the impact of assumption changes and the U.K. settlement in the fourth quarter of 2017 as discussed above, partly offset by the impact of a decrease in discount rates and foreign exchange translation. In the past several years, the amount of unamortized losses has been significantly impacted, both positively and negatively, by actual asset performance and changes in discount rates. The discount rate used to measure plan liabilities decreased in both the U.S. and the U.K. (the Company's largest plans) in 2017 and in 2016. The decreases in 2017 and 2016 followed an increase in 2015. An increase in the discount rate decreases the measured plan benefit obligation, resulting in actuarial gains, while a decrease in the discount rate increases the measured plan obligation, resulting in actuarial losses. During 2017, the Company's defined benefit pension plan assets had actual returns of 19.3% and 9.1% in the U.S. and U.K., respectively. During 2016, the Company's defined benefit pension plan assets had actual returns of 9.8% and 22.1% in the U.S. and U.K., respectively. During 2015, the Company's defined benefit pension plan assets had a loss of 3.9% in the U.S. and gain of 1.2% in the U.K. 42 Overall, based on the measurement at December 31, 2017, expenses related to the Company’s defined benefit plans are expected to decrease in 2018 by approximately $90 million compared to 2017. Approximately $80 million of the reduction relates to non-U.S. plans, primarily in the U.K. and in Canada. In the U.K., the net benefit credit was reduced in 2017 by the $54 million settlement charge discussed previously. The recognition of a similar charge in 2018 and the amount of such a charge, if any, is dependent upon whether participant lump sum elections reach or exceed the settlement threshold. The remaining decrease primarily relates to plans in Canada, which ceased the accrual of future benefits on January 1, 2018. Approximately half of the defined benefit expense decrease in Canada will be offset by increased costs for contributions to its defined contribution plans. Historically, service and interest costs were estimated using a single weighted average discount rate derived from the yield curves used to measure the benefit obligations at the beginning of the period. In 2016, the Company changed the approach used to estimate the service and interest cost components of net periodic benefit cost for its significant non-U.S. plans. This change in approach was made to improve the correlation between the projected benefit cash flows and the corresponding yield curve spot rates and to provide a more precise measurement of service and interest costs. The change did not impact the measurement of the plans’ total projected benefit obligation. The Company accounted for this change as a change in estimate, that was applied prospectively beginning in 2016 and resulted in pension expense being approximately $45 million lower than if the prior approach had been used. The Company’s accounting policies for its defined benefit pension plans, including the selection of and sensitivity to assumptions, are discussed below under Management’s Discussion of Critical Accounting Policies. For additional information regarding the Company’s retirement plans, see Note 7 to the consolidated financial statements. In March 2015, the Company amended the RRA, resulting in its termination, with benefits to certain participants to be paid through December 31, 2016. As a result of the termination of the RRA plan, the Company recognized a net credit of approximately $125 million in the first quarter of 2015. Financing Cash Flows Net cash used for financing activities was $1.0 billion in 2017 compared with $1.1 billion used in 2016. Debt The Company increased outstanding debt by approximately $680 million in 2017 and $400 million in 2016. The Company has established a short-term debt financing program of up to $1.5 billion through the issuance of commercial paper. The proceeds from the issuance of commercial paper are used for general corporate purposes. The Company had no commercial paper outstanding at December 31, 2017. In January 2017, the Company issued $500 million of 2.75% senior notes due in 2022 and $500 million of 4.35% senior notes due in 2047. The Company used the net proceeds for general corporate purposes, which included the repayment of a $250 million debt maturity in April 2017. In March 2016, the Company issued $350 million of 3.30% seven-year senior notes. In September 2015, the Company issued $600 million of 3.75% 10.5-year senior notes, and in March 2015, the Company issued $500 million of 2.35% five-year senior notes. The Company used the net proceeds from these issuances for general corporate purposes. Credit Facilities The Company and certain of its subsidiaries maintain a $1.5 billion multi-currency five-year unsecured revolving credit facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. This facility expires in November 2020 and requires the Company to maintain certain coverage and leverage ratios which are tested quarterly. There were no borrowings outstanding under this facility at December 31, 2017. The Company also maintains other credit facilities, guarantees and letters of credit with various banks, aggregating $624 million at December 31, 2017 and $376 million at December 31, 2016. There were no 43 outstanding borrowings under these facilities at December 31, 2017 and $1.6 million of outstanding borrowings under these facilities at December 31, 2016. The Company's senior debt is currently rated A- by Standard & Poor's and Baa1 by Moody's. The Company's short-term debt is currently rated A-2 by Standard & Poor's and P-2 by Moody's. The Company carries a stable outlook from both firms. Share Repurchases During 2017, the Company repurchased 11.5 million shares of its common stock for total consideration of $900 million at an average price per share of $77.93. In November 2016, the Board of Directors authorized an increase in the Company’s share repurchase program, which supersedes any prior authorization, allowing management to buy back up to $2.5 billion of the Company’s common stock going forward. As of December 31, 2017, the Company remained authorized to purchase additional shares of its common stock up to a value of approximately $1.5 billion. There is no time limit on this authorization. During 2016, the Company repurchased 12.7 million shares of its common stock for total consideration of $800 million at an average price per share of $63.18. Dividends The Company paid total dividends of $740 million in 2017 ($1.43 per share), $682 million in 2016 ($1.30 per share) and $632 million in 2015 ($1.18 per share). Contingent Payments Related To Acquisitions During 2017, the Company paid $108 million of contingent payments related to acquisitions made in prior years. These payments are split between financing and operating cash flows in the consolidated statements of cash flows. Payments of $81 million related to the contingent consideration liability that was recorded on the date of acquisition are reflected as financing cash flows. Payments related to increases in the contingent consideration liability subsequent to the date of acquisition of $27 million are reflected as operating cash flows. Remaining estimated future contingent consideration payments of $189 million for acquisitions completed in 2017 and in prior years are included in accounts payable and accrued liabilities or other liabilities in the consolidated balance sheet at December 31, 2017. The Company paid deferred purchase consideration related to prior years' acquisitions of $55 million, $54 million and $36 million in the years ended December 31, 2017, 2016 and 2015, respectively. Remaining deferred cash payments of approximately $121 million are included in accounts payable and accrued liabilities or other liabilities in the consolidated balance sheet at December 31, 2017. In 2016, the Company paid $86 million of contingent payments related to acquisitions made in prior periods, of which $44 million was reported as financing cash flows and $42 million as operating cash flows. In 2015, the Company made $47 million of contingent payments related to acquisitions made in prior periods, of which $13 million was reported as financing cash flows and $34 million as operating cash flows. Investing Cash Flows Net cash used for investing activities amounted to $956 million in 2017 compared with $1.1 billion used for investing activities in 2016. The Company paid $655 million and $813 million, net of cash acquired, for acquisitions it made during 2017 and 2016, respectively. On February 24, 2015, Mercer purchased shares of common stock of Benefitfocus (NASDAQ:BNFT) constituting approximately 9.9% of BNFT's outstanding capital stock as of the acquisition date. The purchase price for the BNFT shares and certain other rights and other consideration was approximately $75 million. In 2015, the Company elected to account for this investment under the cost method of accounting as the shares purchased were categorized as restricted. Effective December 31, 2016, these shares were no longer considered restricted for the purpose of determining if they are marketable securities under GAAP, and are accounted for as available for sale securities and included in other assets in the consolidated balance sheets. 44 The Company’s additions to fixed assets and capitalized software, which amounted to $302 million in 2017 and $253 million in 2016, primarily relate to computer equipment purchases, the refurbishing and modernizing of office facilities and software development costs. The Company has commitments for potential future investments of approximately $57 million in four private equity funds that invest primarily in financial services companies. Commitments and Obligations The following sets forth the Company’s future contractual obligations by the types identified in the table below as of December 31, 2017: Contractual Obligations (In millions of dollars) Current portion of long-term debt Long-term debt Interest on long-term debt Net operating leases Service agreements Other long-term obligations Total Total 262 $ $ 5,261 1,935 2,057 387 338 $ 10,240 $ Payment due by Period Within 1 Year 1-3 Years 4-5 Years 262 $ — 206 314 228 136 1,146 $ — $ — $ 830 384 542 134 185 2,075 $ 1,030 325 429 12 13 1,809 $ After 5 Years — 3,401 1,020 772 13 4 5,210 The above does not include the liability for unrecognized tax benefits of $71 million as the Company is unable to reasonably predict the timing of settlement of these liabilities, other than approximately $1 million that may become payable during 2018. The above does not include net pension liabilities of approximately $1.8 billion because the timing and amount of ultimate payment of such liability is dependent upon future events, including, but not limited to, future returns on plan assets and changes in the discount rate used to measure the liabilities. The above does not include the provisional estimate of transitional tax payments related to the TCJA of $240 million. The amounts of estimated future benefits payments to be made from pension plan assets are disclosed in Note 7 to the consolidated financial statements. In 2018, the Company expects to contribute approximately $27 million and $82 million to its U.S. and non-U.S. defined benefit pension plans, respectively. Management’s Discussion of Critical Accounting Policies The preparation of financial statements in conformity with accounting principles generally accepted in the United States ("GAAP") requires management to make estimates and judgments that affect reported amounts of assets, liabilities, revenue and expenses, and disclosure of contingent assets and liabilities. Management considers the policies discussed below to be critical to understanding the Company’s financial statements because their application places the most significant demands on management’s judgment, and requires management to make estimates about the effect of matters that are inherently uncertain. Actual results may differ from those estimates. Legal and Other Loss Contingencies The Company and its subsidiaries are subject to numerous claims, lawsuits and proceedings including claims for errors and omissions ("E&O"). GAAP requires that a liability be recorded when a loss is both probable and reasonably estimable. Significant management judgment is required to apply this guidance. The Company utilizes case level reviews by inside and outside counsel, an internal actuarial analysis by Oliver Wyman Group, a subsidiary of the Company, and other methods to estimate potential losses. The liability is reviewed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable. Given the unpredictability of E&O claims and of litigation that could flow from them, it is possible that an adverse outcome in a particular matter could have a material adverse effect on the Company’s businesses, results of operations, financial condition or cash flow in a given quarterly or annual period. 45 In addition, to the extent that insurance coverage is available, significant management judgment is required to determine the amount of recoveries that are probable of collection under the Company’s various insurance programs. Retirement Benefits The Company maintains qualified and non-qualified defined benefit pension and defined contribution plans for its eligible U.S. employees and a variety of defined benefit and defined contribution plans for its eligible non-U.S. employees. The Company’s policy for funding its tax-qualified defined benefit retirement plans is to contribute amounts at least sufficient to meet the funding requirements set forth in U.S. and applicable foreign laws. The Company recognizes the funded status of its over-funded defined benefit pension and retiree medical plans as a net benefit plan asset and its unfunded and underfunded plans as a net benefit plan liability. The gains or losses and prior service costs or credits that have not been recognized as components of net periodic costs are recorded as a component of Accumulated Other Comprehensive Income ("AOCI"), net of tax, in the Company’s consolidated balance sheets. The gains and losses that exceed specified corridors are amortized prospectively out of AOCI over a period that approximates the remaining life expectancy of participants in plans where substantially all participants are inactive or the average remaining service period of active participants for plans with active participants. The vast majority of unrecognized losses relate to inactive plans and are amortized over the remaining life expectancy of the participants. The determination of net periodic pension cost is based on a number of assumptions, including an expected long-term rate of return on plan assets, the discount rate, mortality and assumed rate of salary increase. The assumptions used in the calculation of net periodic pension costs and pension liabilities are disclosed in Note 7 to the consolidated financial statements. The assumptions for expected rate of return on plan assets and the discount rate are discussed in more detail below. The long-term rate of return on plan assets assumption is determined for each plan based on the facts and circumstances that exist as of the measurement date, and the specific portfolio mix of each plan’s assets. The Company utilizes a model developed by Mercer, a subsidiary of the Company, to assist in the determination of this assumption. The model takes into account several factors, including: actual and target portfolio allocation; investment, administrative and trading expenses incurred directly by the plan trust; historical portfolio performance; relevant forward-looking economic analysis; and expected returns, variances and correlations for different asset classes. These measures are used to determine probabilities using standard statistical techniques to calculate a range of expected returns on the portfolio. The target asset allocation for the U.S. Plans is 64% equities and equity alternatives and 36% fixed income. At December 31, 2017, the actual allocation for the U.S. Plans was 63% equities and equity alternatives and 37% fixed income. At the end of 2016, the target asset allocation for the U.K. Plans, which comprise approximately 81% of non-U.S. Plan assets, was 48% equities and equity alternatives and 52% fixed income. During 2017, due to improvement in the funded status of the U.K. Plans, the Trustee revised the target asset allocation to 34% equities and equity alternatives and 66% fixed income. At December 31, 2017, the actual allocation for the U.K. Plans was 48% equities and equity alternatives and 52% fixed income and the Company expects to continue to move the actual portfolio allocation toward the revised targets during 2018. The discount rate selected for each U.S. Plan is based on a model bond portfolio with coupons and redemptions that closely match the expected liability cash flows from the plan. Discount rates for non-U.S. plans are based on appropriate bond indices adjusted for duration; in the U.K., the plan duration is reflected using the Mercer yield curve. 46 The table below shows the weighted average assumed rate of return and the discount rate at the December 31, 2017 measurement date (for measuring pension expense in 2018) for the total Company, the U.S. and the Rest of World ("ROW"). Assumed Rate of Return on Plan Assets Discount Rate Total Company 5.83% 3.07% U.S. ROW 7.95% 3.86% 4.94% 2.58% Holding all other assumptions constant, a half-percentage point change in the rate of return on plan assets and discount rate assumptions would affect net periodic pension cost for the U.S. and U.K. plans, which together comprise approximately 85% of total pension plan liabilities, as follows: (In millions of dollars) Assumed Rate of Return on Plan Assets Discount Rate 0.5 Percentage Point Increase 0.5 Percentage Point Decrease U.S. (23) $ (1) $ U.K. (40) $ (3) $ U.S. 23 $ — $ U.K. 40 2 $ $ The impact of discount rate changes shown above relates to the increase or decrease in actuarial gains or losses being amortized through net periodic pension cost, as well as the increase or decrease in interest expense, with all other facts and assumptions held constant. It does not contemplate nor include potential future impacts a change in the interest rate environment and discount rates might cause, such as the impact on the market value of the plans’ assets. Changing the discount rate and leaving the other assumptions constant also may not be representative of the impact on expense, because the long-term rates of inflation and salary increases are often correlated with the discount rate. Changes in these assumptions will not necessarily have a linear impact on the net periodic pension cost. The Company contributes to certain health care and life insurance benefits provided to its retired employees. The cost of these post-retirement benefits for employees in the U.S. is accrued during the period up to the date employees are eligible to retire, but is funded by the Company as incurred. The key assumptions and sensitivity to changes in the assumed health care cost trend rate are discussed in Note 7 to the consolidated financial statements. Income Taxes The Company's tax rate reflects its income, statutory tax rates and tax planning in the various jurisdictions in which it operates. In 2017, the Company's tax expense was significantly impacted by the enactment of the TCJA, which is discussed in more detail in Note 6 to the consolidated financial statements included in this report. Significant judgment is required in determining the annual effective tax rate and in evaluating uncertain tax positions. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The evaluation of a tax position is a two-step process. The first step involves recognition. The Company determines whether it is more likely than not that a tax position will be sustained upon tax examination, including resolution of any related appeals or litigation, based on only the technical merits of the position. The technical merits of a tax position derive from both statutory and judicial authority (legislation and statutes, legislative intent, regulations, rulings, and case law) and their applicability to the facts and circumstances of the tax position. If a tax position does not meet the more-likely-than-not recognition threshold, the benefit of that position is not recognized in the financial statements. The second step is measurement. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate resolution with a taxing authority. Uncertain tax positions are evaluated based upon the facts and circumstances that exist at each reporting period and involve significant management judgment. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition, and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue. 47 Certain items are included in the Company's tax returns at different times than the items are reflected in the financial statements. As a result, the annual tax expense reflected in the consolidated statements of income is different than that reported in the tax returns. Some of these differences are permanent, such as expenses that are not deductible in the returns, and some differences are temporary and reverse over time, such as depreciation expense. Temporary differences create deferred tax assets and liabilities, which are measured at existing tax rates. Deferred tax liabilities generally represent tax expense recognized in the financial statements for which payment has been deferred, or expense for which a deduction has been taken already in the tax return but the expense has not yet been recognized in the financial statements. Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns in future years for which a benefit has already been recorded in the financial statements. The Company evaluates all significant available positive and negative evidence, including the existence of losses in recent years and its forecast of future taxable income by jurisdiction, in assessing the need for a valuation allowance. The Company also considers tax planning strategies that would result in realization of deferred tax assets, and the presence of taxable income in prior period tax filings in jurisdictions that allow for the carryback of tax attributes pursuant to the applicable tax law. The underlying assumptions the Company uses in forecasting future taxable income require significant judgment and take into account the Company's recent performance. The ultimate realization of deferred tax assets is dependent on the generation of future taxable income during the periods in which temporary differences or carry-forwards are deductible or creditable. Valuation allowances are established for deferred tax assets when it is estimated that it is more likely than not that future taxable income will be insufficient to fully use a deduction or credit in that jurisdiction. Fair Value Determinations Goodwill Impairment Testing—The Company is required to assess goodwill and any indefinite-lived intangible assets for impairment annually, or more frequently if circumstances indicate impairment may have occurred. The Company performs the annual impairment test for each of its reporting units during the third quarter of each year. In accordance with applicable accounting guidance, the Company assesses qualitative factors to determine whether it is necessary to perform the two-step goodwill impairment test. The Company considered numerous factors, which included that the fair value of each reporting unit exceeded its carrying value by a substantial margin in its most recent estimate of reporting unit fair values, whether significant acquisitions or dispositions occurred which might alter the fair value of its reporting units, macroeconomic conditions and their potential impact on reporting unit fair values, actual performance compared with budget and prior projections used in its estimation of reporting unit fair values, industry and market conditions, and the year-over-year change in the Company’s share price. The Company completed its qualitative assessment in the third quarter of 2017 and concluded that a two- step goodwill impairment test was not required in 2017 and that goodwill was not impaired. Share-Based Payment The guidance for accounting for share-based payments requires, among other things, that the estimated fair value of stock options be charged to earnings. Significant management judgment is required to determine the appropriate assumptions for inputs such as volatility and expected term necessary to estimate option values. In addition, management judgment is required to analyze the terms of the plans and awards granted thereunder to determine if awards will be treated as equity awards or liability awards, as defined by the accounting guidance. As of December 31, 2017, there was $14.9 million of unrecognized compensation cost related to stock option awards. The weighted-average period over which the costs are expected to be recognized is 1.36 years. Also as of December 31, 2017, there was $197.4 million of unrecognized compensation cost related to the Company’s restricted stock, restricted stock unit and performance stock unit awards. The weighted-average period over which that cost is expected to be recognized is approximately 1.08 years. See Note 8 to the consolidated financial statements for additional information regarding accounting for share-based payments. 48 New Accounting Pronouncements Note 1 to the consolidated financial statements contains a summary of the Company’s significant accounting policies, including a discussion of recently issued accounting pronouncements and their impact or potential future impact on the Company’s financial results, if determinable, under the sub- heading "New Accounting Pronouncements". 49 Item 7A. Quantitative and Qualitative Disclosures About Market Risk Market Risk and Credit Risk Certain of the Company’s revenues, expenses, assets and liabilities are exposed to the impact of interest rate changes and fluctuations in foreign currency exchange rates and equity markets. Interest Rate Risk and Credit Risk Interest income generated from the Company’s cash investments as well as invested fiduciary funds will vary with the general level of interest rates. The Company had the following investments subject to variable interest rates: (In millions of dollars) Cash and cash equivalents invested in money market funds, certificates of deposit and time deposits Fiduciary cash and investments December 31, 2017 $ $ 1,205 4,847 Based on the above balances, if short-term interest rates increased or decreased by 10%, or 11 basis points, over the full year, annual interest income, including interest earned on fiduciary funds, would increase or decrease by approximately $4 million. In addition to interest rate risk, our cash investments and fiduciary fund investments are subject to potential loss of value due to counter-party credit risk. To minimize this risk, the Company and its subsidiaries invest pursuant to a Board approved investment policy. The policy mandates the preservation of principal and liquidity and requires broad diversification with counter-party limits assigned based primarily on credit rating and type of investment. The Company carefully monitors its cash and fiduciary fund investments and will further restrict the portfolio as appropriate to market conditions. The majority of cash and fiduciary fund investments are invested in short-term bank deposits and liquid money market funds. Foreign Currency Risk The translated values of revenue and expense from the Company’s international operations are subject to fluctuations due to changes in currency exchange rates. The non-U.S. based revenue that is exposed to foreign exchange fluctuations is approximately 50% of total revenue. We periodically use forward contracts and options to limit foreign currency exchange rate exposure on net income and cash flows for specific, clearly defined transactions arising in the ordinary course of business. Although the Company has significant revenue generated in foreign locations which is subject to foreign exchange rate fluctuations, in most cases both the foreign currency revenue and expenses are in the functional currency of the foreign location. As such, under normal circumstances, the U.S. dollar translation of both the revenues and expenses, as well as the potentially offsetting movements of various currencies against the U.S. dollar, generally tends to mitigate the impact on net operating income of foreign currency risk. However, there have been periods where the impact was not mitigated due to external market factors, and external macroeconomic events, such as the vote on "Brexit" in the United Kingdom, may result in greater foreign exchange rate fluctuations in the future. If foreign exchange rates of major currencies (Euro, Sterling, Australian dollar and Canadian dollar) moved 10% in the same direction against the U.S. dollar compared with the foreign exchange rates in 2017, the Company estimates net operating income would increase or decrease by approximately $60 million. The Company has exposure to approximately 80 foreign currencies overall. In Continental Europe, the largest amount of revenue from renewals for the Risk & Insurance Services segment occurs in the first quarter. Equity Price Risk The Company holds investments in both public and private companies as well as private equity funds. Investments of approximately $97 million are classified as available for sale, which includes the Company's investment in Benefitfocus. Approximately $62 million are accounted for using the cost method and $405 million are accounted for using the equity method, which includes the Company's 50 investments in Alexander Forbes. The investments are subject to risk of changes in market value, which, if determined to be other than temporary, could result in realized impairment losses. The Company periodically reviews the carrying value of such investments to determine if any valuation adjustments are appropriate under the applicable accounting pronouncements. As of December 31, 2017, the carrying value of the Company’s investment in Alexander Forbes was $266 million. As of December 31, 2017, the market value of the approximately 443 million shares of Alexander Forbes owned by the Company, based on the December 31, 2017 closing share price of 6.87 South African Rand per share, was approximately $239 million. Other A number of lawsuits and regulatory proceedings are pending.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Summary of Significant Accounting Policies Nature of Operations: Marsh & McLennan Companies, Inc. (the "Company"), a global professional services firm, is organized based on the different services that it offers. Under this structure, the Company’s two business segments are Risk and Insurance Services and Consulting. The Risk and Insurance Services segment provides risk management solutions, services, advice and insurance broking, reinsurance broking and insurance program management services for businesses, public entities, insurance companies, associations, professional services organizations, and private clients. The Company conducts business in this segment through Marsh and Guy Carpenter. The Company conducts business in its Consulting segment through Mercer and Oliver Wyman Group. Mercer provides consulting expertise, advice, services and solutions in the areas of health, retirement, talent and investments. Oliver Wyman Group provides specialized management and economic and brand consulting services. Acquisitions impacting the Risk and Insurance Services and Consulting segments are discussed in Note 4 below. Principles of Consolidation: The accompanying consolidated financial statements include all wholly- owned and majority-owned subsidiaries. All significant inter-company transactions and balances have been eliminated. Fiduciary Assets and Liabilities: In its capacity as an insurance broker or agent, generally the Company collects premiums from insureds and after deducting its commissions, remits the premiums to the respective insurance underwriters. The Company also collects claims or refunds from underwriters on behalf of insureds. Unremitted insurance premiums and claims proceeds are held by the Company in a fiduciary capacity. Risk and Insurance Services revenue includes interest on fiduciary funds of $39 million, $26 million and $21 million in 2017, 2016 and 2015, respectively. The Consulting segment recorded fiduciary interest income of $4 million, $3 million and $4 million in 2017, 2016 and 2015, respectively. Since fiduciary assets are not available for corporate use, they are shown in the consolidated balance sheets as an offset to fiduciary liabilities. Net uncollected premiums and claims and the related payables were $6.8 billion and $7 billion at December 31, 2017 and 2016, respectively. The Company is not a principal to the contracts under which the right to receive premiums or the right to receive reimbursement of insured losses arises. Accordingly, net uncollected premiums and claims and the related payables are not assets and liabilities of the Company and are not included in the accompanying consolidated balance sheets. In certain instances, the Company advances premiums, refunds or claims to insurance underwriters or insureds prior to collection. These advances are made from corporate funds and are reflected in the accompanying consolidated balance sheets as receivables. Mercer manages approximately $227 billion of assets in trusts or funds for which Mercer’s management or trustee fee is not considered a variable interest, since the fees are commensurate with the level of effort required to provide those services. Mercer is not the primary beneficiary of these trusts or funds. Mercer’s maximum exposure to loss of its interests is, therefore, limited to collection of its fees. Revenue: Risk and Insurance Services revenue includes insurance commissions, fees for services rendered and interest income on certain fiduciary funds. Insurance commissions and fees for risk transfer services generally are recorded as of the effective date of the applicable policies or, in certain cases (primarily in the Company's reinsurance broking operations), as of the effective date or billing date, whichever is later. A reserve for policy cancellation is provided based on historic and current data on cancellations. Consideration for fee arrangements covering multiple insurance placements, the provision of risk management and/or other services is allocated to all deliverables on the basis of the relative selling prices. Fees for non-risk transfer services provided to clients are recognized over the period in which the services are provided, using a proportional performance model. Fees resulting from achievement of 57 certain performance thresholds are recorded when such levels are attained and such fees are not subject to forfeiture. Consulting revenue includes fees paid by clients for advice and services and commissions from insurance companies for the placement of individual and group contracts. Fee revenue for engagements where remuneration is based on time plus out-of-pocket expenses is recognized based on the amount of time consulting professionals expend on the engagement. For fixed fee engagements, revenue is recognized using a proportional performance model. Revenue from insurance commissions not subject to a fee arrangement is recorded over the effective period of the applicable policies. Revenue for asset based fees is recognized on an accrual basis by applying the daily/monthly rate as contractually agreed with the client to the applicable net asset value. On a limited number of engagements, performance fees may also be earned for achieving certain prescribed performance criteria. Such fees are recognized when the performance criteria have been achieved and, when required, agreed to by the client. Reimbursable expenses incurred by professional staff in the generation of revenue and sub-advisory fees related to the majority of funds in the investment management business are included in revenue and the related expenses are included in other operating expenses. Cash and Cash Equivalents: Cash and cash equivalents primarily consist of certificates of deposit and time deposits, with original maturities of three months or less, and money market funds. The estimated fair value of the Company's cash and cash equivalents approximates their carrying value. The Company is required to maintain operating funds primarily related to regulatory requirements outside the United States or as collateral under captive insurance arrangements. At December 31, 2017, the Company maintained $187 million related to these regulatory requirements. Fixed Assets: Fixed assets are stated at cost less accumulated depreciation and amortization. Expenditures for improvements are capitalized. Upon sale or retirement of an asset, the cost and related accumulated depreciation and amortization are removed from the accounts and any gain or loss is reflected in income. Expenditures for maintenance and repairs are charged to operations as incurred. Depreciation of buildings, building improvements, furniture, and equipment is provided on a straight-line basis over the estimated useful lives of these assets. Furniture and equipment is depreciated over periods ranging from three to ten years. Leasehold improvements are amortized on a straight-line basis over the periods covered by the applicable leases or the estimated useful life of the improvement, whichever is less. Buildings are depreciated over periods ranging from thirty to forty years. The Company periodically reviews long-lived assets for impairment whenever events or changes indicate that the carrying value of assets may not be recoverable. The components of fixed assets are as follows: December 31, (In millions of dollars) Furniture and equipment Land and buildings Leasehold and building improvements Less-accumulated depreciation and amortization 2017 $ 1,179 385 974 2,538 (1,826) 712 $ 2016 $ 1,113 389 906 2,408 (1,683) 725 $ Investments: The Company holds investments in certain private equity funds. Investments in private equity funds are accounted for under the equity method of accounting using a consistently applied three- month lag period adjusted for any known significant changes from the lag period to the reporting date of the Company. The underlying private equity funds follow investment company accounting, where investments within the fund are carried at fair value. Investment gains or losses for its proportionate share of the change in fair value of the funds are recorded in earnings. Investments using the equity method of accounting are included in other assets in the consolidated balance sheets. 58 In 2017, the Company recorded investment income of $15 million compared to less than $1 million in 2016 and $38 million in 2015. The investment income in 2015 was primarily due to general partner carried interest from the Company's investment in Trident III, which was substantially liquidated in 2015. Goodwill and Other Intangible Assets: Goodwill represents acquisition costs in excess of the fair value of net assets acquired. Goodwill is reviewed at least annually for impairment. The Company performs an annual impairment test for each of its reporting units during the third quarter of each year. When a step 1 test is performed, fair values of the reporting units are estimated using either a market approach or a discounted cash flow model. Carrying values for the reporting units are based on balances at the prior quarter end and include directly identified assets and liabilities as well as an allocation of those assets and liabilities not recorded at the reporting unit level. As discussed in Note 5, the Company may elect to assess qualitative factors to determine if a step 1 test is necessary. Other intangible assets, which primarily consist of acquired customer lists, that are not deemed to have an indefinite life, are amortized over their estimated lives, typically ranging from 10 to 15 years, and reviewed for impairment upon the occurrence of certain triggering events in accordance with applicable accounting literature. The Company had no indefinite lived identified intangible assets at December 31, 2017 and 2016. Capitalized Software Costs: The Company capitalizes certain costs to develop, purchase or modify software for the internal use of the Company. These costs are amortized on a straight-line basis over periods ranging from 3 to 10 years. Costs incurred during the preliminary project stage and post implementation stage, are expensed as incurred. Costs incurred during the application development stage are capitalized. Costs related to updates and enhancements are only capitalized if they will result in additional functionality. Capitalized computer software costs of $488 million and $482 million, net of accumulated amortization of $1.3 billion and $1.1 billion at December 31, 2017 and 2016, respectively, are included in other assets in the consolidated balance sheets. Legal and Other Loss Contingencies: The Company and its subsidiaries are subject to a significant number of claims, lawsuits and proceedings including claims for errors and omissions ("E&O"). The preparation of financial statements in conformity with accounting principles generally accepted in the United States ("GAAP") requires that a liability be recorded when a loss is both probable and reasonably estimable. Significant management judgment is required to apply this guidance. The Company utilizes case level reviews by inside and outside counsel, an internal actuarial analysis by Oliver Wyman Group, a subsidiary of the Company, and other methods to estimate potential losses. The liability is reviewed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable. Given the unpredictability of E&O claims and of litigation that could flow from them, it is possible that an adverse outcome in a particular matter could have a material adverse effect on the Company’s businesses, results of operations, financial condition or cash flow in a given quarterly or annual period. In addition, to the extent that insurance coverage is available, significant management judgment is required to determine the amount of recoveries that are probable of collection under the Company’s various insurance programs. The legal and other contingent liabilities described above are not discounted. Income Taxes: The Company's effective tax rate reflects its income, statutory tax rates and tax planning in the various jurisdictions in which it operates. Significant judgment is required in determining the annual tax provision and in evaluating uncertain tax positions and the ability to realize deferred tax assets. Specific considerations related to the enactment of U.S. tax reform are discussed in more detail in Note 6 to the consolidated financial statements. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company determines whether it is more likely than not that a tax position will be sustained upon tax examination, including resolution of any related appeals or litigation, based on only the technical merits of the position. The technical merits of a tax position derive from both statutory and judicial authority (legislation and statutes, legislative intent, regulations, rulings, and case law) and their applicability to the facts and circumstances of the tax position. If a tax position 59 does not meet the more-likely-than-not recognition threshold, the benefit of that position is not recognized in the financial statements. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon ultimate resolution with a taxing authority. Uncertain tax positions are evaluated based upon the facts and circumstances that exist at each reporting period. Subsequent changes in judgment based upon new information may lead to changes in recognition, de-recognition, and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense. Tax law may require items be included in the Company's tax returns at different times than the items are reflected in the financial statements. As a result, the annual tax expense reflected in the consolidated statements of income is different than that reported in the income tax returns. Some of these differences are permanent, such as expenses that are not deductible in the returns, and some differences are temporary and reverse over time, such as depreciation expense. Temporary differences create deferred tax assets and liabilities. Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns in future years for which benefit has already been recorded in the financial statements. Valuation allowances are established for deferred tax assets when it is estimated that future taxable income will be insufficient to use a deduction or credit in that jurisdiction. Deferred tax liabilities generally represent tax expense recognized in the financial statements for which payment has been deferred, or expense for which a deduction has been taken already in the tax return but the expense has not yet been recognized in the financial statements. Derivative Instruments: All derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. The fair value of the derivative is recorded in the consolidated balance sheet in other receivables or accounts payable and accrued liabilities. The change in the fair value of a derivative is recorded in the consolidated statement of income in other operating expenses. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive income and are recognized in the income statement when the hedged item affects earnings. Changes in the fair value attributable to the ineffective portion of cash flow hedges are recognized in earnings. Concentrations of Credit Risk: Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, commissions and fees receivable and insurance recoverables. The Company maintains a policy providing for the diversification of cash and cash equivalent investments and places its investments in a large number of high quality financial institutions to limit the amount of credit risk exposure. Concentrations of credit risk with respect to receivables are generally limited due to the large number of clients and markets in which the Company does business, as well as the dispersion across many geographic areas. Per Share Data: Basic net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income attributable to common shares by the weighted average number of outstanding shares of the Company’s common stock. Diluted net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income attributable to common shares by the weighted average number of outstanding shares of the Company’s common stock, which have been adjusted for the dilutive effect of potentially issuable common shares. Reconciliations of the applicable components used to calculate basic and diluted EPS - Continuing Operations are presented below. The reconciling items related to the EPS calculation are the same for both basic and diluted EPS. 60 Basic and Diluted EPS Calculation - Continuing Operations (In millions, except per share figures) Net income from continuing operations Less: Net income attributable to non-controlling interests Basic weighted average common shares outstanding Dilutive effect of potentially issuable common shares Diluted weighted average common shares outstanding Average stock price used to calculate common stock equivalents 20 27 2017 2016 2015 $ 1,510 $ 1,795 $ 1,636 37 $ 1,490 $ 1,768 $ 1,599 531 5 536 $ 77.30 $ 63.51 $ 56.27 513 6 519 519 5 524 There were 10.2 million, 13.2 million and 14.8 million stock options outstanding as of December 31, 2017, 2016 and 2015, respectively. Estimates: GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may vary from those estimates. New Accounting Pronouncements Recently Adopted: In October 2016, the FASB issued new guidance which changes the evaluation of whether a reporting entity is the primary beneficiary of a variable interest entity by changing how a reporting entity that is a single decision maker of a variable interest entity treats indirect interests in the entity held through related parties that are under common control with the reporting entity. If a reporting entity satisfies the first characteristic of a primary beneficiary (such that it is the single decision maker of a variable interest entity), the new guidance requires that reporting entity, in determining whether it satisfies the second characteristic of a primary beneficiary, include all of its direct variable interest in a variable interest entity and, on a proportionate basis, its indirect variable interests in a variable interest entity held through related parties, including related parties that are under common control with the reporting entity. The adoption of this guidance did not have a significant impact on its financial position, results of operations and statement of cash flows. In April 2016, the FASB issued new guidance which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The new guidance requires that companies record all excess tax benefits and tax deficiencies as an income tax benefit or expense in the income statement and classify excess tax benefits as an operating activity in the statement of cash flows. The Company adopted this new guidance prospectively, effective January 1, 2017 and prior periods have not been adjusted. For the year ended December 31, 2017, the adoption of this new standard reduced income tax expense in the consolidated statement of income by approximately $79 million. For the years ended December 31, 2016 and 2015, the Company recorded an excess tax benefit of $44 million and $53 million, respectively, as an increase to equity in its consolidated balance sheets, which was reflected as cash provided by financing activities in the consolidated statements of cash flows. In March 2016, the FASB issued new guidance which eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The 61 new guidance is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The guidance was adopted on January 1, 2017 and did not have an impact on the Company's financial position or results of operations. In September 2015, the FASB issued new guidance intended to simplify the accounting for adjustments made to provisional amounts recognized in business combinations. The guidance requires the acquirer to recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustments are determined, and to record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed as of the acquisition date. The guidance also requires additional disclosures required for the amounts recorded in current period earnings arising from such adjustments. The guidance was adopted on January 1, 2016 and did not have a material impact on the Company's financial position or results of operations. In May 2015, the FASB issued new guidance which removes the requirement to present certain investments for which the practical expedient is used to measure fair value at net asset value within the fair value hierarchy table. Instead, an entity is required to include those investments as a reconciling item so that the total fair value amount of investments in the disclosure is consistent with the fair value investment balance in the consolidated balance sheets. This guidance is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The adoption of this new guidance affected footnote disclosure only, and therefore did not have a material impact on the Company's financial position or results of operations. In February 2015, the FASB issued new accounting guidance intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations and securitization structures. The guidance focuses on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. The guidance is effective for periods beginning after December 15, 2015. The adoption of this guidance did not have a material impact on the Company's financial statements. In January 2015, the FASB issued new accounting guidance that eliminated the concept of extraordinary items. The guidance is effective for annual periods beginning after December 15, 2015. Adoption of the guidance did not materially affect the Company's financial condition, results of operations or cash flows. New Accounting Pronouncements Effective January 1, 2018: New Revenue Recognition Pronouncement In May 2014, the FASB issued new accounting guidance related to revenue from contracts with customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted the new guidance effective January 1, 2018, using the modified retrospective method, which applies the new guidance beginning with the year of adoption, with the cumulative effect of initially applying the guidance recognized as an adjustment to retained earnings at January 1, 2018. The Company elected to apply the modified retrospective method to all contracts. The guidance includes requirements to estimate variable or contingent consideration to be received, which will result in revenue being recognized earlier than under legacy GAAP. In addition, the guidance requires the capitalization and amortization of certain costs which were expensed as incurred under legacy GAAP. As discussed in more detail below, the adoption of this new revenue recognition standard will shift revenue among quarters from historical patterns, but is not expected to have a significant year- over-year impact on annual revenue. In the Risk and Insurance Services segment, there will be significant movement in the quarterly timing of revenue recognition. In particular, under the new standard the recognition of revenue in the Company’s reinsurance broking operations will be accelerated from historical patterns. Prior to the adoption of this standard, revenue related to most reinsurance placements was recognized on the later of billing or effective date as premiums are determined by the primary insurers and attached to the reinsurance treaties. 62 Typically, this resulted in revenue being recognized over a 12 to 24 month period. Under the new guidance, estimated revenue from these treaties will be recognized largely at the policy effective date. In the insurance brokerage operations, revenue from commission based arrangements will continue to be recorded at the policy effective date, while the timing of revenue recognition for certain fee based arrangements will shift among quarters. However, since the vast majority of our fee arrangements involve contracts that cover a single year of services, the Company does not expect there will be a significant change in the amount of revenue recognized in an annual period. In the Risk and Insurance Services segment, certain pre-placement costs will be deferred and amortized into earnings when the revenue from the placement is recognized. These costs were previously expensed as incurred. As such, the Company expects the recognition of costs to shift among quarters. In the Consulting segment, the adoption of the new revenue standard will not have a significant impact on the timing of revenue recognition in quarterly or annual periods. In its Consulting segment, the Company incurs implementation costs necessary to facilitate the delivery of the contracted services. Although certain implementation costs are deferred under current GAAP, the Company has concluded that certain additional implementation costs currently expensed under legacy GAAP will be deferred under the new guidance. In addition, the amortization period for these implementation costs will be longer under the new guidance as the amortization period will include the initial contract term plus expected renewals. Currently, deferred implementation costs are amortized over the initial contract term. The cumulative effect of adopting the standard, net of tax, on January 1, 2018 are expected to result in an increase to the opening balance of retained earnings of approximately $325 million to $425 million, with offsetting increases/decreases to other balance sheet accounts, e.g. accounts receivable, other assets and deferred income taxes. The comparative information and prior periods will not be restated and will continue to be reported under the legacy accounting standards that were in effect for those periods. Other Standards Adopted Effective January 1, 2018 In March 2017, the FASB issued new guidance that changes the presentation of net periodic pension cost and net periodic postretirement cost (''net periodic benefit costs"). The new guidance requires employers to report the service cost component of net periodic benefit costs in the same line item as other compensation costs in the income statement. The other components of net periodic benefit costs are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. In addition, only the service cost component is eligible for capitalization, when applicable. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The new guidance requires retrospective application for the presentation of the service cost component and the other components of net periodic benefit costs as discussed in more detail below, and prospective application for the capitalization of the service cost component. The adoption of this guidance will impact the line item presentation of the Company's results of operations, and will not change income before taxes, net income or earnings per share. When the Company files its financial statements for 2018, the consolidated statements of income for 2017 and 2016 will include the following reclassification: Risk and Insurance Services Consulting Corporate Increase in Compensation and Benefits Other Net Periodic Benefit Credit Net Impact of Reclassification $ $ $ 2017 140 64 (3) 201 (201) — $ 2016 172 65 (4) 233 (233) — In January 2016, the FASB issued new guidance intended to improve the recognition and measurement of financial instruments. The new guidance requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be 63 measured at fair value with changes in fair value recognized in net income; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements; eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; and requires a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (also referred to as "own credit") when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. The new guidance is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company holds certain equity investments that are currently treated as available for sale securities, whereby the mark to market change is recorded to other comprehensive income in its consolidated balance sheet. The Company adopted the new accounting guidance prospectively, effective January 1, 2018, recording a cumulative-effect adjustment increase to retained earnings as of the beginning of the period of adoption of $14 million, reflecting the reclassification of cumulative unrealized gains, net of tax as of December 31, 2017 from other comprehensive income to retained earnings. Therefore, prior periods have not been restated. In October 2016, the FASB also issued new guidance which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The new guidance eliminates the exception for an intra-entity transfer of an asset other than inventory. The new guidance is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new guidance must be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Company adopted the new guidance prospectively, effective January 1, 2018, recording a cumulative-effect adjustment increase to retained earnings of approximately $15 million as of the beginning of the period of adoption. In November 2016, the FASB issued new guidance which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. As a result, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new guidance is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The guidance must be applied retrospectively to all periods presented. Early adoption is permitted. The Company does not expect the adoption of this guidance to impact the Company's consolidated balance sheets or consolidated statements of cash flows. In August 2016, the FASB issued new guidance which adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows, including cash payments for debt prepayments or debt extinguishment costs, contingent consideration payments made after a business combination and distributions received from equity method investees. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The guidance must be applied retrospectively to all periods presented unless retrospective application is impracticable. The Company does not expect the adoption of this guidance to impact the Company's consolidated statements of cash flows. In January 2017, the FASB issued guidance which clarifies the definition of a business in order to assist companies with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The Company does not expect the adoption of this standard to have an impact on the Company's financial position or results of operations. 64 New Accounting Pronouncements Not Yet Adopted: In January 2017, the FASB issued new guidance to simplify the test for goodwill impairment. The new guidance eliminates the second step in the current two-step goodwill impairment process, under which a goodwill impairment loss is measured by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill for that reporting unit. The new guidance requires a one-step impairment test, in which the goodwill impairment charge is based on the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The guidance should be applied on a prospective basis with the nature of and reason for the change in accounting principle disclosed upon transition. The guidance is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company does not expect the adoption of this standard to have a material impact on its financial position or results of operations. In February 2016, the FASB issued new guidance intended to improve financial reporting for leases. Under the new guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a financing or operating lease. However, unlike current GAAP, which requires that only capital leases be recognized on the balance sheet, the new guidance requires that both types of leases be recognized on the balance sheet. The new guidance will require additional disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative requirements, and additional information about the amounts recorded in the financial statements. The accounting by organizations that own the assets ("lessor") leased by the lessee will remain largely unchanged from current GAAP. However, the guidance contains targeted improvements that are intended to align, where necessary, lessor accounting with the lessee accounting model. The new guidance on leases is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early application is permitted. The Company is currently evaluating the impact the adoption of the guidance will have on its financial position and results of operations, but expects material "right to use" assets and lease liabilities to be recorded on its consolidated balance sheets. 2.

Acquisitions / Dispositions The Company’s acquisitions have been accounted for as business combinations. Net assets and results of operations are included in the Company’s consolidated financial statements commencing at the respective purchase closing dates. In connection with acquisitions, the Company records the estimated value of the net tangible assets purchased and the value of the identifiable intangible assets purchased, which typically consist of purchased customer lists, trademarks and non-compete agreements. The valuation of purchased intangible assets involves significant estimates and assumptions. Until final valuations are complete, any change in assumptions could affect the carrying value of tangible assets, goodwill and identifiable intangible assets. The Risk and Insurance Services segment completed seven acquisitions during 2017. • January – Marsh & McLennan Agency ("MMA") acquired J. Smith Lanier & Co. ("JSL"), a privately held insurance brokerage firm providing insurance, risk management, and employee benefits solutions to businesses and individuals throughout the U.S. • February – MMA acquired iaConsulting, a Texas-based employee benefits consulting firm. • March – MMA acquired Blakestad, Inc., a Minnesota-based private client and commercial lines insurance agency, and RJF Financial Services, a Minnesota-based retirement advisory firm. • May – MMA acquired Insurance Partners of Texas, a Texas-based employee benefits consulting firm. • August – Marsh acquired International Catastrophe Insurance Managers, LLC, a Colorado-based managing general agent providing property catastrophe insurance to business and homeowners, and MMA acquired Hendrick & Hendrick, Inc., a Texas-based insurance agency.

Total purchase consideration for acquisitions made during 2017 was approximately $777 million, which consisted of cash paid of $668 million and deferred purchase and estimated contingent consideration of $109 million. Contingent consideration arrangements are based primarily on EBITDA and/or revenue targets over periods of two to four years. The fair value of the contingent consideration was based on projected revenue and earnings of the acquired entities. Estimated fair values of assets acquired and liabilities assumed are subject to adjustment when purchase accounting is finalized. During 2017, the Company also paid $55 million of deferred purchase consideration and $108 million of contingent consideration related to acquisitions made in prior years. 70 The following table presents the preliminary allocation of the acquisition cost to the assets acquired and liabilities assumed, based on their fair values: (In millions) Cash Estimated fair value of deferred/contingent consideration Total consideration Allocation of purchase price: Cash and cash equivalents Accounts receivable, net Other current assets Property, plant, and equipment Other intangible assets Goodwill Other assets Total assets acquired Current liabilities Other liabilities Total liabilities assumed Net assets acquired 2017 668 109 777 13 30 6 6 304 551 1 911 25 109 134 777 $ $ $ $ Other intangible assets acquired are based on initial estimates and subject to change based on final valuations during the measurement period post acquisition date.

Acquisition-related expenses incurred in 2017 and 2016 were $3 million and $14 million, respectively. 72 Dispositions In December 2015, Mercer sold its U.S. defined contribution recordkeeping business. The Company recognized pre-tax gains of $37 million in 2015 and $6 million in 2016 from this transaction, which are included in revenue in the consolidated statements of income in those years. 5. Goodwill and Other Intangibles The Company is required to assess goodwill and any indefinite-lived intangible assets for impairment annually, or more frequently if circumstances indicate impairment may have occurred. The Company performs the annual impairment assessment for each of its reporting units during the third quarter of each year. In accordance with applicable accounting guidance, the Company assesses qualitative factors to determine whether it is necessary to perform the two-step goodwill impairment test. As part of its assessment, the Company considers numerous factors, including that the fair value of each reporting unit exceeds its carrying value by a substantial margin based on its most recent estimates, whether significant acquisitions or dispositions occurred which might alter the fair value of its reporting units, macroeconomic conditions and their potential impact on reporting unit fair values, actual performance compared with budget and prior projections used in its estimation of reporting unit fair values, industry and market conditions, and the year-over-year change in the Company’s share price. The Company completed its qualitative assessment in the third quarter of 2017 and concluded that a two-step goodwill impairment test was not required in 2017 and that goodwill was not impaired. Other intangible assets that are not deemed to have an indefinite life are amortized over their estimated lives and reviewed for impairment upon the occurrence of certain triggering events in accordance with applicable accounting literature. The Company concluded that these intangible assets are not impaired. Changes in the carrying amount of goodwill are as follows: (In millions of dollars) Balance as of January 1, as reported Goodwill acquired Other adjustments(a) Balance at December 31, 2017 $ 8,369 551 169 $ 9,089 2016 $ 7,889 556 (76) $ 8,369 (a) Primarily due to the impact of foreign exchange in both years. The goodwill acquired of $551 million in 2017 (approximately $9 million of which is deductible for tax purposes) is comprised of $522 million related to the Risk and Insurance Services segment and $29 million related to the Consulting segment. Goodwill allocable to the Company’s reportable segments is as follows: Risk and Insurance Services, $6.5 billion and Consulting, $2.6 billion. The gross cost and accumulated amortization at December 31, 2017 and 2016 are as follows: (In millions of dollars) 2017 2016 Client relationships Other (a) Amortized intangibles Gross Cost $ 1,672 $ 234 $ 1,906 $ Accumulated Amortization Net Carrying Amount Gross Cost Accumulated Amortization 518 $ 114 632 $ 1,154 $ 1,390 $ 120 204 1,274 $ 1,594 $ Net Carrying Amount 998 128 468 $ 1,126 392 $ 76 (a) Primarily non-compete agreements, trade names and developed technology. 73 Aggregate amortization expense was $169 million for the year ended December 31, 2017, $130 million for the year ended December 31, 2016 and $109 million for the year ended December 31, 2015. The estimated future aggregate amortization expense is as follows: For the Years Ending December 31, (In millions of dollars) 2018 2019 2020 2021 2022 Subsequent years 6. Income Taxes $ 180 170 149 139 125 511 $ 1,274 The tax information presented below includes a provisional estimate of the impact of the enactment, in December 2017, of U.S. tax legislation commonly known as the Tax Cuts and Job Act (the "TCJA"), which is discussed in more detail below. For financial reporting purposes, income before income taxes includes the following components: For the Years Ended December 31, (In millions of dollars) Income before income taxes: U.S. Other The expense for income taxes is comprised of: Current– U.S. Federal Other national governments U.S. state and local Deferred– U.S. Federal Other national governments U.S. state and local Total income taxes 2017 2016 2015 $ 819 1,824 $ 2,643 $ 725 1,755 $ 2,480 $ 702 1,605 $ 2,307 $ 313 388 36 737 286 72 38 396 $ 1,133 $ $ 208 366 43 617 26 32 10 68 685 $ $ 90 385 52 527 125 15 4 144 671 74 The significant components of deferred income tax assets and liabilities and their balance sheet classifications are as follows: December 31, (In millions of dollars) Deferred tax assets: Accrued expenses not currently deductible Differences related to non-U.S. operations (a) Accrued U.S. retirement benefits Net operating losses (b) Income currently recognized for tax Other Deferred tax liabilities: Differences related to non-U.S. operations Depreciation and amortization Accrued retirement & postretirement benefits - non-U.S. operations Other 2017 2016 $ 369 139 394 67 49 31 $ 1,049 $ 582 127 629 56 71 50 $ 1,515 $ $ 235 338 172 16 761 $ $ 217 377 10 14 618 (a) Net of valuation allowances of $18 million in 2017 and $3 million in 2016.

December 31, (In millions of dollars) Balance sheet classifications: Deferred tax assets Other liabilities 2017 2016 $ $ 669 381 $ 1,097 200 $ A reconciliation from the U.S. Federal statutory income tax rate to the Company’s effective income tax rate is shown below: For the Years Ended December 31, U.S. Federal statutory rate U.S. state and local income taxes—net of U.S. Federal income tax benefit Differences related to non-U.S. operations U.S. Tax Reform Equity compensation Other Effective tax rate 2017 35.0% 1.5 (8.6) 17.4 (2.6) 0.2 42.9% 2016 35.0% 1.5 (9.2) — — 0.3 27.6% 2015 35.0% 1.6 (8.0) — — 0.5 29.1% The Company’s consolidated effective tax rate was 42.9%, 27.6% and 29.1% in 2017, 2016 and 2015, respectively. The tax rate in each year reflects foreign operations, which are generally taxed at rates lower than the U.S. statutory tax rate. The effective tax rate in 2017 reflects a provisional estimate of the impact of the enactment of the TCJA, as well as the impact of the required change in accounting for equity awards. As a result of TCJA, two discrete charges were recorded. The transition to the new territorial tax system resulted in a transition tax payable over eight years on undistributed earnings of non-U.S. subsidiaries. This mandatory taxation of accumulated foreign earnings substantially changed the economic considerations of continued permanent investment of those accumulated earnings, a key component of 75 our global capital strategy. As a result of the transition tax, the Company anticipates repatriating the majority of the accumulated earnings that it previously intended to permanently invest. A charge of $240 million was recorded in the fourth quarter as a provisional estimate of the transition tax and ancillary effects. The provisional estimate of transition tax includes state taxes and foreign withholding taxes related to the change in the Company's indefinite reinvestment assertion with respect to our pre-2018 foreign earnings. The Company previously considered most unremitted earnings of our non-U.S. subsidiaries, except amounts repatriated in the year earned, to be permanently reinvested and, accordingly, recorded no deferred U.S. income taxes on such earnings. The Company has initially analyzed our global capital requirements and potential tax liabilities attributable to repatriation. The Company estimates that it will repatriate $3.4 billion that was previously considered indefinitely invested. Included in the $240 million charge is a $53 million provisional estimate for withholding and state income taxes. These estimates may be adjusted during 2018 after the Company has finalized its analysis of all the relevant information. U.S. federal income taxes are not provided on the excess of the amount for financial reporting over the tax basis of investments in foreign subsidiaries that are essentially permanent in duration. The determination of the unrecognized deferred tax liability with respect to these investments is not practicable. In addition, reducing the U.S. corporate tax rate from 35% to 21%, and the change in deductibility of certain compensation awards to executive officers of the Company effective on January 1, 2018, resulted in a net charge of $220 million to reduce the value of our U.S. deferred tax assets and liabilities. In December of 2017, the SEC issued Staff Accounting Bulletin 118 ("SAB 118"), establishing a one-year measurement period to complete the accounting for the income tax effects of the TCJA. SAB 118 anticipates three alternative states of completion at the end of the reporting period of accounting for these effects: (1) the tax accounting work has been completed with respect to an item; (2) a provisional amount has been recognized because a reasonable estimate was possible, or (3) a reasonable estimate cannot be provided. The Company believes its analysis of the TCJA to date provides an appropriate basis to record a provisional estimate. Our provisional estimates include the effects of the deemed repatriation tax and the Company's position with respect to permanently reinvested earnings, the impacts of the Global Intangible Low Taxed Income ("GILTI") and Base Erosion and Anti-abuse Tax ("BEAT") provisions, and the remeasurement of U.S. deferred tax based on estimated enactment-date deferred tax balances, which may be adjusted in 2018 when the 2017 tax return is filed. However, given the significant complexity of the TCJA, anticipated guidance from the U.S. Treasury about its implementation, the potential for additional guidance from the SEC or FASB, and the global complexity of the Company, these estimates may be adjusted during 2018. Valuation allowances had net increases of $9 million in 2017 and net decreases of $8 million and $69 million in 2016 and 2015, respectively. During 2017, adjustments of the beginning of the year balances of valuation allowances increased income tax expense by $11 million, and decreased income tax expense by $7 million and $14 million in 2016, and 2015, respectively. The decrease in the valuation allowance in 2015 also reflects the write down of a deferred tax asset along with its full valuation allowance because the Company cannot utilize a net operating loss. Approximately 81% of the Company’s net operating loss carryforwards expire from 2018 through 2036, and others are unlimited. The potential tax benefit from net operating loss carryforwards at the end of 2017 comprised federal, state and local, and non-U.S. tax benefits of $6 million, $49 million and $31 million, respectively, before reduction for valuation allowances. The realization of deferred tax assets depends on generating future taxable income during the periods in which the tax benefits are deductible or creditable. Tax liabilities are determined and assessed jurisdictionally by legal entity or filing group. Certain taxing jurisdictions allow or require combined or consolidated tax filings. The Company assessed the realizability of its deferred tax assets, and considered all available evidence, including the existence of a recent history of losses, placing particular weight on evidence that could be objectively verified. A valuation allowance was recorded to reduce deferred tax assets to the amount that the Company believes is more likely than not to be realized. 76 Following is a reconciliation of the Company’s total gross unrecognized tax benefits for the years ended December 31, 2017, 2016 and 2015: (In millions of dollars) Balance at January 1, Additions, based on tax positions related to current year Additions for tax positions of prior years Reductions for tax positions of prior years Settlements Lapses in statutes of limitation Balance at December 31, 2017 65 1 14 (6) — (3) 71 $ $ 2016 74 2 6 (6) (7) (4) 65 $ $ 2015 97 3 22 (10) (20) (18) 74 $ $ Of the total unrecognized tax benefits at December 31, 2017, 2016 and 2015, $56 million, $53 million and $53 million, respectively, represent the amount that, if recognized, would favorably affect the effective tax rate in any future periods. The total gross amount of accrued interest and penalties at December 31, 2017, 2016 and 2015, before any applicable federal benefit, was $12 million, $11 million and $8 million, respectively. The Company is routinely examined by tax authorities in the jurisdictions in which it has significant operations. In the US federal jurisdiction the Company participates in the Internal Revenue Service’s ("IRS") Compliance Assurance Process ("CAP"), which is structured to conduct real-time compliance reviews. The IRS is currently examining the Company’s 2015 and 2016 tax returns and is performing a pre-filing review of 2017. In 2015, the Company settled its federal tax audit for the year 2014. New York State and New York City have examinations underway for various entities covering the years 2007 through 2014. Outside the United States, there are ongoing examinations in Germany for the years 2009 through 2012, in France for the years 2011 and 2012, and in Italy for the year 2015. There are ongoing examinations in Canada of tax years 2013 and 2014. The United Kingdom's examination of year 2014 is ongoing and an examination of year 2015 has been commenced. The Company regularly considers the likelihood of assessments in each of the taxing jurisdictions resulting from examinations. The Company has established liabilities for uncertain tax positions in relation to the potential assessments. The Company believes the resolution of tax matters will not have a material effect on the consolidated financial position of the Company, although a resolution of tax matters could have a material impact on the Company's net income or cash flows and on its effective tax rate in a particular future period. It is reasonably possible that the total amount of unrecognized tax benefits will decrease between zero and approximately $6 million within the next twelve months due to settlement of audits and expiration of statutes of limitation. 77 7. Retirement Benefits The Company maintains qualified and non-qualified defined benefit pension plans for its U.S. and non- U.S. eligible employees. The Company’s policy for funding its tax qualified defined benefit retirement plans is to contribute amounts at least sufficient to meet the funding requirements set forth by U.S. law and the laws of the non-U.S. jurisdictions in which the Company offers defined benefit plans. Combined U.S. and non-U.S. Plans The weighted average actuarial assumptions utilized for the U.S. and significant non-U.S. defined benefit plans and postretirement benefit plans are as follows: Weighted average assumptions: Discount rate (for expense) Expected return on plan assets Rate of compensation increase (for expense) Discount rate (for benefit obligation) Rate of compensation increase (for benefit obligation)* Pension Benefits Postretirement Benefits 2017 2016 2017 2016 3.40% 6.64% 1.77% 3.07% 4.10% 7.06% 2.44% 3.40% 3.64% — — 3.21% 4.12% — — 3.64% 1.73% 1.77% — — *The 2017 and 2016 assumption do not include a rate of compensation increase for the U.S. defined benefit plans since future benefit accruals were discontinued for those plans after December 31, 2016. The Company uses actuaries from Mercer, a subsidiary of the Company, to perform valuations of its pension plans. The long-term rate of return on plan assets assumption is determined for each plan based on the facts and circumstances that exist as of the measurement date, and the specific portfolio mix of each plan’s assets. The Company utilizes a model developed by the Mercer actuaries to assist in the determination of this assumption. The model takes into account several factors, including: actual and target portfolio allocation; investment, administrative and trading expenses incurred directly by the plan trust; historical portfolio performance; relevant forward-looking economic analysis; and expected returns, variances and correlations for different asset classes. These measures are used to determine probabilities using standard statistical techniques to calculate a range of expected returns on the portfolio. Generally, the Company does not adjust the rate of return assumption from year to year if, at the measurement date, it is within the range between the 25th and 75th percentile of the expected long-term annual returns. Historical long-term average asset returns of the most significant plans are also reviewed to determine whether they are consistent and reasonable compared with the rate selected. The expected return on plan assets is determined by applying the assumed long-term rate of return to the market- related value of plan assets. This market-related value recognizes investment gains or losses over a five- year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return based on the market value of assets. Since the market-related value of assets recognizes gains or losses over a five-year period, the future market-related value of the assets will be impacted as previously deferred gains or losses are reflected. The target asset allocation for the U.S. Plans is 64% equities and equity alternatives and 36% fixed income. At the end of 2017, the actual allocation for the U.S. Plans was 63% equities and equity alternatives and 37% fixed income. The target asset allocation for the U.K. Plans, which comprise approximately 81% of non-U.S. Plan assets, is 34% equities and equity alternatives and 66% fixed income. At the end of 2017, the actual allocation for the U.K. Plans was 48% equities and equity alternatives and 52% fixed income. The assets of the Company's defined benefit plans are diversified and are managed in accordance with applicable laws and with the goal of maximizing the plans' real return within acceptable risk parameters. The Company uses threshold-based portfolio re-balancing to ensure the actual portfolio remains consistent with target asset allocation ranges. The Company reduced the U.K. Plans' target asset allocation to equity and equity alternatives to 34% effective December 31, 2017. The re-balancing took place in early January 2018. 78 The discount rate selected for each U.S. plan is based on a model bond portfolio with coupons and redemptions that closely match the expected liability cash flows from the plan. Discount rates for non-U.S. plans are based on appropriate bond indices adjusted for duration; in the U.K., the plan duration is reflected using the Mercer yield curve. The components of the net periodic benefit cost for defined benefit and other postretirement plans are as follows: Combined U.S. and significant non-U.S. Plans For the Years Ended December 31, Pension Benefits Postretirement Benefits (In millions of dollars) Service cost Interest cost Expected return on plan assets Amortization of prior service (credit) cost Recognized actuarial loss (gain) Net periodic benefit (credit) cost Curtailment (loss) gain Plan termination Settlement loss Total (credit) cost Pension Settlement Charge 2017 2016 2015 2017 2016 2015 $ 76 $ 178 $ 196 $ 1 $ 2 $ 497 537 587 (921) (940) (977) (2) 167 (1) 168 (1) 271 4 — 1 — 5 — 4 (2) $ (183) $ (58) $ 76 $ 6 $ 9 $ (1) — 54 (4) — — 5 — 1 — — — — — — 3 5 — 3 (1) 10 — (128) — $ (130) $ (62) $ 82 $ 6 $ 9 $ (118) Defined Benefit Pension Plans in the U.K. allow participants an option for the payment of a lump sum distribution from plan assets before retirement in full satisfaction of the retirement benefits due to the participant as well as any survivor’s benefit. The Company’s policy under applicable U.S. GAAP is to treat these lump sum payments as a partial settlement of the plan liability if they exceed the total of interest plus service costs ("settlement thresholds"). Based on the amount of lump sum payments through December 31, 2017, the lump sum payments exceeded the settlement thresholds in two of the U.K. plans. This resulted in a non-cash settlement charge of $54 million which was recorded in December 2017. Plan Assets For the U.S. Plans, investment allocation decisions are made by a fiduciary committee composed of senior executives appointed by the Company’s Chief Executive Officer. For the non-U.S. plans, investment allocation decisions are made by local fiduciaries, in consultation with the Company for the larger plans. Plan assets are invested in a manner consistent with the fiduciary standards set forth in all relevant laws relating to pensions and trusts in each country. Primary investment objectives are (1) to achieve an investment return that, in combination with current and future contributions, will provide sufficient funds to pay benefits as they become due, and (2) to minimize the risk of large losses. The investment allocations are designed to meet these objectives by broadly diversifying plan assets among numerous asset classes with differing expected returns, volatilities, and correlations. The major categories of plan assets include equity securities, equity alternative investments, and fixed income securities. For the U.S. Plan, the category ranges are 59-69% for equities and equity alternatives, and 31-41% for fixed income. For the U.K. Plans, the category ranges are 35-41% for equities and equity alternatives, and 59-65% for fixed income. Asset allocation is monitored frequently and re-balancing actions are taken as appropriate. Plan investments are exposed to stock market, interest rate, and credit risk. Concentrations of these risks are generally limited due to diversification by investment style within each asset class, diversification by investment manager, diversification by industry sectors and issuers, and the dispersion of investments across many geographic areas. 79 Unrecognized Actuarial Gains/Losses In accordance with applicable accounting guidance, the funded status of the Company's pension plans is recorded in the consolidated balance sheets and provides for a delayed recognition of actuarial gains or losses arising from changes in the projected benefit obligation due to changes in the assumed discount rates, differences between the actual and expected value of plan assets and other assumption changes. The unrecognized pension plan actuarial gains or losses and prior service costs not yet recognized in net periodic pension cost are recognized in Accumulated Other Comprehensive Income ("AOCI"), net of tax. These gains and losses are amortized prospectively out of AOCI over a period that approximates the remaining life expectancy of participants in plans where substantially all participants are inactive, or the average remaining service period of active participants for plans with active participants. Interest and Service Cost In 2016, the Company modified the approach used to estimate the service and interest cost components of net periodic benefit cost for its significant non-U.S. plans. Historically, service and interest costs were estimated using a single weighted average discount rate derived from the yield curves used to measure the benefit obligations at the beginning of the period. This change in approach was made to improve the correlation between the projected benefit cash flows and the corresponding yield curve spot rates and to provide a more precise measurement of service and interest costs. The change does not impact the measurement of the plans’ total Projected Benefit Obligation. The Company has accounted for this change as a change in estimate, that was applied prospectively beginning in 2016. 80 U.S. Plans The following schedules provide information concerning the Company’s U.S. defined benefit pension plans and postretirement benefit plans: U.S. Pension Benefits U.S. Postretirement Benefits 2017 2016 2017 2016 (In millions of dollars) Change in benefit obligation: Benefit obligation at beginning of year Service cost Interest cost Employee contributions Effect of curtailment Actuarial loss (gain) Benefits paid Benefit obligation, December 31 Change in plan assets: Fair value of plan assets at beginning of year Actual return on plan assets Employer contributions Employee contributions Benefits paid Other Fair value of plan assets, December 31 Net funded status, December 31 Amounts recognized in the consolidated balance sheets: Current liabilities Non-current liabilities Net liability recognized, December 31 Amounts recognized in other comprehensive income (loss): Prior service (cost) credit Net actuarial (loss) gain Total recognized accumulated other comprehensive (loss) income, December 31 $ $ $ $ $ $ $ $ 5,894 $ — 264 — — 538 (475) 6,221 $ 4,365 $ 812 85 — (475) — 4,787 $ (1,434) $ 5,685 $ 106 264 — (98) 160 (223) 5,894 $ 4,160 $ 401 27 — (223) — 4,365 $ (1,529) $ (27) $ (27) $ (1,407) (1,434) $ (1,502) (1,529) $ 37 $ — 2 3 — 3 (9) 36 $ 2 $ — 6 3 (9) — 2 $ (34) $ (2) $ (32) (34) $ — $ — $ (1,766) (1,720) — $ 6 $ (1,766) $ (1,720) $ 6 $ Cumulative employer contributions in excess of (less than) net periodic cost Net amount recognized in consolidated balance sheet $ $ Accumulated benefit obligation at December 31 332 (1,434) $ 6,221 $ 191 (1,529) $ 5,894 $ (40) (34) $ — $ 40 — 2 3 — — (8) 37 3 — 5 3 (8) (1) 2 (35) (2) (33) (35) (3) 11 8 (43) (35) — (In millions of dollars) Reconciliation of prior service credit (cost) recognized in accumulated other comprehensive income (loss): Beginning balance Recognized as component of net periodic benefit cost Prior service cost, December 31 U.S. Pension Benefits U.S. Postretirement Benefits 2017 2016 2017 2016 $ $ — $ — — $ — $ — — $ (3) $ 3 — $ (7) 4 (3) 81 (In millions of dollars) Reconciliation of net actuarial (loss) gain recognized in accumulated other comprehensive income (loss): Beginning balance Recognized as component of net periodic benefit cost (credit) Changes in plan assets and benefit obligations recognized in other comprehensive income (loss): Effect of curtailment Other Liability experience Asset experience U.S. Pension Benefits U.S. Postretirement Benefits 2017 2016 2017 2016 $ (1,720) $ (1,754) $ 11 $ 37 74 — — (538) 455 98 — (160) 22 (1) — (1) (3) — (4) 13 (2) — — — — — 11 Total (loss) gain recognized as change in plan assets and benefit obligations (83) (40) Net actuarial (loss) gain, December 31 $ (1,766) $ (1,720) $ 6 $ For the Years Ended December 31, (In millions of dollars) Total recognized in net periodic benefit cost and other comprehensive (income) loss U.S. Pension Benefits 2016 2017 2015 U.S. Postretirement Benefits 2016 2017 2015 $ (10) $ 31 $ 146 $ 5 $ 2 $ (138) Estimated amounts that will be amortized from accumulated other comprehensive loss to net periodic pension cost in the next fiscal year: (In millions of dollars) Net actuarial loss U.S. Pension Benefits U.S. Postretirement Benefits $ 2018 54 $ 2018 1 The weighted average actuarial assumptions utilized in determining the above amounts for the U.S. defined benefit and other U.S. postretirement plans as of the end of the year are as follows: Weighted average assumptions: Discount rate (for expense) Expected return on plan assets Rate of compensation increase (for expense) Discount rate (for benefit obligation) U.S. Pension Benefits U.S. Postretirement Benefits 2017 2016 2017 2016 4.58% 7.95% — 3.86% 4.71% 8.72% 2.00% 4.58% 4.12% — — 3.67% 4.36% — — 4.12% In recent years, the Society of Actuaries in the United States has issued new mortality tables and mortality improvement scales. The Company considered the effect of these tables and scales, along with other available information on mortality improvement and industry specific mortality studies, to select its assumptions for measurement of the plans’ benefit obligations at December 31, 2017 and 2016. The projected benefit obligation, accumulated benefit obligation and aggregate fair value of plan assets for U.S. pension plans with accumulated benefit obligations in excess of plan assets were $6.2 billion, $6.2 billion and $4.8 billion, respectively, as of December 31, 2017 and $5.9 billion, $5.9 billion and $4.4 billion, respectively, as of December 31, 2016. 82 The projected benefit obligation and fair value of plan assets for U.S. pension plans with projected benefit obligations in excess of plan assets was $6.2 billion and $4.8 billion, respectively, as of December 31, 2017 and $5.9 billion and $4.4 billion, respectively, as of December 31, 2016. As of December 31, 2017, the U.S. qualified plan holds 4 million shares of the Company’s common stock which were contributed to the qualified plan by the Company in 2005. This represented approximately 6.8% of that plan's assets as of December 31, 2017. In addition, plan assets may be invested in funds managed by Mercer Investments, a subsidiary of the Company. The components of the net periodic benefit cost (credit) for the U.S. defined benefit and other postretirement benefit plans are as follows: U.S. Plans only For the Years Ended December 31, (In millions of dollars) Service cost Interest cost Expected return on plan assets Amortization of prior service (credit) cost Recognized actuarial loss (gain) Net periodic benefit (credit) cost Plan termination Total (credit) cost Pension Benefits 2016 2017 2015 Postretirement Benefits 2016 2017 $ — $ 264 (357) — 37 (56) $ — (56) $ $ $ 106 $ 264 (379) — 74 65 $ — 65 $ 114 $ — $ 254 (373) — 146 141 $ — 141 $ 2 — 3 (1) 4 $ — 4 $ 2015 1 — $ 2 2 — — 3 4 (2) (2) 4 4 $ — (128) 4 $ (124) Effective September 1, 2015, the Company divided its U.S. qualified defined benefit plan to provide enhanced flexibility to manage the risk associated with those participants not receiving benefit accruals. The existing plan was amended to cover only the retirees then receiving benefits and terminated vested participants as of August 1, 2015. The Company's active participants as of that date were transferred into a newly established, legally separate qualified defined benefit plan. The benefits offered to the plans' participants were unchanged. As a result of the plan amendment and establishment of the new plan, the Company re-measured the assets and liabilities of the two plans as required under U.S. GAAP, based on assumptions and market conditions at the amendment date. The net periodic pension expense recognized in 2015 reflects the weighted average costs of the December 31, 2014 measurement and the September 1, 2015 re-measurement. In October 2016, the Company modified its U.S. defined benefit pension plans to discontinue further benefit accruals for participants after December 31, 2016. At the same time, the Company amended its U.S. defined contribution retirement plans for most of its U.S. employees to add an automatic Company contribution equal to 4% of eligible base pay beginning on January 1, 2017. This new Company contribution, together with the Company’s matching contribution, provides eligible U.S. employees with the opportunity to receive a total contribution of up to 7% of eligible base pay. As required under GAAP, the defined benefit plans that were significantly impacted by the modification were re-measured in October 2016 using market data and assumptions as of the modification date. The net periodic pension expense recognized in 2016 reflects the weighted average costs of the December 31, 2015 measurement and the October 2016 re-measurement. In addition, the U.S. qualified plans were merged effective December 30, 2016, since no participants would be receiving benefit accruals after December 31, 2016. In March 2015, the Company amended its U.S. Post-65 retiree medical reimbursement plan (the "RRA plan"), resulting in its termination, with benefits to certain participants paid through December 31, 2016. As a result of the termination of the RRA plan, the Company recognized a net credit of approximately $125 million in the first quarter of 2015. The assumed health care cost trend rate for Medicare eligibles and non-Medicare eligibles is approximately 6.38% in 2017, gradually declining to 4.5% in 2039. Assumed health care cost trend rates have a small effect on the amounts reported for the U.S. health care plans because the Company caps its share of health care trend at 5%. A one percentage point change in assumed health care cost trend rates would have no effect on the total service and interest cost components or the postretirement benefit 83 obligation. Estimated Future Contributions The Company expects to contribute approximately $27 million to its U.S. plans in 2018. The Company’s policy for funding its tax-qualified defined benefit retirement plans is to contribute amounts at least sufficient to meet the funding requirements set forth in the U.S. and applicable foreign law. 84 Non-U.S. Plans The following schedules provide information concerning the Company’s non-U.S. defined benefit pension plans and non-U.S. postretirement benefit plans: (In millions of

billion and $0.9 billion, respectively, as of December 31, 2016. The projected benefit obligation and fair value of plan assets for non-U.S. pension plans with projected benefit obligations in excess of plan assets was $2.2 billion and $1.9 billion, respectively, as of December 31, 2017 and $2.1 billion and $1.7 billion, respectively, as of December 31, 2016. Non-U.S. Plan Amendments In March 2017, the Company modified its defined benefit pension plans in Canada to discontinue further benefit accruals for participants after December 31, 2017 and replaced them with a defined contribution arrangement. The Company also amended its post-retirement benefits plan in Canada so that individuals who retire after April 1, 2019 will not be eligible to participate, except in certain situations. The Company re-measured the assets and liabilities of the plans, based on assumptions and market conditions on the amendment date. Effective August 1, 2015, the Company amended its Ireland defined benefit pension plans to close those plans to future benefit accruals and replaced those plans with a defined contribution arrangement. The Company re-measured the assets and liabilities of the plans, based on assumptions and market conditions on the amendment date. The net periodic pension costs recognized in 2015 reflect the weighted average costs of the December 31, 2014 measurement and the August 1, 2015 re- measurement. After completion of a consultation period with affected colleagues, in January 2015, the Company amended its U.K. defined benefit pension plans to close those plans to future benefit accruals effective August 1, 2015 and replaced those plans, along with its existing defined contribution plans, with a new, comprehensive defined contribution arrangement. This change resulted in a curtailment of the U.K. defined benefit plans and, as required under GAAP, the Company re-measured the defined benefit plans’ assets and liabilities at the amendment date, based on assumptions and market conditions at that date. The net periodic benefit costs recognized in 2015 are the weighted average resulting from the December 31, 2014 measurement and the January 2015 re-measurement. 87 Components of Net Periodic Benefits Costs The components of the net periodic benefit cost for the non-U.S. defined benefit and other postretirement benefit plans and the curtailment, settlement and termination expenses are as follows: For the Years Ended December 31, (In millions of dollars) Service cost Interest cost Expected return on plan assets Amortization of prior service credit Recognized actuarial loss Net periodic benefit (credit) cost Settlement loss Curtailment (gain) loss Total (credit) cost Non-U.S. Pension Benefits Non-U.S. Postretirement Benefits 2017 2016 2015 2017 2016 2015 $ 76 $ 72 $ 82 $ 1 $ 2 $ 233 (564) (2) 130 (127) 54 (1) 273 (561) (1) 94 (123) — (4) 333 (604) (1) 125 (65) 1 5 2 — (2) 1 2 — — 3 — — — 5 — — $ (74) $ (127) $ (59) $ 2 $ 5 $ 2 3 — — 1 6 — — 6 The non-U.S. pension credit in 2017 includes the impact of the pension settlement charge in the U.K., as previously discussed. The assumed health care cost trend rate was approximately 5.12% in 2017, gradually declining to 4.41% in 2027. Assumed health care cost trend rates can have a significant effect on the amounts reported for the non-U.S. health care plans. A one percentage point change in assumed health care cost trend rates would have the following effects: (In millions of dollars) Effect on total of service and interest cost components Effect on postretirement benefit obligation Estimated Future Contributions 1 Percentage Point Increase $ $ — $ $ 7 1 Percentage Point Decrease — (6) The Company expects to contribute approximately $82 million to its non-U.S. pension plans in 2018. Funding requirements for non-U.S. plans vary by country. Contribution rates are generally based on local funding practices and requirements, which may differ significantly from measurements under U.S. GAAP. Funding amounts may be influenced by future asset performance, the level of discount rates and other variables impacting the assets and/or liabilities of the plan. Discretionary contributions may also be affected by alternative uses of the Company’s cash flows, including dividends, investments and share repurchases. In the U.K., the assumptions used to determine pension contributions are the result of legally-prescribed negotiations between the Company and the plans' trustee that typically occurs every three years in conjunction with the actuarial valuation of the plans. Currently, this results in a lower funded status than under U.S. GAAP and may result in contributions irrespective of the U.S. GAAP funded status. In November 2016, the Company and the Trustee of the U.K. Defined Benefits Plans agreed to a funding deficit recovery plan for the U.K. defined benefit pension plans. The current agreement with the Trustee sets out the annual deficit contributions which would be due based on the deficit at December 31, 2015. The funding level is subject to re-assessment, in most cases on November 1 of each year. If the funding level on November 1 is sufficient, no deficit funding contributions will be required in the following year, and the contribution amount will be deferred. The funding level was re-assessed on November 1, 2017 and no deficit funding contributions are required in 2018. The funding level will be re-assessed on November 1, 2018. As part of a long-term strategy, which depends on having greater influence over asset allocation and overall investment decisions, in November 2016 the Company renewed its agreement to support annual deficit contributions by the U.K. operating companies under certain circumstances, up to GBP 450 million over a seven-year period. 88 Estimated Future Benefit Payments The estimated future benefit payments for the Company's pension and postretirement benefit plans are as follows: For the Years Ended December 31, (In millions of dollars) 2018 2019 2020 2021 2022 2023-2027 Pension Benefits Postretirement Benefits U.S. 254 268 285 294 303 1,642 $ $ $ $ $ $ Non-U.S. 279 $ 297 $ 305 $ 316 $ 326 $ 1,837 $ $ $ $ $ $ $ U.S. Non-U.S. 3 $ 4 $ 4 $ 3 $ 3 $ 17 $ 4 4 4 4 3 14 Defined Benefit Plans Fair Value Disclosures The U.S. and non-U.S. plan investments are classified into Level 1, which refers to investments valued using quoted prices from active markets for identical assets; Level 2, which refers to investments not traded on an active market but for which observable market inputs are readily available; Level 3, which refers to investments valued based on significant unobservable inputs; and NAV, which refers to investments valued using net asset value as a practical expedient. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. 89 The following table sets forth, by level within the fair value hierarchy, a summary of the U.S. and non-U.S. plans' investments measured at fair value on a recurring basis at December 31, 2017 and 2016: Fair Value Measurements at December 31, 2017 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) $ Assets (In millions of dollars) Common/collective trusts Corporate obligations Corporate stocks Private equity/partnerships Government securities Real estate Short-term investment funds Company common stock Other investments Total investments $ 375 $ — 1,467 — 15 — 391 326 12 2,586 $ — $ 3,620 34 — 556 — 16 — 12 4,238 $ — $ 20 2 — — — — — 350 372 $ NAV Total 7,611 $ — — 803 — 566 — — — 8,980 $ 7,986 3,640 1,503 803 571 566 407 326 374 16,176 Fair Value Measurements at December 31, 2016 Assets (In millions of dollars) Common/collective trusts Corporate obligations Corporate stocks Private equity/partnerships Government securities Real estate Short-term investment funds Company common stock Other investments Total investments Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) $ $ 16 $ — 2,009 — 11 — 297 270 15 2,618 $ — $ 3,024 3 — 380 — 22 — 23 3,452 $ — $ 9 2 — — — — — 312 323 $ NAV Total 6,805 $ — — 722 — 412 — — — 7,939 $ 6,821 3,033 2,014 722 391 412 319 270 350 14,332 90 The tables below set forth a summary of changes in the fair value of the plans’ Level 3 assets for the years ended December 31, 2017 and December 31, 2016: Assets (In millions) Other investments Corporate stocks Corporate obligations Total assets Assets (In millions) Other investments Corporate stocks Corporate obligations Fair Value, January 1, 2017 Purchases Sales Unrealized Gain/ (Loss) Realized Gain/ (Loss) Exchange Rate Impact Transfers in/(out) and Other Fair Value, December 31, 2017 $ 312 $ 2 9 20 — 9 — (1) $ (15) $ (7) $ — $ — 9 2 — — 40 — 1 $ — $ — (7) 350 2 20 372 $ 323 $ 29 $ (16) $ $ — $ 41 $ (7) $ Fair Value, January 1, 2016 Purchases Sales Unrealized Gain/ (Loss) Realized Gain/ (Loss) Exchange Rate Impact Transfers in/(out) and Other Fair Value, December 31, 2016 $ 257 $ 2 1 27 — 8 $ (28) $ — — $ 67 — 1 1 — — 1 $ (12) $ — $ 312 — (1) — — 2 9 $ (13) $ — $ 323 Total assets $ 260 $ 35 $ (28) $ 68 $ The following is a description of the valuation methodologies used for assets measured at fair value: Company common stock: Valued at the closing price reported on the New York Stock Exchange. Common stocks, preferred stocks, convertible equity securities, rights/warrants and real estate investment trusts (included in Corporate stocks): Valued at the closing price reported on the primary exchange. Corporate bonds (included in Corporate obligations): The fair value of corporate bonds is estimated using recently executed transactions, market price quotations (where observable) and bond spreads. The spread data used are for the same maturity as the bond. If the spread data does not reference the issuer, then data that references a comparable issuer are used. When observable price quotations are not available, fair value is determined based on cash flow models. Commercial mortgage-backed and asset-backed securities (included in Corporate obligations): Fair value is determined using discounted cash flow models. Observable inputs are based on trade and quote activity of bonds with similar features including issuer vintage, purpose of underlying loan (first or second lien), prepayment speeds and credit ratings. The discount rate is the combination of the appropriate rate from the benchmark yield curve and the discount margin based on quoted prices. Common/Collective trusts: Valued at the net asset value of units of a bank collective trust. The net asset value as provided by the trustee, is used as a practical expedient to estimate fair value. The net asset value is based on the fair value of the underlying investments held by the fund less its liabilities. This practical expedient is not used when it is determined to be probable that the fund will sell the investment for an amount different than the reported net asset value. U.S. government bonds (included in Government securities): The fair value of U.S. government bonds is estimated by pricing models that utilize observable market data including quotes, spreads and data points for yield curves. U.S. agency securities (included in Government securities): U.S. agency securities are comprised of two main categories consisting of agency issued debt and mortgage pass-throughs. Agency issued debt securities are valued by benchmarking market-derived prices to quoted market prices and trade data for identical or comparable securities. Mortgage pass-throughs include certain "To-be-announced" (TBA) securities and mortgage pass-through pools. TBA securities are generally valued using quoted market prices or are benchmarked thereto. Fair value of mortgage pass-through pools are model driven with respect to spreads of the comparable TBA security. 91 Private equity and real estate partnerships: Investments in private equity and real estate partnerships are valued based on the fair value reported by the manager of the corresponding partnership and reported on a one quarter lag. The managers provide unaudited quarterly financial statements and audited annual financial statements which set forth the value of the fund. The valuations obtained from the managers are based on various analyses on the underlying holdings in each partnership, including financial valuation models and projections, comparable valuations from the public markets, and precedent private market transactions. Investments are valued in the accompanying financial statements based on the Plan’s beneficial interest in the underlying net assets of the partnership as determined by the partnership agreement. Insurance group annuity contracts: The fair values for these investments are based on the current market value of the aggregate accumulated contributions plus interest earned. Swap assets (included in Other investments): Fair values for interest rate swaps, equity index swaps and inflation swaps are estimated using a discounted cash flow pricing model. These models use observable market data such as contractual fixed rate, spot equity price or index value and dividend data. The fair values of credit default swaps are estimated using an income approach model which determines expected cash flows based on default probabilities from the issuer-specific credit spread curve and credit loss recovery rates, both of which are dependent on market quotes. Short-term investment funds: Primarily high-grade money market instruments valued at net asset value at year-end. Registered investment companies: Valued at the closing price reported on the primary exchange. Defined Contribution Plans The Company maintains certain defined contribution plans for its employees, including the Marsh & McLennan Companies 401(k) Savings & Investment Plan ("401(k) Plan"), that are qualified under U.S. tax laws. Under these plans, eligible employees may contribute a percentage of their base salary, subject to certain limitations. For the 401(k) Plan, the Company matches a fixed portion of the employees’ contributions. In addition, as mentioned above, as part of the modification to its U.S. defined benefit pension plans, the Company also amended its U.S. defined contribution retirement plans for most of its U.S. employees to add an automatic Company contribution equal to 4% of eligible base pay beginning on January 1, 2017. The 401(k) Plan contains an Employee Stock Ownership Plan feature under U.S. tax law. Approximately $499 million of the 401(k) Plan’s assets at December 31, 2017 and $436 million at December 31, 2016 were invested in the Company’s common stock. If a participant does not choose an investment direction for his or her future contributions, they are automatically invested in a BlackRock LifePath Portfolio that most closely matches the participant’s expected retirement year. The cost of these defined contribution plans was $130 million in 2017, $53 million in 2016 and $51 million in 2015. The increase in cost in 2017 as compared to 2016 is primarily due to the additional automatic Company contribution mentioned above. In addition, the Company has a significant defined contribution plan in the U.K. As noted above, effective August 1, 2014, a newly formed defined contribution plan replaced the existing defined contribution and defined benefit plans with regard to future service. The cost of the U.K. defined contribution plan was $75 million, $81 million and $93 million in 2017, 2016 and 2015, respectively. The decrease in cost over the past three years is primarily due to the impact of foreign currency translation. 8. Stock Benefit Plans The Company maintains multiple stock-based payment arrangements under which employees are awarded grants of restricted stock units, stock options and other forms of stock-based benefits. Marsh & McLennan Companies, Inc. Incentive and Stock Award Plans On May 19, 2011, the Marsh & McLennan Companies, Inc. 2011 Incentive and Stock Award Plan (the "2011 Plan") was approved by the Company's stockholders. The 2011 Plan replaced the Company's two previous equity incentive plans (the 2000 Senior Executive Incentive and Stock Award Plan and the 2000 Employee Incentive and Stock Award Plan). 92 The types of awards permitted under the 2011 Plan include stock options, restricted stock and restricted stock units payable in Company common stock or cash, and other stock-based and performance-based awards. The Compensation Committee of the Board of Directors (the "Compensation Committee") determines, at its discretion, which affiliates may participate in the 2011 Plan, which eligible employees will receive awards, the types of awards to be received, and the terms and conditions thereof. The right of an employee to receive an award may be subject to performance conditions as specified by the Compensation Committee. The 2011 Plan contains a provision which, in the event of a change in control of the Company, may accelerate the vesting of the awards. This provision requires both a change in control of the Company and a subsequent specified termination of employment for vesting to be accelerated. The 2011 Plan retains the remaining share authority of the two previous plans as of the date the 2011 Plan was approved by stockholders. Thus, approximately 23.2 million shares of common stock, plus shares remaining unused under the previous plans, are available for awards over the life of the 2011 Plan. The current practice is to grant non-qualified stock options, restricted stock units and/or performance stock units ("PSUs") on an annual basis to senior executives and a limited number of other employees as part of their total compensation. Restricted stock units are also granted to new hires or as retention awards for certain employees. Restricted stock has not been granted since 2005. Stock Options: Options granted under the 2011 Plan may be designated as either incentive stock options or non-qualified stock options. The Compensation Committee determines the terms and conditions of the option, including the time or times at which an option may be exercised, the methods by which such exercise price may be paid, and the form of such payment. Options are generally granted with an exercise price equal to the market value of the Company's common stock on the date of grant. These option awards generally vest 25% per annum and have a contractual term of 10 years. The estimated fair value of options granted is calculated using the Black-Scholes option pricing valuation model. This model takes into account several factors and assumptions. The risk-free interest rate is based on the yield on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumption at the time of grant. The expected life (estimated period of time outstanding) is estimated using the contractual term of the option and the effects of employees' expected exercise and post-vesting employment termination behavior. The Company uses a blended volatility rate based on the following: (i) volatility derived from daily closing price observations for the 10-year period ended on the valuation date, (ii) implied volatility derived from traded options for the period one week before the valuation date and (iii) average volatility for the 10-year periods ended on 15 anniversaries prior to the valuation date, using daily closing price observations. The expected dividend yield is based on expected dividends for the expected term of the stock options. The assumptions used in the Black-Scholes option pricing valuation model for options granted by the Company in 2017, 2016 and 2015 are as follows: Risk-free interest rate Expected life (in years) Expected volatility Expected dividend yield 2017 2.09% 6.0 23.23% 1.86% 2016 1.39% 6.0 25.55% 2.15% 2015 1.78% 6.0 23.75% 1.97% 93 A summary of the status of the Company’s stock option awards as of December 31, 2017 and changes during the year then ended is presented below: Balance at January 1, 2017 Granted Exercised Forfeited Balance at December 31, 2017 Options vested or expected to vest at December 31, 2017 Options exercisable at December 31, 2017 Weighted Average Exercise Price Shares 13,242,529 $ 1,710,853 $ (4,258,027) $ (494,653) $ 10,200,702 $ 39.15 73.20 30.42 62.00 47.39 Weighted Average Remaining Contractual Term Aggregate Intrinsic Value ($000) 5.9 years $ 351,317 10,052,720 $ 47.17 5.9 years $ 348,494 6,247,224 $ 37.75 4.6 years $ 275,398 In the above table, forfeited options are unvested options whose requisite service period has not been met. Expired options are vested options that were not exercised. The weighted-average grant-date fair value of the Company's option awards granted during the years ended December 31, 2017, 2016 and 2015 was $15.01, $11.57 and $11.34, respectively. The total intrinsic value of options exercised during the same periods was $195.3 million, $137.7 million and $124.6 million, respectively. As of December 31, 2017, there was $14.9 million of unrecognized compensation cost related to the Company's option awards. The weighted-average period over which that cost is expected to be recognized is approximately 1.36 years. Cash received from the exercise of stock options for the years ended December 31, 2017, 2016 and 2015 was $126.7 million, $105.4 million and $134.7 million, respectively. The Company's policy is to issue treasury shares upon option exercises or share unit conversion. The Company intends to issue treasury shares as long as an adequate number of those shares is available. Restricted Stock Units and Performance Stock Units: Restricted stock units may be awarded under the Company's 2011 Incentive and Stock Award Plan. The Compensation Committee determines the restrictions on such units, when the restrictions lapse, when the units vest and are paid, and under what terms the units are forfeited. The cost of these awards is amortized over the vesting period, which is generally three years. Awards to senior executives and other employees may include three-year performance-based restricted stock units and three-year service-based restricted stock units. The payout of performance stock units (payable in shares of the Company's common stock) ranges, generally, from 0-200% of the number of units granted, based on the achievement of objective, pre-determined Company performance measure(s), generally, over a three-year performance period. The Company accounts for these awards as performance condition restricted stock units. The performance condition is not considered in the determination of grant date fair value of such awards. Compensation cost is recognized over the performance period based on management's estimate of the number of units expected to vest and shares to be paid and is adjusted to reflect the actual number of shares paid out at the end of the three-year performance period. Dividend equivalents are not paid out unless and until such time that the award vests. 94 A summary of the status of the Company's restricted stock units and performance stock units as of December 31, 2017 and changes during the period then ended is presented below: Non-vested balance at January 1, 2017 Granted Vested Forfeited Non-vested balance at December 31, 2017 Restricted Stock Units Weighted Average Grant Date Fair Value 56.40 73.23 55.31 65.06 66.97 Shares 3,044,029 $ 2,610,599 $ (1,307,825) $ (294,056) $ 4,052,747 $ Performance Stock Units Weighted Average Grant Date Fair Value 54.68 73.20 48.19 61.92 62.82 Shares 722,017 $ 260,387 $ (212,458) $ (79,345) $ 690,601 $ The weighted-average grant-date fair value of the Company's restricted stock units granted during the years ended December 31, 2016 and 2015 was $57.54 and $56.81, respectively. The weighted average grant date fair value of the Company's performance stock units granted during the years ended December 31, 2016 and 2015 was $57.47 and $57.33, respectively. The total fair value of the shares distributed during the years ended December 31, 2017, 2016 and 2015 in connection with the Company's non-option equity awards was $117.1 million, $91.4 million and $114.3 million, respectively. The payout of shares in 2017 with respect to the PSUs awarded in 2014 was 120% of target based on performance for the three-year performance period. The payout of shares with respect to the PSUs that vested in 2017 due to certain types of termination was based on performance for the abbreviated performance period. In aggregate, 254,455 shares became distributable in respect to PSUs vested in 2017. As of December 31, 2017, there was $197.4 million of unrecognized compensation cost related to the Company's restricted stock units and performance stock unit awards. The weighted-average period over which that cost is expected to be recognized is approximately 1.08 years. Marsh & McLennan Companies Stock Purchase Plans In May 1999, the Company's stockholders approved an employee stock purchase plan (the "1999 Plan") to replace the 1994 Employee Stock Purchase Plan (the "1994 Plan"), which terminated on September 30, 1999 following its fifth annual offering. Under the current terms of the Plan, shares are purchased four times during the plan year at a price that is 95% of the average market price on each quarterly purchase date. Under the 1999 Plan, after including the available remaining unused shares in the 1994 Plan and reducing the shares available by 10,000,000 consistent with the Company's Board of Directors' action in March 2007, no more than 35,600,000 shares of the Company's common stock may be sold. Employees purchased 428,244 shares during the year ended December 31, 2017 and at December 31, 2017, 1,353,166 shares were available for issuance under the 1999 Plan. Under the 1995 Company Stock Purchase Plan for International Employees (the "International Plan"), after reflecting the additional 5,000,000 shares of common stock for issuance approved by the Company's Board of Directors in July 2002, and the addition of 4,000,000 shares due to a shareholder action in May 2007, no more than 12,000,000 shares of the Company's common stock may be sold. Employees purchased 121,292 shares during the year ended December 31, 2017 and there were 2,491,910 shares available for issuance at December 31, 2017 under the International Plan. The plans are considered non-compensatory. 95 9. Fair Value Measurements Fair Value Hierarchy The Company has categorized its assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy as defined by the FASB. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy, for disclosure purposes, is determined based on the lowest level input that is significant to the fair value measurement. Assets and liabilities recorded in the consolidated balance sheets at fair value are categorized based on the inputs in the valuation techniques as follows: Level 1. Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market (examples include active exchange-traded equity securities and exchange-traded money market mutual funds). Assets and liabilities using Level 1 inputs include exchange-traded equity securities, exchange-traded mutual funds and money market funds. Level 2. Assets and liabilities whose values are based on the following: a) b) c) d) Quoted prices for similar assets or liabilities in active markets; Quoted prices for identical or similar assets or liabilities in non-active markets (examples include corporate and municipal bonds, which trade infrequently); Pricing models whose inputs are observable for substantially the full term of the asset or liability (examples include most over-the-counter derivatives, including interest rate and currency swaps); and Pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full asset or liability (for example, certain mortgage loans). The Company does not have any assets or liabilities that use Level 2 inputs. Level 3. Assets and liabilities whose values are based on prices, or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability (certain commercial mortgage whole loans, and long-dated or complex derivatives including certain foreign exchange options and long-dated options on gas and power). Liabilities using Level 3 inputs include liabilities for contingent purchase consideration. Valuation Techniques Equity Securities, Money Market Funds and Mutual Funds - Level 1 Investments for which market quotations are readily available are valued at the sale price on their principal exchange or, for certain markets, official closing bid price. Money market funds are valued using a valuation technique that results in price per share at $1.00. Contingent Purchase Consideration Liability - Level 3 Purchase consideration for some acquisitions made by the Company includes contingent consideration arrangements. These arrangements typically provide for the payment of additional consideration if earnings and revenue targets are met over periods from two to four years. The fair value of contingent consideration is estimated as the present value of future cash flows resulting from the projected revenue and earnings of the acquired entities. 96 The following fair value hierarchy table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2017 and 2016: (In millions of dollars) Identical Assets (Level 1) Observable Inputs (Level 2) Unobservable Inputs (Level 3) Total 12/31/17 12/31/16 12/31/17 12/31/16 12/31/17 12/31/16 12/31/17 12/31/16 Assets: Financial instruments owned: Exchange traded equity securities (a) Mutual funds(a) Money market funds(b) Total assets measured at fair value Fiduciary Assets: Money market funds Total fiduciary assets measured at fair value Liabilities: Contingent purchase consideration liability(c) Total liabilities measured at fair value $ 81 $ 89 $ — $ — $ — $ — $ 81 $ 158 143 141 22 — — — — — — — — 158 143 89 141 22 $ $ $ $ $ 382 $ 252 $ — $ — $ — $ — $ 382 $ 252 111 111 $ $ 90 90 $ $ — $ — $ — $ — $ 111 — $ — $ — $ — $ 111 — $ — $ — $ — $ 189 — $ — $ — $ — $ 189 $ $ 241 241 $ $ 189 189 $ $ $ $ 90 90 241 241 (a) Included in other assets in the consolidated balance sheets. (b) Included in cash and cash equivalents in the consolidated balance sheets. (c) Included in accounts payable and accrued liabilities and other liabilities in the consolidated balance sheets. During the year ended December 31, 2017, there were no assets or liabilities that were transferred between any of the levels. The table below sets forth a summary of the changes in fair value of the Company’s Level 3 liabilities for the years ended December 31, 2017 and December 31, 2016 that represent contingent purchase consideration related to acquisitions: (In millions) Balance at January 1, Additions Payments Revaluation Impact Other (a) Balance at December 31, 2017 2016 $ 241 $ 51 (108) 3 2 309 17 (86) 9 (8) $ 189 $ 241 (a) Primarily reflects the impact of foreign exchange. The fair value of the contingent purchase consideration liability is based on projections of revenue and earnings for the acquired entities that are reassessed on a quarterly basis. As set forth in the table above, based on the Company's ongoing assessment of the fair value of contingent consideration, the Company recorded a net increase in the estimated fair value of such liabilities for prior period acquisitions of $3 million for the year ended December 31, 2017. A 5% increase in the above mentioned projections would increase the liability by approximately $18 million. A 5% decrease in the above mentioned projections would decrease the liability by approximately $19 million. Long-Term Investments The Company holds investments in certain private equity investments, public companies and private companies that are accounted for using the equity method of accounting. The carrying value of these investments was $405 million and $389 million at December 31, 2017 and 2016, respectively. 97 Private Equity Investments The Company's investments in private equity funds were $76 million and $79 million at December 31, 2017 and December 31, 2016, respectively. The carrying values of these private equity investments approximates fair value. The underlying private equity funds follow investment company accounting, where investments within the fund are carried at fair value. The Company records in earnings, investment gains/losses for its proportionate share of the change in fair value of the funds. These investments are included in other assets in the consolidated balance sheets. Investments in Public and Private Companies Alexander Forbes: The Company owns approximately 33% of the common stock of Alexander Forbes, a South African company listed on the Johannesburg Stock Exchange, which it purchased in 2014 for 7.50 South African Rand per share. As of December 31, 2017, the carrying value of the Company’s investment in Alexander Forbes was approximately $266 million. As of December 31, 2017, the market value of the approximately 443 million shares of Alexander Forbes owned by the Company, based on the December 31, 2017 closing share price of 6.87 South African Rand per share, was approximately $239 million. The Company considered several factors in assessing its investment in Alexander Forbes, including its financial position, the near- and long-term prospects of Alexander Forbes and the broader South African economy and capital markets, the length of time and extent to which the market value was below cost and the Company’s intent and ability to retain the investment for a sufficient period of time to allow for anticipated recovery in market value. The shares traded over a broad range during the year, with a high of 7.95 Rand and a low of 5.26 Rand, and experienced several cycles of price declines and recovery in 2017. The shares traded above 7.50 Rand multiple times during the fourth quarter of 2017. Based on its assessment of the factors discussed above, the Company determined the investment was not impaired. The Company’s investment in Alexander Forbes and its other equity investments in private insurance and consulting companies are accounted for using the equity method of accounting, the results of which are included in revenue in the consolidated income statements and the carrying value of which is included in other assets in the consolidated balance sheets. The Company records its share of income or loss on its equity method investments on a one quarter lag basis. Benefitfocus: On February 24, 2015, Mercer purchased shares of common stock of Benefitfocus (NASDAQ:BNFT) constituting approximately 9.9% of BNFT's outstanding capital stock as of the acquisition date. The purchase price for the BNFT shares and certain other rights and other consideration was approximately $75 million. Until December 31, 2016, the Company accounted for this investment under the cost method of accounting as the shares purchased were categorized as restricted. Effective December 31, 2016, these shares were no longer considered restricted for the purpose of determining if they are marketable securities under applicable accounting guidance, and are now accounted for as available for sale securities and included in other assets in the consolidated balance sheets. The value of the BNFT shares based on the closing price on the NASDAQ at December 31, 2017 was approximately $76 million. Deconsolidation of a Subsidiary Marsh operates in India through Marsh India Insurance Brokers Limited (Marsh India), which is owned 26% by Marsh and 74% by local shareholders. Prior to the second quarter of 2016, under the terms of its shareholders’ agreement with the local shareholders, Marsh had a controlling financial interest in Marsh India and its results were consolidated as required under U.S. GAAP. Under the Insurance Laws (Amendment) Act 2015 of India and related regulations issued by the Indian Insurance Regulatory and Development Authority, Indian insurance companies (including insurance intermediaries and brokers like Marsh India) must now be controlled by Indian promoters or Indian investors. In the second quarter of 2016, the shareholders’ agreement among the shareholders of Marsh India was amended to comply with these new regulations, which resulted in Marsh no longer having a controlling financial interest under U.S. GAAP. In accordance with U.S. GAAP, the Company was required to deconsolidate Marsh India and recognize its interest in Marsh India at fair value, with the difference between the carrying value and fair value recognized in earnings. The Company estimated the fair value of its interest in Marsh India, primarily using a discounted cash flow approach, which considered various 98 cash flow scenarios and a discount rate appropriate for the investment. Certain provisions relating to restrictions on sales and repurchase of shares of Marsh India owned by its employees were also required to be removed by the new regulations. As a result, the deferred compensation expense related to those shares was accelerated in the second quarter of 2016. The net gain on the Company’s pre-tax income as a result of these changes was approximately $11 million, which is included in revenue for the year ended 2016. Beginning on May 1, 2016, the Company accounted for its investment in Marsh India using the equity method of accounting. The summarized financial information presented below reflects the aggregated financial information of all equity method investees as of and for the twelve months ended September 30 of each year (or portion of those twelve months the Company owned its investment), consistent with the Company’s recognition of the results of its equity method investments on a one quarter lag. The investment income information presented below reflects the net realized and unrealized gains/losses, net of expenses, related to the Company's investments in several private equity funds. Certain of the Company’s equity method investments, including Alexander Forbes, have unclassified balance sheets. Therefore, the asset and liability information presented below are not split between current and non-current. Below is a summary of the financial information for the Company's equity method investees: For the Twelve Months Ended September 30, (In millions of dollars) Revenue Net investment income (a) Net income As of September 30, (In millions of dollars) Total assets Total liabilities Non-controlling interests 2017 628 1,834 476 $ $ $ 2016 843 1,824 91 $ $ $ 2017 24,739 22,817 19 $ $ $ 2015 1,018 1,620 196 2016 22,997 21,087 12 $ $ $ $ $ $ (a) Net investment income in 2017, 2016 and 2015 includes approximately $1.5 billion, $1.9 billion and $1.5 billion, respectively, related to Alexander Forbes, substantially all of which is credited to policy holders. 99 10. Long-term Commitments The Company leases office facilities, equipment and automobiles under non-cancelable operating leases. These leases expire on varying dates, in some instances contain renewal and expansion options, do not restrict the payment of dividends or the incurrence of debt or additional lease obligations, and contain no significant purchase options. In addition to the base rental costs, occupancy lease agreements generally provide for rent escalations resulting from increased assessments for real estate taxes and other charges. Approximately 99% of the Company’s lease obligations are for the use of office space. The consolidated statements of income include net rental costs of $354 million, $367 million and $381 million for 2017, 2016 and 2015, respectively, after deducting rentals from subleases ($8 million in 2017, $9 million in 2016 and $14 million in 2015). These net rental costs exclude rental costs and sublease income for previously accrued restructuring charges related to vacated space. At December 31, 2017, the aggregate future minimum rental commitments under all non-cancelable operating lease agreements are as follows: For the Years Ended December 31, (In millions of dollars) 2018 2019 2020 2021 2022 Subsequent years Gross Rental Commitments $ $ $ $ $ $ 355 $ 316 $ 291 $ 226 $ 207 $ 773 $ Rentals from Subleases Net Rental Commitments 314 282 260 223 206 772 41 $ 34 $ 31 $ 3 $ 1 $ 1 $ The Company has entered into agreements, primarily with various service companies, to outsource certain information systems activities and responsibilities and processing activities. Under these agreements, the Company is required to pay minimum annual service charges. Additional fees may be payable depending upon the volume of transactions processed, with all future payments subject to increases for inflation. At December 31, 2017, the aggregate fixed future minimum commitments under these agreements are as follows: For the Years Ended December 31, (In millions of dollars) 2018 2019 2020 Subsequent years Future Minimum Commitments 228 $ 106 28 25 387 $ 100 11.

The Company has established a short-term debt financing program of up to $1.5 billion through the issuance of commercial paper. The proceeds from the issuance of commercial paper are used for general corporate purposes. The Company had no commercial paper outstanding at December 31, 2017. In January 2017, the Company issued $500 million of 2.75% senior notes due 2022 and $500 million of 4.35% senior notes due 2047. The Company used the net proceeds for general corporate purposes, including the repayment of a $250 million debt maturity in April 2017. In March 2016, the Company issued $350 million of 3.30% seven-year senior notes. The Company used the net proceeds for general corporate purposes. The Company and certain of its foreign subsidiaries maintain a $1.5 billion multi-currency five-year unsecured revolving credit facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. This facility expires in November 2020 and requires the Company to maintain certain coverage and leverage ratios which are tested quarterly. There were no borrowings outstanding under this facility at December 31, 2017. Additional credit facilities, guarantees and letters of credit are maintained with various banks, primarily related to operations located outside the United States, aggregating $624 million at December 31, 2017 and $376 million at December 31, 2016. There was $0 million of outstanding borrowings under these facilities at December 31, 2017 and $1.6 million of outstanding borrowings under these facilities at December 31, 2016. 101 Scheduled repayments of long-term debt in 2018 and in the four succeeding years are $262 million, $316 million, $514 million, $515 million and $515 million, respectively. Fair value of Short-term and Long-term Debt The estimated fair value of the Company’s short-term and long-term debt is provided below. Certain estimates and judgments were required to develop the fair value amounts. The fair value amounts shown below are not necessarily indicative of the amounts that the Company would realize upon disposition, nor do they indicate the Company’s intent or need to dispose of the financial instrument. (In millions of dollars) Short-term debt Long-term debt December 31, 2017 Carrying Amount Fair Value December 31, 2016 Carrying Amount Fair Value $ $ 262 $ 5,225 $ 264 5,444 $ $ 312 $ 313 4,495 $ 4,625 The fair value of the Company’s short-term debt consists primarily of commercial paper and term debt maturing within the next year and its fair value approximates its carrying value. The estimated fair value of a primary portion of the Company's long-term debt is based on discounted future cash flows using current interest rates available for debt with similar terms and remaining maturities. Short- and long-term debt would be classified as Level 2 in the fair value hierarchy. 12. Integration and Restructuring Costs In 2017, the Company implemented restructuring actions which resulted in costs totaling $40 million. Restructuring costs consist primarily for severance at Mercer, Marsh and Corporate, as well as future rent under non-cancelable leases at Corporate. These costs were incurred as follows: Risk and Insurance Services—$11 million; Consulting—$19 million; and Corporate—$10 million. Details of the restructuring liability activity from January 1, 2016 through December 31, 2017, including actions taken prior to 2017, are as follows: (In millions) Balance at 1/1/16 Expense Incurred Cash Paid Other Balance at 12/31/16 Expense Incurred Cash Paid Other Balance at 12/31/17 15 $ 40 $ (22) $ (1) $ 32 $ 31 $ (49) $ 1 $ 15 78 4 (17) (4) 61 9 (22) 2 Total $ 93 $ 44 $ (39) $ (5) $ 93 $ 40 $ (71) $ 3 $ 50 65 As of January 1, 2015, the liability balance related to restructuring activity was $92 million. In 2015, the Company accrued $28 million and had cash payments and other adjustments of $27 million related to restructuring activities that resulted in the liability balance at January 1, 2016 reported above. The expenses associated with the above initiatives are included in compensation and benefits and other operating expenses in the consolidated statements of income. The liabilities associated with these initiatives are classified on the consolidated balance sheets as accounts payable and accrued liabilities, other liabilities, or accrued compensation and employee benefits, depending on the nature of the items. 13. Common Stock During 2017, the Company repurchased 11.5 million shares of its common stock for total consideration of $900 million. In November 2016, the Board of Directors of the Company authorized the Company to repurchase up to $2.5 billion of the Company's common stock, which superseded any prior authorizations. The Company remains authorized to purchase additional shares of its common stock up to a value of approximately $1.5 billion. There is no time limit on the authorization. During 2016, the Company purchased 12.7 million shares of its common stock for total consideration of $800 million. 102 Severance $ Future rent under non- cancelable leases and other costs The Company issued approximately 5.8 million and 5.3 million shares related to stock compensation and employee stock purchase plans during the years ended December 31, 2017 and 2016, respectively. 14. Claims, Lawsuits and Other Contingencies Litigation Matters The Company and its subsidiaries are subject to a significant number of claims, lawsuits and proceedings in the ordinary course of business. Such claims and lawsuits consist principally of alleged errors and omissions in connection with the performance of professional services, including the placement of insurance, the provision of actuarial services for corporate and public sector clients, the provision of investment advice and investment management services to pension plans, the provision of advice relating to pension buy-out transactions and the provision of consulting services relating to the drafting and interpretation of trust deeds and other documentation governing pension plans. These claims may seek damages, including punitive and treble damages, in amounts that could be significant. In establishing liabilities for errors and omissions claims in accordance with FASB guidance on Contingencies - Loss Contingencies, the Company uses case level reviews by inside and outside counsel, and internal actuarial analysis by Oliver Wyman Group, a subsidiary of the Company, and other methods to estimate potential losses. A liability is established when a loss is both probable and reasonably estimable. The liability is reviewed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable. To the extent that expected losses exceed our deductible in any policy year, the Company also records an asset for the amount that we expect to recover under any available third-party insurance programs. The Company has varying levels of third-party insurance coverage, with policy limits and coverage terms varying significantly by policy year. Governmental Inquiries and Enforcement Matters Our activities are regulated under the laws of the United States and its various states, the European Union and its member states, and the other jurisdictions in which the Company operates. Risk and Insurance Services Segment In April 2017, the Financial Conduct Authority in the United Kingdom (the "FCA") commenced a civil competition investigation into the aviation insurance and reinsurance sector. In connection with that investigation, the FCA carried out an on-site inspection at the London office of Marsh Limited, our Marsh and Guy Carpenter operating subsidiary in the United Kingdom. The FCA indicated that it had reasonable grounds for suspecting that Marsh Limited and other participants in the market have been sharing competitively sensitive information within the aviation insurance and reinsurance broking sector. In October 2017, the Company received a notice that the Directorate-General for Competition of the European Commission had commenced a civil investigation of a number of insurance brokers, including Marsh, regarding "the exchange of commercially sensitive information between competitors in relation to aviation and aerospace insurance and reinsurance broking products and services in the European Economic Area ("EEA"), as well as possible coordination between competitors." In light of the action taken by the European Commission, the FCA informed Marsh Limited at the same time that it has discontinued its investigation under U.K. competition law into the aviation insurance and reinsurance sector. In July 2017, the Directorate-General for Competition of the European Commission together with the Irish Competition and Consumer Protection Commission conducted on-site inspections at the offices of Marsh and other industry participants in Dublin in connection with an investigation regarding the "possible participation in anticompetitive agreements and/or concerted practices contrary to [E.U. competition law] in the market for commercial motor insurance in the Republic of Ireland." In December 2017, we received a request from the Directorate-General for Competition of the European Commission seeking documents and information relating to its investigation. We are cooperating with these investigations and are conducting our own reviews. As these investigations are at early stages, we are unable to predict their likely timing, outcome or ultimate impact. 103 There can be no assurance that the ultimate resolution of these or any related matters will not have a material adverse effect on our consolidated results of operations, financial condition or cash flows. In November 2017, the FCA announced the terms of reference for a market study concerning the wholesale insurance broker sector in the United Kingdom, which affects Marsh and Guy Carpenter. The FCA is conducting the study to assess “how effective competition is working in the wholesale insurance broker sector” and "how brokers influence competition in the underwriting sector." The FCA is expected to publish its interim report in the fall of 2018, with a final report expected in 2019. Consulting Segment In June 2017, the FCA issued a final report in connection with a market study of the U.K. asset management industry, which includes asset managers and investment consultants, including Mercer. Following the report, in September 2017, the FCA announced its decision to refer the investment consulting and fiduciary management markets to the U.K. Competition & Markets Authority (the "CMA") for a market investigation. The CMA expects to conclude its investigation of the investment consulting and fiduciary management markets by March 2019. In the ordinary course of business, the Company is also subject to other investigations, market studies, subpoenas, lawsuits and other regulatory actions undertaken by governmental authorities. Other Contingencies-Guarantees In connection with its acquisition of U.K.-based Sedgwick Group in 1998, the Company acquired several insurance underwriting businesses that were already in run-off, including River Thames Insurance Company Limited ("River Thames"), which the Company sold in 2001. Sedgwick guaranteed payment of claims on certain policies underwritten through the Institute of London Underwriters (the "ILU") by River Thames. The policies covered by this guarantee were reinsured up to £40 million by a related party of River Thames. Payment of claims under the reinsurance agreement is collateralized by segregated assets held in a trust. As of December 31, 2017, the reinsurance coverage exceeded the best estimate of the projected liability of the policies covered by the guarantee. To the extent River Thames or the reinsurer is unable to meet its obligations under those policies, a claimant may seek to recover from the Company under the guarantee. From 1980 to 1983, the Company owned indirectly the English & American Insurance Company ("E&A"), which was a member of the ILU. The ILU required the Company to guarantee a portion of E&A's obligations. After E&A became insolvent in 1993, the ILU agreed to discharge the guarantee in exchange for the Company's agreement to post an evergreen letter of credit that is available to pay claims by policyholders on certain E&A policies issued through the ILU and incepting between July 3, 1980 and October 6, 1983. Certain claims have been paid under the letter of credit and the Company anticipates that additional claimants may seek to recover against the letter of credit. * * * * The pending proceedings described above and other matters not explicitly described in this Note 14 on Claims, Lawsuits and Other Contingencies may expose the Company or its subsidiaries to liability for significant monetary damages, fines, penalties or other forms of relief. Where a loss is both probable and reasonably estimable, the Company establishes liabilities in accordance with FASB guidance on Contingencies - Loss Contingencies. Except as described above, the Company is not able at this time to provide a reasonable estimate of the range of possible loss attributable to these matters or the impact they may have on the Company's consolidated results of operations, financial position or cash flows. This is primarily because these matters are still developing and involve complex issues subject to inherent uncertainty. Adverse determinations in one or more of these matters could have a material impact on the Company's consolidated results of operations, financial condition or cash flows in a future period. 104 15. Segment Information The Company is organized based on the types of services provided.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2018 expressed an unqualified opinion on the Company’s internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide reasonable basis for our opinion. /s/ Deloitte & Touche LLP New York, New York February 22, 2018 We have served as the Company’s auditor since 1989. 107 Marsh & McLennan Companies, Inc. and Subsidiaries SELECTED QUARTERLY FINANCIAL DATA AND SUPPLEMENTAL INFORMATION (UNAUDITED) First Quarter Second Quarter Third Quarter Fourth Quarter (In millions, except per share figures) 2017: Revenue Operating income Income from continuing operations Discontinued operations, net of tax Net income attributable to the Company Basic Per Share Data(a): Continuing operations Discontinued operations, net of tax Net income attributable to the Company Diluted Per Share Data(a): Continuing operations Discontinued operations, net of tax Net income attributable to the Company Dividends Paid Per Share 2016: Revenue Operating income Income from continuing operations Discontinued operations, net of tax Net income attributable to the Company Basic Per Share Data: Continuing operations Discontinued operations, net of tax Net income attributable to the Company Diluted Per Share Data: Continuing operations Discontinued operations, net of tax Net income attributable to the Company Dividends Paid Per Share $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ 3,503 $ 3,495 $ 3,341 $ 809 $ 578 $ — $ 569 $ 1.10 $ — $ 1.10 $ 1.09 $ — $ 1.09 $ 0.34 $ 764 $ 507 $ — $ 501 $ 0.98 $ — $ 0.98 $ 0.96 $ — $ 0.96 $ 0.34 $ 597 $ 397 $ — $ 393 $ 0.77 $ — $ 0.77 $ 0.76 $ — $ 0.76 $ 3,685 686 28 2 29 0.05 0.01 0.06 0.05 0.01 0.06 0.375 $ 0.375 3,336 $ 3,376 $ 3,135 $ 3,364 733 $ 490 $ — $ 481 $ 0.92 $ — $ 0.92 $ 0.91 $ — $ 0.91 $ 0.31 $ 726 $ 480 $ — $ 472 $ 0.91 $ — $ 0.91 $ 0.90 $ — $ 0.90 $ 0.31 $ 572 $ 384 $ — $ 379 $ 0.73 $ — $ 0.73 $ 0.73 $ — $ 0.73 $ 0.34 $ 633 441 — 436 0.85 — 0.85 0.84 — 0.84 0.34 As of February 19th, 2018, there were 5,346 stockholders of record.

Internal Control over Financial Reporting. (a) Management’s Annual Report on Internal Control Over Financial Reporting MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING The management of Marsh & McLennan Companies, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures relating to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; the recording of all necessary transactions to permit the preparation of the Company’s consolidated financial statements in accordance with generally accepted accounting principles; the proper authorization of receipts and expenditures in accordance with authorizations of the Company’s management and directors; and the prevention or timely detection of the unauthorized acquisition, use or disposition of assets that could have a material effect on the Company’s consolidated financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Management evaluated the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017 under the supervision and with the participation of the Company’s principal executive and principal financial officers. In making this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control— Integrated Framework issued in 2013. Based on its evaluation, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2017. Deloitte & Touche LLP, the Independent Registered Public Accounting Firm that audited and reported on the Company’s consolidated financial statements included in this annual report on Form 10-K, also issued an audit report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017. 109 (b) Audit Report of the Registered Public Accounting Firm.

Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Marsh & McLennan Companies, Inc. and subsidiaries (the "Company") as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on the criteria established in Internal Control - Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2017, of the Company and our report dated February 22, 2018, expressed an unqualified opinion on those financial statements. Basis for Opinion The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Deloitte & Touche LLP New York, New York February 22, 2018 110 (c) Changes in Internal Control Over Financial Reporting There were no changes in the Company’s internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) or 15d-15(d) under the Securities Exchange Act of 1934 that occurred during the quarter ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
