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.

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%.

OF CAPITAL DEPLOYED IN 2017 TO ACQUISITIONS, 
SHARE REPURCHASES AND DIVIDENDS

Oliver Wyman generated underlying revenue 

growth of 7% for 2017, in line with its strong 

average annual underlying growth of 6%  

since 2010. 

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.

 “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

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.

 “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.

Marsh’s international business.

GUY CARPENTER

Guy Carpenter, the Company’s reinsurance intermediary and advisor, generated approximately 9% of the 
Company's total revenue in 2017. The workforce consists of approximately 2,300 colleagues who provide 
clients with a combination of specialized reinsurance broking expertise, strategic advisory services and 
analytics solutions. Guy Carpenter creates and executes reinsurance and risk management solutions for 
clients worldwide through risk assessment analytics, actuarial services, highly-specialized product 
knowledge and trading relationships with reinsurance markets. Client services also include contract and 
claims management and fiduciary accounting.

Acting as a broker or intermediary on all classes of reinsurance, Guy Carpenter places two main types of 
property and casualty reinsurance: treaty reinsurance, which involves the transfer of a portfolio of risks; 
and facultative reinsurance, which involves the transfer of part or all of the coverage provided by a single 
insurance policy.

Guy Carpenter provides reinsurance services in a broad range of specialty practice areas, including: 
agriculture; alternative risk transfer (such as group-based captives and insurance pools); aviation & 
aerospace; casualty clash (losses involving multiple policies or insureds); construction and engineering; 
credit, bond & political risk; cyber; excess & umbrella; flood; general casualty; life, accident & health; 
marine and energy; medical professional liability; professional liability; program manager solutions; 
property; public sector; retrocessional reinsurance (reinsurance between reinsurers); surety (reinsurance 
of surety bonds and other financial guarantees); terror, and workers compensation.

Guy Carpenter also offers clients alternatives to traditional reinsurance, including industry loss warranties 
and, through its licensed affiliates, capital markets alternatives such as transferring catastrophe risk 
through the issuance of risk-linked securities. GC Securities, the Guy Carpenter division of MMC 
Securities LLC and MMC Securities (Europe) Limited, offers corporate finance solutions, including 
mergers & acquisitions and private debt and equity capital raising, and capital markets-based risk transfer 
solutions that complement Guy Carpenter's strong industry relationships, analytical capabilities and 
reinsurance expertise.

Guy Carpenter also provides its clients with reinsurance-related services, including actuarial, enterprise 
risk management, financial and regulatory consulting, portfolio analysis and advice on the efficient use of 
capital. Guy Carpenter's Global Strategic Advisory ("GSA") unit helps clients better understand and 
quantify the uncertainties inherent in their businesses. Working in close partnership with Guy Carpenter 
account executives, GSA specialists help support clients' critical decisions in numerous areas, including 
reinsurance utilization, catastrophe exposure portfolio management, new product and market 
development, rating agency, regulatory and account impacts, loss reserve risk, capital adequacy and 
return on capital.

Compensation for Services in Risk and Insurance Services

Marsh and Guy Carpenter are compensated for brokerage and consulting services through commissions 
and fees. Commission rates and fees vary in amount and can depend on a number of factors, including 
the type of insurance or reinsurance coverage provided, the particular insurer or reinsurer selected, and 
the capacity in which the broker acts and negotiates with clients. 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.

Marsh and Guy Carpenter receive interest income on certain funds (such as premiums and claims 
proceeds) held in a fiduciary capacity for others. For a more detailed discussion of revenue sources and 
factors affecting revenue in our Risk and Insurance Services segment, see Part II, Item 7 ("Management's 
Discussion and Analysis of Financial Condition and Results of Operations") of this report.

Benefits business) and consulting fees. Mercer's Delegated Solutions business and certain of Mercer's 
defined contribution administration services are compensated typically through fees based on assets 
under administration or management. For a majority of the Mercer-managed investment funds, revenue 
received from Mercer's investment management clients as sub-advisor fees is reported in accordance 
with U.S. GAAP, on a gross basis rather than a net basis. 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

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.

Employees

As of December 31, 2017, the Company and its consolidated subsidiaries employed nearly 65,000 
colleagues worldwide, including approximately 35,000 in Risk and Insurance Services and 27,300 in 
Consulting.

Item 1A.      Risk Factors

You should consider the risks described below in conjunction with the other information presented in this 
report. These risks have the potential to materially adversely affect the Company's business, results of 
operations or financial condition.

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.

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.

Item 7.    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.

In 2017, the Company’s results of operations and earnings per share were impacted negatively, in part, 
as a result of two significant items in 2017:

•  U.S. tax reform - On December 22, 2017, the U.S. enacted comprehensive tax legislation 
commonly referred to as the Tax Cuts and Jobs Act (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. 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:

Underlying revenue measures the change in revenue using consistent currency exchange rates, excluding the impact of certain
items that affect comparability such as: acquisitions, dispositions and transfers among businesses. For 2015, the impact of a $37
million gain from the disposal of Mercer's U.S. defined contribution recordkeeping business is included in acquisitions/dispositions
in Mercer's Defined Benefit Consulting & Administration business.

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.

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.

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.

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.

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").

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:

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.

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".

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. See Note 14 ("Claims, Lawsuits and Other 
Contingencies") to the consolidated financial statements included in this report.

MARSH & McLENNAN COMPANIES, INC. 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:

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.

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

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.

The classification of contingent consideration payments in the consolidated statement of cash flows is 
dependent upon whether the payment was part of the initial liability established on the acquisition date 
(financing) or an adjustment to the acquisition date liability (operating). Deferred payments are classified 
as financing activities in the consolidated statements of cash flows.

The following amounts are included in the consolidated statements of cash flows as a financing activity. 
The Company paid deferred and contingent consideration of $136 million in the year ended December 
31, 2017, consisting of deferred purchase consideration of $55 million and contingent purchase 

65

consideration of $81 million. In the year ended December 31, 2016 the Company paid deferred and 
contingent consideration of $98 million, consisting of deferred purchase consideration of $54 million and 
contingent consideration of $44 million, and in the year ended December 31, 2015 the Company paid 
deferred and contingent consideration of $49 million, consisting of deferred purchase consideration of $36 
million and contingent consideration of $13 million.

The following amounts are included in the operating section of the consolidated statements of cash flows. 
For the year ended December 31, 2017, the Company recorded a net charge for adjustments to 
acquisition related accounts of $3 million and contingent consideration payments of $27 million. For the 
year ended December 31, 2016, the Company recorded a net charge for adjustments to acquisition 
related accounts of $9 million and contingent consideration payments of $42 million, and for the year 
ended December 31, 2015 the Company recorded a net charge for adjustments to acquisition related 
accounts of $45 million and contingent consideration payments of $34 million.

The Company had non-cash issuances of common stock under its share-based payment plan of $88 
million, $73 million and $72 million for the years ended December 31, 2017, 2016 and 2015, respectively. 
The Company recorded stock-based compensation expense related to restricted stock units, performance 
stock units and stock options of $149 million, $109 million and $88 million for the years ended 
December 31, 2017, 2016 and 2015, respectively.

In 2015, the consolidated statement of cash flows includes the cash flow impact of discontinued 
operations from indemnification payments related to the Putnam disposition that reduced the net cash 
flow provided by operations by $82 million.

As discussed in Note 1, 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.

4.    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.

The Consulting segment completed three acquisitions during 2017.

•  August – Mercer acquired Jaeson Associates, a Portugal-based talent management consulting 

organization.

•  December – Mercer acquired Promerit AG, a Germany-based consultancy specializing in HR 

digitalization and business and HR transformation and BFC Asset Management Co., Ltd., a 
Japan-based independently owned asset manager, focused on alternative investment strategies.

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.

Total purchase consideration for acquisitions made during 2016 was approximately $901 million, which 
consisted of cash paid of $865 million and deferred purchase and estimated contingent consideration of 
$36 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 2016, the 
Company also paid $54 million of deferred purchase consideration and $86 million of contingent 
consideration related to acquisitions made in prior years.

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.

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.

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.

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:

*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:

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.

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.

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.

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.

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.

The projected benefit obligation, accumulated benefit obligation and fair value of plan assets for the non-
U.S. pension plans with accumulated benefit obligations in excess of plan assets were $1.3 billion, $1.2 
billion and $1.0 billion, respectively, as of December 31, 2017 and $1.2 billion, $1.2 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.

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:

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.

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.

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:

Expected life (in years)
Expected volatility

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.

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.

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.

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:

(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.

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:

The senior notes in the table above are registered by the Company with the Securities and Exchange 
Commission, and are not guaranteed.

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.

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:

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.

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.

15.    Segment Information

The Company is organized based on the types of services provided. Under this structure, the Company’s 
segments are:

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Marsh & McLennan Companies, Inc. 

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Marsh & McLennan Companies, Inc. 
and subsidiaries (the "Company") as of December 31, 2017 and 2016, the related consolidated 
statements of income, comprehensive income, cash flows, and equity for each of the three years in the 
period ended December 31, 2017, and the related notes (collectively referred to as the “financial 
statements”). 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.

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.

(b)  Audit Report of the Registered Public Accounting Firm.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Marsh & McLennan Companies, Inc. 

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.
