We are 76,000 colleagues in four global businesses  

united by a common purpose—to make a difference in  

the moments that matter.

Three commitments unite us as we strive to live our purpose:

SUCCEEDING TOGETHER.  
We are in business to expand what’s possible for our clients 

and each other.

ACCELERATING IMPACT.  
We embrace change and create enduring client value.

ADVANCING GOOD.  
We strive to serve the greater good.

We work with our clients to enable enterprise around the 

world and secure better futures for all.

TO OUR 
SHAREHOLDERS,  
COLLEAGUES AND 
CLIENTS,

2020 was a year when every 
moment mattered. Around the 
world, no organization was 
unaffected or unchanged as we 
all navigated the crisis of a global 
pandemic, a global economic 
crisis, another devastating year in 
a gathering climate crisis, and an 
overdue reckoning with race, equity 
and social justice. No one could plan 
for such a year, but looking back, 
our company was ready.

As we found smarter ways, every day, to accelerate 
impact for our clients, we did the same for our 
communities. From fundraising for medical workers, 
to mask-making, to one colleague who volunteered 
at night as an ambulance responder, we stood up 
for our communities when they needed it most. And 
we didn’t forget each other. Across our company, 
groups of supportive colleagues coalesced to help one 
another balance heightened professional and personal 
demands, organizing everything from online yoga 
classes to children’s reading programs. I’m not only 
proud of our people, I’m inspired by them.

(cid:35)(cid:51)(cid:48)(cid:2362)(cid:48)(cid:65)(cid:48)(cid:57)(cid:63)(cid:62)(cid:2362)(cid:58)(cid:49)(cid:2362)(cid:63)(cid:51)(cid:48)(cid:2362)(cid:59)(cid:44)(cid:62)(cid:63)(cid:2362)(cid:68)(cid:48)(cid:44)(cid:61)(cid:2362)(cid:61)(cid:48)(cid:44)(cid:562)(cid:61)(cid:56)(cid:48)(cid:47)(cid:2362)(cid:63)(cid:51)(cid:44)(cid:63)(cid:2362)(cid:63)(cid:51)(cid:48)(cid:2362)(cid:59)(cid:64)(cid:61)(cid:59)(cid:58)(cid:62)(cid:48)(cid:2362)
that unites our 76,000 colleagues around the world has 
never been more important or more relevant: We make 
a difference in the moments that matter. For 150 years, 
we’ve done just that, helping our clients, our colleagues 
and the communities where we live and work prosper 
amid times of great change and challenge—times like 
these. As 2020 powerfully demonstrated, the age of risk 
has just begun. We will carry forward the best of what 
the year taught us—about the importance of resilience, 
(cid:530)(cid:48)(cid:67)(cid:52)(cid:45)(cid:52)(cid:55)(cid:52)(cid:63)(cid:68)(cid:2991)(cid:2362)(cid:48)(cid:56)(cid:59)(cid:44)(cid:63)(cid:51)(cid:68)(cid:3022)(cid:44)(cid:57)(cid:47)(cid:2362)(cid:45)(cid:64)(cid:52)(cid:55)(cid:47)(cid:2362)(cid:58)(cid:57)(cid:2362)(cid:52)(cid:63)(cid:2362)(cid:66)(cid:52)(cid:63)(cid:51)(cid:2362)(cid:44)(cid:2362)(cid:61)(cid:48)(cid:55)(cid:48)(cid:57)(cid:63)(cid:55)(cid:48)(cid:62)(cid:62)(cid:2362)
spirit of innovation.

It’s an honor to lead such a formidable, resilient 
company, made up of talented and dedicated people.  
I am excited to bring you up to date.

2020 was a crucible that brought out the best in  
Marsh McLennan. It was a year of workarounds—that 
sparked innovation. It was a year of urgency and 
(cid:47)(cid:52)(cid:62)(cid:61)(cid:64)(cid:59)(cid:63)(cid:52)(cid:58)(cid:57)(cid:3022)(cid:63)(cid:51)(cid:44)(cid:63)(cid:2362)(cid:56)(cid:44)(cid:47)(cid:48)(cid:2362)(cid:64)(cid:62)(cid:2362)(cid:49)(cid:44)(cid:62)(cid:63)(cid:48)(cid:61)(cid:2362)(cid:44)(cid:57)(cid:47)(cid:2362)(cid:56)(cid:58)(cid:61)(cid:48)(cid:2362)(cid:530)(cid:48)(cid:67)(cid:52)(cid:45)(cid:55)(cid:48)(cid:2993)(cid:2362) 
It was a year of physical distance—that created 
profound connection.

We found new ways to engage our clients, helping 
them with their challenges as we faced our own. We 
pushed ourselves to innovate for the greater good, 
developing new products and services to address 
the coronavirus pandemic. And we committed to an 
enterprise-wide focus on four critical areas that have 
a dramatic impact on our clients’ businesses and the 
world, where we’re uniquely positioned to bring the 
full power of our collective capability as a company 
to bear: helping to close the world’s protection gaps; 
advancing healthy societies everywhere; building 
climate resilience; and mitigating cyber risk.

INVESTING IN WHAT 
MATTERS MOST

(cid:28)(cid:44)(cid:61)(cid:62)(cid:51)(cid:2362)(cid:28)(cid:46)(cid:27)(cid:48)(cid:57)(cid:57)(cid:44)(cid:57)(cid:3024)(cid:62)(cid:2362)(cid:2997)(cid:2995)(cid:2997)(cid:2995)(cid:2362)(cid:61)(cid:48)(cid:62)(cid:64)(cid:55)(cid:63)(cid:62)(cid:2362)(cid:61)(cid:48)(cid:530)(cid:48)(cid:46)(cid:63)(cid:2362)(cid:58)(cid:64)(cid:63)(cid:62)(cid:63)(cid:44)(cid:57)(cid:47)(cid:52)(cid:57)(cid:50)(cid:2362)
performance in a year for which there was no 
playbook. Our adjusted earnings per share growth 
of 7% is impressive in one of the worst economic 
recessions ever. We delivered overall revenue growth 
of 3%, or 1% on an underlying basis, driven by growth 
of 3% at Marsh and 6% at Guy Carpenter. Revenue 
from our consulting businesses, Mercer and Oliver 
(cid:38)(cid:68)(cid:56)(cid:44)(cid:57)(cid:2991)(cid:2362)(cid:51)(cid:48)(cid:55)(cid:47)(cid:2362)(cid:64)(cid:59)(cid:2362)(cid:66)(cid:48)(cid:55)(cid:55)(cid:2362)(cid:52)(cid:57)(cid:2362)(cid:63)(cid:51)(cid:48)(cid:2362)(cid:46)(cid:52)(cid:61)(cid:46)(cid:64)(cid:56)(cid:62)(cid:63)(cid:44)(cid:57)(cid:46)(cid:48)(cid:62)(cid:2991)(cid:2362)(cid:61)(cid:48)(cid:530)(cid:48)(cid:46)(cid:63)(cid:52)(cid:57)(cid:50)(cid:2362)
their strength and resilience. And we generated 
margin expansion for the 13th year in a row. 

(cid:35)(cid:51)(cid:52)(cid:62)(cid:2362)(cid:59)(cid:48)(cid:61)(cid:49)(cid:58)(cid:61)(cid:56)(cid:44)(cid:57)(cid:46)(cid:48)(cid:2362)(cid:52)(cid:62)(cid:2362)(cid:66)(cid:51)(cid:58)(cid:55)(cid:55)(cid:68)(cid:2362)(cid:47)(cid:64)(cid:48)(cid:2362)(cid:63)(cid:58)(cid:2362)(cid:63)(cid:51)(cid:48)(cid:2362)(cid:50)(cid:61)(cid:52)(cid:63)(cid:2991)(cid:2362)(cid:530)(cid:48)(cid:67)(cid:52)(cid:45)(cid:52)(cid:55)(cid:52)(cid:63)(cid:68)(cid:2362)
and perseverance of our 76,000 colleagues. In March, 
we promised that all jobs and salaries would be secure 
through the thick of the pandemic. This was the year’s 
biggest decision, and the easiest one. It was clear that 
our clients were going to need us as never before.  
We stood by our people and they stood by our 
clients—and each other.

(cid:30)(cid:64)(cid:61)(cid:2362)(cid:55)(cid:58)(cid:57)(cid:50)(cid:62)(cid:63)(cid:44)(cid:57)(cid:47)(cid:52)(cid:57)(cid:50)(cid:2362)(cid:529)(cid:57)(cid:44)(cid:57)(cid:46)(cid:52)(cid:44)(cid:55)(cid:2362)(cid:59)(cid:51)(cid:52)(cid:55)(cid:58)(cid:62)(cid:58)(cid:59)(cid:51)(cid:68)(cid:2362)(cid:61)(cid:48)(cid:56)(cid:44)(cid:52)(cid:57)(cid:62)(cid:2362)
unchanged: we balance our short-term needs with 
investing for long-term success. A strong balance 
(cid:62)(cid:51)(cid:48)(cid:48)(cid:63)(cid:2362)(cid:44)(cid:57)(cid:47)(cid:2362)(cid:44)(cid:2362)(cid:47)(cid:52)(cid:65)(cid:48)(cid:61)(cid:62)(cid:52)(cid:529)(cid:48)(cid:47)(cid:2362)(cid:57)(cid:48)(cid:66)(cid:2992)(cid:45)(cid:64)(cid:62)(cid:52)(cid:57)(cid:48)(cid:62)(cid:62)(cid:2362)(cid:59)(cid:52)(cid:59)(cid:48)(cid:55)(cid:52)(cid:57)(cid:48)(cid:2362)(cid:59)(cid:61)(cid:58)(cid:65)(cid:52)(cid:47)(cid:48)(cid:2362)
resilience in a year like 2020 and protect our capacity 
for investment. 

Quarter-to-quarter and year-to-year performance is 
the foundation of our company’s long-term growth. 
It enables strategic hiring, strategic investment in 
transformative technologies and timely acquisitions  
(cid:52)(cid:57)(cid:2362)(cid:59)(cid:61)(cid:58)(cid:56)(cid:52)(cid:62)(cid:52)(cid:57)(cid:50)(cid:2362)(cid:529)(cid:48)(cid:55)(cid:47)(cid:62)(cid:2362)(cid:44)(cid:57)(cid:47)(cid:2362)(cid:56)(cid:44)(cid:61)(cid:54)(cid:48)(cid:63)(cid:2362)(cid:62)(cid:48)(cid:50)(cid:56)(cid:48)(cid:57)(cid:63)(cid:62)(cid:2993)

In 2020, we pressed ahead with key acquisitions, 
notably Marsh McLennan Agency’s (MMA) acquisition 
of Assurance Holdings, just as the pandemic struck the 
US. It turned out to be a record year for MMA in terms 
of acquired revenue, as we ultimately completed eight 
transactions representing approximately $235 million 
of annualized revenue. MMA now serves more than 
200,000 clients in the US.

We continued to invest in our digital and technological 
capabilities, including ongoing investments in the 
InsurTech space and more robust client solutions such 
as LINQ, a digital experience that gives Marsh clients 
24/7 access to insurance policies, programs and 
exposure information.

We moved aggressively on costs and enhanced 
liquidity by establishing a new credit facility and 
issuing additional long-term debt. By year-end we had 
actually reduced debt by approximately $650 million, 
in keeping with our commitment to deleverage 
following our 2019 acquisition of Jardine Lloyd 
Thompson. We also raised our dividend for the 11th 
consecutive year.

With the heavy lifting from our combination with 
JLT largely behind us, and having delivered on 
every promise we made when we announced the 
acquisition, Marsh McLennan emerged from 2020 
stronger than we were when we went in—stronger 
(cid:529)(cid:57)(cid:44)(cid:57)(cid:46)(cid:52)(cid:44)(cid:55)(cid:55)(cid:68)(cid:2991)(cid:2362)(cid:62)(cid:63)(cid:61)(cid:58)(cid:57)(cid:50)(cid:48)(cid:61)(cid:2362)(cid:58)(cid:59)(cid:48)(cid:61)(cid:44)(cid:63)(cid:52)(cid:58)(cid:57)(cid:44)(cid:55)(cid:55)(cid:68)(cid:3022)(cid:44)(cid:57)(cid:47)(cid:2362)(cid:66)(cid:52)(cid:63)(cid:51)(cid:2362)(cid:44)(cid:2362)(cid:56)(cid:58)(cid:61)(cid:48)(cid:2362)
(cid:64)(cid:57)(cid:52)(cid:529)(cid:48)(cid:47)(cid:2362)(cid:46)(cid:64)(cid:55)(cid:63)(cid:64)(cid:61)(cid:48)(cid:2993)

We’re executing well, bolstered by our pressure-tested 
ability to work in new and different ways to provide 
better outcomes for our clients and our colleagues.

An antidote to uncertainty

Oliver Wyman’s Pandemic Navigator is part of a fully integrated 

framework that connects pandemic forecasts and scenarios to 

economic and business outcomes. We use it to help clients across 

industries and regions—hospitals, airlines, banks and other 

(cid:45)(cid:64)(cid:62)(cid:52)(cid:57)(cid:48)(cid:62)(cid:62)(cid:48)(cid:62)(cid:2991)(cid:2362)(cid:52)(cid:57)(cid:46)(cid:55)(cid:64)(cid:47)(cid:52)(cid:57)(cid:50)(cid:2362)(cid:58)(cid:64)(cid:61)(cid:2362)(cid:58)(cid:66)(cid:57)(cid:3022)(cid:44)(cid:47)(cid:53)(cid:64)(cid:62)(cid:63)(cid:2362)(cid:529)(cid:57)(cid:44)(cid:57)(cid:46)(cid:52)(cid:44)(cid:55)(cid:2362)(cid:59)(cid:55)(cid:44)(cid:57)(cid:62)(cid:2362)(cid:44)(cid:57)(cid:47)(cid:2362)(cid:62)(cid:64)(cid:59)(cid:59)(cid:55)(cid:68)(cid:2362)

chains, understand future demand recovery patterns and develop 

return-to-workplace strategies, among other things. Government 

clients rely on the Pandemic Navigator’s proprietary data and 

analytics to assess how reopening plans will affect virus spread  

and local hospital capacity.

MORE THAN THE  
SUM OF OUR PARTS

Clients turn to Marsh McLennan for our expertise 
and our unique scope across risk, strategy and 
people—the three things all organizations have 
to get right. Every day, thousands of our colleagues 
around the world provide specialized guidance and 
solutions across every aspect of these critical areas, 
in virtually every industry segment. 

Our deep expertise and capabilities help clients 
(cid:62)(cid:58)(cid:55)(cid:65)(cid:48)(cid:2362)(cid:62)(cid:59)(cid:48)(cid:46)(cid:52)(cid:529)(cid:46)(cid:2362)(cid:46)(cid:51)(cid:44)(cid:55)(cid:55)(cid:48)(cid:57)(cid:50)(cid:48)(cid:62)(cid:2362)(cid:44)(cid:57)(cid:47)(cid:2362)(cid:62)(cid:48)(cid:52)(cid:69)(cid:48)(cid:2362)(cid:58)(cid:57)(cid:48)(cid:2992)(cid:58)(cid:49)(cid:2992)(cid:44)(cid:2992)(cid:54)(cid:52)(cid:57)(cid:47)(cid:2362)
opportunities. At the same time, the challenges faced 
by our clients today are increasingly complex and 
interdependent. To navigate this shifting landscape  
of interconnected needs, our clients require  
more comprehensive solutions—from across  
our businesses. 

The pandemic acted as a natural accelerant for 
cross-business innovation and collaboration. Within 
(cid:56)(cid:58)(cid:57)(cid:63)(cid:51)(cid:62)(cid:2362)(cid:58)(cid:49)(cid:2362)(cid:18)(cid:30)(cid:37)(cid:24)(cid:19)(cid:3024)(cid:62)(cid:2362)(cid:58)(cid:57)(cid:62)(cid:48)(cid:63)(cid:2991)(cid:2362)(cid:28)(cid:48)(cid:61)(cid:46)(cid:48)(cid:61)(cid:2362)(cid:28)(cid:44)(cid:61)(cid:62)(cid:51)(cid:2362)(cid:17)(cid:48)(cid:57)(cid:48)(cid:529)(cid:63)(cid:62)(cid:2362)
introduced a supplemental insurance product for 
individuals in Italy affected by the virus; similar 
products are now available in 25 markets around 
the world. Marsh advocated early and often on 
behalf of clients, urging leaders in the US, in Europe 
and around the world to consider a public-private 
partnership (PPP) for pandemic risk insurance; 
now Marsh, Guy Carpenter and Oliver Wyman are 
(cid:55)(cid:48)(cid:44)(cid:47)(cid:52)(cid:57)(cid:50)(cid:2362)(cid:63)(cid:51)(cid:48)(cid:2362)(cid:66)(cid:44)(cid:68)(cid:2362)(cid:63)(cid:58)(cid:2362)(cid:45)(cid:64)(cid:52)(cid:55)(cid:47)(cid:2362)(cid:61)(cid:48)(cid:62)(cid:52)(cid:55)(cid:52)(cid:48)(cid:57)(cid:46)(cid:48)(cid:2362)(cid:63)(cid:58)(cid:2362)(cid:63)(cid:51)(cid:48)(cid:2362)(cid:529)(cid:57)(cid:44)(cid:57)(cid:46)(cid:52)(cid:44)(cid:55)(cid:2362)

Pandemic Navigator, a leading disease-progression

leaders and policymakers to guide key decisions 
and applied by frontline data sources such as the US 
Centers for Disease Control and Prevention. All of 
our businesses are collaborating on holistic cyber 
advisory and insurance solutions for a suddenly 
virtual world.

As we continue to enhance the guidance and 
solutions we offer to our clients, we’re organizing 
ourselves internally to align functions such as HR 
and technology to partner more closely with our 
businesses to deliver on their priorities. Wherever 
it makes sense, functional activities that are further

None of us hopes to repeat  
2020, but we’re eager to carry 
forward the momentum and  
positive change we’ve created.

IT STARTS WITH US

Our ability to shape our company to meet new challenges, 
seek new opportunities and create new possibilities 
comes down to our colleagues and our culture.

our company. From the outset of the pandemic, we

time as an enterprise, we’ve conducted an Internal 
Labor Market (ILM) analysis to better understand the 
dynamics of how and why our colleagues advance, 
perform, stay and leave—and we are holding ourselves 
accountable to improve our I&D metrics and reporting. 
We’ve launched new initiatives to support career 
development, connection and empowerment for our 
Black colleagues, and we now will require all leaders 
and managers to undergo training on unconscious 
bias, allyship and inclusive leadership. Finally, we’ve 
committed $5 million over the next three years to 
organizations that advocate for equity for the Black 
community—including doubling our company match of 
colleague donations to organizations that advocate for

Although our work to progress inclusion and equity 
for all under-represented colleagues, everywhere, 
is ongoing, it was gratifying to be recognized again 
by both the Bloomberg Gender-Equality Index and 
Human Rights Campaign for our efforts over the past 
year. The most meaningful recognition, however, 
came from within our organization: even in the midst 
of the most unrelenting year in recent memory,  
we saw record colleague-engagement scores across 
our enterprise. 

As we work to advance good on behalf of our 
colleagues and our company, we remain focused on 
the larger world around us. In 2020, we strengthened 
our commitment to a better, sustainable future for all 

by implementing enterprise-wide Client Engagement 
Principles that support sustainable development 
goals in vital areas such as affordable healthcare, 
gender equality and climate-change mitigation. 
Guided by our Environment, Social and Governance 
(ESG) committee, we also announced our support 
for the recommendations of the Task Force on 
Climate-related Financial Disclosures (TCFD), a set 
of voluntary guidelines designed to help companies 
(cid:52)(cid:47)(cid:48)(cid:57)(cid:63)(cid:52)(cid:49)(cid:68)(cid:2362)(cid:44)(cid:57)(cid:47)(cid:2362)(cid:47)(cid:52)(cid:62)(cid:46)(cid:55)(cid:58)(cid:62)(cid:48)(cid:2362)(cid:63)(cid:51)(cid:48)(cid:2362)(cid:59)(cid:58)(cid:63)(cid:48)(cid:57)(cid:63)(cid:52)(cid:44)(cid:55)(cid:2362)(cid:529)(cid:57)(cid:44)(cid:57)(cid:46)(cid:52)(cid:44)(cid:55)(cid:2362)(cid:52)(cid:56)(cid:59)(cid:44)(cid:46)(cid:63)(cid:62)(cid:2362)

Celebrating 150 years  
of shaping change

Few enterprises endure, let alone prosper, for a 
century and a half. Our predecessors helped our 
clients navigate through world wars, depressions 
and, yes, pandemics. From our very beginning, we 
developed unique solutions and markets to address 
complex issues. We helped enable the development 
of major industries by creating insurance solutions 
for the automobile, telephone and electric power 
sectors. We pioneered innovative pension products 
that enhance retirement security.

protection programs. Today, we are boldly working 
with governments around the world on a new type of 
public-private partnership to help address systemic 
risk from pandemics. We are also at the forefront of 
tackling societal challenges such as cybersecurity, the 
protection gap, healthy societies, the retirement gap 
and climate resilience.

We intend to use the occasion of our 150th 
anniversary to celebrate our history, chart our 
future and demonstrate in deeds our commitment 
to the community. To that end, we announced  
in January that we have committed to be carbon-
neutral as a company in 2021 and will reduce  
our carbon emissions by 15% by 2025. Over the 
balance of the year, we will roll out other initiatives, 
including fellowships for racial and social justice. 
And one thing that Marsh McLennan will never 
change: we put clients at the center of everything 
that we do.

LOOKING FORWARD

These are exciting times for Marsh McLennan. Decision-makers and markets don’t like 
uncertainty, but it’s the starting place for most of our work. We are—as individuals and 
as a company—at home in the moments when there are more questions than answers.

The challenges that came to the fore in the past year will be prolonged and solutions won’t 
be simple. As highlighted in the 2021 Global Risks Report prepared by the World Economic 
Forum with the support of Marsh McLennan and other partners, disparities brought to light 
by the pandemic and the acceleration of risks such as cyber and climate must be carefully 
and creatively managed to produce a more sustainable and resilient future.

(cid:3025)(cid:38)(cid:51)(cid:58)(cid:55)(cid:48)(cid:2362)(cid:48)(cid:57)(cid:63)(cid:48)(cid:61)(cid:59)(cid:61)(cid:52)(cid:62)(cid:48)(cid:3026)(cid:2362)(cid:44)(cid:59)(cid:59)(cid:61)(cid:58)(cid:44)(cid:46)(cid:51)(cid:48)(cid:62)(cid:2362)(cid:63)(cid:51)(cid:44)(cid:63)(cid:2362)(cid:55)(cid:48)(cid:65)(cid:48)(cid:61)(cid:44)(cid:50)(cid:48)(cid:2362)(cid:58)(cid:64)(cid:61)(cid:2362)(cid:48)(cid:67)(cid:59)(cid:48)(cid:61)(cid:63)(cid:52)(cid:62)(cid:48)(cid:2362)(cid:52)(cid:57)(cid:2362)(cid:57)(cid:48)(cid:66)(cid:2362)(cid:66)(cid:44)(cid:68)(cid:62)(cid:2362)(cid:44)(cid:46)(cid:61)(cid:58)(cid:62)(cid:62)(cid:2362)(cid:61)(cid:52)(cid:62)(cid:54)(cid:2991)(cid:2362)
strategy and people are already creating new possibilities for our clients and new 
opportunities for our company. We also see a more digital future for our businesses and 
industries—and we’re strongly positioned to play a meaningful role in shaping it. If it helps  
a client, we will do it. If it changes what’s possible in an industry, we will be out front.

We have the capacity to enable new futures—for our clients, our colleagues and our 
communities—because of our proven ability to deliver excellent performance quarter 
after quarter, year in and year out. Along with teaching us lessons in resilience, 2020 
(cid:51)(cid:48)(cid:55)(cid:59)(cid:48)(cid:47)(cid:2362)(cid:45)(cid:61)(cid:52)(cid:57)(cid:50)(cid:2362)(cid:44)(cid:45)(cid:58)(cid:64)(cid:63)(cid:2362)(cid:44)(cid:2362)(cid:49)(cid:44)(cid:62)(cid:63)(cid:48)(cid:61)(cid:2991)(cid:2362)(cid:530)(cid:44)(cid:63)(cid:63)(cid:48)(cid:61)(cid:2991)(cid:2362)(cid:56)(cid:58)(cid:61)(cid:48)(cid:2362)(cid:46)(cid:61)(cid:48)(cid:44)(cid:63)(cid:52)(cid:65)(cid:48)(cid:2362)(cid:28)(cid:44)(cid:61)(cid:62)(cid:51)(cid:2362)(cid:28)(cid:46)(cid:27)(cid:48)(cid:57)(cid:57)(cid:44)(cid:57)(cid:3006)(cid:2362)(cid:66)(cid:48)(cid:3024)(cid:65)(cid:48)(cid:2362)(cid:57)(cid:48)(cid:65)(cid:48)(cid:61)(cid:2362)(cid:45)(cid:48)(cid:48)(cid:57)(cid:2362)
better positioned to make a difference.

None of this just happens by itself. We have been able to act with urgency and boldness 
because we have a Board of Directors whose wisdom guides our steps. I would like  
to thank Ed Hanway, our Independent Chairman, and all the Directors for their 
steadfastness in a year like no other.

Thank you to our clients for your trust when so much was at stake, and to our 76,000 
colleagues. In both cases, our work together was virtual, but our partnership was closer 
than ever. Finally, I thank our investors. At Marsh McLennan, we talk a lot about change 
and new possibilities—and it is your farsightedness that enables them all.

Great challenges are ahead, to be sure, but we will embrace them—as we’ve done since 
1871—because we know how to help shape outcomes that make organizations more 
successful and societies more resilient. Our work continues.

Best regards,

Dan

the dignity and worth of every 
person. We work to advance 
human rights and social and 
workplace equality everywhere

possibilities because of who 
they are or the circumstances 
that surround them.

WE CHAMPION  

liberal democracy and the 
power of free enterprise to

GUY CARPENTER

Guy Carpenter, the Company’s reinsurance intermediary and advisor, generated approximately 10% of
the Company's total revenue in 2020. Currently, approximately 3,100 Guy Carpenter colleagues 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 casualty and life / health 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 centers of excellence and segments,
including: Automobile / Motor, Aviation, Crop/Agriculture, Cyber, D&O/Non-Medical Professional,
Engineering / Construction, Environmental, GL & Umbrella, Health, Life, Marine and Energy, Medical
Professional, Mortgage, Political Risk & Trade Credit, Program Manager Solutions, Property, Public
Sector, Retrocessional Reinsurance, Surety, Terror, and Workers Compensation / Employer Liability.

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; compensation for administrative and other services (including
fees for services provided to or on behalf of insurers 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,
primarily driven by MMA and 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.

Compensation for Services in Consulting

Mercer and Oliver Wyman Group are compensated for advice and services primarily through fees paid by
clients. In the majority of cases, Mercer's Health business is also compensated through commissions for
the placement of insurance contracts and supplemental compensation from insurers based on such
factors as volume, growth of accounts, and total retention of accounts placed by Mercer. Mercer may
receive commissions in other parts of its business, such as its Private Client Services business and
certain financial advice businesses. Mercer's investments business and certain of Mercer's administration
services are compensated typically through fees based on assets under administration or management or
fee per member. 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.
Across most jurisdictions we are also subject to various data privacy laws and regulations that apply to
personal information belonging to our clients, their employees and third parties, as well as our own
colleagues. In addition, we are subject to various financial crime laws and regulations through our
activities, activities of associated persons, the products and services we provide and our business and
client relationships. Such laws and regulations relate to, among other areas, sanctions and export control,
anti-bribery, anti-corruption, anti-money-laundering and counter-terrorist financing. See Part I, Item 1A

7

("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.

In 2005, the Insurance Mediation Directive which, as from October 1, 2018 has been superseded by the
Insurance Distribution Directive, was adopted by the United Kingdom and 27 other European Union
Member States. Its implementation gave powers to the Financial Services Authority ("FSA"), the United
Kingdom regulator at the time, to expand its responsibilities in line with the Financial Services and
Markets Act (2000), 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 and introducing
broker in the United States. 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, investment adviser and
member of FINRA and SIPC JSL Securities, Inc., a SEC registered broker-dealer and member of FINRA,
SIPC and the Municipal Securities Rulemaking Board and Centurion Asset Management LLC, a SEC
registered investment adviser, primarily in connection with retirement, executive compensation and
benefits consulting and advisory services to qualified and non-qualified benefits plans, companies and
executives and personal wealth management. 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, MMA Securities LLC, JSL Securities, Inc. and
Centurion Asset Management LLC are indirect, wholly-owned subsidiaries of Marsh & McLennan
Companies, Inc.

Consulting. Mercer's retirement-related consulting and investment services are subject to pension law
and financial regulation in many countries. Depending on the country, Mercer may rely on licensed
colleagues or registered legal entities to engage in these services, or may utilize other MMC entities or
external third parties. In addition, trustee services, investment services (including advice to persons,
institutions and other entities on the investment of pension assets and assumption of discretionary

8

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 Investments LLC,
(formerly Mercer Investment Management, Inc.), an SEC-registered investment adviser, which
consolidated the activities of each of Mercer’s affiliated investment adviser entities in the United States
(including Mercer Investment Consulting LLC and Pavilion Advisory Group) in 2019. Mercer Trust
Company, a limited purpose New Hampshire chartered trust bank, may also provide services for certain
clients of Mercer’s 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 provides annuity buy-out support
that is subject to regulations (for example, in the U.S., state insurance licensing regulations and ERISA).
Mercer uses the services of MMC Securities LLC to provide certain services, including executive benefit
and compensation services and securities dealing 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.

COMPETITIVE CONDITIONS

The Company faces significant 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. As the Company has clients across various
geographies, industries and scale, the competitive landscape is complex and varies across these
numerous markets. 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 United Kingdom, 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 traditional third-party insurance, thereby reducing
in some cases their need for third-party 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

9

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), investment management firms 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 17 to the consolidated financial statements
included under Part II, Item 8 of this report.

HUMAN CAPITAL

As a professional services firm, we believe the health of our business relies on the strength of our
workforce. Our shared purpose is to make a difference in moments that matter, helping clients meet the
challenges of our time. Measurement of our talent outcomes are, therefore, not just a human capital
priority, but a business imperative.

For detailed information regarding our human capital management, we encourage investors to visit
https://www.mmc.com/about/esg.html for our consolidated environmental, social and governance ("ESG")
report to be published in the first quarter 2021. The information on this website, and in the ESG report,
does not constitute, and should not be viewed as, incorporation by reference of the information contained
on, or available through, the website or the report and does not form part of this Form 10-K.

Our People. As of December 31, 2020, the Company and its consolidated subsidiaries employed 76,000
colleagues worldwide, including approximately 44,100 in Risk and Insurance Services and 29,700 in
Consulting. Two-thirds of our global workforce are located in either North America or Europe. While these
remain our largest work regions, we have also grown our presence in Asia-Pacific and the Middle East
over the last several years. Women comprise more than half of our global enterprise workforce, and
approximately 30% of our senior leaders are women. In the United States, where we have the most
complete data through workforce self-identification of race and ethnicity, approximately 1 in 4 U.S.
colleagues and 14% of U.S. senior leaders identify as non-White.

Our Governance. The Chief People Officer is responsible for developing and executing our enterprise
people strategy. This includes the attraction, recruitment, hiring, development and engagement of talent to
deliver on our strategy and the design of colleague total rewards programs. The Chief People Officer and
the Chief Inclusion & Diversity Officer are responsible for developing and integrating our diversity and
inclusion approach into our strategy.

Our ESG Committee and Compensation Committee of the board of directors have oversight of these
initiatives. The Compensation Committee has responsibility to review certain key human resource
strategic activities, including those relating to diversity, training and recruitment. The Compensation
Committee coordinates with the ESG Committee on diversity initiatives and both committees receive
reports at least annually on diversity and inclusion from the Company’s Chief People Officer. The Chief
Executive Officer and Chief People Officer regularly update our board of directors, the ESG Committee
and the Compensation Committee on the Company’s human capital trends and activities.

Diversity & Inclusion. Our Company’s greatest strength is the collective talent of our people. We believe
the more diverse our backgrounds and experiences, the more we can achieve together working side by
side. We seek capable, creative and fair-minded people who can help us enable client success, find
smarter ways to do things and live our Code of Conduct, The Greater Good. We believe that inclusion
means more than acceptance—it means belonging. Over the last year, we have taken several concrete
actions to further goals, including the formation of a Race Advisory Council to advise our Executive
Committee and help amplify diverse perspectives in decision-making. Other initiatives included the design
of a new learning and sponsorship program to help underrepresented colleagues strengthen leadership
skills, as well as the creation of various forums and networks to promote ongoing candid conversations
within the organization.

Talent Development. We strive to create an environment where individuals and teams can perform to
their highest potential and where career growth and mobility are encouraged and supported. We are
committed to helping colleagues perform at their best by encouraging regular discussions about their

10

goals, performance, career aspirations and development opportunities. We also recognize the importance
of our 13,000 people managers in their crucial roles for reviewing our talent pipeline and have given them
increased support and opportunities for promoting the professional and personal growth of their teams. In
addition, we offer more than 16,000 individual learning courses as part of continuous learning to help our
colleagues grow and develop. In 2020, we published a set of People Manager Practices, centered around
managing inclusively, that define what effective people management looks like. Managers also have
access to our dedicated People Manager Hub, a one-stop source of information and community for all
people managers globally.

Colleague Engagement. Each year we ask our colleagues to share their views on working at Marsh &
McLennan through a company-wide engagement survey. Developed internally by our Global Talent
Development team, the survey methodology has been consistent since 2011, with updates to specific
questions as necessary. A third-party administers our survey in order to maintain confidentiality of
responses. In 2020, a record number of colleagues completed the survey. As in the past, we continue to
use the survey responses to help inform the ongoing development of a vibrant and inclusive culture.

Health and Wellbeing. As a company, our success depends on the health and wellbeing of our
colleagues—we want to support our colleagues with resources, protection and peace of mind to live
healthy lives. We offer comprehensive health insurance, including medical coverage and other core health
benefits based on the market. We also prioritize our colleagues’ mental wellness, including 24/7 access to
an Employee Assistance Program for confidential counselling on personal issues for over 80 percent of
our colleagues and their eligible family members, and critical incident support in countries where a
disaster has occurred. In addition, we offer competitive time-off benefits, including a paid day off each
year to volunteer.

Supporting our colleagues as they navigate the unprecedented challenges of COVID-19 has been our
highest priority in 2020 and our teams have responded by working in innovative ways. Refer to "Recent
Developments" included in Item 7, "Management’s Discussion and Analysis of Financial Condition and
Results of Operations" for information on our response to the COVID-19 pandemic.

Total Rewards. We recognize how important it is to be financially secure through employment, so we
offer competitive rewards to help build colleagues’ personal wealth and improve their financial wellbeing.
Base pay is just the start. Through our annual bonus program, we encourage performance that aligns with
the Company’s interests by providing eligible colleagues with discretionary awards. We also offer various
incentives in certain circumstances, such as sales incentives and long-term incentives to roles that have a
significant impact on our long-term performance designed to foster the Company’s long-term success.
Our robust offerings also include retirement benefits, savings and stock investment plans in certain
jurisdictions.

•

The COVID-19 pandemic could have a material adverse effect on our business operations,
results of operations, cash flows and financial position;

RISKS RELATING TO THE COMPANY GENERALLY

Macroeconomic Risks

The COVID-19 pandemic could have a material adverse effect on our business operations, results
of operations, cash flows and financial position.

Global health concerns relating to the ongoing COVID-19 pandemic and related government actions
taken to reduce the spread of the virus have had a dramatic impact on the macroeconomic environment,
and the outbreak continues to materially increase economic uncertainty and reduce economic activity.

The outbreak has resulted in authorities implementing numerous measures to try to contain the virus,
such as travel bans and restrictions, quarantines, shelter in place or total lock-down orders and business
limitations and shutdowns. Such measures have significantly contributed to decreased levels of business
activity of our clients and the industries and markets that we serve. Governments around the globe have
taken steps to mitigate some of the more severe anticipated economic effects of the virus, but there can
be no assurance that such steps will be effective or achieve their desired results in a timely fashion.

The outbreak has adversely impacted and is likely to further adversely impact our workforce and
operations and the operations of our clients, third-party vendors and business partners. The spread of
COVID-19 has caused us to modify our business practices (including transitioning substantially all of our
colleagues to a remote work environment, restricting colleague travel, developing social distancing plans
for our colleagues and cancelling physical participation in meetings, events and conferences), and we

15

may take further actions as may be required by government authorities or as we determine are in the best
interests of our colleagues, clients and business partners. There is no certainty how long such policies will
remain in effect or that such measures will be sufficient to mitigate the risks posed by the virus or will
otherwise be satisfactory to government authorities.

The ongoing impacts of COVID-19 may affect our ability to generate new business, our overall level of
profitability and cash flow, and our liquidity due to a number of macroeconomic and operational factors.
Such factors may include:

•

•

•

•

•

•

•

•

•

•

in our Risk and Insurance Services segment, a reduction in demand, pricing and commission for
specific lines of coverage most directly affected by COVID-19;

in our Consulting segment, a reduction in fees or commission due to lower demand for our
services as clients cut back on expenses; the impact on our business model for delivering
services to clients due to restrictions on travel and movement, and guidance around social
distancing; and the impact on profitability and margin of not achieving or maintaining adequate
utilization and pricing rates;

the timeliness and ultimate collectability of our receivables, including as a result of deferrals of
premium payments directed by government authorities, which affects our ability to generate
sufficient cash flows;

the impact of disruption in the credit or financial markets, or changes to our credit ratings, which
may impact our ability to access capital or repay our significant outstanding indebtedness on
favorable terms and our compliance with the covenants contained in the agreements that govern
our indebtedness;

an increase in errors & omissions claims related to losses incurred by policyholders arising from
the pandemic;

the impact of financial market volatility, including our ability to execute timely trades in light of
increased trading volume, which may reduce assets under management and revenue for
Mercer’s Investments business;

failure of third parties upon which we rely to meet their obligations to us, or significant disruptions
in their ability to meet those obligations in a timely manner, which may be caused by their own
financial or operational difficulties;

the impact of an extended period of remote work arrangements on our business continuity plans,
and our ability to continue to provide services to our clients;

increased risk of phishing and other cybersecurity attacks or unauthorized dissemination of
personal, confidential, proprietary or sensitive data caused by remote work arrangements; and

the potential effects on our internal controls including those over financial reporting as a result of
remote work arrangements that are applicable to our team members and business partners.

These factors may remain prevalent for a significant period of time and may continue to adversely affect
our business, results of operations and financial condition even after the COVID-19 pandemic subsides.
For the year ended December 31, 2020, the COVID-19 pandemic had an adverse impact to the
Company’s revenue growth, primarily in our businesses that are discretionary in nature, which was partly
mitigated through disciplined expense management by implementing restrictions on travel and other cost
containment measures. However impacts from COVID-19 in 2020 may not be representative of future
conditions. The extent to which the COVID-19 outbreak continues to impact our business, results of
operations and financial condition will depend on future developments, which remain highly uncertain and
are difficult to predict, including the duration and spread of the outbreak, its severity and strain mutations,
the actions to contain the virus and the development and availability of effective treatments and vaccines,
and how quickly and to what extent normal economic and operating conditions can resume. Even after
the COVID-19 outbreak subsides, we may continue to experience materially adverse impacts to our
business as a result of the virus’s global economic impact, including the availability of credit, adverse
impacts on our liquidity and any recession that has occurred or may occur in the future.

There are no comparable recent events that provide guidance as to the effect the spread of COVID-19 as
a global pandemic may have, and, as a result, the ultimate impact of the outbreak is highly uncertain and

16

subject to change. We do not yet know the full extent of the impacts on our business, our operations or
the global economy as a whole. However, the effects could have a material impact on our results of
operations and heighten many of our known risks in this section.

Our results of operations and investments 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. In particular, please see above for detailed risks related to the impact of
COVID-19.

In addition, the United Kingdom’s withdrawal from the European Union, referred to as "Brexit," continues
to create political and economic uncertainty, particularly in the United Kingdom and the European Union.
While the British government and the E.U. negotiated terms of the withdrawal in December 2020, the
agreement did not contain resolutions related to financial services. Accordingly, there remains inevitable
uncertainty on the treatment of financial services and the impact of the other terms of the agreement
generally on our businesses.

We have significant operations and a substantial workforce in the U.K. With 12,500 colleagues and
approximately 16% of our revenue from the U.K., the uncertainty surrounding the implementation and
effect of Brexit may cause increased economic volatility, affecting our operations and business. The
effects of Brexit will depend on the agreements the U.K. makes to retain access to European Union
markets and the systems put in place to facilitate future trade and economic relationships. The measures
could potentially disrupt the markets we serve and may cause us to lose clients and colleagues. In
addition, Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as
the U.K. determines which European Union laws to replace or replicate. These developments may have a
material adverse effect on global economic conditions and the stability of financial markets, both in the
U.K. and globally. Any of these factors could affect the demand for our services. Furthermore, currency
exchange rates in GBP and the Euro with respect to each other and the U.S. dollar have already been
adversely affected by these developments. Should this foreign exchange volatility continue, it could cause
volatility in our quarterly financial results.

More generally, 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 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.

Technology, Cybersecurity and Data Protection Risks

Our business performance and growth plans could be negatively affected if we are not able to
develop and implement improvements in technology or respond effectively to the threat of digital
disruption and other technological change.

We depend in large part on our technology systems for conducting business, as well as for providing the
data and analytics we use to manage our business. As a result, our business success is dependent on
maintaining the effectiveness of existing technology systems and on continuing to develop and enhance
technology systems that support our business processes and strategic initiatives in a cost and resource
efficient manner, particularly as our business processes become more digital. We have a number of

17

strategic initiatives involving investments in or partnerships with technology companies as part of our
growth strategy, as well as investments in technology and infrastructure to support our own systems.

These investments may be costly and require significant capital expenditures, may not be profitable or
may be less profitable than what we have experienced historically. In addition, investments in technology
systems may not deliver the benefits or perform as expected, or may be replaced or become obsolete
more quickly than expected, which could result in operational difficulties or additional costs. In some
cases, we also 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 effectively on our strategic initiatives, our business and results of
operations could be adversely impacted.

In addition, 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. In the past few years, there has been
a substantial increase in private equity investments into these Insurtech companies. These players are
focused on using technology and innovation, including artificial intelligence (AI), digital platforms, data
analytics, robotics and blockchain, to simplify and improve the client experience, increase efficiencies,
alter business models and effect other potentially disruptive changes in the industries in which we
operate.

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.

In operating our business and providing services and solutions to clients, we collect, use, store, transmit
and otherwise process certain electronic information, including personal, confidential, proprietary and
sensitive data such as information related to financial records, health care, mergers and acquisitions and
personal data of our clients, colleagues and vendors. 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, as well as the control systems of critical infrastructure
they rely on, such as power grids, are potentially vulnerable to unauthorized access, damage or
interruption from a variety of external threats, including cyberattacks, computer viruses and other
malware, ransomware and other types of data and systems-related modes of attack. 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 or timely
disclosures to the public or law enforcement agencies following any such event, whether due to delayed
discovery or a failure to follow existing protocols.

Cyberattacks are increasing in frequency and evolving in nature. We are at risk of attack by a variety of
adversaries, including state-sponsored organizations, organized crime, hackers or "hactivists" (activist
hackers), through use of increasingly sophisticated methods of attack, including the deployment of
artificial intelligence to find and exploit vulnerabilities, such as “deep fakes”, and long-term, persistent
attacks referred to as advanced persistent threats. These techniques used to obtain unauthorized access
or sabotage systems include, among other things, computer viruses, malicious or destructive code,
ransomware, social engineering attacks (including phishing and impersonation), hacking and denial-of-
service attacks. Because these techniques change frequently and new techniques may not be 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, data unavailability, data corruption or

18

other damage to information technology systems. In addition, remote work arrangements in response to
COVID-19 have increased the risk of phishing and other cybersecurity attacks or unauthorized
dissemination of personal, confidential, proprietary or sensitive data.

As the breadth and complexity of the technologies we use and the software and platforms we develop
continue to grow, including as a result of the use of mobile devices, cloud services, "open source"
software, 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. Our efforts to improve and protect data from compromise may
also identify previously undiscovered instances of security breaches or other cyber incidents. Our policies,
employee training (including phishing prevention training), procedures and technical safeguards may also
be insufficient to prevent or detect improper access to confidential, personal or proprietary information. In
addition, the competition for talent in the data privacy and cybersecurity space is intense, and we may
also be unable to hire, develop or retain suitable talent capable of adequately detecting, mitigating or
remediating these risks.

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
(including encryption of data at rest), heightened monitoring and logging, scanning for source code errors
or deployment of multi-factor authentication, take significant time and resources to deploy broadly, and
such measures may not be deployed in a timely manner or 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
cyberattackers exploit these known vulnerabilities before they have been communicated by vendors or
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.

We have numerous vendors and other third parties who receive personal information from us in
connection with the services we offer our clients. We also use hundreds of IT vendors and software
providers to maintain and secure our global information systems infrastructure. 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
cyberattack involving a vendor or other third party, which could result in a breakdown of such third party’s
data protection processes or the cyberattackers gaining access to our infrastructure through a supply
chain attack. For example, in December 2020, it was widely reported that hackers installed malware into
business software updates provided by SolarWinds. The attack was widespread, affecting public and
private organizations around the world, including several U.S. government agencies. While we do not
believe our operations were affected by this latest attack, it highlighted the vulnerability of IT supply
chains.

We have a history of making acquisitions and investments, and in April 2019 we completed the acquisition
of JLT. The process of integrating the information systems of any businesses we acquire is complex and
exposes us to additional risk. For instance, we may not adequately identify weaknesses and
vulnerabilities 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 cyberattack. In addition, if we discover a historical
compromise, security breach or other cyber incident related to the target’s information systems following
the close of the acquisition, we may be liable and exposed to significant costs and other unforeseen

19

liabilities. 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.

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 or misconfiguration of software or hardware resulting in inadvertent
exposure of personal, sensitive, confidential or proprietary information. Like many companies, we are
subject to social engineering attacks such as regular phishing email campaigns directed at our employees
that can result in malware infections and data loss. 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 personal, sensitive, confidential 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 cyberattack, 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, cyberattacks 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 (GDPR)
and the California Consumer Privacy Act (CCPA), could adversely affect our financial condition,
operating results and our reputation.

Improper disclosure of confidential, personal, or proprietary data could result in regulatory scrutiny, legal
and financial liability, or harm to our reputation. In operating our business and providing services and
solutions to clients, particularly in our Consulting segment, 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, data security and cyber-security. These laws and regulations
are continuously evolving and developing. Some of these laws and regulations are increasing the level of
data handling restrictions, including rules on data localization, all of which could affect our operations and
result in regulatory liability and high fines. In particular, high-profile security breaches at major companies
continue to be disclosed regularly, which is leading to even greater regulatory scrutiny and fines at the
highest levels they have ever been.

The scope and interpretation of the laws that are or may be applicable to us are often uncertain and may
be conflicting. For example, the GDPR, which became effective in May 2018, greatly increased the
European Commission’s jurisdictional reach of its laws and added a broad array of requirements for
handling personal data, such as the public disclosure of data breaches, privacy impact assessments, data
portability and the appointment of data protection officers in some cases. In the U.S., the CCPA came into
effect in January 2019 and introduced several new concepts to local privacy requirements, including
increased transparency and rights such as access and deletion and an ability to opt out of the “sale” of
personal information. Despite a proliferation of regulatory guidance papers, much remains unclear with
respect to how to interpret and implement the GDPR and the CCPA, and that lack of clarity could result in
potential liability for our failure to meet our obligations under the GDPR and the CCPA. Given the breadth
and depth of changes in data protection obligations, including classifying data and committing to a range
of administrative, technical and physical controls to protect data and enable data transfers outside of the
E.U., our compliance with laws such as the GDPR and the CCPA will continue to require time, resources
and review of the technology and systems we use. Further, the European Union Court of Justice's
"Schrems II" decision and Brexit have created uncertainty with regard to the future of the flow of personal
information between the United Kingdom and the E.U., respectively, and that uncertainty may impair our
ability to offer our existing and planned products and services or increase our cost of doing business.

Following the implementation of the GDPR, other jurisdictions have sought to amend, or propose
legislation to amend, their existing data protection laws to align with the requirements of the GDPR with

20

the aim of obtaining an adequate level of data protection to facilitate the transfer of personal data to most
jurisdictions from the E.U. Accordingly, the challenges we face in the E.U. will likely also apply to other
jurisdictions that adopt laws similar to the GDPR or regulatory frameworks of equivalent complexity. For
example, Brazil has enacted its general data protection law, the Lei Geral de Proteção de Dados
Pessoais, which came into effect in August 2020, China has proposed a new comprehensive privacy law,
India is considering a new privacy law, Canada is proposing significant changes to their federal privacy
law and Japan has adopted sweeping changes to its privacy law. In some cases, including China and
India, the laws include data localization elements that will require that certain personal data stay within
their borders.

Looking at the U.S. following the passage of the CCPA, California recently approved a ballot measure that
enacts the California Privacy Rights Act, making extensive modifications to the CCPA. Additionally,
several other states have introduced privacy bills, some more comprehensive than the CCPA. There is
also continued legislative interest in passing a federal privacy law which is likely to accelerate under the
new U.S. administration.

In addition to data protection laws, countries and states in the U.S. are enacting cybersecurity laws and
regulations. For example, the New York State Department of Financial Services issued in 2017
cybersecurity regulations which imposed an array of detailed security measures on covered entities.
These requirements were phased in and the last of them came into effect on March 1, 2019. 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.

Many statutory requirements, both in the United States and abroad, include obligations for companies to
notify individuals of security breaches involving certain personal information, which could result from
breaches experienced by us or our vendors. In addition to government regulation, privacy advocates and
industry groups have and may in the future propose self-regulatory standards from time to time. These
and other industry standards may legally or contractually apply to us, or we may elect to comply with such
standards. We expect that there will continue to be new proposed laws and regulations concerning data
privacy and security, and we cannot yet determine the impact such future laws, regulations and standards
may have on our business.

Furthermore, enforcement actions and investigations by regulatory authorities related to data security
incidents and privacy violations, including a recent focus on website “cookies” compliance in some
countries, continue to increase. Privacy violations, including 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 (if
they fail to meet the standards we impose) could damage our reputation and subject us to significant
litigation, monetary damages, regulatory enforcement actions, fines and criminal prosecution in one or
more jurisdictions. Given the complexity of operationalizing the various privacy laws such as the GDPR
and the CCPA, the maturity level of proposed compliance frameworks and the continued lack of clarity on
how to implement their requirements, we and our clients are at risk of enforcement actions taken by E.U.
and other data protection authorities or litigation from consumer advocacy groups acting on behalf of data
subjects. We may not be able to respond quickly or effectively to regulatory, legislative and other
developments, and these changes may in turn impair our ability to offer our existing or planned products
and services and increase our cost of doing business.

Legal and Regulatory Risks

We are subject to significant uninsured exposures arising from errors and omissions, breach of
fiduciary duty and other claims.
Our businesses 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. For example, these claims may include allegations
related to losses incurred by policyholders arising from the COVID-19 pandemic, or losses from

21

cyberattacks associated with policies where cyber risk was not specifically included or excluded in
policies, commonly referred to as “silent cyber.” In our Consulting segment, where we increasingly act in a
fiduciary capacity through our investments business, such claims could include allegations of damages
arising from the provision of consulting, investments, actuarial, pension administration and other services.
We may also be exposed to claims related to assets or solutions offered by the Consulting segment in
complement to its traditional consulting services. These Consulting segment 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 individual financial
planning advice including investment advice and advice relating to cashing out of defined benefit pension
plans, (v) providing investment advice, including guidance on asset allocation and investment strategy,
and (vi) managing client assets, including the selection of investment managers and implementation of
the client’s investment policy. We provide these services to a broad client base, including clients in the
public sector for our investment services. 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 U.S. generally accepted accounting principles ("U.S.
GAAP"), the Company uses case level reviews by inside and outside counsel, actuarial analysis by Oliver
Wyman, 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 judgment involved in
estimating and establishing liabilities in accordance with U.S. 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.

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, Crimea, Iran, North
Korea, Russia, Syria and Venezuela, 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, cybersecurity, 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. In particular, changes at
regulatory agencies in the U.S. occur through policy and personnel changes following elections, which
often leads to changes involving the level of oversight and focus on businesses and certain industries, in
particular financial services. Accordingly, the expectation is that there will be increased regulatory scrutiny
and enforcement action under the new administration.

22

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 we 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. These inquiries consume significant
management attention, and 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 addition, we may be responsible for the legal and regulatory liabilities of companies that we acquire. In
particular, upon the consummation of the acquisition of JLT, the Company assumed the legal liabilities
and became responsible for JLT’s litigation and regulatory exposures as of April 1, 2019. In the fourth
quarter 2020, the Company recorded a $161 million provision for a legacy JLT matter related to an FCA
review of the suitability of financial advice to individuals for defined benefit pension transfers. Additional
information regarding certain ongoing investigations and certain other legal and regulatory proceedings is
set forth in Note 16 to our consolidated financial statements included under Part II, Item 8 of this report.

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
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.

Our business or reputation could be harmed by our reliance on third-party providers or
introducers.

We currently utilize the services of hundreds of third-party providers to meet the needs of our clients
around the world.

There is a risk that our third-party providers or introducers engage in business practices that are
prohibited by our internal policies or violate applicable laws and regulations, such as the U.S. Foreign
Corrupt Practices Act and the U.K. Anti-Bribery Act.

Competitive Risks

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 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, the general mobility of colleagues and fostering a diverse and inclusive workplace.

23

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.

Failure to maintain our corporate culture could damage our reputation.

We strive to foster a culture in which our colleagues act with integrity and feel comfortable speaking up
about potential misconduct. We are a people business, and our ability to attract and retain colleagues and
clients is dependent upon our commitment to a diverse and inclusive workplace, trustworthiness, ethical
business practices and other qualities. Our colleagues are the cornerstone of this culture, and acts of
misconduct by any colleague, and particularly by senior management, could erode trust and confidence
and damage our reputation among existing and potential clients and other stakeholders.

Increasing scrutiny and changing expectations from investors, clients and our colleagues with
respect to our environmental, social and governance (ESG) practices may impose additional costs
on us or expose us to new or additional risks.

There is increased focus, including from governmental organizations, investors, colleagues and clients,
on ESG issues such as environmental stewardship, climate change, diversity and inclusion, racial justice
and workplace conduct. Negative public perception, adverse publicity or negative comments in social
media could damage our reputation if we do not, or are not perceived to, adequately address these
issues. Any harm to our reputation could impact colleague engagement and retention and the willingness
of clients and our partners to do business with us.

Moreover, as we work to align with the recommendations of the Financial Stability Board's Task Force on
Climate-related Financial Disclosures, (TCFD), the Sustainability Accounting Standards Board (SASB),
and our own ESG assessments and priorities, we expect to expand our public disclosures in these areas,
including providing additional metrics. These metrics, whether it be the standards we set for ourselves or
a failure to meet these metrics, and any failure to achieve progress on our metrics on a timely basis, or at
all, may negatively impact our reputation and our business.

In addition, organizations that provide information to investors on corporate governance and related
matters have developed ratings processes for evaluating companies on their approach to ESG matters,
and unfavorable ratings of our company or our industries may lead to negative investor sentiment and the
diversion of investment to other companies or industries.

We face significant competitive pressures in each of our businesses, including from
disintermediation, as our competitive landscape continues to evolve.

As a global professional services firm, the Company faces 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 clients’ 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.

Across our Risk and Insurance Services segment, we operate in a variety of markets and face different
competitive landscapes. In addition to the challenges posed by capital market alternatives to traditional
insurance and reinsurance, we compete 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. In recent years, private equity sponsors have invested tens of billions of
dollars into the insurance brokerage sector, transforming existing players and creating new ones to
compete with large brokers. 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

24

to traditional brokerage services, including those that rely almost exclusively on technological solutions or
platforms. This competition is intensified by an often "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 that
serve as substitutes for traditional insurance.

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 provide, 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.

In addition, 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.

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, business
process management, 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, and providers of human resource
functions, such as recruiters. Many of these providers are located outside the U.S., which exposes us to
business disruptions and political risks inherent when conducting business outside of the U.S. 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
in services or operations and additional expense.

A failure by the third parties to (i) comply with service level agreements in a high quality and timely
manner, particularly during periods of our peak demand for their services, (ii) maintain adequate internal
controls that may impact our own financial reporting, or (iii) adequately maintain the confidentiality of any
of our data or trade secrets or adequately protect or properly use other intellectual property to which they
may have access, could result in economic and reputational harm to us. These third parties also 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, non-compliance with legal, regulatory or contractual obligations, 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
or data recovery 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, protests or riots, security breach, cyberattack (including
manipulating the control systems of critical infrastructure), 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

25

approximately 3,300 and 5,000 colleagues in those respective locations, 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. Such risks have increased significantly due to extended remote work accommodations as a result
of COVID-19. A cyberattack 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 or our ability to recover data, 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. In the worst case, any
manipulation of the control systems of critical infrastructure may even result in the loss of life.

We regularly assess and take steps to improve our existing business continuity, disaster recovery and
data recovery 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 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.

Acquisitions and Dispositions Risks

We face risks when we acquire businesses.

We have a history of making acquisitions and investments, including a total of 132 in the period from 2013
to 2020. We may not be able to successfully integrate the businesses that we acquire into our own
business, or achieve any expected cost savings or synergies from the integration of such businesses.
Subject to standard contractual protections, we may also be responsible for legacy liabilities of companies
that we acquire. For example, upon the consummation of the acquisition of JLT, the Company assumed
the legal liabilities and became responsible for JLT’s litigation and regulatory exposures as of April 1,
2019.

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. 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.

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
finance and complete the transactions we decide to pursue on favorable terms with positive results.

When we dispose of businesses, we may continue to be subject to certain liabilities of that business after
its disposition relating to the prior 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.

Financial Risks

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, 2020, our receivables for our commissions and fees were
approximately $4.7 billion, or approximately one-quarter of our total annual revenues, and portions of our
receivables are increasingly concentrated in certain businesses and geographies.

26

Macroeconomic or political conditions, such as the impact from COVID-19, 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.

We may not be able to obtain sufficient financing on favorable terms.

The maintenance and growth of our business, including our ability to finance acquisitions, 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, a division of MMC Securities, LLC and MMC Securities (Europe)
Limited also rely on financings by the Company to fund the underwriting of their client's debt and equity
capital raising transactions. We incurred significant debt to finance the JLT Transaction, and 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,
including obligations assumed as part of the JLT Transaction, totaling approximately $19.9 billion, and
related plan assets of approximately $19.1 billion, at December 31, 2020 on a U.S. GAAP basis. As part
of the JLT Transaction, the Company assumed responsibility for a number of pension plans throughout
the world, with $305 million of net pension liabilities as of December 31, 2020 ($1,124 million in liabilities
and $819 million of plan assets as of December 31, 2020). 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' trustees. 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. In addition, the estimated return on plan
assets would likely be impacted by changes in the interest rate environment and other factors, including
equity valuations, since these factors reflect the starting point used in the Company’s projection models.
For example a reduction in interest rates may result in a reduction in the estimated return on plan assets.
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, changes in investment markets that result in lower expected
returns on assets, 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.

Our significant non-U.S. operations expose us to exchange rate fluctuations and various risks that
could impact our business.

27

Approximately 53% of our total revenue reported in 2020 was from business 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. 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.

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;

potential limitations on the clients or industries we serve resulting from increased
regulation or changing stakeholder expectations on ESG issues;

the impact of changes in accounting standards or in our accounting estimates or
assumptions;

the impact on us or our clients of changes in legislation, regulation and legal guidance or
interpretations in the jurisdictions in which we operate, in particular in the U.S. as a result
of the change in presidential administrations;

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;

• 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 COVID-19 and other global health crisis or pandemics, severe
weather, climate change, geopolitical unrest such as protests and riots or other
catastrophic events, since our 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 Company carries a
Stable outlook with S&P and a Negative outlook with Moody's.

If we need to raise capital in the future (for example, in order to maintain adequate liquidity, 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. We would also face the risk of a credit
rating downgrade if we do not retire or refinance the debt to levels acceptable to the credit rating agencies
in a timely manner. Further, a downgrade to a rating below investment-grade could result in greater
operational risks through increased operating costs and increased competitive pressures.

We have significantly increased our debt as a result of the JLT acquisition, which could adversely
affect our financial flexibility.

28

As of December 31, 2020, we had total consolidated debt outstanding of approximately $11.3 billion. In
2019 alone, we incurred $6.5 billion of additional debt to finance the JLT acquisition.

The level of debt outstanding could adversely affect our financial flexibility by reducing our cash flows and
our ability to use cash from operations for other purposes, including working capital, dividends to
shareholders, share repurchases, acquisitions, capital expenditures and general corporate purposes. In
addition, we are subject to risks that, at the time any of our outstanding debt matures, we will not be able
to retire or refinance the debt on terms that are acceptable to us.

The current U.S. tax regime makes our results more difficult to predict.
Our effective tax rate may fluctuate in the future as a result of the current U.S. tax regime enacted as part
of the 2017 Tax Cuts and Jobs Act (the "TCJA") and the continuing issuance of interpretive guidance
related to the TCJA. The TCJA included significant changes in U.S. income tax law that has a meaningful
impact on our provision for income taxes and requires significant judgments and estimates in
interpretation and calculations. The enacted tax legislation included, among other provisions, limitations
on the deductibility of net interest, a tax on Global Intangible Low-Taxed Income ("GILTI"), and the Base
Erosion and Anti-Abuse Tax ("BEAT"). Given the significant complexity of the rules, and the potential for
additional guidance from U.S. Treasury, the Securities and Exchange Commission, the Financial
Accounting Standards Board or other regulatory authorities, 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. In addition, the change in the U.S. presidential
administrations in January 2021 may increase the chance for legislative changes to the TCJA provisions.
In particular, the Biden Administration has proposed changes to the U.S. statutory tax rate and GILTI
which would increase the impact of the provision on our results. As a U.S.-domiciled company, any such
increases would have a disproportionate impact on us compared to our foreign-based competitors.

Global Operations

We are exposed to multiple risks associated with the global nature of our operations.

We conduct business globally. In 2020, approximately 53% 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. The JLT Transaction significantly expanded our non-U.S. operations in
jurisdictions such as the U.K., Asia, South America and Australia, and 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 and the potential imposition of new global minimum tax;

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,

or permanent establishments created due to colleagues traveling to and doing work in

countries where the company has no presence and which are not properly compensated
through transfer pricing;

•

•

our ability to obtain dividends or repatriate funds from our non-U.S. subsidiaries, including
as a result of 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;

potential conflicts of interest that may arise as we expand the scope of our businesses
and our client base;

29

•

•

•

•

•

•

•

•

•

•

international hostilities, international trade disputes, terrorist activities, natural disasters,
pandemics, 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 or legislatively appointed commissions, which
may result in potential modifications to our businesses, 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
sanctions laws relating to countries such as Cuba, Crimea, Iran, North Korea, Russia,
Syria and Venezuela 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;

potential limitations or difficulties in protecting our intellectual property in various foreign
jurisdictions;

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.

RISKS RELATING TO OUR RISK AND INSURANCE SERVICES SEGMENT

Our Risk and Insurance Services segment, conducted through Marsh and Guy Carpenter, represented
60% of the Company's total revenue in 2020. 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 marketplace.

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

30

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 revenue and 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 our 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
insurance companies, separate from retail fees and commissions, has increased in the last several years,
both on an underlying basis and through acquisition and represented approximately 5% of Marsh's
revenue in 2020. 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, panels and other facilities); and (iii) contingent
commissions, primarily at MMA and outside the U.S., paid by insurers based on factors such as volume or
profitability. These other revenue streams present potential regulatory, litigation and reputational risks that
may arise from alleged anti-competitive behavior or conflicts of interest, (including those arising from Guy
Carpenter’s role as intermediary and advisor for insurance companies), and future changes in the
regulatory environment may impact our ability to collect such revenue. 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 40% of our
total revenue in 2020. Our businesses in this segment are subject to particular risks.

Mercer’s Investments 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 Investments business provides clients with investment consulting and investment management
services. As of December 31, 2020, Mercer and its global affiliates had assets under management of
approximately $357 billion worldwide. In the investment consulting business, clients make and implement
their own investment decisions based upon research prepared or advice provided by Mercer. In its
investment management business, Mercer implements the client’s investment policy by engaging,
overseeing and making changes to the third-party asset managers who determine which investments to

31

buy and sell. To effect implementation of a client’s investment policy, Mercer may utilize its "manager of
managers" investment funds.

Mercer’s Investments business is subject to a number of risks, including risks related to litigation, 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 manager research or 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 or direction, 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. Changes in the value levels of equity,
debt, real assets, commodities, foreign exchange or other asset markets, in particular as a result of a
downturn in the global markets, may cause our assets under management, revenue and earnings to
decline. These risks, if realized, could result in significant liability and damage our business.

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
classes, our clients’ or an industry's financial condition or government regulation or an
accelerated trend away from actively managed investments to passively managed investments.

Global economic conditions, particularly the impact of COVID-19 may negatively impact 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 during difficult economic periods. The evolving needs and
financial circumstances of our clients may reduce demand for our consulting services and could adversely
affect 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 Investments business generate 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 Investments 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.
Mercer’s Investments business also could be adversely affected by an accelerated shift away from
actively managed investments to passively managed investments with associated lower fees. 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 of 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 trustees, multi-employer and public clients with actuarial, consulting
and administration services relating to defined benefit pension plans. The nature of our work is complex.
Many clients, particularly in the public sector, have sizeable pension deficits and are subject to impact
from volatility in the global stock markets and interest rate fluctuations. 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 and a continued or accelerated

32

rate of decline in revenues for our defined benefit pension plans business could adversely affect Mercer's
business and operating results. In addition, 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. Our investments services include investment advice and
management relating to defined benefit pension plan assets intended to fund present and future benefit
obligations. Clients dissatisfied with our services have brought, and may bring, significant claims against
us, particularly in the United States and the United Kingdom.

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 retain key colleagues and consulting professionals;

unanticipated changes in the scope of client engagements;

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.

33

Item 2. Properties.

The Company 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.

The Company 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.

We and our subsidiaries are 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 16 to
the consolidated financial statements appearing under Part II, Item 8 ("Financial Statements and
Supplementary Data") of this report.

Item 4. Mine Safety Disclosures.

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 in the areas of risk, strategy and people. The Company’s
76,000 colleagues advise clients in over 130 countries. With annual revenue over $17 billion, the
Company helps clients navigate an increasingly dynamic and complex environment through four market-
leading businesses. Marsh advises individual and commercial clients of all sizes on insurance broking
and innovative risk management solutions. Guy Carpenter develops advanced risk, reinsurance and
capital strategies that help clients grow profitably and pursue emerging opportunities. Mercer delivers
advice and technology-driven solutions that help organizations redefine the world of work, reshape
retirement and investment outcomes, and unlock health and well being for a changing workforce. Oliver
Wyman Group serves as critical strategic, economic and brand advisor to private sector and
governmental clients.

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, wealth and career 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 17 to the consolidated financial statements included in Part II, Item 8 in this
report.

Acquisitions and dispositions impacting the Risk and Insurance Services and Consulting segments are
discussed in Note 5 to the consolidated financial statements.

For information on fiscal 2018 results and similar comparisons, see "Item 7. Management's Discussion
and Analysis of Financial Condition and Results of Operations" of our Form 10-K for the fiscal year ended
December 31, 2019.

This 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.

Business Update Related To COVID-19

In March 2020, the World Health Organization declared the Coronavirus (COVID-19) a pandemic. The
pandemic has impacted essentially every geography in which the Company operates. Governments
implemented various restrictions around the world, including closure of non-essential businesses, travel,
shelter-in-place requirements for citizens and other restrictions. The Company has taken a number of
precautionary steps to safeguard its businesses and colleagues from COVID-19, including implementing
travel restrictions, arranging work from home capabilities and flexible work policies.

In the second and third quarters of 2020, the Company began re-opening offices in various locations
around the world, while ensuring that it continued to adhere to guidelines and orders issued by national,
state and local governments. The timing of additional office re-openings will vary based on the conditions
and restrictions in each location. In the fourth quarter, there was a surge in COVID-19 infections in many
parts of the world, leading to renewed lock-downs and increased government restrictions. The safety and
well-being of our colleagues continues to be our first priority. Several vaccines have been or are in various
stages of approval. However, the speed of distribution and the impact on colleagues' ability to return to
the office remains uncertain. The vast majority of the Company’s colleagues have continued and will
continue working in a remote work environment for most of 2021. The Company expects it will continue its
ability to service clients effectively while colleagues remain in a remote work environment.

37

For the year ended December 31, 2020, the COVID-19 pandemic had an adverse impact on the
Company’s revenue growth, primarily in our businesses that are discretionary in nature, which was partly
mitigated through disciplined expense management by implementing restrictions on travel and other cost
containment measures. However, the ultimate extent of the COVID-19 impact to the Company will depend
on numerous evolving factors and future developments that it is not able to predict. Factors that could
adversely affect the Company’s financial statements related to the financial and operational impact of
COVID-19 are outlined in the "Risk Factors” section of this report.

Acquisition of JLT

On April 1, 2019, the Company completed the acquisition (the "Transaction") of all of the outstanding
shares of Jardine Lloyd Thompson Group plc ("JLT"), a public company organized under the laws of
England and Wales. In accordance with the terms of the Transaction, JLT shareholders received £19.15
in cash for each JLT share, which valued JLT’s existing share capital at approximately £4.3 billion (or
approximately $5.6 billion based on the exchange rate of U.S. $1.31:£1) on the Transaction closing date.
As of December 31, 2020, the Company has substantially integrated JLT into all of its business
operations.

After the acquisition of JLT, the Company assumed the legal liabilities of JLT’s litigation and regulatory
exposures as of April 1, 2019. Please see the "Risk Factors" section of this Annual Report on Form 10-K
for risks associated with the acquisition and Note 16 to the consolidated financial statements which
discusses certain errors and omission matters related to the acquisition.

JLT's results of operations for the period April 1, 2019 through December 31, 2019 are included in the
Company’s results of operations for 2019. In accordance with applicable accounting guidance, JLT's
results of operations for the period January 1 through March 31, 2019 and for the year ended 2018 are
not included in the Company's results of operations and therefore, affect comparability. The Company’s
results for the years ended December 31, 2020 and 2019 were impacted by JLT related acquisition,
restructuring and integration costs as well as legacy MMC restructuring programs as discussed in Note 14
to the consolidated financial statements.

Consolidated operating income was $3.1 billion in 2020 compared with $2.7 billion in 2019, reflecting the
impact of a 3% increase in revenue and an increase in expenses of 1%. On an underlying basis, revenue
increased 1%, reflecting an increase of 3% in Risk & Insurance Services offset by a decrease in
Consulting of 2%. On an underlying basis, expenses decreased 2%, reflecting a decrease in JLT

38

integration and restructuring and acquisition-related costs and savings realized from the completion of
integration efforts to date. The expense decrease also reflects lower travel and entertainment, meeting
costs and outside services resulting from the Company’s restrictions on travel and cost containment
measures taken in light of COVID-19 and lower expenses recoverable from clients. These decreases
were partly offset by higher incentive compensation, severance and a JLT legacy E&O provision of $161
million recorded in 2020, which is discussed in Note 16 of the consolidated financial statements.

Income before income taxes increased 14% to $2.8 billion as compared to $2.4 billion in 2019, reflecting
the change in operating income discussed in the preceding paragraph, partially offset by lower investment
income.

Diluted earnings per share increased 16% to $3.94 in 2020 compared with $3.41 in 2019. This increase is
a result of the factors discussed above, and a lower effective tax rate in 2020.

Risk and Insurance Services operating income increased $513 million, or 28%, in 2020 compared with
2019. Revenue increased 8%, reflecting increases of 3% on an underlying basis and 1% from
acquisitions, partly offset by a 1% decrease from the impact of foreign currency translation. Expense
increased 3% reflecting decreases of 2% on an underlying basis and 1% from the impact of foreign
currency translation, partly offset by an increase of 2% from acquisitions. The decrease in underlying
expenses is primarily due to lower JLT integration, restructuring and acquisition related costs and savings
realized from the completion of integration efforts to date. The decrease also reflects lower travel and
entertainment and meeting costs resulting from the Company’s restrictions on travel and cost containment
measures taken in light of COVID-19, partly offset by higher severance.

Consulting operating income decreased $216 million, or 18%, to $1.0 billion in 2020 compared with 2019,
reflecting the impact of a decrease in revenue of 2% and an increase in expense of 1%. Revenue
decreased 2% on an underlying basis and 1% from the impact of dispositions. On an underlying basis,
expense increased 1% primarily due to a JLT legacy E&O provision of $161 million recorded in 2020,
higher JLT integration and restructuring related costs as well as higher severance, partly offset by lower
travel, entertainment and meeting costs resulting from the Company’s restrictions on travel and cost
containment measures taken in light of COVID-19 and lower expenses recoverable from clients.

the following items:

•

•

•

•

•

•

Restructuring costs, excluding JLT: Includes severance, adjustments to restructuring liabilities
for future rent under non-cancellable leases and other real estate exit costs, and restructuring
costs related to the integration of recent acquisitions. These costs are discussed in more detail in
Note 14 of the consolidated financial statements.

JLT integration and restructuring costs: Includes severance, lease related exit costs as well
as consulting costs from the JLT Transaction. These costs are discussed in more detail in Note 14
of the consolidated financial statements.

JLT acquisition related costs: Includes advisor fees and stamp duty taxes related to the closing
of the JLT Transaction and retention costs. Also includes the loss on the sale of JLT's aerospace
business, which is included in revenue.

JLT legacy E&O provision: In 2020, reflects a provision for a legacy JLT E&O relating to
suitability of financial advice provided to individuals for defined benefit pension transfers. This
provision is discussed in more detail in Note 16 of the consolidated financial statements.

Change in fair value of acquisition related derivatives: In connection with the JLT Transaction,
to hedge the risk of appreciation of the GBP-denominated purchase price relative to the U.S.
dollar, in September 2018, the Company entered into a deal contingent foreign exchange contract
(the "FX Contract") to, solely upon consummation of the JLT Transaction, purchase £5.2 billion
and sell a corresponding amount of U.S. dollars at a contracted exchange rate. The FX Contract
is discussed in Note 11 to the consolidated financial statements. An unrealized loss of $325
million related to the fair value changes to this derivative was recognized in the consolidated
statement of income for the year ended December 31, 2018, largely due to the depreciation of the
GBP from September 2018. In 2019, the Company recorded a gain of $31 million upon final
settlement of the FX Contract.

In addition, to hedge the economic risk of increases in interest rates prior to its issuance of senior
notes in January 2019, in the fourth quarter of 2018, the Company entered into treasury lock
contracts related to $2 billion of the expected debt issuance. These economic hedges were not
designated as accounting hedges. The Company recorded an unrealized loss of $116 million
related to the changes in the fair value of these derivatives in the consolidated statement of
income for the year ended December 31, 2018. In January 2019, upon issuance of the $5 billion
of senior notes, the Company settled the treasury lock contracts and made a payment to its
counter party for $122 million.

JLT also had a number of foreign exchange contracts to hedge the risk of foreign exchange
movements between the U.S. dollar and the GBP, related to JLT’s U.S. dollar denominated
revenue in the U.K. Prior to the acquisition, these derivative contracts were designated as cash
flow hedges. Upon completion of the JLT Transaction, these derivative contracts were not re-
designated as cash flow hedges by the Company. The contracts were settled in June 2019. The
change in fair value between the acquisition date and the settlement date resulted in a charge of
$26 million for the year ended December 31, 2019. The charge is recorded as a change in fair
value of acquisition related derivative contracts in the consolidated statement of income.

JLT related interest income and expense: To secure funding for the Transaction, the Company
entered into a bridge loan agreement with aggregate commitments of £5.2 billion in September
2018. The Company paid the customary upfront fees related to the bridge loan, which were
amortized as interest expense based on the period of time the facility was expected to be in
effect. The Company recorded interest expense of approximately $30 million for the year ended
December 31, 2018 related to the amortization of the bridge loan fees and an additional $6 million
in 2019 upon termination of the bridge loan agreement in connection with the closing of the JLT
Transaction. The Company recorded approximately $47 million of interest expense related to the
senior notes issued in the first quarter of 2019 and $25 million of interest income from the
investment of the proceeds prior to the closing of the JLT Transaction.

Investment loss-Alexander Forbes ("AF"): The Company recorded an impairment charge of
$83 million in the 2018 consolidated statement of income for an other than temporary decline in
the value of the investment. During 2020, the Company sold approximately 242 million shares of
the common stock of AF. Upon completion of the sales of these shares, the investment in AF was
accounted at fair value, with investment gains and losses recorded as investment income (loss) in
the consolidated statement of income.

Pension settlement charge: The Defined Benefit Pension Plans in the U.K. and certain other
countries 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 in accordance with 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 in 2018 exceeded the settlement
thresholds in two of the U.K. plans. The Company recorded non-cash settlement charges,
primarily related to these plans of $42 million for the year ended December 31, 2018, of which
approximately 90% impacted Risk and Insurance Services. In 2020 and 2019, the Company
recorded $3 million and $7 million, respectively, of non-cash pension settlement charges related
to certain of its non U.S. plans.

JLT Integration and Restructuring Costs

The Company is completing its integration of JLT, which is discussed in more detail in Note 14 to the
consolidated financial statements. The costs incurred in connection with the integration and restructuring
of the combined businesses, primarily related to severance, real estate rationalization and technology,
consulting fees related to the management of the integration processes and legal fees related to the
rationalization of legal entity structures. The Company incurred costs of $251 million in 2020 and $335
million in 2019 and expects the remaining costs of $139 million to be incurred in 2021 of which $134
million will be cash expenditures. Through December 31, 2020, the Company has exceeded the initial
estimated savings of $350 million. The Company now expects approximately $425 million of annualized
savings when the integration is completed in 2021.

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 calculation of underlying revenue growth for the year ended December 31, 2020 as compared to
2019, is calculated as if MMC and JLT were a combined company as of January 1, 2019, but excludes the
impact of currency and other acquisitions, dispositions, and transfers among businesses. Combined prior
year revenue information for MMC and JLT for the year ended December 31, 2019 are presented below.
The unaudited 2019 JLT revenue amounts in the "2019 including JLT" column reflect historical JLT
revenue information following IFRS, adjusted to conform with U.S. GAAP and the Company's specific
accounting policies, primarily related to development of constraints and subsequent release of those
constraints related to the reinsurance business. The decrease in revenue due to the disposal of JLT's
Aerospace business is reflected in the acquisitions/dispositions column beginning in June 2019, when the
sale was completed. See the reconciliation of non-GAAP measures within MD&A. All other acquisitions/
dispositions activity is included in the acquisitions/dispositions column. Underlying expense growth is
calculated in a similar manner.

The impact of foreign currency exchange fluctuations, acquisitions and dispositions, including transfers
among businesses, on the Company’s operating revenues by segment are as follows:

Consolidated revenue was $17 billion in 2020, an increase of 3%, or 1% on an underlying basis. Revenue
in the Risk and Insurance Services segment increased 8% in 2020 compared with 2019, or 3% on an
underlying basis. Revenue increased 3% and 6% on an underlying basis at Marsh and Guy Carpenter,
respectively, as compared with 2019. The Consulting segment's revenue decreased 2% compared with
2019, as well as on an underlying basis. Revenue decreased 1% and 4% on an underlying basis at
Mercer and Oliver Wyman Group, respectively, as compared with 2019.

Operating Expense

Consolidated operating expenses increased 1% in 2020 compared with 2019. Expenses decreased 2%
on an underlying basis, reflecting a decrease in JLT integration and restructuring and acquisition-related
costs, and savings realized from the completion of integration efforts to date. The decrease also reflects
lower travel and entertainment, meeting costs and outside services resulting from the Company’s
restrictions on travel and cost containment measures taken in light of COVID-19 and lower expenses
recoverable from clients. These decreases were partly offset by a JLT legacy E&O provision of $161
million recorded in 2020, higher incentive compensation and severance.

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 and 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 and 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

43

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 8% in 2020 compared with 2019.
Revenue grew 3% on an underlying basis and 1% from the impact of acquisitions, partly offset by a 1%
decrease related to the impact of foreign currency translation.

In Marsh, revenue increased 3% on an underlying basis and 2% from the impact of acquisitions, partly
offset by a 1% decrease from the impact of foreign currency translation. U.S./Canada had underlying
revenue growth of 5%. International operations increased 1% on an underlying basis, reflecting increases
of 4% in Asia Pacific and 3% in Latin America, while EMEA was flat compared to prior year.

Guy Carpenter’s revenue increased 15% to $1.7 billion in 2020 compared with 2019, or 6% on an
underlying basis.

Fiduciary interest income was $46 million in 2020 compared with $105 million in 2019. The decrease in
2020 compared to 2019 reflects the impact of lower interest rates partially offset by a higher level of
average invested funds.

The Risk and Insurance Services segment completed seven acquisitions during 2020. Information
regarding those acquisitions is included in Note 5 to the consolidated financial statements.

Expense

Expense in the Risk and Insurance Services segment increased 3% in 2020 compared with 2019,
reflecting decreases of 2% on an underlying basis and 1% from the impact of foreign currency, partly
offset by a 2% increase from acquisitions. The decrease in underlying expense reflects lower JLT
integration, restructuring and acquisition related costs and savings realized from the completion of
integration efforts to date. The decrease also reflects lower travel and entertainment and meeting costs
resulting from the Company’s restrictions on travel and cost containment measures taken in light of
COVID-19 and lower base salaries. These decreases are partly offset by higher incentive compensation
and severance.

44

Consulting

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, wealth and career. 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, which is impacted by 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 2020 decreased 2% compared with 2019, reflecting decreases of 2% on an
underlying basis and 1% from the impact of dispositions.

Mercer's revenue in 2020 decreased 1% on an underlying basis and 2% from the impact of dispositions.
The decrease in underlying revenue reflects decreases in both Career of 8% and Wealth of 1% partly
offset by an increase in Health of 2%. Oliver Wyman Group’s revenue decreased 3% in 2020 compared
with 2019, or 4% on an underlying basis.

Expense

Consulting expense in 2020 increased 1% compared with 2019. This reflects an increase of 1% on an
underlying basis and a decrease of 1% from the impact of dispositions. The increase in underlying
expense reflects a JLT legacy E&O provision of $161 million recorded in 2020, higher JLT integration and
restructuring costs as well as higher base salaries, incentive compensation and severance. These
increases were partly offset by lower travel, entertainment and meeting costs resulting from the
Company’s restrictions on travel and cost containment measures taken in light of COVID-19 and lower
expenses recoverable from clients.

Corporate and Other

Corporate expense in 2020 was $274 million compared with $366 million in 2019. Expenses decreased
17% on an underlying basis due to lower acquisition, integration and restructuring costs primarily related

45

to the JLT Transaction and savings realized from the completion of integration efforts to date, partly offset
by higher base salaries.

Other Corporate Items

Interest

Interest income earned on corporate funds amounted to $7 million in 2020 compared with $39 million in
2019. During the first quarter of 2019, the Company issued approximately $6.5 billion of senior notes
related to the JLT acquisition. The funds were held in escrow and released for payment in April 2019,
when the acquisition was completed. The decrease in interest income from the prior year is primarily due
to interest earned on these funds in 2019. Interest expense in 2020 was $515 million compared with $524
million in 2019. The decrease in interest expense was primarily due to the impact of lower average
interest rates on borrowings.

Investment (Loss) Income

The caption "Investment (loss) income" in the consolidated statements of income comprises realized and
unrealized gains and losses from investments. It includes, when applicable, other than temporary declines
in the value of securities, mark-to-market increases or decreases in equity investments with readily
determinable fair values and equity method gains or losses on its investments in private equity funds. The
Company's investments may include direct investments in insurance, consulting or other strategically
linked companies and investments in private equity funds.

The Company recorded a net investment loss of $22 million in 2020, primarily due to the loss from the
sale of shares of AF during the second quarter of 2020. The Company recorded net investment income of
$22 million in 2019 which included gains of $10 million related to mark-to-market changes to equity
securities and gains of $12 million related to investments in private equity funds and other investments.

Income Taxes

The Company completed the JLT Transaction on April 1, 2019. During 2020, the integration of this global
organization required intercompany transfers of acquired entities into the Company's country structures
and the combination of those entities within the equivalent Company businesses. The integration
transactions were designed to be tax efficient. The Company's global effective tax rate on JLT's earnings
was reduced compared to JLT's pre-acquisition tax rate by utilizing debt for the restructuring transactions
to be capital efficient, and reducing the generation of post-acquisition tax losses by merging historically
unprofitable JLT entities with profitable Company operations. Provisions for deferred taxes and uncertain
tax positions were established as part of the purchase price allocation as of April 1, 2019.

The broader JLT organization is now held under the Company's legal entity structure, which makes it part
of a U.S.-based multinational company and subjects it to full U.S. taxation.

The Company's consolidated effective tax rate was 26.7%, 27.3%, and 25.6% in 2020, 2019, and 2018,
respectively. The rates in all periods reflect the effects of tax planning and the ongoing impact of the Tax
Cuts and Jobs Act ("TCJA"), including regulatory and other guidance as it became available. The tax rate
in 2020 includes a valuation allowance for certain tax credits, the impact of uncertain tax positions, and
certain tax planning benefits. The 2019 rate reflects items related to the JLT acquisition, including non-
deductible goodwill allocated to the sale of Aerospace and non-deductible expenses incurred in relation to
the JLT acquisition. The 2018 rate includes the effect of a charge related to the Company’s investment in
AF as discussed in Note 1. The tax rates in all periods reflect the impact of discrete tax matters, tax
legislation, and nontaxable adjustments to contingent acquisition consideration.

The effective tax rate may vary significantly from period to period for the foreseeable future. The effective
tax rate is sensitive to the geographic mix and repatriation of the Company's earnings, which may result in
higher or lower tax rates. A shift in the mix of profits among jurisdictions can also affect the effective tax
rate. In 2020, pre-tax income in Barbados, Canada, Ireland, Australia, Japan and Germany accounted for
approximately 60% of the Company's total non-U.S. pre-tax income, with effective rates in those countries
of 1%, 27%, 15%, 23%, 33.7%, and 32% respectively.

In addition, 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 value of associated
deferred tax assets which can be realized. A valuation allowance was recorded to reduce deferred tax

46

assets to the amount that the Company believes is more likely than not to be realized. Details are
provided in Note 7 of the consolidated financial statements. 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.

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 effective tax rate.

As a U.S. domiciled parent holding company, the Company is the issuer of essentially all of the
Company's external indebtedness, and incurs the related interest expense in the U.S. The Company’s
interest expense deductions are not currently limited. Further, most senior executive and oversight
functions are conducted in the U.S. and the associated costs are incurred primarily in the U.S. Some of
these expenses may not be deductible in the U.S., which may impact the effective tax rate.

The quasi-territorial tax regime provides an opportunity for the Company to repatriate foreign earnings
more tax efficiently and there is less incentive for permanent reinvestment of these earnings. However,
permanent reinvestment continues to be a component of the Company’s global capital strategy. The
Company continues to evaluate its global investment and repatriation strategy in light of our capital
requirements and potential costs of repatriation.

The Coronavirus Aid, Relief and Economic Security Act (the "CARES Act") was signed into law on March
27, 2020. The CARES Act provided over $2 trillion in economic relief to individuals, governmental
agencies and companies, to deal with the public health and economic impacts of COVID-19. Pursuant to
the CARES Act, payroll taxes due from March 27, 2020 through December 31, 2020 will be deferred until
2021 and 2022 (50% to be paid each year) without interest or penalties.

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 can also provide 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 in financing cash flows.

The Company derives a significant portion of its revenue and operating profit from operating subsidiaries
located outside of the U.S. Funds from those operating subsidiaries are regularly repatriated to the U.S.
out of annual earnings. At December 31, 2020, the Company had approximately $789 million of cash and
cash equivalents in its foreign operations, which includes $249 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 available funds from its non-U.S. operating
subsidiaries out of current annual earnings. Where appropriate, a portion of the current year earnings will
continue to be permanently reinvested. With respect to repatriating 2018 and prior earnings, the Company
has evaluated 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. In general, the Company has
determined that its permanent reinvestment assertions, in light of the enactment of the TCJA, should
allow the Company to repatriate previously taxed earnings from the deemed repatriations as cash
becomes available.

During 2020, the Company recorded foreign currency translation adjustments which increased net equity
by $559 million. Continued weakening of the U.S. dollar against foreign currencies would further 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. Conversely, strengthening of
the U.S. dollar against foreign currencies would decrease 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

47

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 $3.4 billion of cash from operations in 2020 and $2.4 billion in 2019. 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 2020, the Company contributed $65 million to its U.S. pension plans and $78 million to non-U.S.
pension plans compared to contributions of $35 million to U.S. plans and $87 million to non-U.S. plans in
2019.

In the U.S., 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 in
accordance with the ERISA guidelines. In 2020, the Company made $30 million of contributions to non-
qualified plans and $35 million to its qualified plans. The Company expects to contribute approximately
$37 million to its U.S. pension plans in 2021, including $7 million to the U.S. qualified plans to meet
ERISA funding requirements and $30 million to its non-qualified plans.

The Company contributed $34 million to its U.K. plans in 2020, including an expense allowance of
approximately $5 million. The Company's contributions to its U.K. plans in 2021 are expected to be
approximately $47 million, including an expense allowance of $16 million.

Outside the U.S., 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,
2020. 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 compared to U.S. GAAP
and may result in contributions irrespective of the U.S. GAAP funded status. For the MMC U.K. Pension
Fund, a new agreement was reached with the trustee in the fourth quarter of 2019 based on the surplus
funding position at December 31, 2018. In accordance with the agreement, no deficit funding is required
until 2023. The funding level will be re-assessed during 2022 to determine if contributions are required in
2023. In order to have greater influence over asset allocation and overall investment decisions, in
November 2019, 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 addition, in the U.K., the Company assumed responsibility for JLT's Pension Scheme ("JLT U.K. plan").
We currently expect to pay $29 million of deficit funding in 2021, although we will also reach a new
funding agreement with the trustee during 2021.

In the aggregate, the Company expects to contribute approximately $87 million to its non-U.S. defined
benefit plans in 2021, comprising approximately $40 million to plans outside of the U.K. and $47 million to
the U.K. plans.

Changes to Pension Plans

As part of the JLT Transaction, the Company assumed responsibility for a number of pension plans
throughout the world, the most significant of which is the JLT U.K. plan. The JLT U.K. plan has a defined
benefit section which was frozen to future accrual in 2006 and a defined contribution section. The assets
of the scheme are held in a trustee administered fund separate from the Company.

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

48

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 $2.4 billion and $3.5 billion at December 31, 2020 for the U.S. plans and non-
U.S. plans, respectively, compared with losses of $2.1 billion and $3.1 billion at December 31, 2019. The
increases in both the U.S. and non-U.S. plans was primarily due to a decrease in the discount rate used
to measure plan liabilities partly offset by an increase in asset values. 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 in
2020 and 2019 decreased in the U.S. and U.K. (the Company's largest plans) following increases in the
U.S. and the U.K. in 2018. 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 2020, the Company's defined benefit pension plan assets
had gains of 13.1% and 12.0% in the U.S. and U.K., respectively, as compared to gains of 21.4% and
13.1% in the U.S. and U.K., respectively, in 2019. During 2018, the Company's defined benefit pension
plan assets had losses of 7.4% in the U.S. and 1.0% in the U.K.

Overall, based on the measurement at December 31, 2020, total benefit credits related to the Company’s
defined benefit plans are expected to increase in 2021 by approximately $22 million compared to 2020,
reflecting an increase in non-U.S. plans of approximately $31 million, offset by a decrease in U.S. plans of
$9 million.

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 8 to the
consolidated financial statements.

Financing Cash Flows

Net cash used for financing activities was $1.9 billion in 2020 compared with $3.3 billion provided by
financing activities in 2019.

Credit Facilities

The Company and certain of its foreign subsidiaries have a multi-currency five-year unsecured revolving
credit facility of $1.8 billion. 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 October 2023 and requires the Company
to maintain certain coverage and leverage ratios which are tested quarterly. The Company borrowed $1
billion under this facility in the first quarter of 2020, which was repaid in full during the second quarter of
2020. There were no borrowings outstanding under this facility at December 31, 2020.

In January 2020, the Company entered into two new term loan facilities: a $500 million one-year facility
and a $500 million two-year facility. In the first quarter of 2020, the Company borrowed $1 billion against
these facilities. During the third quarter of 2020, the Company repaid $500 million of borrowings from its
one-year facility. In December 2020, the Company repaid $500 million of borrowings from the two year
facility. These two facilities were terminated as of December 31, 2020 after repayment of the initial draw
down.

In April 2020, the Company entered into a new 364 day $1 billion unsecured revolving credit facility with a
term out option after one year. The facility has similar coverage and leverage ratios as the multi-currency
five-year unsecured revolving credit facility. The Company had no borrowings outstanding under this
facility at December 31, 2020.

The Company also maintains other credit facilities, guarantees and letters of credit with various banks,
aggregating $573 million at December 31, 2020 and $598 million at December 31, 2019. There were no
outstanding borrowings under these facilities as of December 31, 2020 or as of December 31, 2019.

Debt

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 were used for
general corporate purposes. The Company had no commercial paper outstanding at December 31, 2020.

49

In December 2020, the Company repaid $700 million of maturing Senior Notes and $300 million of
floating rate notes with an original maturity of December 2021.

In May 2020, the Company issued $750 million of 2.250% Senior Notes due 2030. The Company used
the net proceeds from this offering to pay outstanding borrowings under the revolving credit facility.

In March 2020, the Company repaid $500 million of maturing Senior Notes.

In September 2019, the Company repaid $300 million of maturing Senior Notes.

During 2019, the Company issued approximately $6.5 billion of Senior Notes to primarily fund the
acquisition of JLT, including the payment of related fees and expenses, and to repay certain JLT
indebtedness, as well as for general corporate purposes.

In connection with the closing of the JLT Transaction, the Company assumed approximately $1 billion of
historical JLT indebtedness, which it repaid during 2019. The Company incurred debt extinguishment
costs of $32 million in regard to the repayment of this debt.

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 with S&P and a Negative outlook with Moody's.

Share Repurchases

The Company did not repurchase any shares of its common stock during 2020. In November 2019, 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. As of December 31, 2020, the Company remained authorized to purchase shares of its
common stock up to a value of approximately $2.4 billion. There is no time limit on this authorization.

During 2019, the Company repurchased 4.8 million shares of its common stock for total consideration of
$485 million at an average price per share of $100.48.

Dividends

The Company paid total dividends of $943 million in 2020 ($1.84 per share), $890 million in 2019 ($1.74
per share) and $807 million in 2018 ($1.58 per share).

Contingent Payments Related To Acquisitions

During 2020, the Company paid $102 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 $54 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 $48 million are reflected as
operating cash flows. Remaining estimated future contingent consideration payments of $243 million for
acquisitions completed in 2020 and in prior years are included in accounts payable and accrued liabilities
or other liabilities in the consolidated balance sheet at December 31, 2020. The Company paid deferred
purchase consideration related to prior years' acquisitions of $68 million and $43 million for the years
ended December 31, 2020 and 2019, respectively, that is reflected as financing cash flows. Remaining
deferred cash payments of approximately $241 million are included in accounts payable and accrued
liabilities or other liabilities in the consolidated balance sheet at December 31, 2020.

In 2019, the Company paid $63 million of contingent payments related to acquisitions made in prior
periods, of which $22 million was reported as financing cash flows and $41 million as operating cash
flows.

Derivatives

Net Investment Hedge

The Company has investments in various subsidiaries with Euro functional currencies. As a result, the
Company is exposed to the risk of fluctuations between the Euro and U.S. dollar exchange rates. As part
of its risk management program to fund the JLT acquisition, the Company issued €1.1 billion Senior
Notes, and designated the debt instruments as a net investment hedge of its Euro denominated
subsidiaries. The hedge is re-assessed each quarter to confirm that the designated equity balance at the

50

beginning of each period continues to equal or exceed 80% of the outstanding balance of the Euro debt
instrument and that all the critical terms of the hedging instrument and the hedged net investment
continue to match. If the hedge is highly effective, the change in the debt balance related to foreign
exchange fluctuations will be recorded in foreign currency translation gains (losses) in the consolidated
balance sheet. The U.S. dollar value of the Euro notes increased by $124 million during 2020 related to
the change in foreign exchange rates. The Company concluded that the hedge was highly effective and
recorded an increase to accumulated other comprehensive loss for the year ended December 31, 2020.

JLT Fair Value Debt Derivative Contracts

Prior to the JLT Transaction closing, a significant portion of JLT's outstanding senior notes were
denominated in U.S. dollars. In order to hedge its exposure against the risk of fluctuations between the
British Pound ("GBP") and the U.S. dollar, JLT entered into foreign exchange and interest rate swaps,
which were designated as fair value hedges. In June 2019, the Company redeemed these U.S. dollar
denominated senior notes and settled the related derivative contracts. Both the change in fair value of the
debt and the change in fair value of the derivative contracts were recorded in the consolidated statement
of income in the second quarter of 2019. The Company received approximately $112 million upon
settlement of these derivative contracts.

JLT Cash Flow Hedges

JLT also had a number of foreign exchange contracts to hedge the risk of foreign exchange movements
between the U.S. dollar and the GBP, related to JLT’s U.S. dollar denominated revenue in the U.K. Prior
to the acquisition, these derivative contracts were designated as cash flow hedges. Upon acquisition, the
derivative contracts were not re-designated as cash flow hedges by the Company. The contracts were
settled in June 2019. The change in fair value between the acquisition date and the settlement date
resulted in a charge of $26 million in the second quarter of 2019. The charge is recorded as a change in
fair value of acquisition related derivative contracts in the consolidated statement of income.

Foreign Exchange Forward Contract

In connection with the JLT Transaction, to hedge the risk of appreciation of the GBP-denominated
purchase price relative to the U.S. dollar, on September 20, 2018, the Company entered into the FX
Contract to, solely upon consummation of the Transaction, purchase £5.2 billion and sell a corresponding
amount of U.S. dollars at a contracted exchange rate. The FX Contract, which did not qualify for hedge
accounting treatment under applicable accounting guidance, is discussed in Note 11 to the consolidated
financial statements. The Company settled the FX Contract on April 1, 2019, recording a realized gain to
the consolidated statement of income of approximately $31 million in 2019. The cash outflow related to
the settlement of the FX Contract was approximately $294 million in 2019.

Foreign Exchange Contract on Euro Debt Issuance

In March 2019, the Company issued €1.1 billion of senior notes related to the JLT Transaction. See Note
13 for additional information related to the Euro senior note issuances. In connection with the senior note
issuances of €1.1 billion, the Company entered into a forward exchange contract to hedge the economic
risk of changes in foreign exchange rates from the issuance date to settlement date of the Euro senior
notes. This forward exchange contract was settled in March 2019 and the Company recorded a charge of
$7 million in the first quarter of 2019 related to the settlement of this contract.

Treasury Locks on Senior Notes

In connection with the JLT Transaction and to hedge the risk of increases in future interest rates prior to
its issuance of senior notes, the Company entered into treasury locks related to $2 billion of the expected
debt in the fourth quarter of 2018. The fair value at December 31, 2018 was based on the published
treasury rate plus forward premium as of December 31, 2018 compared to the all in rate at the inception
of the contract. The contracts were not designated as an accounting hedge. The Company recorded an
unrealized loss of $116 million related to the change in the fair value of these derivatives in the
consolidated statement of income for the year ended December 31, 2018. In January 2019, upon
issuance of the $5 billion of senior notes, the Company settled the treasury lock derivatives and made a
payment to its counter party for $122 million.

51

Investing Cash Flows

Net cash used for investing activities amounted to $814 million in 2020 compared with $5.7 billion used
for investing activities in 2019.

The Company paid $668 million and $5.5 billion, net of cash acquired, for acquisitions it made during
2020 and 2019, respectively.

During 2020, the Company sold certain businesses primarily in the U.S., U.K. and Canada for cash
proceeds of approximately $98 million.

At December 31, 2019, the Company owned approximately 443 million shares of the common stock of
AF, a South African company listed on the Johannesburg Stock Exchange, which was accounted for
under the equity method of accounting. In February 2020, the Company sold approximately 49 million
shares, and in May 2020, sold an additional 193 million shares, leaving the Company with an investment
of approximately 201 million shares of the common stock of AF at December 31, 2020. Upon completion
of the sale of shares in May 2020, the investment in AF was accounted at fair value, with investment
gains and losses recorded as investment income in the consolidated statement of income.

During the first quarter of 2019, the Company disposed of its investment in Benefitfocus for total proceeds
of approximately $132 million. The Company received $115 million in the first quarter of 2019 and $17
million in the second quarter of 2019 as final settlement on the sale.

During the second quarter of 2019, the Company disposed of its investment in Payscale and received
proceeds of approximately $47 million. In January 2019, the Company increased its equity ownership in
Marsh India from 26% to 49% for approximately $88 million. Marsh India is carried under the equity
method.

The Company’s additions to fixed assets and capitalized software, which amounted to $348 million in
2020 and $421 million in 2019, primarily related 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 $46 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 $98 million as the Company is
unable to reasonably predict the timing of settlement of these liabilities, other than approximately $20
million that may become payable during 2021.

The above does not include the remaining transitional tax payments related to the TCJA of $64.5 million.

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

52

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.

Revenue Recognition

In the Risk and Insurance Services segment, judgments related to the amount of variable revenue
consideration to ultimately be received on placement of quota share reinsurance treaties and contingent
commission from insurers, which was previously recognized when the contingency was resolved, now
requires significant judgments and estimates.

The Company capitalizes the incremental costs to obtain contracts primarily related to commissions or
sales bonus payments. These deferred costs are amortized over the expected life of the underlying
customer relationships. The Company also capitalizes certain pre-placement costs that are considered
fulfillment costs that are amortized at a point in time when the associated revenue is recognized.

Management also makes significant judgments and estimates to measure the progress toward completing
performance obligations and realization rates for consideration related to contracts as well as potential
performance-based fees in the Consulting segment.

See Note 2 to the consolidated financial statements for additional information.

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, 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.

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, 10 percent of the greater of the projected benefit obligation or the market-related value of plan
assets, 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

53

disclosed in Note 8 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 the end of 2020, the actual allocation for the U.S. plans was 64% equities and equity
alternatives and 36% fixed income. The target asset allocation for the U.K. plans, which comprise
approximately 81% of non-U.S. plan assets, is 32% equities and equity alternatives and 68% fixed
income. At the end of 2020, the actual allocation for the U.K. plans was 33% equities and equity
alternatives and 67% fixed income.

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 table below shows the weighted average assumed rate of return and the discount rate at the
December 31, 2020 measurement date (for measuring pension expense in 2021) 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. In addition, the assumed return on plan assets
would likely be impacted by changes in the interest rate environment and other factors, including equity
valuations, since these factors reflect the starting point used in the Company’s projection models. For
example, a reduction in interest rates may result in a reduction in the assumed return on plan 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
8 to the consolidated financial statements.

Income Taxes

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:

•

•

First, 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. 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, 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. The Company’s accounting policy follows the portfolio approach that leaves stranded income
tax effects in AOCI.

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 non-deductible expenses, 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
carry back 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 assessment for each of its reporting units
during the third quarter of each year. In accordance with applicable accounting guidance, a company can
assess qualitative factors to determine whether it is necessary to perform a quantitative goodwill
impairment test. Alternatively, the Company may elect to proceed directly to the quantitative goodwill

55

impairment test. In 2020, the Company elected to perform a qualitative impairment assessment. As part of
its assessment, the Company considered numerous factors, including:

•

•

that the fair value of each reporting unit exceeds its carrying value by a substantial margin based
on its most recent quantitative assessment in 2019;

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 2020 and concluded that a
quantitative goodwill impairment test was not required in 2020 and that goodwill was not impaired.

Share-Based Payment

The accounting guidance for share-based payments requires, among other things, that the estimated
grant date 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, 2020, there was $17.5 million of unrecognized compensation cost related to stock
option awards. The weighted-average period over which the costs are expected to be recognized is 1.23
years. Also as of December 31, 2020, there was $347.7 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 year.

See Note 9 to the consolidated financial statements for additional information regarding accounting for
share-based payments.

Investments and Derivatives

Although not directly recorded in the Company’s consolidated balance sheets, the Company's defined
benefit pension plans hold investments of approximately $19.1 billion, which include private equity and
other non-liquid investments. The fair value of the plan investments determines, in part, the over-or under-
funded status of those plans, which is included in the Company’s consolidated balance sheets. The
Company also has minority positions in certain equity securities (primarily Alexander Forbes), which are
accounted for at fair value with gains or losses recorded as investment gains or losses in the consolidated
statement of income. The Company also has approximately $111 million of investments in private equity
funds accounted for using the equity method of accounting.

The Company reviews the carrying value of its investments (both direct and held through its pension
plans) to determine if any valuation adjustments are appropriate under the applicable accounting
pronouncements. The Company bases its review on the facts and circumstances as they relate to each
investment. In those instances where quoted market prices are not available, particularly for private equity
funds, significant management judgment is required to determine the appropriate value of the Company’s
investments. Fair value of investments in private equity funds is determined by the funds’ investment
managers. Factors considered in determining the fair value of private equity investments include: implied
valuation of recently completed financing rounds that included sophisticated outside investors;
performance multiples of comparable public companies; restrictions on the sale or disposal of the
investments; trading characteristics of the securities; and the relative size of the holdings in comparison to
other private investors and the public market float.

In connection with the JLT Transaction, the Company entered into several derivative contracts, described
in Note 11 to the consolidated financial statements. These derivative contracts are recorded at fair value
at the end of each period, with the change in fair value recorded in the consolidated statements of

56

income. Prior to their settlement, determination of the fair value of these contracts, in particular the deal
contingent foreign exchange contract, required significant management judgments or estimates about the
potential closing dates of the transaction and remaining value of the deal contingency feature. All
derivative contracts related to the JLT Transaction were settled during 2019.

Purchase Price Allocation

Assets acquired and liabilities assumed, including contingent consideration, as part of a business
acquisition are generally recorded at their fair value at the date of acquisition. The excess of purchase
price over the fair value of assets acquired and liabilities assumed is recorded as goodwill. Determining
fair value of identifiable assets, particularly intangibles, and liabilities acquired also requires management
to make estimates, which are based on all available information and in some cases assumptions with
respect to the timing and amount of future revenues and expenses associated with an asset. These
estimates directly impact the amount of identified intangible assets recognized and the related
amortization expense in future periods.

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".

Reconciliation of Non-GAAP Measures

On April 1, 2019, the Company completed its acquisition of JLT. JLT's results of operations for the year
ended December 31, 2020 are included in the Company’s results of operations. JLT's results of
operations for the three months ending March 31, 2019 are not included in the Company's results of
operations for the twelve month period ended December 31, 2019. Prior to being acquired by the
Company, JLT operated in three segments, Specialty, Reinsurance and Employee Benefits. As of April 1,
2019, the historical JLT businesses were combined into MMC operations as follows: JLT Specialty is
included by geography within Marsh, JLT Reinsurance is included within Guy Carpenter and the majority
of the JLT Employee Benefits business is included in Mercer Health and Wealth.

The JLT Transaction had a significant impact on the Company’s results of operations in 2020. The
Company believes that in addition to the change in reported GAAP revenue, a comparison of 2020 GAAP
reported revenue to the combined 2019 revenue of MMC and JLT, as if the companies were combined on
January 1, 2019, provides investors with meaningful information as to the Company’s year-over-year
underlying operating results. Investors should not consider the comparison of these non-GAAP measures
in isolation from, or as a substitute for, the financial information that the Company reports in accordance
with GAAP.

The "2019 Including JLT" revenue information set forth in the table below presents revenue information as
if the companies were combined on January 1, 2019 and is not necessarily indicative of what the results
would have been had we operated the business since January 1, 2019.

The MMC revenue amounts are as previously reported by the Company in its annual filing of Form 10-K
for the year ended December 31, 2019. JLT 2019 revenue information is derived using the same policies
and adjustments as the "JLT Supplemental Information - Revenue Analysis" furnished to the SEC on June
6, 2019 on Form 8-K, which is not incorporated by reference in this Form 10-K, and includes the revenue
from JLT’s aerospace business.

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, 2020

$

$

2,089

8,585

Based on the above balances, if short-term interest rates increased or decreased by 10%, or 3 basis
points, over the full year, annual interest income, including interest earned on fiduciary funds, would
increase or decrease by approximately $2 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 53% 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 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
2020, the Company estimates net operating income would increase or decrease by approximately $39
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,
including investments of approximately $72 million that are valued using readily determinable fair values
and approximately $33 million of investments without readily determinable fair values. The Company also
has investments of approximately $280 million that are accounted for using the equity method. The
investments are subject to risk of decline in market value, which, if determined to be other than temporary
for assets without readily determinable fair values, could result in realized impairment losses. The

59

Company periodically reviews the carrying value of such investments to determine if any valuation
adjustments are appropriate under the applicable accounting pronouncements.

At December 31, 2020, the Company owns approximately 14% of the common stock of AF, a South
African company listed on the Johannesburg Stock Exchange. The investment in AF is accounted at fair
value, with unrealized gains and losses recorded as investment income in the consolidated statement of
income. The fair value of this investment at December 31, 2020 was approximately $54 million.

Business Update Related To COVID-19

In March 2020, the World Health Organization declared the Coronavirus (COVID-19) a pandemic. The
pandemic has impacted essentially every geography in which the Company operates. Governments
implemented various restrictions around the world, including closure of non-essential businesses, travel,
shelter-in-place requirements for citizens and other restrictions. The Company has taken a number of
precautionary steps to safeguard its businesses and colleagues from COVID-19, including implementing
travel restrictions, arranging work from home capabilities and flexible work policies. In the second and
third quarters of 2020, the Company began re-opening offices in various locations around the world, while
ensuring that it continued to adhere to guidelines and orders issued by national, state and local
governments. The timing of additional office re-openings will vary based on the conditions and restrictions
in each location. In the fourth quarter, there was a surge in COVID-19 infections in many parts of the
world, leading to renewed lock-downs and increased government restrictions. The safety and well-being
of our colleagues continues to be our first priority. Several vaccines have been or are in various stages of
approval. However, the speed of distribution and the impact on colleagues' ability to return to the office
remains uncertain. The vast majority of the Company’s colleagues have continued and will continue
working in a remote work environment for most of 2021. The Company expects it will continue its ability to
service clients effectively while colleagues remain in a remote work environment.

For the year ended December 31, 2020, the COVID-19 pandemic had an adverse impact on the
Company’s revenue growth, primarily in our businesses that are discretionary in nature, which was partly
mitigated through disciplined expense management by implementing restrictions on travel and other cost
containment measures. However, the ultimate extent of the COVID-19 impact to the Company will depend
on numerous evolving factors and future developments that it is not able to predict.

On April 1, 2019, the Company completed the acquisition (the "Transaction") of all of the outstanding
shares of Jardine Lloyd Thompson Group plc ("JLT"), a public company organized under the laws of
England and Wales. JLT's results of operations for the period April 1, 2019 through December 31, 2019
are included in the Company’s results of operations for 2019. JLT's results of operations for the period
January 1 through March 31, 2019 and for the year ended 2018 are not included in the Company's results
of operations and therefore, affect comparability. Prior to being acquired by the Company, JLT operated in
three segments: Specialty, Reinsurance and Employee Benefits. JLT operated in 41 countries, with
significant revenue in the United Kingdom, Pacific, Asia and the United States. As of April 1, 2019, the
historical JLT businesses were combined into MMC operations as follows: JLT Specialty is included by
geography within Marsh, JLT Reinsurance is included in Guy Carpenter and the majority of JLT's
Employee Benefits business is included in Mercer Health and Wealth. As of December 31, 2020, the
Company has substantially integrated JLT into all of its business operations.

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.

66

Revenue: The Company provides detailed discussion regarding its revenue policies in Note 2 to the
consolidated financial statements.

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, 2020, the Company
maintained $270 million related to these regulatory requirements.

Fixed Assets: Fixed assets are stated at cost less accumulated depreciation and amortization.
Expenditures for improvements are capitalized. Upon sale or retirement of an asset, the cost and related
accumulated depreciation and amortization are removed from the accounts and any gain or loss is
reflected in income. Expenditures for maintenance and repairs are charged to operations as incurred.

Depreciation of buildings, building improvements, furniture, and equipment is provided on a straight-line
basis over the estimated useful lives of these assets. Furniture and equipment is depreciated over periods
ranging from three to ten years. Leasehold improvements are amortized on a straight-line basis over the
periods covered by the applicable leases or the estimated useful life of the improvement, whichever is
less. Buildings are depreciated over periods ranging from thirty to forty years. The Company periodically
reviews long-lived assets for impairment whenever events or changes indicate that the carrying value of
assets may not be recoverable.

The components of fixed assets are as follows:

December 31,
(In millions of dollars)
Furniture and equipment
Land and buildings
Leasehold and building improvements

Investments: The caption "Investment (loss) income" in the consolidated statements of income
comprises realized and unrealized gains and losses from investments recognized in earnings. It includes,
when applicable, other than temporary declines in the value of securities, mark-to-market increases or
decreases in equity investments with readily determinable fair values and equity method gains or losses
on the Company's investments in private equity funds.

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.

In 2020, the Company recorded an investment loss of $22 million compared to investment income of $22
million in 2019 and investment loss of $12 million in 2018. The net investment loss in 2020 is primarily
due to the $23 million loss from the sale of shares of AF during the second quarter of 2020. The
investment gain in 2019 includes gains of $10 million related to mark-to-market changes in equity
securities and gains of $12 million related to investments in private equity funds and other investments.
The investment loss in 2018 includes an impairment charge of $83 million related to its investment in AF.
The net investment loss in 2018 also includes gains of $54 million related to mark-to-market changes in
equity securities and gains of $17 million related to investments in private equity funds and other
investments.

67

Goodwill and Other Intangible Assets: Goodwill represents acquisition costs in excess of the fair value
of net assets acquired. Goodwill is assessed 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. In accordance
with applicable accounting guidance, a company can assess qualitative factors to determine whether it is
necessary to perform a goodwill impairment test. Alternatively, a company may elect to proceed directly to
the quantitative goodwill impairment test. When a quantitative 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 6, the Company elected to perform a qualitative impairment assessment
during 2020. 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 assessed 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, 2020 and 2019.

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 $481 million and $496 million, net of
accumulated amortization of $1.6 billion and $1.4 billion as of December 31, 2020 and 2019, 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, a
subsidiary of the Company, and other methods to estimate potential losses, including estimated legal
costs. 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.

As of December 31, 2020, the Company’s liability for errors and omissions was $639 million, compared to
$484 million at December 31, 2019, of which $271 million and $149 million, respectively, were included in
accounts payable and accrued liabilities in the Consolidated Balance Sheets.

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.

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

68

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 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.

Integration and Restructuring Charges: Severance and related costs are recognized based on
amounts due under established severance plans or estimates of one-time benefits that will be provided.
Typically, severance benefits are recognized when the impacted colleagues are notified of their expected
termination and such termination is expected to occur within the legally required notification period. These
costs are included in compensation and benefits in the consolidated statements of income.

Costs for real estate consolidation are recognized based on the type of cost, and the expected future use
of the facility. For locations where the Company does not expect to sub-lease the property, the
amortization of any right-of-use asset is accelerated from the decision date to the cease use date. For
locations where the Company expects to sub-lease the properties subsequent to its vacating the property,
the right-of-use asset is reviewed for potential impairment at the earlier of the cease use date or the date
a sub-lease is signed. To determine the amount of impairment, the fair value of the right-of-use asset is
determined based on the present value of the estimated net cash flows related to the property.
Contractual costs outside of the right-of-use asset are recognized based on the net present value of
expected future cash outflows for which the Company will not receive any benefit. Such amounts are
reliant on estimates of future sub-lease income to be received and future contractual costs to be incurred.

These costs are included in other operating expenses in the consolidated statements of income.

Other costs related to integration and restructuring, such as moving, legal or consulting costs are
recognized as incurred. These costs are included in other operating expenses in the consolidated
statements of income.

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. 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. If a derivative is not designated as an accounting hedge, the change in fair value
is recorded in earnings.

69

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 is calculated by dividing the
after-tax income attributable to the Company by the weighted average number of outstanding shares of
the Company’s common stock.

Diluted net income per share attributable to the Company is calculated by dividing the after-tax income
attributable to the Company 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.

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 $46 million,
$105 million and $65 million in 2020, 2019 and 2018, respectively. The Consulting segment recorded
fiduciary interest income of $1 million, $4 million and $3 million in 2020, 2019 and 2018, 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 $11.2 billion and $8.9 billion at
December 31, 2020 and 2019, 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 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.

Estimates: The preparation of the consolidated financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of
assets and liabilities at the date of the financial statements, and the reported amounts of revenue and
expense during the reporting period. On an ongoing basis, the Company evaluates its estimates,
judgments and methodologies. The estimates are based on historical experience and on various other
assumptions that the Company believes are reasonable. Such matters include:

70

•

•

•

•

•

•

•

•

•

the allowance for current expected credit losses on receivables,

estimates of revenue,

impairment assessments and charges,

recoverability of long-lived assets,

liabilities for errors and omissions,

deferred tax assets, uncertain tax positions and income tax expense,

share-based and incentive compensation expense,

useful lives assigned to long-lived assets, and depreciation and amortization,

fair value estimates of contingent consideration receivable or payable related to acquisitions
or dispositions

The Company believes these estimates are reasonable based on information currently available at the
time they are made. In most situations where estimates, fair values or recoverability of assets is
dependent upon short or long term projections of cash flows, revenues or earnings before interest, taxes,
depreciation and amortization ("EBITDA"), the Company has based its projections assuming the gradual
lifting of global lockdowns during 2021. The Company has also considered potential impacts to its
customer base in various industries and geographies. The ultimate extent to which the COVID-19
pandemic will directly or indirectly impact the Company’s businesses, results of operations and financial
condition will depend on future developments that are highly uncertain, including new information that
may emerge concerning COVID-19 and the actions taken to contain it or treat it, and the economic impact
on local, regional, national and international customers and markets. Actual results may differ from these
estimates.

New Accounting Pronouncements Adopted Effective January 1, 2021

In January 2020, the FASB issued guidance that addresses accounting for the transition into and out of
the equity method and measuring certain purchased options and forward contract to acquire investments.
The standard takes effect for public business entities for fiscal years, and interim periods within those
fiscal years, beginning after December 15, 2020. The adoption of this standard did not have a material
impact on the Company’s financial position or its results of operations.

In December 2019, the FASB issued guidance related to the accounting for income taxes. The standard
removes specific exceptions in the current rules and eliminates the need for an organization to analyze
whether the following apply in a given period: (a) exception to the incremental approach for intraperiod tax
allocation; (b) exceptions to accounting for basis differences when there are ownership changes in foreign
investments and (c) exception in interim period income tax accounting for year-to-date losses that exceed
anticipated losses. The standard also is designed to improve financial statement preparers’ application of
income tax-related guidance and simplify GAAP for (a) franchise taxes that are partially based on income;
(b) transactions with a government that result in a step-up in the tax basis of goodwill; (c) separate
financial statements of legal entities that are not subject to tax and (d) enacted changes in tax laws in
interim periods. The standard takes effect for public business entities for fiscal years, and interim periods
within those fiscal years, beginning after December 15, 2020. The adoption of this standard did not have
a material impact on the Company’s financial position or its results of operations.

New Accounting Pronouncements Adopted Effective January 1, 2020:

In August 2018, the FASB issued new guidance that amends required fair value measurement
disclosures. The guidance adds new requirements, eliminates some current disclosures and modifies
other required disclosures. The new disclosure requirements, along with modifications made to
disclosures as a result of the change in requirements for narrative descriptions of measurement
uncertainty, must be applied on a prospective basis. The effects of all other amendments included in the
guidance must be applied retrospectively for all periods presented. The adoption of this guidance
impacted disclosures only and did not have an impact on the Company's financial position or results of
operations.

In August 2018, the FASB issued new guidance that amends disclosures related to Defined Benefit Plans.
The guidance removes disclosures that no longer are considered cost-beneficial, clarifies the specific

71

requirements of certain disclosures, and adds disclosure requirements identified as relevant. The
guidance must be applied on a retrospective basis. Adoption of this guidance impacted disclosures only
and did not have an impact on the Company's financial position or results of operations.

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 adoption of this standard did not have an impact on
the Company's financial position or results of operations.

In June 2016, the FASB issued new guidance on the impairment of financial instruments. The new
guidance adds an allowance for credit losses ("CECL") impairment model that is based on expected
losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its
estimate of lifetime expected credit losses, which the FASB believes will result in more timely recognition
of such losses. The new standard is also intended to reduce the complexity of U.S. GAAP by decreasing
the number of credit impairment models that entities use to account for debt instruments. Further, the new
standard makes targeted changes to the impairment model for available-for-sale debt securities. The
adoption of this standard did not have a material impact on the Company's financial position or results of
operations.

New Accounting Pronouncements Effective January 1, 2019:

The following new accounting standard was adopted using a modified retrospective approach
through a cumulative-effect adjustment to retained earnings as of January 1, 2019:

Leases

Effective January 1, 2019, the Company adopted new guidance intended to improve financial reporting for
leases. Under the new guidance, a lessee is required to recognize assets and liabilities for leases.
Consistent with legacy GAAP, the recognition, measurement and presentation of expenses and cash
flows arising from a lease by a lessee will depend on the classification of the lease as financing or
operating. However, unlike legacy GAAP, which requires that only capital leases are recognized on the
balance sheet, the new guidance requires that both operating and financing leases be recognized on the
balance sheet. The Company adopted this new standard using a modified retrospective method, applying
the new guidance as of the beginning of the year of adoption, with a cumulative effect of initially applying
the guidance recognized as an adjustment to retained earnings at January 1, 2019. Therefore, prior
period information has not been restated. The Company has elected the package of practical expedients,
which among other things, allows historical lease classifications to be carried forward. The Company did
not elect the hindsight practical expedient in determining lease term and impairment of an entity's Right of
Use Assets ("ROU assets"). On January 1, 2019, the Company recognized a lease liability of $1.9 billion
and ROU asset of $1.7 billion, related to real estate operating leases. The ROU asset also reflected
reclassification adjustments primarily from other liabilities related to existing deferred rent, unamortized
lease incentives and restructuring liabilities of approximately $200 million upon adoption. There was no
cumulative-effect adjustment required to be booked to retained earnings upon transition. The adoption of
this standard did not have a material impact on our income statement as compared to prior periods.

The following new accounting standards were adopted prospectively as of January 1, 2019:

Derivatives and Hedging

Effective January 1, 2019, the Company adopted new guidance intended to refine and expand hedge
accounting for both financial and commodity risks. The guidance creates more transparency around how
economic results are presented in both the financial statements and the footnotes, as well as making
targeted improvements to simplify the application of hedge accounting guidance. The adoption of this
standard did not have an impact on the Company's financial position or results of operations.

72

Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income

Effective January 1, 2019, the Company adopted new guidance that allowed an entity to reclassify the
stranded tax effects resulting from the Tax Cuts and Job Act (the "TCJA") from accumulated other
comprehensive income ("AOCI") to retained earnings. The guidance is effective for the period beginning
January 1, 2019. The Company elected not to reclassify the stranded income tax effects of the TCJA from
AOCI to retained earnings. The adoption of this standard had no impact on the Company's financial
position or results of operations. The Company’s accounting policy related to releasing income tax effects
from AOCI follows the portfolio approach.

2. Revenue

The core principle of the revenue recognition 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. To
achieve that principle, the entity applies the following steps: identify the contract(s) with the customer,
identify the performance obligations in the contract(s), determine the transaction price, allocate the
transaction price to the performance obligations in the contract and recognize revenue when (or as) the
entity satisfies a performance obligation. In accordance with the accounting guidance, a performance
obligation is satisfied either at a “point in time” or “over time” depending on the nature of the product or
service provided, and the specific terms of the contract with customers.

Other revenue included in the consolidated statements of income that is not from contracts with
customers is less than 1% of total revenue, and therefore is not presented as a separate line item.

Risk and Insurance Services

Risk and Insurance Services revenue reflects compensation for brokerage and consulting services
through commissions and fees. Commission rates and fees vary in amount and can depend upon 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. For the
majority of the insurance and reinsurance brokerage arrangements, advice and services provided which
culminate in the placement of an effective policy are considered a single performance obligation.
Arrangements with clients may include the placement of a single policy, multiple policies or a combination
of policy placements and other services. Consideration related to such "bundled arrangements" is
allocated to the individual performance obligations based on their relative fair value. Revenue for policy
placement is generally recognized on the policy effective date, at which point control over the services
provided by the Company has transferred to the client and the client has accepted the services. 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. For such arrangements, revenue is recognized using output measures, which
correspond to the progress toward completing the performance obligation. Fees for non-risk transfer
services provided to clients are recognized over time in the period the services are provided, using a
proportional performance model, primarily based on input measures. These measures of progress
provide a faithful depiction of the progress towards completion of the performance obligation.

Revenue related to reinsurance brokerage for excess of loss ("XOL") treaties is estimated based on
contractually specified minimum or deposit premiums, and adjusted as additional evidence of the ultimate
amount of brokerage is received. Revenue for quota share treaties is estimated based on indications of
estimated premium income provided by the ceding insurer. The estimated brokerage revenue recognized
for quota share treaties is constrained to an amount that is probable to not have a significant negative
adjustment. The estimated revenue and the constraint are evaluated as additional evidence of the
ultimate amount of underlying risks to be covered is received over the 12 to 18 months following the
effective date of the placement.

73

In addition to commissions and fees from its clients, the Company also receives other compensation from
insurance companies. This other insurer 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). The Company is also eligible for certain
contingent commissions from insurers based on the attainment of specified metrics (i.e., volume and loss
ratio measures) relating to Marsh's placements, particularly in Marsh & McLennan Agency ("MMA") and in
parts of Marsh's international operations. Revenue for contingent commissions from insurers is estimated
based on historical evidence of the achievement of the respective contingent metrics and recorded as the
underlying policies that contribute to the achievement of the metric are placed. Due to the uncertainty of
the amount of contingent consideration that will be received, the estimated revenue is constrained to an
amount that is probable to not have a significant negative adjustment. Contingent consideration is
generally received in the first quarter of the subsequent year.

A significant majority of the Company's Risk and Insurance Services revenue is for performance
obligations recognized at a point in time. Marsh and Guy Carpenter also receive interest income on
certain funds (such as premiums and claims proceeds) held in a fiduciary capacity for others.

Insurance brokerage commissions are generally invoiced on the policy effective date. Fee based
arrangements generally include a percentage of the total fee due upon signing the arrangement, with
additional fixed installments payable over the remainder of the year. Payment terms range from receipt of
invoice up to 30 days from invoice date.

Reinsurance brokerage revenue is recognized on the effective date of the treaty. Payment terms depend
on the type of reinsurance. For XOL treaties, brokerage revenue is typically collected in four installments
during an annual treaty period based on a contractually specified minimum or deposit premium. For
proportional or quota share treaties, brokerage is billed as underlying insured risks attach to the
reinsurance treaty, generally over 12 to 18 months.

Consulting

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 receives revenue in the form of
commissions received from insurance companies for the placement of group (and occasionally individual)
insurance contracts, primarily health, life and accident coverages. Revenue for Mercer’s investment
management business and certain of Mercer’s defined benefit administration services consists principally
of fees based on assets under delegated management or administration.

Consulting projects in Mercer’s wealth and career businesses, as well as consulting projects in Oliver
Wyman Group, typically consist of a single performance obligation, which is recognized over time as
control is transferred continuously to customers. Typically, revenue is recognized over time using an input
measure of time expended to date relative to total estimated time to be incurred at project completion.
Incurred hours represent services rendered and thereby faithfully depicts the transfer of control to the
customer.

On a limited number of engagements, performance fees may also be earned for achieving certain
prescribed performance criteria. Revenue for achievement is estimated and constrained to an amount
that is probable to not have a significant negative adjustment.

A significant majority of fee revenues in the Consulting segment is recognized over time.

For consulting projects, Mercer generally invoices monthly in arrears with payment due within 30 days of
the invoice date. Fees for delegated management services are either deducted from the net asset value
of the fund or invoiced to the client on a monthly or quarterly basis in arrears. Oliver Wyman Group
typically bills its clients 30-60 days in arrears with payment due upon receipt of the invoice.

Health brokerage and consulting services are components of both Marsh, which includes MMA, and
Mercer, with approximately 60% of such revenues reported in Mercer. Health contracts typically involve a
series of distinct services that are treated as a single performance obligation. Revenue for these services
is recognized over time based on the amount of remuneration the Company expects to be entitled in
exchange for these services. Payments for health brokerage and consulting services are typically paid
monthly in arrears from carriers based on insured lives under the contract.

The Company records accounts receivable when the right to consideration is unconditional, subject only
to the passage of time. Contract assets primarily relate to quota share reinsurance brokerage and
contingent insurer revenue. The Company does not have the right to bill and collect revenue for quota
share brokerage until the underlying policies written by the ceding insurer attach to the treaty. Estimated
revenue related to achievement of volume or loss ratio metrics cannot be billed or collected until all
related policy placements are completed and the contingency is resolved. The change in contract assets
from January 1, 2020 to December 31, 2020 is primarily due to $311 million of additions during the period,
partly offset by $284 million transferred to accounts receivables, as the rights to bill and collect became
unconditional. The change in contract assets from January 1, 2019 to December 31, 2019 is primarily due
to $437 million of additions during the period offset by $342 million transferred to accounts receivables.
Contract assets are included in other current assets in the Company's consolidated balance sheets.
Contract liabilities primarily relate to the advance consideration received from customers. Contract
liabilities are included in current liabilities in the Company's consolidated balance sheets. The change in
contract liabilities from January 1, 2020 to December 31, 2020 includes cash received for performance
obligations not yet fulfilled of $615 million offset by revenue recognized in 2020 of $527 million that was
included in the contract liability balance at the beginning of the year. The Company recognized revenue of
$531 million in 2019 that was included in the contract liability balance at January 1, 2019.

75

The Company recognizes commission revenue from arrangements for a significant portion of its
brokerage arrangements at a point in time at effective date of the underlying policy. Commission revenue
is estimated using historical information about the risks to be covered over the policy period, some of
which are dependent on variable factors such as number of employees covered, covered payroll, airline
passenger miles flown, shipped tonnage of marine cargo and others. For the year ended December 31,
2020, the Company recorded a revenue reduction of $42 million for estimated commission revenue
accounted for on a point in time basis. The reduction primarily relates to policy inception periods from the
third quarter of 2019 through the second quarter of 2020.

The amount of revenue recognized in 2020 and 2019 from performance obligations satisfied in previous
periods, mainly due to variable consideration from contracts with insurers, quota share business and
consulting contracts previously considered constrained was $97 million and $79 million, respectively.

The Company applies the practical expedient and therefore does not disclose the value of unsatisfied
performance obligations for (1) contracts with original contract terms of one year or less and (2) contracts
where the Company has the right to invoice for services performed. The revenue expected to be
recognized in future periods during the non-cancellable term of existing contracts greater than one year
that is related to performance obligations that are unsatisfied or partially satisfied at the end of the
reporting period is approximately $38 million for Marsh, $184 million for Mercer and $6 million for Oliver
Wyman Group. The Company expects revenue in 2021, 2022, 2023, 2024 and 2025 and beyond of $135
million, $64 million, $22 million, $6 million and $1 million, respectively, related to these performance
obligations.

Costs to Obtain and Fulfill a Contract

The Company capitalizes the incremental costs to obtain contracts primarily related to commissions or
sales bonus payments in both segments. These deferred costs are amortized over the expected life of the
underlying customer relationships.

In Risk and Insurance Services, the Company capitalizes certain pre-placement costs that are considered
fulfillment costs that meet the following criteria: these costs (1) relate directly to a contract, (2) enhance
resources used to satisfy the Company’s performance obligation and (3) are expected to be recovered
through revenue generated by the contract. These costs are amortized at a point in time when the
associated revenue is recognized.

In Consulting, the Company incurs implementation costs necessary to facilitate the delivery of the
contracted services. These costs are capitalized and amortized over the initial contract term plus
expected renewal periods.

At December 31, 2020, the Company’s capitalized assets related to deferred implementation costs, costs
to obtain and costs to fulfill were $29 million, $253 million and $296 million, respectively. At December 31,
2019, the Company's capitalized assets related to deferred implementation costs, costs to obtain and
costs to fulfill were $30 million, $222 million, and $262 million, respectively. Costs to obtain and deferred
implementation costs are primarily included in other assets and costs to fulfill are primarily included in
other current assets in the Company's consolidated balance sheets. The Company recorded amortization
of compensation and benefits expense of $1.3 billion and $1.2 billion for the years ended December 31,
2020 and 2019, respectively, related to these capitalized costs.

A significant portion of deferred costs to fulfill in Risk and Insurance Services is amortized within three to
six months. Therefore, the deferral of the cost and its amortization often occur in the same annual period.

The Company has elected to use the practical expedient and recognizes the incremental costs of
obtaining contracts as an expense when incurred if the amortization period of the assets is one year or
less.

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).

The following amounts are included in the consolidated statements of cash flows as a financing activity.
The Company paid deferred and contingent consideration of $122 million in the year ended December 31,
2020, consisting of deferred purchase consideration of $68 million and contingent purchase consideration
of $54 million. In the year ended December 31, 2019, the Company paid deferred and contingent
consideration of $65 million, consisting of deferred purchase consideration of $43 million and contingent
consideration of $22 million, and in the year ended December 31, 2018 the Company paid deferred and
contingent consideration of $117 million, consisting of deferred purchase consideration of $62 million and
contingent consideration of $55 million.

The following amounts are included in the operating section of the consolidated statements of cash flows.
For the year ended December 31, 2020, the Company recorded a net charge for adjustments to
acquisition related accounts of $26 million and contingent consideration payments of $48 million. For the
year ended December 31, 2019, the Company recorded a net charge for adjustments to acquisition
related accounts of $68 million and contingent consideration payments of $41 million, and for the year
ended December 31, 2018 the Company recorded a net charge for adjustments to acquisition related
accounts of $32 million and contingent consideration payments of $36 million.

The Company had non-cash issuances of common stock under its share-based payment plan of $219
million, $165 million and $130 million for the years ended December 31, 2020, 2019 and 2018,
respectively. The Company recorded share-based compensation expense related to restricted stock units,
performance stock units and stock options of $290 million, $252 million and $193 million for the years
ended December 31, 2020, 2019 and 2018, respectively.

On January 1, 2019, the Company adopted the new accounting guidance related to leases, which
requires a lessee to recognize assets and liabilities for its leases. Upon adoption of this accounting
standard, the Company recorded a non-cash ROU asset of $1.7 billion and lease liability of $1.9 billion in
the first quarter of 2019.

Allowance for Credit Losses on Accounts Receivable

On January 1, 2020, the Company adopted the new guidance on the impairment of financial instruments.
The Company’s policy for providing an allowance for credit losses on its accounts receivable is a
combination of factors, including historical write-offs, aging of balances, and other qualitative and
quantitative analyses.

77

An analysis of the allowance for credit losses for the year ended December 31, 2020 is provided below.

5. Acquisitions and 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
values of the net tangible assets and the identifiable intangible assets purchased, which typically consist
of customer relationships, developed technology, trademarks and non-compete agreements. The
valuation of purchased intangible assets involves significant estimates and assumptions. The Company
estimates the fair value of purchased intangible assets, primarily using the income approach, by
determining the present value of future cash flows over the remaining economic life of the respective
assets. The significant estimates and assumptions used in this approach include the determination of the
discount rate, economic life, future revenue growth rates, expected account attrition rates and earnings
margins. Refinement and completion of final valuation of net assets acquired could affect the carrying
value of tangible assets, goodwill and identifiable intangible assets.

The Risk and Insurance Services segment completed seven acquisitions during 2020.

•

•

•

•

January – Marsh & McLennan Agency ("MMA") acquired Momentous Insurance Brokerage Inc., a
California-based full-service risk management and employee benefits firm specializing in high net
worth private client services and insurance solutions for the entertainment industry, and Ironwood
Insurance Services, LLC, an Atlanta-based broker that provides commercial property/casualty
insurance, employee benefits, and private client solutions to mid-size businesses and individuals
across the U.S.

April – MMA acquired Assurance Holdings, Inc., an Illinois-based full service brokerage providing
business insurance, employee benefits, private client insurance, and retirement services to
businesses and individuals across the U.S.

June – MMA acquired Nico Insurance Services, Inc., a California-based agency providing
employee benefits solutions to groups and individuals.

December – MMA acquired Heritage Insurance Services, Inc., a Kentucky-based full service
broker that provides commercial property and casualty and personal lines primarily in the trucking
and transportation industry, Inspro Insurance, Inc., a Nebraska-based full service broker that
provides commercial property and casualty insurance, personal lines and employee benefits
services, and Compass Financial Partners, LLC, a North Carolina-based retirement consulting
and investment advisory firm.

Total purchase consideration for acquisitions made during 2020 was approximately $877 million, which
consisted of cash paid of $694 million and deferred purchase and estimated contingent consideration of
$183 million. Contingent consideration arrangements are based primarily on earnings before interest, tax,
depreciation and amortization ("EBITDA") or revenue targets over a period of two to four years. During
2020, the Company also paid $68 million of deferred purchase consideration and $102 million of
contingent consideration related to acquisitions made in prior years. Estimated fair values of assets
acquired and liabilities assumed are subject to adjustment when purchase accounting is finalized.

The following table presents the preliminary allocation of purchase consideration to the assets acquired
and liabilities assumed during 2020 based on the estimated fair values for the acquisitions as of their
respective acquisition dates:

The purchase price allocation above is based on estimates that are preliminary in nature and subject to
adjustments, which could be material. Any necessary adjustments must be finalized during the
measurement period, which for a particular asset, liability, or non-controlling instrument ends once the
acquirer determines that either (1) the necessary information has been obtained or (2) the information is
not available. However, the measurement period for all items is limited to one year from the acquisition
date.

Items subject to change include:

•

•

•

•

Amounts of intangible assets, fixed assets, capitalized software assets and right-of-use assets,
subject to finalization of valuation efforts;

Amounts for contingencies, pending the finalization of the Company’s assessment of the portfolio
of contingencies;

Amounts for deferred tax assets and liabilities pending the finalization of valuations of the assets
acquired, liabilities assumed and associated goodwill discussed below; and

Amounts for income tax assets, receivables and liabilities, pending the filing of the acquired
companies' pre-acquisition income tax returns and receipt of information from taxing authorities
which may change certain estimates and assumptions used.

The estimation of fair value requires numerous judgments, assumptions and estimates about future
events and uncertainties, which could materially impact these values, and the related amortization, where
applicable, in the Company’s results of operations.

The consolidated statement of income for 2020 includes approximately $169 million of revenue and
operating income of $11 million related to acquisitions made during 2020. The consolidated statement of
income for 2019 includes approximately $1.2 billion of revenue and $40 million of operating loss related to
acquisitions made during 2019, and the consolidated statement of income for 2018 includes
approximately $120 million of revenue and $2 million of operating income related to acquisitions made
during 2018.

In 2020, the Company incurred acquisition-related costs of $3 million, primarily related to legal fees. In
2019, the Company incurred acquisition-related costs, primarily related to legal, investment banking and
U.K. stamp duty tax of $125 million, primarily related to the acquisition of JLT. Acquisition-related costs
incurred in 2018 were $7 million. These costs are included in other operating expenses in the Company's
consolidated statement of income.

Dispositions

During 2020, the Company sold certain businesses primarily in the U.S., U.K. and Canada for cash
proceeds of approximately $98 million.

At December 31, 2019, the Company owned approximately 443 million shares of the common stock of
Alexander Forbes ("AF"), a South African company listed on the Johannesburg Stock Exchange, which
was accounted for under the equity method of accounting. In February 2020, the Company sold
approximately 49 million shares of the common stock of AF, and in May 2020, sold an additional 193
million shares to third parties, leaving the Company with an investment of approximately 201 million
shares of the common stock of AF at December 31, 2020. Upon completion of the May transaction, the
investment in AF is accounted at fair value, with unrealized gains and losses recorded as investment
(loss) income in the consolidated statement of income.

Prior year acquisitions

On April 1, 2019, the Company completed the JLT Transaction and purchased all of the outstanding
shares of JLT. Under the terms of the Transaction, JLT shareholders received £19.15 in cash for each JLT
share, which valued JLT’s existing issued and to be issued share capital at approximately £4.3 billion (or
approximately $5.6 billion based on an exchange rate of U.S. $1.31:£1). The Company also assumed
existing JLT long-term indebtedness of approximately $1 billion. The Company implemented the
Transaction by way of a scheme of arrangement under Part 26 of the United Kingdom Companies Act
2006, as amended.

The Transaction strengthened MMC’s leadership position in insurance and reinsurance broking and
health and retirement. The addition of over 10,000 colleagues provided deeper industry expertise in
almost every part of the Company. The Transaction also builds on MMC’s efforts to expand in faster-
growing geographies and market segments, and facilitates investment in data and analytics.

During 2019, the Risk and Insurance Services segment completed five other acquisitions.

•

•

February – MMA acquired Bouchard Insurance, Inc., a Florida-based full service agency and
Employee Benefits Group, Inc., a Maryland-based independent insurance agency.

April – MMA acquired Lovitt & Touche, Inc., an Arizona-based insurance agency and The
Centurion Group, LLC, a Pennsylvania-based retirement consulting, asset management and
benefit plan advisory firm.

• October – MMA acquired Benefits Reports Insurance Services, Inc., a Massachusetts-based

independent insurance agency.

Total purchase consideration for acquisitions made during 2019 was approximately $5,927 million, which
consisted of cash paid of $5,861 million and deferred purchase and estimated contingent consideration of
$66 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 2019, the
Company also paid $43 million of deferred purchase consideration and $63 million of contingent
consideration related to acquisitions made in prior years.

83

Subsequent to the JLT acquisition, the Company purchased the outstanding non-controlling interests of
several JLT subsidiaries for cash payments of approximately $79 million.

In January 2019, Marsh increased its equity ownership in Marsh India from 26% to 49%. Marsh India is
accounted for under the equity method.

Prior year dispositions

During the third quarter of 2019, the Company completed the sale of a U.S. Specialty business at Marsh
and a U.S. large market health and defined benefit business at Mercer for cash proceeds of
approximately $60 million. Also, on June 1, 2019, the Company completed its disposition of JLT’s global
aerospace business for cash proceeds of $165 million and contingent consideration receivable of
approximately $65 million, based on the aerospace business achieving certain revenue milestones in
2020. The aerospace business was divested as part of the European Commission's approval of the JLT
Transaction.

6. 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, a company can assess qualitative factors to
determine whether it is necessary to perform a quantitative goodwill impairment test. Alternatively, the
Company may elect to proceed directly to the quantitative goodwill impairment test. In 2020, the
Company elected to perform a qualitative impairment assessment. As part of its assessment, the
Company considered numerous factors, including:

•

•

that the fair value of each reporting unit exceeds its carrying value by a substantial margin based
on its most recent quantitative assessment in 2019;

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;

84

•

•

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 2020 and concluded that
goodwill was not impaired.

Other intangible assets that are not deemed to have an indefinite life are amortized over their estimated
lives and assessed for impairment upon the occurrence of certain triggering events in accordance with
applicable accounting literature. Based on its assessment, the Company concluded that other intangible
assets were not impaired. The Company does not have any indefinite lived intangible assets.

respectively, which is deductible for tax purposes, primarily related to the Risk and Insurance Services
segment.

Goodwill allocable to the Company’s reportable segments is as follows: Risk and Insurance Services,
$11.7 billion and Consulting, $3.8 billion.

The amount of cumulative undistributed earnings that are indefinitely reinvested in non-U.S. subsidiaries
is approximately $700 million as of December 31, 2020. While no additional U.S. federal income tax
would be required if such earnings were repatriated, additional state and withholding taxes would apply.
The amount of these additional taxes is estimated to be approximately $60 million.

Future U.S. federal tax costs related to basis differences in Non-U.S. subsidiaries would primarily be
realized through the U.S. GILTI tax regime. The Company elected to recognize GILTI tax costs as a
period cost and therefore, has not provided deferred tax liabilities on these basis differences.

A reconciliation from the U.S. Federal statutory income tax rate to the Company’s effective income tax
rate is shown below:

The Company’s consolidated effective tax rate was 26.7%, 27.3% and 25.6% in 2020, 2019 and 2018,
respectively. The rates in all periods reflect the effects of tax planning and the ongoing impact of the Tax
Cuts and Jobs Act ("TCJA"), including regulatory and other guidance as it became available. The tax rate
in 2020 includes a valuation allowance for certain tax credits, the impact of uncertain tax positions, and
certain tax planning benefits. The 2019 rate includes certain tax costs related to JLT integration and
restructuring activity. The 2018 rate includes the effect of a charge related to the Company’s investment in
Alexander Forbes.

A valuation allowance was recorded to adjust deferred tax assets to the amount that the Company
believes is more likely than not to be realized. Valuation allowances had net increases of $72 million, $60
million and $36 million in 2020, 2019 and 2018, respectively. Adjustments of the beginning of the year
balances of valuation allowances decreased income tax expense by $14 million during 2020. There was
no change to income tax expense as a result of adjustments of the beginning of the year valuation
allowances in 2019, while in 2018 changes to the beginning of year valuation allowance increased income
tax expense by $1 million. Approximately 58% of the Company’s net operating loss carryforwards expire
from 2021 through 2037, and others are unlimited. The potential tax benefit from net operating loss
carryforwards at the end of 2020 comprised federal, state and local, and non-U.S. tax benefits of $24
million, $25 million, and $94 million, respectively, before reduction for valuation allowances.

Of the total unrecognized tax benefits at December 31, 2020, 2019 and 2018, $90 million, $75 million and
$64 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,
2020, 2019 and 2018, before any applicable federal benefit, was $40 million, $31 million and $15 million,
respectively.

The Company is routinely examined by the jurisdictions in which it has significant operations. In the U.S.
federal jurisdiction, the Company participates in the Internal Revenue Service’s (IRS) Compliance
Assurance Process (CAP), which is structured to be, in effect, a real-time audit. The IRS is currently
examining the Company’s 2017, 2018 and 2019 tax returns. The Company was accepted into the
Bridge phase of the CAP process for tax year 2020.

New York is a significant tax jurisdiction for the Company. During 2019, New York State initiated an audit
for the 2015 tax year; and during 2020 included the 2016 tax year. During 2020, New York City initiated an
audit for tax years 2016 through 2018. During 2018, New York State and New York City closed the
examination of tax years 2007 through 2009. In addition, New York State and New York City have
continuing examinations underway for various entities covering the years 2010 through 2014.

The Company has established liabilities for uncertain tax positions in relation to potential assessments in
the jurisdictions in which it operates. 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 $33 million within the next twelve months due to settlement of
audits and expiration of statutes of limitation.

8. 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

*Rate of compensation increase assumptions 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 and earned benefits are not subject to final salary level adjustments.

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 2020, the actual allocation for the U.S. plans was 64% equities and equity
alternatives and 36% fixed income. The target asset allocation for the U.K. plans, which comprise
approximately 81% of non-U.S. plan assets, is 32% equities and equity alternatives and 68% fixed
income. At the end of 2020, the actual allocation for the U.K. plans was 33% equities and equity
alternatives and 67% 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 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.

89

Changes to Pension Plans

As part of the JLT Transaction, the Company assumed responsibility for a number of pension plans
throughout the world, the most significant of which is the JLT U.K. plan. The JLT U.K. plan has a defined
benefit section which was frozen to future accrual in 2006 and a defined contribution section. The assets
of the scheme are held in a trustee administered fund separate from the Company.

Defined Benefit Pension Plans in the U.K. and certain other countries 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, 2018, the lump sum payments exceeded the settlement thresholds in
two of the U.K. plans. The Company recorded non-cash settlement charges of $42 million in the
consolidated statements of income for the year ended December 31, 2018, primarily related to these
plans. The Company recorded $3 million and $7 million of non-cash settlement charges for the years
ended December 31, 2020 and 2019, respectively, related to other non-U.S. plans.

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.

90

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 29-35% for equities and equity
alternatives, and 65-71% 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 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. The vast majority of unrecognized losses relate to inactive
plans and are amortized over the remaining life expectancy of the participants.

The 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 $6.9 billion and $5.1 billion, respectively, as
of December 31, 2020 and $6.3 billion and $4.7 billion, respectively, as of December 31, 2019.

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 $6.9 billion and $5.1 billion, respectively, as of December 31,
2020 and $6.3 billion and $4.7 billion, respectively, as of December 31, 2019. The increase in the benefit
obligation in 2020 compared to 2019 reflects the decrease in discount rates used to measure plan
liabilities.

As of December 31, 2020, the U.S. qualified plan holds 2 million shares of the Company’s common stock
which were contributed to the qualified plan by the Company in 2005. This represented approximately
4.6% of that plan's assets as of December 31, 2020.

The assumed health care cost trend rate for Medicare eligibles and non-Medicare eligibles is
approximately 5.8% in 2020, 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%.

Estimated Future Contributions

The Company expects to contribute approximately $37 million to its U.S. plans in 2021. 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 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 $3.1 billion and $2.5 billion, respectively,
as of December 31, 2020 and $2.7 billion and $2.2 billion, respectively, as of December 31, 2019.

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 $3.3 billion and $2.6 billion, respectively, as of
December 31, 2020 and $3.0 billion and $2.3 billion, respectively, as of December 31, 2019.

The increase in the benefit obligation in 2020 compared to 2019 reflects an actuarial loss primarily due to
the decrease in discount rates used to measure plan liabilities.

The assumed health care cost trend rate was approximately 4.93% in 2020, gradually declining to 4.22%
in 2040. Assumed health care cost trend rates can have a significant effect on the amounts reported for
the non-U.S. health care plans.

Estimated Future Contributions

The Company expects to contribute approximately $87 million to its non-U.S. pension plans in 2021.
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. For the

97

MMC UK Pension Fund, in November 2016, the Company and the trustee agreed to a funding deficit
recovery plan for the U.K. defined benefit pension plans. A new agreement was reached with the trustee
in fourth quarter of 2019 based on the surplus funding position at December 31, 2018. Under the
agreement no deficit funding is required until 2023. The funding level will be re-assessed during 2022 to
determine if contributions are required in 2023. As part of a long-term strategy, which depends on having
greater influence over asset allocation and overall investment decisions, in November 2019 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 addition, in the U.K., the Company assumed responsibility for JLT's Pension Scheme (JLT U.K. plan).
We currently expect to pay $29 million of deficit funding in 2021, although we will also reach a new
funding agreement with the trustee during 2021.

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. See Note
10 for further description of fair value hierarchy leveling.

The following table sets forth, by level within the fair value hierarchy, a summary of the U.S. and non-U.S.
plans' investments measured at fair value on a recurring basis at December 31, 2020 and 2019:

(a) Transfers in during 2019 are primarily related to the inclusion of JLT plan assets.

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.

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.

100

Net derivative liabilities: Includes interest rate swaps, inflation swaps, total return swaps, repurchase
agreements and equity based derivatives, primarily related to the U.K. plans. These derivatives are
structured to hedge interest rate, inflation and equity exposure in the U.K. plans. Fair values for interest
rate, inflation and equity based derivatives are calculated 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.

In the prior year, the invested assets and hedging derivatives in the U.K. plans were structured as a
pooled fund and disclosed in the leveling chart in the common/collective trust category and measured at
fair value based on NAV. In the fourth quarter of 2020, the Company restructured the U.K. plans'
investment portfolio to segregate its asset and hedging instruments by specific investment categories.

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 ("MMC 401(k) Plan") and the Marsh &
McLennan Agency Savings and Investment Plan (collectively, the "401(k) Plans"), that are qualified under
U.S. tax laws. For the 401(k) Plans, eligible employees may contribute a percentage of their base salary,
subject to certain limitations, and the Company matches a fixed portion of the employees’ contributions. In
addition, the Company also amended the MMC 401(k) Plan 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) Plans contain an Employee Stock Ownership Plan feature under U.S. tax law. Approximately $537
million of the 401(k) Plans' assets at December 31, 2020 and $556 million at December 31, 2019 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 $145 million in 2020, $139 million in 2019 and $133 million in 2018. In addition, the Company has
significant defined contribution plans 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. In addition, the Company has assumed responsibility for the defined contribution section
of the JLT U.K. plan. The cost of the U.K. defined contribution plan was $121 million, $100 million and $80
million in 2020, 2019 and 2018, respectively.

9. Stock Benefit Plans

The Company maintains multiple stock-based payment arrangements under which employees may be
awarded restricted stock units, stock options and other forms of stock-based benefits.

Marsh & McLennan Companies, Inc. Incentive and Stock Award Plans

On May 21, 2020, the Marsh & McLennan Companies, Inc. 2020 Incentive and Stock Award Plan (the
"2020 Plan") was approved by the Company's stockholders. The 2020 Plan replaced the Company's
previous equity incentive plan (2011 Incentive and Stock Award Plan).

The types of awards permitted under the 2020 Plan include stock options, restricted stock units payable in
Company common stock or cash, and other stock-based awards. Performance-based restricted stock
units are referred to as performance stock units. The 2020 Plan contains a provision which, in the event of
a change in control of the Company, may accelerate the vesting of awards. This provision requires both a
change in control of the Company and a subsequent specified termination of employment for vesting to
be accelerated. There are 20 million shares available for issuance under the 2020 plan. The total number
of shares issued in connection with full-value awards may not exceed 12.5 million shares. Full-value
awards include awards such as restricted stock units and performance stock units but exclude stock
options.

The Company's current practice is to grant non-qualified stock options, restricted stock units ("RSUs")
and/or performance stock units ("PSUs") on an annual basis to senior executives and a limited number of

101

other employees as part of their total compensation. RSU awards are also granted to new hires or as
retention awards for certain employees.

Stock Options: The Company currently grants non-qualified stock options under the 2020 Plan. The
Compensation Committee determines when the options vest and may be exercised and under what terms
the options are forfeited. 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 year 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 expected dividend yield is
based on expected dividends for the expected life of the stock options.

The assumptions used in the Black-Scholes option pricing valuation model for options granted by the
Company in 2020, 2019 and 2018 are as follows:

Risk-free interest rate
Expected life (in years)
Expected volatility
Expected dividend yield

20.33 %
1.53 %

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, 2020, 2019 and
2018 was $21.09, $17.87 and $18.29, respectively. The total intrinsic value of options exercised during
the same periods was $159.3 million, $136.7 million and $72.9 million, respectively.

As of December 31, 2020, there was $17.5 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 1.23 years. Cash received from the exercise of stock options for the years
ended December 31, 2020, 2019 and 2018 was $72.0 million, $106.5 million and $46.7 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: The Company currently grants RSU and PSU
awards under the 2020 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.
Dividend equivalents are not paid out unless and until such time that the award vests and shares are

102

distributed. For PSU's granted prior to 2020, payout is based on the achievement of the Company's
performance measures, based on adjusted EPS growth as modified for executive compensation purposes
and measured on a three-year annualized growth basis, and paid out generally over the 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.

The payout for PSU awards granted in 2020 is based on the achievement of the Company's adjusted
EPS growth as well as a relative total stockholder return ("TSR") modifier versus the S&P 500 companies.
The TSR modifier is a market condition with the grant-date fair value determined using a Monte Carlo
simulation model. The Monte Carlo model takes into account several factors and assumptions including
the risk-free interest rate, historical volatility of and correlations between the stock prices of the Company
and the S&P 500 companies, and the Company’s relative TSR versus S&P 500 companies for the brief
portion of the three-year performance period prior to the grant date. The number of shares actually
earned at the end of the three-year period will vary, based on actual Company financial performance, and
for 2020 PSU awards, relative TSR, from 0% to 200%% of the number of performance share units
granted.

The assumptions used in the Monte Carlo simulation model for PSU's granted with the TSR modifier by
the Company in 2020 include:

Risk-Free Interest Rate

Volatility

1.39 %

date fair value of the Company's PSU awards granted during the years ended December 31, 2019 and
2018 was $91.17 and $83.05, respectively. The total fair value of the shares distributed during the years
ended December 31, 2020, 2019 and 2018 in connection with the Company's non-option equity awards
was $290.0 million, $211.9 million and $170.3 million, respectively.

The payout of shares in 2020 with respect to the PSU awards granted in 2017 was 168% of target based
on performance for the three-year performance period. In aggregate, 354,452 shares became
distributable in respect to PSUs vested in 2020.

103

As of December 31, 2020, there was $347.7 million of unrecognized compensation cost related to the
Company's RSU and PSU awards. The weighted-average period over which that cost is expected to be
recognized is approximately 1 year.

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 and the addition of 4,750,000 shares due to a shareholder action in May 2018, no more than
40,350,000 shares of the Company's common stock may be sold. Employees purchased 394,419 shares
during the year ended December 31, 2020 and at December 31, 2020, 4,878,288 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, the addition of 4,000,000 shares
due to a shareholder action in May 2007 and reducing the shares available by 1,000,000 consistent with
the Company's Board of Directors' action in March 2018, no more than 11,000,000 shares of the
Company's common stock may be sold. Employees purchased 115,199 shares during the year ended
December 31, 2020 and there were 1,156,014 shares available for issuance at December 31, 2020 under
the International Plan. The plans are considered non-compensatory.

10. 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).

Assets and liabilities using Level 2 inputs are related to an equity security.

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

104

measurement. These inputs reflect management’s own assumptions about the
assumptions a market participant would use in pricing the asset or liability.

Assets and liabilities measured using Level 3 inputs relate to assets and liabilities for contingent purchase
consideration.

Valuation Techniques

Equity Securities, Money Market Mutual 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 mutual funds are
valued using a valuation technique that results in price per share at $1.00.

Contingent Purchase Consideration Assets and Liability - Level 3

Purchase consideration for some acquisitions and dispositions made by the Company include contingent
consideration arrangements. Contingent consideration arrangements are based primarily on EBITDA or
revenue targets over a period of two to four years. The fair value of contingent purchase consideration
asset and liability is estimated as the present value of future cash flows to be paid, based on projections
of revenue and earnings and related targets of the acquired and disposed entities.

The following fair value hierarchy table presents information about the Company’s assets and liabilities
measured at fair value on a recurring basis as of December 31, 2020 and 2019:

The Level 3 assets in the above chart reflect contingent purchase consideration from the sale of
businesses during 2019. The change in the asset from December 31, 2019 is primarily due to the net
impact of accretion and adjustments to the fair value of the acquisition related asset of approximately
$15 million. A 5% increase or decrease in the projections used to estimate the contingent consideration
would result in a corresponding increase or decrease of the asset of approximately $7 million.

105

During the year ended December 31, 2020, 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, 2020 and December 31, 2019.

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 $11 million for the year ended December 31, 2020. A 5% increase
in the projections used to estimate the contingent consideration would increase the liability by
approximately $12 million. A 5% decrease would decrease the liability by approximately $21 million.

Long-Term Investments

The Company holds investments in certain private equity investments and private companies that are
accounted for using the equity method of accounting. The carrying value of these investments was $280
million and $434 million at December 31, 2020 and 2019, respectively.

Investments in Public and Private Companies

The Company has other investments in private insurance and consulting companies with a carrying value
of $169 million and $183 million at December 31, 2020 and December 31, 2019, respectively. The
Company’s equity investment in insurance and consulting companies are accounted for using the equity
method of accounting, the results of which are included in revenue in the consolidated statements of
income 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, some of which are on
a one quarter lag basis.

Private Equity Investments

The Company's investments in private equity funds were $111 million and $107 million at December 31,
2020 and December 31, 2019, 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 its
proportionate share of the change in fair value of the funds on the investment income (loss) line in the
consolidated statement of income. These investments are included in other assets in the consolidated
balance sheets. The Company recorded net investment income of $3 million and $13 million from these
investments for the years ended December 31, 2020 and 2019, respectively.

Other Investments

At December 31, 2020 and December 31, 2019 the Company held certain equity investments with readily
determinable market values of $72 million and $19 million, respectively. In 2020 and 2019, the Company
recorded investment losses on these investments of $27 million and gains of $10 million, respectively.
The Company also held investments without readily determinable market values of $33 million and $67
million at December 31, 2020 and 2019, respectively. The Company recorded a net gain of approximately
$2 million in 2020 and a net loss of approximately $1 million in 2019 on these investments.

At December 31, 2019, the Company owned approximately 443 million shares of the common stock of
AF, a South African company listed on the Johannesburg Stock Exchange, which was accounted for

106

under the equity method of accounting. In February 2020, the Company sold approximately 49 million
shares of the common stock of AF, and in May 2020, sold an additional 193 million shares to third parties,
leaving the Company with an investment of approximately 201 million shares of the common stock of AF
at December 31, 2020. Upon completion of the May transaction, the investment in AF was accounted at
fair value, with investment gains and losses recorded as investment income (loss) in the consolidated
statement of income. The fair value of AF at December 31, 2020 was $54 million.

In March 2019, the Company disposed of its investment in BenefitFocus for total proceeds of
approximately $132 million. The Company received $115 million in the first quarter of 2019 and $17
million in April 2019. During the second quarter of 2019, the Company disposed of its investment in
Payscale and received approximately $47 million.

11. Derivatives

Net Investment Hedge

The Company has investments in various subsidiaries with Euro functional currencies. As a result, the
Company is exposed to the risk of fluctuations between the Euro and U.S. dollar exchange rates. The
Company designated its €1.1 billion senior note debt instruments ("euro notes") as a net investment
hedge (the "hedge") of its Euro denominated subsidiaries. The hedge effectiveness is re-assessed each
quarter to confirm that the designated equity balance at the beginning of each period continues to equal
or exceed 80% of the outstanding balance of the Euro debt instrument and that all the critical terms of the
hedging instrument and the hedged net investment continue to match. If the Company concludes that the
hedge is highly effective, the change in the debt balance related to foreign exchange fluctuations is
recorded in foreign currency translation gains (losses) in the consolidated balance sheet. The Company
concluded that the hedge continues to be highly effective as of December 31, 2020. During 2020, the
U.S. dollar value of the euro notes increased $124 million through December 31, 2020 due to the impact
of foreign exchange rates, with a corresponding increase to accumulated other comprehensive loss.

JLT Acquisition Related Derivatives

On September 20, 2018, the Company entered into the FX contract to purchase £5.2 billion at a
contracted exchange rate, to hedge the risk of appreciation of the GBP-denominated purchase price of
JLT, which was settled on April 1, 2019 upon the closing of the JLT Transaction. The FX contract did not
qualify for hedge accounting treatment under applicable accounting guidance, which required the
Company to record the change in the fair value of the FX contract on each reporting date to the statement
of income. The Company recorded a gain of $31 million in the consolidated statement of income for the
year ended December 31, 2019, related to the settlement of the FX Contract. An unrealized loss of $325
million related to the change in fair value of the FX contract was recorded in the consolidated statement of
income during 2018.

In connection with the JLT Transaction, to hedge the economic risk of changes in future interest rates
prior to its issuance of fixed rate debt, in the fourth quarter of 2018, the Company entered into treasury
locks related to $2 billion of senior notes issued in January 2019. The fair value of the treasury locks at
December 31, 2018 was based on the published treasury rate plus the forward premium as of December
31, 2018 compared to the all in rate at the inception of the contract. The contracts were not designated as
an accounting hedge. The Company recorded an unrealized loss of $116 million related to the change in
the fair value of this derivative in the consolidated statement of income for the twelve months ended
December 31, 2018. In January 2019, upon issuance of the $5 billion of senior notes, the Company
settled the treasury lock derivatives and made a payment to its counter party for $122 million. A charge of
$6 million was recorded in the first quarter of 2019 related to the settlement of the treasury lock
derivatives.

In March 2019, the Company issued €1.1 billion of senior notes related to the JLT Transaction. See Note
13 for additional information related to the Euro senior note issuances. In connection with the senior note
issuances, the Company entered into a forward exchange contract to hedge the economic risk of changes
in foreign exchange rates from the issuance date to settlement date of the Euro senior notes. The
Company recorded a charge of $7.3 million in the consolidated statement of income for the year ended
December 31, 2019, related to the settlement of this contract.

107

JLT Derivatives and Hedging Activity

A significant portion of JLT's outstanding senior notes at the time of completion of the JLT Transaction
were denominated in U.S. dollars. In order to hedge its exposure against the risk of fluctuations between
the British pound and the U.S. dollar, JLT entered into foreign exchange contracts as well as interest rate
swaps to protect against the risk of changes in interest rates, which were designated as fair value hedges.
In June, 2019, the Company redeemed these U.S. dollar denominated senior notes and settled the
related derivative contracts. The offsetting changes in fair value of the debt and the change in fair value of
the derivative contracts were recorded in the consolidated statement of income for the year ended
December 31, 2019.

JLT also had a number of foreign exchange contracts to hedge the risk of foreign exchange movements
between the U.S. dollar and the British pound, related to JLT’s U.S. dollar denominated revenue in the
U.K. Prior to the acquisition, these derivative contracts were designated as cash flow hedges. Upon
completion of the JLT Transaction, these derivative contracts were not re-designated as cash flow hedges
by the Company. The contracts were settled in June 2019. The change in fair value between the
acquisition date and the settlement date resulted in a charge of $26 million for the year ended December
31, 2019. The charge is recorded as a change in fair value of acquisition related derivative contracts in
the consolidated statement of income.

12. Leases

Effective January 1, 2019 (the "implementation date"), the Company adopted new guidance intended to
improve financial reporting for leases. A lease is defined as a party obtaining the right to use an asset
legally owned by another party. The Company determines if an arrangement is a lease at inception. For
operating leases entered into prior to January 1, 2019, the Right-of-Use ("ROU") assets and operating
lease liabilities were recognized in the balance sheet on the implementation date based on the present
value of the remaining future minimum payments over the lease term from the implementation date. This
ROU asset was adjusted for unamortized lease incentives and restructuring liabilities that existed on the
implementation date. For leases entered into subsequent to January 1, 2019, the operating lease ROU
asset and operating lease liabilities are based on the present value of minimum payments over the lease
term at the commencement date of the lease.

The Company uses discount rates to determine the present value of future lease payments. The
Company primarily uses its incremental borrowing rate adjusted to reflect a secured rate, based on the
information available for leases, including the lease term and interest rate environment in the country in
which the lease exists. The lease terms used to calculate the ROU asset and lease liability may include
options to extend or terminate when it is reasonably certain that the Company will exercise that option.

The Company leases office facilities under non-cancelable operating leases with terms generally ranging
between 10 and 25 years. The Company utilizes these leased office facilities for use by its employees in
countries in which the Company conducts its business. Leases are negotiated with third-parties and, in
some instances contain renewal, expansion and termination options. The Company also subleases
certain office facilities to third-parties when the Company no longer utilizes the space. None of the
Company’s leases restrict the payment of dividends or the incurrence of debt or additional lease
obligations, or contain significant purchase options. In addition to the base rental costs, the Company's
lease agreements generally provide for rent escalations resulting from increased assessments for real
estate taxes and other charges. A portion of our real estate lease portfolio contains base rents subject to
annual changes in the Consumer Price Index ("CPI") as well as charges for operating expenses which are
reimbursable to the landlord based on actual usage. Changes to the CPI and payments for such
reimbursable operating expenses are considered variable and are recognized as variable lease costs in
the period in which the obligation for those payments was incurred. Approximately 99% of the Company's
lease obligations are for the use of office space. All of the Company's material leases are operating
leases.

As a practical expedient, the Company has elected an accounting policy not to separate non-lease
components from lease components and instead account as a single lease component. The Company

108

has also elected not to recognize ROU assets and lease liabilities for leases that, at the commencement
date, are for 12 months or less.

The Company determined that $28 million and $9 million of its ROU assets were impaired, and therefore,
recorded a charge to the consolidated statement of income for the year ended December 31, 2020 and
2019, respectively, with an offsetting reduction to ROU assets.

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, 2020.

Senior Notes

In December 2020, the Company repaid $700 million of maturing Senior Notes. The Company also
prepaid $300 million of floating rate notes with an original maturity of December 2021.

110

In May 2020, the Company issued $750 million of 2.250% Senior Notes due 2030. The Company used
the net proceeds from this offering to pay outstanding borrowings under the revolving credit facility
discussed above.

In March 2020, the Company repaid $500 million of maturing Senior Notes.

In September 2019, the Company repaid $300 million of maturing senior notes.

During 2019, the Company issued approximately $6.5 billion of Senior Notes to primarily fund the
acquisition of JLT, including the payment of related fees and expenses, and to repay certain JLT
indebtedness, as well as for general corporate purposes.

In connection with the closing of the JLT Transaction, the Company assumed approximately $1 billion of
historical JLT indebtedness, which it repaid during 2019. The Company incurred debt extinguishment
costs of $32 million in regard to the repayment of this debt.

Other Credit Facilities

In January 2020, the Company closed on $500 million one-year and $500 million two-year term loan
facilities. In the first quarter of 2020 the Company borrowed $1 billion against these facilities. During the
third quarter of 2020, the Company repaid $500 million of borrowings from its one-year facility. In
December 2020, the Company repaid $500 million of borrowings from the two year facility. These two
facilities were terminated as of December 31, 2020 after repayment of the initial draw down.

In October 2018, the Company and certain of its foreign subsidiaries increased its multi-currency five-year
unsecured revolving credit facility from $1.5 billion to $1.8 billion. 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
October 2023 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, 2020. The
facility includes a provision for determining a LIBOR successor rate in the event LIBOR reference rates
are no longer available. In such case, the rate would be determined using an alternate reference rate that
has been broadly accepted by the syndicated loan market in the United States in lieu of LIBOR (the
“LIBOR successor rate”). If no LIBOR successor rate has been determined, the rate will be based on the
higher of the rate announced publicly by Citibank, New York, NY, as its base rate or the fed funds rate
plus a fixed margin.

In April 2020, the Company entered into a new 364 day $1 billion unsecured revolving credit facility with a
term out option after one year. The facility has similar coverage and leverage ratios as the multi-currency
five-year unsecured revolving credit facility. The Company had no borrowings outstanding under these
facilities at December 31, 2020.

Additional credit facilities, guarantees and letters of credit are maintained with various banks, primarily
related to operations located outside the United States, aggregating $573 million at December 31, 2020
and $598 million at December 31, 2019. There were no outstanding borrowings under these facilities at
December 31, 2020 and December 31, 2019.

Scheduled repayments of long-term debt in 2021 and in the four succeeding years are $517 million, $516
million, $619 million, $1.6 billion and $518 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 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.

Integration and Restructuring Costs

JLT Related Integration and Restructuring

The Company is completing its integration of JLT, which involves combining business practices and co-
locating colleagues in most geographies, rationalization of real estate leases around the world, realization
of synergies and migration of legacy JLT systems onto the Company's information technology
environment and security protocols. The Company also incurred costs for consulting fees related to
integration management processes and legal fees related to the rationalizing legal entity structures to
reduce costs, mitigate risks and improve operational transparency.

Costs recognized are based on applicable accounting guidance which includes accounting for disposal or
exit activities, guidance related to impairment of long lived assets (for right of use assets related to real
estate leases), as well as other costs resulting from accelerated depreciation or amortization of leasehold
improvements and other property and equipment. The Company has incurred $251 million in 2020 and
$335 million in 2019.

In connection with the JLT integration and restructuring, for the year ended December 31, 2020, the
Company incurred costs of $251 million: $171 million in RIS, $51 million in Consulting, $29 million in
Corporate. The severance and related costs were included in compensation and benefits and the other
costs were included in other operating expenses in the consolidated statement of income.

Details of the JLT integration and restructuring activity from January 1, 2019 through December 31, 2020,

Other Restructuring

During the fourth quarter of 2018, Mercer initiated a program to restructure its business to further optimize
the way Mercer operates, setting up the Company for a more fluid and nimble structure and operating
model for the future. The Company completed this initiative and incurred restructuring severance and
consulting costs of $54 million for the year ended December 31, 2020 related to this initiative.

In addition to the changes discussed above, the Company incurred costs of $32 million at Corporate for
the year ended December 31, 2020 that reflects costs to modernize the Company's information

112

technology systems and security protocols, consulting costs related to the restructure of the Global HR
function and adjustments to restructuring liabilities for future rent under non-cancellable leases.

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.

15. Common Stock

The Company did not repurchase any of its common stock during 2020. During 2019, the Company
repurchased 4.8 million shares of its common stock for total consideration of $485 million. In November
2019, 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 $2.4 billion.
There is no time limit on the authorization.

The Company issued approximately 4.1 million and 4.6 million shares related to stock compensation and
employee stock purchase plans during the years ended December 31, 2020 and 2019, respectively.

16. Claims, Lawsuits and Other Contingencies

Acquisition of Jardine Lloyd Thompson Group plc

On April 1, 2019, the Company completed its previously announced acquisition of all of the outstanding
shares of JLT. See Note 5 to the consolidated financial statements for additional information. Upon the
consummation of the acquisition of JLT, the Company assumed the legal liabilities and became
responsible for JLT’s litigation and regulatory exposures as of April 1, 2019.

Legal 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, 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.

114

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 offices of Marsh Limited, our Marsh and Guy Carpenter operating subsidiary
in the United Kingdom, and JLT Specialty Ltd., JLT's U.K. operating subsidiary. The FCA
indicated that it had reasonable grounds for suspecting that Marsh Limited, JLT Specialty
Ltd. and other participants in the market had 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 both Marsh and JLT, 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 and JLT
Specialty Ltd. that it had discontinued its investigation under U.K. competition law. In May
2018, the FCA advised that it would not be taking any further action with Marsh Limited or
JLT Specialty Ltd. in connection with this matter.

In November 2020, the Company received a notice that the European Commission
adopted a decision to close this investigation without taking any action.

In January 2019, the Company received a notice that the Administrative Council for
Economic Defense anti-trust agency in Brazil had commenced an administrative
proceeding against a number of insurance brokers, including both Marsh and JLT, and
insurers “to investigate an alleged sharing of sensitive commercial and competitive
confidential information" in the aviation insurance and reinsurance sector.

•

In 2017, JLT identified payments to a third-party introducer that had been directed to
unapproved bank accounts. These payments related to reinsurance placements made on
behalf of an Ecuadorian state-owned insurer between 2014 and 2017. In early 2018, JLT
voluntarily reported this matter to law enforcement authorities. In February and March
2020, money laundering charges were filed in the United States against a former
employee of JLT, the principals of the third-party introducer and a former official of the
state-owned insurer. Three of these individuals, including the former JLT employee, have
since pleaded guilty to criminal charges. We are cooperating with all ongoing
investigations related to this matter.

At this time, we are unable to predict the likely timing, outcome or ultimate impact of the foregoing
investigations or any related matters. 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.

Consulting Segment

In 2014, the FCA conducted an industry-wide review of the suitability of financial advice provided to
individuals by a number of companies, including JLT, relating to enhanced transfer value ("ETV") defined
benefit pension transfers. In January 2015, the FCA notified JLT that it was commissioning a Skilled
Person review of ETV pension transfer advice given by JLT and a business acquired by JLT in 2012.
Following the Skilled Person review which took place between 2015 and 2018, JLT engaged a
compliance consulting firm to conduct an analysis of approximately 14,000 individual files to assess the
suitability of the advice provided and, where appropriate, the amount of redress to be paid. In February
2019, prior to the completion of its acquisition by the Company, JLT recorded a gross liability of £59
million (or $77 million). This preliminary estimate by JLT, which reflected the projected redress amounts

115

contained in the Skilled Person report, was based on a review of a limited number of files. Thereafter, the
FCA expanded the scope of the thematic review. As of December 31, 2020, the updated redress liability,
including the projected costs of completing the review, increased to £155 million (or $210 million) resulting
from the expansion in the scope of the review, and the significant progress made in completing the
individual suitability reviews. We expect to finalize the suitability review of the limited number of files that
remain outstanding and calculate all redress amounts by the end of the second quarter of 2021. We
anticipate this gross liability will be partially offset by a contractual indemnity and insurance recoveries
from third-party E&O insurers.

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, 2020, 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 16 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.

17. Segment Information

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

▪

▪

Risk and Insurance Services, comprising insurance services (Marsh) and reinsurance services
(Guy Carpenter); and

Consulting, comprising Mercer and Oliver Wyman Group

The accounting policies of the segments are the same as those used for the consolidated financial
statements described in Note 1. Segment performance is evaluated based on segment operating income,
which includes directly related expenses, and charges or credits related to integration and restructuring
but not the Company’s corporate-level expenses. Revenues are attributed to geographic areas on the
basis of where the services are performed.

Prior to being acquired by the Company, JLT operated in three segments: Specialty, Reinsurance and
Employee Benefits. JLT operated in 41 countries, with significant revenue in the United Kingdom, Pacific,
Asia and the United States. As of April 1, 2019, the historical JLT businesses were combined into MMC

116

operations as follows: JLT Specialty is included by geography within Marsh, JLT Reinsurance is included
in Guy Carpenter and the majority of JLT's Employee Benefits business was included in Mercer Health
and Wealth.

Selected information about the Company’s segments and geographic areas of operation are as follows:

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, 2020 and 2019, the related consolidated
statements of income, comprehensive income, cash flows, and equity for each of the three years in the
period ended December 31, 2020, 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, 2020 and 2019, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 2020, 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, 2020, based on criteria established in Internal Control — Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 17,
2021, 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 a
reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the
financial statements that was communicated or required to be communicated to the audit committee and
that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our
especially challenging, subjective, or complex judgments. The communication of critical audit matters
does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by
communicating the critical audit matter below, providing a separate opinion on the critical audit matter or
on the accounts or disclosures to which it relates.

Liability for Errors and Omissions — Refer to Notes 1 and 16 to the financial statements

Critical Audit Matter Description

The Company is 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 (“E&O”)
in connection with the performance of professional services. These claims may seek damages, including
punitive and treble damages, in amounts that could be significant. The Company uses case level reviews
performed by inside and outside counsel, internal actuarial analysis and other methods to estimate
potential losses resulting from reported and unreported claims.

Given that the determination of the liability for E&O requires management to make significant estimates
and assumptions in projecting ultimate settlement values of reported and unreported claims, performing
audit procedures to evaluate the reasonableness of such estimates and assumptions required a high
degree of auditor judgment, including the need to involve our actuarial specialists.

119

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the determination of the liability for E&O included the following, among
others:

• We tested the effectiveness of internal controls related to the determination of the liability for
E&O, including controls over the projection of ultimate settlement values of reported and
unreported claims determined through internal actuarial analyses, management’s review of the
appropriateness of the assumptions used and calculation of case loss estimates, and
management’s independent review of case level estimates provided by inside and outside
counsel, as applicable.

•

For selected E&O matters, we evaluated the reasonableness of management’s case loss
estimates and, as applicable, made inquiries of the Company’s inside and outside counsel
regarding the status of these matters and likelihood of settlement.

• We compared total incurred losses and current case estimates as of the balance sheet date to
amounts reported in prior periods to evaluate trends and developments in reported cases.

• With the assistance of our actuarial specialists, we evaluated the reasonableness of the
assumptions and methodologies involved in the development of the liability for E&O by:

–

Testing the underlying data that served as the basis for the actuarial analysis, including
historical claims and case loss estimates, to evaluate whether the inputs to the actuarial
estimate were reasonable.

– Comparing management’s prior-year assumptions of expected development and ultimate loss

to actual amounts incurred during the current year to identify potential bias in the
determination of the liability for E&O.

– Developing a range of independent estimates and comparing those to the liability for E&O

recorded by the Company.

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, 2020 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, 2020.

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, 2020.

(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, 2020, 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, 2020, based on 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, 2020, of the Company and our report dated February 17, 2021, 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.

123

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.
