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 underwriting services and 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.

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. In certain circumstances, we are also required to maintain operating funds primarily related to regulatory requirements outside the U.S. See Part I, Item 1A ("Risk Factors") below for a discussion of how actions by regulatory authorities or changes in legislation and regulation in the jurisdictions in which we operate may have an adverse effect on our businesses.

Risk and Insurance Services.

While laws and regulations vary from location to location, every state of the United States and most foreign jurisdictions require insurance market intermediaries and related service providers (such as insurance brokers, agents and consultants, reinsurance brokers and managing general agents) to hold an individual or company license from a government agency or self-regulatory organization. Some jurisdictions issue licenses only to individual residents or locally-owned business entities; in those instances, if the Company has no licensed subsidiary, it may maintain arrangements with residents or business entities licensed to act in such jurisdiction. Such arrangements are subject to an internal review and approval process. Licensing of reinsurance intermediaries is generally less rigorous compared to that of insurance brokers, and most jurisdictions require only corporate reinsurance intermediary licenses.

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.

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 Marsh McLennan entities or 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 investment management responsibilities) and retirement and employee benefit program administrative services provided by Mercer and its subsidiaries and affiliates may also be subject to investment and securities regulations in various jurisdictions, including (but not limited to) 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. Depending on the nature of the client and services performed, Mercer may also be subject to direct oversight by the Departments of Health and Human Services and other federal agencies in the U.S. 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 and MMA certain client financial account obligations relating 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 sizes, the competitive landscape is complex and varies across 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 the 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 in every geography in which it operates, from insurance and reinsurance companies that market, distribute and service their insurance and reinsurance products without the assistance of brokers 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 as a supplement or alternative to purchasing 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 that compete with the Company's offerings.

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, broking and outsourcing firms, as well as consulting, broking and outsourcing operations affiliated with larger 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, Segment Information, in the notes to the consolidated financial statements included under Part II, Item 8 of this report.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG)

Since 2008, Marsh McLennan has had a framework for overseeing and managing the company's corporate responsibility initiatives at the Board and senior management levels. Consistent with our ESG philosophy, we believe our commitment to sustainability starts at home. We also believe that Marsh McLennan is well positioned to help our clients tackle the challenges of climate resilience. We are committed to developing innovative solutions to help move the world towards a more sustainable future. Our ESG Report discloses against aspects of the Task Force on Climate-related Financial Disclosures, Sustainability Accounting Standards Board and Global Reporting Initiative standards and describes the six UN Sustainable Development Goals we have prioritized that most relate to our business. Our ESG Report, Pay Equity Statement, statement on Human Rights and related information is available on our website at marshmclennan.com/about/esg.html. These reports and our website are not deemed part of this report and are not incorporated by reference.

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.marshmclennan.com/about/esg.html for our consolidated ESG Report. 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, 2021, the Company and its consolidated subsidiaries employed 83,000 colleagues worldwide, including approximately 48,800 in Risk and Insurance Services and 31,200 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, Latin America and the Middle East over the last several years. Women comprise more than half of our global enterprise workforce, and approximately 32% 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 16% 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 inclusion and diversity 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 inclusion and diversity 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.

Inclusion & Diversity.

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. We have a Race Advisory Council to advise our Executive Committee and help amplify diverse perspectives in decision-making. Other initiatives included learning and sponsorship programs 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 goals, performance, career aspirations and development opportunities. We also recognize the importance of our 14,000 people managers to our talent pipeline and have given them increased support and opportunities for promoting the growth of their teams. In 2021 we offered nearly 400 live learning sessions in addition to more than 32,000 individual learning courses to help our colleagues grow and develop. We also launched an updated People Manager Hub, a one-stop source for people managers globally. Through the Hub, people managers have access to suggested learning, webinars and resources to support development and provide guidance for leading with clarity and inclusion.

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. In 2021, we expanded questions on health and well-being, inclusion and diversity, and ethics and integrity. A third-party administers our survey in order to maintain confidentiality of responses. Collective survey outcomes allow us to identify opportunities and monitor the evolution of our culture over time.

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% 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 changing circumstances-health and economic challenges, new technologies and social inequities-has been our priority in 2021.

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 people in roles that have a significant impact on our long-term performance and success. Our offerings also include retirement benefits, savings and stock investment plans in certain jurisdictions.

RISKS RELATING TO THE COMPANY GENERALLY

Cybersecurity, Data Protection and Technology Risks

We could incur significant liability or our reputation could be damaged if our information systems are breached or we otherwise fail to protect client or Company data or information systems.

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, through use of increasingly sophisticated methods of attack, including the deployment of artificial intelligence to find and exploit vulnerabilities, such as "deep fakes", long-term, persistent attacks referred to as advanced persistent threats and the use of the IT supply chain to introduce malware through software updates or compromised suppliers accounts or hardware. In particular, we are at increased risk of a cyberattack when geopolitical tensions are high, as diplomatic events and economic policies may trigger espionage or retaliatory cyber incidents.

The 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 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. Highly publicized data security breaches, such as the December 2020 large-scale attack on SolarWinds that created security vulnerabilities for public and private organizations around the world may embolden malicious actors to target the IT supply chain and providers of business software. While we do not believe our operations were affected by the SolarWinds attack, other similar supply chain compromises could have a significant negative impact on our systems and operations.

We have a history of making acquisitions and investments, including the acquisition of JLT in 2019. 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 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 experienced data incidents and cybersecurity breaches, such as malware incursions (including computer viruses and ransomware), vulnerabilities in the software on which we rely, 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. In April 2021, an unauthorized actor leveraged a vulnerability in a third party's software and gained access to a limited set of data in our environment. Like many companies, we are also subject to social engineering attacks such as WhatsApp scams and regular phishing email campaigns directed at our employees that can result in malware infections, fraud 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. A cyber attack may also result in systems or data being encrypted or otherwise unavailable due to ransomware or other malware. 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 collection, use disclosure, cross border transfer, and retention 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, we store and transfer sensitive employee and client data, including personal data, in and across multiple jurisdictions. We collect data from client and individuals located all over the world and leverage systems and teams to process it. 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 U.S. and E.U and between the United Kingdom and the E.U., 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 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 enacted the Personal Information Protection Law a new comprehensive privacy law, India is considering a new privacy law, Canada is proposing significant changes to its 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.

In the U.S. following the passage of the CCPA, California approved a ballot measure that enacts the California Privacy Rights Act, which makes extensive modifications to the CCPA. Additionally, several other states have introduced privacy bills, some more comprehensive than or divergent in key respects from the CCPA. There is also continued legislative interest in passing a federal privacy law.

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. A number of states have also adopted laws covering data collected by insurance licensees that include security and breach notification requirements. 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 use 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.

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 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 (Al), 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.

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, investment management 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 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 Belarus, Cuba, Crimea, Iran, Myanmar, 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 addition, the financial and operational impact of complying with laws and regulations has increased in the current environment of increased regulatory activity and enforcement. Changes with respect to the applicable laws and regulations may impose additional and unforeseen costs on us or pose new or previously immaterial risks to us. There can be no assurance that current and future government regulations will not adversely affect our business, and we cannot predict new regulatory priorities, the form, content or timing of regulatory actions, and their impact on our business and operations.

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. Additional information regarding certain ongoing investigations and certain other legal and regulatory proceedings is set forth in Note 16, Claims, Lawsuits and Other Contingencies, in the notes to the 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, or our efforts to attract and retain talent, 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. We may be unable to retain them, particularly if we do not offer employment terms that are competitive with the rest of the labor market. 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, which has accelerated through the pandemic. Such challenges include the general mobility of colleagues that has increased as a result of the COVID-19 pandemic as companies experiment with more flexible working models, market dislocation resulting from proposed and actual combinations in the industry, and fostering an inclusive and diverse workplace.

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. 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. If a colleague joins us from a competitor and is subject to enforceable restrictive covenants, we may not be able to secure client engagements or maximize the colleague's potential.

Over the course of 2021, we hired on a net basis more than 6,000 colleagues across our company. As a result, our expenses have increased.

Failure to maintain our corporate culture, particularly in a hybrid work environment, 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 an inclusive and diverse 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. Remote and hybrid work arrangement as a result of the COVID-19 pandemic may also negatively impact our ability to maintain and promote our culture, as we believe being together is integral to promoting our culture.

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, inclusion and diversity, racial justice, pay equity, workplace conduct, cybersecurity and data privacy. 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 accurately report or 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, exclusion of our stock from ESG-oriented indices or investment funds or harm our relationships with regulators and the communities in which we operate.

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. Additionally, the competition for talent has only accelerated with the COVID-19 pandemic and recent dislocation in the market resulting from proposed and actual combinations among our competitors. If we are unable to attract, retain and fully develop industry leading talent, or 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 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 which 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 certain subsegments, we compete in highly fragmented markets or with start-ups that may be able to offer solutions at a lower price or on more favorable conditions.

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 control many of 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.

Macroeconomic Risks

The COVID-19 pandemic has impacted how we work, and the extent to which it will continue to do so and its impact on our future financial results are uncertain.

Global health concerns relating to the ongoing COVID-19 pandemic and related government actions taken to reduce the spread of the virus impacted 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 continuing to operate in a largely remote model as the pandemic has persisted across the globe, introducing vaccine mandates for certain U.S. colleagues or visitors to be on premises where legally viable to do so, and re-calibrating return-to-office plans with evolving health and safety standards). We will continue to evolve our business practices as we adopt hybrid working arrangements and evaluate further implementing employee vaccine requirements and other health and safety protocols, 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 in creating an effective and productive working environment comparable to pre-pandemic conditions for our colleagues. In addition, our implementation of employee vaccination requirements may also result in attrition, including of critically skilled colleagues.

Our results of operations and investments could be adversely affected by macroeconomic conditions, political events and market conditions.

Macroeconomic conditions, including inflation, supply chain challenges, pandemics, a general slowdown in economic growth, political volatility and other market conditions around the world affect our clients' businesses and the markets they serve. These conditions, including inflationary expense pressure with our clients, may reduce demand for our services or depress pricing for those services, which could have a material adverse effect on our results of operations. For example, in 2020 the COVID-19 pandemic adversely impacted the Company's revenue growth, primarily in our businesses that are discretionary in nature. 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 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. As the terms of the withdrawal did not contain resolutions related to financial services and there has not yet been such an agreement, there remains uncertainty on the effect of Brexit on financial services.

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 or disrupt markets we serve, affecting our operations and business or causing 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 E.U. 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. 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.

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 approximately 3,300 and 5,300 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.

Global health concerns relating to the ongoing COVID-19 pandemic and related government actions taken to reduce the spread of the virus have impacted our workforce and operations and the operations of our clients, third-party vendors and business partners, and could in the future materially adversely impact our business, operations and financial results. The spread of COVID-19 has caused us to take a number of steps to safeguard our business and colleagues from COVID-19, including implementing travel restrictions, arranging work from home capabilities and transitioning to a hybrid work environment. While the Company expects it will continue to service clients effectively in a remote or hybrid work environment, 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 that of new variants, the availability and efficacy of treatments and vaccines, and how quickly and to what extent pre-pandemic economic and operating conditions resume. In addition, as we prepare to return our workforce in more locations back to the office in 2022, we may experience increased costs as we prepare our facilities for a safe return to work environment and experiment with hybrid work models.

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 84 in the period from 2016 to 2021. 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, 2021, our receivables for our commissions and fees were approximately $5.1 billion, or approximately one-quarter of our total annual revenues, and portions of our receivables are increasingly concentrated in certain businesses and geographies.

Macroeconomic or political conditions, such as the impact from COVID-19, inflationary pressures or supply chain challenges, 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. There can be no assurance that our operations will generate sufficient positive cash flow to finance all of our capital needs or that we will be able to obtain equity or debt financing on favorable terms. In addition, our ability to obtain financing will depend in part upon prevailing conditions in credit and capital markets, which are beyond our control.

Our defined benefit pension plan obligations could cause the Company's financial position, earnings and cash flows to fluctuate.

Our defined benefit pension obligations and the assets set aside to fund those obligations are sensitive to certain changes in the financial markets. Any such changes may result in increased pension expense or additional cash payments to fund these plans.

The Company has significant defined benefit pension obligations to its current and former employees, totaling approximately $18.7 billion, and related plan assets of approximately $19.4 billion, at December 31, 2021 on a U.S. GAAP basis. The Company's policy for funding its defined benefit pension plans is to contribute amounts at least sufficient to meet the funding requirements set forth by law. In the United States, contributions to these plans are based on ERISA guidelines. Outside the United States, contributions are generally based on statutory requirements and local funding practices, which may differ from measurements under U.S. GAAP. In the U.K., for example, the assumptions used to determine pension contributions are the result of legally-prescribed negotiations between the Company and the plan 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 and liabilities, 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.

Approximately 53% of our total revenue reported in 2021 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 capacity and utilization rates and clients' ability to terminate engagements without penalty;
•	our net colleague hires and related compensation and benefits expense;
•	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 as a result of increased regulatory activity and enforcement;
•	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, advisement or administration; and
•	general economic conditions, including factors beyond our control affecting economic conditions such as COVID-19 and other global health crises 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 Baal by Moody's. The Company carries a Stable outlook with both S&P and 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. A downgrade to a rating below investment-grade could result in greater operational risks through increased operating costs and increased competitive pressures.

Our current debt level could adversely affect our financial flexibility.

As of December 31, 2021, we had total consolidated debt outstanding of approximately $11.0 billion.

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 and the continuing issuance of interpretive guidance related to the operations of U.S.-based multinational corporations. These include 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 expense, 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, changes under consideration to the current U.S. tax regime, including to the GILTI minimum tax, further limitations on interest expense deductibility, and a book minimum tax, could 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 2021, 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. In addition, we conduct our operations through four separate businesses. Potential conflicts of interest may arise across our businesses given the significant volume of our engagements.

The geographic breadth of our activities also 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 upcoming changes to the U.K. statutory rate and international initiatives to require multinational enterprises, like ours, to calculate and report profitability on a country-by-country basis, which could increase scrutiny by, or cause disagreements with, foreign tax authorities and the uncertainty around the implementation of the new global minimum tax the framework of which was agreed by the members of the Organization for Economic Cooperation and Development in late 2021;
•	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;
•	permanent establishments created due to colleagues traveling to and doing work in countries where the company has no presence, or living in such countries and working remotely postpandemic, 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;
•	international hostilities, international trade disputes, geopolitical tensions in countries in which we operate, 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 Belarus, Cuba, Crimea, Iran, Myanmar, 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 61 % of the Company's total revenue in 2021. 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 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 Insurance 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 6% of Marsh's revenue in 2021. This other compensation includes payment for (i) consulting and analytics services provided to insurers; (ii) administrative and other services provided to insurers (including underwriting services and 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 39% of our total revenue in 2021. 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 market fluctuations, third-party asset managers, operational and technology risks, 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 digital tools, investment consulting and investment management services. As of December 31, 2021, Mercer and its global affiliates had assets under management of approximately $415 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 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, (particularly as we increasingly act in a fiduciary capacity), liquidity and market volatility, third-parties, our operations and technology, 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 or timely implement a client's investment policy or direction, which could cause an incorrect or untimely allocation of client assets among asset classes, 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 or due to other perceived conflicts of interest. Asset classes may perform poorly, or asset managers may underperform their benchmarks, due to poor market performance, a downturn in the global markets, negligence or other reasons, resulting in poor returns or loss of client assets. Changes in the value of equity, debt, currency real estate, commodities, alternatives or other asset classes, in particular as a result of a downturn in the global markets, could cause the value of our assets under management or advisement, and the fees earned by Mercer 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, alternatives 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 plan sponsors, plan trustees, multi-employer and public entity 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 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, fee compression pressures, and a continued or accelerated 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 and contingent 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. Mercer's consulting services involve the drafting and interpretation of trust deeds and other complex documentation governing pension plans. Mercer's administration services include calculating benefits within complicated pension plan structures. Mercer's 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 revenues, profit margin and profitability could decline.

In addition, the profitability of our Consulting businesses depends in part on the prices we are able to charge for our services. The prices we charge are affected by a number of factors, including:

•	clients' perception of our ability to add value through our services;
•	market demand for the services we provide;
•	our ability to develop new services and the introduction of new services by competitors;
•	the pricing policies of our competitors;
•	the extent to which our clients develop in-house or other capabilities to perform the services that they might otherwise purchase from us; and
•	general economic conditions.

If we are unable to achieve and maintain adequate billing rates for our services, our profit margin and profitability could decline.

Item 1B. Unresolved Staff Comments.

There are no unresolved comments to be reported pursuant to Item 1B.

Item 2. Properties.

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, Claims, Lawsuits and Other Contingencies, in the notes to the consolidated financial statements appearing under Part II, Item 8 ("Financial Statements and Supplementary Data") of this report.

Item 4. Mine Safety Disclosures.

Business Update Related To COVID-19

The World Health Organization declared COVID-19 a pandemic in March 2020. For almost two years, the pandemic has impacted businesses globally including virtually every geography in which the Company operates. Our businesses have been resilient throughout the pandemic and demand for our advice and services remains strong as the global economic conditions continue to improve.

Although the majority of our colleagues continue to work remotely, the Company has provided guidelines on return to the office depending on the level of virus containment and local health and safety regulations in each geography. The safety and well-being of our colleagues is paramount and the Company expects to continue to service clients effectively in both the remote and in-office environments.

The Company had strong revenue growth in 2021 and benefited from the continued recovery of the global economy. However, uncertainty remains in the economic outlook and the ultimate extent of the impact of COVID-19 to the Company will depend on future developments that it is unable to predict, including new "waves" of infection from emerging variants of the virus, potential renewed restrictions and mandates by various governments or agencies, and the distribution and uptake of vaccines and vaccine boosters.

Acquisition of JLT

On April 1, 2019, the Company completed the acquisition (the "Transaction") of all of the outstanding shares of JLT, a public company organized under the laws of England and Wales. As of December 31, 2021, 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 Note 16, Claims, Lawsuits and Other Contingencies, in the notes 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. JLT's results of operations for the period January 1 through March 31, 2019 are not included in the Company's results of operations and therefore, affect comparability. The Company's results for the years ended December 31, 2021, 2020 and 2019 were impacted by JLT related acquisition restructuring and integration costs as discussed in Note 14, Integration and Restructuring Costs, in the notes to the consolidated financial statements.

Consolidated operating income increased $1.2 billion, or 41% to $4.3 billion in 2021 compared to $3.1 billion in 2020, reflecting a 15% increase in revenue and a 10% increase in expenses. Revenue growth was driven by increases in the Risk and Insurance Services and Consulting segments of 17% and 12%, respectively, reflecting the strong demand for our advice and services and the improvement in global economic conditions. The increase in expense is primarily due to increased headcount and higher incentive compensation. These increases were partially offset by a reduction in JLT integration costs and the JLT legacy E&O provision recorded in 2020.

Diluted earnings per share increased 56% to $6.13 in 2021 compared with $3.94 in 2020. The increase is a result of higher operating income, lower interest expense and higher investment gains in 2021 compared to 2020. Results in 2021 also include a net charge of approximately $110 million related to the re-measurement of deferred tax assets and liabilities due to the enactment of a tax rate increase from 19% to 25% in the U.K. in the second quarter of 2021, offset by no tax impact on the gain from the remeasurement to fair value upon consolidation of the Company's previously held equity method investment in India, tax benefits from share-based compensation and planning that included the utilization of foreign tax credits and postponing the utilization of the losses in the U.K. to a future year when the tax rate will be 25%.

The following table summarizes restructuring and other items discussed in more detail below:

Impact on operating income	$ (22)	$ 578	$ 674

In 2021 and 2020, the Company's results of operations and earnings per share were impacted by 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, Integration and Restructuring, in the notes to the consolidated financial statements.
•	Changes in contingent consideration: Primarily includes the change in fair value of contingent consideration related to acquisitions and dispositions as measured each quarter.
•	JLT integration and restructuring costs: Includes severance, real estate and technology rationalization, process management consulting fees, and legal fees for the rationalization of legal entity structures. The Company has incurred JLT integration and restructuring costs of $679 million through 2021 and expects to incur the remaining $46 million in 2022, primarily related to real estate and technology, of which approximately $42 million will be cash expenditures. The Company has realized at least $425 million of annualized savings. These costs are discussed in more detail in Note 14, Integration and Restructuring, in the notes to the consolidated financial statements. The Company expects to complete the integration of JLT during 2022.
•	JLT acquisition-related costs and other: Includes retention and legal charges related to the acquisition of JLT.
•	JLT legacy E&O provision: In 2021, the Company recorded a $36 million reduction in the liability as well as $33 million of recoveries under indemnities for a legacy JLT Errors and Omissions ("E&O") provision relating to suitability of financial advice provided to individuals for defined benefit pension transfers. The reduction in liability primarily reflects lower redress payments than previously estimated, partly offset by higher costs to review and calculate redress. In 2020, the Company recorded an increase in the liability of $161 million related to this matter. See Note 16, Claims, Lawsuits and Other Contingencies, in the notes to the consolidated financial statements.
•	Legal claims: The Company recorded settlement charges and legal costs related to strategic recruiting.
•	Gain on consolidation of business: In December 2021, the Company increased its ownership in Marsh India from 49% to 92%. Prior to the increase in ownership, the Company accounted for the investment under the equity method of accounting. In connection with the increased investment in Marsh India, the Company recorded a gain of $267 million, related to the remeasurement of its previously held investment to fair value.
•	Disposal of businesses: During 2021, the Company disposed of certain businesses and recognized a net gain of approximately $50 million, primarily related to the commercial networks business in the U.K. that provided broking and back-office solutions for small independent brokers. Results in 2020 include a contingent gain adjustment from the U.S. large market health and defined benefit administration business disposed in 2019.

Consolidated Revenue and Expense

Revenue - Components of Change

The Company conducts business in 130 countries. As a result, foreign exchange rate movements may impact period-to-period comparisons of revenue. Similarly, certain other items such as the revenue impact of acquisitions and dispositions, including transfers among businesses, may impact period-to-period comparisons of revenue. Underlying revenue measures the change in revenue from one period to another by isolating these impacts.

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

Consolidated Revenue

Consolidated revenue increased $2.6 billion, or 15%, to $19.8 billion in 2021, compared to $17.2 billion in 2020. Consolidated revenue increased 10% on an underlying basis, 2% from the impact of foreign currency translation and 3% from acquisitions. On an underlying basis, revenue increased 10% for the year ended December 31, 2021 in both the Risk and Insurance Services and Consulting segments.

Underlying growth in the Risk and Insurance Services and Consulting segments was driven by the strong demand for our advice and services and the improvement in global economic conditions.

Consolidated Operating Expense

Consolidated operating expenses increased $1.3 billion, or 10%, to $15.5 billion in 2021 compared to $14.2 billion in 2020, reflecting increases of 6% on an underlying basis, 2% from the impact of foreign currency translation and 1% from acquisitions. On an underlying basis, expenses increased 8% and 3% in 2021 in the Risk and Insurance Services and Consulting segments, respectively. Underlying expenses in 2021 is primarily due to increased headcount and higher incentive compensation.

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 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. Revenues can be affected by premium rate levels in the insurance/reinsurance markets, the amount of risk retained by insurance and reinsurance clients 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 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.

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, payment for consulting and analytics services provided to insurers; compensation for administrative and other services (including fees for underwriting services and 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. 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 previous revenue by segments tables.

The results of operations for the Risk and Insurance Services segment are presented below:

(In millions, except percentages)	2021	2020	2019
Revenue	$ 12,085	$ 10,337	$ 9,599
Compensation and benefits	6,506	5,690	5,370
Other operating expenses	2,499	2,301	2,396
Operating expenses	9,005	7,991	7,766
Operating income	$ 3,080	$ 2,346	$ 1,833
Operating income margin	25.5 %	22.7 %	19.1 %

Revenue

Revenue in the Risk and Insurance Services segment increased $1.7 billion, or 17%, to $12.1 billion in 2021 compared with $10.3 billion in 2020. Revenue grew 10% on an underlying basis, 5% from the impact of acquisitions, and 2% related to the impact of foreign currency translation. The increase in underlying revenue was primarily due to strong growth in new business, solid retention, and benefits from pricing in the marketplace.

In Marsh, revenue increased $1.6 billion, or 19%, to $10.2 billion in 2021 compared to $8.6 billion in 2020. This reflects increases of 11% on an underlying basis, 6% from the impact of acquisitions, and 2% from the impact of foreign currency translation. In 2021, the increase in revenue from acquisitions reflects the gain of $267 million related to the re-measurement of the previously held equity method investment in Marsh India. On an underlying basis, U.S./Canada rose 13%. Total International operations, which includes Asia Pacific, Latin America and EMEA each produced underlying revenue growth of 9% compared to prior year.

At Guy Carpenter, revenue increased $171 million, or 10%, to $1.9 billion in 2021 compared with $1.7 billion in 2020. On an underlying basis, revenue increased 9%.

The Risk and Insurance Services segment completed eight acquisitions during 2021. Information regarding those acquisitions is included in Note 5, Acquisitions and Dispositions, in the notes to the consolidated financial statements.

Operating Expense

Expense in the Risk and Insurance Services segment increased $1.0 billion, or 13%, to $9.0 billion in 2021 compared with $8.0 billion in 2020. This reflects increases of 8% on an underlying basis, 2% from the impact of foreign currency, and 2% from acquisitions. The increase in underlying expense reflects increased headcount and higher incentive compensation, partly offset by lower JLT integration and restructuring costs.

Consulting

The Company conducts business in its Consulting segment through Mercer and Oliver Wyman Group. Mercer delivers advice and solutions that help organizations create a dynamic world of work, shape retirement and investment outcomes, and unlock health and well being for a changing workforce. Oliver Wyman serves as critical strategic, economic and brand advisor to private sector and governmental clients.

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. For a majority of the Mercer managed investment funds, revenue is recorded on a gross basis with sub-advisor fees included in other operating expenses.

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 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.

The results of operations for the Consulting segment are presented below:

(In millions, except percentages)	2021	2020	2019
Revenue	$ 7,789	$ 6,976	$ 7,143
Compensation and benefits	4,435	3,995	3,934
Other operating expenses	1,850	1,987	1,999
Operating expenses	6,285	5,982	5,933
Operating income	$ 1,504	$ 994	$ 1,210
Operating income margin	19.3 %	14.3 %	16.9 %

Revenue

Consulting revenue increased $813 million, or 12%, to $7.8 billion in 2021 compared with $7.0 billion in 2020. This reflects increases of 10% on an underlying basis and 3% from the impact of foreign currency translation.

Mercer's revenue increased $326 million, or 7%, to $5.3 billion in 2021 compared to $4.9 billion in 2020, or 5% on an underlying basis. Revenue also reflects an increase of 3% from the impact of foreign currency translation offset by a decrease of 1% from disposition of businesses. On an underlying basis, revenue for Career, Wealth and Health increased 12%, 4% and 3%, respectively. The increase in underlying revenue at Mercer for the year ended December 31, 2021 was due to higher investment management fees from growth in assets under management and increased demand and retention for Health and Career products and services.

Oliver Wyman Group's revenue increased $487 million, or 24%, to $2.5 billion in 2021 compared with $2.0 billion in 2020, reflecting an increase of 21% on an underlying basis and 2% from the impact of foreign currency translation. The increase in underlying revenue at Oliver Wyman for the year ended December 31, 2021 primarily reflects the impact of increased demand for project-based services across all industries.

The Consulting segment completed one acquisition during 2021. Information regarding the acquisition is included in Note 5, Acquisitions and Dispositions, in the notes to the consolidated financial statements.

Operating Expense

Consulting expenses increased $303 million, or 5%, to $6.3 billion in 2021 compared to $6.0 billion in 2020. This reflects an increase of 3% on an underlying basis and 2% from the impact of foreign currency translation. The increase in underlying expense in the Consulting segment in 2021 is primarily due to increased headcount and higher incentive compensation. This is partially offset by a $69 million reduction in the legacy JLT E&O provision including recoveries under indemnities. In 2020, the Company recorded an increase in the liability of $161 million for the same matter.

Corporate and Other

Corporate expense in 2021 was $272 million compared with $274 million in 2020. Expenses decreased 1% on an underlying basis due to lower integration and restructuring costs primarily related to the JLT Transaction and savings realized from the completion of integration efforts to date, partly offset by higher headcount and incentive compensation.

Other Corporate Items

Interest

Interest expense decreased $71 million to $444 million in 2021 compared to $515 million in 2020 due to lower average debt levels in 2021 compared to the prior year.

Investment Income (Loss)

The caption "Investment income (loss)" 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 private equity funds.

The Company recorded net investment income of $61 million in 2021 compared to a net investment loss of $22 million in 2020. The income in 2021 is primarily driven by gains in the Company's private equity investments. The loss in 2020 was primarily due to a loss from the sale of shares of Alexander Forbes ("AF").

Income Taxes

The Company's consolidated effective tax rate was 24.6% and 26.7% in 2021 and 2020, respectively. The rates in all periods reflect the effects of tax planning and the impact of regulatory and other guidance as it became available.

The rate for the year ended December 31, 2021 reflects:

•	The charge for re-measuring the Company's U.K. deferred tax assets and liabilities upon the enactment of legislation on June 10, 2021, commonly referred to as the "Finance Act 2021 The legislation increased the U.K. corporate income tax rate from 19% to 25% effective April 1, 2023. This is the most significant discrete item in the year-to-date period, increasing the Company's effective tax rate by 2.6% for the year ended December 31, 2021.
•	The tax effect of the gain from the fair value re-measurement of the Company's previously held equity method investment in Marsh India upon the Company increasing its ownership interest from 49% to 92%. The Company has indefinitely reinvested this gain, as it has no intent to dispose of the business, and did not record tax on the gain. This decreased the Company's effective tax rate by 1.5% for the year ended December 31, 2021.
•	Tax benefits from planning implemented in the period that postponed the utilization of losses in the U.K. to a future year when the tax rate will be 25%.

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 rate in 2020 also reflects costs of re-measuring the Company's U.K. deferred tax assets and liabilities upon the enactment of legislation that cancelled a 2% reduction in the U.K. corporate income tax rate, partially offset by tax benefits for the implementation of a new international funding structure to facilitate global staffing and contracting.

The tax rates in all periods reflect the impact of discrete tax matters such as excess tax benefits related to share-based compensation, enacted tax legislation, changes in uncertain tax positions, deferred tax adjustments and non-taxable 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 of earnings and repatriation of the Company's earnings, which may result in higher or lower tax rates. In 2021, pre-tax income in the U.K., Barbados, Canada, Ireland, Bermuda, and Australia accounted for approximately 60% of the Company's total non-U.S. pre-tax income, with effective rates in those countries of 21% (excluding the non-cash deferred tax impact of U.K. tax legislation enacted in 2021), 1%, 27%, 17%, 0.3% and 16%, 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 assets to the amount that the Company believes is more likely than not to be realized. Details are provided in Note 7, Income Taxes, in the notes to 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, the Company deferred payroll taxes due from March 27, 2020 through December 31, 2020 and paid 50% in 2021 and will pay the remaining 50% in 2022.

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, 2021, the Company had approximately $737 million of cash and cash equivalents in its foreign operations, which includes $280 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.

During 2021, the Company recorded foreign currency translation adjustments which decreased net equity by $389 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 and cash equivalents on our consolidated balance sheets includes funds available for general corporate purposes. Funds held on behalf of clients in a fiduciary capacity are segregated and shown separately in the consolidated balance sheets as an offset to fiduciary liabilities. Fiduciary funds cannot be used for general corporate purposes, and should not be considered as a source of liquidity for the Company.

Operating Cash Flows

The Company generated $3.5 billion of cash from operations in 2021 and $3.4 billion in 2020. 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 2021, the Company contributed $35 million to its U.S. pension plans and $95 million to non-U.S. pension plans compared to contributions of $65 million to U.S. plans and $78 million to non-U.S. plans in 2020.

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 2021, the Company made $30 million of contributions to nonqualified plans and $5 million to its qualified plans. The Company expects to contribute approximately $31 million to its non-qualified U.S. pension plans in 2022. The Company is not required to make any contributions to its U.S. qualified plan in 2022.

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, 2021. 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.

The Company contributed $55 million to its U.K. plans in 2021. The Company's contributions to its U.K. plans in 2022 are expected to be approximately $124 million.

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.

During 2021, the JLT Pension Scheme was merged into the MMC U.K. Pension Fund with a new segregated JLT section created. The Company made deficit contributions of $38 million to the JLT section in 2021 and is expected to make contributions totaling approximately $112 million in 2022. The funding level of the JLT section will be reassessed during 2022 to determine contributions in 2023 and onwards.

For the MMC U.K. Pension Fund, excluding the JLT section, an agreement was reached with the trustee in 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 as part of the December 31,2021 actuarial valuation 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 £450 million over a seven-year period.

In the aggregate, the Company expects to contribute approximately $147 million to its non-U.S. defined benefit plans in 2022, comprising approximately $124 million to the U.K. plans and $23 million to plans outside of the U.K.

Changes in Funded Status and Expense

The year-over-year change in the funded status of the Company's pension plans is impacted by the difference between actual and assumed results, particularly with regard to return on assets, and changes in the discount rate, as well as the amount of Company contributions, if any. Unrecognized actuarial losses were approximately $1.8 billion and $2.9 billion at December 31, 2021 for the U.S. plans and non U.S. plans, respectively, compared with losses of $2.4 billion and $3.5 billion at December 31, 2020. The decreases in both the U.S. and non-U.S. plans were primarily due to an increase in the discount rate used to measure plan liabilities and 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 2021 increased in the U.S. and U.K., the Company's largest plans, following decreases in 2020 and 2019. 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 2021, the Company's defined benefit pension plan assets had gains of 13.2% and 1.9% in the U.S. and U.K., respectively, as compared to gains of 13.1% and 12.0% in the U.S. and U.K., respectively, in 2020.

Overall, based on the measurement at December 31, 2021, net benefit credits related to the Company's defined benefit plans are expected to decrease in 2022 by approximately $23 million compared to 2021, reflecting a decrease in non-U.S. plans of approximately $40 million, offset by an increase in U.S. plans of $17 million.

The Company's accounting policies for its defined benefit pension plans, including the selection of and sensitivity to assumptions, are discussed in Management's Discussion of Critical Accounting Policies. For additional information regarding the Company's retirement plans, see Note 1, Summary of Significant Accounting Policies, and Note 8, Retirement Benefits, in the notes to the consolidated financial statements.

Financing Cash Flows

Net cash used for financing activities was $1.3 billion in 2021 compared with $925 million used by financing activities in 2020.

Credit Facilities

On April 2, 2021, the Company entered into an amended and restated multi-currency unsecured $2.8 billion five-year revolving credit facility ("New Facility"). The interest rate on the New Facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. The New Facility expires in April 2026 and requires the Company to maintain certain coverage and leverage ratios which are tested quarterly. The New Facility includes provisions for determining a LIBOR successor rate in the event LIBOR reference rates are no longer available or in certain other circumstances which are determined to make using an alternative rate desirable. As of December 31, 2021, the Company had no borrowings under this facility. In connection with the New Facility, the Company terminated its previous multicurrency unsecured $1.8 billion five-year revolving credit facility and its unsecured $1.0 billion 364-day unsecured revolving credit facility.

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. During 2020, the Company borrowed and repaid $1.0 billion against these facilities. These two facilities were terminated as of December 31, 2020 after repayment of the initial draw down.

The Company also maintains other credit facilities, guarantees and letters of credit with various banks, aggregating $508 million at December 31, 2021 and $573 million at December 31, 2020. There were no outstanding borrowings under these facilities as of December 31, 2021 or as of December 31, 2020.

Debt

On April 9, 2021, the Company increased its short-term commercial paper financing program to $2.0 billion from $1.5 billion. The Company had no commercial paper outstanding at December 31, 2021.

In December 2021, the Company issued $400 million of 2.375% senior notes due 2031 and $350 million of 2.90% senior notes due 2051. The Company used the net proceeds from these issuances for general corporate purposes and repaid $500 million of 2.75% senior notes with an original maturity date of January 2022 in December 2021.

On April 15, 2021, the Company repaid $500 million of senior notes maturing in July 2021.

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.

The Company's senior debt is currently rated A- by Standard & Poor's and Baal 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 both Standard & Poor's and Moody's.

Share Repurchases

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. During 2021, the Company repurchased 7.9 million shares of its common stock for total consideration of approximately $1.2 billion. As of December 31, 2021, the Company remained authorized to purchase shares of its common stock up to a value of approximately $1.3 billion. There is no time limit on this authorization.

The Company did not repurchase any of its common stock during 2020.

Dividends

The Company paid total dividends of $1.0 billion in 2021 ($2.00 per share) and $943 million in 2020 ($1.84 per share).

Contingent Payments Related To Acquisitions

The classification of contingent consideration payments in the consolidated statement of cash flows is dependent upon whether the receipt, payment, or adjustment 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 operating and financing activities:

For the Years Ended December 31,
(In millions)	2021	2020	2019
Operating:
Contingent consideration payments	$ (49)	$ (48)	$ (41)
Prior years' dispositions cash received	19	-	-
Acquisition related net charge for adjustments	57	26	68
Adjustments and payments related to contingent consideration	$ 27	$ (22)	$ 27
Financing:
Contingent purchase consideration	$ (28)	$ (54)	$ (22)
Deferred purchase consideration related to prior years' acquisitions	(89)	(68)	(43)
Payments of deferred and contingent consideration for acquisitions	$ (117)	$ (122)	$ (65)
Receipt of contingent consideration related to prior years' dispositions	$ 71	$ -	$ -

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 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 decreased by $100 million during 2021 related to the change in foreign exchange rates. The Company concluded that the hedge was highly effective and recorded a decrease to accumulated other comprehensive loss for the year ended December 31, 2021.

Fiduciary Liabilities

Since cash and cash equivalents held in a fiduciary capacity are not available for corporate use, they are shown in the consolidated balance sheet as an offset to fiduciary liabilities. Financing cash flows reflect an increase of $1.2 billion and $955 million in 2021 and 2020, respectively, related to the increase in fiduciary liabilities.

Investing Cash Flows

Net cash used for investing activities amounted to $1.2 billion in 2021 compared with $793 million used for investing activities in 2020.

The Company paid $859 million and $647 million, net of cash, cash equivalents and cash and cash equivalents held in a fiduciary capacity acquired, for acquisitions it made during 2021 and 2020, respectively, including the Company's increased ownership interest in Marsh India from 49% to 92% in December 2021.

During 2021 and 2020, the Company sold certain businesses, primarily in the U.S. and U.K., for cash proceeds of approximately $84 million and $98 million, respectively.

The Company sold 242 million shares of the common stock of AF during 2020.

The Company's additions to fixed assets and capitalized software, which amounted to $406 million in 2021 and $348 million in 2020, 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 $52 million in six private equity funds that invest primarily in financial services companies.

Commitments and Obligations

The following sets forth the Company's future contractual obligations by the types identified in the table below as of December 31, 2021:

	Payment due by Period
Contractual Obligations
(In millions)	Total	Within 1 Year	1-3 Years	4-5 Years	After 5 Years
Current portion of long-term debt	$ 17	$ 17	$ -	$ -	$ -
Long-term debt	11,002	-	2,236	1,762	7,004
Interest on long-term debt	5,222	412	763	616	3,431
Net operating leases	2,499	389	657	529	924
Service agreements	325	209	84	26	6
Other long-term obligations	631	209	402	18	2
Total	$ 19,696	$ 1,236	$ 4,142	$ 2,951	$ 11,367

The above table does not include the liability for unrecognized tax benefits of $94 million as the Company is unable to reasonably predict the timing of settlement of these liabilities, other than approximately $34 million that may become payable during 2022.

The above does not include the remaining transitional tax payments related to the Tax Cuts and Jobs Act ("TCJA") of $62 million, which will be paid in installments beginning in 2023 through 2026.

Management's Discussion of Critical Accounting Policies and Estimates

Management makes estimates and judgments that affect reported amounts of assets, liabilities, revenue and expenses, and disclosure of contingent assets and liabilities. Management considers the policies discussed below to be critical to understanding the Company's financial statements because their application places the most significant demands on management's judgment, and requires management to make estimates about the effect of matters that are inherently uncertain. Actual results may differ from those estimates.

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.

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.

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.

See Note 2, Revenue, in the notes 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"). The Company records a liability when a loss is both probable and reasonably estimable which requires significant management judgment. 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 arise from such claims, 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% 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 disclosed in Note 8, Retirement Benefits, in the notes to the consolidated financial statements.

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: 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 60% equities and equity alternatives and 40% fixed income. At the end of 2021, the actual allocation for the U.S. plans was 65% equities and equity alternatives and 35% fixed income. The target asset allocation for the U.K. plans, which comprise approximately 81% of non-U.S. plan assets, is 26% equities and equity alternatives and 74% fixed income. At the end of 2021, the actual allocation for the U.K. plans was 28% equities and equity alternatives and 72% 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 following table shows the weighted average assumed rate of return and the discount rate at the December 31, 2021 measurement date used to measure pension expense in 2022 for the total Company, the U.S. and the Rest of World ("ROW").

	Total Company	U.S.	ROW
Assumed rate of return on plan assets	4.56 %	6.88 %	3.64 %
Discount rate	2.28 %	3.00 %	1.89 %

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 86% of total pension plan liabilities, as follows:

	0.5 Percentage Point Increase		0.5 Percentage Point Decrease
(In millions)	U.S.	U.K.	U.S.	U.K.
Assumed rate of return on plan assets	$ (24)	$ (54)	$ 24	$ 54
Discount Rate	$ 3	$ 3	$(4)	$(4)

The impact of discount rate changes 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, Retirement Benefits, in the notes 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 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. 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 2021, 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 2021 and concluded that a quantitative goodwill impairment test was not required in 2021 and that goodwill was not impaired.

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, Summary of Significant Accounting Policies, in the notes to the consolidated financial statements contains a summary of the Company's significant accounting policies, including a discussion of recently issued accounting pronouncements and their impact or potential future impact on the Company's financial results, if determinable, under the sub-heading "New Accounting Pronouncements."

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Market Risk and Credit Risk

Certain of the Company's revenues, expenses, assets and liabilities are exposed to the impact of interest rate changes and fluctuations in foreign currency exchange rates and equity markets.

Interest Rate Risk and Credit Risk

Interest income generated from the Company's cash, cash equivalents, and cash and cash equivalents held in a fiduciary capacity will vary with the general level of interest rates.

The Company had the following investments subject to variable interest rates:

(In millions)	December 31, 2021
Cash and cash equivalents	$ 1,752
Cash and cash equivalents held in a fiduciary capacity	$ 9,622

Based on the above balances, if short-term interest rates increased or decreased by 10%, or 1 basis point, over the course of the year, annual interest income, including interest earned on cash and cash equivalents held in a fiduciary capacity, would increase or decrease by approximately $1 million.

In addition to interest rate risk, our cash investments and fiduciary cash 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, cash equivalents, and cash and cash equivalents held in a fiduciary capacity, and will further restrict the portfolio as appropriate to market conditions. The majority of cash, cash equivalents and cash and cash equivalents held in a fiduciary capacity 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 tend 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 2021, the Company estimates net operating income would increase or decrease by approximately $57 million. The Company has exposure to approximately 80 foreign currencies overall. In Continental Europe, the largest amount of revenue from renewals for the Risk and 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 $75 million that are valued using readily determinable fair values and approximately $36 million of investments without readily determinable fair values. The Company also has investments of approximately $207 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 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, 2021, the Company owns approximately 14% of the common stock of Alexander Forbes ("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 (loss) in the consolidated statement of income. The fair value of this investment at December 31, 2021 was approximately $57 million.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Nature of Operations:

Marsh & McLennan Companies, Inc. (the "Company"), a global professional services firm, is organized based on the different services that it offers. Under this structure, the Company's two business segments are Risk and Insurance Services and Consulting.

The Risk and Insurance Services segment ("RIS") provides risk management solutions (risk advice, risk transfer and risk control and mitigation) as well as insurance and reinsurance broking and services for businesses, public entities, insurance companies, associations, professional services organizations, and private clients. The Company conducts business in this segment through Marsh and Guy Carpenter. Marsh provides data-driven risk advisory services and solutions to commercial and consumer clients. Guy Carpenter develops advanced risk, reinsurance and capital strategies that help clients grow profitably and identify and capitalize on emerging opportunities.

The Company conducts business in its Consulting segment through Mercer and Oliver Wyman Group. Mercer delivers advice and solutions that help organizations create a dynamic world of work, shape 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.

Business Update Related To COVID-19

The World Health Organization declared COVID-19 a pandemic in March 2020. For almost two years, the pandemic has impacted businesses globally including virtually every geography in which the Company operates. Our businesses have been resilient throughout the pandemic and demand for our advice and services remains strong as the global economic conditions continue to improve.

Although the majority of our colleagues continue to work remotely, the Company has provided guidelines on return to the office depending on the level of virus containment and local health and safety regulations in each geography. The safety and well-being of our colleagues is paramount and the Company expects to continue to service clients effectively in both the remote and in-office environments.

The Company had strong revenue growth in 2021 and benefited from the continued recovery of the global economy. However, uncertainty remains in the economic outlook and the ultimate extent of the impact of COVID-19 to the Company will depend on future developments that it is unable to predict, including new "waves" of infection from emerging variants of the virus, potential renewed restrictions and mandates by various governments or agencies, and the distribution and uptake of vaccines and vaccine boosters.

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. 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. 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. The Company is expected to complete the integration of JLT during 2022.

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.

Revenue:

The Company provides detailed discussion regarding its revenue policies in Note 2, Revenue.

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. The Company maintained $303 million and $270 million related to these regulatory requirements at December 31, 2021 and 2020, respectively.

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 are depreciated over periods ranging from 3 to 10 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 30 to 40 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)	2021	2020
Furniture and equipment	$ 811	$ 1,326
Land and buildings	385	379
Leasehold and building improvements	1,240	1,310
	2,436	3,015
Less-accumulated depreciation and amortization	(1,589)	(2,159)
	$ 847	$ 856

Investments:

The caption "Investment income (loss)" 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 in accordance with 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 2021, the Company recorded investment income of $61 million compared to an investment loss of $22 million in 2020 and investment income of $22 million in 2019. Investment income in 2021 is primarily due to gains from investments in private equity funds. The net investment loss in 2020 is primarily due to the loss on the sale of shares of Alexander Forbes ("AF"). 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.

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. 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, Goodwill and Other Intangibles, the Company elected to perform a qualitative impairment assessment during 2021.

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, 2021 and 2020.

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. The net periodic cost of the Company's defined benefit plans is measured on an actuarial basis using various methods and assumptions.

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 Company reviews its actuarial assumptions on an annual basis and modifies these assumptions based on current rates and trends.

The funded status of the Company's pension plans is recorded in the consolidated balance sheets and provides for a delayed recognition of actuarial gains or losses arising from changes in the projected benefit obligation due to changes in the assumed discount rates, differences between the actual and expected value of plan assets and other assumption changes. The unrecognized pension plan actuarial gains or losses and prior service costs not yet recognized in net periodic pension cost are recognized in Accumulated Other Comprehensive Income ("AOCI"), net of tax. These gains and losses are amortized prospectively out of AOCI over a period that approximates the remaining life expectancy of participants in plans where substantially all participants are inactive, or the average remaining service period of active participants for plans with active participants. The vast majority of unrecognized losses relate to inactive plans and are amortized over the remaining life expectancy of the participants.

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.

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 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").

See Note 8, Retirement Benefits for additional information.

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. Right-of-use ("ROU") assets and lease liabilities are recorded at the lease commencement date. Lease liabilities are recognized at the present value of the contractual fixed lease payments. 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. ROU assets are recognized equal to lease liabilities, adjusted for prepaid lease payments, initial direct costs and lease incentives. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are expensed as incurred.

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

See Note 12, Leases for additional information.

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 $475 million and $481 million, net of accumulated amortization of $1.7 billion and $1.6 billion as of December 31, 2021 and 2020, 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 Company records a liability when a loss is both probable and reasonably estimable which requires significant management judgment. 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 arise from such claims, 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, 2021, the Company's liability for errors and omissions was $434 million, compared to $639 million at December 31, 2020, of which $79 million and $271 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 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% 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 ROU 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.

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 $15 million, $46 million and $105 million in 2021, 2020 and 2019, respectively. Since cash and cash equivalents held in a fiduciary capacity 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 $13.0 billion and $11.2 billion at December 31, 2021 and 2020, 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.

The Company, through its Mercer subsidiary, 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:

•	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;
•	the allowance for current expected credit losses on receivables;
•	useful lives assigned to long-lived assets, and depreciation and amortization; and
•	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. The Company also considered potential COVID-19 impacts to its customer base in various industries and geographies. Insurance exposures subject to variable factors are subject to midterm and end of term adjustments, as well as policy audits, which may reduce premiums and corresponding commissions. Estimates were updated based on internal and industry specific economic data. The ultimate extent to which COVID-19 will directly or indirectly impact the Company's businesses, results of operations and financial condition will depend on numerous evolving factors and future developments that it is not able to predict. Actual results may differ from these estimates.

New Accounting Pronouncement Adopted Effective January 1, 2022:

In October, 2021, the FASB issued new guidance for measuring contract assets and contract liabilities acquired in a business combination. In accordance with the new guidance, contract assets and contract liabilities should be measured in accordance with the guidance for revenue from contracts with customers as opposed to the guidance for business combinations. The guidance must be applied on a prospective basis, and is effective for fiscal years beginning after December 15, 2022, including interim periods therein. Early adoption is permitted. The Company elected to adopt this new standard effective January 1, 2022. Adoption of this guidance will not have a material impact on the Company's financial position or results of operations.

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: (i) exception to the incremental approach for intraperiod tax allocation; (ii) exceptions to accounting for basis differences when there are ownership changes in foreign investments and (iii) 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 (i) franchise taxes that are partially based on income; (ii) transactions with a government that result in a step-up in the tax basis of goodwill; (iii) separate financial statements of legal entities that are not subject to tax and (iv) 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 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.

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 approximately 2% 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 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. 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 and are received over the 12 to 18 months following the effective date of the placement.

In addition to compensation from its clients, the Company 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 underwriting services and 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 Marsh & McLennan Agency ("MMA") and 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, and 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. Therefore, revenue is typically 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 following table disaggregates various components of the Company's revenue:

(In millions)	For the Years Ended December 31,

The following table provides contract assets and contract liabilities information from contracts with customers.

(In millions)	December 31, 2021	December 31,2020	December 31, 2019
Contract assets	$ 290	$ 236	$ 207
Contract liabilities	$ 776	$ 676	$ 593

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 1,2021 to December 31, 2021 is primarily due to $547 million of additions during the period, partly offset by $493 million transferred to accounts receivables, as the rights to bill and collect became unconditional. The change in contract assets from January 1, 2020 to December 31, 2020 is primarily due to $311 million of additions during the period offset by $284 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, 2021 to December 31, 2021 includes cash received for performance obligations not yet fulfilled of $642 million offset by revenue recognized in 2021 of $539 million that was included in the contract liability balance at the beginning of the year. The Company recognized revenue of $527 million in 2020 that was included in the contract liability balance at January 1, 2020.

The amount of revenue recognized in 2021, 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 $84 million, $97 million, and $79 million respectively.

The Company applies the practical expedient and 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 $187 million, primarily related to Mercer. The Company expects revenue in 2022, 2023, 2024, 2025 and 2026 and beyond of $70 million, $63 million, $31 million, $14 million and $9 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, 2021, the Company's capitalized assets related to deferred implementation costs, costs to obtain and costs to fulfill were $24 million, $290 million and $316 million, respectively. 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. 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 compensation and benefits expense of $1.5 billion, $1.3 billion and $1.2 billion for the years ended December 31, 2021,2020 and 2019, respectively, related to the amortization of these capitalized assets.

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 Company recorded share-based compensation expense related to restricted stock units, performance stock units and stock options of $348 million, $290 million and $252 million for the years ended December 31, 2021, 2020 and 2019, respectively.

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.

An analysis of the allowance for credit losses for the years ended December 31, 2021 and 2020 is provided below. The analysis for 2019 is based on the Company's allowance for doubtful accounts model prior to adoption of the new accounting guidance:

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 eight acquisitions during 2021.

•	April - Marsh McLennan Agency ("MMA") acquired PayneWest Insurance, Inc., a Montana-based full-service broker providing business insurance, surety, employee benefits and personal insurance services to companies and individuals, and The Pryor Group, LLC, a Texas-based fullservice broker providing business insurance with a specialty in quick service restaurants and the personal lines of franchise owners.
•	September - MMA acquired Vaaler Insurance, Inc., a North Dakota-based insurance broker providing business insurance, employee health and benefits, and personal lines solutions, with specialized expertise in the construction, education, and healthcare industries.
•	November - MMA acquired Pelnik Insurance, a North Carolina-based full-service broker providing business insurance, employee health and benefits, and private client services to midsize businesses and individuals throughout the Mid-Atlantic, Southwest Truck Insurance Agency, Inc., a Texas-based broker providing business insurance for the trucking industry, serving clients in the U.S., and Mexico and InSource Insurance Group LLC, a Texas-based full-service broker providing business insurance, employee health and benefits, private client and surety services to the oil and gas, construction, manufacturing, and transportation industries.
•	December - Marsh acquired Services Assurance Monétique (SAM), a France-based affinity insurance broker specializing in bank and retail insurance markets and increased its ownership interest in Marsh India Insurance Broker Private Limited ("Marsh India") from 49% to 92%.

The Consulting segment completed one acquisition during 2021.

•	November - Oliver Wyman Group acquired Huron Consulting Group's life sciences strategy consulting practice in the U.S. and the U.K., which assists clients in addressing their most important commercial strategy, marketing, pricing, market access and research and development challenges.

Total purchase consideration for acquisitions made during 2021 was approximately $1.4 billion, which consisted of cash paid of $888 million, deferred purchase and estimated contingent consideration of $153 million and the fair value of a previously held equity method investment in Marsh India of $390 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 2021, the Company also paid $89 million of deferred purchase consideration and $77 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 2021 based on the estimated fair values for the acquisitions as of their respective acquisition dates.

Acquisitions for the Year-Ended December 31, 2021

(In millions)

Cash	$ 888
Estimated fair value of deferred/contingent consideration	153
Fair value of previously-held equity method investment	390
Total consideration	$ 1,431
Allocation of purchase price:
Cash and cash equivalents	$ 11
Cash and cash equivalents held in a fiduciary capacity	18

Fiduciary liabilities	18
Long-term lease liabilities	36
Other liabilities	105
Total liabilities assumed	231
Non-controlling interests	64
Net assets acquired	$ 1,431

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 following table provides information about intangible assets acquired during 2021:

Intangible assets through December 31, 2021		Weighted Average
(In millions)	Amount	Amortization Period
Customer relationships	$ 494	13.3 years
Other	14	3.8 years
	$ 508

The consolidated statement of income for 2021 includes approximately $114 million of revenue and operating income of $3 million related to acquisitions made during 2021. The consolidated statement of income for 2020 includes approximately $169 million of revenue and $11 million of operating income related to acquisitions made during 2020, and 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.

In 2021 and 2020, acquisition-related costs were $5 million and $3 million, respectively, primarily related to legal fees. In 2019, the Company incurred acquisition-related costs, primarily for legal, investment banking and U.K. stamp duty tax related to the acquisition of JLT, of $125 million.

In December 2021, in connection with its increased investment in Marsh India, the Company recorded a gain of $267 million related to the re-measurement of its previously held equity method investment to fair value. The fair value of the pre-existing equity method investment was calculated using an average of applying an income approach based on discounted future cash flows and market approach.

Dispositions

During 2021, the Company sold certain businesses, primarily in the U.S. and the U.K., for cash proceeds of approximately $84 million and recognized a net gain of approximately $50 million, primarily related to the commercial networks business in the U.K. that provided broking and back-office solutions for small independent brokers.

Prior year acquisitions

During 2020, the Risk and Insurance Services segment completed seven acquisitions.

•	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.

•	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 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 2020, the Company also paid $68 million of deferred purchase consideration and $102 million of contingent consideration related to acquisitions made in prior years.

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

Prior year dispositions

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

In February and May 2020, the Company sold approximately 240 million shares of the common stock of Alexander Forbes (AF). 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.

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 2021, 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 2021 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.

Changes in the carrying amount of goodwill are as follows:

(In millions)	2021	2020
Balance as of January 1, as reported	$ 15,517	$ 14,671
Goodwill acquired	1,045	593
Other adjustments ^(a)	(245)	253
Balance at December 31,	$ 16,317	$ 15,517

^(a) Primarily reflects the impact of foreign exchange and dispositions.

The goodwill acquired in 2021 and 2020 included approximately $96 million and $179 million, 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, $12.5 billion and Consulting, $3.8 billion.

December 31,
(In millions)	2021	2020
Balance sheet classifications:
Deferred tax assets	$ 551	$ 702
Other liabilities	$ 737	$ 561

The amount of cumulative undistributed earnings that are indefinitely reinvested in non-U.S. subsidiaries is approximately $730 million as of December 31, 2021. 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 $70 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:

For the Years Ended December 31,	2021	2020	2019
U.S. Federal statutory rate	21.0 %	21.0 %	21.0%
U.S. state and local income taxes-net of U.S. Federal income tax benefit	2.3	2.5	3.0
Differences related to non-U.S. operations	0.1	2.3	3.0
U.K. statutory rate change	2.6	-	-
Gain on consolidation of business	(1.5)	-	-
Equity compensation	(0.7)	(1.4)	(1.3)
Uncertain tax positions	0.1	1.1	-
Other	0.7	1.2	1.6
Effective tax rate	24.6 %	26.7 %	27.3 %

The rates in all periods reflect the effects of tax planning and the ongoing impact of regulatory and other guidance as it became available. The tax rate in 2021 includes the effect of a statutory rate change in the U.K., the tax effect of a gain from the fair value re-measurement of the Company's previously held equity method investment in Marsh India upon the Company increasing its ownership interest from 49% to 92%, which the Company has asserted will be indefinitely reinvested, and certain tax planning. 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.

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 $36 million, $72 million and $60 million in 2021, 2020, and 2019, respectively. Adjustments of the beginning of the year balances of valuation allowances increased income tax expense by $2 million during 2021. Adjustments of the beginning of the year valuation allowances in 2020 decreased income tax expense by $14 million, while in 2019 changes to the beginning of year valuation allowance had no impact on income tax expense. Approximately 29% of the Company's net operating loss carryforwards expire from 2022 through 2038, and others are unlimited. The potential tax benefit from net operating loss carryforwards at the end of 2021 comprised federal, state and local, and non-U.S. tax benefits of $9 million, $24 million, and $246 million, respectively, before reduction for valuation allowances.

Following is a reconciliation of the Company's total gross unrecognized tax benefits for the years ended December 31, 2021, 2020 and 2019:

(In millions)	2021	2020	2019
Balance at January 1,	$ 98	$ 86	$ 78
Additions, based on tax positions related to current year	2	9	8
Additions for tax positions of prior years	11	25	15
Reductions for tax positions of prior years	(1)	(9)	(1)
Settlements	(1)	(4)	(1)
Lapses in statutes of limitation	(15)	(9)	(13)
Balance at December 31,	$ 94	$ 98	$ 86

Of the total unrecognized tax benefits at December 31,2021,2020 and 2019, $87 million, $90 million and $75 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, 2021,2020 and 2019, before any applicable federal benefit, was $45 million, $40 million and $31 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. During 2021, the IRS concluded its examination of the Company's 2017, 2018 and 2019 tax returns. Due to its status as a compliant taxpayer, the Company was accepted into the Bridge phase of the CAP program for tax years 2020 and 2021, and therefore, generally will not be audited by the IRS for those years.

New York is a significant tax jurisdiction for the Company. New York State and New York City have continuing examinations underway for various entities covering the years 2010 through 2018. During 2020, New York City initiated an audit for the tax years 2016 through 2018.

We conduct business through multiple legal entities in significant jurisdictions outside the United States. Separate audits for individual entities within a jurisdiction may open or close within a particular year.

The status of audits for significant jurisdictions outside the United States are summarized in the table below:

Tax Audit (Years)

Jurisdiction:	Initiated in 2021	Ongoing	Concluded
France		2017-2018	2011, 2012 during 2018
Germany		2013-2016	2009-2012 during 2018
Hong Kong	2019
Italy		2015-2017
Singapore	2017-2019	2018
United Kingdom	2019	2016-2018	2014, 2015 during 2018

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 $47 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.

Combined U.S. and Non-U.S. Plans

The weighted average actuarial assumptions utilized for the U.S. and significant non-U.S. defined benefit plans and post-retirement benefit plans are as follows:

	Pension Benefits		Post-retirement Benefits
	2021	2020	2021	2020
Weighted average assumptions:
Discount rate (for expense)	1.92 %	2.57 %	2.42 %	2.72 %
Expected return on plan assets	4.73 %	5.31 %	-	-
Rate of compensation increase (for expense) ^*	1.85 %	1.76 %	-	-
Discount rate (for benefit obligation)	2.28 %	1.92 %	2.36 %	2.42 %
Rate of compensation increase (for benefit obligation) ^*	2.16 %	1.85 %	-	-

^* Rate of compensation increase assumptions include a zero percent 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 target asset allocation for the U.S. plans is 60% equities and equity alternatives and 40% fixed income. At the end of 2021, the actual allocation for the U.S. plans was 65% equities and equity alternatives and 35% fixed income. The target asset allocation for the U.K. plans, which comprise approximately 81% of non-U.S. plan assets, is 26% equities and equity alternatives and 74% fixed income. At the end of 2021, the actual allocation for the U.K. plans was 28% equities and equity alternatives and 72% 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 components of the net periodic benefit cost for defined benefit and other post-retirement plans are as follows:

Pension Settlement Charge

The Company recorded $5 million, $3 million and $7 million of non-cash settlement charges for the years ended December 31, 2021, 2020 and 2019 respectively, related to 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.

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 56-64% for equities and equity alternatives, and 36-44% for fixed income. For the U.K. plans, the category ranges are 23-29% for equities and equity alternatives, and 71-77% 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.

The weighted average actuarial assumptions utilized in determining expense during the year and benefit obligation at the end of the year for the U.S. defined benefit and other U.S. post-retirement plans are as follows:

	U.S. Pension Benefits		U.S. Post-retirement Benefits
	2021	2020	2021	2020
Weighted average assumptions:
Discount rate (for expense)	2.73 %	3.44 %	2.18 %	3.10 %
Expected return on plan assets	7.03 %	7.82 %	-	-
Discount rate (for benefit obligation)	3.00 %	2.73 %	2.56 %	2.18 %

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 $6.6 billion and $5.5 billion, respectively, as of December 31,2021 and $6.9 billion and $5.1 billion, respectively, as of December 31, 2020.

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 $6.6 billion and $5.5 billion, respectively, as of December 31, 2021 and $6.9 billion and $5.1 billion, respectively, as of December 31, 2020. The decrease in the benefit obligation in 2021 compared to 2020 reflects the increase in discount rates used to measure plan liabilities.

As of December 31, 2021, 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 6.3% of that plan's assets as of December 31, 2021.

The components of the net periodic benefit credit (cost) for the U.S. defined benefit and other postretirement benefit plans are as follows:

U.S. Plans only	Pension

The assumed health care cost trend rate for Medicare eligibles and non-Medicare eligibles is approximately 5.5% in 2021, gradually declining to 4% in 2045. 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 $31 million to its U.S. plans in 2022. 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 weighted average actuarial assumptions utilized in determining expense during the year and benefit obligation at the end of the year for the non-U.S. defined benefit plans are as follows:

	Non-U.S. Pension Benefits		Non-U.S. Post-retirement Benefits
	2021	2020	2021	2020
Weighted average assumptions:
Discount rate (for expense)	1.49 %	2.09 %	1.96 %	2.53 %

Rate of compensation increase (for benefit obligation)	3.34 %	2.84 %	-	-

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 $1.6 billion and $1.2 billion, respectively, as of December 31, 2021 and $3.1 billion and $2.5 billion, respectively, as of December 31, 2020.

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 $1.7 billion and $1.2 billion, respectively, as of December 31, 2021 and $3.3 billion and $2.6 billion, respectively, as of December 31, 2020.

The decrease in the benefit obligation in 2021 compared to 2020 reflects an actuarial gain primarily due to the increase in discount rates used to measure plan liabilities.

Components of Net Periodic Benefits Costs

The components of the net periodic benefit cost for the non-U.S. defined benefit and other post-retirement benefit plans and the curtailment, settlement and termination expenses are as follows:

For the Years Ended December 31,	Non-U.S. Pension Benefits

The assumed health care cost trend rate was approximately 4.94% in 2021, gradually declining to 4.36% 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 $147 million to its non-U.S. pension plans in 2022. 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.

During 2021, the JLT Pension Scheme was merged into the MMC U.K. Pension Fund with a new segregated JLT section created. The Company made deficit contributions of $38 million to the JLT section in 2021 and is expected to make contributions totaling approximately $112 million in 2022. The funding level of the JLT section will be reassessed during 2022 to determine contributions from 2023 onwards.

For the MMC U.K. Pension Fund, excluding the JLT section, an agreement was reached with the trustee in the 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, as part of the December 31, 2021 actuarial valuation, 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 £450 million over a seven-year period.

Estimated Future Benefit Payments

The estimated future benefit payments for the Company's pension and post-retirement benefit plans are as follows:

For the Years Ended December 31,	Pension Benefits		Post-retirement Benefits

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, Fair Value Measurements, 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, 2021 and 2020:

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: Trust assets include mutual funds that are valued based on readily determinable market values and other assets 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.

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.

Short-term investment funds: Primarily high-grade money market instruments valued at a readily determinable price.

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 $742 million of the 401 (k) Plans' assets at December 31, 2021 and $537 million at December 31, 2020 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 $150 million in 2021, $145 million in 2020 and $139 million in 2019. 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 $141 million, $121 million and $100 million in 2021, 2020 and 2019, 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, the 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 approved 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 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 2021, 2020 and 2019 are as follows:

	2021	2020	2019
Risk-free interest rate	0.79 %	1.44 %	2.51 %
Expected life (in years)	6.0	6.0	6.0
Expected volatility	23.45 %	20.33 %	20.93 %
Expected dividend yield	1.58 %	1.53 %	1.82 %

A summary of the status of the Company's stock option awards as of December 31, 2021 and changes during the year then ended is presented below:

	Shares	Weighted Average Exercise Price	Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value
				($000)
Balance at January 1, 2021	7,769,895	$ 79.71
Granted	1,324,618	$ 117.53
Exercised	(1,676,783)	$ 61.42
Forfeited	(200,605)	$ 105.98
Balance at December 31, 2021	7,217,125	$ 90.17	6.4 years	$ 601,999
Options vested or expected to vest at December 31, 2021	7,128,248	$ 89.98	6.5 years	$ 595,954
Options exercisable at December 31, 2021	3,988,943	$ 75.19	5.1 years	$ 392,470

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, 2021, 2020 and 2019 was $22.25, $21.09 and $17.87, respectively. The total intrinsic value of options exercised during the same periods was $137.5 million, $159.3 million and $136.7 million, respectively.

As of December 31, 2021, there was $15.0 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 1.13 years. Cash received from the exercise of stock options for the years ended December 31, 2021, 2020 and 2019 was $103.0 million, $72.0 million and $106.5 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 distributed.

The payout for PSU awards granted prior to 2020 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 and 2021 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 and 2021 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 2021 include:

	2021
Risk-Free Interest Rate	0,20 %
Dividend Yield	1.7 %
Volatility	25.0 %
Initial TSR	2.6 %

A summary of the status of the Company's RSU and PSU awards as of December 31, 2021 and changes during the period then ended is presented below:

	Restricted Stock Units		Performance Stock Units
	Shares	Weighted Average Grant Date Fair Value	Shares	Weighted Average Grant Date Fair Value
Non-vested balance at January 1,2021	5,513,681	$ 101.22	656,682	$ 101.54
Granted	2,469,062	$ 120.19	250,813	$ 122.77
Vested	(2,125,113)	$ 97.26	(197,216)	$ 83.05
Forfeited	(309,168)	$ 106.91	(48,089)	$ 111.76
Non-vested balance at December 31, 2021	5,548,462	$ 110.86	662,190	$ 114.35

The weighted-average grant-date fair value of the Company's RSU awards granted during the years ended December 31, 2020 and 2019 was $118.20 and $92.50, respectively. The weighted average grant date fair value of the Company's PSU awards granted during the years ended December 31, 2020 and 2019 was $127.71 and $91.17, respectively. The total fair value of the shares distributed during the years ended December 31, 2021, 2020 and 2019 in connection with the Company's non-option equity awards was $277.8 million, $290 million and $211.9 million, respectively.

The payout of shares in 2021 with respect to the PSU awards granted in 2018 was 110% of target based on performance for the three-year performance period. In aggregate, 217,003 shares became distributable in respect to PSUs vested in 2021.

As of December 31, 2021, there was $384 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 one 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 362,230 shares during the year ended December 31, 2021 and at December 31, 2021, 4,516,058 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 121,873 shares during the year ended December 31, 2021 and there were 1,034,131 shares available for issuance at December 31, 2021 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)	quoted prices for similar assets or liabilities in active markets;
b)	quoted prices for identical or similar assets or liabilities in non-active markets (examples include corporate and municipal bonds, which trade infrequently);
c)	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
d)	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 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 Funds and Mutual Funds - Level 1

Investments for which market quotations are readily available are valued at the sale price on their principal exchange or, for certain markets, official closing bid price. Money market funds are valued at a readily determinable price.

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, 2021 and 2020:

^(d) Included in accounts payable and accrued liabilities and other liabilities in the consolidated balance sheets.
^(e) U.S. Treasury bills with maturity dates of three months or less.

The Level 3 assets in the table reflect contingent purchase consideration from the sale of businesses. The change in the contingent purchase consideration assets from December 31, 2020 is driven primarily by cash receipts of approximately $90 million, partially offset by accretion and adjustments to the fair value of the contingent purchase consideration assets.

During the year ended December 31, 2021, 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 related to contingent consideration from acquisitions for the years ended December 31, 2021 and December 31, 2020.

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 $207 million and $280 million at December 31,2021 and 2020, respectively.

Investments in Public and Private Companies

The Company has investments in private insurance and consulting companies with a carrying value of $58 million and $169 million at December 31, 2021 and 2020, 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. In December 2021, the Company increased its ownership in Marsh India from 49% to 92%. Prior to the increase in ownership, the Company accounted for the investment under the equity method of accounting.

Private Equity Investments

The Company's investments in private equity funds were $149 million and $111 million at December 31, 2021 and 2020, 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 $56 million and $3 million from these investments for the years ended December 31, 2021 and 2020, respectively.

Other Investments

At December 31, 2021 and 2020 the Company held certain equity investments with readily determinable market values of $75 million and $72 million, respectively. In 2021 and 2020, the Company recorded investment losses on these investments of $5 million and losses of $27 million, respectively. The Company also held investments without readily determinable market values of $36 million and $33 million at December 31, 2021 and 2020, respectively.

The Company sold 242 million shares of the common stock of AF during 2020. The investment in AF, which was accounted for using the equity method of accounting prior to the sale of these shares, is accounted for at fair value, with unrealized investment gains and losses recorded as investment income (loss) in the consolidated statement of income.

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, 2021. During 2021, the U.S. dollar value of the euro notes decreased $100 million through December 31, 2021 due to the impact of foreign exchange rates, with a corresponding decrease to accumulated other comprehensive loss.

JLT Derivatives and Hedging Activity

JLT Fair Value Debt Derivative Contracts

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 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 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.

JLT Acquisition Related Derivatives

Foreign Exchange Forward Contract

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.

Foreign Exchange Contract on Euro Debt Issuance

In March 2019, the Company issued €1.1 billion of senior notes related to the JLT Transaction. 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.

Treasury Locks on Senior Notes

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. Upon issuance of the $5 billion of senior notes, the Company settled the treasury lock derivatives and made a payment to its counterparty 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.

12. Leases

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. 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.

Operating leases are recognized on the balance sheet as ROU assets and operating lease liabilities based on the present value of the remaining future minimum payments over the lease term at commencement date of the lease.

The Company determined that $16 million and $28 million of its ROU assets were impaired, and therefore, recorded a charge to the consolidated statement of income for the year ended December 31, 2021 and 2020, respectively, with an offsetting reduction to ROU assets.

The following table provides additional information about the Company's property leases:

On April 9, 2021, the Company increased its short-term commercial paper financing program to $2.0 billion from $1.5 billion. The Company had no commercial paper outstanding at December 31, 2021.

Credit Facilities

On April 2, 2021, the Company entered into an amended and restated multi-currency unsecured $2.8 billion five-year revolving credit facility ("New Facility"). The interest rate on the New Facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. The New Facility expires in April 2026 and requires the Company to maintain certain coverage and leverage ratios which are tested quarterly. The New Facility includes provisions for determining a LIBOR successor rate in the event LIBOR reference rates are no longer available or in certain other circumstances which are determined to make using an alternative rate desirable. As of December 31, 2021, the Company had no borrowings under this facility.

In connection with the New Facility, the Company terminated its previous multi-currency unsecured $1.8 billion five-year revolving credit facility and its unsecured $1 billion 364-day unsecured revolving credit facility.

In January 2020, the Company closed on a $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, which were subsequently repaid during the third and fourth quarters of 2020. These two facilities were terminated as of December 31, 2020 after repayment of the initial draw down.

Additional credit facilities, guarantees and letters of credit are maintained with various banks aggregating $508 million at December 31,2021 and $573 million at December 31, 2020. There were no outstanding borrowings under these facilities at December 31, 2021 and December 31, 2020.

Senior Notes

In December 2021, the Company issued $400 million of 2.375% senior notes due 2031 and $350 million of 2.90% senior notes due 2051. The Company used the net proceeds from these issuances for general corporate purposes and repaid $500 million of 2.75% senior notes with an original maturity date of January 2022 in December 2021.

On April 15, 2021, the Company repaid $500 million of senior notes maturing in July 2021.

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.

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 previous revolving credit facility.

In March 2020, the Company repaid $500 million of maturing senior notes.

Scheduled repayments of long-term debt in 2022 and in the four succeeding years are $17 million, $616 million, $1.6 billion, $518 million and $1.2 billion, 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.

	December 31, 2021		December 31, 2020
(In millions)	Carrying Amount	Fair Value	Carrying Amount	Fair Value
Short-term debt	$ 17	$ 17	$ 517	$ 523
Long-term debt	$ 10,933	$ 12,466	$ 10,796	$ 12,858

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.

14. Restructuring Costs

JLT Related Integration and Restructuring

The costs incurred in connection with the integration and restructuring of the combined businesses, primarily related to severance, real estate and technology rationalization, process management consulting fees, and legal fees for the rationalization of legal entity structures.

Since the acquisition of JLT, the Company has incurred JLT integration and restructuring costs of $679 million through December 31, 2021. This reflects $93 million and $251 million of costs incurred for the year ended December 31, 2021, and 2020, respectively.

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 is expected to complete the integration of JLT during 2022.

In connection with the JLT integration and restructuring, for the year ended December 31, 2021, the Company incurred costs of $93 million: $53 million in RIS, $36 million in Consulting, $4 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.

15. Common Stock

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. During 2021, the Company repurchased 7.9 million shares of its common stock for $1.2 billion. The Company remains authorized to purchase additional shares of its common stock up to a value of approximately $1.3 billion. There is no time limit on the authorization. The Company did not repurchase any of its common stock during 2020.

The Company issued approximately 3.8 million and 4.1 million shares related to stock compensation and employee stock purchase plans during the years ended December 31, 2021 and 2020, 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, Acquisitions and Dispositions, 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.

Nature of Contingencies

The Company and its subsidiaries are subject to a significant number of claims, lawsuits and proceedings in the course of our 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 buyout transactions and the provision of consulting services relating to the drafting and interpretation of trust deeds and other documentation governing pension plans. These claims often 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.

Our activities are regulated under the laws of the United States and its various states, United Kingdom, the European Union and its member states, and the many other jurisdictions in which the Company operates. The Company also receives subpoenas in the ordinary course of business, and from time, to time requests for information in connection with government investigations.

Current Matters

Risk and Insurance Services Segment

•	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. These individuals, including the former JLT employee, have since pleaded guilty to criminal charges. In December 2021, the U.S. Department of Justice (DOJ) notified JLT of its intention to decline to pursue any charges against any JLT entity and to seek disgorgement of $29 million in alleged gross profits on this account. JLT has agreed in principle to this resolution, and the Company recorded a charge for this amount in the fourth quarter 2021. We are cooperating with all ongoing investigations related to this matter.
•	From 2014, Marsh Ltd. was engaged by Greensill Capital (UK) Limited as its insurance broker. Marsh Ltd. placed a number of trade credit insurance policies for Greensill. On March 1,2021, Greensill filed an action against certain of its trade credit insurers in Australia seeking a mandatory injunction compelling these insurers to renew coverage under expiring policies. Later that day, the Australian court denied Greensill's application. Since then, a number of Greensill entities have filed for, or been subject to, insolvency proceedings, and several litigations and investigations have been commenced in the U.K., Australia, Germany, Switzerland and the U.S.

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 reflected projected redress amounts based on the limited number of files examined as part of the Skilled Person's review and report. Thereafter, the FCA expanded the scope of the 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. Payments of redress and expenses during 2021, together with a reduction of the actuarial estimates of future redress payments, reduced the recorded liability to £16 million (or $22 million) as of December 31, 2021. We expect to finalize the suitability review and redress calculations and to make substantially all redress payments by the end of the first quarter of 2022. This gross liability has been, and we anticipate will continue to be, partially offset by a contractual indemnity obligation and insurance recoveries from third-party E&O insurers.

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

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 are partly reinsured by a related party of River Thames. Payment of claims under the reinsurance agreement is collateralized by funds withheld by River Thames from the reinsurer. 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

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.

18. Revision of Prior Period Financial Statements

During the fourth quarter of 2021, the Company revised the presentation of cash and cash equivalents held in a fiduciary capacity in the consolidated statements of cash flows.

Historically, the Company did not present cash and cash equivalents held in a fiduciary capacity in the statements of cash flows, since these funds cannot be used for general purposes and were not considered a source of liquidity for the Company. The Company has since revised its presentation and includes cash and cash equivalents held in a fiduciary capacity as a component of total cash, cash equivalents, and cash and cash equivalents held in a fiduciary capacity, in the consolidated statements of cash flows.

Based on an analysis of quantitative and qualitative factors in accordance with SEC Staff Accounting Bulletins ("SAB") No. 99 Materiality and SAB No. 108, Considering the Effects of Prior Years Misstatements When Quantifying Misstatements in Current Year Financial Statements, the Company concluded the effect of the change was not material to any previously filed interim or annual financial statements. Accordingly, the Company revised the previously reported financial information in this Annual Report on Form 10-K in the consolidated statements of cash flows and related disclosures for the years ended December 31, 2020 and 2019, and for the unaudited interim periods ended March 31, 2021, June 30, 2021 and September 30, 2021.

The tables below reflect the impact to the consolidated statements of cash flows for the years ended December 31,2020 and 2019, and to the previously filed unaudited quarterly reports on Form 10-Q for the three months ended March 31, 2021, six months ended June 30, 2021 and the nine months ended September 30, 2021:

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, 2021 and 2020, the related consolidated statements of income, comprehensive income, cash flows, and equity for each of the three years in the period ended December 31, 2021, 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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, 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, 2021, 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 16, 2022, 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.

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.

Item 9A. Controls and Procedures.

Disclosure Controls and Procedures. Based on their evaluation, as of the end of the period covered by this annual report on Form 10-K, the Company's chief executive officer and chief financial officer have concluded that the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934) are effective.

In addition, we considered the revision of our Consolidated Statements of Cash Flows for the years ended December 31, 2020 and December 31, 2019 to comply with the guidance in accordance with ASC 230, "Statement of Cash Flows" as disclosed in Note 18, Revision of Prior Period Financial Statements, in the notes to the consolidated financial statements of this Form 10-K, and concluded that such revision does not represent a material weakness in our internal control over financial reporting.

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, 2021 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, 2021.

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, 2021.

(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, 2021, 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, 2021, 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, 2021, of the Company and our report dated February 16, 2022, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
