Products sold include property & casualty homeowners and/or commercial insurance as well as life, accident and health insurance coverages. Private Client Services provides sales and service to high net worth individuals, families and their advisors and focuses on delivery of property and casualty risk management solutions.

Effective January 1, 2013, the Corporate Benefits and Association businesses transferred to Mercer, while the Private Client Services and Sponsored Program & Franchise businesses will remain within the Insurance Services Businesses division at Marsh.

In 2011, Marsh decided to exit its business processing outsourcing ("BPO") business and in 2012, Marsh decided to exit its individual life insurance business in the U.S. known as Private Client Life Insurance Services, both of which were previously included in the Marsh U.S. Consumer operating unit.

Schinnerer Group. As one of the largest underwriting managers of professional liability and specialty insurance programs in the United States, Victor O.

Compensation for Services in Risk and Insurance Services

Marsh and Guy Carpenter are compensated for brokerage and consulting services primarily through fees and commissions. Commission rates vary in amount depending upon the type of insurance or reinsurance coverage provided, the particular insurer or reinsurer selected, the capacity in which the broker acts and negotiations with clients. Marsh and Guy Carpenter receive interest income on certain funds (such as premiums and claims proceeds) held in a fiduciary capacity for others. In certain countries, Marsh is compensated for insurer consulting services in the form of a fee or as a percentage of premium (or a combination of both). For a more detailed discussion of revenue sources and factors affecting revenue in our Risk and Insurance Services segment, see Part II, Item7 (“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 United States federal and state laws, as well as laws of other countries in which the Company's subsidiaries operate. See Part I, Item1A (“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, managing

7

general agents and third party administrators) to hold an individual and/or company license from a governmental 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 intermediary brokers is generally less rigorous as compared to insurance regulation, and most jurisdictions require only corporate reinsurance intermediary licenses.

Beginning in January 2005, all European Union member states were required to implement the Insurance Mediation Directive. This Directive aims to apply consistent minimum professional standards to insurance and reinsurance intermediaries, including a licensing system based on an assessment of factors such as professional competence, financial capacity and professional indemnity insurance. The adoption by member states of the European Union of regulations to comply with the Directive has led our insurance intermediary operations in the European Union to become subject to enhanced regulatory requirements. In January 2005, as part of the implementation of the Directive in the United Kingdom, the power and responsibilities of the Financial Services Authority ("FSA") were expanded to include regulation of insurance and reinsurance intermediaries in the United Kingdom.

Insurance authorities in the United States and certain other jurisdictions in which the Company's subsidiaries do business, including the FSA 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 Corp., a broker-dealer and investment adviser, registered in the U.S. with the SEC, and a member of the Financial Industry Regulatory Agency (FINRA) and the Securities Investor Protection Corporation (SIPC), primarily in connection with investment banking-related services relating to insurance-linked and alternative risk financing transactions. Also in the United States, Marsh uses the services of NIA Securities, LLC, a U.S. registered broker-dealer and investment adviser. Guy Carpenter provides advice on securities or investments in the European Union through MMC Securities (Europe) Limited, which is authorized and regulated by the FSA. Marsh also receives investment management services in the European Union from Marsh Investment Services Limited, which is also regulated by the FSA. MMC Securities Corp., MMC Securities (Europe) Limited, NIA Securities, LLC, and Marsh Investment Services Limited are indirect, wholly-owned subsidiaries of Marsh& McLennan Companies, Inc.

In some jurisdictions, insurance-related taxes may be due either directly from clients or from the insurance broker. In the latter case, the broker customarily looks to the client for payment.

Consulting.Certain of Mercer's retirement-related consulting services are subject to pension law and financial regulation in many countries, including by the SEC in the United States and the FSA in the United Kingdom. In addition, the trustee services, investment services (including advice to persons, institutions and other entities on the investment of pension assets and assumption of discretionary investment management responsibilities) and retirement and employee benefit program administrative services provided by Mercer and its subsidiaries and affiliates are subject to investment and securities regulations in various jurisdictions. The benefits insurance consulting and brokerage services provided by Mercer and its subsidiaries and affiliates are subject to the same licensing requirements and regulatory oversight as the insurance market intermediaries described above regarding our Risk and Insurance Services businesses. Mercer uses the services of MMC Securities Corp. with the provision of certain retirement and employee benefit services. Oliver Wyman Group uses the services of MMC Securities Corp. (in the United States) and MMC Securities (Europe) Limited (in the European Union), primarily in connection with corporate finance advisory services.

COMPETITIVE CONDITIONS

8

The Company faces strong competition in all of its businesses from providers of similar products and services, including competition with regard to identifying and pursuing acquisition candidates. The Company also encounters strong competition throughout its businesses from both public corporations and private firms in attracting and retaining qualified employees. In addition to the discussion below, see “Risks Relating to the Company Generally-Competitive Risks,” in Part I, Item1A of this report.

Risk and Insurance Services.The Company's combined insurance and reinsurance services businesses are global in scope. The principal bases upon which our insurance and reinsurance

businesses compete include the range, quality and cost of the services and products provided to clients. The Company encounters strong competition from other insurance and reinsurance brokerage firms that operate on a nationwide or worldwide basis, from a large number of regional and local firms in the United States, the European Union and elsewhere, from insurance and reinsurance companies that market, distribute and service their insurance and reinsurance products without the assistance of brokers or agents and from other businesses, including commercial and investment banks, accounting firms and consultants, that provide risk-related services and products.

Certain insureds and groups of insureds have established programs of self insurance (including captive insurance companies) as a supplement or alternative to third-party insurance, thereby reducing in some cases their need for insurance placements. Certain insureds also obtain coverage directly from insurance providers. There are also many other providers of affinity group and private client services, including specialized firms, insurance companies and other institutions.

Consulting.The Company's consulting and HR outsourcing businesses face strong competition from other privately and publicly held worldwide and national companies, as well as regional and local firms. These businesses compete generally on the basis of the range, quality and cost of the services and products provided to clients. Competitors include independent consulting and outsourcing firms, as well as consulting and outsourcing operations affiliated with accounting, information systems, technology and financial services firms.

Mercer's investments business faces competition from many sources, including multi-manager services offered by other investment consulting firms and financial institutions. In many cases, clients have the option of handling the services provided by Mercer and Oliver Wyman Group internally, without assistance from outside advisors.

Item 1A.      Risk Factors

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

RISKS RELATING TO THE COMPANY GENERALLY

Legal and Regulatory Issues

We are subject to significant uninsured exposures arising from “errors and omissions” claims.

Our operating companies provide numerous professional services, including the placement of insurance and the provision of consulting, actuarial and other services for corporate and public clients around the world. As a result of these activities, the Company and its subsidiaries are subject to a significant number of errors and omissions, or “E&O” claims, particularly in our Marsh and Mercer businesses in the U.S. and the U.K. In our Risk and Insurance Services segment, such claims include allegations of damages arising from our failure to adequately place coverage or notify insurers of potential claims on behalf of clients. In our Consulting segment, such claims include allegations of damages arising from our actuarial, consulting, pension administration and other services, which frequently involve (1) assumptions and estimates concerning contingent future events, (2) complex drafting and interpretation of documentation governing pension plans, and (3) calculating benefits within complicated pension structures. Given the long-tail nature of professional liability claims, E&O matters often relate to services provided by the Company dating back many years. In each of our segments, E&O claims seek damages, including punitive and treble damages, in amounts that could, if awarded, be significant and subject us to potential liability for monetary damages, negative publicity, reputational harm and to diversion of personnel and management resources.

In establishing liabilities for errors and omissions claims in accordance with FASB ASC Subtopic No.450-20 (Contingencies-Loss Contingencies), the Company utilizes case level reviews by inside and outside counsel, an internal actuarial analysis and other analysis 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. Nevertheless, given the unpredictability of E&O claims and of litigation that could flow from them, it is possible that an adverse outcome in a particular

12

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.

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.

Further, as more fully described in Note 15 to our consolidated financial statements included under Part II, Item8 of this report, we are subject to legal proceedings, regulatory investigations and other contingencies other than E&O claims which, if determined unfavorably to us, could have a material adverse effect on our business, results of operations or financial condition.

Our internal systems and controls cannot guarantee that we are in compliance with all 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 may 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 European Union and its member states, and the other jurisdictions in which we operate. For example, we are subject to regulation by foreign and domestic governments, regulatory agencies such as the SEC in the United States and the FSA in the United Kingdom, and self-regulatory organizations

such as FINRA, as described further above under Part I, Item1 - Business (Regulation) of this report. The foreign and U.S. laws and regulations that are applicable to our operations are complex and may increase the costs of regulatory compliance, limit or restrict the products or services we sell or subject our business to the possibility of regulatory actions or proceedings. These laws and regulations include trade sanctions laws such as the Iran Threat Reduction and Syria Human Rights Act of 2012, anti-corruption laws such as the U.S. Foreign Corrupt Practices Act and the UK Bribery Act 2010, local laws prohibiting corrupt payments to governmental officials, as well as import and export restrictions.

As a publicly-traded company, we are subject to additional federal, state and other rules and regulations, including those required by the Sarbanes-Oxley Act of 2002 and the Dodd-Frank Wall Street Reform and Consumer Protection Act. Compliance with the requirements of these laws and regulations may be costly and adversely affect our business.

While we attempt to comply with all applicable laws and regulations, there can be no assurance that we, our employees, our consultants or our contractors are in full compliance with all applicable laws and regulations or interpretations of these laws and regulations at all times or that we will be able to comply with any future laws or regulations. If we fail to comply with applicable laws and regulations, including those referred to above, we may be subject to investigations, criminal sanctions or civil remedies, 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. The cost of compliance or the consequences of non-compliance could have a material adverse effect on our businesses, results of operations or financial condition. In addition, these matters could have a material adverse effect on the Company by exposing us to negative publicity, reputational damage or harm to our client or employee relationships.

In most jurisdictions, government regulatory authorities have the power to interpret or amend applicable laws and regulations, and have discretion to grant, renew and revoke various licenses and approvals we need to conduct our activities. Such authorities may require the Company to incur substantial increases in 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 those of regulatory authorities, we might 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.

The method by which insurance intermediaries are compensated has received substantial scrutiny in the past decade because of the potential for conflicts of interest. The amount of compensation that we receive from insurance companies, including in the form of consulting and other services, has increased

13

in the last two years. Future changes in the regulatory environment may impact our ability to earn certain revenue streams. Adverse regulatory developments regarding the forms of compensation that we earn could have a material adverse effect on our business, results of operations or financial condition.

Finally, government involvement in the insurance or reinsurance markets could displace insurance or reinsurance currently available from the private market and adversely affect our business, results of operations or financial condition.

Improper disclosure of personal data could result in legal liability or harm our reputation.

In many jurisdictions, we are subject to laws relating to the collection, use, retention, security and transfer of our clients' confidential and proprietary information and the personal information of our employees, our individual customers, and our clients' employees and retirement and other benefit plan participants. In many cases, these laws apply not only to third-party transactions, but also to transfers of information among our affiliates. We maintain policies, procedures and technological safeguards designed to protect the security and privacy of this information. Nonetheless, we cannot entirely eliminate the risk of improper access to or disclosure of personal information. Such disclosure could harm our reputation and subject us to liability under our contracts, as well as laws and regulations, resulting in increased costs or loss of revenue.

Further, data privacy is subject to frequently changing laws, rules and regulations in the various jurisdictions and countries in which we operate. For example, a revision to the 1995 European Union Data Protection Directive is currently being considered by European legislative bodies that may include more stringent operation requirements and significant penalties for non-compliance. Our failure to adhere to or successfully implement processes in response to changing legal or regulatory requirements in this area could result in legal liability or impairment to our reputation in the marketplace, as well as the general risks described above relating to our compliance systems and controls.

Financial Risks

Our pension obligations may cause the Company's earnings and cash flows to fluctuate.

The Company has significant pension obligations to its current and former employees, totaling approximately $13.8 billion and related plan assets of approximately $12.2 billion at December 31, 2012. 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. In the U.S., contributions to the tax-qualified defined benefit plans are based on ERISA guidelines. Contribution rates for non-US plans are generally based on local funding practices and statutory requirements, which may differ from measurements under U.S. GAAP. In the U.K., for example, contributions to defined benefit pension plans are determined through a negotiation process between the Company and the plans' trustee that typically occurs every three years in conjunction with the actuarial valuation of the plans. This process is governed by U.K. pension regulations. The assumptions that result from the funding negotiations are different from those used for U.S. GAAP and currently result in a lower funded status than under U.S. GAAP.

During 2012, the Company contributed $124 million to its U.S. pension plans and $389 million to non-U.S. pension plans. As more fully described in Note 8 to our consolidated financial statements, funding amounts will be impacted by future asset performance, the assumed interest rates we use to discount our pension liabilities, rates of inflation, mortality assumptions and other variables impacting the assets and/or liabilities of the plan. In accordance with ASC Topic No. 715, the Company reflects the over- or under-funded amount of its pension plans as assets or liabilities, respectively. Given the magnitude of our worldwide pension plans, variations in any of the preceding factors could cause significant fluctuation in our earnings as well as our equity from year to year and may result in increased levels of contributions to our pension plans, particularly in the U.K.

Our results of operations could be adversely affected by economic and political conditions and the effects of these conditions on our clients' businesses and levels of business activity.

Global economic and political conditions affect our clients' businesses and the markets they serve. These economic conditions may reduce demand for our services or depress pricing of those services, which

14

could have a material adverse effect on our results of operations. Changes in global economic conditions could also shift demand to services for which we do not have competitive advantages, and this could negatively affect the amount of business that we are able to obtain. Should it become necessary for us to restructure our business, including reducing our work force, as a result of market conditions or other factors that reduce the demand for our products and services, our ability to execute our business strategy could be adversely affected.

Financial institution failures may cause us to incur increased expenses or make it more difficult either to utilize our existing debt capacity or otherwise obtain financing for our operations, investing activities (including the financing of any future acquisitions), or financing activities.

Our cash investments, including those held in a fiduciary capacity, are subject to general credit, liquidity, counterparty, market and interest rate risks that may be exacerbated by the difficulties faced by financial institution counterparties. If the banking system or the fixed income, credit or equity markets deteriorate, the values and liquidity of our investments could be adversely affected.

Concerns regarding the European debt crisis and market perceptions concerning the instability of the Euro could adversely affect the Company's operating results as well as the value of the Company's Euro-denominated assets.

Concerns persist regarding the ability of certain Eurozone countries to service their debt obligations. As a result, a number of these countries have undertaken a variety of actions, such as cutting spending and raising taxes, designed to ease their future debt burdens. A potential consequence may be stagnant growth, or even recession, in the Eurozone economies and beyond. Also, the stability of the Euro and its viability as a single currency is being called into question. In the future, certain countries may find it advantageous to leave the Eurozone and reintroduce their local currencies to retain better control over their economic situations. A more extreme outcome is the complete dissolution of the Euro. Any of these developments could lead to further contraction in the Eurozone economies, adversely affecting our operating results in the region. The Company may also face increasedcredit risk as our clients and financial institution counterparties in the region find themselves with reduced resources to meet their obligations. Finally, the value of the Company's assets held in the Eurozone, including cash holdings, will decline if the currency devalues.

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

We are subject to exchange rate risk because some of our subsidiaries receive revenue other than in their functional currencies, and because we must translate the financial results of our foreign subsidiaries into U.S. dollars. Our U.S. operations earn revenue and incur expenses primarily in U.S. dollars. In certain jurisdictions, however, our Risk and Insurance Services operations generate revenue in a number of different currencies, but expenses are almost entirely incurred in local currency. Due to fluctuations in foreign exchange rates, we are subject to economic exposure as well as currency translation exposure on the profits of our operations. Exchange rate risk could have a significant impact on our financial condition, results of operations or cash flow.

Increased counterparty risk and changes in interest rates could reduce the value of our investment portfolio and adversely affect our financial results.

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 low.

Credit rating downgrades would increase our financing costs and could subject us to operational risk.

Currently, the Company's senior debt is rated Baa2 by Moody's and BBB by S&P. These ratings are the next-to-lowest investment grade rating for each of Moody's and S&P. Ratings from both S&P and Moody's currently carry a Stable outlook.

15

If we need to raise capital in the future (for example, in order to fund maturing debt obligations or finance acquisitions or other initiatives), a credit rating downgrade would increase our financing costs, and could limit our access to financing sources. Further, we believe that a downgrade to a rating below investment-grade could result in greater operational risks through increased operating costs and increased competitive pressures.

We are a holding company and, therefore, may not be able to receive dividends or other distributions in needed amounts from our subsidiaries.

The Company is organized as a holding company, a legal entity separate and distinct from our operating subsidiaries. As a holding company without significant operations of our own, we are dependent upon dividends and other payments from our operating subsidiaries to meet our obligations for paying principal and interest on outstanding debt obligations, for paying dividends to stockholders and for corporate expenses. In the event our operating subsidiaries are unable to pay dividends and other payments to the Company, we may not be able to service debt, pay obligations or pay dividends on common stock.

Further, the Company derives a significant portion of its revenue and operating profit from operating subsidiaries located outside the U.S. Since the majority of financing obligations as well as dividends to stockholders are made from the U.S., it is important to be able to access cash generated outside the U.S.

Funds from the Company's operating subsidiaries outside the U.S. are regularly repatriated to the U.S. via stockholder distributions and intercompany financings. A number of factors may arise that could limit our ability to repatriate funds or make repatriation cost prohibitive, including, but not limited to, foreign exchange rates and tax-related costs.

In the event we are unable to generate cash from our operating subsidiaries for any of the reasons discussed above, our overall liquidity could deteriorate.

Our quarterly revenues and profitability may fluctuate significantly.

Quarterly variations in revenues and operating results may occur due to several factors. These include:

• the significance of client engagements commenced and completed during a quarter;

• the possibility that clients may decide to delay or terminate a current or anticipated project as a result of factors unrelated to our work product or progress;

• fluctuations in hiring and utilization rates and clients' ability to terminate engagements without penalty;

• seasonality due to the impact of regulatory deadlines, policy renewals and other timing factors to which our clients are subject;

• the success of our strategic acquisitions, alliances 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 certain business lines are derived from the value of assets under management (or administration), and declines in global securities markets; and

• general economic conditions, since results of operations are directly affected by the levels of business activity of our clients, which in turn are affected by the level of economic activity in the industries and markets that they serve.

A significant portion of our total operating expenses is relatively fixed in the short term. Therefore, a variation in the number of client assignments or in the timing of the initiation or the completion of client assignments can cause significant variations in quarterly operating results for these businesses.

International Operations

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

We do business worldwide. In 2012, 56% of the Company's total revenue was generated from operations outside the United States, and over one-half of our employees are located outside the United States. We expect to expand our non-U.S. operations further.

The geographic breadth of our activities subjects us to significant legal, economic, operational, market, compliance and reputational risks. These include, among others, risks relating to:

16

• economic and political conditions in foreign countries, including the European debt crisis;

• unexpected increases in taxes or changes in U.S. or foreign tax laws;

• withholding or other taxes that foreign governments may impose on the payment of dividends or other remittances to us from our non-U.S. subsidiaries;

• potential transfer pricing-related tax exposures that may result from the allocation of U.S.-based costs that benefit our non-U.S. businesses;

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

• international hostilities, terrorist activities, natural disasters and infrastructure disruptions;

• local investment or other financial restrictions that foreign governments may impose;

• potential 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 such as the Iran Threat Reduction and Syria Human Rights Act of 2012, anti-corruption laws such as the U.S. Foreign Corrupt Practices Act and the UK Bribery Act 2010, local laws prohibiting corrupt payments to governmental officials, as well as import and export restrictions;

• limitations or restrictions that foreign or U.S. legislative bodies or regulators may impose on the products or services we sell or the methods by which we sell our products and services;

• 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;

• the length of payment cycles and potential difficulties in collecting accounts receivable, particularly in light of the increasing number of insolvencies in the current economic environment and the numerous bankruptcy laws to which they are subject;

• engaging and relying on third parties to perform services on behalf of the Company; and

• potential difficulties in monitoring employees in geographically dispersed locations.

Our inability to successfully recover should we experience a disaster or other business continuity problem could cause material financial loss, loss of human capital, regulatory actions, reputational harm or legal liability.

Should we experience a local or regional disaster or other business continuity problem, such as an earthquake, hurricane, terrorist attack, pandemic, security breach, cyber attack, power loss, telecommunications failure or other natural or man-made disaster, our continued success will depend, in part, on the 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, our operational size, the multiple locations from which we operate, and our existing back-up systems would provide us with an important advantage. Nevertheless, we could still experience near-term operational challenges with regard to particular areas of our operations, such as key executive officers or personnel.

Our operations are dependent upon our ability to protect our technology infrastructure against damage from business continuity events that could have a significant disruptive effect on our operations. We could potentially lose client data or experience material adverse interruptions to our operations or delivery of services to our clients in a disaster recovery scenario.

We regularly assess and take steps to improve upon our existing business continuity plans and key management succession. However, a disaster on a significant scale or affecting certain of our key operating areas within or across regions, or our inability to successfully recover should we experience a disaster or other business continuity problem, could materially interrupt our business operations and cause material financial loss, loss of human capital, regulatory actions, reputational harm, damaged client relationships or legal liability.

Competitive Risks

17

Each of the Company's businesses operates in a highly competitive environment. If we fail to compete effectively, our business and results of operations will suffer.

As a global professional services firm, the Company faces acute and continuous competition in each of its operating segments. Our ability to compete successfully depends on a variety of factors, including our geographic reach, the sophistication and quality of our services, our pricing relative to competitors and our customers' option to self-insure or utilize internal resources instead of consultants. If we are unable to respond successfully to the competition we face, our business and results of operations will suffer.

In addition, given the global breadth of the Company's operations, the Company derives a significant portion of its revenue and operating profit from operating subsidiaries located outside the United States. Funds from the Company's operating subsidiaries located outside the U.S. are regularly repatriated to the United States out of annual earnings to pay dividends to stockholders, fund share repurchases and for other corporate purposes. The Company's consolidated tax rate is higher than a number of its key competitors that are domiciled outside the United States where corporate tax rates are lower than the U.S. statutory tax rate. The consolidated tax rate at which our earnings are taxed could have an adverse impact on our ability to compete with our peers.

In our Risk and Insurance Services segment, we compete intensely against a wide range of other insurance and reinsurance brokerage firms that operate on a global, regional, national or local scale for both client business and employee talent. We compete as well with insurance and reinsurance companies that market and service their insurance products without the assistance of brokers or other market intermediaries, and with various other companies that provide risk-related services. The above competition is intensified by an industry trend toward a “syndicated” or “distributed” approach to the purchase of insurance and reinsurance brokerage services, whereby a client engages multiple brokers to service different portions of the client's account.

In our Consulting segment, we compete for business and employee talent with numerous consulting firms and organizations affiliated with accounting, information systems, technology and financial services firms around the world.

The loss of key professionals could hurt our ability to retain existing client revenues and generate revenues from new business.

Across all of our businesses, our colleagues are critical to developing and retaining the client relationships on which our revenues depend. It is therefore very important for us to 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 in all of our businesses and the general mobility of professionals in our businesses.

Losing employees 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 would adversely affect our results of operations. In addition, if any of our key professionals 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.

Consolidation in the industries we serve could adversely affect our business.

Companies in the industries that we serve may seek to achieve economies of scale and other synergies by combining with or acquiring other companies. If two or more of our current clients merge

or consolidate and combine their operations, it may decrease the amount of work that we perform for these clients. If one of our current clients merges or consolidates with a company that relies on another provider for its services, we may lose work from that client or lose the opportunity to gain additional work. Any of these possible results of industry consolidation could adversely affect our business. Guy Carpenter is especially susceptible to this risk given the limited number of insurance company clients and reinsurers in the marketplace.

Our businesses face rapid technological changes and our failure to adequately anticipate or respond to these changes or to successfully implement strategic initiatives could adversely affect our business and results of operations.

18

To remain competitive in many of our business areas, we must identify the most current technologies and methodologies and integrate them into our service offerings. In addition, we have a number of strategic initiatives involving investments in technology systems and infrastructure to support our growth strategy. In addition to new platforms and systems, we are deploying new processes and many of our colleagues across the business are changing the way they perform certain roles to capture efficiencies. If we do not keep up with technological changes or execute well on our strategic initiatives, our business and results of operations could be adversely impacted.

Acquisitions and Dispositions

We face risks when we acquire and dispose of businesses.

We have a history of making acquisitions, including a total of 41 acquisitions in the period 2009-2012 for aggregate purchase consideration of $1.7 billion. We have also exited various businesses, including the sale of Putnam Investments Trust (“Putnam”) in August 2007 and the sale of Kroll in 2010. We expect that acquisitions will continue to be a key part of our business strategy. Our success in this regard will depend on our ability to identify and compete for appropriate acquisition candidates and to complete with favorable results the transactions we decide to pursue.

While we intend that our acquisitions will improve our competitiveness and profitability, we cannot be certain that our past or future acquisitions will be accretive to earnings or otherwise meet our operational or strategic expectations. Acquisitions involve special risks, including accounting, regulatory, compliance, information technology or human resources issues that could arise in connection with, or as a result of, the acquisition of the acquired company; the potential assumption of unanticipated liabilities and contingencies and difficulties in integrating acquired businesses; and acquired businesses may not achieve the levels of revenue, profit or productivity we anticipate or otherwise perform as we expect. In addition, if in the future, the performance of our reporting units or an acquired business varies from our projections or assumptions, or estimates about future profitability of our reporting units or an acquired business change, the estimated fair value of our reporting units or an acquired business could change materially and could result in an impairment of goodwill and other acquisition-related intangible assets recorded on our balance sheet or in adjustments in contingent payment amounts. As of December31, 2012, the Company's consolidated balance sheet reflected $7.3 billion of goodwill and intangible assets, representing approximately 45% of the Company's total consolidated assets and allocated by reporting segment as follows: Risk and Insurance Services, $5.1 billion and Consulting, $2.2 billion. Given the significant size of the Company's goodwill and intangible assets, an impairment could have a material adverse effect on our results of operations in any given period.

When we dispose of businesses we are subject to the risk, contractually agreed or otherwise, of post-transaction liabilities. For example, as described in Note 15 to our consolidated financial statements included under Part II, Item8 of this report, we have retained certain contingent litigation liabilities relating to Kroll.

RISKS RELATING TO OUR RISK AND INSURANCE SERVICES SEGMENT

Our Risk and Insurance Services segment, conducted through Marsh and Guy Carpenter, represented 55% of the Company's total revenue in 2012. 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 and 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 may decide not to purchase our risk advisory 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 hampering our ability to place insurance and reinsurance business. Guy Carpenter is especially

19

susceptible to this risk given the limited number of insurance company clients and reinsurers in the market place.

Volatility or declines in premiums and other market trends may significantly impede our ability to improve 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. 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 general phenomenon of pricing cyclicality in the commercial insurance and reinsurance markets.

In addition to movements in premium rates, our ability to generate premium-based commission revenue may be challenged by 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 so-called “captive” insurers; and the advent of capital markets-based solutions to traditional insurance and reinsurance needs. Further, the profitability of our Risk and Insurances Services segment depends in part on our ability to be compensated not only for insurance and reinsurance transactions, but for the increasing analytical services and advice that we provide. If we are unable to achieve and maintain adequate billing rates for all of our services, our margins and profitability could suffer.

RISKS RELATING TO OUR CONSULTING SEGMENT

Our Consulting segment, conducted through Mercer and Oliver Wyman Group, represented 45% of our total revenue in 2012. Our businesses in this segment are subject to particular risks.

Demand for our services might decrease for various reasons, including a general economic downturn, a decline in a client's or an industry's financial condition, or changes in government regulation.

Our Consulting segment has historically achieved annual revenue growth. Despite this history, however, global economic conditions over the past several years have resulted in negative impacts on businesses and financial institutions. Many of our clients, including financial institutions, corporations, governmental entities and pension plans, have been reducing expenses, including amounts spent on consulting services. The evolving needs or financial circumstances of our clients may challenge our ability to increase revenues and profitability and reduce demand for our services. If the economy or markets in which we operate experience continued weakness at current levels or deteriorate further, our business, financial condition and results of operations could be materially and adversely affected.

In addition, demand for many of Mercer's benefits services is affected by government regulation and tax rules, which drive our clients' needs for benefits-related services. For example, 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 impacting defined benefit pension plans and the services we provide relating to those plans could adversely affect Mercer.

Mercer currently provides corporate, multi-employer and public clients with actuarial, consulting and administration services relating to defined benefit pension plans. The nature of our work is complex. Our actuarial services involve numerous assumptions and estimates regarding future events, including interest rates used to discount future liabilities, estimated rates of return for a plan's assets, healthcare cost trends, salary projections and participants' life expectancies. Our consulting services involve complex drafting and interpretation of trust deeds and other documentation governing pension plans. Our administration services include calculating benefits within complicated pension plan structures. Clients dissatisfied with our services have brought, and may bring, significant claims against us, particularly in the U.S. and the U.K. In addition, a number of Mercer's clients have frozen or curtailed their defined benefit plans and have moved to defined contribution plans resulting in reduced revenue for Mercer's retirement business. These developments could adversely affect Mercer's business and operating results.

20

Our profitability may suffer if we are unable to achieve or maintain adequate utilization and pricing rates for our consultants.

The profitability of our Consulting businesses depends in part on ensuring that our consultants maintain adequate utilization rates (i.e., the percentage of our consultants' working hours devoted to billable activities). Our utilization rates are affected by a number of factors, including:

• our ability to transition consultants promptly from completed projects to new assignments, and to engage newly-hired consultants quickly in revenue-generating activities;

• our ability to continually secure new business engagements, particularly because a portion of our work is project-based rather than recurring in nature;

• our ability to forecast demand for our services and thereby maintain appropriate headcount in each of our geographies and workforces;

• our ability to manage attrition;

• unanticipated changes in the scope of client engagements;

• the potential for conflicts of interest that might require us to decline client engagements that we otherwise would have accepted;

• our need to devote time and resources to sales, training, professional development and other non-billable activities;

• the potential disruptive impact of acquisitions and dispositions; and

• general economic conditions.

If the utilization rate for our consulting professionals declines, our profit margin and profitability may suffer.

In addition, the profitability of our Consulting businesses depends on the prices we are able to charge for our services. Our pricing power is 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;

• changes in 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 margins and profitability could suffer.

If we are unable to collect our receivables or unbilled services, our results of operations and cash flows could be adversely affected.

Our business depends on our ability to successfully obtain payment from our clients of the amounts they owe us for work performed. We typically bill and collect on relatively short cycles. There is no guarantee that we will accurately assess the creditworthiness of our clients. Macroeconomic conditions could also result in financial difficulties for our clients, and as a result 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. Timely collection of client balances depends on our ability to complete our contractual commitments and bill and collect our contracted revenues. If we are unable to meet our contractual requirements, we might experience delays in collection of and/or be unable to collect our client balances, and if this occurs, our results of operations and cash flows could be adversely affected. In addition, if we experience an increase in the time to bill and collect for our services, our cash flows could be adversely affected.

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

Item 2.      Properties.

Marsh & McLennan Companies and its subsidiaries maintain their corporate headquarters in and around New York City. We also maintain other offices around the world, primarily in leased space. In certain circumstances we may have space that we sublet to third parties, depending upon our needs in particular locations.

Marsh & McLennan Companies and certain of its subsidiaries own, directly and indirectly through special purpose subsidiaries, a 58% condominium interest of a building approximately 900,000 square feet and 44 stories in New York City. This real estate serves as the Company's headquarters and is occupied primarily by the Company and its affiliates for general corporate use. The remaining 42% condominium interest in the 1166 Property is owned by an unaffiliated third party. The Company’s owned interest is financed by a 30-year loan that is non-recourse to the Company (except in the event of certain prohibited actions) and secured by a first mortgage lien on the condominium interest and a first priority assignment of leases and rents. In the event (1) the Company is downgraded below B/B2 (Stable) by any of S&P, Fitch and Moody’s or (2) an event of default has occurred and is continuing, the Company would be obligated to pre-fund certain reserve accounts relating to the mortgaged property, including a rent reserve account in an amount equal to three months rent for the entire occupancy of the mortgaged property.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

General

Marsh & McLennan Companies, Inc. and Subsidiaries (the “Company”) is a global professional services firm providing advice and solutions principally in the areas of risk, strategy and human capital. It is the parent company of a number of the world’s leading risk experts and specialty consultants, including: Marsh, the insurance broker, intermediary and risk advisor; Guy Carpenter, the risk and reinsurance specialist; Mercer, the provider of HR and related financial advice and services; and Oliver Wyman Group, the management, economic and brand consultancy. With approximately 54,000 employees worldwide and annual revenue of nearly $12 billion, the Company provides analysis, advice and transactional capabilities to clients in more than 100 countries.

The Company conducts business through two segments:

• Risk and Insurance Services includes risk management activities (risk advice, risk transfer and risk control and mitigation solutions) as well as insurance and reinsurance broking and services. We conduct business in this segment through Marsh and Guy Carpenter.

• Consulting includes Retirement, Health, Talent and Investments consulting and services, and specialized management and economic consulting services. We conduct business in this segment through Mercer and Oliver Wyman Group.

The Company completed the sale of Kroll in August 2010, and along with other dispositions between 2008 and 2010, has divested its entire Risk Consulting and Technology Segment. The Company has “continuing involvement” in certain Corporate Advisory and Restructuring businesses (“CARG”) that were disposed of in 2008. The runoff of the CARG businesses is being managed by the Company's corporate departments and financial results of these entities are included in “Corporate” for segment reporting purposes.

We describe the primary sources of revenue and categories of expense for each segment below, in our discussion of segment financial results. A reconciliation of segment operating income to total operating income is included in Note 16 to the consolidated financial statements included in Part II Item 8 in this report. The accounting policies used for each segment are the same as those used for the consolidated financial statements.

This Management's Discussion & Analysis ("MD&A") contains forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. See “Information Concerning Forward-Looking Statements” at the outset of this report.

Consolidated operating income increased 12% to $1.8 billion in 2012 compared with $1.6 billion in 2011. Revenue in 2012 increased 3% compared to 2011, or 4% on an underlying basis, with growth in each operating company, while expenses increased 2%, or 3% on an underlying basis. This reflects the Company's improved operating efficiency as it continues to monitor and control its expenses in each of its operations.

Risk and Insurance Services operating income increased $145 million or 12% to $1.4 billion in 2012 compared with 2011, resulting from revenue growth at both Marsh and Guy Carpenter.

Consulting operating income increased $64 million or 11% to $652 million in 2012 compared with 2011 primarily due to increased revenue at Mercer and improved operating efficiency.

Consolidated operating income was $1.6 billion in 2011 compared with $939 million in 2010. The 2010 results include a $400 million charge, net of insurance recoveries, for the resolution of the litigation brought by the Alaska Retirement Management Board ("ARMB") and restructuring and other noteworthy items of $139 million. Excluding these charges, consolidated operating income was $1.5 billion in 2010.

Risk and Insurance Services operating income increased $257 million or 26% to $1.2 billion in 2011 compared with 2010, resulting from revenue growth at both Marsh and Guy Carpenter, continued expense discipline and a decrease of $132 million in restructuring and other noteworthy items.

Consulting operating income increased $459 million to $588 million in 2011 primarily due to the $400 million net charge related to the ARMB litigation settlement in 2010. Excluding that item, Consulting operating income increased $59 million, or 11%.

Discontinued operations in 2011 includes a net credit resulting from the resolution of certain legal matters and related insurance recoveries as well as the settlement of certain tax audits and the expiration of the statute of limitations related to certain indemnified matters in connection with the disposals of Putnam and Kroll. These credits are partly offset by the write-off, net of tax, of capitalized software related to the disposal of the Marsh Business Processing Outsourcing ("BPO") business. Discontinued operations in 2010 includes the operating results of Kroll, gains on the sales of Kroll and Kroll Laboratory Specialists

26

("KLS") totaling $282 million, and insurance recoveries of $16 million related to Putnam market-timing related matters.

Discontinued operations also includes the accretion of interest related to an indemnity for uncertain tax positions provided as part of the purchase by Great-West Life Co. Inc., of Putnam Investments Trust from the Company in August 2007.

Consolidated net income attributable to the Company was $1.2 billion in 2012, compared with $993 million in 2011 and $855 million in 2010.

Consolidated Revenue and Expense

The Company conducts business in many countries, as a result of which the impact of foreign exchange rate movements may impact period-to-period comparisons of revenue. Similarly, the revenue impact of acquisitions and dispositions 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 is as follows:

Revenue

Consolidated revenue for 2012 increased 3% to $11.9 billion compared with $11.5 billion in 2011, reflecting a 4% increase in underlying revenue, a 1% increase due to acquisitions and a 2% negative impact of foreign currency translation. Revenue in the Risk and Insurance Services segment increased 4% in 2012 compared with 2011 or 5% on an underlying basis, reflecting increases of 5% in Marsh and 6% in Guy Carpenter. Consulting segment revenue increased 2%, resulting from a 4% increase in Mercer partly offset by a 1% decrease in the Oliver Wyman Group. On an underlying basis, Consulting segment revenue increased 4%, reflecting a 4% increase in Mercer and a 3% increase in the Oliver Wyman Group.

Consolidated revenue for 2011 increased 9% to $11.5 billion compared with $10.6 billion in 2010, reflecting a 5% increase in underlying revenue, a 2% increase due to acquisitions and a 2% positive impact of foreign currency translation. Revenue in the Risk and Insurance Services segment increased 9% in 2011 compared with 2010 or 5% on an underlying basis, reflecting increases of 4% in Marsh and 5% in Guy Carpenter. Consulting segment revenue increased 9%, resulting from 9% increases in both Mercer and the Oliver Wyman Group. On an underlying basis, revenue increased 5%, reflecting a 4% increase in Mercer and a 7% increase in the Oliver Wyman Group.

Operating Expense

Consolidated operating expenses increased 2% in 2012 compared with the same period in 2011. The increase reflects a 3% increase in underlying expenses, a 1% increase due to the impact of acquisitions, offset by a 2% decrease due to the impact of foreign currency exchange translation. The increase in underlying expenses primarily reflects higher incentive compensation and benefits costs and restructuring costs at Mercer, which include exit costs related to a portion of Mercer's Canadian outsourcing business. These increases are partly offset by credits related to the adjustment of acquisition related contingent consideration liabilities.

Consolidated operating expenses increased 3% in 2011 compared with the same period in 2010. Expenses in 2010 include the $400 million ARMB settlement at Mercer. Restructuring and other noteworthy charges, which include legal fees arising from regulatory actions, net of insurance recoveries and credits related to the CARG business divested in 2008, decreased $116 million to $23 million in 2011 as compared to $139 million in 2010. Excluding these charges, expenses were $9.9 billion in 2011 compared with $9.1 billion in 2010, an increase of 9%. The increase reflects a 3% increase due to the impact of foreign currency exchange, a 2% increase due to the impact of acquisitions and a 4% increase in underlying expenses. The increase in underlying expenses primarily reflects higher compensation and benefits costs, including increased pension costs, higher consulting costs, asset-based fees and expenses reimbursable from clients.

Restructuring

In 2012, the Company implemented restructuring actions which resulted in costs totaling $78 million. Approximately $58 million of the restructuring charges related to Mercer, with approximately $51 million in expenses recorded in the fourth quarter of 2012 relating to senior management's operations review, including costs of approximately $16 million related to the disposal of a portion of Mercer's Canadian outsourcing business. The restructuring costs consist primarily of severance and benefits, costs for future rent and other real estate costs. These costs were incurred as follows: Risk and Insurance Services—$8 million (all acquisition related—$ 8 million); Consulting—$58 million (acquisition related—$1 million); and Corporate—$12 million.

Businesses Exited

Marsh's BPO business, previously part of the Marsh U.S. Consumer business, provided policy, claims, call center and accounting operations on an outsourced basis to life insurance carriers. Marsh invested in a technology platform that was designed to make the BPO business scalable and more efficient. During 2011, Marsh decided that it would cease investing in the technology platform and instead exit the business via a sale. In the fourth quarter of 2011, management initiated a plan to sell the Marsh BPO business, which was completed in August 2012. The Company wrote off capitalized software of the BPO business of $17 million, net of tax, which is included in discontinued operations in 2011.

30

In February 2010, Kroll sold KLS, its substance abuse testing business for $110 million. On August 3, 2010, the Company completed the sale of Kroll to Altegrity for $1.13 billion. The account balances and activities of Kroll and KLS have been segregated and reported as discontinued operations in the accompanying financial statements for 2010. The gain on the sale of Kroll and related tax benefits and the after- tax loss on the disposal of KLS, along with Kroll’s and KLS’s 2010 results of operations are included in discontinued operations.

Risk and Insurance Services

In the Risk and Insurance Services segment, the Company’s subsidiaries and other affiliated entities act as brokers, agents or consultants for insureds, insurance underwriters and other brokers in the areas of risk management, insurance broking and insurance program management services, primarily under the name of Marsh; and engage in reinsurance broking, catastrophe and financial modeling services and related advisory functions, primarily under the name of Guy Carpenter.

Marsh and Guy Carpenter are compensated for brokerage and consulting services primarily through fees paid by clients and/or commissions paid out of premiums charged by insurance and reinsurance companies. Commission rates vary in amount depending upon the type of insurance or reinsurance coverage provided, the particular insurer or reinsurer, the capacity in which the broker acts and negotiations with clients. Revenues can be affected by premium rate levels in the insurance/reinsurance markets, the amount of risk retained by insurance and reinsurance clients themselves and by the value of the risks that have been insured since commission based compensation is frequently related to the premiums paid by insureds/reinsureds. In many cases, fee compensation may be negotiated in advance, based on the type of risk, coverage required, and service provided by the Company and ultimately 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 certain countries, 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 provide for segregation of fiduciary funds and limit the types of investments that may be made with them. Interest income from these investments varies depending on the amount of funds invested and applicable interest rates, both of which vary from time to time. For presentation purposes, fiduciary interest is segregated from the other revenues of Marsh and Guy Carpenter and separately presented within the segment, as shown in the revenue by segments charts earlier in this MD&A. In certain countries, Marsh is compensated for insurer consulting services in the form of a fee or as a percentage of premium (or a combination of both).

Revenue

Revenue in Risk and Insurance Services increased 4% in 2012 compared with 2011 reflecting a 5% increase on an underlying basis, a 2% increase from acquisitions, partly offset by a 2% decrease from the impact of foreign currency exchange translation.

In Marsh, revenue in 2012 was $5.5 billion, an increase of 5% from the prior year, reflecting 5% growth in underlying revenue, a 2% increase from acquisitions partly offset by a 2% decrease resulting from the impact of foreign currency translation. The underlying revenue increase of 5% reflects growth in all major

31

geographies, driven by new business. Underlying revenue increased 13% in Latin America, 7% in Asia Pacific, 3% in U.S. / Canada and 5% in EMEA.

During 2012, Marsh completed the following twelve acquisitions:

• January - Marsh acquired Alexander Forbes' South African brokerage operations, including Alexander Forbes Risk Services and related ancillary operations and insurance broking operations in Botswana and Namibia to expand Marsh's presence in Africa. Marsh subsequently closed the acquisitions of the Alexander Forbes operations in Uganda, Malawi and Zambia.

• March - Marsh & McLennan Agency ("MMA") acquired KSPH, LLC, a middle-market employee benefits agency based in Virginia, and Marsh acquired Cosmos Services (America) Inc., the U.S. insurance brokerage subsidiary of ITOCHU Corp., which specializes in commercial property/casualty, personal lines, and employee benefits brokerage services to U.S. subsidiaries of Japanese companies.

• June - MMA acquired Progressive Benefits Solutions, an employee benefits agency based in North Carolina, and Security Insurance Services, Inc., a Wisconsin-based insurance agency which offers property/casualty and employee benefits products and services to individuals and businesses.

• August - MMA acquired Rosenfeld-Einstein, a South Carolina-based employee benefits service provider, and Eidson Insurance, a property/casualty and employee benefits services firm located in Florida.

• October - MMA acquired Howalt+McDowell, a South Dakota-based agency which offers property casualty, surety, personal protection and employee benefits insurance to individuals and businesses, and The Protector Group Insurance Agency, a Massachusetts-based agency which provides property casualty, employee benefits services, personal insurance and individual financial services.

• November - MMA acquired Brower Insurance, an Ohio-based company providing employee benefits, property casualty and consulting services.

• December - MMA acquired McGraw Wentworth, a Michigan-based company providing consulting services to mid-sized organizations, and Liscomb Hood Mason, a Minnesota-based company providing property casualty and employee benefits products and services.

The MMA acquisitions were made to expand Marsh's presence in the U.S. middle-market business.

In January 2011, Marsh acquired RJF Agencies, an independent insurance agency in the upper Midwest. In February 2011, Marsh acquired Hampton Roads Bonding, a surety bonding agency for commercial, road, utility, maritime and government contractors in the state of Virginia, and the Boston office of Kinloch Consulting Group, Inc. In July 2011, Marsh acquired Prescott Pailet Benefits, an employee benefits broker based in Texas. In October 2011, Marsh acquired the employee benefits division of Kaeding, Ernst & Co, a Massachusetts based employee benefits, life insurance and financial planning consulting firm. In November 2011, Marsh acquired Seitlin Insurance, a property and casualty insurance and employee benefits firm located in South Florida.

Guy Carpenter’s revenue increased 4% to $1.1 billion in 2012 compared with 2011, or 6% on an underlying basis driven by Carpenter's International operations, particularly Global Specialties, Asia Pacific, EMEA, Latin America, and Global Facultative.

Fiduciary interest income was $39 million in 2012 compared to $47 million in 2011 due to slightly lower average invested funds combined with lower interest rates.

Revenue in Risk and Insurance Services increased 9% in 2011 compared with 2010 reflecting a 5% increase on an underlying basis, a 3% increase from acquisitions, and a 2% increase from the impact of foreign currency exchange translation.

In Marsh, revenue in 2011 was $5.2 billion, an increase of 10% from the prior year, reflecting 4% growth in underlying revenue, a 4% increase from acquisitions and a 2% increase resulting from the impact of foreign currency translation. The underlying revenue increase of 4% reflected growth in all major

32

geographies, driven by higher retention rates and new business development. Underlying revenue increased 14% in Latin America, 9% in Asia Pacific, 3% in U.S. / Canada and 4% in EMEA.

Guy Carpenter’s revenue increased 7% to $1.0 billion in 2011 compared with 2010, or 5% on an underlying basis. The increase in underlying revenue was driven by strong new business development and high retention rates.

Fiduciary interest income was $47 million in 2011 compared to $45 million in 2010 due to higher average invested funds partly offset by lower interest rates.

Expense

Expenses in the Risk and Insurance Services segment increased 3% in 2012 compared with 2011, reflecting a 2% increase from acquisitions and a 2% decrease due to the impact of foreign currency translation. Expenses on an underlying basis increased 3% primarily due to higher base salaries and incentive compensation and benefits costs partly offset by credits related to adjustments to acquisition related contingent consideration liabilities.

Expenses in the Risk and Insurance Services segment increased 6% in 2011 compared with 2010, reflecting a 3% increase from acquisitions and a 2% increase due to the impact of foreign currency translation. Expenses on an underlying basis increased 1%. The increase in underlying expenses is primarily due to higher base salaries and incentive compensation costs, non-restructuring related severance costs and facilities and equipment costs, partly offset by lower restructuring expenses and a credit of $31 million for insurance recoveries on previously expensed legal fees.

Consulting

The Company conducts business in its Consulting segment through two main business groups. Mercer provides consulting expertise, advice, services and solutions in the areas of talent, health, retirement and investments. Oliver Wyman Group provides specialized management, economic and brand consulting services.

The major component of revenue in the Consulting segment business is fees paid by clients for advice and services. Mercer, principally through its health & benefits 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 outsourcing businesses consists principally of fees based on assets under management or administration.

Revenue in the Consulting segment is affected by, among other things, global economic conditions, including changes in clients’ particular industries and markets. Revenue is also affected by competition due to the introduction of new products and services, broad trends in employee demographics, including levels of employment, the effect of government policies and regulations, and fluctuations in interest and foreign exchange rates. Revenues from the provision of investment management services and retirement trust and administrative services are significantly affected by securities market performance.

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

(In millions of dollars)	2012			2011			2010
Revenue	$	5,382		$	5,265		$	4,835
Compensation and Benefits	3,221			3,233			2,974
Other Operating Expenses	1,509			1,444			1,732
Operating Expenses	4,730			4,677			4,706
Operating Income	$	652		$	588		$	129
Operating Income Margin	12.1		%	11.2		%	2.7		%

Revenue

Consulting revenue in 2012 increased 2% compared with 2011, or 4% on an underlying basis. Mercer’s revenue was $3.9 billion in 2012, an increase of 4% on both a reported and underlying basis as

33

compared to 2011, with growth in each of its businesses. The underlying revenue growth was primarily driven by a 7% increase in health and benefits and an 8% increase in investments. Oliver Wyman’s revenue decreased 1% in 2012 compared to 2011, but increased 3% on an underlying basis.

During 2012, Mercer completed the following three acquisitions:

• February - Mercer acquired the remaining 49% of Yokogawa-ORC, a global mobility firm based in Japan, which was previously accounted for under the equity method, and Pensjon & Finans, a leading Norway-based financial investment and pension consulting firm.

• March - Mercer acquired REPCA, a France-based broking and advisory firm for employer health and benefits plans.

Consulting revenue in 2011 increased 9% compared with 2010, or 5% on an underlying basis. Mercer’s revenue was $3.8 billion in 2011, an increase of 9% or 4% on an underlying basis. Within Mercer’s consulting lines, revenue on an underlying basis increased 4% in 2011 compared with 2010, reflecting increases of 6% in health and benefits and 11% in talent, rewards & communications, partly offset by a 1% decline in retirement. Outsourcing revenue grew 9% and was flat on an underlying basis. Investments revenue increased 26% or 11% on an underlying basis. Oliver Wyman’s revenue increased 9% to $1.5 billion in 2011, or 7% on an underlying basis.

Expense

Consulting expenses in 2012 increased 1%, or 3% on an underlying basis. This increase reflects the impact of higher benefits and restructuring costs, including charges of $16 million for the exit activities related to a portion of Mercer's Canadian outsourcing business.

Consulting expenses in 2011 decreased 1% to $4.7 billion, or 4% on an underlying basis. Mercer recorded a $400 million net charge related to the ARMB settlement in 2010. Excluding this charge, expenses increased 4% on an underlying basis. This increase reflected the impact of higher base-salaries and incentive compensation and benefits costs, including higher pension costs, and higher asset-based fees and recoverable expenses from clients.

Corporate and Other

The following results of Corporate and Other includes the run-off of CARG operations:

(In millions of dollars)	2012			2011			2010
Corporate Advisory and Restructuring Operating Income	$	6		$	9		$	10
Corporate Expense	(203		)	(188		)	(172		)
Total Corporate and Other	$	(197	)	$	(179	)	$	(162	)

Corporate expenses in 2012 were $203 million compared to $188 million in 2011. The increase is primarily due to accelerated amortization of equity awards for retirement eligible senior executives and higher consulting costs associated with corporate initiatives.

Corporate expenses in 2011 were $188 million compared to $172 million in 2010. The increase in Corporate expense reflects higher compensation and pension costs primarily due to executive positions added in corporate and higher outside services costs related to corporate initiatives, such as branding.

The CARG amounts reflect payments received related to the CARG businesses divested in 2008.

Discontinued Operations

As part of the disposal transactions for Putnam and Kroll, the Company provided certain indemnities, primarily related to pre-transaction tax uncertainties and legal contingencies. In accordance with applicable accounting guidance, liabilities were established related to these indemnities at the time of the sales and reflected as a reduction of the gain on disposal. Discontinued operations includes charges or credits resulting from the settlement or resolution of the indemnified matters, as well as adjustments to the

34

liabilities related to such matters. Discontinued operations in 2011 includes credits of$50 millionfrom the resolution of certain legal matters and insurance recoveries, as well as the settlement of tax audits and the expiration of the statutes of limitations related to certain of the indemnified matters, primarily with respect to Putnam.

Marsh's BPO business, previously part of Marsh U.S. Consumer business, provided policy, claims, call center and accounting operations on an outsourced basis to life insurance carriers. Marsh invested in a technology platform that was designed to make the BPO business scalable and more efficient. During 2011, Marsh decided that it would cease investing in the technology platform and instead exit the business via a sale. In the fourth quarter of 2011, management initiated a plan to sell the Marsh BPO business which was completed in August 2012. The Company wrote off capitalized software of the BPO business of $17 million, net of tax, which is included in discontinued operations in 2011.

In the first quarter of 2010, Kroll completed the sale of KLS and on August 3, 2010, the Company completed the sale of Kroll to Altegrity.

Kroll’s results of operations are reported as discontinued operations in the Company’s consolidated statement of income for the portion of 2010 prior to Kroll's disposal. The year ended 2010 also includes the gain on the sale of Kroll and related tax benefits and the loss on the sale of KLS, which includes the tax provision of $36 million on the sale.

The Company’s tax basis in its investment in the stock of Kroll at the time of sale exceeded the recorded amount primarily as a result of prior impairments of goodwill recognized for financial reporting, but not tax. A $265 million deferred tax benefit was recorded in discontinued operations in 2010 as a result of the sale of Kroll.

Summarized Statements of Income data for discontinued operations is as follows:

Other Corporate Items

Interest

Interest income earned on corporate funds amounted to $24 million in 2012 compared with $28 million in 2011. The decrease in interest income is due to lower average interest rates compared with the prior year. Interest expense was $181 million in 2012 compared with $199 million in 2011. The decrease is primarily due to lower interest rates on senior notes issued during the second half of 2011 and the first quarter of 2012, compared to the interest rate on notes that matured.

Interest income earned on corporate funds was $28 million in 2011 compared with $20 million in 2010. The increase in interest income was due to the combined effect of higher average invested funds in 2011 and slightly higher average interest rates compared with the prior year. Interest expense was $199 million in 2011 compared with $233 million in 2010. The decrease was primarily due to the maturity of senior notes in the third quarter of 2010, the early extinguishment of a portion of the Company's outstanding notes during the third quarter of 2011 and a lower net interest rate on the Company's debt subject to interest rate swaps. These decreases were partly offset by interest on new senior notes issued during the third quarter of 2011.

Early Extinguishment of Debt

On July 15, 2011 the Company purchased $600 million of the Outstanding Notes, comprised of $330 million of its 2014 Notes and $270 million of its 2015 Notes (collectively, the "Notes"). The Company acquired the Notes at market value plus a tender premium, which exceeded its carrying value and resulted in a charge of approximately $72 million in the third quarter of 2011.

Investment Income (Loss)

In 2012, investment income was $24 million compared with $9 million in 2011. This increase is primarily due to higher mark-to-market gains on private equity fund investments, partly offset by an impairment loss on a debt security of $8 million.

In 2011, investment income was $9 million compared with $43 million in 2010. This decrease primarily reflects the impact of lower private equity gains recorded in 2011 as compared to 2010, the effects of recording an impairment loss in 2011 and a gain on the sale of equity securities in 2010.

Income Taxes

The Company's consolidated effective tax rate was 29.0%, 30.1% and 26.5% in 2012, 2011 and 2010, respectively. The tax rate in each year reflects foreign operations which are taxed at rates lower than the U.S. statutory tax rate.

The lower effective tax rate attributed to the Company's foreign operations primarily reflects lower corporate tax rates that prevail outside of the U.S., net of the U.S. tax impact from repatriating foreign earnings. In 2012, pre-tax income in the U.K., Canada, Australia and Bermuda accounted for approximately 60% of the Company's total non-U.S. pre-tax income, with effective rates in those countries of 24% (excluding the non-cash deferred tax impact of UK tax legislation enacted in 2012), 27%, 30% and 0%, respectively. Under current U.S. tax law, the Company anticipates its non-U.S. operations will continue to incur taxes at rates below the U.S. federal tax rate of 35%.

The Company's non-U.S. revenue over the past three years has been approximately 55% of total revenue, while the pre-tax income from non-U.S. locations varied from 77% to 138% of total pre-tax income. Although revenue in the United States has been approximately 45% of total revenue, while the Company had gains in its U.S. operations in 2011 and 2012, the Company incurred pre-tax losses in the United States during 2010 as a result of a significant charge from the resolution of the ARMB matter, which is discussed in Note 1 to the Consolidated Financial Statements. The Company had pre-tax income in its U.S. operations in 2011 and 2012.

In addition, as a U.S. domiciled parent holding company, Marsh & McLennan Companies, Inc., is the issuer for essentially all of the Company's external indebtedness, and incurs the related interest expense in the U.S. Finally, most senior executive and oversight functions are conducted in the U.S. and the associated costs are incurred primarily in the United States.

36

The effective tax rate may vary significantly from period to period for the foreseeable future. It is sensitive to the geographic mix and repatriation of the Company's earnings, which may result in higher or lower tax rates. A proportional increase in U.S. pre-tax income will tend to increase the effective tax rate because U.S. federal and state corporate tax rates often exceed tax rates applicable outside the U.S. Losses in certain jurisdictions cannot be offset by earnings from other operations, and may require valuation allowances that affect the rate, depending on estimates of the realizability of associated deferred tax assets. The effective tax rate is also sensitive to changes in unrecognized tax benefits, including the impact of settled tax audits and expired statutes of limitation.

The realization of deferred tax assets depends on generating future taxable income during the periods in which the tax benefits are deductible or creditable. The Company and Marsh have been profitable globally. However, tax liabilities are determined and assessed on a legal entity and jurisdictional basis. Certain taxing jurisdictions allow or require combined or consolidated tax filings. In the United States, certain groups within the Company, which file on a combined basis, were profitable in 2011 and 2012, but incurred a loss in 2010 as a result of the resolution of the ARMB matter. The Company assessed the realizability of its domestic deferred tax assets, particularly state deferred tax assets of Marsh relating to jurisdictions in which it files separate tax returns, state deferred tax assets of all of the Company's domestic operations related to jurisdictions in which the Company files a unitary or combined state tax return, and foreign tax credit carry-forwards in the Company's consolidated U.S. federal tax return. When making its assessment about the realization of its domestic deferred tax assets at December 31, 2012, the Company considered all available evidence, placing particular weight on evidence that could be objectively verified. The evidence considered included (i) the profitability of the Company's U.S. operations in 2011 and 2012 and the cumulative period from 2010 through 2012, (ii) the nature, frequency, and severity of losses incurred before 2011, (iii) profit trends evidenced by continued improvements in the Company's and Marsh's operating performance, (iv) the non-recurring nature of some of the items that contributed to losses before 2011, (v) the carry-forward periods for the net operating losses ("NOLs") and foreign tax credit carry-forwards, (vi) the sources and timing of future taxable income, giving weight to sources according to the extent to which they can be objectively verified, and (vii) tax planning strategies that would be implemented, if necessary, to accelerate utilization of NOLs. Based on its assessment, the Company concluded that it is more likely than not that a substantial portion of these deferred tax assets are realizable and a valuation allowance was recorded to reduce the domestic deferred tax assets to the amount that the Company believes is more likely than not to be realized. In the event sufficient taxable income is not generated in future periods, additional valuation allowances of up to approximately $270 million could be required relating to these domestic deferred tax assets. The realization of the remaining U.S. federal deferred tax assets is not as sensitive to U.S. profits because it is supported by anticipated repatriation of future annual earnings from the Company's profitable global operations, consistent with the Company's historical practice. In addition, when making its assessment about the realization of its domestic deferred tax assets at December 31, 2012, the Company continued to assess the realizability of deferred tax assets of certain other entities with a history of recent losses, including other U.S. entities that file separate state tax returns and foreign subsidiaries, and recorded valuation allowances as appropriate.

Changes in tax laws or tax rulings may have a significant adverse impact on our effective tax rate. For example, proposals for fundamental U.S. international tax reform, if enacted, could have a significant adverse impact on the effective tax rate.

Liquidity and Capital Resources

The Company is organized as a holding company, a legal entity separate and distinct from its operating subsidiaries. As a holding company without significant operations of its own, the Company is dependent upon dividends and other payments from its operating subsidiaries to meet its obligations for paying principal and interest on outstanding debt obligations, for paying dividends to stockholders and for corporate expenses. Other sources of liquidity include borrowing facilities discussed below in financing cash flows.

The Company derives a significant portion of its revenue and operating profit from operating subsidiaries located outside of the United States. Funds from the Company’s operating subsidiaries located outside of the United States are regularly repatriated to the United States out of annual earnings. At December 31, 2012, the Company had approximately $1.3 billion of cash and cash equivalents in its foreign operations,

37

of which all but approximately $80 million is considered to be permanently invested in those operations to fund foreign investments and working capital needs. The non-U.S. cash and cash equivalents considered permanently reinvested includes approximately $250 million of operating funds required to be maintained for regulatory requirements or as collateral under certain captive insurance arrangements. The Company expects to continue its practice of repatriating foreign funds out of current annual earnings. While management does not foresee a need to repatriate the funds which are currently deemed permanently invested, if facts or circumstances change management could elect to repatriate them, if necessary, which could result in higher effective tax rates in the future.

Cash on our consolidated balance sheets includes funds available for general corporate purposes. Funds held on behalf of clients in a fiduciary capacity are segregated and shown separately in the consolidated balance sheets as an offset to fiduciary liabilities. Fiduciary funds cannot be used for general corporate purposes, and should not be considered as a source of liquidity for the Company.

Operating Cash Flows

The Company generated $1.3 billion of cash from operations in 2012 compared with $1.7 billion in 2011. These amounts reflect the net income reported by the Company during those periods, excluding gains or losses from investments and the disposition of businesses, adjusted for non-cash charges and changes in working capital which relate, primarily, to the timing of payments for accrued liabilities or receipts of assets. The reduction in cash generated from operations is primarily due to the cash refunds of U.S. federal income taxes received in 2011, discussed below. Cash generated from the disposition of businesses is included in investing cash flows.

The Company received $322 million in cash refunds of U.S. federal income taxes during the second quarter of 2011, comprising $212 million from carrying back the net capital loss incurred in 2010 from the sale of Kroll and various other assets, and $110 million from the cash settlement of the IRS audit for the periods 2006 through 2008. The audit settlement primarily reflected the allowance of carry back claims for net operating losses and excess foreign tax credits arising in 2008. The impact on the tax provision of these events was reflected in prior periods and did not impact income tax expense reported in 2011.

On June 11, 2010, the Company resolved the litigation brought by the ARMB on behalf of two Alaska benefit plans against Mercer, relating to work in the period 1992 to 2004. Under the terms of the settlement agreement, Mercer paid $500 million, of which $100 million was covered by insurance.

Pension Related Items

During 2012, the Company contributed $124 million to its U.S. pension plans and $389 million to non-U.S. pension plans, which includes discretionary contributions of $100 million to each of the U.S. and the U.K. plans, compared with $24 million for U.S. plans and $320 million for non-U.S. plans in 2011.

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 under the ERISA guidelines. The pension stabilization provisions included in the "Moving Ahead for Progress in the 21st Century Act", enacted on July 6, 2012, changed the methodology for determining the discount rate used for calculating plan liabilities under ERISA, which determines, in part, the funding requirements. After considering the impact of the pension funding stabilization provisions discussed above, the Company does not expect any contributions will be required to its U.S. tax-qualified plan through the end of 2014. The Company expects to fund approximately $25 million to its non-qualified U.S. pension plans in 2013.

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 82% of non-U.S. plan assets. Contribution rates for non-US plans are generally based on local funding practices and statutory requirements, which may differ significantly from measurements under U.S. GAAP. In the U.K., contributions to defined benefit pension plans are determined through a negotiation process between the Company and the plans' Trustee that typically occurs every three years in conjunction with the actuarial valuation of the plans. This process is governed by U.K. pension regulations. The assumptions that result from the funding negotiations are different from those used for U.S. GAAP and currently result in a lower funded status than under U.S. GAAP. The current funding plan was based on assumptions (including interest rates, inflation, salary increases and

38

mortality) that reflected market conditions as of year-end 2009, was agreed to in early 2011 and forms the basis for the Company's aggregate contributions to the U.K. plans for 2011 through 2013. In 2012, the Company made required contributions of $289 million to its non-U.S. defined benefit pension plans, including amounts called for under the U.K. funding plan. Additionally, the Company made a $100 million discretionary contribution to the U.K. plans. The valuation of the U.K. pension plan at December 31, 2012 that results from the negotiation process described above will determine funding that is expected to become applicable in 2014. Contributions to the U.K. plans typically comprised of a portion related to the current service cost, that is, the benefits earned by employees in the current year, plus an amount intended to reduce, over time, any deficit determined through the Company's negotiations with the Trustee. The Company anticipates contributing approximately $250 million in March 2013 to pre-fund all or a substantial portion of any deficit funding contributions that may be required from 2014 through 2016 as a result of the negotiations with the Trustee. In the aggregate, the Company expects to fund $623 million to its non-U.S. plans in 2013, comprising $171 million to plans outside of the U.K. (including a $70 million discretionary contribution to a Canadian plan in January 2013) and $452 million to the U.K. plans.

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.

The year-over-year change in the funded status of the Company's pension plans is impacted by the variance 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 $1.9 billion and $3.3 billion at December 31, 2012 for the U.S. plans and non-U.S. plans, respectively, compared with $1.7 billion and $3.0 billion at December 31, 2011. The increase is primarily due to the impact of decreases in the discount rates partly offset by actual returns on plan assets in 2012 that were higher than the estimated long-term rate of return on plan assets. In the past several years, the amount of actuarial 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 declined in both the U.S. and the U.K. (the Company's two largest plans) in each of the four years for 2009 to 2012. At the end of 2009, the weighted average discount rate for all plans was 6.0%, declining to 5.6%, 4.9% and 4.4% at the end of 2010, 2011 and 2012, respectively. A decline in the discount rate increases the measured plan liability, resulting in actuarial losses. During 2012, the Company's defined benefit pension plan assets had actual returns of 14.1% and 9.9% in the U.S. and U.K., respectively. During 2011, the Company's defined benefit pension plan assets had actual returns of 5.8%, and 4.8% in the U.S. and U.K., respectively; and in 2010, the actual returns were 14.4% in the U.S. and 13.5% in the U.K. In 2012 and 2010, actuarial losses resulting from declines in the discount rate were partly offset by actual asset returns which exceeded the assumed rates of return in each year. In 2011, both the decline in the discount rate and actual asset returns that were lower than the assumed rates of return contributed to the actuarial losses.

Overall, the Company’s pension expense is expected to increase in 2013 by approximately $30 million before the partly-offsetting impacts on bonuses and other incentive compensation and possible movements in foreign exchange rates. The increase in the expected pension expense in 2013 results primarily from a decline in the discount rates used to measure plan liabilities. Partly offsetting this increase is the impact of an increase in plan assets resulting from both investment returns and contributions.The impact of these higher asset levels is partly offset by a reduction in the weighted average assumed rate of return related to the non-U.S. plans.

The Company’s accounting policies for its defined benefit pension plans, including the selection of and sensitivity to assumptions, are discussed below under Management’s Discussion of Critical Accounting Policies. For additional information regarding the Company’s retirement plans, see Note 8 to the consolidated financial statements.

Financing Cash Flows

Net cash used for financing activities was $633 million in 2012 compared with $1.0 billion of net cash used for financing activities in 2011. The Company reduced outstanding debt by approximately $10 million, $100 million and $550 million in 2012, 2011 and 2010, respectively.

39

Debt

During the first quarter of 2012, the Company repaid its 6.25% fixed rate $250 million senior notes that matured. The Company used proceeds from the issuance of 2.3% five-year $250 million senior notes in the first quarter to fund the maturing notes.

On July 15, 2011, the Company purchased $600 million of outstanding notes comprised of $330 million of its 2014 Notes and $270 million of its 2015 Notes (collectively, the "Notes"). The Company acquired the Notes at fair value plus a tender premium, which exceeded its carrying value. A charge of approximately $72 million was recorded in the Consolidated Statement of Income in the third quarter of 2011 related to the extinguishment of this debt.

The Company used proceeds from the issuance of 4.80% ten-year $500 million senior notes in the third quarter of 2011 and cash on hand to purchase the Notes.

In February 2013, the Company repaid $250 million of maturing senior notes.

Acquisitions

During 2012, the Company paid $30 million of contingent payments related to acquisitions made in prior periods. Remaining estimated future contingent consideration payments of $63 million for acquisitions completed in 2012 and in prior years are recorded in accounts payable and accrued liabilities or other liabilities in the consolidated balance sheet at December 31, 2012.

In the second quarter of 2011, the Company acquired the remaining minority interest of a previously majority-owned entity for total cash consideration of $8 million.

In the first quarter of 2011, the Company paid deferred purchase consideration of $13 million related to the purchase in 2009 of the minority interest of a previously controlled entity.

Credit Facilities

The Company and certain of its subsidiaries maintain a $1.0 billion multi-currency five-year unsecured revolving credit facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. This facility requires the Company to maintain certain coverage and leverage ratios which are tested quarterly. There were no borrowings under this facility at December 31, 2012.

In December 2012 the Company closed on a $50 million, 3-year delayed draw term loan facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. The facility requires the Company to maintain coverage ratios and leverage ratios consistent with the revolving credit facility discussed above. There were no borrowings under this facility at December 31, 2012.

The Company’s senior debt is currently rated Baa2 by Moody’s and BBB by Standard & Poor’s. The Company’s short-term debt is currently rated P-2 by Moody’s and A-2 by Standard & Poor’s. The Company carries a stable outlook from Moody’s and Standard & Poor’s.

The Company also maintains other credit facilities, guarantees and letters of credit with various banks, primarily related to operations located outside the United States, aggregating $247 million at December 31, 2012 and $248 million at December 31, 2011. There were no outstanding borrowings under these facilities.

Share Repurchases

During 2012, the Company repurchased approximately 6.9 million shares of its common stock for total consideration of approximately $230 million at an average price per share of $33.36. The Company remains authorized to repurchase additional shares of its common stock up to a value of $323 million. There is no time limit on this authorization. During 2011, the Company repurchased approximately 12.3 million shares of its common stock for total consideration of approximately $361 million at an average price per share of $29.44.

40

Dividends

The Company paid total dividends of $497 million in 2012 ($0.90 per share), $480 million in 2011 ($0.86 per share) and $452 million in 2010 ($0.81 per share).

Investing Cash Flows

Net cash used for investing activities amounted to $583 million in 2012 compared with $457 million used for investing activities in 2011. The Company made 15 acquisitions in 2012. Cash used for these acquisitions, net of cash acquired was $230 million. In addition, in 2012, the Company paid $59 million of deferred purchase consideration related to acquisitions made in prior years and $3 million for the purchase of other intangible assets. Remaining deferred cash payments of approximately $42 million for acquisitions completed in 2012 and in prior years are recorded in accounts payable and accrued liabilities or other liabilities in the consolidated balance sheet at December 31, 2012.

The Company made 12 acquisitions in 2011. Cash used for these acquisitions, net of cash acquired, was $160 million compared with $427 million used for acquisitions in 2010. In addition, the Company recorded a liability of $33 million for estimated contingent purchase consideration related to the acquisitions completed in 2011. In 2011, the Company also paid $11 million for deferred purchase consideration, $62 million into escrow for future acquisitions and $4 million for the purchase of other intangible assets. In 2010, in addition to the cash paid, the Company issued approximately 7.6 million shares of common stock with an acquisition date value of $183 million, and also paid $60 million of deferred purchase consideration, $3 million for other intangible assets and $2 million of contingent purchase consideration related to acquisitions made in prior years.

Cash provided by the sale of securities was $6 million for the periods ended December 31, 2012 and 2011, respectively.

The Company’s additions to fixed assets and capitalized software, which amounted to $320 million in 2012 and $280 million in 2011, primarily relate to computer equipment purchases, the refurbishing and modernizing of office facilities and software development costs.

The Company has committed to potential future investments of approximately $40 million in private equity funds that invest primarily in financial services companies. Substantially all invested assets in Trident II were harvested in the first quarter of 2013 and the fund is expected to wind down. The Company expects to receive approximately $100 million related to its Trident II investment in 2013.

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, 2012:

	Payment due by Period
Contractual Obligations (In millions of dollars)	Total		Within 1 Year		1-3 Years		4-5 Years		After 5 Years
Current portion of long-term debt	$	260	$	260	$	—	$	—	$	—
Long-term debt	2,664		—		821		273		1,570
Interest on long-term debt	1,309		159		287		209		654
Net operating leases	2,489		355		583		433		1,118
Service agreements	374		136		120		78		40
Other long-term obligations	144		32		103		7		2
Purchase commitments	47		32		15		—		—
Total	$	7,287	$	974	$	1,929	$	1,000	$	3,384

The above does not include the liability for unrecognized tax benefits of $117 million as the Company is unable to reasonably predict the timing of settlement of these liabilities, other than approximately $12 million that may become payable during 2013. The above does not include the indemnified liabilities discussed in Note 15 as the Company is unable to reasonably predict the timing of settlement of these liabilities. The above does not include net pension liabilities of approximately $1.8 billion because the

41

timing and amount of ultimate payment of such liability is dependent upon future events, including, but not limited to, future returns on plan assets, and changes in the discount rate used to measure the liabilities. The amounts of estimated future benefits payments to be made from plan assets are disclosed in Note 8 to the consolidated financial statements. In 2013, the Company expects to contribute approximately $25 million and $623 million to its U.S. and non-U.S. pension plans, respectively.

Management’s Discussion of Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and judgments that affect reported amounts of assets, liabilities, revenue and expenses, and disclosure of contingent assets and liabilities. Management considers the policies discussed below to be critical to understanding the Company’s financial statements because their application places the most significant demands on management’s judgment, and requires management to make estimates about the effect of matters that are inherently uncertain. Actual results may differ from those estimates.

Legal and Other Loss Contingencies

The Company and its subsidiaries are subject to numerous claims, lawsuits and proceedings including claims for errors and omissions. GAAP requires that a liability be recorded when a loss is both probable and reasonably estimable. Significant management judgment is required to apply this guidance. The Company utilizes case level reviews by inside and outside counsel, an internal actuarial analysis and other analyses to estimate potential losses. The liability is reviewed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable. Given the unpredictability of E&O claims and of litigation that could flow from them, it is possible that an adverse outcome in a particular matter could have a material adverse effect on the Company’s businesses, results of operations, financial condition or cash flow in a given quarterly or annual period.

In addition, to the extent that insurance coverage is available, significant management judgment is required to determine the amount of recoveries that are probable of collection under the Company’s various insurance programs.

Retirement Benefits

The Company maintains qualified and non-qualified defined benefit pension and defined contribution plans for its eligible U.S. employees and a variety of defined benefit and defined contribution plans for its eligible non-U.S. employees. The Company’s policy for funding its tax qualified defined benefit retirement plans is to contribute amounts at least sufficient to meet the funding requirements set forth in U.S. and applicable foreign laws.

The Company recognizes the funded status of its over-funded defined benefit pension and retiree medical plans as a net benefit plan asset and its unfunded and underfunded plans as a net benefit plan liability. The gains or losses and prior service costs or credits that have not been recognized as components of net periodic costs are recorded as a component of Accumulated Other Comprehensive Income (“AOCI”), net of tax, in the Company’s consolidated balance sheets. The gains and losses that exceed specified corridors are amortized prospectively out of AOCI over a period that approximates the average remaining service period of active employees, or for plans in which substantially all the participants are inactive, over the remaining life expectancy of the inactive employees.

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. Significant assumptions used in the calculation of net periodic pension costs and pension liabilities are disclosed in Note 8 to the consolidated financial statements. The Company believes the assumptions for each plan are reasonable and appropriate and will continue to evaluate assumptions at least annually and adjust them as appropriate. Based on its current assumptions, the Company expects pension expense in 2013 to increase approximately $30 million compared with 2012 before partly-offsetting impacts of bonuses and other incentive compensation and possible movements in foreign exchange rates.

42

Future pension expense or credits will depend on plan provisions, future investment performance, future assumptions and various other factors related to the populations participating in the pension plans. 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 88% of total pension plan liabilities, as follows:

	0.5 Percentage Point Increase						0.5 Percentage Point Decrease
(In millions of dollars)	U.S.			U.K.			U.S.		U.K.
Assumed Rate of Return on Plan Assets	$	(18	)	$	(35	)	$	18	$	35
Discount Rate	$	(20	)	$	(25	)	$	20	$	25

Changing the discount rate and leaving the other assumptions constant may not be representative of the impact on expense, because the long-term rates of inflation and salary increases are often correlated with the discount rate. Changes in these assumptions will not necessarily have a linear impact on the net periodic pension cost.

The Company contributes to certain health care and life insurance benefits provided to its retired employees. The cost of these post-retirement benefits for employees in the U.S. is accrued during the period up to the date employees are eligible to retire, but is funded by the Company as incurred. The key assumptions and sensitivity to changes in the assumed health care cost trend rate are discussed in Note 8 to the consolidated financial statements.

Income Taxes

The Company's 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 effective tax rate and in evaluating uncertain tax positions. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The evaluation of a tax position is a two-step process. The first step involves recognition. The Company determines whether it is more likely than not that a tax position will be sustained upon tax examination, including resolution of any related appeals or litigation, based on only the technical merits of the position. The technical merits of a tax position derive from both statutory and judicial authority (legislation and statutes, legislative intent, regulations, rulings, and case law) and their applicability to the facts and circumstances of the tax position. If a tax position does not meet the more likely than not recognition threshold, the benefit of that position is not recognized in the financial statements. The second step is measurement. A tax position that meets the more likely than not recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate resolution with a taxing authority.

Uncertain tax positions are evaluated based upon the facts and circumstances that exist at each reporting period and involve significant management judgment. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition, and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue.

Tax law requires 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 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 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. In assessing the need for and amount of a valuation allowance for deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized and adjusts the valuation allowance accordingly. The Company evaluates all significant available positive and

43

negative evidence, including the existence of losses in recent years and its forecast of future taxable income by jurisdiction, in assessing the need for a valuation allowance. The Company also considers tax-planning strategies that would result in realization of deferred tax assets, and the presence of taxable income in prior period tax filings in jurisdictions that allow for the carryback of tax attributes pursuant to the applicable tax law. The underlying assumptions the Company uses in forecasting future taxable income require significant judgment and take into account the Company's recent performance. The ultimate realization of deferred tax assets is dependent on the generation of future taxable income during the periods in which temporary differences or carry-forwards are deductible or creditable. Valuation allowances are established for deferred tax assets when it is estimated that it is more likely than not that future taxable income will be insufficient to fully use a deduction or credit in that jurisdiction.

Fair Value Determinations

Investment Valuation—The Company holds investments in private companies as well as certain private equity funds. Certain investments, primarily investments in private equity funds, are accounted for using the equity method. Although not directly recorded in the Company’s consolidated balance sheets, the Company defined benefit pension plans hold investments of approximately $12.2 billion. The fair value of these investments determines, in part, the over-or under-funded status of those plans, which is included in the Company’s consolidated balance sheets. The Company periodically reviews the carrying value of its investments to determine if any valuation adjustments are appropriate under the applicable accounting pronouncements. The Company bases its review on the facts and circumstances as they relate to each investment. Fair value of investments in private equity funds is determined by the funds’ investment managers. Factors considered in determining the fair value of private equity investments include: implied valuation of recently completed financing rounds that included sophisticated outside investors; performance multiples of comparable public companies; restrictions on the sale or disposal of the investments; trading characteristics of the securities; and the relative size of the holdings in comparison to other private investors and the public market float. In those instances where quoted market prices are not available, particularly for equity holdings in private companies, or formal restrictions limit the sale of securities, significant management judgment is required to determine the appropriate value of the Company’s investments. The Company reviews with the fund manager the appropriateness of valuation results for significant private equity investments.

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 goodwill impairment test for each of its reporting units during the third quarter of each year. The Company adopted new accounting guidance in the third quarter of 2011. Under this guidance, a company may first assess qualitative factors to determine whether it is necessary to perform the goodwill impairment test. If, as a result of this qualitative assessment, a company determines the fair value of a reporting unit is more likely than not lower than its carrying value, a step 1 impairment assessment must be performed. The Company considered the totality of numerous factors, which included that the fair value of each reporting unit exceeded its carrying value by a substantial margin in its most recent estimate of reporting unit fair values, whether significant acquisitions or dispositions occurred which might alter the fair values 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.

Based on its qualitative evaluation, the Company concluded that a two-step goodwill impairment test was not required in 2012.

Share-based Payment

The guidance for accounting for share-based payments requires, among other things, that the estimated fair value of stock options be charged to earnings. Significant management judgment is required to determine the appropriate assumptions for inputs such as volatility and expected term necessary to estimate option values. In addition, management judgment is required to analyze the terms of the plans and awards granted thereunder to determine if awards will be treated as equity awards or liability awards, as defined by the accounting guidance.

44

As of December 31, 2012, there was $18 million of unrecognized compensation cost related to stock option awards. The weighted-average periods over which the costs are expected to be recognized is 1.3 years. Also as of December 31, 2012, there was $135 million of unrecognized compensation cost related to the Company’s restricted stock, restricted stock unit and deferred stock unit awards.

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

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

The Company has historically managed its net exposure to interest rate changes by utilizing a mixture of variable and fixed rate borrowings to finance the Company’s asset base. In February 2011, the Company entered into two 3.5-year interest rate swaps to hedge changes in the fair value of the first $250 million of its 5.375% senior notes due in 2014. Under the terms of the swaps, the counter-parties will pay the Company a fixed rate of 5.375% and the Company will pay interest at a floating rate of three-month LIBOR plus a fixed spread of 3.726%. The swaps are designated as fair value hedging instruments and are deemed to be perfectly effective in accordance with applicable accounting guidance.

Interest income generated from the Company’s cash investments as well as invested fiduciary funds will vary with the general level of interest rates.

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

(In millions of dollars)	December 31, 2012
Cash and cash equivalents invested in money market funds, certificates of deposit and time deposits	$2,301
Fiduciary cash and investments	$3,992

Based on the above balances, if short-term interest rates increased or decreased by 10%, or 10 basis points, over the course of the year, annual interest income, including interest earned on fiduciary funds, would increase or decrease by approximately $4 million.

In addition to interest rate risk, our cash investments and fiduciary fund investments are subject to potential loss of value due to counter-party credit risk. To minimize this risk, the Company and its subsidiaries invest pursuant to a Board approved investment policy. The policy mandates the preservation of principal and liquidity and requires broad diversification with counter-party limits assigned based primarily on credit rating and type of investment. The Company carefully monitors its cash and fiduciary fund investments and will further restrict the portfolio as appropriate to market conditions. The majority of cash and fiduciary fund investments are invested in short-term bank deposits and liquid money market funds.

Foreign Currency Risk

The translated values of revenue and expense from the Company’s international operations are subject to fluctuations due to changes in currency exchange rates. The non-U.S. based revenue that is exposed to foreign exchange fluctuations is approximately 56% 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, the U.S. dollar translation of both the revenues and expenses, as well as the potentially offsetting movements of various currencies against the U.S. dollar, generally tends to mitigate the impact on net operating income of foreign currency risk. The Company estimates that a 10% movement of major foreign currencies (Euro, Sterling, Australian dollar and Canadian dollar) in the same direction against the U.S. dollar that held constant over the course of the year would increase or decrease full year operating income by approximately $45 million.

46

Equity Price Risk

The Company holds investments in both public and private companies, and certain private equity funds that invest primarily in financial services companies. Non-publicly traded investments of $16 million are accounted for using the cost method and $131 million are accounted for using the equity method. The investments that are classified as available for sale or that are not publicly traded are subject to risk of changes in market value, which if determined to be other than temporary, could result in realized impairment losses. The Company periodically reviews the carrying value of such investments to determine if any valuation adjustments are appropriate under the applicable accounting pronouncements.

Other

A number of lawsuits and regulatory proceedings are pending. See Note 15 to the consolidated financial statements included elsewhere in this report.

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 organizational structure, the Company’s two business segments are Risk and Insurance Services and Consulting.

The Risk and Insurance Services segment provides risk management and insurance broking, reinsurance broking and insurance program management services for businesses, public entities, insurance companies, associations, professional services organizations, and private clients. The Company conducts business in this segment through Marsh and Guy Carpenter.

The Company conducts business in its Consulting segment through two main business groups. Mercer provides consulting expertise, advice, services and solutions in the areas of talent, health, retirement and investments. Oliver Wyman Group provides specialized management and economic and brand consulting services.

Acquisitions impacting the Risk and Insurance Services and Consulting segments are discussed in Note 4 to the consolidated financial statements.

On August 3, 2010, the Company completed the sale of Kroll, the Company’s former Risk Consulting & Technology segment, to Altegrity, Inc. (“Altegrity”) for cash consideration of $1.13 billion. In the first quarter of 2010, Kroll completed the sale of Kroll Laboratory Specialists (“KLS”). The gain on the sale of Kroll and related tax benefits and the after-tax loss on the sale of KLS, along with Kroll’s, and KLS’s 2010 results of operations are included in discontinued operations in 2010.

With the sale of Kroll in August 2010, along with other dispositions between 2008 and 2010, the Company has divested its entire Risk Consulting and Technology Segment. The Company has “continuing involvement” in certain Corporate Advisory and Restructuring businesses (“CARG”) that were disposed of in 2008. The runoff of the CARG businesses is being managed by the Company's corporate departments and financial results of these entities are included in “Corporate” for segment reporting purposes.

Principles of Consolidation:  The accompanying consolidated financial statements include all wholly-owned and majority-owned subsidiaries. All significant inter-company transactions and balances have been eliminated.

Fiduciary Assets and Liabilities:  In its capacity as an insurance broker or agent, the Company generally collects premiums from insureds and, after deducting its commissions, remits the premiums to the respective insurance underwriters. The Company also collects claims or refunds from underwriters on behalf of insureds. Unremitted insurance premiums and claims proceeds are held by the Company in a fiduciary capacity. Risk and Insurance Services revenue includes interest on fiduciary funds of $39 million, $47 million and $45 million in 2012, 2011 and 2010, respectively. The Consulting segment recorded fiduciary interest income of $4 million in each of 2012 , 2011 and 2010. Since fiduciary assets are not available for corporate use, they are shown in the consolidated balance sheets as an offset to fiduciary liabilities.

Net uncollected premiums and claims and the related payables amounted to $9.1 billion and $9 billion at December 31, 2012 and 2011, 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. Net uncollected premiums and claims and the related payables are, therefore, 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.

53

Mercer manages approximately $16 billion of assets in trusts or funds for which Mercer’s management or trustee fee is considered a variable interest. Mercer is not the primary beneficiary of these trusts or funds. Mercer’s only variable interest in any of these trusts or funds is its unpaid fees, if any. Mercer’s maximum exposure to loss of its interests is, therefore, limited to collection of its fees.

Revenue:  Risk and Insurance Services revenue includes insurance commissions, fees for services rendered and interest income on certain fiduciary funds. Insurance commissions and fees for risk transfer services generally are recorded as of the effective date of the applicable policies or, in certain cases (primarily in the Company's reinsurance broking operations), as of the effective date or billing date, whichever is later. A reserve for policy cancellation is provided based on historic and current data on cancellations. Fees for non-risk transfer services provided to clients are recognized over the period in which the services are provided, using a proportional performance model. Fees resulting from achievement of certain performance thresholds are recorded when such levels are attained and such fees are not subject to forfeiture.

As part of the sale of MMC Capital in 2005, the Company retained the right to receive certain performance fees related to the Trident II and Trident III private equity partnerships. The Company recognizes performance fee income when such fees are no longer subject to forfeiture, which may take a number of years to resolve. The Company has deferred the recognition of income related to such performance fees of $78 million and $74 million at December 31, 2012 and 2011, respectively. This income is based on the investment performance over the life of each private equity fund, and future declines in fund performance from current levels may result in the forfeiture of such revenue. In the first quarter of 2013, Trident II sold substantially all of the remaining assets of the fund and the fund will wind down. As a result, approximately $15 million of the deferred performance fees will be recognized as part of investment income.

Consulting revenue includes fees paid by clients for advice and services and commissions from insurance companies for the placement of individual and group contracts. Fee revenue for engagements where remuneration is based on time plus out-of-pocket expenses is recognized based on the amount of time consulting professionals expend on the engagement. For fixed fee engagements, revenue is recognized using a proportional performance model. Revenue from insurance commissions not subject to a fee arrangement is recorded over the effective period of the applicable policies. Revenues for asset based fees are recognized on an accrual basis by applying the daily/monthly rate as contractually agreed with the client to the applicable net asset value. On a limited number of engagements, performance fees may also be earned for achieving certain pre-determined performance criteria. Such fees are recognized when the performance criteria have been achieved and agreed to by the client. Expenses incurred by professional staff in the generation of revenue are billed to the client and included in 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 of approximately $250 million related to regulatory requirements outside the U.S. or as collateral under captive insurance arrangements.

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

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

54

The components of fixed assets are as follows:

December 31,
(In millions of dollars)	2012			2011
Furniture and equipment	$	1,168		$	1,101
Land and buildings	412			405
Leasehold and building improvements	811			767
	2,391			2,273
Less-accumulated depreciation and amortization	(1,582		)	(1,469		)
	$	809		$	804

Investment Securities:  The Company holds investments primarily in private companies and certain private equity funds.

Certain investments, primarily investments in private equity funds, are accounted for under the equity method 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 securities within the fund are carried at fair value. The Company records its proportionate share of the change in fair value of the funds in earnings which amounted to gains of $33 million, $10 million and $32 million in 2012, 2011 and 2010, respectively. Securities recorded using the equity method are included in other assets in the consolidated balance sheets.

The Company has an investment in Trident II limited partnership, a private equity investment fund. At December 31, 2012, the Company’s investment in Trident II was approximately $78 million, reflected in other assets in the consolidated balance sheet. In the first quarter of 2013, Trident II sold substantially all remaining assets and the fund will wind down. The Company expects to receive approximately $100 million in cash proceeds related to this sale in 2013.

Gains or losses recognized in earnings from the investment securities, including the performance fees discussed above, are included in investment income in the consolidated statements of income. Costs related to management of the Company’s investments, including incentive compensation partially derived from investment income and (loss), are recorded in operating expenses.

Goodwill and Other Intangible Assets:  Goodwill represents acquisition costs in excess of the fair value of net assets acquired. Goodwill is reviewed at least annually for impairment. The Company performs an annual impairment test for each of its reporting units during the third quarter of each year. When a step 1 test is performed, fair values of the reporting units are estimated using either a market approach or a discounted cash flow model. Carrying values for the reporting units are based on balances at the prior quarter end and include directly identified assets and liabilities as well as an allocation of those assets and liabilities not recorded at the reporting unit level. As discussed in Note 6, the Company assesses qualitative factors to determine if a step 1 assessment is necessary. Other intangible assets, which primarily consist of customer lists, that are not deemed to have an indefinite life are amortized over their estimated lives and reviewed for impairment upon the occurrence of certain triggering events in accordance with applicable accounting literature. The Company had no indefinite lived identified intangible assets at December 31, 2012 or 2011.

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 three to ten 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 $278 million and $244 million, net of accumulated amortization of $691 million and $619 million at December 31, 2012 and 2011, respectively, are included in other assets in the consolidated balance sheets.

Legal and Other Loss Contingencies:  The Company and its subsidiaries are subject to numerous claims, lawsuits and proceedings including claims for errors and omissions ("E&O"). GAAP requires that

55

a liability be recorded when a loss is both probable and reasonably estimable. Significant management judgement is required to apply this guidance. The Company utilizes case level reviews by inside and outside counsel, an internal actuarial analysis and other analyses to estimate potential losses. The liability is reviewed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable. Given the unpredictability of E&O claims and of litigation that could flow from them, it is possible that an adverse outcome in a particular matter could have a material adverse effect on the Company’s businesses, results of operations, financial condition or cash flow in a given quarterly or annual period.

In addition, to the extent that insurance coverage is available, significant management judgment is required to determine the amount of recoveries that are probable of collection under the Company’s various insurance programs.

The legal and other contingent liabilities described above are not discounted.

Income Taxes:  The Company's effective tax rate reflects its income, statutory tax rates and tax planning in the various jurisdictions in which it operates. Significant judgment is required in determining the annual effective tax rate 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 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. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition, and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Tax law requires items be included in the Company's tax returns at different times than the items are reflected in the financial statements. As a result, the annual tax expense reflected in the consolidated statements of income is different than that reported in the income tax returns. Some of these differences are permanent, such as expenses that are not deductible in the returns, and some differences are temporary and reverse over time, such as depreciation expense. Temporary differences create deferred tax assets and liabilities. Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns in future years for which benefit has already been recorded in the financial statements. Valuation allowances are established for deferred tax assets when it is estimated that future taxable income will be insufficient to use a deduction or credit in that jurisdiction. Deferred tax liabilities generally represent tax expense recognized in the financial statements for which payment has been deferred, or expense for which a deduction has been taken already in the tax return but the expense has not yet been recognized in the financial statements.

Derivative Instruments:  All derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. 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.

56

Concentrations of Credit Risk:  Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, commissions and fees receivable and insurance recoverables. The Company maintains a policy providing for the diversification of cash and cash equivalent investments and places its investments in a large number of high quality financial institutions to limit the amount of credit risk exposure. Concentrations of credit risk with respect to receivables are generally limited due to the large number of clients and markets in which the Company does business, as well as the dispersion across many geographic areas.

Per Share Data: Under the accounting guidance which applies to the calculation of earnings per share (“EPS”) for share-based payment awards with rights to dividends or dividend equivalents, unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and should be included in the computation of basic and dilutive EPS using the two-class method.

Basic net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income attributable to common shares by the weighted average number of outstanding shares of the Company’s common stock.

Diluted net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income attributable to common shares by the weighted average number of outstanding shares of the Company’s common stock, which have been adjusted for the dilutive effect of potentially issuable common shares (excluding those that are considered participating securities). The diluted earnings per share calculation reflects the more dilutive effect of either (a) the two-class method that assumes that the participating securities have not been exercised or (b) the treasury stock method. Reconciliation of the applicable income components used for diluted earnings per share and basic weighted average common shares outstanding to diluted weighted average common shares outstanding is presented below.

There were 32.0 million, 38.9 million and 43.4 million stock options outstanding as of December 31, 2012, 2011 and 2010, respectively.

Other Significant Matters Impacting Results in Prior Periods: In June 2010, the Company settled a lawsuit brought by the Alaska Retirement Management Board (“ARMB”) against Mercer. Under the terms of the settlement agreement, Mercer paid $500 million, of which $100 million was covered by insurance, and recognized a charge of $400 million in the second quarter of 2010.

Estimates:  The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may vary from those estimates.

New Accounting Pronouncements:  In the first quarter of 2012, the Company adopted new accounting guidance related to the presentation of Comprehensive Income. The new guidance gives an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The guidance did not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income.

On February 5, 2013, the FASB issued new accounting guidance that adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. The Company is required to

58

implement this new guidance for the reporting period ended March 31, 2013. Other than enhanced disclosure, the adoption of this new guidance is not expected to have a material effect on the Company's financial statements.

In January 2012, the Company adopted guidance issued by the FASB on accounting and disclosure requirements related to fair value measurements. The guidance expands the disclosures on Level 3 inputs by requiring quantitative disclosure of the unobservable inputs and assumptions, as well as description of the valuation processes, the sensitivity of the fair value to changes in unobservable inputs and the hierarchy classification, valuation techniques, and inputs for assets and liabilities whose fair value is only disclosed in the footnotes.

In January 2011, the Company adopted guidance issued by the FASB on revenue recognition regarding multiple-deliverable revenue arrangements. Other than enhanced disclosure, the adoption of this new guidance did not have a material effect on the Company's financial statements.

In January 2011, the Company adopted guidance issued by the FASB which establishes a revenue recognition model for contingent consideration that is payable upon the achievement of an uncertain future event, referred to as a milestone. The scope of this guidance is limited to research or development arrangements and requires an entity to record the milestone payment in its entirety in the period received if the milestone meets all the necessary criteria to be considered substantive. However, entities would not be precluded from making an accounting policy election to apply another appropriate accounting policy that results in the deferral of some portion of the arrangement consideration. The adoption of this new guidance did not have a material impact on the Company’s financial statements.

Reclassifications: Certain reclassifications have been made to prior period amounts to conform with current year presentation, in particular with regard to combining income taxes receivable with other receivables on the consolidated balance sheets.

59

$152 million, $165 million and $174 million for the years ended December 31, 2012, 2011 and 2010, respectively.

The consolidated statement of cash flows includes the cash flow impact of discontinued operations in each cash flow category. The cash flow impact of discontinued operations from the operating, financing and investing cash flow categories is as follows:

4.     Acquisitions

The Company’s acquisitions have been accounted for as purchases. Net assets and results of operations are included in the Company’s consolidated financial statements commencing at the respective effective purchase dates. In connection with acquisitions, the Company records the estimated value of the net tangible assets purchased and the value of the identifiable intangible assets purchased, which typically consist of purchased customer lists, trademarks and non-compete agreements. The valuation of

61

purchased intangible assets involves significant estimates and assumptions. Any change in assumptions could affect the carrying value of such intangible assets.

During 2012, Marsh completed the following twelve acquisitions:

• January - Marsh acquired Alexander Forbes' South African brokerage operations, including Alexander Forbes Risk Services and related ancillary operations and insurance broking operations in Botswana and Namibia to expand Marsh's presence in Africa. Marsh subsequently closed the acquisitions of the Alexander Forbes operations in Uganda, Malawi and Zambia.

• March - Marsh & McLennan Agency business ("MMA") acquired KSPH, LLC, a middle-market employee benefits agency based in Virginia, and Marsh acquired Cosmos Services (America) Inc., the U.S. insurance brokerage subsidiary of ITOCHU Corp., which specializes in commercial property/casualty, personal lines, and employee benefits brokerage services to U.S. subsidiaries of Japanese companies.

• June - MMA acquired Progressive Benefits Solutions, an employee benefits agency based in North Carolina, and Security Insurance Services, Inc., a Wisconsin-based insurance agency which offers property/casualty and employee benefits products and services to individuals and businesses.

• August - MMA acquired Rosenfeld-Einstein, a South Carolina-based employee benefits service provider, and Eidson Insurance, a property/casualty and employee benefits services firm located in Florida.

• October - MMA acquired Howalt+McDowell, a South Dakota-based agency which offers property casualty, surety, personal protection and employee benefits insurance to individuals and businesses, and The Protector Group Insurance Agency, a Massachusetts-based agency which provides property casualty, employee benefits services, personal insurance and individual financial services.

• December - MMA acquired McGraw Wentworth, a Michigan-based company providing consulting services to mid-sized organizations, and Liscomb Hood Mason, a Minnesota-based company providing property/casualty and employee benefits products and services.

The MMA acquisitions were made to expand Marsh's presence in the U.S. middle-market business.

During 2012, Mercer completed the following three acquisitions:

• February - Mercer acquired the remaining 49% of Yokogawa-ORC, a global mobility firm based in Japan, which was previously accounted for under the equity method, and Pensjon & Finans, a leading Norway-based financial investment and pension consulting firm.

• March - Mercer acquired REPCA, a France-based broking and advisory firm for employer health and benefits plans.

Total purchase consideration for acquisitions made during 2012 was $360 million, which consisted of cash paid of $252 million, deferred purchase and estimated contingent consideration of $46 million, and cash held in escrow of $62 million at December 31, 2011 that was released in the first quarter of 2012. Contingent consideration arrangements are primarily based on EBITDA and revenue targets over 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 2012, the Company also paid $59 million of deferred purchase consideration and $30 million of contingent consideration related to acquisitions made in prior years. In addition, the Company paid $3 million to purchase other intangible assets during 2012.

Prior Year Acquisitions

During 2011, the Company made seven acquisitions in its Risk and Insurance Services segment and five in its Consulting segment. In January 2011, Marsh acquired RJF Agencies, Inc., an independent insurance broking firm in the Midwest. In February 2011, Marsh acquired Hampton Roads Bonding, a surety bonding agency for commercial, road, utility, maritime and government contractors in the state of Virginia, and the Boston office of Kinloch Consulting Group, Inc. In July 2011, Marsh acquired Prescott Pailet Benefits, an employee benefits broker in the state of Texas. In October 2011, Marsh acquired the employee benefits division of Kaeding, Ernst & Co, a Massachusetts-based employee benefits, life insurance and financial planning consulting firm. In November 2011, Marsh acquired Gallagher & Associates, Inc., a property and casualty insurance agency based in Minnesota. In November 2011, Marsh acquired Seitlin Insurance, an insurance firm based in South Florida. These acquisitions were made to expand Marsh’s share in the middle-market through Marsh & McLennan Agency.

In January 2011, Mercer acquired Hammond Associates, an investment consulting company for endowments and foundations in the U.S. In June 2011, Mercer acquired Evaluation Associates LLC, an investment consulting firm. In July 2011, Mercer acquired Mahoney Associates, a health and benefits advisory firm based in South Florida. In August 2011, Mercer acquired Censeo Corporation, a human resource consulting firm based in Florida. In December 2011, Mercer acquired Alicia Smith & Associates, a Medicaid policy consulting firm based in Washington, D.C.

Total purchase consideration for the 2011 acquisitions was $197 million which consisted of cash paid of $164 million and deferred and estimated contingent consideration of $33 million. Contingent consideration arrangements are primarily based on EBITDA and revenue targets over 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. The Company also paid $27 million of deferred purchase and contingent consideration related to acquisitions made in prior years. In addition, the Company paid $4 million to purchase other intangible assets during 2011.

63

In the second quarter of 2011, Marsh acquired the remaining minority interest of a previously majority owned entity for total purchase consideration of $8 million and accounted for this acquisition under the accounting guidance for consolidations and non-controlling interests. This guidance requires that changes in a parent’s ownership interest while retaining financial controlling interest in a subsidiary be accounted for as an equity transaction. Stepping up the acquired assets to fair value or the recording of goodwill is not permitted. Therefore, the Company recorded a decrease to additional paid-in capital in 2011 of $2 million related to this transaction.

In the first quarter of 2011, the Company paid deferred purchase consideration of $13 million related to the purchase in 2009 of the minority interest of a previously controlled entity.

Pro-Forma Information

While the Company does not believe its acquisitions are material in the aggregate, the following unaudited pro-forma financial data gives effect to the acquisitions made by the Company during 2012 and 2011. In accordance with accounting guidance related to pro-forma disclosures, the information presented for current year acquisitions is as if they occurred on January 1, 2011 and reflects acquisitions made in 2011 as if they occured on January 1, 2010. The pro-forma information adjusts for the effects of amortization of acquired intangibles. The unaudited pro-forma financial data is presented for illustrative purposes only and is not necessarily indicative of the operating results that would have been achieved if such acquisitions had occurred on the dates indicated, nor is it necessarily indicative of future consolidated results.

	Years Ended December 31,

– Net income attributable to the Company	$	2.14	$	1.81	$	1.57

The consolidated statements of income for 2012 include approximately $113 million of revenue and $21 million of net operating income, respectively, related to acquisitions made during 2012.

5.     Discontinued Operations

As part of the disposal transactions for Putnam and Kroll, the Company provided certain indemnities, primarily related to pre-transaction tax uncertainties and legal contingencies. In accordance with applicable accounting guidance, liabilities were established related to these indemnities at the time of the sales and reflected as a reduction of the gain on disposal. Discontinued operations includes charges or credits resulting from the settlement or resolution of the indemnified matters, as well as adjustments to the liabilities related to such matters. Discontinued operations in 2011 includes credits of$50 millionfrom the resolution of certain legal matters and insurance recoveries, as well as the settlement of tax audits and the expiration of the statutes of limitations related to certain of the indemnified matters, primarily with respect to Putnam.

Marsh's BPO business, previously part of the Marsh U.S. Consumer business, provided policy, claims, call center and accounting operations on an outsourced basis to life insurance carriers. Marsh invested in a technology platform that was designed to make the Marsh BPO business scalable and more efficient.

64

During 2011, Marsh decided that it would cease investing in the technology platform and instead exit the business via a sale. In the fourth quarter of 2011, management initiated a plan to sell the Marsh BPO business, which was completed in August 2012. The Company wrote off capitalized software of $17 million, net of tax, which is included in discontinued operations in 2011.

In the first quarter of 2010, Kroll completed the sale of KLS and on August 3, 2010, the Company completed the sale of Kroll to Altegrity.

Kroll’s results of operations are reported as discontinued operations in the Company’s consolidated statement of income for the portion of 2010 prior to Kroll's disposal. The year ended 2010 also includes the gain on the sale of Kroll and related tax benefits and the loss on the sale of KLS, which includes the tax provision of $36 million on the sale.

The Company’s tax basis in its investment in the stock of Kroll at the time of sale exceeded the recorded amount primarily as a result of prior impairments of goodwill recognized for financial reporting, but not tax. A $265 million deferred tax benefit was recorded in discontinued operations in 2010 as a result of the sale of Kroll.

Summarized Statements of Income data for discontinued operations is as follows:

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 test for each of its reporting units during the third quarter of each year. In accordance with applicable accounting guidance, the Company assesses qualitative factors to determine whether it is necessary to perform the two-step goodwill impairment test. The Company considered the numerous factors, which included that the fair value of each reporting unit exceeded its carrying value by a substantial margin in its most recent estimate of reporting unit fair values, whether significant acquisitions or dispositions occurred which might alter the fair values of its reporting units, macroeconomic conditions and their potential impact on reporting unit fair values, actual performance

65

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 evaluation in the third quarter of 2012 and concluded that a two-step goodwill impairment test was not required in 2012 and that goodwill was not impaired.

Other intangible assets that are not deemed to have an indefinite life are amortized over their estimated lives and reviewed for impairment upon the occurrence of certain triggering events in accordance with applicable accounting literature.

Changes in the carrying amount of goodwill are as follows:

(In millions of dollars)	2012		2011
Balance as of January 1, as reported	$	6,562	$	6,420

U.S. Federal income taxes are not provided on temporary differences with respect to investments in foreign subsidiaries that are essentially permanent in duration, which at December 31, 2012 amounted to approximately $4.3 billion. The determination of the unrecognized deferred tax liability with respect to these investments is not practicable.

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,	2012		2011		2010
U.S. Federal statutory rate	35.0	%	35.0	%	35.0	%
U.S. state and local income taxes—net of U.S. Federal income tax benefit	1.9		1.6		1.9
Differences related to non-U.S. operations	(6.1	)	(6.5	)	(9.5	)
Other	(1.8	)	—		(0.9	)
Effective tax rate	29.0	%	30.1	%	26.5	%

The Company’s consolidated tax rate was 29.0%, 30.1% and 26.5% in 2012, 2011 and 2010, respectively. The tax rate in each year reflects foreign operations, which are taxed at rates lower than the U.S. statutory tax rate.

Valuation allowances had net increases of $23 million and decreases of $1 million in 2012 and 2011, respectively. During the respective years, adjustments of the beginning of the year balances of valuation allowances increased income tax expense by $16 million in 2012 and decreased income tax expense by $7 million in 2011. None of the cumulative valuation allowances relate to amounts which if realized would increase contributed capital in the future. Approximately 73% of the Company’s net operating loss carryforwards expire from 2013 through 2032, and others are unlimited. The potential tax benefit from net operating loss carryforwards at the end of 2012 comprised state and local, and non-U.S. tax benefits of $78 million and $90 million, respectively, before reduction for valuation allowances. Foreign tax credit carryforwards expire from 2018 through 2022.

The realization of deferred tax assets depends on generating future taxable income in the applicable jurisdiction during the periods in which the tax benefits are deductible or creditable. The Company, including Marsh have been profitable globally. However, tax liabilities are determined and assessed on a legal entity and jurisdictional basis. Certain taxing jurisdictions allow or require combined or consolidated tax filings.

In the United States, certain groups within the Company, which file on a combined basis, were profitable in 2011 and 2012, but incurred a loss in 2010 as a result of the cost resulting from the resolution of the ARMB matter. The Company assessed the realizability of its domestic deferred tax assets, particularly state deferred tax assets of Marsh relating to jurisdictions in which it files separate tax returns, state deferred tax assets of all of the Company's domestic operations related to jurisdictions in which the Company files a unitary or combined state tax return, and foreign tax credit carryforwards in the Company's consolidated U.S. federal tax return. When making its assessment about the realization of its domestic deferred tax assets at December 31, 2012, the Company considered all available evidence, placing particular weight on evidence that could be objectively verified. The evidence considered included (i) the profitability of the Company's U.S. operations in 2011 and 2012 and the cumulative period from 2010 through 2012, (ii) the nature, frequency, and severity of financial reporting losses incurred prior to

68

2011, (iii) profit trends evidenced by continued improvements in the Company's and Marsh's operating performance, (iv) the non-recurring nature of some of the items that contributed to the losses before 2011, (v) the carryforward periods for the net operating losses ("NOLs") and foreign tax credit carryforwards, (vi) the sources and timing of future taxable income, giving weight to sources according to the extent to which they can be objectively verified, and (vii) tax planning strategies that would be implemented, if necessary, to accelerate utilization of NOLs. Based on its assessment, the Company concluded that it is more likely than not that a substantial portion of these deferred tax assets are realizable and a valuation allowance was recorded to reduce the domestic tax assets to the amount that the Company believes is more likely than not to be realized. In the event sufficient taxable income is not generated in future periods, additional valuation allowances of up to approximately $270 million could be required relating to these domestic deferred tax assets. The realization of the remaining U.S. federal deferred tax assets is not as sensitive to U.S. profits because it is supported by anticipated repatriation of future annual earnings from the Company’s profitable global operations, consistent with the Company's historical practice. In addition, when making its assessment about the realization of its domestic deferred tax assets at December 31, 2012, the Company continued to assess the realizability of deferred tax assets of certain other entities with a history of recent losses, including other U.S. entities that file separate state tax returns and foreign subsidiaries, and recorded valuation allowances as appropriate.

Following is a reconciliation of the Company’s total gross unrecognized tax benefits for the years ended December 31, 2012, 2011 and 2010:

(In millions of dollars)	2012			2011			2010
Balance at January 1,	$	143		$	199		$	206
Additions, based on tax positions related to current year	26			7			7
Additions for tax positions of prior years	35			39			10
Reductions for tax positions of prior years	(41		)	(91		)	(6		)
Reductions due to reclassification of tax indemnifications on sale of Kroll	—			—			(3		)
Settlements	(6		)	(6		)	(4		)
Lapses in statutes of limitation	(40		)	(5		)	(11		)
Balance at December 31,	$	117		$	143		$	199

Of the total unrecognized tax benefits at December 31, 2012, 2011 and 2010, $96 million, $102 million and $123 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, 2012 , 2011 and 2010, before any applicable federal benefit, was $13 million, $17 million and $35 million, respectively.

As discussed in Note 5, the Company has provided certain indemnities related to contingent tax liabilities as part of the disposals of Putnam and Kroll. At December 31, 2012, 2011 and 2010, $6 million, $14 million and $75 million, respectively, included in the table above, relates to Putnam and Kroll positions included in consolidated Company tax returns. Since the Company remains primarily liable to the taxing authorities for resolution of uncertain tax positions related to consolidated returns, these balances will remain as part of the Company’s consolidated liability for uncertain tax positions. Any future charges or credits that are directly related to the disposal of Putnam and Kroll and the indemnified contingent tax issues, including interest accrued, will be recorded in discontinued operations as incurred. The balance of gross unrecognized tax benefits at January 1, 2010 in the chart above includes balances related to stand alone tax filings of Kroll that were reclassified and are included as part of the fair value liability for contingent tax indemnities following the sale transaction.

The Company is routinely examined by the jurisdictions in which it has significant operations. The Internal Revenue Service (IRS) is currently examining 2009 and 2010.   During 2011, the Company was accepted to participate in the IRS Compliance Assurance Process (CAP) which is structured to conduct real-time compliance reviews.  The IRS is currently examining 2011 and performing a pre-filing review of the Company's 2012 U.S. operations. New York State has examinations underway for various entities covering the years 2007 through 2010. At the end of 2012, Massachusetts issued Notices of Assessment

69

for 2007 for various entities and the Company is currently appealing those assessments. During 2012, the United Kingdom completed its examination of tax year 2010 for various subsidiaries. There are no ongoing tax audits in the jurisdictions outside the U.S. in which the company has significant operations. The Company regularly considers the likelihood of assessments in each of the taxing jurisdictions resulting from examinations. The Company has established appropriate liabilities for uncertain tax positions in relation to the potential assessments. The Company believes the resolution of tax matters will not have a material effect on the consolidated financial position of the Company, although a resolution of tax matters could have a material impact on the Company's net income or cash flows and on its effective tax rate in a particular future period. It is reasonably possible that the total amount of unrecognized tax benefits will decrease between zero and approximately $25 million within the next twelve months due to settlement of audits and expiration of statutes of limitation.

8.    Retirement Benefits

The Company maintains qualified and non-qualified defined benefit pension plans for its U.S. and non-U.S. eligible employees. The Company’s policy for funding its tax qualified defined benefit retirement plans is to contribute amounts at least sufficient to meet the funding requirements set forth by U.S. law and the laws of the non-U.S. jurisdictions in which the Company offers defined benefit plans.

Combined U.S. and non-U.S. Plans

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

	Pension  Benefits				Postretirement Benefits
	2012		2011		2012		2011
Weighted average assumptions:
Discount rate (for expense)	4.91	%	5.59	%	5.05	%	5.81	%
Expected return on plan assets	8.03	%	8.19	%	—		—
Rate of compensation increase (for expense)	3.09	%	4.08	%	—		—
Discount rate (for benefit obligation)	4.38	%	4.91	%	4.32	%	5.05	%
Rate of compensation increase (for benefit obligation)	2.43	%	3.09	%	—		—

The Company uses actuaries from Mercer, a subsidiary of the Company, to perform valuations of its pension plans. The long-term rate of return 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. The Company generally does not adjust the rate of return assumption from year to year if, at the measurement date, it is within the best estimate range, defined as between the 25^thand 75^thpercentile of the expected long-term annual returns in accordance with the “American Academy of Actuaries Pension Practice Council Note May 2001 Selecting and Documenting Investment Return Assumptions” and consistent with Actuarial Standards of Practice No. 27. Historical long-term average asset returns of each plan are also reviewed to determine whether they are consistent and reasonable compared with the best estimate range. 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 recorded.

70

The target asset allocation for the U.S. Plan is 58% equities and equity alternatives and 42% fixed income. At the end of 2012, the actual allocation for the U.S. Plan was 58% equities and equity alternatives and 42% fixed income. The target asset allocation for the U.K. Plan, which comprises approximately 82% of non-U.S. Plan assets, is 53% equities and equity alternatives and 47% fixed income. At the end of 2012, the actual allocation for the U.K. Plan was 52% equities and equity alternatives and 48% 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 rebalancing to ensure the actual portfolio remains consistent with target asset allocation ranges.

The discount rate selected for each U.S. plan is based on a model bond portfolio with coupons and redemptions that closely match the expected liability cash flows from the plan. Discount rates for non-U.S. plans are based on appropriate bond indices such as the Markit iBoxx £ Corporates AA 15+ index in the U.K. Projected compensation increases reflect current expectations as to future levels of inflation.

The components of the net periodic benefit cost for defined benefit and other postretirement plans are as follows:

Combined U.S. and significant non-U.S. Plans	Pension									Postretirement
For the Years Ended December 31,	Benefits									Benefits
(In millions of dollars)	2012			2011			2010			2012			2011			2010

Net periodic benefit cost	$	182		$	144		$	83		$	4		$	1		$	5

Plan Assets

For the U.S. plan, 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, 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. qualified plan, the category ranges are 53-63% for equities and equity alternatives, and 37-47% for fixed income. For the U.K. Plan, the category ranges are 50-56% for equities and equity alternatives, and 44-50% for fixed income. Asset allocation ranges are evaluated generally every three years. 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.

71

Unrecognized Actuarial Gains/Losses

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

The weighted average actuarial assumptions utilized in determining the above amounts for the U.S. defined benefit and other U.S. postretirement plans as of the end of the year are as follows:

	U.S. Pension Benefits				U.S. Postretirement Benefits
	2012		2011		2012		2011
Weighted average assumptions:
Discount rate (for expense)	5.15	%	5.90	%	5.10	%	5.95	%

Rate of compensation increase (for benefit obligation)	2.00	%	2.00	%	—		—

The projected benefit obligation, accumulated benefit obligation and aggregate fair value of plan assets for U.S. pension plans with accumulated benefit obligations in excess of plan assets were $5.2 billion, $5.1 billion and $3.9 billion, respectively, as of December 31, 2012 and $4.5 billion, $4.5 billion and $3.5 billion, respectively, as of December 31, 2011.

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 $5.2 billion and $3.9 billion, respectively, as of December 31, 2012 and $4.5 billion and $3.5 billion, respectively, as of December 31, 2011.

As of December 31, 2012, the U.S. qualified plan holds eight million shares of the Company’s common stock which were contributed to the Plan by the Company in 2005. This represents approximately 7% of that plan’s assets as of December 31, 2012. In addition, plan assets may be invested in funds managed by Mercer Investments.

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

U.S. Plans only	Pension Benefits									Postretirement Benefits

In December 2003, the Medicare Prescription Drug, Improvement and Modernization Act of 2003 became law. The net periodic benefit cost shown above for 2012, 2011 and 2010, respectively, includes the subsidy.

The assumed health care cost trend rate for Medicare eligibles is approximately 7.86% in 2012, gradually declining to 4.5% in 2028, and the rate for non-Medicare eligibles is 7.73% in 2012, gradually declining to 4.50% in 2028. Assumed health care cost trend rates have a small effect on the amounts reported for the U.S. health care plans because the Company caps its share of health care trend at 5%. A one percentage point change in assumed health care cost trend rates would have the following effects:

Estimated Future Contributions

The Company expects to fund approximately $25 million for its U.S. non-qualified plan in 2013. The Company’s policy for funding its tax-qualified defined benefit retirement plans is to contribute amounts at

74

least sufficient to meet the funding requirements set forth in the U.S. and applicable foreign law. There currently is no ERISA funding requirement for the U.S. qualified plan for 2013.

The non-U.S. defined benefit plans do not have any direct ownership of the Company’s common stock.

The pension plan in the United Kingdom holds a limited partnership interest in the Trident III private equity fund valued at approximately $200 million at December 31, 2012.

The projected benefit obligation, accumulated benefit obligation and fair value of plan assets for the non-U.S. pension plans with accumulated benefit obligations in excess of plan assets were $1.7 billion, $1.6 billion and $1.2 billion, respectively, as of December 31, 2012 and $1.4 billion, $1.3 billion and $1 billion, respectively, as of December 31, 2011.

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, 2012 and $7.6 billion and $7.0 billion, respectively, as of December 31, 2011.

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

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

Estimated Future Contributions

The Company expects to fund approximately $623 million to its non-U.S. pension plans in 2013. 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.

Estimated Future Benefit Payments

The Plan’s estimated future benefit payments for its pension and postretirement benefits (without reduction for Medicare subsidy receipts) at December 31, 2012 are as follows:

December 31,	Pension Benefits				Postretirement Benefits
(In millions of dollars)	U.S.		Non-U.S.		U.S.		Non-U.S.

Defined Benefit Plans Fair Value Disclosures

In December 2008 the FASB issued guidance for Employers’ Disclosures About Pension and Other Post Retirement Benefit Plan Assets. The guidance requires fair value plan asset disclosures for an employer’s defined benefit pension and postretirement plans similar to the guidance on Fair Value Measurements as well as (a) how investment allocation decisions are made, (b) the major categories of plan assets, and (c) significant concentrations of risk within plan assets.

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; and Level 3, which refers to investments valued based on significant unobservable inputs. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

78

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, 2012 and 2011.

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 and rights/warrants (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 paper (included in corporate obligations):  The fair value of commercial paper is estimated using observable market data such as maturity date, issue date, credit rating, current commercial paper rates and settlement date.

Commercial mortgage-backed and asset-backed securities (included in corporate obligations):  Fair value is determined using discounted cash flow models. Observable inputs are based on trade and quote activity of bonds with similar features including issuer vintage, purpose of underlying loan (first or second lien), prepayment speeds and credit ratings. The discount rate is the combination of the appropriate rate from the benchmark yield curve and the discount margin based on quoted prices.

Common/Collective trusts:  Valued at the quoted market prices of the underlying investments at year end.

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

80

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. The managers provide unaudited quarterly financial statements and audited annual financial statements which set forth the value of the fund. The valuations obtained from the managers are based on various analyses on the underlying holdings in each partnership, including financial valuation models and projections, comparable valuations from the public markets, and precedent private market transactions. Investments are valued in the accompanying financial statements based on the Plan’s beneficial interest in the underlying net assets of the partnership as determined by the partnership agreement.

Insurance group annuity contracts:  The fair values for these investments are based on the current market value of the aggregate accumulated contributions plus interest earned.

Swap assets and liabilities:  Fair values for interest rate swaps, equity index swaps and inflation swaps are estimated using a discounted cash flow pricing model. These models use observable market data such as contractual fixed rate, broker quotes, spot equity price or index value and dividend data. The fair values of credit default swaps are estimated using an income approach model which determines expected cash flows based on default probabilities from the issuer specific credit spread curve and credit loss recovery rates, both of which are dependent on market quotes.

Real estate investment trusts:  Valued at the closing price reported on an exchange.

Short-term investment funds:  Primarily high-grade money market instruments valued at net asset value at year-end.

Real estate: Valued by investment managers generally using proprietary pricing models.

Registered investment companies:  Valued at the closing price reported on the primary exchange.

Defined Contribution Plans

The Company maintains certain defined contribution plans for its employees, including the Marsh & McLennan Companies 401(k) Savings & Investment Plan (“401(k) Plan”), that are qualified under U.S. tax laws. Under these plans, eligible employees may contribute a percentage of their base salary, subject to certain limitations. For the 401(k) Plan, the Company matches a fixed portion of the employees’ contributions. The 401(k) Plan contains an Employee Stock Ownership Plan feature under U.S. tax law. Approximately $375 million of the 401(k) Plan’s assets at December 31, 2012 and $366 million at December 31, 2011 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 related to continuing operations was $50 million in 2012 and $48 million for 2011 and 2010.

9. Stock Benefit Plans

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

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

On May 19, 2011, the Marsh & McLennan Companies, Inc. 2011 Incentive and Stock Award Plan (the “2011 Plan”) was approved by the Company's stockholders. The 2011 Plan replaced the Company's two previous equity incentive plans (the 2000 Senior Executive Incentive and Stock Award Plan and the 2000 Employee Incentive and Stock Award Plan).

81

The types of awards permitted under the 2011 Plan include stock options, restricted stock and restricted stock units payable in Company common stock or cash, and other stock-based and performance-based awards. The Compensation Committee of the Board of Directors (the “Compensation Committee”) determines, at its discretion, which affiliates may participate in the 2011 Plan, which eligible employees will receive awards, the types of awards to be received, and the terms and conditions thereof. The right of an employee to receive an award may be subject to performance conditions as specified by the Compensation Committee. The 2011 Plan contains provisions which, in the event of a change in control of the Company, may accelerate the vesting of the awards. The 2011 Plan retains the remaining share authority of the two previous plans as of the date the 2011 Plan was approved by stockholders. Awards relating to not more than approximately 23.2 million shares of common stock, plus shares remaining unused under certain pre-existing plans, may be made over the life of the 2011 Plan.

Our current practice is to grant non-qualified stock options, restricted stock units and/or performance stock units on an annual basis to senior executives and a limited number of other employees as part of their total compensation. We also grant restricted stock units during the year to new hires or as retention awards for certain employees. We have not granted restricted stock since 2005.

Stock Options: Options granted under the 2011 Plan may be designated as either incentive stock options or non-qualified stock options. The Compensation Committee determines the terms and conditions of the option, including the time or times at which an option may be exercised, the methods by which such exercise price may be paid, and the form of such payment. Options are generally granted with an exercise price equal to the market value of the Company's common stock on the date of grant. These option awards generally vest 25% per annum and have a contractual term of 10 years. Certain stock options granted under the previous equity incentive plans provided for a market-based triggering event before a vested option can be exercised. The terms and conditions of these stock option awards provided that (i) options will vest at a rate of 25% a year beginning one year from the date of grant and (ii) each vested tranche will only become exercisable if the market price of the Company stock appreciates to a level of 15% above the exercise price of the option and maintains that level for at least ten (10) consecutive trading days after the award has vested. The Company accounts for these awards as market-condition options. The effect of the market condition is reflected in the grant-date fair value of such awards. Compensation cost is recognized over the requisite service period and is not subsequently adjusted if the market condition is not met. For awards without a market-based triggering event, compensation cost is generally recognized on a straight-line basis over the requisite service period which is normally the vesting period.

The estimated fair value of options granted without a market-based triggering event is calculated using the Black-Scholes option pricing valuation model. This model takes into account several factors and assumptions. The risk-free interest rate is based on the yield on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumption at the time of grant. The expected life (estimated period of time outstanding) is estimated using the contractual term of the option and the effects of employees' expected exercise and post-vesting employment termination behavior. The Company uses a blended volatility rate based on the following: (i) volatility derived from daily closing price observations for the 10-year period ended on the valuation date, (ii) implied volatility derived from traded options for the period one week before the valuation date and (iii) average volatility for the 10-year periods ended on 15 anniversaries prior to the valuation date, using daily closing price observations. The expected dividend yield is based on expected dividends for the expected term of the stock options.

82

The assumptions used in the Black-Scholes option pricing valuation model for options granted by the Company in 2012, 2011 and 2010 are as follows:

	2012	2011	2010
Risk-free interest rate	1.26%-1.27%	2.28%-2.90%	3.15%-3.20%
Expected life (in years)	6.50	6.75	6.75
Expected volatility	26.2%-26.4%	25.4%-25.8%	26.3%-27.6%
Expected dividend yield	2.76%-2.80%	2.75%-2.86%	3.26%-3.52%

The estimated fair value of options granted with a market-based triggering event is calculated using a binomial valuation model. The factors and assumptions used in this model are similar to those utilized in the Black-Scholes option pricing valuation model except that the risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve over the contractual term of the option, and the expected life is calculated by the model. Since 2009, there have been no options granted with a market-based triggering event.

A summary of the status of the Company’s stock option awards as of December 31, 2012 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, 2012	38,895,109		$	29.21
Granted	3,547,733		$	31.88
Exercised	(6,892,731	)	$	26.01
Canceled or exchanged	—		—
Forfeited	(860,022	)	$	27.69
Expired	(2,644,296	)	$	42.85
Balance at December 31, 2012	32,045,793		$	29.10	4.5 years	186,467
Options vested or expected to vest at December 31, 2012	32,004,297		$	29.12	4.4 years	185,871
Options exercisable at December 31, 2012	16,115,605		$	28.85	3.8 years	106,606

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, 2012, 2011 and 2010 was $6.04, $6.67 and $4.85, respectively. The total intrinsic value of options exercised during the same periods was $57.7 million, $23.6 million and $0.5 million, respectively.

As of December 31, 2012, there was $18 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 1.3 years. Cash received from the exercise of stock options for the years ended December 31, 2012, 2011 and 2010 was $179.3 million, $111.7 million and $1.5 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 are available.

Restricted Stock Units and Performance Stock Units: Restricted stock units may be awarded under the Company's 2011 Incentive and Stock Award Plan. The Compensation Committee determines the restrictions on such units, when the restrictions lapse, when the units vest and are paid, and under what terms the units are forfeited. The cost of these awards is amortized over the vesting period, which is generally three years. Awards to senior executives and other employees may include three-year

83

performance-based restricted stock units and three-year service-based restricted stock units. The payout of performance-based restricted stock units (payable in shares of the Company's common stock) may range, generally, from 0-200% of the number of units granted, based on the achievement of objective, pre-determined Company or operating company performance measures, generally, over a three-year performance period. The Company accounts for these awards as performance condition restricted stock units. The performance condition is not considered in the determination of grant date fair value of such awards. Compensation cost is recognized over the performance period based on management's estimate of the number of units expected to vest and is adjusted to reflect the actual number of shares paid out at the end of the three-year performance period. Beginning with awards granted on or after February 23, 2009, dividend equivalents are not paid out unless and until such time that the award vests.

A summary of the status of the Company's restricted stock units and performance stock units as of December 31, 2012 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, 2012	15,058,428		$	25.43	368,346		$	30.60
Granted	2,797,287		$	31.96	461,756		$	31.89
Vested	(8,209,388	)	$	23.97	(25,129	)	$	30.83
Forfeited	(682,089	)	$	28.49	(81,075	)	$	31.31
Adjustment due to performance	—		$	—	6,940		$	30.60
Non-vested balance at December 31, 2012	8,964,238		$	28.58	730,838		$	31.32

The weighted-average grant-date fair value of the Company's restricted stock units and performance stock units granted during the year ended December 31, 2011 was $30.46 and $30.60, respectively; the combined weighted-average grant-date fair value of the Company's restricted stock units and performance stock units granted during the year ended December 31, 2010 was $22.81. The total fair value of the shares distributed during the years ended December 31, 2012, 2011 and 2010 in connection with the Company's restricted stock units and performance stock units was $262.6 million, $249 million and $170.7 million, respectively.

The number of vested performance stock units includes any applicable performance adjustment shares. The adjustment due to performance reflects the incremental portion of the above-target payout (160%) of performance stock units awarded in February 2011 that vested during 2012 either in full or on a pro-rata basis due to certain types of termination of employment. There is no adjustment due to performance for performance stock units awarded in February 2012 that vested during 2012 due to certain types of termination of employment within the calendar year of grant since the payout of such awards is at 100% of target under the award's terms and conditions.

Restricted Stock: Restricted shares of the Company's common stock may be awarded under the 2011 Plan and are subject to restrictions on transferability and other restrictions, if any, as the Compensation Committee may impose. The Compensation Committee may also determine when and under what circumstances the restrictions may lapse and whether the participant receives the rights of a stockholder, including, without limitation, the right to vote and receive dividends. Unless the Compensation Committee determines otherwise, restricted stock that is still subject to restrictions is forfeited upon termination of employment. Shares granted, generally become unrestricted at the earlier of: (1) January 1 of the year following the vesting grant date anniversary or (2) the later of the recipient's normal or actual retirement date. For shares granted prior to 2004, the vesting grant date anniversary is ten years. For shares granted during 2004 and 2005, the vesting grant date anniversary is 7 years and 5 years, respectively. However, certain restricted shares granted in 2005 vested on the third anniversary of the grant date. There have been no restricted shares granted since 2005.

84

A summary of the status of the Company's restricted stock awards as of December 31, 2012 and changes during the period then ended is presented below:

	Shares		Weighted Average Grant Date Fair Value
Non-vested balance at January 1, 2012	51,700		$	46.86
Granted	—		$	—
Vested	(20,000	)	$	46.14
Forfeited	—		$	—
Non-vested balance at December 31, 2012	31,700		$	47.31

The total fair value of the Company's restricted stock distributed was $0.6 million for each of the years ended December 31, 2012 and December 31, 2011. There were no restricted stock distributions in 2010.

As of December 31, 2012, there was $135 million of unrecognized compensation cost related to the Company's restricted stock, restricted stock units and performance stock unit awards. The weighted-average period over which that cost is expected to be recognized is approximately 1 year.

Marsh & McLennan Companies Stock Purchase Plans

In May 1999, the Company's stockholders approved an employee stock purchase plan (the “1999 Plan”) to replace the 1994 Employee Stock Purchase Plan (the “1994 Plan”), which terminated on September 30, 1999 following its fifth annual offering. Under the current terms of the Plan, shares are purchased four times during the plan year at a price that is 95% of the average market price on each quarterly purchase date. Under the 1999 Plan, after including the available remaining unused shares in the 1994 Plan and reducing the shares available by 10,000,000 consistent with the Company's Board of Directors' action in March 2007, no more than 35,600,000 shares of the Company's common stock may be sold. Employees purchased 899,424 shares during the year ended December 31, 2012 and at December 31, 2012, 4,136,312 shares were available for issuance under the 1999 Plan. Under the 1995 Company Stock Purchase Plan for International Employees (the “International Plan”), after reflecting the additional 5,000,000 shares of common stock for issuance approved by the Company's Board of Directors in July 2002, and the addition of 4,000,000 shares due to a shareholder action in May 2007, no more than 12,000,000 shares of the Company's common stock may be sold. Employees purchased 111,073 shares during the year ended December 31, 2012 and there were 3,085,961 shares available for issuance at December 31, 2012 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 in ASC Topic No. 820 (“Fair Value Measurements and Disclosures”). 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, most U.S. Government and agency securities, money market mutual funds and certain other sovereign government obligations).

85

Assets and liabilities utilizing Level 1 inputs include exchange traded equity securities and mutual 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 utilizing Level 2 inputs include corporate and municipal bonds, senior notes and interest rate swaps.

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 (examples include private equity investments, certain commercial mortgage whole loans, and long-dated or complex derivatives including certain foreign exchange options and long-dated options on gas and power).

Liabilities utilizing Level 3 inputs include liabilities for contingent purchase consideration.

Valuation Techniques

Equity Securities & Mutual Funds - Level 1

Investments for which market quotations are readily available are valued at the sale price on their principal exchange, or official closing bid price for certain markets. If no sales are reported, the security is valued at its last reported bid price.

Other Sovereign Government Obligations, Municipal Bonds and Corporate Bonds - Level 2

The investments listed in the caption above are valued on the basis of valuations furnished by an independent pricing service approved by the trustees or dealers. Such services or dealers determine valuations for normal institutional-size trading units of such securities using methods based on market transactions for comparable securities and various relationships, generally recognized by institutional traders, between securities.

Interest Rate Swap Derivative - Level 2

The fair value of interest rate swap derivatives is based on the present value of future cash flows at each valuation date resulting from utilization of the swaps, using a constant discount rate of 1.6% compared to discount rates based on projected future yield curves. (See Note 12)

Senior Notes due 2014 - Level 2

The fair value of the first $250 million of Senior Notes maturing in 2014 is estimated to be the carrying value of those notes adjusted by the fair value of the interest rate swap derivative, discussed above. In the first quarter of 2011, the Company entered into two interest rate swaps to convert interest on a portion of its Senior Notes from a fixed rate to a floating rate. The swaps are designated as fair value hedging instruments. The change in the fair value of the swaps is recorded on the balance sheet. The carrying value of the debt related to these swaps is adjusted by an equal amount. (See Note 12).

86

Contingent Purchase Consideration Liability - Level 3

Purchase consideration for some acquisitions made by the Company includes contingent consideration arrangements. Contingent consideration arrangements are primarily based on meeting EBITDA and revenue targets over periods from two to four years. The fair value of contingent consideration is estimated as the present value of future cash flows that would result from the projected revenue and earnings of the acquired 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, 2012 and 2011.

(In millions of dollars)	Identical Assets (Level 1)				Observable Inputs (Level 2)				Unobservable Inputs (Level 3)				Total

(a) Included in other assets in the consolidated balance sheets.

(b) Included in cash and cash equivalents in the consolidated balance sheets.

(c) Included in other receivables in the consolidated balance sheets.

(d) Included in accounts payable and accrued liabilities and other liabilities in the consolidated balance sheets.

(e) Included in long term debt in the consolidated balance sheets.

During the year ended December 31, 2012, there were no assets or liabilities that transferred between Level 1 and Level 2 or between Level 2 and Level 3.

The table below sets forth a summary of the changes in fair value of the Company’s Level 3 liabilities for the years ended December 31, 2012 and December 31, 2011 that represent contingent purchase consideration related to acquisitions:

(In millions of dollars)	2012			2011
Balance at January 1,	$	110		$	106
Additions	27			14
Payments	(30		)	(13		)
Revaluation Impact	(44		)	3
Balance at December 31,	$	63		$	110

87

The fair value of the contingent purchase consideration liability is based on projections of revenue and earnings for the acquired entities that are reassessed on a quarterly basis. As set forth in the table above, based on the Company's ongoing assessment of the fair value of contingent purchase consideration liability, the Company recorded a net reduction in the estimated fair value of such liabilities for acquisitions made in prior periods of $44 million for the year ended December 31, 2012. A 5% increase in the above mentioned projections would increase the liability by approximately $30 million. A 5% decrease in the above mentioned projections would decrease the liability by approximately $20 million.

Fair Value of Long-term Investments

The Company has certain long-term investments, primarily related to investments in non-publicly traded private equity funds of $16 million and $38 million at December 31, 2012 and December 31, 2011, respectively, carried on the cost basis for which there are no readily available market prices. The carrying values of these investments approximates fair value. Management's estimate of the fair value of these non-publicly traded investments is based on valuation methodologies including estimates from private equity managers of the fair value of underlying investments in private equity funds. The ability to accurately predict future cash flows, revenue or earnings may impact the determination of fair value. The Company monitors these investments for impairment and makes appropriate reductions in carrying values when necessary. These investments would be classified as Level 3 in the fair value hierarchy and are included in Other assets in the consolidated balance sheets. The Company also has investments in publicly traded mutual funds of $19 million and $20 million at December 31, 2012 and December 31, 2011, related to voluntary deferred contribution plans. These investments are classified as Level 1 in the fair value hierarchy and are included in Other assets in the consolidated balance sheets.

11.    Long-term Commitments

The Company leases office facilities, equipment and automobiles under non-cancelable operating leases. These leases expire on varying dates; in some instances contain renewal and expansion options; do not restrict the payment of dividends or the incurrence of debt or additional lease obligations; and contain no significant purchase options. In addition to the base rental costs, occupancy lease agreements generally provide for rent escalations resulting from increased assessments for real estate taxes and other charges. Approximately 98% of the Company’s lease obligations are for the use of office space.

The consolidated statements of income include net rental costs of $416 million, $430 million and $421 million for 2012, 2011 and 2010, respectively, after deducting rentals from subleases ($10 million in 2012, $9 million in 2011 and $8 million in 2010). These net rental costs exclude rental costs and sublease income for previously accrued restructuring charges related to vacated space.

At December 31, 2012, the aggregate future minimum rental commitments under all non-cancelable operating lease agreements are as follows:

For the Years Ended December 31,	Gross Rental Commitments		Rentals from Subleases		Net Rental Commitments
(In millions of dollars)
2013	$	404	$	49	$	355
2014	$	359	$	48	$	311
2015	$	315	$	43	$	272
2016	$	279	$	42	$	237
2017	$	236	$	40	$	196
Subsequent years	$	1,227	$	109	$	1,118

The Company has entered into agreements, primarily with various service companies, to outsource certain information systems activities and responsibilities and processing activities. Under these agreements, the Company is required to pay minimum annual service charges. Additional fees may be payable depending upon the volume of transactions processed, with all future payments subject to increases for inflation. At December 31, 2012, the aggregate fixed future minimum commitments under these agreements are as follows:

88

For the Years Ended December 31,	Future Minimum Commitments
(In millions of dollars)
2013	$	168
2014	87
2015	48
Subsequent years	118
	$	421

12.    Debt

Other	1		1
	2,918		2,928
Less current portion	260		260
	$	2,658	$	2,668

The senior notes in the table above are publically registered by the Company with no guarantees attached.

During the first quarter of 2012, the Company repaid its 6.25% fixed rate $250 million senior notes that matured. The Company used proceeds from the issuance of 2.3%five-year $250 million senior notes in the first quarter of 2012 to fund the maturing notes.

On July 15, 2011, the Company purchased a total of $600 million of outstanding notes comprised of $330 million of its 5.375% notes due in 2014 and $270 million of its 5.750% notes due in 2015. The Company acquired the notes at market value plus a tender premium, which exceeded the notes' carrying values.

The Company used proceeds from the issuance of 4.80%ten-year $500 million senior notes in the third quarter of 2011 and cash on hand to fund the amounts associated with the tendered bonds.

In February 2013, the Company repaid $250 million of maturing senior notes.

The Company and certain of its foreign subsidiaries maintain a $1.0 billion multi-currency five-year unsecured revolving credit facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. This facility requires the Company to maintain certain

89

coverage and leverage ratios which are measured quarterly. There were no borrowings outstanding under this facility at December 31, 2012.

In December 2012, the Company closed on a $50 million, three-year delayed draw term loan facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. The Company has the ability to increase the loan amount by $100 million during the life of the loan. The facility requires the Company to maintain coverage ratios and leverage ratios consistent with the revolving credit facility discussed above. There were no borrowings under this facility at December 31, 2012.

Derivative Financial Instruments

In February 2011, the Company entered into two$125 million3.5-year interest rate swaps to hedge changes in the fair value of the first $250 million of the outstanding 5.375% senior notes due in 2014.

Under the terms of the swaps, the counter-parties will pay the Company a fixed rate of 5.375% and the Company will pay interest at a floating rate of three-month LIBOR plus a fixed spread of 3.726%. The maturity date of the senior notes and the swaps match exactly. The floating rate resets quarterly, with every second reset occurring on the interest payment date of the senior notes. The swaps net settle every six months on the senior note coupon payment dates. The swaps are designated as fair value hedging instruments and are deemed to be perfectly effective in accordance with applicable accounting guidance. The fair value of the swaps at inception was zero and subsequent changes in the fair value of the interest rate swaps are reflected in the carrying value of the interest rate swaps and in the consolidated balance sheet. The carrying value of the debt on the balance sheet was adjusted by an equal amount. The gain or loss on the hedged item (fixed rate debt) and the offsetting gain or (loss) on the interest rate swaps for the periods ended December 31, 2012 and December 31, 2011 is as follows:

	2012							2011
Income statement classification (In millions of dollars)	Loss on Swaps			Gain on Notes		Net Income Effect		Gain on Swaps		Loss on Notes			Net Income Effect
Other Operating Expenses	$	(1	)	$	1	$	—	$	7	$	(7	)	$	—

The amounts earned and owed under the swap agreements are accrued each period and are reported in interest expense. There was no ineffectiveness recognized in the periods presented. The portion of the debt acquired under the tender offer discussed above was not part of the first $250 million outstanding and therefore, did not impact the hedged portion of this debt.

Additional credit facilities, guarantees and letters of credit are maintained with various banks, primarily related to operations located outside the United States, aggregating $247 million at December 31, 2012 and $248 million at December 31, 2011. There were no outstanding borrowings under these facilities at December 31, 2012 or December 31, 2011.

Scheduled repayments of long-term debt in 2013 and in the four succeeding years are $260 million, $330 million, $491 million, $11 million and $262 million, respectively.

Fair value of Short-term and Long-term Debt

The estimated fair value of the Company’s short-term and long-term debt is provided below. Certain estimates and judgments were required to develop the fair value amounts. The fair value amounts shown below are not necessarily indicative of the amounts that the Company would realize upon disposition, nor do they indicate the Company’s intent or need to dispose of the financial instrument.

90

	December 31, 2012				December 31, 2011
(In millions of dollars)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Short-term debt	$	260	$	261	$	260	$	261
Long-term debt	$	2,658	$	2,986	$	2,668	$	2,958

The fair value of the Company’s short-term debt, which consists primarily of term debt maturing within the next year, 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.

13.    Integration and Restructuring Costs

In 2012, the Company implemented restructuring actions which resulted in costs totaling $78 million million. Approximately $58 million of the restructuring charges are related to Mercer, approximately $51 million of which was incurred in the fourth quarter of 2012 related to senior management's recent operations review, including costs of approximately $16 million related to the disposal of Mercer's Canadian outsourcing business. The remaining restructuring costs consist primarily of severance and benefits, costs for future rent and other real estate costs. These costs were incurred as follows: Risk and Insurance Services—$8 million (all acquisition related); Consulting—$58 million (acquisition related—$1 million); and Corporate—$12 million.

Details of the restructuring liability activity from January 1, 2011 through December 31, 2012, including actions taken prior to 2012 are as follows:

(In millions of dollars)	Balance at 1/1/11		Expense Incurred		Cash Paid			Other			Balance at 12/31/11		Expense Incurred		Cash Paid			Other			Balance at 12/31/12
Severance	$	40	$	29	$	(40	)	$	(2	)	$	27	$	46	$	(38	)	$	1		$	36
Future rent under non-cancelable leases and other costs	171		22		(42		)	3			154		32		(50		)	(2		)	134
Total	$	211	$	51	$	(82	)	$	1		$	181	$	78	$	(88	)	$	(1	)	$	170

As of January 1, 2010, the liability balance related to restructuring activity was $259 million. In 2010, the Company accrued $141 million and had cash payments of $189 million related to restructuring activities that resulted in the liability balance at January 1, 2011 reported above.

The expenses associated with the above initiatives are included in compensation and benefits and other operating expenses in the consolidated statements of income. The liabilities associated with these initiatives are classified on the consolidated balance sheets as accounts payable, other liabilities, or accrued compensation and employee benefits, depending on the nature of the items.

14.    Common Stock

During 2012, the Company repurchased 6.9 million shares of its common stock for total consideration of $230 million. The Company remains authorized to purchase additional shares of its common stock up to a value of $323 million. During 2011, the Company purchased 12.3 million shares of its common stock for total consideration of $361 million.

15.    Claims, Lawsuits and Other Contingencies

91

Errors and Omissions Claims

The Company and its subsidiaries, particularly Marsh and Mercer, are subject to a significant number of claims, lawsuits and proceedings in the ordinary course of business. Such claims and lawsuits consist principally of alleged errors and omissions in connection with the performance of professional services, including the placement of insurance, the provision of actuarial services for corporate and public sector clients, and the provision of consulting services relating to the drafting and interpretation of trust deeds and other documentation governing pension plans. Certain of these claims, particularly in the U.S. and the U.K., seek damages, including punitive and treble damages, in amounts that could, if awarded, be significant. In establishing liabilities for errors and omissions claims in accordance with FASB ASC Subtopic No.450-20 (Contingencies-Loss Contingencies), the Company utilizes case level reviews by inside and outside counsel and an internal actuarial analysis to estimate potential losses. A liability is established when a loss is both probable and reasonably estimable. The liability is reviewed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable.

To the extent that expected losses exceed our deductible in any policy year, the Company also records an asset for the amount that we expect to recover under any available third-party insurance programs. The Company has varying levels of third-party insurance coverage, with policy limits and coverage terms varying significantly by policy year.

Governmental Inquiries and Related Claims

In January 2005, the Company and its subsidiary Marsh Inc. entered into a settlement agreement with the New York State Attorney General (“NYAG”) and the New York State Insurance Department to settle a civil complaint and related citation regarding Marsh's use of market service agreements with various insurance companies. The parties subsequently entered into an amended and restated settlement agreement in February 2010 that restored a level playing field for Marsh.

Numerous private party lawsuits based on similar allegations to those made in the NYAG complaint were commenced against the Company, one or more of its subsidiaries, and their current and former directors and officers. Most of these matters have been resolved. Four actions instituted by policyholders against the Company, Marsh and certain Marsh subsidiaries remain pending in federal court.

Our activities are regulated under the laws of the United States and its various states, the European Union and its member states, and the other jurisdictions in which we operate. In the ordinary course of business we are also subject to investigations, lawsuits and/or other regulatory actions undertaken by governmental authorities.

Other Contingencies-Guarantees

In connection with its acquisition of U.K.-based Sedgwick Group in 1998, the Company acquired several insurance underwriting businesses that were already in run-off, including River Thames Insurance Company Limited (“River Thames”), which we 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 reinsured up to £40 million by a related party of River Thames. Payment of claims under the reinsurance agreement is collateralized by segregated assets held in a trust. As of December 31, 2012, the reinsurance coverage exceeded the best estimate of the projected liability of the policies covered by the guarantee. To the extent River Thames or the reinsurer is unable to meet its obligations under those policies, a claimant may seek to recover from us 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 July3, 1980 and October6, 1983. Certain claims have been paid under the letter of credit and we anticipate that additional claimants may seek to recover against the letter of credit.

Kroll-related Matters

Under the terms of a stock purchase agreement with Altegrity, Inc. (“Altegrity”) related to Altegrity's purchase of Kroll from the Company in August 2010, a copy of which is attached as an exhibit to the Company's Quarterly Report on Form 10-Q for the period ended June30, 2010, we agreed to provide a limited indemnity to Altegrity with respect to certain Kroll-related litigation and regulatory matters.

**********

The pending proceedings and other matters described in this Note 15 on Claims, Lawsuits and Other Contingencies may expose the Company or its subsidiaries to liability for significant monetary damages and other forms of relief. Where a loss is both probable and reasonably estimable, we establish liabilities in accordance with FASB ASC Subtopic No.450-20 (Contingencies-Loss Contingencies). Except as described above, we are 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.

New York, New York

We have audited the accompanying consolidated balance sheets of Marsh & McLennan Companies, Inc. and subsidiaries (the “Company”) as of December 31, 2012 and 2011, and the related consolidated statements of income, comprehensive income, cash flows and equity for each of the three years in the period ended December 31, 2012.  These financial statements are the responsibility of the Company's management.  Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Marsh & McLennan Companies, Inc. and subsidiaries as of December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012, 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), the Company's internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2013 expressed an unqualified opinion on the Company's 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, 2012 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. Based on its evaluation, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2012.

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, 2012.

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Marsh & McLennan Companies, Inc.

New York, New York

We have audited the internal control over financial reporting of Marsh & McLennan Companies, Inc. and subsidiaries (the “Company”) as of December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.  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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  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.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis.  Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2012 of the Company and our report dated February 27, 2013 expressed an unqualified opinion on those financial statements.

Marsh & McLennan Companies, Inc.

2000 Senior Executive Incentive and Stock Award Plan

Terms and Conditions for 2005 Award of Nonqualified Stock Options to U.S. Grant Recipients

This award of one or more nonqualified stock options (the “Grant”) has been granted to you on July 1, 2005 (the “Grant Date”) under the Marsh & McLennan Companies, Inc. (“MMC ”) 2000 Senior Executive Incentive and Stock Award Plan (the “Plan”) pursuant to your election to participate in MMC’s Offer to Exchange Outstanding Options, dated May 23, 2005, as amended. The Grant represents one or more options to purchase shares of MMC common stock and is sub- ject to the following terms and conditions:

I.GRANT

A. Grant Letter

The Grant Letter delivered to you sets forth the number of options under the Grant, the number of shares covered by each option, and the exercise price, vesting date(s) and expiration date of each option under the Grant.

B. Vesting and Exercisability of Option

Subject to your continued employment, the Grant will vest and become exercisable on the vesting date(s) set forth in your Grant Letter. Subject to the provisions of Section V herein, in the event of your termination of employment by reason of death, permanent disability or retirement, any unvested portion of the Grant will vest at such termination of employment and be exercisable as set forth in Section V. For all other terminations of employment, the Grant, whether vested or unvested, will be forfeited as of the date of your termination of employment.

II.METHOD OF EXERCISE

A. General Procedures.

An option may be exercised by written notice to MMC or an agent appointed by MMC, in form and substance satisfactory to MMC, which must state the election to exercise such option, the number of shares of stock for which such option is being exercised and such other representations and agreements as may be required pursuant to the provisions of these terms and conditions and the Plan. The written notice must be accompanied by (i) full payment of the aggregate exercise price for the number of shares of stock being purchased and (ii) an executed Non-Solicitation Agreement, unless you are exercising an option after you have retired on or after your Normal Retirement Date. An option exercise will be effective on the date on which written notice to exercise an option, full payment of the aggregate exercise price and an executed Non-Solicitation Agreement are received or, if received on different days, the latest of those dates.

B. Payment of Exercise Price.

Payment of the aggregate exercise price may be made with U.S. dollars or by tendering shares of MMC common stock (including shares acquired from the Stock Purchase Plan, a stock option exercise or a stock award vesting) which you have owned for at least six months prior to the exercise date having a value equal to or greater than the aggregate exercise price.

C. Non-Solicitation Agreement

You must execute and deliver a Non-Solicitation Agreement in connection with your option exercise unless you are exercising an option after you have retired on or after your Normal Retirement Date. If you retire on or after your Early Retirement Date and before your Normal Retirement Date, the Grant will be forfeited as of your termination of employment unless you sign the Non-Solicitation Agreement for Early Retirees within 30 days following your termination of employment (as described in Section V). You may obtain a copy of the Agreement from MMC or an agent appointed by MMC. You may wish to consider consulting an attorney before signing the Agreement. Please retain a copy of your signed Agreement for your records.

III. WITHHOLDING

Applicable taxes (including FICA) are required by law to be withheld when a nonqualified stock option is exercised. Unless you elect in your written notice to exercise an option to satisfy all applicable tax withholding by check, MMC will retain sufficient proceeds from an option exercise to satisfy the tax withholding obligation.

IV. REGISTRATION AND DISTRIBUTION OF SHARES

A. The shares from your stock option exercise will be registered as specified in your written notice to exercise an option, as of the date of exercise. The shares may be

registered only in (i) your name or (ii) your name and your spouse’s name as joint tenants with rights of survivorship.

B. The shares from your stock option exercise will be distributed as specified in your written notice to exercise an option, after you have satisfied your tax withholding obligation.

C. You will receive written confirmation of your stock option exercise by mail, generally wit hin a week following the exercise date.

V.TERMINATION OF EMPLOYMENT

If your employment with MMC or any of its subsidiaries or affiliates (the “Company”) terminates, the following shall apply:

A. Death

l.        While Employed

In the event your employment is terminated because of your death, any unvested portion of the Grant will vest and become exercisable at such termination of employment. The person or persons to whom your rights under the Grant shall pass by will or the laws of descent and distribution shall be entitled to exercise such option shares (and any option shares that were vested at the time of your death) within one year after the date of death, but in no event shall any option be exercised beyond the expiration date of such option.

2.Following Termination of Employment

In the event of your death following your termination of employment, any option that was vested at the time of your death will be exercisable by the person or persons to whom your rights under the Grant shall pass by will or the laws of descent and distribution. Such option may be exercised within one year after the date of death, but in no event beyond the expiration date of such option.

B.    Permanent Disability

In the event your employment is terminated due to total and permanent disability as determined under MMC’s long-term disability program, any unvested portion of the Grant will vest and become exercisable on the later of the second anniversary of the Grant Date or your termination of employment. Such vested option shares (and any option shares that were vested at the time of your termination of employment) sha ll be exercisable until the expiration date of the option.

C.    Retirement

In the event you retire on or after your Normal Retirement Date, any unvested portion of the Grant will vest and become exercisable on the later of the second anniversary of the Grant Date or your termination of employment. Such vested option shares (and any option shares that were vested at the time of your termination of employment) sha ll be exercisable until the expiration date of the option.

D.    Early Retirement

If (i) you retire on or after your Early Retirement Date and before your Normal Retirement Date and (ii) within 30 days following your termination of employment, you execute and comply with the Non-Solicitation Agreement for Early Retirees, then any unvested portion of the Grant will vest and become exercisable on the later of the second anniversary of the Grant Date or your termination of employment. Such vested option shares (and any option shares that were vested at the time of your termination of employment) sha ll be exercisable until the earlier of the fifth anniversary of your termination of employment and the expiration date of the option. The Non-Solicitation Agreement generally applies for a period of three years commencing with your termination of employment, or such lesser period as may be applicable. Failure to timely execute and comply with the Non-Solicitation Agreement will result in forfeit ure of your Grant, whether vested or unvested.

E.    Definitions

As used in Section V.C. and D., the terms “Normal Retirement Date” and “Early Retirement Date” shall have the respective meanings given such terms (or any comparable substitute terms or concepts) set forth in the Company’s primary retirement plan applicable to you upon your termination of employment.

F.    All Other Employment Terminations

For all other terminations of employment, the Grant, whether vested or unvested, shall be forfeited on the date of termination, except to the extent that the Compensation Committee of the MMC Board of Directors (the “Committee”) may determine otherwise.

VI. CHANGE IN CONTROL PROVISIONS

A. Change in Control

Upon the occurrence of a “Change in Control” of MMC, as defined in the Plan, options under the Grant will become fully vested and exercisable, and any restrictions contained in the terms and conditions of an option shall lapse.

B. Additional Payment

The value of the accelerated vesting of options because of a Change in Control (the “Ac- celerated Award”) may be subject to a 20% federal excise tax under Section 4999 of the Code (the “Excise Tax ”). The Excise Tax is imposed when the value, as determined by applicable regulations, of payments in the nature of compensation contingent on a Change in Control (including the Accelerated Award) equals or exceeds three times the average of your last five years’ W-2 earnings.

If a Change in Control occurs and vesting of options under the Grant is accelerated, MMC will determine if the Excise Tax is payable by you. If the Excise Tax is payable by you, MMC will pay to you, within five days of making the determination, an amount of money (the “Additional Payment ”) such that after payment of applicable federal, state and local income taxes, employment taxes and any Excise Tax imposed upon the Additional Payment, you will retain an amount of the Additional Payment equal to the Excise Tax imposed in respect of the Accelerated Award. If the Additional Payment, after payment of applicable taxes, is later determined to be less than the amount necessary to reimburse you for the Excise Tax you owe, a fur ther payment will be made to you. If the Additional Pay- ment, after payment of applicable taxes, is later determined to be more than the amount necessary to reimburse you for the Excise Tax you owe, you will be required to reimburse MMC for such excess.

VII. OTHER PROVISIONS

A. Neither the granting of the Grant nor any exercise thereof gives you any right to continue to be employed by the Company, or restricts, in any way, your right or the right of your employer to terminate your employment at any time for any reason not specifically prohibited by law.

B. During your lifetime, an option shall be exercisable only by you, and no right thereunder shall be transferable except by will or the laws of descent and distribution.

C. Neither you nor any person entitled to exercise your rights in the event of your death shall have any of the rights of a stockholder with respect to the shares of MMC common stock subject to an option, unless, and until, you have exercised the option, paid the full exercise price thereof, and have received the shares so acquired.

D. MMC is not liable for the non- issuance or non-transfer, nor for any delay in the issuance or transfer, of any shares of MMC common stock subject to an option or otherwise pursuant to the Plan which results from the inability of MMC to obtain, or in any delay in obtaining, from each regulatory body having jurisdiction, all requisite authority to issue or transfer shares of MMC common stock, if counsel for MMC deems such authority necessary for the lawful issuance or transfer of any such shares.

E. The Grant is subject to all of these terms and conditions and to the terms and conditions of the Plan, and your acceptance of the Grant shall constitute your agreement to the

terms and conditions of the Plan and the administrative regulations of the Committee. In the event of any inconsistency between these terms and conditions and the provisions of the Plan, the provisions of the Plan shall prevail. Your acceptance of the Grant constitutes your agreement that the shares of MMC common stock acquired hereunder will not be sold or otherwise disposed of by you in violation of any applicable securities laws or regulations.

F. An option shall be exercised in accordance with, and the Grant shall be subject to, such additional administrative regulations as the Committee may from time to time adopt. All decisions of the Committee upon any questions arising under the Plan or under these terms and conditions shall be conclusive and binding.

G. The Plan, and the granting and exercising of options or awards thereunder, and the obligations of MMC and employees under the Plan, shall be subject to all applicable governmental laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may be required, including, but not limited to, tax and securities regulations. This provision takes precedence over all aforementioned terms and conditions.

H. The Committee has full discretion and authority to control and manage the operation and administration of the Grant and the Plan. The Committee is comprised of at least two members of the MMC Board of Directors (the “Board of Directors”).

I. The Board of Directors may amend, alter, suspend, discontinue or terminate the Plan or the Committee’s authority to grant awards under the Plan, except that, without the consent of an affected participant, no such action may materially adversely affect the rights of such participant under any award theretofore granted to him or her. Following the occurrence of a Change in Control (as defined in the Plan), the Board of Directors may not terminate the Plan or amend the Plan with respect to awards that have already been granted in any manner adverse to employees.

J. No more than eight million (8,000,000) shares of MMC common stock (par value $1.00 per share), plus such number of shares remaining unused under pre-existing stock plans approved by MMC’s stockholders, may be issued under the Plan. Employees of the Company will be eligible for awards under the Plan. MMC common stock is traded on the New York Stock Exchange under the symbol “MMC” and is subject to market price fluctuation. The shares delivered upon exercise of an option may be obtained through open market purchases, treasury stock or newly issued shares.

K. The Plan is not qualified under Section 401(a) of the Internal Revenue Code and is not subject to the provisions of the Employee Retirement Income Security Act of 1974. Your right to payment of your Grant is the same as the right of an unsecured general creditor of MMC.

L. There are no investment fees associated with your Grant, and MMC pays all administrative expenses associated with your Grant.

This award of one or more nonqualified stock options (the “Grant”) has been granted to you on July 1, 2005 (the “Grant Date”) under the Marsh & McLennan Companies, Inc. (“MMC ”) 2000 Employee Incentive and Stock Award Plan (the “Plan”) pursuant to your election to participate in MMC’s Offer to Exchange Outstanding Options, dated May 23, 2005, as amended. The Grant represents one or more options to purchase shares of MMC common stock and is subject to the fol- lowing terms and conditions:

A. Grant Letter

The Grant Letter delivered to you sets forth the number of options under the Grant, the number of shares covered by each option, and the exercise price, vesting date(s) and expiration date of each option under the Grant.

B. Vesting and Exercisability of Option

Subject to your continued employment, the Grant will vest and become exercisable on the vesting date(s) set forth in your Grant Letter. Subject to the provisions of Section V herein, in the event of your termination of employment by reason of death, permanent disability or retirement, any unvested portion of the Grant will vest at such termination of employment and be exercisable as set forth in Section V. For all other terminations of employment, the Grant, whether vested or unvested, will be forfeited as of the date of your termination of employment.

II.METHOD OF EXERCISE

A. General Procedures.

An option may be exercised by written notice to MMC or an agent appointed by MMC, in form and substance satisfactory to MMC, which must state the election to exercise such option, the number of shares of stock for which such option is being exercised and such other representations and agreements as may be required pursuant to the provisions of these terms and conditions and the Plan. The written notice must be accompanied by (i) full payment of the aggregate exercise price for the number of shares of stock being purchased and (ii) an executed Non-Solicitation Agreement, unless you are exercising an option after you have retired on or after your Normal Retirement Date. An option exercise will be effective on the date on which written notice to exercise an option, full payment of the aggregate exercise price and an executed Non-Solicitation Agreement are received or, if received on different days, the latest of those dates.

B. Payment of Exercise Price.

Payment of the aggregate exercise price may be made with U.S. dollars or by tendering shares of MMC common stock (including shares acquired from the Stock Purchase Plan, a stock option exercise or a stock award vesting) which you have owned for at least six months prior to the exercise date having a value equal to or greater than the aggregate exercise price.

C. Non-Solicitation Agreement

You must execute and deliver a Non-Solicitation Agreement in connection with your option exercise unless you are exercising an option after you have retired on or after your Normal Retirement Date. If you retire on or after your Early Retirement Date and before your Normal Retirement Date, the Grant will be forfeited as of your termination of employment unless you sign the Non-Solicitation Agreement for Early Retirees within 30 days following your termination of employment (as described in Section V). You may obtain a copy of the Agreement from MMC or an agent appointed by MMC. You may wish to consider consulting an attorney before signing the Agreement. Please retain a copy of your signed Agreement for your records.

III. WITHHOLDING

Applicable taxes (including FICA) are required by law to be withheld when a nonqualified stock option is exercised. Unless you elect in your written notice to exercise an option to satisfy all applicable tax withholding by check, MMC will retain sufficient proceeds from an option exercise to satisfy the tax withholding obligation.

IV. REGISTRATION AND DISTRIBUTION OF SHARES

A. The shares from your stock option exercise will be registered as specified in your written notice to exercise an option, as of the date of exercise. The shares may be

registered only in (i) your name or (ii) your name and your spouse’s name as joint tenants with rights of survivorship.

B. The shares from your stock option exercise will be distributed as specified in your written notice to exercise an option, after you have satisfied your tax withholding obligation.

V.TERMINATION OF EMPLOYMENT

A. Death

l. While Employed

In the event your employment is terminated because of your death, any unvested portion of the Grant will vest and become exercisable at such termination of employment. The person or persons to whom your rights under the Grant shall pass by will or the laws of descent and distribution shall be entitled to exercise such option shares (and any option shares that were vested at the time of your death) within one year after the date of death, but in no event shall any option be exercised beyond the expiration date of such option.

2. Following Termination of Employment

In the event of your death following your termination of employment, any option that was vested at the time of your death will be exercisable by the person or persons to whom your rights under the Grant shall pass by will or the laws of descent and distribution. Such option may be exercised within one year after the date of death, but in no event beyond the expiration date of such option.

B. Permanent Disability

In the event your employment is terminated due to total and permanent disability as determined under MMC’s long-term disability program, any unvested portion of the Grant will vest and become exercisable on the later of the second anniversary of the Grant Date or your termination of employment. Such vested option shares (and any option shares that were vested at the time of your termination of employment) sha ll be exercisable until the expiration date of the option.

C. Retirement

In the event you retire on or after your Normal Retirement Date, any unvested portion of the Grant will vest and become exercisable on the later of the second anniversary of the Grant Date or your termination of employment. Such vested option shares (and any option shares that were vested at the time of your termination of employment) shall be exercisable until the expiration date of the option.

D. Early Retirement

If (i) you retire on or after your Early Retirement Date and before your Normal Retirement Date and (ii) within 30 days following your termination of employment, you execute and comply with the Non-Solicitation Agreement for Early Retirees, then any unvested portion of the Grant will vest and become exercisable on the later of the second anniversary of the Grant Date or your termination of employment. Such vested option shares (and any option shares that were vested at the time of your termination of employment) sha ll be exercisable until the earlier of the fifth anniversary of your termination of employment and the expiration date of the option. The Non-Solicitation Agreement generally applies for a period of three years commencing with your termination of employment, or such lesser period as may be applicable. Failure to timely execute and comply with the Non-Solicitation Agreement will result in forfeiture of your Grant, whether vested or unvested.

E. Definitions

As used in Section V.C. and D., the terms “Normal Retirement Date” and “Early Retirement Date” shall have the respective meanings given such terms (or any comparable substitute terms or concepts) set forth in the Company’s primary retirement plan applicable to you upon your termination of employment.

F. All Other Employment Terminations

For all other terminations of employment, the Grant, whether vested or unvested, shall be forfeited on the date of termination, except to the extent that the Compensation Committee of the MMC Board of Directors (the “Committee”) may determine otherwise.

VI. CHANGE IN CONTROL PROVISIONS

A. Change in Control

Upon the occurrence of a “Change in Control” of MMC, as defined in the Plan, options under the Grant will become fully vested and exercisable, and any restrictions contained in the terms and conditions of an option shall lapse.

B. Additional Payment

The value of the accelerated vesting of options because of a Change in Control (the “Ac- celerated Award”) may be subject to a 20% federal excise tax under Section 4999 of the Code (the “Excise Tax ”). The Excise Tax is imposed when the value, as determined by applicable regulations, of payments in the nature of compensation contingent on a Change in Control (including the Accelerated Award) equals or exceeds three times the average of your last five years’ W-2 earnings.

If a Change in Control occurs and vesting of options under the Grant is accelerated, MMC will determine if the Excise Tax is payable by you. If the Excise Tax is payable by you, MMC will pay to you, within five days of making the determination, an amount of money (the “Additional Payment ”) such that after payment of applicable federal, state and local income taxes, employment taxes and any Excise Tax imposed upon the Additional Payment, you will retain an amount of the Additional Payment equal to the Excise Tax imposed in respect of the Accelerated Award. If the Additional Payment, after payment of applicable taxes, is later determined to be less than the amount necessary to reimburse you for the Excise Tax you owe, a further payment will be made to you. If the Additional Payment, after payment of applicable taxes, is later determined to be more than the amount necessary to reimburse you for the Excise Tax you owe, you will be required to reimburse MMC for such excess.

VII. OTHER PROVISIONS

A. Neither the granting of the Grant nor any exercise thereof gives you any right to continue to be employed by the Company, or restricts, in any way, your right or the right of your employer to terminate your employment at any time for any reason not specifically prohibited by law.

B. During your lifetime, an option shall be exercisable only by you, and no right thereunder shall be transferable except by will or the laws of descent and distribution.

C. Neither you nor any person entitled to exercise your rights in the event of your death shall have any of the rights of a stockholder with respect to the shares of MMC common stock subject to an option, unless, and until, you have exercised the option, paid the full exercise price thereof, and have received the shares so acquired.

D. MMC is not liable for the non- issuance or non-transfer, nor for any delay in the issuance or transfer, of any shares of MMC common stock subject to an option or otherwise pursuant to the Plan which results from the inability of MMC to obtain, or in any delay in obtaining, from each regulatory body having jurisdiction, all requisite authority to issue or transfer shares of MMC common stock, if counsel for MMC deems such authority necessary for the lawful issuance or transfer of any such shares.

E. The Grant is subject to all of these terms and conditions and to the terms and conditions of the Plan, and your acceptance of the Grant shall constitute your agreement to the terms and conditions of the Plan and the administrative regulations of the Committee. In the event of any inconsistency between these terms and conditions and the provisions of the Plan, the provisions of the Plan shall prevail. Your acceptance of the Grant constitutes your agreement that the shares of MMC common stock acquired hereunder will not be sold or otherwise disposed of by you in violation of any applicable securities laws or regulations.

I. The Board of Directors may amend, alter, suspend, discontinue or terminate the Plan or the Committee’s authority to grant awards under the Plan, except that, without the consent of an affected participant, no such action ma y materially adversely affect the rights of such participant under any award theretofore granted to him or her. Following the occurrence of a Change in Control (as defined in the Plan), the Board of Directors may not terminate the Plan or amend the Plan with respect to awards that have already been granted in any manner adverse to employees.

J. Awards relating to not more than eighty million (80,000,000) shares of MMC common stock (par value $1.00 per share), plus such number of shares authorized and reserved for awards pursuant to certain preexisting share resolutions adopted by the Board of Directors, may be made over the life of the Plan.

Exhibit 10.42

Section 409A Amendment Regarding

Payments Conditioned Upon Employment-Related Action to

Any and All Plans or Arrangements

Entered into by the Marsh & McLennan Companies, Inc.,

or any of its Direct or Indirect Subsidiaries, that

Provide for the Payment of Section 409A Nonqualified Deferred Compensation

WHEREAS, the American Jobs Creation Act added Section 409A to the Internal Revenue Code of 1986, as amended (“Section 409A”), which, among other things, restricts the time and form of payment of certain nonqualified deferred compensation (“NQDC”) to U.S. taxpayers; and

WHEREAS, Marsh & McLennan Companies, Inc. (“MMCo”) and its direct or indirect operating company subsidiaries (together with MMCo, the “Company”) seek to design compensation to be exempt from Section 409A, but there are instances where an exemption is not or might not be available; and

WHEREAS, in circumstances where any Company arrangement is subject to Section 409A, the Company seeks to ensure that such arrangement complies with Section 409A in both form and operation, taking into account applicable IRS guidance and the advice of counsel; and

WHEREAS, certain Company arrangements may condition payment of NQDC on the completion of one or more employment-related actions, such as the execution and effectiveness of a release of claims or a restrictive covenants agreement (an “Employment-Related Action”) which may be contained in the same document as the terms of the NQDC or in a separate document; and

WHEREAS, the IRS has stated in recent guidance that conditioning NQDC payments on an Employment-Related Action may constitute a form defect under Section 409A if the applicable arrangement is not properly structured; and

WHEREAS, in response to that IRS guidance, the Company has determined that it is desirable to amend all existing plans, awards and arrangements and any such future plans, awards and arrangements (including, without limitation, standardized or form agreements), unless they contain explicit language to the contrary, that provide for the payment of NQDC that is subject to Section 409A and conditioned on an Employment Related Action (together, as further defined below, the “Relevant Plans”). Relevant Plans include: (i) awards granted under the MMCo 2000 Employee Incentive and Stock Award Plan, the MMCo 2000 Senior Executive Incentive and Stock Award Plan or the MMCo 2011 Incentive and Stock Award Plan (collectively, the MMCo Equity Plans”); and (ii) other compensation arrangements including but not limited to, applicable individual employment letters and other agreements, incentive, retention, separation or severance plans, programs and policies, any nonqualified retirement plan, and any other element of compensation for a Company service provider under which payments are conditioned on an Employment-Related Action; and

WHEREAS, the Company’s Chief Human Resources Officer, Laurie Ledford, has general and specific corporate authority to act on behalf of the Company with respect to benefits and compensation matters.

NOW, THEREFORE, to ensure that a service provider cannot affect the taxable year of receipt of NQDC, whether intentionally or inadvertently, by varying the timing of an Employment-Related Action, each Relevant Plan is hereby amended as follows, effective as ofDecember 21, 2012:

(1)    if a Relevant Plan does not specify a deadline for payment to be made or commence, subject to the completion of an Employment-Related Action, or provides for payment to be made or commence, subject to the completion of an Employment-Related Action, within a period of more than 90 days, then the period for payment or commencement of payment, subject to the completion of the applicable Employment Related Action, will be the 90 day period following the event otherwise triggering the right to payment; and

(2)    if the timing of payment under a Relevant Plan could be influenced by the timing of the completion of an Employment-Related Action, and the period for payment or commencement of payment, subject to the completion of an Employment Related Action, (the “Applicable Period”) spans multiple calendar years, then if such Employment Related Action is in fact timely completed or effective, it will be deemed to have been completed on the later of: (a) the first day of the latest calendar year in the Applicable Period, or (b) the date the Employment-Related Action is timely completed.

The foregoing will be deemed to supersede any inconsistent provisions of any Relevant Plan and, in the event of any ambiguity, each Relevant Plan will be interpreted consistent with the requirements of Section 409A pertaining to Employment-Related Actions.

IN WITNESS WHEREOF, Laurie Ledford, in her capacity as the Company’s Chief Human Resources Officer, has executed these amendments on December 27, 2012.

The Plan provides benefits to certain employees of the Company and its participating subsidiaries whose benefits and contributions under the Marsh & McLennan Companies 401(k) Savings & Investment Plan (formerly the Marsh & McLennan Companies Stock Investment Plan) (the "Basic Plan") are limited by certain provisions of the Internal Revenue Code of 1986, as amended (the "Code").

It is intended that benefits paid under the Plan shall be paid under an arrangement that is, for purposes of Employee Retirement Income Security Act of 1974, unfunded and maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees. It is further intended that the Plan complies with the requirements of Section 409A of the Code, including the transition rules issued by the Internal Revenue Service in Notice 2005-1, 2005-1 C.B. 274 and subsequent guidance, to the extent applicable.

The Plan has been amended and restated several times since its establishment, with the most recent restatement effective January 1, 2009 (the “January 2009 Restatement”). The Plan has since been amended.

{00198838-2}    -24-

with the rules of this paragraph (e), the single lump sum distribution as the form of payment. Except in the cases of Disability or death, if a Participant submits a subsequent Distribution Election under this paragraph (e), such election must provide that payment shall be made or commence no sooner than five (5) calendar years from the time such payment otherwise would have been made or would have commenced. For purposes of this paragraph (e), a subsequent Distribution Election shall be effective only if the Distribution Election is made at least twelve (12) months prior to the time of payment specified in the immediately preceding Distribution Election. The annual installment form of payment under Section 5.3 shall be treated as a single payment for purposes of this paragraph (e).

(f)    Default Distribution Election on Account of Disability. In the event a Participant fails to timely submit a completed initial Distribution Election in accordance with Section 2.2 and Section 5.3(c) and becomes Disabled, his or her Post-2004 Benefit shall be paid in a single lump sum in the calendar month, or immediately succeeding calendar month, that a determination has been made that the Participant is Disabled.

(g)    Death Benefit. In the event that a Participant dies before payment of his or her Post-2004 Benefit was made in a single lump sum distribution or commenced to be paid in annual installments, his or her Post-2004 Benefit shall be paid to his or her Beneficiary at the time and in the form designated in the Participant's Distribution Election in effect at the time of death. If no Distribution Election is in effect at the time of the Participant's death, the Post-2004 Benefit shall be paid to his or her Beneficiary in a single lump sum distribution as soon as administratively practicable

{00198838-2}    -25-

following the Participant's date of death but no later than ninety (90) days after such Payment Date. If a Participant dies after annual installments have commenced, payment of the balance of his or her Post-2004 Benefit shall be made to his or her Beneficiary in accordance with his or her Distribution Election; provided, however, if the Distribution Election provided for the continuation of installment payments, then the remaining annual installments shall be paid to the Participant's Beneficiary on the annual installment payment date that is established by the Plan Administrator from time to time that applies to all annual installment payments made under the Plan next following the Participant's date of death.

(h)    Termination of Employment for any Other Reason. Notwithstanding a Participant's Distribution Election made under Section 5.3(c) or (e), in the event that a Participant Terminates Employment for any reason other than Retirement, Disability or death, his or her Post-2004 Benefit shall be paid in a single lump sum distribution as soon as administratively practicable following the date of the Participant's Termination from Employment for any reason other than Retirement, Disability or death, but no later than the 90-day period following such Termination from Employment.

(i)    Determination of Payment Date. Except as may otherwise be provided in Section 5.3(e) with respect to subsequent distribution elections, no Participant or Beneficiary shall have the right to designate the date or taxable year of payment of any distributions to be made under Sections 5.3(c), (d), (g) or (h) of the Plan.

(j)    Specified Employee Rule.    Notwithstanding a Specified Employee's election under Section 5.3(c) or (e) that is effect on his or her Payment Date, the application of the default election rules under Section 5.3(d) or the distribution rules

{00198838-2}    -26-

of Section 5.3(h), the payment or commencement of payment of a Specified Employee's Post-2004 Benefit following his or her Termination from Employment shall not be made or commence before the earlier of (i) the date that is six (6) months following his or her Termination of Employment other than for Disability, or (ii) the date of his or her death.

5.4Source of Payment. The Benefit of each Participant shall be the obligation of the Participating Company or Companies that employed such Participant at the time reductions in the Participant's Compensation were made pursuant to Section 3.1, and shall be the general liability of such Participating Company or Companies. The claim of a Participant or Beneficiary to a Benefit shall at all times be merely the claim of an unsecured creditor of the Participating Company or Companies responsible therefor. No trust, security, escrow, or similar account need be established for the purpose of paying Benefits. However, the Company may in its discretion establish a custodial account or "rabbi trust" (or other arrangement having equivalent taxation characteristics under the Code and applicable regulations or rulings) to hold assets of the Participating Companies, subject to the claims of such Participating Companies' creditors in the event of insolvency, for the purpose of paying Benefits. If the Company establishes such an account or trust, amounts paid therefrom shall discharge the obligations hereunder to the extent of the payments so made.

5.5Change in Control.

(a)    For purposes of Section 5.3 and this Section 5.5, a "Change in Control" shall have occurred if:

{00198838-2}    -27-

(i)    any "person", as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act (the "Exchange Act") (other than the Company, any trustee or other fiduciary holding securities under an employee benefit plan of the Company or any corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of MMC Stock), or more than one person acting as a group is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the combined voting power of the Company's then outstanding voting securities;

(ii)    during any 12-month period, individuals who at the beginning of such period constitute the Board, and any new director whose election by the Board of Directors or nomination for election by the Company's stockholders was approved by a vote of at least a majority of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute at least a majority thereof;

(iii)    there is consummated a merger or consolidation of the Company with any other corporation, other than (A) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving or parent entity) fifty percent (50%) or more of the combined

{00198838-2}    -28-

voting power of the voting securities of the Company or such surviving entity (or any parent of the Company or such surviving entity) outstanding immediately after such merger or consolidation or (B) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no "person" (as herein above defined) or more than one person acting as a group acquired fifty percent (50%) or more of the combined voting power of the Company's then outstanding securities; or

(iv)    during any 12-month period, any person or more than one person acting as a group acquires all or substantially all of the Company's assets (or any transaction having a similar effect); provided that such assets have a total gross fair market value equal to or more than forty percent (40%) of the total gross fair market value of all of the assets of the Company and its subsidiaries.

(b)    Notwithstanding any contrary provision of the Plan, upon the occurrence of a Change in Control, the Company shall pay to each Participant (including a Participant who is a Specified Employee), his or her Benefit (i) in a single distribution of shares of MMC Stock in respect of the number of Notional Shares credited to his or her Account and a single lump sum distribution of cash equal to the Notional Investment Value of his or her Notional Investments credited to his or her Account or (ii) to the extent all of the shares of MMC Stock have been changed, exchanged or converted into cash, property or other securities of the Company in connection with such Change in

{00198838-2}    -29-

Control, in such cash, property or other securities to which such Participant would have been entitled if his or her Benefit had been paid to him or her in the manner as set forth in clause (i) hereof immediately prior to the Change in Control. The Company shall make payments on or after the date of the Change in Control, but in no event shall payment be made later than the latest of (i) the last day of the calendar year in which such Change in Control occurs or (ii) the fifteenth (15^th) day of the third (3^rd) calendar month following the date of the Change in Control, provided that the Participant shall not designate, directly or indirectly, the taxable year of payment.

5.6Payment on Account of Income Inclusion. Notwithstanding any provision in the Plan to the contrary, in the event it is determined at any time that the Plan fails to comply with the requirements of Section 409A of the Code and/or Treasury regulations, a single lump sum distribution shall be paid to an affected Participant within thirty (30) days of such determination. Such payment may not exceed the amount required to be included in the income of such Participant as a result of the failure to comply.

5.7Withholding All deferrals and payments under the Plan shall be subject to any applicable withholding requirements imposed by any tax or other law. The Participating Company or Companies responsible for payment of a Benefit shall have the right to (i) require as a condition of deferral and payment that the payee remit to such Participating Company or Companies an amount sufficient in its or their opinion to satisfy all applicable withholding requirements, or (ii) accelerate the time of a payment, or make a payment from the Plan, in order to pay employment taxes under

{00198838-2}    -30-

Sections 3101, 3121(a) and 3121(v)(2) of the Code, wage withholding under Section 3401 of the Code and wage withholding under applicable state, local and foreign tax law. If the event giving rise to the withholding obligation is the payment of shares of MMC Stock, then the withholding obligation may be satisfied by having the Participating Company or Companies withhold shares of MMC Stock having a Fair Market Value equal to the amount of tax to be withheld. For this purpose, Fair Market Value shall be determined by the Plan Administrator as of the date on which the amount of tax to be withheld is determined.

5.8Delays in Payment. Notwithstanding any other provision of this Article 5, the Plan Administrator may delay the payment of a Benefit in accordance with Treas. Reg. §1.409A-2(b)(7)(i) if the Plan Administrator reasonably anticipates that making the payment would result in the loss of a Participating Company's right to a tax deduction for such payment due to the application of Section 162(m) of the Code. The Plan Administrator may also delay payment of a Benefit in accordance with Treas. Reg. §1.409A-2(b)(7)(ii) if the Plan Administrator reasonably anticipates that the making of the payment will violate Federal securities laws or other applicable law.

{00198838-2}    -31-

{00198838-2}    -35-

ARTICLE 8
AMENDMENT AND TERMINATION

8.1Right Reserved. (a)    Subject to Section 8.2, the Board of Directors may at any time amend or terminate the Plan, retroactively or otherwise, provided that such amendment shall not cause the Plan to violate Section 409A of the Code or Treasury regulations thereunder. However, no such amendment or termination shall reduce any Participant's Benefit determined as though the date of such amendment or termination were the date of his Termination of Employment. The Chief Executive Officer or any officer designated by him also may amend the Plan to the extent permitted under the Employee Benefit Plan Guidelines adopted by the Board of Directors as of September 18, 2003, as from time to time amended.

(b)In its discretion, the Company may upon termination of the Plan or at any time thereafter pay to every Participant (or Beneficiary) in a single distribution a number of shares of MMC Stock equal to the number of Notional Shares credited to his or her Account and a lump sum payment equal to the Notional Investment Value of his or her Notional Investments, whereupon all Accounts shall be terminated; provided, however, no payment shall be made under this paragraph (b) if the termination and liquidation of the Plan does not satisfy any of the permissible circumstances set forth in Treas. Reg. §1.409A-3(j)(4)(ix).

(c)If, upon termination of the Plan, the conditions and circumstances for liquidation of the Accounts under Treas. Reg. §1.409A-3(j)(4)(ix) are not satisfied, no more Eligible Employees shall become Participants, and reductions in

For the purposes of this paragraph (c), Benefits shall be distributed in accordance with Article 5.

8.2Action to Bind Participating Company. Upon the execution of the Plan by the Company, each Participating Company designates the Company as its agent to administer the Plan. Any amendment or termination of the Plan by the Company shall be binding upon each Participating Company.

Reductions in Compensation under Section 3.1 and the associated credits under Section 4.2 and 4.3 shall cease to be credited as Notional Shares effective as of May 14, 2013 or, if earlier, at such time as (a) the aggregate number of shares of MMC Stock paid pursuant to Article 5 on or after May 15, 2003, plus (b) the aggregate number of Notional Shares credited to Participants' Accounts on or after May 15, 2003, equals the share authorization set forth in Section 10.2.

{00198838-2}    -37-

ARTICLE 9
MISCELLANEOUS

9.1Doubt as to Right to Payment. If any doubt exists as to the right of any person to any benefits under this Plan or the amount or time of payment of such benefits (including, without limitation, any case of doubt as to identity, or any case in which any notice has been received from any other person claiming any interest in amounts payable hereunder, or any case in which a claim from other persons may exist by reason of community property or similar laws), the Plan Administrator may, in its discretion, direct that payment of such benefits be deferred until such right or amount or time is determined, or until a court of competent jurisdiction orders that such benefits be paid into court in accordance with appropriate rules of law, or the Plan Administrator may direct that payment be made only upon receipt of a bond or similar indemnification (in such amount and in such form as is satisfactory to the Plan Administrator).

9.2Spendthrift Clause. No benefit, distribution or payment under the Plan may be anticipated, assigned (either at law or in equity), alienated or subject to attachment, garnishment, levy, execution or other legal or equitable process whether pursuant to a "domestic relations order" as defined in Section 414(p) of the Code or otherwise.

9.3Usage. Whenever applicable, the masculine gender, when used in the Plan, includes the feminine gender, and the singular includes the plural.

9.4Data. Any Participant or Beneficiary claiming a Benefit under the Plan shall furnish to the Plan Administrator such documents, evidence or information as t

{00198838-2}    -38-

It is a condition of the Plan that each such Participant or Beneficiary shall furnish promptly true and complete data, evidence or information and sign such documents as the Plan Administrator may require before any benefits become payable under the Plan.

9.5Separability. If any provision of the Plan is determined to be invalid, unenforceable or inconsistent with any applicable law, including Section 409A of the Code, its invalidity, unenforceability or inconsistency with any such applicable law shall not affect any other provisions of the Plan, and the Plan shall be construed and enforced as if such provision had not been included therein. Without limiting the application of the preceding sentence, a provision shall be considered invalid if its operation would cause the Basic Plan to fail to qualify under Section 401(a) of the Code.

9.6Captions. The captions in this document and in the table of contents prefixed hereto are inserted only as a matter of convenience and for reference and in no way define, limit, enlarge or describe the scope or intent of the Plan and shall in no way affect the Plan or the construction of any provision thereof.

9.7Right of Discharge Reserved. The establishment of the Plan shall not be construed to confer upon any employee any legal right to be retained in the employ of a Participating Company or give any employee or any other person any right to benefits, except to the extent expressly provided for hereunder. All employees shall remain subject to discharge to the same extent as if the Plan had never been adopted, a

{00198838-2}    -39-

9.10Governing Law and Limitations on Actions. The Plan is intended to constitute an arrangement that is unfunded and maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees, all within the meaning of the ERISA. All rights under this Plan shall be governed by and construed in accordance with rules of Federal law applicable to such plans. No action (whether at law, in equity or otherwise) shall be brought by or on behalf of any Participant or Beneficiary for or with respect to benefits due under this Plan unless the person bringing such action has timely exhausted the Plan's claim review procedure. Any action (whether at law, in equity or otherwise) must be commenced within three (3) years. This three (3) year period shall be computed from the earlier of (a) the date a final determination denying such benefit, in whole or in part, is issued under the Plan's claim review procedure and (b) the date such individual's c

{00198838-2}    -40-

ause of action first accrued (as determined under the laws of the State of New York without regard to principles of choice of laws).

PREFACE

Marsh & McLennan Companies, Inc. (the “Company”) sponsors and maintains the Marsh & McLennan Companies Benefit Equalization Plan (“BEP”) and the Marsh & McLennan Companies Supplemental Retirement Plan (“SRP”) for the benefit of certain employees. BEP and SRP are separate plans with similar administrative and distribution provisions. They are combined and updated in this document (i) for convenience and to avoid unnecessary duplication of provisions and (ii) to reflect changes made by Section 409A of the Internal Revenue Code of 1986, as amended. However, use of a single document does not effect a merger of BEP and SRP nor in any way affects the independent operation of BEP and SRP. Accordingly, a participant may be entitled to receive benefits under one of these plans, but not the other.

The Company shall have no obligation under BEP or SRP to make any payments or cause any payments to be made except as may be explicitly provided under either plan. The Company shall, as its sole obligation in connection with BEP and SRP, make benefit payments when due out of its general corporate assets, except to the extent that single premium deferred annuity contracts have previously been purchased in satisfaction of previous benefit obligations under either BEP or SRP.

The BEP and SRP were both amended and restated effective January 1, 2009 (the “January 2009 Restatement”). The BEP and SRP have each since been amended. To incorporate the amendments previously made to the January 2009 Restatement and for administrative convenience, the Company hereby restates the Plan in its entirety, effective January 1, 2012.

This document subsumes and restates the Marsh & McLennan Companies Benefit Equalization Plan originally adopted effective January 1, 1988 and as subsequently amended.

Section 1.2.    It is intended that any portion of this Plan which does not constitute an “excess benefit plan,” as defined in Section 3(36) of the Employee Retirement Income Security Act of 1974, shall be an unfunded plan for a select group of management or highly compensated employees to the extent SPDAs (as defined below) have not been purchased on behalf of such employees. It is further intended that this Plan, as amended and restated, shall comply with the requirements of Section 409A of the Code.

(i)    If, at the time of his or her death, the Participant had not attained age fifty-five (55), his or her Domestic Partner’s monthly benefit shall be based on the Participant’s Equalization Benefit determined and actuarially reduced based on the applicable reduction factors provided under the Retirement Plan as of his or her date of death and as if the Participant had elected on the day immediately prior to his or her Normal Retirement Date, had he or she lived, to be paid his or her Equalization Benefit in the form of a Contingent Annuity Option with a 50% survivor’s annuity payable to the Contingent Annuitant. Payment of the survivor’s annuity to the Domestic Partner shall commence on the Participant’s Early Retirement Date, with such date determined as if he or she lived until age fifty-five (55).

(ii)    If, at the time of his or her death, the Participant had attained age fifty-five (55) or greater, his or her Domestic Partner’s monthly benefit shall be based on the Participant’s Equalization Benefit determined and actuarially reduced based on the applicable reduction factors provided under the Retirement Plan on his or her date of death and as if the Participant had elected on the day immediately prior to his or her Normal Retirement Date, had he or she lived, to be paid his or her Equalization Benefit in the form of a Contingent Annuity Option with a 50% survivor’s annuity payable to the Contingent Annuitant.

Section 4.8.    Withholding. All benefits under the Plan, to the extent a Participant’s Equalization Benefit is being paid, shall be subject to any applicable withholding requirements imposed by any tax or other law. Federal employment and hospitalization taxes shall be withheld with respect to the portion of the Participant’s Equalization Benefit at the time payments from this Plan are made. The Company shall have the right to (i) require as a condition of the commencement of the payment of a Participant’s Equalization Benefit that the payee remit to the Company an amount sufficient in its opinion to satisfy all applicable withholding requirements, or (ii) accelerate the time of a payment or make a payment from the Plan, in order to pay employment taxes under Sections 3101, 3121(a) and 3121(v)(2) of the Code, wage withholding under Section 3401 of the Code and wage withholding under applicable state, local and foreign tax law.

Separate Unfunded Plan

Section 6.1.    Severability. The provisions of this Part I (together with other provisions in this document to the extent such provisions are applicable) constitute a separate unfunded plan maintained by the Company.

Section 6.2.    Relationship with Other Company Obligations.

The Company’s obligation to provide any portion of a Participant’s Equalization Benefit has been extinguished upon the purchase of a SPDA with respect to such portion in accordance with the provisions set forth in Schedule A.

Section 6.3.    No Trust Requirement. All amounts payable under this unfunded portion of the Plan shall be paid out of the general assets of the Company, and any individuals entitled to have payments made on their behalf under such unfunded plan shall have no rights to payment greater than the rights of general unsecured creditors of the Company.

However, the Company may, in its sole discretion, establish a domestic “rabbi trust” (or other arrangement having equivalent taxation characteristics under the Code or applicable regulations or rulings) to hold assets, subject to the claims of the Company’s creditors in the event of insolvency, for the purpose of the payment of benefits hereunder. If the Company

{00199467-2}    -31-

establishes such a trust, amounts paid therefrom shall discharge the obligations of the Company hereunder to the extent of the payments so made.

{00199467-2}    -67-

Section 3.5.    Right of Discharge Reserved. The establishment and maintenance of the Plans shall not be construed to confer upon any Employee any legal right to be retained in the employ of a Company or give any Employee or any other person any right to benefits, except to the extent expressly provided for hereunder.

such individual’s cause of action first accrued (as determined under the laws of the State of New York without regard to principles of choice of laws).

Section 3.8.    Section 409A Compliance. Notwithstanding any other provision in the Plans, the terms of each Plan shall in all instances be interpreted in a manner so as to comply with the requirements of Section 409A of the Code and Treasury Regulations issued thereunder.

(b)    Each Custody Agreement provides that the Custodian shall collect all payments under a Participant’s SPDAs, withhold and transmit to appropriate taxing authorities in the Jurisdictions all required withholding taxes, and pay the remainder to the Participant, or to the Participant’s beneficiary or beneficiaries under the SPDA, as the case may be, all in accordance with the terms of the SPDA and the Custody Agreement.

(c)    Each SPDA provides that the issuing insurer shall determine the portion of each SPDA payment that would be taxable by the Jurisdictions to which the Participant is subject. Such determination shall be final and binding for purposes of the Plans. The Committee established uniformly applicable rules and procedures, if and to the extent necessary, to adjust for any situation in which, at any time, the taxable portion (as determined in accordance with the foregoing principles) of a SPDA payment is different with respect to different Jurisdictions.

Section 2.05.    (a) Each time a SPDA was purchased on behalf of a Participant, generally following his termination of employment for any reason other than death, additional Contributions were permitted to be applied by the Company, if necessary, but generally not after December 31, 2002, to purchase insurance on the life of the Participant, the proceeds of which insurance would be payable to the Company, in the event of the Participant’s death before his or her Annuity Starting Date, and applied, as described below, for the benefit of the surviving Qualified Spouse, if any. The amount of such insurance proceeds is required to be at least equal to the excess, if any, of (i) one-half (1/2) of the value immediately before the Participant’s death of his or her vested interest in the SPDAs purchased on behalf of the Participant during his or her lifetime over (ii) the sum of (A) the value as of the date of the Participant’s death of the pre-retirement survivor annuity, if any, payable under such SPDAs, plus (B) the value (determined as of such date in accordance with the funding methods and assumptions utilized under the Retirement Plan) of a Single Life Annuity that could provide for annual payments to such surviving Qualified Spouse, commencing as soon as practicable after the Participant’s death, in an amount which, after reduction by the amount of Applicable Taxes on the taxable portion thereof (determined as if such Single Life Annuity were provided under such SPDAs) would equal the product of (I) one minus the Applicable Tax Rate, multiplied by (II) the excess, if any, of (x) the Actual Benefit payable to such surviving Qualified Spouse without regard to any pre-retirement survivor annuity elections that may have been made under the Retirement Plan, over (y) the pre-retirement survivor annuity that would be payable to such surviving Qualified Spouse under the Retirement Plan applying the limitations of Section 415 of the Code to such annuity.

{00199467-2}    -77-

(b)    To the extent practicable or required by law, upon such Participant’s death before his or her Annuity Starting Date, the proceeds of any insurance described above shall be applied, through the purchase of an SPDA or otherwise, for the benefit of the surviving Qualified Spouse, if any.

(c)    The Plan Administrator may establish such procedures as it deems appropriate to ensure that the appropriate amount of insurance, if any, shall be in force at all times until each Participant’s Annuity Starting Date.

Section 2.06.    Rules for Determining Amount of Contributions.

(a)    The rules of this Section determined the amount of Contributions that were utilized to purchase an SPDA.

(b)    The Participant’s Equalization Benefit, Supplemental Benefit, Formula Benefit and Actual Benefit were determined on the basis of the Participant’s actual age and service and salary history on the applicable SPDA Valuation Date, and on the assumption that benefit payments would commence on the then earliest date retirement benefits under the Retirement Plan could commence to be paid with respect to the Participant and that all necessary retirement and other elections were duly made; provided, however, that the Actual Benefit was also determined, except in the case of an SPDA purchased after termination of employment, on the basis of the projected maximum allowable benefit payable to or in respect of the Participant at such earliest date under the Tax Limitations, as adjusted in accordance with applicable law enacted and not repealed as of the date of such determination, and provided further that such projection was determined by the enrolled actuary regularly engaged for the Retirement Plan or

{00199467-2}    -78-

such other actuary chosen by the Plan Administrator in its sole discretion, and the determination of such actuary was and shall be final and binding on all parties.

(c)    Applicable Taxes and the Applicable Tax Rate were determined on the assumption that the Participant for whom the SPDA was purchased would be subject to the same Jurisdictions when payments under the SPDAs begin as the Jurisdictions to which the Participant is subject when such SPDA was purchased, but taking into account all future changes in income tax rates scheduled, in accordance with applicable law enacted and not repealed as of the date of purchase, to go into effect in such Jurisdictions by the date payments under the SPDAs begin.

(d)    The amount of Applicable Taxes was determined by multiplying the Applicable Tax Rate by the taxable portion, as determined by the insurer issuing an SPDA, of each payment that could be provided to the Participant under the SPDAs, and totaling the products thus obtained.

Section 2.07.    SPDA Terms.

(a)    Each SPDA contains terms consistent with the requirements of each Plan under which an individual is a Participant.

(b)    Each SPDA permits payments to be made to the Participant commencing at, but not before, the earliest date the Participant could elect to commence receiving benefits under the Retirement Plan or at any later date, and in any form permitted under the Retirement Plan at the time such SPDA is purchased.

(c)    Each SPDA provides that it may not be surrendered, in whole or in part, in exchange for payment of a surrender value.

Section 2.08.    Custodian.

{00199467-2}    -79-

(a)    Each Participant on behalf of whom an SPDA was purchased under the Benefit Equalization Plan or Supplemental Plan has selected a bank or other financial institution as Custodian to hold all SPDAs purchased on behalf of such Participant, provided that the Participant executed a Custody Agreement with such Custodian. A Participant’s selection of a Custodian, and the related Custody Agreement, are subject to approval by the Company, which approval may not have been unreasonably withheld.

(b)    The Custodian selected by a Participant holds all SPDAs purchased on behalf of such Participant under the Plans and collects and accumulates payments made under such SPDAs pending the distribution of such payments pursuant to the terms of each Plan. A Participant shall have all rights, title and interests in and to all assets held by the Custodian, subject only to the terms and conditions set forth in each Plan, the Custody Agreement and the SPDAs.

(c)    The Company afforded the affected Participants an opportunity to select an individual to serve as each Participant’s Representative to represent such Participant in dealings with the Custodian(s). To the extent that the Plan Administrator has been selected as the Participant’s Representative, all actions taken by the Plan Administrator in his capacity as the Participant’s Representative are and shall be solely as the agent of the Participant and not in any other capacity. The Company pays the reasonable expenses incurred by the Participant’s Representative in the discharge of his duties to the Participant.

Section 2.09.    Payment of Tax Withholding.

(a)    Within a reasonable time after a Contribution had been used to purchase an SPDA, the Company paid income tax withholding for such Participant, and notified such

{00199467-2}    -80-

individual in writing of the amount so paid as soon as possible thereafter but in no event later than thirty (30) days after the close of the Plan Year in which such purchase occurred.

(b)    Such income tax withholding was paid to each Jurisdiction on or before the due date for applicable income tax withholding on wages taxable by such Jurisdiction at the time such Contribution was so used.

(c)    Notwithstanding the minimum income tax withholding requirements of such Jurisdiction, the amount of such income tax withholding payment is equal to the product obtained by multiplying (i) the sum of (A) the Contribution plus (B) the amount of such payment by (ii) the Applicable Tax Rate on such date; provided, however, that, if a different withholding payment was required by applicable law, the Plan Administrator, pursuant to uniformly applicable rules and procedures, required appropriate adjustments to any terms of any of the Plans.

Section 2.10.    Authorizations. Notwithstanding the foregoing, the Company has no obligations with respect to any Participant or his Qualified Spouse unless such Participant executes such authorizations, if any, as may be necessary for the income tax withholding payments required by this Article to be made.

Section 2.11.    Separate Obligation. The Company’s obligations, if any, to make payments (or to correct or adjust any payment as the Company, in its sole and absolute discretion, deems to be necessary or appropriate) described in this Schedule A are deemed to be direct obligations of the Company, and such obligations do not arise under the separate Plans that are unfunded.

{00199467-2}    -81-

Section 2.12.    Capitalized Terms. Capitalized terms used in this Schedule A (other than terms otherwise defined herein) that are defined in a Plan shall have the meaning set forth in the Plan.

Exhibit 10.53

NON-COMPETITION AND NON-SOLICITATION AGREEMENT

AGREEMENT, effective as of September 19, 2012, between Marsh & McLennan Companies, Inc. (the “Company”) and J. Michael Bischoff, an employee of the Company (“Executive”).

RECITALS:

This Agreement is entered into in consideration of the (a) Executive’s employment by the Company in a senior executive position, (b) Executive’s eligibility for certain bonus compensation as an employee of the Company, and (c) Executive’s access to confidential information and trade secrets belonging to the Company.

NOW, THEREFORE, the Company and Executive hereby agree to be bound by this Non-Competition and Non-Solicitation Agreement, as follows:

1.Confidential Information and Trade Secrets

(a)Executive understands and acknowledges that as an executive of the Company, Executive will learn or have access to, or may assist in the development of, highly confidential and sensitive information and trade secrets about the Company, its operations and its clients, and that providing its clients with appropriate assurances that their confidences will be protected is crucial to the Company’s ability to obtain clients, maintain good client relations, and conform to contractual obligations. Such Confidential Information and Trade Secrets include but are not limited to: (i) financial and business information relating to the Company, such as information with respect to costs, commissions, fees, profits, sales, markets, mailing lists, strategies and plans for future business, new business, product or other development, potential acquisitions or divestitures, and new marketing ideas; (ii) product and technical information relating to the Company, such as product formulations, new and innovative product ideas, methods, procedures, devices, machines, equipment, data processing programs, software, software codes, computer models, and research and development projects; (iii) client information, such as the identity of the Company’s clients, the names of representatives of the Company’s clients responsible for entering into contracts with the Company, the amounts paid by such clients to the Company, specific client needs and requirements, specific client characteristics related to the provision of services by the Company, client consulting needs and information about the consulting services provided by the Company, client insurance policy information, information regarding the markets or sources with which insurance is placed, and leads and referrals to prospective clients; (iv) personnel information, such as the identity and number of the Company’s other employees, their salaries, bonuses, benefits, skills, qualifications, and abilities; (v) any and all information in whatever form relating to any client or prospective client of the Company, including but not limited to, its business, employees, operations, systems, assets, liabilities, finances, products, and marketing, selling and operating practices; (vi) any information not included in (i) or (ii) above which Executive knows or should know is subject to a restriction on disclosure or which Executive knows or should know is considered by the Company or the Company's clients or prospective clients to be confidential, sensitive, proprietary or a trade secret or is not readily available to the public; and (vii) intellectual property, including inventions and copyrightable works. Confidential Information and Trade Secrets are not generally known or available to the general public, but have been developed, compiled or acquired by the Company at its great effort and expense. Confidential Information and Trade Secrets can

Page 2

be in any form, including but not limited to: oral, written or machine readable, including electronic files.

(b)Executive acknowledges and agrees that the Company is engaged in a highly competitive business and that its competitive position depends upon its ability to maintain the confidentiality of the Confidential Information and Trade Secrets which were developed, compiled and acquired by the Company at its great effort and expense. Executive further acknowledges and agrees that any disclosing, divulging, revealing, or using of any of the Confidential Information and Trade Secrets, other than in connection with the Company’s business or as specifically authorized by the Company, will be highly detrimental to the Company and cause it to suffer serious loss of business and pecuniary damage.

(c)At all times prior to and following Executive’s termination of employment, Executive shall not disclose to anyone or make use of any Confidential Information and Trade Secrets of the Company or any subsidiary, including such trade secret or proprietary or confidential information of any customer or client or other entity to which the Company or any subsidiary owes an obligation not to disclose such information, which Executive acquires during Executive’s employment with the Company or any subsidiary, including but not limited to records kept in the ordinary course of business except: (i) as such disclosure or use may be required or appropriate in connection with Executive’s work as an employee of the Company or any subsidiary; (ii) when required to do so by a court of law, by any governmental agency having supervisory authority over the business of the Company or any subsidiary or by any administrative or legislative body (including a committee thereof) with apparent jurisdiction to order Executive to divulge, disclose or make accessible such information; or (iii) as to such confidential information that becomes generally known to the public or trade without Executive’s violation of this Agreement.

(d)Immediately upon the termination of employment with the Company for any reason, or at any time the Company so requests, Executive will return to the Company: (i) any originals and all copies of all files, notes, documents, slides (including transparencies), computer disks, printouts, reports, lists of the Company’s clients or leads or referrals to prospective clients, and other media or property in Executive’s possession or control which contain or pertain to Confidential Information and Trade Secrets; and (ii) all property of the Company, including but not limited to supplies, keys, access devices, books, identification cards, computers, telephones and other equipment. Executive agrees that upon completion of the obligations set forth in this subparagraph and if requested by the Company, Executive will execute a statement in a form provided by the Company declaring that he has retained no property of the Company or materials containing Confidential Information and Trade Secrets nor has he supplied the same to any person, except as required to carry out his duties as an executive of the Company

2.Non-Competition

(a)    Executive acknowledges and agrees that the Company is engaged in a highly competitive business and that by virtue of Executive’s position and responsibilities with the Company and Executive’s access to the Confidential Information and Trade Secrets, engaging in any business which is directly competitive with the Company will cause it great and irreparable harm.

(b)    Accordingly, both during Executive’s employment with the Company or any subsidiary and during the twelve (12) month period following the cessation of Executive’s employment with the Company or any subsidiary, whether voluntarily or involuntarily and for any reason, Executive shall not, without the express written consent of the Chief Executive Officer of the Company, directly or indirectly own, manage, operate or control, or be employed in a capacity similar to the position(s) held by Executive with the Company by any company or entity engaged in such segment(s) of the Company’s Business for which Executive had responsibility or about which Executive had knowledge of or access to Confidential Information and Trade Secrets while

Page 3

employed by the Company. For purposes of this Agreement, the Company’s “Business” means the provision of services of the type provided by the Company and its subsidiaries and affiliates, including but not limited to insurance brokerage, risk management, reinsurance, management, human resource and benefit consulting, and outsourcing and investment services. In recognition of the international nature of the Company’s Business which includes the sale of its products and services globally, this restriction shall apply in all countries throughout the world where the Company does business as of the date of termination of Executive’s employment with the Company. It is specifically agreed and understood that Executive’s acceptance of employment with a company or entity engaged in the Company’s Business following termination of Executive’s employment with the Company is not prohibited by this Agreement.

3.Non-Solicitation of Clients

(a)Executive acknowledges and agrees that solely by reason of employment by the Company, Executive has and will come into contact with a significant number of the Company’s clients and prospective clients and have access to Confidential Information and Trade Secrets relating thereto, including those regarding the Company’s clients, prospective clients and related information.

(b)    Consequently, during the twelve (12) month period following the cessation of Executive’s employment with the Company or any subsidiary, whether voluntarily or involuntarily and for any reason, Executive shall not, without the express written consent of the Chief Executive Officer of the Company, directly or indirectly: (i) solicit clients of the Company for the purpose of selling or providing products or services of the type sold or provided by Executive while employed by the Company; or (ii) induce clients or prospective clients of the Company to terminate, cancel, not renew, or not place business with the Company; (iii) perform or supervise the performance of services or provision of products of the type sold or provided by Executive while he was employed by the Company on behalf of any clients or prospective clients of the Company; or (iv) assist others to do the acts specified in Sections 3(b) (i)-(iii). This restriction shall apply only to those clients or prospective clients of the Company with whom Executive had contact or about whom Executive obtained Confidential Information and Trade Secrets during the last two (2) years of Executive’s employment with the Company. For the purposes of this Section, the term “contact” means interaction between Executive and the client which takes place to further the business relationship, or making (or assisting or supervising the performance or provision of) sales to or performing or providing (or assisting or supervising the performance or provision of) services or products for the client on behalf of the Company. For purposes of this Section 3, the term “contact” with respect to a “prospective” client means interaction between Executive and a potential client of the Company which takes place to obtain the business of the potential client on behalf of the Company. It shall not be a defense to a claim that this Section has been breached that Executive’s new employer or entity for which Executive is performing services has previously solicited or served the client.

4.Non-Solicitation of Employees

Executive acknowledges and agrees that solely as a result of employment with the Company, and in light of the broad responsibilities of such employment which include working with other employees of the Company, Executive has and will come into contact with and acquire Confidential Information and Trade Secrets regarding the Company’s other employees. Accordingly, during Executive’s employment with the Company or any subsidiary and during the twelve (12) month period following the cessation of Executive’s employment with the Company or any subsidiary, whether voluntarily or involuntarily and for any reason, Executive shall not, without the express written consent of the Chief Executive Officer of the Company, either on Executive’s own account or on behalf of any person, company, corporation, or other entity, directly or indirectly, solicit, or endeavor to cause any employee of the Company with whom Executive, during the last two (2) years of his employment with the Company, came into contact for the purpose of soliciting

Page 4

or servicing business or about whom Executive obtained Confidential Information and Trade Secrets to leave employment with the Company.

5.Enforcement

(a)    Executive acknowledges and agrees that the covenants contained in this Agreement are reasonable and necessary to protect the confidential information and goodwill of the Company and its subsidiaries. Executive further represents that his experience and capabilities are such that the provisions of this Agreement will not prevent him from earning a livelihood.

(b)    Executive acknowledges and agrees that compliance with the covenants set forth in this Agreement is necessary to protect the Confidential Information and Trade Secrets, business and goodwill of the Company, and that any breach of this Agreement will result in irreparable and continuing harm to the Company, for which money damages may not provide adequate relief. Accordingly, in the event of any breach or anticipatory breach of this Agreement by Executive, or Executive’s claim in a declaratory judgment action that all or part of this Agreement is unenforceable, the parties agree that the Company shall be entitled to the following particular forms of relief as a result of such breach, in addition to any remedies otherwise available to it at law or equity: (a) injunctions, both preliminary and permanent, enjoining or restraining such breach or anticipatory breach, and Executive hereby consents to the issuance thereof forthwith and without bond by any court of competent jurisdiction; and (b) recovery of all reasonable sums and costs, including attorneys’ fees, expert witness fees, expenses and costs incurred by the Company to defend or enforce the provisions of this Agreement.

(c)    In the event the Company is required to enforce any of its rights hereunder through legal proceedings, the parties acknowledge that it may be difficult or impossible to ascertain the precise amount of damages or lost profits incurred by the Company. Therefore, in the event of any breach by Executive of Section 3 of this Agreement, in addition to any other relief available to the Company at law or in equity, Executive agrees that the damages for each client lost in whole or in part by the Company as a result of my breach shall be two hundred percent (200%) of the gross commissions and fees received by the Company from such client during the twelve (12) months preceding the cessation of my employment. In arriving at this calculation, Executive agrees that the Company and Executive have considered the following factors: (i) the value of the clients; (ii) the business of the Company; (iii) the type and quality of the clients; (iv) the substantial amount of time, effort and expense incurred by the Company in acquiring, developing and maintaining the clients; (v) the number of years the Company typically retains such clients; (vi) the profitability of renewal business; and (vii) various other factors relating to the relationship between the Company and the clients. Executive further agrees that Executive shall be obligated to reimburse the Company for all reasonable costs, expenses and counsel fees incurred by the Company in connection with the enforcement of its rights hereunder.

(d)    The restrictive periods set forth in this Agreement (including those set forth in Sections 2, 3 and 4 hereof) shall not expire and shall be tolled during any period in which Executive is in violation of such restrictive periods, and therefore such restrictive periods shall be extended for a periods equal to the durations of Executive’s violations thereof.

6.Employment At-Will

Executive understands that this Agreement does not constitute a contract of employment and does not promise or imply that his employment will continue for any period of time. Unless otherwise agreed to under any employment agreement between Executive and the Company whether executed prior to this Agreement or at any time hereafter, employment with the Company is “at will” and may be terminated either by Executive or the Company at any time, with or without cause, and with or without notice.

Page 5

7.Miscellaneous

(a)    Governing Law; Choice of Forum. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to its conflict of laws provisions. The parties, being desirous of having any disputes resolved in a forum having a substantial body of law and experience with the matters contained herein, agree that any action or proceeding with respect to this Agreement and Executive’s employment shall be brought exclusively in the Civil Court of the City of New York, New York County, or in the Supreme Court of the State of New York, New York County, or in the United States District Court for the Southern District of New York, and the parties agree to the personal jurisdiction thereof. The parties hereby irrevocably waive any objection they may now or hereafter have to the laying of venue of any such action in the said court(s), and further irrevocably waive any claim they may now or hereafter have that any such action brought in said court(s) has been brought in an inconvenient forum. Executive recognizes that, should any dispute or controversy arising from or relating to this agreement be submitted for adjudication to any court, arbitration panel or other third party, the preservation of the secrecy of Confidential Information and Trade Secrets may be jeopardized. Consequently, Executive agrees that all issues of fact shall be severed for trial without a jury.

(b)    Severability. The parties agree they have attempted to limit the scope of the post-employment restrictions contained herein to the extent necessary to protect Confidential Information and Trade Secrets, client relationships and goodwill. It is the desire and intent of the parties that the provisions of this Agreement shall be enforced to the fullest extent permissible under applicable laws and public policies. Accordingly, if any particular portion of this Agreement shall be adjudicated to be invalid or unenforceable, this Agreement shall be deemed amended to delete therefrom such invalid portion, and reformed to the extent valid and enforceable. Such deletion and reformation shall apply only with respect to the operation of this Agreement in the particular jurisdiction in which such adjudication is made.

(c)    Modification. No modification of this Agreement shall be valid unless made in a written or electronic instrument signed by both parties hereto, wherein specific reference is made to this Agreement.

(d)    Non-Waiver. The failure of either the Company or Executive, whether purposeful or otherwise, to exercise in any instance any right, power, or privilege under this Agreement or under law shall not constitute a waiver of the same or any other right, power, or privilege in any other instance. Any waiver by the Company or by Executive must be in a written or electronic instrument signed by either Executive, if Executive is seeking to waive any of his rights under this Agreement, or by the Chief Executive Officer of the Company, if the Company is seeking to waive any of its rights under this Agreement.

(e)    Binding Effect. This Agreement shall be binding upon Executive, Executive’s heirs, executors and administrators, and upon the Company, and its successors and assigns, and shall inure to the benefit of the Company, and its successors and assigns. This Agreement may not be assigned by Executive. This Agreement may be enforced by the Company’s successors and assigns

(f)    Other Agreements. This Agreement contains the entire agreement between Executive and the Company with respect to the subject matter hereof, and supersedes and terminates any and all previous agreements and understandings between Executive and the Company, whether written or oral, with respect to noncompetition or nonsolicitation restrictions. The obligations under this Agreement also shall survive any changes made in the future to the employment terms of Executive, including but not limited to changes in operating company salary, benefits, bonus plans, job title and job responsibilities.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and year first hereinabove set forth.

[ADDRESS]

Dear Brian,

I am pleased to inform you that the Compensation Committee met today and determined that your termination of employment qualifies as a “qualifying retirement” under your September 17, 2009 employment letter. This determination will result in the third tranche of 400,000 performance-contingent stock options that were granted to you in January 2008 vesting and becoming exercisable (i.e., performance conditions lapsing) and such stock options remaining outstanding for five years following your termination of employment, provided that you execute and deliver to Marsh & McLennan Companies, Inc. (the “Company”) the enclosed General Release and it becomes irrevocable. The enclosed General Release is substantially the form attached as Exhibit A to your January 29, 2008 employment agreement, with updates to refer to your September 17, 2009 employment letter and corresponding sections therein.

The Committee also considered your request for post-retirement transitional support. You will be provided with administrative support, an office at the Company's office in Bermuda and access to your existing email and phone numbers through December 31, 2013. You may also continue to use your Bloomberg subscription until it expires in February 2014 and retain the iPhone, Blackberry, and two iPads issued to you by the Company.

Sincerely,

Without limiting the generality of the foregoing terms, this General Release specifically includes all claims based on the terms, conditions, and privileges of employment, and those based on breach of contract (express or implied), tort, harassment, intentional infliction of emotional distress, defamation, negligence, privacy, employment discrimination, retaliation, discharge not for just cause, constructive discharge, wrongful discharge, the Age Discrimination in Employment Act of 1967, as amended (the “ADEA”), the Older Workers Benefit Protection Act of 1990, the Worker Adjustment and Retraining Notification Act, as amended, Executive Order 11,141 (age discrimination), Title VII of the Civil Rights Act of 1964, as amended, the Civil Rights Act of 1991, the Civil Rights Act of 1866 and 1871, Sections 1981 through 1988 of Title 42 of the United States code, as amended, 41 U.S.C. §1981 (discrimination), 29 U.S.C. §206(d)(1) (equal pay), Executive Order 11,246 (race, color, religion, sex and national origin discrimination), the National Labor Relations Act, the Equal Pay Act of 1993, the Americans with Disabilities Act of 1990, the Occupational Safety and Health Act, as amended, the Family Medical Leave Act, the Immigration Reform and Control Act, as amended, the Vietnam Era Veterans Readjustment Assistance Act, §§503-504 of the Rehabilitation Act of 1973 (handicap rehabilitation), the Employee Retirement Income Security Act of 1974, as amended, any federal, state or local fair employment, civil or human rights, wage and hour laws and wage payment laws, and any and all other Federal, state, local or other governmental statutes, laws, ordinances, regulations and orders, under common law, and under any Company policy, procedure, bylaw or rule.

required by state or Federal law) or claims arising under the terms of any applicable plan, program or other arrangement of Company.

2.         Executive intends this General Release to be binding on his successors, and Executive specifically agrees not to file or continue any claim in respect of matters covered by Section 1, above. Executive further agrees never to institute any suit, complaint, proceeding, grievance or action of any kind at law, in equity, or otherwise in any court of the United States or in any state, or in any administrative agency of the United States or any state, county or municipality, or before any other tribunal, public or private, against Company arising from or relating to his employment with or his termination of employment from Company and/or any other occurrences to the date of this General Release, other than a claim challenging the validity of this General Release under the ADEA or respecting any matters not covered by this General Release.

3.         Executive is further waiving his right to receive money or other relief in any action instituted by him or on his behalf by any person, entity or governmental agency in respect of matters covered by this General Release. Nothing in this General Release shall limit the rights of any governmental agency or his right of access to, cooperation or participation with any governmental agency, including without limitation, the United States Equal Employment Opportunity Commission. Executive further agrees to waive his rights under any other statute or regulation, state or federal, which provides that a general release does not extend to claims which Executive does not know or suspect to exist in his favor at the time of executing this General Release, which if known to him must have materially affected his settlement with Company.

4.         Executive agrees that Executive shall not be eligible and shall not seek or apply for reinstatement or re-employment with Company and agrees that any application for re-employment may be rejected without explanation or liability pursuant to this provision.

5.         In further consideration of the promises made by Company in this General Release, Executive specifically waives and releases Company, to the extent set forth in Section 1 hereof, from all claims Executive may have as of the date of this General Release, whether known or unknown, arising under the ADEA. Executive further agrees that:

a) Executive’s waiver of rights under this General Release is knowing and voluntary and in compliance with the Older Workers Benefit Protection Act of 1990 (“OWBPA”);

b) Executive understands the terms of this General Release;

c) The consideration offered by Company under Section 3(b) of the Employment Letter in exchange for the General Release represents consideration over and above that to which Executive would otherwise be entitled, and that the consideration would not have been provided had Executive not agreed to sign the General Release and did not sign the Release;

d) Company is hereby advising Executive in writing to consult with an attorney prior to executing this General Release;

e) Company is giving Executive a period of twenty-one (21) days within which to consider this General Release;

f) Following Executive’s execution of this General Release, Executive has seven (7) days in which to revoke this General Release by written notice. An attempted revocation not actually received by Company prior to the revocation deadline will not be effective; and

g) This General Release and the treatment of long-term incentive awards set forth in Section 3(b) of the Employment Letter shall be void and of no force and effect if Executive chooses to so revoke, and if Executive chooses not to so revoke, this General Release shall then become effective and enforceable.

6.         This General Release does not waive rights or claims that may arise under the ADEA after the date Executive signs this General Release. To the extent barred by the OWBPA, the covenant not to sue contained in Section 2, above, does not apply to claims under the ADEA that challenge the validity of this General Release.

7.         To revoke this General Release, Executive must send a written statement of revocation to:

Exhibit 10.64

NON-COMPETITION AND NON-SOLICITATION AGREEMENT

AGREEMENT, dated as of April 20, 2011, between Guy Carpenter & Company LLC and/or subsidiaries thereof (the “Employer”), the parents and affiliates of which comprise Marsh & McLennan Companies, Inc. (the “Company”), and Alexander Moczarski, an employee of the Employer (the “Executive”).

RECITALS:

This Agreement is entered into in consideration of the (a) Executive’s employment by the Employer in a senior executive position, (b) Executive’s eligibility for certain bonus compensation of Employer, and (c) Executive’s access to confidential information and trade secrets belonging to Employer.

NOW, THEREFORE, the Employer and the Executive hereby agree to be bound by this Non-Competition and Non-Solicitation Agreement, as follows:

1.Confidential Information and Trade Secrets

(a)Executive understands and acknowledges that as an executive of the Company, Executive will learn or have access to, or may assist in the development of, highly confidential and sensitive information and trade secrets about the Company, its operations and its clients, and that providing its clients with appropriate assurances that their confidences will be protected is crucial to the Company’s ability to obtain clients, maintain good client relations, and conform to contractual obligations. Such Confidential Information and Trade Secrets include but are not limited to: (i) financial and business information relating to the Company, such as information with respect to costs, commissions, fees, profits, sales, markets, mailing lists, strategies and plans for future business, new business, product or other development, potential acquisitions or divestitures, and new marketing ideas; (ii) product and technical information relating to the Company, such as product formulations, new and innovative product ideas, methods, procedures, devices, machines, equipment, data processing programs, software, software codes, computer models, and research and development projects; (iii) client information, such as the identity of the Company’s clients, the names of representatives of the Company’s clients responsible for entering into contracts with the Company, the amounts paid by such clients to the Company, specific client needs and requirements, specific client risk characteristics, policy expiration dates, policy terms and conditions, information regarding the markets or sources with which insurance is placed, and leads and referrals to prospective clients; (iv) personnel information, such as the identity and number of the Company’s other employees, their salaries, bonuses, benefits, skills, qualifications, and abilities; (v) any and all information in whatever form relating to any client or prospective client of the Company, including but not limited to, its business, employees, operations, systems, assets, liabilities, finances, products, and marketing, selling and operating practices; (vi) any information not included in (i) or (ii) above which Executive knows or should know is subject to a restriction on disclosure or which Executive knows or should know is considered by the Company or the Company's clients or prospective clients to be confidential, sensitive, proprietary or a trade secret or is not readily available to the public; and (vii) intellectual property, including inventions and copyrightable works. Confidential Information and Trade Secrets are not generally known or available to the general public, but have been developed, compiled or acquired by the Company

at its great effort and expense. Confidential Information and Trade Secrets can be in any form: oral, written or machine readable, including electronic files.

(b)Executive acknowledges and agrees that the Company is engaged in a highly competitive business and that its competitive position depends upon its ability to maintain the confidentiality of the Confidential Information and Trade Secrets which were developed, compiled and acquired by the Company at its great effort and expense. Executive further acknowledges and agrees that any disclosing, divulging, revealing, or using of any of the Confidential Information and Trade Secrets, other than in connection with the Company’s business or as specifically authorized by the Company, will be highly detrimental to the Company and cause it to suffer serious loss of business and pecuniary damage.

(c)At all times prior to and following the Executive’s termination of employment, the Executive shall not disclose to anyone or make use of any trade secret or proprietary or confidential information of the Company or any subsidiary, including such trade secret or proprietary or confidential information of any customer or client or other entity to which the Company or any subsidiary owes an obligation not to disclose such information, which the Executive acquires during the Executive’s employment with the Company or any subsidiary, including but not limited to records kept in the ordinary course of business except: (i) as such disclosure or use may be required or appropriate in connection with the Executive’s work as an employee of the Company or any subsidiary; (ii) when required to do so by a court of law, by any governmental agency having supervisory authority over the business of the Company or any subsidiary or by any administrative or legislative body (including a committee thereof) with apparent jurisdiction to order the Executive to divulge, disclose or make accessible such information; or (iii) as to such confidential information that becomes generally known to the public or trade without the Executive’s violation of this Agreement.

(d)Immediately upon the termination of employment with the Company for any reason, or at any time the Company so requests, Executive will return to the Company: (i) any originals and all copies of all files, notes, documents, slides (including transparencies), computer disks, printouts, reports, lists of the Company’s clients or leads or referrals to prospective clients, and other media or property in Executive’s possession or control which contain or pertain to Confidential Information or Trade Secrets; and (ii) all property of the Company, including but not limited to supplies, keys, access devices, books, identification cards, computers, telephones and other equipment. Executive agrees that upon completion of the obligations set forth in this subparagraph and if requested by the Company, Executive will execute a statement in a form provided by the Company declaring that he or she has retained no property of the Company or materials containing Confidential Information nor has he or she supplied the same to any person, except as required to carry out his or her duties as an executive of the Company.

2.Non-Competition

(a)    Executive acknowledges and agrees that the Company is engaged in a highly competitive business and that by virtue of Executive’s position and responsibilities with the Company and Executive’s access to the Confidential Information and Trade Secrets, engaging in any business which is directly competitive with the Company will cause it great and irreparable harm.

(b)    Accordingly, both during the Executive’s employment with the Company or any subsidiary and during the twelve (12) month period following the cessation of the Executive’s employment with the Company or any subsidiary, whether voluntarily or involuntarily and for any reason, the Executive shall not, without the express written consent of the Chief Executive Officer of the Company, directly or indirectly own, manage, operate or control, or be employed in a capacity

similar to the position(s) held by Executive with the Company by any company or entity engaged in such segment(s) of the Company’s Business for which Executive had responsibility or about which Employee had knowledge of or access to Confidential Information and Trade Secrets while employed by the Company. For purposes of this Agreement, the Company’s “Business” means the provision of insurance brokerage and risk management services of the type provided by the Company and its subsidiaries and affiliates. In recognition of the international nature of the Company’s Business which includes the sale of its products and services globally, this restriction shall apply in all countries throughout the world where the Company does business as of the date of termination of the Executive’s employment with the Company. It is specifically agreed and understood that the Executive’s acceptance of employment with an insurance or reinsurance carrier following termination of Executive’s employment with the Company is not prohibited by this Agreement.

3.Non-Solicitation of Clients

(a)The Executive acknowledges and agrees that solely by reason of employment by the Company, the Executive has and will come into contact with a significant number of the Company’s clients and prospective clients and have access to Confidential Information and Trade Secrets relating thereto, including those regarding the Company’s clients, prospective clients and related information.

(b)    Consequently, during the twelve (12) month period following the cessation of the Executive’s employment with the Company or any subsidiary, whether voluntarily or involuntarily and for any reason, the Executive shall not, without the express written consent of the Chief Executive Officer of the Company, directly or indirectly: (i) solicit clients of the Company for the purpose of selling or providing products or services of the type sold or provided by the Executive while employed by the Company; or (ii) induce clients or prospective clients of the Company to terminate, cancel, not renew, or not place business with the Company; or (iii) perform or supervise the performance of services or provision of products of the type sold or provided by the Executive while he or she was employed by the Company on behalf of any clients or prospective clients of the Company. This restriction shall apply only to those clients or prospective clients of the Company with whom the Executive had contact or about whom the Executive obtained Confidential Information or Trade Secrets during the last two (2) years of his or her employment with the Company. For the purposes of this Section, the term “contact” means interaction between the Executive and the client which takes place to further the business relationship, or making (or assisting or supervising the making of) sales to or performing or providing (or assisting or supervising the performance or provision of) services or products for the client on behalf of the Company. For purposes of this Section 2, the term “contact” with respect to a “prospective” client means interaction between the Executive and a potential client of the Company which takes place to obtain the business of the potential client on behalf of the Company.

4.Non-Solicitation of Employees

The Executive acknowledges and agrees that solely as a result of employment with the Company, and in light of the broad responsibilities of such employment which include working with other employees of the Company, the Executive has and will come into contact with and acquire confidential information and trade secrets regarding the Company’s other employees. Accordingly, during the Executive’s employment with the Company or any subsidiary and during the twelve (12) month period following the cessation of the Executive’s employment with the Company or any subsidiary, whether voluntarily or involuntarily and for any reason, the Executive shall not, without the express written consent of the Chief Executive Officer of the Company the Executive shall not, either on the Executive’s own account or on behalf of any person, company, corporation, or other entity, directly or indirectly, solicit, or endeavor to cause any employee of the Company with whom the Executive, during the last two (2) years of his or her employment with

the Company, came into contact for the purpose of soliciting or servicing business or about whom the Employee obtained confidential information to leave employment with the Company.

5.Enforcement

(a)    The Executive acknowledges and agrees that the covenants contained in this Agreement are reasonable and necessary to protect the confidential information and goodwill of the Company and its subsidiaries. The Executive further represents that his experience and capabilities are such that the provisions of this Agreement will not prevent him from earning a livelihood.

(b)    The Executive acknowledges and agrees that compliance with the covenants set forth in this Agreement is necessary to protect the Confidential Information and Trade Secrets, business and goodwill of the Company, and that any breach of this Agreement will result in irreparable and continuing harm to the Company, for which money damages may not provide adequate relief. Accordingly, in the event of any breach or anticipatory breach of this Agreement by the Executive, or the Executive’s claim in a declaratory judgment action that all or part of this Agreement is unenforceable, the parties agree that the Company shall be entitled to the following particular forms of relief as a result of such breach, in addition to any remedies otherwise available to it at law or equity: (a) injunctions, both preliminary and permanent, enjoining or restraining such breach or anticipatory breach, and the Executive hereby consents to the issuance thereof forthwith and without bond by any court of competent jurisdiction; and (b) recovery of all reasonable sums and costs, including attorneys’ fees, incurred by the Company to defend or enforce the provisions of this Agreement.

(c)    In the event the Company is required to enforce any of its rights hereunder through legal proceedings, the parties acknowledge that it may be difficult or impossible to ascertain the precise amount of damages or lost profits incurred by the Company. Therefore, in the event of any breach by Executive of Section 3 of this Agreement, in addition to any other relief available to the Company at law or in equity, Executive agrees that the damages for each client lost in whole or in part by the Company as a result of my breach shall be 200% of the gross commissions and fees received by the Company from such client during the twelve (12) months preceding the cessation of my employment. In arriving at this calculation, Executive agrees that the Company and Executive have considered the following factors: (i) the value of the clients; (ii) the business of the Company; (iii) the type and quality of the clients; (iv) the substantial amount of time, effort and expense incurred by the Company in acquiring, developing and maintaining the clients; (v) the number of years the Company typically retains such clients; (vi) the profitability of renewal business; and (vii) various other factors relating to the relationship between the Company and the clients. Executive further agrees that Executive shall be obligated to reimburse the Company for all reasonable costs, expenses and counsel fees incurred by the Company in connection with the enforcement of its rights hereunder.

(d)    The restrictive periods set forth in this Agreement (including those set forth in Sections 2, 3 and 4 hereof) shall not expire and shall be tolled during any period in which the Executive is in violation of such restrictive periods, and therefore such restrictive periods shall be extended for a periods equal to the durations of the Executive’s violations thereof.

6.Employment At-Will

The Executive understands that this Agreement does not constitute a contract of employment and does not promise or imply that his or her employment will continue for any period of time. Unless otherwise agreed to under any separate employment contract between the Executive and the Company whether executed prior to this Agreement or at any time hereafter,

employment with the Company is “at will” and may be terminated either by the Executive or the Company at any time, with or without cause, and with or without notice.

7.Miscellaneous

(a)    Governing Law; Choice of Forum. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to its conflict of laws provisions. The parties being desirous of having any disputes resolved in a forum having a substantial body of law and experience with the matters contained herein, the parties agree that any action or proceeding with respect to this Agreement and Executive’s employment shall be brought exclusively in the Supreme Court of the State of New York, New York County, or in the United States District Court for the Southern District of New York, and the parties agree to the personal jurisdiction thereof. The parties hereby irrevocably waive any objection they may now or hereafter have to the laying of venue of any such action in the said court(s), and further irrevocably waive any claim they may now or hereafter have that any such action brought in said court(s) has been brought in an inconvenient forum. Executive recognizes that, should any dispute or controversy arising from or relating to this agreement be submitted for adjudication to any court, arbitration panel or other third party, the preservation of the secrecy of confidential information or trade secrets may be jeopardized. Consequently, Executive agrees that all issues of fact shall be severed for trial without a jury.

(b)    Severability. The parties agree they have attempted to limit the scope of the post-employment restrictions contained herein to the extent necessary to protect Confidential Information and Trade Secrets, client relationships and goodwill. It is the desire and intent of the parties that the provisions of this Agreement shall be enforced to the fullest extent permissible under applicable laws and public policies. Accordingly, if any particular portion of this Agreement shall be adjudicated to be invalid or unenforceable, this Agreement shall be deemed amended to delete therefrom such invalid portion, and reformed to the extent valid and enforceable. Such deletion and reformation shall apply only with respect to the operation of this Agreement in the particular jurisdiction in which such adjudication is made.

(c)    Modification. No modification of this Agreement shall be valid unless made in a writing signed by both parties hereto, wherein specific reference is made to this Agreement.

(d)    Non-Waiver. The failure of either the Company or the Executive, whether purposeful or otherwise, to exercise in any instance any right, power, or privilege under this Agreement or under law shall not constitute a waiver of the same or any other right, power, or privilege in any other instance. Any waiver by the Company or by the Executive must be in writing and signed by either the Executive, if the Executive is seeking to waive any of his or her rights under this Agreement, or by the Chief Executive Officer of the Company, if the Company is seeking to waive any of its rights under this Agreement.

(e)    Binding Effect. This Agreement shall be binding upon the Executive, the Executive’s heirs, executors and administrators, and upon the Company, and its successors and assigns, and shall inure to the benefit of the Company, and its successors and assigns. This Agreement may not be assigned by the Executive. This Agreement may be enforced by the Company’s successors and assigns

(f)    Other Agreements Survive. The obligations of the Executive under this Agreement shall be independent of, and unaffected by, and shall not affect, other agreements, if any, binding the Executive which apply to the Executive’s business activities during and/or subsequent to the Executive’s employment by the Company. The obligations under this Agreement also shall survive any changes made in the future to the employment terms of Executive, including but not limited to changes in salary, benefits, bonus plans, job title and job responsibilities.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and year first hereinabove set forth.

3. Conflict Of Interest

A direct or indirect financial interest, including joint ventures in or with a supplier, vendor, customer or prospective customer without disclosure and the express written approval of the President or highest executive officer of Company is strictly prohibited and constitutes cause for dismissal.

4. Equitable Relief

In recognition of the fact that irreparable injury will result to the Company in the event of a breach by the Employee of his/her obligations under this Agreement, that monetary damages for such breach would not be readily calculable, and that the Company would not have an adequate remedy at law therefor, the Employee acknowledges, consents and agrees that in the event of such breach, or the threat thereof, the Company shall be entitled, in addition to any other legal remedies and damages available, to (a) specific performance thereof and to temporary and permanent injunctive relief (without the necessity of posting a bond) to restrain the violation or threatened violation of such obligations by the Employee and persons acting for or in connection with the Employee and (b) recovery of all reasonable sums and costs, including attorneys' fees, incurred by the Company in seeking to enforce the provisions of this Agreement.

Such deletion

2

and reformation shall apply only with respect to the operation of this Agreement in the particular jurisdiction in which such adjudication is made.

6. Other Agreements Survive

The obligations of the Employee under this Agreement shall be independent of, and unaffected by, and shall not affect, other agreements, if any, binding the Employee which apply to the Employee's business activities during and/or subsequent to the Employee's employment by the Company.

7. Employment At-Will

The Employee understands that this Agreement does not constitute a contract of employment and does not promise or imply that his/her employment will continue for any period of time.

8. Binding Effect; Assignment

The Employee expressly consents to be bound by the provisions of this Agreement for the benefit of the Company or any of its subsidiaries or affiliates to whose employ he/she may be transferred without the necessity that this Agreement be re-signed at the time of such transfer.

9. Governing Law and Choice of Forum

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to its conflict of laws provisions.

The parties hereby irrevocably waive any objection they may now or hereafter have to the laying of venue of any such action in the said court(s), and further irrevocably waive any claim they may now or hereafter have that any such action brought in said court(s) has been brought in an inconvenient forum. Employee recognizes that, should any dispute or controversy arising from or relating to this agreement be submitted for adjudication to any court, arbitration panel or other third party, the preservation of the secrecy of Confidential Information or Trade Secrets may be jeopardized.

10. Non-Waiver

c.Equitable Relief. In recognition of the fact that irreparable injury will result to the Company in the event of a breach of my obligations under this Agreement, that monetary damages for such breach would not be readily calculable, and that the Company would not have an adequate remedy at law therefore, I acknowledge, consent and agree that in the event of such breach, or the threat thereof, the Company shall be entitled, in addition to any other legal remedies and damages available, to (a) specific performance thereof and to temporary and permanent injunctive relief (without the necessity of posting a bond) to restrain the violation or threatened violation of such obligations by me and persons acting for or in connection with me, and (b) recovery of all reasonable sums and costs, including attorneys' fees, incurred by the Company in seeking to enforce the provisions of this Agreement.

d.Severability. The parties agree they have attempted to limit the scope of the post-employment restrictions contained herein to the extent necessary to protect the Company's Confidential Information and Trade Secrets, client relationships and good will. It is the desire and intent of the parties that the provisions of this Agreement shall be enforced to the fullest extent permissible under applicable laws and public policies. I agree that the provisions of this Agreement shall be enforced to the fullest extent permissible under applicable laws and public policies. Accordingly, if any particular portion of this Agreement shall be adjudicated to be invalid or unenforceable, this Agreement shall be deemed amended to delete therefrom such invalid portion, and reformed to the extent necessary to make it valid and enforceable. Such amendment and

3

reformation shall apply only with respect to the operation of this Agreement in the particular jurisdiction in which such adjudication is made.

e.Other Agreements Survive. I understand that my obligations under this Agreement shall be independent of and in addition to other agreements, if any, binding me which relate to confidentiality or my business activities during and/or subsequent to my employment by the Company.

f.Employment At-Will. I understand that this Agreement does not constitute a contract of employment and does not promise or imply that my employment will continue for any period of time. Employment with Company is “at-will,” and may be terminated either by me or the Company at any time, with or without cause, and with or without notice.

g.Binding Effect; Assignment. I expressly consent to be bound by the provisions of this Agreement for the benefit of the Company or any subsidiary or affiliate thereof to whose employ I may be transferred without the necessity that this Agreement be re-executed at the time of such transfer. Further, the rights of the Company hereunder may be assigned, without my consent, at any time, to any successor in interest of the Company, or any portion thereof, by reason of merger, consolidation, sale, lease or other disposition of any or all of the assets or stock of the Company.

h.Governing Law; Choice of Forum. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York applicable to agreements made and to be performed herein, without regard to its conflict of laws provisions. The parties being desirous of having any disputes resolved in a forum having a substantial body of law and experience with the matters contained herein, the parties agree that any action or proceeding with respect to this Agreement and my employment shall be brought exclusively in the Supreme Court of the State of New York, New York County, or in the United States District Court for the Southern District of New York and the parties agree to the jurisdiction thereof. The parties hereby irrevocably waive any objection they may now or hereafter have to the laying of venue of any such action in the said court(s), and further irrevocably waive any claim they may now or hereafter have that any such action brought in said court(s) has been brought in an inconvenient forum. I recognize that, should any dispute or controversy arising from or relating to this agreement be submitted for adjudication to any court, arbitration panel or other third party, the preservation of the secrecy of Confidential Information or Trade Secrets may be jeopardized. Consequently, I agree that all issues of fact shall be severed for trial without a jury.

i.Non-Waiver. The failure of either the Company or me, whether purposeful or otherwise, to exercise in any instance any right, power, or privilege under this Agreement or under law shall not constitute a waiver of any other right, power, or privilege, nor of the same right, power, or privilege in any other instance. Any waiver by the Company or by me must be in writing and signed by either me, if I am seeking to waive any of my rights under this Agreement, or by the CEO or highest executive officer of the Company, if the Company is seeking to waive any of its rights under this Agreement.

j.Modification. No modification of this Agreement shall be valid unless made in a writing signed by both parties hereto, wherein specific reference is made to this Agreement.

Exhibit 10.69

NON-COMPETITION AND NON-SOLICITATION AGREEMENT

AGREEMENT, dated as of April 20, 2011, between Marsh Inc. and/or subsidiaries thereof (the “Employer”), the parents and affiliates of which comprise Marsh & McLennan Companies, Inc. (the “Company”), and Peter Zaffino, an employee of the Employer (the “Executive”).

RECITALS:

This Agreement is entered into in consideration of the (a) Executive’s employment by the Employer in a senior executive position, (b) Executive’s eligibility for certain bonus compensation of Employer, and (c) Executive’s access to confidential information and trade secrets belonging to Employer.

NOW, THEREFORE, the Employer and the Executive hereby agree to be bound by this Non-Competition and Non-Solicitation Agreement, as follows:

1.Confidential Information and Trade Secrets

(a)Executive understands and acknowledges that as an executive of the Company, Executive will learn or have access to, or may assist in the development of, highly confidential and sensitive information and trade secrets about the Company, its operations and its clients, and that providing its clients with appropriate assurances that their confidences will be protected is crucial to the Company’s ability to obtain clients, maintain good client relations, and conform to contractual obligations. Such Confidential Information and Trade Secrets include but are not limited to: (i) financial and business information relating to the Company, such as information with respect to costs, commissions, fees, profits, sales, markets, mailing lists, strategies and plans for future business, new business, product or other development, potential acquisitions or divestitures, and new marketing ideas; (ii) product and technical information relating to the Company, such as product formulations, new and innovative product ideas, methods, procedures, devices, machines, equipment, data processing programs, software, software codes, computer models, and research and development projects; (iii) client information, such as the identity of the Company’s clients, the names of representatives of the Company’s clients responsible for entering into contracts with the Company, the amounts paid by such clients to the Company, specific client needs and requirements, specific client risk characteristics, policy expiration dates, policy terms and conditions, information regarding the markets or sources with which insurance is placed, and leads and referrals to prospective clients; (iv) personnel information, such as the identity and number of the Company’s other employees, their salaries, bonuses, benefits, skills, qualifications, and abilities; (v) any and all information in whatever form relating to any client or prospective client of the Company, including but not limited to, its business, employees, operations, systems, assets, liabilities, finances, products, and marketing, selling and operating practices; (vi) any information not included in (i) or (ii) above which Executive knows or should know is subject to a restriction on disclosure or which Executive knows or should know is considered by the Company or the Company's clients or prospective clients to be confidential, sensitive, proprietary or a trade secret or is not readily available to the public; and (vii) intellectual property, including inventions and copyrightable works. Confidential Information and Trade Secrets are not generally known or available to the general public, but have been developed, compiled or acquired by the Company

at its great effort and expense. Confidential Information and Trade Secrets can be in any form: oral, written or machine readable, including electronic files.

(b)Executive acknowledges and agrees that the Company is engaged in a highly competitive business and that its competitive position depends upon its ability to maintain the confidentiality of the Confidential Information and Trade Secrets which were developed, compiled and acquired by the Company at its great effort and expense. Executive further acknowledges and agrees that any disclosing, divulging, revealing, or using of any of the Confidential Information and Trade Secrets, other than in connection with the Company’s business or as specifically authorized by the Company, will be highly detrimental to the Company and cause it to suffer serious loss of business and pecuniary damage.

(c)At all times prior to and following the Executive’s termination of employment, the Executive shall not disclose to anyone or make use of any trade secret or proprietary or confidential information of the Company or any subsidiary, including such trade secret or proprietary or confidential information of any customer or client or other entity to which the Company or any subsidiary owes an obligation not to disclose such information, which the Executive acquires during the Executive’s employment with the Company or any subsidiary, including but not limited to records kept in the ordinary course of business except: (i) as such disclosure or use may be required or appropriate in connection with the Executive’s work as an employee of the Company or any subsidiary; (ii) when required to do so by a court of law, by any governmental agency having supervisory authority over the business of the Company or any subsidiary or by any administrative or legislative body (including a committee thereof) with apparent jurisdiction to order the Executive to divulge, disclose or make accessible such information; or (iii) as to such confidential information that becomes generally known to the public or trade without the Executive’s violation of this Agreement.

(d)Immediately upon the termination of employment with the Company for any reason, or at any time the Company so requests, Executive will return to the Company: (i) any originals and all copies of all files, notes, documents, slides (including transparencies), computer disks, printouts, reports, lists of the Company’s clients or leads or referrals to prospective clients, and other media or property in Executive’s possession or control which contain or pertain to Confidential Information or Trade Secrets; and (ii) all property of the Company, including but not limited to supplies, keys, access devices, books, identification cards, computers, telephones and other equipment. Executive agrees that upon completion of the obligations set forth in this subparagraph and if requested by the Company, Executive will execute a statement in a form provided by the Company declaring that he or she has retained no property of the Company or materials containing Confidential Information nor has he or she supplied the same to any person, except as required to carry out his or her duties as an executive of the Company.

2.Non-Competition

(a)    Executive acknowledges and agrees that the Company is engaged in a highly competitive business and that by virtue of Executive’s position and responsibilities with the Company and Executive’s access to the Confidential Information and Trade Secrets, engaging in any business which is directly competitive with the Company will cause it great and irreparable harm.

(b)    Accordingly, both during the Executive’s employment with the Company or any subsidiary and during the twelve (12) month period following the cessation of the Executive’s employment with the Company or any subsidiary, whether voluntarily or involuntarily and for any reason, the Executive shall not, without the express written consent of the Chief Executive Officer of the Company, directly or indirectly own, manage, operate or control, or be employed in a capacity

similar to the position(s) held by Executive with the Company by any company or entity engaged in such segment(s) of the Company’s Business for which Executive had responsibility or about which Employee had knowledge of or access to Confidential Information and Trade Secrets while employed by the Company. For purposes of this Agreement, the Company’s “Business” means the provision of insurance brokerage and risk management services of the type provided by the Company and its subsidiaries and affiliates. In recognition of the international nature of the Company’s Business which includes the sale of its products and services globally, this restriction shall apply in all countries throughout the world where the Company does business as of the date of termination of the Executive’s employment with the Company. It is specifically agreed and understood that the Executive’s acceptance of employment with an insurance or reinsurance carrier following termination of Executive’s employment with the Company is not prohibited by this Agreement.

3.Non-Solicitation of Clients

(a)The Executive acknowledges and agrees that solely by reason of employment by the Company, the Executive has and will come into contact with a significant number of the Company’s clients and prospective clients and have access to Confidential Information and Trade Secrets relating thereto, including those regarding the Company’s clients, prospective clients and related information.

(b)    Consequently, during the twelve (12) month period following the cessation of the Executive’s employment with the Company or any subsidiary, whether voluntarily or involuntarily and for any reason, the Executive shall not, without the express written consent of the Chief Executive Officer of the Company, directly or indirectly: (i) solicit clients of the Company for the purpose of selling or providing products or services of the type sold or provided by the Executive while employed by the Company; or (ii) induce clients or prospective clients of the Company to terminate, cancel, not renew, or not place business with the Company; or (iii) perform or supervise the performance of services or provision of products of the type sold or provided by the Executive while he or she was employed by the Company on behalf of any clients or prospective clients of the Company. This restriction shall apply only to those clients or prospective clients of the Company with whom the Executive had contact or about whom the Executive obtained Confidential Information or Trade Secrets during the last two (2) years of his or her employment with the Company. For the purposes of this Section, the term “contact” means interaction between the Executive and the client which takes place to further the business relationship, or making (or assisting or supervising the making of) sales to or performing or providing (or assisting or supervising the performance or provision of) services or products for the client on behalf of the Company. For purposes of this Section 2, the term “contact” with respect to a “prospective” client means interaction between the Executive and a potential client of the Company which takes place to obtain the business of the potential client on behalf of the Company.

4.Non-Solicitation of Employees

The Executive acknowledges and agrees that solely as a result of employment with the Company, and in light of the broad responsibilities of such employment which include working with other employees of the Company, the Executive has and will come into contact with and acquire confidential information and trade secrets regarding the Company’s other employees. Accordingly, during the Executive’s employment with the Company or any subsidiary and during the twelve (12) month period following the cessation of the Executive’s employment with the Company or any subsidiary, whether voluntarily or involuntarily and for any reason, the Executive shall not, without the express written consent of the Chief Executive Officer of the Company the Executive shall not, either on the Executive’s own account or on behalf of any person, company, corporation, or other entity, directly or indirectly, solicit, or endeavor to cause any employee of the Company with whom the Executive, during the last two (2) years of his or her employment with

the Company, came into contact for the purpose of soliciting or servicing business or about whom the Employee obtained confidential information to leave employment with the Company.

5.Enforcement

(a)    The Executive acknowledges and agrees that the covenants contained in this Agreement are reasonable and necessary to protect the confidential information and goodwill of the Company and its subsidiaries. The Executive further represents that his experience and capabilities are such that the provisions of this Agreement will not prevent him from earning a livelihood.

(b)    The Executive acknowledges and agrees that compliance with the covenants set forth in this Agreement is necessary to protect the Confidential Information and Trade Secrets, business and goodwill of the Company, and that any breach of this Agreement will result in irreparable and continuing harm to the Company, for which money damages may not provide adequate relief. Accordingly, in the event of any breach or anticipatory breach of this Agreement by the Executive, or the Executive’s claim in a declaratory judgment action that all or part of this Agreement is unenforceable, the parties agree that the Company shall be entitled to the following particular forms of relief as a result of such breach, in addition to any remedies otherwise available to it at law or equity: (a) injunctions, both preliminary and permanent, enjoining or restraining such breach or anticipatory breach, and the Executive hereby consents to the issuance thereof forthwith and without bond by any court of competent jurisdiction; and (b) recovery of all reasonable sums and costs, including attorneys’ fees, incurred by the Company to defend or enforce the provisions of this Agreement.

(c)    In the event the Company is required to enforce any of its rights hereunder through legal proceedings, the parties acknowledge that it may be difficult or impossible to ascertain the precise amount of damages or lost profits incurred by the Company. Therefore, in the event of any breach by Executive of Section 3 of this Agreement, in addition to any other relief available to the Company at law or in equity, Executive agrees that the damages for each client lost in whole or in part by the Company as a result of my breach shall be 200% of the gross commissions and fees received by the Company from such client during the twelve (12) months preceding the cessation of my employment. In arriving at this calculation, Executive agrees that the Company and Executive have considered the following factors: (i) the value of the clients; (ii) the business of the Company; (iii) the type and quality of the clients; (iv) the substantial amount of time, effort and expense incurred by the Company in acquiring, developing and maintaining the clients; (v) the number of years the Company typically retains such clients; (vi) the profitability of renewal business; and (vii) various other factors relating to the relationship between the Company and the clients. Executive further agrees that Executive shall be obligated to reimburse the Company for all reasonable costs, expenses and counsel fees incurred by the Company in connection with the enforcement of its rights hereunder.

(d)    The restrictive periods set forth in this Agreement (including those set forth in Sections 2, 3 and 4 hereof) shall not expire and shall be tolled during any period in which the Executive is in violation of such restrictive periods, and therefore such restrictive periods shall be extended for a periods equal to the durations of the Executive’s violations thereof.

6.Employment At-Will

The Executive understands that this Agreement does not constitute a contract of employment and does not promise or imply that his or her employment will continue for any period of time. Unless otherwise agreed to under any separate employment contract between the Executive and the Company whether executed prior to this Agreement or at any time hereafter,

employment with the Company is “at will” and may be terminated either by the Executive or the Company at any time, with or without cause, and with or without notice.

7.Miscellaneous

(a)    Governing Law; Choice of Forum. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to its conflict of laws provisions. The parties being desirous of having any disputes resolved in a forum having a substantial body of law and experience with the matters contained herein, the parties agree that any action or proceeding with respect to this Agreement and Executive’s employment shall be brought exclusively in the Supreme Court of the State of New York, New York County, or in the United States District Court for the Southern District of New York, and the parties agree to the personal jurisdiction thereof. The parties hereby irrevocably waive any objection they may now or hereafter have to the laying of venue of any such action in the said court(s), and further irrevocably waive any claim they may now or hereafter have that any such action brought in said court(s) has been brought in an inconvenient forum. Executive recognizes that, should any dispute or controversy arising from or relating to this agreement be submitted for adjudication to any court, arbitration panel or other third party, the preservation of the secrecy of confidential information or trade secrets may be jeopardized. Consequently, Executive agrees that all issues of fact shall be severed for trial without a jury.

(b)    Severability. The parties agree they have attempted to limit the scope of the post-employment restrictions contained herein to the extent necessary to protect Confidential Information and Trade Secrets, client relationships and goodwill. It is the desire and intent of the parties that the provisions of this Agreement shall be enforced to the fullest extent permissible under applicable laws and public policies. Accordingly, if any particular portion of this Agreement shall be adjudicated to be invalid or unenforceable, this Agreement shall be deemed amended to delete therefrom such invalid portion, and reformed to the extent valid and enforceable. Such deletion and reformation shall apply only with respect to the operation of this Agreement in the particular jurisdiction in which such adjudication is made.

(c)    Modification. No modification of this Agreement shall be valid unless made in a writing signed by both parties hereto, wherein specific reference is made to this Agreement.

(d)    Non-Waiver. The failure of either the Company or the Executive, whether purposeful or otherwise, to exercise in any instance any right, power, or privilege under this Agreement or under law shall not constitute a waiver of the same or any other right, power, or privilege in any other instance. Any waiver by the Company or by the Executive must be in writing and signed by either the Executive, if the Executive is seeking to waive any of his or her rights under this Agreement, or by the Chief Executive Officer of the Company, if the Company is seeking to waive any of its rights under this Agreement.

(e)    Binding Effect. This Agreement shall be binding upon the Executive, the Executive’s heirs, executors and administrators, and upon the Company, and its successors and assigns, and shall inure to the benefit of the Company, and its successors and assigns. This Agreement may not be assigned by the Executive. This Agreement may be enforced by the Company’s successors and assigns

(f)    Other Agreements Survive. The obligations of the Executive under this Agreement shall be independent of, and unaffected by, and shall not affect, other agreements, if any, binding the Executive which apply to the Executive’s business activities during and/or subsequent to the Executive’s employment by the Company. The obligations under this Agreement also shall survive any changes made in the future to the employment terms of Executive, including but not limited to changes in salary, benefits, bonus plans, job title and job responsibilities.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and year first hereinabove set forth.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2012

Accounting Policies [Abstract]

Nature of Operations

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 organizational structure, the Company’s two business segments are Risk and Insurance Services and Consulting.

The Risk and Insurance Services segment provides risk management and insurance broking, reinsurance broking and insurance program management services for businesses, public entities, insurance companies, associations, professional services organizations, and private clients. The Company conducts business in this segment through Marsh and Guy Carpenter.

The Company conducts business in its Consulting segment through two main business groups. Mercer provides consulting expertise, advice, services and solutions in the areas of talent, health, retirement and investments. Oliver Wyman Group provides specialized management and economic and brand consulting services.

Acquisitions impacting the Risk and Insurance Services and Consulting segments are discussed in Note 4 to the consolidated financial statements.

On August 3, 2010, the Company completed the sale of Kroll, the Company’s former Risk Consulting & Technology segment, to Altegrity, Inc. (“Altegrity”) for cash consideration of $1.13 billion. In the first quarter of 2010, Kroll completed the sale of Kroll Laboratory Specialists (“KLS”). The gain on the sale of Kroll and related tax benefits and the after-tax loss on the sale of KLS, along with Kroll’s, and KLS’s 2010 results of operations are included in discontinued operations in 2010.

With the sale of Kroll in August 2010, along with other dispositions between 2008 and 2010, the Company has divested its entire Risk Consulting and Technology Segment. The Company has “continuing involvement” in certain Corporate Advisory and Restructuring businesses (“CARG”) that were disposed of in 2008. The runoff of the CARG businesses is being managed by the Company's corporate departments and financial results of these entities are included in “Corporate” for segment reporting purposes.

Principles of Consolidation

Principles of Consolidation:  The accompanying consolidated financial statements include all wholly-owned and majority-owned subsidiaries. All significant inter-company transactions and balances have been eliminated.

Fiduciary Assets And Liabilities

Fiduciary Assets and Liabilities:  In its capacity as an insurance broker or agent, the Company generally collects premiums from insureds and, after deducting its commissions, remits the premiums to the respective insurance underwriters. The Company also collects claims or refunds from underwriters on behalf of insureds. Unremitted insurance premiums and claims proceeds are held by the Company in a fiduciary capacity. Risk and Insurance Services revenue includes interest on fiduciary funds of $39 million, $47 million and $45 million in 2012, 2011 and 2010, respectively. The Consulting segment recorded fiduciary interest income of $4 million in each of 2012 , 2011 and 2010. Since fiduciary assets are not available for corporate use, they are shown in the consolidated balance sheets as an offset to fiduciary liabilities.

Net uncollected premiums and claims and the related payables amounted to $9.1 billion and $9 billion at December 31, 2012 and 2011, 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. Net uncollected premiums and claims and the related payables are, therefore, not assets and liabilities of the Company and are not included in the accompanying consolidated balance sheets.

In certain instances, the Company advances premiums, refunds or claims to insurance underwriters or insureds prior to collection. These advances are made from corporate funds and are reflected in the accompanying consolidated balance sheets as receivables.

Mercer manages approximately $16 billion of assets in trusts or funds for which Mercer’s management or trustee fee is considered a variable interest. Mercer is not the primary beneficiary of these trusts or funds. Mercer’s only variable interest in any of these trusts or funds is its unpaid fees, if any. Mercer’s maximum exposure to loss of its interests is, therefore, limited to collection of its fees.

Revenue

Revenue:  Risk and Insurance Services revenue includes insurance commissions, fees for services rendered and interest income on certain fiduciary funds. Insurance commissions and fees for risk transfer services generally are recorded as of the effective date of the applicable policies or, in certain cases (primarily in the Company's reinsurance broking operations), as of the effective date or billing date, whichever is later. A reserve for policy cancellation is provided based on historic and current data on cancellations. Fees for non-risk transfer services provided to clients are recognized over the period in which the services are provided, using a proportional performance model. Fees resulting from achievement of certain performance thresholds are recorded when such levels are attained and such fees are not subject to forfeiture.

As part of the sale of MMC Capital in 2005, the Company retained the right to receive certain performance fees related to the Trident II and Trident III private equity partnerships. The Company recognizes performance fee income when such fees are no longer subject to forfeiture, which may take a number of years to resolve. The Company has deferred the recognition of income related to such performance fees of $78 million and $74 million at December 31, 2012 and 2011, respectively. This income is based on the investment performance over the life of each private equity fund, and future declines in fund performance from current levels may result in the forfeiture of such revenue. In the first quarter of 2013, Trident II sold substantially all of the remaining assets of the fund and the fund will wind down. As a result, approximately $15 million of the deferred performance fees will be recognized as part of investment income.

Consulting revenue includes fees paid by clients for advice and services and commissions from insurance companies for the placement of individual and group contracts. Fee revenue for engagements where remuneration is based on time plus out-of-pocket expenses is recognized based on the amount of time consulting professionals expend on the engagement. For fixed fee engagements, revenue is recognized using a proportional performance model. Revenue from insurance commissions not subject to a fee arrangement is recorded over the effective period of the applicable policies. Revenues for asset based fees are recognized on an accrual basis by applying the daily/monthly rate as contractually agreed with the client to the applicable net asset value. On a limited number of engagements, performance fees may also be earned for achieving certain pre-determined performance criteria. Such fees are recognized when the performance criteria have been achieved and agreed to by the client. Expenses incurred by professional staff in the generation of revenue are billed to the client and included in revenue.

Cash and Cash Equivalents

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.

Fixed Assets

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

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

Investment Securities

Investment Securities:  The Company holds investments primarily in private companies and certain private equity funds.

Certain investments, primarily investments in private equity funds, are accounted for under the equity method 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 securities within the fund are carried at fair value. The Company records its proportionate share of the change in fair value of the funds in earnings which amounted to gains of $33 million, $10 million and $32 million in 2012, 2011 and 2010, respectively. Securities recorded using the equity method are included in other assets in the consolidated balance sheets.

The Company has an investment in Trident II limited partnership, a private equity investment fund. At December 31, 2012, the Company’s investment in Trident II was approximately $78 million, reflected in other assets in the consolidated balance sheet. In the first quarter of 2013, Trident II sold substantially all remaining assets and the fund will wind down. The Company expects to receive approximately $100 million in cash proceeds related to this sale in 2013.

Gains or losses recognized in earnings from the investment securities, including the performance fees discussed above, are included in investment income in the consolidated statements of income. Costs related to management of the Company’s investments, including incentive compensation partially derived from investment income and (loss), are recorded in operating expenses.

Goodwill and Intangible Assets

Goodwill and Other Intangible Assets:  Goodwill represents acquisition costs in excess of the fair value of net assets acquired. Goodwill is reviewed at least annually for impairment. The Company performs an annual impairment test for each of its reporting units during the third quarter of each year. When a step 1 test is performed, fair values of the reporting units are estimated using either a market approach or a discounted cash flow model. Carrying values for the reporting units are based on balances at the prior quarter end and include directly identified assets and liabilities as well as an allocation of those assets and liabilities not recorded at the reporting unit level. As discussed in Note 6, the Company assesses qualitative factors to determine if a step 1 assessment is necessary. Other intangible assets, which primarily consist of customer lists, that are not deemed to have an indefinite life are amortized over their estimated lives and reviewed for impairment upon the occurrence of certain triggering events in accordance with applicable accounting literature. The Company had no indefinite lived identified intangible assets at December 31, 2012 or 2011.

Capitalized Software Costs

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 three to ten 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 $278 million and $244 million, net of accumulated amortization of $691 million and $619 million at December 31, 2012 and 2011, respectively, are included in other assets in the consolidated balance sheets.

Legal and Other Loss Contingencies

Legal and Other Loss Contingencies:  The Company and its subsidiaries are subject to numerous claims, lawsuits and proceedings including claims for errors and omissions ("E&O"). GAAP requires that a liability be recorded when a loss is both probable and reasonably estimable. Significant management judgement is required to apply this guidance. The Company utilizes case level reviews by inside and outside counsel, an internal actuarial analysis and other analyses to estimate potential losses. The liability is reviewed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable. Given the unpredictability of E&O claims and of litigation that could flow from them, it is possible that an adverse outcome in a particular matter could have a material adverse effect on the Company’s businesses, results of operations, financial condition or cash flow in a given quarterly or annual period.

In addition, to the extent that insurance coverage is available, significant management judgment is required to determine the amount of recoveries that are probable of collection under the Company’s various insurance programs.

The legal and other contingent liabilities described above are not discounted.

Income Taxes

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 effective tax rate 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 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. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition, and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Tax law requires items be included in the Company's tax returns at different times than the items are reflected in the financial statements. As a result, the annual tax expense reflected in the consolidated statements of income is different than that reported in the income tax returns. Some of these differences are permanent, such as expenses that are not deductible in the returns, and some differences are temporary and reverse over time, such as depreciation expense. Temporary differences create deferred tax assets and liabilities. Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns in future years for which benefit has already been recorded in the financial statements. Valuation allowances are established for deferred tax assets when it is estimated that future taxable income will be insufficient to use a deduction or credit in that jurisdiction. Deferred tax liabilities generally represent tax expense recognized in the financial statements for which payment has been deferred, or expense for which a deduction has been taken already in the tax return but the expense has not yet been recognized in the financial statements.

Derivative Instruments

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. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive income and are recognized in the income statement when the hedged item affects earnings. Changes in the fair value attributable to the ineffective portion of cash flow hedges are recognized in earnings.

Concentrations Of Credit Risk

Concentrations of Credit Risk:  Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, commissions and fees receivable and insurance recoverables. The Company maintains a policy providing for the diversification of cash and cash equivalent investments and places its investments in a large number of high quality financial institutions to limit the amount of credit risk exposure. Concentrations of credit risk with respect to receivables are generally limited due to the large number of clients and markets in which the Company does business, as well as the dispersion across many geographic areas.

Per Share Data

Per Share Data: Under the accounting guidance which applies to the calculation of earnings per share (“EPS”) for share-based payment awards with rights to dividends or dividend equivalents, unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and should be included in the computation of basic and dilutive EPS using the two-class method.

Basic net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income attributable to common shares by the weighted average number of outstanding shares of the Company’s common stock.

Diluted net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income attributable to common shares by the weighted average number of outstanding shares of the Company’s common stock, which have been adjusted for the dilutive effect of potentially issuable common shares (excluding those that are considered participating securities). The diluted earnings per share calculation reflects the more dilutive effect of either (a) the two-class method that assumes that the participating securities have not been exercised or (b) the treasury stock method. Reconciliation of the applicable income components used for diluted earnings per share and basic weighted average common shares outstanding to diluted weighted average common shares outstanding is presented below.

Estimates

Estimates:  The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may vary from those estimates.

New Accounting Pronouncements

New Accounting Pronouncements:  In the first quarter of 2012, the Company adopted new accounting guidance related to the presentation of Comprehensive Income. The new guidance gives an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The guidance did not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income.

On February 5, 2013, the FASB issued new accounting guidance that adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. The Company is required to implement this new guidance for the reporting period ended March 31, 2013. Other than enhanced disclosure, the adoption of this new guidance is not expected to have a material effect on the Company's financial statements.

In January 2012, the Company adopted guidance issued by the FASB on accounting and disclosure requirements related to fair value measurements. The guidance expands the disclosures on Level 3 inputs by requiring quantitative disclosure of the unobservable inputs and assumptions, as well as description of the valuation processes, the sensitivity of the fair value to changes in unobservable inputs and the hierarchy classification, valuation techniques, and inputs for assets and liabilities whose fair value is only disclosed in the footnotes.

In January 2011, the Company adopted guidance issued by the FASB on revenue recognition regarding multiple-deliverable revenue arrangements. Other than enhanced disclosure, the adoption of this new guidance did not have a material effect on the Company's financial statements.

In January 2011, the Company adopted guidance issued by the FASB which establishes a revenue recognition model for contingent consideration that is payable upon the achievement of an uncertain future event, referred to as a milestone. The scope of this guidance is limited to research or development arrangements and requires an entity to record the milestone payment in its entirety in the period received if the milestone meets all the necessary criteria to be considered substantive. However, entities would not be precluded from making an accounting policy election to apply another appropriate accounting policy that results in the deferral of some portion of the arrangement consideration. The adoption of this new guidance did not have a material impact on the Company’s financial statements.

Reclassification

Reclassifications: Certain reclassifications have been made to prior period amounts to conform with current year presentation, in particular with regard to combining income taxes receivable with other receivables on the consolidated balance sheets.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

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 organizational structure, the Company’s two business segments are Risk and Insurance Services and Consulting.

The Risk and Insurance Services segment provides risk management and insurance broking, reinsurance broking and insurance program management services for businesses, public entities, insurance companies, associations, professional services organizations, and private clients. The Company conducts business in this segment through Marsh and Guy Carpenter.

The Company conducts business in its Consulting segment through two main business groups. Mercer provides consulting expertise, advice, services and solutions in the areas of talent, health, retirement and investments. Oliver Wyman Group provides specialized management and economic and brand consulting services.

Acquisitions impacting the Risk and Insurance Services and Consulting segments are discussed in Note 4 to the consolidated financial statements.

On August 3, 2010, the Company completed the sale of Kroll, the Company’s former Risk Consulting & Technology segment, to Altegrity, Inc. (“Altegrity”) for cash consideration of $1.13 billion. In the first quarter of 2010, Kroll completed the sale of Kroll Laboratory Specialists (“KLS”). The gain on the sale of Kroll and related tax benefits and the after-tax loss on the sale of KLS, along with Kroll’s, and KLS’s 2010 results of operations are included in discontinued operations in 2010.

With the sale of Kroll in August 2010, along with other dispositions between 2008 and 2010, the Company has divested its entire Risk Consulting and Technology Segment. The Company has “continuing involvement” in certain Corporate Advisory and Restructuring businesses (“CARG”) that were disposed of in 2008. The runoff of the CARG businesses is being managed by the Company's corporate departments and financial results of these entities are included in “Corporate” for segment reporting purposes.

Principles of Consolidation:  The accompanying consolidated financial statements include all wholly-owned and majority-owned subsidiaries. All significant inter-company transactions and balances have been eliminated.

Fiduciary Assets and Liabilities:  In its capacity as an insurance broker or agent, the Company generally collects premiums from insureds and, after deducting its commissions, remits the premiums to the respective insurance underwriters. The Company also collects claims or refunds from underwriters on behalf of insureds. Unremitted insurance premiums and claims proceeds are held by the Company in a fiduciary capacity. Risk and Insurance Services revenue includes interest on fiduciary funds of $39 million, $47 million and $45 million in 2012, 2011 and 2010, respectively. The Consulting segment recorded fiduciary interest income of $4 million in each of 2012 , 2011 and 2010. Since fiduciary assets are not available for corporate use, they are shown in the consolidated balance sheets as an offset to fiduciary liabilities.

Net uncollected premiums and claims and the related payables amounted to $9.1 billion and $9 billion at December 31, 2012 and 2011, 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. Net uncollected premiums and claims and the related payables are, therefore, not assets and liabilities of the Company and are not included in the accompanying consolidated balance sheets.

In certain instances, the Company advances premiums, refunds or claims to insurance underwriters or insureds prior to collection. These advances are made from corporate funds and are reflected in the accompanying consolidated balance sheets as receivables.

Mercer manages approximately $16 billion of assets in trusts or funds for which Mercer’s management or trustee fee is considered a variable interest. Mercer is not the primary beneficiary of these trusts or funds. Mercer’s only variable interest in any of these trusts or funds is its unpaid fees, if any. Mercer’s maximum exposure to loss of its interests is, therefore, limited to collection of its fees.

Revenue:  Risk and Insurance Services revenue includes insurance commissions, fees for services rendered and interest income on certain fiduciary funds. Insurance commissions and fees for risk transfer services generally are recorded as of the effective date of the applicable policies or, in certain cases (primarily in the Company's reinsurance broking operations), as of the effective date or billing date, whichever is later. A reserve for policy cancellation is provided based on historic and current data on cancellations. Fees for non-risk transfer services provided to clients are recognized over the period in which the services are provided, using a proportional performance model. Fees resulting from achievement of certain performance thresholds are recorded when such levels are attained and such fees are not subject to forfeiture.

As part of the sale of MMC Capital in 2005, the Company retained the right to receive certain performance fees related to the Trident II and Trident III private equity partnerships. The Company recognizes performance fee income when such fees are no longer subject to forfeiture, which may take a number of years to resolve. The Company has deferred the recognition of income related to such performance fees of $78 million and $74 million at December 31, 2012 and 2011, respectively. This income is based on the investment performance over the life of each private equity fund, and future declines in fund performance from current levels may result in the forfeiture of such revenue. In the first quarter of 2013, Trident II sold substantially all of the remaining assets of the fund and the fund will wind down. As a result, approximately $15 million of the deferred performance fees will be recognized as part of investment income.

Consulting revenue includes fees paid by clients for advice and services and commissions from insurance companies for the placement of individual and group contracts. Fee revenue for engagements where remuneration is based on time plus out-of-pocket expenses is recognized based on the amount of time consulting professionals expend on the engagement. For fixed fee engagements, revenue is recognized using a proportional performance model. Revenue from insurance commissions not subject to a fee arrangement is recorded over the effective period of the applicable policies. Revenues for asset based fees are recognized on an accrual basis by applying the daily/monthly rate as contractually agreed with the client to the applicable net asset value. On a limited number of engagements, performance fees may also be earned for achieving certain pre-determined performance criteria. Such fees are recognized when the performance criteria have been achieved and agreed to by the client. Expenses incurred by professional staff in the generation of revenue are billed to the client and included in 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 of approximately $250 million related to regulatory requirements outside the U.S. or as collateral under captive insurance arrangements.

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

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

The components of fixed assets are as follows:

December 31,
(In millions of dollars)	2012			2011
Furniture and equipment	$	1,168		$	1,101
Land and buildings	412			405
Leasehold and building improvements	811			767
	2,391			2,273
Less-accumulated depreciation and amortization	(1,582		)	(1,469		)
	$	809		$	804

Investment Securities:  The Company holds investments primarily in private companies and certain private equity funds.

Certain investments, primarily investments in private equity funds, are accounted for under the equity method 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 securities within the fund are carried at fair value. The Company records its proportionate share of the change in fair value of the funds in earnings which amounted to gains of $33 million, $10 million and $32 million in 2012, 2011 and 2010, respectively. Securities recorded using the equity method are included in other assets in the consolidated balance sheets.

The Company has an investment in Trident II limited partnership, a private equity investment fund. At December 31, 2012, the Company’s investment in Trident II was approximately $78 million, reflected in other assets in the consolidated balance sheet. In the first quarter of 2013, Trident II sold substantially all remaining assets and the fund will wind down. The Company expects to receive approximately $100 million in cash proceeds related to this sale in 2013.

Gains or losses recognized in earnings from the investment securities, including the performance fees discussed above, are included in investment income in the consolidated statements of income. Costs related to management of the Company’s investments, including incentive compensation partially derived from investment income and (loss), are recorded in operating expenses.

Goodwill and Other Intangible Assets:  Goodwill represents acquisition costs in excess of the fair value of net assets acquired. Goodwill is reviewed at least annually for impairment. The Company performs an annual impairment test for each of its reporting units during the third quarter of each year. When a step 1 test is performed, fair values of the reporting units are estimated using either a market approach or a discounted cash flow model. Carrying values for the reporting units are based on balances at the prior quarter end and include directly identified assets and liabilities as well as an allocation of those assets and liabilities not recorded at the reporting unit level. As discussed in Note 6, the Company assesses qualitative factors to determine if a step 1 assessment is necessary. Other intangible assets, which primarily consist of customer lists, that are not deemed to have an indefinite life are amortized over their estimated lives and reviewed for impairment upon the occurrence of certain triggering events in accordance with applicable accounting literature. The Company had no indefinite lived identified intangible assets at December 31, 2012 or 2011.

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 three to ten 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 $278 million and $244 million, net of accumulated amortization of $691 million and $619 million at December 31, 2012 and 2011, respectively, are included in other assets in the consolidated balance sheets.

Legal and Other Loss Contingencies:  The Company and its subsidiaries are subject to numerous claims, lawsuits and proceedings including claims for errors and omissions ("E&O"). GAAP requires that a liability be recorded when a loss is both probable and reasonably estimable. Significant management judgement is required to apply this guidance. The Company utilizes case level reviews by inside and outside counsel, an internal actuarial analysis and other analyses to estimate potential losses. The liability is reviewed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable. Given the unpredictability of E&O claims and of litigation that could flow from them, it is possible that an adverse outcome in a particular matter could have a material adverse effect on the Company’s businesses, results of operations, financial condition or cash flow in a given quarterly or annual period.

In addition, to the extent that insurance coverage is available, significant management judgment is required to determine the amount of recoveries that are probable of collection under the Company’s various insurance programs.

The legal and other contingent liabilities described above are not discounted.

Income Taxes:  The Company's effective tax rate reflects its income, statutory tax rates and tax planning in the various jurisdictions in which it operates. Significant judgment is required in determining the annual effective tax rate 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 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. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition, and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Tax law requires items be included in the Company's tax returns at different times than the items are reflected in the financial statements. As a result, the annual tax expense reflected in the consolidated statements of income is different than that reported in the income tax returns. Some of these differences are permanent, such as expenses that are not deductible in the returns, and some differences are temporary and reverse over time, such as depreciation expense. Temporary differences create deferred tax assets and liabilities. Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns in future years for which benefit has already been recorded in the financial statements. Valuation allowances are established for deferred tax assets when it is estimated that future taxable income will be insufficient to use a deduction or credit in that jurisdiction. Deferred tax liabilities generally represent tax expense recognized in the financial statements for which payment has been deferred, or expense for which a deduction has been taken already in the tax return but the expense has not yet been recognized in the financial statements.

Derivative Instruments:  All derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive income and are recognized in the income statement when the hedged item affects earnings. Changes in the fair value attributable to the ineffective portion of cash flow hedges are recognized in earnings.

Concentrations of Credit Risk:  Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, commissions and fees receivable and insurance recoverables. The Company maintains a policy providing for the diversification of cash and cash equivalent investments and places its investments in a large number of high quality financial institutions to limit the amount of credit risk exposure. Concentrations of credit risk with respect to receivables are generally limited due to the large number of clients and markets in which the Company does business, as well as the dispersion across many geographic areas.

Per Share Data: Under the accounting guidance which applies to the calculation of earnings per share (“EPS”) for share-based payment awards with rights to dividends or dividend equivalents, unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and should be included in the computation of basic and dilutive EPS using the two-class method.

Basic net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income attributable to common shares by the weighted average number of outstanding shares of the Company’s common stock.

Diluted net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income attributable to common shares by the weighted average number of outstanding shares of the Company’s common stock, which have been adjusted for the dilutive effect of potentially issuable common shares (excluding those that are considered participating securities). The diluted earnings per share calculation reflects the more dilutive effect of either (a) the two-class method that assumes that the participating securities have not been exercised or (b) the treasury stock method. Reconciliation of the applicable income components used for diluted earnings per share and basic weighted average common shares outstanding to diluted weighted average common shares outstanding is presented below.

There were 32.0 million, 38.9 million and 43.4 million stock options outstanding as of December 31, 2012, 2011 and 2010, respectively.

Other Significant Matters Impacting Results in Prior Periods: In June 2010, the Company settled a lawsuit brought by the Alaska Retirement Management Board (“ARMB”) against Mercer. Under the terms of the settlement agreement, Mercer paid $500 million, of which $100 million was covered by insurance, and recognized a charge of $400 million in the second quarter of 2010.

Estimates:  The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may vary from those estimates.

New Accounting Pronouncements:  In the first quarter of 2012, the Company adopted new accounting guidance related to the presentation of Comprehensive Income. The new guidance gives an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The guidance did not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income.

On February 5, 2013, the FASB issued new accounting guidance that adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. The Company is required to implement this new guidance for the reporting period ended March 31, 2013. Other than enhanced disclosure, the adoption of this new guidance is not expected to have a material effect on the Company's financial statements.

In January 2012, the Company adopted guidance issued by the FASB on accounting and disclosure requirements related to fair value measurements. The guidance expands the disclosures on Level 3 inputs by requiring quantitative disclosure of the unobservable inputs and assumptions, as well as description of the valuation processes, the sensitivity of the fair value to changes in unobservable inputs and the hierarchy classification, valuation techniques, and inputs for assets and liabilities whose fair value is only disclosed in the footnotes.

In January 2011, the Company adopted guidance issued by the FASB on revenue recognition regarding multiple-deliverable revenue arrangements. Other than enhanced disclosure, the adoption of this new guidance did not have a material effect on the Company's financial statements.

In January 2011, the Company adopted guidance issued by the FASB which establishes a revenue recognition model for contingent consideration that is payable upon the achievement of an uncertain future event, referred to as a milestone. The scope of this guidance is limited to research or development arrangements and requires an entity to record the milestone payment in its entirety in the period received if the milestone meets all the necessary criteria to be considered substantive. However, entities would not be precluded from making an accounting policy election to apply another appropriate accounting policy that results in the deferral of some portion of the arrangement consideration. The adoption of this new guidance did not have a material impact on the Company’s financial statements.

Reclassifications: Certain reclassifications have been made to prior period amounts to conform with current year presentation, in particular with regard to combining income taxes receivable with other receivables on the consolidated balance sheets.

Stock Benefit Plans [Abstract]

Stock Benefit Plans

Stock Benefit Plans

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

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

On May 19, 2011, the Marsh & McLennan Companies, Inc. 2011 Incentive and Stock Award Plan (the “2011 Plan”) was approved by the Company's stockholders. The 2011 Plan replaced the Company's two previous equity incentive plans (the 2000 Senior Executive Incentive and Stock Award Plan and the 2000 Employee Incentive and Stock Award Plan).

The types of awards permitted under the 2011 Plan include stock options, restricted stock and restricted stock units payable in Company common stock or cash, and other stock-based and performance-based awards. The Compensation Committee of the Board of Directors (the “Compensation Committee”) determines, at its discretion, which affiliates may participate in the 2011 Plan, which eligible employees will receive awards, the types of awards to be received, and the terms and conditions thereof. The right of an employee to receive an award may be subject to performance conditions as specified by the Compensation Committee. The 2011 Plan contains provisions which, in the event of a change in control of the Company, may accelerate the vesting of the awards. The 2011 Plan retains the remaining share authority of the two previous plans as of the date the 2011 Plan was approved by stockholders. Awards relating to not more than approximately 23.2 million shares of common stock, plus shares remaining unused under certain pre-existing plans, may be made over the life of the 2011 Plan.

Our current practice is to grant non-qualified stock options, restricted stock units and/or performance stock units on an annual basis to senior executives and a limited number of other employees as part of their total compensation. We also grant restricted stock units during the year to new hires or as retention awards for certain employees. We have not granted restricted stock since 2005.

Stock Options: Options granted under the 2011 Plan may be designated as either incentive stock options or non-qualified stock options. The Compensation Committee determines the terms and conditions of the option, including the time or times at which an option may be exercised, the methods by which such exercise price may be paid, and the form of such payment. Options are generally granted with an exercise price equal to the market value of the Company's common stock on the date of grant. These option awards generally vest 25% per annum and have a contractual term of 10 years. Certain stock options granted under the previous equity incentive plans provided for a market-based triggering event before a vested option can be exercised. The terms and conditions of these stock option awards provided that (i) options will vest at a rate of 25% a year beginning one year from the date of grant and (ii) each vested tranche will only become exercisable if the market price of the Company stock appreciates to a level of 15% above the exercise price of the option and maintains that level for at least ten (10) consecutive trading days after the award has vested. The Company accounts for these awards as market-condition options. The effect of the market condition is reflected in the grant-date fair value of such awards. Compensation cost is recognized over the requisite service period and is not subsequently adjusted if the market condition is not met. For awards without a market-based triggering event, compensation cost is generally recognized on a straight-line basis over the requisite service period which is normally the vesting period.

The estimated fair value of options granted without a market-based triggering event is calculated using the Black-Scholes option pricing valuation model. This model takes into account several factors and assumptions. The risk-free interest rate is based on the yield on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumption at the time of grant. The expected life (estimated period of time outstanding) is estimated using the contractual term of the option and the effects of employees' expected exercise and post-vesting employment termination behavior. The Company uses a blended volatility rate based on the following: (i) volatility derived from daily closing price observations for the 10-year period ended on the valuation date, (ii) implied volatility derived from traded options for the period one week before the valuation date and (iii) average volatility for the 10-year periods ended on 15 anniversaries prior to the valuation date, using daily closing price observations. The expected dividend yield is based on expected dividends for the expected term of the stock options.

The assumptions used in the Black-Scholes option pricing valuation model for options granted by the Company in 2012, 2011 and 2010 are as follows:

	2012	2011	2010
Risk-free interest rate	1.26%-1.27%	2.28%-2.90%	3.15%-3.20%
Expected life (in years)	6.50	6.75	6.75
Expected volatility	26.2%-26.4%	25.4%-25.8%	26.3%-27.6%
Expected dividend yield	2.76%-2.80%	2.75%-2.86%	3.26%-3.52%

The estimated fair value of options granted with a market-based triggering event is calculated using a binomial valuation model. The factors and assumptions used in this model are similar to those utilized in the Black-Scholes option pricing valuation model except that the risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve over the contractual term of the option, and the expected life is calculated by the model. Since 2009, there have been no options granted with a market-based triggering event.

A summary of the status of the Company’s stock option awards as of December 31, 2012 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, 2012	38,895,109		$	29.21
Granted	3,547,733		$	31.88
Exercised	(6,892,731	)	$	26.01
Canceled or exchanged	—		—
Forfeited	(860,022	)	$	27.69
Expired	(2,644,296	)	$	42.85
Balance at December 31, 2012	32,045,793		$	29.10	4.5 years	186,467
Options vested or expected to vest at December 31, 2012	32,004,297		$	29.12	4.4 years	185,871
Options exercisable at December 31, 2012	16,115,605		$	28.85	3.8 years	106,606

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, 2012, 2011 and 2010 was $6.04, $6.67 and $4.85, respectively. The total intrinsic value of options exercised during the same periods was $57.7 million, $23.6 million and $0.5 million, respectively.

As of December 31, 2012, there was $18 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 1.3 years. Cash received from the exercise of stock options for the years ended December 31, 2012, 2011 and 2010 was $179.3 million, $111.7 million and $1.5 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 are available.

Restricted Stock Units and Performance Stock Units: Restricted stock units may be awarded under the Company's 2011 Incentive and Stock Award Plan. The Compensation Committee determines the restrictions on such units, when the restrictions lapse, when the units vest and are paid, and under what terms the units are forfeited. The cost of these awards is amortized over the vesting period, which is generally three years. Awards to senior executives and other employees may include three-year performance-based restricted stock units and three-year service-based restricted stock units. The payout of performance-based restricted stock units (payable in shares of the Company's common stock) may range, generally, from 0-200% of the number of units granted, based on the achievement of objective, pre-determined Company or operating company performance measures, generally, over a three-year performance period. The Company accounts for these awards as performance condition restricted stock units. The performance condition is not considered in the determination of grant date fair value of such awards. Compensation cost is recognized over the performance period based on management's estimate of the number of units expected to vest and is adjusted to reflect the actual number of shares paid out at the end of the three-year performance period. Beginning with awards granted on or after February 23, 2009, dividend equivalents are not paid out unless and until such time that the award vests.

A summary of the status of the Company's restricted stock units and performance stock units as of December 31, 2012 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, 2012	15,058,428		$	25.43	368,346		$	30.60
Granted	2,797,287		$	31.96	461,756		$	31.89
Vested	(8,209,388	)	$	23.97	(25,129	)	$	30.83
Forfeited	(682,089	)	$	28.49	(81,075	)	$	31.31
Adjustment due to performance	—		$	—	6,940		$	30.60
Non-vested balance at December 31, 2012	8,964,238		$	28.58	730,838		$	31.32

The weighted-average grant-date fair value of the Company's restricted stock units and performance stock units granted during the year ended December 31, 2011 was $30.46 and $30.60, respectively; the combined weighted-average grant-date fair value of the Company's restricted stock units and performance stock units granted during the year ended December 31, 2010 was $22.81. The total fair value of the shares distributed during the years ended December 31, 2012, 2011 and 2010 in connection with the Company's restricted stock units and performance stock units was $262.6 million, $249 million and $170.7 million, respectively.

The number of vested performance stock units includes any applicable performance adjustment shares. The adjustment due to performance reflects the incremental portion of the above-target payout (160%) of performance stock units awarded in February 2011 that vested during 2012 either in full or on a pro-rata basis due to certain types of termination of employment. There is no adjustment due to performance for performance stock units awarded in February 2012 that vested during 2012 due to certain types of termination of employment within the calendar year of grant since the payout of such awards is at 100% of target under the award's terms and conditions.

Restricted Stock: Restricted shares of the Company's common stock may be awarded under the 2011 Plan and are subject to restrictions on transferability and other restrictions, if any, as the Compensation Committee may impose. The Compensation Committee may also determine when and under what circumstances the restrictions may lapse and whether the participant receives the rights of a stockholder, including, without limitation, the right to vote and receive dividends. Unless the Compensation Committee determines otherwise, restricted stock that is still subject to restrictions is forfeited upon termination of employment. Shares granted, generally become unrestricted at the earlier of: (1) January 1 of the year following the vesting grant date anniversary or (2) the later of the recipient's normal or actual retirement date. For shares granted prior to 2004, the vesting grant date anniversary is ten years. For shares granted during 2004 and 2005, the vesting grant date anniversary is 7 years and 5 years, respectively. However, certain restricted shares granted in 2005 vested on the third anniversary of the grant date. There have been no restricted shares granted since 2005.

A summary of the status of the Company's restricted stock awards as of December 31, 2012 and changes during the period then ended is presented below:

	Shares		Weighted Average Grant Date Fair Value
Non-vested balance at January 1, 2012	51,700		$	46.86
Granted	—		$	—
Vested	(20,000	)	$	46.14
Forfeited	—		$	—
Non-vested balance at December 31, 2012	31,700		$	47.31

The total fair value of the Company's restricted stock distributed was $0.6 million for each of the years ended December 31, 2012 and December 31, 2011. There were no restricted stock distributions in 2010.

As of December 31, 2012, there was $135 million of unrecognized compensation cost related to the Company's restricted stock, restricted stock units and performance stock unit awards. The weighted-average period over which that cost is expected to be recognized is approximately 1 year.

Marsh & McLennan Companies Stock Purchase Plans

In May 1999, the Company's stockholders approved an employee stock purchase plan (the “1999 Plan”) to replace the 1994 Employee Stock Purchase Plan (the “1994 Plan”), which terminated on September 30, 1999 following its fifth annual offering. Under the current terms of the Plan, shares are purchased four times during the plan year at a price that is 95% of the average market price on each quarterly purchase date. Under the 1999 Plan, after including the available remaining unused shares in the 1994 Plan and reducing the shares available by 10,000,000 consistent with the Company's Board of Directors' action in March 2007, no more than 35,600,000 shares of the Company's common stock may be sold. Employees purchased 899,424 shares during the year ended December 31, 2012 and at December 31, 2012, 4,136,312 shares were available for issuance under the 1999 Plan. Under the 1995 Company Stock Purchase Plan for International Employees (the “International Plan”), after reflecting the additional 5,000,000 shares of common stock for issuance approved by the Company's Board of Directors in July 2002, and the addition of 4,000,000 shares due to a shareholder action in May 2007, no more than 12,000,000 shares of the Company's common stock may be sold. Employees purchased 111,073 shares during the year ended December 31, 2012 and there were 3,085,961 shares available for issuance at December 31, 2012 under the International Plan. The plans are considered non-compensatory.

Fair Value Disclosures [Abstract]

Fair Value Measurements

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 in ASC Topic No. 820 (“Fair Value Measurements and Disclosures”). 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, most U.S. Government and agency securities, money market mutual funds and certain other sovereign government obligations).

Assets and liabilities utilizing Level 1 inputs include exchange traded equity securities and mutual 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 utilizing Level 2 inputs include corporate and municipal bonds, senior notes and interest rate swaps.

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 (examples include private equity investments, certain commercial mortgage whole loans, and long-dated or complex derivatives including certain foreign exchange options and long-dated options on gas and power).

Liabilities utilizing Level 3 inputs include liabilities for contingent purchase consideration.

Valuation Techniques

Equity Securities & Mutual Funds - Level 1

Investments for which market quotations are readily available are valued at the sale price on their principal exchange, or official closing bid price for certain markets. If no sales are reported, the security is valued at its last reported bid price.

Other Sovereign Government Obligations, Municipal Bonds and Corporate Bonds - Level 2

The investments listed in the caption above are valued on the basis of valuations furnished by an independent pricing service approved by the trustees or dealers. Such services or dealers determine valuations for normal institutional-size trading units of such securities using methods based on market transactions for comparable securities and various relationships, generally recognized by institutional traders, between securities.

Interest Rate Swap Derivative - Level 2

The fair value of interest rate swap derivatives is based on the present value of future cash flows at each valuation date resulting from utilization of the swaps, using a constant discount rate of 1.6% compared to discount rates based on projected future yield curves. (See Note 12)

Senior Notes due 2014 - Level 2

The fair value of the first $250 million of Senior Notes maturing in 2014 is estimated to be the carrying value of those notes adjusted by the fair value of the interest rate swap derivative, discussed above. In the first quarter of 2011, the Company entered into two interest rate swaps to convert interest on a portion of its Senior Notes from a fixed rate to a floating rate. The swaps are designated as fair value hedging instruments. The change in the fair value of the swaps is recorded on the balance sheet. The carrying value of the debt related to these swaps is adjusted by an equal amount. (See Note 12).

Contingent Purchase Consideration Liability - Level 3

Purchase consideration for some acquisitions made by the Company includes contingent consideration arrangements. Contingent consideration arrangements are primarily based on meeting EBITDA and revenue targets over periods from two to four years. The fair value of contingent consideration is estimated as the present value of future cash flows that would result from the projected revenue and earnings of the acquired 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, 2012 and 2011.

(b) Included in cash and cash equivalents in the consolidated balance sheets.

(c) Included in other receivables in the consolidated balance sheets.

(d) Included in accounts payable and accrued liabilities and other liabilities in the consolidated balance sheets.

(e) Included in long term debt in the consolidated balance sheets.

During the year ended December 31, 2012, there were no assets or liabilities that transferred between Level 1 and Level 2 or between Level 2 and Level 3.

The table below sets forth a summary of the changes in fair value of the Company’s Level 3 liabilities for the years ended December 31, 2012 and December 31, 2011 that represent contingent purchase consideration related to acquisitions:

(In millions of dollars)	2012			2011
Balance at January 1,	$	110		$	106
Additions	27			14
Payments	(30		)	(13		)
Revaluation Impact	(44		)	3
Balance at December 31,	$	63		$	110

The fair value of the contingent purchase consideration liability is based on projections of revenue and earnings for the acquired entities that are reassessed on a quarterly basis. As set forth in the table above, based on the Company's ongoing assessment of the fair value of contingent purchase consideration liability, the Company recorded a net reduction in the estimated fair value of such liabilities for acquisitions made in prior periods of $44 million for the year ended December 31, 2012. A 5% increase in the above mentioned projections would increase the liability by approximately $30 million. A 5% decrease in the above mentioned projections would decrease the liability by approximately $20 million.

Fair Value of Long-term Investments

The Company has certain long-term investments, primarily related to investments in non-publicly traded private equity funds of $16 million and $38 million at December 31, 2012 and December 31, 2011, respectively, carried on the cost basis for which there are no readily available market prices. The carrying values of these investments approximates fair value. Management's estimate of the fair value of these non-publicly traded investments is based on valuation methodologies including estimates from private equity managers of the fair value of underlying investments in private equity funds. The ability to accurately predict future cash flows, revenue or earnings may impact the determination of fair value. The Company monitors these investments for impairment and makes appropriate reductions in carrying values when necessary. These investments would be classified as Level 3 in the fair value hierarchy and are included in Other assets in the consolidated balance sheets. The Company also has investments in publicly traded mutual funds of $19 million and $20 million at December 31, 2012 and December 31, 2011, related to voluntary deferred contribution plans. These investments are classified as Level 1 in the fair value hierarchy and are included in Other assets in the consolidated balance sheets.

Acquisitions [Abstract]

Acquisitions

Acquisitions

The Company’s acquisitions have been accounted for as purchases. Net assets and results of operations are included in the Company’s consolidated financial statements commencing at the respective effective purchase dates. In connection with acquisitions, the Company records the estimated value of the net tangible assets purchased and the value of the identifiable intangible assets purchased, which typically consist of purchased customer lists, trademarks and non-compete agreements. The valuation of purchased intangible assets involves significant estimates and assumptions. Any change in assumptions could affect the carrying value of such intangible assets.

During 2012, Marsh completed the following twelve acquisitions:

• January - Marsh acquired Alexander Forbes' South African brokerage operations, including Alexander Forbes Risk Services and related ancillary operations and insurance broking operations in Botswana and Namibia to expand Marsh's presence in Africa. Marsh subsequently closed the acquisitions of the Alexander Forbes operations in Uganda, Malawi and Zambia.

• March - Marsh & McLennan Agency business ("MMA") acquired KSPH, LLC, a middle-market employee benefits agency based in Virginia, and Marsh acquired Cosmos Services (America) Inc., the U.S. insurance brokerage subsidiary of ITOCHU Corp., which specializes in commercial property/casualty, personal lines, and employee benefits brokerage services to U.S. subsidiaries of Japanese companies.

• June - MMA acquired Progressive Benefits Solutions, an employee benefits agency based in North Carolina, and Security Insurance Services, Inc., a Wisconsin-based insurance agency which offers property/casualty and employee benefits products and services to individuals and businesses.

• August - MMA acquired Rosenfeld-Einstein, a South Carolina-based employee benefits service provider, and Eidson Insurance, a property/casualty and employee benefits services firm located in Florida.

• October - MMA acquired Howalt+McDowell, a South Dakota-based agency which offers property casualty, surety, personal protection and employee benefits insurance to individuals and businesses, and The Protector Group Insurance Agency, a Massachusetts-based agency which provides property casualty, employee benefits services, personal insurance and individual financial services.

• November - MMA acquired Brower Insurance, an Ohio-based company providing employee benefits, property/casualty and consulting services.

• December - MMA acquired McGraw Wentworth, a Michigan-based company providing consulting services to mid-sized organizations, and Liscomb Hood Mason, a Minnesota-based company providing property/casualty and employee benefits products and services.

The MMA acquisitions were made to expand Marsh's presence in the U.S. middle-market business.

During 2012, Mercer completed the following three acquisitions:

• February - Mercer acquired the remaining 49% of Yokogawa-ORC, a global mobility firm based in Japan, which was previously accounted for under the equity method, and Pensjon & Finans, a leading Norway-based financial investment and pension consulting firm.

• March - Mercer acquired REPCA, a France-based broking and advisory firm for employer health and benefits plans.

Total purchase consideration for acquisitions made during 2012 was $360 million, which consisted of cash paid of $252 million, deferred purchase and estimated contingent consideration of $46 million, and cash held in escrow of $62 million at December 31, 2011 that was released in the first quarter of 2012. Contingent consideration arrangements are primarily based on EBITDA and revenue targets over 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 2012, the Company also paid $59 million of deferred purchase consideration and $30 million of contingent consideration related to acquisitions made in prior years. In addition, the Company paid $3 million to purchase other intangible assets during 2012.

The following table presents the preliminary allocation of the acquisition cost to the assets acquired and liabilities assumed, based on their fair values:

(In millions)	2012

Prior Year Acquisitions

During 2011, the Company made seven acquisitions in its Risk and Insurance Services segment and five in its Consulting segment. In January 2011, Marsh acquired RJF Agencies, Inc., an independent insurance broking firm in the Midwest. In February 2011, Marsh acquired Hampton Roads Bonding, a surety bonding agency for commercial, road, utility, maritime and government contractors in the state of Virginia, and the Boston office of Kinloch Consulting Group, Inc. In July 2011, Marsh acquired Prescott Pailet Benefits, an employee benefits broker in the state of Texas. In October 2011, Marsh acquired the employee benefits division of Kaeding, Ernst & Co, a Massachusetts-based employee benefits, life insurance and financial planning consulting firm. In November 2011, Marsh acquired Gallagher & Associates, Inc., a property and casualty insurance agency based in Minnesota. In November 2011, Marsh acquired Seitlin Insurance, an insurance firm based in South Florida. These acquisitions were made to expand Marsh’s share in the middle-market through Marsh & McLennan Agency.

In January 2011, Mercer acquired Hammond Associates, an investment consulting company for endowments and foundations in the U.S. In June 2011, Mercer acquired Evaluation Associates LLC, an investment consulting firm. In July 2011, Mercer acquired Mahoney Associates, a health and benefits advisory firm based in South Florida. In August 2011, Mercer acquired Censeo Corporation, a human resource consulting firm based in Florida. In December 2011, Mercer acquired Alicia Smith & Associates, a Medicaid policy consulting firm based in Washington, D.C.

Total purchase consideration for the 2011 acquisitions was $197 million which consisted of cash paid of $164 million and deferred and estimated contingent consideration of $33 million. Contingent consideration arrangements are primarily based on EBITDA and revenue targets over 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. The Company also paid $27 million of deferred purchase and contingent consideration related to acquisitions made in prior years. In addition, the Company paid $4 million to purchase other intangible assets during 2011.

In the second quarter of 2011, Marsh acquired the remaining minority interest of a previously majority owned entity for total purchase consideration of $8 million and accounted for this acquisition under the accounting guidance for consolidations and non-controlling interests. This guidance requires that changes in a parent’s ownership interest while retaining financial controlling interest in a subsidiary be accounted for as an equity transaction. Stepping up the acquired assets to fair value or the recording of goodwill is not permitted. Therefore, the Company recorded a decrease to additional paid-in capital in 2011 of $2 million related to this transaction.

In the first quarter of 2011, the Company paid deferred purchase consideration of $13 million related to the purchase in 2009 of the minority interest of a previously controlled entity.

Pro-Forma Information

While the Company does not believe its acquisitions are material in the aggregate, the following unaudited pro-forma financial data gives effect to the acquisitions made by the Company during 2012 and 2011. In accordance with accounting guidance related to pro-forma disclosures, the information presented for current year acquisitions is as if they occurred on January 1, 2011 and reflects acquisitions made in 2011 as if they occured on January 1, 2010. The pro-forma information adjusts for the effects of amortization of acquired intangibles.

Claims, Lawsuits And Other Contingencies

Claims, Lawsuits And Other Contingencies

Claims, Lawsuits and Other Contingencies

Errors and Omissions Claims

The Company and its subsidiaries, particularly Marsh and Mercer, are subject to a significant number of claims, lawsuits and proceedings in the ordinary course of business. Such claims and lawsuits consist principally of alleged errors and omissions in connection with the performance of professional services, including the placement of insurance, the provision of actuarial services for corporate and public sector clients, and the provision of consulting services relating to the drafting and interpretation of trust deeds and other documentation governing pension plans. Certain of these claims, particularly in the U.S. and the U.K., seek damages, including punitive and treble damages, in amounts that could, if awarded, be significant. In establishing liabilities for errors and omissions claims in accordance with FASB ASC Subtopic No.450-20 (Contingencies-Loss Contingencies), the Company utilizes case level reviews by inside and outside counsel and an internal actuarial analysis to estimate potential losses. A liability is established when a loss is both probable and reasonably estimable. The liability is reviewed quarterly and adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, because we are unable, at the present time, to make a determination that a loss is both probable and reasonably estimable.

To the extent that expected losses exceed our deductible in any policy year, the Company also records an asset for the amount that we expect to recover under any available third-party insurance programs. The Company has varying levels of third-party insurance coverage, with policy limits and coverage terms varying significantly by policy year.

Governmental Inquiries and Related Claims

In January 2005, the Company and its subsidiary Marsh Inc. entered into a settlement agreement with the New York State Attorney General (“NYAG”) and the New York State Insurance Department to settle a civil complaint and related citation regarding Marsh's use of market service agreements with various insurance companies. The parties subsequently entered into an amended and restated settlement agreement in February 2010 that restored a level playing field for Marsh.

Numerous private party lawsuits based on similar allegations to those made in the NYAG complaint were commenced against the Company, one or more of its subsidiaries, and their current and former directors and officers. Most of these matters have been resolved. Four actions instituted by policyholders against the Company, Marsh and certain Marsh subsidiaries remain pending in federal court.

Our activities are regulated under the laws of the United States and its various states, the European Union and its member states, and the other jurisdictions in which we operate. In the ordinary course of business we are also subject to investigations, lawsuits and/or other regulatory actions undertaken by governmental authorities.

Other Contingencies-Guarantees

In connection with its acquisition of U.K.-based Sedgwick Group in 1998, the Company acquired several insurance underwriting businesses that were already in run-off, including River Thames Insurance Company Limited (“River Thames”), which we 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 reinsured up to £40 million by a related party of River Thames. Payment of claims under the reinsurance agreement is collateralized by segregated assets held in a trust. As of December 31, 2012, the reinsurance coverage exceeded the best estimate of the projected liability of the policies covered by the guarantee. To the extent River Thames or the reinsurer is unable to meet its obligations under those policies, a claimant may seek to recover from us 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 July3, 1980 and October6, 1983. Certain claims have been paid under the letter of credit and we anticipate that additional claimants may seek to recover against the letter of credit.

Kroll-related Matters

Under the terms of a stock purchase agreement with Altegrity, Inc. (“Altegrity”) related to Altegrity's purchase of Kroll from the Company in August 2010, a copy of which is attached as an exhibit to the Company's Quarterly Report on Form 10-Q for the period ended June30, 2010, we agreed to provide a limited indemnity to Altegrity with respect to certain Kroll-related litigation and regulatory matters.

**********

The pending proceedings and other matters described in this Note 15 on Claims, Lawsuits and Other Contingencies may expose the Company or its subsidiaries to liability for significant monetary damages and other forms of relief. Where a loss is both probable and reasonably estimable, we establish liabilities in accordance with FASB ASC Subtopic No.450-20 (Contingencies-Loss Contingencies). Except as described above, we are 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.

Long-Term Commitments [Abstract]

Long-Term Commitments

Long-term Commitments

The Company leases office facilities, equipment and automobiles under non-cancelable operating leases. These leases expire on varying dates; in some instances contain renewal and expansion options; do not restrict the payment of dividends or the incurrence of debt or additional lease obligations; and contain no significant purchase options. In addition to the base rental costs, occupancy lease agreements generally provide for rent escalations resulting from increased assessments for real estate taxes and other charges. Approximately 98% of the Company’s lease obligations are for the use of office space.

The consolidated statements of income include net rental costs of $416 million, $430 million and $421 million for 2012, 2011 and 2010, respectively, after deducting rentals from subleases ($10 million in 2012, $9 million in 2011 and $8 million in 2010). These net rental costs exclude rental costs and sublease income for previously accrued restructuring charges related to vacated space.

At December 31, 2012, the aggregate future minimum rental commitments under all non-cancelable operating lease agreements are as follows:

For the Years Ended December 31,	Gross Rental Commitments		Rentals from Subleases		Net Rental Commitments
(In millions of dollars)

The Company has entered into agreements, primarily with various service companies, to outsource certain information systems activities and responsibilities and processing activities. Under these agreements, the Company is required to pay minimum annual service charges. Additional fees may be payable depending upon the volume of transactions processed, with all future payments subject to increases for inflation. At December 31, 2012, the aggregate fixed future minimum commitments under these agreements are as follows:

U.S. Federal income taxes are not provided on temporary differences with respect to investments in foreign subsidiaries that are essentially permanent in duration, which at December 31, 2012 amounted to approximately $4.3 billion. The determination of the unrecognized deferred tax liability with respect to these investments is not practicable.

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,	2012		2011		2010
U.S. Federal statutory rate	35.0	%	35.0	%	35.0	%
U.S. state and local income taxes—net of U.S. Federal income tax benefit	1.9		1.6		1.9
Differences related to non-U.S. operations	(6.1	)	(6.5	)	(9.5	)
Other	(1.8	)	—		(0.9	)
Effective tax rate	29.0	%	30.1	%	26.5	%

The Company’s consolidated tax rate was 29.0%, 30.1% and 26.5% in 2012, 2011 and 2010, respectively. The tax rate in each year reflects foreign operations, which are taxed at rates lower than the U.S. statutory tax rate.

Valuation allowances had net increases of $23 million and decreases of $1 million in 2012 and 2011, respectively. During the respective years, adjustments of the beginning of the year balances of valuation allowances increased income tax expense by $16 million in 2012 and decreased income tax expense by $7 million in 2011. None of the cumulative valuation allowances relate to amounts which if realized would increase contributed capital in the future. Approximately 73% of the Company’s net operating loss carryforwards expire from 2013 through 2032, and others are unlimited. The potential tax benefit from net operating loss carryforwards at the end of 2012 comprised state and local, and non-U.S. tax benefits of $78 million and $90 million, respectively, before reduction for valuation allowances. Foreign tax credit carryforwards expire from 2018 through 2022.

The realization of deferred tax assets depends on generating future taxable income in the applicable jurisdiction during the periods in which the tax benefits are deductible or creditable. The Company, including Marsh have been profitable globally. However, tax liabilities are determined and assessed on a legal entity and jurisdictional basis. Certain taxing jurisdictions allow or require combined or consolidated tax filings.

In the United States, certain groups within the Company, which file on a combined basis, were profitable in 2011 and 2012, but incurred a loss in 2010 as a result of the cost resulting from the resolution of the ARMB matter. The Company assessed the realizability of its domestic deferred tax assets, particularly state deferred tax assets of Marsh relating to jurisdictions in which it files separate tax returns, state deferred tax assets of all of the Company's domestic operations related to jurisdictions in which the Company files a unitary or combined state tax return, and foreign tax credit carryforwards in the Company's consolidated U.S. federal tax return. When making its assessment about the realization of its domestic deferred tax assets at December 31, 2012, the Company considered all available evidence, placing particular weight on evidence that could be objectively verified. The evidence considered included (i) the profitability of the Company's U.S. operations in 2011 and 2012 and the cumulative period from 2010 through 2012, (ii) the nature, frequency, and severity of financial reporting losses incurred prior to 2011, (iii) profit trends evidenced by continued improvements in the Company's and Marsh's operating performance, (iv) the non-recurring nature of some of the items that contributed to the losses before 2011, (v) the carryforward periods for the net operating losses ("NOLs") and foreign tax credit carryforwards, (vi) the sources and timing of future taxable income, giving weight to sources according to the extent to which they can be objectively verified, and (vii) tax planning strategies that would be implemented, if necessary, to accelerate utilization of NOLs. Based on its assessment, the Company concluded that it is more likely than not that a substantial portion of these deferred tax assets are realizable and a valuation allowance was recorded to reduce the domestic tax assets to the amount that the Company believes is more likely than not to be realized. In the event sufficient taxable income is not generated in future periods, additional valuation allowances of up to approximately $270 million could be required relating to these domestic deferred tax assets. The realization of the remaining U.S. federal deferred tax assets is not as sensitive to U.S. profits because it is supported by anticipated repatriation of future annual earnings from the Company’s profitable global operations, consistent with the Company's historical practice. In addition, when making its assessment about the realization of its domestic deferred tax assets at December 31, 2012, the Company continued to assess the realizability of deferred tax assets of certain other entities with a history of recent losses, including other U.S. entities that file separate state tax returns and foreign subsidiaries, and recorded valuation allowances as appropriate.

Following is a reconciliation of the Company’s total gross unrecognized tax benefits for the years ended December 31, 2012, 2011 and 2010:

(In millions of dollars)	2012			2011			2010
Balance at January 1,	$	143		$	199		$	206
Additions, based on tax positions related to current year	26			7			7
Additions for tax positions of prior years	35			39			10
Reductions for tax positions of prior years	(41		)	(91		)	(6		)
Reductions due to reclassification of tax indemnifications on sale of Kroll	—			—			(3		)
Settlements	(6		)	(6		)	(4		)
Lapses in statutes of limitation	(40		)	(5		)	(11		)
Balance at December 31,	$	117		$	143		$	199

Of the total unrecognized tax benefits at December 31, 2012, 2011 and 2010, $96 million, $102 million and $123 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, 2012 , 2011 and 2010, before any applicable federal benefit, was $13 million, $17 million and $35 million, respectively.

As discussed in Note 5, the Company has provided certain indemnities related to contingent tax liabilities as part of the disposals of Putnam and Kroll. At December 31, 2012, 2011 and 2010, $6 million, $14 million and $75 million, respectively, included in the table above, relates to Putnam and Kroll positions included in consolidated Company tax returns. Since the Company remains primarily liable to the taxing authorities for resolution of uncertain tax positions related to consolidated returns, these balances will remain as part of the Company’s consolidated liability for uncertain tax positions. Any future charges or credits that are directly related to the disposal of Putnam and Kroll and the indemnified contingent tax issues, including interest accrued, will be recorded in discontinued operations as incurred. The balance of gross unrecognized tax benefits at January 1, 2010 in the chart above includes balances related to stand alone tax filings of Kroll that were reclassified and are included as part of the fair value liability for contingent tax indemnities following the sale transaction.

The Company is routinely examined by the jurisdictions in which it has significant operations. The Internal Revenue Service (IRS) is currently examining 2009 and 2010.   During 2011, the Company was accepted to participate in the IRS Compliance Assurance Process (CAP) which is structured to conduct real-time compliance reviews.  The IRS is currently examining 2011 and performing a pre-filing review of the Company's 2012 U.S. operations. New York State has examinations underway for various entities covering the years 2007 through 2010. At the end of 2012, Massachusetts issued Notices of Assessment for 2007 for various entities and the Company is currently appealing those assessments. During 2012, the United Kingdom completed its examination of tax year 2010 for various subsidiaries. There are no ongoing tax audits in the jurisdictions outside the U.S. in which the company has significant operations. The Company regularly considers the likelihood of assessments in each of the taxing jurisdictions resulting from examinations. The Company has established appropriate liabilities for uncertain tax positions in relation to the potential assessments. The Company believes the resolution of tax matters will not have a material effect on the consolidated financial position of the Company, although a resolution of tax matters could have a material impact on the Company's net income or cash flows and on its effective tax rate in a particular future period. It is reasonably possible that the total amount of unrecognized tax benefits will decrease between zero and approximately $25 million within the next twelve months due to settlement of audits and expiration of statutes of limitation.

Discontinued Operations

Discontinued Operations

As part of the disposal transactions for Putnam and Kroll, the Company provided certain indemnities, primarily related to pre-transaction tax uncertainties and legal contingencies. In accordance with applicable accounting guidance, liabilities were established related to these indemnities at the time of the sales and reflected as a reduction of the gain on disposal. Discontinued operations includes charges or credits resulting from the settlement or resolution of the indemnified matters, as well as adjustments to the liabilities related to such matters. Discontinued operations in 2011 includes credits of$50 millionfrom the resolution of certain legal matters and insurance recoveries, as well as the settlement of tax audits and the expiration of the statutes of limitations related to certain of the indemnified matters, primarily with respect to Putnam.

Marsh's BPO business, previously part of the Marsh U.S. Consumer business, provided policy, claims, call center and accounting operations on an outsourced basis to life insurance carriers. Marsh invested in a technology platform that was designed to make the Marsh BPO business scalable and more efficient. During 2011, Marsh decided that it would cease investing in the technology platform and instead exit the business via a sale. In the fourth quarter of 2011, management initiated a plan to sell the Marsh BPO business, which was completed in August 2012. The Company wrote off capitalized software of $17 million, net of tax, which is included in discontinued operations in 2011.

In the first quarter of 2010, Kroll completed the sale of KLS and on August 3, 2010, the Company completed the sale of Kroll to Altegrity.

Kroll’s results of operations are reported as discontinued operations in the Company’s consolidated statement of income for the portion of 2010 prior to Kroll's disposal. The year ended 2010 also includes the gain on the sale of Kroll and related tax benefits and the loss on the sale of KLS, which includes the tax provision of $36 million on the sale.

The Company’s tax basis in its investment in the stock of Kroll at the time of sale exceeded the recorded amount primarily as a result of prior impairments of goodwill recognized for financial reporting, but not tax. A $265 million deferred tax benefit was recorded in discontinued operations in 2010 as a result of the sale of Kroll.

Goodwill And Other Intangibles [Abstract]

Goodwill And Other Intangibles

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 test for each of its reporting units during the third quarter of each year. In accordance with applicable accounting guidance, the Company assesses qualitative factors to determine whether it is necessary to perform the two-step goodwill impairment test. The Company considered the numerous factors, which included that the fair value of each reporting unit exceeded its carrying value by a substantial margin in its most recent estimate of reporting unit fair values, whether significant acquisitions or dispositions occurred which might alter the fair values 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 evaluation in the third quarter of 2012 and concluded that a two-step goodwill impairment test was not required in 2012 and that goodwill was not impaired.

Other intangible assets that are not deemed to have an indefinite life are amortized over their estimated lives and reviewed for impairment upon the occurrence of certain triggering events in accordance with applicable accounting literature.

Changes in the carrying amount of goodwill are as follows:

(In millions of dollars)	2012		2011
Balance as of January 1, as reported	$	6,562	$	6,420
Goodwill acquired	226		124
Other adjustments(a)	4		18
Balance at December 31,	$	6,792	$	6,562

(a) Reflects increases due to the impact of foreign exchange in both years. 2012 also reflects a reduction due to purchase accounting adjustments.

The goodwill acquired of $226 million in 2012 (approximately $110 million of which is deductible for tax purposes) comprised of $196 million related to the Risk and Insurance Services segment and $30 million related to the Consulting segment.

Goodwill allocable to the Company’s reportable segments is as follows: Risk and Insurance Services, $4.7 billion and Consulting, $2.1 billion.

Amortized intangible assets consist primarily of the cost of client lists and trade names acquired. The gross cost and accumulated amortization at December 31, 2012 and 2011 is as follows:

(In millions of dollars)	2012						2011
	Gross Cost		Accumulated Amortization		Net Carrying Amount		Gross Cost		Accumulated Amortization		Net Carrying Amount
Amortized intangibles	$	814	$	345	$	469	$	666	$	265	$	401

The Company recorded an intangible asset impairment charge of $8 million in the third quarter of 2012 in the Risk & Insurance Services segment.

Aggregate amortization expense for the years ended December 31, 2012, 2011 and 2010 was $72 million, $65 million and $50 million, respectively, and the estimated future aggregate amortization expense is as follows:

Retirement Benefits [Abstract]

Retirement Benefits

Retirement Benefits

The Company maintains qualified and non-qualified defined benefit pension plans for its U.S. and non-U.S. eligible employees. The Company’s policy for funding its tax qualified defined benefit retirement plans is to contribute amounts at least sufficient to meet the funding requirements set forth by U.S. law and the laws of the non-U.S. jurisdictions in which the Company offers defined benefit plans.

Combined U.S. and non-U.S. Plans

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

	Pension  Benefits				Postretirement Benefits
	2012		2011		2012		2011
Weighted average assumptions:
Discount rate (for expense)	4.91	%	5.59	%	5.05	%	5.81	%
Expected return on plan assets	8.03	%	8.19	%	—		—
Rate of compensation increase (for expense)	3.09	%	4.08	%	—		—
Discount rate (for benefit obligation)	4.38	%	4.91	%	4.32	%	5.05	%
Rate of compensation increase (for benefit obligation)	2.43	%	3.09	%	—		—

The Company uses actuaries from Mercer, a subsidiary of the Company, to perform valuations of its pension plans. The long-term rate of return 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. The Company generally does not adjust the rate of return assumption from year to year if, at the measurement date, it is within the best estimate range, defined as between the 25^thand 75^thpercentile of the expected long-term annual returns in accordance with the “American Academy of Actuaries Pension Practice Council Note May 2001 Selecting and Documenting Investment Return Assumptions” and consistent with Actuarial Standards of Practice No. 27. Historical long-term average asset returns of each plan are also reviewed to determine whether they are consistent and reasonable compared with the best estimate range. 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 recorded.

The target asset allocation for the U.S. Plan is 58% equities and equity alternatives and 42% fixed income. At the end of 2012, the actual allocation for the U.S. Plan was 58% equities and equity alternatives and 42% fixed income. The target asset allocation for the U.K. Plan, which comprises approximately 82% of non-U.S. Plan assets, is 53% equities and equity alternatives and 47% fixed income. At the end of 2012, the actual allocation for the U.K. Plan was 52% equities and equity alternatives and 48% 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 rebalancing to ensure the actual portfolio remains consistent with target asset allocation ranges.

The discount rate selected for each U.S. plan is based on a model bond portfolio with coupons and redemptions that closely match the expected liability cash flows from the plan. Discount rates for non-U.S. plans are based on appropriate bond indices such as the Markit iBoxx £ Corporates AA 15+ index in the U.K. Projected compensation increases reflect current expectations as to future levels of inflation.

The components of the net periodic benefit cost for defined benefit and other postretirement plans are as follows:

Combined U.S. and significant non-U.S. Plans	Pension									Postretirement
For the Years Ended December 31,	Benefits									Benefits
(In millions of dollars)	2012			2011			2010			2012			2011			2010

Net periodic benefit cost	$	182		$	144		$	83		$	4		$	1		$	5

Plan Assets

For the U.S. plan, 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, 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. qualified plan, the category ranges are 53-63% for equities and equity alternatives, and 37-47% for fixed income. For the U.K. Plan, the category ranges are 50-56% for equities and equity alternatives, and 44-50% for fixed income. Asset allocation ranges are evaluated generally every three years. Asset allocation is monitored frequently and re-balancing actions are taken as appropriate.

Plan investments are exposed to stock market, interest rate, and credit risk. Concentrations of these risks are generally limited due to diversification by investment style within each asset class, diversification by investment manager, diversification by industry sectors and issuers, and the dispersion of investments across many geographic areas.

Unrecognized Actuarial Gains/Losses

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

The weighted average actuarial assumptions utilized in determining the above amounts for the U.S. defined benefit and other U.S. postretirement plans as of the end of the year are as follows:

	U.S. Pension Benefits				U.S. Postretirement Benefits
	2012		2011		2012		2011

Rate of compensation increase (for benefit obligation)	2.00	%	2.00	%	—		—

The projected benefit obligation, accumulated benefit obligation and aggregate fair value of plan assets for U.S. pension plans with accumulated benefit obligations in excess of plan assets were $5.2 billion, $5.1 billion and $3.9 billion, respectively, as of December 31, 2012 and $4.5 billion, $4.5 billion and $3.5 billion, respectively, as of December 31, 2011.

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 $5.2 billion and $3.9 billion, respectively, as of December 31, 2012 and $4.5 billion and $3.5 billion, respectively, as of December 31, 2011.

As of December 31, 2012, the U.S. qualified plan holds eight million shares of the Company’s common stock which were contributed to the Plan by the Company in 2005. This represents approximately 7% of that plan’s assets as of December 31, 2012. In addition, plan assets may be invested in funds managed by Mercer Investments.

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

U.S. Plans only	Pension Benefits									Postretirement Benefits

In December 2003, the Medicare Prescription Drug, Improvement and Modernization Act of 2003 became law. The net periodic benefit cost shown above for 2012, 2011 and 2010, respectively, includes the subsidy.

The assumed health care cost trend rate for Medicare eligibles is approximately 7.86% in 2012, gradually declining to 4.5% in 2028, and the rate for non-Medicare eligibles is 7.73% in 2012, gradually declining to 4.50% in 2028. Assumed health care cost trend rates have a small effect on the amounts reported for the U.S. health care plans because the Company caps its share of health care trend at 5%. A one percentage point change in assumed health care cost trend rates would have the following effects:

Effect on postretirement benefit obligation	$	1	$	(5	)

Estimated Future Contributions

The Company expects to fund approximately $25 million for its U.S. non-qualified plan in 2013. 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. There currently is no ERISA funding requirement for the U.S. qualified plan for 2013.

The non-U.S. defined benefit plans do not have any direct ownership of the Company’s common stock.

The pension plan in the United Kingdom holds a limited partnership interest in the Trident III private equity fund valued at approximately $200 million at December 31, 2012.

The projected benefit obligation, accumulated benefit obligation and fair value of plan assets for the non-U.S. pension plans with accumulated benefit obligations in excess of plan assets were $1.7 billion, $1.6 billion and $1.2 billion, respectively, as of December 31, 2012 and $1.4 billion, $1.3 billion and $1 billion, respectively, as of December 31, 2011.

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, 2012 and $7.6 billion and $7.0 billion, respectively, as of December 31, 2011.

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

The assumed health care cost trend rate was approximately 5.47% in 2012, gradually declining to 4.48% in 2031. Assumed health care cost trend rates can have a significant effect on the amounts reported for the non-U.S. health care plans. A one percentage point change in assumed health care cost trend rates would have the following effects:

Estimated Future Contributions

The Company expects to fund approximately $623 million to its non-U.S. pension plans in 2013. 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.

Estimated Future Benefit Payments

The Plan’s estimated future benefit payments for its pension and postretirement benefits (without reduction for Medicare subsidy receipts) at December 31, 2012 are as follows:

December 31,	Pension Benefits				Postretirement Benefits

Defined Benefit Plans Fair Value Disclosures

In December 2008 the FASB issued guidance for Employers’ Disclosures About Pension and Other Post Retirement Benefit Plan Assets. The guidance requires fair value plan asset disclosures for an employer’s defined benefit pension and postretirement plans similar to the guidance on Fair Value Measurements as well as (a) how investment allocation decisions are made, (b) the major categories of plan assets, and (c) significant concentrations of risk within plan assets.

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; and Level 3, which refers to investments valued based on significant unobservable inputs. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The following 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, 2012 and 2011.

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 and rights/warrants (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 paper (included in corporate obligations):  The fair value of commercial paper is estimated using observable market data such as maturity date, issue date, credit rating, current commercial paper rates and settlement date.

Commercial mortgage-backed and asset-backed securities (included in corporate obligations):  Fair value is determined using discounted cash flow models. Observable inputs are based on trade and quote activity of bonds with similar features including issuer vintage, purpose of underlying loan (first or second lien), prepayment speeds and credit ratings. The discount rate is the combination of the appropriate rate from the benchmark yield curve and the discount margin based on quoted prices.

Common/Collective trusts:  Valued at the quoted market prices of the underlying investments at year end.

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. The managers provide unaudited quarterly financial statements and audited annual financial statements which set forth the value of the fund. The valuations obtained from the managers are based on various analyses on the underlying holdings in each partnership, including financial valuation models and projections, comparable valuations from the public markets, and precedent private market transactions. Investments are valued in the accompanying financial statements based on the Plan’s beneficial interest in the underlying net assets of the partnership as determined by the partnership agreement.

Insurance group annuity contracts:  The fair values for these investments are based on the current market value of the aggregate accumulated contributions plus interest earned.

Swap assets and liabilities:  Fair values for interest rate swaps, equity index swaps and inflation swaps are estimated using a discounted cash flow pricing model. These models use observable market data such as contractual fixed rate, broker quotes, spot equity price or index value and dividend data. The fair values of credit default swaps are estimated using an income approach model which determines expected cash flows based on default probabilities from the issuer specific credit spread curve and credit loss recovery rates, both of which are dependent on market quotes.

Real estate investment trusts:  Valued at the closing price reported on an exchange.

Short-term investment funds:  Primarily high-grade money market instruments valued at net asset value at year-end.

Real estate: Valued by investment managers generally using proprietary pricing models.

Registered investment companies:  Valued at the closing price reported on the primary exchange.

Defined Contribution Plans

The Company maintains certain defined contribution plans for its employees, including the Marsh & McLennan Companies 401(k) Savings & Investment Plan (“401(k) Plan”), that are qualified under U.S. tax laws. Under these plans, eligible employees may contribute a percentage of their base salary, subject to certain limitations. For the 401(k) Plan, the Company matches a fixed portion of the employees’ contributions. The 401(k) Plan contains an Employee Stock Ownership Plan feature under U.S. tax law. Approximately $375 million of the 401(k) Plan’s assets at December 31, 2012 and $366 million at December 31, 2011 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 related to continuing operations was $50 million in 2012 and $48 million for 2011 and 2010.

Integration and Restructuring Costs

In 2012, the Company implemented restructuring actions which resulted in costs totaling $78 million million. Approximately $58 million of the restructuring charges are related to Mercer, approximately $51 million of which was incurred in the fourth quarter of 2012 related to senior management's recent operations review, including costs of approximately $16 million related to the disposal of Mercer's Canadian outsourcing business. The remaining restructuring costs consist primarily of severance and benefits, costs for future rent and other real estate costs. These costs were incurred as follows: Risk and Insurance Services—$8 million (all acquisition related); Consulting—$58 million (acquisition related—$1 million); and Corporate—$12 million.

Details of the restructuring liability activity from January 1, 2011 through December 31, 2012, including actions taken prior to 2012 are as follows:

(In millions of dollars)	Balance at 1/1/11		Expense Incurred		Cash Paid			Other			Balance at 12/31/11		Expense Incurred		Cash Paid			Other			Balance at 12/31/12

The Company had non-cash issuances of common stock under its share-based payment plan of $193 million, $197 million and $182 million for the years ended December 31, 2012, 2011 and 2010, respectively. The Company recorded stock-based compensation expense related to equity awards of $152 million, $165 million and $174 million for the years ended December 31, 2012, 2011 and 2010, respectively.

The consolidated statement of cash flows includes the cash flow impact of discontinued operations in each cash flow category. The cash flow impact of discontinued operations from the operating, financing and investing cash flow categories is as follows:

For the Year Ended December 31,
(In millions of dollars)	2012		2011		2010
Net cash provided by (used for) operations	$	—	$	11	$	(6	)
Net cash used for investing activities	$	—	$	—	$	(14	)
Effect of exchange rate changes on cash and cash equivalents	$	—	$	—	$	(2	)

The information above excludes the cash flow impacts of actual disposal transactions related to discontinued operations because the Company believes these transactions to be cash flows attributable to the parent company, arising from its decision to dispose of the discontinued operation. In 2010, the Company’s cash flow reflects cash provided by investing activities of $1.13 billion from the disposal of Kroll and $110 million related to the disposition of KLS.

Less current portion	260		260
	$	2,658	$	2,668

The senior notes in the table above are publically registered by the Company with no guarantees attached.

During the first quarter of 2012, the Company repaid its 6.25% fixed rate $250 million senior notes that matured. The Company used proceeds from the issuance of 2.3%five-year $250 million senior notes in the first quarter of 2012 to fund the maturing notes.

On July 15, 2011, the Company purchased a total of $600 million of outstanding notes comprised of $330 million of its 5.375% notes due in 2014 and $270 million of its 5.750% notes due in 2015. The Company acquired the notes at market value plus a tender premium, which exceeded the notes' carrying values.

The Company used proceeds from the issuance of 4.80%ten-year $500 million senior notes in the third quarter of 2011 and cash on hand to fund the amounts associated with the tendered bonds.

In February 2013, the Company repaid $250 million of maturing senior notes.

The Company and certain of its foreign subsidiaries maintain a $1.0 billion multi-currency five-year unsecured revolving credit facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. This facility requires the Company to maintain certain coverage and leverage ratios which are measured quarterly. There were no borrowings outstanding under this facility at December 31, 2012.

In December 2012, the Company closed on a $50 million, three-year delayed draw term loan facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. The Company has the ability to increase the loan amount by $100 million during the life of the loan. The facility requires the Company to maintain coverage ratios and leverage ratios consistent with the revolving credit facility discussed above. There were no borrowings under this facility at December 31, 2012.

Derivative Financial Instruments

In February 2011, the Company entered into two$125 million3.5-year interest rate swaps to hedge changes in the fair value of the first $250 million of the outstanding 5.375% senior notes due in 2014.

Under the terms of the swaps, the counter-parties will pay the Company a fixed rate of 5.375% and the Company will pay interest at a floating rate of three-month LIBOR plus a fixed spread of 3.726%. The maturity date of the senior notes and the swaps match exactly. The floating rate resets quarterly, with every second reset occurring on the interest payment date of the senior notes. The swaps net settle every six months on the senior note coupon payment dates. The swaps are designated as fair value hedging instruments and are deemed to be perfectly effective in accordance with applicable accounting guidance. The fair value of the swaps at inception was zero and subsequent changes in the fair value of the interest rate swaps are reflected in the carrying value of the interest rate swaps and in the consolidated balance sheet. The carrying value of the debt on the balance sheet was adjusted by an equal amount. The gain or loss on the hedged item (fixed rate debt) and the offsetting gain or (loss) on the interest rate swaps for the periods ended December 31, 2012 and December 31, 2011 is as follows:

	2012							2011
Income statement classification (In millions of dollars)	Loss on Swaps			Gain on Notes		Net Income Effect		Gain on Swaps		Loss on Notes			Net Income Effect
Other Operating Expenses	$	(1	)	$	1	$	—	$	7	$	(7	)	$	—

The amounts earned and owed under the swap agreements are accrued each period and are reported in interest expense. There was no ineffectiveness recognized in the periods presented. The portion of the debt acquired under the tender offer discussed above was not part of the first $250 million outstanding and therefore, did not impact the hedged portion of this debt.

Additional credit facilities, guarantees and letters of credit are maintained with various banks, primarily related to operations located outside the United States, aggregating $247 million at December 31, 2012 and $248 million at December 31, 2011. There were no outstanding borrowings under these facilities at December 31, 2012 or December 31, 2011.

Scheduled repayments of long-term debt in 2013 and in the four succeeding years are $260 million, $330 million, $491 million, $11 million and $262 million, respectively.

Fair value of Short-term and Long-term Debt

The estimated fair value of the Company’s short-term and long-term debt is provided below. Certain estimates and judgments were required to develop the fair value amounts. The fair value amounts shown below are not necessarily indicative of the amounts that the Company would realize upon disposition, nor do they indicate the Company’s intent or need to dispose of the financial instrument.

	December 31, 2012				December 31, 2011
(In millions of dollars)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Short-term debt	$	260	$	261	$	260	$	261
Long-term debt	$	2,658	$	2,986	$	2,668	$	2,958

The fair value of the Company’s short-term debt, which consists primarily of term debt maturing within the next year, 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.
