INFORMATION CONCERNING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains "forward-looking statements," as defined in the Private Securities Litigation Reform Act of 1995. These statements, which express management's current views concerning future events or results, use words like "anticipate," "assume," "believe," "continue," "estimate," "expect," "future," "intend," "plan," "project" and similar terms, and future or conditional tense verbs like "could," "may," "might," "should," "will" and "would." For example, we may use forward-looking statements when addressing topics such as: the outcome of contingencies; the expected impact of acquisitions and dispositions; the impact of competition; pension obligations; the impact of foreign currency exchange rates; our effective tax rates; changes in our business strategies and methods of generating revenue; the development and performance of our services and products; changes in the composition or level of our revenues; our cost structure, dividend policy, cash flow and liquidity; future actions by regulators; and the impact of changes in accounting rules.

Forward-looking statements are subject to inherent risks and uncertainties. Factors that could cause actual results to differ materially from those expressed or implied in our forward-looking statements include, among other things:

• our ability to maintain adequate safeguards to protect the security of confidential, personal or proprietary information, and the potential for the improper disclosure or use of such information, whether due to human error, improper action by employees, vendors or third parties, or as a result of a cyberattack;

• the impact of fluctuations in foreign currency exchange rates, particularly in light of the recent strengthening of the U.S. dollar against most other currencies worldwide;

• the impact of competition on our business, including the impact of our corporate tax rate, which is higher than the tax rate of some of our competitors;

• the impact on our global pension obligations of changes in discount rates and asset returns, as well as projected salary increases, mortality rates, demographics, and inflation, and the impact of cash contributions required to be made to our global defined benefit pension plans due to changes in the funded status of those plans;

• our exposure to potential liabilities arising from errors and omissions claims against us;

• our exposure to potential civil remedies or criminal penalties if we fail to comply with foreign and U.S. laws that are applicable in the domestic and international jurisdictions in which we operate, including trade sanctions laws relating to countries such as Cuba, Iran, Russia, Sudan and Syria, anti-corruption laws such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 2010 and local laws prohibiting corrupt payments to government officials;

• the extent to which we are able to retain existing clients and attract new business, and our ability to effectively incentivize and retain key employees;

• our ability to make acquisitions and dispositions and to integrate, and realize expected synergies, savings or benefits from, the businesses we acquire;

• our ability to successfully recover should we experience a disaster or other business continuity problem;

• the impact of changes in interest rates and deterioration of counterparty credit quality on our cash balances and the performance of our investment portfolios;

• the impact of potential rating agency actions on our cost of financing and ability to borrow, as well as on our operating costs and competitive position;

• changes in applicable tax or accounting requirements; and

• potential income statement effects from the application of FASB's ASC Topic No. 740 (“Income Taxes”) regarding accounting treatment of uncertain tax benefits and valuation allowances, including the effect of any subsequent adjustments to the estimates we use in applying this accounting standard.

The factors identified above are not exhaustive. Marsh & McLennan Companies and its subsidiaries operate in a dynamic business environment in which new risks may emerge frequently. Accordingly, we caution readers not to place undue reliance on any forward-looking statements, which are based only on information currently available to us and speak only as of the dates on which they are made. The Company undertakes no obligation to update or revise any forward-looking statement to reflect events or circumstances arising after the date on which it is made. Further information concerning Marsh & McLennan Companies and its businesses, including information about factors that could materially affect our results of operations and financial condition, is contained in the Company's filings with the Securities and Exchange Commission, including the "Risk Factors" section and the "Management’s Discussion and Analysis of Financial Condition and Results of Operations" section of our most recently filed Annual Report on Form 10-K.

MARSH & McLENNAN COMPANIES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.     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 activities 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 health, retirement, talent and investments. Within the investments business, Mercer provides delegated investment (fiduciary management) solutions to institutional investors (such as retirement plan sponsors and trustees) and to individual investors (primarily through the inclusion of funds managed by Mercer on defined contribution and wealth management platforms). As of March 31, 2015, Mercer had assets under management of $125 billion worldwide. 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 7 to the consolidated financial statements.

2.     Principles of Consolidation and Other Matters

The consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. While certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted pursuant to such rules and regulations for interim filings, the Company believes that the information and disclosures presented are adequate to make such information and disclosures not misleading. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 (the "2014 10-K").

The financial information contained herein reflects all adjustments consisting only of normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the Company’s consolidated financial statements as of and for the three-month periods ended March 31, 2015 and 2014.

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 $171 million related to regulatory requirements outside the U.S. or as collateral under captive insurance arrangements.

Investments

The Company holds investments in private companies and private equity funds. Investments in private equity funds are accounted for under the equity method of accounting using a consistently applied three-month lag period adjusted for any known significant changes from the lag period to the reporting date of the Company. The underlying private equity funds follow investment company accounting, where investments within the fund are carried at fair value. The Company records in earnings, investment gains/losses for its proportionate share of the change in fair value of the funds. Investments using the equity method of accounting are included in other assets in the consolidated balance sheets.

The caption “Investment income” in the consolidated statements of income comprises realized and unrealized gains and losses from investments recognized in current earnings. It includes, when applicable, other than temporary declines in the value of debt and available for sale securities and the change in value of the Company’s holdings in certain private equity funds, including equity method gains (losses) on its investment in the Trident funds. The Company’s investments may include direct investments in insurance or consulting companies and investments in

10

private equity funds. The Company recorded investment income of $2 million in the first quarter of 2015 compared to $13 million for the same period in 2014.

Income Taxes

The Company's effective tax rate in the first quarter of 2015 was 29.2% compared with 29.5% in the first quarter of 2014. These rates reflect non-U.S. income taxed at rates below the U.S. statutory rate, including the effect of repatriation, as well as the impact of discrete tax matters such as changes in circumstances that result in a change in judgment about the beginning balance in valuation allowances, the resolution of tax examinations and expirations of statutes of limitations.

The Company is routinely examined by tax authorities in the jurisdictions in which it has significant operations. The Company regularly considers the likelihood of assessments in each of the taxing jurisdictions resulting from examinations. When evaluating the potential imposition of penalties, the Company considers a number of relevant factors under penalty statutes, including appropriate disclosure of the tax return position, the existence of legal authority supporting the Company's position, and reliance on the opinion of professional tax advisors.

The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in tax returns. The Company's gross unrecognized tax benefits increased from

$97 million at December 31, 2014 to $100 million at March 31, 2015. It is reasonably possible that the total amount of unrecognized tax benefits will decrease between zero and approximately $22 million within the next twelve months due to settlements of audits and expirations of statutes of limitation.

3.     Fiduciary Assets and Liabilities

In its capacity as an insurance broker or agent, the Company collects premiums from insureds and, after deducting its commissions, remits the premiums to the respective insurance underwriters. The Company also collects claims or refunds from underwriters on behalf of insureds. Unremitted insurance premiums and claims proceeds are held by the Company in a fiduciary capacity. Risk and Insurance Services revenue includes interest on fiduciary funds of $5 million and $6 million for the three-month periods ended March 31, 2015 and 2014, respectively. The Consulting segment recorded fiduciary interest income of $1 million for each of the three-month periods ended March 31, 2015 and 2014. 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 $8.1 billion at March 31, 2015 and $7.3 billion atDecember 31, 2014. 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 $26 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.

4.    Per Share Data

Basic net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income 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 by the weighted average number of outstanding shares of the Company’s common stock, which have been adjusted for the dilutive effect of potentially issuable common shares. Reconciliations of the applicable income components used for diluted EPS - Continuing operations and basic weighted average common shares outstanding to diluted weighted average common shares outstanding are presented below. The reconciling items related to the calculation of diluted weighted average common shares outstanding are the same for net income attributable to the Company.

The Company had non-cash issuances of common stock of $64 million and $92 million for the three months ended March 31, 2015 and 2014, respectively, primarily related to its share-based payment plans. The Company recorded share-based compensation expense related to equity awards (excluding stock options) of $16 million and $26 million for the three-month periods ended March 31, 2015 and 2014, respectively.

9.    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 considers numerous factors, which include that the fair value of each reporting unit exceeds its fair value by a substantial margin in its most recent estimate of reporting unit fair values, whether significant acquisitions or dispositions occurred which might alter the fair value of its reporting units, macroeconomic conditions and their potential impact on reporting unit fair values, actual performance compared with budget and prior projections used in its estimation of reporting unit fair values, industry and market conditions, and the year-over-year change in the Company’s share price. The Company completed its qualitative assessment in the third quarter of 2014 and concluded that a two-step goodwill impairment test was not required in 2014, 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:

March 31,
(In millions of dollars)	2015			2014
Balance as of January 1, as reported	$	7,241		$	6,893
Goodwill acquired	12			267
Other adjustments(a)	(93		)	(1		)
Balance at March 31,	$	7,160		$	7,159

^(a)  Primarily reflects the impact of foreign exchange in each period.

Goodwill allocable to the Company’s reportable segments at March 31, 2015 is as follows: Risk & Insurance Services, $5 billion and Consulting, $2.2 billion.

16

Amortized intangible assets consist of the cost of client lists, client relationships and trade names acquired. The gross cost and accumulated amortization are as follows:

	March 31, 2015						December 31, 2014
(In millions of dollars)	Gross Cost		Accumulated Amortization		Net Carrying Amount		Gross Cost		Accumulated Amortization		Net Carrying Amount
Amortized intangibles	$	1,163	$	491	$	672	$	1,177	$	485	$	692

Aggregate amortization expense for the three months ended March 31, 2015 and2014 was $24 million and $22 million, respectively. The estimated future aggregate amortization expense is as follows:

For the Years Ending December 31,
(In millions of dollars)	Estimated Expense
2015 (excludes amortization through March 31, 2015)	$	66
2016	77
2017	74
2018	72
2019	73
Subsequent years	310

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 Financial Accounting Standards Board ("FASB"). The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy, for disclosure purposes, is determined based on the lowest level input that is significant to the fair value measurement. Assets and liabilities recorded in the consolidated balance sheets at fair value are categorized based on the inputs in the valuation techniques as follows:

Level 1. Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market (examples include active exchange-traded equity securities and money market mutual funds).

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.

17

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 and 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.

Contingent 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 resulting 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 March 31, 2015 and December 31, 2014.

	Identical Assets (Level 1)				Observable Inputs (Level 2)				Unobservable Inputs (Level 3)				Total
(In millions of dollars)	03/31/15		12/31/14		03/31/15		12/31/14		03/31/15		12/31/14		03/31/15		12/31/14

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

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

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

During the three-month period ended March 31, 2015, there were no assets or liabilities that were transferred between any of the levels.

The table below sets forth a summary of the changes in fair value of the Company’s Level 3 liabilities as of March 31, 2015 and 2014 that represent contingent consideration related to acquisitions:

(In millions of dollars)	2015			2014
Balance at January 1,	$	207		$	104
Additions	8			55
Payments	(19		)	(30		)
Revaluation Impact	10			4
Balance at March 31,	$	206		$	133

18

The fair value of the contingent liability is based on projections of revenue and earnings for the acquired entities that are reassessed on a quarterly basis. As set forth in the table above, based on the Company's ongoing assessment of the fair value of contingent consideration, the Company recorded a net increase in the estimated fair value of such liabilities for prior-period acquisitions of $10 million in the three-month period ended March 31, 2015. A 5% increase in the above mentioned projections would increase the liability by approximately $21 million. A 5% decrease in the above mentioned projections would decrease the liability by approximately $24 million.

Fair Value of Long-Term Investments

The Company holds investments in certain private companies, public companies and certain private equity investments that are accounted for using the equity method of accounting. The carrying value of these investments amounted to $399 million at March 31, 2015 and $388 million at December 31, 2014. The Company's investments in private equity funds were $74 million and $61 million at March 31, 2015 and December 31, 2014, respectively. The carrying values of these private equity investments approximates fair value. The underlying private equity funds follow investment company accounting, where investments within the fund are carried at fair value. The Company records in earnings, investment gains/losses for its proportionate share of the change in fair value of the funds. These investments would be classified as Level 3 in the fair value hierarchy and are included in other assets in the consolidated balance sheets.

During 2014, the Company purchased 34% of the common stock of Alexander Forbes. As of March 31, 2015, the carrying value of the Company’s investment in Alexander Forbes was approximately $278 million. As of March 31, 2015, the market value of the approximately 443 million shares of Alexander Forbes owned by the Company, based on the March 31, 2015 closing share price of 10.54 South African Rand per share, was approximately $386 million. The Company’s investment in Alexander Forbes and its other equity investments in private companies are accounted for using the equity method of accounting and included in revenue in the consolidated income statements and in other assets in the consolidated balance sheets. The Company records its share of income or loss on its equity method investments on a one quarter lag basis.

On February 24, 2015, Mercer purchased shares of common stock of Benefitfocus (NASDAQ:BNFT) constituting approximately 9.9% of BNFT's outstanding capital stock as of the acquisition date. The purchase price for the BNFT shares and certain other rights and other consideration was approximately $75 million. The Company has elected to account for this investment under the cost method of accounting as the shares purchased are categorized as restricted and cannot be sold for more than one year. When the restrictions on sale are less than one year in duration (January 1, 2017), the shares are expected to be classified as available for sale. This investment would then be classified as Level 2 in the fair value hierarchy and included in other assets in the consolidated balance sheets. The value of the BNFT shares based on the closing price on the NASDAQ at March 31, 2015 and without regard to the restrictions on sale was approximately $104 million.

11.    Retirement Benefits

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

The target asset allocation for the Company's U.S. Plan was 62% equities and equity alternatives and 38% fixed income and at March 31, 2015, the actual allocation for the Company's U.S. Plan was 61% equities and equity alternatives and 39% fixed income. The target asset allocation for the Company's U.K. Plans, which comprises approximately 83% of non-U.S. Plan assets, is 48% equities and equity alternatives and 52% fixed income. At March 31, 2015, the actual allocation for the U.K. Plans was 47% equities and equity alternatives and 53% 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 generally uses threshold-based portfolio re-balancing to ensure the actual portfolio remains consistent with target asset allocation ranges.

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

Combined U.S. and significant non-U.S. Plans	Pension						Post-retirement
For the Three Months Ended March 31,	Benefits						Benefits
(In millions of dollars)	2015			2014			2015			2014

In March 2015, the Company amended its U.S. Post-65 retiree medical reimbursement plan (the "RRA plan"), resulting in its termination, with benefits to certain participants paid through December 31, 2016. As a result of the termination of the RRA plan, the Company recognized a net credit of approximately $125 million in the first quarter of 2015.

After completion of a consultation period with affected colleagues, in January 2014, the Company amended its U.K. defined benefit pension plans to close those plans to future benefit accruals effective August 1, 2014 and replaced those plans, along with its existing U.K. defined contribution plans, with a new, comprehensive defined contribution arrangement. This change resulted in a curtailment of the U.K. defined benefit plans, and as required under GAAP, the Company re-measured the defined benefit plans’ assets and liabilities at the amendment date, based on assumptions and market conditions at that date. As a result of the re-measurement, the projected benefit obligation ("PBO") increased by approximately $147 million and the funded status decreased by approximately $137 million. The change in the PBO and in the funded status relates primarily to a decrease in the discount rate at the re-measurement date. The net periodic benefit costs recognized in 2014 were the weighted average resulting from the December 31, 2013 measurement and the January 2014 re-measurement. The Company recognized a curtailment gain of $65 million in the first quarter of 2014, primarily resulting from the recognition of the remaining unamortized prior service credit related to a plan amendment made in December 2012. This gain was mostly offset by the cost of a transition benefit for certain employees most impacted by the amendment, which is not part of net periodic pension cost.

The weighted average actuarial assumptions utilized to calculate the net periodic benefit costs for the U.S. and significant non-U.S. defined benefit plans are as follows:

Combined U.S. and significant non-U.S. Plans	Pension Benefits				Post-retirement Benefits
March 31,	2015		2014		2015		2014
Weighted average assumptions:
Expected return on plan assets	7.25	%	7.53	%	—	%	—	%
Discount rate	3.79	%	4.74	%	4.08	%	5.03	%
Rate of compensation increase	2.42	%	2.64	%	—	%	—	%

The Company made approximately $42 million of contributions to its U.S. and non-U.S. defined benefit plans in the first three months of 2015. The Company expects to contribute approximately $152 million to its non-qualified U.S. pension and non-U.S. pension plans during the remainder of 2015.

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

In March 2015, the Company issued $500 million of 2.35%five-year senior notes. The Company intends to use the net proceeds for general corporate purposes.

In September 2014, the Company issued $300 million of 2.35%five-year senior notes and $500 million of 3.50%10.5 year senior notes. In October 2014, a significant portion of the net proceeds of this offering were used to redeem $630 million of debt, including $230 million of 5.75% senior notes due in September 2015 and $400 million of 9.25% senior notes due in 2019. Total cash outflow related to this transaction was approximately $765 million, including a $137 million cost for early redemption, which was reflected as a charge in the consolidated statements of income in the fourth quarter of 2014.

In May 2014, the Company issued $600 million of 3.50%ten-year senior notes. The net proceeds of this offering were used for general corporate purposes, which included the repayment of $320 million of the existing 5.375% senior notes, which matured on July 15, 2014.

On March 27, 2014, the Company and certain of its foreign subsidiaries amended and restated its $1.0 billion facility into a $1.2 billion multi-currency five-year unsecured revolving credit facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. This facility expires in March 2019 and requires the Company to maintain certain coverage and leverage ratios which are tested quarterly. There were no borrowings outstanding under this facility at March 31, 2015.

In December 2012, the Company closed on a $50 million, three-year term loan facility. The interest rate on this facility at March 31, 2015 was 1.17%, which 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. The Company had $50 million of borrowings outstanding under this facility at March 31, 2015.

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.

	March 31, 2015				December 31, 2014
(In millions of dollars)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Short-term debt	$	61	$	61	$	11	$	11
Long-term debt	$	3,828	$	4,009	$	3,376	$	3,493

The fair value of the Company’s short-term debt, which consists primarily of term debt maturing in 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.    Restructuring Costs

The Company recorded total restructuring costs of $2 million in the first three months of 2015 primarily for future rent under non-cancelable leases. These costs were incurred in Corporate.

Details of the restructuring activity from January 1, 2014 through March 31, 2015, which includes liabilities from actions prior to 2015, are as follows:

(In millions of dollars)	Liability at 1/1/14		Amounts Accrued		Cash Paid			Other			Liability at 12/31/14		Amounts Accrued		Cash Paid			Other			Liability at 3/31/15
Severance	$	11	$	4	$	(8	)	$	—		$	7	$	—	$	(2	)	$	—		$	5
Future rent under non-cancelable leases and other costs	113		8		(35		)	(1		)	85		2		(5		)	(1		)	81
Total	$	124	$	12	$	(43	)	$	(1	)	$	92	$	2	$	(7	)	$	(1	)	$	86

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, depending on the nature of the items.

14.    Common Stock

During the first three months of 2015, the Company repurchased approximately 5.3 million shares of its common stock for consideration of $300 million. In May 2014, the Board of Directors of the Company authorized share repurchases of up to $2 billion of the Company's common stock. At March 31, 2015, the Company remains authorized to purchase additional shares of its common stock up to a value of approximately $1 billion. There is no time limit on the authorization. During the first three months of 2014, the Company repurchased 2 million shares of its common stock for consideration of $100 million.

15.    Claims, Lawsuits and Other Contingencies

Litigation Matters

The Company and its subsidiaries are subject to a significant number of claims, lawsuits and proceedings in the ordinary course of business. Such claims and lawsuits consist principally of alleged errors and omissions in connection with the performance of professional services, including the placement of insurance, the provision of actuarial services for corporate and public sector clients, the provision of investment advice and investment management services to pension plans, the provision of advice relating to pension buy-out transactions and the

23

provision of consulting services relating to the drafting and interpretation of trust deeds and other documentation governing pension plans. These claims may seek damages, including punitive and treble damages, in amounts that could, 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 uses 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.

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

Governmental Inquiries and Enforcement Matters

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

Other Contingencies-Guarantees

In connection with its acquisition of U.K.-based Sedgwick Group in 1998, the Company acquired several insurance underwriting businesses that were already in run-off, including River Thames Insurance Company Limited (“River Thames”), which the Company sold in 2001. Sedgwick guaranteed payment of claims on certain policies underwritten through the Institute of London Underwriters (the “ILU”) by River Thames. The policies covered by this guarantee 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 March 31, 2015, 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 July 3, 1980 and October 6, 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 June 30, 2010, the Company 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, the Company establishes liabilities in accordance with FASB ASC Subtopic No. 450-20 (Contingencies - Loss Contingencies). Except as described above, the Company is not able at this time to provide a reasonable estimate of the range of possible loss attributable to these matters or the impact they may have on the Company's consolidated results of operations, financial position or cash flows. This is primarily because these matters are still developing and involve complex issues subject to inherent uncertainty. Adverse determinations in one or more of these matters could have a material impact on the Company's consolidated results of operations, financial condition or cash flows in a future period.

16.    Segment Information

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

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

▪ Consulting, comprising Mercer and Oliver Wyman Group

The accounting policies of the segments are the same as those used for the consolidated financial statements described in Note 1 to the Company’s 2014 Form 10-K. Segment performance is evaluated based on segment operating income, which includes directly related expenses, and charges or credits related to integration and restructuring but not the Company’s corporate-level expenses. Revenues are attributed to geographic areas on the basis of where the services are performed.

17.    New Accounting Guidance

In February 2015, the FASB issued new accounting guidance intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations and securitization structures. The guidance focuses on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. The guidance is effective for periods beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact of the adoption of the guidance on its financial condition and results of operations.

In January 2015, the FASB issued new accounting guidance that eliminated the concept of extraordinary items. The guidance is effective for annual periods beginning after December 15, 2015. The guidance may be adopted prospectively, or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided the guidance is applied from the beginning of the fiscal year of adoption. Adoption of the guidance is not expected to materially affect the Company's financial condition, results of operations or cash flows.

In June 2014, the FASB issued new accounting guidance to clarify the treatment of share-based payment awards that require a specific performance target to be achieved in order for employees to be eligible to vest in the awards which include terms that may provide that the performance conditions could be achieved after an employee completes the requisite service period. The guidance requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, a reporting entity should apply the existing guidance as it relates to awards with performance conditions that affect vesting. The guidance is effective for annual periods beginning after December 15, 2015. Early adoption is permitted. Adoption of the guidance is not expected to materially affect the Company's financial condition, results of operations or cash flows.

In May 2014, the FASB issued new accounting guidance to clarify the principles for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that principle, the entity should apply the following steps: identify the contract(s) with the customer, identify the performance obligations in the contract(s), determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when (or as) the entity satisfies a performance obligation. The guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. Entities are permitted to adopt the guidance under one of the following methods: retrospectively to each prior reporting period presented (with certain practical expedients allowed) or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application. If an entity elects this transition method, it must provide disclosures in reporting periods that include the date of initial application of the amount by which each financial statement line item is affected in the current reporting period by application of the guidance as compared to guidance that was in effect before the change, and an explanation for the reasons for significant changes. The Company is currently evaluating the impact of the adoption of the guidance on its financial condition and results of operations.

In April 2014, the FASB issued new accounting guidance which changes the criteria for reporting discontinued operations and enhances disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations, such as disposal of a major geographic area or a major line of business, should be presented as discontinued operations. Those strategic shifts should have a major impact on the organization's operations and financial results. In addition, the new guidance requires expanded disclosures about discontinued operations. The guidance is effective for fiscal years beginning on or after December 15, 2014. Adoption of the guidance did not affect the Company's financial condition, results of operations or cash flows.

The Company's consolidated operating income increased 9% to $735 million in the first quarter of 2015 compared with $673 million in the prior year. This reflects the combined impact of a 1% decrease in revenue and a 4% decrease in expense. In the first quarter of 2015, the Company was adversely impacted by the strengthening of the U.S. dollar, which had the effect of reducing the translated value of the Company’s foreign earnings while pension expense worldwide increased due to lower interest rates. The impact of these headwinds was more than offset in the quarter by the impact of a net credit from the termination of the Company's post-65 retiree medical reimbursement plan in the U.S. (the "RRA plan") of approximately $125 million. Risk and Insurance Services operating income increased $40 million or 8% while Consulting operating income increased $23 million or 10% compared with the same period last year.

Income from continuing operations increased $41 million, or 9%, primarily reflecting the increase in operating income discussed above and a decrease in interest expense, partly offset by a decrease in investment income. Diluted net income per share from continuing operations increased 11% to $0.89, reflecting the increase in income from continuing operations and a 2% decrease in the average number of diluted shares outstanding as compared to the same period last year. Shares issued related to the vesting of share awards and exercise of employee stock options were more than offset by share repurchases over the past four quarters.

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, certain items that affect comparability, such as the revenue impact of acquisitions and dispositions, including transfers among businesses, may impact period-to-period comparisons of revenue. Underlying revenue measures the change in revenue from one period to another by isolating these impacts. The impact of foreign currency exchange fluctuations, acquisitions and dispositions, including transfers among businesses, on the Company’s operating revenues by segment was as follows:

29

Revenue

Consolidated revenue for the first quarter of 2015 was $3.2 billion, a decrease of 1% on a reported basis, reflecting a 4% increase on an underlying basis and a 1% increase from the impact of acquisitions, which were more than offset by a decrease of 6% from the impact of foreign currency translation.

Revenue in the Risk and Insurance Services segment for the first quarter of 2015 was $1.8 billion, a decrease of 2% from the same period last year. Revenue increased 3% on an underlying basis and 2% from the impact of acquisitions, offset by a 6% decrease from the impact of foreign currency translation. Consulting revenue of $1.4 billion in the first quarter of 2015 decreased 1% from the same period in 2014. Revenue increased 5% on an underlying basis as compared to the same period last year, offset by the impact of foreign currency translation.

Operating Expense

Consolidated operating expense in the first quarter decreased 4% compared to the same period last year and was flat on an underlying basis. First quarter results reflect a net benefit from actions relating to the RRA plan that more than offset higher expenses related to pension plans.

Risk and Insurance Services

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

For the Three Months Ended March 31,
(In millions of dollars)	2015			2014
Revenue	$	1,803		$	1,839
Compensation and Benefits	862			941
Other Expenses	408			405
Expense	1,270			1,346
Operating Income	$	533		$	493
Operating Income Margin	29.6		%	26.8		%

Revenue

Revenue in the Risk and Insurance Services segment in the first quarter of 2015 was $1.8 billion, a decrease of 2% as compared to the same period last year, reflecting the impact of a 6% decrease from foreign currency translation, partly offset by a 3% increase in underlying revenue and a 2% increase from acquisitions.

In Marsh, revenue in the first quarter of 2015 was $1.4 billion, a decrease of 2% compared with the same quarter of the prior year, reflecting a 7% decrease from foreign currency translation, partly offset by a 3% increase in acquisitions and an increase of 3% on an underlying basis. The increase in underlying revenue was driven primarily by new business. The international division grew 3% on an underlying basis, with growth of 2% in EMEA, 5% in Asia Pacific and 6% in Latin America. Underlying revenue increased 3% in U.S./Canada.Guy Carpenter's first quarter revenue decreased 4% compared to the same period in the prior year, reflecting a 4% decrease from the impact of foreign exchange translation. Underlying revenue increased 2% as compared to the same period last year due to growth in Global Specialties, primarily Marine and Lloyd's Property. International operations showed strong results and expansion in U.S. Treaty drove the U.S. Operations.

Expense

Expenses in the Risk and Insurance Services segment decreased 6% in the first quarter of 2015 compared with the same period last year, or 2% on an underlying basis. Foreign currency translation reduced expense by 6%, offset by a 2% increase related to acquisitions. The decrease in underlying expenses reflects the impact of the net benefit from the termination of the RRA plan, partly offset by higher base salaries and pension costs.

30

Consulting

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

For the Three Months Ended March 31,
(In millions of dollars)	2015			2014
Revenue	$	1,421		$	1,432
Compensation and Benefits	783			813
Other Expenses	390			394
Expense	1,173			1,207
Operating Income	$	248		$	225
Operating Income Margin	17.4		%	15.8		%

Revenue

Consulting revenue in the first quarter of 2015 decreased 1% reflecting a 5% increase on an underlying basis and a 1% increase related to acquisitions, which were more than offset by a 6% decrease from the impact of foreign currency translation. Mercer's revenue decreased 2% to $1.0 billion. On an underlying basis, Mercer's revenue increased 4% compared to the same period last year. The increase in underlying revenue was driven bygrowth in Health,Talent and Investments, which increased 3%, 4% and 13%, respectively. Oliver Wyman's revenue increased 4% to $384 million in the first quarter of 2015 as compared to the same period last year, reflecting an 8% increase on an underlying basis, a 2% increase from acquisitions, partly offset by a decrease of 6% from the impact of foreign currency translation.

In February 2015, Mercer made a $75 million strategic investment in Benefitfocus (NASDAQ:BNFT), a benefits technology provider. The investment expands the relationship between Mercer Marketplace, MMC's private healthcare exchange, and Benefitfocus.

Expense

Consulting expenses in the first quarter of 2015 decreased 3% from the first quarter of 2014 as a 6% decrease from the impact of foreign currency translation was partly offset by a 3% increase in underlying expenses. The underlying expense increase in the first quarter of 2015 was primarily due to higher base salaries, partly offset by the impact of the net benefit from the termination of the RRA plan.

Corporate and Other

Corporate expenses in the first quarter of 2015 were $46 million compared with $45 million in the prior year.

Interest

Interest income earned on corporate funds was $3 million in the first quarter of 2015, compared with $5 million in the first quarter of 2014, reflecting alower level of invested funds and lower effective interest rates. Interest expense decreased $6 million in 2015 compared with the first quarter of 2014. The decrease was due to lower average interest rates compared with the prior year.

Investment Income

The caption "Investment income" in the consolidated statements of income comprises realized and unrealized gains and losses from investments recognized in current earnings. It includes, when applicable, other than temporary declines in the value of debt and available-for-sale securities and equity method gains or losses on its investment in private equity. The Company's investments may include direct investments in insurance or consulting companies and investments in private equity funds. The Company recorded investment income of $2 million in the first quarter of 2015 compared to $13 million for the same period in 2014. The gains recorded in 2015 primarily relate to our investments in private equity funds. Investment income in 2014 included $7 million related to our general partner carried interest in Trident III that was no longer subject to claw-back, and gains of $6 million primarily related to our investments in private equity funds. At March 31, 2015, the Company had deferred performance fees of approximately $20 million related to Trident III. The timing of recognition of the remaining deferred performance fees from Trident III is unknown and is not controlled by the Company.

31

Income Taxes

The Company's effective tax rate in the first quarter of 2015 was 29.2% compared with 29.5% in the first quarter of 2014. The rates reflect non-U.S. income taxed at rates below the U.S. statutory rate, including the effect of repatriation.

The effective tax rate is sensitive to the geographic mix and repatriation of the Company's earnings, which may result in higher or lower tax rates. U.S. federal and state corporate tax rates substantially exceed tax rates applicable in most jurisdictions outside the U.S. A significant portion of the Company's profits are earned outside the U.S. In 2015, the forecasted pre-tax income in the U.K., Canada, Australia, Germany, and Bermuda is expected to account for approximately 60% of the Company's total non-U.S. pre-tax income, with estimated effective rates in those countries of 21%, 27%, 30%, 33% and 0%, respectively. Consequently, continued improvement in the profitability of the Company's U.S.-based operations would tend to result in higher effective tax rates. A loss in one jurisdiction generally cannot offset earnings in another, and within certain jurisdictions profits and losses may not offset between entities. Consequently, losses in certain operations may require valuation allowances affecting the effective tax rate, depending on estimates of the realizability of associated deferred tax assets. The tax rate is also sensitive to changes in unrecognized tax benefits, including the impact of settled tax audits and expired statutes of limitation.

Changes in tax laws or tax rulings may have a significant impact on our effective tax rate. Discussions continue within Congress and the Administration about broad reform of the corporate tax system in the U.S. It is not possible to predict the ultimate outcome of these discussions. Future legislation could have a material impact on our effective tax rate and consolidated financial statements due to reforms that could include changes in the corporate tax rate and in the way U.S. corporations are taxed on foreign earnings.

The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in the tax return. The Company's gross unrecognized tax benefits increased from $97 million at December 31, 2014 to $100 million at March 31, 2015. It is reasonably possible that the total amount of unrecognized tax benefits will decrease by an amount between zero and approximately $22 million within the next twelve months due to settlements of audits and expirations of statutes of limitation.

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, for share repurchases 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, 2014, the Company had approximately $1.3 billion of cash and cash equivalents in its foreign operations, substantially all of which is considered to be permanently invested in those operations to fund foreign investments and working capital needs. At the current time, the Company does not intend to repatriate any of this cash. The non-U.S. cash and cash equivalents considered permanently reinvested includes approximately $171 million of operating funds required to be maintained for regulatory requirements or as collateral under certain captive insurance arrangements. The Company expects to continue its practice of repatriating foreign funds out of current annual earnings. The analysis of the portion of 2015 earnings that the Company expects to repatriate and the portion that will be permanently reinvested will be finalized later in the year as the amount of non-U.S. earnings and the Company's cash requirements become more certain. 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, which could result in higher effective tax rates in the future.

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

Operating Cash Flows

The Company used $530 million of cash from operations for the three months ended March 31, 2015, compared with $380 million used by operations for the same period in 2014. These amounts reflect the net income of the Company during those periods, excluding gains or losses from investments and from the disposition of businesses, adjusted for non-cash charges, and changes in working capital which relate primarily to the timing of payments of accrued liabilities or receipts of assets and pension contributions. The use of cash is driven primarily by cash award payments, which are generally paid in the first quarter of each each year.

Pension Related Items

The Company's policy for funding its tax-qualified defined benefit plans is to contribute amounts at least sufficient to meet the funding requirements set forth in the applicable laws or regulations of the U.S. and other jurisdictions. During the first three months of 2015, the Company contributed $36 million to its non-U.S. pension plans and $6 million to its U.S. pension plans. In the first quarter of 2014, the Company contributed $47 million to its non-U.S. pension plans and $7 million to its U.S. pension plans.

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.

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 83% of non-U.S. plan assets. 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. In March 2014, the Company and the Trustee of the U.K. Defined Benefits Plans agreed to a funding deficit recovery plan for the U.K. defined benefit pension plans. The current agreement with the Trustee sets out the annual deficit contributions which would be due based on the deficit at December 31, 2012. The funding level is subject to re-assessment, in most cases on November 1^st of each year. If the funding level on November 1^st has sufficiently improved, no deficit funding contributions will be required in the following year, and the contribution amount will be deferred. As part of a long-term strategy, which depends on having greater influence over asset allocation and overall investment decisions,

33

the Company has agreed to support annual deficit contributions by the U.K. operating companies under certain circumstances, up to GBP 450 million over a seven-year period.

As a result of the significant improvement in funded status during 2013, which included the $250 million deficit pre-funding contribution discussed above, no additional deficit recovery contributions were required in 2014. Based on the funding test carried out at November 1, 2014, Company contributions to the U.K. plans in 2015 are expected to be $54 million. The U.K. employers also contribute an expense allowance each year of approximately $9 million.

The Company expects to fund an additional $133 million to its non-U.S. defined benefit plans over the remainder of 2015, comprising approximately $84 million to plans outside of the U.K. and $49 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 funded status of the plan.

After completion of a consultation period with affected colleagues, in January 2014, the Company amended its U.K. defined benefit pension plans to close those plans to future benefit accruals effective August 1, 2014 and replaced those plans, along with its existing defined contribution plans, with a new, comprehensive defined contribution arrangement. This change resulted in a curtailment of the U.K. defined benefit plans, and as required under GAAP, the Company re-measured the defined benefit plans’ assets and liabilities at the amendment date, based on assumptions and market conditions at that date. As a result of the re-measurement, the Projected Benefit Obligation ("PBO") increased by approximately $147 million and the funded status decreased by approximately $137 million. The change in the PBO and in the funded status relates primarily to a decrease in the discount rate at the re-measurement date. The Company recognized a curtailment gain of $65 million in the first quarter of 2014, primarily resulting from the recognition of the remaining unamortized prior service credit related to a plan amendment made in December 2012. This gain was largely offset by the cost of a transition benefit to certain employees most impacted by the amendment.

Financing Cash Flows

Net cash provided by financing activities was $71 million for the period ended March 31, 2015, compared with $118 million net cash used for the same period in 2014.

In March 2015, the Company issued $500 million of 2.35% five-year senior notes. The Company intends to use the net proceeds for general corporate purposes.

In September 2014, the Company issued $300 million of 2.35% five-year senior notes and $500 million of 3.50% 10.5 year senior notes. In October 2014, a significant portion of the net proceeds of this offering was used to redeem $630 million of debt, including $230 million of 5.75% senior notes due in September 2015 and $400 million of 9.25% senior notes due in 2019. Total cash outflow related to this transaction was approximately $765 million, including a $137 million cost for early redemption, which is reflected as a charge in the consolidated statements of income in the fourth quarter of 2014.

During the second quarter of 2014, the Company issued $600 million of 3.5% ten-year senior notes. A portion of the net proceeds of this offering was used for general corporate purposes, including the repayment of $320 million of 5.375% senior notes that matured in July 2014.

The Company and certain of its foreign subsidiaries maintain a $1.2 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, which are set forth below. This facility expires in March 2019 and requires the Company to maintain certain coverage and leverage ratios which are tested quarterly. There were no borrowings outstanding under this facility at March 31, 2015.

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 an agreed 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 current revolving credit facility discussed above. The Company had $50 million of borrowings under this facility at March 31, 2015.

The Company's senior debt is currently rated Baa1 by Moody's and A- 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.

During the first three months of 2015, the Company paid $19 million of contingent payments related to acquisitions made in prior periods. These payments are split between financing and operating cash flows in the consolidated statements of cash flows. The portion of these payments reflected as a financing activity is $6 million, which

34

represents payments related to the contingent consideration liability that was recorded on the date of acquisition. Payments related to increases in the contingent consideration liability subsequent to the date of acquisition, which were $13 million for the first quarter of 2015, are reflected as operating cash flows. In the first three months of 2015, the Company paid $26 million of deferred purchase consideration related to acquisitions made in prior years. Remaining deferred cash payments of approximately $72 million and estimated future contingent consideration payments of $206 million for acquisitions completed in the first three months of 2015 and in prior years are recorded in accounts payable and accrued liabilities or other liabilities in the consolidated balance sheet at March 31, 2015.

In the first three months of 2014, the Company paid $30 million of contingent payments related to acquisitions made in prior periods. Of this amount, $20 million was reported as financing cash flows and $10 million as operating cash flows. In addition, in the first three months of 2014, the Company paid $6 million of deferred purchase consideration related to acquisitions made in prior years.

In May 2014, the Board of Directors increased the Company's share repurchase program to $2 billion. At March 31, 2015, the Company remains authorized to purchase additional shares of its common stock up to a value of approximately $1 billion. There is no time limit on this authorization.

During the first three months of 2015, the Company repurchased approximately 5.3 million shares of its common stock for consideration of $300 million. During the first three months of 2014, the Company repurchased approximately 2 million shares of its common stock for consideration of $100 million.

The Company paid dividends on its common shares of $151 million ($0.28 per share) during the first three months of 2015, as compared with $137 million ($0.25 per share) during the first three months of 2014.

Investing Cash Flows

Net cash used for investing activities amounted to $194 million in the first three months of 2015, compared with $416million used during the same period in 2014.

The Company made 3 acquisitions during the first three months of 2015. Cash used for these acquisitions, net of cash acquired, was $16 million.

During 2014, Mercer acquired 34% of the common shares of South Africa-based Alexander Forbes Group Holdings Limited ("Alexander Forbes"). Mercer purchased its stake in Alexander Forbes in two tranches at 7.50 South African Rand per share. On July 24, 2014, the Company purchased 14.9% of Alexander Forbes common shares for approximately $137 million, and on October 2014, the Company paid approximately $166 million for the remaining 19.1% of Alexander Forbes common shares. The investment in Alexander Forbes is accounted for using the equity method and included in other assets in the consolidated balance sheet.

The Company madesix acquisitions during the first three months of 2014. Cash used for these acquisitions, net of cash acquired was $313 million.

The Company used cash of $91 million to purchase fixed assets and capitalized software in the first three months of 2015, compared with $99 million in the first three months of 2014, primarily related to computer equipment and software purchases, software development costs and the refurbishing and modernizing of office facilities.

On February 24, 2015, Mercer purchased shares of common stock of Benefitfocus (NASDAQ:BNFT) constituting approximately 9.9% of BNFT's outstanding capital stock as of the acquisition date. The purchase price for the BNFT shares and certain other rights and other consideration was approximately $75 million.

The Company has commitments for potential future investments of approximately $75 million in three private equity funds that invest primarily in financial services companies.

Commitments and Obligations

The Company’s contractual obligations of the types identified in the table below were of the following amounts as of March 31, 2015 (In millions of dollars):

	Payment due by Period
Contractual Obligations	Total		Within 1 Year		1-3 Years		4-5 Years		After 5 Years
Current portion of long-term debt	$	61	$	61	$	—	$	—	$	—
Long-term debt	3,841		—		274		1,076		2,491
Interest on long-term debt	1,359		144		283		261		671
Net operating leases	2,138		309		516		383		930
Service agreements	393		175		159		54		5
Other long-term obligations	307		67		202		36		2
Total	$	8,099	$	756	$	1,434	$	1,810	$	4,099

The above does not include unrecognized tax benefits of $100 million, accounted for under ASC Topic No. 740, as the Company is unable to reasonably predict the timing of settlement of these liabilities, other than approximately $4 million that may become payable within one year. 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 for underfunded plans of approximately $1.9 billion because the timing and amount of ultimate payment of such liability is dependent upon future events, including, but not limited to, future returns on plan assets and changes in the discount rate used to measure the liabilities. The Company expects to contribute approximately $19 million and $133 million to its U.S. and non-U.S. pension plans, respectively, in the remainder of 2015.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Market Risk and Credit Risk

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

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

(In millions of dollars)	March 31, 2015
Cash and cash equivalents invested in money market funds, certificates of deposit and time deposits	$	1,104
Fiduciary cash and investments	$	4,585

Based on the above balances, if short-term interest rates increased or decreased by 10%, or 8 basis points, over the course of the remainder of the year, annual interest income, including interest earned on fiduciary funds, would increase or decrease by approximately $2 million.

In addition to interest rate risk, our cash and cash equivalents 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 in response to market conditions. The majority of cash and fiduciary fund investments are invested in short-term bank deposits.

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 55% of total revenue. We periodically use forward contracts 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 tend 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 net operating income by approximately $54 million. In the fourth quarter of 2014 and the first quarter of 2015, the U.S. dollar strengthened significantly against most currencies. If exchange rates at March 31, 2015 hold constant throughout 2015, the Company estimates the year-over-year impact from conversion of foreign currency earnings would reduce full year net operating income by approximately $120 million. In Continental Europe, the largest amount of revenue from renewals for the Risk & Insurance segment occurs in the first quarter. Consequently, a significant portion of the year-over-year foreign exchange impact occurs in the first quarter.

Equity Price Risk

The Company holds investments in both public and private companies as well as private equity funds that invest primarily in financial services companies. The Company holds publicly traded investments of $92 million of which $17 million are classified as available for sale and $75 million are accounted for using the cost method, as the shares are categorized as restricted and cannot be sold for more than one year. Non-publicly traded investments of $13 million are accounted for using the cost method and an additional $399 million of investments are accounted for using the equity method. These investments are subject to risk of changes in market value, which if determined to be other than temporary, could result in realized impairment losses. The Company periodically reviews the carrying value of such investments to determine if any valuation adjustments are appropriate under the applicable accounting pronouncements.

SIXTH SUPPLEMENTAL INDENTURE, dated as of March 6, 2015 between MARSH & McLENNAN COMPANIES, INC., a Delaware corporation (the “Issuer”), and THE BANK OF NEW YORK MELLON, a New York banking corporation, as Trustee (the “Trustee”)

W I T N E S S E T H:

WHEREAS, the Issuer and the Trustee executed and delivered an Indenture, dated as of July 15, 2011 (the “Base Indenture” and, as supplemented hereby, the “Indenture”), to provide for the issuance by the Issuer from time to time of senior debt securities evidencing its unsecured indebtedness, to be issued in one or more series as provided in the Indenture;

WHEREAS, pursuant to a Board Resolution, the Issuer has authorized the issuance of a series of securities evidencing its senior indebtedness, consisting initially of $500,000,000 aggregate principal amount of 2.350% Senior Notes due 2020 (the “Original Notes” and, together with all the Additional Notes (as defined herein), if any, hereinafter referred to, the “Notes”);

WHEREAS, the entry into this Sixth Supplemental Indenture by the parties hereto is in all respects authorized by the provisions of the Indenture;

WHEREAS, the Issuer desires to establish the terms of the Notes in accordance with Section 2.01 of the Indenture and to establish the form of the Notes in accordance with Section 2.02 of the Indenture; and

WHEREAS, all acts and requirements necessary to make this Sixth Supplemental Indenture a valid and legally binding indenture and agreement according to its terms have been done.

NOW, THEREFORE, for and in consideration of the premises, the Issuer and the Trustee mutually covenant and agree for the equal and proportionate benefit of the respective holders from time to time of the Notes as follows:

ARTICLE 1

Section 1.01. Terms of Notes. The following terms relating to the Notes are hereby established:

(a)The Notes shall constitute a series of securities having the title “2.350% Senior Notes due 2020.”

(b)The aggregate principal amount of the Original Notes that may be authenticated and delivered under the Indenture (except Notes authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 2.05, 2.06, 2.07 or 9.04 of the Base Indenture) shall be up to $500,000,000.

(c)The entire outstanding principal of the Notes shall be payable on March 6, 2020 plus any unpaid interest accrued to such date.

(d)The rate at which the Notes shall bear interest shall be 2.350% per annum; the date from which interest shall accrue on the Notes shall be March 6,

2015 or from the most recent Interest Payment Date to which interest has been paid; the Interest Payment Dates for the Notes on which interest will be payable shall be March 6 and September 6 in each year, beginning September 6, 2015; the regular record dates for the interest payable on the Notes on any Interest Payment Date shall be the February 21 or August 21 immediately preceding the applicable Interest Payment Date; and the basis upon which interest on the Notes shall be calculated shall be that of a 360‑day year consisting of twelve 30‑day months.

(e)(i) The Notes may be redeemed in whole at any time or in part from time to time, at the option of the Issuer.

(ii) The redemption price (the “Redemption Price”) of the Notes to be redeemed shall be calculated as follows, plus, in each case, accrued and unpaid interest on the principal amount being redeemed to but excluding the redemption date:

(A) If the redemption date is prior to February 6, 2020, the Notes to be redeemed may be redeemed by the Issuer at a Redemption Price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal of and interest on the Notes to be redeemed (exclusive of interest accrued to the date of redemption) discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the then current Treasury Rate plus 15 basis points.

(B) If the redemption date is on or after February 6, 2020, the Notes to be redeemed may be redeemed by the Issuer at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed.

(iii) (A) In case the Issuer shall desire to exercise such right to redeem all or, as the case may be, a portion of the Notes in accordance with Section 1.01(e)(i) above, the Issuer shall, or shall cause the Trustee to, give notice of such redemption to holders of the Notes to be redeemed by transmitting a notice of such redemption not less than 30 days and not more than 60 days before the date fixed for redemption to such holders. Any notice that is delivered in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the registered holder received the notice. In any case, failure duly to give such notice to the holder of any Note designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of the proceedings for the redemption of any other Note.

Each such notice of redemption shall specify the amount of Notes to be redeemed, the date fixed for redemption and the applicable Redemption Price at which the Notes to be redeemed are to be redeemed, and shall state that payment of the Redemption Price of such Notes to be redeemed will be made at the office or agency of the Issuer in the Borough of Manhattan, the City and State of New York, upon presentation and surrender of such Notes, that interest accrued to the date fixed for redemption will be paid as specified in said notice and, that from and after said date interest will cease to accrue; except that interest shall continue to

2

accrue on any Note or portion thereof with respect to which the Issuer defaults in the payment of such Redemption Price and accrued interest. If less than all the Notes are to be redeemed, the notice to the holders of the Notes to be redeemed in whole or in part shall specify the particular Notes to be redeemed. In case the Notes are to be redeemed in part only, the notice shall state the portion of the principal amount thereof to be redeemed, and shall state that on and after the redemption date, upon surrender of such security, a new Note in principal amount equal to the unredeemed portion thereof will be issued.

(B) If the Trustee is to provide notice to the holders of the Notes in accordance with this Section 1.01(e)(iv), for a partial or full redemption, the Issuer shall give the Trustee at least 45 days’ notice in advance of the date fixed for redemption as to the aggregate principal amount of Notes to be redeemed, and thereupon, in the case of a partial redemption, the Trustee shall select, in accordance with the procedures of the Depository or as the Trustee shall deem appropriate and fair in its discretion and that may provide for the selection of a portion or portions (equal to two thousand U.S. dollars ($2,000) or integral multiples of $1,000 in excess thereof) of the principal amount of Notes of a denomination larger than $2,000, the Notes to be redeemed and shall thereafter promptly notify the Issuer in writing of the numbers of the Notes to be redeemed, in whole or in part.

The Issuer may, if and whenever it shall so elect, by delivery of instructions signed on its behalf by its President or any Vice President, instruct the Trustee or any paying agent to call all or any part of the Notes for redemption and to give notice of redemption in the manner set forth in this Section, such notice to be in the name of the Issuer or its own name as the Trustee or such paying agent may deem advisable. In any case in which notice of redemption is to be given by the Trustee or any such paying agent, the Issuer shall deliver or cause to be delivered to, or permit to remain with, the Trustee or such paying agent, as the case may be, such Security Register, transfer books or other records, or suitable copies or extracts therefrom, sufficient to enable the Trustee or such paying agent to give any notice that may be required under the provisions of this Section.

Subject to Section 2.11 of the Base Indenture, the Issuer shall not be required (i) to issue, register the transfer of or exchange any Notes during a period beginning at the opening of business 15 days before the day of the delivery of a notice of redemption of the Notes selected for redemption and ending at the close of business on the day of such delivery, or (ii) to register the transfer of or exchange any Notes so selected for redemption in whole or in part, except the unredeemed portion of any such Notes being redeemed in part.

If the giving of notice of redemption shall have been completed as above provided, the Notes or portions of the Notes to be redeemed specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable Redemption Price, and interest on such Notes shall cease to accrue on and after the date fixed for redemption, unless the Issuer shall default in the payment of such Redemption Price and accrued interest.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker is provided with fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per year equal to the semiannual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

With respect to Section 1.01(e)(ii)(A) above, the Trustee shall be entitled to conclusively rely upon the calculations of the Independent Investment Banker.

Any such Additional Notes will be a part of the series having the same terms as the Original Notes, provided that, if any additional notes subsequently issued are not fungible for U.S. federal income tax purposes with any notes previously issued, such additional notes shall trade under a separate CUSIP. The aggregate principal amount of the Additional Notes, if any, shall be unlimited. The Original Notes and the Additional Notes, if any, of such series shall constitute one series for all purposes under this Sixth Supplemental Indenture, including, without limitation, amendments, waivers and redemptions.

Section 1.04. Amendment of Section 6.01(a)(i) of the Base Indenture. Solely for the purposes of the Notes, Section 6.01(a)(i) of the Base Indenture is hereby amended by replacing that section in its entirety with the following:

“the Company defaults in the payment of any installment of interest on the Notes (as defined in this Supplemental Indenture), as and when the same shall become due and payable, and continuance of such default for a period of 30 days; provided, however, that a valid extension of an interest payment period by the Company in accordance with the terms of any indenture supplemental hereto, shall not constitute a default in the payment of interest for this purpose.”

2.350% Senior Notes due 2020

MARSH & McLENNAN COMPANIES, INC., a Delaware corporation (the “Issuer”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or its registered assigns, the principal sum of FIVE HUNDRED MILLION DOLLARS ($500,000,000) (which aggregate principal amount may from time to time be increased or decreased to such other aggregate principal amounts by adjustments made on the Schedule of Increases or Decreases in Global Security attached hereto) on March 6, 2020 and to pay interest on said principal sum from March 6, 2015 or from the most recent interest payment date (each such date, an “Interest Payment Date”) to which interest has been paid or duly provided for semiannually on March 6 and September 6 of each year commencing September 6, 2015 at the rate of 2.350% per annum until the principal hereof shall have become due and payable, and on any overdue principal and premium, if any, and (without duplication and to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum. The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360‑day year of twelve 30‑day months. In the event that any date on which interest is payable on this Note is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay). The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture (hereafter defined), be paid to the person in whose name this Note (or one or more Predecessor Securities, as defined in said Indenture) is registered at the close of business on the regular record date for such interest installment which shall be the February 21 or August 21 preceding such Interest Payment Date. Any such interest installment not punctually paid or duly provided for (as defined in the Indenture, the “Defaulted Interest”) shall forthwith cease to be payable to the registered holders on such regular record date, and may be paid to the person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a special record date to be fixed by the Trustee for the payment of such Defaulted Interest, which shall not be more than 15 nor less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment or at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. The principal of (and premium, if any) and the interest on this Note shall be payable at the office or agency of the Trustee maintained for that purpose in any coin or currency of the United States of America which at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Issuer by check mailed to the registered holder at such address as shall appear in the Security Register. Notwithstanding the foregoing, so long as the registered holder of this Note is

A-2

Cede & Co., the payment of the principal of (and premium, if any) and interest on this Note will be made at such place and to such account as may be designated by DTC.

The indebtedness evidenced by this Note is, to the extent provided in the Indenture, senior and unsecured and will rank in right of payment on parity with all other senior unsecured obligations of the Issuer.

This Note shall not be entitled to any benefit under the Indenture hereinafter referred to or be valid until the Certificate of Authentication hereon shall have been signed manually by or on behalf of the Trustee.

The provisions of this Note are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place.

2.350% Senior Notes due 2020

This Note is one of a duly authorized series of Securities (referred to in the Base Indenture (hereafter defined)), of the Issuer (herein sometimes referred to as the “Notes”), all such Securities issued or to be issued in one or more series under and pursuant to an indenture (the “Base Indenture”), dated as of July 15, 2011 between the Issuer and The Bank of New York Mellon, as Trustee (the “Trustee”), as supplemented in the case of the Notes by the Sixth Supplemental Indenture, dated as of March 6, 2015, between the Issuer and the Trustee (the Base Indenture, as so supplemented, the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer and the holders of the Notes. This series of Notes is initially limited in aggregate principal amount as specified in said Sixth Supplemental Indenture. This series of Notes and any Additional Notes of this series shall constitute one series for all purposes under the Indenture, including without limitation, amendments, waivers and redemptions. The terms and conditions of this series of Notes and any Additional Notes of this series (other than the issue price, the date of issuance, the payment of interest accruing prior to the issue date of the Additional Notes and the first payment of interest following such issue date) shall be the same and shall bear the same CUSIP number.

The Notes may be redeemed in whole at any time or in part from time to time, at the option of the Issuer. The redemption price (the “Redemption Price”) of the Notes to be redeemed shall be calculated as follows, plus, in each case, accrued and unpaid interest on the principal amount being redeemed to but excluding the redemption date:

(a)If the redemption date is prior to February 6, 2020, the Notes to be redeemed may be redeemed by the Issuer at a Redemption Price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal of and interest on the Notes to be redeemed (exclusive of interest accrued to the date of redemption) discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the then current Treasury Rate plus 15 basis points.

(b)If the redemption date is on or after February 6, 2020, the Notes to be redeemed may be redeemed by the Issuer at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed.

In case the Issuer shall desire to exercise such right to redeem all or, as the case may be, a portion of the Notes, the Issuer shall, or shall cause the Trustee to, give notice of such redemption to holders of the Notes to be redeemed by transmitting a notice of such redemption not less than 30 days and not more than 60 days before the date fixed for redemption to such holders. Any notice that is delivered in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the registered holder received the notice. In any case, failure duly to give such notice to the holder of any Note designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of the proceedings for the redemption of any other Note.

A-8

Each such notice of redemption shall specify the amount of Notes to be redeemed, the date fixed for redemption and the applicable Redemption Price at which the Notes are to be redeemed, and shall state that payment of the Redemption Price of such Notes to be redeemed will be made at the office or agency of the Issuer in the Borough of Manhattan, the City and State of New York, upon presentation and surrender of such Notes, that interest accrued to the date fixed for redemption will be paid as specified in said notice and, that from and after said date interest will cease to accrue; except that interest shall continue to accrue on any such Note or portion thereof with respect to which the Issuer defaults in the payment of such Redemption Price and accrued interest. If less than all the Notes are to be redeemed, the notice to the holders of the Notes to be redeemed in whole or in part shall specify the particular Notes to be redeemed. In case any Note is to be redeemed in part only, the notice that relates to such Note shall state the portion of the principal amount thereof to be redeemed, and shall state that on and after the redemption date, upon surrender of such security, a new Note in principal amount equal to the unredeemed portion thereof will be issued.

If the Trustee is to provide notice to the holders of the Notes as described herein, for a partial or full redemption, the Issuer shall give the Trustee at least 45 days’ notice in advance of the date fixed for redemption as to the aggregate principal amount of Notes to be redeemed, and thereupon, in the case of a partial redemption, the Trustee shall select, in accordance with the procedures of the Depository or as the Trustee shall deem appropriate and fair in its discretion and that may provide for the selection of a portion or portions (equal to two thousand U.S. dollars ($2,000) or integral multiples of $1,000 in excess thereof) of the principal amount of such Notes of a denomination larger than $2,000, the Notes to be redeemed and shall thereafter promptly notify the Issuer in writing of the numbers of the Notes to be redeemed, in whole or in part.

The Issuer may, if and whenever it shall so elect, by delivery of instructions signed on its behalf by its President or any Vice President, instruct the Trustee or any paying agent to call all or any part of the Notes for redemption and to give notice of redemption in the manner set forth in this Note, such notice to be in the name of the Issuer or its own name as the Trustee or such paying agent may deem advisable. In any case in which notice of redemption is to be given by the Trustee or any such paying agent, the Issuer shall deliver or cause to be delivered to, or permit to remain with, the Trustee or such paying agent, as the case may be, such Security Register, transfer books or other records, or suitable copies or extracts therefrom, sufficient to enable the Trustee or such paying agent to give any notice by mail that may be required under the provisions stated herein.

Subject to Section 2.11 of the Base Indenture, the Issuer shall not be required (i) to issue, register the transfer of or exchange any Notes during a period beginning at the opening of business 15 days before the day of the delivery of a notice of redemption of the Notes selected for redemption and ending at the close of business on the day of such delivery, or (ii) to register the transfer of or exchange any Notes so selected for redemption in whole or in part, except the unredeemed portion of any such Notes being redeemed in part.

If the giving of notice of redemption shall have been completed as above provided, the Notes or portions of the Notes to be redeemed specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable Redemption Price, and interest on such Notes shall cease to accrue on and

A-9

after the date fixed for redemption, unless the Issuer shall default in the payment of such Redemption Price and accrued interest.

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Securities of all of the series at the time Outstanding affected thereby (all such series voting together as a single class), as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Base Indenture or of any supplemental indenture or of modifying in any manner the rights of the holders of the Notes; provided, however, that no such supplemental indenture shall, without the consent of the holders of each Security then Outstanding and affected thereby (i) extend the fixed maturity of any Securities, including the Notes, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, or (ii) reduce the aforesaid percentage of Securities, the holders of which are required to consent to any such supplemental indenture. The Indenture also contains provisions permitting the holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding affected thereby (all such series voting together as a single class), to waive any past default in the performance of any of the covenants contained in the Base Indenture, or established pursuant to the Base Indenture with respect to such series, and its consequences, except a default in the payment of the principal of or premium, if any, or interest on any Securities, including the Notes, in which case, each such affected series voting as a separate class. Any such consent or waiver by the registered holder of this Note (unless revoked as provided in the Base Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and of any Note issued in exchange herefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the time and place and at the rate and in the money herein prescribed.

The Issuer is subject to certain covenants contained in the Indenture with respect to, and for the benefit of the holders of, the Notes. The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Issuer’s compliance with the covenants contained in the Indenture or with respect to reports or other certificates filed under the Indenture; provided, however, that nothing herein shall relieve the Trustee of any obligations to monitor the Issuer’s timely delivery of all reports and certificates required under Section 5.03 of the Base Indenture and to fulfill its obligations under Article VII of the Indenture. If an Event of Default as defined in the Indenture with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

As provided in and subject to the provisions of the Indenture, the holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or Trustee or for any other remedy thereunder, unless such holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the holders of not less than 25% in principal amount

A-10

of the Outstanding Notes (in the case of an Event of Default described in clauses (a)(i) or (a)(ii) of Section 6.01 of the Base Indenture, each such series voting as a separate class, and in the case of an Event of Default described in clauses (a)(iii), (a)(iv), (a)(v) or (a)(vi) of Section 6.01 of the Base Indenture, all affected series voting together as a single class) shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity and the Trustee shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity and the Trustee shall not have received from the holders of a majority in principal amount of the Notes at the time Outstanding (voting as provided in Section 6.04(b) of the Base Indenture) a direction inconsistent with such request. The foregoing shall not apply to any suit instituted by the holder of this Note for the enforcement of any payment of principal hereof or any interest on or after the respective due dates expressed herein.

As provided in the Indenture and subject to certain limitations therein set forth, this Note is transferable by the registered holder hereof on the Security Register of the Issuer, upon surrender of this Note for registration of transfer at the office or agency of the Issuer in the Borough of Manhattan, the City and State of New York accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer or the Trustee duly executed by the registered holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of authorized denominations and for the same aggregate principal amount and series will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto.

Prior to due presentment for registration of transfer of this Note, the Issuer, the Trustee, any paying agent and any Security Registrar may deem and treat the registered holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon and for all other purposes, and neither the Issuer nor the Trustee nor any paying agent nor any Note Registrar shall be affected by any notice to the contrary.

No recourse shall be had for the payment of the principal of or the interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past, present or future, as such, of the Issuer or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

The Notes are issuable only in registered form without coupons in authorized denominations. As provided in the Indenture and subject to certain limitations herein and therein set forth, Notes so issued are exchangeable for a like aggregate principal amount of Notes of a different authorized denomination, as requested by the holder surrendering the same.

All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

A-11

THE INDENTURE AND THE NOTES INCLUDING THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused “CUSIP” numbers to be printed on the Notes as a convenience to the holders of the Notes. No representation is made as to the correctness or accuracy of such CUSIP numbers as printed on the Notes, and reliance may be placed only on the other identification numbers printed hereon.

Unless the certificate of authentication hereon has been executed by or on behalf of the Trustee by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purposes.

c. Annual Bonus: You are eligible for an annual bonus on the terms set forth on Exhibit A. Bonus awards are discretionary and may be paid in the form of cash, deferred cash or Marsh & McLennan Companies stock units, or a combination thereof. Except as provided in this paragraph and in Section 3(a), to qualify for an annual bonus, you must remain continuously and actively employed by the Company, without having tendered a notice of resignation, through the date of the bonus payment, in accordance with the terms and conditions of the award. The annual bonus shall be paid no later than March 15 of the year following the year for which such bonus is earned. In the event of your Permanent Disability (as defined below) or death, the Company shall pay you (or your estate in the case of death) a prorated target annual bonus for the year in which your termination occurs based on the portion of the year elapsed as of the date of your termination. Any such bonus amount shall be paid within 30 days of your death. In the event of your Permanent Disability, your prorated annual bonus payment is conditioned upon, and subject to, your execution and delivery to the Company within 30 days of the date of such event a valid confidential waiver and release of claims agreement (including restrictive covenants) in a form satisfactory to the Company (the “Release”) and such Release has become irrevocable as provided therein (the “Release Effective Date”). Payment of any such annual bonus amount shall then be paid within 30 days following the Release Effective Date, but in no event later than March 15 of the year following the year for which such bonus is earned.

As used in this letter agreement, “Permanent Disability” will be deemed to occur when it is determined (by Marsh & McLennan Companies’ disability carrier for the primary long-term disability plan or program applicable to you because of your employment with the Company) that you are unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months.

d. Annual Long-Term Incentive Compensation: You are eligible to participate in Marsh & McLennan Companies’ long-term incentive program with a target long-term incentive compensation award as set forth on Exhibit A. Long-term incentive awards are discretionary and are governed by terms and conditions approved by the Compensation Committee of the Marsh & McLennan Companies Board of Directors (“Compensation Committee”) as set forth in the award agreement and in Marsh & McLennan Companies’ 2011 Incentive and Stock Award Plan (or other plan under which the long-term incentive award is granted). In accordance with Company practice, you may be required to enter into a “Restrictive Covenants Agreement” in connection with long-term incentive awards.

e. Benefit Programs: You and your eligible family members will continue to have the opportunity to participate in the employee benefit plans, policies and programs provided by Marsh & McLennan Companies, on such terms and conditions as are generally provided to similarly situated employees of the Company. These plans may include retirement, savings, medical, life, disability, and other insurance programs as well as an array of work/life effectiveness policies and programs. Please be aware that nothing in this letter agreement shall limit Marsh & McLennan Companies’ ability to change, modify, cancel or amend any such policies or plans. In addition, you will continue to be eligible to participate in the Marsh & McLennan Companies Executive Financial Services Program, as in effect from time to time.

Exhibit 10.2

NON-COMPETITION AND NON-SOLICITATION AGREEMENT

AGREEMENT, dated as of November 21, 2013, between Marsh & McLennan Companies, Inc. (”MMC”) and Peter J. Beshar, an employee of the Company (“Executive”). The terms of this Agreement are effective as of November 21, 2013.

RECITALS:

This Agreement is entered into in consideration of the Executive’s continued employment by the Company as Executive Vice President and General Counsel, the Company’s execution of the November 21, 2013 Letter Agreement regarding his terms of employment, Executive’s eligibility for a discretionary bonus and other compensation as an employee of the Company, and Executive’s access to confidential information and trade secrets belonging to the Company. For the purposes of this Agreement, the term “Company” means MMCand/or any corporation, partnership, joint venture, limited liability company, or other entity in which MMC has a 10% or greater direct or indirect interest.

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 a senior executive and member of MMC’s Executive Committee, 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 concepts and structures, 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 or planned by the Company to serve such clients, 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 and officers, 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's clients or prospective clients to be confidential, sensitive, proprietary or a trade secret or is not readily available to the public; or (vii) intellectual property, including inventions and

Page 2

copyrightable works. Confidential Information and Trade Secrets have actual or potential value because they are not generally known or available to the general public, but have been developed, compiled or acquired by the Company at its effort and expense and through the use of the Company’s resources. Confidential Information and Trade Secrets can 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 highly competitive businesses 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 effort and expense and through the use of the Company’s resources. 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 and loss of goodwill.

(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, which for the purposes of this Agreement, including such trade secret or proprietary or confidential information of any client, prospective client or other entity to which the Company owes an obligation not to disclose such information, which Executive acquires during Executive’s employment with the Company, 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 affiliate; (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 by any administrative or legislative body (including a committee thereof) with apparent jurisdiction to order Executive to divulge, disclose or make accessible such information (but only to the extent required by such requirement or order); or (iii) as to such confidential information that becomes generally known to the public or trade without the violation of this Agreement by Executive or by others under a duty of confidentiality to the Company.

(d)    Immediately upon the termination of employment with the Company for any reason or no 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, hard drives, 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 will cooperate with the Company in arranging to remove any electronic copies of such information from personal digital storage devices which Executive uses; 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 employee of the Company.

2.    Assignment of Rights to Intellectual Property; Ownership of Copyrightable Works

(a)    Executive agrees to assign and hereby does assign to the Company all Executive’s present and future right, title and interest in and to any intellectual property conceived, discovered, reduced to practice and/or made by Executive during the period of time that Executive is employed by the Company (whether before, on or after the date of this Agreement), whether such intellectual property was conceived, discovered and/or reduced to practice and/or made by Executive solely or jointly with others, on or off the premises of the Company’s business, or during or after working hours, if such intellectual property: (i) was conceived, discovered, reduced to practice and/or made with the Company’s facilities, equipment, supplies, confidential information, trade secrets or intellectual property; or (ii) relates to the Company’s current, or demonstrably anticipated or potential business activities, work or research; or (iii) results from work done or to be done by Executive or under Executive’s direction, alone or jointly, for the Company (“Intellectual Property”). Executive further acknowledges and agrees that such Intellectual Property as referred to herein belongs to the Company and that the Company may, in its sole discretion, keep such Intellectual Property and/or processes pertaining thereto, whether patentable or copyrightable or not, as trade secrets and make all decisions regarding whether and how to use such Intellectual Property and/or processes. Executive further agrees not to use or seek any commercial exploitation of or otherwise use any Intellectual Property transferred to the Company or required to be assigned under this Agreement for personal use.

(b)    Executive acknowledges, agrees and intends that all copyrightable works Executive creates during the period of time that Executive is employed by the Company (whether before, on or after the date of this Agreement) and within the scope of Executive’s employment shall be considered to be “works made for hire” as defined under the U.S. Copyright Act, 17 U.S.C. §§ 101 etseq. (“Copyrightable Works”). Executive also acknowledges, agrees and intends that the Company will be deemed the author of all such works made for hire and the owner of all of the rights comprised in the copyright of such works. To the extent that any Copyrightable Works Executive creates within the scope of Executive’s employment or using the resources of the Company do not fully qualify as works made for hire, Executive agrees to assign and hereby does assign all such Copyrightable Works to the Company, including the right to sue for past, present, or future infringement.

(c)    Executive agrees to: (i) promptly disclose such Intellectual Property and Copyrightable Works to the Company; (ii) assign to the Company, without additional compensation, the entire rights to Intellectual Property and Copyrightable Works for the United States and all foreign countries; (iii) execute all documents, certifications, and all other papers and do all acts necessary to carry out the above, including enabling the Company to file and prosecute applications for, acquire, ascertain and enforce in all countries, letters patent, trademark registrations and/or copyrights covering or otherwise relating to Intellectual Property and Copyrightable Works and to enable the Company to protect its proprietary interests therein; and (iv) give testimony in any action or proceeding to enforce rights in the Intellectual Property and Copyrightable Works.

(d)    In the event the Company is unable for any reason, after reasonable effort, to secure Executive’s signature on any document needed in connection with the actions specified in this Section 2, Executive hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Executive’s agent and attorney in fact, to act for and on Executive’s behalf to execute, verify and file any such documents and to do all other lawfully permitted acts to further the purposes of the preceding paragraph thereon with the same legal force and effect as if executed by Executive. Executive hereby assigns to the Company any and all claims, of any

Page 4

nature whatsoever, which Executive now or may hereafter have for infringement of any proprietary rights assigned or transferred hereunder to the Company.

(e)    Executive understands and agrees: (i) no license or conveyance of any rights or warranty to Executive is granted or implied by the Company furnishing or disclosing any Intellectual Property or Copyrightable Works to Executive; and (ii) the Company shall retain whatever ownership and other proprietary rights it otherwise has in all Intellectual Property and Copyrightable Works.

3.    Non-Competition

(a)    Executive acknowledges and agrees that the Company is engaged in highly competitive businesses and that by virtue of Executive’s position and responsibilities with the Company and Executive’s access to 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 and during the twelve (12) month period following the cessation of Executive’s employment with the Company, 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 engage in any activity - whether as an employee, consultant, principal, member, agent, officer, director, partner or shareholder (except as a less than 1% shareholder of a publicly traded company) - that is competitive with any business of the Company and that is conducted by the Company as of the date of the termination of the Executive’s employment. For purposes of this Agreement, the Company’s “business” means the provision of services and/or products of the type provided by the Company including but not limited to risk management, risk consulting, insurance broking, alternative risk financing, and insurance program management services; reinsurance broking and consulting, and risk assessment analytics; talent, health, benefits, retirement and investment consulting and services; and management and economic consulting. 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. The practice of law by the Executive following his termination of employment with the Company will not be considered an activity that is competitive with the Company. This provision will not prohibit the Executive from being employed by an insurance or reinsurance carrier that is not engaged in activity that is competitive with any business of the Company.

4.    Non-Solicitation/Non-Servicing of Clients

(a)Executive acknowledges and agrees that solely by reason of employment by the Company, Executive has and will come into contact with and develop and maintain relationships with a significant number of the Company’s clients and prospective clients and has and will 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, 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 or prospective 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; (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

Page 5

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 4(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 4, 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 4, 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.

5.    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 and during the twelve (12) month period following the cessation of Executive’s employment with the Company or any affiliate, 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 or servicing business or about whom Executive obtained Confidential Information and Trade Secrets, to leave employment with the Company.

6.    Enforcement

(a)    Executive acknowledges and agrees that the covenants contained in Sections 1, 2, 3, 4 and 5 of this Agreement are reasonable and necessary to protect the Confidential Information and Trade Secrets, business 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 or cause undue hardship and that the covenants contained in Sections 1, 2, 3, 4 and 5 are reasonable in view of the benefits and consideration Executive has received or will receive from the Company.

(b)    In recognition of the fact that irreparable harm will result to the Company in the event of any breach or anticipatory breach of Section 1, 2, 3, 4 or 5 of this Agreement by Executive, or Executive’s claim in a declaratory judgment action that all or part of this Agreement is unenforceable, and that money damages may not provide adequate relief, 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 other equitable relief, 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 contained in Section 4 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 4 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 Executive’s 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 Executive’s 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 3, 4 and 5 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 period equal to the duration of any violations thereof by Executive.

7.    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.

8.    Miscellaneous

(a)    Governing Law; Choice of Forum. The parties acknowledge that MMC and its operating companies are headquartered in New York, that senior members of the leadership team of the Company are based in New York, and that breach of this Agreement will cause injury in New York. 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 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

Page 7

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; Agreement to Enter into Additional Agreements. 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. Should Executive move to a different state or jurisdiction while employed by the Company or upon written request of the Company, Executive agrees to sign, without further consideration, upon direction by the Company, such further writings to effectuate the provisions of this Agreement as necessary to comply with applicable law. Executive’s failure to sign such additional agreements shall constitute a breach of 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 affiliates, successors and assigns, and shall inure to the benefit of the Company and its affiliates, successors and assigns. This Agreement may not be assigned by Executive. This Agreement may be enforced by the Company and its affiliates, successors and assigns.

(f)    Other Agreements. This Agreement contains the entire agreement between Executive and the Company with respect to non-competition and non-solicitation restrictions, and supersedes and terminates any and all previous such agreements and understandings between Executive and the Company, whether written or oral, with respect to noncompetition or nonsolicitation restrictions. If the non-competition and non-solicitation restrictions contained in this Agreement are ruled invalid for any reason by a court of competent jurisdiction, then the non-competition and non-solicitation restrictions contained in any and all previous agreements shall be revived. 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.

An award (“Award”) has been granted to you under the Marsh & McLennan Companies, Inc. 2011 Incentive and Stock Award Plan (the “Plan”), subject to your acceptance as described in Section II.A.2. The Award types, the number of shares of Marsh & McLennan Companies, Inc. (“Marsh & McLennan Companies”) common stock covered by the Award, instructions on how to accept or decline the Award and the deadline for accepting the Award are specified in materials provided to you by Global & Executive Compensation (“Grant Documentation”). The Award is also subject to the terms and conditions set forth herein (the “Terms and Conditions”). For employees outside the United States, the Awards are subject to additional terms and conditions as set forth in the country-specific notices (the “Country-Specific Notices”). The Prospectus dated [DATE], also describes important information about the Plan. The Terms and Conditions, the Country-Specific Notices (if applicable) and the Plan will be referred to herein as the “Award Documentation”. As used herein, “Common Stock” means common stock of Marsh & McLennan Companies.

Capitalized terms in these Terms and Conditions are defined in Section V.

II.    AWARDS

A. General.

1. Grant of Award and Award Types. The types of awards that may have been granted to you under the Plan are described below. The description of a type of award in these Terms and Conditions that is not part of the Award does not give or imply any right to such type of award.

2. Award Acceptance. The grant of this Award is contingent upon your acceptance, by the date and in the manner specified in the Grant Documentation, of these Terms and Conditions, the Country-Specific Notices (if applicable) and Restrictive Covenants Agreement as described in Section II.A.4. If you decline the Award or if you do not accept the Award and any applicable documents described in the preceding sentence by the date and in the manner specified in the Grant Documentation, then the Award will be cancelled as of the grant date of the Award.

3. Rights of Award Holders. Unless and until the vesting conditions of the Award have been satisfied and cash or shares of Common Stock, as applicable, have been delivered to you in accordance with the Award Documentation, you have only the rights of a general unsecured creditor of Marsh & McLennan Companies. Unless and until shares of Common Stock have been delivered to you, you have none of the rights of ownership to such shares (e.g., units cannot be used as payment for stock option exercises; units may not be transferred or assigned; units have no voting rights).

4. Restrictive Covenants Agreement. As described in Section II.A.2., a Restrictive Covenants Agreement (“Restrictive Covenants Agreement”) in a form determined by Marsh & McLennan Companies must be in place in order to accept the Award, you must execute or reaffirm, as determined by Marsh & McLennan Companies in its sole discretion, the Restrictive Covenants Agreement in order for the Award to vest pursuant to certain employment events

1

2015 LTI Combined Terms & Conditions

as described in Section III., and you must further execute or reaffirm, as determined by Marsh & McLennan Companies in its sole discretion, and be in compliance with the Restrictive Covenants Agreement in order for the Award to become distributable to you or to exercise an Option whether or not you are employed by the Company (as defined in Section V.D.) at that time. Failure to timely execute the Restrictive Covenants Agreement by the date specified in the Grant Documentation or failure to timely execute or reaffirm and comply with the Restrictive Covenants Agreement as described in Section III.I.1. or 2., as applicable, will result in cancellation or forfeiture of any rights, title and interest in and to the Award, without any liability to the Company.

B. Stock Units.

1. General. A restricted stock unit (“Stock Unit”) represents an unfunded and unsecured promise to deliver (or cause to be delivered) to you, subject to the terms of the Award Documentation, one share of Common Stock after vesting.

2. Vesting. Subject to your continued employment, 33-1/3% of the Stock Units will vest on [DATE] of [YEAR], [YEAR] and [YEAR]. Each date on which a Stock Unit is scheduled to vest pursuant to this Section II.B.2. is a “Stock Unit Scheduled Vesting Date.” In the event of your termination of employment, the occurrence of your Permanent Disability (as defined in Section V.H.) or the occurrence of a “Change in Control” (as defined in the Plan) prior to a Stock Unit Scheduled Vesting Date, your right to any Stock Units that are unvested immediately prior to your termination of employment or occurrence of your Permanent Disability, as applicable, will be determined in accordance with Section III. or Section IV., as applicable. For the avoidance of doubt, the date of your termination of employment for purposes of determining vesting under this Section II.B.2. will be determined in accordance with Section III.H.

3. Dividend Equivalents. For each outstanding Stock Unit covered by the Award, an amount equal to the dividend payment (if any) made in respect of one share of Common Stock (a “Dividend Equivalent”) will accrue in U.S. dollars on each dividend record date that occurs on or after the grant date of the Award while the Award is outstanding, with no interest paid on such amounts. Accrued Dividend Equivalents will vest when the Stock Units in respect of which such Dividend Equivalents were accrued vest. Accrued Dividend Equivalents will not be paid, and no further Dividend Equivalents will accrue, on Stock Units that do not vest or are cancelled or forfeited.

4. Delivery.

a. Shares of Common Stock deliverable in respect of the Stock Units covered by the Award shall be delivered to you as soon as practicable following the Stock Unit Scheduled Vesting Date, and in no event later than 60 days following the Stock Unit Scheduled Vesting Date, except as otherwise provided in Sections III., IV., and VI.B.

b. The value of vested Dividend Equivalents will be delivered to you in cash as soon as practicable after delivery of the shares of Common Stock described

2

2015 LTI Combined Terms & Conditions

in II.B.4.a above, and in no event later than 60 days following the Stock Unit Scheduled Vesting Date, except as otherwise provided in Sections III., IV., and VI.B.

c. The delivery of shares of Common Stock and/or cash or other property that may be deliverable under these Terms and Conditions, is conditioned on the satisfaction or withholding of any applicable tax obligations, as described in Section II.E.

d. Any shares of Common Stock and/or cash or other property that may be deliverable following your death shall be delivered to the person or persons to whom your rights pass by will or the law of descent and distribution, and such delivery shall completely discharge Marsh & McLennan Companies and any of its subsidiaries or affiliate’s obligations under the Award.

e. Notwithstanding the foregoing, additional delivery rules for certain Award recipients subject to U.S. federal income tax (whether or not the recipient is a U.S. citizen or employed in the U.S.) are reflected in Section III.K.

C. Performance Stock Units.

1. General. A performance stock unit (“PSU”) represents an unfunded and unsecured promise to deliver (or cause to be delivered) to you, subject to the terms of the Award Documentation, a minimum of zero (0) and up to a maximum of two (2) shares of Common Stock after vesting, depending on the achievement, as determined by the Compensation Committee of the Board of Directors of Marsh & McLennan Companies (the “Committee”), of the financial performance objectives established by the Committee for the Performance Period (as defined in Section V.G.). In the event of your termination of employment or occurrence of your Permanent Disability prior to the PSU Scheduled Vesting Date (defined below), the number of shares of Common Stock deliverable in respect of a PSU shall be determined as provided in Sections III. and IV.A.3.

2. Vesting. Subject to your continued employment, the PSUs are scheduled to vest on [DATE] (the “PSU Scheduled Vesting Date”). In the event of your termination of employment, the occurrence of your Permanent Disability or a Change in Control prior to the PSU Scheduled Vesting Date, your right to the PSUs will be determined in accordance with Section III. or Section IV., as applicable. For the avoidance of doubt, the date of your termination of employment for purposes of this Section II.C.2. will be determined in accordance with Section III.H.

3. Dividend Equivalents. Dividend Equivalents (if any) will be paid for each share of Common Stock that is determined under Section II.C.1. to be delivered in respect of a vested PSU. Dividend Equivalents will be calculated as if such share that is to be delivered in respect of a vested PSU was outstanding as of each dividend record date that occurs on or after the grant date of the Award while the Award is outstanding with no interest paid on such amounts. Dividend Equivalents will vest when the PSUs, in respect of which such Dividend

3

2015 LTI Combined Terms & Conditions

Equivalents were calculated, vest. Dividend Equivalents will not be paid on PSUs that do not vest or are cancelled or forfeited.

4. Delivery.

a. Shares of Common Stock deliverable, if any, in respect of the PSUs covered by the Award that vest on the PSU Scheduled Vesting Date shall be delivered to you as soon as practicable following the PSU Scheduled Vesting Date, and in no event later than 60 days following the PSU Scheduled Vesting Date, except as otherwise provided in Sections III., IV., and VI.B.

e. Notwithstanding the foregoing, additional delivery rules for certain Award recipients subject to U.S. federal income tax (whether or not the recipient is a U.S. citizen or employed in the U.S.) are reflected in Section III.K.

D. Options.

1. General. A stock option (“Option”), whether qualified or nonqualified, represents the right to purchase the number of shares of Common Stock specified in the Grant Documentation (the “Option Shares”) each at the exercise price specified in the Grant Documentation.

2. Vesting. Subject to your continued employment, 25% of the Option Shares covered by the Option will vest on each of the first four anniversaries of the grant date of the Award. Each date on which an Option Share covered by the Option is scheduled to vest is an “Option Scheduled Vesting Date.” In the event of your termination of employment or occurrence of your Permanent Disability prior to an Option Scheduled Vesting Date, your right to any Option Shares covered by the Option that are unvested immediately prior to your termination of employment or occurrence of your Permanent Disability, as applicable, will be determined in accordance with Section III. For the avoidance of doubt, the date of your termination of employment for purposes of this Section II.D.2. will be determined in accordance with Section III.H.

4

2015 LTI Combined Terms & Conditions

3. Term. Subject to your continued employment, the Option will expire on the day immediately preceding the tenth anniversary of the grant date of the Award (“Option Expiration Date”). If your employment terminates before the Option Expiration Date, your right to exercise any vested Option Shares covered by the Option will be determined in accordance with Section III.

4. Exercisability. The Option Shares covered by the Option will become exercisable when they vest. You are responsible for keeping track of exercise periods while actively employed and, if applicable, any post-termination exercise periods.

5. Method of Exercise of an Option.

a. General Procedures. An Option may be exercised by written notice to Marsh & McLennan Companies or an agent appointed by Marsh & McLennan Companies, in form and substance satisfactory to Marsh & McLennan Companies, which must state the election to exercise such Option, the number of Option Shares for which such Option is being exercised and such other representations and agreements as may be required pursuant to the provisions of the Award Documentation (the “Exercise Notice”). The Exercise Notice must be accompanied by (i) any required income tax forms and (ii) a reaffirmation of the Restrictive Covenants Agreement, unless (A) the Option is being exercised after your death in accordance with Section III. or (B) as otherwise determined by Marsh & McLennan Companies.

b. Payment of Exercise Price. Payment of the aggregate exercise price may be made with U.S. dollars or by tendering shares of Common Stock (including shares of Common Stock acquired from a stock option exercise or a stock unit award vesting).

c. Distribution of Option Shares. The shares of Common Stock from the Option exercise will be distributed as specified in the Exercise Notice, after you have satisfied applicable tax obligations, as described in Section II.E., and fees.

E. Satisfaction of Tax Obligations.

1. Personal Tax Advisor. Neither the Company nor any Company employee is authorized to provide personal tax advice to you. It is recommended that you consult with your personal tax advisor for more detailed information regarding the tax treatment of the Award, especially before making any decisions that rely on that tax treatment.

2. U.S. Employees.

a. Stock Units, Performance Stock Units and Dividend Equivalents. Applicable employment taxes are required by law to be withheld when a Stock Unit, PSU or Dividend Equivalent vests, or, if later, when the number of shares of Common Stock deliverable in respect of a PSU (or the amount of cash payable in respect of a Dividend Equivalent corresponding to a PSU) is

5

2015 LTI Combined Terms & Conditions

determined. Applicable income taxes are required by law to be withheld when shares of Common Stock in respect of Stock Units, PSUs or cash in respect of Dividend Equivalents are delivered to you. A sufficient number of whole shares of Common Stock, cash or other property, as applicable, will be retained by Marsh & McLennan Companies to satisfy the tax-withholding obligation.

b. Options. Applicable taxes (including employment taxes) are required by law to be withheld when a nonqualified Option is exercised.

3. Non-U.S. Employees.

a. Stock Units, Performance Stock Units and Dividend Equivalents. In most countries, the value of a Stock Unit, PSU or Dividend Equivalent is generally not taxable on the grant date. If the value of the Stock Unit, PSU or Dividend Equivalent is not taxable on the grant date, it will, in most countries, be taxed at a later time, for example, upon delivery of a share of Common Stock in respect of the Stock Unit or PSU that vests, and/or the subsequent sale of the share of Common Stock received in connection with the vesting of the Stock Unit or PSU, or upon delivery of cash in respect of a Dividend Equivalent.

b. Options. In most countries, the value of an Option is generally not taxable on the grant date. If the value of the Option is not taxable on the grant date, it will, in most countries, be taxed at a later time, for example, upon exercise of the Option and delivery of shares of Common Stock in respect of the Option, and/or the subsequent sale of the shares of Common Stock.

c. Withholding. Marsh & McLennan Companies and/or your employer shall have the power and the right to deduct and withhold from the Award and other compensation or to require you to remit to Marsh & McLennan Companies and/or to your employer, an amount sufficient to satisfy any taxes that Marsh & McLennan Companies expects to be payable under the laws of any country, state, province, city or other jurisdiction, including but not limited to income taxes, payroll taxes, fringe benefits, payment on account, capital gain taxes, transfer taxes, social security contributions and National Insurance Contributions with respect to the Award, and any and all associated tax events derived therefrom. If applicable, Marsh & McLennan Companies and/or your employer may retain and sell a sufficient number of whole shares of Common Stock distributable in respect of the Award for this purpose.

B. Additional Provisions—Outside of the United States

1. Changes to Delivery. In the event that Marsh & McLennan Companies considers that due to legal, regulatory or tax issues the normal delivery of an Award (as described in these Terms and Conditions) to a participant outside the United States would not be appropriate, then Marsh & McLennan Companies may, in its sole discretion, determine how and when the value of the Award will be delivered. Without limitation, this may include making any payments due under the Award in cash instead of shares of Common Stock, or in shares of Common Stock instead of cash, in an amount equivalent to the value of the Award on the date of exercise (for Options) or vesting after payment of applicable taxes and fees and any exercise price or, delivering or paying out the Award as soon as practicable following a termination of employment.

2. Amendment and Modification. The Committee may modify the terms of any Award under the Plan granted to you in any manner deemed by the Committee to be necessary or appropriate in order for such Award to conform to laws, regulations and customs of the country (other than the United States) in which you are then resident or primarily employed or were resident or primarily employed at the time of grant or during the term of the Award, or so that the value and other benefits of the Award to you, as affected by non-U.S. tax laws and other restrictions applicable as a result of your residence or employment outside of the United States, shall be comparable to the value of such an Award to an individual who is resident or primarily employed in the United States.

I. BACKGROUND

An award (“Award”) has been granted to you under the Marsh & McLennan Companies, Inc. 2011 Incentive and Stock Award Plan (the “Plan”), subject to your acceptance as described in Section II.A.1. The Award type, the number of shares of Marsh & McLennan Companies, Inc. (“Marsh & McLennan Companies”) common stock covered by the Award, instructions on how to accept or decline the Award and the deadline for accepting the Award are specified in materials provided to you by Global & Executive Compensation (“Grant Documentation”). The Award is also subject to the terms and conditions set forth herein (the “Terms and Conditions”). For employees outside the United States, the Award is subject to additional terms and conditions as set forth in the country-specific notices (the “Country-Specific Notices”). The Prospectus dated [DATE] also describes important information about the Plan. The Terms and Conditions, the Country-Specific Notices (if applicable), and the Plan will be referred to herein as the “Award Documentation”. As used herein, “Common Stock” means common stock of Marsh & McLennan Companies.

Capitalized terms in these Terms and Conditions are defined in Section V.

II. AWARDS

A. General.

1. Award Acceptance. The grant of this Award is contingent upon your acceptance, by the date and in the manner specified in the Grant Documentation, of these Terms and Conditions, the Country-Specific Notices (if applicable) and Restrictive Covenants Agreement as described in Section II.A.3. If you decline the Award or if you do not accept the Award and any applicable documents described in the preceding sentence by the date and in the manner specified in the Grant Documentation, then the Award will be cancelled as of the grant date of the Award.

2. Rights of Award Holders. Unless and until the vesting conditions of the Award have been satisfied and cash or shares of Common Stock, as applicable, have been delivered to you in accordance with the Award Documentation, you have only the rights of a general unsecured creditor of Marsh & McLennan Companies. Unless and until shares of Common Stock have been delivered to you, you have none of the rights of ownership to such shares (e.g., units cannot be used as payment for stock option exercises; units may not be transferred or assigned; units have no voting rights).

3. Restrictive Covenants Agreement. As described in Section II.A.1., a Restrictive Covenants Agreement (“Restrictive Covenants Agreement”) in a form determined by Marsh & McLennan Companies must be in place in order to accept the Award and you must execute or reaffirm, as determined by Marsh & McLennan Companies, in its sole discretion, the Restrictive Covenants Agreement in order for the Award to vest pursuant to certain employment events as described in Section III. Failure to timely execute the Restrictive Covenants Agreement by the date specified in the Grant Documentation or failure to timely execute or reaffirm and comply with the Restrictive Covenants Agreement as described in Section III.F.1. or 2., as applicable, will result in cancellation or forfeiture of any rights, title and interest in and to the Award, without any liability to the Company (as defined in Section V.B.).

2

B. Stock Units.

1. General. A deferred stock unit (“Stock Unit”) represents an unfunded and unsecured promise to deliver (or cause to be delivered) to you, subject to the terms of the Award Documentation, one share of Common Stock after vesting.

2. Vesting. Subject to your continued employment, [PERCENTAGE] of the Stock Units will vest on the 15th of the month in which the [VESTING DATE(S)] of the grant date of the Award occurs. [Each] date on which a Stock Unit is scheduled to vest pursuant to this Section II.B.2. is [a] “Scheduled Vesting Date.” In the event of your termination of employment or the occurrence of your Permanent Disability (as defined in Section V.D.) prior to [a] Scheduled Vesting Date, your right to any Stock Units that are unvested immediately prior to your termination of employment or occurrence of your Permanent Disability, as applicable, will be determined in accordance with Section III. below. For the avoidance of doubt, the date of your termination of employment for purposes of determining vesting under this Section II.B.2. will be determined in accordance with Section III.E.

3. Dividend Equivalents. For each outstanding Stock Unit covered by the Award, an amount equal to the dividend payment (if any) made in respect of one share of Common Stock (a “Dividend Equivalent”) will accrue in U.S. dollars on each dividend record date that occurs on or after the grant date of the Award while the Award is outstanding, with no interest paid on such amounts. Accrued Dividend Equivalents will vest when the Stock Units in respect of which such Dividend Equivalents were accrued vest. Accrued Dividend Equivalents will not be paid, and no further Dividend Equivalents will accrue, on Stock Units that do not vest or are cancelled or forfeited.

4. Delivery.

a. Shares of Common Stock deliverable in respect of the Stock Units covered by the Award shall be delivered to you as soon as practicable after vesting, and in no event later than 60 days after vesting.

b. The value of vested Dividend Equivalents will be delivered to you in cash as soon as practicable after vesting and in no event later than 60 days after vesting.

c. The delivery of shares of Common Stock and/or cash or other property that may be deliverable under these Terms and Conditions, is conditioned on the satisfaction or withholding of any applicable tax obligations, as described in Section II.C.

d. Any shares of Common Stock and/or cash or other property that may be deliverable following your death shall be delivered to the person or persons to whom your rights pass by will or the law of descent and distribution, and such delivery shall completely discharge Marsh & McLennan Companies and any of its subsidiaries’ or affiliates’ obligations under the Award.

e. Notwithstanding the foregoing, additional delivery rules for certain Award recipients subject to U.S. federal income tax (whether or not the recipient is a U.S. citizen or employed in the U.S.) are reflected in Section III.H.

3

C. Satisfaction of Tax Obligations.

1. Personal Tax Advisor. Neither the Company nor any Company employee is authorized to provide personal tax advice to you. It is recommended that you consult with your personal tax advisor for more detailed information regarding the tax treatment of the Award, especially before making any decisions that rely on that tax treatment.

2. U.S. Employees. Applicable employment taxes are required by law to be withheld when a Stock Unit or Dividend Equivalent vests. Applicable income taxes are required by law to be withheld when shares of Common Stock in respect of Stock Units or cash in respect of Dividend Equivalents are delivered to you. A sufficient number of whole shares of Common Stock, cash or other property, as applicable, will be retained by Marsh & McLennan Companies to satisfy the tax-withholding obligation.

3. Non-U.S. Employees.

a. Stock Units and Dividend Equivalents. In most countries, the value of a Stock Unit or Dividend Equivalent is generally not taxable on the grant date. If the value of the Stock Unit or Dividend Equivalent is not taxable on the grant date, it will, in most countries, be taxed at a later time, for example, upon delivery of a share of Common Stock in respect of the Stock Unit that vests, and/or the subsequent sale of the share of Common Stock received in connection with the vesting of the Stock Unit or upon delivery of cash in respect of a Dividend Equivalent.

b. Withholding. Marsh & McLennan Companies and/or your employer shall have the power and the right to deduct and withhold from the Award and other compensation or to require you to remit to Marsh & McLennan Companies and/or to your employer, an amount sufficient to satisfy any taxes that Marsh & McLennan Companies expects to be payable under the laws of any country, state, province, city or other jurisdiction, including but not limited to income taxes, payroll taxes, fringe benefits, payment on account, capital gain taxes, transfer taxes, social security contributions, and National Insurance Contributions with respect to the Award, and any and all associated tax events derived therefrom. If applicable, Marsh & McLennan Companies and/or your employer may retain and sell a sufficient number of whole shares of Common Stock distributable in respect of the Award for this purpose.

III. EMPLOYMENT EVENTS

A. Death. In the event your employment is terminated because of your death, the unvested Stock Units will fully vest at such termination of employment and will be distributed as described in Section II.B.4.

B. Permanent Disability. Upon the occurrence of your Permanent Disability, the unvested Stock Units will fully vest and will be distributed as described in Section II.B.4., provided that you satisfy the conditions to vesting described in Section III.F.1.

4

C. Termination by the Company Other Than for Cause.

1. General. Except as otherwise provided in Section IV., in the event the Company, in its sole discretion, determines that your employment is terminated by the Company other than for Cause (as defined in Section V.A.), the unvested Stock Units will vest at such termination of employment on a pro-rata basis as described in Section III.G. and will be distributed as described in Section II.B.4., provided that you satisfy the conditions to vesting described in Section III.F.2.

2. Important Notes.

a. Sale of Business Unit. For purposes of this Award, in the event of a sale or similar transaction involving the business unit for which you work (“Employing Company”) as a result of which the Employing Company ceases to be a subsidiary or affiliate of Marsh & McLennan Companies, your employment will be deemed terminated by the Company other than for Cause, even if your employment with the Employing Company continues after the sale or similar transaction.

b. Constructive Discharge. The Award will not vest, whether on a pro-rata or full basis, upon a constructive discharge, including if any court or regulatory agency retroactively concludes or interprets events to have constituted a constructive discharge.

D. All Other Terminations. For all other terminations of employment not described in Sections III.A. through C. or Section IV. (including, but not limited to, a termination by the Company for Cause or a resignation by you of your employment with the Company), any rights, title and interest in and to any remaining unvested portion of the Award shall be cancelled as of the date your employment is treated as having terminated as described in Section III.E.

E. Date of Termination of Employment.

1. If Section III.E.2. does not apply to you, then for purposes of determining vesting under Section II.B.2. and the number of unvested Stock Units that vest on a pro-rata basis as described in Section III.G., your employment will be treated as having terminated on your last day of employment with the Company.

2. If you are a Guy Carpenter employee in the United States who is obligated to provide the Company at least 60 days advance written notice of your intention to terminate your employment for any reason, then, if your employment terminates pursuant to Section III.D., your employment will be treated as having terminated for purposes of determining vesting under Section II.B.2. on the date that is 60 days prior to your last day of employment with the Company. Notwithstanding the foregoing, if your employment is terminated after providing notice pursuant to the preceding sentence but prior to the intended termination date provided in such notice (i) by the Company other than for Cause or (ii) pursuant to a written agreement, the terms of which provide that your termination of employment has been by mutual agreement between you and the Company, then the Company may, in its sole discretion, determine that for purposes of determining vesting under Section II.B.2. your employment will be treated as having terminated on a date later than the date that is 60 days prior to your last day of employment with the Company, but in no event later than your last day of employment with the Company.

5

F. Conditions to Vesting of Award Prior to [a] Scheduled Vesting Date.

1. Restrictive Covenants Agreement. In the event of the occurrence of your Permanent Disability as described in Section III.B., you will be required to execute or reaffirm, as determined by Marsh & McLennan Companies in its sole discretion, and return to Marsh & McLennan Companies (or an agent appointed by Marsh & McLennan Companies) a Restrictive Covenants Agreement. Failure to (a) execute or reaffirm such an agreement by the date specified by the Company, which shall be in no event later than 60 days following the occurrence of your Permanent Disability as described in Section III.B., or (b) comply with the Restrictive Covenants Agreement, will result in the cancellation or forfeiture of any rights, title and interest in and to the Award without any liability to the Company.

2. Waiver and Release and Restrictive Covenants Agreement. In the event of your termination of employment by the Company other than for Cause as described in Section III.C., you will be required to (i) execute or reaffirm, as determined by Marsh & McLennan Companies in its sole discretion, and return to Marsh & McLennan Companies (or an agent appointed by Marsh & McLennan Companies) a Restrictive Covenants Agreement and (ii) execute and not revoke a waiver and release agreement, if provided to you by the Company at the time of your termination of employment. Failure to meet these requirements by the date specified by the Company, which shall be in no event later than 60 days following your termination of employment, or failure to comply with the waiver and release agreement or the Restrictive Covenants Agreement, as applicable, will result in the cancellation or forfeiture of any rights, title and interest in and to the Award without any liability to the Company.

G. Determination of Pro-Rata Vesting upon Termination of Employment.

The number of Stock Units that vests on a pro-rata basis upon your termination of employment will be determined using the following formula:

where

A =     the number of Stock Units covered by the Award;

B =    the number of days in the period beginning on the grant date of the Award and ending on the date of your termination of employment, as determined in accordance with Section III.E.1.;

C =    the number of days in the period beginning on the grant date of the Award and ending on the [last] Scheduled Vesting Date; and

H. Section 409A of the Code for Award Recipients Subject to U.S. Federal Income Tax (whether or not the recipient is a U.S. citizen or employed in the U.S.).

1. For Award recipients subject to U.S. federal income tax, notwithstanding any other provision herein, the Award may be subject to additional restrictions to ensure compliance with (or continued exemption from) the requirements of Section 409A of the Code (as defined in Section V.E.). The Compensation Committee of the Board of Directors of Marsh & McLennan Companies (the “Committee”) intends to administer the Award in accordance with Section 409A of the Code and reserves the right to make changes in the terms or operations of the Award (including changes that may have retroactive effect) deemed necessary or desirable to comply with Section 409A of the Code. This means, for example, that the timing of distributions may be different from those described in the Award Documentation that do not reflect Section 409A of the Code. If the Award is not in compliance with Section 409A of the Code, you may be subject to immediate taxation of all unpaid awards under the Plan that are subject to Section 409A of the Code at your regular federal income tax rate, plus a 20% additional tax, plus interest at the underpayment rate plus 1%, as well as any state and local taxes, penalties, additional taxes and interest, if applicable, imposed under any state tax law similar to Section 409A of the Code.

2. Notwithstanding any other provision herein, if any portion of the Award is determined to be nonqualified deferred compensation subject to Section 409A of the Code, any references to “termination of employment,” or “when you are no longer employed” in these Terms and Conditions shall have the following meaning:

Your "termination of employment" (or similar terms) shall occur when you have incurred a “separation from service” within the meaning of Section 409A of the Code and as further defined herein. Specifically, you will have incurred a “separation from service” when the level of services you provide to the Company in any capacity, including as an employee, director, independent contractor or consultant, does not exceed 20% of the average level of services that you provided to the Company in the preceding 36 months (or shorter period of service if, for example, your total service with the Company is less than 36 months), all as determined in accordance with Section 409A of the Code. In determining whether a “separation from service” has occurred, any period of up to six months during which you are on a bona fide leave of absence or up to 29 months during which you are absent from work due to a disability for which you are receiving Marsh & McLennan Companies long-term disability benefits will be ignored.

3. Notwithstanding any other provision herein, if at the time of your termination of employment you are a “specified employee” (as defined in Section 409A of the Code) no portion of the Award that is determined to be nonqualified deferred compensation subject to Section 409A of the Code shall be distributed until the first day of the seventh month after your termination of employment and any such distributions to which you would otherwise be entitled during the first six months following your termination of employment will be accumulated and paid without interest on the first day of the seventh month after your termination of employment. The provisions of this subparagraph will only apply if and to the extent required to avoid any “additional tax” under Section 409A of the Code.

7

4. Nothing in this Section III.H. is intended to nor does it guarantee that the Award will not be subject to “additional tax” or other adverse tax consequences under Section 409A of the Code or any similar state tax law.

IV. CHANGE IN CONTROL PROVISIONS

A. Upon the occurrence of a “Change in Control”, as defined in the Plan, the Award will continue to vest in accordance with the vesting schedule specified in Section II.B.2. and subject to earlier vesting or forfeiture pursuant to Section III., provided that the Award will become fully vested at your termination of employment by the Company other than for Cause, or by you for Good Reason (as defined in Section V.C.), during the 24-month period following such Change in Control and will be distributed as described in Section II.B.4., provided that you satisfy the conditions to vesting described in Section IV.B. Notwithstanding the foregoing, if the Award is not assumed, converted or replaced in connection with a Change in Control on an equivalent basis, the Award will fully vest immediately prior to the Change in Control and will be distributed as described in Section II.B.4.

B. As a condition to vesting of any unvested portion of the Award, in the event of your termination of employment by the Company other than for Cause or by you for Good Reason during the 24-month period following such Change in Control, you will be required to execute and not revoke a waiver and release agreement, if provided by the Company at the time of your termination of employment. Failure to meet these requirements by the date specified by the Company, which shall be in no event later than 60 days following your termination of employment, or failure to comply with the waiver and release agreement, if applicable, will result in the cancellation or forfeiture of any rights, title and interest in and to the Award.

A. “Cause” shall mean:

1. willful failure to substantially perform the duties consistent with your position which is not remedied within 30 days after receipt of written notice from the Company specifying such failure;

New Accounting Guidance

3 Months Ended

Mar. 31, 2015

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

New Accounting Guidance

New Accounting Guidance

In February 2015, the FASB issued new accounting guidance intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations and securitization structures. The guidance focuses on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. The guidance is effective for periods beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact of the adoption of the guidance on its financial condition and results of operations.

In January 2015, the FASB issued new accounting guidance that eliminated the concept of extraordinary items. The guidance is effective for annual periods beginning after December 15, 2015. The guidance may be adopted prospectively, or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided the guidance is applied from the beginning of the fiscal year of adoption. Adoption of the guidance is not expected to materially affect the Company's financial condition, results of operations or cash flows.

In June 2014, the FASB issued new accounting guidance to clarify the treatment of share-based payment awards that require a specific performance target to be achieved in order for employees to be eligible to vest in the awards which include terms that may provide that the performance conditions could be achieved after an employee completes the requisite service period. The guidance requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, a reporting entity should apply the existing guidance as it relates to awards with performance conditions that affect vesting. The guidance is effective for annual periods beginning after December 15, 2015. Early adoption is permitted. Adoption of the guidance is not expected to materially affect the Company's financial condition, results of operations or cash flows.

In May 2014, the FASB issued new accounting guidance to clarify the principles for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that principle, the entity should apply the following steps: identify the contract(s) with the customer, identify the performance obligations in the contract(s), determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when (or as) the entity satisfies a performance obligation. The guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. Entities are permitted to adopt the guidance under one of the following methods: retrospectively to each prior reporting period presented (with certain practical expedients allowed) or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application. If an entity elects this transition method, it must provide disclosures in reporting periods that include the date of initial application of the amount by which each financial statement line item is affected in the current reporting period by application of the guidance as compared to guidance that was in effect before the change, and an explanation for the reasons for significant changes. The Company is currently evaluating the impact of the adoption of the guidance on its financial condition and results of operations.

In April 2014, the FASB issued new accounting guidance which changes the criteria for reporting discontinued operations and enhances disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations, such as disposal of a major geographic area or a major line of business, should be presented as discontinued operations. Those strategic shifts should have a major impact on the organization's operations and financial results. In addition, the new guidance requires expanded disclosures about discontinued operations. The guidance is effective for fiscal years beginning on or after December 15, 2014. Adoption of the guidance did not affect the Company's financial condition, results of operations or cash flows.

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 considers numerous factors, which include that the fair value of each reporting unit exceeds its fair value by a substantial margin in its most recent estimate of reporting unit fair values, whether significant acquisitions or dispositions occurred which might alter the fair value of its reporting units, macroeconomic conditions and their potential impact on reporting unit fair values, actual performance compared with budget and prior projections used in its estimation of reporting unit fair values, industry and market conditions, and the year-over-year change in the Company’s share price. The Company completed its qualitative assessment in the third quarter of 2014 and concluded that a two-step goodwill impairment test was not required in 2014, 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:

March 31,
(In millions of dollars)	2015			2014
Balance as of January 1, as reported	$	7,241		$	6,893
Goodwill acquired	12			267
Other adjustments(a)	(93		)	(1		)
Balance at March 31,	$	7,160		$	7,159

^(a)  Primarily reflects the impact of foreign exchange in each period.

Goodwill allocable to the Company’s reportable segments at March 31, 2015 is as follows: Risk & Insurance Services, $5 billion and Consulting, $2.2 billion.

Amortized intangible assets consist of the cost of client lists, client relationships and trade names acquired. The gross cost and accumulated amortization are as follows:

	March 31, 2015						December 31, 2014
(In millions of dollars)	Gross Cost		Accumulated Amortization		Net Carrying Amount		Gross Cost		Accumulated Amortization		Net Carrying Amount

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 Financial Accounting Standards Board ("FASB"). The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy, for disclosure purposes, is determined based on the lowest level input that is significant to the fair value measurement. Assets and liabilities recorded in the consolidated balance sheets at fair value are categorized based on the inputs in the valuation techniques as follows:

Level 1. Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market (examples include active exchange-traded equity securities and money market mutual funds).

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 and 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.

Contingent 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 resulting 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 March 31, 2015 and December 31, 2014.

	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 accounts payable and accrued liabilities and other liabilities in the consolidated balance sheets.

During the three-month period ended March 31, 2015, there were no assets or liabilities that were transferred between any of the levels.

The table below sets forth a summary of the changes in fair value of the Company’s Level 3 liabilities as of March 31, 2015 and 2014 that represent contingent consideration related to acquisitions:

(In millions of dollars)	2015			2014
Balance at January 1,	$	207		$	104
Additions	8			55
Payments	(19		)	(30		)
Revaluation Impact	10			4
Balance at March 31,	$	206		$	133

The fair value of the contingent liability is based on projections of revenue and earnings for the acquired entities that are reassessed on a quarterly basis. As set forth in the table above, based on the Company's ongoing assessment of the fair value of contingent consideration, the Company recorded a net increase in the estimated fair value of such liabilities for prior-period acquisitions of $10 million in the three-month period ended March 31, 2015. A 5% increase in the above mentioned projections would increase the liability by approximately $21 million. A 5% decrease in the above mentioned projections would decrease the liability by approximately $24 million.

Fair Value of Long-Term Investments

The Company holds investments in certain private companies, public companies and certain private equity investments that are accounted for using the equity method of accounting. The carrying value of these investments amounted to $399 million at March 31, 2015 and $388 million at December 31, 2014. The Company's investments in private equity funds were $74 million and $61 million at March 31, 2015 and December 31, 2014, respectively. The carrying values of these private equity investments approximates fair value. The underlying private equity funds follow investment company accounting, where investments within the fund are carried at fair value. The Company records in earnings, investment gains/losses for its proportionate share of the change in fair value of the funds. These investments would be classified as Level 3 in the fair value hierarchy and are included in other assets in the consolidated balance sheets.

During 2014, the Company purchased 34% of the common stock of Alexander Forbes. As of March 31, 2015, the carrying value of the Company’s investment in Alexander Forbes was approximately $278 million. As of March 31, 2015, the market value of the approximately 443 million shares of Alexander Forbes owned by the Company, based on the March 31, 2015 closing share price of 10.54 South African Rand per share, was approximately $386 million. The Company’s investment in Alexander Forbes and its other equity investments in private companies are accounted for using the equity method of accounting and included in revenue in the consolidated income statements and in other assets in the consolidated balance sheets. The Company records its share of income or loss on its equity method investments on a one quarter lag basis.

On February 24, 2015, Mercer purchased shares of common stock of Benefitfocus (NASDAQ:BNFT) constituting approximately 9.9% of BNFT's outstanding capital stock as of the acquisition date. The purchase price for the BNFT shares and certain other rights and other consideration was approximately $75 million. The Company has elected to account for this investment under the cost method of accounting as the shares purchased are categorized as restricted and cannot be sold for more than one year. When the restrictions on sale are less than one year in duration (January 1, 2017), the shares are expected to be classified as available for sale. This investment would then be classified as Level 2 in the fair value hierarchy and included in other assets in the consolidated balance sheets. The value of the BNFT shares based on the closing price on the NASDAQ at March 31, 2015 and without regard to the restrictions on sale was approximately $104 million.

Per Share Data

Basic net income per share attributable to the Company and income from continuing operations per share are calculated by dividing the respective after-tax income 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 by the weighted average number of outstanding shares of the Company’s common stock, which have been adjusted for the dilutive effect of potentially issuable common shares. Reconciliations of the applicable income components used for diluted EPS - Continuing operations and basic weighted average common shares outstanding to diluted weighted average common shares outstanding are presented below. The reconciling items related to the calculation of diluted weighted average common shares outstanding are the same for net income attributable to the Company.

Fiduciary Assets And Liabilities [Abstract]

Fiduciary Assets and Liabilities

Fiduciary Assets and Liabilities

In its capacity as an insurance broker or agent, the Company collects premiums from insureds and, after deducting its commissions, remits the premiums to the respective insurance underwriters. The Company also collects claims or refunds from underwriters on behalf of insureds. Unremitted insurance premiums and claims proceeds are held by the Company in a fiduciary capacity. Risk and Insurance Services revenue includes interest on fiduciary funds of $5 million and $6 million for the three-month periods ended March 31, 2015 and 2014, respectively. The Consulting segment recorded fiduciary interest income of $1 million for each of the three-month periods ended March 31, 2015 and 2014. 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 $8.1 billion at March 31, 2015 and $7.3 billion atDecember 31, 2014. 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 $26 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.

Claims, Lawsuits And Other Contingencies

Mar. 31, 2015

Commitments and Contingencies Disclosure [Abstract]

Claims, Lawsuits, and Other Contingencies

Claims, Lawsuits and Other Contingencies

Litigation Matters

The Company and its subsidiaries are subject to a significant number of claims, lawsuits and proceedings in the ordinary course of business. Such claims and lawsuits consist principally of alleged errors and omissions in connection with the performance of professional services, including the placement of insurance, the provision of actuarial services for corporate and public sector clients, the provision of investment advice and investment management services to pension plans, the provision of advice relating to pension buy-out transactions and the provision of consulting services relating to the drafting and interpretation of trust deeds and other documentation governing pension plans. These claims may seek damages, including punitive and treble damages, in amounts that could, 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 uses 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.

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

Governmental Inquiries and Enforcement Matters

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

Other Contingencies-Guarantees

In connection with its acquisition of U.K.-based Sedgwick Group in 1998, the Company acquired several insurance underwriting businesses that were already in run-off, including River Thames Insurance Company Limited (“River Thames”), which the Company sold in 2001. Sedgwick guaranteed payment of claims on certain policies underwritten through the Institute of London Underwriters (the “ILU”) by River Thames. The policies covered by this guarantee 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 March 31, 2015, 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 July 3, 1980 and October 6, 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 June 30, 2010, the Company 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, the Company establishes liabilities in accordance with FASB ASC Subtopic No. 450-20 (Contingencies - Loss Contingencies). Except as described above, the Company is not able at this time to provide a reasonable estimate of the range of possible loss attributable to these matters or the impact they may have on the Company's consolidated results of operations, financial position or cash flows. This is primarily because these matters are still developing and involve complex issues subject to inherent uncertainty. Adverse determinations in one or more of these matters could have a material impact on the Company's consolidated results of operations, financial condition or cash flows in a future period.

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [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.

The target asset allocation for the Company's U.S. Plan was 62% equities and equity alternatives and 38% fixed income and at March 31, 2015, the actual allocation for the Company's U.S. Plan was 61% equities and equity alternatives and 39% fixed income. The target asset allocation for the Company's U.K. Plans, which comprises approximately 83% of non-U.S. Plan assets, is 48% equities and equity alternatives and 52% fixed income. At March 31, 2015, the actual allocation for the U.K. Plans was 47% equities and equity alternatives and 53% 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 generally uses threshold-based portfolio re-balancing to ensure the actual portfolio remains consistent with target asset allocation ranges.

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

In March 2015, the Company amended its U.S. Post-65 retiree medical reimbursement plan (the "RRA plan"), resulting in its termination, with benefits to certain participants paid through December 31, 2016. As a result of the termination of the RRA plan, the Company recognized a net credit of approximately $125 million in the first quarter of 2015.

After completion of a consultation period with affected colleagues, in January 2014, the Company amended its U.K. defined benefit pension plans to close those plans to future benefit accruals effective August 1, 2014 and replaced those plans, along with its existing U.K. defined contribution plans, with a new, comprehensive defined contribution arrangement. This change resulted in a curtailment of the U.K. defined benefit plans, and as required under GAAP, the Company re-measured the defined benefit plans’ assets and liabilities at the amendment date, based on assumptions and market conditions at that date. As a result of the re-measurement, the projected benefit obligation ("PBO") increased by approximately $147 million and the funded status decreased by approximately $137 million. The change in the PBO and in the funded status relates primarily to a decrease in the discount rate at the re-measurement date. The net periodic benefit costs recognized in 2014 were the weighted average resulting from the December 31, 2013 measurement and the January 2014 re-measurement. The Company recognized a curtailment gain of $65 million in the first quarter of 2014, primarily resulting from the recognition of the remaining unamortized prior service credit related to a plan amendment made in December 2012. This gain was mostly offset by the cost of a transition benefit for certain employees most impacted by the amendment, which is not part of net periodic pension cost.

The weighted average actuarial assumptions utilized to calculate the net periodic benefit costs for the U.S. and significant non-U.S. defined benefit plans are as follows:

Combined U.S. and significant non-U.S. Plans	Pension Benefits				Post-retirement Benefits
March 31,	2015		2014		2015		2014
Weighted average assumptions:
Expected return on plan assets	7.25	%	7.53	%	—	%	—	%
Discount rate	3.79	%	4.74	%	4.08	%	5.03	%
Rate of compensation increase	2.42	%	2.64	%	—	%	—	%

The Company made approximately $42 million of contributions to its U.S. and non-U.S. defined benefit plans in the first three months of 2015. The Company expects to contribute approximately $152 million to its non-qualified U.S. pension and non-U.S. pension plans during the remainder of 2015.

Business Combinations [Abstract]

Acquisitions

Acquisitions

The Company completed 3 acquisitions during the first three months of 2015.

• January – Marsh acquired INGESEG S.A., an insurance brokerage located in Argentina.

• February – Oliver Wyman acquired TeamSAI, a Georgia-based provider of consulting and technical services to the transportation industry, and Mercer acquired Strategic Capital Management AG, a Switzerland-based institutional investment advisor.

Total purchase consideration for acquisitions made during the first three months of 2015 was $32 million, which consisted of cash paid of $20 million and deferred purchase and estimated contingent consideration of $12 million.

Principles of Consolidation and Other Matters (Policies)

3 Months Ended

Mar. 31, 2015

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Accounting

The consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. While certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted pursuant to such rules and regulations for interim filings, the Company believes that the information and disclosures presented are adequate to make such information and disclosures not misleading.

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.

Income Taxes

The Company's effective tax rate in the first quarter of 2015 was 29.2% compared with 29.5% in the first quarter of 2014. These rates reflect non-U.S. income taxed at rates below the U.S. statutory rate, including the effect of repatriation, as well as the impact of discrete tax matters such as changes in circumstances that result in a change in judgment about the beginning balance in valuation allowances, the resolution of tax examinations and expirations of statutes of limitations.

The Company is routinely examined by tax authorities in the jurisdictions in which it has significant operations. The Company regularly considers the likelihood of assessments in each of the taxing jurisdictions resulting from examinations. When evaluating the potential imposition of penalties, the Company considers a number of relevant factors under penalty statutes, including appropriate disclosure of the tax return position, the existence of legal authority supporting the Company's position, and reliance on the opinion of professional tax advisors.

The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in tax returns.

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 Financial Accounting Standards Board ("FASB"). The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy, for disclosure purposes, is determined based on the lowest level input that is significant to the fair value measurement. Assets and liabilities recorded in the consolidated balance sheets at fair value are categorized based on the inputs in the valuation techniques as follows:

Level 1. Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market (examples include active exchange-traded equity securities and money market mutual funds).

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 and 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.

Contingent 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 resulting from the projected revenue and earnings of the acquired entities.

Principles of Consolidation and Other Matters

Principles of Consolidation and Other Matters

The consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. While certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted pursuant to such rules and regulations for interim filings, the Company believes that the information and disclosures presented are adequate to make such information and disclosures not misleading. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 (the "2014 10-K").

The financial information contained herein reflects all adjustments consisting only of normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the Company’s consolidated financial statements as of and for the three-month periods ended March 31, 2015 and 2014.

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 $171 million related to regulatory requirements outside the U.S. or as collateral under captive insurance arrangements.

Investments

The Company holds investments in private companies and private equity funds. Investments in private equity funds are accounted for under the equity method of accounting using a consistently applied three-month lag period adjusted for any known significant changes from the lag period to the reporting date of the Company. The underlying private equity funds follow investment company accounting, where investments within the fund are carried at fair value. The Company records in earnings, investment gains/losses for its proportionate share of the change in fair value of the funds. Investments using the equity method of accounting are included in other assets in the consolidated balance sheets.

The caption “Investment income” in the consolidated statements of income comprises realized and unrealized gains and losses from investments recognized in current earnings. It includes, when applicable, other than temporary declines in the value of debt and available for sale securities and the change in value of the Company’s holdings in certain private equity funds, including equity method gains (losses) on its investment in the Trident funds. The Company’s investments may include direct investments in insurance or consulting companies and investments in private equity funds. The Company recorded investment income of $2 million in the first quarter of 2015 compared to $13 million for the same period in 2014.

Income Taxes

The Company's effective tax rate in the first quarter of 2015 was 29.2% compared with 29.5% in the first quarter of 2014. These rates reflect non-U.S. income taxed at rates below the U.S. statutory rate, including the effect of repatriation, as well as the impact of discrete tax matters such as changes in circumstances that result in a change in judgment about the beginning balance in valuation allowances, the resolution of tax examinations and expirations of statutes of limitations.

The Company is routinely examined by tax authorities in the jurisdictions in which it has significant operations. The Company regularly considers the likelihood of assessments in each of the taxing jurisdictions resulting from examinations. When evaluating the potential imposition of penalties, the Company considers a number of relevant factors under penalty statutes, including appropriate disclosure of the tax return position, the existence of legal authority supporting the Company's position, and reliance on the opinion of professional tax advisors.

The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in tax returns. The Company's gross unrecognized tax benefits increased from

$97 million at December 31, 2014 to $100 million at March 31, 2015. It is reasonably possible that the total amount of unrecognized tax benefits will decrease between zero and approximately $22 million within the next twelve months due to settlements of audits and expirations of statutes of limitation.

On March 27, 2014, the Company and certain of its foreign subsidiaries amended and restated its $1.0 billion facility into a $1.2 billion multi-currency five-year unsecured revolving credit facility. The interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit ratings. This facility expires in March 2019 and requires the Company to maintain certain coverage and leverage ratios which are tested quarterly. There were no borrowings outstanding under this facility at March 31, 2015.

In December 2012, the Company closed on a $50 million, three-year term loan facility. The interest rate on this facility at March 31, 2015 was 1.17%, which 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. The Company had $50 million of borrowings outstanding under this facility at March 31, 2015.

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.

	March 31, 2015				December 31, 2014
(In millions of dollars)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Short-term debt	$	61	$	61	$	11	$	11
Long-term debt	$	3,828	$	4,009	$	3,376	$	3,493

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