On August 3, 2010, MMC completed the sale of Kroll to Altegrity for cash consideration of $1.13 billion. ~~MMC will record the disposal of Kroll in the third quarter of 2010.~~ The account balances and activities of Kroll and KLS were segregated and reported as discontinued operations in the accompanying consolidated balance sheets at ~~June 30, 2010 and~~ December 31, 2009 and the accompanying consolidated statements of income for the three-month and ~~six-month~~nine-month periods ended ~~June~~September 30, 2010 and 2009. The after-tax loss on the disposal of KLS isand the gain-on-sale and tax benefits related to Kroll are included in discontinued operations in 2010.

2.Principles of Consolidation and Other Matters

The consolidated financial statements included herein have been prepared by MMC pursuant to the rules and regulations of the Securities and Exchange Commission. 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, although MMC believes that the information and disclosures presented are adequate to make such information and disclosure not misleading. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in MMC’s Annual Report on Form 10-K for the year ended December 31, 2009 (the “2009 10-K”). and the amended financial information filed in MMC’s Current Report on Form 8-K dated September 2, 2010.

~~- 9 -~~

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 MMC’s results of operations for the ~~six-month~~three and nine month periods ended ~~June~~September 30, 2010 and 2009.

MMC reported ~~a net income~~an effective tax ~~benefit~~rate of ~~$60 million~~30.0% in continuing operations in the ~~second~~third quarter of ~~2010 on a pretax loss of $89 million, an~~2010. The 20.8% effective tax rate for the first nine months of ~~67.4%. The high tax benefit rate~~2010 primarily reflects the ~~combination of the tax~~ benefit ~~related to~~associated with the Alaska settlement ~~determined at~~recorded in the second quarter. This results from the deduction of the settlement from U.S. income, which has a relatively higher effective tax ~~rates,~~rate, combined with other ~~pretax~~pre-tax income that is subject to lower average effective tax rates applicable worldwide. Excluding the impact of the Alaska settlement, the effective tax rate for the quarter was 32.3%. The 14.9% effective tax rate for the first six months of 2010 also primarily reflects the benefit associated with the Alaska settlement. Excluding the effect of the settlement, the effective tax rate for the first ~~six~~nine months was ~~29.5%~~29.6%. ~~The increase in effective~~

In the third quarter of 2009 MMC reported a tax ~~rates compared to 2009, excluding the Alaska settlement, primarily reflects~~benefit of $46 million on pretax income of $161 million. This includes a ~~change~~net benefit of $95 million resulting from a decrease in the ~~worldwide mix~~liability for unrecognized tax benefits and accrued interest related to prior tax years as a result of ~~earnings.~~

~~MMC’s 21.9%~~expiring statutes of limitations, audit settlements, and changes in estimates. Excluding this benefit, the effective tax rate infor the ~~second~~third quarter of 2009 ~~primarily reflects a favorable adjustment from reducing the forecasted, full-year effective tax rate compared with the estimate as of the first quarter.~~was 30.4%. The effective tax rate for the first ~~six~~nine months of 2009 was ~~27.4%~~12.7%. Excluding the effect of the benefit from the decrease in the liability for unrecognized tax benefits recognized in the third quarter, the effective tax rate for the first nine months of 2009 was 28.1%.

The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in the tax return. It is reasonably possible that the total amount of unrecognized tax benefits will decrease between zero and approximately $80 million within the next twelve months due to settlement of audits and expiration of statutes of limitation.

The caption “Investment income (loss)” in the consolidated statements of income comprises realized and unrealized gains and losses from investments recognized in current earnings. It includes, when applicable, other than temporary declines in the value of available for sale securities and the change in value of MMC’s holdings in certain private equity funds. MMC’s investments may include direct investments in insurance or consulting companies and investments in private equity funds. Equity method gains (losses) of $18 million and $(33) million are included in this line for the three month periods ended June 30, in 2010 and 2009, respectively. Equity method gains (losses) of $17 million and $(51) million are included in this line for the six month periods ended June 30, 2010 and 2009.

MMC has an investment in Trident II limited partnership, a private equity investment fund. MMC recorded losses of $4 million and gains of $22 million for the three month periods ended September 30, 2010 and 2009, respectively and gains of $13 million and losses of $29 million for the nine month periods ended September 30, 2010 and 2009, respectively related to

Trident II. At ~~June~~September 30, 2010, MMC’s investment in Trident II was approximately ~~$151~~$146 million, reflected in the other assets in consolidated balance sheet. MMC’s maximum exposure to loss is equal to its investment plus any calls on its remaining capital commitment of ~~$81~~$67 million. Since this fund is closed to new investments, none of the remaining capital commitment is expected to be called.

3.Fiduciary Assets and Liabilities

In its capacity as an insurance broker or agent, MMC collects premiums from insureds and, after deducting its commissions, remits the premiums to the respective insurance underwriters. MMC also collects claims or refunds from underwriters on behalf of insureds. Unremitted insurance premiums and claims proceeds are held by MMC in a fiduciary capacity. Risk and Insurance Services revenue includes interest on fiduciary funds of ~~$22~~$33 million and ~~$28~~$42 million for the ~~six-month~~nine month periods ended ~~June~~September 30, 2010 and 2009, respectively. The Consulting segment recorded fiduciary interest income of $2$3 million ~~for~~in each of the ~~comparable~~nine month periods inended September 30, 2010 and 2009. Since fiduciary assets are not available for corporate use, they are shown in the consolidated balance sheets as an offset to fiduciary liabilities.

Fiduciary assets include approximately ~~$371~~$318 million and $577 million of fixed income securities classified as available for sale at ~~June~~September 30, 2010 and December 31, 2009, respectively. Unrealized gains or losses from available for sale securities are recorded in other comprehensive income until the securities are disposed of, or mature. Unrealized gains, net of tax, at ~~June~~September 30, 2010 were ~~$8 million and $12 million at June 30, 2010 and December 31, 2009, respectively.~~$7 million.

Net uncollected premiums and claims and the related payables amounted to ~~$10.3~~$9.5 billion at ~~June~~September 30, 2010 and $9.9 billion at December 31, 2009. MMC 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 MMC and are not included in the accompanying consolidated balance sheets. ~~Mercer had approximately $.4 billion of fiduciary assets at June 30, 2010 and December 31, 2009.~~

~~- 10 -~~

In certain instances, MMC 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.

4.Per Share Data

Effective January 1, 2009, MMC adopted the guidance for the calculation of earnings per share (“EPS”) for share-based payment awards with rights to dividends or dividend equivalents. The guidance indicates that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and should be included in the computation of basic and dilutive EPS using the two-class method.

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

Diluted net income per share attributable to MMC and income from continuing operations per share are calculated by dividing the respective after-tax income attributable to common shares

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

7.Acquisitions

~~In 2010,~~ MMC ~~has~~ made four acquisitions in its Risk and Insurance Services segment during the first half of 2010 and two acquisitions in its Consulting segment in the third quarter of ~~which were made~~2010.

In July 2010, Mercer acquired IPA, a provider of health and benefit recordkeeping and employee enrollment technology. In August 2010, Mercer acquired ORC Worldwide, a premier provider of HR knowledge, data and solutions for professionals in numerous industries.

In the second quarter of ~~2010.~~

~~On April 1,~~ 2010, Marsh completed the acquisition of HSBC Insurance Brokers Ltd. This transaction deepens Marsh’s presence in the U.K., Hong Kong, Singapore, China and the Middle East. As part of the acquisition agreement, Marsh also entered into a strategic partnership with HSBC Bank that gives MMC preferred access to provide insurance broking and risk management services to HSBC and their corporate and private clients. ~~On April 30, 2010,~~Also in the second quarter, Marsh & McLennan Agency acquired the Bostonian Group, one of the largest regional

~~- 13 -~~

insurance brokerages in New England. ~~This transaction increases Marsh’s middle market presence. During~~In the first quarter of 2010, Marsh acquired Haake Companies, Inc., one of the largest independent insurance broking firms in the Midwest, and Thomas Rutherfoord, Inc., one of the largest insurance broking firms in the Southeast and mid-Atlantic regions in the U.S. These acquisitions were made to expand Marsh’s share in the middle-market through Marsh & McLennan Agency.

Total purchase consideration for the ~~four~~six acquisitions made during 2010 was ~~$472~~$530 million which consisted of cash paid of ~~$239~~$282 million, the issuance of ~~7.4~~7.6 million shares with a fair value of ~~$178~~$183 million, and estimated contingent consideration of ~~$55~~$65 million. Contingent consideration arrangements are primarily based on EBITDA and revenue targets over two to four years. The fair value of the contingent consideration was based on earnings projections of the acquired entities. Estimated fair values of assets acquired and liabilities assumed are subject to adjustment when purchase accounting is finalized.

In 2010, MMC also paid ~~$14~~$21 million of deferred purchase consideration, $3 million for the purchase of other intangible assets and $2 million of contingent purchase consideration related to acquisitions made in prior years.

Therefore, MMC recorded a decrease to additional paid in capital in the first quarter of 2009 of $38 million related to this transaction.

8.Dispositions

On August 3, 2010, MMC completed ~~its~~the sale of Kroll to Altegrity for cash proceeds of $1.13 billion. Kroll’s assets and liabilities are reported in discontinued operations at December 31, 2009. The ~~account balances~~pre-tax gain of $25 million, the tax benefit related to the disposal, Kroll’s results through August 3, 2010, and ~~activities of Kroll were segregated and reported as~~comparative results are included in discontinued operations in the accompanying consolidated ~~balance sheets at June 30, 2010 and December 31, 2009 and the accompanying consolidated~~ statements of ~~income for the three-month and six-month periods ended June 30, 2010 and 2009. MMC will record the disposal of Kroll in the third quarter of 2010.~~income.

MMC’s tax basis in its investment in the stock of Kroll ~~exceeds~~exceeded the recorded amount primarily as a result of prior impairments of goodwill recognized for financial reporting, but not for tax. Prior to the second quarter of 2010, a tax benefit ~~was~~had not been recorded for this temporary difference because it was not apparent in the foreseeable future that it would reverse in a transaction that would result in a tax benefit. Since Kroll met the criteria for classification as a discontinued operation in the second quarter of 2010, MMC determined that it had the ability to carry back the capital loss realized against prior realized capital gains. Therefore, a $265 million deferred tax benefit was recorded in discontinued operations in the second quarter of 2010 to establish a deferred tax asset.

~~- 15 -~~

In the first quarter of 2010, Kroll completed the sale of KLS. The after-tax loss on this disposal is included in discontinued operations in 2010. The operating results of KLS ~~have been reclassified into~~are included in discontinued operations.

In the second quarter of 2009, Kroll completed the sale of Kroll Government Services (“KGS”). The operating results of KGS ~~for the second quarter of 2009~~ are included in discontinued operations. Discontinued operations in ~~the second quarter of~~ 2010 and 2009 also includes the accretion of interest related to an indemnity for uncertain tax positions provided as part of the purchase by Great West Lifeco Inc. of Putnam Investments Trust from MMC in August 2007.

^(c)

The ~~six~~income tax credit related to the disposal of discontinued operations for the nine months ended September 30, 2010 primarily represents the recognition of tax benefits recorded in the second quarter when MMC concluded the sale of Kroll was probable. The nine months of 2010 also includes a tax provision of $36 million on the sale of KLS.

The assets and liabilities of Kroll are classified as current assets, non-current assets and current liabilities of discontinued operations in the Consolidated Balance Sheets at ~~June 30, 2010 and~~ December 31, 2009. The assets of Kroll primarily consist of goodwill, other identified intangible assets, commissions and fees receivable and fixed assets.

9.Goodwill and Other Intangibles

MMC is required to assess goodwill and any indefinite-lived intangible assets for impairment annually, or more frequently if circumstances indicate impairment may have occurred. MMC performs the annual impairment test for each of its reporting units during the third quarter of each year. Fair values of the reporting units are estimated using a market approach or a discounted cash flow model. Carrying values for the reporting units are based on balances at the prior quarter end and include directly identified assets and liabilities as well as an allocation of those assets and liabilities not recorded at the reporting unit level. MMC completed its 2010 annual review in the third quarter and concluded goodwill was not impaired.

MMC completed the sale of Kroll on August 3, 2010. Goodwill related to Kroll has been reflected as assets of discontinued operations at December 31, 2009.

As previously reported, in the second quarter of 2009, Kroll completed the sale of KGS, its U.S. government security clearance screening business. As a result of the sale, MMC allocated goodwill between KGS (the portion of the reporting unit sold) and Kroll (the portion of the

~~- 16 -~~

reporting unit retained), based on the relative fair value of the two portions. In addition, MMC evaluated the portion of the reporting unit retained for potential impairment. Fair value was estimated using a market approach, based on management’s latest projections and outlook for the businesses in the current environment. This fair value determination was categorized as level 3 in the fair value hierarchy. On the basis of the step one impairment test, MMC concluded that goodwill in the reporting unit was impaired and completed the required step two portion of the impairment assessment. A step two impairment test, which under ASC Topic No. 350 (“Intangibles – Goodwill and Other”) is required to be completed after an impairment is indicated in a step one test, requires a complete re-valuation of all assets and liabilities of the reporting units in the same manner as a business combination. MMC recorded a non-cash charge of $315 million to write down Kroll’s goodwill to its estimated fair ~~value.~~value in 2009. This charge is included in discontinued operations, which also includes the operating results of Kroll.

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:

10.Fair Value Measurements

Fair Value Hierarchy

MMC has categorized its assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy as defined by the FASB in ASC Topic No. 820 (“Fair Value Measurements and Disclosures”). The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Assets and liabilities recorded in the consolidated balance sheets at fair value are categorized based on the inputs in the valuation techniques as follows:

~~Level 1.~~ Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market (examples include active exchange-traded equity securities, most U.S. Government and agency securities, money market mutual funds and certain other sovereign government obligations).

Level 1.

Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market (examples include active exchange-traded equity securities, most U.S. Government and agency securities, money market mutual funds and certain other sovereign government obligations).

~~Level 2.~~ ~~Assets and liabilities whose values are based on the following:~~

Level 2.

Assets and liabilities whose values are based on the following:

Quoted prices for similar assets or liabilities in active markets;

Quoted prices for identical or similar assets or liabilities in non-active markets (examples include corporate and municipal bonds, which trade infrequently);

Pricing models whose inputs are observable for substantially the full term of the asset or liability (examples include most over-the-counter derivatives, including interest rate and currency swaps); and

Pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full asset or liability (for example, certain mortgage loans).

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.~~

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.

~~- 18 -~~

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).

Valuation Techniques

Equity Securities & Mutual Funds

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

Other Sovereign Government Obligations, Municipal Bonds and Corporate Bonds

The investments listed in the caption above are valued on the basis of valuations furnished by an independent pricing service approved by the trustees or dealers selected by Putnam Investment Management LLC (“Putnam Management”), manager of the Putnam mutual funds, a wholly owned subsidiary of Putnam LLC. Such services or dealers determine valuations for normal institutional-size trading units of such securities using methods based on market transactions for comparable securities and various relationships, generally recognized by institutional traders, between securities.

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 ~~June~~September 30, 2010 and December 31, 2009.

11.Retirement Benefits

MMC maintains qualified and non-qualified defined benefit pension plans for its U.S. and non-U.S. eligible employees. MMC’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 MMC offers defined benefit plans.

The target asset allocation for the U.S. Plan was changed recently from 65% equities and 35% fixed income to 55% equities and 45% fixed income. ~~Implementation of the new target asset allocation is underway.~~ At the end of the ~~second~~third quarter of 2010, the actual allocation for the U.S. Plan was ~~64%~~60% equities and ~~36%~~40% fixed income. The target asset allocation for the U.K. Plan, which comprises approximately 83% of non-U.S. Plan assets, is 58% equities and 42% fixed income. At the end of the ~~second~~third quarter of 2010, the actual allocation for the U.K. Plan was ~~55%~~56% equities and ~~45%~~44% fixed income.

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

16.Claims, Lawsuits and Other Contingencies

~~Governmental Inquiries and Claims~~

In December 2007, the Alaska Retirement Management Board filed a civil lawsuit against Mercer (US) Inc. in Alaska state court. Plaintiff, represented by the Alaska Law Department (through the Alaska Attorney General) and the law firm of Paul, Weiss, Rifkind, Wharton & Garrison LLP, filed an amended complaint in May 2009. The amended complaint alleged professional negligence and malpractice, breach of contract, breach of the implied covenant of good faith and fair dealing, negligent misrepresentation, unfair trade practices and fraud and misrepresentation related to actuarial services that Mercer provided to the Alaska Division of Retirement and Benefits relating to two State pension and benefit plans, the Alaska Public Employees Retirement System and the Alaska Teachers Retirement System. The amended complaint sought damages of “at least $2.8 billion” plus treble damages related to the unfair trade practices claim, punitive damages, attorneys’ fees, costs and interest. The parties resolved this matter in June 2010. Mercer has agreed to pay $500 million, of which $100 million will be covered by insurance. The cost of this settlement and the related insurance receivable have been reflected in MMC’s consolidated financial statements for the quarter ended June 30, 2010.

In October 2007, the State of Connecticut brought a civil action against Guy Carpenter in Connecticut state court alleging that Guy Carpenter violated the state’s antitrust and unfair trade practices laws by engaging in allocation of markets, price-fixing and other allegedly improper conduct by taking part in the operation of several reinsurance facilities over a period of decades. An amended complaint was filed in October 2009. The amended complaint alleges damages to Guy Carpenter’s insurance company clients and their customers, as well as to the general economy of Connecticut, and seeks monetary damages, civil penalties, attorneys’ fees, costs and injunctive and other equitable relief. Discovery is underway in this matter.

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

Errors and Omissions Claims

MMC and its subsidiaries, particularly Marsh and Mercer, are subject to a significant number of ~~other~~ 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 and the provision of actuarial services. Certain of these claims 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—~~(Contingencies – Loss Contingencies), MMC utilizes internal actuarial and other estimates, and case level reviews by inside and outside counsel. 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, MMC has not recorded a liability, other than for legal fees to defend the claim, because MMC is 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 MMC’s deductible in any policy year, MMC also records an asset for the amount that MMC expects to recover under any available third-party insurance programs. MMC has varying levels of third-party insurance coverage, with policy limits and coverage terms varying significantly by policy year. MMC is not aware of coverage defenses or other obstacles to coverage that would limit recoveries through policy year 2001-2002 in a material amount. ~~From~~Beginning in 2002, ~~to 2008,~~ the availability of third-party insurance declined significantly.

~~Brokerage Compensation Practices Settlement~~Governmental Inquiries and Related ~~Actions~~Claims

In January 2005, MMC and its subsidiary Marsh Inc. entered into a settlement agreement with the New York State Attorney General (“NYAG”) and the New York State Insurance Department to settle a civil complaint and related citation alleging that Marsh’s use of market service agreements with various insurance companies entailed fraudulent business practices, bid-rigging, illegal restraint of trade and other statutory violations. The parties subsequently entered into an amended and restated settlement agreement in February ~~2010.

Numerous private party lawsuits based on similar allegations to those made in the NYAG complaint were commenced against MMC, one or more of its subsidiaries, and their current and former directors and officers. The status of the lawsuits that remain outstanding is as follows:

A settlement of the claims against MMC, Marsh and certain Marsh subsidiaries in two consolidated putative class actions that were pending in the U.S. District Court for the District of New Jersey (one on behalf of a purported class of “commercial” policyholders and the second on behalf of a purported class of “employee benefit” policyholders) was approved in February 2009 and is now final. Nine actions instituted by individual policyholders against MMC, Marsh and certain Marsh subsidiaries are pending in federal and state courts.

MMC, Marsh and certain Marsh subsidiaries were named as additional defendants in a shareholder derivative suit pending in the Delaware Court of Chancery against the directors and officers of American International Group, Inc. (“AIG”) and others. The suit alleged that MMC, Marsh and the Marsh subsidiaries engaged in conspiracy and fraud with respect to the alleged misconduct described in the NYAG complaint, and that they aided and abetted current and former directors and officers of AIG in breaching their fiduciary duties to AIG with respect to AIG’s participation in the alleged misconduct. In June 2009, the Delaware court granted a motion to dismiss all claims against MMC and the Marsh defendants. An appeal of this dismissal is currently pending in the Delaware Supreme Court.

On June 11, 2010, MMC announced that it had resolved litigation brought by the Alaska Retirement Management Board (“ARMB”) on behalf of ~~a purported class of “commercial” policyholders~~two Alaska benefit plans against Mercer, relating to work in the period 1992 to 2004.

Other ~~Contingencies—~~Contingencies – Guarantees

In connection with its acquisition of U.K.-based Sedgwick Group in 1998, MMC acquired several insurance underwriting businesses that were already in run-off, including River Thames Insurance Company Limited (“River Thames”), which MMC 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 June 30, 2010, 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 MMC under the guarantee.

From 1980 to 1983, MMC owned indirectly the English & American Insurance Company (“E&A”), which was a member of the ILU. The ILU required MMC 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 MMC’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 MMC anticipates that additional claimants may seek to recover against the letter of credit.

Putnam-related Matters

Under the terms of a stock purchase agreement with Great-West Lifeco Inc. (“GWL”) related to GWL’s purchase of Putnam Investments Trust from MMC in August 2007, a copy of which was included as an exhibit to MMC’s Current Report on Form 8-K filed on February 1, 2007, MMC agreed to indemnify GWL with respect to certain Putnam-related litigation and regulatory matters. Two putative class actions by investors in certain Putnam Funds pending against Putnam in the District of Maryland are based on similar allegations as those at issue in Putnam’s 2003 and 2004 settlements with the SEC and the Commonwealth of Massachusetts

~~- 27 -~~

regarding excessive short-term trading by certain former Putnam employees in shares of the Putnam mutual funds (the “Putnam Funds”), and directly involve MMC and/or may be subject to MMC’s indemnification obligations. The first action asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Section 36(b) of the Investment Company Act of 1940. The second action purports to assert derivative claims under Section 36(b) of the Investment Company Act. Both suits seek to recover unspecified damages allegedly suffered by the Putnam Funds and their investors as a result of purported market-timing and late trading activity in certain Putnam Funds. In the first action, the parties have entered into a settlement ~~agreement. That~~ agreement, ~~is subject to final approval~~which was recently approved by the district court. In the derivative action, the court denied Putnam’s motion for summary judgment.

Kroll-related Matters

Under the terms of a stock purchase agreement with Altegrity, Inc. (“Altegrity”) related to Altegrity’s purchase of Kroll from MMC in August 2010, a copy of which is attached as an exhibit ~~2.1~~ to ~~this~~MMC’s Quarterly Report on Form 10-Q for the period ended June 30, 2010, MMC 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 16 on Claims, Lawsuits and Other Contingencies may expose MMC or its subsidiaries to liability for significant monetary damages and other forms of relief. Where a loss is both probable and reasonably estimable, MMC establishes liabilities in accordance with FASB ASC Subtopic No. 450-20 ~~(Contingencies—~~(Contingencies – Loss Contingencies). Except as described above, MMC 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 MMC’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 MMC’s consolidated results of operations, financial condition or cash flows in a future period.

18.New Accounting Pronouncements

Effective January 1, 2009, MMC adopted the guidance for calculating EPS using the two-class method with retroactive application to prior periods. The impact of adopting the guidance is discussed in Note 4 to the consolidated financial statements.

Effective January 1, 2009, the Company adopted the new guidance issued by the FASB for Business Combinations. The guidance requires entities in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction; establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed; and requires the acquirer to disclose all information needed by investors and other users to evaluate and understand the nature and financial effect of the business combination.

Effective January 1, 2009, the Company adopted the new guidance issued by the FASB for Consolidation – Non-controlling Interests, which did not have a material impact on our financial condition, results of operations or cash flows. However, it did impact the presentation and disclosure of non-controlling (minority) interests in our consolidated financial statements. The effects of this change are reflected herein.

The new guidance also requires adjustment of net income to include the net income attributable to the non-controlling interests and a new separate caption for net income attributable to MMC to be presented in the consolidated statement of earnings.

~~- 30 -~~

In February 2008, the FASB issued guidance related to Fair Value Measurements which delayed until the second quarter of 2009, fair value measurement for non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company has applied the provision of this new guidance to its financial statement disclosures beginning in the second quarter of 2009.

On April 1, 2009, the FASB issued guidance for “Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies”, to address application issues raised by preparers, auditors and attorneys. The guidance requires recognition of contingent assets or liabilities (arising from a business combination contingency) at fair value, at the acquisition date if the acquisition-date fair value of the asset or liability can be determined during the measurement period, or if certain criteria are met. Otherwise, the acquirer should not recognize an asset or liability as of the acquisition date. The guidance is effective for business combinations occurring on or after January 1, 2009. This new guidance did not have a material impact on MMC’s financial condition or reported results.

In the second quarter of 2009, MMC adopted the guidance issued by the FASB for interim disclosures about fair value of financial instruments. The guidance, which is effective for interim periods ending after ~~June~~September 15, 2009, requires disclosures about the fair values of financial instruments in interim period reports of publicly traded companies as well as in annual financial statements. The adoption of this guidance did not have a material impact on MMC’s financial condition or reported results.

In the second quarter of 2009, MMC adopted the guidance issued by the FASB for Recognition and Presentation of Other-Than-Temporary Impairments. It amends GAAP guidance including SEC SAB Topic 5M and other authoritative literature that allow the holders of debt securities not to recognize other-than-temporary impairments based on their intent and ability to hold a security until recovery in fair value to its amortized cost. The other-than-temporary impairment model applies only to debt securities and not equity securities. The guidance requires recognition of a credit loss (the difference between the present value of cash flows expected to be collected and the amortized cost basis) through earnings. The guidance is effective for interim and annual periods ending after ~~June~~September 15, 2009. The adoption of this guidance did not have a material impact on MMC’s financial condition or reported results.

In December 2008, the FASB issued guidance for Employers’ Disclosures About Pension and Other Post Retirement Benefit Plan Assets. The guidance requires fair value plan asset disclosures for an employer’s assets in defined benefit pension and postretirement plans similar to the guidance on Fair Value Measurements, as well as (a) how investment allocation decisions are made, (b) the major categories of plan assets, and (c) significant concentrations of risk within plan assets. The guidance is effective for fiscal years ending after December 15, 2009. The Company has applied the provision of this new guidance to its financial statement disclosures beginning December 31, 2009.

In December 2009, the FASB issued new guidance related to the Consolidation of Variable Interest Entities (“VIE”) and transfer of assets. The new guidance focuses on ‘controlling financial interests’ and requires companies to perform qualitative analysis to determine whether they must consolidate a VIE by assessing whether the variable interests give them controlling financial interests in the VIE. This guidance is effective for transfers occurring on or after November 15, 2009. Provisions must be applied in annual reporting periods beginning after November 15, 2009 and interim periods within that annual period. The adoption of the guidance did not have a material impact on the Company’s financial statements. Also, effective January 1, 2010, the Company adopted new guidance that indefinitely defers the above changes relating to the Company’s interests in entities that have all the attributes of an

~~- 31 -~~

investment company or for which it is industry practice to apply measurement principles for financial reporting that are consistent with those applied by an investment company. As a result, the above guidance did not apply to certain investment management trusts managed by Mercer.

In January 2010, the FASB issued new guidance that adds additional disclosures about transfers into and out of Levels 1 and 2 items and separate disclosures about purchases, sales, issuances, and settlements related to Level 3 measurements. It also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. Further, the new guidance amends the requirements on employer’s disclosures about postretirement benefit plan assets to require disclosures be provided by classes of assets instead of by major categories of assets. This guidance is effective for the first reporting period beginning after December 31, 2009, except for the requirement to provide the Level 3 activity of purchases, sales, issuances, and settlements on a gross basis, which will be effective for fiscal years beginning after December 15, 2010. The adoption of the guidance did not have a material impact on the Company’s financial statements.

In October 2009, the FASB amended its guidance on revenue recognition regarding multiple-deliverable revenue arrangements. The guidance is effective prospectively for arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The Company is evaluating the impact of adopting this new guidance.

On April 29, 2010, the FASB issued guidance which establishes a revenue recognition model for contingent consideration that is payable upon the achievement of an uncertain future event, referred to as a milestone. The scope of this guidance is limited to research or development arrangements and requires an entity to record the milestone payment in its entirety in the period received if the milestone meets all the necessary criteria to be considered substantive. However, entities would not be precluded from making an accounting policy election to apply another appropriate accounting policy that results in the deferral of some portion of the arrangement consideration. This is effective for fiscal years (and interim periods within those fiscal years) beginning on or after June 15, 2010. Early application is permitted. Entities can apply this guidance prospectively to milestones achieved after adoption. However, retrospective application to all prior periods is also permitted. The Company is evaluating the impact of adopting this new guidance.

In May 2010, the FASB issued guidance for foreign currency issues and Venezuela’s highly inflationary status. The guidance states that Venezuela’s economy should be considered highly inflationary as of January 1, 2010 and therefore a U.S. dollar reporting entity must remeasure the financial statements of its Venezuelan subsidiaries as if the subsidiaries’ functional reporting currency were the entity’s reporting currency (i.e., the U.S. dollar). Any differences between the U.S. dollar denominated balances recorded by the Venezuelan subsidiaries and the amounts reported in the entity’s consolidated financial statements must be recognized in earnings or as part of its cumulative translation adjustment. The adoption of the guidance did not have a material impact on the Company’s financial statements.

~~- 32 -~~On July 21, 2010, the FASB issued guidance requiring more robust and disaggregated disclosures about the credit quality of an entity’s financing receivables and its allowance for credit losses. The objective of enhancing these disclosures is to improve financial statement users’ understanding of (1) the nature of an entity’s credit risk associated with its financing receivables and (2) the entity’s assessment of that risk in estimating its allowance for credit losses as well as changes in the allowance and the reasons for those changes. The new and amended disclosures that relate to information as of the end of a reporting period will be effective for the first interim or annual reporting periods ending on or after December 15, 2010. However, the disclosures that include information for activity that occurs during a reporting period will be effective for the first interim or annual periods beginning after December 15, 2010. The Company is evaluating the impact of adopting this new guidance.

MMC reported a consolidated operating ~~loss~~income of ~~$(50)~~$239 million in the ~~second~~third quarter of 2010 compared with operating income of ~~$294~~$195 million in the prior year. This reflects the impact of revenue growth in the Risk & Insurance Services segment of 8% and Consulting segment of 5%, compared to an increase in expense of 8% in the Risk & Insurance Services segment and a 3% increase in the Consulting segment.

MMC reported consolidated operating income of $614 million for the first nine months of 2010 compared with $806 million in the prior year. On June 11, 2010, MMC announced that it had resolved litigation brought by the Alaska Retirement Management Board (“ARMB”) on behalf of two Alaska benefit plans against Mercer, relating to work in the period 1992 to 2004. This settlement, in which Mercer expressly denies liability, resolves all claims against Mercer by the ARMB and the State of Alaska related to this matter. Under the terms of the settlement agreement, Mercer ~~has agreed to pay~~paid $500 million, of which $100 million ~~will be~~is covered by insurance. ~~The second quarter~~Year to date results include a net charge of $400 million in the Consulting segment, which after the effect of income taxes, reduced earnings by approximately $0.44 per share. In 2009, Mercer recorded ~~incremental professional liability~~ costs of approximately $30 million relating to a professional liability settlement.

~~MMC reported consolidated operating income of $375 million for the first six months of 2010 compared with $611 million in the prior year.~~

Excluding the charges in Mercer discussed above, operating income would have been ~~$775 million~~$1.0 billion or ~~21%~~26% above last year. This reflects a ~~$63~~$78 million increase in the Risk and Insurance Services segment, a ~~$42~~$75 million increase in Consulting and a reduction in Corporate and other expenses of ~~$29 million,~~$25 million. The decrease in corporate and other is primarily related to lower restructuring and related costs in 2010 versus ~~2009.~~2009, and the impact of $8 million of payments received in 2010 related to the Corporate Advisory and Restructuring businesses disposal in 2008.

~~- 34 -~~

The devaluation of Venezuela’s bolivar currency in January of 2010 did not have a material impact on MMC’s results of operations or financial position.

Consolidated Revenue and Expense

MMC conducts business in many countries, as a result of which the impact of foreign exchange rate movements may distort period-to-period comparisons of revenue. Similarly, 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 and acquisitions and dispositions, including transfers among businesses, on MMC’s operating revenues by segment is as follows:

Restructuring

Actions Initiated in 2010

For the first ~~six~~nine months of 2010, MMC implemented restructuring actions which resulted in costs totaling ~~$41~~$61 million, primarily related to severance and benefits. Approximately ~~$25~~$34 million of these costs related to cost reduction activities for ~~recent acquisitions.~~acquisitions made during 2010. Total costs were incurred as follows: Marsh ~~- $22~~– $35 million, Guy Carpenter ~~- $15~~– $16 million, Mercer ~~- $2~~– $8 million and MMC -– $2 million. These activities resulted in the elimination of approximately ~~150~~260 positions at Marsh, 7080 positions at Guy Carpenter, 40120 positions at Mercer and 50 positions at MMC.

The annualized cost savings from these actions are expected to be approximately ~~$35~~$55 million.

Revenue

Revenue in the Risk and Insurance Services segment in the ~~second~~third quarter of 2010 increased 9%8%, or 1%2% on an underlying basis compared with the same period in 2009. This performance was achieved in an economic environment of continued soft market conditions for commercial property-casualty insurance and a decline in the volume of net written premiums in the property-casualty industry, which has been adversely affected by recessionary conditions over the past two years.

In Marsh, revenue in the ~~second~~third quarter of 2010 was ~~$1.2~~$1.1 billion, an increase of 9% from the same quarter of the prior year reflecting a 3% growth in underlying revenue, a 7% increase from acquisitions, ~~and~~partly offset by a 1% ~~increase~~decrease resulting from the impact of foreign currency translation. ~~Revenue increased 1% on an~~The underlying ~~basis, reflecting~~revenue increase of 3% was achieved despite the economic environment and the ~~downward pressure on commercial~~soft pricing environment in the global property-casualty insurance ~~premium rates.~~

~~Despite these difficult market conditions,~~market. Marsh increased revenues in ~~several~~all its geographies, showing strong new business growth for the quarter. Underlying revenue ~~increases of 3% in EMEA, 13%~~increased 4% in Latin America, ~~and 12%~~3% in Asia Pacific, ~~were mostly offset by a 4% decrease~~3% in U.S. / ~~Canada.~~Canada and 1% in EMEA.

In the first quarter of 2010, Marsh acquired Haake Companies, Inc., one of the largest insurance agencies in the Midwest, and Thomas Rutherfoord, Inc., one of the largest insurance broking firms in the Southeast and mid-Atlantic regions of the U.S. ~~On April 1,~~In the second quarter of 2010, Marsh completed the acquisition of HSBC Insurance Brokers Ltd., an international provider of risk intermediary and risk advisory ~~services. On April 30, 2010, Marsh acquired~~services and the Bostonian Group, one of the largest regional insurance brokerages in New England.

Guy Carpenter’s revenue increased 7%4% to ~~$243~~$233 million in the ~~second~~third quarter of 2010 compared with the same period in 2009, or 2%3% on an underlying basis. The increase in underlying revenue was ~~primarily~~ due to continued strong revenue retention and new business. Guy Carpenter continues to maintain revenue growth during a difficult economic and pricing environment. In April 2009, Guy Carpenter acquired John B. Collins Associates, Inc., previously the fifth-largest reinsurance intermediary in the U.S. and seventh-largest in the world. In October 2009, Guy Carpenter completed the acquisition of London-based specialty reinsurance broker Rattner Mackenzie Limited from HCC Insurance Holdings, Inc.

Fiduciary interest income was $11 million in the ~~second~~third quarter of 2010, a decrease of ~~22%~~11% compared with the same period of 2009, driven by lower interest rates, partly offset by the impact of foreign exchange rates.

Revenue in the Risk and Insurance Services segment increased 9% for the first ~~six~~nine months of 2010 compared with the same period of 2009 ~~and was flat~~or 1% on an underlying basis.

~~Goodwill Impairment Tests~~

In its 2009 10-K, MMC disclosed that the fair value of its Oliver Wyman (“OW”) reporting unit, as measured in the third quarter 2009 goodwill impairment test (the “2009 test”) had declined substantially compared with the prior year. MMC did not conclude the reporting unit was at substantial risk of failing, but disclosure of the decline in fair value was made to highlight the increased risk of possible goodwill impairment compared with prior tests. In the 2009 test, the fair value of OW exceeded its carrying value by 20%. Goodwill allocable to the OW reporting unit was approximately $500 million at June 30, 2010.

~~MMC principally used a market approach to estimate the fair value of OW in the 2009 test.~~

~~- 40 -~~

~~Under this method, projected revenue, net operating income~~severance, restructuring and EBITDA for 2009 (actual results through June 30, 2009 and projected results thereafter), as well as market multiples of comparable companies are key elements that go into the fair value determination. OW’s aggregate performance for the last four quarters (third and fourth quarters of 2009 and first and second quarters of 2010), has exceeded the projected amounts used in the 2009 test. However, the fair value estimate that will be prepared and used for the third quarter 2010, goodwill impairment test will be dependent on assumptions about OW’s future revenue and performance, market multiples of comparable companies and OW’s performance in relation to those comparable companies. Movements in any or all or those variables could result in a fair value estimate for OW that is lower than its carrying value.recoverable expenses from clients.

Corporate Expenses and Other

Corporate expenses in the ~~second~~third quarter of 2010 were ~~$33~~$41 million compared with ~~$47~~$37 million in the prior year. The ~~decrease~~increase is primarily due to ~~lower restructuring and~~higher consulting costs related ~~charges in 2010~~to corporate initiatives compared with 2009. Corporate expenses for the ~~six-months~~nine months of 2010 decreased ~~$29~~$25 million from 2009 due to lower restructuring charges and consulting ~~fees.~~fees and the impact of $8 million of payments received in 2010 related to the Corporate Advisory and Restructuring businesses disposal in 2008.

Interest

Interest income earned on corporate funds amounted to $3$6 million in the ~~second~~third quarter of 2010, compared with $4$3 million in the ~~second~~third quarter of 2009. The ~~decrease in interest income~~increase is primarily due to ~~lower average~~higher non-U.S. interest ~~rates~~rate yields in 2010 compared ~~with~~to 2009. Interest income was $13 million for the ~~prior year.~~nine months ended September 30, 2010 and 2009. Interest expense ofwas $60 million in the ~~second~~third quarter of 2010 ~~decreased $5~~compared with $59 million ~~from~~for the same period in the prior year. ~~This~~Interest expense was $180 million for the nine months ended September 30, 2010 and 2009. In September 2010, MMC used a portion of the proceeds from the sale of Kroll to fund the maturity of $550 million of senior notes. As a result, interest expense should decrease ~~is primarily due to lower average debt from a note that matured~~starting in ~~June 2009.~~the fourth quarter of 2010.

Investment Income (Loss)

Net investment ~~income~~loss in the ~~second~~third quarter of 2010 was ~~$18~~$2 million due to mark-to-market declines in our private equity investments. This compares with investment gains of $22 million in the third quarter of 2009 primarily due to mark-to-market increases on private equity ~~investments. This compares with investment losses of $32 million in the second quarter of 2009 primarily due to mark-to-market decreases on private equity~~ fund investments. For the ~~six~~nine months of 2010, investment income was ~~$26~~$24 million compared with ~~$47~~$25 million of losses in the prior period.

Income Taxes

MMC reported ~~a net income~~an effective tax ~~benefit~~rate of ~~$60 million~~30.0% in continuing operations in the ~~second~~third quarter of ~~2010 on a pretax loss of $89 million, an~~2010. The 20.8% effective tax rate for the first nine months of ~~67.4%.

Excluding the impact of the Alaska settlement, the effective tax rate for the quarter was 32.3%. The 14.9% effective tax rate for the first six months of 2010 also primarily reflects the benefit associated with the Alaska settlement. Excluding the effect of the settlement, the effective tax rate for the first ~~six~~nine months was ~~29.5%~~29.6%. ~~The increase in effective~~

In the third quarter of 2009 MMC recorded a tax ~~rates compared to 2009, excluding the Alaska settlement, primarily reflects~~benefit of $46 million on pretax income of $161 million. This includes a ~~change~~net benefit of $95 million resulting from a decrease in the ~~worldwide mix~~liability for unrecognized tax benefits and accrued interest related to prior tax years as a result of ~~earnings.~~

~~The combination~~ Excluding the effect of ~~ordinary income and related tax, which MMC is able to reasonably estimate, with certain items which cannot be estimated and therefore are reported~~the benefit from the decrease in the ~~interim period~~liability for unrecognized tax benefits recognized in which they occur, results in highly variable effective tax rates that do not represent long term operating trends. The items which cannot be estimated include non-deductible goodwill impairments and accruals for severance, restructuring, and professional liability. We expectthe third quarter, the effective tax rate ~~to continue to be highly variable over the short term as items that cannot be estimated continue, and then to moderate.~~

~~Nevertheless, we expect the effective tax rate to remain significantly variable~~ for the ~~foreseeable future. The rate is sensitive to the geographic mix and repatriation~~first nine months of MMC’s earnings, which may have a favorable or unfavorable impact on the rate. Losses in certain jurisdictions cannot be offset by earnings from other operations, and may require valuation allowances affecting the 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.2009 was 28.1%.

Changes in tax laws or tax rulings may have a significant adverse impact on our effective tax rate. For example, proposals for fundamental U.S. international tax reform, such as the recent proposal by President Obama’s Administration, if enacted, could have a significant adverse impact on the effective tax rate.

A $265 million deferred tax benefit was recorded in discontinued operations during the second quarter of 2010 to establish a deferred tax asset in connection with classifying Kroll as a discontinued operation. MMC’s tax basis in its investment in the stock of Kroll ~~exceeds~~exceeded the recorded amount primarily as a result of prior impairments of goodwill recognized for financial reporting, but not for tax. Prior to the second quarter of 2010, ~~the~~a tax benefit ~~was~~had not been recorded for this temporary difference because it was not apparent in the foreseeable future that it would reverse in a transaction that would result in a tax benefit. Since Kroll ~~was classified~~met the criteria for classification as a discontinued operation in the second quarter of ~~2010. ASC 740-30-25-10 provides~~2010, MMC determined that ~~deciding that a subsidiary meets~~it had the requirements for measurement and display as a discontinued operation makes it apparent that the temporary difference will reverse in the foreseeable future. Entering into an agreement to sell the stock of Kroll in the second quarter of 2010, coupled with MMC’s ability to carry back the capital loss realized against ~~its 2007~~prior realized capital ~~gain from the sale of Putnam, made it apparent that~~gains. Therefore, a $265 million deferred tax benefit was recorded in discontinued operations in the ~~foreseeable future the temporary difference would reverse in~~second quarter of 2010 to establish a ~~transaction structure that would realize a~~deferred tax ~~benefit.~~asset.

Dispositions

On August 3, 2010, MMC completed its sale of Kroll to Altegrity for cash proceeds of $1.13 billion. In the first quarter of 2010, Kroll completed the sale of KLS. The account balances and activities of Kroll and KLS ~~were~~have been segregated and reported as discontinued operations in the accompanying consolidated balance sheets at ~~June 30, 2010 and~~ December 31, ~~2009~~2009. The gain on the sale of Kroll and ~~the accompanying consolidated statements of income for the three-month~~related tax benefits and ~~six-month periods ended June 30, 2010 and 2009. The~~the after-tax loss on ~~this disposal is~~the sale of KLS, along with Kroll’s and KLS’s 2010 and comparative results of operations are included in ~~discontinued operations in 2010. The operating results of KLS have been reclassified into~~ discontinued operations.

In the second quarter of 2009, Kroll completed the sale of Kroll Government Services (“KGS”). The financial results of KGS for ~~the second quarter of~~ 2009 are included in discontinued operations. Discontinued operations in ~~the second quarter of~~ 2010 and 2009 also includes the accretion of interest related to an indemnity for uncertain tax positions provided as part of the purchase by Great West Lifeco Inc. of Putnam Investments Trust from MMC in August 2007.

The income tax credit related to the disposal of discontinued operations for the nine months ended September 30, 2010 primarily represents the recognition of tax benefits recorded in the second quarter when MMC concluded the sale of Kroll was probable. The nine months of 2010 also includes a tax provision of $36 million on the sale of KLS.

Liquidity and Capital Resources

Operating Cash Flows

MMC provided ~~$272~~$50 million of cash from operations for the ~~six~~nine months ended ~~June~~September 30, 2010, compared with ~~$236~~$405 million ~~used~~provided for the same period in 2009. These amounts reflect the net income of MMC during those periods, excluding gains or losses from investments and from the disposition of businesses, adjusted for non-cash ~~charges,~~items, and changes in working capital which relate primarily to the timing of payments of accrued liabilities or receipts of assets. Cash generated from the disposition of businesses is included in investing cash flows.

On June 11, 2010, MMC ~~announced that it has~~ resolved the litigation brought by the Alaska Retirement Management Board ~~(ARMB)~~(“ARMB”) on behalf of two Alaska benefit plans against Mercer, relating to work in the period 1992 to 2004. Under the terms of the settlement agreement, Mercer ~~has agreed to pay~~paid $500 million, of which $100 million ~~will be~~is covered by insurance. ~~The Company expects to fund this payment from cash on hand in the third quarter of 2010.~~ The Company has recorded a tax benefit of ~~$265~~$267 million related to the disposition of Kroll and a $160 million tax benefit related to the cost of the Alaska Settlement. MMC expects to realize approximately 80% of these tax benefits within the next twelve months.

During the third quarter of 2010, MMC contributed $200 million to the Marsh & McLennan Companies U.S. Retirement Plan. MMC will realize a tax benefit on this contribution of approximately $70 million.

Financing Cash Flows

Net cash used for financing activities was ~~$265~~$931 million for the period ended ~~June~~September 30, 2010 compared with ~~$238~~$358 million ~~provided~~used for the same period in 2009.

MMC paid dividends on its common shares of ~~$221~~$333 million ($~~0.40~~0.60 per share) during the first ~~six~~nine months of 2010, as compared with ~~$207~~$322 million ($~~0.40~~0.60 per share) during the first ~~six~~nine months of 2009.

The Company used a portion of the cash received from the Kroll disposition to fund the maturity of $550 million of senior notes in the third quarter of 2010.

On September 15, 2010, MMC’s Board of Directors authorized a $500 million share repurchase program.

In the first quarter of 2009, MMC issued $400 million of 9.25% ten-year fixed rate senior notes to refinance the senior notes that matured in June 2009.

~~The Company expects to use cash received from the Kroll disposition to fund the maturity of $550 million of senior notes in the third quarter of 2010.~~

~~- 43 -~~

On October 23, 2009, MMC and certain of its foreign subsidiaries entered into a new $1.0 billion multi-currency three-year unsecured revolving credit facility, which replaced the $1.2 billion facility that was previously in place. The interest rate on this facility varies based upon MMC’s credit ratings and MMC’s credit default swap levels subject to floors and caps. The facility requires MMC to maintain certain coverage and leverage ratios which are tested quarterly. There were no borrowings outstanding under this facility at ~~June~~September 30, 2010.

In the first quarter of 2010, MMC paid deferred purchase consideration of $15 million related to the purchase in 2009 of the minority interest of a previously controlled entity.

MMC’s senior debt is currently rated Baa2 by Moody’s and BBB- by Standard & Poor’s. MMC’s short-term debt is currently rated P-2 by Moody’s and A-3 by Standard & Poor’s. MMC carries a stable outlook from Moody’s and a negative outlook from Standard & Poor’s.

The major credit rating agencies periodically evaluate MMC’s creditworthiness. Any downgrade in MMC’s ratings from current levels could increase its long-term financing costs, as lenders can be expected to consult such ratings in determining the terms on which credit is extended to MMC in the future. Additionally, counterparties to certain agreements, including derivative financial instruments, may require additional security or other changes in business terms if MMC’s credit ratings are downgraded. Accordingly, any downgrade in MMC’s credit ratings from current levels could adversely affect MMC’s results of operations and ability to pursue business opportunities.

Investing Cash Flows

Cash ~~used for~~provided by investing activities amounted to ~~$153~~$817 million in the first ~~six~~nine months of 2010, compared with ~~$60~~$114 million used for the same period in 2009.

MMC made ~~four~~six acquisitions during the first ~~six~~nine months of 2010. Cash used for these acquisitions, net of cash acquired, was approximately ~~$164~~$222 million compared with $6$4 million used for acquisitions in 2009. In addition, MMC issued approximately ~~7.4~~7.6 million shares of common stock with an acquisition date value of ~~$178~~$183 million, and recorded a liability of ~~$55~~$65 million for estimated contingent purchase consideration related to the acquisitions completed in the ~~second quarter~~first nine months of 2010. In 2010, MMC also paid ~~$14~~$21 million of deferred purchase consideration, $3 million for other intangible assets and $2 million of contingent purchase consideration related to acquisitions made in prior years. Remaining deferred cash payments of ~~$209~~$207 million for acquisitions completed in the ~~second~~third quarter of 2010 and in prior years are recorded in accounts payable and accrued liabilities or other liabilities in the consolidated balance sheet at ~~June~~September 30, 2010. ~~Cash generated from the disposition~~MMC paid contingent consideration of ~~KLS was $110~~$3 million ~~in the second quarter of 2010 compared to $70 million related to the disposition of KGS~~ in 2009.

MMC’s additions to fixed assets and capitalized software amounted to ~~$143~~$193 million in the first nine months of 2010 and $209 million for ~~both six month periods ended 2010 and~~the same period in 2009, primarily related to computer equipment purchases, the refurbishing and modernizing of office facilities and software development costs.

The company received $1.13 billion from its disposition of Kroll, which closed on August 3, ~~2010. The cash~~2010 and $110 million from the ~~Kroll~~ disposition ~~is not included~~of KLS which closed in the ~~consolidated statement~~second quarter of ~~cash flows for~~2010. In 2009, MMC received $70 million related to the ~~period ended June 30, 2010.~~disposition of KGS.

During the first nine months of 2010, MMC received $31 million of proceeds from the sale of investments and a $27 million distribution from its investment in a private equity fund.

MMC has committed to potential future investments of approximately $81 million in connection with its investments in Trident II and other funds managed by Stone Point Capital. The majority of MMC’s investment commitments for funds managed by Stone Point are related to Trident II, the investment period for which is now closed for new investments and follow-on investments. Any remaining capital calls for Trident II would relate to management fees or other partnership expenses, if necessary. Significant future capital calls related to Trident II are not expected. Although it is anticipated that Trident II will be harvesting its remaining portfolio, the timing of any portfolio company sales and capital distributions is unknown and not controlled by MMC.

Commitments and Obligations

MMC’s contractual obligations of the types identified in the table below were of the following amounts as of ~~June~~September 30, 2010 (dollars in millions):


	Payment due by Period										Payment due by Period

The above does not include unrecognized tax benefits of ~~$211~~$204 million as MMC is unable to reasonably predict the timing of settlement of these liabilities, other than approximately ~~$15~~$10 million that may become payable within one year. The above does not include liabilities established relating to guarantees from indemnities as MMC is unable to reasonably predict the timing of settlement of these liabilities. The above does not include pension liabilities of ~~$887~~$693 million 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.

New Accounting Pronouncements

Note 18 to the consolidated financial statements contains a discussion of recently issued accounting pronouncements and their impact or potential future impact on MMC’s financial results, if determinable.

Item 3.

Qualitative and Quantitative Disclosures About Market Risk

Market Risk and Credit Risk

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

Interest Rate Risk and Credit Risk

MMC has historically managed its interest rate exposures by utilizing both variable and fixed rate borrowings to finance MMC’s asset base. In past years, MMC has had some variable rate borrowings in its debt portfolio and has also utilized interest rate swaps to convert a portion of its fixed rate borrowings to variable rate. Currently, virtually all of MMC’s borrowings are fixed rate borrowings.

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

In addition to interest rate risk, our cash investments and fiduciary fund investments are subject to potential loss of value due to counterparty credit risk. To minimize this risk, MMC 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 counterparty limits assigned based primarily on credit rating and type of investment. MMC carefully monitors its cash and fiduciary fund investments and will further restrict the portfolio as appropriate to market conditions. The majority of cash and fiduciary fund investments are invested in short-term bank deposits and liquid money market funds.

Foreign Currency Risk

The translated values of revenue and expense from MMC’s international operations are subject to fluctuations due to changes in currency exchange rates. Forward contracts and options are periodically utilized by MMC to limit foreign currency exchange rate exposure on net income and cash flows for specific, clearly defined transactions arising in the ordinary course of its business.

Equity Price Risk

MMC holds investments in both public and private companies as well as certain private equity funds managed by Stone Point Capital. Publicly traded investments of ~~$24~~$23 million are classified as available for sale under ASC Topic No. 320 (“Investments – Debt and Equity Securities”). Non-publicly traded investments of $38 million are accounted for using the cost method and $180 million are accounted for under ASC Topic No. 323 (“Investments – Equity Method and Joint Ventures”). The investments that are classified as available for sale or that are not publicly traded are subject to risk of changes in market value, which if determined to be other-than-temporary, could result in realized impairment losses. MMC periodically reviews the carrying value of such investments to determine if any valuation adjustments are appropriate under the applicable accounting pronouncements.

Other

A significant number of lawsuits and regulatory proceedings are pending. See Note 16 to the consolidated financial statements included elsewhere in this report.
