INDEPENDENT AUDITORS' REPORT



To Marsh & McLennan Companies Stock Investment Plan Committee:


We have audited the accompanying statements of net assets available for benefits
of the Marsh & McLennan Companies Stock Investment Plan (the "Plan") as of June
30, 2002 and 2001, and the related statement of changes in net assets available
for benefits for the year then ended June 30, 2002. These financial statements
are the responsibility of the Plan's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

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

In our opinion, such financial statements present fairly, in all material
respects, information regarding the Plan's net assets available for benefits as
of June 30, 2002 and 2001 and the changes in net assets available for benefits
for the year ended June 30, 2002 in conformity with accounting principles
generally accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules listed in the
table of contents are presented for purposes of additional analysis and are not
a required part of the basic financial statements but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. These schedules are the responsibility of the Plan's management. Such
schedules have been subjected to the auditing procedures applied in the audit of
the basic 2002 financial statements and, in our opinion, are fairly stated in
all material respects when considered in relation to the basic financial
statements taken as a whole.

                MARSH & McLENNAN COMPANIES STOCK INVESTMENT PLAN
                          NOTES TO FINANCIAL STATEMENTS
                             JUNE 30, 2002 and 2001


   (1) Description of the Plan:
       -----------------------

       The Marsh & McLennan Companies Stock Investment Plan (the "Plan") is a
       defined contribution Employee Stock Ownership Plan which allows
       participants to contribute through payroll deductions from 1% to 15% of
       their salary, on a before and/or after-tax basis. Marsh & McLennan
       Companies, Inc. ("MMC" or the "Company") matches up to the first six
       percent of participants' before and/or after tax contributions in the
       following percentages:

         o  71-2/3% for each participant who elects to receive dividends on
            their MMC shares as cash payments each quarter (100% for those
            participants age 55 or whose age plus years of plan participation
            equals at least sixty-five).

         o  66-2/3% for each plan  participant  who elects not to receive the
            cash dividends (95% for those  participants  age 55 or whose age
            plus years of plan participation equals at least sixty-five).

       The increase over the basic match must be invested in the Company stock
       fund. Participants who are age 55 or whose age plus years of plan
       participation equals at least sixty-five may diversify their contribution
       and accumulated balance among the MMC Stock Fund, a Fixed Income Fund and
       various Putnam mutual funds. In addition, Company basic matching
       contributions are invested the same as participants' contributions. The
       Company's matching contributions to a participant are suspended for 12
       months if the participant makes certain in-service withdrawals from their
       Account. Employee and Company contributions are subject to certain
       limitations in accordance with Federal Income Tax Regulations. For
       employees hired on and after January 1, 1998, the Plan includes a vesting
       schedule for Company matching contributions. These employees shall vest
       33% in such contributions after three years of service, 67% after four
       years of service and 100% after five years of service.

       In April 2002 and May 2002, $25,286,480 and $5,398,001 were transferred
       into the Plan from the KVI Profit Sharing and 401(k) Plan and the J&H/KVI
       Profit Sharing Plan, respectively. In August 2001, $1,113,433 was
       transferred into the Plan from CODA, Inc. 401(k) Retirement & Savings
       Plan.

       In the fourth quarter of 1998, the Company consummated a business
       combination with Sedgwick Group plc ("Sedgwick"). Former employees of
       Sedgwick became eligible to participate in the Plan effective January 1,
       2000. Participants' balances in the Sedgwick Savings & Investment Plan
       were transferred into the Plan on December 2, 2002.

       The trustee, Bankers Trust Company, is responsible for maintaining the
       assets of the Plan, making distribution payments as directed by the
       Company and generally performing all other acts deemed necessary or
       proper to fulfill its responsibility as set forth in the Trust Agreement.

       Certain administrative functions are performed by employees of the
       Company or its subsidiaries. All such costs as well as administrative
       expenses for the Trustee's fees are paid directly by the Company. The
       employee benefits handbook, containing Plan information and documents
       constituting part of a Prospectus, is provided to each participant in the
       Plan.







   (2) Summary of Significant Accounting Policies:
       ------------------------------------------

       Basis of accounting
       -------------------
       The accompanying financial statements have been prepared in accordance
       with accounting principles generally accepted in the United States of
       America.

       Use of estimates
       ----------------
       The preparation of financial statements in conformity with accounting
       principles generally accepted in the United States of America requires
       management to make estimates and assumptions that affect the reported
       amounts of net assets available for benefits and changes therein.
       Actual results could differ from those estimates. The Plan utilizes
       various investment instruments. Investment securities, in general, are
       exposed to various risks, such as interest rate, credit, and overall
       market volatility. Due to the level of risk associated with certain
       investment securities, it is reasonably possible that changes in the
       values of investment securities will occur in the near term and that
       such changes could materially affect the amounts reported in the
       statement of net assets available for plan benefits.

       Cash and cash equivalents
       -------------------------
       Cash and cash equivalents primarily consist of interest bearing money
       market investments, which are available on demand.

       Investments
       -----------
       The common stock of Marsh & McLennan Companies, Inc. and shares of
       Putnam Mutual Funds are reflected in the accompanying statements of
       net assets available for benefits at quoted market prices.

       The Plan's Fixed Income Fund, which consists of guaranteed insurance
       contracts and group annuity contracts, has been presented in the
       financial statements at contract value, which approximates fair market
       value. The investments in this fund are valued at contract value,
       which is cost plus accrued interest, and are guaranteed by the issuing
       institution as to principal and interest. The average yield for these
       investment contracts was approximately 6.2% for the year ended June
       30, 2002.

       The following table presents the market values of investments that
       represent 5% or more of the Plan's net assets at the beginning of the
       plan-year:

        The plan offers a program that is both participant and non-participant
        directed. All non-participant directed contributions are invested in
        the Marsh & McLennan Companies Stock Fund. The net assets as of June
        30, 2002 and 2001 and changes in net assets relating to the Company
        stock fund for the year ended June 30, 2002 are as follows:

   (3) Related party transactions:
       --------------------------

       The Putnam Investors Fund, Inc., the Putnam Fund for Growth & Income, the
       Putnam Voyager Fund, the Putnam Global Growth Fund, the Putnam New
       Opportunities Fund, the George Putnam Fund of Boston, the Putnam S&P 500
       Index Fund and the Putnam Bond Index Fund are managed by Putnam
       Investments, LLC, a subsidiary of the Company.

   (4) Loans receivable-participants:
       -----------------------------

       Plan participants may borrow funds from their account subject to certain
       limits and conditions. Outstanding loans, which are secured by the
       participants' interest in the Plan, are generally repaid through payroll
       deductions or, at the option of the participant, the total outstanding
       balance may be prepaid anytime after the completion of 12 months of loan
       repayments. Participants' loan repayments and any interest due are paid
       into the participants' account.

       New loans to participants amounted to $13,437,974 and $13,935,507 for the
       years ended June 30, 2002 and 2001, respectively, and repayments from
       participants, including interest, amounted to $15,007,677 and $14,767,980
       respectively.

   (5) Income Tax Status:
       -----------------

       The Internal Revenue Service has determined and informed the Company by a
       letter dated January 28, 2002, that the Plan is designed in accordance
       with applicable sections of the Internal Revenue Code ("IRC"). The Plan
       has been amended since receiving the determination letter. However, the
       Plan Administrator and the Plan's tax counsel believe that the Plan is
       currently being operated in compliance with the applicable requirements
       of the IRC.

   (6) Payment of Benefits:
       -------------------

       Benefit payments to participants are recorded upon distribution. Amounts
       allocated to accounts of persons who have elected to withdraw from the
       Plan but have not yet been paid were $243,799 at June 30, 2002. These
       amounts have not been recorded as liabilities in the accompanying
       financial statements.

   (7) Supporting Schedules:
       --------------------

       The detail of assets held for investment as of June 30, 2002 is provided
       on Schedule I.

       The summary of transactions occurring during the year ended June 30, 2002
       representing more than 5% of the Plan's net assets as of July 1, 2001 is
       reportable under the Department of Labor Regulation 2520.103-6 and is
       presented on Schedule II.

   (8) Subsequent Event:
       ----------------

       Effective July 1, 2002, the vesting schedule for all participants was
       changed to 20% after two years of service, 40% after three years of
       service, 67% after four years of service and 100% after five years of
       service.
