REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Participants of the Putnam Investments
Profit Sharing Retirement Plan:

We have audited the accompanying statements of net assets available for
benefits of the Putnam Investments Profit Sharing Retirement Plan (the
"Plan") as of December 31, 2003 and 2002, and the related statements of
changes in net assets available for benefits for the years then ended.
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 the standards of the Public
Company Accounting Oversight Board (United States).  Those standards
require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all
material respects, the net assets available for benefits of the Plan as
of December 31, 2003 and 2002, and the changes in net assets available
for benefits for the years then ended 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 schedule
listed in the Table of Contents is presented for the purpose of
additional analysis and is not a required part of the basic 2003
financial statements but is 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. This schedule
is the responsibility of the Plan's management. Such schedule has been
subjected to the auditing procedures applied in our audit of the basic
2003 financial statements and, in our opinion, is fairly stated in all
material respects when considered in relation to the basic 2003
financial statements taken as a whole.

PUTNAM INVESTMENTS
PROFIT SHARING RETIREMENT PLAN

NOTES TO FINANCIAL STATEMENTS
------------------------------------------------------------------------------

1. DESCRIPTION OF THE PLAN

The following description of the Putnam Investments Profit Sharing
Retirement Plan (the "Plan") is provided for general information
purposes only. Participants should refer to the Plan document for a more
complete description of the Plan's provisions.

General -- The Plan is a defined contribution plan sponsored by Putnam
Investments LLC ("Putnam") and its subsidiaries (the "Company"). Putnam
is a wholly owned subsidiary of Putnam Investments Trust, which is
ultimately a majority-owned subsidiary of Marsh & McLennan Companies,
Inc. ("MMC"). The Plan is for the benefit of the Company's employees and
is intended to qualify as a profit-sharing plan under Section 401(a) of
the Internal Revenue Code (the "Code") and to constitute a qualified
cash or deferred arrangement under Section 401(k) of the Code. The Plan
document was amended on November 18th, 2003 to identify the Benefits
administration committee of MMC as the Plan administrator. The Plan
document was also amended and restated on January 1, 2001 to comply with
the applicable provisions of tax acts referred to as GUST. The Plan is
subject to the provisions of the Employee Retirement Income Security Act
of 1974 ("ERISA").

An employee is eligible to become a participant under the profit-sharing
portion of the Plan upon the completion of 12 months of service. An
employee is eligible to become a participant in the salary-deferral
portion of the Plan upon commencement of employment. A participant must
be employed on the last day of the Plan's fiscal year (December 31) to
be eligible for his or her portion of the Company's contribution for
that year.

Contributions -- Company contributions are determined at the discretion of
the Company's Board of Directors. Contributions may not exceed the
amount permitted as a deduction under the applicable provisions of the
Code. During the years ended December 31, 2003 and 2002, the Company
contributed 15% of eligible compensation.

It is the intention of the Trustees that the salary deferral portion of
the Plan be qualified under Section 401(k) of the Code. The terms of the
salary savings agreement provide that the participants' earnings
contribution to the Plan will be deducted from their payroll and that
the Company shall contribute this amount to the Plan on behalf of the
participants. Unless otherwise directed by the employee, all new
employees contribute 3% of their total earnings to the salary-deferred
portion of the Plan. The market value of assets relating to the salary
savings program at December 31, 2003 and 2002 was $115,778,720 and
$83,898,552, respectively.

Voluntary employee contributions are accepted within certain limits as
defined in the Plan. Participants making contributions are not allowed
to withdraw any appreciation on such contributions before termination of
employment but may withdraw their contributions subject to certain
restrictions.

Investment Programs -- The Plan allows each participant to elect to have
participant contributions, Company contributions and reallocated
forfeitures invested in one or more of the following authorized
investment vehicles:

(1) Any one or a combination of the open-end management investment
companies, excluding tax-exempt income funds, for which a subsidiary of
Putnam acts as an investment adviser ("Putnam-sponsored mutual funds").

(2) Prior to January 1997, any one or a combination of contracts with
insurance companies which guarantee principal and interest at a fixed
rate. Subsequent to January 1997, guaranteed investment contract
products are offered through the investment in the Putnam Fiduciary
Trust Company Stable Value Fund.

(3) MMC common stock (MMC is the parent company of Putnam).

(4) Other investment options approved by the Board of Directors of
Putnam, the trustees of the Plan (the "Trustees"), and the chief
executive officer of MMC. There were no investments in this option at
December 31, 2003 or 2002.

Participant and Company contributions and forfeitures must generally be
allocated with apportionments to be no less than 1% per investment.

With proper notification, participants may elect to change their
investment in either their participation or voluntary accounts up to
once a day.

Vesting -- The vesting of Company contributions is as follows:

                                                            Vested Interest
Years of continuous service:
Less than two                                                    None
Two but less than three                                           25%
Three but less than four                                          50%
Four but less than five                                           75%
Five or more                                                     100%
If a participant reaches age 59?, dies, or becomes disabled      100%

Participants are automatically fully vested in their voluntary and
rollover contributions.

Forfeitures -- Forfeitures of invested Company contributions are used to
reduce future Company contributions one year after the fiscal year in
which the forfeitures occur. At December 31, 2003 and 2002, forfeited
non-vested accounts totaled $1,569,495 and $1,265,721, respectively.
Reduction of Company contributions amounted to $1,265,721 and $1,644,468
in 2003 and 2002, respectively, for forfeitures that occurred in 2002
and 2001, respectively.

Participant Accounts -- Individual accounts are maintained for each Plan
participant. Each participant's account is credited with the
participant's contribution, the Company's contribution, and allocations
of Plan earnings, and charged with withdrawals and an allocation of Plan
losses. Allocations are based on participant earnings or account
balances, as defined. The benefit to which a participant is entitled is
the benefit that can be provided from the participant's vested account.

Company contributions are allocated annually based on a uniform
percentage of eligible earnings per participant.

Payment of Benefits -- Distributions are based on the vested portion of the
participant's account valuation as of the liquidation date coinciding
with or following the next valuation date after the individual ceases to
be a participant. Upon participant request, such distributions are made
within a reasonable period after the individual ceases to be a
participant, but not later than 60 days after the close of the fiscal
year. The Plan generally allows terminated participants to maintain
their accounts in the Plan, but such accounts do not share in
contributions and forfeiture reallocations. The value of these accounts
will continue to be determined each business day.

Participant Loans -- Upon the approval of the Retirement Savings Plan
Committee, appointed by the Plan administrator, participants of the Plan
may borrow from their accounts, to alleviate financial need as defined
by the Plan, an amount which, when added to all other loans to the
participant, would not exceed the lesser of (1) a maximum borrowing
limit of $50,000 or (2) 50% of the vested balance of the participant's
account. All loans shall be secured by the participant's account and
will be repaid through payroll deductions according to a fixed repayment
schedule which includes interest at a rate equal to the prime rate at
the time the loan originated. Loans outstanding at December 31, 2003 and
2002 were $10,611,759 and $8,517,015, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Method of Accounting -- The accompanying financial statements of the Plan
have been prepared on the accrual basis of accounting in accordance with
accounting principles generally accepted in the United States of
America. Certain prior-year amounts have been reclassified to conform to
the current-year presentation.

Estimates -- The preparation of financial statements in conformity with
accounting principles generally accepted in the United States of America
requires the Plan's 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
financial statements.

Investment Valuation and Income Recognition -- The Plan's investments are
stated at fair value except for its benefit-responsive investment
contracts, which are valued at contract value. Quoted market prices are
used to value investments. Shares of mutual funds are valued at the net
asset value of shares held by the Plan at year-end. Investment
transactions are recorded on the trade-date basis. Dividend income is
recorded on the ex-dividend date. Interest income is recorded as earned.

Administrative Expenses--Expenses of the Plan have been paid by the
Company, but such payment is at the Company's discretion.

Benefits--Benefits to participants are recorded when paid.

3. INVESTMENTS

Investments that represent 5% or more of the Plan's net assets available
for benefits at December 31 are as follows:

                                                      2003           2002

Putnam International Equity Fund                24,098,719     18,711,029

During the years ended December 31, the Plan's investments (including
gains and losses on investments bought and sold, as well as held, during
the year) appreciated (depreciated) in value as follows:

                                                      2003           2002

Investments at fair value, based on quoted
market prices:
Putnam-sponsored mutual funds                  $72,878,679   $(67,748,445)
MMC common stock, 343,778 and 323,311
shares, respectively                               862,907     (1,939,275)

Total                                          $73,741,586   $(69,687,720)

4. PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the
right under the Plan to discontinue its contributions at any time and to
terminate the Plan subject to the provisions of ERISA. In the event of
Plan termination, participants will become 100% vested in their
accounts.

5. SUBSEQUENT DISTRIBUTIONS

At December 31, 2003 and 2002, amounts allocated to accounts of persons
who have elected to withdraw from the Plan but have not yet been paid
were $1,646,793 and $1,017,871, respectively. These amounts by
investment type are as follows:

Source                                                2003           2002

Mutual funds                                    $1,529,873       $900,652
Stable Value Fund -- guaranteed
investment products                                 83,844         85,159
MMC common stock*                                   33,076         32,060

Total                                           $1,646,793     $1,017,871

*Putnam and MMC are parties-in-interest to the Plan.

6. TAX STATUS OF THE PLAN

The Plan obtained its latest determination letter on December 6, 2002 in
which the Internal Revenue Service stated that the Plan, as then
designed, was in compliance with the applicable requirements of the
Code. The Plan has been amended since receiving the determination
letter, however the Plan administrator believes that the Plan is
currently designed and being operated in compliance with the applicable
requirements of the Code. Accordingly, no provision for income taxes has
been included in the Plan's financial statements.

7. RELATED-PARTY TRANSACTIONS

Certain Plan investments are shares of Putnam-sponsored mutual funds and
collective trust. Putnam is the Plan sponsor as defined by the Plan, and
therefore these transactions qualify as party-in-interest transactions.
Fees paid by the Plan for investment management services were included
as a reduction of the return earned on each fund.

At December 31, 2003 and 2002, the Plan held 343,778 and 323,311 shares,
respectively, of common stock of MMC, the parent company of the
sponsoring employer, with a cost basis of $14,090,462 and $13,243,193,
respectively, and with a fair value of $16,463,546 and $14,940,179,
respectively. During the years ended December 31, 2003 and 2002, the
Plan recorded dividend income of $426,578 and $310,734, respectively.
