Dear Fellow Shareholder:

While we are pleased to report positive results for Putnam Massachusetts
Tax Exempt Income Fund for the fiscal year ended May 31, 2003, your
fund underperformed both its benchmark and its Lipper peer group
category average during the period. Details of these results can be
found on page 8.

Significant declines in state and local tax revenues, accompanied by
credit rating downgrades of both municipalities and the corporate
beneficiaries of industrial development bonds, continued to plague the
municipal bond market. The market was further tested as it faced the
challenge of digesting a record level of new issuance during the
period. In the following report, your fund's management team discusses
performance and strategy in detail and provides its view of prospects
for the fiscal year that has just begun.

In bringing you this news of your fund's performance, we would also like
to take the opportunity to tell you how much we appreciate your
confidence in Putnam. We will continue to do our utmost to deliver the
best possible results for your fund.

Respectfully yours,

/S/ JOHN A. HILL                   /S/ GEORGE PUTNAM, III

REPORT FROM FUND MANAGEMENT

FUND HIGHLIGHTS

* Putnam Massachusetts Tax Exempt Income Fund advanced strongly on an
  absolute basis for the year ended May 31, 2003, with class A shares
  returning 9.39% at net asset value and 4.15% at public offering price.

* Due to differences in portfolio composition, the fund underperformed
  its benchmark, the Lehman Municipal Bond Index, which returned 10.36%
  for the period.

* The fund's performance at net asset value slightly lagged the average
  return of 9.69% recorded by its Lipper category, Massachusetts Municipal
  Debt Funds, primarily due to the fund's more defensive positioning.

* See the Performance Summary on page 8 for complete fund performance,
  comparative performance, and Lipper data.

* PERFORMANCE COMMENTARY

In a year marked by historically high volatility in the capital markets,
Putnam Massachusetts Tax Exempt Income Fund  delivered strong returns at
net asset value. However, the fund's results lagged those of the Lehman
Municipal Bond Index and the average of its Lipper peer group, due
primarily to its slightly defensive positioning amid a bond market
rally.

A heavier weighting to longer-term bonds, greater exposure to bonds at
the lower end of the quality spectrum, and continued fiscal problems in
Massachusetts also contributed to the fund's underperformance versus its
benchmark, which is nationally diversified, includes only
investment-grade bonds, and has greater exposure to the shorter portions
of the yield curve. Shorter- and inter-mediate-maturity bonds fared well
amid a rally driven primarily by multiple short-term rate cuts by the
U.S. Federal Reserve Board.

Fund Profile

Putnam Massachusetts Tax Exempt Income Fund seeks to provide as high a
level of current income free from federal and Massachusetts state
personal income taxes, as believed to be consistent with the
preservation of capital. It may be suitable for Massachusetts investors
seeking tax-free income through a diversified portfolio of municipal
bonds issued primarily in Massachusetts.

* MARKET OVERVIEW

The first half of the fiscal year was generally positive for the
municipal bond market. In an environment marked by earnings
disappointments, economic weakness, and numerous allegations of
corporate malfeasance, investors sought the relative safety of
high-quality bonds. Increased demand for bonds pushed their prices
higher, and many of your fund's holdings benefited.

In the fiscal second half, several factors tempered municipal bond
performance, including significant declines in tax revenues and
subsequent downgrades in municipalities' credit quality. United
Airlines, which had provided credit backing for several municipal bond
issues, filed for bankruptcy in December, as had US Airways in the
months before. In late April, American Airlines narrowly avoided a
similar fate. Various segments of the electric power sector were under
duress as well. These difficulties put pressure on industrial
development bonds (IDBs), which are issued by municipalities but backed
by companies benefiting from the financing. Lastly, over $357 billion in
municipal bonds was issued in 2002 -- an all-time record. The California
Department of Water Resources had the single largest bond issue ever
brought to market. In 2003, supply continues to swell, and is on track
to exceed the previous year's record. These factors had a dampening
effect on municipal bond prices.

* STRATEGY OVERVIEW

Interest-rate sensitivity is an important consideration in the
management of bond portfolios. Duration, an investment term that
measures this sensitivity, can be calculated from bond coupon rates and
maturities. During the summer of 2002, we began implementing a defensive
strategy (shorter duration, less sensitivity) in anticipation of rising
interest rates. When interest rates rose in October, we returned to a
more neutral duration that drifted modestly shorter as the bond market
rally resumed -- a position that detracted from results. The fund's
duration profile would have moved even shorter had we not worked to
maintain it in the falling rate environment by swapping into discount
coupon and noncallable bonds.

In early 2003, tax-exempt municipal bonds offered investors almost the
same yield as comparable Treasury bonds. To take advantage of this
opportunity, we established a cross-market arbitrage position, in which
we bought intermediate-term municipal bonds and shorted 10-year Treasury
futures contracts. Our thesis was that if interest rates should rise
(causing bond prices to fall), the fund would have a loss on the
municipal bonds, and yet, potential gains on the Treasury futures
contracts could more than compensate for the loss. On the other hand, if
rates should fall (causing bond prices to rise), a loss on the Treasury
futures contracts could be mitigated by a gain on the municipal bonds.
We have seen the latter scenario begin to develop as municipal bonds
appreciated in price during the second half of the fiscal period.

* HOW KEY ALLOCATIONS AND HOLDINGS AFFECTED PERFORMANCE

The management team seeks to diversify the fund's holdings across the
credit quality spectrum, including selective exposure to lower-rated,
higher-yielding securities. During the period, the team's pursuit of
this strategy was impeded by the low supply of lower-rated bonds issued
in Massachusetts that met their investment criteria. Although the fund's
existing lower-rated bond holdings negatively affected performance
during the period -- due to investor preference for the safety of
higher-grade securities amid geopolitical uncertainty -- we believe a
diversified exposure across the quality spectrum is an appropriate
long-term strategy.

We believe the fund remains well diversified across the different
industry sectors of the municipal bond universe. However, given the
fluid nature of all sectors of the economy, some sectors represent
better value at different times. As this report was being written, we
believed that an improving investment climate made the hospital sector
attractive.

We've seen a number of uninsured hospital municipal bonds coming to
market in recent months. In addition to refinancing older, more
expensive debt at today's historically low interest rates, hospitals in
high-growth locations are requiring more resources to finance their
expansion to meet increasing patient demand. Furthermore, hospitals are
becoming more specialized and moving beyond their core medical services
by developing niches in such fields as cardiology or oncology. We look
for hospitals with dominant market positions, strong management teams,
and high-quality services. We've found some holdings in the Baa/BBB
credit quality range that meet our criteria, including bonds issued by
the Massachusetts Health and Education Facilities Authority for
Berkshire Health Systems. Despite a recent drop in operating income due
to higher labor costs, Berkshire Health Systems' dominant market share
in its region allows it to successfully offset its rising costs by
charging higher fees. Proceeds from the issue are being used to fund
construction and install a new computer system. The fund also purchased
bonds issued by Massachusetts Health and Education Facilities Authority
for Milford-Whitinsville Hospital. Like Berkshire, Milford has a
dominant market share in a desirable market area and is using the
proceeds from its issue for hospital renovation and construction.

*As a percentage of market value as of 5/31/03. A bond rated Baa/BBB or
 higher is considered investment grade. All ratings reflect Moody's and
 Standard & Poor's descriptions unless noted otherwise; percentages may
 include unrated bonds considered by Putnam Management to be of comparable
 quality. Ratings will vary over time.


Over the course of the fiscal year, the management team's decisions
about the types of municipal bonds to consider for purchase have been
affected by Massachusetts' declining economy. The governor and
legislature have worked hard to balance the budget at the state level,
which we believe means that state-issued general obligation bonds are
less likely to be downgraded and Moody's current credit watch for the
state is likely to be removed. However, the state government has
achieved a balanced budget at the expense of municipalities, a policy
that has affected the credit quality of local municipal bond issuers.
Local governments do not have the broad taxing power of the state
government and rely almost exclusively on property taxes for revenue.
While property values in Massachusetts have generally increased, despite
the economic slowdown, the rise in property tax revenue has not been
sufficient to offset cuts in state support. Therefore, we have taken
care to avoid uninsured local general obligation bonds. While we believe
that the economy is bottoming and see signs that development is picking
up again, we believe it will be a while before property taxes from
development have a positive impact on the bottom line of the state's
municipalities. Please note that all holdings discussed in this report
are subject to review in accordance with the fund's investment strategy
and may vary in the future.

* THE FUND'S MANAGEMENT TEAM

The fund is managed by the Putnam Tax Exempt Fixed-Income Team. The
members of the team are Richard Wyke (Portfolio Leader), Paul Drury
(Portfolio Member), David Hamlin (Portfolio Member), Susan McCormack
(Portfolio Member),  Joyce Dragone, and Jerome Jacobs.


THE OUTLOOK FOR YOUR FUND

The following commentary reflects anticipated developments that could
affect your fund over the next six months, as well as your management
team's plans for responding to them.

Our current outlook for the municipal bond market is cautiously
optimistic. The conflict with Iraq is largely over, and investors are
focused on economic concerns on the home front. While serious issues
remain, the level of uncertainty in the world seems to have eased a bit,
though we expect continued volatility.

Further, we believe that market yields may move higher in the near term
as a weakening dollar, Fed policy, the recently enacted tax cut package,
and growing federal budget deficits take effect. Accordingly, at the
very end of the period, we began the process of shifting back toward a
defensive duration.

Municipal budgets will continue to face significant pressures in the
months ahead. Governments will wrangle with how to implement costly
home-front protection measures while at the same time pushing tax cuts
to stimulate economic growth. Historically, improvement in the credit
quality of state and local governments has lagged a general economic
recovery, so we expect municipal credit quality to remain fragile for
some time to come.

Over the next few months, we believe the ratio of municipal-bond yields
to comparable Treasury yields is likely to return to more normal levels.
Accordingly, we will look for opportunities to reduce our cross-market
arbitrage position and we expect the fund will profit from the
transactions.

In our opinion, the market continues to offer attractive value  and
compelling risk/reward characteristics. With credit spreads remaining
very generous, we believe credit risk is worth taking in moderate
amounts. We believe municipal bonds could perform well relative to other
fixed-income sectors, because demand for the bonds is firm and supply
should moderate as rates move higher. We believe we have positioned your
fund to take advantage of the market's potential.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. The fund
concentrates its investments in one state and involves more risk than a
fund that invests more broadly.

Performance assumes reinvestment of distributions and does not account
for taxes. Returns at public offering price (POP) for class A and M
shares reflect a sales charge of 4.75% and 3.25%, respectively. Class B
share returns reflect the applicable contingent deferred sales charge
(CDSC), which is 5% in the first year, declining to 1% in the sixth
year, and is eliminated thereafter. Performance for class B and M shares
before their inception is derived from the historical performance of
class A shares, adjusted for the applicable sales charge (or CDSC) and
higher operating expenses for such shares. For a portion of the period,
this fund had limited expenses, without which returns would have been
lower.

TERMS AND DEFINITIONS

Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested
all distributions in the fund.

Net asset value (NAV) is the price, or value, of one share of a mutual
fund, without a sales charge. NAVs fluctuate with market conditions. The
NAV is calculated by dividing the net value of all the fund's assets by
the number of outstanding shares.

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the 4.75% maximum sales charge for class A
shares and 3.25% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time
of the redemption of class B shares and assumes redemption at the end of
the period. Your fund's class B CDSC declines from a 5% maximum during
the first year to 1% during the sixth year. After the sixth year, the
CDSC no longer applies.

Class A shares are generally subject to an initial sales charge and no
sales charge on redemption (except on certain redemptions of shares
bought without an initial sales charge).

Class B shares may be subject to a sales charge upon redemption.

Class M shares have a lower initial sales charge and a higher  12b-1 fee
than class A shares and no sales charge on redemption (except on certain
redemptions of shares bought without an initial sales charge).

PUTNAM'S POLICY ON CONFIDENTIALITY

In order to conduct business with our shareholders, we must obtain certain
personal  information such as account holders' addresses, telephone
numbers, Social Security numbers, and the names of their financial
advisors. We use this information to assign an account number and to help
us maintain accurate records of transactions and account balances.

It is our policy to protect the confidentiality of your information,
whether or not you  currently own shares of our funds, and in
particular, not to sell information about you or your accounts to
outside marketing firms. We have safeguards in place designed to prevent
unauthorized access to our computer systems and procedures to protect
personal information from unauthorized use.

Under certain circumstances, we share this information with outside
vendors who  provide services to us, such as mailing and proxy
solicitation. In those cases, the service providers enter into
confidentiality agreements with us, and we provide only the  information
necessary to process transactions and perform other services related to
 your account. We may also share this information with our Putnam
affiliates to service your account or provide you with information about
other Putnam products or services. It is also our policy to share
account information with your financial advisor, if you've  listed one
on your Putnam account.

If you would like clarification about our confidentiality policies or
have any questions or concerns, please don't hesitate to contact us at
1-800-225-1581, Monday through Friday, 8:30 a.m. to 7:00 p.m., or
Saturdays from 9:00 a.m. to 5:00 p.m. Eastern Time.


A GUIDE TO THE FINANCIAL STATEMENTS

These sections of the report, as well as the accompanying Notes,
preceded by the Report of independent accountants, constitute the fund's
financial statements.

The fund's portfolio  lists all the fund's investments and their values
as of the last day of the reporting period. Holdings are organized by
asset type and industry sector, country, or state to show areas of
concentration and diversification.

Statement of assets and liabilities  shows how the fund's net assets and
share price are determined. All investment and noninvestment assets are
added together.  Any unpaid expenses and other liabilities are
subtracted from this total. The result is divided by the number of
shares to determine the net asset value per share, which is calculated
separately for each class of shares. (For funds with preferred shares,
the amount subtracted from total assets includes the net assets
allocated to remarketed preferred shares.)

Statement of operations  shows the fund's net investment gain or loss.
This is done by first adding up all the fund's earnings -- from
dividends and interest income -- and subtracting its operating expenses
to determine net investment income (or loss).  Then, any net gain or
loss the fund realized on the sales of its holdings -- as well as any
unrealized gains or losses over the period -- is added to or subtracted
from the net investment result to determine the fund's net gain or loss
for the fiscal year.

Statement of changes in net assets  shows how the fund's net assets were
affected by distributions to shareholders and by changes in the number
of the fund's shares. It lists distributions and their sources (net
investment income or realized capital gains) over the current reporting
period and the most recent fiscal year-end. The distributions listed
here may not match the sources listed in the Statement of operations
because the distributions are determined on a tax basis and may be paid
in a different period from the one in which they were earned.

Financial highlights  provide an overview of the fund's investment
results,  per-share distributions, expense ratios, net investment income
ratios, and portfolio turnover in one summary table, reflecting the five
most recent reporting periods. In a semiannual report, the highlight
table also includes the current reporting period. For open-end funds, a
separate table is provided for each share class.


REPORT OF INDEPENDENT ACCOUNTANTS

To the Trustees and Shareholders of
Putnam Massachusetts Tax Exempt Income Fund

In our opinion, the accompanying statement of assets and liabilities,
including the fund's portfolio (except for bond ratings) and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial
position of Putnam Massachusetts Tax Exempt Income Fund (the "fund") at
May 31, 2003, and the results of its operations, the changes in its net
assets and the financial highlights for the periods indicated, in
conformity with accounting principles generally accepted in the United
States of America. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility
of the fund's management; our responsibility is to express an opinion on
these financial statements based on our audits. We conducted our audits
of these financial statements in accordance with auditing standards
generally accepted in the United States of America, which 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, assessing the
accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe
that our audits, which included confirmation of investments owned at May
31, 2003, by correspondence with the custodian, provide a reasonable
basis for our opinion.

      be the most recent ratings available at May 31, 2003 for the securities
      listed. Ratings are generally ascribed to securities at the time of

      "/P" and are not publicly rated. Ratings are not covered by the Report
      of independent accountants.

NOTES TO FINANCIAL STATEMENTS
May 31, 2003

Note 1
Significant accounting policies

Putnam Massachusetts Tax Exempt Income Fund (the "fund") is registered
under the Investment Company Act of 1940, as amended, as a diversified,
open-end management investment company. The fund seeks as high a level
of current income exempt from federal income tax and Massachusetts
personal income tax as Putnam Investment Management, LLC ("Putnam
Management"), the fund's manager, an indirect wholly-owned subsidiary of
Putnam, LLC, believes is consistent with preservation of capital by
investing primarily in a portfolio of investment-grade Massachusetts
tax-exempt securities with intermediate- to long-term maturities.

The fund offers class A, class B and class M shares. Class A shares are
sold with a maximum front-end sales charge of 4.75%. Class B shares, which
convert to class A shares after approximately eight years, do not pay a
front-end sales charge, but pay a higher ongoing distribution fee than
class A and class M shares, and are subject to a contingent deferred sales
charge, if those shares are redeemed within six years of purchase. Class M
shares are sold with a maximum front-end sales charge of 3.25% and pay an
ongoing distribution fee that is higher than class A but lower than class
B shares.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class
(including the distribution fees applicable to such class). Each class
votes as a class only with respect to its own distribution plan or other
matters on which a class vote is required by law or determined by the
Trustees. Shares of each class would receive their pro-rata share of the
net assets of the fund, if the fund were liquidated. In addition, the
Trustees declare separate dividends on each class of shares.

The following is a summary of significant accounting policies
consistently followed by the fund in the preparation of its financial
statements. The fund may be affected by economic and political
developments in the state of Massachusetts. The preparation of financial
statements is in conformity with accounting principles generally
accepted in the United States of America and requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities in the financial statements and the reported amounts of
increases and decreases in net assets from operations during the
reporting period. Actual results could differ from those estimates.

A) Security valuation Tax-exempt bonds and notes are valued on the basis
of valuations provided by an independent pricing service, approved by
the Trustees. Such services use information with respect to transactions
in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining value. Restricted securities are valued at fair value
following procedures approved by the Trustees. Such valuations and
procedures are reviewed periodically by the Trustees.

B) Security transactions and related investment income Security
transactions are recorded on the trade date (date the order to buy or
sell is executed). Gains or losses on securities sold are determined on
the identified cost basis.

Interest income is recorded on the accrual basis. All premiums/discounts
are amortized/accreted on a yield-to-maturity basis. The premium in
excess of the call price, if any, is amortized to the call date;
thereafter, any remaining premium is amortized to maturity.

C) Futures and options contracts The fund may use futures and options
contracts to hedge against changes in the values of securities the fund
owns or expects to purchase. The fund may also write options on securities
it owns or in which it may invest to increase its current returns.

The potential risk to the fund is that the change in value of futures
and options contracts may not correspond to the change in value of the
hedged instruments. In addition, losses may arise from changes in the
value of the underlying instruments, if there is an illiquid secondary
market for the contracts, or if the counterparty to the contract is
unable to perform. When the contract is closed, the fund records a
realized gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was
closed. Realized gains and losses on purchased options are included in
realized gains and losses on investment securities.

Futures contracts are valued at the quoted daily settlement prices
established by the exchange on which they trade. The fund and the broker
agree to exchange an amount of cash equal to the daily fluctuation in
the value of the futures contract. Such receipts or payments are known
as "variation margin." Exchange traded options are valued at the last
sale price, or if no sales are reported, the last bid price for
purchased options and the last ask price for written options. Options
traded over-the-counter are valued using prices supplied by dealers.
Futures and written option contracts outstanding at period end
are listed after The fund's portfolio.

D) Total return swap contracts The fund may enter into total return swap
contracts, which are arrangements to exchange a market linked return for
an interest payment, both based on a notional principal amount. To the
extent that the total return of the security or index underlying the
transaction exceeds or falls short of the offsetting interest rate
obligation, the fund will receive a payment from or make a payment to
the counterparty, respectively. Total return swap contracts are marked
to market daily based upon quotations from market makers and the change,
if any, is recorded as unrealized gain or loss. Payments received or
made at the end of the measurement period are recorded as realized gains
or losses. The fund could be exposed to credit or market risk due to
unfavorable changes in the fluctuation of interest rates or in the price
of the underlying security or index, the possibility that there is no
liquid market for these agreements or that the counterparty may default
on its obligation to perform. Total return swap contracts outstanding at
period end are listed after The fund's portfolio.

E) Line of credit The fund has entered into a committed line of credit
with certain banks. This line of credit agreement includes restrictions
that the fund maintain an asset coverage ratio of at least 300% and that
borrowings not exceed prospectus limitations. For the year ended May 31,
2003, the fund had no borrowings against the line of credit.

F) Federal taxes It is the policy of the fund to distribute all of its
income within the prescribed time and otherwise comply with the provisions
of the Internal Revenue Code applicable to regulated investment companies.
It is also the intention of the fund to distribute an amount sufficient to
avoid imposition of any excise tax under Section 4982 of the Internal
Revenue Code of 1986, as amended. Therefore, no provision has been made
for federal taxes on income, capital gains or unrealized appreciation on
securities held nor for excise tax on income and capital gains.

At May 31, 2003, the fund had a capital loss carryover of approximately
$3,612,000 available to the extent allowed by tax law to offset future
net capital gains, if any. The amount of the carryover and the
expiration dates are:

Loss Carryover    Expiration
- --------------    ------------------
      $358,000    May 31, 2007
     2,162,000    May 31, 2008
     1,092,000    May 31, 2009

G) Distributions to shareholders Income dividends are recorded daily by
the fund and are paid monthly. Distributions from capital gains, if any,
are recorded on the ex-dividend date and paid at least annually. The
amount and character of income and gains to be distributed are determined
in accordance with income tax regulations which may differ from generally
accepted accounting principles. These differences include temporary and
permanent differences of dividends payable, realized and unrealized gains
and losses on certain futures contracts, market discount and straddle-loss
deferrals. Reclassifications are made to the fund's capital accounts to
reflect income and gains available for distribution (or available capital
loss carryovers) under income tax regulations. For the year ended May 31,
2003, the fund reclassified $173,614 to increase undistributed net
investment income with an increase to accumulated net realized losses of
$173,614.

The tax basis components of distributable earnings and the federal tax
cost as of period end were as follows:

Unrealized appreciation                    $38,395,905
Unrealized depreciation                     (2,762,805)
                                    ------------------
Net unrealized appreciation                 35,633,100
Undistributed tax-exempt income              1,066,239
Undistributed ordinary income                  171,026
Capital loss carryforward                   (3,611,962)
Post-October loss                                   --

Cost for federal income
tax purposes                              $428,131,427


Note 2
Management fee, administrative
services and other transactions

Putnam Management is paid for management and investment advisory
services quarterly based on the average net assets of the fund. Such fee
is based on the lesser of (i) an annual rate of 0.50% of the average net
assets of the fund or (ii) the following annual rates expressed as a
percentage of the fund's average net assets: 0.60% of the first $500
million, 0.50% of the next $500 million, 0.45% of the next $500 million,
0.40% of the next $5 billion, 0.375% of the next $5 billion, 0.355% of
the next $5 billion, 0.34% of the next $5 billion and 0.33% thereafter.

The fund reimburses Putnam Management an allocated amount for the
compensation and related expenses of certain officers of the fund and
their staff who provide administrative services to the fund. The aggregate
amount of all such reimbursements is determined annually by the Trustees.

Custodial functions for the fund's assets are provided by Putnam
Fiduciary Trust Company (PFTC), a subsidiary of Putnam, LLC. Investor
servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.

The fund has entered into an arrangement with PFTC whereby credits
realized as a result of uninvested cash balances are used to reduce a
portion of the fund's expenses. For the year ended May 31, 2003, the
fund's expenses were reduced by $39,620 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $710 has been allocated to the fund, and an additional fee for
each Trustees meeting attended. Trustees receive additional fees for
attendance at certain committee meetings.

The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of
Trustees fees payable on or after July 1, 1995. The deferred fees remain
invested in certain Putnam funds until distribution in accordance with
the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as a Trustee for at least five years. Benefits under the Pension
Plan are equal to 50% of the Trustee's average total retainer and
meeting fees for the three years preceding retirement. Pension expense
for the fund is included in Compensation of Trustees in the Statement of
operations. Accrued pension liability is included in Payable for
compensation of Trustees in the Statement of assets and liabilities.

The fund has adopted distribution plans (the "Plans") with respect to
its class A, class B and class M shares pursuant to rule 12b-1 under the
Investment Company Act of 1940. The purpose of the Plans is to
compensate Putnam Retail Management, a wholly-owned subsidiary of
Putnam, LLC and Putnam Retail Management GP, Inc., for services provided
and expenses incurred by it in distributing shares of the fund. The
Plans provide for payments by the fund to Putnam Retail Management at an
annual rate of up to 0.35%, 1.00% and 1.00% of the average net assets
attributable to class A, class B and class M shares, respectively. The
Trustees have approved payment by the fund at the annual rates of 0.20%,
0.85% and 0.50% of the average net assets attributable to class A, class
B and class M shares, respectively.

For the year ended May 31, 2003, Putnam Retail Management, acting as
underwriter, received net commissions of $55,772 and $1,396 from the sale
of class A and class M shares, respectively, and received $213,017 in
contingent deferred sales charges from redemptions of class B shares. A
deferred sales charge of up to 1.00% is assessed on certain redemptions of
class A shares that were purchased without an initial sales charge as part
of an investment of $1 million or more. For the year ended May 31, 2003,
Putnam Retail Management, acting as underwriter, received $6,113 on class
A redemptions.


Note 3
Purchases and sales of securities

During the year ended May 31, 2003, cost of purchases and proceeds from
sales of investment securities other than short-term investments
aggregated $130,904,646 and $135,417,563, respectively. There were no
purchases and sales of U.S. government obligations.
