Dear Fellow Shareholder:

Over the past several months, Putnam has introduced a number of
voluntary reforms. We would like to call your attention to two of them
that are now being included in these reports to provide shareholders
with more useful information about their investments. Following the
performance tables in the Performance Summary, you will find new expense
and risk comparison information for your fund. The expense comparison
information enables you to estimate the amount you have actually paid
for ongoing expenses such as management fees and distribution (or 12b-1)
fees and to compare these expenses with the average expenses of funds in
your fund's Lipper peer group. The risk comparison shows your fund's
risk relative to similar funds as tracked by Morningstar, an independent
fund-rating company. We believe the expense and risk comparisons are
valuable tools for you and your financial advisor to use when making
decisions about your financial program. These enhancements to our
reports are just part of the additional disclosure we are committed to
providing to shareholders.

Putnam Ohio Tax Exempt Income Fund's fiscal year, which ended May 31,
2004, was a volatile period. Thanks to several key holdings and
defensive management strategies, your fund was able to outperform its
Lipper peer group at net asset value. However, the fund underperformed
its nationally diversified benchmark, essentially because of differences
in portfolio composition. Details are included in the discussion that
begins on the facing page.

As always, we appreciate your support of Putnam Investments.

Respectfully yours,

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

Report from Fund Management

Fund highlights

 * Putnam Ohio Tax Exempt Income Fund's total return for the fiscal year
   ended May 31, 2004, was -0.49% for class A shares at net asset value
   (NAV) and -5.26% at public offering price (POP).

 * The fund lagged the Lehman Municipal Bond Index, which returned -0.03%
   for the same period. In part, the difference reflects the portfolio
   composition of this single-state fund versus the nationally diversified
   index.

 * Strong performance from several lower-rated holdings helped the fund
   at NAV to outperform the average for its Lipper category, Ohio Municipal
   Debt Funds, which was -1.09% for the 12-month period.

 * See the Performance Summary on page 7 for complete information on the
   fund's results, performance comparisons, and Lipper data.

Performance commentary

Although interest rates rose and fell at different times during the past
12 months, rates ended the period higher than they were at the outset,
resulting in lower bond prices. The fund's underperformance relative to
the Lehman benchmark primarily reflects the fact that the index is
nationally diversified, while your fund concentrates on bonds issued in
a single state. This concentration is an advantage for tax-sensitive
Ohio residents, but it limits the fund's investment opportunities.

The fund's lower-rated holdings -- particularly its position in an
airline-related industrial development bond (IDB) issued for Continental
Airlines -- proved beneficial, as improving economic numbers and
persistently low interest rates prompted more investors to reach for
higher yields, boosting demand and consequently prices for these bonds.
This exposure to higher-yielding bonds, and the fund's relatively
defensive duration strategy during the period, helped the fund
outperform the average for its Lipper peer group, based on results at
NAV.

FUND PROFILE

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


Market overview

Municipal bond yields -- which move in the opposite direction of their
prices -- were volatile during the fiscal year ended May 31, 2004.
Concern about deflation led to falling yields through mid June of 2003.
This was followed by a period of rising yields through August. Then,
yields trended downward until they corrected sharply in late March and
April in response to much stronger economic data. At the end of the
period, yields on 10-year AAA-rated municipal bonds were slightly higher
than they had been at the beginning of the period. The ratio of
municipal bond yields to Treasury yields fell to about 80% in December,
which means the difference between the yields of 10-year municipal bonds
and 10-year Treasuries increased. The ratio edged up to about 85% by the
end of the fiscal period. Overall, the yield curve, which shows the
difference in yields over a range of bond maturities, flattened
somewhat, and credit spreads, which show the difference in yield between
higher- and lower-rated bonds, generally narrowed. The economy improved
on nearly all fronts, including job growth. The Federal Reserve Board
held the federal funds rate steady at 1%, but hinted at a potential rate
hike in the near future. Municipal bond issuance remained strong. In
May, California issued the first portion of its recently approved $15
billion bond issue to help alleviate the state's budget crisis. Although
ongoing tobacco litigation continued to make headlines, the municipal
bond market largely discounted the news. Airline-related IDBs turned in
mixed results as a period of strength was followed by weakening toward
period-end. In our opinion, the combination of higher fuel costs and
competition from low-cost carriers makes the outlook for major airlines
less favorable.

Strategy overview

In an increasingly strong economy, it appears likely that interest rates
will rise further. Consequently, we shortened the fund's duration (a
measure of a fund's sensitivity to changes in interest rates) relative
to that of its peer group during the period.

We took the opportunity afforded by strong demand for higher-yielding
municipal bonds to sell into strength where appropriate. We also
continued to diversify the portfolio by adding selectively to the fund's
lower-quality holdings. These below-investment-grade, higher-yielding
bonds are not a component of the fund's benchmark but we believe that
careful selection among them can continue to provide the fund with
attractive opportunities for income.

We carefully monitored developments in the tobacco industry,
particularly with regard to ongoing litigation and other factors
affecting demand for tobacco settlement bonds, which are secured by the
income stream from tobacco companies' settlement obligations to the
states. The municipal bond market has largely ignored recent unfavorable
headlines and the downgrading of some tobacco settlement bonds by
Moody's rating service. In our view, the backdrop for the tobacco
industry remains fundamentally positive, and the fund remains
overweighted in these bonds relative to the benchmark.

As certain airline-related IDBs continued to rebound during the period,
we took the opportunity to sell the fund's holdings into this strength.
As noted previously, our outlook for the major airlines is not favorable
at this time.

How fund holdings affected performance

When economic growth improves, the chances of a company or a
municipality defaulting generally decreases. This helps explain why
credit spreads -- the difference between higher- and lower-rated bonds
- -- generally narrowed over the course of the year, reflecting investors'
rising confidence in the economy and fiscal health of lower-rated
issuers. While your fund's portfolio is composed primarily of bonds
rated investment-grade or higher, its exposure to a variety of
high-yield municipal bonds boosted performance during the fiscal year.
We have been diversifying the fund's holdings in this sector to help
manage risk.

The fund's best results came from its holding in an airline-related
industrial development bond (IDB) backed by Continental Airlines,
although the issue gave up some of its strong gains in the final months
of the period. IDBs are municipal bonds issued to encourage local
expansion by various businesses. They are backed only by the credit of
the company benefiting from the financing, not by the issuing
municipality. As a result, investor perceptions about the backing
company's health, or that of its industry group as a whole, affect the
prices of these bonds. Early in the fiscal year, the airline industry
continued to feel the effects of declining air traffic, high fixed
costs, and high-profile bankruptcies. However, as geopolitical tensions
eased following what appeared to be the end of full-scale conflict in
Iraq, and as the global economy began to show signs of increased growth,
investors became more optimistic about the prospects for increased
travel and improving airline-industry fundamentals. This led to a sharp
rise in the price of airline-backed IDBs as many of these bonds
recovered from previously distressed levels. We took advantage of price
appreciation in this sector to selectively trim the fund's exposure to
the Continental Airlines bonds. Since they had been in the portfolio for
some time, the sale did not result in a profit based on the acquisition
cost, but the fund was able to sell on strength rather than in distress.

Bonds that performed particularly well for the fund during the fiscal
year included two hospital issues -- Tuscarawas County Hospital
Facilities bonds for Union Hospital and Franklin County Health Care
Facilities for Friendship Village of Dublin -- and one industrial
development bond, Ohio State Water Development Authority for BHP Steel.

Tobacco settlement bonds also generated strong results during the latter
half of the period as they recovered from investor concerns about
pending litigation -- some involving multibillion-dollar judgments --
against tobacco companies. Investors worried that these potential
liabilities would affect tobacco companies' ability to meet their
settlement payment obligations to the states. This would have a negative
impact on tobacco settlement bonds, which are secured by this promised
income stream.

During the period, however, the litigation environment shifted in favor
of tobacco companies as, in several cases, higher courts reversed lower
court judgments and outlined higher hurdles and stricter rules for
litigants against tobacco companies. This change prompted our reversion
to a more positive outlook on this sector. Although we reduced the
positions somewhat, the fund maintained its emphasis on tobacco
settlement bonds throughout the fiscal year, including bonds issued for
Children's Trust Fund of Puerto Rico and the Tobacco Settlement
Financing Corp. of the Virgin Islands.

There were no individual bonds that detracted from the fund's
performance during the period. Rather, the portfolio's higher-quality,
longer-term bonds were its weakest performers, as a stronger economy and
concern that interest rates may be about to rise attracted investors to
higher-yielding, lower-quality bonds and shorter-term issues.

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 David Hamlin (Portfolio Leader), Paul Drury
(Portfolio Member), Susan McCormack (Portfolio Member), James St. John
(Portfolio Member), and Kevin Cronin.


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.

Early in 2004, lingering unemployment had been an anomaly in an
otherwise robust economic recovery. However, in April, employment data
at last showed marked improvement in job creation. We believe the
underlying strength in the economy will foster higher interest rates in
the future. In keeping with our views, the fund's duration is now
relatively short in order to keep the portfolio defensively positioned.
We expect that the credit quality of general obligation municipal bonds
will improve gradually as the economy improves and tax revenues
increase. Although yield spreads between high- and low-quality municipal
bonds have narrowed somewhat, we believe they remain attractive and
could narrow further. As a result, we believe credit risk is worth
taking in moderate amounts, while we continue to seek diversification by
sector and issuer. We will closely monitor market conditions as we
pursue a high level of tax-free income and seek to manage the fund's
risk exposure.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. This fund
concentrates its investments in one state and involves more risk than a
fund that invests more broadly. Capital gains, if any, are taxable for
federal and, in most cases, state purposes. For some investors,
investment income may be subject to the federal alternative minimum tax.
Income from federally exempt funds may be subject to state and local
taxes. Tax-free funds may not be suitable for IRAs and other non-taxable
accounts.

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 (which
for class A shares does not reflect a reduction in sales charges that
went into effect on January 28, 2004; if this reduction had been in
place for all periods indicated, returns would have been higher). 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 limited expenses, without which returns would have been lower.

A 2% short-term trading fee will be applied to shares exchanged or sold
within 5 days of purchase.

   divided by NAV or POP at end of period.

 3 Assumes maximum 39.88% federal and state combined tax rate for 2004.
   Results for investors subject to lower tax rates would not be
   advantageous.

 4 For a portion of the period, this fund limited expenses, without which
   yields would have been lower. Based only on investment income,
   calculated using SEC guidelines.

Understanding your
fund's expenses

As a mutual fund investor, you pay ongoing expenses, such as management
fees, distribution fees (12b-1 fees), and other expenses. In the most
recent six-month period, your fund limited these expenses; had it not
done so, expenses may have been higher. Using the information below, you
can estimate how these expenses affect your investment and compare them
with the expenses of other funds. You may also pay one-time transaction
expenses, including sales charges (loads) and redemption fees, which are
not shown in this section and would have resulted in higher
total expenses. For more information, see your fund's prospectus or talk
to your financial advisor.

Review your fund's expenses

The table below shows the expenses you would have paid on a $1,000
investment in Putnam Ohio Tax Exempt Income Fund from December 1, 2003,
to May 31, 2004. It also shows how much a $1,000 investment would be
worth at the close of the period, assuming actual returns and expenses.

Ending value (after expenses)     $995       $991       $992
- -------------------------------------------------------------------------

* Expenses for each share class are calculated using the fund's
  annualized expense ratio for each class, which represents the ongoing
  expenses as a percentage of net assets for the six months ended 5/31/04.
  The expense ratio may differ for each share class (see the table at the
  bottom of the next page). Expenses are calculated by multiplying the
  expense ratio by the average account value for the period; then
  multiplying the result by the number of days in the period; and then
  dividing that result by the number of days in the year.

Comparing your fund's expenses with those of other funds

Using the SEC's method to compare expenses

The Securities and Exchange Commission (SEC) has established guidelines
to help investors assess fund expenses. Per these guidelines, the table
below shows your fund's expenses based on a $1,000 investment, assuming
a hypothetical 5% annualized return. You can use this information to
compare the ongoing expenses (but not transaction expenses or total
costs) of investing in the fund with those of other funds. All mutual
fund shareholder reports will provide this information to help you make
this comparison. Please note that you cannot use this information to
estimate your actual ending account balance and expenses paid during the
period.

 * Expenses for each share class are calculated using the fund's
   annualized expense ratio for each class, which represents the ongoing
   expenses as a percentage of net assets for the six months ended 5/31/04.
   The expense ratio may differ for each share class (see the table at the
   bottom of this page). Expenses are calculated by multiplying the expense
   ratio by the average account value for the period; then multiplying the
   result by the number of days in the period; and then dividing that
   result by the number of days in the year.

Using industry averages to compare expenses

You can also compare your fund's expenses with industry averages, as
determined by Lipper, an independent fund-rating agency that ranks funds
relative to others that Lipper considers to have similar investment
styles or objectives. The expense ratio for each share class shown below
indicates how much of your fund's net assets have been used to pay
ongoing expenses during the period.

 + For the fund's most recent fiscal half year; may differ from
   expense ratios based on one-year data in the financial highlights.

++ For class A shares, expenses shown represent the average of the
   expenses of front-end load funds viewed by Lipper as having the same
   investment classification or objective as the fund, calculated in
   accordance with Lipper's standard reporting methodology for comparing
   expenses within a given universe. All Lipper data is for the most recent
   fiscal periods available as of 3/31/04.  For class B and M shares,
   Putnam has adjusted the Lipper total expense average to reflect higher
   12b-1 fees incurred by these classes of shares. The peer group may
   include funds that are significantly larger or smaller than the fund,
   which may limit the comparability of the fund's expenses to the Lipper
   average.


Risk comparison

As part of new initiatives to enhance disclosure, we are including a
risk comparison to help you understand how your fund compares with other
funds. The comparison utilizes a risk measure developed by Morningstar,
an independent fund-rating agency. This risk measure is referred to as
the fund's Overall Morningstar Risk.

[GRAPHIC OMITTED: chart MORNINGSTAR [REGISTRATION MARK] RISK]

MORNINGSTAR [REGISTRATION MARK] RISK

Fund's Overall
Morningstar Risk    0.19

Municipal bond
fund average        0.22

0%   Increasing Risk   100%

Your fund's Overall Morningstar Risk is shown alongside that of the
average fund in its broad asset class, as determined by Morningstar. The
risk bar broadens the comparison by translating the fund's Overall
Morningstar Risk into a percentile, which is based on the fund's ranking
among all funds rated by Morningstar as of 6/30/04. A higher Overall
Morningstar Risk generally indicates that a fund's monthly returns have
varied more widely.

Morningstar determines a fund's Overall Morningstar Risk by assessing
variations in the fund's monthly returns -- with an emphasis on downside
variations -- over 3-, 5-, and 10-year periods, if available. Those
measures are weighted and averaged to produce the fund's Overall
Morningstar Risk. The information shown is provided for the fund's class
A shares only; information for other classes may vary. Overall
Morningstar Risk is based on historical data and does not indicate
future results. Morningstar does not purport to measure the risk
associated with a current investment in a fund, either on an absolute
basis or on a relative basis. Low Overall Morningstar Risk does not mean
that you cannot lose money on an investment in a fund. Copyright 2004

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 (since reduced to 4.50%) 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).

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

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

A guide to the financial statements

These sections of the report, as well as the accompanying Notes,
preceded by the Report of Independent Registered Public Accounting Firm,
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 Registered Public Accounting Firm

To the Trustees and Shareholders of
Putnam Ohio 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 Ohio Tax Exempt Income Fund (the "fund") at
May 31, 2004, 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 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, 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, 2004, by correspondence
with the custodian, provide a reasonable basis for our opinion.

Notes to financial statements
May 31, 2004

Note 1
Significant accounting policies

Putnam Ohio 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 Ohio 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 Ohio tax-exempt securities with
intermediate- to long-term maturities. The fund may be affected by
economic and political developments in the state of Ohio.

The fund offers class A, class B and class M shares. Class A shares are
sold with a maximum front-end sales charge of 4.50%. Prior to January
28, 2004, the maximum front-end sales charge for class A shares was
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 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.

Effective April 19, 2004 (May 3, 2004 for defined contribution plans
administered by Putnam) a 2.00% redemption fee may apply to any shares
that are redeemed (either by selling or exchanging into another fund)
within 5 days of purchase.

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 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 at fair
value 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. Other investments, including 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. Risks may exceed amounts recognized on the statement
of assets and liabilities. 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, if any,
are listed after the fund's portfolio.

D) Line of credit During the period, the fund was entered into a
committed line of credit with certain banks. The line of credit
agreement included restrictions that the fund would maintain an asset
coverage ratio of at least 300% and that borrowings would not exceed
prospectus limitations. For the period ended August 6, 2003 the fund had
no borrowings against the line of credit. Effective August 6, 2003, the
fund no longer participated in a committed line of credit.

E) 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 (the "Code"), 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, 2004, the fund had a capital loss carryover of $2,427,028
available to the extent allowed by the Code to offset future net capital
gain, if any. The amount of the carryover and the expiration dates are:

Loss Carryover    Expiration
- ------------------------------
   $2,066,783     May 31, 2009
      360,245     May 31, 2010

F) 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 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

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.

Effective January 28, 2004, Putnam Management has agreed to limit its
compensation (and, to the extent necessary, bear other expenses) through
December 31, 2004, to the extent that the fund's net expenses as a
percentage of average net assets exceed the average expense ratio for
the fund's Lipper peer group of front-end load funds.

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. Putnam
Investor Services, a division of PFTC, provides investor servicing agent
functions to the fund. During the year ended May 31, 2004, the fund paid
PFTC $250,558 for these services.

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, 2004, the
fund's expenses were reduced by $30,046 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $651, as a quarterly retainer, 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 Trustee compensation and expenses in the
statement of operations. Accrued pension liability is included in
Payable for Trustee compensation and expenses 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 in distributing shares of the fund. The Plans
provide for payments by the fund to Putnam Retail Management at annual
rates of up to 0.35%, 1.00%, 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, 2004, Putnam Retail Management, acting as
underwriter, received net commissions of $13,011 and $116 from the sale
of class A and class M shares, respectively and $65,961 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, 2004, Putnam Retail Management, acting as
underwriter, received $5,670 on class A redemptions.

Note 3
Purchases and sales of securities

During the year ended May 31, 2004, cost of purchases and proceeds from

Note 5
Regulatory matters and litigation

On April 8, 2004, Putnam Management entered into agreements with the
Securities and Exchange Commission and the Massachusetts Securities
Division representing a final settlement of all charges brought against
Putnam Management by those agencies on October 28, 2003 in connection
with excessive short-term trading by Putnam employees and, in the case
of the charges brought by the Massachusetts Securities Division, by
participants in some Putnam-administered 401(k) plans. The settlement
with the SEC requires Putnam Management to pay $5 million in
disgorgement plus a civil monetary penalty of $50 million, and the
settlement with the Massachusetts Securities Division requires Putnam
Management to pay $5 million in restitution and an administrative fine
of $50 million. The settlements also leave intact the process
established under an earlier partial settlement with the SEC under which
Putnam Management agreed to pay the amount of restitution determined by
an independent consultant, which may exceed the disgorgement and
restitution amounts specified above, pursuant to a plan to be developed
by the independent consultant.

Putnam Management, and not the investors in any Putnam fund, will bear
all costs, including restitution, civil penalties and associated legal
fees stemming from both of these proceedings. The SEC's and
Massachusetts Securities Division's allegations and related matters also
serve as the general basis for numerous lawsuits, including purported
class action lawsuits filed against Putnam Management and certain
related parties, including certain Putnam funds. Putnam Management has
agreed to bear any costs incurred by Putnam funds in connection with
these lawsuits. Based on currently available information, Putnam
Management believes that the likelihood that the pending private
lawsuits and purported class action lawsuits will have a material
adverse financial impact on the fund is remote, and the pending actions
are not likely to materially affect its ability to provide investment
management services to its clients, including the Putnam funds.

For the period ended May 31, 2004, Putnam Management has assumed $3,591
of legal, shareholder servicing and communication, audit, and Trustee
fees incurred by the Fund in connection with these matters.

Review of these matters by counsel for Putnam Management and by separate
independent counsel for the Putnam funds and their independent Trustees
is continuing. The fund may experience increased redemptions as a result
of these matters, which could result in increased transaction costs and
operating expenses.

Putnam puts your interests first

In January, Putnam announced a number of voluntary initiatives designed
to reduce fund expenses, provide investors with more useful information,
and help safeguard the interests of all Putnam investors. For details,
visit www.putnaminvestments.com.

Cost-cutting initiatives

Reduced sales charges

Effective immediately, the maximum sales charge for class A shares has
been reduced to 5.25% for equity funds (formerly 5.75%) and 4.50% for
most income funds  (formerly 4.75%).*

Lower class B purchase limit

To help ensure that investors are in the most cost-effective share
class, the maximum amount that can be invested in class B shares has
been reduced to $100,000. (Larger trades or accumulated amounts will be
directed  to class A shares.)

Ongoing expenses will be limited

During calendar 2004, total ongoing expenses, including management fees
for all funds, will be maintained at or below the average of each fund's
industry peers in its Lipper load-fund universe. For more information,
please see the Statement of Additional information.

Additional measures are being taken to reduce expenses for shareholders
in the six global and international funds that  had short-term trading
issues.

Improved disclosure

Putnam fund prospectuses and shareholder reports are being revised to
disclose additional information that will help shareholders compare
funds and weigh their costs and risks along with their potential
benefits. Shareholders will find easy-to-understand information about
fund expense ratios, portfolio manager compensation, risk comparisons,
brokerage commissions, and employee and trustee ownership of Putnam
funds. Disclosure of breakpoint discounts  is also being enhanced to
alert investors to potential cost savings.

Protecting investors' interests

New short-term trading fee introduced

To discourage short-term trading, which can interfere with a fund's
long-term strategy, a 2% short-term trading fee will be imposed on any
Putnam fund shares redeemed or exchanged within five calendar days  of
purchase.

* The maximum sales charge for class A shares of Putnam U.S. Intermediate
  Government Income Fund remains 3.25%.

Item 2. Code of Ethics:
- -----------------------
All officers of the Fund, including its principal executive, financial and
accounting officers, are employees of Putnam Investment Management, LLC,
the Fund's investment manager.  As such they are subject to a comprehensive
Code of Ethics adopted and administered by Putnam Investments which is
designed to protect the interests of the firm and its clients.  The Fund
has adopted a Code of Ethics which incorporates the Code of Ethics of
Putnam Investments with respect to all of its officers and Trustees who are
employees of Putnam Investment Management, LLC.  For this reason, the Fund
has not adopted a separate code of ethics governing its principal
executive, financial and accounting officers.

Item 3. Audit Committee Financial Expert:
- -----------------------------------------
The Funds' Audit and Pricing Committee is comprised solely of Trustees
who are "independent" (as such term has been defined by the Securities
and Exchange Commission ("SEC") in regulations implementing Section 407
of the Sarbanes-Oxley Act (the "Regulations")).  The Trustees believe
that each of the members of the Audit and Pricing Committee also possess
a combination of knowledge and experience with respect to financial
accounting matters, as well as other attributes, that qualify them for
service on the Committee.  In addition, the Trustees have determined
that all members of the Funds' Audit and Pricing Committee meet the
financial literacy requirements of the New York Stock Exchange's rules
and that Mr. Patterson and Mr. Stephens qualify as "audit committee
financial experts" (as such term has been defined by the Regulations)
based on their review of their pertinent experience and education.
Certain other Trustees, although not on the Audit and Pricing Committee,
would also qualify as "audit committee financial experts."  The SEC has
stated that the designation or identification of a person as an audit
committee financial expert pursuant to this Item 3 of Form N-CSR does
not impose on such person any duties, obligations or liability that are
greater than the duties, obligations and liability imposed on such
person as a member of the Audit and Pricing Committee and the Board of
Trustees in the absence of such designation or identification.

Item 4. Principal Accountant Fees and Services:
- -----------------------------------------------
The following table presents fees billed in each of the last two
fiscal years for services rendered to the fund by the fund's
independent auditors:

                    Audit       Audit-Related   Tax       All Other
Fiscal year ended   Fees        Fees            Fees      Fees
- -----------------   ----------  -------------   -------   ---------
May 31, 2004        $36,315 *   $--             $5,933    $39
May 31, 2003        $31,562     $--             $4,946    $--

*Includes fees of $78 billed by the fund's independent auditor to
the fund for audit procedures necessitated by regulatory and
litigation matters.  These fees were reimbursed to the fund by
Putnam.

For the fiscal years ended  May 31, 2004 and May 31, 2003, the
fund's independent auditors billed aggregate non-audit fees in the
amounts of $ 136,462  and $59,464 , respectively, to the fund,
Putnam Management and any entity controlling, controlled by or under
common control with Putnam Management that provides ongoing services
to the fund.

Audit Fees represents fees billed for the fund's last two fiscal
years.

Audit-Related Fees represents fees billed in the fund's last two
fiscal years for services traditionally performed by the fund's
auditor, including accounting consultation for proposed transactions
or concerning financial accounting and reporting standards and other
audit or attest services not required by statute or regulation.

Tax Fees represent fees billed in the fund's last two fiscal years
for tax compliance, tax planning and tax advice services.  Tax
planning and tax advice services include assistance with tax audits,
employee benefit plans and requests for rulings or technical advice
from taxing authorities.

All Other Fees represent fees billed for services relating to
fund expense processing.

Pre-Approval Policies of the Audit and Pricing Committee.  The Audit
and Pricing Committee of the Putnam funds has determined that, as a
matter of policy, all work performed for the funds by the funds'
independent auditors will be pre-approved by the Committee and will
generally not be subject to pre-approval procedures.

Under certain circumstances, the Audit and Pricing Committee
believes that it may be appropriate for Putnam Investment
Management, LLC ("Putnam Management") and certain of its affiliates
to engage the services of the funds' independent auditors, but only
after prior approval by the Committee.  Such requests are required
to be submitted in writing to the Committee and explain, among other
things, the nature of the proposed engagement, the estimated fees,
and why this work must be performed by that particular audit firm.
The Committee will review the proposed engagement at its next
meeting.

Since May 6, 2003, all work performed by the independent auditors
for the funds, Putnam Management and any entity controlling,
controlled by or under common control with Putnam Management that
provides ongoing services to the fund was pre-approved by the
Committee or a member of the Committee pursuant to the pre-approval
policies discussed above.  Prior to that date, the Committee had a
general policy to pre-approve the independent auditor's engagements
for non-audit services with the funds, Putnam Management and any
entity controlling, controlled by or under common control with
Putnam Management that provides ongoing services to the fund.

The following table presents fees billed by the fund's principal
auditor for services required to be approved pursuant to paragraph
(c)(7)(ii) of Rule 2-01 of Regulation S-X.

                    Audit-Related   Tax   All Other   Total Non-
Fiscal year ended   Fees            Fees  Fees        Audit Fees

Items 5-6. [Reserved]
- ---------------------

Item 7. Disclosure of Proxy Voting Policies and Procedures For Closed End
- -------------------------------------------------------------------------
        Management Investment Companies: Not applicable
        --------------------------------

Item 8. [Reserved]
- ------------------

Item 9. Submission of Matters to a Vote of Security Holders:
- ------------------------------------------------------------
        Not applicable

Item 10. Controls and Procedures:
- --------------------------------

(a) The registrant's principal executive officer and principal financial
officer have concluded, based on their evaluation of the
effectiveness of the design and operation of the registrant's
disclosure controls and procedures as of a date within 90 days of
the filing date of this report on Form N-CSR, that the design and
operation of such procedures are generally effective to provide
reasonable assurance that information required to be disclosed by
the investment company in the reports that it files or submits under
the Securities Exchange Act of 1934 is recorded, processed,
summarized and reported within the time periods specified in the
Commission's rules and forms.

Although such officers reached the conclusion expressed in the
preceding paragraph, they are aware of matters that raise concerns
with respect to controls, each of which arose in connection with the
administration of 401(k) plans by Putnam Fiduciary Trust Company.
The first matter, which occurred in early 2001, involved the willful
circumvention of controls by certain Putnam employees in connection
with the correction of operational errors with respect to a 401(k)
client's investment in certain Putnam Funds, which led to losses in
five Putnam Funds (not including the registrant). Such officers
became aware of this matter in February 2004. The second matter,
which occurred in 2002, involved the willful circumvention by
certain Putnam employees of policies and procedures in connection
with the payment of Putnam corporate expenses. Such officers did
not learn that this matter involved a Putnam Fund until January
2004. Putnam has made restitution to the affected Funds,
implemented a number of personnel changes, including senior
personnel, begun to implement changes in procedures to address these
items and informed the SEC, the Funds' Trustees and independent
auditors. An internal investigation and review of procedures and
controls are currently ongoing.

In reaching the conclusion expressed herein, the registrant's
principal executive officer and principal financial officer
considered a number of factors, including the nature of the matters
described above, when the matters occurred, the individuals
involved, personnel changes that have occurred since these matters
occurred, the results to date of the current ongoing investigation
and the overall quality of controls at Putnam at this time.

(b) Changes in internal control over financial reporting:
Not applicable

Item 11. Exhibits:
- ------------------

(a)  The Code of Ethics of The Putnam Funds, which incorporates the
Code of Ethics of Putnam Investments, is filed herewith.

(b) A separate certification for each principal executive officer and
principal financial officer of the registrant as required by Rule 30a-2
under the Investment Company Act of 1940, as amended, and the officer
certifications as required by Section 906 of the Sarbanes-Oxley Act
of 2002 are filed herewith.
