Dear Fellow Shareholder:

Looking back on an eventful year, we consider it important to take note
of the increasingly positive trends that have become apparent in the
U.S. economy and financial markets. The stimulus provided by fiscal and
monetary policies has drawn the economy out of the slump of early 2003
and rising profits prompted a broad rally for stocks. The bond market
steadied while offering pockets of opportunity. We see indications that
these trends can continue into 2004 and know that Putnam management
teams will seek to position the funds to benefit from them.

During the six months ended November 30, 2003, Putnam Ohio Tax Exempt
Income Fund outperformed its Lipper category average at net asset value
largely because of strong performance by several key holdings and
successful duration management. However, the fund underperformed its
benchmark essentially because of differences in portfolio composition.
You will find the details on the facing page. The fund's management team
also offers a full discussion of its duration management strategy and
the performance of a number of the fund's holdings. They conclude by
offering their view of prospects for the fiscal year's second half.

Respectfully yours,

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

   Income Fund's class A shares returned 0.05% at net asset value (NAV) and
   -4.73% at public offering price (POP).

 * Differences in portfolio composition caused the fund to underperform

 * See the Performance Summary on page 7 for complete fund performance,
   comparative performance, and Lipper data.

Performance commentary

In what proved a challenging six-month period for the overall municipal
bond market, the Ohio municipal market offered limited opportunities to
investors. This helps explain your fund's underperformance relative to
its benchmark index, which is nationally diversified. However, the
fund's investment mix and the adjustments we made to its portfolio
helped keep its investment results slightly ahead of the average for its
Lipper category over the first half of fiscal 2004. Relative to the
Lipper group, the fund benefited from a more defensive stance regarding
the direction of interest rates. In addition, a cross-market arbitrage
position contributed to returns. A third factor was the fund's
allocation to a variety of lower-quality, higher-yielding bonds.
Improving economic numbers this spring fostered an optimistic outlook,
and made income-oriented investors more willing to accept the risks
associated with these bonds. Furthermore, the increased demand helped
drive up prices.

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 unusually volatile between June 1 and November 30, 2003.
Concern about deflation led to falling yields and correspondingly higher
bond prices through mid June. After rising through August, yields
receded again in September on unfavorable housing and unemployment data.
October's positive economic surprises sent yields back up. Overall,
yields ended the semiannual period higher. The spread, or difference
between yields of 10-year municipal bonds and 10-year Treasuries,
widened, with municipals yielding close to their long-term average of
85% of comparable Treasury yields at the end of November after yielding
nearly 100% of Treasury yields earlier in the year.

As the economy improved, investor demand for higher-yielding municipals
increased. In particular, airline-related industrial development bonds
outperformed other municipal bonds. Tobacco settlement bonds
underperformed in the late spring following unfavorable rulings in some
of the industry's ongoing litigation matters. However, these bonds began
to outperform during the six-month period as prospects for the industry
became more favorable.

Strategy overview

We shortened duration (a measure of a fund's sensitivity to changes in
interest rates) in May and June because interest rates were at
historically low levels and were more likely, in our opinion, to rise
than to fall. This defensive strategy helped protect portfolio assets
when rates rose sharply between mid June and the end of July. We resumed
a neutral duration in August and September, as we believed rates were
unlikely to rise further. In September, rates fell again, so we
shortened duration somewhat. This was beneficial when rates rose in
October. At the end of the period, the portfolio's duration remained
slightly defensive.

In late July and early August, we closed out the cross-market arbitrage
position we had established in an earlier period. You may recall that we
sought to take advantage of a market anomaly in which municipal bond
yields, which are generally tax exempt, were nearly as high as
comparable taxable Treasury yields. We bought intermediate-term
municipal bonds and sold 10-year Treasury futures contracts,
anticipating that the muni/Treasury yield ratio would revert to its
long-term average and create an opportunity for gain. In fact, the yield
ratio did fall, and a loss in value of the muni bonds was more than
offset by a gain in the value of the Treasury futures position. We sold
the muni bonds and bought back the Treasury futures contracts, thereby
ending the trade and locking in a profit for the fund.

We took the opportunity afforded by strong demand for higher-yielding
municipal bonds to take profits where appropriate. We continued to
diversify the portfolio by adding selectively to the fund's
lower-quality holdings. Overall, however, we were not particularly
active buyers or sellers. We tended to hold on to what we had already
owned through the period. That approach resulted in part from the fact
that there were limited opportunities for initiating new investments in
the Ohio market.

How fund holdings affected performance

While your fund's portfolio is primarily investment grade, exposure to a
variety of high-yield municipal bonds boosted performance over the
period. The portfolio's top performer was an airline-related industrial
development bond (IDB). This type of municipal bond is usually issued to
finance local expansion by various businesses, and is backed by the
credit of the company benefiting from the financing. As a result, IDB
prices are affected by investor perceptions of the health of the backing
company or of the industry group. Especially since the terrorist attacks
of September 11, 2001, airline-backed IDBs (generally issued to finance
airport facility expansion) have been severely affected by declining air
traffic, high fixed costs, and high-profile bankruptcies. As the prospects
for economic recovery improved, the airline companies strengthened and
concerns about bankruptcies diminished. This led to a sharp price
recovery for these bonds and we used this opportunity to trim the one
airline-related IDB owned by the fund, a bond issued for Continental
Airlines with a 5.7% coupon and a 2019 maturity date. Since this bond
had been in the portfolio for some time, the sale did not result in a
profit based on its acquisition cost, but the fund was able to sell on
strength rather than in distress. We believe the airline industry may
continue to recover with the economy, but we also see potentially
greater opportunities in other market areas.

Other bonds that performed well were tobacco settlement bonds, primarily
due to a series of more positive legal judgments. These investments
included a bond issued by Children's Trust Fund of Puerto Rico, which
has a 5.375% coupon and matures in 2033, and one issued by the Virgin
Islands Tobacco Settlement Financing Corporation, with a 5% coupon and
which matures in 2021. Until recently, our view on the sector had been
less favorable because of the multibillion-dollar litigation pending
against the tobacco companies. This litigation, if successful, could
have affected the ability of tobacco companies to meet their settlement
payment obligations to the states and in turn, have a negative effect on
tobacco settlement bonds, which are secured by this promised income
stream. During the reporting period, the litigation environment shifted
in favor of tobacco companies, and in several cases, higher courts
reversed severe lower court judgments and outlined higher hurdles and
stricter rules for litigants against tobacco companies. This change
prompted our reversion to a more positive stance on the sector.

Relative detractors from the fund's performance during the period came
from higher-grade, longer-maturity bonds. There were no particular bonds
that stood out as particularly poor performers; rather, the fund's
holdings in these types of bonds simply did not perform as well as other
sectors of the market. These bonds suffered from weaker demand, as
investors became more attracted to higher-yielding, lower-quality
issues. In addition, the longer duration of these bonds made them
particularly susceptible to price declines amid an environment of
generally rising interest rates.

We were able to initiate new positions in some education bonds during
the period. We invested in four different bonds issued by the Ohio State
Higher Education Facilities Commission for John Carroll University,
which mature in 2007, 2008, 2017, and 2018. John Carroll is a Jesuit
institution located near Cleveland. The bond proceeds were used to
refund some previously issued bonds and to help build a new stadium on
the campus. The school has seen an increase in enrollment over the past
two years and has generated positive operating income since 2000. We
also invested in bonds issued by the Ohio State Higher Education
Facilities Commission for Oberlin College. One bond matures in 2024 and
carries a coupon rate of 5.125%. The other matures in 2033 and offers a
5% coupon. We were attracted to these securities because Oberlin has a
strong endowment as well as consistent enrollment statistics and
financial results. The bond proceeds were used to refund some
outstanding bonds and to build a 400-bed dormitory.

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), Richard Wyke (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.

We anticipate continued volatility in the coming six months and believe
the Federal Reserve Board will hold the federal funds rate steady at 1%.
Our 12- to 18-month outlook is less certain. If economic policy
succeeds, we may experience a classic bear market for bonds that may
push yields higher. However, it is also possible that the economy may
not respond satisfactorily to fiscal and monetary policy, and the yield
on 10-year Treasuries could fall. Given this degree of uncertainty, we
have, at this time, positioned the fund's duration somewhat defensively,
and we believe rates may rise in the short term. Currently, we no longer
see much opportunity to capitalize on yield spreads between municipal
bonds and Treasuries, as the relationship between them is now near the
long-term average. We expect that the credit quality of general
obligation municipal bonds will remain under pressure, because tax
revenues cannot be expected to grow significantly until taxpayers begin
to report improved earnings. Although yield spreads between high- and
low-quality municipal bonds have narrowed somewhat, we believe they
could narrow further. As a result, we may see more opportunity for
potential gain in this area. In keeping with the fund's objective, we
will continue to monitor market conditions as we pursue a high level of
tax-free income and manage the fund's risk exposures.

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 summary

This section provides information about your fund's performance during
the first half of its fiscal year, which ended November 30, 2003. In

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.

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).

A note about duplicate mailings

In response to investors' requests, the SEC has modified mailing
regulations for proxy statements, semiannual and annual reports, and
prospectuses. Putnam is now able to send a single copy of these
materials to customers who share the same address. This change will
automatically apply to all shareholders except those who notify us. If
you would prefer to receive your own copy, please call Putnam at
1-800-225-1581.

Putnam is committed to managing our mutual funds in the best interests
of our shareholders. Our proxy voting guidelines and policies are
available on the Putnam Individual Investor Web site,
www.putnaminvestments.com, by calling Putnam's Shareholder Services at
1-800-225-1581, or on the SEC's Web site, www.sec.gov.


A guide to the financial statements

These sections of the report, as well as the accompanying Notes,
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 period.

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.

  (a) Percentages indicated are based on net assets of $209,595,063.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to
      be the most recent ratings available at November 30, 2003 for the
      securities listed. Ratings are generally ascribed to securities at the
      time of issuance. While the agencies may from time to time revise such
      ratings, they undertake no obligation to do so, and the ratings do not
      necessarily represent what the agencies would ascribe to these
      securities at November 30, 2003. Securities rated by Putnam are
      indicated by "/P" and are not publicly rated.

      The rates shown on VRDN, mandatory put bonds and FRB are the current
      interest rates shown at November 30, 2003.

      The rates shown on IFB, which are securities paying interest rates that
      vary inversely to changes in the market interest rates, are the current
      interest rates at November 30, 2003.

      The fund had the following industry group concentrations greater than
      10% at November 30, 2003
      (as a percentage of net assets):

         Heath care              18.2%
         Education               11.9

      The fund had the following insurance concentrations greater than 10% at

Notes to financial statements
November 30, 2003 (Unaudited)

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 4.75%. 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 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) 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 maintain an asset coverage
ratio of at least 300% and borrowings must 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, 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 $4,308,173
available to the extent allowed by tax law to offset future net capital
gain, if any. The amount of the carryover and the expiration dates are:

Loss Carryover  Expiration
- --------------------------------
   $3,947,928   May 31, 2009
      360,245   May 31, 2010

The aggregate identified cost on a tax basis is $194,547,359, resulting
in gross unrealized appreciation and depreciation of $13,330,593 and
$482,661, respectively, or net unrealized appreciation of $12,847,932.

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. 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.


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 six months ended November 30,
2003, the fund's expenses were reduced by $17,639 under these
arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $641 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 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 six months ended November 30, 2003, Putnam Retail Management,
acting as underwriter, received net commissions of $10,936 and $54 from
the sale of class A and class M shares, respectively, and received
$52,252 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 six
months ended November 30, 2003, Putnam Retail Management, acting as
underwriter, received $567 on class A redemptions.

Note 3
Purchases and sales of securities

During the six months ended November 30, 2003, cost of purchases and
proceeds from sales of investment securities other than short-term
investments aggregated $18,025,343 and $38,289,797, respectively. There
were no purchases and sales of U.S. government obligations.

Note 4

On November 13, 2003, Putnam Management agreed to entry of an order by
the Securities and Exchange Commission (SEC) in partial resolution of
administrative and cease-and-desist proceedings initiated by the SEC on
October 28, 2003 in connection with alleged excessive short-term trading
by at least six Putnam Management investment professionals. The SEC's
findings reflect that four of those employees engaged in such trading in
funds over which they had investment decision-making responsibility and
had access to non-public information regarding, among other things,
current portfolio holdings, and valuations. The six individuals are no
longer employed by Putnam Management. Under the order, Putnam Management
will make restitution for losses attributable to excessive short-term
trading by Putnam employees, institute new employee trading restrictions
and enhanced employee trading compliance, retain an independent
compliance consultant, and take other remedial actions. Putnam
Management neither admitted nor denied the order's findings, which
included findings that Putnam Management willfully violated provisions
of the federal securities laws. A civil monetary penalty and other
monetary relief, if any, will be determined at a later date. If a
hearing is necessary to determine the amounts of such penalty or other
relief, Putnam Management will be precluded from arguing that it did not
violate the federal securities laws in the manner described in the SEC
order, the findings set forth in the SEC order will be accepted as true
by the hearing officer and additional evidence may be presented. Putnam
Management, and not the investors in any Putnam fund, will bear all
costs, including restitution, civil penalties and associated legal fees.
Administrative proceedings instituted by the Commonwealth of
Massachusetts on October 28, 2003 against Putnam Management in
connection with alleged market timing activities by Putnam employees and
by participants in some Putnam-administered 401(k) plans are pending.
Putnam Management has committed to make complete restitution for any
losses suffered by Putnam shareholders as a result of any improper
market-timing activities by Putnam employees or within
Putnam-administered 401(k) plans.

The SEC's and Commonwealth'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.

Review of these matters by counsel for Putnam Management and by separate
independent counsel for the Putnam funds and their independent Trustees
is continuing. In addition, Marsh & McLennan Companies, Inc., Putnam
Management's parent company, has engaged counsel to conduct a separate
review of Putnam Management's policies and controls related to
short-term trading. The fund may experience increased redemptions as a
result of these matters, which could result in increased transaction
costs and operating expenses.
