Dear Fellow Shareholder:

We are pleased to report positive performance for Putnam Global Natural
Resources Fund for the 12 months ended August 31, 2003. Because of the
specialized nature of the fund's portfolio, however, its results lagged
both that of its benchmark index and its Lipper category average. You
will find the details on the facing page.

The results for the full fiscal year reflect a shift for the better in
the mood of global equity investors, in contrast to the prevailing mood
at the period's midpoint, when a cloud of political and economic
uncertainties hung persistently over the markets. Some of these
uncertainties are becoming clarified, if not resolved, and the economies
of many countries and regions are exhibiting signs of increasing vigor.
As health returns to the global economy, the need for natural resources
should increase, brightening the prospects for the companies in which
your fund invests.

As the fund begins a new fiscal year that we hope will bring renewed
strength to the global equity markets, what we told you at the midpoint
of the fiscal year bears repeating. We deeply appreciate your continued
confidence in Putnam and we firmly believe that over the long haul your
patience will be rewarded.

Respectfully yours,

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

John A. Hill                  George Putnam, III
Chairman of the Trustees      President of the Funds

   performance, comparative performance, and Lipper data.


Performance commentary

Buoyed by a robust global equity market rally that began in March and
continued through period-end, Putnam Global Natural Resources Fund
turned in solid absolute performance for its fiscal year. The fund's
emphasis on energy-related companies caused it to modestly underperform
its more broadly diversified benchmark, the S&P 500 Index, as the market
rally that characterized the second half of the period favored other,
less defensive sectors.

FUND PROFILE

Putnam Global Natural Resources Fund seeks capital appreciation by
investing in stocks of companies in the energy and natural resources
industries. The fund targets companies in markets worldwide, in
industries such as oil and gas, chemicals, metals and mining, utilities,
and paper and forest products. The fund may be appropriate for investors
seeking long-term growth of capital.

The fund's portfolio composition often differs from its Lipper peer
group as we pursue a more diversified strategy in the global natural
resources sector. We work to balance fund holdings in the energy
industry with a significant exposure to basic materials industries such
as metals, chemicals, and paper. We believe these differences likely
account for the fund's underper formance versus its Lipper category for
the period.



Market overview

The fund's fiscal year results should be evaluated in the context of an
economic and market environment that was favorable for energy-related
holdings in the first half of the period but became less hospitable in
the latter half of the period.

The first half of the period was dominated by investor concerns about
the continued erosion of corporate earnings, geopolitical tension over
North Korea and Iraq, and the effectiveness of the U.S. Federal Reserve
Board's monetary policy. Stock prices exhibited unusual volatility
during this period, falling precipitously in the months leading up to
the conflict in Iraq. Energy-related holdings, which comprise about 80%
of the fund's portfolio, fared relatively well during this period as
risk-averse investors were drawn to the more defensive sectors of the
market. In addition, stock prices responded to rising energy prices, as
investors worried about the potential for war disrupting the flow of oil
and natural gas from the resource-rich Middle East.

Fueled by the end of major conflict in Iraq, continued favorable
monetary and fiscal policies, as well as signs of improving economic
growth and rising corporate earnings, stocks rallied robustly in the
second half of the period. However, the stock prices of companies in
energy-related industries didn't rise as much as those in the broader
market because investor focus shifted from defensive sectors to
higher-risk areas, such as technology. In addition, energy prices
dropped as geopolitical tensions eased.

Strategy overview

The fund maintained its emphasis on energy-related holdings during the
period, particularly oil and natural gas exploration and production
companies. We believe this segment of the natural resources sector is
poised to benefit from the secular trend of a decreasing supply of
natural gas in North America amid continued growing demand for this
efficient, clean energy source. Consistent with this theme, the
portfolio also emphasized energy services companies, which provide
pumping, process, pipeline, chemical, and completion services to oil and
natural gas exploration and production companies. Investing in companies
that can offer power producers an alternative to increasingly expensive
natural gas, such as coal, was another aspect of this strategy. The fund
also increased its exposure to large, integrated oil companies,
believing that these high-quality companies were available at attractive
valuations and offered solid long-term growth potential. However, this
strategy did not contribute to performance during the period, as
investors favored higher-risk, lower-quality companies amid the
liquidity-driven rally.

Within basic materials stocks, which comprise about 20% of the fund's
portfolio, we favored diversified metals at the expense of chemical
companies. We believe that diversified metal companies offer more
reliable cash flows than specialty miners. Chemical companies, which are
dependent on oil and gas products as feedstock, are challenged by rising
prices on these commodities. We also established a small position in the
building materials industry during the period.

How fund holdings affected performance

Fund holdings Apache Corporation -- one of the top ten holdings -- and
XTO Energy remained standout per form ers among the fund's large
exposure to oil and natural gas exploration and pro duction companies.
We added the Apache position during the period, as this well-run company
has a history of creating value through acquisitions and effective
manage ment. Canadian natural gas producers -- such as Nexen Inc.,
EnCana, and Canadian Natural Resources Limited, another top-ten holding
- -- were added at what we believe were attractive valuations relative to
their U.S. counterparts. We believe that these producers, which appear
poised to benefit from growing demand in the United States and Canada,
are an overlooked segment of the market.

The fund also initiated a position in U.K.-based natural gas explorer
and producer BG Group during the period. We were attracted by BG Group's
leadership in harvesting and delivering liquefied natural gas (LNG) to
the world's leading markets. LNG is created by cooling natural gas to
the point at which it becomes liquid, which is easier to transport.
Other factors that influenced the purchase were the strong performance
of BG's Atlantic LNG export facilities in Trinidad and Tobago as well as
new U.S. import capacity created by a recently signed long-term lease on
its Louisiana regasification facility -- one of only four such
facilities in the United States. Regasification plants convert LNG back
into a gas form for piping to consumers.

The fund's holdings will change over time.

We increased the fund's exposure to large, multinational, integrated oil
companies during the period -- such as France-based Total, SA and
Italy-based ENI SpA -- as many of these companies were available at what we
believed were attractive valuations. While the team believes these
high-quality companies offer solid long-term growth potential, two of the
fund's largest positions in this market segment, BP PLC and Royal Dutch
Petroleum Co., proved among the most significant detractors from relative
performance during the period. Two factors contributed to the relative
underperformance of integrated oil companies. First, in a global equity
market rally that was driven in large part by the liquidity provided by
historically low interest rates, investors favored higher-risk companies,
which benefit disproportionately under such conditions. Large integrated
oil companies, which are perceived as relatively stable, are viewed as
better defensive positions. In addition, as oil prices fell in the wake of
easing geopolitical tensions in Iraq, investors expected the profits of
these large oil companies to suffer the most.

In the energy services segment of the fund, we took advantage of strong
price appreciation to trim a large exposure to BJ Services Company, as
its stock's valuation level had risen above our fair value target price.
This holding was among the top contributors to relative results for the
period as were holdings of other service giants Halliburton Company and
Schlumberger Limited. Halliburton's stock price benefited from the
development of strategies expected to expedite the settlement of
asbestos and silica personal injury claims against two of the company's
subsidiaries.

Diversified metal companies remain our main emphasis in the basic
materials segment of the portfolio. Australian-based BHP Billiton, was a
strong contributor in this category. Gold miner, Newmont Mining
Corporation, and aluminum producer, Alcoa, were solid performers among
mining specialists. Elsewhere in basic materials, we added du Pont to
the fund's list of chemical companies, as its stockholders are expected
to benefit from a share repurchase program. We also initiated a position
in Ireland-based building materials giant CRH PLC, which we believe was
attractively valued and is poised to benefit from consolidation among
cement providers. 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 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.

The outlook for your fund is affected by factors specific to the natural
resources segment of the economy as well as by broader market factors.
As discussed, we expect scarcity and growing demand to lead to sustained
higher natural gas prices. We have positioned the fund to benefit from
this forecast. Likewise, the fund's  exposure to integrated oil
companies should benefit from high oil prices.

We believe broader market sentiment is also likely to shape the fund's
performance in the coming months. The global stock-market rally has been
driven by accumulating signs of an acceleration in global economic
growth. Yet it is still unclear whether that growth will be sufficiently
robust and prolonged to drive a sustained recovery in capital spending
(a key ingredient for long-term expansion). In our view, major
structural constraints on equity markets remain in place -- notably,
overcapacity and weak pricing power across many industries. Furthermore,
investors today may be too complacent about geopolitical risks, just as
they were too fearful about such risks last winter. We expect market
leadership to shift from its current liquidity-driven focus on the
stocks of smaller-cap companies and those with lower-quality financials
to stocks of larger-cap companies with higher-quality financials. We
believe this shift should benefit the fund's holdings in larger-cap
companies with high-quality financials, such as integrated oil.

Management will continue to target companies in the global natural
resources area whose business worth is believed to be more than their
current stock prices indicate. The companies we seek should also have
strong management teams, solid fundamentals, a favorable operating
environment, and a competitive advantage.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. International
investing involves certain risks, such as currency fluctuations,
economic instability, and political developments. The fund concentrates
its investments in one sector and involves more risk than a fund that
invests more broadly.

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 5.75% maximum sales charge for class A
shares and 3.50% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time
of the redemption of class B or C 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. The CDSC for class C shares is 1% for one
year after purchase.

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 C shares are not subject to an initial sales charge and are
subject to a contingent deferred sales charge only if the shares are
redeemed during the first year.

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 Independent Auditors' Report, 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.



Independent auditors' report

The Board of Trustees and Shareholders Putnam Global Natural Resources
Fund:

We have audited the accompanying statement of assets and liabilities of
Putnam Global Natural Resources Fund, including the fund's portfolio, as
of August 31, 2003, and the related statement of operations for the year
then ended, the statements of changes in net assets for each of the two
years in the period then ended and the financial highlights for each of
the four years in the period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management.
Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits. The financial
highlights for the year or period ended August 31, 1999 were audited by
other auditors whose report dated October 12, 1999 expressed an
unqualified opinion on those financial highlights.

We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that
we plan and perform our audit to obtain reasonable assurance about
whether the financial statements and financial highlights are free of
material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as
of August 31, 2003 by correspondence with the custodian and brokers or
by other appropriate auditing procedures where replies from brokers were
not received. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating
the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of Putnam Global Natural Resources Fund as of August
31, 2003, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then
ended, and the financial highlights for each of the four years in the
period then ended in conformity with accounting principles generally
accepted in the United States of America.

Note 1
Significant accounting policies

Putnam Global Natural Resources Fund (the "fund") is registered under
the Investment Com pany Act of 1940, as amended, as a diversified,
open-ended management investment company. The fund continues to seek
capital appreciation by investing primarily in the common stocks of
companies in the energy and natural resource industries.

The fund offers class A, class B, class C and class M shares. Class A
shares are sold with a maximum front-end sales charge of 5.75%. 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 C shares are subject to the same fees and
expenses as class B shares, except that class C shares have a one-year
1.00% contingent deferred sales charge and do not convert to class A
shares. Class M shares are sold with a maximum front end sales charge of
3.50% and pay an ongoing distribution fee that is higher than class A
shares but lower than class B and class C shares.

A redemption fee of 1.00% may apply to any shares held less than 90
days.

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 Investments for which market quotations are
readily available are valued at the last reported sales price on their
principal exchange, or official closing price for certain markets. If no
sales are reported -- as in the case of some securities traded
over-the-counter -- a security is valued at its last reported bid price.
For foreign investments, if trading or events occurring in other markets
after the close of the principal exchange in which the foreign
investments are traded are expected to materially affect the value of
the investments, then those investments are valued, taking into
consideration these events, at their fair value following procedures
approved by the Trustees. Securities quoted in foreign cur rencies are
translated into U.S. dollars at the current exchange rate. Short-term
investments having remaining maturities of 60 days or less are valued at
amortized cost, which approximates fair value. Other investments,
including restricted securities, are valued at fair value following pro
cedures approved by the Trustees. Such valuations and procedures are
reviewed periodically by the Trustees.

B) Joint trading account The fund may transfer uninvested cash balances,
including cash collateral received under security lending arrangements,
into a join trading account along with the cash of other registered
investment companies and certain other accounts managed by Putnam
Investment Management, LLC ("Putnam Management"), the fund's manager, an
indirect wholly-owned subsidiary of Putnam, LLC. These balances may be
invested in issuers of high-grade short-term investments having maturities
of up to 397 days for collateral received under security lending
arrangements and up to 90 days for other cash investments.

C) 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. Dividend income is recognized on the ex-dividend date except that
certain dividends from foreign securities are recognized as soon as the
fund is informed of the ex-dividend date. Non-cash dividends, if any,
are recorded at the fair market value of the securities received.

D) Foreign currency translation The accounting records of the fund are
maintained in U.S. dollars. The market value of foreign securities,
currency holdings, and other assets and liabilities are recorded in the
books and records of the fund after translation to U.S. dollars based on
the exchange rates on that day. The cost of each security is determined
using historical exchange rates. Income and withholding taxes are
translated at prevailing exchange rates when earned or incurred. The
fund does not isolate that portion of realized or unrealized gains or
losses resulting from changes in the foreign exchange rate on
investments from fluctuations arising from changes in the market prices
of the securities. Such gains and losses are included with the net
realized and unrealized gain or loss on investments. Net realized gains
and losses on foreign currency transactions represent net realized
exchange gains or losses on closed forward currency contracts,
disposition of foreign currencies, currency gains and losses realized
between the trade and settlement dates on securities transactions and
the difference between the amount of investment income and foreign
withholding taxes recorded on the fund's books and the U.S. dollar
equivalent amounts actually received or paid. Net unrealized
appreciation and depreciation of assets and liabilities in foreign
currencies arise from changes in the value of open forward currency
contracts and assets and liabilities other than investments at the
period end, resulting from changes in the exchange rate. Investments in
foreign securities involve certain risks, including those related to
economic instability, unfavorable political developments, and currency
fluctuations, not present with domestic investments.

E) Forward currency contracts The fund may buy and sell forward currency
contracts, which are agreements between two parties to buy and sell
currencies at a set price on a future date. These contracts are used to
protect against a decline in value relative to the U.S. dollar of the
currencies in which its portfolio securities are denominated or quoted
(or an increase in the value of a currency in which securities a fund
intends to buy are denominated, when a fund holds cash reserves and
short term investments). The U.S. dollar value of forward currency
contracts is determined using current forward currency exchange rates
supplied by a quotation service. The market value of the contract will
fluctuate with changes in currency exchange rates. The contract is
marked to market daily and the change in market value is recorded as an
unrealized gain or loss. 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. The fund could be exposed to risk if the value of the currency
changes unfavorably, if the counterparties to the contracts are unable
to meet the terms of their contracts or if the fund is unable to enter
into a closing position. Forward currency contracts outstanding at
period end are listed after The fund's portfolio.

F) 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.

G) Security lending The fund may lend securities, through its agents, to
qualified borrowers in order to earn additional income. The loans are
collateralized by cash and/or securities in an amount at least equal to
the market value of the securities loaned. The market value of
securities loaned is determined daily and any additional required
collateral is allocated to the fund on the next business day. The risk
of borrower default will be borne by the fund's agents; the fund will
bear the risk of loss with respect to the investment of the cash
collateral. Income from securities lending is included in investment
income on the Statement of operations. At August 31, 2003, the value of
securities loaned amounted to $7,224,362. The fund received cash
collateral of $7,430,328 which is pooled with collateral of other Putnam
funds into 32 issuers of high grade short-term investments.

H) 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.

I) Federal taxes It is the policy of the fund to distribute all of its
taxable 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 August 31, 2003, the fund had a capital loss carryover of $12,099,349
available to the extent allowed by tax law to offset future capital
gains, if any. The amount of the carryover and the  expiration dates
are:

Loss Carryover      Expiration
- ---------------------------------------
    $3,190,780      Aug. 31, 2010
     8,908,569      Aug. 31, 2011

Pursuant to federal income tax regulations appli cable to regulated
investment companies, the fund has elected to defer to its fiscal year
ending August 31, 2004, $4,557,476 of losses recognized during the
period November 1, 2002 to August 31, 2003.

J) Distributions to shareholders Distributions to shareholders from net
investment income are recorded by the fund on the ex-dividend date.
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 losses on wash sale transactions, foreign currency gains and losses,
post-October loss deferrals and realized gains and losses on certain
futures contracts. Reclassifications are made to the fund's capital
accounts to reflect income and gains available for distribution (or
available capital loss carryovers) under in come tax regulations. For the
year ended August 31, 2003, the fund reclassified $4,603,240 to increase
distributions in excess of net investment income and $669,036 to increase
paid-in-capital, with an de crease to  accumulated net realized losses of
$3,934,204.

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

Unrealized appreciation            $37,888,579
Unrealized depreciation             (1,800,759)
                                  ------------
Net unrealized appreciation         36,087,820
Capital loss carryforward          (12,099,349)
Post October loss                   (4,557,476)
Cost for federal income
tax purposes                      $256,530,401


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 following annual rates: 0.70% of the first $500 million
of average net assets, 0.60% of the next $500 million, 0.55% of the next
$500 million, 0.50% of the next $5 billion, 0.475% of the next $5
billion, 0.455% of the next $5 billion, 0.44% of the next $5 billion,
and 0.43% 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.

Under the subcustodian contract between the subcustodian bank and PFTC,
the subcustodian bank has a lien on the securities of the fund to the
extent permitted by the fund's investment restrictions to cover any
advances made by the sub custodian bank for the settlement of securities
purchased by the fund. At August 31, 2003, the payable to the
subcustodian bank represents the amount due for cash advanced for the
settlement of a security purchased.

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. The fund also reduced expenses through
brokerage service arrangements. For the year ended August 31, 2003, the
fund's expenses were reduced by $172,761 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $806 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 Trustees compensation and expenses in the
Statement of operations. Accrued pension liability is included in
Payable for Trustees 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, class C 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%, 1.00% and 1.00% of the average net assets
attributable to class A, class B, class C and class M shares, respectively.
The Trustees have approved payment by the fund at the annual rates of
0.25%, 1.00%, 1.00% and 0.75% of the average net assets attributable to
class A, class B, class C and class M shares, respectively.

For the year ended August 31, 2003, Putnam Retail Management, acting as
underwriter, received net commissions of $33,840 and $316 from the sale
of class A and class M shares, respectively, and received $105,114 and
$24,699 in contingent deferred sales charges from redemptions of class B
and class C shares, respectively.

A deferred sales charge of up to 1.00% and 0.65% is assessed on certain
redemptions of class A and class M shares, respectively. For the year
ended August 31, 2003, Putnam Retail Management, acting as underwriter,
received $2,131 and no monies on class A and class M redemptions,
respectively.


Note 3
Purchases and sales of securities

During the year ended August 31, 2003, cost of purchases and proceeds
from sales of investment securities other than short-term investments
aggregated $342,169,640 and $356,984,168, respectively. There were no
purchases and sales of U.S. government obligations.

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.

officers 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
