FROM THE TRUSTEES

[GRAPHIC OMITTED: PHOTO OF JOHN A. HILL AND GEORGE PUTNAM III]

Dear Fellow Shareholder:

We are pleased to report that Putnam Intermediate U.S. Government Income
Fund delivered positive results for the six months ended May 31, 2003.
However, largely because of the fund's defensive positioning, it
underperformed both its benchmark and its Lipper peer group average.
Performance details can be found on page 7.

As interest rates continued to decline during the period, the management
team believed it prudent to protect the fund's assets against an
inevitable rise in rates (and an accompanying decline in share prices),
an opinion it still holds. Although rates continued to decline,
ultimately reaching 45-year lows, the management team believes such
rates are unsustainable and will eventually begin to rise. The team
believes the fund is well positioned to accommodate such a turn. In the
following report, the management team discusses this and other
strategies. They also offer their views on the fund's prospects for the
fiscal year's second half.

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

Respectfully yours,

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

REPORT FROM FUND MANAGEMENT

* Putnam Intermediate U.S. Government Income Fund class A shares
  returned 2.88% at net asset value and -0.39% at public offering price
  for the six months ended May 31, 2003.

* Due to its more defensive positioning, the fund underperformed its
  benchmark, the Lehman Intermediate Government Bond Index, which returned
  4.70% during the same period.

* For the same reason, the fund's performance also lagged the average
  of 3.58% for its Lipper category, Lipper Short-Intermediate U.S.
  Government Funds.

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

* PERFORMANCE COMMENTARY

We believe that the fund's comparative results during this period
appropriately reflect its objective of seeking income with preservation
of capital. We structured the portfolio defensively because we were
concerned about the possible negative impact of rising interest rates on
the portfolio's value. Duration is a measure of sensitivity to interest
rates, and we took on a defensive positioning -- a relatively short
duration -- to help protect the fund from potentially higher rates (Bond
prices move in the opposite direction of interest rates). To illustrate,
we kept the fund's duration within a range of 1.5 to 1.7 years. At the
end of the period, the duration of the Lehman index was 3.25 years.
Unfortunately, interest rates continued to fall during the period,
reaching 45-year lows. Thus far, our assertion that rates will rise has
been incorrect, but we still believe that interest rates remain at
unsustainably low levels. On the positive side, fund performance was
helped by our decision to allocate significant assets to mortgage-backed
securities. We emphasized this sector in order to gather additional
coupon income, a strategy that added to the fund's return.


Fund Profile

Putnam Intermediate U.S. Government Income Fund seeks as high a level of
current income as Putnam Management believes is consistent with
preservation of capital, by allocating its assets among
intermediate-maturity U.S. Treasuries, mortgage-backed securities, and
other U.S. government agency securities. The fund may be appropriate for
investors seeking current income.


* MARKET OVERVIEW

Continued uncertainty and investor trepidation characterized the markets
during much of the period, which was marked by concern about the
direction of the U.S. economy, consumer spending, and if capital
spending by corporations would improve. Overlaying these factors was the
geopolitical uncertainty brought to bear by tenuous situations in Iraq
and North Korea. Once the invasion of Iraq reached a positive
conclusion, investors became more confident, moving some assets back
into stocks. Corporate bonds also posted a strong rebound.

The fiscal and monetary backdrop also appeared to be a positive one for
future growth. The Congress and President Bush signed the Jobs and
Growth Tax Relief Reconciliation Act of 2003, and the Federal Reserve
Board reinforced its commitment to keeping interest rates low enough to
spark a stronger recovery. We expected these events to push interest
rates higher. With investors anticipating a rebound and moving assets
out of Treasuries, we anticipated that yields would rise and bond prices
would fall. However, several factors kept yields declining, most
significantly, continued sustained demand for Treasury securities from
Asian central banks and individual investors in the United States. These
parties remained concerned about future growth as a result of ongoing
concerns related to Iraq, terrorism, North Korea, as well as the
uncertainty about what kind of effect the SARS epidemic might have on
global economic activity. With interest rates at historic lows, mortgage
refinancing continued at a torrid pace.

* STRATEGY OVERVIEW

Our investment process remains unchanged. We start by deciding whether
mortgages or comparable Treasuries are more attractive, given their
relative valuations and our broad outlook about the economy and interest
rates. Then, we choose investments within these sectors by issuer or
coupon rate by analyzing relative valuation and yields. Part of this
approach is to see if there are opportunities offered by securities that
are not included in the benchmark. During the period, we decided to
maintain an emphasis on mortgage-backed securities because of the
additional yield they offered. At the same time, we took a defensive
approach, positioning the Treasury portion of the portfolio in Treasury
bills and short-term cash equivalents, which are less sensitive to
changes in interest rates. This was done with an eye toward reducing the
fund's duration, which indicates its interest-rate sensitivity. (A
shorter duration means that the portfolio value is less likely to
decline if interest rates rise; however, if rates fall, such a portfolio
will not be able to benefit as much from the ensuing bond price
increases.) We also took advantage of yield opportunities in other
mortgage-related securities and agency debentures, because we believed
that they offered attractive yields without adding significant risk.

* HOW FUND HOLDINGS/SECTOR ALLOCATIONS  AFFECTED PERFORMANCE

Within the mortgage-backed security (MBS) sector allocation, we were
able to find significant opportunities to add additional income and help
performance. We increased the fund's MBS weighting to 70.6% (based on
the fund's net assets) by the end of the period. Declining interest
rates led to sustained prepayment activity. In this scenario, low or
falling interest rates encourage homeowners to refinance, leaving MBS
holders, such as the fund, with principal prepayments that must be
reinvested at lower prevailing rates.

Given this backdrop, we looked for segments of the market that were
generally insulated from prepayments. We initially favored 15-year MBSs
with 5.5% coupon rates issued by the Government National Mortgage
Association (Ginnie Maes) and the Federal National Mortgage Association
(Fannie Maes). As the period progressed, we moved our 15-year allocation
down the coupon scale to 5% and finally to 4.5% securities issued by the
Federal Home Loan Mortgage Corporation (Freddie Macs). Toward the end of
the period, we turned our focus to higher-coupon 30-year Fannie Maes
with 7% coupons because they offered particular value and had already
experienced significant prepayment activity. We also favored 30-year
Fannie Maes and Ginnie Maes with 5% coupons, because homeowners with
this low interest rate had little to no incentive to refinance. The fund
also benefited from investments in what are known as re-performing
mortgage loans with 30-year maturities. These are securities that have
been purchased by Fannie Mae from Ginnie Mae after homeowners have
demonstrated some difficulty in meeting their mortgage payments. Fannie
Mae then reissues the pools of mortgage securities and guarantees them.
These MBSs offered coupons in the 7.5% range, but with much slower
prepayment activity due to the slightly impaired credit of the
homeowners. As such, we believe they were attractively priced, offered
compelling yields with reduced prepayment risk, and were secured by the
backing of Fannie Mae.

Footnote reads:
*This chart shows how the fund's sector weightings have changed over the
 last six months. Weightings are shown as a percentage of net assets.
 Sectors and holdings will vary over time.


While our moves within the MBS sector helped performance, they were not
enough to offset the effects of our defensive positioning within a
falling interest-rate environment. During the period, Treasuries
outperformed MBSs as interest rates were on the decline. Our choice for
Treasury investments, Treasury bills, are offered with maturities of
three months, six months, and one year. They differ from Treasury notes,
which carry maturities of between 2 and 10 years, and Treasury bonds,
which are Treasury securities with maturities of longer than 10 years.
We focused on shorter-term Treasuries and cash equivalents in order to
shorten the duration, or interest-rate sensitivity, of the fund. We also
felt that other parts of the Treasury yield curve were more prone to
suffer price losses if interest rates rose.

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.


OF SPECIAL INTEREST

* At the time this report was being written, the Federal Home Loan
  Mortgage Corporation (Freddie Mac) was being investigated for
  allegations of accounting and management improprieties, as well as
  alleged improper use of the company's reserve account. We are monitoring
  the situation closely and will make changes to the fund's holdings if we
  believe such changes are warranted. The allegations did not affect
  performance in a material way during the semiannual period.


* THE FUND'S MANAGEMENT TEAM

The fund is managed by the Putnam Core Fixed-Income Team. The members of
the team are Kevin Cronin (Portfolio Leader), Rob Bloemker (Portfolio
Member), Carl Bell, Andrea Burke, Steve Horner, D. William Kohli, James
Prusko, Michael Salm, John Van Tassel, and David Waldman.


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 believe that economic growth will be modest going forward. More
importantly, several factors that forced interest rates lower appear to
be reversing direction. First, the federal budget is no longer in
surplus. The U.S. Treasury had been using the extra funds to buy back
debt, putting downward pressure on interest rates. Instead, there will
be a pronounced deficit going forward, made even larger by spending on
the Iraq war. The significant amount of new issuance should force rates
higher. In addition, bonds outperformed stocks from 2000 through 2002,
the first time they did so three years running since 1939-1941. The
equity market appears to be rebounding, increasing the possibility that
the bond market will experience significant outflows from investors who
had been using the safe haven of government bonds to protect their
assets while the stock market floundered. Third, uncertainty about
credit quality and risk, which resulted from the corporate accounting
scandals, appears to be dissipating. In response, the corporate bond
market has performed well recently. Further, interest rates were kept
low by the strong buying of U.S. assets by international investors who
were seeking the relative safety of the U.S. government bond market and
because of the strength of the U.S. dollar. However, the dollar has
fallen in value relative to the yen and the euro for the first time in
nine years, making U.S. assets less attractive to overseas investors.
Finally, if some sort of resolution in Iraq is achieved, we could see a
quick and significant rise in interest rates, which are currently at low
levels. Our defensive stance was constructed with all of this in mind.
While we may have been a bit early, we felt it was necessary to be
prepared instead of struggling to catch up with market forces. As it is
a rule in the fixed-income marketplace that bond prices decline when
yields rise, we will be looking to protect the fund's principal at the
same time that we look for yield opportunities to bolster returns.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. Mutual funds that
invest in government securities are not guaranteed. Mortgage-backed
securities are subject to prepayment risk.

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 3.25% and 2.00%, respectively. Class B
share returns reflect the applicable contingent deferred sales charge
(CDSC), which is 3% in the first year, declining to 1% in the fourth
year, and is eliminated thereafter. Class C shares reflect a 1% CDSC the
first year that is eliminated thereafter. Performance for classes C 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 3.25% maximum sales charge for class A
shares and 2.00% 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 3% maximum
during the first year to 1% during the fourth year. After the fourth
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).

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.

NOTES TO FINANCIAL STATEMENTS
May 31, 2003 (Unaudited)

Note 1
Significant accounting policies

Putnam Intermediate U.S. Government 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 high
current income consistent with preservation of capital, through
investments primarily in U.S. government securities.

The fund offers class A, class B, class C, class M and class Y shares.
Class A shares are sold with a maximum front-end sales charge of 3.25%.
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 four years of purchase. Class C shares have a higher
ongoing distribution fee than class B shares and 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 2.00%
and pay an ongoing distribution fee that is higher than class A shares
but lower than class B and class C shares. Class Y shares, which are
sold at net asset value, are generally subject to the same expenses as
class A, class B, class C and class M shares, but do not bear a
distribution fee. Class Y shares are sold to certain eligible purchasers
including certain defined contribution plans (including corporate IRAs),
bank trust departments and trust companies.

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, including mortgage-backed securities,
are valued on the basis of valuations provided by an independent pricing
service, approved by the Trustees. Such service providers 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. Short-term investments having remaining maturities of 60
days or less are valued at amortized cost, which approximates fair
value.

B) Joint trading account The fund may transfer uninvested cash balances,
including cash collateral received under security lending arrangements,
into a joint 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) Repurchase agreements The fund, or any joint trading account, through
its custodian, receives delivery of the underlying securities, the
market value of which at the time of purchase is required to be in an
amount at least equal to the resale price, including accrued interest.
Collateral for certain tri-party repurchase agreements is held at the
counterparty's custodian in a segregated account for the benefit of the
fund and the counterparty.Putnam Management is responsible for
determining that the value of these underlying securities is at all
times at least equal to the resale price, including accrued interest.

D) 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.

E) TBA purchase commitments The fund may enter into "TBA" (to be
announced) commitments to purchase securities for a fixed unit price at
a future date beyond customary settlement time. Although the unit price
has been established, the principal value has not been finalized.
However, the amount of the commitments will not significantly differ
from the principal amount. The fund holds, and maintains until
settlement date, cash or high-grade debt obligations in an amount
sufficient to meet the purchase price, or the fund may enter into
offsetting contracts for the forward sale of other securities it owns.
Income on the securities will not be earned until settlement date. TBA
purchase commitments may be considered securities themselves, and
involve a risk of loss if the value of the security to be purchased
declines prior to the settlement date, which risk is in addition to the
risk of decline in the value of the fund's other assets. Unsettled TBA
purchase commitments are valued at the current market value of the
underlying securities, according to the procedures described under
"Security valuation" above.

Although the fund will generally enter into TBA purchase commitments
with the intention of acquiring securities for its portfolio or for
delivery pursuant to options contracts it has entered into, the fund may
dispose of a commitment prior to settlement if Putnam Management deems
it appropriate to do so.

F) TBA sale commitments The fund may enter into TBA sale commitments to
hedge its portfolio positions or to sell mortgage-backed securities it
owns under delayed delivery arrangements. Proceeds of TBA sale
commitments are not received until the contractual settlement date.
During the time a TBA sale commitment is outstanding, equivalent
deliverable securities, or an offsetting TBA purchase commitment
deliverable on or before the sale commitment date, are held as "cover"
for the transaction.

Unsettled TBA sale commitments are valued at the current market value of
the underlying securities, generally according to the procedures
described under "Security valuation" above. The contract is
"marked-to-market" daily and the change in market value is recorded by
the fund as an unrealized gain or loss. If the TBA sale commitment is
closed through the acquisition of an offsetting purchase commitment, the
fund realizes a gain or loss. If the fund delivers securities under the
commitment, the fund realizes a gain or a loss from the sale of the
securities based upon the unit price established at the date the
commitment was entered into. TBA sale commitments outstanding at period
end are listed after The fund's portfolio.

G) 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.

The aggregate identified cost on a tax basis is $2,056,220,494,
resulting in gross unrealized appreciation and depreciation of
$14,885,377 and $655,729, respectively, or net unrealized depreciation
of $14,229,648.

H) Distributions to shareholders The fund declares a distribution each
day based upon the projected net investment income, for a specified
period, calculated as if earned pro-rata throughout the period on a
daily basis. Such distributions are recorded daily and 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

Compensation of Putnam Management, for management and investment
advisory services is paid quarterly based on the average net assets of
the fund. Such fee is based on the lesser of (i) the annual rate of
0.50% of the average net assets of the fund or (ii) 0.60% of the first
$500 million of average net assets, 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 May 31, 2003,
the fund's expenses were reduced by $39,228 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $1,945 has been allocated to the fund, and an additional fee for
each Trustees meeting attended. Trustees receive additional fees for
attendance at certain committee meetings.

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

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

The fund has adopted distribution plans (the "Plans") with respect to
its class A, class B, 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%, 0.85%, 1.00% and 0.40% of the average net assets
attributable to class A, class B, class C and class M shares,
respectively.

For the six months ended May 31, 2003, Putnam Retail Management, acting
as underwriter, received net commissions of $46,173 and $1,342 from the
sale of class A and class M shares, respectively, and received $379,617
and $7,769 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 0.40% is assessed on certain
redemptions of class A and class M shares, respectively. For the six
months ended May 31, 2003, Putnam Retail Management, acting as
underwriter, received $18,755 and no monies on class A and class M
redemptions, respectively.

Note 3
Purchases and sales of securities

During the six months ended May 31, 2003, cost of purchases and proceeds
from sales of investment securities other than U.S. government
obligations and short-term investments aggregated $1,480,447,591 and
$1,443,085,088, respectively. Purchases and sales of U.S. government
obligations aggregated $406,274,369 and $560,011,852, respectively.

of shares without a service charge. (This privilege is subject to change
or termination.)

Please note that past performance is not indicative of future results.
More recent returns may be more or less than those shown. Returns shown
for class Y shares for periods prior to their inception are derived from
the historical performance of class A shares, and are not adjusted to
reflect the initial sales charge currently applicable to class A shares.
These returns have not been adjusted to reflect differences in operating
expenses which, for class Y shares, typically are lower than the
operating expenses applicable to class A shares. All returns assume
reinvestment of distributions at net asset value. Investment return and
principal value will fluctuate so your shares, when redeemed, may be
worth more or less than their original cost. See full report for
information on comparative benchmarks. If you have questions, please
consult your fund prospectus or call Putnam toll free at 1-800-752-9894.
