Dear Fellow Shareholder:

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

In a challenging environment for fixed-income investments, Putnam
Intermediate U.S. Government Income Fund generated flat returns at net
asset value for the six months ended May 31, 2004. This return lagged
that of the fund's benchmark index, primarily due to defensive
positioning designed to protect the portfolio's principal. However, it
closely matched the performance of the Lipper peer group average for the
period. Details are shown on the facing page.

As always, we appreciate your support of Putnam Investments.

Respectfully yours,

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

Report from Fund Management

Fund highlights

 * Putnam Intermediate U.S. Government Income Fund class A shares
   returned 0.00% at net asset value (NAV) and -3.18% at public offering
   price (POP) for the six months ended May 31, 2004.

 * The fund underperformed its benchmark, the Lehman Intermediate
   Government Bond Index, which advanced 0.38% during the same period.
   Portfolio management strategies designed to protect the fund's principal
   detracted from total return.

 * The fund's performance at NAV was closely in line with the 0.06%
   average return for its Lipper category, Short-Intermediate U.S.
   Government Funds.

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

Performance commentary

After a three-year bull run, the upward momentum of U.S. bond markets
flagged in the six-month period under review. Investors' concerns about
inflation and potential erosion of bond prices were renewed amid growing
signs of U.S economic strength and expectations that the Federal Reserve
Board would soon begin to lift short-term interest rates. Bond-market
returns for the period barely edged into positive territory.

While Putnam Intermediate U.S. Government Income Fund's absolute returns
for the first half of its 2004 fiscal year may appear somewhat
disappointing, they should be considered in the context of an investment
environment unfavorable to bonds. In fact, one of the main reasons that
the fund's return fell modestly short of the benchmark for the period
was our conservative positioning of the portfolio to protect against
loss of principal in this negative climate. More details on this and
other fund strategies follow in the subsequent sections of this report.

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

An overview of fixed-income markets for the first six months of the
fund's fiscal year can be given in two parts. From December through
March, disappointing job growth, lingering excess manufacturing
capacity, and a resurgence in global terrorism shook investors'
confidence in U.S. economic recovery. Bonds rallied in this environment,
as many market participants believed that the Fed would delay raising
interest rates in the face of continued economic softness. Further
support for U.S. bond markets, particularly Treasuries, came from
massive purchases on behalf of Asian central banks, primarily the Bank
of Japan.

In early April, however, yields reversed direction and began a rapid
rise. Investors increasingly became convinced that the Fed, spurred by
signs of sustained economic growth and nascent inflationary pressures,
would raise interest rates sooner than had been previously anticipated.
Bond prices, which move in the opposite direction of yields, fell
broadly and steeply. The upward momentum in yields (and downward trend
in bond prices) moderated in the final weeks of the period, however, on
a series of disappointing U.S. economic data releases as well as
concerns over intensified terrorism threats and violence in Iraq.

For the period as a whole, bond markets posted minuscule gains.
Treasuries underperformed other market sectors, while mortgage-backed
securities (MBSs) benefited as mortgage refinancing activity abated.

Strategy overview

The fund's investment approach is to assess the relative attractiveness
of the different types of U.S. government securities -- U.S. Treasuries,
mortgage-backed securities (MBSs), and other government agency
obligations -- given macroeconomic conditions and our interest-rate
outlook. We then choose securities within these sectors by analyzing
their yields and maturities, within the specified short- to
intermediate-maturity mandate outlined in the fund's prospectus. The
increased allocation to Treasuries that took place over the course of
the period is a natural result of this investment process -- as the fund
benefited from strong performance in the MBS sector, we also began to
see better relative values in the Treasury sector and shifted the
portfolio's emphasis accordingly.

During the period, we expected interest rates to begin rising from very
low levels as the economy continued to expand and inflationary pressures
started to build. Therefore we kept the portfolio's duration
consistently short to protect against loss of principal. (Duration is a
measure of sensitivity to interest-rate movements; the shorter a
portfolio's duration, the less its value will fall if rates rise.) What
we predicted did eventually occur, but later and to a lesser degree than
we had forecast. For much of the period, rates remained at historic lows
as poor reported job growth made investors skeptical about a sustained
economic recovery. That view finally changed and rates turned up as the
data on jobs dramatically improved in April and May.

As intended, the portfolio's short duration helped protect against
capital loss in the period, but this benefit was more than offset by the
lower income generated by the shorter-maturity, lower-yielding
securities emphasized in the portfolio.

How fund holdings affected performance

Throughout the period, the portfolio had a shorter, more defensive
duration than that of the benchmark and of the average for funds in its
peer group. This positioning impaired performance during the period's
first four months, when interest rates confounded market expectations by
continuing to fall even as economic growth heated up. However, this
defensive position helped protect the value of the portfolio in April
and May as rates began to rise.

We began moving portfolio duration closer to neutral (relative to the
benchmark index) as rates began to climb toward period-end. Higher bond
yields meant that the portfolio's holdings were generating more income,
providing a cushion against further bond-price declines; furthermore, as
rates rose, in our view the probable size of future rate increases
correspondingly began to shrink.

In terms of sector allocation, we consistently emphasized MBSs over
government agency securities during the period. The market for MBSs is
much larger and deeper than that for agencies; there is also relatively
greater opportunity for adding value through security selection by
choosing among instruments that reflect differing prepayment
assumptions. Furthermore, MBSs, which by definition are backed by
mortgage obligations and do not rely entirely on the issuing agency's
credit for repayment, are less vulnerable than unsecured agency bonds to
negative news about individual issuers. Within MBS holdings, an exposure
to reperforming mortgage loans (previously impaired credits which have
been strengthened through restructuring and issuer guarantees) aided
returns.

Footnote reads:
This chart compares changes in the fund's duration (a measure of its
sensitivity to interest-rate changes) and its average effective maturity
(a weighted average of the holdings' maturities).

Average effective maturity also takes into account put and call
features, where applicable, and reflects prepayments for mortgage-backed
securities.

During the period, we emphasized 15-year over 30-year MBSs. Furthermore,
in the shorter-term portion of the portfolio, we focused primarily on
MBSs instead of agencies. Fifteen-year securities carry less prepayment
risk, so they tend to be less volatile than 30-year issues. However,
this positioning constrained relative performance as 30-year mortgages
outperformed 15-year mortgages for the period.

In contrast to our bias toward shorter-maturity MBSs, we favored
agencies and Treasuries, especially 10-year Treasury notes, in the
longer maturities. We felt agencies in that range were attractively
priced. Within the fund's Treasury allocation, the maturity profile was
barbelled; that is, holdings were concentrated in the shorter- and
longer-maturity areas of the yield curve.

Within the MBS allocation, we generally preferred securities issued by
the Federal National Mortgage Association (Fannie Mae) over those issued
by the Federal Home Loan Mortgage Corporation (Freddie Mac) due to
relatively attractive valuation and liquidity. The market for Fannie
Mae-issued securities is deeper and more liquid than Freddie Mac-issued
instruments, typically resulting in lower transaction costs.

Over the course of the period, we favored discounted or premium-priced
bonds over those that were par-priced; that is, priced at the face value
stated on the bond. Investors find it easier to value par bonds, which
increases demand and prices for those instruments. We feel we have
expertise in handling the extra prepayment risk that goes with
discounted and premium bonds, enabling us to add value through security
selection in those market segments.

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.

U.S. economic expansion has become more entrenched and inflation
apparently has turned up with more vigor than expected. In these
circumstances, we have been expecting that the Fed will soon begin
raising interest rates in order to ward off inflation (and this did, in
fact, take place after the end of the period). Although inflation has
accelerated, it is still mild. This gives the Fed room to lift rates
gradually, minimizing the risk to the economic expansion that this
transition might produce through the reaction of financial markets. In
the context of our outlook for growth and inflation, we believe that
should the federal funds rate rise to approximately 2% in the first half
of 2005, this would accomplish the removal of extraordinary  stimulus
and still support a healthy ongoing expansion.

Given the potential for a continued upward trend in interest rates, we
plan to keep the fund slightly defensive; in other words, we seek to
maintain a short-to-neutral duration profile relative to the benchmark.
Earlier this year, when rates were at 45-year lows, we felt that
maintaining a shorter portfolio duration was of paramount importance to
the fund. Going forward, we expect to be more flexible and tactical with
the portfolio's duration positioning. In terms of sector allocations, we
continue to favor MBSs toward the shorter end of the yield curve and
agency securities and Treasuries toward the longer end of the curve.

In future months, we will continue to balance our efforts to take
advantage of the income opportunities that will accompany rising
interest rates with our efforts to preserve capital and maintain a
prudent level of risk exposure.

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. Mutual funds that invest in
bonds are subject to certain risks, including interest-rate risk, credit
risk, and inflation risk. As interest rates rise, the prices of bonds
fall. Long-term bonds are more exposed to interest-rate risk than
short-term bonds. Unlike bonds, bond funds have ongoing fees and
expenses.

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. Class R share returns have no initial sales
charge or CDSC. Performance for class B, C, M, and R shares before their
inception is derived from the historical performance of class A shares,
adjusted for the applicable sales charge (or CDSC) and higher  operating
expenses for such shares.

For a portion of the period, this fund limited expenses, without which
returns would have been lower.

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

Understanding your
fund's expenses

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

Review your fund's expenses

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

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

Estimate the expenses you paid

To estimate the ongoing expenses you paid for the six months ended May 31,
2004, use the calculation method below. To find the value of your
investment on December 1, 2003, go to www.putnaminvestments.com and log on
to your account. Click on the "Transaction History" tab in your Daily
Statement and enter 12/01/2003 in both the "from" and "to" fields.

Comparing your fund's expenses with those of other funds

Using the SEC's method to compare expenses

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

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

Using industry averages to compare expenses

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

- ------------------------------------------------------------------------------

- ------------------------------------------------------------------------------

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

Risk comparison

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


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

MORNINGSTAR [REGISTRATION MARK] RISK

Fund's Overall
Morningstar Risk   0.08

Taxable bond
fund average       0.33

0%   Increasing Risk   100%

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

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

Terms and definitions

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

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

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the 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).

Class R shares are not subject to an initial sales charge or CDSC and
are available only to certain defined  contribution plans.

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

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, 2004 (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, class R and class Y
shares. The fund began offering class R shares on December 1, 2003.
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, class M and class R 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 A, class B, class M and class R
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, class C and class
R shares. Class R shares are sold without a front-end sales charge and
pay an ongoing distribution fee that is higher than class A and class M
shares, but lower than class B and class C shares. Class R shares are
offered to qualified employee-benefit plans. Class Y shares, which are
sold at net asset value, are generally subject to the same expenses as
class A, class B, class C, class M and class R 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.

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

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

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

A) Security valuation Investments, including mortgage backed securities,
are valued at fair value 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 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) Futures and options contracts The fund may use futures and options
contracts to hedge against changes in the values of securities the fund
owns or expects to purchase. The fund may also write options on
securities it owns or in which it may invest to increase its current
returns. The potential risk to the fund is that the change in value of
futures and options contracts may not correspond to the change in value
of the hedged instruments. In addition, losses may arise from changes in
the value of the underlying instruments, if there is an illiquid
secondary market for the contracts, or if the counterparty to the
contract is unable to perform. Risks may exceed amounts recognized on
the statement of assets and liabilities. When the contract is closed,
the fund records a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the
time it was closed. Realized gains and losses on purchased options are
included in realized gains and losses on investment securities.

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

F) Interest rate swap contracts The fund may enter into interest rate
swap contracts, which are arrangements between two parties to exchange
cash flows based on a notional principal amount, to manage the fund's
exposure to interest rates. Interest rate swap contracts are marked to
market daily based upon quotations from market makers and the change, if
any, is recorded as unrealized gain or loss. Payments received or made
are recorded as realized gains or loss. The fund could be exposed to
credit or market risk due to unfavorable changes in the fluctuation of
interest rates or if the counterparty defaults on its obligation to
perform. Risks may exceed amounts recognized on the statement of assets
and liabilities. Interest rate swap contracts outstanding at period end,
if any, are listed after the fund's portfolio.

G) 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 fair value of the underlying
securities, 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.

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.

H) 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 fair 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, if any, are listed
after the fund's portfolio.

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 (the "Code"), as amended.
Therefore, no provision has been made for federal taxes on income,
capital gains or unrealized appreciation on securities held nor for
excise tax on income and capital gains.

The aggregate identified cost on a tax basis is $862,462,457, resulting
in gross unrealized  appreciation and depreciation of $2,011,631 and
$7,548,581, respectively, or net unrealized  depreciation of $5,536,950.

J) 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

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) 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.

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

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

Custodial functions for the fund's assets are provided by Putnam
Fiduciary Trust Company ("PFTC"), a subsidiary of Putnam, LLC. Putnam
Investor Services, a division of PFTC, provides investor servicing agent
functions to the fund. During the six months May 31, 2004, the fund paid
PFTC $1,045,693 for these services.

The fund has entered into an arrangement with PFTC whereby credits
realized as a result of uninvested cash balances are used to reduce a
portion of the fund's expenses. For the six months ended May 31, 2004,
the fund's expenses were reduced by $19,742 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $1,248 as a quarterly retainer, has been allocated to the fund,
and an additional fee for each Trustees meeting attended. Trustees
receive additional fees for attendance at certain committee meetings.

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

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

The fund has adopted distribution plans (the "Plans") with respect to
its class A, class B, class C, class M and class R shares pursuant to
Rule 12b-1 under the Investment Company Act of 1940. The purpose of the
Plans is to compensate Putnam Retail Management, a wholly-owned
subsidiary of Putnam, LLC and Putnam Retail Management GP, Inc., for
services provided and expenses incurred in distributing shares of the
fund. The Plans provide for payments by the fund to Putnam Retail
Management at an annual rate of up to 0.35%, 1.00%, 1.00%, 1.00% and
1.00% of the average net assets attributable to class A, class B, class
C, class M and class R shares, respectively. The Trustees have approved
payment by the fund at an annual rate of 0.25%, 0.85%, 1.00%, 0.40% and
0.50% of the average net assets attributable to class A, class B, class
C, class M and class R shares, respectively.

For the six months ended May 31, 2004, Putnam Retail Management, acting
as underwriter, received net commissions of $12,132 and $430 from the
sale of class A and class M shares, respectively, and received $400,151
and $11,588 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, 2004,
Putnam Retail Management, acting as underwriter, received $3,021 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, 2004, cost of purchases and proceeds
from sales of investment securities other than U.S. government
securities and short-term investments aggregated $604,698,233 and
$945,952,216, respectively. Purchases and sales of U.S. government
securities aggregated $461,615,145 and $273,580,382, respectively.

Note 4
Capital shares

At May 31, 2004, there was an unlimited number of shares of beneficial
interest authorized. Transactions in capital shares were as follows:

At May 31, 2004, Putnam, LLC owned 196 class R shares of the fund
(9.8% of class R shares outstanding), valued at $1,000.

Note 5
Regulatory matters and litigation

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

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

For the period ended May 31, 2004, Putnam Management has assumed $18,365
of legal, shareholder servicing and communication, audit, and Trustee
fees incurred by the Fund in connection with these matters.

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


Putnam puts your interests first

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

Cost-cutting initiatives

Reduced sales charges

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

Lower class B purchase

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

Ongoing expenses will be limited

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

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

Improved disclosure

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

Protecting investors' interests

New short-term trading fee introduced

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

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

   applied to shares exchanged or sold within 5 days of purchase.

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

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

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

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

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