Dear Fellow Shareholder:

Throughout the period ended April 30, 2005, the Federal Reserve Board's
series of gradual increases in the federal funds rate occupied much of
investors' attention. However, these increases did not begin to have a
significant impact on stock and bond prices until the early months of
the 2005 calendar year. The Fed's more restrictive monetary policy,
along with stubbornly high energy prices, has caused concern about the
sustainability of corporate profits and slowed the stock market's
momentum. Shorter-term bond prices have also been under pressure due to
worries regarding inflation. In addition, credit quality issues have
become a greater concern, particularly in early May, after the end of
the reporting period, when rating agencies downgraded bonds issued by
Ford and General Motors. Given the uncertainties of this environment,
security selection takes on even greater importance and the in-depth,
professional research and active management that mutual funds can
provide makes them an even more intelligent choice for today's
investors.

We want you to know that Putnam Investments' management team, under the
leadership of Chief Executive Officer Ed Haldeman, continues to focus on
investment performance and remains committed to putting the interests of
shareholders first. In keeping with these goals, we are including
additional disclosure about your fund's management team in this report.
Following the Outlook for Your Fund, we provide manager compensation
information that pertains to your fund. Furthermore, in this report we
provide information about the 2004 approval by the Trustees of your
fund's management contract with Putnam. See page 18 for details.

In the following pages, members of your fund's management team discuss
the fund's performance, the strategies used to pursue the fund's
investment objectives during the reporting period, and the team's plan
for responding to recent changes in the market climate.

As always, we thank you for your continuing confidence in Putnam.

Respectfully yours,

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

Performance commentary

Your fund's semiannual period was divided into a generally favorable
market environment during the first three months and a less favorable
one in the latter three. The change in atmosphere was driven by the
Federal Reserve Board (the Fed), which continued its program of gradual
interest-rate increases through February and March 2005, and expressed
greater concern about the potential for inflation. This prompted
sell-offs in all sectors of the bond market during those months;
however, sectors with higher credit risk saw greater price declines (and
corresponding yield increases). Rates began to move downward in the
final weeks of the period on news of softer growth, but the sell-off in
February and March still detracted significantly from performance for
the period. Anticipating a potential rise in rates before the period had
begun, your fund's management team had positioned the fund in a more
conservative manner by making the portfolio less sensitive to changes in
interest rates and improving its overall credit quality. As a result,
the fund's performance was in line with both its benchmark index and its
Lipper category average, based on results at net asset value (NAV, or
without sales charges).

FUND PROFILE

Putnam Income Fund seeks high current income consistent with what Putnam
Management believes to be a prudent level of risk. The fund invests in a
diversified portfolio composed mainly of corporate investment-grade
bonds, U.S. government and agency bonds, and collateralized mortgage
obligations.


Market overview

One of the most important events of the six-month period was the change
in tone from the Fed when it raised the federal funds rate in March.
This rate increase was the seventh in a series of increases that had
begun in June 2004. At the time of that first increase, the Fed's
official comment implied that future rate increases would come at a
"measured pace," and were intended to bring short-term rates back up to
more "normal" levels (from a 46-year low). As a result, long-term bond
investors were less concerned about an abrupt, sharp hike in interest
rates and focused on the economy, which was growing at a moderate pace
with low inflation. Reflecting this favorable environment, yields on
long-term bonds continued to decline through calendar 2004 and into
early 2005.

At its meetings in January, February, and March, the Fed gradually
changed its tone to reflect increased concerns about inflation. The U.S.
and international bond markets saw this change as a signal that future
rate increases could be more frequent and higher. Bonds sold off, with
the lower-quality, higher-yield bond sectors -- including emerging
markets and high-yield corporates -- experiencing the greatest price
declines (and yield increases). In April, the Commerce Department
reported lower-than-expected economic growth for the first quarter,
which brought long-term rates back down somewhat, but did not offset the
sharp rise of the previous two months.

Strategy overview

Prior to the beginning of the semiannual period, we had begun to reduce
the level of both credit risk and interest-rate risk in the portfolio --
a strategy we continued to implement over the past six months. To reduce
credit risk, we sold holdings with lower credit ratings, primarily in
the corporate bond sector, and purchased higher-rated asset-backed and
commercial mortgage-backed securities. We believed that lower-rated
bonds had become overvalued and presented an uncomfortable degree of
risk. A key measure of this risk was the spread, or difference, between
the yields on lower- and higher-quality bonds. This "credit yield
spread" had been narrowing during the 2004 calendar year. However, over
the first four months of 2005, this spread widened, reflecting an
increase in perceived risk for lower-quality bonds, and illustrating a
decline in their performance compared to higher-quality bonds. As a
result, our strategy of underweighting these securities proved
beneficial for the fund's relative returns.

To reduce sensitivity to changes in interest rates, we continued to
shorten the fund's overall duration. Duration, which is measured in
years, is the primary indicator of interest-rate sensitivity. The
shorter a bond's duration, the less sensitive its price will be to
interest-rate changes. The fund's lower interest-rate sensitivity hurt
its performance somewhat at the beginning of the period, but it paid off
during the latter months, when rates rose and the market became more
skittish. While intended as a defensive strategy, this positioning was
also beneficial for the fund's performance.

How fund holdings affected performance

During the semiannual period, interest rates fluctuated within a
relatively moderate range. In such an environment, securitized bonds, or
structured securities, tend to perform well because they typically offer
higher income than corporate bonds of comparable credit quality. They
also came with shorter maturities, so if interest rates were to rise, we
would be able to reinvest the proceeds in higher-yielding securities.
The most common type of securitized bonds are mortgage-backed securities
(MBSs) issued by the Federal National Mortgage Association (Fannie Mae)
and the Government National Mortgage Association (Ginnie Mae). Other
types of securitized bonds include asset-backed securities (ABSs), which
are typically backed by car loans and credit card payments, and
commercial mortgage-backed securities (CMBSs), which are backed by loans
on large commercial real estate projects, such as office parks or
shopping malls. Both of these sectors performed well in comparison to
investment-grade corporate bonds. The fund's holdings in home equity and
manufactured-housing ABSs performed particularly well. The fund was
underweighted in MBSs, which underperformed other types of securitized
bonds, and was overweighted in CMBSs and ABSs, which outperformed. As a
result, our strategies in these sectors were beneficial for the fund's
relative performance.

The fund's holdings of Treasury bonds underperformed most fixed-income
sectors for most of the period. However, we had allocated a smaller
portion of the portfolio to this sector than did many of the fund's
peers, so this underweighting helped relative returns.

In the investment-grade corporate bond portion of the portfolio, we
continued our efforts to reduce lower-rated holdings and replace them with
higher-rated securities, including CMBSs and ABSs. Current holdings
include bonds from the media, cable, and real estate investment trust
(REIT) areas, which have been strong performers. We also found select
opportunities in the strong-performing energy and utilities sectors. The
fund's underweight to the automotive sector was also beneficial to
performance. This industry has performed poorly due to concerns about
General Motors, which has been struggling, and because of rising interest
rates, which have hurt the financial performance of debt-laden auto
companies. The fund's underweight to GM, one of the worst-performing bonds
in the Lehman Aggregate Bond Index, also helped its relative returns.
(Shortly after the end of the period, General Motors debt was downgraded
to below-investment-grade status by Standard & Poor's.)

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.

During the period, the fund's lower returns reflected a more cautious
bond market and a more mature economic recovery. Our forecast is for
continued steady, moderate growth with a possible slight increase in
inflation. Such an environment would probably result in more short-term
interest-rate increases by the Fed and the likelihood that long-term
bond yields would continue moving upward. In such an environment, we
believe the fund's shorter duration and higher credit quality would help
it weather the impact of the higher interest rates we expect to see. Of
course, we will continue to remain vigilant about any possible
disruptions to the U.S. economy and fixed-income markets, keeping the
fund positioned defensively while remaining well diversified in a broad
range of high-quality fixed-income sectors and securities.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. Lower-rated bonds
may offer higher yields in return for more risk. 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 4.50% and 3.25%, respectively (which
for class A shares does not reflect a reduction in sales charges that
went into effect on April 1, 2005; if this reduction had been in place
for all periods indicated, returns would have been higher). Class B
share returns reflect the applicable contingent deferred sales charge
(CDSC), which is 5% in the first year, declining to 1% in the sixth
year, and is eliminated thereafter. Class C shares reflect a 1% CDSC the
first year that is eliminated thereafter. Class R shares 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 may be applied to 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 would 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 Income Fund from November 1, 2004, to April 30,
2005. 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 4/30/05.
   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 April
30, 2005, use the calculation method below. To find the value of your
investment on November 1, 2004, go to www.putnaminvestments.com and log

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 4/30/05. 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 the average of its peer
group, as defined 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.

+ Simple average of the expenses of all front-end load funds in the fund's
  Lipper peer group, calculated in accordance with Lipper's standard
  method for comparing fund expenses (excluding 12b-1 fees and without
  giving effect to any expense offset and brokerage service arrangements
  that may reduce fund expenses). This average reflects each fund's
  expenses for its most recent fiscal year available to Lipper as of
  3/31/05. To facilitate comparison, Putnam has adjusted this average to
  reflect the 12b-1 fees carried by each class of shares. The peer group
  may include funds that are significantly smaller or larger than the
  fund, which may limit the comparability of the fund's expenses to the
  simple average, which typically is higher than the asset-weighted
  average.


Understanding your fund's
portfolio turnover

Putnam funds are actively managed by teams of experts who buy and sell
securities based on intensive analysis of companies, industries,
economies, and markets. Portfolio turnover is a measure of how often a
fund's managers buy and sell securities for your fund. A portfolio
turnover of 100%, for example, means that the managers sold and replaced
securities valued at 100% of a fund's assets within a one-year period.
Funds with high turnover may be more likely to generate capital gains
and dividends that must be distributed to shareholders as taxable
income. High turnover may also cause a fund to pay more brokerage
commissions and other transaction costs, which may detract from
performance.

Funds that invest in bonds or other fixed-income instruments may have
higher turnover than funds that invest only in stocks. Short-term bond
funds tend to have higher turnover than longer-term bond funds, because
shorter-term bonds will mature or be sold more frequently than
longer-term bonds. You can use the table below to compare your fund's
turnover with the average turnover for funds in its Lipper category.

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

 * Portfolio turnover excludes certain treasury note transactions
   executed in connection with a short-term trading strategy.

   Turnover data for the fund is calculated based on the fund's fiscal-year
   period, which ends on October 31. Turnover data for the fund's Lipper
   category is calculated based on the average of the turnover of each fund
   in the category for its fiscal year ended during the indicated year.
   Fiscal years vary across funds in the Lipper category, which may limit
   the comparability of the fund's portfolio turnover rate to the Lipper
   average. Comparative data for 2004 is based on information available as
   of 3/31/05.


Risk comparison

This risk comparison is designed 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       0.16

Taxable bond
fund average           0.30

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 March 31, 2005. 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. NAV
is calculated by dividing the net assets of each class of shares by the
number of outstanding shares in the class.

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the 4.50% maximum sales charge for class A
shares (since reduced to 3.75%) and 3.25% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time
of the redemption of class B 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).

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

Trustee approval of management contract

General conclusions

The Board of Trustees of the Putnam funds oversees the management of
each fund and, as required by law, determines annually whether to
approve the continuance of each fund's management contract with Putnam
Management. In this regard the Board of Trustees, with the assistance of
its Contract Committee consisting solely of Independent Trustees,
requests and evaluates all information it deems reasonably necessary in
the circumstances. Over the course of several months beginning in March
and ending in June of 2004, the Contract Committee reviewed the
information provided by Putnam Management and other information
developed with the assistance of the Board's independent counsel and
independent staff. The Contract Committee reviewed and discussed key
aspects of this information with all of the Independent Trustees. Upon
completion of this review, the Contract Committee recommended and the
Independent Trustees approved the continuance of your fund's contract,
effective July 1, 2004.

This approval was based on the following conclusions:

* That the fee schedule currently in effect for your fund represents
  reasonable compensation in light of the nature and quality of the
  services being provided to the fund, the fees paid by competitive funds
  and the costs incurred by Putnam Management in providing such service,
  and

* That such fee schedule represents an appropriate sharing between fund
  shareholders and Putnam Management of such economies of scale as may
  exist in the management of the fund at current asset levels.

These conclusions were based on a comprehensive consideration of all
information provided to the Trustees and were not the result of any
single factor. Some of the factors that figured particularly in the
Trustees' deliberations are described below.

Model fee schedules and categories; total expenses

The Trustees, working in cooperation with Putnam Management, have
developed and implemented a series of model fee schedules for the Putnam
funds designed to ensure that each fund's management fee is consistent
with the fees for similar funds in the Putnam complex and compares
favorably with fees paid by competitive funds sponsored by other advisors.
The Trustees reviewed the model fee schedule currently in effect for the
fund, including fee levels and breakpoints, and the assignment of the fund
to a particular fee category under this structure. The Trustees also
reviewed comparative fee and expense information for competitive funds.
The Trustees concluded that no changes should be made in the fund's
current fee schedule at this time. The Trustees noted that expense ratios
for a number of Putnam funds had been increasing recently as a result of
declining net assets and the natural operation of fee breakpoints. They
noted that such expense ratio increases were currently being controlled by
expense limitations implemented in January 2004. They also noted that the
competitive landscape regarding mutual fund fees may be changing as a
result of fee reductions accepted by various other fund groups in
connection with recent regulatory settlements and greater focus on fees
and expenses in the mutual fund industry generally. The Trustees indicated
an intention to monitor these developments closely.

Economies of scale

As noted above, the Trustees concluded that the fee schedule currently
in effect for your fund represents an appropriate sharing of economies
of scale at current asset levels. The Trustees indicated their intention
to continue their ongoing consideration of economies of scale and in
particular to consider further the possible operation of such economies
in the event that a significant recovery in the equity markets or net
fund sales were to raise asset levels substantially above current
levels. In this regard, the Trustees noted that they had reviewed data
relating to the substantial increase in asset levels of the Putnam funds
that occurred during the years leading up to the market peak in 2000,
the subsequent decline in assets and the resulting impact on revenues
and expenses of Putnam Management. The Trustees also noted that recent
declines in net assets in many Putnam funds, together with significant
changes in the cost structure of Putnam Management have altered the
economics of Putnam Management's business in significant ways. The
Trustees concluded that they would monitor these changes carefully and
evaluate the resulting impact on Putnam Management's economics and the
sharing of economies of scale between the parties.

Investment performance

The quality of the investment process provided by Putnam Management
represented a major factor in the Trustees' evaluation of the quality of
services provided by Putnam Management under the Management Contracts.
The Trustees recognized that a high quality investment process -- as
measured by the experience and skills of the individuals assigned to the
management of fund portfolios, the resources made available to such
personnel, and in general the ability of Putnam Management to attract
and retain high-quality personnel -- does not guarantee favorable
investment results for every fund in every time period. The Trustees
considered the investment performance of each fund over multiple time
periods and considered information comparing the fund's performance with
various benchmarks and with the performance of competitive funds. The
Trustees noted the satisfactory investment performance of many Putnam
funds.

They also noted the disappointing investment performance of certain
funds in recent years and continued to discuss with senior management of
Putnam Management the factors contributing to such under-performance and
actions being taken to improve performance. The Trustees recognized
that, in recent years, Putnam Management has made significant changes in
its investment personnel and processes and in the fund product line in
an effort to address areas of underperformance. The Trustees indicated
their intention to continue to monitor performance trends to assess the
effectiveness of these changes and to evaluate whether additional
remedial changes are warranted. As a general matter, the Trustees
concluded that consultation between the Trustees and Putnam Management
represents the most effective way to address investment performance
problems. The Trustees believe that investors in the Putnam funds and
their financial advisors have, as a general matter, effectively placed
their trust in the Putnam organization, under the supervision of the
funds' Trustees, to make appropriate decisions regarding the management
of the funds. The Trustees believe that the termination of the
Management Contract and engagement of a new investment adviser for
under-performing funds, with all the attendant disruptions, would not
serve the interests of fund shareholders at this time and would not
necessarily provide any greater assurance of improved investment
performance.

Brokerage and soft-dollar allocations; other benefits

The Trustees considered various potential benefits that Putnam
Management may receive in connection with the services it provides under
the Management Contract with your fund. These include principally
benefits related to brokerage and soft-dollar allocations, which pertain
mainly to funds investing in equity securities. The Trustees believe
that soft-dollar credits and other potential benefits associated with
the allocation of fund brokerage represent assets of the funds that
should be used for the benefit of fund shareholders. The Trustees noted
recent trends in the allocation of fund brokerage, including commission
costs, the allocation of brokerage to firms that provide research
services to Putnam Management, and the sources and application of
available soft-dollar credits. Effective December 31, 2003, reflecting a
decision made by the Trustees earlier that year, Putnam Management
ceased allocating brokerage in connection with the sale of fund shares.
In addition, in preparing its budget for commission allocations in 2004,
Putnam Management voluntarily reduced substantially the allocation of
brokerage commissions to acquire research services from third-party
service providers. In light of evolving best practices in the mutual
fund industry, the Trustees concluded that this practice should be
further curtailed and possibly eliminated in the near future. The
Trustees indicated that they would continue to monitor the allocation of
the funds' brokerage to ensure that the principle of "best price and
execution" remains paramount in the portfolio trading process.

Comparison of retail and institutional fee schedules

The information examined by the Trustees as part of the annual contract
reviews included information regarding fees charged by Putnam Management
and its affiliates to institutional clients such as defined benefit
pension plans and college endowments. This information included
comparison of such fees with fees charged to the Putnam funds, as well
as a detailed assessment of the differences in the services provided to
these two types of clients. The Trustees devoted special attention to
these issues and reviewed recent articles by critics of mutual fund
fees, articles by the ICI defending such fee differences, and relevant
guidance provided by decisions of the courts. The Trustees observed, in
this regard, that the differences in fee rates between institutional
clients and mutual funds are by no means uniform when examined by
individual asset sectors, suggesting that differences in the pricing of
investment management services to these types of clients reflects to a
substantial degree historical competitive forces operating in separate
market places. In reaching their conclusions, the Trustees considered
the fact that fee rates across all asset sectors are higher on average
for mutual funds than for institutional clients, and also considered the
differences between the services that Putnam provides to the Putnam
funds and those that it provides to institutional clients of the firm.

Settlement of regulatory charges related to market timing

Finally, in reaching their conclusions, the Trustees considered all
matters pertinent to the administrative charges filed against Putnam
Management by the SEC and the Commonwealth of Massachusetts in October
2003 relating to market timing, the firm's settlement of those charges,
and the conclusions and recommendations of the Trustees' Audit and
Pricing Committee based on its review of these matters. The Trustees
considered the actions taken by the owner of Putnam Management and its
new senior management to terminate or discipline the individuals
involved, to implement new compliance systems, to indemnify the funds
against all costs and liabilities related to these matters, and
otherwise to ensure that the interests of the funds and their
shareholders are fully protected. The Trustees noted that, in addition
to the settlements of the regulatory charges which will provide
comprehensive restitution for any losses suffered by shareholders, the
new senior management of Putnam Management has moved aggressively to
control expense ratios of funds affected by market timing, to reduce
charges to new investors, to improve disclosure of fees and expenses,
and to emphasize the paramount role of investment performance in
achieving shareholders' investment goals.


Other information for shareholders

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.

Proxy voting

Putnam is committed to managing our mutual funds in the best interests
of our shareholders. The Putnam funds' proxy voting guidelines and
procedures, as well as information regarding how your fund voted proxies
relating to portfolio securities during the 12-month period ended June
30, 2004, are available on the Putnam Individual Investor Web site,
www.putnaminvestments.com/individual, and on the SEC's Web site,
www.sec.gov. If you have questions about finding forms on the SEC's Web
site, you may call the SEC at 1-800-SEC-0330. You may also obtain the
Putnam funds' proxy voting guidelines and procedures at no charge by
calling Putnam's Shareholder Services at 1-800-225-1581.

Fund portfolio holdings

For periods ending on or after July 9, 2004, the fund will file a
complete schedule of its portfolio holdings with the SEC for the first
and third quarters of each fiscal year on Form N-Q. Shareholders may
obtain the fund's Forms N-Q on the SEC's Web site at www.sec.gov. In
addition, the fund's Forms N-Q may be reviewed and copied at the SEC's
public reference room in Washington, D.C. You may call the SEC at
1-800-SEC-0330 for information about the SEC's Web site or the operation
of the public reference room.


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 the fund's net investment gain or loss, 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
April 30, 2005 (Unaudited)

Note 1
Significant accounting policies

Putnam Income Fund (the "fund"), a Massachusetts business trust, 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 what Putnam Investment Management, LLC
("Putnam Management"), the fund's manager, an indirect wholly-owned
subsidiary of Putnam, LLC, believes to be prudent risk. The fund invests
in a portfolio of debt securities, both government and corporate
obligations, and may invest in preferred stocks and common stocks.

The fund offers class A, class B, class C, class M, class R and class Y
shares. Class A and class M shares are sold with a maximum front-end
sales charge of 3.75% and 3.25%, respectively, and do not pay a
contingent deferred sales charge. Prior to April 1, 2005 the maximum
front-end sales charge for class A shares was 4.50%. Class B shares,
which convert to class A shares after approximately eight years, do not
pay a front-end sales charge 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 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 R shares, which are
offered to qualified employee-benefit plans, are sold without a
front-end sales charge or a contingent deferred sales charge. The
expenses for class A, class B, class C, class M and class R shares may
differ based on each class' distribution fee, which is identified in
Note 2. 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,
trust companies, other Putnam funds and products and certain college
savings plans.

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. The redemption fee is accounted for as an
addition to paid-in-capital.

Investment income, realized and unrealized gains and losses and expenses
of the fund are borne pro-rata based on the relative net assets of each
class to the total net assets of the fund, except that each class bears
expenses unique to that class (including the distribution fees
applicable to such classes). 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 Market quotations are not considered to be readily
available for certain debt obligations; such investments are valued at
fair value on the basis of valuations furnished by an independent pricing
service or dealers, approved by the Trustees. Such services or dealers
determine valuations for normal institutional-size trading units of such
securities using methods based on market transactions for comparable
securities and various relationships, generally recognized by
institutional traders, between securities. Many securities markets and
exchanges outside the U.S. close prior to the close of the New York Stock
Exchange and therefore the closing prices for securities in such markets
or on such exchanges may not fully reflect events that occur after such
close but before the close of the New York Stock Exchange. Accordingly, on
certain days, the fund will fair value foreign securities taking into
account multiple factors, including movements in the U.S. securities
markets. The number of days on which fair value prices will be used will
depend on market activity and it is possible that fair value prices will
be used by the fund to a significant extent. Securities quoted in foreign
currencies 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 certain restricted securities, are valued at fair
value following procedures approved by the Trustees. Such valuations and
procedures are reviewed periodically by the Trustees.

B) Joint trading account Pursuant to an exemptive order from the
Securities and Exchange Commission (the "SEC"), 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 Management. These balances may be invested in
issues 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) 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. If a written call
option is exercised, the premium originally received is recorded as an
addition to sales proceeds. If a written put option is exercised, the
premium originally received is recorded as a reduction to the cost of
investments.

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) Total return swap contracts The fund may enter into total return swap
contracts, which are arrangements to exchange a market-linked return for
a periodic payment, both based on a notional principal amount. To the
extent that the total return of the security or index underlying the
transaction exceeds or falls short of the offsetting interest rate
obligation, the fund will receive a payment from or make a payment to
the counterparty. Total return 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 in the price of the underlying security or index, the
possibility that there is no liquid market for these agreements or that
the counterparty may default on its obligation to perform. Risk of loss
may exceed amounts recognized on the statement of assets and
liabilities. Total return swap contracts outstanding at period end, if
any, are listed after the fund's portfolio.

G) 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. Risk of loss 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.

H) Credit default contracts The fund may enter into credit default
contracts where one party, the protection buyer, makes an upfront or
periodic payment to a counter party, the protection seller, in exchange
for the right to receive a contingent payment. The maximum amount of the
payment may equal the notional amount, at par, of the underlying index
or security as a result of a related credit event. An upfront payment
received by the fund, as the protection seller, is recorded as a
liability on the fund's books. An upfront payment made by the fund, as
the protection buyer, is recorded as an asset on the fund's books.
Periodic payments received or paid by the fund are recorded as realized
gains or losses. The credit default 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 as a
result of a credit event or termination of the contract are recognized,
net of a proportional amount of the upfront payment, as realized gains
or losses. In addition to bearing the risk that the credit event will
occur, the fund could be exposed to market risk due to unfavorable
changes in interest rates or in the price of the underlying security or
index, the possibility that the fund may be unable to close out its
position at the same time or at the same price as if it had purchased
comparable publicly traded securities or that the counterparty may
default on its obligation to perform. Risks of loss may exceed amounts
recognized on the statement of assets and liabilities. Credit default
contracts outstanding at period end, if any, are listed after the fund's
portfolio.

I) 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.

J) 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.

K) Dollar rolls To enhance returns, the fund may enter into dollar rolls
(principally using TBAs) in which the fund sells securities for delivery
in the current month and simultaneously contracts to purchase similar
securities on a specified future date. During the period between the
sale and subsequent purchase, the fund will not be entitled to receive
income and principal payments on the securities sold. The fund will,
however, retain the difference between the initial sales price and the
forward price for the future purchase. The fund will also be able to
earn interest on the cash proceeds that are received from the initial
sale. The fund may be exposed to market or credit risk if the price of
the security changes unfavorably or the counterparty fails to perform
under the terms of the agreement.

L) 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 April 30, 2005, the value of
securities loaned amounted to $17,429,546. The fund received cash
collateral of $17,908,748, which is pooled with collateral of other
Putnam funds into 17 issuers of high-grade, short-term investments.

M) 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 of 1986 (the "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 Code, as amended. Therefore, no provision has
been made for federal taxes on income, capital gains or unrealized
appreciation on securities held nor for excise tax on income and capital
gains.

At October 31, 2004, the fund had a capital loss carryover of
$90,691,223 available to the extent allowed by the Code to offset future
net capital gain, if any. The amount of the carryover and the expiration
dates are:

Loss Carryover  Expiration
- --------------------------------
   $81,110,899  October 31, 2008
     9,580,324  October 31, 2009

The aggregate identified cost on a tax basis is $3,646,167,200,
resulting in gross unrealized appreciation and depreciation of
$40,064,057 and $58,119,041, respectively, or net unrealized
depreciation of $18,054,984.

N) 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. 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 following annual rates: 0.65% of the first $500 million
of average net assets, 0.55% of the next $500 million, 0.50% of the next
$500 million, 0.45% of the next $5 billion, 0.425% of the next $5
billion, 0.405% of the next $5 billion, 0.39% of the next $5 billion and
0.38% thereafter.

Putnam Management has agreed to waive fees and reimburse expenses of the
fund through October 31, 2005, to the extent necessary to ensure that
the fund's expenses do not exceed the average expenses of the front-end
load funds viewed by Lipper, Inc. as having the same investment
classification or objective as the fund. The expense reimbursement is
based on a comparison of the fund's expenses with the average annualized
operating expenses of the funds in its Lipper peer group for each
calendar quarter during the fund's last fiscal year, excluding 12b-1
fees and without giving effect to any expense offset and brokerage
service arrangements that may reduce fund expenses. For the period ended
April 30, 2005, Putnam Management waived $163,522 of its management fee
from the fund.

For the period ended April 30, 2005, Putnam Management has assumed
$20,406 of legal, shareholder servicing and communication, audit and
Trustee fees incurred by the fund in connection with certain legal and
regulatory matters (including those described in Note 6).

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 ended April 30, 2005, the
fund paid PFTC $2,826,300 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 April 30, 2005,
the fund's expenses were reduced by $243,220 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $3,417, 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 Trustees have terminated the Pension Plan with
respect to any Trustee first elected after 2003.

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%, 1.00%, 1.00%, 0.50% 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 April 30, 2005, Putnam Retail Management,
acting as underwriter, received net commissions of $33,269 and $8,378
from the sale of class A and class M shares, respectively, and received
$275,911 and $800 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 April 30, 2005,
Putnam Retail Management, acting as underwriter, received $763 and no
monies on class A and class M redemptions, respectively.

Note 3
Purchases and sales of securities

During the six months ended April 30, 2005, cost of purchases and
proceeds from sales of investment securities other than U.S. government
securities and short-term investments aggregated $3,786,822,910 and
$3,398,000,766, respectively. Purchases and sales of U.S. government
securities aggregated $37,925,838 and $89,882,159, respectively.

Investment in Putnam Prime Money Market Fund

Pursuant to an exemptive order from the Securities and Exchange
Commission, the fund invests in Putnam Prime Money Market Fund, an
open-end management investment company managed by Putnam Management.
Management fees paid by the fund are reduced by an amount equal to the
management and administrative services fees paid by Putnam Prime Money
Market Fund with respect to assets invested by the fund in Putnam Prime
Money Market Fund. For the period ended April 30, 2005, management fees
paid were reduced by $339,721 relating to the fund's investment in
Putnam Prime Money Market Fund. Income distributions earned by the fund
are recorded as income in the statement of operations and totaled
$4,888,048 for the period ended April 30, 2005. During the period ended
April 30, 2005, cost of purchases and cost of sales of investments in
Putnam Prime Money Market Fund aggregated $657,914,819 and $598,442,758,
respectively.

Note 6
Regulatory matters and litigation

Putnam Management has entered into agreements with the Securities and
Exchange Commission and the Massachusetts Securities Division settling
charges connected 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.
Pursuant to these settlement agreements, Putnam Management will pay a
total of $193.5 million in penalties and restitution, with $153.5
million being paid to shareholders and the funds. The restitution amount
will be allocated to shareholders pursuant to a plan developed by an
independent consultant, with payments to shareholders currently expected
by the end of the summer.

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 will bear any costs incurred by Putnam funds in
connection with these lawsuits. 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.

Putnam Investments has recorded a charge of $30 million for the
estimated cost that it believes will be necessary to address issues
relating to the calculation of certain amounts paid by the Putnam mutual
funds in previous years. The previous payments were cost reimbursements
by the Putnam funds to Putnam for transfer agent services relating to
defined contribution operations. Putnam currently anticipates that any
payments made by Putnam related to this issue will be paid to the Putnam
funds. Review of this issue is ongoing.

Data represents past performance. Past performance does not guarantee future
results. More recent returns may be less or more than those shown.
Investment return and principal value will fluctuate and you may have a gain
or a loss when you sell your shares. For the most recent month-end
performance, please visit www.putnaminvestments.com.

Performance assumes reinvestment of distributions and does not account for
taxes. Returns shown for class Y shares for periods prior to their inception
(6/16/94) 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. Returns have not been adjusted to reflect differences in
operating expenses which, for class Y shares, are lower than the operating
expenses applicable to class A shares. 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.

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

A short-term trading fee of up to 2% may apply.
