Putnam U.S. Government Income Trust Item 1. Report to Stockholders: - ------------------------------- The following is a copy of the report transmitted to stockholders pursuant to Rule 30e-1 under the Investment Company Act of 1940: ANNUAL REPORT ON PERFORMANCE AND OUTLOOK 9-30-03 [GRAPHIC OMITTED: BASEBALL CARD] [SCALE LOGO OMITTED] From the Trustees [GRAPHIC OMITTED: PHOTO OF JOHN A. HILL AND GEORGE PUTNAM, III] John A. Hill and George Putnam, III Dear Fellow Shareholder: You may have seen media coverage of market timing allegations involving Putnam Investments. A separate letter has been sent to you detailing the steps being taken by Putnam Investments to address these matters. In addition, the Board of Trustees of The Putnam Funds is conducting an independent investigation of these issues. When that investigation is complete, we will report to you on the steps we are taking to make sure that nothing like this happens in the future. We will, of course, ensure that your fund is fully compensated for any losses resulting from improper trading activity at Putnam. We appreciate your loyalty and want you to know that we intend to restore full confidence in Putnam, an organization that aspires to the highest ethical and business standards. The balance of this report focuses on the performance of your fund. We are pleased to bring you this report on the positive performance at net asset value of Putnam U.S. Government Income Trust for the fiscal year ended September 30, 2003. The fund slightly underperformed its Lipper category average during the period, and underperformed its benchmark index. The details are shown on the facing page. Strong performance during the fiscal year's third quarter was almost entirely responsible for the positive results at net asset value at the end of the period. We also believe it is important to point out that the management team had positioned the portfolio defensively in response to the uncertainties present in the challenging market environment, and this positioning contributed to the outcome for the full fiscal year. Unfortunately, as interest rates continued their decline and mortgage repayments remained high, it became necessary to adjust the fund's dividend. Details are on page 5. Respectfully yours, /S/ JOHN A. HILL /S/ GEORGE PUTNAM, III John A. Hill George Putnam, III Chairman of the Trustees President of the Funds November 19, 2003 Report from Fund Management Fund highlights * Putnam U.S. Government Income Trust class A shares returned 2.52% at net asset value and -2.35% at public offering price for the 12 months ended September 30, 2003. * Due to its emphasis on defensive positioning, the fund underperformed its benchmark, the Lehman GNMA Index, which returned 3.25% during the same period. * The fund slightly underperformed the average for its Lipper category, GNMA Funds, which was 2.62%. * The fund's dividend was reduced three times over the course of the fiscal year. See page 5 for more details. * Effective January 21, 2003, the fund's investment policy was modified. See page 5 for more details. * See the Performance Summary beginning on page 7 for complete fund performance, comparative performance, and Lipper data. Performance commentary During much of the fiscal year, we were concerned about the possibility of rising interest rates and their impact on the portfolio's value. Since yields move in the opposite direction of bond prices, an important part of our positioning strategy for the period was to reduce the fund's sensitivity to changes in interest rates relative to its benchmark and peer group. It appears that we were a bit early with this approach, as rates initially continued to decline. However, from mid June through late August, the bond market encountered a significant correction, with rates on the rise and bond prices falling. With its defensive positioning, your fund enjoyed significant outperformance relative to the index and the Lipper group during the third quarter. However, these results were not strong enough to offset the decline experienced during the first nine months of the fund's fiscal year. FUND PROFILE Putnam U.S. Government Income Trust seeks current income by investing in U.S. government securities, such as Government National Mortgage Association certificates (Ginnie Maes), Federal National Mortgage Association certificates (Fannie Maes), Federal Home Loan Mortgage Corporation certificates (Freddie Macs), and U.S. Treasury securities. While not guaranteed by the U.S. government, Ginnie Maes, Fannie Maes, and Freddie Macs are generally high quality and typically provide higher yields than Treasury securities of similar maturities. The fund is designed primarily for investors seeking income, but it can also lower volatility in a well-diversified portfolio. Market overview There was a sharp change in market sentiment during the fiscal year. Early on, investors were concerned about the direction of the U.S. economy and favored the relative security offered by U.S. government and mortgage-backed securities. However, during the summer months, the atmosphere grew more optimistic. When it became apparent that most investors anticipated stronger growth and, therefore, higher interest rates, demand for these securities dropped off dramatically as investors re-entered the equity market. In addition, the U.S. dollar weakened, leading to curtailed demand from overseas investors. During the second half of the fiscal year, another development further weakened prospects for U.S. government securities. Although the U.S. government had been buying back Treasury securities with the surplus it had enjoyed for a few years, it now started to issue more Treasuries in order to finance deficit spending. This increased supply coincided with the marked drop-off in demand, resulting in a bond market characterized by rapidly rising interest rates and sharply falling bond prices. In a short and dramatic reversal, yields on Treasury securities fell to historically low levels in June, only to rise sharply through the end of August. In September, conditions stabilized somewhat, and yields leveled off or fell somewhat thereafter. Against this backdrop, mortgage-backed securities lagged Treasuries over the fiscal year. Earlier on, as interest rates were on the decline, mortgage-backed securities suffered somewhat from prepayment risk -- the risk that homeowners will refinance their mortgages, leaving principal repayments that must be reinvested at lower rates. When rates began to climb, prepayment risk dissipated. However, when interest rates rise, another type of risk comes into play. This so-called extension risk means that holders of these securities are unable to take advantage of the current higher rates because their investments are locked in at an older, lower rate. Thus, mortgage-backed securities can become increasingly vulnerable to sharp price declines as rates go up. - ------------------------------------------------------------------------------- MARKET SECTOR PERFORMANCE 12 MONTHS ENDED 9/30/03 - ------------------------------------------------------------------------------- Bonds - ------------------------------------------------------------------------------- Lehman GNMA Index (Government National Mortgage Association certificates) 3.25% - ------------------------------------------------------------------------------- Lehman Aggregate Bond Index (broad bond market) 5.41% - ------------------------------------------------------------------------------- Lehman Municipal Bond Index 3.90% - ------------------------------------------------------------------------------- CSFB High Yield Index 28.05% - ------------------------------------------------------------------------------- Equities - ------------------------------------------------------------------------------- S&P 500 Index (broad stock market) 24.40% - ------------------------------------------------------------------------------- Russell 1000 Growth Index (large-company growth stocks) 25.92% - ------------------------------------------------------------------------------- Russell 1000 Value Index (large-company value stocks) 24.37% - ------------------------------------------------------------------------------- These indexes provide an overview of performance in different market sectors for the 12 months ended 9/30/03. - ------------------------------------------------------------------------------- Strategy overview Coming into the fiscal year, we believed that positive returns would be dictated more by interest income than by significant capital appreciation. We felt that interest rates would rise, and therefore kept the portfolio's duration -- a measure of interest rate sensitivity -- relatively short through August in order to preserve capital. To achieve this, we invested a significant amount of the portfolio in Treasury securities and short-term money market investments that were less sensitive to changes in interest rates. In the mortgage-backed arena, we looked to underweight those securities that were more likely to be prepaid in a falling-rate environment, and sought to unearth value among lower-coupon Ginnie Maes, Fannie Maes, and Freddie Macs. We also focused on collateralized mortgage obligations (CMOs) that we believed provided appealing relative yields and little relative risk. When rates moved dramatically lower from March to June, we lowered the duration of the portfolio further, and invested the mortgage-backed portion in those securities we believed likely to be less affected by rising rates. To that end, we underweighted recently issued GNMAs and those with coupon rates significantly higher than those generally found in the market. Once interest rates started to rise, we sought to protect the portfolio from both the negative effects of rising interest rates and increased extension risk in the mortgage market. When the yield on the 10-year Treasury note rose to 4.25% at the end of August, we moved the portfolio to a less defensive positioning. While we adjusted this somewhat as the market rallied in September, we remained committed to deriving returns primarily from the income provided by portfolio holdings. As a result, the end of the fiscal year found your fund heavily invested in mortgage-backed securities, with little to no investments in Treasury securities or short-term cash equivalents. [GRAPHIC OMITTED: horizontal bar chart THE FUND'S MATURITY AND DURATION COMPARED] THE FUND'S MATURITY AND DURATION COMPARED 3/31/03 9/30/03 Average effective maturity in years 1.6 3.4 Duration in years 1.1 1.9 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 over the six months ended 9/30/03. How sector allocations affected performance The period brought with it significant volatility, and thus numerous challenges. In the midst of such uncertainty, we sought to protect the fund's principal while at the same time looking to garner high current income. Our decision to insulate the fund against possible interest-rate increases dampened performance until rates started to rise significantly from June 13 through August 31. In that timeframe, a defensive duration proved helpful. During the first half of the fiscal year, our decision to bring the fund down from its target allocation of 100% mortgage-backed securities -- in order to position it defensively by investing in Treasury bills and other short-term cash equivalents -- also held back returns. This was the case because mortgage-backed securities performed better than Treasuries during that six-month period. Overall, while mortgage-backed securities offered solid absolute returns during the past 12 months, they did not perform as well as Treasuries. Mortgages tend to outperform during stable interest-rate environments, and the past year was anything but stable. Our move back into a high mortgage stake may have held us back a bit during the last six months of the period. However, being ready to handle the volatility that arose helped propel your fund to very strong relative performance during the third quarter of 2003. Within the portfolio's mortgage-backed allocation, we continued our focus on Ginnie Maes (issued by the Government National Mortgage Association), your fund's traditional investments. However, as of late January, an investment policy change enabled us to invest in Freddie Macs (issued by the Federal Home Loan Mortgage Corporation) and Fannie Maes (issued by the Federal National Mortgage Association), two other types of mortgage-backed securities. These securities differ from Ginnie Maes in that they are backed only by the credit of the issuing government agency. Ginnie Maes, on the other hand, are backed by the full faith and credit of the U.S. government. Segments of the mortgage market that we currently favor include 30-year Ginnie Maes and 30-year Fannie Maes with 6.5% coupons. We chose investments within these sectors by issuer or coupon rate by analyzing relative valuation and yields. [GRAPHIC OMITTED: horizontal bar chart PORTFOLIO COMPOSITION AS OF 9/30/03] PORTFOLIO COMPOSITION AS OF 9/30/03 Collateralized mortgage obligations 8.4% Short-term investments 12.2% Fannie Mae 19.4% U.S. government and agency obligations Ginnie Mae 68.6% Freddie Mac 1.4% Footnote reads: Weightings are shown as a percentage of net asset value. Holdings will vary over time. A portion of short-term investments reflect amounts used to settle TBA purchase commitments. Another investment that proved particularly useful during the fiscal year was a type of collateralized mortgage obligation (CMO) known as interest-only strips. Issued by the Federal Home Loan Mortgage Corporation, Government National Mortgage Association, or private issuers, CMOs are high-quality investments that typically offer slightly lower yields than conventional mortgage-backed securities but provide a more stable stream of income. Payment sources from these securities are limited to the interest paid on mortgages, a characteristic that enabled us to use them as a hedge against rising rates and extension risk. Please note that all holdings discussed in this report are subject to review in accordance with the fund's investment strategy and may vary in the future. OF SPECIAL INTEREST Falling interest rates through much of the fiscal year made it necessary to decrease the fund's dividend. The fund's dividend for class A shares was lowered from $0.040 to $0.033 per share in January 2003; from $0.033 to $0.027 per share in March 2003; and from $0.027 to $0.018 per share in July 2003. Other share classes experienced similar reductions. On January 21, 2003, the fund's investment policies were modified to allow investments in mortgage-backed securities issued by Fannie Mae and Freddie Mac. Mortgage securities issued by these two agencies account for 78% of the mortgage-backed universe. These changes will allow the fund to take fuller advantage of fixed-income opportunities, particularly in the mortgage-backed area. The fund's management team The fund is managed by the Putnam Core Fixed-Income Team. The members of the team are Kevin Cronin (Portfolio Leader), Rob Bloemker (Portfolio Member), Carl Bell, Andrea Burke, Steve Horner, D. William Kohli, Michael Salm, John Van Tassel, and David Waldman. The outlook for your fund The following commentary reflects anticipated developments that could affect your fund over the next six months, as well as your management team's plans for responding to them. We expect the economy to continue to grow and believe that the pace of that growth is likely to quicken. Up to this point, this recovery has been a consumer-led one. We, along with the rest of the market, will be looking closely to see if businesses will help stimulate growth by increasing capital spending. Investors will likely look very closely at the employment market for signs of improvement. Economies abroad -- particularly in Asia -- are currently growing at a faster-than-anticipated pace. This improvement could prove to be helpful to the U.S. economy as well. Headwinds that the economy currently faces include a high current account deficit, diminished consumer confidence, and the impact of a weaker dollar. We do not expect interest rates to decline or rise dramatically. Therefore, we believe that returns in the bond market during the next 6 to 12 months will largely be driven by interest income rather than capital appreciation or depreciation. As a result, we have worked to maximize the current income of the fund by investing in the types of securities that yield the most within the fund's investment universe, namely mortgage-backed securities. Our stance currently is neither defensive nor aggressive, but neutral. We will continue to seek opportunities based on our analysis of relative valuation and yields. The views expressed in this report are exclusively those of Putnam Management. They are not meant as investment advice. Mutual funds that invest in these government securities are not guaranteed. Mortgage-backed securities are subject to prepayment risk. Performance summary This section provides information about your fund's performance during its fiscal year, which ended September 30, 2003.

Terms and definitions Total return shows how the value of the fund's shares changed over time, assuming you held the shares through the entire period and reinvested all distributions in the fund. Net asset value (NAV) is the price, or value, of one share of a mutual fund, without a sales charge. NAVs fluctuate with market conditions. The NAV is calculated by dividing the net value of all the fund's assets by the number of outstanding shares. Public offering price (POP) is the price of a mutual fund share plus the maximum sales charge levied at the time of purchase. POP performance figures shown here assume the 4.75% maximum sales charge for class A shares and 3.25% for class M shares. Contingent deferred sales charge (CDSC) is a charge applied at the time of the redemption of class B 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 charges or CDSC and are available only to certain defined contribution plans.

A guide to the financial statements These sections of the report, as well as the accompanying Notes, preceded by the Independent Auditors' Report, constitute the fund's financial statements. The fund's portfolio lists all the fund's investments and their values as of the last day of the reporting period. Holdings are organized by asset type and industry sector, country, or state to show areas of concentration and diversification. Statement of assets and liabilities shows how the fund's net assets and share price are determined. All investment and noninvestment assets are added together. Any unpaid expenses and other liabilities are subtracted from this total. The result is divided by the number of shares to determine the net asset value per share, which is calculated separately for each class of shares. (For funds with preferred shares, the amount subtracted from total assets includes the net assets allocated to remarketed preferred shares.) Statement of operations shows the fund's net investment gain or loss. This is done by first adding up all the fund's earnings -- from dividends and interest income -- and subtracting its operating expenses to determine net investment income (or loss). Then, any net gain or loss the fund realized on the sales of its holdings -- as well as any unrealized gains or losses over the period -- is added to or subtracted from the net investment result to determine the fund's net gain or loss for the fiscal year. Statement of changes in net assets shows how the fund's net assets were affected by distributions to shareholders and by changes in the number of the fund's shares. It lists distributions and their sources (net investment income or realized capital gains) over the current reporting period and the most recent fiscal year-end. The distributions listed here may not match the sources listed in the Statement of operations because the distributions are determined on a tax basis and may be paid in a different period from the one in which they were earned. Financial highlights provide an overview of the fund's investment results, per-share distributions, expense ratios, net investment income ratios, and portfolio turnover in one summary table, reflecting the five most recent reporting periods. In a semiannual report, the highlight table also includes the current reporting period. For open-end funds, a separate table is provided for each share class. Independent auditors' report The Board of Trustees and Shareholders Putnam U.S. Government Income Trust: We have audited the accompanying statement of assets and liabilities of Putnam U.S. Government Income Trust, including the fund's portfolio, as of September 30, 2003, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the four years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform our audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of September 30, 2003 by correspondence with the custodian and brokers or by other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.

The accompanying notes are an integral part of these financial statements. Notes to financial statements September 30, 2003 Note 1 Significant accounting policies Putnam U.S. Government Income Trust (the "fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The fund's investment objective is to seek as high a level of current income as is consistent with preservation of capital by investing mainly in securities which have short to long-term maturities and are backed by the full faith and credit of the United States. The fund also invests in repurchase agreements and forward commitments relating to those investments. 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 January 21, 2003. Class A shares are sold with a maximum front-end sales charge of 4.75%. Class B shares, which convert to class A shares after approximately eight years, do not pay a front-end sales charge but pay a higher ongoing distribution fee than class A, class M and class R shares, and are subject to a contingent deferred sales charge, if those shares are redeemed within six years of purchase. Class C shares are subject to the same fees and expenses as class B shares, except that class C shares have a one-year 1.00% contingent deferred sales charge and do not convert to class A shares. Class M shares are sold with a maximum front end sales charge of 3.25% and pay an ongoing distribution fee that is higher than class A and class R shares but lower than class B and class C shares. Class R shares are sold without a front end sales charge and pay an ongoing distribution fee that is higher than class A 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. Expenses of the fund are borne pro-rata by the holders of each class of shares, except that each class bears expenses unique to that class (including the distribution fees applicable to such class). Each class votes as a class only with respect to its own distribution plan or other matters on which a class vote is required by law or determined by the Trustees. Shares of each class would receive their pro-rata share of the net assets of the fund, if the fund were liquidated. In addition, the Trustees declare separate dividends on each class of shares. The following is a summary of significant accounting policies consistently followed by the fund in the preparation of its financial statements. The preparation of financial statements is in conformity with accounting principles generally accepted in the United States of America and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. A) Security valuation Investments, including mortgage backed securities, are valued on the basis of valuations provided by an independent pricing service, approved by the Trustees. Such service providers use information with respect to transactions in bonds, quotations from bond dealers, market transactions in comparable securities and various relationships between securities in determining value. Restricted securities are valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees. Short-term investments having remaining maturities of 60 days or less are valued at amortized cost, which approximates fair value. B) Joint trading account The fund may transfer uninvested cash balances, including cash collateral received under security lending arrangements, into a joint trading account along with the cash of other registered investment companies and certain other accounts managed by Putnam Investment Management, LLC ("Putnam Management"), the fund's manager, an indirect wholly-owned subsidiary of Putnam, LLC. These balances may be invested in issuers of high-grade short-term investments having maturities of up to 397 days for collateral received under security lending arrangements and up to 90 days for other cash investments. C) Repurchase agreements The fund, or any joint trading account, through its custodian, receives delivery of the underlying securities, the market value of which at the time of purchase is required to be in an amount at least equal to the resale price, including accrued interest. Collateral for certain tri-party repurchase agreements is held at the counterparty's custodian in a segregated account for the benefit of the fund and the counterparty. Putnam Management is responsible for determining that the value of these underlying securities is at all times at least equal to the resale price, including accrued interest. D) Security transactions and related investment income Security transactions are recorded on the trade date (date the order to buy or sell is executed). Gains or losses on securities sold are determined on the identified cost basis. Interest income is recorded on the accrual basis. All premiums/discounts are amortized/accreted on a yield-to-maturity basis. E) TBA purchase commitments The fund may enter into "TBA" (to be announced) commitments to purchase securities for a fixed unit price at a future date beyond customary settlement time. Although the unit price has been established, the principal value has not been finalized. However, the amount of the commitments will not significantly differ from the principal amount. The fund holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the fund may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date, which risk is in addition to the risk of decline in the value of the fund's other assets. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities, according to the procedures described under "Security valuation" above. Although the fund will generally enter into TBA purchase commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the fund may dispose of a commitment prior to settlement if Putnam Management deems it appropriate to do so. F) TBA sale commitments The fund may enter into TBA sale commitments to hedge its portfolio positions or to sell mortgage-backed securities it owns under delayed delivery arrangements. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, equivalent deliverable securities, or an offsetting TBA purchase commitment deliverable on or before the sale commitment date, are held as "cover" for the transaction. Unsettled TBA sale commitments are valued at the current market value of the underlying securities, generally according to the procedures described under "Security valuation" above. The contract is "marked-to-market" daily and the change in market value is recorded by the fund as an unrealized gain or loss. If the TBA sale commitment is closed through the acquisition of an offsetting purchase commitment, the fund realizes a gain or loss. If the fund delivers securities under the commitment, the fund realizes a gain or a loss from the sale of the securities based upon the unit price established at the date the commitment was entered into. TBA sale commitments outstanding at period end are listed after The fund's portfolio. G) Federal taxes It is the policy of the fund to distribute all of its taxable income within the prescribed time and otherwise comply with the provisions of the Internal Revenue Code applicable to regulated investment companies. It is also the intention of the fund to distribute an amount sufficient to avoid imposition of any excise tax under Section 4982 of the Internal Revenue Code of 1986, as amended. Therefore, no provision has been made for federal taxes on income, capital gains or unrealized appreciation on securities held nor for excise tax on income and capital gains. At September 30, 2003, the fund had a capital loss carryover of $115,552,142 available to the extent allowed by tax law to offset future capital gains, if any. The amount of the carryover and the expiration dates are: Loss Carryover Expiration - ---------------------------------- $51,883,929 September 30, 2004 8,892,718 September 30, 2005 23,731,356 September 30, 2008 31,044,139 September 30, 2009 H) Distributions to shareholders Distributions to shareholders from net investment income are recorded by the fund on the ex-dividend date. Distributions from capital gains, if any, are recorded on the ex-dividend date and paid at least annually. The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. These differences include temporary and permanent differences of losses on wash sale transactions and the expiration of a capital loss carryover. 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. For the year ended September 30, 2003, the fund reclassified $18,174,717 to increase undistributed net investment income and $178,265,538 to decrease paid-in-capital, with a decrease to accumulated net realized losses of $160,090,821. The tax basis components of distributable earnings and the federal tax cost as of period end were as follows: Unrealized appreciation $53,810,240 Unrealized depreciation (3,472,520) ------------ Net unrealized appreciation 50,337,720 Capital loss carryforward (115,552,142) Cost for federal income tax purposes $3,103,452,950 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: 0.57% of the first $500 million of average net assets, 0.475% of the next $500 million, 0.4275% of the next $500 million and 0.38% thereafter. The fund reimburses Putnam Management an allocated amount for the compensation and related expenses of certain officers of the fund and their staff who provide administrative services to the fund. The aggregate amount of all such reimbursements is determined annually by the Trustees. Custodial functions for the fund's assets are provided by Putnam Fiduciary Trust Company (PFTC), a subsidiary of Putnam, LLC. Investor servicing agent functions are provided by Putnam Investor Services, a division of PFTC. The fund has entered into an arrangement with PFTC whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the fund's expenses. For the year ended September 30, 2003, the fund's expenses were reduced by $303,880 under these arrangements. Each independent Trustee of the fund receives an annual Trustee fee, of which $3,362 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 by it in distributing shares of the fund. The Plans provide for payments by the fund to Putnam Retail Management at an annual rate 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 year ended September 30, 2003, Putnam Retail Management, acting as underwriter, received net commissions of $229,261 and $40,234 from the sale of class A and class M shares, respectively, and received $1,620,999 and $30,856 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 year ended September 30, 2003, Putnam Retail Management, acting as underwriter, received $62,429and no monies on class A and class M redemptions, respectively. Note 3 Purchases and sales of securities During the year ended September 30, 2003, cost of purchases and proceeds from sales of U.S. government and agency obligations other than short-term investments aggregated $8,065,412,911 and $7,949,954,822, respectively.

Note 5 Regulatory matters and litigation On November 13, 2003, Putnam Management agreed to entry of an order by the Securities and Exchange Commission in partial resolution of administrative and cease-and-desist proceedings initiated by the SEC on October 28, 2003 in connection with alleged excessive short-term trading by certain investment professionals. Under the order, Putnam Management will make restitution for losses attributable to excessive short-term trading by Putnam employees, institute new employee trading restrictions and enhanced employee trading compliance, retain an independent compliance consultant, and take other remedial actions. Putnam Management neither admitted nor denied the order's findings that it willfully violated provisions of the securities laws. A civil monetary penalty and other monetary relief, if any, will be determined at a later date. Putnam Management, and not the investors in any Putnam fund, will bear all costs, including restitution, civil penalties and associated legal fees. Administrative proceedings initiated by the Commonwealth of Massachusetts on October 28, 2003 against Putnam Management in connection with alleged market timing activities by Putnam employees and by participants in some Putnam-administered 401(k) plans are pending. The SEC's and Commonwealth's allegations also serve as the general basis for numerous lawsuits, including purported class action lawsuits, filed against Putnam Management and certain related parties, including certain open-end Putnam funds. Putnam Management has agreed to bear any reasonable legal costs incurred by the Putnam funds in connection with defending these lawsuits. Based on currently available information, Putnam Management believes that the likelihood that the pending actions will have a material adverse financial impact on the fund is remote, and that the pending actions are not likely to materially affect its ability to provide investment management services to its clients, including the Putnam funds. Review of these matters by counsel for Putnam Management and by separate independent counsel for the Putnam funds and their independent Trustees is continuing. In addition, Marsh & McLennan Companies, Inc., Putnam Management's parent company, has engaged counsel to conduct a separate review of Putnam Management's trading policies and controls. Putnam Management has committed to make complete restitution for any losses suffered by Putnam shareholders as a result of any improper market-timing activities by Putnam employees or within Putnam-administered 401(k) plans. - ---------------------------------------------------------------------- Federal tax information (Unaudited) The Form 1099 you receive in January 2004 will show the tax status of all distributions paid to your account in calendar 2003.

Class Y shares are offered exclusively to clients that meet the eligibility requirements specified in the fund's prospectus for such shares. Performance of class Y shares, which incur neither a front-end load, distribution fee, nor contingent deferred sales charge, will differ from performance of class A, B, C, M, and R shares, which are discussed more extensively in the annual report.

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.
