Putnam Ohio Tax Exempt Income Fund 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 5-31-03 [GRAPHIC OMITTED: SILVER PITCHER] [SCALE LOGO OMITTED] FROM THE TRUSTEES [GRAPHIC OMITTED: PHOTO OF JOHN A. HILL AND GEORGE PUTNAM III] Dear Fellow Shareholder: We are pleased to report positive results for Putnam Ohio Tax Exempt Income Fund for the fiscal year ended May 31, 2003. While your fund underperformed its benchmark during the period, at net asset value it performed in line with its Lipper fund category average. Details of these results can be found on page 8. As you will see in the accompanying report from the fund's management team, an emphasis on noncallable bonds and bonds with longer maturities was a positive contributor to performance during the period. On the other hand, the fund's allocation to higher-yielding lower-rated issues detracted slightly from performance results. The managers also discuss in detail the strategies they employed during the period and offer their views of prospects for the fiscal year that has just begun. Meanwhile, we would like you to know how much we appreciate your continued confidence in Putnam. No one can say for certain, of course, how long the current market uncertainties will last, but the management team will continue to devote its full attention to maintaining the fund's fine long-term record. Respectfully yours, /S/ JOHN A. HILL /S/ GEORGE PUTNAM, III John A. Hill George Putnam, III Chairman of the Trustees President of the Funds July 16, 2003 REPORT FROM FUND MANAGEMENT FUND HIGHLIGHTS * Putnam Ohio Tax Exempt Income Fund's class A shares posted total returns of 9.48% at net asset value and 4.30% at public offering price for the fiscal year ended May 31, 2003. * Due to the differences in portfolio quality and composition, the fund underperformed its benchmark, the Lehman Municipal Bond Index, which returned 10.36% for the 12-month period ended May 31. * The fund's performance at net asset value was in line with the average return for its Lipper category, Ohio Municipal Debt Funds, which was 9.19%. * See the Performance Summary on page 8 for complete fund performance, comparative performance, and Lipper data. * PERFORMANCE COMMENTARY The fund's results should be considered in the context of a generally favorable interest-rate environment. Investments in longer-maturity and noncallable bonds performed well. Investments in insured and high-quality bonds also proved to be an asset, given investors' conservative leanings and preference for relatively secure investments. The fund's lower-rated holdings, which contribute to the portfolio's monthly income, underperformed in the difficult economic environment. The presence of these bonds helps explain the fund's slight underperformance relative to its benchmark, which is comprised primarily of high-quality tax-exempt bonds from around the nation. We believe the markets are beginning to factor in the potential for a return of higher interest rates. Recently, we've been positioning the fund to limit the price depreciation that typically accompanies a rising-rate market. These defensive measures are prudent in our estimation, given the historically low interest rates we've seen for the past few months. Fund Profile Putnam Ohio Tax Exempt Income Fund seeks to provide high current income free from federal income tax and Ohio state personal income taxes, as we believe to be consistent with the preservation of capital. It may be suitable for Ohio investors seeking tax-free income through a diversified portfolio of municipal bonds issued in Ohio. * MARKET OVERVIEW The first half of the fiscal year was generally positive for the municipal bond market. In an environment marked by earnings disappointments, economic weakness, and numerous allegations of corporate malfeasance, investors sought the relative safety of high-quality bonds. Increased demand for bonds pushed their prices higher, and many of your fund's holdings benefited. In the second half of the fiscal year, several factors tempered municipal bond performance, including significant declines in tax revenues and subsequent downgrades in municipalities' credit quality. United Airlines, which had provided credit backing for several municipal-bond issues, filed for bankruptcy, as had US Airways in the months before. In late April, American Airlines narrowly avoided a similar fate. Various segments of the electric power sector were under duress as well. These difficulties put pressure on industrial development bonds (IDBs), which are issued by municipalities but backed by companies benefiting from the financing. Lastly, over $357 billion in municipal bonds was issued in 2002 -- an all-time record. In 2003, supply continued to swell and is on track to exceed the previous year's record. These factors had a dampening effect on municipal bond prices.

Duration is an investment term for measuring this interest-rate sensitivity and can be calculated from bond coupon rates and maturities. During the summer of 2002, we began implementing a defensive strategy (shorter duration, less sensitivity) in anticipation of rising interest rates. When interest rates rose in October, we returned to a more neutral duration as the outlook for growth in the economy was less clear. However, this positioning still limited upside potential when the market rallied in May. As the period ended, we believed interest rates were unsustainably low and began to shift the portfolio back toward a more defensive position. In early calendar 2003, when tax-exempt municipal bonds offered investors almost the same yield as comparable Treasury bonds, we established a cross-market arbitrage position, in which we bought intermediate-term municipal bonds and shorted 10-year Treasury futures contracts. Our thesis was that if interest rates should rise (causing bond prices to fall), the fund would have a loss on the bonds, and yet, potential gains on the futures contracts would more than compensate for the loss. On the other hand, if rates should fall (causing bond prices to rise), a loss on the futures contracts would be mitigated by a gain on the bonds. We have seen the latter scenario begin to develop as municipal bonds appreciated during the second half of the period. [GRAPHIC OMITTED: vertical bar chart THE FUND'S MATURITY AND DURATION COMPARED] THE FUND'S MATURITY AND DURATION COMPARED* 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). as of as of 11/30/2002 5/31/2003 Average effective maturity in years 10.3 8.6 Duration in years 6.6 5.7 Footnote reads: *Average effective maturity also takes into account put and call features, where applicable, and reflects prepayments for mortgage-backed securities. * HOW FUND HOLDINGS AND ALLOCATIONS AFFECTED PERFORMANCE Although primarily an investment-grade fund, your portfolio maintained its exposure to higher-yielding securities to pursue a higher return through the income and appreciation potential we believed they were offering. With so much uncertainty about economic growth and the direction of interest rates clouding the fiscal year, we took steps to broaden the fund's exposure across and within the various sectors that make up the portfolio. We believe a well-diversified cross section of holdings is one of the best strategies for reducing risk and protecting the portfolio against negative or unforeseen events. For example, during the fiscal period we thought that the combined weightings of Ohio Edison and Cleveland Electric, two of the fund's electric power holdings from the same issuer -- the Ohio State Air Quality Development Authority -- constituted too great a concentration of assets in a single issuer. Consequently, we sold the Cleveland Electric position, which had the shorter maturity of the two holdings, and reinvested the proceeds from the sale in two new holdings outside the electric power sector. Two-thirds of the proceeds from this sale were invested in Ohio State Higher Educations Facility bonds issued for Kenyon College. These mandatory put bonds, which carry a coupon of 5.05% and mature on 7/1/37 are rated A2 and A by Moody's and Standard & Poor's, respectively. With mandatory put bonds, the issuer will redeem the bonds at par, or face value, at a stated time before maturity -- in this case 7/1/16. We think the education sector is relatively stable, rarely experiences defaults and can offer above-average yields. These put bonds are financing improvements to an athletic facility and are backed by strong fundamentals, including a solid endowment, strong alumni support, and high student applications. Most of the balance of the utility sale proceeds were invested in A-rated Cuyahoga County bonds issued for the Cleveland Clinic Health System. We've seen a large supply of uninsured investment-grade hospital bonds coming to market in recent months, improving the number and quality of prospects for your portfolio. In addition to refinancing older, more expensive debt at today's historically low interest rates, hospitals in high-growth locations are requiring more resources to finance their expansion to meet increasing patient demand. The Cleveland Clinic, which serves northeast Ohio and southwest Florida, has a medical and educational reputation on par with Johns Hopkins and the Mayo Clinic. While the Clinic previously incurred investment losses, we believe the steady, high-quality delivery of its core health services in its target markets should eventually restore much of its diminished cash flow. We believe the fund's diversification also helped soften the effects of a price decline in its investment in Cleveland Ohio Airport Authority Revenue bonds, which are backed by Continental Airlines. The airline industry as a whole has been caught in a headwind of negative events that started when the terrorist attacks of September 11, 2001, sharply reduced airline travel. The sluggish economy that followed further reduced business travel, while high jet-fuel prices increased costs. Finally, the war in Iraq and (most recently) concern about SARS further hampered the industry's efforts to recover. However, the recent labor/management negotiations that enabled American Airlines to stay in business, at least for a time, is renewing our interest in this sector, which seems overdue for a turnaround. [GRAPHIC OMITTED: pie chart CREDIT QUALITY OVERVIEW] CREDIT QUALITY OVERVIEW* Aaa/AAA -- 47.3% Aa/AA -- 16.0% A -- 15.3% Baa/BBB -- 15.7% Ba/BB -- 3.1% B and lower -- 0.4% Other (VMIG1) -- 2.2% Footnote reads: * As a percentage of market value as of 5/31/03. A bond rated Baa/BBB or higher is considered investment grade. All ratings reflect Moody's and Standard and Poor's descriptions unless noted otherwise; percentages may include unrated bonds considered by Putnam Management to be of comparable quality. Ratings will vary over time. Many states across the country have been driven into historically high deficit positions over the past year. The slowing economy, along with weakness in the stock market, higher Medicaid costs, a sharp reduction in capital gain tax revenues and slower personal, sales and corporate income tax collections, have contributed to this trend. This makes general obligation (GO) bonds especially vulnerable to credit downgrades, since they are financed by the tax revenues raised by state and local governments. Several states have already seen their credit downgraded by the rating agencies. While the downgrade risk for Ohio is high, especially given the fact that it has been on a negative credit watch since August 2002, the state's ratings by the three major rating agencies held steady throughout the fiscal year. Credit quality remains a critical determinant in our selection process, and we're following the situation closely but still feel confident that the issuers of the GOs held by the fund will meet their debt obligations. Tobacco settlement bonds are issued by municipalities and secured by cash payments made in satisfaction of legal judgments against the tobacco industry. Since they are subject to special risks, they generally offer higher yields than other bonds of comparable quality. Among the special risks of investing in tobacco settlement bonds is the possibility that interest payments could be affected by further litigation against the tobacco industry. Furthermore, if the supply of tobacco settlement bonds exceeds demand, the value of the bonds could drop. We have always approached these bonds with caution, and feel comfortable that the fund's two holdings, which constitute less than 1% of total assets, are making a valuable contribution to the portfolio's income stream and diversification. Please note that all holdings discussed in this report are subject to review in accordance with the fund's investment strategy and may vary in the future. * THE FUND'S MANAGEMENT TEAM The fund is managed by the Putnam Tax Exempt Fixed-Income Team. The members of the team are Susan McCormack (Portfolio Leader), Paul Drury (Portfolio Member), David Hamlin (Portfolio Member), Richard Wyke (Portfolio Member), Joyce Dragone, and Jerome Jacobs. 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. Our current outlook for the municipal bond market is cautiously optimistic. The conflict with Iraq is largely over, and investors are focused on economic concerns on the home front. While serious issues remain, the level of uncertainty in the world seems to have eased a bit, though we expect continued volatility. Further, we expect that market yields will move higher in the near term as a weakening dollar, Federal Reserve Board policy, the recently enacted tax cut package, and growing federal budget deficits take effect. Municipal budgets will continue to face significant pressures in the months ahead. Governments will wrangle with how to implement costly home-front protection measures while at the same time pushing tax cuts to stimulate economic growth. Historically, improvement in the credit quality of state and local governments has lagged a general economic recovery, so we expect municipal credit quality to remain fragile for some time to come. Over the next few months, the ratio of municipal bond yields to comparable Treasury yields is likely to return to more normal levels. Accordingly, we will look for opportunities to reduce our cross-market arbitrage position (by selling municipal bonds and buying back the Treasury futures contracts) and we expect the fund will profit from the transactions. In our opinion, the market continues to offer attractive value and compelling risk/reward characteristics. With credit spreads remaining very generous, we believe credit risk is worth taking in moderate amounts. We believe municipal bonds could perform well relative to other fixed-income sectors, because demand for the bonds is firm and we expect supply should moderate as rates move higher. We believe we have positioned your fund to take advantage of the market's potential. The views expressed in this report are exclusively those of Putnam Management. They are not meant as investment advice. This fund concentrates its investments in one state and involves more risk than a fund that invests more broadly.

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 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. 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 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).

It is our policy to protect the confidentiality of your information, whether or not you currently own shares of our funds, and in particular, not to sell information about you or your accounts to outside marketing firms. We have safeguards in place designed to prevent unauthorized access to our computer systems and procedures to protect personal information from unauthorized use. Under certain circumstances, we share this information with outside vendors who provide services to us, such as mailing and proxy solicitation. In those cases, the service providers enter into confidentiality agreements with us, and we provide only the information necessary to process transactions and perform other services related to your account. We may also share this information with our Putnam affiliates to service your account or provide you with information about other Putnam products or services. It is also our policy to share account information with your financial advisor, if you've listed one on your Putnam account.

A GUIDE TO THE FINANCIAL STATEMENTS These sections of the report, as well as the accompanying Notes, preceded by the Report of independent accountants, 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. REPORT OF INDEPENDENT ACCOUNTANTS To the Trustees and Shareholders of Putnam Ohio Tax Exempt Income Fund In our opinion, the accompanying statement of assets and liabilities, including the fund's portfolio (except for bond ratings) and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Putnam Ohio Tax Exempt Income Fund (the "fund") at May 31, 2003, and the results of its operations, the changes in its net assets and the financial highlights for the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of investments owned at May 31, 2003, by correspondence with the custodian, provide a reasonable basis for our opinion.

The accompanying notes are an integral part of these financial statements. NOTES TO FINANCIAL STATEMENTS May 31, 2003 Note 1 Significant accounting policies Putnam Ohio Tax Exempt Income Fund (the "fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The fund seeks as high a level of current income exempt from federal income tax and Ohio personal income tax as Putnam Investment Management, LLC ("Putnam Management"), the fund's manager, an indirect wholly-owned subsidiary of Putnam, LLC, believes is consistent with preservation of capital by investing primarily in a portfolio of investment-grade Ohio tax-exempt securities with intermediate- to long-term maturities. The fund offers class A, class B and class M shares. 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 and class M shares, and are subject to a contingent deferred sales charge, if those shares are redeemed within six years of purchase. 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 but lower than class B shares. 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 fund may be affected by economic and political developments in the state of Ohio. 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 Tax-exempt bonds and notes are valued on the basis of valuations provided by an independent pricing service, approved by the Trustees. Such services 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. B) 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. The premium in excess of the call price, if any, is amortized to the call date; thereafter, any remaining premium is amortized to maturity. C) Futures and options contracts The fund may use futures and options contracts to hedge against changes in the values of securities the fund owns or expects to purchase. The fund may also write options on securities it owns or in which it may invest to increase its current returns. The potential risk to the fund is that the change in value of futures and options contracts may not correspond to the change in value of the hedged instruments. In addition, losses may arise from changes in the value of the underlying instruments, if there is an illiquid secondary market for the contracts, or if the counterparty to the contract is unable to perform. When the contract is closed, the fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Realized gains and losses on purchased options are included in realized gains and losses on investment securities. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. The fund and the broker agree to exchange an amount of cash equal to the daily fluctuation in the value of the futures contract. Such receipts or payments are known as "variation margin." Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by dealers. Futures and written option contracts outstanding at period end are listed after The fund's portfolio. D) Line of credit The fund has entered into a committed line of credit with certain banks. This line of credit agreement includes restrictions that the fund maintain an asset coverage ratio of at least 300% and that borrowings not exceed prospectus limitations. For the year ended May 31, 2003, the fund had no borrowings against the line of credit. E) Federal taxes It is the policy of the fund to distribute all of its 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 May 31, 2003, the fund had a capital loss carryover of approximately $4,308,000 available to the extent allowed by tax law to offset future net capital gains, if any. The amount of the carryover and the expiration dates are: Loss Carryover Expiration - -------------- ------------------ $3,948,000 May 31, 2009 360,000 May 31, 2010 F) Distributions to shareholders Income dividends are recorded daily by the fund and are paid monthly. Distributions from capital gains, if any, are recorded on the ex-dividend date and paid at least annually. The amount and character of income and gains to be distributed are determined in accordance with income tax regulations which may differ from generally accepted accounting principles. These differences include temporary and permanent differences of dividends payable, realized and unrealized gains and losses on certain futures contracts, market discount and straddle loss deferrals. 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 May 31, 2003, the fund reclassified $164,890 to decrease distributions in excess of net investment income, with an increase to accumulated net realized losses of $164,890. The tax basis components of distributable earnings and the federal tax cost as of period end were as follows: Unrealized appreciation $20,187,881 Unrealized depreciation (1,527,314) ------------- Net unrealized appreciation 18,660,567 Undistributed tax-exempt income 326,689 Undistributed ordinary income 145,833 Capital loss carryforward (4,308,173) Post-October loss -- Cost for federal income tax purposes $209,153,137 Note 2 Management fee, administrative services and other transactions Putnam Management is paid for management and investment advisory services quarterly based on the average net assets of the fund. Such fee is based on the lesser of (i) an annual rate of 0.50% of the average net assets of the fund or (ii) the following annual rates expressed as a percentage of the fund's average net assets: 0.60% of the first $500 million, 0.50% of the next $500 million, 0.45% of the next $500 million, 0.40% of the next $5 billion, 0.375% of the next $5 billion, 0.355% of the next $5 billion, 0.34% of the next $5 billion and 0.33% thereafter. The fund reimburses Putnam Management an allocated amount for the compensation and related expenses of certain officers of the fund and their staff who provide administrative services to the fund. The aggregate amount of all such reimbursements is determined annually by the Trustees. Custodial functions for the fund's assets are provided by Putnam Fiduciary Trust Company (PFTC), a subsidiary of Putnam, LLC. Investor servicing agent functions are provided by Putnam Investor Services, a division of PFTC. The fund has entered into an arrangement with PFTC whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the fund's expenses. For the year ended May 31, 2003, the fund's expenses were reduced by $41,082 under these arrangements. Each independent Trustee of the fund receives an annual Trustee fee, of which $646 has been allocated to the fund, and an additional fee for each Trustees meeting attended. Trustees receive additional fees for attendance at certain committee meetings. The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan") which allows the Trustees to defer the receipt of all or a portion of Trustees fees payable on or after July 1, 1995. The deferred fees remain invested in certain Putnam funds until distribution in accordance with the Deferral Plan. The fund has adopted an unfunded noncontributory defined benefit pension plan (the "Pension Plan") covering all Trustees of the fund who have served as a Trustee for at least five years. Benefits under the Pension Plan are equal to 50% of the Trustee's average total retainer and meeting fees for the three years preceding retirement. Pension expense for the fund is included in Compensation of Trustees in the Statement of operations. Accrued pension liability is included in Payable for compensation of Trustees in the Statement of assets and liabilities. The fund has adopted distribution plans (the "Plans") with respect to its class A, class B and class M shares pursuant to rule 12b-1 under the Investment Company Act of 1940. The purpose of the Plans is to compensate Putnam Retail Management, a wholly-owned subsidiary of Putnam, LLC and Putnam Retail Management GP, Inc., for services provided and expenses incurred by it in distributing shares of the fund. The Plans provide for payments by the fund to Putnam Retail Management at an annual rate of up to 0.35%, 1.00% and 1.00% of the average net assets attributable to class A, class B and class M shares, respectively. The Trustees have approved payment by the fund at the annual rates of 0.20%, 0.85% and 0.50% of the average net assets attributable to class A, class B and class M shares, respectively. For the year ended May 31, 2003, Putnam Retail Management, acting as underwriter, received net commissions of $27,400 and $605 from the sale of class A and class M shares, respectively, and received $56,101 in contingent deferred sales charges from redemptions of class B shares. A deferred sales charge of up to 1.00% is assessed on certain redemptions of class A shares that were purchased without an initial sales charge as part of an investment of $1 million or more. For the year ended May 31, 2003, Putnam Retail Management, acting as underwriter, received $40 on class A redemptions. Note 3 Purchases and sales of securities During the year ended May 31, 2003, cost of purchases and proceeds from sales of investment securities other than short-term investments aggregated $57,253,911 and $52,006,706, respectively. There were no purchases and sales of U.S. government obligations. Note 4 Capital shares At May 31, 2003, there was an unlimited number of shares of beneficial interest authorized.
