Since 1937, our values have been rooted in a profound sense of responsibility for the money entrusted to us.

A prudent approach to investing

We use a research-driven team approach to seek consistent, dependable, superior investment results over time, although there is no guarantee a fund will meet its objectives.

THE PRUDENT MAN RULE

All that can be required of a trustee to invest is that he shall conduct himself faithfully and exercise a sound discretion. He is to observe how men of prudence, discretion, and intelligence manage their own affairs, not in regard to speculation, but in regard to the permanent disposition of their funds, considering the probable income, as well as the probable safety of the capital to be invested.

Message from the Trustees

Dear Fellow Shareholder:

Reflecting investor uncertainty about the outlook for the U.S. economy, volatility in the financial markets has been on the rise: after a downturn in March, the Dow Jones Industrial Average recently reached new record-high levels. However, it remains to be seen whether the current levels are sustainable. From our perspective, we are encouraged by recent indications of moderate inflation, a low unemployment rate, and a rebound in manufacturing. We consequently believe the resilience of the U.S. economy will enable it to weather this period of uncertainty.

As we communicated in proxy materials recently mailed to all Putnam fund shareholders, on February 1, 2007, Marsh & McLennan Companies, Inc. announced that it had signed a definitive agreement to sell its ownership interest in Putnam Investments Trust, the parent company of Putnam Management and its affiliates, to Great-West Lifeco Inc. Great-West Lifeco is a financial services holding company with operations in Canada, the United States, and Europe and is a member of the Power Financial Corporation group of companies. We are pleased to announce that in mid-May, shareholders voted overwhelmingly in favor of the proposed transaction. While it is still subject to regulatory approvals and other conditions, we currently expect the transaction to be completed in the middle of the year.

We would also like to take this opportunity to announce that Putnam President and Chief Executive Officer Ed Haldeman, one of your fund’s Trustees since 2004, has been named President of the Funds, assuming this role from George Putnam, III. This change will enable George Putnam to become an independent Trustee of the funds upon completion of the transaction with Great-West Lifeco. Both George and Ed will continue serving on the Board of Trustees in our collective role of overseeing the Putnam funds on your behalf.

In the following pages, members of your fund’s management team discuss the fund’s performance and strategies for the fiscal period ended April 30, 2007, and provide their outlook for the months ahead. As always, we thank you for your support of the Putnam funds.



Putnam Municipal Opportunities Trust: potential for high current
income exempt from federal income tax

One of the most significant challenges of fixed-income investing is taxes on income. Investing in municipal bonds through a fund such as Putnam Municipal Opportunities Trust can help address this challenge. While the stated yields on municipal bonds are usually lower than those of taxable bonds, the income most of these bonds pay has the advantage of being exempt from federal tax.

Municipal bonds are typically issued by states and local municipalities to raise funds for building and maintaining public facilities. The bonds are backed by either the issuing city or town, by revenues collected from usage fees, or by state tax revenues. Depending on the type of backing, the bonds will have varying degrees of credit risk, which is the risk that the issuer will not be able to repay the bond.

Many municipal bonds are not rated by independent rating agencies such as Standard & Poor’s and Moody’s.This is primarily because many issuers decide not to pursue a rating that might be below investment grade. As a result, investment managers must do additional research to determine whether these bonds are prudent investments.

Evaluating a bond’s credit risk is one area in which Putnam has particular expertise. Putnam’s municipal bond research team analyzes each issue in depth and assigns non-rated bonds an agency-equivalent Putnam rating. This analysis helps the team identify bonds with attractive risk/return profiles among the large number of bonds not rated by agencies.

Once the fund has invested in a bond, the fund’s management team continues to monitor developments that affect the overall bond market, the specific sector, and the issuer of the bond. Typically, higher-risk, lower-rated bonds are reviewed more frequently because of their greater potential risk.

The goal of the team’s research and active management is to stay a step ahead of the industry and pinpoint opportunities to adjust the fund’s holdings for the benefit of the fund and its shareholders.

Lower-rated bonds may offer higher yields in return for most risk. Capital gains, if any, are taxable for federal and, in most cases, state purposes. For some investors, investment income may be subject to the federal alternative minimum tax. Income from federally exempt funds may be subject to state and local taxes. Please consult with your tax advisor for more information. 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. The fund uses leverage, which involves risk and may increase the volatility of the fund’s net asset value. The fund’s shares trade on a stock exchange at market prices, which may be higher or lower than the fund’s net asset value.

How do closed-end funds
differ from open-end funds?

More assets at work While open-end funds need to maintain a cash position to meet redemptions, closed-end funds are not subject to redemptions and can keep more of their assets invested in the market.

Traded like stocks Closed-end fund shares are traded on stock exchanges, and their market prices fluctuate in response to supply and demand, among other factors.

Market price vs. net asset value Like an open-end fund’s net asset value (NAV) per share, the NAV of a closed-end fund share equals the current value of the fund’s assets, minus its liabilities, divided by the number of shares outstanding. However, when buying or selling closed-end fund shares, the price you pay or receive is the market price. Market price reflects current market supply and demand and may be higher or lower than the NAV.

Strategies for higher income Closed-end funds have greater flexibility to use strategies such as “leverage” — for example, issuing preferred shares to raise capital, then seeking to invest it at higher rates to enhance return for common shareholders.

Municipal bonds may finance a range of community projects
and thus play a key role in local development.



Putnam Municipal Opportunities Trust is a leveraged fund that seeks to provide as high a level of current income free from federal income tax as Putnam Management believes is consistent with the preservation of capital. The fund invests in investment-grade and some below-investment-grade municipal bonds. The fund may be appropriate for investors seeking tax-free income who are willing to accept a moderate degree of risk, including risk associated with the use of leverage.

Highlights

For the 12 months ended April 30, 2007, Putnam Municipal Opportunities Trust had a total return of 7.75% at net asset value (NAV) and 9.64% at market price.

The fund’s benchmark, the Lehman Municipal Bond Index, returned 5.78% .

The average return for the fund’s Lipper category, General Municipal Debt Funds (leveraged closed-end), was 7.42% .

Additional fund performance, comparative performance, and Lipper data can be found in the performance section beginning on page 10.

Performance

It is important to note that a fund’s performance at market price usually differs from its results at NAV. Although market price performance generally reflects investment results, it may also be influenced by several other factors, including changes in investor perceptions of the fund or its investment manager, market conditions, fluctuations in supply and demand for the fund’s shares, and changes in fund distributions.

Report from the fund managers

The year in review

During your fund’s fiscal year, which ended April 30, 2007, strong demand from yield-hungry investors fueled a rally in lower-quality municipal bonds, which have benefited from solid credit fundamentals as a result of the economic recovery. Although the fund was underweighted in this sector relative to many of its peers, the portfolio’s mix of lower-quality holdings nevertheless proved rewarding, especially among tobacco settlement and single-family housing bonds. Thanks to positive market conditions and our successful security selection — as well as the pre-refunding of two portfolio holdings — the fund’s results at net asset value (NAV) surpassed those of its benchmark, the Lehman Municipal Bond Index, and the average return for its Lipper peer group. We believe fund performance could have been stronger if we had not limited exposure to bonds with maturities greater than 15 years, which rallied during the period, but we considered it the most prudent strategy given our interest-rate outlook.

Market overview

Following a string of 17 consecutive increases in the federal funds rate, the Federal Reserve Board (the Fed) suspended its credit-tightening program in August 2006, holding this benchmark rate for overnight loans between banks steady at 5.25% . Since then, statements from the Federal Open Market Committee, the central bank’s policy-setting panel, have indicated that future rate decisions will depend on whether the Fed concludes that inflation or slower growth represents the greater risk to the economy.

For the period as a whole, yields on shorter-term bonds were essentially unchanged, while yields on longer-term bonds declined. As this occurred, the yield curve — a graphical representation of differences in yield for bonds of comparable quality and different maturities — flattened modestly. This flattening indicated that the yield advantage of longer-term bonds had declined significantly. (These bonds typically offer higher yields to investors to compensate them from the greater risk of a longer-term investment.) Tax-exempt bonds with maturities greater than five years performed better than comparable Treasury bonds, while shorter-maturity municipals underperformed comparable Treasuries.

A generally stable credit environment, coupled with solid demand from buyers searching for higher yields, contributed to the strong relative performance of lower-rated bonds throughout the period. Although the performance of bonds at the lower end of the credit spectrum — those rated below Baa — pulled back somewhat in March, the rally in this area of the credit spectrum resumed in April. As a result, lower-rated bonds again performed better than higher-rated bonds for the period. Non-rated bonds also gained in value, thanks to limited issuance and robust demand. Investors should remember that bond prices move in the opposite direction of their yields. Overall, the yields of lower-rated bonds were higher at the end than at the start of the period. However, these yields declined during the period as the prices of lower-rated bonds rose to reflect increased demand, and the yield advantages that had initially drawn investor attention became less pronounced.

The performance of airline-related industrial development bonds (IDBs) was exceptional, as trends in domestic airline travel remained healthy. Additional groups that posted solid results during the period included securities issued by long-term care facilities and toll roads. Tobacco settlement bonds, meanwhile, underperformed other credit-sensitive sectors somewhat, but still performed better than higher-rated bonds due to the robust yields offered by these securities.

Strategy overview

Given our expectation for rising interest rates, we maintained a short (defensive) portfolio duration relative to the fund’s Lipper peer group. This strategy detracted moderately from results since bonds with intermediate and long maturities generally outperformed those with shorter maturities. Duration is a measure of a fund’s sensitivity to changes in interest rates. Having a shorter-duration portfolio may help protect principal when interest rates rise, but it can reduce appreciation potential when rates fall. By the end of the period, we had extended the fund’s duration somewhat, but it still remained modestly short compared to the peer group average.

Despite a credit-rating downgrade, the fund’s position in general obligation bonds issued by Puerto Rico contributed positively to returns. In May 2006, financial turmoil led to a partial government shutdown, prompting the credit downgrade and causing the prices of uninsured Puerto Rico bonds to decline. We saw these developments as an opportunity to increase the fund’s holdings at favorable price levels, and as a result, the fund subsequently benefited from a substantial rally in Puerto Rico bonds.

Comparison of the fund’s maturity and duration

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


Average effective duration and average effective maturity take into account put and call features, where applicable, and reflect prepayments for mortgage-backed securities. Duration is usually shorter than maturity because it reflects interest payments on a bond prior to its maturity. Duration may be higher for funds that use leverage, which magnifies the effects of interest-rate changes.

During the second half of the fiscal year, we reduced the fund’s exposure to these bonds — selling into the rally’s strength — as credit spreads narrowed.

The fund’s higher overall credit quality held back performance as the lower-quality tiers of the municipal bond market delivered the strongest results during the period. We’ve been redeploying assets away from the lower-quality bonds, which are overpriced in our estimation, and adding bonds rated BBB or A by Standard & Poor’s and Baa and A by Moody’s. In our opinion, these bonds offer better value and less risk.

The fund’s underweight position in airline-related IDBs, relative to its peer group, detracted from performance as this sector posted strong results for the period. Passenger traffic is very high, and airlines have increased ticket prices to compensate for higher fuel costs while reducing the number of flights in an effort to eliminate excess capacity. Given the recovering fundamentals and rising profits in this sector, we will be looking for opportunities to bring the fund’s exposure back up to a more neutral weighting relative to the fund’s peer group.

Your fund’s holdings

The fund’s considerable exposure to tobacco settlement bonds was a positive contributor to performance for thefiscal year. Limited issuance of these securities, coupled with strong investor demand, provided solid supply-and-demand support for the sector and boosted results. At the close of the fiscal year on April 30, tobacco bonds, which generally are rated BBB by Standard & Poor’s, were yielding 120 basis points, or 1.20%, higher than municipal bonds rated AAA. (Payments from tobacco settlement bonds are secured by income promised to various states through settlements from tobacco companies.)

We think that this overweight position in tobacco settlement bonds has enabled the fund to earn above-average income levels with limited risk. Viewed another way, other BBB-rated or lower credit quality investments, such as hospital bonds, may only offer 50 to 60 basis points more income than AAA-rated bonds and carry significantly more risk. Given our favorable view of the tobacco settlement sector and the value it offers, we anticipate that we will maintain this overweight during the 2008 fiscal year. The fund holds tobacco settlement bonds issued by the states of California, New Jersey, New York, Rhode Island, South Carolina, Washington and Wisconsin.

Two of the fund’s holdings, Lancaster County Hospital Authority revenue bonds and New Jersey State Educational Facility Authority revenue bonds for Rowan University, were pre-refunded during the period, with a

Credit quality overview

Credit qualities shown as a percentage of portfolio value as of 4/30/07. A bond rated Baa or higher (MIG3/VMIG3 or higher, for short-term debt) is considered investment grade. The chart reflects Moody’s ratings; percentages may include bonds not rated by Moody's but considered by Putnam Management to be of comparable quality. Ratings will vary over time.


positive impact on performance. Pre-refundings occur when an issuer refinances an older, higher-coupon bond by issuing new bonds at current, lower interest rates. The proceeds are then invested in a secure investment, usually U.S. Treasury securities, that matures at the older bond’s first call date. The secure backing has the effect of raising the bond’s perceived credit rating while the shorter effective maturity lowers its interest-rate risk. Since both developments are favorable for investors, bond prices often rise after pre-refunding. Additionally, in the case of Lancaster Hospital, Standard & Poor’s upgraded the bonds from A to AA– in March and assigned a stable outlook. Lancaster expects to bring a new $50 million bond issuance to market in August, but we think it will have a negligible effect on key credit metrics since we expect the hospital’s exceptionally strong profitability and cash liquidity levels to continue to grow.

Relative to the fund’s peer group, we maintained an overweight position in single-family housing bonds. This strategy proved helpful to results, as declining mortgage prepayments continued to support bonds in this sector. Higher demand from investors looking for competitive yields also contributed to the sector’s outperformance. During the period, we purchased $1 million of single-family mortgage revenue bonds issued by the Texas Housing Authority.

Please note that the holdings discussed in this report may not have been held by the fund for the entire period. Portfolio composition is subject to review in accordance with the fund’s investment strategy and may vary in the future.

Of special interest

Merger with two other Putnam closed-end funds proposed

During the period, Putnam Investments and the Board of Trustees of the Putnam Funds announced a comprehensive initiative intended to concentrate the lineup of closed-end funds managed by Putnam Investments. The initiative includes a proposal to merge Putnam Investment Grade Municipal Trust and Putnam Municipal Bond Fund into your fund.

This merger must be approved by the common and preferred shareholders of all three funds. The Trustees believe it is in the best interests of shareholders of each fund because it would significantly increase the size of the combined fund. A larger asset size could reduce fund expenses and increase the liquidity in the trading market for fund shares. Proxy statements, which will include additional pertinent information to enable you to make an informed decision about the merger, are scheduled for mailing in the coming months. If approved by shareholders, the merger is expected to take place in the fall of 2007.

Monthly dividend adjusted

Given the narrowing of the yield spread between higher-and lower-rated municipal bonds, the opportunities for finding relatively high-yielding investments have become more limited, especially in light of our commitment to focusing on sound, creditworthy investments. Furthermore, the use of leverage became less profitable for the fund during the fiscal period when the spread between short- and long-term yields narrowed. To reflect the reduction in earnings, the dividend was reduced from $0.0562 to $0.0479 per share in May 2006.

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.

At the end of the period, the U.S. economy had expanded at less than what economists generally consider to be its long-term potential (about 3% annually) for three consecutive quarters. Clearly, some areas of the economy have softened while others continue to grow. At the same time, the Fed still appears concerned about heightened risks for both inflation and slower growth. Given this environment, we believe the Fed is likely to continue to hold interest rates steady until more data becomes available to clarify the economy’s direction. Therefore, we plan to maintain a neutral duration strategy until longer-range Fed policy becomes clearer.

In our view, the extended rally among lower-rated, higher-yielding bonds may be in its final stages. We base this view, in part, on the fact that the difference in yield between Aaa-rated bonds and Baa-rated bonds — the highest and lowest investment-grade ratings, respectively — remains near an all-time low. In other words, the higher-income advantage available to those willing to assume additional credit risk by investing in lower-rated bonds has diminished to the lowest level in over seven years. It has been our experience that when investor demand is this elevated, many high-yielding securities can become overpriced. We continue to believe that this is not the most opportune time to reach too far out in terms of bond maturity (i.e., extend duration by investing in longer-dated securities) or too far down in quality in pursuit of higher income. Over the near term, we intend to focus on certain market sectors — notably, single-family housing and power company IDBs —where we believe the fund may benefit in an environment of moderating economic growth without being exposed to undue risk.

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. Capital gains, if any, are taxable for federal and, in most cases, state purposes. For some investors, investment income may be subject to the federal alternative minimum tax. Income from federally exempt funds may be subject to state and local taxes. Please consult with your tax advisor for more information. 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. The fund uses leverage, which involves risk and may increase the volatility of the fund’s net asset value. The fund’s shares trade on a stock exchange at market prices, which may be higher or lower than the fund’s net asset value.

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 your fund’s management contract and administrative services contract with Putnam Management. In this regard, the Board of Trustees, with the assistance of its Contract Committee consisting solely of Trustees who are not “interested persons” (as such term is defined in the Investment Company Act of 1940, as amended) of the Putnam funds (the “Independent Trustees”), requests and evaluates all information it deems reasonably necessary under the circumstances. Over the course of several months ending in June 2006, the Contract Committee met four times to consider 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 management contract and administrative services contract, effective July 1, 2006.

This approval was based on the following conclusions:

That the fee schedule in effect for your fund (which includes fees paid under the administrative services contract) represented 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 services, and

That such fee schedule represented 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 and how the Trustees considered these factors are described below, although individual Trustees may have evaluated the information presented differently, giving different weights to various factors. It is also important to recognize that the fee arrangements for your fund and the other Putnam funds are the result of many years of review and discussion between the Independent Trustees and Putnam Management, that certain aspects of such arrangements may receive greater scrutiny in some years than others, and that the Trustees’ conclusions may be based, in part, on their consideration of these same arrangements in prior years.

Management fee schedules and categories; total expenses

The Trustees reviewed the management (and administrative services, if applicable) fee schedules in effect for all Putnam funds, including fee levels and breakpoints, and the assignment of funds to particular fee categories. In reviewing fees and expenses, the Trustees generally focused their attention on material changes in circumstances — for example, changes in a fund’s size or investment style, changes in Putnam Management’s operating costs, or changes in competitive practices in the mutual fund industry — that suggest that consideration of fee changes might be warranted. The Trustees concluded that the circumstances did not warrant changes to the management and administrative services fee structure of your fund, which had been carefully developed over the years, re-examined on many occasions and adjusted where appropriate. The Trustees focused on two areas of particular interest, as discussed further below:

Competitiveness. The Trustees reviewed comparative fee and expense information for competitive funds, which indicated that, in a custom peer group of competitive funds selected by Lipper Inc., your fund ranked in the 75th percentile in management fees and in the 63rd percentile in total expenses as of December 31, 2005 (the first percentile being the least expensive funds and the 100th percentile being the most expensive funds). The Trustees expressed their intention to monitor this information closely to ensure that fees and expenses of your fund continue to meet evolving competitive standards.

Economies of scale. In recent years, the Trustees have examined the operation of the existing breakpoint structure during periods of both growth and decline in asset levels. (A “breakpoint” is a reduction in fee rates that applies to additional assets once speci-fied asset levels are reached.) The Trustees concluded that the fee schedules in effect for the funds represented an appropriate sharing of economies of scale at current asset levels. In reaching this conclusion, the Trustees considered the Contract Committee’s stated intent to continue to work with Putnam Management to plan for an eventual resumption in the growth of

15


assets, including a study of potential economies that might be produced under various growth assumptions.

In connection with their review of the management fees and total expenses of the Putnam funds, the Trustees also reviewed the costs of the services to be provided and profits to be realized by Putnam Management and its affiliates from the relationship with the funds. This information included trends in revenues, expenses and profitability of Putnam Management and its affiliates relating to the investment management and distribution services provided to the funds. In this regard, the Trustees also reviewed an analysis of Putnam Management’s revenues, expenses and profitability with respect to the funds’ management contracts, allocated on a fund-by-fund basis. Because many of the costs incurred by Putnam Management in managing the funds are not readily identifiable to particular funds, the Trustees observed that the methodology for allocating costs is an important factor in evaluating Putnam Management’s costs and profitability, both as to the Putnam funds in the aggregate and as to individual funds. The Trustees reviewed Putnam Management’s cost allocation methodology with the assistance of independent consultants and concluded that this methodology was reasonable and well-considered.

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 your fund’s management contract. The Trustees were assisted in their review of the Putnam funds’ investment process and performance by the work of the Investment Process Committee of the Trustees and the Investment Oversight Committees of the Trustees, which meet on a regular monthly basis with the funds’ portfolio teams throughout the year. The Trustees concluded that Putnam Management generally provides 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 — but also recognize that this 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 each 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 discussed with senior management of Putnam Management the factors contributing to such underperformance 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 to address areas of underperformance. In particular, they noted the important contributions of Putnam Management’s leadership in attracting, retaining and supporting high-quality investment professionals and in systematically implementing an investment process that seeks to merge the best features of fundamental and quantitative analysis. The Trustees indicated their intention to continue to monitor performance trends to assess the effectiveness of these changes and to evaluate whether additional changes to address areas of underperformance are warranted.

In the case of your fund, the Trustees considered that your fund’s common share cumulative total return performance at net asset value was in the following percentiles of its Lipper Inc. peer group (Lipper General Municipal Debt Funds (leveraged closed-end)) (compared using tax-adjusted performance to recognize the different federal income tax treatment for capital gains distributions and exempt-interest distributions) for the one-, three- and five-year periods ended March 31, 2006 (the first percentile being the best performing funds and the 100th percentile being the worst performing funds):

One-year period  Three-year period  Five-year period 

75th  49th  42nd 

(Because of the passage of time, these performance results may differ from the performance results for more recent periods shown elsewhere in this report. Over the one-, three- and five-year periods ended March 31, 2006, there were 61, 58, and 46 funds, respectively, in your fund’s Lipper peer group.* Past performance is no guarantee of future performance.)

* The percentile rankings for your fund’s common share annualized total return performance in the Lipper General Municipal Debt Funds (leveraged closed-end) category for the one-, five- and ten-year periods ended March 31, 2007, were 37%, 77%, and 68%, respectively. Over the one-, five- and ten-year periods ended March 31, 2007, the fund ranked 21 out of 56, 39 out of 50, and 27 out of 39 funds, respectively. Unlike the information above, these rankings reflect performance before taxes. Note that this more recent information was not available when the Trustees approved the continuance of your fund’s management contract.

16


As a general matter, the Trustees concluded that cooperative efforts between the Trustees and Putnam Management represent the most effective way to address investment performance problems. The Trustees noted that investors in the Putnam funds have, in effect, placed their trust in the Putnam organization, under the oversight of the funds’ Trustees, to make appropriate decisions regarding the management of the funds. Based on the responsiveness of Putnam Management in the recent past to Trustee concerns about investment performance, the Trustees concluded that it is preferable to seek change within Putnam Management to address performance shortcomings. In the Trustees’ view, the alternative of terminating a management contract and engaging a new investment adviser for an underperforming fund would entail significant disruptions and would not 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 benefits related to brokerage and soft-dollar allocations, whereby a portion of the commissions paid by a fund for brokerage may be used to acquire research services that may be useful to Putnam Management in managing the assets of the fund and of other clients. The Trustees indicated their continued intentto monitor the potential benefits associated with the allocation of fund brokerage to ensure that the principle of seeking “best price and execution” remains paramount in the portfolio trading process.

The Trustees’ annual review of your fund’s management contract also included the review of your fund’s custodian and investor servicing agreements with Putnam Fiduciary Trust Company, which provide benefits to affiliates of Putnam Management.

Comparison of retail and institutional fee schedules

The information examined by the Trustees as part of their annual contract review has included for many years information regarding fees charged by Putnam Management and its affiliates to institutional clients such as defined benefit pension plans, college endowments, etc. This information included comparison of such fees with fees charged to the funds, as well as a detailed assessment of the differences in the services provided to these two types of clients. The Trustees observed, in this regard, that the differences in fee rates between institutional clients and the 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 reflect to a substantial degree historical competitive forces operating in separate market places. The Trustees considered the fact that fee rates across all asset sectors are higher on average for funds than for institutional clients, as well as the differences between the services that Putnam Management provides to the Putnam funds and those that it provides to institutional clients of the firm, but did not rely on such comparisons to any significant extent in concluding that the management fees paid by your fund are reasonable.

Approval of new management contracts in connection with pending change in control

As discussed in the “Message from the Trustees” at the beginning of this shareholder report, on February 1, 2007, Marsh & McLennan Companies, Inc. announced that it had signed a defini-tive agreement to sell its ownership interest in Putnam Investments Trust, the parent company of Putnam Management and its affiliates, to Great-West Lifeco Inc., a member of the Power Financial Corporation group of companies. In mid-May, shareholders voted overwhelmingly in favor of the proposed transaction. While the transaction is still subject to regulatory approvals and other conditions, it is currently expected to be completed by the middle of 2007.

At an in-person meeting on February 8–9, 2007, the Trustees considered the approval of new management contracts for each Putnam fund proposed to become effective upon the closing of the transaction, and the filing of a preliminary proxy statement. At an in-person meeting on March 8–9, 2007, the Trustees considered the approval of the final forms of the proposed new management contracts for each Putnam fund and the proxy statement. They reviewed the terms of the proposed new management contracts and the differences between the proposed new management contracts and the current management contracts (and, in the case of your fund, the administrative services contract). They noted that the terms of the proposed new management contracts were substantially identical to the current management contracts (and, in the case of your fund, addressed the provision of both investment management and administrative services and included a single fee

17


for both of these services), except for certain changes developed at the initiative of the Trustees and designed largely to address inconsistencies among various of the existing contracts, which had been developed and implemented at different times in the past. In considering the approval of the proposed new management contracts, the Trustees also considered, as discussed further in the proxy statement, various matters relating to the transaction. Finally, in considering the proposed new management contracts, the Trustees also took into account their deliberations and conclusions (discussed above in the preceding paragraphs of the “Trustee Approval of Management Contract” section) in connection with the most recent annual approval of the continuance of the Putnam funds’ management contracts effective July 1, 2006, and the extensive materials that they had reviewed in connection with that approval process. Based upon the foregoing considerations, on March 9, 2007, the Trustees, including all of the Independent Trustees, unanimously approved the proposed new management contracts and determined to recommend their approval to the shareholders of the Putnam funds. There is no change in the aggregate rate that your fund will pay to Putnam Management for investment management and administrative services.

Financial statements

These sections of the report, as well as the accompanying Notes, preceded by the Report of Independent Registered Public Accounting Firm, 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. (For funds with preferred shares, the amount subtracted from total assets includes the liquidation preference of 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 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.

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of
Putnam Municipal Opportunities Trust:

In our opinion, the accompanying statement of assets and liabilities, including the fund’s portfolio, 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 Municipal Opportunities Trust (the “fund”) at April 30, 2007, and the results of its operations, the changes in its net assets and the financial highlights for each of 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 the standards of the Public Company Accounting Oversight Board (United States). Those standards 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 April 30, 2007 by correspondence with the custodian, provide a reasonable basis for our opinion.

Notes to financial statements 4/30/07

Note 1: Significant accounting policies

Putnam Municipal Opportunities Trust (the “fund”) is registered under the Investment Company Act of 1940, as amended, as a non-diversified, closed-end management investment company. The fund's investment objective is to seek as high a level of current income exempt from federal 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 the preservation of capital. The fund intends to achieve its objective by investing in a portfolio of investment grade and some below investment-grade municipal bonds selected by Putnam Management.

In the normal course of business, the fund enters into contracts that may include agreements to indemnify another party under given circumstances. The fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be, but have not yet been, made against the fund. However, the fund expects the risk of material loss to be remote.

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 Tax-exempt bonds and notes are generally 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. Certain investments are also valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees. The fair value of securities is generally determined as the amount that the fund could reasonably expect to realize from an orderly disposition of such securities over a reasonable period of time. By its nature, a fair value price is a good faith estimate of the value of a security at a given point in time and does not reflect an actual market price, which may be different by a material amount.

B) Security transactions and related investment income Security transactions are recorded on the trade date (the 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, or for other investment purposes. The fund may also write options on swaps or 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.

D) 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 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 April 30, 2007, the fund had a capital loss carryover of $21,500,758 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 

$2,526,324  April 30, 2008 

1,503,027  April 30, 2009 

2,243,569  April 30, 2010 

3,588,009  April 30, 2011 

8,885,378  April 30, 2012 

2,388,286  April 30, 2013 

366,165  April 30, 2015 


Pursuant to federal income tax regulations applicable to regulated investment companies, the fund has elected to defer to its fiscal year ending April 30, 2008 $457,139 of losses recognized during the period November 1, 2006 to April 30, 2007.

E) Distributions to shareholders Distributions to common and preferred 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. Dividends on remarketed preferred shares become payable when, as and if declared by

35


the Trustees. Each dividend period for the remarketed preferred shares is generally a 28-day period for Series A and a 7-day period for Series B and Series C. The applicable dividend rate for the remarketed preferred shares on April 30, 2007 was 3.65% for Series A, 3.95% for Series B and 3.92% for Series C. 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/or permanent differences of post-October loss deferrals, dividends payable 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 April 30, 2007, the fund reclassified $17,105 to increase distributions in excess of net investment income and $17,105 to decrease accumulated net realized losses.

The tax basis components of distributable earnings and the federal tax cost as of April 30, 2007 were as follows:

Unrealized appreciation  $ 15,729,414 
Unrealized depreciation  (448,981) 
  ————————————— 
Net unrealized appreciation  15,280,433 
Undistributed tax exempt income  723,960 
Undistributed ordinary income  9,868 
Capital loss carryforward  (21,500,758) 
Post-October loss  (457,139) 
 
Cost for federal income tax purposes  $299,006,181 

F) Determination of net asset value Net asset value of the common shares is determined by dividing the value of all assets of the fund, less all liabilities and the liquidation preference of any outstanding remarketed preferred shares, by the total number of common shares outstanding as of year end.

Note 2: Management fee, administrative services and other transactions

Putnam Management is paid for management and investment advisory services quarterly based on the average weekly net assets of the fund. Such fee is based on the lesser of (i) an annual rate of 0.35% of the average weekly net assets of the fund attributable to common and preferred shares outstanding or (ii) the following annual rates expressed as a percentage of the fund’s average weekly net assets attributable to common and preferred shares outstanding: 0.45% of the first $500 million and 0.35% of the next $500 million, with additional breakpoints at higher asset levels.

In addition, the fund pays an administrative services fee to Putnam Management quarterly based on an annual rate of 0.20% of the average weekly net assets attributable to common and preferred shares outstanding. These amounts are included in Compensation of Manager in the Statement of operations.

If dividends payable on remarketed preferred shares during any dividend payment period plus any expenses attributable to remarketed preferred shares for that period exceed the fund’s gross income attributable to the proceeds of the remarketed preferred shares during that period, then the fee payable to Putnam Management for that period will be reduced by the amount of the excess (but not more than the effective management and administrative service fees rate under the contracts multiplied by the liquidation preference of the remarketed preferred shares outstanding during the period).

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 were provided by Putnam Fiduciary Trust Company (“PFTC”), a subsidiary of Putnam, LLC, and by State Street Bank and Trust Company. Custody fees are based on the fund’s asset level, the number of its security holdings and transaction volumes. Putnam Investor Services, a division of PFTC, provided investor servicing agent functions to the fund. Putnam Investor Services was paid a monthly fee for investor servicing at an annual rate of 0.05% of the fund’s average net assets. During the year ended April 30, 2007, the fund incurred $190,135 for custody and investor servicing agent functions provided by PFTC.

The fund has entered into arrangements with PFTC and State Street Bank and Trust Company whereby PFTC's and State Street Bank and Trust Company's fees are reduced by credits allowed on cash balances. For the year ended April 30, 2007, the fund's expenses were reduced by $106,619 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of which $289, 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, industry seminars and for certain compliance-related matters. Trustees also are reimbursed for expenses they incur relating to their services as Trustees. George Putnam, III, who was not an independent Trustee during the period, also receives the foregoing fees for his services as Trustee.

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 and were first elected prior to 2004. Benefits under the Pension Plan are equal to 50% of the Trustee's average annual attendance and retainer fees for the three years ended December 31, 2005. The retirement benefit is payable during a Trustee’s lifetime, beginning the year following retirement, for the number of years of service through December 31, 2006. 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.

Note 3: Purchases and sales of securities

During the year ended April 30, 2007, cost of purchases and proceeds from sales of investment securities other than short-term investments aggregated $39,807,211 and $39,887,930, respectively. There were no purchases or sales of U.S. government securities.

36


Note 4: Preferred shares

The Series A (800), Series B (1,620) and Series C (1,620) Remarketed Preferred shares are redeemable at the option of the fund on any dividend payment date at a redemption price of $50,000, $25,000 and $25,000 per share, respectively, plus an amount equal to any dividends accumulated on a daily basis but unpaid through the redemption date (whether or not such dividends have been declared) and, in certain circumstances, a call premium.

It is anticipated that dividends paid to holders of remarketed preferred shares will be considered tax-exempt dividends under the Internal Revenue Code of 1986. To the extent that the fund earns taxable income and capital gains by the conclusion of a fiscal year, it may be required to apportion to the holders of the remarketed preferred shares throughout that year additional dividends as necessary to result in an after-tax equivalent to the applicable dividend rate for the period.

Under the Investment Company Act of 1940, the fund is required to maintain asset coverage of at least 200% with respect to the remarketed preferred shares. Additionally, the fund’s bylaws impose more stringent asset coverage requirements and restrictions relating to the rating of the remarketed preferred shares by the shares’ rating agencies. Should these requirements not be met, or should dividends accrued on the remarketed preferred shares not be paid, the fund may be restricted in its ability to declare dividends to common shareholders or may be required to redeem certain of the remarketed preferred shares. At April 30, 2007, no such restrictions have been placed on the fund.

Note 5: Share repurchase program

In October 2005, the Trustees of your fund authorized Putnam Investments to implement a repurchase program on behalf of your fund, which would allow your fund to repurchase up to 5% of its outstanding common shares over the 12 months ending October 6, 2006 (based on shares outstanding as of October 7, 2005). In March 2006, the Trustees approved an increase in this repurchase program to allow the fund to repurchase a total of up to 10% of its outstanding common shares over the same period. In September 2006, the Trustees extended the program on its existing terms through October 6, 2007. Repurchases will only be made when the fund’s shares are trading at less than net asset value and in accordance with procedures approved by the fund’s Trustees.

For the year ended April 30, 2007, the fund repurchased 673,870 common shares for an aggregate purchase price of $7,799,198, which reflects a weighted-average discount from net asset value per share of 11.58% .

Note 6: Regulatory matters and litigation

In late 2003 and 2004, Putnam Management settled charges brought by the Securities and Exchange Commission (the “SEC”) and the Massachusetts Securities Division (“MSD”) in connection with excessive short-term trading by certain former Putnam employees and, in the case of charges brought by the MSD, excessive short-term trading by participants in some Putnam-administered 401(k) plans. Putnam Management agreed to pay $193.5 million in penalties and restitution, of which $153.5 million will be distributed to certain open-end Putnam funds and their shareholders after the SEC and MSD approve a distribution plan being developed by an independent consultant. The allegations of the SEC and MSD and related matters have served as the general basis for certain lawsuits, including purported class action lawsuits filed against Putnam Management and, in a limited number of cases, against some Putnam funds. Putnam Management believes that these lawsuits will have no material adverse effect on the funds or on Putnam Management's ability to provide investment management services. In addition, Putnam Management has agreed to bear any costs incurred by the Putnam funds as a result of these matters.

Putnam Management and Putnam Retail Management are named as defendants in a civil suit in which the plaintiffs allege that the management and distribution fees paid by certain Putnam funds were excessive and seek recovery under the Investment Company Act of 1940. Putnam Management and Putnam Retail Management have contested the plaintiffs’ claims and the matter is currently pending in the U.S. District Court for the District of Massachusetts. Based on currently available information, Putnam Management believes that this action is without merit and that it is unlikely to have a material effect on Putnam Management’s and Putnam Retail Management’s ability to provide services to their clients, including the fund.

Note 7: New accounting pronouncement

In June 2006, the Financial Accounting Standards Board (“FASB”) issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes (the “Interpretation”). The Interpretation prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken by a filer in the filer’s tax return. The Interpretation will become effective for fiscal years beginning after December 15, 2006 but will also apply to tax positions reflected in the fund’s financial statements as of that date. No determination has been made whether the adoption of the Interpretation will require the fund to make any adjustments to its net assets or have any other effect on the fund’s financial statements. The effects of implementing this pronouncement, if any, will be noted in the fund’s next semiannual financial statements.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, Fair Value Measurements (the “Standard”). The Standard defines fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. The Standard applies to fair value measurements already required or permitted by existing standards. The Standard is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Putnam Management is currently evaluating what impact the adoption of the Standard will have on the fund’s financial statements.

Note 8: Actions by the Trustees

The Trustees of the Putnam Funds have approved a plan to merge Putnam Municipal Bond Fund and Putnam Investment Grade Municipal Trust, both closed-end funds managed by Putnam Management, into the Fund. The transaction is expected to occur in the fall of 2007. It is subject to a number of conditions, including approval by common and preferred shareholders of the funds, and there is no guarantee that it will occur.

Federal tax information and compliance
certifications (Unaudited)

Federal tax information

The fund has designated 100% of dividends paid from net investment income during the fiscal year as tax exempt for Federal income tax purposes.

Compliance certifications

On November 15, 2006, your fund submitted a CEO annual certification to the New York Stock Exchange (“NYSE”) on which the fund’s principal executive officer certified that he was not aware, as of that date, of any violation by the fund of the NYSE’s Corporate Governance listing standards. In addition, as required by Section 302 of the Sarbanes-Oxley Act of 2002 and related SEC rules, the fund’s principal executive and principal financial officers have made quarterly certifications, included in filings with the SEC on Forms N-CSR and N-Q, relating to, among other things, the fund’s disclosure controls and procedures and internal control over financial reporting.

Item 2. Code of Ethics:

(a) The Fund’s principal executive, financial and accounting officers are employees of Putnam Investment Management, LLC, the Fund's investment manager. As such they are subject to a comprehensive Code of Ethics adopted and administered by Putnam Investments which is designed to protect the interests of the firm and its clients. The Fund has adopted a Code of Ethics which incorporates the Code of Ethics of Putnam Investments with respect to all of its officers and Trustees who are employees of Putnam Investment Management, LLC. For this reason, the Fund has not adopted a separate code of ethics governing its principal executive, financial and accounting officers.

(c) None

Item 3. Audit Committee Financial Expert:

The Funds' Audit and Compliance Committee is comprised solely of Trustees who are "independent" (as such term has been defined by the Securities and Exchange Commission ("SEC") in regulations implementing Section 407 of the Sarbanes-Oxley Act (the "Regulations")). The Trustees believe that each of the members of the Audit and Compliance Committee also possess a combination of knowledge and experience with respect to financial accounting matters, as well as other attributes, that qualify them for service on the Committee. In addition, the Trustees have determined that each of Mr. Patterson, Mr. Stephens, Mr. Leibler and Mr. Hill meets the financial literacy requirements of the New York Stock Exchange's rules and qualifies as an "audit committee financial expert" (as such term has been defined by the Regulations) based on their review of his pertinent experience and education. Certain other Trustees, although not on the Audit and Compliance Committee, would also qualify as "audit committee financial experts." The SEC has stated that the designation or identification of a person as an audit committee financial expert pursuant to this Item 3 of Form N-CSR does not impose on such person any duties, obligations or liability that are greater than the duties, obligations and liability imposed on such person as a member of the Audit and Compliance Committee and the Board of Trustees in the absence of such designation or identification.

Item 4. Principal Accountant Fees and Services:

The following table presents fees billed in each of the last two fiscal years for services rendered to the fund by the fund’s independent auditor:

Fiscal    Audit-     
year  Audit  Related  Tax  All Other 
ended  Fees  Fees  Fees  Fees 

 
 
April 30, 2007  $49,824  $23,880  $4,807  $ - 
April 30 , 2006  $43,383  $22,525  $4,916  $14 

For the fiscal years ended April 30, 2007 and April 30, 2006, the fund’s independent auditor billed aggregate non-audit fees in the amounts of $178,903 and $285,729 respectively, to the fund, Putnam Management and any entity controlling, controlled by or under common control with Putnam Management that provides ongoing services to the fund.

Audit Fees represent fees billed for the fund’s last two fiscal years.

Audit-Related Fees represent fees billed in the fund’s last two fiscal years for services traditionally performed by the fund’s auditor, including accounting consultation for proposed transactions or


concerning financial accounting and reporting standards and other audit or attest services not required by statute or regulation.

Tax Fees represent fees billed in the fund’s last two fiscal years for tax compliance, tax planning and tax advice services. Tax planning and tax advice services include assistance with tax audits, employee benefit plans and requests for rulings or technical advice from taxing authorities.

All Other Fees represent fees billed for services relating to an analysis of recordkeeping fees.

Pre-Approval Policies of the Audit and Compliance Committee. The Audit and Compliance Committee of the Putnam funds has determined that, as a matter of policy, all work performed for the funds by the funds’ independent auditors will be pre-approved by the Committee itself and thus will generally not be subject to pre-approval procedures.

The Audit and Compliance Committee also has adopted a policy to pre-approve the engagement by Putnam Management and certain of its affiliates of the funds’ independent auditors, even in circumstances where pre-approval is not required by applicable law. Any such requests by Putnam Management or certain of its affiliates are typically submitted in writing to the Committee and explain, among other things, the nature of the proposed engagement, the estimated fees, and why this work should be performed by that particular audit firm as opposed to another one. In reviewing such requests, the Committee considers, among other things, whether the provision of such services by the audit firm are compatible with the independence of the audit firm.

The following table presents fees billed by the fund’s independent auditor for services required to be approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X.

Item 5. Audit Committee of Listed Registrants

(a) The fund has a separately-designated Audit and Compliance Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended. The Audit and Compliance Committee of the fund's Board of Trustees is composed of the following persons:

Item 6. Schedule of Investments:


The registrant’s schedule of investments in unaffiliated issuers is included in the report to shareholders in Item 1 above.

Item 7. Disclosure of Proxy Voting Policies and Procedures For Closed-End Management Investment Companies:

Proxy voting guidelines of the Putnam funds

The proxy voting guidelines below summarize the funds’ positions on various issues of concern to investors, and give a general indication of how fund portfolio securities will be voted on proposals dealing with particular issues. The funds’ proxy voting service is instructed to vote all proxies relating to fund portfolio securities in accordance with these guidelines, except as otherwise instructed by the Proxy Coordinator, a member of the Office of the Trustees who is appointed to assist in the coordination and voting of the funds’ proxies.

The proxy voting guidelines are just that – guidelines. The guidelines are not exhaustive and do not include all potential voting issues. Because proxy issues and the circumstances of individual companies are so varied, there may be instances when the funds may not vote in strict adherence to these guidelines. For example, the proxy voting service is expected to bring to the Proxy Coordinator’s attention proxy questions that are company-specific and of a non-routine nature and that, even if covered by the guidelines, may be more appropriately handled on a case-by-case basis.

Similarly, Putnam Management’s investment professionals, as part of their ongoing review and analysis of all fund portfolio holdings, are responsible for monitoring significant corporate developments, including proxy proposals submitted to shareholders, and notifying the Proxy Coordinator of circumstances where the interests of fund shareholders may warrant a vote contrary to these guidelines. In such instances, the investment professionals will submit a written recommendation to the Proxy Coordinator and the person or persons designated by Putnam Management’s Legal and Compliance Department to assist in processing referral items pursuant to the funds’ “Proxy Voting Procedures.” The Proxy Coordinator, in consultation with the funds’ Senior Vice President, Executive Vice President, and/or the Chair of the Board Policy and Nominating Committee, as appropriate, will determine how the funds’ proxies will be voted. When indicated, the Chair of the Board Policy and Nominating Committee may consult with other members of the Committee or the full Board of Trustees.

The following guidelines are grouped according to the types of proposals generally presented to shareholders. Part I deals with proposals that have been put forth by management and approved and recommended by a company’s board of directors. Part II deals with proposals submitted by shareholders for inclusion in proxy statements. Part III addresses unique considerations pertaining to non-U.S. issuers.

The Putnam funds will disclose their proxy votes in accordance with the timetable established by SEC rules (i.e., not later than August 31 of each year for the most recent 12-month period ended June 30).


I. BOARD-APPROVED PROPOSALS

The vast majority of matters presented to shareholders for a vote involve proposals made by a company itself (sometimes referred to as “management proposals”), which have been approved and recommended by its board of directors. In view of the enhanced corporate governance practices currently being implemented in public companies and of the funds’ intent to hold corporate boards accountable for their actions in promoting shareholder interests, the funds’ proxies generally will be voted for the decisions reached by majority independent boards of directors, except as otherwise indicated in these guidelines. Accordingly, the funds’ proxies will be voted for board-approved proposals, except as follows:

Matters relating to the Board of Directors

Uncontested Election of Directors

The funds’ proxies will be voted for the election of a company’s nominees for the board of directors, except as follows:

* The funds will withhold votes for the entire board of directors if

the board does not have a majority of independent directors,

the board has not established independent nominating, audit, and compensation committees,

the board has more than 19 members or fewer than five members, absent special circumstances,

the board has not acted to implement a policy requested in a shareholder proposal that received the support of a majority of the shares of the company cast at its previous two annual meetings, or

the board has adopted or renewed a shareholder rights plan (commonly referred to as a “poison pill”) without shareholder approval during the current or prior calendar year.

* The funds will on a case-by-case basis withhold votes from the entire board of directors where the board has approved compensation arrangements for one or more company executives that the funds determine are unreasonably excessive relative to the company’s performance.

* The funds will withhold votes for any nominee for director who:


is considered an independent director by the company and who has received compensation from the company other than for service as a director (e.g., investment banking, consulting, legal, or financial advisory fees),

attends less than 75% of board and committee meetings without valid reasons for the absences (e.g., illness, personal emergency, etc.),

as a director of a public company (Company A), is employed as a senior executive of another public company (Company B) if a director of Company B serves as a senior executive of Company A (commonly referred to as an “interlocking directorate”), or

serves on more than five unaffiliated public company boards (for the purpose of this guideline, boards of affiliated registered investment companies will count as one board).

Commentary:

Board independence: Unless otherwise indicated, for the purposes of determining whether a board has a majority of independent directors and independent nominating, audit, and compensation committees, an “independent director” is a director who (1) meets all requirements to serve as an independent director of a company under the final NYSE Corporate Governance Rules (e.g., no material business relationships with the company and no present or recent employment relationship with the company (including employment of an immediate family member as an executive officer)), and (2) has not accepted directly or indirectly any consulting, advisory, or other compensatory fee from the company other than in his or her capacity as a member of the board of directors or any board committee. The funds’ Trustees believe that the receipt of any amount of compensation for services other than service as a director raises significant independence issues.

Board size: The funds’ Trustees believe that the size of the board of directors can have a direct impact on the ability of the board to govern effectively. Boards that have too many members can be unwieldy and ultimately inhibit their ability to oversee management performance. Boards that have too few members can stifle innovation and lead to excessive influence by management.

Time commitment: Being a director of a company requires a significant time commitment to adequately prepare for and attend the company’s board and committee meetings. Directors must be able to commit the time and attention necessary to perform their fiduciary duties in proper fashion, particularly in times of crisis. The funds’ Trustees are concerned about over-committed directors. In some cases, directors may serve on too many boards to make a meaningful contribution. This may be particularly true for senior executives of public companies (or other directors with substantially full-time employment) who serve on more than a few outside boards. The funds may withhold votes from such directors on a case-by-case basis where it appears that they may be unable to discharge their duties properly because of excessive commitments.


Interlocking directorships: The funds’ Trustees believe that interlocking directorships are inconsistent with the degree of independence required for outside directors of public companies.

Corporate governance practices: Board independence depends not only on its members’ individual relationships, but also on the board’s overall attitude toward management. Independent boards are committed to good corporate governance practices and, by providing objective independent judgment, enhancing shareholder value. The funds may withhold votes on a case-by-case basis from some or all directors who, through their lack of independence, have failed to observe good corporate governance practices or, through specific corporate action, have demonstrated a disregard for the interest of shareholders. Such instances may include cases where a board of directors has approved compensation arrangements for one or more members of management that, in the judgment of the funds’ Trustees, are excessive by reasonable corporate standards relative to the company’s record of performance.

Contested Elections of Directors

* The funds will vote on a case-by-case basis in contested elections of directors.

Classified Boards

* The funds will vote against proposals to classify a board, absent special circumstances indicating that shareholder interests would be better served by this structure.

Commentary: Under a typical classified board structure, the directors are divided into three classes, with each class serving a three-year term. The classified board structure results in directors serving staggered terms, with usually only a third of the directors up for re-election at any given annual meeting. The funds’ Trustees generally believe that it is appropriate for directors to stand for election each year, but recognize that, in special circumstances, shareholder interests may be better served under a classified board structure.

Other Board-Related Proposals

The funds will generally vote for board-approved proposals that have been approved by a majority independent board, and on a case-by-case basis on board-approved proposals where the board fails to meet the guidelines’ basic independence standards (i.e., majority of independent directors and independent nominating, audit, and compensation committees).

Executive Compensation

The funds generally favor compensation programs that relate executive compensation to a company’s long-term performance. The funds will vote on a case-by-case basis on board-approved proposals relating to executive compensation, except as follows:


* Except where the funds are otherwise withholding votes for the entire board of directors, the funds will vote for stock option and restricted stock plans that will result in an average annual dilution of 1.67% or less (based on the disclosed term of the plan and including all equity-based plans).

* The funds will vote against stock option and restricted stock plans that will result in an average annual dilution of greater than 1.67% (based on the disclosed term of the plan and including all equity-based plans).

* The funds will vote against any stock option or restricted stock plan where the company's actual grants of stock options and restricted stock under all equity-based compensation plans during the prior three (3) fiscal years have resulted in an average annual dilution of greater than 1.67% .

* The funds will vote against stock option plans that permit the replacing or repricing of underwater options (and against any proposal to authorize such replacement or repricing of underwater options).

* The funds will vote against stock option plans that permit issuance of options with an exercise price below the stock’s current market price.

* Except where the funds are otherwise withholding votes for the entire board of directors, the funds will vote for an employee stock purchase plan that has the following features: (1) the shares purchased under the plan are acquired for no less than 85% of their market value; (2) the offering period under the plan is 27 months or less; and (3) dilution is 10% or less.

Commentary: Companies should have compensation programs that are reasonable and that align shareholder and management interests over the longer term. Further, disclosure of compensation programs should provide absolute transparency to shareholders regarding the sources and amounts of, and the factors influencing, executive compensation. Appropriately designed equity-based compensation plans can be an effective way to align the interests of long-term shareholders with the interests of management. The funds may vote against executive compensation proposals on a case-by-case basis where compensation is excessive by reasonable corporate standards, or where a company fails to provide transparent disclosure of executive compensation. In voting on a proposal relating to executive compensation, the funds will consider whether the proposal has been approved by an independent compensation committee of the board.

Capitalization

Many proxy proposals involve changes in a company’s capitalization, including the authorization of additional stock, the issuance of stock, the repurchase of outstanding stock, or the approval of a stock split. The management of a company’s capital structure involves a number of important issues, including cash flow, financing needs, and market conditions that are unique to the circumstances of the company. As a result, the funds


will vote on a case-by-case basis on board-approved proposals involving changes to a company’s capitalization, except that where the funds are not otherwise withholding votes from the entire board of directors:

* The funds will vote for proposals relating to the authorization and issuance of additional common stock (except where such proposals relate to a specific transaction).

* The funds will vote for proposals to effect stock splits (excluding reverse stock splits).

* The funds will vote for proposals authorizing share repurchase programs.

Commentary: A company may decide to authorize additional shares of common stock for reasons relating to executive compensation or for routine business purposes. For the most part, these decisions are best left to the board of directors and senior management. The funds will vote on a case-by-case basis, however, on other proposals to change a company’s capitalization, including the authorization of common stock with special voting rights, the authorization or issuance of common stock in connection with a specific transaction (e.g., an acquisition, merger or reorganization), or the authorization or issuance of preferred stock. Actions such as these involve a number of considerations that may affect a shareholder’s investment and that warrant a case-by-case determination.

Acquisitions, Mergers, Reincorporations, Reorganizations and Other Transactions

Shareholders may be confronted with a number of different types of transactions, including acquisitions, mergers, reorganizations involving business combinations, liquidations, and the sale of all or substantially all of a company’s assets, which may require their consent. Voting on such proposals involves considerations unique to each transaction. As a result, the funds will vote on a case-by-case basis on board-approved proposals to effect these types of transactions, except as follows:

* The funds will vote for mergers and reorganizations involving business combinations designed solely to reincorporate a company in Delaware.

Commentary: A company may reincorporate into another state through a merger or reorganization by setting up a “shell” company in a different state and then merging the company into the new company. While reincorporation into states with extensive and established corporate laws – notably Delaware – provides companies and shareholders with a more well-defined legal framework, shareholders must carefully consider the reasons for a reincorporation into another jurisdiction, including especially an offshore jurisdiction.

Anti-Takeover Measures

Some proxy proposals involve efforts by management to make it more difficult for an outside party to take control of the company without the approval of the company’s board


of directors. These include the adoption of a shareholder rights plan, requiring supermajority voting on particular issues, the adoption of fair price provisions, the issuance of blank check preferred stock, and the creation of a separate class of stock with disparate voting rights. Such proposals may adversely affect shareholder rights, lead to management entrenchment, or create conflicts of interest. As a result, the funds will vote against board-approved proposals to adopt such anti-takeover measures, except as follows:

* The funds will vote on a case-by-case basis on proposals to ratify or approve shareholder rights plans; and

* The funds will vote on a case-by-case basis on proposals to adopt fair price provisions.

Commentary: The funds’ Trustees recognize that poison pills and fair price provisions may enhance shareholder value under certain circumstances. As a result, the funds will consider proposals to approve such matters on a case-by-case basis.

Other Business Matters

Many proxies involve approval of routine business matters, such as changing a company’s name, ratifying the appointment of auditors, and procedural matters relating to the shareholder meeting. For the most part, these routine matters do not materially affect shareholder interests and are best left to the board of directors and senior management of the company. The funds will vote for board-approved proposals approving such matters, except as follows:

* The funds will vote on a case-by-case basis on proposals to amend a company’s charter or bylaws (except for charter amendments necessary to effect stock splits, to change a company’s name or to authorize additional shares of common stock).

* The funds will vote against authorization to transact other unidentified, substantive business at the meeting.

* The funds will vote on a case-by-case basis on other business matters where the funds are otherwise withholding votes for the entire board of directors.

Commentary: Charter and bylaw amendments and the transaction of other unidentified, substantive business at a shareholder meeting may directly affect shareholder rights and have a significant impact on shareholder value. As a result, the funds do not view such items as routine business matters. Putnam Management’s investment professionals and the funds’ proxy voting service may also bring to the Proxy Coordinator’s attention company-specific items that they believe to be non-routine and warranting special consideration. Under these circumstances, the funds will vote on a case-by-case basis.


II. SHAREHOLDER PROPOSALS

SEC regulations permit shareholders to submit proposals for inclusion in a company’s proxy statement. These proposals generally seek to change some aspect of the company’s corporate governance structure or to change some aspect of its business operations. The funds generally will vote in accordance with the recommendation of the company’s board of directors on all shareholder proposals, except as follows:

* The funds will vote for shareholder proposals to declassify a board, absent special circumstances which would indicate that shareholder interests are better served by a classified board structure.

* The funds will vote for shareholder proposals to require shareholder approval of shareholder rights plans.

* The funds will vote on a case-by-case basis on shareholder proposals requiring companies to make payments under management severance agreements only if both of the following conditions are met:

the company undergoes a change in control, and

the change in control results in a loss of employment for the person receiving the severance payment.

* The funds will vote on a case-by-case basis on shareholder proposals requesting that the board adopt a policy to recoup, in the event of a significant restatement of financial results or significant extraordinary write-off, to the fullest extent practicable, for the benefit of the company, all performance-based bonuses or awards that were paid to senior executives based on the company having met or exceeded specific performance targets to the extent that the specific performance targets were not, in fact, met.

* The funds will vote for shareholder proposals requiring a company to report on its executive retirement benefits (e.g., deferred compensation, split-dollar life insurance, SERPs and pension benefits).

* The funds will vote for shareholder proposals requiring a company to disclose its relationships with executive compensation consultants (e.g., whether the company, the board or the compensation committee retained the consultant, the types of services provided by the consultant over the past five years, and a list of the consultant’s clients on which any of the company’s executives serve as a director).

* The funds will vote for shareholder proposals that are consistent with the funds’ proxy voting guidelines for board-approved proposals.

* The funds will vote on a case-by-case basis on other shareholder proposals where the funds are otherwise withholding votes for the entire board of directors.


Commentary: In light of the substantial reforms in corporate governance that are currently underway, the funds’ Trustees believe that effective corporate reforms should be promoted by holding boards of directors – and in particular their independent directors – accountable for their actions, rather than imposing additional legal restrictions on board governance through piecemeal proposals. Generally speaking, shareholder proposals relating to business operations are often motivated primarily by political or social concerns, rather than the interests of shareholders as investors in an economic enterprise. As stated above, the funds’ Trustees believe that boards of directors and management are responsible for ensuring that their businesses are operating in accordance with high legal and ethical standards and should be held accountable for resulting corporate behavior. Accordingly, the funds will generally support the recommendations of boards that meet the basic independence and governance standards established in these guidelines. Where boards fail to meet these standards, the funds will generally evaluate shareholder proposals on a case-by-case basis.

However, the funds generally support shareholder proposals to declassify a board or to require shareholder approval of shareholder rights plans The funds’ Trustees believe that these shareholder proposals further the goals of reducing management entrenchment and conflicts of interest, and aligning management’s interests with shareholders’ interests in evaluating proposed acquisitions of the company. The Trustees also believe that shareholder proposals to limit severance payments to appropriate situations may further these goals in some instances, and the funds will consider supporting these shareholder proposals on a case by case basis. (The funds’ Trustees will also consider whether the severance payments, taking all of the pertinent circumstances into account, constitute excessive compensation.)

The funds’ Trustees believe that performance-based compensation can be an effective tool for aligning management and shareholder interests. However, to fulfill its purpose, performance compensation should only be paid to executives if the performance targets are actually met. A significant restatement of financial results or a significant extraordinary write-off may reveal that executives who were previously paid performance compensation did not actually deliver the required business performance to earn that compensation. In these circumstances, it may be appropriate for the company to recoup this performance compensation. The fund will consider on a case by case basis shareholder proposals requesting that the board adopt a policy to recoup, in the event of a significant restatement of financial results or significant extraordinary write-off, performance-based bonuses or awards paid to senior executives based on the company having met or exceeded specific performance targets to the extent that the specific performance targets were not, in fact, met. The fund does not believe that such a policy should necessarily disadvantage a company in recruiting executives, as executives should understand that they are only entitled to performance compensation based on the actual performance they deliver.

The funds’ Trustees also believe that shareholder proposals that are intended to increase transparency, particularly with respect to executive compensation, without establishing rigid restrictions upon a company’s ability to attract and motivate talented executives, are


generally beneficial to sound corporate governance without imposing undue burdens. The funds will generally support shareholder proposals calling for reasonable disclosure.

III. VOTING SHARES OF NON-U.S. ISSUERS

Many of the Putnam funds invest on a global basis, and, as a result, they may be required to vote shares held in non-U.S. issuers – i.e., issuers that are incorporated under the laws of foreign jurisdictions and that are not listed on a U.S. securities exchange or the NASDAQ stock market. Because non-U.S. issuers are incorporated under the laws of countries and jurisdictions outside the U.S., protection for shareholders may vary significantly from jurisdiction to jurisdiction. Laws governing non-U.S. issuers may, in some cases, provide substantially less protection for shareholders. As a result, the foregoing guidelines, which are premised on the existence of a sound corporate governance and disclosure framework, may not be appropriate under some circumstances for non-U.S. issuers.

In many non-U.S. markets, shareholders who vote proxies of a non-U.S. issuer are not able to trade in that company’s stock on or around the shareholder meeting date. This practice is known as “share blocking.” In countries where share blocking is practiced, the funds will vote proxies only with direction from Putnam Management’s investment professionals.

In addition, some non-U.S. markets require that a company’s shares be re-registered out of the name of the local custodian or nominee into the name of the shareholder for the meeting. This practice is known as “share re-registration.” As a result, shareholders, including the funds, are not able to trade in that company’s stock until the shares are reregistered back in the name of the local custodian or nominee. In countries where share re-registration is practiced, the funds will generally not vote proxies.

The funds will vote proxies of non-U.S. issuers in accordance with the foregoing guidelines where applicable, except as follows:

Uncontested Election of Directors

Japan

* For companies that have established a U.S.-style corporate structure, the funds will withhold votes for the entire board of directors if

the board does not have a majority of outside directors,

the board has not established nominating and compensation committees composed of a majority of outside directors, or

the board has not established an audit committee composed of a majority of independent directors.


* The funds will withhold votes for the appointment of members of a company’s board of statutory auditors if a majority of the members of the board of statutory auditors is not independent.

Commentary:

Board structure: Recent amendments to the Japanese Commercial Code give companies the option to adopt a U.S.-style corporate structure (i.e., a board of directors and audit, nominating, and compensation committees). The funds will vote for proposals to amend a company’s articles of incorporation to adopt the U.S.-style corporate structure.

Definition of outside director and independent director: Corporate governance principles in Japan focus on the distinction between outside directors and independent directors. Under these principles, an outside director is a director who is not and has never been a director, executive, or employee of the company or its parent company, subsidiaries or affiliates. An outside director is “independent” if that person can make decisions completely independent from the managers of the company, its parent, subsidiaries, or affiliates and does not have a material relationship with the company (i.e., major client, trading partner, or other business relationship; familial relationship with current director or executive; etc.). The guidelines have incorporated these definitions in applying the board independence standards above.

Korea

* The funds will withhold votes for the entire board of directors if

the board does not have a majority of outside directors,

the board has not established a nominating committee composed of at least a majority of outside directors, or

the board has not established an audit committee composed of at least three members and in which at least two-thirds of its members are outside directors.

Commentary: For purposes of these guideline, an “outside director” is a director that is independent from the management or controlling shareholders of the company, and holds no interests that might impair performing his or her duties impartially from the company, management or controlling shareholder. In determining whether a director is an outside director, the funds will also apply the standards included in Article 415-2(2) of the Korean Commercial Code (i.e., no employment relationship with the company for a period of two years before serving on the committee, no director or employment relationship with the company’s largest shareholder, etc.) and may consider other business relationships that would affect the independence of an outside director.

United Kingdom


* The funds will withhold votes for the entire board of directors if

the board does not have at least a majority of independent non-executive directors,

the board has not established nomination committees composed of a majority of independent non-executive directors, or

the board has not established compensation and audit committees composed of (1) at least three directors (in the case of smaller companies, two directors) and (2) solely of independent non-executive directors.

* The funds will withhold votes for any nominee for director who is considered an independent director by the company and who has received compensation from the company other than for service as a director (e.g., investment banking, consulting, legal, or financial advisory fees).

Commentary:

Application of guidelines: Although the U.K.’s Combined Code on Corporate Governance (“Combined Code”) has adopted the “comply and explain” approach to corporate governance, the funds’ Trustees believe that the guidelines discussed above with respect to board independence standards are integral to the protection of investors in U.K. companies. As a result, these guidelines will be applied in a prescriptive manner.

Definition of independence: For the purposes of these guidelines, a non-executive director shall be considered independent if the director meets the independence standards in section A.3.1 of the Combined Code (i.e., no material business or employment relationships with the company, no remuneration from the company for non-board services, no close family ties with senior employees or directors of the company, etc.), except that the funds do not view service on the board for more than nine years as affecting a director’s independence.

Smaller companies: A smaller company is one that is below the FTSE 350 throughout the year immediately prior to the reporting year.

Canada

In January 2004, Canadian securities regulators issued proposed policies that would impose new corporate governance requirements on Canadian public companies. The recommended practices contained in these new corporate governance requirements mirror corporate governance reforms that have been adopted by the NYSE and other U.S. national securities exchanges and stock markets. As a result, the funds will vote on matters relating to the board of directors of Canadian issuers in accordance with the guidelines applicable to U.S. issuers.


Commentary: Like the U.K.’s Combined Code, the proposed policies on corporate governance issued by Canadian securities regulators embody the “comply and explain” approach to corporate governance. Because the funds’ Trustees believe that the board independence standards contained in the proxy voting guidelines are integral to the protection of investors in Canadian companies, these standards will be applied in a prescriptive manner.

Russia

* The funds will vote on a case-by-case basis for the election of nominees to the board of directors.

Commentary: In Russia, director elections are typically handled through a cumulative voting process. Cumulative voting allows shareholders to cast all of their votes for a single nominee for the board of directors, or to allocate their votes among nominees in any other way. In contrast, in “regular,” voting, shareholders may not give more than one vote per share to any single nominee. Cumulative voting can help to strengthen the ability of minority shareholders to elect a director.

In Russia, as in other emerging markets, standards of corporate governance are usually behind those in developed markets. Rather than vote against the entire board of directors, as the funds generally would in the case of a company whose board fails to meet the funds’ standards for independence, the funds may, on a case by case basis, cast all of their votes for one or more independent director nominees. The funds believe that it is important to increase the number of independent directors on the boards of Russian companies to mitigate the risks associated with dominant shareholders.

Other Matters

* The funds will vote for shareholder proposals calling for a majority of a company’s directors to be independent of management.

* The funds will vote for shareholder proposals seeking to increase the independence of board nominating, audit, and compensation committees.

* The funds will vote for shareholder proposals that implement corporate governance standards similar to those established under U.S. federal law and the listing requirements of U.S. stock exchanges, and that do not otherwise violate the laws of the jurisdiction under which the company is incorporated.

* The funds will vote on a case-by-case basis on proposals relating to (1) the issuance of common stock in excess of 20% of the company’s outstanding common stock where shareholders do not have preemptive rights, or (2) the issuance of common stock in excess of 100% of the company’s outstanding common stock where shareholders have preemptive rights.

As adopted February 9, 2007


Proxy Voting Procedures of the Putnam Funds

The proxy voting procedures below explain the role of the funds’ Trustees, the proxy voting service and the Proxy Coordinator, as well as how the process will work when a proxy question needs to be handled on a case-by-case basis, or when there may be a conflict of interest.

The role of the funds’ Trustees

The Trustees of the Putnam funds exercise control of the voting of proxies through their Board Policy and Nominating Committee, which is composed entirely of independent Trustees. The Board Policy and Nominating Committee oversees the proxy voting process and participates, as needed, in the resolution of issues that need to be handled on a case-by-case basis. The Committee annually reviews and recommends, for Trustee approval, guidelines governing the funds’ proxy votes, including how the funds vote on specific proposals and which matters are to be considered on a case-by-case basis. The Trustees are assisted in this process by their independent administrative staff (“Office of the Trustees”), independent legal counsel, and an independent proxy voting service. The Trustees also receive assistance from Putnam Investment Management, LLC (“Putnam Management”), the funds’ investment advisor, on matters involving investment judgments. In all cases, the ultimate decision on voting proxies rests with the Trustees, acting as fiduciaries on behalf of the shareholders of the funds.

The role of the proxy voting service

The funds have engaged an independent proxy voting service to assist in the voting of proxies. The proxy voting service is responsible for coordinating with the funds’ custodians to ensure that all proxy materials received by the custodians relating to the funds’ portfolio securities are processed in a timely fashion. To the extent applicable, the proxy voting service votes all proxies in accordance with the proxy voting guidelines established by the Trustees. The proxy voting service will refer proxy questions to the Proxy Coordinator (described below) for instructions under circumstances where: (1) the application of the proxy voting guidelines is unclear; (2) a particular proxy question is not covered by the guidelines; or (3) the guidelines call for specific instructions on a case-by-case basis. The proxy voting service is also requested to call to the Proxy Coordinator’s attention specific proxy questions that, while governed by a guideline, appear to involve unusual or controversial issues. The funds also utilize research services relating to proxy questions provided by the proxy voting service and by other firms.

The role of the Proxy Coordinator

Each year, a member of the Office of the Trustees is appointed Proxy Coordinator to assist in the coordination and voting of the funds’ proxies. The Proxy Coordinator will deal directly with the proxy voting service and, in the case of proxy questions referred by the proxy voting service, will solicit voting recommendations and instructions from the Office of the Trustees, the Chair of the Board Policy and Nominating Committee, and Putnam Management’s investment professionals, as appropriate. The Proxy Coordinator is responsible for ensuring that these questions and referrals are responded to in a timely fashion and for transmitting appropriate voting instructions to the proxy voting service.

Voting procedures for referral items

As discussed above, the proxy voting service will refer proxy questions to the Proxy Coordinator under certain circumstances. When the application of the proxy voting guidelines is unclear or a particular proxy question is not covered by the guidelines (and does not involve investment considerations), the Proxy Coordinator will assist in interpreting the guidelines and, as appropriate,


consult with one of more senior staff members of the Office of the Trustees and the Chair of the Board Policy and Nominating Committee on how the funds’ shares will be voted.

For proxy questions that require a case-by-case analysis pursuant to the guidelines or that are not covered by the guidelines but involve investment considerations, the Proxy Coordinator will refer such questions, through a written request, to Putnam Management’s investment professionals for a voting recommendation. Such referrals will be made in cooperation with the person or persons designated by Putnam Management’s Legal and Compliance Department to assist in processing such referral items. In connection with each such referral item, the Legal and Compliance Department will conduct a conflicts of interest review, as described below under “Conflicts of Interest,” and provide a conflicts of interest report (the “Conflicts Report”) to the Proxy Coordinator describing the results of such review. After receiving a referral item from the Proxy Coordinator, Putnam Management’s investment professionals will provide a written recommendation to the Proxy Coordinator and the person or persons designated by the Legal and Compliance Department to assist in processing referral items. Such recommendation will set forth (1) how the proxies should be voted; (2) the basis and rationale for such recommendation; and (3) any contacts the investment professionals have had with respect to the referral item with non-investment personnel of Putnam Management or with outside parties (except for routine communications from proxy solicitors). The Proxy Coordinator will then review the investment professionals’ recommendation and the Conflicts Report with one of more senior staff members of the Office of the Trustees in determining how to vote the funds’ proxies. The Proxy Coordinator will maintain a record of all proxy questions that have been referred to Putnam Management’s investment professionals, the voting recommendation, and the Conflicts Report.

In some situations, the Proxy Coordinator and/or one of more senior staff members of the Office of the Trustees may determine that a particular proxy question raises policy issues requiring consultation with the Chair of the Board Policy and Nominating Committee, who, in turn, may decide to bring the particular proxy question to the Committee or the full Board of Trustees for consideration.

Conflicts of interest

Occasions may arise where a person or organization involved in the proxy voting process may have a conflict of interest. A conflict of interest may exist, for example, if Putnam Management has a business relationship with (or is actively soliciting business from) either the company soliciting the proxy or a third party that has a material interest in the outcome of a proxy vote or that is actively lobbying for a particular outcome of a proxy vote. Any individual with knowledge of a personal conflict of interest (e.g., familial relationship with company management) relating to a particular referral item shall disclose that conflict to the Proxy Coordinator and the Legal and Compliance Department and otherwise remove himself or herself from the proxy voting process. The Legal and Compliance Department will review each item referred to Putnam Management’s investment professionals to determine if a conflict of interest exists and will provide the Proxy Coordinator with a Conflicts Report for each referral item that (1) describes any conflict of interest; (2) discusses the procedures used to address such conflict of interest; and (3) discloses any contacts from parties outside Putnam Management (other than routine communications from proxy solicitors) with respect to the referral item not otherwise reported in an investment professional’s recommendation. The Conflicts Report will also include written confirmation that any recommendation from an investment professional provided under circumstances where a conflict of interest exists was made solely on the investment merits and without regard to any other consideration.

As adopted March 11, 2005

Item 8. Portfolio Managers of Closed-End Management Investment Companies


(a)(1) Investment management teams. Putnam Management’s, Putnam Investments Limited’s and The Putnam Advisory Company’s (for funds having Putnam Investments Limited and/or The Putnam Advisory Company as sub-manager) investment professionals are organized into investment management teams, with a particular team dedicated to a specific asset class. The members of the team or teams identified in the shareholder report included in Item 1 of this report manage the fund’s investments. The names of all team members can be found at www.putnam.com.

The team members identified as the fund’s Portfolio Leader(s) and Portfolio Member(s) coordinate team efforts related to the fund and are primarily responsible for the day-today management of the fund’s portfolio. In addition to these individuals, each team also includes other investment professionals, whose analysis, recommendations and research inform investment decisions made for the fund.

Potential conflicts of interest in managing multiple accounts. Like other investment professionals with multiple clients, the fund’s Portfolio Leader(s) and Portfolio Member(s) may face certain potential conflicts of interest in connection with managing both the fund and the other accounts listed under “Other Accounts Managed by the Fund’s Portfolio Managers” at the same time. The paragraphs below describe some of these potential conflicts, which Putnam Management believes are faced by investment professionals at most major financial firms. As described below, Putnam Management and the Trustees of the Putnam funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance (“performance fee accounts”), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

• The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

• The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

• The trading of other accounts could be used to benefit higher-fee accounts (front- running).

• The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Putnam Management attempts to address these potential conflicts of interest relating to higher-fee accounts through various compliance policies that are generally intended to place all accounts, regardless of fee structure, on the same footing for investment management purposes. For example, under Putnam Management’s policies:

• Performance fee accounts must be included in all standard trading and allocation procedures with all other accounts.


• All accounts must be allocated to a specific category of account and trade in parallel with allocations of similar accounts based on the procedures generally applicable to all accounts in those groups (e.g., based on relative risk budgets of accounts).

• All trading must be effected through Putnam’s trading desks and normal queues and procedures must be followed (i.e., no special treatment is permitted for performance fee accounts or higher-fee accounts based on account fee structure).

• Front running is strictly prohibited.

• The fund’s Portfolio Leader(s) and Portfolio Member(s) may not be guaranteed or specifically allocated any portion of a performance fee.

As part of these policies, Putnam Management has also implemented trade oversight and review procedures in order to monitor whether particular accounts (including higher-fee accounts or performance fee accounts) are being favored over time.

Potential conflicts of interest may also arise when the Portfolio Leader(s) or Portfolio Member(s) have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, Putnam Management’s investment professionals do not have the opportunity to invest in client accounts, other than the Putnam funds. However, in the ordinary course of business, Putnam Management or related persons may from time to time establish “pilot” or “incubator” funds for the purpose of testing proposed investment strategies and products prior to offering them to clients. These pilot accounts may be in the form of registered investment companies, private funds such as partnerships or separate accounts established by Putnam Management or an affiliate. Putnam Management or an affiliate supplies the funding for these accounts. Putnam employees, including the fund’s Portfolio Leader(s) and Portfolio Member(s), may also invest in certain pilot accounts. Putnam Management, and to the extent applicable, the Portfolio Leader(s) and Portfolio Member(s) will benefit from the favorable investment performance of those funds and accounts. Pilot funds and accounts may, and frequently do, invest in the same securities as the client accounts. Putnam Management’s policy is to treat pilot accounts in the same manner as client accounts for purposes of trading allocation – neither favoring nor disfavoring them except as is legally required. For example, pilot accounts are normally included in Putnam Management’s daily block trades to the same extent as client accounts (except that pilot accounts do not participate in initial public offerings).

A potential conflict of interest may arise when the fund and other accounts purchase or sell the same securities. On occasions when the Portfolio Leader(s) or Portfolio Member(s) consider the purchase or sale of a security to be in the best interests of the fund as well as other accounts, Putnam Management’s trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to seek to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to the fund or another account if one account is favored over another in allocating the securities purchased or sold – for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account. Putnam Management’s trade


allocation policies generally provide that each day’s transactions in securities that are purchased or sold by multiple accounts are, insofar as possible, averaged as to price and allocated between such accounts (including the fund) in a manner which in Putnam Management’s opinion is equitable to each account and in accordance with the amount being purchased or sold by each account. Certain exceptions exist for specialty, regional or sector accounts. Trade allocations are reviewed on a periodic basis as part of Putnam Management’s trade oversight procedures in an attempt to ensure fairness over time across accounts.

“Cross trades,” in which one Putnam account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. Putnam Management and the fund’s Trustees have adopted compliance procedures that provide that any transactions between the fund and another Putnam-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of the fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than the fund. Depending on another account’s objectives or other factors, the Portfolio Leader(s) and Portfolio Member(s) may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to the fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by the Portfolio Leader(s) or Portfolio Member(s) when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts. As noted above, Putnam Management has implemented trade oversight and review procedures to monitor whether any account is systematically favored over time.

The fund’s Portfolio Leader(s) and Portfolio Member(s) may also face other potential conflicts of interest in managing the fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both the fund and other accounts.

(a)(3) Compensation of investment professionals. Putnam Management believes that its investment management teams should be compensated primarily based on their success in helping investors achieve their goals. The portion of Putnam Investments’ total incentive compensation pool that is available to Putnam Management’s Investment Division is based primarily on its delivery, across all of the portfolios it manages, of consistent, dependable and superior performance over time. The peer group for the fund,


which is identified in the shareholder report included in Item 1, is its broad investment category as determined by Lipper Inc. The portion of the incentive compensation pool available to each investment management team varies based primarily on its delivery, across all of the portfolios it manages, of consistent, dependable and superior performance over time on (i) for tax-exempt funds, a tax-adjusted basis to recognize the different federal income tax treatment for capital gains distributions and exempt-interest distributions a before-tax basis or (ii) for taxable funds, on a before-tax basis.

Consistent performance means being above median over one year.

· Dependable performance means not being in the 4th quartile of the peer group over one, three or five years.

· Superior performance (which is the largest component of Putnam Management’s incentive compensation program) means being in the top third of the peer group over three and five years.

In determining an investment management team’s portion of the incentive compensation pool and allocating that portion to individual team members, Putnam Management retains discretion to reward or penalize teams or individuals, including the fund’s Portfolio Leader(s) and Portfolio Member(s), as it deems appropriate, based on other factors. The size of the overall incentive compensation pool each year is determined by Putnam Management’s parent company, Marsh & McLennan Companies, Inc., and depends in large part on Putnam’s profitability for the year, which is influenced by assets under management. Incentive compensation is generally paid as cash bonuses, but a portion of incentive compensation may instead be paid as grants of restricted stock, options or other forms of compensation, based on the factors described above. In addition to incentive compensation, investment team members receive annual salaries that are typically based on seniority and experience. Incentive compensation generally represents at least 70% of the total compensation paid to investment team members.

(a)(4) Fund ownership. The following table shows the dollar ranges of shares of the fund owned by the professionals listed above at the end of the fund’s last two fiscal years, including investments by their immediate family members and amounts invested through retirement and deferred compensation plans.


N/A indicates the individual was not a Portfolio Leader or Portfolio Member as of the fund’s fiscal year end.

(b) Not applicable

The Board of Trustees announced a repurchase plan on October 7, 2005 for which 807,855 shares were approved for repurchase by the fund. The repurchase plan was approved through October 6, 2006. On March 10, 2006, the Trustees announced that the repurchase program was increased to allow repurchases of up to a total of 1,615,709 shares over the original term of the program. On September 15, 2006, the Trustees voted to extend the term of the repurchase program through October 6, 2007. This extension did not affect the number of shares eligible for repurchase under the program.
