What makes Putnam different?

A time-honored tradition in money management

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.

Funds for every investment goal

We offer a broad range of mutual funds and other financial products so investors and their financial representatives can build diversified portfolios.

A commitment to doing what’s right for investors

With a focus on investment performance, below-average expenses, and in-depth information about our funds, we put the interests of investors first and seek to set the standard for integrity and service.

Industry-leading service

We help investors, along with their financial representatives, make informed investment decisions with confidence.

In 1830, Massachusetts Supreme Judicial Court Justice Samuel Putnam established The Prudent Man Rule, a legal foundation for responsible money management.

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:

This November, Putnam Investments celebrates its 70th anniversary. From modest beginnings in Boston, Massachusetts, Putnam has grown into a global asset manager that serves millions of investors worldwide. Coincident with this anniversary, we are pleased to announce that Great-West Lifeco Inc. recently completed its purchase of Putnam Investments from Marsh & McLennan Companies, 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. With this change, Putnam becomes part of a successful organization with a longstanding commitment to high-quality investment management and financial services. The change in ownership is not expected to affect the Putnam funds, the way Putnam manages money, or the funds’ management teams.

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, was recently named President of the Funds, assuming this role from George Putnam, III. This change, together with the completion of the transaction with Great-West Lifeco, has enabled George Putnam to become an independent Trustee of the funds. Both George and Ed will continue serving on the Board of Trustees in our collective role of overseeing the Putnam funds on your behalf.

Lastly, we are pleased to announce that a new independent Trustee, Robert J. Darretta, has joined your fund’s Board of Trustees. Mr. Darretta brings extensive leadership experience in corporate finance and accounting. He is a former Vice Chairman of the Board of Directors of Johnson & Johnson, one of the leading U.S. health-care and consumer products companies, where he also served as Chief Financial Officer, Executive Vice President, and Treasurer.

Although the mutual fund industry has undergone many changes since George Putnam introduced his innovative balanced fund in 1937, Putnam’s guiding principles have not. As we celebrate Putnam’s 70-year milestone, we look forward to Putnam continuing its long tradition of prudent money management and to the new chapter opened by its recent change in ownership. As always, we thank you for your support of the Putnam funds.

Putnam Money Market Fund: seeking to offer accessibility
and current income with relatively low risk

For most people, keeping part of their savings in a low-risk, easily accessible place is an essential part of their overall investment strategy. Putnam Money Market Fund can play a valuable role in many investors’ portfolios because it seeks to provide stability of  principal and liquidity to meet short-term needs. In addition, the fund aims to provide investors with current income at short-term rates.

By investing in high-quality short-term money market instruments for which there are deep and liquid markets, the fund’s risk of losing principal is very low. Putnam Money Market Fund generally invests in securities that are rated by at least one nationally recognized rating service in its highest or second-highest categories.

The fund seeks as high a rate of current income as Putnam believes is consistent with liquidity and preservation of principal. As illustrated below, money market fund yields typically rise and fall along with short-term interest rates. Money market funds may not track rates exactly, however, as securities in these funds mature and are replaced with newer instruments earning the most current interest rates.

Whether you want to earmark money for planned near-term expenses or future investment opportunities, or just stow away cash for an unforeseen “rainy day,” Putnam Money Market Fund can be an attractive choice.

An investment in this fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.

Types of money market securities

Money market securities are issued by governments, government agencies, financial institutions, and established non-financial companies. Typically, such instruments have a remaining maturity of 13 months or less. Securities your fund invests in include:

Commercial paper Short-term unsecured loans issued by large corporations, typically for financing accounts receivable and inventories

Bank certificates of deposit Direct obligations of the issuing commercial bank or savings and loan association

Repurchase agreements (repos) Contracts in which one party sells a security to another party and agrees to buy it back later at a specified price; acts in economic terms as a secured loan

Government securities Direct short-term obligations of governments or government agencies; for example, U.S. Treasury bills.

The average yield on money market funds tends to rise and fall with the federal funds rate.

Report from the fund managers

The year in review

For much of Putnam Money Market Fund’s 2007 fiscal year, which ended September 30, 2007, the Federal Reserve (the Fed) held short-term interest rates steady while keeping a sharp eye on inflationary pressures. However, by the summer months, concerns about rising defaults in the subprime mortgage market and a broadening credit crisis, which sharply curtailed financing for consumers and businesses, prompted the Fed to take action. In August, the Fed reduced its discount rate, the rate at which banks can borrow from the Fed. In September, the Fed reduced the federal funds rate, the interest rate banks charge each other for overnight loans needed to maintain reserve levels. Both actions had a positive impact on the market by boosting credit market liquidity. Nevertheless, some money-market-eligible securities suffered during the period. Our conservative style of management helped your fund avoid these investments. Because of our emphasis on safety, the fund’s net asset value remained stable at $1.00 a share during this turbulent period and for the fiscal year as a whole. The fund’s return also surpassed the average for its Lipper peer group for the 12-month period.

Market overview

The crisis in the subprime mortgage lending market and the resulting credit crunch weighed on the performance of many fixed-income sectors — including money market securities — during the year ended September 30, 2007. While the fund did not have any direct exposure to the subprime mortgage market, the subprime crisis caused bond investors to reevaluate risk across the fixed-income market. Yield spreads — which represent the yield premium for investing in bonds that are riskier than U.S. Treasuries, which carry virtually no credit risk — rose dramatically during the period as investors demanded more return on riskier bonds. Consequently, the “risk rally” that persisted in the bond market during the past two years, in which lower-quality issues traded at historically tight yield premiums to U.S. Treasuries and the London Interbank Offered Rate (LIBOR), came to an abrupt end.  Despite the turmoil in the subprime market, money market assets continued to grow. According to iMoneyNet, assets of all money market funds — taxable, institutional, and tax-free — rose to a record $2.835 trillion just following the close of the fiscal year on October 2, 2007.*

Strategy overview

In early 2007, when we foresaw that the problems in the mortgage market might spill over into the money market sector, we began to pay extra attention to structured finance and credit markets — well before the fallout began to dominate headlines in July. By combining our top-down macroeconomic research with strong bottom-up analysis that identifies issuers with the strongest fundamentals and highest credit ratings, we avoided exposing the fund to securities issued by structured investment vehicles (SIVs), complex financial entities that have come under tremendous scrutiny in recent months. We think our extensive review of potential holdings, which goes beyond the research provided by major credit-rating agencies, provides a powerful edge when it comes to selecting securities for your fund.

Given the dramatic widening of credit spreads during August and September and the uncertainty that still remained at the close of the fund’s fiscal year, our primary goal was to preserve the credit integrity of the fund while maintaining liquidity to meet investor redemptions. The fund’s weighted average days to maturity (WAM) fell during the fiscal year, but rose by the end of the period overall. WAM is calculated for all securities in a money market or bond fund. The maturity date is the date that a money market instrument or bond buyer will be repaid by the security’s issuer. The longer the average maturity, the more a fund’s share price will move up or down in response to changes in interest rates. Typically, when we expect the Fed to lower interest rates, as it did on September 18, we would extend the fund’s WAM in the weeks leading up to the anticipated rate cut by purchasing fixed-rate paper with a longer maturity horizon. This may enable us to lock in higher yields that may be available in the market. Due to market volatility during the period, we instituted a barbell strategy, purchasing three-month asset-backed commercial paper (ABCP) multiseller conduits that offered good relative value while also building up a larger liquid position to meet potential redemptions. The portfolio’s WAM was 43 days at the end of the fund’s prior fiscal year, on September 30, 2006. It dropped to 39 days by the end of the fund’s semiannual fiscal period, on March 31, 2007, and rose to 45 days on September 30, 2007. The fund’s 7-day yield rose from 4.93% at the beginning of the fiscal year to 5.12% on September 30, 2007.

Your fund’s holdings

We continue to invest in first-tier corporate and asset-backed commercial paper (ABCP). The ABCP issuers that we consider high-quality investments are backed by trade receivables, commercial loans, student loans, equipment leases, auto loans, mortgage loans, and many other asset types. When screening ABCP for purchase, we focus on four criteria: (1) high-quality diversified assets; (2) appropriate

credit enhancement features; (3) ample liquidity support; and (4) strong management and sponsorship. A good example of an ABCP issuer that meets our stringent criteria is Thunder Bay Funding, a financial entity that is sponsored by Canada’s largest bank, Royal Bank of Canada (RBC). Thunder Bay is backed by a very diversified pool of high-quality assets. This issuer’s credit enhancement includes a commitment from RBC to purchase a portion of Thunder Bay’s assets, which helps offset the risk carried by the assets backing its commercial paper. RBC provides impressive liquidity support, furthermore, as it is required to make funds available to back 100% of Thunder Bay’s issued ABCP if maturing ABCP cannot be repaid by reissuing in the market. We continue to view this type of ABCP structure as a safe and attractive investment.

In contrast, SIVs do not meet our investment criteria, and their securities have never been purchased by the fund. In our opinion, SIVs do not have appropriate structural features that ensure safety of invested principal. For example, we do not believe SIVs have ample alternative liquidity sources as they primarily depend on reissuing debt or liquidating their assets to repay maturing debt. The SIV model has proven to be flawed within the recent volatile credit market. As investors became concerned about the riskiness of SIVs, they have generally stopped repurchasing SIV debt. In the current stressed marketplace, furthermore, SIV managers have found it difficult to sell their underlying assets to repay their commercial paper.

Holdings in Societe Generale and Swedbank are examples of our continued investment in corporate debt issued by large banks. Societe Generale is a diversified French Bank with significant international operations. Swedbank operates primarily as a retail bank in its home country of Sweden.

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

Among the funds in its Money Market Funds category, Lipper ranked Putnam Money Market Fund’s class A shares 44th out of 334, 40th out of 294, and 27th out of 188 funds for the 1-, 5-, and 10-year periods ended September 30, 2007, respectively. These rankings put the fund in the 14th, 14th, and 15th percentile for the same respective periods. The lower the percentile ranking, according to Lipper, the better the fund’s performance relative to its Lipper peers.

Lipper rankings do not reflect sales charges and are based on total return of funds with similar investment styles or objectives as determined by Lipper. Past performance does not guarantee future results.

The outlook for your fund

The following commentary reflects anticipated developments that could affect your fund over the next six months, as well as your management team’s plans for responding to them.

We are encouraged that the liquidity crisis affecting the fixed-income markets is being addressed by the Fed. Many analysts were pleasantly surprised by the amount of the reduction in the federal funds rate, which was cut by half a percentage point. The rate cut helped stabilize the financial markets and restored a level of confidence by demonstrating that the Fed is prepared to step in when extreme events disrupt the bond market’s normal balance of supply and demand.

We think the downturn in the housing market still poses a risk to the broader economy, as well as consumer spending, which is being closely monitored going into the year-end holiday season. If either of these factors causes the nation’s economic growth to slow too much, the Fed may see fit to reduce the federal funds rate again to stimulate growth.

While we expect to see continued volatility in the coming months, the silver lining in any market correction is that many securities may become available at attractive prices. We believe that is now the case in the commercial paper sector. Since we think that some investments in this arena may face challenges in the months ahead, we will be searching for money market securities that may be unfairly tarnished by credit concerns. As always, we will continue to seek to place high-quality issuers and securities in the fund to ensure that its credit quality remains strong and its holdings well diversified.

The views expressed in this report are exclusively those of Putnam Management. They are not meant as investment advice.

Money market funds are not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other governmental agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in this fund.

Current performance may be lower or higher than the quoted past performance, which cannot guarantee future results. None of the share classes carries an initial sales charge. Class B shares reflect the applicable contingent deferred sales charge (CDSC), which is 5% in the first year, declines to 1% in the sixth year, and is eliminated thereafter. Class C shares reflect a 1% CDSC for the first year that is eliminated thereafter. Class A, M, R, and T shares generally have no CDSC. Performance for class B, C, M, R, and T shares before their inception is derived from the historical performance of class A shares, adjusted for the applicable CDSC and higher operating expenses for such shares.

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

Your fund’s expenses

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

Review your fund’s expenses

The table below shows the expenses you would have paid on a $1,000 investment in Putnam Money Market Fund from April 1, 2007, to September 30, 2007. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual returns and expenses.

	Class A	Class B	Class C	Class M	Class R	Class T
Expenses paid per $1,000*	$ 2.74	$ 5.27	$ 5.27	$ 3.50	$ 5.27	$ 4.01
Ending value (after expenses)	$1,024.90	$1,022.30	$1,022.30	$1,024.10	$1,022.30	$1,023.60

* Expenses for each share class are calculated using the fund’s annualized expense ratio for each class, which represents the ongoing expenses as a percentage of average net assets for the six months ended 9/30/07. The expense ratio may differ for each share class (see the last table in this section). Expenses are calculated by multiplying the expense ratio by the average account value for the period; then multiplying the result by the number of days in the period; and then dividing that result by the number of days in the year.

Estimate the expenses you paid

To estimate the ongoing expenses you paid for the six months ended September 30, 2007, use the calculation method below. To find the value of your investment on April 1, 2007, call Putnam at 1-800-225-1581.

Compare expenses using the SEC’s method

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

	Class A	Class B	Class C	Class M	Class R	Class T
Expenses paid per $1,000*	$ 2.74	$ 5.27	$ 5.27	$ 3.50	$ 5.27	$ 4.00
Ending value (after expenses)	$1,022.36	$1,019.85	$1,019.85	$1,021.61	$1,019.85	$1,021.11

* Expenses for each share class are calculated using the fund’s annualized expense ratio for each class, which represents the ongoing expenses as a percentage of average net assets for the six months ended 9/30/07. The expense ratio may differ for each share class (see the last table in this section). Expenses are calculated by multiplying the expense ratio by the average account value for the period; then multiplying the result by the number of days in the period; and then dividing that result by the number of days in the year.

11

Compare expenses using industry averages

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

	Class A	Class B	Class C	Class M	Class R	Class T
Your fund's annualized expense ratio*	0.54%	1.04%	1.04%	0.69%	1.04%	0.79%
Average annualized expense ratio for Lipper peer group†	0.60%	1.10%	1.10%	0.75%	1.10%	0.85%

* For the fund’s most recent fiscal half year; may differ from expense ratios based on one-year data in the financial highlights.

† Putnam is committed to keeping fund expenses below the Lipper peer group average expense ratio and will limit fund expenses if they exceed the Lipper average. The Lipper average is a simple average of funds in the peer group that excludes 12b-1 fees as well as any expense offset and brokerage service arrangements that may reduce fund expenses. To facilitate the comparison in this presentation, Putnam has adjusted the Lipper average to reflect the 12b-1 fees carried by each class of shares other than class A shares, which do not incur 12b-1 fees. Investors should note that the other funds in the peer group may be significantly smaller or larger than the fund, and that an asset-weighted average would likely be lower than the simple average. Also, the fund and Lipper report expense data at different times and for different periods. The fund’s expense ratio shown here is annualized data for the most recent six-month period, while the quarterly updated Lipper average is based on the most recent fiscal year-end data available for the peer group funds as of 9/30/07.

Terms and definitions

Important terms

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

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

Contingent deferred sales charge (CDSC) is generally a charge applied at the time of the redemption of class B or C shares and assumes redemption at the end of the period. Your fund’s class B CDSC declines from a 5% maximum during the first year to 1% during the sixth year. After the sixth year, the CDSC no longer applies. The CDSC for class C shares is 1% for one year after purchase.

Current yield The annual rate of return earned from dividends or interest of an investment. Current yield is expressed as a percentage of the price of a security, fund share, or principal investment.

Share classes

Class A shares generally are fund shares purchased with an initial sales charge. In the case of your fund, which has no sales charge, the reference is to shares purchased or acquired through the exchange of class A shares from another Putnam fund. Exchange of your fund’s class A shares into another fund may involve a sales charge, however.

Class B shares are not subject to an initial sales charge. They may be subject to a CDSC.

Class C shares are not subject to an initial sales charge and are subject to a CDSC only if the shares are redeemed during the first year.

Class M shares have a lower initial sales charge and a higher 12b-1 fee than class A shares and no CDSC. In the case of your fund, which has no sales charge, the reference is to shares purchased or acquired through the exchange of class M shares from another Putnam fund. Exchange of your fund’s class M shares into another fund may involve a sales charge, however.

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

Class T shares are not subject to an initial sales charge or CDSC (except on certain redemptions of shares bought without an initial sales charge); however, they are subject to a 12b-1 fee.

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 with Putnam Investment Management (“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 2007, the Contract Committee met several 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. The Contract Committee recommended, and the Independent Trustees approved, the continuance of your fund’s management contract, effective July 1, 2007.

In addition, in anticipation of the sale of Putnam Investments to Great-West Lifeco, at a series of meetings ending in March 2007, the Trustees reviewed and approved new management and distribution arrangements to take effect upon the change of control. Shareholders of all funds approved the management contracts in May 2007, and the change of control transaction was completed on August 3, 2007. Upon the change of control, the management contracts that were approved by the Trustees in June 2007 automatically terminated and were replaced by new contracts that had been approved by shareholders. In connection with their review for the June 2007 continuance of the Putnam funds’ management contracts, the Trustees did not identify any facts or circumstances that would alter the substance of the conclusions and recommendations they made in their review of the contracts to take effect upon the change of control.

The Independent Trustees’ approval was based on the following conclusions:

• That the fee schedule in effect for your fund 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 this 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 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 responsibilities, 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 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 34th percentile in management fees and in the 14th percentile in total expenses (less any applicable 12b-1 fees) as of December 31, 2006 (the first percentile being the least expensive funds and the 100th percentile being the most

15

expensive funds). (Because the fund’s custom peer group is smaller than the fund’s broad Lipper Inc. peer group, this expense information may differ from the Lipper peer expense information found elsewhere in this report.) The Trustees noted that expense ratios for a number of Putnam funds, which show the percentage of fund assets used to pay for management and administrative services, distribution (12b-1) fees and other expenses, had been increasing recently as a result of declining net assets and the natural operation of fee breakpoints.

The Trustees noted that the expense ratio increases described above were currently being controlled by expense limitations implemented in January 2004 and which Putnam Management had committed to maintain at least through 2007. In anticipation of the change of control of Putnam Investments, the Trustees requested, and received a commitment from Putnam Management and Great-West Lifeco, to extend this program through at least June 30, 2009. These expense limitations give effect to a commitment by Putnam Management that the expense ratio of each open-end fund would be no higher than the average expense ratio of the competitive funds included in the fund’s relevant Lipper universe (exclusive of any applicable 12b-1 charges in each case). The Trustees observed that this commitment to limit fund expenses has served shareholders well since its inception.

In order to ensure that the expenses of the Putnam funds continue to meet evolving competitive standards, the Trustees requested, and Putnam Management agreed, to extend for the twelve months beginning July 1, 2007, an additional expense limitation for certain funds at an amount equal to the average expense ratio (exclusive of 12b-1 charges) of a custom peer group of competitive funds selected by Lipper to correspond to the size of the fund. This additional expense limitation will be applied to those open-end funds that had above-average expense ratios (exclusive of 12b-1 charges) based on the custom peer group data for the period ended December 31, 2006. This additional expense limitation will not be applied to your fund because it had a below-average expense ratio relative to its custom peer group.

• Economies of scale. Your fund currently has the benefit of breakpoints in its management fee that provide shareholders with significant economies of scale, which means that the effective management fee rate of a fund (as a percentage of fund assets) declines as a fund grows in size and crosses specified asset thresholds. Conversely, as a fund shrinks in size — as has been the case for many Putnam funds in recent years — these breakpoints result in increasing fee levels. In recent years, the Trustees have examined the operation of the existing breakpoint structure during periods of both growth and decline in asset levels. 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 assets, and to consider the 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.

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 had met 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 recognized 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.

16

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 class A share cumulative total return performance at net asset value was in the following percentiles of its Lipper Inc. peer group (Lipper Money Market Funds) for the one-, three- and five-year periods ended March 31, 2007 (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
13th	13th	15th

(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, 2007, there were 340, 323, and 293 funds, respectively, in your fund’s Lipper peer group.* Past performance is no guarantee of future returns.)

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 intent to 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 its distributor’s contract and distribution plan with Putnam Retail Management Limited Partnership and the custodian agreement and investor servicing agreement with Putnam Fiduciary Trust Company (“PFTC”), each of which provides benefits to affiliates of Putnam Management. In the case of the custodian agreement, the Trustees considered that, effective January 1, 2007, the Putnam funds had engaged State Street Bank and Trust Company as custodian and began to transition the responsibility for providing custody services away from PFTC.

* The percentile rankings for your fund’s class A share annualized total return performance in the Lipper Money Market Funds category for the one-, five- and ten-year periods ended September 30, 2007 were 14%, 14%, and 15%, respectively. Over the one-, five- and ten-year periods ended September 30, 2007, the fund ranked 44th out of 334, 40th out of 294, and 27th out of 188 funds, respectively. Note that this more recent information was not available when the Trustees approved the continuance of your fund’s management contract.

17

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.

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 non-investment assets are added together. Any unpaid expenses and other liabilities are subtracted from this total. The result is divided by the number of shares to determine the net asset value per share, which is calculated separately for each class of shares. (For funds with preferred shares, the amount subtracted from total assets includes the 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 Money Market Fund:

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 Money Market Fund (the “fund”) at September 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 September 30, 2007 by correspondence with the custodian and brokers provide a reasonable basis for our opinion.

Notes to financial statements 9/30/07

Note 1: Significant accounting policies

Putnam Money Market Fund (the “fund”), a Massachusetts business trust, is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The fund seeks to provide as high a rate of current income as Putnam Investment Management, LLC (“Putnam Management”), the fund’s manager, a wholly-owned subsidiary of Putnam, LLC, believes is consistent with preservation of capital and maintenance of liquidity by investing in a diversified portfolio of high-quality short-term debt obligations. The fund may invest up to 100% of its assets in money market instruments from the banking, the personal credit and the business credit industries.

The fund offers class A, class B, class C, class M, class R and class T shares. Each class of shares is sold without a front-end sales charge. Class A, class M, class R and class T shares also are generally not subject to a contingent deferred sales charge. In addition to the standard offering of class A shares, they are also sold to certain college savings plans and other Putnam funds. Class B shares convert to class A shares after approximately eight years and are subject to a contingent deferred sales charge, if those shares are redeemed within six years of purchase. Class C shares have a one-year 1.00% contingent deferred sales charge and do not convert to class A shares. Class R shares are offered to qualified employee-benefit plans. The expenses for class A, class B, class C, class M, class R and class T shares may differ based on each class’ distribution fee, which is identified in Note 2.

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

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 The valuation of the fund’s portfolio instruments is determined by means of the amortized cost method (which approximates market value) as set forth in Rule 2a-7 under the Investment Company Act of 1940. The amortized cost of an instrument is determined by valuing it at its original cost and thereafter amortizing any discount or premium from its face value at a constant rate until maturity.

B) Joint trading account Pursuant to an exemptive order from the Securities and Exchange Commission (the “SEC”), the fund may transfer uninvested cash balances into a joint trading account along with the cash of other registered investment companies and certain other accounts managed by Putnam Management. These balances may be invested in issues of high-grade short-term investments having maturities of up to 90 days.

C) Repurchase agreements The fund, or any joint trading account, through its custodian, receives delivery of the underlying securities, the market value of which at the time of purchase is required to be in an amount at least equal to the resale price, including accrued interest. Collateral for certain tri-party repurchase agreements is held at the counterparty’s custodian in a segregated account for the benefit of the fund and the counterparty. Putnam Management is responsible for determining that the value of these underlying securities is at all times at least equal to the resale price, including accrued interest.

D) Security transactions and related investment income Security transactions are recorded on the trade date (the date the order to buy or sell is executed). Interest income is recorded on the accrual basis. Premiums and discounts from purchases of short-term investments are amortized/accreted at a constant rate until maturity. Gains or losses on securities sold are determined on the identified cost basis.

E) Federal taxes It is the policy of the fund to distribute all of its taxable income within the prescribed time and otherwise comply with the provisions of the Internal Revenue Code of 1986 (the “Code”) applicable to regulated investment companies. It is also the intention of the fund to distribute an amount sufficient to avoid imposition of any excise tax under Section 4982 of the Code, as amended. Therefore, no provision has been made for federal taxes on income, capital gains or unrealized appreciation on securities held nor for excise tax on income and capital gains.

Pursuant to federal income tax regulations applicable to regulated investment companies, the fund has elected to defer to its fiscal year ending September 30, 2008 $39,633 of losses recognized during the period November 1, 2006 t0 September 30, 2007.

F) Distributions to shareholders Income dividends are recorded daily by the fund and are paid monthly. Distributions from capital gains, if any, are paid at least annually. The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. For the year ended September 30, 2007, there were no temporary or permanent differences. Reclassifications are made to the fund’s capital accounts to reflect income and gains available for distribution (or available capital loss carryovers) under income tax regulations. For the year ended September 30, 2007, the fund reclassified $81,526 to decrease distributions in excess of net investment income and $81,526 to decrease paid-in-capital.

The tax basis components of distributable earnings as of September 30, 2007 were as follows:

Post-October loss                                                                                          $(39,633)

The aggregate identified cost on a financial reporting and tax basis is the same.

Note 2: Management fee, administrative services and other transactions

Putnam Management is paid for management and investment advisory services quarterly based on the average net assets of the fund. Such fee is based on the following annual rates: 0.50% of the first $100 million of average net assets, 0.40% of the next $100 million, 0.35% of the next $300 million, 0.325% of the next $500 million, 0.30% of the next $500 million, 0.275% of the next $2.5 billion, 0.25% of the next $2.5 billion, 0.225% of the next $5 billion, 0.205% of the next $5 billion, 0.19% of the next $5 billion and 0.18% thereafter.

Putnam Management has agreed to waive fees and reimburse expenses of the fund through June 30, 2009 to the extent necessary to ensure that the fund’s expenses do not exceed the simple average of the expenses of all funds viewed by Lipper Inc. as having the same investment classification or objective as the fund. The expense reimbursement is based on a comparison of the fund’s expenses with the average annualized operating expenses of the funds in its Lipper peer group for each calendar quarter during the fund’s last fiscal year, excluding 12b-1 fees and without giving effect to any expense offset and brokerage service arrangements that may reduce fund expenses. For the year ended September 30, 2007, Putnam Management did not waive any of its management fee from the fund.

Effective August 3, 2007, Marsh & McLennan Companies, Inc. sold its ownership interest in Putnam Management, its parent companies and affiliates to a wholly-owned subsidiary of Great-West Lifeco, Inc. The fund's shareholders have approved a new management contract for the fund that became effective upon the sale.

For the year ended September 30, 2007, Putnam Management has assumed $1,969 of legal, shareholder servicing and communication, audit and Trustee fees incurred by the fund in connection with certain legal and regulatory matters (including those described in Note 6).

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

Custodial services for the fund’s assets were provided by Putnam Fiduciary Trust Company (“PFTC”), an affiliate of Putnam Management, and by State Street Bank and Trust Company (“State Street”). Custody fees are based on the fund’s asset level, the number of its security holdings, transaction volumes and with respect to PFTC, certain fees related to the transition of assets to State Street. Putnam Investor Services, a division of PFTC, provided investor servicing agent functions to the fund. Putnam Investor Services received fees for investor servicing, subject to certain limitations, based on the number of shareholder accounts in the fund and the level of defined contribution plan assets in the fund. During the year ended September 30, 2007, the fund incurred $7,082,942 for custody and investor servicing agent functions provided by PFTC.

The fund has entered into arrangements with PFTC and State Street whereby PFTC’s and State Street’s fees are reduced by credits allowed on cash balances. For the year ended September 30, 2007, the fund’s expenses were reduced by $512,837 under these arrangements. In addition, the fund’s expenses were adjusted by the reallocation to other Putnam funds of $1,074,142 of balance credits, which had been incorrectly allocated to the fund between November 2003 and December 2006.

Each independent Trustee of the fund receives an annual Trustee fee, of which $902, 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 and industry seminars and for certain compliance-related matters. Trustees also are reimbursed for expenses they incur relating to their services as Trustees. 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.

The fund has adopted distribution plans (the “Plans”) with respect to its class B, class C, class M, class R and class T shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The purpose of the Plans is to compensate Putnam Retail Management, a wholly-owned subsidiary of Putnam, LLC and Putnam Retail Management GP, Inc., for services provided and expenses incurred in distributing shares of the fund. The Plans provide for payments by the fund to Putnam Retail Management at an annual rate of up to 0.75%, 1.00%, 1.00%, 1.00% and 0.35% of the average net assets attributable to class B, class C, class M, class R and class T shares, respectively. The Trustees have approved payment by the fund at an annual rate of 0.50%, 0.50%, 0.15%, 0.50% and 0.25% of the average net assets attributable to class B, class C, class M, class R and class T shares, respectively.

For the year ended September 30, 2007, Putnam Retail Management, acting as underwriter, received net commissions of $326,107 and $6,415 in contingent deferred sales charges from redemptions of class B and class C shares, respectively.

A deferred sales charge of up to 1.00% for class A and class T shares and up to 0.15% for class M shares may be assessed on certain redemptions. For the year ended September 30, 2007, Putnam Retail Management, acting as underwriter, received no monies in contingent deferred sales charges from redemptions of class A, class M or class T shares acquired through an exchange from another fund.

Note 3: Purchases and sales of securities

During the year ended September 30, 2007, cost of purchases and proceeds from sales (including maturities) of investment securities (all short-term obligations) aggregated $17,264,710,817 and $17,055,937,459, respectively.

Note 5: Investment in Putnam Prime Money Market Fund

The fund invests in Putnam Prime Money Market Fund, an open-end management investment company managed by Putnam Management. Investments in Putnam Prime Money Market Fund are valued at its closing net asset value each business day. Management fees paid by the fund are reduced by an amount equal to the management and administrative services fees paid by Putnam Prime Money Market Fund with respect to assets invested by the fund in Putnam Prime Money Market Fund. For the year ended September 30, 2007, management fees paid were reduced by $101,635 relating to the fund's investment in Putnam Prime Money Market Fund. Income distributions earned by the fund are recorded as income in the Statement of operations and totaled $6,240,905 for the year ended September 30, 2007.

Note 6: Regulatory matters and litigation

In late 2003 and 2004, Putnam Management settled charges brought by the SEC and the Massachusetts Securities Division in connection with excessive short-term trading in Putnam funds. Payments from Putnam Management will be distributed to certain open-end Putnam funds and their shareholders. These allegations and related matters have served as the general basis for certain lawsuits, including purported class action lawsuits against Putnam Management and, in a limited number of cases, 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 pronouncements

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 is not expected to have a material effect on the fund's financial statements. However, the conclusions regarding the Interpretation may be subject to review and adjustment at a later date based on factors including, but not limited to, further implementation guidance expected from the FASB, and on-going analysis of tax laws, regulations and interpretations thereof.

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.

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) In August 2007, the Code of Ethics of Putnam Investment Management, LLC was amended to reflect the change in ownership of Putnam Investments Trust, the parent company of Putnam Investment Management, LLC, from Marsh & McLennan Companies, Inc. (“MMC”) to Great-West Lifeco Inc., a subsidiary of Power Financial Corporation. In addition to administrative and non-substantive changes, the Code of Ethics was amended to remove a prohibition, which applied to members of Putnam Investments’ Executive Board and senior members of the staff of the Chief Financial Officer of Putnam Investments, on transactions in MMC securities during the period between the end of a calendar quarter and the public announcement of MMC’s earnings for that quarter.

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, Mr. Hill and Mr. Darretta 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
September 30, 2007	$119,165	$352	$3,274	$1,123*
September 30, 2006	$91,511*	$877	$2,415	$1,970

* Includes fees of $823 and $2,985 billed by the fund’s independent auditor to the fund for procedures necessitated by regulatory and litigation matters for the fiscal years ended September

30, 2007 and September 30, 2006, respectively. These fees were reimbursed to the fund by Putnam Investment Management, LLC (“Putnam Management”).

For the fiscal years ended September 30, 2007and September 30, 2006, the fund’s independent auditor billed aggregate non-audit fees in the amounts of $107,956 and $286,942 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.
