What makes Putnam different?

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.

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

We have below-average expenses and stringent investor protections, and provide a wealth of information about the Putnam funds.

Industry-leading service

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

Message from the Trustees

Dear Fellow Shareholder

Over the last three months of your fund’s reporting period, investors were particularly preoccupied with the course of the economy. Beginning in May, a more pessimistic outlook pervaded the markets as leading economic indicators began to warn of slower growth and the Federal Reserve (the Fed) continued its series of interest-rate increases. The resulting correction undercut much of the progress that markets had achieved in the previous three months of the period.

However, we believe that today’s higher interest rates, far from being a threat to global economic fundamentals, are in fact an integral part of them. Economic growth may, indeed, be slowing somewhat as a result of the higher rates, but we consider this a typical development for the middle of an economic cycle, and one that could help provide the basis for a longer and more durable business expansion and a continued healthy investment environment. The recent correction brought valuations back to attractive levels, creating opportunities in a wide array of markets and sectors. Furthermore, since the Fed paused in its tightening cycle shortly after the close of the reporting period, the market atmosphere has gradually become more optimistic. Putnam Investments’ management team, under the leadership of Chief Executive Officer Ed Haldeman, continues to focus on investment performance, and the investment professionals managing your fund have been working to take advantage of the opportunities presented by this environment.

We would like to take this opportunity to announce the retirement of one of your fund’s Trustees, John Mullin, an independent Trustee of the Putnam funds since 1997. We thank him for his service.

In the following pages, members of your fund’s management team discuss the fund’s performance and strategies for the fiscal period ended July 31, 2006, and provide their outlook for the months ahead. As always, we thank you for your support of the Putnam funds.

Putnam Voyager Fund: seeking growth
for investors for over 35 years

In 1969, when Putnam Voyager Fund made its debut, Richard M. Nixon became the 37th U.S. President and Americans landed on the moon for the first time. For the U.S. financial markets, it was the eve of a sluggish decade in which the Dow Jones Industrial Average would gain only 4.8% . Despite Vietnam War tensions and worries over inflation and recession, the fund’s first management team was ready to tap into the long-term growth potential of American businesses.

“The basic qualities underlying the dynamism of our economy are not at issue here,” said the first report to shareholders in 1969. “The future has never been brighter.” The report also discussed the risk of “underestimating the potential growth of companies with strong fundamental trends.”

In the 35 years since its first report was published, the fund has witnessed many more difficult markets, as well as unprecedented stock market growth and extraordinary innovation. One emerging growth trend was noted in the fund’s 1988 annual report: “Several years from now, when you’re leaving home … you may find yourself tossing something new into your tote bag or briefcase — your phone. That’s right: the era of truly portable telephones is dawning.”

Today, the fund continues to look for promising growth trends as well as companies

Putnam Voyager Fund seeks capital appreciation by investing mainly in stocks of U.S. companies believed by Putnam Management to offer above-average growth potential. The fund invests mainly in a diversified portfolio of large and midsize companies across a range of industries, although the fund may invest in companies of any size. The fund targets companies with sales and profits that Putnam believes are likely to grow faster than the overall economy. The fund may be appropriate for investors seeking growth of capital and broad exposure to growth-oriented companies.

Report from the fund managers

The year in review

In the closing months of Putnam Voyager Fund’s fiscal year, the stock market’s advance turned into a retreat. Investors demonstrated concern regarding slowing economic growth and stronger inflationary pressures. The year was difficult for the fund, which trailed its benchmark and ranked below the average result of other funds in its Lipper peer group, based on results at net asset value (NAV, without sales charges). The market favored value-style stocks, which outperformed growth-style stocks by approximately 12 percentage points in the period. Despite being positioned with a significant overweight to the strong financial and energy sectors, the fund struggled as the investment team’s stock selections within the technology and consumer sectors caused underperformance.

Market overview

The U.S. economy expanded throughout the fiscal year in the face of a variety of obstacles. Early in the period, Hurricane Katrina devastated the U.S. Gulf Coast, and put sustained upward pressure on energy prices by knocking out production and refining capacity. Other challenges to the economy included the global outbreak of avian flu, a slowing in the housing sector, and ongoing geopolitical turmoil in the Middle East. However, growth was resilient in the face of both actual and anticipated calamities. In our assessment, the cumulative effect of interest-rate increases by the U.S. Federal Reserve Board (Fed) over the past two years proved to be a bigger factor in slowing the economy. Investors patiently waited for the Fed to pause in its program of rate increases, but this did not occur until after the end of the fiscal period.

It was a particularly difficult period for large-cap growth stocks, as the Russell 1000 Value Index outperformed the Russell 1000 Growth Index by a wide margin. These results stand in contrast to the strong corporate earnings results that growth stocks delivered, and seemed to reflect a certain aversion toward stocks with higher price multiples, in spite of their strong business performance. In terms of sectors, utility and energy stocks were top performers during the year, as their stable earnings outlook,

improving company fundamentals, and dividend yields proved attractive to investors uncertain about the economy. Stocks in the consumer sector were weak as investors looked ahead to a drop-off in consumer spending, considered likely because of rising energy prices and adjustable-rate mortgage payments. Similarly, stocks in the technology sector declined in the final months of the year as jittery investors reacted to the outlook for technology spending, even as many companies in the sector continued to report strong earnings.

Strategy overview

As growth investors, we believe that market participants consistently underestimate the sustainability of growth and returns on capital that is achievable by companies with unique and powerful competitive advantages. This is the market inefficiency we are attempting to exploit. At each step of our process, we combine quantitative and fundamental research. Our quantitative models examine historical data to assess the strength, quality, and sustainability of earnings growth in the companies we follow and to determine the relative attractiveness of company valuations. Our fundamental analysts study industries and businesses, looking toward the future to forecast the potential growth of cash flows for each company. With these forecasts, we produce a range of possible outcomes for each company we evaluate.

Market sector performance

These indexes provide an overview of performance in different market sectors for the 12 months ended 7/31/06.

Equities
Russell 1000 Growth Index (large-company growth stocks)	–0.76%

Russell 1000 Value Index (large-company value stocks)	11.59%

During the annual period, the fund was well diversified across a number of different sectors. The portfolio had modest overweight positions (relative to the fund’s benchmark, the Russell 1000 Growth Index) in traditional growth sectors of the stock market such as technology and health care, as well as in the financial and energy sectors. However, in the latter two sectors, we hold relatively fewer companies, each with what we believe to be strong long-term growth potential. In the financial sector, our research identified several stocks with business models that we believe may deliver strong earnings growth for a sustained period.

Your fund’s holdings

During the period, several holdings within the financial sector had a positive impact on performance. Our significant overweight to the investment banking and brokerage industry proved beneficial, particularly the fund’s position in Bear Stearns stock. Successful holdings in the banking industry, including Commerce Bancorp, as well as more diversified financial service companies Countrywide Financial and Wells Fargo, also helped. These and other stocks gained value during the period, responding to analysts’ bullish outlooks, which in turn reflected vigorous capital-markets activity and potential for international growth. Banks also were boosted by speculation that the Fed was nearing the end of its cycle of interest-rate

hikes. Shares of Countrywide Financial, in particular, rose. This giant mortgage-lender continues to beat analysts’ estimates despite interest-rate pressures.

Fund holdings in the energy sector also proved rewarding. Marathon Oil Company, an integrated oil company with operations in producing and refining oil and distributing petroleum products, was among the top contributors. Valero Energy, which focuses on refining oil, also performed well. High oil prices continue to drive the strong results in these industries and oil demand remains robust. This trend shows no signs of slowing down anytime soon and these companies are on track to report strong earning growth in the upcoming months. Marathon Oil and Valero also benefited from superior production capabilities.

Although the primary detractors from performance included technology holdings, we remain committed to our positions in the sector. With regard to eBay, we believe investor concerns about near-term growth are overdone. Given our expectations for continued strength in Internet-based commerce and advertising, we think the market is underestimating the ability of this company to achieve attractive long-term growth and capital returns. Though Dell, another technology holding, was hurt by its poor service and reliance on Intel’s less competitive microprocessors, we believe that the company still has a strong business model. In our opinion, the market has over-penalized Dell and at

recent valuations, the stock is reflecting unduly pessimistic growth assumptions.

Fund holding Yahoo! met its earnings expectations but failed to launch its much-promised new search product on time. The postponement of this launch until 2007 has given competitor Google more time to build its lead. Despite this short-term problem, Yahoo!’s core branded advertising business continues to grow strongly, and the company dominates this area. We believe Yahoo! will eventually have a competitive search product in the marketplace and that online advertising is still in its infancy. The fund holds positions in both Yahoo! and Google, and we consider the prospects of both stocks attractive. A brighter spot in the technology sector was the fund’s significant overweight to Apple. This contributed to performance as the company continued to benefit from dramatic growth in iPod sales, gained market share with its new Intel-based Mac computers, and achieved increased success in its retail stores.

Within consumer staples, our position in cosmetic manufacturer Avon detracted from results as the company faced weakness in its operations in China and Eastern Europe as well as continued competitive pressure in the U.S. market. Our overweight to Apollo Group, the for-profit education provider, also hindered results in this sector as management’s reduced earnings outlook heightened near-term concerns among market participants. We decided to eliminate the fund’s positions in these stocks because of their deteriorating outlook.

Positions within consumer cyclicals also hurt relative performance. In particular, the homebuilder NVR, retailer The Home Depot, and broadcaster XM Satellite had disappointing price performance. Despite reporting an increase in first-quarter profit, NVR saw its stock price decline after it cautioned that its margins might be squeezed by higher material costs and slowing housing markets. The Home Depot also achieved higher profits during the first quarter, but relatively weak sales totals and concerns about the outlook for consumer spending punished the stock. XM Satellite also retreated as the firm trimmed its 2006 forecast for new subscribers, citing a slump in demand and the slow rollout of new products. We continue to hold positions in all three stocks. Fortunately, the fund’s overweight position in casino and hotel operator Las Vegas Sands, which was another strong performer during the period, offset some of the damage in the consumer cyclicals sector. This company continued its upward climb as investors reacted favorably to positive analyst reports and the company’s strong results. Furthermore, plans by the gaming industry to turn the Chinese city of Macau into a Las Vegas-style destination are expected to progress steadily, and we believe the company is well positioned to take advantage of this growth opportunity.

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.

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.

Over the next several months, Putnam’s asset-allocation specialists anticipate that returns from U.S. stocks will be more competitive with those of international markets, based on the robust health of the U.S. corporate sector. The odds of solid relative performance seem particularly good for companies with attractive growth and profitability characteristics but below-market valuations. The team expects that as investors come to discover and reward the profitability of large companies, and as the pace of equity-market appreciation moderates, U.S. market leadership will likely shift toward larger-cap, growth-oriented issues.

Currently, as a result of stock selection decisions, the portfolio’s largest overweight is in the finan-cial sector, which also includes many of the fund’s largest overweight positions in individual stocks relative to the benchmark. Other sectors that are overweight relative to the benchmark are consumer cyclicals and technology sectors. The fund also has a modest overweight to the energy sector. Due to lackluster growth prospects and poor valuation in the consumer staples and conglomerates sectors, the fund has underweight positions in both of them. It has no positions within the basic materials sector.

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

The fund invests some or all of its assets in small and/or midsize companies. Such investments increase the risk of fluctuations in the value of your investment. Growth investing targets companies with above-average earnings that may be subject to price volatility if earnings expectations are not met.

Performance assumes reinvestment of distributions and does not account for taxes. Returns at public offering price (POP) for class A and M shares reflect a sales charge of 5.25% and 3.25%, respectively. Class B share returns reflect the applicable contingent deferred sales charge (CDSC), which is 5% in the first year, declining to 1% in the sixth year, and is eliminated thereafter. Class C shares reflect a 1% CDSC the first year that is eliminated thereafter. Class R and Y shares have no initial sales charge or CDSC. Performance for class B, C, M, R, and Y shares before their inception is derived from the historical performance of class A shares, adjusted for the applicable sales charge (or CDSC) and, except for class Y shares, the higher operating expenses for such shares.

Your fund’s expenses

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

Review your fund’s expenses

The table below shows the expenses you would have paid on a $1,000 investment in Putnam Voyager Fund from February 1, 2006, to July 31, 2006. 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 Y

Expenses paid per $1,000*	$ 5.28	$ 8.84	$ 8.84	$ 7.65	$ 6.47	$ 4.09

Ending value (after expenses)	$918.90	$916.30	$916.10	$916.90	$918.40	$920.30

* Expenses for each share class are calculated using the fund’s annualized expense ratio for each class, which represents the ongoing expenses as a percentage of net assets for the six months ended 7/31/06. The expense ratio may differ for each share class (see the table at the bottom of the next page). Expenses are calculated by multiplying the expense ratio by the average account value for the period; then multiplying the result by the number of days in the period; and then dividing that result by the number of days in the year. Does not reflect the effect of a non-recurring reimbursement by Putnam. If this amount had been reflected in the table above, expenses for each share class would have been lower.

Estimate the expenses you paid

To estimate the ongoing expenses you paid for the six months ended July 31, 2006, use the calculation method below. To find the value of your investment on February 1, 2006, go to www.putnam.com and log on to your account. Click on the “Transaction History” tab in your Daily Statement and enter 02/01/2006 in both the “from” and “to” fields. Alternatively, 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.

* Expenses for each share class are calculated using the fund’s annualized expense ratio for each class, which represents the ongoing expenses as a percentage of net assets for the six months ended 7/31/06. The expense ratio may differ for each share class (see the table at the bottom of this page). Expenses are calculated by multiplying the expense ratio by the average account value for the period; then multiplying the result by the number of days in the period; and then dividing that result by the number of days in the year. Does not reflect the effect of a non-recurring reimbursement by Putnam. If this amount had been reflected in the table above, expenses for each share class would have been lower.

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 net assets have been used to pay ongoing expenses during the period.

	Class A	Class B	Class C	Class M	Class R	Class Y

Your fund’s annualized
expense ratio*	1.11%	1.86%	1.86%	1.61%	1.36%	0.86%

* For the fund’s most recent fiscal half year; may differ from expense ratios based on one-year data in the financial highlights. Does not reflect the effect of a non-recurring reimbursement by Putnam. If this amount had been reflected in the table above, the expense ratio for each share class would have been lower.

† Simple average of the expenses of all front-end load funds in the fund’s Lipper peer group, calculated in accordance with Lipper’s standard method for comparing fund expenses (excluding 12b-1 fees and without giving effect to any expense offset and brokerage service arrangements that may reduce fund expenses). This average reflects each fund’s expenses for its most recent fiscal year available to Lipper as of 6/30/06. To facilitate comparison, Putnam has adjusted this average to reflect the 12b-1 fees carried by each class of shares other than class Y shares, which do not incur 12b-1 fees. The peer group may include funds that are significantly smaller or larger than the fund, which may limit the comparability of the fund’s expenses to the simple average, which typically is higher than the asset-weighted average.

Your fund’s
portfolio turnover

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

Turnover data for the fund is calculated based on the fund’s fiscal-year period, which ends on July 31. Turnover data for the fund’s Lipper category is calculated based on the average of the turnover of each fund in the category for its fiscal year ended during the indicated year. Fiscal years vary across funds in the Lipper category, which may limit the comparability of the fund’s portfolio turnover rate to the Lipper average. Comparative data for 2006 is based on information available as of 7/31/06.

Your fund’s risk

This risk comparison is designed to help you understand how your fund compares with other funds. The comparison utilizes a risk measure developed by Morningstar, an independent fund-rating agency. This risk measure is referred to as the fund’s Overall Morningstar Risk.

Your fund’s Overall Morningstar^®Risk

Your fund’s Overall Morningstar Risk is shown alongside that of the average fund in its broad asset class, as determined by Morningstar. The risk bar broadens the comparison by translating the fund’s Overall Morningstar Risk into a percentile, which is based on the fund’s ranking among all funds rated by Morningstar as of June 30, 2006. A higher Overall Morningstar Risk generally indicates that a fund’s monthly returns have varied more widely.

Morningstar determines a fund’s Overall Morningstar Risk by assessing variations in the fund’s monthly returns — with an emphasis on downside variations — over 3-, 5-, and 10-year periods, if available. Those measures are weighted and averaged to produce the fund’s Overall Morningstar Risk. The information shown is provided for the fund’s class A shares only; information for other classes may vary. Overall Morningstar Risk is based on historical data and does not indicate future results. Morningstar does not purport to measure the risk associated with a current investment in a fund, either on an absolute basis or on a relative basis. Low Overall Morningstar Risk does not mean that you cannot lose money on an investment in a fund. Copyright 2006 Morningstar, Inc. All Rights Reserved.

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.

Public offering price (POP) is the price of a mutual fund share plus the maximum sales charge levied at the time of purchase. POP performance figures shown here assume the 5.25% maximum sales charge for class A shares and 3.25% for class M shares.

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.

Share classes

Class A shares are generally subject to an initial sales charge and no CDSC (except on certain redemptions of shares bought without an initial sales charge).

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 (except on certain redemptions of shares bought without an initial sales charge).

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

Class Y shares are not subject to an initial sales charge or CDSC, and carry no 12b-1 fee. They are only available to eligible purchasers, including eligible defined contribution plans or corporate IRAs.

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 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, effective July 1, 2006.

This approval was based on the following conclusions:

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

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

These conclusions were based on a comprehensive consideration of all information provided to the Trustees and were not the result of any single factor. Some of the factors that figured particularly in the Trustees’ deliberations 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 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 14th percentile in management fees and in the 17th percentile in total expenses (less any applicable 12b-1 fees) as of December 31, 2005 (the first percentile being the least expensive funds and the 100th percentile being the most expensive funds). 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, in consultation with the Contract Committee, has committed to maintain at least through 2007. 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 implement an additional expense limitation for certain funds for the twelve months beginning January 1, 2007 equal to the average expense ratio (exclusive of 12b-1 charges) of a custom peer group of competitive funds selected by Lipper based on 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 Lipper custom peer group data for the period ended December 31, 2005. This additional expense limitation will not be applied to your fund.

* 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, 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 Committee 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 underperfor-mance 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 Large-Cap Growth Funds) 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

64	78	69

(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 694, 593, and 479 funds, respectively, in your fund’s Lipper peer group.* Past performance is no guarantee of future performance.)

The Trustees noted the disappointing performance for your fund for the three-year period ended March 31, 2006. In this regard, the Trustees considered that Putnam Management had made changes to the fund’s investment team that it believed would strengthen the investment process by focusing on a blending of quantitative techniques with fundamental analysis.

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

* The percentile rankings for your fund’s class A share annualized total return performance in the Lipper Large-Cap Growth Funds category for the one-, five- and ten-year periods ended June 30, 2006 , were 76%, 75%, and 74%, respectively. Over the one-, five- and ten-year periods ended June 30, 2006, the fund ranked 536 out of 705, 358 out of 482, and 123 out of 167 funds, respectively. Note that this more recent information was not available when the Trustees approved the continuance of your fund’s management contract.

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, all of 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 mutual funds are by no means uniform when examined by individual asset sectors, suggesting that differences in the pricing of investment management services to these types of clients 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 mutual 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

A guide to 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, 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 Voyager 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 Voyager Fund (the “fund”) at July 31, 2006, 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 July 31, 2006, by correspondence with the custodian, provide a reasonable basis for our opinion.

Notes to financial statements 7/31/06

Note 1: Significant accounting policies

Putnam Voyager 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 invests mainly in common stocks of U.S. companies, with a focus on growth stocks.

The fund offers class A, class B, class C, class M, class R and class Y shares. Class A and class M shares are sold with a maximum front-end sales charge of 5.25% and 3.25%, respectively, and generally do not pay a contingent deferred sales charge. Class B shares, which convert to class A shares after approximately eight years, do not pay a front-end sales charge and are subject to a contingent deferred sales charge, if those shares are redeemed within six years of purchase. Class C shares have a one-year 1.00% contingent deferred sales charge and do not convert to class A shares. Class R shares, which are offered to qualified employee-benefit plans, are sold without a front-end sales charge or a contingent deferred sales charge. The expenses for class A, class B, class C, class M and class R shares may differ based on the distribution fee of each class, which is identified in Note 2. Class Y shares, which are sold at net asset value, are generally subject to the same expenses as class A, class B, class C, class M and class R shares, but do not bear a distribution fee. Class Y shares are sold to certain eligible purchasers including certain defined contribution plans (including corporate IRAs), bank trust departments, trust companies and other Putnam funds and products, and certain college savings plans.

A 2.00% redemption fee may apply to any shares that are redeemed (either by selling or exchanging into another fund) within 5 days of purchase. The redemption fee is accounted for as an addition to paid-in-capital.

The redemption fee discussed above will be replaced, effective October 2, 2006, by a 1.00% redemption fee on any shares purchased on or after such date that are redeemed (either by selling or exchanging into another fund) within 7 days of purchase.

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

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 Investments for which market quotations are readily available are valued at the last reported sales price on their principal exchange, or official closing price for certain markets. If no sales are reported — as in the case of some securities traded over-the-counter — a security is valued at its last reported bid price.

Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange and therefore the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. Accordingly, on certain days, the fund will fair value foreign equity securities taking into account multiple factors, including movements in the U.S. securities markets. The number of days on which fair value prices will be used will depend on market activity and it is possible that fair value prices will be used by the fund to a significant extent. Securities quoted in foreign currencies, if any, are translated into U.S. dollars at the current exchange rate. Other investments, including certain restricted securities, are valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees. 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) Joint trading account Pursuant to an exemptive order from the Securities and Exchange Commission, the fund may transfer uninvested cash balances, including cash collateral received under security lending arrangements, into a joint trading account along with the cash of other registered investment companies and certain other accounts managed by Putnam Investment Management, LLC (“Putnam Management”), the fund’s manager, an indirect wholly-owned subsidiary of Putnam, LLC. These balances may be invested in issues of high-grade short-term investments having maturities of up to 397 days for collateral received under security lending arrangements and up to 90 days for other cash investments.

C) Repurchase agreements The fund, or any joint trading account, through its custodian, receives delivery of the underlying securities, the market value of which at the time of purchase is required to be in an amount at least equal to the resale price, including accrued interest. Collateral for certain tri-party repurchase agreements is held at the counterparty’s custodian in a segregated account for the benefit of the fund and the coun-terparty. 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). Gains or losses on securities sold are determined on the identified cost basis.

Interest income is recorded on the accrual basis. Dividend income, net of applicable withholding taxes, is recognized on the ex-dividend date except that certain dividends from foreign securities, if any, are recognized as soon as the fund is informed of the ex-dividend date. Non-cash dividends, if any, are recorded at the fair market value of the securities received. Dividends representing a return of capital or capital gains, if any, are reflected as a reduction of cost and/or as a realized gain when the amounts are conclusively determined.

E) Foreign currency translation The accounting records of the fund are maintained in U.S. dollars. The market value of foreign securities, currency holdings, and other assets and liabilities are recorded in the books and records of the fund after translation to U.S. dollars based on the exchange rates on that day. The cost of each security is determined using historical exchange rates. Income and withholding taxes are translated at prevailing exchange rates when earned or incurred. The fund does not isolate that portion of realized or unrealized gains or losses resulting from changes in the foreign exchange rate on investments from fluctua-tions arising from changes in the market prices of the securities. Such gains and losses are included with the net realized and unrealized gain or loss on investments. Net realized gains and losses on foreign currency transactions represent net realized

exchange gains or losses on closed forward currency contracts, disposition of foreign currencies, currency gains and losses realized between the trade and settlement dates on securities transactions and the difference between the amount of investment income and foreign withholding taxes recorded on the fund’s books and the U.S. dollar equivalent amounts actually received or paid. Net unrealized appreciation and depreciation of assets and liabilities in foreign currencies arise from changes in the value of open forward currency contracts and assets and liabilities other than investments at the period end, resulting from changes in the exchange rate. Investments in foreign securities involve certain risks, including those related to economic instability, unfavorable political developments, and currency fluctuations, not present with domestic investments.

F) 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.

G) Total return swap contracts The fund may enter into total return swap contracts, which are arrangements to exchange a market linked return for a periodic payment, both based on a notional principal amount. To the extent that the total return of the security, index or other financial measure underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the fund will receive a payment from or make a payment to the counterparty. Total return swap contracts are marked to market daily based upon quotations from market makers and the change, if any, is recorded as unrealized gain or loss. Payments received or made are recorded as realized gains or loss. Certain total return swap contracts may include extended effective dates. Income related to these swap contracts is accrued based on the terms of the contract. The fund could be exposed to credit or market risk due to unfavorable changes in the fluctuation of interest rates or in the price of the underlying security or index, the possibility that there is no liquid market for these agreements or that the counterparty may default on its obligation to perform. Risk of loss may exceed amounts recognized on the statement of assets and liabilities. Total return swap contracts outstanding at period end, if any, are listed after the fund’s portfolio.

H) Security lending The fund may lend securities, through its agents, to qualified borrowers in order to earn additional income. The loans are collateralized by cash and/or securities in an amount at least equal to the market value of the securities loaned. The market value of securities loaned is determined daily and any additional required collateral is allocated to the fund on the next business day. The risk of borrower default will be borne by the fund’s agents; the fund will bear the risk of loss with respect to the investment of the cash collateral. Income from securities lending is included in investment income on the statement of operations. At July 31, 2006, the value of securities loaned amounted to $326,835,678. The fund received cash collateral of $337,934,165 which is pooled with collateral of other Putnam funds into 24 issues of high grade short-term investments.

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

At July 31, 2006, the fund had a capital loss carryover of $3,052,570,108 available to the extent allowed by the Code to offset future net capital gain, if any. This capital loss carryover will expire on July 31, 2011.

J) Distributions to shareholders Distributions to shareholders from net investment income are recorded by the fund on the ex-dividend date. Distributions from capital gains, if any, are recorded on the ex-dividend date and paid at least annually. The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. These differences include temporary and permanent differences of losses on wash sale transactions, net operating loss and income on swap contracts. 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 July 31, 2006, the fund reclassified $40,400,876 to decrease distributions in excess of net investment income and $37,653,170 to decrease paid-in-capital, with a increase to accumulated net realized loss of $2,747,706.

The tax basis components of distributable earnings and the federal tax cost as of period end July 31, 2006 were as follows:

Unrealized appreciation	$ 619,515,328
Unrealized depreciation	(739,991,448)
	———————————————
Net unrealized depreciation	(120,476,120)
Capital loss carryforward	(3,052,570,108)
Cost for federal income
tax purposes	$ 8,798,318,820

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: 0.70% of the first $500 million of average net assets, 0.60% of the next $500 million, 0.55% of the next $500 million, 0.50% of the next $5 billion, 0.475% of the next $5 billion, 0.455% of the next $5 billion, 0.44% of the next $5 billion, 0.43% of the next $5 billion, 0.42% of the next $5 billion, 0.41% of the next $5 billion, 0.40% of the next $5 billion, 0.39% of the next $5 billion, 0.38% of the next $8.5 billion and 0.37% thereafter.

Putnam Management has agreed to waive fees and reimburse expenses of the fund through July 31, 2007 to the extent necessary to ensure that the fund’s expenses do not exceed the simple average of the expenses of all front-end load funds viewed by Lipper Inc. as having the same investment classification or objective as the fund.

The expense reimbursement is based on a comparison of the fund’s expenses with the average annualized operating expenses of the funds in its Lipper peer group for each calendar quarter during the fund’s last fiscal year, excluding 12b-1 fees and without giving effect to any expense offset and brokerage service arrangements that may reduce fund expenses. For the year ended July 31, 2006, Putnam Management did not waive any of its management fee from the fund.

During the year ended July 31, 2006, Putnam Management voluntarily reimbursed the fund $21,403 for net realized losses incurred from trading errors by the fund. The effect of the losses incurred and the reimbursal by Putnam Management of such losses had no impact on total return.

For the year ended July 31, 2006, Putnam Management has assumed $148,087 of legal, shareholder servicing and communication, audit and Trustee fees incurred by the fund in connection with certain legal and regulatory matters (including those described in Note 6).

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

Custodial functions for the fund’s assets are provided by Putnam Fiduciary Trust Company (“PFTC”), a subsidiary of Putnam, LLC. PFTC receives fees for custody services based on the fund’s asset level, the number of its security holdings and transaction volumes. Putnam Investor Services, a division of PFTC, provides investor servicing agent functions to the fund. Putnam Investor Services receives fees for investor servicing 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 July 31, 2006, the fund incurred $30,983,547 for these services.

The fund has entered into an arrangement with PFTC whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the fund’s expenses. The fund also reduced expenses through brokerage service arrangements. For the year ended July 31, 2006, the fund’s expenses were reduced by $3,295,475 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of which $1,998, 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 is not an independent Trustee, 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. Pension expense for the fund is included in Trustee compensation and expenses in the statement of operations. Accrued pension liability is included in Payable for Trustee compensation and expenses in the statement of assets and liabilities. The Trustees have terminated the Pension Plan with respect to any Trustee first elected after 2003.

The fund has adopted distribution plans (the “Plans”) with respect to its class A, class B, class C, class M and class R shares pursuant to Rule 12b-1 under the

Investment Company Act of 1940. The purpose of the Plans is to compensate Putnam Retail Management, a wholly-owned subsidiary of Putnam, LLC and Putnam Retail Management GP, Inc., for services provided and expenses incurred in distributing shares of the fund. The Plans provide for payments by the fund to Putnam Retail Management at an annual rate of up to 0.35%, 1.00%, 1.00%, 1.00% and 1.00% of the average net assets attributable to class A, class B, class C, class M and class R shares, respectively. The Trustees have approved payment by the fund at an annual rate of 0.25%, 1.00%, 1.00%, 0.75% and 0.50% of the average net assets attributable to class A, class B, class C, class M and class R shares, respectively.

For the year ended July 31, 2006, Putnam Retail Management, acting as underwriter, received net commissions of $229,156 and $2,828 from the sale of class A and class M shares, respectively, and received $1,989,749 and $6,053 in contingent deferred sales charges from redemptions of class B and class C shares, respectively. A deferred sales charge of up to 1.00% and 0.65% is assessed on certain redemptions of class A and class M shares, respectively. For the year ended July 31, 2006, Putnam Retail Management, acting as underwriter, received $2,704 and no monies on class A and class M redemptions, respectively.

Note 3: Purchases and sales of securities

During the year ended July 31, 2006, cost of purchases and proceeds from sales of investment securities other than short-term investments aggregated $7,589,850,266 and $10,256,010,629, respectively. There were no purchases or sales of U.S. government securities.

Note 5: Investment in Putnam Prime Money Market Fund

Pursuant to an exemptive order from the Securities and Exchange Commission, the fund invests in Putnam Prime Money Market Fund, an open-end management investment company managed by Putnam Management. Management fees paid by the fund are reduced by an amount equal to the management and administrative services fees paid by Putnam Prime Money Market Fund with respect to assets invested by the fund in Putnam Prime Money Market Fund. For the year ended July 31, 2006, management fees paid were reduced by $45,723 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 $1,462,501 for the year ended July 31, 2006. During the year ended July 31, 2006, cost of purchases and cost of sales of investments in Putnam Prime Money Market Fund aggregated $1,485,167,672 and $1,525,998,658, respectively.

Note 6: Regulatory matters and litigation

Putnam Management has entered into agreements with the Securities and Exchange Commission and the Massachusetts Securities Division settling charges connected with excessive short-term trading by Putnam employees and, in the case of the charges brought by the Massachusetts Securities Division, by participants in some Putnam-administered 401(k) plans. Pursuant to these settlement agreements, Putnam Management will pay a total of $193.5 million in penalties and restitution, with $153.5 million being paid to certain open-end funds and their shareholders. The amount will be allocated to shareholders and funds pursuant to a plan developed by an independent consultant, and will be paid following approval of the plan by the SEC and the Massachusetts Securities Division.

The Securities and Exchange Commission’s and Massachusetts Securities Division’s allegations and related matters also serve as the general basis for numerous lawsuits, including purported class action lawsuits filed against Putnam Management and certain related parties, including certain Putnam funds. Putnam Management will bear any costs incurred by Putnam funds in connection with these lawsuits. Putnam Management believes that the likelihood that the pending private lawsuits and purported class action lawsuits will have a material adverse financial impact on the fund is remote, and the pending actions are not likely to materially affect its ability to provide investment management services to its clients, including the Putnam funds.

Pursuant to a settlement with the Securities and Exchange Commission relating to Putnam Management’s brokerage allocation practices, on October 13, 2005 the fund received $9,590,469 in proceeds paid by Putnam Management. The fund had accrued a receivable for this amount in the prior fiscal year.

During the period, the fund received $6,125,083 from Putnam to address issues relating to the calculation of certain amounts paid by the Putnam mutual funds to Putnam for transfer agent services. This amount is included in Fees waived and reimbursed by Manager or affiliate on the Statement of operations. Review of this matter is ongoing and the amount received by the fund may be adjusted in the future. Such adjustment is not expected to be material.

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, 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.

Federal tax information
(Unaudited)

The Form 1099 you receive in January 2007 will show the tax status of all distributions paid to your account in calendar 2006.

Brokerage commissions
(Unaudited)

Brokerage commissions are paid to firms that execute trades on behalf of your fund. When choosing these firms, Putnam is required by law to seek the best execution of the trades, taking all relevant factors into consideration, including expected quality of execution and commission rate. Listed below are the largest relationships based upon brokerage commissions for your fund and the other funds in Putnam’s Large-Cap Growth group for the year ended July 31, 2006. The other Putnam mutual funds in this group are Putnam Growth Opportunities Fund, Putnam VT Growth Opportunities Fund, and Putnam VT Voyager Fund.

The top five firms that received brokerage commissions for trades executed for the Large-Cap Growth group are (in descending order) Goldman Sachs, Citigroup Global Markets, Merrill Lynch, UBS Warburg, and Deutsche Bank Securities. Commissions paid to these firms together represented approximately 43% of the total brokerage commissions paid for the year ended July 31, 2006.

Commissions paid to the next 10 firms together represented approximately 39% of the total brokerage commissions paid during the period. These firms are (in alphabetical order) Bank of America, Bear Stearns & Company, Credit Suisse First Boston, JP Morgan Clearing, Lehman Brothers, Morgan Stanley Dean Witter, RBC Capital Markets, Sanford Bernstein, SG Cowen Securities, and Wachovia Securities.

Additional information about brokerage commissions is available on the Securities and Exchange Commission (SEC) Web site at www.sec.gov. Putnam funds disclose commissions by firm to the SEC in semiannual filings on Form N-SAR.

Putnam puts your
interests first

In January 2004, Putnam began introducing a number of voluntary initiatives designed to reduce fund expenses, provide investors with more useful information, and help safeguard the interests of all Putnam investors. Visit www.putnam.com for details.

Cost-cutting initiatives

Reduced sales charges The maximum sales charge for class A shares has been reduced to 5.25% for equity funds (formerly 5.75%) and 3.75% for most income funds (formerly 4.50%) . The maximum sales charge for class M shares has been reduced to 3.25% for equity funds (formerly 3.50%) .*

Lower class B purchase limit To help ensure that investors are in the most cost-effective share class, the maximum amount that can be invested in class B shares has been reduced to $100,000. (Larger trades or accumulated amounts will be refused.)

Ongoing expenses will be limited Through calendar 2006, total ongoing expenses, including management fees for all funds, will be maintained at or below the average of each fund’s industry peers in its Lipper load-fund universe. For more information, please see the Statement of Additional information.

Improved disclosure

Putnam fund prospectuses and shareholder reports have been revised to disclose additional information that will help shareholders compare funds and weigh their costs and risks along with their potential benefits. Shareholders will find easy-to-understand information about fund expense ratios, portfolio manager compensation, risk comparisons, turnover comparisons, brokerage commissions, and employee and trustee ownership of Putnam funds. Disclosure of breakpoint discounts has also been enhanced to alert investors to potential cost savings.

Protecting investors’ interests

Short-term trading fee introduced To discourage short-term trading, which can interfere with a fund’s long-term strategy, a 2% short-term trading fee may be imposed on any Putnam fund shares (other than money market funds) redeemed or exchanged within five calendar days of purchase.

* The maximum sales charge for class A shares of Putnam Limited Duration Government Income Fund (formerly Putnam Intermediate U.S. Government Income Fund) and Putnam Floating Rate Income Fund remains 3.25% .

family of funds

Switch funds easily* You can move money from one Putnam fund to another within the same class of shares without a service charge.

Access your money easily You can have checks sent regularly or redeem shares any business day at the then-current net asset value, which may be more or less than the original cost of the shares. Class B and class C shares carry a sales charge that is applied to certain withdrawals.

How to buy additional shares You may buy shares through your financial advisor or directly from Putnam. To open an account by mail, send a check made payable to the name of the fund along with a completed fund application.

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.

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 all members of the Funds' Audit and Compliance Committee meet the financial literacy requirements of the New York Stock Exchange's rules and that Mr. Patterson, Mr. Stephens and Mr. Hill qualify as "audit committee financial experts" (as such term has been defined by the Regulations) based on their review of their 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
year	Audit	Audit-Related	Tax	All Other
ended	Fees	Fees	Fees	Fees

July 31, 2006	$182,314*	$ 2,566	$5,167	$ -
July 31, 2005	$172,566*	$--	$4,029	$7,534

* Includes fees of $8,903 and $7,460 billed by the fund’s independent auditor to the fund for audit procedures necessitated by regulatory and litigation matters for the fiscal years ended July 31, 2006 and July 31, 2005, respectively. These fees were reimbursed to the fund by Putnam Investment Management, LLC (“Putnam Management”).

For the fiscal years ended July 31, 2006 and July 31, 2005, the fund’s independent auditor billed aggregate non-audit fees in the amounts of $277,404 and $206,892 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.

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.

Fiscal	Audit-		All	Total
