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

From our present vantage point, it has become apparent that certain sectors of the U.S. economy have slowed somewhat, although the global economy continues to demonstrate healthy growth. In recent weeks, financial markets have reflected increased uncertainty about the effects of the housing market decline and tighter credit standards by mortgage lenders on the U.S. economy. However, we believe that the U.S. economy is flexible enough to adapt to these challenges, just as it has adapted to other challenges that have arisen in the course of the recent economic expansion.

As you may have heard, on February 1, 2007, Marsh & McLennan Companies, Inc. announced that it had signed a definitive agreement to sell its ownership interest in Putnam Investments Trust, the parent company of Putnam Management and its affiliates, to Great-West Lifeco Inc. Great-West Lifeco Inc. 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. This transaction is subject to regulatory approvals and other conditions, including the approval of new management contracts by shareholders of a substantial number of Putnam funds at shareholder meetings scheduled for May 15, 2007. Proxy solicitation materials related to these meetings, which provide detailed information regarding the proposed transaction, were recently mailed. We currently expect the transaction to be completed by the middle of 2007.

Putnam’s team of investment and business professionals will continue to be led by Putnam President and Chief Executive Officer Ed Haldeman. Your Trustees have been actively involved through every step of the discussions, and we will continue in our role of overseeing the Putnam funds on your behalf.

We would like to take this opportunity to announce that a new independent Trustee, Kenneth R. Leibler, has joined your fund’s Board of Trustees. Mr. Leibler has had a distinguished career as a leader in the investment management industry. He is a founding partner of and advisor to the Boston Options Exchange; a Trustee of Beth Israel Deaconess Hospital in Boston; a lead director of Ruder Finn Group, a global communications and advertising firm; and a director of Northeast Utilities.

In the following pages, members of your fund’s management team discuss the fund’s performance and strategies for the fiscal period ended February 28, 2007, and provide their outlook for the months ahead. As always, we thank you for your support of the Putnam funds.

Putnam High Yield Trust: a disciplined approach
to seeking high current income and capital growth

Unlike most types of fixed-income investments, high-yield bonds are more influenced by the performance of issuing companies than by interest rates. For this reason, distinguishing between opportunities and pitfalls in the high-yield bond market requires a rigorous selection process. With Putnam High Yield Trust, this process is highlighted by exhaustive research, investment diversification, and timely portfolio adjustments.

Because of the risks of high-yield bond investing, in-depth credit research is essential. The fund’s research team — more than 20 professionals, including analysts who specialize by industry — visits with the management of issuing companies and analyzes each company’s profitability and capital structure. The team then considers this information in the context of the bond’s total return profile before deciding whether it is an appropriate investment for the fund.

The fund’s portfolio typically consists of a broad range of industries and companies. Holdings are diversified across industry sectors and among bonds with different credit ratings. While the fund invests primarily in the bonds of U.S. companies, its diversified approach allows it to include foreign bonds as well. Among these securities, investments in emerging-market bonds can enhance the fund’s appreciation potential. The fund also invests in convertible securities as well as bank loans. Although diversification does not ensure a profit or protect against a loss and it is possible to lose money in a diversified portfolio, the fund’s diversification can help reduce the volatility that typically comes with higher-risk investments.

As the bond markets shift over time, the fund’s management team looks for ways to capitalize on developments that affect fixed-income securities in general and high-yield bonds in particular. For example, when interest rates are low, the fund may pursue the higher income potential offered by lower-quality issues. On the other hand, when interest rates are on the rise, yield spreads —that is, the difference in yield between higher-and lower-rated bonds of comparable maturities — typically narrow. In response, the fund may shift its emphasis to higher-quality high-yield bonds.

Lower-rated bonds may offer higher yields in return for more risk. Mutual funds that invest in bonds are subject to certain risks, including interest-rate risk, credit risk, and inflation risk. As interest rates rise, the prices of bonds fall. Long-term bonds are more exposed to interest-rate risk than short-term bonds. Unlike bonds, bond funds have ongoing fees and expenses.

What makes a bond
“high yield”?

High-yield bonds are fixed-income investments typically issued by companies that lack an established earnings track record or a solid credit history. In general, high-yield bonds offer higher interest rates than investment-grade bonds to compensate for their increased risk. Because of this added risk, these bonds are rated below investment grade by an independent rating agency (for example, the lowest Moody’s Investors Service rating of investment-grade bonds is Baa). The lower the rating, the greater the possibility that a bond’s issuer will be unable to make interest payments or repay the principal.

BOND RATINGS

Moody’s	Grade

Aaa	Investment

Aa	Investment

Baa	Investment

Ba, B	High yield

Caa/Ca	High yield

C	High yield

High-yield bonds have offered greater return
potential than investment-grade bonds.

Putnam High Yield Trust seeks high current income through a portfolio of higher-yielding, lower-rated corporate bonds diversified across different industry sectors. It has a secondary objective of capital growth when consistent with high current income. This fund may be suitable for investors who can accept a higher level of risk in exchange for a potentially higher level of income than that available from higher-quality bonds.

Report from the fund managers

The period in review

Against a backdrop of continued solid economic growth, low default rates, and global demand for higher-yielding investments, high-yield bonds extended their long-standing rally during the six-month period. Your fund’s performance at net asset value (NAV, or without sales charges) outpaced the average for its Lipper peer group, but finished slightly behind the return of its benchmark index. We attribute the underperformance relative to the benchmark to the fund’s smaller-than-benchmark position in the lowest tiers of the corporate debt market, particularly with regard to distressed bonds, which were among the strongest performers for the period. The fund’s relative strength in comparison to its peer group most likely reflects our security selections and weightings in the energy and diversified media sectors, which outperformed the broader market. Amid an equity market rally, fund performance was also bolstered by superior performance from select convertible bond holdings, as well as other equity-sensitive positions.

Market overview

Sustained solid economic growth, a stream of positive earnings news, historically low default rates, and signs that inflation was in check all contributed to the rally in the high-yield bond market over the past six months. All higher-risk assets benefited from the Federal Reserve’s (the Fed’s) decision to suspend its credit-tightening program in August 2006. Furthermore, the Fed remained on the sidelines throughout the period, holding the federal funds rate steady at 5.25%, which helped sustain the rally.

Prior to the Fed’s policy change, both equity and high-yield bond markets had suffered from the impact of rising interest rates and concern about the potential for income-eroding inflation that rate increases represent. Once investors realized that the hoped-for “soft landing” the Fed was trying to engineer might be within reach, market sentiment turned positive and equity and high-yield bonds rallied. A soft landing occurs when economic growth slows to less than inflationary levels but is still strong

enough to sustain job creation and corporate profits. This rally lasted until the final days of the period when an equity market sell-off in China set off a risk-averse reaction across all higher-risk asset classes, including high-yield bonds. Despite this negative surprise at period-end, the high-yield bond market recorded strong positive results overall.

In addition to constructive fundamentals, the high-yield bond market benefited from strong technical factors. Demand for yield remained robust on a global basis, as yield-hungry investors demonstrated an increased willingness to take on risk amid growing confidence in a soft landing and declining market volatility. The market also easily absorbed new issuance.

The average yield spread, or difference in yield between bonds of comparable maturity, began the period near historic lows. When this occurs, it means that investors are paying more for the additional risks represented by high-yield bonds, but are not receiving the greater reward potential one would expect to accompany such risks. Constructive fundamental and technical factors led to the continued narrowing of the spread between rates on high-yield bonds and Treasuries.

Strategy overview

Your fund invests across most sectors of the high-yield bond market and employs multiple strategies in pursuit of its objectives. We believe that having

diversified return sources across a range of sectors and opportunity types contributes to more consistent results over time and enables us to manage risk more effectively. Generally, our investment decisions involve the following considerations: valuation, portfolio construction, and risk management.

In-depth credit research is the primary means by which we assess a particular issue’s value relative to its longer-term potential, as well as in comparison to other opportunities we are considering. We evaluate bond issuers based on their competitive advantages (which we expect to be sustainable), the viability of their capital structure (i.e., their financial framework, including such factors as long-term debt and net worth), their capacity to generate sufficient cash flow to cover debt, and the level of downside protection provided to investors. We focus our efforts on avoiding price erosion on bonds purchased or trading at par (face value), and we use our industry/valuation expertise to pursue opportunities among stressed bonds.

Risk management is a focal point within our portfolio construction process. Our proprietary risk management tools let us break down and evaluate risk in terms of macroeconomic, sector, subsector, and individual security factors. With this combination of research and risk management, we believe we are able to evaluate opportunities and build portfolios that offer shareholders an

optimal balance between risk exposure and potential reward.

During the semiannual period, we emphasized bonds from the middle credit tiers of the high-yield market, which generally meant B-rated securities. In our opinion, the risk/reward profile of lower-rated bonds has become much less attractive, and we trimmed the fund’s exposure to them in order to reduce the portfolio’s credit risk. (Credit risk is the risk that a bond issuer could default and fail to pay interest and repay principal in a timely manner.) While we expect this strategy to prove rewarding over the long term, it detracted from relative results versus the fund’s benchmark during the period, as the lowest-rated credits strengthened.

Your fund’s holdings

Fund performance continued to benefit from an overweight position in the energy sector, where fundamentals remained strong and reflected relatively high demand on a global basis. Securities issued by portfolio holding XCL, an oil and natural gas exploration and production company, were among the top contributors to fund performance, as their prices rose significantly on news of bids for the company. Positive fundamentals drove up the value of bonds issued by natural gas companies El Paso and Williams. El Paso is one of North America’s largest independent natural gas producers. Williams is also in the business of natural gas exploration, production, processing, and transportation.

Chaparral Steel Co. (0.6%)	10%, 2013	Basic materials

Demand for natural gas — from both electrical power generators and individual consumers — continues to grow.

Holdings of bonds issued by companies in the automotive sector also bolstered relative results. In particular, bonds issued by Ford Motor Credit and General Motors Acceptance (GMAC) advanced robustly. Strength in this sector was, in part, the result of investors realizing that the market had overreacted to the challenges faced by automakers. In addition, investors responded favorably to announcements of cost cuts and liquidity enhancements. Finally, bonds issued by GMAC benefited from the completion of the sale of that entity by General Motors to an investment consortium led by Cerberus FIM Investors. Investors expect GMAC to benefit from access to lower-cost funds as it assumes an independent credit profile from General Motors.

Bonds issued by Charter Communications, a broadband communications company, contributed to results, as the company benefited from investors’ preference for higher-yielding, lower-quality issues during the period. Charter Communications provides a full range of advanced residential broadband services and business-to-business video, data, and Internet protocol solutions.

Select holdings in the media and publishing sectors also delivered solid results for the period. Holdings of Interpublic Group, a global marketing communications and marketing services company, and of PRIMEDIA, a leading publisher of targeted media, advanced amid continued improvements in company fundamentals. The performance of high-yield bonds issued by certain theatre operators — a subsector within the broader entertainment sector — also contributed to relative results.

As noted earlier, the fund’s limited exposure to distressed or defaulted bonds (bonds rated CCC and below) was the primary detractor from performance during the period. As noted earlier, many such bonds rallied amid strong demand for yield and investors’ greater tolerance for risk. The fund did not own or had underweight positions in a number of high-profile bonds that fell into the “defaulted” category, such as those issued by electric utility Calpine, airline giants Delta and Northwest, and automotive component maker Delphi. These bonds were among the stronger performers of the period, but the fund did not benefit from their strength. In addition, the fund did not own bonds issued by telecom provider Suncom, forest products maker Tembec, and heal th-care company Rotech Healthcare, which are all companies that we believe are in stressed situations. Our decision to avoid these bonds, which actually helped performance in earlier periods, proved detrimental to performance during the period, as they gained substantially in value.

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.

We begin the second half of the fund’s 2007 fiscal year with a somewhat constructive outlook for the high-yield market. It appears that high-yield issuers are continuing to demonstrate strong financial performance, and capital markets have been providing them with ample liquidity. Defaults remain at record lows as do forward indicators of potential default levels, and the most recent earnings performance for high-yield companies was generally positive. However, the longer this benign environment persists, the more aggressive the capital structures we have seen are likely to become. Already, headline-grabbing, highly leveraged buyouts are appearing more frequently.

Given the high-yield market’s multi-year advances, we believe that in the future, fund performance is likely to be driven more by yield and less by capital appreciation. We consequently plan to continue selectively reducing the fund’s exposure to the lowest credit tiers while bolstering its already larger-than-benchmark position in the middle-tier credits (those rated single B). In our opinion, favoring the higher-quality tiers within the universe of lower-rated bonds while diversifying investments across many different industries and sectors should enable the fund to continue to perform well.

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

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 maximum sales charge of 3.75% 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 for the first year and 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. For a portion of the period, this fund 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 advisor.

Review your fund’s expenses

The table below shows the expenses you would have paid on a $1,000 investment in Putnam High Yield Trust from September 1, 2006, to February 28, 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 Y

Expenses paid per $1,000*	$ 5.27	$ 9.12	$ 9.11	$ 6.55	$ 6.54	$ 3.98

Ending value (after expenses)	$1,081.90	$1,078.10	$1,076.90	$1,081.50	$1,078.50	$1,082.70

* 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 2/28/07. 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.

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 Y

Expenses paid per $1,000*	$ 5.11	$ 8.85	$ 8.85	$ 6.36	$ 6.36	$ 3.86

Ending value (after expenses)	$1,019.74	$1,016.02	$1,016.02	$1,018.50	$1,018.50	$1,020.98

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 Y
Your fund’s annualized
expense ratio	1.02%	1.77%	1.77%	1.27%	1.27%	0.77%

Average annualized expense
ratio for Lipper peer group*	1.12%	1.87%	1.87%	1.37%	1.37%	0.87%

* 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 12/31/06. 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.

Funds that invest in bonds or other fixed-income instruments may have higher turnover than funds that invest only in stocks. Short-term bond funds tend to have higher turnover than longer-term bond funds, because shorter-term bonds will mature or be sold more frequently than longer-term bonds. You can use the table below to compare your fund’s turnover with the average turnover for funds in its Lipper category.

Turnover comparisons

Percentage of holdings that change every year

	2006	2005	2004	2003	2002

Putnam High Yield Trust	46%	41%	62%	75%	74%*

Lipper High Current Yield Funds
category average	83%	73%	95%	98%	99%

Turnover data for the fund is calculated based on the fund’s fiscal-year period, which ends on August 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 12/31/06.

* Portfolio turnover excludes the impact of assets received from the acquisition of Putnam High Yield Trust II.

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 Morningstar Risk.

Your fund’s Morningstar^®Risk

Your fund’s Morningstar Risk is shown alongside that of the average fund in its Morningstar category. The risk bar broadens the comparison by translating the fund’s Morningstar Risk into a percentile, which is based on the fund’s ranking among all funds rated by Morningstar as of March 31, 2007. A higher Morningstar Risk generally indicates that a fund’s monthly returns have varied more widely.

Morningstar determines a fund’s Morningstar Risk by assessing variations in the fund’s monthly returns — with an emphasis on downside variations — over a 3-year period, if available. Those measures are weighted and averaged to produce the fund’s Morningstar Risk. The information shown is provided for the fund’s class A shares only; information for other classes may vary. 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 Morningstar Risk does not mean that you cannot lose money on an investment in a fund. Copyright 2007 Morningstar, Inc. All Rights Reserved.

Trustees	$ 560,000	$101,000,000

Putnam employees	$4,642,000	$459,000,000

Fund manager compensation

The total 2006 fund manager compensation that is attributable to your fund is approximately $1,300,000. This amount includes a portion of 2006 compensation paid by Putnam Management to the fund managers listed in this section for their portfolio management responsibilities, calculated based on the fund assets they manage taken as a percentage of the total assets they manage. The compensation amount also includes a portion of the 2006 compensation paid to the Group Chief Investment Officer of the fund’s broader investment category for his oversight responsibilities, calculated based on the fund assets he oversees taken as a percentage of the total assets he oversees. This amount does not include compensation of other personnel involved in research, trading, administration, systems, compliance, or fund operations; nor does it include non-compensation costs. These percentages are determined as of the fund’s fiscal period-end. For personnel who joined Putnam M anagement during or after 2006, the calculation reflects annualized 2006 compensation or an estimate of 2007 compensation, as applicable.

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 3.75% 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 and the sub-management contract between Putnam Management’s affiliate, Putnam Investments Limited (“PIL”), and 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 in dependent counsel and independent staff. The Contract Committee reviewed and discussed key aspects of this information with all of the Independent Trustees. Upon completion of this review, the Contract Committee recommended, and the Independent Trustees approved, the continuance of your fund’s management contract and sub-management contract, effective July 1, 2006. (Because PIL is an affiliate of Putnam Management and Putnam Management remains fully responsible for all services provided by PIL, the Trustees have not evaluated PIL as a separate entity, and all subsequent references to Putnam Management below include reference to PIL as necessary or appropriate in the context.)

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

These conclusions were based on a comprehensive consideration of all information provided to the Trustees and were not the result of any single factor. Some of the factors that figured particularly in the Trustees’ deliberations and how the Trustees considered these factors are described below, although individual Trustees may have evaluated the information presented differently, giving different weights to various factors. It is also important to recognize that the fee arrangements for your fund and the other Putnam funds are the result of many years of review and discussion between the Independent Trustees and Putnam Management, that certain aspects of such arrangements may receive greater scrutiny in some years than others, and that the Trustees’ conclusions may be based, in part, on their consideration of these same arrangements in prior years.

Management fee schedules and categories; total expenses

The Trustees reviewed the management 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 48th percentile in management fees and in the 31st 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). (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, 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 C ommittee’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 fu nds in the aggregate and as to individual funds. The Trustees reviewed Putnam Management’s cost allocation methodology with the assistance of independent consultants and concluded that this methodology was reasonable and well-considered.

Investment performance

The quality of the investment process provided by Putnam Management represented a major factor in the Trustees’ evaluation of the quality of services provided by Putnam Management under your fund’s management contract. The Trustees were assisted in their review of the Putnam funds’ investment process and performance by the work of the Investment Process Committee of the Trustees and the Investment Oversight Committees of the Trustees, which meet on a regular monthly basis with the funds’ portfolio teams throughout the year. The Trustees concluded that Putnam Management generally provides a high-quality investment process — as measured by the experience and skills of the individuals assigned to the management of fund portfolios, the resources made available to such personnel, and in general the ability of Putnam Management to attract and retain high-quality personnel — but also recognize that this does not guarantee favorable investment results for every fund in every time period. The Trustees considered the investment performance of each fund over multiple time periods

and considered information comparing each fund’s performance with various benchmarks and with the performance of competitive funds.

The Trustees noted the satisfactory investment performance of many Putnam funds. They also noted the disappointing investment performance of certain funds in recent years and discussed with senior management of Putnam Management the factors contributing to such underperformance and actions being taken to improve performance. The Trustees recognized that, in recent years, Putnam Management has made significant changes in its investment personnel and processes and in the fund product line to address areas of underperformance. In particular, they noted the important contributions of Putnam Management’s leadership in attracting, retaining and supporting high-quality investment professionals and in systematically implementing an investment process that seeks to merge the best features of fundamental and quantitative analysis. The Trustees indicated their intention to continue to monitor performance trends to assess the effectiveness of these changes and to evaluate whether additional changes to address areas of underperformance are warranted.

In the case of your fund, the Trustees considered that your fund’s class A share cumulative total return performance at net asset value was in the following percentiles of its Lipper Inc. peer group (Lipper High Current Yield 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

22nd	24th	28th

(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 435, 382, and 310 funds, respectively, in your fund’s Lipper peer group.* Past performance is no guarantee of future performance.)

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

* The percentile rankings for your fund’s class A share annualized total return performance in the Lipper High Current Yield Funds category for the one-, five- and ten-year periods ended March 31, 2007, were 34%, 28%, and 51% respectively. Over the one-, five- and ten-year periods ended March 31, 2007, the fund ranked 149th out of 445, 86th out of 315, and 64th out of 126 funds, respectively. Note that this more recent information was not available when the Trustees approved the continuance of your fund’s management contract.

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 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 cli ents, as well as the differences between the services that Putnam Management provides to the Putnam funds and those that it provides to institutional clients of the firm, but did not rely on such comparisons to any significant extent in concluding that the management fees paid by your fund are reasonable.

Approval of new management and sub-management contracts
in connection with pending change in control

As discussed in the “Message from the Trustees” at the beginning of this shareholder report, on February 1, 2007, Marsh & McLennan Companies, Inc. announced that it had signed a definitive agreement to sell its ownership interest in Putnam Investments Trust, the parent company of Putnam Management and its affiliates, to Great-West Lifeco Inc., a member of the Power Financial Corporation group of companies. This transaction is subject to regulatory approvals and other conditions, including the approval of new management contracts by shareholders of a substantial number of Putnam funds at shareholder meetings scheduled for May 15, 2007. Proxy solicitation materials related to these meetings, which provide detailed information regarding the transaction, were recently mailed. The transaction is currently expected to be completed by the middle of 2007.

At an in-person meeting on February 8-9, 2007, the Trustees considered the approval of new management contracts for each Putnam fund (and, in the case of your fund, a new sub-management contract) proposed to become effective upon the closing of the transaction, and the filing of a preliminary proxy statement. At an in-person meeting on March 8-9, 2007, the Trustees considered the approval of the final forms of the proposed new management contracts for each Putnam fund (and, in the case of your fund, the new sub-management contract) and the proxy statement. They reviewed the terms of the proposed new management contracts and the differences between the proposed new management contracts and the current management contracts. They noted that the terms of the proposed new management contracts were substantially identical to the current management contracts, except for certain changes developed at the initiative of the Trustees and designed largely to address inconsistenc ies among various of the existing contracts, which had been developed and implemented at different times in the past. They noted, in the case of your fund, that the terms of the proposed new sub-management contract were identical to the current sub-management contract, except for the effective date. In considering the approval of the proposed new management contracts (and, in the case of your fund, the new sub-management contract), the Trustees also considered, as discussed further in the proxy statement, various matters relating to the transaction. Finally, in considering the proposed new management contracts (and, in the case of your fund, the new sub-management contract), the Trustees also took into account their deliberations and conclusions (discussed above in the preceding paragraphs of the “Trustee Approval of Management Contract” section) in connection with the most recent annual approval of the continuance of the Putnam funds’ management (and, in the case of your fund, sub-management) contracts effective July 1, 2006, and the extensive materials that they had reviewed in connection with that approval process. Based upon the foregoing considerations, on March 9, 2007, the Trustees, including all of the Independent Trustees, unanimously approved the proposed new management contracts (and, in the case of your fund, the new sub-management contract) and determined to recommend their approval to the shareholders of the Putnam funds.

Shareholders may obtain the fund’s Forms N-Q on the SEC’s Web site at www.sec.gov. In addition, the fund’s Forms N-Q may be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC’s Web site or the operation of the Public Reference Room.

Financial statements

A guide to financial statements

These sections of the report, as well as the accompanying Notes, 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 period.

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. Dividend sources are estimated at the time of declaration. Actual results may vary. Any non-taxable return of capital cannot be determined until final tax calculations are completed after the end of the fund’s fiscal year.

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.

Notes to financial statements 2/28/07 (Unaudited)

Note 1: Significant accounting policies

Putnam High Yield Trust (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 high current income by investing primarily in high-yielding, lower-rated fixed-income securities. These securities may have a higher rate of default. Capital growth is a secondary goal when consistent with achieving high current income.

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 3.75% 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 sa me 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 certain college savings plans.

Effective October 2, 2006, a 1.00% redemption fee may apply on any shares purchased on or after such date that are redeemed (either by selling or exchanging into another fund) within 90 days of purchase. The redemption fee is accounted for as an addition to paid-in-capital. Prior to October 2, 2006, a 2.00% redemption fee applied to any shares that were redeemed (either by selling or exchanging into another fund) within 5 days of purchase.

A 1.00% redemption fee applied to any shares that were redeemed (either by selling or exchanging into another fund) within 6–90 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. Market quotations are not considered to be readily available for certain debt obligations; such investments are valued on the basis of valuations furnished by an independent pricing service approved by the Trustees or dealers selected by Putnam Investment Management, LLC (“Putnam Management”), the fund’s manager, an indirect wholly-owned subsidiary of Putnam, LLC. Such services or dealers determine valuations for normal institutional-size trading units of such securities using methods based on market transactions for comparable securities and various relationships, generally recognized by institutional traders, between securities. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange and ther efore 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. Certain investments, including certain restricted securities, are also valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees. The fair value of securities is generally determined as the amount that the fund could reasonably expect to realize from an orderly disposition of such securi ties 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 “SEC”), 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 Management. 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. All premiums/discounts are amortized/accreted on a yield-to-maturity basis.

Securities purchased or sold on a forward commitment or delayed delivery basis may be settled a month or more after the trade date; interest income is accrued based on the terms of the securities. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract. The fund earned certain fees in connection with its senior loan purchasing activities. These fees are treated as market discount and are recorded as income in the statement of operations.

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 fluctuations 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) Forward currency contracts The fund may buy and sell forward currency contracts, which are agreements between two parties to buy and sell currencies at a set price on a future date. These contracts are used to protect against a decline in value relative to the U.S. dollar of the currencies in which its portfolio securities are denominated or quoted (or an increase in the value of a currency in which securities a fund intends to buy are denominated, when a fund holds cash reserves and short term investments), or for other investment purposes. The U.S. dollar value of forward currency contracts is determined using current forward currency exchange rates supplied by a quotation service. The market value of the contract will fluctuate with changes in currency exchange rates. The contract is marked to market daily and the change in market value is recorded as an unrealized gain or loss. When the c ontract 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. The fund could be exposed to risk if the value of the currency changes unfavorably, if the counterparties to the contracts are unable to meet the terms of their contracts or if the fund is unable to enter into a closing position. Risks may exceed amounts recognized on the statement of assets and liabilities. Forward currency contracts outstanding at period end, if any, are listed after the fund’s portfolio.

G) Credit default contracts The fund may enter into credit default contracts where one party, the protection buyer, makes an upfront or periodic payment to a counter party, the protection seller, in exchange for the right to receive a contingent payment. The maximum amount of the payment may equal the notional amount, at par, of the underlying index or security as a result of a related credit event. An upfront payment received by the fund, as the protection seller, is recorded as a liability on the fund’s books. An upfront payment made by the fund, as the protection buyer, is

recorded as an asset on the fund’s books. Periodic payments received or paid by the fund are recorded as realized gains or losses. The credit default contracts are marked to market daily based upon quotations from an independent pricing service or market makers and the change, if any, is recorded as unrealized gain or loss. Payments received or made as a result of a credit event or termination of the contract are recognized, net of a proportional amount of the upfront payment, as realized gains or losses. In addition to bearing the risk that the credit event will occur, the fund could be exposed to market risk due to unfavorable changes in interest rates or in the price of the underlying security or index, the possibility that the fund may be unable to close out its position at the same time or at the same price as if it had purchased comparable publicly traded securities or that the counterparty may default on its obligation to perform. Risks of loss may excee d amounts recognized on the statement of assets and liabilities. Credit default contracts outstanding at period end, if any, are listed after the fund’s portfolio.

H) Securities 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 February 28, 2007, the value of securities loaned amounted to $37,586,728. The fund received cash collateral of $38,923,402 which is pooled with collateral of other Putnam funds into 28 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 August 31, 2006, the fund had a capital loss carryover of $1,727,813,678 available to the extent allowed by the Code to offset future net capital gain, if any. The amount of the carryover and the expiration dates are:

As a result of the October 27, 2006 merger of Putnam Managed High Yield Trust into the fund, the fund acquired $32,094,100 in capital loss carryovers which are subject to limitations imposed by the Code. The acquired capital loss carryovers and their expiration dates are:

$ 4,168,119	August 31, 2007

3,778,275	August 31, 2008

8,384,999	August 31, 2009

11,264,568	August 31, 2010

1,858,608	August 31, 2011

1,322,746	August 31, 2012

918,321	August 31, 2013

398,464	August 31, 2014

Pursuant to federal income tax regulations applicable to regulated investment companies, the fund has elected to defer to its fiscal year ending August 31, 2007 $23,250,705 of losses recognized during the period November 1, 2005 to August 31, 2006 a portion of which could be limited by Section 381 of the Code.

The aggregate identified cost on a tax basis is $2,344,753,357, resulting in gross unrealized appreciation and depreciation of $79,186,860 and $59,560,606, respectively, or net unrealized appreciation of $19,626,254.

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. Dividend sources are estimated at the time of declaration. Actual results may vary. Any non-taxable return of capital cannot be determined until final tax calculations are completed after the end of the fund’s fiscal year. 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.

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, and 0.43% thereafter.

Putnam Management has agreed to waive fees and reimburse expenses of the fund through August 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 period ended February 28, 2007, Putnam Management did not waive any of its management fee from the fund.

Putnam Investments Limited (“PIL”), an affiliate of Putnam Management, is authorized by the Trustees to manage a separate portion of the assets of the fund as determined by Putnam Management from time to time. Putnam Management pays a quarterly sub-management fee to PIL for its services at an annual rate of 0.40% of the average net assets of the portion of the fund managed by PIL.

Putnam Management voluntarily reimbursed the fund $148,544 for a trading error which occurred during the period. The effect the losses incurred and the reimbursement by Putnam Management of such losses had no impact on total return.

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

Custodial functions for the fund’s assets were provided by Putnam Fiduciary Trust Company (“PFTC”), a subsidiary of Putnam, LLC, and by State Street Bank and Trust Company. Custody fees are based on the fund’s asset level, the number of its security holdings and transaction volumes. Putnam Investor Services, a division of PFTC, provided investor servicing agent functions to the fund. Putnam Investor Services received 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 period ended February 28, 2007, the fund incurred $1,914,434 for custody and investor servicing agent functions provided by PFTC.

The fund has entered into arrangements with PFTC and State Street Bank and Trust Company whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the fund’s expenses. For the six months ended February 28, 2007, the fund’s expenses were reduced by $270,509 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of which $693, 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. 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 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%, 0.50% and 0.50% of the average net assets attributable to class A, class B, class C, class M and class R shares, respectively.

For the six months ended February 28, 2007, Putnam Retail Management, acting as underwriter, received net commissions of $53,539 and $662 from the sale of class A and class M shares, respectively,

and received $172,054 and $2,090 in contingent deferred sales charges from redemptions of class B and class C shares, respectively.

A deferred sales charge of up to 1.00% and 0.40% is assessed on certain redemptions of class A and class M shares, respectively. For the period ended February 28, 2007, Putnam Retail Management, acting as underwriter, received $987 and no monies on class A and class M redemptions, respectively.

Note 3: Purchases and sales of securities

During the six months ended February 28, 2007, cost of purchases and proceeds from sales of investment securities other than short-term investments aggregated $841,834,038 and $888,757,669, respectively. There were no purchases or sales of U.S. government securities.

Information presented in the Statement of operations and changes in net assets reflect only the operations of Putnam High Yield Trust.

Note 7: Senior loan commitments

Senior loans are purchased or sold on a when-issued or delayed delivery basis and may be settled a month or more after the trade date, which from time to time can delay the actual investment of available cash balances; interest income is accrued based on the terms of the securities. Senior loans can be acquired through an agent, by assignment from another holder of the loan, or as a participation interest in another holder’s portion of the loan. When the fund invests in a loan or participation, the fund is subject to the risk that an intermediate participant between the fund and the borrower will fail to meet its obligations to the fund, in addition to the risk that the borrower under the loan may default on its obligations.

Note 8: Unfunded loan commitments

As of February 28, 2007, the fund had unfunded loan commitments of $577,500, which could be extended at the option of the borrower, pursuant
to the following loan agreement with the following borrower:

Note 10: Regulatory matters and litigation

In late 2003 and 2004, Putnam Management settled charges brought by the Securities and Exchange Commission (the “SEC”) and the Massachusetts Securities Division (“MSD”) in connection with excessive short-term trading by certain former Putnam employees and, in the case of charges brought by the MSD, excessive short-term trading by participants in some Putnam-administered 401(k) plans. Putnam Management agreed to pay $193.5 million in penalties and restitution, of which $153.5 million will be distributed to certain open-end Putnam funds and their shareholders after the SEC and MSD approve a distribution plan being developed by an independent consultant. The allegations of the SEC and MSD and related matters have served as the general basis for certain lawsuits, including purported class action lawsuits filed against Putnam Management and, in a limited number of cases, against some Putnam funds. Putnam Management believes that these lawsuits will ha ve 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.

In connection with a settlement between Putnam and the fund’s Trustees in September 2006, the fund received $127,052 from Putnam to address issues relating to the calculation of certain amounts paid by the Putnam mutual funds to Putnam for transfer agent services.

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 11: 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 will become effective for fiscal years beginning after December 15, 2006 but will also apply to tax positions reflected in the fund’s financial statements as of that date. No determination has been made whether the adoption of the Interpretation will require the fund to make any adjustments to its net assets or have any other effect on the fund’s financial statements. The effects of implementing this pronouncement, if any, will be noted in the fund’s next semiannual financial statements.

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

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 2007, 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 1% short-term trading fee may be imposed on any Putnam fund shares (other than money market funds) redeemed or exchanged within seven calendar days of purchase (for certain funds, this fee applies for 90 days).

* The maximum sales charge for class A shares of Putnam Limited Duration Government Income Fund and Putnam Floating
Rate Income Fund remains 3.25% .

Services for shareholders

Investor services

Help your investment grow Set up a program for systematic investing from a Putnam fund or from your own savings or checking account. (Regular investing does not guarantee a profit or protect against loss in a declining market.)

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. To add to an existing account, complete the investment slip found at the top of your Confirmation of Activity statement and return it with a check payable to your fund.
