Putnam VT The George Putnam Fund of Boston


Putnam Investments is pleased to provide this annual report for shareholders of Putnam Variable Trust, a variable annuity offering you access to 28 funds and a wide range of investment choices. Putnam Variable Trust funds are the underlying investments for the variable insurance product subaccounts.

We are pleased to announce several important changes to our equity fund lineup and portfolio management under President and Chief Executive Officer Robert L. Reynolds. Key among them is replacing the team management structure of Putnam equity funds with a more nimble decision-making process that vests full authority and responsibility with individual fund managers. In other moves aimed at achieving performance excellence, Putnam has bolstered its ranks of seasoned equity analysts with several important hires.

INVESTMENT OBJECTIVE  
Balanced investment composed of a well-diversified portfolio of stocks
and bonds producing capital growth and current income

Data represents past performance. Past performance does not guarantee future results. More recent returns may be less or more than those shown. Investment return and principal value will fluctuate, and you may have a gain or a loss when you sell your shares. All total return figures are at net asset value and exclude contract charges and expenses, which are added to the variable annuity contracts to determine total return at unit value. Had these charges and expenses been reflected, performance would be lower. For more recent performance, contact your variable annuity provider who can provide you with performance that reflects the charges and expenses at your contract level.

MANAGEMENT TEAM’S REPORT AND OUTLOOK

The credit markets contracted sharply in 2008, creating widespread turmoil in the financial markets. As investors largely avoided risky investments, all asset classes struggled, except for the relative safety of U.S. Treasury bonds. Given the upheaval, investors experiencing increasing duress began to liquidate their Aaa-rated fixed-income holdings. This selling pressure caused bond prices to decline significantly and yield spreads to widen to greater-than-normal levels for Aaa-rated securities. This adversely affected the bond portion of the fund, which is primarily focused on this area of the fixed-income market. Stock investments, which comprise over 50% of the net assets of the fund, also proved disappointing amid the historic market correction. Consequently, the fund’s class IA shares had a loss of 40.57% at net asset value for the 12 months ended December 31, 2008.

Since early in the period, the co-managers found compelling opportunities in the distressed sectors of the mortgage-backed market, particularly among Aaa-rated securitized investment vehicles such as commercial mortgage-back securities (CMBS), interest-only CMBS, and collateralized mortgage pass-through bonds (CMOs) backed by U.S. government agencies, such as the Federal National Mortgage Association (Fannie Mae). They believed that these securities were trading at attractive levels versus traditional mortgage pass-through bonds. In the wake of the credit crisis and the recession, many holdings underper-formed, but the co-managers believe that these securities still offer the potential for substantial returns once the market environment stabilizes.

The Federal Reserve Board’s (the Fed) aggressive cuts in the federal funds rate, combined with the flight to quality, resulted in a steeper yield curve, as demand for longer-term bonds weakened. As a result, the fund’s yield-curve positioning — emphasizing short-term versus long-term bonds — was positive for performance. The co-managers’ decision to underweight and effectively diversify the fund’s exposure to corporate bonds was also beneficial — helping it to sidestep numerous defaults, particularly in the financials sector.

2


The biggest equity detractors to performance for the period were companies with exposure to debt, including the yellow pages company R.H. Donnelley Corp., Lehman Brothers, and Wachovia, all of which were sold by period-end. By the end of 2008, financial holdings, which are an important sector in the value-investing universe and an attractive source of dividend income for the fund, were focused on the larger, high-quality companies with less exposure to the mortgage crisis, including JPMorgan and Wells Fargo. With economic growth slowing, the co-managers prudently reduced the fund’s exposure to consumer cyclical stocks. The more defensive consumer staples holdings, such as General Mills, performed relatively well. Management also increased the fund’s exposure to energy stocks during the second half of the period, given their attractive prices and favorable supply-and-demand trends.

Management believes that investors should remain patient and maintain a long-term perspective. Eventually the capital markets will stabilize, and investors will begin to capitalize on the value embedded in them.

The fund may invest a portion of its assets in small and/or mid-size companies. Such investments increase the risk of greater price fluctuations. The use of derivatives involves special risks and may result in losses. The fund may have a significant portion of its holdings in bonds. 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. Value investing seeks underpriced stocks, but there is no guarantee that a stock’s price will rise.


The Barclays Capital Aggregate Bond Index is an unmanaged index of U.S. investment-grade fixed-income securities. The George Putnam Blended Index is an unmanaged index administered by Putnam Management, 60% of which is the Russell 1000 Value Index and 40% of which is the Barclays Capital Aggregate Bond Index. The S&P 500/Citigroup Value Index is an unmanaged, capitalization-weighted index of large-cap stocks chosen for their value orientation. The Russell 1000 Value Index is an unmanaged index of those companies in the large-cap Russell 1000 Index chosen for their value orientation. It has replaced the S&P 500/Citigroup Value Index as the fund’s primary benchmark. Indexes assume reinvestment of all distributions and do not account for fees. Securities and performance of a fund and an index will differ. It is not possible to invest directly in an index.

Understanding your VT fund’s expenses

As an investor in a variable annuity product that in turn invests in a registered investment company, you pay ongoing expenses, such as management fees, distribution fees (12b-1 fees), and other expenses. Using the information in this section, 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), which are not shown in this section and would result in higher total expenses. In addition, charges and expenses at the insurance company separate account level are not reflected. For more information, see your fund’s prospectus or talk to your financial representative.

Review your VT fund’s expenses

The first two columns in the table in this section, containing expense and value information, show the expenses you would have paid on a $1,000 investment in your fund from July 1, 2008 to December 31, 2008. They also show how much a $1,000 investment would be worth at the close of the period, assuming actual returns and expenses. You may use the information in this part of the table to estimate the expenses that you paid over the period. Simply divide your account value by $1,000, and then multiply the result by the number in the first line (“Expenses paid per $1,000”) for the class of shares you own (using the first two class IA and class IB columns only).

Compare your fund’s expenses with those of other funds

You can also use this table to compare your fund’s expenses with those of other funds. The Securities and Exchange Commission (SEC) has established guidelines to help investors assess fund expenses. Per these guidelines, the two right-hand columns of the table show 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 VT funds and mutual funds. All shareholder reports of mutual funds and funds serving as variable annuity vehicles 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.

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 December 31, 2008. The expense ratio may differ for each share class. 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. During portions of the period, the fund limited expenses; had it not done so, expenses would have been higher.

† Putnam keeps fund expenses below the Lipper peer group average expense ratio by limiting our fund expenses if they exceed the Lipper average.The Lipper average is a simple average of expenses of the mutual funds serving as investment vehicles for variable insurance products in the peer group that excludes 12b-1 fees as well as any expense offset and brokerage/service arrangements that may reduce subaccount expenses.To facilitate the comparison in this presentation, Putnam has adjusted the Lipper average to reflect the 12b-1 fees carried by class IB shares. Investors should note that the other funds in the peer group may be significantly smaller or larger than the fund, and that an asset-weighted average would likely be lower than the simple average. Also, the fund and Lipper report expense data at different times and for different periods.The fund’s expense ratio shown here is annualized data for the most recent six-month period, while the quarterly updated Lipper average is based on the most recent fiscal year-end data available for the peer group funds as of 12/31/08.

Trustee approval of management contract

General conclusions

The Board of Trustees of the Putnam funds oversees the management of the funds in Putnam Variable Trust and, as required by law, determines annually whether to approve the continuance of each fund’s management contract with Putnam Investment Management (“Putnam Management”) and, in respect of certain funds in Putnam Variable Trust, the sub-management contract between Putnam Management’s affiliate, Putnam Investments Limited (“PIL”), and Putnam Management. In 2008, the Board of Trustees also approved a new sub-management contract, in respect of certain funds in Putnam Variable Trust, between PIL and Putnam Management, and a new sub-advisory contract, in respect of certain funds in Putnam Variable Trust, among Putnam Management, PIL, and another affiliate, The Putnam Advisory Company (“PAC”).

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 2008, the Contract Committee met several times to consider the information provided by Putnam Management and other information developed with the assistance of the Board’s independent counsel and independent staff. The Contract Committee reviewed and discussed key aspects of this information with all of the Independent Trustees. The Contract Committee recommended, and the Independent Trustees approved, the continuance of the funds’ management contract, and in respect of certain funds in Putnam Variable Trust, the sub-management and sub-advisory contracts, effective July 1, 2008. (Because PIL and PAC are affiliates of Putnam Management and Putnam Management remains fully responsible for all services provided by PIL and PAC, the Trustees have not evaluated PIL and PAC as separate entities, except as otherwise indicated below, and all subsequent references to Putnam Management below should be deemed to include reference to PIL and PAC as necessary or appropriate in the context.)

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

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

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

These conclusions were based on a comprehensive consideration of all information provided to the Trustees, were subject to the continued application of certain expense reductions and waivers and other considerations noted below, 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 the funds in Putnam Variable Trust 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

5


in Putnam Management’s operating costs or responsibilities, or changes in competitive practices in the mutual fund industry — that suggest that consideration of fee changes might be warranted. The Trustees concluded that the circumstances did not warrant changes to the management fee structure of the funds in Putnam Variable Trust, which had been carefully developed over the years, re-examined on many occasions and adjusted where appropriate. In this regard, the Trustees also noted that shareholders of the funds in Putnam Variable Trust voted in 2007 to approve new management contracts containing an identical fee structure. 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., the fund ranked in the following percentiles in management fees and total expenses (less any applicable 12b-1 fees and excluding charges and expenses at the insurance company separate account level) as of December 31, 2007 (the first percentile being the least expensive funds and the 100th percentile being the most expensive funds).

  Actual Management Total Expenses
  Fee (percentile) (percentile)

Putnam VT The George Putnam Fund of Boston 62nd 41st

(Because a fund’s custom peer group is smaller than its 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 initially implemented in January 2004. The Trustees have received a commitment from Putnam Management and its parent company to continue this program through at least June 30, 2009. These expense limitations give effect to a commitment by Putnam Management that the expense ratio of each open-end fund would be no higher than the average expense ratio of the competitive funds included in the fund’s relevant Lipper universe (exclusive of any applicable 12b-1 charges in each case). The Trustees observed that this commitment to limit fund expenses has served shareholders well since its inception.

In order to ensure that the expenses of the Putnam funds continue to meet evolving competitive standards, the Trustees requested, and Putnam Management agreed, to extend for the twelve months beginning July 1, 2008, an additional expense limitation for certain funds at an amount equal to the average expense ratio (exclusive of 12b-1 charges) of a custom peer group of competitive funds selected by Lipper to correspond to the size of the fund. This additional expense limitation will be applied to those open-end funds that had above-average expense ratios (exclusive of 12b-1 charges) based on the custom peer group data for the period ended December 31, 2007. This additional expense limitation will not apply to your fund.In addition, the Trustees devoted particular attention to analyzing the Putnam funds’ fees and expenses relative to those of competitors in fund complexes of comparable size and with a comparable mix of asset categories. The Trustees concluded that this analysis did not reveal any matters requiring further attention at the current time.

In addition, the Trustees devoted particular attention to analyzing the Putnam funds’ fees and expenses relative to those of competitors in fund complexes of comparable size and with a comparable mix of asset categories. The Trustees concluded that this analysis did not reveal any matters requiring further attention at the current time.

Economies of scale. The funds in Putnam Variable Trust currently have the benefit of breakpoints in their management fees 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 the fund grows in size and crosses specified asset thresholds. Conversely,

6


if 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 in Putnam Variable Trust represented an appropriate sharing of economies of scale at current asset levels.

In connection with their review of the management fees and total expenses of the Putnam funds, the Trustees also reviewed the costs of the services to be provided and profits to be realized by Putnam Management and its affiliates from the relationship with the funds. This information included trends in revenues, expenses and profitability of Putnam Management and its affiliates relating to the investment management and distribution services provided to the funds. In this regard, the Trustees also reviewed an analysis of Putnam Management’s revenues, expenses and profitability with respect to the funds’ management contracts, allocated on a fund-by-fund basis.

Investment performance

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

While the Trustees noted the satisfactory investment performance of certain Putnam funds, they considered the disappointing investment performance of many funds in recent periods, particularly over periods in 2007 and 2008. They 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 taken steps to strengthen its investment personnel and processes to address areas of underperformance, including recent efforts to further centralize Putnam Management’s equity research function. In this regard, the Trustees took into consideration efforts by Putnam Management to improve its ability to assess and mitigate investment risk in individual funds, across asset classes, and across the complex as a whole. The Trustees indicated their intention to continue to monitor performance trends to assess the effectiveness of these efforts and to evaluate whether additional changes to address areas of underperformance are warranted.

In the case of your fund, the Trustees considered the Lipper peer group percentile rankings for the fund’s class IA share cumulative total return performance results at net asset value for the one-year, three-year and five-year periods ended December 31, 2007. This information is shown in the following table. (Because of the passage of time, these performance results may differ from the performance results for more recent periods shown elsewhere in this report. In addition, results do not reflect charges and expenses at the insurance company separate account level.) Where applicable, the table also shows the number of funds in the peer group for the respective periods; this number is indicated in parentheses following the percentile. Note that the first percentile denotes the best performing funds and the 100th percentile denotes the worst performing funds. Past performance is no guarantee of future returns.

The Trustees noted the disappointing performance for your fund for the one-year, three-year and five-year periods ended December 31, 2007. In this regard, the Trustees considered that, similar to the experience of certain other Putnam funds with exposure to the large-cap equity space, this fund’s performance would have been materially better over these periods but for the performance of a limited number of portfolio choices in the financial sector that experienced extreme distress in the market turmoil that began in the summer of 2007. In addition, following leadership and portfolio management team changes, Put-nam Management continues to make efforts to enhance the strength of the Large Cap Equities team, and Putnam Management has centralized the equity research structure. These changes were made to strengthen the investment process, which focuses on a blend of quantitative techniques and fundamental analysis, and to enhance the performance potential for Putnam funds with exposure to the large-cap equity space.

* * *

As a general matter, the Trustees believe 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 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 Putnam Variable Trust. 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 considered changes made in 2008, at Putnam Management’s request, to the Putnam funds’ brokerage allocation policy, which expanded the permitted categories of brokerage and research services payable with soft dollars and increased the permitted soft dollar allocation to third-party services over what had been authorized in previous years. The Trustees indicated their continued intent to monitor the potential benefits associated with the allocation of fund brokerage and trends in industry practice to ensure that the principle of seeking “best price and execution” remains paramount in the portfolio trading process.

The Trustees’ annual review of Putnam Variable Trust’s management contract arrangements also included the review of its distributor’s contract and distribution plan with Putnam Retail Management Limited Partnership and the investor servicing agreement with Putnam Fiduciary Trust Company (“PFTC”), each of which provides benefits to affiliates of Putnam Management. In the case of the investor servicing agreement, the Trustees considered that certain shareholder servicing functions were shifted to a third-party service provider by PFTC in 2007.

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 comparisons 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 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 different asset classes are typically 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 the funds in Putnam Variable Trust are reasonable.

More recent Lipper percentile rankings are shown for the fund in the following table. Note that this information was not available to the Trustees when they approved the continuance of the funds’ management contract. The table shows the Lipper peer group percentile rankings of the fund’s class IA share total return performance at net asset value. These rankings were determined on an annualized basis and are for the one-year, five-year, and ten-year periods ended on the most recent calendar quarter (December 31, 2008). Where applicable, the table also shows the fund’s rank among the total number of funds in its peer group for the respective periods; this information is indicated in parentheses following the percentile.

Approval of the Sub-Management Contract between Putnam Management and Putnam Investments Limited and the Sub-Advisory Contract among Putnam Management, Putnam Investments Limited andThe Putnam Advisory Company

In 2008, the Trustees approved a new sub-management contract between Putnam Management and PIL in respect of certain funds in Putnam Variable Trust, under which PIL’s London office would begin managing a separate portion of the assets of certain funds. Also in 2008, the Trustees approved a new sub-advisory contract among Putnam Management, PIL and PAC in respect of certain funds in Putnam Variable Trust, under which PAC’s Tokyo branch would begin providing non-discretionary investment services to certain funds, and PAC’s Singapore branch would begin providing discretionary investment management services to certain funds. The applicable funds and their respective sub-management and/or sub-advisory contracts are listed in the table below, along with the Trustee approval date, the effective date of the services, and the type of PAC services provided, if applicable. The Contract Committee reviewed information provided by Putnam Management, PIL and PAC and, upon completion of this review, recommended, and the Independent Trustees and the full Board of Trustees approved, the sub-management contract and the sub-advisory contract in respect of the funds in Putnam Variable Trust listed below.

The Trustees considered numerous factors they believed relevant in approving your fund’s sub-management and sub-advisory contracts, including Putnam Management’s belief that the interest of shareholders would be best served by utilizing investment professionals in PIL’s London office and PAC’s Tokyo and Singapore offices to manage a portion of

9


certain funds’ assets and PIL’s and PAC’s expertise in managing assets invested in European and Asian markets, respectively. The Trustees also considered that applicable securities laws require a sub-advisory relationship among Putnam Management, PIL and PAC in order for Putnam’s investment professionals in London, Tokyo and Singapore to be involved in the management of your fund. The Trustees noted that Putnam Management, and not your fund, would pay the sub-management fee to PIL for its services, that Putnam Management and/or PIL, but not your fund, would pay the sub-advisory fee to PAC for its services, and that the sub-management and sub-advisory relationships with PIL and PAC, respectively, will not reduce the nature, quality or overall level of service provided to the applicable funds.

Report of Independent Registered Public Accounting Firm

To the Trustees of Putnam Variable Trust and Shareholders of
Putnam VT The George Putnam Fund of Boston:

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 VT The George Putnam Fund of Boston (the “fund”) at December 31, 2008, 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 December 31, 2008 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

* Payments related to the reference debt are made upon a credit default event.

** Upfront premium is based on the difference between the original spread on issue and the market spread on day of execution.

*** Ratings are presented for credit default contracts in which the fund has sold protection on the underlying referenced debt. Ratings for an underlying index represent the average of the ratings of all the securities included in that index. The Moody’s or Standard & Poor’s ratings are believed to be the most recent ratings available at December 31, 2008. (F) Is valued at fair value following procedures approved by the Trustees. Securities may be classified as a Level 2 or Level 3 for FASB 157 disclosures based on securities valuation inputs.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157). SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. While the adoption of SFAS 157 does not have a material effect on the fund’s net asset value, it does require additional disclosures about fair value measurements.The Standard establishes a three-level hierarchy for disclosure of fair value measurements.The valuation hierarchy is based upon the transparency of inputs to the valuation of the fund’s investments. The three levels are defined as follows:

Level 1 — Valuations based on quoted prices for identical securities in active markets.

Level 2 — Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3 — Valuations based on inputs that are unobservable and significant to the fair value measurement.

The following is a summary of the inputs used to value the fund’s net assets as of December 31, 2008:

            Investments in           financial

PUTNAM VARIABLE TRUST

Notes to Financial Statements
December 31, 2008

NOTE 1
SIGNIFICANT ACCOUNTING POLICIES

Putnam VT The George Putnam Fund of Boston (the “fund”), a Massachusetts business trust, is one of a series of funds comprising Putnam Variable Trust (the “Trust”), which is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The fund seeks a balanced investment producing both capital growth and current income by investing primarily in value-oriented stocks of large companies and government, corporate and mortgage-backed bonds. The fund may invest a significant portion of its assets in securitized debt instruments, including mortgage-backed and asset-backed investments. The yields and values of these investments are sensitive to changes in interest rates, the rate of principal payments on the underlying assets and the market’s perception of the issuers. The market for these investments may be volatile and limited, which may make them difficult to buy or sell.

The fund offers class IA and class IB shares of beneficial interest. Class IA shares are offered at net asset value and are not subject to a distribution fee. Class IB shares are offered at net asset value and pay an ongoing distribution fee, which is identified in Note 2.

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. If the fund were liquidated, shares of each class would receive their pro-rata share of the net assets of the fund. 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’s management team 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 finan-cial 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, a wholly-owned subsidiary of Putnam Investments, 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 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

50


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. To the extent a pricing service or dealer is unable to value a security or provides a valuation which Putnam Management does not believe accurately reflects the security’s fair value, the security will be valued at fair value by Putnam Management. Certain investments, including certain restricted and illiquid securities and derivatives, are also valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees. Certain securities may be valued on the basis of a price provided by a single source. 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 “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 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 counterparty. Putnam Management is responsible for determining that the value of these underlying securities is at all times at least equal to the resale price, including accrued interest.

D) Security transactions and related investment income Security transactions are recorded on the trade date (the date the order to buy or sell is executed). Gains or losses on securities sold are determined on the identi-fied 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 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) Stripped securities The fund may invest in stripped securities which represent a participation in securities that may be structured in classes with rights to receive different portions of the interest and principal. Interest-only securities receive all of the interest and principal-only securities receive all of the principal. If the interest-only securities experience greater than anticipated prepayments of principal, the fund may fail to recoup fully its initial investment in these securities. Conversely, principal-only securities

51


increase in value if prepayments are greater than anticipated and decline if prepayments are slower than anticipated. The market value of these securities is highly sensitive to changes in interest rates.

F) 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 is 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.

G) 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 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. 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.

H) Futures and options contracts The fund may use futures and options contracts to hedge against changes in the values of securities the fund owns, owned 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

52


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.

I) 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 finan-cial 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 an unrealized gain or loss. Payments received or made are recorded as realized gains or losses. Certain total return swap contracts may include extended effective dates. Payments related to these swap contracts are 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.

J) Interest rate swap contracts The fund may enter into interest rate swap contracts, which are arrangements between two parties to exchange cash flows based on a notional principal amount, to manage the fund’s exposure to interest rates. An interest rate swap can be purchased or sold with an upfront premium. An upfront payment received by the fund is recorded as a liability on the fund’s books. An upfront payment made by the fund is recorded as an asset on the fund’s books. Interest rate swap 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 an unrealized gain or loss. Payments received or made are recorded as realized gains or losses. Certain interest rate swap contracts may include extended effective dates. Payments related to these swap contracts are 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 if the counterparty defaults on its obligation to perform. Risk of loss may exceed amounts recognized on the Statement of assets and liabilities. Interest rate swap contracts outstanding at period end, if any, are listed after the fund’s portfolio.

K) Credit default contracts The fund may enter into credit default contracts to provide a measure of protection against risk of loss following a default, or other credit event in respect of issuers within an underlying index or a single issuer, or to gain credit exposure to an underlying index or issuer. In a credit default contract, the protection buyer typically makes an up front payment and a periodic stream of payments to a counterparty, the protection seller, in exchange for the right to receive a contingent payment upon the occurrence of a credit event on the reference obligation or all other equally ranked obligations of the reference entity. Credit events are contract specific but may include bankruptcy, failure to pay, restructuring and obligation acceleration. 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

53


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 an unrealized gain or loss. Upon the occurrence of a credit event, the difference between the par value and market value of the reference obligation, net of any proportional amount of the upfront payment, is recorded as a realized gain or loss.

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 or 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 the underlying reference obligations. In certain circumstances, the fund may enter into offsetting credit default contracts which would mitigate its risk of loss. Risks of loss may exceed amounts recognized on the Statement of assets and liabilities.. The fund’s maximum risk of loss from counterparty risk, either as the protection seller or as the protection buyer, is the fair value of the contract. This risk is mitigated by having a master netting arrangement between the fund and the counterparty. Where the fund is a seller of protection, the maximum potential amount of future payments the fund may be required to make is equal to the notional amount of the relevant credit default contract. Credit default contracts outstanding, including their respective notional amounts at period end, if any, are listed after the fund’s portfolio.

L) TBA purchase commitments The fund may enter into “TBA” (to be announced) commitments to purchase securities for a fixed unit price at a future date beyond customary settlement time. Although the unit price has been established, the principal value has not been finalized. However, the amount of the commitments will not significantly differ from the principal amount. The fund holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the fund may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date, which risk is in addition to the risk of decline in the value of the fund’s other assets. Unsettled TBA purchase commitments are valued at fair value of the underlying securities, according to the procedures described under “Security valuation” above. The contract is marked to market daily and the change in market value is recorded by the fund as an unrealized gain or loss.

Although the fund will generally enter into TBA purchase commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the fund may dispose of a commitment prior to settlement if Putnam Management deems it appropriate to do so.

M)TBA sale commitments The fund may enter into TBA sale commitments to hedge its portfolio positions or to sell mortgage-backed securities it owns under delayed delivery arrangements. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, equivalent deliverable securities or an offsetting TBA purchase commitment deliverable on or before the sale commitment date, are held as “cover” for the transaction.

Unsettled TBA sale commitments are valued at the fair value of the underlying securities, generally according to the procedures described under “Security valuation” above. The contract is marked to market daily and the change in market value is recorded by the fund as an unrealized gain or loss. If the TBA sale commitment is closed through the acquisition of an offsetting TBA purchase commitment, the fund realizes a gain or loss. If the fund delivers securities under the commitment, the fund realizes a gain or a loss from the sale of the securities based upon the unit price established at the date the commitment was entered into. TBA sale commitments outstanding at period end, if any, are listed after the fund’s portfolio.

N) Dollar rolls To enhance returns, the fund may enter into dollar rolls (principally using TBAs) in which the

54


fund sells securities for delivery in the current month and simultaneously contracts to purchase similar securities on a specified future date. During the period between the sale and subsequent purchase, the fund will not be entitled to receive income and principal payments on the securities sold. The fund will, however, retain the difference between the initial sales price and the forward price for the future purchase. The fund will also be able to earn interest on the cash proceeds that are received from the initial sale, on settlement date. The fund may be exposed to market or credit risk if the price of the security changes unfavorably or the counterparty fails to perform under the terms of the agreement.

O) 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 December 31, 2008, the fund had no securities out on loan.

P) 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, as amended (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. The fund is subject to the provisions of FASB Interpretation No. 48, Accounting for Uncertainties in Income Taxes (FIN 48). FIN 48 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The fund did not have any unrecognized tax benefits in the accompanying financial statements. 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. Each of the fund’s federal tax returns for the prior three fiscal years remains subject to examination by the Internal Revenue Service.

At December 31, 2008, the fund had a capital loss carryover of $107,586,636 available to the extent allowed by the Code to offset future net capital gain, if any. This capital loss carryover will expire on December 31, 2016.

Q) 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/or permanent differences of losses on wash sale transactions, unrealized gains and losses on certain future contracts, income on swap contracts, interest only securities and redesignation of taxable income. 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 December 31, 2008, the fund reclassified $1,946,150 to decrease undistributed net investment income and $7 to decrease paid-in-capital, with a decrease to accumulated net realized losses of $1,946,157.

The tax basis components of distributable earnings as of

December 31, 2008 were as follows:

Unrealized appreciation $17,564,587
Unrealized depreciation (52,364,940)
 
Net unrealized depreciation (34,800,353)
Undistributed ordinary income 9,753,031
Capital loss carry forward (107,586,636)
Cost for federal income tax purposes $514,514,383

55


R) Expenses of the trust Expenses directly charged or attributable to any fund will be paid from the assets of that fund. Generally, expenses of the trust will be allocated among and charged to the assets of each fund on a basis that the Trustees deem fair and equitable, which may be based on the relative assets of each fund or the nature of the services performed and relative applicability to each fund.

S) Beneficial interest At December 31, 2008, insurance companies or their separate accounts were record owners of all but a de minimis number of the shares of the fund. Approximately 60.7% of the fund is owned by accounts of one group of insurance companies.

NOTE 2
MANAGEMENT FEE, ADMINISTRATIVE
SERVICES AND OTHER TRANSACTIONS

The fund pays Putnam Management 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: 0.65% of first $500 million of average net assets, 0.55% of the next $500 million, 0.50% of the next $500 million, 0.45% of the next $5 billion, 0.425% of the next $5 billion, 0.405% of the next $5 billion, 0.39% of the next $5 billion, and 0.38% thereafter.

Putnam Management has agreed to waive fees and reimburse expenses of the fund through June 30, 2009 to the extent necessary to ensure that the fund’s expenses do not exceed the simple average of the expenses of all 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 December 31, 2008, Putnam Management waived $151,966 of its management fee from the fund.

Effective November 30, 2008 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.

On September 26, 2008, the fund entered into an Agreement with another registered investment company (the “Purchaser”) managed by Putnam Management. Under the Agreement, the fund sold to the Purchaser the fund’s right to receive, in the aggregate, $538,710 in net payments from Lehman Brothers Special Financing, Inc. in connection with certain terminated derivatives transactions (the “Receivable”), in exchange for an initial payment plus (or minus) additional amounts based on the applicable Purchaser’s ultimate realized gain (or loss) on the Receivable. The Receivable will be offset against the funds net receivable from Lehman Brothers Special Financing, Inc. which is included in the Statement of assets and liabilities within the Payable for closed swap contracts. The Agreement, which is included in the Statement of assets and liabilities, is valued at fair value following procedures approved by the Trustees. All remaining payments under the Agreement will be recorded as realized gain or loss.

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

Custodial functions for the fund’s assets were provided by State Street Bank and Trust Company (“State Street”). 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 Putnam Fiduciary Trust Company (“PFTC”), which is an affiliate of Putnam Management, provided investor servicing agent functions to the fund through December 31, 2008. Subsequent to

56


December 31, 2008, these services were provided by Put-nam Investor Services, Inc., another affiliate of Putnam Management. Putnam Investor Services was paid a monthly fee for investor servicing at an annual rate of 0.03% of the fund’s average net assets. During the period ended December 31, 2008, the amounts incurred for investor servicing agent functions provided by PFTC are included in Investor servicing fees in the Statement of operations.

The fund has entered into expense offset arrangements with PFTC and State Street whereby PFTC’s and State Street’s fees are reduced by credits allowed on cash balances. The fund also reduced expenses through brokerage/service arrangements. For the year ended December 31, 2008, the fund’s expenses were reduced by $27,658 under the expense offset arrangements and by $14,668 under the brokerage/service arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of which $374, as a quarterly retainer, has been allocated to the fund, and an additional fee for each Trustees meeting attended. Trustees receive additional fees for attendance at certain committee meetings and industry seminars and for certain compliance-related matters. Trustees also are reimbursed for expenses they incur relating to their services as Trustees.

The fund has adopted a Trustee Fee Deferral Plan (the “Deferral Plan”) which allows the Trustees to defer the receipt of all or a portion of Trustees fees payable on or after July 1, 1995. The deferred fees remain invested in certain Putnam funds until distribution in accordance with the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension plan (the “Pension Plan”) covering all Trustees of the fund who have served as a Trustee for at least five years and were first elected prior to 2004. Benefits under the Pension Plan are equal to 50% of the Trustee’s average annual attendance and retainer fees for the three years ended December 31, 2005. The retirement benefit is payable during a Trustee’s lifetime, beginning the year following retirement, for the number of years of service through December 31, 2006. Pension expense for the fund is included in Trustee compensation and expenses in the Statement of operations. Accrued pension liability is included in Payable for Trustee compensation and expenses in the Statement of assets and liabilities. The Trustees have terminated the Pension Plan with respect to any Trustee first elected after 2003.

The fund has adopted a distribution plan (the “Plan”) with respect to its class IB shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The purpose of the Plan is to compensate Putnam Retail Management Limited Partnership, a wholly-owned subsidiary of Put-nam Investments, LLC and Putnam Retail Management GP, Inc., for services provided and expenses incurred in distributing shares of the fund. The Plan provides for payment by the fund to Putnam Retail Management Limited Partnership at an annual rate of up to 0.35% of the average net assets attributable to the fund’s class IB shares. The Trustees have approved payment by the fund at an annual rate of 0.25% of the average net assets attributable to the fund’s class IB shares.

INVESTMENT IN PUTNAM PRIME MONEY

NOTE 6
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 7
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 in connection with excessive short-term trading in Putnam funds. Distribution of payments from Putnam Management to certain open-end Putnam funds and their shareholders is expected to be completed in the next several months. These allegations and related matters have served as the general basis for certain lawsuits, including purported class action

lawsuits against Putnam Management and, in a limited number of cases, some Putnam funds. Putnam Management believes that these lawsuits will have no material adverse effect on the funds or on Putnam Management’s ability to provide investment management services. In addition, Putnam Management has agreed to bear any costs incurred by the Putnam funds as a result of these matters.

NOTE 8
NEW ACCOUNTING PRONOUNCEMENT

In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (“SFAS 161”) — an amendment of FASB Statement No. 133, was issued and is effective for fiscal years and interim periods beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about how and why an entity uses derivative instruments and how derivative instruments affect an entity’s financial position. Putnam Management is currently evaluating the impact the adoption of SFAS 161 will have on the fund’s financial statement disclosures.

NOTE 9
MARKET AND CREDIT RISK

In the normal course of business the fund trades financial instruments and enters into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the contracting party to the transaction to perform (credit risk). The fund may be exposed to additional credit risk that an institution or other entity with which the funds have unsettled or open transactions will default.

NOTE 10
OTHER ITEMS

The fund is a party to ISDA (International Swap and Derivatives Association, Inc.) Master Agreements with certain counterparties that govern OTC derivative and foreign exchange contracts entered into from time to time. As of December 31, 2008, due to a decrease in the fund’s net asset value during the year, such counterparties were entitled to elect, but had not yet elected, to terminate

59


early, and cause settlement of all derivative and foreign exchange contracts outstanding under the applicable Master Agreements, including the payment by the fund of any losses and costs resulting from such early termination, as reasonably determined by such counterparty. Any decision by the counterparty to elect early termination could impact the fund’s future derivative activity. At December 31, 2008, the fund had net unrealized gains/(losses) on derivative contracts subject to the Master Agreements of $6,210,613 and $(23,507,335), respectively. The fund intends to seek a waiver of, or other relief from this provision, from the counterparties.

Item 2. Code of Ethics:

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

(c) In May 2008, the Code of Ethics of Putnam Investment Management, LLC was updated in its entirety to include the amendments adopted in August 2007 as well as a several additional technical, administrative and non-substantive changes.

Item 3. Audit Committee Financial Expert:

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

Item 4. Principal Accountant Fees and Services:

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

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

December 31, 2008 $132,678 $-- $5,743 $421*

* Includes fees of $421 and $310 billed by the fund’s independent auditor to the fund for procedures necessitated by regulatory and litigation matters for the fiscal years ended December 31, 2008 and December 31, 2007, respectively. These fees were reimbursed to the fund by Putnam Investment Management, LLC (“Putnam Management”).

For the fiscal years ended December 31, 2008 and December 31, 2007, the fund’s independent auditor billed aggregate non-audit fees in the amounts of $177,710 and $81,152 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-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 the proposed market timing distribution.

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

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

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