ITEM 1: REPORT TO SHAREHOLDERS The Semi-annual Report is attached. <Page> [GRAPHIC] STATE STREET RESEARCH [GRAPHIC] Asset Allocation Fund September 30, 2004 Semiannual Report to Shareholders Table of Contents 3 Performance Discussion 4 About Your Fund Expenses 5 Portfolio Holdings 18 Financial Statements 23 Financial Highlights 25 Trustees and Officers FROM THE CHAIRMAN State Street Research The U.S. economy grew at a solid pace during the six-month period from April 1, 2004 to September 30, 2004. Gross Domestic Product (GDP), a common measure of economic growth, rose at a pace of more than 3.5% for the first half of 2004. Estimates for second half suggest that the pace of growth could have picked up somewhat, as the US economy remains on solid ground. Consumer confidence wavered early in the period as the number of new jobs added to the economy fell below expectations. When the job picture brightened in April and May, consumer confidence tracked higher. More than 1.2 million jobs were added to the U.S. economy in the spring, and the quality of new jobs improved, as reported by the U.S. Labor Department. However, caution returned on disappointing jobs reports in July and August and consumer confidence pulled back. Yet, consumers continued to fuel the economy, pumping dollars into the retail and housing markets. Sales of new and existing homes soared as homebuyers anticipated higher mortgage rates ahead. Corporate profits continued to rise, making it easier for companies to increase spending, especially on information technology, electronic equipment and new jobs. As the period wore on, it became clear that the days of record-low short-term interest rates were coming to an end. In June, the Federal Reserve Board raised the federal funds rate from 1.0% to 1.25%. The Fed raised this key short-term rate to 1.5% in August and to 1.75% in September. These increases had little or no impact on the financial markets because they had been widely anticipated and because the Fed has signaled that it will take a measured approach to raising rates as the economic recovery matures. Stocks Stumble as Bonds Edge Higher After a relatively positive start to the calendar year, a host of worries stopped the major stock market indexes in their tracks. Investors grew more cautious about interest rates, rising energy prices, the threat of terrorist attacks and the outcome of the presidential election and stocks retreated. Value stocks held up considerably better than growth stocks. The energy sector was the stock market's strongest performer. High-yield bonds continued to lead the bond market. Most other sectors of the bond market eked out modest positive returns as the yield on the benchmark 10-year U.S. Treasury bond moved lower in the final months of the period. Yields and bond prices move in opposite directions. Looking Ahead Any time the financial markets deliver negative returns, it is disheartening for investors. However, the seeds of a new market rally are often sown in periods of weakness and decline. With a diversified portfolio and a long-term perspective on the markets, it is easier to weather periods of volatility--and more likely that you may reap the potential benefits in better times. We urge you to talk to your investment professional about your investment plan. And we look forward to helping you achieve your long-term financial goals. Sincerely, /s/ Richard S. Davis Richard S. Davis Chairman September 30, 2004 2 PERFORMANCE Discussion as of September 30, 2004 How State Street Research Asset Allocation Fund Performed State Street Research Asset Allocation Fund (Class A shares, without sales charge) returned -0.94% for the six-month period ended September 30, 2004. It underperformed its peer group, the Lipper Flexible Portfolio Funds Average, which was -0.72% for the period. The fund also underperformed the S&P 500/Lehman Brothers Blended Index, which returned -0.19% for the same period. Reasons for the Fund's Performance The broad equity markets struggled during the six-month period, with growth stocks experiencing the largest downturn. Bonds recovered during the third calendar quarter, resulting in positive returns for the year to date. Within the equity portion of the portfolio, small-cap growth stocks had the largest negative impact on returns because the sector suffered the largest declines during the period. However, an increased exposure to large-cap value shares helped the fund's return as value stocks led the market. In addition, the fund's inflation-sensitive holdings aided return, as they benefited from rising oil prices. Finally, a modest international equity allocation was detrimental, as the Japanese stock market continued to lose ground. In the fixed income portfolio, high-yield and emerging markets exposure had the greatest positive impact on returns. The high-yield sector benefited from a recovery in corporate earnings and a decline in the expected default rate to 3.0%. The outlook for emerging markets debt also improved. Meanwhile, we slightly increased our high-grade bond allocation, which helped performance. Looking Ahead We continue to emphasize equities over bonds, ending the period with a 63% stocks/37% bonds allocation. That represents a slight decrease in our exposure to equities and a slight increase in bonds, reflecting our view that corporate profit growth has decelerated and the stock market outlook remains uncertain. In the equity portfolio, we continue to favor large-cap stocks over small-cap, and value issues over growth. We believe that business prospects for growth stocks, especially in the technology area, remain weak, and we continue to find investment opportunities among value stocks. The fund has maintained its modest position in international equities. Within fixed income, we remain invested in both high-yield and emerging markets debt, as we believe they offer the highest return potential. A Word about Risk When investing in stocks, the fund may experience sudden or unpredictable drops in value and periods of lackluster performance. When investing in bonds, the fund takes on the risks of bond investing, including the tendency for bond prices to fall when interest rates rise. Investments in foreign derivative securities are subject to economic and currency risk. The fund may not correctly anticipate the relative performance of different asset categories over specific time periods. Because financial markets and mutual fund strategies are constantly evolving, it is possible that the fund's holdings, market stance, outlook for various industries or securities and other matters discussed in this report have changed since this information was prepared. Portfolio changes should not be considered recommendations for action by individual investors.

Current performance may be lower or higher than the performance data quoted herein. For the most recent month-end performance results, visit our website at www.ssrfunds.com. The fund's share price, yield and return will fluctuate, and you may have a gain or loss when you sell your shares. All returns assume reinvestment of capital gains distributions and income dividends at net asset value. The returns shown do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Average annual total return without sales charge does not reflect the maximum applicable sales charges. If the applicable sales charges were deducted, performance results would be lower. Average Annual Total return at maximum applicable sales charge reflects a maximum 5.75% Class A share front-end sales charge, or 5% Class B or B(1) share or 1% Class C share contingent deferred sales charge, where applicable. Performance for Class B(1) shares reflects Class B share performance through December 31, 1998, and Class B(1) performance thereafter. If the returns for Class B(1) shares had reflected their current service/distribution (Rule 12b-1) fees for the entire period, these returns would have been lower. Class S shares, offered without sales charge, are available through certain employee benefit plans and special programs. The Lipper Flexible Portfolio Funds Average shows the performance of a category of mutual funds with similar goals. The Lipper average shows you how well the fund has done compared to competing funds. The S&P 500/Lehman Blended Index is an index created by State Street Research. The index is comprised of 60% of the performance of the S&P 500 Index and 40% of the performance of the Lehman Brothers Aggregate Bond Index. The S&P 500 Index (officially the "Standard & Poor's 500 Composite Stock Price Index") is an unmanaged index of 500 U.S. stocks. The Lehman Brothers Aggregate Bond Index is a market value-weighted index of investment-grade, fixed-rate debt issues, including government, corporate, asset-backed and mortgage-backed securities, with maturities of one year or more. The indexes are unmanaged and do not take transaction charges into consideration. It is not possible to invest directly in an index.

About Your Fund Expenses As a fund shareholder, you incur two types of costs: (1) Transaction costs, which include sales charges, and (2) ongoing expenses, which include management fees, service/distribution fees (12b-l) and "other" expenses. The examples below illustrate the ongoing cost in dollars of investing in the fund and allow you to compare these costs with the expenses of other funds. The examples are based on a $1,000 investment at the beginning of the period and held for the entire period from March 31, 2004 to September 30, 2004. Actual Fund Return is based on the fund's actual return and expenses. To estimate the ongoing expenses you paid during the entire period shown, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number shown for your fund under the column "Expenses Paid during the Period". Hypothetical 5% Return is based on the fund's actual expense ratio and an assumed rate of 5% per year before expenses. Please note that the return used is not the fund's actual return; therefore, this information may not be used to estimate your actual ending balance and expenses paid during the period. To compare your fund's ongoing expenses with those of other funds, simply compare this 5% hypothetical example with the hypothetical examples shown in the shareholder reports of other funds. Please note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect transactional expenses such as sales charges, which would result in higher total expenses. It should also be noted that, for certain funds, expenses have been subsidized or reduced through expense offset arrangements, which reduces costs for shareholders. Generally, the fund expects that the expense subsidy or expense offset arrangement will continue although there is no guarantee that it will. Please see the fund's prospectus for more information.

The Trust consists presently of two separate funds: State Street Research Asset Allocation Fund and State Street Research High Income Fund. The investment objective of the fund is to seek a high total return while attempting to limit investment risk and preserve capital. To achieve its investment objective, the fund uses an asset allocation strategy, investing in varying percentages of its portfolio in three major categories: stocks, bonds and, to a lesser extent, money market instruments. Drawing on its analysis of financial trends and market conditions, the investment manager monitors and adjusts those allocations from time to time. The fund has wide flexibility in the relative weightings given to each category; however, it intends to remain diversified across categories. The fund offers five classes of shares. Class A shares are subject to an initial sales charge of up to 5.75% and pay annual service and distribution fees equal to 0.30% of average daily net assets. Class B(1) shares pay annual service and distribution fees of 1.00% and automatically convert into Class A shares (which pay lower ongoing expenses) at the end of eight years. Class B(1) shares are subject to a contingent deferred sales charge on certain redemptions made within six years of purchase. Class B shares are offered only to current shareholders through reinvestment of dividends and distributions or through exchanges from existing Class B accounts of State Street Research funds. Currently, the annual service and distribution fees paid by Class B shares have been voluntarily reduced to 0.00%. Class B shares automatically convert into Class A shares at the end of eight years. Class B shares are subject to a contingent deferred sales charge on certain redemptions made within five years of purchase. Class C shares are subject to a contingent deferred sales charge of 1.00% on any shares redeemed within one year of their purchase, and also pay annual service and distribution fees of 1.00%. Class S shares are only offered through certain retirement accounts, advisory accounts of State Street Research & Management Company (the "Adviser"), an investment management subsidiary of MetLife, Inc. ("MetLife"), and special programs. No sales charge is imposed at the time of purchase or redemption of Class S shares. Class S shares do not pay any service or distribution fees. The fund's expenses are borne prorata by each class, except that each class bears expenses, and has exclusive voting rights with respect to provisions of the plans of distribution, related specifically to that class. Income, expenses (other than service and distribution fees), and unrealized and realized gains or losses on investments are allocated to each class of shares based on its relative net assets. The Trustees declare separate dividends on each class of shares. The following significant accounting policies are consistently followed by the fund in preparing its financial statements, and such policies are in conformity with accounting principles generally accepted in the United States of America. A. Investment Valuation Values for listed equity securities reflect final sales on national securities exchanges quoted prior to the close of the New York Stock Exchange. Over-the-counter securities quoted on the National Association of Securities Dealers Automated Quotation ("Nasdaq") system are valued at closing prices supplied through such system. If not quoted on the Nasdaq system, such securities are valued at prices obtained from independent brokers. In the absence of recorded sales, valuations are at the mean of the closing bid and asked quotations. Fixed income securities are valued by a pricing service, which utilizes market transactions, quotations from dealers and various relationships among securities in determining value. Short-term securities maturing within sixty days are valued at amortized cost. In the event that the market quotations for a portfolio instrument are not deemed to be readily available, the Investment Adviser's Valuation Committee determines the fair value for such portfo- The notes are an integral part of the financial statements. State Street Research Asset Allocation Fund 19 lio instrument. The fair value of any such portfolio instruments are determined based upon a consideration of all available facts and information. The fair valuation of a restricted portfolio instrument reflects the inherent worth of the portfolio instrument, without regard to the restrictive feature, adjusted for any diminution in value resulting from the restrictive feature. The Investment Adviser and the Custodian also monitor domestic and foreign markets and news information for any developing events that may have an impact on the valuation of portfolio instruments. Such monitoring includes general market news and financial market information sources currently utilized in making investment decisions, trading and investment personnel located abroad, foreign regional brokers, and/or foreign custodians. The value assigned to these securities is based upon available information at the time, and does not necessarily represent the amount which might ultimately be realized upon sale. B. Forward Contracts and Foreign Currencies The fund enters into forward foreign currency exchange contracts in order to hedge its exposure to changes in foreign currency exchange rates on its foreign portfolio holdings and to hedge certain purchase and sale commitments denominated in foreign currencies. A forward foreign currency exchange contract is an obligation by the fund to purchase or sell a specific currency at a future date, which may be any fixed number of days from the origination date of the contract. Forward foreign currency exchange contracts establish an exchange rate at a future date. These contracts are transferable in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. Risks may arise from the potential inability of a counterparty to meet the terms of a contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar. The aggregate principal amount of forward currency exchange contracts is recorded in the fund's accounts. All commitments are marked-to-market at the applicable transaction rates resulting in unrealized gains or losses. The fund records realized gains or losses at the time the forward contracts are extinguished by entry into a closing contract or by delivery of the currency. Neither spot transactions nor forward currency exchange contracts eliminate fluctuations in the prices of the fund's portfolio securities or in foreign exchange rates, or prevent loss if the price of these securities should decline. C. Security Transactions Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains or losses are reported on the basis of identified cost of securities delivered. As part of the custodian contract between the custodian bank and the fund, the custodian bank has a lien on the securities of the fund to the extent permitted by the fund's investment restriction to cover any advances made by the custodian bank for the settlement of securities purchased by the fund. At September 30, 2004, the payable to the custodian bank of $250,026 represents the amount due for cash advance for the settlement of the security purchased. D. Net Investment Income Net investment income is determined daily and consists of interest and dividends accrued and discount earned, less the estimated daily expenses of the fund. Interest income is accrued daily as earned. Dividend income is accrued on the ex-dividend date. All discounts/premiums are accreted/amortized. Certain fixed income and equity securities held by the fund pay interest or dividends in the form of additional securities (payment-in-kind securities). Interest income on payment-in-kind fixed income securities is recorded using the effective-interest method. The fund is charged for expenses directly attributable to it, while indirect expenses are allocated between both funds in the Trust. E. Dividends Dividends from net investment income are declared and paid or reinvested quarterly. Net realized capital gains, if any, are distributed annually, unless additional distributions are required for compliance with applicable tax regulations. Income dividends and capital gains distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. The difference is primarily due to differing treatments for wash sale deferrals. F. Federal Income Taxes No provision for federal income taxes is necessary because the fund has elected to qualify under Subchapter M of the Internal Revenue Code and its policy is to distribute all of its taxable income, including net realized capital gains, within the prescribed time periods. G. Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from these estimates. H. Securities Lending The fund may seek additional income by lending portfolio securities to qualified institutions. The fund will receive cash or securities as collateral in an amount equal to at least 100% of the current market value of any loaned securities plus accrued interest. By reinvesting any cash collateral it receives in these transactions, the fund could realize additional gains and losses. If the borrower fails to return the securities and the value of the collateral has declined during the term of the loan, the fund will bear the loss. At September 30, 2004, the value of the securities loaned and the value of collateral were $61,488,625 and $63,355,290 (consisting entirely of cash collateral invested in State Street Navigator Securities Lending Prime Portfolio), respectively. During the six months ended September 30, 2004, income from securities lending amounted to $79,641. I. Futures The fund may enter into futures contracts as a hedge against unfavorable market conditions and to enhance income. The fund will not purchase any futures contract if, after such purchase, more than one-third of net assets would be represented by long future contracts. The fund will limit its risks by entering into a futures position only if it appears to be a liquid investment. Upon entering into a futures contract, the fund deposits with the selling broker sufficient cash or U.S. government securities to meet the minimum "initial margin" requirements. Thereafter, the fund receives from or pays to the broker cash or U.S. government securities equal to the daily fluctuation in value of the contract ("variation margin"), which is recorded as 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 has opened and the value at the time it was closed. The potential risk to the fund is that the change in value of futures contracts may not correspond to the change in value of the hedged instruments. In addition, losses may arise in changes from 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. J. Options The fund may use options to hedge against changes in values of securities the fund owns or expects to purchase. Writing puts or buying calls tends to increase the fund's exposure to the underlying instrument and writing calls or buying puts tends to decrease the fund's exposure to the underlying instrument, or hedge other fund investments. For options purchased to hedge the fund's investments, the potential risk to the fund is that the change in value of options contracts may 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, or if the counter party is unable to perform. The maximum loss for purchased options is limited to the premium initially paid for the option. For options written by the fund, the maximum loss is not limited to the premium initially received for the option. Note 2 The Trust and the Adviser have entered into an agreement under which the Adviser earns monthly fees at an annual rate of 0.75% of the first $500 million of net assets annually, 0.70% of the next $500 million, and 0.65% of any amount over $1 billion. In consideration of these fees, the Adviser furnishes the fund with management, investment advisory, statistical and research facilities and services. The Adviser also pays all salaries, rent and certain other expenses of management. During the six 20 months ended September 30, 2004, the fees pursuant to such agreement amounted to $2,459,507. State Street Research Service Center, a division of State Street Research Investment Services, Inc., the Trust's principal underwriter (the "Distributor"), provides certain shareholder services to the fund such as responding to inquiries and instructions from investors with respect to the purchase and redemption of shares of the fund. In addition, MetLife receives a fee for maintenance of the accounts of certain shareholders who are participants in sponsored arrangements, such as employee benefit plans, through or under which shares of the fund may be purchased. Total shareholder service costs are allocated to each fund in the same ratios as the transfer agent costs. During the six months ended September 30, 2004, the amount of such expenses allocated to the fund was $278,047. The fund has entered into an arrangement with its custodian whereby credits realized as a result of directed brokerage commissions, were used to reduce a portion of the fund's expenses. During the six months ended September 30, 2004, the funds custodian fees were reduced by $137 under this arrangement. The fees of the Trustees not currently affiliated with the Adviser amounted to $21,381 during the six months ended September 30, 2004. The fund has agreed to pay the Adviser for certain administrative costs incurred in providing other assistance and services to the fund. The fee was based on a fixed amount that has been allocated equally among the State Street Research funds. During the six months ended September 30, 2004, the amount of such expenses was $57,442. Note 3 For the six months ended September 30, 2004, purchases and sales of securities, exclusive of short-term obligations, aggregated $607,745,049, and $576,514,625, respectively. Note 4 The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the plans, the fund pays annual service fees to the Distributor at a rate of 0.25% of average daily net assets for Class A, Class B(1), Class B and Class C shares. In addition, the fund pays annual distribution fees of 0.05% of average daily net assets for Class A shares and 0.75% of average daily net assets for Class B(1), Class B and Class C shares. Currently, the annual service and distribution fees paid by Class B shares have been voluntarily waived to 0.00%. The fund expects this waiver to continue, although there is no guarantee that it will. The Distributor uses such payments for personal services and/or the maintenance of shareholder accounts, to reimburse securities dealers for distribution and marketing services, to furnish ongoing assistance to investors and to defray a portion of its distribution and marketing expenses. For the six months ended September 30, 2004, fees pursuant to such plans amounted to $553,606, $679,300, and $240,986 for Class A, Class B(1) and Class C shares, respectively. For Class A, Class B and Class C shares, the payments are intended to reimburse the distributor for expenditures incurred under the plan, and any unused payments are returnable to the fund. During the six months ended September 30, 2004, the Distributor reimbursed a total of $294,508 to Class B shares of the fund reflecting the estimated excess of payments received over costs incurred under the plan. This amount is shown as "Reimbursement of distribution fees" in the Statement of Operations. For Class B(1), the payments compensate the distributor for services and expenditures incurred under the plan, and none of the payments are returnable to the fund. As of September 30, 2004, there were $3,625,865, $16,629 and $2,225,942 for Class A, Class B, and Class C shares, respectively, of unreimbursed distribution and shareholder servicing related expenses to be carried forward to future plan years. The fund has been informed that the Distributor and MetLife Securities, Inc., a wholly owned subsidiary of MetLife, earned initial sales charges aggregating $1,416,764 and $5,829,512, respectively, on sales of Class A shares of the fund during the six months ended September 30, 2004, and that MetLife Securities, Inc. earned commissions aggregating $6,003,620 and $133,336 on sales of Class B(1) and Class C shares, respectively, and the Distributor collected contingent deferred sales charges aggregating $202,535, $424 and $6,810 on redemptions of Class B(1), Class B and Class C shares, respectively, during the same period. Note 5 MetLife announced that it has entered into an agreement to sell the Adviser as part of a larger transaction to sell MetLife's asset management business to BlackRock, Inc. ("BlackRock"). The acquisition by BlackRock of MetLife's asset management business is expected to occur in the first quarter of 2005. At the time of the closing, the advisory agreement between the fund and the Adviser and the distribution agreement between the fund and the Distributor will be terminated. BlackRock Advisors, Inc. and BlackRock Distributors, Inc., wholly owned subsidiaries of BlackRock, will serve as investment adviser and distributor, respectively. A Special Meeting of Shareholders of the fund has been tentatively scheduled for December 2004. At this meeting, shareholders of the fund will be asked to consider and approve a plan of reorganization between the fund and the BlackRock Balanced Portfolio. If the proposed reorganization is approved by shareholders of the fund, the BlackRock Balanced Portfolio would acquire substantially all of the assets and liabilities of the fund. In exchange, shareholders of the fund would receive shares of the BlackRock Balanced Portfolio with an aggregate value equivalent to the aggregate net asset value of their fund shares at the time of the transaction. If the proposed reorganization is not approved by shareholders of the fund, the Board of Trustees will need to consider other alternatives relating to the management and operations of the fund, including without limitations, seeking an alternative investment adviser for the fund or seeking shareholder approval to liquidate the fund.* * The foregoing is not an offer to sell, nor a solicitation of an offer to buy, shares of any fund, nor is it a solicitation of any proxy. State Street Research Asset Allocation Fund 21 Note 6 The Trustees have the authority to issue an unlimited number of shares of beneficial interest at $0.001 par value per share.

Gross Domestic Product (GDP), a common measure of economic growth, rose at a pace of more than 3.5% for the first half of 2004. Estimates for second half suggest that the pace of growth could have picked up somewhat, as the US economy remains on solid ground. Consumer confidence wavered early in the period as the number of new jobs added to the economy fell below expectations. When the job picture brightened in April and May, consumer confidence tracked higher. More than 1.2 million jobs were added to the U.S. economy in the spring, and the quality of new jobs improved, as reported by the U.S. Labor Department. However, caution returned on disappointing jobs reports in July and August and consumer confidence pulled back. Yet, consumers continued to fuel the economy, pumping dollars into the retail and housing markets. Sales of new and existing homes soared as homebuyers anticipated higher mortgage rates ahead. Corporate profits continued to rise, making it easier for companies to increase spending, especially on information technology, electronic equipment and new jobs. As the period wore on, it became clear that the days of record-low short-term interest rates were coming to an end. In June, the Federal Reserve Board raised the federal funds rate from 1.0% to 1.25%. The Fed raised this key short-term rate to 1.5% in August and to 1.75% in September. These increases had little or no impact on the financial markets because they had been widely anticipated and because the Fed has signaled that it will take a measured approach to raising rates as the economic recovery matures. Stocks Stumble as Bonds Edge Higher After a relatively positive start to the calendar year, a host of worries stopped the major stock market indexes in their tracks. Investors grew more cautious about interest rates, rising energy prices, the threat of terrorist attacks and the outcome of the presidential election and stocks retreated. Value stocks held up considerably better than growth stocks. The energy sector was the stock market's strongest performer. High-yield bonds continued to lead the bond market. Most other sectors of the bond market eked out modest positive returns as the yield on the benchmark 10-year U.S. Treasury bond moved lower in the final months of the period. Yields and bond prices move in opposite directions. Looking Ahead Any time the financial markets deliver negative returns, it is disheartening for investors. However, the seeds of a new market rally are often sown in periods of weakness and decline. With a diversified portfolio and a long-term perspective on the markets, it is easier to weather periods of volatility--and more likely that you may reap the potential benefits in better times. We urge you to talk to your investment professional about your investment plan. And we look forward to helping you achieve your long-term financial goals. Sincerely, /s/ Richard S. Davis Richard S. Davis Chairman September 30, 2004 2 PERFORMANCE Discussion as of September 30, 2004 How State Street Research High Income Fund Performed State Street Research High Income Fund (Class A shares, without sales charge) returned 3.53% for the six-month period ended September 30, 2004. That was higher than its peer group, the Lipper High Current Yield Funds Average, which was 3.43% for the period. However, the fund underperformed the CSFB Global High Yield II Index, which returned 4.29% over the same period.

Current performance may be lower or higher than the performance data quoted herein. For the most recent month-end performance results, visit our website at www.ssrfunds.com. The fund's share price, yield and return will fluctuate, and you may have a gain or loss when you sell your shares. All returns assume reinvestment of capital gains distributions and income dividends at net asset value. The returns shown do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Average annual total return without sales charge does not reflect the maximum applicable sales charges. If the applicable sales charges were deducted, performance results would be lower. Average annual total return at maximum applicable sales charge reflects a maximum 4.5% Class A share front-end sales charge, or 5% Class B(1) or B share or 1% Class C share contingent deferred sales charge (CDSC) where applicable. Performance for Class B(1) shares reflects Class B share performance through December 31, 1998, and Class B(1) performance thereafter. If the returns for Class B(1) shares had reflected their current service/ distribution (Rule 12b-1) fees for the entire period, these returns would have been lower. Class S shares, offered without sales charge, are available through certain employee benefit plans and special programs. The Lipper High Current Yield Funds Average shows the performance of a category of mutual funds with similar goals. The Lipper average shows you how well the fund has done compared to competing funds. The CSFB Global High Yield II Index mirrors the public high-yield debt market, representing a total of 250 different sectors within this market. The index is unmanaged and does not take transaction charges into consideration. It is not possible to invest directly in an index. Reasons for the Fund's Performance Early in the period, the high-yield sector underperformed Treasuries as mixed economic news and increased geopolitical risk pressured the sector. However, high-yield performance picked up in the second half of the period as the economy put a "soft patch" behind it. High-yield led the fixed income markets for the six-month reporting period. The fund lost out on some performance because it had lower exposure to the lowest-quality CCC-rated issues than its benchmark. CCC-rated issues outperformed higher-rated, more stable issues during the period. However, this disappointment was somewhat offset by strong performance from B-rated securities, where the fund's exposure was higher than that of its benchmark. An emphasis on securities in the chemical industry helped the fund's return because chemical bonds were strong performers. Our decision to underweight the utilities sector was also rewarded as the sector lagged during the period. Looking Ahead We continue to believe that the high-yield sector has the potential to generate competitive returns relative to other fixed income alternatives. However, after more than a year of strong price appreciation, the high-yield bond sector appears to be at or near full value. In this environment, we believe that security selection and risk avoidance will be key factors in performance. A Word about Risk The major risks of investing in high-yield, high-risk debt securities-- often referred to as "junk bonds"--include the tendency for prices to fall when the economy is sluggish or overall corporate earnings are weak. High-yield, high-risk debt securities reflect a greater possibility that adverse changes in an issuer's business or financial condition, or in general economic conditions, may impair the issuer's ability to pay principal and interest on the securities. The value of any bonds held by the fund is likely to decline when interest rates rise; this risk is greater for bonds with longer maturities.

About Your Fund Expenses As a fund shareholder, you incur two types of costs: (1) Transaction costs, which include sales charges, and (2) ongoing expenses, which include management fees, service/distribution fees (12b-l) and "other" expenses. The examples below illustrate the ongoing cost in dollars of investing in the fund and allow you to compare these costs with the expenses of other funds. The examples are based on a $1,000 investment at the beginning of the period and held for the entire period from March 31, 2004 to September 30, 2004. Actual Fund Return is based on the fund's actual return and expenses. To estimate the ongoing expenses you paid during the entire period shown, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number shown for your fund under the column "Expenses Paid during the Period". Hypothetical 5% Return is based on the fund's actual expense ratio and an assumed rate of 5% per year before expenses. Please note that the return used is not the fund's actual return; therefore, this information may not be used to estimate your actual ending balance and expenses paid during the period. To compare your fund's ongoing expenses with those of other funds, simply compare this 5% hypothetical example with the 5% hypothetical examples shown in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect transactional expenses such as sales charges, which would result in higher total expenses. It should also be noted that, for certain funds, expenses have been subsidized or reduced through expense offset arrangements, which reduces costs for shareholders. Generally, the fund expects that the expense subsidy or expense offset arrangement will continue although there is no guarantee that it will. Please see the fund's prospectus for more information. 4 PORTFOLIO Holdings September 30, 2004 (unaudited) Principal Maturity Amount Date Value - ---------------------------------------------------------------------------------------------- Bonds 98.1% Aerospace/Defense 2.3% Availl Inc.

The Trust consists presently of two separate funds: State Street Research High Income Fund and State Street Research Asset Allocation Fund. The investment objective of the fund is to seek, primarily, high current income and, secondarily, capital appreciation, from investments in fixed income securities. Under normal circumstances, the fund invests at least 80% of its net assets in lower-quality securities, primarily "junk bonds". At the time of purchase, these securities are rated within or below the BB or Ba major rating categories (Standard & Poor's/Moody's), or are unrated but considered equivalent by the investment manager. The fund may not invest more than 20% of its total assets in securities rated in the CCC/Caa or lower rating categories or equivalent at the time of purchase. Fixed income securities include bonds and other debt-like instruments such as asset- or mortgage-backed securities, and preferred stocks. The fund offers five classes of shares. Class A shares are subject to an initial sales charge of up to 4.50% and pay annual service and distribution fees equal to 0.30% of average daily net assets. Class B(1) shares pay annual service and distribution fees equal to 1.00% of average daily net assets and automatically convert into Class A shares (which pay lower ongoing expenses) at the end of eight years. Class B(1) shares are subject to a contingent deferred sales charge on certain redemptions made within six years of purchase. Class B shares are offered only to current shareholders through reinvestment of dividends and distributions or through exchanges from existing Class B accounts of State Street Research funds . Currently, the annual service and distribution fees paid by Class B shares have been voluntarily reduced to 0.00%. Class B shares automatically convert into Class A shares at the end of eight years. Class B shares are subject to a contingent deferred sales charge on certain redemptions made within five years of purchase. Class C shares are subject to a contingent deferred sales charge of 1.00% on any shares redeemed within one year of purchase. Class C shares also pay annual service and distribution fees equal to 1.00% of average daily net assets. Class S shares are only offered through certain retirement accounts, advisory accounts of State Street Research & Management Company (the "Adviser"), an investment management subsidiary of MetLife, Inc. ("MetLife"), and special programs. No sales charge is imposed at the time of purchase or redemption of Class S shares. Class S shares do not pay any service or distribution fees. The fund's expenses are borne pro rata by each class, except that each class bears expenses, and has exclusive voting rights with respect to provisions of the plans of distribution, related specifically to that class. Income, expenses (other than service and distribution fees), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets. The Trustees declare separate dividends on each class of shares. The following significant accounting policies are consistently followed by the fund in preparing its financial statements, and such policies are in conformity with accounting principles generally accepted in the United States of America. A. Investment Valuation Values for listed equity securities reflect final sales on national securities exchanges quoted prior to the close of the New York Stock Exchange. Over-the-counter securities quoted on the National Association of Securities Dealers Automated Quotation ("Nasdaq") system are valued at closing prices supplied through such system. If not quoted on the Nasdaq system, such securities are valued at prices obtained from independent brokers. In the absence of recorded sales, valuations are at the mean of the closing bid and asked quotations. Fixed income securities are valued by a pricing service, which utilizes market transactions, quotations from dealers, and various relationships among securities in determining value. If not valued by a pricing service, such securities are valued at prices obtained from independent brokers. Short-term securities maturing within sixty days are valued at amortized cost. Other securities, if any, are valued at their fair value as determined in good faith under consistently applied procedures established by and under the supervision of the Trustees. In the event that the market quotations for a portfolio instrument are not deemed to be readily available, the Investment Adviser's Valuation Committee determines the fair 10 The notes are an integral part of the financial statements. value for such portfolio instrument. The fair value of any such portfolio instruments are determined based upon a consideration of all available facts and information. The fair valuation of a restricted portfolio instrument reflects the inherent worth of the portfolio instrument, without regard to the restrictive feature, adjusted for any diminution in value resulting from the restrictive feature. The Investment Adviser and the Custodian also monitor domestic and foreign markets and news information for any developing events that may have an impact on the valuation of portfolio instruments. Such monitoring includes general market news and financial market information sources currently utilized in making investment decisions, trading and investment personnel located abroad, foreign regional brokers, and/or foreign custodians. The value assigned to these securities is based upon available information at the time, and does not necessarily represent the amount which might ultimately be realized upon sale. B. Security Transactions Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains or losses are reported on the basis of identified cost of securities delivered. As part of the custodian contract between the custodian bank and the fund, the custodian bank has a lien on the securities of the fund to the extent permitted by the fund's investment restriction to cover any advances made by the custodian bank for the settlement of securities purchased by the fund. At September 30, 2004, the payable to the custodian bank of $228,163 represents the amount due for cash advance for the settlement of a security purchased. C. Net Investment Income Net investment income is determined daily and consists of interest and dividends accrued and discount earned, less the estimated daily expenses of the fund. Interest income is accrued daily as earned. Dividend income is accrued on the ex-dividend date. The fund is charged for expenses directly attributable to it, while indirect expenses are allocated between both funds in the Trust. D. Dividends Dividends from net investment income are declared daily and paid or reinvested monthly. Net realized capital gains, if any, are distributed annually, unless additional distributions are required for compliance with applicable tax regulations. Income dividends and capital gains distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. The difference is primarily caused by differing treatment of accrued interest on defaulted bonds and premium amortization on fixed income securities. E. Federal Income Taxes No provision for federal income taxes is necessary because the fund has elected to qualify under Subchapter M of the Internal Revenue Code and its policy is to distribute all of its taxable income, including net realized capital gains, within the prescribed time periods. At March 31, 2004, the fund had a net capital loss carryforward of $455,595,025 available, to the extent provided in regulations, to offset future capital gains, if any, of which $3,347,001, $43,790,700, $69,423,365, $274,585,781 and $64,448,178 expire on March 31, 2007, 2008, 2009, 2010 and 2011, respectively. A portion of the losses expiring in 2007, 2008, 2009 and 2010, $3,347,001, $5,252,309, $11,304,243 and $949,368, respectively, were acquired in connection with the merger of State Street Research Strategic Income Fund. Future utilization of these losses may be limited under current tax laws. F. Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from these estimates. G. Securities Lending The fund may seek additional income by lending portfolio securities to qualified institutions. The fund will receive cash or securities as collateral in an amount equal to at least 100% of the current market value of any loaned securities plus accrued interest. By reinvesting any cash collateral it receives in these transactions, the fund could realize additional gains and losses. If the borrower fails to return the securities and the value of the collateral has declined during the term of the loan, the fund will bear the loss. At September 30, 2004, the value of the securities loaned and the value of collateral were $33,960,405 and $34,638,408, respectively. During the six months ended September 30, 2004, income from securities lending amounted to $36,010 . H. Futures The fund may enter into futures contracts as a hedge against unfavorable market conditions and to enhance income. The fund will not purchase any futures contract if, after such purchase, more than one-third of net assets would be represented by long future contracts. The fund will limit its risks by entering into a futures position only if it appears to be a liquid investment. Upon entering into a futures contract, the fund deposits with the selling broker sufficient cash or U.S. government securities to meet the minimum "initial margin" requirements. Thereafter, the fund receives from or pays to the broker cash or U.S. government securities equal to the daily fluctuation in value of the contract ("variation margin"), which is recorded as 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 has opened and the value at the time it was closed. The potential risk to the fund is that the change in value of futures contracts may not correspond to the change in value of the hedged instruments. In addition, losses may arise in changes from 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. Note 2 The Trust and the Adviser have entered into an agreement under which the Adviser earns monthly fees at an annual rate of 0.60% of the first $500 million of net assets annually, 0.55% of the next $500 million, and 0.50% of any amount over $1 billion. In consideration of these fees, the Adviser furnishes the fund with management, investment advisory, statistical and research facilities and services. The Adviser also pays all salaries, rent and certain other expenses of management. During the six months ended September 30, 2004, the fees pursuant to such agreement amounted to $950,244. State Street Research Service Center, a division of State Street Research Investment Services, Inc., the Trust's principal underwriter (the "Distributor"), provides certain shareholder services to the fund such as responding to inquiries and instructions from investors with respect to the purchase and redemption of shares of the fund. In addition, MetLife receives a fee for maintenance of the accounts of certain shareholders who are participants in sponsored arrangements, such as employee benefit plans, through or under which shares of the fund may be purchased. Total shareholder service costs are allocated to each fund in the same ratios as the transfer agent costs. During the six months ended September 30, 2004, the amount of such expenses allocated to the fund was $135,981. The fees of the Trustees not currently affiliated with the Adviser amounted to $15,165 during the six months ended September 30, 2004. The fund has agreed to pay the Adviser for certain administrative costs incurred in providing other assistance and services to the fund. The fee was based on a fixed amount that has been allocated equally among State Street Research funds. During the six months ended September 30, 2004, the amount of such expenses was $46,299. Note 3 For the six months ended September 30, 2004, purchases and sales of securities, exclusive of short-term obligations and U.S. government obligations, aggregated $197,785,095 and $226,326,596, respectively. Note 4 The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the plans, the fund pays annual service fees to the Distributor at a rate of 0.25% of average daily net assets for Class A, Class B(1) and Class C shares. In addition, the fund pays annual distribution fees of 0.05% of average daily net assets for Class A shares. The fund pays annual distribution fees of 0.75% of average daily net assets for Class B(1) and Class C shares. Currently, the annual service and distribution fees paid by Class B shares have been voluntarily reduced to 0.00%. The fund expects this waiver to continue, although there is no guarantee that it will. The Distributor uses such payments for personal services State Street Research High Income Fund 11 and/or the maintenance of shareholder accounts, to reimburse securities dealers for distribution and marketing services, to furnish ongoing assistance to investors and to defray a portion of its distribution and marketing expenses. For the six months ended September 30, 2004, fees pursuant to such plans amounted to $330,428, $192,773 and $54,889 for Class A, Class B(1) and Class C shares, respectively. For Class A, Class B and Class C shares, the payments are intended to reimburse the distributor for expenditures incurred under the plan, and any unused payments are returnable to the fund. During the six months ended September 30, 2004, the Distributor reimbursed a total of $271,424 to Class B shares of the fund reflecting the estimated excess of payments received over costs incurred under the plan. This amount is shown as "Reimbursement of distribution fees" in the Statement of Operations. As of September 30, 2004, there were $3,102,114, $12,867 and $2,440,763 for Class A, Class B(1) and Class C, respectively, of unreimbursed distribution and shareholder servicing related expenses to be carried forward to future plan years. For Class B(1) shares, the payments compensate the distributor for services and expenditures incurred under the plan, and none of the payments are returnable to the fund. The fund has been informed that the Distributor and MetLife Securities, Inc., a wholly owned subsidiary of MetLife, earned initial sales charges aggregating $270,005 and $1,653,913, respectively, on sales of Class A shares of the fund during the period ended September 30, 2004, and that MetLife Securities, Inc., earned commissions aggregating $922,534 and $69,488 on sales of Class B(1) and Class C shares, respectively, and the Distributor collected contingent deferred sales charges aggregating $75,332, $166 and $2,628 on redemptions of Class B(1), Class B and Class C shares, respectively, during the same period. Note 5 MetLife announced that it has entered into an agreement to sell the Adviser as part of a larger transaction to sell MetLife's asset management business to BlackRock, Inc. ("BlackRock"). The acquisition by BlackRock of MetLife's asset management business is expected to occur in the first quarter of 2005. At the time of the closing, the advisory agreement between the fund and the Adviser and the distribution agreement between the fund and the Distributor will be terminated. BlackRock Advisors, Inc. and BlackRock Distributors, Inc., wholly owned subsidiaries of BlackRock, will serve as investment adviser and distributor, respectively. A Special Meeting of Shareholders of the fund has been tentatively scheduled for December 2004. At this meeting, shareholders of the fund will be asked to consider and approve a plan of reorganization between the fund and the BlackRock High Yield Bond Portfolio. If the proposed reorganization is approved by shareholders of the fund, the BlackRock High Yield Bond Portfolio would acquire substantially all of the assets and liabilities of the fund. In exchange, shareholders of the fund would receive shares of the BlackRock High Yield Bond Portfolio with an aggregate value equivalent to the aggregate net asset value of their fund shares at the time of the transaction. If the proposed reorganization is not approved by shareholders of the fund, the Board of Trustees will need to consider other alternatives relating to the management and operations of the fund, including without limitations, seeking an alternative investment adviser for the fund or seeking shareholder approval to liquidate the fund.* *The foregoing is not an offer to sell, nor a solicitation of an offer to buy, shares of any fund, nor is it a solicitation of any proxy. 12 Note 6 The trustees have the authority to issue an unlimited number of shares of beneficial interest at $0.001 par value per share.
