ITEM 1: REPORT TO SHAREHOLDERS The Semi-annual Report is attached. [LOGO] STATE STREET RESEARCH {GRAPHIC] Large-Cap Analyst Fund October 31, 2004 Semiannual Report to Shareholders Table of Contents 3 Performance Discussion 4 About Your Fund Expenses 5 Portfolio Holdings 7 Financial Statements 11 Financial Highlights 13 Trustees and Officers FROM THE CHAIRMAN State Street Research The U.S. economy grew at a solid pace during the six-month period ended October 31, 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. Preliminary estimates for the second half of the year suggest that the pace of growth remained 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 one 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 and continued to decline through the end of the period. 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. However, business spending fell short of expectations, given the maturation of the economic cycle. 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 subsequently raised this key short-term interest rate to 1.5% in August and then 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 until the last months of the reporting period. Value stocks held up considerably better than growth stocks, although growth turned the corner near the end of the period. 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 solid 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 substandard returns, it is disheartening for investors. However, the seeds of a new market rally are often sown in periods of weakness. 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 October 31, 2004 2 - ------------------------ PERFORMANCE - ------------------------ Discussion as of October 31, 2004 How State Street Research Large-Cap Analyst Fund Performed State Street Research Large-Cap Analyst Fund (Class A shares, without sales charge) returned 2.96% for the six-month period ended October 31, 2004. That was slightly less than the return of the Russell 1000[RegTM] Index, which was 3.04% over the same period. However, the fund outperformed the Lipper Large-Cap Core Funds Average, which returned 1.21% for the period. - ------------------------------------------------------------------------------- Performance - ------------------------------------------------------------------------------- Fund average annual total return as of 10/31/04 (does not reflect sales charge) Life of Fund 1 Year 5 Years (3/11/98) Class A 9.82% -0.32% 3.29% - ------------------------------------------------------------ Class B(1) 9.13% -1.05% 2.53% - ------------------------------------------------------------ Class B (closed) 11.86% -0.33% 3.09% - ------------------------------------------------------------ Class C 9.11% -1.03% 2.55% - ------------------------------------------------------------ Class S 10.23% -0.08% 3.54% - ------------------------------------------------------------ Fund average annual total return as of 9/30/04 (at maximum applicable sales charge) Life of Fund 1 Year 5 Years (3/11/98) Class A 8.07% -0.01% 2.22% - ------------------------------------------------------------ Class B(1) 8.90% 0.08% 2.38% - ------------------------------------------------------------ Class B (closed) 11.74% 0.78% 2.94% - ------------------------------------------------------------ Class C 12.87% 0.47% 2.41% - ------------------------------------------------------------ Class S 15.16% 1.44% 3.40% - ------------------------------------------------------------ Keep in mind that the performance data quoted represents past performance and is no guarantee of future results. 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(1) or B 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. Performance results for the fund are increased by the voluntary reduction of fund fees and expenses; without subsidization, performance would have been lower. The Russell 1000 Index measures the performance of the 1,000 largest securities in the Russell 3000[RegTM] Index (an unmanaged index of the 3,000 largest publicly traded U.S. companies). The index is unmanaged and does not take transaction charges into consideration. It is not possible to invest directly in an index. The Lipper Large-Cap Core 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. - -------------------------------------------------------------------------------- Reasons for the Fund's Performance In choppy market conditions, the Large-Cap Analyst portfolio performed in line with the Russell 1000 Index. Good stock selection in the health care, energy and consumer staples sectors drove returns over the period. Additionally, our bottom-up process led to an above-benchmark position in the best-performing energy sector, helping to compensate for select disappointments in producer durables and financial services. Oil prices approached $50/bbl during the period, bolstering the returns of energy-related securities. As a result, the integrated oils and other energy sectors were the top-performing sectors within both the index and the portfolio. In this environment, the portfolio's investments in coal- and oil-producing stocks delivered solid returns. The fund's positioning amid health care names also benefited returns during the period. Our pharmaceutical holdings tended to outperform their benchmark counterparts as the fund was able to avoid some of the weakest names. Specifically, our decision to underweight Merck helped returns as shares of the drugmaker hit an eight-year low after the company announced the withdrawal of its arthritis drug and painkiller, Vioxx. Stock selection within both the financial services and producer durables sectors hurt fund performance as positions in names such as multi-line insurer American International Group and power supply device maker American Power Conversion suffered during the period. Our lack of exposure to real estate investment trusts (REITs) in the financial services sector also had a negative impact on the fund's performance. Looking Ahead The portfolio's sector weights are maintained within stated limits around the benchmark's sector weights. Investment decisions are made primarily at the individual security and industry levels. While the market environment of the last several months has been erratic, trading more on "macro" than company-specific fundamentals, the portfolio has been well positioned to outperform its benchmark regardless of market direction. A Word about Risk The major risks of stock investing include sudden and unpredictable drops in value and period of lackluster performance. The fund invests in larger, more established companies, which may be unable to respond quickly to new competitive challenges such as changes in technology and consumer trends. Many larger companies also cannot sustain the higher growth rates of successful smaller companies during periods of extended economic expansion. The fund may underperform other stock funds during periods when large-company stocks in general are out of favor. The fund's policy of remaining invested in all sectors of the Russell 1000 Index means that its performance may be affected by sector-wide downturns. - -------------------------------------------------------------------------------- Summary Portfolio Schedule - -------------------------------------------------------------------------------- Industries % of Fund Net Assets Financial Services 21.8% - -------------------------------------------------------------------------------- Consumer Discretionary 15.7% - -------------------------------------------------------------------------------- Technology 14.3% - -------------------------------------------------------------------------------- Health Care 12.3% - -------------------------------------------------------------------------------- Utilities 8.1% - -------------------------------------------------------------------------------- Other 6.5% - -------------------------------------------------------------------------------- Consumer Staples 6.4% - -------------------------------------------------------------------------------- Materials & Processing 4.6% - -------------------------------------------------------------------------------- Integrated Oils 4.1% - -------------------------------------------------------------------------------- Other Energy 4.1% - -------------------------------------------------------------------------------- Producer Durables 1.5% - -------------------------------------------------------------------------------- Automobiles & Transportation 0.6% - -------------------------------------------------------------------------------- Total 100.0% - -------------------------------------------------------------------------------- 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. State Street Research Large-Cap Analyst Fund 3 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 April 30, 2004, to October 31, 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. - -------------------------------------------------------------------------------- Beginning Ending Expenses Account Account Paid Annualized Six months ended Value Value during Expense 10/31/04 4/30/04 10/31/04 Period* Ratio - -------------------------------------------------------------------------------- Actual Fund Return - -------------------------------------------------------------------------------- Class A $1,000 $ 1,023.05 $ 6.57 1.30% - -------------------------------------------------------------------------------- Class B(1) $1,000 $ 1,015.95 $10.08 2.00% - -------------------------------------------------------------------------------- Class B (closed) $1,000 $ 1,027.75 $ 5.27 1.04% - -------------------------------------------------------------------------------- Class C $1,000 $ 1,015.90 $10.08 2.00% - -------------------------------------------------------------------------------- Class S $1,000 $ 1,026.04 $ 5.07 1.00% - -------------------------------------------------------------------------------- Hypothetical 5% Return - -------------------------------------------------------------------------------- Class A $1,000 $ 1,018.50 $ 6.56 1.30% - -------------------------------------------------------------------------------- Class B(1) $1,000 $ 1,015.00 $10.08 2.00% - -------------------------------------------------------------------------------- Class B (closed) $1,000 $ 1,019.80 $ 5.25 1.04% - -------------------------------------------------------------------------------- Class C $1,000 $ 1,015.00 $10.08 2.00% - -------------------------------------------------------------------------------- Class S $1,000 $ 1,020.00 $ 5.05 1.00% - -------------------------------------------------------------------------------- * Expenses are equal to the fund's annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the period and then divided by the number of days in the year. - -------------------------------------------------------------------------------- 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 October 31, 2004 (unaudited) Issuer Shares Value - -------------------------------------------------------------------------------- Common Stocks 100.0% Automobiles & Transportation 0.6% Railroads 0.6% Union Pacific Corp.* ..................... 5,100 $ 321,147 ----------- Total Automobiles & Transportation .......................... 321,147 ----------- Consumer Discretionary 15.7% Casinos/Gambling, Hotel/Motel 0.8% International Game Technology Inc. ....... 12,800 422,912 ----------- Commercial Services 1.4% Cendant Corp. ............................ 12,600 259,434 InterActiveCorp.* ........................ 23,000 497,260 ----------- 756,694 ----------- Communications, Media & Entertainment 0.5% Univision Communications Inc.

The Trust presently consists of two separate funds: State Street Research Large-Cap Analyst Fund and State Street Research Legacy Fund. The fund seeks to provide long-term growth of capital. In seeking to achieve its investment objective, the fund invests at least 80% of net asset in large-cap stocks and convertible securities of U.S. and foreign companies. The fund considers large-cap companies to be those with market capitalizations within the range of the Russell 1000 Index (an index of the 1,000 largest publicly traded U.S. companies) and of other U.S. and foreign companies of comparable size. 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. For the period May 1, 2004 through September 30, 2004, the annual service and distribution fees paid by Class B shares had been voluntarily reduced to 0.00%. For the period from October 1, 2004, through October 31, 2004, the service and distribution fees paid by Class B shares are 0.25%. 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 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. 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 Adviser's Valuation Committee determines the fair value for such portfolio instrument. The fair 8 The notes are an integral part of the financial statements. Notes (continued) - -------------------------------------------------------------------------------- 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 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 October 31, 2004, the payable to the custodian bank of $111,620 represents the amount due for cash advance for the settlement of securities 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 to both funds in the Trust. D. Dividends Dividends from net investment income are declared and paid or reinvested annually. 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. 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 April 30, 2004, the fund had a capital loss carryforward of $7,516,820 available, to the extent provided in regulations, to offset future capital gains, if any, which expires on April 30, 2011. 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 October 31, 2004, the value of the securities loaned and the value of collateral were $1,086,874 and $1,125,298 (consisting entirely of cash collateral invested in State Street Navigator Securities Lending Prime Portfolio), respectively. The collateral was marked to market the next business day and made equal to at least 100% of the current market value of the loaned securities and accrued interest. During the six months ended October 31, 2004, income from securities lending amounted to $2,238. Note 2 The Trust and the Adviser have entered into an agreement under which the Adviser earns monthly fees at an annual rate of 0.65% of fund net assets. 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 October 31, 2004, the fees pursuant to such agreement amounted to $170,028. 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 October 31, 2004, the amount of such expenses allocated to the fund was $26,999. The fees of the Trustees not currently affiliated with the Adviser amounted to $10,362 during the six months ended October 31, 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 October 31, 2004, the amount of such expenses was $54,770. Note 3 The Distributor and its affiliates may from time to time and in varying amounts voluntarily assume some portion of fees and expenses relating to the fund. For the six months ended October 31, 2004, the amount of such expenses assumed by the Distributor and its affiliates was $209,139. Note 4 For the six months ended October 31, 2004, purchases and sales of securities, exclusive of short-term obligations, aggregated $24,585,148, and $25,016,882, respectively. Note 5 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. The fund pays annual distribution fees of 0.75% of average daily net assets for Class B(1), Class B and Class C shares. For the period May 1, 2004 through September 30, 2004, the annual service and distribution fees paid by Class B shares had been voluntarily reduced to 0.00%. For the period from October 1, 2004, through October 31, 2004, the service and distribution fees paid by Class B shares are 0.25%. 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 October 31, 2004, fees pursuant to such plans amounted to $50,299, $38,123, $1,668 and $5,350 for Class A, Class B(1), Class B 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. As of October 31, 2004, there were $705,597, $86,797 and $438,681 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. 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. During the six months ended State Street Research Large-Cap Analyst Fund 9 October 31, 2004, the Distributor reimbursed a total of $9,197 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. The fund has been informed that the Distributor and MetLife Securities, Inc., a wholly owned subsidiary of MetLife, earned initial sales charges aggregating $18,218 and $77,052, respectively, on sales of Class A shares of the fund during the six months ended October 31, 2004, and that MetLife Securities, Inc. earned commissions aggregating $56,683 and $762 on sales of Class B(1) and Class C shares, respectively, and the Distributor collected contingent deferred sales charges aggregating $8,702, $1,198 and $188 on redemptions of Class B(1), Class B and Class C shares, respectively, during the same period. Note 6 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 27, 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 Select Equity Portfolio. If the proposed reorganization is approved by shareholders of the fund, the BlackRock Select Equity 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 Select Equity 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. Note 7 The Trustees have the authority to issue an unlimited number of shares of beneficial interest at $0.001 par value per share.
