[LOGO] STATE STREET RESEARCH Innovative Ideas, Disciplined Investing.(TM) [graphic omitted] Investment Trust December 31, 2004 Annual Report to Shareholders - ------------------- PERFORMANCE - ------------------- Discussion as of December 31, 2004 How State Street Research Investment Trust Performed State Street Research Investment Trust (Class A shares, without sales charge) returned 10.35% for the 12-month period ended December 31, 2004. That was slightly less than the S&P 500 Index's return of 10.88% for the same period. However, the fund outperformed the Lipper Large-Cap Core Funds Average, which was 7.79% for the period. ================================================================================ Performance: Class A - -------------------------------------------------------------------------------- Fund average annual total return as of 12/31/04 (does not reflect sales charge) 1 Year 5 Years 10 Years 10.35% -4.33% 9.89% - -------------------------------------------------------------------------------- Fund average annual total return as of 12/31/04 (at maximum applicable sales charge) 1 Year 5 Years 10 Years 4.01% -5.45% 9.24% - -------------------------------------------------------------------------------- S&P 500 Index as of 12/31/04 1 Year 5 Years 10 Years 10.88% -2.30% 12.07% - -------------------------------------------------------------------------------- See pages 3 and 4 for additional performance data for Class A shares and for performance data on other share classes. 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, please call 1-877-773-8637. 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. 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 index 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 Concerns over the presidential election, interest rates and terrorism weighed on the markets during the first ten months of the year. However, investors shook off their concerns once the presidential election was resolved, and stocks rallied strongly in the fourth quarter. In this environment, health care, financial services and energy selections benefited performance, as did an overweight in energy stocks. The fund's exposure to integrated oils and utility stocks was lower than that of its benchmark, and this detracted from its return. However, in general, the fund's energy holdings, such as EOG Resources, benefited from elevated commodity prices. Heightened inventories and waning semiconductor demand proved costly in the producer durables and technology sectors. A Word about Risk The major risks of stock investing include sudden and unpredictable drops in value and periods 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 growth and income stocks are out of favor. ================================================================================ Summary Portfolio Schedule - ------------------------------------------------------------------------------- Industries % of Fund Net Assets Financial Services 16.9% - ------------------------------------------------------------------------------- Consumer Discretionary 16.6% - ------------------------------------------------------------------------------- Technology 14.9% - ------------------------------------------------------------------------------- Health Care 12.7% - ------------------------------------------------------------------------------- Other 8.2% - ------------------------------------------------------------------------------- Consumer Staples 7.6% - ------------------------------------------------------------------------------- Utilities 7.2% - ------------------------------------------------------------------------------- Materials & Processing 7.1% - ------------------------------------------------------------------------------- Other Energy 4.7% - ------------------------------------------------------------------------------- Integrated Oils 2.1% - ------------------------------------------------------------------------------- Producer Durables 0.6% - ------------------------------------------------------------------------------- Net Cash 1.4% - ------------------------------------------------------------------------------- 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. 2 - ----------------- PERFORMANCE - ----------------- Discussion as of December 31, 2004 These two pages focus on the fund's long-term track record. While a mutual fund's past performance is not a guarantee of future results, long-term returns can serve as an important context for evaluating recent performance. There are three ways of measuring long-term performance: cumulative total returns, average annual total returns and the change in dollar value over time of a given investment. Information about these measures follows, while the share class boxes contain the results of these measures for each share class. Cumulative Total Return Represents the total percentage you would have earned or lost if you had invested a lump sum in the fund and left it there until the end of the period indicated. Average Annual Total Return Represents the rate you would have had to earn during each year of a given time period in order to end up with the fund's actual cumulative return for those years. In reality, of course, fund performance varies from year to year. Because of this, a fund's actual performance for a given year may be higher or lower than an average annual performance figure. $10,000 Over Ten Years Similar to cumulative total return, but uses dollars rather than percentages, and assumes that the lump sum you invested was $10,000 (less the applicable maximum sales charge, if any) and compares fund performance to the performance of a market index. ================================================================================ Class A Life of Fund 1 Year 5 Years 10 Years (7/29/24) - ------------------------------------------------------------------------------ Cumulative Total Return (does not reflect sales charge) 10.35% -19.85% 156.87% 1,086,424.79% - ------------------------------------------------------------------------------ Cumulative Total Return (at maximum applicable sales charge) 4.01% -24.46% 142.10% 1,022,625.75% - ------------------------------------------------------------------------------ Average Annual Total Return (at maximum applicable sales charge) 4.01% -5.45% 9.24% 12.16% - ------------------------------------------------------------------------------ [THE FOLLOWING WAS REPRESENTED AS A MOUNTAIN CHART IN THE PRINTED MATERIAL] $10,000 Over 10 Years (reflects maximum applicable sales charge) S&P 500 Class A Index ------- ------- $10,000 $10,000 '95 13,285 13,757 '96 16,078 16,916 '97 20,726 22,562 '98 26,761 29,010 '99 32,047 35,115 '99 30,157 31,924 '01 24,595 28,130 '02 17,927 21,916 '03 23,277 28,204 '04 25,687 31,268 ================================================================================ ================================================================================ Class B(1) Life of Fund 1 Year 5 Years 10 Years (7/29/24) - ------------------------------------------------------------------------------ Cumulative Total Return (does not reflect sales charge) 9.59% -22.65% 138.89% 999,174.92% - ------------------------------------------------------------------------------ Cumulative Total Return (at maximum applicable sales charge) 4.59% -24.04% 138.89% 997,882.25% - ------------------------------------------------------------------------------ Average Annual Total Return (at maximum applicable sales charge) 4.59% -5.35% 9.10% 12.12% - ------------------------------------------------------------------------------ [THE FOLLOWING WAS REPRESENTED AS A MOUNTAIN CHART IN THE PRINTED MATERIAL] $10,000 Over 10 Years (reflects maximum applicable sales charge) S&P 500 Class B(1) Index ---------- ------- $10,000 $10,000 '95 13,186 13,757 '96 15,844 16,916 '97 20,249 22,562 '98 25,971 29,010 '99 30,883 35,115 '00 28,849 31,924 '01 23,391 28,130 '02 16,896 21,916 '03 21,798 28,204 '04 23,889 31,268 ================================================================================ Keep in mind that the performance data quoted represents past performance and is no guarantee of future results.

The fund's share price, yield and return will fluctuate, and you may have a gain or a 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. Performance includes periods prior to the creation of share classes, which resulted in new 12b-1 fees and which will reduce subsequent performance. During the periods prior to 1990 when shares of the fund were not offered to the general public, the fund was not subject to the cash inflows and higher redemptions and expenses that have occurred during the fund's current continuous public offering. Cumulative 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.

Performance for Class B(1) shares reflects Class B share performance through December 31, 1998, and Class B(1) performance thereafter. If the returns of Class B(1) shares had reflected their current service/ distribution on (Rule 12b-1) fees for the entire period, returns would have been lower. Class S shares, offered without sales charge, are available through certain retirement plans and special programs. 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 index is unmanaged and does not take transaction charges into consideration. It is not possible to invest directly in the index. 4 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 June 30, 2004, to December 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 12/31/04 6/30/04 12/31/04 Period* Ratio - ------------------------------------------------------------------------------------ Actual Fund Return - ------------------------------------------------------------------------------------ Class A $1,000 $1,073.23 $5.81 1.12% - ------------------------------------------------------------------------------------ Class B(1) $1,000 $1,069.04 $9.41 1.82% - ------------------------------------------------------------------------------------ Class B $1,000 $1,075.84 $4.26 0.82% - ------------------------------------------------------------------------------------ Class C $1,000 $1,069.92 $9.42 1.82% - ------------------------------------------------------------------------------------ Class S $1,000 $1,074.19 $4.25 0.82% - ------------------------------------------------------------------------------------ Hypothetical 5% Return - ------------------------------------------------------------------------------------ Class A $1,000 $1,019.40 $5.65 1.12% - ------------------------------------------------------------------------------------ Class B(1) $1,000 $1,015.90 $9.17 1.82% - ------------------------------------------------------------------------------------ Class B $1,000 $1,020.90 $4.14 0.82% - ------------------------------------------------------------------------------------ Class C $1,000 $1,015.90 $9.17 1.82% - ------------------------------------------------------------------------------------ Class S $1,000 $1,020.90 $4.14 0.82% * 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.

The investment objective of the fund is long-term growth of capital and, secondarily, long-term growth of income. Under normal market conditions, the fund invests at least 65% of its net assets in stocks and convertible securities that have long-term growth potential. In seeking to achieve its investment objective, the fund generally attempts to identify the industries that over the long term will grow faster than the economy as a whole. 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% 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. For the period January 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 December 31, 2004, the annual 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% 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 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 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 The notes are an integral part of the financial statements. State Street Research Investment Trust 9 Notes (continued) - -------------------------------------------------------------------------------- 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 December 31, 2004, the payable to the custodian bank of $249,918 represents the amount due for cash advances 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. D. Dividends Dividends from net investment income are normally 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. The fund has designated $11,041,266 as ordinary income dividends and $0 as long-term capital gains distributions. 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 December 31, 2004, the fund had a capital loss carryforward of $310,580,746 available, to the extent provided in regulations, to offset future capital gains, if any, which expires on December 31, 2010. To the extent book/tax differences are permanent in nature, such amounts are reclassified within the capital accounts based on federal tax basis treatment. The fund reclassified for book purposes amounts arising from permanent book/tax differences primarily relating to dispositions of securities that have different bases for financial reporting and tax purposes. At December 31, 2004, the components of distributable earnings on a tax basis differ from the amounts reflected in the Statement of Assets and Liabilities by temporary book/tax differences largely arising from wash sales, and capital loss carryforwards. At December 31, 2004, the tax basis distributable earnings were $655,370 in undistributed ordinary income, $0 in undistributed short-term capital gains and $0 in undistributed long-term gains. 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 December 31, 2004, the value of the securities loaned and the value of collateral were $52,028,600 and $53,465,159 (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 year ended December 31, 2004, income from securities lending amounted to $108,528. Note 2 The Trust and the Adviser have entered into an agreement under which the Adviser earns monthly fees at an annual rate of 0.55% of the first $500 million of net assets annually, 0.50% of the next $500 million, and 0.45% 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 year ended December 31, 2004, the fees pursuant to such agreement amounted to $7,270,745. 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 year ended December 31, 2004, the amount of such expenses allocated to the fund was $1,072,422. 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 year ended December 31, 2004, the fund's custodian fees were reduced by $115,878 under this arrangement. The fees of the Trustees not currently affiliated with the Adviser amounted to $61,721 during the year ended December 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 year ended December 31, 2004, the amount of such expenses was $110,725. During the year ended December 31, 2004, the Adviser conducted an internal review regarding the use of fund brokerage commissions in consideration of the distribution of shares. In connection with this review, the Adviser determined to reimburse the fund the entire amount of any such identified brokerage commissions, and reviewed this matter with the Trustees of the fund. The reimbursement was allocated among the fund's shares classes as follows: $338,360 to Class A; $198,252 to Class B(1); $137,911 to Class B; $19,934 to Class C; and $420,569 to Class S. These amounts are shown in the total amount of $1,115,026 as "Net increase from payment by affiliate" on the Statement of Operations. On February 19, 2004, the Distributor entered into an agreement with the NASD resolving all outstanding issues relating to an investigation by the NASD of the Distributor's email retention practices and supervision of trading activity in shares of the State Street Research funds. The Distributor, without admitting or denying the allegations or the findings set forth in the agreement, and solely for the purposes of the settlement, agreed to the entry of certain findings by the NASD relating to the Distributor's compliance with document retention requirements and the Distributor's supervision of enforcement of shareholder exchange limitations set forth in the funds' prospectuses. The agreement contains no allegations or findings of fraudulent conduct by the Distributor. As part of this agreement the Distributor made a payment to the fund to compensate the fund for losses relating to the exchange of fund shares beyond the annual limit set forth in the fund's prospectus. The payment was allocated among the fund's share classes as follows: $3,110 to Class A; $1,922 to Class B(1); $1,632 to Class B; $214 to Class C and $3,936 to Class S. These amounts are shown in the total amount of $10,814 as "Net increase from payment by affiliate" in the Statement of Operations. Note 3 For the year ended December 31, 2004, purchases and sales of securities, exclusive of short-term obligations, aggregated $1,212,751,979, and $1,459,666,224, respectively. 10 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 . 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 January 1, 2004 through September 30, 2004, the annual service and distribution fees paid by the Class B shares had been voluntarily reduced to 0.00%. For the period from October 1, 2004, through December 31, 2004, the annual service and distribution fees paid by Class B shares was 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 year ended December 31, 2004, fees pursuant to such plans amounted to $1,276,280, $2,580,539 and $277,310 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. As of December 31, 2004, there were $7,587,442, $61,730 and $2,773,860 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 year ended December 31, 2004, the Distributor reimbursed a total of $383,809 to Class B shares of the fund reflecting the estimated excess of payments received over costs incurred under the plan. The gross reimbursement amount of $383,809 was netted with the Class B distribution fee of $112,112. The net amount of $271,697 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 $286,209 and $1,563,803, respectively, on sales of Class A shares of the fund during the year ended December 31, 2004, and that MetLife Securities, Inc. earned commissions aggregating $1,958,935 and $12,787 on sales of Class B(1) and Class C shares, respectively, and the Distributor collected contingent deferred sales charges aggregating $719,979, $1,355 and $629 on redemptions of Class B(1), Class B and Class C shares, respectively, during the same period.

State Street Research Investment Trust 13 - --------- REPORT OF - --------- Independent Registered Public Accounting Firm To the Board of Trustees and Shareholders of State Street Research Investment Trust: We have audited the accompanying statement of assets and liabilities, including the portfolio holdings, of State Street Research Investment Trust (the "Fund"), a series of State Street Research Master Investment Trust, as of December 31, 2004, and the related statement of operations for the year then ended, and the statement of changes in net assets, and the financial highlights for each of the two years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for each of the years in the three-year period ended December 31, 2002, were audited by other auditors whose report dated February 12, 2003, expressed an unqualified opinion on such financial highlights. We conducted our audits in accordance with 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 and financial highlights are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also 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, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2004, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the Fund as of December 31, 2004, the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.
