REPORTS TO STOCKHOLDERS. (MAINSTAY LOGO) MAINSTAY CAPITAL APPRECIATION FUND The MainStay Funds Annual Report October 31, 2005 This page intentionally left blank 2 MainStay Capital Appreciation Fund MESSAGE FROM THE PRESIDENT During the 12 months ended October 31, 2005, most domestic and international stock markets provided positive overall returns. In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /S/ CHRISTOPHER O. BLUNT Christopher O.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000 $1,107.85 $ 6.75 $1,018.65 $ 6.46 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000 $1,104.50 $10.72 $1,014.90 $10.26 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000 $1,104.50 $10.72 $1,014.90 $10.26 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000 $1,107.80 $ 5.53 $1,019.80 $ 5.29 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests in securities of U.S. companies with characteristics such as participation in expanding product or service markets, increasing unit sales volume, increasing return on investment, and better-than-average growth in revenues and earnings when compared to stocks of the S&P 500(R) Index.(1) In implementing this strategy, the Fund maintains a flexible approach and may invest in various types of companies and securities. We look for companies that we feel are ready for a rise in price or may experience acceleration in growth of earnings, possibly as a result of changes in management, products, consumer demand, or the economy. We may sell a security if we no longer believe it will contribute to meeting the Fund's investment objective. WHAT KEY FACTORS INFLUENCED THE EQUITY MARKET DURING THE REPORTING PERIOD? Arguably the biggest factor influencing the equity market during the reporting period was the rise in the price of crude oil, which came on the heels of a 78% increase in crude-oil prices in the previous year. The price of crude oil rose as high as $69.81 per barrel on August 30, 2005, before falling off somewhat. This energy inflation was among the factors that prompted the Federal Open Market Committee to raise the federal funds target rate at a "measured pace" throughout the reporting period. To keep inflation in check, the FOMC raised the federal funds target rate eight times during the reporting period, with a 25-basis-point increase on each occasion. (A basis point is one-hundredth of a percentage point.) Since high energy prices act as a silent tax on consumers and can weigh on consumer spending, energy costs were a continuing concern for equity investors. On the geopolitical front, negative headlines about progress in Iraq also weighed heavily on investors' minds throughout the reporting period. WHAT DECISIONS HAD THE BIGGEST INFLUENCE ON THE FUND'S PERFORMANCE? Excluding all sales charges, all of the Fund's share classes outperformed the Fund's primary benchmark, the Russell 1000(R) Growth Index,(2) for the 12 months ended October 31, 2005. Effective stock selection in the health care sector had the most dramatic positive impact on the Fund's relative performance during the reporting period. The Fund's relative results were also helped by overweighted positions in energy and consumer discretionary stocks. Energy stocks benefited from a dramatic rise in the price of oil. Consumer discretionary stocks showed solid performance, with historically low interest rates and a strong housing environment that strengthened consumer spending. An underweighted position in consumer staples and effective stock selection in the sector also helped relative returns as did a modestly overweighted position in materials and strong stock selection in the sector. The Fund's underweighted allocation to financials had a neutral impact on relative results. An overweighted position and poor stock selection in industrials had a negative impact on the Fund's performance. We reduced the Fund's industrial holdings to a market-weighted position as the year progressed. Although the Fund was prudently underweighted in information technology through much of 12-month reporting period, stock selection in the sector hurt the Fund's relative performance. WHICH INDIVIDUAL SECURITIES HAD THE GREATEST POSITIVE IMPACT ON PERFORMANCE DURING THE REPORTING PERIOD? Peabody Energy mines and sells low-sulphur coal, mostly to utilities. With the dramatic rise in the price of oil, investors surmised that demand for alternative energy sources, such as coal, nuclear energy, and natural gas, would also increase. Apple Computer, a leading manufacturer of personal computers and consumer electronics, advanced primarily on the sales strength of its popular iPod MP-3 players. Caremark Rx is a pharmacy benefit management company. During the reporting period, the company integrated a major acquisition, signed several new contracts, expanded operating margins, and rapidly increased earnings. Health care provider UnitedHealth Group enjoyed strong earnings because of robust demand and strong pricing power in the health care services sector. Shares of Genentech, a biotechnology company, advanced on strong earnings growth, promising new products, and positive results in clinical trials. WHICH STOCKS DETRACTED FROM PERFORMANCE? Maxim Integrated Products, a manufacturer of linear and mixed-signal integrated circuits, saw its stock price decline primarily because of a cautious earnings outlook, heightened competition, and a shift to relatively lower-margin consumer products. The world's largest on-line auction site, eBay, felt the effects of slowing economic growth in Western European markets and softening transaction volume in the United States. Brunswick is a manufacturer of 1. See footnote on page 5 for more information on the S&P 500(R) Index. 2. See footnote on page 5 for more information on the Russell 1000(R) Growth Index. 8 MainStay Capital Appreciation Fund recreational products, including boats, marine engines, and equipment for fitness, bowling, and billiards. During the reporting period, Brunswick lowered its 2005 earnings guidance and cut production in the face of rising interest rates, higher oil prices, devastating hurricanes, and declining consumer confidence. Harman International Industries is a supplier of high-fidelity audio products and electronics systems for the consumer and professional markets. The company provided disappointing earnings guidance for fiscal 2006 and faced heightened competition in the low-end navigation-systems market. Motorcycle manufacturer Harley-Davidson lowered production guidance for the first time in the company's history. Sales, earnings, and profit projections were also adjusted, which took a toll on the company's shares. WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? In the spring of 2005, we sold the Fund's entire positions in several technology stocks because our research suggested that the companies' revenue and earnings growth might slow. The companies were Applied Materials, the industry's largest semiconductor equipment company; KLA Tencor, a manufacturer of semiconductor test and processing equipment; Cisco Systems, the largest provider of data networking products; Hewlett-Packard, a diversified provider of printers and computer products and services; and Avaya, a leading provider of corporate telephone systems. We redeployed the proceeds from these sales in other information technology stocks, including Corning, EMC, Apple Computer, Intel, Texas Instruments, and Motorola. HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE DURING THE REPORTING PERIOD? It is important to note that the Fund's weightings are largely a residual of our bottom-up stock-selection process and are affected by the Fund's careful sell discipline. Because our process identified numerous attractive stocks in the consumer discretionary sector, the Fund's exposure increased. We also increased the Fund's exposure to the energy sector. The strong run-up in the price of oil during the reporting period--along with the low probability that oil prices would drop meaningfully below $50 a barrel anytime soon--led us to increase the Fund's weighting in oil services stocks and stocks of companies that offer oil alternatives, such as coal. We reduced the Fund's weightings in consumer staples, industrials, and in information technology. In each case, the declines resulted from company-specific sales rather than any overall impression about the market or the economy. We also decreased the Fund's weighting in financials because of rising interest rates. HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD? As of October 31, 2005, the Fund had overweighted positions relative to the Russell 1000(R) Growth Index in consumer discretionary, energy, industrials, and materials. As of the same date, the Fund was underweighted relative to the Index in consumer staples, financials, health care, and information technology. At the end of the reporting period, the Fund had no holdings in telecommunications services or utilities.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Capital Appreciation Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Class A shares, whose distribution commenced on January 3, 1995, are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Distribution of Class B shares and Class C shares commenced on May 1, 1986 and September 1, 1998, respectively. Class I shares are not subject to sales charge. Distribution of Class I shares commenced on January 1, 2004. Class A shares, Class B, Class C and Class I shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions. Each class of shares other than Class I shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution or service fee. The Fund's investment objective is to seek long-term growth of capital. Dividend income, if any, is an incidental consideration. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (see Note 7). (C) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. 18 MainStay Capital Appreciation Fund The following table discloses the current year reclassifications between net investment loss and additional paid-in-capital arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> NET INVESTMENT ADDITIONAL LOSS PAID-IN CAPITAL $13,627,331 $(13,627,331) </Table> (E) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (F) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (G) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (H) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund.

NOTE 10--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay Capital Appreciation Fund was $3,205,000. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 21 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Capital Appreciation Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year period then ended.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's underperformance over several time periods, recent change of personnel on the portfolio management team serving the Fund, and the Subadvisor's implementation of plan intended to improve the Fund's performance. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees, in considering economies of scale, reviewed information showing that the Fund, though one of the largest series of the MainStay Funds, had not significantly increased in size during the past five years. The Trustees discussed the extent to which, in the event the Fund were to increase in size, economies of scale were projected by the Manager to be realized. They noted that the Fund's contractual management fee had been reduced by the breakpoint schedule applicable to the Fund that was intended to provide that the Fund's shareholders would 26 MainStay Capital Appreciation Fund share in benefits from economies of scale arising from the growth of Fund assets. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated expense ratio, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 27 PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that New York Life Investment Management LLC ("NYLIM") uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by calling 1-800-MAINSTAY (1-800-624-6782); (ii) by visiting the Fund's website at www.mainstayfunds.com; or (iii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /S/ CHRISTOPHER O. BLUNT Christopher O.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT VALUE ENDING ACCOUNT (BASED ON VALUE (BASED HYPOTHETICAL BEGINNING ON ACTUAL EXPENSES 5% RETURN EXPENSES ACCOUNT RETURNS AND PAID AND ACTUAL PAID VALUE EXPENSES) DURING EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,007.15 $ 6.83 $1,018.25 $ 6.87 - -------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,002.30 $10.60 $1,014.50 $10.66 - -------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,002.30 $10.60 $1,014.50 $10.66 - -------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,008.45 $ 5.01 $1,020.05 $ 5.04 - -------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Morgan and Joseph Portera of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 65% of its total assets in a diversified portfolio of domestic and foreign debt or debt-related securities issued by government and corporate issuers. The securities may be denominated in U.S. or foreign currencies and may have fixed, variable, floating, or inverse floating rates of interest. The Fund invests in various bond-market sectors including U.S. government securities (which may include mortgage-related and asset backed securities), foreign government securities and U.S. corporate and foreign corporate debt securities. The Fund may invest in high-yield securities, if available, in any of these sectors. Allocations across market sectors are based on current and projected economic and market conditions. In implementing this strategy, we seek to identify investment opportunities based on the financial condition and competitiveness of individual companies. In making allocation and sector decisions, we may rely on fundamental economic-cycle analysis. We may also consider credit quality and interest-rate trends. Investments may include bonds of established economies and emerging markets. WHAT SIGNIFICANT FACTORS AFFECTED THE BOND MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? The Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. This caused a sharp increase in the yields of short-term domestic issues. Strong inflows from Asian central banks helped support prices among longer-dated U.S. Treasurys and resulted in a substantial flattening of the yield curve during the reporting period. In the domestic bond market, yield spreads(1) between investment-grade corporate bonds and U.S. Treasurys continued to contract throughout the reporting period. The automotive sector was a notable exception, largely because of difficulties at Ford and General Motors that led Moody's and Standard & Poor's to downgrade their debt to high-yield (or "fallen angel") status. In the non-U.S. dollar market, currency exposure had a negative impact because the dollar rallied relative to most major currencies. Emerging markets remained resilient. With credit upgrades and increased institutional-investor participation, emerging-market spreads reached record lows relative to U.S. Treasurys. For most of the reporting period, U.S. high-yield issues saw tight spreads but little in the way of increased default risk. The inclusion of General Motors in the high-yield universe added volatility. HOW DID THE FUND PERFORM RELATIVE TO ITS PEERS DURING THE REPORTING PERIOD? In our estimation, the Fund's relative performance was adversely affected by its currency exposure and by a smaller weighting than peer funds in emerging-market debt. The Fund's airline holdings took a toll on the Fund's performance in the high-yield sector. Fortunately, the Fund had little exposure to the automotive industry in the investment-grade portion of the Fund's portfolio. WHAT WERE SOME OF THE MAJOR DECISIONS THAT AFFECTED THE FUND'S PERFORMANCE? We significantly altered the Fund's overall asset allocation during the 12-month reporting period. We substantially reduced the Fund's high-yield allocation. Over the same period, we increased the Fund's allocation to international bonds and its allocation to investment-grade debt. In the international-bond portion of the Fund, we put the new money to work in emerging-market dollar debt, which had a positive impact on the Fund's performance. Since high-yield securities outperformed investment-grade debt during the reporting period, the allocation shift detracted from the Fund's overall performance. Our decision to increase currency exposure also hurt the Fund's performance because the dollar continued to rise for most of the reporting period. Funds that invest in bonds are subject to interest rate, credit, and inflation risk and can lose principal when interest rates rise. Foreign securities may be subject to greater risks than U.S. investments, including currency fluctuations, less-liquid trading markets, greater price volatility, political and economic instability, less publicly available information, and changes in tax or currency laws or monetary policy. These risks are likely to be greater in emerging markets than in developed markets. High-yield securities ("junk bonds") are generally considered speculative because they present a greater risk of loss than higher-quality debt securities and may be subject to greater price volatility. The Fund may invest in derivatives, which may increase the volatility of the Fund's net asset value and may result in a loss to the Fund. The Fund may experience a portfolio turnover rate of over 100% and may generate short-term capital gains which are taxable. 1. The terms "spread" and "yield spread" may refer to the difference in yield between a specific security or type of security and comparable U.S. Treasury issues. The terms may also refer to the difference in yield between two specific securities or types of securities at a given time. 8 MainStay Diversified Income Fund WHAT SPECIFIC FACTORS LED YOU TO MAKE THE CHANGES IN THE FUND'S ALLOCATION? Each allocation change had its own logic. Early in the reporting period, our high-yield group became concerned about the tight yield spread between high-yield bonds and U.S. Treasurys. We were also concerned about the reduced quality of new issues in the high-yield market, which limited our source of new high-yield investments. As a result, we began to slowly rotate out of high-yield securities and into emerging-market and investment-grade debt. We did this by allocating new money to emerging-market and investment-grade securities and by making redemptions among high-yield holdings. We also increased cash in the high-yield portion of the Fund's portfolio. On the currency front, we concluded that the U.S. current account and budget deficits would come under increasing stress leading to a U.S. dollar sell-off. Early in the reporting period, we started adding exposure to the yen, the euro, and to a lesser degree the Canadian dollar. Having seen the U.S. dollar continue to rise against most foreign currencies, however, we recently elected to hedge part of the Fund's yen exposure to help protect against further downside risk. From the start of the reporting period our investment-grade group had been underweighted in the troubled auto sector. In May we sold the Fund's position in GMAC leaving only a small position in Ford Motor paper. As spreads continued to widen in the auto sector, high-yield investors began to take notice. Toward the end of the first calendar quarter of 2005, the high-yield group started to buy General Motors, adding GMAC and GM paper starting in March. HOW DID SPECIFIC PORTIONS OF THE FUND'S PORTFOLIO PERFORM DURING THE REPORTING PERIOD? Emerging-market debt was by far the Fund's best-performing asset class during the reporting period. Non-U.S. dollar debt with unhedged currency exposure was the worst-performing asset class. Exclusive of all fees and sales charges, the high-yield portion of the Fund's portfolio provided a total return of 6.32%, the international-bond portion returned 3.4%, and the domestic high-grade portion returned 1.7%. WERE THERE ANY SIGNIFICANT PURCHASES AND SALES DURING THE REPORTING PERIOD? In the international portion of the Fund's portfolio, we bought Brazilian and Mexican bonds in February and March. We took profits in Russian 30-year debt in September. Significant purchases in the high-yield portion of the Fund's portfolio included several GMAC issues during the second and third calendar quarters of 2005 and securities issued by Qwest in August 2005. HOW DID THE FUND PERFORM RELATIVE TO ITS BENCHMARK? The Fund compares itself to a Three-Index Composite that assumes equal investments in the Lehman Brothers(R) Aggregate Bond Index, the Credit Suisse First Boston(TM) High Yield Index, and the Citigroup Non-U.S. Dollar World Government Bond Index.(2) The Fund's performance relative to this benchmark was positive because the Fund's overall currency exposure was considerably less than the 33% implied by the non-currency-hedged Citigroup Non-U.S. Dollar World Government Bond Index. At the end of the reporting period, less than 15% of the Fund's assets carried currency exposure. Emerging-market debt, which contributed to the Fund's positive performance, is not significantly reflected in any of the three indices in the benchmark. Exclusive of all fees and sales charges, the high-yield portion of the Fund's portfolio had strong nominal performance and outperformed the Credit Suisse First Boston(TM) High Yield Index. Although on the same basis the investment-grade portion of the Fund's portfolio outperformed the Lehman Brothers(R) Aggregate Index, the nominal return was lower than that in the high-yield and international portions of the Fund's portfolio. 2.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Diversified Income Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Distribution of Class A shares and Class B shares commenced on February 28, 1997. Class C shares and Class I shares were initially offered on September 1, 1998 and January 2, 2004, respectively. Class A shares are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class I shares are not subject to sales charge. Class A, Class B, Class C and Class I shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions. Each class of shares other than Class I shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution or service fee. The Fund's investment objective is to provide current income and competitive overall return by investing primarily in domestic and foreign debt securities. The Fund invests in high yield securities (sometimes called "junk bonds"), which are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. These securities pay a premium--a high interest rate or yield--because of the increased risk of loss. These securities can also be subject to greater price volatility. The Fund also invests in foreign securities which carry certain risks that are in addition to the usual risks inherent in domestic instruments. These risks include those resulting from currency fluctuations, future adverse political and economic developments and possible imposition of currency exchange blockages or other foreign governmental laws or restrictions. These risks are likely to be greater in emerging markets than in developed markets. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country, industry or region. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below.

Debt securities are valued at prices supplied by a pricing agent or brokers selected by the Fund's Manager, whose prices reflect broker/dealer supplied valuations and electronic data processing techniques, if such prices are deemed by the Fund's Manager to be representative of market values, at the regular close of business of the New York Stock Exchange. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Options contracts are valued at the last posted settlement price on the market where such options are principally traded. Foreign currency forward contracts are valued at their fair market values determined on the basis of the mean between the last current bid and asked prices based on dealer or exchange quotations. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. At October 31, 2005, the Fund held securities with a value of $166,521 that were valued in such manner. Certain events may occur between the time that foreign markets close, on which securities held by the Fund principally trade, and the time at which the Fund's NAV is calculated. These events may include, but are not limited to, situations relating to a single issue in a market sector, significant fluctuations in U.S. or foreign markets, natural disasters, armed conflicts, governmental actions or other developments not tied directly to the securities markets. Should the Manager or Subadvisor conclude that such events may have effected the accuracy of the last price reported on the local foreign market, the Manager or Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of the local price to reflect the 30 MainStay Diversified Income Fund impact on the price of such securities as a result of such events. (B) FOREIGN CURRENCY FORWARD CONTRACTS. A foreign currency forward contract is an agreement to buy or sell currencies of different countries on a specified future date at a specified rate. During the period the forward contract is open, changes in the value of the contract are recognized as unrealized gains or losses by "marking to market" such contract on a daily basis to reflect the market value of the contract at the end of each day's trading. When the forward contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. The Fund enters into foreign currency forward contracts primarily to hedge its foreign currency denominated investments and receivables and payables against adverse movements in future foreign exchange rates or to try to enhance the Fund's returns. The use of foreign currency forward contracts involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statement of Assets and Liabilities. The contract amount reflects the extent of the Fund's involvement in these financial instruments. Risks arise from the possible movements in the foreign exchange rates underlying these instruments. The unrealized appreciation on forward contracts reflects the Fund's exposure at period end to credit loss in the event of a counterparty's failure to perform its obligations. (See Note 7) (C) PURCHASED AND WRITTEN OPTIONS. The Fund may write covered call and put options on its portfolio securities or foreign currencies. Premiums are received and are recorded as liabilities. The liabilities are subsequently adjusted and unrealized appreciation or depreciation is recorded to reflect the current value of the options written. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are cancelled in closing purchase transactions are added to the proceeds or netted against the amount paid on the transaction to determine the realized gain or loss. By writing a covered call option, in exchange for the premium, the Fund foregoes the opportunity for capital appreciation above the exercise price should the market price of the underlying security or foreign currency increase but, as long as the obligation as a writer continues, have retained the risk of loss should the price of the underlying security decline. By writing a covered put option, the Fund, in exchange for the premium, accepts the risk of decline in the market value of the underlying security or foreign currency below the exercise price. After writing a put option, the Fund may incur a loss equal to the difference between the exercise price of the option and the sum of the market value of the underlying security plus the premium received from the sale of the option. A call option may be covered by the call writer's owning the underlying security throughout the option period. A call option may also be covered by the call writer's maintaining liquid assets valued at greater than the exercise price of the call written, in a segregated account with its custodian. The Fund may purchase call and put options on its portfolio securities. The Fund may purchase call options to protect against an increase in the price of the security it anticipates purchasing. The Fund may purchase put options on its securities to protect against a decline in the value of the security or to close out covered written put positions. The Fund may also purchase options to seek to enhance returns. Risks may arise from an imperfect correlation between the change in market value of the securities held by the Fund and the prices of options relating to the securities purchased or sold by the Fund and from the possible lack of a liquid secondary market for an option. The maximum exposure to loss for any purchased option is limited to the premium initially paid for the option. (D) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 7). (E) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS. The Fund invests in loan assignments and loan participations. Loan assignments and participations are agreements to make money available (a "commitment") to a borrower in a specified amount, at a specified rate and within a specified time. Such loan assignments and participations are typically senior, secured and collateralized in nature. The Fund records an investment when the borrower withdraws money and records interest as earned. These loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or London InterBank Offered Rate (LIBOR). The loans in which the Fund invests are generally readily marketable, but may be subject to some restrictions on resale. The Fund may be contractually obligated to receive approval from the agent bank and/or borrower prior to the sale of these investments. The Fund assumes the credit risk of the Borrower, the Selling Participant and any other persons interpositioned www.MAINSTAYfunds.com 31 NOTES TO FINANCIAL STATEMENTS (CONTINUED) between the Fund and the Borrower ("Intermediate Participants"). In the event that the Borrower, Selling Participant or Intermediate Participants becomes insolvent or enters into bankruptcy, the Fund may incur certain costs and delays in realizing payment, or may suffer a loss of principal and/or interest. Unfunded commitments represent the remaining obligation of the Fund to the Borrower. At any point in time, up to the maturity date of the issue, the Borrower may demand the unfunded portion. These unfunded amounts are recorded in memorandum accounts. (F) MORTGAGE DOLLAR ROLLS. The Fund enters into mortgage dollar roll ("MDR") transactions in which it sells mortgage-backed securities ("MBS") from its portfolio to a counterparty from whom it simultaneously agrees to buy a similar security on a delayed delivery basis. The MDR transactions of the Fund are classified as purchase and sale transactions. The securities sold in connection with the MDRs are removed from the portfolio and a realized gain or loss is recognized. The securities the Fund has agreed to acquire are included at market value in the portfolio of investments and liabilities for such purchase commitments are included as payables for investments purchased. During the roll period, a Fund forgoes principal and interest on the securities. A Fund is compensated by the difference between the current sales price and the forward price for the future purpose as well as by the earnings on the cash proceeds of the initial sale. MDRs may be renewed without physical delivery of the securities subject to the contract. The Fund maintains a segregated account with its custodian containing securities from its portfolio having a value not less than the repurchase price, including accrued interest. MDR transactions involve certain risks, including the risk that the MBS returned to the Fund at the end of the roll, while substantially similar, could be inferior to what was initially sold to the counterparty. (G) RESTRICTED SECURITIES. A restricted security is a security which has been purchased through a private offering and cannot be resold to the general public without prior registration under the Securities Act of 1933 (the "1933 Act"). The Fund does not have the right to demand that such securities be registered. Disposal of these securities may involve time-consuming negotiations and expense and prompt sale at an acceptable price may be difficult. (See Note 7) (H) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (I) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends monthly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between accumulated distributions in excess of net investment income and accumulated net realized loss on investments arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> ACCUMULATED DISTRIBUTIONS IN ACCUMULATED NET EXCESS OF NET REALIZED LOSS ON INVESTMENT INCOME INVESTMENTS $623,069 $ (623,069) ------------------------------------ </Table> The reclassifications for the Fund are primarily due to premium amortization adjustments, straddles, paydown and foreign currency gain (loss). (J) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Income from payment-in-kind securities is recorded daily based on the effective interest method of accrual. The investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. 32 MainStay Diversified Income Fund (K) FOREIGN CURRENCY TRANSACTIONS. The books and records of the Fund are kept in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean between the buying and selling rates last quoted by any major U.S. bank at the following dates: (i) market value of investment securities, other assets and liabilities--at the valuation date, (ii) purchases and sales of investment securities, income and expenses--at the date of such transactions. The assets and liabilities are presented at the exchange rates and market values at the close of the period. The realized and unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. Net realized gain (loss) on foreign currency transactions represents net gains and losses on foreign currency forward contracts, net currency gains or losses realized as a result of differences between the amounts of securities sale proceeds or purchase cost, dividends, interest and withholding taxes as recorded on the Fund's books, and the U.S. dollar equivalent amount actually received or paid. Net currency gains or losses from valuing such foreign currency denominated assets and liabilities, other than investments, are reflected in unrealized foreign exchange gains or losses at period end exchange rates. (L) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (M) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (N) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.60% on assets up to $500 million and 0.55% on assets in excess of $500 million. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.30% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $19,479 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM voluntarily agreed to reimburse the expenses of the Fund so that total annual fund operating expenses do not exceed on an annualized basis 1.35% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $791,423, and waived its fee and/or reimbursed expenses in the amount of $87,293. www.MAINSTAYfunds.com 33 NOTES TO FINANCIAL STATEMENTS (CONTINUED) Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager paid the Subadvisor a monthly fee of 0.30% of the Fund's average daily net assets. To the extent that the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntary agreed to do so proportionately. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, other than Class I shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $31,598 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $284, $69,918 and $3,573, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $373,528. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. (F) CAPITAL. At October 31, 2005 NYLIFE Distributors held shares of Class B with a value of $7,584,384 which represents 10.6% of Class B net assets and 6.0% of the total Fund's net assets at October 31, 2005. (G) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $3,416 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $39,857 for the year ended October 31, 2005. NOTE 4--CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, The Bank of New York acted as custodian for the Fund. NOTE 5--FEDERAL INCOME TAX: As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> UNDISTRIBUTED ACCUMULATED OTHER TOTAL ORDINARY CAPITAL TEMPORARY UNREALIZED ACCUMULATED INCOME LOSSES DIFFERENCES DEPRECIATION LOSS $1,366,319 $(3,840,926) $(400,807) $(868,168) $(3,743,582) ---------------------------------------------------------------------- </Table> 34 MainStay Diversified Income Fund The difference between book-basis and tax-basis unrealized appreciation is primarily due to wash sale loss deferrals, deferral of losses on foreign currency forward contracts for tax purposes and interest on defaulted securities. At October 31, 2005, for federal income tax purposes, capital loss carryforwards of $3,840,926 were available as shown in the table below, to the extent provided by the regulations to offset future realized gains of the Fund through the years indicated. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to shareholders. <Table> <Caption> CAPITAL LOSS AMOUNT AVAILABLE THROUGH (000'S) 2008 $1,293 2009 864 2010 1,161 2011 523 ------------------------------------------- $3,841 ------------------------------------------- </Table> The Fund utilized $711,183 of capital loss carryforwards during the year ended October 31, 2005. The tax character of distributions paid during the years ended October 31, 2005 and 2004, shown in the Statement of Changes in Net Assets, were as follows: <Table> <Caption> 2005 2004 Distributions paid from: Ordinary Income $5,012,863 $6,238,744 - ------------------------------------------------------------- </Table> NOTE 6--PURCHASES AND SALES OF SECURITIES (IN 000'S): During the year ended October 31, 2005, purchases and sales of U.S. Government securities were $91,351 and $85,059, respectively.

NOTE 8--LINE OF CREDIT: The Fund and certain affiliated funds maintain a line of credit of $160,000,000 with a syndicate of banks in order to secure a source of funds for temporary purposes to meet unanticipated or excessive shareholder redemption requests. The funds pay a commitment fee, at an annual rate of .075% of the average commitment amount, regardless of usage, to The Bank of New York, which acts as agent to the syndicate.

NOTE 10--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completely responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those agreements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the Funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay Diversified Income Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. 38 MainStay Diversified Income Fund REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Diversified Income Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Diversified Income Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 www.MAINSTAYfunds.com 39 TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in managements presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's mid-range performance when compared over several time periods with funds concluded by Trustees to be peers of the Fund. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place www.MAINSTAYfunds.com 43 for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. 44 MainStay Diversified Income Fund PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that New York Life Investment Management LLC ("NYLIM") uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by calling 1-800-MAINSTAY (1-800-624-6782); (ii) by visiting the Fund's website at www.mainstayfunds.com; or (iii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /S/ CHRISTOPHER O. BLUNT Christopher O.

Total returns reflect change in share price, reinvestment of dividend and capital-gain distributions, and maximum applicable sales charges explained in this paragraph. The graphs assume an initial investment of $10,000 and reflect the deduction of all sales charges that would have applied for the period of investment. Class A shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1 fee of .25%. Class B shares are sold with no initial sales charge, are subject to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are subject to a CDSC of 1% if redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales charge or CDSC, have no annual 12b-1 fee, and are generally available to corporate and institutional investors with a minimum initial investment of $5 million. Class R1 shares are sold with no initial sales charge or CDSC and have no annual 12b-1 fee. Class R2 shares are sold with no initial sales charge or CDSC and have an annual 12b-1 fee of ..25%. Class R1 and R2 shares are available only through corporate-sponsored retirement programs, which include certain minimum program requirements. Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. The fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees.

The Russell Midcap(R) Value Index is an unmanaged index that measures the performance of those Russell Midcap(R) companies with lower price-to-book ratios and lower forecasted growth values. The Russell Midcap(R) Index is an unmanaged index that measures the performance of the 800 smallest companies in the Russell 1000(R) Index, which, in turn, is an unmanaged index that measures the performance of the 1,000 largest U.S. companies based on total market capitalization. Results assume reinvestment of all income and capital gains. The Russell Midcap(R) Value Index is considered to be the Fund's broad-based securities-market index for comparison purposes. An investment cannot be made directly into an index. 2. Lipper Inc. is an independent fund performance monitor.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested, to estimate the expenses that you paid during the six-months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,057.55 $ 7.00 $1,018.25 $ 6.87 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,054.10 $10.87 $1,014.50 $10.66 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,054.10 $10.87 $1,014.50 $10.66 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,059.75 $ 5.14 $1,020.05 $ 5.04 - --------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,059.25 $ 5.66 $1,019.55 $ 5.55 - --------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,057.70 $ 6.95 $1,018.30 $ 6.82 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Spellman of MacKay Shields LLC. CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 80% of its assets in common and preferred stock of companies with market capitalizations that, at the time of investment, are similar to those of companies in the Russell Midcap(R) Value Index.(1) The Fund normally invests at least 80% of its assets in securities that we believe are undervalued when purchased, pay cash dividends, and are listed on a national securities exchange or traded in the over-the-counter market. In implementing this strategy, we seek to identify investment opportunities based on the financial condition and competitiveness of individual companies. In particular, we look for equities that we deem to be undervalued based on a number of factors, including relative valuation, prospects for future earnings growth, ability to grow dividends, and corporate management. WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? During the 12-month reporting period, stocks generally advanced, despite political events and energy price fluctuations. Value stocks outperformed growth stocks at all capitalization levels. Crude-oil prices rallied to $69.81 per barrel and natural gas prices broke $14 per million Btu before backing off somewhat. Major hurricanes affected supply-and-demand dynamics by damaging oil rigs and petrochemical plants. The price of gasoline rose to more than $3 a gallon, which threatened to slow consumer spending. Although hurricane-related stocks--including retailers, insurers, and companies on the Gulf Coast--were weakened, the long-term economic impact appeared to be manageable. The Federal Open Market Committee raised the targeted federal funds rate eight times during the 12-month reporting period, with a 25-basis-point increase on each occasion. (A basis point is one-hundredth of a percentage point.) On October 31, 2005, the federal funds target rate stood at 3.75%. During the reporting period, the yield curve flattened to reflect concern over a potential recession. Yet the most recent gross-domestic-product data suggests that the overall economy has remained resilient. WHAT WERE SOME OF THE FUND'S STRONG PERFORMERS DURING THE REPORTING PERIOD? The top-five positive contributors to the Fund during the reporting period were all from the contract drilling segment of the energy sector. Transocean Energy, ENSCO International, GlobalSantaFe, Rowan, and Pride International each benefited from higher oil and natural gas prices. These companies also benefited from the perception that day rates may continue to rise if damage to the Gulf of Mexico's drilling infrastructure tightens drilling-rig supply. Earnings results at these companies came in better than expected throughout the reporting period, which raised expectations and drove stock prices higher. WHICH STOCKS DETRACTED FROM THE FUND'S RESULTS? Three stocks in the paper industry hurt the Fund's performance during the reporting period. We purchased shares of Canadian newsprint manufacturer Abitibi-Consolidated in March 2005, and the company's shares slid through October because of higher energy costs and weaker-than-expected demand. The Fund continued to hold the company's shares, how- ever, because we felt they were attractively valued. The company has begun to concentrate on share- holder value by monetizing some noncore operations and cutting excess capacity. Paper company Bowater was plagued by higher feed-stock costs, sluggish demand, product substitution, and excess capacity. We reduced the Fund's position in this stock because we felt that conditions were not likely to get materially better in the foreseeable future. Linerboard manufacturer Smurfit-Stone Container faced trends similar to those at Bowater and Abitibi-Consolidated. The company also had difficulty passing through higher costs. We reduced the Fund's position in Smurfit-Stone Container near the end of the reporting period. We initiated a Fund position in Molson Coors Brewing in March 2005. After the share price declined and recent merger synergies were slow to materialize, we decided to eliminate the position from the portfolio in July 2005. Mid-capitalization companies are generally less established and their stocks may be more volatile and less liquid than the securities of large companies. The Fund may experience a portfolio turnover rate of over 100% and may generate short-term capital gains which are taxable. 1. See footnote on page 5 for more information about the Russell Midcap(R) Value Index. 8 MainStay Mid Cap Value Fund HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD? As of October 31, 2005, the Fund held overweighted positions relative to the Russell Midcap(R) Value Index in energy, materials, and industrials. On the same date, the Fund was underweighted relative to the Index in financials, consumer discretionary, utilities, information technology, and health care.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Mid Cap Value Fund (the "Fund"), a diversified fund. The Fund currently offers six classes of shares, Class A shares, Class B shares, Class C shares, Class I shares, Class R1 shares and Class R2 shares. Distribution of Class A shares and Class B shares commenced on June 1, 1998. Class C shares were initially offered on September 1, 1998. Distribution of Class I shares, Class R1 shares and Class R2 shares commenced on January 2, 2004. Class A shares are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class I, Class R1 and Class R2 shares are not subject to a sales charge. The six classes of shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation, and other rights and conditions except that Class B shares and Class C shares are subject to higher distribution fee rates than Class A shares and Class R2 shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares and Class R1 shares are not subject to a distribution or service fee. Class R1 and Class R2 shares are authorized to pay to New York Life Investment Management LLC, its affiliates, or third-party service providers, as compensation for services rendered to shareholders of Class R1 or Class R2 shares, a shareholder service fee. The Fund's investment objective is to realize maximum long-term total return from a combination of capital appreciation and income. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (see Note 7.) (C) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (D) PURCHASED AND WRITTEN OPTIONS. The Fund may write covered call and put options on its portfolio securities or foreign currencies. Premiums are received and are recorded as liabilities. The liabilities are subsequently adjusted and unrealized appreciation or depreciation is recorded to reflect the current value of the options written. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are cancelled in closing purchase transactions are added to the proceeds or netted against the amount paid on the transaction to determine the realized gain or loss. By writing a covered call option, 18 MainStay Mid Cap Value Fund in exchange for the premium, the Fund foregoes the opportunity for capital appreciation above the exercise price should the market price of the underlying security or foreign currency increase but, as long as the obligation as a writer continues, have retained the risk of loss should the price of the underlying security decline. By writing a covered put option, the Fund, in exchange for the premium, accepts the risk of decline in the market value of the underlying security or foreign currency below the exercise price. After writing a put option, the Fund may incur a loss equal to the difference between the exercise price of the option and the sum of the market value of the underlying security plus the premium received from the sale of the option. A call option may be covered by the call writer's owning the underlying security throughout the option period. A call option may also be covered by the call writer's maintaining liquid assets valued at greater than the exercise price of the call written, in a segregated account with its custodian. The Fund may purchase call and put options on its portfolio securities. The Fund may purchase call options to protect against an increase in the price of the security it anticipates purchasing. The Fund may purchase put options on its securities to protect against a decline in the value of the security or to close out covered written put positions. The Fund may also purchase options to seek to enhance returns. Risks may arise from an imperfect correlation between the change in market value of the securities held by the Fund and the prices of options relating to the securities purchased or sold by the Fund and from the possible lack of a liquid secondary market for an option. The maximum exposure to loss for any purchased option is limited to the premium initially paid for the option. (E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between net investment loss, accumulated net realized gain on investments and additional paid-in-capital arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> ACCUMULATED NET NET REALIZED ADDITIONAL INVESTMENT GAIN ON PAID-IN- LOSS INVESTMENTS CAPITAL $1,263,215 $158,191 $(1,421,406) --------------------------------------- </Table> The reclassifications for the Fund are primarily due to the fact that net operating losses cannot be carried forward for federal income tax purposes, real estate investment trusts investments and foreign currency gain (loss). (F) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (G) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (H) FOREIGN CURRENCY TRANSACTIONS. The books and records of the Fund are kept in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean between the buying and selling rates last quoted by any major U.S. bank at the following dates: (i) market value of investment securities, other assets and liabilities--at the valuation date. (ii) purchases and sales of investment securities, income and expenses--at the date of such transactions. The assets and liabilities are presented at the exchange rates and market values at the close of the period. The www.MAINSTAYfunds.com 19 NOTES TO FINANCIAL STATEMENTS (CONTINUED) realized and unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. Net realized gain (loss) on foreign currency transactions represents net gains and losses on foreign currency forward contracts, net currency gains and losses realized as a result of differences between the amounts of securities sale proceeds or purchase cost, dividends, interest and withholding taxes as recorded on the Fund's books, and the U.S. dollar equivalent amount actually received or paid. Net currency gains or losses from valuing such foreign currency denominated assets and liabilities, other than investments, are reflected in unrealized foreign exchange gains or losses at year end exchange rates. (I) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (J) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.70% on assets up to $500 million and 0.65% on assets in excess of $500 million. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.35% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005 the Fund had $130,177 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM agreed to voluntarily reimburse the expenses of the Fund so that the total operating expenses would not exceed on an annualized basis 1.35% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. Prior to December 1, 2004, NYLIM agreed to voluntarily reimburse the expenses of the Fund so that the total operating expenses would not exceed on an annualized basis 1.65%, 2.40% and 2.40% of the average daily net assets of the Class A, Class B and Class C shares, respectively, and an equivalent amount for Class I, Class R1 and Class R2 shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $2,760,089, and waived its fee and/or reimbursed expenses in the amount of $259,768. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of 0.35% of the average daily net assets of the Fund. To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to Class A, Class B, Class C, and Class R2 shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A and Class R2 Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A and Class R2 shares, which is an expense of the Class A and Class R2 shares of the 20 MainStay Mid Cap Value Fund Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. The Fund has adopted a shareholder services plan with respect to Class R1 and Class R2 shares. Under the terms of this plan, Class R1 and Class R2 shares are authorized to pay to NYLIM, its affiliates, or independent third-party providers, as compensation for services rendered, a shareholder services fee at the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2 shares. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $96,303 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $11,626, $263,868 and $5,290, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $1,365,226. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. (F) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $10,396 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $66,097 for the year ended October 31, 2005. NOTE 4--CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, The Bank of New York acted as custodian for the Fund. NOTE 5--FEDERAL INCOME TAX: As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> ACCUMULATED NET TOTAL REALIZED GAIN ON UNREALIZED ACCUMULATED INVESTMENTS APPRECIATION GAIN $26,300,371 $55,485,816 $81,786,187 --------------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to wash sale deferrals.

NOTE 10--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay Mid Cap Value Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. 22 MainStay Mid Cap Value Fund REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Mid Cap Value Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Mid Cap Value Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 www.MAINSTAYfunds.com 23 TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's underperformance relative to certain measures over several time periods and the Subadvisor's plan designed to improve performance, in part, through the implementation of measures intended to reduce the volatility of the Fund's investment portfolio. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distribut- www.MAINSTAYfunds.com 27 ing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. 28 MainStay Mid Cap Value Fund FEDERAL INCOME TAX INFORMATION (UNAUDITED) The Fund is required by the Internal Revenue Code to advise shareholders within 60 days of the Fund's fiscal year end (October 31, 2005) as to the federal tax status of dividends paid by the Fund during such fiscal year.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ CHRISTOPHER O. BLUNT Christopher O.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED ON HYPOTHETICAL BEGINNING ON ACTUAL EXPENSES 5% RETURN EXPENSES ACCOUNT RETURNS AND PAID AND ACTUAL PAID VALUE EXPENSES) DURING EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,078.15 $ 7.49 $1,017.85 $ 7.27 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,074.70 $11.40 $1,014.10 $11.07 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,074.70 $11.40 $1,014.10 $11.07 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Saxon of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests primarily in high-yield securities, including debt securities issued by governments, and their agencies and authorities, and corporations that are located in at least three different countries. The Fund focuses on debt securities that generally are rated in the lower rating categories of Moody's or S&P(1). The Fund principally invests in emerging markets, but may also invest in established economies. In implementing this strategy, we seek to identify investment opportunities with an approach that includes country selection, local currency evaluation, and individual security analysis based on such factors as financial condition and competitiveness. We may consider a country's political stability, currency exchange rates, interest rates, inflation, relative economic growth, and governmental policies. During the reporting period, all of the assets and liabilities of MainStay International Bond Fund were transferred to MainStay Global High Income Fund in exchange for shares of MainStay Global High Income Fund. WHAT FACTORS INFLUENCED EMERGING-MARKET DEBT DURING THE 12-MONTH REPORTING PERIOD? By and large, emerging-market debt performed within our expectations during the period, buoyed by higher relative yields and continued improvement in credit fundamentals. While credit risk remained a concern, the additional yield offered by emerging-market securities continued to compensate buyers, and during the 12-month period ended October 31, 2005, emerging-market debt outperformed most other fixed-income asset classes. Several other factors also influenced the market during the reporting period. Tighter monetary policy in the U.S. caused the yield curve to flatten, as short-term yields rose while longer-term yields remained virtually unchanged. WHAT ISSUES AFFECTED THE MANAGEMENT OF THE FUND DURING THE 12-MONTH REPORTING PERIOD? For much of the reporting period, we concentrated the portfolio on securities with longer-term maturities and maintained a slightly longer duration than that of the Fund's benchmark, the JPMorgan EMBI Global Diversified Index.(2) The prices of soft and hard commodities continued to rise across the board during the reporting period. Several events strengthened the surge in prices. Major hurricanes in the United States disrupted refinery production and pushed oil and gas prices higher. Even selected agreements by the Organization of the Petroleum Exporting Countries to increase production had little if any effect on lowering energy prices. Higher prices benefited emerging-market oil exporters such as Mexico, Russia, and Venezuela. Precious-metals prices rose as demand from China and India continued to expand. Higher commodity prices benefited several investments in the Fund, including metals & mining companies Companhia Siderurgica Nacional in Brazil and Southern Peru Copper. HOW DID POLITICAL FACTORS AFFECT THE FUND? In emerging markets, political risk is always an issue. During the reporting period, there was considerable discussion about the possibility of Turkey becoming a member of the European Union. We saw a regime change in Ecuador. In Brazil, there was the usual "scandal sheet" of who took money and who benefited from what. In Russia, transparency and the rule of law came into question when President Putin used his influence to effectively renationalize parts of the oil and natural gas industry. Foreign securities may be subject to greater risks than U.S. investments, including currency fluctuations, less-liquid trading markets, greater price volatility, political and economic instability, less publicly available information, and changes in tax or currency laws or monetary policy. These risks are likely to be greater in emerging markets than in developed markets. High-yield securities ("junk bonds") are generally considered speculative because they present a greater risk of loss than higher-quality debt securities and may be subject to greater price volatility. The Fund may invest in derivatives, which may increase the volatility of the Fund's net asset value and may result in a loss to the Fund. Funds that invest in bonds are subject to credit, inflation, and interest-rate risk and can lose principal value when interest rates rise. The Fund may experience a portfolio turnover rate of over 100% and may generate short-term capital gains which are taxable. 1. Bonds rated B by Moody's Investors Service are deemed by Moody's to generally lack characteristics of the desirable investment. According to Moody's, assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small. Debt rated B by Standard & Poor's is deemed by Standard & Poor's to be more vulnerable to nonpayment than obligations rated BB, but it is the opinion of Standard & Poor's that the obligor currently has the capacity to meet its financial commitment on the obligation. Standard & Poor's believes that adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation. When applied to Fund holdings, ratings are based solely on the creditworthiness of the bonds in the portfolio and are not meant to represent the security or safety of the Fund. 2.

But clearly the market has matured. Prices did drop for specific issuers, such as those in Ecuador, but the securities quickly recovered. Over the past several years, emerging market government and corporate issuers have strengthened their balance sheets. With net debt reductions during the past 12 months, issuers hoping to extend the average maturity of their external debt have taken advantage of strong demand and historically low yields to do so. Over the years, many issuers that lacked access to the capital markets (e.g., Mexico in 1994 and Russia in 1998) have faced difficulties when they needed to roll over short-term debt. With prudent debt management and rising international reserves, however, this scenario is much less likely for most issuers. HOW DID YOU POSITION THE FUND'S PORTFOLIO IN THIS ENVIRONMENT? Regardless of the market environment, our philosophy is to emphasize undervalued assets using a long-term perspective. Since emerging-market debt had already enjoyed several years of above-average performance, we entered the reporting period believing that volatility was likely to increase, at least over the short term. As long as fundamentals continued to improve, however, we planned to remain almost fully invested. As new money came into the Fund, we quickly sought to invest it--at least until October 2005. As the U.S. Treasury sell-off gained momentum, we became more defensive and increased the Fund's cash position. For most of the 12 months ended October 31, 2005, we maintained our major themes, focusing on commodity-based issuers and improving corporate credits. A major shift for the Fund during the reporting period was our decision to add local currency debt to the Fund's portfolio. As of October 31, 2005, local currency emerging-market debt was approximately 3% of the Fund's net assets and was split across the Mexican peso, the Brazilian real, the Argentine peso, the Turkish lira, and the Colombian peso. In most cases, we have been attracted to these currencies because of high real interest rates and strong current-account data. Following the debt exchange in Argentina, we concluded that the local currency offered better risk/reward characteristics than the external debt. Since the Fund purchased the local currency debt, these bonds have contributed positively to the Fund's overall return. The Fund's strategically overweighted position in Russian assets also enhanced results. The yield premium investors have demanded to own Russian debt has declined 145 basis points over the reporting period. (A basis point is one-hundredth of a percentage point.) The financial woes of the U.S. auto sector have received considerable publicity. In August, we viewed this as an opportunity and elected to add a small position in General Motors Acceptance Corp. debt to the Fund's portfolio. We felt that under any conceivable scenario, a commitment to GMAC would be well invested. In particular, the Fund purchased some long-term GMAC debt, and the holding has risen since it was acquired. The increase came on news that General Motors was looking for a strategic buyer for a majority of GMAC, a move that might help the subsidiary regain an investment-grade rating. As we stated earlier, we raised the Fund's cash position toward the end of the reporting period. We also reduced the Fund's exposure to Russian debt. Given the rally in the corporate sector, we felt that at current spread levels it would be prudent to reduce this overweighted position. Part of the proceeds went into cash and a portion was used to purchase Mexican dollar debt.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Global High Income Fund (the "Fund"). The Fund currently offers three classes of shares. Distribution of Class A shares and Class B shares commenced on June 1, 1998. Class C shares were initially offered on September 1, 1998 Class A shares are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class A shares, Class B shares and Class C shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions except that the Class B shares and Class C shares are subject to higher distribution fee rates. Each class of shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. The Fund's investment objective is to seek to provide maximum current income by investing primarily in high yield debt securities of non-U.S. issuers. Capital appreciation is a secondary objective. The Fund is "non-diversified," which means that it may invest a greater percentage of its assets than diversified funds in a particular issuer. This may make it more susceptible than diversified funds to risks associated with an individual issuer, and to single economic, political or regulatory occurrences. The Fund's principal investments include high yield securities (sometimes called "junk bonds"), which are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. These securities pay a premium--a high interest rate or yield --because of the increased risk of loss. These securities can also be subject to greater price volatility. The Fund also invests in foreign securities which carry certain risks that are in addition to the usual risks inherent in domestic instruments. These risks include those resulting from currency fluctuations, future adverse political and economic developments and possible imposition of currency exchange blockages or other foreign governmental laws or restrictions. These risks are likely to be greater in emerging markets than in developed markets. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country, industry or region. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Debt securities are valued at prices supplied by a pricing agent or brokers selected by the Fund's Manager, whose prices reflect broker/dealer supplied valuations and electronic data processing techniques, if such prices are deemed by the Fund's Manager to be representative of market values, at the regular close of business of the New York Stock Exchange. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Foreign currency forward contracts are valued at their fair market values determined on the basis of the mean between the last current bid and asked prices based on dealer or exchange quotations. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. At October 31, 2005, the Fund held securities with a value of $1,791,597 that were valued in such manner. Certain events may occur between the time that foreign markets close, on which securities held by the Fund principally trade, and the time at which the Fund's NAV is calculated. These events may include, but are not limited to, situations relating to a single issue in a market sector, significant fluctuations in U.S. or foreign markets, natural disasters, armed conflicts, governmental actions or other developments not tied directly to the securities markets. Should the Manager or Subadvisor conclude that such events may have effected the accuracy of the last price reported on the local foreign market, the Manager or Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of the local price to reflect the 20 MainStay Global High Income Fund impact on the price of such securities as a result of such events. (B) FOREIGN CURRENCY FORWARD CONTRACTS. A foreign currency forward contract is an agreement to buy or sell currencies of different countries on a specified future date at a specified rate. During the period the forward contract is open, changes in the value of the contract are recognized as unrealized gains or losses by "marking to market" such contract on a daily basis to reflect the market value of the contract at the end of each day's trading. When the forward contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. The Fund enters into foreign currency forward contracts primarily to hedge its foreign currency denominated investments and receivables and payables against adverse movements in future foreign exchange rates or to try to enhance the Fund's returns. The use of foreign currency forward contracts involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statement of Assets and Liabilities. The contract amount reflects the extent of the Fund's involvement in these financial instruments. Risks arise from the possible movements in the foreign exchange rates underlying these instruments. The unrealized appreciation on forward contracts reflects the Fund's exposure at period end to credit loss in the event of a counterparty's failure to perform its obligations. ( See Note 6.) (C) RESTRICTED SECURITIES. A restricted security is a security which has been purchased through a private offering and cannot be resold to the general public without prior registration under the Securities Act of 1933 (the "1933 Act"). The Fund does not have the right to demand that such securities be registered. Disposal of these securities may involve time-consuming negotiations and expense and prompt sale at an acceptable price may be difficult. (See Note 6.) (D) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 6.) (E) LOAN PARTICIPATIONS AND COMMITMENTS. The Fund invests in loan participations. Loan participations are agreements to make money available (a "commitment") to a borrower in a specified amount, at a specified rate and within a specified time. Such loan participations are typically senior, secured and collateralized in nature. The Fund records an investment when the borrower withdraws money and records interest as earned. These loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or London InterBank Offered Rate (LIBOR). The loans in which the Fund invests are generally readily marketable, but may be subject to some restrictions on resale. The Fund may be contractually obligated to receive approval from the agent bank and/or borrower prior to the sale of these investments. The Fund assumes the credit risk of the Borrower, the Selling Participant and any other persons interpositioned between the Fund and the Borrower ("Intermediate Participants"). In the event that the Borrower, Selling Participant or Intermediate Participants becomes insolvent or enters into bankruptcy, the Fund may incur certain costs and delays in realizing payment, or may suffer a loss of principal and/or interest. Unfunded commitment represent the remaining obligation of the Fund to the Borrower. At any point in time, up to the maturity date of the issue, the Borrower may demand the unfunded portion. These unfunded amounts are recorded in memorandum accounts. (F) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (G) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends monthly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between accumulated loss, accumulated net realized gain on investments and additional paid-in capital arising www.MAINSTAYfunds.com 21 NOTES TO FINANCIAL STATEMENTS (CONTINUED) from permanent differences, net assets at October 31, 2005, are not affected. <Table> <Caption> ACCUMULATED UNDISTRIBUTED NET REALIZED NET INVESTMENT LOSS ON ADDITIONAL INCOME INVESTMENTS PAID-IN-CAPITAL $ 6,253,280 $ (6,250,452) $ (2,828) </Table> The reclassifications for the Fund are primarily due to premium amortization adjustments, foreign currency gain (loss), and taxable over distributions of dividends. (H) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Interest income is accrued as earned. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Income from payment-in-kind securities is recorded daily based on the effective interest method of accrual. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (I) FOREIGN CURRENCY TRANSACTIONS. The books and records of the Fund are kept in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean between the buying and selling rates last quoted by any major U.S. bank at the following dates: (i) market value of investment securities, other assets and liabilities--at the valuation date, (ii) purchases and sales of investment securities, income and expenses--at the date of such transactions. The assets and liabilities are presented at the exchange rates and market values at the close of the period. The realized and unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. The unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. Net realized gain (loss) on foreign currency transactions represents net gains and losses on foreign currency forward contracts, net currency gains or losses realized as a result of differences between the amounts of securities sale proceeds or purchase cost, dividends, interest and withholding taxes as recorded on the Fund's books, and the U.S. dollar equivalent amount actually received or paid. Net currency gains or losses from valuing such foreign currency denominated assets and liabilities, other than investments, are reflected in unrealized foreign exchange gains or losses at period end exchange rates. (J) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (K) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. Certain amounts have been reclassified to conform to current year presentation. Such reclassifications had no effect on the Fund's net income or capital. (L) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. 22 MainStay Global High Income Fund The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.70% on assets up to $500 million and 0.65% on assets over $500 million. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.40% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $38,120 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005, (and after December 1, 2004), NYLIM voluntarily agreed to reimburse the expenses of the Fund so that total annual fund operating expenses would not exceed on an annualized basis 1.51% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. Prior to December 1, 2004, the manager voluntarily agreed to reimburse the expenses of the Fund so that total annual fund operating expenses would not exceed on an annualized basis 1.70%, 2.45% and 2.45% of the average daily net assets of the Class A, Class B, and Class C shares, respectively. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $955,904, and reimbursed expenses in the amount of $38,120. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of 0.35% of the average daily net assets of the Fund. To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $54,775 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $1,239, $59,632 and $15,023, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $408,624. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. www.MAINSTAYfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) (F) CAPITAL. At October 31, 2005, New York Life held shares of Class A with a net asset values of $17,623,861.

Fees for these services provided to the Fund by the Manager amounted to $40,322 for the year ended October 31, 2005. NOTE 4--CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund.

NOTE 11--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completely responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those agreements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the Funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay Global High Income Fund was $11,000. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter, and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. 26 MainStay Global High Income Fund REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Global High Income Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Global High Income Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 www.MAINSTAYfunds.com 27 TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's better-than-average performance when compared over several time periods with funds concluded by Trustees to be peers of the Fund. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual www.MAINSTAYfunds.com 31 breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. 32 MainStay Global High Income Fund FEDERAL INCOME TAX INFORMATION (UNAUDITED) The Fund is required by the Internal Revenue Code to advise shareholders within 60 days of the Fund's fiscal year end (October 31, 2005) as to the federal tax status of dividends paid by the Fund during such fiscal year.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /S/ CHRISTOPHER O. BLUNT Christopher O.

Total returns reflect change in share price, reinvestment of dividend and capital-gain distributions, and maximum applicable sales charges explained in this paragraph. The graphs assume an initial investment of $10,000 and reflect the deduction of all sales charges that would have applied for the period of investment. Class A shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1 fee of .25%. Class B shares are sold with no initial sales charge, are subject to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are subject to a CDSC of 1% if redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%. Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. The fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. From inception (5/1/86) through 12/31/94 (for Class A, first offered 1/3/95) and 8/31/98 (for Class C, first offered 9/1/98), performance of Class A and C shares includes the historical performance of Class B shares adjusted to reflect the applicable sales charge (or CDSC) and fees and expenses for Class A and C shares.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Spellman of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 80% of its assets in convertible securities such as bonds, debentures, corporate notes, and preferred stocks or other securities that are convertible into common stock or the cash value of a stock or a basket or index of equity securities. The Fund takes a flexible approach by investing in a broad range of securities of a variety of companies and industries. The Fund invests in high-yield debt securities and may invest without restriction in securities rated BB or B by S&P or Ba or B by Moody's.(1) The balance of the Fund may be invested or held in nonconvertible debt, equity securities that do not pay regular dividends, U.S. government securities, and cash or cash equivalents. In selecting convertible securities for purchase or sale, we take into account a variety of investment considerations, including the potential return of the common stock, credit risk, projected interest return, and the premium for the convertible security relative to the underlying common stock. We may sell a security if we no longer believe it will contribute to meeting the investment objective of the Fund. WHAT FACTORS INFLUENCED THE CONVERTIBLE BOND MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? Convertible bonds are hybrid instruments whose results depend on the performance of related equity and fixed-income markets. Although the stock market was volatile during the reporting period, the S&P 500(R) Index advanced 8.72% during the 12 months ended October 31, 2005. During the same period, the Federal Open Market Committee raised the federal funds target rate eight times, with a 25-basis-point increase on each occasion. (A basis point is one-hundredth of a percentage point.) Rising interest rates and widening credit spreads depressed the value of straight corporate debt and convertible bonds. For the 12-month period, energy equipment & services convertibles were strong, while airline and automotive convertibles were weak. HOW DID THE FUND PERFORM RELATIVE TO THE CONVERTIBLE MARKET AS A WHOLE? Excluding all sales charges, all of the Fund's share classes outperformed the Merrill Lynch All Convertible Securities Index,(2) the Fund's primary benchmark, during the 12 months ended October 31, 2005. The Fund's outperformance resulted largely from security and sector selection. Continuing a theme from last year, the Fund remained heavily overweighted in the energy equipment & services industry, with large positions in the convertible bonds of Halliburton, Schlumberger, and Pride International, all of which contributed positively to the Fund's performance. Specific investments in other sectors also outperformed the Fund's primary benchmark. Automotive and airlines issues tended to underperform, so our decision to underweight the Fund in these areas helped relative performance. WHICH OF THE FUND'S SECURITIES WERE STRONG PERFORMERS DURING THE REPORTING PERIOD? The best performer for the Fund in terms of absolute dollar gain was Whole Foods Markets, followed by High-yield securities ("junk bonds") are generally considered speculative because they present a greater risk of loss than higher-quality debt securities and may be subject to greater price volatility. Issuers of convertible securities may not be as financially strong as those issuing securities with higher credit ratings and may be more vulnerable to changes in the economy. If an issuer stops making interest payments, principal payments, or both on its convertible securities, these securities may become worthless and the Fund could lose its entire investment in them. 1. Debt rated BB by Standard & Poor's is deemed by Standard & Poor's to be less vulnerable to nonpayment than other speculative issues. In the opinion of Standard & Poor's, however, debt rated BB faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation. Debt rated B by Standard & Poor's is deemed by Standard & Poor's to be more vulnerable to nonpayment than obligations rated BB, but it is the opinion of Standard & Poor's that the obligor currently has the capacity to meet its financial commitment on the obligation. Standard & Poor's believes that adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation. Bonds rated Ba by Moody's Investors Service are judged by Moody's to have speculative elements, and Moody's believes that the future of the bonds cannot be considered well- assured. Moody's believes that often, the protection of interest and principal payments on such bonds may be very moderate and thereby not well safeguarded during both good and bad times in the future. According to Moody's, uncertainty of position characterizes bonds in this class. Bonds rated B by Moody's Investors Service are deemed by Moody's to generally lack characteristics of the desirable investment. According to Moody's, assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small. When applied to Fund holdings, ratings are based solely on the creditworthiness of the bonds in the portfolio and are not meant to represent the security or safety of the Fund. 2. See footnote and table on page 4 for more information about the Merrill Lynch All Convertible Securities Index. www.MAINSTAYfunds.com 7 Halliburton, Pride International, and Teva Pharmaceutical Industries. Whole Foods Markets benefited from same-store sales and earnings that remained well above analysts' expectations. We have confidence in the company's excellent management, fundamental business, pristine balance sheet, and excess cash flow. High energy prices and increased exploration and production activity benefited energy equipment & services companies Halliburton, Pride International, and Schlumberger. The share prices and convertible bonds of these companies rose sharply during the reporting period. Convertible bonds of Teva Pharmaceutical Industries advanced on positive developments in the generic drug market. The company obtained the right to distribute generic Allegra for allergies and generic Effexor for depression. A court decision granted Teva Pharmaceutical Industries the right to be the exclusive generic seller of Pravachol, a drug developed by Bristol-Meyers Squibb. Other strong performers included Sirius Satellite Radio, Amerada Hess, and Chesapeake Energy. Sirius Satellite Radio convertibles advanced on faster-than- expected subscriptions. In January 2006, radio personality Howard Stern will begin airing on Sirius, which provides a variety of commercial-free music and talk offerings. Amerada Hess and Chesapeake Energy, two oil & gas exploration & production companies, benefited from high oil and natural gas prices. Since U.S. refining capacity has not increased in decades and demand for gasoline and heating oil has remained high, refining operations at Amerada Hess enjoyed strong margins. WHICH SECURITIES DETRACTED FROM THE FUND'S PERFORMANCE? In terms of dollars lost, the Fund's worst-performing position was a convertible bond of biotechnology company Elan Capital. Other detractors included securities of Lucent Technologies, Ford Motor, International Paper, and Flextronics International. Elan Capital's common stock tumbled in February 2005 when a recently introduced multiple sclerosis therapy, Tysabri, was pulled from the market. The Fund held convertible bonds and convertible preferred shares of Lucent Technologies, which declined when the company's profitability failed to meet investor expectations. Although the Fund was underweighted in the automobile industry, a Ford Motor convertible preferred suffered when the company faced poor vehicle sales, weak resale values, and retiree and health care costs that were above the industry's averages. International Paper's convertible bonds remained weak while the market continued to wait for the paper & forest products industry to feel the combined effects of global economic growth and high commodity prices. We recently sold some of our other forest products holdings, such as Bowater and Smurfit Stone Container, but the Fund continues to hold International Paper. Flextronics International provides contract manufacturing services for electronics products. The company's stock and convertible bonds declined sharply in October 2005 after the company reported disappointing sales and earnings. We continue to hold the company's convertible bonds because we believe the securities have limited downside risk. WERE THERE ANY SIGNIFICANT PURCHASES DURING THE FUND'S FISCAL YEAR? We added to the Fund's convertible bond position in Hilton Hotels on strong lodging-industry fundamentals. Hilton derives a high percentage of its revenues from New York and Hawaii, which are strong mar- kets, and the company is generating large amounts of free cash flow because nearly all of the revenue from increased room rates falls to the bottom line. We purchased Diamond Offshore Drilling convertible bonds to replace the Fund's holdings in BJ Services, which were called by the issuer. Diamond Offshore, which owns drilling rigs and leases them to exploration & production companies, has benefited from new leases, higher day rates, and the ongoing search for additional energy reserves. Amgen is a leading biotechnology company, perhaps best known for products that help oncology and dialysis patients boost red-blood-cell production. The company's promising pipeline of colon cancer, osteoporosis, and arthritis offerings is expected to help Amgen's share price rise, and we purchased the company's convertible bonds to participate in the upside potential. The bonds have an attractive put feature that significantly reduces downside risk without limiting upside potential. The Fund added to its position in Amerada Hess convertible preferred shares to take advantage of several potential catalysts that may increase the price of the securities. The company's hedging strategies and its plans to return operations to Libya may help the company's long-term outlook. We purchased Amazon.com convertible bonds for the Fund because they offer high current yield, limited downside risk, and maturity in less than four years. Although we are not bullish on the stock, the bonds are not particularly sensitive to Amazon.com's common stock performance. We believe that with 8 MainStay Convertible Fund Amazon.com's excellent balance sheet, the bonds will be easily paid off when they mature. WERE THERE ANY SIGNIFICANT SALES DURING THE REPORTING PERIOD? We sold the Fund's Burlington Northern Santa Fe convertible bonds because we believed that the share price fully reflected the positive outlook for the company's rail transportation business. We eliminated the Fund's position in Goodyear Tire & Rubber convertible bonds when we felt that the shares were fully valued. Full valuation also accounted for our sales of the Fund's convertible preferred shares of Northrop Grumman. When Symantec announced its intent to acquire software company Veritas Software, we sold the Fund's position in Symantec convertible bonds. In our opinion, the acquisition signaled that Symantec's core business, security software, was slowing. We sold the Fund's convertible preferred shares of Fannie Mae after a substantial decline in the company's common share price. Although the Fund's defensive position was not hurt as much as the common stock, we saw limited upside potential in the preferred. HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD? With the sale of Navistar and Cummins, which we believe had little remaining upside potential, the Fund's weighting in industrial/cyclicals declined during the reporting period. Sales of forest products holdings largely accounted for a drop in our allocation to the materials sector. The Fund's weighting in energy declined slightly from the beginning of the reporting period to the end of October. In July, the Fund's aggregate energy holdings approached a level that we felt was too high for a diversified Fund. The Fund's allocation to financials increased during the reporting period. The Fund purchased significant positions in convertible bonds of US Bancorp and Sallie Mae that offered substantial upside participation in the respective companies' common stock with virtually no downside participation or interest-rate risk. The Fund more than doubled its telecommunication services allocation from the beginning of the period to the end. We increased the Fund's Verizon convertible-bond holdings and initiated a position in NII Holdings, which provides mobile communications services in Latin America. HOW DID THE FUND'S WEIGHTINGS COMPARE WITH THOSE OF THE MERRILL LYNCH ALL CONVERTIBLE SECURITIES INDEX? As of October 31, 2005, the Fund was significantly overweighted in energy relative to the Merrill Lynch All Convertible Securities Index. On the same date, the Fund was substantially underweighted in technology, because we felt that most technology companies were selling at fairly high valuations given their cyclical nature and less-than-stellar fundamentals. The Fund was overweighted in consumer staples, primarily because of our large position in Whole Foods Markets. Other sectors did not deviate materially from the Index. In health care, industrials, and materials, the Fund's weightings were slightly lower than those of the Fund's benchmark. In telecommunications, financials, and utilities, the Fund's weightings were slightly higher than those of the Merrill Lynch All Convertible Securities Index.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Convertible Fund (the "Fund"), a diversified fund. The Fund currently offers three classes of shares. Class A shares, whose distribution commenced on January 3, 1995, are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Distribution of Class B shares and Class C shares commenced on May 1, 1986 and September 1, 1998, respectively. Class A shares, Class B shares and Class C shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions except that the Class B shares and Class C shares are subject to higher distribution fee rates. Each class of shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. The Fund's investment objective is to seek capital appreciation together with current income. The Fund invests in high yield securities (sometimes called "junk bonds"), which are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. These securities pay a premium -- a high interest rate or yield -- because of the increased risk of loss. These securities can also be subject to greater price volatility. The Fund also invests in foreign securities which carry certain risks that are in addition to the usual risks inherent in domestic instruments. These risks include those resulting from currency fluctuations, future adverse political and economic developments and possible imposition of currency exchange blockages or other foreign governmental laws or restrictions. These risks are likely to be greater in emerging markets than in developed markets. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country, industry or region. NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Debt securities are valued at prices supplied by a pricing agent or brokers selected by the Fund's Manager, whose prices reflect broker/dealer supplied valuations and electronic data processing techniques, if such prices are deemed by the Fund's Manager to be representative of market values, at the regular close of business of the New York Stock Exchange. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Options contracts are valued at the last posted settlement price on the market where such options are principally traded. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. At October 31, 2005, the Fund held securities with a value of $1,457 that were valued in such manner. Certain events may occur between the time that foreign markets close, on which securities held by the Fund principally trade, and the time at which the Fund's NAV is calculated. These events may include, but are not limited to, situations relating to a single issue in a market sector, significant fluctuations in U.S. or foreign markets, natural disasters, armed conflicts, governmental actions or other developments not tied directly to the securities markets. Should the Manager or Subadvisor conclude that such events may have effected the accuracy of the last price reported on the local foreign market, the Manager or Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of the local price to reflect the impact on the price of such securities as a result of such events. 20 MainStay Convertible Fund (B) FOREIGN CURRENCY FORWARD CONTRACTS. A foreign currency forward contract is an agreement to buy or sell currencies of different countries on a specified future date at a specified rate. During the period the forward contract is open, changes in the value of the contract are recognized as unrealized gains or losses by "marking to market" such contract on a daily basis to reflect the market value of the contract at the end of each day's trading. When the forward contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. The Fund enters into foreign currency forward contracts primarily to hedge its foreign currency denominated investments and receivables and payables against adverse movements in future foreign exchange rates or to try to enhance the Fund's returns. The use of foreign currency forward contracts involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statement of Assets and Liabilities. The contract amount reflects the extent of the Fund's involvement in these financial instruments. Risks arise from the possible movements in the foreign exchange rates underlying these instruments. The unrealized appreciation on forward contracts reflects the Fund's exposure at period end to credit loss in the event of a counterparty's failure to perform its obligations. (C) PURCHASED AND WRITTEN OPTIONS. The Fund may write covered call and put options on its portfolio securities or foreign currencies. Premiums are received and are recorded as liabilities. The liabilities are subsequently adjusted and unrealized appreciation or depreciation is recorded to reflect the current value of the options written. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are cancelled in closing purchase transactions are added to the proceeds or netted against the amount paid on the transaction to determine the realized gain or loss. By writing a covered call option, in exchange for the premium, the Fund foregoes the opportunity for capital appreciation above the exercise price should the market price of the underlying security or foreign currency increase but, as long as the obligation as a writer continues, have retained the risk of loss should the price of the underlying security decline. By writing a covered put option, the Fund, in exchange for the premium, accepts the risk of decline in the market value of the underlying security or foreign currency below the exercise price. After writing a put option, the Fund may incur a loss equal to the difference between the exercise price of the option and the sum of the market value of the underlying security plus the premium received from the sale of the option. A call option may be covered by the call writer's owning the underlying security throughout the option period. A call option may also be covered by the call writer's maintaining liquid assets valued at greater than the exercise price of the call written, in a segregated account with its custodian. The Fund may purchase call and put options on its portfolio securities. The Fund may purchase call options to protect against an increase in the price of the security it anticipates purchasing. The Fund may purchase put options on its securities to protect against a decline in the value of the security or to close out covered written put positions. The Fund may also purchase options to seek to enhance returns. Risks may arise from an imperfect correlation between the change in market value of the securities held by the Fund and the prices of options relating to the securities purchased or sold by the Fund and from the possible lack of a liquid secondary market for an option. The maximum exposure to loss for any purchased option is limited to the premium initially paid for the option. (D) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 7.) (E) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (F) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. www.MAINSTAYfunds.com 21 NOTES TO FINANCIAL STATEMENTS (CONTINUED) (G) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Income from payment-in-kind securities is recorded daily based on the effective interest method of accrual. The investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (H) FOREIGN CURRENCY TRANSACTIONS. The books and records of the Fund are kept in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean between the buying and selling rates last quoted by any major U.S. bank at the following dates: (i) market value of investment securities, other assets and liabilities -- at the valuation date, (ii) purchases and sales of investment securities, income and expenses -- at the date of such transactions. The assets and liabilities are presented at the exchange rates and market values at the close of the period. The realized and unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. Net realized gain (loss) on foreign currency transactions represents net gains and losses on foreign currency forward contracts, net currency gains or losses realized as a result of differences between the amounts of securities sale proceeds or purchase cost, dividends, interest and withholding taxes as recorded on the Fund's books, and the U.S. dollar equivalent amount actually received or paid. Net currency gains or losses from valuing such foreign currency denominated assets and liabilities, other than investments, are reflected in unrealized foreign exchange gains or losses at period end exchange rates. (I) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (J) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (K) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.72% on assets up to $500 million, 0.67% on assets from $500 million to $1 billion and 0.62% on assets in excess of $1 billion. NYLIM has voluntarily agreed to waive its management fee by 0.05% to 0.67% on assets up to $500 million, 0.62% on assets from $500 million to $1 billion and 0.57% on assets in excess of $1 billion. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total 22 MainStay Convertible Fund operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.20% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $213,955 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM had agreed to voluntarily reimburse the expenses of the Fund so that total annual fund operating expenses would not exceed on an annualized basis 1.20% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $3,836,288, and waived its fees and/or reimbursed expenses in the amount of $935,148. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager paid the Subadvisor a monthly fee of 0.36% of the Fund's average daily net assets on assets up to $500 million, 0.335% on assets from $500 million to $1 billion and 0.31% on assets in excess of $1 billion. To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $47,455 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $2,503, $259,488 and $3,639, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $1,654,776. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. (F) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $13,858 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services www.MAINSTAYfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) provided to the Fund by the Manager amounted to $80,193 for the year ended October 31, 2005. NOTE 4 -- CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, State Street Bank and Trust Company acted as custodian for the Fund. NOTE 5 -- FEDERAL INCOME TAX: As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> UNDISTRIBUTED ACCUMULATED TOTAL ORDINARY CAPITAL AND UNREALIZED ACCUMULATED INCOME OTHER LOSSES APPRECIATION LOSS $406,763 $(46,602,275) $20,794,514 $(25,400,998) </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to wash sale deferrals. At October 31, 2005, for federal income tax purposes, capital loss carryforwards of $46,602,275 were available as shown in the table below, to the extent provided by the regulations to offset future realized gains of the Fund through the years indicated. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to shareholders. <Table> <Caption> CAPITAL LOSS AMOUNT AVAILABLE THROUGH (000'S) 2010 $41,599 2011 5,003 - ----------------------------------------------- $46,602 - ----------------------------------------------- </Table> The Fund utilized $38,995,498 of capital loss carryforwards during the year ended October 31, 2005.

Pursuant to Rule 2a-7, securities purchased with collateral received are valued at amortized cost. NOTE 8 -- LINE OF CREDIT: The Fund and certain affiliated funds maintain a line of credit of $160,000,000 with a syndicate of banks in order to secure a source of funds for temporary purposes to meet unanticipated or excessive shareholder redemption requests. The funds pay a commitment fee, at an annual rate of .075% of the average commitment amount, regardless of usage, to The Bank of New York, which acts as agent to the syndicate. Such commitment fees are allocated among the funds based upon net assets and other factors. Interest on any revolving credit loan is charged based upon the Federal Funds Advances rate. There were no borrowings on the line of credit during the year ended October 31, 2005.

NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay Convertible Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 25 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Convertible Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Convertible Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 26 MainStay Convertible Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's underperformance over certain recent periods, a short-term period of significant underperformance in 2003 that has adversely affected the Fund's relative performance over various time periods, recent change of personnel on the portfolio management team serving the Fund, and recent improvements in the Fund's performance resulting in the Fund's having improved comparative performance against a group of Funds concluded by the Trustees to be peers of the Fund. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. 30 MainStay Convertible Fund The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees noted that the Fund's contractual management fee had been reduced in accordance with the terms of the breakpoint schedule applicable to the Fund. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 31 FEDERAL INCOME TAX INFORMATION (UNAUDITED) The dividends paid by the Fund during the fiscal year ended October 31, 2005, should be multiplied by 100% to arrive at the amount eligible for qualified dividend income and 100% for the corporate dividends received deduction.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ CHRISTOPHER O. BLUNT Christopher O.

Total returns reflect change in share price, reinvestment of dividend and capital-gain distributions, and maximum applicable sales charges explained in this paragraph. The graphs assume an initial investment of $10,000 and reflect the deduction of all sales charges that would have applied for the period of investment. Class A shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1 fee of .25%. Class B shares are sold with no initial sales charge, are subject to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are subject to a CDSC of 1% if redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales charge or CDSC, have no annual 12b-1 fee, and are generally available to corporate and institutional investors with a minimum initial investment of $5 million. Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. The fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD 10/31/05 PERIOD CLASS A SHARES(1) $1,000.00 $1,069.30 $ 7.20 $1,018.10 $ 7.02 - ------------------------------------------------------------------------------------------------------------------- CLASS B SHARES(1) $1,000.00 $1,066.15 $11.09 $1,014.35 $10.81 - ------------------------------------------------------------------------------------------------------------------- CLASS C SHARES(1) $1,000.00 $1,066.15 $11.09 $1,014.35 $10.81 - ------------------------------------------------------------------------------------------------------------------- CLASS I SHARES(1) $1,000.00 $1,072.60 $ 3.97 $1,021.20 $ 3.87 - ------------------------------------------------------------------------------------------------------------------- </Table> 1.

The Fund normally invest at least 80% of its assets in common stocks. We seek to identify companies that are considered to have a high probability of outperforming the S&P 500(R) Index(1) over the following six to twelve months. Our underlying stock-selection process is based on a quantitative process that ranks stocks based on traditional value measures, earnings quality, and technical factors. These stocks are then generally held in larger or smaller proportions based on their relative attractiveness. On occasion, trading strategies that seek to realize returns over shorter periods may be employed. The Fund normally invests in common stocks of well-established U.S. companies, primarily those with large capitalizations. The Fund is managed with a core orientation (including both growth and value equities). We use a bottom-up approach that assesses stocks based on their individual strengths, rather than focusing on the underlying sectors or industries of those stocks or on general economic trends. We may sell a security if we no longer believe it will contribute to meeting the investment objective of the Fund. WHAT WERE THE MAJOR FACTORS AFFECTING THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? For the 12 months ended October 31, 2005, all broadly watched equity indices provided positive performance. Mid- and small-capitalization stocks generally outperformed their large-cap counterparts. The market favored value stocks over growth stocks at all capitalization levels. Despite wide fluctuations in crude-oil prices, instability in many regions of the world, and the devastation caused by hurricanes Katrina and Rita, the U.S. stock market posted significant gains during the 12 months ended October 31, 2005. The Federal Open Market Committee continued to raise its target for the federal funds rate, with eight 25-basis-point increases during the reporting period. (A basis point is one-hundredth of a percentage point.) At the end of October 2005, the target rate stood at 3.75%, its highest level in more than four years. Among the considerations that influenced the gradual tightening policy were mounting inflationary pressures, low unemployment, an upward path of record energy prices, and growing labor costs. WERE THERE ANY CHANGES IN THE FUND'S POSITIONING OR MANAGEMENT DURING THE REPORTING PERIOD? MainStay Common Stock Fund uses a quantitative model. There were minor adjustments to the model during the reporting period. We added a "change in shares outstanding" factor and an "industry relative price to cash flow" factor. The Fund has maintained a fairly neutral positioning during the reporting period, with a projected beta very close to one.(2) HOW WAS THE FUND ALLOCATED RELATIVE TO THE S&P 500(R) INDEX DURING THE REPORTING PERIOD? During the 12 months ended October 31, 2005, the Fund was overweighted relative to the S&P 500(R) Index in the utilities, energy, information technology, financials, and telecommunication services sectors. During the reporting period, the Fund was under-weighted relative to the Index in the consumer staples, industrials, consumer discretionary, materials, and health care sectors. WHICH SECTORS AND INDIVIDUAL STOCKS MADE THE MOST SUBSTANTIAL POSITIVE CONTRIBUTIONS TO THE FUND'S PERFORMANCE DURING THE 12-MONTH REPORTING PERIOD? The Fund's five strongest-performing sectors were energy, financials, health care, utilities, and consumer staples. Among individual stocks, the strongest contributors to the Fund's performance were ConocoPhillips, an integrated global energy company that continued to post high earnings; UnitedHealth Group, a health care service provider that increased earnings, lowered costs, and achieved higher membership; and the parent company of Philip Morris and Kraft Foods, Altria Group, which benefited from optimism over favorable court rulings. WHICH SECTORS AND INDIVIDUAL STOCKS DETRACTED FROM THE FUND'S PERFORMANCE? The Fund's five weakest-performing sectors during the 12-month reporting period were telecommunication services, consumer discretionary, materials, industrials, and information technology. 1. See footnote on page 4 for more information on the S&P 500(R) Index. 2. Beta is a measure of the volatility of a stock in relation to the market as a whole. The S&P 500(R) Index has a beta of one. Stocks with a higher beta tend to be more volatile than the market. Stocks with a lower beta tend to rise and fall more slowly than the market. www.MAINSTAYfunds.com 7 Among individual stocks, the weakest contributors to the Fund's performance were Pfizer, a pharmaceutical company whose shares fell on negative news about Celebrex; Fannie Mae, a government-sponsored mortgage provider that experienced accounting problems; and Verizon Communications, a communication services provider. Verizon Communications' shares declined when competitor Sprint merged with Nextel Communications. WERE THERE ANY SIGNIFICANT EQUITY PURCHASES OR SALES DURING THE REPORTING PERIOD? The Fund uses a quantitative model whose major inputs include price-to-cash-flow, earnings trends, earnings quality, and price trends. A combination of these factors may be used in determining additions to the Fund's portfolio. In some instances, stocks are included in the Fund for diversification and risk-control purposes even if they score poorly in the model. From November 2004 through July 2005, the Fund established a position in Vertex Pharmaceuticals, a biotechnology company whose stock advanced when the company announced that it would be streamlining its developmental pipeline. SanDisk Corp. was purchased for the Fund in August 2005. The company, which designs, develops, and markets flash-storage card products used in consumer electronics, benefited from continued strong demand. From December 2004 through June 2005, the Fund established a position in Murphy Oil. This holding company, which engages in the exploration, production, refining, and marketing of oil and gas, nearly doubled its profit because of higher energy prices. We sold the Fund's entire positions in Delta Air Lines, Toys "R" Us, and Storage Technology during the reporting period. Toys "R" Us and Storage Technology were sold at a profit, but Delta Air Lines was sold at a loss. Delta Air Lines struggled with increased competition and higher fuel prices. Toys "R" Us, which sells toys, children's apparel, and baby products, had its stock bought out by a private equity partnership. Storage Technology, a leading storage company, was sold when our quantitative model indicated that its shares had become overvalued.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Common Stock Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Distribution of Class A shares and Class B shares commenced on June 1, 1998. Class C shares were initially offered on September 1, 1998. Distribution of Class I shares commenced on December 28, 2004. Class A shares are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class I shares are not subject to sales charge. Class A shares, Class B shares, Class C shares and Class I shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions. Each class of shares other than Class I shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. The Fund's investment objective is to seek long-term growth of capital, with income as a secondary consideration. NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See note 7) (C) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. 22 MainStay Common Stock Fund The following table discloses the current period reclassification between undistributed net investment income, accumulated net realized loss on investments and additional paid-in capital arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> ACCUMULATED UNDISTRIBUTED NET REALIZED NET INVESTMENT LOSS ON ADDITIONAL INCOME INVESTMENTS PAID-IN-CAPITAL $ (380) $ 4,770 $ (4,390) </Table> The reclassifications for the Fund are primarily due to the fact that net operating losses cannot be carried forward for federal income tax purposes and real estate investment trusts investments. (E) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (F) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (G) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (H) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. The Fund is advised by the Manager directly, without a Subadvisor. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.70% on assets up to $500 million and 0.65% on assets in excess of $500 million. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.30% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $124,534 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, the Manager had agreed to reimburse the expenses of the Fund so that total operating expenses would not exceed, on an annualized basis, 1.38% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. Prior to December 1, 2004, the Manager voluntarily agreed to reimburse the expenses of the Fund so that operating expenses would not exceed on an annualized basis 1.65%, 2.40%, and 2.40% of average daily net assets of the Class A, Class B, and Class C shares, respectively. For the year ended October 31, 2005, the Manager earned fees from the www.MAINSTAYfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) Fund in the amount of $904,732, and waived its fees and/or reimbursed expenses in the amount of $435,191. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, other than Class I shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $13,578 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $1,495, $77,935 and $579, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $537,805. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. (F) CAPITAL. At October 31, 2005, New York Life and its affiliates held shares of Class A with a net value of $12,313,969. This represents 34.3% of Class A shares net assets and 7.7% of the Funds total net assets at period end. (G) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $3,537 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $39,591 for the year ended October 31, 2005. NOTE 4 -- CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, The Bank of New York acted as custodian for the Fund. NOTE 5 -- FEDERAL INCOME TAX: As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> ACCUMULATED TOTAL ORDINARY CAPITAL AND UNREALIZED ACCUMULATED INCOME OTHER LOSSES APPRECIATION LOSS $539,396 $(13,718,729) $ 6,543,345 $(6,635,988) </Table> At October 31, 2005, for federal income tax purposes, capital loss carryforwards of $13,718,729 were available as shown in the table below, to the extent provided by the regulations to offset future realized gains of the Fund through the years indicated. To the extent that these loss 24 MainStay Common Stock Fund carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to shareholders. <Table> <Caption> CAPITAL LOSS AMOUNTS AVAILABLE THROUGH (000'S) 2010 $11,364 2011 2,355 ------------------------------------------- $13,719 ------------------------------------------- </Table> The Fund utilized $5,887,435 of capital loss carryforward during the year ended October 31, 2005.

NOTE 10 -- OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to agreements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay Common Stock Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 25 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Common Stock Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Common Stock Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 26 MainStay Common Stock Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of the Agreement, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non- Interested Trustees to discuss the Board's consideration of the approval of the Agreement, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager. The Trustees reviewed the services that the Manager has provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the day-to-day management of the portfolio and the selection and supervision of portfolio managers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Trustees considered, among other things, the Manager's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager and certain other service providers. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager were such that, in the context of the Board's overall review of various factors, the Management Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's recent performance that was slightly better than mid-range of funds determined to be comparable to the Fund and the Fund's underperformance over a longer time period relative to the average of a grouping of funds having similar investment objectives. The Trustees considered the cost to the Manager of the Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached 30 MainStay Common Stock Fund the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationship between the Manager and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between them. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreement. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreement. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreement, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of this Agreement was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 31 PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that New York Life Investment Management LLC ("NYLIM") uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by calling 1-800-MAINSTAY (1-800-624-6782); (ii) by visiting the Fund's website at www.mainstayfunds.com; or (iii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ Christopher O. Blunt Christopher O.

Total returns reflect change in share price, reinvestment of dividend and capital-gain distributions, and maximum applicable sales charges explained in this paragraph. The graphs assume an initial investment of $10,000 and reflect the deduction of all sales charges that would have applied for the period of investment. Class A shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1 fee of .25%. Class B shares are sold with no initial sales charge, are subject to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are subject to a CDSC of 1% if redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%. Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. The fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. From inception (6/1/98) through 8/31/98, performance for Class C shares (first offered 9/1/98) includes the historical performance of Class B shares adjusted to reflect the applicable CDSC for Class C shares.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT VALUE ENDING ACCOUNT (BASED ON VALUE (BASED HYPOTHETICAL BEGINNING ON ACTUAL EXPENSES 5% RETURN EXPENSES ACCOUNT RETURNS AND PAID AND ACTUAL PAID VALUE EXPENSES) DURING EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,094.05 $ 8.71 $1,016.75 $ 8.39 - -------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,090.30 $12.64 $1,013.00 $12.18 - -------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,090.30 $12.64 $1,013.00 $12.18 - -------------------------------------------------------------------------------------------------------------------- </Table> 1.

Spelman of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 80% of its assets in companies with market capitalizations at the time of investment comparable to those of companies in the Russell 2000(R) Index.(1) We select investments according to the economic environment, the attractiveness of particular markets, and the financial condition and competitiveness of individual companies. In implementing this strategy, we look for securities of companies with above-average revenue and earnings-per-share growth, participation in growing markets, potential for positive earnings surprises, and strong management. Ideally, the companies will have high levels of ownership by insiders. We may also invest in companies that we believe are attractive because of special factors, such as new management, new products, changes in consumer demand, or changes in the economy. We may sell a stock if the stock's earnings growth rate decelerates, if its valuation is deemed too high in relation to its growth rate or its peer group, or if we no longer believe that the security will help the Fund meet its investment objective. WHAT MAJOR FACTORS INFLUENCED STOCK-MARKET PERFORMANCE DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? Among the most significant factors that influenced the equity markets during the reporting period were Federal Reserve interest-rate hikes, high energy prices, rising inflation, and the apparent slowdown in the rate of corporate earnings growth and economic advancement. An influx of hurricanes in the late summer and early fall took a toll not only on the Gulf states but also on the overall market. WHAT SECTORS HAD THE GREATEST IMPACT ON THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING PERIOD? The Fund's performance was helped most by favor-able stock selection in the consumer discretionary sector. The Fund's holdings in this sector outperformed related stocks in the Russell 2000(R) Growth Index.(2) An overweighted position in the energy sector and an underweighted position in the information technology sector also helped the Fund's results. The Fund's stock selection in the information technology and health care sectors, however, detracted from performance. For the 12 months ended October 31, 2005, we maintained the Fund's overweighted position in the consumer discretionary sector. Our decision to do so had a positive effect on the Fund's performance. Our decision to increase the Fund's weighting among energy stocks also strengthened the Fund's returns. WHAT WERE SOME OF THE FUND'S STOCK-SPECIFIC SUCCESS STORIES? Cal Dive International was the strongest positive contributor to the Fund's performance. With operations in the Gulf of Mexico, this energy services company benefited from higher energy prices and continued strong demand. Coldwater Creek, originally a catalog and mail order house, advanced on rapid expansion of the company's retail store chain. Shares of Arch Coal, a company that mines, processes, and markets low-sulfur coal, rose steadily throughout the reporting period because of higher energy prices and growing global demand. Ryland Group is a homebuilder that benefited from continued strong demand and industry consolidation. Shares of Sierra Health Services, a Las Vegas-based managed health care organization, rose with commercial enrollment-driven earnings growth because of the company's dominant market presence in Nevada. WHICH STOCKS DETRACTED FROM THE FUND'S RESULTS? Several of the Fund's holdings failed to meet our expectations. Sigmatel is a semiconductor company that supplies memory chips for Apple iPod Shuffles. The company's stock dropped sharply in October 2005 because of faster-than-expected product transition. PETCO Animal Supplies--a retailer of pet food, supplies, and services--was hurt by reduced store traffic and by a shift in marketing strategy that failed to generate anticipated sales. Trex manufactures and distributes wood/plastic composite products primarily for residential and commercial decking and railing. Trex had a rough 12-month period because of lower-than-expected volume, which stemmed from excess inventory among dealers and from significant increases in the price of raw materials. Bradley Pharmaceuticals, a specialty phar- Stocks of small companies may be subject to higher price volatility, significantly lower trading volumes, and greater spreads between bid and ask prices than stocks of larger companies. Small companies may be more vulnerable to adverse business or market devel- opments than mid- or large-capitalization companies. The Fund may experience a portfolio turnover rate of over 100% and may generate short-term capital gains which are taxable. 1. See footnote on page 5 for information on the Russell 2000(R) Index. 2. See footnote on page 5 for information on the Russell 2000(R) Growth Index. 8 MainStay Small Cap Growth Fund maceutical company, suffered a sharp stock-price decline when the company announced that its accounting practices would be investigated by the Securities and Exchange Commission. Innovative Solutions & Support--a company that designs, manufactures, and sells flight-information computers, flat-panel displays, and monitoring systems--reported disappointing first-quarter 2005 results. We sold the Fund's positions in Sigmatel, Trex, and Bradley Pharmaceuticals during the reporting period. WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD? Since energy prices remained high, we added Grant Prideco to the Fund. The company produces oil-field drill pipe and other products and services used in drilling for oil and gas. We also established a Fund position in James River Coal, which engages in mining, processing, and selling coal in eastern Kentucky. We initiated a Fund position in Electronic Boutiques Holdings, which recently merged with GameStop to form a leading global retailer of video-game and entertainment software. We believe that the merger may help the company enter new international markets and compete more effectively in the highly competitive U.S. video-game industry. In the consumer discretionary sector, we added Children's Place, a retailer of children's apparel and accessories that recently acquired the Disney Store chain. Earnings at The Children's Place Retail Stores are expected to benefit from acquisition-related synergies and cost reductions. We also established a Fund position in Jos. A. Bank Clothiers, which designs, retails, and markets men's tailored and casual clothing and men's accessories in the United States. WHICH STOCKS DID THE FUND SELL DURING THE REPORTING PERIOD? In addition to the sales we've already mentioned, the Fund eliminated its holdings in Bluegreen and Corinthian Colleges during the reporting period. Bluegreen offers timeshare vacation properties and builds residential communities. The company experienced a sharp stock-price correction when it reported disappointing earnings because of higher-than-expected costs and lower-than-expected sales. We sold the Fund's position in Corinthian Colleges because of disappointing earnings results and concerns about government investigations into the industry's marketing practices. DID THE FUND CHANGE ITS SECTOR WEIGHTINGS DURING THE REPORTING PERIOD? From October 31, 2004, to October 31, 2005, we substantially increased the Fund's weighting in the energy sector. We also increased the Fund's weighting among industrial stocks. During the reporting period, the Fund decreased its weightings in the consumer discretionary, health care, and information technology sectors. HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD? As of October 31, 2005, the Fund was overweighted relative to the Russell 2000(R) Growth Index in the consumer discretionary, energy, and industrial sectors. On the same date, the Fund held under-weighted positions in the consumer staples, health care, materials, and information technology sectors. At the end of the period, the Fund had no holdings in the telecommunication services or utilities sectors.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Small Cap Growth Fund (the "Fund"), a diversified fund. The Fund currently offers three classes of shares. Distribution of Class A shares and Class B shares commenced on June 1, 1998. Class C shares were initially offered on September 1, 1998. Class A shares are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class A shares, Class B and Class C shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions except that the Class B shares and Class C shares are subject to higher distribution fee rates. Each class of shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. The Fund's investment objective is to seek long term-capital appreciation by investing primarily in securities of small-cap companies. Small-capitalization companies may be more volatile in price and have significantly lower trading volumes than companies with larger capitalizations. They may be more vulnerable to adverse business or market developments than larger-capitalization companies. NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (see Note 7.) (C) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between accumulated net investment loss and 18 MainStay Small Cap Growth Fund additional paid-in-capital arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> ADDITIONAL NET INVESTMENT LOSS PAID-IN-CAPITAL $3,979,978 $(3,979,978) </Table> The reclassification for the Fund is due to the fact that net operating losses cannot be carried forward for federal income tax purposes. (E) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (F) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (G) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (H) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 1.00% on assets up to $1.0 billion and 0.95% on assets in excess of $1.0 billion. NYLIM agrees to voluntarily waive its management fee by 0.15% to 0.85%. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.48% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. There were no amounts available for recoupment at October 31, 2005. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM agreed to voluntarily reimburse the expenses of the Fund so that the total operating expenses would not exceed on an annualized basis 1.70% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the manager earned fees from the Fund in the amount of $2,545,742 and waived its fees and/or reimbursed expenses in the amount of $731,987. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of 0.50% of the average daily net assets of the Fund. To the extent the www.MAINSTAYfunds.com 19 NOTES TO FINANCIAL STATEMENTS (CONTINUED) Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $42,687 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $5,693, $245,716 and $855, respectively, for the year ended October 31, 2005.

NOTE 5 -- FEDERAL INCOME TAX: As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> ACCUMULATED CAPITAL UNREALIZED TOTAL ACCUMULATED AND OTHER LOSSES APPRECIATION LOSS $(151,508,855) $50,129,652 $(101,379,203) </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to wash sales deferrals. At October 31, 2005, for federal income tax purposes, capital loss carryforwards of $151,508,855 were available as shown in the table below, to the extent provided by the regulations to offset future realized gains of the Fund through the years indicated. To the extent that these loss carryforwards are used to offset future capital gains, it is 20 MainStay Small Cap Growth Fund probable that the capital gains so offset will not be distributed to shareholders. <Table> <Caption> CAPITAL LOSS AMOUNTS AVAILABLE THROUGH (000'S) 2009 $108,332 2010 40,252 2011 2,925 --------------------------------------------- $151,509 --------------------------------------------- </Table> The Fund utilized $27,664,156 capital loss carryforwards during the year ended October 31, 2005.

The Funds pay a commitment fee, at an annual rate of .075% of the average commitment amount, regardless of usage, to The Bank of New York, which acts as agent to the syndicate. Such commitment fees are allocated among the Funds based upon net assets and other factors. Interest on any revolving credit loan is charged based upon the Federal Funds Advances rate. There were no borrowings on the line of credit during the year ended October 31, 2005.

NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay Small Cap Growth Fund was $38,000. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 21 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Small Cap Growth ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Small Cap Growth Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 22 MainStay Small Cap Growth Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's underperformance when compared over several time periods with funds concluded by Trustees to be peers of the Fund. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual 26 MainStay Small Cap Growth Fund breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund were among the highest of the series of the Trust, and also that transfer agency fees of a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 27 PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that New York Life Investment Management LLC ("NYLIM") uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by calling 1-800-MAINSTAY (1-800-624-6782); (ii) by visiting the Fund's website at www.mainstayfunds.com; or (iii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ CHRISTOPHER O. BLUNT Christopher O.

Total returns reflect change in share price, reinvestment of dividend and capital-gain distributions, and max-imum applicable sales charges explained in this paragraph. The graphs assume an initial investment of $10,000 and reflect the deduction of all sales charges that would have applied for the period of investment. Class A shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1 fee of .25%. Class B shares are sold with no initial sales charge, are subject to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are subject to a CDSC of 1% if redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales charge or CDSC, have no annual 12b-1 fee, and are generally available to corporate and institutional investors with a minimum initial investment of $5 million. Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. The fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. From inception (6/1/98) through 8/31/98, performance for Class C shares (first offered 9/1/98) includes the historical performance of Class B shares adjusted to reflect the applicable CDSC for Class C shares. From inception through 2/15/05, performance of Class I shares (first offered 2/16/05) includes the historical performance of Class A shares adjusted to reflect the applicable sales charge (or CDSC) and fees and expenses for Class I shares.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD 10/31/05 PERIOD CLASS A SHARES(1) $1,000.00 $1,036.35 $ 7.55 $1,017.65 $ 7.48 - ----------------------------------------------------------------------------------------------------------------------- CLASS B SHARES(1) $1,000.00 $1,033.20 $11.38 $1,013.90 $11.27 - ----------------------------------------------------------------------------------------------------------------------- CLASS C SHARES(1) $1,000.00 $1,033.20 $11.38 $1,013.90 $11.27 - ----------------------------------------------------------------------------------------------------------------------- CLASS I SHARES(1) $1,000.00 $1,040.45 $ 5.30 $1,019.85 $ 5.24 - ----------------------------------------------------------------------------------------------------------------------- </Table> 1.

The Fund normally invests at least 80% of its assets in companies with market capitalizations at the time of investment comparable to companies in the Russell 2000(R) Value Index(1) and invests primarily in common stocks and securities convertible into common stock. In implementing this strategy, we use an investment selection process that focuses on stocks that meet three criteria: inexpensive valuations, free cash flow, and multiple sources of potential growth or earnings. We look for stocks that are inexpensive relative to the Russell benchmark, their peer group, or historical valuations. We take a long-term approach to investing and rely primarily on our proprietary fundamental research. The portfolio is constructed using a bottom-up stock selection process. Stocks will be sold when they meet our price objective or when we believe there is a negative change in the fundamental performance of the issuer. WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? The stock market reacted to concerns about the potential impact of higher energy prices and rising interest rates on consumer spending. According to Russell data, mid-capitalization stocks showed the strongest performance during the 12-month reporting period, followed by small-caps, and then large-cap stocks. From a style perspective, value stocks outperformed growth stocks at all capitalization levels. In the Russell 2000(R) Value Index, the consumer discretionary sector sold off more than 4% during the third calendar quarter of 2005 and continued to be weak as the market reacted to fears of a slowdown in consumer spending, exacerbated by hurricanes Katrina and Rita. WHAT FACTORS HAD A SIGNIFICANT IMPACT ON THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? Excluding all sales charges, all share classes of the Fund underperformed the Russell 2000(R) Value Index during the 12-month reporting period. The Fund's overweighted positions in consumer discretionary and information technology, the two worst-performing sectors in the Index, were partly to blame. During the reporting period, we increased the Fund's position in Graftech International to place it among the Fund's largest holdings. Since this stock showed particularly weak performance, however, it detracted from the Fund's results during the reporting period. WHICH OF THE FUND'S HOLDINGS WERE STRONG PERFORMERS DURING THE REPORTING PERIOD? Parker Drilling, an oil and gas contract drilling company, provided strong performance during the period, reflecting positive fundamentals in the energy sector. The company also sold several of its assets and used the proceeds to improve its balance sheet, putting the company on a much stronger financial footing. Global Industries, an offshore oil and gas construction company, was also a strong performer during the period, benefiting from trends similar to those that helped Parker Drilling. Trammel Crow, a real estate management company, was also a strong performer for the 12-month reporting period. The company benefited from a recovery in the nonresidential real estate market, which had been weak despite the strength in residential home building. THQ, a developer of interactive entertainment software, performed well because of improved earnings from the company's proprietary software releases. Priority Healthcare, a specialty pharmaceutical distributor, also contributed positively to performance during the reporting period, advancing on an acquisition bid from a rival company. WHICH STOCKS UNDERPERFORMED? As mentioned, Graftech International, a manufacturer of graphite electrodes sold to the steel industry, was a significant detractor during the 12-month reporting period. The company's share price plunged on dis-appointing volume and earnings guidance for 2005. Because we believe the company's long-term fundamentals remain positive, we used the sell-off as an opportunity to add to the Fund's position. Cost Plus, a specialty retailer of casual home furnishings and entertaining products, declined during the 12-month reporting period, but we initiated the Fund's position in May 2005 to take advantage of weak sales trends and a management transition. We believe that the company may benefit from several potentially positive catalysts, including a new management, easier same-store sales comparisons, and high unit-volume growth. Stocks of small companies may be subject to higher price volatility, significantly lower trading volumes, and greater spreads between bid and ask prices than stocks of larger companies. Small companies may be more vulnerable to adverse business or market devel- opments than mid- or large-capitalization companies. 1. See footnote on page 5 for more information on the Russell 2000(R) Index. 8 MainStay Small Cap Value Fund Hooper Holmes, which provides risk assessment services primarily to the life insurance industry, was down during the reporting period. The company suffered from weakness in the life insurance market and from the board's decision to replace both the CEO and CFO after several years of poor results. Jo-Ann Stores, a fabric and craft materials retailer, fell during the reporting period, on weaker-than-expected same-store sales and general concerns about consumer spending. We took advantage of the weakness to add to the Fund's position because we believe the stock represents a good long-term investment. Hancock Fabrics, a fabric retailer, also declined during the reporting period, although the Fund sold its position in June 2005. WERE THERE ANY SIGNIFICANT EQUITY PURCHASES DURING THE REPORTING PERIOD? In addition to Graftech International, Cost Plus, and Jo-Ann Stores, which we previously discussed, the Fund initiated a position in Zoran in March 2005. The company sells semiconductor chips for DVDs, digital phones, high-definition digital televisions, and other growing end markets. We believe Zoran is successfully diversifying its revenue stream away from just DVDs, a move that could fuel significant earnings growth over the next several years. Carmike Cinemas, which owns and operates theaters in small- and mid-sized markets, was a new holding added to the Fund in July 2005. While the stock was weak from our purchase through the end of the reporting period because of lower-than-expected earnings and a weak box office, we believe that management is focused on cutting costs and increasing cash flows. In December 2004, we initiated a position in Kadant, a company that manufactures and markets equipment and accessories for paper production. We believe that the company's earnings may improve as a result a recent divestiture, efforts to restructure the company's European manufacturing plant, and improving end-market demand. WHAT SECURITIES DID YOU SELL DURING THE REPORTING PERIOD? During the reporting period, we eliminated several stocks, including Wabtec, Post Properties, Pharmaceutical Product Development, and Steiner Leisure. Each of these holdings reached the predetermined price targets we had set for the stock. Wabtec benefited from internal cost cutting and a recovery in demand and was eliminated in October 2005. Multifamily apartment company Post Properties was sold in June 2005, while recovering demand and a restructured property portfolio helped push the company's stock price higher. Pharmaceutical Product Development, a drug-discovery and services company, was eliminated from the Fund in March 2005. The company had posted several quarters of better-than-expected earnings growth, and the stock's valuation had become very expensive relative to other investment opportunities. In June 2005, we sold the Fund's holdings in Steiner Leisure, a company that manages spas for cruise ships and resorts. Steiner Leisure had successfully increased earnings and market share and had used free cash flow to improve the company's balance sheet and initiate a share buyback program. DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD? The Fund's sector weightings result primarily from our bottom-up security selection process, which focuses on attractive valuations. Industry and security movements may also affect weightings. During the 12-month period, the Fund's exposure to the health care sector declined. This drop reflected profit-taking in certain stocks, as well as takeovers in Priority Healthcare and Renal Care Group. The Fund's health care holdings made a positive contribution to the Fund's returns during reporting period. The Fund's weighting in the consumer discretionary sector rose substantially. The increase reflected the sector's underperformance and our subsequent ability to find long-term investment opportunities within the sector. Adding to the consumer discretionary weighting hurt the Fund's relative return during the reporting period. As long-term investors, however, we believe the sector may offer significant opportunities over the long term.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Small Cap Value Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Distribution of Class A shares and Class B shares commenced on June 1, 1998. Class C shares were initially offered on September 1, 1998. Distribution of Class I shares commenced on February 16, 2005. Class A shares are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class I shares are not subject to sales charge. Distribution of Class I shares commenced on January 1, 2004. Class A, Class B, Class C and Class I shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions. Each class of shares other than Class I shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution or service fee. The Fund's investment objective is to seek long-term capital appreciation by investing primarily in securities of small-cap companies. Small-capitalization companies may be more volatile in price and have significantly lower trading volumes than companies with larger capitalizations. They may be more vulnerable to adverse business or market developments than large-capitalization companies. NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices are normally taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 7). (C) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis 18 MainStay Small Cap Value Fund treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between accumulated net investment loss, accumulated net realized gain on investments, and additional paid-in-capital arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> ACCUMULATED NET ACCUMULATED NET REALIZED GAIN ON ADDITIONAL INVESTMENT LOSS INVESTMENTS PAID-IN-CAPITAL $1,036,304 $(925,790) $(110,514) - -------------------------------------------------------------- </Table> The reclassification for the Fund is primarily attributable net operating losses that offset undistributed net short-term securities gains for federal income tax purposes, real estate investment trusts and distributions paid in connection with the redemption of Fund shares. (E) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (F) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (G) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (H) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.85% on assets up to $1.0 billion and 0.80% on assets in excess of $1.0 billion. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.90% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after July 1, 2004, NYLIM voluntarily agreed to waive a portion of its management fee in excess of 0.60% of the Fund's average daily net assets. The Manager also agreed to voluntarily reimburse the expenses of the Fund so that the total operating expenses would not exceed on an annualized basis 1.90 of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the manager earned www.MAINSTAYfunds.com 19 NOTES TO FINANCIAL STATEMENTS (CONTINUED) fees from the Fund in the amount of $1,287,432 and waived its fees and/or reimbursed expenses in the amount of $378,656. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee of one-half of the management fee, net of management fee waivers, expense limitations and reimbursements.. To the extent the manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, other than Class I shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $34,828 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $918, $62,234 and $2,222, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund, for the year ended October 31, 2005, amounted to $633,692. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings.

NOTE 10 -- OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay Small Cap Value Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. www.MAINSTAYfunds.com 21 NOTES TO FINANCIAL STATEMENTS (CONTINUED) In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. 22 MainStay Small Cap Value Fund REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Small Cap Value ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Small Cap Value Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 www.MAINSTAYfunds.com 23 TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared to multiple comparison groups, including with reference to information provided by outside data providers and analyzed with the assistance of a third party consultant. The Trustees referred to discussions held during periodic meetings of the Performance Committee of the Board to discuss investment performance-related matters with the Manager. In reviewing the Fund's performance, the Board recognized the underperformance of the Fund over various time periods relative to funds concluded by Trustees to be peers of the Fund but acknowledged its recent approval of the selection of the Subadvisor as a new subadviser for the Fund. The Trustees noted that, as the Subadvisor had not yet provided subadvisory services to the Fund for a meaningful period of time, they would monitor and evaluate such services over time. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in www.MAINSTAYfunds.com 27 particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. 28 MainStay Small Cap Value Fund FEDERAL INCOME TAX INFORMATION (UNAUDITED) The Fund is required by the Internal Revenue Code to advise shareholders within 60 days of the Fund's fiscal year end (October 31, 2005) as to the federal tax status of dividends paid by the Fund during such fiscal year.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ Christopher O. Blunt Christopher O.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT VALUE ENDING ACCOUNT (BASED ON VALUE (BASED HYPOTHETICAL BEGINNING ON ACTUAL EXPENSES 5% RETURN EXPENSES ACCOUNT RETURNS AND PAID AND ACTUAL PAID VALUE EXPENSES) DURING EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,049.20 $3.82 $1,021.30 $3.77 - -------------------------------------------------------------------------------------------------------------------- </Table> 1.

Ok of New York Life Investment Management LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 80% of its total assets in stocks contained in the S&P 500(R) Index(1) in the same proportion, to the extent feasible, as they are represented in the Index. In implementing this strategy, we use statistical techniques to determine which stocks are to be purchased or sold to replicate the S&P 500(R) Index to the extent feasible. The Fund's investments also include S&P 500(R) Index futures, which are used for cash management purposes. WHAT WERE THE MAJOR FACTORS THAT AFFECTED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? For the 12 months ended October 31, 2005, all broadly watched equity indices provided positive performance. Mid- and small-capitalization stocks generally outperformed their large-cap counterparts. The market favored value stocks over growth stocks at all capitalization levels. Despite wide fluctuations in crude-oil prices, instability in many regions of the world, and the devastation caused by hurricanes Katrina and Rita, the U.S. stock market posted significant gains during the 12-month period ended October 31, 2005. The Federal Open Market Committee continued to raise its target for the federal funds rate, with eight 25-basis-point increases during the reporting period. (A basis point is one-hundredth of a percentage point.) At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Among the considerations that influenced the gradual tightening policy were mounting inflationary pressures, low unemployment, an upward path of record energy prices, and growing labor costs. WHAT WERE THE BEST-PERFORMING INDUSTRIES IN THE S&P 500(R) INDEX DURING THE REPORTING PERIOD? From a total-return perspective, tobacco was the best-performing industry for the 12 months ended October 31, 2005. Other top-performing industries from a total-return perspective included health care providers & services, energy equipment & services, construction & engineering, and independent power producers & energy traders. On the basis of impact, which takes weightings and total returns both into account, the industry that made the strongest contribution to the performance of the Index was oil, gas & consumable fuels. The second-strongest contributor was health care providers & services, followed by insurance, capital markets, and tobacco. WHICH INDUSTRIES WERE THE WORST PERFORMERS? On the basis of total returns alone, the worst-performing industry in the Index for the 12-month reporting period was automobiles. The second-worst total return came from Internet & catalog retail, followed by leisure equipment & products, auto components, and thrifts & mortgage finance. For the 12 months ended October 31, 2005, media was the industry with the greatest negative impact on Index performance when weightings and total returns were both considered. Pharmaceuticals was next, followed by thrifts & mortgage finance, automobiles, and Internet & catalog retail. WHICH INDIVIDUAL STOCKS WERE THE BEST PERFORMERS DURING THE REPORTING PERIOD? For the 12 months ended October 31, 2005, the S&P 500(R) Index stock with the highest total return was Valero Energy. Express Scripts had the second-best total return, followed by NVIDIA, Humana, and Apple Computer. Each of these top performers more than doubled in price during the reporting period. The five stocks with the greatest positive impact on the performance of the S&P 500(R) Index all had higher weightings and lower total returns. On the basis of impact, which takes weightings and total returns both into account, the strongest positive contributor to the performance of the Index for the 12-month reporting period was Altria Group. The second-best contributor was ExxonMobil, followed by ConocoPhillips, UnitedHealth Group, and Hewlett-Packard. WHICH STOCKS WERE THE WEAKEST PERFORMERS DURING THE REPORTING PERIOD? For the 12-months ended October 31, 2005, the S&P 500(R) Index stock with the worst total return was Sanmina-SCI. Other particularly weak performers This Fund was closed to new purchases as of January 1, 2002. Index funds generally seek to reflect the performance of an index or an allocation among indices, unlike other funds, whose objectives may, in some cases, involve seeking to outperform an index or other benchmark. The Fund may invest in derivatives, which may increase the volatility of the Fund's net asset value and may result in a loss to the Fund. 1. See footnote on page 4 for more information on the S&P 500(R) Index. www.MAINSTAYfunds.com 7 included Unisys, Gateway, Lexmark International, and Dana. On the basis of impact, which takes weightings and total returns both into account, Pfizer made the greatest negative contribution to the performance of the Index for the 12-month reporting period. Wal-Mart Stores was next, followed by Fannie Mae, Verizon Communications, and International Business Machines. WERE ANY CHANGES MADE TO THE FUND OR TO THE INDEX DURING THE PERIOD? The Fund seeks to track the performance and weightings of stocks in the S&P 500(R) Index. The Index itself, however, may change from time to time as companies merge, divest units, add to their market capitalization, or face financial difficulties. Standard & Poor's may also occasionally adjust the Index to better reflect the companies that it believes are most representative of the makeup of the U.S. economy. During the 12 months ended October 31, 2005, there were 20 additions to the Index and 20 deletions from it. Among the additions were well-known companies such as Compass Bancshares, Vornado Realty Trust, Tyson Foods, Public Storage, and Lennar. Among the deletions were familiar names such as Deluxe, Winn-Dixie Stores, Delta Air Lines, Unocal, and Delphi. When Sears, Roebuck merged with Kmart, the stock was deleted from the Index but simultaneously reappeared as Sears Holdings. Adolf Coors merged with Molson and was deleted when Molson Coors Brewing was added to the Index. Peoplesoft was deleted from the Index because the company was acquired by Oracle; Nextel Communications was deleted when the company was acquired by Sprint; and Wellpoint Health Networks was deleted when it was acquired by Anthem.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Equity Index Fund (the "Fund"). The Board of Trustees of the Trust approved the closure of the Fund to new share purchases effective January 1, 2002. Existing shareholders may continue to maintain share positions held in the Fund, elect or continue to reinvest distributions, and NYLIFE LLC will continue to honor the unconditional guarantee associated with the Fund (see Note 10). The Fund's investment objective is to seek to provide investment results that correspond to the total return performance (and reflect reinvestment of dividends) of publicly traded common stocks represented by the Standard & Poor's 500 Composite Stock Price Index. The Fund is "non-diversified," which means that it may invest a greater percentage of its assets than diversified funds in a particular issuer. This may make it more susceptible than diversified funds to risks associated with an individual issuer, and to single economic, political or regulatory occurrences. NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Futures contracts are valued at the last posted settlement price on the market where such futures are principally traded. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) FUTURES CONTRACTS. A futures contract is an agreement to purchase or sell a specified quantity of an underlying instrument at a specified future date and price, or to make or receive a cash payment based on the value of a securities index. During the period the futures contract is open, changes in the value of the contract are recognized as unrealized gains or losses by "marking to market" such contract on a daily basis to reflect the market value of the contract at the end of each day's trading. The Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as "variation margin". When the futures contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. The Fund invests in stock index futures contracts to gain full exposure to changes in stock market prices to fulfill its investment objective. The use of futures contracts involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statement of Assets and Liabilities. The contract or notional amounts and variation margin reflect the extent of the Fund's involvement in open futures positions. Risks arise from the possible imperfect correlation in movements in the price of futures contracts, interest rates and the underlying hedged assets, and the possible inability of counterparties to meet the terms of their contracts. However, the Fund's activities in futures contracts are conducted through regulated exchanges which minimize counterparty credit risks. (C) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (D) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of 22 MainStay Equity Index Fund the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. (E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current period reclassification between accumulated undistributed net investment income, accumulated net realized loss on investments and additional paid-in-capital arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> ACCUMULATED UNDISTRIBUTED NET REALIZED NET INVESTMENT LOSS ON ADDITIONAL INCOME INVESTMENTS PAID-IN-CAPITAL $ (12,906) $ 12,907 $ (1) </Table> The reclassification for the Fund is due to real estate investment trust distributions. The Fund declared a dividend of $0.4138 per share which was paid on December 21, 2004, and also underwent a reverse share split on that day. The reverse share split rate was 0.9897 per share outstanding calculated on fund shares outstanding immediately after reinvestment of dividends. Certain amounts in the Financial Highlights and Notes to Financial Statements (see Note 9) have been adjusted to reflect the cumulative effects of this reverse stock split, those that occurred in each of the periods presented, and the reverse stock split that occurred in December 2005. (See Note 12) (F) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. (G) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (H) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (I) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life, serves as the Fund's Manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. The Fund is advised by the Manager directly, without a Subadvisor. The Trust, on behalf of the Fund, paid the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets. Effective as of August 1, 2004, NYLIM had voluntarily agreed to waive its management fee by 0.25% to 0.25% of the Fund's average net assets. Effective August 1, 2005, the contractual management fee for the Fund was reduced to 0.25% of assets up to $1.0 billion; 0.225% from $1.0 billion to $3.0 billion; and 0.20% in excess of $3.0 billion. In addition, effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 0.65% of the average daily net assets of the Fund. The Manager, www.MAINSTAYfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $209,184 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005, NYLIM agreed to voluntarily reimburse the expenses of the Fund so that the total operating expenses would not exceed on an annualized basis 0.80% of the average daily net assets of the Fund. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $2,974,068 and waived and/or reimbursed expenses in the amount of $1,696,218. (B) DISTRIBUTION FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund has adopted a distribution plan (the "Plan") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Plan, the Distributor receives payments from the Fund at an annual rate of 0.25% of the Fund's average daily net assets, which is an expense of the Fund for distribution or service activities as designated by the Distributor. The Plan provides that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $1,045,865. (D) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. (E) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $15,300 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $86,148 for the year ended October 31, 2005. NOTE 4 -- CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, The Bank of New York acted as custodian for the Fund. NOTE 5 -- FEDERAL INCOME TAX: At November 30, 2004, the Fund's year end for federal income tax purposes, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> UNDISTRIBUTED ACCUMULATED TOTAL ORDINARY CAPITAL UNREALIZED ACCUMULATED INCOME LOSSES APPRECIATION GAIN $ 6,496,775 $(122,345,938) $159,582,678 $43,733,515 </Table> The difference between book-basis and tax-basis unrealized depreciation is due to wash sale deferrals, and mark-to-market of futures contracts. At November 30, 2004, for federal income tax purposes, capital loss carryforwards of $122,345,938 were available as shown in the table below, to the extent provided by the regulations to offset future realized gains of the Fund through the years indicated. To the extent that these loss carryforwards are used to offset future capital gains, it is 24 MainStay Equity Index Fund probable that the capital gains so offset will not be distributed to shareholders. <Table> <Caption> CAPITAL LOSS AMOUNTS AVAILABLE THROUGH (000'S) 2010........ $ 89,854 2011........ 29,198 2012........ 3,294 ------------------------------------------- $122,346 ------------------------------------------- </Table> The tax character of distributions paid during the years ended October 31, 2005 and October 31, 2004, shown in the Statement of Changes in Net Assets, were as follows: <Table> <Caption> 2005 2004 Distributions paid from: Ordinary Income $6,540,173 $2,344,657 - ---------------------------------------------------------- </Table> NOTE 6 -- PURCHASES AND SALES OF SECURITIES (IN 000'S): During the year ended October 31, 2005, purchases and sales of securities, other than short-term securities, were $31,642, and $108,074, respectively. NOTE 7 -- PORTFOLIO SECURITIES LOANED: As of October 31, 2005, the Fund had securities on loan with an aggregate market value of $43,491,422. The Fund received $44,991,834 in cash as collateral for securities on loan which was used to purchase highly liquid short-term investments in accordance with the Fund's securities lending procedures. Pursuant to Rule 2a-7, securities purchased with collateral received are valued at amortized cost. NOTE 8 -- LINE OF CREDIT: The Fund and certain affiliated funds maintain a line of credit of $160,000,000 with a syndicate of banks in order to secure a source of funds for temporary purposes to meet unanticipated or excessive shareholder redemption requests. The funds pay a commitment fee, at an annual rate of .075% of the average commitment amount, regardless of usage, to The Bank of New York, which acts as agent to the syndicate. Such commitment fees are allocated among the funds based upon net assets and other factors. Interest on any revolving credit loan is charged based upon the Federal Funds Advances rate. There were no borrowings on the line of credit during the year ended October 31, 2005. NOTE 9 -- CAPITAL SHARE TRANSACTIONS (IN 000'S): <Table> <Caption> YEAR ENDED YEAR ENDED OCTOBER 31, OCTOBER 31, 2005 2004 Shares sold(a) 175 6 - ---------------------------------------------------------- Shares issued in reinvestment of distributions(a) --(b) 61 - ---------------------------------------------------------- 175 67 - ---------------------------------------------------------- Shares redeemed(a) (2,583) (2,427) - ---------------------------------------------------------- Net decrease(a) (2,408) (2,360) - ---------------------------------------------------------- </Table> (a) Adjusted to reflect the cumulative effects of the reverse stock split in the period, as well as the reverse stock split on December 21, 2005. (See Note 2(E) and 12) (b) Less than 1,000 shares. NOTE 10 -- GUARANTEE: NYLIFE LLC ("NYLIFE"), a wholly-owned subsidiary of New York Life, will guarantee unconditionally and irrevocably pursuant to a Guaranty Agreement between NYLIFE and the Fund (the "Guarantee") that if, on the business day immediately after ten years from the date of purchase (the "Guarantee Date"), the net asset value ("NAV") of a Fund share plus the value of all dividends and distributions paid, including cumulative reinvested dividends and distributions attributable to such share paid during that ten-year period ("Guaranteed Share"), is less than the price initially paid for the Fund share ("Guaranteed Amount"), NYLIFE will pay shareholders an amount equal to the difference between the Guaranteed Amount for each such Guaranteed Share outstanding and held by shareholders as of share and the net asset value of each such of the close of business on the Guarantee Date. For the services that NYLIM and its affiliates provide to the Fund, they receive the fees described in the prospectus. Neither NYLIM nor its affiliates receive a separate fee for providing the Guarantee, although the Guarantee has been considered in connection with the annual renewal of the management fee. (see Note 3.) NOTE 11 -- OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by www.MAINSTAYfunds.com 25 NOTES TO FINANCIAL STATEMENTS (CONTINUED) clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay Equity Index Fund was $516,000. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the Fund and the fees and expenses of the fund as well as the related guarantee disclosure to Fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. NOTE 12 -- SUBSEQUENT EVENT: Subsequent to October 31, 2005, the Fund declared a dividend of 0.5112 per share which was paid on December 21, 2005, and also underwent a reverse share split on that day. The reverse share split rate was 0.9880 per share outstanding calculated on fund shares outstanding immediately after reinvestment of dividends. Certain amounts in the Statement of Assets and Liabilities, Financial Highlights, and Notes to Financial Statements (see Note 9) have been adjusted to reflect the effects of this subsequent reverse stock split. 26 MainStay Equity Index Fund REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Equity Index Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Equity Index Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 www.MAINSTAYfunds.com 27 TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of the Agreement, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non- Interested Trustees to discuss the Board's consideration of the approval of the Agreement, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager. The Trustees reviewed the services that the Manager has provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the day-to-day management of the portfolio and the selection and supervision of portfolio managers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, managing reverse stock splits, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Trustees considered, among other things, the Manager's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager and certain other service providers. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. The Trustees acknowledged the guarantee feature and the role of an affiliate of the Manager with regard to the guarantee. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager were such that, in the context of the Board's overall review of various factors, the Management Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's success in providing investment results that corresponded to the total return performance of stocks representing the S&P 500 Index. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to reduce the Fund's management fee and limit the Fund's net expenses to a certain level with respect to the Fund. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees, in considering economies of scale, noted that the Fund is closed to new share purchases and, for that reason, can increase its asset size only through capital appreciation. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from www.MAINSTAYfunds.com 31 time to time. They noted the implementation of a contractual management fee breakpoint that would reduce the contractual management fee to which the Fund is subject were the Fund to reach the applicable asset level. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationship between the Manager and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between them. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreement. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreement. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreement, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of this Agreement was in the best interests of the Fund and its shareholders. 32 MainStay Equity Index Fund FEDERAL INCOME TAX INFORMATION (UNAUDITED) The dividends paid by the Fund during the fiscal year ended October 31, 2005, should be multiplied by 100% to arrive at the amount eligible for qualified dividend income and 100% for the corporate dividends received deduction.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. /s/ CHRISTOPHER O. BLUNT Christopher O.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,083.45 $ 7.09 $1,018.25 $ 6.87 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,079.80 $11.01 $1,014.50 $10.66 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,079.80 $11.01 $1,014.50 $10.66 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,085.55 $ 4.99 $1,020.25 $ 4.84 - --------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,085.05 $ 5.52 $1,019.75 $ 5.35 - --------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,084.20 $ 6.83 $1,018.50 $ 6.61 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Gillott of Jennison Associates LLC CAN YOU DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 65% of its total assets in equity-type securities, including common stocks, as well as securities convertible into, or exchangeable for, common stocks. The Fund employs two subadvisors, Markston International and Jennison Associates, with complementary investment processes and styles. In pursuing the Fund's investment objective, each subadvisor seeks to identify securities that are out of favor but have a catalyst that the subadvisor believes will lead to improved performance. WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? Markston International: There were several economic crosscurrents during the 12 months ending October 31, 2005. Higher energy prices were among the most notable. Markston's share of the Fund was overweighted in energy. Jennison Associates: Mixed economic data left the equity markets unsettled during the reporting period. Equities started with strength, but began to retrace their gains as oil prices climbed to record highs. Elevated energy prices, higher inflation, and rising interest rates were among investors' chief concerns. Even so, equity indices moved higher across the board during the 12 months ended October 31, 2005. From a sector perspective, utilities and energy led the S&P 500(R) Index,(1) while more economically sensitive sectors trailed. WHAT FACTORS MOST SIGNIFICANTLY AFFECTED FUND PERFORMANCE DURING THE REPORTING PERIOD? Markston International: We believe that our time and labor intensive approach, which attempts to find what we term "alpha generators"(2) in the securities we consider for investment, helped the portion of the Fund we manage to more than double the performance of the S&P 500(R) Index for the reporting period. We typically look for the presence of three of the following six "alpha generators": insider buying, stock repurchase by the company, meaningful restructuring, new management, companies that operate in consolidating industries, and the presence of tax loss carryforwards. Jennison Associates: Our portion of the Fund's portfolio outperformed the S&P 500(R) Index during the reporting period. Energy sector holdings made the greatest positive contribution to performance in our portion of the Fund's portfolio. Our weighting and stock-selection decisions helped energy holdings in our portion of the Fund outpace related stocks in the S&P 500(R) Index. With growth in global demand, difficulties in reserve-replacement, and setbacks in production growth, oil services companies were able to raise prices as equipment and crews approached full utilization. Integrated oil companies and larger exploration & production companies actually became less price-sensitive and more willing to pay high prices to secure crews and equipment for longer periods. Effective stock selection in the financials, information technology, and health care sectors also bolstered both absolute and relative results in our portion of the Fund's portfolio. Significant exposure to the materials sector added to absolute returns, but individual stock disappointments led our materials holdings to lag the broad equity market. Modest exposure to utilities detracted from relative performance as well. Only the telecommunications services sector hurt our portion of the Fund's performance on both an absolute and relative basis. WHAT WERE SOME OF THE FUND'S STRONG PERFORMERS DURING THE REPORTING PERIOD? Markston International: Our portion of the Fund benefited from its position in Genentech, a leading biotechnology firm. Genen-tech's stock appreciated substantially after the company reported that its primary cancer drug, Avastin, was effective in fighting small-cell lung cancer. Genentech developed Avastin without a partner, so it has maintained the bulk of the profits from the drug. Mid-capitalization companies are generally less established and their stocks may be more volatile and less liquid than the securities of larger companies. Stocks of small companies may be subject to higher price volatility, significantly lower trading volumes, and greater spreads between bid and ask prices than stocks of larger companies. Small companies may be more vulnerable to adverse business or market developments than mid- or large-capitalization companies. Funds that invest in bonds are subject to credit, inflation, and interest-rate risk and can lose principal value when interest rates rise. Issuers of convertible securities may not be as financially strong as those issuing securities with higher credit ratings and may be more vulnerable to changes in the economy. If an issuer stops making interest payments, principal payments, or both on its convertible securities, these securities may become worthless and the Fund could lose its entire investment in them. 1. See footnote on page 4 for more information about the S&P 500(R) Index. 2. Alpha is a measure of excess return adjusted for volatility. www.MAINSTAYfunds.com 7 Devon Energy appreciated during the reporting period as the price of oil increased. Devon Energy is a frugally run oil and gas independent that has consistently increased reserves per share, has insider buying by management, a substantial stock-repurchase program, and a policy of restructuring periodically to upgrade the company's properties. Part of our position came from other stocks we owned that were acquired by Devon Energy. Another strong performer for our portion of the Fund was Cerner, a software and systems provider to the hospital industry. The company initially attracted us because of insider buying, management changes, and restructuring activity. Cerner has shown strong execution, posting above-average growth while successfully furthering its penetration into the U.K. and French markets. American Commercial Lines is one of the larger commercial barge operators in the United States. The stock advanced dramatically when low-cost barge transportation came into demand as oil prices rose and the number of coal shipments by barge increased. During the reporting period, American Commercial Lines emerged from a substantial reorganization under the leadership of new management. Chesapeake Energy, the second-largest independent producer of natural gas in the United States, saw its stock appreciate during the reporting period because of the enormous rise in natural gas prices. Since Chesapeake Energy has no assets in the Gulf of Mexico, the company was not affected by hurricanes Katrina and Rita. Jennison Associates: Our holdings in oil services companies performed particularly well, including Todco, National Oilwell Varco, and BJ Services. These stocks benefited from oil-related trends that we've previously discussed. Pharmacy benefits manager Medco Health Solutions was also among the strongest contributors to performance in our portion of the Fund's portfolio. The company performed well on better-than-expected new-business sign-ups and positive prospects for administering Medicare drug programs in 2006. We reduced our position in the stock, however, when it approached our target valuation. Health management organization Cigna's shares rose when investors gained confidence in the company's ongoing restructuring efforts. We sold our position in Cigna toward the end of the reporting period, taking profits. UnumProvident, a leading provider of disability and specialty risk insurance, also strengthened results in our portion of the Fund's portfolio. The company continued to execute its disability-business turnaround successfully by focusing on the strong middle market and completing the repricing of UnumProvident's unprofitable national-account business. We trimmed the Fund's position in the stock, even though we continued to feel that it was attractively valued. WHAT STOCKS UNDERPERFORMED DURING THE REPORTING PERIOD? Markston International: The Fund's position in Eyetech Pharmaceuticals, an emerging biotech company that pursues unmet eye-related medical needs, detracted from results. Eyetech developed an FDA-approved drug, Macugen, to treat wet macular degeneration. The company's stock declined after interim data from Genentech suggested that a competing Genentech compound, if approved, could give Macugen serious competition. Eyetech was recently acquired by OSI Pharmaceuticals. Another poor performer for our portion of the Fund was Gemstar-TV Guide International. The company completed several deals that gave customers access to the company's intellectual property in return for cash and various industrial arrangements. Unfortunately, the company has faced more challenges than it has managed to meet. We reduced the Fund's stake in the holding. S1, a small software supplier to companies offering financial services, saw its shares decline when the company had trouble meeting its growth projections. During the reporting period, S1's Board of Directors changed CEOs, a nonstrategic asset was sold, and the company materially cut costs. At current prices, we think S1 represents value. Symbol Technologies, a major participant in the bar code and emerging radio-frequency ID industry, detracted from results. The company has put allegations of a previous management team's misconduct to rest. Current management has cut costs to improve profitability, and we think the company is on the mend. Our position in Boston Scientific, a medical-device company, underperformed when competitor Johnson & Johnson gained market share in the drug-eluting coronary stent market. Boston Scientific appears to have stabilized at a price/earnings multiple that is at a discount to most other medical-device suppliers. Jennison Associates: Generic drug manufacturer Andrx detracted from results in our portion of the Fund's portfolio. The company was set back when the Food and Drug Administration placed the company on "official action indicated" status, which effectively put all of 8 MainStay MAP Fund the com-pany's new drug applications on hold. Andrx also lost its chief financial officer and general counsel. We trimmed the Fund's position in Andrx, and have continued to monitor the company's situation closely. GrafTech International, which makes graphite and carbon products used in steel and aluminum production, lost volume when the company decided to raise prices to reflect higher costs for raw materials. We eliminated the stock from our portion of the Fund on concerns about steel prices and GrafTech's financial leverage. We sold electronic-equipment company Symbol Technologies at a loss, when the closely timed departures of the CEO and the CFO raised the company's risk profile. Shares of aluminum giant Alcoa slipped when the company announced layoffs, plant closings, and consolidations scheduled during the next several months. Aluminum stocks also came under pressure from concerns that Chinese production growth and export potential might upset an otherwise healthy global supply-and-demand balance. Radio One, a media company, saw its share price decline when the company's revenue trends came in, below the market's expectations. Investments in improving content have also added to expenses, but we remain optimistic about pricing potential later in the year. WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD? Markston International: We either established new positions or added to the Fund's existing positions in several companies. American Express appears to be in a higher-growth mode. Morgan Stanley has new management, which we believe will benefit the company. Amgen appears to be on the verge of some new drug approvals. Union Pacific is getting a new CEO, is enjoying improved pricing, and appears to have enhanced productivity. Pogo Producing restructured to move its operations to North America. W.R. Berkley's exploitation of market niches has helped it post a return-on-equity ratio of more than 20%. Covanta Holding, formerly Danielson Holding, has emerged as the market leader in waste-to-electricity generation. The company has a large tax loss carryforward and generates substantial cash flow. On balance, these holdings helped relative performance in our portion of the Fund's portfolio during the reporting period. Jennison Associates: We continue to build our portion of the Fund's portfolio one stock at a time, using a bottom-up, research-intensive process. During the reporting period, we established and then added to a position in insurance company American International Group because of the stock's attractive valuation. We also initiated a position in Royal Bank of Scotland, a top-10 global bank with its several well-known retail franchises, including Citizen's Bank and Charter One Financial in the United States and Nat West and Royal Bank of Scotland in the U.K. Greenwich Capital Markets gives Royal Bank of Scotland a strong capital-markets franchise in the United States. We established a position in BJ Services, a global oil service company that specializes in pressure pumping and is particularly exposed to the North American natural gas market. We believe the company should continue to benefit from the supply-and-demand imbalance in oil and natural gas. We established a position in capital markets firm Charles Schwab early in the Fund's fiscal year and have increased the position throughout the reporting period. We also increased our position in Kroger, the largest pure grocery chain in the United States. WHAT SECURITIES DID YOUR PORTION OF THE FUND'S PORTFOLIO SELL DURING THE REPORTING PERIOD? Markston International: We can and do sell stocks for a variety of reasons, including controlling portfolio volatility. During the reporting period, we reduced our positions in Tyco International and Cell Therapeutics, among others, at attractive prices. Jennison Associates: On the basis of our stringent risk/reward criteria, we eliminated our position in Companhia Vale do Rio Doce, one of the world's largest iron-ore producers. We also exited our position in Cigna. We eliminated our position in Great Lakes Chemical when the company's share price rose on news of a friendly acquisition by Crompton Corporation. In our portion of the Fund, we also sold positions in Cooper Cameron, a leading subsea equipment manufacturer, and in National Oilwell Varco, an oil rig equipment manufacturer. In each of these cases, we were able to take profits for the Fund. DID THE FUND CHANGE ITS INDUSTRY GROUP WEIGHTINGS? Markston International: Our portion of the Fund began the reporting period with overweighted positions relative to the S&P 500(R) Index in energy, financials, industrials, materials, and utilities and with underweighted positions in consumer discretionary, consumer staples, information www.MAINSTAYfunds.com 9 technology, and telecommunications services. We had a relatively equal weighting to the Index in health care. During the reporting period, we slightly increased the Fund's exposure to the financials sector and modestly decreased the Fund's allocation to information technology. Jennison Associates: Any weighting changes in our portion of the Fund's portfolio are a consequence of our bottom-up stock-selection process and do not reflect a "sector bet" on the part of our management team. During the reporting period, the risk/reward discipline that guides our portion of the Fund's portfolio led us to take profits in many strong performers, increase our weightings in health care and utilities, and decrease our weightings in basic materials and energy. We trimmed the Fund's exposure to materials, because of inventory increases that resulted from slower economic growth during the first half of 2005. In the energy sector, we continued to hold oil services companies, where earnings continued to accelerate, and we eliminated positions in the oil & gas exploration & production and integrated oil & gas subindustries. We continued to limit exposure to banks in our portion of the Fund's portfolio in an attempt to remain insulated from the effects of a flattening yield curve. HOW DO THE FUND'S WEIGHTINGS DIFFER FROM THOSE OF ITS BENCHMARK? Markston International: As of October 31, 2005, the portion of the Fund we manage was underweighted relative to the S&P 500(R) Index in the consumer discretionary, consumer staples, information technology, and telecommunications services sectors. At the same time, the Fund held overweighted positions relative to the Index in the utilities, materials, industrials, financials, and energy sectors and a relatively neutral position in health care. Our portion of the Fund's portfolio also held a sizable position in cash. Jennison Associates: As of October 31, 2005, our portion of the Fund's portfolio was overweighted relative to the S&P 500(R) Index in the consumer discretionary and materials sectors and underweighted relative to the Index in the consumer staples, information technology, and industrials sectors.

NOTES TO FINANCIAL STATEMENTS NOTE 1 -- ORGANIZATION AND BUSINESS: The MainStay Funds (the "Trust") was organized on January 9, 1986 as a Massachusetts business trust. The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay MAP Fund (the "Fund"), a diversified fund. The Fund currently offers six classes of shares. Class A shares, Class B shares, Class C shares, Class I shares, Class R1 shares and Class R2 shares. Distribution of Class A shares, Class B shares, Class C shares and Class I shares commenced on June 9, 1999. Distribution of Class R1 shares and Class R2 shares commenced on January 2, 2004. Class A shares are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class I, Class R1 and Class R2 shares are not subject to a sales charge. The six classes of shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation, and other rights and conditions except that Class B shares and Class C shares are subject to higher distribution fee rates than Class A shares and Class R2 shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares and Class R1 shares are not subject to a distribution or service fee. Class R1 and Class R2 shares are authorized to pay to New York Life Investment Management LLC, its affiliates, or third-party service providers, as compensation for services rendered to shareholders of Class R1 or Class R2 shares, a shareholder service fee. The Fund's investment objective is to seek long-term appreciation of capital. The Fund also seeks to earn income, but this is a secondary objective. The Fund invests in foreign securities which carry certain risks that are in addition to the usual risks inherent in domestic instruments. These risks include those resulting from currency fluctuations, future adverse political and economic developments and possible imposition of currency exchange blockages or other foreign governmental laws or restrictions. These risks are likely to be greater in emerging markets than in developed markets. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country, industry or region. NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Debt securities are valued at prices supplied by a pricing agent or brokers selected by the Fund's Manager, whose prices reflect broker/dealer supplied valuations and electronic data processing techniques, if such prices are deemed by the Fund's Manager to be representative of market values, at the regular close of business of the New York Stock Exchange. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. At October 31, 2005, the Fund did not hold securities that were valued in such a manner. Certain events may occur between the time that foreign markets close, on which securities held by the Fund principally trade, and the time at which the Fund's NAV is calculated. These events may include, but are not limited to, situations relating to a single issue in a market sector, significant fluctuations in U.S. or foreign markets, natural disasters, armed conflicts, governmental actions or other developments not tied directly to the securities markets. Should the Manager or Subadvisor conclude that such events may have effected the accuracy of the last price reported on the local foreign market, the Manager or Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of the local price to reflect the impact on the price of such securities as a result of such events. (B) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all www.MAINSTAYfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 7). (C) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current period reclassification between undistributed net investment income, accumulated net realized gain on investments and additional paid-in capital arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> ACCUMULATED UNDISTRIBUTED NET REALIZED NET INVESTMENT GAIN ON ADDITIONAL INCOME INVESTMENTS PAID-IN-CAPITAL $ (21,795) $ 55,322 $ (33,527) </Table> The reclassification for the Fund is primarily due to the fact that net operating losses cannot be carried forward for federal income tax purposes, foreign currency gain (loss), real estate investment trusts investments and distributions paid in connection with the redemption of Fund shares. (E) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Income from payment-in-kind securities is recorded daily based on the effective interest method of accrual. The investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (F) FOREIGN CURRENCY TRANSACTIONS. The books and records of the Fund are kept in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean between the buying and selling rates last quoted by any major U.S. bank at the following dates: (i) market value of investment securities, other assets and liabilities -- at the valuation date, (ii) purchases and sales of investment securities, income and expenses -- at the date of such transactions. The assets and liabilities are presented at the exchange rates and market values at the close of the period. The realized and unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. Net realized gain (loss) on foreign currency transactions represents net gains and losses on foreign currency forward contracts, net currency gains or losses realized as a result of differences between the amounts of securities sale proceeds or purchase cost, dividends, interest and withholding taxes as recorded on the Fund's books, and the U.S. dollar equivalent amount actually received or paid. Net currency gains or losses from valuing such foreign currency denominated assets and liabilities, other than investments, are reflected in unrealized foreign exchange gains or losses at period end exchange rates. (G) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. 24 MainStay MAP Fund (H) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (I) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. Markston International LLC and Jennison Associates LLC (the "Subadvisors") will each manage a portion of the Fund's assets, as designated by NYLIM from time to time, subject to the oversight of NYLIM. Each Subadvisor is responsible for the day-to-day portfolio management of the Fund with respect to its allocated portion of the Fund's assets. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.75% on assets up to $1.0 billion and 0.70% on assets in excess of $1.0 billion. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.35% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $222,593 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005, the Manager had agreed to voluntarily reimburse the expenses of the Fund so that total annual fund operating expenses do not exceed on an annualized basis 1.35% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $8,674,774 and waived its fees and/or reimbursed expenses in the amount of $237,690. Pursuant to the terms of a Sub-Advisory Agreement between the Manager and the Subadvisors, the Manager pays the Subadvisors a monthly fee at an annual rate of the Fund's average daily net assets of 0.45% on assets up to $250 million, 0.40% on assets from $250 million to $500 million and 0.35% on assets in excess of $500 million. (B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to Class A, Class B, Class C, and Class R2 shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A and Class R2 Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A and Class R2 shares, which is an expense of the Class A and Class R2 shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. The Fund has adopted a shareholder services plan with respect to Class R1 and Class R2 shares.

As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay MAP Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the 'Board of Trustees' review of this matter, and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 27 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay MAP Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay MAP Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 28 MainStay MAP Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisors. The Trustees reviewed the services that the Manager and Subadvisors have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisors' services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees discussed with the Manager the proportion of the portfolio managed by each Subadvisor and each Subadvisor's capacity with respect to managing assets of the Fund. The Trustees considered, among other things, the Manager's and Subadvisors' management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisors' practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisors and certain other service providers, as well as each Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisors were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's competitive performance over several periods and particularly over five years. In addition, the Board considered each Subadvisor's performance and complementary investment processes and styles, and the Manager's oversight role, including with respect to allocating the Fund's assets between the portfolios managed by the two Subadvisors. The Trustees reviewed information about such options as adding a new subadviser in the event that the Fund's assets significantly increase in size or applying to the SEC for an exemption to allow the hiring and replacement of multiple subadvisers without the requirement of obtaining shareholder approval for each such hiring and replacement. There is no assurance that the Fund will seek such an exemption or, if sought, that the SEC would grant an order providing such an exemption. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The 32 MainStay MAP Fund Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees, in reviewing economies of scale, noted the substantial growth of the Fund over the past five years. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized if the Fund continues to grow, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees noted that the Fund's contractual management fee had been reduced in accordance with the terms of the breakpoint schedule applicable to the Fund. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisors and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 33 FEDERAL INCOME TAX INFORMATION (UNAUDITED) The Fund is required by the Internal Revenue Code to advise shareholders within 60 days of the Fund's fiscal year and (October 31, 2005) as to the federal tax status of dividends paid by the Fund during such fiscal year.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /S/ CHRISTOPHER O. BLUNT Christopher O.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $ 999.15 $5.29 $1,019.75 $5.35 - --------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $ 995.40 $9.05 $1,016.00 $9.15 - --------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $ 995.40 $9.05 $1,016.00 $9.15 - --------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,001.65 $3.38 $1,021.65 $3.41 - --------------------------------------------------------------------------------------------------------------------- </Table> 1.

Saxon of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 80% of its assets in U.S. government securities. It may invest up to 20% of its assets in mortgage-related and asset-backed securities or other securities that are not U.S. government securities. In implementing this strategy, we use a combined approach to investing. We analyze economic trends as well as factors pertinent to particular issuers and securities. The Fund's principal investments include U.S. Treasury bills, notes, and bonds, Ginnie Mae certificates, and other U.S. government securities representing ownership interests in mortgage pools, such as securities issued by Fannie Mae and Freddie Mac. We may sell securities when the condition of the economy, meaningful changes in an issuer's condition, or other factors suggest that the securities will no longer contribute to the Fund's ability to meet its investment objective. WHAT ECONOMIC FORCES AFFECTED THE BOND MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? Debate over the lasting effects of higher energy costs continued, with aggregate demand and inflation among the key concerns. Noting that "higher energy and other costs have the potential to add to inflation pressures," the Federal Open Market Committee raised the targeted federal funds rate to 3.75% on September 20, 2005. The move was the FOMC's eighth 25-basis-point increase during the 12-month reporting period. (A basis point is one-hundredth of a percentage point.) Since rebuilding activity following hurricanes Katrina and Rita may stimulate the economy, money-market futures anticipate that additional interest-rate hikes may be needed to keep inflation in check. HOW DID THE TREASURY YIELD CURVE CHANGE DURING THE REPORTING PERIOD? From October 29, 2004, to October 31, 2005, the two-year Treasury yield advanced 183 basis points (from 2.56% to 4.38%). Over the same period, five-year Treasury yields increased 116 basis points (from 3.29% to 4.45%) and 10-year Treasury yields rose 53 basis points (from 4.03% to 4.56%). On the other hand, 30-year Treasury yields declined four basis points (from 4.79% to 4.75%).(1) With Federal Reserve action pushing short-term interest rates higher and foreign-investors supporting long bonds, the yield curve flattened substantially. The spread between two-year and 30-year Treasurys narrowed 186 basis points. HOW DID YOU POSITION THE PORTFOLIO ACROSS THE VARIOUS BOND SECTORS AVAILABLE TO THE FUND? At the end of October 2005, the Fund held approximately 5% of its net assets in Treasurys, 27% in agency debentures, 55% in residential mortgage-backed securities issued by government-sponsored and government-related enterprises, 5% in asset-backed securities, 6% in commercial mortgage-backed securities, and 2% in investment-grade corporate bonds. During the reporting period, we favored securitized products for their relatively high credit quality, liquidity, and incremental yield. We diversified the Fund's holdings in securitized issues across residential mortgage-backed, commercial mortgage-backed, and asset-backed securities. DID YOU MAKE ANY CHANGES TO THE FUND'S ALLOCATION DURING THE REPORTING PERIOD? In prior periods, we used prepayments from mortgage-backed and asset-backed bonds to repurchase securities in the respective sectors. During the reporting period, we had two reasons for deciding to use such proceeds in other ways. First, we wanted to pare back the Fund's exposure to the mortgage-backed and asset-backed sectors because we felt that interest-rate volatility might increase during the Federal Reserve's tightening cycle. Second, we wanted to offset some of the Fund's extension risk--or the risk that rising rates might cause mortgage-backed securities to extend the Fund's duration. During the reporting period, we also added incremental yield by rotating 10% of the Fund's assets from Treasurys into agency debentures. We added a 1% position in Treasury Inflation-Protected Securities (TIPS) to capitalize on higher energy prices. To trim credit risk, we shifted 1% of the Fund's net assets out of corporate bonds and asset-backed securities into commercial mortgage-backed securities. Investments in the Fund are not guaranteed, even though some of the Fund's investments are guaranteed by the U.S. government or its agencies or instrumentalities. The Fund may invest in derivatives, which may increase the volatility of the Fund's net asset value and may result in a loss to the Fund. The Fund may experience a portfolio turnover rate of over 100% and may generate short- term capital gains which are taxable. Funds that invest in bonds are subject to interest-rate risk and can lose principal value when interest rates rise and may generate short-term capital gains. 1. Source: Bloomberg-Historical yield curve data. Rounding may affect results. www.MAINSTAYfunds.com 7 HOW DID YOU MANAGE THE FUND'S DURATION DURING THE REPORTING PERIOD? We try to maintain the Fund's average duration between 3.75 and 4.25 years, a range that we believe is consistent with the Fund's peers. On October 31, 2005, the Fund's duration was 4.22 years. This is close to the top of the range and nearly a half year longer than the Fund's duration when the 12-month reporting period began. As we had anticipated, rising mortgage rates slowed prepayments of the loans that collateralize the Fund's mortgage-backed securities, which caused the Fund's duration to lengthen during the reporting period. WHAT OTHER DECISIONS HAD A POSITIVE IMPACT ON THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? The Fund benefited from our efforts to take advantage of a flattening Treasury yield curve. We increased the Fund's long-term exposure by adding long-dated agency debentures that offered a yield advantage over Treasury bonds. The Fund's agency debentures also generated attractive excess returns when compared to Treasury securities with similar durations. We also managed the Fund's mortgage- related extension risk by overweighting mortgage-backed securities that are less sensitive to prepayments. Finally, the Fund's position in Treasury Inflation-Protected Securities outperformed similar-duration Treasurys when the price of crude oil spiked.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Government Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Class A shares, whose distribution commenced on January 3, 1995, are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Distribution of Class B shares and Class C shares commenced on May 1, 1986 and September 1, 1998, respectively. Class I shares are not subject to sales charge. Distribution of Class I shares commenced on January 2, 2004. Class A shares, Class B shares, Class C shares and Class I shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions. Each class of shares other than Class I shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution or service fee. The Fund's investment objective is to seek a high level of current income, consistent with safety of principal. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Debt securities are valued at prices supplied by a pricing agent or brokers selected by the Fund's Manager, whose prices reflect broker/dealer supplied valuations and electronic data processing techniques, if such prices are deemed by the Fund's Manager to be representative of market values, at the regular close of business of the New York Stock Exchange. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) MORTGAGE DOLLAR ROLLS. The Fund enters into mortgage dollar roll ("MDR") transactions in which it sells mortgage-backed securities ("MBS") from its portfolio to a counterparty from whom it simultaneously agrees to buy a similar security on a delayed delivery basis. The MDR transactions of the Fund are classified as purchase and sale transactions. The securities sold in connection with the MDRs are removed from the portfolio and a realized gain or loss is recognized. The securities the Fund has agreed to acquire are included at market value in the portfolio of investments and liabilities for such purchase commitments are included as payables for investments purchased. During the roll period, a Fund forgoes principal and interest on the securities. A Fund is compensated by the difference between the current sales price and the forward price for the future purpose as well as by the earnings on the cash proceeds of the initial sale. MDRs may be renewed without physical delivery of the securities subject to the contract. The Fund maintains a segregated account with its custodian containing securities from its portfolio having a value not less than the repurchase price, including accrued interest. MDR transactions involve certain risks, including the risk that the MBS returned to the Fund at the end of the roll, while substantially similar, could be inferior to what was initially sold to the counterparty. (C) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 7.) 18 MainStay Government Fund (D) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends monthly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between distributions in excess of net investment income, net realized loss and additional paid-in capital arising from permanent differences; net assets at October 31, 2005 are not affected. <Table> <Caption> UNDISTRIBUTED ACCUMULATED NET REALIZED NET INVESTMENT INCOME LOSS ON INVESTMENTS $545,696 $ (545,696) ---------------------------------------------------- </Table> The reclassification for the Fund is primarily due to paydowns. (F) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method and includes gains and losses from repayments of principal on mortgage-backed securities. Interest income is accrued as earned. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Income from payment-in-kind securities is recorded daily based on the effective interest method of accrual. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (G) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (H) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (I) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. www.MAINSTAYfunds.com 19 NOTES TO FINANCIAL STATEMENTS (CONTINUED) The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.60% on assets up to $1 billion and 0.55% on assets in excess of $1 billion. In addition, effective August 1, 2004, NYLIM voluntarily agreed to waive its management fee by 0.10% on assets up to $1 billion and 0.45% on assets in excess of $1 billion. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.05% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $302,892 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM had agreed to voluntarily reimburse the expenses of the Fund so that the total operating expenses would not exceed on an annualized basis 1.05% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $2,375,635, and waived its fee and/or reimbursed expenses in the amount of $1,157,488. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee of 0.30% of the Fund's average daily net assets on assets up to $1 billion and 0.275% on assets in excess of $1 billion. To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, other than Class I shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $23,490 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $6,500, $215,418 and $1,780, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $1,520,220. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective 20 MainStay Government Fund Funds. Thus the Fund only pays a portion of the fees identified above. F) CAPITAL. At October 31, 2005, New York Life and its affiliates held shares of Class I with a net asset value of $1,009. This represents 6.2% of the Class I shares net assets and less than one-tenth of one percent of the Fund's total net assets at October 31, 2005. (G) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $10,303 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $66,261 for the year ended October 31, 2005. NOTE 4--CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, State Street Bank and Trust Company acted as custodian for the Fund. NOTE 5--FEDERAL INCOME TAX: As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> ACCUMULATED UNDISTRIBUTED NET ACCUMULATED OTHER TOTAL INVESTMENT CAPITAL TEMPORARY UNREALIZED ACCUMULATED INCOME LOSSES DIFFERENCES APPRECIATION LOSS $112,342..... $(39,793,212) $(125,344) $(3,647,830) $(43,454,044) ----------------------------------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to premium amortization adjustments. At October 31, 2005, for federal income tax purposes, capital loss carryforwards of $39,793,212 were available as shown in the table below, to the extent provided by the regulations to offset future realized gains of the Fund through the years indicated. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to shareholders. <Table> <Caption> CAPITAL LOSS AMOUNTS AVAILABLE THROUGH (000'S) 2007 $29,405 2008 6,930 2012 3,458 ------------------------------------------- $39,793 ------------------------------------------- </Table> The Fund utilized $2,551,413 of capital loss carryforwards during the year ended October 31, 2005.

NOTE 10--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay Government Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. 22 MainStay Government Fund REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Government Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Government Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 www.MAINSTAYfunds.com 23 TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's underperformance when compared over several time periods with funds concluded by Trustees to be peers of the Fund, and the means outlined by the Manager and the Subadvisor to the Board designed to address the Fund's comparative performance. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distribut- www.MAINSTAYfunds.com 27 ing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. 28 MainStay Government Fund IMPORTANT TAX INFORMATION (UNAUDITED) For State individual income tax purposes, the Fund hereby designates 27.75% of the ordinary income dividends paid during its fiscal year ended October 31, 2005 as attributable to interest income from Direct Obligations of the United States.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ Christopher O. Blunt Christopher O.

This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six-months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED ON HYPOTHETICAL BEGINNING ON ACTUAL EXPENSES 5% RETURN EXPENSES ACCOUNT RETURNS AND PAID AND ACTUAL PAID VALUE EXPENSES) DURING EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,042.60 $5.25 $1,019.90 $5.19 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,037.95 $9.09 $1,016.15 $8.99 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,037.95 $9.09 $1,016.15 $8.99 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,041.75 $4.17 $1,020.95 $4.13 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Morgan and J. Matthew Philo of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 80% of its assets in high-yield corporate debt securities, including all types of high-yield domestic and foreign corporate debt securities that are rated below investment grade by Moody's or S&P or, if unrated, that we consider to be of comparable quality. In implementing this strategy, we seek to identify investment opportunities based primarily on the financial condition and competitiveness of individual companies. The Fund's principal investments include domestic corporate debt securities, Yankee or dollar-denominated debt securities, zero coupon bonds, U.S. government securities, convertible corporate bonds, and loan participation interests. The Fund may invest up to 20% of its assets in equity securities and may invest up to 20% of its net assets in securities rated lower than B by Moody's and S&P.(1) WHAT WERE SOME OF THE TRENDS THAT DROVE THE HIGH-YIELD MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? Despite periods of volatility, the high-yield market generated positive results during the reporting period. The most significant factor facing the market was the tight yield spread(2) between high-yield bonds and U.S. Treasury bonds. This may perhaps account for the flow of funds away from high-yield mutual funds during the reporting period. High-yield default rates have remained at historical lows. For the first 10 months of 2005, the high-yield new-issue market slowed from its record pace in 2004. We believe that the overall quality of new issues has declined. WHAT EFFECT DID THESE MARKET TRENDS HAVE ON THE FUND? Traditionally, high-yield bond spreads reflect the amount of additional yield investors receive for assuming additional risk. In response to the low yield-spread environment, we broadly diversified the Fund and reduced or eliminated positions that carried higher risk. Slower new issuance and lower- quality offerings limited a key source of new investments for the Fund. In the wake of strong high-yield performance in 2003 and 2004, the secondary market also provided fewer buying opportunities that we considered attractive. As a result, cash levels in the Fund rose during the reporting period. Higher-than-normal tenders from bond issuers have also added to the Fund's cash level. (A tender is a payment for bonds called prior to maturity.) HOW DID YOU POSITION THE FUND FROM AN INDUSTRY PERSPECTIVE? We are bottom-up investors, so the Fund's exposure to various sectors and industries is primarily the result of individual security selection. During the 12 months ended October 31, 2005, we reduced the Fund's exposure to bonds in the utilities, cable, and broadcasting industries.(3) Over the same period, we increased the Fund's absolute weightings in automotive, information technology, diversified media, retail, and real estate development bonds. At the end of the reporting period, the Fund's largest overweighted positions relative to the Credit Suisse First Boston(TM) High Yield Index(4) were in the information technology, financial, real estate development, High-yield debt securities ("junk bonds") are generally considered speculative because they present a greater risk of loss than higher- quality debt securities and may be subject to greater price volatility. Foreign securities may be subject to greater risks than U.S. investments, including currency fluctuations, less-liquid trading markets, greater price volatility, political and economic instability, less publicly available information, and changes in tax or currency laws or monetary policy. These risks are likely to be greater in emerging markets than in developed markets. The Fund may experience a portfolio turnover rate of over 100% and may generate short-term capital gains, which are taxable. Funds that invest in bonds are subject to interest-rate risk and can lose principal value when interest rates rise. 1. Bonds rated B by Moody's Investors Service are deemed by Moody's to generally lack characteristics of the desirable investment. According to Moody's, assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small. Debt rated B by Standard & Poor's is deemed by Standard & Poor's to be more vulnerable to nonpayment than obligations rated BB, but it is the opinion of Standard & Poor's that the obligor currently has the capacity to meet its financial commitment on the obligation. Standard & Poor's believes that adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation. When applied to Fund holdings, ratings are based solely on the creditworthiness of the bonds in the portfolio and are not meant to represent the security or safety of the Fund. 2. The terms "spread" and "yield spread" may refer to the difference in yield between a specific security or type of security and comparable U.S. Treasury issues. The terms may also refer to the difference in yield between two specific securities or types of securities at a given time. 3. Industries mentioned in the Portfolio Management Discussion and Analysis are those included in the Credit Suisse First Boston(TM) High Yield Index. Industries in the Portfolio of Investments reflect the Global Industry Classification Standard (GICS) developed by Standard & Poor's and MSCI. 4. See footnote on page 4 for more information on the Credit Suisse First Boston(TM) High Yield Index. www.MAINSTAYfunds.com 7 packaging, and medical products industries. At the same time, the Fund held underweighted positions relative to the Index in gaming, utility, manufacturing, consumer non-durables, and food and drug bonds. DID YOU ADJUST THE FUND'S DURATION POSITIONING DURING THE REPORTING PERIOD? As bottom-up investors, duration is primarily a residual of our investment process. We believe that high-yield bonds have risk and reward characteristics similar to those of equities. As a result, traditional fixed-income strategies, such as yield-curve positioning, maturity structure, and duration management are not the focal point of our investment process. That said, we believe that our general duration parameters of plus or minus 10% relative to the benchmark index may serve to reduce the duration risk of the Fund. The duration of the high-yield market has historically fluctuated around four years. This is true for several reasons. Coupons are generally higher than those of investment-grade fixed-income securities, few high-yield bonds are issued with maturities of 15 or more years, and call provisions often allow for refinancing. Given the low-spread and rising-rate environment during the reporting period, the Fund has had a shorter duration than its benchmark index. WHICH SECURITIES WERE STRONG AND WEAK PERFORMERS DURING THE REPORTING PERIOD? The Fund's top performers included At Home, UnitedGlobalCom, ICO Global Communications Holdings, President Casinos, and General Motors Acceptance Corp. The Fund's weak performers included Collins & Aikman Products, Northwest Airlines, Delta Air Lines, Globix Corp., and Abitibi-Consolidated. At Home, an Internet service provider that filed for bankruptcy protection in 2001, had partnered with several prominent cable partners, the largest of which was AT&T. The company reached a substantial settlement with AT&T weeks before a major lawsuit was to go to trial. This resulted in a significant award that helped the Fund's performance. While the market had priced in the possibility of defaults before Delta Air Lines and Northwest Airlines filed for bankruptcy in September 2005, the airline industry as a whole showed poor performance during the reporting period. Rising oil prices and their impact on the cost of jet fuel drove the Fund's investments in Delta Air Lines and Northwest Airlines downward. The Fund continues to hold Delta and Northwest because we see attractive value in these companies relative to their current trading levels. Bonds of automakers General Motors and Ford Motor traded at yields comparable to high-yield issuers for several months before both companies faced credit downgrades by Moody's and S&P in early May 2005. We initiated a large position in General Motors Acceptance Corp. (GMAC) earlier in 2005, before the debt was downgraded. GMAC now constitutes a large part of the high-yield market. We view GMAC as a separate issuer from General Motors because the companies have distinctly separate assets covering their bonds, separate financial statements, and separate boards. News reports that General Motors has considered selling or spinning off GMAC have strengthened the performance of GMAC bonds. WERE THERE ANY OTHER AREAS THAT DIDN'T MEET YOUR EXPECTATIONS? The Fund's position in automotive interior components and systems manufacturer Collins & Aikman Products had a significant negative impact on performance. When the auto industry suffered in the first quarter of 2005, we met with Collins & Aikman's management team. A few weeks after our meeting, the CEO was forced out by the company's board and accounting irregularities were disclosed. The bonds traded down sharply, and the company filed for bankruptcy protection. WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? During the 12 months ended October 31, 2005, we established positions in General Motors Acceptance Corp. and added to CanWest Media, Qwest Services, El Paso/Cedar Brakes, and Qwest Communications International. Significant sales during the reporting period included UnitedGlobalCom, El Paso/Cedar Brakes, Hollinger Participation Trust, TSI Telecommunications, and FrontierVision Capital Corp.

These financial statements and notes relate only to MainStay High Yield Corporate Bond Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Class A shares, whose distribution commenced on January 3, 1995, are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Distribution of Class B shares and Class C shares commenced on May 1, 1986 and September 1, 1998, respectively. Class I shares are not subject to a sales charge. Distribution of Class I shares commenced on January 2, 2004. Class A shares, Class B shares, Class C shares and Class I shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation, and other rights and conditions except that Class B shares and Class C shares are subject to higher distribution fee rates than Class A shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution or service fee. The Fund's investment objective is to seek maximum income through investment in a diversified portfolio of high yield debt securities. Capital appreciation is a secondary objective. The Fund invests in high yield securities (sometimes called "junk bonds"), which are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. These securities pay a premium--a high interest rate or yield--because of the increased risk of loss. These securities can also be subject to greater price volatility. The Fund also invests in foreign securities which carry certain risks that are in addition to the usual risks inherent in domestic instruments. These risks include those resulting from currency fluctuations, future adverse political and economic developments and possible imposition of currency exchange blockages or other foreign governmental laws or restrictions. These risks are likely to be greater in emerging markets than in developed markets. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country, industry or region. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Debt securities are valued at prices supplied by a pricing agent or brokers selected by the Fund's Manager, whose prices reflect broker/dealer supplied valuations and electronic data processing techniques, if such prices are deemed by the Fund's Manager to be representative of market values, at the regular close of business of the New York Stock Exchange. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices are normally taken from the principal market in which each security trades. Foreign currency forward contracts are valued at their fair market values determined on the basis of the mean between the last current bid and asked prices based on dealer or exchange quotations. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. At October 31, 2005, the Fund held securities with a value of $27,186,592 that were valued in such manner. Certain events may occur between the time that foreign markets close, on which securities held by the Fund principally trade, and the time at which the Fund's NAV is calculated. These events may include, but are not limited to, situations relating to a single issue in a market sector, significant fluctuations in U.S. or foreign markets, natural disasters, armed conflicts, governmental actions or other developments not tied directly to the securities markets. Should the Manager or Subadvisor conclude that such events may have effected the accuracy of the last price reported on the local foreign market, the Manager or Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of the local price to reflect the 26 MainStay High Yield Corporate Bond Fund impact on the price of such securities as a result of such events. (B) FOREIGN CURRENCY FORWARD CONTRACTS. A foreign currency forward contract is an agreement to buy or sell currencies of different countries on a specified future date at a specified rate. During the period the forward contract is open, changes in the value of the contract are recognized as unrealized gains or losses by "marking to market" such contract on a daily basis to reflect the market value of the contract at the end of each day's trading. When the forward contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. The Fund enters into foreign currency forward contracts primarily to hedge its foreign currency denominated investments and receivables and payables against adverse movements in future foreign exchange rates or to try to enhance the Fund's returns. The use of foreign currency forward contracts involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statement of Assets and Liabilities. The contract amount reflects the extent of the Fund's involvement in these financial instruments. Risks arise from the possible movements in the foreign exchange rates underlying these instruments. The unrealized appreciation on forward contracts reflects the Fund's exposure at period end to credit loss in the event of a counterparty's failure to perform its obligations. (See Note 7). (C) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 7). (D) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS. The Fund invests in loan assignments and loan participations. Loan assignments and participations are agreements to make money available (a "commitment") to a borrower in a specified amount, at a specified rate and within a specified time. Such loan assignments and participations are typically senior, secured and collateralized in nature. The Fund records an investment when the borrower withdraws money and records interest as earned. These loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or London InterBank Offered Rate (LIBOR). The loans in which the Fund invests are generally readily marketable, but may be subject to some restrictions on resale. The Fund may be contractually obligated to receive approval from the agent bank and/or borrower prior to the sale of these investments. The Fund assumes the credit risk of the Borrower, the Selling Participant and any other persons interpositioned between the Fund and the Borrower ("Intermediate Participants"). In the event that the Borrower, Selling Participant or Intermediate Participants becomes insolvent or enters into bankruptcy, the Fund may incur certain costs and delays in realizing payment, or may suffer a loss of principal and/or interest. Unfunded commitments represent the remaining obligation of the Fund to the Borrower. At any point in time, up to the maturity date of the issue, the Borrower may demand the unfunded portion. These unfunded amounts are recorded in memorandum accounts. (E) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (F) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends monthly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between accumulated distributions in excess of net investment income and accumulated net realized loss on investments arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> ACCUMULATED DISTRIBUTIONS IN ACCUMULATED NET EXCESS OF NET REALIZED LOSS ON INVESTMENT INCOME INVESTMENTS $11,301,385 $ (11,301,385) - -------------------------------------------------- </Table> www.MAINSTAYfunds.com 27 NOTES TO FINANCIAL STATEMENTS (CONTINUED) The reclassifications for the Fund are primarily due to premium amortization adjustments and foreign currency gain (loss). (G) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Income from payment-in-kind securities is recorded daily based on the effective interest method of accrual. The investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. The Fund may place a debt obligation on non-accrual status and reduce related interest income by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured. (H) FOREIGN CURRENCY TRANSACTIONS. The books and records of the Fund are kept in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean between the buying and selling rates last quoted by any major U.S. bank at the following dates: (i) market value of investment securities, other assets and liabilities--at the valuation date, (ii) purchases and sales of investment securities, income and expenses--at the date of such transactions. The assets and liabilities are presented at the exchange rates and market values at the close of the period. The realized and unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. Net realized gain (loss) on foreign currency transactions represents net gains and losses on foreign currency forward contracts, net currency gains or losses realized as a result of differences between the amounts of securities sale proceeds or purchase cost, dividends, interest and withholding taxes as recorded on the Fund's books, and the U.S. dollar equivalent amount actually received or paid. Net currency gains or losses from valuing such foreign currency denominated assets and liabilities, other than investments, are reflected in unrealized foreign exchange gains or losses at period end exchange rates. (I) RESTRICTED SECURITIES. A restricted security is a security which has been purchased through a private offering and cannot be resold to the general public without prior registration under the Securities Act of 1933 (the "1933 Act"). The Fund does not have the right to demand that such securities be registered. Disposal of these securities may involve time-consuming negotiations and expense and prompt sale at an acceptable price may be difficult. (See Note 7). (J) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (K) REDEMPTION FEE. The Fund imposes a 2.00% redemption fee on redemptions (including exchanges) of Fund shares made within 60 days of their date of purchase for each class of shares. The redemption fee is designed to offset brokerage commissions and other costs associated with short-term trading and is not assessed on the shares acquired through the reinvestment of dividends or distributions paid by the Fund. The redemption fees are included in the Statement of Changes in Net Assets' shares redeemed amount and retained by the Fund. (L) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (M) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. 28 MainStay High Yield Corporate Bond Fund NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR.

NOTE 10--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the Funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay High Yield Corporate Bond Funds was $814,000. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that Fund as well as the related guarantee disclosure to Fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. 32 MainStay High Yield Corporate Bond Fund REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay High Yield Corporate Bond Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year period then ended. These financial statements and financial highlights are the responsibility of this 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay High Yield Corporate Bond Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 www.MAINSTAYfunds.com 33 TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's performance (top decile) when compared over several time periods with funds concluded by Trustees to be peers of the Fund. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees, in considering economies of scale, noted the Fund was the largest series of The MainStay Funds. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted that a contractual breakpoint was in place for the management fee and was intended to provide that the Fund's shareholders would share in benefits from economies of scale as the Fund grows. The Trustees noted that the Fund's contractual management fee had been reduced in accordance with the www.MAINSTAYfunds.com 37 terms of the breakpoint schedule applicable to the Fund, and reviewed information provided by the Manager intended to show that the profitability of the Fund to the Manager and the Subadviser was not excessive. In discussing the large size of the Fund relative to the low asset level at which the breakpoint became applicable, the Manager emphasized the increase of the Manager's and Subadvisor's costs applicable to the Fund as its assets have increased, the lack of a significant increase of the Manager's and Subadvisor's profitability level relating to the Fund, the Fund's competitive fee level, and the Manager's willingness to keep the Fund open to new investors. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated expense ratio, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. 38 MainStay High Yield Corporate Bond Fund FEDERAL INCOME TAX INFORMATION (UNAUDITED) The dividends paid by the Fund during the fiscal year ended October 31, 2005, should be multiplied by 0.2% to arrive at the amount eligible for qualified dividend income and 0.1% for the corporate dividends received deduction.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /S/ CHRISTOPHER O. BLUNT Christopher O.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,032.40 $ 8,91 $1,016.30 $ 8.84 - ------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,028.45 $12.73 $1,012.55 $12.63 - ------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,028.45 $12.73 $1,012.55 $12.63 - ------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,034.25 $ 6.00 $1,019.15 $ 5.95 - ------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,031.25 $ 6.50 $1,018.65 $ 6.46 - ------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,032.10 $ 7.79 $1,017.40 $ 7.73 - ------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Bhansali of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund seeks to generate superior risk-adjusted returns by investing in quality companies that we believe are currently undervalued. The Fund normally invests at least 80% of its assets in equity securities of issuers, wherever organized, who do business mainly outside the United States. Investments will be made in a variety of countries with established economies, as well as emerging-market countries that we believe present favorable opportunities. In implementing this strategy, we utilize a bottom-up stock-picking investment discipline. Proprietary quantitative and qualitative tools are used to identify attractive companies. In-depth, original fundamental research is performed on identified companies to assess their business and investment prospects. Particular attention is paid to cash flow, return on invested capital, and management's demonstrated ability to create shareholder value. Portfolios are constructed by combining securities with low correlation. Quantitative tools are used for risk control at the portfolio level. Country allocations in the portfolio are a result of the bottom-up stock-selection process. To reduce risk, an attempt is made at the portfolio level to stay within a reasonable range of the key constituents of the MSCI EAFE(R) Index,(1) unless the stock-selection process strongly argues against it. WHAT MAJOR FACTORS INFLUENCED INTERNATIONAL EQUITIES DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? International equity markets advanced significantly during the 12-month reporting period. The global focus on high energy prices sparked renewed concerns about higher inflation. In Japan, good corporate sector performance has begun to spill into the household sector, creating a recovery path that will likely be led by private demand. From a price per-spective, the Japanese economy was still in a mild deflationary period. Still, the possible economic ramifications of oil price fluctuations on Japan's domestic and overseas businesses could not be ignored. In Europe, economic news was mixed. The euro hit a record high versus the U.S. dollar in November 2004 and has since declined in value. The European Central Bank has expressed concern about the weakness but has not yet been moved to raise interest rates. In the United States, corporate profit growth and higher commodity prices once again ignited inflation fears, but the Federal Open Market Committee continued to raise the targeted federal funds rate at a measured pace, with eight 25-basis-point increases during the reporting period. (A basis point is one-hundredth of a percentage point.) At the end of October 2005, the federal funds target rate stood at 3.75%, and the market anticipated additional tightening moves. The key factor driving international markets, however, was not interest rates but an appetite for risk. The more-volatile parts of the global economy continued to outperform during the reporting period. With gross domestic product showing strength worldwide, emerging markets, commodity-related stocks, and high-fixed-cost companies continued to enjoy market favor. WHAT WERE THE STRONGEST AND WEAKEST AREAS OF THE MARKET DURING THE REPORTING PERIOD? The international equity market saw broad-based advances during the 12-month period ended October 31, 2005, with every sector recording gains. Within the MSCI EAFE(R) Index, the materials and energy sectors were the best performers in U.S. dollar terms. Telecommunications services and information technology were the worst-performing sectors, although they still generated positive returns in U.S. dollars during the reporting period. WHICH FUND HOLDINGS DID PARTICULARLY WELL DURING THE REPORTING PERIOD? Deutsche Boerse, a German-based provider of various stock-exchange services, was one of the strongest positive contributors to the Fund's performance during the reporting period. The company approved a significant share-buyback program during the reporting period and did not rule out a dividend payout ratio increase. Ryanair Holdings, an Ireland-based low-cost airline that operates through Europe, was another strong performer. The company continued to increase business and profits while other airlines were struggling with the high cost of fuel. At a time when high fuel prices were forcing many competitors out of business, Ryanair actually flew more passengers than British Airways. Another positive contributor was Nestle, the Switzerland-based Foreign securities may be subject to greater risks than U.S. investments, including currency fluctuations, less-liquid trading markets, greater price volatility, political and economic instability, less publicly available information, and changes in tax or currency laws or monetary policy. These risks are likely to be greater in emerging markets than in developed markets. The Fund may invest in derivatives, which may increase the volatility of the Fund's net asset value and may result in a loss to the Fund. The Fund may experience a portfolio turnover rate of over 100% and may generate short-term capital gains which are taxable. 1. See footnote on page 5 for more information on the MSCI EAFE(R) Index. 8 MainStay International Equity Fund food manufacturer, whose businesses include coffee, infant formula, bottled water, and pet food. Of particular note was Nestle's lucrative bottled-water business, because bottled water has become a powerhouse in the global beverage market. WHAT STOCKS DETRACTED FROM RESULTS? Enel, the largest Italian electric utility, detracted from the Fund's performance during the reporting period. The company's cash position was affected by a change in the Italian government's rules on amortization of property, plant, and equipment. Another stock that hurt performance was Kingfisher, a do-it-yourself retailer that faced profit problems in a deteriorating U.K. retail environment. Tesco, a U.K. retailing giant, declined when the market responded negatively to the actions of Asda, a competitor owned by Wal-Mart Stores. WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? We added Roche Holdings, a Switzerland-based pharmaceutical company, to the Fund's portfolio during the reporting period because of the company's strong growth prospects, which were strengthened by increased penetration in the oncology field. Roche also has a solid pipeline of products that many analysts appear to have ignored in their forecasts. We also initiated a Fund position in Denso, an auto parts manufacturer based in Japan. Although we have concerns about projected auto sales, we feel that as the main supplier to Toyota, Denso may benefit. Toyota is one of the few automakers that has gained market share globally. We also added to several of the Fund's energy positions, including BP and Total, because earnings expectations have not kept up with the rising price of oil. We eliminated the Fund's position in Euronext, a pan-European stock exchange that resulted from the merger of exchanges in Paris, Brussels, Amsterdam, and Lisbon. The decision to sell Euronext was driven by concerns that the winds of consolidation would lead the company to overpay for the acquisition of the London Stock Exchange. For this reason, we felt it prudent to liquidate the Fund's position. The Fund took profits in Porsche, an automaker known for its premium sports cars and new Cayenne SUV. We decided to sell the stock after we learned that the company's management had decided to acquire a 20% stake in Volkswagen. We believed that Volkswagen's business model was not up to par and that shareholders would have been better served if the money had been returned to them or invested in Porsche's own high-return business. HOW WAS THE FUND POSITIONED RELATIVE TO THE MSCI EAFE(R) INDEX AS OF OCTOBER 31, 2005? The Fund and its benchmark were invested primarily in stocks of developed markets. The Fund tends to have limited exposure to emerging markets. As always, we remained focused on the fundamental analysis of individual businesses rather than on the market's perception. At the end of October 2005, the Fund was overweighted in diversified financials and higher-dividend-yielding sectors, such as consumer staples and utilities. The Fund was also slightly overweighted in health care. At the same time, the Fund was underweighted in telecommunications services, industrials, and materials. The Fund held a market-weighted position in information technology. During the reporting period, the Fund's holdings in diversified financials and health care provided the biggest contribution to absolute performance. The Fund's utility holdings detracted from absolute performance. WHERE HAVE YOU RECENTLY FOUND THE MOST COMPELLING OPPORTUNITIES? We have found promising opportunities in Europe and Asian nations outside Japan. Since we find Japanese companies less compelling, the Fund has been underweighted relative to the Index in Japan.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to Mainstay International Equity Fund (the "Fund"), a diversified fund. The Fund currently offers six classes of shares, Class A shares, Class B shares, Class C shares, Class I shares, Class R1 shares and Class R2 shares. Class A shares, whose distribution commenced on January 3, 1995, are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class I, Class R1 and Class R2 shares are not subject to a sales charge. Distribution of Class B shares and Class C shares commenced on September 13, 1994 and September 1, 1998, respectively. Distribution of Class I shares, Class R1 shares and Class R2 shares commenced on January 2, 2004. The six classes of shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions except that Class B shares and Class C shares are subject to higher distribution fee rates than Class A shares and Class R2 shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares and Class R1 shares are not subject to a distribution or service fee. Class R1 and Class R2 shares are authorized to pay to New York Life Investment Management LLC, its affiliates, or independent third-party service providers, as compensation for services rendered to shareholders of Class R1 or Class R2 shares, a shareholder service fee. The Fund's investment objective is to provide long-term growth of capital commensurate with an acceptable level of risk by investing in a portfolio consisting primarily of non-U.S. equity securities. Current income is a secondary objective. The Fund invests in foreign securities which carry certain risks that are in addition to the usual risks inherent in domestic instruments. These risks include those resulting from currency fluctuations, future adverse political and economic developments and possible imposition of currency exchange blockages or other foreign governmental laws or restrictions. These risks are likely to be greater in emerging markets than in developed markets. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country, industry or region. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such a manner. Foreign currency forward contracts are valued at their fair market values determined on the basis of the mean between the last current bid and asked prices based on dealer or exchange quotations. Certain events may occur between the time that foreign markets close, on which securities held by the Fund principally trade, and the time at which the Fund's NAV is calculated. These events may include, but are not limited to, situations relating to a single issue in a market sector, significant fluctuations in U.S. or foreign markets, natural disasters, armed conflicts, governmental actions or other developments not tied directly to the securities markets. Should the Manager or Subadvisor conclude that such events may have effected the accuracy of the last price reported on the local foreign market, the Manager or Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of the local price to reflect the impact on the price of such securities as a result of such events. (B) FOREIGN CURRENCY FORWARD CONTRACTS. A foreign currency forward contract is an agreement to buy or 20 MainStay International Equity Fund sell currencies of different countries on a specified future date at a specified rate. During the period the forward contract is open, changes in the value of the contract are recognized as unrealized gains or losses by "marking to market" such contract on a daily basis to reflect the market value of the contract at the end of each day's trading. When the forward contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. The Fund enters into foreign currency forward contracts primarily to hedge its foreign currency denominated investments and receivables and payables against adverse movements in future foreign exchange rates or to try to enhance the Fund's returns. The use of foreign currency forward contracts involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statement of Assets and Liabilities. The contract amount reflects the extent of the Fund's involvement in these financial instruments. Risks arise from the possible movements in the foreign exchange rates underlying these instruments. The unrealized appreciation on forward contracts reflects the Fund's exposure at period end to credit loss in the event of a counterparty's failure to perform its obligations. (see Note 7). (C) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (see Note 7). (D) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between undistributed net investment income, accumulated net realized gain on investments, and paid-in capital. <Table> <Caption> ACCUMULATED NET UNDISTRIBUTED REALIZED GAIN ON PAID-IN- NET INVESTMENT INCOME INVESTMENTS CAPITAL $(932,655) $931,504 $1,151 ---------------------------------------------------- </Table> The reclassification for the Fund is primarily due to foreign currency gain (loss). (F) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (G) FOREIGN CURRENCY TRANSACTIONS. The books and records of the Fund are kept in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean between the buying and selling rates last quoted by any major U.S. bank at the following dates: (i) market value of investment securities, other assets and liabilities--at the valuation date, (ii) purchases and sales of investment securities, income and expenses--at the date of such transactions. The assets and liabilities are presented at the exchange rates and market values at the close of the period. The realized and unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. Net realized gain (loss) on foreign currency transactions represents net gains and losses on foreign currency forward contracts, net currency gains or losses realized as a result of differences between the amounts of securities sale proceeds or purchase cost, dividends, interest and www.MAINSTAYfunds.com 21 NOTES TO FINANCIAL STATEMENTS (CONTINUED) withholding taxes as recorded on the Fund's books, and the U.S. dollar equivalent amount actually received or paid. Net currency gains or losses from valuing such foreign currency denominated assets and liabilities, other than investments, are reflected in unrealized foreign exchange gains or losses at period end exchange rates. (H) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (I) REDEMPTION FEE. The Fund imposes a 2.00% redemption fee on redemptions (including exchanges) of Fund shares made within 60 days of their date of purchase for Class A, Class B, Class C and Class I shares. The redemption fee is designed to offset brokerage commissions and other costs associated with short-term trading and is not assessed on the shares acquired through the reinvestment of dividends or distributions paid by the Fund. The redemption fees are included in the Statement of Changes in Net Assets' shares redeemed amount and retained by the Fund. (J) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (K) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.90% on assets up to $500 million and 0.85% on assets in excess of $500 million. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.75% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $33,294 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM agreed to voluntarily reimburse the expenses of the Fund so that the total operating expenses would not exceed on an annualized basis 1.95% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $2,301,353 and waived its fee and/or reimbursed expenses in the amount of $39,296. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee of 0.60% of the Fund's average daily net assets of the Fund. To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to Class A, Class B, Class C, and Class R2 22 MainStay International Equity Fund shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A and Class R2 Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A and Class R2 shares, which is an expense of the Class A and Class R2 shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. The Fund has adopted a shareholder services plan with respect to Class R1 and Class R2 shares. Under the terms of this plan, Class R1 and Class R2 shares are authorized to pay to NYLIM, its affiliates, or independent third-party providers, as compensation for services rendered, a shareholder services fee at the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2 shares. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $462,015 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $5,705, $63,443 and $1,830, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent.

NOTE 10--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay International Equity Fund was $772,000. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 25 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay International Equity Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay International Equity Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 26 MainStay International Equity Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's top quartile performance over longer time periods when compared with funds concluded by Trustees to be peers of the Fund and its shorter term mid-range performance compared with those funds. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the 30 MainStay International Equity Fund Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 31 FEDERAL INCOME TAX INFORMATION (UNAUDITED) In accordance with federal tax law, the Fund elects to provide each shareholder with their portion of the Fund's foreign taxes paid and the income sourced from foreign countries.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ Christopher O. Blunt Christopher O.

Total returns reflect change in share price, reinvestment of dividend and capital-gain distributions, and maximum applicable sales charges explained in this paragraph. The graphs assume an initial investment of $10,000 and reflect the deduction of all sales charges that would have applied for the period of investment. Class A shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1 fee of .25%. Class B shares are sold with no initial sales charge, are subject to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are subject to a CDSC of 1% if redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%. Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. The fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. Class I shares are sold with no initial sales charge or CDSC, have no annual 12b-1 fee, and are generally available to corporate and institutional investors with a minimum initial investment of $5 million. From inception through 3/28/05 performance of Class I shares (first offered 3/29/05) includes the historical performance of Class A shares adjusted to reflect the applicable sales charge (or CDSC) and fees and expenses for Class I shares.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED ON HYPOTHETICAL BEGINNING ON ACTUAL EXPENSES 5% RETURN EXPENSES ACCOUNT RETURNS AND PAID AND ACTUAL PAID VALUE EXPENSES) DURING EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD 10/31/05 PERIOD CLASS A SHARES(1) $1,000.00 $1,148.10 $ 8.12 $1,017.50 $ 7.63 - ------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES(1) $1,000.00 $1,143.15 $12.15 $1,013.75 $11.42 - ------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES(1) $1,000.00 $1,145.45 $12.17 $1,013.75 $11.42 - ------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES(1) $1,000.00 $1,149.60 $ 5.96 $1,019.50 $ 5.60 - ------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Spelman of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 80% of its assets in companies with market capitalizations that, at the time of investment, are similar to the market capitalizations of companies in the Russell Midcap(R) Growth Index(1) and invests primarily in U.S. common stocks and securities related to U.S. common stocks. The Fund seeks to participate primarily in the expanding markets of technology, health care, communications, and other dynamic high-growth industries. We also seek stocks with above-average growth in earnings. We select investments according to the economic environment and the attractiveness of particular markets, as well as the financial condition and competitiveness of individual companies. In implementing this strategy, we use a flexible approach and may invest in various types of companies and securities. We look for securities that we believe may be poised for a rise in price or an acceleration in earnings growth--possibly because of special factors, such as changes in management, products, consumer demand, or the economy. We may sell a stock if its earnings growth rate decelerates, if it appears overvalued in relation to its growth rate or its peer group, or if the stock no longer appears likely to help the Fund meet its investment objective. WHAT MAJOR FACTORS AND RISKS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? Some of the most significant factors included Federal Reserve interest-rate hikes, high energy prices, rising inflation, and an apparent slowdown in the rate of corporate-earnings growth and economic advancement. The potential impact of hurricanes Katrina and Rita on the overall economy also weighed heavily on investor sentiment. WHAT FACTORS HAD THE GREATEST IMPACT ON THE FUND'S RELATIVE PERFORMANCE? During the reporting period, the Fund's strong performance relative to its peers and the Russell Midcap(R) Growth Index resulted primarily from effective individual security selection in the consumer discretionary, energy, health care, and materials sectors. The Fund's overweighted position in the energy sector also contributed positively to the Fund's relative results. On the other hand, adverse stock selection in the financials sector detracted from the Fund's performance. WHAT DECISIONS GUIDED THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? The most significant positive decision we made during the reporting period was to overweight the Fund's exposure to the consumer discretionary and energy sectors. Our decision to maintain the Fund's underweighted position in the information technology sector during the reporting period also proved beneficial. WHICH STOCKS WERE STRONG POSITIVE CONTRIBUTORS TO THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? Peabody Energy and Arch Coal are leading coal producers. Both companies benefited from robust earnings growth, healthy worldwide demand for coal, and sharply higher coal prices. PacifiCare Health Systems and Coventry Health Care are managed-care companies that benefited from solid enrollment trends, premium increases, and stringent containment of medical costs. Shares of PacifiCare Health Systems also benefited from a takeover offer at a substantial premium by UnitedHealth Group. Chico's FAS is a specialty retailer of exclusively designed, private-label casual and formal women's apparel. The company's sales and earnings performance was driven by strong merchandising and marketing strategies and by management's solid execution of the company's business plan. KB HOME is one of the nation's leading homebuilders. During the reporting period, the company's positive financial results were driven by market share gains, low interest rates, and a residential housing market that remained relatively healthy. Mid-capitalization companies are generally less established and their stocks may be more volatile and less liquid than the securities of larger companies. The Fund may experience a portfolio turnover rate of over 100% and may generate short-term capital gains, which are taxable. 1. See footnote on page 5 for information on the Russell Midcap(R) Growth Index. 8 MainStay Mid Cap Growth Fund WHICH STOCKS TOOK THE GREATEST TOLL ON THE FUND'S PERFORMANCE? First Marblehead is a Boston-based provider of student-loan services. The company saw its stock price decline sharply after Bank of America, a key client, rejected the automatic renewal of its contract with First Marblehead for direct-to-consumer private student loans. Claire's Stores is a leading international costume-jewelry retailer that suffered when the company strayed from its core women's accessory business into catalog sales. Overall corporate results were also hurt by the company's purchase of the Mr. Rags chain, which caters primarily to teenage boys. MannKind is a biopharmaceutical company focused on the development and commercialization of therapeutic products for diabetes, cancer, and inflammatory and autoimmune diseases. The company's stock price declined on concerns about additional spending requirements for the development of the company's inhalable insulin product for diabetics. Acxiom is a global information-management solutions company that suffered when revenue growth came under pressure on several fronts. The company saw declining volume in Europe, customer consolidations, ongoing competition from IBM, and increasing integration of enterprise software. Pacific Sunwear of California is a specialty retailer of private-label casual apparel for young men and women. The company's stock declined following reports of weaker-than-expected comparable-store sales growth. Maverick Tube, which manufactures and markets steel tubular products for the oil services industry, saw its share price decline on competitive concerns. Specifically, investors worried that pricing pressure from an increase in carbon grade tubular imports might make it difficult for Maverick Tube to meet its revenue and earnings goals. WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD? Yes. In the health care sector, we added Omnicare, Health Net, Health Management Associates, Invitrogen, and WellChoice to the Fund. Omnicare provides professional pharmacy and data management services to skilled nursing, assisted living, and other institutional health care providers. The company's results are being bolstered by timely acquisitions. Health Net and WellChoice are managed-care companies that have benefited from strong enrollment and industry pricing trends. Health Management Associates is a Naples-based hospital- management company, which stands to benefit from favorable demographic trends in Florida. Invitrogen is a leading provider of research products and services to academic, government, biotechnology, and biopharmaceutical clients. The company is enjoying double-digit bottom-line growth because of robust demand for its products and services. In the energy sector, we added Tesoro, Atwood Oceanics, and Massey Energy. Tesoro is a leading refiner and marketer of petroleum products whose sales and earnings are benefiting from strong fundamentals in the energy industry. Atwood Oceanics is an oil and natural gas contract driller. Massey Energy is a well-positioned coal producer. In the consumer discretionary sector, we added American Eagle Outfitters and Las Vegas Sands to the Fund. American Eagle is a mall-based specialty retailer of men's and women's casual apparel, footwear, and accessories. The company has enjoyed healthy same-store sales trends nationwide. Las Vegas Sands has benefited from the growing popularity of Las Vegas as a vacation destination. WHICH STOCKS DID THE FUND SELL DURING THE REPORTING PERIOD? We sold the Fund's positions in First Marblehead, Pacific Sunwear of California, Acxiom, Maverick Tube, and Claire's Stores, all of which detracted from the Fund's performance. During the reporting period, we also eliminated the Fund's position in St. Jude Medical, a provider of implantable medical devices, because the company's shares grew beyond the Fund's capitalization parameters. We sold the Fund's position in credit-card company First Providian after an offer from Washington Mutual at a substantial premium caused a surge in First Providian's share price. We sold Doral Financial and Patterson Companies because of rapidly deteriorating business fundamentals. HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD? The Fund increased its exposure to the energy sector during the reporting period. Over the same period, we increased the Fund's allocation to the materials sector. During the reporting period, the Fund decreased its weightings in the consumer discretionary, health care, and information technology sectors. www.MAINSTAYfunds.com 9 HOW DO THE FUND'S WEIGHTINGS COMPARE WITH THOSE OF THE RUSSELL MIDCAP(R) GROWTH INDEX? As of October 31, 2005, the Fund was overweighted relative to the Russell Midcap(R) Growth Index in the consumer discretionary, energy, financials, health care, and materials sectors. At the same time, the Fund was underweighted relative to the Index in the industrials and information technology sectors. At the end of the reporting period, the Fund had no holdings in the consumer staples, telecommunications services, or utilities sectors.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Mid Cap Growth Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Distribution of Class A shares, Class B shares and Class C shares commenced on January 2, 2001. Class A shares are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Distribution of Class I shares commenced on March 29, 2005. Class I shares are not subject to sales charge. Class A shares, Class B shares, Class C shares and Class I shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions. Each class of shares other than Class I shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution or service fee. The Fund's investment objective is to seek long-term growth of capital. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices are normally taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 7). (C) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. 20 MainStay Mid Cap Growth Fund The following table discloses the current year reclassifications between net investment loss and additional paid-in-capital arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> ADDITIONAL PAID-IN NET INVESTMENT LOSS CAPITAL $1,422,180 $(1,422,180) - --------------------------------------------------- </Table> The reclassification for the Fund is due to the fact that net operating losses cannot be carried forward for federal income tax purposes. (E) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (F) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (G) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (H) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.75% on assets up to $500 million and 0.70% on assets in excess of $500 million. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.50% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $64,788 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005, the Manager had voluntarily agreed to reimburse the expenses of the Fund so that total operating expenses would not exceed, on an annualized basis, 1.50%, of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $828,019 and waived its fees and/or reimbursed expenses in the amount of $144,183. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of 0.375% www.MAINSTAYfunds.com 21 NOTES TO FINANCIAL STATEMENTS (CONTINUED) of the average daily net assets of the Fund. To the extent the manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, other than Class I shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $74,749 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $5,797, $58,470 and $2,789, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund, for the year ended October 31, 2005, amounted to $442,768. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. (F) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $3,024 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $37,707 for the year ended October 31, 2005. NOTE 4--CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, The Bank of New York acted as custodian for the Fund. NOTE 5--FEDERAL INCOME TAX: As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> ACCUMULATED TOTAL CAPITAL AND UNREALIZED ACCUMULATED OTHER LOSSES APPRECIATION LOSS $(2,604,998) $32,870,922 $30,265,924 - ---------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to wash sale loss deferrals. At October 31, 2005, for federal income tax purposes, capital loss carryforwards of $2,604,998 were available as shown in the table below, to the extent provided by the regulations to offset future realized gains of the Fund 22 MainStay Mid Cap Growth Fund through the years indicated. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to shareholders. <Table> <Caption> CAPITAL LOSS AMOUNT AVAILABLE THROUGH (000'S) 2011 $2,605 - --------------------------------------------------- </Table> The Fund utilized $7,836,185 of capital loss carryforwards during the year ended October 31, 2005. NOTE 6--PURCHASES AND SALES OF SECURITIES (IN 000'S): During the year ended October 31, 2005, purchases and sales of securities, other than short-term securities, were $65,773 and $47,319, respectively. NOTE 7--PORTFOLIO SECURITIES LOANED: As of October 31, 2005, the Fund had securities on loan with an aggregate market value of $22,009,555. The Fund received $22,699,733 in cash as collateral for securities on loan which was used to purchase highly liquid short-term investments in accordance with the Fund's securities lending procedures. Pursuant to Rule 2a-7, securities purchased with collateral received are valued at amortized cost. NOTE 8--LINE OF CREDIT: The Fund and certain affiliated funds maintain a line of credit of $160,000,000 with a syndicate of banks in order to secure a source of funds for temporary purposes to meet unanticipated or excessive shareholder redemption requests. The funds pay a commitment fee, at an annual rate of .075% of the average commitment amount, regardless of usage, to The Bank of New York, which acts as agent to the syndicate. Such commitment fees are allocated among the funds based upon net assets and other factors. Interest on any revolving credit loan is charged based upon the Federal Funds Advances rate. There were no borrowings on the line of credit during the year ended October 31, 2005.

NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay Mid Cap Growth Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 23 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Mid Cap Growth Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Mid Cap Growth Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 24 MainStay Mid Cap Growth Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's top decile performance over recent time periods and its top quartile performance since inception when compared with funds concluded by Trustees to be peers of the Fund. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual 28 MainStay Mid Cap Growth Fund breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund were among the highest of The MainStay Funds, and that transfer agency fees of a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 29 PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that New York Life Investment Management LLC ("NYLIM") uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by calling 1-800-MAINSTAY (1-800-624-6782); (ii) by visiting the Fund's website at www.mainstayfunds.com; or (iii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ Christopher O. Blunt Christopher O.

Total returns reflect change in share price and reinvestment of dividend and capital-gain distributions. Class A, B, and C shares are sold with no initial sales charge or contingent deferred sales charge (CDSC) and have no annual 12b-1 fees. Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. The fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. From inception (5/1/86) through 12/31/94 (for Class A, first offered 1/3/95) and 8/31/98 (for Class C, first offered 9/1/98), performance of Class A and Class C shares includes the historical performance of Class B shares. 1. As of 10/31/05, MainStay Money Market Fund had an effective 7-day yield of 3.23% and a 7-day current yield of 3.16% for Class A, B, and C shares. These yields reflect certain expense limitations. Had these expense limitations not been in effect, the effective 7-day yield would have been 2.97% and the current 7-day yield would have been 2.91%. The fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The current yield is more reflective of the Fund's earnings than the total return. 2. Lipper Inc. is an independent fund performance monitor.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1, through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,013.70 $3.55 $1,021.50 $3.57 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,013.70 $3.55 $1,021.50 $3.57 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,013.70 $3.55 $1,021.50 $3.57 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

The Fund invests in high-quality, short-term securities that are denominated in U.S. dollars and mature in 13 months or less. The dollar-weighted average maturity of the Fund's investment portfolio will not exceed 90 days. The Fund's portfolio may include obligations issued or guaranteed by the U.S. government or any of its agencies or instrumentalities. The Fund may also invest in bank and bank holding company obligations, such as CDs and bankers' acceptances. The Fund may own commercial paper, which consists of short-term, unsecured loans to corporations; corporate debt securities; loans to U.S. and foreign issuers and securities of foreign branches of U.S. and foreign banks, such as negotiable CDs, also known as Eurodollars; time deposits; and repurchase agreements. We may sell a security if changes in the economy, the financial situation of the issuer, the condition and outlook of the issuer's industry, or other factors lead us to believe that the security will not contribute to meeting the Fund's investment objective. WHAT WAS THE ECONOMIC AND INTEREST-RATE ENVIRONMENT DURING THE REPORTING PERIOD? According to recent data, the U.S. economy grew at an average rate of 3.7% during the four quarters ended September 30, 2005. Despite damage to the Gulf Coast states from hurricanes Katrina and Rita in the late summer and early autumn, the economy managed to grow at a seasonally adjusted annual rate of 4.3% during the third calendar quarter of 2005, according to preliminary estimates from the Bureau of Economic Analysis. The Federal Open Market Committee met eight times during the 12 months ended October 31, 2005, and raised the targeted federal funds rate 25 basis points at each meeting. (A basis point is one-hundredth of a percentage point.) These eight rate hikes brought the targeted federal funds rate to 3.75% at the end of October 2005. From October 29, 2004, to October 31, 2005, three-month Treasury-bill yields rose from 1.89% to 3.89%, while three-month LIBOR increased from 2.17% to 4.26%.(1) HOW DID THE FUND INVEST DURING THE REPORTING PERIOD? The Fund performed well relative to its peers for the 12 months ended October 31, 2005. Details of the Fund's performance and appropriate disclosure can be found on page 4 of this report. The Fund's portfolio contained securities issued by the U.S. Treasury and government-sponsored agencies. The Fund also held securities issued by finance, insurance, brokerage, and industrial companies, as well as banks and bank holding companies. These were first-tier securities, or generally those money market instruments in the highest-rated category. As of October 31, 2005, the average maturity of the Fund was approximately 54 days. AN INVESTMENT IN THE FUND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE FUND SEEKS TO PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00 PER SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. 1. Source: Bloomberg--Historical yield curve data.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Money Market Fund (the "Fund"), a diversified fund. The Fund currently offers three classes of shares. Class A shares, Class B shares and Class C shares whose distributions commenced on January 3, 1995, May 1, 1986 and September 1, 1998, respectively. The shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions. The Fund's investment objective is to seek as high a level of current income as is considered consistent with the preservation of capital and liquidity. The Fund's principal investments include derivatives such as variable rate master demand notes, "floating-rate notes" and mortgage-related and asset-backed securities. If expectations about change in interest rates, or assessments of an issuer's credit worthiness or market conditions are wrong, the use of derivatives or other investments could result in a loss. The Fund also invests in foreign securities which carry certain risks in addition to the usual risks inherent in domestic instruments. These risks include those resulting from future adverse political and economic developments and possible imposition of currency exchange blockages or other foreign governmental laws and restrictions. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country, industry or region. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) VALUATION OF FUND SHARES. The Fund seeks to maintain a net asset value of $1.00 per share, although there is no assurance that it will be able to do so on a continuous basis, and it has adopted certain investment, portfolio and dividend and distribution policies designed to enable it to do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. (B) SECURITIES VALUATION. Pursuant to Rule 2a-7 securities are valued at their amortized cost. The amortized cost method involves valuing a security at its cost on the date of purchase and thereafter assuming a constant amortization to maturity of the difference between such cost and the value on maturity date. (C) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. (D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. Dividends are declared daily and paid monthly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from generally accepted accounting principles. (E) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Interest income is accrued daily and discounts and premiums on securities purchased for the Fund are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (F) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (G) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (H) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. 16 MainStay Money Market Fund Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.50% on assets up to $300 million, 0.45% on assets from $300 million to $700 million, 0.40% on assets from $700 million to $1.0 billion and 0.35% on assets in excess of $1.0 billion. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 0.70% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $232,330 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005, the Manager had agreed to voluntarily reimburse the expenses of the Fund so that total annual fund operating expenses do not exceed on an annualized basis 0.70% of the average daily net assets of each class of shares of the Fund. For the year ended October 31, 2005, the Manager earned from the Fund $2,328,595, and waived its fees and/or reimbursed expenses in the amount of $1,379,735. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of the Fund's average daily net assets of 0.25% on assets up to $300 million, 0.225% on assets from $300 million to $700 million, 0.20% on assets from $700 million to $1 billion and 0.175% on assets in excess of $1 billion. To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) CONTINGENT DEFERRED SALES CHARGE. Although the Fund does not assess a contingent deferred sales charge upon redemption of Class B or Class C shares of the Fund, the applicable contingent deferred sales charge will be assessed when shares were redeemed from the Fund if the shareholder previously exchanged his or her investment into the Fund from another Fund in the Trust. The Fund was advised that NYLIFE Distributors LLC (the "Distributor"), an indirect wholly owned subsidiary of New York Life, received from shareholders the proceeds from contingent deferred sales charges for the year ended October 31, 2005, in the amount of $1,340,992. (C) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses for the year ended October 31, 2005, amounted to $1,924,785. (D) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. www.MAINSTAYfunds.com 17 NOTES TO FINANCIAL STATEMENTS (CONTINUED) (E) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $12,749 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $75,081 for the year ended October 31, 2005. NOTE 4--CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, State Street Bank and Trust Company acted as custodian for the Fund. NOTE 5--FEDERAL INCOME TAX: At October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> UNDISTRIBUTED ACCUMULATED OTHER TOTAL ORDINARY NET REALIZED TEMPORARY ACCUMULATED INCOME LOSS DIFFERENCES LOSS $56,142 $ (5,053) $(56,142) $(5,053) -------------------------------------------------------- </Table> At October 31, 2005, for federal income tax purposes capital loss carryforwards of $5,053 were available as shown in the table below, to the extent provided by the regulations to offset future realized gains through the years indicated. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to shareholders. <Table> <Caption> CAPITAL LOSS AMOUNT AVAILABLE THROUGH (000) 2013 $5 - ------------------------------------------------ </Table> Dividends to shareholders from net investment income and distributions from net realized gains shown in the Statement of Changes in Net Assets represent tax basis distributions of ordinary income.

NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to agreements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay Money Market Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter, and has paid substantially all of the costs associated with the other regulatory matters described in this note. 18 MainStay Money Market Fund In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 19 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Money Market Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Money Market Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 20 MainStay Money Market Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's mid-range performance over various periods of time relative to funds concluded by Trustees to be peers of the Fund. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the 24 MainStay Money Market Fund Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees noted that the Fund's contractual management fee had been reduced in accordance with the terms of the breakpoint schedule applicable to the Fund. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 25 PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that New York Life Investment Management LLC ("NYLIM") uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by calling 1-800-MAINSTAY (1-800-624-6782); (ii) by visiting the Fund's website at www.mainstayfunds.com; or (iii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ Christopher O. Blunt Christopher O.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT VALUE ENDING ACCOUNT (BASED ON VALUE (BASED HYPOTHETICAL BEGINNING ON ACTUAL EXPENSES 5% RETURN EXPENSES ACCOUNT RETURNS AND PAID AND ACTUAL PAID VALUE EXPENSES) DURING EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,001.75 $4.49 $1,020.55 $4.53 - -------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,000.50 $5.75 $1,019.30 $5.80 - -------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,000.50 $5.75 $1,019.30 $5.80 - -------------------------------------------------------------------------------------------------------------------------- </Table> 1.

The Fund normally invests in U.S. tax-exempt securities of any maturity that are, at the time of purchase, rated in one of the top four categories (or in short-term tax-exempt securities rated in one of the top three categories) by Moody's or S&P. Not more than 20% of the Fund's net assets may be invested in unrated tax-exempt securities that we deem to be of comparable quality. The Fund normally invests at least 80% of its net assets in municipal bonds. In implementing this strategy, we use a combined approach to investing that analyzes economic trends and factors pertinent to particular issuers and securities. WHAT ECONOMIC FORCES AFFECTED THE BOND MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? Throughout the reporting period, the bond market was torn on the question of how higher energy costs would affect the economy as a whole. Either high energy costs would raise inflation expectations or such costs would tend to reduce aggregate demand. Toward the end of the reporting period, the consensus appeared to shift toward the former opinion. In mid-September, the Federal Open Market Committee's commentary crystallized this view. At the same time, the FOMC raised the targeted federal funds rate to 3.75% in its eighth 25-basis-point move during the reporting period. (A basis point is one-hundredth of a percentage point.) Despite widespread concern that hurricanes Katrina and Rita might derail trend growth in the economy, the Federal Reserve saw rebuilding activity as potentially stimulative. As a result, we anticipate additional interest-rate hikes from the Federal Open Market Committee through the first quarter of 2006. At the end of October, the Eurodollar futures market was evenly split, anticipating either a 4.25% or a 4.50% targeted federal funds rate by March 31, 2006. HOW DID THESE FACTORS AFFECT MUNICIPAL BONDS? Inflation is the bane of the bond market, so not surprisingly, municipal yields rose during the 12-month reporting period. Two-year municipal yields rose from 2.7% to 3.1%, five-year municipals advanced from 3.1% to 3.4%, 10-year municipals climbed from 3.6% to 3.9%, and 30-year municipal yields rose from 4.4% to 4.6%. Federal Reserve policy directives hastened this fairly substantial move. As these changes imply, the municipal yield curve did not shift uniformly. Instead, the yield curve flattened as the spread(1) between two-year and 30- year municipal bond yields narrowed 20 basis points. WHAT WAS THE FUND'S DURATION STRATEGY DURING THE REPORTING PERIOD? From November 2004 through July 2005, we kept the Fund's duration shorter than that of the Lehman Brothers(R) Municipal Bond Index.(2) Our positioning expressed our bearish interest-rate outlook amid firm economic data and the Federal Open Market Committee's resolve to steadily move targeted federal funds rate higher. In August 2005, we lengthened the Fund's duration to a neutral position relative to the benchmark as yields rose to more attractive levels. WHAT POSITIONING DECISIONS SIGNIFICANTLY AFFECTED THE FUND'S PERFORMANCE? An overweighted position in the housing sector helped the Fund's performance during the reporting period as yield-starved investors gravitated toward sectors that offered attractive yields relative to high-grade municipal bonds. The housing-revenue-bond component of the Lehman Brothers(R) Municipal Bond Index outperformed the Index as a whole by 91 basis points. On the other hand, the Fund's underweighted exposure to the tobacco-settlement-bond component of the Lehman Brothers(R) Municipal Bond Index detracted from performance because the tobacco-settlement-bond component of the Lehman Brothers(R) Municipal Bond Index outperformed the Index by 1,778 basis points (or 17.78 percentage points). The Fund's tobacco-sector weighting at the start of the reporting period was 1.0%, which we reduced to 0% in February 2005. Two-percent of the Lehman Brothers(R) Municipal Bond Index is made up of tobacco-sector bonds. Relative to high-grade municipals, tobacco spreads tightened to their narrowest risk premiums in two years. We expect this trend to reverse, since several issuers want to take advantage Funds that invest in bonds are subject to interest rate, credit, and inflation risk and can lose principal value when interest rates rise. A portion of income may be subject to state and local taxes or the alternative minimum tax. The Fund may invest in derivatives, which may increase the volatility of the Fund's net asset value and may result in a loss to the Fund. 1. The terms "spread" and "yield spread" may refer to the difference in yield between a specific security or type of security and comparable U.S. Treasury issues. The terms may also refer to the difference in yield between two specific securities or types of securities at a given time. 2. See footnote on page 5 for more information on the Lehman Brothers(R) Municipal Bond Index. 8 MainStay Tax Free Bond Fund of the narrow risk spreads and have announced plans to market new issues. During the reporting period, several of the Fund's holdings were prerefunded in Treasury securities. Such transactions may allow issuers to reduce overall borrowing costs by issuing new securities at current market rates and retiring old, higher-coupon issues.(3) These refundings helped the Fund's performance. While many of the Fund's eligible securities have already been refunded, we have maintained the Fund's positions in several other issues that could also be refunded if municipal yields were to revisit the low levels seen in February or June of 2005. ARE STATE BUDGET DEFICITS STILL AN ISSUE FOR THE MUNICIPAL MARKET? An improving economy has continued to strengthen state finances. According to the Rockefeller Institute of Government, state tax revenue grew 13.3% in the second calendar quarter of 2005 compared to the first calendar quarter--the fastest growth since the Institute began tracking revenues in 1991. This broad-based increase was seen across all three major sources of revenue: personal income tax, corporate income tax, and general sales tax. The opinions expressed are those of the portfolio managers as of the date of this report and are subject to change. There is no guarantee that any forecasts made will come to pass. This material does not constitute investment advice and is not intended as an endorsement of any specific investment. 3. Advance refunding allows a bond issuer to float a second bond at a lower interest rate and to invest the proceeds from the sale of the second bond safely (usually in Treasury securities) to collateralize the first bond. Since advance-refunded bonds become the equivalent of fully tax-exempt U.S. Treasury securities and no longer represent the credit risk profile of the original borrower, they often increase in value--sometimes significantly.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Tax Free Bond Fund (the "Fund"), a diversified fund. The Fund currently offers three classes of shares. Class A shares, whose distribution commenced on January 3, 1995, are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Distribution of Class B shares and Class C shares commenced on May 1, 1986 and September 1, 1998, respectively. Class A shares, Class B and Class C shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions except that the Class B shares and Class C shares are subject to higher distribution fee rates. Each class of shares bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. The Fund's investment objective is to provide a high level of current income free from regular federal income tax, consistent with the preservation of capital. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic developments in a specific industry or region. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Debt securities are valued at prices supplied by a pricing agent or brokers selected by the Fund's Manager, whose prices reflect broker/dealer supplied valuations and electronic data processing techniques, if such prices are deemed by the Fund's Manager to be representative of market values, at the regular close of business of the New York Stock Exchange. Futures contracts are valued at the last posted settlement price on the market where such futures are principally traded. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. At October 31, 2005, the Fund did not hold securities that were valued in such a manner. (B) FUTURES CONTRACTS. A futures contract is an agreement to purchase or sell a specified quantity of an underlying instrument at a specified future date and price, or to make or receive a cash payment based on the value of a securities index. During the period the futures contract is open, changes in the value of the contract are recognized as unrealized gains or losses by "marking to market" such contract on a daily basis to reflect the market value of the contract at the end of each day's trading. The Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as "variation margin". When the futures contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. The Fund may enter into contracts for the future delivery of debt securities in order to attempt to protect against the effect of adverse changes in interest rates, to lengthen or shorten the average maturity or duration of the Fund's portfolio or to try to enhance the Fund's returns. The use of futures contracts involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statement of Assets and Liabilities. The contract or notional amounts and variation margin reflect the extent of the Fund's involvement in open futures positions. Risks arise from the possible imperfect correlation in movements in the price of futures contracts, interest rates and the underlying hedged assets, and the possible inability of counterparties to meet the terms of their contracts. However, the Fund's activities in futures contracts are conducted through regulated exchanges which minimize counterparty credit risks. (C) PURCHASED AND WRITTEN OPTIONS. The Fund may write covered call and put options on its portfolio securities or foreign currencies. Premiums are received and are recorded as liabilities. The liabilities are subsequently adjusted and unrealized appreciation or depreciation is recorded to reflect the current value of the options written. Premiums received from writing options which expire are 20 MainStay Tax Free Bond Fund treated as realized gains. Premiums received from writing options which are exercised or are cancelled in closing purchase transactions are added to the proceeds or netted against the amount paid on the transaction to determine the realized gain or loss. By writing a covered call option, in exchange for the premium, the Fund foregoes the opportunity for capital appreciation above the exercise price should the market price of the underlying security or foreign currency increase but, as long as the obligation as a writer continues, have retained the risk of loss should the price of the underlying security decline. By writing a covered put option, the Fund, in exchange for the premium, accepts the risk of decline in the market value of the underlying security or foreign currency below the exercise price. After writing a put option, the Fund may incur a loss equal to the difference between the exercise price of the option and the sum of the market value of the underlying security plus the premium received from the sale of the option. A call option may be covered by the call writer's owning the underlying security throughout the option period. A call option may also be covered by the call writer's maintaining liquid assets valued at greater than the exercise price of the call written, in a segregated account with its custodian. The Fund may purchase call and put options on its portfolio securities. The Fund may purchase call options to protect against an increase in the price of the security it anticipates purchasing. The Fund may purchase put options on its securities to protect against a decline in the value of the security or to close out covered written put positions. The Fund may also purchase options to seek to enhance returns. Risks may arise from an imperfect correlation between the change in market value of the securities held by the Fund and the prices of options relating to the securities purchased or sold by the Fund and from the possible lack of a liquid secondary market for an option. The maximum exposure to loss for any purchased option is limited to the premium initially paid for the option. (D) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable and non-taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. (E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends monthly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. (F) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Interest income is accrued as earned. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (G) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (H) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (I) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. www.MAINSTAYfunds.com 21 NOTES TO FINANCIAL STATEMENTS (CONTINUED) NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.60% on assets up to $1.0 billion and 0.55% on assets in excess of $1.0 billion. NYLIM has agreed to waive its management fee by 0.15% to 0.45% (effective August 1, 2004). Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 0.89% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $30,280 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM agreed to voluntarily reimburse the expenses of the Fund so that total annual fund operating expenses would not exceed on an annualized basis 0.89% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $1,740,637 and waived its fee and/or reimbursed expenses in the amount of $504,934. Pursuant to the terms of a Sub-Advisory Agreement between the NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of 0.30% of the average daily net assets of the Fund. To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.25% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $32,113 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $423, $72,168 and $1,263, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $289,465. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage 22 MainStay Tax Free Bond Fund and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. (F) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $7,443 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $55,677 for the year ended October 31, 2005. NOTE 4--CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, State Street Bank and Trust Company acted as custodian for the Fund. NOTE 5--FEDERAL INCOME TAX: The Fund has maintained a year end of December 31 for federal income tax purposes. At October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> UNDISTRIBUTED ACCUMULATED OTHER TOTAL TAX EXEMPT CAPITAL TEMPORARY UNREALIZED ACCUMULATED INCOME LOSSES DIFFERENCES APPRECIATION LOSS $31,029 $ (32,045,133) $(293,503) $12,883,864 $(19,423,743) ------------------------------------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to the tax treatment of futures transactions. At October 31, 2005, for federal income tax purposes, capital loss carryforwards of $32,045,133 were available, as shown in the table below, to the extent provided by the regulations, to offset future realized gains through the years indicated. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to shareholders. <Table> <Caption> CAPITAL LOSS AMOUNTS AVAILABLE THROUGH (000'S) 2007 $ 7,997 2008 15,453 2011 8,117 2012 478 ------------------------------------------- $32,045 ------------------------------------------- </Table> Dividends to shareholders from net investment income, shown in the Statement of Changes in Net Assets, represents tax-based distributions of tax exempt income.

NOTE 7 -- LINE OF CREDIT: The Fund and certain affiliated funds maintain a line of credit of $160,000,000 with a syndicate of banks in order to secure a source of funds for temporary purposes to meet unanticipated or excessive shareholder redemption requests. The funds pay a commitment fee, at an annual rate of .075% of the average commitment amount, regardless of usage, to The Bank of New York, which acts as agent to the syndicate. Such commitment fees are allocated among the funds based upon net assets and other factors. Interest on any revolving credit loan is charged based upon the Federal Funds Advances rate. There were no borrowings on the line of credit during the year ended October 31, 2005.

NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay Tax Free Bond Fund was $50,000. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance at this time as to the outcome of these efforts. 24 MainStay Tax Free Bond Fund REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Tax Free Bond Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Tax Free Bond Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 www.MAINSTAYfunds.com 25 TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's underperformance when compared over several time periods with funds concluded by Trustees to be peers of the Fund, and the Manager's and Subadvisor's agreement to monitor performance closely in consultation with the Board. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from econo- www.MAINSTAYfunds.com 29 mies of scale arising from the growth of Fund assets. The Trustees acknowledged that the Fund had not yet reached the asset level at which breakpoints would reduce the contractual management fee to which the Fund is subject. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses and received information about potential effects on the Manager were it to subsidize certain portions of the transfer agency fees of the other series of the Trust. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. 30 MainStay Tax Free Bond Fund FEDERAL INCOME TAX INFORMATION--UNAUDITED For Federal individual income tax purposes, the fund hereby designates 100% of the ordinary income dividends paid during its fiscal year ended October 31, 2005 as attributable to interest income from Tax Exempt Municipal Bonds.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,057.55 $ 6.17 $1,019.05 $6.06 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,053.70 $10.04 $1,015.30 $9.85 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,053.10 $10.04 $1,015.30 $9.85 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,066.10 $ 4.48 $1,020.70 $4.38 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Carryl, Edmund C. Spelman, Richard A. Rosen, Gary Goodenough, and Christopher Harms of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests a minimum of 30% of its assets in U.S. equity securities and a minimum of 30% in U.S. debt securities. In implementing this investment strategy, about half of the equity portion of the Fund's portfolio is invested in growth-oriented stocks and about half in stocks that the Fund believes to be undervalued. In addition to holding investment-grade bonds, the bond portion of the Fund's portfolio may purchase high-yield bonds and other debt securities rated below investment grade that we believe may provide capital appreciation in addition to income. The stock and bond portions of the Fund's portfolio may both take a flexible approach by investing in a variety of securities, industries, and issues. WHAT MAJOR FACTORS AFFECTED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? During the 12 months ended October 31, 2005, stocks generally advanced, with value stocks outperforming growth stocks at all capitalization levels. Arguably the biggest factor influencing the equity market during the reporting period was the substantial rise in the price of crude oil, which continued an upward trend that began in the previous year. Major hurricanes affected supply-and-demand dynamics by damaging oil rigs and petrochemical plants. The price of gasoline rose to more than $3 a gallon, which threatened to slow consumer spending. Despite these setbacks, recent gross-domestic-product data suggest that the overall economy has remained resilient. On the geopolitical front, negative headlines about progress in Iraq also weighed heavily on investors' minds throughout the reporting period. WHAT MAJOR DECISIONS AFFECTED PERFORMANCE IN THE EQUITY PORTION OF THE FUND'S PORTFOLIO? The Fund invests in growth and value stocks. The growth-equity component of the Fund's portfolio benefited from effective health care stock selection and from overweighted positions in energy and consumer discretionary stocks. Energy stocks also made positive contributions in value-equity component of the Fund's portfolio. Value-oriented financial holdings showed strength, while growth-oriented financial stocks were neutral. In the growth-equity component, industrial stocks detracted from performance. And while the Fund owned no telecommunication services growth stocks, the equity portion of the Fund's portfolio did well with its value holdings in the sector. WHICH INDIVIDUAL STOCKS PROVIDED STRONG PERFORMANCE DURING THE REPORTING PERIOD? Among the Fund's growth equities, strong performers included coal provider Peabody Energy, which rose on strong demand; Apple Computer, which advanced on the popularity of the iPod; pharmacy benefit manager Caremark Rx, which generated higher earnings; UnitedHealth Group, which saw strong demand and pricing power in the health services sector; and biotechnology company Genentech, which advanced on strong earnings and a dynamic new product pipeline. Among the Fund's value stocks, energy-related holdings Transocean, Pride International, ENSCO International, and Rowan all advanced on higher energy prices and strong demand. We trimmed several of these positions as the stocks approached our price targets. Among value-oriented financial stocks, operating improvements at Prudential Financial led to excellent returns, and the Fund saw strong results from Hartford Financial Securities Group, St. Paul Travelers, and AFLAC. During the reporting period Motorola, Texas Instruments, Kroger, and Cadbury Schweppes were among the Fund's other strong value holdings. WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? In the Fund's growth-equity component, Maxim Integrated Products, an integrated-circuit manufacturer, declined on heightened competition and a shift in the company's product focus. Internet-auction giant eBay fell on slowing growth in European markets and softening volume in the United States. Shares of Brunswick, known for its boats, marine engines, and equipment for fitness, billiards, and bowling, fell when the company lowered earnings estimates. Harman International Industries, whose audio product sales are tied to automotive markets, provided disappointing earnings guidance and faced competitive challenges. Motorcycle manufacturer Harley-Davidson lowered production guidance for the first time in the company's history. Sales, earnings, and profit projections were also adjusted, which took a toll on the company's shares. High-yield securities ("junk bonds") are generally considered speculative because they present a greater risk of loss than higher-quality debt securities and may be subject to greater price volatility. The Fund may invest in derivatives, which may increase the volatility of the Fund's net asset value and may result in a loss to the Fund. 8 MainStay Total Return Fund Among the Fund's value stocks, The Gap's shares declined when the fall season got off to a slower-than-expected start. Pharmaceutical giant Pfizer suffered from pending generic-drug litigation and weaker-than-expected guidance for 2006. Nevertheless, we like the stock and have hedged nearly all of the Fund's position using protective put contracts to limit downside exposure. Aluminum manufacturer Alcoa faced contracting margins, and glass manufacturer Owens-Illinois was hurt by higher costs. We sold the Fund's entire positions in these stocks. Verizon Communications faced stronger competition but continued to provide a high dividend yield. We used the stock's lower valuation to add to the Fund's position late in the reporting period. WERE THERE ANY OTHER SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? In the spring of 2005, we sold the Fund's entire positions in several growth-oriented technology stocks, including Applied Materials, KLA Tencor, Cisco Systems, and Hewlett-Packard, and we redeployed the proceeds in other information technology names, including Corning, EMC, Apple Computer, Intel, and Texas Instruments. In the value-equity component, we purchased Molson Coors Brewing but later sold the position when the company was unable to overcome merger-integration difficulties and the price continued to decline. Although we bought shares of printer manufacturer Lexmark at a price that we felt was low, operating problems and inventory issues led us to sell the Fund's position at a loss in late October. WHAT ECONOMIC FORCES AFFECTED THE BOND MARKET DURING THE REPORTING PERIOD? Debate over the lasting effects of higher energy costs continued, with aggregate demand and inflation among the key concerns. Noting that "higher energy and other costs have the potential to add to inflation pressures," the Federal Open Market Committee raised the targeted federal funds rate to 3.75% on September 20, 2005. The move was the FOMC's eighth 25-basis-point increase during the 12-month reporting period. (A basis point is one-hundredth of a percentage point.) HOW DID THE TREASURY YIELD CURVE CHANGE DURING THE REPORTING PERIOD? From October 29, 2004, to October 31, 2005, the two-year Treasury yield advanced from 2.56% to 4.38%. Over the same period, five-year Treasury yields increased from 3.29% to 4.45% and 10-year Treasury yields rose from 4.03% to 4.56%. On the other hand, 30-year Treasury yields, declined from 4.79% to 4.75%.(1) Strong inflows from Asian central banks helped support prices among longer-dated Treasurys and resulted in a substantial flattening of the yield curve during the reporting period. We have positioned the bond portion of the Fund to take advantage of this flattening trend. WHAT ELSE DID YOU DO TO POSITION THE BOND PORTION OF THE FUND IN THIS ENVIRONMENT? During the 12-month reporting period, the bond portion of the Fund sought to benefit from the yield advantages of positions in moderate- and lower-quality securities. Specifically, we sought exposure to issuers in oil-rich emerging economies. We also used rigorous credit analysis to help reduce the chances that the bond portion of the Fund's portfolio would fall prey to negative credit events. We positioned the bond portion of the Fund's portfolio quite differently than we did a year ago, when we were seeking credit risk to increase incremental returns. The new positioning sought a better balance between interest-rate risk and credit risk, particularly since compensation for taking on additional credit risk remained modest. HOW HAS THE MAKEUP OF THE BOND PORTION OF THE FUND'S PORTFOLIO CHANGED DURING THE REPORTING PERIOD? During the reporting period, the bond portion of the Fund reduced its allocation to investment-grade and high-yield corporate bonds to acknowledge their relatively low yields. The proceeds were split among Treasurys, agency debentures, mortgage-backed securities, and cash equivalents. HOW WAS THE BOND PORTION OF THE FUND INVESTED AT THE END OF THE REPORTING PERIOD? As of October 31, 2005, we positioned the bond portion of the Fund's portfolio with a larger-than-usual cash position. The cash was needed to balance the Fund's longer-duration securities, which reflected our yield-curve flattening bias. In addition, the duration of the bond portion of the Fund's portfolio was close to--but slightly shorter than--the duration of the Lehman Brothers(R) Aggregate Bond Index. With a shorter duration, the Fund should be less sensitive than the Index to changes in interest rates. (The Lehman Brothers(R) Aggregate Bond Index is the bond component of the Fund's custom benchmark.) 1. Source: Bloomberg -- Historical yield curve data. www.MAINSTAYfunds.com 9 At the end of October, the bond portion of the Fund's portfolio was overweighted relative to the Lehman Brothers Aggregate Bond Index in high-yield corporate bonds, asset-backed securities, mortgage-backed securities, and cash equivalents. The bond portion of the Fund was underweighted relative to the Index in Treasurys, investment-grade corporate bonds, and agency debentures.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Total Return Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Class A shares, whose distribution commenced on January 3, 1995, are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Distribution of Class B shares and Class C shares commenced on December 29, 1987 and September 1, 1998, respectively. Class I shares are not subject to a sales charge. Distribution of Class I shares commenced on January 2, 2004. Class A shares, Class B shares, Class C shares and Class I shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions. Each class of shares, other than Class I shares, bears distribution and/or service fee payments under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution or service fee. The Fund's investment objective is to realize current income consistent with reasonable opportunity for future growth of capital and income. The Fund also invests in foreign securities which carry certain risks that are in addition to the usual risks inherent in domestic instruments. These risks include those resulting from currency fluctuations, future adverse political and economic developments and possible imposition of currency exchange blockages or other foreign governmental laws or restrictions. These risks are likely to be greater in emerging markets than in developed markets. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country, industry or region. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Debt securities are valued at prices supplied by a pricing agent or brokers selected by the Fund's Manager, whose prices reflect broker/dealer supplied valuations and electronic data processing techniques, if such prices are deemed by the Fund's Manager to be representative of market values, at the regular close of business of the New York Stock Exchange. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. Certain events may occur between the time that foreign markets close, on which securities held by the Fund principally trade, and the time at which the Fund's NAV is calculated. These events may include, but are not limited to, situations relating to a single issue in a market sector, significant fluctuations in U.S. or foreign markets, natural disasters, armed conflicts, governmental actions or other developments not tied directly to the securities markets. Should the Manager or Subadvisor conclude that such events may have effected the accuracy of the last price reported on the local foreign market, the Manager or Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of the local price to reflect the impact on the price of such securities as a result of such events. (B) MORTGAGE DOLLAR ROLLS. The Fund enters into mortgage dollar roll ("MDR") transactions in which it sells mortgage-backed securities ("MBS") from its portfolio to a counterparty from whom it simultaneously agrees to buy a similar security on a delayed delivery basis. The MDR transactions of the Fund are classified as purchase and sale transactions. The securities sold in connection with the MDRs are removed from the portfolio and a realized gain or loss is recognized. The securities the Fund has agreed to 26 MainStay Total Return Fund acquire are included at market value in the portfolio of investments and liabilities for such purchase commitments are included as payables for investments purchased. During the roll period, a Fund forgoes principal and interest on the securities. A Fund is compensated by the difference between the current sales price and the forward price for the future purpose as well as by the earnings on the cash proceeds of the initial sale. MDRs may be renewed without physical delivery of the securities subject to the contract. The Fund maintains a segregated account with its custodian containing securities from its portfolio having a value not less than the repurchase price, including accrued interest. MDR transactions involve certain risks, including the risk that the MBS returned to the Fund at the end of the roll, while substantially similar, could be inferior to what was initially sold to the counterparty. (C) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 7.) (D) RESTRICTED SECURITIES. A restricted security is a security which has been purchased through a private offering and cannot be resold to the general public without prior registration under the Securities Act of 1933 (the "1933 Act"). The Fund does not have the right to demand that such securities be registered. Disposal of these securities may involve time-consuming negotiations and expense and prompt sale at an acceptable price may be difficult. (See Note 7.) (E) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS. The Fund invests in loan assignments and loan participations. Loan assignments and participations are agreements to make money available (a "commitment") to a borrower in a specified amount, at a specified rate and within a specified time. Such loan assignments and participations are typically senior, secured and collateralized in nature. The Fund records an investment when the borrower withdraws money and records interest as earned. These loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or London InterBank Offered Rate (LIBOR). The loans in which the Fund invests are generally readily marketable, but may be subject to some restrictions on resale. The Fund may be contractually obligated to receive approval from the agent bank and/or borrower prior to the sale of these investments. The Fund assumes the credit risk of the Borrower, the Selling Participant and any other persons interpositioned between the Fund and the Borrower ("Intermediate Participants"). In the event that the Borrower, Selling Participant or Intermediate Participants becomes insolvent or enters into bankruptcy, the Fund may incur certain costs and delays in realizing payment, or may suffer a loss of principal and/or interest. Unfunded commitments represent the remaining obligation of the Fund to the Borrower. At any point in time, up to the maturity date of the issue, the Borrower may demand the unfunded portion. These unfunded amounts are recorded in memorandum accounts. (F) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (G) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current year reclassification between accumulated undistributed net investment income, accumulated net realized gain and additional paid-in-capital, arising from permanent differences; net assets at October 31, 2005 are not affected. <Table> <Caption> ACCUMULATED NET UNDISTRIBUTED NET REALIZED GAIN ON ADDITIONAL INVESTMENT INCOME INVESTMENTS PAID-IN-CAPITAL $73,962 $(73,963) $1 ------------------------------------------------------ </Table> www.MAINSTAYfunds.com 27 NOTES TO FINANCIAL STATEMENTS (CONTINUED) The reclassifications for the Fund are primarily due to real estate investment trust investments, paydowns and foreign currency gain (loss). (H) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method and include gains and losses from repayments of principal on mortgage-backed securities. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on securities purchased, other than short-term securities, for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (I) PURCHASED AND WRITTEN OPTIONS. The Fund may write covered call and put options on its portfolio securities or foreign currencies. Premiums are received and are recorded as liabilities. The liabilities are subsequently adjusted and unrealized appreciation or depreciation is recorded to reflect the current value of the options written. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are cancelled in closing purchase transactions are added to the proceeds or netted against the amount paid on the transaction to determine the realized gain or loss. By writing a covered call option, in exchange for the premium, the Fund foregoes the opportunity for capital appreciation above the exercise price should the market price of the underlying security or foreign currency increase but, as long as the obligation as a writer continues, have retained the risk of loss should the price of the underlying security decline. By writing a covered put option, the Fund, in exchange for the premium, accepts the risk of decline in the market value of the underlying security or foreign currency below the exercise price. After writing a put option, the Fund may incur a loss equal to the difference between the exercise price of the option and the sum of the market value of the underlying security plus the premium received from the sale of the option. A call option may be covered by the call writer's owning the underlying security throughout the option period. A call option may also be covered by the call writer's maintaining liquid assets valued at greater than the exercise price of the call written, in a segregated account with its custodian. The Fund may purchase call and put options on its portfolio securities. The Fund may purchase call options to protect against an increase in the price of the security it anticipates purchasing. The Fund may purchase put options on its securities to protect against a decline in the value of the security or to close out covered written put positions. The Fund may also purchase options to seek to enhance returns. Risks may arise from an imperfect correlation between the change in market value of the securities held by the Fund and the prices of options relating to the securities purchased or sold by the Fund and from the possible lack of a liquid secondary market for an option. The maximum exposure to loss for any purchased option is limited to the premium initially paid for the option. (J) FOREIGN CURRENCY TRANSACTIONS. The books and records of the Fund are kept in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean between the buying and selling rates last quoted by any major U.S. bank at the following dates: (i) market value of investment securities, other assets and liabilities--at the valuation date, (ii) purchases and sales of investment securities, income and expenses--at the date of such transactions. The assets and liabilities are presented at the exchange rates and market values at the close of the period. The realized and unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. The unrealized changes in net assets arising from fluctuations in exchange rates and market prices of securities are not separately presented. Net realized gain (loss) on foreign currency transactions represents net gains and losses on foreign currency forward contracts, net currency gains or losses realized as a result of differences between the amounts of securities sale proceeds or purchase cost, dividends, interest and withholding taxes as recorded on the Fund's books, and the U.S. dollar equivalent amount actually received or paid. Net currency gains or losses from valuing such foreign currency denominated assets and liabilities, other than investments, are reflected in unrealized foreign exchange gains or losses at period end exchange rates. (K) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (L) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. 28 MainStay Total Return Fund (M) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.64% on assets up to $500 million and 0.60% on assets in excess of $500 million. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.19% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $177,401 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM agreed to voluntarily reimburse the expenses of the Fund so that total annual fund operating expenses would not exceed on an annualized basis 1.19% of the average daily net assets of the Class A and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $5,168,565 and waived its fees and/or reimbursed expenses in the amount of $975,313. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee of 0.32% of the average daily net assets of the Fund on assets up to $500 million and 0.30% on assets in excess of $500 million. To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION AND SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to each class of shares, other than Class I shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $306,171 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $4,835, $363,647 and $370, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $2,805,362. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 www.MAINSTAYfunds.com 29 NOTES TO FINANCIAL STATEMENTS (CONTINUED) for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non- Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. (F) CAPITAL. At October 31, 2005 New York Life held shares of Class A and Class I with net values of $5,360,090 and $1,090, respectively. This represents 5.5% and 14.6% of Class A and Class I net assets, respectively and 0.7% of the Fund's total net assets at October 31, 2005. (G) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $21,316 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $109,476 for the year ended October 31, 2005. NOTE 4--CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, State Street Bank and Trust Company acted as custodian for the Fund. NOTE 5--FEDERAL INCOME TAX: As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> ACCUMULATED CAPITAL TOTAL ORDINARY AND OTHER UNREALIZED ACCUMULATED INCOME GAINS APPRECIATION GAIN $2,494,629 $28,780,000 $71,016,480 $102,291,109 ------------------------------------------------------ </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to premium amortization adjustments and wash sale loss deferrals.

NOTE 10--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay Total Return Fund was $102,000. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 31 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Total Return Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Total Return Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 32 MainStay Total Return Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's underperformance when compared over several time periods with funds concluded by Trustees to be peers of the Fund, as well as changes to the Fund's investment process and its improving investment performance relative to those funds. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees, in considering economies of scale, reviewed information showing that the asset size of the Fund had decreased in size over the past five years. The Trustees discussed the extent to which economies of scale were 36 MainStay Total Return Fund projected by the Manager to be realized were the Fund to grow, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees noted that the Fund's contractual management fee had been reduced in accordance with the terms of the breakpoint schedule applicable to the Fund. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 37 FEDERAL INCOME TAX INFORMATION (UNAUDITED) The Fund is required by the Internal Revenue Code to advise shareholders within 60 days of the Fund's fiscal year end (October 31, 2005) as to the federal tax status of dividends paid by the Fund during such fiscal year.

The dividends paid by the Fund during the fiscal year ended October 31, 2005, should be multiplied by 100% to arrive at the amount eligible for qualified dividend income and 100% for the corporate dividends received deduction.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /S/ CHRISTOPHER O. BLUNT Christopher O.

EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: - - ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31, 2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. - - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,046.20 $ 6.29 $1,018.90 $ 6.21 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,042.55 $10.14 $1,015.15 $10.01 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,042.55 $10.14 $1,015.15 $10.01 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,047.35 $ 4.70 $1,020.45 $ 4.63 - --------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,046.70 $ 5.16 $1,020.00 $ 5.09 - --------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,044.55 $ 6.44 $1,018.75 $ 6.36 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Rosen of MacKay Shields LLC CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund normally invests at least 65% of its total assets in equity securities and is not managed primarily to produce current income. In implementing this strategy, the Fund normally invests in U.S. common stocks that we believe to be "undervalued," or selling below their value when purchased. The stocks in which the Fund invests typically pay dividends, but the Fund may invest in non-dividend-paying stocks if they meet the "undervalued" criterion. Normally, the Fund invests in stocks that are listed on a national securities exchange or are traded in the over-the-counter market. When assessing whether a stock is undervalued, we compare the stock's market price to the company's cash flow and interest coverage ratios, the company's book value, the estimated value of the company's assets, the company's growth rates, and its future earnings. We may sell stocks if we no longer believe they will contribute to meeting the investment objective of the Fund. During the 12-month reporting period, all of the assets and liabilities of MainStay Research Value Fund were transferred to MainStay Value Fund in exchange for shares of MainStay Value Fund. WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? During the 12-month reporting period, stocks generally advanced, despite political events and energy price fluctuations. Value stocks outperformed growth stocks at all capitalization levels. Crude-oil prices rallied to $69.81 per barrel and natural-gas prices broke $14 per million Btu before backing off somewhat. Major hurricanes affected supply-and-demand dynamics by damaging oil rigs and petrochemical plants. The price of gasoline rose to more than $3 a gallon, which threatened to slow consumer spending. Although hurricane-related stocks--including retailers, insurers, and companies on the Gulf Coast--were weakened, the long-term economic impact appeared to be manageable. The Federal Open Market Committee raised the targeted federal funds rate eight times during the 12-month reporting period, with a 25-basis-point increase on each occasion. (A basis point is one-hundredth of a percentage point.) On October 31, 2005, the federal funds target rate stood at 3.75%. During the reporting period, the yield curve flattened to reflect concern over a potential recession. Yet the most recent gross domestic product data suggests that the overall economy has remained resilient. WHICH FUND HOLDINGS WERE PARTICULARLY STRONG DURING THE REPORTING PERIOD? We saw strong results from energy-related holdings Transocean, Pride International, ENSCO International, and Rowen. Higher energy prices, hurricane-related supply pressures, and higher day rates benefited these stocks. We trimmed the Fund's positions in Transocean, ENSCO International, and Rowen as the stocks approached our price targets. HOW DID THE FUND'S FINANCIAL STOCKS PERFORM? We saw positive results from our stock selection in the financials sector. Operating improvements at Prudential Financial helped the company post strong earnings gains. The company shed noncore insurance operations and made cost-effective Asian acquisitions to help improve its return on equity. The Hartford Financial Services Group, St. Paul Travelers, and AFLAC were other insurance companies that showed strong results. The Goldman Sachs Group and State Street are two capital markets stocks that helped the Fund's performance. WERE THERE OTHER SUCCESS STORIES? Motorola benefited from good handset sales, in-creased market share, and excitement over a new product line-up. The company strengthened its balance sheet under the leadership of a new CEO. We pared back the Fund's position as the stock approached our price target. In the information technology sector, Texas Instruments showed strength from the Fund's initial purchase in January through the end of October. Wireless semiconductor sales and a share buyback program accelerated during the reporting period. Among consumer-related stocks, supermarket Kroger and food manufacturer Cadbury Schwepps were both strong. WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? Clothing retailer The Gap clearly hit a weak spot in its sales recovery when the fall season got off to a slower-than-expected start. Higher gasoline prices and slipping consumer confidence also hurt the stock. We are optimistic about better sales trends during the holiday season, and we believe that low valuations, a share repurchase program, and a strong balance sheet make the stock attractive. Shares of Molson Coors Brewing fell from our initial purchase in March until our sale later in the reporting period. When sales slowed and the company showed evidence of merger-integration difficulties, we sold the Fund's entire position in the stock. 8 MainStay Value Fund Pending generic-drug litigation and weaker-than-expected guidance for 2006 took a toll on Pfizer. Nevertheless, we like the stock for its upside potential, all-time low valuation, strong free cash flow, and 3% yield. We have hedged nearly all of the Fund's position using protective put contracts to limit downside exposure. Although we purchased the stock at what looked like a low price, printer manufacturer Lexmark continued to report operating problems and inventory issues. We concluded that the company's downside risk outweighed its upside potential, and we sold the Fund's entire position in late October 2005. Alcoa faced contracting margins because of higher energy prices and weakness in some end markets. Glass manufacturer Owens-Illinois was also hurt by higher costs. We sold the Fund's entire position in both of these stocks. Verizon Communications faced stronger competition in its wireline business, but continued to provide a high dividend yield. We used lower valuations to add to the Fund's position late in the reporting period. HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD? After selling many energy stocks that had reached our price targets, by October 31, 2005, the Fund was only slightly overweighted relative to the Russell 1000(R) Index in the energy sector. The Fund was overweighted in consumer staples and information technology, where we continue to find select value opportunities. At the end of the reporting period, the Fund was also overweighted in telecommunications services, where we judge asset value to be a near-term catalyst in a number of portfolio holdings. Our belief that some major drug companies have favorable risk/reward characteristics has supported our decision to overweight health care stocks. With gasoline prices finally having an impact on consumer spending, the Fund closed the reporting period underweighted in consumer discretionary stocks. We have, however, begun to find select opportunities in the sector. Since we have yet to find much value in utilities, the Fund remained underweighted relative to the Index in the sector. At the end of October 2005, the Fund was cautiously underweighted among interest-rate sensitive financials and REITS. The Fund was also underweighted relative to the Russell 1000(R) Index in industrials and materials.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Value Fund (the "Fund"), a diversified fund. The Fund currently offers six classes of shares. Class A shares, Class B shares, Class C shares, Class I shares, Class R1 shares and Class R2 shares. Class A shares, whose distribution commenced on January 3, 1995, are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class I, Class R1 and Class R2 shares are not subject to a sales charge. Distribution of Class B shares and Class C shares commenced on May 1, 1986 and September 1, 1998, respectively. Distribution of Class I shares, Class R1 shares and R2 shares commenced on January 2, 2004. The six classes of shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation, and other rights and conditions except that Class B shares and Class C shares are subject to higher distribution fee rates than Class A shares and Class R2 shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares and Class R1 shares are not subject to a distribution or service fee. Class R1 and Class R2 shares are authorized to pay to New York Life Investment Management LLC, its affiliates, or third-party service providers, as compensation for services rendered to shareholders of Class R1 or Class R2 shares, a shareholder service fee. The Fund's investment objective is to realize maximum long-term total return from a combination of capital growth and income. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (See Note 6.) (C) PURCHASED AND WRITTEN OPTIONS. The Fund may write covered call and put options on its portfolio securities or foreign currencies. Premiums are received and are recorded as liabilities. The liabilities are subsequently adjusted and unrealized appreciation or depreciation is recorded to reflect the current value of the options written. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are cancelled in closing purchase transactions are added to the proceeds or netted against the amount paid on the transaction to determine the realized gain or loss. By writing a covered call option, in exchange for the premium, the Fund foregoes the opportunity for capital appreciation above the exercise price should the market price of the underlying security or foreign currency increase but, as long as the obligation as a writer continues, have retained the risk of loss should the price of the underlying security decline. By writing a covered put option, the Fund, in exchange for the premium, accepts the risk of decline in the market value of the underlying security or foreign currency below the exercise price. After writing a put option, the Fund may 18 MainStay Value Fund incur a loss equal to the difference between the exercise price of the option and the sum of the market value of the underlying security plus the premium received from the sale of the option. A call option may be covered by the call writer's owning the underlying security throughout the option period. A call option may also be covered by the call writer's maintaining liquid assets valued at greater than the exercise price of the call written, in a segregated account with its custodian. The Fund may purchase call and put options on its portfolio securities. The Fund may purchase call options to protect against an increase in the price of the security it anticipates purchasing. The Fund may purchase put options on its securities to protect against a decline in the value of the security or to close out covered written put positions. The Fund may also purchase options to seek to enhance returns. Risks may arise from an imperfect correlation between the change in market value of the securities held by the Fund and the prices of options relating to the securities purchased or sold by the Fund and from the possible lack of a liquid secondary market for an option. The maximum exposure to loss for any purchased option is limited to the premium initially paid for the option. (D) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. (F) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (G) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (H) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (I) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and indirect wholly-owned subsidiary of New York Life, is responsible for the day-to-day portfolio management of the Fund. www.MAINSTAYfunds.com 19 NOTES TO FINANCIAL STATEMENTS (CONTINUED) The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.72% on assets up to $200 million, 0.65% on assets from $200 million to $500 million and 0.50% on assets in excess of $500 million. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.17% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. At October 31, 2005, the Fund had $235,721 of recoupment available. This amount is available until October 31, 2008. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005 and effective December 1, 2004, NYLIM agreed to voluntarily reimburse the expenses of the Fund so that the total operating expenses for Class A shares would not exceed on an annualized basis 1.22% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the year ended October 31, 2005, the Manager earned fees from the Fund in the amount of $4,582,549 and waived its fee and/or reimbursed expenses in the amount of $476,057. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of 0.36% of the Fund's average daily net assets on assets up to $200 million, 0.325% on assets from $200 million to $500 million and 0.25% on assets in excess of $500 million. To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. (B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES. The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund, with respect to Class A, Class B, Class C, and Class R2 shares, has adopted distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A and Class R2 Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A and Class R2 shares, which is an expense of the Class A and Class R2 shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Plans provide that the Class B and Class C shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. The Fund has adopted a shareholder services plan with respect to Class R1 and Class R2 shares. Under the terms of this plan, Class R1 and Class R2 shares are authorized to pay to NYLIM, its affiliates, or independent third-party providers, as compensation for services rendered, a shareholder services fee at the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2 shares. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $59,894 for the year ended October 31, 2005. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemptions of Class A, Class B and Class C shares of $6,542, $302,656 and $1,323, respectively, for the year ended October 31, 2005. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has entered into an agreement with Boston Financial Data Services ("BFDS") pursuant to which BFDS will perform certain of the services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2005, amounted to $2,369,108. (E) NON-INTERESTED TRUSTEES FEES. Non-Interested Trustees are paid an annual retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each Committee meeting and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, 20 MainStay Value Fund Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings. The Trust allocates trustees fees in proportion to the net assets of the respective Funds. Thus the Fund only pays a portion of the fees identified above. (F) CAPITAL. At October 31, 2005 New York Life and its affiliates held shares of Class I and Class R1 with net values of $1,139 and $1,138, respectively. This represents 100.0% of Class I and Class R1 shares' net assets and 0.0% of the Fund's total net assets at October 31, 2005. (G) OTHER. Pursuant to the Management Agreement, fees for the cost of legal services, included in Professional fees as shown on the Statement of Operations, provided to the Fund by the Office of the General Counsel of NYLIM amounted to $19,211 for the year ended October 31, 2005. The Fund pays the Manager a monthly fee for certain pricing and recordkeeping services provided under the Accounting Agreement at the annual rate of 1/20 of 1% for the first $20 million of average monthly net assets, 1/30 of 1% of the next $80 million of average monthly net assets and 1/100 of 1% of any amount in excess of $100 million of average monthly net assets. Fees for these services provided to the Fund by the Manager amounted to $100,518 for the year ended October 31, 2005. NOTE 4--CUSTODIAN: Investors Bank & Trust Company is the custodian of cash and securities of the Fund. Custodial fees are charged to the Fund based on the market value of securities in the Fund and the number of certain cash transactions incurred by the Fund. Formerly, State Street Bank and Trust Company acted as custodian for the Fund.

NOTE 11--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay Value Fund was $374,000. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 23 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Value Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the years in the two-year 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 the periods presented through October 31, 2003, were audited by other auditors, whose report dated December 18, 2003, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Value Fund of The MainStay Funds as of October 31, 2005, the results of its operations for the year then ended, and the changes in its net assets and financial highlights for each of the years in the two-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 24 MainStay Value Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager and Subadvisor have provided historically to the Fund, and also generally to other series of the Trust. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to-day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Trustees also considered information contained in management presentations to the Board's Performance Committee over the course of the past year. The Board's decision took account of, among other things, the Fund's underperformance when compared over several time periods with funds concluded by Trustees to be peers of the Fund, as well as steps the Subadvisor had taken to improve performance. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees reviewed information about the compensation structure for portfolio managers employed by the Manager and assessed whether that structure appears to align portfolio manager compensation with the long-term objectives of the Fund's shareholders. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the 28 MainStay Value Fund Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees noted that the Fund's contractual management fee had been reduced in accordance with the terms of the breakpoint schedule applicable to the Fund. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of the Fund and a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager or Subadvisor about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager and Subadvisor for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's historical and proposed contractual and net management fees, its gross and net expense ratio, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationships among the Manager, the Subadvisor and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the manager. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees and the Fund's anticipated net expense level. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 29 FEDERAL INCOME TAX INFORMATION--UNAUDITED The dividends paid by the Fund during the fiscal year ended October 31, 2005, should be multiplied by 100% to arrive at the amount eligible for qualified dividend income and 100% for the corporate dividends received deduction.

In the United States, mid- capitalization stocks outperformed small- and large-cap issues, and investors tended to prefer value stocks over growth stocks at all capitalization levels. The U.S. economy continued to advance throughout the reporting period, with positive growth in gross domestic product and gradually improving labor-market conditions. In August and September 2005, devastating hurricanes pummeled the Gulf region, destroying homes, flooding coastal cities, and taking hundreds of lives. At MainStay, we wish to express our heartfelt concern for the millions of people who were adversely affected by these natural disasters. At the end of August, crude-oil prices rose to record levels when rigs and refineries in the Gulf region faced hurricane-related setbacks. Higher oil and natural gas prices benefited stocks in the energy sector, but raised concerns about inflation. To keep the economy on track and inflation at bay, the Federal Open Market Committee raised the targeted federal funds rate eight times during the reporting period, with a 25-basis-point increase on each occasion. At the end of October 2005, the federal funds target rate stood at 3.75%, its highest level in more than four years. Since the economy and the markets are constantly changing, managing investments is a complex task. Fortunately, each MainStay Fund pursues its objective with the help of a well-defined investment approach that the portfolio managers seek to apply with discipline, care, and consistency. At MainStay, we take pride in offering a wide range of Funds suited to the needs of different types of investors. During the reporting period, MainStay introduced four new Asset Allocation Funds, each with a distinct risk/reward profile. The report that follows takes a closer look at the specific securities and decisions that affected your MainStay Fund investment during the 12 months ended October 31, 2005. We hope that you will review the report carefully to gain greater insight into your Fund's performance, holdings, and management style. Sincerely, /s/ Christopher O. Blunt Christopher O.

Effective 6/29/05, MainStay Blue Chip Growth Fund, which had assets of $234.1 million, merged into MainStay Large Cap Growth Fund, which had assets of $16.5 million. Performance for MainStay Large Cap Growth Fund includes the performance history of FMI Winslow Growth Fund from inception (7/1/95) through 3/31/05, during which time FMI Winslow Growth Fund's asset size generally was in the range of $4 million to $52 million. Performance history shown for MainStay Large Cap Growth Fund through 3/31/05, therefore, reflects performance of a much smaller portfolio than the current MainStay Large Cap Growth Fund. Performance shown may not be indicative of what performance would have been had the portfolio been larger. THE DISCLOSURE AND FOOTNOTES ON THE TWO PRECEDING PAGES ARE AN INTEGRAL PART OF THE TABLES AND GRAPHS AND SHOULD BE CAREFULLY READ IN CONJUNCTION WITH THEM. 6 MainStay Large Cap Growth Fund COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY LARGE CAP GROWTH FUND The example below is intended to describe the fees and expenses borne by shareholders during the six-month period from May 1, 2005, to October 31, 2005, and the impact of those costs on your investment. EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, if applicable, exchange fees, and sales charges (loads) on purchases, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the six-month period and held for the entire period from May 1 through October 31, 2005. This example illustrates your Fund's ongoing costs in two ways: ACTUAL EXPENSES The second and third data columns in the table below provide information about actual account values and actual expenses. You may use the information in these columns, together with the amount you invested to estimate the expenses that you paid during the six months ended October 31,2005. 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The fourth and fifth data columns in the table below provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or expenses you paid for the six-month period shown. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees, if applicable, exchange fees, or sales charges (loads). Therefore, the fourth and fifth data columns of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> ENDING ACCOUNT ENDING ACCOUNT VALUE (BASED VALUE (BASED BEGINNING ON ACTUAL EXPENSES ON HYPOTHETICAL EXPENSES ACCOUNT RETURNS AND PAID 5% RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/05 10/31/05 PERIOD(1) 10/31/05 PERIOD(1) CLASS A SHARES $1,000.00 $1,123.60 $ 7.49 $1,018.25 $ 7.12 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,119.55 $11.49 $1,014.25 $10.92 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,119.85 $11.49 $1,014.25 $10.92 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,128.80 $ 3.22 $1,022.00 $ 3.06 - --------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,124.70 $ 3.75 $1,021.50 $ 3.57 - --------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,122.75 $ 5.08 $1,020.25 $ 4.84 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Kelly, CFA, and R. Bart Wear, CFA, of Winslow Capital Management, Inc. CAN YOU DESCRIBE THE FUND'S INVESTMENT APPROACH? The Fund invests in companies that have the potential for above-average future earnings growth. Under normal circumstances, the Fund invests at least 80% of its total assets in large-capitalization companies. These companies have a market capitalization in excess of $4.0 billion at the time of purchase and generally have improving financial returns. In implementing this strategy, we look for companies that we believe have attractive attributes, such as consistent and sustainable future growth of revenue and earnings, low financial leverage with strong cash flow, high return on equity and a low debt-to-total-capital ratio, management focused on shareholder value, and market dominance. We use a "bottom-up" investment approach, basing investment decisions on company specific factors, not general economic conditions. We also employ strict sell disciplines. On April 1, 2005, FMI Winslow Growth Fund was reorganized as MainStay Large Cap Growth Fund Class A shares. Class B, C, I, R1, and R2 shares were subsequently added. Effective June 29, 2005, MainStay Blue Chip Growth Fund merged into MainStay Large Cap Growth Fund. The Fund is subadvised by Winslow Capital Management. WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31, 2005? The market rose during the last two months of 2004, as investors' summer worries about macro factors such as economic growth, corporate earnings, inflation, and interest rates lessened. During the first quarter of 2005, however, investor confidence waned amid growing concerns about climbing energy prices, rising inflation, higher interest rates, and slowing growth in corporate profits. This led to a pullback in stock prices and weak performance for the first three months of the year. In late spring 2005, investor sentiment improved when these worries began to seem excessive and stocks began to rise. This momentum carried over into the third calendar quarter, although stock prices took a step backward in October. WHICH SECTORS AND INDIVIDUAL STOCKS WERE AMONG THE FUND'S STRONG PERFORMERS FOR THE YEAR ENDED OCTOBER 31, 2005? We emphasize internal research and employ a bottom-up(1) stock-selection process to construct the Fund's portfolio. Since the Fund's sector weightings are primarily a residual of our individual stock deci- sions, sector results are less important to us than the performance of individual securities. The Fund's best individual performers during the reporting period came from the health care, information technology, and energy sectors. New drug offerings and a favorable outlook helped Genentech advance strongly during the reporting period. The Fund's long-held position in pharmacy benefit manager Caremark Rx also showed excellent performance. In information technology, Google saw its earnings soar and the stock advanced on the continuing shift to online advertising. Another important contributor to Fund performance was Corning, which benefited from a strong position in flat-panel glass displays used in TVs and computer monitors. In the energy sector, XTO Energy continued to benefit from favorable growth in natural gas reserves and production and a sharp rise in the price of natural gas during the reporting period. WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE? In a surprise announcement in late February 2005, Biogen Idec withdrew a new drug that had carried high expectations. The withdrawal caused the company's share price to decline sharply. Since the withdrawal had removed the company's major source of growth potential, we sold the Fund's position in the stock. Shares of Internet-auction giant eBay had an excellent run in calendar year 2004 and we reduced the Fund's position in mid-December 2004 on concerns about the stock's high valuation. When eBay announced a slightly below-consensus earnings outlook for 2005, the stock price weakened and we reduced the Fund's position to control risk. Typically, the subadvisor intends to invest substantially all of the Fund's investable assets in domestic securities. However, the Fund is permitted to invest up to 20% of its net assets in foreign securities. Foreign securities may be subject to greater risks than U.S. investments, including currency fluctuations, less-liquid trading markets, greater price volatility, political and economic instability, less publicly available information, and changes in tax or currency laws or monetary policy. 1. With bottom-up stock selection, securities are evaluated on their individual merits, which may include fundamental characteristics, quantitative measures, or both. The process differs from top-down stock selection, which uses broad economic, market, or industry considerations to narrow a portfolio's focus to specific areas or securities. www.MAINSTAYfunds.com 9 Our confidence in Mercury Interactive, a software and services provider to the business technology-optimization marketplace, waned over the course of the reporting period, and we eliminated the holding from the Fund. Zimmer Holdings, which designs and manufactures reconstructive orthopedic products, suffered from concerns about somewhat slower revenue growth. Although we have a positive long-term outlook for the company, we reduced the Fund's position to help control risk should the company's results fall short of our expectations. WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD? We increased the Fund's energy weighting over the course of the reporting period. This occurred, in part, by adding to the Fund's position in Schlumberger, an international leader in oil services. When Proctor & Gamble proposed the acquisition of Gillette, we saw potential in the merger and took advantage of a price dip to add to the Fund's position in Procter & Gamble. Since we believe that the managed-care industry has a favorable outlook, we purchased shares of WellPoint for the Fund. We also expect WellPoint to benefit from its recent merger with Anthem. In the telecommunication services sector, the Fund initiated a position in Mexico-based America Movil. The company is the fastest growing significant cell-phone operator in Latin America, where penetration levels remain relatively low. Another important purchase in health care was Alcon, a medical specialty company focused on eye care. The shares performed well from the time they were purchased through the end of the reporting period. WHICH STOCKS DID THE FUND SELL DURING THE REPORTING PERIOD? In addition to the sales we previously mentioned, we eliminated American International Group because of legal and accounting uncertainties that developed during the reporting period. We also sold Royal Caribbean Cruises because rising oil costs were having a negative effect on the company's earnings growth. We eliminated the Fund's positions in Teva Pharmaceutical Industries and Manpower because of questions regarding earnings growth, and we sold the Fund's position in Univision when television-advertising sales showed less strength than we had expected. WERE ANY ADJUSTMENTS MADE TO THE FUND'S SECTOR WEIGHTINGS? Although sector weightings are primarily a residual of our bottom-up stock-selection process, we did make a few notable weighting changes during the reporting period. In information technology, the Fund increased its underweighted position relative to the Russell 1000(R) Growth Index to an overweighted position by the end of June. We took profits in several issues, which reduced the Fund's information technology weighting by the end of October. The other notable change in the Fund's sector weightings occurred in the energy sector. The Fund increased its energy weighting to well above that of the Russell 1000(R) Growth Index in March. Although the size of the Fund's position was relatively modest during reporting period, strong stock selection helped the Fund's energy sector holdings outperform related stocks in the Index by a substantial margin. The Fund's health care sector weighting remained essentially unchanged during the reporting period and was similar to the health care sector weighting in the Index. Even so, the Fund benefited from excellent stock selection. We continued to underweight major pharmaceutical companies because of slowing earnings growth. We overweighted the managed care industry (UnitedHealth Group and Well- Point), pharmacy benefit management (Caremark Rx), and device companies (St. Jude Medical and Medtronic). These decisions produced a sector total return for the Fund that was more than twice that of health care stocks in the Index. 2.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company and comprises nineteen funds (collectively referred to as the "Funds"). These financial statements and notes relate only to MainStay Large Cap Growth Fund (the "Fund"), a diversified fund. The Fund commenced operations on April 1, 2005. On March 31, 2005 the fund acquired all the net assets of the FMI Winslow Growth Fund (the "Winslow Fund"), a series of the FMI Mutual Funds, Inc., pursuant to an Agreement and Plan of Reorganization approved by the shareholders of the Winslow Fund on March 28, 2005. The acquisition was accomplished by the transfer of all the assets and liabilities of the Winslow Fund (valued at $5,417,292), to the Fund. Following the transfer, 1,122,224 shares of the Fund were distributed to shareholders in liquidation of the Winslow Fund in a tax free exchange for 1,122,224 shares of the Winslow Fund. The reorganization qualifies as a tax-free reorganization for federal income tax purposes with no gain or loss recognized by the portfolios or their shareholders. The Fund constitutes the surviving entity for financial reporting purposes; therefore, it is deemed the "accounting survivor" for the merger. The financial statements of the Fund (fiscal year end of October 31) reflect the historical financial highlights of the Winslow Fund (fiscal year end of June 30) prior to the reorganization. On June 29, 2005, the Fund acquired substantially all the net assets of the MainStay Blue Chip Growth Fund, a series of the Trust, pursuant to an Agreement and Plan of Reorganization approved by the shareholders on June 27, 2005. The acquisition was accomplished by a transfer of all the assets and liabilities of the MainStay Blue Chip Growth Fund (valued at $234,008,138), to the Fund. Following the transfer, 45,899,942 shares of the Fund were distributed to shareholders in liquidation of the MainStay Blue Chip Growth Fund in a tax free exchange for 24,366,396 shares of the MainStay Blue Chip Growth Fund. The reorganization qualified as a tax-free reorganization for federal income tax purposes with no gain or loss recognized by the portfolios or their shareholders. The MainStay Blue Chip Growth Fund's net assets at the date of acquisition, including $15,306,040 and ($1,310,067) of unrealized appreciation (depreciation), respectively, ($168,915,585) of accumulated net realized loss and ($1,052,103) of undistributed net investment loss and ($846,002) of liabilities were combined with those of the MainStay Large Cap Growth Fund. The Fund constitutes the surviving entity for financial reporting purposes; therefore it is deemed the "accounting survivor" for the merger. Effective June 29, 2005, the Fund's operations are combined with that of the Mainstay Blue Chip Growth Fund in the accompanying Statement of Operations, Statements of Changes in Net Assets, and Financial Highlights. The Fund currently offers six classes of shares, Class A, Class B, Class C shares, Class I shares, Class R1 shares and Class R2 shares, whose distribution commenced on March 31, 2005. Class A shares are offered at net asset value per share plus an initial sales charge. No sales charge applies on investments of $1 million or more (and certain other qualified purchases) in Class A shares, but a contingent deferred sales charge is imposed on certain redemptions of such shares within one year of the date of purchase. Class B shares and Class C shares are offered without an initial sales charge, although a declining contingent deferred sales charge may be imposed on redemptions made within six years of purchase of Class B shares and within one year of purchase of Class C shares. Class I, Class R1 and Class R2 shares are not subject to sales charge. The six classes of shares bear the same voting (except for issues that relate solely to one class), dividend, liquidation and other rights and conditions except that Class B shares and Class C shares are subject to higher distribution fee rates than Class A shares and Class R2 shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares and Class R1 shares are not subject to a distribution or service fee. Class R1 and Class R2 shares are authorized to pay to New York Life Investment Management LLC, its affiliates, or independent third-party service providers, as compensation for services rendered to shareholders of Class R1 or Class R2 shares, a shareholder service fee. The Fund's investment objective is to seek long-term growth of capital. NOTE 2--SIGNIFICANT ACCOUNTING POLICIES: The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America and follows the significant accounting policies described below. (A) SECURITIES VALUATION. Equity securities are valued at the latest quoted sales prices as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Prices normally are taken from the principal market in which each security trades. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued by methods deemed in good faith by Board of Trustees to 18 MainStay Large Cap Growth Fund represent fair value. Reasons for which securities may be valued in this manner include, but are not limited to, trading for a security has been halted or suspended, a security has been de-listed from a national exchange, or trading on a security's principal market is temporarily closed at a time when under normal conditions it would be open. The Fund did not hold securities at October 31, 2005, that were valued in such manner. (B) SECURITIES LENDING. The Fund may lend its securities to broker-dealers and financial institutions. The loans are collateralized by cash or securities at least equal at all times to the market value of the securities loaned. The Fund may bear the risk of delay in recovery of, or loss of rights in, the securities loaned should the borrower of the securities experience financial difficulty. The Fund receives compensation for lending its securities in the form of fees or it retains a portion of interest on the investment of any cash received as collateral. The Fund also continues to receive interest and dividends on the securities loaned and any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. (see Note 7.) (C) FEDERAL INCOME TAXES. The Fund's policy is to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to the shareholders of the Fund within the allowable time limits. Therefore, no federal income or excise tax provision is required. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are withheld at the source. (D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on the ex-dividend date. The Fund intends to declare and pay dividends quarterly and capital gain distributions, if any, annually. Income dividends and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These "book/tax differences" are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between net investment loss, accumulated net realized loss on investments and additional paid-in-capital arising from permanent differences; net assets at October 31, 2005, are not affected. <Table> <Caption> NET ACCUMULATED NET ADDITIONAL INVESTMENT REALIZED LOSS PAID-IN LOSS ON INVESTMENTS CAPITAL $1,086,262 $(35,290) $(1,050,972) ------------------------------------------ </Table> The reclassification for the Fund is due to the reclassification of net operating losses that cannot be utilized for tax purposes. (E) SECURITY TRANSACTIONS AND INVESTMENT INCOME. The Fund records security transactions on the trade date. Realized gains and losses on security transactions are determined using the identified cost method. Dividend income is recognized on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the constant yield method over the life of the respective securities or, in the case of a callable security, over the period to the first date of call. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. Investment income and realized and unrealized gains and losses on investments of the Fund are allocated to separate classes of shares based upon their relative net assets on the date the income is earned or realized and unrealized gains and losses are incurred. (F) EXPENSES. Expenses of the Trust are allocated to the individual Funds in proportion to the net assets of the respective Funds when the expenses are incurred except where direct allocations of expenses can be made. Expenses (other than transfer agent expenses and expenses incurred under the distribution plans) are allocated to separate classes of shares based upon their relative net asset value on the date the expenses are incurred. The expenses borne by the Fund, including those of related parties to the Fund, are shown in the Statement of Operations. (G) USE OF ESTIMATES. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (H) INDEMNIFICATIONS. In the normal course of business the Fund enters into contracts with third party service providers that contain a variety of representations and warranties and which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. Based on experience, management is of the view that the www.MAINSTAYfunds.com 19 NOTES TO FINANCIAL STATEMENTS (CONTINUED) risk of loss in connection with these potential indemnification obligations is remote; however, there can be no assurance that material liabilities related to such obligations will not arise in the future that could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's manager. The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps the financial and accounting records required for the Fund. The Manager also pays the salaries and expenses of all personnel affiliated with the Fund and all the operational expenses that are not the responsibility of the Fund. Winslow Capital Management, Inc. (the "Subadvisor"), is responsible for the day-to-day portfolio management of the Fund. Prior to March 31, 2005, the Fund was advised by Fiduciary Management, Inc. ("FMI") and subadvised by the subadvisor. The Trust, on behalf of the Fund, pays the Manager a monthly fee for services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.80% on assets up to $250 million, 0.75% on assets from $250 million up to $500 million, 0.725% on assets from $500 million up to $750 million, 0.70% on assets from $750 million up to $2.0 billion, 0.65% on assets from $2.0 billion up to $3.0 billion, and 0.60% on assets in excess of $3.0 billion. The Manager has also voluntarily agreed to waive a portion of its management fee so that the management fee does not exceed 0.75% on assets up to $250 million. Effective August 1, 2005, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to reimburse the expenses of the Fund so that the total operating expenses (excluding taxes, interest, litigation, extraordinary expenses, and brokerage and other transaction expenses relating to the purchase or sale of portfolio investments) do not exceed, on an annualized basis, 1.40% of the average daily net assets of the Class A shares. An equivalent reimbursement, in an equal amount of basis points, will be applied to the other share classes. The Manager, within three years of incurring such expenses, may recoup the amount of any management fee waiver or expense reimbursement from the Fund pursuant to this agreement if such recoupment does not cause the Fund to exceed the expense limitations. This expense limitation may be modified or terminated only with the approval of the Board of Trustees. Prior to August 1, 2005, the Manager voluntarily agreed to waive other fees and/or reimburse the Fund so that total annual fund operating expenses would not exceed on an annualized basis 1.40% of the average daily net assets of the Class A shares, and such that there would be an equivalent reduction for the other classes of shares. For the period ended October 31, 2005, the manager earned from the Fund $838,898 and waived its fee and/or reimbursement expense in the amount of $397,089. For the period from March 31, 2005 through June 30, 2005, the Manager earned from the Fund $31,005 and waived its fee and/or reimbursed expenses in the amount of $82,942. Prior to March 31, 2005, the Winslow Fund paid FMI a monthly fee for services performed at an annual percentage of 1% of the Fund's average daily net assets. FMI was contractually obligated to reimburse the Winslow Fund for expenses over 2.00% of the daily net assets of the Winslow Fund. In addition to the reimbursement required under the management agreement, FMI voluntarily reimbursed the Winslow Fund for expenses over 1.30% of the daily net assets of the Fund. For the period from July 1, 2004 through March 31, 2005, FMI earned from the Fund $37,572 and waived its fee and/or reimbursement expense in the amount of $53,796. Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and the Subadvisor, dated April 1, 2005, the Manager paid the Subadvisor a monthly fee at an annual rate of the average daily net assets of all Winslow-serviced investment company assets managed by NYLIM, including the Fund as follows: 0.40% up to $250 million, 0.35% on assets from $250 million up to $500 million, 0.30% on assets from $500 million up to $750 million, 0.25% on assets from $750 million up to $1.0 billion, and 0.20% on assets in excess of $1.0 billion.

FMI voluntarily waived this minimum. For the year ended June 30, 2005, Administration fees of $7,514 are included in Management Fees in the accompanying Statement of Operations. (B) DISTRIBUTION AND SERVICE FEES The Trust, on behalf of the Fund, has a Distribution Agreement with NYLIFE Distributors LLC ("the Distributor"), an indirect wholly-owned subsidiary of New York Life. Effective March 31, 2005, the Fund, with respect to each class of shares other than Class I shares, has adopted distribution 20 MainStay Large Cap Growth Fund plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from the Fund at an annual rate of 0.25% of the average daily net assets of the Fund's Class A shares, which is an expense of the Class A shares of the Fund for distribution or service activities as designated by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a monthly fee, which is an expense of the Class B and Class C shares of the Fund, at the annual rate of 0.75% of the average daily net assets of the Fund's Class B and Class C shares. The Distribution Plans provide that the Class B, Class C and Class R2 shares of the Fund also incur a service fee at the annual rate of 0.25% of the average daily net asset value of the Class B or Class C shares of the Fund. Class I shares and Class R1 shares are not subject to a distribution or service fee. The Plans provide that the distribution and service fees are payable to the Distributor regardless of the amounts actually expended by the Distributor for distribution of the Fund's shares and service activities. The Fund has adopted a shareholder services plan with respect to Class R1 and R2 shares. Under the terms of this plan, Class R1 and Class R2 shares are authorized to pay to NYLIM, its affiliates, or independent third-party providers, as compensation for services rendered, a shareholder service fee at the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2 shares. Prior to March 31, 2005, the Winslow Fund had entered into a Distribution Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. The Plan provided that the Fund may incur certain costs which may not exceed the lesser of a monthly amount equal to 0.25% of the Fund's daily net assets or the actual distribution cost incurred during the year. (C) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $14,810 for the period ended October 31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT. Effective March 31, 2005, NYLIM Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing agent.

The Audit and Compliance Committee Chairman receives an additional $2,000 for each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each receive an additional $1,000 for each meeting of the Brokerage and Expense Committee, Operations Committee and Performance Committee attended, respectively. In addition, each Non-Interested Trustee is paid $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings.

NOTE 10--OTHER MATTERS: NYLIM and mutual funds that NYLIM advises have received requests for information from various government authorities and regulatory bodies regarding market timing, late trading, operations, fees, expenses, and other matters. NYLIM and the funds it advises have cooperated fully and completed responding to these requests. As previously reported in response to those requests for information and, as noted in the notes to the year-end 2004 financial statements of each fund of the Trust, NYLIM had been a party to arrangements with certain registered representatives of broker-dealers relating to the level of trading by clients of those registered representatives in shares of certain funds of the Trust. All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects that transactions under those arrangements and certain other levels of trading by fund shareholders over the period from 1999 to 2003 may have had on the funds. As a result of this review, in December 2005, NYLIM made payments totaling $5.9 million to nine MainStay funds. No payment was made with respect to the MainStay Large Cap Growth Fund. NYLIM has also agreed to reimburse or pay all expenses relating to the Board of Trustees' review of this matter and has paid substantially all of the costs associated with the other regulatory matters described in this note. In a separate matter, the SEC has raised concerns relating to a guarantee provided to shareholders of the MainStay Equity Index Fund and the fees and expenses of that fund as well as the related guarantee disclosure to fund shareholders. Discussions have been held with the SEC concerning a possible resolution of this matter. There can be no assurance of the outcome of these efforts. www.MAINSTAYfunds.com 23 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees and Shareholders of The MainStay Funds: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of the MainStay Large Cap Growth Fund (the "Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2005, and the related statements of operations and changes in net assets and the financial highlights for the four-month period ended October 31, 2005 and the year ended June 30, 2005. 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 statement of changes in net assets for the year ended June 30, 2004, and the financial highlights for the years presented through June 30, 2004, were audited by other auditors, whose report dated August 4, 2004, expressed an unqualified opinion thereon. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers. As to securities purchased or sold but not yet received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 MainStay Large Cap Growth Fund of The MainStay Funds as of October 31, 2005, and the results of its operations, the changes in its net assets and financial highlights for the four-month period ended October 31, 2005 and the year ended June 30, 2005, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 23, 2005 24 MainStay Large Cap Growth Fund TRUSTEES AND OFFICERS Following are the Trustees and Officers of The MainStay Funds, along with a brief description of their principal occupations during the past five years.

The Trustees also requested and received information from outside data providers and information and analysis from a third party consultant. The Trustees considered various industry and regulatory trends in their deliberations. In considering approval of these Agreements, and in evaluating the fairness of the compensation to be paid by the Fund, the Trustees met a number of times as a full Board and in executive sessions of only the Non-Interested Trustees to discuss the Board's consideration of the approval of the Agreements, and took into account a number of factors, as discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and the Subadvisor. The Trustees reviewed the services that the Manager has provided historically to the Fund, and also generally to other series of the Trust, and the services provided over a shorter term by the Subadvisor to the Fund. The Manager's services to the Trust have included investment management services, including the selection and supervision of portfolio managers or subadvisers, and administrative services, including interacting with other service providers to the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Fund filings, and other administrative services. The Subadvisor's services have included, among other things, providing the day-to- day management of the portfolio, providing reports to the Manager, and reviewing certain aspects of Fund filings. The Trustees considered, among other things, the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. In considering the Manager's and Subadvisor's practices relating to best execution of portfolio trades, the Board reviewed reports of the Fund's Brokerage Committee including with respect to analysis prepared by Plexus Group. The Trustees noted that the Fund's assets represented a significant portion of the Subadvisor's assets under management. The Trustees considered the Manager's supervision of the Fund's service providers and its attention to the compliance program of the Trust, the Manager, the Subadvisor and certain other service providers, as well as the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable conclusions of financial services research firm DALBAR Inc. of the services, investor complaint levels, and communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided to Trust shareholders. A majority of the Trustees, including a majority of the Non-Interested Trustees, concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and Subadvisor were such that, in the context of the Board's overall review of various factors, the Agreements should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of multiple groups of funds the Trustees concluded were comparable to the Fund. In conducting this review, the Trustees relied in part on information provided by outside data providers and were assisted in their analysis by a third party consultant. The Board's decision took account of, among other things, the Fund's favorable recent performance, and noted the Subadvisor's favorable performance as manager of FMI Winslow Growth Fund before it was reorganized with and into the Fund. The Trustees considered the cost to the Manager of the Agreements and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods; in assessing the cost the Trustees used the services of a third party consultant, which, among other things, reviewed allocations of various costs made by the Manager among the Fund and other clients of the Manager. The information reviewed by the Board included information about the general costs to the Manager and its affiliates of subsidizing expenses for some smaller series of the Trust pending the growth of their assets. The Trustees noted the Manager's agreement to limit the Fund's net expenses to a certain level with respect to the Fund, with the expectation that the Manager intended, over time, to implement measures designed to reduce the Trust's transfer agency fees. The Trustees considered certain benefits expected for, and risks borne by, the Manager and its affiliates, including benefits from soft dollar arrangements. The Trustees considered the services provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits to the Manager and its affiliates from those relationships. The information provided to the Trustees indicated that the profitability to the Manager and its affiliates arising directly from those other agreements was not excessive. The Trustees acknowledged certain benefits to the reputation of the Manager and its affiliates, as well to that of the Trust, from their association with each other. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund grows, or as the Trust grows overall, noting in particular the Manager's plans for marketing and distributing shares of various series of the Trust. They noted the Manager's willingness to implement contractual breakpoints, and that the contractual breakpoints in place for the management fee were intended to provide that the Fund's shareholders would share in benefits from economies of scale arising from the growth of Fund assets. The Trustees noted that the Fund's contractual management fee 28 MainStay Large Cap Growth Fund had been reduced in accordance with the terms of the breakpoint schedule applicable to the Fund. Acknowledging the difficulty of forecasting economies of scale, the Trustees generally expressed an intention to monitor the Manager's profitability and consider the application of fee breakpoints or other appropriate measures as the Board may determine from time to time. The Trustees reviewed historical information about changes in the Fund's expense and asset levels over time, as well as information about certain Fund expenses that would remain fixed even as Fund assets increase and, therefore, provide the Fund with benefits from economies of scale as the Fund grows. The Trustees noted that, to the extent the Fund's gross expenses currently are higher than its net expenses, economies of scale achieved through an increase in the Fund's assets might not directly benefit the Fund through lower net expenses. The Trustees considered various information about transfer agency expenses, including information showing that transfer agency fees of a significant number of series of the Trust (although not every such series or with respect to every share class of each series) tended to be high, when aggregated and expressed as a percentage of the assets of certain series, compared to the mutual fund industry average according to certain studies reviewed by the Board and, therefore, adversely affected gross expense ratios. The Board received information about potential effects on the Manager were it to subsidize certain portions of the Trust's transfer agency fees. The Trustees noted that a significant number of shareholders of the Trust's series had small amounts invested in the series, and have considered measures intended to increase average shareholder account size and/or otherwise reduce the Trust's transfer agency fees and expenses, including steps that the Manager has taken to encourage shareholders to consolidate or close small accounts. The Trustees considered services provided by other advisers to funds having investment objectives and policies similar to those of the Fund. The Board received, among other things, comparative data with respect to various types of fund expenses that third party data providers compiled using objective methodologies and provided for use by the Trustees. The Trustees received information regarding the combined advisory and administrative fees paid by other clients of the Manager, including other registered funds and separate institutional accounts, that had investment objectives similar to that of the Fund. The Trustees took into account information provided by the Manager about the relative scope of services provided to the Fund and to those accounts or explanations about the accounts' histories. In considering the extent of the fees received by the Manager for providing services to the Fund, the Trustees evaluated factors such as the fees and expenses borne by other registered funds in the market pursuing strategies generally similar to those followed by the Fund. The Trustees considered the Fund's current and proposed contractual and net management fees, its anticipated gross and net expense ratios, and various components of that expense ratio, in comparison to other funds in comparison groupings prepared by outside data providers using objective methodologies. The Trustees acknowledged the historical relationship between the Manager and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between them. The Trustees also took account of the results of their various discussions with the Manager concerning the levels of the Fund's contractual and net management fees, the Fund's anticipated net expense level, and the level of the subadvisory fee. The materials and other information described above were considered by the Trustees throughout the past year during in-person and telephonic meetings with personnel of the Manager, fund counsel, third party consultants, and independent counsel, and also were considered by the Non-Interested Trustees meeting separately and with independent counsel. The Trustees considered these factors in light of the recent reorganization of FMI Winslow Growth Fund, an unaffiliated fund, with and into the Fund and the separate reorganization of the Fund with the Blue Chip Growth Fund, another series of the Trust. The Trustees did not identify any particular information or any single factor that was controlling, or the particular weight any Trustee placed on any one factor for purposes of determining whether to vote in approval of the Agreements. The summary set out above describes the most important factors, but not all of the matters considered by the Trustees in coming to their decision regarding the Agreements. On the basis of their review, a majority of the Trustees and a majority of the Non-Interested Trustees concluded that each factor they considered, in the context of all of the other factors they considered, favored renewal of the Agreements, and it was the judgment of a majority of the Trustees and a majority of the Non-Interested Trustees that approval of these Agreements was in the best interests of the Fund and its shareholders. www.MAINSTAYfunds.com 29 PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that New York Life Investment Management LLC ("NYLIM") uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by calling 1-800-MAINSTAY (1-800-624-6782); (ii) by visiting the Fund's website at www.mainstayfunds.com; or (iii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

As of the end of the period covered by this report, the Registrant has adopted a code of ethics (the "Code") that applies to the Registrant's principal executive officer ("PEO") and principal financial officer ("PFO"). The Code was amended during the period covered by the report to designate new individuals as the PEO and PFO; a copy of the amended Code is filed herewith. The Registrant did not grant any waivers, including implicit waivers, from any provisions of the Code to the PEO or PFO during the period covered by this report. ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT. The Board of Trustees has determined that its Audit and Compliance Committee does not currently have any member that qualifies as an "audit committee financial expert" as defined under rules adopted by the Securities and Exchange Commission. In accordance the authority granted under the Registrant's Audit and Compliance Committee Charter, the Audit and Compliance Committee has retained a third party consultant to provide the Committee and the Registrant with the financial expertise, knowledge and skills similar to those of an audit committee financial expert. ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES. (a) Audit Fees The aggregate fees billed for the fiscal year ended October 31, 2005 for professional services rendered by KPMG LLP ("KPMG") for the audit of the Registrant's annual financial statements or services that are normally provided by KPMG in connection with statutory and regulatory filings or engagements for that fiscal year were $816,000. The aggregate fees billed for the fiscal year ended October 31, 2004 for professional services rendered by KPMG for the audit of the Registrant's annual financial statements or services that were normally provided by the KPMG in connection with statutory and regulatory filings or engagements for that fiscal year were $820,000. (b) Audit Related Fees The aggregate fees billed for assurance and related services by KPMG that are reasonably related to the performance of the audit of the Registrant's financial statements and are not reported under paragraph (a) of this Item were: (i) $15,000 for the fiscal year ended October 31, 2005, and (ii) $7,500 for the fiscal year ended October 31, 2004.

(e) Pre-Approval Policies and Procedures (1) The Registrant's Audit and Compliance Committee has adopted pre-approval policies and procedures (the "Procedures") to govern the Committee's pre-approval of (i) all audit services and permissible non-audit services to be provided to the Registrant by its independent accountant, and (ii) all permissible non-audit services to be provided by such independent accountant to the Registrant's investment adviser and to any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the Registrant (collectively, the "Service Affiliates") if the services directly relate to the Registrant's operations and financial reporting. In accordance with the Procedures, the Audit and Compliance Committee is responsible for the engagement of the independent accountant to certify the Registrant's financial statements for each fiscal year. With respect to the pre-approval of non-audit services provided to the Registrant and its Service Affiliates, the Procedures provide that the Audit and Compliance Committee may annually pre-approve a list of the types of services that may be provided to the Registrant or its Service Affiliates, or the Audit and Compliance Committee may pre-approve such services on a project-by-project basis as they arise. Unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit and Compliance Committee if it is to be provided by the independent accountant. The Procedures also permit the Audit and Compliance Committee to delegate authority to one or more of its members to pre-approve any proposed non-audit services that have not been previously pre-approved by the Audit and Compliance Committee, subject to the ratification by the full Audit and Compliance Committee no later than its next scheduled meeting. To date, the Audit and Compliance Committee has not delegated such authority. 3 (2) With respect to the services described in paragraphs (b) through (d) of this Item 4, no amount was approved by the Audit and Compliance Committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X. (f) There were no hours expended on KPMG's engagement to audit the Registrant's financial statements for the most recent fiscal year attributable to work performed by persons other than KPMG's full-time, permanent employees. (g) All non-audit fees billed by KPMG for services rendered to the Registrant for the fiscal years ended October 31, 2005 and October 31, 2004 are disclosed in 4(b)-(d) above. The aggregate non-audit fees billed by KPMG for services rendered to the Registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the Registrant were approximately: (i) $15,000, for the year ended October 31, 2005, and (ii) $0, for the fiscal year ended October 31, 2004. (h) The Registrant's Audit and Compliance Committee has determined that the non-audit services rendered by KPMG for the fiscal year ended October 31, 2005 to the Registrant's investment adviser and any entity controlling, controlled by, or under common control with the Registrant's investment adviser that provides ongoing services to the Registrant that were not required to be pre-approved by the Audit and Compliance Committee because they did not relate directly to the operations and financial reporting of the registrant were compatible with maintaining the respective independence of KPMG during the relevant time period.
