UNITED STATES SECURITIES AND EXCHANGE COMMISSION WASHINGTON, D.C. 20549 FORM N-CSR CERTIFIED SHAREHOLDER REPORT OF REGISTERED MANAGEMENT INVESTMENT COMPANIES Investment Company Act file number 811-04550 THE MAINSTAY FUNDS (Exact name of Registrant as specified in charter) 51 Madison Avenue, New York, NY 10010 (Address of principal executive offices) (Zip code) Marguerite E.H. Morrison, Esq. 169 Lackawanna Avenue Parsippany, NJ 07054 (Name and address of agent for service) Registrant's telephone number, including area code: (973) 394-4437 Date of fiscal year end: October 31 Date of reporting period: October 31, 2006 ITEM 1. REPORTS TO STOCKHOLDERS (MAINSTAY INVESTMENTS LOGO) MAINSTAY CAPITAL APPRECIATION FUND Message from the President and Annual Report October 31, 2006 MESSAGE FROM THE PRESIDENT Most stock and bond markets around the world provided positive total returns during the 12 months ended October 31, 2006. International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as 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. Prior to 9/1/98 (for Class C shares) and 12/31/03 (for Class I shares), performance for Class C and Class I shares includes the historical performance of Class B shares adjusted to reflect the applicable sales charge (or CDSC) and fees and expenses for Class C and 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $993.50 $ 6.53 $1,018.50 $ 6.61 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $989.55 $10.28 $1,014.75 $10.41 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $989.55 $10.28 $1,014.75 $10.41 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $997.20 $ 3.02 $1,022.00 $ 3.06 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1. Expenses are equal to the Fund's annualized expense ratio of each class (1.30% for Class A, 2.05% for Class B and Class C, and 0.60% for Class I) multiplied by the average account value over the period, divided by 365 and multiplied by 184 (to reflect the one-half year period). In the absence of waivers and/or reimbursements, expenses would have been higher. www.mainstayfunds.com 7 PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> Common Stocks 97.1 Short-Term Investments (collateral from securities lending 7 is 3.9%) Liabilities in Excess of Cash and Other Assets (4.1) </Table> See Portfolio of Investments on page 10 for specific holdings within these categories.

Spelman of MacKay Shields LLC HOW DID MAINSTAY CAPITAL APPRECIATION FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay Capital Appreciation Fund returned 8.21% for Class A shares, 7.40% for Class B shares, and 7.40% for Class C shares for the 12 months ended October 31, 2006. For the same period, the Fund's Class I shares returned 8.84%. All share classes underperformed the 10.84% return of Russell 1000(R) Growth Index,(1) the Fund's broad-based securities-market index, for the 12-month period. Class A and Class I shares outperformed--and Class B and Class C shares underperformed--the 7.42% return of the average Lipper(2) large-cap growth fund for the 12 months ended October 31, 2006.(3) WHAT DECISIONS HAD THE BIGGEST INFLUENCE ON THE FUND'S PERFORMANCE? Ineffective stock selection in the health care, financials, and information technology sectors had the most dramatic impact on the Fund's relative performance during the reporting period. An underweighted position in the consumer staples sector also had a negative impact on the Fund's overall performance. At the end of the reporting period, the Fund had no holdings in the telecommunication services and utilities sectors. This positioning also detracted from results. In contrast, individual stock selection in the industrials, energy, and materials sectors contributed positively to the Fund's relative performance. WHICH INDIVIDUAL SECURITIES WERE THE STRONGEST PERFORMERS DURING THE REPORTING PERIOD? Fisher Scientific, which makes analytical instruments, laboratory equipment, and reagents, was the Fund's top performer from a total-return perspective. Apple Computer was also a solid performer, primarily because of strong sales of iPod MP-3 players. Multiline retailer Kohl's enjoyed considerable sales growth, and the company sold its credit card portfolio--a move that reduced receivables and improved operating cash flow. Biopharmaceutical company Gilead Sciences and energy equipment & services company Weatherford International were among the Fund's other strong performers. WHICH STOCKS DETRACTED FROM PERFORMANCE? UnitedHealth Group saw its stock price decline primarily because of a cautious earnings outlook and heightened competition in the health care providers & services industry. Omnicare, a leading provider of pharmaceutical care for the elderly, saw its stock price decline because of litigation with UnitedHealth Group and a mislabeling mishap that led to a product recall. Shares of Internet services provider Yahoo! declined throughout the year and we sold the position in September. Oilfield equipment provider B.J. Services slid on concerns about a possible natural gas glut. EMC, the world leader in information management and storage, had a difficult third quarter and vowed to cut its workforce to make room for and integrate the company's 21 acquisitions in the last three years. WERE THERE ANY SIGNIFICANT PURCHASES AND SALES DURING THE REPORTING PERIOD? In the technology sector, we added a position in Akamai Technologies, a company that accelerates delivery of content and business processes online. The Fund also added a position in networking giant Cisco Systems. In the consumer discretionary sector, we added Comcast and News Corporation. We sold the Fund's entire positions in Yahoo! and eBay. We eliminated eBay because of slow earnings growth and the company's inability to expand its core business in the United States and abroad. In the consumer discretionary sector, we sold Chico's FAS, which had seen poor sales and earnings because of weaker-than-expected same-store sales in recent months. We also sold D.R. Horton and Lennar because of weakening fundamentals in the homebuilding subindustry. HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE DURING THE REPORTING PERIOD? During the reporting period, the Fund's weighting in the information technology sector significantly increased. We also increased the Fund's weightings in the health care and financials sectors. The Fund's weightings in the energy, industrials, and consumer discretionary sectors were reduced during the reporting period. The principal risk of growth stocks is that investors expect growth companies to increase their earnings at a certain rate that is generally higher than the rate expected for nongrowth companies. If these expectations are not met, the market price for the stock may decline significantly, even if earnings showed an absolute increase. 1.

Performance figures for the year ended October 31, 2006, reflect nonrecurring reimbursements from affiliates. Without these reimbursements, total returns would have been lower. See Note 1 on page 6.

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 commenced on January 3, 1995, Class B shares commenced on May 1, 1986, Class C shares commenced on September 1, 1998 and Class I 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I shares are not subject to sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The four classes of 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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, 2006, are not affected. ACCUMULATED NET REALIZED LOSS ADDITIONAL NET INVESTMENT LOSS ON INVESTMENTS PAID-IN-CAPITAL $11,223,939 $(3,205,000) $ (8,018,939) - ---------------------------------------------------------------------------- 18 MainStay Capital Appreciation Fund The reclassifications for the Fund are primarily due to the reimbursement payment (See Note 10 on page 22) and the fact that net operating losses cannot be carried forward for federal income tax purposes. (D) 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 using the effective interest rate method. 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 21.) (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 which could adversely impact the Fund.

(E) 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 pursuant to which it performs certain services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2006, amounted to $4,440,497. (F) NON-INTERESTED TRUSTEES FEES. For the year ended October 31, 2006, Non-Interested Trustees were paid an annual retainer of $45,000, $2,000 for each Board meeting attended, $1,000 for each Committee meeting attended and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses.

In addition, each Non-Interested Trustee received $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. 20 MainStay Capital Appreciation Fund (G) CAPITAL. At October 31, 2006, New York Life and its affiliates held shares of the Fund with the following values and percentages of net assets as follows: <Table> Class A $292,737 0.0*% - ---------------------------------------------------------------- Class C 82 0.0* - ---------------------------------------------------------------- Class I 1,155 100.0 - ---------------------------------------------------------------- </Table> * Less than one tenth of a percent.

NOTE 4--FEDERAL INCOME TAX: As of October 31, 2006, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> TOTAL ACCUMULATED CAPITAL UNREALIZED ACCUMULATED LOSSES APPRECIATION GAIN $ (183,500,350) $ 304,249,978 $ 120,749,628 - ---------------------------------------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to wash sales deferrals. At October 31, 2006, for federal income tax purposes, capital loss carryforwards of $183,500,350 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 $ 73,905 2011 49,074 2012 60,521 ------------------------------------------- $183,500 ------------------------------------------- </Table> The Fund utilized $54,785,926 of capital loss carryforwards during the year ended October 31, 2006. NOTE 5--FUND SECURITIES LOANED: As of October 31, 2006, the Fund had securities on loan with an aggregate market value of $41,310,602. The Fund received $42,535,123 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. Securities purchased with collateral received are valued at amortized cost. NOTE 6--CUSTODIAN: IBT 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 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. These funds paid a commitment fee, at an annual rate of .070%, up to September 6, 2006 at which time the rate changed to .060% 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 made or outstanding on the line of credit during the year ended October 31, 2006. NOTE 8--PURCHASES AND SALES OF SECURITIES (IN 000'S): During the year ended October 31, 2006, purchases and sales of securities, other than short-term securities, were $271,131 and $511,101, respectively. www.mainstayfunds.com 21 NOTES TO FINANCIAL STATEMENTS (CONTINUED) NOTE 9--CAPITAL SHARE TRANSACTIONS (IN 000'S): <Table> <Caption> YEAR ENDED OCTOBER 31, 2006 CLASS A CLASS B CLASS C CLASS I Shares sold 3,307 1,100 26 48 - ------------------------------------------------------------------------------- Shares redeemed (4,683) (6,728) (83) (48) - ------------------------------------------------------------------------------- Shares converted (See Note 1) 15,588 (17,032) -- -- - ------------------------------------------------------------------------------- Net increase (decrease) 14,212 (22,660) (57) -- - ------------------------------------------------------------------------------- </Table> <Table> <Caption> YEAR ENDED OCTOBER 31, 2005 CLASS A CLASS B CLASS C CLASS I Shares sold 1,235 1,826 32 --(a) - ------------------------------------------------------------------------------- Shares redeemed (3,789) (11,161) (121) --(a) - ------------------------------------------------------------------------------- Net decrease (2,554) (9,335) (89) --(a) - ------------------------------------------------------------------------------- </Table> (a) Less than one thousand shares. NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. The amount paid to the Fund was $3,205,000. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 22 MainStay Capital Appreciation 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 Capital Appreciation Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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 Capital Appreciation Fund of The MainStay Funds as of October 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. KPMG LLP SIGNATURE Philadelphia, Pennsylvania December 21, 2006 www.mainstayfunds.com 23 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, which include monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, such as working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's underperformance over longer time periods and its recent mid-range performance. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average 24 MainStay Capital Appreciation Fund shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoints that would reduce the Fund's management fee at levels above the breakpoints, and the fact that the breakpoints were intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund's management fee rate had been reduced by the breakpoint schedule applicable to the Fund, although they also noted that the Fund's asset size had decreased over the past several years. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. www.mainstayfunds.com 25 PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD A description of the policies and procedures that NYLIM uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by visiting the Fund's website at www.mainstayfunds.com; or (ii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as 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. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense. Prior to 9/1/98 performance of Class 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 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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.

Spelman of MacKay Shields LLC HOW DID MAINSTAY CONVERTIBLE FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay Convertible Fund returned 10.57% for Class A shares, 9.81% for Class B shares, and 9.73% for Class C shares for the 12 months ended October 31, 2006. All share classes underperformed the 13.13% return of the Merrill Lynch All Convertible Securities Index,(1) the Fund's broad-based securities-market index, for the 12-month period. All share classes also underperformed the 11.59% return of the average Lipper(2) convertible securities fund for the 12 months ended October 31, 2006. WHICH SECTORS WERE STRONG PERFORMERS AND WHICH ONES WERE WEAK DURING THE REPORTING PERIOD? The best-performing sectors for the Fund in absolute terms were oil services, financials, and lodging. Sectors that detracted from the Fund's absolute performance included media, health care, and semiconductors. WHICH INDIVIDUAL FUND HOLDINGS WERE THE STRONGEST PERFORMERS DURING THE REPORTING PERIOD? A position in the convertible bonds of oil services company Schlumberger was the Fund's strongest holding during the reporting period. Schlumberger benefited from increased spending for exploration and drilling, and the company's share price appeared inexpensive relative to future earnings prospects. Hilton's convertible bonds were also extremely strong during the reporting period. The company enjoyed increased room rates and high hotel occupancy. Fischer Scientific also advanced on strong organic sales growth, earnings growth, and free cash flow. The company is close to consummating a merger with Thermo-Electron, a leading manufacturer of laboratory equipment and instruments, and the deal may help Fischer Scientific broaden its product line. WHICH SECURITIES WERE WEAK PERFORMERS DURING THE REPORTING PERIOD? Sirius Satellite Radio's common stock and convertible bonds declined as investors became increasingly concerned about the company's continuing losses from operations. We believe the company has experienced early growth pains and remains a viable holding. Yahoo! shares and convertible bonds declined as the company reported several disappointing quarters, especially when compared with Google. Concerned about the prospects at Yahoo!, we sold the Fund's position in the company's convertible bonds in September 2006. Teva Pharmaceutical Finance shares and convertible bonds fell because of pricing pressures on generic manufacturers. We continue to invest in the company, because we believe it is well-run and we believe in the potential of the generic drug market. DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? We initiated a position in the convertible bonds of Wesco International, a distributor of electrical and industrial maintenance supplies. The company has benefited from strong demand for its products from utilities. We also purchased a significant position in the common shares of Microsoft. The shares were selling at very low historical and absolute valuations, even though the company is expected to release an upgraded operating system soon. The company has strong free cash flow and plenty of cash on its balance sheet, which we believe Microsoft may use to increase shareholder value. As we already mentioned, we sold the Fund's convertible bonds of Yahoo! in September. We also eliminated our position in the convertible bonds of Inco, a leading nickel-mining company, when several merger offers drove the share price above the level we thought represented full valuation. We also sold the Fund's Verizon convertible bonds and trimmed the Fund's position in NII International when the Issuers of convertible securities may not be as financially strong as issuers of 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. 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. 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 more than 100% and may generate taxable short-term capital gains. 1.

See footnote on page 6 for more information on Lipper Inc. www.mainstayfunds.com 9 companies' respective share prices approached our predetermined price targets. WERE THERE ANY CHANGES IN THE FUND'S WEIGHTINGS DURING THE REPORTING PERIOD? Yes, we increased the Fund's weightings in the consumer discretionary, health care, and industrials sectors. We reduced the Fund's weightings in the financials and telecommunication services sectors. The Fund's weightings in energy, information technology, and utilities were little changed during the 12-month reporting period. HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD? As of October 31, 2006, the Fund was significantly overweighted relative to the Merrill Lynch All Convertible Securities Index in energy and consumer staples. On the same date, the Fund held a significantly underweighted position in information technology. Other sectors were relatively in line with the benchmark--with consumer discretionary, health care, financials, telecommunication services, industrials, and materials slightly underweighted, and utilities slightly overweighted.

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 commenced on January 3, 1995, Class B shares commenced on May 1, 1986 and Class C shares commenced 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The three 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 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 also 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, as defined in Note 3, 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 trading of the New York Stock Exchange (generally 4:00 p.m. Eastern time). 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund held securities with a value of $1,457 that were valued in such manner. 22 MainStay Convertible Fund 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, as defined in Note 3, conclude that such events may have affected the accuracy of the last price reported on the local foreign market, the Manager or Subadvisor may, pursuant to procedures adopted by the Fund's Board of Trustees, adjust the value of the local price to reflect the impact on the price of such securities as a result of events. Additionally, international equity securities are also fair valued whenever the movement of a particular index exceeds certain amounts. In such cases, the securities are fair valued by applying factors provided by a third party vendor in accordance with the Fund's policies and procedures. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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 undistributed net investment income, accumulated net realized loss on investments and additional paid-in capital arising from permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED ACCUMULATED UNDISTRIBUTED NET REALIZED ADDITIONAL NET INVESTMENT LOSS ON PAID-IN INCOME INVESTMENTS CAPITAL $ 826,597 $ (865,022) $ 38,425 - -------------------------------------------- </Table> The reclassification for the Fund is primarily due to defaulted bond reclasses. (D) 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 using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. www.mainstayfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) (H) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 26.) (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and 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 the 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, to 0.62% on assets from $500 million to $1 billion and to 0.57% on assets in excess of $1 billion. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total ordinary operating expenses (total annual 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 written expense limitation 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.

All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust undertook a review of 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 $5.882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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 Convertible Fund NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 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 Convertible Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. KPMG SIGNATURE Philadelphia, Pennsylvania December 21, 2006 28 MainStay Convertible Fund BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's excellent investment performance during the past year and the Fund's mid-range performance over several other time periods relative to groupings of funds having similar investment mandates, and the Trustees noted that the Subadvisor had changed the portfolio manager of the Fund in 2004. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken www.mainstayfunds.com 29 certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoints that would reduce the Fund's management fee at asset levels above the breakpoints, and the fact that the breakpoints were intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund's management fee rate had been reduced by the breakpoint schedule applicable to the Fund. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to waive a certain portion of its management fee, and to maintain a limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. 30 MainStay Convertible Fund FEDERAL INCOME TAX INFORMATION (UNAUDITED) The dividends paid by the Fund during the fiscal year ended October 31, 2006, should be multiplied by 62.7% to arrive at the amount eligible for qualified dividend income, 90.7% to arrive at the amount eligible for qualified interest income and 69.0% for the corporate dividends received deduction.

SEC File Number: 811-04550 NYLIM-A09806 (RECYCLE LOGO) MS377-06 MSC11-12/06 05 (MAINSTAY INVESTMENTS LOGO) MAINSTAY EQUITY INDEX FUND Message from the President and Annual Report October 31, 2006 MESSAGE FROM THE PRESIDENT Most stock and bond markets around the world provided positive total returns during the 12 months ended October 31, 2006. International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as explained in this paragraph. The graph assumes an initial investment of $10,000 and reflects 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 3% and an annual 12b-1 fee of .25%. Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense. 1. Performance figures shown for the year ended October 31, 2006 reflect nonrecurring reimbursements from affiliates for professional fees and losses attributable to shareholder trading arrangements. (See Note 3(B) on page 25 of the Notes to Financial Statements for further explanation). If these nonrecurring reimbursements had not been made the total return (excluding sales charges) would have been 15.75%. 2.

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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,058.50 $3.32 $1,021.80 $3.26 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1. Expenses are equal to the Fund's annualized expense ratio of 0.64% multiplied by the average account value over the period, divided by 365 and multiplied by 184 (to reflect the one-half year period). In the absence of waivers and/or reimbursements, expenses would have been higher. 6 MainStay Equity Index Fund PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> Common Stocks 95.5 Short-Term Investments (collateral from securities lending 11.9 is 6.8%) Futures Contracts 0.2 Liabilities in Excess of Cash and Other Assets (7.6) </Table> See Portfolio of Investments on page 9 for specific holdings within these categories.

Ok of New York Life Investment Management LLC HOW DID MAINSTAY EQUITY INDEX FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, Class A shares of MainStay Equity Index Fund returned 15.85% for the 12 months ended October 31, 2006. The Fund, which offers only one share class, underperformed the 16.34% return of the S&P 500(R) Index,(1) the Fund's broad-based securities-market index, for the 12-month reporting period. Because the Fund faces real-world expenses that a hypothetical index does not, there will be times when the Fund lags the Index. The Fund outperformed the 15.74% return of the average Lipper(2) S&P 500 Index objective fund for the 12 months ended October 31, 2006.(3) DURING THE REPORTING PERIOD, WHICH INDUSTRIES WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S PERFORMANCE AND WHICH WERE THE WEAKEST? On the basis of impact, which takes weightings and total returns into account, the industry that made the strongest positive contribution to the Fund's performance was oil, gas & consumable fuels. Pharmaceuticals was the second-strongest contributor, and diversified financial services was third. The weakest contribution came from Internet software & services, followed by wireless telecommunication services, and diversified consumer services. DURING THE REPORTING PERIOD, WHICH INDUSTRIES HAD THE STRONGEST AND WHICH HAD THE WEAKEST TOTAL RETURNS? The best-performing S&P 500(R) industry in terms of total return was metals & mining, followed by diversified telecommunication services and real estate investment trusts. Diversified consumer services recorded the lowest total return of any industry in the Index. Internet & catalog retail had the second- lowest total return, followed by wireless telecommunication services. DURING THE REPORTING PERIOD, WHICH INDIVIDUAL STOCKS HAD THE STRONGEST AND WHICH HAD THE WEAKEST TOTAL RETURNS? The S&P 500(R) Index stock with the highest total return for the 12-month reporting period was Allegheny Technologies. NVIDIA was second, followed by NuCor. The Index stock with the lowest total return for the reporting period was Calpine, followed by Dana and Apollo Group. WHICH STOCKS WERE THE GREATEST POSITIVE CONTRIBUTORS TO THE FUND'S PERFORMANCE AND WHICH WERE THE GREATEST DETRACTORS? On the basis of impact, which takes weightings and total returns into consideration, the stocks that made the greatest positive contributions to the Fund's performance were ExxonMobil, Bank of America, and AT&T. The weakest contributor in terms of impact was Dell, followed by Yahoo! and UnitedHealth Group. WERE THERE ANY CHANGES IN THE MAKEUP OF THE S&P(R) 500 INDEX DURING THE REPORTING 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. In addition, Standard & Poor's may occasionally adjust the Index to better reflect the companies that Standard & Poor's believes are most representative of the makeup of the U.S. economy. During the 12-month reporting period, there were 27 additions to the S&P 500(R) Index and 27 deletions from it. Notable additions included Amazon.com, GenWorth Financial, Google, Legg Mason, and Chicago Mercantile Exchange. Notable deletions included Calpine, Dana, Cooper Tire & Rubber, and Gateway. The Fund was closed to new investors and 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 5 for more information on the S&P 500(R) Index. 2. See footnote on page 5 for more information on Lipper Inc. 3. Performance figures for the year ended October 31, 2006, reflect nonrecurring reimbursements from affiliates. Without these reimbursements, total returns would have been lower. See Note 1 on page 5.

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 Equity Index Fund (the "Fund"). The Board of Trustees of the Trust approved the closure of the Fund to new investors and new share purchases effective January 1, 2002. Existing shareholders are permitted to reinvest dividends only and NYLIFE LLC will continue to honor the unconditional guarantee associated with the Fund. (See Note 10 on page 27.) 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 S&P 500(R) 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 each day the fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006 the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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 Fund declared a dividend of $0.7405 per share which was paid on December 19, 2006, and also underwent a reverse share split on that day. The reverse share split rate was 0.98483 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 on page 27.) 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 2006. The following table discloses the current year reclassifications between accumulated distributions in excess of net investment income, accumulated net realized loss on investments and additional paid-in-capital arising from permanent differences; net assets at October 31, 2006, are not affected. <Table> <Caption> UNDISTRIBUTED ACCUMULATED NET INVESTMENT NET REALIZED LOSS ADDITIONAL INCOME ON INVESTMENTS PAID-IN-CAPITAL $(86,185) $(429,812) $515,997 - --------------------------------------------------------- </Table> The reclassifications for the Funds are primarily due to real estate trust distributions and the reimbursement payment (See Note 11 on page 27). www.mainstayfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) (D) 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 using the effective interest rate method. Discounts and premiums on short-term securities are accreted and amortized, respectively, on the straight line method. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) 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. (I) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 26.) (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New 24 MainStay Equity Index Fund York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 the services performed and the facilities furnished at an annual percentage of the Fund's average daily net assets as follows: 0.25% on assets up to $1.0 billion, 0.225% on assets from $1.0 billion to $3.0 billion and 0.20% on assets in excess of $3.0 billion. NYLIM has also voluntarily agreed to waive its management fee by 0.06% to 0.19% on assets up to $1.0 billion, to 0.165% on assets from $1.0 billion to $3.0 billion and to 0.14% on assets in excess of $3.0 billion. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total ordinary operating expenses (total annual 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, 0.60% of the average daily net assets of the Fund. 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 written expense limitation 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, 2006, this limit was 0.65% of the average daily net assets of the Fund. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $1,312,254 and waived its fees in the amount of $735,844. As of October 31, 2006, the amounts of waived fees that are subject to possible recoupment by the Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $209,184 $420,903 $630,087 - -------------------------------- </Table> * The expense limitation agreement became effective in 2005 and the recoupments will start to expire in 2008. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (B) PAYMENT FROM AFFILIATES. NYLIM reimbursed or paid all expenses relating to the Board of Trustees' review of certain shareholder trading matters as described below in the footnote relating to "Other Matters." (See Note 11 on page 27.) The total costs associated with the Board of Trustees' review were approximately $849,975 and included payments to certain third party service providers. The amount that was reimbursed to the Fund was $60,567. Additional payments were made by affiliates relating to the shareholder trading matters. Further discussion regarding these payments by affiliates can be found below in the footnote relating to "Other Matters." (C) DISTRIBUTION FEES 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 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. (D) SALES CHARGES. The Fund was also advised that the Distributor retained contingent deferred sales charges on redemption of Class A shares of $15 for the year ended October 31, 2006. (E) 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 pursuant to which it performs certain services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2006, amounted to $855,624. (F) NON-INTERESTED TRUSTEES FEES. For the year ended October 31, 2006, Non-Interested Trustees were paid an annual retainer of $45,000, $2,000 for each Board meeting attended, $1,000 for each Committee meeting attended and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee received an additional annual retainer of $20,000. The Audit and Compliance Committee Chairman received an additional $2,000 for www.mainstayfunds.com 25 NOTES TO FINANCIAL STATEMENTS (CONTINUED) each meeting of the Audit and Compliance Committee attended and the Chairpersons of the Brokerage and Expense Committee, Operations Committee and Performance Committee each received an additional $1,000 for each meeting of the respective committee meetings attended. In addition, each Non-Interested Trustee received $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. (G) OTHER. Pursuant to an Amended and Restated Management Agreement between the Fund and NYLIM, the cost of legal services provided to the Fund by the Office of the General Counsel of NYLIM are payable directly by the Fund. For the year ended October 31, 2006, these fees, which are included in Professional fees shown on the Statement of Operations, were $15,037. 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 $186,018 for the year ended October 31, 2006. NOTE 4--FEDERAL INCOME TAX: As of November 30, 2005, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> ACCUMULATED OTHER TOTAL ORDINARY CAPITAL TEMPORARY UNREALIZED ACCUMULATED INCOME LOSSES DIFFERENCES APPRECIATION GAIN $6,649,961 $ (112,880,274) $64,621 $167,814,081 $61,648,389 - ---------------------------------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to wash sale deferrals. The other temporary differences are primarily due to mark-to-market of futures contracts. At November 30, 2005, for federal income tax purposes, capital loss carryforwards of $112,880,274 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) 2010 $ 80,388 2011 29,198 2012 3,294 ------------------------------------------- $112,880 ------------------------------------------- </Table> The Fund utilized $9,465,664 of capital loss carryforwards during the tax year ended November 30, 2005. The tax character of distributions paid during the years ended October 31, 2006 and October 31, 2005 shown in the Statement of Changes in Net Assets, were as follows: <Table> <Caption> 2006 2005 Distributions paid from: Ordinary Income $6,709,434 $6,540,173 - ----------------------------------------------------------- </Table> NOTE 5--FUND SECURITIES LOANED: As of October 31, 2006, the Fund had securities on loan with an aggregate market value of $32,432,748. The Fund received $33,543,359 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. Securities purchased with collateral received are valued at amortized cost. NOTE 6--CUSTODIAN: IBT 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 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. These funds paid a commitment fee, at an annual rate of .070%, up to September 6, 2006 at which time the rate changed to .060% 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 made or outstanding on the line of credit during the year ended October 31, 2006. NOTE 8--PURCHASES AND SALES OF SECURITIES (IN 000'S): During the year ended October 31, 2006, purchases and sales of securities, other than short-term securities, were $23,683 and $152,676, respectively. 26 MainStay Equity Index Fund NOTE 9--CAPITAL SHARE TRANSACTIONS (IN 000'S): <Table> <Caption> YEAR ENDED YEAR ENDED OCTOBER 31, OCTOBER 31, 2006 2005 Shares sold (a) 5 172 - ------------------------------------------------------------------- Shares issued in reinvestment of distributions (a) 150 --(b) - ------------------------------------------------------------------- 155 172 Shares redeemed (a) (2,974) (2,544) - ------------------------------------------------------------------- Net decrease (a) (2,819) (2,372) - ------------------------------------------------------------------- </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 19, 2006. (See Note 2(C) on page 23.) (b) Less than one thousand 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. (See Note 3 on page 24.) 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. NOTE 11--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. The amount paid to the Fund was $516,000. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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 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. NOTE 12--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 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 Equity Index Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. KPMG LLP SIGNATURE Philadelphia, Pennsylvania December 21, 2006 28 MainStay Equity Index Fund BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager (the "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of the Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager, and data and analysis from an outside data provider and a third party consultant. In their deliberations, the Trustees considered various regulatory developments and industry trends, including the reduction of fees or net expense ratios by certain other equity index funds. In considering the approval of the Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under the Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services and administrative services. The investment management services include, but are not limited to, monitoring and evaluating the Fund's investment program and investment results, providing the day-to-day portfolio management of the Fund, determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets, and the Fund's compliance with its investment policies and restrictions. The administrative services include, but are not limited to, working with other service providers of the Trust, maintaining certain Fund records, providing office space, managing reverse stock splits, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Trustees also considered the Manager's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Manager's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust and certain other service providers. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager, has provided to Trust shareholders. The Trustees acknowledged the guarantee feature associated with the Fund's shares 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 Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and, in consultation with an outside data provider and a third party consultant, compared that performance to that of other having similar investment objectives. The Board's decision took account of, among other things, the Fund's investment results that, consistent with its investment objective, corresponded to the total return performance of publicly traded common stocks represented by the S&P 500 Index, and the sensitivity of index funds' relative net performance to their net expense ratios. 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 reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreement, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher invest- www.mainstayfunds.com 29 ment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. The Trustees noted that the Fund had not reached the asset level at which breakpoints would reduce the Fund's management fee rate, and that the Fund can reach that asset level only through capital appreciation so long as the Fund remains closed to new share purchases. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other registered fund clients of the Manager having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds having similar investment objectives. The Trustees noted that recent information suggested the net expense ratios of these other funds have been reduced noticeably over the prior year. The Trustees generally acknowledged the historical relationship between the Manager and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Trust and the Manager. The Trustees noted the Manager's agreement to waive a certain portion of its management fee, and to lower the limit on the Fund's net expenses. 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering 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 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 the Agreement was in the best interests of the Fund and its shareholders. 30 MainStay Equity Index Fund FEDERAL INCOME TAX INFORMATION (UNAUDITED) The dividends paid by the Fund during the fiscal year ended October 31, 2006, should be multiplied by 100% to arrive at the amount eligible for qualified dividend income, 1.6% to arrive at the amount eligible for qualified interest income and 100% for the corporate dividends received deduction.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as 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 4.5% 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. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense. Prior to 9/1/98, performance of Class C and I shares includes the historical performance of Class B shares adjusted to reflect the applicable sales charge (or CDSC) and fees and expenses for Class C and 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,039.45 $5.40 $1,019.75 $5.35 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,035.70 $9.24 $1,016.00 $9.15 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,035.70 $9.24 $1,016.00 $9.15 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,042.05 $2.93 $1,022.15 $2.91 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1. Expenses are equal to the Fund's annualized expense ratio of each class (1.05% for Class A, 1.80% for Class B and Class C, and 0.57% for Class I) multiplied by the average account value over the period, divided by 365 and multiplied by 184 (to reflect the one-half year period). In the absence of waivers and/or reimbursements, expenses would have been higher. www.mainstayfunds.com 7 PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> U.S. Government & Federal Agencies 90.1 Short-Term Investments (collateral from securities lending 10.6 is 8.0%) Asset-Backed Securities 4.1 Mortgage-Backed Securities 3.5 Corporate Bonds 1.6 Municipal Bond 0.5 Liabilities in Excess of Cash and Other Assets (10.4) </Table> See Portfolio of Investments on page 10 for specific holdings within these categories.

Excluding all sales charges, MainStay Government Fund returned 4.26% for Class A shares, 3.60% for Class B shares, and 3.48% for Class C shares for the 12 months ended October 31, 2006. Over the same period, Class I shares returned 4.78%. Class I shares outperformed--and Class A, Class B, and Class C shares underperformed--the 4.58% return of the Lehman Brothers(R) Government Bond Index,(1) the Fund's broad-based securities-market index, for the 12-month period. Class A and Class I shares outperformed--and Class B and Class C shares underperformed--the 3.76% return of the average Lipper(2) general U.S. government fund for the 12 months ended October 31, 2006. HOW WAS THE FUND POSITIONED RELATIVE TO ITS PEERS? MainStay Government Fund was positioned for rising interest rates, tighter spreads,(3) lower interest-rate volatility, and a steeper Treasury yield curve. With the exception of the yield curve steepening, each of these events occurred and positively affected the Fund's performance. To execute our strategy, we actively adjusted the Fund's duration, sector weightings, and issue selection. We assumed prudent sector and security risks to boost the Fund's yield relative to its duration, and the improvement was an important contributor to the Fund's total return. Our analysis suggests that the Fund was not as exposed to longer-maturity Treasurys as were many other funds in its Lipper universe. By itself, this posture would have detracted from the Fund's relative performance for the reporting period when the yield curve flattened between its two- and 30-year points. Other aspects of the Fund's positioning, however, were more than able to compensate. The Fund's duration posture, for example, made the Fund less sensitive than the median peer fund to higher rates. That would partially explain why Class I shares outperformed relative to the Fund's peers. HOW DID YOU SEEK TO ENHANCE THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? We maintained overweighted positions in agency debentures and mortgage-backed securities, and we underweighted Treasury securities to generate incremental yield. We substituted higher-yielding subordinated agency debt and callable agency debentures for senior, noncallable agency debt. The callable agency debentures benefited from lower interest-rate volatility and performed especially well. We overweighted issues that were less prone to extension risk, or the risk that durations would lengthen as interest rates rose. Mortgage-backed securities collateralized by 15-year loan terms and balloon loans fit this profile. We underweighted securities guaranteed by Ginnie Mae, because their rich valuations were difficult to justify relative to similar securities guaranteed by Fannie Mae and Freddie Mac. Investors appeared to share our valuation concerns and backed away from Ginnie Maes during the reporting period. Demand from overseas accounts also declined as the U.S. dollar weakened. WHAT OTHER STRATEGIES DID YOU EMPLOY DURING THE REPORTING PERIOD? We purchased interest-only mortgage pass-through strips for the Fund to capitalize on a slowdown in housing price appreciation. Homeowners are less inclined to cash out on the equity in their homes as housing prices moderate. In turn, mortgage loans are slower to prepay, and that dynamic can positively impact the price performance of interest-only pass-through strips. To fund the trade, we sold the Fund's positions in higher-coupon (7% and 7.5%) mortgage- backed securities, whose prepayment levels were still surprisingly responsive to rate changes, despite the age of the securities' collateral. Finally, spreads of asset-backed securities, commercial mortgage-backed securities, and investment-grade corporate bonds were well-contained during the reporting period. As a result, the Fund's modestly overweighted positions in these sectors outperformed Treasury securities with similar durations. 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 more than 100% and may generate taxable short- term capital gains. Funds that invest in bonds are subject to interest-rate risk and can lose principal value when interest rates rise. 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 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 commenced on January 3, 1995. Distribution of Class B shares and Class C shares commenced on May 1, 1986 and September 1, 1998, respectively. Distribution of Class I 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I shares are not subject to sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The four classes of 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, as defined in Note 3, 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 trading of the New York Stock Exchange (generally 4:00 p.m. Eastern time). Temporary cash investments acquired over 60 days prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006 the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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 undistributed net investment income and accumulated net realized loss on investments arising from 20 MainStay Government Fund permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED ACCUMULATED UNDISTRIBUTED NET NET REALIZED LOSS INVESTMENT INCOME ON INVESTMENTS $356,615 $(356,615) ------------------------------------- </Table> The reclassifications for the Fund are primarily due to paydowns. (D) 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 using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) 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, the Fund forgoes principal and interest on the securities. The 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 liquid assets 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. (I) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 page 24.) (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 www.mainstayfunds.com 21 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and 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 the 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. NYLIM has voluntarily agreed to waive its management fee by 0.10% to 0.50% on assets up to $1 billion and to 0.45% on assets in excess of $1 billion. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total ordinary operating expenses (total annual 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, 1.05% 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $1,981,647, and waived its fees in the amount of $973,891. As of October 31, 2006, the amounts of waived fees that are subject to possible recoupment by the Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $302,892 $643,616 $946,508 ---------------------------- </Table> <Table> * The expense limitation agreement became effective in 2005 and the recompments will start to expire in 2008. </Table> Pursuant to the terms of a Subadvisory Agreement between NYLIM and the Subadvisor, 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. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (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 and 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 22 MainStay Government Fund 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 $21,882 for the year ended October 31, 2006. 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 $2,605, $144,947 and $1,154, respectively, for the year ended October 31, 2006. (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 pursuant to which it performs certain services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2006 amounted to $1,185,714. (E) NON-INTERESTED TRUSTEES FEES. For the year ended October 31, 2006, Non-Interested Trustees were paid an annual retainer of $45,000, $2,000 for each Board meeting attended, $1,000 for each Committee meeting attended and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee received an additional annual retainer of $20,000. The Audit and Compliance Committee Chairman received 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 received an additional $1,000 for each meeting of the respective committee meetings attended. In addition, each Non-Interested Trustee received $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, 2006, New York Life and its affiliates held shares of the Fund with the following values and percentages of net assets as follows: <Table> Class A $ 172 0.0*% - -------------------------------------- Class C 107 0.0* - -------------------------------------- Class I 1,057 99.6 - -------------------------------------- </Table> * Less than one tenth of one percent (G) OTHER. Pursuant to an Amended and Restated Management Agreement between the Fund and NYLIM, the cost of legal services provided to the Fund by the Office of the General Counsel of NYLIM are payable directly by the Fund. For the year ended October 31, 2006, these fees, which are included in Professional fees shown on the Statement of Operations, were $9,725. 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.

NOTE 4--FEDERAL INCOME TAX: As of October 31, 2006, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> ACCUMULATED OTHER TOTAL ORDINARY CAPITAL TEMPORARY UNREALIZED ACCUMULATED INCOME LOSSES LOSSES DEPRECIATION LOSS $410,715 $(42,390,916) $(145,457) $(1,163,777) $(43,289,435) ----------------------------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to premium amortization adjustments. The other temporary differences are primarily due to distribution payable. At October 31, 2006, for federal income tax purposes, capital loss carryforwards of $42,390,916 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 2014 2,598 ------------------------------------------- $42,391 ------------------------------------------- </Table> The tax character of distributions paid during the years ended October 31, 2006 and October 31, 2005, shown in the Statement of Changes in Net Assets, was as follows: <Table> <Caption> 2006 2005 Distributions paid from: Ordinary Income $12,422,264 $10,388,274 - ----------------------------------------------------------- </Table> www.mainstayfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) NOTE 5--FUND SECURITIES LOANED: As of October 31, 2006 the Fund had securities on loan with an aggregate market value of $24,274,887.

Securities purchased with collateral received are valued at amortized cost. NOTE 6--CUSTODIAN: IBT is the custodian of cash and securities of the Fund.

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. These funds paid a commitment fee, at an annual rate of .070%, up to September 6, 2006 at which time the rate changed to .060% 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.

All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust undertook a review of 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 $5.882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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 24 MainStay Government 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 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 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 Government Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. KPMG LLP SIGNATURE Philadelphia, Pennsylvania December 21, 2006 26 MainStay Government Fund BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's underperformance when compared over several time periods with groupings of funds having similar investment mandates and the Manager's continued monitoring of the Fund's performance. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher invest- www.mainstayfunds.com 27 ment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at asset levels above the breakpoint and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund had not reached the asset level at which the breakpoint would reduce the Fund's management fee rate. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other registered fund clients of the Manager and Subadvisor having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to waive a certain portion of its management fee, and to maintain a limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement 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 13% of the ordinary income dividends paid during its fiscal year ended October 31, 2006 as attributable to interest income from Direct Obligations of the United States.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,047.90 $5.47 $1,019.70 $5.40 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,043.25 $9.32 $1,015.95 $9.20 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,043.25 $9.32 $1,015.95 $9.20 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,048.90 $4.13 $1,021.00 $4.08 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Matthew Philo, CFA, of MacKay Shields LLC HOW DID MAINSTAY HIGH YIELD CORPORATE BOND FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay High Yield Corporate Bond Fund returned 9.58% for Class A shares, 8.92% for Class B shares, and 8.91% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund's Class I shares returned 10.02%. All share classes underperformed the 10.29% return of the Credit Suisse High Yield Index,(1) the Fund's broad-based securities-market index, for the 12-month period. Class A and Class I shares outperformed--while Class B and Class C shares underperformed--the 9.18% return of the average Lipper(2) high current yield fund for the 12 months ended October 31, 2006.(3) WHY DID THE FUND UNDERPERFORM THE CREDIT SUISSE HIGH YIELD INDEX DURING THE REPORTING PERIOD? The Fund's underperformance resulted primarily from our conservative positioning. During the reporting period, spreads--or the differences in yield between high-yield corporate bonds and U.S. Treasurys--remained relatively tight. In light of historical default expectations, we felt that compensation for assuming additional risk was inadequate, so we reduced the Fund's exposure to lower-quality high-yield assets and increased exposure to higher-quality high-yield bonds. While highly speculative securities were rewarded during the reporting period, we felt that any shock to the market might cause riskier assets to underperform. WHAT WAS THE FUND'S DURATION POSITIONING DURING THE REPORTING PERIOD? Duration is primarily a residual of our investment process, but we sought to reduce duration risk by maintaining the Fund's portfolio within a reasonable range of the benchmark. Historically, the duration of the high-yield market has varied around four years. In light of tight spreads and low default rates, however, the Fund had a shorter duration. HOW WAS THE FUND POSITIONED FROM AN INDUSTRY PERSPECTIVE? We are bottom-up investors, and the Fund's industry exposure is primarily the result of individual security selection. During the reporting period, the Fund remained underweighted in automotive bonds. GM and Ford became high-yield issuers in 2005, and because both issuers have considerable outstanding debt, their bonds have a major influence on the high-yield market. The Fund maintained its position in General Motors Acceptance Corp., which benefited from reports about GM's plans to sell its finance arm. Although most of the Fund was conservatively positioned, the Fund's airline holdings were rather volatile, responding directly to changes in oil prices. The Fund maintained its investments in Delta Airlines and Northwest Airlines. Both companies sought to lower their cost structures as they worked through the bankruptcy process. WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? Our most significant purchases during the reporting period were made to increase the credit quality of the Fund and improve its margin of safety. Since we anticipated rising interest rates during the reporting period, we increased the Fund's exposure to bank loans and floating-rate notes. As interest rates rose, these assets reset their coupons and provided higher yields for the Fund. Significant sales during the reporting period included bonds that were tendered by their issuers. (A tender is a payment for bonds called prior to maturity.) Mergers and refinancings in the recent low-interest-rate and lenient credit environment encouraged companies to tender, or call, their bonds--a trend that added to the Fund's already higher-than-normal cash level. 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. 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 more than 100% and may generate taxable short-term capital gains. Funds that invest in bonds are subject to credit, inflation, and interest-rate risk and can lose principal value when interest rates rise. 1. See footnote on page 6 for more information on the Credit Suisse High Yield Index. 2. See footnote on page 6 for more information on Lipper Inc. 3. Performance figures for the year ended October 31, 2006, reflect nonrecurring reimbursements from affiliates. Without these reimbursements, total returns would have been lower. See Note 1 on page 6. www.mainstayfunds.com 9 HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD? The Fund's weightings are a result of our bottom-up security selection process. At the end of October 2006, the Fund's largest overweighted positions relative to the Credit Suisse High Yield Index were in financials and in energy: exploration & production. The Fund's investments in financial companies were primarily in issues that we felt would do well in a rising interest-rate environment. These included insurance companies, a check manufacturer, and a brokerage firm. At the end of the reporting period, the Fund held underweighted positions relative to the Index in the cable and manufacturing industries. The Fund had no exposure to the refining and consumer durables industries because companies in these areas typically do not meet our investment criteria.

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 High Yield Corporate Bond Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Class A shares commenced on January 3, 1995, Class B shares commenced on May 1, 1986, Class C shares commenced on September 1, 1998 and Class I 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 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I shares are not subject to a sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The four classes of 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 maximum current income through investment in a diversified portfolio of high yield debt securities. Capital appreciation is a secondary objective. The Fund also 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, as defined in Note 3, 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 trading of the New York Stock Exchange (generally 4:00 p.m. Eastern time). 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 each day the Fund is open for business ("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. Foreign currency forward contracts are valued at their fair market values determined on the basis of the mean between the last current bid and ask prices based on dealer or exchange quotations. Temporary cash investments acquired over 60 days prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At 28 MainStay High Yield Corporate Bond Fund October 31, 2006, the Fund held securities with a value of $48,140,729 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, as defined in Note 3, conclude that such events may have affected 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. Additionally, international equity securities are also fair valued whenever the movement of a particular index exceeds certain amounts. In such cases, the securities are fair valued by applying factors provided by a third party vendor in accordance with the Fund's policies and procedures. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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, accumulated net realized loss on investments and additional paid-in-capital arising from permanent differences; net assets at October 31, 2006, are not affected. <Table> <Caption> ACCUMULATED DISTRIBUTIONS IN EXCESS ACCUMULATED NET OF NET INVESTMENT REALIZED LOSS ON ADDITIONAL INCOME INVESTMENTS PAID-IN-CAPITAL $40,235,118 $(6,707,342) $(33,527,776) ----------------------------------------------------------- </Table> The reclassifications for the Fund are primarily due to return of capital, bond restructuring, premium amortization adjustments, paydown gain (loss), foreign currency gain (loss), interest write-offs and the reimbursement payment (See Note 11 on page 35). (D) 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 using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. www.mainstayfunds.com 29 NOTES TO FINANCIAL STATEMENTS (CONTINUED) (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) 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 the 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. For example 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. (I) 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 valuation date to credit loss in the event of a counterparty's failure to perform its obligations. (See Note 6 on page 34.) (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. 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. 30 MainStay High Yield Corporate Bond Fund (K) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 on page 34.) (L) 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 Fund does not have the right to demand that such securities be registered. Disposal of these securities may involve time-consuming negotiations and expenses and it may be difficult to obtain a prompt sale at an acceptable price. (See Note 6 on page 34.) (M) 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. (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 which could adversely impact the Fund.

All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust undertook a review of 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 $5.882 million to nine MainStay funds. The amount paid to the Fund was $814,000. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 12--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. www.mainstayfunds.com 35 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, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. KPMG LLP SIGNATURE Philadelphia, Pennsylvania December 21, 2006 36 MainStay High Yield Corporate Bond Fund BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's historical and continuing favorable investment performance record when compared over several time periods with groupings of funds having similar investment mandates. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher invest- www.mainstayfunds.com 37 ment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees recognized the large asset size of the Fund relative to other series of the Trust, and discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at asset levels above the breakpoint and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund's management fee rate had been reduced by the breakpoint schedule applicable to the Fund, and reviewed additional information regarding implementation of breakpoints for a fund having an asset base as large as that of the Fund. The Trustees reviewed information showing that the Fund's asset size had decreased based in part on investment trends that appeared to focus more heavily on other asset classes. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement 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, 2006, should be multiplied by 0.3% to arrive at the amount eligible for qualified dividend income, 78.9% to arrive at the amount eligible for qualified interest income and 1.8% for the corporate dividends received deduction.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as 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.

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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,095.30 $ 8.56 $1,016.90 $ 8.24 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,091.75 $12.50 $1,013.15 $12.03 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,091.85 $12.50 $1,013.15 $12.03 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,098.75 $ 5.34 $1,019.95 $ 5.14 - --------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,097.90 $ 5.92 $1,019.40 $ 5.70 - --------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,097.15 $ 7.24 $1,018.15 $ 6.97 - --------------------------------------------------------------------------------------------------------------------------- CLASS R3 SHARES $1,000.00 $1,095.25 $ 8.40 $1,017.05 $ 8.08 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

In the absence of waivers and/or reimbursements, expenses would have been higher. 8 MainStay International Equity Fund PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (COMPOSITION PIE CHART) <Table> Common Stocks 92.0 Short-Term Investments (collateral from securities lending 12.7 is 12.4%) Warrants 3.6 Liabilities in Excess of Cash and Other Assets (8.3) </Table> See Portfolio of Investments on page 12 for specific holdings within these categories.

Bhansali of MacKay Shields LLC HOW DID MAINSTAY INTERNATIONAL EQUITY FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay International Equity Fund returned 29.11% for Class A shares, 28.13% for Class B shares, and 28.15% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund's Class I shares returned 29.94%, Class R1 shares returned 29.76%, Class R2 shares returned 29.53%, and Class R3 shares returned 28.83%.(1) All share classes outperformed the 27.52% return of the MSCI EAFE(R) Index,(2) the Fund's broad-based securities-market index, for the 12-month period. All share classes also outperformed the 26.57% return of the average Lipper(3) international multi-cap core fund for the 12 months ended October 31, 2006.(4) WHAT FACTORS AFFECTED THE FUND'S RELATIVE PERFORMANCE? We attribute the Fund's performance to our bottom-up investment approach. We remained focused on the analysis of individual business models and sought to invest in quality companies. Our security selection is based on reasonable valuations rather than market perceptions. This approach pointed the Fund to companies with solid balance sheets and high returns on invested capital--a profile that began to see traction in the recent market environment. DURING THE REPORTING PERIOD, WHICH SECTORS WERE THE FUND'S STRONGEST CONTRIBUTORS AND WHICH SECTORS WERE THE WEAKEST? An overweighted position in diversified financials was the biggest contributor to the Fund's performance. Several names in the industry group benefited from consolidation among various stock markets. Performance in the technology hardware & equipment industry group was also strong. Telecommunication services and energy were the worst-performing industry groups during the reporting period. Companies in both of these market segments faced increased costs and competition, which put pressure on profit margins. DURING THE REPORTING PERIOD, WHICH FUND HOLDINGS DID PARTICULARLY WELL AND WHICH FUND HOLDINGS WERE WEAK? The strongest individual contributors to the Fund's performance included Man Group, a U.K. capital markets firm that benefited from a fast-growing asset management environment and strong fund perform-ance. TNT, a Netherlands-based logistics and mail company, also performed well. The company's earnings surpassed market expectations. Shares of Canon also advanced with rapid expansion in the digital camera market. The Fund's weakest holdings during the reporting period were all quality companies, including Canadian food & staples retailer Loblaw, U.S. supplemental insurance company AFLAC, and regulated electric-utility monopoly HongKong Electric. The Fund continues to hold these names. WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? The Fund added Nokian Renkaat, a Finland-based manufacturer of top-quality automobile tires. We increased the Fund's position in Mediaset, an Italian media firm that recently underperformed because of election results in Italy. We sold the Fund's position in Australian Gas Light at a profit after Alinta Limited attempted a hostile takeover and Australian Gas Light's shares rallied beyond what we believed to be their intrinsic value. We reduced the Fund's position in HongKong Electric because the natural monopoly was struggling under new regulatory challenges, including pressure to keep the electric tariff low. HOW WAS THE FUND POSITIONED RELATIVE TO THE MSCI EAFE(R) INDEX AT THE END OF THE REPORTING PERIOD? Our bottom-up investment approach directed the Fund toward consumer staples companies and higher-dividend-yielding utilities at the expense of industrials, materials, and telecommunication services stocks. As of October 31, 2006, the Fund held significantly overweighted positions relative to the 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 more than 100% and may generate taxable short-term capital gains. 1. Class R3 shares were first offered on April 28, 2006. 2. See footnote on page 7 for more information on the MSCI EAFE(R) Index. 3. See footnote on page 7 for more information on Lipper Inc. 4. Performance figures for the year ended October 31, 2006, reflect nonrecurring reimbursements from affiliates. Without these reimbursements, total returns would have been lower. See Note 1 on page 7. 10 MainStay International Equity Fund MSCI EAFE(R) Index in diversified financials, food & staples retailing, and media, as well as a more modestly overweighted position in health care. On the same date, the Fund was underweighted relative to the Index in telecommunication services, materials, and energy. The Fund held a market-weighted position in automobiles & components. WHERE HAVE YOU FOUND THE MOST COMPELLING OPPORTUNITIES? During the reporting period, we found fewer compelling investment opportunities among Japanese companies than we did in Europe and the rest of Asia. We did, however, find some Japanese businesses that met all of our criteria for ownership, and we modestly reduced the Fund's underweighted position 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 seven classes of shares. Class A shares commenced on January 3, 1995, Class B shares commenced on September 13, 1994, and Class C shares commenced on September 1, 1998, Class I shares, Class R1 shares and Class R2 shares commenced on January 2, 2004 and Class R3 shares commenced on April 28, 2006. 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I, Class R1, Class R2 and Class R3 shares are not subject to a sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The seven 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, Class R2 and Class R3 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, Class R2 and Class R3 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, Class R2 or Class R3 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 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. 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund held one security with a value of $609 that was 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 ask 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 22 MainStay International Equity Fund 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, as defined in Note 3, conclude that such events may have affected 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. Additionally, international equity securities are also fair valued whenever the movement of a particular index exceeds certain amounts. In such cases, the securities are fair valued by applying factors provided by a third party vendor in accordance with the Fund's policies and procedures. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are generally withheld at the source. (C) 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 undistributed net investment income, undistributed net realized gain on investments and additional paid-in-capital arising from permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED ACCUMULATED UNDISTRIBUTED UNDISTRIBUTED NET REALIZED ADDITIONAL NET INVESTMENT GAIN ON PAID-IN- INCOME INVESTMENTS CAPITAL $(4,285,200) $2,242,846 $2,042,354 ------------------------------------------- </Table> The reclassification for the Fund is primarily due to foreign currency gain (loss), reimbursement payment and utilization of earnings and profits on shareholder redemptions. (D) 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 using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. www.mainstayfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) (H) 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 5 on page 27.) (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. 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) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 27.) (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 any class. 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) 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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves 24 MainStay International Equity Fund as subadvisor to the Fund and 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 the 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 $500 million. In addition, 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 ordinary operating expenses (total annual 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, 1.60% 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 written expense limitation 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, 2006, this limit was 1.75% of the average daily net assets of the Class A shares. For the year ended October 31, 2006 the Manager earned fees from the Fund in the amount of $5,139,109. and waived its fees in the amount of $326,007. As of October 31, 2006, the amounts of waived fees that are subject to possible recoupment by the Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $33,294 $326,007 $359,301 - ----------------------------- </Table> * The expense limitation agreement became effective in 2005 and the recoupments will start to expire in 2008. Pursuant to the terms of a Subadvisory Agreement between NYLIM and the Subadvisor, the Manager pays the Subadvisor a monthly fee of 0.60% of the average daily net assets of the Fund.

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.

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 and Class C shares of the Fund. Pursuant to the Class R3 Plan, the Distributor receives a monthly fee from the Fund at the annual rate of 0.50% of the average daily net assets of the Fund's Class R3 shares, which is an expense of the Class R3 shares of the Fund for distribution or service activities as designated by the Distributor. Class I 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.

NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. The amount paid to the Fund was $772,000. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim 28 MainStay International Equity Fund periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. www.mainstayfunds.com 29 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, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. KPMG SIGNATURE Philadelphia, Pennsylvania December 21, 2006 30 MainStay International Equity Fund BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the nature of the Fund's investment program as managed by the Subadvisor, including certain aspects of its specific investment focus on parts of Europe, the apparent confidence of certain institutional investors in the investment program, the Fund's very recent and significant improvement in its shorter-term relative investment performance during a period of volatile markets, and the favorable effect of the recent performance on the longer-term relative performance data relating to the Fund. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense www.mainstayfunds.com 31 ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at asset levels above the breakpoint and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that, during the past year, the Fund's assets have increased to a level such that the management fee rate had been reduced by the breakpoint schedule applicable to the Fund. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to further lower the limit on the Fund's net expenses to a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. 32 MainStay International Equity 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, 2006 as to the federal tax status of dividends paid by the Fund during such fiscal year.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as 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. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense. 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.

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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $941.50 $ 7.34 $1,017.50 $ 7.63 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $938.15 $10.99 $1,013.75 $11.42 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $938.15 $10.99 $1,013.75 $11.42 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $943.35 $ 5.24 $1,019.65 $ 5.45 - --------------------------------------------------------------------------------------------------------------------------- CLASS R3 SHARES $1,000.00 $940.70 $ 7.92 $1,016.90 $ 8.24 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

In the absence of waivers and/or reimbursements, expenses would have been higher. www.mainstayfunds.com 7 PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> Common Stocks 93.1 Short-Term Investments (collateral from securities lending 24.5 is 18.1%) Liabilities in Excess of Cash and Other Assets (17.6) </Table> See Portfolio of Investments on page 11 for specific holdings within these categories.

Spelman of MacKay Shields LLC HOW DID MAINSTAY MID CAP GROWTH FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay Mid Cap Growth Fund returned 9.39% for Class A shares, 8.83% for Class B shares, and 8.64% for Class C shares for the 12 months ended October 31, 2006. Over the same period, Class I shares returned 9.89% and Class R3 shares returned 9.11%.(1) All share classes underperformed the 14.51% return of the Russell Midcap(R) Growth Index,(2) the Fund's broad- based securities-market index, for the 12-month period. All share classes also underperformed the 11.51% return of the average Lipper(3) mid-cap growth fund for the 12 months ended October 31, 2006. WHAT FACTORS HAD THE GREATEST IMPACT ON THE FUND'S RELATIVE PERFORMANCE? During the reporting period, the Fund's underperformance relative to its peers and the Russell Midcap(R) Growth Index resulted primarily from ineffective individual stock selection in the industrials, financials, and health care sectors. The Fund's overweighted positions in the materials and energy sectors contributed positively to the Fund's performance relative to the Index, as did an underweighted position in the information technology sector. DURING THE REPORTING PERIOD, WHICH STOCKS WERE STRONG PERFORMERS AND WHICH ONES WERE WEAK? There were several strong performers. Specialty metals producer Allegheny Technologies benefited from solid end-market demand, higher selling prices, and improved productivity. Apparel retailer American Eagle Outfitters advanced on record sales and earnings. Las Vegas Sands benefited from strong gaming revenue, increased market share in Macao, and the popularity of Las Vegas as a vacation destination. Garmin, a leader in GPS-enabled navigation and communications devices, advanced on strong sales and profits. Diversified equipment manufacturer Terex saw strong earnings from operations and benefited from the sale of the company's interest in Tetra, a Czech trucking company. Terex's gains were partially offset by increases in working capital and other factors. During the reporting period, independent petroleum refiner and marketer Holly benefited from rising prices for refined products. Major detractors from the Fund's performance included specialty retailer Chico's FAS, which suffered from weaker-than-expected same-store sales in recent months. Leading coal producers Massey Energy and Arch Coal weakened when mild weather and an economic slowdown sliced into electricity demand. Omnicare, a leading provider of pharmaceutical care for the elderly, saw its stock price decline because of litigation with UnitedHealth Group and a mislabeling mishap that led to a product recall. A slowdown in the housing market hurt performance at building-products company Simpson Manufacturing and at homebuilder and mortgage-finance company The Ryland Group. WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? The Fund initiated new positions in Internet services company Akamai Technologies, steel producer Oregon Steel Mills, clothing company Phillips Van Heusen, entertainment and telecommunications company Cablevision Systems, and property & casualty insurance holding company W.R. Berkley. The Fund sold its positions in Chico's FAS, Massey Energy, Omnicare, Simpson Manufacturing, and The Ryland Group, all of which detracted from the Fund's performance during the reporting period. We also eliminated a position in health care products manufacturer Cooper Companies when the stock under-performed. HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE DURING THE REPORTING PERIOD? During the reporting period, the Fund increased its weightings relative to the Russell Midcap(R) Growth Index in information technology and materials. The Fund decreased its weightings in the energy, consumer discretionary, and health care sectors. Mid-capitalization companies are generally less established and their stocks may be more volatile and less liquid than the securities of large companies. The principal risk of growth stocks is that investors expect growth companies to increase their earnings at a certain rate that is generally higher than the rate expected for nongrowth companies. If these expectations are not met, the market price of the stock may decline significantly, even if earnings showed an absolute increase. The Fund may experience a portfolio turnover rate of more than 100% and may generate taxable short-term capital gains. 1. Class R3 shares were first offered on April 28, 2006. 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 Mid Cap Growth Fund (the "Fund"), a diversified fund. The Fund currently offers five classes of shares. Class A shares, Class B shares and Class C shares commenced on January 2, 2001, Class I shares commenced on March 29, 2005 and Class R3 shares commenced on April 28, 2006. 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I shares and Class R3 shares are not subject to sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The five 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 R3 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. Class R3 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 R3 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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 rear reclassifications between accumulated net investment income and additional paid-in-capital arising from permanent differences; net assets at October 31, 2006, are not affected. <Table> <Caption> ACCUMULATED NET ADDITIONAL INVESTMENT PAID-IN- INCOME CAPITAL $2,108,907 $ (2,108,907) --------------------------------- </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. (D) 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 using the effective interest rate method. 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 23.) (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager.

In addition the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total operating expenses (total annual 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, 1.50% 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $1,543,360 and waived its fees in the amount of $95,745.

Pursuant to the Class R3 Plan, the Distributor receives a monthly fee from the Fund at the annual rate of 0.50% of the average daily net assets of the Fund's Class R3 shares, which is an expense of the Class R3 shares of the Fund for distribution or service activities as designated by the Distributor. 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 R3 shares. Under the terms of this plan, Class R3 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 R3 shares.

NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 24 MainStay Mid Cap Growth 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 Growth Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 www.mainstayfunds.com 25 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's excellent performance over the medium- and longer-term and its weaker recent performance. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees 26 MainStay Mid Cap Growth Fund discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoints that would reduce the Fund's management fee at asset levels above the breakpoints, and the fact that the breakpoints were intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees acknowledged the Fund's recent asset growth but noted that the Fund had not reached the asset level at which breakpoints would reduce the Fund's management fee rate. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to maintain the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. www.mainstayfunds.com 27 PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD A description of the policies and procedures that NYLIM uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by visiting the Fund's website at www.mainstayfunds.com; or (ii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

All rights reserved. SEC File Number: 811-04550 NYLIM-A09806 (RECYCLE LOGO) MS377-06 MSMG11-12/06 11 (MAINSTAY INVESTMENTS LOGO) MAINSTAY MONEY MARKET FUND Message from the President and Annual Report October 31, 2006 MESSAGE FROM THE PRESIDENT Most stock and bond markets around the world provided positive total returns during the 12 months ended October 31, 2006. International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense. Prior to 9/1/98, the performance of Class C shares includes the historical performance of Class B shares. 1. As of 10/31/06, MainStay Money Market Fund had an effective 7-day yield of 4.71% and a 7-day current yield of 4.59% 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 4.44% and the current 7-day yield would have been 4.42%. These 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,022.90 $3.57 $1,021.50 $3.57 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,022.90 $3.57 $1,021.50 $3.57 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,022.90 $3.57 $1,021.50 $3.57 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1. Expenses are equal to the Fund's annualized expense ratio of each class (0.70% for Class A, Class B and Class C) multiplied by the average account value over the period, divided by 365 and multiplied by 184 (to reflect the one-half year period). In the absence of waivers and/or reimbursements, expenses would have been higher. 6 MainStay Money Market Fund PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> Commercial Paper 44.8 Federal Agencies 35.2 Corporate Bonds 14.4 Medium-Term Notes 3.3 Foreign Government Bonds 1.1 Certificate of Deposit 0.8 Asset-Backed Security 0.4 Liabilities in Excess of Cash and Other Assets (0.0) </Table> * Less than one-tenth of a percent.

As of October 31, 2006, MainStay Money Market Fund Class A, Class B, and Class C shares had a 7-day current yield of 4.59% and a 7-day effective yield of 4.71%. For the 12 months ended October 31, 2006, MainStay Money Market Fund returned 4.18% for Class A, Class B, and Class C shares. All share classes outperformed the 3.99% return of the average Lipper(1) money market fund for the 12 months ended October 31, 2006. WHAT FACTORS CONTRIBUTED TO THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? According to preliminary estimates by the Bureau of Economic Analysis, real gross domestic product (GDP) increased by 3.05% during the four quarters ended September 30, 2006. The economy grew at a robust 5.6% seasonally adjusted annualized rate in the first quarter of 2006. Since then, growth has moderated, in part because of the slowdown in the housing sector. Real gross domestic product increased at a 2.6% seasonally adjusted annualized rate in the second quarter and by 2.2% in the third quarter. Residential investment declined at an 18.0% seasonally adjusted annualized rate in the third quarter, the fourth consecutive quarter in which the sector has made a negative contribution to GDP growth. At the end of October 2005, the targeted federal funds rate was 3.75%. The Federal Open Market Committee (FOMC) met nine times during the 12 months ended October 31, 2006, and it raised the targeted federal funds rate by 25 basis points at each of the first six meetings. (A basis point is one-hundredth of a percentage point.) That brought the federal funds target rate to 5.25% in June 2006. Since then, the FOMC has opted to leave the federal funds target unchanged. Another significant Federal Reserve development came in February 2006, when Dr. Bernanke succeeded Dr. Greenspan as chairman of the Federal Reserve Board of Governors. Robust economic growth in the first quarter of 2006 and a string of higher-than-expected monthly inflation data contributed to a rise Treasury yields across the maturity spectrum. Yields climbed above 5% in the spring of 2006. The deceleration in economic growth during the summer prompted a sharp decline in yields and raised investors' expectations of interest-rate cuts. The yield on the three-month Treasury bill was 5.08% at the end of October 2006, 120 basis points higher than a year earlier, while three-month LIBOR(2) was 5.37% at the end of October, up from 5.26% a year ago. HOW DID THE FUND INVEST DURING THE REPORTING PERIOD? The Fund's returns were boosted by the Federal Reserve's decision to raise the targeted federal funds rate from 3.75% to 5.25%. As a result, the Fund's lower-yielding investments were reinvested in higher-yielding securities as they matured. The Fund invested in securities issued by U.S. government sponsored agencies such as Fannie Mae, Freddie Mac, the Federal Home Loan Bank, and TVA (Tennessee Valley Authority), as well as first-tier securities issued by finance, insurance, brokerage, and industrial companies as well as banks and bank holding companies. WHAT WAS THE FUND'S DOLLAR-WEIGHTED AVERAGE MATURITY AT THE END OF THE REPORTING PERIOD? As of October 31, 2006, the dollar-weighted average maturity of the Fund was approximately 62 days. WHAT OTHER EVENTS AFFECTED THE MONEY MARKET DURING THE REPORTING PERIOD? Expectations of short-term rate cuts in the first half of 2007 have receded following the release of the October 2006 Labor Department report. The report revealed that 470,000 new jobs were created during the August-October period and that the unemployment rate fell to 4.4% in October.

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 commenced on January 3, 1995, Class B shares commenced on May 1, 1986 and Class C shares commenced on September 1, 1998. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The three classes of 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. 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (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 accounting principles generally accepted in the United States of America. The following table discloses the current year reclassifications between accumulated undistributed net investment income, accumulated net realized gain on investment and additional paid-in-capital arising from permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED ACCUMULATED NET REALIZED UNDISTRIBUTED NET GAIN ON ADDITIONAL INVESTMENT INCOME INVESTMENTS PAID-IN-CAPITAL $6,984 $(6,979) $(5) ---------------------------------------------------------- </Table> The reclassifications for the Fund are primarily due to distribution reclasses and miscellaneous adjustments. (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) are allocated to separate classes of shares based upon their relative net 18 MainStay Money Market Fund 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. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. 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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and 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 the 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. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $2,199,024 and waived its fees in the amount of $1,058,259. As of October 31, 2006, the amounts of waived fees that are subject to possible recoupment by the Investment Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $232,330 $1,058,259 $1,290,589 ---------------------------------- </Table> * The expense limitation agreement became effective in 2005 and the recoupments will start in 2008.

To the extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (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 www.mainstayfunds.com 19 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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, 2006, in the amount of $445,861. (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 pursuant to which it performs certain services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2006, amounted to $1,501,404. (D) NON-INTERESTED TRUSTEES FEES. For the year ended October 31, 2006, Non-Interested Trustees were paid an annual retainer of $45,000, $2,000 for each Board meeting attended, $1,000 for each Committee meeting attended and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee received an additional annual retainer of $20,000. The Audit and Compliance Committee Chairman received 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 received an additional $1,000 for each meeting of the respective committee meetings attended. In addition, each Non-Interested Trustee received $1,000 for attending meetings of the Non-Interested Trustees held in advance of or in connection with Board/Committee meetings.

All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust undertook a review of 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 $5.882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 8--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 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 Money Market Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 22 MainStay Money Market Fund BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Manager, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's mid-range performance relative to certain measures over various periods of time and the sensitivity of money market funds' relative net performance to their expense ratios. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of www.mainstayfunds.com 23 shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoints that would reduce the Fund's management fee at asset levels above the breakpoints, and the fact that the breakpoints were intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund's management fee rate had been reduced by the breakpoint schedule applicable to the Fund. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other registered money market fund clients of the Manager and Subadvisor, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to maintain a limit on the Fund's net expenses at a certain level. The Trustees considered other actions by the Manager within the last year to reduce other expenses of the Fund. 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. 24 MainStay Money Market 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, 2006) as to the federal tax status of dividends paid by the Fund during such fiscal year. Accordingly, the Fund paid long-term capital gain distributions of $6,979. The dividends paid by the Fund during the fiscal year ended October 31, 2006, should be multiplied by 100% to arrive at the amount eligible for qualified interest income. In January 2007, shareholders will receive on IRS Form 1099-DIV or substitute Form 1099 the federal tax status of the distributions received by shareholders in calendar year 2006. The amounts that will be reported on such 1099-DIV will be the amounts you are to use on your federal income tax return and will differ from the amounts which we must report for the Fund's fiscal year ended October 31, 2006.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. Sincerely, /s/ CHRISTOPHER O. BLUNT Christopher O.

Class A shares are sold with a maximum initial sales charge of 4.5% 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 0.5%. 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 0.5%. Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense. Prior to 9/1/98 (for Class C shares) and 12/31/03 (for Class I shares), performance for Class C and Class I shares includes the historical performance of Class B shares adjusted to reflect the applicable sales charge (or CDSC) and fees and expenses for Class C and 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,044.45 $4.59 $1,020.55 $4.53 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,043.20 $5.87 $1,019.30 $5.80 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,043.20 $5.87 $1,019.30 $5.80 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1. Expenses are equal to the Fund's annualized expense ratio of each class (0.89% for Class A, 1.14% for Class B and Class C) multiplied by the average account value over the period, divided by 365 and, multiplied by 184 (to reflect the one-half year period). In the absence of waivers and/or reimbursements, expenses would have been higher. www.mainstayfunds.com 7 PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> <Caption> LIABILITIES IN EXCESS SHORT-TERM CUMULATIVE OF CASH AND OTHER LONG-TERM MUNICIPAL BONDS INVESTMENTS PREFERRED STOCK FUTURES CONTRACTS ASSETS - ------------------------- ----------- --------------- ----------------- --------------------- 90.7 7.4 3.8 0.0* (1.9) </Table> * Less than one-tenth of a percent.

Excluding all sales charges, MainStay Tax Free Bond Fund returned 5.43% for Class A shares, 5.16% for Class B shares, and 5.16% for Class C shares for the 12 months ended October 31, 2006. All share classes underperformed the 5.75% return of the Lehman Brothers(R) Municipal Bond Index,(1) the Fund's broad- based securities-market index, for the 12-month period. Class A shares outperformed--and Class B and Class C shares underperformed--the 5.41% return of the average Lipper(2) general municipal debt fund for the 12 months ended October 31, 2006.(3) WHAT FACTORS IN THE MUNICIPAL BOND MARKET AFFECTED THE FUND DURING THE 12-MONTH REPORTING PERIOD? Shorter- and longer-term municipal yields diverged during the reporting period. Yields on securities with shorter maturities closely tracked the rising targeted federal funds rate, while yields on 10- and 30-year bonds declined. At the end of the reporting period, the slope of the municipal yield curve flattened dramatically as the spread(3) between two-year and 30-year municipal bond yields narrowed. A variety of factors contributed to the shallowness of the yield curve, including the market's anticipation of a cooling economy and the Federal Reserve's resolve to keep inflation in check. WHAT WAS THE FUND'S DURATION STRATEGY DURING THE REPORTING PERIOD? During the 12-month reporting period, we kept the Fund's duration longer than that of the Lehman Brothers(R) Municipal Bond Index. Our view was that the Federal Reserve would eventually pause from raising short-term interest rates. We felt that a slow-ing housing market would make it more difficult for consumers to extract equity from their homes, which, in turn, would weaken the broader economy. Unfortunately, interest rates rose higher than we anticipated from March through June, which detracted from performance. The Fund recouped these losses, however, and closed the year with a net gain from duration as our economic thesis gained credibility and interest rates fell sharply in the third quarter of 2006. WHAT POSITIONING DECISIONS AFFECTED THE FUND'S PERFORMANCE? As yields declined, investors were drawn to sectors that offered additional yield. The Fund's overweighted position in A-rated health care securities helped performance when spreads contracted during the reporting period. We added California Healthcare for Kaiser Permanente bonds to take advantage of the hospital's consistent profitability. We liquidated a Wisconsin Wheaton Healthcare holding when profits declined and leverage increased. We completed the sale before the bonds were downgraded. In the housing sector, we purchased a Chicago Housing Authority issue backed by federal government subsidies to improve public housing. We continued to hold preferred stock in Charter Mac Equity Issuer Trust, which maintains a portfolio of multifamily housing units. Although single-family home construction slowed, rental units remained scarce in many parts of the country, which helped the Fund's housing positions. Transactions during the reporting period focused on adding incremental yield in sectors--such as health care, housing, and industrial development bonds--that offered appropriate compensation for any additional risk. We also added new credits, such as Tennessee Energy Acquisition, that had solid revenues and attractive spreads. We reduced exposure to electric utilities, prerefund-ed issues, and lease revenue bonds because they offered little in terms of incremental yields when compared with other credits. The Fund was underweighted in tobacco-settlement bonds, since they were trading at tight spreads and remained subject to a variety of legal risks. We also reduced exposure to the five-year maturity range in favor of 15-year and 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. The Fund may experience a portfolio turnover rate of more than 100% and may generate taxable short-term capital gains. 1.

Performance figures for the year ended October 31, 2006, reflect nonrecurring reimbursements from affiliates. Without these reimbursements, total returns would have been lower. See Note 1 on page 6. 4. 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. www.mainstayfunds.com 9 longer maturities, which offered incremental yield and greater performance potential. These changes enhanced the Fund's results as credit spreads tightened and longer maturities outperformed short maturities after the end of the first quarter of 2006. HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD? As of October 31, 2006, the Fund was overweighted relative to the Lehman Brothers(R) Municipal Bond Index in health care, housing, and industrial development bonds. The Fund was underweighted in prerefunded, education, and lease revenue bonds. The opinions expressed are those of the portfolio managers as of the date of this report and are subject to change.

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 commenced on January 3, 1995, Class B shares commenced on May 1, 1986 and Class C shares commenced 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 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The three 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 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, as defined in Note 3, 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 trading of the New York Stock Exchange (generally 4:00 p.m. Eastern time). 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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund did not hold securities that were valued in such a manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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 reclassification between accumulated net realized gain and additional 22 MainStay Tax Free Bond Fund paid-in-capital, arising from permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED ADDITIONAL NET REALIZED PAID-IN- LOSS CAPITAL $ (49,999) $49,999 ------------------------- </Table> The reclassification for the Fund is primarily due to the reimbursement payment (See Note 9 on page 26). (D) 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, using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) 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 price of the underlying security or foreign currency increase. 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. 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. When writing a covered call option, the Fund, in return for the premium on the option, gives up the opportunity to profit from a price increase in the underlying securities above the exercise price, but, as long as the obligation as the writer continues, has retained the risk of loss should the price of the underlying security decline. 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. 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. www.mainstayfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) (I) 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. (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and 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 the 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 voluntarily agreed to waive its management fee by 0.15% to 0.45% on assets up to $1.0 billion, and 0.40% on assets in excess of $1.0 billion. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total operating expenses (total annual 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, 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $1,564,622 and waived its fees in the amount of $482,508. As of October 31, 2006, the amounts of waived fees that are subject to possible recoupment by the Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $30,280 $91,353 $121,633 - ------------------------------------------------------------- </Table> *The expense limitation agreement became effective in 2005 and the recoupments will start to expire in 2008. Pursuant to the terms of a Subadvisory Agreement between NYLIM and the Subadvisor, 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 24 MainStay Tax Free Bond Fund to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (B) PAYMENTS FROM AFFILIATES. NYLIM reimbursed or paid all expenses relating to the Board of Trustees' review of certain shareholder trading matters as described below in the footnote relating to "Other Matters." (See Note 9 on page 26). The total costs associated with the Board of Trustees' review were approximately $849,975 and included payments to certain third party service providers. The amount that was reimbursed to the Tax Free Bond Fund was $35,010. Additional payments were made by affiliates relating to the shareholder trading matters. Further discussion regarding these payments by affiliates can be found below in the footnote relating to "Other Matters." (C) 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 and 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. (D) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $21,300 for the year ended October 31, 2006. 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 $715, $69,471 and $1,238, respectively, for the year ended October 31, 2006. (E) 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 pursuant to which it performs certain services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2006, amounted to $249,669. (F) NON-INTERESTED TRUSTEES FEES. For the year ended October 31, 2006, Non-Interested Trustees were paid an annual retainer of $45,000, $2,000 for each Board meeting attended, $1,000 for each Committee meeting attended and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee received an additional annual retainer of $20,000. The Audit and Compliance Committee Chairman received 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 received an additional $1,000 for each meeting of the respective committee meetings attended. In addition, each Non-Interested Trustee received $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. (G) CAPITAL. At October 31, 2006, New York Life and its affiliates held shares of the Fund with the following values and percentages of net assets as follows: <Table> Class A $ 52,277 0.0*% - --------------------------------------------------------------- Class C 106 0.0* - --------------------------------------------------------------- </Table> * Less than one tenth of a percent. (H) OTHER. Pursuant to an Amended and Restated Management Agreement between the Fund and NYLIM, the cost of legal services provided to the Fund by the Office of the General Counsel of NYLIM are payable directly by the Fund. For the year ended October 31, 2006, these fees, which are included in Professional fees shown on the Statement of Operations, were $7,417. 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 www.mainstayfunds.com 25 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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.

NOTE 4--FEDERAL INCOME TAX: The Fund has maintained a year end of December 31 for federal income tax purposes. As of October 31, 2006, 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 $1,754 $(29,012,205) $(230,200) $13,038,242 $(16,202,409) -------------------------------------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to the tax treatment of futures transactions. The other temporary differences are primarily due to distribution payable. At October 31, 2006, for federal income tax purposes, capital loss carryforwards of $29,012,205 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 $ 4,964 2008 15,453 2011 8,117 2012 478 ------------------------------------------- $29,012 ------------------------------------------- </Table> The Fund utilized $3,032,928 of capital loss carryforwards during the year ended October 31, 2006.

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 6--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. These funds paid a commitment fee, at an annual rate of .070%, up to September 6, 2006 at which time the rate changed to .060% 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 made or outstanding on the line of credit during the year ended October 31, 2006. NOTE 7--PURCHASES AND SALES OF SECURITIES (IN 000'S): During year ended October 31, 2006, purchases and sales of securities, other than short-term securities, were $143,458 and $159,515, respectively.

All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust undertook a review of 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 $5.882 million to nine MainStay funds. The amount paid to the Fund was $50,000. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 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 Tax Free Bond Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 28 MainStay Tax Free Bond Fund BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, underperformance when compared over various time periods with groupings of funds having similar mandates, and measures that the Subadvisor had taken with respect to enhancing its credit analysis processes. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher invest- www.mainstayfunds.com 29 ment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at asset levels above the breakpoint and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund had not reached the asset level at which the breakpoint would reduce the Fund's management fee rate. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to waive a certain portion of its management fee, and to maintain a limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement 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, 2006 as attributable to interest income from Tax Exempt Municipal Bonds.

SEC File Number: 811-04550 NYLIM-AO9806 (RECYCLE LOGO) MS377-06 MST11-12/06 13 (MAINSTAY INVESTMENTS LOGO) MAINSTAY TOTAL RETURN FUND Message from the President and Annual Report October 31, 2006 MESSAGE FROM THE PRESIDENT Most stock and bond markets around the world provided positive total returns during the 12 months ended October 31, 2006. International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. Sincerely, /s/ CHRISTOPHER O. BLUNT Christopher O.

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. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense.

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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,024.55 $6.07 $1,019.05 $6.06 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,020.70 $9.88 $1,015.30 $9.85 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,020.70 $9.88 $1,015.30 $9.85 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,026.40 $3.78 $1,021.30 $3.77 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

In the absence of waivers and/or reimbursements, expenses would have been higher. www.mainstayfunds.com 7 PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> <Caption> SHORT- TERM INVESTMENTS (COLLATERAL U.S. FROM GOVERNMENT SECURITIES & LENDING MORTGAGE- ASSET- COMMON FEDERAL IS CORPORATE FOREIGN BACKED CONVERTIBLE BACKED INVESTMENT STOCKS AGENCIES 9.3%) BONDS BONDS SECURITIES BONDS SECURITIES COMPANY - ------ ---------- ----------- --------- ------- ---------- ----------- ---------- ---------- 62 23.1 13.2** 5.1 2.6 2.1 1.2 1.1 0.2 <Caption> LIABILITIES IN EXCESS OF LOAN CASH ASSIGNMENTS CONVERTIBLE AND & MUNICIPAL YANKEE PREFERRED PREFERRED OTHER PARTICIPATIONS BOND BONDS STOCKS STOCK ASSETS -------------- --------- ------ ----------- --------- ----------- 0.1 0.1 0.1 0.0* 0.0* (10.9) </Table> * Less than one-tenth of a percent. ** Includes 0.5% in Investment Company securities.

Spelman, Richard A. Rosen, CFA, Joseph Portera, and Gary Goodenough of MacKay Shields LLC HOW DID MAINSTAY TOTAL RETURN FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay Total Return Fund returned 10.53% for Class A shares, 9.74% for Class B shares, and 9.69% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund's Class I shares returned 11.11%. All share classes underperformed the 11.62% return of the Total Return Core Composite Index,(1) the Fund's broad-based securities-market index, for the 12-month period. All share classes also underperformed the 12.47% return of the average Lipper(2) mixed-asset target allocation growth fund for the 12 months ended October 31, 2006.(3) WHAT WERE THE STRONGEST-PERFORMING SECTORS IN THE EQUITY PORTION OF THE FUND DURING THE REPORTING PERIOD AND WHICH SECTORS WERE THE WEAKEST? The Fund invests in growth and value stocks. Effective stock selection in the industrials, energy, and materials sectors made the greatest positive contributions to the Fund's results relative to the Russell 1000(R) Index,(4) the equity component of the Fund's broad-based securities-market index, the Total Return Core Composite Index. The sectors that detracted the most from relative performance in the equity portion of the Fund were financials, telecommunication services, and consumer discretionary. DURING THE REPORTING PERIOD, WHICH STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S PERFORMANCE AND WHICH STOCKS DETRACTED? Among the Fund's strongest-performing equity holdings was mining company Inco, which advanced on rising nickel prices and a series of acquisition bids. Another strong equity holding was Comcast, which benefited from its "triple-play" offering of video, high-speed Internet service, and phone service. Other positive contributors to equity performance included Bank of America in the financials sector, Pfizer in the pharmaceuticals industry, and Transocean in the energy sector. The biggest detractors from relative performance in the equity portion of the Fund were in the telecommunication services sector, largely because of weakness at wireless carrier Sprint Nextel. Other equity holdings that hurt the Fund's relative performance included UnitedHealth Group, Omnicare, Yahoo!, and BJ Services. WERE THERE ANY SIGNIFICANT EQUITY PURCHASES OR SALES DURING THE REPORTING PERIOD? In the information technology sector, the Fund initiated new positions in Akamai Technologies and Cisco Systems during the reporting period. In the consumer discretionary sector, we added Comcast and News Corp. The Fund sold its position in Inco when the company's shares moved to our price target. The Fund also eliminated its positions in Yahoo!, eBay, D.R. Horton, Chico's FAS, and Lennar. We reduced the Fund's positions in Comcast and Transocean as these stocks neared our price targets. We also reduced the Fund's exposure to Sprint Nextel in light of the company's disappointing acquisition integration. HOW DID YOU POSITION THE BOND PORTION OF THE FUND DURING THE REPORTING PERIOD? We maintained an overweighted position in bonds relative to the Total Return Core Composite Index. We particularly favored mortgage-backed and asset-backed securities, which we expected to perform well for two reasons. First, interest rates clung to a rather narrow range during the reporting period. Second, collateral--or the properties or assets used to secure loans or other credits--remained generally healthy. The latter was especially true of commercial 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 principal risk of investing in value stocks is that they may never reach what the portfolio manager believes is their full value or they may even go down in value. The principal risk of growth stocks is that investors expect growth companies to increase their earnings at a certain rate that is generally higher than the rate expected for nongrowth companies. If these expectations are not met, the market price of the stock may decline significantly, even if earnings showed an absolute increase. The Fund may experience a portfolio turnover rate of more than 100% and may generate taxable short-term capital gains. Funds that invest in bonds are subject to credit, inflation, and interest-rate risk and can lose principal value when interest rates rise. 1.

We expected slower price appreciation in the housing market to help residential mortgage-backed securities, since borrowers would have fewer refinancing options and underlying future cash flows would tend to stabilize. DID THE FUND'S BOND-SECTOR WEIGHTINGS CHANGE DURING THE REPORTING PERIOD? Throughout the reporting period, we maintained overweighted positions in securitized holdings, including mortgage-backed and asset-backed securities. The Fund's positions in commercial mortgage-backed securities and asset-backed securities added value. The Fund's overweighted position in Ginnie Mae securities proved less successful. Reduced demand from foreign investors caused the price of these residential mortgage-backed securities to decline. We reduced the Fund's exposure to Ginnie Mae securities by the end of October 2006.

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 commenced on January 3, 1995, Class B shares commenced on December 29, 1987, Class C shares commenced on September 1, 1998 and Class I 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I shares are not subject to a sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The four classes of 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, as defined in Note 3, 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 trading of the New York Stock Exchange (generally 4:00 p.m. Eastern time). 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund did not hold securities 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. 28 MainStay Total Return Fund Should the Manager or Subadvisor, as defined in Note 3, conclude that such events may have affected 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. Additionally, international equity securities are also fair valued whenever the movement of a particular index exceeds certain amounts. In such cases, the securities are fair valued by applying factors provided by a third party vendor in accordance with the Fund's policies and procedures. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are generally withheld at the source. (C) 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 on investments and additional paid-in-capital, arising from permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED UNDISTRIBUTED ACCUMULATED NET ADDITIONAL NET INVESTMENT REALIZED GAIN ON PAID-IN INCOME INVESTMENTS CAPITAL $65,026 $(167,026) $102,000 ---------------------------------------------- </Table> The reclassifications for the Fund are primarily due to the reimbursement payments (See Note 11 on page 34), premium amortization adjustments and paydown gain (loss). (D) 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 using the effective interest rate method. Discounts and premiums on securities purchased, other than short-term securities, for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) 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 www.mainstayfunds.com 29 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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 price of the underlying security or foreign currency increase. 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. 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. When writing a covered call option, the Fund, in return for the premium on the option, gives up the opportunity to profit from a price increase in the underlying securities above the exercise price, but, as long as the obligation as the writer continues, has retained the risk of loss should the price of the underlying security decline. 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. 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. (I) 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 the 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. For example, 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. (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. 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) 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 30 MainStay Total Return Fund 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, the Fund forgoes principal and interest on the securities. The 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 liquid assets 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. (L) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 on page 33.) (M) 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 Fund does not have the right to demand that such securities be registered. Disposal of these securities may involve time-consuming negotiations and expenses and it may be difficult to obtain a prompt sale at an acceptable price. (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and 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 the 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. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total operating expenses (total annual 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, 1.19% 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $4,669,869 and waived its fees in the amount of $1,037,949. www.mainstayfunds.com 31 NOTES TO FINANCIAL STATEMENTS (CONTINUED) As of October 31, 2006, the amounts of waived fees that are subject to possible recoupment by the Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $177,401 $1,037,949 $1,215,350 ----------------------------------- </Table> * The expense limitation agreement became effective in 2005 and the recoupments will start to expire in 2008. Pursuant to the terms of a Subadvisory Agreement between NYLIM and the Subadvisor, 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. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (B) PAYMENTS FROM AFFILIATES. NYLIM reimbursed or paid all expenses relating to the Board of Trustees' review of certain shareholder trading matters as described below in the footnote relating to "Other Matters." (See Note 11 on page 34.) The total costs associated with the Board of Trustees' review were approximately $849,975 and included payments to certain third party service providers. The amount that was reimbursed to the Fund was $79,841. Additional payments were made by affiliates relating to the shareholder trading matters. Further discussion regarding these payments by affiliates can be found below in the footnote relating to "Other Matters." (C) 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 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 and Class C shares of the Fund.

NOTE 11--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. The amount paid to the Fund was $102,000. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 12--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 34 MainStay Total Return 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 Total Return Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 www.mainstayfunds.com 35 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's underperformance over the medium- and longer-term, its recent improved investment performance relative to that of funds having similar investment mandates, and its improved risk-adjusted returns. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of 36 MainStay Total Return Fund shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoints that would reduce the Fund's management fee at asset levels above the breakpoints, and the fact that the breakpoints were intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees reviewed information showing that the Fund's asset level had decreased over the past several years but noted that the Fund's management fee rate had been reduced by the breakpoint schedule applicable to the Fund. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to maintain a limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement 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, 2006) as to the federal tax status dividends paid by the Fund during such fiscal year. Accordingly, the Fund paid long-term capital gain distributions of $28,780,000. The dividends paid by the Fund during the fiscal year ended October 31, 2006, should be multiplied by 72.1% to arrive at the amount eligible for qualified dividend income, 36.6% to arrive at the amount eligible for qualified interest income and 77.6% for the corporate dividends received deduction. In January 2007, shareholders will receive on IRS Form 1099-DIV or substitute Form 1099 the federal tax status of the distributions received by shareholders in calendar year 2006. The amounts that will be reported on such 1099-DIV will be the amounts you are to use on your federal income tax return and will differ from the amounts which we must report for the Fund's fiscal year ended October 31, 2006.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. Sincerely, /s/ CHRISTOPHER O. BLUNT Christopher O.

The Russell 1000(R) Value Index is an unmanaged index that measures the performance of those Russell 1000(R) companies with lower price-to-book ratios and lower forecasted growth values. The Russell 1000(R) Index 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 1000(R) Value Index is considered to be the Fund's broad-based securities-market index for comparison purposes.

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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,044.95 $6.03 $1,019.15 $5.95 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,041.00 $9.88 $1,015.40 $9.75 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,041.00 $9.88 $1,015.40 $9.75 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,047.55 $3.87 $1,021.25 $3.82 - --------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,046.65 $4.38 $1,020.75 $4.33 - --------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,045.40 $5.67 $1,019.50 $5.60 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Rosen, CFA, of MacKay Shields LLC HOW DID MAINSTAY VALUE FUND PERFORM RELATIVE TO ITS BENCHMARK AND ITS PEERS DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay Value Fund returned 17.30% for Class A shares, 16.44% for Class B shares, and 16.44% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund's Class I shares returned 17.78%, Class R1 shares returned 17.67%, and Class R2 shares returned 17.46%. All share classes underperformed the 21.46% return of the Russell 1000(R) Value Index,(1) the Fund's broad-based securities-market index, for the 12-month period. With the exception of Class I shares, all share classes underperformed the 17.73% return of the average Lipper(2) large-cap value fund for the 12 months ended October 31, 2006.(3) WHICH FUND HOLDINGS WERE PARTICULARLY STRONG DURING THE REPORTING PERIOD? Despite their volatility, energy prices remained reasonably high, which benefited several of the Fund's energy holdings, including integrated pro- ducers ExxonMobil and Chevron. Offshore driller Transocean advanced on increasing demand for its high-end rigs. We added to the Fund's position in Chevron when the company's shares weakened, and we reduced the Fund's position in Transocean as the stock neared our price target. In the materials sector, rising nickel prices and a series of acquisition bids moved Inco shares to our price target, and we sold the Fund's position in the stock. In the industrials sector, defense company Northrop Grumman advanced on solid order rates and defense spending. We reduced the Fund's posi-tion in the stock as it reached our price target. In telecommunication services, Comcast benefited from its "triple-play" offering of video, high-speed Internet service, and phone service. We sold a portion of the Fund's position as the stock neared our price target. Strong equity and bond markets helped several of the Fund's holdings in the financials sector. Stocks that were sensitive to the capital markets moved sharply higher, including Goldman Sachs, Morgan Stanley, Merrill Lynch, and JPMorgan Chase. We trimmed the Fund's positions in Goldman Sachs and Merrill Lynch as they neared our price targets. Bank of America was also a positive contributor to performance. Among pharmaceutical companies, Pfizer saw its stock price rise on positive product news. Drug retailer CVS also did well, despite a pull-back late in the reporting period. We reduced the Fund's position in CVS as it neared our price target. WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? Information technology holdings were mixed. Nokia and BMC Software advanced, but overall the sector was a negative contributor to the Fund's performance. Two microprocessor manufacturers, Intel and Advanced Micro Devices, both declined on increasing competition. Although Verizon and AT&T advanced, telecommunication services generally detracted from relative results, largely because of weakness at wireless carrier Sprint Nextel. Although the company's acquisition integration was disappointing, we retained a reduced position in the stock because we believed that asset value could serve as a strong catalyst. Another holding that detracted from results was Home Depot, which declined as the housing market slowed. We added to the Fund's position in the stock during the reporting period. HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD? As of October 31, 2006, the Fund held overweighted positions relative to the Russell 1000(R) Value Index in health care, information technology, telecommunication services, and consumer staples. The Fund was under-weighted in consumer discretionary, financials, indus-trials, materials, energy, and utilities. The principal risk of investing in value stocks is that they may never reach what the portfolio manager believes is their full value or they may even go down in value. The Fund may experience a portfolio turnover rate of more than 100% and may generate taxable short-term gains. 1. See footnote on page 6 for more information on the Russell 1000(R) Value 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 Value Fund (the "Fund"), a diversified fund. The Fund currently offers six classes of shares. Distribution of Class A shares commenced on January 3, 1995, Class B shares commenced on May 1, 1986, Class C shares commenced on September 1, 1998 and 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I, Class R1 and Class R2 shares are not subject to a sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are generally withheld at the source. (C) 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 Value Fund treatment; temporary differences do not require reclassification. The following table discloses the current year reclassifications between accumulated undistributed net investment income, accumulated undistributed net realized gain on investments and additional paid-in-capital arising from permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED ACCUMULATED UNDISTRIBUTED NET UNDISTRIBUTED NET REALIZED GAIN ADDITIONAL INVESTMENT INCOME ON INVESTMENTS PAID-IN-CAPITAL $ (79,000) $ (374,000) $ 453,000 - -------------------------------------------------------------- </Table> The reclassifications for the Fund are primarily due to the reimbursement payment (See Note 10 on page 23) and the utilization of earnings and profits on shareholder redemptions. (D) 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 using the effective interest rate method. 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) 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 price of the underlying security or foreign currency increase. 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. 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. When writing a covered call option, the Fund, in return for the premium on the option, gives up the opportunity to profit from a price increase in the underlying securities above the exercise price, but, as long as the obligation as the writer continues, has retained the risk of loss should the price of the underlying security decline. 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. 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 www.mainstayfunds.com 19 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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. (I) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 22.) (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager.

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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and 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 the 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. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total ordinary operating expenses (total annual 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, 1.17% 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $4,546,639 and waived its fees in the amount of $907,175.

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 and Class C shares of the Fund. Class I and Class R1 shares are not subject to a distribution or service fee.

NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. The amount paid to the Fund was $374,000. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 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, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 24 MainStay Value Fund BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's generally mid-range performance over various time periods relative to groupings of funds having similar mandates. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees www.mainstayfunds.com 25 discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoints that would reduce the Fund's management fee at asset levels above the breakpoints, and the fact that the breakpoints were intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund's management fee rate had been reduced by the breakpoint schedule applicable to the Fund. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to maintain a limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. 26 MainStay 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, 2006) as to the federal tax Status of dividends paid by the Fund during such fiscal year. Accordingly, the Fund paid long-term capital gain distributions of $866,376. The dividends paid by the Fund during the fiscal year ended October 31, 2006, should be multiplied by 89.6% to arrive at the amount eligible for qualified dividend income, 5.8% for the qualified interest income and 95.9% for the corporate dividends received deduction.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as 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 4.5% 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. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense. From inception (2/28/97) 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 (2/28/97) through 12/31/03, performance for Class I shares (first offered 1/2/04) includes the historical performance of Class A shares adjusted to reflect the applicable fees and expenses for Class I shares.

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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,038.90 $ 6.68 $1,018.50 $ 6.61 - ---------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,035.25 $10.52 $1,014.75 $10.41 - ---------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,035.25 $10.52 $1,014.75 $10.41 - ---------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,040.90 $ 4.94 $1,020.20 $ 4.89 - ---------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Matthew Philo, CFA, of MacKay Shields LLC HOW DID MAINSTAY DIVERSIFIED INCOME FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay Diversified Income Fund returned 6.67% for Class A shares, 6.01% for Class B shares, and 6.01% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund's Class I shares returned 7.09%. Class I shares outperformed--and Class A, Class B, and Class C shares underperformed--the 6.94% return of the Fund's Three-Index Composite,(1) the Fund's broad-based securities-market index, for the 12-month period. All share classes outperformed the 5.19% return of the Lehman Brothers(R) Aggregate Bond Index over the same period.(2) Class I and Class A shares outperformed--and Class B and Class C shares underperformed--the 6.66% return of the average Lipper(2) multi-sector income fund for the 12 months ended October 31, 2006. WHAT KEY FACTORS DROVE THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? We maintained an overweighted position relative to the benchmark in securitized holdings. We expected solid performance from mortgage-backed and asset-backed securities and were not disappointed. We expected slower price appreciation in the housing market to help residential mortgage-backed securities, since borrowers would have fewer refinancing options and underlying future cash flows would tend to stabilize. Most of our sector views were correct, but the Fund's overweighted Ginnie Mae position detracted from performance when the securities weakened on declining foreign demand. To help manage risk, we decreased the Fund's Ginnie Mae exposure. HOW DID YOU POSITION THE FUND'S PORTFOLIO IN THE CORPORATE BOND MARKET? With corporate-bond spreads caught in various crosscurrents, total returns for corporate-bonds were dominated by coupon income rather than capital gains. Because corporate spreads were relatively tight, we began the reporting period with only modest high-yield exposure and we reduced the Fund's investment-grade corporate exposure to an underweighted position relative to the benchmark. During the reporting period, however, we took advantage of attractive entry points and gradually moved closer to a benchmark-neutral position in high-yield bonds and expanded the Fund's overweighted overall position in investment-grade debt. HOW DID YOU ALLOCATE THE FUND'S HOLDINGS WITHIN THE HIGH-YIELD MARKET? Given the low risk premiums available in the market, we maintained a relatively conservative posture in the high-yield portion of the Fund. With tight spreads, the compensation for taking on additional risk appeared inadequate. As a result, we reduced exposure to lower-quality high-yield bonds and increased exposure to higher-quality high-yield securities. The high-yield portion of the Fund remained underweighted in automotive bonds. GM and Ford became high-yield issuers in 2005, and because both issuers have considerable outstanding debt, their bonds have a major influence on the high-yield market. The Fund maintained its position in GM's finance arm, General Motors Acceptance Corp. Although most of the high-yield portion of the Fund was conservatively positioned, airline holdings were rather volatile, responding directly to changes in oil prices. The Fund maintained its investments in Delta Airlines and Northwest Airlines. Both companies sought to lower their cost structures as they worked through the bankruptcy process. Both positions have benefited from the recent drop in oil prices. HOW DID THE FUND'S EMERGING-MARKET DEBT PERFORM DURING THE REPORTING PERIOD? We continued to add selectively to emerging-market issuers. Since many emerging markets are commodity exporters, the international portion of the Fund's portfolio felt the impact of the run-up in commodity prices. Although energy prices declined toward the end of the reporting period, they remained above 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 more than 100% and may generate taxable short- term capital gains. 1.

See footnote on page 6 for more information on Lipper Inc. www.mainstayfunds.com 9 their historical averages. This allowed emerging-market nations to pursue prudent fiscal management, and we added to the Fund's exposure in emerging- market debt. Emerging-market metals & mining companies traded very cheap relative to their counterparts in developed nations. We added Southern Peru Copper, one of the world's largest copper-mine operators, to the Fund. With copper prices rising, we added to the Fund's exposure in July, and the position is one of the Fund's largest corporate-bond holdings. CVRD is a Brazilian mining company that recently won the takeover battle for Canadian nickel miner Inco. We added exposure to CVRD's 30-year bonds and have been overweighted in the company's 10-year bonds since early in 2006. HOW WAS THE FUND POSITIONED IN THE INTERNATIONAL GOVERNMENT-BOND AND CURRENCY MARKETS? The Fund held an underweighted position in non-dollar investment-grade debt for the entire reporting period. Low nominal yields in countries such as Japan have, in our opinion, made these securities relatively unattractive. Fund assets that would have normally been invested in Japan were reallocated to U.S. convertible bonds. These securities offer higher yields than Japanese government debt and allow the Fund to participate in a domestic equity rally. Outside of Japan, we have been positive on the euro and the British pound and have maintained exposure in these markets for potential currency appreciation. During the reporting period, the euro rose 6% and the British pound gained 10% against the U.S. dollar. WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD? One new area for the Fund has been local-currency emerging-market debt. Although the Fund typically invests in hard-currency debt, usually in U.S. dollars, we felt that the yields on local-currency debt made the bonds attractive, despite currency volatility. Exposure remained relatively low and was well diversified. Results were mixed. The Fund's exposure to Egyptian pounds was surprisingly stable, despite geopolitical tensions in the Middle East. Although Argentina's local-currency bonds rallied along with the nation's dollar-denominated debt, the Argentine peso depreciated more than 4% relative to the U.S. dollar, which eroded some of the Fund's gains on Argentine bonds. DID YOU MAKE ANY SIGNIFICANT WEIGHTING CHANGES DURING THE REPORTING PERIOD? Early in the reporting period, the Fund focused on sectors that offered higher yields or capital-gain potential. During the period, we increased the Fund's exposure to emerging-market debt, high-yield U.S. debt, and convertible bonds. Although the Fund's overall allocation to investment-grade securities increased, we reduced the Fund's exposure in U.S. investment-grade securities, U.S. Treasurys, non-dollar investment-grade government securities, and corporate bonds.

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 commenced on September 1, 1998 and Class I shares commenced 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I shares are not subject to sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The four classes of 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 also 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, as defined in Note 3, 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 trading of the New York Stock Exchange (generally 4:00 p.m. Eastern time). 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 each day the Fund is open for business ("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 ask prices based on dealer or exchange quotations. Temporary cash investments acquired over 60 days prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on the security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund held securities with a value of $234,017 that were valued in such manner. 32 MainStay Diversified Income Fund 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, as defined in Note 3, conclude that such events may have affected 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. Additionally, international equity securities are also fair valued whenever the movement of a particular index exceeds certain amounts. In such cases, the securities are fair valued by applying factors provided by a third party vendor in accordance with the Fund's policies and procedures. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are generally withheld at the source. (C) 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, 2006, are not affected. <Table> <Caption> ACCUMULATED ACCUMULATED DISTRIBUTIONS IN NET REALIZED EXCESS OF NET LOSS ON INVESTMENT INCOME INVESTMENTS $1,238,718 $(1,238,718) - ------------------------------------- </Table> The reclassifications for the Fund are primarily due to premium amortization adjustments, paydown, foreign currency gain (loss) and prior year straddle deferrals. (D) 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 using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, www.mainstayfunds.com 33 NOTES TO FINANCIAL STATEMENTS (CONTINUED) realization and/or retention of the collateral may be subject to legal proceedings. (H) 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 price of the underlying security or foreign currency increase. 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. 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. When writing a covered call option, the Fund, in return for the premium on the option, gives up the opportunity to profit from a price increase in the underlying securities above the exercise price, but, as long as the obligation as the writer continues, has retained the risk of loss should the price of the underlying security decline. 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. 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. (I) 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 the London InterBank Offered Rate ("LIBOR").(See Note 5 on page 37.) The loans in which the Fund invests are generally readily marketable, but may be subject to some restrictions on resale. For example, 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. (J) 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 valuation date to credit loss in the event of a counterparty's failure to perform its obligations. (See Note 6 on page 37.) 34 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) 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, the Fund forgoes principal and interest on the securities. The 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 liquid assets 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. (M) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 on page 37.) (N) 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 Fund does not have the right to demand that such securities be registered. Disposal of these securities may involve time-consuming negotiations and expenses and it may be difficult to obtain a prompt sale at an acceptable price. (See Note 6 on page 37.) (O) 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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and is responsible for the day-to-day portfolio management of the Fund. www.mainstayfunds.com 35 NOTES TO FINANCIAL STATEMENTS (CONTINUED) The Trust, on behalf of the Fund, pays the Manager a monthly fee for the 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. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total ordinary operating expenses (total annual 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, 1.30% 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $701,004 and waived its fees in the amount of $190,789. As of October 31, 2006, the amounts of waived fees that are subject to possible recoupment by the Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $19,479 $190,789 $210,268 - ----------------------------- </Table> * The expense limitation agreement became effective in 2005 and the recoupment will start to expire in 2008. Pursuant to the terms of a Subadvisory Agreement between NYLIM and the Subadvisor, the Manager pays 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 voluntarily agreed to do so proportionately. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (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 and 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 $17,206 for the year ended October 31, 2006. 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 $173, $67,490, and $408, respectively, for the year ended October 31, 2006. (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 pursuant to which it performs certain services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2006, amounted to $354,248. (E) NON-INTERESTED TRUSTEES FEES.

In addition, each Non-Interested Trustee received $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, 2006, New York Life and its affiliates held shares of the Fund with the following values and percentages of net assets as follows: <Table> Class A $8,076,583 12.3% Class B 102 0.0* Class C 106 0.0* Class I 1,106 0.6 - ----------------------------------------------------------------- </Table> * Less than one tenth of one percent. (G) OTHER. Pursuant to an Amended and Restated Management Agreement between the Fund and NYLIM, the cost of legal services provided to the Fund by the Office of the General Counsel of NYLIM are payable directly by the Fund. For the year ended October 31, 2006, these fees, which are included in Professional fees shown on the Statement of Operations, were $3,399. 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 $38,351 for the year ended October 31, 2006. NOTE 4--FEDERAL INCOME TAX: As of October 31, 2006, the components of accumulated gain/(loss) on a tax basis were as follows: <Table> <Caption> ACCUMULATED OTHER TOTAL ORDINARY CAPITAL TEMPORARY UNREALIZED ACCUMULATED INCOME LOSSES DIFFERENCES APPRECIATION LOSS $707,984 $(5,279,384) $(114,780) $2,248,327 $(2,437,853) - ---------------------------------------------------------------- </Table> The difference between book-basis and tax-basis unrealized appreciation is primarily due to wash sale loss deferrals, premium amortization adjustments, straddles, interest on defaulted securities and mark-to-market of foreign currency forward contracts. The other temporary differences is primarily attributable to distribution payable. At October 31, 2006, for federal income tax purposes, capital loss carryforwards of $5,279,384 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) 2008 $1,322 2009 864 2010 1,161 2011 523 2014 1,409 ------------------------------------------- $5,279 ------------------------------------------- </Table> The tax character of distributions paid during the years ended October 31, 2006 and October 31, 2005, shown in the Statement of Changes in Net Assets, were as follows: <Table> <Caption> 2006 2005 Distributions paid from: Ordinary Income $5,818,551 $5,012,863 - --------------------------------------------------------- </Table> NOTE 5--COMMITMENTS AND CONTINGENCIES: At October 31, 2006 the Fund had unfunded loan commitments pursuant to the following loan agreement: <Table> <Caption> UNFUNDED UNREALIZED BORROWER COMMITMENT DEPRECIATION HCA, Inc., due 9/12/07 $ 535,000 $ (2,675) - ------------------------------------------------------ </Table> The commitment is available until the maturity date of the security.

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. These funds paid a commitment fee, at an annual 38 MainStay Diversified Income Fund rate of .070%, up to September 6, 2006 at which time the rate changed to .060% 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.

NOTE 11--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5,882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 12--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and www.mainstayfunds.com 39 NOTES TO FINANCIAL STATEMENTS (CONTINUED) requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 40 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, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 www.mainstayfunds.com 41 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's generally mid-range investment performance over several time periods, its underperformance relative to peers for the trailing one-year period, and its more favorable risk-adjusted returns. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average 42 MainStay Diversified Income Fund shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at asset levels above the breakpoint, and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund had not reached the asset level at which the breakpoint would reduce the Fund's management fee rate. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered that comparative data with respect to other clients of the Manager or Subadvisor was not available as such clients did not have similar investment mandates as the Fund. The Trustees considered the current and proposed contractual and net management fees, its anticipated expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to maintain a limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. www.mainstayfunds.com 43 FEDERAL INCOME TAX INFORMATION (UNAUDITED) The dividends paid by the Fund during the fiscal year ended October 31, 2006, should be multiplied by 1.3% to arrive at the amount eligible for qualified dividend income, 44.7% to arrive at the amount eligible for qualified interest income and 0.5% for the corporate dividends received deduction.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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.

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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,017.60 $ 7.12 $1,018.00 $ 7.12 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,012.55 $10.91 $1,014.25 $10.92 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,014.35 $10.92 $1,014.25 $10.92 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,019.05 $ 3.82 $1,021.25 $ 3.82 - --------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,019.15 $ 4.33 $1,020.75 $ 4.33 - --------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,017.50 $ 5.59 $1,019.50 $ 5.60 - --------------------------------------------------------------------------------------------------------------------------- CLASS R3 SHARES $1,000.00 $1,016.15 $ 6.96 $1,018.15 $ 6.97 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

In the absence of waivers and/or reimbursements, expenses would have been higher. 8 MainStay Large Cap Growth Fund PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (COMPOSITION PIE CHART) <Table> Common Stocks 97.7 Short-Term Investments (collateral from securities lending 5.5 is 5.5%) Liabilities in Excess of Cash and Other Assets (3.2) </Table> See Portfolio of Investments on page 11 for specific holdings within these categories.

Bart Wear, CFA, of Winslow Capital Management, Inc. HOW DID MAINSTAY LARGE CAP GROWTH FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay Large Cap Growth Fund returned 10.04% for Class A shares, 9.13% for Class B shares, and 9.13% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund returned 10.56% for Class I shares, 10.60% for Class R1 shares, 10.25% for Class R2 shares, and 9.66% for Class R3 shares.(1) All share classes underperformed the 10.84% return of the Russell 1000(R) Growth Index,(2) the Fund's broad-based securities-market index, for the 12-month period. On the other hand, all share classes outperformed the 7.42% return of the average Lipper(3) large-cap growth fund for the 12 months ended October 31, 2006. WHICH SECTORS AND INDIVIDUAL STOCKS WERE AMONG THE FUND'S STRONGEST PERFORMERS FOR THE 12 MONTHS ENDED OCTOBER 31, 2006? Telecommunication services, financials, and energy were the three strongest-performing sectors in the Fund during the reporting period. Stock selection and overweighted positions in these sectors relative to the Russell 1000(R) Growth Index helped absolute and relative performance. Telecommunication services results were driven primarily by growth in cell phone service in Latin America. America Movil was a prime beneficiary. Financials advanced on strength among capital markets companies and asset managers. The Fund's position in Goldman Sachs rose significantly. The energy sector's major catalysts were elevated oil prices and robust demand for energy services. Schlumberger was an outstanding Fund holding during the reporting period. Multiline retailer Kohl's advanced on successful management initiatives and comparable-store gains that were above market expectations. WHICH SECTORS AND STOCKS DETRACTED FROM THE FUND'S PERFORMANCE? During the reporting period, the health care sector produced modestly negative returns on an absolute basis, largely because of issues affecting managed care companies and slowing performance among medical-device producers. The Fund's consumer discretionary holdings trailed comparable stocks in the Russell 1000(R) Growth Index, while the Fund's holdings in the information technology sector produced returns essentially in line with related stocks in the benchmark. The Fund's three worst-performing stocks in absolute terms were Yahoo! and eBay in the information technology sector and UnitedHealth Group in the health care sector. Both Yahoo! and eBay struggled with a general slowdown in online business. After years of outstanding performance, UnitedHealth Group saw its share price decline because of questions about its stock-option granting process. WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? We purchased communications semiconductor producer Broadcom for the Fund, but sold the position within a relatively short period after a double-digit gain led us to conclude that the shares were overpriced. We established a position in Nextel International (NII Holdings) to take advantage of strong cell-phone growth in Latin America, and the share price rose significantly. We sold the Fund's position in Golden West Financial at a double-digit gain after Wachovia announced an offer to acquire the company. We eliminated the Fund's position in Harrah's Entertainment after the company an- nounced disappointing earnings. We also sold the Fund's positions in Yahoo! and eBay because of slowing growth. WERE THERE ANY CHANGES IN THE FUND'S POSITION-ING DURING THE REPORTING PERIOD? During the reporting period, we increased the Fund's weighting relative to the Russell 1000(R) Growth Index in the industrials sector to take advantage of strong corporate cash flows and higher capital spending. We reduced the Fund's weighting in the consumer discretionary sector on concerns that higher gasoline prices and higher interest rates might reduce discretionary income. As of October 31, 2006, the Fund had overweighted positions relative to the Russell 1000(R) Growth Index in Goldman Sachs and America Movil. On that same date, the Fund had no underweighted individual stocks relative to the Index. Typically, the subadvisor invests 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. The Fund may experience a portfolio turnover rate of more than 100% and may generate taxable short-term capital gains. 1. Class R3 shares were first offered on April 28, 2006. 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 currently offers seven classes of shares. Distribution of Class A shares, Class B shares, Class C shares, Class I shares, Class R1 shares and Class R2 shares commenced on March 31, 2005. Distribution of Class R3 shares commenced on April 28, 2006. 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 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I, Class R1, Class R2 and Class R3 shares are not subject to sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The seven 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 and Class C shares are subject to higher distribution fee rates than Class A, Class R2 and Class R3 shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I and Class R1 shares are not subject to a distribution or service fee. Class R1, Class R2 and Class R3 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, Class R2 or Class R3 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are generally withheld at the source. (C) 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 20 MainStay Large Cap Growth Fund realized loss on investments and additional paid-in-capital arising from permanent differences; net assets at October 31, 2006, are not affected. <Table> <Caption> NET ACCUMULATED NET ADDITIONAL INVESTMENT REALIZED LOSS PAID-IN LOSS ON INVESTMENTS CAPITAL $2,616,202 $ (4,099) $ (2,612,103) ------------------------------------------- </Table> The reclassification for the Fund is due to the reclassification of net operating losses that cannot be utilized for tax purposes and use of redemptions. (D) 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 using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 24.) (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 which could adversely impact the Fund.

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 written expense limitation agreement if such recoupment does not cause the Fund to exceed the expense limitations.

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 and Class C shares of the Fund. Pursuant to the Class R3 Plan, the Distributor receives a monthly fee from the Fund at the annual rate of 0.50% of the average daily net assets of the Fund's Class R3 shares, which is an expense of the Class R3 shares of the Fund for distribution or service activities as designated by the Distributor.

NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of www.mainstayfunds.com 25 NOTES TO FINANCIAL STATEMENTS (CONTINUED) being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 26 MainStay Large Cap Growth 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 Large Cap Growth Fund (the "Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statements of operations for the year then ended, the statements of changes in net assets and financial highlights for the year then ended, 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 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, 2006, 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, 2006, and the results of its operations for the year ended October 31, 2006, the changes in its net assets and financial highlights for the year ended October 31, 2006, 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 21, 2006 www.mainstayfunds.com 27 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (the "Subadvisor") (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees also considered additional information that they had reviewed during the past year in approving the Subadvisory Agreement in connection with a change of control of the Subadvisor and the solicitation of the Fund's shareholders to approve that Agreement. The Trustees acknowledged the favorable shareholder vote. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees considered the details of the change of control of the Subadvisor and the likely impact that that transaction may have on the long-term management of the Fund. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the reorganization of the Fund with FMI Winslow Growth Fund and another series of the Trust in 2004 and the Fund's continued strong performance under the Subadvisor and its generally favorably risk-adjusted returns since completion of that reorganization. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates and the subadvisory fee payments made by the Manager to the Subadvisor. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Subadvisor, including that the program was designed to reward providing favorable long-term results for clients. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted 28 MainStay Large Cap Growth Fund favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoints that would reduce the Fund's management fee at asset levels above the breakpoints, and the fact that the breakpoints were intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund's management fee rate had been reduced by the breakpoint schedule applicable to the Fund. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager or Subadvisor, including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees reviewed information relating to the amount of the management fee retained by the Manager and the amount paid by the Manager to the Subadvisor. The Trustees generally acknowledged the historical relationships among the Manager and the Trust and the likely difficulties in implementing an alternative to the investment management arrangement between the Manager and the Trust. The Trustees noted the Manager's agreement to waive a certain portion of its management fee, and to maintain a limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. www.mainstayfunds.com 29 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, 2006) as to the federal tax status of dividends paid by the Fund during such fiscal year.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as 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. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense.

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 in 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,019.60 $ 6.82 $1,018.30 $ 6.82 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,015.75 $10.62 $1,014.55 $10.61 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,015.75 $10.62 $1,014.55 $10.61 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,019.45 $ 5.04 $1,020.05 $ 5.04 - --------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,020.65 $ 4.84 $1,020.25 $ 4.84 - --------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,019.05 $ 6.26 $1,018.85 $ 6.26 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Spellman of MacKay Shields LLC HOW DID MAINSTAY MID CAP VALUE FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay Mid Cap Value Fund returned 15.70% for Class A shares, 14.82% for Class B shares, and 14.82% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund's Class I shares returned 16.08%. Class R1 shares returned 16.11% and Class R2 shares returned 15.77%. All share classes underperformed the 20.51% return of the Russell Midcap(R) Value Index,(1) the Fund's broad-based securities-market index, for the 12-month period. All share classes also underperformed the 16.81% return of the average Lipper(2) mid-cap value fund for the 12 months ended October 31, 2006. DURING THE REPORTING PERIOD, WHICH SECTORS WERE STRONG PERFORMERS AND WHICH ONES WERE WEAK? With economies throughout the world posting strong growth, the Fund's industrial holdings experienced solid earnings. These holdings posted the highest absolute returns for the Fund during the 12-month reporting period and made a positive contribution to the Fund's relative performance. The utilities sector also posted strong absolute and relative results for the reporting period, as valuation levels continued to produce record highs for utility stocks in a fairly benign interest-rate environment. The Fund's overweighted position in the energy sector also contributed positively to relative results. Energy stocks benefited from higher crude oil and natural gas prices for much of the reporting period. Although the Fund posted positive absolute returns in the financials, consumer staples, and materials sectors, these sectors were the most significant detractors from the Fund's performance relative to the Russell Midcap(R) Value Index. WHAT WERE SOME OF THE FUND'S BEST-PERFORMING INDIVIDUAL STOCKS DURING THE REPORTING PERIOD? Two offshore drilling companies, Transocean and Global Santa Fe, were the strongest contributors to the Fund's performance. Since crude oil and natural gas prices remained elevated for most of the reporting period, both stocks benefited from the higher rates their drilling fleets were able to command. We sold the Fund's position in Transocean when its shares reached the price target we had previously set. Canadian nickel producer Inco was another strong performer. Inco's shares advanced after the company received multiple takeover bids from other mining companies. We sold the Fund's position in Inco after the stock appreciated to a level above our private market-value estimate. WHICH STOCKS DETRACTED FROM THE FUND'S RESULTS? Shares of specialty chemical company Chemtura hurt the Fund's performance. Chemtura suffered from higher manufacturing input costs and limited ability to pass the expenses along to customers. Lucent Technologies suffered from lackluster business trends, and the company's stock detracted from the Fund's results. After Lucent agreed to merge with French communications company Alcatel, we sold the Fund's position in Lucent Technologies on concerns that the deal would not be a positive development for future share-price performance. The Fund's position in H&R Block also hurt performance, largely because the company's subprime mortgage business posted worse-than-expected results. HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD? Our sale of Transocean and our decision to trim several other energy-related positions as they approached our price targets led to a substantial decrease in the Fund's energy sector overweighting during the reporting period. As of October 31, 2006, the Fund held overweighted positions relative to the Russell Midcap(R) Value Index in industrials, health care, and energy. On the same date, the Fund was underweighted relative to the Index in the utilities, financials, and consumer discretionary sectors. The principal risk of investing in value stocks is that they may never reach what the portfolio manager believes is their full value or they may even go down in value. 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 more than 100% and may generate taxable short-term capital gains. 1.

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 and Class B shares commenced on June 1, 1998, Class C shares commenced on September 1, 1998 and 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I, Class R1 and Class R2 shares are not subject to a sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are generally withheld at the source. (C) 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 Mid Cap Value Fund The following table discloses the current year reclassifications between accumulated undistributed net investment income, accumulated undistributed net realized loss on investment and additional paid-in-capital arising from permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED ACCUMULATED UNDISTRIBUTED NET UNDISTRIBUTED NET ADDITIONAL INVESTMENT REALIZED LOSS ON PAID-IN- INCOME INVESTMENTS CAPITAL $(33,666) $(302,885) $336,551 ------------------------------------------------------- </Table> The reclassifications for the Fund are primarily due to real estate trust distributions. In addition, reclassifications for the Fund are also due to utilization of current and prior years earnings and profits on shareholder redemptions. (D) 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 using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 22.) (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 price of the underlying security or foreign currency increase. 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. 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. When writing a covered call option, the Fund, in www.mainstayfunds.com 19 NOTES TO FINANCIAL STATEMENTS (CONTINUED) return for the premium on the option, gives up the opportunity to profit from a price increase in the underlying securities above the exercise price, but, as long as the obligation as the writer continues, has retained the risk of loss should the price of the underlying security decline. 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. 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. (See Note 5 on page 22.) (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. 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) 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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and 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 the 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. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total ordinary operating expenses (total annual 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, 1.30% 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 written expense limitation 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, 2006, this limit was 1.35% of the average daily net assets of the Class A shares. For the year ended October 31, 2006, the Manager earned fees from the Fund 20 MainStay Mid Cap Value Fund in the amount of $2,672,927, and waived its fees in the amount of $347,680.

Pursuant to the terms of a Subadvisory Agreement between NYLIM and the Subadvisor, 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. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (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 and Class C shares of the Fund. Class I 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 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 $54,675 for the year ended October 31, 2006. 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 $2,290, $255,926 and $5,073, respectively, for the year ended October 31, 2006. (D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.

NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded www.mainstayfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 24 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, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 www.mainstayfunds.com 25 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's underperformance relative to certain measures over several time periods, its more favorable performance over the longest time periods, and a recent portfolio manager change. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher 26 MainStay Mid Cap Value Fund investment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoints that would reduce the Fund's management fee at asset levels above the breakpoints, and the fact that the breakpoints were intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund had not reached the asset level at which breakpoints would reduce the Fund's management fee rate. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to further limit the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. www.mainstayfunds.com 27 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, 2006) as to the federal tax status of dividends paid by the Fund during such fiscal year.

SEC File Number: 811-04550 NYLIM-A09806 (RECYCLE LOGO) MS377-06 MSMV11-12/06 19 (MAINSTAY INVESTMENTS LOGO) MAINSTAY GLOBAL HIGH INCOME FUND Message from the President and Annual Report October 31, 2006 MESSAGE FROM THE PRESIDENT Most stock and bond markets around the world provided positive total returns during the 12 months ended October 31, 2006. International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as 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 4.5% 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. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense. From inception (6/1/98) through 8/31/98, performance of 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,055.90 $ 7.25 $1,018.00 $ 7.12 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,052.65 $11.12 $1,014.25 $10.92 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,052.65 $11.12 $1,014.25 $10.92 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1. Expenses are equal to the Fund's annualized expense ratio of each class (1.40% for Class A, 2.15% for Class B and Class C) multiplied by the average account value over the period, divided by 365 and multiplied by 184 (to reflect the one-half year period). In the absence of waivers and/or reimbursements, expenses would have been higher. www.mainstayfunds.com 7 PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> Governments & Federal Agencies 69.9 Corporate Bonds 22.4 Short-Term Investments (collateral from securities lending 6.5 is 3.0%) Brady Bonds 2.2 Yankee Bond 0.4 Loan Participation 0.0* Liabilities in Excess of Cash and Other Assets (1.4) </Table> * Less than one-tenth of a percent.

Class A shares outperformed--and Class B and Class C shares underperformed--the 11.24% return of the JPMorgan EMBI Global Diversified Index,(1) the Fund's broad-based securities-market index, for the 12-month reporting period. Class A shares outperformed--and Class B and Class C shares underperformed--the 11.68% return of the average Lipper(2) emerging markets debt fund for the 12 months ended October 31, 2006.(3) WHAT ISSUES AFFECTED THE MANAGEMENT OF THE FUND DURING THE REPORTING PERIOD? Despite the challenges of a rising interest-rate environment and the specter of higher global inflation, emerging-market debt registered strong results. As the reporting period progressed, it became apparent that credit improvement in the asset class was not just based on higher commodity prices. The election cycle in Latin America--which is almost always unpredictable--led to price volatility in Peru, Mexico, and Ecuador, where left-leaning candidates took early leads. In Peru and Mexico, candidates who were more market-friendly eventually won. In the end, the Brazilian election was much ado about nothing, since the incumbent easily won a second four-year term. HOW WAS THE FUND POSITIONED IN LATIN AMERICAN MARKETS? Brazilian dollar bonds have been one of our most favored credits. Despite the added volatility caused by Brazil's national elections, Brazilian dollar bonds turned out to be one of the best performers for the Fund. The Fund was significantly overweighted in Brazilian government dollar-denominated debt for most of the reporting period. Other Latin American debt markets also performed well for the Fund. Economic growth outpaced forecasts, and with rare exceptions, national governments maintained prudent fiscal and monetary policies. The best-performing Latin American debt market was Argentina, which emerged from its restructuring last year. Since then, the Argentine economy has grown dramatically. Argentina's government has maintained a relatively firm hold on spending, and early in January 2006, it repaid $9.6 billion to the International Monetary Fund. While there are still structural issues that need to be addressed, we gradually increased exposure to Argentine sovereign debt to 6.0% of the Fund's net assets at the end of October 2006. WHAT EFFECT DID HIGHER COMMODITY PRICES HAVE ON THE FUND'S INVESTMENTS? Since many emerging economies are large commodity exporters, the Fund felt the effects of a run-up in commodity prices during the reporting period. Although energy prices declined toward the end of the reporting period, pricing trends remained above historical averages and supported sovereign governments in the pursuit of prudent fiscal management. We decided to add to the Fund's position in corporate debt during the reporting period. Metals & mining companies in emerging economies were trading at attractive levels compared to their counterparts in developed nations, and we added several names to the Fund in this industry. WHICH CORPORATE BONDS DID YOU ADD TO THE FUND DURING THE REPORTING PERIOD? With copper prices rising, we established a significant position in Southern Peru Copper, one of the world's largest copper-mine operators, in July 2006. Early in 2006, we also added CVRD, a Brazilian 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 more than 100% and may generate taxable short-term capital gains. The Fund is nondiversified. By concentrating in a smaller number of investments, the Fund's risk is increased because each investment has a greater effect on the Fund's performance. 1.

WHAT OTHER CHANGES DID YOU MAKE TO THE FUND DURING THE REPORTING PERIOD? We increased the Fund's exposure to local-currency debt, which produced mixed results. The Fund's exposure to Egyptian pounds was surprisingly stable, despite geopolitical tensions in the Middle East. Although Argentina's local-currency bonds rallied along with the nation's dollar-denominated debt, the Argentine peso depreciated more than 4% relative to the U.S. dollar. The depreciation eroded some of the Fund's gains on Argentine bonds. The opinions expressed are those of the portfolio managers as of the date of this report and are subject to change.

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 and distribution of Class C shares commenced 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The three 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 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, as defined in Note 3, 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 trading of the New York Stock Exchange (generally 4:00 p.m. Eastern time). Temporary cash investments acquired over 60 days prior 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 ask 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund held securities with a value of $1,940,713 that were valued in such manner. Certain events may occur between the time that foreign markets close, on which securities held by the Fund 22 MainStay Global High Income 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, as defined in Note 3, conclude that such events may have affected 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. Additionally, international equity securities are also fair valued whenever the movement of a particular index exceeds certain amounts. In such cases, the securities are fair valued by applying factors provided by a third party vendor in accordance with the Fund's policies and procedures. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are generally withheld at the source. (C) 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, accumulated net realized gain on investments and additional paid-in-capital arising from permanent differences, net assets at October 31, 2006, are not affected. <Table> <Caption> ACCUMULATED ACCUMULATED NET DISTRIBUTIONS IN EXCESS OF REALIZED GAIN ON ADDITIONAL NET INVESTMENT INCOME INVESTMENTS PAID-IN-CAPITAL $99,911 $(110,911) $11,000 - ------------------------------------------------------------------ </Table> The reclassifications for the Fund are primarily due to straddles, paydown, foreign currency gain (loss) and reimbursement payment (See Note 11 on page 29). (D) 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 using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. 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. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. www.mainstayfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) (H) 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 the 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. For example, 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. (I) 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 valuation date to credit loss in the event of a counterparty's failure to perform its obligations. (See Note 5 on page 27.) (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. 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) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 27.) (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 24 MainStay Global High Income Fund 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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and 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 the 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. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total ordinary operating expenses (total annual 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, 1.40% 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $1,357,691, and waived its fees in the amount of $34,288. As of October 31, 2006, the amounts of waived fees that are subject to possible recoupment by the Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $38,120 $34,288 $72,408 - ------------------------- </Table> * The expense limitation agreement became effective 2005 and the recoupments will start to expire in 2008. Pursuant to the terms of a Subadvisory Agreement between NYLIM and the Subadvisor, 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. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (B) PAYMENTS FROM AFFILIATES. NYLIM reimbursed or paid all expenses relating to the Board of Trustees' review of certain shareholder trading matters as described below in the footnote relating to "Other Matters." (See Note 11 on page 29.) The total costs associated with the Board of Trustees' review were approximately $849,975 and included payments to certain third party service providers. The amount that was reimbursed to the Fund was $23,939. Additional payments were made by affiliates relating to the shareholder trading matters. Further discussion regarding these payments by affiliates can be found below in the footnote relating to "Other Matters." (C) 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 www.mainstayfunds.com 25 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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 and 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. (D) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $75,700 for the year ended October 31, 2006. 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 $6,593, $79,068 and $8,025, respectively, for the year ended October 31, 2006. (E) 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.

The Audit and Compliance Committee Chairman received 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 received an additional $1,000 for each meeting of the respective committee meetings attended. In addition, each Non-Interested Trustee received $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. (G) CAPITAL. At October 31, 2006, New York Life and its affiliates held shares of the Fund with the following values and percentages of net assets as follows: <Table> Class A $7,683,570 6.3% - ------------------------------------------------------------------- Class C 314 0.0* - ------------------------------------------------------------------- </Table> * Less than one tenth of one percent.

All such arrangements were terminated by the fourth quarter of 2003. NYLIM and the Trustees of the Trust undertook a review of 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 $5.882 million to nine MainStay funds. The amount paid to the Fund was $11,000. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 12--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. www.mainstayfunds.com 29 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, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 30 MainStay Global High Income Fund BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's mid-range investment performance over certain time periods, and its more favorable performance over the medium term. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average www.mainstayfunds.com 31 shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at asset levels above the breakpoint and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund had not reached the asset level at which the breakpoint would reduce the Fund's management fee rate. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to maintain a limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. 32 MainStay Global High Income Fund FEDERAL INCOME TAX INFORMATION (UNAUDITED) The dividends paid by the Fund during the fiscal year ended October 31, 2005, should be multiplied by 4.4% to arrive at the amount eligible for qualified interest income.

SEC File Number: 811-04550 NYLIM-A09806 [RECYCLE LOGO] MS377-06 MSGH11-12/06 20 (MAINSTAY INVESTMENTS LOGO) MAINSTAY COMMON STOCK FUND Message from the President and Annual Report October 31, 2006 MESSAGE FROM THE PRESIDENT Most stock and bond markets around the world provided positive total returns during the 12 months ended October 31, 2006. International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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 ON VALUE (BASED HYPOTHETICAL BEGINNING ON ACTUAL EXPENSES 5% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,062.80 $ 6.76 $1,018.50 $ 6.61 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,059.05 $10.64 $1,014.75 $10.41 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,059.05 $10.64 $1,014.75 $10.41 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,066.10 $ 3.44 $1,021.70 $ 3.36 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

In the absence of waivers and/or reimbursements, expenses would have been higher. www.mainstayfunds.com 7 PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> Common Stocks 98.2 Short-Term Investments (collateral from securities lending 11.6 is 11.6%) Investment Companies 2.0 Liabilities in Excess of Cash and Other Assets (11.8) </Table> See Portfolio of Investments on page 10 for specific holdings within these categories.

Excluding all sales charges, MainStay Common Stock Fund returned 16.43% for Class A shares, 15.58% for Class B shares, and 15.49% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund's Class I shares returned 17.19%. Class A and Class I shares outperformed--and Class B and Class C shares underperformed--the 16.34% return of the S&P 500(R) Index,(1) the Fund's broad-based securities-market index, for the 12-month period. All share classes outperformed the 14.23% return of the average Lipper(2) large-cap core fund for the 12 months ended October 31, 2006. DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST POSITIVE CONTRIBUTIONS TO THE FUND'S PERFORMANCE AND WHICH ONES WERE THE WEAKEST? The sectors that made the greatest positive contributions the Fund's performance relative to the S&P 500(R) Index were information technology, energy, and telecommunication services. Within each of these sectors, the greatest impact on relative return came from security selection. The information technology sector was led by communications equipment and Internet software companies, while strong oil prices helped the energy sector advance. Financials, industrials, and utilities were the Fund's weakest-performing sectors relative to the S&P 500(R) Index, especially as interest rates trended higher during most of the reporting period. WHICH INDIVIDUAL STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? The strongest individual contributors to the Fund's absolute performance during the reporting period were petroleum giant ExxonMobil, telecommunications leader BellSouth, and pharmaceuticals manufacturer Merck & Company. It should be noted, however, that the Fund holds approximately 450 to 500 securities and weightings are typically within 75 basis points of the corresponding position in the benchmark. As a result, no single stock will have a significant positive or negative impact on the Fund's performance relative to the Index. WHICH INDIVIDUAL STOCKS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD? Major detractors from the Fund's absolute performance during the reporting period were computer manufacturer Dell, semiconductor giant Intel, and health care services provider UnitedHealth Group. WHAT WERE SOME OF THE PURCHASES OR SALES MADE DURING THE REPORTING PERIOD? The Fund seeks stocks with attractive valuations, reliable earnings, and strong price trends. Among the stocks purchased by the Fund during the reporting period were UTStarcom and Big Lots. Securities that were sold included Precision Castparts and Honeywell International. WERE THERE ANY CHANGES IN THE FUND'S SECTOR POSITIONING DURING THE REPORTING PERIOD? Weighting changes in the Fund result from a combination of security performance and the Fund's proprietary quantitative security-selection process. During the reporting period, the Fund's weightings in the consumer discretionary and financials sectors increased. The Fund's weightings in the utilities and consumer staples sectors decreased. As of October 31, 2006, the Fund was overweighted relative to the S&P 500(R) Index in the financials and consumer discretionary sectors. The Fund was underweighted in the consumer staples and industrials sectors. The principal risk of growth stocks is that investors expect growth companies to increase their earnings at a certain rate that is generally higher than the rate expected for nongrowth companies. If these expectations are not met, the market price of the stock may decline significantly, even if earnings showed an absolute increase. The Fund may experience a portfolio turnover rate of more than 100% and may generate taxable short-term capital gains. 1. See footnote on page 6 for more information on the S&P 500(R) 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 Common Stock Fund (the "Fund"), a diversified fund. The Fund currently offers four classes of shares. Class A shares and Class B shares commenced on June 1, 1998. Class C shares commenced on September 1, 1998. 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I shares are not subject to sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The four classes of 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006 the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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 undistributed net investment income, accumulated net realized gain on investments and 22 MainStay Common Stock Fund additional paid-in-capital arising from permanent differences; net assets at October 31, 2006, are not affected. <Table> <Caption> ACCUMULATED UNDISTRIBUTED ACCUMULATED NET ADDITIONAL NET INVESTMENT REALIZED GAIN ON PAID-IN- INCOME INVESTMENTS CAPITAL $(44,515) $8,539 $35,976 -------------------------------------------- </Table> The reclassifications for the Fund are primarily due to real estate trust distributions. In addition, reclassifications for the Fund are also due to utilization of earnings and profits on shareholder redemptions. (D) 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 using the effective interest rate method. 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 25.) (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment advisor and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 the services performed and the facilities furnished at an annual percentage of the Fund's average www.mainstayfunds.com 23 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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, 2006, NYLIM has contractually agreed to waive a portion of its management fee so that the management fee is 0.60% on assets up to $500 million and 0.55% on assets in excess of $500 million. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total operating expenses (total annual 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, 1.30% 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $1,401,016, and waived its fees in the amount of $606,802. As of October 31, 2006 the amounts of waived fees that are subject to possible recoupment by the Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $124,534 $606,802 $731,336 ------------------------------------------ </Table> * The expense limitation agreement became effective in 2005 and the recoupments will start to expire in 2008. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts, 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (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 and 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 $11,467 for the year ended October 31, 2006. 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 $865, $47,450 and $464, respectively, for the year ended October 31, 2006 . (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 pursuant to which it performs certain services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund for the year ended October 31, 2006, amounted to $509,116. (E) NON-INTERESTED TRUSTEES FEES. For the year ended October 31, 2006, Non-Interested Trustees were paid an annual retainer of $45,000, $2,000 for each Board meeting attended, $1,000 for each Committee meeting attended and $500 for each Valuation Subcommittee telephonic meeting attended plus reimbursement for travel and out-of-pocket expenses. The Lead Non-Interested Trustee received an additional annual retainer of $20,000. The Audit and Compliance Committee Chairman received 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 received an additional $1,000 for each meeting of the respective committee meetings attended.

NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 26 MainStay Common Stock 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 Common Stock Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 www.mainstayfunds.com 27 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager (the "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of the Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of the Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under the Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services and administrative services. The investment management services include, but are not limited to, monitoring and evaluating the Fund's investment program and investment results, providing the day-to-day portfolio management of the Fund, determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets, and the Fund's compliance with its investment policies and restrictions. The administrative services include, but are not limited to, working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Trustees also considered the Manager's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Manager's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust and certain other service providers. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously 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 Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's recent above average investment performance, the Fund's mid-range longer term performance, measures that the Manager had recently taken in seeking to improve the Fund's performance by increasing the Fund's tracking error with respect to its benchmark, a recent change of portfolio management personnel, and the recent success of the portfolio management team in attracting investments from certain institutional investors in other products managed by the team. 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 reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreement, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. 28 MainStay Common Stock Fund The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at levels above the breakpoint and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund had not reached the asset level at which the breakpoint would reduce the Fund's management fee rate. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager, including registered and other funds as well as separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationship between the Manager and the Trust. The Trustees took account of the Manager's willingness and agreement to reduce the Fund's contractual fee, while noting that the expense limitation applicable to the Fund remained unchanged. 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering 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 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 the Agreement 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 January 2007, shareholders will receive on IRS Form 1099-DIV or substitute Form 1099 the federal tax status of the distributions received by shareholders in calendar year 2006.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. Sincerely, /s/ CHRISTOPHER O. BLUNT Christopher O.

Performance figures reflect certain fee waivers and/or expense limitations, without which total returns may have been lower. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense. 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 5/30/06, performance of Class I shares (first offered 5/31/06) 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. 1. Performance figures shown for the year ended October 31, 2006 reflect nonrecurring reimbursements from affiliates for professional fees and losses attributable to shareholder trading arrangements. (See Note 3(B) on page 22 of the Notes to Financial Statements for further explanation). The effect on total return (excluding sales charges) was less than 0.01%. 2. The Russell 2000(R) Growth Index is an unmanaged index that measures the performance of those Russell 2000(R) companies with higher price-to-book ratios and higher forecasted growth values. Results assume the reinvestment of all income and capital gains. The Russell 2000(R) Growth Index is considered to be the Fund's broad-based securities-market index for comparison purposes. An investment cannot be made directly in an index. 3. The Russell 2000(R) Index is an unmanaged index that measures the performance of the 2,000 smallest companies in the Russell 3000(R) Index, which, in turn, is an unmanaged index that measures the performance of a the 3,000 largest U.S. companies based on total market capitalization. Results assume the reinvestment of all income and capital gains. An investment cannot be made directly in an index. 4. Lipper Inc. is an independent fund performance monitor. Results are based on total returns with all dividend and capital-gain distributions reinvested.

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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $937.50 $ 7.23 $1,017.60 $ 7.53 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $933.95 $10.87 $1,013.85 $11.32 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $933.95 $10.87 $1,013.85 $11.32 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $940.75 $ 3.15(2) $1,021.15 $ 3.28(2) - --------------------------------------------------------------------------------------------------------------------------- </Table> 1. Expenses are equal to the Fund's annualized expense ratio of each class (1.48% for Class A, 2.23% for Class B and Class C, and 0.77% for Class I) multiplied by the average account value over the period, divided by 365 and multiplied by 184 for all share classes except Class I (to reflect the one-half year period) and multiplied by 154 for Class I (to reflect the since inception period). In the absence of waivers and/or reimbursements, expenses would have been higher. 2. Shares were first offered on May 31, 2006. Expenses paid during the period reflect ongoing costs for the since-inception period ending October 31, 2006. Had these shares been offered for the six months ended October 31, 2006, based on a hypothetical 5% annualized return, expenses paid during the period would be $3.92, and the ending account value would be $1,021.15. www.mainstayfunds.com 7 PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> Common Stocks 95.5 Short-Term Investments (collateral from securities lending is 19.0%) 23.8 Liabilities in Excess of Cash and Other Assets (19.3) </Table> See Portfolio of Investments on page 11 for specific holdings within these categories.

Spelman of MacKay Shields LLC HOW DID MAINSTAY SMALL CAP GROWTH FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? Excluding all sales charges, MainStay Small Cap Growth Fund returned 10.11% for Class A shares, 9.28% for Class B shares, and 9.28% for Class C shares for the 12 months ended October 31, 2006. Over the same period, Class I shares returned 10.60%.(1) All share classes underperformed the 17.07% return of the Russell 2000(R) Growth Index,(2) the Fund's broad-based securities-market index, for the 12-month period. All share classes also underperformed the 12.82% return of the average Lipper(3) small-cap growth fund for the 12 months ended October 31, 2006.(4) WHAT SECTORS HAD THE GREATEST IMPACT ON THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING PERIOD? Favorable stock selection in the information technology sector helped the Fund's performance during the 12 months ended October 31, 2006. An overweighted position in the industrials sector and an underweighted position in health care also helped the Fund's relative results. On the other hand, the Fund's stock selection in the health care, energy, and consumer discretionary sectors detracted from the Fund's relative performance. An overweighted position in consumer discretionary stocks and an underweighted position in the materials sector also hurt the Fund's relative results. WHAT WERE SOME OF THE FUND'S STOCK-SPECIFIC SUCCESS STORIES AND WHICH STOCKS LOST GROUND? Top performers included Terex, a manufacturer of cranes and other heavy equipment; Tetra Technologies, an oil services company operating in the Gulf of Mexico; Children's Place, a child-oriented retailer; and Coldwater Creek, a retailer with catalogue and mail order operations and a growing chain of stores. Another strong performer was Diodes, which gained share in the discrete semiconductor business. Disappointing stocks included James River Coal and Massey Energy, which saw lagging earnings. ASV, a supplier to the construction-equipment market, declined on slowing end-market demand. SFBC International was hurt by slowing new business trends and serious missteps in corporate governance that led to a government investigation. Shares of Labor Ready, a temporary employment company for the construction industry, lagged on slowing demand. We sold the Fund's positions in James River Coal, Massey Energy, and SFBC International during the reporting period. WHICH OTHER STOCKS DID THE FUND SELL DURING THE REPORTING PERIOD? As the housing market cooled, we eliminated several homebuilders, including Hovnanian Enterprises, MDC Holdings, The Ryland Group, and WCI Communities. Deteriorating fundamentals led us to sell several energy holdings, including Alliance Resource Partners, Arch Coal, and Bronco Drilling. Finally, we sold the Fund's positions in Hughes Supply, Petco, Remington Oil & Gas, and Westcorp because of merger activity. WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD? We added a position in Phillips Van Heusen to benefit from the company's core men's shirt business and expanding Calvin Klein licensing operations. We also added RBC Bearings, which makes bearing components for the aerospace, defense, and industrial markets. We established a Fund position in Cash America, a provider of specialty financial services, including pawn shop lending and cash advances on paychecks. In the information technology sector, we added WebEx Communications, a provider of Internet-based conferencing services, and Cymer, a manufacturer of specialized light-source systems used in semiconductor manufacturing. The principal risk of growth stocks is that investors expect growth companies to increase their earnings at a certain rate that is generally higher than the rate expected for nongrowth companies. If these expectations are not met, the market price of the stock may decline significantly, even if earnings showed an absolute increase. 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. The Fund may experience a portfolio turnover rate of more than 100% and may generate taxable short-term capital gains. 1. Class I shares were first offered May 31, 2006. 2. See footnote on page 6 for more information on the Russell 2000(R) Growth Index. 3. See footnote on page 6 for more information about Lipper Inc. 4. Performance figures for the year ended October 31, 2006, reflect nonrecurring reimbursements from affiliates. Without these reimbursements, total returns would have been lower. See Note 1 on page 6. www.mainstayfunds.com 9 DID THE FUND CHANGE ITS SECTOR WEIGHTINGS DURING THE REPORTING PERIOD? During the 12 months ended October 31, 2006, we increased the Fund's weighting in information technology. We decreased the Fund's weightings in the consumer discretionary and energy sectors, which had a positive effect on performance. We also eliminated exposure to the materials sector. As of October 31, 2006, the Fund held overweighted positions relative to the Russell 2000(R) Growth Index in energy, industrials, and financials. On the same date, the Fund held underweighted positions in the consumer discretionary, consumer staples, health care, and information technology sectors. At the end of the reporting period, the Fund had no holdings in materials, telecommunication 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 Small Cap Growth 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 and Class I shares commenced on May 31, 2006. 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I shares are not subject to sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The four classes of 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 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006 the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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, accumulated net realized loss on investments and additional paid- 20 MainStay Small Cap Growth Fund in-capital arising from permanent differences; net assets at October 31, 2006, are not affected. <Table> <Caption> ACCUMULATED NET ACCUMULATED NET REALIZED LOSS ON ADDITIONAL INVESTMENT LOSS INVESTMENTS PAID-IN-CAPITAL $3,630,821 $(38,000) $(3,592,821) ---------------------------------------------------- </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 miscellaneous adjustments. (D) 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 using the effective interest rate method. 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 23.) (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and is responsible for the day-to-day portfolio management of the Fund. www.mainstayfunds.com 21 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: 1.00% on assets up to $1.0 billion and 0.95% on assets in excess of $1.0 billion. NYLIM has voluntarily agreed to waive its management fee by 0.15% to 0.85% on assets up to $1.0 billion, and to 0.80% on assets in excess of $1.0 billion. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total operating expenses (total annual 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, 1.48% 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 written expense limitation 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. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $2,406,116 and waived its fees in the amount of $1,066,861. As of October 31, 2006, the amounts of waived fees that are subject to possible recoupment by the Manager, and the related expiration dates are as follows: <Table> <Caption> OCTOBER 31, 2008* 2009 TOTAL $174,275 $705,943 $ 880,218 ------------------------------- </Table> * The expense limitation agreement became effective in 2005 and the recoupments will start to expire in 2008. Pursuant to the terms of a Subadvisory Agreement between NYLIM and the Subadvisor, 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 manager has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so proportionately. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (B) PAYMENTS FROM AFFILIATES. NYLIM reimbursed or paid all expenses relating to the Board of Trustees' review of certain shareholder trading matters as described below in the footnote relating to "Other Matters." (See Note 10 on page 24.) The total costs associated with the Board of Trustees' review were approximately $849,975 and included payments to certain third party service providers. The amount that was reimbursed to the Fund was $32,348. Additional payments were made by affiliates relating to the shareholder trading matters. Further discussion regarding these payments by affiliates can be found below in the footnote relating to "Other Matters." (C) 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 and 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. (D) SALES CHARGES. The Fund was advised by the Distributor that the amount of sales charges retained on sales of Class A shares was $39,460 for the year ended October 31, 2006. 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 $2,388, $174,032 and $1,580, respectively, for the year ended October 31, 2006.

NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. The amount paid to the Fund was $38,000. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 24 MainStay Small Cap Growth 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 Growth Fund (the "Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 www.mainstayfunds.com 25 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's underperformance when compared over several time periods with groupings of funds having similar investment mandates, and the Manager's assurance that it was closely monitoring the Fund's performance. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher invest- 26 MainStay Small Cap Growth Fund ment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at asset levels above the breakpoint and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund had not reached the asset level at which the breakpoint would reduce the Fund's management fee rate. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered certain comparative data with respect to other clients of the Manager and Subadvisor, including other registered funds and separate institutional accounts having investment strategies similar to that of the Fund, and took account of explanations and other information relating to the fees and expenses of those other funds and accounts. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to waive a certain portion of its management fee, and to maintain a limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. www.mainstayfunds.com 27 PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD A description of the policies and procedures that NYLIM uses to vote proxies related to the Fund's securities is available without charge, upon request, (i) by visiting the Fund's website at www.mainstayfunds.com; or (ii) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. 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 as 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. These fee waivers and/or expense limitations are contractual and may be modified or terminated only with the approval of the Board of Trustees. The Manager may recoup the amount of any management fee waivers or expense reimbursements from the Fund pursuant to this agreement if such action does not cause the Fund to exceed existing expense limitations and the recoupment is made within three years after the year in which the Manager incurred the expense.

The Russell 2000(R) Value Index is an unmanaged index that measures the performance of those Russell 2000(R) companies with lower price-to-book ratios and lower forecasted growth values. The Russell 2000(R) Index is an unmanaged index that measures the performance of the 2,000 smallest companies in the Russell 3000(R) Index which, in turn, is an unmanaged index that measures the performance of the 3,000 largest U.S. companies based on total market capitalization. Results assume reinvestment of all income and capital gains. The Russell 2000(R) Value Index is considered to be the Fund's broad-based securities-market index for comparison purposes. An investment cannot be made directly in 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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $977.30 $ 6.98 $1,018.00 $ 7.12 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $973.15 $10.69 $1,014.25 $10.92 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $973.85 $10.70 $1,014.25 $10.92 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $977.15 $ 5.23 $1,019.75 $ 5.35 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

In the absence of waivers and/or reimbursements, expenses would have been higher. www.mainstayfunds.com 7 PORTFOLIO COMPOSITION AS OF OCTOBER 31, 2006 (PORTFOLIO COMPOSITION PIE CHART) <Table> Common Stocks 91.6 Short-Term Investments (collateral from securities lending 25.0 is 16.4%) Investment Companies 3.0 Liabilities in Excess of Cash and Other Assets (19.6) </Table> * Includes 0.8% of Investment Companies Securities.

Excluding all sales charges, MainStay Small Cap Value Fund returned 13.40% for Class A shares, 12.48% for Class B shares, and 12.56% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund's Class I shares returned 13.74%. All share classes underperformed the 22.90% return of the Russell 2000(R) Value Index,(1) the Fund's broad-based securities-market index, for the 12-month period. All share classes also underperformed the 16.79% return of the average Lipper(2) small-cap value fund for the 12 months ended October 31, 2006. DURING THE REPORTING PERIOD, WHICH SECTORS WERE THE FUND'S STRONGEST PERFORMERS AND WHICH SECTORS WERE THE WEAKEST? For the 12 months ended October 31, 2006, the Fund's strongest-performing sectors relative to the Russell 2000(R) Value Index were energy and information technology. On a relative basis, the weakest-performing sectors were consumer discretionary, financials, and industrials. In the consumer discretionary sector, the Fund's contrarian investments in such media-related industries as publishing and broadcasting & cable hurt both absolute and relative returns. During the reporting period, these media-related industries suffered from declines in advertising spending because of growth in new advertising media, mainly the Internet. In the financials sector, specific Fund holdings in reinsurance and multi-line insurance companies hurt returns. WHICH STOCKS WERE THE FUND'S STRONGEST PERFORMERS AND WHICH STOCKS UNDERPERFORMED DURING THE REPORTING PERIOD? The strongest contributors to the Fund's absolute performance included retailer Christopher & Banks, chemical-transportation company Quality Distribution, and software company Mentor Graphics. Major detractors from the Fund's absolute performance included reinsurance company Scottish Re Group, newspaper publisher Journal Register, and engineering and gas-turbine equipment provider Global Power Equipment. WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? The Fund initiated a new position in Horizon Offshore, a marine construction company operating primarily in the Gulf of Mexico during the reporting period. We also purchased shares of Brooks Automation, a designer and manufacturer of equipment sold primarily into the semiconductor end-market. The Fund made two significant sales in July 2006. We eliminated the Fund's position in Scottish Re Group when the company unexpectedly reported large write-offs that led to the CEO's resignation. We also sold the Fund's position in Global Power Equipment when the company faced a contract-accounting review that delayed timely filing of SEC documents. The Fund eliminated its position in the stock before Global Power Equipment filed for Chapter 11 bankruptcy protection. DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD? The Fund's sector weightings are primarily a result of our bottom-up security-selection process, which focuses on attractive valuations. Industry and security movements may also affect weightings. During the 12-month reporting period, the Fund's exposure to the materials and telecommunication services sectors increased relative to the Russell 2000(R) Value Index. On the other hand, the Fund decreased its exposure to the information technology, consumer discretionary, and energy sectors. At the end of October 2006, the Fund's only significantly overweighted sector relative to the Russell 2000(R) Value Index was consumer discretionary, where our stock selection detracted from the Fund's relative performance. The Fund had a significantly underweighted position in financials, which helped relative results. 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. The principal risk of investing in value stocks is that they may never reach what the portfolio manager believes is their full value or they may even go down in value. 1.

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 commenced on September 1, 1998 and 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I shares are not subject to sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The four classes of 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 each day the Fund is open for business ("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 prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund did not hold securities that were valued in such manner. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. (C) 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 distributions in excess of the net investment and accumulated net realized loss on 18 MainStay Small Cap Value Fund investments arising from permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED NET INVESTMENT NET REALIZED GAIN ADDITIONAL LOSS ON INVESTMENTS PAID-IN-CAPITAL $121,960 $6,391 $(128,351) ---------------------------------------------------- </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. (D) 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 using the effective interest rate method. 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (H) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 21.) (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 adviser and an indirect wholly-owned subsidiary of New York Life, serves as subadvisor to the Fund and 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 the 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. NYLIM has voluntarily agreed to waive its management fee by 0.25% to 0.60% on assets up to $1.0 billion, and 0.55% on assets in excess of $1.0 billion. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total ordinary operating expenses (total annual 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, 1.55% 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 written expense limitation 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, 2006, this limit was 1.90% of the average daily net assets of the Class A shares. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $1,198,218, and waived its fees in the amount of $352,417. As of October 31, 2006, there is no amount of waived fees that are subject to possible recoupment by the Manager. Pursuant to the terms of a Subadvisory Agreement between NYLIM and the Subadvisor, 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. Investors Bank & Trust Company, 200 Clarendon Street, P.O. Box 9130, Boston, Massachusetts 02116 ("IBT") provides sub-administration and sub-accounting services to the Fund pursuant to an agreement with NYLIM. These services include calculating daily net asset values of the Fund, maintaining general ledger and sub-ledger accounts for the calculation of the Fund's respective net asset values, and assisting NYLIM in conducting various aspects of the Fund's administrative operations. For providing these services to the Fund, IBT is compensated by NYLIM. (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 and 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 $20,645 for the year ended October 31, 2006. 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 $793, $63,861 and $5,229, respectively, for the year ended October 31, 2006. (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 pursuant to which it performs certain services for which NYLIM Service is responsible. Transfer agent expenses incurred by the Fund, for the year ended October 31, 2006, amounted to $463,896. (E) NON-INTERESTED TRUSTEES FEES.

NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 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, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 www.mainstayfunds.com 23 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreement between the Manager and the Subadvisor (each an "Agreement") at a meeting held on June 12 and 13, 2006. In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and the Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors 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 the Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating the Subadvisor's investment program and investment results with respect to the Fund and the Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. The Subadvisor is responsible for the day-to-day portfolio management of the Fund, including determining the composition of assets of the Fund and the timing of the Fund's execution of the purchase and sale of assets. In addition, the Subadvisor provides reports to the Manager and reviews certain aspects of Fund filings. The Trustees also considered the Manager's and Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed reports on the Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, the Subadvisor and certain other service providers, and the Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and the Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and the Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board's decision took account of, among other things, the Fund's underperformance over several time periods relative to groupings of funds having similar mandates, and the Manager's assurance that it was closely monitoring the Fund's performance. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees reviewed information about the compensation program for portfolio managers employed by the Manager, including that the program was designed to align portfolio manager compensation with investors' goals. The Trustees also reviewed information about portfolio manager holdings in the Trust and generally noted favorably those portfolio managers of the Trust who invest in portfolios they manage. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees 24 MainStay Small Cap Value Fund discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at asset levels above the breakpoint and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund had not reached the asset level at which the breakpoint would reduce the Fund's management fee rate. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. The Trustees considered that comparative data with respect to other clients of the Manager or Subadvisor was not available as such clients did not have similar investment mandates as the Fund. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, the Subadvisor and the Trust. The Trustees noted the Manager's agreement to waive a certain portion of its management fee, and the Manager's willingness to further lower the limit on the Fund's net expenses to a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement was in the best interests of the Fund and its shareholders. www.mainstayfunds.com 25 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, 2006) as to the federal tax status of dividends paid by the Fund during such fiscal year.

SEC File Number: 811-04550 NYLIM-A09806 (RECYCLE LOGO) MS377-06 MSSV11-12/06 25 (MAINSTAY INVESTMENTS LOGO) MAINSTAY MAP FUND Message from the President and Annual Report October 31, 2006 MESSAGE FROM THE PRESIDENT Most stock and bond markets around the world provided positive total returns during the 12 months ended October 31, 2006. International stocks were exceedingly strong, with all industry sectors providing positive returns. Of course, past performance is no guarantee of future results. On average, U.S. stocks at all capitalization levels provided double-digit total returns. According to Russell data, value stocks outperformed growth stocks for companies of all sizes. Strong growth in corporate profits contributed to the stock market's advance, and positive earnings surprises continued to outnumber negative ones. The price of oil and other commodities rose during the reporting period but softened somewhat toward the end. This helped alleviate inflation concerns, as did a noticeable softening in the housing market. In February 2006, Dr. Ben Bernanke replaced Dr. Alan Greenspan as Chairman of the Federal Reserve Board. Although the Federal Open Market Committee continued to raise the targeted federal funds rate during the reporting period, the monetary-tightening policy that began on June 30, 2004, finally abated after the federal funds target reached 5.25% on June 29, 2006. The effects of Federal Reserve tightening were not felt uniformly across the Treasury yield curve. Although short-term rates rose substantially during the reporting period, longer-term rates moved relatively little. At various times the yield curve inverted, and toward the end of the reporting period, the yield curve remained relatively flat. The shape of the yield curve was influenced by the reintroduction of the 30-year bond, projections of a cooler economy, Federal Reserve efforts to keep inflation in check, and an increase in buying by hedge funds, foreign banks, and other liquidity buyers. Most bond sectors provided positive total returns. High-yield corporate bonds and emerging-market debt were particularly strong. We are pleased to inform our shareholders that on June 30, 2006, New York Life Investment Management LLC closed a definitive merger agreement with Institutional Capital Corporation (ICAP), a premier value-equity institutional investment firm based in Chicago, Illinois. In July 2006, ICAP also began serving as comanager of MainStay MAP Fund. In the fall of 2006, we added three new Funds managed by ICAP--MainStay ICAP International Fund, MainStay ICAP Select Equity Fund, and MainStay ICAP Equity Fund. Each MainStay Fund is managed using a time-tested investment approach that includes investment strategies and processes appropriate to the Fund's investment objective. The Funds' portfolio managers seek to consistently apply this investment approach even when markets shift or company fundamentals change. In this way, the portfolio managers seek to avoid style drift and unnecessary risk exposure as they pursue long-term performance for the assets under their care. The following report provides more detailed information about the market factors and management decisions that influenced your MainStay investment during the 12 months ended October 31, 2006. We thank you for entrusting your assets to MainStay, and we hope that you will be encouraged by the positive performance of your Fund. Sincerely, /s/ CHRISTOPHER O. BLUNT Christopher O.

Going forward, the Fund will measure its performance against the Russell 3000(R) Index. The Fund selected the Russell 3000(R) Index because it believes that this index is more reflective of the Fund's investment style. The Russell 3000(R) Index measures the performance of the 3,000 largest U.S. companies based on total market capitalization. Results assume reinvestment of all income and capital gains. An investment cannot be made directly in an index. 2. 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) Index is considered to be the Fund's broad-based securities-market index for comparison purposes. An investment cannot be made directly in an index. 3. "S&P 500(R)" is a trademark of The McGraw-Hill Companies, Inc. The S&P 500(R) is an unmanaged index and is widely regarded as the standard for measuring large-cap U.S. stock-market performance. Results assume reinvestment of all income and capital gains. An investment cannot be made directly in an index. 4. Lipper Inc. is an independent fund performance monitor. Results are based on total returns with all dividend and capital-gain distributions reinvested.

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, 2006, to October 31, 2006. 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, 2006. 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 with the ongoing costs of investing in 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% ANNUALIZED EXPENSES ACCOUNT RETURNS AND PAID RETURN AND PAID VALUE EXPENSES) DURING ACTUAL EXPENSES) DURING SHARE CLASS 5/1/06 10/31/06 PERIOD(1) 10/31/06 PERIOD(1) CLASS A SHARES $1,000.00 $1,029.55 $ 6.91 $1,018.25 $ 6.87 - --------------------------------------------------------------------------------------------------------------------------- CLASS B SHARES $1,000.00 $1,025.90 $10.72 $1,014.50 $10.66 - --------------------------------------------------------------------------------------------------------------------------- CLASS C SHARES $1,000.00 $1,025.90 $10.72 $1,014.50 $10.66 - --------------------------------------------------------------------------------------------------------------------------- CLASS I SHARES $1,000.00 $1,030.55 $ 5.27 $1,019.85 $ 5.24 - --------------------------------------------------------------------------------------------------------------------------- CLASS R1 SHARES $1,000.00 $1,030.05 $ 5.78 $1,019.35 $ 5.75 - --------------------------------------------------------------------------------------------------------------------------- CLASS R2 SHARES $1,000.00 $1,029.10 $ 7.06 $1,018.10 $ 7.02 - --------------------------------------------------------------------------------------------------------------------------- CLASS R3 SHARES $1,000.00 $1,027.40 $ 8.79 $1,016.40 $ 8.74 - --------------------------------------------------------------------------------------------------------------------------- </Table> 1.

Mullarkey, Roger Lob, and Christopher Mullarkey of Markston International LLC and by portfolio managers Robert H. Lyon and Jerrold K. Senser, CFA, of Institutional Capital LLC WERE THERE ANY SIGNIFICANT CHANGES IN THE MANAGEMENT OF MAINSTAY MAP FUND DURING THE 12 MONTHS ENDED OCTOBER 31, 2006? During the reporting period, Institutional Capital LLC (ICAP), a Chicago-based large-cap value oriented investment management firm, replaced Jennison Associates as one of the Fund's two subadvisors. ICAP served under an interim subadvisory agreement until shareholders approved the new subadvisory agreement at a meeting on October 5, 2006. During the reporting period, the Fund also changed its primary benchmark from the Russell Midcap(R) Index(1) to the Russell 3000(R) Index(2) to better reflect the Fund's investment style. HOW DID MAINSTAY MAP FUND PERFORM RELATIVE TO ITS BENCHMARK AND ITS PEERS DURING THE 12-MONTH REPORTING PERIOD? Excluding all sales charges, MainStay MAP Fund returned 16.80% for Class A shares, 15.94% for Class B shares, and 15.94% for Class C shares for the 12 months ended October 31, 2006. Over the same period, the Fund's Class I shares returned 17.21%, Class R1 shares returned 17.08%, Class R2 shares returned 16.80%, and Class R3 shares(3) returned 16.39%. Class A, Class I, Class R1, Class R2, and Class R3 shares outperformed--and Class B and Class C shares underperformed--the 16.37% return of Russell 3000(R) Index, the Fund's broad-based securities-market index, for the 12-month reporting period. All share classes outperformed the 14.49% return of the average Lipper(4) multi-cap core fund for the 12 months ended October 31, 2006. WHICH SECTORS OR INDUSTRIES WERE THE BIGGEST CONTRIBUTORS TO THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD AND WHICH ONES DETRACTED THE MOST? Markston International: In our portion of the Fund, the three strongest-performing sectors in absolute terms were industrials, consumer discretionary, and consumer staples. Investments in agriculture-related industrial stocks benefited from strong demand and robust prices. Investments in the health care sector, along with minor positions in cash and fixed-income, detracted from performance in our portion of the Fund. We eliminated our holding in Bristol-Myers Squibb after realizing that a turnaround would be more difficult than we originally expected. ICAP: In our portion of the Fund, health care, consumer discretionary, and utilities were the strongest-performing sectors relative to the S&P 500(R) Index.(5) Stock-specific catalysts drove the price of our stocks in these sectors higher, leading to strong absolute performance as well. Energy, materials, and telecommunication services were the weakest-performing sectors for our portion of the Fund relative to the S&P 500(R) Index. The falling price of crude oil and commodities during the period in which we subadvised a portion of the Fund diminished our returns in the energy and materials sectors. Stock selection in the telecommunication services sector negatively affected performance. DURING THE REPORTING PERIOD, WHICH STOCKS WERE STRONG CONTRIBUTORS TO THE FUND'S PERFORMANCE AND WHICH STOCKS DETRACTED? Markston International: In our portion of the Fund, positive contributors to overall performance included Monsanto, Archer-Daniels-Midland, and barge builder and operator American Commercial Lines. All three companies are related in one way or another to agriculture. Holdings that detracted from absolute performance included Vitesse Semiconductor, Boston Scientific, and Yahoo! We reduced the Fund's exposure to Vitesse Semiconductor during the third calendar quarter of 2006. The principal risk of investing in value stocks is that they may never reach what the portfolio manager believes is their full value or they may even go down in value. 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 issuers of 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.

Weak contributors were Hess, Norfolk Southern, and United States Steel. For the limited period during which we subadvised a portion of the Fund, energy and commodity prices declined, which affected some of our holdings. United States Steel was eliminated from our portion of the Fund during the reporting period. WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD? Markston International: During the reporting period, we initiated new positions in biotechnology company Celgene, industrial conglomerate General Electric, and software company Microsoft. Significant sales that either eliminated or reduced positions in our portion of the Fund included drug company Bristol-Meyers Squibb, semiconductor company Vitesse Semiconductor, and American Commercial Lines. ICAP: During the reporting period, we added retailer Target, based on expectations of increased same-store sales, which we believe may lead to improved cash flow and margins. Intercontinental Hotels Group was also added during the limited period in which we served as subadvisor to the a portion of Fund. The company operates a global hotel business that includes name brands such as Holiday Inn Express, Intercontinental, and Crowne Plaza. Intercontinental Hotels Group is experiencing strong growth in lodging revenues. We eliminated Abbott Laboratories and Caterpillar as these stocks achieved the price targets we had previously established for them. HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE OVER THE REPORTING PERIOD? Markston International: During the reporting period, our portion of the Fund increased its exposure relative to the Russell 3000(R) Index in the health care and financials sectors. We slightly decreased our weightings relative to the Index in the energy and industrials sectors. As of October 31, 2006, our portion of the Fund was slightly overweighted relative to the Index in industrials and materials. The overweighted position in the industrials sector helped performance. At the same time, our portion of the Fund was underweighted in the consumer discretionary and information technology sectors. ICAP: In our portion of the Fund, we reduced our weighting in telecommunication services relative to the S&P 500(R) Index and increased our weighting in retail stocks relative to the same Index. Both changes were the result of bottom-up stock selection. During our service as subadvisor, our portion of the portfolio was significantly underweighted relative to the S&P 500(R) Index in the information technology sector and overweighted in the energy sector. Our weightings in both of these sectors detracted from the Fund's performance. The opinions expressed are those of the portfolio managers as of the date of this report and are subject to change.

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 seven classes of shares. Class A shares, Class B shares, Class C shares and Class I shares commenced on June 9, 1999. Class R1 shares and Class R2 shares commenced on January 2, 2004. Class R3 shares commenced on April 28, 2006. 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 a 1% contingent deferred sales charge may be imposed on redemptions made within one year of purchase of Class C shares. Class I, Class R1, Class R2 and Class R3 shares are not subject to a sales charge. As approved by the Board of Trustees in 1997, Class B shares convert to Class A shares eight years after the date they were purchased. The first conversion occurred December 28, 2005. The seven 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 and Class C shares are subject to higher distribution fee rates than Class A, Class R2 and Class R3 shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I and Class R1 shares are not subject to a distribution or service fee. Class R1, Class R2 and Class R3 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, Class R2 or Class R3 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 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. 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 each day the Fund is open for business ("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, as defined in Note 3, 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 trading of the New York Stock Exchange (generally 4:00 p.m. Eastern time). Temporary cash investments acquired over 60 days prior 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 the Board of Trustees to represent fair value. Equity and non-equity securities which may be valued in this manner include, but are not limited to: a security the trading for which has been halted or suspended; a debt security that has recently gone into default and for which there is not current market quotation; a security of an issuer that has entered into a restructuring; a security that has been de-listed from a national exchange; a security the market price of which is not available from an independent pricing source or, if so provided, does not, in the opinion of the Fund's investment adviser or sub-adviser (if applicable), reflect the security's market value; and a security where the trading on that security's principal market is temporarily closed at a time when, under normal conditions, it would be open. At October 31, 2006, the Fund held securities with a value of $1,689,432 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 www.mainstayfunds.com 25 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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, as defined in Note 3, conclude that such events may have affected 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. Additionally, international equity securities are also fair valued whenever the movement of a particular index exceeds certain amounts. In such cases, the securities are fair valued by applying factors provided by a third party vendor in accordance with the Fund's policies and procedures. (B) 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 the taxable income to the shareholders of the Fund within the allowable time limits. By so doing, the Fund will be relieved from all or substantially all of federal and state income and excise taxes. Investment income received by the Fund from foreign sources may be subject to foreign income taxes. These foreign income taxes are generally withheld at the source. (C) 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 accumulated undistributed net investment income and accumulated net realized gain on investments arising from permanent differences; net assets at October 31, 2006 are not affected. <Table> <Caption> ACCUMULATED UNDISTRIBUTED ACCUMULATED NET NET INVESTMENT REALIZED GAIN ON INCOME INVESTMENTS $(96,679) $ 96,679 -------------------------------- </Table> The reclassification for the Fund is primarily due to foreign currency gain (loss) and real estate investment trusts investments. (D) 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 using the effective interest rate method. Discounts and premiums on securities, other than short-term securities, purchased for the Fund are accreted and amortized, respectively, on the effective interest rate 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. (E) 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. (F) USE OF ESTIMATES. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (G) REPURCHASE AGREEMENTS. When the Fund invests in repurchase agreements, the Fund's custodian and other banks acting in a sub-custodian capacity take possession of the collateral pledged for investments in repurchase agreements. The underlying collateral is valued daily on a mark-to-market basis to determine that the value, including accrued interest, exceeds the repurchase price. In the event of the seller's default of the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of 26 MainStay MAP Fund default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. (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) SECURITIES LENDING. In order to realize additional income 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. Collateral will consist of U.S. Government securities, cash equivalents or irrevocable letters of credit. 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 5 on page 29.) (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 which could adversely impact the Fund. NOTE 3--FEES AND RELATED PARTY TRANSACTIONS: (A) MANAGER AND SUBADVISOR. New York Life Investment Management LLC ("NYLIM" or "Manager"), a registered investment adviser and an indirect wholly-owned subsidiary of New York Life Insurance Company ("New York Life"), serves as the Fund's Manager. The Manager provides offices and conducts clerical, recordkeeping and bookkeeping services, and is responsible for the financial and accounting records required to be maintained by 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 Institutional Capital LLC (the "Subadvisors") each act as subadvisors to the Fund and manage a portion of the Fund's assets, as designated by NYLIM from time to time, subject to the oversight of NYLIM. During the period, Institutional Capital LLC replaced Jennison Associates LLC pursuant to the terms of an interim subadvisory agreement. Institutional Capital LLC was approved by the shareholders of the Fund as a subadvisor to the Fund on October 5, 2006. Please see Special Meeting of Shareholders. 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 the 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 to 0.70% on assets in excess of $1.0 billion. In addition, the Manager has entered into a written expense limitation agreement, under which the Manager has agreed to waive a portion of the Fund's management fee or reimburse the expenses of the Fund so that the total operating expenses (total annual 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, 1.35% 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 written expense limitation 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 www.mainstayfunds.com 27 NOTES TO FINANCIAL STATEMENTS (CONTINUED) the Board of Trustees. For the year ended October 31, 2006, the Manager earned fees from the Fund in the amount of $10,273,366 and recouped $222,593 which represents the total amount eligible for recoupment at October 31, 2006.

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.

Class I 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, Class R2 and Class R3 shares. Under the terms of this plan, Class R1, Class R2 and Class R3 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, Class R2 and Class R3 shares.

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. These funds paid a commitment fee, at an annual rate of .070%, up to September 6, 2006 at which time the rate changed to .060% 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 made or outstanding on the line of credit during the year ended October 31, 2006. NOTE 8--PURCHASES AND SALES OF SECURITIES (IN 000'S): During the year ended October 31, 2006, purchases and sales of securities, other than short-term securities, were $1,369,012 and $1,325,291, respectively.

NOTE 10--OTHER MATTERS: As reported in response to requests for information by various regulators, including the Securities and Exchange Commission and the New York State Attorney General, and, as noted in the notes to the year-end 2004 and 2005 financial statements of each fund of the Trust, NYLIM was previously 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 undertook a review of 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 $5.882 million to nine MainStay funds. No payment was made with respect to the Fund. NYLIM has reimbursed or paid all expenses relating to the Board of Trustees' review of this matter. 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. NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS: On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax provisions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management of the Fund is currently evaluating the impact that FIN 48 will have on the Fund's financial statements. In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of October 31, 2006, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain measurements reported in the financial statements for a fiscal period. 30 MainStay MAP 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 MAP Fund ("the Fund"), one of the funds constituting The MainStay Funds, as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-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, 2006, 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, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP Philadelphia, Pennsylvania December 21, 2006 www.mainstayfunds.com 31 BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS The Board of Trustees of the Fund approved the renewal of the Fund's Management Agreement with the Manager and the Subadvisory Agreements between the Manager and Markston International LLC ("Markston") and approved a new Subadvisory Agreement (each of the Management Agreement and the Subadvisory Agreements, an "Agreement") between the Manager and Institutional Capital LLC ("ICAP") (each of Markston and ICAP, a "Subadvisor"). In considering the new Subadvisory Agreement with ICAP, the Board considered that ICAP had entered into an agreement with an affiliate of the Manager, New York Life Investment Management Holdings LLC ("NYLIM Holdings"), providing for ICAP to become a wholly-owned indirect subsidiary of NYLIM Holdings. (This transaction closed on June 30, 2006.) In connection with the approval of each Agreement, the Trustees reviewed a wide variety of information that they had requested and received from the Manager and each Subadvisor, and data and analysis from an outside data provider and a third party consultant. The Trustees also considered additional information that they had recently reviewed in approving the initial Subadvisory Agreement with ICAP and in connection with the subsequently scheduled meeting of the Fund's shareholders relating to the engagement of ICAP as a new Subadvisor with respect to a portion of the Fund's assets. The Trustees considered a wide range of information about the previous subadvisor of that portion of the Fund's assets in determining to replace that subadvisor with ICAP. The Trustees reviewed various industry trends and regulatory developments in their deliberations. In considering the approval of each Agreement, and in evaluating the fairness of the compensation to be paid by the Fund under each Agreement, the Trustees met a number of times as a full Board, and in executive session with no Interested Trustee present, to discuss the Board's consideration of the approval of the Agreement. The Trustees considered the factors discussed below. The Trustees considered the nature, extent and quality of the services to be provided by the Manager and each Subadvisor. The Trustees reviewed the services that the Manager and each Subadvisor have historically provided to the Fund, and also generally to other series of the Trust. The Manager's services include, among others, investment management services, such as monitoring and evaluating each Subadvisor's investment program and investment results with respect to the Fund and each Subadvisor's compliance with the Fund's investment policies and restrictions. They also include administrative services, including working with other service providers of the Trust, maintaining certain Fund records, providing office space, performing clerical and bookkeeping services for the Fund, preparing Board materials and Fund filings, and otherwise managing the Trust's operations. Each Subadvisor is responsible for the day-to-day portfolio management of their respective portions of the Fund, including determining the composition of applicable assets of the Fund and the timing of the Fund's execution of the purchase and sale of these assets. In addition, the Subadvisors provide reports to the Manager and review certain aspects of Fund filings. The Trustees also considered the Manager's and each Subadvisor's management, personnel, resources, operations and portfolio management capabilities. The Board reviewed information about each Subadvisor's brokerage practices, including, but not limited to, reports related to best execution of portfolio trades. The Trustees noted that the Fund's assets represented a significant portion of Markston's assets under management, and a smaller portion of ICAP's assets under management. The Trustees received information about the Manager's supervision of the Fund's service providers, the Manager's attention to its compliance program and those of the Trust, each Subadvisor and certain other service providers, as well as each Subadvisor's attention to its compliance program. The Trustees noted the generally favorable results of a third party review of the services and communications that NYLIM Service Company LLC, an affiliate of the Manager and each Subadvisor, has provided to Trust shareholders. The Trustees, including the Non-Interested Trustees, unanimously concluded that, overall, the nature, extent and quality of the services expected to be provided by the Manager and each Subadvisor were such that, in the context of the Board's overall review of various factors, each Agreement should be renewed. The Board also considered the proposed subadvisory fee rate payable by the Manager to each Subadvisor under the Subadvisory Agreements. The Board noted that the subadvisory fee arrangement between the Manager and each Subadvisor included breakpoints based on the amount of assets in its portion of the Fund's portfolio. The Board also considered and compared the rate of each Subadvisor's proposed subadvisory fee to advisory fees paid by funds identified by fund data services as comparable to the Fund. Based on these considerations, the Board concluded that each Subadvisor's proposed subadvisory fee rate under its Agreement was reasonable in comparison to other subadvisory fee rates. The Trustees reviewed the investment performance of the Fund over various time periods and compared that performance to that of funds in groups that the Trustees concluded, in consultation with an outside data provider and a third party consultant, were appropriate comparison groups for the Fund. The Board took into consideration information it received on, among other things, the favorable long- and short-term performance of the Fund, the favorable performance of Markston, and ICAP's performance in managing the ICAP Select Equity Fund (another mutual fund advised by ICAP with an investment focus similar to the manner in which ICAP manages its portion of the Fund), noting that ICAP's performance compared favorably over certain time periods to funds viewed as comparable by a third party data provider. The Board further considered the experience level, 32 MainStay MAP Fund tenure and compensation of the management team of each Subadvisor. The Board concluded that the investment program of each Subadvisor appeared appropriate to complement the investment program of the other Subadvisor. The Trustees considered the cost to the Manager of each Agreement and the profitability to the Manager and its affiliates of the relationship with the Fund over various time periods. In this regard, the Board considered the effect that the pending affiliation between ICAP and the Manager may have on the Manager's future profitability with respect to this Fund. In reviewing profitability information, the Trustees reviewed, among other things, information about the allocation of expenses among the Manager and its affiliates, and the subadvisory fee payments made by the Manager to each Subadvisor. The Trustees were provided information indicating that the profitability to the Manager and its affiliates from the Agreements, and from the overall relationship with the Trust, was low. The Trustees considered other benefits that the Manager and its affiliates receive from the relationship with the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder Services receive in exchange for services they provide to the Funds, and certain benefits from soft dollar arrangements. The Trustees acknowledged certain benefits to the reputation of the Manager and the Trust from their association with each other. The Trustees considered information about transfer agency expenses and their effect on the Fund's overall expenses. They noted that, across the Trust (though not every series or share class), transfer agency fees tended to be relatively high and, therefore, adversely affected gross expense ratios. Noting that the Trust historically permitted smaller investor accounts, the Trustees discussed that the Board had approved certain measures and the Manager had taken certain actions intended to increase the average size of shareholder accounts, including imposing higher investment minimums for some share classes. The Trustees discussed additional measures that may increase average shareholder account size and/or otherwise reduce the Trust's transfer agency expenses. The Trustees discussed the extent to which economies of scale were projected by the Manager to be realized as the Fund's assets, or the assets of the Trust overall, increase. The Trustees noted, in particular, the plans of the Manager and its affiliates for marketing and distributing the shares of the various series of the Trust. They noted the contractual breakpoint that would reduce the Fund's management fee at asset levels above the breakpoint and the fact that the breakpoint was intended to provide that shareholders would share in benefits from economies of scale obtained through the growth in the Fund's assets. The Trustees noted that the Fund's management fee rate had been reduced by the breakpoint schedule applicable to the Fund. The Trustees reviewed information about the potential effect of asset growth on Fund expenses, the difficulty of forecasting its effect on the profitability of the Manager and its affiliates, and the management fee breakpoints applicable to the Fund and certain other funds in comparison groups. It was noted that, to the extent the Fund's gross expenses currently were higher than its net expenses, the reduction of the Fund's gross expenses through the achievement of economies of scale might benefit the Manager by reducing the expenses the Manager must reimburse to the Fund rather than directly benefiting the Fund by reducing its net expenses. The Trustees considered information about services provided by other investment advisers of funds having investment objectives and policies similar to the Fund's. The Board received and reviewed, among other things, comparative data on various types of Fund expenses. In considering the management fees paid by 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 the Fund's. Although the Trustees received fee and expense data with respect to other clients of the Manager generally, they were advised that no other client of the Manager had an investment strategy similar to that of the Fund. The Trustees considered the current and proposed contractual and net management fees, its anticipated gross and net expense ratio, and various components of the expense ratio, in comparison to other funds in comparison groupings. The Trustees generally acknowledged the historical relationships among the Manager, each Subadvisor and the Trust. The Trustees noted the Manager's agreement to maintain the limit on the Fund's net expenses at a certain 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 legal counsel to the Non-Interested Trustees. The materials and other information also were considered by the Non-Interested Trustees meeting separately and with independent legal 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. This summary describes the most important, but not all, of the factors considered by the Trustees in considering each Agreement. On the basis of their review, the Trustees, including all of the Non-Interested Trustees, unanimously concluded that each factor they considered, in the context of all the other factors they considered, favored renewal or approval, as applicable, of each Agreement, and it was the unanimous judgment of the Trustees and the Non-Interested Trustees that approval of each Agreement 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 end (October 31, 2006) as to the federal tax status of dividends paid by the Fund during such fiscal year. Accordingly, the Fund paid long-term capital gain distributions of $45,058,082. The dividends paid by the Fund during the fiscal year ended October 31, 2005, should be multiplied by 46.2% to arrive at the amount eligible for qualified dividend income and 45.6% for the corporate dividends received deduction. In January 2007, shareholders will receive on IRS Form 1099-DIV or substitute Form 1099 the federal tax status of the distributions received by shareholders in calendar year 2006. The amounts that will be reported on such 1099-DIV will be the amounts you are to use on your federal income tax return and will differ from the amounts which we must report for the Fund's fiscal year ended October 31, 2006.

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.

Alan R. Latshaw is the audit committee financial expert and is considered independent. ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES. (a) Audit Fees The aggregate fees billed for the fiscal year ended October 31, 2006 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 $812,750. The aggregate fees billed for the fiscal year ended October 31, 2005 for professional services rendered by 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 (includes $38,500 for an additional audit of MainStay Large Cap Growth Fund). (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) $0 for the fiscal year ended October 31, 2006, and (ii) $15,000 for the fiscal year ended October 31, 2005. These audit-related services include review of financial highlights for Registrant's registration statements and issuance of consents to use of the auditor's reports. (c) Tax Fees The aggregate fees billed for professional services rendered by KPMG for tax compliance, tax advice, and tax planning were: (i) $90,100 during the fiscal year ended October 31, 2006, and (ii) $95,700 during the fiscal year ended October 31, 2005. These services primarily included preparation of federal, state and local income tax returns and excise tax returns, as well as services relating to excise tax distribution requirements. (d) All Other Fees The aggregate fees billed for products and services provided by KPMG, other than the services reported in paragraphs (a) through (c) of this Item were: (i) $0 during the fiscal year ended October 31, 2006, and (ii) $0 during the fiscal year ended October 31, 2005. (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. (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, 2006 and October 31, 2005 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) $25,000 for the fiscal year ended October 31, 2006, and (ii) $15,000 for the fiscal year ended October 31, 2005. (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, 2006 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.
